Windshield Wipers
★Exhibit Content: Car Windshield Wiper ★Interaction: Electromechanical Interaction ★Operation: 1. Turn the handwheel to observe the wiping motion of the windshield wiper. 2. Press the "Display" button switch to observe the movement of the windshield wiper mechanism through the switchable privacy glass. ★Exhibit Description: The exhibit consists of two types of windshield wiper demonstration devices: opposed and facing. Each type of windshield wiper device includes two parts: a manual windshield wiper model and a liquid crystal glass device. Visitors can turn the handwheel to observe the wiping motion of the windshield wiper; by pressing the "Display" button switch, they can observe the movement of the windshield wiper mechanism through the switchable privacy glass. ★Scientific Principle: Why does the windshield wiper swing left and right when the handwheel is turned? The handwheel rotation replaces the power source of the windshield wiper, which comes from an electric motor, the core of the entire windshield wiper system. The windshield wiper motor installed on the front windshield is generally integrated with the worm gear mechanical part, and its output shaft drives a four-bar linkage mechanism, which converts continuous rotational motion into left-right swinging motion.
