A double-layered magic cube

Abstract

This utility model belongs to the field of Rubik's Cube technology and relates to a double-layer Rubik's Cube. The double-layer Rubik's Cube includes an outer layer assembly and an inner layer assembly disposed within and connected to the outer layer assembly. Rotating the outer layer assembly causes the inner layer assembly to rotate, and the rotation of the inner layer assembly in turn adjusts the smoothness of the outer layer assembly's rotation and the accuracy of its return to its original position. The double-layer Rubik's Cube provided by this utility model allows rotation of the outer layer assembly to drive the inner layer assembly's rotation. Furthermore, when the inner layer assembly rotates, its structure in turn adjusts the smoothness of the outer layer assembly's rotation and the accuracy of its return to its original position. In other words, the inner layer assembly effectively improves the smoothness and fluidity of the outer layer assembly's rotation, while also effectively reducing the stuttering that occurs when the outer layer assembly returns to its original position.

Description

Technical Field

[0001] This utility model relates to the field of Rubik's Cube technology, and in particular to a double-layer Rubik's Cube. Background Technology

[0002] A Rubik's Cube is generally composed of multiple edge pieces, corner pieces, and multi-dimensional central axes. Taking the traditional 3x3 Rubik's Cube as an example, its main body has a cube structure, including twenty-six small cubes and a central body. The central body generally has six central axes. The small cubes include six center pieces located at the center of each face of the Rubik's Cube, eight corner pieces located at the corners of the Rubik's Cube, and twelve edge pieces located between adjacent corner pieces. Thus, each face of the Rubik's Cube has nine small cubes. Based on the rotation characteristics of three-dimensional axes, each layer of the Rubik's Cube can be rotated freely.

[0003] Most Rubik's Cubes on the market today consist of a single-layer structure and a central axis. Making the contact area of ​​each piece smaller reduces misalignment during rotation, but also causes the cube to get stuck when turning. Conversely, making the contact area larger reduces stuckness during rotation, but also causes misalignment during rotation. In short, existing Rubik's Cubes cannot simultaneously achieve both smooth rotation and perfect alignment.

[0004] Therefore, there is an urgent need for a product that can solve the above problems at the same time. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that existing Rubik's Cubes cannot simultaneously achieve both stability and spatial error.

[0006] To solve the above-mentioned technical problems, this utility model provides a double-layer Rubik's Cube, which adopts the following technical solution:

[0007] The double-layer Rubik's Cube includes an outer Rubik's Cube component and an inner Rubik's Cube component disposed within and connected to the outer Rubik's Cube component. Rotating the outer Rubik's Cube component causes the inner Rubik's Cube component to rotate. The rotation of the inner Rubik's Cube component is used to reverse the stability of the outer Rubik's Cube component during rotation and the error during return to its original position.

[0008] Optionally, the outer layer Rubik's Cube components include an outer center piece, outer edge pieces, and corner pieces, and the inner layer Rubik's Cube components include an inner center piece and inner edge pieces; wherein,

[0009] The number of outer center blocks: f(n1)1 = 6(n1-2)2;

[0010] The number of outer edge blocks: f(n1)2=12(n1-2), n1≥2;

[0011] Number of corner pieces: 8;

[0012] The number of inner center blocks: f(n2)3 = 6(n2-2)2;

[0013] The number of inner edge blocks is: f(n2)4=12(n2-2), n2≥3; and when n1 is odd, n2=n1, and when n1 is even, n2=n1+1.

[0014] Optionally, the double-layer Rubik's Cube further includes a central axis disposed within the inner layer Rubik's Cube assembly. The central axis contains a plurality of axis modules, the number of which corresponds to the number of outer surfaces of the outer layer Rubik's Cube assembly. Each axis module includes a plurality of axis bodies, and the number of axis bodies in each axis module is the same.

[0015] The total number of shaft bodies is: f(n3)5=6(n3-2)2,n3=n1.

[0016] Optionally, if n1 = 2, each corner block is connected to three adjacent inner edge blocks arranged in three-dimensional directions.

