The drive motor is connected to the speed reducer, and the output shaft of the speed reducer is provided with a guide wheel. The guide rope includes an upper guide rope and a lower guide rope. One end of the upper guide rope is connected to the guide wheel, and the other end is connected to the upper end of the glass lifter bracket. One end of the lower guide rope is connected to the guide wheel, and the other end is connected to the lower end of the glass lifter bracket. The guide rope is usually made of steel wire cable, which has high strength and durability and can meet the mechanical requirements in daily use. However, in actual use, the steel wire cable is easily affected by environmental factors such as humidity and salt spray, leading to surface oxidation and rust. The rusty cable produces frictional resistance when the guide wheel rotates, making the glass lifting action become stuck, and even unable to lift normally. This not only affects the user's experience, but also may pose a potential threat to driving safety. To solve this technical problem, lubricating oil or grease is usually applied to the surface of the cable to reduce friction and rust. However, this application method cannot guarantee long-term lubrication, and regular maintenance and high cost are required. In addition, the bracket cannot detect the limit position in real time during lifting, which means that when the bracket approaches the limit position, the system cannot timely perceive and take corresponding deceleration measures, resulting in hard collision between the bracket and the limiting mechanism. Such collision not only produces noise, but also may cause mechanical damage to the limiting mechanism and the bracket, affecting their service life.
