Abstract

The present disclosure provides a buffering member and a battery module, the buffering member comprises a first member and a second member. The first member comprises a first main body and a first connecting portion, the second member comprises a second main body and a second connecting portion. The first main body and the second main body face each other, and the first connecting portion is cooperated with and fixedly connected to the second connecting portion. Because the first member and the second member are independent members, and they can be formed by separately cutting a sheet. Because the first member and the second member each are small in size and simple in structure, and they can be rapidly formed by using less material, the whole structure of the buffering member is simple and the buffering member uses less material, thereby maximally improving the utilization rate of the sheet.

First claim

What is claimed is:

1. A battery module, comprising a plurality of batteries and a plurality of buffering members, the plurality of batteries being arranged side by side in a third direction of the battery module, and each buffering member wholly being provided between a respective pair of two adjacent batteries in the third direction, wherein
each buffering member comprises a first member and a second member;
the first member comprises a first main body and a first connecting portion;
the second member comprises a second main body and a second connecting portion;
the first main body of the first member forms a first opening at the first connecting portion, and the second main body of the second member forms a second opening at the second connecting portion, the first opening and the second opening face each other in a plane which is positioned between a corresponding pair of adjacent batteries, and the first connecting portion is cooperated with and fixedly connected to the second connecting portion, so that the first member and the second member are spliced together in the plane and form a hollow frame structure.

2. The battery module according to claim 1 , wherein
the first connecting portion protrudes from the first main body in a second direction;
the second connecting portion protrudes from the second main body in the second direction;
the first connecting portion and the second connecting portion face each other in the third direction and are fixedly connected to each other.

3. The battery module according to claim 2 , wherein
the first connecting portion abuts against the second main body in the second direction and is fixedly connected to the second main body;
the second connecting portion abuts against the first main body in the second direction and is fixedly connected to the first main body.

4. The battery module according to claim 2 , wherein
a width of the first connecting portion in a first direction is equal to a width of the first main body in the first direction;
a width of the second connecting portion in the first direction is equal to a width of the second main body in the first direction.

5. The battery module according to claim 1 , wherein
the first connecting portion protrudes from the first main body in a second direction;
the second connecting portion is recessed from a surface of the second main body facing the first main body in the second direction;
the first connecting portion is received in the second connecting portion and fixedly connected to the second connecting portion.

6. The battery module according to claim 5 , wherein the second main body abuts against the first main body in the second direction and is fixedly connected to the first main body.

7. The battery module according to claim 5 , wherein
projections of the first connecting portion and the second connecting portion in the third direction each are semicircular; or
projections of the first connecting portion and the second connecting portion in the third direction each are triangular; or
projections of the first connecting portion and the second connecting portion in the third direction each are trapezoidal.

8. The battery module according to claim 5 , wherein
the first member further comprises a third connecting portion, and the third connecting portion is recessed from a surface of the first main body facing the second main body in the second direction;
the second member further comprises a fourth connecting portion, and the fourth connecting portion protrudes from the second main body in the second direction;
the fourth connecting portion is received in the third connecting portion and fixedly connected to the third connecting portion.

9. The battery module according to claim 1 , wherein
the first main body and the second main body each are formed as a C-shaped structure; or
the first main body and the second main body each are formed as a L-shaped structure.
