DETAILED DESCRIPTION

In the following, the solutions in the embodiments of the present disclosure are clearly and completely described with reference to the accompanying drawings. It should be noted that the described embodiments are merely a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by a person skilled in the art without involving any inventive effort are within the scope of the present disclosure.

In the description of the present application, it should be noted that the orientation or positional relationship indicated by terms such as “on”, “under”, “top”, “bottom”, “inside”, “outside” and the like, are based on the orientation or positional relationship shown in the drawings, which are merely for convenience of description of the present application and to simplify description, but not indicate or imply that the stated devices or members must have the particular orientation and be constructed and operated in a particular orientation, and thus these can not to be construed as limiting the present application. The term such as “a plurality of” means two or more, “at least one” means one, two or more than two, unless otherwise expressly specified. The terms “mounted”, “connected” and “connected to” should be understood in a broad sense. For example, it can be fixed connection, detachable connection or integrated connection. It can be directly connected or indirectly connected through an intermediate medium. It can be the internal communication of two devices or the interaction between two devices, unless there is a clear and specific limit. The terms “first”, “second” and the like are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature that are limited to “first” and “second” may explicitly or implicitly include one or more of the features.

In the description of the present application, the introduction of a first direction and a second direction is to more clearly describe the structure and the relative position relationship after mounting (laying) of the components in the surface covering assembly 10 in the embodiments of the present application. In the accompanying drawings of the present application, a first direction Z is indicated by an arrow labelled Z. Usually, the first direction Z is a thickness direction of the surface covering assembly 10. When the surface covering assembly 10 is laid on the ground, the first direction Z is a vertical direction. In the accompanying drawings of the present application, a second direction X is indicated by an arrow labelled X, and the second direction X is based on the first direction Z and perpendicular to the first direction Z. Specifically, when the surface covering assembly 10 is laid, the second direction X is an arrangement direction of an adjacent pair of first panel part 100 and second panel part 200. It can be understood that the second direction X of one adjacent pair of first panel part 100 and second panel part 200 can be different from the second direction X of another adjacent pair of first panel part 100 and second panel part 200.

As an introduction of the present application, at present, the main connection method for the floor is tongue-and-groove connection, that is, tongues and grooves of the panels are embedded into each other to realize the mutual locking connection between the panels. The stability of this connection method is poor, especially when the panels are expanded, the connection is easy to loose. In addition, there is another connection method of arranging embedded strips between the panels. In this method, an assembly grooves are formed in the middle of end faces opposite to each other of the panels. Before the panels are embedded in each other, the embedded strips are first placed in the assembly grooves, and then the panels are embedded in and combined with each other. This connection method increases the assembly difficulty, and after laying, the embedded strips are buried inside adjacent panels and can not be observed from the outside. When the panels needs to be replaced, due to the internal embedded strips, it is not easy to disconnect the adjacent panels, which may require destructive removal and affect secondary use.

In view of this, embodiments of the present application provide a surface covering assembly 10, and the surface covering assembly 10 can be used for covering and decorating surfaces such as floors or walls. For example, the surface covering assembly 10 is a portion of the floor, specifically, the surface covering assembly can be a composite structural unit for laying the floor. By laying multiple surface covering assemblies 10 to achieve overall coverage, decoration, and protection of the ground, the laying of the floor is completed. In the surface covering assembly 10, a force between the panels (first panel part 100 and second panel part 200) in the first direction Z is locked by a locking structure (locking part 300), and a force in the second direction X is locked by an interaction between the panels, so that they work together to achieve connection. As such, on the one hand, it can improve the stability of the connection, and on the other hand, it can also enhance the user experience.

Please refer to FIG. 1. The surface covering assembly 10 provided in embodiments of the present application includes a first panel part 100, a second panel part 200, and a locking part 300. The first panel part 100 and the second panel part 200 are panel structures of the surface covering assembly 10, which are used to connect with each other to cover and decorate the ground or other surfaces to be covered. The locking part 300 is used to lock the first panel part 100 and the second panel part 200, so that the first panel part 100 and the second panel part 200 can be stably connected to each other.

