Description

Technical Field

[0001] This utility model relates to the field of Rubik's Cube technology, and in particular to an intelligent Rubik's Cube with a modular ball axis structure. Background Technology

[0002] A traditional Rubik's Cube is a six-sided cube made of flexible, hard plastic. At its core is an axis, and it consists of 26 pieces. These include six center pieces, which are fixed and have only one colored face; eight corner pieces; and twelve edge pieces. When sold as a toy, the pieces are arranged so that each face of the cube has the same color. When a face of the cube is rotated, the single color of its adjacent faces is broken, creating a new pattern. This process continues, resulting in a cube where each face is composed of a different color. The goal is to restore the scrambled cube to a single color on all six faces as quickly as possible by rotating it.

[0003] In Rubik's Cube competitions, relatively complex cubes are typically used. During the competition, participants need to rotate the cubes quickly to rearrange them in the shortest possible time. Traditional Rubik's Cubes rely on precise rotations, requiring each rotation to be a 90-degree angle to prevent the cube from getting stuck. However, Rubik's Cubes with magnetic positioning blocks use magnetic attraction to hold the cube at 90-degree angles, resulting in more precise positioning.

[0004] However, existing smart Rubik's Cubes have the following drawbacks:

[0005] (1) Existing smart cubes require multiple PCBs and a large number of electronic components. In a limited space, they occupy most of the space, affecting the overall size of the product, thus increasing production costs and reducing production efficiency.

[0006] (2) Existing smart cubes have a high defect rate due to problems such as unstable welding, falling welding wire, and direct contact between magnets and components during the production process of electronic components. Utility Model Content

[0038] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0039] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0040] like Figures 1 to 16As shown, this utility model provides a smart Rubik's Cube with a modular spherical axis structure, including a spherical axis body 10. The spherical axis body 10 includes a detachable spherical shell 101. Six outwardly protruding central axes 102 are mounted on the spherical shell 101. Radial magnets 103 are mounted on the inner bottom of each central axis 102. A detachably connected first cover 104 and second cover 105 are installed inside the spherical shell 101. The four corners of the outer surface of the first cover 104 and the four corners of the outer surface of the second cover 105 are respectively located at the four corners of the outer surface of the first cover 104 and the four corners of the outer surface of the second cover 105. Each cover 104 and the second cover 105 are provided with a groove for accommodating the axial magnet 106; a space for placing the control component is formed between the first cover 104 and the second cover 105. The control component includes a battery 107, a PCB motherboard 108 and an FPC body 109. The battery 107 is electrically connected to the PCB motherboard 108. The FPC body 109 includes an FPC motherboard 1091 and an L-shaped connecting part 1092. The FPC motherboard 1091 is electrically connected to the PCB motherboard 108 through the L-shaped connecting part 1092.

[0041] In this embodiment, the control component is installed within the accommodating space formed by the first cover 104 and the second cover 105. The battery 107, PCB motherboard 108, and FPC body 109 are fixed within the accommodating space through the cooperative structure of the first cover 104 and the second cover 105, realizing modular installation of the control component and improving production efficiency. The control component uses only one PCB motherboard 108 and one FPC body 109 for control, which not only occupies little space but also greatly reduces production costs. In addition, the axial magnet 106 is wrapped in the groove of the first cover 104 and the second cover 105, and the radial magnet 103 is wrapped in the bottom inner side of the central shaft 102. In this way, neither the axial magnet 106 nor the radial magnet 103 will directly contact the battery 107, PCB motherboard 108, and FPC body 109, which helps to reduce the defect rate.

[0042] In a preferred embodiment, the spherical outer shell 101 is provided with a charging hole, and a charging spring 110 is provided inside the charging hole. The charging spring 110 is electrically connected to the FPC motherboard 1091.

[0043] In this embodiment, the charging spring 110 has a connecting part extending to the second cover 105 and a contact part extending into the charging hole. The connecting part is welded to the FPC motherboard 1091. Charging can be performed by the external charging pin contacting the contact part of the internal charging spring 110.

[0044] In a preferred embodiment, the accommodating space is provided with a flexible board fixing member 111 and a motherboard bracket 112. The flexible board fixing member 111 is connected to the inner side of the second cover 105 and a space for placing the FPC motherboard 1091 is formed between the two. The motherboard bracket 112 is provided with a battery slot for placing the battery 107. The motherboard bracket 112 is electrically connected to the PCB motherboard 108.

