[0064] The following is combined with Figures 1 - 9, the door body assembly and refrigeration equipment provided by the utility model embodiment are described in detail through specific embodiments and their application scenarios.

[0065] In the first aspect, Figures 1 to 3 As shown, the embodiment of 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 and a hanging structure 5;

[0066] The cabinet door 1 is rotatably arranged on the cabinet body 3 of the refrigeration equipment 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; the sliding module 4 includes a slide rail 41 and a slide member 42, the slide rail 41 is arranged on the cabinet door 1 and extends along the width direction of the cabinet door 1; the slide member 42 is movably arranged on the slide rail 41; the hanging structure 5 includes a lock tongue 51 and a locking member 52, the lock tongue 51 and the locking member 52 are respectively arranged on the sliding member 42 and the cabinet door 2, the locking member 52 has a locking groove 520, the lock tongue 51 is inserted into the locking groove 520, and is locked and connected with the locking member 52 through the locking structure;

[0067] Among them, the locking structure can be a locking pin limiting structure, a bolt locking structure, a snap-on structure, etc.; 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.

[0068] 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. A cabinet door 2 is provided on the outside of the box door 1, and the cabinet door 2 can be a door panel, for example, the cabinet door 2 is a wooden door panel or a plastic door panel, and the cabinet door 2 can also be made of the same material as the surrounding cabinets 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.

[0069] For the sliding module 4, the slide rail 41 may be a C-shaped guide rail, the sliding member 42 may be a sliding block, and at least a portion of the sliding member 42 may be movably disposed in a slide groove of the C-shaped guide rail along an extension direction of the C-shaped guide rail.

[0070] For the hanging structure 5 , the locking tongue 51 can be arranged on the sliding member 42 , and the locking member 52 can be 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 can be correspondingly arranged on the sliding member 42 .

[0071] The locking tongue 51 is disposed opposite to the locking member 52 along the extending direction of the locking groove 520 so that the locking tongue 51 is inserted into the locking groove 520. A matching 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 achieve 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.

[0072] As can be seen from the above, by providing the sliding module 4 and the hanging structure 5 between the cabinet door 1 and the cabinet door 2, and the sliding module 4 includes a sliding rail 41 and a sliding member 42 that are slidably arranged, when installing the cabinet door 2, the locking tongue 51 and the locking member 52 of the hanging structure 5 can be respectively arranged on the sliding member 42 and the cabinet door 2 in advance, and then the sliding rail 41 of the sliding module 4 is connected to the cabinet door 1 to achieve the installation of the sliding module 4, and then control the locking tongue 51 to be inserted into the locking groove 520 of the locking member 52 to achieve the locking connection between the locking tongue 51 and the locking member 52, so as to conveniently complete the installation of the cabinet door 2 and realize that the cabinet door 2 can slide left and right relative to the cabinet door 1 in the width direction. 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.

[0073] 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 cabinet door 2 can be moved relative to the cabinet door 1 in the width direction to prevent the cabinet door 2 from touching 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.

[0074] In some embodiments, as Figure 2 and Figure 3 shown, in order to facilitate the locking connection between the locking tongue 51 and the locking member 52, both the locking tongue 51 and the locking groove 520 extend along the first direction, and the locking 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 cabinet door 2.

[0075] As Figure 2 and Figure 3 shown, the locking tongue 51 can be arranged on the side surface of the sliding member 42 facing the cabinet door 2, and the locking member 52 is correspondingly arranged on the side surface of the cabinet door 2 facing the sliding member 42; in this case, the locking 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 cabinet door 2, and this design can minimize the installation gap between the cabinet door 1 and the cabinet door 2 as much as possible.

[0076] In some cases, the lock tongue 51 can be arranged at one end of the 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 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.

[0077] 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.

[0078] 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 .

[0079] When the locking tongue 51 is fixed to the sliding member 42, the end of the locking tongue 51 away from the bottom of the locking groove 520 is connected to the 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.

[0080] 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.

[0081] 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 .

