Here, "the first hinge part 31 provided in the box 10" refers to the first hinge part 31 connected to the box 10. The first hinge part 31 can be an independent component installed to the box 10, or it can be directly integrally formed on the box 10. components on the box 10.

Similarly, "the second hinge part 32 provided on the door body 20" means that the second hinge part 32 is connected to the door body 20. The second hinge part 32 can be an independent component installed to the door body 20, or it can be directly formed in one piece. components on the door body 20.

The switching component 40 is located between the first hinge component 31 and the second hinge component 32. The first hinge component 31 and the switching component 40 can interact with each other, and the second hinge component 32 and the switching component 40 can interact with each other. The switching component The function of 40 is to control the working sequence of the first hinge member 31 and the second hinge member 32.

Specifically, the switching component 40 is movably connected to the first hinge component 31 and the second hinge component 32. When the second hinge component 32 is opened in a direction away from the first hinge component 31, the second hinge component 32 and the switching component 40 together move relative to the first hinge component 31. One hinge member 31 moves, then the switching assembly 40 and the first hinge member 31 are relatively stationary, and the second hinge member 32 moves relative to the switching assembly 40 .

Here, "the second hinge member 32 opens in a direction away from the first hinge member 31" means that the second hinge member 32 is acted on in one direction and drives the second hinge member 32 to move in a direction away from the first hinge member 31, that is, corresponding to The opening process of the hinge assembly 30.

It can be understood that 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, the switching component 40 controls the switching operation between the first hinge component 31 and the second hinge component 32 , that is, the switching component 40 first controls the relative movement of the first hinge component 31 and the switching component 40 , and then controls the second hinge component. 32 moves relative to the switching assembly 40. This embodiment controls the opening and closing process of the door 20 by controlling the first hinge member 31 and the second hinge member 32 to work in turn relative to the switching assembly 40, which can improve the opening and closing process of the door 20 of the refrigerator 100. degree of freedom.

It can be understood that the switching component 40 can realize the switching work between the first hinge member 31 and the second hinge member 32 through mechanical structure or electronic control.

In this embodiment, when the hinge assembly 30 is in the opening process, the switching assembly 40 controls the first hinge member 31 and the second hinge member 32 to work sequentially in the first sequence. When the hinge assembly 30 is in the closing process, the switching assembly 40 controls the first hinge member 31 and the second hinge member 32 to work sequentially in the second order, and the first order is opposite to the second order.

Here, “first order” and “second order” refer to the sequential working order between the first hinge member 31 and the second hinge member 32 .

In this embodiment, the switching assembly 40 can effectively control the working sequence between the first hinge part 31 and the second hinge part 32 to avoid the door being caused by the disorder of the order between the first hinge part 31 and the second hinge part 32. The body 20 interferes with the cabinet during the opening and closing process, and is suitable for the field of built-in refrigerators.

In this embodiment, when the door 20 is in the opening process, at least part of the hinge assembly 30 moves relative to the box 10 and the door 20 .

Here, “at least part of the hinge assembly 30 moves relative to the box 10 and the door 20 ” means that at least part of the hinge assembly 30 moves relative to the box 10 and the door 20 at the same time, that is, at least part of the hinge assembly 30 is sandwiched between the box 10 and the door body 20 instead of being completely embedded in the box body 10 or the door body 20 .

Generally, in the existing refrigerator structure, the hinge assembly is usually embedded in the box and the door, that is, the hinge assembly is relatively stationary relative to the box or door. In this way, the movement trajectory of the door 20 will be greatly affected. limit.

In this embodiment, at least part of the hinge assembly 30 moves relative to the box 10 and the door 20 , which can effectively increase the degree of freedom in the opening and closing process of the door 20 , and can effectively control the movement trajectory of the door 20 to adapt to various refrigerators 100 . application scenarios.

