Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the following detailed description is provided with reference to the accompanying drawings:

referring to fig. 1, 2 and 3, five basic elements constituting the three-dimensional block are a cube, a regular tetrahedron, a right-angled isosceles triangular pyramid, a right-angled regular triangular prism and a full equilateral regular triangular prism, respectively.

The embodiment of the utility model provides a, a magnetic force body connection structure who constitutes five basic subassemblies of three-dimensional building blocks, five basic subassemblies magnetic force body connection structure includes that the apex angle adds central magnetic structure, one side central magnetic structure and two magnetic structure of one side.

First, apex angle adds central magnetic force structure

The top corner and center magnetic structure comprises a magnet arranged at each top corner of each basic assembly, a magnet arranged at the center of the regular triangular surface of each basic assembly, and a magnet arranged at the center of the rectangular surface of each basic assembly.

Referring to fig. 4, when the basic component is a cube, the vertex angle plus center magnetic force structure includes eight magnets d, and the eight magnets d are correspondingly disposed at the eight vertex angles of the cube.

Referring to fig. 5, when the basic component is a regular tetrahedron, the vertex-angle-plus-center magnetic structure includes eight magnets, wherein four magnets d are disposed at four vertices of the regular tetrahedron in a one-to-one correspondence, and the other four magnets z1, z2, z3, and z4 are disposed at center positions of four regular triangle faces ABC, ACD, ADB, and BCD of the regular tetrahedron in a one-to-one correspondence.

Referring to fig. 6, when the basic assembly is a right-angled isosceles right triangular pyramid, the vertex angle plus center magnetic structure includes five magnets, wherein four magnets d are correspondingly disposed at four vertex angles of the right-angled isosceles right triangular pyramid one by one, and the remaining one magnet z is disposed at a center position of a right triangular face ABC of the right-angled isosceles right triangular pyramid.

Referring to fig. 7, when the basic component is a right-angle regular triangular prism, the vertex angle plus center magnetic structure includes seven magnets, wherein six magnets d are correspondingly disposed at six vertex angles of the right-angle regular triangular prism, and the remaining one magnet z is disposed at a center position of a rectangular surface BB' C of the right-angle regular triangular prism.

Referring to fig. 8, when the basic component is a regular equilateral triangular prism, the vertex angle plus center magnetic structure includes eight magnets, wherein six magnets d are correspondingly disposed at six vertex angles of the regular equilateral triangular prism, and the other two magnets z1, z2 are correspondingly disposed at the center positions of two regular triangular faces ABC, a ' B ' C ' of the regular equilateral triangular prism.

Referring to fig. 9, 10, 13 and 14, when the regular tetrahedron is hollow, the regular tetrahedron is surrounded by four regular triangular surfaces, three of the regular triangular surfaces form a regular tetrahedron shell (see fig. 9), the other regular triangular surface forms a regular triangular cover plate (see fig. 13), and the regular tetrahedron shell and the regular triangular cover plate are connected to form a hollow regular tetrahedron (see fig. 14). The magnets are mounted at the vertices and at the center of the faces within the regular tetrahedron.

A fan-shaped cone containing cavity c1, c2, c3 and c4 is arranged inside each top corner of the regular tetrahedron, and the magnet is movably arranged in the corresponding fan-shaped cone containing cavity; a cylindrical containing cavity c5, c6, c7 and c8 is arranged at the center position of each regular triangular face of the regular tetrahedron, and the magnet is movably arranged in the corresponding cylindrical containing cavity (see figure 10).

Specifically, referring to FIG. 10, the lines outline the regular triangular EFG plastic sheet, which contains four smaller regular triangles ABC, ABE, ACG and BCF. AB. BC and CA are folded edges, and the other three triangles except the regular triangle ABC can be folded along the three edges and the edges are folded. The thick lines are the processed shapes, and three semicircles are respectively dug at the midpoints of EF, FG and GE, and three sectors are respectively dug at the vertexes of the regular triangle EFG. When three triangles other than triangle ABC are folded and aligned, four fan-shaped cone containing cavities c1, c2, c3 and c4 are formed, and four magnets are contained, and the size is controlled, so that the magnets can move in a small range when being arranged at four vertexes in a regular tetrahedron shell. In addition, at the center of the four regular triangles ABC, ABE, ACG and BCF, there are four cylinders c5, c6, c7 and c8, each of which has an opening from the back to place a magnet, enabling it to move within a small range when mounted in a regular tetrahedron housing. The middle point of each side of the regular triangle ABC is provided with a rectangular hole k which is used for passing through the mortise and tenon of the regular triangle cover plate so that the regular triangle cover plate is firmly clamped with the regular tetrahedron shell.

