In the various drawings of the present invention, certain dimensions of structures or portions may be exaggerated relative to other structures or portions for ease of illustration, and thus, are used only to illustrate the basic structure of the subject matter of the present invention.

Fig. 1 is a schematic diagram of a refrigeration apparatus 100 according to an embodiment of the present invention.

The refrigeration apparatus 100 includes a cabinet 10, a door 20, and a hinge assembly 30 connecting the cabinet 10 and the door 20.

The box 10 includes a receiving chamber D and a pivoting side P connected to the hinge assembly 30, the receiving chamber D is a compartment surrounded by the box 10 and receiving articles, and the pivoting side P is a side where the door 20 is hinged to the box 10.

The refrigeration apparatus 100 may be a refrigerator, a freezer, a wine cabinet, etc., and the refrigeration apparatus 100 is taken as the refrigerator as an example.

In addition, the hinge assembly 30 is not only applicable to the refrigeration device 100, but also applicable to other occasions, such as a cabinet, a wardrobe, etc., and the present invention is described by taking the hinge assembly 30 as an example for the refrigerator 100, but not limited thereto.

Referring to fig. 2 to 3, a hinge assembly 30 having a notch according to an embodiment of the present invention is illustrated.

The hinge assembly 30 includes a first hinge member 31 and a second hinge member 32 which are fitted to each other.

Here, one of the first hinge 31 and the second hinge 32 is connected to the case 10, and the other is connected to the door 20.

The hinge member is connected to the cabinet 10 or the door 20, and means that the hinge member is an independent member mounted to the cabinet 10 or the door 20, or the hinge member is directly and integrally formed with the cabinet 10 or the door 20.

In the present embodiment, the first hinge 31 is connected to the cabinet 10, and the second hinge 32 is connected to the door 20.

One side of the second hinge part 32 close to the door body 20 is provided with a positioning part 33, and the second hinge part 32 is matched with the door body 20 through the positioning part 33.

The first hinge member 31 includes recesses 313 and 314, the second hinge member 32 includes protrusions 321 and 322, and the recesses 313 and 314 slide along the extending direction of the protrusions 321 and 322 to allow the second hinge member 32 to move relative to the first hinge member 31.

Here, the protrusions 321 and 322 are long, and the recesses 313 and 314 are sleeved outside the protrusions 321 and 322 and slide along the extending direction of the protrusions 321 and 322.

That is to say, the first hinge element 31 and the second hinge element 32 realize relative movement therebetween by the mutual cooperation of the notches 313 and 314 and the protrusions 321 and 322, wherein the protrusions 321 and 322 are embedded in the notches 313 and 314, the protrusions 321 and 322 are elongated rib structures, and the notches 313 and 314 are sleeved outside the protrusions 321 and 322 and slide along the extending direction of the protrusions 321 and 322.

In this embodiment, the hinge assembly 30 further includes a first shaft 311 and a second shaft 312 on the first hinge member 31, and a first protrusion 321 and a second protrusion 322 on the second hinge member 32.

Here, the "first shaft body 311 and the second shaft body 312 located on the first hinge part 31" means that the first shaft body 311 and the second shaft body 312 are disposed on the first hinge part 31, and the first shaft body 311, the second shaft body 312 and the first hinge part 31 may be integrally formed or may be assembled into a whole with each other.

The first shaft 311 includes a first notch 313 engaged with the first protrusion 321, and the second shaft 312 includes a second notch 314 engaged with the second protrusion 322, when the hinge assembly 30 is in an opening process, the first notch 313 slides along the first protrusion 321 and the second notch 314 slides along the second protrusion 322 to drive the door 20 to move in a translational amount relative to the box 10.

It should be noted that "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 acted in one 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.

In addition, 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.

It can be understood that the hinge assembly 30 of the present embodiment includes two shafts and two protrusions, and the motion trajectory of the door 20 can be changed to adapt to different application scenarios compared to a single-shaft hinge assembly.

In the present embodiment, the first protrusion 321 and the second protrusion 322 are both long, the first recess 313 is sleeved outside the first protrusion 321 and slides along the extending direction of the first protrusion 321, and the second recess 314 is sleeved outside the second protrusion 322 and slides along the extending direction of the second protrusion 322.

Here, the opening width of the first recess 313 is substantially the same as the width of the first protrusion 321, so that when the first recess 313 slides on the first protrusion 321, the first recess 313 can stably slide along the extending direction of the first protrusion 321 without shaking or jumping, and the length of the first recess 313 in the extending direction of the first protrusion 321 is small, thereby preventing the first recess 313 from interfering with the first protrusion 321 during the sliding process.

