[0054] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0055] In the various drawings of the present invention, for the sake of convenience, some sizes of structures or parts are exaggerated relative to other structures or parts, and thus, only the basic structure of the subject matter of the present invention is illustrated.

[0056] Ginseng Figure 1 , which is a schematic diagram of a refrigeration device 100 according to an embodiment of the present invention.

[0057] The refrigeration device 100 includes a cabinet 10 , a door 20 , and a hinge assembly 30 connecting the cabinet 10 and the door 20 .

[0058] It should be noted that the refrigeration device 100 may be a refrigerator, a freezer, a wine cabinet, etc. Here, the refrigeration device 100 is taken as an example of a refrigerator.

[0059] In addition, the hinge assembly 30 is not only applicable to the refrigeration device 100, but also applicable to other scenarios, such as cabinets, wardrobes, etc. The present invention uses the hinge assembly 30 applied to the refrigerator 100 as an example for illustration, but is not limited to this.

[0060] Combine Figures 2 to 4 , which is a schematic diagram of the hinge assembly 30 according to the first embodiment of the present invention.

[0061] The hinge assembly 30 includes a first hinge member 31 connected to the box body 10 , a second hinge member 32 connected to the door body 20 , and a sliding plate assembly 40 connecting the first hinge member 31 and the second hinge member 32 .

[0062] Here, “the first hinge 31 connected to the box body 10 ” means that the first hinge 31 is connected to the box body 10 . The first hinge 31 may be an independent component mounted to the box body 10 , or may be a component directly integrally formed on the box body 10 .

[0063] Similarly, “the second hinge member 32 connected to the door body 20 ” means that the second hinge member 32 is connected to the door body 20 . The second hinge member 32 may be an independent component mounted to the door body 20 , or may be a component directly integrally formed on the door body 20 .

[0064] The first hinge 31 and the slide assembly 40 cooperate with each other through the first rotation group B1 and the first limit group C1 , and the second hinge 32 and the slide assembly 40 cooperate with each other through the second rotation group B2 and the second limit group C2 .

[0065] Here, the first rotation group B1 is a component for controlling the in-place rotation of the sliding assembly 40 relative to the first hinge member 31, the first limit group C1 is a component for controlling the locking or unlocking between the sliding assembly 40 and the first hinge member 31, the second rotation group B2 is a component for controlling the in-place rotation of the second hinge member 32 relative to the sliding assembly 40, and the second limit group C2 is a component for controlling the locking or unlocking between the sliding assembly 40 and the second hinge member 32.

[0066] When the hinge assembly 30 is in the opening process, the second hinge component 32 locks the sliding assembly 40 through the second limit group C2, and the second hinge component 32 and the sliding assembly 40 rotate in place relative to the first hinge component 31 through the first rotation group B1.

[0067] It should be noted that "the hinge assembly 30 is in the opening process" means that the second hinge member 32 opens in a direction away from the first hinge member 31, that is, the second hinge member 32 is acted in one direction to drive the second hinge member 32 to move in a direction away from the first hinge member 31. 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.

[0068] At this time, the second limit group C2 is actuated to control the locking between the slide assembly 40 and the second hinge member 32, that is, the second hinge member 32 and the slide assembly 40 are relatively stationary, while the first limit group C1 is not actuated, the first hinge member 31 and the slide assembly 40 are in an unlocked state, and the first rotation group B1 controls the second hinge member 32 and the slide assembly 40 to rotate in place relative to the first hinge member 31.

[0069] Here, “action” refers to the opening operation of the second limiting group C2 , that is, the second limiting group C2 plays a role in the opening process of the hinge assembly 30 , and the same applies hereinafter.

[0070] Then, the first limiting group C1 acts on the slide assembly 40 to move relative to the first hinge 31 and the second hinge 32 at the same time. The first hinge 31 locks the slide assembly 40 through the first limiting group C1, and the second hinge 32 unlocks the slide assembly 40 through the second limiting group C2.

