[0002] As we all know, with the rapid development of the existing automobile industry, the safety performance of automobiles has attracted more and more attention from consumers and automobile manufacturers. As a key part of the automobile body structure, the A-pillar is not only related to the overall rigidity and stability of the vehicle, but also plays a key role in protecting the passenger compartment when the vehicle collides. Improving the safety performance of the A-pillar is of great significance to improving the safety performance of the entire vehicle.

[0003] The existing A-pillar of a passenger car has no auxiliary support device when in use. In a vehicle collision accident, the A-pillar is prone to deformation, which in turn affects the structural integrity of the passenger compartment and even threatens the safety of the occupants in the car, resulting in high limitations in its use. For this reason, we propose a new type of passenger car A-pillar protection bracket. Utility Model Content
