AI Technical Summary
Traditional car window regulator cables are prone to oxidation and rust during use, leading to increased friction resistance, which affects user experience and safety. They also require regular application of lubricant to maintain lubrication, resulting in higher costs.
Oil reservoirs and oil dispensing mechanisms are installed at both ends of the guide rail groove. When the bracket approaches the oil reservoir, the oil dispensing mechanism causes lubricating oil to be sprayed onto the sponge in a measured amount. During the sliding process of the cable, the sponge provides continuous lubrication, ensuring a long-term lubrication effect.
Automatic lubrication of the cables was achieved, reducing maintenance frequency and costs, and improving the smoothness of operation and service life of the window regulator.