It should be noted that the surface covering assembly 10 includes an unassembled state and an assembled state. The unassembled state refers to a state where the surface covering assembly 10 is not mounted on a surface to be covered. In the unassembled state, the first panel part 100, the second panel part 200, and the locking part 300 are not assembled and connected to each other. The first panel part 100, the second panel part 200, and the locking part 300 need to be mounted and laid. The assembled state refers to a state where the surface covering assembly 10 is mounted on the surface to be covered. In the assembled state, the first panel part 100, the second panel part 200, and the locking part 300 are assembled and connected to each other. It can be understood that the surface covering assembly 10 can be in the assembled state or can be in the unassembled state. In order to facilitate the description of the structure and assembly relationship of each component in the surface covering assembly 10, the following mainly describes the assembled state.

Please refer to FIG. 1 to FIG. 4 together. The first panel part 100 includes a first edge portion 110, and the second panel part 200 includes a second edge portion 210. The first edge portion 110, the second edge portion 210, and the locking part 300 cooperate with each other to mount the first panel part 100 on at least one side of the second panel part 200 and to mount the second panel part 200 on at least one side of the first panel part 100. The first edge portion 110 is an assembly structure arranged on at least one side edge of the first panel part 100, and the second edge portion 210 is an assembly structure arranged on at least one side edge of the second panel part 200. Optionally, the first panel part 100 and the second panel part 200 are both of an integrated structure, which can be integrally processed and molded separately. After molded, the at least one side edge of the first panel part 100 is the first edge portion 110, and the at least one side edge of the second panel part 200 is the second edge portion 210.

Specifically, please refer to FIG. 12. A limiting groove 120 is arranged on a side of the first edge portion 110 in first direction Z. The limiting groove 120 is a groove formed by a depression from one side of the first edge portion 110 to another side of the first edge portion along the first direction Z. The second edge portion 210 includes a limiting structure 211. In the assembled state, the limiting structure 211 is arranged on a side of the first edge portion 110 in the first direction Z, and is partially located in the limiting groove 120. Thus, a part of the structure of the second edge portion 210 is embedded in the limiting groove 120 to limit the first edge portion 110 in the second direction X. Through a cooperation between the limiting structure 211 and the limiting groove 120, a mutual limitation between the first edge portion 110 and the second edge portion 210 in the second direction X can be realized, so that the first panel part 100 and the second panel part 200 are locked to each other in the second direction X. In the second direction X, a force is applied to the first panel part 100 and the second panel part 200 respectively. Due to a mutual cooperation between the limiting structure 211 and the limiting groove 120, the first panel part 100 and the second panel part 200 can be locked to each other and would not be easily separated.

Please refer to FIG. 13. A slot 400 is formed between the second edge portion 210 and the first edge portion 110, and a first end face of the first edge portion 110 and a second end face of the second edge portion 210 are enclosed to form the slot. The first end face is a face, facing toward the second edge portion 210, of the first edge, and the second end face is a face, opposite to the first end face, of the second edge portion 210. The slot 400 is located on a side, away from the limiting structure 211, of the first edge portion 110, and a slot opening 410 is formed on a side away from the limiting structure 211. That is, a part of the structure of the first edge portion 110 is located between the slot 400 and the limiting structure 211. Please refer to FIG. 3, FIG. 4 and FIG. 13 together. A part of the structure of the first edge portion 110 is located below the slot 400, the limiting structure 211 is located below the part of the structure of the first edge portion 110, the slot opening 410 of the slot 400 is formed on a side facing away from the limiting structure 211. And a bottom of slot 400 can be formed by a combination of the first edge portion 110 and the second edge portion 210 (FIG. 3), or it can also be formed by a part of the structure of the first edge portion 110 (FIG. 4).

Please refer to FIG. 1, FIG. 2, FIG. 3 and FIG. 4 together. The locking part 300 can be embedded in the slot 400 and exposed from the slot opening 410. The locking part 300 abuts against the first edge portion 110 and the second edge portion 210 to press the first edge portion 110 against the limiting structure 211. In a direction perpendicular to the first direction Z and the second direction X, the locking part 300 and the slot 400 are generally in a shape of a long strip. The locking part 300 is embedded in the slot 400. From the slot opening 410 of the slot 400, a part of the structure of the locking part 300 exposed from the slot opening 410 can be observed. Therefore, a gap formed by the slot 400 between the first panel part 100 and the second panel part 200 can be filled with locking part 300 for grouting, thus it is especially suitable for floor products with stone-like texture, enhancing the user experience.

