Description

Technical Field

[0001] The utility model relates to the technical field of Rubik's cubes, in particular to a ball shaft assembly and a magnetic Rubik's cube. Background Art

[0002] A traditional Rubik's cube is a six-sided cube made of elastic hard plastic. Its core is a shaft and it consists of twenty-six blocks. The twenty-six blocks include six inner center blocks which are fixed and have only one colored side, eight corner blocks which can rotate, and twelve edge blocks which can also rotate.

[0003] When a traditional Rubik's cube rotates, it depends on the player's precise rotation. Each rotation of the Rubik's cube needs to be 90 degrees so that the Rubik's cube is not easily stuck. For a Rubik's cube with magnetic positioning blocks, there will be a magnetic attraction force that magnetically adsorbs the Rubik's cube in the 90-degree state, and the positioning is more accurate. Most of them have one positioning magnet in the middle of each corner block and edge block, and the positioning is achieved through the adsorption of the positioning magnet.

[0004] However, during the rotation and reset process of the corner block, the magnet inside it will be simultaneously attracted by the magnets inside the two adjacent edge blocks on both sides. The directions of these two attraction forces are opposite, and the attraction forces will cancel each other out, thus affecting the reset of the corner block. Content of the Utility Model

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the defect that during the reset process of the corner block in the prior art, the magnet inside it will be simultaneously attracted by the magnets inside the two adjacent edge blocks on both sides. The directions of these two attraction forces are opposite, and the attraction forces will cancel each other out, thus affecting the reset of the corner block, so as to provide a ball shaft assembly and a magnetic Rubik's cube.

[0006] To solve the above technical problem, the utility model provides a ball shaft assembly, including: a central shaft;

[0007] A bracket, installed on the central shaft. The bracket has two layers of symmetrically distributed magnets. Each layer of magnets has a plurality of magnetic force regions distributed circumferentially. The magnetism of two adjacent magnetic force regions is opposite. One magnetic force region is suitable for magnetic attraction with the corner block, and the other magnetic force region is suitable for magnetic repulsion with the corner block;

[0008] A housing, installed on the central shaft and covering the outside of the bracket.

[0009] Optionally, the bracket includes a first frame body and a second frame body which are detachably connected. The first frame body and the second frame body are respectively provided with a plurality of magnets distributed circumferentially with the axis of the central shaft as the center. The magnetism of two adjacent magnets is opposite.

[0010] Optionally, both the first frame body and the second frame body are in a circular ring structure, and there is a first through hole in the middle for passing through the shaft body of the central axis.

[0011] Optionally, the first frame body and the second frame body are connected by insertion.

[0012] Optionally, the first frame body has a first positioning pin and a first positioning post extending towards the second frame body, the second frame body is provided with a second positioning pin and a second positioning post, the first positioning pin is adapted to be inserted and connected with the second positioning post, and the second positioning pin is adapted to be inserted and connected with the first positioning post.

[0013] Optionally, the two layers of magnets are symmetrically distributed with the axis seat of the central axis as the center.

[0014] Optionally, the bracket has a mounting groove, and the magnet is arranged in the mounting groove.

[0015] Optionally, the outer shell includes a detachable first outer shell and a second outer shell, and the first outer shell and the second outer shell respectively have a second through hole for passing through the shaft body of the central axis.

[0016] Optionally, the first outer shell is provided with a first card slot and a first card board, the second outer shell is provided with a second card slot and a second card board, the first card board is adapted to be inserted into the second card slot, and the second card board is adapted to be inserted into the first card slot.

[0017] A magnetic cube includes: the ball shaft assembly according to any one of the above solutions.

[0018] The technical solution of the present utility model has the following advantages:

[0019] 1. For the ball shaft assembly provided by the present utility model, the bracket has multiple magnetic force areas, and the magnetic forces of two adjacent magnetic force areas are opposite. One magnetic force area is magnetically attracted to the corner block, and the other magnetic force area is magnetically repulsive to the corner block. When the corner block is in a static state, it is attracted to the magnetic force area. When the corner block rotates and resets, it first rotates towards the magnetically repulsive area. At this time, it is subjected to both bidirectional suction forces and a repulsive force. When the corner block moves towards the next magnetically attractive area after passing through the magnetically repulsive area, the direction of the repulsive force changes at this time, which can push the corner block to reset. The repulsive force can offset the reverse suction force received by the corner block, making the reset of the corner block smoother.

