Description

Technical Field

[0001] The utility model relates to the technical field of Rubik's cubes, in particular to a Rubik's cube toy with adjustable magnetic force and axle distance. Background Art

[0002] Since the advent of the Rubik's cube, due to its strong educational function for humans, it has once been popular all over the world. The Rubik's cube is easy to understand and has ever-changing flexibility. To play it well, the player must be able to concentrate, keep thinking, and be patient. In a sense, the Rubik's cube has become a special toy for intellectual development and a toy for testing the intelligence level and maturity of the player, thus attracting batch after batch of players. In Rubik's cube competitions, relatively complex Rubik's cubes are usually used as competition props. During the competition, the contestants need to rotate quickly to complete the reordering of the Rubik's cube in the shortest time. For traditional Rubik's cubes, the rotation depends on the accurate rotation of the player, and each rotation of the Rubik's cube needs to be 90 degrees, so that the Rubik's cube is not easily stuck. For Rubik's cubes with magnetic positioning blocks, there will be magnetic attraction to make the Rubik's cube be magnetically adsorbed at the 90-degree state, and the positioning is more accurate. However, the existing magnetic Rubik's cubes have the following defects:

[0003] (1) For some existing magnetic Rubik's cubes, the magnetic absorption structure of the Rubik's cube product is for top surface positioning. Most of them use one positioning magnet in the middle of each corner block and edge block. The magnetic force of the positioning magnet is relatively large, and the starting resistance of the Rubik's cube from static to rotation is relatively large, which is not conducive to quickly restoring the Rubik's cube.

[0004] (2) For some existing magnetic Rubik's cubes, they are equipped with a magnetic positioning device, which is usually a magnet. The whole Rubik's cube needs to be disassembled, and the magnet is pasted on the inner wall of the magnet groove of the block through chemical substances such as glue. Using glue is not only not environmentally friendly, but also has poor assembly accuracy, and it is not easy to replace the magnet, making it difficult to change the magnetic force of the block, and thus difficult to adjust the magnetic force of the layer where the block is located.

[0005] (3) Most of the existing center blocks of Rubik's cubes on the market are used to rotate the Rubik's cube by adjusting the elastic force of the spring. Since the spring is in contact with the center block, the frictional resistance is relatively large, which is not conducive to improving the rotation speed.

[0006] (4) For some existing magnetic Rubik's cubes, there is no obvious reference for adjusting the magnetic force and axle distance of the Rubik's cube on the market, and the adjustment is not convenient and accurate. Content of the Utility Model

[0007] Aiming at the above defects existing in the prior art, the utility model provides a Rubik's cube toy with adjustable magnetic force and axle distance to realize the dual adjustment of magnetic force and axle distance.

[0012] Further, the edge block assembly includes an edge block main body and an edge block cover plate. An edge block magnet is provided at the bottom of the edge block main body. The central block main body is provided with a second central magnet attracting the edge block magnet.

[0013] Further, the corner block magnetic force bin includes a magnetic force bin upper cover and a magnetic force bin lower cover. The corner block magnet is wrapped in a cavity formed by the combination of the magnetic force bin upper cover and the magnetic force bin lower cover. The magnetic force bin upper cover and the magnetic force bin lower cover are welded into one body by ultrasonic welding.

[0014] Furthermore, the wheelbase adjustment assembly includes a wheelbase adjustment disk and a wheelbase digital display disk. A wheelbase gear adjustment stepped bottom tooth is arranged inside the wheelbase adjustment disk, and a wheelbase gear adjustment stepped top tooth is arranged at the bottom of the wheelbase digital display disk. The wheelbase digital display disk is installed inside the wheelbase adjustment disk, and the wheelbase gear adjustment stepped top tooth arranged at the bottom of the wheelbase digital display disk abuts against the wheelbase gear adjustment stepped bottom tooth arranged inside the wheelbase adjustment disk.

[0015] Furthermore, the wheelbase adjustment disk is further provided with a second accommodation groove for accommodating the second magnetic member; a wheelbase gear shifting groove and a shifting indication direction are arranged on the end face of the wheelbase adjustment disk.

A magnetic force gear shifting groove is arranged on the outer edge of the magnetic force adjustment disk, and magnetic force gear display numbers are arranged on the surface of the magnetic force adjustment disk.

[0018] Furthermore, both the first magnetic member and the second magnetic member are annular magnets.

