[0065] The following is combined with Figures 1 to 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.

[0066] In the first aspect, Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the utility model provides a door body assembly, which is applied to refrigeration equipment, including: a box door 1, a cabinet door 2 and a hanging structure 3.

[0067] The cabinet door 1 is configured to be rotatably disposed on a cabinet body 6 of the refrigeration device, and the cabinet door 2 is disposed on a side of the cabinet door 1 facing away from the cabinet body 6 .

[0068] The hanging structure 3 includes a mounting frame 31, a guide frame 32 and a pulley block 33; the mounting frame 31 and the guide frame 32 are respectively arranged on the box door 1 and the cabinet door 2; the pulley block 33 includes at least two pulleys 331, at least two pulleys 331 are arranged along the width direction of the box door 1, and are movably arranged on the guide frame 32.

[0069] The pulley 331 can be adjustably arranged on the mounting frame 31 along the height direction and the thickness direction of the cabinet door 2 .

[0070] Among them, the thickness of the cabinet door 1 is 18-60mm, for example, the thickness of the cabinet door 1 can be 18mm, 25mm, 35mm, 50mm, 55mm or 60mm; the thickness of the cabinet door 2 is 12-26mm, for example, the thickness of the cabinet door 2 can be 12mm, 15mm, 20mm or 26mm; the cabinet door 2 can be a wooden door panel or a plastic door panel.

[0071] It is understandable that the box body 6 of this embodiment is equipped with a hinge 7, and the hinge 7 is provided with a hinge shaft, and the box door 1 is rotatably arranged on the hinge shaft to realize the opening or closing of the box door 1 relative to the box body 6. The outer side of the box door 1 is provided with a cabinet door 2 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 environment.

[0072] Based on the movement of the pulley 331 along the width direction of the guide frame 32, the guide frame 32 is used to slide on the mounting frame 31 along the width direction, thereby realizing the movement of the cabinet door 2 on the box door 1 along the width direction.

[0073] The position of the pulley 331 on the mounting frame 31 can be adjusted along the height direction and thickness direction of the cabinet door 2. After the cabinet door 2 is installed on the box door 1, the position of the pulley 331 on the mounting frame 31 can be adjusted to achieve fine-tuning of the position of the cabinet door 2 relative to the box door 1, thereby ensuring the installation position accuracy of the cabinet door 2.

[0074] Specifically, the position of the pulley 331 on the mounting bracket 31 can be adjusted by a slide rail slider, a telescopic rod, or a threaded connection.

[0075] For the door body assembly shown in the present embodiment, a hanging structure 3 is provided between the box door 1 and the cabinet door 2, and a mounting frame 31, a guide frame 32 and a pulley block 33 are provided on the hanging structure 3; the mounting frame 31 is provided on the box door 1, and the guide frame 32 is provided on the cabinet door 2; the pulley 331 in the pulley block 33 is slidably matched with the guide frame 32 along the width direction; and the pulley 331 can be adjusted along the height direction and the thickness direction of the cabinet door 2 and is provided on the mounting frame 31, thereby realizing the adjustment of the position of the cabinet door 2 relative to the box door 1 in the height direction, the width direction and the thickness direction, so that the pulley 331 can be used to facilitate the adjustment of the position of the cabinet door 2 relative to the box door 1, thereby improving the installation efficiency of the cabinet door 2 and ensuring the aesthetic quality of the installation of the cabinet door 2.

[0076] In some embodiments, Figure 2 As shown, the pulley 331 and the mounting frame 31 are connected via an adjusting component 4 , and the adjusting component 4 includes: a driving component 41 and a connecting component 42 .

[0077] The driving member 41 is disposed on the mounting frame 31 .

[0078] The adapter 42 is movably disposed on the mounting frame 31 along the height direction. The driving member 41 is connected to the adapter 42 to drive the adapter 42 to move along the height direction. The pulley 331 is adjustably disposed on the adapter 42 along the thickness direction.

