[0073] The following is combined with Figures 1-13, the door assembly and refrigeration equipment provided by the utility model embodiment are described in detail through specific embodiments and their application scenarios.

[0074] In the first aspect, Figure 1 、 Figure 2 and Figure 7 As shown, the present invention provides a door assembly for use in refrigeration equipment, comprising: a box door 1, a cabinet door 2, a sliding module 4, a sliding door mechanism 6 and a hanging structure 5;

[0075] The door 1 is rotatably mounted on the housing 3 of the refrigeration equipment, and the cabinet door 2 is located on a side of the door 1 facing away from the housing 3;

[0076] The sliding module 4 includes a slide rail 41, a first slide member 42, and a second slide member 43. The slide rail 41 is provided on the door 1 and extends along the width direction of the door 1. The first slide member 42 and the second slide member 43 are movably provided on the slide rail 41, and the first slide member 42 and the second slide member 43 are transmission-connected to move in opposite directions relative to the slide rail 41.

[0077] The sliding door mechanism 6 is configured to be provided on the box body 3 and connected to the second sliding member 43. The sliding door mechanism 6 is used to drive the second sliding member 43 to move along the slide rail 41 during the process of opening and closing the box door 1.

[0078] The hanging structure 5 includes a supporting member 51, a hanging member 52, and a locking member 53. The supporting member 51 is provided on the first sliding member 42. The hanging member 52 is provided on the cabinet door 2 and is movably hung on the supporting member 51 along the height direction of the cabinet door 2. The locking member 53 is locked between the supporting member 51 and the hanging member 52 to limit the installation position of the hanging member 52 relative to the supporting member 51 along the height direction.

[0079] Among them, the cabinet door 2 includes any one of a wooden door panel and a plastic door panel, the thickness of the cabinet door 1 is 18-60mm, for example, the thickness of the cabinet door 1 can be 18mm, 25mm, 35mm, 50mm, 55mm or 60mm; the thickness of the cabinet door 2 is 12-26mm, for example, the thickness of the cabinet door 2 can be 12mm, 15mm, 20mm or 26mm.

[0080] It is understood that the door assembly is used in refrigeration equipment such as refrigerators and freezers. The cabinet 3 of the refrigeration equipment is provided with a hinge 9. The cabinet door 1 is rotatably connected to the cabinet 3 via the hinge 9 to enable the cabinet door 1 to be opened or closed relative to the cabinet 3. The cabinet door 2 is provided on the outside of the cabinet door 1. The cabinet door 2 and the surrounding cabinet can be made of the same material to ensure that the appearance of the refrigeration equipment is consistent with the surrounding cabinets, making the refrigeration equipment more coordinated with the surrounding environment.

[0081] For the sliding module 4, the slide rail 41 can be a parallel rail well-known in the art, that is, the slide rail 41 includes a first rail and a second rail arranged side by side. The first slider 42 is movably arranged on the first rail, and the second slider 43 is movably arranged on the second rail.

[0082] The first slider 42 and the second slider 43 have the same structure, both including a connected ball bracket and an adapter seat; the ball bracket of the first slider 42 is slidably arranged on the first rail, and the adapter seat of the first slider 42 is connected to the supporting member 51 of the hanging structure 5; the ball bracket of the second slider 43 is slidably arranged on the second rail, and the adapter seat of the second slider 43 is connected to the sliding door mechanism 6.

[0083] The sliding door mechanism 6 can be a link mechanism or a telescopic mechanism arranged between the box body 3 and the box door 1, and no specific limitation is made here, as long as it can drive the second slider 43 to move along the slide rail 41 during the opening and closing process of the box door 1.

[0084] A linkage structure can be arranged on the slide rail 41 to realize the transmission connection between the first slider 42 and the second slider 43. This design can make the second slider 43 drive the first slider 42 to move in the second direction along the extension direction of the slide rail 41 when the second slider 43 moves in the first direction along the extension direction of the slide rail 41, and the second direction is opposite to the first direction; conversely, when the second slider 43 moves in the second direction, it will drive the first slider 42 to move in the first direction.