[0017] Optionally, if n1≥3 and n1 is an odd number, each of the outer center blocks and each of the inner center blocks are sleeved on a corresponding shaft body, and each of the outer edge blocks is fixed to a corresponding inner edge block.

[0018] Optionally, if n1≥3 and n1 is an even number, the inner center block and the inner edge block in the middle layer of the inner Rubik's Cube component are fixed relative to the central axis, and the inner center blocks and the outer center blocks of the other layers are all sleeved on a corresponding shaft, and the outer edge blocks are fixed to the other corresponding inner edge blocks.

[0019] Optionally, the outer edge block has a pin hole, and the inner edge block has a positioning pin. The positioning pin is inserted into the pin hole to fix the outer edge block and the inner edge block together.

[0020] Optionally, each side of the inner central block is provided with an inner central magnet;

[0021] Each inner edge block and each side of the adjacent inner center block is provided with an inner edge magnet that attracts the inner center magnet.

[0022] Each of the corner blocks has an extension portion extending toward the center of the central axis, and a first corner magnet that repels the inner central magnet is disposed within the extension portion.

[0023] Optionally, each corner block and each side of the adjacent outer edge block is provided with a second corner magnet, and each outer edge block and each side of the adjacent corner block is provided with an outer edge magnet that attracts the second corner magnet.

[0024] Optionally, the outer center block includes a fixing block and an adjusting member for adjusting the elasticity and axis distance of the double-layer Rubik's Cube. The adjusting member contains a first outer center magnetic ring, and the fixing block contains a second outer center magnetic ring that repels the first outer center magnetic ring. The adjusting member and the fixing block are both sleeved on the shaft body, and the fixing block covers the adjusting member.

[0025] Optionally, the edges of the outer central block are rounded.

[0026] Optionally, the edges of the inner center block are rounded, and the rounded angles of the edges of the outer center block are greater than those of the edges of the inner center block.

[0027] Compared with the prior art, the double-layer Rubik's Cube provided by this utility model has the following advantages:

[0028] The double-layer Rubik's Cube includes an outer Rubik's Cube component and an inner Rubik's Cube component located inside and connected to the outer Rubik's Cube component. Rotating the outer Rubik's Cube component can drive the inner Rubik's Cube component to rotate. When the inner Rubik's Cube component rotates, its own structure can reversely adjust the stability of the outer Rubik's Cube component during rotation and the error rate when returning to its original position. That is, the inner Rubik's Cube component can effectively improve the flow and smoothness of the outer Rubik's Cube component during rotation, and at the same time, it can effectively reduce the jamming phenomenon that occurs when the outer Rubik's Cube component returns to its original position.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. For example, terms such as “length,” “width,” “upper,” “lower,” “left,” “right,” “front,” “rear,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer” indicate orientations or positions based on the orientations or positions shown in the accompanying drawings and are merely for ease of description and should not be construed as limiting the invention.

[0048] The terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this utility model are intended to cover non-exclusive inclusion; the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish different objects, not to describe a specific order. "A plurality of" means two or more, unless otherwise explicitly specified.

[0049] In the description, claims, and accompanying drawings of this utility model, when an element is referred to as "fixed to," "mounted to," "set on," or "connected to" another element, it can be located directly or indirectly on that other element. For example, when an element is referred to as "connected to" another element, it can be directly or indirectly connected to that other element.

[0050] Furthermore, the reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0051] This utility model embodiment provides a double-layer Rubik's Cube 100, such as Figure 1 , Figure 2 , Figure 11 and Figure 12 As shown, the double-layer Rubik's Cube 100 includes an outer Rubik's Cube component 10 and an inner Rubik's Cube component 20. The inner Rubik's Cube component 20 can be disposed inside the outer Rubik's Cube component 10 and connected to it. Understandably, both the outer Rubik's Cube component 10 and the inner Rubik's Cube component 20 are Rubik's Cube structures, meaning they can both rotate according to the Rubik's Cube's trajectory. Rotating the outer Rubik's Cube component 10 can cause the inner Rubik's Cube component 20 to rotate. When the inner Rubik's Cube component 20 rotates, its own structure allows it to simultaneously adjust the stability of the outer Rubik's Cube component 10 during rotation and the accuracy of its return to its original position.