In this embodiment, the first hinge member 31 and the switching assembly 40 are connected through the first shaft groups 311 and 312 and the first slot groups 411 and 412 that cooperate with each other. are connected through the mutually matched second shaft body group 321, 322 and the second groove body group 421, 422. The hinge assembly 40 also includes a locking portion. When the second hinge member 32 is opened in the direction away from the first hinge member 31 , the locking part locks the second hinge member 32 so that the second hinge member 32 and the switching assembly 40 move relative to the first hinge member 31, and the first shaft group 311, 312 moves in the first groove group 411, 412 , then the locking part locks the first hinge part 31 and unlocks the second hinge part 32, the switching component 40 and the first hinge part 31 are relatively stationary, the second hinge part 32 moves relative to the switching component 40, the second shaft group 321, 322 moves in the second tank group 421, 422.

That is to say, in this embodiment, the first hinge part 31 , the second hinge part 32 and the switching component 40 are connected through shafts and slots to realize relative movement, and cooperate with the locking part to realize the first hinge part 31 and the second hinge Locking and unlocking of the member 32, in this way, the sequential operation of the first hinge member 31 and the second hinge member 32 can be realized. Of course, in other embodiments, the first hinge member 31, the second hinge member 32 and the switching assembly 40 can also be matched through other structures.

Specific to the opening process of the refrigerator 100, when the door body 20 is in the process of opening from the closed state to the first opening angle α1, the locking part locks the second hinge member 32, and the second hinge member 32 faces the switching assembly 40 together. The first hinge member 31 moves, and the first shaft body group 311, 312 moves in the first slot body group 411, 412. When the door body 20 is in the process of continuing to open from the first opening angle α1 to the second opening angle α2 , the locking part locks the first hinge part 31 and unlocks the second hinge part 32. When the door body 20 is in the process of continuing to open from the second opening angle α2 to the maximum opening angle α3, the switching component 40 and the first hinge part 31 is relatively stationary, the second hinge member 32 moves relative to the switching component 40, and the second shaft group 321, 322 moves in the second groove group 421, 422.

In this embodiment, the movement trajectory of the door body 20 can be effectively controlled by arranging the switching component 40. In particular, the hinge component 30 of this embodiment is suitable for embedded application scenarios.

4 , a simple schematic diagram in which the hinge assembly 30 is assembled to the refrigerator 100 and the refrigerator 100 is embedded in the cabinet 200 is taken as an example for illustration.

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 a receiving 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 There is a front wall 21 of the accommodation chamber D and a side wall 22 that is always sandwiched between the front wall 21 and the accommodation chamber D. There is a side edge 23 between the front wall 21 and the side wall 22 .

The first shaft group 311, 312 includes the first rotation shaft 311, and the second shaft group 321, 322 includes the second rotation shaft 321. When the second hinge member 32 is opened in the direction away from the first hinge member 31, the second shaft group 321, 322 includes the second rotation shaft 321. The hinge member 32 and the switching assembly 40 rotate about the first rotation axis 311 as the central axis, and then the second hinge member 32 rotates about the second rotation axis 321 as the central axis.

Here, the "rotation axis" is defined as the corresponding central axis during the rotation of the door body 20, that is, the door body 20 rotates around the rotation axis to open. The rotation axis can be a fixed axis during the opening process of the door body 20, or it can be a fixed axis in the door body 20. 20Axes that change during the opening process.

Specific to the opening process of the refrigerator 100, when the door 20 is in the process of being opened from the closed state to the first opening angle α1, the door 20 rotates around the first rotation axis 311 as the central axis. When the angle α2 continues to open to the maximum opening angle α3, the door body 20 rotates around the second rotation axis 321 as an axis.

Here, when the first rotation axis 311 serves as the central axis, there is a first distance between the first rotation axis 311 and the front end surface 103 of the box 10. When the second rotation axis 321 serves as the central axis, the second rotation axis 321 and There is a second distance between the front end surfaces 103 of the box 10, and the second distance is greater than the first distance.

When the first rotation axis 311 serves as the central axis, there is a third distance between the first rotation axis 311 and the outer surface 13 of the box 10 . When the second rotation axis 321 serves as the central axis, the second rotation axis 321 is separated from the outer surface 13 of the box 10 . There is a fourth distance between the outer surfaces 13 of 10 , and the fourth distance is smaller than the third distance.

