[0054] The following is combined with Figures 1 - 10, the door body assembly and the refrigeration device provided by the embodiments of the utility model are described in detail through specific embodiments and their application scenarios.

[0055] In the first aspect, as Figure 1 , Figure 5 and Figure 8 shown, the embodiments of the present utility model provide a door body assembly, which is applied to a refrigeration device, and includes: a box door 1, a cabinet door 2, a sliding module 4, a sliding door mechanism 6 and a hanging structure 5;

[0056] The box door 1 is rotatably arranged on the box body 3 of the refrigeration device, and the cabinet door 2 is arranged on the side of the box door 1 away from the box body 3; the sliding module 4 includes a slide rail 41, a first sliding member 42 and a second sliding member 43. The slide rail 41 is arranged on the box door 1 and extends along the width direction of the box door 1; the first sliding member 42 and the second sliding member 43 are respectively movably arranged on the slide rail 41, and the first sliding member 42 and the second sliding member 43 are in transmission connection to move in the opposite direction relative to the slide rail 41;

[0057] The sliding door mechanism 6 is configured to be arranged on the box body 3 and connected to the second sliding member 43 to drive the second sliding member 43 to move along the slide rail 41 during the opening and closing process of the box door 1; the hanging structure 5 includes an elastic chuck 51 and a clamping seat 52. The elastic chuck 51 and the clamping seat 52 are respectively arranged on the first sliding member 42 and the cabinet door 2. The elastic chuck 51 can be deformed under the extrusion of the clamping seat 52 and then be clamped with the clamping seat 52;

[0058] Among them, the thickness of the box door 1 is 18 - 60 mm. For example, the thickness of the box door 1 can be 18 mm, 25 mm, 35 mm, 50 mm, 55 mm or 60 mm; the thickness of the cabinet door 2 is 12 - 26 mm. For example, the thickness of the cabinet door 2 can be 12 mm, 15 mm, 20 mm or 26 mm.

[0059] It can be understood that the door body assembly is applied to refrigeration devices such as refrigerators and freezers. A hinge 9 is provided on the box body 3 of the refrigeration device, and the box door 1 is rotatably connected to the box body 3 through the hinge 9 to realize the opening or closing of the box door 1 relative to the box body 3. A cabinet door 2 is arranged on the outer side of the box door 1. The cabinet door 2 can be a door panel, and the cabinet door 2 and the surrounding cabinet body can adopt the same material to ensure that the appearance of the refrigeration device is consistent with the surrounding cabinet body, making the coordination between the refrigeration device and the surrounding environment better.

[0060] 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 track and a second track arranged side by side. The first sliding member 42 is movably arranged on the first track, and the second sliding member 43 is movably arranged on the second track.

[0061] The structures of the first sliding member 42 and the second sliding member 43 are the same, both including a ball bracket and an adapter seat connected to each other; the ball bracket of the first sliding member 42 is slidably disposed on the first track, and the adapter seat of the first sliding member 42 is connected to the elastic chuck 51 or the clamping seat 52 of the hanging structure 5; the ball bracket of the second sliding member 43 is slidably disposed on the second track, and the adapter seat of the second sliding member 43 is connected to the sliding door mechanism 6.

[0062] The sliding door mechanism 6 can be a link mechanism or a telescopic mechanism disposed between the box body 3 and the box door 1, and no specific limitation is made thereto, as long as it can drive the second sliding member 43 to move along the slide rail 41 during the opening and closing process of the box door 1.

[0063] A linkage structure can be provided on the slide rail 41 to realize the transmission connection between the first sliding member 42 and the second sliding member 43. With this design, when the second sliding member 43 moves in the extension direction of the slide rail 41 towards the first direction, the second sliding member 43 will drive the first sliding member 42 to move in the extension direction of the slide rail 41 towards the second direction, and the second direction is opposite to the first direction; conversely, when the second sliding member 43 moves in the second direction, it will drive the first sliding member 42 to move in the first direction.

[0064] Since the first sliding member 42 and the second sliding member 43 move in opposite directions relative to the slide rail 41, when the sliding door mechanism 6 drives the second sliding member 43 to move towards the side close to the hinge 9 in the width direction of the box door 1, the first sliding member 42 will drive the cabinet door 2 to move towards the side away from the hinge 9 in the width direction of the box door 1 through the hanging structure 5; conversely, when the sliding door mechanism 6 drives the second sliding member 43 to move towards the side away from the hinge 9 in the width direction of the box door 1, the first sliding member 42 will drive the cabinet door 2 to move towards the side close to the hinge 9 in the width direction of the box door 1 through the hanging structure 5.

