The invention relates to the field of car exterior trim panels, and more particularly to an exterior trim panel of a car door. The lower exterior trim panel of the car door comprises an exterior panel body and an interior panel body, wherein a compacting piece is arranged at the interior wall of the interior panel body; the interior panel body is connected with an interior panel extension part by a hinge; the exterior wall of the interior panel extension part is provided with an exterior fitting surface matched with the interior wall of the exterior panel body; the interior wall of the interior panel extension is provided with an interior fitting surface matched with the exterior wall of an exterior sheet metal panel; the interior panel body rotates around the interior panel extension part to obtain an open state and an assembling state; and a sheet metal overlapping area of the exterior sheet metal panel and an interior sheet metal panel are compacted on the interior fitting surface by the compacting piece at the interior panel body under the assembling state. The lower exterior trim panel of the car door accomplishes the assembling work by connecting the interior panel body to the interior sheet metal panel through an overturn structure after fixing and connecting the interior panel body with the exterior panel body through the extension part. The requirements of fitting between the exterior panel and car body sheet metal can be ensured without the need for special tooling and accessories in the assembling process, thereby greatly improving the assembly efficiency and reducing production costs.
Description
technical field [0001] The invention relates to the field of vehicle exterior trim panels, in particular to a vehicle door exterior trim panel. Background technique [0002] In the prior art, the exterior trim panel at the lower part of the car door of the automobile is snapped together with the metal sheet through buckles, and the edge position of the exterior trim panel is bonded to the sheet metal and fixed by double-sided adhesive bonding. Since the material of the exterior decorative panel is a modified PP material, it will be deformed during production and transportation. In the assembly process, in order to ensure that the cooperation between the exterior trim panel and the sheet metal parts reaches zero gap, it is necessary to use double-sided tape with strong adhesive force, and apply a pressure of more than 50N to make the adhesive tape and the sheet metal parts Adhesive force reaches the range of use permit. Because the doors are movable on the complete vehicle ...