Similarly, the opening width of the second recess 314 is substantially the same as the width of the second protrusion 322, so that when the second recess 314 slides on the second protrusion 322, the second recess 314 can stably slide along the extending direction of the second protrusion 322 without shaking or jumping, and the length of the second recess 314 in the extending direction of the second protrusion 322 is small, thereby preventing the second recess 314 from interfering with the second protrusion 322 during the sliding process.

In the present embodiment, the relative movement between the first recess 313 and the first projection 321 includes a reciprocating movement.

Here, the first protrusion 321 includes a first end and a second end that are oppositely disposed, and the "reciprocating motion" refers to that the sliding track of the first recess 313 relative to the first protrusion 321 includes both the sliding track of the first end toward the second end and the sliding track of the second end toward the first end, and the arrangement of the reciprocating motion can effectively shorten the overall length of the first protrusion 321, thereby reducing the size of the whole hinge assembly 30.

Of course, in other embodiments, the relative movement between the first recess 313 and the first protrusion 321 may be only movement in one direction.

In this embodiment, the first protrusion 321 and the second protrusion 322 are disposed at an interval, but not limited thereto, the first protrusion 321 and the second protrusion 322 may also be a continuous elongated protrusion.

The ends of the first protrusion 321 and the second protrusion 322 are provided with a stop portion to prevent the first recess 313 and the second recess 314 from separating from the first protrusion 321 and the second protrusion 322 during the sliding process.

Here, the stopping portion may be a protruding structure disposed at the end portions of the first protrusion 321 and the second protrusion 322, or the end portions of the first protrusion 321 and the second protrusion 322 are bent to limit the first recess 313 and the second recess 314 from sliding continuously, but not limited thereto.

In this embodiment, referring to fig. 3, the first shaft 311 includes two first protruding pillars 3111, the two first protruding pillars 3111 cooperate to form the first recess 313, the second shaft 312 includes two second protruding pillars 3121, and the two second protruding pillars 3121 cooperate to form the second recess 314.

Here, the first boss 3111 and the second boss 3121 are both cylindrical.

Thus, when the first recess 313 moves relative to the first protrusion 321, the two first protruding pillars 3111 are substantially respectively located at two sides of the first protrusion 321 and slide relative to the first protrusion 321, so as to reduce the friction between the first recess 313 and the first protrusion 321, and avoid the first recess 313 and the first protrusion 321 from being stuck to each other during the sliding process and being unable to move continuously.

Similarly, when the second recess 314 moves relative to the second protrusion 322, the two second protruding columns 3121 are respectively located at two sides of the second protrusion 322 and slide relative to the second protrusion 322, so as to reduce the friction force between the second recess 314 and the second protrusion 322, and prevent the second recess 314 and the second protrusion 322 from being jammed and unable to continue to move relative to each other in the sliding process.

In this embodiment, the first shaft 311 further includes a first shaft body 3112 connected to the first hinge member 31, the second shaft 312 further includes a second shaft body 3122 connected to the first hinge member 31, two first protruding columns 3111 are located on a side of the first shaft body 3112 away from the first hinge member 31, and two second protruding columns 3121 are located on a side of the second shaft body 3122 away from the first hinge member 31.

Of course, in other embodiments, the two first posts 3111 and the two second posts 3121 may be directly connected to the first hinge member 31.

In the present embodiment, the second hinge unit 32 rotates relative to the first hinge unit 31 about a first rotation axis as a central axis, the first rotation axis being a variable axis and the first rotation axis being a virtual axis.

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

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

In addition, the "first rotation axis is a virtual axis" means that the first rotation axis is an axis body that is not substantially present in the hinge assembly 30.

Of course, in other embodiments, the first rotating shaft may be a fixed shaft or a solid shaft.

The fixed shaft means that the position of the first rotating shaft is fixed, that is, the relative position between the first rotating shaft and the cabinet 10 or the door 20 is fixed.

A physical axis refers to the component that the hinge assembly 30 actually contains.

In the present embodiment, when the hinge assembly 30 is in the opening process, the door body 20 moves from the pivot side P toward the accommodation chamber D.

Here, when the cabinet is disposed beside the refrigerator, the door 20 moves from the pivoting side P toward the receiving chamber D, that is, the door 20 moves a certain distance in a direction away from the cabinet, so as to prevent the door 20 from interfering with the cabinet during opening.

