Explosion venting device can be opened quickly when internal pressure of system abnormally rises, to release pressure, so as to prevent explosion accident of system, and ensure safe operation of system.

[0003] In related art, the explosion venting device includes an explosion venting plate, a housing, a plug-in part, and a transmission assembly. The transmission assembly includes a first connecting rod, a second connecting rod, a steering rod, etc. When the internal pressure of the energy storage device increases, the explosion venting plate will deform or displace, and the plug-in part will move out of the plug-in hole through the transmission assembly, thereby achieving explosion venting.
