DETAILED DESCRIPTION

The following description provides specific application scenarios and requirements of this disclosure, with the purpose of enabling a person skilled in the art to manufacture and use the contents of this disclosure. For a person skilled in the art, various local modifications to the disclosed embodiments are apparent, and without departing from the spirit and scope of this disclosure, the general principles defined herein can be applied to other embodiments and applications. Therefore, this disclosure is not limited to the embodiments shown, but is consistent with the broadest scope of the claims.

The terminology used here is only for the purpose of describing specific example embodiments and is not restrictive. For example, unless explicitly stated otherwise in the context, the singular forms “one,” “a,” and “the” used here can also include plural forms. When used in this disclosure, the terms “comprising,” “including,” and/or “containing” mean that the associated features, integers, steps, operations, elements, and/or components are present, but do not exclude the presence of one or more other features, integers, steps, operations, elements, components, and/or groups, or the addition of other features, integers, steps, operations, elements, components, and/or groups in the system/method.

In view of the following description, the features of this disclosure and other features, as well as the operation and function of the related structural elements, and the combination and manufacturability of the components, can be significantly improved. With reference to the drawings, all of these form part of this disclosure. However, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this disclosure. It should also be understood that the drawings are not drawn to scale.

The flowcharts used in this disclosure illustrate operations implemented by the system according to some exemplary embodiments of this disclosure. It should be clearly understood that the operations in the flowcharts may not be implemented in order. On the contrary, the operations may be performed in reverse order or simultaneously. In addition, one or more additional operations may be added to the flowcharts. One or more operations may be removed from the flowcharts.

In this disclosure, “X comprises at least one of A, B, or C” means that X comprises at least A, or X comprises at least B, or X comprises at least C. That is, X may comprise any one of A, B, or C alone, or any combination of A, B, and C together, as well as other possible contents/elements. Any combination of A, B, and C may be A, B, C, AB, AC, BC, or ABC. It should also be understood that the term “and/or” as used in this disclosure and claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

In this disclosure, unless explicitly stated otherwise, the relationships generated between structures may be direct or indirect. For example, when describing “A is connected to B,” unless it is explicitly stated that A is directly connected to B, it should be understood that A may be directly connected to B or indirectly connected to B. Similarly, when describing “A is on B,” unless it is explicitly stated that A is directly on B (A and B are adjacent and A is above B), it should be understood that A may be directly on B or indirectly on B (other elements are between A and B, and A is above B), and so on.

Some people choose to spend their leisure time working on puzzles at a puzzle table. In the existing technology, puzzle tables generally cannot be folded, resulting in a large overall size, which makes the puzzle table inconvenient to carry when going out and difficult to store. For some foldable puzzle tables, the joint of the table-top often has a relatively large gap, which creates a risk of puzzle pieces falling into the joint gap, affecting the progress of the puzzle game and the user's gaming experience. In addition, the folding method of such puzzle tables often results in an unsmooth folding operation. At the same time, these puzzle tables also suffer from structural instability, unreasonable design, and other issues.

Therefore, there is a need to provide a table-top foldable table in which the joint of the table-top has no gap or a nearly gapless joint, and which facilitates folding of the table-top. At the same time, the structural instability and unreasonable design issues are improved to meet the practical needs of users and enhance the user experience.

In view of this, the present disclosure provides a table-top foldable table. The table includes a hinge, a first table-top, and a second table-top. The first table-top is rotatably connected to the hinge. The second table-top is rotatably connected to the hinge. The first table-top is slidably connected to the second table-top through the hinge. The table-top, when deployed, includes a closed state and a foldable state. In the closed state, the second table-top slides to a first position relative to the first table-top, and the first table-top and the second table-top are aligned. In the foldable state, the second table-top slides to a second position relative to the first table-top, and the first table-top and the second table-top are separated and foldable around the hinge. In the closed state, the joint between the first table-top and the second table-top has no gap or a nearly gapless joint, preventing objects such as puzzle pieces from falling into the joint gap. In the foldable state, there is a spacing between the first table-top and the second table-top, which can reduce or eliminate mutual interference between the first table-top and the second table-top during the folding process, facilitating the user in folding the table-top. The table-top is configured to switch between the closed state and the foldable state, thereby enriching the functionality of the table-top, facilitating folding and storage, and improving the user's experience with the table. It should be noted that the foldable state herein refers to a state of the table-top when it can be folded but is not folded.

Below, the technical solutions of the embodiments of this disclosure will be described in detail with reference to the drawings.

FIG. 1 shows a three-dimensional schematic diagram of a table provided according to some exemplary embodiments of this disclosure. FIG. 2 shows an exploded structural schematic diagram of a table provided according to some exemplary embodiments of this disclosure. FIG. 3 shows a schematic diagram of the back of the table provided according to some exemplary embodiments of this disclosure with two drawers removed. FIG. 4 shows a schematic diagram of the process of switching the table provided according to some exemplary embodiments of this disclosure between different structural states. As shown in FIG. 1 to 4, the table 001 includes a first table-top 100 and a second table-top 200. The front surface of the first table-top 100 and the front surface of the second table-top 200 form the table-top of the table 001. When the table 001 is in use, the table-top is deployed, and the front surface of the first table-top 100 and the front surface of the second table-top 200 can face upward, thereby supporting various items. For example, when the table 001 is a puzzle table, correspondingly, the front surfaces of the first table-top 100 and the second table-top 200 can support puzzle pieces.

In some exemplary embodiments, the table 001 includes a mat laid on the table-top, such as a silicone mat or a felt mat (not shown in the figures). The mat can be disposable or used for a short term, and it can also be replaced or cleaned. When the table 001 is used for puzzle games, a felt mat can be laid on the table-top to prevent puzzle pieces from slipping.

In some exemplary embodiments, the main body of table 001 is made of a single material. In some exemplary embodiments, the material of the main body of the table 001 can use a combination of various materials depending on its structural function and usage requirements. For example, the material of the main body of the table 001 can be selected from wear-resistant, easy-to-clean plastics (such as ABS, PP, or PC), wood composite boards, or laminated boards, to ensure flatness and surface smoothness during puzzle assembly. It is understood that other materials are also within the scope of this disclosure. The following description takes the material of the main body of the table 001 as plastic as an example.

In some exemplary embodiments, the first table-top 100 and the second table-top 200 have symmetrical structures. In some exemplary embodiments, the first table-top 100 and the second table-top 200 have different structures.

In some exemplary embodiments, the front surface of the first table-top 100 is rectangular, and the front surface of the second table-top 200 is also rectangular. In some exemplary embodiments, the front surface of the first table-top 100 is semicircular, and the front surface of the second table-top 200 is also semicircular, so that the front surface of the table-top is circular when deployed; alternatively, the front surfaces of the first table-top 100 and the second table-top 200 can be any matching irregular shapes. The following description takes the case where both the first table-top 100 and the second table-top 200 are rectangular as an example. The thickness of the first table-top 100 and the second table-top 200 can be between 1 mm and 10 mm. For example, the thickness of the first table-top 100 and the second table-top 200 can be 1 mm, 1.5 mm, 1.8 mm, 2 mm, 2.2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm. The following description takes the thickness of the first table-top 100 and the second table-top 200 as 2 mm as an example. It is understood that the thickness of the first table-top 100 and the second table-top 200 can be designed according to actual needs, which will not be further elaborated herein.

In some exemplary embodiments, as shown in FIG. 4, the first table-top 100 further includes a first end 141 and a second end 142. The second table-top 200 further includes a third end 241 and a fourth end 242. When the table-top is deployed, the first end 141 and the third end 241 are adjacent and located at the middle portion of the table-top, and the second end 142 and the fourth end 242 are located at the two ends of the table-top. When the table-top is folded, the first end 141 and the third end 241 are adjacent, and the second end 142 and the fourth end 242 are adjacent.

In some exemplary embodiments, when the table 001 is in use and the table-top is deployed, the side wall 110 of the first table-top 100 surrounds the first table-top 100, and the side wall 210 of the second table-top 200 surrounds the second table-top 200.

Further, as shown in FIG. 1 to 4, the side wall 110 of the first table-top 100 includes a first side wall 111, a second side wall 112, a third side wall 113, and a fourth side wall 114. The first side wall 111, the second side wall 112, the third side wall 113, and the fourth side wall 114 are sequentially connected, and the fourth side wall 114 is also connected to the first side wall 111, so that the side wall 110 of the first table-top 100 surrounds the front surface of the first table-top 100. Among them, the second side wall 112 may be located at the first end 141, and the fourth side wall 114 may be located at the second end 142.

The side wall 210 of the second table-top 200 includes a fifth side wall 211, a sixth side wall 212, a seventh side wall 213, and an eighth side wall 214. The fifth side wall 211, the sixth side wall 212, the seventh side wall 213, and the eighth side wall 214 are sequentially connected, and the fifth side wall 211 is also connected to the eighth side wall 214, so that the side wall 210 of the second table-top 200 surrounds the front surface of the second table-top 200. Among them, the sixth side wall 212 is located at the third end 241, and the eighth side wall 214 is located at the fourth end 242.

