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

[0070] Combine the following Figures 1 to 15 , the door body assembly and refrigeration equipment provided by the embodiment of the utility model are described in detail through specific embodiments and their application scenarios.

[0071] In the first aspect, Figure 1 , Figure 2 and Figure 14 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 first hanging structure 3.

[0072] The cabinet door 1 is configured to be rotatably disposed on a cabinet body 8 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 8 .

[0073] The first hanging structure 3 includes a supporting sleeve 31, a locking piece 32 and a connector 33. One of the supporting sleeve 31 and the connector 33 is movably arranged on the door 1 along the width direction of the door 1, and the other of the supporting sleeve 31 and the connector 33 is arranged on the cabinet door 2; the connector 33 is used to be inserted into the supporting sleeve 31.

[0074] The locking member 32 is movably disposed on the supporting sleeve 31 and is used to be connected to the plug-in member 33 .

[0075] It is understandable that the box body 8 of this embodiment is equipped with a hinge 9, and the hinge 9 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 8. 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.

[0076] A first sliding part and a second sliding part are respectively arranged on the cabinet door 2 and the box door 1. The first sliding part and the second sliding part are slidably matched in the width direction. The first sliding part can be installed on the box door 1, and the second sliding part can be installed on the cabinet door 2. And the second sliding part is connected to one of the support sleeve 31 and the plug-in part 33. The relative sliding of the first sliding part and the second sliding part realizes the relative sliding of the box door 1 and the cabinet door 2.

[0077] In this embodiment, the support sleeve 31 can be movably arranged on the box door 1 along the width direction of the box door 1, and the plug-in part 33 is arranged on the cabinet door 2. Or the plug-in part 33 can be movably arranged on the box door 1 along the width direction of the box door 1, and the support sleeve 31 is arranged on the cabinet door 2. Both can realize the installation of the cabinet door 2 relative to the box door 1.

[0078] When installing the cabinet door 2 on the box door 1, the plug-in part 33 is inserted into the support sleeve 31. The locking part 32 can be movably adjusted relative to the support sleeve 31 and is connected to the plug-in part 33 to limit the plug-in part 33 in the support sleeve 31, so as to realize the stable installation of the cabinet door 2 on the box door 1 and prevent it from falling off easily.

[0079] Specifically, the locking part 32 can be a sleeve with a threaded structure, and is connected to the plug-in part through the threaded fit with the support sleeve and the plug-in part. The locking part can also be a spring block installed with an elastic part, and the connection and separation with the plug-in part are realized by pressing the spring block.

[0080] For the door body assembly shown in this embodiment, by providing a first hanging structure 3 between the box door 1 and the cabinet door 2, and setting the box door 1, the cabinet door 2 and the first hanging structure 3 on the first hanging structure 3. When installing the cabinet door 2 on the box door 1, the plug-in part 33 is inserted into the support sleeve 31. Through the movable adjustment of the locking part 32 relative to the support sleeve 31 and the connection with the plug-in part 33, the plug-in part 33 is limited in the support sleeve 31, realizing the firm connection between the plug-in part 33 and the support sleeve 31, and further realizing the firm installation of the cabinet door 2 and the box door 1. And the cabinet door 2 can be conveniently installed on the outside of the box door 1, which is beneficial to reducing the labor intensity of the installer and improving the installation efficiency of the cabinet door 2.

[0081] In some embodiments, as Figure 1 shown, the support sleeve 31 is movably arranged on the box door 1 along the width direction of the box door 1, and the plug-in part 33 is arranged on the cabinet door 2.

[0082] It can be understood that the support sleeve 31 is arranged on the box door 1 and the plug-in part 33 is arranged on the cabinet door 2. During the installation of the cabinet door 2 towards the box door 1, the plug-in part 33 aligns with the pore of the support sleeve 31 and is inserted into the support sleeve 31. Installing the plug-in part 33 on the cabinet door 2 is more conducive to adjusting the position of the plug-in part 33 relative to the support sleeve 31, which is beneficial to improving the installation efficiency.