[0082] Specifically, the fixing ear 5222 is provided with mounting holes, and the fixing ear 5222 can be fixed to the cabinet door 2 by a locking bolt or a locking screw passing through the mounting holes.

[0083] Furthermore, in order 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 ears 5222, and the plurality of fixing ears 5222 are arranged around the locking seat 5221.

[0084] Optionally, at least two fixing ears 5222 can be provided, and at least one fixing ear 5222 is arranged on the upper side of the locking seat 5221 along the height direction of the cabinet door 2.

[0085] For example, three fixing ears 5222 are provided, one of the fixing ears 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 ears 5222 are arranged on the left and right sides of the locking seat 5221 along the width direction.

[0086] In some embodiments, as Figure 4 and Figure 5 shown, the lock tongue 51 includes a lock tongue body 511, the locking groove 520 includes a main groove body 5201, and the lock tongue body 511 is inserted into the main groove body 5201; a locking structure is connected between the lock tongue body 511 and the groove wall of the main groove body 5201.

[0087] 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 lock tongue body 511, and the second locking portion is arranged on the groove wall of the main groove body 5201; when the lock tongue body 511 is inserted into the main groove body 5201, the first locking portion and the second locking portion achieve locking connection, which can prevent the lock tongue body 511 from disengaging from the main groove body 5201.

[0088] 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 a side surface of the lock 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 lock tongue body 511 until it is locked in the limiting groove 531.

[0089] It can be understood that, as Figure 2 shown, before the lock 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] In some embodiments, Figure 4 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.

[0099] Furthermore, if Figure 4 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.

[0100] 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 sliding member 42, 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.

[0101] In some embodiments, as Figure 4 shown, the sliding member 42 includes a ball bracket 421 and an adapter seat 422; the ball bracket 421 is movably arranged on the slide rail 41 along the width direction, the adapter seat 422 is connected to the ball bracket 421, the locking tongue 51 is connected to the adapter seat 422, and the locking member 52 is connected to the cabinet door 2.

[0102] It can be understood that the slide rail 41 can be a C-shaped guide rail, and a rolling fit can be achieved between the ball bracket 421 and the slide rail 41 by using balls, so that the sliding member 42 can move smoothly relative to the slide rail 41 without abnormal noise during the movement.

[0103] At the same time, the adapter seat 422 and the ball bracket 421 can be connected by welding, and the adapter seat 422 and the locking tongue 51 can be set as an integral structure, so that the installation of the locking tongue 51 is not required in practical applications, and it is convenient to support the cabinet door 2 by the locking tongue 51.

[0104] Further, along the extending direction of the slide rail 41, the extending length of the ball bracket 421 can be set to be greater than the extending direction of the adapter seat 422. This design can increase the contact area between the ball bracket 421 and the slide rail 41, and reduce the contact friction force between the ball bracket 421 and the slide rail 41, thereby ensuring the stability and reliability of the movement of the sliding member 42 relative to the slide rail 41.

[0105] In some embodiments, as Figure 9 shown, the refrigeration device further includes a sliding door mechanism 6. The sliding door mechanism 6 is arranged on the cabinet body 3 or the box door 1, the sliding door mechanism 6 is connected to the cabinet door 2, and is used to drive the cabinet door 2 to move relative to the box door 1 along the width direction during the opening and closing process of the box door 1; the refrigeration device is configured to be arranged in the accommodation space between the first cabinet body 7 and the second cabinet body 8; during the opening or closing process of the box door 1, the sliding door mechanism 6 is used to change the position of the cabinet door 2 on the box door 1 so that the cabinet door 2 avoids the first cabinet body 7 or the second cabinet body 8.

