Convenient-to-disassemble and assemble lithium battery pack

Abstract

The invention discloses a convenient-to-disassemble and assemble lithium battery pack, which comprises an internal sleeve, an external sleeve, a guide assembly and an adsorption assembly, wherein a hollow cavity structure is formed in the internal sleeve; an opening is formed in the upper part of the internal sleeve; openings are formed in the upper part and the lower part of the external sleeve; the external sleeve sleeves the outside of the internal sleeve, is connected with the internal sleeve through the guide assembly, and freely moves up and down along the internal sleeve; limiting grooves are formed in two side surfaces of the external sleeve; a baffle plate is inserted into each limiting groove; each baffle plate is inserted from the limiting groove at one side of the external sleeve, runs through the external sleeve and extends out of the limiting groove at the other side; the baffle plates are placed on the internal sleeve to prevent the external sleeve from sliding downwards; and the adsorption assembly is arranged at the bottom part of the internal sleeve, so that the internal sleeve is absorbed and fixed. The convenient-to-disassemble and assemble lithium battery pack is simple in structure and reasonable in structure; and the internal sleeve is connected with the external sleeve by the guide assembly, so that upper and lower positioning and fixing of a plurality of lithium batteries are achieved.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to a lithium battery pack which is easy to assemble and disassemble. Background technique [0002] Lithium-based batteries are divided into lithium batteries and lithium-ion batteries. Lithium-ion batteries are used in mobile phones and laptops, commonly known as lithium batteries. With the development of science and technology, lithium batteries have become the mainstream now. Batteries generally use lithium-containing materials as electrodes, which are representatives of modern high-performance batteries; lithium battery packs are the most commonly combined structural type of lithium batteries, and are widely used in notebook batteries, LED flashlights, digital cameras, miner's lamps, and medical equipment. , emergency lights and other manufacturers, can play a very good role in protecting electrical appliances, and the short circuit of lithium battery packs is a more serious pro...

Problems solved by technology

Batteries generally use lithium-containing materials as electrodes, which are representatives of modern high-performance batteries; lithium battery packs are the most commonly combined structural type of lithium batteries, and are widely used in notebook batteries, LED flashlights, digital cameras, miner's lamps, and medical equipment. , emergency lights and other manufacturers, can play a very good role in protecting electrical appliances, and the short circuit of lithium battery packs is a more serious problem. The existing lithium battery pack pole pieces are connected to the surface of conductive objects, which are easy to short circuit. A short circuit will cause heat generation and damage the battery, and a short circuit will generate a high current, which will cause the battery to heat up and the electrolyte will leak, producing toxic gases; in addition, the existing lithium battery pack has a single voltage and poor flexibility, and cannot adapt to the use of variable voltage requirements environment, in order to change the voltage, it is necessary to reassemble the entire lithium battery pack, which is complicated to operate and inconvenient to use
