[0018] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 and 2 As shown, this embodiment discloses a vehicle sealing strip, including a clamping part 1 and an elastic sealing part 2. The elastic sealing part 2 is disposed on the top of the clamping part 1. The clamping part 1 clamps and cooperates with the body sheet metal parts. The clamping part 1 is U-shaped and includes a skeleton 101 and a rubber covering part 102 covering the outside of the skeleton 101. The skeleton 101 includes a metal strip keel 101-1, and the strip keel 101-1 is provided with a plurality of resin U-shaped teeth 101-2 along the length direction.

[0020] One outer side of the covering portion 102 is provided with an outer sealing lip 102-1, and an inner side of the root of the outer sealing lip 102-1 is provided with a secondary sealing lip 102-3, the extension direction of the secondary sealing lip 102-3 facing the outer sealing lip 102-1. The other outer side of the covering portion 102 is provided with an interior overlapping lip 102-2, which is C-shaped. Clamping feet 102-4 are provided on the two inner walls of the covering portion 102, the extension direction of the clamping feet 102-4 being opposite to the opening direction of the clamping portion 1.

[0021] The elastic sealing part 2 has a hollow structure, and a sealing tongue 201 is provided on the top of the elastic sealing part 2, with the sealing tongue 201 facing the side where the outer sealing lip 102-1 is located. The elastic sealing part 2 is made of expanded polytetrafluoroethylene.

[0022] like Figure 3 As shown, taking the sealing of the tailgate assembly and the vehicle body as an example, in actual use, the U-shaped clamp of the clamping part 1 is directly clamped onto the body sheet metal part 4, and the clamping feet 102-4 on the two inner walls of the covering part 102 abut against the body sheet metal part 4; at the same time, the outer sealing lip 102-1 and the secondary sealing lip 102-3 on the outer side of the covering part 102 abut against the body sheet metal part 4, which plays a role in sealing and waterproofing; the interior overlapping lip 102-2 on the other side of the covering part 102 abuts against the interior panel 5 upwards, and when the tailgate is closed, the inner door panel 6 on the tailgate abuts against the elastic sealing part 2.

[0023] In this embodiment, a sealing layer 3 is provided at the bottom of the U-shaped clamp of the clamping part 1. When the body sheet metal part 4 is inserted into the U-shaped clamp of the clamping part 1, the edge of the body sheet metal part 4 is embedded in the sealing layer 3.
