In this embodiment, as shown in FIG. 1 , the hinge assembly is as shown in FIG. 1 . 100 is used to connect the door body 10 of the refrigerator and the cabinet 20. In order to achieve greater space utilization, in modern homes, the refrigerator is often embedded in the design, or the refrigerator is placed against the wall, cabinet, etc. In the above case, in the existing refrigerator, since the door body is thick and rotates around an axis during the door opening process, the refrigerator door easily touches the obstacle of the refrigerator case 20 during the rotation process, and thus is used. Very inconvenient. Therefore, the hinge assembly 100 in the present invention can cause the door body 10 to move in accordance with a preset trajectory during opening or closing so that the door body 10 does not touch an obstacle. In the present embodiment, the side of the case 20 near the hinge assembly 100 is referred to as a side surface. For the convenience of description, the extended surface of the side surface is referred to as an obstacle, and the door body 10 cannot be touched during the opening and closing process. When the obstacle is encountered, that is, during the opening and closing of the door body 10, the door body 10 cannot touch the extended surface of the side surface.

Specifically, during the opening process of the door body 10, the first stage of rotating the door body 10 and moving away from the hinge assembly 100 is performed, and then the second stage of the door body 10 is only rotated; when the door body 10 is closed In the process, the second stage in which the door body 10 is rotated is first performed, and then the first stage in which the door body 10 rotates and moves toward the hinge assembly 100 is performed. During the opening and closing of the door body 10, the movement of the hinge assembly 100 is completely opposite.

具体的,如图2、图3及图5所示,所述铰链组件100包括:Specifically, as shown in FIG. 2, FIG. 3 and FIG. 5, the hinge assembly 100 includes:

In the present embodiment, "fully open" means that the door body 10 is opened to be perpendicular to when the door body 10 is closed.

另外,所述门体10在关门的过程中与上述过程完全相反,先经过第二阶段,再经过第一阶段,具体不再详述。In addition, the door body 10 is completely opposite to the above process in the process of closing the door, first passes through the second stage, and then passes through the first stage, and details are not described in detail.

另外,在本实施方式中,所述铰链轴2设置于所述传动轴3远离箱体20的一侧,从而才能在门体10绕着铰链轴2旋转时带动传动轴3旋转。并且所述限位轴41设置于所述铰链轴2和传动轴3之间,从而可减小所述传动件4的运动路径,并且同样可以达到本发明的技术效果。In addition, in the present embodiment, the hinge shaft 2 is disposed on a side of the transmission shaft 3 away from the casing 20 so as to drive the transmission shaft 3 to rotate when the door body 10 rotates around the hinge shaft 2. And the limiting shaft 41 is disposed between the hinge shaft 2 and the transmission shaft 3, so that the moving path of the transmission member 4 can be reduced, and the technical effect of the present invention can also be achieved.
