Built-in lithium ion battery module of vehicle-mounted automobile data recorder

Abstract

The invention relates to the technical field of lithium ion batteries, in particular to a built-in lithium ion battery module of a vehicle-mounted automobile data recorder, which comprises a recorder shell, lithium battery modules, a storage cover, a fixing column, a limiting assembly, a contact plate and a first conical wheel, the storage cover is fixed on the outer side surface of the recorder shell, and a plurality of groups of lithium battery modules are arranged in an inner cavity of the storage cover; inner cavities of the storage cover, the fixed cover and the movable cover are communicated, rotating discs are arranged on the upper side and the lower side of the side edge of the lithium battery module at the lower end, contact plates are arranged on the left side and the right side of the inner cavity of the fixed cover, a T-shaped rod penetrates through the middle of the outer side of the fixed cover, and limiting assemblies penetrate through the side ends of fixed columns arranged at the two ends of the T-shaped rod. The limiting assembly abuts against the outer side face of the contact plate, independent movement and installation of the lithium battery module are conveniently controlled through rotation of the rotating disc, opening and closing of the contact plate are conveniently controlled through the limiting assembly, and the working duration and opportunity of the lithium battery module are conveniently controlled.

Description

technical field [0001] The invention relates to the technical field of lithium-ion batteries, in particular to a built-in lithium-ion battery module of a vehicle-mounted driving recorder. Background technique [0002] Electronic core technology is the science of using electronic components to design and manufacture a circuit with a specific function to solve practical problems based on the principles of electronics, such as the operation of a car recorder, and the existing car recorder is powered by the car itself. When the car is off, it needs to be powered by a lithium-ion battery module. [0003] Lithium-ion battery modules tend to bulge abnormally after repeated use for many times, which affects the use of the recorder, and the contact points of the lithium-ion battery module pins are easy to corrode, so that the lithium-ion battery module needs to reduce the contact with the air. When going out, the recorder needs to be started after the car is turned off. It is necess...

AI Technical Summary

Problems solved by technology

[0003] Lithium-ion battery module after repeated use for many times, the monomer is abnormally swollen and easy to bulge, which affects the use of the recorder, and the contact points of the pins of the lithium-ion battery module are easy Corrosion makes the lithium-ion battery module need to reduce the contact with the air. When going out, the recorder needs to be started after the car is turned off, and the lithium-ion battery module needs to be prepared. However, once the existing lithium-ion battery module starts to work, unless the battery module is removed, Otherwise, it is impossible to control the shutdown of the battery module, and at the same time, it is impossible to control the working timing and duration of the lithium-ion battery, which will cause unnecessary waste and affect the performance of the recorder