[0065] For the hanging structure 5, the elastic chuck 51 and the clamping seat 52 can be relatively disposed in the width direction of the box door 1 or the thickness direction of the cabinet door 2 to achieve clamping; the clamping seat 52 has clamping structures such as a clamping notch and a clamping cavity adapted to the elastic chuck 51, and the elastic chuck 51 can be embedded into the clamping structure to achieve the clamping between the elastic chuck 51 and the clamping seat 52.

[0066] Meanwhile, to ensure reliable clamping between the elastic chuck 51 and the clamping seat 52, the hardness of the clamping seat 52 is greater than that of the elastic chuck 51. For example, the elastic chuck 51 can be a plastic chuck, and the clamping seat 52 is made of a stainless steel seat. Under the extrusion of the clamping seat 52, the elastic chuck 51 can expand or contract, so that when the elastic chuck 51 is clamped with the clamping seat 52, an interference fit is achieved between the elastic chuck 51 and the clamping seat 52, thereby preventing the elastic chuck 51 from detaching from the clamping seat 52. And this design facilitates the installation and disassembly of the elastic chuck 51 and the clamping seat 52, and will not cause damage to the elastic chuck 51 or the clamping seat 52 during the installation and disassembly process.

[0067] As can be seen from the above, by arranging 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 elastic chuck 51 and the clamping seat 52 of the hanging structure 5 can be respectively arranged on the first sliding member 42 of the sliding module 4 and the cabinet door 2 in advance, and then the slide rail 41 of the sliding module 4 is connected to the cabinet door 1 to realize the installation of the sliding module 4. Then, the clamping seat 52 is used to squeeze the elastic chuck 51 to clamp the elastic chuck 51 and the clamping seat 52 into one body, so as to conveniently complete the installation of the cabinet door 2. This cabinet door installation method is easy to operate, reduces the labor intensity of the installers, and improves the installation efficiency of the cabinet door.

[0068] Furthermore, in practical applications, when the refrigeration equipment is installed in an embedded manner relative to the cabinet, 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 can move along the slide rail 41 in the opposite direction. Furthermore, the first sliding member 42 drives the cabinet door 2 to move relative to the cabinet door 1 in the width direction of the cabinet door 1 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.

[0069] In some embodiments, as Figure 1 、 Figure 2 and Figure 5 shown, the elastic chuck 51 and the clamping seat 52 are arranged opposite to each other in the thickness direction of the cabinet door 2 and can be clamped in the thickness direction. This design can minimize the installation gap between the cabinet door 1 and the cabinet door 2 as much as possible.

[0070] Among them, the elastic chuck 51 and the first sliding member 42 can be integrally formed, and the clamping seat 52 can be detachably connected to the cabinet door 2 through locking members such as bolts and rivets.

[0071] Of course, in this embodiment, the snap seat 52 can also be provided on the side surface of the first sliding member 42 facing the cabinet door 2, and the elastic snap head 51 can be provided on the side surface of the cabinet door 2 facing the first sliding member 42.

[0072] In some embodiments, as Figure 5 shown, the elastic snap head 51 and the snap seat 52 are oppositely arranged along the thickness direction of the cabinet door 2 and can be snapped along the thickness direction.

[0073] It can be understood that since the elastic snap head 51 and the snap seat 52 are oppositely arranged along the thickness direction of the cabinet door 2, the snap seat 52 can be controlled to approach the elastic snap head 51 along the thickness direction, so as to use the snap seat 52 to squeeze the elastic snap head 51 until the elastic snap head 51 deforms and is snapped into the snap structure of the snap seat 52.

[0074] In some embodiments, as Figure 3 and Figure 5 shown, the snap seat 52 has a snap groove 520, and the elastic snap head 51 can contract under the extrusion of the snap groove 520 and then be snapped into the snap groove 520.

[0075] It can be understood that since the snap groove 520 is provided on the snap seat 52, when the elastic snap head 51 and the snap seat 52 are oppositely arranged along the width direction of the cabinet door 1 or the thickness direction of the cabinet door 2, the notch of the snap groove 520 faces the elastic snap head 51 along the above width direction or thickness direction.