The specific instructions are as follows:

In some movement trajectories of the refrigerator 100, the first rotation axis 311 and the second rotation axis 321 will move relative to the door body 20, or the hinge assembly 30 also includes other axes that cooperate with the first rotation axis 311 and the second rotation axis 321. , in order to simplify the explanation, it is simply considered that the door body 20 first rotates around the first rotation axis 311 as the axis, and then switches to rotate around the second rotation axis 321 as the axis through the switching component 40 .

In actual operation, in order to improve the embedding effect, it is better 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 door 20 are away from the front wall 21 of the cabinet 10. are 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 existing technology, refrigerators are all single-axis refrigerators, and a certain distance needs to be maintained between the rotating axis of the refrigerator and the side walls and front walls of the refrigerator. In this way, there is enough space to meet foaming or other processes, that is, the existing The rotation axis of the refrigerator is roughly located at the first rotation axis 311 in Figure 4. In this case, after the single-axis refrigerator is embedded in the cabinet 200, the cabinet 200 is sandwiched between the front end 201 and the inner wall 202. 203 is provided correspondingly 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 and limit the maximum opening angle of the door body 20. In order to ensure the normal opening of the door body 20, the existing technology The common practice is to increase the distance between the inner wall 202 of the cabinet 200 and the refrigerator 100. The distance needs to be approximately 10 cm, which will seriously affect the embedding effect and is not conducive to the rational use of limited space.

Referring to Figure 4, the shaded area represents the door 20 in a closed state. When the door 20 is in the opening process, if the door 20 always rotates around the first rotation axis 311 (i.e. the prior art), refer to Figure 4 The dotted line door body 20', because the first rotation axis 311 is close to the front end surface 103, that is, the first axis body 311 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 will It interferes with the door body 20' to limit the maximum opening angle of the door body 20'.

In this embodiment, the second rotating shaft 321 is located on the switching component 40. During the opening process of the door 20, the switching component 40 moves relative to the first hinge member 31 and the second hinge member 32 so that the second rotating shaft 321 gradually moves Far away from the front end surface 103 , that is, the second rotation axis 321 gradually moves in a direction closer to the front end 201 of the cabinet 200 , that is, at this time, the entire door body 20 moves in a direction away from the box body 10 , refer to the solid line door body in Figure 4 20. The interference effect of the edges and corners 203 of the cabinet 200 on the door body 20 is greatly reduced. Only when the door body 20 is opened to a larger angle will the edges and corners 203 of the cabinet 200 interfere with each other, thereby greatly increasing the maximum opening angle of the door body 20.

That is to say, in this embodiment, through the action of the switching assembly 40, the later door body 20 can be rotated around the second rotation axis 321, which can effectively increase the maximum opening of the door body 20 while ensuring that the refrigerator 100 can be freely embedded in the cabinet 200. The angle makes it easier for the user to operate the refrigerator 100, which can greatly improve the user experience.

Moreover, this embodiment does not need to increase the distance between the inner wall 202 of the cabinet 200 and the refrigerator 100, and can achieve a seamless connection between the refrigerator 100 and the cabinet 200, which greatly improves the embedding effect.

In addition, while the switching component 40 of this embodiment drives the second rotating shaft 321 to gradually move toward the front end 201 of the cabinet 200, it also drives the second rotating shaft 321 to gradually move closer to the inner wall 202 of the cabinet 200. That is to say, when When the door body 20 rotates around the second rotation axis 321, the second rotation axis 321 at this time is closer to the front end 201 and the inner wall 202 of the cabinet 200 than the first rotation axis 311. In this way, the door body 20 can be raised The maximum opening angle can also move the door 20 away from the box 10 to increase the opening of the box 10, making it easier to open and close shelves, drawers, etc. in the box 10, or to facilitate the taking and placing of items.

Of course, the second rotation axis 321 that ultimately serves as the rotation axis can also be located at other positions. For example, when the door body 20 rotates with the second rotation axis 321 as the axis, the second rotation axis 321 at this time is smaller than the first rotation axis. The axis 311 is close to the front end 201 of the cabinet 200, and the second rotation axis 321 is farther from the inner wall 202 of the cabinet 200 than the first rotation axis 311, and so on.

