The invention provides a bumper structure for a car. A plurality of buffering units are distributed in an interval formed between an outer frame and an inner frame. Each buffering unit comprises a rectangular space and two plastic plates, wherein the rectangular space is defined by four aluminum alloy thin plates, and the two plastic plates are arranged at the two ends of the rectangular space and seal the rectangular space. Every two corresponding plastic plates are connected through a plurality of steel wire meshes, and each plastic plate internally comprises a plurality of springs; and each rectangular space is filled with buffering balls of different diameters. According to the bumper structure, when the buffering units are struck, the spaces in the buffering units can absorb certain impact force firstly till the spaces are broken, and the springs are contained in the plastic plates so that when being extruded, the plastic plates can be well buffered; when the sealed rectangular spaces are broken, the imp