[0020] 2. For the ball shaft assembly provided by the present utility model, through the design of the magnetic force area, the rotational resistance during the reset process of the corner block can be greatly reduced, the reset effect of the corner block is better, the user can rotate more easily, and the use experience is better.

[0021] 3. For the ball shaft assembly provided by the present utility model, when the corner block returns to its position, the resistance it encounters becomes smaller. Under the attraction of the next magnetic region, it forms a large-angle automatic return and positioning function, allowing the user not to manually rotate the corner block throughout the process and providing the user with a break time.

[0022] 4. For the magnetic cube provided by the present utility model, since the resistance encountered during the reset process of the corner block becomes smaller and the rotation force is lighter, the magnetic cube operates more smoothly, thereby enhancing the user experience.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] Such as Figures 1 to 3As shown, a specific implementation of the ball shaft assembly provided by this embodiment includes: a central shaft 1, a bracket 2, and a housing 4. The central shaft 1 has six shaft bodies 7 and a shaft seat 13. The bracket 2 is mounted on the central shaft 1. The bracket 2 has two layers of symmetrically distributed magnets 3. Each layer of magnets 3 has a plurality of magnetic force regions distributed circumferentially. The magnetism of adjacent two magnetic force regions is opposite. One magnetic force region is suitable for magnetic attraction with the corner block, and the other magnetic force region is suitable for magnetic repulsion with the corner block. Here, it only refers to the relationship between adjacent two magnetic force regions and the corner block. The housing 4 is mounted on the central shaft 1 and covers the outside of the bracket 2. In this embodiment, the number of magnetic force regions in each layer can be eight, among which four magnetic force regions are positive poles, and the other four magnetic force regions are negative poles. There are magnets 3 inside the corner block. The magnets 3 can be positive poles or negative poles, magnetically attracted to four magnetic force regions and magnetically repelled by the other four magnetic force regions. No matter which face of the Rubik's Cube the corner block rotates, it always moves from the magnetically attracted region towards the magnetically repelled region, and then towards the magnetically attracted region. When moving to the second half, the corner block is simultaneously subjected to suction and repulsion forces, which push the corner block to reset.

[0036] In the ball shaft assembly provided by this embodiment, the bracket 2 has a plurality of magnetic force regions, and the magnetism of adjacent two magnetic force regions is opposite. One magnetic force region is magnetically connected to the corner block, and the other magnetic force region is magnetically repelled by the corner block. When the corner block is in a stationary state, it is magnetically attracted to the magnetic force region. When the corner block rotates and resets, it first rotates towards the magnetically repelled region. At this time, it is subjected to both bidirectional suction forces and a repulsion force. When the corner block moves from the magnetically repelled region towards the next magnetically attracted region, the direction of the repulsion force changes at this time, which can push the corner block to reset. The repulsion force can offset the reverse suction force received by the corner block, making the reset of the corner block smoother.

[0037] As Figure 2 As shown, in the ball shaft assembly provided by this embodiment, the bracket 2 includes a first frame body 5 and a second frame body 6 that are detachably connected. The first frame body 5 and the second frame body 6 are respectively provided with a plurality of magnets 3 distributed circumferentially with the shaft body 7 of the central shaft 1 as the center of the circle. The magnetism of adjacent two magnets 3 is opposite. Specifically, the number of magnets 3 on both the first frame body 5 and the second frame body 6 is eight, totaling sixteen. The magnets 3 are evenly distributed, and the angle between adjacent two magnets 3 is 45 degrees. The volume of each magnet 3 is small, which can not only exert repulsion and attraction on the corner block, but also reduce the amount of material used, thereby reducing the manufacturing cost. Of course, the above description is not restrictive. In some alternative embodiments, the magnets 3 can also be of other shapes. For example, they can be set as circular rings, etc., and are composed of a plurality of magnetic strips spliced together. The magnets 3 are a whole structure.

[0038] As Figure 2As shown in the figure, in the ball shaft assembly provided in this embodiment, both the first frame body 5 and the second frame body 6 are circular ring structures, and there is a first through hole 8 in the middle for passing through the shaft body 7 of the central shaft 1. The space occupied by the circular ring structure is relatively small, which can provide a larger space inside the Rubik's Cube and facilitate the structural design. Of course, the above description is not restrictive. In some alternative embodiments, the first frame body 5 and the second frame body 6 can also be of other shapes. For example, they can be set as ring structures with polygonal shapes, etc.

