The invention belongs to the technical field of automobile body structure manufacturing and provides a grooved type collision energy absorbing box for surface nanotechnology treatment. The whole external surface of the collision energy absorbing box is treated by using a surface nanocrystallization technology; a plurality of rhombic grooves are prefabricated in each edge area to guarantee the stability of the structure of the energy absorbing box and realize a preset deformation mode; the number of the grooves prefabricated at each edge is determined according to actual situations; and the positions of the grooves cannot be at the top end or the bottom end of the energy absorbing box as required and are uniformly distributed in the edge areas. According to the grooved type collision energyabsorbing box for the surface nanotechnology treatment, the surface nanocrystallization technology and groove arrangement are simultaneously applied to the collision energy absorbing box to induce abuckling mode and a development path of the energy absorbing box; and therefore, the integral strength and energy absorbing effect of the energy absorbing box can be improved, and moreover, the compressing force efficiency can be reduced, and the destruction form can be preset.