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

When the hinge assembly 30 is in the When the first opening angle α1 continues to open to the second opening angle α2, the first slide plate group 401 moves relative to the second slide plate group 402 to lock the first hinge member 31 and unlock the second hinge member 32. When the hinge When the assembly 30 is in the process of continuing to open from the second opening angle α2 to the maximum opening angle α3, the first hinge member 31, the first sliding plate group 401 and the second sliding plate group 402 are relatively stationary, and the second hinge member 32 is relatively switched. The component 40 moves, and the first direction is the stacking direction of the first hinge component 31 , the switching component 40 and the second hinge component 32 .

Here, the first shaft body 311 is located at one of the first hinge member 31 and the switching assembly 40 , and the first groove body 411 is located at the other of the first hinge member 31 and the switching assembly 40 .

The second shaft body 312 is located at one of the first hinge member 31 and the switching assembly 40 , and the second slot body 412 is located at the other of the first hinge member 31 and the switching assembly 40 .

The third shaft body 321 is located at one of the second hinge member 32 and the switching assembly 40 , and the third groove body 421 is located at the other of the second hinge member 32 and the switching assembly 40 .

The fourth shaft body 322 is located at one of the second hinge member 32 and the switching assembly 40 , and the fourth groove body 422 is located at the other of the second hinge member 32 and the switching assembly 40 .

That is to say, the distribution form of the hinge assembly 30 can include a variety of situations, and the details can be determined according to the actual situation. In this embodiment, the first hinge member 31 includes a first shaft body 311 and a second shaft body 312, and the second hinge member 32 includes a third groove body 421 and a fourth groove body 422. The switching component 40 includes a first groove body 411, a second groove body 412, a third shaft body 321 and a fourth shaft body 322, for example.

It can be seen that in this embodiment, the first hinge member 31 and the switching component 40 have a biaxial and double-slot cooperation, and the second hinge member 32 and the switching component 40 have a biaxial and double-slot cooperation. However, this is not the case. This is the limit.

In other embodiments, the matching form of a single shaft and a single groove may also be included. For example, the first shaft body group includes a first shaft body, the first groove body group includes a first groove body that matches the first shaft body, and /Or the second shaft body group includes a third shaft body, and the second groove body group includes a third groove body that matches the third shaft body.

Of course, the cooperation between the first hinge member 31 and the switching component 40 may also be a single-axis single-slot cooperation, and the cooperation between the second hinge member 32 and the switching component 40 may be a bi-axial and double-slot cooperation, or the first The cooperation between the hinge member 31 and the switching component 40 is a biaxial and double-slot cooperation. The cooperation between the second hinge member 32 and the switching component 40 is a single-axis single-slot cooperation. Of course, other numbers of shafts and grooves may also be used. Body coordination form.

In this embodiment, continuing with reference to Figures 5 and 6, the first groove 411 includes a first upper groove 413 located in the first slide group 401 and a first lower groove 414 located in the second slide group 402. The first upper groove body 413 includes a first upper free section 4131 , and the first lower groove body 414 includes a first lower free section 4141 .

The second groove body 412 includes a second upper groove body 415 located in the first slide plate group 401 and a second lower groove body 416 located in the second slide plate group 402. The second upper groove body 415 includes a second upper free section 4151, The second lower groove body 416 includes a second lower free section 4161.

The third groove body 421 includes a third free section 4211.

The fourth groove body 422 includes a fourth free section 4221.

The first groove body group 411, 412 includes locking sections 4132, 4142, 4152, 4162, and the second groove body group 421, 422 includes a limiting section 4222.

The locking sections 4132, 4142, 4152, and 4162 include a first upper locking section 4132 located in the first upper groove body 413, a first lower locking section 4142 located in the first lower groove body 414, and a first lower locking section 4142 located in the second upper groove body 415. The second upper locking section 4152 and the second lower locking section 4162 located in the second lower groove body 416, and the limiting section 4222 includes a fourth limiting section 4222 located in the fourth groove body 422.

The first upper locking section 4132 is connected to the first upper free section 4131, the first lower locking section 4142 is connected to the second lower free section 4141, the second upper locking section 4152 is connected to the second upper free section 4151, and the second lower locking section 4152 is connected to the second upper free section 4151. Section 4162 is connected to the second lower free section 4161.

