B column structure for vehicle body and vehicle

Abstract

The invention belongs to the field of vehicle structures, and particularly relates to a B column structure for a vehicle body and a vehicle. The invention aims to solve the problem that when a B column structure of a traditional automobile encounters side collision, the lower end of a B column collapses, and the upper section of a B column inner plate is torn from a welding spot, so that the requirement of the safety performance of a vehicle body is difficult to meet. For the purpose, according to the B column structure for the vehicle body, the vehicle body comprises a top cover boundary beam inner plate, the B column structure comprises a B column inner plate and a reinforcing piece, and the reinforcing piece is fixedly connected with the top cover boundary beam inner plate and the B column inner plate. According to the B-pillar structure, the reinforcing piece is arranged at the joint of the top cover boundary beam inner plate and the B-pillar inner plate, when a vehicle encounters side collision, acting force borne by the reinforcing piece can be dispersed and transmitted to the top cover boundary beam inner plate and the B column inner plate, and thus acting force borne by the joint of the top cover boundary beam inner plate and the B column inner plate is effectively reduced; and the problem that the B column inner plate is torn from a welding spot when a vehicle encounters side collision can be effectively relieved.

Description

technical field [0001] The invention belongs to the technical field of vehicle structures, and in particular relates to a B-pillar structure for a vehicle body and a vehicle. Background technique [0002] At present, with the development of the times and the advancement of science and technology, the number of new energy vehicles is increasing. New energy vehicles have the characteristics of saving fuel energy, reducing exhaust emissions, and protecting the environment, and have good development prospects. [0003] Compared with traditional cars, the big difference between new energy vehicles and traditional cars is that new energy vehicles need to carry heavier battery packs, and some battery packs can weigh up to 500-600KG, resulting in a significant increase in the weight of new energy vehicles. Therefore, correspondingly higher requirements are placed on the safety performance of the body of new energy vehicles. [0004] The B-pillar of a car is the pillar between the f...
