[0047] The following is combined with Figures 1 to 4, 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.

[0048] 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.

[0049] The cabinet door 1 is configured to be rotatably disposed on a cabinet body 5 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 5 .

[0050] The hanging structure 3 includes a supporting member 31, an overlapping portion 32 and a locking member 33; the supporting member 31 is movably arranged on the cabinet door 1 along the width direction of the cabinet door 1, and the overlapping portion 32 is arranged on the cabinet door 2; the supporting member 31 and the overlapping portion 32 are abutted against each other along the height direction of the cabinet door to support the cabinet door 2; the locking member 33 is used to realize the locking connection between the supporting member 31 and the cabinet door 2.

[0051] 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.

[0052] It is understandable that the box body 5 of this embodiment is equipped with a hinge 6, and a hinge shaft is provided on the hinge 6. 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 5. 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.

[0053] In the present embodiment, a slide rail is arranged on the cabinet door 1, and the slide rail is extended along the width direction of the cabinet door 1. The supporting member 31 is arranged on the slide rail and can move along the extension direction of the slide rail. The overlapping part 32 is connected to the cabinet door 2. The supporting member 31 supports the cabinet door 2 through the upper and lower abutment between the supporting member 31 and the overlapping part 32, thereby realizing the installation connection between the cabinet door 1 and the cabinet door 2.

[0054] Specifically, the supporting member 31 may be a buckle or a slider; the overlapping portion 32 may be a groove or a protrusion, and it is only necessary to ensure the abutting installation between the supporting member 31 and the overlapping portion 32 .

[0055] Further, a locking member 33 is provided between the supporting member 31 and the lapping portion 32. When installing the cabinet door 1 and the cupboard door 2, after the supporting member 31 and the lapping portion 32 are installed and abutted in place, to ensure that there is no relative shaking and dislocation between the supporting member 31 and the lapping portion 32 during the opening and closing process of the cabinet door 1, the locking member 33 is used to realize the locking connection between the supporting member 31 and the cupboard door 2, so that the supporting member 31 and the lapping portion 32 are stably and reliably connected, and further the cabinet door 1 and the cupboard door 2 are stably and reliably connected.

[0056] Specifically, the locking member 33 can be locked by threads, or can be locked by fasteners, or can also be locked by a buckle.

[0057] For the door body assembly shown in this embodiment, by providing a hanging structure 3 between the cabinet door 1 and the cupboard door 2, and providing a supporting member 31, a lapping portion 32 and a locking member 33 in the hanging structure 3, the lapping portion 32 is arranged on the cupboard door 2, the supporting member 31 abuts against the lapping portion 32 up and down to support the cupboard door 2, and the locking member 33 is used to realize the locking connection between the supporting member 31 and the cupboard door 2, so that during the installation process of the cabinet door 1 and the cupboard door 2, it is only necessary to abut the supporting member 31 against the lapping portion 32, and then lock the locking member 33 to the supporting member 31 and the cupboard door 2, and the installation process is completed, improving the installation efficiency of the cupboard door 2 and the cabinet door 1, saving installation time, and, the supporting member 31 is movably arranged on the cabinet door 1 along the width direction of the cabinet door 1, and the movement of the supporting member 31 can also drive the movement of the cupboard door 2 along the width direction of the cabinet door 1, avoiding the interference between the cupboard door 2 and the cabinet body of the surrounding cabinets and meeting the opening and closing requirements of the cabinet door 1.

[0058] In some embodiments, such as Figure 1 and Figure 2 shown, the lapping portion 32 includes an installation groove 321, and the installation groove 321 is arranged on one side of the cupboard door 2 facing the cabinet door 1.

[0059] The supporting member 31 is embedded in the installation groove 321 and abuts against the top groove wall of the installation groove 321.

[0060] It can be understood that the lapping portion 32 of this embodiment is configured as an installation groove 321 arranged on the cupboard door 2. Through the embedded fit between the installation groove 321 and the supporting member 31, and the supporting member 31 abuts against the top groove wall of the installation groove 321, the supporting member 31 supports the cupboard door 2. By arranging the installation groove 321 on the cupboard door 2, the overall structure of the door body assembly is relatively compact, and, the weight of the cupboard door 2 is also reduced, and, through the cooperation between the installation groove 321 and the supporting member 31, the convenient installation of the cabinet door 1 and the cupboard door 2 is realized.

[0061] In some embodiments, such as Figure 1 and Figure 2As shown, the installation groove 321 extends in the width direction, and the supporting member 31 is movably disposed in the installation groove 321 in the width direction to reach a position opposite to the locking position on the cabinet door 2. Among them, when the supporting member 31 reaches the locking position, the locking member 33 locks between the supporting member 31 and the cabinet door 2.

