汽车窗升降器自锁条件及结构参数设计研究

Research on Self-Block Condition and Structure Parameter Design for Automobile Window Lifter

从密圈弹簧的本构关系分析车窗升降器的开启与自锁特征，揭示了自锁条件下结构本数设计规律，并用实例验证研究结论。

The unblocking and self-blocking characteristics of automobile window lifter are studied by making an analysis of the strain and stress of its screw spring.And disclosed is the law of the structure parameter design under the self blocking conditions.Examples are given to illustrate the conclusions drawn by the authors.