[0083] In some embodiments, as Figure 1 shown, the locking member 32 is movably inserted through the side wall of the support sleeve 31 and can be connected to the plug-in member 33 inserted into the support sleeve 31.

[0084] It can be understood that the locking member 32 is inserted through the side wall of the support sleeve 31 and can move relative to the support sleeve 31. When the plug-in member 33 is inserted into the support sleeve 31, the locking member 32 moves radially away from the axis of the support sleeve 31 relative to the side wall of the support sleeve 31 to create a moving space to allow the plug-in member 33 to be inserted into the support sleeve 31. Then, the locking member 32 moves radially closer to the axial direction of the support sleeve 31 relative to the side wall of the support sleeve 31 and connects to the plug-in member 33, limiting the plug-in member 33 within the support sleeve 31, so that the support sleeve 31 and the plug-in member 33 are firmly connected, thereby realizing the firm installation of the cabinet door 2 relative to the box door 1, and the structure is compact with a small installation space and is convenient for operation.

[0085] Specifically, the connection between the locking member 32 and the plug-in member 33 can be achieved by providing external threads on the locking member and threaded holes on the outer wall of the plug-in member, and the connection between the locking member and the plug-in member is realized based on the threaded connection between the external threads and the threaded holes. Alternatively, the connection between the locking member 32 and the plug-in member 33 can also be achieved through a snap-fit structure.

[0086] Optionally, the locking member 32 can be inserted through the bottom end of the side wall of the support sleeve 31 or through both sides of the side wall of the support sleeve 31.

[0087] In some embodiments, as Figure 1 and Figure 8 shown, the plug-in member 33 is provided with a limiting groove 331, and the locking member 32 is used to be inserted into the limiting groove 331 to lock the plug-in member 33 within the support sleeve 31.

[0088] It can be understood that the limiting groove 331 is arranged circumferentially around the plug-in member 33, which can be arranged in a whole circle or in segments, and the limiting groove 331 is arranged opposite to the locking member 32. When the locking member 32 is inserted into the limiting groove 331, the limiting groove 331 can limit the displacement of the plug-in member 33 relative to the locking member 32 along the axial direction of the plug-in member 33. Furthermore, the plug-in member 33 cannot move axially relative to the support sleeve 31, thereby locking the plug-in member 33 within the support sleeve 31, ensuring the firm connection between the support sleeve 31 and the plug-in member 33, and further ensuring the firm connection between the cabinet door 2 and the box door 1. Moreover, the limiting function can be achieved only by providing the limiting groove 331 on the plug-in member 33, and the structure is simple and easy to implement.

[0089] In some embodiments, as Figure 1 、 Figure 5 and Figure 8As shown, the locking member 32 is vertically movably disposed through the side wall of the support sleeve 31.

[0090] During the insertion of the plug member 33 into the support sleeve 31, the surface of the locking member 32 and the plug member 33 are in sliding fit, and then inserted into the limiting groove 331.

[0091] It can be understood that the locking member 32 of this embodiment is disposed through the top end of the side wall of the support sleeve 31 and can be vertically disposed through the side wall of the support sleeve 31.

[0092] Such as Figure 12 、 Figure 13 and Figure 1 , when the plug member 33 is inserted into the support sleeve 31, as the plug member 33 approaches the support sleeve 31, the plug member 33 pushes the locking member 32 upward. As the plug member 33 advances along the axial direction of the support sleeve 31, the plug member 33 continuously pushes the locking member 32 upward until the plug member 33 is installed in place relative to the support sleeve 31. At this time, the locking member 32 drops downward under the action of gravity and is inserted into the limiting groove 331 to complete the locking of the plug member 33, and the plug member 33 is limited within the support sleeve 31.

[0093] In this embodiment, by vertically movably disposing the locking member 32 through the side wall of the support sleeve 31, during the installation process of the plug member 33 and the support sleeve 31, the surface of the locking member 32 and the plug member 33 are in sliding fit to complete the lifting and avoidance and the downward limiting of the locking member 32, and finally the locking member 32 is inserted into the limiting groove 331 to complete the locking fit with the plug member 33. The cooperation with the limiting groove 331 is completed by the self-weight of the locking member 32, which is beneficial to the convenience of installation.