It can be understood that through forming a limiting groove 120 on a side of the first edge portion 110 along the first direction Z, in the assembled state, the limiting structure 211 of the second edge portion 210 is arranged on a side of the first edge portion 110 along the first direction Z, and a part of the limiting structure 211 is embedded in the limiting groove 120. Thus, through a cooperation between the limiting structure 211 and the limiting groove 120, a mutual limitation between the first edge portion 110 and the second edge portion 210 in the second direction X can be realized, and a mutual locking between the first panel part 100 and the second panel part 200 in the second direction X can be realized. Through embedding the locking part 300 into the slot 400 enclosed by the first edge portion 110 and the second edge portion 210, the locking part 300 can abut against the first edge portion 110 and the second edge portion 210 to apply pressure to the first edge portion 110 and the second edge portion 210, so that the first edge portion 110 is pressed against the limiting structure 211, thereby realizing a locking between the first panel part 100 and the second panel part 200 in the first direction Z, and ensuring the stability of the connection. Through embedding the locking part 300 in the slot 400 and arranging the locking part to be exposed from the slot opening 410 of the slot 400, the gap formed by the slot 400 between the first panel part 100 and the second panel part 200 can be filled with the locking part 300 for filling and grouting. It is also convenient to disassemble the locking part 300 from the slot opening 410 to facilitate disassembly and replacement of the first panel part 100 and/or the second panel part 200, enhancing the user experience.

Please refer to FIG. 5, FIG. 6 and FIG. 7 together. In some embodiments, support portions 320 are arranged on two sides of the locking part 300, a support portion 320 located on one side is configured to abut against the first edge portion 110, and a support portion 320 located on another side is configured to abut against the second edge portion 210. Specifically, in the assembled state, the support portions 320 are arranged on two sides of the locking part 300 in the second direction X, and the support portions 320 are configured to protrude towards two sides of the locking part 300, so as to abut against the first edge portion 110 and the second edge portion 210 respectively, and the support portions 320 apply a force to the first edge portion 110 and the second edge portion 210. Therefore, on the one hand, the force applied to the first edge portion 110 and the second edge portion 210 on the second direction X is locked, and on the other hand, the first edge portion 110 can be more stably pressed against the limiting structure 211 to ensure the stability of an overall structure.

In some embodiments, avoidance grooves 360 are formed in the locking part 300, and the avoidance grooves 360 are located between the support portions 320 on two sides. The support portions 320 are configured to be compressed by the first edge portion 110 and the second edge portion 210 so as to be elastically deformed towards interior of the avoidance grooves 360. Through arranging the avoidance grooves 360 in the locking part 300 and arranging the avoidance grooves 360 between the support portions 320, an elastic performance of the locking part 300 can be improved, allowing for deformation of the support portions 320 when compressed. Therefore, on the one hand, it can reduce the mounting difficulty of the locking part 300, and an elastic deformation of the support portions 320 towards interior of the avoidance grooves 360 can be convenient to mount the locking part 300 into the slot 400 from the slot opening 410, and on the other hand, it can improve the elastic support performance of the support portions 320, so that the support portion can more stably abut against the first edge portion 110 and the second edge portion 210, so as to apply a more stable force to the first edge portion 110 and the second edge portion 210, and ensure the stability of the connection between the first panel part 100 and the second panel part 200.

Optionally, the locking part 300 includes a base portion 310, and the support portions 320 are connected to two sides of the base portion 310 to form an integrated structure with the base portion 310. Please refer to FIG. 5 again. The support portions 320 and the base portion 310 are enclosed to form avoidance grooves 360, and the avoidance grooves 360 are located between the support portions 320 and the base portion 310. Therefore, the avoidance grooves 360 are located inside the support portions 320. When the support portions 320 are compressed by the first edge portion 110 and the second edge portion 210, the support portions can be elastically deformed towards interior of the avoidance grooves 360.

Optionally, please refer to FIG. 7 again. The avoidance groove 360 is formed in a middle area of the locking part 300, that is, the avoidance groove 360 can be formed in the base portion 310. This arrangement also ensures that the avoidance groove 360 is located on inner sides of the support portions 320. When the support portions 320 are compressed by the first edge portion 110 and the second edge portion 210, the support portions can also be elastically deformed towards interior of the avoidance groove 360.

