1. Vehicle Door Structure
Generally speaking, the vehicle doors consist of outside plates, inside plates, window frames, glass
guide rails, hinges, locks and window accessories and so on. The inside door plates are equipped with
accessories including glass lifter, locks and so on. To secure the assembly, some parts of the inside
door plates need to be fortified. To increase safety level, the inner parts of the outside plates are usually
equipped with impact bars. The outside plates and inside plates are connected by flanging, adhesion,
seam welding and so on. Depending on different bearing capabilities, the outside plates should be light
and the inside plates should have higher rigidity and be able to stand stronger impact.
The BIW vehicle door assemblies have relatively fewer components, and usually consist of inside
plates, outside plates, glass guide rails, window frame reinforcing plates, lock mounting plates, hinges
reinforcing plates, impact bar assemblies and so on; The figure below is a typical structure drawing of a
vehicle door.
