Battery box, battery pack and electric device

Abstract

This utility model discloses a battery box, a battery pack, and an electrical device. The battery box includes a main body and an arched support structure. The main body defines a first receiving cavity and a second receiving cavity. The first receiving cavity is suitable for accommodating individual battery cells. The arched support structure is disposed in the second receiving cavity and protrudes in a direction away from the first receiving cavity. In this embodiment of the battery box, by providing an arched support structure protruding in a direction away from the first receiving cavity, the arched support structure can absorb and buffer the external compressive force when the battery box is subjected to it. This helps to prevent deformation of the battery box to a certain extent, ensuring the structural integrity and stability of the battery box, thereby guaranteeing the performance of the battery box. This facilitates the protection of individual battery cells by the battery box, extending their service life. Furthermore, the arched support structure can cover the entire area of ​​the second receiving cavity, increasing the strength of the second receiving cavity and thus enhancing the strength of the battery box.
