Vehicle door structure with hidden window frame

Abstract

The present invention relates to a vehicle door structure with a hidden window frame, a vehicle door glass lifting guide rail is set on a door window frame, is disposed on the inner side in the vehicle width direction of a glass end on one side in the vehicle front-rear direction of the door glass, and extends in the vehicle up-down direction; a vehicle door glass lifting sliding block is fixed to the inner side surface of the end of the vehicle door glass in the vehicle width direction through glue, the vehicle door glass lifting sliding block and the vehicle door glass form a structure with an opening in one side in the front-back direction of the vehicle, and the opening structure is inserted into the vehicle door glass lifting guide rail. An assembly part formed by the vehicle door glass and the vehicle door glass lifting sliding block can be lifted along the vehicle door glass lifting guide rail; and a guide rail sealing strip and a glass guide groove sealing strip are arranged on the glass lifting guide rail. According to the structure, when the glass and the vehicle door window frame are connected and matched in the vehicle door B column area, the vehicle door window frame is hidden behind the glass, the appearance of a frameless vehicle door is achieved, and meanwhile the performance of a framed vehicle door is kept.

Description

technical field [0001] The invention relates to a car door structure, in particular to a car door structure above the waistline of the car door to realize the concealment of the car door window frame. Background technique [0002] At present, due to the existence of the door window frame, the traditional framed car door has relatively high door stiffness above the waistline, and the transition between the window frame above the waistline and the door sealing surface below the waistline is smooth, and sealing strips can be arranged on the window frame. Therefore, the sealing performance is excellent. However, because the window frame is exposed, and there are structural features such as gaps and steps between the window frame and the glass, the appearance of the framed door is not clean and smooth! Frameless doors have a clean, smooth appearance, but because there is no window frame, the sealing stiffness above the waistline is provided only by the glass, resulting in poor s...

AI Technical Summary

Problems solved by technology

Frameless doors have the following disadvantages: 1. The frameless door glass has no window frame support. At high speed, due to the difference in air pressure inside and outside the car, the door glass is easy to stretch out and the glass shakes on bumpy roads, which leads to poorer sound insulation performance of the door than traditional doors. ; 2. There is a natural design gap between the frameless door and the body seal, and the risk of door leakage is high; 3. The design of the frameless door glass lifting system and sealing system is complicated, and the cost is much higher than that of traditional doors

Framed doors have the following disadvantages: 1. The window frame, window frame trim, window frame trim, and sealing strip are exposed, resulting in a clean and simple appearance of the door

2. There are gaps and steps between the window frame trim, the window frame trim and the glass, which makes the appearance of the car door not smooth enough

so that there will be more wind noise excitation
