Description

technical field [0001] The invention relates to the technical field of wiper measurement, in particular to a device and method for measuring the rotation angle of a wiper arm. Background technique [0002] In the process of automobile research and development, the rotation angle of the wiper arm is a very important parameter, which affects the overall performance of the wiper. [0003] The current method of measuring the rotation angle of the wiper arm is as follows: mark the initial position of the wiper arm on the real vehicle, record it with an angle meter, remove the other wiper arm, and mark the wiper arm with the angle meter during the rotation of the wiper. The maximum position of the scraping wall, and finally measure the angle between the two marked positions on the front gear, which is the rotation angle of a wiper arm. [0004] This measurement method has poor accuracy and is prone to errors during the rotation of the wiper arm. Contents of the invention [00...
