Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of refrigeration equipment, and in particular to a refrigerator. Background Art

[0002] A refrigerator includes a housing, a door, and a hinge. The housing forms a storage chamber for accommodating food or other items. The door is movably mounted on the housing via a hinge to close or open the storage chamber. The hinge is typically mounted on a crossbeam of the housing.

[0003] In the related art, the hinge includes a six-link structure. When the refrigerator needs to be embedded in a cabinet, the hinge can control the door body to bypass the edge of the cabinet during the opening process to avoid interference between the door body and the cabinet during the opening process, and to avoid the door body blocking the storage room.

[0004] However, the hinges in these refrigerators are thicker along the height of the refrigerator, increasing the length of the crossbeams along the height of the refrigerator. This is particularly true of the center crossbeams in cross-door refrigerators, which are longer due to the hinges for the upper and lower doors. While the dimensions of the refrigerator remain unchanged, this increased crossbeam length reduces the available height of the storage compartment, thereby reducing the refrigerator's capacity. Utility Model Content

[0005] An embodiment of the present application provides a refrigerator that can solve the technical problem of large hinge thickness in related refrigerators.

[0006] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0007] The box body is configured with a storage chamber with a front opening;

[0008] The door body is rotatably arranged relative to the box body to open and close the storage chamber;

[0009] Hinges are provided on the box body and the door body respectively, and are used to rotate the door body relative to the box body; the hinges include:

[0010] A mounting base, arranged on the box body;

[0011] The swing arm is arranged on the door body;

[0012] a first connecting rod, a first end of which is pivotally connected to the mounting base;

[0013] a second connecting rod, a first end of which is pivotally connected to the swing arm, and a second end of which is pivotally connected to the second end of the first connecting rod;

[0014] a third connecting rod, a first end of which is pivotally connected to the mounting base, the first end of the third connecting rod being farther away from the front wall of the box than the first end of the first connecting rod, and a second end of the third connecting rod being pivotally connected to the second connecting rod;

[0015] a fourth connecting rod, a first end of which is pivotally connected to the swing arm, the first end of the fourth connecting rod being closer to the hinge end of the door body than the first end of the second connecting rod, and a second end of the fourth connecting rod being pivotally connected to the third connecting rod;

[0016] a cam member, disposed at an end of the second connecting rod close to the first connecting rod;

[0017] A cam assembly is provided on the first connecting rod, and when the hinge is closed, the cam assembly elastically presses against the cam member, and the elastic force of the cam assembly on the cam member has a torque that causes the first end of the second connecting rod to rotate toward the first connecting rod;

[0018] Among them, the second connecting rod has a second connecting rod groove, the second end of the third connecting rod is arranged in the second connecting rod groove, and at least part of the cam member is arranged in the second connecting rod groove; the third connecting rod has a third connecting rod groove, the cam member is located outside the third connecting rod groove, and the length of the cam member along the height direction of the box body is greater than the length of the third connecting rod groove along the height direction.

[0019] In the refrigerator of the embodiment of the present application, when the length of the cam member along the height direction of the cabinet is constant, the cam member is disposed only in the second connecting rod groove and outside the third connecting rod groove, eliminating the need for a cam member in the third connecting rod groove. Thus, the length of the third connecting rod groove along the height direction of the cabinet can be less than the length of the cam member along the height direction of the cabinet, thereby reducing the length of the third connecting rod groove along the height direction of the cabinet, and thereby reducing the thickness of the hinge. Since the hinge is disposed on the crossbeam of the cabinet, the thickness of the hinge is reduced, and the length of the crossbeam along the height direction of the cabinet can be correspondingly reduced. Given a constant cabinet height, the available height of the storage compartment can be increased, thereby increasing the capacity of the refrigerator.

[0020] In some embodiments of the present application, the second link and the first link are pivotally connected via a first pivot axis;

[0021] The first pivot shaft is disposed on the cam member;

[0022] The second connecting rod is configured with a fixing portion, and the cam member is configured with a matching portion. The matching portion and the fixing portion cooperate to limit the cam member from rotating relative to the second connecting rod.

[0023] With this arrangement, the matching portion and the fixing portion cooperate to limit the cam member from rotating relative to the second connecting rod, thereby improving the stability of the cam member and the cam assembly when they are elastically matched.

[0024] In some embodiments of the present application, the fixing portion includes a limiting hole, and the matching portion is inserted into the limiting hole.

[0025] With this arrangement, the matching portion is inserted into the limiting hole, so that the cam member is not easily rotated relative to the second connecting rod. During the opening and closing process of the hinge, the cam member and the second connecting rod can achieve synchronous rotation.

