In the first embodiment of the present invention, the engaging portion 40 is described as an example of the chute 40.

The sliding groove 40 may penetrate through the second hinge member 32 in the thickness direction of the second hinge member 32, that is, the sliding groove 40 is a through hole, or the side of the sliding groove 40 away from the first hinge member 31 is a closed area, that is, the sliding groove 40 is a groove.

The sliding slot 40 includes a first sliding slot 321 and a second sliding slot 322 that are connected to each other, and when the hinge assembly 30 is in an opening process, the first shaft 311 moves in the first sliding slot 321, and the second shaft 312 moves in the second sliding slot 322.

Here, the first shaft 311 moves in the region defined by the first sliding groove 321, the second shaft 312 moves in the region defined by the second sliding groove 322, and the phrase "the sliding groove 40 includes the first sliding groove 321 and the second sliding groove 322 which are communicated with each other" means that the first sliding groove 321 and the second sliding groove 322 are connected with each other, no space region exists between the first sliding groove 321 and the second sliding groove 322, and the sliding groove 40 has a whole through groove structure.

In addition, the "hinge assembly 30 is in the opening process" means that the second hinge member 32 is opened in a direction away from the first hinge member 31, that is, the second hinge member 32 is applied in a direction to drive the second hinge member 32 to move in a direction away from the first hinge member 31, and when the hinge assembly 30 is mounted on the refrigerator 100, the opening process of the hinge assembly 30 corresponds to the opening process of the door 20.

When the hinge assembly 30 is at the maximum opening angle, the first shaft 311 is located at the stopping end a2 of the first sliding slot 321, and the stopping end a2 is located in the second sliding slot 322.

Here, the hinge assembly 30 is at the maximum opening angle corresponding to the door 20 being opened to the maximum opening angle, and the "stop end a2 is located in the second sliding slot 322" means that the stop end a2 is located at the end or middle position of the second sliding slot 322.

The first sliding groove 321 and the second sliding groove 322 of the present embodiment are communicated with each other, so that the space of the second hinge 32 occupied by the whole sliding groove 40 can be reduced, and the integrated sliding groove 40 is convenient for molding, so that the molding process of the hinge assembly 30 can be greatly reduced.

In addition, the hinge assembly 30 of the present embodiment includes two shaft bodies, and compared to a single-shaft hinge assembly, the present embodiment can change the motion trajectory of the door body to adapt to different application scenarios.

In the present embodiment, the movement locus of the first shaft 311 partially overlaps the movement locus of the second shaft 312.

Here, the movement locus of the first shaft body 311 means all movement loci of the first shaft body 311 during the entire opening process of the hinge assembly 30, the movement locus of the second shaft body 312 means all movement loci of the second shaft body 312 during the entire opening process of the hinge assembly 30, and the "partially overlapping" means that the first shaft body 311 passes through a partial region through which the second shaft body 312 passes during the entire opening process of the hinge assembly 30.

Thus, a section of the sliding groove 40 is a common area of the first shaft 311 and the second shaft 312, which can effectively reduce the overall length of the sliding groove 40 in the extending direction, and further reduce the space of the second hinge 32 occupied by the whole sliding groove 40.

Specifically, spout 40 includes first section L1, interlude L2 and the second section L3 that connects gradually, and first section L1 splices with interlude L2 and forms first spout 321, and interlude L2 splices with second section L3 and forms second spout 322.

That is, the slide groove 40 is divided into three sections connected in sequence, and the middle section L2 is an overlapping area of the first slide groove 321 and the second slide groove 322.

In this embodiment, the first sliding slot 321 includes an initial end a1 and a stop end a2 that are opposite to each other, and the second sliding slot 322 includes an initial end B1 and a terminal end B2 that are opposite to each other, when the hinge assembly 30 is at the maximum opening angle, the first shaft body 311 is located at the stop end a2, the stop end a2 is located between the initial end B1 and the terminal end B2 of the second sliding slot 322, that is, the stop end a2 is located in the middle region of the second sliding slot 322.

