The electric vehicle battery integrated middle floor assembly comprises a doorsill beam, a plurality of floor cross beams and a battery pack, a battery pack frame is connected to the lower portion of the doorsill beam, a battery pack upper cover is used as a vehicle body middle floor, the vehicle body middle floor does not need to be specially configured any more, and the vertical size of the structure and the weight of the structure are reduced. An energy absorption aluminum box is arranged in the doorsill beam, the energy absorption aluminum box is divided into a plurality of cavities through a reinforcing plate structure, a box body top plate and a box body bottom plate of a box body are in a wave shape and are thinned in a segmented mode from outside to inside, transverse partition plates of the reinforcing plate structure are thinned in a segmented mode from outside to inside, and the wave-shaped structure is used for guiding compression energy absorption. The structure which is gradually thinned in sections is used for ensuring step-by-step compression energy absorption, the annular structure formed by the doorsill beam, the aluminum energy absorption box and the floor cross beam can ensure the overall rigidity requirement of the body in white and can also meet the energy absorption requirement in collision, and a battery cell structure is protected against invasion in the collision process.

    本发明公开了一种电动汽车电池集成一体化中地板总成,包括门槛梁、多条地板横梁和电池包,电池包框架连接在门槛梁的下方,电池包上盖作为车身中地板使用,无需再专门配置车身中地板,利于降低结构的竖向尺寸和减轻结构重量。在门槛梁中配置有吸能铝盒,吸能铝盒由加强板结构分隔出多个空腔,盒体的盒体顶板和盒体底板分别呈波浪形且从外向内分段变薄,加强板结构的横向隔板也从外向内分段变薄,波浪形结构用以引导压缩吸能,分段逐渐变薄的结构用于确保逐级压缩吸能,门槛梁、铝吸能盒、地板横梁组成的环状结构既可以确保白车身整体的刚度要求,也能满足碰撞中的吸能要求,保护电芯结构碰撞中不受侵入。