[0052] In summary, compared with existing technologies, this double-layer Rubik's Cube 100 has at least the following beneficial effects:

[0053] When the double-layer Rubik's Cube 100 rotates the outer Rubik's Cube component 10 to drive the inner Rubik's Cube component 20 to rotate, the structure of the inner Rubik's Cube component 20 itself can reverse the stability of the outer Rubik's Cube component 10 during rotation and the error rate when returning to its original position. That is, the inner Rubik's Cube component 20 can effectively improve the process and smoothness of the rotation of the outer Rubik's Cube component 10, and at the same time, it can effectively reduce the stuttering phenomenon that occurs when the outer Rubik's Cube component 10 returns to its original position.

[0054] To enable those skilled in the art to better understand the present invention, the following will be described in conjunction with the appendix. Figures 1 to 12 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0055] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 , Figure 11 and Figure 12 As shown, the outer layer Rubik's Cube component 10 includes an outer center piece 11, an outer edge piece 12, and a corner piece 13, while the inner layer Rubik's Cube component 20 includes an inner center piece 21 and an inner edge piece 22; wherein,

[0056] The number of outer center blocks 11: f(n1)1 = 6(n1-2)2;

[0057] The number of outer edge blocks 12: f(n1)2=12(n1-2), n1≥2;

[0058] Number of corner pieces 13: 8;

[0059] The number of inner center blocks 21: f(n2)3=6(n2-2)2;

[0060] The number of inner edge pieces 22: f(n2)4=12(n2-2), n2≥3; and when n1 is odd, n2=n1, and when n1 is even, n2=n1+1.

[0061] Specifically, if n1 = 2, then the double-layer Rubik's Cube 100 is a 2x2 Rubik's Cube (mainly referring to the outer layer Rubik's Cube component 10 being a 2x2 Rubik's Cube structure), and then combined with... Figure 4 , Figure 11 and Figure 12 The outer layer Rubik's Cube component 10 has the following number of cubes: 11 without outer center pieces, 12 without outer edge pieces, and 8 corner pieces 13; correspondingly, the inner layer Rubik's Cube component 20 has the following number of cubes: 6 inner center pieces 21 and 12 inner edge pieces 22.

[0062] If n1 = 3, then combine Figure 1Diagram and Figure 4 At this time, the double-layer Rubik's Cube 100 is a 3x3 Rubik's Cube (mainly referring to the outer layer Rubik's Cube component 10 being a 3x3 Rubik's Cube structure). The number of cubes in its outer layer Rubik's Cube component 10 are as follows: there are 6 outer center cubes 11, 12 outer edge cubes 12, and 8 corner cubes 13. Correspondingly, the number of cubes in the inner layer Rubik's Cube component 20 are as follows: there are 6 inner center cubes 21 and 12 inner edge cubes 22.

[0063] If n1 = 4, then the double-layer Rubik's Cube 100 is a 4x4 Rubik's Cube (mainly referring to the outer layer Rubik's Cube component 10 being a 4x4 Rubik's Cube structure). The number of cubes in its outer layer Rubik's Cube component 10 are as follows: 24 outer center cubes 11, 24 outer edge cubes 12, and 8 corner cubes 13. Correspondingly, the number of cubes in the inner layer Rubik's Cube component 20 are as follows: 54 inner center cubes 21 and 36 inner edge cubes 22.

