Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a hinge assembly and a household appliance having the same. Background Art

[0002] Normally, the refrigerator and the door body are connected by a fixed hinge to achieve relative movement, which greatly limits the opening and closing freedom of the door body, that is, the movement trajectory of the door body cannot be freely controlled to adapt to different application scenarios.

[0003] For example, in recent years, with the progress of society and the improvement of people's living standards, ordinary users have paid more and more attention to the placement and placement of refrigerators in the home. In view of the current home decoration style, some families pursue style integration, so they need to put the refrigerator in the cupboard to form a so-called embedded refrigerator device. The refrigerator is called an embedded refrigerator. Current refrigerators are difficult to adapt to this embedded application scenario.

[0004] In view of this, it is necessary to improve the existing refrigerator to solve the above problems. Summary of the invention

[0054] The present invention will be described in detail below in conjunction with 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 a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0055] In various drawings of the present invention, for the convenience of illustration, 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] In addition, terms used herein to indicate spatial relative positions, such as "upper", "above", "lower", "below", "left", "right", etc., are used for the purpose of convenience to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. Terms of spatial relative position may be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings. For example, if the device in the figure is turned over, the units described as being "below" or "beneath" other units or features will be located "above" the other units or features. Therefore, the exemplary term "below" can encompass both the above and below orientations. The device may be oriented in other ways (rotated 90 degrees or other orientations), and the spatially related descriptors used herein interpreted accordingly.

[0057] In this embodiment, combined with Figures 1 to 9 The refrigerator 100 includes a cabinet 10, a door 20 for opening and closing the cabinet 10, and a hinge assembly 30 connecting the cabinet 10 and the door 20.

[0058] The box body 10 includes a receiving chamber S and a pivot side P connected to the hinge assembly 30 .

[0059] The hinge assembly 30 includes a first hinge component 31 , a second hinge component 32 , and a switching component 40 connecting the first hinge component 31 and the second hinge component 32 .

[0060] When the door body 20 is in the process of opening, the first hinge member 31 first moves relative to the switching assembly 40, and then the second hinge member 32 moves relative to the switching assembly 40, wherein the hinge assembly 30 first drives the door body 20 to move from the pivot side P toward the accommodating chamber S, and then drives the door body 20 to move from the accommodating chamber S toward the pivot side P, and then drives the door body 20 to continue to rotate in place relative to the box body 10.

[0061] Here, by rotating the door body 20 in situ relative to the box body 10, it can be effectively avoided that the door body 20 cannot be opened normally due to the displacement of the door body 20 in a certain direction. By moving the door body 20 from the pivot side P toward the accommodating chamber S, it can be avoided that the door body 20 interferes with the surrounding cabinets or walls during the opening process. It is suitable for built-in cabinets or scenes with a small space for accommodating the refrigerator 100. By moving the door body 20 from the accommodating chamber S toward the pivot side P, the door body 20 can be kept as far away from the box body 10 as possible, ensuring the opening degree of the box body 10 and avoiding the problem that the drawers, shelves, etc. in the box body 10 are interfered with by the door body 20 and cannot be opened. By continuing to rotate the door body 20 relative to the box body 10, the maximum opening angle of the door body can be further increased.

[0062] In addition, the present embodiment can realize the switching work between the first hinge member 31 and the second hinge member 32 through the switching component 33. The first hinge member 31 and the second hinge member 32 can respectively realize partial functions of rotating in situ, moving from the pivot side P toward the accommodating chamber S, moving from the accommodating chamber S toward the pivot side P and continuing to rotate in situ. In the present embodiment, moving from the pivot side P toward the accommodating chamber S, moving from the accommodating chamber S toward the pivot side P and continuing to rotate in situ are completed one by one in sequence.

[0063] In this embodiment, the first hinge 31 is fixed to the box body 10, the second hinge 32 is fixed to the door body 20, the switching assembly 40 includes a first matching member 41 and a second matching member 42, and the first hinge 31 and the second hinge 32 can be combined in multiple ways.

[0064] In the first combination, when the door body 20 is in the process of opening from a closed state to a first opening angle α1, the first hinge component 31 and the first matching component 41 move relative to each other to drive the door body 20 to move from the pivot side P toward the accommodating chamber S, and then the first hinge component 31 and the first matching component 41 move relative to each other to drive the door body 20 to move from the accommodating chamber S toward the pivot side P, and the second matching component 42 limits the second hinge component 32. 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 second hinge component 32 disengages from the limitation of the second matching component 42, and the first matching component 41 limits the first hinge component 31. 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 second hinge component 32 and the second matching component 42 move relative to each other to drive the door body 20 to continue to rotate in situ.

[0065] That is to say, in this example, the first hinge component 31 cooperates with the first matching component 41 to successively realize the movement of the door body 20 from the pivot side P toward the accommodating chamber S and the movement of the door body 20 from the accommodating chamber S toward the pivot side P, and the second hinge component 32 cooperates with the second matching component 42 to realize the door body 20 continuing to rotate in place, wherein the switching component 40 can realize the first hinge component 31 working first and the second hinge component 32 working later through the locking and unlocking functions.

[0066] In the second combination, when the door body 20 is in the process of opening from a closed state to a first opening angle α1, the first hinge component 31 and the first matching component 41 move relative to each other to drive the door body 20 to move from the pivot side P toward the accommodating chamber S, and the second matching component 42 limits the second hinge component 32. 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 second hinge component 32 disengages from the limitation of the second matching component 42, and the first matching component 41 limits the first hinge component 31. 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 second hinge component 32 and the second matching component 42 move relative to each other to drive the door body 20 to move from the accommodating chamber S toward the pivot side P, and then the second hinge component 32 and the second matching component 42 move relative to each other to drive the door body 20 to continue to rotate in place.

