Columnar battery case and battery thereof

Abstract

The invention discloses a columnar battery case and a battery thereof. The battery case includes a case body, wherein the case body comprises an outer case body and an inner case body; a spring damper is fixedly mounted in a cavity between the outer case body and the inner case body, the front surface and the back surface of the outer case body are both inlaid with radiating fins, and the bottoms of both sides of the outer case body are welded with a mounting base, the inner front surface and the back surface of the inner case body are both inlaid with heat conducting sheets, limiting grooves are welded on both sides of the inner part of the inner case body, an bottom end in the case body is fixedly provided with a damping spring, the top of the damping spring is fixedly connected with a base, an end cover is hinged to the top of the case body, and the top end on one side of the case body is provided with a mechanical lock body locked with the end of the end cover. The columnar battery case has the advantages of simple and reasonable structure design, convenient operation, easy installation, good heat dissipation effect, strong shock absorption capacity, safety and stability, stability of battery use, wide range of application, and favorable promotion and popularization.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a columnar battery case and also designs a battery. Background technique [0002] The current society pays more and more attention to the issue of environmental protection and energy saving, and products with environmental protection and energy saving have become more and more important. As a green, energy-saving and emission-reducing means of transportation, electric vehicles have played an increasingly important role in public travel. The main source of power for electric vehicles is the storage battery. Most of the existing storage batteries for electric vehicles are cylindrical batteries, and the shells of the cylindrical batteries are all single to protect and fix the battery body. The heat dissipation capacity of the shell is poor, which affects the service life of the cylindrical battery. The shock resistance of the outer casing is not good, and if the batte...

Problems solved by technology

The main source of power for electric vehicles is the storage battery. Most of the existing storage batteries for electric vehicles are cylindrical batteries, and the shells of the cylindrical batteries are all single to protect and fix the battery body. The heat dissipation capacity of the shell is poor, which affects the service life of the cylindrical battery. The shock resistance of the outer shell is not good. If the battery car is running violently, it may wear out in a columnar battery, which is not conducive to widespread promotion and popularization.