[0079] It can be understood that under the action of the driving force of the driving member 41, the adapter 42 moves along the height direction to drive the pulley 331 to move along the height direction, and then drive the guide frame 32 to move along the height direction relative to the mounting frame 31. At the same time, the pulley 331 can move along the thickness direction on the adapter 42, so that the guide frame 32 can move along the thickness direction relative to the mounting frame 31, thereby realizing the movement of the guide member relative to the mounting frame 31 in the height direction and the thickness direction, and then realizing the movement of the cabinet door 2 relative to the box door 1 in the height direction and the thickness direction.

[0080] Optionally, the driving member 41 may be a telescopic rod or a linear motor, and the movement of the adapter 42 relative to the mounting frame 31 along the height direction may be achieved through the structure of a guide rail slider or through a lead screw connecting rod mechanism.

[0081] In some embodiments, Figure 2 and Figure 4 As shown, the driving member 41 includes a first adjusting bolt 411 .

[0082] The first adjusting bolt 411 is arranged to extend in the height direction. The first adjusting bolt 411 is rotatably arranged on the mounting bracket 31 and is threadedly connected to the adapter 42.

[0083] A guiding groove 311 is provided on the mounting bracket 31. The adapter 42 is movably arranged in the guiding groove 311 in the height direction. The first adjusting bolt 411 is used to receive torque drive, and thus control the adapter 42 to move along the guiding groove 311.

[0084] It can be understood that a threaded hole is provided at the position where the adapter 42 is connected to the first adjusting bolt 411. The threaded hole is threadedly connected to the first adjusting bolt 411. By screwing the first adjusting bolt 411, the change in the depth of the first adjusting bolt 411 extending into the adapter 42 is used to realize the drive of the adapter 42 in the height direction. The threaded connection not only firmly connects the first adjusting bolt 411 and the adapter 42, but also accurately realizes the adjustment of the mounting position of the adapter 42 in the height direction.

[0085] Under the guiding and limiting effects of the guiding groove 311, the adapter 42 moves relative to the guiding groove 311 in the height direction, ensuring the stability and reliability of the movement of the adapter 42 in the height direction. Specifically, in this embodiment, two parallel strip-shaped plates are arranged on the guiding frame 32. The two strip-shaped plates extend in the height direction and are both perpendicularly arranged to the guiding frame 32. The spaced space between the two strip-shaped plates forms the guiding groove 311. The guiding groove 311 is arranged opposite to the first adjusting bolt 411. By the torque drive of the first adjusting bolt 411, the adapter 42 is driven to move in the guiding groove 311 in the height direction, and the adjusting structure is easy to operate and convenient to operate.

[0086] In some embodiments, as Figure 2 and Figure 5 shown, the adapter 42 includes: a first connecting portion 421 and a second connecting portion 422.

[0087] The first connecting portion 421 is threadedly connected to the first adjusting bolt 411.

[0088] The second connecting portion 422 is connected to the first connecting portion 421 and is movably arranged in the guiding groove 311 in the height direction. The pulley 331 is adjustably arranged on the second connecting portion 422 in the thickness direction.

[0089] It can be understood that the first adapter portion and the second connection portion 422 of the present embodiment are both strip plates, the first connection portion 421 and the second connection portion 422 are vertically arranged, the first connection portion 421 is threadedly connected to the first adjusting bolt 411, and after the first adjusting bolt 411 receives the torque drive, the first connection portion 421 drives the second connection portion 422 to move in the height direction in the guide groove 311 to adjust the relative height between the pulley 331 and the mounting frame 31, and the relative position of the pulley 331 and the second connection portion 422 along the thickness direction can also be adjusted to adjust the distance between the pulley 331 and the mounting frame 31 in the thickness direction, thereby realizing the movement of the cabinet door 2 relative to the box door 1 in the height direction and the thickness direction.

[0090] In some embodiments, Figure 2 and Figure 6 As shown, the pulley 331 includes: a wheel body 3311 and a central axis 3312 , and the wheel body 3311 is rotatably disposed on the central axis 3312 .

