Description

Technical Field

[0001] This utility model relates to the field of toy technology, specifically to a joint structure and a toy thereof. Background Technology

[0002] To meet players' needs for fun, existing doll products are not only becoming more and more realistic in appearance, but also constantly improving in terms of movement simulation to enhance the toys' sense of sophistication. Among these improvements, the design of the joints in doll toys is particularly crucial for creating a high degree of realism.

[0003] Taking the shoulder joint as an example, due to the limitations of simulation design and the requirements for appearance, existing shoulder joint designs still suffer from insufficient joint rotation force, poor stability, and unattractive appearance. Figure 9 As shown, because the outer block 3 is made of PVC thin plastic, and the other block in the joint is made of ABS or POM material, this structural design lacks sufficient rotational force (approximately 1 N·cm) and is prone to cracking. Furthermore, as... Figure 10 As shown, there is a large gap 101 between the two blocks, which seriously affects the quality and appearance. For example... Figure 11 As shown, because the outer layer block 3 cannot cover the key parts of the joints, there are flaws in the appearance, resulting in an unattractive shape; moreover, it requires manual assembly, which is costly. Given the shortcomings of existing technology, there is an urgent need to design a new structure to solve these defects. Utility Model Content

[0055] Gap 101 Detailed Implementation

[0056] 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. These all fall within the protection scope of the present invention.

[0057] Example 1:

[0058] This utility model provides a joint structure, including a joint structure such as... Figure 1 , Figure 2As shown, the assembly includes a first block 1, a second block 2, and an outer block 3. The first block 1, the second block 2, and the outer block 3 are all in different colors. The first block 1 is made of POM material. The first block 1 has a first end 11 and a second end 12. The first end 11 has a first shaft hole 111. The second end 12 is used to assemble other blocks. Specifically, the second end 12 can be designed as a male or female head, such as a structure that matches the shaft hole. The second end 12 can also be designed as a ball head or a ball socket structure to enable the first block 1 to be assembled with other blocks to create the desired shape.

[0059] like Figure 1 , Figure 2 As shown, the second building block 2 is made of ABS material. The second building block 2 has a first connecting portion 21 injection-molded onto the outside of the first end 11. The first connecting portion 21 is equipped with a tube that passes through the first shaft hole 111. The hole in the middle of the tube is the second shaft hole 211. During injection molding, the tube passing through the first shaft hole 111 makes the first building block 1 and the second building block 2 inseparable. Furthermore, the second building block 2 rotatably engages with the first building block 1, achieving the function of joint rotation. Figure 3 , Figure 4 , Figure 5 As shown, the first building block 1 made of POM material and the second building block 2 made of ABS material cooperate with each other, so that the pivoting force between the part of the first connecting part 21 with the second shaft hole 211 and the first shaft hole 111 is greater than 5 N·cm, which improves the pivoting force and the stability of the structure. Compared with the prior art, it eliminates the secondary assembly or pre-assembly process and also reduces the cost.

[0060] like Figure 1 , Figure 2 As shown, the outer block 3 is made of PVC and is injection molded outside the first connecting part 21. The outer block 3 has a positioning part 31 and an extension part 32. The positioning part 31 is provided with a shaft 311, which passes through the second shaft hole 211, so that the outer block 3 can be stably held on the second block 2 and is not allowed to move relative to the second block 2. The extension part 32 is fitted onto the second connecting part 22. Preferably, the end of the second connecting part 22 protrudes to the outside of the extension part 32, which facilitates the second connecting part 22 to be assembled with other blocks to form new toy shapes.

[0061] In practical applications, the second connecting part 22 can be designed as a male or female head, such as a structure where a hole and shaft are matched. The second connecting part 22 can also be designed as a ball head or a ball socket structure, and the specific choice can be made flexibly according to the actual application scenario.

[0062] like Figure 1 , Figure 2As shown, an annular protrusion 112 extends from one or both sides of the first end 11 along the axial direction, and the first connecting part 21 has an annular groove 23 that matches the annular protrusion 112. The annular groove 23 and the annular protrusion 112 cooperate to make the first block 1 and the second block 2 more stable when rotating.

[0063] In one possible embodiment, both sides of the first connecting part 21 are flat, the two ends of the shaft 311 that cooperate with the two sides of the first connecting part 21 are also flat, and the part where the positioning part 31 is connected to the outer surface of the first connecting part 21 is smoothly transitioned, making the outer surface of the joint more aesthetically pleasing.

[0064] This utility model also provides a toy, including a joint structure. The toy is preferably a human-shaped doll. The joint structure is assembled at the shoulder joint. The shoulder joint is made of mature ABS or POM joints with added PVC coating. While meeting the requirements of the PVC appearance and material of the product, the joint strength is increased. Through holes are added at the coated joint position, so that the PVC outer block with secondary coating can be tightened through the joint by the shaft. This can effectively prevent external deformation, and has the characteristics of structural stability, beautiful appearance, low cost, and improved feel and quality of the toy.

[0065] like Figure 6 , Figure 7 , Figure 8 As shown, the joint structure has three states: raised, extended, and lowered. Figure 6 The joint structures are in a downward-hanging state, for example, the shoulder joint is in a naturally hanging state. Figure 7 The mid-joint structure is in an extended position. Figure 8 The joint structure is in an upward-raised state. The above three states demonstrate the simulation scenarios of the joint in different postures.

[0066] Example 2:

[0067] This embodiment provides a joint structure. Unlike embodiment 1, the first block 1 is made of POM material, the second block 2 is made of PC material, and the outer block 3 is made of soft rubber material such as TPU. This embodiment can effectively prevent external deformation while ensuring the joint rotation force. It has the characteristics of structural stability and beautiful appearance, which improves the feel and quality of the toy.