In some exemplary embodiments, as shown in FIG. 1 to 4, the first table-top 100 includes at least one drawer, namely the first drawer 102. The second table-top 200 includes at least one drawer, namely the second drawer 202. For example, the first table-top 100 includes two first drawers 102, and the second table-top 200 includes two second drawers 202. The drawers can be used to store puzzle pieces, thereby facilitating the organization of the puzzle pieces. Further, the bottom surface (back surface) of the first table-top 100 is provided with a first slide groove 104 for the first drawer 102 to slide; the opening of the first slide groove 104 is arranged on the fourth side wall 114. Correspondingly, the drawer opening of the first drawer 102 is located on the fourth side wall 114. The bottom surface (back surface) of the second table-top 200 is provided with a second slide groove 204 for the second drawer 202 to slide; the opening of the second slide groove 204 is arranged on the eighth side wall 214. Correspondingly, the drawer opening of the second drawer 202 is located on the eighth side wall 214. In some exemplary embodiments, the number of first drawers 102 is two, and the number of second drawers 202 is two. The first table-top 100 has a first receiving compartment 1021 for storing the first drawer 102, and the second table-top 200 has a second receiving compartment 2021 for storing the second drawer 202. There may be two first receiving compartments 1021 and two second receiving compartments 2021. Each first receiving compartment 1021 has a first slide groove 104 on the left side thereof and a first slide groove 104 on the right side thereof. Each second receiving compartment 2021 has a second slide groove 204 on the left side thereof and a second slide groove 204 on the right side thereof. Therefore, the number of first slide grooves 104 is four, and the number of second slide grooves 204 is four. It should be noted that the thickness of the first drawer 102 is 0.8 mm to 2.5 mm, for example, greater than 1.5 mm and less than the thickness of the side wall 110 of the first table-top 100. The thickness of the second drawer 202 is 0.8 mm to 2.5 mm, for example, greater than 1.5 mm and less than the thickness of the side wall 210 of the second table-top 200. For example, if the thickness of the first table-top 100 and the second table-top 200 is 2 mm, then the thickness of the first drawer 102 and the second drawer 202 can be 1.8 mm. In some exemplary embodiments, the thickness of the first drawer 102 or the second drawer 202 can be 0.8 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.8 mm, 2.0 mm, 2.3 mm, or 2.5 mm. It is understood that the above thicknesses can be designed according to actual needs, which will not be further elaborated herein.

As shown in FIG. 3, in order to prevent the first drawer 102 from sliding out of the drawer opening, the first table-top 100 further includes a drawer limiting structure. Specifically, a first protrusion 1041 is provided on the inner wall of the first slide groove 104, and a first recess 1051 is provided on the outer side wall 105 of the first drawer 102. A guiding inclined surface is provided on the first protrusion 1041 in the direction facing the opening of the first slide groove 104. During the sliding of the first drawer 102 along the first slide groove 104 toward the second side wall 112, the end portion 1052 of the side wall 105 of the first drawer 102 first contacts the first protrusion 1041. The first protrusion 1041 abuts the side wall 105, and the side wall 105 slightly deforms due to the pressure from the first protrusion 1041, while the sliding friction resistance of the first drawer 102 within the first slide groove 104 increases. The position of the first recess 1051 on the side wall 105 of the first drawer 102 corresponds to the position of the first protrusion 1041 on the first slide groove 104. That is, the distance from the first protrusion 1041 to the end of the first slide groove is the same as the distance from the first recess 1051 to the end portion 1052 of the side wall 105 of the first drawer 102. In other words, the distance from the first protrusion 1041 to the first end 141 is the same as the distance from the first recess 1051 to the first end 141. The shapes of the first protrusion 1041 and the first recess 1051 are matched. In this way, when the first drawer 102 continues to slide toward the second side wall 112 to the end of the first slide groove 104, the first protrusion 1041 precisely fits into the first recess 1051, thereby securing the first drawer 102.

Similarly, in order to prevent the second drawer 202 from sliding out of the drawer opening, the second table-top 200 further includes a drawer limiting structure. Specifically, a second protrusion 2041 is provided on the inner wall of the second slide groove 204, and a second recess 2051 is provided on the outer side wall 205 of the second drawer 202. A guiding inclined surface is provided on the second protrusion 2041 in the direction facing the opening of the second slide groove 204. During the sliding of the second drawer 202 along the second slide groove 204 toward the sixth side wall 212, the end portion 2052 of the side wall 205 of the second drawer 202 first contacts the second protrusion 2041. The second protrusion 2041 abuts the side wall 205, and the side wall 205 slightly deforms due to the pressure from the second protrusion 2041, while the sliding friction resistance of the second drawer 202 within the second slide groove 204 increases. The position of the second recess 2051 on the side wall 205 of the second drawer 202 corresponds to the position of the second protrusion 2041 on the second slide groove 204. That is, the distance from the second protrusion 2041 to the end of the second slide groove is the same as the distance from the second recess 2051 to the end portion 2052 of the side wall 205 of the second drawer 202. In other words, the distance from the second protrusion 2041 to the third end 241 is the same as the distance from the second recess 2051 to the third end 241. The shapes of the second protrusion 2041 and the second recess 2051 are matched. In this way, when the second drawer 202 continues to slide toward the sixth side wall 212 to the end of the second slide groove 204, the second protrusion 2041 precisely fits into the second recess 2051, thereby securing the second drawer 202.

It can be understood that the number of first protrusions 1041 corresponds to the number of first slide grooves 104; that is, if the number of first slide grooves 104 is four, then the number of first protrusions 1041 is also four. Similarly, the number of second protrusions 2041 corresponds to the number of second slide grooves 204; that is, if the number of second slide grooves 204 is four, then the number of second protrusions 2041 is also four. In some exemplary embodiments, each first slide groove 104 has two or more first protrusions 1041 on its inner wall, and each second slide groove 204 has two or more second protrusions 2041 on its inner wall.

In some exemplary embodiments, as shown in FIG. 1 to 4, the first table-top 100 includes a first handle 103, and the second table-top 200 includes a second handle 203. When the table-top is folded, the first handle 103 and the second handle 203 come close together, facilitating the user to grip them. That is, when the table-top is folded, the user can hold the first handle 103 and the second handle 203 with one hand, making it convenient for the user to carry the folded table 001. When the table-top is deployed, the first handle 103 and the second handle 203 are located at the two ends of the table-top. Specifically, the first handle 103 is provided on the second end 142 of the first table-top 100, and the second handle 203 is provided on the fourth end 242 of the second table-top 200. In this way, when the table-top is folded, the first handle 103 and the second handle 203 can be brought together. It is understood that when the table-top is deployed, the first handle 103 does not affect the movement of the first drawer 102, and the second handle 203 does not affect the movement of the second drawer 202.

In some exemplary embodiments, the first handle 103 spans the first table-top 100 and the second table-top 200. The second handle 203 also spans the first table-top 100 and the second table-top 200. In some exemplary embodiments, the first handle 103 and the second handle 203 can be independent structures, detachable structures, or a single structure. The following provides a detailed description of the different structures.

When the first handle 103 and the second handle 203 are independent structures, the first handle 103 and the second handle 203 are different and each constitutes a complete handle structure. Specifically, when the table-top is folded, one end of the first handle 103 is fixed to the fourth side wall 114, and the other end extends and is fixed to the eighth side wall 214. One end of the second handle 203 is fixed to the eighth side wall 214, and the other end extends and is fixed to the fourth side wall 114. When the table-top is folded, the first handle 103 and the second handle 203 come close together, allowing the user to hold both handles with one hand for stable lifting. When the table-top is deployed, one end of the first handle 103 remains fixed to the fourth side wall 114, while the other end is in an “open” state, i.e., this end is separated from the second table-top and in a relaxed state, without obstructing the use of the first table-top 100 and the second table-top 200. Similarly, when the table-top is deployed, one end of the second handle 203 remains fixed to the eighth side wall 214, while the other end is in an “open” state, i.e., this end is separated from the first table-top and in a relaxed state, without obstructing the use of the first table-top 100 and the second table-top 200. This design allows the first handle 103 and the second handle 203 to naturally hang down or be stored when not in use, avoiding any impact on the flatness of the table-top.

When the first handle 103 and the second handle 203 are a single structure, the first handle 103 and the second handle 203 are the same handle, which can span the first table-top 100 and the second table-top 200. Specifically, when the table-top is folded, both ends of the handle are fixed to the fourth side wall 114 and the eighth side wall 214, respectively, allowing the user to carry the entire table with one hand via this handle. When the table-top is deployed, one end of the handle remains fixed to the fourth side wall 114 or the eighth side wall 214, while the other end is in an “open” state, i.e., in a relaxed state.

When the first handle 103 and the second handle 203 are detachable structures, the first handle 103 and the second handle 203 form a continuous, complete handle with the detachable structure. In this case, one of the first handle 103 and the second handle 203 can be omitted. Specifically, when the table-top is folded, the first handle 103 and the second handle 203 form a continuous, complete handle through the detachable structure. The user can hold a single integrated handle to carry the folded table, providing more comfortable grip and more evenly distributed force. The detachable structure can be at least one of a buckle, magnetic attraction, or plug-in structure. When the table-top is deployed, the detachable structure is separated, and the first handle 103 and the second handle 203 are independent. At this time, the handles can be retracted, folded, or kept in the deployed state to avoid interfering with the use of the table-top.

Further, the first handle 103 is located on the fourth side wall 114, and the second handle 203 is located on the eighth side wall 214. It is understood that, in some exemplary embodiments, the first handle 103 and the second handle 203 are located on the same side of the table-top. Specifically, the first handle 103 may be located on the third side wall 113, and the second handle 203 may be located on the seventh side wall 213; or the first handle 103 may be located on the first side wall 111, and the second handle 203 may be located on the fifth side wall 211.

In some exemplary embodiments, a reinforcing rib can be provided on the side wall 110 of the first table-top 100 at the location where the first handle 103 is installed. A reinforcing rib may also be provided on the side wall 210 of the second table-top 200 at the location where the second handle 203 is installed.

To enhance the structural strength at the handles, reinforcing ribs are designed on the inner side of the side wall where the handles are mounted. Specifically, taking the first handle 103 mounted on the fourth side wall 114 and the second handle 203 mounted on the eighth side wall 214 as an example, a reinforcing rib is provided on the side of the fourth side wall 114 near the first drawer 102 at the installation position of the first handle 103 to strengthen the first handle 103. Similarly, a reinforcing rib is provided on the side of the eighth side wall 214 near the second drawer 202 at the installation position of the second handle 203 to strengthen the second handle 203. It should be noted that the thickness of the reinforcing rib can be 1.1 mm. In some exemplary embodiments, the thickness of the reinforcing rib can be between 0.7 mm and 3.0 mm; for example, the thickness of the reinforcing rib can be 0.7 mm, 0.8 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.8 mm, 2.0 mm, or 3 mm.

In some exemplary embodiments, as shown in FIG. 1 to 4, when the table-top is folded, the front surface of the first table-top 100 faces the front surface of the second table-top 200. In this way, the user can fold the deployed table-top by rotating the first table-top 100 and/or the second table-top 200 upward, facilitating the folding operation.

