In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[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, Figure 1 and Figure 2 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 and a hanging structure 5;

[0066] The cabinet door 1 is configured to be rotatably arranged on the cabinet body 3 of the refrigeration device, and the cabinet door 2 is arranged on a side of the cabinet door 1 away from the cabinet body 3;

[0067] The sliding module 4 includes a sliding rail 41 and a sliding member 42. The sliding rail 41 is arranged on the door 1 and extends along the width direction of the door 1. The sliding member 42 is movably arranged on the sliding rail 41.

[0068] The hanging structure 5 includes a supporting member 51, a hanging member 52, a first locking member 53 and a second locking member 54. The supporting member 51 is arranged on the sliding member 42. The hanging member 52 is configured to be arranged on the cabinet door 2 and movably hung on the supporting member 51. The hanging member 52 is connected to the supporting member 51 through the first locking member 53 and the second locking member 54 respectively.

[0069] The first locking member 53 is used to limit the installation position of the hanging member 52 relative to the supporting member 51 along the height direction of the door 1, and the second locking member 54 is used to limit the installation position of the hanging member 52 relative to the supporting member 51 along the width direction.

[0070] 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. The cabinet door 2 and the surrounding cabinets are 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.

[0071] 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.

[0072] For the hanging structure 5, the hanging member 52 is detachably mounted on the cabinet door 2 by fasteners such as bolts and rivets, and the supporting member 51 can be detachably mounted on the sliding member 42 by fasteners, or can be set as an integrated structure with the sliding member 42; the supporting member 51 can be provided with hanging structures such as hanging grooves and bayonet slots, so that the hanging member 52 can be quickly and reliably hung on the hanging structure under the action of gravity of the cabinet door 2, and can move relative to the supporting member 51 in the width direction and / or height direction.

[0073] Further, both the first locking member 53 and the second locking member 54 can adopt bolts, locking pins, magnetic attracting members, etc. well-known in the art. After the installation position of the hanging member 52 relative to the supporting member 51 is adjusted, the hanging member 52 and the supporting member 51 can be connected into one body through the first locking member 53 and the second locking member 54 respectively, preventing the hanging member 52 from moving relative to the supporting member 51.

[0074] 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, the sliding module 4 includes a sliding rail 41 and a sliding member 42 which are slidably arranged. When installing the cabinet door 2, the sliding rail 41 of the sliding module 4 can be connected to the cabinet door 1 to realize the installation of the sliding module 4. Then, the supporting member 51 is installed on the sliding member 42 of the sliding module 4, the hanging member 52 is installed on the cabinet door 2, and the hanging member 52 is hung on the supporting member 51, so that the installation of the cabinet door 2 can be quickly realized; then, the installation position of the hanging member 52 relative to the supporting member 51 is adjusted along the width direction and the height direction respectively, and the position of the hanging member 52 relative to the supporting member 51 is locked by the first locking member 53 and the second locking member 54, conveniently realizing the adjustment of the installation position of the cabinet door 2 relative to the cabinet door 1 along the width direction and the height direction, and this design also ensures that the cabinet door 2 can move relative to the cabinet door 1 along the width direction of the cabinet door 1.

[0075] Further, 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 utilized to move relative to the cabinet door 1 along the width direction, 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.

[0076] In some embodiments, as Figure 3 and Figure 4 shown, the supporting member 51 is provided with a hanging hole 5101, and the hanging member 52 is movably inserted through the hanging hole 5101 along the width direction and is hung on the supporting member 51 based on the hanging hole 5101; wherein, a part of the hanging member 52 inserted through the hanging hole 5101 is in sliding fit with the supporting member 51 along the height direction.

[0077] It is understandable that the opening shape of the hanging hole 5101 can be circular, rectangular, waist-shaped, oval, etc. The width of the hanging hole 5101 extending in the width direction is greater than the width of the hanging member 52 extending in the width direction. When the hanging member 52 is inserted into the hanging hole 5101, it can move relative to the supporting member 51 in the width direction, thereby changing the hanging position of the hanging member 52 relative to the supporting member 51 in the width direction. After the hanging position of the hanging member 52 relative to the supporting member 51 in the width direction is adjusted, the second locking member 54 distributed in the height direction can be used to lock the hanging member 52 and the supporting member 51 together.

