Bottom support device for a battery box of a new energy automobile

Abstract

The invention relates to the technical field of battery articles and discloses a bottom support device for a battery box of a new energy vehicle, comprising a bottom plate, a side surface of the bottom plate is fixedly connected with a support plate, the number of the support plates is two, the support plates are symmetrically distributed on two sides of the bottom plate, the inner walls of the two support plates are movably connected with a support block, and a positioning plate is fixedly installed on the top of the support block. Through the action of the base plate, so that the bottom support of the battery box is more stable, components are prevented from affecting use of the bottom support when the bottom support is hit. By using the function of the supporting plate, the heat flow inside the battery box is discharged out of the battery box through the ventilation hole, the overheat inside the battery box is prevented, the service life of the battery is reduced, the safety of thebattery in use is improved, the function of the supporting block is used for cushioning the battery, and the battery is prevented from being collided.

Description

technical field [0001] The invention relates to the technical field of battery supplies, in particular to a bottom support device for a battery box of a new energy vehicle. Background technique [0002] The battery box is a group of batteries composed of several single batteries, box body, battery management system and related installation structural parts, etc., with standard battery box structure, battery box monitoring equipment, battery box connectors, battery box environmental control equipment Wait. [0003] The invention with the existing application number CN201710943203.8 discloses a special bottom support device for the battery box of a new energy vehicle. , the insulating layer provided has the function of high temperature resistance and fire prevention, and also has excellent buffer performance, which can play a buffer role for the battery box. In the present invention, the cooling fin includes a body, and the body has bosses and grooves connected at intervals. ...

AI Technical Summary

Problems solved by technology

[0009] Aiming at the deficiencies of the prior art, the present invention provides a bottom support device for a battery box of a new energy vehicle, which has the advantages of cushioning, good protection effect, dustproof, etc., and solves most of the bottom support of the battery box. During use, the bottom If the bracket is too hard, when the car encounters uneven roads, the battery will easily shake inside the battery box due to bumps, which will affect the life of the battery. At the same time, dust will easily enter the interior of the battery box through the gaps.
