In the present 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 sequentially operate in a first order, and 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 sequentially operate in a second order, the first order being opposite to the second order.
Here, "first order" and "second order" refer to the order of operation between the first hinge member 31 and the second hinge member 32.
The working sequence between the first hinge member 31 and the second hinge member 32 can be effectively controlled by the switching assembly 40, so that the mutual interference between the door body 20 and the cabinet in the opening and closing process caused by the disordered sequence between the first hinge member 31 and the second hinge member 32 is avoided, and the method is suitable for the field of embedded refrigerators.
In this embodiment, at least a portion of the hinge assembly 30 moves relative to the case 10 and the door 20 when the door 20 is in the open process.
Here, "at least part of the hinge assembly 30 moves relative to the case 10 and the door 20" means that at least part of the hinge assembly 30 moves simultaneously relative to the case 10 and the door 20, i.e., at least part of the hinge assembly 30 is sandwiched between the case 10 and the door 20, not completely embedded in the case 10 or the door 20.
Generally, in the conventional refrigerator structure, the hinge assembly is generally embedded in the case and the door, i.e., the hinge assembly is relatively stationary with respect to the case or the door, so that the movement track of the door 20 is greatly limited.
At least a part of the hinge assembly 30 in this embodiment moves relative to the case 10 and the door 20, so that the degree of freedom in the opening and closing process of the door 20 can be effectively improved, and the movement track of the door 20 can be effectively controlled, so as to adapt to various application scenarios of the refrigerator 100.
In this embodiment, the first hinge member 31 is connected to the switching assembly 40 through the first shaft body groups 311 and 312 and the first slot body groups 411 and 412, the second hinge member 32 is connected to the switching assembly 40 through the second shaft body groups 321 and 322 and the second slot body groups 421 and 422, the hinge assembly 40 further includes a locking portion, when the second hinge member 32 is opened in a direction away from the first hinge member 31, the locking portion locks the second hinge member 32 to move the second hinge member 32 and the switching assembly 40 together relative to the first hinge member 31, the first shaft body groups 311 and 312 move in the first slot body groups 411 and 412, and then the locking portion locks the first hinge member 31 and unlocks the second hinge member 32, the switching assembly 40 and the first hinge member 31 are relatively stationary, the second hinge member 32 moves relative to the switching assembly 40, and the second shaft body groups 321 and 322 move in the second slot body groups 421 and 422.
That is, the first hinge member 31, the second hinge member 32 and the switching unit 40 of the present embodiment are connected by the shaft and the groove to perform the relative movement, and the locking and unlocking of the first hinge member 31 and the second hinge member 32 are performed in cooperation with the locking portion, so that the sequential operation of the first hinge member 31 and the second hinge member 32 can be performed, however, in other embodiments, the first hinge member 31, the second hinge member 32 and the switching unit 40 may be engaged with each other by other structures.
Specifically, in 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 portion locks the second hinge member 32, the second hinge member 32 moves together with the switching assembly 40 relative to the first hinge member 31, the first shaft body groups 311 and 312 move in the first slot body groups 411 and 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 portion locks the first hinge member 31 and unlocks the second hinge member 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 assembly 40 and the first hinge member 31 are relatively stationary, the second hinge member 32 moves relative to the switching assembly 40, and the second shaft body groups 321 and 322 move in the second slot body groups 421 and 422.
The motion track of the door body 20 can be effectively controlled by arranging the switching component 40 in the present embodiment, and in particular, the hinge component 30 in the present embodiment is suitable for an embedded application scenario.
Referring to fig. 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.
The case 10 includes an opening 102 and a front end surface 103 surrounding the opening 102, the case 10 further includes a receiving chamber D and an outer side surface 13 adjacent to the hinge assembly 30 and on an extension of a rotation path of the door 20, the door 20 includes a front wall 21 far from the receiving chamber D and a side wall 22 always sandwiched between the front wall 21 and the receiving chamber D, and a side edge 23 is provided between the front wall 21 and the side wall 22.
The first shaft body groups 311 and 312 include a first rotation shaft 311, the second shaft body groups 321 and 322 include a second rotation shaft 321, and when the second hinge member 32 is opened in a direction away from the first hinge member 31, the second hinge member 32 and the switching member 40 rotate about the first rotation shaft 311, and then the second hinge member 32 rotates about the second rotation shaft 321.
Here, the "rotation axis" is defined as a corresponding central axis during the rotation of the door body 20, that is, the door body 20 is rotated and opened around the rotation axis, and the rotation axis may be a fixed axis during the opening of the door body 20 or a variable axis during the opening of the door body 20.
Specifically, to the opening process of the refrigerator 100, when the door 20 is in the process of being opened to the first opening angle α1 in the closed state, the door 20 is rotated about the first rotation shaft 311 as the central axis, and when the door 20 is in the process of being continuously opened to the maximum opening angle α3 from the second opening angle α2, the door 20 is rotated about the second rotation shaft 321 as the central axis.
Here, when the first rotation shaft 311 is the central axis, a first distance is provided between the first rotation shaft 311 and the front end surface 103 of the case 10, and when the second rotation shaft 321 is the central axis, a second distance is provided between the second rotation shaft 321 and the front end surface 103 of the case 10, the second distance being greater than the first distance.
