The invention discloses a side wall front door opening assembly and a vehicle body structure. The side wall front door opening assembly comprises an A column reinforcer assembly, an A column upper reinforcer assembly, a B column reinforcer 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 B column reinforcer assembly and the side wall doorsill reinforcer assembly are connected to form a closed reinforcing ring structure, the doorsill reinforcing beam assembly is arranged in the side wall doorsill reinforcer assembly, and the B column reinforcer assembly is connected with the A column upper reinforcer assembly and 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 B-column reinforcer assembly and the doorsill reinforcing beam assembly. The side wall front door opening assembly has the advantages that transmission of collision force borne by the side wall front door opening assembly is guaranteed, the collision performance of the side wall front door opening assembly is improved, the safety performance of a vehicle body is improved, the original structural strength and performance can be met through the small section size, and the weight of the side wall front door opening assembly is reduced.

    本发明公开了一种侧围前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、B柱加强件总成、门槛加强梁总成、侧围门槛加强件总成;A柱加强件总成、A柱上加强件总成、B柱加强件总成、侧围门槛加强件总成连接形成封闭的加强环结构,门槛加强梁总成设置在侧围门槛加强件总成内部,B柱加强件总成连接A柱上加强件总成和侧围门槛加强件总成;A柱加强件总成、A柱上加强件总成、B柱加强件总成、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,保证侧围前门洞总成所受的碰撞力的传递,提高侧围前门洞总成的碰撞性能,提高车身安全性能,较小的截面尺寸就可以满足原有结构强度和性能,减轻侧围前门洞总成的重量。
