Therefore, it is required that the A-pillar has a relatively small cross-section while achieving high strength and stiffness. Generally, methods such as designing the cross-sectional shape and using high-strength steel plates to improve the sheet metal strength are adopted to meet the requirements of high strength and stiffness of the A-pillar. With the control of automotive manufacturing costs by manufacturers and the requirements of consumers for the comprehensive energy consumption of automobiles, the traditional A-pillar structure has disadvantages such as high weight and high manufacturing costs.
