Referring to fig. 1 to 8, an embodiment of the present application provides a fourth-order magic cube, including: the central body 1, the edge block 3, the corner block 2, the central block 4, the first hidden edge 5 and the second hidden edge 6. The central body 1 is connected with six central shafts 11, the end parts of the central shafts 11 are respectively provided with a central card 12, four first hiding edges 5 are arranged on the periphery of each central card 12, each first hiding edge 5 abuts against a concave surface of the central card 12, and the first hiding edges 5 are provided with first magnetic components 51. The edge blocks 3, the corner blocks 2 and the center blocks 4 are arranged on the periphery side of the center body 1, and the center blocks 4 can be clamped to the first hidden edges 5. The second hidden ribs 6 can be located between two adjacent first hidden ribs 5, the second hidden ribs 6 are provided with second magnetic components 61, and the first magnetic components 51 and the second magnetic components 61 are magnetically attracted. Each first hidden rib 5 abuts against the concave surface of the central card 12, and the central card 12 plays a limiting role on each first hidden rib 5. Under the state that the magic cube resets, the first hidden arris 5 and the second hidden arris 6 are magnetically adsorbed, so that the internal structure of the magic cube is compact and smooth, the hand feeling is more comfortable, and the overall stability is better. In the process of restoring the magic cube, when the outermost color block is close to a reset state, the second hidden edge 6 rotates to be close to the first hidden edge 5, and the magnet on the first hidden edge 5 can generate magnetic attraction force to the corresponding second hidden edge 6, so that the magic cube can be reset quickly.

The assembly structure between the first hidden rib 5 and the second hidden rib 6 of the fourth-order magic cube is a mature prior art, and the assembly relationship of the first hidden rib 5 and the second hidden rib 6 is not changed in the assembly position, but the first magnetic component 51 is arranged on the first hidden rib 5, and the second magnetic component 61 is arranged on the second hidden rib 6.

The four-order magic cube corner block and the edge block are provided with magnets, the magnets on the edge block are attracted with corresponding edge block magnets, and the magnets on the edge block are attracted with adjacent corner block magnets. The multi-channel magnetic attraction structure makes the whole structure of the magic cube compact and smooth.

In one possible embodiment, the first hidden rib 5 has a first tab 52 and a first tab 53, as shown in fig. 3, 4 and 7. The second hidden rib 6 has a second tab portion 62 and a second block portion 63. The first tab 52, the second tab 62 and the center card 12 can be located within the same sphere. The first magnetic member 51 is provided on the first block 53, and the second magnetic member 61 is provided on the second block 63. The first block part 53 and the second block part 63 are both positioned on one side of the magic cube, and the first magnetic component 51 and the second magnetic component 61 are magnetically attracted, so that the internal structure of the magic cube is compact and smooth.

In one possible embodiment, the first magnetic part 51 is disposed at an end face of the first block 53 facing away from the first sheet 52, and the second magnetic part 61 is disposed at an end face of the second block 63 facing away from the second sheet 62. The first block part 53 and the second block part 63 are both positioned on one side of the magic cube, the first magnetic part 51 and the second magnetic part 61 are magnetically attracted, and the internal structure of the magic cube is compact and smooth.

In one possible embodiment, the first block 53 is provided with a support stand 531 and a limit step groove 532. The second block 63 has a first convex portion 631 and a second convex portion 632. The first protruding portion 631 extends to the limit step groove 532, the second protruding portion 632 is limited on a side of the support table 531 away from the first sheet portion 52, the first magnetic component 51 is disposed on the support table 531, and the second magnetic component 61 is disposed on the second protruding portion 632. The limit step groove 532 plays a role in limiting and fixing the first convex portion 631, so that the interior of the magic cube is compact, and the internal structure is prevented from loosening. The second protrusion 632 is limited to the support 531, so that the first magnetic member 51 and the second magnetic member 61 are positioned closer to each other, and the magnetic attraction force is larger.

In one possible embodiment, the support 531 is provided with a mounting groove 5311, and the first magnetic member 51 is embedded in the mounting groove 5311. The mounting groove 5311 has a limiting effect on the first magnetic component 51, and the first magnetic component 51 can be stuck in the mounting groove 5311 through colloid. If the diameter of the first magnetic component 51 is slightly larger than the inner diameter of the mounting groove 5311, the first magnetic component 51 may be embedded in the mounting groove 5311 by interference fit, so as to prevent the first magnetic component 51 from being separated from the mounting groove 5311.

In one possible embodiment, as shown in fig. 5, the mounting groove 5311 has a bottom wall and a peripheral wall, and the bottom wall is provided with a support rib 5312, and the support rib 5312 extends in a direction perpendicular to the bottom wall.

The support rib 5312 supports the first magnetic member 51 accommodated in the installation groove 5311.

In the injection molding process, when the shell of the workpiece is uniform in thickness and density, the injection molded workpiece is attractive in appearance and is not easy to deform. In this embodiment, if the support rib 5312 is not provided, the mounting groove 5311 on the first hidden rib 5 has a large number of solid structures, which results in a large local wall thickness of the workpiece, and thus, the appearance of the housing of the first hidden rib 5 that is injection molded is easy to deform and is not attractive enough. The design of the supporting ribs 5312 is beneficial to the balance of the wall thickness and the uniform density of the shell of the first hidden rib 5, and the injection molded first hidden rib 5 is attractive and is not easy to deform.

In one possible embodiment, referring to fig. 7, the second protrusion 632 has a magnetic cavity therein, and the second magnetic part 61 is mounted in the magnetic cavity. The magnetic force cavity facilitates the installation of the second magnetic part 61 and also plays a role in fixing the second magnetic part 61.

In one possible embodiment, the second hidden rib 6 has a first housing 6a and a second housing, the first housing 6a having a first recess 6a1 and the second housing having a second recess. In a state where the first housing 6a and the second housing are connected, the first recess 6a1 and the second recess are communicated to form the magnetic force chamber. The second magnetic component 61 is mounted in the magnetic cavity, and the magnetic cavity plays a role in limiting the second magnetic component 61, so that the second magnetic component 61 and the first magnetic component 51 are positioned closer.

In one possible embodiment, as shown in fig. 5, 6 and 8, the support 531 has a first abutment wall 5313 facing away from the first tab 52, and the second tab 632 has a second abutment wall 6321. In the state that the fourth-order magic cube is reset, the first attaching wall 5313 can be attached to the second attaching wall 6321. The first magnetic member 51 is disposed on the first attaching wall 5313, and the second magnetic member 61 is disposed on the second attaching wall 6321. The first attaching wall 5313 and the second attaching wall 6321 are tightly attached, and the second magnetic component 61 and the first magnetic component 51 have large magnetic attraction, so that the magic cube has a compact internal structure and more comfortable hand feeling.

In a possible embodiment, the second magnetic members 61 are provided on both sides of the second hidden rib 6, respectively, to magnetically attract the first magnetic members 51 of the two first hidden ribs 5 on both sides of the second hidden rib 6, respectively. The second magnetic parts 61 are respectively arranged on two sides of the second hidden edge 6 and are respectively attracted to the first magnetic parts 51 of the first hidden edges 5 adjacent to the two sides, so that the whole magic cube has compact and smooth structure.

It should be noted that, in the embodiment of the present application, the above limitation on the positional relationship between the first hidden rib 5 and the second hidden rib 6 is the limitation when the magic cube is in the reset state. The reset state refers to a state that the magic cube is in a cube shape as a whole.
