DESCRIPTION OF EMBODIMENTS
(16) The following further describes the present invention in conjunction with the accompanying drawings and specific embodiments.
(17) As shown in FIG. 1, FIG. 2, and FIG. 12 to FIG. 15, a magnetic levitation magic cube according to the present invention includes edge blocks 11, corner blocks 3 and center blocks 2. Inner sides of two side faces 111 close to the corner blocks (not shown in figures) of the edge block 11 each are provided with three magnet mounting grooves 121. A magnet 14 is mounted in each of the magnet mounting grooves 121. Further, the magnet mounting grooves 121 of each side face 111 of the edge block 11 are arrayed in a triangle pattern, i.e., the magnets 14 are arrayed in the triangle pattern. In particular, the magnet mounting grooves 121 of each side face 111 of the edge block include one primary positioning magnet mounting groove 1211 and two auxiliary decelerating magnet mounting grooves 1212. A movement trajectory of the primary positioning magnet mounting groove 1211 does not coincide with movement trajectories of the auxiliary decelerating magnet mounting grooves 1212. The two auxiliary decelerating magnet mounting grooves 1212 are located on two sides of the primary positioning magnet mounting groove 1211 respectively. Because the edge block can rotate during use of the magic cube, the magnets 14 mounted in the edge block can also rotate along with the edge block. Also, the rotation axis of the edge block is fixed, and thus rotation trajectories of the magnet mounting grooves 121 are fixed. The movement trajectory of the primary positioning magnet mounting groove 1211 does not coincide with the movement trajectories of the auxiliary decelerating magnet mounting grooves 1212, such that the magnets mounted in the auxiliary decelerating magnet mounting grooves 1212 can be staggered from magnets on the corner blocks, thereby assisting in deceleration and also greatly reducing the thrust of start for rotating the stationary magic cube.
(18) As shown in FIG. 2 and FIG. 3, the edge block 11 includes an edge block body 12 and a color sheet 13. An outer end of the edge block body 12 is provided with an opening 122. The color sheet 13 is fastened to the opening 122 of the edge block body 12. The magnet mounting grooves 121 are arranged in positions close to the opening 122 of the edge block body 12. The magnet mounting grooves 121 each abuts against one end of the corresponding magnet 14. An inner surface of the color sheet 13 is provided with inwardly-protruding pressing blocks 131. The pressing blocks 131 each abuts against the other end of the corresponding magnet 14. In the edge block 11, the magnets 14 are placed in the magnet mounting grooves 121 and then pressed by the color sheet 13, which is stable and reliable. The magnets 14 are not attached to an inner wall of the block by glue or other chemical substances, which is safe, environmentally friendly and accurate and reliable in position.
(19) As shown in FIG. 4, the center block of the magic cube based on magnetic levitation repulsive force of the present invention includes a center block body 21 and a center block cover 22. The center block body 21 is a hollow structure and is provided with an opening 211. The center block cover 22 covers and is spliced to the opening 211 of the center block body 21. The center block further includes an upper magnetic disk 23 and a lower magnetic disk 24 that are mounted inside the center block body 21. As shown in FIG. 5, the upper magnetic disk 23 is provided with a through-hole 233 for fastening a central shaft of the magic cube. As shown in FIG. 6, the lower magnetic disk 24 is provided with a through-hole for the central shaft of the magic cube to pass through. An annular magnet 26 is fixedly mounted in each of the upper magnetic disk 23 and the lower magnetic disk 24, and the two annular magnets 26 repel each other.
(20) In particular, the upper magnetic disk 23 includes an adjustment disk 231 and an upper magnetic disk base 232. A lower end face of the adjustment disk 231 is provided with first adjustment teeth 234. An upper end face of the upper magnetic disk is provided with an adjustment tooth surface. A lower end of the upper magnetic disk is provided with a magnet groove for accommodating the corresponding annular magnet. An upper end of the adjustment disk is further provided with a groove 235 capable of driving the adjustment disk to rotate. An outer peripheral edge of the upper magnetic disk base is provided with a side wall 235 capable of driving the upper magnetic disk base to rotate. An upper surface of the adjustment disk 231 is provided with an indication disk. The indication disk is provided with several indication surfaces 236. A width of the indication surface (i.e., a width of a gear indication number in the figure) matches a width of the first adjustment tooth 234, such that the adjustment disk 231 enables an accurate indication when being rotated by a width of one adjustment tooth (i.e., one gear).
(21) As shown in FIG. 7, an inner bottom face of the center block body 21 is provided with a connecting column 212. A circumferential surface of the connecting column 212 is provided with second adjustment teeth 213. As shown in FIG. 8 and FIG. 9, a through-hole of the lower magnetic disk 24 sleeves the connecting column 212. An outer peripheral edge of the through-hole of the lower magnetic disk 24 is provided with third adjustment teeth 241 matching the second adjustment teeth 213. The lower magnetic disk 24 is provided with several sockets capable of driving the lower magnetic disk 24 to rotate. The sockets of the lower magnetic disk 24 are insertion sockets 242 in the peripheral edge of the lower magnetic disk 24. An inner surface of the bottom of the center block body 21 is provided with several indication scale markings 214. The peripheral edge of the lower magnetic disk 24 is provided with several notches 243.
(22) As shown in FIG. 10, the present invention further provides an adjustment tool 25 applied to the center block of the magic cube based on magnetic levitation repulsive force. An end face (a first end in the figure in this embodiment) of the adjustment tool 25 is provided with a sleeve 251 matching a side wall 235 of the upper magnetic disk base 232 in shape. In this embodiment, the side wall 235 defines an octagonal shape, and the sleeve 252 is in an octagonal shape accordingly. During actual implementation, different shapes may be adopted as long as rotation can be realized. Provided is a protrusion 251 matching the groove 235 of the adjustment disk 231 in shape. Due to the structure, after the center block cover 22 of the magic cube is opened, the protrusion/sleeve 251 of the adjustment tool 25 matches the groove/side wall 235 of the adjustment disk 231/upper magnetic disk base 232, and the adjustment disk 231/upper magnetic disk base 232 can be rotated by rotating the adjustment tool 25, thereby adjusting the axis distance.
(23) As shown in FIG. 11, the present invention further provides another implementation of the adjustment tool 25. A peripheral edge of an end of the adjustment tool 25 is provided with several protruding plates 252. In this embodiment, the protruding plates 252 are disposed at the other end different from the protrusion 251. During actual implementation, the two ends can be divided into two tools. A shape of ends of the protruding plates 252 matches a shape of the insertion sockets 242 of the lower magnetic disk 24. A width of an area formed among the protruding plates 252 is larger than a width of the upper magnetic disk 23. When the protruding plates 252 are inserted into the insertion sockets 242 of the lower magnetic disk 24, the adjustment tool 25 can drive the lower magnetic disk 24 to rotate, thereby adjusting a height of the lower magnetic disk 24, a distance between two annular magnets 26, and then the magnitude of magnetic repulsive force.
(24) The foregoing describes only the preferred implementations of the present invention, but is not intended to limit the present invention. Various modifications or variations made to the present invention in practice that do not depart from the spirit and scope of the present invention but fall within the scope of the claims of the present invention and equivalents shall also be included in the present invention.
