[0055] The following is combined with Figures 1 - 11, the door body assembly and the refrigeration equipment provided by the utility model embodiment are described in detail through specific embodiments and their application scenarios.

[0056] In the first aspect, as Figure 1 , Figure 6 , Figure 7 and Figure 9 shown, the present utility model provides a door body assembly, which is applied to a refrigeration equipment, and includes: a box door 1, a cabinet door 2, a sliding module 4, a sliding door mechanism 6 and a hanging structure 5;

[0057] The box door 1 is configured to be rotatably arranged on the box body 3 of the refrigeration equipment through at least two hinges 9, 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 drivingly connected to move in opposite directions relative to the slide rail 41;

[0058] 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 a clamping head 51 and a clamping seat 52, the clamping head 51 and the clamping seat 52 are respectively arranged on the first sliding member 42 and the cabinet door 2, and the clamping head 51 and the clamping seat 52 are clamped and magnetically attracted;

[0059] Wherein, 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.

[0060] It can be understood that the door body assembly is applied to refrigeration equipment such as refrigerators and freezers. The box body 3 of the refrigeration equipment is provided with hinges 9, and the box door 1 is rotatably connected to the box body 3 through the hinges 9 to realize the opening or closing of the box door 1 relative to the box body 3. The 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 equipment is consistent with the surrounding cabinet body, so that the coordination between the refrigeration equipment and the surrounding environment is better.

[0061] 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.

[0062] 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 track, and the adapter seat of the first slider 42 is connected to the supporting member of the hanging structure 5; the ball bracket of the second slider 43 is slidably arranged on the second track, and the adapter seat of the second slider 43 is connected to the sliding door mechanism 6.

[0063] 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.

[0064] 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. In this design, when the second slider 43 moves in the extending direction of the slide rail 41 towards the first direction, the second slider 43 will drive the first slider 42 to move in the extending direction of the slide rail 41 towards the second direction, 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.

[0065] 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 towards the side close to the hinge 9 along the width direction of the box door 1, the first slider 42 will drive the cabinet door 2 to move towards the side away from the hinge 9 along the width direction of the box door 1 through the hanging structure 5; conversely, when the sliding door mechanism 6 drives the second slider 43 to move towards the side away from the hinge 9 along the width direction of the box door 1, the first slider 42 will drive the cabinet door 2 to move towards the side close to the hinge 9 along the width direction of the box door 1 through the hanging structure 5.

[0066] For the hanging structure 5, the clamping head 51 can be detachably installed on the first slider 42 through locking parts such as bolts and rivets, or the clamping head 51 can also be integrally formed with the first slider 42; correspondingly, the clamping seat 52 can be detachably installed on the cabinet door 2 through locking parts such as bolts and rivets. Of course, the clamping head 51 can also be arranged on the cabinet door 2, and correspondingly, the clamping seat 52 is arranged on the first slider 42.

[0067] At the same time, the clamping seat 52 is provided with clamping structures such as a clamping opening and a clamping cavity, and the clamping head 51 is clamped in the clamping structure of the clamping seat 52; a magnetic attraction component is arranged between the clamping head 51 and the clamping seat 52, or at least part of the clamping head 51 and the clamping seat 52 are made of permanent magnets, so that when the clamping head 51 and the clamping seat 52 are clamped, the clamping head 51 and the clamping seat 52 are magnetically attracted to ensure the reliable connection between the clamping head 51 and the clamping seat 52.

[0068] By arranging a sliding module 4 and a hanging structure 5 between the cabinet door 1 and the door 2, and configuring a sliding door mechanism 6 for pulling the second slider 43 of the sliding module 4, when installing the door 2, the clamping head 51 and the clamping seat 52 of the hanging structure 5 can be respectively arranged on the first slider 42 of the sliding module 4 and the 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, and then the clamping head 51 and the clamping seat 52 are clamped together. By using the magnetic attraction between the clamping head 51 and the clamping seat 52, it is ensured that the clamping head 51 and the clamping seat 52 are reliably connected as a whole, so as to conveniently realize the installation of the door 2; during the process of opening or closing the cabinet door 1, by the sliding door mechanism 6 pulling the second slider 43 to move relative to the slide rail 41, the first slider 42 can move along the slide rail 41 in opposite directions, thereby ensuring that the door 2 can move relative to the cabinet door 1 in the width direction of the cabinet door 1.