[0085] In practical applications, since the first slider 42 and the second slider 43 move in opposite directions relative to the slide rail 41, when the sliding door mechanism 6 drives the second slider 43 to move along the width direction of the box door 1 towards the side close to the hinge 9, the first slider 42 will drive the cabinet door 2 to move along the width direction of the box door 1 towards the side away from the hinge 9 through the hanging structure 5; conversely, when the sliding door mechanism 6 drives the second slider 43 to move along the width direction of the box door 1 towards the side away from the hinge 9, the first slider 42 will drive the cabinet door 2 to move along the width direction of the box door 1 towards the side close to the hinge 9 through the hanging structure 5.

[0086] For the hanging structure 5, the hanging member 52 is detachably installed on the cabinet door 2 through fasteners such as bolts and rivets. The supporting member 51 can be detachably installed on the first slider 42 through fasteners or can be set as an integral structure with the first slider 42; the supporting member 51 can be provided with hanging structures such as hanging grooves and bayonets so that the hanging member 52 can be quickly and reliably hung on the hanging structure under the action of the gravity of the cabinet door 2 and can move relative to the supporting member 51 in the height direction.

[0087] Further, the locking member 53 can be a bolt, a locking pin, a magnetic attracting member, etc. well-known in the art. After the installation position of the hanging member 52 relative to the supporting member 51 is adjusted, the hanging member 52 and the supporting member 51 can be connected into one body by the locking member 53 to prevent the hanging member 52 from moving relative to the supporting member 51.

[0088] As can be seen from the above, by providing the sliding module 4 and the hanging structure 5 between the cabinet door 1 and the cabinet door 2, and configuring the sliding door mechanism 6 for pulling the second sliding member 43 of the sliding module 4, when installing the cabinet door 2, the slide rail 41 of the sliding module 4 can be connected to the cabinet door 1 to realize the installation of the sliding module 4. Then, the supporting member 51 is installed on the first sliding member 42 of the sliding module 4, the hanging member 52 is installed on the cabinet door 2, and the hanging member 52 is hung on the supporting member 51, and the installation of the cabinet door 2 can be quickly realized; then, the installation position of the hanging member 52 relative to the supporting member 51 is adjusted in the height direction, and the relative position of the hanging member 52 and the supporting member 51 is locked by the locking member 53, and the adjustment of the installation position of the cabinet door 2 relative to the cabinet door 1 in the height direction is conveniently realized; this cabinet door installation method is not only convenient to operate, reduces the labor intensity of the installation personnel, but also ensures the aesthetics of the cabinet door installation.

[0089] Further, in practical applications, when the refrigeration equipment is installed in the cabinet in an embedded manner, during the process of opening or closing the cabinet door 1, the sliding door mechanism 6 can pull the second sliding member 43 to move relative to the slide rail 41, so that the first sliding member 42 moves along the slide rail 41 in the opposite direction, and then the first sliding member 42 drives the cabinet door 2 to move left and right relative to the cabinet door 1 in the width direction through the hanging structure 5, avoiding the cabinet door 2 from touching the surrounding cabinets during the opening and closing process of the cabinet door 1, and meeting the normal opening and closing requirements of the cabinet door 1 of the refrigeration equipment.

[0090] In some embodiments, as Figure 3 and Figure 4 shown, the supporting member 51 is provided with a hanging hole 5101, and the hanging member 52 is movably inserted through the hanging hole 5101 in the height direction and is hung on the supporting member 51 based on the hanging hole 5101.

[0091] It can be understood that the opening shape of the hanging hole 5101 can be circular, rectangular, waist-shaped, oval, etc., and a part of the hanging member 52 inserted through the hanging hole 5101 can move relative to the supporting member 51 in the height direction, thereby changing the hanging position of the hanging member 52 relative to the supporting member 51 in the height direction.

[0092] Meanwhile, when the hanging member 52 is inserted into the hanging hole 5101, at least a part of the hanging member 52 is supported on the upper side of the supporting member 51, so as to ensure that the hanging member 52 is hung on the supporting member 51 based on the hanging hole 5101 and can be used to support the cabinet door 2 connected thereto. Of course, after the hanging position of the hanging member 52 relative to the supporting member 51 is adjusted in the height direction, the supporting member 51 and the hanging member 52 are locked and connected by the locking member 53, and the locking member 53 relies on the supporting member 51 to support the hanging member 52.

