The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

In each drawing of the present invention, for convenience of illustration, some dimensions of structures or parts are exaggerated relative to other structures or parts, and therefore, are only used to illustrate the basic structure of the subject matter of the present invention.

Referring to FIG. 1 , it is a schematic diagram of a household electrical appliance 100 according to an embodiment of the present invention.

The household electrical appliance 100 includes a box body 10 , a door body 20 and a hinge assembly 30 connecting the box body 10 and the door body 20 .

It should be noted that the household electrical appliance 100 may be a refrigerator, a freezer, a wine cabinet, etc. Here, the household electrical appliance 100 is a refrigerator as an example.

In addition, the hinge assembly 30 is not only applicable to the home appliance 100, but also applicable to other scenarios, such as cabinets, wardrobes, etc. The present invention uses the hinge assembly 30 applied to the refrigerator 100 as an example for illustration, but not limited thereto.

Referring to FIG. 2 to FIG. 4 , it is a schematic diagram of a hinge assembly 30 with multiple grooves according to an embodiment of the present invention.

The hinge assembly 30 includes a first hinge part 31 connected to the box body 10 , a second hinge part 32 connected to the door body 20 , and a sliding piece 40 connected to the first hinge part 31 and the second hinge part 32 .

Here, "the first hinge 31 connected to the box 10" means that the first hinge 31 is connected to the box 10, and the first hinge 31 can be an independent part installed on the box 10, or can be directly integrally formed on the box. Parts on the body 10.

Similarly, "the second hinge part 32 connected to the door body 20" means that the second hinge part 32 is connected to the door body 20, and the second hinge part 32 can be an independent part installed on the door body 20, or can be integrally formed directly on the door body 20. Parts on the door body 20.

The hinge assembly 30 also includes two shafts 311, 312 on the first hinge 31, two grooves 401, 402 on the slide 40, a stop protrusion 322 on the second hinge 32, and a stopper 322 on the slide 40. and the rotating assembly 50 between the second hinge member 32 .

Here, "the two shafts 311, 312 located on the first hinge 31" means that the two shafts 311, 312 are arranged on the first hinge 31, and the connection between the two shafts 311, 312 and the first hinge 31 The space may be integrally formed or assembled together. For the explanation of "located" in other parts of the present invention, reference may be made here, and details will not be repeated hereafter.

One of the shafts 312 includes a sliding slot 314, the shaft 312 passes through one of the slots 402 and extends to the second hinge 32, the limiting protrusion 322 is limited to the sliding slot 314, and the center of the shaft 312 when rotating The shaft does not coincide with the central axis of the rotating assembly 50 when rotating, and the other shaft body 311 extends into the other slot body 401 , and the other shaft body 311 is located on a side of the second hinge member 32 close to the sliding piece 40 .

Here, the limiting protrusion 322 is a strip-shaped structure, and the limiting protrusion 322 can slide in the slide groove 314 to drive the relative movement between the second hinge member 32 and the shaft body 312 .

In addition, "the other shaft 311 is located on the side of the second hinge 32 close to the sliding piece 40" means that the shaft 311 does not extend to the inside of the second hinge 32, that is, the end of the shaft 311 near the second hinge 32 The part is located above the second hinge part 32 (that is, the side of the second hinge part 32 close to the sliding plate 40), and the shaft body 311 is not connected to the second hinge part 32 itself, but the shaft body 311 can also be realized by other structures. The connection with the second hinge member 32 is, for example, through the protruding portion 326 and the slideway 404 described later.

When the hinge assembly 30 is in the process of opening, one of the shafts 312 moves relative to one of the grooves 402 and the limit protrusion 322 and the other shaft 311 moves relative to the other groove 401 to drive the second hinge 32 Together with the sliding piece 40 , it moves relative to the first hinge member 31 until the shafts 311 , 312 are limited to the grooves 401 , 402 , and then the rotating assembly 50 drives the second hinge member 32 to move relative to the sliding piece 40 .

