The invention discloses a multi-channel front anti-collision device which comprises a front anti-collision beam assembly, a vehicle frame cross beam assembly, a vehicle frame left longitudinal beam assembly, a vehicle frame right longitudinal beam assembly and a lower protection plate assembly. The left end of the vehicle frame cross beam assembly is welded to the vehicle frame left longitudinal beam assembly, the right end of the vehicle frame cross beam assembly is welded to the vehicle frame right longitudinal beam assembly, and the front anti-collision beam assembly is fixed to the vehicle frame left longitudinal beam and the vehicle frame right longitudinal beam through a plurality of bolts. The front end of the lower anti-collision plate assembly is in threaded connection with the front anti-collision beam through a bolt, the rear end of the lower anti-collision plate assembly is in threaded connection with the frame cross beam assembly through a bolt, and a front anti-collision beam system is formed. The invention provides a double-channel multi-stage buffer system comprising a front anti-collision beam assembly, a frame longitudinal beam and a front anti-collision beam assembly, a lower protection plate assembly and a frame cross beam, so that the effective energy absorption and collision force conduction of a vehicle are met.
