Explosion-proof falling-off structure of battery pack of electric automobile

Abstract

The invention discloses an explosion-proof falling-off structure of a battery pack of an electric automobile. A battery box is clamped in a chassis; the bottom of the battery box is sealed by two bottom plates; batteries are arranged on the two bottom plates; a locking mechanism is arranged between the two bottom plates; when the temperature in the battery box is greater than T, the locking mechanism is unlocked; the two bottom plates are opened; the batteries are separated from the corresponding battery boxes; flammable and combustible gas released by the battery can be exhausted in time through a negative pressure pumping mechanism, so that precious buffer time is provided for a driver; and when the temperature of one battery is continuously increased to be possibly spontaneously combusted, the battery can be separated from an automobile through the unlocking of the locking mechanism, so that the safety of the automobile is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric vehicle batteries, in particular to an explosion-proof and falling-off structure of an electric vehicle battery pack. Background technique [0002] In recent years, with the transformation of automobile technology and in response to the country's call for energy conservation and environmental protection, new energy vehicles have emerged as the times require, which has promoted the rapid development of new energy vehicle technology. Among them, electric vehicles are powered by on-board power supplies. Compared with gasoline vehicles, they have less impact on the environment and can replace non-renewable gasoline resources. Their development prospects are widely optimistic. [0003] But at present, many technologies of electric vehicles are still immature, especially batteries, because batteries have certain requirements on temperature when they are working. Serious potential safety hazards. In re...

Problems solved by technology

[0003] But at present, many technologies of electric vehicles are still immature, especially batteries, because batteries have certain requirements on temperature when they are working. Serious potential safety hazards. In recent years, there have been too many car safety accidents caused by battery spontaneous combustion, which has seriously affected people's recognition of electric vehicles.