The first upper locking section 4132 and the first lower locking section 4142 are always staggered from each other, and the second upper locking section 4152 and the second lower locking section 4162 are always staggered from each other.

Here, "always staggered from each other" means that during the opening process of the door body 20, the first upper locking section 4132 and the first lower locking section 4142 will not completely overlap, and the second upper locking section 4152 and the second upper locking section 4152 will not completely overlap each other. The lower locking section 4162 will not be completely overlapped either.

Of course, the arrangement positions and numbers of the locking segments 4132, 4142, 4152, 4162 and the limiting segments 4222 are not limited to the above description. For example, the third groove body 421 may also include the limiting segments 4222, or the first upper The groove body 413 and the first lower groove body 414 do not include locking sections and the like.

In this embodiment, the first sliding plate group 401 is closer to the first hinge member 31 than the second sliding plate group 402, that is, the first hinge member 31, the first sliding plate group 401, the second sliding plate group 402 and the second sliding plate group 402. The two hinge parts 32 are stacked in sequence.

5 and 6 , the hinge assembly 30 also includes a first riveting piece 4111 and a second riveting piece 4121. When the first shaft 311 extends into the first groove 411, the first riveting piece 4111 is located on the second sliding piece. The first shaft body 311 is sleeved below the group 402, thus preventing the first shaft body 311 from being separated from the first groove body 411. Similarly, when the second shaft body 312 extends into the second groove body 412, the second riveting The piece 4121 is located below the second sliding plate group 402 and sleeves the second shaft body 312, thus preventing the second shaft body 312 from being separated from the second groove body 412.

The first sliding plate group 401 and the second sliding plate group 402 are coupled to each other through the fifth shaft body 50 .

Here, the first sliding plate group 401 and the second sliding plate group 402 are provided with a first through hole 4014 and a second through hole 4024, and an independent riveting member serves as the fifth shaft body 50 and passes through the first through hole 4014 and the second through hole 4024. Through hole 4024.

Specifically, the fifth shaft body 50 includes a riveting column 51 and a riveting column gasket. The larger end of the riveting column 51 is located below the second through hole 4024 , and the smaller end of the riveting column 51 extends to the second through hole 4024 . In the through hole 4024 and the first through hole 4014, the riveting column gasket is located above the first through hole 4014 and cooperates with the riveting column 51 to lock the riveting column 51. Of course, other matching forms are also possible.

In this way, the first sliding plate group 401 and the second sliding plate group 402 can be coupled with each other, and the relative movement of the first sliding plate group 401 and the second sliding plate group 402 can be realized, and the first sliding plate group 401 and The second slide groups 402 will not separate from each other.

It should be noted that the first through hole 4014 and the second through hole 4024 match each other with the fifth shaft body 50 , and the first slide plate group 401 rotates in situ relative to the second slide plate group 402 .

In other embodiments, a through hole can be provided on one of the first sliding plate group 401 and the second sliding plate group 402, and the fifth shaft body 50 can be provided on the other one, through the fifth shaft body 50 and the through hole. The cooperation realizes the mutual matching of the first slide group 401 and the second slide group 402, but is not limited to this.

In addition, the first sliding plate group 401 includes a third shaft body 321. The third shaft body 321 extends beyond the second sliding plate group 402 to the third groove body 421. The second sliding plate group 402 includes a fourth shaft body 322. The four-axis body 322 extends to the fourth groove body 422 .

That is to say, the third shaft body 321 and the fourth shaft body 322 of this embodiment are located in different slide plate groups, but this is not a limitation.

Next, the specific working process of the hinge assembly 30 is introduced.

7 to 22 , when the hinge assembly 30 is in the process of opening from the closed state to the first opening angle α1, the first slide group 401 and the second slide group 402 are relatively stationary, and the first upper free section 4131 and The first lower free section 4141 overlaps to form the first free section S1, the second upper free section 4151 and the second lower free section 4161 overlap to form the second free section S2, the first shaft 311 moves in the first free section S1, and the second free section 4151 and the second lower free section 4161 overlap to form the second free section S2. The shaft 312 moves in the second free section S2, and the third shaft 321 and/or the fourth shaft 322 are limited in the limiting section 4222 so that the switching component 40 limits the second hinge member 32.