Here, the extending direction of the limiting protrusion 322 is consistent with the extending direction of the groove body 402, that is to say, the extending direction of the limiting protrusion 322 is roughly the extending direction of the center line of the groove body 402, when the hinge assembly 30 is in the closed state , in the stacking direction of the first hinge 31 , the sliding piece 40 and the second hinge 32 , the stop protrusion 322 is roughly coincident with the center line of the groove 402 , so that when the shaft 312 slides in the groove 402 , The shaft body 312 can slide relative to the limiting protrusion 322 at the same time, and there is no relative movement between the limiting protrusion 322 and the groove body 402 during the sliding process, so that the second hinge member 32 and the sliding piece 40 remain relatively stationary .

It can be seen that the shaft body 312 is limited in the groove body 402 and the stop protrusion 322 at the same time, and the central axis when the shaft body 312 rotates does not coincide with the central axis when the rotating assembly 50 rotates, so that when the shaft body 312 is in the groove When moving inside the body 402 , the second hinge member 32 and the sliding piece 40 can remain relatively stationary, that is, the second hinge member 32 and the sliding piece 40 can be controlled to move relative to the first hinge member 31 .

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 acts in one direction to drive the second hinge member 32 to move away from the first hinge member 31. The direction movement of the first hinge member 31 , when the hinge assembly 30 is installed on the refrigerator 100 , the opening process of the hinge assembly 30 corresponds to the opening process of the door body 20 .

In this embodiment, first the second hinge member 32 moves relative to the first hinge member 31 together with the sliding piece 40, and then the rotating assembly 50 drives the second hinge member 32 to move relative to the sliding piece 40. It can be seen that in the hinge assembly 30 During the whole opening process, two kinds of movements are realized. The two movements can realize the change of the position of the rotating shaft, which can effectively control the movement track of the door body, thereby improving the degree of freedom in the opening and closing process of the door body 20 of the refrigerator 100, especially the embedded In the field of refrigerators, the door body 20 can be prevented from interfering with surrounding cabinets or walls during the opening and closing process by switching the rotation axis.

In this embodiment, the hinge assembly 30 includes a first shaft body 311 and a second shaft body 312 disposed on the first hinge member 31 , and a first groove body 401 and a second groove body 402 disposed on the sliding piece 40 . A groove body 401 cooperates with the first shaft body 311 , and a second groove body 402 cooperates with the second shaft body 312 .

Here, the second shaft body 312 extends to the overlapping limiting protrusion 322 and the second groove body 402 , and the first shaft body 311 only extends to the first groove body 401 as an example for illustration.

In this embodiment, 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 and the sliding piece 40 are relative to the first hinge member 31 with the first rotation axis P1 as the central axis. Rotation, when the hinge assembly 30 is in the process of continuing to open from the first opening angle α1 to the second opening angle α2, the second hinge member 32 rotates relative to the sliding plate 40 with the second rotation axis P2 as the central axis, and the second rotation axis P2 and the first rotation axis P1 are mutually staggered, that is, the position of the second rotation axis P2 is not consistent with the position of the first rotation axis P1.

Here, the first rotation axis P1 may be a virtual axis or a physical axis.

A virtual shaft refers to a shaft that does not actually exist in the hinge assembly 30 , and a real shaft refers to components actually included in the hinge assembly 30 .

In addition, the first rotation axis P1 may be a non-fixed axis or a fixed axis.

The non-fixed axis means that the position of the first rotation axis P1 is always changing, that is, the relative position between the first rotation axis P1 and the box body 10 or the door body 20 is changing, while the fixed axis refers to the first rotation axis The position of P1 is fixed, that is, the relative position between the first rotation axis P1 and the box body 10 or the door body 20 is fixed.

Similarly, the second rotation axis P2 can be a virtual axis or a physical axis, and the second rotation axis P2 can be a non-fixed axis or a fixed axis, and the second rotation axis P2 and the first rotation axis P1 are mutually staggered, that is, the second rotation axis The position of P2 does not coincide with the position of the first rotation axis P1.

It can be seen that the hinge assembly 30 of this embodiment can effectively control the sequence of the two rotations. During the two rotations, there is a change in the position of the rotation axis, which can effectively control the movement track of the door body 20, thereby improving the door body 20 of the refrigerator 100. The degree of freedom in the opening and closing process, especially in the field of built-in refrigerators, can prevent the door body 20 from interfering with surrounding cabinets or walls during the opening and closing process by switching the rotation axis.

