The invention relates to the technical field of electric automobiles, and discloses a rear structure of an electric four-wheel drive automobile and the electric automobile. Longitudinal beams are arranged on the two sides of the bottom of a rear bottom plate body, and the front ends of the longitudinal beams are connected through a first rear floor cross beam; the two longitudinal beams close to the rear ends are connected through a rear floor second cross beam; the storage battery system and the CDU system are installed on the rear floor body, and the storage battery system is located above the second cross beam of the rear floor; the CDU system is located on the front side of the storage battery system. The CUD system is arranged in front of the storage battery system, so that the safety distance between the CUD system and the rear wall is increased, and the safety problem of high-speed electric shock of the rear part is solved; by arranging the second cross beam of the rear floor, the overall modal rigidity performance level of the rear floor structure is improved, the storage battery system is arranged above the second cross beam of the rear floor, the modal performance of a storage battery is improved, and the CUD system is further protected.

    本发明涉及电动汽车技术领域,公开了一种电动四驱汽车的后部结构及电动汽车,后底板本体底部两侧设有纵梁,纵梁前端之间通过后地板第一横梁连接;两纵梁靠近后端位置通过后地板第二横梁连接;蓄电池系统和CDU系统安装在后地板本体,蓄电池系统位于后地板第二横梁上方;CDU系统位于蓄电池系统前侧;本发明将CUD系统布置在蓄电池系统的前方,增大了与后围的安全距离,解决了后部高速碰电安全问题;通过设置后地板第二横梁,提高后地板结构整体的模态刚度性能水平,并将蓄电池系统布置在后地板第二横梁上方位置,提高了蓄电池模态性能,进一步保护了CUD系统。
