The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation of the present utility model.

[0019] First Embodiment:

[0020] Please refer to Figures 1 to 4 , in which Figure 1 is a schematic connection structure diagram of the waterproof buckle structure of the present utility model and the local body sheet metal. Figure 2It is a schematic structural diagram of the waterproof buckle structure of the present utility model, Figure 3 It is a connection schematic diagram of the waterproof buckle structure of the present utility model, Figure 4 It is a cross-sectional view of the waterproof buckle structure of the present utility model.

[0021] A waterproof buckle structure of the present utility model: It includes a disc 1, a pressing seat 2, a plastic buckle 3, a soft rubber ring 4 and a sponge washer 5. The plastic buckle 3 includes a main rod 31 and an inclined rod 32. The plastic buckle 3 has a connection hole 33. The soft rubber ring 4 has a sleeve hole 41. The pressing seat 2 includes a connection column 21 and a clamping plate 22. Through the foregoing solution, the problem of water seepage in the sheet metal hole that occurs with a small probability in the existing waterproof buckle, as well as the problem of resonance abnormal noise in exterior trim parts such as the wheel arch and the lower exterior trim panel of the car door, are solved; it can be understood that the foregoing solution can form a double waterproof property through the sponge washer 5 and the soft rubber ring 4 to solve the problem of water seepage in the sheet metal hole that occurs with a small probability in the waterproof buckle, and greatly improve the NVH damping performance.

[0022] In this embodiment, the seat 2 is fixedly connected to the disc 1 and is located on one side of the disc 1. The plastic buckle 3 is fixedly connected to the disc 1 and is located on the other side of the disc 1. The soft rubber ring 4 is fixedly connected to the disc 1 and is sleeved on the disc 1. The sponge washer 5 is fixedly connected to the soft rubber ring 4 and is located on the inner side wall of the soft rubber ring 4. The sleeve hole 41 penetrates through the soft rubber ring 4 and cooperates with the disc 1. The plastic buckle 3 cooperates with the doghouse structure of the plastic part. The plastic buckle 3 is inserted into the doghouse of the plastic part. The installation method mainly depends on visual inspection + tactile and sound feedback during the installation process to determine whether the plastic buckle 3 has been accurately installed in place. Then, the primary and secondary positioning posts of the plastic part are pre-installed and aligned with the positions of the sheet metal holes of the vehicle body. Then, press the seat 2 with hand and vertically tap the plastic buckle 3 in the normal direction to complete the installation, thereby realizing the connection and fixation of the plastic part and the sheet metal part. The plastic buckle 3 is installed at the middle position of the disc 1. The shape of the outer ring of the disc 1 matches the shape of the sleeve hole 41 of the soft rubber ring 4, so that the soft rubber ring 4 is sleeved and fixedly installed on the disc 1 through the sleeve hole 41. Through the cooperation of the soft rubber ring 4 and the sheet metal hole of the vehicle body sheet metal, waterproofing is achieved through sealing. The sponge washer 5 is fixedly arranged in the inner wall of the soft rubber ring 4. The sponge washer 5 is a 1mm thick EPDM closed-cell foam washer. The sponge washer 5 is annular, and its inner diameter matches the plastic buckle 3. Through the simultaneous interference fit of the soft rubber ring 4 and the sponge washer 5 with the sheet metal, a double waterproof effect is achieved. The waterproof performance of the buckle can reach 300mm water column for 10 minutes, and it can greatly improve the NVH shock absorption performance. Moreover, when the soft rubber ring 4 is deformed or the clamping depth is inconsistent (the buckle is slightly warped), resulting in non-fitting between the soft rubber ring 4 and the sheet metal, the waterproof effect can also be achieved through the sponge washer 5. Therefore, when the plastic buckle 3 is aligned with the correct position and the plastic buckle 3 is installed in place by pressing or tapping the seat 2 with hand, a specific sound will be emitted and there will be a certain sense of resistance, indicating that the buckle has been firmly fixed. Through the interference fit of the soft rubber ring 4 and the sponge washer 5 inside it with the sheet metal, a double waterproof effect is achieved, and the sponge washer 5 and the soft rubber ring greatly improve the NVH shock absorption performance, thereby solving the problem of water seepage through the sheet metal holes that occurs with a low probability in the waterproof buckle structure, and the problem of resonance abnormal noise of exterior trim parts such as wheel arches and outer door lower trim panels.

[0023] Among them, the main rod 31 is fixedly connected to the disc 1 and is located at the middle position on one side of the disc 1; the inclined rods 32 are fixedly connected to the main rod 31 and are located on the opposite sides of the main rod 31. The connecting hole 33 penetrates through the main rod 31 and the inclined rods 32 and is located at one end of the main rod 31 away from the disc 1. The upper ends on the left and right sides of the main rod 31 are relatively inclined and symmetrically provided with the inclined rods 32. The main rod 31 and the inclined rods 32 form an arrow shape, and the connecting hole 33 is provided through the end where the main rod 31 and the two inclined rods 32 converge. Through the connecting hole 33, it is the connection point between the plastic buckle 3 and the connecting component, and the plastic buckle 3 can be fixed at the required position.

[0024] Then, the connecting column 21 is fixedly connected to the disc 1 and is located in the middle on the side of the disc 1 close to the clamping plate 22; the clamping plate 22 is fixedly connected to the connecting column 21 and is located at one end of the connecting column 21 away from the disc 1. The connecting column 21 is coaxially connected to the disc 1. One end of the connecting column 21 away from the disc 1 is fixedly connected to the clamping plate 22, and the clamping plate 22 is coaxially connected to the connecting column 21. Through the connecting column 21 and the clamping plate 22, it is convenient to apply force to press the plastic buckle 3 into connection and is also convenient for subsequent removal.

[0025] When using a waterproof buckle structure of the present utility model, when the plastic buckle 3 is aligned with the correct position and the plastic buckle 3 is installed in place by pressing or patting the pressing seat 2 by hand, a specific sound will be emitted and there will be a certain sense of resistance, indicating that the buckle has been firmly fixed. Through the soft rubber ring 4 and the sponge washer 5 inside it, an interference fit with the sheet metal achieves a double waterproof effect, and the sponge washer 5 and the soft rubber fully greatly improve the NVH damping performance, thereby solving the problem of water seepage in the sheet metal hole that occurs with a low probability in the waterproof buckle structure and the problem of resonance abnormal noise of exterior trim parts such as the wheel arch and the lower exterior trim panel of the door.