The mortise and tenon structure used when the regular triangular cover plate is clamped with the regular tetrahedron shell is described. CN2019202704835 discloses a three-dimensional building block with a planar structure, which adopts a planar structure of magnetic materials and open mortise and tenon, and is also applied to a connection structure of open mortise and tenon, in fig. 10, two planes form a pair of clamps at a certain angle, and cannot adopt a closed mortise and hole. The EB edge is provided with an open mortise n and a tenon p, and the BF edge is also the same. When the triangle they are in is folded and mated, the EB side is mated with the BF side. At the moment, the mortise n of the EB edge is clamped with the BF edge tenon head p, and the mortise n of the BF edge is clamped with the EB edge tenon head p to form mortise joint. The mortise and tenon structure is also used for clamping and mounting the regular triangular cover plate and the regular tetrahedron shell.

Referring to fig. 11, 12, 13 and 15, the right-angled isosceles triangular pyramid is hollow and is formed by three right-angled isosceles triangular surfaces and one regular triangular surface, wherein the three right-angled isosceles triangular surfaces form a right-angled isosceles triangular pyramid housing (see fig. 11), and the one regular triangular surface forms a regular triangular cover plate (see fig. 13). The right-angle isosceles triangular pyramid shell and the right-triangle cover plate are connected to form a hollow right-angle isosceles triangular pyramid (see fig. 15). The magnet is arranged at each vertex in the body and the central position of each inner surface, a right-angle vertex angle hollow cone containing cavity c1, c2, c3 and c4 is arranged inside each vertex angle of the right-angle isosceles triangular pyramid, and the magnet is movably arranged in the corresponding right-angle vertex angle hollow cone containing cavity; a cylindrical accommodating cavity c5 is arranged at the center of the regular triangular surface of the right isosceles triangular pyramid, and the magnet is movably arranged in the corresponding cylindrical accommodating cavity (see fig. 12).

Specifically, referring to fig. 12, connected to the regular triangle ABC are three isosceles right triangles ABE, ACG and BCF. Because a cone with a right-angle vertex angle is formed during folding and involution, a processing method different from that of the regular tetrahedron inner frame is adopted. Firstly, a square is dug out of each of the three right-angle top angles of the three right-angle isosceles triangles, so that when the three right-angle isosceles triangles are combined, a hollow cone with the right-angle top angle is formed to accommodate the magnet. In order to prevent the magnet from falling off and combine the requirements of clamping and fixing, an F-shaped mortise and tenon connecting piece is constructed. The F-shaped mortise and tenon connecting piece forms a cubic cavity when the three right-angled isosceles triangles are involuted, and the size of the cavity is slightly larger than the diameter of the magnet, so that the magnet can move in the cubic cavity. In the right-angle isosceles triangular pyramid, an F-shaped mortise and tenon connecting piece is arranged on the inner wall surface at the right angle of each right-angle isosceles triangular surface, and when three right-angle isosceles triangles are combined in a face-to-face mode, every two adjacent F-shaped mortise and tenon connecting pieces are connected in a clamped mode to form a cubic cavity.

The F-shaped mortise and tenon connecting piece is different from a three-head structure on each side used by the regular tetrahedron inner frame, wherein two ends of the three-head structure form a space for mortise and tenon, and the other end of the three-head structure forms tenon. When the F-shaped mortise and tenon connecting pieces are matched, mortise n (a mortise is formed between two transverse lines of the F shape) is arranged at two ends of each F-shaped mortise and tenon connecting piece, and tenon p is arranged at the other end of each F-shaped mortise and tenon connecting piece. The novel T-shaped mortise is a traditional butt joint clamping mode, and is different from the traditional butt joint clamping mode that the T-shaped mortise is obliquely inserted by 90 degrees, and three ends are placed at positions near a top angle according to requirements to form an F-shaped mortise.

Except the above, the rest is the same as the inner frame of the regular tetrahedron, and the description is omitted.

Two-piece and one-piece magnetic structure

Referring to fig. 16, 19 and 22, the three pictures are respectively a square, a regular triangle, a right isosceles triangle, which are the most typical shapes of all the faces of the five basic elements. Each perimeter is marked with two sheets of magnetic sheet in the shape of N, S, which are symmetrical to the perpendicular bisector of each side and are equidistant from each side. Therefore, 8 pieces need to be placed in the square, 6 pieces need to be placed in the regular triangle, and 6 pieces need to be placed in the right-angled isosceles triangle. When the two square sheets are combined, NS poles rotating 90 degrees at each time are mutually attracted, and when the two regular triangle sheets are combined, NS poles rotating 120 degrees at each time are mutually attracted. Because each side of the right-angled isosceles triangle is asymmetric to the center, if the two sides are involuted, the rotation angle is not significant.

