Description

Technical Field

[0001] The utility model relates to the field of magic cubes, in particular to a bipolar magic cube. Background Art

[0002] The SQ1 Rubik's Cube is the most common type of bipolar Rubik's Cube. The SQ1 Rubik's Cube is different from the ordinary Rubik's Cube. The middle layer of the SQ1 Rubik's Cube is two central edges. The existing SQ1 Rubik's Cube has two hemispherical shells with arc-shaped cross-sections arranged on the central edges. The edges and corners of the SQ1 Rubik's Cube are located on both sides of the two central edges.

DETAILED DESCRIPTION

[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0056] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0057] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, 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 a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0058] See also Figures 1 to 12 As shown, the embodiment of the present application provides a bipolar Rubik's Cube, including two central edge blocks 1, a plurality of edge blocks 2 and a corner block 3. The two central edge blocks 1 each have a half track shell 11, and the half track shell 11 includes a main body 111, a first arcuate shell portion 112 and a second arcuate shell portion 113, the first arcuate shell portion 112 is connected to the main body 111 and the concave side of the first arcuate shell portion 112 faces the center of the bipolar Rubik's Cube, the second arcuate shell portion 113 is connected to the first arcuate shell portion 112, and the concave surface of the second arcuate shell portion 113 faces away from the center of the bipolar Rubik's Cube, and the half track shells 11 of the two central edge blocks 1 are spliced ​​to form a complete track shell. Each of the edge blocks 2 and the corner block 3 is located on both sides of the two central edge blocks 1, and each of the edge blocks 2 and the corner block 3 has a track groove 7, and is sleeved on the track shell through the track groove 7, and the second arcuate shell portion 113 and the first arcuate shell portion 112 of the track shell are both located in the track groove 7. The bipolar Rubik's Cube of the patent application has a housing with an "S"-shaped cross section for the sliding track of the multiple edge blocks 2 and the corner blocks 3, and the track grooves 7 of the edge blocks 2 and the corner blocks 3 are also "S"-shaped cross-section track grooves 7 adapted to the "S"-shaped housing. This "S"-shaped matching relationship has a high fault tolerance rate. During the rotation process of the Rubik's Cube, the range of wrong angles and positions that can be tolerated is large, and errors can be automatically corrected during rotation, reducing jams or inconveniences caused by inadequate rotation. It can significantly improve the smoothness and speed of the speed twisting process, making the operating experience better.

[0059] In some possible implementations, the first arc-shaped shell portion 112 and the second arc-shaped shell portion 113 are smoothly transitioned. The center edge block 1 is not prone to jamming during the relative rotation with the edge block 2 and the corner block 3, so that the rotation is smooth and the smoothness and speed of the speed screwing process are not affected.

[0060] In some possible implementations, only one half track shell 11 is provided on the same side of each central edge block 1. The "S"-shaped design of the half track shell 11 of the present application can ensure the stability of connection and relative sliding, so only one half track shell 11 is provided on the same side of a central edge block 1 to ensure the stability of connection and relative sliding, and the probability of jamming etc. in a structure in which only multiple half track shells 11 are provided on the same side of the central edge block 1 is reduced, and the fault tolerance rate is greatly improved.

[0061] In some possible implementations, the track groove 7 and the surface of the edge block 2 or the corner block 3 are connected and transitioned by a smooth arc surface. In this way, when the center edge block 1 rotates relative to the edge block 2 and the corner block 3, when the track groove 7 of the edge block 2 and the corner block 3 passes through the joint of two adjacent half track shells 11, the passing process is smoother and less likely to cause jamming, further improving the fault tolerance of the Rubik's Cube.

[0062] In some possible embodiments, the corner block 3 includes a corner block main shell 31 and a corner block cover 32. The corner block main shell 31 includes a main shell 311 and two exposed shells 312. The main shell 311 includes a bottom shell 3111 and a side shell frame 3112 arranged at the edge of the bottom shell 3111. Two side notches are formed on the side shell frame 3112. The two exposed shells 312 are both clamped to the side shell frame 3112. The two exposed shells 312 cover the corresponding side notches respectively. A top opening is formed between the main shell 311 and the two exposed shells 312. The corner block cover 32 is connected to the main shell 311 and / or the exposed shell 312, and the corner block cover 32 covers the top opening. Such a setting method is convenient to install, and it is convenient to set the corner block cover 32, the exposed shell 312 and the main shell 311 as modules of different colors, produce them separately, and then assemble them, which is conducive to large-scale modular production and improves production efficiency.

[0063] In some possible implementations, the side shell frame includes a side main board 31121 and a vertical rib 31122. The side main board 31121 and the vertical rib 31122 are both connected to the bottom shell 3111, and two side notches are formed between the side main board 31121 and the vertical rib 31122. The two sides of the exposed shell 312 are respectively clamped to the vertical rib 31122 and the side main board 31121. The vertical rib 31122 located at the edge is matched with the side main board 31121, and then connected to the outer shell on both sides. Both sides of the exposed shell 312 have a connection structure, which can improve the connection stability of the exposed shell 312 and prevent the exposed shell 312 from falling off during use.

