[0002] The A-pillar is a vertical column located on either side of the windshield, between the engine compartment and the passenger compartment, connecting the roof and the body of the vehicle. It is usually a vertical or nearly vertical columnar structure, sometimes with an A-shape, hence the name.

[0003] Currently, car doors sink after being installed on the vehicle body due to the influence of gravity. When a downward force is applied to the door, the amount of sinking will be even greater. If the door sinks too much, it will affect the opening and closing of the door and may even cause damage to the door over time. Utility Model Content

The outer wall of the manganese steel plate is fixedly connected with a glass fiber layer, the outer wall of the glass fiber layer is fixedly connected with a protective layer, and the inner wall of the manganese steel plate is fixedly connected with a titanium steel inner plate.

[0008] According to the automobile A-pillar lower reinforcement, the support base and the support arch are manufactured using an integrated molding technology, thereby improving the overall structural strength of the reinforcement.

[0009] According to the automobile A-pillar lower reinforcement, the supporting frame and the right side wall of the connecting side plate are fixedly connected with a side sealing plate, thereby improving the overall structural strength of the supporting frame, the connecting side plate and the side sealing plate.

[0010] According to the automobile A-pillar lower reinforcement, the connecting side panel and the matching side panel cooperate with each other, thereby improving the stress condition at the connection between the connecting side panel and the matching side panel.
