The invention relates to a battery pack mounting structure of an electric vehicle. The battery pack mounting structure comprises a pair of doorsill beams, a front baffle lower cross beam, a rear floor front cross beam and a connecting device; the front baffle lower cross beam is arranged at the front ends of the pair of doorsill beams, the rear floor front cross beam is arranged at the rear ends of the pair of doorsill beams, a placing part is formed among the pair of doorsill beams, the rear floor front cross beam and the front baffle lower cross beam, and a battery pack is arranged in the placing part; the connecting device is arranged on the doorsill beams and comprises a cylinder body, a closed air cavity and a mounting arm; the closed air cavity is arranged in the cylinder body, one end of the mounting arm is connected with the cylinder body, and the other end of the mounting arm is connected with the battery pack; when the battery pack is collided, the cylinder body moves towards the direction of the battery pack, and relative movement for compressing and closing the air cavity is generated between the cylinder body and the mounting arm. According to the technical scheme, the connecting device is arranged on the doorsill beams, and the impact force borne by the whole vehicle is buffered through the connecting device, so that the force is prevented from being transmitted to the battery pack, and the battery pack is prevented from being damaged.

    本发明涉及了一种电动汽车电池包安装结构,包括一对门槛梁、前挡板下横梁、后地板前横梁以及连接装置;前挡板下横梁设在一对门槛梁的前端,后地板前横梁设在一对门槛梁的后端,一对门槛梁、后地板前横梁以及前挡板下横梁之间形成放置部,电池包设置在放置部;连接装置设置在门槛梁上,连接装置包括缸体、封闭气腔以及安装臂;封闭气腔设置在缸体内,安装臂的一端与缸体连接,安装臂的另一端连接电池包;电池包受到冲撞,缸体往电池包方向移动,缸体与安装臂之间将产生压缩封闭气腔的相对运动。上述技术方案在门槛梁上设置了连接装置,通过连接装置来缓冲整车受到的冲撞力,从而防止力传送到电池包,避免电池包受到损坏。
