[0074] The restoration-type Rubik's Cube comprises a main shell, six main blocks 3 and a plurality of fixed blocks 4, the six main blocks 3 are respectively arranged along the main shell in the upper, lower, front, rear, left and right directions, and each main block 3 is respectively connected to the main shell; the two ends of the fixed blocks 4 are respectively connected to the adjacent main blocks 3; the assembly block 2 is connected to the three fixed blocks 4, and the corner block 1 is arranged in a one-to-one correspondence with the assembly block 2; in this way, the main shell realizes the installation of the six main blocks 3 and the installation of each fixed block 4, so that the rotation of the blocks is facilitated when the Rubik's Cube is manipulated.

[0075] The three adjacent fixed blocks 4 are arranged in one-to-one correspondence with the X projection slot 21, the Y projection slot 22 and the Z projection slot 23 respectively; the light strip 6 is placed inside the main shell, the main shell has a plurality of shell holes 51, the fixed block 4 has a middle hole 41, the shell hole 51 is arranged directly opposite to the middle hole 41, when the light strip 6 is started, the projected light source passes through the shell hole 51, the middle hole 41 and the assembly block 2 in sequence, and is finally projected on the X block surface 11, the Y block surface 11 and the Z block surface 11; in this way, the light strip 6 is prevented from affecting the rotation of the Rubik's Cube, and at the same time, it is ensured that the light projected by the light strip 6 is projected on the X block surface 11, the Y block surface 11 and the Z block surface 11.

[0076] No matter how the rotating surfaces rotate relative to each other, the shell hole 51 and the middle hole 41 are arranged opposite to each other, or at least switch positions; in this way, it is ensured that the light projected by the light strip 6 is projected on the X block surface 11, the Y block surface 11 and the Z block surface 11.

[0077] The main block 3 has four buckling grooves 31, which are arranged correspondingly up and down and left and right. Buckling parts 42 are respectively formed at both ends of the fixed block 4, and the buckling parts 42 are embedded in the buckling grooves 31 to achieve buckling connection between the main block 3 and the fixed block 4.

[0078] The buckling portion 42 has a raised buckling strip 43 , which is arranged in a long strip shape and is embedded in the buckling groove 31 to achieve buckling of the main block 3 and the fixing block 4 .

[0079] The fixing block 4 includes a snap-fit ​​plate, and two snap-fit ​​parts 42 are respectively connected at both ends of the snap-fit ​​plate, and the snap-fit ​​parts 42 are arranged inclined inwardly; in this way, it is convenient for the snap-fit ​​parts 42 to cooperate with the main block 3, and it is also convenient for the snap-fit ​​strip 43 to be embedded in the snap-fit ​​groove 31, so as to realize the snap connection between the main block 3 and the fixing block 4.

[0080] The buckling strip 43 is arranged in a trapezoidal shape, which facilitates the buckling strip 43 to be inserted into the buckling groove 31 to achieve the buckling connection between the main block 3 and the fixed block 4.

[0081] The middle hole 41 is arranged in a flared shape with a small inside and a large outside, so that light can pass through the middle hole 41 and the light strip 6 can project light onto the block surface 11 .

[0082] The fixing block 4 is arranged in an outwardly arched arc shape, which is convenient for matching with the main housing and increasing the contact area with the main housing, thereby making the rotation more stable.

[0083] The main shell is arranged in a circular shape, and a main cavity is formed inside the main shell. Multiple power modules 7 and multiple light strips 6 are respectively placed in the main cavity; this facilitates the rotation of the Rubik's Cube and the light strips 6 to project light onto each block surface 11.

[0084] The power module 7 includes a motor 71 and a driving gear. The motor 71 is electrically connected to the control chip, and the control chip controls the motor 71 to rotate the driving gear. The power output shaft has an inner end, and the inner end of the power output shaft is connected to the driving gear through a relatively interactive meshing structure. When the torsional force between the power output shaft and the driving gear is less than the slip setting value, the driving gear and the power output shaft rotate synchronously. When the torsional force between the power output shaft and the driving gear is greater than the slip setting value, the power output shaft rotates with slippage relative to the driving gear.