[0067] That is to say, in this example, the first hinge component 31 cooperates with the first matching component 41 to sequentially realize the movement of the door body 20 from the pivot side P toward the accommodating chamber S, and the second hinge component 32 cooperates with the second matching component 42 to sequentially realize the movement of the door body 20 from the accommodating chamber S toward the pivot side P and the door body 20 continues to rotate in situ, wherein the switching component 40 can realize the first hinge component 31 working first and the second hinge component 32 working later through the locking and unlocking functions.

[0068] The refrigerator 100 of this embodiment is described below in detail by taking the first combination mode as an example, and the refrigerator 100 takes a multi-door refrigerator 100 as an example.

[0069] Combination Figure 1 , which is a schematic diagram of a refrigerator 100 according to an embodiment of the present invention.

[0070] The refrigerator 100 includes a cabinet 10 , a door 20 for opening and closing the cabinet 10 , and a hinge assembly 30 connecting the cabinet 10 and the door 20 .

[0071] It should be emphasized that the structure of this embodiment is not only applicable to the side-by-side refrigerator 100 with the hinge assembly 30, but also applicable to other scenarios, such as cabinets, wine cabinets, wardrobes, etc. The present invention takes the side-by-side refrigerator 100 as an example for illustration, but is not limited to this.

[0072] The box body 10 includes a receiving chamber S and a pivot side P connected to the hinge assembly 30 .

[0073] Here, the "pivot side P" is defined as the area where the door body 20 rotates relative to the box body 10, that is, the area where the hinge assembly 30 is provided, the direction of the pivot side P toward the accommodating chamber S is defined as the first direction X, and the direction of the accommodating chamber S toward the pivot side P is defined as the second direction Y.

[0074] Combination Figures 2 to 9 The hinge assembly 30 includes a first hinge member 31 fixed to the box body 10 , a second hinge member 32 fixed to the door body 20 , and a switching assembly 40 connecting the first hinge member 31 and the second hinge member 32 .

[0075] The first hinge member 31 and the switching assembly 40 achieve relative movement through the mutually cooperating first shaft group 311, 312 and the first slot group 411, 412. The first shaft group 311, 312 includes a first shaft 311 and a second shaft 312. The first slot group 411, 412 includes a first free section S1, a second free section S2 and locking sections 4132, 4142, 4152, 4162. The first free section S1 includes a relatively set initial position A1 and a stop position A2. The second free section S2 includes a connected first section L1 and a second section L2.

[0076] The second hinge member 32 and the switching assembly 40 achieve relative movement through the second shaft group 321, 322 and the second slot group 421, 422 that cooperate with each other. The second shaft group 321, 322 includes a third shaft 321 and a fourth shaft 322. The second slot group 421, 422 includes a third free section 421, a fourth free section 4221 and a limiting section 4222.

[0077] When the door body 20 is in the closed state (see Figures 10 to 13 ), the first shaft 311 is located at the initial position A1, the second shaft 312 is located at one end of the first section L1 away from the second section L2, and the fourth shaft 322 is located at the limiting section 4222 so that the switching component 40 limits the second hinge 32.

[0078] When the door body 20 is in the process of opening from the closed state to the first opening angle α1 (refer to Figures 14 to 21 ), the second shaft 312 moves in the first section L1 and drives the first shaft 311 to move from the initial position A1 to the stop position A2, and the door body 20 moves from the pivot side P toward the accommodating chamber S, and then the second shaft 312 moves in the second section L2 and drives the first shaft 311 to move from the stop position A2 toward the initial position A1, and the door body 20 moves from the accommodating chamber S toward the pivot side P.

[0079] Specifically, when the door body 20 is in the process of opening from the closed state to the first intermediate opening angle α11 (refer to Figures 14 to 17 ), the second shaft 312 moves in the first section L1 to drive the first shaft 311 to move from the initial position A1 to the stop position A2, and the door body 20 moves from the pivot side P toward the accommodating chamber S.

[0080] Here, when the door body 20 is in the process of opening from a closed state to a first intermediate opening angle α11, the door body 20 moves toward one side of the accommodating chamber S, that is, at this time, the door body 20 both rotates relative to the box body 10 and is displaced along the first direction X relative to the box body 10. In this way, the distance that the door body 20 protrudes from the box body 10 toward the side away from the accommodating chamber S during the rotation process will be greatly reduced, that is, the displacement of the door body 20 along the first direction X offsets the part of the door body 20 protruding from the box body 10 along the second direction Y during the rotation of the door body 20, thereby avoiding interference between the door body 20 and surrounding cabinets or walls during the opening process, and is suitable for built-in cabinets or scenes with a small space for accommodating the refrigerator 100.

[0081] When the door body 20 is in the process of opening from the first intermediate opening angle α11 to the first opening angle α1 (refer to Figures 18 to 21 ), the second shaft 312 moves in the second section L2 to drive the first shaft 311 to move from the stop position A2 toward the initial position A1, and the door body 20 moves from the accommodating chamber S toward the pivot side P.

[0082] Here, when the door body 20 is in the process of opening from the first intermediate opening angle α11 to the first opening angle α1, the door body 20 moves toward one side of the pivot side P, that is, at this time, the door body 20 both rotates relative to the box body 10 and displaces along the second direction Y relative to the box body 10. In this way, the door body 20 can be kept as far away from the box body 10 as possible to ensure the opening degree of the box body 10 and avoid the problem that the drawers, shelves, etc. in the box body 10 are interfered by the door body 20 and cannot be opened.

[0083] 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 (see Figure 22 to Figure 25 ), the fourth shaft body 322 is disengaged from the limiting section 4222, and the first shaft body 311 and / or the second shaft body 312 is limited to the locking sections 4132, 4142, 4152, 4162 so that the switching assembly 40 limits the first hinge member 31.

[0084] 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 (see Figure 26 to Figure 29 ), the third shaft 321 rotates in place in the third free section 421, the fourth shaft 322 moves in the fourth free section 4221 with the third shaft 321 as the center, and the door body 20 continues to rotate in place relative to the box body 10.