When the first rotation shaft 311 is used as the central axis, a third distance is provided between the first rotation shaft 311 and the outer side 13 of the case 10, and when the second rotation shaft 321 is used as the central axis, a fourth distance is provided between the second rotation shaft 321 and the outer side 13 of the case 10, and the fourth distance is smaller than the third distance.
The concrete explanation is as follows:
in some motion tracks of the refrigerator 100, the first rotation shaft 311 and the second rotation shaft 321 may move relative to the door body 20, or the hinge assembly 30 may further include other shafts cooperating with the first rotation shaft 311 and the second rotation shaft 321, for simplicity, it is simply considered that the door body 20 rotates about the first rotation shaft 311 first and then is switched to rotate about the second rotation shaft 321 by the switching assembly 40.
In practice, in order to enhance the embedding effect, it is preferable that the refrigerator 100 is completely embedded in the cabinet 200, and the refrigerator 100 is a free embedded refrigerator, i.e., the front end 201 of the cabinet 200 is located on the same plane with the front wall 21 of the door 20 on the side far from the cabinet 10, or the front wall 21 of the door 20 does not protrude beyond the front end 201 of the cabinet 200 at all.
In the prior art, the refrigerator is a single-shaft refrigerator, and the rotation axis of the refrigerator needs to keep a certain distance from the side wall and the front wall of the refrigerator, so that enough space is needed to satisfy foaming or other processes, that is, the rotation axis of the existing refrigerator is located at the position of the first rotation axis 311 in fig. 4, in this case, after the single-shaft refrigerator is embedded into the cabinet 200, since the corner 203 of the cabinet 200 clamped between the front end 201 and the inner wall 202 is arranged corresponding to the side edge 23 of the door 20, when the door 20 is opened, the side edge 23 interferes with the door 20 to limit the maximum opening angle of the door 20, and in order to ensure the normal opening of the door 20, the conventional method is to increase the space between the inner wall 202 of the cabinet 200 and the refrigerator 100, which is about 10cm, which seriously affects the embedding effect and is unfavorable for the reasonable utilization of the limited space.
Referring to fig. 4, the hatched area indicates the door 20 in the closed state, when the door 20 is in the open process, if the door 20 is always rotated around the first rotation axis 311 (i.e. the prior art), referring to the dashed door 20 'in fig. 4, since the first rotation axis 311 is close to the front end surface 103, i.e. the first axis 311 is far away from the front end 201 of the cabinet 200, after the door 20' is opened to a certain angle, the edges 203 of the cabinet 200 interfere with the door 20 'to limit the maximum opening angle of the door 20'.
In the present embodiment, the second rotation shaft 321 is located on the switching component 40, and 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 rotation shaft 321 gradually moves away from the front end surface 103, i.e. the second rotation shaft 321 gradually moves towards the direction close to the front end 201 of the cabinet 200, i.e. at this time, the whole door 20 moves towards the direction away from the case 10, referring to the solid line door 20 in fig. 4, the interference effect of the edges 203 of the cabinet 200 on the door 20 is greatly reduced, and the edges 203 of the cabinet 200 interfere with each other when the door 20 is opened to a larger angle, so that the maximum opening angle of the door 20 is greatly improved.
That is, the function of the switching assembly 40 in this embodiment can enable the later door 20 to rotate about the second rotation axis 321, so that the maximum opening angle of the door 20 can be effectively increased on the premise of ensuring that the refrigerator 100 is freely embedded into the cabinet 200, thereby facilitating the user to operate the refrigerator 100 and greatly improving the user experience.
In addition, the interval between the inner wall 202 of the cabinet 200 and the refrigerator 100 is not required to be increased, so that the refrigerator 100 and the cabinet 200 can be connected in a seamless manner, and the embedding effect is greatly improved.
In addition, the switching assembly 40 of the present embodiment drives the second rotation shaft 321 to gradually move towards the direction close to the front end 201 of the cabinet 200, and simultaneously drives the second rotation shaft 321 to gradually approach the inner wall 202 of the cabinet 200, that is, when the door 20 rotates around the second rotation shaft 321, the second rotation shaft 321 is closer to the front end 201 and the inner wall 202 of the cabinet 200 than the first rotation shaft 311, so that the maximum opening angle of the door 20 can be increased, and the door 20 can be further separated from the box 10 to increase the opening of the box 10, thereby facilitating the opening and closing of racks, drawers, and the like in the box 10, or facilitating the picking and placing of objects.
Of course, the second rotation axis 321 as the rotation axis may be located at other positions, for example, when the door 20 rotates around the second rotation axis 321, the second rotation axis 321 is closer to the front end 201 of the cabinet 200 than the first rotation axis 311, and the second rotation axis 321 is farther from the inner wall 202 of the cabinet 200 than the first rotation axis 311.
It can be appreciated that the switching assembly 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, so as to effectively avoid the interference between the door 20 and the cabinet 200 during the opening and closing process.

Of course, the installation positions, the number, etc. of the locking sections 4132, 4142, 4152, 4162 and the limiting sections 4222 are not limited to the above description, for example, the third groove 421 may also include the limiting sections 4222, or the first upper groove 413 and the first lower groove 414 do not include the locking sections, etc.