[0076] The snap groove 520 can be configured as a circular groove, and the elastic snap head 51 can be switched from the first state to the second state under the extrusion of the snap groove 520; when the elastic snap head 51 is in the first state, the maximum outer diameter of the elastic snap head 51 is greater than the inner diameter of the snap groove 520; when the elastic snap head 51 is in the second state, the maximum outer diameter of the elastic snap head 51 is equal to the inner diameter of the snap groove 520.

[0077] In this way, under the extrusion of the snap groove 520, the elastic snap head 51 will gradually contract until it is snapped into the snap groove 520. At this time, the side wall of the elastic snap head 51 abuts against the groove wall of the snap groove 520, and there is a relatively large contact friction force between the side wall of the elastic snap head 51 and the groove wall of the snap groove 520, which can prevent the elastic snap head 51 from disengaging from the snap groove 520 based on this contact friction force.

[0078] Of course, in this embodiment, snap structures such as grooves 101 and protrusions can also be provided on the groove wall of the snap groove 520. When the elastic snap head 51 contracts under the extrusion of the snap groove 520, it can also be snapped with the snap structure, thereby effectively preventing the elastic snap head 51 from disengaging from the snap groove 520.

[0079] In some embodiments, as Figure 2As shown, the elastic chuck 51 includes a base 511 and a deformable portion 512; the first end of the base 511 is provided on the first slider 42 or the cabinet door 2, the second end of the base 511 is connected to the deformable portion 512, and the deformable portion 512 is used for being clamped in the clamping groove 520.

[0080] It can be understood that the base 511 can be a rigid seat body. For example, the base 511 is an iron seat body or a copper seat body. This design facilitates the reliable fixation of the base 511 on the first slider 42 or the cabinet door 2, and the elastic chuck 51 can play a supporting role on the clamping seat 52 based on the base 511. Among them, both the base 511 and the deformable portion 512 can extend into the clamping groove 520, which enables the base 511 to be supported on the top groove wall of the clamping groove 520.

[0081] At the same time, the deformable portion 512 can be made of plastic or rubber. When the deformable portion 512 is inserted into the clamping groove 520, since the maximum outer diameter of the deformable portion 512 is greater than the inner diameter of the clamping groove 520, the deformable portion 512 will gradually contract under the extrusion of the groove wall of the clamping groove 520 until the maximum outer diameter of the deformable portion 512 is adapted to the inner diameter of the clamping groove 520, so as to realize clamping the deformable portion 512 in the clamping groove 520.

[0082] Furthermore, the deformable portion 512 includes a plurality of petal-shaped protrusions, and the plurality of petal-shaped protrusions are arranged at intervals along the circumferential direction on the base 511; among them, the plurality of petal-shaped protrusions can approach each other under the extrusion of the clamping groove 520, and then be clamped in the clamping groove 520.

[0083] It can be understood that the base 511 is columnar, and the plurality of petal-shaped protrusions are circumferentially evenly distributed relative to the central axis of the base 511 at the second end of the base 511, and each petal-shaped protrusion is petal-shaped. For example, when there are four petal-shaped protrusions, the shape of each petal-shaped protrusion can be 1 / 4 of the columnar body.

[0084] Since the petal-shaped protrusions are separated from each other, each petal-shaped protrusion has a relatively good elastic modulus relative to the base 511. This makes that when the elastic chuck 51 is in the first state, the circumferential distance between any two adjacent petal-shaped protrusions is the first distance; when the elastic chuck 51 is in the second state, the circumferential distance between any two adjacent petal-shaped protrusions is the second distance, and the second distance is less than the first distance. In this way, under the extrusion of the clamping groove 520, the plurality of petal-shaped protrusions will approach each other, that is, the elastic chuck 51 can contract under the extrusion of the clamping groove 520, and then be clamped in the clamping groove 520.

[0085] In some embodiments, such as Figure 3 and Figure 4As shown, in order to facilitate guiding the elastic chuck 51 to contract and deform under the extrusion of the clamping groove 520, the clamping groove 520 includes a guiding section 5201 and a clamping section 5202; the guiding section 5201 and the clamping section 5202 are connected; the guiding section 5201 is used to guide the elastic chuck 51 into the clamping groove 520 and move towards the clamping section 5202; the clamping section 5202 is used to clamp the elastic chuck 51.

[0086] It can be understood that the guiding section 5201 can be configured with an inclined surface or an arc surface to guide the elastic chuck 51 into the clamping groove 520 based on the inclined surface or the arc surface; the clamping section 5202, as the part for clamping the elastic chuck 51, when the elastic chuck 51 is clamped to the clamping section 5202, the elastic chuck 51 undergoes contraction deformation, and the peripheral wall of the elastic chuck 51 abuts against the groove wall corresponding to the clamping section 5202.

