Abstract

The invention discloses a battery tray, a battery pack and an electric vehicle. The battery tray includes an annular frame and a plurality of lifting lugs. The frame has an accommodating cavity extending along the circumferential direction of the frame. The multiple lifting lugs extend along the circumferential direction of the frame. The directions are arranged at intervals, and each lifting lug is arranged on the peripheral wall of the frame, and a placement cavity is formed in each lifting lug, wherein a first foamed aluminum foam is respectively arranged in the placement cavity and the position corresponding to the lifting lug of the accommodation cavity. pieces. The overall weight of the battery tray according to the present invention is relatively small, and has better buffering and energy-absorbing effect.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a battery tray, a battery pack and an electric vehicle. Background technique [0002] The overall structure of the battery tray in the related art is usually cumbersome, which makes it inconvenient to assemble with the vehicle body, and the energy absorption effect of the battery tray is not good. When the battery tray is impacted by an external force, it is easy to transfer too much impact energy to the battery module. , thus causing damage to the battery module. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a battery tray, which has a better buffering and energy-absorbing effect. [0004] Another object of the present invention is to provide a battery pack including the above battery tray. [0005] Another object of the present in...