CN2019202704835 discloses a three-dimensional building block with a planar structure, which describes that six identical squares can be inscribed into a cube, four identical regular triangles can be inscribed into a regular tetrahedron, and three identical right-angled isosceles triangles and one identical regular triangle can be inscribed into a right-angled isosceles triangular pyramid. A regular tetrahedron and three right-angled isosceles regular triangular pyramids can be spliced into a small cube. This cube consisted of 20 triangles, which required 120 magnetic sheets according to the previous design. If a two-step (2x2x2) magnet is constructed with 8 small cubes, 960 magnetic flakes are required, which is a not insignificant number.

For cost reasons, fig. 15 (square), fig. 18 (regular triangle) and fig. 21 (right isosceles triangle) are designed to be fully attracted to each other regardless of the corner. This design saves magnetic material, but only at the proper angle the two faces can be attracted together. For example, two regular triangle surfaces are opposite, only when the N pole is opposite to the S pole, the two regular triangle surfaces can be opposite to each other for attraction, and other angles generate attraction deviation, that is, when one angle attracts, the two regular triangle surfaces rotate by 120 degrees or 240 degrees and cannot be attached to each other for attraction. Similarly, only one angle of the two square faces, in which the N pole is opposite to the S pole, can be oppositely attracted, and other angles cannot be oppositely attracted, so that the inconvenience brought by cost saving is realized.

Referring to fig. 17, 20 and 23, for cost reasons, a one-sided two-piece magnetic structure is designed, which includes two pieces of magnets disposed on each side of each basic assembly, and the two pieces of magnets on each side are disposed along the same side of the corresponding side with opposite magnetic poles. Two pieces of magnets N, S are provided on the square face (see fig. 17). The regular triangle surface is provided with two magnets N, S (see fig. 20), and the right-angled isosceles triangle surface is provided with two magnets N, S (see fig. 23).

The two-piece magnetic structure on one side is designed by only seeking total equal-side mutual attraction without considering the rotation angle. This design saves magnetic material, but only at the proper angle the two faces can be attracted together. For example, two regular triangle surfaces (see fig. 20) are aligned, only when the N pole is opposite to the S pole, the alignment attraction can be performed, and other angles generate attraction deviation, that is, when one angle attracts, the rotation of 120 ° or 240 ° cannot be performed by the alignment attraction. Similarly, only one angle of the two square surfaces (see fig. 17) where the N pole and the S pole are opposite can be oppositely attracted, and the other angles cannot be oppositely attracted, which is inconvenient in cost saving.

Three, one-side-one central magnetic structure

The face-to-face central magnetic structure includes magnets disposed at central locations of respective faces of each base assembly. Specifically, referring to fig. 25, a magnet is disposed at the center of each face of the cube. Referring to fig. 26, a magnet is disposed at the center of each surface of the regular tetrahedron, and referring to fig. 27, a magnet is disposed at the center of each surface of the right isosceles triangular pyramid; referring to fig. 28, a magnet is provided at the center of each surface of the right-angled regular triangular prism. A magnet (omitted in the figure) is arranged at the center of each surface of the all-equilateral regular triangular prism. The method of magnet placement can be referred to in the related description herein and will not be further described.

It should be explained that, when six, four, and five magnets are respectively placed in a cube, a regular tetrahedron, a right-angled isosceles regular triangular pyramid, a right-angled regular triangular prism, and a full equilateral right-angled regular triangular prism through inner frames, if the inner frame space is small, the magnets in the frames attract each other, but the magnets are in respective closed windows and are not attracted together. The magnetic field strength of the external magnetic material must be of the same order or even higher than the magnetic field strength of the internal magnet in order to attract the internal magnet. This is accompanied by a problem that, for example, the magnets on the three faces of the regular tetrahedron are attracted to the outside, and at this time, the unused fourth magnet is subjected to the resultant magnetic fields of the six magnets, so that the magnets of the same stage cannot attract the magnets in the internal empty state. The solution is to increase the distance between the magnets in the frame.

Fourth, mortise and tenon substitution structure

In the structure of two magnetic force pieces on one surface, two magnets can be replaced by tenons and mortises in a one-to-one correspondence mode.

The physical topology can be carried out to two designs of magnetic material, and the tenon of mosaic structure is regarded as magnetic material 'S N utmost point, and the mortise of mosaic structure is regarded as magnetic material' S S utmost point.

