Hierarchical bumper structure

The utility model relates to a hierarchical bumper structure which comprises spaced front anticollision beam component and front longitudinal beam component, wherein two parallel steel plates are welded between the front anticollision beam component and the front longitudinal beam component, a welding seam between the two steel plates are segmented into a front part and a rear part to form a primary bumper and a secondary bumper. The hierarchical structure is adopted to separate the bumper into the primary bumper and the secondary bumper, and the application and protection ranges of the automobile bumper are increased. For passengers, the safety and the sense of security are increased. With the hierarchical bumper structure, pedestrians and automobiles can be best protected during low-speed collisions, and hospitalization for accidents and maintenance cost for automobile damages are lowered.
