The application claims priority of Chinese patent application CN2022229072262, filed on 2022 Nov. 1, which is incorporated herein by reference in its entireties.
The present disclosure relates to the field of magnetic toy bricks, and more particularly to, a polyhedral magnetic toy brick and a combined structure.
Toy bricks are a common educational toy. Various shapes are individual basic elements, and the elements can be combined into multiple different shapes in specific ways. Combination methods include plugging, magnetic attraction, and the like. For magnetic toy bricks, N-pole and S-pole magnets attract each other, to achieve construction of two toy bricks. For example, the invention patent No. CN2019217830934 and entitled “a magnetic toy brick combination”, in which a toy brick is composed of a cloth outer skin, a sponge body filling the cloth outer skin, and a magnet arranged between the cloth outer skin and the sponge body. Furthermore, an outward face of the magnet on at least one face of the toy brick is an N pole, and an outward face of the magnet on at least one face of the toy brick is an S pole; and the outward magnetisms of the magnets on the same faces of the toy bricks are consistent, so that two toy bricks are combined by magnetic attraction between one face and another face.
The magnet in the above patent is adhered to the sponge body, so that the magnet is easily separated from the sponge body, and moves. As a result, a combined model is unstable and would even topple over. In addition, in the toy brick structure of the aforementioned patent, the outward magnetisms of the magnets on the same face are the same, to ensure that the faces of the two toy bricks are aligned. A first toy brick and a second toy brick are taken as an example. The first toy brick and the second toy brick each have four faces, two of which are N-pole faces with outward magnetisms of N poles and the other two of which are S-pole faces with outward magnetisms of S poles. It can be seen that the first toy brick only has two N-pole faces connected to the S-pole faces of the second toy brick, that is, the N-pole faces of the first toy brick cannot be connected to the N-pole faces of the second toy brick, and the S-pole faces of the first toy brick cannot be connected to the S-pole faces of the second toy brick, so that the possibility and degree of freedom of constructing models are restrained.

The present disclosure is further described below in detail in combination with the accompanying drawings and embodiments.
In order to explain the technical solutions of the embodiments of the present disclosure more clearly, the following will briefly introduce the accompanying drawings used in the embodiments. Apparently, the drawings in the following description are only some embodiments of the present disclosure. Those of ordinary skill in the art can obtain other drawings based on these drawings without creative work.
As shown in
The inner-layer assembly 10 is formed by splicing the several board bodies 11, and the outer skin assembly wraps the outer surface of the inner-layer assembly 10, so that the polyhedral magnetic toy brick with good structural strength and stability can be formed. Furthermore, the magnet mounting holes 12 for accommodating the magnets 20 are formed in the magnetic face 100 of the board body 11, so that the magnets 20 can be stably fixed on the board body 11 and is avoided from being separated or moving and even toppling over relative to the board body 11, and magnetic connection between the toy bricks can be guaranteed; and different models can be combined. In addition, the same magnetic face 100 has two magnets 20 with opposite outward magnetisms. In this way, when two toy bricks are connected, the N-pole magnet on one magnetic face 100 is in magnetic fit with the S-pole magnet on the other magnetic face 100, that is, the two magnetic faces 100 are magnetically connected through the two groups of N and S-pole magnets, which ensures that the vertexes, the edges, and the faces of the two magnetic faces 100 are kept in completely overlapping under the magnetic action, so that inconvenience in modeling and combination processes caused by turning, sliding, or other phenomena in a combination process is avoided. Meanwhile, for traditional toy bricks provided with the magnets having the same magnetisms on each face, two toy bricks of the present disclosure can be combined through any magnetic face 100, which improves the degree of freedom of combination and the diversity of models.
As shown in
The board bodies 11 and the outer skin assembly may be made of resin, for example, an Acrylonitrile Butadiene Styrene (ABS) resin material, so that after the outer skin assembly wraps the outer surface of the inner-layer assembly 10, the magnetisms of the magnets 20 will not be affected. The outer skin assembly includes at least two outer skins. The two outer skins wrap the outer surface of the inner-layer assembly, and are sutured by ultrasonic waves to ensure the connection strength between the outer skins. It should be noted that a shape of the polyhedral magnetic toy brick depends on the inner-layer assembly 10. The outer skin assembly wraps the outer surface of the inner-layer assembly 10, so that the polyhedral magnetic toy brick defined by the shape of the inner-layer assembly 10.
The magnet mounting holes 12 may be formed in an outer surface of each board body 11. The magnets 20 may be fixed in the magnet mounting holes 12 in an embedding, step clamping, adhesion, or combination manner, to ensure that the magnets 20 are stably fixed on the board body 11.
Referring to
It should be noted that the outward magnetisms of the magnets of each board body in the prior are the same, while each magnetic face 100 of the present disclosure is provided with the two magnets 20 with opposite outward magnetisms to connect the board bodies 11 with different shapes. For example, one board body 11 is triangular, and the other board body 11 is rhombic. Due to the two magnets 20 with the opposite outward magnetisms on the magnetic faces 100, the triangular board body 11 can be magnetically connected to the magnetic face 100 of one triangle of the rhombic board body 11. Furthermore, the two magnetic faces 100 are aligned. It can be seen that the board bodies 11 with different shapes are formed by taking the magnetic faces 100 as units, so that the board bodies 11 with different shapes are connected, to increase the possibility of constructing models. It is worth mentioning that the outward magnetisms of the magnets of each board body are the same in the prior art. When two board bodies with different shapes are combined, the smaller board body cannot be constructed at a specified position of the larger board body, which will affect the experience of construction.

