[0071] The following combination Figures 1 - 13, the door body assembly and refrigeration equipment provided by the utility model embodiment are described in detail through specific embodiments and their application scenarios.

[0072] In the first aspect, Figure 1 , Figure 2 , Figure 3 and Figure 7 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;

[0073] The cabinet door 1 is rotatably arranged on the cabinet body 3 of the refrigeration device through at least two hinges 9, and the cabinet door 2 is arranged on the side of the cabinet door 1 away from the cabinet body 3;

[0074] The sliding module 4 includes a slide rail 41, a first slide member 42 and a second slide member 43. The slide rail 41 is provided on the door 1 and extends along the width direction of the door 1. The first slide member 42 and the second slide member 43 are movably provided on the slide rail 41 respectively. 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.

[0075] 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 process of opening and closing the box door 1;

[0076] The hanging structure 5 includes a locking tongue 51 and a locking member 52, which are respectively arranged on the first sliding member 42 and the cabinet door 2, and the locking member 52 has a locking groove 520, and the locking tongue 51 is inserted into the locking groove 520 and is locked and connected with the locking member 52 through the locking structure;

[0077] Among them, the locking structure can be a locking pin locking structure, a bolt locking structure or a snap-on structure; 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.

[0078] It is understandable that the door assembly is applied to refrigeration equipment such as refrigerators and freezers, and a hinge 9 is provided on the box body 3 of the refrigeration equipment, 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. The outer side of the box door 1 is provided with a cabinet door 2, which can be a door panel, and the cabinet door 2 and the surrounding cabinets can be made of the same material to ensure that the appearance of the refrigeration equipment is consistent with the surrounding cabinets, so that the refrigeration equipment is better coordinated with the surrounding environment.

[0079] For the sliding module 4, the slide rail 41 can be a parallel rail well-known in the art, that is, the slide rail 41 includes a first rail and a second rail arranged side by side. The first slider 42 is movably arranged on the first rail, and the second slider 43 is movably arranged on the second rail.

[0080] The first slider 42 and the second slider 43 have the same structure, both including a connected ball bracket and an adapter seat; the ball bracket of the first slider 42 is slidably arranged on the first rail, and the adapter seat of the first slider 42 is connected to the locking tongue 51 of the hanging structure 5; the ball bracket of the second slider 43 is slidably arranged on the second rail, and the adapter seat of the second slider 43 is connected to the sliding door mechanism 6.

[0081] 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.

[0082] A linkage structure can be provided on the slide rail 41 to realize the transmission connection between the first slider 42 and the second slider 43. This design can make the second slider 43 drive the first slider 42 to move in the second direction along the extension direction of the slide rail 41 when the second slider 43 moves in the first direction along the extension direction of the slide rail 41, and the second direction is opposite to the first direction; conversely, when the second slider 43 moves in the second direction, it will drive the first slider 42 to move in the first direction.

[0083] 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 toward 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 away from the hinge 9 along the width direction through the hanging structure 5; conversely, when the sliding door mechanism 6 drives the second slider 43 to move away from the hinge 9 along the width direction, the first slider 42 will drive the cabinet door 2 to move toward the side close to the hinge 9 along the width direction through the hanging structure 5.

[0084] For the hanging structure 5, the locking tongue 51 can be arranged on the first slider 42, and the locking member 52 is correspondingly arranged on the cabinet door 2; the locking tongue 51 can also be arranged on the cabinet door 2, and the locking member 52 is correspondingly arranged on the first slider 42.

[0085] The locking tongue 51 is arranged opposite to the locking member 52 along the extension direction of the locking groove 520 so as to insert the locking tongue 51 into the locking groove 520. A suitable clamping structure or other locking structures can be provided between the surface of the locking tongue 51 and the inner wall of the locking groove 520 to realize the locking connection between the locking tongue 51 and the locking member 52, thereby preventing the locking tongue 51 from disengaging from the locking groove 520.

[0086] As can be seen from the above, by providing 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 sliding member 43 of the sliding module 4, when installing the door 2, the lock tongue 51 and the locking member 52 of the hanging structure 5 can be respectively arranged on the sliding member 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 complete the installation of the sliding module 4. Then, the lock tongue 51 is controlled to be inserted into the locking groove 520 of the locking member 52 to achieve the locking connection between the lock tongue 51 and the locking member 52, so as to conveniently complete the installation of the door 2. This door installation method is easy to operate, reduces the labor intensity of the installers, and improves the door installation efficiency.