[0078] At the same time, the hanging hole 5101 penetrates the supporting member 51 vertically in the height direction, and a part of the hanging member 52 inserted into the hanging hole 5101 can move relative to the supporting member 51 in the height direction, thereby changing the hanging position of the hanging member 52 relative to the supporting member 51 in the height direction. After the hanging position of the hanging member 52 relative to the supporting member 51 in the height direction is adjusted, the first locking member 53 distributed in the width direction can be used to lock the hanging member 52 and the supporting member 51 together.

[0079] Furthermore, when the hanging member 52 is inserted into the hanging hole 5101, at least part of the hanging member 52 is supported on the upper side of the supporting member 51, so as to ensure that the hanging member 52 is hung on the supporting member 51 based on the hanging hole 5101 and can be used to support the cabinet door 2 connected thereto. Of course, after the hanging position of the hanging member 52 relative to the supporting member 51 in the height direction is adjusted, since the supporting member 51 and the hanging member 52 are locked and connected by the first locking member 53, the first locking member 53 also plays a supporting role for the hanging member 52 with the supporting member 51 as a support.

[0080] Furthermore, the hanging hole 5101 is a strip-shaped hole, the strip-shaped hole extends in the width direction, and the strip-shaped hole is used to guide the movement of the hanging member 52 relative to the supporting member 51 in the width direction. At the same time, the opening width of the strip-shaped hole in the thickness direction of the cabinet door 2 is adapted to the thickness of a part of the hanging member 52 inserted into the strip-shaped hole. This design can ensure that the hanging member 52 can move relative to the supporting member 51 in the height direction, and the hanging member 52 cannot move relative to the supporting member 51 in the thickness direction.

[0081] In some embodiments, as Figure 5 and Figure 6 shown, the hanging member 52 includes: a hook 521 and a fixing seat 522; the hook 521 is movably inserted into the hanging hole 5101 and is hung on the supporting member 51; the fixing seat 522 is connected to the hook 521 and is configured to be detachably connected to the cabinet door 2.

[0082] It is understandable that the hook 521 and the fixing base 522 can be an integral structure. For example, the hook 521 and the fixing base 522 form an integral metal hanging piece or an integral plastic hanging piece.

[0083] The hook 521 is in a hook shape and is vertically downwardly hung on the supporting member 51. Among them, one end of the hook 521 passes through the hanging hole 5101, and the other end of the hook 521 is connected to the fixing base 522.

[0084] Meanwhile, the fixing base 522 can be detachably installed on the cabinet door 2 through locking members such as bolts and rivets.

[0085] Optionally, the fixing base 522 is provided with mounting holes, and the fixing base 522 is installed on the cabinet door 2 through the locking members passing through the mounting holes.

[0086] Optionally, as Figure 1 and Figure 5 shown, the mounting holes include circular holes and oblong holes. The oblong holes extend along the height direction of the cabinet door 2. The diameter of the circular holes is adapted to the diameter of the locking members. The width of the oblong holes extending along the width direction is adapted to the diameter of the locking members. The length of the oblong holes extending along the height direction is greater than the diameter of the locking members. Thus, based on the oblong holes, the mounting position of the hanging member 52 relative to the cabinet door 2 can be adjusted along the height direction, and further the mounting height of the cabinet door 2 relative to the box door 1 can be adjusted.

[0087] Among them, two circular holes can be provided, and the two circular holes are arranged on both sides of the oblong hole along the width direction.

[0088] In some embodiments, as Figure 5 shown, the hook 521 includes: a hook head 5211, a first connecting portion 5212, and a second connecting portion 5213; the hook head 5211 passes through the hanging hole 5101; the first connecting portion 5212 is connected between the hook head 5211 and the fixing base 522, and the second locking member 54 locks between the supporting member 51 and the first connecting portion 5212; the second connecting portion 5213 is connected to the hook head 5211, and the first locking member 53 locks between the supporting member 51 and the second connecting portion 5213.