[0093] In practical applications, in order to facilitate locking the hanging member 52 to the supporting member 51 by the locking member 53, the locking member 53 can be configured to be horizontally arranged and extend along the width direction of the cabinet door 1 or the cabinet door 2.

[0094] In some embodiments, as Figure 4 and Figure 5 shown, a part of the hanging member 52 inserted into the hanging hole 5101 is structurally adapted to the hanging hole 5101, and the hanging member 52 is slidably engaged with the supporting member 51 along the height direction under the guidance of the hanging hole 5101.

[0095] It can be understood that by guiding the hanging member 52 to slide relative to the supporting member 51 along the height direction by using the hanging hole 5101, while preventing the hanging member 52 from detaching from the supporting member 51, it can also prevent the hanging member 52 from shaking relative to the supporting member 51 along the width direction of the cabinet door 1 or the cabinet door 2, thereby ensuring the stability of the hanging of the hanging member 52 on the supporting member 51.

[0096] Furthermore, the hanging hole 5101 can be a strip-shaped hole and is configured to extend along the width direction of the cabinet door 1 or the cabinet door 2; here, the width of the hanging hole 5101 extending along the width direction can be adapted to the width of a part of the hanging member 52 inserted into the hanging hole 5101 along the width direction to ensure the stability of the movement of the hanging member 52 relative to the supporting member 51.

[0097] In some embodiments, as Figure 5 and Figure 6 shown, the hanging member 52 includes: a hook 521 and a fixing seat 522; the hook 521 is inserted into the hanging hole 5101 and is hung on the supporting member 51; the fixing seat 522 is connected to the hook 521 and is configured to be detachably connected to the cabinet door 2.

[0098] It can be understood that the hook 521 and the fixing seat 522 can be an integral structure. For example, the hook 521 and the fixing seat 522 form an integral metal hanging part or an integral plastic hanging part.

[0099] The hook 521 is in a hooked shape and is vertically downwardly hung on the supporting member 51. One end of the hook 521 is inserted into the hanging hole 5101, and the other end of the hook 521 is connected to the fixing base 522.

[0100] Meanwhile, the fixing base 522 can be detachably mounted on the cabinet door 2 through fasteners such as bolts and rivets.

[0101] Optionally, the fixing base 522 is provided with mounting holes, and the fixing base 522 is mounted on the cabinet door 2 through fasteners passing through the mounting holes.

[0102] Optionally, as Figure 1 and Figure 5 shown, the mounting holes include a circular hole and an oval hole. The oval hole extends along the height direction of the cabinet door 2. The diameter of the circular hole is adapted to the diameter of the fastener. The width of the oval hole extending along the width direction is adapted to the diameter of the fastener. The length of the oval hole extending along the height direction is greater than the diameter of the fastener. Thus, based on the oval hole, the mounting position of the hanging member 52 relative to the cabinet door 2 can be adjusted along the height direction, and further the mounting height of the cabinet door 2 relative to the box door 1 can be adjusted.

[0103] Further, two circular holes can be provided. The two circular holes are arranged on both sides of the oval hole along the width direction.

[0104] In some embodiments, as Figure 5 shown, in order to reliably hang the hanging member 52 on the supporting member 51, the hook 521 includes: a hook head 5211, a first connecting portion 5212, and a second connecting portion 5213; the hook head 5211 is movably inserted into the hanging hole 5101 along the height direction, the first connecting portion 5212 is connected between the hook head 5211 and the fixing base 522; the second connecting portion 5213 is connected to the first connecting portion 5212, and the locking member 53 is locked between the supporting member 51 and the second connecting portion 5213.

[0105] Specifically, the hook head 5211 can be configured to extend along the height direction of the cabinet door 2, the first connecting portion 5212 can be configured as an "L" - shaped structure. One end of the first connecting portion 5212 is connected to the hook head 5211, and the other end of the first connecting portion 5212 is connected to the fixing base 522. Among them, the first connecting portion 5212 and the hook head 5211 are configured as a hooked structure, and at least part of the first connecting portion 5212 can be configured to be supported on the supporting member 51.