[0087] 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 moves in the opposite direction along the slide rail 41. Then, the first sliding member 42 drives the door 2 to move left and right relative to the cabinet door 1 in the width direction through the hanging structure 5, avoiding the 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.

[0088] In some embodiments, as Figure 2 and Figure 3 shown, in order to facilitate the locking connection between the lock tongue 51 and the locking member 52, both the lock tongue 51 and the locking groove 520 extend along the first direction, and the lock tongue 51 is inserted into the locking groove 520 along the first direction; wherein, the first direction is the width direction or the thickness direction of the door 2.

[0089] As Figure 2 and Figure 3 shown, the lock tongue 51 can be arranged on the side surface of the first sliding member 42 facing the door 2, and the locking member 52 is correspondingly arranged on the side surface of the door 2 facing the first sliding member 42; in this case, the lock tongue 51 and the locking groove 520 can be arranged opposite to each other along the width direction of the cabinet door 1 or the door 2. This design can minimize the installation gap between the cabinet door 1 and the door 2 as much as possible.

[0090] In some cases, the lock tongue 51 can be arranged at one end of the first sliding member 42 along the width direction, and the locking member 52 is correspondingly arranged on a side of the cabinet door 2 facing the first sliding member 42; in this case, the lock tongue 51 and the locking groove 520 can be arranged relatively to each other along the thickness direction of the cabinet door 2. This design ensures that the installation gap between the box door 1 and the cabinet door 2 is reduced, and it is also convenient for the operator to install the cabinet door 2; in actual application, while ensuring that the lock tongue 51 and the locking groove 520 are relatively to each other along the thickness direction of the cabinet door 2, it is only necessary to push the cabinet door 2 toward the box door 1 along the thickness direction to achieve the locking connection between the lock tongue 51 and the locking member 52, and the operation is simple and convenient.

[0091] In some embodiments, Figure 2 , Figure 4 and Figure 5 As shown, the locking groove 520 has a notch 5211 and an embedding opening 5212; the notch 5211 extends along the first direction and is arranged opposite to the bottom of the locking groove 520; the embedding opening 5212 is arranged at one end of the locking groove 520 along the first direction and is connected to the notch 5211; the locking tongue 51 can be inserted into the locking groove 520 from the embedding opening 5212 along the first direction, and the end of the locking tongue 51 facing away from the bottom of the locking groove 520 is inserted into the notch 5211.

[0092] It is understandable that the first direction shown in this embodiment can be the width direction of the door 1 . In this case, the notch 5211 and the bottom of the locking groove 520 are arranged relatively to each other along the thickness direction of the door 1 .

[0093] When the locking tongue 51 is fixed to the first sliding member 42, the end of the locking tongue 51 away from the bottom of the locking groove 520 is connected to the first sliding member 42. By configuring the notch 5211 and the insertion opening 5212 for the locking groove 520, it is convenient to control the locking tongue 51 to enter the locking groove 520 from the insertion opening 5212 along the width direction, and the locking tongue 51 can be controlled to move relative to the locking groove 520 along the width direction until the locking connection between the locking tongue 51 and the locking member 52 is completed at the set position in the locking groove 520.

[0094] In order to facilitate the insertion of the locking tongue 51 into the locking groove 520, the locking tongue 51 can be configured to be in a cubic shape, and the front end of the locking tongue 51 along the insertion direction can be configured to be in a pointed shape.

[0095] In some embodiments, Figure 5 and Figure 6 As shown, the locking member 52 includes a locking seat 5221 and a fixing ear 5222 , the locking seat 5221 and the fixing ear 5222 are connected, the locking groove 520 is provided on the locking seat 5221 , and the fixing ear 5222 is connected to the cabinet door 2 .

[0096] Specifically, the fixing lug 5222 is provided with a mounting hole, and the fixing lug 5222 can be fixed to the cabinet door 2 by a locking bolt or a locking screw passing through the mounting hole.

[0097] Further, to ensure that the locking member 52 is reliably fixed to the cabinet door 2, the locking member 52 can be provided with a plurality of fixing lugs 5222, and the plurality of fixing lugs 5222 are arranged around the locking seat 5221.

[0098] Optionally, at least two fixing lugs 5222 can be provided, and at least one fixing lug 5222 is arranged on the upper side of the locking seat 5221 along the height direction of the cabinet door 2.

