1412, 1413, and the second opening 145 is disposed opposite to the first opening 144.

Further, the elastic structure 143 may be a tension spring, a rubber spring, or another elastic element.

In order to ensure that the first opening 144 is always aligned with the hinge axis, in an embodiment of the present invention, a limiting member is disposed in the second opening 145 between the first fastening member 1412 and the second fastening member 1413 to limit the moving distance between the first fastening member 1412 and the second fastening member 1413, so as to ensure that the opening of the first opening 144 is always aligned with the hinge axis 122.

In an embodiment of the present invention, the actuating mechanism 16 includes a link 162 disposed at the second opening in a matching manner, a cross-sectional area of one end of the link 162 is much larger than a cross-sectional area of the other end, and when the hinge shaft 122 moves from the accommodating space 142 to the outside of the first opening, the link 162 moves in the second opening to gradually reduce a cross-sectional area of a portion of the link in the second opening 145, and the opening size of the second opening 145 is gradually reduced under the action of the elastic structure 143.

In order to prevent the link 162 from being separated from the integrated device during the movement process to the outside of the first opening, in an embodiment of the present invention, the link 162 extends along the radial direction of the shaft sleeve 141 and is always inserted into the second opening 145.

In an embodiment of the present invention, the actuating mechanism 16 further includes an actuating member 164 connected to one end of the link member, and the actuating member 164 drives the link member 162 to move toward the inside of the accommodating space 142 when the hinge shaft moves from the accommodating space 142 to the outside of the first opening. And the actuator 164 has a limit to the moving distance to prevent the link 162 from being separated from the entire device.

In an embodiment of the present invention, the actuating member 164 is an elastic member connected to a side of the link member facing away from the hinge shaft 122 along a radial direction of the bushing. Optionally, the actuator 164 is a compression spring assembly.

In order to enable the link member 162 to move smoothly in the second opening and satisfy a condition that the cross-sectional area of one end is much larger than that of the other end, optionally, the link member 162 is a conical structure radially penetrating the second opening along the shaft sleeve. In an embodiment of the present invention, the link 162 is a taper pin, and the link 162 may have other embodiments, which are not described herein for illustration purposes.

Further, the large end of the link 162 is disposed toward the inner side of the accommodating space, and a fitting surface 1621 matched with the hinge shaft 122 is formed at the large end, and the fitting surface 1621 is a smooth curved surface matched with the outer circumferential surface of the hinge shaft.

Referring to fig. 3, the mating surface 1621 may be divided into a first contact surface 1622 and a second contact surface 1623. When the hinge shaft 122 is located in the accommodating space 142, the first contact surface is in close contact with the outer peripheral surface of the hinge shaft 122; when the hinge shaft 122 moves from the accommodating space 142 to the outside of the first opening 144, the hinge shaft 122 slides from the first contact surface 1622 to the second contact surface 1623, and when the hinge shaft 122 continues to move to the outside of the first opening 144, the link 162 continues to extend to the first opening 144 under the driving of the actuator 164. When the link 162 rotates around the hinge axis, the first contact surface 1622 is always tightly attached to the outer peripheral surface of the hinge axis, so that the door body and the box body are prevented from falling off, and the use satisfaction of a user is improved.