[0089] It is understandable that the hook head 5211 can be configured to extend along the height direction of the cabinet door 2, the first connecting portion 5212 can be configured as an "L" shaped structure, one end of the first connecting portion 5212 is connected to the hook head 5211, and the other end of the first connecting portion 5212 is connected to the fixing base 522. Among them, the first connecting portion 5212 and the hook head 5211 are configured as a hook shaped structure, and at least part of the first connecting portion 5212 can be configured to be supported on the supporting member 51. In this case, it is convenient to connect the supporting member 51 and the first connecting portion 5212 of the hanging member 52 into one body by using the second locking member 54.

[0090] Meanwhile, the second connecting portion 5213 can be disposed on the upper side of the first connecting portion 5212 in the height direction. Such a design not only does not affect the hanging of the hanging member 52 on the supporting member 51, but also facilitates connecting the supporting member 51 and the second connecting portion 5213 of the hanging member 52 into one body by using the first locking member 53.

[0091] In some embodiments, as Figure 4 shown, the supporting member 51 includes: a bottom plate 511 and at least one side plate 512. The bottom plate 511 is connected to the sliding member 42, and a hanging hole 5101 is provided on the bottom plate 511; at least one side plate 512 is respectively connected to the bottom plate 511 and the sliding member 42.

[0092] Specifically, in the case where the hook 521 includes a hook head 5211, a first connecting portion 5212, and a second connecting portion 5213, the hook head 5211 passes through the hanging hole 5101 on the bottom plate 511. The bottom plate 511 of the supporting member 51 is connected to the first connecting portion 5212 of the hanging member 52 into one body through the second locking member 54, and the side plate 512 is connected to the second connecting portion 5213 of the hanging member 52 into one body through the first locking member 53.

[0093] Meanwhile, since the bottom plate 511 is connected to the sliding member 42 through the side plate 512, the side plate 512 functions as a reinforcing rib, which can enhance the bonding strength between the bottom plate 511 and the sliding member 42, and ensure that the hanging member 52 is better supported based on the bottom plate 511.

[0094] Among them, the bottom plate 511 can be set to extend in the width direction, and two side plates 512 can be provided. The two side plates 512 are disposed at both ends of the bottom plate 511 in the width direction.

[0095] In some embodiments, as Figure 2 and Figure 3 shown, the first locking member 53 includes a first locking bolt, and the supporting member 51 is provided with a first adjusting hole 5102; the nut of the first locking bolt is limited to one side of the supporting member 51, and the screw rod of the first locking bolt is movably inserted through the first adjusting hole 5102 in the height direction and is threadedly connected to the hanging member 52.

[0096] It can be understood that the first adjusting hole 5102 can be an oblong hole and is configured to extend in the height direction of the cabinet door 1; a first threaded hole 5201 is provided on the hanging member 52. Among them, the first adjusting hole 5102 is provided on the side plate 512 of the supporting member 51, and the first threaded hole 5201 is provided on the second connecting portion 5213 of the hanging member 52.

[0097] In practical applications, the screw rod of the first locking bolt can be passed through the first adjustment hole 5102 in the direction from left to right, and then preliminarily connected to the first threaded hole 5201 on the hanging member 52. After the installation position of the hanging member 52 relative to the supporting member 51 in the height direction is adjusted, the first locking bolt is then screwed until the first locking bolt locks the hanging member 52 and the supporting member 51 together to prevent the hanging member 52 from moving relative to the supporting member 51.

[0098] In some embodiments, such as Figure 2 and Figure 3 shown, the second locking member 54 includes a second locking bolt, and the supporting member 51 is provided with a second adjustment hole 5103; the nut of the second locking bolt is limited to one side of the supporting member 51, and the screw rod of the second locking bolt is movably passed through the second adjustment hole 5103 in the width direction and is threadedly connected to the hanging member 52.

[0099] It can be understood that the second adjustment hole 5103 can be an oval hole and is configured to extend along the width direction of the cabinet door 1; a second threaded hole 5202 is provided on the hanging member 52. Among them, the second adjustment hole 5103 is provided on the bottom plate 511 of the supporting member 51, and the second threaded hole 5202 is provided on the first connecting portion 5212 of the hanging member 52.

