Description

Technical Field

[0001] The invention relates to a vehicle door structure, in particular to a vehicle door structure with a window frame hidden above a waistline of the vehicle door. Background Art

[0002] At present, due to the existence of the door window frame, the traditional framed car door has a relatively high door stiffness above the waistline. The window frame above the waistline and the door sealing surface below the waistline have a smooth transition, and sealing strips can be arranged on the window frame, so the sealing performance is excellent. However, due to the exposed window frame and the gap and step difference between the window frame and the glass, the appearance of the framed car door is not clean and smooth. The frameless car door has a clean and smooth appearance, but because there is no window frame, the sealing stiffness above the waistline is only provided by the glass, resulting in poor sealing stiffness above the waistline of the door, and a sharp transition between the door glass and the door sealing surface below the waistline. At the same time, more sealing strips cannot be arranged above the waistline of the frameless door, so the sealing effect is poor.

[0003] With the development of the automobile industry, customers are paying more and more attention to the side shape of the car door and the wind noise performance of the whole vehicle. To meet the needs of customers, most vehicle manufacturers have adopted frameless doors or framed zero-step difference designs. Frameless doors have the following disadvantages: 1. The glass of frameless doors has no window frame support. At high speeds, due to the difference in air pressure inside and outside the car, the door glass is easy to stretch outward and the glass shakes on bumpy roads, which makes the door sound insulation performance worse than traditional doors; 2. There is a natural design gap between the frameless door and the body sealing strip, and the risk of door leakage is high; 3. The design of the glass lifting system and sealing system of frameless doors is complex, 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 the door appearance not being clean and simple enough. 2. There are gaps and step differences between the window frame trim, window frame trim and glass, resulting in the door appearance not being smooth enough. This will cause more wind noise excitation.

[0004] Therefore, it is necessary to develop a door structure with hidden window frame that is low-cost, clean and smooth in appearance, and has excellent wind noise performance. To achieve a door structure with hidden window frame, how to achieve a structural integration of the advantages of framed door and frameless door structures is the key. Summary of the invention
