[0002] In the toy manufacturing industry, especially for toys requiring a high degree of flexibility and mobility, such as action figures, robotic toys, and animal models, the assembly and design of joints has always been a key and challenging area of ​​technological innovation. Currently, jointed toys on the market typically feature a pivoting connection between the joint and the main body. To ensure the joint remains stationary after rotation while maintaining flexibility, damping components are typically installed between the joint and the main body.

[0003] At present, the damping connection components on the market usually use rubber washers and screws. The joints are installed on the main body by screws, and washers are arranged between the screws and the joints to play a buffering role. As disclosed in the patent application with publication number CN206152324U (patent name: Toys with articulated motion accessories), the joint accessories are installed on the main body by screws and washers. Although this design can achieve joint movement, it has obvious defects. After a period of use, the toy joints are prone to loosening between the joints and the main body, resulting in the joints being unable to maintain after rotation and falling with inertia. This situation can only be solved by frequently adjusting the screws, but the flexibility of the joints will deteriorate after adjustment, and the screws may slip, causing the toy to be directly scrapped. This not only affects the play experience of the toy and reduces the durability of the product, but also joint dislocation may pose a potential threat to children's safety. Utility Model Content

[0006] Furthermore, the material of the damping connecting member includes polyformaldehyde.

[0011] Furthermore, the notch is formed by extending from the middle of the side wall of the connecting portion to the extending portions on both sides.

[0012] Furthermore, the damping friction surface is the inner wall of the extension portion or the outer wall of the extension portion.

[0034] Example 1:

[0035] This embodiment provides a damping connector 10, which can be applied to joint toys to assist the joint component 20 of the joint toy in rotating and provide damping force to help the joint component 20 maintain its position after rotation. Figure 1-4 The damping connector 10 includes a connecting portion 11 and a limiting portion 12, wherein the connecting portion 11 is cylindrical, and the connecting portion 11 passes through between the two bottom surfaces to form a cylindrical through hole 111 for nesting connection with the joint component 20. The nesting connection method includes an interference connection. The damping connector 10 is connected to the joint component 20 by an interference fit. After the joint component 20 rotates, the damping connector 10 provides damping friction to the joint component 20 to support it from falling. The connecting portion 11 is provided with a notch 13 on the side wall for adjusting the damping friction.

[0036] The connecting portion 11 is used for nested connection with the joint component 20, and the nested connection portion includes the cylindrical through hole 111 inside the connecting portion 11, and also includes the extension portion 14 of the side wall of the connecting portion 11. If the damping connector 10 is connected in an internal nested manner, the size and shape of the connecting end of the joint component 20 are adapted to the cylindrical through hole 111, and the joint component 20 can be inserted into the cylindrical through hole 111 through its connecting end, thereby being nested and connected with the damping connector 10. In terms of the connection method, the two adopt an interference connection, that is, after the nested connection, the two are abutted by the interference fit between the parts, thereby generating a supporting damping force. If the damping connector 10 is connected in an external nested manner, the connecting end of the joint component 20 is set to match the diameter of the extension portion 14 of the damping connector 10, and then a nested connection is performed through the extension portion 14. In this embodiment, the main connection method between the connecting portion 11 and the joint component 20 is an interference connection. The notch 13 of the connecting portion 11 provides the damping connector 10 with a certain interference fit to prevent complete jamming, thereby cooperating to adjust the damping friction between the damping connector 10 and the joint component 20. The limiting portion 12 is formed to protrude outward from the side wall of the connecting portion 11. Preferably, the limiting portion 12 is a rectangular protrusion that is used to cooperate with the limiting slot seat of the main component 30 to limit the axial rotation of the damping connector 10 and ensure relative fixation between the damping connector 10 and the main component 30.

[0037] For better explanation, an application scenario of a damping connector 10 is provided. In this application scenario, the damping connector 10 is arranged between the main body part 30 and the joint part 20, and is used to provide a damping support force for the rotational connection of the joint part 20, so as to complete the retention of the joint part 20 after the rotation relative to the main body part 30. The damping connector 10 adopts an interference connection method, and is sleeved on the connecting end of the joint part 20 through the cylindrical through hole 111 of the connecting part 11. The joint part 20 is rotatably mounted on the main body part 30 through the connecting end, and the damping connector 10 is fixed with the limiting slot seat inside the main body part 30 through the limiting part 12. At the same time, the hole wall of the cylindrical through hole 111 of the connecting part 11 of the damping connector 10 abuts against the outer wall of the connecting part 11 of the joint part 20 to form a damping friction force, so that after the rotation of the joint part 20, due to the existence of the damping friction force, the joint part 20 will not fall under the influence of gravity, so as to achieve the effect of retention after rotation.

[0038] The damping connector 10 can be positioned between the joint component 20 and the main body component 30. The connection portion 11 cooperates with the joint component 20 to provide damping friction for the joint component 20 after rotation, thereby maintaining the joint component 20 after rotation and preventing it from slipping. The damping connector 10 utilizes interference fit to provide damping friction, making it less susceptible to wear and loosening over time. Its durability enhances the rotation feel of the assembled toy, ensures the reliability of its joint movement, and avoids the risk of the joint falling during use, thereby improving the user experience of the product.