[0019] Compared with the prior art, the beneficial effects of the present utility model at least include:

[0020] The present utility model uses the repulsive force of the mutual repulsion between the first magnetic member and the second magnetic member to replace the elastic force of the spring, so that there is no contact between the center block body and the central shaft in the horizontal direction, greatly reducing the rotation resistance. Through the settings of the wheelbase adjustment assembly and the magnetic force adjustment assembly, precise adjustment of the magnetic force magnitude and wheelbase inside the center block body can be realized to meet the requirements of different players. In addition, both the corner block assembly and the edge block assembly are attracted to the center block body, and the corner block assembly and the edge block assembly enclose the outside of the hemispherical structure and can be rotatably connected to the hemispherical structure, which can reduce the friction between the center block body and the corner block assembly and the edge block assembly, thereby reducing the resistance of the Rubik's Cube rotation and making the rotation smoother.

[0041] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this utility model will be more complete and comprehensive, and will fully convey the concept of the example embodiments to those skilled in the art. Like reference numerals in the figures denote like or similar structures, and thus their repetitive description will be omitted.

[0042] The words expressing positions and directions described in this utility model are all illustrated by taking the accompanying drawings as examples, but can be changed according to needs, and all the changes made are included in the protection scope of this utility model.

[0043] As Figure 1-18 shown, a Rubik's Cube toy with adjustable magnetic force and axial distance provided by this utility model includes a central body 1, a central shaft 2 and two central block assemblies 3. The central body 1 is provided with a transverse shaft hole 11 for the central shaft 2 to pass through. The central block assembly 3 includes a central block main body 31 having a cavity. Two central block main bodies 31 are assembled to form a cube structure 32 and two hollow hemispherical structures 33. The two hemispherical structures 33 are respectively located at the top and bottom of the cube structure 32. The two hemispherical structures 33 are provided with openings. The cube structure 32 has an internal space communicating with the hemispherical structures 33. The central body 1 is located in the internal space. Both of the two central block main bodies 31 are provided with shaft matching parts 310 communicating with the transverse shaft hole 11. The central shaft 2 is inserted into the transverse shaft hole 11 from one of the shaft matching parts 310 and extends out from the other shaft matching part 310 to connect the central block assembly 3 with the central body 1. Four corner block assemblies 4 and four edge block assemblies 5 are arranged on the upper surface and the lower surface of the cube structure 32 respectively. The corner block assemblies 4 and the edge block assemblies 5 are all attracted to the central block main body 31. The corner block assemblies 4 and the edge block assemblies 5 surround the outside of the hemispherical structures 33 and can be rotatably connected with the hemispherical structures 33. A clamping part 21 is provided at the end of the central shaft 2. An axial distance adjusting assembly 6 for adjusting the axial distance is provided at the end of the central shaft 2. The axial distance adjusting assembly 6 is provided with a clamping groove 622 for clamping with the clamping part 21. A magnetic force adjusting assembly 7 for adjusting the magnetic force is sleeved at one end of the shaft matching part 310 close to the axial distance adjusting assembly 6. A first magnetic member 8 is provided on one side of the magnetic force adjusting assembly 7 facing the axial distance adjusting assembly 6. A second magnetic member 9 is provided on one side of the axial distance adjusting assembly 6 facing the magnetic force adjusting assembly 7. The first magnetic member 8 and the second magnetic member 9 repel each other.

[0044] In this embodiment, during actual assembly, only the central shaft 2 needs to penetrate the central block body 31 transversely, then the magnetic force adjustment assembly 7 is assembled on the shaft fitting portion 310, and then the axle distance adjustment assembly 6 is assembled at the end of the central shaft 2. Under the repulsive force between the first magnetic member 8 and the second magnetic member 9, the axle distance adjustment assembly 6 floats, making the installation convenient. When the axle distance needs to be adjusted, the axle distance adjustment assembly 6 is used to adjust the axle distance between the central shaft 2 and the central block body 31. When the repulsive force between the first magnetic member 8 and the second magnetic member 9 needs to be adjusted, the magnetic force adjustment assembly 7 is used to adjust the distance between the first magnetic member 8 and the second magnetic member 9, so that the repulsive force between the first magnetic member 8 and the second magnetic member 9 is different, thereby realizing the adjustment of the magnetic force magnitude.

[0045] In this embodiment, the repulsive force between the first magnetic member 8 and the second magnetic member 9 is used to replace the elastic force of the spring, so that the central block body 31 and the central shaft 2 are completely non-contact transversely, greatly reducing the rotational resistance. Through the settings of the axle distance adjustment assembly 6 and the magnetic force adjustment assembly 7, the precise adjustment of the magnetic force magnitude and the axle distance within the central block body 31 can be realized to meet the requirements of different players. In addition, the corner block assembly 4 and the edge block assembly 5 are both attracted to the central block body 31, and the corner block assembly 4 and the edge block assembly 5 enclose the outside of the hemispherical structure 33 and can be rotatably connected to the hemispherical structure 33, which can reduce the friction between the central block body 31 and the corner block assembly 4 and the edge block assembly 5, thereby reducing the resistance of the Rubik's Cube rotation and making the rotation smoother.

