[0061] Combine the following Figures 1 - 11 , the door body assembly and refrigeration equipment provided by the utility model embodiment are described in detail through specific embodiments and their application scenarios.

[0062] In the first aspect, Figure 1 , Figure 4 , Figure 7 and Figure 9 As shown, the utility model provides a door assembly, which is applied to refrigeration equipment, including: a box door 1, a cabinet door 2, a sliding module 4, a sliding door mechanism 6 and a hanging structure 5;

[0063] The cabinet door 1 is rotatably arranged on the cabinet body 3 of the refrigeration equipment, and the cabinet door 2 is arranged on the side of the cabinet door 1 away from the cabinet body 3; 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 arranged on the cabinet door 1 and extends along the width direction of the cabinet door 1; the first slide member 42 and the second slide member 43 are movably arranged on the slide rail 41 respectively, and the first slide member 42 and the second slide member 43 are transmission-connected to move in the opposite direction relative to the slide rail 41;

[0064] The sliding door mechanism 6 is configured to be disposed on the box body 3 and connected to the second sliding member 43, so as 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 is disposed between the first sliding member 42 and the cabinet door 2, and the first sliding member 42 is detachably connected to the cabinet door 2 through the hanging structure 5;

[0065] Among them, 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.

[0066] It is understandable that the door body assembly is applied to refrigeration devices such as refrigerators and freezers. A hinge 9 is provided on the cabinet body 3 of the refrigeration device, and the cabinet door 1 is rotatably connected to the cabinet body 3 through the hinge 9 to realize the opening or closing of the cabinet door 1 relative to the cabinet body 3. A cabinet door 2 is provided on the outer side of the cabinet door 1. The cabinet door 2 can be a door panel. 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.

[0067] 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.

[0068] The structures of the first sliding member 42 and the second sliding member 43 are the same, and both include a connected ball bracket and an adapter seat. The ball bracket of the first sliding member 42 is slidably arranged on the first track. The ball bracket and the adapter seat of the first sliding member 42 are connected, and the adapter seat of the first sliding member 42 is detachably connected to the cabinet door 2 through the hanging structure 5. The ball bracket of the second sliding member 43 is slidably arranged on the second track. The ball bracket and the adapter seat of the second sliding member 43 are connected, and the adapter seat of the second sliding member 43 is connected to the sliding door mechanism 6.

[0069] The hanging structure 5 can be configured as a first component and a second component capable of realizing hanging. The first component is arranged on the first sliding member 42, and the second component is arranged on the cabinet door 2.

[0070] The sliding door mechanism 6 can be a link mechanism or a telescopic mechanism provided between the cabinet body 3 and the cabinet door 1. There is no specific limitation on this, 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 cabinet door 1.

[0071] 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. This design can make the second sliding member 43 drive the first sliding member 42 to move in the second direction along the extension direction of the slide rail 41 when the second sliding member 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 sliding member 43 moves in the second direction, it will drive the first sliding member 42 to move in the first direction.

[0072] 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 along the width direction of the cabinet door 1 towards the side close to the hinge 9, the first sliding member 42 will drive the cabinet door 2 to move along the width direction of the cabinet 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 sliding member 43 to move along the width direction of the cabinet door 1 towards the side away from the hinge 9, the first sliding member 42 will drive the cabinet door 2 to move along the width direction of the cabinet door 1 towards the side close to the hinge 9 through the hanging structure 5.

[0073] 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, 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, and then the first sliding member 42 is connected to the cabinet door 2 through the hanging structure 5, so as to conveniently realize the installation of the cabinet door 2; this cabinet door installation method is convenient to operate, reduces the labor intensity of the installers, and improves the installation efficiency of the cabinet door.

[0074] Furthermore, 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 be used to pull the second sliding member 43 to move relative to the slide rail 41, so that the first sliding member 42 can move in the opposite direction along the slide rail 41, and then the first sliding member 42 drives the cabinet door 2 to move left and right relative to the cabinet door 1 along 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.

[0075] In some embodiments, as Figure 4 shown, the hanging structure 5 includes a supporting member 511 and a first lapping portion 512. The supporting member 511 is arranged on the first sliding member 42, and the first lapping portion 512 is arranged on the cabinet door 2. The supporting member 511 is lapped with the first lapping portion 512 to support the cabinet door 2.

