The invention discloses a side wall door opening assembly and a vehicle body structure. The side wall door opening assembly comprises an A column reinforcer assembly, an A column upper reinforcer assembly, a side wall rear inner plate welding assembly, a doorsill reinforcing beam assembly and a side wall doorsill reinforcer assembly. The A column reinforcer assembly, the A column upper reinforcer assembly, the side wall rear inner plate welding assembly and the side wall doorsill reinforcer assembly are sequentially connected to form a closed reinforcing ring structure, and the doorsill reinforcing beam assembly is arranged in the side wall doorsill reinforcer assembly; and closed reinforcing pipes are arranged in the A column reinforcer assembly, the A column upper reinforcer assembly, the side wall rear inner plate welding assembly and the doorsill reinforcing beam assembly. The side wall door opening assembly has the advantages that the closed reinforcing ring structure is formed by the side wall door opening assembly, the bending resistance and the torsion resistance are good, the other layer of original structure is replaced with the closed reinforcing pipe, the weight of a vehicle body is greatly reduced on the premise that the collision performance is met, and the lightweight design is met.

    本发明公开了一种侧围门洞总成及车身结构,包括A柱加强件总成、A柱上加强件总成、侧围后内板焊接总成、门槛加强梁总成、侧围门槛加强件总成;所述A柱加强件总成、A柱上加强件总成、侧围后内板焊接总成、侧围门槛加强件总成依次连接形成封闭的加强环结构,所述门槛加强梁总成设置在侧围门槛加强件总成内部;所述A柱加强件总成、A柱上加强件总成、侧围后内板焊接总成、门槛加强梁总成中均设置有封闭的加强管。本发明的优点在于,本发明中侧围门洞总成形成封闭的加强环结构,抗弯性和抗扭性好,通过封闭的加强管代替了原有的另一层结构,在满足碰撞性能的前提下大大降低了车身重量,满足轻量化设计。