[0099] For example, three fixing lugs 5222 are provided, one of the fixing lugs 5222 is arranged on the upper side of the locking seat 5221 along the height direction of the cabinet door 2, and the other two fixing lugs 5222 are arranged on the left and right sides of the locking seat 5221 along the width direction.

[0100] In some embodiments, as Figure 4 and Figure 5 shown, the locking tongue 51 includes a locking tongue body 511, the locking groove 520 includes a main groove body 5201, and the locking tongue body 511 is inserted into the main groove body 5201; the locking tongue body 511 and the groove wall of the main groove body 5201 are connected by a locking structure.

[0101] It can be understood that the locking structure includes a first locking portion and a second locking portion. The first locking portion is arranged on the surface of the locking tongue body 511, and the second locking portion is arranged on the groove wall of the main groove body 5201; when the locking tongue body 511 is inserted into the main groove body 5201, the first locking portion and the second locking portion are locked and connected, which can prevent the locking tongue body 511 from being detached from the main groove body 5201.

[0102] In some embodiments, as Figure 2 and Figure 3 shown, the locking structure includes: a limiting groove 531 and an elastic member 532; the limiting groove 531 is arranged on the groove wall of the main groove body 5201; the elastic member 532 is arranged on one side surface of the locking tongue body 511 facing the groove wall of the main groove body 5201 and is used for abutting against the groove wall; wherein, the elastic member 532 can move towards the limiting groove 531 under the drive of the locking tongue body 511 until it is locked in the limiting groove 531.

[0103] It can be understood that, as Figure 2 shown, before the locking tongue body 511 is inserted into the main groove body 5201, a part of the elastic member 532 extends towards the groove wall of the main groove body 5201 and interferes with the groove wall of the main groove body 5201; however, since the elastic member 532 is not squeezed by the groove wall of the main groove body 5201, the elastic member 532 is in an initial state.

[0104] During the process of inserting the lock tongue body 511 into the main slot body 5201, due to the small gap between the side of the slot wall of the lock tongue body 511 facing the main slot body 5201 and the slot wall of the main slot body 5201, the elastic member 532 is squeezed by the slot wall of the main slot body 5201 while moving along with the lock tongue body 511 and is in a compressed state.

[0105] When the lock tongue body 511 is fully inserted into the main slot body 5201, the elastic member 532 is embedded in the limiting slot 531, and the elastic member 532 recovers from the compressed state to the initial state. At this time, the elastic member 532 abuts against the slot wall of the limiting slot 531 along the insertion direction (for example, the width direction) of the lock tongue body 511, thereby locking the lock tongue 51 in the locking slot 520 based on the mutual cooperation between the limiting slot 531 and the elastic member 532.

[0106] In some embodiments, Figure 3 As shown, the elastic member 532 includes: an elastic support member 5321 and a guide piece 5322; the elastic support member 5321 is arranged in the receiving groove on the lock tongue body 511; the guide piece 5322 is arranged on the elastic support member 5321, and at least part of the guide piece 5322 can be exposed in the receiving groove and abut against the groove wall of the main groove body 5201; the end of the guide piece 5322 that is away from the insertion direction of the lock tongue 51 is inclined toward one side of the groove wall of the main groove body 5201.

[0107] It is understandable that the elastic support member 5321 can be a spring and is configured to extend along the thickness direction of the cabinet door 2; the elastic support member 5321 can be an elastic sheet or a rigid sheet; one end of the elastic support member 5321 is connected to the bottom of the accommodating groove, and the other end of the elastic support member 5321 is exposed at the notch end of the accommodating groove and is connected to the guide sheet 5322.

[0108] During the process of inserting the lock tongue body 511 into the main slot body 5201, the elastic member 532 is squeezed by the slot wall of the main slot body 5201 and hidden in the accommodating slot, thereby ensuring that the lock tongue body 511 is smoothly inserted into the main slot body 5201; when the lock tongue body 511 is fully inserted into the main slot body 5201, the elastic member 532 is embedded in the limiting slot 531 and abuts against the slot wall of the limiting slot 531.

