The invention discloses a side wall assembly and a vehicle body structure. The side wall assembly comprises a column A reinforcer assembly, a column A upper reinforcer assembly, a column B 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, one end of the B column reinforcer assembly is connected with the A column upper reinforcer assembly, and the other end of the B column reinforcer assembly is connected with the side wall doorsill reinforcer assembly. The reinforcing ring structure is divided into a front door opening reinforcing ring structure and a rear door opening reinforcing ring structure. The side wall assembly has the advantages that transmission of collision force borne by the side wall assembly is guaranteed, the collision performance of the side wall 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 then the weight of the side wall assembly is reduced.
本发明公开了一种侧围总成及车身结构,包括A柱加强件总成、A柱上加强件总成、B柱加强件总成、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B柱加强件总成一端连接A柱上加强件总成,另一端连接侧围门槛加强件总成,致使加强环结构分为前门洞加强环结构和后门洞加强环结构。本发明的优点在于,保证侧围总成所受的碰撞力的传递,提高了侧围总成的碰撞性能,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,进而减轻侧围总成的重量。
