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.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a battery pack installation structure of an electric automobile. Background technique [0002] The battery pack is the core component of the vehicle structure of the electric vehicle, providing the power source for the electric vehicle. The structural layout and installation of the battery pack are the key factors for the overall performance of the electric vehicle. The battery pack is generally arranged under the front floor of the vehicle body, and its weight accounts for the Cars are larger. In traditional electric vehicles, the overall connection strength between the battery pack and the body is insufficient. When the electric vehicle collides, the battery pack is easily damaged, and the safety of the electric vehicle is reduced. [0003] like figure 1 In the car sill beam structure shown, under the collision condition of the whole vehicle, the main body of the battery ...
