Problems solved by technology

[0003] At present, the A-pillar of the vehicle body is usually connected to the longitudinal beam by a single-layer plate structure. One end of the single-layer plate is connected to the A-pillar of the vehicle body, and the other end is connected to the longitudinal beam; the connection strength and rigidity can be improved by increasing the material thickness of the body parts or using high-strength plates, but This will increase the weight and cost of the vehicle; moreover, this method does not form a better collision force transmission path, so it has little effect on increasing the side impact strength and the torsional stiffness of the vehicle body

Abstract

The invention relates to the technical field of body structures of cars, and discloses a vehicle body A-column bottom connection structure. The vehicle body A-column bottom connection structure is characterized by comprising a first connection plate, a second connection plate, a longitudinal beam, a vehicle body A-column and a cross beam which are connected into the shape of a box, wherein the front ends of the first connection plate and the second connection plate are fixedly connected with the longitudinal beam; the rear ends of the first connection plate and the second connection plate are fixedly connected with the body A-column; the top ends of the first connection plate and the second connection plate are fixedly connected with the cross beam. The connection structure is in the form of a torque box, thus the impact strength and torsional rigidity of joints are effectively improved, and the vehicle safety and comfort are enhanced.

Description

technical field [0001] The invention relates to the technical field of automobile body structures, in particular to a connection structure at the bottom of an A-pillar of a vehicle body. Background technique [0002] The A-pillar of the car body is the connecting column that connects the roof and the front cabin on the left or right front of the vehicle. The connection structure between the bottom of the A-pillar and the longitudinal beam directly affects the side impact of the car, so the connection structure needs to have sufficient strength; in addition, the stiffness of the connection structure between the bottom of the A-pillar and the longitudinal beam has a great influence on the overall torsional stiffness of the vehicle body. The torsional stiffness performance of the vehicle body is an important factor affecting the NVH comfort of the vehicle. Therefore, the connection structure at the bottom of the A-pillar of the vehicle body has an important impact on the safet...
