Abstract

The invention provides an automatic fire extinguishing system of an electric automobile. The automatic fire extinguishing system comprises a plurality of flame detectors, a ventilation door, an electrical control unit, a fire-extinguishing gas generator and an igniter, wherein the flame detectors are arranged in the power battery accommodating position of the electric automobile, the ventilation door is arranged in the power battery accommodating position, and the igniter is used for igniting fire-extinguishing gas generator; an outlet of the fire-extinguishing gas generator is connected with confined space; the flame detectors transmit detection signals to the electrical control unit; and the electrical control unit controls the igniter and the ventilation door. The fire extinguishing system is safe and reasonable in arrangement.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to an electric vehicle fire extinguishing system. Background technique [0002] Recently, there have been frequent fire accidents of electric vehicles in China. Now the whole people are talking about "electricity". At present, due to short circuit, overcharging and other reasons, electric vehicles cause fire and combustion. Most electric vehicle fires start from the battery and then spread to other parts. Existing electric vehicle fire extinguishers are not only inconvenient to arrange, but also the gas and powder ejected during fire extinguishing are not conducive to human health, so a safe and reasonably arranged fire extinguishing system is urgently needed. Contents of the invention [0003] In order to solve the above problems, the patent of the present invention provides a fire extinguishing system for automatically extinguishing the initial fire. [0004] In order to solve the above...
