Abstract: An edge beam for a battery tray, a battery tray, a battery pack, and a vehicle are provided. The edge beam includes an edge beam body. The edge beam body defines a cavity. The edge beam body has a partition portion. The partition portion is located in the cavity. The partition portion is connected between a top wall and a bottom wall of the cavity to partition the cavity into multiple sub-cavities. The multiple sub-cavities are arranged in sequence in a width direction of the edge beam. In a direction from an upper end to a lower end of the edge beam, the partition portion inclines away from the placement groove.

Abstract: The present disclosure discloses an edge beam for a battery tray, a battery tray, a battery pack and a vehicle. The edge beam includes: an edge beam body. The edge beam body defines a cavity, and the edge beam body has a partition portion. The partition portion is located in the cavity, and the partition portion is connected between a top wall and a bottom wall of the cavity to divide the cavity into a first sub-cavity and a second sub-cavity. The first sub-cavity and the second sub-cavity are arranged in a first direction of the edge beam in sequence. The first sub-cavity has a cross-sectional area of S1, the second sub-cavity has a cross-sectional area of S2, and S1 and S2 meet the relation formula: 0.8
