One embodiment of the present invention provides a hinge device and a refrigerator with the hinge device. By redesigning the structure of the hinge, it is possible to control the upward displacement of the door during the opening process, so that under the same door opening angle, relative to Existing refrigerators have a larger opening area, thereby facilitating opening of the door for easy access.

The hinge device 100 can also be installed on refrigerators, upright refrigerators, wine cabinets, dishwashers, microwave ovens and other equipment. In this embodiment, a refrigerator 1000 is provided, including a door body 200 and a box body 300. The box body 300 The interior 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 housing 10 is fixedly connected to the door body 200, and the lower hinge housing 20 is fixedly connected to the box body 300, as shown in FIG. 2, in order to clearly express the position and direction described in this embodiment, in this embodiment, the Taking the horizontal refrigerator 1000 as an example, it is defined that the opening of the cabinet 300 of the refrigerator 1000 is upward, and the opposite direction is defined as downward. , 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 box body 300, and the two sides facing the box body 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. 4a-8, the shaft can move from one end to the other end 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 .

When the upper hinge housing 10 rotates around the first shaft body 31 and the second shaft body 41 at the same time, the shapes of the first groove body 32 and the second groove body 42 can be designed according to needs, so that the center of rotation of the upper hinge housing 10 falls At the expected design position, the close distance between the first shaft body 31 and the second shaft body 41 will not cause excessive torque, so the hinge can be made thinner. In addition, especially by designing the first groove body 32 and the position and shape of the second groove body 42 can control the movement of the door body 200 conforming to the preset trajectory.

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 .

During at least part of the rotation of the upper hinge housing 10 around the lower hinge housing 20, the upper hinge housing 10 moves in a first direction at the same time, and the first direction has an upward component, that is, the door body 200 in the closed state of the door body 200 is relatively The direction of the box body 300 makes the door body 200 move upwards more during the upward rotation process, and the movement trajectory of the door body 200 is the superposition of the two movements of upward rotation and upward translation.

Take the existing hinge shown in Figure 1 as an example. When the existing hinge is installed on the refrigerator, when the door is fully opened, the distance between any point on the door and the upper surface of the box is h, and in this embodiment the control The door body 200 moves upward at the same time during the overturning process, as shown in Figures 2-3, so that when the door body 200 is opened, the distance from any point on the door body 200 to the upper surface of the box body 300 decreases, and the amount of reduction is represented by h1 That is to say, when the door body 200 of this embodiment is opened, the distance between the point on the door body 200 and the upper surface of the box body 300 is h+h1. You can also refer to the comparison before and after the accompanying drawing 3. The dotted line in the figure is the present Some door positions, the solid line is the door body 200 of this embodiment, the center of the circle in Figure 3 is the position of the instantaneous center of rotation, the door body 200 of this embodiment moves upwards more relative to the existing door body , so that when the door is opened at the same opening angle, for example, when it is also opened at 45°, the door body 200 moves upwards more, so that the cross-sectional area of the opening opened to the user is larger, and more opening area is exposed by turning the same angle, In other words, when the same opening area is exposed, the rotation angle of the door body 200 is less, so that opening the door body 200 saves effort.

As shown in Figures 4a-6b, 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 upward for a certain distance, realizing the effect that the opening area of the refrigerator 1000 is larger under the same rotation angle mentioned above.

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 gravity 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.

During at least part of the rotation of the upper hinge housing 10 around the lower hinge housing 20, the instantaneous center of rotation is located behind the first preset plane, which is a plane that passes through the rear lower end of the door body 200 and is inclined backward and downward. The included angle between a preset plane and the horizontal plane is 45°, as shown in the dotted line in Figure 3 where the existing door body is opened, and when the position of the instantaneous center of rotation is moved to the rear of the first preset plane, this Compared with the existing door body, the door body 200 of the embodiment moves upward more, so that a larger opening area is exposed under the same rotation angle.