[0071] At this time, the first limit group C1 is actuated to control the movement of the slide assembly 40, and the relative position between the slide assembly 40 and the first hinge member 31 and the second hinge member 32 changes, so that the locking and unlocking states between the slide assembly 40 and the first hinge member 31 and the second hinge member 32 also change. Specifically, at this time, the first hinge member 31 and the slide assembly 40 are in a locked state, and the second hinge member 32 and the slide assembly 40 are in an unlocked state.

[0072] Then, the second hinge member 32 rotates in place relative to the sliding plate assembly 40 through the second rotation group B2.

[0073] At this time, the first hinge 31 and the sliding assembly 40 are relatively stationary, and the second rotation group B2 controls the second hinge 32 to rotate in situ relative to the entirety of the sliding assembly 40 and the first hinge 31 .

[0074] In this embodiment, the locking and unlocking between the first hinge part 31, the second hinge part 32 and the sliding assembly 40 can be controlled by the first limiting group C1 and the second limiting group C2. Specifically, the second hinge part 32 and the sliding assembly 40 are first locked to each other by the second limiting group C2, and then the first rotating group B1 is controlled to be actuated to drive the second hinge part 32 and the sliding assembly 40 to rotate in situ relative to the first hinge part 31. Then, the second hinge part 32 and the sliding assembly 40 are unlocked and the first hinge part 31 and the sliding assembly 40 are locked to each other by the first limiting group C1 and the second limiting group C2, and then the second rotating group B2 is controlled to be actuated to drive the second hinge part 32 to rotate in situ relative to the sliding assembly 40.

[0075] It can be seen that the first rotation group B1 and the second rotation group B2 of this embodiment are respectively used to realize the in-situ rotation between the first hinge 31 and the slide assembly 40 and between the second hinge 32 and the slide assembly 40. The first limit group C1 and the second limit group C2 can effectively control the order of the two in-situ rotations. There is a change in the position of the rotation axis during the two in-situ rotations, which can effectively control the movement trajectory of the door body, thereby improving the degree of freedom of the opening and closing process of the door body 20 of the refrigerator 100, especially in the field of built-in refrigerators. The switching of the rotation axis can avoid the door body 20 from interfering with the surrounding cabinets or walls during the opening and closing process.

[0076] It can be understood that the first limiting group C1 and the second limiting group C2 can be mechanical structures or electronic control structures to control the order of the two rotations in situ.

[0077] In this embodiment, the first rotating group B1 includes a first shaft 311, a first groove 411, a second shaft 312, and a second groove 412. The first shaft 311 rotates in place within the first groove 411, and the second shaft 312 moves within the second groove 412 with the first shaft 311 as the center. The second rotating group B2 includes a third shaft 321, a third groove 421, a fourth shaft 322, and a fourth groove 422. The third shaft 321 rotates in place within the third groove 421, and the fourth shaft 322 moves within the fourth groove 422 with the third shaft 321 as the center.

[0078] That is to say, the first in-situ rotation process of the hinge assembly 30 is centered on the first axis 311, and the second axis 312 moves along the arc segment in the second groove 412. The second in-situ rotation process of the hinge assembly 30 is centered on the third axis 321, and the fourth axis 322 moves along the arc segment in the fourth groove 422.

[0079] In order to further illustrate the motion trajectory of the hinge assembly 30, Figure 5, 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 used as an example for explanation.

[0080] 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 accommodating chamber D and an outer side surface 13 adjacent to the hinge assembly 30 and on an extension section of the rotation path of the door body 20. The door body 20 includes a front wall 21 away from the accommodating chamber D and a side wall 22 always sandwiched between the front wall 21 and the accommodating chamber D. There is a side edge 23 between the front wall 21 and the side wall 22.

[0081] The hinge assembly 30 is configured as follows: when the first rotating group B1 is actuated, that is, when the first shaft 311 serves as the rotating axis, there is a first distance between the first shaft 311 and the front end surface 103 of the box body 10; when the second rotating group B2 is actuated, that is, when the third shaft 321 serves as the rotating axis, there is a second distance between the third shaft 321 and the front end surface 103 of the box body 10, and the second distance is greater than the first distance.

