Automobile door frame sealing structure

Abstract

The invention provides an automobile door frame sealing structure. The collapse of a sealing strip lower straight section at a corner R can be reduced, the sealing effect of the sealing strip can be guaranteed, the sound leakage can be reduced, the compression amount of a sealing strip supporting frame structure can be reduced and the door opening and closing sound quality can be improved. The automobile door frame sealing structure comprises a sealing strip top straight section and a sealing strip lower straight section; the two ends of the sealing strip top straight section are connected with the sealing strip lower straight section through sealing strip connecting angles; the section of the sealing strip lower straight section comprises a triangular frame-shaped supporting part; the bottom edge of the triangular frame-shaped supporting part is connected with a sealing strip lower straight section clamping part; one end of the bottom edge of the triangular frame-shaped supporting part is transversely connected with a first sealing lip; and the two ends of the sealing strip lower straight section clamping part are respectively a first clamping convex part and a second clamping convex part.

Description

technical field [0001] The invention relates to the technical field of automobile body components, in particular to an automobile door frame sealing structure. Background technique [0002] With the development of the automobile industry and the improvement of living standards, more and more people use cars, and they pay more and more attention to the appearance of cars and the sound quality of opening and closing doors. As a car door frame sealing strip, it has a great influence on the closing and closing speed of the door, and is an integral part of the sound quality of the car door opening and closing. [0003] The existing car door frame sealing structure is also different according to the different door structures, and generally has the following forms: 1. Integral car door structure, mostly single-channel sealing, and the sealing strip is installed on the side wall, that is, the door opening seal However, there are also some models that increase the joint angle at the...

AI Technical Summary

Problems solved by technology

For existing models, the section of the lower straight section of the door frame seal strip is mainly sealed with a circular bubble tube. This circular bubble tube is very prone to collapse at the R corner of the door sheet metal, resulting in poor sealing and easy sound leakage; The compression of this structure is generally large, the energy of closing the door is large, and the sound quality of opening and closing the door is poor.

[0004] Existing car models in the form of compound doors add sealing strips for the shielding seams at the gap between the front and rear doors, which are mainly connected to the European-style guide grooves, and are clamped on the door sheet metal through a U-shaped frame; No occlusion, poor appearance