[0064] Understandably, as can be seen from the above examples, when the double-layer Rubik's Cube 100 is set as an odd-numbered layer Rubik's Cube (mainly referring to the outer layer Rubik's Cube component 10 being set as an odd-numbered layer Rubik's Cube structure), the number of layers of its inner layer Rubik's Cube component 20 is always one more than the number of layers of the outer layer Rubik's Cube component 10; when the double-layer Rubik's Cube 100 is set as an even-numbered layer Rubik's Cube (mainly referring to the outer layer Rubik's Cube component 10 being set as an even-numbered layer Rubik's Cube structure), the number of layers of its inner layer Rubik's Cube component 20 is the same as the number of layers of the outer layer Rubik's Cube component 10. Furthermore, compared to the outer layer Rubik's Cube component 10, the inner layer Rubik's Cube component 20 removes the "corner piece 13" feature, making the inner layer Rubik's Cube component 20 a spherical Rubik's Cube structure. In addition, the outer layer Rubik's Cube component 10 and the inner layer Rubik's Cube component 20 are located in different orbital planes. Therefore, the inner layer Rubik's Cube component 20 can, by rotating, reverse the smoothness of the rotation of the outer layer Rubik's Cube component 10 and the error during its return to its original position.

[0065] Therefore, it should be noted that the structure of the double-layer Rubik's Cube provided in this embodiment of the present invention is applicable to n-order Rubik's Cubes (n≥20).

[0066] In some embodiments, such as Figure 2 As shown, the double-layer Rubik's Cube 100 also includes a central axis (not shown) disposed within the inner layer Rubik's Cube component 20. The central axis may contain several axis modules (not shown), and the number of axis modules corresponds to the number of outer surfaces of the outer layer Rubik's Cube component 10. Specifically, regardless of the number of layers in the double-layer Rubik's Cube 100, if it is a hexahedron, it has 6 axis modules; if it is an octahedron, it has 8 axis modules, and so on. Each axis module includes several axis bodies 30, and the number of axis bodies 30 in each axis module is the same.

[0067] The total number of shaft bodies 30 is: f(n3)5=6(n3-2)2,n3=n2.

[0068] Specifically, if n1 = 2, the double-layer Rubik's Cube 100 is a second-order Rubik's Cube with no outer center piece 11, 6 inner center pieces 21, and 6 shaft bodies 30. The 6 shaft bodies 30 are respectively set facing the six faces of the outer Rubik's Cube component 10, and each inner center piece 21 is respectively fitted onto a corresponding shaft body 30.

[0069] If n1 = 3, the double-layer Rubik's Cube 100 is a 3x3 Rubik's Cube with 6 outer center pieces 11, 6 inner center pieces 21, and 6 axis bodies 30. The 6 axis bodies 30 are respectively set facing the six faces of the outer Rubik's Cube component 10, and each outer center piece 11 and a corresponding inner center piece 21 are fitted onto the same axis body 30.

[0070] If n1 = 4, the double-layer Rubik's Cube 100 is a 5x5 Rubik's Cube with 24 outer center pieces 11, 54 inner center pieces 21, and 54 axis bodies 30. The six axis modules are respectively set facing the six faces of the outer Rubik's Cube component 10. Each axis module includes nine axis bodies 30, and each outer center piece 11 and a corresponding inner center piece 21 are fitted onto the same axis body 30.

[0071] If n1 = 5, the double-layer Rubik's Cube 100 is a 5x5 Rubik's Cube with 54 outer center pieces 11, 54 inner center pieces 21, and 54 axis bodies 30. The six axis modules are respectively set facing the six faces of the outer Rubik's Cube component 10. Each axis module includes nine axis bodies 30, and each outer center piece 11 and a corresponding inner center piece 21 are fitted onto the same axis body 30.

[0072] As can be understood from the above examples, the total number of shaft bodies 30 of the central shaft is set according to the number of inner central blocks 21.

