The invention discloses a negative Poisson's ratio gradient structure energy absorption box, which comprises a front mounting plate and a rear mounting plate, an annular outer plate is arranged between the front mounting plate and the rear mounting plate, a negative Poisson's ratio core body is arranged in the annular outer plate, the negative Poisson's ratio core body comprises a plurality of transverse core plates and longitudinal core plates, the transverse core plates and the longitudinal core plates are mutually perpendicular, and the transverse core plates and the longitudinal core plates are mutually perpendicular. The transverse core plate and the longitudinal core plate are both perpendicular to the front mounting plate, a plurality of peanut holes are formed in the transverse core plate and the longitudinal core plate respectively, every two adjacent peanut holes are perpendicular to each other, the positions of the peanut holes in the connecting positions of the transverse core plate and the longitudinal core plate correspond to each other, and the porosity of the negative poisson ratio core body is sequentially reduced from front to back; the energy-absorbing plate has the advantages of being good in energy-absorbing effect, high in installation performance and convenient to manufacture.
