What does 'pull' mean on the windshield wiper?

[DelEvangeline]

The 'pull' function on the windshield wiper means pulling it upward to automatically spray water and clean the front windshield. Below are the relevant explanations: 1. Introduction: The wiper, also known as the windshield wiper, is a device used to remove raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. 2. Operating Principle: The power source of the wiper comes from an electric motor, which is the core of the entire wiper system. The quality requirements for the wiper motor are quite high. It uses a DC permanent magnet motor, and the wiper motor installed on the front windshield is generally integrated with the worm gear mechanical part. The function of the worm gear mechanism is to reduce speed and increase torque. Its output shaft drives a four-bar linkage mechanism, which converts continuous rotational motion into left-right swinging motion.
