Description

Technical Field

[0001] The present invention relates to the technical field of Rubik's Cubes, and particularly to a double-layer Rubik's Cube. Background Art

[0002] A Rubik's Cube generally consists of multiple edge pieces, corner pieces and a multi-dimensional central axis. Taking the traditional three-order Rubik's Cube as an example, its main body is in a cube structure, including twenty-six small squares and a central body. The central body generally has six central axes. The small squares include six center pieces respectively located at the center of each face of the Rubik's Cube, eight corner pieces located at the corner parts of the Rubik's Cube, and twelve edge pieces respectively located between adjacent corner pieces. In this way, each face of the Rubik's Cube is nine small squares. Based on the rotational characteristics of the three-dimensional continuous axis, each layer of the Rubik's Cube can rotate freely.

[0003] Most of the common Rubik's Cubes on the market are composed of a single-layer structure and a central axis. If the contact surfaces of the Rubik's Cube blocks of this structure are made smaller, the misalignment phenomenon during the restoration of the Rubik's Cube can be reduced, but at the same time, it will cause jamming when the Rubik's Cube rotates; on the contrary, if the contact surfaces of the Rubik's Cube blocks of this structure are made larger, the jamming phenomenon during the rotation of the Rubik's Cube can be reduced, but at the same time, it will cause misalignment when the Rubik's Cube is restored. In short, the existing Rubik's Cubes cannot simultaneously take into account the problems of smoothness during rotation and misalignment during restoration.

[0004] Therefore, there is an urgent need for a product that can solve the above problems at the same time. Summary of the Invention

[0049] In the description and claims of the present invention and the above-mentioned description of the drawings, when an element is referred to as being "fixed to" or "mounted on" or "disposed on" or "connected to" another element, it can be directly or indirectly located on the other element.

[0050] In addition, the mention of "embodiments" herein means that the specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the present invention.

[0051] An embodiment of the present invention provides a double-layer Rubik's Cube 100, as Figure 1 , Figure 2 , Figure 11 and Figure 12 shown, the double-layer Rubik's Cube 100 includes an outer-layer Rubik's Cube component 10 and an inner-layer Rubik's Cube component 20. The inner-layer Rubik's Cube component 20 can be disposed inside the outer-layer Rubik's Cube component 10 and connected to the outer-layer Rubik's Cube component 10. It can be understood that both the outer-layer Rubik's Cube component 10 and the inner-layer Rubik's Cube component 20 are Rubik's Cube structures, that is, they can both rotate according to the Rubik's Cube movement trajectory. Rotating the outer-layer Rubik's Cube component 10 can drive the inner-layer Rubik's Cube component 20 to rotate, and when the inner-layer Rubik's Cube component 20 rotates, based on its own structure, it can simultaneously and reversely adjust the smoothness during the rotation of the outer-layer Rubik's Cube component 10 and the misalignment during the return.

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

[0053] When the outer Rubik's Cube component 10 is rotated to drive the inner Rubik's Cube component 20 to rotate, the structure of the inner Rubik's Cube component 20 itself can reversely adjust the smoothness of the rotation of the outer Rubik's Cube component 10 and the misalignment during homing, 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 can effectively reduce the jamming phenomenon that occurs when the outer Rubik's Cube component 10 returns to its position.

[0054] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the attached Figures 1 to 12 , drawings.

[0055] In some embodiments, as Figure 1 、 Figure 2 、 Figure 4 、 Figure 11 and Figure 12 shown, the outer Rubik's Cube component 10 includes an outer center block 11, outer edge blocks 12 and corner blocks 13, and the inner Rubik's Cube component 20 includes an inner center block 21 and inner edge blocks 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] The number of corner blocks 13: 8;

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

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

[0061] Specifically, if n1 = 2, at this time the double-layer Rubik's Cube 100 is a second-order Rubik's Cube (mainly referring to the outer Rubik's Cube component 10 having a second-order Rubik's Cube structure), and then combined with Figure 4 、 Figure 11 and Figure 12 , the number of Rubik's Cube blocks of the outer Rubik's Cube component 10 are respectively: no outer center block 11, no outer edge block 12, and the number of corner blocks 13 is 8; correspondingly, the number of Rubik's Cube blocks of the inner Rubik's Cube component 20 are respectively: the number of inner center blocks 21 is 6, and the number of inner edge blocks 22 is 12.

