Technical Field

[0001] The utility model relates to the technical field of toys, in particular to a joint structure and a doll thereof. Background Art

[0002] Currently, there are many design structures for joints in toys, but most of them mechanically imitate the appearance or movements of animals or machines. In particular, the joint movements of some animated characters are more complex, and the joints often have more than two rotational structures, making the joint movements more complicated. How to reflect these complex movements in toys has become a technical problem that needs to be solved urgently. Utility Model Content

[0003] In view of the defects in the prior art, the purpose of the present invention is to provide a joint structure and a doll thereof.

[0004] According to the present invention, a joint structure is provided, which is capable of switching between an extended state and a flexed state, and includes a joint body, and a first building block and a second building block, each of which is capable of rotating relative to the joint body. The joint body has a first mating portion, and the second building block has a second mating portion that matches the first mating portion, and the second mating portion is capable of moving between a first position and a second position in the first mating portion.

[0005] When the joint structure is in an extended state, the second matching portion is in a first position in the first matching portion. During the switching process from the extended state to the bent state, the first building block drives the joint body to rotate relative to the second building block until the second matching portion is in the second position in the first matching portion. The rotation of the joint body relative to the second building block is limited. At this time, the first building block rotates relative to the joint body until the joint structure reaches the bent state.

[0006] Preferably, the movement between the first matching portion and the second matching portion is sliding.

[0007] Preferably, the first matching portion is a limiting groove, and the second matching portion is a limiting column.

[0008] Preferably, the limiting groove is an arc-shaped groove.

[0009] Preferably, the joint body has a first rotation structure, and the second building block is configured with a third rotation structure that matches the first rotation structure to achieve rotational cooperation with the joint body.

[0010] Preferably, the joint body has a second rotation structure, and the first building block is configured with a fourth rotation structure that matches the second rotation structure to achieve rotational cooperation with the joint body.

[0011] Preferably, the rotational friction force of the first building block relative to the joint body is greater than the rotational friction force of the second building block relative to the joint body.

[0012] Preferably, the rotation is a relative rotation generated by the shaft-hole matching structure.

[0013] Preferably, when the first building block rotates relative to the joint body to reach the bent state, the rotation tendency of the first building block is interfered by the joint body.

[0014] Preferably, the joint body further comprises a function plate, wherein the function plate is spliced ​​on the joint body. Preferably, the function plate rotates synchronously with the first building block during the movement of the second matching portion from the first position to the second position in the first matching portion.

[0015] Preferably, when the joint structure is in the extended state, the functional plate and the second building block are in a closed state, and the first matching portion is not visible from the outside; when the joint structure is in the bent state, the functional plate and the second building block are in a separated state, and the first matching portion can be seen from the outside.

[0016] Preferably, the second building block is provided with a second building block assembly structure.

[0017] The utility model provides a doll comprising the joint structure.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The utility model designs the joint structure into a structure in which three building blocks, namely a joint body, a first building block and a second building block, cooperate to realize complex movement of the joint through rotation and limit integration. When the first building block rotates, the joint body can be driven to move to achieve a special display effect. The structure is cleverly coordinated and highly integrated, ensuring stability while achieving high simulation requirements, greatly enhancing the fun of the toy. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art further understand the present invention, but are not intended to limit the present invention in any way. It should be noted that a person skilled in the art may make various variations and improvements without departing from the scope of the present invention. Such variations and improvements are all within the scope of protection of the present invention.

[0038] Example 1:

[0039] The utility model provides a joint structure, such as Figures 1 to 4 As shown, it can switch between an extended state and a bent state, and includes a joint body 1, a first building block 2, and a second building block 3. The first building block 2 and the second building block 3 can respectively rotate relative to the joint body 1. The joint body 1 has a first matching portion, and the second building block 3 has a second matching portion that matches the first matching portion. The second matching portion can move between a first position and a second position in the first matching portion. The first matching portion is preferably a limiting groove 11, and the second matching portion is preferably a limiting column 32. The limiting groove 11 can limit the movement of the limiting column 32 in the limiting groove 11. The limiting groove 11 is preferably an arc groove, wherein the movement between the first matching portion and the second matching portion is preferably sliding, so that the stability is better.