[0039] As Figure 3 , Figure 4 As shown in the figure, in the ball shaft assembly provided in this embodiment, the first frame body 5 and the second frame body 6 are connected by insertion. The two are connected by insertion, which can ensure that they will not be misaligned and are firmly connected together. Then, by applying pressure to the first frame body 5 and the second frame body 6 through the outer shell 4, the connection of the first frame body 5 and the second frame body 6 can be completed. Of course, the above description is not restrictive. In some alternative embodiments, the first frame body 5 and the second frame body 6 can also be connected by other means. For example, they can be connected by bonding or bolt connection, etc.

[0040] As Figure 3 , Figure 4 As shown in the figure, in the ball shaft assembly provided in this embodiment, the first frame body 5 has a first positioning pin 9 and a first positioning post 10 extending in the direction of the second frame body 6. The second frame body 6 is provided with a second positioning pin 11 and a second positioning post 12. The first positioning pin 9 is adapted to be inserted and connected with the second positioning post 12, and the second positioning pin 11 is adapted to be inserted and connected with the first positioning post 10. The first frame body 5 and the second frame body 6 are inserted into each other, making the connection effect better. Of course, the above description is not restrictive. In some alternative embodiments, the first frame body 5 and the second frame body 6 can also be inserted unidirectionally. For example, only the first positioning pin 9 can be provided on the first frame body 5 and the first positioning post 10 can be provided on the second frame body 6, or only the first positioning post 10 can be provided on the first frame body 5 and the first positioning pin 9 can be provided on the second frame body 6, etc.

[0041] As Figure 2 As shown in the figure, in the ball shaft assembly provided in this embodiment, the two layers of magnets 3 are symmetrically distributed with the shaft seat 13 of the central shaft 1 as the center. The distances between the two layers of magnets 3 and the corner blocks are the same, and the magnetic forces received by each corner block are the same, making the feel better during the rotation of the corner blocks.

[0042] As Figure 2As shown in the figure, in the ball shaft assembly provided in this embodiment, the bracket 2 is provided with a mounting groove 14, and the magnet 3 is arranged in the mounting groove 14. Specifically, the mounting groove 14 is circular, and the magnet 3 is also circular and can be embedded into the mounting groove 14. Multiple sides of the magnet 3 are in contact with the mounting groove 14, so that when the magnet 3 acts on the corner block, its position will not be changed by the reaction force, ensuring the normal operation of the Rubik's Cube. Of course, the above description is not restrictive. In some alternative embodiments, the magnet 3 can also be installed on the bracket 2 in other ways. For example, it can be installed by bonding or the like.

[0043] As Figure 1 、 Figure 5 shown in the figure, in the ball shaft assembly provided in this embodiment, the housing 4 includes a first housing 15 and a second housing 16 that are detachably connected. The first housing 15 and the second housing 16 respectively have a second through hole 17 for passing through the shaft body 7 of the central shaft 1. The first housing 15 and the second housing 16 are both hemispherical. After the two parts are connected, the bracket 2 can be covered inside, which can play a role in pressing the bracket 2.

[0044] As Figure 1 、 Figure 5 shown in the figure, in the ball shaft assembly provided in this embodiment, the first housing 15 is provided with a first card slot 18 and a first card board 19, and the second housing 16 is provided with a second card slot 20 and a second card board 21. The first card board 19 is adapted to be inserted into the second card slot 20, and the second card board 21 is adapted to be inserted into the first card slot 18. The first housing 15 and the second housing 16 are inserted into each other, making the connection effect better. Of course, the above description is not restrictive. In some alternative embodiments, the first housing 15 and the second housing 16 can also be inserted unidirectionally. For example, only the first card board 19 can be provided on the first housing 15 and the first card slot 18 can be provided on the second housing 16, or only the first card slot 18 can be provided on the first housing 15 and the first card board 19 can be provided on the second housing 16, etc.

[0045] In addition, as Figures 1 to 5 shown in the figure, this embodiment also provides a magnetic Rubik's Cube, including: the above-mentioned ball shaft assembly.

[0046] For the magnetic Rubik's Cube provided in this embodiment, since the resistance received during the reset process of the corner block becomes smaller and the rotation force is lighter, the magnetic Rubik's Cube runs more smoothly, thereby improving the user experience.

[0047] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