Here, "the third shaft body 321 and/or the fourth shaft body 322 is limited to the limiting section 4222" means that the third shaft body 321 is limited to the limiting section 4222 (that is, the limiting section 4222 is located in the third groove body 421) The fourth shaft body 322 is not limited in position, or the third shaft body 321 is not limited in position and the fourth shaft body 322 is limited in the limiting section 4222 (that is, the limiting section 4222 is located in the fourth groove body 422), or the third shaft body 322 is not limited in position. The three-axis body 321 and the fourth axis body 322 are both limited in the limiting section 4222 (that is, the limiting section 4222 is located in the third groove body 421 and the fourth groove body 422 at the same time).

Specifically, the fourth shaft body 322 is limited to the fourth limiting section 4222, and the second hinge member 32 is in a locked state.

Here, since the first upper free section 4131 and the first lower free section 4141 always overlap to form the first free section S1, the second upper free section 4151 and the second lower free section 4161 always overlap to form the second free section S2, that is, the first The movement trajectories of the slide group 401 and the second slide group 402 are exactly the same, and the first shaft 311 moves in the first free section S1, and at the same time, the second shaft 312 moves in the second free section S2. During this process The first sliding plate group 401 and the second sliding plate group 402 will never be offset from each other, that is, the first sliding plate group 401 and the second sliding plate group 402 remain relatively stationary, which can prevent the first upper free section 4131 from being separated from the first lower free section. The segments 4141 are misaligned with each other, while preventing the second upper free segment 4151 and the second lower free segment 4161 from being misaligned with each other. This ensures that the first shaft 311 moves smoothly in the first free segment S1, and the second shaft 312 moves smoothly in the second free segment S1. Free segment S2 moves smoothly.

23 to 26 , 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 first slide plate group 401 and the second slide plate group 402 move relative to each other so that the second slide plate group 401 and the second slide plate group 402 move relative to each other. The hinge member 32 is separated from the limiting position of the switching assembly 40, and the first shaft body 311 and/or the second shaft body 312 are limited to the locking sections 4132, 4142, 4152, 4162 so that the switching assembly 40 limits the first hinge member 31.

Here, “the relative movement of the first slide group 401 and the second slide group 402 causes the second hinge member 32 to break away from the limiting position of the switching assembly 40, and the first shaft 311 and/or the second shaft 312 are limited to the lock position. "The stop sections 4132, 4142, 4152, 4162 so that the switching component 40 limits the first hinge member 31" means that the relative movement between the switching component 40 and the second hinge component 32 causes the switching component 40 to move between the second hinge component 32 and the second hinge component 32. There is no mutual restriction, and the relative movement between the switching component 40 and the first hinge member 31 causes the switching component 40 and the first hinge component 31 to restrict each other.

In an example, the first shaft body 311 is limited to the first upper locking section 4132 and the first lower locking section 4142 at the same time, and the second shaft body 312 is limited to the second upper locking section 4152 and the second lower locking section at the same time. Section 4162, and the fourth shaft body 322 is separated from the fourth limiting section 4222. The description is as follows:

When the door body 20 is opened to the first opening angle α1, the second shaft body 312 moves from the second free section S2 to the second lower locking section 4162 and is limited. At this time, the first shaft body 311 and the second shaft body 312 It can no longer move relative to the first free section S1 and the second free section S2, and at this time, the first shaft 311 is adjacent to the first upper locking section 4132 and the first lower locking section 4142, and the second shaft 312 is adjacent to the second The trajectories of the upper locking section 4152 , the first upper locking section 4132 and the second upper locking section 4152 are adapted to the movement paths of the first shaft 311 and the second shaft 312 .

When the door body 20 continues to open based on the first opening angle α1, the door body 20 drives the second hinge member 32 connected to the door body 20 to move, and the second hinge member 32 passes through the third free section 4211 and the fourth limiting section. 4222 to exert force on the third shaft 321 and the fourth shaft 322, and then the third shaft 321 and the fourth shaft 322 drive the first slide group 401 and the second slide group 402 to move.