[0106] It is understandable that an opening is provided on the outer side of the accommodating space between the first cabinet body 7 and the second cabinet body 8. This design enables the cabinet body 3 of the refrigeration device to be integrally embedded into the accommodating space. During the process of the cabinet door 1 passing through the opening to control the opening or closing of the accommodating space, the sliding door mechanism 6 is configured to drive the cabinet door 2 to move in the width direction away from or towards the hinge 9. This design can ensure that the cabinet door 2 avoids the side walls of the first cabinet body 7 and the second cabinet body 8, preventing interference between the side edges of the cabinet door 2 and the side walls of the first cabinet body 7 and the second cabinet body 8, and meeting the requirement for the smooth opening and closing of the cabinet door 1.

[0107] During the process of opening the cabinet door 1, the sliding door mechanism 6 drives the cabinet door 2 to move a preset distance in the width direction towards the side 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 cabinet door 1 to be fully opened, which is convenient for users to access items.

[0108] Similarly, during the process of closing the cabinet 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 cabinet 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 cabinet door 1 to be fully closed, maintaining the overall aesthetics and sealing performance.

[0109] In this embodiment, the cabinet door 2 is movably arranged on the outer side of the cabinet door 1 in the width direction of the cabinet door 1, and the sliding door mechanism 6 is used to drive the cabinet door 2 to move relative to the cabinet door 1 during the opening or closing process of the cabinet door 1, so that the cabinet door 1 can avoid the first cabinet body 7 and the second cabinet body 8 on the side during the opening and closing processes, preventing interference between the cabinet door 2 and the outside when the cabinet door 1 rotates, and meeting the usage requirements of users in different scenarios. This design not only improves the convenience of use but also can avoid possible damage to the door body assembly during use. At the same time, this design also enables the refrigeration device to better integrate into the home environment, achieving the effects of overall aesthetics and sealing.

[0110] In some embodiments, the sliding door mechanism 6 is connected to the sliding member 42 to drive the sliding member 42 to move relative to the slide rail 41 in the width direction of the cabinet door 1.

[0111] It is understandable that during the opening and closing process of the cabinet door 1, the sliding door mechanism 6 drives the sliding member 42 to move relative to the slide rail 41 in the width direction. Since the sliding member 42 is connected to the cabinet door 2 through the hanging structure 5, the sliding door mechanism 6 is used to drive the cabinet door 2 to move relative to the cabinet door 1, ensuring that the cabinet door 2 does not touch the side cabinet body. This design realizes the integration of the sliding door mechanism 6 and the sliding module 4.

[0112] Among them, since there are multiple sliding modules 4, at least one of the multiple sliding modules 4 close to the hinge 9 can be integrally designed with the sliding door mechanism 6.

[0113] In some embodiments, such as Figure 8 and Figure 9 As shown, the box door 1 is rotatably connected to the box body 3 of the refrigeration device through the hinge 9, and the cabinet door 2 can move between a first position and a second position along the width direction relative to the box door 1; 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. At this time, the sides of the cabinet door 2 and the box door 1 are misaligned to avoid the side walls of the first cabinet 7 or the second cabinet 8.

[0114] 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 device. 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 to ensure that the cabinet door 2 of the refrigeration device exposing the accommodation space is consistent with the surrounding first cabinet 7 and second cabinet 8 in appearance.

[0115] 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 device. For example, the side of the cabinet door 2 and the side of the box door 1 are misaligned and form a gap that can accommodate the side of the first cabinet 7 or the second cabinet 8, so as to avoid collision or interference between the cabinet door 2 and the first cabinet 7 or the second cabinet 8 due to the opening of the box door 1.

[0116] In some embodiments, such as Figure 9 As 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 cabinet door 2 and is connected to the trigger; wherein, the linear drive is used to drive the cabinet door 2 to move along the width direction of the box door 1 according to the opening and closing signal fed back by the trigger.

[0117] 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.

[0118] The trigger 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 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;

[0119] 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 cabinet door 1, and the second end of the linear drive member is connected to the cabinet door 2 to drive the cabinet door 2 to move relative to the cabinet door 1 in the width direction.

[0120] Wherein, in the case where the door body assembly includes the above-mentioned sliding module 4 and the hanging structure 5, the linear drive member is arranged on the cabinet door 1. The first end of the linear drive member is connected to the cabinet door 1, and the second end of the linear drive member is connected to the slider 42 of the sliding module 4.