[0094] In some embodiments, such as Figure 6 、 Figure 7 and Figure 8 shown, the locking member 32 includes: a locking rod 321 and a locking tongue 322. The locking rod 321 is vertically disposed through the side wall of the support sleeve 31, and the upper end of the locking rod 321 is limited outside the support sleeve 31.

[0095] The locking tongue 322 is connected to the lower end of the locking rod 321, and the locking tongue 322 is in sliding fit with the surface of the plug member 33 and is used to be inserted into the limiting groove 331.

[0096] It can be understood that the support sleeve 31 of this embodiment includes a main body 311 and a limiting member 312. The limiting member 312 is disposed outside the top end of the main body 311. The locking rod 321 is vertically disposed through the top end of the side wall of the main body 311. The limiting member 312 outside the main body 311 can limit the locking rod 321, so that when the plug member 33 is inserted into the main body 311, the plug member 33 pushes the locking rod 321 to rise vertically, and the limiting member 312 can limit the upward movement of the locking rod 321 to prevent the locking rod 321 from falling off the main body 311.

[0097] Specifically, the limiting member 312 includes a limiting disk disposed opposite to the through hole on the body 311, and four legs evenly distributed around the limiting disk. One end of each leg is connected to the limiting disk, and the other end is connected to the body 311. An annular groove is provided at the upper end of the locking rod 321. When the upper end of the locking rod 321 passes through the circular hole on the limiting disk and rises, when the annular groove moves to the lower side of the limiting disk, the fitting between the annular groove wall and the limiting disk restricts further movement of the locking rod 321, thereby limiting the movement stroke of the locking rod 321.

[0098] One end of the locking tongue 322 of this embodiment close to the plug-in member 33 is provided with an inclined surface. When the plug-in member 33 is inserted into the body 311, the inclined surface contacts the surface of the plug-in member 33, which is more conducive to the upward lifting of the locking tongue 322 to avoid the plug-in member 33, and when the locking tongue 322 descends, the inclined surface can play a guiding role to guide the locking tongue 322 into the limiting groove 331.

[0099] In some embodiments, as Figure 1 and Figure 8 shown, the plug-in member 33 includes: a mounting seat 332 and a plug-in column 333.

[0100] The mounting seat 332 is provided on the door 1 of the box or the door 2 of the cabinet.

[0101] The plug-in column 333 is connected to the mounting seat 332. The plug-in column 333 is used to be inserted into the support sleeve 31, and a limiting groove 331 is provided on the peripheral wall of the plug-in column 333.

[0102] It can be understood that the mounting seat 332 of this embodiment is provided in the shape of a strip plate. The side with a larger area of the strip plate is attached and installed to the door 1 of the box or the door 2 of the cabinet, ensuring the installation strength of the plug-in member 33.

[0103] The plug-in column 333 is perpendicularly connected to the mounting seat 332. The limiting groove 331 provided on the peripheral wall of the plug-in column 333 is used to accommodate the locking member 32 to lock the locking member 32 in the support sleeve 31.

[0104] In some embodiments, as Figure 1 、 Figure 5 and Figure 8 shown, the plug-in column 333 includes: a plug-in head 3331, a limiting section 3332, and a stop section 3333.

[0105] The plug-in head 3331, the limiting section 3332, and the stop section 3333 are connected in sequence. One end of the stop section 3333 away from the limiting section 3332 is connected to the mounting seat 332.

[0106] The diameter of the limiting section 3332 is respectively smaller than the maximum outer diameters of the plug connector 3331 and the stop section 3333, so that a limiting groove 331 is formed between the plug connector 3331, the limiting section 3332 and the stop section 3333.

