The invention provides an energy absorption and shock absorption bumper and relates to bumpers. The energy absorption and shock absorption bumper comprises an automotive chassis frame (1), bolt and nut assemblies (2) and a safety baffle (3), the automotive chassis frame are fixedly connected with the two sides of the safety baffle through the bolt and nut assemblies, the safety baffle is in the U shape, taper holes (4) in n columns and m rows are formed in the two sides of the U-shaped safety baffle respectively, each taper hole is of the structure that the big hole diameter D and the small hole diameter d decrease in sequence, and the bolt and nut assemblies penetrate through big holes of the taper holes respectively and are fixedly connected with the automotive chassis frame to form a whole. The taper holes are formed in the two sides of the U-shaped safety baffle, when an automobile collides accidently, the bolt and nut assemblies (2) fixed at the big ends of the taper holes (4) are subjected to extrusion resistance of narrower and narrower space after the safety baffle (3) is impacted by impact force F, a buffer protection function is achieved, and safety of the automobile body, the driver and passengers is guaranteed.