[0109] At the same time, by configuring an elastic support member 5321 for the guide piece 5322 and setting the guide piece 5322 at an angle, during the process of inserting the lock tongue body 511 into the main groove body 5201, the elastic member 532 can be compressed by the groove wall of the main groove body 5201 under the guidance of the guide piece 5322. The existence of the elastic member 532 will not affect the insertion operation of the lock tongue body 511 into the main groove body 5201, and when the lock tongue body 511 is fully inserted into the main groove body 5201, it can be ensured that the elastic member 532 is embedded in the limiting groove 531 and abuts against the groove wall of the limiting groove 531.

[0110] In some examples, the elastic support member 5321 may also be configured to include a first elastic support foot and a second elastic support foot, and the first elastic support foot and the second elastic support foot are spaced apart on the lock tongue body 511; the guide plate 5322 is disposed between the first elastic support foot and the second elastic support foot.

[0111] It can be understood that the first elastic support foot and the second elastic support foot can be configured to be spaced apart along the width direction of the door 1, the first elastic support foot is located in front of the second elastic support foot along the insertion direction of the lock tongue 51, and the first elastic support foot and the second elastic support foot both extend along the thickness direction of the door 1, but the height of the first elastic support foot extending along the thickness direction is less than the height of the second elastic support foot extending along the thickness direction, so that the end of the guide plate 5322 away from the insertion direction of the lock tongue 51 is inclined toward one side of the groove wall of the main groove body 5201.

[0112] In some embodiments, Figure 4 and Figure 5 As shown, in order to facilitate the smooth insertion of the lock tongue 51 into the locking groove 520, the lock tongue 51 also includes a guide rib 512, which is arranged on the lock tongue body 511 and arranged along the extension direction of the lock tongue body 511; the locking groove 520 also includes a guide groove 5202, which is arranged on the groove wall of the main groove body 5201 and arranged along the extension direction of the main groove body 5201; the guide rib 512 is used to be movably arranged in the guide groove 5202.

[0113] Furthermore, if Figure 4 and Figure 5 As shown, the lock tongue 51 is provided with two guide ribs 512, which are relatively arranged at the upper and lower sides of the lock tongue body 511; the locking groove 520 is provided with two guide grooves 5202, which are relatively arranged at the top groove wall and the bottom groove wall of the locking groove 520, and the two guide ribs 512 and the two guide grooves 5202 are arranged one by one. This design can ensure that the lock tongue 51 and the locking groove 520 are abutted against each other along the thickness direction of the door 1, prevent the lock tongue 51 from being separated from the locking groove 520, and thus ensure the reliability of the locking connection between the lock tongue 51 and the locking member 52.

[0114] In some embodiments, in order to ensure that the cabinet door 2 is reliably installed on the box door 1, a plurality of locking tongues 51 are provided on the first sliding member 42, and a plurality of locking members 52 are provided on the cabinet door 2. The plurality of locking tongues 51 and the plurality of locking members 52 are arranged in a one-to-one correspondence and are all arranged along the height direction of the box door 1. Among them, the locking groove 520 on each locking member 52 extends along the width direction of the box door 1.

[0115] In some embodiments, such as Figure 8 shown, the sliding door mechanism 6 includes: a driving component 61 and a transmission component 62; the first end of the driving component 61 is configured to be rotatably arranged on the box body 3, the second end of the driving component 61 is configured to be rotatably arranged on the box door 1, and the first end of the driving component 61 is arranged offset from the hinge axis between the box body 3 and the box door 1; the transmission component 62 is configured to be arranged between the second end of the driving component 61 and the second sliding member 43;

[0116] During the process of the box door 1 opening or closing the box body 3, the second end of the driving component 61 rotates relative to the box door 1, and then drives the transmission component 62 to drive the second sliding member 43 to move along the width direction of the box door 1.

[0117] It can be understood that since the box door 1 is rotatably connected to the box body 3 through the hinge axis on the hinge 9, a fixed axis can be set at a position deviating from the hinge axis on the hinge 9, and the first end of the driving component 61 can be rotatably arranged on the hinge 9 through the fixed axis.

[0118] When the box door 1 rotates relative to the box body 3 around the hinge axis, the second end of the driving component 61 rotates in a circular motion with the hinge axis as the center. Since the first end of the driving component 61 is arranged offset from the hinge axis, the distance between the first end and the second end of the driving component 61 will change. And the position of the second end of the driving component 61 on the box door 1 is fixedly set, so the box door 1 will drive the second end of the driving component 61 to rotate relative to the box door 1 during the opening and closing process.

