This paper introduces the classification and application of the wiper transmission mechanism,and then introduces how to use the geometric method to calculate the size and swing angle of the spatial four-bar linkage.In this paper,the kinematic characteristics of two types of mechanisms commonly used in wiper systems,series and parallel,are analyzed.It is determined that the minimum impact force ratio and the minimum transmission angle ratio are the optimization targets.The CATIA parametric calculation model is created,and then the two types of spatial four-bar linkage are optimized for size.Thereby,the impact force on the transmission mechanism during the operation of the wiper system is reduced,and the operating life and comfort of the wiper system are improved.
