The invention relates to a multi-cell-thin-wall energy absorbing structure and an application structure thereof. The multi-cell-thin-wall energy absorbing structure comprises an outer layer thin-wall energy absorbing structure and an inner layer thin-wall energy absorbing structure. The center line of a hollow small regular prism arranged in the inner layer thin-wall energy absorbing structure in a sleeved mode and the center line of a hollow large regular prism arranged in the inner layer thin-wall energy absorbing structure in a sleeved mode coincide with each other; a first connection rib plate and a second connection rib plate are connected between the middle positions of corresponding edges of the small regular prism and the large regular prism and corresponding corners. Two steel plates of the outer layer thin-wall energy absorbing structure are parallel to two edges of the corresponding edge corner of the inner layer thin-wall energy absorbing structure, and the included angle between the steel plates is the same as the degree number of the corresponding edge corners; one end of a third connection rib plate is connected with the two steel plates, the other end of the third connection rib plate is connected to the outside of the edge of the large regular prism; one end of a fourth connection rib plate is connected to the included angle of the steel plates, and the other end of the fourth rib plate is connected to the outer side of the edge corner of the large regular prism. The multi-cell-thin-wall energy absorbing structure can coordinate the conflict among high specific energy absorption SEA, high crush force efficiency CFE and good deformation modes of the energy absorbing structure, and the overall structure has good collision safety.
