The invention belongs to the field of alarm devices, and particularly relates to a new energy automobile lithium battery fire alarm device which comprises a bearing plate. A warning mechanism is arranged in the bearing plate, and the bearing plate is installed at the bottom end of the new energy automobile lithium battery pack through screws. The warning mechanism comprises a driving assembly, an auxiliary fire extinguishing assembly and an ejection alarm assembly, one end of the driving assembly is provided with the auxiliary fire extinguishing assembly, the auxiliary fire extinguishing assembly is used for inhibiting rapid spreading of fire of the automobile lithium battery, and the ejection alarm assembly is arranged at the bottom end of the auxiliary fire extinguishing assembly. The ejection alarm assembly is used for warning surrounding vehicles and pedestrians; through the structural design of the warning mechanism, the function of warning surrounding vehicles and pedestrians in time before the lithium battery of the new energy automobile deflagrates is achieved, and liquid carbon dioxide stored in the storage cavity can be released to restrain fire of the battery while warning is conducted; and time is won for evacuation of fire rescue crowds and escape of drivers and passengers.

    本发明属于报警装置领域,具体地说是一种新能源汽车锂电池火灾报警装置,包括承载板;所述承载板的内部设置有警示机构,所述承载板通过螺丝安装在新能源汽车锂电池组的底端;所述警示机构包括驱动组件、辅助灭火组件和弹射报警组件,所述驱动组件的一端设置有辅助灭火组件,所述辅助灭火组件用于抑制汽车锂电池的火势快速蔓延,所述弹射报警组件设置在辅助灭火组件的底端,且弹射报警组件用于警示周围车辆和行人;通过警示机构的结构设计,实现了在新能源汽车锂电池爆燃前及时地对周围车辆和行人进行警示的功能,在进行警示的同时还可以将储存腔中所存储的液态二氧化碳释放出来抑制电池的起火,为消防救援人群疏散和驾乘人员逃生争取时间。