Referring to fig. 18, the square mortise and tenon structure has only one tenon N on the bottom side, and the rest seven mortise and tenon structures are all mortise and tenon S. When two squares with tenons at the bottom edges are matched, the tenon-mortise joints at the bottom edges can be oppositely pressed, and the reserved holes at every 90-degree rotation can be accommodated into the tenons of the two matching surfaces.

Referring to fig. 21, the mortise and tenon structure with a regular triangle surface has a tenon N1, three mortise S1, S2 and S3, and the angle of the rotatable angle is 120 °, 240 ° and 360 ° (returning to the original position) except the bottom side, so that the structure diagram of the mortise and tenon with a regular triangle surface is simpler than that of the mortise and tenon with a regular square surface. When two regular triangles with tenons on the bottom sides are matched, the tenon-and-mortise joints on the bottom sides can be oppositely pressed, and a hole reserved for 120 degrees in each rotation can be accommodated into the tenons on the two matching surfaces.

Please refer to fig. 23, a mortise and tenon structure of a right-angled isosceles triangle surface. It shares a common graph with the one using magnetic materials, since both can be generalized to physical topologies. Due to a right angle involution, its operation is relatively simple. Whether a magnetic material or a mortise and tenon structure is adopted, only the bottom edges of the two involutory surfaces are coincided, and then the mortise and tenon involutory or the NS pole involutory is realized.

The utility model discloses a constitute magnetic force body connection structure of five basic subassemblies of three-dimensional building blocks, magnetic bead, magnetic sheet, magnetic stripe, magnetic column or magnetic path can be adopted to the magnet. The magnetic material used in the present application is not a magnetic sheet, and magnetic beads or magnetic pillars are used, and the use of magnetic beads or magnetic pillars is not the best method for producing a magnetic body. Magnetic bodies (originally called polyhedrons) have been on the market for 25 years now, and no manufacturer is willing to accept production in the late years, and high cost is a fundamental reason. Russia has a manufacturer to use the magnetic circuit design of the NS pole sequence, namely the regular triangle surface also uses 6 magnetic sheets, and the magnetic circuit design of the NS pole sequence is also adopted, but the cube is not cut open, and the cube cannot be formed by components. For example, refer to fig. 24, which shows the magnet arrangement sequence of the "mag cube". Russian manufacturers need to intervene in the magnetic toy market of China, and then domestic enterprises are interested in the concept of the magnetic body of the Russian manufacturers. The above design concept is achieved for the purpose of reducing the production cost and the cost of the consumer.

The utility model discloses a constitute magnetic force body connection structure of five basic subassemblies of three-dimensional building blocks, when writing the magnet and placing, all talk about the magnet and need the activity, this is different from placing of magnetic sheet. The magnetic sheet can be pressed and connected at a fixed position, the magnetic sheet is not allowed to move, but the magnetic bead or the magnetic column must have a space for rotation or jumping, otherwise, the magnetic bead or the magnetic column cannot be used for multiple purposes, and even is blocked.

When the magnets in the plane approach, under the guidance of magnetic lines of force of the magnetic field, the two magnets can quickly jump to the NS pole to attract each other, and at the moment, the magnets of the same level can not rob the NS pole attraction even being close to each other and can only receive the weak magnetic field of the deflected magnetic lines of force. Unless the magnetic field strength is higher by one level, the magnet close to the magnetic field strength can be seized, and the other magnet can only receive the weak magnetic field for deflecting the magnetic field lines. For example, when two sides of a magnet attract each other, the square side of the third cube can only receive a weak magnetic field for deflecting magnetic lines of force, which is a disadvantage of using magnetic beads or columns. Therefore, a magnetic bead or a magnetic column is added at the geometric center of each regular triangle surface to solve the problem that after the priority is given to the magnets at the three vertexes of the regular triangle, one magnetic bead or one magnetic column is reserved to enable the magnetic bead or the magnetic column to be effectively attached to the geometric center of the other regular triangle surface. This situation may arise, for example, when the regular tetrahedron has attracted to each other three right-angled isosceles triangular pyramids, one of which is free. If only one magnetic bead or magnetic column is arranged at the center of each inner surface of the five basic components, the distance between the magnetic bead or the magnetic column needs to be properly increased, and the phenomenon of 'dead absorption' is avoided.

To sum up, the utility model discloses a constitute magnetic force body connection structure of five basic subassemblies of three-dimensional building blocks, simple structure, it is with low costs, and connect firmly.

It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as limitations of the present invention, and that changes and modifications to the above described embodiments will fall within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