[0091] The mounting frame 31 is provided with a first strip hole 312 extending in the height direction; the wheel body 3311 is located on the side of the mounting frame 31 facing the guide frame 32 and is provided on the guide frame 32; the adapter 42 is provided on the side of the mounting frame 31 away from the guide frame 32.

[0092] The central axis 3312 passes through the first strip hole 312 and is adjustably disposed on the adapter 42 along the thickness direction.

[0093] It can be understood that since the wheel body 3311 is arranged on the side of the mounting frame 31 facing the guide frame 32, and the adapter 42 is on the side of the mounting frame 31 away from the guide frame 32, the wheel body 3311 and the adapter 42 are respectively arranged on both sides of the mounting frame 31, and when the driving member 41 drives the adapter 42 to move along the height direction, the wheel body 3311 is connected to the adapter 42 through the central axis 3312, and the central axis 3312 can move in the height direction along the first strip hole 312 to achieve the relative height of the wheel body 3311 and the mounting frame 31, and the distance between the central axis 3312 and the adapter 42 in the thickness direction can also be adjusted to achieve the adjustment of the thickness direction of the wheel body 3311 and the mounting frame 31, thereby realizing the movement of the cabinet door 2 relative to the box door 1 in the height direction and the thickness direction.

[0094] In some embodiments, Figure 2 and Figure 6 As shown, one end of the central shaft 3312 away from the wheel body 3311 is configured as a threaded shaft, and is threadedly connected to the adapter 42 based on the threaded shaft.

[0095] The central shaft 3312 is used to receive torque drive, thereby achieving movement relative to the adapter 42 along the thickness direction.

[0096] It is understandable that in this embodiment, a threaded hole is provided on the side of the adapter 42 close to the mounting frame 31, and the threaded shaft of the central axis 3312 is threadedly connected to the threaded hole to achieve a firm connection between the central axis 3312 and the adapter 42, and the central axis 3312 and the adapter 42 are easy to install and disassemble.

[0097] When the center shaft 3312 is screwed, the depth of the threaded shaft extending into the adapter 42 changes to drive the adapter 42 in the thickness direction. The threaded connection not only firmly connects the threaded shaft and the adapter 42, but also accurately adjusts the installation position of the adapter 42 in the thickness direction.

[0098] In some embodiments, Figure 2 As shown, the mounting frame 31 is adjustably arranged on the cabinet door 1 along the width direction, and the guide frame 32 is arranged on the cabinet door 2.

[0099] It is understandable that the mounting frame 31 can be adjusted relative to the box door 1 along the width direction. Based on the connection between the mounting frame 31 and the guide frame 32 by the pulley group 33, the guide frame 32 can also be adjusted relative to the box door 1 along the width direction, thereby driving the adjustment of the cabinet door 2 relative to the box door 1 along the width direction. When the cabinet door 2 is installed on the box door 1, the mounting frame 31 can be fine-tuned relative to the box door 1 in the width direction to achieve precise adjustment of the cabinet door 2 on the box door 1 along the width direction.

[0100] Specifically, the adjustment of the mounting frame 31 relative to the width direction of the door 1 can be achieved through a telescopic rod, or through a slide rail and slider structure.

[0101] In some embodiments, Figure 2 As shown, the mounting bracket 31 and the door 1 are connected via a second adjusting bolt 412 .

[0102] The mounting frame 31 is provided with a second strip hole 313 , which extends along the width direction. The second adjusting bolt 412 is passed through the second strip hole 313 and is threadedly connected to the door 1 .

[0103] It is understandable that since the second strip hole 313 is extended along the width direction, the second adjusting bolt 412 can move along the width direction in the second strip hole 313. Based on the threaded connection between the second adjusting bolt 412 and the box door 1, the movement between the box door 1 and the mounting frame 31 along the width direction is achieved. The structure is simple and easy to operate, and precise adjustment of small displacements can be achieved.

[0104] In some embodiments, Figure 7 As shown, the guide frame 32 includes: a first track segment 321 , a second track segment 322 and a connecting segment 323 .