[0087] Further, in order to facilitate guiding the elastic chuck 51 into the elastic chuck 51 and ensure that the elastic chuck 51 undergoes contraction deformation during the process of entering the clamping section 5202, it can be set that the first end of the guiding section 5201 is for the elastic chuck 51 to enter, the second end of the guiding section 5201 is connected to one end of the clamping section 5202; the inner diameter of the guiding section 5201 gradually decreases from the first end to the second end.

[0088] Wherein, the guiding section 5201 and the clamping section 5202 are coaxially arranged, the maximum outer diameter of the elastic chuck 51 in the first state is smaller than the inner diameter of the first end of the guiding section 5201 and larger than the inner diameter of the second end of the guiding section 5201.

[0089] In some embodiments, as Figure 3 、 Figure 4 and Figure 5 shown, the clamping seat 52 includes a seat body 521 and a fixing ear 522, the seat body 521 and the fixing ear 522 are connected, and the clamping groove 520 is arranged on the seat body 521; when the elastic chuck 51 is arranged on the first sliding member 42, the fixing ear 522 is connected to the cabinet door 2.

[0090] Specifically, the fixing ear 522 is provided with a mounting hole, and the fixing ear 522 can be fixed to the cabinet door 2 by a locking bolt or a locking screw passing through the mounting hole.

[0091] Further, in order to ensure that the clamping seat 52 is reliably fixed to the cabinet door 2, the clamping seat 52 can be provided with a plurality of fixing ears 522, and the plurality of fixing ears 522 are arranged around the seat body 521.

[0092] Optionally, the fixing ear 522 can be provided with at least two, and at least one fixing ear 522 is arranged on the upper side of the seat body 521 along the height direction of the cabinet door 2.

[0093] For example, there are three fixed ears 522. One of the fixed ears 522 is arranged on the upper side of the card seat body 521 along the height direction of the cabinet door 2, and the other two fixed ears 522 are arranged on the left and right sides of the card seat body 521 along the width direction.

[0094] In some embodiments, in order to ensure that the cabinet door 2 is reliably installed on the box door 1, a plurality of elastic latches 51 may be provided on the first sliding member 42, and a plurality of latch seats 52 are provided; the plurality of elastic latches 51 are arranged along the width direction and are arranged in one-to-one correspondence with the plurality of latch seats 52.

[0095] In some embodiments, as Figure 1 shown, in order to ensure the stability and reliability of the movement of the cabinet door 2 relative to the box door 1, a plurality of sets of sliding modules 4 and hanging structures 5 are respectively provided and are arranged in one-to-one correspondence. A plurality of sets of sliding modules 4 are provided, and the plurality of 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 member 43 of one of the plurality of sets of sliding modules 4.

[0096] Specifically, four sets of sliding modules 4 are provided. Two of the 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. 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.

[0097] In some embodiments, as Figure 1 and Figure 8 shown, the box door 1 is provided with a groove 101, and the sliding module 4 is arranged in the groove 101; the door body assembly further includes a decorative member, and the decorative member cover is used to cover the notch end of the groove 101.

[0098] It can be understood that when the cabinet door 2 is installed on the outer side of the box door 1, the sliding module 4 on the box door 1 is connected to the cabinet door 2 through the hanging structure 5. At this time, there is no decorative member at the notch end of the groove 101.

[0099] In some application scenarios, if the cabinet door 2 is no longer installed on the outer side of the box door 1, at this time the sliding module 4 is no longer used. By covering the notch end of the groove 101 with the decorative member, a hidden design of the sliding module 4 can be realized to ensure the aesthetic appearance of the box door 1.

[0100] In some embodiments, as Figure 6 shown, the sliding door mechanism 6 includes: a traction arm, the first end of the traction arm is configured to be rotatably connected to the box body 3, and the second end of the traction arm is rotatably connected to the second sliding member 43.

[0101] It is understandable that the towing arm is bent, and the first end of the towing arm is rotatably connected to the support on the box body 3. The support is arranged on one side of the hinge 9 between the box door 1 and the box body 3. This design can utilize the power when the box door 1 is opened and closed to force the towing arm to drive the second sliding member 43 to move relative to the slide rail 41 during the opening and closing process of the box door 1.

