The invention discloses an edge beam for a battery tray, the battery tray, a battery pack and a vehicle, the edge beam comprises an edge beam body, the edge beam body defines a cavity, the edge beam body is provided with a separation part, the separation part is located in the cavity, the separation part is connected between the top wall and the bottom wall of the cavity to divide the cavity into a plurality of sub-cavities, and the sub-cavities are located in the cavity; the sub-cavities are sequentially arranged in the width direction of the edge beam, and the partition parts incline in the direction away from the containing grooves from the upper end to the lower end of the edge beam. Therefore, through the boundary beam body, the structural strength, rigidity and stability of the boundary beam can be improved, the deformation risk of the boundary beam can be reduced, and therefore the service life of the boundary beam and the service life of the battery tray can be prolonged, when the sub-cavities, away from the containing groove of the battery tray, in the multiple sub-cavities are collided, the collided sub-cavities can absorb collision force, and the collision force is reduced. And the impact force transmitted to the interior of the battery pack is reduced, so that the use safety of the battery pack can be improved.

    本发明公开了一种用于电池托盘的边梁、电池托盘、电池包以及车辆,边梁包括:边梁本体,边梁本体限定出空腔,边梁本体具有分隔部,分隔部位于空腔内,分隔部连接在空腔的顶壁和底壁之间以将空腔分隔为多个子腔,多个子腔在边梁的宽度方向依次排布,从边梁的上端至下端方向,分隔部朝向远离放置槽的方向倾斜。由此,通过本申请的边梁本体,能够提升边梁的结构强度、刚度以及稳定性,可以降低边梁变形风险,从而可以延长边梁、电池托盘的使用寿命,并且,多个子腔中远离电池托盘的放置槽的子腔受到撞击时,受到撞击的子腔能够吸收碰撞力,降低了传递至电池包内部碰撞力大小,从而可以提升电池包使用安全性。