In the present embodiment, the first slider set 401 is closer to the first hinge member 31 than the second slider set 402, that is, the first hinge member 31, the first slider set 401, the second slider set 402 and the second hinge member 32 are stacked in order.
Referring to fig. 5 and 6, the hinge assembly 30 further includes a first riveting piece 4111 and a second riveting piece 4121, when the first shaft body 311 extends into the first slot body 411, the first riveting piece 4111 is located below the second slide sheet set 402 and is sleeved with the first shaft body 311, so that the first shaft body 311 is prevented from being separated from the first slot body 411, and similarly, when the second shaft body 312 extends into the second slot body 412, the second riveting piece 4121 is located below the second slide sheet set 402 and is sleeved with the second shaft body 312, so that the second shaft body 312 is prevented from being separated from the second slot body 412.
The first sliding vane set 401 and the second sliding vane set 402 are mutually matched and connected through the fifth shaft body 50.
Here, the first slider group 401 and the second slider group 402 are provided with a first through hole 4014 and a second through hole 4024, and independent caulking pieces pass through the first through hole 4014 and the second through hole 4024 as the fifth shaft body 50.
Specifically, the fifth shaft body 50 includes a rivet 51 and a rivet spacer, wherein one end of the rivet 51 having a larger size is located below the second through hole 4024, one end of the rivet 51 having a smaller size extends into the second through hole 4024 and the first through hole 4014 in sequence, and the rivet spacer is located above the first through hole 4014 and cooperates with the rivet 51 to lock the rivet 51, however, other cooperating forms are possible.
Thus, the first sliding vane set 401 and the second sliding vane set 402 can be mutually matched, so that the first sliding vane set 401 and the second sliding vane set 402 can relatively move, and the first sliding vane set 401 and the second sliding vane set 402 can not be mutually separated.
The first through hole 4014 and the second through hole 4024 are matched with the fifth shaft 50, and the first slider set 401 is rotated in place relative to the second slider set 402.
In other embodiments, a through hole may be provided on one of the first sliding vane set 401 and the second sliding vane set 402, and a fifth shaft 50 is provided on the other, so that the first sliding vane set 401 and the second sliding vane set 402 are mutually matched through the cooperation of the fifth shaft 50 and the through hole, but not limited thereto.
In addition, the first slider group 401 includes a third shaft 321, the third shaft 321 extends to the third groove 421 beyond the second slider group 402, the second slider group 402 includes a fourth shaft 322, and the fourth shaft 322 extends to the fourth groove 422.
That is, the third shaft 321 and the fourth shaft 322 of the present embodiment are located in different slide sets, but not limited to this.
Next, a specific working procedure of the hinge assembly 30 will be described.
Referring to fig. 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 sliding vane set 401 and the second sliding vane set 402 are relatively stationary, the first upper free section 4131 and the first lower free section 4141 overlap to form a first free section S1, the second upper free section 4151 and the second lower free section 4161 overlap to form a second free section S2, the first shaft 311 moves in the first free section S1, the second shaft 312 moves in the second free section S2, and the third shaft 321 and/or the fourth shaft 322 are limited by the limiting section 4222, so that the switching assembly 40 limits the second hinge member 32.
Here, the phrase "the third shaft body 321 and/or the fourth shaft body 322 are limited to the limiting section 4222" means that the third shaft body 321 is limited to the limiting section 4222 (i.e., the limiting section 4222 is located in the third groove 421) and the fourth shaft body 322 is not limited, or the third shaft body 321 is not limited to the limiting section 4222 (i.e., the limiting section 4222 is located in the fourth groove 422), or both the third shaft body 321 and the fourth shaft body 322 are limited to the limiting section 4222 (i.e., the limiting section 4222 is located in both the third groove 421 and the fourth groove 422).
Specifically, the fourth shaft body 322 is limited to the fourth limiting segment 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, and 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 movement track of the first sliding vane set 401 and the second sliding vane set 402 are identical, and the first shaft body 311 moves in the first free section S1, and simultaneously, the second shaft body 312 moves in the second free section S2, in this process, the first sliding vane set 401 and the second sliding vane set 402 are not staggered with each other, that is, the first sliding vane set 401 and the second sliding vane set 402 remain relatively stationary, so that the first upper free section 4131 and the first lower free section 4141 are prevented from being dislocated with each other, and meanwhile, the second upper free section 4151 and the second lower free section 4161 are prevented from being dislocated with each other, so that smooth movement of the first shaft body 311 in the first free section S1 and smooth movement of the second shaft body 312 in the second free section S2 can be ensured.
Referring to fig. 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 sliding vane set 401 and the second sliding vane set 402 move relatively to disengage the second hinge member 32 from the limit of the switching assembly 40, and the first shaft body 311 and/or the second shaft body 312 are limited on the locking sections 4132, 4142, 4152, 4162 to enable the switching assembly 40 to limit the first hinge member 31.
Here, "the first sliding vane set 401 and the second sliding vane set 402 move relatively to disengage the second hinge member 32 from the limit of the switching assembly 40, and the first shaft body 311 and/or the second shaft body 312 are limited by the locking sections 4132, 4142, 4152, 4162 to limit the switching assembly 40 to the first hinge member 31" means that the switching assembly 40 and the second hinge member 32 move relatively to each other so that no limit exists between the switching assembly 40 and the second hinge member 32, and the switching assembly 40 and the first hinge member 31 move relatively to each other so that the switching assembly 40 and the first hinge member 31 limit each other.