[0107] It can be understood that the plug connector 3331 of this embodiment is tapered, which is beneficial to the sliding fit between the plug connector 3331 and the locking member 32 when the plug connector 3331 pushes the locking member 32 to lift. Based on the fact that the diameter of the limiting section 3332 is smaller than the maximum outer diameters of the plug connector 3331 and the stop section 3333, a limiting groove 331 can be formed by enclosing between the plug connector 3331, the limiting section 3332 and the stop section 3333. The locking member 32 is inserted into the limiting groove 331, and the stop section 3333 and the plug connector 3331 limit the locking member 32 along the axial direction of the support sleeve 31. Therefore, the plug column 333 cannot fall off from the support sleeve 31, ensuring the firm installation of the plug column 333 and the support sleeve 31.

[0108] In some embodiments, as Figure 5 shown, the door assembly further includes: a first sliding module 4.

[0109] The first sliding module 4 includes a first slide rail 41 and a first sliding member 42. The first slide rail 41 and the first sliding member 42 are slidably engaged in the width direction. The first slide rail 41 is provided on the cabinet door 1, and the first sliding member 42 is connected to the support sleeve 31 or the plug-in member 33.

[0110] It can be understood that due to the self-weight of the cabinet door 2, the cabinet door 2 may vibrate or tilt during the process of moving relative to the cabinet door 1. The first sliding module 4 can provide stable support and guiding functions to guide the reliable and stable movement of the cabinet door 2 relative to the cabinet door 1.

[0111] The first sliding member 42 can move along the extending direction of the first slide rail 41. Based on the guiding and supporting functions of the first slide rail 41, the first sliding member 42 can move stably and reliably along the first slide rail 41. And, based on the high rigidity of the first slide rail 41, a high straightness can be provided for the first sliding member 42, so that the cabinet door 2 can move stably and reliably along the width direction of the cabinet door 1.

[0112] In some embodiments, as Figure 9 shown, the door assembly further includes: a second hanging structure 5.

[0113] The second hanging structure 5 is provided between the bottom end of the cabinet door 1 and the bottom end of the cabinet door 2, and can guide the cabinet door 2 to move relative to the cabinet door 1 in the width direction.

[0114] The first hanging structure 3 is provided between the top end of the cabinet door 1 and the top end of the cabinet door 2.

[0115] It is understandable that the second hanging structure 5 can adjust the position of the cabinet door 2 relative to the box door 1 in the width direction of the box door 1, so that the cabinet door 2 can avoid the cabinet doors 2 on both sides during the opening and closing process of the box door 1.

[0116] The first hanging structure 3 can connect and lock the top ends of the box body 8 and the cabinet door 2, and the second hanging structure 5 can connect and lock the bottom ends of the box door 1 and the cabinet door 2, so that the box door 1 and the cabinet door 2 can be connected simultaneously from the top and the bottom, improving the stability of the cabinet door 2 connected to the box door 1.

[0117] In some embodiments, as Figure 3 、 Figure 4 and Figure 9 shown, the second hanging structure 5 includes: a lapping member 51 and a hook 52. The lapping member 51 is movably arranged on the box door 1 in the width direction of the box door 1. The hook 52 is arranged on the cabinet door 2 and is hung on the lapping member 51.

[0118] It is understandable that the lapping member 51 of this embodiment is a plug-in slot formed by connecting three strip-shaped plates, and the hook 52 is hung in the plug-in slot to realize the connection between the hook 52 and the lapping member 51. Moreover, based on the limiting effect of the plug-in slot on the hook 52, it is difficult for the hook 52 to fall off from the plug-in slot after being installed in place, which is beneficial to the stable connection between the hook 52 and the plug-in slot.

[0119] As Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 1 shown, during the process of installing the cabinet door 2 to the box door 1, first bring the bottom end of the cabinet door 2 close to the bottom end of the box door 1, hang the hook 52 in the lapping member 51, and then bring the top end of the cabinet door 2 close to the top end of the box door 1, insert the plug-in member 33 into the support sleeve 31, and connect the locking member 32 with the plug-in member 33, so as to lock the plug-in member 33 in the support sleeve 31. In this way, the cabinet door 2 is installed in place on the box door 1, and the cabinet door 2 can also move relative to the box door 1 in the width direction of the box door 1.

