The invention discloses an automobile collision buffer device, and relates to the technical field of automobiles. Each energy-absorbing cylinder is connected to a spring energy-absorbing cylinder in a clearance fit manner; the spring energy-absorbing cylinder is connected to a hydraulic cylinder sleeve; the energy-absorbing cylinder is disposed in an energy-absorbing beam sleeve in a sliding manner; a spring limit rod is arranged at the bottom end of the energy-absorbing beam sleeve; the ends of the spring limit rod penetrate the energy-absorbing cylinder; push springs are arranged on the portion, under the energy-absorbing cylinder, of the spring limit rod in a penetrating manner; the bottom end of the energy-absorbing cylinder is in plugging connection with bolts; the bolts cooperate with electromagnets; limit pin sleeves are arranged on the upper side wall of the energy-absorbing beam sleeve; each limit pin sleeve is internally provided with a limit pin; a pressure spring is cooperatively arranged between each limit pin and the wall of the corresponding limit pin sleeve; the spring energy-absorbing cylinder is internally provided with energy-absorbing springs which are fixed to a spring positioning disc; and a piston rod is disposed in the hydraulic cylinder sleeve in a penetrating manner. The automobile collision buffer device improves automobile collision energy-absorbing effects, protects an automobile and pedestrians, reduces the damage to the front structure of the automobile, is low is cost, and is high in practicality.