[0106] Meanwhile, the second connecting portion 5213 can be arranged on the upper side of the first connecting portion 5212 along the height direction. This design can reserve sufficient space for connecting the supporting member 51 and the second connecting portion 5213 of the hanging member 52 into one body by using the locking member 53 while not affecting the hanging of the hanging member 52 on the supporting member 51.

[0107] In some embodiments, as Figure 4 shown, the supporting member 51 includes: a bottom plate 511 and at least one side plate 512; the bottom plate 511 is connected to the first sliding member 42, and a hanging hole 5101 is provided on the bottom plate 511; at least one side plate 512 is respectively connected to the bottom plate 511 and the first sliding member 42.

[0108] It can be understood that in the case where the hook 521 includes: a hook head 5211, a first connecting portion 5212 and a second connecting portion 5213, the hook head 5211 passes through the hanging hole 5101 on the bottom plate 511, and the locking member 53 can be configured to be locked between the side plate 512 and the second connecting portion 5213.

[0109] Meanwhile, since the bottom plate 511 is connected to the first sliding member 42 through the side plate 512, the side plate 512 functions as a reinforcing rib, which can enhance the bonding strength between the bottom plate 511 and the first sliding member 42, and ensure that the hanging member 52 is better supported based on the bottom plate 511 and the side plate 512.

[0110] Wherein, the bottom plate 511 can be set to extend along the width direction, and two side plates 512 can be provided. The two side plates 512 are arranged at both ends of the bottom plate 511 along the width direction.

[0111] In some embodiments, as Figure 3 shown, the locking member 53 includes a locking bolt, and the supporting member 51 is provided with an adjusting hole 5102; the nut of the locking bolt is limited to one side of the supporting member 51, and the screw rod of the locking bolt is movably passed through the adjusting hole 5102 along the height direction and is threadedly connected to the hanging member 52.

[0112] It can be understood that the adjusting hole 5102 can be provided on the side plate 512 of the supporting member 51; the adjusting hole 5102 can be an oval hole and is configured to extend along the height direction of the cabinet door 1; a threaded hole 5201 can be provided on the hanging member 52, for example, the threaded hole 5201 is provided on the second connecting portion 5213 of the hanging member 52.

[0113] In practical applications, in the direction from left to right, the screw rod of the locking bolt can be horizontally passed through the adjusting hole 5102 and then preliminarily connected to the threaded hole 5201 on the hanging member 52; after the installation position of the hanging member 52 relative to the supporting member 51 is adjusted along the height direction, the locking bolt is then screwed until the locking bolt locks the hanging member 52 and the supporting member 51 together to prevent the hanging member 52 from moving relative to the supporting member 51.

[0114] In some embodiments, as Figure 8As shown in the figure, the sliding door mechanism 6 includes: a driving component 61 and a transmission component 62; the first end of the driving component 61 is configured to be rotatably arranged on the box body 3, and the second end of the driving component 61 is configured to be rotatably arranged on the box door 1. The first end of the driving component 61 is arranged offset from the hinge axis between the box body 3 and the box door 1; the transmission component 62 is configured to be arranged between the second end of the driving component 61 and the second sliding member 43;

[0115] During the process of the box door 1 opening or closing the box body 3, the second end of the driving component 61 rotates relative to the box door 1, thereby driving the transmission component 62 to drive the second sliding member 43 to move along the width direction of the box door 1.

[0116] It can be understood that since the box door 1 is rotatably connected to the box body 3 through the hinge axis on the hinge 9, a fixed axis can be set at a position on the hinge 9 that deviates from the hinge axis, and the first end of the driving component 61 can be rotatably arranged on the hinge 9 through the fixed axis.

[0117] When the box door 1 rotates relative to the box body 3 around the hinge axis, the second end of the driving component 61 rotates in a circular motion with the hinge axis as the center. Since the first end of the driving component 61 is arranged offset from the hinge axis, the distance between the first end and the second end of the driving component 61 will change. And the position of the second end of the driving component 61 on the box door 1 is fixedly set, so the box door 1 will drive the second end of the driving component 61 to rotate relative to the box door 1 during the opening and closing process.