[0119] Optionally, the driving component 61 can be a crank mechanism or a connecting rod mechanism.

[0120] The transmission component 62 is used to convert the rotational motion of the driving component 61 into a linear motion, and drive the second sliding member 43 to move left and right relative to the box door 1 along the width direction. Since the first sliding member 42 and the second sliding member 43 move in opposite directions along the slide rail 41, the first sliding member 42 will drive the cabinet door 2 to move in the opposite direction to the second sliding member 43 through the hanging structure 5.

[0121] Optionally, the transmission component 62 can be a crank-slider mechanism or a gear-rack transmission mechanism.

[0122] In practical applications, during the opening process of the cabinet door 1, the cabinet door 1 drives the second end of the driving component 61 to rotate relative to the hinge axis. Based on the misaligned arrangement of the first end of the driving component 61 and the hinge axis, the distance between the first end and the second end of the driving component 61 increases, thereby forcing the second end of the driving component 61 to rotate clockwise relative to the cabinet door 1. Furthermore, it controls the transmission component 62 to drive the cabinet door 2 to move away from the hinge 9 along the width direction of the cabinet door 1, that is, to move to the left relative to the cabinet door 1. In this way, interference between the cabinet door 2 and the side cabinets can be avoided. During the closing process of the cabinet door 1, the cabinet door 1 drives the second end of the driving component 61 to rotate relative to the hinge axis. Based on the misaligned arrangement of the first end of the driving component 61 and the hinge axis, the distance between the first end and the second end of the driving component 61 decreases, driving the second end of the driving component 61 to rotate counterclockwise relative to the cabinet door 1. Furthermore, it controls the transmission component 62 to drive the cabinet door 2 to move towards the hinge 9 along the width direction of the cabinet door 1, that is, to move to the right relative to the cabinet door 1. In this way, it can ensure that the cabinet door 2 can avoid the side cabinets when the cabinet door 1 is closed and reset the cabinet door 2.

[0123] In some embodiments, as Figure 8 shown, the driving component 61 includes: a first connecting rod 611 and a second connecting rod 612; the first end of the first connecting rod 611 is rotatably arranged on the box body 3 and is misaligned with the hinge axis; the first end of the second connecting rod 612 is rotatably connected to the second end of the first connecting rod 611; the second end of the second connecting rod 612 is rotatably arranged on the cabinet door 1 and is connected to the transmission component 62.

[0124] It can be understood that the first connecting rod 611 and the second connecting rod 612 are connected by a hinge axis, the first connecting rod 611 and the second connecting rod 612 can rotate relative to each other, the first connecting rod 611 can rotate relative to the box body 3, and the second connecting rod 612 can rotate relative to the cabinet door 1.

[0125] Since the first end of the first connecting rod 611 is misaligned with the hinge axis, during the opening or closing process of the cabinet door 1, the distance between the second end of the second connecting rod 612 and the first end of the first connecting rod 611 changes, while the position of the second end of the second connecting rod 612 relative to the cabinet door 1 remains unchanged, resulting in the second end of the second connecting rod 612 rotating around the cabinet door 1 and driving the transmission component 62 to drive the cabinet door 2 to move along the width direction of the cabinet door 1.

[0126] In practical applications, during the opening process of the cabinet door 1, the cabinet door 1 drives the second end of the second link 612 to rotate relative to the hinge axis. Based on the misaligned arrangement of the first end of the first link 611 and the hinge axis, the distance between the first end of the first link 611 and the second end of the second link 612 increases, driving the second end of the second link 612 to rotate clockwise relative to the cabinet door 1. Furthermore, it controls the transmission assembly 62 to drive the second sliding member 43 to move towards the direction close to the hinge 9, and then the first sliding member 42 drives the cabinet door 2 to move away from the hinge 9 through the hanging structure 5, that is, move to the left relative to the cabinet door 1. In this way, it can avoid interference between the cabinet door 2 and the side cabinets.

[0127] During the closing process of the cabinet door 1, the cabinet door 1 drives the second end of the second link 612 to rotate relative to the hinge axis. Based on the misaligned arrangement of the first end of the first link 611 and the hinge axis, the distance between the first end of the first link 611 and the second end of the second link 612 decreases, driving the second end of the second link 612 to rotate counterclockwise relative to the cabinet door 1. Furthermore, it controls the transmission assembly 62 to drive the second sliding member 43 to move away from the hinge 9, and then the first sliding member 42 drives the cabinet door 2 to move towards the direction close to the hinge 9 through the hanging structure 5, that is, move to the right relative to the cabinet door 1. In this way, it can ensure that the cabinet door 2 can avoid the cabinet door 2 of the side cabinet body when closing the cabinet door 1 and reset the cabinet door 2.

