Description

Technical Field

[0001] This utility model relates to the field of glass lifting technology, specifically a lightweight guide rail glass lifting device. Background Technology

[0002] The power window regulator is an important component of a car. It is responsible for raising and lowering the door windows and plays an irreplaceable role in the comfort and stability of the car, sound insulation, and reduction of driving noise.

[0003] Common glass lifting devices typically consist of glass guide rails, motors, reducers, steel wire ropes, winches, guide plates, and glass mounting brackets. When the motor rotates in the forward direction, it drives the reducer and winch to rotate, which in turn moves the steel wire ropes and guide plates. Through the figure-eight cross-arm structure of the steel wire ropes, the glass can be moved up and down along the slide rails.

[0004] However, traditional window lift devices have a complex structure, with a large winch and a long steel cable requiring a figure-eight crossing, resulting in a heavy overall weight. When the vehicle travels on bumpy roads, the weight can cause the guide rails to loosen, affecting the safety of the glass. Therefore, those skilled in the art have provided a lightweight guide rail window lift device to solve the problems mentioned in the background. Utility Model Content