[0026] In some embodiments of the present application, the thickness of the first end of the first connecting rod is smaller than the thickness of the second end of the first connecting rod, and the first end of the first connecting rod is nested in the mounting seat.

[0027] This arrangement reduces the length of the entire assembly formed by assembling the first connecting rod and the mounting seat along the height direction of the box body, thereby reducing the thickness of the hinge.

[0028] In some embodiments of the present application, the first connecting rod has a top surface and a bottom surface along the height direction of the box body, and the top surface and the bottom surface of the first end of the first connecting rod are recessed toward each other.

[0029] This arrangement reduces the length of the first end of the first connecting rod along the height direction of the box, thereby reducing the length of the mounting base adapted to mate with the first end of the first connecting rod along the height direction of the box. Because the mounting base is located at the outermost portion of the hinge, reducing the length of the mounting base along the height direction of the box can reduce the length of the entire hinge along the height direction of the box, thereby reducing the thickness of the hinge.

[0030] In some embodiments of the present application, the mounting seat has a reinforced flange, which is folded in a direction away from the front wall of the box.

[0031] With such a configuration, the reinforced flange can improve the structural strength of the mounting seat and prevent the mounting seat from being deformed.

[0032] In some embodiments of the present application, the reinforcing flange includes a first reinforcing flange and a second reinforcing flange, and the first reinforcing flange and the second reinforcing flange are spaced apart along the height direction of the box body;

[0033] When the hinge is closed, the reinforcing flange is spaced apart from the end of the front wall of the box and the end of the first connecting rod away from the swing arm, and the spacing between the first reinforcing flange and the second reinforcing flange is not greater than the thickness of the end of the first connecting rod away from the swing arm.

[0034] With such an arrangement, since the first connecting rod does not need to be accommodated between the first reinforcing flange and the second reinforcing flange, the length of the interval between the first reinforcing flange and the second reinforcing flange in the height direction of the box body does not need to be increased according to the length of the first connecting rod in the height direction of the box body. The interval between the first reinforcing flange and the second reinforcing flange can be less than or equal to the thickness of the end of the first connecting rod away from the swing arm. Compared with the implementation method of nesting the end of the first connecting rod away from the swing arm in the mounting seat, the embodiment of the present application reduces the length of the mounting seat in the height direction of the box body when the length of the first connecting rod in the height direction of the box body is constant. Since the mounting seat is located at the outermost part of the hinge, the reduction in the length of the mounting seat in the height direction of the box body can reduce the length of the entire hinge in the height direction of the box body, thereby reducing the thickness of the hinge.

[0035] In some embodiments of the present application, when the hinge is closed, the distance between the end of the reinforcing flange facing away from the front wall and the end of the first connecting rod close to the front wall along the depth direction of the refrigerator is greater than 0 and less than or equal to 2 mm.

[0036] Such an arrangement can not only ensure the structural strength of the mounting seat, but also reduce the interference between the first connecting rod and the mounting seat during the opening and closing of the hinge, thereby reducing the possibility of interference between the first connecting rod and the mounting seat due to assembly errors.

[0037] In some embodiments of the present application, the protruding rod assembly includes:

[0038] Fixed parts, including:

[0039] A fixed seat, fixedly arranged on the first connecting rod;

[0040] A first rod is disposed on a fixing seat;

[0041] Sliding components, including:

[0042] The sliding seat is arranged to slide relative to the first connecting rod.

[0043] A second rod is disposed on the sliding seat, and the second rod is slidably disposed relative to the first rod;

[0044] An abutment member is provided on the sliding seat, and the abutment member and the cam member are pressed and fitted;

[0045] The elastic member is arranged between the fixed seat and the sliding seat in a compressed state.

[0046] With such arrangement, under the action of the elastic force of the elastic member, the sliding seat drives the abutment member to slide relative to the first connecting rod, so that the abutment member can elastically abut against the cam member during the rotation of the door body.

[0047] In some embodiments of the present application, the abutment member includes a roller, and the roller is arranged to roll relative to the sliding seat.

[0048] With this arrangement, when the abutment member and the cam member are pressed together, the contact area between the abutment member and the cam member is reduced, thereby reducing the friction between the abutment member and the cam member, thereby reducing the friction noise generated when the abutment member and the cam member are pressed together.

[0049] In some embodiments of the present application, the first connecting rod is configured with a slideway;

[0050] The sliding component further comprises a sliding rod, which is arranged on the sliding seat and slidably arranged on the slideway.

