• and
• wherein the first sliding rail extends along a first reference ellipse, and the second sliding rail extends along a second reference ellipse;
• when the door body blocks the opening, a part of the first sliding rail away from the box body is away from the pivoting side, a part of the second sliding rail away from the box body is closer to the pivoting side, so that 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;
• and the opening comprises two opposite sides, the pivoting side is disposed on one of the two opposite sides, and the target side is disposed on the other of the two opposite sides;