Please refer to FIG. 3, FIG. 4 and FIG. 8 together. In some embodiments, the first edge portion 110 includes a first boss 111, the second edge portion 210 includes a second boss 212 arranged opposite to the first boss 111 in the second direction X, and the slot opening 410 is arranged between the first boss 111 and the second boss 212. The first boss 111 is configured to be pressed against the support portion 320 on one side, and the second boss 212 is configured to be pressed against the support portion 320 on another side to limit the locking part 300 in the slot 400. In the assembled state, the first boss 111 and the second boss 212 are arranged opposite to each other. When the locking part 300 is embedded into the slot 400, the first boss 111 and the second boss 212 can be used for limitation above the support portions 320 on two sides respectively to limit the locking part 30 within the slot 400, so that the locking part would not be compressed out from the slot opening 410 by the first panel part 100 and the second panel part 200, thereby maintaining the stability of the connection between the first panel part 100 and the second panel part 200. In addition, since the first boss 111 and the second boss 212 are pressed against a corresponding support portion 320 respectively, and the support portions 320 is subjected to a downward pressure, the first edge portion 110 can be further tightly pressed against the limiting structure 211 of the second edge portion 210, and the locking effect between the first panel part 100 and the second panel part 200 in the first direction Z is enhanced.

Please refer to FIG. 2 to FIG. 8 together. In some embodiments, the locking part 300 further includes a sealing portion 330, and the sealing portion 330 is connected to the base portion 310 of the locking part 300. The sealing portion 330 is configured to abut between the first boss 111 and the second boss 212, and seal the slot opening 410. The slot opening 410 can be sealed with the sealing portion 330, so that external dust, liquids, and other dirt can be prevented from entering the slot 400, reducing the intrusion of dirt into the gap between the first panel part 100 and the second panel part 200. In addition, the slot 400 can be decorated with the sealing portion 330, that is, the gap between the first panel part 100 and the second panel part 200 can be decorated, so as to enhance the use experience. In particular, the surface covering assembly can be used for stone-like texture floors, and the sealing portion 330 of the locking part 300 can be used as grout between the panels, so as to improve the aesthetics and enhance the laying effect.

Specifically, the sealing portion 330 can be arranged above the base portion 310 and the support portions 320. The base portion 310, the support portions 320 on two sides of the base portion 310, and the sealing portion 330 above the base portion 310 are connected into an integrated structure. In the assembled state, the support portions 320 abut against the first edge portion 110 and the second edge portion 210 respectively, and are located below the first boss 111 and the second boss 212. The sealing portion 330 is arranged between the first boss 111 and the second boss 212, and is connected to the first boss 111 and the second boss 212, which is also good for maintaining the sealing of the gap between the first panel part 100 and the second panel part 200.

Please refer to FIG. 3 to FIG. 5 again. In some embodiments, the support portions 320 are connected to two sides of the base portion 310 and enclosed with the base portion 310 to form avoidance grooves 360. Buffer portions 340 are arranged on two sides of the sealing portion 330. The buffer sections 340 extend from the sealing portion 330 to interior of the avoidance grooves 360. The buffer portions 340 and the support portions 320 are arranged at intervals. The support portions 320 are configured to be compressed by the first boss 111 and the second boss 212 so as to be elastically deformed towards the buffer portions 340 and be in contact with the buffer portions 340. By arranging buffer portions 340 extending towards interior of the avoidance grooves 360 on two sides of the sealing portion 330, on the one hand, the sealing portion 330 can be strengthened by the buffer portions 340, and the structural strength of the sealing portion 330 can be improved, thereby improving the sealing effect, and on the other hand, when the support portions 320 are elastically deformed towards interior of the avoidance grooves 360, the support portions can be in contact with the buffer portions 340, and the buffer portions 340 can buffer the deformation of the support portions 320, reducing the occurrence of insufficient rebound of the support portions 320 caused by excessive deformation, and ensuring the support effect of the support portions 320.

In some embodiments, the buffer portions 340 and the base portion 310 are arranged at intervals, and the buffer portions 340 are configured to be compressed by the support portions 320 so as to be elastically deformed towards the base portion 310. Therefore, the buffering effect is improved, especially when the locking part 300 is embedded in the slot 400 from the slot opening 410, the gap between the buffer portions 340 and the base portion 310 can ensure that the support portions 320 are compressed by the first boss 111 and the second boss 212 to undergo sufficient deformation, so as to be embedded in the slot 400 smoothly. Meanwhile, it can also improve the elastic performance of the buffer portions 340. The reverse force applied by the buffer portions 340 on the support portions 320 is used to assist the support portions 320 in rebounding and recovering well, and fully ensuring the support effect of the support portions 320 on the first edge portion 110 and the second edge portion 210 on two sides. The stability of the connection between the first panel part 100 and the second panel part 200 is further guaranteed.

