1. A drawer assembly, comprising a drawer body and a slideway assembly on which the drawer body is pushed and pulled, wherein the drawer assembly further comprises a damping reset unit matching the drawer body and being arranged on the slideway assembly, and wherein the damping reset unit comprises an elastic member that drives the drawer body to reset from an open state to a closed state, and a damping member that reduces the reset speed of the elastic member;
wherein the damping member has a housing fixed relative to the slideway assembly and a piston rod that is telescopic relative to the housing along a push-pull direction of the drawer body and generates damping with the housing when it telescopes, and a deformation direction of the elastic member is consistent with the push-pull direction of the drawer body;
wherein one end of the elastic member is fixed on the housing, the other end is fixed on the piston rod, and the elastic member has a minimum stretch when the drawer body is in a closed state;
wherein the piston rod is provided with a retaining portion protruding toward the drawer body, the drawer body is provided with a linkage which is fitted with the retaining portion so that the piston rod extends relative to the housing as the drawer body is opened, and the elastic member generates a return force for returning the drawing body when the piston rod is in an extended state;
wherein the damping member has a locking structure that keeps the drawer body in the open state.