In an example, the first shaft body 311 is simultaneously located at the first upper locking section 4132 and the first lower locking section 4142, the second shaft body 312 is simultaneously located at the second upper locking section 4152 and the second lower locking section 4162, and the fourth shaft body 322 is separated from the fourth limiting section 4222, which is described as follows:
When the door 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 cannot move relative to the first free section S1 and the second free section S2, and the first shaft body 311 is adjacent to the first upper locking section 4132 and the first lower locking section 4142, the second shaft body 312 is adjacent to the second upper locking section 4152, and the track of the first upper locking section 4132 and the second upper locking section 4152 is adapted to the movement path of the first shaft body 311 and the second shaft body 312.
When the door 20 is opened continuously based on the first opening angle α1, the door 20 drives the second hinge member 32 connected to the door 20 to move, and the second hinge member 32 applies a force to the third shaft 321 and the fourth shaft 322 through the third free section 4211 and the fourth limiting section 4222, so that the third shaft 321 and the fourth shaft 322 drive the first sliding vane set 401 and the second sliding vane set 402 to move.
Specifically, at this time, the first shaft body 311 is adjacent to the first upper locking section 4132, the second shaft body 312 is adjacent to the second upper locking section 4152, the first sliding vane set 401 may move by a first angle relative to the first shaft body 311 and the second shaft body 312 until the first shaft body 311 is limited to the first upper locking section 4132, and the second shaft body 312 is limited to the second upper locking section 4152, and at the same time, the second sliding vane set 402 moves by a second angle relative to the first shaft body 311 with the fifth shaft body 50 as a center of a circle until the first shaft body 311 is limited to the second locking section 4152, and during this process, the second shaft body 312 is always contacted with the second lower locking section 4162, and the second angle is greater than the first angle.
That is, the first sliding vane set 401 and the second sliding vane set 402 rotate by a certain angle, and the rotation angle of the second sliding vane set 402 is larger than that of the first sliding vane set 401, and the first sliding vane set 401 and the second sliding vane set 402 are also relatively moved to be staggered.
It is understood that the rotation process of the first sliding vane set 401 and the second sliding vane set 402 does not have a certain sequence, and the first sliding vane set 401 and the second sliding vane set 402 may rotate simultaneously, for example, the first sliding vane set 401 and the second sliding vane set 402 rotate synchronously within a certain rotation angle range, and then the first sliding vane set 401 and the second sliding vane set 402 are staggered.
In actual operation, the first sliding vane set 401 and the second sliding vane set 402 drive the first slot 411 and the second slot 412 to rotate relative to the first shaft 311 and the second shaft 312, respectively, the first shaft 311 is separated from the first free section S1 and is abutted to the first upper locking section 4132 and the first lower locking section 4142, i.e. the first shaft 311 is simultaneously located at the first upper locking section 4132 and the first lower locking section 4142, the second shaft 312 is separated from the second free section S2 and is abutted to the second upper locking section 4152 and the second lower locking section 4162, i.e. the second shaft 312 is simultaneously located at the second upper locking section 4152 and the second lower locking section 4162, and meanwhile, the movement of the second sliding vane set 402 makes the fourth shaft 322 separate from the fourth limiting section 4222.
It can be appreciated that when the first shaft body 311 is located at the first upper locking section 4132 and the first lower locking section 4142, since the first slide sheet set 401 and the second slide sheet set 402 are staggered, the first upper free section 4131 and the first lower free section 4141 which are originally overlapped with each other are also staggered, and the first upper free section 4131 and the first lower free section 4141 which are staggered with each other limit the first shaft body 311 to separate from the first upper locking section 4132 and the first lower locking section 4142, so that the first shaft body 311 can be ensured to be always kept at the first upper locking section 4132 and the first lower locking section 4142 in the process of continuously opening the door body 20.
Similarly, when the second shaft body 312 is located at the second upper locking section 4152 and the second lower locking section 4162, since the first sliding vane set 401 and the second sliding vane set 402 are staggered, the first upper free section 4151 and the second lower free section 4161 that are originally overlapped with each other are also staggered, and the staggered second upper free section 4151 and second lower free section 4161 limit the second shaft body 312 to separate from the second upper locking section 4152 and the second lower locking section 4162, so as to ensure that the second shaft body 312 is always kept at the second upper locking section 4152 and the second lower locking section 4162 during the continuous opening of the door body 20.
In addition, the rotation angle of the second sliding vane set 402 is greater than that of the first sliding vane set 401, that is, the second sliding vane set 402 and the first sliding vane set 401 are staggered with each other, so that the locking effect between the first hinge member 31 and the switching assembly 40 can be further improved, the first shaft body 311 is ensured to be always kept at the first upper locking section 4132 and the first lower locking section 4142, and the second shaft body 312 is always kept at the second upper locking section 4152 and the second lower locking section 4162.
Referring to fig. 27 to 30, when the hinge assembly 30 is continuously opened 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 4221.