[0118] Optionally, the driving component 61 can be a crank mechanism or a connecting rod mechanism.

[0119] The transmission component 62 is used to convert the rotational motion of the driving component 61 into a linear motion, and drive the second sliding member 43 to move left and right relative to the box door 1 along the width direction. Since the first sliding member 42 and the second sliding member 43 move in opposite directions along the slide rail 41, the first sliding member 42 will drive the cabinet door 2 to move in the direction opposite to the second sliding member 43 through the hanging structure 5.

[0120] Optionally, the transmission component 62 can be a crank-slider mechanism or a gear-rack transmission mechanism.

[0121] In practical applications, during the opening process of the cabinet door 1, the cabinet door 1 drives the second end of the driving component 61 to rotate relative to the hinge axis. Based on the misaligned arrangement of the first end of the driving component 61 and the hinge axis, the distance between the first end and the second end of the driving component 61 increases, thereby forcing the second end of the driving component 61 to rotate clockwise relative to the cabinet door 1. Furthermore, it controls the transmission component 62 to drive the cabinet door 2 to move away from the hinge 9 along the width direction of the cabinet door 1, that is, to move leftward relative to the cabinet door 1. In this way, interference between the cabinet door 2 and the side cabinets can be avoided; during the closing process of the cabinet door 1, the cabinet door 1 drives the second end of the driving component 61 to rotate relative to the hinge axis. Based on the misaligned arrangement of the first end of the driving component 61 and the hinge axis, the distance between the first end and the second end of the driving component 61 decreases, driving the second end of the driving component 61 to rotate counterclockwise relative to the cabinet door 1. Furthermore, it controls the transmission component 62 to drive the cabinet door 2 to move towards the hinge 9 along the width direction of the cabinet door 1, that is, to move rightward relative to the cabinet door 1. In this way, it can ensure that the cabinet door 2 can avoid the side cabinets when the cabinet door 1 is closed and reset the cabinet door 2.

[0122] In some embodiments, as Figure 8 shown, the driving component 61 includes: a first connecting rod 611 and a second connecting rod 612; the first end of the first connecting rod 611 is rotatably arranged on the box body 3 and is misaligned with the hinge axis; the first end of the second connecting rod 612 is rotatably connected to the second end of the first connecting rod 611; the second end of the second connecting rod 612 is rotatably arranged on the cabinet door 1 and is connected to the transmission component 62.

[0123] It can be understood that the first connecting rod 611 and the second connecting rod 612 are connected by a hinge axis, the first connecting rod 611 and the second connecting rod 612 can rotate relative to each other, the first connecting rod 611 can rotate relative to the box body 3, and the second connecting rod 612 can rotate relative to the cabinet door 1.

[0124] Since the first end of the first connecting rod 611 is misaligned with the hinge axis, during the opening or closing process of the cabinet door 1, the distance between the second end of the second connecting rod 612 and the first end of the first connecting rod 611 changes, while the position of the second end of the second connecting rod 612 relative to the cabinet door 1 remains unchanged, resulting in the second end of the second connecting rod 612 rotating around the cabinet door 1 and driving the transmission component 62 to drive the cabinet door 2 to move along the width direction of the cabinet door 1.

[0125] In practical applications, during the opening process of the cabinet door 1, the cabinet door 1 drives the second end of the second link 612 to rotate relative to the hinge axis. Based on the misaligned arrangement of the first end of the first link 611 and the hinge axis, the distance between the first end of the first link 611 and the second end of the second link 612 increases, driving the second end of the second link 612 to rotate clockwise relative to the cabinet door 1. Furthermore, it controls the transmission assembly 62 to drive the second sliding member 43 to move towards the direction close to the hinge 9, and then the first sliding member 42 drives the cabinet door 2 to move away from the hinge 9 through the hanging structure 5, that is, move to the left relative to the cabinet door 1, so as to avoid interference between the cabinet door 2 and the side cabinets.

