The invention relates to a battery and vehicle body battery integrated safety structure. Comprising a vehicle body passenger compartment and a power battery box body, the power battery box body is arranged below a passenger compartment of a vehicle body; a front-row seat cross beam is arranged above the middle part of the floor of the vehicle body passenger compartment; a power battery cross beam is arranged in the middle of the power battery box body; the front-row seat cross beam and the power battery cross beam are rigidly connected together to form a double-cross-beam structure, and the double-cross-beam structure and B columns on the two sides of a vehicle body jointly form a cage type structure. Mounting points connected with a floor of a passenger compartment of a vehicle body are arranged on the two side surfaces, the front part, the rear part and the center of the box body of the power battery box body. The internal cross beam of the battery pack is connected with the cross beam of the front seat of the automobile body, the two cross beams are overlapped and form a cage type structure with the B column of the automobile body, the integration degree of the power battery of the electric automobile and the automobile body is improved, the cross beam with higher strength can simplify the structural design of the doorsill beam of the automobile body, the weight of the whole automobile is reduced, and the safety performance is greatly improved.
本发明是一种电池车身电池一体化安全结构。包括车身乘员舱和动力电池箱体;所述动力电池箱体设置在车身乘员舱下方;所述车身乘员舱的地板中部上方有前排座椅横梁;所述动力电池箱体的中部设置有动力电池横梁;所述前排座椅横梁和动力电池横梁刚性连接在一起构成双横梁结构,并于车身两侧B柱共同构成笼式结构;所述动力电池箱体的两个侧面、前部和后部以及箱体中央均设置有与车身乘员舱的地板相连的安装点。本发明将电池包内部横梁与车身前排座椅横梁相连接,两道横梁重叠,同时与车身B柱形成笼式结构,提高电动汽车动力电池与车身的集成度,强度更高的横梁可以简化车身门槛梁的结构设计,降低整车重量,并大幅提升安全性能。