[0100] In practical applications, the screw rod of the second locking bolt can be passed through the second adjustment hole 5103 in the direction from bottom to top, and then preliminarily connected to the second threaded hole 5202 on the hanging member 52. After the installation position of the hanging member 52 relative to the supporting member 51 in the width direction is adjusted, the second locking bolt is then screwed until the second locking bolt locks the hanging member 52 and the supporting member 51 together to prevent the hanging member 52 from moving relative to the supporting member 51.

[0101] In some embodiments, such as Figure 2 and Figure 3 shown, the door body assembly further includes: a third locking member 401, and the slide rail 41 is connected to the cabinet door 1 through the third locking member 401; wherein, the third locking member 401 is used to limit the installation position of the slide rail 41 relative to the cabinet door 1 along the thickness direction of the cabinet door 1.

[0102] It can be understood that the slide rail 41 is adjustably arranged on the cabinet door 1 along the thickness direction of the cabinet door 1. After the installation position of the slide rail 41 relative to the cabinet door 1 is adjusted, the third locking member 401 can be used to connect the slide rail 41 and the cabinet door 1 to prevent the slide rail 41 from moving relative to the cabinet door 1 along the thickness direction of the cabinet door 1, so as to realize the adjustment of the installation position of the cabinet door 2 relative to the cabinet door 1 along the thickness direction.

[0103] Optionally, the third locking member 401 can be a locking bolt and is configured to extend in the thickness direction. The locking bolt passes through the mounting hole on the slide rail 41 and is threadedly connected to the cabinet door 1. In practical applications, by adjusting the locking depth of the locking bolt relative to the threaded hole on the cabinet door 1, the mounting position of the slide rail 41 relative to the cabinet door 1 can be adjusted in the thickness direction.

[0104] In some embodiments, to ensure that the slide rail 41 is reliably mounted on the cabinet door 1 and facilitate the adjustment of the mounting positions at both ends of the slide rail 41, there are multiple third locking members 401. A part of the multiple third locking members 401 is disposed between one end of the slide rail 41 and the cabinet door 1, and another part of the multiple third locking members 401 is disposed between the other end of the slide rail 41 and the cabinet door 1.

[0105] Optionally, the third locking member 401 can be a locking bolt and is configured to extend in the height direction of the cabinet door 1; the slide rail 41 is provided with mounting ears, and the mounting ears have mounting holes extending in the thickness direction; the locking bolt passes through the mounting holes on the mounting ears and is threadedly connected to the cabinet door 1. Wherein, the slide rail 41 can be configured to be adjustably disposed in the groove 101 on the cabinet door 1 in the thickness direction, the mounting ears are exposed out of the notch of the groove 101 and are connected to the top surface of the cabinet door 1.

[0106] In practical applications, the locking bolt can be passed through the mounting hole in the direction from top to bottom and connected to the threaded blind hole on the cabinet door 1; after the mounting position of the slide rail 41 relative to the cabinet door 1 is adjusted in the thickness direction, the locking bolt can be screwed to fasten the slide rail 41 on the cabinet door 1.

[0107] In some embodiments, as Figure 3 shown, the sliding member 42 includes a ball bracket 421 and an adapter seat 422; the ball bracket 421 is movably disposed on the slide rail 41 in the width direction, the adapter seat 422 is connected to the ball bracket 421, the supporting member 51 is connected to the adapter seat 422, and the hanging member 52 is connected to the cabinet door 2.

[0108] 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 and there will be no abnormal noise during the movement.

[0109] 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 supporting member 51 can be provided as an integral structure, so that in practical applications, the installation of the supporting member 51 is not required, and it is convenient to support the cabinet door 2 through the supporting member 51.

[0110] Further, along the extending direction of the sliding rail 41, the extending length of the ball bracket 421 can be set to be greater than that of the adapter base 422. This design can increase the contact area between the ball bracket 421 and the sliding rail 41, reduce the contact friction between the ball bracket 421 and the sliding rail 41, and thus ensure the stability and reliability of the movement of the sliding member 42 relative to the sliding rail 41.

[0111] In some embodiments, as Figure 9 shown, the door body assembly further includes: a sliding door mechanism 6, which is configured to be disposed on the cabinet body 3 and is in transmission connection with the cabinet door 2, and is used to drive the cabinet door 2 to move relative to the box door 1 in the width direction during the opening and closing process of the box door 1; the refrigeration device is configured to be disposed 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 can avoid the first cabinet body 7 or the second cabinet body 8.