[0045] In this embodiment, the battery 107 is placed in the battery slot of the motherboard bracket 112. Since the motherboard bracket 112 is electrically connected to the PCB motherboard 108, it is convenient to quickly connect the battery 107 to the PCB motherboard 108 so that the battery 107 can supply power to the PCB motherboard 108. The FPC motherboard 1091 is fixed by the structure of the flexible board fixing member 111 and the second cover 105 to prevent the FPC motherboard 1091 from shaking, and at the same time optimize the internal layout space.

[0046] In a preferred embodiment, the first cover 104 is provided with a protrusion 1041, and the second cover 105 is provided with a connecting post 1051 extending toward the protrusion 1041. The connecting post 1051 is provided with a connecting hole adapted to the protrusion 1041, and the motherboard bracket 112 is provided with a through hole matching the protrusion 1041. The protrusion 1041 passes through the through hole and is inserted into the connecting hole to realize the detachable connection of the first cover 104 and the second cover 105.

[0047] In this embodiment, the first cover 104 and the second cover 105 are assembled and fixed by interlocking through post holes. The structure is simple and can be easily assembled. At the same time, it can fix the motherboard bracket 112, eliminating the need for parts to fix the motherboard bracket 112 and helping to reduce production costs.

[0048] In a preferred embodiment, the motherboard bracket 112 has a pin 1121 at its bottom, and the PCB motherboard 108 has a socket that matches the pin 1121. The pin 1121 and the socket are inserted into each other to achieve an electrical connection between the motherboard bracket 112 and the PCB motherboard 108. The inner top surface of the second cover 105 has a positioning pin 1052, and the FPC motherboard 1091 has a positioning hole that matches the positioning pin 1052. The positioning pin 1052 and the positioning hole are inserted into each other to fix the FPC motherboard 1091 to the second cover 105.

[0049] In this embodiment, the insertion post 1121 and the insertion hole are connected to each other to realize the electrical connection between the motherboard bracket 112 and the PCB motherboard 108, avoiding the increase in defect rate caused by poor soldering; the FPC motherboard 1091 and the inner cover are pre-fixed by the structure of positioning hole and positioning post 1052, which plays a positioning role for the installation of FPC motherboard 1091. Then, the FPC motherboard 1091 is clamped and fixed by the flexible board fastener 111 to realize the quick installation of FPC body 109.

[0050] In a preferred embodiment, the flexible board fixing member 111 is provided with a snap-fit ​​portion 1110, and the second cover 105 is provided with a snap-fit ​​hole adapted to the snap-fit ​​portion 1110. The snap-fit ​​portion 1110 is engaged with the snap-fit ​​hole to detachably connect the flexible board fixing member 111 and the second cover 105. In this embodiment, the flexible board fixing member 111 and the second cover 105 are detachably connected through the structure of the snap-fit ​​portion 1110 and the snap-fit ​​hole, which has the characteristics of simple structure, convenient assembly, and easy disassembly.

[0051] In a preferred embodiment, a central block 20 is further included, correspondingly mounted on the six central shafts 102. Each central block 20 includes a central seat 201 and a central cover 202. The central seat 201 is hollow and has an opening. The central cover 202 covers the opening of the central seat 201. An upper magnetic disk 203 and a lower magnetic disk 204 are installed inside the central seat 201. An upper magnet 205 and a lower magnet 206 are fixedly installed inside each of the upper magnetic disk 203 and lower magnetic disk 204, and the upper magnet 205 and lower magnet 206 repel each other. The upper magnetic disk 203 includes an adjustment disk 203. 1. A magnetic disk base 2032, wherein the lower end face of the adjustment disk 2031 is provided with a first adjustment tooth, the upper end face of the magnetic disk base 2032 is provided with an adjustment tooth surface, the lower end of the magnetic disk base 2032 is provided with a magnetic groove for accommodating the lower magnet 206, the upper surface of the adjustment disk 2031 is provided with a digital gear 2033; the interior of the center base 201 is provided with a second adjustment tooth, the lower magnetic disk 204 is provided with a third adjustment tooth that matches the second adjustment tooth, the outer periphery of the lower magnetic disk 204 is provided with a plurality of toggle notches 2041, and the upper surface of the lower magnetic disk 204 is provided with an English document position 2042.

