Automobile B column reinforcing structure and automobile B column

Abstract

The invention relates to an automobile B column reinforcing structure and an automobile B column. The automobile B column reinforcing structure comprises a B column reinforcing plate, a B column roof side rail and a plurality of first supporting plates, and the B column roof side rail is connected to the top of the B column reinforcing plate; and the first supporting plates are assembled in a cavity of the B column roof side rail, and the first supporting plates, the B column roof side rail and the B column reinforcing plate jointly form a triangular stable structure used for increasing the top pressure value of a vehicle body in the connecting area of the B column roof side rail and the B column reinforcing plate. The first supporting plates can support a cavity of the B column roof side rail, so that the B column roof side rail is prevented from collapsing and deforming under the action force of collision, and the supporting strength of the B column roof side rail is enhanced; and the triangular stable structure can improve the overall strength and rigidity of the joint and the peripheral area of the B column reinforcing plate and the B column roof side rail, stress concentration deformation is prevented from being formed in the joint and the peripheral area, and therefore the jacking performance of the whole automobile body is improved, and the safety of passengers is improved.

Description

technical field [0001] The application relates to the technical field of the automobile industry, in particular to an automobile B-pillar reinforcement structure and the automobile B-pillar. Background technique [0002] At present, based on the popularization of global awareness of environmental protection and energy saving, the market has put forward higher requirements for the lightweight design of body-in-white. Consumers' demands on the safety performance of passenger cars and NVH-body vibration and noise control are also increasing, which makes it necessary to increase the rigidity of the vehicle structure while reducing the overall material thickness of the vehicle body. [0003] Safety performance is an important indicator of body-in-white performance, especially side impact and top pressure performance. Due to the small buffer area of ​​the side body structure, the side B-pillar structure of the body plays a vital role in the absorption and transmission of energy in...

AI Technical Summary

Problems solved by technology

[0005] The B-pillar reinforcement plate is the load-bearing beam between the front and rear rows of the car cockpit. It is connected to the top cover and the floor below. There are wiring harnesses passing through it. It is equipped with seat belt buckles and may even be installed with airbags. An important factor for the safety performance of the car body. In order to ensure safety, some manufacturers thicken the material and design it as a high-rigidity component. When the B-pillar reinforcement plate is subjected to a side collision, the deformation is small, and its top falls off from the roof of the car, causing occupants Injuried
