The refrigerator can preserve fresh food, extend the storage time of food, improve the safety of food consumption, and is a necessary household appliance. At present, refrigerators realize the rotation of the door body through hinges to achieve the purpose of opening and closing the door. During use, the refrigerator door body will be in a state of free movement after opening to a certain angle, and the user needs to fix the door body with one hand when taking and placing items, and the other hand to pick up and place the items, which is very inconvenient. In addition, there may also be cases where the door body collides with a foreign object when the door is opened due to the opening angle of the refrigerator door body being too large. Based on this, in order to solve how to make the refrigerator door body in the set opening angle can be rotated to make the items easy to take and place, now some high-end double-door refrigerators have achieved this function, but for the cross-door refrigerator, this technology is still a blank, the existing scheme can not be transplanted to the cross-door refrigerator, because the double-door refrigerator when opening 90 ° screw stop, the door body will be displaced upwards 4~6mm, but the gap between the middle hinge of the cross-door refrigerator and the upper trim strip of the lower door body can not be so large, So new technologies need to be studied to solve this problem.
The object of the first aspect of the present invention is to overcome at least one defect of the existing refrigerator door body hovering, to provide a hinge assembly for the refrigerator door body, to solve the problem that the lower door body of the cross door refrigerator cannot be swirled due to insufficient middle hinge clearance, and can at least make the door body on the lower side of the cross door rotate to make the items easy to access and place.
The second aspect of the present invention is intended to provide a refrigerator having the hinge assembly described above. According to a first aspect of the present invention, the present invention provides a hinge assembly for the refrigerator door body, comprising a first connecting member and a second connecting portion, the first connecting member and the second connecting member are optionally disposed in the refrigerator box, and the other is disposed in the refrigerator door body to connect the box body and the door body; wherein the first connection part comprises a bushing housing, a first cam structure and an elastic reset device; the first cam structure is movably disposed along the axis direction of the bushing housing, and the first cam structure has a first base, and one or more first protruding portions extending from the first base along the axis direction of the bushing housing are spaced along the circumferential direction of the bushing housing; the elastic reset device is disposed in the bushing housing, and is in contact with the side of the first base that deviates from the first convex portion; The second connecting portion comprises a rotating shaft and a second cam structure; the second cam structure having a second base disposed at the second base of the shaft, and one or more second protrusions spaced along the circumferential direction of the shaft extending from the second base along the axis direction of the shaft; and the shaft is configured to be installed in the first connection portion, and is arranged coaxially with the bushing housing; Each second convex portion is configured to be disposed on one side of the first convex portion, and when the second convex portion rotates relative to the first convex portion, the second convex portion moves along the first convex portion and may move to a position where the convex end face of the second convex portion is in contact with the convex end face of the first convex portion, and prompts the first cam structure to move along the axis of the shaft, and the first cam structure compresses the elastic reset device.