[0064] In some possible implementation schemes, the side main board 31121 is provided with a first clip 311211 on one side of the side notch, and the vertical clip 31122 includes two second clips 311221. The two second clips 311221 are vertically connected, and the two sides of the exposed shell 312 are respectively provided with slide grooves 3121, and the slide grooves 3121 on the two sides of the exposed shell 312 are respectively sleeved on the first clip 311211 and the second clip 311221. When the exposed shell 312 is installed on the main shell 311, the first clip 311211 and the second clip 311221 are respectively inserted into the two slide grooves 3121 from the side away from the bottom shell 3111, and the exposed shell 312 is pushed to a position fitting the bottom shell 3111 along the first clip 311211 and the second clip 311221. This plug-in type of clamping method has a long limit length, good connection stability, and is not easy to shake.

After the cover is firmly inserted, the exposed shell 312 can be limited to prevent the exposed shell 312 from slipping off.

[0066] In some possible embodiments, the edge block 2 includes an edge block main shell 21 and an edge block cover sheet 22. The edge block main shell 21 includes an edge block main shell 211 and an edge block exposed shell 212. The edge block main shell 211 includes an edge block bottom shell 2111 and an edge block side shell frame 2112 arranged at the edge of the edge block bottom shell 2111. A notch is formed on the edge block side shell frame 2112. The edge block exposed shell 212 is clamped to the edge block side shell frame 2112. The edge block exposed shell 212 covers the edge block side notch. A top opening of the edge block is formed between the edge block main shell 211 and the edge block exposed shell 212. The edge block cover sheet 22 is connected to the edge block main shell 211 and / or the edge block exposed shell 212, and the edge block cover sheet 22 covers the top opening of the edge block. This arrangement is convenient for installation and makes it easy to set the edge block cover 22, the edge block exposed shell 212 and the edge block main shell 211 as modules of different colors, produce them separately and then assemble them, which is conducive to large-scale modular production and improves production efficiency.

[0067] In some possible implementation schemes, the edge block side shell frame 2112 is provided with two third clamping ribs 21121 on both sides of the edge block side notch.

[0070] In some possible implementations, the bipolar Rubik's Cube further includes a central body 6, a plurality of first magnetic components 41 are arranged on the central edge block 1, and a second magnetic component 42 is arranged on each of the edge blocks 2 and the corner blocks 3. The first magnetic components 41 on each edge block 2 and the corner block 3 on the same side of the central edge block 1 are located on the first circular trajectory, and the central angle corresponding to the arc line between two adjacent second magnetic components 42 on the first circular trajectory is 30°. The outer structure of the bipolar Rubik's Cube can rotate 30° every time so that each first magnetic component 41 is respectively opposite to the corresponding second magnetic component 42 and magnetically attracts each other. The second magnetic component 42 on an edge block 2 and the second magnetic component 42 on an adjacent corner block 3 are a group, and the first magnetic component 41 on a central edge block 1 can correspond to any group of second magnetic components 42. The mutual attraction between the two magnetic components makes the Rubik's Cube rotation, especially the homing process, have a better feel and a better positioning effect, thereby increasing the speed of the race. Preferably, there is one first magnetic component 41 on the edge block 2 , two first magnetic components 41 on the corner block 3 , and three second magnetic components 42 on the center edge block 1 .

[0071] In some possible implementation schemes, a plurality of third magnetic components 43 are provided on the central body 6, and a fourth magnetic component 44 is provided on each of the edge blocks 2 and the corner blocks 3. The fourth magnetic components 44 on each edge block 2 and the corner block 3 on the same side of the central edge block 1 are located on the second circular trajectory, and the central angle corresponding to the arc line between two adjacent fourth magnetic components 44 on the second circular trajectory is 30°. The outer structure of the bipolar Rubik's Cube can rotate 30° every time so that each third magnetic component 43 is positioned opposite to the corresponding fourth magnetic component 44, and is magnetically attracted to each other. The fourth magnetic component 44 on an edge block 2 and the fourth magnetic component 44 on an adjacent corner block 3 are a group, and the third magnetic component 43 on a central body 6 can correspond to any group of fourth magnetic components 44. The mutual attraction between the two magnetic components further makes the Rubik's Cube rotation, especially the homing process, have a better feel and a better positioning effect, thereby increasing the speed of the race.

[0072] In some possible implementations, the bipolar Rubik's Cube includes a connecting member, an adjusting member 52, a movable member 53 and an elastic member 54, and the bottom wall of the central edge block 1 is provided with a first gear tooth ring 12.

The elastic member 54 is located between the movable member 53 and the adjusting member 52, and the two ends of the elastic member 54 are respectively pressed against the movable member 53 and the adjusting member 52, and the spacing between the adjusting member 52 and the movable member 53 can be adjusted by rotating the adjusting member 52 to compress or release the elastic member 54. When the Rubik's Cube needs to adjust the elastic force, open the cover and directly twist the rotating inner shell to make the upper and lower adjustment ratchets of different heights engage, thereby adjusting the position of the rotating inner shell in the central shell, and then adjusting the distance between the bottom surface of the central shell and the head of the connecting rod to achieve different degrees of elastic compression of the spring to obtain the required elastic force. The operation is simple and convenient. This adjustment method is widely used in the Rubik's Cube, and the structural methods are very mature, so it will not be described here.

[0073] It should be noted that the bipolar Rubik's Cube of the present application can be the SQ1 Rubik's Cube. The SQ1 Rubik's Cube is a mature prior art, and the present application adds the above features on the basis of the existing SQ1 Rubik's Cube to improve the performance of the Rubik's Cube.