[0062] If n1 = 3, and then combined with Figure 1 、Figure and Figure 4, at this time, the double-layer Rubik's Cube 100 is a three-order Rubik's Cube (mainly referring to the outer Rubik's Cube component 10 having a three-order Rubik's Cube structure). The numbers of Rubik's Cube blocks of the outer Rubik's Cube component 10 are as follows: the number of outer center blocks 11 is 6, the number of outer edge blocks 12 is 12, and the number of corner blocks 13 is 8; correspondingly, the numbers of Rubik's Cube blocks of the inner Rubik's Cube component 20 are as follows: the number of inner center blocks 21 is 6, and the number of inner edge blocks 22 is 12.

[0063] If n1 = 4, at this time, the double-layer Rubik's Cube 100 is a four-order Rubik's Cube (mainly referring to the outer Rubik's Cube component 10 having a four-order Rubik's Cube structure). The numbers of Rubik's Cube blocks of the outer Rubik's Cube component 10 are as follows: the number of outer center blocks 11 is 24, the number of outer edge blocks 12 is 24, and the number of corner blocks 13 is 8; correspondingly, the numbers of Rubik's Cube blocks of the inner Rubik's Cube component 20 are as follows: the number of inner center blocks 21 is 54, and the number of inner edge blocks 22 is 36.

[0064] It can be understood that, as can be seen from the above examples, when the double-layer Rubik's Cube 100 is set as a single-layer Rubik's Cube (mainly referring to the outer Rubik's Cube component 10 being set as a single-layer Rubik's Cube structure), the number of layers of the inner Rubik's Cube component 20 is always 1 more than the number of layers of the outer Rubik's Cube component 10; when the double-layer Rubik's Cube 100 is set as a double-layer Rubik's Cube (mainly referring to the outer Rubik's Cube component 10 being set as a double-layer Rubik's Cube structure), the number of layers of the inner Rubik's Cube component 20 is the same as the number of layers of the outer Rubik's Cube component 10. Moreover, compared with the outer Rubik's Cube component 10, the inner Rubik's Cube component 20 removes the feature of the "corner block 13", making the inner Rubik's Cube component 20 in a spherical Rubik's Cube structure. Coupled with the fact that the outer Rubik's Cube component 10 and the inner Rubik's Cube component 20 are in different orbital plane spaces, therefore, the inner Rubik's Cube component 20 can reversely adjust the smoothness during the rotation of the outer Rubik's Cube component 10 and the spatial error during the homing by rotation.

[0065] Based on this, it should be noted that the structure of the double-layer Rubik's Cube provided by the embodiments of the present invention can be applicable to an n-order Rubik's Cube (n≥20).

[0066] In some embodiments, as Figure 2 shown, the double-layer Rubik's Cube 100 further includes a central axis (not shown in the figure) disposed inside the inner Rubik's Cube component 20. The central axis may include several shaft rod modules (not shown in the figure), and the number of shaft rod modules is set corresponding to the number of outer surfaces of the outer Rubik's Cube component 10. Specifically, regardless of how many layers the double-layer Rubik's Cube 100 has, if it belongs to a hexahedron, 6 shaft rod modules are provided, and if it belongs to an octahedron, 8 shaft rod modules are provided, and so on. Each shaft rod module includes several shaft rod bodies 30, and the number of shaft rod bodies 30 of each shaft rod module is the same. Among them,

[0067] The total number of shaft rod bodies 30: 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 at this time. It has no outer center block 11, 6 inner center blocks 21, and 6 shaft body 30s. The 6 shaft body 30s are respectively arranged towards the six faces of the outer-layer Rubik's Cube component 10, and each inner center block 21 is sleeved on a corresponding shaft body 30.