[0051] Such arrangement enables the sliding seat to slide relative to the first connecting rod along the extending direction of the slideway.

[0052] In a second aspect, an embodiment of the present application provides a refrigerator, comprising:

[0053] The box body is configured with a storage chamber with a front opening;

[0054] The door body is rotatably arranged relative to the box body to open and close the storage chamber;

[0055] Hinges are provided on the box body and the door body respectively, and are used to rotate the door body relative to the box body; the hinges include:

[0056] A mounting base, arranged on the box body;

[0057] The swing arm is arranged on the door body;

[0058] a first connecting rod, a first end of which is pivotally connected to the mounting base;

[0059] a second connecting rod, a first end of which is pivotally connected to the swing arm, and a second end of which is pivotally connected to the second end of the first connecting rod;

[0060] a third connecting rod, a first end of which is pivotally connected to the mounting base, the first end of the third connecting rod being farther away from the front wall of the box than the first end of the first connecting rod, and a second end of the third connecting rod being pivotally connected to the second connecting rod;

[0061] a fourth connecting rod, a first end of which is pivotally connected to the swing arm, the first end of the fourth connecting rod being closer to the hinge end of the door body than the first end of the second connecting rod, and a second end of the fourth connecting rod being pivotally connected to the third connecting rod;

[0062] a cam member, disposed at an end of the second connecting rod close to the first connecting rod;

[0063] A cam assembly is provided on the first connecting rod, and when the hinge is closed, the cam assembly elastically presses against the cam member, and the elastic force of the cam assembly on the cam member has a torque that causes the first end of the second connecting rod to rotate toward the first connecting rod;

[0064] The second connecting rod has a second connecting rod groove, the second end of the third connecting rod is disposed in the second connecting rod groove, at least a portion of the cam member is disposed in the second connecting rod groove, and the cam member is located outside the third connecting rod;

[0065] The second connecting rod and the first connecting rod are pivotally connected via a first pivot shaft, and the first pivot shaft is arranged on the cam member; the second connecting rod is configured with a fixing portion, and the cam member is configured with a matching portion, and the matching portion is fixedly matched with the fixing portion.

[0066] In the refrigerator of the embodiment of the present application, the cam member is disposed within the second connecting rod groove via the first pivot axis and the fixing portion. This eliminates the need to partially nest the cam member within the third connecting rod to secure the cam member. The length of the third connecting rod along the height of the housing does not need to be increased based on the length of the cam member along the height of the housing. Thus, when the length of the cam member along the height of the housing remains constant, the length of the third connecting rod along the height of the housing is reduced, thereby reducing the thickness of the hinge. Because the hinge is disposed on the crossbeam of the housing, the thickness of the hinge is reduced, and the length of the crossbeam along the height of the housing can be reduced accordingly. When the height of the housing remains constant, the available height of the storage compartment can be increased, thereby increasing the capacity of the refrigerator.

[0114] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0115] It should be noted that the brief descriptions of terms in this application are only for the purpose of facilitating the understanding of the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and usual meanings.

[0116] In addition, the terms "comprises" and "comprising" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0117] In the description of this application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0118] The terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first," "second," or "third" may explicitly or implicitly include one or more of such features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0119] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense.

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0120] To address the technical issue of thick hinges in related refrigerators, the refrigerator of the present application embodiment, when the length of the cam member along the height direction of the cabinet is constant, is configured such that the cam member is disposed only in the second connecting rod groove and outside the third connecting rod groove, eliminating the need for a cam member in the third connecting rod groove. This allows the length of the third connecting rod groove along the height direction of the cabinet to be less than the length of the cam member along the height direction of the cabinet, thereby reducing the length of the third connecting rod groove along the height direction of the cabinet and, in turn, reducing the thickness of the hinge. Since the hinge is disposed on the crossbeam of the cabinet, the thickness of the hinge is reduced, and the length of the crossbeam along the height direction of the cabinet can be reduced accordingly. Given a constant cabinet height, the available height of the storage compartment can be increased, thereby increasing the capacity of the refrigerator.

[0121] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0122] It should be noted that the "front side" in the embodiments of the present application refers to the side of the refrigerator facing the user when the refrigerator is in normal use. The "rear side" refers to the side opposite the front side, that is, the side facing away from the user when the refrigerator is in normal use. The "left side" refers to the side on the user's left hand side when the refrigerator is in normal use. The "right side" refers to the side on the user's right hand side when the refrigerator is in normal use.

[0123] The "thickness" in the embodiments of the present application refers to the length along the height direction of the refrigerator.