[0062] It can be understood that when the supporting member 31 reaches the position opposite to the locking position, the box door 1 and the cabinet door 2 are in the optimal installation position, the cabinet door 2 completely covers the box door 1, and the installation path of the supporting member 31 is along the width direction of the cabinet door 2.

[0063] When assembling the supporting member 31 and the cabinet door 2, first embed the supporting member 31 into the installation groove 321, and slide it in the installation groove 321 in the width direction so that the supporting member 31 moves to the locking position, and lock and connect the supporting member 31 and the cabinet door 2 at the locking position.

[0064] In this embodiment, by arranging the installation groove 321 in the width direction, the supporting member 31 can move in the installation groove 321 in the width direction. After being adjusted to the locking position, the supporting member 31 is locked on the cabinet door 2. The specific position of the locking position can be set according to the relative width of the box door 1 and the cabinet door 2, and the position of the locking position can be finely adjusted at the installation site, increasing the flexibility of installing the cabinet door 2.

[0065] In some embodiments, as Figure 1 and Figure 2 shown, the supporting member 31 is embedded into the installation groove 321 in the thickness direction of the cabinet door 2 to reach a position opposite to the locking position on the cabinet door 2. Among them, when the supporting member 31 reaches the locking position, the locking member 33 locks between the supporting member 31 and the cabinet door 2.

[0066] It can be understood that the installation groove 321 extends in the thickness direction of the cabinet door 2, the locking position is arranged on the installation groove 321 along the thickness direction of the cabinet door 2, and the installation path of the supporting member 31 is along the thickness direction of the cabinet door 2.

[0067] When assembling the supporting member 31 and the cabinet door 2, first embed the supporting member 31 into the installation groove 321, and move the supporting member 31 in the thickness direction so that the supporting member 31 reaches the locking position, and lock and connect the supporting member 31 and the cabinet door 2 at the locking position.

[0068] In this embodiment, by arranging the installation groove 321 in the thickness direction, when installing, the supporting member 31 is embedded into the installation groove 321 in the thickness direction and moved to a position opposite to the locking position. At the installation site, the supporting member 31 can reach the locking position by only pushing it in the thickness direction in the installation groove 321, simplifying the installation operation and conveniently realizing the installation of the cabinet door 2 and the box door 1.

[0069] In some embodiments, as Figure 1and Figure 2 As shown in Figure 2 , the locking member 33 includes a driving member 331 and a locking pin 332, and the driving member 331 is connected to the locking pin 332; a locking hole 21 is provided at the locking position of the cabinet door 2, and the driving member 331 is used to drive the locking pin 332 to extend into the locking hole 21.

[0070] It can be understood that the driving member 331 is connected to the supporting member 31, one end of the locking pin 332 is connected to the driving member 331, and when the other end of the locking pin 332 extends into the locking hole 21, since the supporting member 31 is connected to the box door 1 and the locking hole 21 is provided on the cabinet door 2, the cooperation between the locking pin 332 and the locking hole 21 enables a locking connection between the supporting member 31 and the cabinet door 2, and the supporting member 31 is firmly limited to the cabinet door 2.

[0071] Specifically, the driving member 331 can be a telescopic rod, a gear assembly, or a link and gear structure.

[0072] In this embodiment, by setting the locking member 33 as the driving member 331 and the locking pin 332, when installing the supporting member 31 and the cabinet door 2, the driving member 331 drives the locking pin 332 to extend into the locking hole 21 to achieve the locking connection between the supporting member 31 and the cabinet door 2. The installation process is fast and convenient, and the structure is compact.

[0073] In some embodiments, as Figure 1 and Figure 2 shown, the driving member 331 includes an elastic member, and the elastic member and at least part of the locking pin 332 are arranged in the mounting hole 311 on the supporting member 31.

[0074] In the case where the supporting member 31 reaches the locking position, the mounting hole 311 and the locking hole 21 are oppositely arranged, and the elastic member is used to drive part of the locking pin 332 to expose from the mounting hole 311 and extend into the locking hole 21.

[0075] It can be understood that the elastic member and the locking pin 332 are arranged in the mounting hole 311, and the elastic member and the locking pin 332 can move in the mounting hole 311.

[0076] During the installation process, the supporting member 31 is pushed towards the locking position close to the mounting groove 321. When the locking pin 332 reaches the locking hole 21 on the cabinet door 2, the elastic member is elastically deformed to push the locking pin 332 into the locking hole 21, so that part of the locking pin 332 exposes from the mounting hole 311 and extends into the locking hole 21, and the remaining part of the locking pin 332 is still in the mounting hole 311. At this time, the elastic force of the compressed elastic member keeps the supporting member 31 in the locking position to prevent accidental loosening or movement of the supporting member 31.

