Explosion-proof and fire-proof new energy automobile lithium battery

Abstract

The invention discloses an explosion-proof and fireproof new energy automobile lithium battery which comprises a mounting cavity and a supporting cavity fixedly connected with the mounting cavity, a lithium battery is mounted at the upper end of the supporting cavity, clamping parts are mounted at the two ends of the mounting cavity respectively, and each clamping part comprises a placement cavity, a rotating shaft, a gear, a rack plate, an extrusion plate and a clamping plate. Through grooves are formed in the side walls of the two ends of the mounting cavity correspondingly, the containing cavity fixedly communicates with one sides of the through grooves, the rack plate transversely penetrates through the containing cavity, the extrusion plate is fixedly connected to one end of the rack plate, the rotating shaft transversely penetrates through the containing cavity, the gear is fixedly connected to the rotating shaft, and the gear is fixedly connected to the gear. According to the lithium battery mounting device, when a lithium battery is placed in the mounting cavity, a second spring can play a role in buffering the lithium battery, and the situation that the lithium battery is damaged when the lithium battery is put down and collides with the side wall of the mounting cavity is avoided.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to an explosion-proof and fireproof new energy vehicle lithium battery. Background technique [0002] After more than 20 years of application and development, and the large-scale use of new energy vehicles in recent years, lithium-ion batteries have become mature in technology and comprehensive in industrial support, pushing the cost of new energy vehicles to approach fuel vehicles, thus becoming the mainstream of new energy vehicles. Power selection, as the most critical core component of new energy vehicles, lithium-ion power batteries directly affect the performance of new energy vehicles, including the cruising range, safety, service life, charging time and high and low temperature adaptability of new energy vehicles. [0003] The safety of lithium batteries for new energy vehicles has always been questioned by people. After all, cases of overheating and explosions eme...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the following shortcomings in the prior art. When the existing lithium battery is installed, it often collides with the side wall of the installation box, causing the battery shell to be easily damaged and destroying the internal structure of the battery. At the same time, most of them use screws after installation. Fixing the battery makes it inconvenient to install and disassemble the battery, and proposes an explosion-proof and fire-proof lithium battery for new energy vehicles
