As shown in fig. 2, in order to clearly express the position and direction described in this embodiment, taking a horizontal refrigerator 1000 as an example, the opening of the refrigerator 1000 is defined to be upward, and the opposite direction is defined as downward, the door 200 is located above the refrigerator 300, the user is located on one side of the refrigerator 300 away from the hinge device 100 to operate the refrigerator 1000, the user is defined to be located in front of the refrigerator 1000, the hinge device 100 is located behind the refrigerator 300, and left and right are respectively defined from the front to two sides of the refrigerator 300.

The first shaft 31 can slide out a distance in the first slot 32 and the second shaft 41 can slide out a distance in the second slot 42, i.e. the first slot 32 and the second slot 42 are not circular slots but slots with a length, as shown in fig. 4 a-8, the shaft can move from one end to the other end in the slots. In the process of sliding the first shaft body 31 and the second shaft body 41, the upper hinge shell 10 is turned around the lower hinge shell 20, and in the whole turning process, the upper hinge shell 10 does not always rotate around the first shaft body 31 or the second shaft body 41, but is turned over under the limitation of the first shaft body 31, the first groove body 32, the second shaft body 41 and the second groove body 42.

In addition, the first shaft body 31 and the second shaft body 41 of the present embodiment are merely distinguished as names, and similarly, the first groove body 32 and the second groove body 42 are also distinguished as names for explaining that there are two shafts that can slide a distance in the grooves. The second shaft 41 may also be referred to as the first shaft 31, and the second groove 42 may also be referred to as the first groove 32.

The upper hinge shell 10 has a first position, a second position and a third position, and in the process that the upper hinge shell 10 moves from the first position to the second position, the upper hinge shell 10 rotates around the first shaft body 31; during the movement of the upper hinge housing 10 from the second position to the third position, the upper hinge housing 10 rotates about the second shaft body 41.

During at least part of the rotation of the upper hinge shell 10 around the lower hinge shell 20, the upper hinge shell 10 can move towards the designed direction at the same time, and the shapes of the first slot 32 and the second slot 42 are designed according to the requirement of the motion track of the upper hinge shell 10.

In at least a part of the process that the upper hinge shell 10 rotates around the lower hinge shell 20, the upper hinge shell 10 simultaneously moves towards the first direction, the first direction has a downward component, that is, the direction of the refrigerator body 300 relative to the door body 200 in the closing state of the door body 200, so that the door body 200 simultaneously moves downwards in the process of turning over and opening, and the movement track of the door body 200 is the superposition of two movements of upward rotation and downward translation.

The first shaft body 31 and/or the second shaft body 41 are located in front of a first preset surface, the first preset surface is a plane which passes through the rear lower end of the door body 200 and is inclined towards the rear lower side, an included angle between the first preset surface and a horizontal plane is 45 degrees, as shown in fig. 3, a dotted line in the figure is a position where the existing door body is opened, and when the position of the instant center of rotation is moved to the front of the first preset surface, the door body 200 of the embodiment can be driven to move downwards more relative to the existing door body.

Taking the existing hinge in fig. 1 as an example, when the existing hinge is installed on a refrigerator, after the door body is completely opened, the distance between any point on the door body and the upper surface of the refrigerator body is h, and in this embodiment, the door body 200 is controlled to move downward in the process of overturning, as shown in fig. 2 to 3, when the door body 200 is opened, the distance between any point on the door body 200 and the upper surface of the refrigerator body 300 is reduced by h1, that is, when the door body 200 in this embodiment is opened, the distance between the point on the door body 200 and the upper surface of the refrigerator body 300 is h-h1, see also the front-back comparison in fig. 3, the dotted line in the figure is the existing door body position, the solid line is the door body 200 in this embodiment, the circle center in fig. 3 is the position of the instant center of rotation, the door body 200 in this embodiment moves downward more than the existing door body, the requirement of the door body 200 for the amount of space above the refrigerator 1000 is reduced, when the refrigerator is above a wall, the door body 200 can also move downward as much as possible to avoid obstacles, and the influence of the opening angle of the door body above the refrigerator 1000 is reduced.

As shown in fig. 4a to 6b, it is shown that the hinge device 100 sequentially rotates from the initial position to the position where the upper hinge housing 10 is fully opened, and when the upper hinge housing 10 is turned over to the right position, the upper hinge housing 10 of this embodiment moves downward for a certain distance relative to the existing hinge that does pure rotation, that is, the upper hinge housing moves downward while opening the door body 200.

In addition, the elastic support portion includes a fixed end fixedly connected to the lower hinge housing 20, a receiving end connected to the first rotating portion or the second rotating portion, and an elastic support member disposed between the fixed end and the receiving end. One end of the elastic supporting piece is supported at the fixed end, and the other end of the elastic supporting piece is connected to the first rotating part or the second rotating part, so that the elastic supporting piece can support the first rotating part or the second rotating part and plays a role in supporting the door body 200 to suspend.

The elastic supporting part is supported by the fixed end, the sliding end moves parallel to the connecting plate of the box body 300 along with the movement of the sliding shaft 61, namely, the movement in the direction vertical to the connecting plate of the box body 300 is avoided, the moving space required in the box body is reduced, the thickness of the hinge can be reduced, in the upward opening process of the door body 200, the downward force of the door body 200 is applied to the first rotating part and the second rotating part, and the elastic supporting part is connected with the first rotating part or the second rotating part to support the first rotating part or the second rotating part.