[0126] During the closing process of the cabinet door 1, the cabinet door 1 drives the second end of the second link 612 to rotate relative to the hinge axis. Based on the misaligned arrangement of the first end of the first link 611 and the hinge axis, the distance between the first end of the first link 611 and the second end of the second link 612 decreases, driving the second end of the second link 612 to rotate counterclockwise relative to the cabinet door 1. Furthermore, it controls the transmission assembly 62 to drive the second sliding member 43 to move away from the hinge 9, and then the first sliding member 42 drives the cabinet door 2 to move towards the direction close to the hinge 9 through the hanging structure 5, that is, move to the right relative to the cabinet door 1, so as to ensure that the cabinet door 2 can avoid the cabinet door 2 of the side cabinet body when the cabinet door 1 is closed and reset the cabinet door 2.

[0127] In some embodiments, as Figure 8 shown, the transmission assembly 62 includes: a gear set 621 and a rack 622; the gear set 621 includes a first gear and a second gear, the first gear and the second gear are meshed and arranged, and are respectively rotatably arranged on the cabinet door 1; the first gear is coaxially connected to the second end of the driving assembly 61 and can rotate under the drive of the driving assembly 61; the rack 622 is meshed with the second gear, the rack 622 extends in the width direction and is configured to be connected to the second sliding member 43.

[0128] It can be understood that when the cabinet door 1 is opened, the cabinet door 1 drives the second end of the driving assembly 61 to rotate relative to the hinge axis, the distance between the first end and the second end of the driving assembly 61 increases, driving the second end of the driving assembly 61 to rotate clockwise relative to the cabinet door 1. Since the installation position of the gear set 621 on the cabinet door 1 remains unchanged, the second end of the driving assembly 61 drives the first gear to rotate clockwise, and the second gear rotates counterclockwise to drive the rack 622 to drive the second sliding member 43 to move along the width direction of the cabinet door 1 towards the direction close to the hinge 9, and then the first sliding member 42 drives the cabinet door 1 to move away from the hinge 9, so as to avoid interference between the cabinet door 2 and the side cabinets.

[0129] During the process of closing the door 1, the door 1 drives the second end of the driving component 61 to rotate relative to the hinge shaft, and the distance between the first end and the second end of the driving component 61 is reduced, driving the second end of the driving component 61 to rotate counterclockwise relative to the door 1. Since the installation position of the gear set 621 on the door 1 remains unchanged, the second end of the driving component 61 drives the first gear to rotate counterclockwise, and the second gear rotates clockwise to drive the rack 622 to drive the second sliding member 43 to move along the width direction of the door 1 away from the hinge 9, and then the first sliding member 42 drives the door 1 to move toward the hinge 9. This ensures that when the door 1 is closed, the door 2 can avoid the cabinet on the side and reset the door 2.

[0130] In some embodiments, in order to ensure the stability and reliability of the movement of the cabinet door 2 relative to the box door 1, the sliding modules 4 and the hanging structures 5 are respectively provided with multiple sets, and are arranged one by one relative to each other. The sliding modules 4 are provided with multiple sets, and the multiple sets of sliding modules 4 are arranged between the box door 1 and the cabinet door 2. The sliding door mechanism 6 is connected to the second sliding part 43 of one of the multiple sets of sliding modules 4.

[0131] Specifically, there are four sets of sliding modules 4, two sets of sliding modules 4 are arranged along the width direction of the box door 1 and are arranged between the upper end of the box door 1 and the upper end of the cabinet door 2, and the other two sets of sliding modules 4 are arranged along the width direction of the box door 1 and are arranged between the lower end of the box door 1 and the lower end of the cabinet door 2.

[0132] In some embodiments, as Figure 10 As shown, the box door 1 is provided with a groove 101 , and the sliding module 4 is provided in the groove 101 ; the door body assembly further comprises a decorative piece, and the decorative piece cover is used to cover the notch end of the groove 101 .

[0133] It is understood that when the cabinet door 2 is installed on the outside of the box door 1, the sliding module 4 on the box door 1 is connected to the cabinet door 2 via the hanging structure 5. At this time, there is no decorative piece at the notch end of the groove 101. Among them, the slide rail 41 of the sliding module 4 is connected to the bottom of the groove 101.

[0134] In some application scenarios, if the cabinet door 2 is no longer installed on the outside of the box door 1, the sliding module 4 is no longer used. By setting a decorative cover at the notch end of the groove 101, the sliding module 4 can be hidden to ensure the aesthetic appearance of the box door 1.