[0077] Specifically, the elastic member can be a locking spring.

[0078] In some embodiments, as Figure 1 and Figure 2As shown, the keyhole 21 is provided on the top wall of the installation groove 321. When the supporting member 31 reaches the locking position, the keyhole 21 is vertically opposite to the installation hole 311. The elastic member abuts between the bottom of the installation hole 311 and the lower end of the locking pin 332. The lower end of the locking pin 332 is located in the installation hole 311, and the upper end of the locking pin 332 is located in the keyhole 21.

[0079] It can be understood that when the supporting member 31 reaches the locking position of the cabinet door 2 and is locked and connected to the cabinet door 2, the supporting member 31 abuts on the top wall of the installation groove 321. The cabinet door 2 is hung on the box door 1 through the locking pin 332. The gravity of the cabinet door 2 makes the connection between the locking pin 332 and the keyhole 21 more firm. Based on the connection of the locking pin 332 to the supporting member 31 and the cabinet door 2, the installation of the cabinet door 2 relative to the supporting member 31 is more stable and reliable.

[0080] In some embodiments, as Figure 1 and Figure 2 shown, the installation groove 321 has a notch end and a bottom end. The notch width of the installation groove 321 gradually decreases from the notch end to the bottom end. The supporting member 31 and the installation groove 321 are adapted in shape.

[0081] It can be understood that the widths of the notch end and the bottom end of the installation groove 321 are different and gradually decrease from the notch end to the bottom end. And the supporting member 31 and the installation groove 321 are adapted in shape and also have a shape with a gradually decreasing width, so that when the supporting member 31 is installed into the installation groove 321, the fitting degree between the installation groove 321 and the supporting member 31 is higher, and the supporting member 31 is less likely to fall off from the installation groove 321.

[0082] Specifically, the installation groove 321 can be set as a trapezoidal groove. The notch end corresponds to the long side of the trapezoid, and the bottom end corresponds to the short side of the trapezoid.

[0083] In a second aspect, as Figure 3 and Figure 4 shown, an embodiment of the present invention further provides a refrigeration device, including: a box body 5 and the door body assembly as above. The box body 5 has a storage compartment. The box door 1 is rotatably provided on the box body 5 to open or close the storage compartment.

[0084] Specifically, since the refrigeration device includes a door body assembly, and the specific structure of the door body 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 obtained by all the technical solutions of the above embodiments, which will not be elaborated one by one here.

[0085] 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 of the refrigeration device with the surrounding cabinet, a cabinet door 2 with the same material and color as the surrounding cabinet is installed on the outside of the box door 1.

[0086] The refrigeration device of this embodiment can facilitate the installation of the cabinet door 1 and the door 2, improve the installation efficiency of the door 2 and the cabinet door 1, and ensure the installation position accuracy of the door relative to the cabinet door.

[0087] Specifically, the refrigeration device of this embodiment is provided with four sets of door body assemblies, two of which are arranged along the width direction and are located between the upper end of the cabinet door 1 and the upper end of the door 2, and the other two sets of door body assemblies are arranged along the width direction and are located between the lower end of the cabinet door 1 and the lower end of the door 2, and the slide rails among the four sets of door body assemblies are all arranged in parallel.

[0088] In some embodiments, as Figure 3 shown, the refrigeration device further includes: a sliding door mechanism 4, which is configured to be arranged on the cabinet body 5 or the cabinet door 1 and is in transmission connection with the door 2, and the sliding door mechanism 4 is used to drive the door 2 to move relative to the cabinet door 1 along the width direction during the opening and closing process of the cabinet door 1.

[0089] The refrigeration device is configured to be arranged in the accommodation space between the first cabinet body 7 and the second cabinet body 8; during the opening or closing process of the cabinet door 1, the sliding door mechanism 4 is used to change the position of the door 2 on the cabinet door 1 so that the door 2 avoids the side walls of the first cabinet body 7 or the second cabinet body 8.

[0090] It can be understood that there is an opening on the outside of the accommodation space between the first cabinet body 7 and the second cabinet body 8, and 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 is configured to drive the door 2 to move a preset distance away from or close to the cabinet body 5 on the cabinet door 1 so that the door 2 avoids the side walls of the first cabinet body 7 and the second cabinet body 8.

