The embodiments described below by referring to the drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1 to 4, the utility model provides an automobile, including installing sheet metal component 1, front deck plaque 2 and the front deck sealing member 3 in the front deck of automobile, sheet metal component 1 includes a body coupling's curb plate 11 and extends to front deck plaque 2 below and can support by curb plate 11 bottom plate 12 of front deck sealing member 3.

Automobile forecabin sealing member 3 is including sealing connection in the sealing member body 31 between forecabin plaque 2 and sheet metal component 1, sealing member body 31 is including pressing from both sides and locating forecabin plaque 2 with sheet metal component 1 but between the bottom plate 12 and elastic deformation support tight portion 311, be equipped with inside flanging 13 on the sheet metal component 1, one side that sealing member body 31 kept away from to tight portion 311 is equipped with and to hook and locate hook portion 32 on the inside flanging 13.

When being connected with front deck plaque 2 and sheet metal component 1, put into between front deck plaque 2 and sheet metal component 1 through the portion 311 that supports with sealing member body 31, realize sealing connection when utilizing front deck plaque 2 and sheet metal component 1 to carry out the centre gripping to the sealing member, the inside flanging 13 of sheet metal component 1 is located to the hook of borrowing hook portion 32 again, thereby realize the fixing of sealing member and front deck plaque 2 and sheet metal component 1, need not to fix with the help of the screw, reduce the installation part, the assembly is simple, promote assembly work efficiency.

Further, the elastic deformation amount of the abutting portion 311 sandwiched between the sheet metal part 1 and the front cabin trim panel 2 is 2-4mm, and in this embodiment, the elastic deformation amount is 3 mm. The elastic deformation amount generated between the sheet metal part 1 and the front cabin decorative plate 2 is clamped by the abutting part 311, so that a good sealing effect is achieved between the sealing element and the sheet metal part 1 as well as between the sealing element and the front cabin decorative plate 2, and meanwhile, the effect of fixing the sealing element is also achieved.

In this embodiment, the hook portion 32 is provided with an installation groove 321 into which the inward flange 13 can be inserted, the installation groove 321 faces obliquely upward, and in other embodiments, the installation groove 321 may also face laterally or directly upward. Further, the mounting groove 321 penetrates to both ends of the hook portion 32 in a length direction thereof.

Utilize the joint cooperation of installing groove 321 and the interior turn-ups 13 on the sheet metal component 1 on hook portion 32 to form vertical spacing to the sealing member, prevent that sealing member body 31 from keeping away from the one side perk that makes progress of supporting portion 311, make sealing member and sheet metal component 1 and front deck plaque 2 tightly laminate, reach sealed fixed effect.

Further, the top of the sealing element body 31 protrudes to form a limit boss 312 near the abutting portion 311. Through setting up spacing boss 312, when the portion 311 clamp of holding is located between bottom plate 12 and the front deck plaque 2 of sheet metal component 1, spacing boss 312 can form spacing joint effect with the lateral wall of front deck plaque 2, and the restriction sealing member moves towards front deck plaque 2 direction, has improved the assembly reliability of sealing member, further improves the sealed effect of sealing member.

In this embodiment, the side wall of one end of the sealing element body 31 protrudes outward to form a limiting step 313 which can be clamped and limited with the sheet metal part 1 along the length direction of the sealing element body 31.