It can be seen that, in this embodiment, through the unlocking and locking actions of the switching component 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 body 20 can be stably opened.
It can be appreciated that when the door 20 is in the closing process, i.e. the door 20 starts to be closed from the maximum opening angle α3, the switching assembly 40 can also effectively control the sequential switching of the first hinge member 31 and the second hinge member 32, i.e. when the door 20 is in the closing process 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, the switching assembly 40 locks the first hinge member 31, when the door 20 is in the closing process from the second opening angle α2 to the first opening angle α1, the first slide group 401 and the second slide group 402 relatively move to disengage the first hinge member 31 from the limit of the switching assembly 40, and the fourth shaft 322 is limited in the fourth limit section 4222, the switching assembly 40 locks the second hinge member 32, and when the door 20 is in the closing process from the first opening angle α1 to the full closing process, 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 the processes in reverse order, and the switching sequence of the first hinge member 31 and the second hinge member 32 in the opening and closing process of the door body 20 can be effectively controlled by the unlocking and locking actions of the switching assembly 40 on the first hinge member 31 and the second hinge member 32.
In the present embodiment, the first shaft body 311 and the third shaft body 321 are offset from each other.
When the door 20 is in the process of opening from the closed state to the first opening angle α1, the door 20 rotates around the first shaft 311 as a central axis, and when the door 20 is in the process of continuing to open from the second opening angle α2 to the maximum opening angle α3, the door 20 rotates around the third shaft 321 as an axis.
When the first shaft body 311 is used as a central shaft, a first distance is reserved between the first shaft body 311 and the front end face 103 of the box body 10, a third distance is reserved between the first shaft body 311 and the outer side face 13 of the box body 10, when the third shaft body 321 is used as a central shaft, a second distance is reserved between the third shaft body 321 and the front end face 103 of the box body 10, a fourth distance is reserved between the third shaft body 321 and the outer side face 13 of the box body 10, the second distance is larger than the first distance, and the fourth distance is smaller than the third distance.
Referring to the foregoing description, the hinge assembly 30 of the present embodiment may be applicable to a built-in cabinet or a scene where a space accommodating the refrigerator 100 is small.
In addition, it should be noted that, the motion track of the door body 20 can be effectively controlled by a specific shaft body groove design, in this embodiment, the case body 10 includes a pivot side P connected to the hinge assembly 30, when the door body 20 is in the opening process, the hinge assembly 30 drives at least the door body 20 to move from the pivot side P toward the accommodating chamber D, so as to avoid interference between the door body 20 and a peripheral cabinet or wall body during the opening process, and the specific design of the shaft body groove can be referred to as the following example.
In an example, the first free section S1 includes an initial position A1 and a stop position A2 that are disposed opposite to each other, and the second free section S2 includes a first section L1, a second section L2, and a third section L3 that are sequentially connected to each other.
Referring to fig. 7 to 10, when the door 20 is in the 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 segment L1 away from the second segment L2, and the fourth shaft 322 is located at the limiting segment 4222, so that the switching assembly 40 limits the second hinge member 32.
Referring to fig. 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 place at the initial position A1, the second shaft 312 moves in the first section L1 around the first shaft 311, the door 20 rotates in place relative to the case 10, then the second shaft 312 moves in the second section L2 to drive the first shaft 311 to move from the initial position A1 to the stop position A2, the door 20 moves from the pivot side P toward the receiving chamber D, and then the second shaft 312 moves in the third section L3 to drive the first shaft 311 to move from the stop position A2 toward the initial position A1, and the door 20 moves from the receiving chamber D toward the pivot side P.
Specifically, referring to fig. 11 to 14, when the door 20 is in the process of opening from the closed state to the first intermediate opening angle α11, the first shaft 311 rotates in place at the initial position A1, and the second shaft 312 moves in the first section L1 around the first shaft 311, so that the door 20 rotates in place relative to the case 10.
Here, when the door 20 is in the process of opening from the closed state to the first intermediate opening angle α11, the door 20 rotates in place relative to the case 10, that is, the door 20 only rotates without generating displacement in other directions, so that the door 20 cannot be opened normally due to displacement in a certain direction of the door 20 can be effectively avoided.
Referring to fig. 15 to 18, when the door 20 is in the process of being opened from the first intermediate opening angle α11 to the second intermediate opening angle α12, the second shaft 312 moves in the second section L2 to drive the first shaft 311 to move from the initial position A1 to the stop position A2, and the door 20 moves from the pivot side P toward the receiving chamber D.
Here, when the door 20 is in the process of continuing to open from the first intermediate opening angle to the second intermediate opening angle, the door 20 moves toward the side of the accommodating chamber D, that is, the door 20 rotates relative to the case 10 and displaces relative to the case 10 along the first direction X, so that the distance that the door 20 protrudes from the case 10 toward the side far from the accommodating chamber D during rotation is greatly reduced, that is, the displacement of the door 20 along the first direction X counteracts the portion that protrudes from the case 10 along the second direction Y during rotation of the door 20, thereby avoiding interference between the door 20 and the surrounding cabinet or wall during opening, and being suitable for a scene with a small space of the embedded cabinet or accommodating the refrigerator 100.
