The invention discloses a multi-interlayer energy absorption buffering bumper with vertical pipes. The multi-interlayer energy absorption buffering bumper is characterized by comprising a front collision avoidance steel plate and a rear collision avoidance steel plate, wherein the front collision avoidance steel plate is located in front of the rear collision avoidance steel plate; the front collision avoidance steel plate and the rear collision avoidance steel plate are horizontally arranged; the opposite faces of the front collision avoidance steel plate and the rear collision avoidance steel plate are vertical surfaces; at least one middle collision avoidance steel plate which is parallel with the front collision avoidance steel plate and the rear collision avoidance steel plate is arranged between the front collision avoidance steel plate and the rear collision avoidance steel plate; two ends of the front collision avoidance steel plate, the middle collision avoidance steel plate and the rear collision avoidance steel plate are connected into a whole by side plates; the steel plates are gradually thickened from the front collision avoidance steel plate to the rear collision avoidance steel plate; a reinforcing rib which is vertical to the rear collision avoidance steel plate is connected with the rear of the rear collision avoidance steel plate; and cylindrical vertical pipes which are horizontally arrayed and provided with vertical axes are arranged between adjacent collision avoidance steel plates. When collision happens, the front layer is easier to deform than the rear layer; the front collision avoidance steel plate deforms and extrudes the vertical pipes; in the process of each layer of deformation, impact energy can be buffered and absorbed; acting force and reactive force are reduced; and the damage to the vehicle of opposite side is reduced.
