[0037] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0038] Embodiment 1

[0039] The present embodiment relates to a sealing gasket, which can improve the sealing effect and waterproof performance between the buckle and the plate body, thereby making the vehicle have better interior quality to enhance the customer experience.

[0040] In terms of overall structure, Figure 1 and Figure 2 As shown, the sealing gasket of this embodiment includes a disc-shaped gasket body 1, a snap-in hole 100 for the snap-in seat 2 to snap into is provided in the middle of the gasket body 1, and a plurality of annular sealing structures are provided on one side of the gasket body 1 for sealing.

[0041] Specifically, in this embodiment, as an exemplary structure, Figure 1 and Figure 2 As shown, the pad body 1 includes a clamping portion 10 located in the middle, and a sealing portion 11 connected to the periphery of the clamping portion 10 , a clamping hole 100 is opened in the center of the clamping portion 10 , and each sealing structure is arranged on the sealing portion 11 .

[0042] And, as the buckle seat 2 is inserted into the buckle hole 100, the buckle portion 10 is sealed and connected to the buckle seat 2. The advantage of such a setting is that the sealing effect between the buckle seat 2 and the sealing gasket can be ensured on the basis of reasonable arrangement, thereby facilitating the improvement of the overall sealing effect of the plate body.

[0043] See also Figure 2 , Figure 4and Figure 5 As shown, as a preferred implementation form, in this embodiment, in the radial direction of the pad body 1, the thickness of the sealing portion 11 is gradually reduced from the middle of the sealing portion 11 toward the outer edge of the sealing portion 11.

[0044] Here, the gradually thinning design of the sealing part 11 can make the middle part of the sealing part 11 thicker and harder, while the outer edge is thinner and harder, which is beneficial for the outer edge of the sealing part 11 to be more flexibly pressed against the plate body, thereby improving the sealing and waterproofing effects.

[0045] Moreover, as a preferred implementation form, in this embodiment, the multiple sealing structures include a lip 110 formed on the outer edge of the sealing portion 11, and a plurality of annular protrusions formed on the surface of the sealing portion 11. It can be understood that the provision of the lip 110 can increase the interference contact area with the plate body, enhance the effect of blocking water leakage, and cooperate with the plurality of annular protrusions to further enhance the effect of blocking water leakage.

[0046] For specific implementation, please refer to Figure 2 As shown, as a preferred implementation form, in this embodiment, the multiple annular protrusions include an inner sealing ring 111 and an outer sealing ring 112 arranged in concentric circles. Thus, two sealing and waterproof structures are formed, and the interference fit effect between the cushion body 1 and the mounting boss of the plate body is improved, so that the entire buckle can be firmly pressed against the plate body, achieving the purpose of effectively preventing water leakage.

[0047] At the same time, in this embodiment, refer again to Figure 5 As shown, as a preferred implementation form, the inner sealing ring 111 is arranged close to the clamping portion 10, and the distance between the outer sealing ring 112 and the lip 110 is greater than the distance between the outer sealing ring 112 and the inner sealing ring 111, so as to improve the sealing effect of the three.

[0048] In addition, combined Figure 2 and Figure 5 As shown, as a preferred implementation form, a limiting protrusion 101 is provided on the inner wall of the snap-in hole 100 of this embodiment, and as the snap-in seat 2 is snapped into the snap-in hole 100, the limiting protrusion 101 presses against the snap-in seat 2 to limit the movement of the sealing gasket relative to the snap-in seat 2.

[0049] It can be understood that by providing the limiting protrusion 101 that is clamped on the buckle seat 2, the sealing gasket can be squeezed into contact with the inner wall of the buckle seat 2 to prevent the sealing gasket from falling off, thereby enhancing the connection strength between the sealing gasket and the buckle seat 2.

[0050] Furthermore, the number and arrangement of the limiting protrusions 101 of the present embodiment can be set and adjusted according to actual snap-in requirements. For example, there can be four of them arranged at intervals along the circumference of the sealing gasket, so as to improve the snap-in stability between the sealing gasket and the buckle seat 2 while ensuring the convenience of the snap-in between the two.

[0051] The sealing gasket of this embodiment is capable of forming multiple seals by providing a plurality of annular sealing structures on one side of the gasket body 1 for sealing, so as to improve the sealing effect between the buckle and the plate body, thereby enhancing the waterproof performance, thereby improving the quality of vehicle interior and enhancing customer experience.

[0052] Embodiment 2

[0053] This embodiment relates to a buckle, such as Figures 3 to 6 As shown, it includes a buckle seat 2 for connecting the first plate body and the second plate body, and the buckle also includes the above-mentioned sealing gasket.

[0054] To elaborate, as an exemplary structure, the buckle seat 2 of this embodiment includes a base plate 20 , a claw 21 disposed on one side of the base plate 20 , and a connecting column 22 disposed on the other side of the base plate 20 .

[0055] The connecting column 22 is provided with an annular first slot 221 and a second slot 222 at intervals, the first slot 221 is adjacent to the base plate 20, the sealing gasket is clamped in the first slot 221, and the second slot 222 is used to clamp the buckle seat 2 onto the first plate body. At the same time, the second plate body is clamped between the claw 21 and the base plate 20, and the sealing gasket is pressed against the second plate body.

[0056] Furthermore, when the sealing gasket of the present embodiment is clamped in the first clamping groove 221, the clamping portion 10 is clamped in the first clamping groove 221. At this time, the limiting protrusion 101 is pressed against the groove wall of the first clamping groove 221. It can be understood that in the radial direction of the sealing gasket, a gap is formed between the hole wall of the clamping hole 100 and the groove wall of the first clamping groove 221 except for the limiting protrusion 101. The advantage of such an arrangement is that it is conducive to the clamping operation between the sealing gasket and the buckle seat 2, and can ensure the clamping stability between the two.

[0057] In addition, the present embodiment also relates to a vehicle door, such as Figure 7 and Figure 8 As shown, the vehicle door is provided with the above-mentioned buckle, and the vehicle door trim panel 3 constitutes a first plate body, and the vehicle door inner panel 4 constitutes a second plate body, so as to improve the sealing and waterproof effect of the vehicle door interior trim panel assembly.