[0082] When the first rotating group B1 is actuated, that is, when the first shaft 311 serves as the rotating axis, there is a third distance between the first shaft 311 and the outer side surface 13 of the box body 10. When the second rotating group B2 is actuated, that is, when the third shaft 321 serves as the rotating axis, there is a fourth distance between the third shaft 321 and the outer side surface 13 of the box body 10. The fourth distance is smaller than the third distance.

[0083] It should be noted that the above distance refers to the distance between the first shaft 311, the third shaft 321 and the front end face 103 and the outer side face 13 of the box body 10 when the hinge assembly 30 moves to a certain position, rather than the distance in the closed state.

[0084] The specific instructions are as follows:

[0085] In actual operation, in order to improve the embedding effect, it is better to make the refrigerator 100 completely embedded in the cabinet 200. The refrigerator 100 is a free embedded refrigerator, that is, the front end 201 of the cabinet 200 and the front wall 21 of the door body 20 away from the box body 10 are in 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.

[0086] In the prior art, 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, so that there is enough space to meet the needs of foaming or other processes. That is, the rotating axis position of the existing refrigerator is approximately Figure 5In this case, after the single-axis refrigerator is embedded in the cabinet 200, since the corner 203 of the cabinet 200 between the front end 201 and the inner wall 202 corresponds 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 usual practice in the prior art is to increase the distance between the inner wall 202 of the cabinet 200 and the refrigerator 100. The distance needs to be about 10 cm, which will seriously affect the embedding effect and is not conducive to the rational use of limited space.

[0087] Combine Figure 5 , the shaded area represents the door body 20 in the closed state. When the door body 20 is in the opening process, if the door body 20 always rotates with the first shaft 311 as the rotation axis (i.e., the prior art), refer to Figure 5 In the dotted door body 20', since the first axis 311 is close to the front end surface 103, that is, the first axis 311 is 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 interfere with the door body 20' and limit the maximum opening angle of the door body 20'.

[0088] When the second hinge 32 and the sliding plate assembly 40 are rotated relative to each other at a certain angle, the third hinge shaft 321 and the cabinet 10 also change in position, and the third hinge shaft 321 gradually moves away from the front end surface 103, that is, the third hinge shaft 321 gradually moves toward the front end 201 of the cabinet 200. At this time, the door body 20 rotates in place with the third hinge shaft 321 at the current position as the rotation axis. Since the third hinge shaft 321 is farther away from the front end surface 103 of the cabinet 10 than the first hinge shaft 311, the third hinge shaft 321 is rotated relative to the first hinge shaft 31 Figure 5 In the solid line door body 20, the interference effect of the 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 corners 203 of the cabinet 200 interfere with each other, thereby greatly improving the maximum opening angle of the door body 20.

[0089] That is to say, in this embodiment, after the door body 20 is opened to a certain angle, it switches to rotation with the third axis 321 as the rotation axis. Under the premise of ensuring that the refrigerator 100 is freely embedded in the cabinet 200, the maximum opening angle of the door body 20 can be effectively increased, thereby making it easier for users to operate the refrigerator 100 and greatly improving the user experience.

[0090] 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, greatly improving the embedding effect.

[0091] In addition, the third axis 321 of this embodiment gradually moves toward the front end 201 of the cabinet 200 while also gradually moving toward the inner wall 202 of the cabinet 200. That is, when the door body 20 rotates with the third axis 321 as the axis, the third axis 321 is closer to the front end 201 and the inner wall 202 of the cabinet 200 than the first axis 311. In this way, the maximum opening angle of the door body 20 can be increased, and the door body 20 can be moved away from the box body 10 to increase the opening of the box body 10, which is convenient for opening and closing shelves, drawers, etc. in the box body 10, or in other words, it is convenient for taking and putting items.

[0092] Of course, the third axis 321 which ultimately serves as the rotation axis can also be located at other positions. For example, when the door body 20 rotates around the third axis 321, the third axis 321 is closer to the front end 201 of the cabinet 200 than the first axis 311, and the third axis 321 is farther away from the inner wall 202 of the cabinet 200 than the first axis 311, and so on.

[0093] It can be understood that the slide assembly 40 controls the switching sequence of the first hinge 31 and the second hinge 32 during the opening and closing process of the door body 20, which can effectively avoid the door body 20 from interfering with the cabinet 200 during the opening and closing process.