[0135] In some embodiments, as Figure 7 As shown, the sliding module 4 also includes: a coupling component 44, which is arranged on the slide rail 41 and is transmission-connected between the first sliding member 42 and the second sliding member 43; wherein the coupling component 44 is used to control the first sliding member 42 and the second sliding member 43 to move in opposite directions relative to the slide rail 41.

[0136] It is understandable that the coupling component 44 includes a first pull rope and a second pull rope. The first pull rope is wound around the first end of the slide rail 41, and the second pull rope is wound around the second end of the slide rail 41. The first pull rope, the first sliding member 42, the second pull rope, and the second sliding member 43 are sequentially connected end to end to form an annular structure. In this way, when the sliding door mechanism 6 pulls the first sliding member 42 to move along the slide rail 41, the moving directions of the first sliding member 42 and the second sliding member 43 relative to the slide rail 41 are opposite.

[0137] In some examples, as Figure 9 shown, the coupling component 44 includes a first rack 441, a coupling gear 442, and a second rack 443; the coupling gear 442 is rotatably arranged on the slide rail 41 and is respectively meshed with the first rack 441 and the second rack 443; the first rack 441 is connected to the first sliding member 42, and the second rack 443 is connected to the second sliding member 43.

[0138] It is understandable that the coupling gear 442 is rotatably arranged at a set position on the slide rail 41. The first rack 441 and the second rack 443 are spaced apart from each other and are respectively arranged on both sides of the coupling gear 442. The tooth surfaces of the first rack 441 and the second rack 443 are arranged oppositely.

[0139] When the second sliding member 43 drives the second rack 443 to move along the slide rail 41 towards the side close to the hinge 9, the second rack 443 will drive the coupling gear 442 to rotate. Then, based on the meshing arrangement of the coupling gear 442 and the first rack 441, the first rack 441 drives the first sliding member 42 to move towards the side away from the hinge 9, so as to realize the reverse movement of the first sliding member 42 and the second sliding member 43 relative to the slide rail 41.

[0140] In a second aspect, as Figure 10 , Figure 11 , Figure 12 and Figure 13 shown, an embodiment of the present invention further provides a refrigeration device, including: a box body 3 and the door body assembly as described in any one of the above. The box body 3 has a storage compartment, and the box door 1 is rotatably arranged on the box body 3 to open or close the storage compartment.

[0141] It is understandable that the box body 3 can be provided with multiple storage compartments, and the multiple storage compartments are sequentially arranged from top to bottom along the height direction of the box body 3. The box body 3 is configured with a set of door body assemblies for controlling the opening and closing states for each storage compartment. Among them, the box body 3 is provided with a hinge 9 on one side corresponding to each storage compartment, and the box body 3 can be rotatably connected to the box door 1 of the door body assembly corresponding to the storage compartment through the hinge 9.

[0142] For each set of door body components, since the cabinet door 2 can move left and right relative to the box door 1 in the width direction, when the refrigeration device is fully embedded, during the process of opening the box door 1, the cabinet door 2 can be controlled to move away from the hinge 9 relative to the box door 1 to avoid the cabinet body around the refrigeration device; during the process of closing the box door 1, the cabinet door 2 can be controlled to move closer to the hinge 9 relative to the box door 1 until the cabinet door 2 returns to its original position, ensuring that the side edges of the box door 1 and the cabinet door 2 are flush.

[0143] Since the refrigeration device includes a door body component, and the specific structure of the door body component refers to the above-mentioned embodiment, the refrigeration device shown in this embodiment includes all the technical solutions of the above-mentioned embodiment. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above-mentioned embodiment, which will not be elaborated here one by one.

[0144] In some embodiments, as Figure 11 shown, the refrigeration device is configured to be disposed in the accommodation space between the first cabinet body 7 and the second cabinet body 8; during the process of opening or closing the box door 1, the sliding door mechanism 6 is used to change the position of the cabinet door 2 on the box door 1 so that the cabinet door 2 can avoid the first cabinet body 7 or the second cabinet body 8.

