Technical Field

[0003] The present application relates to the technical field of hinges, and in particular to a refrigerator hinge. Background Art

[0004] The refrigerator door body includes a door panel and a door exterior panel fixed on the door panel. The refrigerator door body is thicker due to the cooperation between the door exterior panel and the door panel. When the refrigerator door body is thicker, if the cooperation gap between the refrigerator door body and the cabinet body is small, when the refrigerator door body is opened, one end of the refrigerator door body is likely to collide with the cabinet body, causing the refrigerator door body to be easily damaged. Therefore, the cooperation gap between the refrigerator door body and the cabinet body needs to be set too large to avoid interference between the refrigerator door body and the refrigerator cabinet body when the refrigerator door body is opened.

[0005] Conventional refrigerator hinges include a second connecting member, a first connecting member rotatably connected to the second connecting member, and a second connecting member fixed to the refrigerator cabinet. The first connecting member is hingedly connected to the entire refrigerator door. If the gap between the refrigerator door and the refrigerator cabinet is small, one end of the door exterior panel may easily interfere with the refrigerator cabinet when the refrigerator door is opened. In addition, due to processing errors, after the door exterior panel is assembled, the assembly personnel may also cause interference with the refrigerator cabinet when adjusting and opening the refrigerator door. Summary of the Invention

[0006] The purpose of this application is to provide a refrigerator hinge, in which a reversing transmission assembly is provided on the first connecting member and is connected to the outer panel of the door. When the refrigerator door panel is opened and closed, the outer panel of the door slides on the door panel, so that the outer panel of the door will not interfere with the refrigerator cabinet when the refrigerator door panel is opened, and the matching gap between the refrigerator door panel and the refrigerator cabinet does not need to be set too large. In addition, the processing accuracy requirements of the outer panel of the door can be reduced.

[0007] A refrigerator hinge includes a first connecting member connected to the refrigerator door panel, a second connecting member connected to the refrigerator cabinet, and a third connecting member connected to the refrigerator door exterior panel. A transmission mechanism is provided between the first connecting member, the second connecting member, and the third connecting member. The refrigerator door exterior panel and the refrigerator door panel are arranged in a stacked manner. The first connecting member drives the refrigerator door panel to open and close on the refrigerator cabinet through the transmission mechanism, and the third connecting member drives the refrigerator door exterior panel to slide on the refrigerator door panel during the opening and closing process of the refrigerator door panel through the transmission mechanism.

[0008] The first connecting member is provided with a reversing transmission assembly that is connected to the outer door panel. When the refrigerator door panel is opened and closed, the outer door panel slides on the door panel. In this way, the outer door panel will not interfere with the refrigerator cabinet when the refrigerator door panel is opened. The matching gap between the refrigerator door panel and the refrigerator cabinet does not need to be set too large. In addition, the processing accuracy requirements of the outer door panel can be reduced.

[0009] The first connecting member is hinged to the second connecting member, and the transmission mechanism includes a rotating shaft arranged between the first connecting member and the second connecting member. The first connecting member is positioned and rotated on the second connecting member through the rotating shaft, so that the refrigerator door panel connected to the first connecting member can be rotated to open and close on the refrigerator cabinet.

[0011] The connecting rod and the rotating shaft are arranged between the first connecting member and the second connecting member at intervals;

[0012] When the refrigerator door panel is opened toward the refrigerator cabinet through the first connecting member, the first connecting member drives the connecting rod and the reversing transmission assembly to move, and the reversing output end of the reversing transmission assembly acts on the third connecting member, so that the outer door panel connected to the third connecting member slides on the refrigerator door panel in a direction away from the refrigerator cabinet when the refrigerator door panel is opened;

[0013] When the refrigerator door panel is closed toward the refrigerator cabinet through the first connecting member, the first connecting member drives the connecting rod and the reversing transmission assembly to move, and the reversing output end of the reversing transmission assembly acts on the third connecting member, so that the outer door panel connected to the third connecting member slides on the refrigerator door panel toward the refrigerator cabinet when the refrigerator door panel is closed.

[0014] When the refrigerator door panel rotates and opens, the connecting rod drives the door exterior panel to move outward at the same time, effectively preventing the door exterior panel from interfering with the refrigerator cabinet when the refrigerator door panel is opened, and avoiding damage to the door exterior panel.

[0015] A limiting slide is provided on the first connecting member, and a limiting column connected to the reversing transmission assembly is provided at the second end of the connecting rod. When the refrigerator door panel is opened and closed toward the refrigerator cabinet through the first connecting member, the limiting column of the connecting rod limits the movement on the limiting slide and drives the reversing transmission assembly to move.

[0016] The reversing transmission assembly is moved on the first connecting piece by sliding the limiting column on the limiting sliding groove.

[0019] The sliding directions of the slider and the third connecting member are opposite. The slider is provided with a first meshing tooth that meshes with the gear, and the third connecting member is provided with a second meshing tooth that meshes with the gear. When the slider slides, it drives the gear to rotate, and when the gear rotates, it drives the third connecting member and the door exterior panel to slide.

[0020] A first linear sliding connection fitting position is provided between the slider and the first connecting member, and the slider is linearly slidably arranged on the first connecting member through the first linear sliding connection fitting position. A second linear sliding connection fitting position is provided between the third connecting member and the first connecting member, and the third connecting member is linearly slidably arranged on the first connecting member through the second linear sliding connection fitting position.

[0021] The first connecting member is provided with a rotating column matched with the gear. When the gear rotates, it is positioned and rotated on the first connecting member through the rotating column.

[0022] The first connecting member is provided with a bottom cover for encapsulating the gear, the slider and the third connecting member on the inner cavity of the first connecting member.

[0023] An opening is provided at the connection between the first connecting member and the third connecting member and the door exterior panel. The third connecting member is provided with a fixed block that cooperates with the door exterior panel. When the third connecting member and the door exterior panel slide, the fixed block slides on the opening to effectively control the maximum sliding displacement of the door exterior panel during the opening and closing process of the refrigerator door panel.

[0024] The beneficial effects of this application are as follows:

[0025] The first connecting member is provided with a reversing transmission assembly that is connected to the outer door panel. When the refrigerator door panel is opened and closed, the outer door panel slides on the door panel. In this way, the outer door panel will not interfere with the refrigerator cabinet when the refrigerator door panel is opened. The matching gap between the refrigerator door panel and the refrigerator cabinet does not need to be set too large. In addition, the processing accuracy requirements of the outer door panel can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS
