[0010] Preferably, a sealing device for sealing the vehicle glass is provided on the door frame, and the sealing device is provided with a movable arc-shaped portion.

[0011] Also provided is a car, comprising the frameless door lightweight structure.

[0012] The beneficial effects of the utility model are as follows: the utility model effectively reduces the weight of the door system by 20% by adopting lightweight materials such as plastic and aluminum alloy, thereby achieving lightweighting of the vehicle. The "sandwich" structural design of the door outer panel, door frame and door interior ensures the structural stability and safety of the door. The plastic door outer panel and aluminum alloy door frame can maintain sufficient rigidity and strength when subjected to external forces. The plastic molding process has more diverse structures and appearances than steel stamping, providing more possibilities for the exterior design of the vehicle. By integrating millimeter-wave radar, electronic rearview mirror and self-priming lock, the safety performance of the vehicle is improved, and the vehicle's surrounding environment can be monitored and timely safety warnings can be provided.
