The invention discloses a buffer energy-absorbing bumper, comprising a shell and a bumper collision rod which is erected at the front side of the shell through a plurality of energy-absorbing mechanisms. Each energy-absorbing mechanism comprises a first longitudinal energy-absorbing spring, two horizontal energy-absorbing springs, two fixed baffles, two sliding blocks and two dowel bars, wherein the front end of the first longitudinal energy-absorbing spring is connected with the bumper collision rod, and the rear end of the first longitudinal energy-absorbing spring is connected with the rear end of the shell; the two horizontal energy-absorbing springs are arranged at the rear end of the shell and are respectively positioned at two sides of the first longitudinal energy-absorbing spring; the two fixed baffles are arranged at the rear end of the shell and are respectively connected with one ends, far away from the first longitudinal energy-absorbing spring, of the two horizontal energy-absorbing springs; the two sliding blocks are arranged at the rear end of the shell and are respectively connected with the other ends of the two horizontal energy-absorbing springs; and the rear ends of the two dowel bars are respectively articulated with the two sliding blocks, and the front ends of the two dowel bars are articulated to the bumper collision rod. According to the invention, the collision force is decomposed by the longitudinal energy-absorbing springs and the horizontal energy-absorbing springs so as to realize shock absorption and energy absorption, thereby improving the safety performance of the bumper.
