The utility model discloses an automatic fire extinguishing device for a new energy vehicle, which comprises a fire extinguishing cylinder, a fire detecting tube and an alarm bell. The fire extinguishing cylinder is connected with a container valve. The container valve is connected with a pressure gauge through a fire detecting tube, and the pressure gauge is connected with a pressure switch through a fire detecting tube. The fire detection tube is connected with the alarm bell. The pressure gauge, pressure switch and alarm bell are installed in the cab. The fire detection tube between the container valve and the pressure gauge is installed above the generator, engine, motor and power battery. When a generator, engine, motor or power battery is on fire, the fire detection tube above the ignition position softens and explodes, the pressure in the fire detection tube drops, the container valve opens, and the fire gas stored in the fire extinguishing cylinder enters the fire detection tube through the container valve, and sprays out from the rupture of the fire detection tube and extinguishes it. Fire, pressure gauge in the pressure drop, pressure switch on, alarm bell start alarm, remind drivers and passengers to start fire extinguishing device, leave the cab as soon as possible.

本技术涉及新能源汽车自动灭火领域。
技术介绍
随着我国经济持续快速发展,人民生活的水平不断提高,机动车保有量持续上升,截止2016年底,全国机动车保有量达到2.9亿辆,其中私家车达1.46亿辆,国务院《“十三五”节能减排综合工作方案》多次提及新能源汽车,到2020年节能环保、新能源装备、新能源汽车等绿色低碳产业总产值突破10万亿元,成为支柱产业,公共机构率先淘汰老旧车,率先采购使用节能和新能源汽车,中国汽车工业协会对外发布的数据显示,2016年新能源汽车生产51.7万辆,销售50.7万辆,英国、法国、荷兰等欧洲国家已经提出了停止销售燃油车计划,中国已启动研究传统燃油车的退出时间表。2016年,根据公开资料不完全统计,全球共发生35起(46辆)新能源汽车起火事故,其中:国外6起(合计6辆),国内29起(合计40辆),很明显国内是新能源汽车起火事故的重灾区。新能源汽车起火的原因有动力电池导致的自然、零部件故障、充电和浸水,其中动力电池故障为主要起火原因,新能源汽车起火问题不仅关系着人民的人身、财产安全,同时在一定程度上会影响新能源汽车的推广 ...