[0076] It can be understood that the supporting member 511 can be detachably arranged on the first sliding member 42 through locking members such as bolts and rivets, or the supporting member 511 and the first sliding member 42 can be integrally formed; the first lapping portion 512 can be a hanging groove or a bayonet arranged on the cabinet door 2. Under the action of the gravity of the cabinet door 2, the supporting member 511 can be quickly and reliably lapped on the first lapping portion 512.

[0077] In some embodiments, as Figure 4 shown, the first lapping portion 512 includes a hanging groove, and the supporting member 511 is hung in the hanging groove and supported on the lower side of the upper groove wall of the hanging groove.

[0078] It can be understood that the hanging groove serves as a fulcrum for connecting the supporting member 511 with the cabinet door 2. The supporting member 511 has at least a hook 5212 extending vertically upward, and the hook 5212 can be extended into the hanging groove. Under the action of the gravity of the cabinet door 2, the hook 5212 will automatically abut against the lower side of the upper groove wall of the hanging groove, thereby realizing the convenient use of the supporting member 511 to complete the installation of the cabinet door 2.

[0079] In some embodiments, Figure 2 and Figure 4 As shown, in order to reduce the installation gap between the box door 1 and the cabinet door 2, the supporting member 511 is arranged on a side of the first sliding member 42 facing the cabinet door 2, and the hanging groove is arranged on a side of the cabinet door 2 facing the first sliding member 42.

[0080] In some embodiments, Figure 3 As shown, in order to ensure the stability of the cabinet door 2 installed on the box door 1, the first sliding member 42 is provided with multiple supporting members 511, and the cabinet door 2 is provided with multiple hanging grooves; the multiple supporting members 511 are arranged along the width direction and are arranged one by one opposite to the multiple hanging grooves.

[0081] In this way, using multiple supporting members 511 to support the cabinet door 2 can ensure that the cabinet door 2 is subjected to balanced force, and can stably move relative to the cabinet door 1 under the drive of the first sliding member 42. Among them, the multiple supporting members 511 can be configured to be distributed at the same height, so that under the support of the multiple supporting members 511, the top surface or bottom surface of the cabinet door 2 is ensured to be arranged parallel to the horizontal plane.

[0082] In some embodiments, Figure 3 and Figure 4 As shown, the supporting member 511 includes a connecting portion 5111 and a supporting portion 5112; the connecting portion 5111 is connected to the first sliding member 42, and the supporting portion 5112 is connected to the connecting portion 5111 and is spaced apart from the first sliding member 42 to be hung in the hanging groove.

[0083] It can be understood that the connecting portion 5111 and the supporting portion 5112 can form a hook 5212-like structure, and at least one of the connecting portion 5111 and the supporting portion 5112 can be abutted against the upper side groove wall of the hanging groove up and down to support the cabinet door 2, and the supporting portion 5112 and the groove wall of the hanging groove can also be abutted along the thickness direction of the cabinet door 2 to prevent the supporting member 511 from detaching from the hanging groove.

[0084] In some embodiments, Figure 4As shown, the supporting portion 5112 is arranged on the upper side of the connecting portion 5111 along the height direction of the cabinet door 2; the hanging groove includes a first groove body 5121 and a second groove body 5122; the first groove body 5121 is used for the supporting member 511 to extend into, and the first groove body 5121 is arranged on a side of the cabinet door 2 facing the first sliding member 42; the second groove body 5122 is arranged on the upper groove wall of the first groove body 5121, and is adapted to the supporting portion 5112.

[0085] It is understandable that the slot width of the first slot body 5121 along the height direction is greater than the height of the supporting member 511 along the height direction. This design facilitates the supporting member 511 to extend into the hanging slot through the first slot body 5121 along the thickness direction of the cabinet door 2.

[0086] At the same time, when the supporting member 511 is hung in the hanging groove, the supporting part 5112 is inserted into the second groove body 5122 and abuts against the vertical groove wall of the second groove body 5122 along the thickness direction of the cabinet door 2; in this case, the top surface of the connecting part 5111 can be set to abut against the upper groove wall of the first groove body 5121, or the top end of the supporting part 5112 can be set to abut against the upper groove wall of the second groove body 5122.

[0087] In some embodiments, Figure 3 and Figure 4 As shown, the width of the supporting member 511 extending along the width direction is equal to the width of the hanging groove extending along the width direction. This design can ensure that the supporting member 511 is limited between the two vertical groove walls of the hanging groove along the width direction, preventing the cabinet door 2 from shaking relative to the supporting member 511 under the support of the supporting member 511.