[0073] In some embodiments, as the first connection method for the cube pieces of the double-layer Rubik's Cube 100, such as Figure 11 and Figure 12 As shown, if n1 = 2, that is, when the double-layer Rubik's Cube 100 is set as a 2x2 Rubik's Cube, each corner piece 13 can be connected to three adjacent inner edge pieces 22 arranged in three-dimensional directions. Specifically, when n1 = 2, there are 12 inner edge pieces 22, and the number of corner pieces 13 is fixed at 8. Based on the aforementioned arrangement, each corner piece 13 is connected to 3 inner edge pieces 22, and each inner edge piece 22 is connected to 2 corner pieces 13. It can be understood that rotating the corner piece 13 causes the inner edge piece 22 connected to it to rotate, and the rotation of the inner edge piece 22 and the inner center piece 21 coordinates the smoothness of the corner piece 13 during rotation and the accuracy of its return to its original position.

[0074] In some embodiments, as a second connection method for the cube pieces of the double-layer Rubik's Cube 100, such as Figure 1 and Figure 2 As shown, if n1≥3 and n1 is an odd number, each outer center block 11 and each inner center block 21 can be fitted onto a corresponding shaft body 30, and each outer edge block 12 can be fixed to a corresponding inner edge block 22. Understandably, the outer center block 11 drives the outer edge block 12 and corner block 13, which are at the same rotational level, to rotate; the rotation of the outer center block 11 also drives the inner center block 21 to rotate, and the rotation of the inner center block 21 and the outer edge block 12 simultaneously drives the inner edge block 22 to rotate. The rotation of the inner center block 21 and the inner edge block 22 works together to regulate the stability of the rotation of the outer center block 11, the outer edge block 12, and the corner block 13, as well as the accuracy of their return to their original positions.

[0075] In some embodiments, as a third connection method for the cube pieces of the double-layer Rubik's Cube 100, if n1≥3 and n1 is an even number, the inner center piece 21 and inner edge piece 22 of the middle layer of the inner Rubik's Cube component 20 can be fixed relative to the central axis. The inner center pieces 21 and outer center pieces 11 of the other layers can be fitted onto a corresponding axis, and the outer edge pieces 12 can be fixed to a corresponding inner edge piece 22. It can be understood that the inner center piece 21 of the middle layer has no corresponding connected outer center piece 11, and the inner edge piece 22 also has no corresponding connected outer center piece 11, and the inner center piece 21 and inner edge piece 22 of this layer are always fixed relative to the central axis. Otherwise, the arrangement of the inner center pieces 21 and inner edge pieces 22 of the other layers is the same as the second connection method, and will not be described further here.

[0076] In some embodiments, based on the second and third connection methods of the cube pieces of the double-layer Rubik's Cube 100, such as Figure 4 , Figure 7 and Figure 8 As shown, the outer edge block 12 may have a pin hole 121, and the inner edge block 22 may have a positioning pin 221. The positioning pin 221 can be inserted into the pin hole 121 to fix the outer edge block 12 and the inner edge block 22 together. Further, the positioning pin 221 can be a cross pin, and the pin hole 121 can be a rectangular hole that matches the cross pin. After inserting the cross pin into the rectangular hole and rotating it 90°, the outer edge block 12 and the inner edge block 22 can be fixedly connected.

[0077] In some embodiments, such as Figure 6 , Figure 7 and Figure 9As shown, each side of the inner center block 21 can be provided with an inner center magnet 211, specifically, each of the four sides of the inner center block 21 can be provided with an inner center magnet 211; each side of the inner edge block 22 that is close to the adjacent inner center block 21 can be provided with an inner edge magnet 222 that attracts the inner center magnet 211, specifically, each inner edge block 22 can be provided with two inner edge magnets 222; each corner block 13 can be provided with an extension portion 131 extending towards the center of the central axis, and a first corner magnet 132 that repels the inner center magnet 211 can be provided in the extension portion 131.

[0078] Understandably, the inner center magnets 211 of the six center pieces repel each other. As the double-layer Rubik's Cube 100 rotates to 0°, the attraction between the inner center magnets 211 of each inner center piece 21 and the inner edge magnets 222 of the inner edge piece 22 gradually decreases, while the repulsive force between the center magnets of the six center pieces gradually increases. This causes the double-layer Rubik's Cube 100 to have a levitation effect during rotation, thereby reducing friction during rotation and resulting in easier rotation and better return to the correct position.

