What are automotive electric suction doors?
Electric suction doors are a comfort and safety feature commonly found in luxury cars, which can be closed automatically when the doors are not fully closed, and the doors will automatically suction until they are fully closed to avoid safety hazards caused by unclosed doors.
The working principle of electric suction door
The electric suction door is also called a magnetic suction door. Mainly through the power on and off to control the closure of the door. Power on to generate magnetic force, the door closed. When the power is off, the magnetic force disappears and the door opens. The door frame (or the edge of the door panel) is equipped with an electromagnetic coil, when the door is opened, there will be current passing through the coil, thus forming an electromagnetic field. Thus, due to the magnetic force, the door is automatically sucked shut when the door is closed to a closer distance from the door frame.

From the outside of the car did not feel the sound of closing the door
The car is more closed, but outside the car is noisier, in fact, did not use much force, but the car resonance effect is relatively large, so you feel loud and harsh in the car.
Not familiar with different models of doors, closing strength can not be properly grasped
Maybe their doors are thicker and heavier, so it is customary to use the force of their own doors to close your car door, the effect is certainly not the same.

Hinge, limiter device damage
The door and the car connected to the place, there are hinges and limiters, if often drop the door, they will also be damaged.