[0128] In some embodiments, as Figure 8 shown, the transmission assembly 62 includes: a gear set 621 and a rack 622; the gear set 621 includes a first gear and a second gear, the first gear and the second gear are meshed and arranged, and are respectively rotatably arranged on the cabinet door 1; the first gear is coaxially connected to the second end of the driving assembly 61 and can be driven to rotate by the driving assembly 61; the rack 622 is meshed with the second gear, the rack 622 extends along the width direction and is configured to be connected to the second sliding member 43.

[0129] It can be understood that when the cabinet door 1 is opened, the cabinet door 1 drives the second end of the driving assembly 61 to rotate relative to the hinge axis, the distance between the first end and the second end of the driving assembly 61 increases, driving the second end of the driving assembly 61 to rotate clockwise relative to the cabinet door 1. Since the installation position of the gear set 621 on the cabinet door 1 remains unchanged, the second end of the driving assembly 61 drives the first gear to rotate clockwise, and the second gear rotates counterclockwise to drive the rack 622 to drive the second sliding member 43 to move along the width direction of the cabinet door 1 towards the direction close to the hinge 9, and then the first sliding member 42 drives the cabinet door 1 to move away from the hinge 9. In this way, it can avoid interference between the cabinet door 2 and the side cabinets.

[0130] During the closing process of the door 1, the door 1 drives the second end of the driving component 61 to rotate relative to the hinge shaft, and the distance between the first end and the second end of the driving component 61 is reduced, driving the second end of the driving component 61 to rotate counterclockwise relative to the door 1. Since the installation position of the gear set 621 on the door 1 remains unchanged, the second end of the driving component 61 drives the first gear to rotate counterclockwise, and the second gear rotates clockwise, so as to drive the rack 622 to drive the second sliding member 43 to move along the width direction of the door 1 away from the hinge 9, and then the first sliding member 42 drives the door 1 to move toward the hinge 9. In this way, it can be ensured that when the door 1 is closed, the cabinet door 2 can avoid the side cabinet and reset the cabinet door 2.

[0131] In some embodiments, Figure 1 As shown, in order to ensure the stability and reliability of the movement of the cabinet door 2 relative to the box door 1, the sliding module 4 and the hanging structure 5 are respectively provided with multiple sets, and are arranged one by one opposite to each other. The sliding module 4 is provided with multiple sets, and the multiple sets of sliding modules 4 are arranged between the box door 1 and the cabinet door 2. The sliding door mechanism 6 is connected to the second sliding member 43 of one of the multiple sets of sliding modules 4.

[0132] Specifically, four sets of sliding modules 4 are provided, two sets of sliding modules 4 are arranged along the width direction of the box door 1 and are arranged between the upper end of the box door 1 and the upper end of the cabinet door 2, and the other two sets of sliding modules 4 are arranged along the width direction of the box door 1 and are arranged between the lower end of the box door 1 and the lower end of the cabinet door 2.

[0133] In some embodiments, Figure 1 and Figure 10 As 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 also includes a decorative piece, and the decorative piece cover is used to cover the notch end of the groove 101 .

[0134] It is understandable that when the cabinet door 2 is installed on the outside of the cabinet door 1, the sliding module 4 on the cabinet door 1 is connected to the cabinet door 2 through the hanging structure 5, and there is no decorative piece at the notch end of the groove 101. The slide rail 41 of the sliding module 4 is connected to the bottom of the groove 101.

[0135] In some application scenarios, if the cabinet door 2 is no longer installed on the outside of the box door 1, the sliding module 4 is no longer used. By setting a decorative cover on the notch end of the groove 101, the sliding module 4 can be hidden to ensure the aesthetic appearance of the box door 1.

[0136] 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.

[0137] It is understandable that the coupling component 44 includes a first pulling rope and a second pulling rope. The first pulling rope is wound around the first end of the sliding rail 41, and the second pulling rope is wound around the second end of the sliding rail 41. The first pulling rope, the first sliding member 42, the second pulling rope, and the second sliding member 43 are sequentially connected end to end to form an annular structure. In this way, when the sliding door mechanism 6 pulls the first sliding member 42 to move along the sliding rail 41, the moving directions of the first sliding member 42 and the second sliding member 43 relative to the sliding rail 41 are opposite.

