In order to make the assembly of the hinge, the hovering structure and the first rim and the hovering function of the door body of the present invention more detailed, the following will be described in detail.

FIG. 8 is a schematic view of the hinge, the hovering structure and the first frame in an assembled state according to the present invention; FIG. 9 is an enlarged schematic view of region B of FIG. 8; FIG. 10 is a schematic view of the hinge, the hovering structure and the first frame of the present invention in an assembled state; fig. 11 is an enlarged schematic view of region C in fig. 10.

As shown in fig. 8 to 11, the hovering structure 300 is first assembled in the accommodating portion 126 of the first frame 121, wherein the mounting plate 301 of the hovering structure 300 enters the first opening 127, two ends of the mounting plate 301 are supported by the supporting

structures

1261 and 1262 located at the top of the accommodating portion 126 (or the hollow structure), so that the hovering structure 300 is located in the accommodating portion 126, the supporting

structures

1261 and 1262 may be bumps disposed in the hollow structure or top ends of at least one side wall of the hollow structure, and in order to increase the bonding strength between the hovering structure 300 and the first frame 121, the mounting plate 301 and the first frame 121 may be fixed by screw locking or the like; the hovering body 302 and the elastic expansion element of the hovering structure 300 are received in the receiving space of the receiving portion 126 (or the hollow structure), and the protrusion 304 of the elastic expansion element at least partially protrudes from the second opening 128.

The second connecting portion 202 of the hinge 200 is assembled to the first frame 121, the hinge shaft 203 on the second connecting portion 202 enters the pivot hole 125, the second connecting portion 202 at least partially covers the mounting plate 301, the second connecting portion 202 is fixedly connected to the concave portion of the first frame 121, wherein the limiting groove 204 on the hinge shaft 203 is opposite to the convex portion 304 of the hovering structure 300, and the convex portion 304 at least partially enters the limiting groove 204 (as shown in fig. 11). The door 120 can suspend due to the cooperation of the limiting groove 204, the protrusion 304 and the elastic member 306. Specifically, in the process that the door 120 rotates around the hinge shaft 203, the hovering structure 300 moves along the same path relative to the hinge shaft 203, when the elastic expansion assembly moves to the limiting groove 204, the elastic member 306 changes from a compressed state to an extended state, the protrusion 304 is pushed into the limiting groove 204, that is, the protrusion 34 is clamped into the limiting groove 204, rotational resistance is generated, the door 120 hovers and cannot be automatically closed, and when the door 120 rotates again, the door needs to be rotated by overcoming the resistance, and the resistance enables the door 120 not to be automatically closed. When the refrigerator door body is subjected to external force to overcome the resistance to continue moving, the limiting groove 204 presses the convex part 304, so that the elastic part 306 is compressed, the convex part 304 exits from the limiting groove 204, and the door body 120 continues moving. When the door 120 continues to move and the convex part 304 of the hovering structure 300 enters the other limiting groove of the hinge shaft 203, the resistance formed by the convex part 304 and the other limiting groove enables the door 120 to be hovered at another opening angle and cannot be automatically closed.

With continued reference to fig. 5, in this embodiment, the limit groove 204 is a V-shaped groove, which is a continuous strip-shaped groove disposed along a direction parallel to the axis of the hinge shaft 203. It should be noted that the shape and number of the limiting grooves 204 are not particularly limited in the present invention, for example, the number of the limiting grooves 204 on the hinge shaft 203 is greater than or equal to one, and the limiting grooves 204 may also be concave arc grooves.

In summary, the invention provides a first frame of a refrigerator door with an accommodating portion for accommodating a hovering structure, which improves the assembly convenience of the hovering mechanism of the refrigerator door.

It should be understood that although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description is for clarity only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can also be combined appropriately to form other embodiments understood by those skilled in the art.

The above list of details is only for the concrete description of the feasible embodiments of the present application, they are not intended to limit the scope of the present application, and all equivalent embodiments or modifications that do not depart from the technical spirit of the present application are intended to be included within the scope of the present application.
