Abstract

A casing includes a body for accommodating a battery management system and a mounting member fixed on the body. The mounting member includes a first end and a second end at opposite locations. The first end is provided with an elastic member. The second end is provided with a clamping portion. The clamping portion is configured to be clamped to an assembly bracket. The elastic member is configured to generate a rebound force under limitation of the assembly bracket, so as to fix the mounting member at a location on the assembly bracket.

Claims (16)

1. A casing for a battery box, comprising:

a body configured to accommodate a battery management system; and

a mounting member fixed on the body;

wherein the mounting member comprises a first end and a second end at opposite locations, the first end is provided with an elastic member, the second end is provided with a clamping portion, the clamping portion is configured to be clamped to an assembly bracket, and the elastic member is configured to generate a rebound force under limitation of the assembly bracket, so as to fix the mounting member at a location on the assembly bracket, and wherein the elastic member comprises a connecting end and a free end, the connecting end is configured to be connected to the first end, the free end is bent toward the mounting member, the free end has a straight section, and a side of the straight section that is oriented away from the mounting member is configured to abut against the assembly bracket to generate the rebound force.

2. The casing according to claim 1 , wherein the first end is further provided with a limiting portion, and the limiting portion is configured to limit curvature of the elastic member.

3. The casing according to claim 2 , wherein a maximum distance L between a bent portion of the elastic member and the connecting end and a distance D between the free end and the limiting portion satisfy L=(3.5 to 4.5)*D.

4. The casing according to claim 1 , further comprising:

a limiting plate, wherein two opposite plate surfaces of the limiting plate are respectively fixed on the body and the mounting member, and at least part of the limiting plate is configured to abut against an inner wall of the assembly bracket to fix the casing at a location on the assembly bracket.

5. The casing according to claim 1 , wherein the mounting member has at least one notch along an extension direction of the mounting member.

6. A battery box, comprising:

an assembly bracket; and

the casing according to claim 1 , wherein the casing is mounted on the assembly bracket.

7. A battery, comprising:

a battery cell; and

the box according to claim 6 , wherein the box is configured to accommodate the battery cell.
