The invention discloses an automobile vibration damping bumper, which comprises a bumper, a vibration damping mechanism, a buffer mechanism and a supporting mechanism. The two sides of the bumper main body of the bumper are sequentially provided with vibration damping rubber plates and auxiliary bumpers; the vibration damping mechanism It includes the first shock absorber, the second shock absorber, the guide rail frame and the buffer block. The two ends of the first shock absorber are respectively fixed on the auxiliary bumper and the buffer block by installing balls; the first buffer spring of the buffer mechanism, the connection The pad, the second buffer spring and the adjusting nut are sequentially connected and sleeved on the main body of the shock absorber, and the collision block is fixed at one end of the main body of the shock absorber; one end of the hydraulic cylinder of the supporting mechanism is hoisted in the guide tube through the fixed block, and the other end The supporting feet are connected by pin shafts. The arrangement of the bumper, the damping mechanism and the buffer mechanism of the present invention, when the vehicle collides from the front or oblique direction, multi-stage vibration damping, releases the supporting mechanism at the same time, increases the grip force and further improves the impact absorption performance of the bumper.