In order to further illustrate the movement track of the hinge assembly 30 , a simple schematic diagram of the hinge assembly 30 assembled to the refrigerator 100 and the refrigerator 100 embedded in the cabinet 200 is taken as an example for illustration with reference to FIG. 5 .

The box body 10 includes an opening 102 and a front end surface 103 arranged around the opening 102. The box body 10 also includes an accommodating chamber D and an outer side surface 13 adjacent to the hinge assembly 30 and on the extension of the rotation path of the door body 20. The door body 20 includes a The front wall 21 of the accommodating chamber D and the side wall 22 always sandwiched between the front wall 21 and the accommodating chamber D, a side edge 23 is formed between the front wall 21 and the side wall 22 .

The hinge assembly 30 is configured such that: when the first rotation axis P1 is actuated, there is a first distance between the first rotation axis P1 and the front end surface 103 of the box body 10; when the second rotation axis P2 is actuated, the second rotation There is a second distance between the axis P2 and the front end surface 103 of the box body 10 , and the second distance is greater than the first distance.

In addition, when the first rotation axis P1 is activated, there is a third distance between the first rotation axis P1 and the outer surface 13 of the box body 10; when the second rotation axis P2 is activated, the second rotation axis P2 and the box body There is a fourth distance between the outer surfaces 13 of 10, and the fourth distance is smaller than the third distance.

Here, "the first rotation axis P1 is actuated" means that the first rotation axis P1 is in the working state, that is, at this time, the second hinge member 32 and the sliding plate 40 rotate relative to the first hinge member 31. Similarly, "the second rotation "Axis P2 is active" means that the second rotation axis P2 is in a working state, that is, the second hinge member 32 rotates relative to the sliding piece 40 at this moment.

It should be noted that the above-mentioned distance refers to the distance between the first rotation axis P1 and the second rotation axis P2 at the position and the front end surface 103 and the outer surface 13 of the box body 10 when the hinge assembly 30 moves to a certain position. , not the distance in the closed state.

The specific instructions are as follows:

In actual operation, in order to improve the embedding effect, it is preferable to completely embed the refrigerator 100 into the cabinet 200. The refrigerator 100 is a free embedded refrigerator, that is, the front end 201 of the cabinet 200 and the front wall 21 of the door 20 are away from the side of the cabinet 10. Located on the same plane, or the front wall 21 of the door body 20 does not protrude from the front end 201 of the cabinet 200 at all.

In the prior art, all refrigerators are single-axis refrigerators, and a certain distance needs to be kept between the rotation axis of the refrigerator and the side wall and front wall of the refrigerator, so that there is enough space for foaming or other processes, that is, the existing The position of the rotation axis of the refrigerator is roughly located at the position of the uniaxial shaft body P3 in FIG. 203 is set corresponding to the side edge 23 of the door body 20. When the door body 20 is opened, the side edge 23 will interfere with the door body 20 to limit the maximum opening angle of the door body 20. In order to ensure the normal opening of the door body 20, the prior art A common practice is to increase the distance between the inner wall 202 of the cabinet 200 and the refrigerator 100, which needs to be about 10 cm, which will seriously affect the embedding effect and is not conducive to the rational use of limited space.

In conjunction with FIG. 5 , the shaded area represents the door body 20 in the closed state. When the door body 20 is in the process of opening, if the door body 20 always rotates around the uniaxial shaft body P3 (that is, the prior art), refer to FIG. 5 The dotted line door body 20' in the figure, because the uniaxial shaft body P3 is close to the front end surface 103, that is, the uniaxial shaft body P3 is far away from the front end 201 of the cabinet 200 at this time, when the door body 20' is opened to a certain angle, the corners 203 of the cabinet 200 It will interfere with the door body 20' to limit the maximum opening angle of the door body 20'.

