Description

CROSS-REFERENCE TO RELATED APPLICATIONS

The application a continuation in part of U.S. application Ser. No. 18/431,497, filed on Feb. 2, 2024, and claims priority of Chinese patent application CN2025225077646, filed on Nov. 25, 2025, disclosure of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the field of building blocks, in particular to a magnetic building block.

BACKGROUND

As a type of toy that has become increasingly popular in recent years, 3D magnetic educational building blocks can be used to construct three-dimensional models and help develop children's imagination. The existing magnetic building blocks on the current market have single stacking angles. The magnetic building blocks may be typically stacked along a same axis, and the playing mode is singular, so more connecting modes can not be achieved. For example, the design and construction of misaligned models can not be made, so that children's interest in building models is adversely affected. Therefore, on the market, it is urgent to provide a magnetic building block with various stacking angles, multiple connecting modes, and rich playing modes, so as to realize the design and construction of misaligned models, improve children's interest in building models, and help develop their imagination.

SUMMARY

In order to overcome the shortcomings of the prior art, the present disclosure provides a magnetic building block.

The magnetic building block includes a building block main body. The building block main body is a square building block main body and is formed by six interconnected side walls.

The six side walls include a front side wall, a rear side wall, a left side wall, a right side wall, an upper side wall, and a lower side wall.

The building block main body includes four inner wall assemblies. The four inner wall assemblies respectively correspond to four seams formed by the front side wall, the rear side wall, the left side wall, and the right side wall.

Each inner wall assembly is respectively located at a corresponding junction formed by two corresponding adjacent side walls. Each inner wall assembly includes at least one inner wall portion, and the inner wall portion is connected to the two corresponding adjacent side walls respectively.

The four inner wall assemblies, the front side wall, the rear side wall, the left side wall, and the right side wall cooperatively define four compartments. Each compartment is defined by at least one inner wall portion of a corresponding inner wall assembly and two corresponding adjacent side walls. Each compartment extends from the upper side wall to the lower side wall.

The building block main body further includes four supporting members corresponding to the four compartments. Each supporting member is positioned in a corresponding compartment. Each supporting member is connected to at least one side wall and/or at least one inner wall portion that defines the compartment. The compartment includes an upper compartment space and a lower compartment space.

The building block main body further includes four groups of magnet assemblies. Each group of magnet assembly is arranged in a corresponding compartment. In each compartment, the magnet assembly includes a first magnet member and a second magnet member. The first magnet member and the second magnet member both have an S pole and an N pole. The supporting member includes a first end adjacent to the upper side wall and a second end adjacent to the lower side wall. The first magnet member is positioned in the upper compartment space between the first end and the upper side wall. The first magnet member is capable of rotating within the upper compartment space. The second magnet member is positioned in the lower compartment space between the second end and the lower side wall. The second magnet member is capable of rotating within the lower compartment space.

Beneficial effects of the present disclosure are as follows. The present disclosure provides a magnetic building block. Through the above structure, magnetic building blocks can be magnetically connected via the first magnet member in the compartment arranged at a crossed corner, so that the magnetic building blocks can be interconnected at the seams. Therefore, this realizes misaligned connection of the magnetic building blocks, so as to achieve the design and construction of misaligned models. Compared to the existing magnetic building blocks in the prior art that can be only stacked along a same axis, the new magnetic building block can significantly enrich its construction methods and play modes, which can help children to build more models. Moreover, children can create various pattern combinations according to patterns on the surface of the magnetic building block. Therefore, this greatly improves children's interest in building models, and helps develop their imagination.

Further, the length of the ninth compartment unit 91 is at least twice of that of the ninth magnet unit 93, and the length of the tenth compartment unit 92 is at least twice of that of the tenth magnet unit 94. Through the above structure, the ninth magnet unit slides in the ninth compartment unit, and the tenth magnet unit slides in the tenth compartment unit, so that the ninth magnet unit and the tenth magnet unit can slide to more positions, and it is convenient for users to achieve the design and building of more misaligned models. Furthermore, the hollow second mounting bracket further reduces the weight of the product. The ninth magnet unit slides in the ninth compartment unit, and the tenth magnet unit slides in the tenth compartment unit, so that the magnetism of the magnetic building block is increased. It should be noted that FIG. 16 only illustrates the structure of the second compartment and does not show any other structures.