Specifically, at this time, the first shaft 311 is adjacent to the first upper locking section 4132, the second shaft 312 is adjacent to the second upper locking section 4152, and the first slide group 401 can be relative to the first shaft 311 and the second shaft. The body 312 moves at a first angle until the first shaft 311 is limited to the first upper locking section 4132, and the second shaft 312 is limited to the second upper locking section 4152. At the same time, the second slide group 402 moves to the fifth The shaft body 50 is the center of the circle and moves at a second angle relative to the first shaft body 311 until the first shaft body 311 is limited in the second locking section 4152. During this process, the second shaft body 312 and the second lower locking section 4162 are always in contact, and the second angle is greater than the first angle.

That is to say, both the first slide group 401 and the second slide group 402 will rotate at a certain angle, and the rotation angle of the second slide group 402 is greater than the rotation angle of the first slide group 401. The first slide group 401 Relative motion will also occur between the second slide plate group 402 and the second slide plate group 402 to be staggered from each other.

It can be understood that the rotation process of the first slide group 401 and the second slide group 402 does not have a certain sequence. They can rotate at the same time. For example, the first slide group 401 and the second slide group 402 rotates synchronously within a certain rotation angle range, and then the first slide group 401 and the second slide group 402 are staggered from each other.

In actual operation, the first sliding plate group 401 and the second sliding plate group 402 drive the first groove body 411 and the second groove body 412 to rotate relative to the first shaft body 311 and the second shaft body 312 respectively, and the first shaft body 311 is detached. The first free section S1 is in contact with the first upper locking section 4132 and the first lower locking section 4142, that is, the first shaft 311 is simultaneously limited to the first upper locking section 4132 and the first lower locking section 4142, The second shaft body 312 is separated from the second free section S2 and abuts against the second upper locking section 4152 and the second lower locking section 4162. That is, the second shaft body 312 is simultaneously limited to the second upper locking section 4152 and the second lower locking section 4162. The lower locking section 4162, at the same time, the movement of the second slide group 402 causes the fourth shaft 322 to break away from the fourth limiting section 4222.

It can be understood that when the first shaft 311 is located at the first upper locking section 4132 and the first lower locking section 4142, since the first slide plate group 401 and the second slide plate group 402 are staggered from each other, they are originally mutually exclusive. The overlapping first upper free section 4131 and the first lower free section 4141 will also be staggered from each other. At this time, the mutually staggered first upper free section 4131 and the first lower free section 4141 restrict the first shaft 311 from escaping from the first upper lock. section 4132 and the first lower locking section 4142 to ensure that the first shaft 311 is always maintained at the first upper locking section 4132 and the first lower locking section 4142 when the door body 20 continues to open.

Similarly, when the second shaft 312 is located at the second upper locking section 4152 and the second lower locking section 4162, since the first slide plate group 401 and the second slide plate group 402 are staggered from each other, they originally overlap each other. The second upper free section 4151 and the second lower free section 4161 will also be staggered from each other. At this time, the mutually staggered second upper free section 4151 and the second lower free section 4161 restrict the second shaft 312 from disengaging from the second upper locking section. 4152 and the second lower locking section 4162 to ensure that the second shaft 312 is always maintained at the second upper locking section 4152 and the second lower locking section 4162 when the door body 20 continues to open.

In addition, the rotation angle of the second slide group 402 is greater than the rotation angle of the first slide group 401, that is, the second slide group 402 and the first slide group 401 are staggered from each other, which can further improve the distance between the first hinge member 31 and the first slide group 401. The locking effect between the switching components 40 ensures that the first shaft 311 is always maintained at the first upper locking section 4132 and the first lower locking section 4142, and the second shaft 312 is always kept at the second upper locking section. Section 4152 and the second lower locking section 4162.

27 to 30 , when the hinge assembly 30 continues to open from the second opening angle α2 to the maximum opening angle α3, the third shaft 321 moves in the third free section 4211, and the fourth shaft 322 moves in the fourth free section 4211. Free segment 4221 movement.