[0085] When the torsional force between the power output shaft and the driving gear is less than the slip setting value, the driving gear rotates synchronously with the power output shaft. When the torsional force between the power output shaft and the driving gear is greater than the slip setting value, the power output shaft rotates with slip relative to the driving gear. In this way, when the Rubik's Cube is controlled to rotate, the motor 71 drives the driving gear to rotate, and the torsional force between the driving gear and the power output shaft is less than the slip setting value. In this way, the power output shaft rotates synchronously with the driving gear, realizing relative rotation of the rotating surfaces.

[0086] When the Rubik's Cube is rotated manually, the motor 71 is in a stopped state, the driving gear is linked with the motor 71 and is also in a fixed state, and the entire polyhedron is rotated manually. At this time, the power output shaft rotates, and as the torque force of the rotation increases to be greater than the slip setting value, the power output shaft and the driving gear slip, thereby ensuring that the polyhedron can still be rotated manually when the motor 71 is stopped.

[0087] Of course, the slip setting value of the torsional force between the power output shaft and the drive gear can be set according to the situation and through the arrangement of the structure.

[0088] The motor 71 has a rotating shaft, and the rotating shaft and the driving gear are linked by a reduction structure 72. In this way, when the Rubik's Cube is rotated by remote control, the rotating shaft of the motor 71 drives the reduction structure 72 to rotate, the reduction structure 72 drives the driving gear to rotate, the driving gear drives the power output shaft to rotate, and the power output shaft drives the rotating surface to rotate. By setting the reduction structure 72, the speed transmission from the rotating shaft to the rotating surface can be reduced to avoid slipping between the driving gear and the power output shaft; when the rotating surface is manually driven to rotate, the reduction structure 72 at this time is reversed to become a speed-increasing structure. As the torsional force between the power output shaft and the driving gear increases until the power output shaft and the driving gear slip, the torsional force transmitted to the motor 71 is greatly reduced to avoid damage to the motor 71.

[0089] The meshing structure has various forms, which can be determined according to actual needs. As a preferred embodiment, the driving gear has a meshing end face facing the inner end of the power output shaft, and the meshing structure includes a meshing groove formed on the meshing end face and a meshing protrusion arranged at the inner end of the power output shaft, and the meshing protrusion is embedded in the meshing groove. In this way, the adjacent friction force between the meshing protrusion and the meshing groove is the above-mentioned slip setting value.

[0090] Alternatively, the meshing protrusion is arranged on the meshing end face of the driving gear, and the meshing groove is arranged on the inner end portion of the power output shaft.

[0091] In order to increase the slip setting value, a friction layer is provided between the outer peripheral surface of the engagement protrusion and the inner side wall of the engagement groove. The friction layer can be elastic or hard.

[0092] As another preferred embodiment, the driving gear has a meshing end face facing the inner end of the power output shaft, the meshing end face is provided with a first meshing tooth, the inner end of the power output shaft is provided with a second meshing tooth, the first meshing tooth is meshed with the second meshing tooth, at this time, the slip setting value can be determined according to the inclination of the first meshing tooth and the second meshing tooth.

[0093] The driving gear has an abutting end face which is opposite to the meshing end face, and an elastic member is provided below the abutting end face, the lower end of the elastic member is fixed, and the upper end of the elastic member abuts against the abutting end face of the driving gear; in this way, when the torsional force between the power output shaft and the driving gear is greater than the slip setting value, the power output shaft squeezes the driving gear to squeeze the elastic member downward, the elastic member is compressed, the power output shaft and the driving gear slip, and the rotation of the manually driven rotating surface is realized.

[0094] The reduction structure 72 is a plurality of nested meshing reduction gears, and the number of reduction stages is determined according to actual needs. The motor 71 is arranged horizontally, and its rotating shaft is connected with a linear gear, which meshes with the reduction gear to change the transmission direction.

[0095] The power module 7 includes a housing, the above-mentioned speed reduction structure 72 and the motor 71 are sealed inside the housing, and the outer end of the power output shaft passes through the housing and extends to the outside of the housing. A central shaft is arranged in the housing, and the above-mentioned driving gear and the power output shaft are sleeved on the central shaft and are rotatably arranged between the central shaft.

[0096] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