[0085] Continue to combine Figures 1 to 9 The first hinge component 31 includes a first shaft 311 and a second shaft 322, the switching component 40 includes a first slot 411 with a first free section S1, a second slot 412 with a second free section S2, a third shaft 321 and a fourth shaft 322, and the second hinge component 32 includes a third slot 421 with a third free section 421 and a fourth slot 422 with a fourth free section 4221.

[0086] The switching assembly 40 includes a first switching member 401 and a second switching member 402 that cooperate with each other.

[0087] The first slot body 411 includes a first upper slot body 413 located at the first switching member 401 and a first lower slot body 414 located at the second switching member 402 . The first free section S1 includes a first upper free section 4131 located at the first upper slot body 413 and a first lower free section 4141 located at the first lower slot body 414 .

[0088] The second slot body 412 includes a second upper slot body 415 located at the first switching member 401 and a second lower slot body 416 located at the second switching member 402 . The second free section S2 includes a second upper free section 4151 located at the second upper slot body 415 and a second lower free section 4161 located at the second lower slot body 416 .

[0089] The locking sections 4132 , 4142 , 4152 , 4162 include a first upper locking section 4132 connected to the first upper free section 4131 , a first lower locking section 4142 connected to the first lower free section 4141 , a second upper locking section 4152 connected to the second upper free section 4151 , and a second lower locking section 4162 connected to the second lower free section 4161 .

[0090] The first upper locking segment 4132 and the first lower locking segment 4142 are always staggered with each other, and the second upper locking segment 4152 and the second lower locking segment 4162 are always staggered with each other.

[0091] Here, “always offset from each other” means that during the opening process of the door body 20, the first upper locking segment 4132 and the first lower locking segment 4142 will not be completely overlapped, and the second upper locking segment 4152 and the second lower locking segment 4162 will not be completely overlapped.

[0092] In this embodiment, the first switching member 401 is closer to the first hinge member 31 than the second switching member 402 , that is, the first hinge member 31 , the first switching member 401 , the second switching member 402 and the second hinge member 32 are stacked in sequence.

[0093] Combination Figure 5 and Fig. 9The hinge assembly 30 also includes a first rivet plate 4111 and a second rivet plate 4121. When the first shaft body 311 extends into the first groove body 411, the first rivet plate 4111 is located below the second switching member 402 and is sleeved on the first shaft body 311, thereby preventing the first shaft body 311 from detaching from the first groove body 411. Similarly, when the second shaft body 312 extends into the second groove body 412, the second rivet plate 4121 is located below the second switching member 402 and is sleeved on the second shaft body 312, thereby preventing the second shaft body 312 from detaching from the second groove body 412.

[0094] The first switching member 401 and the second switching member 402 are connected to each other via the fifth shaft 50 .

[0095] Here, the first switching member 401 and the second switching member 402 are provided with a first through hole 4014 and a second through hole 4024 , and an independent riveted member as the fifth shaft 50 passes through the first through hole 4014 and the second through hole 4024 .

[0096] Specifically, the fifth shaft 50 includes a rivet column 51 and a rivet column gasket 52. The end of the rivet column 51 with a larger size is located below the second through hole 4024, and the end of the rivet column 51 with a smaller size extends to the second through hole 4024 and the first through hole 4014 in sequence. The rivet column gasket 52 is located above the first through hole 4014 and cooperates with the rivet column 51 to lock the rivet column 51.

[0097] In this way, the first switching member 401 and the second switching member 402 can be matched with each other, that is, the relative movement of the first switching member 401 and the second switching member 402 can be achieved, and the first switching member 401 and the second switching member 402 will not be separated from each other.

[0098] It should be noted that the first through hole 4014 and the second through hole 4024 match the fifth shaft 50 , and the first switching member 401 rotates in situ relative to the second switching member 402 .

[0099] In other embodiments, a through hole can be set on one of the first switching member 401 and the second switching member 402, and a fifth axis 50 can be set on the other one, and the first switching member 401 and the second switching member 402 can be matched with each other through the cooperation of the fifth axis 50 and the through hole, but it is not limited to this.

[0100] In addition, the first switching member 401 includes a third shaft 321 , the second switching member 402 has a through hole 4026 , the third shaft 321 extends to the third slot 421 through the through hole 4026 , and the second switching member 402 includes a fourth shaft 322 , and the fourth shaft 322 extends to the fourth slot 422 .

[0101] Here, the size of the through hole 4026 can be larger than that of the third shaft 321, so that the third shaft 321 can move in the through hole 4026, and when the first switching member 401 and the second switching member 402 move relative to each other, the through hole 4026 and the third shaft 321 can be avoided from interfering with each other.

[0102] That is to say, the third shaft 321 and the fourth shaft 322 of this embodiment are located in different switching components, but the present invention is not limited thereto.

[0103] In this embodiment, combined with Figure 5 and Fig. 9 The first switching member 401 includes a first lining 4011, a first sliding piece 4012 and a first bushing 4013 stacked in sequence, and the second switching piece 402 includes a second lining 4021, a second sliding piece 4022 and a second bushing 4023 stacked in sequence.

[0104] Here, the first hinge member 31, the first lining 4011, the first sliding piece 4012, the first bushing 4013, the second lining 4021, the second sliding piece 4022, the second bushing 4023 and the second hinge member 32 are stacked in sequence from top to bottom.

[0105] The first lining 4011 , the first bushing 4013 , the second lining 4021 and the second bushing 4023 are made of plastic material, such as polyformaldehyde (POM).

[0106] The first sliding sheet 4012 and the second sliding sheet 4022 are made of metal, such as stainless steel or Q235 steel.

[0107] The outer contours of the first lining 4011, the first slide 4012 and the first bushing 4013 match each other, and the first lining 4011 and the first bushing 4013 cooperate with each other to clamp the first slide 4012 therebetween, and slots need to be set on the first lining 4011, the first slide 4012 and the first bushing 4013 to cooperate to form the first upper slot body 413, the second upper slot body 415 and the first through hole 4014.