Specifically, the first protrusion 321 includes an initial position A1 and a first stop position A2, the second protrusion 322 includes a second segment L2, when the hinge assembly 30 is in the process of opening from the closed state to the first opening angle α 1, the second protrusion 322 slides along the second segment L2, the first notch 313 moves from the initial position A1 to the first stop position A2, and the door 20 moves from the pivot side P toward the accommodating chamber D.

Here, the door body 20 includes a front wall 21 distant from the accommodating chamber D and a side wall 22 interposed between the front wall 21 and the accommodating chamber D all the time, and when the second hinge member 32 is connected to the door body 20, the initial position A1 is distant from the front wall 21 and the side wall 22 as compared to the first stop position A2.

Next, a movement locus of a specific example of the refrigerator is described.

The first projection 321 includes an initial position A1, a second stop position A3, a first stop position A2, and a third stop position A4, which are arranged in this order along the extending direction of the first projection 321.

The second protrusion 322 includes a first section L1, a second section L2, a third section L3, and a fourth section L4 connected in sequence along the extending direction of the second protrusion 322.

Referring to fig. 4 to 6, when the hinge assembly 30 is in the closed state, the first notch 313 is located at the initial position A1, and the second notch 314 is located at an end of the first segment L1 away from the second segment L2.

Referring to fig. 7 to 9, when the hinge assembly 30 is opened from the closed state to the first intermediate opening angle α 11, the first notch 313 is maintained at the initial position A1 and the second notch 314 slides along the first segment L1, and the door body 20 rotates in place.

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.

Referring to fig. 10 to 12, when the hinge assembly 30 is in the process of continuously opening from the first intermediate opening angle α 11 to the first opening angle α 1, the second notch 314 slides along the second segment L2 and the first notch 313 moves from the initial position A1 to the first stop position A2, and the door body 20 moves from the pivot side P toward the accommodating chamber D.

Thus, the door 20 can be prevented from interfering with the surrounding cabinets.

Referring to fig. 13 to 15, when the hinge assembly 30 is in the process of continuously opening from the first opening angle α 1 to the second opening angle α 2, the second notch 314 slides along the third section L3, the first notch 313 moves from the first stop position A2 to the second stop position A3, and the door body 20 moves from the accommodating chamber D toward the pivoting side P.

Thus, the door 20 is far away from the box 10 to increase the opening of the box 10, which facilitates the opening and closing of the racks, drawers, etc. in the box 10, or facilitates the taking and placing of the articles.

Referring to fig. 16 to 18, when the hinge assembly 30 is in the process of continuously opening from the second opening angle α 2 to the maximum opening angle α 3, the second notch 314 slides along the fourth segment L4 and the first notch 313 moves from the second stop position A3 to the third stop position A4, and the door body 20 moves from the pivot side P toward the accommodating chamber D.

Here, the second opening angle α 2 substantially corresponds to the opening angle of the door 20 being 90 °, and when the door 20 continues to open, the front wall 21 of the door 20 easily interferes with the peripheral cabinet, and in this case, the door 20 moves from the pivot side P toward the accommodating chamber D, so that the distance between the front wall 21 and the peripheral cabinet may be increased, and the maximum opening angle that can be achieved by the door 20 may be increased.

It can be seen that in the present embodiment, the motion trajectory of the first notch 313 includes a reciprocating motion, while the motion trajectory of the second notch 314 is in the same direction, and the motion trajectory of the refrigerator door 20 corresponding to this example is a home rotation, a simultaneous rotation and a movement from the pivoting side P toward the accommodating chamber D, a simultaneous rotation and a movement from the accommodating chamber D toward the pivoting side P, and a simultaneous rotation and a movement from the pivoting side P continuing toward the accommodating chamber D.

It is understood that in other examples, the motion trajectory of the refrigerator door 20 may include a portion of the above motion trajectory, or the sequence between the various segments of the trajectory may be interchanged, etc.

The above embodiments are only used to illustrate the technical solutions of the present invention, and not to be limited, and although the present invention has been described in detail with reference to the preferred embodiments, for example, if the technologies in different embodiments can be used in a stacked manner to achieve the corresponding effects, the solution thereof is also within the scope of the present invention. It is understood by those skilled in the art that the technical solution of the present invention can be modified or substituted by equivalents without departing from the spirit and scope of the technical solution of the present invention.
