The rotating connection structure is located between the first fixing part 41 and the second fixing part 51. same side.

This embodiment is the first embodiment of the hinge assembly of the present invention, and the hinge assembly is mainly used in refrigeration appliances. Therefore, the present invention also provides an embodiment of a refrigeration appliance. Of course, the hinge assembly can also be applied to other fields. Specifically, the refrigerating appliance includes a box body 1, an inner door body 2 for opening or closing the box body 1, and an outer door body 3 arranged outside the inner door body 2, wherein the refrigerating appliance also includes a connecting box body 1, The hinge assembly of the inner door body 2 and the outer door body 3, the hinge assembly makes the outer door body 3 and the inner door body 2 can be rotated outwards compared with the box body 1, and the inner door body 2 It is arranged on the outer door body 3 coaxially with the pivot shaft of the outer door body 3 .

Specifically, as shown in FIG. 1 , in this embodiment, the refrigerating appliance is a refrigerator, and the refrigerator may be a traditional top-and-bottom refrigerator, or a side-by-side refrigerator, a French refrigerator, or other refrigerators. Of course, in other embodiments, the refrigeration appliance may also be a refrigerator, a wine cabinet, and the like.

The first fixing part 41 is fixed on the box body 1, and the second fixing part 51 is fixed on the inner door body 2 or the outer door body 3.

The rotation connection structure includes a first hinge shaft 43 extending from the first extension part 42 , and a rotating part 53 formed on the second extension part 52 to rotatably cooperate with the first hinge shaft 43 . The rotating portion 53 is a through hole formed through the second extending portion 52 . Wherein, the first hinge shaft 43 and the outer door body 3 cooperate with each other to rotate, therefore, the inner door body 2 and the outer door body 3 both rotate around the first hinge shaft 43 .

Through the above structure, it is avoided to arrange the first hinge shaft 43 on the inner door body 2, thereby reducing the thickness of the inner door body 2, so that the overall volume of the refrigeration appliance is reduced, which is beneficial to miniaturization design. And when the first hinge shaft 43 is arranged on the outer door body 3, when the inner and outer doors are opened simultaneously, or when the outer door body 3 is opened separately, the distance from the side wall of the box body 1 can be significantly reduced when the door body is overturned, thereby reducing There is no risk of collision with the wall after the door body is opened. At the same time, due to the small protrusion distance, the refrigeration appliance can be further installed close to the wall, making full use of the space and improving the space utilization rate.

Specifically, the above-mentioned protruding distance from the side wall of the box body 1 is roughly the distance between the first hinge shaft 43 and the front end surface of the outer door body 3, and if the first hinge shaft 43 is arranged on the inner door body 2, the above-mentioned protruding The distance from the side wall of the box body 1 is roughly the distance from the first hinge axis 43 to the front end of the outer door body 3 , but this distance includes the thickness of the entire outer door body 3 and part of the thickness of the inner door body 2 . Therefore, by comparison, it is obvious that when the first hinge shaft 43 is disposed on the outer door body 3, the distance protruding from the side wall of the box body 1 is smaller.

Moreover, the thickness of the outer door body 3 on the side of the first hinge 4 and the second hinge 5 is greater than the thickness of the inner door body 2 on the side of the first hinge 4 and the second hinge 5 . Therefore, the overall thickness of the door body can be reduced, the cost of the door body can be reduced, and the overall volume of the refrigeration appliance can also be reduced.

The hinge assembly further includes a bushing 6 disposed between the first hinge 4 and the second hinge 5, the bushing 6 has a main body portion 61 extending in the same direction as the first extension portion 42 and the second extension portion 52, The shaft portion 62 extending from the main body portion 61 is located between the first hinge shaft 43 and the through hole. And the main body portion 61 is fixed to the first hinge 4 or the second hinge 5 .

The bushing 6 is made of plastic, while the first hinge 4 and the second hinge 5 are made of metal. In addition, the main body 61 is fixed together with the first hinge 4 or the second hinge 5 to prevent the shaft sleeve 6 from being in an active state. Of course, in other embodiments, the bushing 6 can also be a hollow tubular structure, and it only needs to be provided with an outwardly protruding structure at the upper end so as to hang on the through hole. Therefore, the first hinge 4 and the second hinge 5 are separated by the bushing 6 , avoiding direct contact between the first hinge 4 and the second hinge 5 , thereby reducing the noise generated during rotation.

In this embodiment, the first hinge shaft 43 has a through hole 44 penetrating in the height direction, and the through hole 44 is penetrating in the radial direction. Therefore, when the first hinge shaft 43 cooperates with the shaft sleeve 6 and the outer door body 3, it can be better attached to it, thereby eliminating the gap between the first hinge shaft 43 and the shaft sleeve 6 and the outer door body 3. gap to prevent the door from shaking.