[0094] In this embodiment, the shaft grooves may include various distribution forms, specifically including:

[0095] The first shaft 311 is located at one of the first hinge 31 and the sliding assembly 40 , and the first slot 411 is located at the other of the first hinge 31 and the sliding assembly 40 .

[0096] The second shaft 312 is located at one of the first hinge 31 and the sliding assembly 40 , and the second slot 412 is located at the other of the first hinge 31 and the sliding assembly 40 .

[0097] The third shaft 321 is located at one of the second hinge 32 and the sliding assembly 40 , and the third slot 421 is located at the other of the second hinge 32 and the sliding assembly 40 .

[0098] The fourth shaft 322 is located at one of the second hinge 32 and the sliding assembly 40 , and the fourth slot 422 is located at the other of the second hinge 32 and the sliding assembly 40 .

[0099] In this embodiment, the first shaft 311 and the second groove 412 are located in the first hinge 31 , the first groove 411 and the second shaft 312 are located in the slide assembly 40 , the third shaft 321 and the fourth shaft 322 are located in the slide assembly 40 , and the third groove 421 and the fourth groove 422 are located in the second hinge 32 as an example.

[0100] It is understandable that in other embodiments, the position of the shaft groove can be freely selected according to actual needs and is not limited to the position of the shaft groove in this embodiment.

[0101] The specific design of the hinge assembly 30 of this embodiment can refer to the following examples. It can be understood that the following are only illustrative examples. In other embodiments, the hinge assembly 30 can also have other structures.

[0102] In this embodiment, combined with Figure 6 and Figure 7 The first limiting group C1 includes a first limiting section C11 connected to the second groove body 412, and the second limiting group C2 includes a second limiting section C21 connected to the fourth groove body 422. When the second shaft body 312 is located in the first limiting section C11, the first hinge member 31 locks the sliding assembly 40, and when the fourth shaft body 322 is located in the second limiting section C21, the second hinge member 32 locks the sliding assembly 40.

[0103] That is to say, the first limiting group C1 includes a first limiting section C11 and a second shaft 312 that cooperate with each other, and the first limiting section C11 is connected to the second groove 412. When the second shaft 312 is located in the second groove 412, the first limiting section C11 is not effective, and the sliding assembly 40 and the first hinge member 31 can rotate relative to each other in place through the second shaft 312 and the second groove 412. When the second shaft 312 moves into the first limiting section C11, the first limiting section C11 locks the second shaft 312, and the sliding assembly 40 and the first hinge member 31 cannot move relative to each other.

[0104] Similarly, the second limiting group C2 includes a second limiting section C21 and a fourth axis 322 that cooperate with each other, and the second limiting section C21 is connected to the fourth groove 422. When the fourth axis 322 is located in the second limiting section C21, the second limiting section C21 locks the fourth axis 322, and the sliding assembly 40 and the second hinge member 32 cannot move relative to each other. When the fourth axis 322 moves into the fourth groove 422, the second limiting section C21 does not work, and the sliding assembly 40 and the second hinge member 32 can rotate relative to each other in place through the fourth axis 322 and the fourth groove 422.

[0105] It can be seen that this embodiment controls the locking and unlocking between the first hinge 31 and the sliding assembly 40, and the second hinge 32 and the sliding assembly 40 by controlling the positions of the second shaft 312 and the fourth shaft 322, thereby realizing two in-situ rotations with different rotation axes in sequence.

[0106] In addition, in this embodiment, the first limiting group C1 and the first rotating group B1 share the second shaft 312, the first limiting section C11 is connected to the second groove 412, the second limiting group C2 and the second rotating group B2 share the fourth shaft 322, and the second limiting section C21 is connected to the fourth groove 422, which can greatly simplify the overall structure.

[0107] Here, the first limiting section C11 and the second groove body 412 have different centers, and the second limiting section C21 and the fourth groove body 422 have different centers, that is, unlocking and locking are achieved by changing the trajectory of the groove, which will be explained in detail below.

[0108] In this embodiment, combined with Figure 6 and Figure 7 The slide assembly 40 includes a first slide 401 and a second slide 402 that are movably connected.

