A car door c-pillar split seam sealing strip structure

Abstract

A car door C-pillar split sealing strip structure, including a sealing strip and a decorative panel, the sealing strip is located between the C-pillar high-gloss trim panel and the D-pillar high-gloss trim panel in the length direction of the vehicle body, and the sealing strip is connected to the The decorative panel is located inside the C-pillar high-gloss decorative panel in the width direction of the vehicle body, the decorative panel is attached to the inner side of the C-pillar high-gloss decorative panel, the sealing strip is clamped to the decorative panel, and the sealing strip At the same time, it offsets the door sheet metal, the C-pillar high-gloss trim and the D-pillar high-gloss trim. In the present invention, the sealing strip is firmly assembled on the decorative panel by providing a clamping part with a wide part and a narrow part on the sealing strip, which improves the sealing performance of the sealing strip and reduces the separation of the sealing strip from the decorative panel. risk, and solved the prolapse problem of the C-pillar seal.

Description

technical field [0001] The invention relates to the technical field of interior and exterior decoration of automobiles, in particular to a C-pillar seam sealing strip structure of a car door. Background technique [0002] In order to make the door C-pillar high-gloss injection molding trim panel (hereinafter referred to as the trim panel) visually flush with the D-pillar trim panel, the trim panel needs to be designed to be pressed on the water cut outside the door, which will cause the trim panel to be in line with the sheet metal and rear door The combination of multiple structures such as corner windows restricts the structure of the trim itself. On this basis, the production process of this type of decorative panel will further restrict the installation of the C-pillar joint sealing strip (hereinafter referred to as the sealing strip), making it difficult to install the sealing strip. [0003] At present, the common fixing method of the sealing strip is that the sealing...

Problems solved by technology

[0002] In order to make the door C-pillar high-gloss injection molding trim panel (hereinafter referred to as the trim panel) visually flush with the D-pillar trim panel, the trim panel needs to be designed to be pressed on the water cut outside the door, which will cause the trim panel to be in line with the sheet metal and rear door The combination of multiple structures such as corner windows restricts the structure of the trim itself

On this basis, the production process of this type of decorative panel will further restrict the installation of the C-pillar split sealing strip (hereinafter referred to as the sealing strip), making it difficult to install the sealing strip

[0003] At present, the common fixing method of the sealing strip is that the sealing strip is clamped and fixed with the square hole structure on the decorative plate through the mushroom head connection structure, but this kind of fixing method is easy to cause the sealing strip to not be installed in place or the sealing strip to fall out after installation when the space is insufficient. problem, and the mushroom head connection structure itself has a small amount of clamping interference, and it is difficult to install it in place during installation