In addition, the second board body 11c2 is also plugged to the third board body 11c3, the fourth board body 11c4, and the sixth board body 11c6 respectively, so as to fold the board bodies to form the oblique quadrangular prism as shown in

From the above embodiments, it can be seen that the board bodies 11 constituting the inner-layer assembly 10 may be the same or different in shape. In this way, the board bodies can be folded to form the polyhedral magnetic toy bricks with different shapes, which provides more possibilities for construction of combined models. In addition, the board bodies 11 constituting the inner-layer assembly 10 can be integrally molded and are then plugged. Two adjacent board bodies 11 that are integrally molded can rotate each other, which reduces the assembling difficulty and ensures the manufacturability. In addition to the above shapes, the polyhedral magnetic toy bricks can also be made into different shapes by adjusting the quantity, shapes, and sizes of the board bodies 11.
In conclusion, the inner-layer assembly 10 is formed by splicing the several board bodies 11, and the outer skin assembly wraps the outer surface of the inner-layer assembly 10, so that the polyhedral magnetic toy brick with good structural strength and stability can be formed. Furthermore, the magnet mounting holes 12 for accommodating the magnets 20 are formed in the magnetic face 100 of the board body 11, so that the magnets 20 can be stably fixed on the board body 11 and is avoided from being separated or moving relative to the board body 11, and magnetic connection between the toy bricks can be guaranteed; and different models can be combined. In addition, the same magnetic face 100 has two magnets 20 with opposite outward magnetisms. In this way, when two toy bricks are connected, the N-pole magnet on one magnetic face 100 is in magnetic fit with the S-pole magnet on the other magnetic face 100, that is, the two magnetic faces 100 are magnetically connected through the two groups of N and S-pole magnets, which ensures that the vertexes, the edges, and the faces of the two magnetic faces 100 are kept in completely overlapping under the magnetic action, so that inconvenience in modeling and combination processes caused by turning, sliding, or other phenomena in a combination process is avoided. In addition, the board bodies 11 constituting the inner-layer assembly 10 can be integrally molded and are then fixed by plugging, which reduces the assembling difficulty and ensures the manufacturability.
The present disclosure further provides a combined structure, including at least two polyhedral magnetic toy bricks of any of the above embodiments. The two polyhedral magnetic toy bricks are connected through the magnetic faces 100.

Furthermore, the combined structure can be constructed by the polyhedral magnetic toy bricks with different or same shapes, and can be magnetically connected through the board bodies 11 with different shapes. In this way, the possibility of constructing models can be effectively increased. When two board bodies 11 with different shapes are magnetically connected, since the board bodies 11 take the magnetic faces 100 as a unit, the two magnetically connected board bodies 11 can be magnetically connected through the magnetic faces 100. The N-pole magnet on one magnetic face 100 is in magnetic fit with the S-pole magnet of the other magnetic face 100. That is, the two magnetic faces 100 are magnetically connected through the two groups of N and S-pole magnets, so that it is ensured that the two magnetic faces 100 are aligned, which ensures that the board bodies 11 with different shapes can be constructed stably and further achieves the diversification of constructing models.
