Description

Technical Field

[0001] This utility model relates to the technical field of automotive clips, specifically to a waterproof clip. Background Technology

[0002] Clips, as a common type of fastener, are often used to fix the trim panels and sheet metal of various car models. Typically, a clip includes an upper clip seat and a lower clip foot. By installing the clip seat on the clip seat located on the inner side of the trim panel, the clip foot passes through the sheet metal hole of the car body to complete the snap-fit, thereby realizing the fixed connection between the interior trim panel and the car body or the connection between trim parts.

[0003] Currently, the commonly used buckle material is usually soft plastic. While ensuring one-piece molding, the buckle foot part remains elastic so that it can bend inward during the process of passing through the fixing hole, and when fully inserted, the buckle foot can expand outward or rebound to achieve the function of supporting the connection.

[0004] The body panel holes are formed by stamping metal parts, and burrs are inevitably present on the edges of the punched holes. With the application of aluminum body panels, when holes are made by casting or machining, sharp edges will also appear on the edges of the holes. These problems will make it difficult to insert the plastic clips smoothly, resulting in greater installation force or even difficulty in installation. Therefore, waterproof clips with deburring structures are available on the market. The reason is that the clips made by existing molds have burr structures on the edges, which affects the installation effect. Our company has improved the processing technology, and the clip edges are burr-free, so there is no need for a deburring process. Therefore, a deburring structure is not required. In normal use, the clips combine the injection molded parts and the door sheet metal. During use, water may pass between the injection molded parts and the sheet metal, resulting in water accumulation.

[0005] Therefore, using a waterproof clip between the two can play a sealing role. Existing clips have burr rings on the outside, which can easily lead to the waterproof clip's deformation being restricted by the burr rings after the injection molded part and the door sheet metal are connected, thus preventing it from deforming completely. As a result, the connection between the injection molded part and the door sheet metal is not tight enough, and water and air can get in. Therefore, a waterproof clip needs to be designed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a waterproof buckle that can solve the problem that existing car buckles cannot fully deform, resulting in insufficient tightness between the injection molded part and the car door sheet metal, leading to water and air ingress.

[0007] To achieve the above objectives, this utility model relates to a waterproof buckle, comprising a base and a snap-fit ​​structure. The base includes an integrally formed lower disc, a central column, and an upper disc. The lower disc and the upper disc are connected by the central column. A snap-fit ​​structure is connected above the upper disc. The snap-fit ​​structure includes at least two sets of snap-fit ​​feet, and several sets of snap-fit ​​feet have the same structure. Each snap-fit ​​foot includes a raised cavity end face and a flat end structure integrally connected to the raised cavity end face. A vertical cavity structure is provided between two snap-fit ​​foot structures. The vertical cavity structure contains... The device has fixed column structures at the top and bottom of the side, and a reinforcing panel structure between the two fixed column structures. There is a gap between the two reinforcing panel structures, which serves as a buffer. The upper surface of the split-type locking foot has a raised end face. The raised end face is provided to protect the locking structure. When the waterproof buckle is connected to other components, the end of the locking structure will be subjected to great pressure. The raised end face can protect and disperse the force on the end of the locking structure, thereby protecting the locking structure and preventing breakage or damage.

[0008] A further improvement of this utility model is that a waterproof ring structure is provided on the edge of the upper disc. The waterproof ring structure can play a waterproof role and further prevent water from entering between the sheet metal and the injection molded part.

[0009] A further improvement of this utility model is that: a groove structure is provided on the outer side of the protruding cavity end face, and the longitudinal section of the groove structure is rice grain shaped. The groove structure can reinforce the protruding cavity end face and can play a rebound buffering role when the segmented clamping foot is subjected to external force.

[0010] A further improvement of this utility model is that: the lower end face of the groove structure is provided with a through hole structure, and the through hole structure can help the groove structure play a buffering role.

[0011] A further improvement of this utility model is that the protruding end face has a flat cylindrical structure, which serves to protect the upper end face of the flap structure.

[0012] A further improvement of this utility model is that the longitudinal cross-section of the bottom surface of the upper disc has a disc-shaped structure.

[0013] A further improvement of this utility model is that the lower end face of the base has an arc-shaped structure, which facilitates the connection between the injection molded part and the sheet metal.

[0014] The beneficial effects of this utility model are: This utility model design features a fixing post structure between the two segmented clip structures, and a reinforcing panel structure between the fixing post structures. A gap exists between the two reinforcing panel structures, providing reinforcement and buffering. The upper surface of each segmented clip has a raised end face to protect the clip structure. When the waterproof buckle is connected to other components, the end of the clip structure is subjected to significant pressure. The raised end face protects and disperses the force on the end of the clip structure, thus protecting it and preventing breakage or damage. The overall structural design ensures a tight connection between the injection molded part and the door sheet metal, preventing moisture and air from entering, increasing the buckle's lifespan, installation tightness, and overall stability.