In some exemplary embodiments, when the table-top is folded, the front surface of the first table-top 100 can face away from the front surface of the second table-top 200. Correspondingly, the back surfaces of the first table-top 100 and the second table-top 200 can each be provided with a chamfer, so that during the folding of the table-top, the risk of interference between the first table-top 100 and the second table-top 200 can be reduced.

In some exemplary embodiments, as shown in FIG. 1 to 4, the first table-top 100 includes a first gallery rail 151 located at the edge of the first table-top 100, and the second table-top 200 includes a second gallery rail 251 located at the edge of the second table-top 200.

Specifically, the first gallery rail 151 is located on the front surface of the first table-top 100, and the second gallery rail 251 is located on the front surface of the second table-top 200. The first gallery rail 151 has a notch above the second side wall 112, and the second gallery rail 251 has a notch above the sixth side wall 212. When the table-top is in the closed state, the end of the first gallery rail 151 abuts the end of the second gallery rail 251, and the front surface of the first table-top 100 aligns with the front surface of the second table-top 200, so that the end of the first gallery rail 151 and the end of the second gallery rail 251 can enclose the table-top. This can reduce the risk of objects such as puzzle pieces falling off the table-top.

FIG. 5 shows an enlarged view of part C illustrated in FIG. 4. FIG. 6A shows a schematic diagram of the changes in a local cross-sectional structure of the table when switching between different structural states, as illustrated in FIG. 4. In this context, part C in FIG. 5 corresponds to part C in FIG. 4. The A-A cross-section in FIG. 6A corresponds to the A-A section in FIG. 4, and the B-B cross-section in FIG. 6A corresponds to the B-B section in FIG. 4. As shown in FIG. 2 to 4, in some exemplary embodiments, the first gallery rail 151 includes a first abutting surface 1512 parallel to the front surface of the first table-top 100, and the second gallery rail 251 includes a second abutting surface 2512 parallel to the front surface of the second table-top 200. After the table-top is folded, the first abutting surface 1512 abuts the second abutting surface 2512, which can reduce the occupied space of the table 001 after folding the table-tops.

In some exemplary embodiments, as shown in FIG. 4 and FIG. 6A, at least one of the first gallery rail 151 and the second gallery rail 251 is provided with a chamfer, so that the first gallery rail 151 and the second gallery rail 251 can avoid each other during the folding process of the table-top. Specifically, the end of the first gallery rail 151 includes a first chamfer 1511, and the end of the second gallery rail 251 includes a second chamfer 2511. During the folding process of the table-top, the first chamfer 1511 and the second chamfer 2511 reduce the risk of interference between the ends of the first gallery rail 151 and the second gallery rail 251.

In some exemplary embodiments, as shown in FIG. 4 to 6A, during the folding process of the table-top, the first table-top 100 can rotate relative to the second table-top 200 around a first axis and a second axis. On the side of the table 001 where the table-top is provided, the maximum distance from the first axis to the second side wall 112 is denoted as L1, and the maximum distance from the second axis to the sixth side wall 212 is denoted as L2. The sum of L1 and L2 is less than or equal to the distance L between the first axis and the second axis, i.e., L1+L2≤L, thereby reducing the risk of interference between the first table-top 100 and the second table-top 200 during the folding process of the table-top. The arrangement of the first chamfer 1511 can reduce the value of L1, and the arrangement of the second chamfer 2511 can reduce the value of L2, so that during the folding process of the table-top, the first table-top 100 and the second table-top 200 can avoid each other. In this context, when the table-top is in the foldable state, the first axis can coincide with the central axis of the first rotation shaft 310 described below, and the second axis can coincide with the central axis of the second rotation shaft 320 described below.

In some exemplary embodiments, the table 001 includes a locking mechanism (not shown in the figure). The locking mechanism includes a first locking mechanism and a second locking mechanism, one of which is disposed on the first table-top and the other correspondingly disposed on the second table-top, and the first locking mechanism cooperates with the second locking mechanism. The locking mechanism is configured to restrict the relative movement between the first table-top 100 and the second table-top 200 when the first table-top 100 and the second table-top 200 are folded. For example, it can prevent the first table-top 100 and the second table-top 200 from opening; it can also prevent misalignment between the first table-top 100 and the second table-top 200 during folding, thereby avoiding excessive wear between the hinge and the first table-top 100 and the second table-top 200. The locking mechanism can be implemented in various ways, such as at least one of a buckle structure, a magnetic attraction structure, a clamping structure, or a strap structure. The following provides an explanation of each structure.

The locking mechanism may be a buckle structure. The buckle structure is divided into a male buckle and a female buckle. One of the male buckle and the female buckle is fixedly disposed on the first table-top 100, and the other is fixedly disposed on the second table-top 200. When the table-top is folded, the male buckle and the female buckle are mechanically engaged, thereby firmly locking the first table-top 100 and the second table-top 200 and preventing the first table-top 100 and the second table-top 200 from opening.

The locking mechanism may be a magnetic attraction structure. The magnetic attraction structure includes a first magnet and a second magnet. One of the first magnet and the second magnet is fixedly disposed on the first table-top 100, and the other is fixedly disposed on the second table-top 200. When the table-top is folded, the first magnet and the second magnet are opposite to each other and generate magnetic attraction, thereby stably fixing the first table-top 100 and the second table-top 200 and preventing the first table-top 100 and the second table-top 200 from opening.

The locking mechanism may be a clamping structure. The clamping structure includes an elastic clamping body. The elastic clamping body is fixedly disposed on the first table-top 100 or the second table-top 200. When the table-top is folded, the elastic clamping body clamps onto the side edge or the gallery rail of the other table-top, thereby achieving fixation of the first table-top 100 and the second table-top 200 through elastic clamping force, preventing the first table-top 100 and the second table-top 200 from opening.

The locking mechanism may be a strap structure. The strap structure includes a flexible strap and a connecting member. One end of the strap is fixed on the first table-top 100, and the other end is detachably fixed on the second table-top 200 through the connecting member, or a fixed end is provided at the middle portion of the strap, and both ends can be wound around the folded table-top for binding. When the table-top is folded, the strap surrounds the folded body and is locked by means such as Velcro, buckle, or knotting, thereby binding the first table-top 100 and the second table-top 200 together and preventing them from opening.

It can be understood that the position of the locking mechanism can be arbitrarily set to adapt to different structural designs, usage habits, and appearance requirements. For example, the locking mechanism may be disposed on the fourth side wall 114 and the eighth side wall 214.

When the table-top is in the deployed state, it may include a closed state and a foldable state. It should be noted that the table-top in the foldable state is still in the deployed state.

As shown in FIG. 1 to 6A, in the closed state, the second table-top 200 slides to the first position relative to the first table-top 100, and the first table-top 100 and the second table-top 200 are closed together. At this time, a user can play a jigsaw puzzle game on the table-top. The joint between the first table-top 100 and the second table-top 200 has no gap or approximately no gap, which can prevent puzzle pieces or other objects from falling into the gap. It is difficult to fold the table-top when it is in the closed state. Furthermore, when the table-top is in the closed state, the second side wall 112 abuts against the sixth side wall 212.

In the foldable state, the second table-top 200 slides to the second position relative to the first table-top 100, and the first table-top 100 and the second table-top 200 are separated and foldable. At this time, there is a spacing between the first table-top 100 and the second table-top 200, which can reduce or eliminate mutual interference between the first table-top 100 and the second table-top 200 during the folding process of the table-top, facilitating the user to fold the table-top. Furthermore, when the table-top is in the foldable state, the second side wall 112 and the sixth side wall 212 are separated and opposite to each other.

The table-top is configured to be switchable between the closed state and the foldable state, thereby enriching the functions of the table-top and improving the user experience of the table 001.

In some exemplary embodiments, during the process of switching between the closed state and the foldable state of the table-top, the sliding stroke range of the second table-top 200 relative to the first table-top 100 is 5 mm to 50 mm. That is, in the foldable state, the spacing distance range between the second side wall 112 and the sixth side wall 212 is 5 mm to 50 mm.

In some exemplary embodiments, as shown in FIG. 4 to 6A, the second side wall 112 is provided with a first anti-misalignment structure 130 (anti-dislocation structure). The sixth side wall 212 is provided with a second anti-misalignment structure 230. In the closed state, the first anti-misalignment structure 130 and the second anti-misalignment structure 230 are engaged to limit the relative displacement of the first table-top 100 and the second table-top 200 in both directions perpendicular to the table-top. In the foldable state, the first anti-misalignment structure 130 and the second anti-misalignment structure 230 are disengaged, making the table-top foldable.

When a user plays a jigsaw puzzle game, the back surface of the table-top can directly face ground. When the ground is uneven, the first table-top 100 and the second table-top 200 may become misaligned. Through the mutually engaged first anti-misalignment structure 130 and second anti-misalignment structure 230, the stability of the connection structure between the first table-top 100 and the second table-top 200 can be enhanced. This can reduce the risk of misalignment of the first table-top 100 and the second table-top 200 in the direction perpendicular to the table-top.

In some exemplary embodiments, the connection structure between the first table-top 100 and the second table-top 200 may have two degrees of rotational freedom, that is, the first table-top 100 and the second table-top 200 can rotate relative to each other around the following first rotation shaft 310 and second rotation shaft 320, thereby making the connection structure between the first table-top 100 and the second table-top 200 more flexible. This may cause a risk of misalignment of the first table-top 100 and the second table-top 200 in the direction perpendicular to the table-top. The first rotation shaft 310, the second rotation shaft 320, and the mutually engaged first anti-misalignment structure 130 and second anti-misalignment structure 230 can make the first table-top 100 and the second table-top 200 kept relatively fixed, thereby reducing the risk of misalignment of the first table-top 100 and the second table-top 200 in the direction perpendicular to the table-top. The first anti-misalignment structure includes at least one of a first protruding portion and a first limiting slot. That is, in some exemplary embodiments, the first anti-misalignment structure may include the first protruding portion. In some exemplary embodiments, the first anti-misalignment structure may include the first limiting slot. In some exemplary embodiments, the first anti-misalignment structure may include both the first protruding portion and the first limiting slot. The second anti-misalignment structure 230 corresponds to the first anti-misalignment structure 130. The following provides a detailed description of the implementation methods of the first anti-misalignment structure 130 and the second anti-misalignment structure 230.

