Split-type glass guide rail structure for car door and fixing method thereof

Abstract

The invention discloses a split-type glass guide rail structure for a car door and a fixing method thereof. The split-type glass guide rail structure comprises an upper glass guide groove and a back guide rail, wherein an inserting groove is formed in the upper glass guide groove, and the top end of the back guide rail penetrates through the inserting groove and is matched with a metal plate hole in a metal plate of the car door. The fixing method of the split-type glass guide rail structure for the car door includes the steps: firstly, installing four-corner window glass on the back guide rail; installing the back guide rail and the four-corner window glass on the upper glass guide groove, wherein the back guide rail and the four-corner window glass are installed together; finally, clamping the back guide rail, the four-corner window glass and the upper glass guide groove together on the metal plate of the car door. The split-type structure of the upper glass guide groove, the back guide rail and the four-corner window glass of the car door is easy and convenient to assemble and clamp, installing quality is convenient to control, good appearance is guaranteed, parts are manufactured in a separated mode, precision is convenient to control, a rejection rate of finished products is reduced, and cost is low.

Description

technical field [0001] The invention relates to the technical field of automobile body accessories, in particular to a car door split glass guide rail structure and a fixing method thereof. Background technique [0002] Many car doors adopt the structure of fixed and sealed quadrangular windows with rear guide rails. The rear guide rail structure is generally "I"-shaped structure. There are two main ways to assemble quadrangular window glass and rear guide rail: 1. Square window glass and rear guide rail The guide rail is integrally molded, and then assembled to the upper part of the door as a whole; 2. The four-corner window glass and the rear guide rail are not integrally molded, the rear guide rail is assembled on the door first, and then the four-corner window is pushed in On the door, move the rear guide rail into the door along the glass guide channel. [0003] There are certain difficulties in the manufacture and installation of the two existing methods: the four-cor...

AI Technical Summary

Problems solved by technology

[0003] There are certain difficulties in the manufacture and installation of the two existing methods: the four-corner window glass and the rear guide rail are integrally molded, the cost and the precision of the mold are very high, it is difficult to control, and the product scrap rate is relatively high; during installation, whether it is Whether the rear guide rail is installed first or the four-corner window glass is installed first, the sealing strip must be pulled, resulting in a certain degree of deformation of the sealing strip, which affects the matching of the NVH performance of the vehicle and the appearance of the door
