[0002] With the development of the automobile industry, customers are paying more and more attention to the side shape of car doors and the wind noise performance of the whole vehicle. Car doors are divided into framed doors and frameless doors. Although traditional framed doors have good sealing performance, there are steps between the side glass and the window frame, which makes the side appearance uneven and the wind noise performance is large. Although frameless doors have a smooth side appearance, the rigidity of the door above the waistline is poor due to the lack of window frames. Therefore, the door is easy to open outward during high-speed driving, resulting in increased wind noise. Moreover, after the door is closed, the gap between the door and the body cannot be completely sealed, resulting in poor sealing performance.