[0108] Here, the first through hole 4014 can be formed by forming slots only on the first slide 4012 and the first bushing 4013, that is, the first through hole 4014 does not penetrate the first lining 4011. At this time, the fifth axis 50 extends from the bottom of the first switching member 401 to the first through hole 4011, and the first lining 4011 can cover the first through hole 4014 and the fifth axis 50 to improve the aesthetics.

[0109] The outer contours of the second lining 4021, the second slide 4022 and the second bushing 4023 match each other, and the second lining 4021 and the second bushing 4023 cooperate with each other to clamp the second slide 4022 therebetween, and slots need to be set on the second lining 4021, the second slide 4022 and the second bushing 4023 to cooperate to form the first lower slot body 414, the second lower slot body 416 and the second through hole 4024.

[0110] Here, the second through hole 4024 can be formed by forming slots only on the second lining 4021 and the second slide 4022, that is, the second through hole 4024 does not penetrate the second bushing 4023. At this time, the fifth shaft body 50 extends from the bottom of the second bushing 4023 to the second through hole 4024 and the first through hole 4011, and the second bushing 4023 can cover the second through hole 4024 and the fifth shaft body 50 to improve the aesthetics.

[0111] At this time, one end of the riveted column 51 of the fifth shaft body 50 can be limited in the second bushing 4023, further improving the matching effect of the second lining 4021, the second sliding piece 4022 and the second bushing 4023.

[0112] In this embodiment, the first switching member 401 also includes a first decorative sheet 4015 covering the periphery of the first lining 4011, the first slide 4012 and the first sleeve 4013, and the second switching member 402 also includes a second decorative sheet 4025 covering the periphery of the second lining 4021, the second slide 4022 and the second sleeve 4023, and the first decorative sheet 4015 and the second decorative sheet 4025 are separated from each other.

[0113] Here, “the first decorative sheet 4015 and the second decorative sheet 4025 are separated from each other” means that the first decorative sheet 4015 and the second decorative sheet 4025 are independent structures. When the first switching member 401 and the second switching member 402 move relative to each other, the first decorative sheet 4015 and the second decorative sheet 4025 will also move relative to each other.

[0114] In addition, the first decorative sheet 4015 of the present embodiment is in the shape of a "door", that is, the first decorative sheet 4015 only covers three side surfaces of the first switching member 401, which is convenient for the assembly of the first decorative sheet 4015, and a snap-fit ​​structure can be provided at these three side surfaces to achieve coordination with the first decorative sheet 4015. In the overlapping direction of the first switching member 401 and the second switching member 402, the width of the first decorative sheet 4015 is approximately equal to the sum of the thicknesses of the first lining 4011, the first slide 4012 and the first sleeve 4013.

[0115] Similarly, the second decorative sheet 4025 is in the shape of a "door", that is, the second decorative sheet 4025 only covers three side surfaces of the second switching member 402, which is convenient for the assembly of the second decorative sheet 4025, and a snap-fit ​​structure can be set at these three side surfaces to achieve coordination with the second decorative sheet 4025. In the overlapping direction of the first switching member 401 and the second switching member 402, the width of the second decorative sheet 4025 is roughly equal to the sum of the thicknesses of the second lining 4021, the second slide 4022 and the second sleeve 4023.

[0116] The first decorative sheet 4015 and the second decorative sheet 4025 may be made of ABS (Acrylonitrile Butdiene Styrene) plastic.

[0117] Next, the specific working process of the hinge assembly 30 is introduced.

[0118] In this embodiment, the box body 10 includes 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 S and a side wall 22 always sandwiched between the front wall 21 and the accommodating chamber S. There is a side edge 23 between the front wall 21 and the side wall 22.

[0119] Combination Figures 10 to 13 When the door body 20 is in a closed state, the first switching member 401 and the second switching member 402 are relatively stationary, the first upper free segment 4131 and the first lower free segment 4141 overlap to form a first free segment S1, the second upper free segment 4151 and the second lower free segment 4161 overlap to form a second free segment S2, the first shaft body 311 is located at the initial position A1, and the second shaft body 312 is located at one end of the first segment L1 away from the second segment L2.

[0120] Specifically, the outer side surface 13 and the side wall 22 are located in the same plane, which can ensure the smoothness of the appearance, improve the aesthetics, and facilitate the installation of the door body 20, but is not limited thereto.

[0121] Combination Figures 14 to 17 When the door body 20 is in the process of opening from a closed state to a first intermediate opening angle α11, the first switching member 401 and the second switching member 402 are relatively stationary, the first upper free segment 4131 overlaps with the first lower free segment 4141 to form a first free segment S1, the second upper free segment 4151 overlaps with the second lower free segment 4161 to form a second free segment S2, the second shaft body 312 moves in the first segment L1 and drives the first shaft body 311 to move from the initial position A1 to the stop position A2, and the door body 20 moves from the pivot side P toward the accommodating chamber S.

[0122] Here, the side edge 23 moves to the side of the outer surface 13 close to the accommodating chamber S, that is, the hinge assembly 30 drives the side edge 23 to move toward the side close to the accommodating chamber S. During the opening process of the door body 20, the side edge 23 protruding from the outer surface 13 can be avoided from interfering with surrounding cabinets or walls.

[0123] Here, in order to ensure the opening degree of the box body 10 as much as possible and avoid the problem that the drawers, shelves, etc. in the box body 10 cannot be opened due to interference from the door body 20, the side edge 23 moves toward the side close to the accommodating chamber S to the plane where the outer side surface 13 is located, and then the hinge assembly 30 drives the side edge 23 to move in the plane and gradually approach the accommodating chamber S.