[0069] 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, by using the door 2 to move relative to the cabinet door 1 in the width direction, it can be avoided that the door 2 touches the surrounding cabinets during the opening and closing process of the cabinet door 1, meeting the normal opening and closing requirements of the cabinet door 1 of the refrigeration equipment.

[0070] In some embodiments, as Figure 2 、 Figure 3 and Figure 5 shown, a first magnetic member 501 is provided on the clamping head 51, and a second magnetic member 502 is provided on the clamping seat 52, and the first magnetic member 501 and the second magnetic member 502 attract each other.

[0071] It can be understood that when the clamping head 51 and the clamping seat 52 are clamped, the first magnetic member 501 and the second magnetic member 502 approach each other, and the first magnetic member 501 and the second magnetic member 502 attract each other to prevent the clamping head 51 from disengaging from the clamping seat 52.

[0072] Optionally, both the first magnetic member 501 and the second magnetic member 502 are permanent magnets. For example, the permanent magnet is a neodymium iron boron magnet. This design is more convenient for realizing the magnetic adsorption between the clamping head 51 and the clamping seat 52 compared with an electromagnet.

[0073] Wherein, the pole of the end of the first magnetic member 501 facing the second magnetic member 502 is different from the pole of the end of the second magnetic member 502 facing the first magnetic member 501, so that the first magnetic member 501 and the second magnetic member 502 attract each other.

[0074] Optionally, when the magnetic attraction force between the first magnetic member 501 and the second magnetic member 502 meets the installation requirements of the cabinet door 2, one of the first magnetic member 501 and the second magnetic member 502 is a permanent magnet, and the other is a ferromagnetic member. This design does not require considering the polarity of the first magnetic member 501 and the second magnetic member 502 during installation, improving the installation convenience.

[0075] In some examples, the first magnetic member 501 can be a ferromagnetic member, and the second magnetic member 502 can be a permanent magnet.

[0076] In practical applications, when the card joint 51 is made of iron or steel, and the card socket 52 is made of plastic, the entire card joint 51 can be used as a ferromagnetic member. In this case, there is no need to install the first magnetic member 501 on the card joint 51, and only the second magnetic member 502 needs to be installed on the card socket 52.

[0077] In some embodiments, such as Figure 2 、 Figure 3 and Figure 5 shown, the card joint 51 has a card tongue 510, the card socket 52 has a card slot 520, the card tongue 510 is opposite to the card slot 520 along the thickness direction of the cabinet door 2, and can be engaged with the card slot 520.

[0078] It can be understood that the card joint 51 can be provided on the side of the first sliding member 42 facing the cabinet door 2, and the card socket 52 is correspondingly provided on the side of the cabinet door 2 facing the sliding member. When installing the cabinet door 2, only by controlling the cabinet door 2 to move towards the box door 1 along the thickness direction, the card tongue 510 can be engaged in the card slot 520 along the thickness direction.

[0079] Since the card joint 51 and the card socket 52 can achieve magnetic attraction, when the card tongue 510 is engaged with the card slot 520, the card tongue 510 and the card slot 520 can be configured as an interference fit or can be engaged according to a set size, and no specific limitation is made thereto.

[0080] In some examples, such as Figure 5 and Figure 6 shown, the structures of the card tongue 510 and the card slot 520 are adapted to each other and both extend along the width direction of the box door 1. When the card tongue 510 is engaged with the card slot 520, the card tongue 510 is vertically limited between the upper side wall and the lower side wall of the card slot 520.

[0081] Among them, the cross-sectional shape of the card tongue 510 in the vertical plane can be an isosceles trapezoid, a rectangle, etc.

[0082] In some embodiments, such as Figure 5As shown, in order to facilitate the magnetic attraction between the card connector 51 and the card socket 52, the first magnetic member 501 is provided on the tongue 510, and the second magnetic member 502 is provided in the card slot 520.

