Description

Technical Field

[0001] This utility model relates to a car door glass lifting and sealing system, specifically a flush-type car door glass lifting and sealing system. Background Technology

[0002] With the development of the automotive industry, customers are paying increasing attention to the side profile of car doors and the overall wind noise performance of the vehicle. Car doors are structurally divided into framed doors and frameless doors. While traditional framed doors offer good sealing, the steps between the side glass and the door pillars create an uneven side profile and contribute to increased wind noise. Frameless doors, on the other hand, have a smooth side profile, but the lack of a window frame results in poor rigidity above the door's waistline. Therefore, during high-speed driving, the door is prone to outward expansion, increasing wind noise. Furthermore, the gap between the door and the body cannot be completely sealed when closed, leading to poor sealing performance.

[0003] To simultaneously meet customers' requirements for both styling and performance, it is necessary to develop a door structure that combines the sealing performance of a framed door with the smooth and streamlined appearance of a frameless door.

[0004] While existing automotive flush door systems achieve a flush appearance on the side of the door, they require high precision in the manufacturing and assembly of the door system components. This results in numerous and complex parts, difficulties in workshop assembly, high system costs, and the potential for issues such as window lifting. These problems have hindered the widespread adoption of flush door systems. Utility Model Content
