Description

Technical area

[0001] The invention relates to the technical field of building blocks, in particular magnetic building blocks. State of the art

[0002] The early building blocks were mostly made of wood or plastic and were combined by simply connecting, resulting in a relatively simple way of playing. However, with the development of magnetic material technology, magnetic building blocks are gradually being introduced, which utilize the adsorption properties of magnets to make the building blocks more convenient and diverse. The previous magnetic building blocks on the market can only be stacked at a single angle, and generally the magnetic building blocks can only be stacked on the same axis, which represents a single way of playing and does not allow for other connection methods. Therefore, it is necessary to design a new type of magnetic building blocks to meet the design and construction of magnetic building blocks with various stacking angles, multiple connection methods, ample play space, and the ability to realize dislocation modeling. Content of the invention

[0003] The invention is intended to solve the technical problem that the magnetic building blocks of the prior art have only a single stacking angle, which leads to fewer combination possibilities.

[0004] To achieve the above-mentioned purpose, the technical solution of the invention is as follows: Magnetic building blocks comprising a building block body having four or more side walls and two bottom walls which are connected to each other, wherein the connected side walls are enclosed to form a receiving space, and a partition wall is provided in the receiving space, wherein the partition wall separates the receiving space to form an upper receiving space and a lower receiving space, and wherein the partition wall is molded integrally with the side walls; wherein in the upper receiving space, at a junction of the partition wall with an adjacent side wall, an upper partition wall is provided, which is enclosed with adjacent side walls and partition walls to form an upper cell having an opening;and wherein in the lower receiving space, at a junction of the partition wall with an adjacent side wall, a lower partition wall is provided, which is enclosed by adjacent side walls and partition walls to form a sub-cell with an opening; wherein a magnetic element is provided in each of the upper and lower cells, which is freely movable in the upper and lower cells; wherein the bottom wall serves to close the upper and lower cells.

[0005] In this solution, the receiving space is divided into an upper receiving space and a lower receiving space by providing a partition wall in the receiving space of the main body, and an upper cell is formed in the upper receiving space by enclosing the upper partition wall with the side wall and the partition wall, and a lower cell is formed in the lower receiving space by enclosing the lower partition wall with the side wall and the partition wall, and the magnetic building blocks are arranged in the upper and lower cells; the magnetic element can then move freely in the upper and lower cells, and no matter which side of the magnetic building block comes into contact with the other magnetic building block, the magnetic elements in the two magnetic building blocks are attracted to each other, so that the magnetic building blocks can be combined and connected more securely in many different ways.

Concrete embodiments

[0006] In the following, the invention will be explained in more detail in conjunction with the accompanying drawings and specific embodiments. As in Fig. 1 to 5, magnetic building blocks comprise a building block body 1 having four or more side walls 2 and two bottom walls 20 connected to each other, the side walls 2 comprising a front side wall 21, a rear side wall 22, a left side wall 23 and a right side wall 24, and the bottom walls 20 comprising an upper bottom wall 201 and a lower bottom wall 202, the connected side walls 2 being connected to each other to form a receiving space 3, the side wall 2 and the bottom wall 20 being connected to each other in adjacent orientations to form a cube, a partition wall 4 being provided in the receiving space 3 to divide the receiving space 3 into an upper receiving space 31 and a lower receiving space 32;wherein in the upper receiving space 31 on the front side wall 21, the rear side wall 22, the left side wall 23, and the right side wall 24, an upper connecting post 13 is provided, in each of which an upper connecting hole 131 is provided; wherein in the lower receiving space 32 on the front side wall 21, the rear side wall 22, the left side wall 23, and the right side wall 24, a lower connecting post 14 is provided, in each of which a lower connecting hole 141 is provided; wherein on the inside of the upper bottom wall 201, an upper fastening post 211 is provided, which can be inserted into the upper connecting hole 131, and on the inside of the lower bottom wall 202, a lower fastening post 212 is provided, which can be inserted into the lower connecting hole 141.

[0007] As in Fig. 2 to 3, in this embodiment, an upper welding portion 221 is provided at the root of the upper fixing post 211, and after the upper bottom wall 201 is joined to the side wall 2, the upper welding portion 221 is ultrasonically welded to the upper partition wall 11; and a lower welding portion 222 is provided at the root of the lower fixing post 212, the lower welding portion 222 being ultrasonically welded to the lower partition wall 12 after the lower bottom wall 202 is joined to the side wall 2.

[0008] The upper fixing post 211 is connected to the upper connecting hole 131 by a press fit, and the lower fixing post 212 is connected to the lower connecting hole 141 by a press fit, the upper bottom wall 201 is connected to the side wall 2 by the upper fixing post 211 having the upper connecting hole 13, and the lower bottom wall 202 is connected to the side wall 2 by the lower fixing post 212 having the lower connecting post 14, thus forming a relatively closed cube, which forms the entire block body 1; then, the upper welding portion 221 is welded to the upper partition wall 11 and the lower welding portion 222 is welded to the lower partition wall 12 by ultrasonic waves, thereby strengthening the entire block body 1.

[0009] In addition to ultrasonic welding, the upper bottom wall 201 and the lower bottom wall 202 can also be connected to the side wall 2 by a joining method such as gluing, press fitting or snap fitting.