[0124] refer to Figure 1 The refrigerator of the embodiment of the present application includes a housing 10. The housing 10 has a storage chamber 110, which is used to accommodate food or other items.

[0125] refer to Figure 2 A take-in / put-out opening 111 is formed at the front of the storage chamber 110 , and items can be taken out of the storage chamber 110 or placed into the storage chamber 110 through the take-in / put-out opening 111 .

[0126] The number of storage chambers 110 may be one or more. Figure 2 , the number of the storage chambers 110 can be three. One of the storage chambers 110 can be located at the upper portion of the box body 10. The other two storage chambers 110 can be located at the lower portion of the box body 10.

[0127] The storage chamber 110 may be configured as a refrigerator or a freezer. Figure 2 The storage chamber 110 located at the upper portion of the box body 10 can be set as a refrigeration chamber. The two storage chambers 110 located at the lower portion of the box body 10 can be set as freezer chambers.

[0128] It is understandable that in some possible implementations, the storage chamber 110 may also be configured as a variable temperature chamber with varying internal temperature, which will not be elaborated in the embodiments of the present application.

[0129] The front side of the box body 10 may have a crossbeam, which extends substantially along the width direction X of the box body 10. The crossbeam can support the box body 10 to improve the stability of the overall structure of the refrigerator and reduce the possibility of deformation or damage to the refrigerator.

[0140] In some embodiments, the door body 20 may include a sealing strip, which is provided on the door rear wall 201 of the door body 20. When the door body 20 closes the storage chamber 110, the sealing strip fits against the front side of the box body 10 to reduce cold air leakage from the storage chamber 110.

[0141] The sealing strip may be annular, and a portion of the sealing strip may fit with the crossbeam to improve the sealing effect of the storage chamber 110 .

[0142] In some embodiments, the refrigerator may further include a refrigeration device.

[0143] A refrigeration device may be provided in the housing 10 . The refrigeration device may be a refrigeration device known in the related art. The refrigeration device is used to provide cold air to the storage chamber 110 to reduce the temperature in the storage chamber 110 .

[0144] In some embodiments, reference Figure 1 The refrigerator may further include a hinge 30. The door body 20 is hingedly connected to the cabinet 10 via the hinge 30. The hinge 30 allows the door body 20 to rotate relative to the cabinet 10, thereby allowing the door body 20 to open and close the storage chamber 110.

[0155] The third link 350 may have a second end 352. The second end 352 and the first end 351 of the third link 350 are respectively located at two ends of the extension direction of the third link 350. The second end 352 of the third link 350 is pivotally connected to the second link 340.

[0156] refer to Figure 6 , the hinge 30 may further include a fourth link 360 .

[0157] The fourth link 360 may have a first end 361 that is pivotally connected to the swing arm 320. The first end 361 of the fourth link 360 is closer to the hinge end 210 of the door body 20 than the first end 341 of the second link 340.

[0158] The fourth link 360 may further include a second end 362. The second end 362 and the first end 361 of the fourth link 360 are respectively located at two ends of the extension direction of the fourth link 360. The second end 362 of the fourth link 360 is pivotally connected to the third link 350.

[0159] The fourth link 360 can be nested outside of a portion of the third link 350. The second link 340 can be nested outside of a portion of the third link 350. The mounting base 310 can be nested outside of a portion of the first link 330. The mounting base 310 can also be nested outside of a portion of the third link 350. The swing arm 320 can be nested outside of a portion of the second link 340. The swing arm 320 can also be nested outside of a portion of the fourth link 360.

[0160] That is, the third link 350 is located at the innermost part of the hinge 30 , the second link 340 and the fourth link 360 are located outside the third link 350 , and the mounting base 310 and the swing arm 320 are located at the outermost part of the hinge 30 to reduce the thickness of the hinge 30 .

[0161] refer to Figure 6 The hinge 30 may further include a cam member 370. The cam member 370 may be disposed at an end of the second link 340 that is close to the first link 330, or in other words, the cam member 370 may be disposed at the second end 342 of the second link 340. For example, the second end 342 of the second link 340 and the second end 332 of the first link 330 may be pivotally connected via a first pivot shaft 371, and the axis of the first pivot shaft 371 may be substantially parallel to the height direction Z of the box body 10.

[0162] The first pivot shaft 371 may be disposed on the cam member 370 .

[0163] In some embodiments, the cam member 370 may be configured with a mounting hole, the first pivot shaft 371 may be inserted into the mounting hole, the first pivot shaft 371 may be fixed to the cam member 370, or the first pivot shaft 371 and the cam member 370 may be integrally formed.

[0164] refer to Figure 5 and Figure 6 The second connecting rod 340 may further be configured with a fixing portion 344 , and the cam member 370 may be configured with a matching portion 372 , wherein the matching portion 372 cooperates with the fixing portion 344 to limit the cam member 370 from rotating relative to the second connecting rod 340 .

[0165] In some embodiments, reference Figure 5 and Figure 6 The fixing portion 344 may include a limiting hole, and the matching portion 372 may be block-shaped or columnar. The matching portion 372 is inserted into the limiting hole so that the cam member 370 is not easy to rotate relative to the second connecting rod 340. During the opening and closing process of the hinge 30, the cam member 370 and the second connecting rod 340 can achieve synchronous rotation.

[0166] In other embodiments, the fixing portion 344 may be block-shaped or column-shaped, and the matching portion 372 may be a matching hole, in which the fixing portion 344 is inserted so that the cam member 370 is not easily rotated relative to the second connecting rod 340. During the opening and closing process of the hinge 30, the cam member 370 and the second connecting rod 340 can achieve synchronous rotation.

[0167] In some embodiments, reference Figure 6The hinge 30 may further include a cam assembly 380. The cam assembly 380 is provided on the first connecting rod 330. The cam assembly 380 is elastic and elastically presses against the cam member 370 when the hinge 30 is closed. The elastic force of the cam assembly 380 on the cam member 370 has a torque that causes the first end 341 of the second connecting rod 340 to rotate toward the first connecting rod 330, making it difficult for the first end 341 of the second connecting rod 340 to rotate away from the first connecting rod 330. In other words, the external force required to open the hinge 30 from a closed state is increased, thereby increasing the locking force of the hinge 30 on the door body 20 and reducing the possibility of the door body 20 slipping open.

[0168] In some embodiments, reference Figure 7 and Figure 8 , the second connecting rod 340 may have a second connecting rod groove 343 .

[0169] For example, the second link 340 may include a first plate 345 , and the first plate 345 may extend substantially in a horizontal direction.

[0170] The second connecting rod 340 may include a second plate 346 , which may extend substantially in the horizontal direction. The second plate 346 and the first plate 345 may be disposed opposite each other and spaced apart from each other along the height direction Z of the box 10 .

[0171] The second connecting rod 340 may include a third plate 347, which may extend generally vertically. The third plate 347 is connected between the first plate 345 and the second plate 346 to form the second connecting rod 340. This third plate 347 not only connects the first plate 345 and the second plate 346 but also enhances the structural strength of the second connecting rod 340. The third plate 347, the first plate 345, and the second plate 346 together form the second connecting rod slot 343.

[0172] The second end 352 of the third link 350 can be disposed in the second link groove 343 to reduce the overall length of the third link 350 and the second link 340 after assembly along the height direction Z of the box body 10, thereby reducing the thickness of the hinge 30.

[0173] It should be noted that the thickness of the hinge 30 in the embodiment of the present application refers to the length of the hinge 30 along the height direction Z of the box body 10.

[0174] At least a portion of the cam member 370 may be disposed in the second link groove 343 to reduce the overall length of the cam member 370 and the second link 340 along the height direction Z of the box body 10 after assembly, thereby reducing the thickness of the hinge 30 .

[0175] The third link 350 may have a third link groove 353 .

[0176] For example, the third link 350 may include a fourth plate 354 , and the fourth plate 354 may extend substantially in a horizontal direction.

[0177] The third connecting rod 350 may include a fifth plate 355 , which may extend approximately in the horizontal direction. The fifth plate 355 and the fourth plate 354 may be arranged opposite to each other, and the fifth plate 355 and the fourth plate 354 may be arranged at intervals along the height direction Z of the box body 10 .

[0178] The third connecting rod 350 may include a sixth plate 356, which may extend generally vertically. The sixth plate 356 is connected between the fourth plate 354 and the fifth plate 355 to form the third connecting rod 350. This sixth plate 356 not only connects the fourth plate 354 and the fifth plate 355 but also enhances the structural strength of the third connecting rod 350. The sixth plate 356, the fourth plate 354, and the fifth plate 355 together form the third connecting rod slot 353.

[0179] refer to Figure 7 and Figure 8 , the length L1 of the cam member 370 along the height direction Z of the housing 10 can be greater than the length L2 of the third link groove 353 along the height direction Z of the housing 10. The cam member 370 can be located outside the third link groove 353, that is, the cam member 370 does not extend into the third link groove 353. Because the cam member 370 does not need to be disposed within the third link groove 353, the length of the third link groove 353 along the height direction Z of the housing 10 does not need to be increased based on the length of the cam member 370 along the height direction Z of the housing 10, thereby reducing the length of the third link groove 353 along the height direction Z of the housing 10. Compared to the implementation method of extending the cam member 370 into the third link groove 353, this embodiment of the present application reduces the length of the third link groove 353 along the height direction Z of the housing 10 while maintaining the length of the cam member 370 along the height direction Z of the housing 10, thereby reducing the thickness of the hinge 30.

[0180] Since at least part of the hinge 30 is arranged on the crossbeam of the box body 10, when the thickness of the hinge 30 is reduced, the length of the crossbeam along the height direction Z of the box body 10 can be reduced accordingly. When the height of the box body 10 is constant, the available height of the storage chamber 110 can be increased, thereby increasing the capacity of the refrigerator.

[0181] In some embodiments, reference Figure 6 , the raised rod assembly 380 may include a fixing component.

[0182] The fixing member may include a fixing seat 381, which may be block-shaped and fixed to the first connecting rod 330. The fixing seat 381 may be disposed between the first end 331 of the first connecting rod 330 and the second end 332 of the first connecting rod 330.

[0183] The fixing component may further include a first rod 382 . The first rod 382 may be disposed on a side of the fixing seat 381 facing the second end 332 of the first connecting rod 330 .

[0184] In some embodiments, reference Figure 6 , the protruding rod assembly 380 may further include a sliding component.

[0185] The sliding component may include a sliding seat 383 , which may be block-shaped and slidably disposed relative to the first connecting rod 330 .

[0186] In some possible implementations, reference Figure 4 The first connecting rod 330 can be constructed with a slide 335, and the sliding component can also include a slide rod 384. The slide rod 384 can be arranged on the side of the sliding seat 383 facing the slide 335. The slide rod 384 can be slidably arranged in the slide 335 so that the sliding seat 383 can slide relative to the first connecting rod 330 along the extension direction of the slide 335.

[0187] It can be understood that in other possible implementations, the sliding seat 383 can be constructed with a slide 335, and the side of the first connecting rod 330 facing the slide 335 can be constructed with a slide rod 384, and the slide rod 384 is slidably arranged in the slide 335 so that the sliding seat 383 can slide relative to the first connecting rod 330 along the extension direction of the slide 335.

[0188] In some embodiments, reference Figure 6 The sliding member may further include a second rod 385, the axis of which may be substantially parallel to the axis of the first rod 382. The second rod 385 is disposed on a side of the sliding seat 383 facing the first rod 382, ​​and the second rod 385 may be slidably disposed relative to the first rod 382.

[0189] In some possible implementations, reference Figure 6 The first rod 382 may be a hollow rod, and the second rod 385 may be slidably disposed in the first rod 382 so that the second rod 385 may slide relative to the first rod 382 .

[0190] In some other possible implementations, the second rod 385 may be a hollow rod, and the first rod 382 may be slidably disposed inside the second rod 385 , so that the second rod 385 may slide relative to the first rod 382 .

[0191] In some embodiments, reference Figure 6 The sliding component may further include an abutment member 386 , which is disposed on a side of the sliding seat 383 away from the second rod member 385 , and the abutment member 386 and the cam member 370 are press-fitted.

[0192] In some possible implementations, reference Figure 6 The abutting member 386 may be a roller that can be rotatably arranged relative to the sliding seat 383. When the abutting member 386 and the cam member 370 are pressed together, the contact area between the abutting member 386 and the cam member 370 is reduced, thereby reducing the friction between the abutting member 386 and the cam member 370, thereby reducing the friction noise generated when the abutting member 386 and the cam member 370 are pressed together.

[0193] In some other possible implementations, the abutment member 386 may be an abutment column, and the side wall of the abutment column and the cam member 370 are press-fitted.

[0194] In other possible implementations, the abutment member 386 may be an abutment ball, and the spherical surface of the abutment ball may be press-fitted with the cam member 370 .

[0195] In some embodiments, reference Figure 6 , the convex rod assembly 380 may further include an elastic member 387. The elastic member 387 may be a spring, a spring sheet or other elastic components. Figure 6 The elastic member 387 is shown as a spring. The elastic member 387 is disposed in a compressed state between the fixed seat 381 and the sliding seat 383. For example, the elastic member 387 can be sleeved over the first rod 382 and the second rod 385. The first rod 382 and the second rod 385 can restrict the freedom of the elastic member 387, thereby reducing radial movement of the elastic member 387 along the first rod 382 and improving the stability of the elastic member 387 during compression and release.

[0196] Under the elastic force of the elastic member 387 , the sliding seat 383 drives the abutment member 386 to slide relative to the first connecting rod 330 , so that the abutment member 386 can elastically abut against the cam member 370 during the rotation of the door body.

[0197] In some embodiments, reference Figure 6 The cam member 370 may include a self-locking segment 374 , and the self-locking segment 374 may face the abutment member 386 when the door body 20 is closed, so that the abutment member 386 can easily abut and cooperate with the self-locking segment 374 .

[0198] The self-locking section 374 can be curved. For example, the self-locking section 374 can protrude toward the abutment 386 to reduce the contact area between the self-locking section 374 and the abutment 386. When the door body 20 needs to be opened, the abutment 386 can be more easily bypassed by the self-locking section 374 under the action of external force, so as to release the self-locking force of the hinge 30 on the door body 20.

[0199] In some embodiments, reference Figure 6 The cam member 370 may further include a curved segment 373. The curved segment 373 and the self-locking segment 374 may have a smooth transition.

[0200] refer to Figure 9 and Figure 10 The abutment member 386 presses against the curved section 373 within at least a portion of the angle range before the door body 20 is closed. Figure 6 The abutment member 386 presses against the self-locking section 374 when the door body 20 is closed. As the abutment member 386 moves from engaging with the curved section 373 to engaging with the self-locking section 374, the curved section 373 allows for a smooth transition of the elastic force of the protruding rod assembly 380 on the self-locking section 374, reducing the impact force on the door body 20 when the elastic force of the protruding rod assembly 380 is quickly released. This reduces the vibration amplitude and noise during the closing process of the door body 20.

[0201] In some embodiments, the curved segment 373 may be arc-shaped, and the center of the circle corresponding to the curved segment 373 may be located at the axis of the first pivot axis 371. Thus, when the abutting member 386 elastically presses against the curved segment 373, the abutting member 386 and the curved segment 373 are substantially tangential, and the direction of the elastic force F2 (or F3) exerted by the abutting member 386 on the curved segment 373 substantially passes through the axis of the first pivot axis 371. Therefore, the moment arm from the axis of the first pivot axis 371 to the elastic force F2 (or F3) is relatively small, and the elastic force F2 (or F3) is unlikely to cause the second connecting rod 340 to rotate about the axis of the first pivot axis 371. Consequently, the elastic force is unlikely to affect the opening and closing of the hinge 30.

[0202] It is understandable that the curved segment 373 may also have a certain deviation relative to the arc shape, as long as the direction of the elastic force of the abutment member 386 on the curved segment 373 roughly passes through the axis of the first pivot shaft 371 .

[0203] In some embodiments, reference Figure 11 The thickness L3 of the first end 331 of the first connecting rod 330 can be smaller than the thickness L4 of the second end 332 of the first connecting rod 330. The first end 331 of the first connecting rod 330 can be nested in the mounting base 310 to reduce the length of the whole formed by the first connecting rod 330 and the mounting base 310 after assembly along the height direction Z of the box body 10, thereby reducing the thickness of the hinge 30.

[0204] In some embodiments, reference Figure 11 The first connecting rod 330 has a top surface 333 and a bottom surface 334 at both ends along the height direction Z of the box body 10. The top of the first end 331 of the first connecting rod 330 can be lower than the top surface 333 of the first connecting rod 330, that is, the top of the first end 331 of the first connecting rod 330 is sunken relative to the top surface 333 of the first connecting rod. Exemplarily, the top of the first end 331 of the first connecting rod 330 can be sunken by 1.9 mm relative to the top surface 333 of the first connecting rod 330.

[0205] The bottom of the first end 331 of the first connecting rod 330 may be higher than the bottom surface 334 of the first connecting rod 330, that is, the bottom of the first end 331 of the first connecting rod 330 is recessed upward relative to the bottom surface 334 of the first connecting rod 330. For example, the bottom of the first end 331 of the first connecting rod 330 may be recessed upward relative to the bottom surface 334 of the first connecting rod 330 by 1.9 mm, so that the length of the first end 331 of the first connecting rod 330 along the height direction Z of the box body 10 can be reduced by 3.8 mm.

[0206] This arrangement reduces the length L3 of the first end 331 of the first connecting rod 330 along the height direction Z of the box body 10, thereby reducing the length of the mounting base 310 adapted to the first end 331 of the first connecting rod 330 along the height direction Z of the box body 10. Since the mounting base 310 is located at the outermost portion of the hinge 30, the reduced length of the mounting base 310 along the height direction Z of the box body 10 can reduce the length of the entire hinge 30 along the height direction Z of the box body 10, thereby reducing the thickness of the hinge 30.