In some exemplary embodiments, the first anti-misalignment structure 130 includes a first protruding portion 131 located on the second side wall 112, and the second anti-misalignment structure 230 includes a first limiting slot 232 located on the sixth side wall 212, the first limiting slot 232 being adapted to the first protruding portion 131. In the closed state, the first protruding portion 131 is located inside the first limiting slot 232, such that the first anti-misalignment structure 130 and the second anti-misalignment structure 230 are engaged. In some exemplary embodiments, the first limiting slot is disposed on the second side wall 112, and the first protrusion is disposed on the sixth side wall 212.

Specifically, when the first protruding portion 131 is located inside the first limiting slot 232, along both directions perpendicular to the table-top, the first protruding portion 131 abuts against the slot wall of the first limiting slot 232, such that the first protruding portion 131 and the first limiting slot 232 are engaged. This can limit any relative displacement between any two of the first table-top 100, the second table-top 200, and the hinge 300 along both directions perpendicular to the table-top. The first rotation shaft 310, the second rotation shaft 320, and the abutting first protruding portion 131 and first limiting slot 232 can make the first table-top 100 and the second table-top 200 kept relatively fixed, thereby reducing the risk of misalignment of the first table-top 100 and the second table-top 200 in the direction perpendicular to the table-top.

When the first protruding portion 131 is disengaged from the first limiting slot 232, the first anti-misalignment structure 130 and the second anti-misalignment structure 230 are decoupled from each other, and any two of the first table-top 100, the second table-top 200, and the hinge 300 can move relative to each other in at least one direction perpendicular to the table-top, that is, the table-top can be folded.

Further, the first protruding portion 131 includes at least one first sub-protruding portion 1312, and the first limiting slot 232 includes at least one first sub-limiting slot 2321. In some exemplary embodiments, the at least one first sub-protruding portion 1312 is one, and the at least one first sub-limiting slot 2321 is also one. That is, the first protruding portion 131 is a single integral structure, and the first limiting slot 232 is also a single integral structure. In this case, the single first sub-protruding portion 1312 is adapted to the single first sub-limiting slot 2321, that is, the first protruding portion 131 is length-adapted to the first limiting slot 232. Along the extension direction of the second side wall 112, both ends of the first protruding portion 131 can respectively abut against both ends of the first limiting slot 232, so as to limit the relative movement between the first table-top 100 and the second table-top 200.

FIG. 6B shows a schematic diagram of the structure of the second and sixth side walls of the table provided according to some exemplary embodiments of this disclosure. In some exemplary embodiments, as shown in FIG. 6B, the at least one first sub-protruding portion 1312 includes a plurality of first sub-protruding portions 1312 spaced along the extension direction of the second side wall 112. The at least one first sub-limiting slot 2321 is a single first sub-limiting slot 2321. In this case, the multiple first sub-protruding portions 1312 are adapted to the single first sub-limiting slot 2321, that is, the multiple first sub-protruding portions 1312 are overall length-adapted to the first limiting slot 232. Along the extension direction of the second side wall 112, the outermost ends of the multiple first sub-protruding portions 1312 can respectively abut against the two ends of the first limiting slot 232, thereby limiting the relative movement between the first table-top 100 and the second table-top 200. It can be understood that the number of the first sub-protruding portions 1312 can be any number, for example, 2, 3, 4, 5, 6, and so on.

FIG. 6C shows a schematic diagram of the structure of the second and sixth side walls of the table provided according to some exemplary embodiments of this disclosure. In some exemplary embodiments, as shown in FIG. 6B, the at least one first sub-protruding portion 1312 includes a plurality of first sub-protruding portions 1312 spaced along the extension direction of the second side wall 112. The at least one first sub-limiting slot 2321 includes a plurality of first sub-limiting slots 2321 spaced along the extension direction of the sixth side wall 212. In this case, the multiple first sub-protruding portions 1312 are adapted to the multiple first sub-limiting slots 2321, that is, the multiple first sub-protruding portions 1312 and the multiple first sub-limiting slots 2321 are distributed one-to-one in number and length. That is, the number of first sub-protruding portions 1312 and first sub-limiting slots 2321 is the same. At the same time, the first sub-protruding portion 1312 and the corresponding first sub-limiting slot 2321 are length-adapted. Along the extension direction of the second side wall 112, the two ends of each first sub-protruding portion 1312 can respectively abut against the two ends of the first sub-limiting slot 2321 at the corresponding position, thereby limiting the relative movement between the first table-top 100 and the second table-top 200.

It can be understood that the number of first sub-protruding portions 1312 can be any number, for example, 2, 3, 4, 5, 6, and so on. The number of first sub-limiting slots 2321 can be any number, for example, 2, 3, 4, 5, 6, and so on. At the same time, the number of first sub-protruding portions 1312 is the same as the number of first sub-limiting slots 2321, that is, when the number of first sub-protruding portions 1312 is 2, the number of first sub-limiting slots 2321 is also 2, and so on.

In some exemplary embodiments, the first anti-misalignment structure 130 includes a first protruding portion 131 and a second limiting slot 132 located on the second side wall 112. The second anti-misalignment structure 230 includes a first limiting slot 232 and a second protruding portion 231 located on the sixth side wall 212, the first limiting slot 232 being adapted to the first protruding portion 131, and the second protruding portion 231 being adapted to the second limiting slot 132. In the closed state, the first protruding portion 131 is located inside the first limiting slot 232, and the second protruding portion 231 is located inside the second limiting slot 132, such that the first anti-misalignment structure 130 and the second anti-misalignment structure 230 are engaged. The first and second protruding portions can be the same.

In some exemplary embodiments, when the table-top is in a closed state and facing upwards, the upper side of the first protruding portion 131 abuts against the first limiting slot 232, and the lower side of the second protruding portion 231 abuts against the second limiting slot 132. Alternatively, when the table-top is facing upwards, the lower side of the first protruding portion 131 abuts against the first limiting slot 232, and the upper side of the second protruding portion 231 abuts against the second limiting slot 132. The first and second limiting slots may also be the same. In this way, when the first anti-misalignment structure 130 is coupled with the second anti-misalignment structure 230, it can restrict relative displacement of the first table-top 100 and the second table-top 200 along both directions perpendicular to the table-top. The first rotation shaft 310, the second rotation shaft 320, the abutting first protruding portion 131 and first limiting slot 232, and the abutting second protruding portion 231 and second limiting slot 132 enable the first table-top 100 and the second table-top 200 to be relatively fixed, thereby reducing the risk of misalignment of the first table-top 100 and the second table-top 200 in the direction perpendicular to the table-top.

In some exemplary embodiments, the first protruding portion 131 is located at a first target position on the second side wall 112, and the first limiting slot 232 is located at a second target position on the sixth side wall 212. The first target position corresponds to the second target position. The second limiting slot 132 is located at a third target position on the second side wall 112, and the second protruding portion 231 is located at a fourth target position on the sixth side wall 212. The third target position corresponds to the fourth target position.

The first protruding portion 131 includes at least one first sub-protruding portion 1312, and the first limiting slot 232 includes at least one first sub-limiting slot 2321. The second protruding portion 231 includes at least one second sub-protruding portion 2311, and the second limiting slot includes at least one second sub-limiting slot 1321. In some exemplary embodiments, the at least one first sub-protruding portion 1312 is one, and the at least one first sub-limiting slot 2321 is also one. That is, the first protruding portion 131 is a single integral structure, and the first limiting slot 232 is also a single integral structure. The at least one second sub-protruding portion 2311 is one, and the at least one second sub-limiting slot 1321 is also one. That is, the second protruding portion 231 is a single integral structure, and the second limiting slot 132 is also a single integral structure. In this case, the first protruding portion 131 is length-adapted to the first limiting slot 232, and the second protruding portion 231 is length-adapted to the second limiting slot 132. Along the extending direction of the second side wall 112, both ends of the first protruding portion 131 can abut against the two ends of the first limiting slot 232 respectively, and both ends of the second protruding portion 231 can abut against the two ends of the second limiting slot 132 respectively, to restrict the relative movement of the first table-top 100 and the second table-top 200.

In some exemplary embodiments, as shown in FIG. 6B, the at least one first sub-protruding portion 1312 includes multiple first sub-protruding portions 1312 spaced apart along the extending direction of the second side wall 112. The at least one first sub-limiting slot 2321 is one. The at least one second sub-protruding portion 2311 includes multiple second sub-protruding portions 2311 spaced apart along the extending direction of the sixth side wall 212. The at least one second sub-limiting slot 1321 is one. In this case, the multiple first sub-protruding portions 1312 are length-adapted as a whole to the first limiting slot 232. The multiple second sub-protruding portions 2311 are length-adapted as a whole to the second limiting slot 132. Along the extending direction of the second side wall 112, the outermost two ends of the multiple first sub-protruding portions 1312 can respectively abut against the two ends of the first limiting slot 232, and the outermost two ends of the multiple second sub-protruding portions 2311 can respectively abut against the two ends of the second limiting slot 132, thereby restricting the relative movement between the first table-top 100 and the second table-top 200. It can be understood that the number of the first sub-protruding portions 1312 can be any number, for example, 2, 3, 4, 5, 6, and so on. The number of the second sub-protruding portions 2311 can be any number, for example, 2, 3, 4, 5, 6, and so on. The number of first sub-protruding portions 1312 and second sub-protruding portions 2311 can be the same or different.

