The invention discloses an electric vehicle body structure with a flat front floor and an installation method. The electric vehicle body structure comprises a vehicle body front floor and a flat battery pack structure. The whole vehicle body front floor is of a flat structure, thresholds are arranged on the left side and the right side of the vehicle body front floor, a seat front cross beam and a seat rear cross beam are arranged between the two thresholds, and the seat front cross beam and the seat rear cross beam are perpendicular to the thresholds and penetrate through the thresholds on the two sides. A left cover plate body and a right cover plate body are arranged at the front part of the seat front cross beam; a plurality of nuts are arranged on the front floor of the vehicle body in a projection welding manner so as to fix the flat battery pack structure; the front and rear seat cross beams penetrate through the left and right thresholds and are matched with an aluminum profile frame structure in the flat battery pack and extrusion aluminum profiles added on the two sides of the thresholds, so that the seat cross beams, the aluminum profiles on the two sides of the thresholds and the crisscrossed frame in the pack body can form an organic whole; the safety problems of side collision, column collision, front collision, top pressure and the like of the current electric vehicle are perfectly solved.

    本发明公开了一种电动车纯平前地板车身结构及安装方法,包括车身前地板和平板电池包结构;所述车身前地板整体为纯平结构,所述车身前地板的左右两侧设置有门槛,两门槛之间设置有座椅前横梁和座椅后横梁,座椅前横梁和座椅后横梁与门槛垂直设置并贯穿两侧门槛;座椅前横梁的前部设置有左盖板本体和右盖板本体;所述车身前地板上凸焊多个螺母,以固定所述平板电池包结构;本发明将前后座椅横梁贯穿至左右门槛,配合平板电池包内部铝型材框架结构和门槛两侧增加挤压铝型材,座椅横梁可与两侧门槛铝型材及包体内纵横交错的框架形成一个有机整体,完美解决当前电动车面临的侧碰、柱碰、前碰、顶压等安全问题。