[0046] It can be understood that the central block body 31 of this embodiment is configured with a central block cover plate 34. When the magnetic force and the axle distance need to be adjusted, only the central block cover plate 34 needs to be disassembled, and then the axle distance adjustment assembly 6 and the magnetic force adjustment assembly 7 can be operated.

[0047] As a preferred embodiment, the central body 1 has two non-communicating central cavities 12. The corner block assembly 4 and the edge block assembly 5 both have a rotating portion rotatably connected to the hemispherical structure 33 and a connecting portion connected to the central cavity 12. The rotating portion has an arc surface adapted to the inner spherical surface of the hemispherical structure 33. The connecting portions of the corner block assembly 4 and the edge block assembly 5 both extend into the central cavity 12, and each connecting portion is arranged circumferentially along the central cavity 12.

[0048] In this embodiment, the rotating part of the corner block assembly 4 is the corner block rotating part 410, the connecting part of the corner block assembly 4 is the corner block connecting part 411, the rotating part of the edge block assembly 5 is the edge block rotating part 510, and the connecting part of the edge block assembly 5 is the edge block connecting part 511; the corner block assembly 4 and the edge block assembly 5 are rotatably connected to the hemispherical structure 33 through the rotating part, and the rotating part has an arc surface adapted to the inner spherical surface of the hemispherical structure 33, so that the corner block assembly 4 and the edge block assembly 5 rotate more smoothly. The corner block assembly 4 and the edge block assembly 5 are connected to the central body 1 through the connecting part, preventing the corner block assembly 4 and the edge block assembly 5 from detaching from the central block assembly 3 during rotation.

[0049] As a preferred embodiment, the corner block assembly 4 includes a corner block main body 41 and a corner block cover plate 43. A corner block magnetic force bin 42 is provided at the bottom of the corner block main body 41. A corner block magnet is installed in the corner block magnetic force bin 42, and the central block main body 31 is provided with a first central magnet that attracts the corner block magnet.

[0050] In this embodiment, a groove is provided on the surface of the central block main body 31, and a central block magnetic force bin 35 is provided in the groove. The first central magnet is installed in the central block magnetic force bin 35. When the corner block magnet and the first central magnet attract each other, it assists the Rubik's Cube to automatically return to its original position. Preferably, two corner block magnetic force bins 42 are installed in the corner block main body 41 of this embodiment. Correspondingly, two central block magnetic force bins 35 are also provided.

An edge block magnet 52 is provided at the bottom of the edge block main body 51, and the central block main body 31 is provided with a second central magnet (not shown in the figure) that attracts the edge block magnet 52. The Rubik's Cube is assisted to automatically return to its original position by the attraction between the edge block magnet 52 and the second central magnet.

[0052] As a preferred embodiment, the corner block magnetic force bin 42 includes a magnetic force bin upper cover and a magnetic force bin lower cover. The corner block magnet is wrapped in a cavity formed by the combination of the magnetic force bin upper cover and the magnetic force bin lower cover, and the magnetic force bin upper cover and the magnetic force bin lower cover are integrally welded by ultrasonic welding.

[0053] In this embodiment, the magnetic force bin upper cover and the lower cover are integrally welded by ultrasonic welding, wrapping the magnet therein, reducing the risk of magnet detachment, and greatly improving the reliability of the Rubik's Cube.

[0054] As a preferred embodiment, the wheelbase adjustment assembly 6 includes a wheelbase adjustment disc 61 and a wheelbase digital display disc 62. A wheelbase gear adjustment stepped bottom tooth 610 is provided inside the wheelbase adjustment disc 61, and a wheelbase gear adjustment stepped top tooth 620 is provided at the bottom of the wheelbase digital display disc 62. The wheelbase digital display disc 62 is installed inside the wheelbase adjustment disc 61, and the wheelbase gear adjustment stepped top tooth 620 provided at the bottom of the wheelbase digital display disc 62 abuts against the wheelbase gear adjustment stepped bottom tooth 610 provided inside the wheelbase adjustment disc 61.

[0055] In this embodiment, the wheelbase adjustment disc 61 is toggled by an adjustment tool. By the cooperation between the wheelbase gear adjustment stepped bottom tooth 610 provided inside the wheelbase adjustment disc 61 and the wheelbase gear adjustment stepped top tooth 620 provided at the bottom of the wheelbase digital display disc 62, the wheelbase size between the central shaft 2 and the central block can be adjusted.