[0120] In some embodiments, as Figure 9 shown, the door body assembly further includes: a second sliding module 6. The second sliding module 6 includes a second slide rail 61 and a second slider 62, the second slide rail 61 and the second slider 62 are slidably matched in the width direction, the second slide rail 61 is arranged on the box door 1, and the second slider 62 is connected with the lapping member 51.

[0121] It is understandable that the second sliding module 6 can provide stable support and guiding effects for the bottom end of the cabinet door 2, guiding the bottom end of the cabinet door 2 to move reliably and stably relative to the box door 1.

[0122] The second sliding member 62 can move along the extending direction of the second slide rail 61. Based on the guiding and supporting effects of the second slide rail 61, the second sliding member 62 can move stably and reliably along the second slide rail 61. Moreover, based on the high rigidity of the second slide rail 61, a high straightness can be provided for the second sliding member 62, so that the bottom end of the cabinet door 2 can move stably and reliably along the width direction of the box door 1.

[0123] The first sliding module 4 is arranged at the top end of the cabinet door 2, and the second sliding module 6 is arranged at the bottom end of the cabinet door 2. The first sliding module 4 and the second sliding module 6 cooperate to enable the cabinet door 2 to move stably and reliably along the width direction of the box door 1 relative to the box door 1.

[0124] In some embodiments, as Figure 14 shown, the door body assembly further includes: a sliding door mechanism 7. The sliding door mechanism 7 is configured to be arranged on the box body 8 or the box door 1 and is in transmission connection with the cabinet door 2. The sliding door mechanism 7 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.

[0125] The refrigeration device is configured to be arranged in the accommodation space between the first cabinet body 10 and the second cabinet body 11; during the opening or closing process of the box door 1, the sliding door mechanism 7 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 10 or the second cabinet body 11.

[0126] It can be understood that an opening is provided on the outer side of the accommodation space between the first cabinet body 10 and the second cabinet body 11. This design enables the refrigeration device to be integrally embedded in the cabinet body. 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 is configured to drive the cabinet door 2 to move a preset distance in the box door 1 in a direction away from or close to the box body 8, so that the cabinet door 2 avoids the side walls of the first cabinet body 10 and the second cabinet body 11.

[0127] 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 is configured to drive the cabinet door 2 to move in the box door 1 in a direction away from or close to the box body 8, 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 10 and the second cabinet body 11. Through the movement of the preset distance, the box 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.

[0128] In some embodiments, as Figure 14As shown, the cabinet door 1 is rotatably connected to the cabinet body 8 through a hinge 9; the door 2 can move between a first position and a second position along the width direction relative to the cabinet door 1.

[0129] When the door 2 is in the first position, the cabinet door 1 closes the storage compartment, and the side of the door 2 facing the hinge 9 is arranged close to the hinge 9.

[0130] When the door 2 is in the second position, the cabinet door 1 opens the storage compartment, and the side of the door 2 facing the hinge 9 is arranged away from the hinge 9 to avoid the side wall of the first cabinet body 10 or the second cabinet body 11.

[0131] It can be understood that the storage compartment is used to store items to be refrigerated or frozen. When the cabinet door 1 closes the storage compartment, the cabinet door 1 is in a closed state, and the side of the 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 door 2 and the side of the cabinet door 1 are flush. At this time, the door 2 can completely cover the cabinet door 1 to ensure that the door body of the accommodation space exposed by the refrigeration device is consistent with the surrounding first cabinet body 10 and second cabinet body 11 in appearance.

[0132] When the cabinet door 1 opens the storage compartment, the cabinet door 1 is in an open state, and the side of the 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 wall of the door 2 and the side wall of the cabinet door 1 are misaligned and form a gap that can accommodate the side of the first cabinet body 10 or the second cabinet body 11, so as to avoid collision or interference between the door 2 and the first cabinet body 10 or the second cabinet body 11 due to the opening of the cabinet door 1.

[0133] In some embodiments, as Figure 14 shown, the sliding door mechanism 7 includes: a triggering member and a linear driving member. The triggering member is used to obtain the opening and closing signal of the cabinet door 1. The linear driving member is arranged between the cabinet door 1 and the door 2 and is connected to the triggering member.

