The technical scheme for realizing the aim of the utility model is as follows:

the utility model provides a battery case for replacing electricity, which comprises a case, wherein one side surface of the case is provided with a convex part protruding outwards, a containing cavity is formed in the convex part, and a socket mounting opening is formed in the convex part.

Preferably, the width of the protruding part is adapted to the width of the side surface of the housing, on which the protruding part is provided.

Preferably, the shell is provided with a handle.

Preferably, the top surface and at least one side surface of the housing are provided with the handle.

Preferably, the top surface of the protruding portion is lower than the top surface of the housing, and the socket mounting opening is formed in the top surface of the protruding portion.

Preferably, the shell is formed by involution connection of a main shell and a side cover.

Preferably, the main housing and the side cover are fixedly connected by a screw or welding.

The utility model has the positive effects that: (1) According to the battery shell structure, through the optimized design, the convex part protruding outwards is arranged on the shell, the battery management module is arranged in the accommodating cavity, and the socket is arranged at the socket mounting opening of the convex part, so that the height dimension of the shell can be reduced, and the requirement of the height dimension in mounting can be met.

(2) In the battery case for battery replacement, the width of the protruding part is adapted to the width of the side surface of the shell, on which the protruding part is arranged, so that the inner space of the accommodating cavity can be increased, and the battery management module can be better adapted to installation.