[0083] Specifically, when the card connector 51 is provided on one side of the first sliding member 42 facing the cabinet door 2, and the card socket 52 is provided on one side of the cabinet door 2 facing the first sliding member 42, the tongue 510 extends along the thickness direction of the cabinet door 2. The first magnetic member 501 is provided at one end of the tongue 510 facing the cabinet door 2. The notch of the card slot 520 faces the box door 1, and the second magnetic member 502 is provided on the bottom surface of the card slot 520.

[0084] In this way, when the tongue 510 is engaged in the card slot 520, the first magnetic member 501 and the second magnetic member 502 are close to or in contact with each other. This design is beneficial to ensure the reliability of the attraction between the first magnetic member 501 and the second magnetic member 502.

[0085] In some embodiments, as Figure 5 and Figure 6 shown, the groove wall of the card slot 520 is provided with a guiding surface, and the guiding surface is in sliding fit with the tongue 510 to guide the tongue 510 into the card slot 520; the first magnetic member 501 and the second magnetic member 502 are used to drive the tongue 510 into the card slot 520.

[0086] It can be understood that the first magnetic member 501 can be provided on the tongue 510, and the second magnetic member 502 can be correspondingly provided in the card slot 520. Then, when the guiding surface guides the tongue 510 into the card slot 520, the first magnetic member 501 and the second magnetic member 502 approach each other, and the magnetic attraction between the first magnetic member 501 and the second magnetic member 502 gradually increases to drive the tongue 510 into the card slot 520.

[0087] Since the card slot 520 has a notch end and a bottom end, it can be set that from the notch end to the bottom end, the opening width of the card slot 520 gradually decreases. This design can make the groove wall of the card slot 520 automatically form a guiding surface (bevel surface) inclined to the thickness direction of the cabinet door 2; since the structure of the tongue 510 and the card slot 520 are adapted to each other, this design also facilitates controlling the tongue 510 to be directly inserted into the card slot 520 along the thickness direction.

[0088] In some embodiments, as Figure 3 and Figure 4 shown, the card socket 52 includes a socket body 521 and a fixing ear 522. The socket body 521 and the fixing ear 522 are connected. The card slot 520 is provided in the socket body 521, and the fixing ear 522 is connected to the cabinet door 2.

[0089] It is understandable that the fixing ear 522 is provided with mounting holes, 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 holes.

[0090] Furthermore, as Figure 4 shown, 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 clamping seat body 521.

[0091] Optionally, at least two fixing ears 522 can be provided, and at least one fixing ear 522 is arranged on the upper side of the clamping seat body 521 along the height direction of the cabinet door 2.

[0092] For example, three fixing ears 522 are provided, one of the fixing ears 522 is arranged on the upper side of the clamping seat body 521 along the height direction of the cabinet door 2, and the other two fixing ears 522 are arranged on the left and right sides of the clamping seat body 521 along the width direction.

[0093] In some embodiments, in order to ensure that the cabinet door 2 is reliably installed on the box door 1, a plurality of clamping heads 51 are provided on the first sliding member 42, and a plurality of clamping seats 52 are provided on the clamping seat 52; the plurality of clamping heads 51 are arranged along the width direction and are arranged in one-to-one correspondence with the plurality of clamping seats 52. At the same time, when any set of clamping heads 51 and clamping seats 52 arranged oppositely are clamped, magnetic attraction can be achieved.

[0094] 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, and the sliding door mechanism 6 is connected to the second sliding member 43 of one of the plurality of sets of sliding modules 4.

[0095] 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, 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.

[0096] In some embodiments, as Figure 1 and Figure 9 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.

[0097] It is understandable 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, and at this time, there is no decorative member at the notch end of the groove 101.

[0098] In some application scenarios, if the cabinet door 2 is no longer installed on the outer side of the box door 1, the sliding module 4 is no longer used at this time. By covering the decorative part on the notch end of the groove 101, the hidden design of the sliding module 4 can be realized, ensuring the aesthetic appearance of the box door 1.