Here, the first direction X is a direction in which the pivot side P faces the accommodation chamber D, and the second direction Y is a direction in which the accommodation chamber D faces the pivot side P.
Referring to fig. 19 to 22, when the door 20 is in the process of being opened from the second intermediate opening angle α12 to the first opening angle α1, the second shaft 312 moves in the third section L3 to drive the first shaft 311 to move from the stop position A2 toward the initial position A1, and the door 20 moves from the receiving chamber D toward the pivot side P.
Here, when the door 20 is in the process of opening from the second intermediate opening angle to the first opening angle α1, the door 20 moves toward one side of the pivoting side P, that is, the door 20 rotates relative to the case 10 and displaces relative to the case 10 along the second direction Y, so that the door 20 is far away from the case 10 as far as possible, the opening of the case 10 is ensured, and the problem that drawers, racks, and the like in the case 10 cannot be opened due to interference of the door 20 is avoided.
Referring to fig. 23 to 26, when the door 20 is in the process of continuing to open from the first opening angle α1 to the second opening angle α2, the fourth shaft 322 is separated from the limiting segment 4222, and the first shaft 311 and/or the second shaft 312 are limited by the locking segments 4132, 4142, 4152, 4162, so that the switching assembly 40 limits the first hinge member 31.
Referring to fig. 27 to 30, when the door 20 is in the process of continuing to open from the second opening angle α2 to the maximum opening angle α3, the third shaft 321 rotates in situ in the third free section 421, the fourth shaft 322 moves in the fourth free section 4221 around the third shaft 321, and the door 20 continues to rotate in situ relative to the case 10.
It should be understood that the motion track of the refrigerator 100 is not limited to the above description, and in other examples, other forms of motion may be generated between the first hinge member 31 and the switching assembly 40, or other forms of motion may be generated between the second hinge member 32 and the switching assembly 40, so that the refrigerator can adapt to various application scenarios, and may be specific to practical situations.
For example, the door body 20 of the refrigerator 100 is moved toward the receiving chamber D only by the pivoting side P during the opening process to avoid interference of the door body 20 with a surrounding cabinet or wall body or the like during the opening process, or the door body 20 of the refrigerator 100 is moved toward the front end surface 103 away from the cabinet 10 during the opening process to avoid interference of the door body 20 with the door seal, or the door body 20 of the refrigerator 100 is moved toward the pivoting side P only by the receiving chamber D during the opening process to increase the opening degree of the cabinet 10, or the center of gravity of the door body 20 of the refrigerator 100 is moved toward the cabinet 10 during the opening process to avoid toppling of the refrigerator or the like.
In this embodiment, referring to fig. 31 to 33, the hinge assembly 30 further includes a frame 60, the frame 60 is fixed to the periphery of the switching assembly 40, and the frame 60 extends along the first direction to cover the periphery of the switching assembly 40.
Here, the switching unit 40 is sandwiched between the first hinge member 31 and the second hinge member 32, and when the hinge unit 30 is mounted to the refrigerator 100, the switching unit 40 is generally exposed above or below the door 20, which affects the aesthetic appearance, and the main function of the frame 60 in the present embodiment is to form a shield around the periphery of the switching unit 40, so as to improve the overall aesthetic appearance of the hinge unit 30.
In addition, the "the frame 60 extends along the first direction to block the periphery of the switching assembly 40" means that the frame 60 blocks most or all of the periphery of the switching assembly 40, that is, the frame 60 blocks the periphery of the switching assembly 40 as a whole when viewed from the side of the hinge assembly 30, but the switching assembly 40 may still have a partial structure that is not blocked by the frame 60.
In the present embodiment, the frame 60 is an integrally formed structure, which can further improve the overall aesthetic appearance.
The inner contour of the frame 60 is matched with the outer contour of the switching assembly 40, the frame 60 is of a rectangular frame structure with a closed circumference, namely, the frame 60 is of a hollow frame structure, so that a shielding effect can be achieved on the whole periphery of the switching assembly 40, and the attractiveness of the hinge assembly 30 in the whole opening process is guaranteed.
In the present embodiment, the switching assembly 40 includes a first end surface 403 facing the first hinge member 31 and a second end surface 404 facing the second hinge member 32, the frame 60 includes a first frame-shaped end 61 facing the first hinge member 31 and a second frame-shaped end 62 facing the second hinge member 32, and the first frame-shaped end 61 is flush with the first end surface 403 and/or the second frame-shaped end 62 is flush with the second end surface 404, so that the shielding effect of the frame 60 can be improved, and the space among the first hinge member 31, the switching assembly 40 and the second hinge member 32 can be made more compact.

In this embodiment, the bezel 60 includes a bezel outer edge 63 remote from the switching assembly 40, at least a portion of the bezel outer edge 63 being flush with at least a portion of the outer edge of the first hinge member 31 when the hinge assembly 30 is in the closed state.
Here, when the hinge assembly 30 is in the closed state, the rim outer edge 63 of the switching assembly 40 is flush with the outer edge of the first hinge member 31 in an area (i.e., a visually visible area) near the outside of the refrigerator 100, so that the overall aesthetic degree of the refrigerator 100 can be further improved.
In the present embodiment, the hinge assembly 30 further includes a decorative frame 70, and the decorative frame 70 is sleeved on a side of the frame 60 away from the switching assembly 40.
