DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0043] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0045] See also Figures 1 to 11As shown, an embodiment of the present application provides a Rubik's Cube, comprising: a central body component 1 and a plurality of Rubik's Cube blocks 2. The central body component 1 comprises a central body 11 and a plurality of central shafts 12 connected to the central body 11. Each of the Rubik's Cube blocks 2 is arranged on the peripheral side of the central body 11. The Rubik's Cube has a plurality of faces, and each Rubik's Cube block 2 on each face comprises a central block 21 and a plurality of peripheral side blocks 22 located around the edge of the central block 21. The central block 21 is connected to the corresponding central shaft 12, and a limited space is formed between the central block 21 and the central body 11. The central shaft 12 has an exposed section located in the limited space, and at least part of the pins of the peripheral side blocks 22 extend to the limited space and are close to or in contact with the exposed section. The outer wall surface of the portion of the central shaft 12 located in the limited space is smooth to ensure smoothness and stability of the Rubik's Cube during rotation. The central block 21 of the Rubik's Cube of the present application has a smaller extension dimension along the central axis, occupies a small space, and does not extend to the central body 11, so that the central axis 12 has an exposed section located in the limited space, and can make the clamping feet of at least part of the peripheral blocks 22 extend as far as possible toward the central axis 12, or extend a larger dimension, so that each Rubik's Cube block 2 has more limited matching structures, stable rotation, and is not easy to fall apart during rotation.

[0046] like Figure 2 As shown, at least part of the clamping feet of the peripheral side blocks 22c of the outermost circle extend into the limiting space and are close to or in contact with the exposed section. The peripheral side blocks 22c of the outermost circle may be middle edge blocks 222, which are blocks located at the center of the line connecting two adjacent corner blocks of the peripheral side blocks 22c of the outermost circle. Each of the middle edge blocks 222 has more limiting matching structures, good limiting matching effect, stable rotation, and is not easy to fall apart during rotation.

[0047] like Figure 2 As shown, at least some of the peripheral blocks 22b of the secondary outer ring have their feet extending into the limiting space and close to or in contact with the exposed section. At least some of the peripheral blocks 22b of the secondary outer ring may be edge blocks, which are blocks in the peripheral blocks of the secondary outer ring that are in contact with the middle edge blocks 222. This allows each magic cube block 2 to have more limiting matching structures, stable rotation, and prevent disintegration during rotation, making the magic cube of the present application more stable.

[0048] like Figure 5 , Figure 6 and Figure 7 As shown, in each circumferential side block 22 between the center block 21 and the outermost circumferential side block 22c, one of the two contacting Rubik's cube blocks 2 in two adjacent circumferential side blocks 22 has a limiting groove b formed on the bottom of the main shell, and the other has a matching protrusion a formed on the bottom of the main shell, and the matching protrusion a extends into the limiting groove b. Taking the seven-order Rubik's cube as an example, Figure 1As shown, the multi-circle circumferential block 22 includes an inner circumferential block 22a, a sub-outer circumferential block 22b and an outermost circumferential block 22c. The main shell is the part exposed on the surface of the magic cube of the present application, and is roughly in the shape of a block. The matching protrusion a can be slidably embedded in the limiting groove b, and the multiple limiting matching structures have a good limiting effect, so that the magic cube has good stability during the rotation process and is not easy to fall apart.

[0049] like Fig. 9 As shown, the magic cube block 2 includes: a main block body 2a and a clamping foot 2b. The main block body 2a has an exposed surface 2a1 and a friction matching surface 2a2. The friction matching surface 2a2 of at least part of the magic cube block 2 includes a contact surface 2a21 and an avoidance surface 2a22. In the direction perpendicular to the friction matching surface 2a2, the contact surface 2a21 protrudes from the avoidance surface 2a22. The clamping foot 2b is connected to the main block body 2a. When the magic cube with the magic cube block is in a reset state, the exposed surface 2a1 is exposed to the surface of the magic cube, the friction matching surface 2a2 faces the adjacent magic cube block, the contact surface 2a21 contacts the adjacent magic cube block, and a gap is formed between the avoidance surface 2a22 and the adjacent magic cube block, so that the contact area of ​​the adjacent magic cube blocks is small. When the magic cube with the magic cube block is rotated, the friction resistance is small, so that the magic cube rotation resistance is small and the rotation smoothness is high.

[0050] like Fig. 9 As shown, the circumferential edge of the contact surface 2a21 extends to the avoidance surface 2a22 through the arc transition surface 2a23. The circumferential edge of the contact surface 2a21 is smooth and burr-free, with a smooth transition. When the Rubik's Cube with the Rubik's Cube is rotated, the friction resistance is small, the Rubik's Cube has a small rotation resistance, and a high degree of rotation smoothness.

[0051] like Fig. 9 As shown, the avoidance surface 2a22 is at least partially disposed at one end of the friction fitting surface 2a2 away from the clamping foot 2b. The end of the friction fitting surface 2a2 away from the clamping foot 2b is a position close to the edge of the exposed surface 2a1. When the Rubik's Cube with the Rubik's Cube is rotated, the friction force is greater at the position close to the edge of the exposed surface 2a1. The avoidance surface 2a22 is disposed here to reduce the friction resistance.