[0010] In this embodiment, the partition wall 4 is integrally injection-molded with the front side wall 21, the rear side wall 22, the left side wall 23, and the right side wall 24, while the upper bottom wall 201 and the lower bottom wall 202 are separately injection-molded. Finally, the upper bottom wall 201 and the lower bottom wall 202 are bonded and encapsulated with the front side wall 21, the rear side wall 22, the left side wall 23, and the right side wall 24. The integral molding of the partition wall 4 and the surrounding side walls 2 enables a more solid internal structure of the building blocks, and the integral structure can better withstand pressure from all directions, ensuring the integrity of the building block shape and also facilitating production.

[0011] As in Fig. 2 to 3, an upper partition 11 is provided in the upper receiving space 31 at the junction of the partition 4 and the adjacent side wall 2. In this embodiment, the upper partition 11 is L-shaped, and the upper partition 11 is connected to the adjacent side wall 2 and the partition 4 to form an upper cell 301. An upper support post 311 is provided in the upper cell 301, the upper support post 311 being arranged on the partition 4. A magnetic element 5 is also provided in the upper cell 301. The magnetic element 5 can be rotated in the upper cell 301, and the upper support post 311 is arranged below the magnetic element 5 so that the magnetic element 5 does not come into contact with the partition 4. The magnetic element 5 in this embodiment is a neodymium-iron-boron magnet.

[0012] In the lower receiving space 32, a lower partition 12 is provided at the junction of the partition 4 with the adjacent side wall 2. In this embodiment, the lower partition 12 is L-shaped, and the lower partition is connected to the adjacent side wall 2 and the partition 4 to form a sub-cell 302. A lower support post 312 is provided in the sub-cell 302, the lower support post 312 being arranged on the partition 4. A magnetic element 5 is also provided in the sub-cell 302. The magnetic element 5 can be rotated in the sub-cell 302, and the lower support post 312 is arranged below the magnetic element 5 so that the magnetic element 5 does not come into contact with the partition 4.

[0013] The magnetic elements 5 located in the upper cell 301 and the lower cell 302 are not adsorbed to each other in the vertical direction in the upper cell 301 and the lower cell 302 because the upper support post 311 and the lower support post 312 respectively push the magnetic elements 5 upward and away from the partition wall 4, so that the magnetic elements 5 in the upper cell 301 and the lower cell 302 on the same side in the vertical direction are not adsorbed to each other, and the distance between the upper cell 301 or the lower cell 302 on the same side in the transverse direction is not large enough to generate a suction force between the magnetic elements 5, so that the magnetic elements 5 in the upper cell 301 and the lower cell 302 can rotate freely.

[0014] As in Fig. 5, in this embodiment, the volume of the upper receiving space 31 is greater than or equal to that of the lower receiving space 32, and this setting can facilitate demolding 3 after injection molding and also the addition of additional accessories such aslight-emitting parts or battery packs, into the upper receiving space 31 during later use without the need for additional molding and manufacturing; the length of the upper support post 311 is greater than the length of the lower support post 312. Since the depth of the lower receiving space 32 is smaller than that of the upper receiving space 31, and the magnetic element 5 must be able to rotate freely in the sub-cell 302, in order to allow the magnetic suction element 5 to rotate freely in the sub-cell 302, the length of the lower support post 312 is relatively short. In addition, the length of the upper support post 311 is longer so that the magnetic attraction force between the magnetic element 5 in the upper cell 301 and the sub-cell 302 on the same side in the vertical direction is smaller than the gravity of the magnetic element 5 itself.

[0015] As in Fig.2 to 3, in this embodiment, an upper reinforcement 41 is provided on the partition wall 4 of the upper receiving space 31, the upper reinforcement 41 extending from the junction of the side wall 2 towards the center, a reinforcing ring 43 being provided in the center of the partition wall 4 of the upper receiving space 31, and the upper reinforcement 41 being connected to the reinforcing ring 43; on the partition wall 4 of the lower receiving space 32, a lower reinforcement 42 is provided, which are perpendicular to each other with respect to the side wall 2 to which it is connected, iethe upper reinforcement 41 is provided at a 45° angle to the lower reinforcement 42; the upper reinforcement 41 transmits the force from the direction of the side wall 2 to the central reinforcement ring 43, which in turn distributes the force evenly among the individual upper reinforcements 41, thus preventing local deformation or damage to the partition walls 4; moreover, the lower reinforcement rib and the upper reinforcement rib are arranged at a 45° angle, so that the partition walls 4 can interact with each other when subjected to forces in different directions, thus forming a spatially complementary structure and improving the durability of the product.

[0016] In this structure, the accommodation space 3 is separated by a partition wall 4, the magnetic element 5 is divided into two accommodation spaces, and an upper cell 301 and a lower cell 302 are formed at the connecting corners of the respective side walls 2 and the bottom walls 20 by dividing them by an upper partition wall 11 and a lower partition wall 12. In this case, the magnetic element 5 in the upper cell 301 and the lower cell 302 can move freely (both translationally and rotationally), and the magnetic elements 5 in both magnetic building blocks are attracted to each other regardless of which side of the magnetic building block is in contact with the other magnetic building block, so that the magnetic building blocks can be combined in various ways and connected more securely.

[0017] In addition, the side wall 2, the partition wall 4, the upper partition wall 11 and the lower partition wall 12 are injection-molded in one piece, which enables easy manufacturing; during assembly, it is only necessary to place the magnetic element 5 in the upper cell 301 and the lower cell 302, and then connect the upper bottom wall 201 and the lower bottom wall 202 to enclose the magnetic element 5 in the upper cell 301 and the lower cell 302, which is a simple step and saves time and effort.