[0105] The first track segment 321 and the second track segment 322 are spaced apart in the height direction, and both the first track segment 321 and the second track segment 322 extend in the width direction.

[0106] The connecting section 323 is disposed between the first end of the first track section 321 and the first end of the second track section 322 ; the pulley 331 is movably disposed between the first track section 321 and the second track section 322 .

[0107] It is understandable that the first track segment 321 and the second track segment 322 of the present embodiment are respectively arranged perpendicular to the connecting segment 323, and threaded holes are provided on the first track segment 321, the second track segment 322 and the connecting segment 323, and the first track segment 321, the second track segment 322 and the connecting segment 323 are fixed to the cabinet door 2 by fasteners.

[0108] The pulley 331 can move between the first track section 321 and the second track section 322 to achieve the movement of the guide frame 32 relative to the mounting frame 31 along the width direction, thereby driving the cabinet door 2 to move relative to the box door 1 along the width direction.

[0109] In some embodiments, Figure 2 and Figure 3 As shown, the guide frame 32 further includes a limiting member 324 .

[0110] The limiting member 324 is detachably disposed between the second end of the first track segment 321 and the second end of the second track segment 322 .

[0111] It is understandable that a gap is formed between the first track segment 321, the second track segment 322 and the connecting segment 323, and the limit member 324 is used to confine the pulley 331 in the gap. After the pulley 331 is installed in the gap, the limit member 324 is inserted into the open end of the gap to block the open end, so that when the pulley 331 slides to the open end of the gap, the limit member 324 can limit the sliding, so as to prevent the pulley 331 from detaching from the gap at the open end, causing the pulley 331 to separate from the guide frame 32, thereby ensuring the sliding reliability of the pulley 331.

[0112] In some examples, the first rail segment 321 is provided with a socket, and the second rail segment 322 is provided with a limit groove. The socket and the limit groove are arranged relative to each other, and the limit member 324 is passed through the socket. One end of the limit member 324 is inserted into the limit groove. The socket is used to guide the limit member 324 into the limit groove, and the limit member 324 is fixed to the guide frame 32 by the socket and the limit groove, ensuring that the guide frame 32 will not be separated from the limit member 324.

[0113] In some embodiments, Figure 8As shown in the figure, the door body assembly further includes: a sliding door mechanism 5, which is configured to be disposed on the cabinet body 6 or the cabinet door 1 and is in transmission connection with the cabinet door 2. The sliding door mechanism 5 is used to drive the cabinet door 2 to move relative to the cabinet door 1 in the width direction during the opening and closing process of the cabinet door 1.

[0114] The refrigeration device is configured to be disposed in the accommodation space between the first cabinet body 8 and the second cabinet body; during the opening or closing process of the cabinet door 1, the sliding door mechanism 5 is used to change the position of the cabinet door 2 on the cabinet door 1 so that the cabinet door 2 avoids the first cabinet body 8 or the second cabinet body.

[0115] It can be understood that there is an opening on the outer side of the accommodation space between the first cabinet body 8 and the second cabinet body. This design enables the refrigeration device to be integrally embedded in the cabinet body. During the process of the cabinet door 1 passing through the opening to control the opening or closing of the accommodation space, the sliding door mechanism 5 is configured to drive the cabinet door 2 to move a preset distance in the cabinet door 1 in a direction away from or close to the cabinet body 6 so that the cabinet door 2 avoids the first cabinet body 8 and the second cabinet body.

[0116] During the process of the cabinet door 1 passing through the opening to control the opening or closing of the accommodation space, the sliding door mechanism 5 is configured to drive the cabinet door 2 to move in the cabinet door 1 in a direction away from or close to the cabinet body 6, and can also control the cabinet door 2 to move a preset distance. This design is mainly to avoid interference between the cabinet door 2 and the side walls of the first cabinet body 8 and the second cabinet body. Through the movement of the preset distance, the cabinet door 1 can be smoothly opened or closed without colliding or jamming with the side walls of the cabinet body. 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 beauty and sealing.

