This product is specifically designed for the door system of the BYD Qin Pro (including fuel version, DM dual-mode plug-in hybrid version, and EV pure electric version). It is a core actuating component that drives the window glass to rise and fall smoothly—the power window regulator assembly. As the "power heart" of the power window system, the window regulator consists of精密components including a drive motor, gear reduction mechanism, guide rails, and sliders, converting the rotational motion of the motor into linear movement of the window glass. It is a critical component ensuring smooth window operation, proper sealing, and driving comfort.

The BYD Qin Pro was officially launched in September 2018, designed by former Audi design director Wolfgang Egger, marking the first application of the "Dragon Face" design language on a sedan. The Qin Pro is available in fuel version and multiple new energy versions, with body dimensions of 4765mm × 1837mm × 1500mm and a wheelbase of 2718mm. As a core component of the door system, the window regulator directly affects the smoothness of window operation, noise control, and sealing performance. This product adopts a cable-type lift mechanism, consisting of a high-strength aluminum alloy guide rail, wear-resistant steel cable, precision engineering plastic slider, and high-torque permanent magnet DC motor, with a precision gear reduction mechanism converting high-speed motor rotation into smooth linear motion.

As a professional manufacturer of automotive door accessory parts, we develop and produce strictly according to BYD OEM technical standards, certified with IATF 16949 quality management system. The product passes rigorous durability tests, high-low temperature cycle tests, and salt spray tests, with OE numbers precisely matching the original vehicle for direct replacement of damaged or failed original power window regulator assemblies.
