The door on the car is generally composed of three parts: the door body, the door accessories and the interior cover.
Shunt-opening door: It can be closed by the pressure of airflow even when the car is running, which is safer and convenient for the driver to observe backwards when reversing, so it is widely used.
Reverse-opening door: If the car is not closed tightly, it may be swept away by the oncoming air flow, so it is used less. Generally, it is only used to improve the convenience of getting on and off and meet the needs of welcome etiquette.
Horizontal moving door: its advantage is that it can still be fully opened when the distance between the side wall of the body and the obstacle is small.
Lift-up door: widely used as the rear door of sedans and light buses, and also used in low-profile cars.
Folding doors: are widely used in large and medium-sized passenger cars.
