The invention discloses a vehicle body side collision energy absorption structure of an electric vehicle in the technical field of vehicle body energy absorption, which comprises a B column main body consisting of a B column body, a lower support plate and an upper support plate; the energy absorption shell is arranged in the center of one side of the B main body; a hole site protection assembly, wherein the hole site protection assembly is arranged corresponding to the flat cable hole; the multiple sets of first auxiliary energy absorption assemblies are each composed of a mounting shell, multiple sets of expansion buffering mechanisms and a triggering part; and the multiple second auxiliary energy absorption assemblies are arranged, and each second auxiliary energy absorption assembly is composed of two extending energy absorption mechanisms and a driving mechanism. Through the design of the first auxiliary energy absorption assembly, the second auxiliary energy absorption assembly, the buffering assembly and the hole site protection assembly, the multi-layer buffering function with mutual compensation is achieved, and therefore the beneficial effects that the strength of the B column body is effectively improved, and collision force is effectively dispersed and reduced are achieved.

    本发明公开了车身吸能技术领域内的一种电动汽车的车身侧面碰撞吸能结构,包括:B柱主体,所述B柱主体由B柱本体、下支撑板和上支撑板组成;吸能壳,所述吸能壳设置于B主本体一侧中心;孔位保护组件,所述孔位保护组件与排线孔呈对应设置;第一辅助吸能组件,且多组第一辅助吸能组件均由安装壳、多组扩展缓冲机构和触发部件组成;第二辅助吸能组件,所述第二辅助吸能组件设置有多组,所述第二辅助吸能组件由两组延伸吸能机构和驱动机构组成。通过第一辅助吸能组件、第二辅助吸能组件、缓冲组件和孔位保护组件的设计,实现了多层且具备相互弥补的缓冲功能,从而有效的提高了B柱主体的强度以及有效分散消减碰撞力的优点。