[0134] Among them, the linear driving member is used to drive the door 2 to move along the width direction of the cabinet door 1 according to the opening and closing signal fed back by the triggering member.

[0135] It can be understood that, as Figure 14 shown, a hinge 9 is installed at the vertex of the upper end of the cabinet body. An articulated shaft is provided on the hinge 9, and the cabinet door 1 is rotatably arranged on the articulated shaft to realize the opening or closing of the cabinet door 1 relative to the cabinet body 8.

[0136] The linear driving member is installed on the cabinet door 1, and the output end of the linear driving member is connected to the door 2. The triggering member is electrically connected to the linear driving member, or the triggering member is wirelessly communicatively connected to the linear driving member.

[0137] This embodiment further includes a controller. The trigger is electrically connected to the controller, and the controller is electrically connected to the linear drive. The controller is configured to receive the opening and closing signal of the cabinet door 1 fed back by the trigger and control the linear drive to drive the movement of the cabinet door 2.

[0138] Specifically, the trigger can be a photoelectric switch, which determines the opening and closing state of the cabinet door 1 by detecting the relative distance between the cabinet door 1 and the cabinet body 8. The trigger can also be an angle sensor, which determines the opening and closing state of the cabinet door 1 by detecting the relative angle between the cabinet door 1 and the cabinet body 8. The linear drive can be a cylinder, a hydraulic cylinder, or an electric push rod.

[0139] In practical applications, during the opening process of the cabinet door 1, the linear drive drives the cabinet door 2 to move away from the hinge 9 along the width direction of the cabinet door 1, that is, move to the left 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 drives the cabinet door 2 to move towards the hinge 9 along the width direction of the cabinet door 1, that is, move to the right 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.

[0140] For the sliding door mechanism 7 shown in this embodiment, by using the trigger to obtain the opening and closing signal of the cabinet door 1 and arranging a linear drive between the cabinet door 1 and the cabinet door 2. When the cabinet door 1 is opened, the linear drive drives the cabinet door 2 to move away from the hinge 9 along 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 drives the cabinet door 2 to move towards the hinge 9 along 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.

[0141] In some embodiments, as Figure 14 shown, the trigger 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.

[0142] 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 shaft of the hinge 9, and the angular displacement sensor can detect the rotation direction and rotation angle of the cabinet door 1 around the hinge shaft.

[0143] The displacement sensor can detect the rotation direction of the door 1 relative to the cabinet body 8 when the door 1 rotates. According to the opening and closing states of the door 1, the opening and closing signals are divided into an opening signal and a closing signal. When the door 1 is opened, the displacement sensor feeds back the opening signal to the linear drive member, and the linear drive member drives the cabinet door 2 to move away from the hinge 9 along the width direction of the door 1. Correspondingly, when the door 1 is closed, the displacement sensor feeds back the closing signal to the linear drive member, and the linear drive member drives the cabinet door 2 to move towards the hinge 9 along the width direction of the door 1.

[0144] Furthermore, as the opening or closing amplitude of the door 1 is different, the displacement sensor can also obtain the rotation angle of the door 1. The linear drive member can determine the preset value of the movement according to the rotation angle. When the door 1 is in the open state, according to the angle of rotation when the 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 with the external cabinet body. Correspondingly, when the door 1 is in the closed state, according to the angle of rotation when the 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 cabinet door 2 is reset.

[0145] In this embodiment, by setting the trigger member as a displacement sensor, the opening and closing signal and the rotation angle of the door 1 are obtained synchronously, and then the preset value of the movement of the cabinet door 2 along the width direction of the door 1 is accurately determined, so that the movement of the cabinet door 2 relative to the door 1 can be consistent with the rotation amplitude of the door 1, avoiding interference and ensuring the beauty and reliability of the movement process of the cabinet door 2 relative to the door 1.

[0146] In some embodiments, as Figure 14 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 door 1 to open and close.

[0147] It can be understood that the opening mechanism of this embodiment is used to open or close the door 1. The push-button switch is connected to the opening mechanism, and the push-button switch controls the opening mechanism to open the door 1 or close the door 1 when triggered.

