Window glass lifting system

Abstract

The invention discloses a window glass lifting system. The window glass lifting system comprises a window glass, a window glass lifter and two parallel guide rails. The window glass is in a double-curvature bent shape. Trajectories of the guide rails refer to rotating hook face spiral lines. According to the window glass lifting system, the trajectories of the guide rails are set to be the rotating hook face spiral lines, the window glass lifting trajectories are turned to be spiral lifting, the deviation of window glass movement and the rotating hook face is basically zero during theoreticaldesign, the deviation of the guide rail trajectories and the window glass edge is also basically zero, the effect that the key factors of lifting difficulties and failures for the window glass cannotoccur is guaranteed, and the lifting movement requirements of the double-curvature bent shape glass are met.

Description

technical field [0001] The invention relates to the field of vehicle window glass lifting trajectory control, in particular to a vehicle window glass lifting system. Background technique [0002] Cars include front windows, rear windows and side windows, where the glass of the front window and rear window is usually designed as a curved surface, and is embedded in the window frame through a sealing strip, or the curved glass is made with a special adhesive. It is fixedly pasted on the window frame, so the front window and rear window of the car cannot be opened and closed. But for the convenience of natural ventilation, the side window glass of the car usually needs to be lifted and opened and closed. [0003] Since the up and down movement of the door glass needs to run in the front and rear guide rails of the car door, the theoretical correctness of the trajectory of the guide rails directly leads to the key factors of whether there are difficulties and failures in the gl...

AI Technical Summary

Problems solved by technology

With the improvement of people's aesthetics, the glass of the car has a double-curvature curved shape, and the trajectory lines of the front and rear guide rails of the spiral door used for the single-curvature cylindrical glass surface cannot meet the requirements of the double-curvature curved glass.