Please refer to FIG. 9 and FIG. 10 together. In the second direction X, the slot 400 has a first size L1, a second size L2 is formed between the first boss 111 and the second boss 212, a third size L3 is formed between the support portions 320 on two sides of the locking part 300, and the sealing portion 330 has a fourth size L4, which satisfy: L2≤L4≤L1≤L3. The first size L1 is a size of a distance between contact portions of the first edge portion 110 and the second edge portion 210 with the support portions 320 in the assembled state. The second size L2 is a size of a distance between contact portions of the first boss 111 and the second boss 212 with the sealing portion 330 in the assembled state. The third size L3 is a size of a distance between contact portions of the support portions 320 on two sides of the locking part 300 with the first edge portion 110 and the second edge portion 210 in the unassembled state. The fourth dimension L4 is a size of a distance between the sealing portion 330 with contact portions of the first boss 111 and the second boss 212 in the unassembled state. The above four sizes can be measured by conventional size measurement methods such as vernier calipers and micrometers. The above four sizes are set to satisfy L2≤L4≤L1≤L3, so that when the surface covering assembly 10 is in the assembled state, the locking part 300 is in a slightly compressed state, which can be stuck in the slot 400 and pressed against the first edge portion 110 and the second edge portion 210, so as to improve the stability of the overall structure.

In some embodiments, the locking part 300 is made of an elastic material, in which the elastic material refers to a material that can undergo reversible deformation after being subjected to force and can return to its original shape and size after removing the external force. For example, the locking part 300 can be made of rubber, silica gel, TPE (Thermoplastic Elastomer), and other materials, or can be made of metal materials with elastic deformation ability such as aluminum alloy.

Please refer to FIG. 3 to FIG. 5. In some embodiments, the locking part 300 includes an upper surface 350, the upper surface 350 is configured to be exposed to the slot opening 410, and the upper surface 350 is configured as a concave surface. Through configuring the upper surface 350 of the locking part 300 as a concave surface, dirt falling on the locking part 300 can be collected to the concave area, reducing the possibility of entering the slot 400 from two sides of the upper surface. In addition, configuring the upper surface 350 as a concave surface can improve the aesthetics after the gap between the first panel part 100 and the second panel part 200 being filled, enhancing the user experience.

Combining FIG. 3 and FIG. 7, in some embodiments, the locking part 300 further includes a lower surface 370, a part of the lower surface 370 is pressed against the first edge portion 110, and another part of the lower surface is pressed against the second edge portion 210. As such, it can make the assembly of the first panel part 100, the second panel part 200, and the locking part 300 more stable.

Please refer to FIG. 11, FIG. 12 and FIG. 13. In some embodiments, the second edge portion 210 includes a body 213, and the body 213 is configured to be enclosed with the first edge portion 110 to form the slot 400. That is, the body 213 is a part of the structure of the second edge portion 210 for enclosing with the first edge portion 110 to form the slot 400, and the limiting structure 211 is connected to a side, close to the first panel part 100, of the body 213. The limiting structure 211 includes a connecting block 2111 and a limiting block 2112. The connecting block 2111 is connected to the body 213 and extends from the body 213 in the second direction X. The connecting block 2111 is configured to clamp a part of the first edge portion 110 in the first direction Z with the locking part 300. That is, in the assembled state, in the first direction Z, at least a part of the first edge portion 110 is located between the locking part 300 and the connecting block 2111, and the locking part 300 applies pressure on the part of the first edge portion 110 to press it against the connecting block 2111. The limiting block 2112 is connected to a side, away from the body 213, of the connecting block 2111. The limiting block 2112 is embedded in the limiting groove 120. The limiting block 2112 is configured to clamp a part of the first edge portion 110 on the second direction X with the locking part 300. That is, in the assembled state, in the second direction X, at least a part of the first edge portion 110 is located between the limiting block 2112 and the locking part 300, and the locking part 300 applies pressure to the part of the first edge portion 110 and presses it against the limiting block 2112.