[0109] The first slide 401 and the second slide 402 are rotatably connected via a pivot shaft 501 and a pivot slot 502 .

[0110] At least a portion of the first sliding plate 401 is closer to the first hinge 31 than the second sliding plate 402 .

[0111] Specifically, the first slide 401 includes a first portion 4011 and a second portion 4012 fixed to each other. The first portion 4011 is arranged between the first hinge 31 and the second slide 402 , and the second portion 4012 and the second slide 402 are arranged side by side between the first portion 4011 and the second hinge 32 .

[0112] Here, the first part 4011 and the second part 4012 can be an integrally molded structure or a structure that is spliced ​​together after being molded separately. The thickness of the second part 4012 is roughly equal to that of the second slide 402, and the second part 4012 and the second slide 402 are spaced apart. On the one hand, the second part 4012 and the second slide 402 are clamped together between the first part 4011 and the second hinge member 32, which can improve the stability and overall aesthetics of the entire hinge assembly 30 and is conducive to the transmission of force. On the other hand, there is a gap between the second slide 402 and the second part 4012, which facilitates the relative movement of the second slide 402 and the first slide 401.

[0113] The first slide 401 is connected to the first hinge part 31 through the first axis 311 and the first groove 411, the second slide 402 is connected to the first hinge part 31 through the second axis 312 and the second groove 412, and the second slide 402 is connected to the first hinge part 31 through the first limit group C1, that is, the second slide 402 is connected to the first hinge part 31 through the second axis 312 and the second groove 412 and the first limit section C11 that are interconnected.

[0114] Specifically, the first shaft 311 is fixed to the first hinge 31 and extends toward the first slide 401 . The first slot 411 is a circular hole located in the first slide 401 . The circular hole passes through the first portion 4011 and the second portion 4012 . The first shaft 311 extends into the first slot 411 .

[0115] The second groove body 412 and the first limiting section C11, which are interconnected, are located on the first hinge part 31 and pass through the first hinge part 31. The second shaft body 312 is fixed to the second slide 402. An auxiliary limiting groove 4013 is provided on the first part 4011 of the first slide 401. The second shaft body 312 passes through the auxiliary limiting groove 4013 and extends to the second groove body 412 and the first limiting section C11. The opening size of the auxiliary limiting groove 4013 is larger than the outer contour of the second shaft body 312.

[0116] The first slide 401 is connected to the second hinge part 32 through the third axis 321 and the third groove 421, the second slide 402 is connected to the second hinge part 32 through the fourth axis 322 and the fourth groove 422, and the second slide 402 is connected to the second hinge part 32 through the second limit group C2, that is, the second slide 402 is connected to the second hinge part 32 through the fourth axis 322 and the interconnected fourth groove 422 and the second limit section C21.

[0117] Specifically, the third shaft 321 is fixed on the second portion 4012 of the first slide 401 and extends toward the second hinge 32 . The third slot 421 is a circular hole located in the second hinge 32 , and the third shaft 321 extends into the third slot 421 .

[0118] The fourth groove 422 and the second limiting section C21 are connected to each other and are located on the second hinge 32 . The fourth shaft 322 is fixed to the second sliding piece 402 and extends to the fourth groove 422 and the second limiting section C21 .

[0119] Next, the specific working process of the hinge assembly 30 is introduced.

[0120] Combine Figures 8 to 12 When the hinge assembly 30 is in the closed state, the first shaft 311 is located in the first groove 411, the second shaft 312 is located at the end of the second groove 412 away from the first limiting section C11, the third shaft 321 is located in the third groove 421, and the fourth shaft 322 is located at the end of the second limiting section C21 away from the fourth groove 422. The second hinge component 32 locks the second slide 402 and the first slide 401.

[0121] Combine Figures 13 to 17When the hinge assembly 30 is opened to the first opening angle α1, the second hinge member 32, the second slide 402 and the first slide 401 rotate together relative to the first hinge member 31 until the second shaft 312 moves to the intersection position of the second groove 412 and the first limit section C11.

