The invention relates to an automobile protection device and is characterized in that two symmetrical push rods are connected with the rear of an anti-collision rack. The push rods are provided with a spring, the rears of the push rod turn back towards inside in parallel, the outer sides of the push rods are connected with beam connecting rods. A front and a rear support rods are movably connected via a terminal pin and form a support rack. The front support rod of the support rack is arranged between the beam connecting rod and the rear turning-back section of the push rod and the pin is through a sliding slot on the beam connecting rod to movably connect the support rack, the beam connecting rod and the rear turning-back section of the push rod. The rear support rod of the support rack is movably connected with the beam connecting rod. When the automobile is collided, the push rod moves backwards after being impacted by force and due to the buffer function of the spring, the collision force is reduced. Meanwhile, the backward movement of the push rod brings along the front and the rear support rod to come close till the ends touch the ground, when the impulse force is induced tothe ground, a counterforce is generated and the collision force is reduced. The invention is a safety protection device with a novel and simple structure.
