[0057] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0058] The utility model provides a joint building block structure, such as Figure 1 As shown, it can switch between a flying kick state, a cross-legged state and an upright state, and includes a middle building block assembly, an upper thigh building block 3, a lower thigh building block 4, a knee building block 5 and a calf building block 6. The two sides of the middle building block assembly are respectively rotatably matched with the upper ends of the two upper thigh building blocks 3. Specifically, the middle building block assembly includes a building block body 1 and a middle building block 2. Specifically, the active matching relationship between the building block body 1, the middle building block 2 and the upper thigh building block 3 belongs to the prior art, and the technical solution disclosed in the patent document CN116271870A can be referred to, which will not be repeated here.

[0059] Furthermore, the lower end of the upper thigh building block 3 and the upper end of the lower thigh building block 4 form a revolving pair, the lower end of the upper thigh building block 3 is provided with a first thigh assembling structure 31, and the upper end of the lower thigh building block 4 is provided with a second thigh assembling structure 41, the first thigh assembling structure 31 matches the second thigh assembling structure 41 so that the two can be spliced ​​together to form a revolving pair, the first thigh assembling structure 31 and the second thigh assembling structure 41 can adopt a male head matching female head structure, the first thigh assembling structure 31 is a male head, the second thigh assembling structure 41 is a female head, or the first thigh assembling structure 31 is a female head, and the second thigh assembling structure 41 is a male head, which can be flexibly set in actual application. In order to increase the stability of the toy and the feel of the splicing, the male head adopts a splicing column structure, and the female head is designed to match the splicing hole of the splicing column, wherein a protrusion 411 is provided on the splicing column, and the protrusion 411 can be designed as a point shape or a line shape. On the one hand, the design of the protrusion 411 can increase the damping of the splicing column and the splicing hole in the axial direction, so that the splicing column and the splicing hole after splicing are not easy to disengage. On the other hand, the design of the protrusion 411 can also increase the feel during the splicing process. At the same time, in order to bring a better experience to the players, a groove matching the protrusion 411 is provided on the inner surface of the splicing hole, so that the splicing can be positioned when the splicing column and the splicing hole are spliced. When the splicing is in place, a slight "click" sound will be emitted, which increases the high-end feel of the toy. In practical applications, the male head and the female head can also adopt a structure in which a ball head and a ball socket are matched, which can also achieve the effect of the utility model. The utility model designs the thigh to be split and rotatably matched, which greatly increases the simulation and restoration degree of the joint building block structure.

[0060] like Figure 1 As shown, the two ends of the knee building block 5 are respectively rotatably matched with the lower end of the lower thigh building block 4 and the upper end of the calf building block 6. Specifically, the knee building block 5 includes a knee piece 51 and a knee body 52. ​​The knee piece 51 and the knee body 52 are an integral structure or a split structure. In a possible embodiment, the knee piece 51 and the knee body 52 are a split structure, such as Figure 2 As shown, a male head is provided on the knee piece 51, and a female head is provided on the knee body 52. ​​The knee piece 51 can be spliced ​​to the female head of the knee body 52 through its own male head. The female head is a splicing hole 5211. The knee building block 5 adopts a building block splicing method. The utility model designs the knee as a double-joint structure, which has a higher degree of simulation and restoration than the prior art, and increases the fun of the toy.