[0039] Some specific implementations of this embodiment are provided below.

[0040] In terms of materials, preferably, the material of the damping connector 10 in this embodiment includes POM (polyoxymethylene resin) material, which is a high-density, high-crystallinity thermoplastic engineering plastic with excellent friction resistance, and can ensure and increase the service life of the damping connector 10.

[0041] In terms of structural refinement, the notch 13 is preferably formed along the bottom surface of the connecting portion 11 on one side for nesting connection, extending toward the other bottom surface. This ensures that the joint component 20 is smoothly inserted into the cylindrical through hole 111 to achieve an interference fit. The stopper 12 is positioned near the bottom surface of the connecting portion 11 on the side for nesting connection. The height of the sidewall of the connecting portion 11 is greater than that of the stopper 12. A slot is provided in the middle of the stopper 12 along the bottom surface of one side of the connecting portion 11 toward the other side. This reduces the manufacturing cost of the damping connector 10 while achieving the limiting function.

[0042] In order to reduce the difficulty of nesting and docking between the connecting part 11 and the joint component 20, the connecting part 11 is provided with an air avoidance groove 113 at the opening on the bottom surface of the side used for nesting connection. The air avoidance groove 113 is formed by the hole wall of the circular through hole 111 being recessed from the inside to the outside, ensuring that the joint component 20 can be smoothly placed into the circular through hole 111, reducing the difficulty of assembly.

[0043] Example 2:

[0044] See also Figure 5-6This embodiment is similar to the embodiment 1. On the basis of the embodiment 1, the damping connector 10 of this embodiment is provided with extensions 14 extending to both sides of the bottom surface of the connecting portion 11. The damping connector 10 is respectively connected to the two joint components 20 through the extensions 14 on both sides of the connecting portion 11. Through the provision of the extensions 14, the damping connector 10 can provide damping friction for the rotational connection between the two joint components 20 and the main body component 30. For example, in one application scenario, the damping connector 10 is provided with extensions 14 on both sides. The extensions 14 are cylindrical. The damping connector 10 is limitedly provided on the main body component 30. The connecting sections of the two joint components 20 are respectively sleeved on the extensions 14. When the joint components 20 rotate on the main body component 30, they abut against and rub against the extensions 14 to form a damping friction force, so as to maintain the rotation and prevent the joint from slipping.

[0045] Specifically, as a preference, the joint component 20 is mated with the extension portion 14 through the connecting piece 21. Specifically, the connecting piece 21 is provided with an assembly hole that matches the diameter of the extension portion 14. The connecting piece 21 is fixedly connected to the joint component 20. The joint component 20 is nested and connected to the extension portion 14 through the connecting piece 21, and then interference-fits with the damping connecting piece 10. When the joint component 20 rotates, the joint component 20 abuts against the damping friction surface 112 through the assembly hole of the connecting piece 21, thereby maintaining its position after rotation.

[0046] As a preferred embodiment of the above scheme, when the damping connector 10 is provided with an extension portion 14, the notch 13 is formed by extending from the middle of the side wall of the connecting portion 11 to the extension portions 14 on both sides. This arrangement is also intended to meet the feasibility of the nested connection between the joint component 20 and the damping connector 10.

[0047] As one of the preferred embodiments, the damping friction surface 112 of the damping connector 10 includes the outer wall of the extension portion 14 and the inner wall of the extension portion 14. The damping friction surface 112 is used to cooperate with the joint component 20 to generate damping friction force by abutting friction to achieve a retention effect after the joint rotates.

[0048] Example 3:

[0049] See also Figure 1-6This embodiment provides a joint connection structure for a joint toy, which specifically includes a joint component 20, a main body component 30, and the damping connector 10 provided in Example 1. The damping connector 10 is mounted within the main body component 30 via a limiting portion 12, and the joint component 20 is rotatably mounted on the main body component 30. The connecting end of the joint component 20 is nested with the damping connector 10, and the connecting portion 11 is rotatably abutted against the main body component 30 via the damping connector 10 in the rotational direction. The abutment between the damping connector 10 and the joint component 20 generates a damping friction force, thereby maintaining the joint after rotation.

[0050] Of course, in some embodiments, the damping connector 10 is movably connected to the joint component 20, and the damping friction force is provided by the abutment friction with the joint component 20. In such a solution, the damping connector 10 is rotatably abutted against the main component 30 and is limited in position within the main component 30 by the limiting portion 12, thereby forming a relatively fixed locking state between the damping connector 10 and the main component 30.

[0051] More preferably, the nested connection between the joint component 20 and the damping connector 10 includes external nesting with the damping connector 10 outside and the joint component 20 inside, and internal nesting with the damping connector 10 inside and the joint component 20 outside.

[0052] The serial numbers of the embodiments of this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are only preferred embodiments of this application and do not limit the scope of the patent of this application.
