The invention discloses an electric automobile front floor structure and a lower automobile body with the electric automobile front floor structure, the electric automobile front floor structure comprises a left doorsill beam and a right doorsill beam, and a front floor beam support is fixed between the left doorsill beam and the right doorsill beam. According to the front floor structure designed by the invention, the side column collision resistance and the front offset collision resistance of a vehicle body and the structural strength of a panel in a driver and passenger pedal area are improved. The front floor, the front cabin and the rear floor are all manufactured and formed through the high-pressure vacuum casting process, and an original lower vehicle body formed by welding a plurality of parts is simplified into an assembly structure with three parts. The lower vehicle body mechanism of the vehicle body composed of the front floor, the front cabin and the rear floor which are integrally cast can be ingeniously fused with the CTB battery box, and the technical effects that the technology is simplified, safety is high, and the whole vehicle is light in weight are achieved.

    本发明公开了一种电动汽车前地板结构及具有该结构的车身下车体,包括左门槛梁和右门槛梁,所述左门槛梁和所述右门槛梁之间固定有前地板梁支架。本发明所设计的前地板结构提升了车身的侧面柱碰撞耐撞性、正面偏置碰撞耐撞性和驾乘人员踏脚区域面板的结构强度。前地板、前舱和后地板均采用高压真空铸造的工艺制造成型,将原本众多零部件焊接而成的车身下车体简化为三个零部件的组装结构。一体化压铸的前地板、前舱和后地板组成的车身下车体机构能与CTB电池箱巧妙地融合到一起,达到了工艺简化、安全性高、整车轻量化的技术效果。