[0040] Furthermore, when the joint structure is in the extended state, Figure 2 As shown, the second matching portion is in the first position in the first matching portion, which becomes a limit point of the second matching portion in the first matching portion. During the switching process from the extended state to the bent state, the first building block 2 drives the joint body 1 to rotate relative to the second building block 3. Figure 3 The figure shows that the second matching portion is rotated counterclockwise until it is in the second position in the first matching portion, which becomes another limit point of the second matching portion in the first matching portion, as shown in FIG. Figure 3 As shown, the rotation of the joint body 1 relative to the second building block 3 is limited, that is, the limiting post 32 slides from one end of the limiting groove 11 to the other end, and the joint body 1 can no longer rotate relative to the second building block 3. When the first building block 2 continues to rotate counterclockwise, it is converted into the rotation of the first building block 2 relative to the joint body 1 until the joint structure reaches a bent state. At this time, the first building block 2 and the second building block 3 are in contact and resist each other, and the rotation trend is blocked by the second building block 3. That is, when the first building block 2 rotates relative to the second building block 3 to reach the bent state, the rotation trend of the first building block 2 is interfered with by the second building block 3, as shown in FIG. Figure 4 The rotation of the first building block 2 in the present invention can drive the joint body 1 to rotate by a certain angle. When observed from the outside, relative motion occurs between the joint body 1 and the second building block 3, which can simulate dynamic scenes of various characters and increase the visual simulation of the toy.

[0041] It should be noted that the joint structure of the present invention can be used for joints in multiple parts, such as the leg joints. Figure 2 As shown, the extended state is not a straight state; the leg is also bent overall. However, in the extended state, the first building block 2 is not allowed to rotate clockwise. The joint structure of the present invention is applicable to various scenes of animated characters and can also be used to shape animal toys such as ostriches and kangaroos, thus having a wide range of applications. With further structural adjustments, the extended state can also be designed to be a straight state, which can be applied to dolls to achieve simulation of joint movement.

[0042] Specifically, the joint body 1 has a first rotating structure 12, and the second building block 3 is configured with a third rotating structure 31. The first rotating structure 12 and the third rotating structure 31 can be assembled together to rotate and cooperate, becoming the first fulcrum for the movement of the joint structure, thereby realizing the rotational cooperation of the second building block 3 and the joint body 1. The joint body 1 has a second rotating structure 13, and the first building block 2 is configured with a fourth rotating structure 21. The second rotating structure 13 matches the fourth rotating structure 21 and can be assembled together to connect the joint body 1 and the first building block 2, becoming the second fulcrum for the movement of the joint structure, thereby realizing the rotational cooperation of the first building block 2 and the joint body 1. It should be noted that the rotating structures that rotate and cooperate with each other preferably adopt an axial hole matching structure, which can realize the function of mutual splicing and connection, and at the same time, can realize the function of relative rotation, complete the corresponding action, have a simple structure, and are easy to operate.

[0043] In order to achieve the switching between the extended state and the bent state, the rotational friction of the first building block (2) relative to the joint body 1 is greater than the rotational friction of the second building block 3 relative to the joint body (1), so that before the first building block 2 and the joint body 1 rotate, the joint body 1 and the second building block 3 rotate first. It should be noted that if the relative movement between the limiting groove 11 and the limiting column 32 is sliding, the rotational friction of the first building block 2 relative to the joint body 1 is greater than the sum of the rotational friction of the second building block 3 relative to the joint body 1 and the sliding friction between the limiting groove 11 and the limiting column 32, so that before the first building block 2 and the joint body 1 rotate, the joint body 1 and the second building block 3 rotate first, thereby improving the simulation of the toy and increasing the fun.

[0044] In order to increase the external aesthetics, the present invention is further provided with a functional plate 4, which is spliced ​​on the joint body 1 and can achieve the effect of covering up the ugliness, such as Figure 2 As shown, in the extended state, the functional plate 4 can partially obscure the gap between the first building block 2 and the second building block 3. Therefore, when observed from the outside, the internal groove and other structures are obscured by the functional plate 4, creating a simple and beautiful appearance. The functional plate 4 is fixedly connected to the joint body 1 and moves synchronously. As the second mating portion moves from the first position to the second position in the first mating portion, the functional plate 4 rotates synchronously with the first building block 2. When the joint structure is in the extended state, the functional plate 4 and the second building block 3 are in a closed state, and the first mating portion is not visible from the outside. When the joint structure is in the bent state, the functional plate 4 and the second building block 3 are separated, and the first mating portion is visible from the outside.

[0045] The present invention also provides a doll, including a joint structure, wherein a second building block 3 is provided with a second building block assembly structure 33, and the second building block assembly structure 33 is preferably a male head or a female head for splicing and expanding, so that the joint structure can be spliced ​​and expanded to form various doll shapes, thereby increasing the fun of the toy.

[0046] Example 2:

[0047] This embodiment differs from Example 1 in that the rotational friction of the first building block 2 relative to the joint body 1 is less than the rotational friction of the second building block 3 relative to the joint body 1. This allows the first building block 2 and the joint body 1 to rotate first, and once fully rotated, the joint body 1 and the second building block 3 rotate. In actual applications, regardless of the magnitude of the friction between the various rotational mating structures, the joint structure can switch between the extended and flexed states. Only the order of relative rotation during rotation varies, which can be flexibly selected based on the specific usage scenario to meet the requirements of fun, simulation, and aesthetics.
