AI Technical Summary

Technical Problem

The sealing structure between the pole column and the cover plate of the traditional battery causes the electrolyte to accumulate and not flow easily, causing chemical reactions between the electrolyte and the pole column to come into contact with each other for a long time, affecting the performance of the pole column.

Method used

A structural member is designed, arranged in a chamber formed between the pole column and the cover plate, and a flow channel is provided in the structural member for flowing the electrolyte to avoid accumulation of electrolyte.

Benefits of technology

The electrolyte is freely circulated between the pole and the battery through the flow channel in the structural member, preventing the electrolyte from accumulating on the surface of the pole and extending the service life of the pole.

Abstract

The utility model discloses a structural member, a battery cover plate assembly, a battery device and electric equipment, the structural member is applied to a battery, the battery comprises a cover plate and a pole, the pole is connected to the cover plate, the structural member is suitable for being arranged in a first cavity, the first cavity is suitable for being formed by the pole and the cover plate, a flow channel is arranged in the structural member, the flow channel is communicated with the first cavity, and the flow channel is communicated with the cover plate. And the electrolyte can circulate. Therefore, when the structural member is used in the battery, the electrolyte can freely circulate in the pole and the battery through the flow channel in the structural member, so that the electrolyte is prevented from being accumulated on the surface of the pole to influence the performance of the pole.
