The storage device according to claim 1 , wherein the automatic door-opening assembly further comprises: a plurality of elastic washers provided between the plurality of connecting protrusions and the plurality of through holes respectively; each said elastic washer comprising: two damping portions provided at the peripheral edge of the through hole close to the box body and the peripheral edge of the through hole close to the housing respectively; and a connecting portion provided in the through hole and connected with the two damping portions. 3 . The storage device according to claim 2 , wherein each said elastic washer further comprises: a plurality of spherical protrusions provided on the two damping portions respectively and protruding in a direction away from the connecting portion. 4 . The storage device according to claim 1 , wherein each said automatic door-opening device comprises: a motor configured to provide a driving force for opening the door body; and a side wall of the housing away from the box body is provided with at least one avoiding hole, and part of each said motor is provided in one said avoiding hole. 5 . The storage device according to claim 4 , wherein the automatic door-opening assembly further comprises: at least one sealing ring provided between the at least one avoiding hole and the at least one motor. 6 . The storage device according to claim 1 , wherein the box body comprises: an outer box, a liner and a heat insulation layer provided between the outer box and the liner; and a metal reinforcement provided between the outer box and the heat insulation layer, the housing being configured to be at least fixedly connected with the metal reinforcement. 7 . The storage device according to claim 6 , wherein the housing is configured to cover at least one hinge device connecting the box body and the at least one door body; and one of the metal reinforcement and the housing is provided with a plurality of positioning protrusions, the other of the metal reinforcement and the housing is provided with a plurality of annular protrusions, and the plurality of positioning protrusions are provided in inner rings of the plurality of annular protrusions respectively, so as to restrict the motion of the housing in the radial direction of the annular protrusions. 8 . A storage device, comprising: a box body and at least one door body; and an automatic door-opening assembly for opening the at least one door body, the automatic door-opening assembly comprising: a housing fixedly connected to the box body; and at least one automatic door-opening device, each said automatic door-opening device being at least partially provided on a side, close to the box body, of the housing, and fixedly connected to the housing, so as to fix the at least one automatic door-opening device; wherein the box body comprises: an outer box, a liner and a heat insulation layer provided between the outer box and the liner; and a metal reinforcement provided between the outer box and the heat insulation layer, the housing being configured to be at least fixedly connected with the metal reinforcement; wherein the housing is configured to cover at least one hinge device connecting the box body and the at least one door body; and wherein one of the metal reinforcement and the housing is provided with a plurality of positioning protrusions, the other of the metal reinforcement and the housing is provided with a plurality of annular protrusions, and the plurality of positioning protrusions are provided in inner rings of the plurality of annular protrusions respectively, so as to restrict the motion of the housing in the radial direction of the annular protrusions. 9 . The storage device according to claim 8 , wherein the automatic door-opening assembly further comprises: a plurality of fasteners configured to fixedly connect the at least one automatic door-opening device to the housing and to fixedly connect the housing to the box body; wherein the at least one automatic door-opening device is fixed to the housing by the fasteners in a direction away from the box body; wherein the housing is fixed to the box body by the fasteners in a direction towards the box body. 10 . The storage device according to claim 9 , wherein each said automatic door-opening device is provided with a plurality of through holes; and the housing is provided with a plurality of connecting protrusions extending towards the box body, and each said connecting protrusion is configured to penetrate through one said through hole, wherein the fasteners are configured to be fastened to the connecting protrusions. 11 .
