In the top area of the vehicle door, when the glass is matched with the vehicle body sealing strip, the vehicle door window frame is hidden behind the glass, so that the appearance of the frameless vehicle door is realized, and meanwhile, the performance of the framed vehicle door is also kept. The window frame hidden vehicle door structure is clean and simple in appearance, excellent in performance, low in cost and beneficial to large-scale popularization of the window frame hidden vehicle door structure.

Description

technical field [0001] The invention relates to a vehicle door structure above the waistline of the vehicle door, in particular to a vehicle door structure used in the top area of ​​the vehicle door to hide the window frame of the vehicle door. 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 pro...

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
