Frame and battery module

Abstract

The invention provides a frame body and a battery module. The frame body includes: two side plates; and two end plates, each end plate is used to connect the two side plates to form the frame body. At least one end plate is composed of a first connecting plate and a second connecting plate, the first connecting plate and the second connecting plate of the at least one end plate are respectively integrally formed with a corresponding side plate, and the at least one end plate The first connecting plate is opposite to the second connecting plate and is used for fixedly connecting together. Therefore, the number of parts of the frame is small and the structural consistency of the frame is guaranteed. When it is applied to a battery module, a plurality of batteries are first placed in an unclosed frame when forming a group, and then the The opposite first connecting plate and the second connecting plate of the frame body need only be fixedly connected together, thereby reducing the assembly process of the battery modules, facilitating mass production and improving production efficiency. At the same time, due to the non-closed nature of the frame before being grouped, the consistency requirements for multiple batteries are reduced, which is convenient for grouping.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a frame body and a battery module. Background technique [0002] A battery module generally includes a plurality of batteries and a frame for accommodating and clamping the plurality of batteries, and the frame is formed by fixedly connecting two end plates and two side plates. At present, in actual production, there are two ways to form the frame body: (1) The two end plates and two side plates of the frame body of the battery module are usually welded by tailor welding, that is, the In the grouping process, the relative positions of each end plate, multiple batteries and each side plate are generally set first, and then each end plate and the corresponding side plate are tailor-welded to form accommodating and clamping multiple The frame of the battery; (2) The two end plates and the two side plates of the frame are integrally formed to form an integral structure, that is, in the proc...

Problems solved by technology

[0003] For the tailor-welded frame, due to the large number of parts (4), it is difficult to ensure the structural consistency of the frame during tailor-welding, and it increases the battery module during the grouping process. Group process, resulting in low production efficiency

For the integrally formed frame, although the structural consistency is high and the grouping process is reduced, in the grouping process of battery modules, it is difficult or even impossible to group multiple batteries with large size differences. Complete the grouping, so the one-piece frame has high requirements for the consistency of multiple batteries in the battery module