[0124] That is to say, at this time, on the basis of ensuring that the side edge 23 does not protrude from the corresponding outer side surface 13, the side edge 23 is made as close to the outer side surface 13 as possible. In this way, the door body 20 can be prevented from interfering with surrounding cabinets or walls during the opening process, and the opening degree of the box body 10 can be guaranteed as much as possible.

[0125] Combination Figures 18 to 21 When the door body 20 is in the process of continuing to open from the first intermediate opening angle α11 to the first opening angle α1, the first switching member 401 and the second switching member 402 are relatively stationary, the first upper free section 4131 overlaps with the first lower free section 4141 to form a first free section S1, the second upper free section 4151 overlaps with the second lower free section 4161 to form a second free section S2, the second shaft body 312 moves in the second section L2 and drives the first shaft body 311 to move from the stop position A2 toward the initial position A1, and the door body 20 moves from the accommodating chamber S toward the pivot side P so that the side edge 23 remains on the side of the outer side surface 13 close to the accommodating chamber S.

[0126] Here, the side edge 23 moves in the plane where the outer side surface 13 is located and gradually approaches the accommodating chamber S.

[0127] It can be understood that when the door body 20 is in the process of continuing to open from the second intermediate opening angle α12 to the first opening angle α1, if the door body 20 rotates in place relative to the box body 10, the side edge 23 will gradually move toward the side close to the accommodating chamber S. At the same time, the door body 20 gradually moves closer to the accommodating chamber S. The door body 20 will hinder the opening of drawers, shelves, etc. in the box body 10, that is, it will reduce the opening degree of the box body 10.

[0128] The hinge assembly 30 of the present embodiment drives the side edge 24 to move within the plane where the outer surface 13 is located, so that the door body 20 can be moved as far away from the box body 10 as possible, ensuring the opening degree of the box body 10 and preventing the drawers, shelves, etc. in the box body 10 from being interfered with by the door body 20 and unable to be opened, and preventing the side edge 23 from protruding out of the outer surface 13 in the direction away from the accommodating chamber S.

[0129] It should be noted that when the door body 20 is in the process of opening from the closed state to the first opening angle α1, the fourth shaft body 322 is always limited in the limiting section 4222 so that the switching assembly 40 limits the second hinge member 32 .

[0130] In addition, during this process, since the first upper free segment 4131 and the first lower free segment 4141 always overlap to form the first free segment S1, and the second upper free segment 4151 and the second lower free segment 4161 always overlap to form the second free segment S2, that is, the movement trajectories of the first switching member 401 and the second switching member 402 are exactly the same, and the first shaft 311 moves in the first free segment S1, and at the same time, the second shaft 312 moves in the second free segment S2. During this process, the first switching member 401 and the second switching member 402 will never stagger with each other, that is, the first switching member 401 and the second switching member 402 remain relatively stationary, which can avoid the first upper free segment 4131 and the first lower free segment 4141 from being misaligned with each other, and at the same time avoid the second upper free segment 4151 and the second lower free segment 4161 from being misaligned with each other. In this way, it can be ensured 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 S2.

[0131] Combination Figure 22 to Figure 25 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 first switching member 401 and the second switching member 402 move relative to each other, causing the fourth shaft 322 to disengage from the limiting section 4222, and the first shaft 311 and / or the second shaft 312 are limited to the locking sections 4132, 4142, 4152, 4162, causing the switching assembly 40 to limit the first hinge member 31.

[0132] Here, "the first switching member 401 and the second switching member 402 move relative to each other so that the second hinge member 32 is disengaged from the limit of the switching component 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 component 40 limits the first hinge member 31" means that the switching component 40 and the second hinge member 32 move relative to each other so that there is no mutual limitation between the switching component 40 and the second hinge member 32, and the switching component 40 and the first hinge member 31 move relative to each other so that the switching component 40 and the first hinge member 31 are limited to each other.

[0133] In this embodiment, the first shaft body 311 is simultaneously limited to the first upper locking section 4132 and the first lower locking section 4142, the second shaft body 312 is simultaneously limited to 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, as described below:

[0134] 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 can no longer move relative to the first free section S1 and the second free section S2, and at this time, the first shaft body 311 is adjacent to the first upper locking section 4132 and the first lower locking section 4142, and the second shaft body 312 is adjacent to the second upper locking section 4152. The trajectories of the first upper locking section 4132 and the second upper locking section 4152 adapt to the movement paths of the first shaft body 311 and the second shaft body 312.

[0135] When the door body 20 continues to open on the basis of 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 applies a force to the third axis 321 and the fourth axis 322 through the third free section 4211 and the fourth limiting section 4222, and then the third axis 321 and the fourth axis 322 drive the first switching member 401 and the second switching member 402 to move.

[0136] Specifically, at this time, the first shaft body 311 is adjacent to the first upper locking section 4132, and the second shaft body 312 is adjacent to the second upper locking section 4152. The first switching member 401 can move 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. At the same time, the second switching member 402 moves a second angle relative to the first shaft body 311 with the fifth shaft body 50 as the center until the first shaft body 311 is limited in the second upper locking section 4152. During this process, the second shaft body 312 is always in contact with the second lower locking section 4162, and the second angle is greater than the first angle.

[0137] That is to say, the first switching member 401 and the second switching member 402 will both rotate a certain angle, and the rotation angle of the second switching member 402 is greater than the rotation angle of the first switching member 401 , and the first switching member 401 and the second switching member 402 will also generate relative motion and stagger with each other.

[0138] It is understandable that there is no specific order in the rotation process of the first switching member 401 and the second switching member 402. The two can rotate simultaneously. For example, the first switching member 401 and the second switching member 402 rotate synchronously within a certain rotation angle range, and then the first switching member 401 and the second switching member 402 are staggered with each other.