[0088] In some embodiments, Figure 3 and Figure 4 As shown, the connecting portion 5111 is extended along the thickness direction of the cabinet door 2 , and the supporting portion 5112 is extended along the height direction of the cabinet door 2 .

[0089] It is understandable that the connecting portion 5111 and the supporting portion 5112 are vertically connected and can be configured as an "L"-shaped structure or a "T"-shaped structure. The supporting member 511 is hung in the hanging groove through the supporting portion 5112, and the connecting portion 5111 and / or the supporting portion 5112 of the supporting member 511 can be configured to be supported on the lower side of the upper groove wall of the hanging groove.

[0090] Specifically, the top surface of the connecting portion 5111 abuts against the upper groove wall of the first groove body 5121, the top surface of the supporting portion 5112 abuts against the upper groove wall of the second groove body 5122, and the side of the supporting portion 5112 toward the cabinet door 2 abuts against the groove wall of the second groove body 5122 away from the cabinet door 2 along the thickness direction of the cabinet door 2.

[0091] In some embodiments, Figure 3As shown, the supporting member 511 further includes a first reinforcing rib 5113, and the first reinforcing rib 5113 is disposed between the connecting portion 5111 and the sliding member. This design can utilize the first reinforcing rib 5113 to ensure the bonding strength between the entire supporting member 511 and the first sliding member 42, and prevent the connection structure between the supporting member 511 and the first sliding member 42 from failing due to excessive force. Among them, multiple first reinforcing ribs 5113 can be provided, and the multiple first reinforcing ribs 5113 are arranged side by side.

[0092] In some embodiments, in order to ensure the structural strength of the supporting member 511, the thicknesses of both the connecting portion 5111 and the supporting portion 5112 are greater than or equal to 2 mm. For example, the thicknesses of the connecting portion 5111 and the supporting portion 5112 are 2 mm, 2.5 mm, 3 mm, or 3.5 mm.

[0093] 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, multiple sets of the sliding module 4 and the hanging structure 5 are respectively provided and are arranged in a one-to-one correspondence. Multiple sets of the sliding module 4 are provided, and the multiple sets of the sliding module 4 are disposed 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 multiple sets of the sliding module 4.

[0094] Specifically, four sets of the sliding module 4 are provided. Among them, two sets of the sliding module 4 are arranged along the width direction of the box door 1 and are disposed between the upper end of the box door 1 and the upper end of the cabinet door 2. The other two sets of the sliding module 4 are arranged along the width direction of the box door 1 and are disposed between the lower end of the box door 1 and the lower end of the cabinet door 2.

[0095] 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 disposed 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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, 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 equipment.

[0101] 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, and 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 equipment either.

[0102] In some embodiments, as Figure 11 shown, the sliding door mechanism 6 includes: a trigger member and a linear drive member; the trigger member is used to obtain the opening and closing signal of the box door 1; the linear drive member is arranged between the box door 1 and the second sliding member 43 and is connected to the trigger member; wherein, the linear drive 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 trigger member.

[0103] It is understandable that in order to facilitate controlling the working state of the linear drive member according to the opening and closing signal fed back by the trigger member, the trigger member can be electrically connected to the control module, and the control module and the linear drive member are electrically connected.

[0104] The trigger 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 trigger 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;

[0105] The linear drive member can be a telescopic rod such as a cylinder or an electric push rod. The linear drive member extends in the width direction. The first end of the linear drive member is connected to the box door 1, and the second end of the linear drive member is connected to the second sliding member 43.

[0106] Taking the trigger member as an angle sensor as an example below, the control of the cabinet door 2 by the linear drive member during the opening and closing process of the box door 1 will be specifically described as follows.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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 sequentially connected end to end to form a ring structure. 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.

[0111] Some examples include Figure 8As 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 disposed on the slide rail 41 and is respectively engaged 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.

[0112] It can be understood that the coupling gear 442 is rotatably disposed 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 disposed on both sides of the coupling gear 442. The tooth surfaces of the first rack 441 and the second rack 443 are oppositely arranged.

[0113] When the second slider 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 slider 42 to move toward 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.

[0114] In some embodiments, as Figure 1 and Figure 5 shown, the hanging structure 5 may also be configured to include a hanging member 521 and a second overlapping portion 522. The hanging member 521 is disposed on the cabinet door 2, and the second overlapping portion 522 is disposed on the first slider 42. The hanging member 521 is hung on the second overlapping portion 522.

