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 so as to separate the cavity into a first sub-cavity and a second sub-cavity, and the first sub-cavity and the second sub-cavity are communicated with each other; the first sub-cavity and the second sub-cavity are sequentially arranged in the first direction of the boundary beam, the cross section area of the first sub-cavity is S1, the cross section area of the second sub-cavity is S2, and the relational expression that S1/S2 is larger than 0.8 and smaller than 1 is met. Therefore, by means of the boundary beam body, the structural strength and rigidity of the boundary beam can be improved, it can be guaranteed that the mode of the battery pack is appropriate, the collision force can be absorbed when the sub-cavities are collided, the magnitude of the collision force transmitted to the interior of the battery pack is reduced, 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.

    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第一子腔和第二子腔,第一子腔和第二子腔在边梁的第一方向依次排布,第一子腔的横截面面积为S1,第二子腔的横截面面积为S2,满足关系式:0.8<S1/S2<1。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,也能够保证电池包模态适宜,子腔受到撞击时能够吸收碰撞力,降低了传递至电池包内部碰撞力大小,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。