[0102] During the opening process of the box door 1, the towing arm drives the second sliding member 43 to move towards the side close to the hinge 9. Then, the first sliding member 42 drives the cabinet door 2 to move towards the side away from the hinge 9 in the width direction through the hanging structure 5, so that the cabinet door 2 avoids the cabinet on the side of the refrigeration device.

[0103] During the closing process of the box door 1, the towing arm drives the second sliding member 43 to move towards the side away from the hinge 9. Then, the first sliding member 42 drives the cabinet door 2 to move towards the side close to the hinge 9 in the width direction through the hanging structure 5 until the cabinet door 2 returns to the initial position. And during the reset process of the cabinet door 2, the cabinet door 2 will not touch the cabinet on the side of the refrigeration device either.

[0104] In some embodiments, as Figure 9 and Figure 10 shown, the sliding door mechanism 6 includes: a triggering member and a linear driving member; the triggering member is used to obtain the opening and closing signal of the box door 1; the linear driving member is arranged between the box door 1 and the second sliding member 43 and is connected to the triggering member; wherein, the linear driving member is used to drive the second sliding member 43 to move along the slide rail 41 according to the opening and closing signal fed back by the triggering member.

[0105] It is understandable that in order to facilitate controlling the working state of the linear driving member according to the opening and closing signal fed back by the triggering member, the triggering member can be electrically connected to the control module, and the control module is electrically connected to the linear driving member.

[0106] The triggering member can be a photoelectric switch, which judges the opening and closing state of the box door 1 by detecting the distance change of the box door 1 relative to the box body 3. The triggering member can also be an angle sensor, which judges the opening and closing state of the box door 1 by detecting the angle change of the box door 1 relative to the box body 3;

[0107] The linear driving member can be a telescopic rod such as a cylinder or an electric push rod. The linear driving member extends in the width direction. The first end of the linear driving member is connected to the box door 1, and the second end of the linear driving member is connected to the second sliding member 43.

[0108] Taking the triggering member as an angle sensor as an example below, the control of the cabinet door 2 by the linear driving member during the opening and closing process of the box door 1 will be specifically described as follows.

[0109] In actual application, the angle sensor is installed on the hinge shaft corresponding to the hinge 9 to monitor the rotation state of the cabinet door 1 relative to the hinge shaft. When the cabinet door 1 is opened, the angle sensor feeds back the door opening signal to the linear drive, and the linear drive drives the second sliding member 43 to move along the width direction toward the direction close to the hinge 9; 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 along the width direction of the cabinet door 1 toward the side away from the hinge 9 through the hanging structure 5; when the cabinet door 1 is closed, the angle sensor feeds back the door closing signal to the linear drive, and the linear drive drives the second sliding member 43 to move along the width direction toward the direction away from the hinge 9, and then the first sliding member 42 drives the cabinet door 2 to move along the width direction toward the side close to the hinge 9 through the hanging structure 5.

[0110] Furthermore, as the opening or closing amplitude of the door 1 is different, the angle sensor can also obtain the rotation angle of the door 1, and the linear drive component can determine the preset value of movement according to the rotation angle. In the process of opening the door 1, the travel of the telescopic end of the linear drive component is determined according to the rotation angle of the door 1 when it is opened, and then the linear drive component drives the cabinet door 2 to move a preset distance in the direction away from the hinge 9 through the sliding module 4 to avoid interference between the cabinet door 2 and the external cabinet body; correspondingly, in the process of closing the door 1, the travel of the telescopic end of the linear drive component is determined according to the rotation angle of the door 1 when it is closed, and then the linear drive component drives the cabinet door 2 to move a preset distance in the direction close to the hinge 9 through the sliding module 4 to avoid interference between the cabinet door 2 and the external cabinet body, and finally the cabinet door 2 is reset.

[0111] In some embodiments, Figure 6 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.

[0112] It is understandable that the coupling assembly 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, the second pull rope is wound around the second end of the slide rail 41, and the first pull rope, the first sliding member 42, the second pull rope and the second sliding member 43 are connected end to end in sequence to form a ring structure. In this way, when the sliding door mechanism 6 pulls the first sliding member 42 to move along the slide rail 41, the first sliding member 42 and the second sliding member 43 move in opposite directions relative to the slide rail 41.

[0113] Some examples include Figure 7As 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 slider 42, and the second rack 443 is connected to the second slider 43.

[0114] It can be understood 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.

