The invention discloses a portable electric four-wheeler chassis which comprises two longitudinal beams distributed in a bilateral symmetry mode. The front face and the rear face of the longitudinal beam are perpendicularly connected through a front cross beam and a rear cross beam respectively. The front cross beam and the rear cross beam are in a rectangular frame shape, and the longitudinal beams are connected to the lower portions of the front cross beam and the rear cross beam. A front support arm and a rear support arm are arranged on the longitudinal beam; one ends of the front supportarm and the rear support arm are respectively connected to the upper parts of the front cross beam and the rear cross beam, and the other ends are bent downwards to be connected with the longitudinalbeams; and panel layers are laid on the longitudinal beams and the rear supporting arms. Battery boxes are arranged at the positions, corresponding to the front two rows of seats, on the panel layers.The chassis is reasonable in structure, by arranging the frame-shaped front cross beam, the frame-shaped rear cross beam, the front supporting arm and the rear supporting arm, the structural strengthof the chassis is improved, personnel and batteries on a vehicle are better protected when collision and scraping happen, the batteries are pushed, pulled, taken and placed in the battery box, a seatdoes not need to be moved, bolts do not need to be detached, and the defects of a portable electric four-wheeler chassis in the prior art are effectively overcome.

    本发明公开了一种轻便式电动四轮车底盘,它包括两根左右对称分布的纵梁;所述纵梁的前面和后面分别通过前横梁和后横梁垂直连结;所述前横梁和后横梁呈矩形框状,纵梁连接在前横梁和后横梁的下部;所述纵梁上设有前支臂和后支臂;所述前支臂和后支臂的一端分别连接在前横梁和后横梁的上部,另一端弯折向下与纵梁连接;所述纵梁和后支臂上铺设有面板层;所述面板层上在前两排座位对应处设有电池盒。本发明结构合理,通过设置框形前、后横梁以及前、后支臂,提高了底盘的结构强度,在发生碰撞刮擦时更好的保护车上人员,电池在电池盒中推拉取放,无需移动座椅和拆卸螺栓,有效的解决了现有技术中轻便式电动四轮车底盘的不足。
