Lithium-sulfur battery pack with buffering function

Abstract

The invention discloses a lithium-sulfur battery pack with a buffering function. The lithium-sulfur battery pack comprises a battery pack shell, wherein a sleeve is fixedly arranged at the bottom of an inner cavity of the battery pack shell; a supporting rod is connected into an inner cavity of the sleeve in a sliding manner; the bottom of the supporting rod is fixedly connected with the bottom of a piston; and the top of the supporting rod penetrates out of the sleeve and is movably connected with the bottom of a movable plate. According to the battery pack, due to the matched battery pack shell, sleeve, supporting rod and piston, the movable plate can move up and down; due to the arrangement of a guide pipe, an inflatable cushion and a compression spring, the movable plate has an effect of buffering external force while moving up and down; by matching a spring, a movable rod, a sliding cover and a fixed cylinder, the lithium-sulfur battery pack in a liner is protected and prevented from being damaged due to swinging, the impact caused by external up-and-down swinging on the battery pack in the liner is reduced; and impact from a side face of the shell of the battery pack is buffered due to the arrangement of the cushion, so that the buffering effect of the lithium-sulfur battery pack is achieved.

Description

technical field [0001] The invention relates to the field of battery technology, in particular to a lithium-sulfur battery pack with a buffer function. Background technique [0002] Lithium-sulfur battery is a kind of lithium battery. It uses sulfur as the positive electrode of the battery and metal lithium as the negative electrode. In order to make the battery provide more powerful current, people connect multiple batteries in series to form a battery pack, but At present, the lithium-sulfur battery packs on the market are prone to battery damage after external impacts due to poor buffering function, resulting in an open circuit in the battery pack and making the battery pack unable to provide power. . Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a lithium-sulfur battery pack with a buffer function, which solves the problem that the existing lithium-sulfur battery pack mentioned in the background art suff...