In some exemplary embodiments, as shown in FIG. 6C, the at least one first sub-protruding portion 1312 includes multiple first sub-protruding portions 1312 spaced apart along the extending direction of the second side wall 112. The at least one first sub-limiting slot 2321 includes multiple first sub-limiting slots 2321 spaced apart along the extending direction of the sixth side wall 212. The at least one second sub-protruding portion 2311 includes multiple second sub-protruding portions 2311 spaced apart along the extending direction of the sixth side wall 212. The at least one second sub-limiting slot 1321 includes multiple second sub-limiting slots 1321 spaced apart along the extending direction of the second side wall 112. In this case, the multiple first sub-protruding portions 1312 and the multiple first sub-limiting slots 2321 are distributed one-to-one in number and length. That is, the number of first sub-protruding portions 1312 and first sub-limiting slots 2321 is the same. At the corresponding positions, the lengths of the first sub-protruding portions 1312 and first sub-limiting slots 2321 are adapted. The multiple second sub-protruding portions 2311 and the multiple second sub-limiting slots 1321 are distributed one-to-one in number and length. That is, the number of second sub-protruding portions 2311 and second sub-limiting slots 1321 is the same. At the corresponding positions, the lengths of the second sub-protruding portions 2311 and second sub-limiting slots 1321 are adapted. Along the extending direction of the second side wall 112, both ends of each first sub-protruding portion 1312 can abut against the two ends of the first sub-limiting slot 2321 at the corresponding position, and both ends of each second sub-protruding portion 2311 can abut against the two ends of the second sub-limiting slot 1321 at the corresponding position, thereby restricting the relative movement between the first table-top 100 and the second table-top 200.

It can be understood that the number of first sub-protruding portions 1312 can be any number, for example, 2, 3, 4, 5, 6, and so on. The number of first sub-limiting slots 2321 can be any number, for example, 2, 3, 4, 5, 6, and so on. At the same time, the number of first sub-protruding portions 1312 and the number of first sub-limiting slots 2321 are the same; that is, when the number of first sub-protruding portions 1312 is 2, the number of first sub-limiting slots 2321 is also 2, and so on. The number of second sub-protruding portions 2311 can be any number, for example, 2, 3, 4, 5, 6, and so on. The number of second sub-limiting slots 1321 can be any number, for example, 2, 3, 4, 5, 6, and so on. At the same time, the number of second sub-protruding portions 2311 and the number of second sub-limiting slots 1321 are the same; that is, when the number of second sub-protruding portions 2311 is 2, the number of second sub-limiting slots 1321 is also 2, and so on. The number of first sub-protruding portions 1312 and the number of second sub-protruding portions 2311 can be the same or different.

In some exemplary embodiments, the first protruding portion 131 serves as a support leg of the table 001 when the table-top is folded, preventing the second side wall 112 and the sixth side wall 212 from contacting the ground. Furthermore, the second protruding portion 231 also serves as a support leg of the table 001 when the table-top is folded, preventing the second side wall 112 and the sixth side wall 212 from contacting the ground. After the table-top is folded, the table 001 can be placed upright on the ground, at which time the second side wall 112 and the sixth side wall 212 face the ground, and the first handle 103 and the second handle 203 can be located at the top of the table 001. The provision of the support legs helps the second side wall 112 and the sixth side wall 212 remain clean.

In some exemplary embodiments, along the extending direction of the second side wall 112, the first protruding portion 131 and the second protruding portion 231 can be arranged in a staggered manner. This is conducive to improving the support stability of the first protruding portion 131 and the second protruding portion 231 for the table 001, reduce the risk of misalignment between the first table-top 100 and the second table-top 200. If the first table-top 100 and the second table-top 200 are misaligned, excessive stress at the connection portions among the hinge 300, the first table-top 100, and the second table-top 200 will easily cause wear. Therefore, avoiding misalignment between the first table-top 100 and the second table-top 200 can reduce wear at the connection portions among the hinge 300, the first table-top 100, and the second table-top 200, which is beneficial to extending the service life of the table.

In some exemplary embodiments, both the first protruding portion 131 and the first limiting slot 232 include an arcuate coupling surface 1311 to facilitate coupling between the first protruding portion 131 and the first limiting slot 232. Furthermore, both the second protruding portion 231 and the second limiting slot 132 include an arcuate coupling surface 1311.

The arcuate coupling surface 1311 can guide the first protruding portion 131 into the first limiting slot 232, and can also reduce the risk of interference between the first protruding portion 131 and the sixth side wall 212 during the folding of the table-top.

In some exemplary embodiments, the coupling surface 1311 may be configured as one of the following four structures or a combination thereof: (1) a plane perpendicular to the tabletop; (2) an inclined surface forming an acute angle or an obtuse angle with the tabletop; (3) an arc surface; (4) a plane parallel to the tabletop. Moreover, the first protruding portion 131 structurally corresponds to the first limiting slot 232. The second limiting slot 132 and the second protruding portion 231 are provided with reference to the first protruding portion 131 and the first limiting slot 232.

Further, the coupling surface 1311 includes an arc surface and a planar surface. This can reduce the risk of misalignment between the first table-top 100 and the second table-top 200 when the table-tops are unfolded, and is also beneficial for the first table-top 100 and the second table-top 200 to be in full contact, thereby reducing the risk of gaps being formed.

In some exemplary embodiments, when the table-top is in a foldable state, the top of the first protruding portion 131 and the opening of the second limiting slot 132 face the sixth side wall 212, and the opening of the first limiting slot 232 and the top of the second protruding portion 231 face the second side wall 112. When the table-top is folded, the opening of the first limiting slot 232 and the top of the first protruding portion 131 face the same direction. Furthermore, when the table-top is in a foldable state, the second side wall 112 is parallel to the sixth side wall 212, and the second table-top 200 can rotate 180° relative to the first table-top 100 to complete the folding of the foldable table-top.

As shown in FIG. 1 to 6A, the table 001 further includes a hinge 300. The hinge 300 is made of a metal material, such as aluminum, stainless steel, steel (e.g., carbon steel or galvanized steel), brass, bronze, titanium alloy, zinc alloy, or aluminum alloy.

The first table-top 100 includes a first side wall 111 and a second side wall 112. The first side wall 111 and the second side wall 112 are connected, and at the abutting portion, there is at least one inwardly recessed “L” shaped first docking slot 115. The second table-top 200 includes a fifth side wall 211 and a sixth side wall 212. The fifth side wall 211 and the sixth side wall 212 are connected, and at the abutting portion, there is at least one inwardly recessed “L” shaped second docking slot 215. A portion of the hinge 300 is disposed in the first docking slot 115, and another portion is disposed in the second docking slot 215, thereby connecting the first table-top 100 with the second table-top 200. Furthermore, the first end 141 of the first table-top 100 and the third end 241 of the second table-top 200 can be connected through the hinge 300.

In some exemplary embodiments, the thickness of the first docking slot 115 is the same as the thickness of the first side wall 111 and the second side wall 112. The thickness of the second docking slot 215 is the same as the thickness of the fifth side wall 211 and the sixth side wall 212. This design with the same thickness can simplify the manufacturing process and reduce material removal or molding complexity.

In some exemplary embodiments, the first docking slot 115 has a reinforcing structure on its wall to enhance its resistance to mechanical damage. The second docking slot 215 also has a reinforcing structure on its wall to enhance its resistance to mechanical damage. The reinforcing structure can be provided in at least one of the following ways: the second docking slot 215 has reinforcing ribs on its wall; and the wall thickness of the second docking slot 215 is greater than the wall thickness of the sixth side wall 212 and the fifth side wall 211.

In some exemplary embodiments, the thickness of the first docking slot 115 is greater than the thickness of the first side wall 111 and the second side wall 112. Here, the thickness of the first side wall 111 and the second side wall 112 is the same. The first docking slot 115 is thickened so that its thickness is greater than that of the first side wall 111 and the second side wall 112. The thickness of the second docking slot 215 is greater than the thickness of the fifth side wall 211 and the sixth side wall 212. Here, the thickness of the fifth side wall 211 and the sixth side wall 212 is the same. The second docking slot 215 is thickened so that its thickness is greater than that of the fifth side wall 211 and the sixth side wall 212. This approach can enhance the mechanical strength of the first docking slot 115 and the second docking slot 215, allowing them to better withstand the stress concentration and dynamic load generated by the hinge 300 due to repeated folding of the table-top(s). It can be understood that the thickness of a wall refers to the perpendicular distance between the inner surface and the outer surface of a wall-like structure. Herein, the thickness of the side wall 110 of the first table-top 100 can be 2 mm, and the thickness of the side wall 210 of the second table-top 200 can be 2 mm; for example, the thickness of the first side wall 111 and the second side wall 112 is 2 mm, and the thickness of the fifth side wall 211 and the sixth side wall 212 is 2 mm. The thickness of the first docking slot 115 and the second docking slot 215 is greater than the thickness of the side walls 110 and 210, for example, the thickness of the first docking slot 115 and the second docking slot 215 is 2.5 mm. In some exemplary embodiments, the thickness of the side wall 110 or side wall 210 can be between 1 mm and 5 mm; for example, the thickness of side wall 110 or side wall 210 can be 1.1 mm, 1.5 mm, 1.8 mm, 2 mm, 2.2 mm, 2.5 mm, 2.8 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, or 5 mm. The thickness of the first docking slot 115 or the second docking slot 215 can be between 1.5 mm and 6 mm; for example, the thickness of the first docking slot 115 or the second docking slot 215 can be 1.5 mm, 1.8 mm, 1.9 mm, 2 mm, 2.2 mm, 2.5 mm, 2.8 mm, 3 mm, 3.5 mm, 4 mm, 5 mm, or 6 mm. It can be understood that the above thicknesses can be designed according to actual needs and are not described in detail herein.

In some exemplary embodiments, the number of the first docking slots 115 and the second docking slots 215 can each be two. The two first docking slots 115 are symmetrically distributed along the transverse centerline of the first table-top 100, respectively located at the two ends of the connection region between the first side wall 111 and the second side wall 112. Correspondingly, the two second docking slots 215 are symmetrically arranged along the transverse centerline of the second table-top 200, corresponding to the positions of the first docking slots 115. It can be understood that the number of the first docking slots 115 and the second docking slots 215 can be other numbers, such as 4, 6, and so on, which is not limiting herein.

Correspondingly, the number of hinges 300 is two. The two hinge 300 structures are symmetrical, respectively located at the two ends of the connection region between the first side wall 111 and the second side wall 112. One of the two hinges 300 is connected to the first side wall 111 and the fifth side wall 211, and the other of the two hinges 300 is connected to the third side wall 113 and the seventh side wall 213.

Furthermore, the first table-top 100 can be slidably connected to the second table-top 200 through the hinge 300. When the table-top is unfolded, the second table-top 200 slides relative to the first table-top 100, allowing the table-top to switch between the closed state and the foldable state. The first table-top 100 is rotatably connected to the hinge 300. The second table-top 200 is rotatably connected to the hinge 300. In the foldable state, the first table-top 100 and the second table-top 200 can fold around the hinge 300.