By arranging the connecting block 2111 and arranging it on a side, away from the locking part 300, of the first edge portion 110 in the first direction Z, the first edge portion 110 can be pressed against the connecting block 2111 through the locking part 300 to realize the locking between the first panel part 100 and the second panel part 200 in the first direction Z. By arranging the limiting block 2112 on a side, away from the body 213, of the connecting block 2111, the mutual locking between the first panel part 100 and the second panel part 200 in the second direction X can be realized through a cooperation between the limiting block 2112 and the limiting groove 120 arranged in the first edge portion 110.

Please combine FIG. 11 and FIG. 13 with FIG. 14. In some embodiments, the limiting block 2112 includes a first limiting face 2113, and the first limiting face 2113 is located on a side, close to the body 213, of the limiting block 2112. The first limiting face 2113 is attached to a first side wall 121 of the limiting groove 120, and an angle α between the first limiting face 2113 and the second direction X satisfies: α≤90°. By controlling the angle α within 90°, the force applied by the first limiting face 2113 on the first edge portion 110 is all or partially along the second direction X, which can make the limitation of the first edge portion 110 more stable and improve the stability of the locking between the first panel part 100 and the second panel part 200 in the second direction X. In particular, when the angle α<90°, a part of the force applied by the first limiting face 2113 on the first edge portion 110 is directed towards the connecting block 2111, which can produce a small amount of pressure on the first edge portion 110 towards the connecting block 2111, and improve the stability of the connection between the first panel part 100 and the second panel part 200 in the first direction Z. Optionally, the angle α can be of any value such as 90°, 85°, 80°, 75°, 70°, 65°, 60°, or a range between any two values.

In some embodiments, the body 213 includes an assembly face 2131, the assembly face 2131 is connected to a side, away from the limiting block 2112, of the connecting block 2111, and an angle β between the assembly face 2131 and the second direction X satisfies: β≤α. Specifically, the assembly face 2131 is a face, opposite to the first limiting face 2113, of the body 213. The angle β between the assembly face 2131 and the second direction X is configured as β≤α, so that the first edge portion 110 can be more easily embedded into the assembly groove 220 between the assembly face 2131 and the first limiting face 2113. Please combine FIG. 11 with FIG. 14. When β<α, the angle β of the assembly face 2131 is smaller than the angle α of the first limiting face 2113, that is, the assembly face 2131 is more inclined than the first limiting face 2113, which makes an opening of the assembly groove 220 on the side of the assembly face 2131 larger, so that the first edge portion 110 is easier to be mounted into the assembly groove 220. As shown in FIG. 15, the second panel part 200 can be laid on a surface to be covered, and the first panel part 100 can be parallel to the surface to be covered, and vertically placed into the assembly groove 220 along a direction shown by an arrow between the first panel part 100 and the second panel part 200. The assembly of the first panel part 100 and the second panel part 200 can be completed by slightly translating and adjusting the first panel part shift to the left based on the angle α. As such, the mounting difficulty of the surface covering assembly 10 can be greatly reduced and the mounting efficiency can be improved.

Please refer to FIG. 11 to FIG. 15 again. In some embodiments, the assembly face 2131, the connecting block 2111, and the first limiting face 2113 are enclosed to form the assembly groove 220, and the first edge portion 110 can be partially arranged in the assembly groove 220. In the first direction Z, the slot 400 is located above the assembly groove 220. In the second direction X, the slot 400 is at least partially located on a side, away from the limiting groove 120, of the assembly groove 220. As such, in the assembled state, the locking part 300 can more stably press the first edge portion 110 against the second edge portion 210 to maintain the mounting stability of the surface covering assembly 10.

Please refer to FIG. 12, FIG. 13, and FIG. 14 together. In some embodiments, the limiting block 2112 includes a second limiting face 2114, the second limiting face 2114 and the first limiting face 2113 are arranged facing away from each other, the second limiting face 2114 is attached to a second side wall 122 of the limiting groove 120, the second side wall 122 is arranged opposite to the first side wall 121, and the second limiting face 2114 is configured as an arc-shaped face. The second limiting face 2114 is configured as an arc-shaped face. On the one hand, it can increase the structural strength of the limiting block 2112 and improve the service life of the surface covering assembly 10, and on the other hand, it can reduce the assembly difficulty of the first panel part 100 and the second panel part 200, and improve the mounting efficiency.