[0112] It can be understood 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. This design enables the cabinet body 3 of the refrigeration device to be integrally embedded in the accommodation space. During the process of the box door 1 passing through the opening to control the opening or closing of the accommodation space, the sliding door mechanism 6 is configured to drive the cabinet door 2 to move in the width direction away from or towards the hinge 9. This design can ensure that the cabinet door 2 avoids the side walls of the first cabinet body 7 and the second cabinet body 8, prevent the side edges of 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 box door 1 can be opened and closed smoothly.

[0113] 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 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 box door 1 to be fully opened, which is convenient for users to access items.

[0114] 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 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.

[0115] In this embodiment, the cabinet door 2 is movably arranged outside the door 1 of the box along the width direction of the door 1 of the box, and the sliding door mechanism 6 is used to drive the cabinet door 2 to move relative to the door 1 of the box during the opening or closing of the door 1 of the box, so that the door 1 of the box can avoid the first cabinet body 7 and the second cabinet body 8 on the side during the opening and closing processes, avoiding the interference between the cabinet door 2 and the outside when the door 1 of the box rotates, and 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 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.

[0116] In some embodiments, the sliding door mechanism 6 is connected to the sliding member 42 to drive the sliding member 42 to move along the slide rail 41.

[0117] It can be understood that during the opening and closing of the door 1 of the box, the sliding door mechanism 6 drives the sliding member 42 to move relative to the slide rail 41 along 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 door 1 of the box, ensuring that the cabinet door 2 does not touch the cabinet body on the side. This design realizes the integration of the sliding door mechanism 6 and the sliding module 4.

[0118] 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.

[0119] In some embodiments, as Figure 8 and Figure 9 shown, the door 1 of the box is rotatably connected to the box body 3 of the refrigeration equipment through the hinge 9, and the cabinet door 2 can move between a first position and a second position relative to the door 1 of the box along the width direction; when the cabinet door 2 is in the first position, the door 1 of the box closes the storage compartment, and the side of the cabinet door 2 facing the hinge 9 approaches the hinge 9; when the cabinet door 2 is in the second position, the door 1 of the box opens the storage compartment, and the side of the cabinet door 2 facing the hinge 9 moves away from the hinge 9. At this time, the side of the cabinet door 2 and the side of the door 1 of the box are misaligned to avoid the side wall of the first cabinet body 7 or the second cabinet body 8.

[0120] It can be understood that the storage compartment is used to store items to be refrigerated or frozen. When the door 1 of the box closes the storage compartment, the door 1 of the box is in the closed state, and the side of the cabinet door 2 is at a first distance (close to zero) relative to the hinge 9 of the refrigeration equipment. For example, the side of the cabinet door 2 and the side of the door 1 of the box are flush. At this time, the cabinet door 2 can completely block the door 1 of the box, ensuring that the cabinet door 2 of the accommodation space exposed by the refrigeration equipment is consistent with the surrounding first cabinet body 7 and the second cabinet body 8 in appearance.

[0121] When the door 1 of the box is opened to access the storage compartment, the door 1 of the box is in the open state. The side of the cabinet door 2 is at a second distance (the second distance is greater than the first distance) relative to the hinge 9 of the refrigeration device. For example, the side of the cabinet door 2 and the side of the door 1 of the box are offset, and a gap is formed that can accommodate the side of the first cabinet body 7 or the second cabinet body 8, so as to prevent the cabinet door 2 from colliding with or interfering with the first cabinet body 7 or the second cabinet body 8 due to the opening of the door 1 of the box.

[0122] In some embodiments, as Figure 9 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 door 1 of the box; the linear drive is arranged between the door 1 of the box 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 door 1 of the box according to the opening and closing signal fed back by the trigger.

[0123] 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 and the linear drive are electrically connected.