[0052] In this embodiment, during actual assembly, it is only necessary to insert the end of the central shaft 102 longitudinally through the central seat 201, then assemble the lower magnetic disk 204 on the central seat 201, place the lower magnet 206 inside the lower magnetic disk 204, place the upper magnet 205 inside the upper magnetic disk 203, and then connect the upper magnetic disk 203 to the end of the central shaft 102. Under the repulsive force between the upper magnet 205 and the lower magnet 206, the upper magnetic disk 203 is suspended. When it is necessary to adjust the wheelbase, it is only necessary to use the adjustment tool to turn the adjustment disk 2031 to adjust the pressure of the upper magnetic disk 203 on the adjustment disk 2031 at different gears, thereby adjusting the wheelbase between the central shaft 102 and the central block 20. When it is necessary to adjust the repulsive force between the upper magnet 205 and the lower magnet 206, simply use an adjustment tool to move the lower magnetic disk 204. The distance between the lower magnetic disk 204 and the upper magnetic disk 203 varies at different settings, thus resulting in different magnitudes of the repulsive force between the upper magnet 205 and the lower magnet 206. This allows for dual adjustment of the distance to the central axis 102 and the magnitude of the elastic force. By using two identical upper magnets 205 and 206, magnetically repulsive and spaced side-by-side, to provide the repulsive force for magnetic levitation, the repulsive force of magnetic levitation becomes more stable, and the installation structure is simplified, improving assembly efficiency.

[0053] The magnetic or spring force adjustment uses an English display, while the wheelbase adjustment uses a digital display, which facilitates precise adjustment of the wheelbase and spring force levels, and greatly improves the convenience and accuracy of adjustment.

[0054] When adjusting the repulsive force or elastic force, simply use an adjustment tool to turn the actuation notch 2041 on the lower magnetic disk 204, causing the lower magnetic disk 204 to rotate. Through the cooperation between the third adjustment tooth of the lower magnetic disk 204 and the second adjustment tooth inside the center seat 201, the overall installation height of the lower magnetic disk 204 changes, thereby changing the distance between the lower magnetic disk 204 and the upper magnetic disk 203. This, in turn, changes the distance between the lower magnet 206 installed in the lower magnetic disk 204 and the upper magnet 205 installed in the upper magnetic disk 203, thus achieving the adjustment of the magnitude of the repulsive force (elastic force).

[0055] When adjusting the wheelbase, simply use the adjustment tool to turn the adjustment disk 2031, causing it to rotate. Through the engagement between the first adjustment tooth on the adjustment disk 2031 and the adjustment tooth surface at the bottom of the magnetic disk base 2032, the wheelbase between the central shaft 102 and the central block 20 can be adjusted at different gear positions.

[0056] In a preferred embodiment, a screw 207 is installed at the end of the central shaft 102, and the head of the screw 207 presses against the upper surface of the adjusting disk 2031. By providing a screw 207 at the end of the central shaft 102, the adjusting disk 2031 can be fixed, preventing the adjusting disk 2031 from flying out during the adjustment process.

[0057] In a preferred embodiment, the system further includes twelve edge blocks 30, each edge block 30 comprising an edge block base 301 and an edge block magnetic chamber 302. Each edge block magnetic chamber 302 contains an edge block magnetic component. The side of the edge block base 301 is provided with a magnetic adjustment groove 303, and the edge block magnetic chamber 302 is slidably connected within the magnetic adjustment groove 303. The side of the edge block base 301 is provided with an edge block magnetic stop 304.

[0058] In this embodiment, by setting a magnetic force adjustment groove 303, the position of the edge block magnetic force chamber 302 can be adjusted, thereby adjusting the position of the edge block magnetic component and changing the magnetic attraction between the edge block 30 and the corner block 40, thus achieving the function of adjustable magnetic force of the edge block 30 without affecting the positioning of the Rubik's Cube.

[0059] In a preferred embodiment, the system further includes eight corner blocks 40, each corner block 40 including a corner block base 401. The corner block base 401 has a corner block magnetic chamber 402 on its side. The corner block magnetic chamber 402 is equipped with a corner block magnetic attractor for attracting the magnetic components of the edge blocks. The corner block base 401 is detachably connected to a corner block magnetic rod 403. The bottom of the corner block magnetic rod 403 is provided with a corner block magnet corresponding to the central magnet 106.

[0060] In this embodiment, by setting corner magnetic rods 403, the corner magnets are prevented from falling off during rotation. At the same time, the magnetic attraction position of corner 40 and central axis 102 is set as low as possible, which increases the rotational torque while reducing the rotational thrust. This changes the traditional Rubik's Cube solving method. The corner magnetic rods 403 and the central magnet 106 attract each other to realize the Rubik's Cube's automatic return and positioning functions.

[0061] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