Please refer to FIG. 16, FIG. 17, and FIG. 18 together. In some embodiments, the first panel part 100 and the second panel part 200 are of a same structure and both include the first edge portion 110 and the second edge portion 210. The first edge portion 110 and the second edge portion 210 are arranged facing away from each other. As such, the surface covering assembly 10 can be mounted only through a cooperation between the same panel structure and the locking part 30, which reduces the number of parts specifications, and further reduces the assembly difficulty. Moreover, the reduction in parts specifications further reduces the processing difficulty and reduces packaging costs.

Specifically, please refer to FIG. 19. In some embodiments, a main part of the panels is generally in a shape of a rectangle with four sides. Among every two opposite sides, the first edge portion 110 is arranged on one side, and the second edge portion 210 is arranged on the other side, which can meet the needs of large-area surface laying.

Please refer to FIG. 20 to FIG. 23 together. In some embodiments, the first panel part 100 includes a first side 101 and a second side 102 facing away from each other, and both the first side 101 and the second side 102 include the first edge portion 110. The second panel part 200 includes a third side 201 and a fourth side 202 facing away from each other, and both the third side 201 and the fourth side 202 include the second edge portion 210. As such, the surface can also be covered by alternately arranging the first panel part 100 and the second panel part 200 and embedding the locking part 300 in the slot 400 between adjacent first panel part 100 and second panel part 200.

Correspondingly, referring to FIG. 24, the embodiments of the present application further provide a floor 1, and the floor 1 can include at least one surface covering assembly 10 of any of the embodiments described above, so the floor 1 can have all the technical features and technical effects of the surface covering assembly 10 as described above, which will not repeated here. It should be noted that the floor 1 can be made of solid wood flooring, composite flooring, solid wood composite flooring, laminated flooring, PVC (polyvinyl chloride), and other materials. The floor 1 can include multiple surface covering assemblies 10, and the specific number of the surface covering assemblies can be determined based on the actual ground area needs to be laid and an area that a single surface covering assembly 10 can cover. An area of a single surface covering assembly 10 can be an area of the structure obtained by assembling a first panel part 100 and a second panel part 200 through a locking part 300.

A surface covering assembly according to the embodiments of the present application includes: at least one first panel part including a first edge portion, in which a limiting groove is formed in a side of the first edge portion in a first direction; at least one second panel part configured to be mounted on a side, where the first edge portion is located, of the first panel part, in which the second panel part includes a second edge portion, the second edge portion includes a limiting structure, the limiting structure is arranged on a side of the first edge portion in the first direction, partially located in the limiting groove to limit the first edge portion in a second direction, and the second direction is perpendicular to the first direction; and the second edge portion and the first edge portion are enclosed to form a slot, the slot is located on a side, away from the limiting structure, of the first edge portion, and a slot opening is formed in the side away from the limiting structure; and at least one locking part configured to be embedded in the slot and exposed from the slot opening, in which the locking part abuts against the first edge portion and the second edge portion to press the first edge portion against the limiting structure. In the embodiments of the present application, a connection between the first panel part and the second panel part can be realized by matching the first edge portion, the second edge portion, and the locking part, so as to realize a laying of the surface covering assembly. Specifically, by forming a limiting groove on a side of the first edge along the first direction, the limiting structure of the second edge portion can be arranged on a side of the first edge in the first direction during assembly, and the limiting structure is partially embedded in the limiting groove. Through a cooperation between the limiting structure and the limiting groove, the mutual limitation between the first edge portion and the second edge portion in the second direction is achieved, so as to realize locking between the first panel part and the second panel part in the second direction. By embedding the locking part into the slot enclosed by the first edge portion and the second edge portion, the locking part can abut against the first edge portion and the second edge portion, so as to press the first edge portion against the limiting structure, thus realizing the locking of the first panel part and the second panel part in the first direction, and ensuring the stability of the connection. By embedding the locking part in the slot and configuring the locking part exposed from the slot opening of the slot, a gap formed by the slot between the first panel part and the second panel part can be filled with the locking part for filling and grouting, and is also convenient to remove the locking part from the slot, so as to facilitate the removal and replacement of the first panel part and/or the second panel part, and improve the user experience.