In Figures 4a-6b, the design method of the first tank body 32 and the second tank body 42 is such that the position of the instantaneous center of rotation of at least part of the process is set behind the first preset surface according to the above-mentioned needs, so The trajectories of the first trough 32 and the second trough 42 need to make the position of the instantaneous center of rotation meet this requirement. According to the first axis 31 and the second axis 41, both do impure sliding and rolling in the groove and the three-center theorem , the contact position of the first shaft body 31 and the first groove body 32 forms the first common normal line, the contact position of the second shaft body 41 and the second groove body 42 forms the second common normal line, and the instantaneous center of rotation is the first common normal line and the second Intersection point of common normals. Therefore, the trajectory of the first groove body 32 and the second groove body 42 is such that the intersection point of the common normal line at the target position falls behind the first preset surface.

Further, as shown in Figures 4a-6b, the elastic support includes a support beam 73, a support rod 71, and an elastic member 72 sleeved on the outside of the support rod 71, the support beam 73 includes a fixed end connected to the lower hinge shell 20, and the elastic One end of the member 72 is fixed to the support beam 73, and the other end is against the support rod 71. The two ends of the support beam 73 are respectively connected to a pair of opposite side walls of the lower hinge housing 20, an opening is set on the support beam 73, the support rod 71 passes through the opening, the elastic member 72 can be set as a spring, and the upper and lower sides of the spring Both ends can be provided with support sleeves, as shown in Figure 4a, the support sleeve below is offset against the support beam 73 around the opening, and the support sleeve above is offset against the protruding protrusion of the support rod 71.

The spring is always in a compressed state. Under the elastic action of the spring, when the upper hinge housing 10 is turned upward, the support rod 71 moves upward under the drive of the spring, and the spring releases part of the elastic force, and the spring is still in a compressed state, so it can support the upper The opening of the hinge shell 10 saves effort to open the door and supports the hovering of the door body 200 .

There are many ways to implement the specific structure of the elastic support part:

In one of its embodiments:

Two sets of round holes are provided on the connecting piece 50, the first shaft body 31 passes through one set of round holes, and the sliding shaft 61 passes through the other set of round holes, both the first shaft body 31 and the sliding shaft 61 can rotate in the round holes , when the support rod 71 moves upward under the action of the spring, the sliding shaft 61 is pushed to move upward along the stopper 62, the sliding shaft 61 pushes the connecting piece 50 to move, and the connecting piece 50 is connected to the first shaft body 31 to drive the first shaft Body 31 moves, and then supports the movement of upper hinge shell 10.

The limiting portion 62 is configured as a linear groove on a pair of opposite side walls of the lower hinge housing 20 , the extending direction of the groove is the up-down direction, and the sliding shaft 61 moves up and down in the up-down groove. In addition, the limiting portion 62 can also be arranged on the bottom wall connecting the two side walls.

In another embodiment:

The difference from the previous embodiment is that the connecting piece 50 is not connected with the first shaft body 31 or the second shaft body 41, but is connected with the third shaft body 80 on the upper hinge housing 10, as shown in FIG. 7, the first The rotating part or the second rotating part further includes a third shaft body 80 parallel to the first shaft body 31 and the second shaft body 41 , and the third shaft body 80 is fixedly connected to the upper hinge housing 10 .

Since the instantaneous center can be moved, the trajectory of the door body 200 is not simply turned around a fixed point, but there are at least two centers in different positions in space. The door body 200 first rotates around one of the instantaneous centers, and then Rotate around another instantaneous center, so the door body 200 can be made to move more in line with expectations.

Correspondingly, during the movement of the instantaneous center of the upper hinge housing 10, the instantaneous center of rotation of the door body 200 also changes accordingly. Fixed, so the instantaneous center of the upper hinge housing 10 and the lower hinge housing 20, that is, the instantaneous center when the door body 200 rotates around the box body 300, that is, the instantaneous center of rotation of the door body 200 and the box body 300 is in motion. For example, compared to the position of the existing door body in FIG. 1 after being turned over, by controlling the positions of different instantaneous centers, the position of the door body 200 after being turned over and opened can be more forward than the existing position, that is to say, During the rotation process of the door body 200, the position of the instantaneous center of rotation can be changed. During the change process, at least in a certain area, the instantaneous center of rotation can be controlled after the first preset plane, so that the door body 200 can be rotated during the rotation process. , moving forward at least in some positions.