[0139] In actual operation, the first switching member 401 and the second switching member 402 drive the first slot body 411 and the second slot body 412 to rotate relative to the first shaft body 311 and the second shaft body 312 respectively, and the first shaft body 311 disengages from the first free section S1 and abuts against the first upper locking section 4132 and the first lower locking section 4142, that is, the first shaft body 311 is simultaneously limited to the first upper locking section 4132 and the first lower locking section 4142, and the second shaft body 312 disengages 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, and at the same time, the movement of the second switching member 402 causes the fourth shaft body 322 to disengage from the fourth limiting section 4222.

[0140] It can be understood that when the first shaft body 311 is located at the first upper locking segment 4132 and the first lower locking segment 4142, since the first switching member 401 and the second switching member 402 are staggered with each other, the first upper free segment 4131 and the first lower free segment 4141 that originally overlap with each other will also be staggered with each other. At this time, the staggered first upper free segment 4131 and the first lower free segment 4141 restrict the first shaft body 311 from being separated from the first upper locking segment 4132 and the first lower locking segment 4142, which can ensure that the first shaft body 311 always remains at the first upper locking segment 4132 and the first lower locking segment 4142 during the process of the door body 20 continuing to open.

[0141] 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 switching member 401 and the second switching member 402 are staggered with each other, the second upper free section 4151 and the second lower free section 4161 that originally overlap with each other will also be staggered with each other. At this time, the staggered second upper free section 4151 and the second lower free section 4161 restrict the second shaft body 312 from disengaging from the second upper locking section 4152 and the second lower locking section 4162, thereby ensuring that the second shaft body 312 always remains at the second upper locking section 4152 and the second lower locking section 4162 during the process of the door body 20 continuing to open.

[0142] In addition, the rotation angle of the second switching member 402 is greater than the rotation angle of the first switching member 401, that is, the second switching member 402 and the first switching member 401 are staggered with each other, which can further improve the locking effect between the first hinge member 31 and the switching assembly 40, ensuring that the first shaft body 311 always remains at the first upper locking section 4132 and the first lower locking section 4142, and the second shaft body 312 always remains at the second upper locking section 4152 and the second lower locking section 4162.

[0143] It should be noted that, in the present embodiment, the first upper locking section 4132 is the portion of the first upper free section 4131 close to the initial position A1. When the door body 20 is opened to the first opening angle α1, the first shaft body 311 moves from the stop position A2 toward the initial position A1 without reaching the initial position A1. 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 first shaft body 311 moves to the initial position A1 (i.e., moves to the first upper locking section 4132). At the same time, the second shaft body 312 moves to the first lower locking section 4142. During this process, the door body 20 actually continues to move from the accommodating chamber S toward the pivot side P.

[0144] Combination Figure 26 to Figure 29 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 first switching member 401 and the second switching member 402 are relatively stationary, the third shaft 321 moves in the third free section 421, and the fourth shaft 322 moves in the fourth free section 4221.

[0145] Here, the range of the first opening angle α1 is approximately 80°~83°, the second opening angle α2 is approximately 90°, and the maximum opening angle α3 is greater than 90°. That is to say, in the process of the door body 20 opening to 80°~83°, the door body 20 first displaces along the first direction X to avoid interference between the door body 20 and surrounding cabinets or walls during the opening process, and then the door body 20 displaces along the second direction Y to avoid the door body 20 hindering the opening of drawers, shelves, etc. in the box body 10, and finally reaches 80°~83°. Thereafter, in the process of the door body 20 continuing to open to 90°, the switching component 40 moves and causes the door body 20 to change the rotation axis and continue to rotate, that is, after 90°, the door body 20 continues to rotate in place relative to the box body 10 with the third axis 321 as the rotation axis to further open the door body 20.

[0146] It is to be understood that the angle is not limited to the above description.

[0147] It can be seen that in this embodiment, the unlocking and locking effects of the switching component 40 on the first hinge 31 and the second hinge 32 can effectively control the sequential switching of the first hinge 31 and the second hinge 32, so that the door body 20 can be stably opened.

[0148] It can be understood that when the door body 20 is in the process of closing, 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 31 and the second hinge 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 the switching component 40 locks the first hinge 31. 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 the switching component 40 locks the first hinge 31. When closing from the second opening angle α2 to the first opening angle α1, the first switching member 401 and the second switching member 402 move relative to each other so that the first hinge member 31 is disengaged from the limit of the switching component 40, and the fourth shaft 322 is limited to the fourth limit section 4222. The switching component 40 locks the second hinge member 32. When the door body 20 is in the process of closing from the first opening angle α1 to being fully closed, the first shaft 311 moves in the first free section S1, and the second shaft 312 moves in the second free section S2.

[0149] In other words, the closing process of the door body 20 is a process in the opposite order to the opening process of the door body 20. By unlocking and locking the first hinge 31 and the second hinge 32 by the switching component 40, the switching order of the first hinge 31 and the second hinge 32 during the opening and closing process of the door body 20 can be effectively controlled.

[0150] In this embodiment, the first distance is between the center of the first axis 311 and the side edge 23, the second distance is between the center of the first axis 311 and the front wall 21, the third distance is between the center of the first axis 311 and the side wall 22, the fourth distance is between the center of the third axis 312 and the side edge 23, the fifth distance is between the center of the third axis 312 and the front wall 21, and the sixth distance is between the center of the third axis 312 and the side wall 22. When the door body 20 is in the process of opening from a closed state to a first opening angle α1, the first distance, the second distance and the third distance all show a decreasing trend first and then an increasing trend. 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 fourth distance, the fifth distance and the sixth distance all remain unchanged.

[0151] In addition, in this embodiment, the first axis 311 and the third axis 321 are staggered with each other, so it can be suitable for built-in cabinets or scenes with a small space for accommodating the refrigerator 100.

[0152] Combination Fig.30 , taking a simple schematic diagram of a refrigerator 100 embedded in a cabinet 200 as an example for explanation.

[0153] In this embodiment, 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 S 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 S and a side wall 22 always sandwiched between the front wall 21 and the accommodating chamber S, and a side edge 23 is provided between the front wall 21 and the side wall 22.

