[0018] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0019] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to the inner or outer contours of a component or structure itself. Furthermore, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same elements.

[0020] This disclosure provides a sealing device for a vehicle, comprising: a rigid sealing body 1 having a first surface and a second surface disposed opposite to the first surface; a snap-fit ​​structure 3 disposed on the first surface and protruding from the first surface; and a sealing ring 2 disposed at least partially circumferentially on the first surface and located outside the snap-fit ​​structure 3.

[0021] Through the above technical solution, the sealing body 1 is made of hard material, which is not easy to deform and prevents the sealing device from loosening. A sealing ring 2 is provided on the first surface of the sealing body 1 to seal the gap between the sealing body 1 and the sheet metal hole 61 on the body sheet metal 6. The sealing body 1 is further fixed by snapping the sheet metal hole 61 through the snap-fit ​​structure 3. It can ensure that the sealing body 1 is firm and reliable, does not loosen or fail even under strong water flow impact.

[0022] As an optional implementation method, such as Figure 1-2 and Figure 4-5 As shown, the snap-fit ​​structure 3 includes a connecting plate 31 and a snap-fit ​​tongue 32. The connecting plate 31 protrudes from the sealing body 1 and is used to extend into the interior of the sheet metal hole 61. The connecting plate 31 extends in the same direction as the inner wall of the sheet metal hole 61. The snap-fit ​​tongue 32 is located on the outside of the connecting plate 31 and has a gap between it and the sealing body 1. The snap-fit ​​tongue 32 is located on the outside of the connecting plate 31, that is, on the side closer to the side wall of the sheet metal hole 61, so as to snap-fit ​​with the sheet metal hole 61. For example, if the sheet metal hole 61 is a round hole, the connecting plate 31 is an arc-shaped plate. The connecting plate 31 extends into the sheet metal hole 61. The snap-fit ​​tongue 32 has a gap between it and the sealing body 1 so that the snap-fit ​​tongue 32 can extend to the side of the body sheet metal 6 away from the sealing body 1 and snap-fit ​​with the side wall of the body sheet metal 6. At this time, the body sheet metal 6 is snapped between the snap-fit ​​tongue 32 and the sealing body 1.

[0023] Optionally, such as Figure 1-2 As shown, multiple connecting plates 31 are spaced apart, and a reinforcing plate 4 is provided between two adjacent connecting plates 31 to form a retaining ring. The outer diameter of the retaining ring is the same as the inner diameter of the sheet metal hole 61. There is a gap 5 between the connecting plate 31 and the reinforcing plate 4. Multiple connecting plates 31 are provided, and each connecting plate 31 is provided with a retaining tongue 32, which can ensure that the sealing body 1 is fixed more firmly. A reinforcing plate 4 is provided between the connecting plates 31. The reinforcing plate 4 and the connecting plate 31 together form a retaining ring with an outer diameter that is the same as the inner diameter of the sheet metal hole 61. That is, the reinforcing plate 4 is an arc-shaped plate with an outer diameter that is the same as the connecting plate 31. In this way, the retaining tongue 32 can ensure the axial fixation of the sealing body 1, and the retaining ring can ensure the radial fixation of the sealing body 1, preventing the sealing body 1 from moving or loosening.

[0024] The connecting plate 31 is constructed as a rigid elastic plate. The rigidity of the connecting plate 31 allows it to be secured to the sheet metal hole 61, preventing the sealing body 1 from moving radially. In order to engage the latch 32 with the body sheet metal 6, the latch 32 extends beyond the sheet metal hole 61. Therefore, when the connecting plate 31 is inserted into the sheet metal hole 61, the connecting plate 31 needs to be bent inward so that the latch 32 can extend beyond the body sheet metal 6 into the sheet metal hole 61. Hence, the connecting plate 31 is constructed as an elastic plate.

[0025] Optionally, such as Figure 1 and Figure 5 As shown, the side of the latch 32 away from the connecting plate 31 is constructed as an inclined surface that gradually slopes from the end near the sealing body 1 towards the side near the connecting plate 31. In other words, the latch 32 is triangular in structure, with the side near the sealing body 1 being a flat surface and the outer side being an inclined surface. This way, when the latch 32 is inserted into the sheet metal hole 61, the inclined surface contacts the side wall of the sheet metal hole 61, making it easier for the latch 32 to enter. The flat surface engages with the side wall of the sheet metal hole 61, making the engagement more secure.

[0026] As an optional implementation method, such as Figure 1 and Figure 3-5 As shown, the sealing ring 2 is constructed as a sealing sleeve fitted on the outer edge of the sealing body 1. It is detachable and easy to replace and install. The inner opening 22 of the sealing sleeve has a receiving cavity 23 communicating with the opening 22. The sealing ring 2 has a receiving cavity 23 inside. The outer edge of the sealing body 1 extends into the receiving cavity 23. This allows at least part of the sealing ring 2 to be located on the side of the sealing body 1 close to the body sheet metal 6, so that the sealing ring 2 can seal the part between the sealing body 1 and the body sheet metal 6, and makes the connection between the sealing ring 2 and the sealing body 1 more secure.

[0027] Optionally, such as Figure 3 As shown, the edge of the opening 22 is provided with a notch 21. For example, multiple notches 21 can be provided along the circumference of the opening 22, making it easier for the sealing ring 2 to be fitted onto the outside of the sealing body 1.

[0028] As an optional implementation, the sealing body 1 is constructed of PP material, which is polypropylene, or plastic. The sealing body 1 is integrally injection molded, which is convenient to process and has high rigidity, ensuring that the sealing body 1 can withstand the impact of water flow from all directions and is not easy to loosen.

[0029] As an optional implementation, the sealing ring 2 is constructed of EPDM material. EPDM material is ethylene propylene rubber. Ethylene propylene rubber has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, and water vapor resistance. Moreover, rubber is a flexible material, which makes it easier to seal the gap between the sealing body 1 and the body sheet metal 6.

[0030] Another object of this disclosure is to provide a vehicle, including: a body sheet 6 having a sheet metal hole 61; and a sealing device for the vehicle, wherein the orthographic projection of the sealing body 1 in its thickness direction completely covers the sheet metal hole 61 to ensure that the sheet metal hole 61 is completely covered and sealed, the snap-fit ​​structure 3 extends into the sheet metal hole 61 and snaps into the body sheet 6, and the portion of the sealing ring 2 disposed on the first surface extends at least to the outside of the sheet metal hole 61 to seal the gap between the sheet metal hole 61 and the sealing body 1.

[0031] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0032] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0033] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
