Abstract

The invention relates to the technical field of battery accessories, and discloses a power battery aluminum shell with damping function and high safety. The aluminum shell comprises a shell body and a top cover; the top cover is fixedly connected on the top of the shell body through a fixing bolt; a placing plate is fixedly connected at the bottom of the shell body; a placing groove is opened on the supper surface of the placing plate; a battery main body is placed in the placing groove; both sides of the battery main body are provided with clamping plates. The power battery aluminum shell with damping function and high safety is provided with a first retractable spring, a first retractable rod, a balance plate, a second retractable spring and a second retractable rod; during the vibration process of the battery main body, two sides of the battery main body can be buffered and damped by the first retractable spring and the first retractable rod installed on two sides of the battery main body; the top of the battery main body can be pressed and shaken by the second retractable spring and the second retractable rod installed on the top of the battery main body. Thus, the battery main body can be damped on each side; the damping is more thorough; and the service life of the battery main body is prolonged.

Description

technical field [0001] The invention relates to the technical field of battery spare parts, in particular to a high-safety power battery aluminum case with a shock-absorbing function. Background technique [0002] The power battery is the power source that provides the power source for the tool. It mostly refers to the battery that provides power for electric vehicles, electric trains, electric bicycles and golf carts. Most of the power batteries on the market are power lithium batteries, but most of the power lithium batteries lack protection. The lithium battery is exposed to the air, which is prone to corrosion, and at the same time affects the service life of the power lithium battery. Therefore, people set up a protective case for the power lithium battery to protect the lithium battery. However, when the lithium battery is repaired or replaced During the process, it is often necessary to disassemble the lithium battery. If it falls on the ground during the disassembly ...
