[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0040] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] like Figures 1 to 6 As shown, this application embodiment provides a smart Rubik's Cube, including: a spherical shell 1, a battery module 2, multiple short axes 3, and multiple blocks. The spherical shell 1 has a cavity and multiple shaft holes 11 connecting the cavities. A circuit assembly 12 and a battery cavity 13 are disposed within the cavity. Multiple orientation sensors are disposed on the circuit assembly 12. The battery module 2 is detachably installed in the battery cavity 13. When the battery module 2 is installed in the battery cavity 13, it is electrically connected to the circuit assembly 12. The short axes 3 have a locking protrusion 331 and a limiting fitting portion. The limiting fitting portion passes through the corresponding shaft hole 11 and is rotatably locked into the shaft hole 11. A magnetic element 321 is disposed on the limiting fitting portion. The magnetic element 321 on each short axis 3 is close to the corresponding orientation sensor on the circuit assembly 12. When the short axis rotates, the magnetic element 321 rotates relative to the orientation sensor, and the orientation sensor can acquire the rotation angle data of the short axis. The detection of rotation angle through the cooperation between the orientation sensor and the magnetic component is a conventional technique in the field, and its principle will not be elaborated upon in this application. Each of the aforementioned blocks is disposed on the periphery of the spherical shell 1, with some blocks (such as the center block) fitted onto the short axis 3 and engaged with the locking protrusion 331 on the short axis 3. In this application, the short axis 3 of the smart cube directly engages with the corresponding block, eliminating the need for screws to fix the blocks and simplifying the assembly structure. The battery module 2 is detachably mounted on the spherical shell 1, facilitating disassembly and replacement and improving energy replenishment efficiency.

[0043] In some possible implementations, each of the blocks includes a central block 4, which includes a main shell 41, an elastic element 42, and a limiting cover 43. The main shell 41 has an inner cavity, the limiting cover 43 is located in the inner cavity, the elastic element 42 is located in the inner cavity, and its two ends abut against the inner wall of the limiting cover 43 and the inner wall of the main shell 41, respectively. One end of the short shaft 3 extends into the inner cavity of the main shell 41 and is engaged with the limiting cover 43 by a latching protrusion 331.

[0044] In some possible implementations, such as Figure 1 As shown, the limiting cover 43 has a central hole, and a clearance notch and a snap-fit ​​groove are respectively provided on the periphery of the central hole. The short shaft 3 passes through the central hole, and the snap-fit ​​protrusion 331 can pass through the clearance notch and be rotatably snapped into the snap-fit ​​groove. The end of the short shaft 3 can smoothly pass through the limiting cover 43 and snap-fit ​​with the limiting cover 43.

[0045] In some possible implementations, such as Figure 6 As shown, the limiting fitting part includes a through section 31 and a limiting section 32. The short shaft 3 includes a main shaft 33. The main shaft 33 and the limiting section 32 are respectively disposed on both sides of the through section 31. The locking protrusion 331 is provided at the end of the main shaft 33 away from the through section 31. The cross-sectional area of ​​the limiting section 32, the through section 31 and the main shaft 33 decreases step by step. The through section 31 passes through the shaft hole 11. The main shaft 33 is located outside the spherical shell 1. The limiting section 32 is limited to the inside of the spherical shell 1.

[0046] In some possible implementations, a convex ring 14 is provided on the outer wall of the spherical shell 1, the convex ring 14 enclosing the shaft hole 11, and a fastening ring 5 is fitted on at least a portion of the convex ring 14. The fastening ring 5 can be an elastic element 42 or a rigid element, which is tightly fitted onto the convex ring 14, so that the convex ring 14 and the inner through section 31 are tightly pressed together, thereby improving the assembly structure stability of the spherical shell 1 and the short shaft 3.

[0047] In some possible implementations, such as Figure 2 As shown, the spherical shell 1 includes two semi-shells 1a, each semi-shell 1a having an opening. Multiple semi-convex rings 141 are provided along the edge of the opening of each semi-shell 1. An integral convex ring 14 is provided on the side of each semi-shell 1 opposite to the opening. The two semi-shells 1a are interlocked, and the opposing semi-convex rings 141 on the two semi-shells 1a are spliced ​​together to form a complete convex ring 14. The fastening ring 5 is sleeved on the two spliced ​​semi-convex rings 141, so that the two semi-convex rings 141 are close together to clamp the inner short shaft 3.

[0048] In some possible implementations, the semi-convex ring 141 includes a central claw 1411 and two arc-shaped segments 1412 located on both sides of the central claw 1411. When the fastening ring 5 is fitted onto the two spliced ​​semi-convex rings 141, the central claw 1411 is engaged with the fastening ring 5, and each central claw 1411 and arc-shaped segment 1412 is tightened inward to fit tightly with the through section 31, thereby improving the assembly structure strength of the short shaft 3.

[0049] In some possible implementations, such as Figure 4 and Figure 5 As shown, the spherical shell 1 has a socket 15 communicating with the battery cavity 13, through which the battery module 2 can be inserted into the battery cavity 13. The smart cube includes a battery cover 16, which is detachably connected to the spherical shell 1 to close or open the socket 15. The battery cover 16 and the spherical shell 1 are connected by fasteners or by a snap-fit ​​structure.

[0050] In some possible implementations, the smart cube includes a frame 17 disposed within the cavity of the spherical shell 1. The frame 17 and the spherical shell 1 can be fixedly connected, such as by snap-fit ​​or fasteners. The frame 17 encloses a flat battery cavity 13. The circuit assembly 12 is disposed on the frame 17 and has two contact springs 121 located on both sides of the battery cavity 13 along its thickness direction. When the battery module 2 is inserted into the battery cavity 13, the two contact springs 121 elastically abut against both sides of the battery module 2 along its thickness direction to electrically connect the battery module 2. The battery module 2 can have a disc-shaped structure, facilitating insertion into or removal from the battery cavity 13.

[0051] The preferred embodiments disclosed above are merely illustrative of this application. These preferred embodiments do not exhaustively describe all details, nor do they limit the application to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this application, thereby enabling those skilled in the art to better understand and utilize this application. This application is limited only by the claims and their full scope and equivalents.
