The invention discloses an early warning device for a front danger prompt and belongs to the technical field of automobiles. The early warning device comprises a vehicle body, an electronic control unit, a stress sensor, solenoid valves, a moving body, an oil drain pipe, an inertial block and an alarm, wherein the stress sensor is arranged on a front cover of the vehicle body, one end of an oil supply pipe is communicated with an oil tank, the other end of the oil supply pipe is communicated with an engine, one end of the oil drain pipe is communicated with the oil tank, the other end of the oil drain pipe is arranged outside a vehicle, the moving body is arranged in the oil tank, and the inertial block is connected with the moving body through a push rod. According to the early warning device, the electronic control unit controls switches of the solenoid valves when monitoring collision at the front part of the vehicle through the stress sensor, fuel oil is drained out of the vehicle through rapid forwards moving of the moving body, vehicle explosion is prevented, and passing vehicles are warned through the alarm. The early warning device for the front danger prompt is reasonable in structure, simple to design and applicable to optimal design of a car crash explosion-protection system.