[0091] 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 4 is configured to drive the door 2 to move away from or close to the cabinet body 5 on the cabinet door 1, and can also control the door 2 to move a preset distance. This design is mainly to avoid interference between the door 2 and the side walls of the first cabinet body 7 and the second cabinet body 8. 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.

[0092] In some embodiments, as Figure 3 shown, the sliding door mechanism 4 is connected to the supporting member 31 to drive the supporting member 31 to move relative to the cabinet door 1 along the width direction.

[0093] It is understandable that the supporting member 31 is movably connected to the box door 1, and the overlapping portion 32 is provided on the cabinet door 2. During the opening and closing process of the box door 1, the sliding door mechanism 4 drives the supporting member 31 to move relative to the box door 1 in the width direction, that is, drives the cabinet door 2 to move relative to the box door 1, ensuring that the cabinet door 2 does not interfere with the side cabinet body.

[0094] In some embodiments, as Figure 3 shown, the box door 1 is rotatably connected to the box body 5 through a hinge 6; the cabinet door 2 can move between a first position and a second position relative to the box door 1 in the width direction.

[0095] When the cabinet door 2 is in the first position, the box door 1 closes the storage compartment, and the side of the cabinet door 2 facing the hinge 6 is arranged close to the hinge 6.

[0096] When the cabinet door 2 is in the second position, the box door 1 opens the storage compartment, and the side of the cabinet door 2 facing the hinge 6 is arranged away from the hinge 6 to avoid the side wall of the first cabinet body 7 or the second cabinet body 8.

[0097] It is understandable that the storage compartment is used to store items to be refrigerated or frozen. When the box door 1 closes the storage compartment, the box door 1 is in a closed state, and the side of the cabinet door 2 is at a first distance (close to zero) relative to the hinge 6 of the refrigeration device. For example, the side of the cabinet door 2 and the side of the box door 1 are flush. At this time, the cabinet door 2 can completely block the box door 1, ensuring that the door body of the refrigeration device exposed in the accommodation space is consistent with the surrounding first cabinet body 7 and second cabinet body 8 in appearance.

[0098] When the box door 1 opens the storage compartment, the box door 1 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 6 of the refrigeration device. For example, the side wall of the cabinet door 2 and the side wall of the box door 1 are misaligned, 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 avoid collision or interference between the cabinet door 2 and the first cabinet body 7 or the second cabinet body 8 caused by the opening of the box door 1.

[0099] In some embodiments, as Figure 3 shown, the sliding door mechanism 4 includes: a triggering member and a linear driving member.

[0100] The triggering member is used to obtain the opening and closing signal of the box door 1.

[0101] The linear driving member is arranged between the box door 1 and the cabinet door 2 and is connected to the triggering member.

[0102] Among them, the linear driving member is used to drive the cabinet door to move in the width direction of the box door according to the opening and closing signal fed back by the triggering member.

[0103] It is understandable that, as Figure 3As shown, a hinge 6 is installed at the vertex of the upper end of the box body. An articulated shaft is provided on the hinge 6, and the box door 1 is rotatably arranged on the articulated shaft to realize the opening or closing of the box door 1 relative to the box body 5.

[0104] The linear drive is installed on the box door 1, and the output end of the linear drive is connected to the cabinet door 2. The trigger is electrically connected to the linear drive, or the trigger is wirelessly communicatively connected to the linear drive.

[0105] 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 box door 1 fed back by the trigger and control the linear drive to drive the movement of the cabinet door 2.

[0106] Specifically, the trigger can be a photoelectric switch, which judges the opening and closing state of the box door 1 by detecting the relative distance between the box door 1 and the box body 5. The trigger can also be an angle sensor, which judges the opening and closing state of the box door 1 by detecting the relative angle between the box door 1 and the box body 5. The linear drive can be a cylinder, a hydraulic cylinder, or an electric push rod.

[0107] In practical applications, during the opening process of the box door 1, the linear drive drives the cabinet door 2 to move in the width direction of the box door 1 away from the hinge 6, that is, move to the left relative to the box door 1, so as to avoid interference between the cabinet door 2 and the cabinet around the refrigeration equipment. During the closing process of the box door 1, the linear drive drives the cabinet door 2 to move in the width direction of the box door 1 towards the hinge 6, that is, move to the right relative to the box door 1, so as to ensure that the cabinet door 2 can avoid the cabinet around the refrigeration equipment when the box door 1 is closed and reset the cabinet door 2.