[0069] If n1 = 3, the double-layer Rubik's Cube 100 is a third-order Rubik's Cube at this time. It has 6 outer center blocks 11, 6 inner center blocks 21, and 6 shaft body 30s. The 6 shaft body 30s are respectively arranged towards the six faces of the outer-layer Rubik's Cube component 10, and each outer center block 11 and a corresponding inner center block 21 are sleeved on the same shaft body 30.

[0070] If n1 = 4, the double-layer Rubik's Cube 100 is a fifth-order Rubik's Cube at this time. It has 24 outer center blocks 11, 54 inner center blocks 21, and 54 shaft body 30s. The 6 shaft modules are respectively arranged towards the six faces of the outer-layer Rubik's Cube component 10. Each shaft module includes 9 shaft body 30s, and each outer center block 11 and a corresponding inner center block 21 are sleeved on the same shaft body 30.

[0071] If n1 = 5, the double-layer Rubik's Cube 100 is a fifth-order Rubik's Cube at this time. It has 54 outer center blocks 11, 54 inner center blocks 21, and 54 shaft body 30s. The 6 shaft modules are respectively arranged towards the six faces of the outer-layer Rubik's Cube component 10. Each shaft module includes 9 shaft body 30s, and each outer center block 11 and a corresponding inner center block 21 are sleeved on the same shaft body 30.

[0072] It can be understood that from the above examples, the total number of the shaft body 30s of the central axis is set according to the number of the inner center blocks 21.

[0073] In some embodiments, as the first connection method of each Rubik's Cube block of the double-layer Rubik's Cube 100, as Figure 11 and Figure 12 shown, if n1 = 2, that is, when the double-layer Rubik's Cube 100 is set as a second-order Rubik's Cube, each corner block 13 can be connected to three inner edge blocks 22 that are arranged in three-dimensional directions and are adjacent to each other. Specifically, when n1 = 2, the number of inner edge blocks 22 is 12, and the number of corner blocks 13 is fixed at 8. Based on the foregoing setting method, each corner block 13 is connected to 3 inner edge blocks 22, and each inner edge block 22 is connected to 2 corner blocks 13. It can be understood that rotating the corner block 13 drives the inner edge block 22 connected thereto to rotate, and the rotation of the inner edge block 22 and the inner center block 21 cooperates to adjust the smoothness when the corner block 13 rotates and the misalignment when it returns to its position.

[0074] In some embodiments, as the second connection method of each magic cube block of the double-layer magic cube 100, as Figure 1 and Figure 2 shown, if n1≥3 and n1 is an odd number, each outer center block 11 and each inner center block 21 can be sleeved on a corresponding shaft body 30, and each outer edge block 12 can be fixed to a corresponding inner edge block 22. It can be understood that the outer center block 11 drives the outer edge block 12 and the corner block 13 in the same rotation layer 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, and the rotation of the inner center block 21 and the inner edge block 22 cooperatively adjusts the smoothness during the rotation of the outer center block 11, the outer edge block 12 and the corner block 13 and the misalignment during the return.

[0075] In some embodiments, as the third connection method of each magic cube block of the double-layer magic cube 100, if n1≥3 and n1 is an even number, the inner center block 21 and the inner edge block 22 in the middle layer of the inner magic cube assembly 20 can be fixedly arranged relative to the central axis, and each inner center block 21 and each outer center block 11 in the remaining layers can be sleeved on a corresponding shaft, and each outer edge block 12 can be fixed to the remaining corresponding inner edge block 22. It can be understood that the inner center block 21 in the middle layer has no corresponding connected outer center block 11, and the inner edge block 22 also has no corresponding connected outer center block 11, and the inner center block 21 and the inner edge block 22 in this layer are always in a fixed state relative to the central axis. In addition, the setting methods of the inner center block 21 and the inner edge block 22 in the remaining layers are the same as those in the second connection method, and will not be elaborated here.

