[0002] In modern automotive manufacturing, plastic clips are widely used as important connectors in the assembly of components such as car door panels. Traditional plastic clip designs primarily rely on claw structures to achieve fixing and limiting functions. While this design is simple and low-cost, it has revealed some problems in practical applications. Particularly during vehicle operation, the claws of traditional clips are prone to deformation due to continuous vibration and impact, leading to clip loosening. This not only affects the vehicle's sealing and safety but may also generate noise, reducing the driving experience. Therefore, we have made improvements and proposed a new type of plastic clip for car door panels. Utility Model Content

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] For an example, please refer to... Figures 1-4 A plastic snap fastener for automotive door panels includes a baffle 1. A plurality of claw bodies 101 are fixedly mounted on one side of the baffle 1. A limiting groove 102 is formed on the inner side wall of each claw body 101, and a protrusion is provided on the outer side surface of each claw body 101. A limiting part is provided between the limiting groove 102 and the baffle 1 to restrict the deformation of the claw body 101 during use. The limiting part can restrict the deformation of the claw body 101, ensuring relative stability even under external force, reducing the risk of the claw body 101 loosening due to deformation, thereby improving the connection strength and reliability of automotive door panels and other components. When the snap fastener needs to be removed, the limiting part can move and release the limiting on the claw body 101, thus achieving snap fastener separation. This ensures ease of installation and facilitates subsequent maintenance and replacement.

[0029] Furthermore, a receiving groove 103 is also provided on the inner side wall of the claw body 101. The receiving groove 103 is located between the limiting groove 102 and the baffle 1. When the limiting ball 104 moves into the receiving groove 103, the limiting of the claw body 101 can be released, so that when the end of the claw body 101 away from the baffle 1 deforms and bends inward during dismantling, it will not be limited by the limiting ball 104, thereby avoiding the limiting ball 104 from affecting the deformation of the claw body 101 during dismantling.

[0030] Furthermore, the limiting part includes a limiting ball 104, which is disposed between a plurality of claw bodies 101 and contacts the inner wall of the limiting groove 102. When the limiting ball 104 is located inside the limiting groove 102, it can limit the end of the claw body 101 away from the baffle 1.

[0031] Furthermore, a through hole is provided in the middle of the baffle 1, and a connecting rod 105 is inserted into the through hole. One end of the connecting rod 105 is connected to the limiting ball 104. The setting of the connecting rod 105 facilitates the movement of the limiting ball 104 to adjust the position of the limiting ball 104.

[0032] Furthermore, a limiting element is provided at the end of the connecting rod 105 away from the limiting ball 104. The limiting element is located on the side of the baffle 1 away from the claw body 101. The limiting element can cooperate with the connecting rod 105 to limit the stroke when the limiting ball 104 moves away from the baffle 1.

[0033] Furthermore, the limiting component includes a limiting rod 106, which is fixedly connected to the end of the connecting rod 105 away from the limiting ball 104, and the end of the limiting rod 106 near the baffle 1 contacts the baffle 1. The limiting rod 106 can limit the stroke of the limiting ball 104 when it moves away from the baffle 1.

[0034] Furthermore, the end of the limiting rod 106 away from the baffle 1 is fixedly connected to the limiting plate 107. The limiting plate 107 is designed to facilitate the use of an existing buckle removal wrench to pull the limiting rod 106 away from the baffle 1, and the limiting plate 107 can also be pulled by hand.

[0035] Furthermore, a spring 108 is sleeved on the outer surface of the connecting rod 105. The spring 108 is located between the baffle 1 and the limiting ball 104. The force of the spring 108 can limit the limiting ball 104, reducing the possibility of the limiting ball 104 moving towards the baffle 1 on its own. The spring 108 is in a compressed state, and its elastic force is directed from the baffle 1 to the limiting ball 104. Under normal conditions, it pushes the limiting ball 104 to the limiting groove 102 to achieve the limiting of the claw body 101.

[0036] Furthermore, a stop tube 109 is fixedly connected to the side of the limiting ball 104 near the baffle 1. The connecting rod 105 and the spring 108 are both inserted into the inner wall of the stop tube 109. A gap is left between the end of the stop tube 109 away from the spring 108 and the baffle 1. When the limiting ball 104 moves to the center of the receiving groove 103, the stop tube 109 contacts the baffle 1, so that the stop tube 109 can limit the stroke of the limiting ball 104 moving towards the baffle 1, so that the limiting ball 104 will not continue to move towards the baffle 1 after entering the area of ​​the receiving groove 103.

[0037] The usage process of the plastic clip for the car door panel provided by this utility model is as follows:

[0038] During installation, pull the limiting plate 107 away from the baffle 1. The limiting plate 107, through the limiting rod 106 and the connecting rod 105, pulls the limiting ball 104 into the receiving groove 103, i.e. Figure 4 As shown, the claw body 101 is installed by passing it through the corresponding mounting hole. When the claw body 101 passes through the mounting hole, the end of the claw body 101 away from the baffle 1 is tilted inward under the limitation of the mounting hole, so that the claw body 101 can pass through the mounting hole. After the claw body 101 passes through the mounting hole, the limiting plate 107 is released, and the force of the spring 108 pushes the limiting ball 104 away from the baffle 1, so that the limiting ball 104 enters the limiting groove 102 to achieve the desired position. The claw body 101 is limited and facilitates the reset of the claw body 101 to limit the car door panel; during disassembly, the limiting plate 107 is pulled away from the baffle 1, and the limiting plate 107 pulls the limiting ball 104 into the receiving groove 103 through the limiting rod 106 and the connecting rod 105. The limiting plate 107 is pulled further so that the end of the claw body 101 away from the baffle 1 is tilted and deformed inward under the limitation of the mounting hole, so that the claw body 101 passes through the mounting hole and thus completes the disassembly.
