The invention discloses a battery tray, a battery pack and a vehicle, the battery tray comprises a frame and a bottom plate, the bottom plate is arranged at the bottom of the frame, the bottom plate and the frame cooperate to define a containing space, and a battery module is suitable for being placed in the containing space. A plurality of first containing grooves are formed in the bottom wall, deviating from the containing space, of the bottom plate; and the plurality of first containing grooves are respectively provided with the rotatable rotating parts, and one part of each rotating part is exposed out of the corresponding first containing groove. Therefore, by arranging the multiple rotating pieces, when the multiple rotating pieces of the bottom plate are impacted, the rotating pieces rotate in the first containing grooves, the stress direction of the bottom plate is changed for buffering and force unloading, the bottom plate can be prevented from being directly impacted by impact force, the deformation risk of the bottom plate is reduced, the bottom plate is effectively prevented from extruding the battery module, thermal runaway of the battery module is avoided, and the service life of the battery module is prolonged. And the use safety of the battery pack is improved.
本发明公开了一种电池托盘、电池包以及车辆,电池托盘包括:框架和底板,所述底板设在所述框架的底部,所述底板和所述框架配合限定出盛放空间,电池模组适于放置于所述盛放空间,所述底板的背离所述盛放空间的底壁设有多个第一盛放槽;多个转动件,多个所述第一盛放槽分别设有可转动的所述转动件,每个所述转动件的一部分外露于所述第一盛放槽。由此,通过设置多个转动件,当底板的多个转动件受到撞击时,转动件在第一盛放槽内转动,改变底板的受力方向进行缓冲卸力,可以避免撞击力直接撞击底板,降低底板变形风险,有效防止底板挤压电池模组,避免电池模组发生热失控,提升电池包的使用安全性。
