Frame body and battery module

Abstract

The invention provides a frame body and a battery module. The frame body comprises two side plates and two end plates, wherein the end plates are used for connecting the two side plates to form the frame body; at least one end plate consists of a first connecting plate and a second connecting plate; the first connecting plate and the second connecting plate of at least one end plate are respectively formed integrally with one corresponding side plate, are opposite, and are fixedly connected together. Therefore, the quantity of spare parts of the frame body is low, and the structural consistency of the frame body is ensured. When the frame body is applied in the battery module, multiple batteries are placed in the non-closed frame body during blocking, and then the opposite first and secondconnecting plates of the frame body are fixedly connected together, so that a blocking procedure of the battery module is reduced; mass production is facilitated; and the production efficiency is improved. In addition, due to the misclosure of the frame body prior to the blocking, requirements for the consistency of the batteries are reduced; and the blocking is facilitated.

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...

AI Technical Summary

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