[0061] like Figure 1As shown, the lower end of the lower thigh building block 4 has a third thigh building structure 42, and the upper end of the knee body 52 has a fourth thigh building structure 521, and the third thigh building structure 42 matches the fourth thigh building structure 521 so that the two can rotate together. Similarly, the upper end of the calf building block 6 has a sixth thigh building structure 61, and the lower end of the knee body 52 has a fifth thigh building structure 522, and the fifth thigh building structure 522 matches the sixth thigh building structure 61 so that the two can rotate together. In actual applications, the third thigh building structure 42 and the fourth thigh building structure 521, the fifth thigh building structure 522 and the sixth thigh building structure 61 all adopt a structure in which the splicing groove 001 matches the building block piece 002. In a possible embodiment, as Figure 3 As shown, the building block 002 has a rotating hole 0021, and the two sides of the splicing groove 001 have convex shafts 0011 arranged with gaps. When the building block 002 is assembled into the splicing groove 001, the end of the convex shaft 0011 extends into the rotating hole 0021 and rotates with the rotating hole 0021. It should be noted that when the building block structure is spliced, the maximum thickness of the building block 002 passing through the gap is greater than the gap, so that when the building block 002 passes through the gap, the two convex shafts 0011 are stretched open, thereby making the gap larger and the two convex shafts 0011 return to their original positions after the splicing is in place, and the end of the convex shaft 0011 extends into the rotating hole 0021, which realizes both the limiting function and the rotational cooperation function.

[0062] The joint building block structure in the utility model can be adjusted to a cross-legged state, and a support point 32 is arranged on the circumference of the top of the upper thigh building block 3, such as Figure 6 As shown, the joint building block structure in the cross-legged state avoids the possibility of tipping over due to the setting of the support points 31, so that the entire structure has better stability than other structures in the prior art.

[0063] The present invention also provides a toy including a joint building block structure, such as a humanoid toy, which can switch between a flying kicking state, a cross-legged state and an upright state, greatly increasing the flexibility or fun of the toy. In a specific embodiment, Figure 1 As shown, the toy also includes a chest building block 8 and a shoulder building block 10. The upper end of the chest building block 8 is spliced ​​and connected to the lower end of the shoulder building block 10 through a connecting building block 9. The upper end of the shoulder building block 10 is spliced ​​with a neck building block 7. The lower end of the chest building block 8 is spliced ​​and connected to the upper end of the building block body 1. The left and right ends of the shoulder building block 10 are then spliced ​​with two arms to realize the splicing of the toy.

[0064] The principles of each state in the utility model are as follows:

[0065] Flying kick state: the joint building block structure is in an upright state, the right leg is rotated in a straight state at the connection between the middle building block assembly and the upper thigh building block 3 to achieve lifting to the right, the left leg is also rotated at the connection between the middle building block assembly and the upper thigh building block 3 to achieve lifting to the right, and the lower thigh building block 4 is rotated 90° relative to the upper thigh building block 3 at the connection between the upper thigh building block 3 and the lower thigh building block 4, so that the calf building block 6 can be bent and lifted to the right relative to the lower thigh building block 4, thereby completing the flying kick to the right. Figure 4 The left leg is straightened and rotated at the connection between the middle building block assembly and the upper thigh building block 3 to lift it to the left, and the right leg is also rotated at the connection between the middle building block assembly and the upper thigh building block 3 to lift it to the left, and the lower thigh building block 4 is rotated 90° relative to the upper thigh building block 3 at the connection between the upper thigh building block 3 and the lower thigh building block 4, so that the calf building block 6 can be bent and lifted to the left relative to the lower thigh building block 4, thereby completing the flying kick to the left, as shown in FIG. Figure 5 shown.

[0066] Cross-legged state: The joint building block structure is in an upright state, first bend the left and right legs so that the rear end surface of the upper thigh building block 3 touches the ground, then rotate the lower thigh building block 4 of the right leg 90° outward relative to the upper thigh building block 3, and then bend the calf building block 6 relative to the lower thigh building block 4 so that the foot is close to the body; then rotate the lower thigh building block 4 of the left leg 90° outward relative to the upper thigh building block 3, and then bend the calf building block 6 relative to the lower thigh building block 4 so that the foot is close to the body, at this time the left leg presses the right leg to achieve the cross-legged action. It should be noted that the cross-legged state can also be a state where the right leg presses the left leg. For illustration purposes, the utility model only provides a structural diagram of the semi-extended leg state, such as Figure 7 shown.