[0117] In some embodiments, as Figure 8 shown, the cabinet door 1 is rotatably connected to the cabinet body 6 through a hinge 7; the cabinet door 2 can move between a first position and a second position relative to the cabinet door 1 in the width direction.

[0118] When the cabinet door 2 is in the first position, the cabinet door 1 closes the storage compartment, and the side of the cabinet door 2 facing the hinge 7 is disposed close to the hinge 7.

[0119] When the cabinet door 2 is in the second position, the cabinet door 1 opens the storage compartment, and the side of the cabinet door 2 facing the hinge 7 is disposed away from the hinge 7 to avoid the first cabinet body 8 or the second cabinet body.

[0120] It is understandable that the interior of the storage room is used to store items to be refrigerated or frozen. When the door 1 of the cabinet closes the storage room, 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 7 of the refrigeration device. 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 door body of the accommodation space exposed by the refrigeration device is consistent with the surrounding first cabinet 8 and second cabinet in appearance.

[0121] When the door 1 of the cabinet opens the storage room, 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 7 of the refrigeration device. For example, the side wall of the cabinet door 2 and the side wall of the door 1 of the cabinet are misaligned, and a gap is formed that can accommodate the side of the first cabinet 8 or the second cabinet, so as to avoid collision or interference between the cabinet door 2 and the first cabinet 8 or the second cabinet due to the opening of the door 1 of the cabinet.

[0122] In some embodiments, as Figure 8 shown, the sliding door mechanism 5 includes: a trigger and a linear driving member 41.

[0123] The trigger is used to obtain the opening and closing signal of the door 1 of the cabinet.

[0124] The linear driving member 41 is arranged between the door 1 of the cabinet and the cabinet door 2 and is connected to the trigger.

[0125] Among them, the linear driving member 41 is used to drive the cabinet door 2 to move along the width direction of the door 1 of the cabinet according to the opening and closing signal fed back by the trigger.

[0126] It is understandable that the linear driving member 41 is installed on the door 1 of the cabinet, and the output end of the linear driving member 41 is connected to the cabinet door 2. The trigger is electrically connected to the linear driving member 41, or the trigger is wirelessly communicatively connected to the linear driving member 41.

[0127] This embodiment further includes a controller. The trigger is electrically connected to the controller, and the controller is electrically connected to the linear driving member 41. The controller is used to receive the opening and closing signal of the door 1 of the cabinet fed back by the trigger and control the linear driving member 41 to drive the movement of the cabinet door 2.

[0128] Specifically, the trigger can be a photoelectric switch, which judges the opening and closing state of the door 1 of the cabinet by detecting the relative distance between the door 1 of the cabinet and the cabinet body 6. The trigger can also be an angle sensor, which judges the opening and closing state of the door 1 of the cabinet by detecting the relative angle between the door 1 of the cabinet and the cabinet body 6; the linear driving member 41 can be a cylinder, a hydraulic cylinder, or an electric push rod.

[0129] In practical applications, during the opening process of the cabinet door 1, the linear drive member 41 drives the cabinet door 2 to move away from the hinge 7 in the width direction of the cabinet door 1, that is, to move leftward relative to the cabinet door 1, so as to avoid interference between the cabinet door 2 and the cabinet body around the refrigeration equipment; during the closing process of the cabinet door 1, the linear drive member 41 drives the cabinet door 2 to move closer to the hinge 7 in the width direction of the cabinet door 1, that is, to move rightward relative to the cabinet door 1, so as to ensure that the cabinet door 2 can avoid the cabinet body around the refrigeration equipment when the cabinet door 1 is closed and reset the cabinet door 2.

[0130] For the sliding door mechanism 5 shown in this embodiment, by using a trigger member to obtain the opening and closing signal of the cabinet door 1, and arranging a linear drive member 41 between the cabinet door 1 and the cabinet door 2. When the cabinet door 1 is opened, the linear drive member 41 drives the cabinet door 2 to move away from the hinge 7 in the width direction of the cabinet door 1, so that the cabinet door 2 does not interfere with the cabinet body on the side. When the cabinet door 1 is closed, the linear drive member 41 drives the cabinet door 2 to move closer to the hinge 7 in the width direction of the cabinet door 1, so that the cabinet door 2 returns to its original position, ensuring that the cabinet door 2 does not interfere with the cabinet body around the refrigeration equipment.