However, in this embodiment, the door body 20 first rotates with the first rotation axis P1 as the central axis. Specifically, the second hinge member 32 and the sliding piece 40 rotate at a certain angle relative to the first hinge member 31 together. 32. As the position of the sliding piece 40 changes, the relative position of the second rotation axis P2 to the box body 10 also changes, and the second rotation axis P2 gradually moves away from the front end surface 103, that is, the second rotation axis P2 gradually approaches the front end of the cabinet 200 201, at this time, the door body 20 rotates with the second rotation axis P2 at the current position as the central axis, because the second rotation axis P2 at this time is farther away from the front end surface 103 of the box body 10 than the first rotation axis P1 , referring to the solid line door body 20 in Figure 5, the interference effect of the corners 203 of the cabinet 200 on the door body 20 is greatly reduced, and the corners 203 of the cabinet 200 will interfere with each other when the door body 20 is opened to a relatively large angle, thereby greatly improving the door body. The maximum opening angle of the body 20.

That is to say, in this embodiment, the door body 20 is opened to a certain angle and then switched to rotate around the second rotation axis P2, which can effectively increase the maximum opening angle of the door body 20 under the premise of ensuring that the refrigerator 100 is freely embedded in the cabinet 200 , thereby facilitating the user to operate the refrigerator 100, which can greatly improve user experience.

Moreover, in this embodiment, there is no need to increase the distance between the inner wall 202 of the cabinet 200 and the refrigerator 100, and the seamless connection between the refrigerator 100 and the cabinet 200 can be achieved, which greatly improves the embedding effect.

In addition, while the second rotation axis P2 of this embodiment gradually moves toward the front end 201 of the cabinet 200, it also gradually moves closer to the inner wall 202 of the cabinet 200. When the central axis rotates, the second rotation axis P2 is closer to the front end 201 and the inner wall 202 of the cabinet 200 than the first rotation axis P1 at this time. In this way, the maximum opening angle of the door body 20 can be increased, and the door can be opened more easily. The body 20 is away from the box body 10 to increase the opening of the box body 10, which facilitates the opening and closing of shelves, drawers, etc. in the box body 10, or in other words, can facilitate the picking and placing of articles.

Certainly, the second rotation axis P2 finally serving as the central axis can also be located at other positions. The rotation axis P1 is close to the front end 201 of the cabinet 200 , and the second rotation axis P2 is farther away from the inner wall 202 of the cabinet 200 than the first rotation axis P1 and so on.

It can be understood that the slide 40 controls the switching sequence of the first hinge 31 and the second hinge 32 during the opening and closing of the door 20 , which can effectively prevent the door 20 from interfering with the cabinet 200 during opening and closing.

In this embodiment, referring to FIG. 2 to FIG. 5 , the second shaft body 312 includes two second protrusions 3121 , and the two second protrusions 3121 cooperate to form the second slide groove 314 .

Here, the second protrusion 3121 is a cylindrical protrusion.

In this way, when the second chute 314 moves relative to the second protrusion 322, essentially the two second protruding columns 3121 are located on both sides of the second protrusion 322 and slide relative to the second protrusion 322, which can reduce the second The frictional force between the sliding groove 314 and the second protrusion 322 prevents the second sliding groove 314 from being stuck with the second protrusion 322 during the sliding process and cannot continue to move relative to each other.

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

Here, the second shaft body 3122 cooperates with the second groove body 402, and the diameter of the second shaft body body 3122 matches the opening width of the second groove body 402, so that the second shaft body 312 and the second groove body 402 can be avoided. shaking each other.

Of course, in other embodiments, referring to FIG. 6 , the two second protrusions 3121 can be directly connected to the first hinge member 31 .

In this embodiment, the hinge assembly 30 further includes an extension portion 324 connected to the limiting protrusion 322 , and when the second hinge member 32 moves relative to the sliding piece 40 , the second sliding groove 314 slides relative to the extension portion 324 .

The extension portion 324 is an arc protrusion, and the central axis of the arc protrusion is the second rotation axis P2.

Here, the second hinge member 32 and the sliding piece 40 are actually matched by two parts, one part is the connection of the rotating assembly 50, and the other part is the second groove body 402 and the stop protrusion 322 that cooperate with each other, wherein Since the central axis of the second shaft body 312 when rotating relative to the stop protrusion 322 is the first rotating axis P1, and the central axis when the rotating assembly 50 is rotating is the second rotating axis P2, the second hinge member 32 cannot be positioned at the same time. Inconsistent rotation of the first rotation axis P1 and the second rotation axis P2 means that when the second shaft body 312 slides on the position-limiting protrusion 322 , the rotation assembly 50 cannot drive the second hinge member 32 to rotate relative to the sliding plate 40 . That is to say, at this moment, the second hinge member 32 and the sliding piece 40 are relatively stationary.