[0154] Here, when the door body 20 is in the process of being opened from a closed state to a first opening angle α1, the door body 20 rotates around the first axis 311, and a first distance is provided between the first axis 311 and the front end face 103. 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 door body 20 rotates around the third axis 321, and a second distance is provided between the third axis 321 and the front end face 103. The second distance is greater than the first distance. In this way, the maximum opening angle of the fully embedded refrigerator 100 can be greatly improved.

[0155] In addition, there is a third distance between the first axis 311 and the outer side surface 13. 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, there is a fourth distance between the third axis 321 and the outer side surface 13. The fourth distance is smaller than the third distance, which can further increase the opening degree of the box body 10.

[0156] The specific instructions are as follows:

[0157] In certain movement trajectories of the refrigerator 100, the first axis 311 and the third axis 321 will move relative to the door body 20, or the hinge assembly 30 also includes a second axis 312 cooperating with the first axis 311 and a fourth axis 322 cooperating with the third axis 321. To simplify the description, it is simply considered that the door body 20 first rotates around the first axis 311, and then switches to rotation around the third axis 321 through the switching assembly 40.

[0158] In actual operation, in order to improve the embedding effect, it is better to make the refrigerator 100 completely embedded in the cabinet 200, and 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 located 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.

[0159] 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 Fig.30In 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 gap between the inner wall 202 of the cabinet 200 and the refrigerator 100. The gap needs to be about 10 cm, which will seriously affect the embedding effect and is not conducive to the rational use of limited space.

[0160] Combination Fig.30 , the shaded area represents the door body 20 in the closed state. When the door body 20 is in the process of opening, if the door body 20 always rotates around the first shaft body 311 (i.e., the prior art), refer to Fig.30 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 corner 203 of the cabinet 200 will interfere with the door body 20' and limit the maximum opening angle of the door body 20'.

[0161] In the present embodiment, the third shaft 321 is located on the first switching member 401. When the door 20 is opened, the switching assembly 40 moves relative to the first hinge member 31 and the second hinge member 32, so that the third shaft 321 gradually moves away from the front end surface 103, that is, the third shaft 321 gradually moves toward the front end 201 of the cabinet 200. That is, at this time, the entire door 20 moves in the direction away from the box body 10. Fig.30 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. The corners 203 of the cabinet 200 will interfere with each other only when the door body 20 is opened to a larger angle, thereby greatly improving the maximum opening angle of the door body 20.

[0162] That is to say, in this embodiment, the switching component 40 can be used to enable the door body 20 to rotate around the third axis 321. On 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 facilitating the user to operate the refrigerator 100 and greatly improving the user experience.

[0163] Moreover, the present embodiment does not need to increase the gap 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.

[0164] In addition, the switching component 40 of the present embodiment drives the third axis 321 to gradually move toward the front end 201 of the cabinet 200, while also driving the third axis 321 to gradually approach the inner wall 202 of the cabinet 200. That is to say, 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 degree of the box body 10, so as to facilitate the opening and closing of shelves, drawers, etc. in the box body 10, or to facilitate the taking and placing of items.

[0165] Of course, the third axis 321 which ultimately serves as the rotation axis may 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 from the inner wall 202 of the cabinet 200 than the first axis 311, and so on.

[0166] It can be understood that the switching 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.

[0167] In addition, it should be noted that the movement trajectory of the door body 20 can be effectively controlled through the specific design of the shaft body groove. In the present embodiment, the box 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 at least drives the door body 20 to move from the pivot side P toward the accommodating chamber S, thereby avoiding interference between the door body 20 and surrounding cabinets or walls during the opening process. The specific design of the shaft body groove can refer to the following embodiment.

[0168] In this embodiment, the structures of the hinge assemblies 30 located in different areas of the door body 20 are different. The hinge assembly 30 is located above the door body 20 and between the box body 10. Fig.31 and Fig.32 , briefly introduce the hinge assembly 30 ′ located between the lower side of the door body 20 and the box body 10 .

[0169] The difference between the lower hinge assembly 30' and the upper hinge assembly 30 is that the first hinge part 31' of the lower hinge assembly 30' has a protrusion 313', and the second hinge part 32' has a corresponding hook 323', the hook 323' is an elastic part, when the door body 20 is in a closed state, the protrusion 313' acts on the hook 323' to deform so that the door body 20 and the box body 10 fit closely, when the door body 20 is in the opening process, the door body 20 drives the hook 323' to move, the hook 323' is deformed and separates from the protrusion 313'.

[0170] That is to say, when the door body 20 is in a closed state, there is an interference fit between the protrusion 313 ′ and the hook 323 ′, which enhances the closing effect of the door body 20 .

[0171] It should be noted that, since the switching component 40' is connected between the first hinge member 31' and the second hinge member 32', the second hinge member 32' also includes an extension section 324' passing through the switching component 40' along the thickness direction, and the extension section 324' is connected to the hook 323', so that the hook 323' can be horizontally arranged and can be adapted to the protrusion 313'.

[0172] In this embodiment, combined with Figure 33 to Figure 36 , the refrigerator 100 is a refrigerator 100 with a wiring module 60.

[0173] The wiring module 60 includes a fixed end 61 and a free end 62 that are relatively arranged. The fixed end 61 is connected to the door body 20, and the free end 62 is movably arranged on the box body 10. The wiring E of the box body 10 passes through the free end 62 and the fixed end 61 in sequence and extends to the door body 20.

[0174] Here, “the free end 62 is movably disposed on the box body 10” means that the free end 62 is not fixed to the box body 10, and as the door body 20 opens, the free end 62 can move relative to the box body 10, thereby allowing the wiring E located in the wiring module 60 to move freely as the door body 20 opens.

