Lithium battery protection device based on snap-in limit structure

Abstract

The present invention relates to the technical field of lithium batteries, in particular to a lithium battery protection device based on a snap-on limit structure. It includes a lithium battery body and a limit protection mechanism on the outside of the lithium battery body. The limit protection mechanism at least includes: a protective shell, and a plurality of groups of moving grooves are arranged at the bottom of the inner cavity of the protective shell at equal intervals. The screw, the two side walls of the protective shell near the end are provided with support plates, and the fixing device includes a moving plate. The surface of the moving plate near the bottom is provided with a wire hole, and the wire hole is threadedly connected with the outer wall of the moving screw. The end of the inner surface of the plate is provided with a fixed arc plate, which is clamped to a limit device. The clamped limit device includes a support arc plate. The outer wall of the support arc plate is provided with two symmetrical placement plates. The placement plate is located on the top of the support plate, and the support arc plate Both ends are provided with limit card plates, the invention can limit and clamp the lithium battery inside the protective shell, and can combine a plurality of protective shells, so the practicability is stronger.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular, to a lithium battery protection device based on a clamping and limiting structure. Background technique [0002] A lithium battery is a battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution, so this battery is also called a lithium metal battery. Different from other batteries, lithium batteries have the characteristics of high charging density, long life and high unit cost; the interior of lithium batteries is very fragile, and it is easy to be damaged when being collided and squeezed, so it is necessary to use a protective device to protect the lithium battery body; [0003] However, the current lithium battery protection device cannot effectively fix the lithium battery body, causing the lithium battery to shake and be damaged in the protective case, and the current protection device is inconveni...

Problems solved by technology

[0003] However, the current lithium battery protection device cannot effectively fix the lithium battery body, causing the lithium battery to shake and be damaged in the protective case, and the current protection device is inconvenient to combine multiple groups together, and it is not convenient to protect the lithium battery pack separately. In view of this, we propose a lithium battery protection device based on a snap-in limit structure