[0076] In some embodiments, based on the second and third connection methods of each magic cube block of the double-layer magic cube 100, as Figure 4 、 Figure 7 and Figure 8 shown, a pin hole 121 can be opened on the outer edge block 12, a positioning pin 221 can be arranged on the inner edge block 22, and the positioning pin 221 can be inserted into the pin hole 121 to fixedly connect the outer edge block 12 and the inner edge block 22. Further, the positioning pin 221 can be a cross pin, and the pin hole 121 can be set as a rectangular hole matching the cross pin of the cross pin. After aligning the cross pin with the rectangular hole and inserting it and then rotating it by 90°, the outer edge block 12 and the inner edge block 22 can be fixedly connected.

[0077] In some embodiments, as Figure 6 、 Figure 7 and Figure 9As shown, inner center magnets 211 can be provided on each side surface within the inner center block 21. Specifically, inner center magnets 211 can be provided on the four side surfaces of the inner center block 21; within each inner edge block 22 and closely attached to each side surface of the adjacent inner center block 21, inner edge magnets 222 that attract the inner center magnets 211 can be provided. Specifically, two inner edge magnets 222 can be provided in the inner edge block 22; an extension portion 131 can be provided by extending each corner block 13 towards the central direction of the central axis, and a first corner magnet 132 that repels the inner center magnet 211 can be provided within the extension portion 131.

[0078] Understandably, there is a repulsive force between the inner center magnets 211 of the 6 center blocks. As the double-layer Rubik's Cube 100 is rotated until it is separated from 0°, the attractive force between the inner center magnets 211 of each inner center block 21 and the inner edge magnets 222 of the inner edge blocks 22 gradually decreases, while the repulsive force of the center magnets of the 6 center blocks gradually increases, causing the double-layer Rubik's Cube 100 to have a floating effect during rotation, thereby reducing the frictional force during rotation and having the effects of easier rotation and better restoration.

[0079] Each inner center block 21 and the corresponding inner edge block 22 attract each other through the inner center magnet 211 and the inner edge magnet 222. The inner edge magnet 222 of the inner edge block 22 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 two magnets have an overlapping angle and a corresponding attractive restoration angle. The first corner magnet 132 on the extension portion 131 of the corner block 13 repels the inner center magnet 211 of the inner center block 21, causing a repulsive force to be generated when the double-layer Rubik's Cube 100 is rotated to 45°, and having an obvious restoration effect of returning to 0° between 0 - 35°, that is, effectively reducing the empty error during the restoration of the double-layer Rubik's Cube 100.

[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 overlapping angle between the inner edge magnet 222 and the inner center magnet 211 is larger, and the corresponding attractive restoration angle is also larger.

[0081] In some embodiments, as Figure 7 and Figure 9 shown, within each corner block 13 and closely attached to each side surface of the adjacent outer edge block 12, second corner magnets 133 can be provided. Specifically, three side surfaces within the corner block 13 can be provided with second corner magnets 133; within each outer edge block 12 and closely attached to the side surface of the adjacent corner block 13, outer edge magnets 122 that attract the second corner magnets 133 can be provided. Specifically, two side surfaces of the outer edge block 12 can be provided with outer edge magnets 122. Understandably, the second corner magnets 133 of each corner block 13 attract the outer edge magnets 122 of the corresponding outer edge blocks 12, which can further improve the restoration effect of the double-layer Rubik's Cube 100.

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

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

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

[0085] It can be understood that since the outer Rubik's Cube component 10 and the inner Rubik's Cube component 20 are in different orbital plane spaces, based on this, setting the rounding angle of the side edges 113 of the outer center block 11 to be greater than the rounding angle of the side edges 212 of the inner center block 21 can provide good fault tolerance for the product. Because the inner Rubik's Cube component 20 reduces the technical feature of the "corner block 13" compared with the outer Rubik's Cube component 10, so setting the rounding angle of the side edges 212 of the inner center block 21 to be smaller than the rounding angle of the side edges 113 of the outer center block 11 can effectively improve the smoothness when the double-layer Rubik's Cube 100 rotates.

[0086] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