[0108] For the sliding door mechanism 4 shown in this embodiment, by using the trigger to obtain the opening and closing signal of the box door 1 and setting a linear drive between the box door 1 and the cabinet door 2, when the box door 1 is opened, the linear drive drives the cabinet door 2 to move in the width direction of the box door 1 away from the hinge 6, so that the cabinet door 2 does not interfere with the cabinet on the side. When the box door 1 is closed, the linear drive drives the cabinet door 2 to move in the width direction of the box door 1 towards the hinge 6, so that the cabinet door 2 returns to its original position, ensuring that the cabinet door 2 does not interfere with the cabinet around the refrigeration equipment.

[0109] In some embodiments, as Figure 3 shown, the trigger includes a displacement sensor, and the displacement sensor is used to detect the rotation direction of the box door 1 to obtain the opening and closing signal.

[0110] 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 articulated shaft of the hinge 6, and the angular displacement sensor can detect the rotation direction and rotation angle of the box door 1 around the articulated shaft.

[0111] When the displacement sensor can detect the rotation direction of the door 1 relative to the box body 5 when the door 1 of the box rotates, according to the opening and closing states of the door 1 of the box, the opening and closing signals are divided into an opening signal and a closing signal; when the door 1 of the box 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 6 in the width direction of the door 1 of the box; correspondingly, when the door 1 of the box 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 6 in the width direction of the door 1 of the box.

[0112] Furthermore, as the opening or closing amplitude of the door 1 of the box is different, the displacement sensor can also obtain the rotation angle of the door 1 of the box, and the linear drive member can determine the preset value of the movement according to the rotation angle. In the case where the door 1 of the box is in the open state, according to the rotation angle when the door 1 of the box 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 6 to avoid interference with the external cabinet body; correspondingly, in the case where the door 1 of the box is in the closed state, according to the rotation angle when the door 1 of the box 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 6 to avoid interference between the cabinet door 2 and the external cabinet body, and finally, the cabinet door 2 is reset.

[0113] 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 of the box are synchronously obtained, and then the preset value of the movement of the cabinet door 2 in the width direction of the door 1 of the box is accurately determined, so that the movement of the cabinet door 2 relative to the door 1 of the box can be consistent with the rotation amplitude of the door 1 of the box, which not only avoids interference but also ensures the beauty and reliability of the movement process of the cabinet door 2 relative to the door 1 of the box.

[0114] In some embodiments, as Figure 3 shown, the trigger member includes a push-button switch, and the push-button switch is used to receive the pressing input corresponding to the opening and closing signal; the push-button switch is configured to be connected to the opening mechanism that drives the door 1 of the box to open and close.

[0115] It can be understood that the opening mechanism of this embodiment is used to open or close the door 1 of the box, the push-button switch is connected to the opening mechanism, and the push-button switch controls the opening mechanism to open or close the door 1 of the box when triggered.

[0116] Generally, built-in refrigerators are designed in a handleless style, using a pressure opening system or a hidden notch to replace the traditional handle. Alternatively, a button switch can also be used to control the opening and closing of the door 1 of the built-in refrigerator. The button switch in 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 button switch. At the same time, the button switch feeds back the opening and closing signals 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.

[0117] Specifically, after the button switch receives the input instruction to open the 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 door 1 to open. At the same time, the linear drive member drives the cabinet door 2 to move along the width direction of the door 1 away from the hinge 6 to ensure that when the door 1 is opened, the cabinet door 2 does not interfere with the surrounding parts.

[0118] After the button switch receives the input instruction to close the 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 door 1 to close. At the same time, the linear drive member drives the cabinet door 2 to move along the width direction of the door 1 towards the hinge 6 to ensure that when the 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 door 1 is completely closed to ensure the aesthetics of the cabinet door 2.

[0119] 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 door 1 by driving the door opening mechanism, but also feed back the opening and closing signals of the 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 door 1, enabling the cabinet door 2 to open and close synchronously with the door 1 while avoiding interference with the surrounding cabinet body, ensuring the synchronism and aesthetics of the opening and closing of the door 1 and the cabinet door 2.

[0120] In some embodiments, the linear drive member includes a linear motor or a telescopic rod.

[0121] It can be understood that as Figure 3 shown, the linear motor is installed on the door 1, and the output end of the linear motor is connected to the cabinet door 2. The linear motor drives the cabinet door 2 to move along the width direction of the door 1 through linear drive. The reaction speed of the linear motor is fast and the sensitivity is high. For the small-distance movement adjustment of the cabinet door 2 along the 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 door 1.

[0122] 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 extending and retracting the telescopic rod, the distance between the rotation center of the cabinet door 2 and the cabinet door 1 is adjusted, so as to realize 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.

[0123] Specifically, the telescopic rod can be an electric push rod or a cylinder.

[0124] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered by the scope of the claims of the present invention.
