AI Technical Summary

Technical Problem

After the high-power battery pack is filled with glue, the glue will fill between the battery cells and the cavity, increasing the weight of the battery pack, affecting the energy density, and possibly causing poor contact with precision devices.

Method used

A battery cell support is designed, with a plurality of protruding parts arranged on the bearing surface, and the protruding parts are arranged in an array on the bearing surface to form a housing space, and the gap between the battery cells is sealed through the protruding parts to prevent glue from entering.

Benefits of technology

It effectively reduces the overall weight of the battery pack, prevents glue from entering the gap around the battery cell or between the battery cells, and improves the structural stability of the battery cell bracket and the discharge performance of the battery pack.

Abstract

The embodiment of the utility model provides a battery cell bracket, a battery pack, a battery pack and electric equipment, and belongs to the technical field of battery manufacturing. The battery cell bracket is provided with a bearing surface, the bearing surface is convexly provided with a plurality of convex parts, the plurality of convex parts are arranged on the bearing surface in an array manner, at least two convex parts are mutually encircled to form accommodating spaces for accommodating battery cells, the convex parts are isolated and plugged between the at least two accommodating spaces, and cavities are formed in the convex parts. According to the battery pack provided by the embodiment of the invention, the lug bosses fill the mounting gaps around the battery cells or between the battery cells, so that glue is not easy to enter the mounting gaps around the battery cells or between the battery cells during glue pouring, and the overall weight of the battery pack is reduced. And meanwhile, the lug boss and the battery cell bracket are of an integrated structure, so that the structural strength is improved, the battery cell can be effectively limited and fixed, and structural damage caused by shaking and collision of the battery cell is avoided.
