Triangle trim panel installation structure of automobile door

Abstract

The invention provides a triangle trim panel installation structure of an automobile door, which comprises an automobile door internal trim panel and a triangle trim panel. At least two circular posts are formed on the back surface of the triangle trim panel through injection. The automobile door trim, which corresponds to the posts on the back surface of the triangle trim panel, is provided with an installation hole. The installation hole is sleeved with a nylon retaining ring. The triangle trim panel on the automobile door internal trim panel is installed by interference fit between the posts and the nylon retaining ring. Moreover, a table top controlling an offset of the triangle trim panel and the assembling boundary conditions is arranged on the lower parts of the installation posts of the triangle trim panel. An upper plane of the table top is laminated with an end surface of the nylon retaining ring to control an assembly distance between the triangle trim panel and the automobile door internal trim panel. The triangle trim panel of the invention only needs two installation points to be fixed on the automobile door internal trim panel, and the automobile door triangle trim panel installation structure has simple structure and low cost and can guarantee appearance quality.

Description

technical field [0001] The invention belongs to the technical field of vehicle bodies, and in particular relates to a mounting structure of a triangular decorative panel on a door trim panel. Background technique [0002] The triangular trim on the door trim is located above the door trim to cover the mounting points of the exterior rearview mirrors from inside the vehicle. If the triangular trim panel and the door trim panel are integrated, the mold of the door trim panel will become complicated and the cost will increase, and the integral structure is also difficult to assemble on the assembly line. And if the triangular decorative panel is made into an independent piece, it needs to have a corresponding installation structure with the door trim panel. Now most installation structures are installed with plastic buckles, but the buckle seat must use a slider mechanism, which will make the mold more complicated. Sometimes, for a small-sized triangular decorative panel, ther...

AI Technical Summary

Problems solved by technology

Now most installation structures are installed with plastic buckles, but the buckle seat must use a slider mechanism, which will make the mold more complicated. Sometimes, for a small-sized triangular decorative panel, there are no more than two installation points for the buckle seat.

In addition, if the structural design of the installation point is unreasonable, there will be uneven gaps with the surrounding related parts, or the assembly is not firm, and the triangular decorative panel will shake or produce abnormal noise when the car is driving, or even fall off.
