AI Technical Summary

Technical Problem

Existing automotive sunroof guide rails are prone to deformation of the active guide block under prolonged use and high-temperature environments, resulting in poor limiting effect, uneven sliding, abnormal noise, and reduced lubrication, which affects the normal opening and closing of the sunroof.

Method used

The active guide block is smoothly decelerated by using the clamping friction between ceramic plates and friction plates. Combined with the innovative linkage design of sealing components and limiting units, the active guide block is smoothly decelerated by using the clamping friction between ceramic plates and friction plates. The release of lubricating fluid is automatically adjusted by using microporous copper-based gaskets to ensure smooth sliding and sealing.

Benefits of technology

The problem of deformation and poor limiting effect of the active guide block has been solved, enabling smooth opening and closing of the sunroof, enhancing sealing and lubrication, and reducing operating costs.

Abstract

本发明涉及具有限位功能的高紧密性汽车天窗导轨,且涉及汽车天窗系统的技术领域;其包括汽车车顶开设的窗口,汽车车顶设有与窗口相连的活动槽,活动槽内设有控制窗口开合的被动导轨,被动导轨上还滑动设有位于活动槽内的主动导块,被动导轨的两侧分别设有密封部件以及限位部件,通过密封部件来提高汽车车顶窗口与导轨上设置的玻璃之间的密封性,通过限位部件来实现汽车天窗导轨移动的距离;限位部件通过陶瓷片与摩擦片的夹持摩擦实现主动导块的平滑减速,彻底解决了传统硬性止挡的刚性碰撞问题,避免主动导块在碰撞时发生变形堵塞被动导轨而无法移动的情况。
