That is to say, during the whole opening process of the hinge assembly 30 , the second hinge member 32 first rotates relative to the first hinge member 31 along the first rotation axis P1 , and then rotates relative to the first hinge member 31 along the second rotation axis P2 .

In this embodiment, the second rotation axis P2 is a fixed axis, and the second rotation axis P2 is a virtual axis.

Here, "the second rotation axis P2 is a fixed axis" means that the position of the second rotation axis P2 is always fixed, that is, the relative position between the second rotation axis P2 and the box body 10 or the door body 20 is fixed.

In other embodiments, the hinge assembly 30 may only include the first rotation axis P1 or the second rotation axis P2, and the forms of the first rotation axis P1 and the second rotation axis P2 are not limited to the above description, that is, the first rotation axis The P1 and the second rotation axis P2 can be optionally fixed axes, non-fixed axes, virtual axes or physical axes according to actual conditions (the real axes are defined as the components actually included in the hinge assembly 30 ).

In this embodiment, referring to Fig. 5 to Fig. 13 , when the hinge assembly 30 is in the process of opening from the closed state to the first opening angle α1, the second hinge member 32 is relative to the first rotation axis P1 as the central axis. When a hinge member 31 rotates, the first shaft body 311 and the second shaft body 312 slide in the slide groove 40 at the same time to drive the door body 20 to generate a translation relative to the box body 10 .

That is to say, at this time, the first shaft body 311 and the second shaft body 312 rotate around the first rotation axis P1 at the same time.

Here, "the amount of translation of the door body 20 relative to the box body 10" means that the door body 20 also has a translation amount during the process of rotating relative to the box body 10. When corresponding to a refrigerator, the translation amount refers to the amount of horizontal movement. That is, in addition to the door body 20 rotating relative to the box body 10 , the door body 20 also generates a horizontal movement relative to the box body 10 .

Next, various specific examples of the motion track of the door body 20 will be introduced.

In the first specific example, referring to FIG. 14 and FIG. 15 , the box body 10 includes an accommodating chamber D and a pivoting side P connected to the hinge assembly. When the hinge assembly 30a is in the process of opening from the closed state to the first opening angle α1 , the door body 20 moves from the pivoting side P toward the accommodation chamber D.

When the hinge assembly 30a is in a closed state, the second shaft body 312 is located at the start end B1, and the first shaft body 311a is located at the first chute 321a away from the second chute 322a. When the hinge assembly 30a is in the process of opening from the closed state to the first opening angle α1, the first shaft body 311a moves in the first chute 321a and drives the second shaft body 312 to move from the starting end B1 to the end point B2 , the door body 20 moves from the pivoting side P toward the accommodating chamber D.

That is to say, when there is a cabinet next to the refrigerator, the door body 20 moves from the pivoting side P toward the accommodating chamber D, that is, the door body 20 moves a certain distance away from the cabinet, so as to prevent the door body 20 from colliding with the cabinet during the initial opening process. interfere with each other.

Here, the door body 20 includes a front wall 21 away from the accommodating chamber D and a side wall 22 always interposed between the front wall 21 and the accommodating chamber D. When the second hinge member 32 is connected to the door body 20, the starting end B1 It is farther away from the front wall 21 and the side wall 22 than the end B2.

It should be noted that, in this specific example, the first opening angle α1 is the maximum opening angle, and the first shaft 311a moves from the initial end A1 to the stop end A2 and drives the second shaft 312a to move from the starting end B1 to the end B2 , the stop end A2 coincides with the start end B1, and the door body 20 moves from the pivoting side P toward the accommodation chamber D.

In other examples, the stop end A2 may not coincide with the start end B1, for example, the stop end A2 is located on a side of the start end B1 away from the end B2.

In the second specific example, referring to Fig. 16 to Fig. 18, the second chute 322b includes a start end B1 and an end B2, and the first chute 321b includes a connected first part M1 and a second part M2, when the hinge assembly 30b is in the closed position When the state is opened to the first intermediate opening angle α11, the second shaft body 312b remains at the starting end B1, and the first shaft body 311b moves in the first part M1 with the second shaft body 312b as the central axis. When the hinge assembly 30b In the process of continuing to open from the first intermediate opening angle α11 to the first opening angle α1, the first shaft body 311b moves in the second part M2 and drives the second shaft body 312b to move from the starting end B1 to the end B2, and the door body 20b moves from the pivot side P towards the accommodation chamber D.

That is to say, the door body 20 first rotates at a certain angle, and then moves away from the cabinet 200 for a certain distance, so as to prevent the door body 20 from interfering with the cabinet 200 during the initial opening process.

Here, in a side-by-side refrigerator or a multi-door refrigerator with vertical beams, there are left and right doors arranged side by side, and the door body 20 is first rotated at a certain angle to prevent the left and right doors from interfering with each other.

It should be noted that, in this specific example, the first opening angle α1 is the maximum opening angle, and the first shaft 311b moves from the initial end A1 to the stop end A2 and drives the second shaft 312b to move from the starting end B1 to the end B2 , the stop end A2 coincides with the start end B1, the door body 20 first rotates in place, and then moves from the pivot side P toward the accommodation chamber D.

In the third specific example, referring to FIG. 19 to FIG. 21 , when the hinge assembly 30c is in the process of opening from the closed state to the first opening angle α1, the second hinge member 32c is relative to the first rotation axis P1 as the central axis. When a hinge 31c rotates, the first shaft body 311c and the second shaft body 312c slide in the chute 40c at the same time to drive the door body 20 to generate a translation relative to the box body 10.