[0079] Each inner center piece 21 and its corresponding inner edge piece 22 are attracted to each other through the inner center magnet 211 and the inner edge magnet 222. The inner edge magnet 222 of the inner edge piece 22 is closer to the center point of the double-layer Rubik's Cube 100, so that the magnets have an overlapping angle during the rotation of the double-layer Rubik's Cube 100, and have a corresponding attraction angle. The first corner magnet 132 on the extension 131 of the corner piece 13 repels the inner center magnet 211 of the inner center piece 21, so that the double-layer Rubik's Cube 100 generates a repulsive force when rotated to 45°, and has a significant return to 0° when rotated between 0-35°, that is, effectively reducing the error when the double-layer Rubik's Cube 100 is in place.

[0080] Furthermore, the diameter of the inner edge magnet 222 can be set to be larger. The inner edge magnet 222 with a larger diameter is closer to the center point of the double-layer Rubik's Cube 100, so that during the rotation of the double-layer Rubik's Cube 100, the overlap angle between the inner edge magnet 222 and the inner center magnet 211 is larger, and the corresponding attraction and return angle is also larger.

[0081] In some embodiments, such as Figure 7 and Figure 9 As shown, each corner piece 13 can have a second corner magnet 133 on each side of its adjacent outer edge piece 12; specifically, each corner piece 13 can have a second corner magnet 133 on each of its three sides. Each outer edge piece 12 can have an outer edge magnet 122 on each side of its adjacent corner piece 13 that attracts the second corner magnet 133; specifically, each outer edge piece 12 can have an outer edge magnet 122 on each of its two sides. Understandably, the attraction between the second corner magnet 133 of each corner piece 13 and the corresponding outer edge magnet 122 of each outer edge piece 12 further improves the placement effect of the double-layer Rubik's Cube 100.

[0082] In some embodiments, such as Figure 10 As shown, the outer center block 11 includes a fixing block 112 and an adjusting member 111 for adjusting the elasticity and axis distance of the double-layer Rubik's Cube 100. The adjusting member may contain a first outer center magnetic ring 1111, and the fixing block 112 may contain a second outer center magnetic ring 1121 that repels the first outer center magnetic ring 1111. Both the adjusting member and the fixing block 112 can be sleeved on the shaft body 30, and the fixing block 112 can cover the adjusting member. Specifically, the first outer center magnetic ring 1111 and the second outer center magnetic ring 1121 repel each other to provide elasticity to the entire double-layer Rubik's Cube 100. Rotating the adjusting member clockwise can adjust the elasticity of the double-layer Rubik's Cube 100, and rotating the adjusting member counterclockwise can adjust the axis distance of the double-layer Rubik's Cube 100.

[0083] In some embodiments, such as Figure 3 and Figure 10 As shown, the edges 113 on each side of the outer center block 11 can be rounded to effectively improve the stability of the double-layer Rubik's Cube 100 when rotating, and ensure a smooth feel when rotating the double-layer Rubik's Cube 100.

[0084] In some embodiments, such as Figure 3 , Figure 6 and Figure 10 As shown, the edges 212 on each side of the inner center block 21 can be rounded; and the rounded angle of the edges 113 on each side of the outer center block 11 can be greater than the rounded angle of the edges 212 on each side of the inner center block 21.

[0085] Understandably, since the outer cube component 10 and the inner cube component 20 are located in different track planes, the rounded corner angles of the edges 113 on each side of the outer center piece 11 are set to be greater than the rounded corner angles of the edges 212 on each side of the inner center piece 21. This provides good fault tolerance for the product. Because the inner cube component 20 has reduced the technical feature of "corner piece 13" compared to the outer cube component 10, the rounded corner angles of the edges 212 on each side of the inner center piece 21 being smaller than the rounded corner angles of the edges 113 on each side of the outer center piece 11 can effectively improve the stability of the double-layer cube 100 when rotating.

Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of the claims of the present invention.