[0124] The trigger can be a photoelectric switch, which judges the opening and closing state of the door 1 of the box by detecting the change in the distance between the door 1 of the box and the box body 3. The trigger can also be an angle sensor, which judges the opening and closing state of the door 1 of the box by detecting the change in the angle between the door 1 of the box and the box body 3;

[0125] The linear drive can be a telescopic rod such as a cylinder or an electric push rod. The linear drive extends along the width direction. The first end of the linear drive is connected to the door 1 of the box, and the second end of the linear drive is connected to the cabinet door 2, so as to drive the cabinet door 2 to move relative to the door 1 of the box along the width direction.

[0126] Wherein, in the case where the door body assembly includes the above-mentioned sliding module 4 and the hanging structure 5, the linear drive is arranged on the door 1 of the box. The first end of the linear drive is connected to the door 1 of the box, and the second end of the linear drive is connected to the sliding member 42 of the sliding module 4.

[0127] Taking the trigger as an angle sensor as an example, the control of the linear drive on the cabinet door 2 during the opening and closing process of the door 1 of the box will be specifically described as follows.

[0128] In practical applications, the angle sensor is installed on the hinge axis corresponding to the hinge 9 to monitor the rotation state of the door 1 of the box relative to the hinge axis. When the door 1 of the box is opened, the angle sensor feeds back an opening signal to the linear drive, and the linear drive drives the cabinet door 2 to move along the width direction of the door 1 of the box away from the hinge 9; when the door 1 of the box is closed, the angle sensor feeds back a closing signal to the linear drive, and the linear drive drives the cabinet door 2 to move along the width direction of the door 1 of the box towards the hinge 9.

[0129] Further, as the opening or closing amplitude of the box door 1 varies, the angle sensor can also obtain the rotation angle of the box door 1, and the linear drive member can determine the preset value of the movement according to the rotation angle. During the opening process of the box door 1, according to the rotation angle when the box 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 box door 1, according to the rotation angle when the box 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.

[0130] In some embodiments, to ensure the stability and reliability of the movement of the cabinet door 2 relative to the box door 1, multiple sets of sliding modules 4 and hanging structures 5 are respectively provided and arranged in a one-to-one correspondence. At least one set of sliding modules 4 is provided between the upper end of the box door 1 and the upper end of the cabinet door 2, and at least one set of sliding modules 4 is provided between the lower end of the box door 1 and the lower end of the cabinet door 2.

[0131] Specifically, four sets of sliding modules 4 are provided. Two of the sliding modules 4 are arranged along the width direction of the box door 1 and are provided 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 provided between the lower end of the box door 1 and the lower end of the cabinet door 2.

[0132] In some embodiments, as Figure 7 shown, the box door 1 is provided with a groove 101, and the sliding module 4 is arranged in the groove 101; the door body assembly further includes a decorative member, and the decorative member cover is used to cover the notch end of the groove 101.

[0133] 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, and at this time, there is no decorative member at the notch end of the groove 101.

[0134] 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.

[0135] In a second aspect, as Figure 7 、 Figure 8 and Figure 9 shown, an 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 box door 1 is rotatably arranged on the box body 3 to open or close the storage compartment.

[0136] It is understandable that multiple storage compartments can be provided in the cabinet 3, and the multiple storage compartments 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 assemblies for controlling the opening and closing states of each storage compartment. Among them, hinges 9 are provided on one side of the cabinet 3 corresponding to each storage compartment, and the cabinet 3 can be rotatably connected to the cabinet door 1 of the door assembly corresponding to the storage compartment through the hinges 9.

[0137] For each set of door assemblies, since the cabinet door 2 can move left and right relative to the cabinet door 1 in the width direction, when the refrigeration device is fully embedded, during the process of opening the cabinet door 1, the cabinet door 2 can be controlled to move away from the hinge 9 relative to the cabinet door 1 to avoid the cabinet body around the refrigeration device; during the process of closing the cabinet door 1, the cabinet door 2 can be controlled to move towards the side close to the hinge 9 relative to the cabinet door 1 until the cabinet door 2 returns to its original position, ensuring that the side edges of the cabinet door 1 and the cabinet door 2 are flush.

[0138] Since the refrigeration device includes door assemblies, and the specific structure of the door assemblies refers to the above embodiments, the refrigeration device 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.

[0139] 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 any combination, modification or equivalent replacement of the technical solutions of the present invention does 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.
