The invention provides a collision energy absorption box. The collision energy absorption box comprises an upper flange, a composite energy absorber and a lower flange which are sequentially arranged from top to bottom; the composite energy absorber comprises a mixed section corrugated pipe and three stages of honeycomb inner cores arranged in the mixed section corrugated pipe; the three stages of honeycomb inner cores are sequentially provided with a first-stage honeycomb inner core, a second-stage honeycomb inner core and a third-stage honeycomb inner core from top to bottom; the first-stage honeycomb inner core, the second-stage honeycomb inner core and the third-stage honeycomb inner core are coaxially arranged; the first-stage honeycomb inner core and the second-stage honeycomb inner core are respectively formed by splicing honeycomb units; each honeycomb unit comprises a plurality of paper folding units from top to bottom, and the paper folding units are sequentially overlapped from top to bottom to form the honeycomb units; each honeycomb unit is provided with six side parts, and the honeycomb units are spliced through overlapping of the side parts. According to the technical scheme, the collision energy absorption box is simple in structure and can adapt to multi-angle impact.
