Abstract

The present application provides a box device. A hinge assembly of the box device is provided with a first sliding rail and a second sliding rail. The first sliding rail extends along a first reference ellipse, and the second sliding rail extends along a second reference ellipse. When a door body blocks an opening, the part of the first sliding rail that is away from the box and the part of the second sliding rail that is away from the box are both away from a pivoting side, and the door body moves towards a target side of the box body during a process from blocking the opening by the door body to opening the door body relative to the box body, to reduce the extent to which the door body exceeds an outer sidewall of the box body.
