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.
本发明属于车辆结构领域,具体涉及用于车身的B柱结构及车辆。本发明旨在解决传统汽车的B柱结构遇到侧碰时,B柱下端会溃缩,B柱内板上段会从焊点的地方撕裂,因而难以满足车身安全性能的需求的问题。为此目的,本发明的用于车身的B柱结构,其中车身包括顶盖边梁内板,B柱结构包括B柱内板,B柱结构还包括加强件,加强件与顶盖边梁内板和B柱内板固定连接。本发明的B柱结构在顶盖边梁内板和B柱内板的连接处设置加强件,当车辆遇到侧碰时,加强件受到的作用力可以分散传递给顶盖边梁内板和B柱内板,从而有效降低了顶盖边梁内板和B柱内板的连接点受到的作用力,可以有效的缓解车辆遇到侧碰时B柱内板从焊点的地方撕裂的问题。