[0148] Generally, built-in refrigerators are designed in a handleless style, using a pressure opening system or a hidden notch to replace the traditional handle, or a push-button switch can also be used to control the opening and closing of the door 1 of the built-in refrigerator. The push-button switch of this embodiment is arranged on the cabinet door of the refrigerator and is used to control the opening and closing of the 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 door 1 to the linear drive member, and the linear drive member drives the cabinet door 2 to move along the width direction of the door 1.

[0149] Specifically, after the button switch receives the input instruction for the opening of the cabinet door 1, the button switch feeds back the opening signal to the door opening mechanism and the linear drive member. The door opening mechanism drives the cabinet door 1 to open. At the same time, the linear drive member drives the cabinet door 2 to move away from the hinge 9 along the width direction of the cabinet door 1 to ensure that when the cabinet door 1 is opened, the cabinet door 2 does not interfere with the surrounding parts.

[0150] After the button switch receives the input instruction for the closing of the cabinet door 1, the button switch feeds back the closing signal to the door opening mechanism and the linear drive member. The door opening mechanism drives the cabinet door 1 to close. At the same time, the linear drive member drives the cabinet door 2 to move towards the hinge 9 along the width direction of the cabinet door 1 to ensure that when the cabinet door 1 is closed, the cabinet door 2 does not interfere with the surrounding parts, and the cabinet door 2 can be reset as the cabinet door 1 is completely closed to ensure the aesthetics of the cabinet door 2.

[0151] 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 signals of the cabinet door 1 to the linear drive member, so that the linear drive member drives the cabinet door 2 to move along 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.

[0152] In some embodiments, the linear drive member includes a linear motor or a telescopic rod.

[0153] It can be understood that as Figure 14 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 to realize the movement of the cabinet door 2 along the width direction of the cabinet door 1. The reaction speed of the linear motor is fast and the sensitivity is high. For the movement adjustment of the cabinet door 2 within a small distance range along the cabinet door 1, it can quickly respond and accurately adjust the movement distance, realizing the reliability and stability of the movement of the cabinet door 2 relative to the cabinet door 1.

[0154] 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 along 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.

[0155] Specifically, the telescopic rod can be an electric push rod or a cylinder.

[0156] In a second aspect, as Figure 14 and Figure 15 shown, an embodiment of the present utility model further provides a refrigeration device, including: a box body 8 and the door body assembly as above. The box body 8 has a storage compartment, and the box door 1 is rotatably arranged on the box body 8 to open or close the storage compartment.

[0157] It can be understood that the door body device in this embodiment can be used in refrigeration devices such as refrigerators, freezers, ice makers, etc.

[0158] Among them, the thickness of the box door 1 is 18 - 60 mm. For example, the thickness of the box door 1 can be 18 mm, 25 mm, 35 mm, 50 mm, 55 mm or 60 mm; the thickness of the cabinet door 2 is 12 - 26 mm. For example, the thickness of the cabinet door 2 can be 12 mm, 15 mm, 20 mm or 26 mm; the cabinet door 2 can be a wooden door panel or a plastic door panel.

[0159] Specifically, since the refrigeration device includes a door body assembly, and the specific structure of the door body assembly refers to the above embodiment, the refrigeration device shown in this embodiment includes all the technical solutions of the above embodiment. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above embodiment, which will not be elaborated here one by one.

[0160] 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, the cabinet door 2 with the same material and color as the surrounding cabinet is installed on the outer side of the box door 1.

[0161] The refrigeration device of this embodiment can install the cabinet door 2 on the box door 1 through the first hanging structure 3, and the cabinet door 2 can be locked on the box door 1, realizing the firm installation of the cabinet door 2 on the box door 1. Moreover, the cabinet door 2 can also move along the width direction of the box door 1, meeting the opening and closing requirements of the box door 1 for the storage compartment.

[0162] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model, rather than to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present utility model do not depart from the spirit and scope of the technical solutions of the present utility model, and should all be covered within the scope of the claims of the present utility model.