[0131] In some embodiments, as Figure 8 shown, the trigger member includes a displacement sensor, and the displacement sensor is used to detect the rotation direction of the cabinet door 1 to obtain the opening and closing signal.

[0132] It can be understood that the displacement sensor can be an angular displacement sensor. The angular displacement sensor of this embodiment is installed on the hinge axis of the hinge 7, and the angular displacement sensor can detect the rotation direction and rotation angle of the cabinet door 1 around the hinge axis.

[0133] The displacement sensor can detect the rotation direction of the cabinet door 1 relative to the cabinet body 6 when the cabinet door 1 rotates. According to the opening and closing state of the cabinet door 1, the opening and closing signal is divided into an opening signal and a closing signal; when the cabinet door 1 is opened, the displacement sensor feeds back the opening signal to the linear drive member 41, and the linear drive member 41 drives the cabinet door 2 to move away from the hinge 7 in the width direction of the cabinet door 1; correspondingly, when the cabinet door 1 is closed, the displacement sensor feeds back the closing signal to the linear drive member 41, and the linear drive member 41 drives the cabinet door 2 to move closer to the hinge 7 in the width direction of the cabinet door 1.

[0134] Further, as the opening or closing amplitude of the cabinet door 1 varies, the displacement sensor can also obtain the rotation angle of the cabinet door 1. The linear drive member 41 can determine the preset value of the movement according to the rotation angle. When the cabinet door 1 is in the open state, according to the rotation angle when the cabinet door 1 is opened, the stroke of the telescopic end of the linear drive member 41 is determined, and then the linear drive member 41 drives the cabinet door 2 to move a preset distance away from the hinge 7 to avoid interference with the external cabinet body; correspondingly, when the cabinet door 1 is in the closed state, according to the rotation angle when the cabinet door 1 is closed, the stroke of the telescopic end of the linear drive member 41 is determined, and then the linear drive member 41 drives the cabinet door 2 to move a preset distance toward the hinge 7 to avoid interference between the cabinet door 2 and the external cabinet body, and finally, the cabinet door 2 is reset.

[0135] In this embodiment, by setting the trigger member as a displacement sensor, the opening and closing signal and the rotation angle of the cabinet door 1 are synchronously obtained, and then the preset value of the movement of the cabinet door 2 along the width direction of the cabinet door 1 is accurately determined, so that the movement of the cabinet door 2 relative to the cabinet door 1 can be consistent with the rotation amplitude of the cabinet door 1, avoiding interference and ensuring the beauty and reliability of the movement process of the cabinet door 2 relative to the cabinet door 1.

[0136] In some embodiments, as Figure 8 shown, the trigger member includes a push-button switch, and the push-button switch is used to receive the pressing input of the corresponding opening and closing signal; the push-button switch is configured to be connected to the opening mechanism that drives the cabinet door 1 to open and close.

[0137] It can be understood that the opening mechanism in this embodiment is used to open or close the cabinet door 1. The push-button switch is connected to the opening mechanism, and when the push-button switch is triggered, it controls the opening mechanism to open or close the cabinet door 1.

[0138] Generally, built-in refrigerators are designed in a style without handles, using a pressure opening system or a hidden notch instead of a traditional handle, or a push-button switch can also be used to control the opening and closing of the cabinet door 1 of the built-in refrigerator. The push-button switch in this embodiment is arranged on the cabinet door 2 of the refrigerator and is used to control the opening and closing of the cabinet door 1 by pressing the button of the push-button switch. At the same time, the push-button switch feeds back the opening and closing signal of the cabinet door 1 to the linear drive member 41, and the linear drive member 41 drives the cabinet door 2 to move along the width direction of the cabinet door 1.