It can be seen that in this embodiment, through the unlocking and locking effects of the switching assembly 40 on the first hinge member 31 and the second hinge member 32, the sequential switching of the first hinge member 31 and the second hinge member 32 can be effectively controlled, so that the door can be opened and closed. The body 20 can be opened stably.

It can be understood that when the door body 20 is in the closing process, that is, when the door body 20 starts to close from the maximum opening angle α3, the switching component 40 can also effectively control the sequential switching of the first hinge member 31 and the second hinge member 32, that is, When the door body 20 is in the process of closing from the maximum opening angle α3 to the second opening angle α2, the third shaft 321 moves in the third free section 4211, the fourth shaft 322 moves in the fourth free section 4221, and switches The assembly 40 locks the first hinge member 31. When the door body 20 is in the process of closing from the second opening angle α2 to the first opening angle α1, the first slide plate group 401 and the second slide plate group 402 move relative to each other so that The first hinge member 31 is separated from the limiting position of the switching assembly 40, and the fourth shaft 322 is limited to the fourth limiting section 4222. The switching assembly 40 locks the second hinge member 32. When the door body 20 is at the first opening angle α1 During the process of closing to complete closing, the first shaft 311 moves in the first free section S1, and the second shaft 312 moves in the second free section S2.

In other words, the closing process of the door body 20 and the opening process of the door body 20 are in reverse order. Through the unlocking and locking effects of the switching assembly 40 on the first hinge member 31 and the second hinge member 32, the door can be effectively controlled. The switching sequence of the first hinge part 31 and the second hinge part 32 during the opening and closing process of the body 20.

In addition, in this embodiment, the first shaft body 311 and the third shaft body 321 are staggered from each other.

When the door body 20 is in the process of opening to the first opening angle α1 from the closed state, the door body 20 rotates with the first axis 311 as the central axis. When the door body 20 is in the process of opening from the second opening angle α2 to the maximum opening angle During the process of α3, the door body 20 rotates with the third shaft 321 as the axis.

When the first shaft 311 serves as the central axis, there is a first distance between the first shaft 311 and the front end surface 103 of the box 10 , and there is a third distance between the first shaft 311 and the outer surface 13 of the box 10 , when the third shaft 321 serves as the central axis, there is a second distance between the third shaft 321 and the front end surface 103 of the box 10 , and there is a fourth distance between the third shaft 321 and the outer side 13 of the box 10 . distance, the second distance is greater than the first distance, and the fourth distance is less than the third distance.

Referring to the foregoing description, the hinge assembly 30 of this embodiment may be suitable for use in built-in cabinets or scenarios where the space for accommodating the refrigerator 100 is small.

In addition, it should be noted that the movement trajectory of the door 20 can be effectively controlled through a specific shaft groove design. In this embodiment, the box 10 includes a pivot side P connected to the hinge assembly 30. When the door 20 is in During the opening process, the hinge assembly 30 at least drives the door body 20 to move from the pivot side P toward the accommodation chamber D, thereby preventing the door body 20 from interfering with surrounding cabinets or walls during the opening process. Please refer to the following examples for specific designs.

In an example, the first free section S1 includes an initial position A1 and a stop position A2 that are oppositely arranged, and the second free section S2 includes a first section L1, a second section L2, and a third section L3 that are connected in sequence.

Referring to Figures 7 to 10, when the door 20 is in a closed state, the first shaft 311 is located at the initial position A1, the second shaft 312 is located at an end of the first section L1 away from the second section L2, and the fourth shaft 322 Located at the limiting section 4222, the switching assembly 40 limits the second hinge member 32.

Referring to Figures 11 to 22, when the door 20 is in the process of opening from the closed state to the first opening angle α1, the first shaft 311 rotates in situ at the initial position A1, and the second shaft 312 rotates with the first shaft 311 is the center of the circle and moves in the first section L1. The door 20 rotates in place relative to the box 10. Then the second shaft 312 moves in the second section L2 and drives the first shaft 311 to move from the initial position A1 to stop. At position A2, the door body 20 moves from the pivot side P toward the accommodation chamber D, and then the second shaft body 312 moves in the third section L3 to drive the first shaft body 311 to move from the stop position A2 toward the initial position A1. The door body 20 moves from the accommodation chamber D toward the pivot side P.