Specifically, when the hinge assembly 30 is in the process of opening from the closed state to the first opening angle α1, the second shaft body 312 passes through the second sliding groove 314 and is limited to the limit protrusion 322, because the second shaft body 312 Due to the limiting effect of the position-limiting protrusion 322, the second hinge member 32 cannot rotate relative to the sliding piece 40 with the second rotation axis P2 as the central axis, that is, the second hinge member 32 and the sliding piece 40 are relatively stationary. The movement of the shaft body 312 at the second groove body 402 and the stop protrusion 322, the second hinge member 32 and the sliding plate 40 can rotate relative to the first hinge member 31 together until the first shaft body 311 is limited in the first groove body 401 and/or the second shaft body 312 is limited in the second groove body 402 , at this time, the slide piece 40 cannot continue to rotate relative to the first hinge piece 31 , and the first hinge piece 31 and the slide piece 40 are locked to each other.

Then, when the hinge assembly 30 is in the process of continuing to open from the first opening angle α1 to the second opening angle α2, since the hinge assembly 30 also has an extension 324 connected to the stop protrusion 322, the second shaft body 312 can The second rotation axis P2 is the central axis and moves at the extension part 324, which can drive the second hinge member 32 to rotate relative to the sliding piece 40. The body 311 does not hinder the rotation of the second hinge member 32 relative to the sliding piece 40 .

It can be understood that, in other embodiments, other structures may also be added to realize that the second hinge member 32 and the sliding piece 40 remain relatively stationary during the process of opening from the closed state to the first opening angle α1.

In addition, in this embodiment, through the cooperation of the second shaft body 312 and the rotating assembly 50, the mutual locking between the second hinge member 32 and the sliding piece can be realized. At this time, the structure of the second hinge member 32 can be simplified, and further realize Miniaturization of the overall structure of the hinge assembly 30 .

In this embodiment, the second rotation axis P2 is a fixed axis, and the second hinge member 32 rotates relative to the sliding piece 40 around the second rotation axis P2 as a central axis.

The second rotation axis P2 can be a virtual axis or a physical axis, which can be determined according to actual conditions.

In this embodiment, continuing to refer to FIG. 2 to FIG. 5 , the rotating assembly 50 includes a third shaft 403 and a circular hole 325 located between the sliding plate 40 and the second hinge 32, and the third shaft 403 serves as the second rotating The shaft P2 rotates in the circular hole 325 .

In addition, the rotating assembly 50 further includes a protruding portion 326 and a sliding track 404 located between the sliding piece 40 and the second hinge member 32 , and the protruding portion 326 slides in the sliding track 404 with the second rotating axis P2 as a central axis.

At this time, when the second hinge member 32 rotates relative to the sliding piece 40, the third shaft body 403 rotates in situ in the circular hole 325, and the protruding part 326 slides in the slideway 404 with the second rotation axis P2 as the central axis. , which can improve the stability of the rotation of the second hinge member 32 relative to the sliding piece 40 .

In addition, when the protruding part 326 slides to the end of the slideway 404 in the slideway 404 (that is, when the protruding part 326 slides to the limit position), the first hinge part 32 cannot continue to rotate relative to the slide plate 40, and can pass through the slideway 404. The length of 404 controls the maximum opening angle of the door body 20, but not limited thereto.

In this embodiment, since the extension part 324 has a poor limiting effect on the second shaft body 312, when the rotating assembly 50 only includes the third shaft body 403 and the round hole 325, there may be a problem between the second hinge member 32 and the sliding hole. In order to avoid the phenomenon that the pieces 40 shake each other, in this embodiment, the rotating assembly 50 is further provided with a protruding part 326 and a slideway 404 , which can assist the second hinge member 32 to rotate relative to the sliding piece 40 stably.