During the folding process of the table-top, the first table-top 100 and the second table-top 200 can respectively rotate relative to the hinge 300, so that the first table-top 100 and the second table-top 200 can rotate relative to each other to achieve folding of the table-top. In this way, the connection structure between the first table-top 100 and the second table-top 200 can have two rotational degrees of freedom, making the connection structure more flexible and the folding process of the table-top smoother.

In some exemplary embodiments, the hinge 300 includes a hinge bracket 330. The hinge bracket 330 is used to support and connect the various portions of the hinge 300. Furthermore, the hinge bracket 330 is a housing, which allows the hinge 300 to have a simple and aesthetically pleasing appearance. The housing includes a first wall 335 away from the second table-top 200 and a second wall 336 close to the second table-top 200.

In some exemplary embodiments, the first side wall 111 is rotatably connected to the hinge bracket 330, so that the first table-top 100 can rotate relative to the hinge 300 around a first axis. The fifth side wall 211 is rotatably connected to the hinge bracket 330, so that the second table-top 200 can rotate relative to the hinge 300 around a second axis.

In some exemplary embodiments, as shown in FIG. 1 to 4, when the table-top is unfolded: the extending direction D1 of the hinge bracket 330 is parallel to the table-top. When the table-top is folded: the extending direction D1 of the hinge bracket 330 is perpendicular to the table-top. Here, when the table-top is in use, it can face upwards. This is conducive to reducing the installation space of the hinge bracket 330 on the table 001 and also helps align the edges of the first table-top 100 and the second table-top 200 when the table-top is folded.

In some exemplary embodiments, as shown in FIG. 1 to 4, the outer peripheral sides of the first table-top 100 and the second table-top 200 form a notched portion 101, and the hinge 300 is located in the notched portion 101. This helps reduce the risk of accidental contact with the hinge bracket 330 and also contributes to the aesthetic appearance of the table 001.

Furthermore, the notched portion 101 can be partially located on the outer peripheral side of the first table-top 100 and partially on the outer peripheral side of the second table-top 200. As the first table-top 100, the hinge 300, and the second table-top 200 move relative to each other, the structure of the notched portion 101 also changes, thereby accommodating the hinge 300.

The number of notched portions 101 can be the same as the number of hinges 300. In some exemplary embodiments, the number of notched portions 101 is two. One of the two notched portions 101 is provided at the first side wall 111 and the fifth side wall 211, and the other of the two notched portions 101 is provided at the third side wall 113 and the seventh side wall 213.

FIG. 7 shows a schematic diagram of the connection structure of a table provided in some exemplary embodiments of this disclosure. FIG. 8 shows a stereoscopic schematic diagram of a hinge provided in some exemplary embodiments of this disclosure. FIG. 9 shows an exploded schematic diagram of a hinge provided in some exemplary embodiments of this disclosure. In some exemplary embodiments, as shown in FIG. 7 to 9, the table 001 further includes a first rotation shaft 310 and a second rotation shaft 320. The first table-top 100 is rotatably connected to the hinge 300 via the first rotation shaft 310. The second table-top 200 is rotatably connected to the hinge 300 via the second rotation shaft 320. Furthermore, the central axis of the first rotation shaft 310 and the central axis of the second rotation shaft 320 are spaced apart and parallel. Herein, when the table-top is in the foldable state or the table-top is being folded, the central axis of the first rotation shaft 310 can coincide with the first axis, and the central axis of the second rotation shaft 320 can coincide with the second axis.

In some exemplary embodiments, as shown in FIG. 4 to 9, the first end 311 of the first rotation shaft 310 is connected to the hinge bracket 330, and the second end 312 of the first rotation shaft 310 is connected to the side wall 110 of the first table-top 100, so that the first table-top 100 is rotatably connected to the hinge bracket 330 via the first rotation shaft 310. For example, the second end 312 of the first rotation shaft 310 is connected to the first side wall 111.

In some exemplary embodiments, as shown in FIG. 4 to 9, the first rotation shaft 310 includes a first positioning portion 313. The first positioning portion 313 is configured to restrict the hinge 300 and the first table-top 100 from separating from each other. The side wall 110 is provided with a shaft hole 120. For example, the first side wall 111 is provided with the shaft hole 120. The shaft hole 120 is adapted to the first rotation shaft 310, meaning the size and shape of the shaft hole 120 can allow the first rotation shaft 310 to pass through. The first rotation shaft 310 can be connected to the side wall 110 of the first table-top 100 through the shaft hole 120. For example, the first rotation shaft 310 passes through the first side wall 111 via the shaft hole 120, the first positioning portion 313 can abut against the inner side of the first side wall 111, and the second wall 336 can abut against the outer side of the first side wall 111, thereby restricting the hinge 300 and the first table-top 100 from separating from each other along the axial direction of the first rotation shaft 310. Furthermore, the first positioning portion 313 has a ring structure and is distributed around the central axis of the first rotation shaft 310.

The second rotation shaft 320 includes a second positioning portion 323. The second positioning portion 323 is configured to restrict the hinge 300 and the second table-top 200 from separating from each other. For example, the second rotation shaft 320 passes through the fifth side wall 211, the second positioning portion 323 can abut against the inner side of the fifth side wall 211, and the second wall 336 can abut against the outer side of the fifth side wall 211, thereby restricting the hinge 300 and the second table-top 200 from separating from each other along the axial direction of the second rotation shaft 320. Furthermore, the second positioning portion 323 has a ring structure and is distributed around the central axis of the second rotation shaft 320.

In some exemplary embodiments, as shown in FIG. 4 to 9, the first end 321 of the second rotation shaft 320 is connected to the hinge bracket 330. The side wall 210 of the second table-top 200 is provided with a slide groove 220. For example, the fifth side wall 211 is provided with the slide groove 220. The second end 322 of the second rotation shaft 320 is located within the slide groove 220 and is rotatable and slidable relative to the second table-top 200, so that the second table-top 200 is rotatably and slidably connected to the hinge bracket 330 via the second rotation shaft 320.

The slide groove 220 can be used to guide the sliding direction of the second table-top 200 relative to the first table-top 100, thereby guiding the table-top to switch between the closed state and the foldable state. Furthermore, the extending direction of the slide groove 220 can be parallel to the sliding direction of the second table-top 200 relative to the first table-top 100. In this way, the provision of the slide groove 220 helps improve the stability of the switching process of the table-top between the closed state and the foldable state.

In some exemplary embodiments, as shown in FIGS. 4 and 6A, the slide groove 220 includes a first section 221 and a second section 222. When the table-top is unfolded, the distance between the first section 221 and the first table-top 100 is greater than the distance between the second section 222 and the first table-top 100. In the closed state, the second rotation shaft 320 is located in the first section 221. In the foldable state, the second rotation shaft 320 is located in the second section 222.

Specifically, the second rotation shaft 320 can slide within the slide groove 220 along the extending direction of the slide groove 220. During the process of switching the table-top from the closed state to the foldable state, the second rotation shaft 320 slides from the first section 221 to the second section 222. During the process of switching the table-top from the foldable state to the closed state, the second rotation shaft 320 slides from the second section 222 to the first section 221.

In some exemplary embodiments, the first section 221 is located at the end of the slide groove 220 away from the first table-top 100, and the second section 222 is located at the end of the slide groove 220 near the first table-top 100. The sliding distance of the second table-top 200 relative to the first table-top 100 may be limited by the length of the slide groove 220, facilitating the user to control the spacing between the second table-top 200 and the first table-top 100 in the foldable state.

As shown in FIG. 5, the first table-top 100 further includes a first shim piece 140. With reference to FIGS. 5 to 9, the first side wall 111 and the second wall 336 are arranged opposite to each other, and the first shim piece 140 is located between the first side wall 111 and the second wall 336. Specifically, during use, the first shim piece 140 is installed on the outside of the first side wall 111, that is, the first shim piece 140 is installed on the side of the first side wall 111 facing the second wall 336. The first shim piece 140 includes a first hole 141. The first hole 141 corresponds to the shaft hole 120, that is, the size and shape of the first hole 141 are the same as those of the shaft hole 120. During use, the first hole 141 aligns with the shaft hole 120 so that the first rotation shaft 310 can pass through both the shaft hole 120 and the first hole 141 through the first side wall 111.

The second table-top 200 further includes a second shim piece 240. The fifth side wall 211 and the second wall 336 are arranged opposite to each other. The second shim piece 240 is located between the fifth side wall 211 and the second wall 336. During use, the second shim piece 240 is installed on the outside of the fifth side wall 211, that is, the second shim piece 240 is installed on the side of the fifth side wall 211 facing the second wall 336. The second shim piece 240 includes a second slot 241a. The second slot 241a corresponds to the slide groove 220, that is, the size and shape of the second slot 241a are the same as those of the slide groove 220. During use, the second slot 241a aligns with the slide groove 220 so that the second rotation shaft 320 can slide within the slide groove 220.

The first shim piece 140 and the second shim piece 240 are made of a metal material, for example, aluminum, stainless steel, steel (such as carbon steel or galvanized steel), brass, bronze, titanium alloy, zinc alloy, or aluminum alloy. In the case where the main body material of the table 001 is a plastic with relatively low hardness, adding metal first shim piece 140 and second shim piece 240 between the plastic side walls 110, 120 and the metal hinge 300 can effectively prevent direct contact and friction between metal and plastic. The metal shim pieces 140, 240 have higher hardness, stronger compressive resistance, and lower frictional wear, and can withstand the mechanical stress caused by long-term rotation or sliding of the rotation shaft 310, 320, thereby significantly reducing wear on the plastic side walls 110, 120. In addition, adding metal first shim piece 140 and second shim piece 240 between the plastic side walls 110, 120 and the metal hinge 300 can also prevent misalignment between the first table-top 100 and the second table-top 200 during folding, increase the connection pressure between the hinge 300 and the table-top, and extend the service life of the hinge 300.