[0115] It can be understood that for the hanging structure 5 of this embodiment, the hanging member 521 is detachably installed on the cabinet door 2 through locking members such as bolts and rivets. The second overlapping portion 522 may be a hanging groove or a bayonet disposed on the first slider 42. The hanging member 521 is quickly and reliably hung on the second overlapping portion 522 under the gravity of the cabinet door 2.

[0116] In this way, in practical applications, the hanging member 521 can be installed on the cabinet door 2, and then the hanging member 521 is hung on the second overlapping portion 522 on the first slider 42, so as to conveniently realize the installation of the cabinet door 2; during the process of opening or closing the box door 1, the second slider 43 is driven to move relative to the slide rail 41 through the sliding door mechanism 6, which can make the first slider 42 move along the slide rail 41 in the opposite direction, thereby ensuring that the cabinet door 2 moves relative to the box door 1 along the width direction of the box door 1 under the support of the support member 511.

[0117] When the refrigeration device is used in an embedded installation relative to the cabinet, this design can also utilize the movement of the cabinet door 2 relative to the box door 1 in the width direction during the process of opening or closing the box door 1, avoiding the cabinet door 2 from touching the surrounding cabinet during the opening and closing of the box door 1, and meeting the normal opening and closing requirements of the box door 1 of the refrigeration device.

[0118] In some embodiments, as Figure 5 and Figure 6 shown, the hanging member 521 includes a fixed seat 5211 and a hook 5212. The fixed seat 5211 is provided on the cabinet door 2 and is connected to the hook 5212; the second overlapping portion 522 includes a hanging interface, and the hook 5212 is hung on the hanging interface.

[0119] It can be understood that one end of the hook 5212 is in a hook shape and is hung in the hanging interface, and the other end of the hook 5212 is connected to the fixed seat 5211; the fixed seat 5211 is detachably connected to the cabinet door 2 through a locking member. Among them, the hanging member 521 can be an integral metal part composed of the fixed seat 5211 and the hook 5212.

[0120] In order to ensure that the hanging member 521 can be adjustably installed on the cabinet door 2, the fixed seat 5211 is provided with a plurality of mounting holes, and the fixed seat 5211 is connected to the cabinet door 2 through a locking member passing through the mounting holes; among them, at least one of the plurality of mounting holes extends in a first direction, and the first direction is perpendicular or inclined to the width direction.

[0121] It can be understood that the first direction is parallel to the surface of the cabinet door 2, which enables the hanging member 521 to adjust the installation position on the surface of the cabinet door 2. In practical applications, the hanging member 521 can be initially fixed on the cabinet door 2 through a locking member passing through one of the plurality of mounting holes, then the hanging member 521 is hung on the second overlapping portion 522, and the installation position of the hanging member 521 is adjusted. After the installation position of the hanging member 521 is adjusted, the hanging member 521 is fixed through a locking member passing through other mounting holes.

[0122] Among them, the plurality of mounting holes at least include a first round hole, a strip hole and a second round hole; the first round hole, the strip hole and the second round hole are arranged along the width direction, and the strip hole extends along the first direction.

[0123] In some embodiments, as Figure 6 shown, the hanging member 521 further includes a second reinforcing rib 5213. The second reinforcing rib 5213 is provided between the fixed seat 5211 and the hook 5212. This design can utilize the second reinforcing rib 5213 to ensure the bonding strength between the fixed seat 5211 and the hook 5212, and prevent the connection structure between the fixed seat 5211 and the hook 5212 from failing due to excessive force.

[0124] Among them, a plurality of second reinforcing ribs 5213 may be provided, and the plurality of second reinforcing ribs 5213 are arranged side by side.

[0125] In some embodiments, in order to ensure the structural strength of the hanging member 521, the thickness of the hanging member 521 may also be set to be greater than or equal to 2 mm. For example, the thickness of the hanging member 521 is 2 mm, 2.5 mm, 3 mm or 3.5 mm.

[0126] In some embodiments, as Figure 5 shown, the hanging interface includes a first opening area 5221 and a second opening area 5222; the first opening area 5221 and the second opening area 5222 are communicated, the first opening area 5221 is arranged above the second opening area 5222 along the height direction of the cabinet door 1; the opening width of the first opening area 5221 is greater than the opening width of the second opening area 5222, and the opening width of the second opening area 5222 is adapted to the width of the hook 5212, and the hook 5212 is hung on the lower edge of the second opening area 5222.

[0127] It can be understood that when hanging the hanging member 521 into the hanging interface, first extend the hook 5212 of the hanging member 521 into the first opening area 5221 along the thickness direction of the cabinet door 2, and then control the hook 5212 to move from the first opening area 5221 to the second opening area 5222 along the height direction until the hook 5212 is hung on the lower edge of the second opening area 5222 under the gravity of the cabinet door 2.

