[0046] This embodiment provides a magic cube, such as Figures 1 to 7 As shown, the Rubik's Cube includes an axis seat 100, multiple center axes 200, multiple brush pieces 600, multiple antennas, multiple center block assemblies 300, multiple edge block assemblies 400 and multiple corner block assemblies 500; the multiple center block assemblies 300 include a center block 310, the center block 310 is connected to the end of the center axis 200, and the center block 310 corresponds to the center axis 200 one by one; the multiple edge block assemblies 400 include edge blocks 410, and the edge blocks 410 are arranged adjacent to the center blocks 310; the multiple corner block assemblies 500 include corner blocks 510, and the corner blocks 510 are arranged adjacent to the edge blocks 410.

[0047] The shaft seat 100 includes a shell 110 and a plurality of circuit boards 120 arranged inside the shell 110, and the plurality of circuit boards 120 are spliced ​​to form a polyhedron; a first conductive area 121 and a plurality of second conductive areas 122 are arranged on the outer surface of the circuit board 120; one end of the central axis 200 is installed inside the shell 110, and the other end extends to the outside of the shell 110; the brush sheet 600 includes a fixing portion 610, a first pin 620 and a second pin 630 fixed to the fixing portion 610, the fixing portion 610 is fixed to the central axis 200, and the first pin 620 is electrically connected to the first conductive area 121; the central axis 200 can rotate along the direction of its own axis, so that the second pin 630 is electrically connected to the corresponding second conductive area 122 in sequence.

[0048] Through multiple central block components 300, multiple edge block components 400 and multiple corner block components 500, each face of the Rubik's Cube is evenly divided into multiple layer structures in the vertical and horizontal directions, and each layer structure can rotate freely; through the rotation of each layer structure, the relative positions of the corner blocks 510, the edge blocks 410 and the central block 310 are changed; by rotating the layer structure, the corresponding central axis 200 rotates, the Rubik's Cube switches to a different state, and the brush 600 rotates accordingly, so that the second pin 630 of the brush 600 is electrically connected to different second conductive areas 122 in turn; the second pin 630 is connected to different second conductive areas 122, and can transmit different electrical signals. The electrical signal can be transmitted to an external device through an antenna, thereby transmitting the state of the Rubik's Cube to the external device.

[0049] In some embodiments, a gyroscope may be disposed inside the housing 110 , and the position of the Rubik's Cube may be detected by the gyroscope, and the position of the Rubik's Cube may be transmitted to an external device via an antenna.

[0050] like Figures 8 to 10 As shown, in some embodiments, the first conductive region 121 is annular, the second conductive region 122 is fan-shaped, and multiple second conductive regions 122 are spaced apart in the circumferential direction of the first conductive region 121, so that when the central axis 200 rotates, the first pin 620 can maintain contact with the first conductive region 121, and the second pin 630 can be electrically connected to different second conductive regions 122 in sequence.

[0051] It can be understood that a first conductive area 121 is arranged on the outer surface of each circuit board, and the first conductive area 121 is a circular copper foil at the center of the circuit board 120, and the second conductive area 122 is four arc-shaped copper foils with a common center and equal radius arranged at equal intervals on the periphery of the circular copper foil, and the circular copper foil and the arc-shaped copper foil have a common center; in order to power the main control chipset, a battery is also arranged inside the shell 110, and the battery is electrically connected to multiple circuit boards.

[0052] like Figure 1As shown, in some embodiments, the Rubik's Cube is a polyhedron, and in the extension direction of the edges of the Rubik's Cube, the lengths of the corner block faces of the corner blocks 510 adjacent to the same edge block in the same plane are different. For example, in the same plane, the lengths of the two first outer edges 511 adjacent to the edge 411 and on the same straight line as the edge 411 are different.

[0053] In the initial state of the Rubik's Cube, the Rubik's Cube is a regular polyhedron; in the extension direction of the edges of the Rubik's Cube, the lengths of the corner blocks 510 adjacent to the same edge block in the same plane are different. After the Rubik's Cube is disrupted by rotating one of the layer structures, since the center block 310 is the rotation center, the longer corner block 510 will protrude from one side of the Rubik's Cube, making the Rubik's Cube as a whole form an irregular shape; in the process of rotating the Rubik's Cube, the user can distinguish different corner blocks 510 by the lengths of different corner blocks 510, without identifying the colors of different corner blocks 510, and the operability is strong.

[0054] For the sake of convenience, unless otherwise specified, the structure and form of the Rubik's Cube described in this article refers to the Rubik's Cube in its initial state (such as Figure 1 The structure and form of the Rubik's Cube are shown in FIG. 1 . The Rubik's Cube is a regular polyhedron in the initial state. The layer structure of the Rubik's Cube in the initial state is rotated to change the Rubik's Cube into a scrambled state. Since the lengths of the corner blocks 510 adjacent to the same edge block in the same plane are different in the extension direction of the Rubik's Cube's edges, the scrambled state of the Rubik's Cube is an irregular shape. In this state, the surface of the Rubik's Cube has protrusions or depressions. The user can quickly determine the initial position of the corner block 510 by the length of the different corner blocks 510, which is more conducive to operation. In other words, during use, the user can determine the lengths of different corner blocks 510 by touching them with his hands, and then identify different corner blocks 510, so as to achieve the purpose of blind play.

[0055] Taking the Rubik's Cube 3x3 as an example, the Rubik's Cube has six faces and twelve edges. There are two corner blocks 510 located on the same edge. The two corner blocks 510 have different lengths in the extension direction of the Rubik's Cube's edges. When the Rubik's Cube is scrambled, the longer corner block 510 will protrude from one face of the Rubik's Cube, thereby more intuitively showing the state of the Rubik's Cube.