In some exemplary embodiments, the hinge 300 includes a hinge bracket 330, a first rotation shaft 310, and a second rotation shaft 320. The hinge bracket 330, the first rotation shaft 310, and the second rotation shaft 320 can be assembled into a single module. For example, the hinge bracket 330, the first rotation shaft 310, and the second rotation shaft 320 can be connected by an integral molding method.

In some exemplary embodiments, the table 001 includes a second rotation shaft 320. A slide groove 220 is provided on the hinge bracket 330, and the first end 321 of the second rotation shaft 320 is located within the slide groove 220, being rotatable and slidable relative to the hinge bracket 330. The second end 322 of the second rotation shaft 320 is connected to the side wall 210 of the second table-top 200, so that the second table-top 200 is rotatably and slidably connected to the hinge bracket 330 through the second rotation shaft 320. In other words, the second rotation shaft 320 can slide together with the second table-top 200 along the extending direction of the slide groove 220 relative to the hinge bracket 330, allowing the table-top to switch between the closed state and the foldable state.

FIG. 10 illustrates a schematic view of a partial structure of a hinge provided in some exemplary embodiments of the present disclosure. In some exemplary embodiments, as shown in FIG. 8 to 9, a locking mechanism 340 is also provided on the hinge bracket 330. The locking mechanism 340 is configured to have a locked state and an unlocked state. In the unlocked state, the locking mechanism 340 allows the second table-top 200 to slide between a first position and a second position. When the table-top is in the closed state, the locking mechanism 340 can enter the locked state to lock the second table-top 200 in the first position.

That is, in the unlocked state, the locking mechanism 340 allows the table-top to switch between the closed state and the foldable state, and in the locked state, the locking mechanism 340 restricts the table-top from switching between the closed state and the foldable state. In this way, when the table-top is used in the closed state, the locking mechanism 340 can promote the stability of the structure of the table 001 and reduce the risk of uncontrolled changes in the structure of the table 001.

In some exemplary embodiments, as shown in FIG. 4 to 9, the second table-top 200 is provided with a limiting portion. The locking mechanism 340 includes a locking part. In the locked state, the locking part abuts against the limiting portion to restrict the second table-top 200 from sliding relative to the hinge bracket 330. In the unlocked state, the locking part disengages from the limiting portion to allow the second table-top 200 to slide relative to the hinge bracket 330.

In some exemplary embodiments, the locking portion is a protrusion, and the limiting portion is a slot, with the locking portion and the limiting portion being adapted in shape and size. The limiting portion may be part of the slide groove 220, or it may be spaced apart from the slide groove 220. In some exemplary embodiments, the limiting portion may also be a protrusion.

By controlling the switching of the locking part between the state of abutting the limiting portion and the state of disengaging from the limiting portion, the user can control the locking mechanism 340 to switch between the locked state and the unlocked state. In some exemplary embodiments, the user can manually drive the movement of the locking part, causing the locking part to switch between the state of abutting the limiting portion and the state of disengaging from the limiting portion. In some exemplary embodiments, the table 001 may include a motor. The locking part can be driven by the motor to move, thereby switching between the state of abutting the limiting portion and the state of disengaging from the limiting portion.

In some exemplary embodiments, as shown in FIG. 4 to 9, the locking part is a pin 342, the first end of which is rotatably connected to the hinge bracket 330 through a pin hole 331. The hinge bracket 330 includes a guiding wall 332 surrounding the pin hole 331, and the guiding wall 332 includes a helically extending guiding surface 333. The pin 342 includes a guiding portion 343, which is slidably connected to the guiding surface 333. When the pin 342 rotates, the guiding portion 343 slides along the guiding surface 333, thereby guiding the pin 342 to move linearly along the axis of the pin hole 331, causing the second end of the pin 342 to enter and exit the limiting portion, so that the locking mechanism 340 switches between the locked state and the unlocked state.

The guiding portion 343 can abut against the guiding surface 333. The guiding wall 332 and the hole wall of the pin hole 331 can guide the pin 342 to rotate and move linearly. With the helically extending guiding surface 333, when the pin 342 is driven to rotate relative to the hinge bracket 330, it can move linearly along the axis of the pin hole 331. When the pin 342 moves linearly into the limiting portion, the locking mechanism 340 switches from the unlocked state to the locked state. When the pin 342 moves linearly out of the limiting portion, the locking mechanism 340 switches from the locked state to the unlocked state.

In some exemplary embodiments, the guiding surface 333 faces the second table-top 200, and the guiding portion 343 is located on the side of the guiding surface 333 close to the second table-top 200. The guiding surface 333 can limit the guiding portion 343 by abutting against the guiding portion 343, thereby restricting the pin 342 from disengaging from the hinge bracket 330 in the direction away from the second table-top 200.

In some exemplary embodiments, the number of guiding portions 343 is two, and the two guiding portions 343 are symmetrically arranged on the pin 342.

In some exemplary embodiments, the first wall 335 and the guiding wall 332 form a guiding hole 337, and the pin 342 passes through the guiding hole 337. The axis of the guiding hole 337 is parallel to the axis of the pin 342.

In some exemplary embodiments, the guiding wall 332 can be replaced with a screw nut, and the pin 342 can be configured in the form of a screw. In some exemplary embodiments, the user can pull to make the pin 342 exit the limiting portion.

In some exemplary embodiments, the pin hole 331 is located in the second wall 336, and the second end of the pin 342 can extend out from the hinge bracket 330 through the pin hole 331.

In some exemplary embodiments, as shown in FIG. 4 to 9, the limiting portion 223 is the side wall at the end of the slide groove 220 close to the first table-top 100. When the pin 342 enters the slide groove 220, it can abut against the side wall at the end of the slide groove 220 close to the first table-top 100, thereby restricting the second table-top 200 from moving away from the first table-top 100, which causes the locking mechanism 340 to switch from the unlocked state to the locked state.

In some exemplary embodiments, the limiting portion is a limiting hole (not shown) on the side wall 210 of the second table-top 200. The limiting hole can be spaced apart from the slide groove 220. When the pin 342 enters the limiting hole, it can abut against the hole wall of the limiting hole, thereby restricting the second table-top 200 from moving away from the first table-top 100, which causes the locking mechanism 340 to switch from the unlocked state to the locked state.

In some exemplary embodiments, as shown in FIG. 4 to 9, the locking mechanism 340 further includes a first catch portion 334 and a second catch portion 344. The first catch portion 334 is at a preset position on the guiding wall 332. The second catch portion 344 is on the guiding portion 343, and the shape of the first catch portion 334 is adapted to the shape of the second catch portion 344. When the pin 342 rotates forward, the second catch portion 344 slides to the preset position to couple with the first catch portion 334, thereby locking the position of the pin 342. When the pin 342 rotates backward, the second catch portion 344 leaves the preset position and decouples from the first catch portion 334.

For example, the first catch portion 334 is a groove on the guiding surface 333, and the second catch portion 344 is a protrusion on the guiding portion 343. When the pin 342 rotates, after the second catch portion 344 slides to the preset position, it can enter the first catch portion 334, thereby locking the position of the pin 342.

In some exemplary embodiments, as shown in FIG. 8 to 9, the first end of the pin 342 further includes a knob 346. The knob 346 is located on the side of the hinge bracket 330 away from the second table-top 200. When the knob 346 rotates, it drives the pin 342 to rotate, thereby switching the locking mechanism 340 between the unlocked state and the locked state. The knob 346 can be located on the surface of the table 001, allowing the user to rotate the knob 346 to drive the pin 342 to rotate.

Furthermore, the knob 346 can be located on the outside of the first wall 335, that is, the portion of the first end of the pin 342 extending outward from the guiding hole 337 forms the knob 346.

In some exemplary embodiments, as shown in FIG. 8 to 9, the knob 346 further includes a foldable handle 3461. Before rotating the knob 346, the user can unfold the foldable handle 3461, thereby facilitating the user to apply force to the knob 346; for example, it can make it easier for users with manicured nails to rotate the knob 346.

In some exemplary embodiments, as shown in FIG. 8 to 10, the locking mechanism 340 includes an elastic member 347, which abuts between the second wall 336 and the first end of the pin 342. When the locking mechanism 340 is in the locked state, the elastic member 347 elastically deforms. During the recovery of the elastic deformation, the elastic member 347 drives the locking mechanism 340 to switch from the locked state to the unlocked state. When the guiding surface 333 weakly constrains the movement trajectory of the guiding portion 343, the provision of the elastic member 347 can keep the guiding portion 343 in abutment with the guiding surface 333, thereby facilitating the movement of the guiding portion 343 along the extending direction of the guiding surface 333.

Furthermore, the elastic member 347 is a spring.

FIG. 11 illustrates a schematic view of the back structure of the table provided in some exemplary embodiments of the present disclosure. As shown in FIG. 11, the table 001 further includes a wheel assembly 400. The wheel assembly 400 includes at least one wheel 420 and at least one mounting cavity 410. The at least one wheel 420 is set separately from the first table-top 100 and the second table-top 200 at the factory, facilitating packaging and transportation. The at least one wheel 420 can be pre-stored inside a drawer of the table 001 (for example, the first drawer 102 or the second drawer 202) and shipped together with the table 001, preventing loss or damage during transportation. After the table 001 is delivered to the user, the user can take out the at least one wheel 420 from the drawer and, according to the installation instructions, fix it to the back of the first table-top 100 and the second table-top 200.

Specifically, the back of the first table-top 100 and the second table-top 200 can be provided with at least one mounting cavity 410. The at least one wheel 420 can be installed in the at least one mounting cavity 410, ensuring stable installation and accurate positioning. The size and shape of the at least one mounting cavity 410 are the same as the size and shape of the installation base of the at least one wheel 420. The at least one wheel 420 can be installed in the at least one mounting cavity 410 by a fixed connection. The fixed connection can be at least one of an adhesive connection or a mechanical connection. The adhesive connection can be at least one of glue or double-sided tape. The mechanical connection can be at least one of a screw, a clip, or riveting. The number of the at least one wheel 420 corresponds to the number of the at least one mounting cavity 410, that is, there are as many mounting cavities 410 as there are wheels 420. The number of wheels 420 and mounting cavities 410 can be any number, for example, 2, 3, 4, 5, 6, 7, 8, etc., without limitation herein.