In the present embodiment, the second compartment 9 is arranged on an inner wall of the first surrounding wall group. The second compartment 9 extends from a lower side of the first surrounding wall group to an upper side of the first surrounding wall group. The second mounting bracket 95 is arranged at a middle portion of the second compartment 9, so that the second mounting bracket 95 separates the second compartment 9 into the ninth compartment unit 91 arranged on the upper side of the first surrounding wall group and the tenth compartment unit 92 arranged on the lower side of the first surrounding wall group. The second compartment 9 is arranged on the upper side wall, and the second compartment 9 extends from a lower side of the upper side wall to an upper side of the upper side wall. The second mounting bracket 95 is arranged at the middle portion of the second compartment 9, so that the second mounting bracket 95 separates the second compartment 9 into the ninth compartment unit 91 arranged on the upper side of the upper side wall and the tenth compartment unit 92 arranged on the lower side of the upper side wall. Specifically, the second compartment 9 is arranged on lower side wall, and the second compartment 9 extends from a lower side of the lower side wall to an upper side of the lower side wall.

The Fifth Embodiment

Referring to FIG. 21-FIG. 22, a magnetic building block includes a building block main body 1. The building block main body 1 is a square building block main body 1 and is formed by six interconnected side walls.

The six side walls include a front side wall 21, a rear side wall 22, a left side wall 23, a right side wall 24, an upper side wall 25, and a lower side wall 26.

The building block main body 1 includes four inner wall assemblies 50. The four inner wall assemblies 50 respectively correspond to four seams formed by the front side wall 21, the rear side wall 22, the left side wall 23, and the right side wall 24.

Each inner wall assembly 50 is respectively located at a corresponding junction formed by two corresponding adjacent side walls. Each inner wall assembly 50 includes at least one inner wall portion 501, and the inner wall portion 501 is connected to the two corresponding adjacent side walls respectively.

The four inner wall assemblies 50, the front side wall 21, the rear side wall 22, the left side wall 23, and the right side wall 24 cooperatively define four compartments 20. Each compartment 20 is defined by at least one inner wall portion 501 of a corresponding inner wall assembly 50 and two corresponding adjacent side walls. Each compartment 20 extends from the upper side wall 25 to the lower side wall 26.

The building block main body 1 further includes four supporting members 30 corresponding to the four compartments 20. Each supporting member 30 is positioned in a corresponding compartment 20. Each supporting member 30 is connected to at least one side wall and/or at least one inner wall portion 501 that defines the compartment 20. The compartment 20 includes an upper compartment space 201 and a lower compartment space 202.

The building block main body 1 further includes four groups of magnet assemblies 40. Each group of magnet assembly 40 is arranged in a corresponding compartment 20. In each compartment 20, the magnet assembly 40 includes a first magnet member 401 and a second magnet member 402. The first magnet member 401 and the second magnet member 402 both have an S pole and an N pole. The supporting member 30 includes a first end 301 adjacent to the upper side wall 25 and a second end 302 adjacent to the lower side wall 26. The first magnet member 401 is positioned in the upper compartment space 201 between the first end 301 and the upper side wall 25. The first magnet member 401 is capable of rotating within the upper compartment space 201. The second magnet member 402 is positioned in the lower compartment space 202 between the second end 302 and the lower side wall 26. The second magnet member 402 is capable of rotating within the lower compartment space 202. Referring to FIG. 21, the supporting member and the inner wall portion define avoidance gaps 1001, and the supporting member and the side walls also define avoidance gaps 1001.

The avoidance gaps 1001 are configured for avoiding a polishing tool 1002.

Through the above structure, magnetic building blocks can be magnetically connected via the first magnet member in the compartment arranged at a crossed corner, so that the magnetic building blocks can be interconnected at the seams. Therefore, this realizes misaligned connection of the magnetic building blocks, so as to achieve the design and construction of misaligned models. Compared to the existing magnetic building blocks in the prior art that can be only stacked along a same axis, the new magnetic building block can significantly enrich its construction methods and play modes, which can help children to build more models. Moreover, children can create various pattern combinations according to patterns on the surface of the magnetic building block. Therefore, this greatly improves children's interest in building models, and helps develop their imagination. Furthermore, the supporting member and the inner wall portion define avoidance gaps 1001, and the supporting member and the side walls also define avoidance gaps 1001. This enables users to insert a polishing tool 1002 into the avoidance gaps 1001 to polish the supporting member. Moreover, this can address the following issues. First, when it is needed to further increase the magnetic attraction force of the magnetic building blocks, users can insert a polishing tool 1002 into the avoidance gaps 1001 to polish one portion of the first end and one portion of the second end of the supporting member. Therefore, this can reduce a length of the supporting member, so as to increase sizes of the upper compartment space and the lower compartment space, and allow larger magnets to be placed in the upper compartment space and the lower compartment space. In this way, this increases the magnetic attraction force of the building blocks. Additionally, it facilitates free rotation of the magnets within the upper compartment space and the lower compartment space. Second, during the injection molding process of the magnetic building blocks, due to issues related to limitations in mold precision and injection molding accuracy, the length of the supporting member may usually be excessively long, leading to a reduction in the sizes of both the upper compartment space and the lower compartment space. Therefore, it is difficult to mount the magnets into these two compartment spaces. Consequently, the assembly process of the magnetic building blocks becomes more challenging. Moreover, the product rejection rate rises significantly, and the yield rate decreases, which substantially increases the production costs of the magnetic building blocks. To address the issues of mold precision and injection molding accuracy, the polishing tool 1002 can be inserted into the avoidance gaps 1001 to polish portions of the first end and the second end of the supporting member, so as to adjust the length of the supporting member. Therefore, this can enlarge the upper compartment space and the lower compartment space. In this way, users can mount the magnets into the upper compartment space and the lower compartment space more easily, which reduces the rejection rate of the magnetic building blocks and improves the production yield rate. Consequently, this can lower manufacturing costs, and buyers can purchase high-quality magnetic building blocks at a lower price, which is highly beneficial for the target audience of such products.