Here, the decorative frame 70 is in a "[" shape, which facilitates the mounting of the decorative frame 70 to the outside of the rim 60.
That is, the decorative frame 70 is not completely wrapped around the frame 60, and the portion not completely wrapped is preferably located in an area that is not exposed during the opening process of the door body 20, and the structure of the decorative frame 70 is not limited to the above description.
It should be noted that, when the decorative frame 70 is combined to the exterior of the bezel 60, when the hinge assembly 30 is in the closed state, at least a portion of the edge of the decorative frame 70 is flush with at least a portion of the outer edge of the first hinge member 31, but not limited thereto.
The decorative frame 70 is connected with the frame 60 through the buckle 71, so that the decorative frame 70 is convenient to mount and dismount.
The frame 60 is made of POM (polyoxymethylene) material, the decorative frame 70 is made of ABS (Acrylonitrile Butadiene Styrene) plastic, and ABS material is easy to color, so that the color of the switching assembly 40 and the refrigerator 100 are unified, and of course, the materials of the frame 60 and the decorative frame 70 are not limited to the above description.
In the present embodiment, the decorative frame 70 includes a first end 72 near the first hinge member 31 and a second end 73 near the second hinge member 32.
The first end 72 of the decorative frame 70 is further away from the first hinge member 31 than the first frame end 61 of the frame 60, so that the decorative frame 70 and the first hinge member 31 are prevented from interfering with each other when the switching assembly 40 rotates relative to the first hinge member 31.
Similarly, the second end 73 of the decorative frame 70 is further away from the second hinge member 32 than the second frame-shaped end 62 of the frame 60, so that the decorative frame 70 and the second hinge member 32 are prevented from interfering with each other when the switching assembly 40 rotates relative to the second hinge member 32.
In this embodiment, referring to fig. 32 and 33, the switching assembly 40 includes a first slide group 401 and a second slide group 402 stacked along a first direction, and the frame 60 is fixedly disposed on the first slide group 401 or the second slide group 402.
Specifically, in the direction of the first hinge member 31 toward the second hinge member 32, the switching assembly 40 sequentially includes a first liner 4011, a first sliding sheet 4012, an intermediate liner 4013, a second sliding sheet 4021 and a second liner 4022, and the frame 60 is fixedly disposed on one of the first liner 4011, the first sliding sheet 4012, the intermediate liner 4013, the second sliding sheet 4021 and the second liner 4022.
The first liner 4011, the first sliding sheet 4012 and the intermediate liner 4013 are sequentially stacked to form a first sliding sheet set 401, the second sliding sheet 4021 and the second liner 4022 are stacked to form a second sliding sheet set 402, but not limited thereto, for example, the first liner 4011 may be stacked with the first sliding sheet 4012 to form the first sliding sheet set 401, and the intermediate liner 4013, the second sliding sheet 4021 and the second liner 4022 may be sequentially stacked to form the second sliding sheet set 402.
In general, the first liner 4011, the intermediate liner 4013, and the second liner 4022 are made of plastic, for example, POM (polyoxymethylene) or the like.
The first sliding piece 4012 and the second sliding piece 4021 are made of metal, for example, stainless steel or Q235 steel.
Here, the first sliding piece 4012 and the second sliding piece 4021 are prevented from being directly contacted and friction-interfered with each other by wrapping the sliding piece made of metal material with the plastic material, and the second sliding piece 4021 is directly contacted with the middle lining 4013 in the first sliding piece set 401, so that the structure of the second sliding piece set 402 can be simplified, and the overall thickness of the switching assembly 40 can be further reduced.
The frame 60 is integrally formed with one of the first liner 4011, the first sliding sheet 4012, the middle liner 4013, the second sliding sheet 4021 and the second liner 4022, so as to improve overall strength and aesthetic appearance, and is convenient to implement, but not limited thereto.

The frame 60 extends toward the second hinge 32 to cover most of the periphery of the switching assembly 40, and the frame 60 does not cover the first sliding sheet 4011, that is, the periphery of the first sliding sheet 4012, the middle sliding sheet 4013, the second sliding sheet 4021 and the second sliding sheet 4022 are not exposed, and the periphery of the first sliding sheet 4011 is exposed, so that the second sliding sheet set 402 moves relative to the first sliding sheet set 401 in a space defined by the frame 60.
It will be appreciated that in other examples, the bezel 60 may also cover the perimeter of the first patch 4011.
In the fourth example, the frame 60 is connected to the periphery of the second sliding piece 4021, and the frame 60 may be made of metal, but is not limited thereto.
The frame 60 extends towards the first hinge member 31 and the second hinge member 32 respectively to cover most of the periphery of the switching assembly 40, and the frame 60 does not cover the first sliding sheet 4011, that is, the periphery of the first sliding sheet 4012, the middle sliding sheet 4013, the second sliding sheet 4021 and the second sliding sheet 4022 are not exposed, and the periphery of the first sliding sheet 4011 is exposed, so that the second sliding sheet set 402 moves relative to the first sliding sheet set 401 in a space formed by surrounding the frame 60.

