The invention discloses a fire fighting truck rear bumper device with an obstacle crossing function, and belongs to the technical field of vehicle tail safety devices. The fire fighting truck comprises a chassis girder connecting cross beam fixed between the opposite sides of the ends, facing the tail of the truck, of a pair of longitudinally-parallel frame chassis girders, and the rear bumper device with the obstacle crossing function comprises a left cantilever connecting frame, a right cantilever connecting frame, a left cantilever, a right cantilever and a rear bumper. The device is characterized in that a left cantilever automatic locking and unlocking mechanism is arranged between the front end of the left cantilever connecting frame and the upper end of the left cantilever, and a right cantilever automatic locking and unlocking mechanism is arranged between the front end of the right cantilever connecting frame and the upper end of the right cantilever. The rear-end collision prevention device has the advantages that the rear-end collision prevention device has the safety protection functions of normally absorbing and buffering external impact force when rear-end collision is caused by rear vehicles and preventing a rear-end collision car from entering the bottom of the car; therefore, the rear bumper automatically crosses the obstacle, and rapid passing of the vehicle is prevented from being delayed.