Of course, in other embodiments, the chute 40 may have other configurations.

Referring to fig. 4, the sliding slot 40 'includes a first sliding slot 321' and a second sliding slot 322 ', which are connected to each other, and there is no overlapping area between the first sliding slot 321' and the second sliding slot 322 ', the first sliding slot 321' includes an initial end a1 and a stop end a2, the second sliding slot 322 'includes an initial end B1 and a terminal end B2, which are opposite to each other, when the hinge assembly 30' is at the maximum opening angle, the first shaft body 311 'is located at the stop end a2, the stop end a2 is located at the boundary area between the first sliding slot 321' and the second sliding slot 322 ', that is, the stop end a2 is located at the end of the second sliding slot 322', and the stop end a2 overlaps the initial end B1.

In the present embodiment, referring to fig. 5 to 13, when the hinge assembly 30 is in the process of being opened from the closed state to the first opening angle α 1, the second hinge member 32 rotates relative to the first hinge member 31 about the first rotation axis P1.

The first rotation axis P1 is a variable axis, and the first rotation axis P1 is a virtual axis.

Here, the phrase "the first rotation axis P1 is a variable axis" means that the first rotation axis P1 is a non-fixed axis.

That is, the position of the first rotating shaft P1 is constantly in the process of changing, that is, the relative position between the first rotating shaft P1 and the cabinet 10 or the door 20 changes.

The phrase "the first rotation axis P1 is a virtual axis" means that the first rotation axis P1 is not substantially present in the hinge assembly 30.

When the hinge assembly 30 is in the process of continuously opening from the first opening angle α 1 to the maximum opening angle α 2, the second hinge member 32 rotates relative to the first hinge member 31 about the second rotation axis P2, and the first rotation axis P1 is different from the second rotation axis P2.

That is, throughout the opening of the hinge assembly 30, the second hinge member 32 is rotated with respect to the first hinge member 31 at the first rotation axis P1 and then rotated with respect to the first hinge member 31 at the second rotation axis P2.

In the present embodiment, the second pivot shaft P2 is a fixed shaft, and the second pivot shaft P2 is a virtual shaft.

Here, the phrase "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 cabinet 10 or the door 20 is fixed.

In other embodiments, the hinge assembly 30 may include only the first rotating shaft P1 or the second rotating shaft P2, and the form of the first rotating shaft P1 and the second rotating shaft P2 is not limited to the above description, that is, the first rotating shaft P1 and the second rotating shaft P2 may be optionally a fixed shaft, a non-fixed shaft, a virtual shaft or a solid shaft (the solid shaft is defined as a component actually included in the hinge assembly 30) according to actual situations.

In the present embodiment, with reference to fig. 5 to 13, when the hinge assembly 30 is in the process of being opened from the closed state to the first opening angle α 1, the second hinge 32 rotates relative to the first hinge 31 around the first rotating shaft P1, and the first shaft 311 and the second shaft 312 slide in the sliding slot 40 at the same time to drive the door 20 to move in the sliding direction relative to the box 10.

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

Here, the "door 20 generates a translation amount with respect to the refrigerator body 10" means that the door 20 simultaneously has a translation amount in the process of rotating with respect to the refrigerator body 10, and when corresponding to a refrigerator, the translation amount means a horizontal movement amount, that is, the door 20 generates a movement amount in a horizontal direction with respect to the refrigerator body 10 in addition to the rotation of the door 20 with respect to the refrigerator body 10.

Next, various specific examples of the movement locus of the door body 20 will be described.

That is, the door 20 rotates in situ by a certain angle and then moves a certain distance in the direction away from the cabinet 200, so as to prevent the door 20 from interfering with the cabinet 200 during the initial opening process.

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

It should be noted that, in this specific example, the first opening angle α 1 is the maximum opening angle, the first shaft 311B moves from the initial end a1 to the stop end a2 to drive the second shaft 312B to move from the initial end B1 to the final end B2, the stop end a2 is overlapped with the initial end B1, and the door 20 rotates in place first and then moves from the pivot side P toward the accommodating chamber D.
