3、统出现以前一系列不同的方法都尝试过。最早 的雨刷设计是一个塑料刀片在挡风玻璃上手动旋转。虽然这使挡风玻璃变干净， 前方的视野变清晰，但操作者的手很快就累了，于是这种设计被放弃了。另一个 的设计是由一个真空驱动泵所引发的。 不幸的是这种设计被操作速度随车速改变 的事实所困扰。这次失败最终导致连接一个电机到雨刮臂，这种本质一直沿用到 今天。 关键词：关键词：雨刷；发明；电动雨刷； II Abstract The windshield wiper was first invented in 1910.

It was his shock at the danger of driving without seeing the road properly that brought about the birth of windshield wipers.But a number of differe

6、nt methods were tried before the motor-driven wiper systems we are familiar with today came about. The initial windshield wiper design was one in which a rubber blade on the windshield was rotated manually. While this allowed the windshield to be cleared and forward vision improved, the operator hand soon tired, and the design was abandoned. The next design was powered by a vacuum driven pump. Unfortunately this design was plagued by the fact that its speed of operation changed with the speed o
