Product Function & Role

What is the Core Function of the Left Rear Door Assembly?

• Rear occupant access: The left rear door is the primary access route for left-side rear occupants, with a wide opening angle for easy entry and exit.

• Side collision protection: Built-in side impact beams effectively absorb and disperse impact energy during side collisions, protecting the passenger cabin. As the first line of defense on the vehicle side, the door is critical to occupant safety.

• Window operation and ventilation: Integrated power window system with one-touch operation for convenient cabin ventilation. 4-door soundproof/heat-insulating glass enhances cabin quietness and comfort.

• Electric suction door function: The door features electric suction function—just push it close to the frame and the mechanism automatically pulls it shut, eliminating the need for forceful closing, enhancing convenience and premium feel.

• Interior carrier and function integration: The inner door panel carries interior components including trim, speakers, and storage pockets, while integrating door latch, handles, window regulator, and check.
