The hinge device 100 can be installed on refrigerators 1000, refrigerators, upright refrigerators, wine cabinets, dishwashers, microwave ovens and other equipment. In this embodiment, a refrigerator 1000 is provided, which includes a door body 200 and a box body 300. The inside of the body 300 encloses a cooling space, and the door body 200 closes the cooling space. The door body 200 and the box body 300 are connected by a hinge device 100 , and the hinge device 100 supports the opening and closing of the door body 200 .

The hinge device 100 of this embodiment includes a lower hinge housing 20 , an upper hinge housing 10 , a first rotating part, a second rotating part and an elastic support part. The first rotating part includes a first groove body 32 and a first shaft body 31 , the first groove body 32 limits the sliding distance of the first shaft body 31 ; the second rotating part includes a second groove body 42 and a second shaft body 41 , the second groove body 42 defines the sliding distance of the second shaft body 41 , and the upper hinge housing 10 is rotatably connected to the lower hinge housing 20 through the first rotating part and the second rotating part.

The upper hinge shell 10 is fixedly connected to the door body 200, and the lower hinge shell 20 is fixedly connected to the box body 300, as shown in Figures 3 to 5, in order to clearly express the position and direction described in this embodiment, in this embodiment , taking the horizontal freezer 1000 as an example, it is defined that the opening of the cabinet 300 of the freezer 1000 is upward, and the opposite direction is defined as downward, the door 200 is located above the cabinet 300, and the user operates on the side of the cabinet 300 away from the hinge device 100 For the refrigerator 1000, it is defined that the user is located in front of the refrigerator 1000, the hinge device 100 is located at the rear of the cabinet 300, and the two sides facing the cabinet 300 from the front are respectively defined as left and right.

The first shaft body 31 can slide a certain distance in the first groove body 32, and the second shaft body 41 can slide a certain distance in the second groove body 42, that is to say, the first groove body 32 and the second The groove body 42 is not a circular groove, but a groove with a certain length, as shown in Fig. 5 or 6a, the shaft can move from one end to the other in the groove. During the sliding process of the first shaft body 31 and the second shaft body 41, the flipping of the upper hinge case 10 around the lower hinge case 20 is realized. During the whole flipping process, the upper hinge case 10 does not always simply go around the first shaft body 31 or the second shaft body 41 rotates, but is simultaneously overturned under the restriction 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 in this embodiment are only used to distinguish names. A shaft that slides a distance in a groove. The second shaft body 41 can also be called the first shaft body 31 , and the second slot body 42 can also be called the first slot body 32 .

The upper hinge case 10 has a first position, a second position and a third position. When the upper hinge case 10 moves from the first position to the second position, the upper hinge case 10 rotates around the first shaft body 31; During the movement of the shell 10 from the second position to the third position, the upper hinge shell 10 rotates around the second shaft 41 . Figures 6a and 6b correspond to the first position, Figures 7a and 7b correspond to the second position, and Figures 8a and 8b correspond to the third position, when the upper hinge housing 10 is in the third position, the door body 200 can be in a fully open state.

During at least part of the rotation of the upper hinge housing 10 around the lower hinge housing 20, the upper hinge housing 10 can move in a designed direction at the same time, and the first groove body 32 and the second groove body are designed according to the needs of the upper hinge housing 10 movement track. 42 shapes.

During at least part of the rotation of the upper hinge housing 10 around the lower hinge housing 20 , the upper hinge housing 10 simultaneously moves in a first direction, and the first direction has a component along the direction of the lower hinge housing 20 towards the box body 300 . In this embodiment, along the direction of the lower hinge shell 20 toward the box body 300, that is, pointing from the rear to the front, the door body 200 moves forward at the same time during the rotation process. It can be understood that the movement track of the door body 200 is upward. The superposition of two motions of rotation and forward translation.

The first shaft body 31 and/or the second shaft body 41 are located in front of the first predetermined plane, the first predetermined plane is a plane that passes through the rear lower end of the door body 200 and slopes upward and backward, the first predetermined plane and the horizontal plane The included angle is 45°. When the position of the first shaft body 31 and/or the second shaft body 41 is moved to the front of the first preset surface, the door body 200 of this embodiment can be further improved compared with the existing door body. More ground drives the forward movement, so that the length of the door body 200 protruding backward is reduced, and the occupation of the rear space is reduced.

Take the existing hinges in Figures 1 and 2 as an example. When the existing hinges are installed on the refrigerator, when the door is opened, the distance between the position on the door farthest from the box and the rear wall of the box is , generally 60mm, that is to say, when the door is closed, the distance between the box and the rear wall should be at least 60mm.

In this embodiment, the door body 200 is controlled to move forward at the same time during the overturning process, as shown in Figures 3 to 5, so that when the door body 200 is opened, the position of the door body 200 farthest from the box body 300 is the same as that behind the box body 300. The distance between the walls is shortened to about 30mm, so that when the freezer 1000 is placed, the distance between the rear side of the freezer 1000 and the wall can be controlled at about 30mm, which greatly reduces the space that needs to be reserved behind the freezer 1000 and reduces the space A waste of size.

As shown in Figures 6a-8b, it shows that the hinge device 100 rotates from the initial position to the position where the upper hinge shell 10 is fully opened. The upper hinge shell 10 has moved forward for a certain distance, so as to realize the above-mentioned reduction of the space occupied by the rear side.

In addition, the elastic supporting part includes a fixed end fixedly connected to the lower hinge shell 20 , a receiving end connected to the first rotating part or the second rotating part, and an elastic supporting member disposed between the fixed end and the receiving end. One end of the elastic support is supported on the fixed end, and the other end is connected to the first rotating part or the second rotating part, which can support it and play a role in supporting the door body 200 to hover.

Under the support of the fixed end of the elastic support part, the sliding end moves parallel to the connecting plate of the box body 300 with the movement of the sliding shaft 61, that is, the movement in the direction perpendicular to the connecting plate of the box body 300 is avoided, so that the internal required activities The space is reduced, and the thickness of the hinge can be made thinner. When the door body 200 is opened upwards, the downward force of the door body 200 is applied to the first rotating part and the second rotating part. The elastic support and the first rotating part or the second rotating part The rotating part is connected to support it.
