AbstractThe collision-prevention device for car is characterized by that the collision energy is used to change oil pressure flow capacity and control pressure, and pressure storage device is used to absorb part of collision energy so as to convert the collision energy and do not make car body absorb said collision energy. Said invented collision-prevention device mainly includes: an impaction mechanism formed from collision-prevention bar parallelly-mounted on the oil cylinder; a motor pump connected between the oil cylinder and oil storage tank and providing pressure source for impaction mechanism to make it extend out or draw back; a pressure pipeline connected between oil cylinder, oil storage tank and motor pump; and a buffer pipeline providing pressure for bubering impact. Said invention can form several loops and can obtain optimum collision-prevention effect.