[0122] Here, since the third shaft 321 is located in the third groove 421, the fourth shaft 322 is located in the second limit section C21, and the third shaft 321 is not the rotation axis of the second limit section C21, the second slide 402 and the first slide 401 cannot rotate relative to the second hinge 32, that is, the second limit section C21 realizes the locking of the second hinge 32 with the first slide 401 and the second slide 402, and the second hinge 32, the first slide 401, and the second slide 402 form a relatively static whole, which moves in the second groove 412 with the first shaft 311 as the rotation axis through the second shaft 312, and the whole rotates in place relative to the first hinge 31 to the first opening angle α1.

[0123] Combine Figures 18 to 22 When the hinge assembly 30 continues to open to the second opening angle α2, the second shaft 312 moves to the first limit section C11, the first hinge member 31 locks the second slide 402, and the first limit section C11 drives the second slide 402 to rotate relative to the first slide 401 through the second shaft 312, and the second slide 402 drives the fourth shaft 322 to move to the fourth groove 422.

[0124] Here, when the second shaft body 312 is separated from the second groove body 412, since the first shaft body 311 is not the rotation axis of the first limit section C11, the second shaft body 312 can no longer continue to move along the arc with the first shaft body 311 as the rotation axis. At the same time, since the hinge assembly 30 continues to open, the second shaft body 312 rotates under the squeezing action of the first limit section C11, driving the second slide 402 to rotate relative to the first slide 401. During the rotation of the second slide 402 The second shaft 312 moves simultaneously in the first limiting section C11 and the auxiliary limiting groove 4013. Then, as the rotation angle of the second slide 402 increases, the first limiting section C11 and the auxiliary limiting groove 4013 stagger with each other and lock the second shaft 312. That is, the first limiting section C11 realizes the locking of the first hinge component 31 and the first slide 401 and the second slide 402, and the first hinge component 31, the first slide 401, and the second slide 402 form a relatively static whole.

[0125] In addition, during the rotation of the second slide 402 relative to the first slide 401, the second slide 402 drives the fourth shaft 322 to move from the second limit section C21 to the fourth groove 422, that is, the fourth shaft 322 is released from the lock of the second limit section C21, and the second hinge member 32 and the second slide 402 are in an unlocked state.

[0126] It should be noted that the second slide 402 and the first slide 401 rotate relative to each other through the pivot shaft 501 and the pivot slot 502, and the second limit section C21 and the auxiliary limit slot 4013 use the pivot shaft 501 as the rotation axis, but are not limited to this. The second limit section C21 and the auxiliary limit slot 4013 can be slots of other shapes.

[0127] It can be understood that since the interaction force between the second shaft body 312 and the second limiting section C21 and the auxiliary limiting groove 4013 is relatively large, in order to ensure that the second slide 402 can rotate stably relative to the first slide 401, the diameter of the second shaft body 312 can be increased to increase the strength of the second shaft body 312, for example, so that the diameter of the second shaft body 312 is larger than the diameter of the first shaft body 311.

[0128] In other embodiments, the second part 4012 of the first slide 401 has a first fixed portion, and the second slide 402 has a second fixed portion. When the hinge assembly 30 continues to open to the second opening angle α2, the second slide 402 rotates relative to the first slide 401 until the first fixed portion and the second fixed portion are limited to each other. The rotation angle of the second slide 402 relative to the first slide 401 can be controlled by the second part 4012 and the second slide 402 arranged side by side.

[0129] Combine Figures 23 to 27 When the hinge assembly 30 continues to open to the third opening angle α3, the fourth shaft 322 moves in the fourth slot 422, and the second hinge 32 rotates in place relative to the first hinge 31, the first slide 401, and the second slide 402.

[0130] At this time, the first hinge member 31, the first slide 401, and the second slide 402 are a relatively stationary whole, and the second hinge member 32 and the second slide 402 are in an unlocked state. The second hinge member 32 moves in the fourth slot 422 with the third axis 321 as the rotation axis through the fourth axis 322, and the second hinge member 32 rotates in place relative to the whole to the third opening angle α3.

Although the present invention has been described in detail with reference to preferred embodiments, for example, if the techniques of different embodiments can be used in combination to simultaneously achieve corresponding effects, such solutions are also within the scope of protection of the present invention. It should be understood by those skilled in the art that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