[0145] It can be understood that there is an opening on the outer side of the accommodation space between the first cabinet body 7 and the second cabinet body 8, and this design enables the box body 3 of the refrigeration device to be integrally embedded in the accommodation space. During the process of the box door 1 passing through the opening to control the opening or closing of the accommodation space, the sliding door mechanism 6 is configured to drive the cabinet door 2 to move away from or closer to the hinge 9 in the width direction. This design can ensure that the cabinet door 2 avoids the side walls of the first cabinet body 7 and the second cabinet body 8, preventing the cabinet door 2 from interfering with the side walls of the first cabinet body 7 and the second cabinet body 8 and meeting the requirement that the box door 1 can be smoothly opened and closed.

[0146] During the process of opening the box door 1, the sliding door mechanism 6 drives the cabinet door 2 to move a preset distance away from the hinge 9 in the width direction. In this way, the cabinet door 2 can smoothly avoid the side wall of the second cabinet body 8, enabling the box door 1 to be fully opened, which is convenient for users to access items.

[0147] Similarly, during the process of closing the box door 1, the sliding door mechanism 6 drives the cabinet door 2 to move a preset distance closer to the hinge 9 in the width direction. When the box door 1 is fully closed, the cabinet door 2 will return to its initial position. In this way, the cabinet door 2 can smoothly avoid the side wall of the first cabinet body 7, enabling the box door 1 to be fully closed, maintaining the overall aesthetics and sealing performance.

[0148] In this embodiment, the cabinet door 2 is movably arranged outside the door 1 of the refrigerator along the width direction of the door 1 of the refrigerator, and the sliding door mechanism 6 is used to drive the cabinet door 2 to move relative to the door 1 of the refrigerator during the opening or closing process of the door 1 of the refrigerator, so that the door 1 of the refrigerator can avoid the first cabinet body 7 and the second cabinet body 8 on the side during the opening and closing processes, avoiding the interference between the cabinet door 2 and the outside when the door 1 of the refrigerator rotates, and meeting the usage requirements of users in different scenarios. This design not only improves the convenience of use, but also can avoid the possible damage of the door assembly during use. At the same time, this design also enables the refrigeration equipment to better integrate into the home environment, achieving the effects of overall beauty and sealing.

[0149] In some embodiments, as Figure 12 and Figure 13 shown, the door 1 of the refrigerator is rotatably connected to the box body 3 through a hinge 9, and the cabinet door 2 can move relative to the door 1 of the refrigerator between a first position and a second position along the width direction; when the cabinet door 2 is in the first position, the door 1 of the refrigerator closes the storage compartment, and the side of the cabinet door 2 facing the hinge 9 approaches the hinge 9; when the cabinet door 2 is in the second position, the door 1 of the refrigerator opens the storage compartment, and the side of the cabinet door 2 facing the hinge 9 is away from the hinge 9. At this time, the side of the cabinet door 2 and the side of the door 1 of the refrigerator are misaligned to avoid the side wall of the first cabinet body 7 or the second cabinet body 8.

[0150] It can be understood that the storage compartment is used to store items to be refrigerated or frozen. When the door 1 of the refrigerator closes the storage compartment, the door 1 of the refrigerator is in the closed state, and the side of the cabinet door 2 is at a first distance (close to zero) relative to the hinge 9 of the refrigeration equipment. For example, the side of the cabinet door 2 and the side of the door 1 of the refrigerator are flush. At this time, the cabinet door 2 can completely block the door 1 of the refrigerator, ensuring that the cabinet door 2 of the refrigeration equipment exposed in the accommodation space is consistent with the surrounding first cabinet body 7 and second cabinet body 8 in appearance.

[0151] When the door 1 of the refrigerator opens the storage compartment, the door 1 of the refrigerator is in the open state, and the side of the cabinet door 2 is at a second distance (the second distance is greater than the first distance) relative to the hinge 9 of the refrigeration equipment. For example, the side of the cabinet door 2 and the side of the door 1 of the refrigerator are misaligned, and a gap is formed that can accommodate the side of the first cabinet body 7 or the second cabinet body 8, so as to avoid the collision or interference between the cabinet door 2 and the first cabinet body 7 or the second cabinet body 8 caused by the opening of the door 1 of the refrigerator.

[0152] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered by the scope of the claims of the present invention.
