[0073] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention.

[0074] Example 1:
[0075] This utility model provides a crotch-shaped modular structure, such as Figure 1 , Figure 3 , Figure 10 As shown, the device includes a first component 1 and a second component 2. The first component 1 has a shaft 11 and an arc-shaped hole 12. The arc-shaped hole 12 includes an inner arc-shaped segment 121 and an outer arc-shaped segment 122. The arc lengths of the outer arc-shaped segment 122 and the inner arc-shaped segment 121 can be different or the same. The inner arc-shaped segment 121 and the outer arc-shaped segment 122 are connected. The inner arc-shaped segment 121 and the outer arc-shaped segment 122 can be arranged in parallel or in a non-parallel arrangement, such as... Figure 5 As shown, the two ends of the inner arc segment 121 protrude slightly inward, which allows the second accessory 2 to have a larger range of rotation and greater flexibility.
[0076] like Figure 1 , Figure 3 , Figure 8As shown, the second accessory 2 is disposed inside the first accessory 1, and has a connecting part 21 and a switchable hole 22. The end of the connecting part 21 extends into the arc-shaped hole 12 or the end of the connecting part 21 passes through the arc-shaped hole 12 and extends to the outside of the first accessory 1. The arc-shaped hole 12 limits and guides the movement of the connecting part 21. The switchable hole 22 includes an inner hole 221 and an outer hole 222. The inner hole 221 communicates with the outer hole 222. The shaft 11 passes through the switchable hole 22, and the shaft 11 is allowed to switch between the inner hole 221 and the outer hole 222 under the drive of external force, and is not allowed to switch between the inner hole 221 and the outer hole 222 in the natural state.
[0077] Specifically, when the shaft 11 is located in the inner hole 221, as Figure 8 , Figure 9 As shown, the connecting part 21 is located in the outer arc-shaped segment 122 and can rotate around the shaft 11 within the outer arc-shaped segment 122 under the drive of an external force; when the shaft 11 is located in the outer hole 222, as... Figure 3 , Figure 4 As shown, the connecting part 21 is located in the inner arc-shaped segment 121 and can rotate around the shaft 11 within the inner arc-shaped segment 121 under the drive of external force. The end of the connecting part 21 is connected to the intermediate connecting member 3, through which the thigh block can be connected. By switching the shaft 11 in the inner hole 221 and the outer hole 222, this invention allows the connecting part 21 to rotate in either the inner arc-shaped segment 121 or the outer arc-shaped segment 122, enabling the thigh to switch between different rotation trajectories, expanding the trajectory of thigh rotation. At the same time, when switching the thigh rotation trajectory, it has the effect of the leg appearing to lengthen, enhancing the fun of the toy.
[0078] like Figure 2 , Figure 3 , Figure 8 As shown, the second accessory 2 includes a third part 23 and a fourth part 24, which are detachably connected. The third part 23 has a first body 232 and a first connector 231 disposed on the first body 232. The fourth part 24 has a second body 242 and a second connector 241 disposed on the second body 242. The inner surfaces of the first body 232 and the second body 242 are arranged opposite to each other and are detachably connected. The first connector 231 is disposed on the outer surface of the first body 232, and the second connector 241 is disposed on the outer surface of the second body 242, such that the first connector 231 and the second connector 241 are arranged opposite to each other. The first connector 231 and the second connector 241 together form a connecting portion 21.
[0079] It should be noted that the first body 232 and the second body 242 are connected by a snap-fit or by a male-female connector structure. The first body 232 has a first through hole and the second body 242 has a second through hole. The first through hole and the second through hole have the same shape and are arranged opposite each other. When the first body 232 and the second body 242 are connected, the first through hole and the second through hole together form a switchable hole 22. The switchable hole 22 has a structure that is slightly narrower in the middle and round at both ends. The narrower part allows the shaft 11 to pass through under the drive of external force, but in the natural state, the narrower part does not allow the shaft 11 to pass through.
[0080] like Figure 2 As shown, both the first body 232 and the second body 242 are preferably plate-shaped structures. The ends of the first connector 231 and the second connector 241 extend in opposite directions on the first body 232 and the second body 242, respectively. Both the first connector 231 and the second connector 241 are preferably columnar structures. In practical applications, the end of the first connector 231 is a male or female head, and the end of the second connector 241 is a male or female head. The ends of the first connector 231 and the second connector 241 are connected to the intermediate connector 3. The end of the intermediate connector 3 also has a splicable structure, which can connect to the thigh block to achieve connection with the leg.
[0081] like Figure 1 , Figure 2 As shown, the first component 1 includes a first part 13 and a second part 14, which are detachably connected. A receiving space is formed between the first part 13 and the second part 14. Both the first body 232 and the second body 242 are arranged in the receiving space, allowing them to slide within the space, thereby enabling the shaft 11 to switch between the inner hole 221 and the outer hole 222. In practical applications, the shaft 11 can be configured on either the first part 13 or the second part 14, and can be flexibly designed according to the actual application scenario.
[0082] like Figure 2 As shown, the first part 13 has a first track hole 131, and the second part 14 has a second track hole 141. The first track hole 131 and the second track hole 141 have the same shape and are arranged opposite each other. The first track hole 131 and the second track hole 141 together form an arc-shaped hole 12. The end of the first connector 231 passes through the first track hole 131, and the end of the second connector 241 passes through the second track hole 141. The end of the first connector 231 is connected to one of the intermediate connectors 3 for connecting the right leg block, and the end of the second connector 241 is connected to the other intermediate connector 3 for connecting the left leg block.
[0083] like Figure 1As shown, the upper end of the first component 1 is provided with a splicing structure 15. The splicing structure 15 is disposed on the first part 13 or the second part 14. The splicing structure 15 can be a male or female head. In this embodiment, the splicing structure 15 is a ball head structure, which is beneficial to the realization of hip bending movements.
[0084] This utility model also provides a toy, including a hip block structure. By setting a hip block structure on the toy, the trajectory of thigh rotation is expanded, which meets the modeling needs of doll toys in different scenarios and increases the fun of the toy.
[0085] Example 2:
[0086] The difference between this embodiment and embodiment 1 is that the first body 232 and the second body 242 adopt an integrally formed structure.
[0087] In this embodiment, the splicing structure 15 is a ball-and-socket structure.
[0088] The working principle of this utility model is as follows:
[0089] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the shaft 11 is located in the outer hole 222, and the connecting part 21 is located in the inner arc-shaped section 121. Driven by an external force, the connecting part 21 can rotate around the axis of the shaft 11 within the inner arc-shaped section 121. The end of the connecting part 21 is connected to the intermediate connecting piece 3, which is connected to the thigh block, enabling the thigh to rotate. Figure 7 As shown.
[0090] like Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, the shaft 11 is located in the inner hole 221, and the connecting part 21 is located in the outer arc-shaped section 122. Driven by an external force, the connecting part 21 can rotate around the axis of the shaft 11 within the outer arc-shaped section 122, thus enabling the rotation of the thigh. Figure 12 As shown.
[0091] This invention allows the shaft 11 to be switched between the inner hole 221 and the outer hole 222 by hand force, thereby enabling the connecting part 21 to be switched to the inner arc segment 121 or to rotate within the outer arc segment 122. This expands the trajectory of thigh rotation, meets the needs of posture changes in different scenarios, and increases the fun of the toy.