In the second embodiment, the hinge assembly 30a includes a first hinge member 31a provided to the case 10, a second hinge member 32a provided to the door 20, and a switching assembly 40a connecting the first hinge member 31a and the second hinge member 32a, the hinge assembly 30a further includes a cover plate 80a and a frame 60a, the cover plate 80a is located at a side of the switching assembly 40a adjacent to the second hinge member 32a, the frame 60a is connected to the cover plate 80a, and the frame 60a extends along the first direction to shield the periphery of the switching assembly 40 a.
Here, the switching component 40a is sandwiched between the first hinge member 31a and the second hinge member 32a, when the second hinge member 32a moves relative to the switching component 40a, a side of the switching component 40a close to the second hinge member 32a is exposed, and by providing the cover plate 80a, a shielding effect can be achieved on a side of the switching component 40a close to the second hinge member 32a, so that external dust or impurities can be prevented from entering the switching component 40a, and the overall aesthetic appearance can be improved.
It will be appreciated that a cover plate may be provided on the side of the switching assembly 40a adjacent the first hinge member 31a, if desired.
Moreover, when the hinge assembly 30a is mounted to the refrigerator 100, the switching assembly 40a is generally exposed above or below the door body 20, affecting the aesthetic appearance, and the main effect of the frame 60a in the present embodiment is to form a shadow at the periphery of the switching assembly 40a, improving the overall aesthetic appearance of the hinge assembly 30 a.
In addition, "the frame 60a extends along the first direction to block the periphery of the switching assembly 40 a" means that the frame 60a blocks most or all of the periphery of the switching assembly 40a, that is, the frame 60a blocks the periphery of the switching assembly 40a as a whole when viewed from the side of the hinge assembly 30a, but the switching assembly 40a may still have a partial structure that is not blocked by the frame 60 a.

Here, the first sliding piece 4012c and the second sliding piece 4021c are prevented from being directly contacted and friction-interfered with each other by wrapping the sliding piece made of metal with the plastic material, and the second sliding piece 4021c is directly contacted with the middle lining 4013c in the first sliding piece set 401c, so that the structure of the second sliding piece set 402c can be simplified, and the overall thickness of the switching assembly 40c can be further reduced.
In the present embodiment, a gap may be provided between the cover plate 80c and the second slider group 402c, or the cover plate 80c contacts the second slider group 402c.
In the present embodiment, the switching unit 40c and the second hinge member 32c are engaged with the grooves 421c and 422c through the shaft bodies 321c and 322c, and the cover plate 80c has the through holes 84c and 85c through which the shaft bodies pass.

That is, the cover plate 80c and the first sliding vane set 401c enclose a cavity S, the second sliding vane set 402c is located in the cavity S, and a gap is formed between the second sliding vane set 402c and the cover plate 80c, and the cover plate 80c contacts the second hinge member 32 c.
At this time, when the gravity of the door 20 acts on the second hinge member 32c, the second hinge member 32c transmits the gravity to the cover plate 80c, and the cover plate 80c sequentially transmits the gravity to the first sliding vane set 401c and the first hinge member 31c, that is, the gravity is not transmitted to the second sliding vane set 402c, and the second sliding vane set 402c can move smoothly in the cavity S relative to the first sliding vane set 401c.
That is, at this time, the cover plate 80c not only plays a role of shielding, but also plays a role of gravity transmission, and the contact area between the cover plate 80c and the second hinge member 32c is larger, so that the cover plate 80c can more stably and efficiently transmit gravity to the first sliding sheet set 401c, and wear of the hinge assembly 30c can be reduced as much as possible, and the hinge assembly 30c can work more smoothly.
It should be noted that, the cover plate 80c may be connected to the first slide 4012c in the first slide group 401c, and since the first slide 4012c is made of metal, the cover plate 80c may be stably supported, and of course, the cover plate 80c may be connected to the first lining 4011c or the intermediate lining 4013c.
When the cover plate 80c contacts the second sliding plate set 402c, the cover plate 80c is fixedly arranged on the first sliding plate set 401c or the second sliding plate set 402c, and at this time, the cover plate 80c plays a role of shielding.

At this time, when the gravity of the door body 20 acts on the second hinge member 32c, the second hinge member 32c transmits the gravity to the cover plate 80c, and the cover plate 80c sequentially transmits the gravity to the second sliding vane set 402c and the first hinge member 31c, that is, the gravity is not transmitted to the first sliding vane set 401c, and the first sliding vane set 401c can move smoothly relative to the second sliding vane set 402c in the cavity S.
That is, at this time, the cover plate 80c not only plays a role of shielding, but also plays a role of gravity transmission, and the contact area between the cover plate 80c and the second hinge member 32c is larger, so that the cover plate 80c can more stably and efficiently transmit gravity to the second sliding vane set 402c, and wear of the hinge assembly 30c can be reduced as much as possible, and the hinge assembly 30c can work more smoothly.
It should be noted that, the cover plate 80c may be connected to the second sliding piece 4021c in the second sliding piece set 402c, and since the second sliding piece 4021c is made of metal, the cover plate 80c may be stably supported, and of course, the cover plate 80c may also be connected to the second lining 4022c.
It should be noted that, in this case, the cover plate 80c may not be provided, and the second hinge member 32c directly contacts the second slider assembly 402c.