[0056] As a preferred embodiment, the wheelbase adjustment disc 61 is further provided with a second accommodation groove 611 for accommodating the second magnetic member 9. An end face of the wheelbase adjustment disc 61 is provided with a wheelbase gear toggle groove 612 and a toggle indication direction 613. Wheelbase gear display numbers 621 are provided on the top surface of the wheelbase digital display disc 62, and the card slot 622 is provided at the center of the wheelbase digital display disc 62. In this embodiment, the setting of the second accommodation groove 611 facilitates the replacement and installation of the second magnetic member 9. By providing the wheelbase gear toggle groove 612, it is convenient to toggle the wheelbase adjustment disc 61 with the aid of an adjustment tool. The design of the wheelbase gear display numbers 621 can visually display the specific wheelbase gear. The wheelbase gear is preferably 6 gears.

[0057] As a preferred embodiment, the magnetic force adjustment assembly 7 includes a magnetic force adjustment disc 71. A magnetic force gear adjustment stepped top tooth 710 is provided at the bottom of the magnetic force adjustment disc 71, and a magnetic force gear adjustment stepped bottom tooth 311 is provided on the periphery of the shaft fitting portion 310. The magnetic force gear adjustment stepped top tooth 710 at the bottom of the magnetic force adjustment disc 71 abuts against the magnetic force gear adjustment stepped bottom tooth 311 provided on the shaft fitting portion 310.

[0058] In this embodiment, when magnetic force needs to be adjusted, the magnetic force adjustment disc 71 is toggled to rotate by an adjustment tool. During the rotation of the magnetic force adjustment disc 71, the magnetic force gear adjustment stepped top tooth 710 will be driven to rotate. Through the cooperation between the magnetic force gear adjustment stepped top tooth 710 and stepped teeth with different heights of the magnetic force gear adjustment stepped bottom tooth 311, the distance between the first magnetic member 8 installed inside the magnetic force adjustment disc 71 and the first magnetic member 8 installed inside the wheelbase adjustment disc 61 is changed, and thus the magnetic force between the first magnetic member 8 and the first magnetic member 8 can be adjusted, so as to realize the adjustment of the magnetic force of the central block assembly 3.

[0060] As a preferred embodiment, the first magnetic member 8 and the second magnetic member 9 are both annular magnets. Of course, the first magnetic member 8 and the second magnetic member 9 can also be magnets of other shapes, such as square or special shapes, as long as the first magnetic member 8 and the second magnetic member 9 repel each other. In addition, this embodiment uses two annular magnets of the same size, which repel each other and are spaced apart from each other to replace the original magnets of different sizes to provide the repulsive force of the magnetic suspension, so that the repulsive force of the magnetic suspension is more stable, and the installation structure is simplified, thereby improving the assembly efficiency.

[0061] The magic cube of the utility model has the following advantages:

[0062] First, the bottom surface of the corner block assembly 4 adopts two corner block magnets to assist the automatic return design; during the rotation process, the corner block magnets on the bottom surface of the corner block assembly 4 and the first center magnet of the center block body 31 attract each other to assist the Rubik's Cube to automatically return to its original position.

[0063] Secondly, by introducing the ultrasonically welded magnetic chamber, the weight of the Rubik's Cube is reduced, making the entire Rubik's Cube lighter, more stable and reliable;

[0064] Thirdly, the wheelbase adjustment component 6 and magnetic force adjustment component 7 of the Rubik's Cube introduce a circular magnet design that is symmetrical up and down, and use the repulsive force of the magnets to replace the elastic force of the spring, so that the center block and the axis are completely non-contact in the horizontal direction, which greatly reduces the rotation resistance of the Rubik's Cube.

[0065] Fourthly, the multi-level adjustment of the magic cube's magnetic force and wheelbase is achieved through 6-speed magnetic force adjustment and 6-speed wheelbase adjustment, which is fully compatible with the magnetic force and wheelbase size changes of each gear, so as to achieve a more suitable magnetic force and wheelbase to meet the needs of various magnetic forces and wheelbases.

[0066] Fifth, both magnetic force adjustment and wheelbase adjustment adopt digital display mode to improve the convenience and accuracy of adjustment.

[0067] Sixthly, the upper cover and the lower cover of the magnetic bin are welded together by ultrasonic welding to wrap the magnets, reducing the risk of the magnets falling off and greatly improving the reliability of the Rubik's Cube.

[0068] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Without departing from the principle and purpose of the present invention, those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
