The electric automobile front floor structure comprises a front floor, two threshold inner plates, two threshold stiffening beam assemblies and a seat rear cross beam, the threshold inner plates extend in the vertical direction and are located on the left side and the right side of the front floor respectively, and the two threshold stiffening beam assemblies are arranged on the threshold inner plates. The doorsill stiffening beam assembly comprises a stiffening beam and a supporting plate, the stiffening beam and the supporting plate are both installed on the end face, back to the front floor, of the corresponding doorsill inner plate and abut against the doorsill inner plate, and the front end of the supporting plate abuts against the rear end of the stiffening beam. The end, close to the front floor, of the stiffening beam is used for being in lap joint with the end, in the left-right direction, of the automobile front wall lower beam and the end, in the left-right direction, of the automobile middle floor extending beam, the seat rear beam is located on the front floor, and the two ends, extending in the left-right direction, of the seat rear beam are connected with the two threshold inner plates respectively. Through the arrangement, when the automobile is collided, the displacement of the reinforcing structure is reduced, so that the deformation of the battery pack is reduced, and the safety performance of the automobile is improved.
本发明公开一种电动汽车前地板结构及电动汽车,电动汽车前地板结构包括前地板、两个门槛内板、两个门槛加强梁总成和座椅后横梁,门槛内板沿上下向延伸,且分别位于前地板沿左右向的两侧,门槛内板的中部与前地板沿左右向的两端抵接,门槛加强梁总成包括加强梁和支撑板,加强梁与支撑板均安装于对应的门槛内板背向前地板的端面,且与门槛内板抵接,支撑板的前端与加强梁的后端抵接,加强梁靠近前地板的一端用于与汽车前围下横梁和汽车中地板延伸梁沿左右向的一端搭接,座椅后横梁位于前地板上,且沿左右向延伸的两端分别与两个门槛内板相接。这样的设置能够使汽车发生碰撞时,减少加强结构的位移,进而减少电池包的变形,提升车辆的安全性能。