[0128] Since the opening width of the first opening area 5221 is greater than the width of the hook 5212, the hook 5212 of the hanging member 521 can be conveniently extended into the first opening area 5221; since the opening width of the second opening area 5222 is adapted to the width of the hook 5212, when the hook 5212 is hung on the lower edge of the second opening area 5222, the side wall of the hook 5212 and the side wall of the second opening area 5222 will abut against each other along the width direction of the cabinet door 1, and the hook 5212 will be limited to the second opening area 5222 in a vertically distributed hanging posture, ensuring the stability of the hanging posture of the hanging member 521.

[0129] In a second aspect, as Figure 9 、 Figure 10 and Figure 11 shown, the 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 cabinet door 1 is rotatably arranged on the box body 3 to open or close the storage compartment.

[0130] It is understandable that the cabinet 3 can be provided with multiple storage compartments, which are arranged in sequence from top to bottom along the height direction of the cabinet 3. The cabinet 3 is configured with a set of door components for controlling the opening and closing state of each storage compartment. Among them, the cabinet 3 is provided with hinges 9 on one side corresponding to each storage compartment, and the cabinet 3 can be rotatably connected to the door 1 of the door component corresponding to the storage compartment through the hinges 9.

[0131] For each set of door components, since the cabinet door 2 can move left and right relative to the door 1 in the width direction, when the refrigeration equipment is fully embedded, during the process of opening the door 1, the cabinet door 2 can be controlled to move away from the hinge 9 relative to the door 1 to avoid the cabinet body around the refrigeration equipment; during the process of closing the door 1, the cabinet door 2 is controlled to move closer to the hinge 9 relative to the door 1 until the cabinet door 2 returns to its original position to ensure that the side edges of the door 1 and the cabinet door 2 are flush.

[0132] Since the refrigeration equipment includes door components, and the specific structure of the door components refers to the above embodiments, the refrigeration equipment shown in this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0133] In some embodiments, as Figure 10 and Figure 11 shown, the refrigeration equipment 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 door 1, the sliding door mechanism 6 is used to change the position of the cabinet door 2 on the door 1 so that the cabinet door 2 avoids the first cabinet body 7 or the second cabinet body 8.

[0134] It is understandable that an opening is provided 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 cabinet 3 of the refrigeration equipment to be integrally embedded in the accommodation space. During the process of the 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 side edges of the cabinet door 2 avoid the side walls of the first cabinet body 7 and the second cabinet body 8, prevent the cabinet door 2 from interfering with the side walls of the first cabinet body 7 and the second cabinet body 8, and meet the requirement that the door 1 can be smoothly opened and closed.

[0135] During the process of opening the 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 body 8, enabling the door 1 to be fully opened, which is convenient for users to access items.

[0136] 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 close to the hinge 9. When the box door 1 is completely 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, so that the box door 1 can be completely closed, maintaining the overall aesthetics and sealing performance.

[0137] In this embodiment, the cabinet door 2 is movably arranged outside the box door 1 in 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 body 7 and the second cabinet body 8 on the side during the opening and closing processes, avoiding 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 components 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 aesthetics and sealing.

[0138] In some embodiments, as Figure 10 and Figure 11 shown, the cabinet door 2 can move between a first position and a second position relative to the box door 1 in the width direction; when the cabinet door 2 is in the first position, the box door 1 closes the storage compartment, and the side of the cabinet door 2 facing the hinge 9 is close to the hinge 9; when the cabinet door 2 is in the second position, the box door 1 opens the storage compartment, and the side of the cabinet door 2 facing the hinge 9 is far from the hinge 9, and the side of the cabinet door 2 and the side of the box door 1 are misaligned to avoid the side wall of the first cabinet body 7 or the second cabinet body 8.

[0139] It can be understood that the storage compartment is used to store items to be refrigerated or frozen. When the box door 1 closes the storage compartment, the box door 1 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 box door 1 are flush. At this time, the cabinet door 2 can completely cover the box door 1, 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 the second cabinet body 8 in appearance.

[0140] When the box door 1 opens the storage compartment, the box door 1 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 box door 1 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 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 box door 1.

[0141] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model, rather than to limit it. Although the present utility model 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 utility model do not depart from the spirit and scope of the technical solutions of the present utility model, and should all be covered within the scope of the claims of the present utility model.