[0052] like Fig. 9 As shown, the avoidance surface 2a22 is partially arranged on the side of the friction fitting surface 2a2 close to the clamping foot 2b. The side close to the clamping foot 2b has a greater matching tightness and a greater contact pressure, and the avoidance surface 2a22 is partially arranged here to effectively reduce the friction resistance.

[0053] like Fig. 9As shown, the avoidance surface 2a22 located on the side of the friction mating surface 2a2 away from the clamping foot 2b is quasi-triangular. The avoidance surface 2a22 located on the side of the friction mating surface 2a2 away from the clamping foot 2b is connected to the exposed surface 2a1, where the friction force is the largest. The avoidance surface 2a22 is arranged here to reduce the friction resistance. The avoidance surface 2a22 located on the side of the friction mating surface 2a2 close to the clamping foot 2b is strip-shaped.

[0054] The Rubik's Cube block can be any one of an edge block, a corner block 221 and a center block 21. The friction mating surface 2a2 can be set on one of two adjacent Rubik's Cube blocks. For example, when the Rubik's Cube is a five-order Rubik's Cube, the Rubik's Cube mating surface 2a2 is set on the Rubik's Cube block between the middle edge block 222 and the corner block 221 in the outermost circle of the peripheral side block 22c. Fig.10 and Fig.11 When the Rubik's Cube is a seven-order Rubik's Cube, the Rubik's Cube mating surface 2a2 is set on the middle edge block 222 of the outermost peripheral side block 22c, see Figure 1 and Fig. 9 shown.

[0055] like Figure 2 and Figure 4 As shown, a plurality of first magnetic components 3 are arranged on the central body 11, and a second magnetic component 4 is arranged on the corner block 221 of each Rubik's Cube block 2. When the Rubik's Cube is in a reset state, each first magnetic component 3 is respectively opposite to the corresponding second magnetic component 4, and magnetically attracts each other, so that the Rubik's Cube of the present application feels smoother when reset, and is easier to reset.

[0056] like Figure 4 As shown, the end of the foot of the corner block 221 is provided with a convex shell portion 2211, and a sleeve 2211a is provided on one side of the concave surface of the convex shell portion 2211. The second magnetic component 4 is at least partially embedded in the sleeve 2211a. The second magnetic component 4 can be a magnet, and the magnet can be in a round shape, so that the magnet can be bonded to the sleeve 2211a through colloid. This makes the assembly of the second magnetic component 4 very convenient.

[0057] like Figure 5 and Figure 8As shown, the middle edge block 222 in the outermost peripheral block 22c includes an edge block main shell 2221 and an edge block foot 2222, and the edge block main shell 2221 and the edge block foot 2222 are detachably connected. In the prior art, the edge block 222 main shell and the edge block foot 2222 are integrally formed as a one-piece. During the production process, the precision requirements for the mold are high, and the size difference of the finished product is large, which makes the yield rate low, and the quality stability of the produced edge block is poor, which affects the normal use of the magic cube of the present application. The magic cube of the present application sets the edge block main shell 2221 and the edge block foot 2222 into a detachable structure. The edge block main shell 2221 and the edge block foot 2222 can be injection molded separately, and each component is produced and manufactured separately using a corresponding mold. The structure of each component after disassembly is simple, the precision requirements for the mold are low, and the size difference of the finished product is small, so that the yield rate is high, and the quality stability of the produced middle edge block 222 is good.

[0058] like Figure 8 As shown, the main shell 2221 of the middle edge block 222 may include two half main shells. The two half main shells are detachably connected, and a limit cavity 2221e and a connecting groove 2221f connecting the limit cavity 2221e are formed between the two half main shells. The two half main shells have the same structure, so that the size of the mold for producing the main shell 2221 of the edge block is reduced, and the types of molds for producing the main shell 2221 of the edge block are reduced, so that the production of the main shell 2221 of the edge block is high in precision and yield. The half main shells are each provided with a slot 2221a and an insert shaft 2221b. When the two half main shells are connected, the insert shaft 2221b of one is inserted into the slot 2221a of the other, and the two half main shells are buckled together to form a complete middle edge block 222. The plug-in matching method has a simple structure, convenient assembly, and high assembly efficiency. The edge block foot 2222 is arranged to penetrate the connecting groove 2221f, and the edge block foot 2222 includes a connecting portion 2222a and a foot body 2222b, wherein the connecting portion 2222a is limited in the limiting cavity 2221e, and the foot body 2222b is exposed from the edge block main shell 2221. When assembling the middle edge block 222, the connecting portion 2222a is partially embedded in the limiting cavity 2221e of one of the half main shells, and then connected to the other half main shell. The assembly is convenient and the assembly efficiency is improved.

[0059] like Figure 5 and Figure 8 As shown, the two half-main shells each have two half friction fit surfaces 2a2. When the two half-main shells are connected, the half friction fit surfaces 2a2 of the two half-main shells are spliced ​​to form a complete friction fit surface 2a2. When the two half-main shells are connected, the two half-main shells form a splicing seam 2221d, and the splicing seam 2221d is located on the friction fit surface 2a2.

[0060] The Rubik's Cube is a 5th-order Rubik's Cube or a 7th-order Rubik's Cube. The Rubik's Cube can be a 5th-order Rubik's Cube, a 7th-order Rubik's Cube or other high-order Rubik's Cube.

[0061] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model has been disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this patent can make some changes or modify the technical content suggested above into an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still falls within the scope of the solution of the utility model.