[0099] In some embodiments, as Figure 7 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.

[0100] It can be understood that the traction arm is bent, and the first end of the traction 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 traction 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.

[0101] During the opening process of the box door 1, the traction arm drives the second sliding member 43 to move toward the side close to the hinge 9, and then the first sliding member 42 drives the cabinet door 2 to move 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.

[0102] During the closing process of the box door 1, the traction arm drives the second sliding member 43 to move away from the side of the hinge 9, and then the first sliding member 42 drives the cabinet door 2 to move toward 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.

[0103] In some embodiments, as Figure 11 shown, the sliding door mechanism 6 includes: a trigger and a linear drive; the trigger is used to obtain the opening and closing signal of the box door 1; the linear drive is arranged between the box door 1 and the second sliding member 43 and is connected to the trigger; wherein, the linear drive 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 trigger.

[0104] It can be understood that in order to facilitate controlling the working state of the linear drive according to the opening and closing signal fed back by the trigger, the trigger can be electrically connected to the control module, and the control module is electrically connected to the linear drive.

[0105] The trigger can be a photoelectric switch, and the photoelectric switch 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 trigger 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;

[0106] The linear drive member can be a telescopic rod such as a cylinder or an electric push rod. The linear drive member extends along the width direction, a first end of the linear drive member is connected to the door 1, and a second end of the linear drive member is connected to the second sliding member 43.

[0107] Taking the triggering member as an angle sensor as an example, the control of the cabinet door 2 by the linear drive member during the opening and closing process of the cabinet door 1 is described in detail as follows.

[0108] 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.

[0109] 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.

[0110] In some embodiments, 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.

[0111] It is understandable that the coupling component 44 includes a first drawstring and a second drawstring. The first drawstring is wound around the first end of the slide rail 41, and the second drawstring is wound around the second end of the slide rail 41. The first drawstring, the first sliding member 42, the second drawstring, 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.

[0112] In some examples, such as Figure 8 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.

[0113] 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 opposite to each other.

[0114] When the second sliding member 43 drives the second rack 443 to move along the slide rail 41 toward the side close to the hinge 9, the second rack 443 will drive the coupling gear 442 to rotate. Then, based on the meshing setting between the coupling gear 442 and the first rack 441, the first rack 441 drives the first sliding member 42 to move toward 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.

[0115] In a second aspect, as Figure 9 , Figure 10 and Figure 11 shown, the embodiment of the present utility model 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.

[0116] 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.

[0117] 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 cabinet 3 of 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 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 of the box door 1 is flush with the side of the cabinet door 2.

[0118] Since the refrigeration device includes a door body component, and the specific structure of the door body component refers to the above embodiment, the refrigeration device shown in this embodiment includes all the technical solutions of the above embodiment. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above embodiment, which will not be elaborated here one by one.

[0119] In some embodiments, as Figure 10 and Figure 11 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 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 avoids the first cabinet 7 or the second cabinet 8.

[0120] It can be understood that there is an opening 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 closer to 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.

[0121] 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 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.

[0122] 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 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.

[0123] In this embodiment, the cabinet door 2 is movably arranged outside the door 1 of the box along the width direction of the door 1 of the box, and the sliding door mechanism 6 is used to drive the cabinet door 2 to move relative to the door 1 of the box during the opening or closing of the door 1 of the box, so that the door 1 of the box 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 box rotates, and can meet 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 equipment to better integrate into the home environment, achieving the effects of overall beauty and sealing.

[0124] In some embodiments, as Figure 10 and Figure 11 shown, 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 relative to the door 1 of the box between a first position and a second position along the width direction; in the case where 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; in the case where 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 is away from the hinge 9, and the sides of the cabinet door 2 and the door 1 of the box are offset to avoid the side wall of the first cabinet body 7 or the second cabinet body 8.

[0125] 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 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 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 equipment is consistent with the surrounding first cabinet body 7 and second cabinet body 8 in appearance.

[0126] When the door 1 of the box opens the storage compartment, the door 1 of the box 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 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 due to the opening of the door 1 of the box.

[0127] 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.