[0175] It should be noted that, as the refrigerator 100 becomes more intelligent and multifunctional, some functional modules are usually arranged on the door body 20 of the refrigerator 100, such as an ice-making module, a display module, etc. These modules usually need to be connected to the control module in the cabinet 10 through the wiring E. The wiring E of this embodiment is extended to the door body 20 through the wiring module 60, which can effectively avoid the phenomenon of the wiring E being pulled during the opening and closing process of the door body 20, and can adapt to various movement trajectories of the door body 20. For example, when the hinge assembly 30 drives the door body 20 to move from the pivot side P toward the accommodating chamber S, the extension trajectory of the wiring E will also change. The design of the wiring module 60 in this embodiment can fully adapt to this movement of the door body 20, that is, the extension trajectory of the wiring E can be flexibly adjusted through the wiring module 60 to avoid wire jamming.

[0176] In this embodiment, the refrigerator 100 also includes a limited space 101, which includes a slot 1011 set toward the door body 20. The fixed end 61 of the wiring module 60 passes through the slot 1011 and is connected to the door body 20. When the door body 20 is in the opening process, the door body 20 drives the wiring module 60 to move in the limited space 101, and the free end 62 is always located in the limited space 101.

[0177] Here, the limiting space 101 is located at the top 11 of the box 10, the wiring module 60 is arranged parallel to the top 11 of the box 10, and the fixed end 61 is movably connected to the door body 20. Of course, the limiting space 101 can also be arranged in other areas.

[0178] Specifically, in this embodiment, the routing module 60 includes a first shell 601 and a second shell 602. The second shell 602 is arranged adjacent to the top 11 of the box body 10. The first shell 601 is away from the top 11 of the box body 10 relative to the second shell 602. The first shell 601 and the second shell 602 cooperate with each other to form a accommodating cavity 603 for accommodating the routing E. The two end openings of the accommodating cavity 603 are a fixed end 61 and a free end 62.

[0179] The door body 20 protrudes upward from the top 11 of the box body 10, and a stopper 111 protruding from the top 11 is provided at the edge of the top 11 near the door body 20, and a slot 1011 is opened at the stopper 111. The refrigerator 100 includes a plurality of protrusions 112 protruding from the top 11, and the plurality of protrusions 112 are surrounded to form a limited space 101.

[0180] Here, the first hinge component 31 is fixed to the edge position of the top 11, and in order to adapt to the design of the door body 20 protruding from the top 11, the first hinge component 31 of the hinge assembly 30 is roughly Z-shaped, so that the first hinge component 31 can extend from the top 11 of the box body 10 to the top of the door body 20 and adapt to the switching assembly 40 located at the top of the door body 20, and the plurality of protrusions 112 include a first protrusion 1121 located between the first hinge component 31 and the routing module 60 and a second protrusion 1122 spaced apart from the first protrusion 1121. The first protrusion 1121 can avoid mutual interference between the routing module 60 and the first hinge component 31, and the contour of the first protrusion 1121 is adapted to the movement trajectory of the routing module 60. The second protrusion 1122 can be a plurality of convex columns to reduce the collision between the routing module 60 and the second protrusion 1122.

[0181] The refrigerator 100 may further include a cover 103, which is located at the top 11 and covers the limiting space 101, the first hinge 31, etc. The cover 103 may be compatible with the stopper 111, and the shape of the cover 103 may be determined according to specific needs.

[0182] In addition, the fixed end 61 and the slot 1011 of the wiring module 60 are both arranged close to the hinge assembly 30. It can be understood that during the opening process of the door body 20, the wiring module 60 will be exposed in the opening gap of the door body 20. By setting the fixed end 61 and the slot 1011 close to the hinge assembly 30, on the one hand, the movement trajectory of the wiring module 60 can be reasonably controlled, and on the other hand, the wiring module 60 can be prevented from affecting the appearance and normal use of the refrigerator 100.

[0183] The wiring module 60 is horizontally arranged and extends to the door body 20 through the slot 1011. A wiring hole H is provided in the door body 20. The wiring E extends out from the fixed end 61 and extends from the wiring hole H to the inside of the door body 20. The area C adjacent to the wiring hole H is pivotally connected to the fixed end 61 area, and the door body 20 includes a cover body 24 covering the fixed end 61, the wiring hole H and the area C. In this way, the wiring module 60 and the door body 20 can be movably connected. When the door body 20 is in the process of opening, the door body 20 drives the wiring module 60 to move, and the wiring module 60 can move freely along different trajectories in the limited space 101. That is to say, the movement trajectory of the wiring module 60 can fully adapt to the movement trajectory of the door body 20, thereby avoiding wire jamming.

[0184] In addition, the wiring module 60 includes an arc segment D, which can further prevent the wiring E from being disturbed inside the accommodating cavity 603 .

[0185] It should be noted that in order to avoid wear and sliding noise of the routing module 60, a buffer component or a sliding component may be provided between the second shell 602 of the routing module 60 and the top 11 of the box 10, and the specific configuration may be determined according to actual conditions.

[0186] In this embodiment, the slot 1011 of the limiting space 101 has a first slot width, the routing module 60 includes a movable portion 63 located between the fixed end 61 and the free end 62 , and the first slot width is greater than the maximum width of the movable portion 63 .

[0187] That is to say, as the door body 20 opens, the movable part 63 gradually protrudes out of the limiting space 101, and the width of the first slot is greater than the maximum width of the movable part 63, which can prevent the slot 1011 from restricting the movable part 63 from protruding out of the limiting space 101, and the slot 1011 can control the movement trajectory of the routing module 60 to a certain extent, preventing the routing module 60 from moving too much and leaving the limiting space 101.

[0188] Here, in order to further prevent the wiring module 60 from being separated from the limiting space 101 , the free end 62 may be configured to be bent, that is, an angle is formed between the free end 62 and the movable portion 63 .

[0189] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention is described in detail with reference to the preferred embodiments, for example, if the techniques in different embodiments can be used in a superimposed manner to achieve corresponding effects at the same time, the 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 can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