In some exemplary embodiments, the depth of the mounting cavity 410 ranges from 0.2 mm-0.5 mm, 0.5 mm-1 mm, 0.8 mm-1.5 mm, 1 mm-2 mm, 2 mm-5 mm, 5 mm-8 mm, or 8 mm-15 mm. The depth of the mounting cavity 410 is the distance between the bottom of the mounting cavity 410 and the opening of the mounting cavity 410.

In some exemplary embodiments, the table 001 includes at least one first wheel 421 and at least one second wheel 422. The at least one first wheel 421 is mounted on the back of the first table-top 100, and at least one second wheel 422 is mounted on the back of the second table-top 200. The number of first wheels 421 can be set according to actual needs, for example, 2, 3, 4, 5, 6, 7, 8, etc., and is not limited herein. The number of second wheels 422 can be set with reference to the number of the first wheels 421.

In some exemplary embodiments, the diameter of a single wheel 421, 422 is less than 10 cm. For example, the diameter of wheels 421, 422 ranges from 1 cm-3 cm, 2 cm-4 cm, 3 cm-5 cm, 5 cm-8 cm, or 8 cm-10 cm. This helps reduce the overall size of the table 001 and facilitates the arrangement of multiple wheels 421, 422.

In summary, first, the table 001 provided in the present disclosure has no gap or substantially no gap at the joint between the first table-top 100 and the second table-top 200 in the closed state, which can prevent objects such as puzzle pieces from falling into the gap. In the foldable state, there is a spacing between the first table-top 100 and the second table-top 200, which can reduce or eliminate mutual interference between the first table-top 100 and the second table-top 200 during the folding process, facilitating the user to fold the table-top, thereby configuring the table-top to switch between the closed state and the foldable state. Second, the table 001 is provided with the first shim piece 140 and the second shim piece 240 at the hinge bracket 330 and the connections with the first table-top 100 and the second table-top 200, avoiding direct contact between the first table-top 100 and the hinge bracket 330 and between the second table-top 200 and the hinge bracket 330, improving service life and stability. Third, the table 001 provided in the present disclosure increases the thickness of the first docking slot 115 and the second docking slot 215 at the hinge 300 installation, further enhancing service life and stability. Fourth, the table 001 provided in the present disclosure designs various structures of the first protruding portion 131 and the first limiting slot 232 to meet different scenarios and design requirements. Moreover, the table 001 provided in the present disclosure designs a drawer limiting structure for the first drawer 102 and the second drawer 202, preventing the first drawer 102 and the second drawer 202 from sliding out of the drawer openings. Finally, the table 001 provided in the present disclosure installs at least one wheel 420 on the back of the first table-top 100 and the second table-top 200, providing mobility for the table 001. These designs enrich the functions of the table 001 while improving the user's experience with the table 001.

Referring to FIG. 1 to FIG. 11, the present disclosure provides a table 001 with foldable table-tops. The table 001 includes a hinge 300, the first table-top 100, and the second table-top 200. The first table-top 100 is rotatably connected to the hinge 300. The first table-top 100 includes the second side wall 112, and the second side wall 112 is provided with the first anti-misalignment structure 130. The first anti-misalignment structure 130 includes at least one of the first protruding portion 131 and the second limiting slot 132. The second table-top 200 is rotatably connected to the hinge 300. The second table-top 200 includes the sixth side wall 212, and the sixth side wall 212 is provided with the second anti-misalignment structure 230. The second anti-misalignment structure 230 includes at least one of the second protruding portion 231 and the first limiting slot 232. The first anti-misalignment structure 130 structurally corresponds to the second anti-misalignment structure 230. When the table-tops are unfolded, they include a closed state. In the closed state, the second side wall 112 abuts against the sixth side wall 212, and the first anti-misalignment structure 130 is coupled with the second anti-misalignment structure 230 to limit relative displacement of the first table-top 100 and the second table-top 200 in both forward and backward directions perpendicular to the table-tops.

In some exemplary embodiments, the first table-top 100 is slidably connected to the second table-top 200 through the hinge 300. When the table-tops are unfolded, they include a closed state and a foldable state. In the closed state, the second table-top 200 slides to a first position relative to the first table-top 100, and the first table-top 100 and the second table-top 200 are closed together. In the foldable state, the second table-top 200 slides to a second position relative to the first table-top 100, and the first table-top 100 and the second table-top 200 are separated and foldable about the hinge 300.

In some exemplary embodiments, the table 001 further includes the first rotation shaft 310 and the second rotation shaft 320. The hinge 300 includes a hinge bracket 330. The first end 141 of the first rotation shaft 310 is connected to the hinge bracket 330, and the second end 142 is connected to the side wall 110 of the first table-top 100, so that the first table-top 100 is rotatably connected to the hinge bracket 330 through the first rotation shaft 310. The first end 141 of the second rotation shaft 320 is connected to the hinge bracket 330. The side wall 210 of the second table-top 200 is provided with a slide groove 220. The second end 142 of the second rotation shaft 320 is located in the slide groove 220 and is rotatable and slidable relative to the second table-top 200, so that the second table-top 200 is rotatably and slidably connected to the hinge bracket 330 through the second rotation shaft 320.

In summary, the connection structure between the first table-top 100 and the second table-top 200 has two rotational degrees of freedom, meaning that the first table-top 100 and the second table-top 200 rotate relative to each other about the first rotation shaft 310 and the second rotation shaft 320. This makes the connection structure between the first table-top 100 and the second table-top 200 more flexible. If the first anti-misalignment structure 130 and the second anti-misalignment structure 230 are not provided, the first table-top 100 and the second table-top 200 are prone to misalignment. “Misalignment” refers to the bearing surface of the first table-top 100 and the bearing surface of the second table-top 200 being non-coplanar. In the closed state, the first anti-misalignment structure 130 and the second anti-misalignment structure 230 enable the first table-top 100 and the second table-top 200 to be relatively fixed. Thus, the first table-top 100 and the second table-top 200 are less likely to become misaligned during use. For detailed embodiments of the table 001, please refer to the relevant descriptions in the preceding sections, which will not be repeated herein.

Referring to FIG. 1 to FIG. 11, the present disclosure provides a table 001 with foldable table-tops. The table 001 includes a hinge 300, the first table-top 100, the second table-top 200, at least one mounting cavity 410, and at least one wheel 420. The first table-top 100 is rotatably connected to the hinge 300. The second table-top 200 is rotatably connected to the hinge 300. At least one mounting cavity 410 is provided on the back surfaces of the first table-top 100 and the second table-top 200. At least one wheel 420 is mounted in the at least one mounting cavity 410 and is configured to provide a moving function for the table 001. In some exemplary embodiments, the mounting cavity 410 may be omitted, and at least one wheel 420 may be mounted directly on the back surfaces of the first table-top 100 and the second table-top 200.

If the wheel 420 is not provided, the table 001 will have a large friction force with the ground. A user would need to apply more force to move the table 001, making the table 001 prone to mechanical damage. Providing the wheel 420 facilitates movement of the table 001 and helps the table 001 maintain a good condition.

In some exemplary embodiments, the at least one wheel 420 includes at least one first wheel 421 and at least one second wheel 422, with the at least one first wheel 421 mounted on the back surface of the first table-top 100 and the at least one second wheel 422 mounted on the back surface of the second table-top 200.

In some exemplary embodiments, the first table-top 100 is slidably connected to the second table-top 200 through the hinge 300. When the table-tops are unfolded, they include a closed state and a foldable state. In the closed state, the second table-top 200 slides to a first position relative to the first table-top 100, and the first table-top 100 and the second table-top 200 are closed together. In the foldable state, the second table-top 200 slides to a second position relative to the first table-top 100, and the first table-top 100 and the second table-top 200 are separated and foldable about the hinge 300.

In some exemplary embodiments, the table 001 further includes the first rotation shaft 310 and the second rotation shaft 320. The hinge 300 includes a hinge bracket 330. The first end 141 of the first rotation shaft 310 is connected to the hinge bracket 330, and the second end 142 is connected to the side wall 110 of the first table-top 100, so that the first table-top 100 is rotatably connected to the hinge bracket 330 through the first rotation shaft 310. The first end 141 of the second rotation shaft 320 is connected to the hinge bracket 330. The side wall 210 of the second table-top 200 is provided with a slide groove 220. The second end 142 of the second rotation shaft 320 is located within the slide groove 220 and is rotatable and slidable relative to the second table-top 200, so that the second table-top 200 is rotatably and slidably connected to the hinge bracket 330 through the second rotation shaft 320.

In some exemplary embodiments, the first table-top 100 includes the second side wall 112, and the second side wall 112 is provided with the first anti-misalignment structure 130. The first anti-misalignment structure 130 includes at least one of the first protruding portion 131 and the first limiting slot 232. The second table-top 200 includes the sixth side wall 212, and the sixth side wall 212 is provided with the second anti-misalignment structure 230. The second anti-misalignment structure 230 includes at least one of the first protruding portion 131 and the first limiting slot 232. In the closed state, the second side wall 112 abuts against the sixth side wall 212, and the first anti-misalignment structure 130 couples with the second anti-misalignment structure 230 to limit relative displacement of the first table-top 100 and the second table-top 200 in both forward and backward directions perpendicular to the table-tops. For detailed embodiments of the table 001, please refer to the relevant descriptions in the preceding sections, which will not be repeated herein.

In summary, due to the presence of the wheel 420, the first table-top 100 and the second table-top 200 are spaced from the ground, where the ground refers to the surface that supports the table 001 in its usage scenario. If the first anti-misalignment structure 130 and the second anti-misalignment structure 230 are not provided, the first table-top 100 and the second table-top 200 are prone to misalignment. Here, “misalignment” refers to the bearing surface of the first table-top 100 and the bearing surface of the second table-top 200 being non-coplanar. In the closed state, the first anti-misalignment structure 130 and the second anti-misalignment structure 230 enable the first table-top 100 and the second table-top 200 to be relatively fixed. Thus, when the table 001 is in use and being moved, the first table-top 100 and the second table-top 200 are less likely to become misaligned. For detailed embodiments of the table 001, please refer to the relevant descriptions in the preceding sections, which will not be repeated herein.
