AI Technical Summary
Traditional door anti-collision beam structures have limitations in absorbing and dispersing collision energy, making it difficult to meet increasingly stringent vehicle safety standards, and causing more serious injuries to occupants in side collisions.
Design a door anti-collision beam structure, including an anti-collision beam body, a first rib and a second rib arranged side by side to form a "目" shaped cross section, and connected by bolts and a fixing reinforcing plate, combined with structural adhesive to enhance the overall rigidity and stability.
It effectively reduces door deformation, improves vehicle passive safety performance, significantly enhances impact resistance, protects the safety of occupants, and reduces side collision injuries.