[0138] In some examples, as Figure 9 shown, the coupling component 44 includes a first rack 441, a coupling gear 442, and a second rack 443; the coupling gear 442 is rotatably arranged on the sliding 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.

[0139] It is understandable that the coupling gear 442 is rotatably arranged at a set position on the sliding 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.

[0140] When the second sliding member 43 drives the second rack 443 to move along the sliding 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 sliding rail 41.

[0141] In a second aspect, as Figure 10 , Figure 11 , Figure 12 and Figure 13 shown, the embodiment of the present invention 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.

[0142] 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.

[0143] For each set of door body components, since the cabinet door 2 can move left and right relative to the box door 1 in the width direction, when the refrigeration equipment is fully embedded, during the process of opening the box door 1, the cabinet door 2 can be controlled to move away from the hinge 9 relative to the box door 1 to avoid the cabinet body around the refrigeration equipment; during the process of closing the box door 1, the cabinet door 2 can be controlled to move closer to the hinge 9 relative to the box door 1 until the cabinet door 2 returns to its original position, ensuring that the side edges of the box door 1 and the cabinet door 2 are flush.

[0144] Since the refrigeration equipment includes a door body component, and the specific structure of the door body component refers to the above embodiment, the refrigeration equipment 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.

[0145] In some embodiments, as 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 box door 1, the sliding door mechanism 6 is used to change the position of the cabinet door 2 on the box door 1 so that the cabinet door 2 can avoid the first cabinet body 7 or the second cabinet body 8.

[0146] It can be understood that there is an opening on the outer side of the accommodation space between the first cabinet body 7 and the second cabinet body 8, and this design enables the box body 3 of the refrigeration equipment 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 body 7 and the second cabinet body 8, preventing the cabinet door 2 from interfering with the side walls of the first cabinet body 7 and the second cabinet body 8, and meeting the requirement that the box door 1 can be smoothly opened and closed.

[0147] 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 body 8, enabling the box door 1 to be fully opened, which is convenient for users to access items.

[0148] 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 body 7, enabling the box door 1 to be fully closed, maintaining the overall aesthetics and sealing performance.

[0149] In this embodiment, the cabinet door 2 is movably arranged outside the door 1 of the cabinet along the width direction of the door 1 of the cabinet, and the sliding door mechanism 6 is used to drive the cabinet door 2 to move relative to the door 1 of the cabinet during the opening or closing process of the door 1 of the cabinet, so that the door 1 of the cabinet 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 cabinet rotates, and can meet the use requirements of users in different scenarios. This design not only improves the convenience of use, but also can avoid the possible damage of the door assembly during use. At the same time, this design also enables the refrigeration equipment to better integrate into the home environment, achieving the effects of overall beauty and sealing.

[0150] In some embodiments, as Figure 12 and Figure 13 shown, the door 1 of the cabinet is rotatably connected to the cabinet body 3 through a hinge 9, and the cabinet door 2 can move relative to the door 1 of the cabinet 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 cabinet 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 cabinet opens the storage compartment, and the side of the cabinet door 2 facing the hinge 9 is away from the hinge 9. At this time, the side of the cabinet door 2 and the side of the door 1 of the cabinet are misaligned to avoid the side wall of the first cabinet body 7 or the second cabinet body 8.

[0151] It can be understood that the storage compartment is used to store items to be refrigerated or frozen. When the door 1 of the cabinet closes the storage compartment, the door 1 of the cabinet 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 equipment. For example, the side of the cabinet door 2 and the side of the door 1 of the cabinet are flush. At this time, the cabinet door 2 can completely block the door 1 of the cabinet, ensuring that the cabinet door 2 of the refrigeration equipment exposed in the accommodation space is consistent with the surrounding first cabinet body 7 and the second cabinet body 8 in appearance.

[0152] When the door 1 of the cabinet opens the storage compartment, the door 1 of the cabinet 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 equipment. For example, the side of the cabinet door 2 and the side of the door 1 of the cabinet are misaligned, and a gap capable of accommodating the side of the first cabinet body 7 or the second cabinet body 8 is formed, 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 cabinet.

[0153] 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.