[0115] When the second slider 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 between the coupling gear 442 and the first rack 441, the first rack 441 drives the first slider 42 to move towards the side away from the hinge 9, so as to realize the reverse movement of the first slider 42 and the second slider 43 relative to the slide rail 41.

[0116] In a second aspect, as Figure 8 、 Figure 9 and Figure 10 shown, the embodiment of the present utility model further provides a refrigeration device, including: a box body 3 and the door body assembly 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.

[0117] It can be understood that the box body 3 can be provided with multiple storage compartments, and the multiple storage compartments are arranged in sequence 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 the 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.

[0118] For each set of door body assemblies, 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 relative to the box door 1 towards the side away from the hinge 9 to avoid the cabinet around the refrigeration device; during the process of closing the box door 1, the cabinet door 2 can be controlled to move relative to the box door 1 towards the side close to the hinge 9 until the cabinet door 2 returns to its original position to ensure that the side of the box door 1 is flush with the side of the cabinet door 2.

[0119] Since the refrigeration device includes a door body assembly, and the specific structure of the door body assembly refers to the above-mentioned embodiments, the refrigeration device shown in this embodiment includes all the technical solutions of the above-mentioned embodiments. Therefore, it has at least all the beneficial effects achieved by all the technical solutions of the above-mentioned embodiments, which will not be elaborated here one by one.

[0120] In some embodiments, as Figure 9 and Figure 10 shown, the refrigeration device is configured to be disposed in the accommodation space between the first cabinet 7 and the second cabinet 8; during the opening or closing process of 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 avoids the first cabinet 7 or the second cabinet 8.

[0121] It can be understood that an opening is provided on the outer side of the accommodation space between the first cabinet 7 and the second cabinet 8, and this design enables 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 in the width direction away from or towards the hinge 9. This design can ensure that the cabinet door 2 avoids the side walls of the first cabinet 7 and the second cabinet 8, preventing the cabinet door 2 from interfering with the side walls of the first cabinet 7 and the second cabinet 8, and meeting the requirement that the box door 1 can be smoothly opened and closed.

[0122] During the process of opening the box door 1, the sliding door mechanism 6 drives the cabinet door 2 to move a preset distance in the width direction away from one side of the hinge 9. In this way, the cabinet door 2 can smoothly avoid the side wall of the second cabinet 8, enabling the box door 1 to be fully opened, which is convenient for users to access items.

[0123] 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 in the width direction towards the side of the hinge 9. 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 7, enabling the box door 1 to be fully closed, maintaining the overall aesthetics and sealing performance.

[0124] In this embodiment, the cabinet door 2 is movably disposed on the outside of the box door 1 along the width direction of the box door 1, and the sliding door mechanism 6 is used to drive the cabinet door 2 to move relative to the box door 1 during the opening or closing process of the box door 1, so that the box door 1 can avoid the first cabinet 7 and the second cabinet 8 on the side during the opening and closing processes, preventing interference between the cabinet door 2 and the outside when the box door 1 rotates, and meeting the usage requirements of users in different scenarios. This design not only improves the convenience of use but also can avoid possible damage to the door body assembly during use. At the same time, this design also enables the refrigeration device to better integrate into the home environment, achieving the effects of overall aesthetics and sealing.

[0125] In some embodiments, asFigure 9 and Figure 10 As shown in Figure 10 , the door 1 of the box is rotatably connected to the box body 3 through a hinge 9, and the cabinet door 2 can move between a first position and a second position along the width direction relative to the door 1 of the box; when the cabinet door 2 is in the first position, the door 1 of the box 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 box opens the storage compartment, and the side of the cabinet door 2 facing the hinge 9 moves away from the hinge 9, and the side of the cabinet door 2 and the side of the door 1 of the box are offset to avoid the side walls of the first cabinet body 7 or the second cabinet body 8.

[0126] It can be understood that the storage compartment is used to store items to be refrigerated or frozen. When the door 1 of the box closes the storage compartment, the door 1 of the box is in a 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 device. For example, the side of the cabinet door 2 and the side of the door 1 of the box are flush. At this time, the cabinet door 2 can completely cover the door 1 of the box, ensuring that the cabinet door 2 of the accommodation space exposed by the refrigeration device is consistent with the surrounding first cabinet body 7 and the second cabinet body 8 in appearance.

[0127] When the door 1 of the box opens the storage compartment, the door 1 of the box is in an 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 device. For example, the side of the cabinet door 2 and the side of the door 1 of the box are offset, 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 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 box.

[0128] 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.
