The utility model discloses a kind of integrated battery support with fire extinguishing module, including integrated battery support, the fixed position of module positive and negative busbar is equipped on integrated battery support, several fire extinguishing holes, fire extinguishing module is installed in fire extinguishing hole;Fire extinguishing module includes fire extinguishing groove, fire extinguishing powder packet is equipped in fire extinguishing groove, the top cover of fire extinguishing groove is equipped with module upper cover, heat-sensitive wire is connected on fire extinguishing powder packet, the bottom of fire extinguishing groove is equipped with several gas injection holes.The utility model has the beneficial effect that: the fixed position of module positive and negative busbar is equipped, module structure is simplified and module cost is reduced, BMS module can be installed on module upper side;When cell thermal runaway, fire-extinguishing gas will be injected, and the temperature of thermal runaway is detected by heat-sensitive wire to automatically trigger fire extinguishing module to start, and the reaction is rapid.

This invention belongs to the field of mining vehicle technology and solves the problem of high fire risk in the engine compartment of mining vehicles in the prior art. This invention provides an automatic fire extinguishing system for mining vehicles, including a protective box and a fire extinguishing tank. The fire extinguishing tank is connected to a conduit, which is connected to a spray pipe. The spray pipe is equipped with a nozzle and a fire source detector. The protective box includes an outer box fixedly installed on the vehicle frame, and an inner box is set inside the outer box. The fire extinguishing tank is installed in the inner box. A primary vibration isolation component is set between the four inner side walls of the outer box and the four outer surfaces of the inner box. A gas injection component with an outlet aimed at the fire source detector is connected to the spray pipe. When the inner box shakes, the primary vibration isolation component absorbs the vibration force and pressurizes the gas injection component. When the gas pressure in the gas injection component reaches a threshold S, the gas injection component sprays high-pressure gas toward the fire source detector. This device can achieve automatic fire extinguishing of the engine compartment for a long time and effectively.