The supporting member is configured as a cross-shaped supporting member or a T-shaped supporting member.

Referring to FIG. 21-FIG. 22, the avoidance gaps 1001 are positioned between the supporting member and the inner wall portion, as well as between the supporting member and the side walls. Meanwhile, compared to a I-shaped supporting member shown in FIG. 27,

the cross-shaped supporting member or the T-shaped supporting member provides better support for the magnets. The I-shaped supporting member has the following technical problems. The magnets at both ends are prone to displacement or unintended attraction due to the lack of central support. Uneven thickness of the wall, sink marks, or collapse may occur during injection molding cooling. The mold forming efficiency is low. In addition, it is necessary to redesign the mold when changing different magnet specifications. In contrast, the cross-shaped supporting member or the T-shaped supporting member can provide central support to the magnets. This design of the avoidance gaps positioned between the supporting member and the inner walls facilitates subsequent processing and adjustments or adaptation to varying magnet dimensions. This also facilitates mold venting, flow of the injection material, and demolding process, thereby improving versatility of the mold and reducing production costs.

In summary, the cross-shaped supporting member or the T-shaped supporting member has the following functions.

It can better support the upper and lower magnets, thereby preventing displacement due to gravity or magnetic forces during assembly.

It can enhance the structural rigidity of the building block main body, thereby preventing central collapse during injection molding.

It serves as a datum for mold positioning, thereby improving the alignment accuracy between the inner and outer molds.

It provides spacing between magnets, thereby preventing magnetic interference and misorientation due to adhesion.

It facilitates subsequent processing and adjustments by providing the avoidance gaps, so as to adapt for magnets of different specifications.

It reduces maintenance costs of the mold, and enables the same mold to adapt for different products by replacing the supporting poles.

Experimental results show that, compared to the I-shaped supporting member, the magnetic attractive force of the cross-shaped supporting member or the T-shaped supporting member increases by approximately 15% to 25%.

Furthermore, due to the fixed position and consistent orientation of the magnets, the magnetic attraction effect during assembly is more stable and reliable.

Additionally, the supporting member serves as an internal structural reinforcement member, it can distribute internal stress when the building block is subjected to external impact or dropping. Therefore, this can prevent detachment of the magnets or fracture of the housing, so as to significantly enhance the safety and durability of the toy. According to results of the drop test, the magnetic building blocks of the present disclosure exhibits a magnet loosening rate of less than 1% after being dropped from a height, which is far better than traditional products without the supporting member (the traditional magnetic building blocks have an average magnet loosening rate of approximately 8%-10%).

In a further embodiment, the magnets of the building block main body are arranged at four right-angled corner positions, and a central space can be used to mount a bearing. This enables motion transmission or functional expansion with external components, such as forming a gyro-style rotating shaft or a doll structure.

Therefore, the cross-shaped supporting member or the T-shaped supporting member of the present disclosure not only enhances stability of the mold and structural rigidity of the building blocks at the manufacturing level, but also provides spatial foundation for multi-dimensional assembly and mechanical linkage at the functional level.

In the present embodiment, a ratio of a length of the inner wall and a length of the supporting member is at least 1.1:1. A ratio of a volume of the upper compartment space and a volume of the first magnet member is at least 1.1:1. Through the above structure, the first magnetic member is enabled to freely rotate within the upper compartment space and adjust the orientation of its magnetic poles, thereby facilitating the assembly of the building blocks.
