AI Technical Summary

Technical Problem

The existing soft-pack lithium-ion battery module frame can only be used in one type of extreme ear connection method, which is difficult to meet different extreme ear connection requirements, and it takes time and effort to replace the extreme ear connection block.

Method used

A soft-pack lithium-ion battery module frame including a rotating fixing mechanism and a clamping mechanism is designed. The rotating fixing mechanism realizes rapid replacement and fixation of the electrode connecting block through the rotation of the T-shaped groove and the connecting plate; the clamping mechanism further fixes the electrode connecting block through the cooperation of the slide groove and the guide rod.

Benefits of technology

This design makes the replacement process of the ear connecting block more convenient and quick, and does not damage the ear fixing block, reducing the replacement cost and time.

Abstract

The utility model relates to the technical field of battery frames, and discloses a soft package lithium ion battery module frame which comprises a rectangular frame, a threaded through hole is formed in the front surface of the rectangular frame, and a rotary fixing mechanism is arranged on the front surface of the rectangular frame close to the top. By rotating the fixing mechanism, the tab connecting block slides into the T-shaped groove, then the connecting plate is rotated, the rotation of the connecting plate enables the connecting rod to rotate, so that the fixing block is rotated, the back surface of the fixing block is tightly attached to the front surface of the tab connecting block, and after the rotation of the connecting plate is completed, the second connecting hole coincides with the threaded hole; and then a bolt is inserted into a second connecting hole, then the bolt is rotated, so that the bolt rotates in a threaded hole, the bolt fixes the connecting plate, the connecting rod cannot rotate in the first connecting hole, the fixing block is fixed, the tab connecting block is convenient to replace in the process, and the tab fixing block cannot be damaged.
