Core components and working principle of wiper

Power source: Driven by a DC permanent magnet motor, combined with a worm gear mechanism to reduce speed and increase torque, the rotational motion is converted into a swinging arm reciprocating scraping brush.

Scraper rubber strip: It needs to withstand at least 500000 scraping cycles, and the lip angle is precisely matched with the glass to improve cleaning efficiency.

Control unit: Control the sweeping cycle through intermittent relays, supporting multi gear adjustment such as low speed (LO), high speed (HI), intermittent (INT), etc.
