The vehicle body can be roughly divided into an engine compartment, a passenger compartment and a luggage compartment, and the main stressed components are four-beam six-column, namely two front longitudinal beams, two rear longitudinal beams, two A columns, two B columns and two C columns. The A column, the B column and the C column of the vehicle are important components of a passenger compartment of a load-bearing vehicle body and are main stress components on the vehicle, so that high design requirements are imposed on the A column, the B column and the C column.

The a-pillar is a pillar on both sides of the front windshield, and is located between the engine compartment and the passenger compartment. In addition to the function of connecting the roof and the door, the a-pillar of the vehicle plays a very important role in protecting the passenger compartment from deformation and preventing the intrusion of wheels, suspensions, and the like into the passenger compartment during a frontal collision at the front of the vehicle.
