DETAILED DESCRIPTION

[0043] 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.

[0044] 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.

[0045] 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. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] Example 1: See Figure 1 to Figure 2As shown, the first embodiment of the present disclosure provides a Rubik's Cube 2 with low resistance, including: a main block 2a and a clamping foot 2b. The main block 2a has an exposed surface 2a1 and a friction fitting surface 2a2, and the friction fitting surface 2a2 includes a contact surface 2a21 and an avoidance surface 2a22. In a direction perpendicular to the friction fitting surface 2a2, the contact surface 2a21 protrudes from the avoidance surface 2a22. The clamping foot 2b is connected to the main block 2a. When the Rubik's Cube with the Rubik's Cube is in a reset state, the exposed surface 2a1 is exposed to the surface of the Rubik's Cube, the friction fitting surface 2a2 faces the adjacent Rubik's Cube block, the contact surface 2a21 contacts the adjacent Rubik's Cube block, and a gap is formed between the avoidance surface 2a22 and the adjacent Rubik's Cube block. The Rubik's Cube block with low resistance of the present application includes a contact surface 2a21 and an avoidance surface 2a22, wherein the contact surface 2a21 is in direct contact with an adjacent Rubik's Cube block, and a gap is formed between the avoidance surface 2a22 and the adjacent Rubik's Cube block, so that the contact area of ​​the adjacent Rubik's Cube blocks is small. When the Rubik's Cube having the Rubik's Cube block is rotated, the friction resistance is small, so that the Rubik's Cube rotation resistance is small and the rotation smoothness is high.

[0047] The side edge of the contact surface 2a21 extends to the avoidance surface 2a22 through the arc transition surface 2a23, so that the side edge of the contact surface 2a21 is smooth and burr-free, and the transition is smooth. When the magic cube with the magic cube is rotated, the friction resistance is small, so that the magic cube has small rotation resistance and high rotation smoothness.

[0048] In a possible implementation, 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 having the Rubik's Cube block rotates, 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.

[0049] 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 friction resistance.

[0050] The avoidance surface 2a22 located on the side of the friction fitting surface 2a2 away from the clamping foot 2b is quasi-triangular. The avoidance surface 2a22 located on the side of the friction fitting surface 2a2 away from the clamping foot 2b is connected to the exposed surface 2a1, where the friction force is the largest, and the avoidance surface 2a22 is arranged here to reduce the friction resistance. The avoidance surface 2a22 located on the side of the friction fitting surface 2a2 close to the clamping foot 2b is strip-shaped.

[0051] In a possible implementation, the Rubik's Cube with low resistance can be any one of an edge block, a corner block 221 and a center block 21. For a Rubik's Cube with the Rubik's Cube with low resistance of the present application, the friction mating surface 2a2 can be provided on one of two adjacent Rubik's Cube blocks.

[0052] In a possible implementation, the main block 2a and the clamping foot 2b are detachably connected. In the prior art, the main block 2a and the clamping foot 2b are integrally formed. During the production process, the precision requirements for the mold are high, and the size differences of the finished products are large, which leads to a low yield rate and poor quality stability of the edge blocks produced, affecting the normal use of the Rubik's Cube of this application. The Rubik's Cube with this Rubik's Cube has a detachable connection structure between the main block 2a and the clamping foot 2b. The main block 2a and the clamping foot 2b can be injection molded separately, and each component is produced separately using a corresponding mold. The disassembled components have a simple structure and a small size, and the precision requirements for the mold are low. The size differences of the finished products are small, which leads to a high yield rate and good quality stability of the Rubik's Cube blocks produced.

[0053] like Figure 2 As shown, the main block 2a includes two half main shells 2a3. The two half main shells 2a3 are detachably connected, and a limit cavity 2a33 and a connecting groove 2a34 connecting the limit cavity 2a33 are formed between the two half main shells 2a3. The two half main shells 2a3 have the same structure, which reduces the size of the mold for producing the main block 2a, and reduces the types of molds for producing the main block 2a, so that the production of the main block 2a is high in precision and high in yield. The half main shells 2a3 are each provided with a slot 2a31 and an insert shaft 2a32. When the two half main shells 2a3 are connected, the insert shaft 2a32 of one is inserted into the slot 2a31 of the other, and the two half main shells 2a3 are buckled together to form a complete main block 2a. The plug-in matching method has a simple structure, convenient assembly, and high assembly efficiency. The clamping foot 2b is arranged to penetrate the connecting groove 2a34, and the clamping foot 2b includes a connecting portion 2b1 and a clamping foot body 2b2, wherein the connecting portion 2b1 is limited in the limiting cavity 2a33, and the clamping foot body 2b2 is exposed from the main block 2a. When assembling the Rubik's Cube with low resistance of the present application, the connecting portion 2b1 is partially embedded in the limiting cavity 2a33 of one of the semi-main shells 2a3, and then connected to the other semi-main shell 2a3. The assembly is convenient and the assembly efficiency is improved.

[0054] Example 2: See 3 to Fig.11 As shown, the embodiment of the present application also provides a magic cube, including: a plurality of magic cube blocks 2 with low resistance as described above. When the magic cube of the present application is rotated, the friction resistance is small, so that the magic cube has low rotation resistance and high rotation smoothness.

[0055] The Rubik's Cube comprises: 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. At least some of the Rubik's Cube blocks 2 are the Rubik's Cube blocks with low resistance, and each of the Rubik's Cube blocks is arranged on the peripheral side of the central body 11. The Rubik's Cube has a plurality of faces, and each of the Rubik's Cube blocks 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 21. The central shaft 12 has an exposed section located in the limited space, and at least some of the peripheral side blocks 22 have their feet extending to the limited space and 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 the smoothness and stability of the Rubik's Cube during rotation. The connecting column of the center block 21 of the Rubik's Cube of the present application is relatively small in size, occupies little space, and does not extend to the center body 11, so that the center axis 12 has an exposed section located in the limited space, and the clamping feet of at least part of the peripheral blocks 22 can be extended as far as possible toward the center axis 12, or the extended size is larger, so that each Rubik's Cube block 2 has more limited matching structures, stable rotation, and is not easy to fall apart during rotation.

[0056] like Figure 4 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.

[0057] like Figure 4 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.

[0058] like Figure 7 , Figure 8 and Fig. 9 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 3As 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.

[0059] In one possible embodiment, Figure 4 and Figure 6 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.

[0060] like Figure 6 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.

[0061] In a possible implementation, the Rubik's Cube may be a fifth-order Rubik's Cube, a seventh-order Rubik's Cube, or any other high-order Rubik's Cube. For example, when the Rubik's Cube is a fifth-order Rubik's Cube, the Rubik's Cube block 2 with low resistance may be a Rubik's Cube block between the middle edge block and the corner block 221 in the outermost peripheral block 22c. Fig.10 and Fig.11 When the Rubik's Cube is a seven-order Rubik's Cube, the Rubik's Cube block 2 with small resistance can be the middle edge block in the outermost circle of the peripheral side block 22c, see Figure 1 and Figure 2 shown.

[0062] 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.