[0056] like Figure 1As shown, in some embodiments, along the extending direction of the edge of the Rubik's Cube, the length of the edge block 410 is greater than the length of one of the adjacent corner blocks 510, and less than the length of another adjacent corner block 510, so that along the extending direction of the edge of the Rubik's Cube, the lengths of the corner block 510, the edge block 410, and the corner block 510 are successively increased, so as to make the shape of the corner block 510 closer to a tetrahedron as much as possible, so that the Rubik's Cube as a whole has a better sense of order. For example, the lengths of the corner block 510, the edge block 410, and the corner block 510 arranged in sequence along the edge in the extending direction of the edge are: 14 cm, 18 cm, and 22 cm respectively.

[0057] In some embodiments, Figure 2 As shown, the lengths of the central axes 200 are different, which is conducive to adjusting the lengths of different corner blocks 510 so that the lengths of different corner blocks 510 are different.

[0058] In some embodiments, Figure 1 As shown, the lengths of the same corner block 510 in the extension directions of different edges of the Rubik's Cube are all different, which increases the complexity of the Rubik's Cube, multiplies the difficulty of playing, and improves the puzzle's educational value.

[0059] In some embodiments, different edge blocks 410 have the same length; that is, the edge lengths of different edge blocks 410 are all the same, so that the exposed side of the center block 310 can be square, which facilitates the rotation of the center block 310.

[0060] In some embodiments, Figure 4 and Figure 5 As shown, the edge block assembly 400 also includes a first magnet 414, which is arranged inside the edge block 410; the corner block assembly 500 also includes a second magnet 516, which is arranged inside the corner block 510; the first magnet 414 and the second magnet 516 are magnetically attracted to each other, and the attraction of the first magnet 414 and the second magnet 516 makes it easier for adjacent corner blocks 510 and edge blocks 410 to fit together, thereby avoiding the misalignment of different layer structures during the rotation of the layer structure as much as possible, thereby improving the user experience.

[0061] In some embodiments, Figure 6As shown, the edge block 410 includes an edge block cover 412 and an edge block body 413, wherein the edge block cover 412 is covered on the edge block body 413; the edge block body 413 has a first groove 413a, and the first groove 413a is provided with a first mounting groove 413b of the first magnet 414 facing the side wall of the corner block 510, and the first mounting groove 413b can limit the first magnet 414, and avoid the misalignment of the first magnet 414 as much as possible, so as to ensure that the relative position of the first magnet 414 and the edge block 410 remains unchanged. The edge block cover 412 is convenient for installing the first magnet 414, and the first magnet 414 can be installed by simply removing the edge block cover 412 from the edge block body 413. In some embodiments, two first magnets 414 are generally provided in the first groove 413a, and the first groove 413a has two first mounting side walls arranged opposite to each other, and the first mounting side wall is provided with a first mounting groove 413b.

[0062] In some embodiments, the edge block assembly 400 further includes an edge block corner 415 and a third magnet 416. The edge block corner 415 is provided with a first fixing groove for the third magnet 416. The edge block corner 415 serves to limit the edge block 410. Through the first fixing groove, the third magnet 416 can be limited to avoid misalignment of the third magnet 416 as much as possible.

[0063] In some embodiments, the corner block 510 includes a corner block cover 512 and a corner block body 513, wherein the corner block cover 512 is covered on the corner block body 513; the corner block body 513 has a second groove 513a, and the second groove 513a has a second mounting groove 513b for the second magnet 516 on the side wall facing the edge block 410. The second mounting groove 513b can limit the second magnet 516, and avoid the misalignment of the second magnet 516 as much as possible, so as to ensure that the relative position of the second magnet 516 and the corner block 510 remains unchanged. The corner block cover 512 is convenient for installing the second magnet 516, and the second magnet 516 can be installed by simply removing the corner block cover 512 from the corner block body 513. In some embodiments, a second magnet 516 is generally arranged in the second groove 513a, and the second groove 513a has two second mounting side walls arranged opposite to each other, and the second mounting side walls are provided with the second mounting groove 513b.

[0064] In some embodiments, the corner block assembly 500 further includes a corner block clamp 514 and a fourth magnet 515, wherein the corner block clamp 514 is provided with a second fixing slot for the fourth magnet 515; an axis magnet 130 corresponding to the fourth magnet 515 is installed in the housing 110, the third magnet 416 has opposite magnetic properties to the axis magnet 130, and the fourth magnet 515 attracts the axis magnet 130, so as to facilitate the resetting of the corner block 510; for example, when two adjacent layer structures are rotated to 45 degrees relative to each other, since the third magnet 416 has opposite magnetic properties to the axis magnet 130, the two layer structures are forced to continue to rotate to the correct angle, and the fourth magnet 515 attracts the axis magnet 130, so that the corner blocks 510 of the two adjacent layer structures correspond to each other. The corner block clamp 514 plays a role in limiting the corner block 510, and through the second fixing slot, the fourth magnet 515 can be limited to avoid the dislocation of the fourth magnet 515 as much as possible.

[0065] In some embodiments, the center block assembly 300 further includes a spring 312 and a shaft lock 313. A fourth slot 311 is formed inside the center block 310. The spring 312 and the shaft lock 313 are disposed inside the fourth slot 311.

The shaft lock 313 is used to connect the center shaft 200, and the elastic force of the spring 312 makes the magic cube feel better.
