Details
Car back door sill is an important component in automotive engineering design. It is located at the bottom of the vehicle body, connecting the front and rear car bodies, and forming an important supporting part of the body structure. The back door sill is usually made of high-strength steel to ensure that it can effectively absorb the impact energy in the event of a collision and protect the safety of the occupants in the car. In addition to the safety function, the back door sill can also enhance the rigidity and stability of the overall body. In the design process, the rationality of the back threshold has a vital influence on the handling and comfort of the vehicle. In addition, the design of the back door sill must also consider the layout and installation of other components of the vehicle chassis. In short, the car back threshold is not only related to vehicle safety, but also related to the overall performance and comfort of the vehicle.
