Lithium battery protection device

Abstract

The invention relates to the technical field of lithium batteries, and discloses a lithium battery protection device. The lithium battery protection device comprises a placement box, a ventilation opening is formed in the surface of the placement box, a bearing is fixedly connected to the left side of the placement box, a round rod is rotatably connected to the rear side of the bearing, a top cover is fixedly connected to the surface of the round rod, and an interlayer plate is fixedly connected to the interior of the placement box. According to the lithium battery protection device, when an electric vehicle moves, the battery bottom plate and the battery shake, and a buffer spring and a pressing column at the lower end of the battery bottom plate are driven to press downwards, so that under the action of the buffer spring, the battery moves on the battery bottom plate simultaneously due to inertia force, so that the battery is prevented from being collided under the action of the buffer springs during shaking, the anti-collision problem of the battery during movement is well controlled, the protection of the battery can be well improved, the service life of the battery is prolonged, and circuit disconnection caused by collision during use is reduced.

Description

Technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery protection device. Background technique [0002] Among modern transportation tools, the existence of trams is a very convenient and smaller transportation tool, and the existence of trams is a certain degree of dependence on the convenience of people's lives. Therefore, trams play a pivotal role in modern society. Trams are just as the name suggests. It is driven by batteries. There are many types of batteries and their lifespans. In particular, the production of lithium batteries has become the mainstream of electric cars. [0003] During the movement of the tram, the lithium battery is usually placed directly in the battery storage box, or fixed inside the battery storage box with screws. During the movement of the tram, especially in rural riding, the road is not very It is flat, causing the lithium battery to collide in the storage box. Due to the lack o...