[0207] In some embodiments, the mounting base 310 may have a reinforced flange that can be folded away from the front wall 120 of the box 10. The reinforced flange can be formed by folding the top and bottom ends of the mounting base 310 away from the front wall 120 of the box 10. The reinforced flange can increase the structural strength of the mounting base 310 and prevent the mounting base 310 from deformation.

[0208] The mounting base 310 may be a sheet metal part, which has high structural strength and is easy to construct a reinforcing flange.

[0209] In some embodiments, reference Figure 5 and Figure 11 The reinforcing flange may include a first reinforcing flange 311 and a second reinforcing flange 312 , and the first reinforcing flange 311 and the second reinforcing flange 312 may be spaced apart along the height direction Z of the box body 10 .

[0210] refer to Figure 5When the hinge 30 is closed, the end of the reinforcing flange away from the front wall 120 of the box body 10 and the end of the first connecting rod 330 away from the swing arm 320 can be spaced apart, that is, the end of the first connecting rod 330 away from the swing arm 320 is not arranged between the first reinforcing flange 311 and the second reinforcing flange 312, and the end of the first connecting rod 330 away from the swing arm 320 is not nested in the mounting seat 310.

[0211] Because the first connecting rod 330 does not need to be accommodated between the first reinforcing flange 311 and the second reinforcing flange 312, the length of the spacing between the first reinforcing flange 311 and the second reinforcing flange 312 along the height direction Z of the housing 10 does not need to be increased based on the length of the first connecting rod 330 along the height direction Z of the housing 10. The spacing L5 between the first reinforcing flange 311 and the second reinforcing flange 312 can be less than or equal to the thickness L4 of the end of the first connecting rod 330 facing away from the swing arm 320. Compared to an implementation in which the end of the first connecting rod 330 facing away from the swing arm 320 is nested within the mounting base 310, this embodiment of the present application reduces the length of the mounting base 310 along the height direction Z of the housing 10 while maintaining a constant length of the first connecting rod 330 along the height direction Z of the housing 10. Because the mounting base 310 is located at the outermost portion of the hinge 30, the reduced length of the mounting base 310 along the height direction Z of the housing 10 can reduce the length of the entire hinge 30 along the height direction Z of the housing 10, thereby reducing the thickness of the hinge 30.

[0212] In some embodiments, when the hinge 30 is closed, a gap L6 between an end of the reinforcing flange facing away from the front wall 120 and an end of the first link 330 close to the front wall 120 along the depth direction Y of the refrigerator is greater than 0 and less than or equal to 2 mm.

[0213] When L6 is greater than 2 mm, the distance between the end of the reinforcing flange facing away from the front wall 120 and the end of the first connecting rod 330 close to the front wall 120 along the depth direction Y of the box body 10 will be too large, resulting in the hinge 30 being too long along the depth direction Y of the box body 10 when closed, resulting in the depth of the refrigerator being too large.

[0214] When the interval L6 between the end of the reinforced flange facing away from the front wall 120 and the end of the first connecting rod 330 close to the front wall 120 along the depth direction Y of the refrigerator is greater than 0 and less than or equal to 2 mm, it can not only ensure the structural strength of the mounting base 310, but also reduce the interference between the first connecting rod 330 and the mounting base 310 during the opening and closing process of the hinge 30, thereby reducing the possibility of interference between the first connecting rod 330 and the mounting base 310 due to assembly errors.

[0215] For example, the length of the reinforcing flange along the depth direction Y of the box body can be 3.5 mm, and the length of the end of the reinforcing flange close to the front wall 120 and the end of the first connecting rod 330 close to the front wall 120 along the depth direction of the refrigerator can be 5 mm. In this way, the distance L6 between the end of the reinforcing flange facing away from the front wall 120 and the end of the first connecting rod 330 close to the front wall 120 along the depth direction Y of the refrigerator is 1.5 mm.

[0216] When the length of the reinforcing flange along the depth direction Y of the refrigerator body can be 3.5 mm, the structural strength of the mounting base 310 is enhanced. When the spacing L6 between the end of the reinforcing flange facing away from the front wall 120 and the end of the first connecting rod 330 closer to the front wall 120 along the depth direction Y of the refrigerator is 1.5 mm, interference between the first connecting rod 330 and the mounting base 310 is reduced during the opening and closing of the hinge 30, thereby reducing the possibility of interference between the first connecting rod 330 and the mounting base 310 due to assembly errors.
