Fire extinguishing system for driving part of new energy electric vehicle

Abstract

The invention discloses a fire extinguishing system for a driving part of a new energy electric vehicle. A driving assembly comprises a driving motor, a gearbox and an electronic power control assembly, the power output end of the driving motor is in transmission connection with wheels through the gearbox, and the electronic power control assembly is mounted on the driving motor. The fire extinguishing system also comprises a temperature, smoke and flame detection module, a controller and a dry powder fire extinguishing module, the temperature, smoke and flame detection module is arranged on the outer surface of the driving assembly, the dry powder fire extinguishing module and the temperature, smoke and flame detection module are both electrically connected with the controller, and a fire extinguishing agent spraying opening of the dry powder fire extinguishing module faces the peripheral side of the driving assembly. The fire extinguishing system for the driving part of the new energy electric vehicle has the technical effects that the fire extinguishing of a vehicle-mounted driving assembly is realized by detecting any one signal of temperature, smoke or flame, the safety of a driver and passengers is effectively ensured, and enough time is provided for people to escape when a fault occurs.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a fire extinguishing system for driving parts of new energy electric vehicles. Background technique [0002] In the prior art, electric vehicles and electric bicycles often have the possibility of spontaneous combustion or fire and explosion caused by thermal runaway of the battery during the use of their drive parts.