[0139] Specifically, after the push-button switch receives the input instruction for the cabinet door 1 to open, the push-button switch feeds back the opening signal to the opening mechanism and the linear drive member 41. The opening mechanism drives the cabinet door 1 to open. At the same time, the linear drive member 41 drives the cabinet door 2 to move away from the hinge 7 along the width direction of the cabinet door 1 to ensure that the cabinet door 2 does not interfere with the surrounding parts while the cabinet door 1 is opening.

[0140] After the button switch receives the input instruction that the cabinet door 1 is closed, the button switch feeds back the closed signal to the door opening mechanism and the linear driving member 41. The door opening mechanism drives the cabinet door 1 to close. At the same time, the linear driving member 41 drives the cabinet door 2 to move in the width direction of the cabinet door 1 towards the hinge 7, so as to ensure that when the cabinet door 1 is closed, the cabinet door 2 does not interfere with the surrounding parts, and can be reset with the complete closing of the cabinet door 1 to ensure the aesthetics of the cabinet door 2.

[0141] In this embodiment, by setting the trigger member as a button switch, the button switch can not only control the opening and closing of the cabinet door 1 by the door opening mechanism, but also feed back the opening and closing signal of the cabinet door 1 to the linear driving member 41, so that the linear driving member 41 drives the cabinet door 2 to move in the width direction of the cabinet door 1, enabling the cabinet door 2 to open and close synchronously with the cabinet door 1 while avoiding interference with the surrounding cabinet body, ensuring the synchronism and aesthetics of the opening and closing of the cabinet door 1 and the cabinet door 2.

[0142] In some embodiments, the linear driving member 41 includes a linear motor or a telescopic rod.

[0143] It can be understood that as Figure 8 shown, the linear motor is installed on the cabinet door 1, and the output end of the linear motor is connected to the cabinet door 2. The linear motor drives the linear movement of the cabinet door 2 through the linear drive of the cabinet door 2, realizing the movement of the cabinet door 2 in the width direction of the cabinet door 1. The linear motor has a fast reaction speed and high sensitivity, and can quickly respond and accurately adjust the movement distance for the movement adjustment of the cabinet door 2 within a small distance range along the cabinet door 1, realizing the reliability and stability of the movement of the cabinet door 2 relative to the cabinet door 1.

[0144] The fixed end of the telescopic rod is connected to the cabinet door 1, and the telescopic end of the telescopic rod is connected to the cabinet door 2. By the telescopic movement of the telescopic rod, the distance between the rotation center of the cabinet door 2 and the cabinet door 1 is adjusted, thereby realizing the movement of the cabinet door 2 in the width direction of the cabinet door 1. The telescopic rod is flexible to adjust and saves space, and can flexibly adjust the relative movement between the cabinet door 1 and the cabinet door 2 within the limited space between the cabinet door 1 and the cabinet door 2. Moreover, the design of the telescopic rod is simple and can be coordinated with the overall home environment, improving the consistency of the home environment.

[0145] Specifically, the telescopic rod can be an electric push rod or a cylinder.

[0146] In the second aspect, as Figure 8 and Figure 9 shown, the embodiment of the present utility model also provides a refrigeration device, including: a box body 6 and the door body assembly as above. The box body 6 has a storage compartment, and the cabinet door 1 is rotatably arranged on the box body 6 to open or close the storage compartment.

[0147] Specifically, since the refrigeration device includes a door assembly, and the specific structure of the door assembly 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 achieved by all the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0148] It can be understood that the box door 1 is used to open and close the storage compartment. When the refrigeration device is fully embedded, in order to keep the consistency between the refrigeration device and the surrounding cabinet, a cabinet door 2 with the same material and color as the surrounding cabinet is installed on the outer side of the box door 1.

[0149] The refrigeration device of this embodiment can install the cabinet door 2 on the box door 1 through the sliding door mechanism 5. Moreover, during the installation process of the cabinet door 2, the cabinet door 2 can also be adjusted in the height direction, width direction, and thickness direction of the box door 1, improving the installation efficiency of the cabinet door.

[0150] 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.