[0121] Taking the trigger member as an angle sensor as an example below, the control of the linear drive member on the cabinet door 2 during the opening and closing of the cabinet door 1 will be specifically described as follows.

[0122] In practical applications, 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 an opening signal to the linear drive member, and the linear drive member drives the cabinet door 2 to move in the width direction of the cabinet door 1 away from the hinge 9; when the cabinet door 1 is closed, the angle sensor feeds back a closing signal to the linear drive member, and the linear drive member drives the cabinet door 2 to move in the width direction of the cabinet door 1 towards the hinge 9.

[0123] Furthermore, as the opening or closing amplitude of the cabinet door 1 is different, the angle sensor can also obtain the rotation angle of the cabinet door 1. The linear drive member can determine the preset value of the movement according to the rotation angle. During the opening process of the cabinet door 1, according to the rotation angle when the cabinet door 1 is opened, the stroke of the telescopic end of the linear drive member is determined, and then the linear drive member drives the cabinet door 2 to move a preset distance away from the hinge 9 to avoid interference between the cabinet door 2 and the external cabinet body; correspondingly, during the closing process of the cabinet door 1, according to the rotation angle when the cabinet door 1 is closed, the stroke of the telescopic end of the linear drive member is determined, and then the linear drive member drives the cabinet door 2 to move a preset distance towards the hinge 9 to avoid interference between the cabinet door 2 and the external cabinet body, and finally the reset of the cabinet door 2 is realized.

[0124] 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 cabinet 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. At least one set of the sliding module 4 is arranged between the upper ends of the cabinet door 1 and the cabinet door 2, and at least one set of the sliding module 4 is arranged between the lower ends of the cabinet door 1 and the cabinet door 2.

[0125] Specifically, there are four sets of sliding modules 4. Two of the sliding modules 4 are arranged along the width direction of the door 1 and are provided between the upper end of the door 1 and the upper end of the cabinet door 2. The other two sets of sliding modules 4 are arranged along the width direction of the door 1 and are provided between the lower end of the door 1 and the lower end of the cabinet door 2.

[0126] In some embodiments, as Figure 1 and Figure 7 shown, the 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 part, and the decorative part cover is used to cover the notch end of the groove 101.

[0127] It can be understood that when the cabinet door 2 is installed on the outer side of the door 1, the sliding module 4 on the door 1 is connected to the cabinet door 2 through the hanging structure 5. At this time, the decorative part is not installed at the notch end of the groove 101. The slide rail 41 of the sliding module 4 is connected to the groove wall of the groove 101.

[0128] In some application scenarios, if the cabinet door 2 is no longer installed on the outer side of the 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 part, a hidden design of the sliding module 4 can be realized to ensure the aesthetic appearance of the door 1.

[0129] In the second aspect, as Figure 7 、 Figure 8 and Figure 9 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 door 1 is rotatably arranged on the box body 3 to open or close the storage compartment.

[0130] It can be understood that the box body 3 can be provided with multiple storage compartments, and the multiple storage compartments are arranged in sequence from top to bottom along the height direction of the box body 3. The box body 3 is configured with a set of door body assemblies for controlling the opening and closing states for each storage compartment. Among them, the box body 3 is provided with a hinge 9 on one side corresponding to each storage compartment, and the box body 3 can be rotatably connected to the door 1 of the door body assembly corresponding to the storage compartment through the hinge 9.

[0131] For each set of door body assemblies, since the cabinet door 2 can move left and right relative to the door 1 along the width direction, when the refrigeration device 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 cabinets around the refrigeration device; during the process of closing the door 1, the cabinet door 2 can be controlled to move toward the side close to the hinge 9 relative to the door 1 until the cabinet door 2 returns to its original position to ensure that the side edge of the door 1 is flush with the side edge of the cabinet door 2.

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

[0133] 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 within the scope of the claims of the present invention.
