[0031] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0032] See Figures 1 to 6 The four-axis intelligent coding Rubik's Cube shown includes a ball axis 1, corner pieces 2, center pieces 3, and edge pieces 4. The ball axis 1 has four rotating shafts 5. The corner pieces 2 are rotatably mounted on the ends of the rotating shafts 5. The center pieces 3 are rotatably mounted on the rotating shafts 5. The edge pieces 4 can be rotatably arranged between the center pieces 3 on two adjacent rotating shafts 5 around any one of the rotating shafts 5.

[0033] Specifically, a Rubik's Cube spindle includes a spherical shell 1a and a spherical core 1b fixedly disposed within the spherical shell 1a, with a connecting cavity formed between the spherical shell 1a and the spherical core 1b for connecting the spindle 5.

[0034] The rotating shaft 5 includes an inner shaft core 5a and an outer shaft sleeve 5b sleeved outside the inner shaft core 5a. The inner shaft core 5a has a lower pressure plate 5a1 located within the connecting cavity, abutting against the ball core 1b, and rotatable relative to the ball core 1b. The outer shaft sleeve 5b has an upper pressure plate 5b1 located within the connecting cavity, abutting against the ball shell 1a, and rotatable relative to the ball shell 1a. The rotating shaft 5 also includes a double-sided brush plate circuit board 5c sleeved on the inner shaft core 5a and located between the upper pressure plate 5b1 and the lower pressure plate 5a1. An upper brush plate 5b2 electrically connected to the double-sided brush plate circuit board 5c is fixed to the bottom of the upper pressure plate 5b1, and a lower brush plate 5a2 electrically connected to the double-sided brush plate circuit board 5c is fixed to the top of the lower pressure plate 5a1. The rotating shaft 5 is formed by the outer shaft sleeve 5b sleeved on the inner shaft core 5a. The inner shaft core 5a is connected to the corner block 2. When the corner block 2 is rotated, the inner shaft core 5a is driven to rotate, causing the lower brush plate 5a2 to rotate relative to the double-sided brush plate circuit board 5c, thereby recording the rotation information of the corner block 2. The outer shaft sleeve 5b is connected to the center block 3. When the center block 3 is rotated, the outer shaft sleeve 5b is driven to rotate, causing the upper brush plate 5b2 to rotate relative to the double-sided brush plate circuit board 5c, thereby recording the rotation information of the center block 3.

[0035] The inner shaft core 5a has a first connecting portion 5a3 located outside the spherical shell 1a and extending through the outer bushing 5b for connection with the corner block 2. The first connecting portion 5a3 has a first circumferential limiting structure, and the corner block 2 has a first irregular through hole 2a1 that mates with the first circumferential limiting structure. Through the engagement of the first circumferential limiting structure on the first connecting portion 5a3 and the first irregular through hole 2a1 in the corner block 2, circumferential locking between the corner block 2 and the inner shaft core 5a is achieved, that is, rotational synchronization between the corner block 2 and the inner shaft core 5a is achieved.

[0036] The outer bushing 5b has a second connecting portion 5b3 located outside the spherical shell 1a for connection with the central block 3. The second connecting portion 5b3 has a second circumferential limiting structure, and the central block 3 has a second irregularly shaped through hole 3a that mates with the second circumferential limiting structure. By cooperating with the second irregularly shaped through hole 3a in the central block 3, the circumferential locking between the central block 3 and the outer bushing 5b is achieved, that is, the rotational synchronization between the central block 3 and the outer bushing 5b is realized.

[0037] See Figure 3 and Figure 7 As shown, the corner block 2 includes a corner block seat 2a and a corner block shell 2b covering the corner block seat 2a. The corner block seat 2a is provided with a corner block 2 bushing through which the first connecting part 5a3 passes. The inner hole of the corner block 2 bushing forms the first irregular through hole 2a1 that cooperates with the first circumferential limiting structure. More specifically, the first circumferential limiting structure is a limiting plane 5a31 extending axially on the first connecting part 5a3, and the first irregular through hole 2a1 has a mating plane 2a11 that cooperates with the limiting plane 5a31. It should be noted that in this specific embodiment, three sets of limiting planes 5a31 and mating planes 2a11 are used, that is, three limiting planes 5a31 are arranged circumferentially on the first connecting part 5a3. Correspondingly, three mating planes 2a11 are arranged circumferentially inside the first irregular through hole 2a1. This makes the circumferential locking between the corner block 2 and the inner shaft core 5a more stable.

[0038] See Figure 7 and Figure 8 As shown, the central block 3 has a central block 3 bushing through which the second connecting part 5b3 passes. The second circumferential limiting structure is a protrusion 5b31 extending radially along the second connecting part 5b3. The inner wall of the central block 3 bushing has a through groove 3a1 that mates with the protrusion 5b31. It should be noted that in this specific embodiment, three sets of protrusions 5b31 and through grooves 3a1 are used, that is, three protrusions 5b31 are arranged circumferentially on the second connecting part 5b3. Correspondingly, three through grooves 3a1 are arranged circumferentially in the second irregular perforation 3a. This makes the circumferential locking between the central block 3 and the outer bushing 5b more stable.

[0039] like Figure 3 As shown, the inner shaft core 5a is provided with a shaft positioning post 5a4 extending to the bottom of the lower pressure plate 5a1, and the ball core 1b is provided with a shaft positioning hole that mates with the shaft positioning post 5a4. The shaft positioning post 5a4 can rotate within the shaft positioning hole. The mating of the shaft positioning post 5a4 and the shaft positioning hole ensures the accuracy of the bottom position of the rotating shaft 5.

[0040] like Figure 3As shown, the inner side of the spherical shell 1a is provided with a limiting groove 1a11 that cooperates with the upper pressure plate 5b1, and the upper pressure plate 5b1 can rotate in the limiting groove 1a11. The limiting groove 1a11 cooperates with the upper pressure plate 5b1 to limit the upper pressure plate 5b1, preventing the rotating shaft 5 from shaking. At the same time, the limiting groove 1a11 applies a clamping force to the upper pressure plate 5b1, ensuring stable contact between the upper brush plate 5b2 and the lower brush plate 5a2 and the double-sided brush plate circuit board 5c.

[0041] like Figure 8 As shown, the double-sided brush circuit board 5c is provided with positioning holes, and the spherical core 1b is provided with circuit board positioning posts 1b1 that cooperate with the positioning holes. More specifically, there are at least two sets of positioning holes and positioning posts cooperating to ensure the circumferential positioning of the double-sided brush circuit board 5c.

[0042] like Figure 7 As shown, the spherical shell 1a includes an upper shell 1a1 and a lower shell 1a2, which are connected by a snap-fit ​​connection. The upper shell 1a1 is also connected to the spherical core 1b by a snap-fit ​​connection.

[0043] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
