Exemplarily, the thickness of the cabinet door 200 is 12 mm, 18 mm, 24 mm, 26 mm, etc. In addition, the cabinet door 200 can be a wooden door or a plastic door, etc.

[0061] 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. Among them, the refrigeration device includes a box body 500, and the box body 500 forms a storage space, and items such as vegetables and fruits that need to be refrigerated or frozen can be placed in the storage space. Optionally, a refrigeration device and the like are also provided in the box body 500 of the refrigeration device, and the refrigeration device can perform refrigeration treatment on the storage space.

[0062] In this embodiment, the door body device includes a plurality of door body components 100. For example, the number of door body components 100 can be two, three, or four, and the plurality of door body components 100 are arranged at intervals in the height direction of the box body 500. Exemplarily, Figure 3 the door body device shown in includes two door body components 100.

[0063] Further, each door body component 100 includes a box door 110, a cabinet door 200, and at least one sliding door mechanism 300.

[0064] Among them, the multiple door body components 100 include two door body components. For example, the two door body components are a first door body component and a second door body component respectively. The first door body component is located above the second door body component. The cabinet doors 110 of the first door body component and the second door body component can be respectively rotatably connected to the cabinet body 500 through hinges 400.

[0065] The first door body component is correspondingly connected with two hinges 400. The cabinet door 110 in the first door body component is rotatably connected to the cabinet body 500 through the hinge shafts of the two hinges 400. The hinge shaft of one hinge 400 is located at the top of the cabinet door 110 in the first door body component, and the hinge shaft of the other hinge 400 is located at the bottom of the cabinet door 110 in the first door body component. At the same time, traction components 310 are respectively arranged on the two hinges. The second door body component is correspondingly connected with one hinge 400. The cabinet door 110 in the second door body component is rotatably connected to the cabinet body 500 through the hinge shaft of the hinge 400. The hinge shaft of the hinge 400 is located at the top of the cabinet door 110 in the second door body component. At the same time, the hinge is also provided with a traction component 310.

[0066] In this embodiment, the cabinet door 110 can be used to open or close the storage space in the cabinet body 500. When the cabinet door 110 is in the closed position for closing the storage space, the storage space is in a closed state, and the items in the storage space can be refrigerated. When the cabinet door 110 is in the open position for opening the storage space, the storage space is in an open state, and the user can take out the items in the storage space.

[0067] For the convenience of describing the positional relationship between various components, in this embodiment, as Figure 3 shown, the cabinet body 500 is generally constructed as a cuboid structure with a certain height. The cabinet body 500 can be placed on a horizontal plane. The cabinet body 500 has a height direction, a width direction, and a thickness direction that are perpendicular to each other. Among them, the height direction of the cabinet body 500 is parallel to the vertical direction, and the width direction and the thickness direction are located in the horizontal plane and are perpendicular to each other.

[0068] A storage space is arranged inside the cabinet body 500. An opening is arranged on the side part of the cabinet body 500 in the thickness direction. The opening communicates with the storage space. The cabinet door 110 is connected to the side part of the cabinet body 500 in the thickness direction where the opening is arranged. The cabinet door 110 extends along the width direction of the cabinet body 500. The cabinet door 110 is connected with a hinge 400 on one side in the width direction of the cabinet body 500. The cabinet door 110 can be rotatably connected to the cabinet body 500 through the hinge 400, so as to ensure that the cabinet door 110 can open or close the storage space of the cabinet body 500.

[0069] Moreover, the side of the cabinet body 500 where the cabinet door 110 is installed is the front side, that is, the cabinet door 110 is installed on the front side of the cabinet body 500.

[0070] The box door 110 generally has a flat plate-like structure with a certain thickness. The box door 110 has a height direction, a width direction, and a thickness direction that are perpendicular to each other. Among them, the height direction of the box door 110 is parallel to the vertical direction, and the width direction and the length direction are located in the horizontal plane and are perpendicular to each other. One side of the box door 110 in the width direction can be rotatably connected to the box body 500 via a hinge 400. For example, as Figure 3 shown, a hinge 400 is connected to the right side of the box door 110 in the width direction of the box body 500, and the box door 110 can be rotatably connected to the box body 500 via this hinge 400.

[0071] Moreover, when the box door 110 is in the position state of closing the storage space of the box body 500, the width direction of the box door 110 is parallel to the width direction of the box body 500, and the thickness direction of the box door 110 is parallel to the thickness direction of the box body 500.

[0072] Furthermore, the cabinet door 200 can be a decorative door panel. The cabinet door 200 is constructed as a flat plate-like structure with a certain thickness. The cabinet door 200 is connected to the outer side of the box door 110 facing away from the box body 500. When the refrigeration device is placed in the cabinet in an embedded manner or directly placed in the cabinet, after the box door 110 is in the closed position, the cabinet door 200 can be flush with the door panel of the cabinet, that is, the outer wall surface of the cabinet door 200 facing away from the box door 110 can be flush with the outer wall surface of the cabinet.

[0073] In the actual use scenario, the outer wall surface of the cabinet door 200 can be selected to have the same material and shape as the outer wall surface of the cabinet, and the same decoration can be attached to make the refrigeration device have sufficient coordination with the cabinet and ensure the aesthetics.

[0074] After the door body device in this embodiment is installed on the box body 500 of the refrigeration device, a plurality of door body components 100 can be arranged at intervals along the height direction of the box body 500. When each box door 110 in the door body component 100 can rotate to open or close the storage space of the box body 500 relative to the box body 500, the sliding door mechanism 300 can drive the cabinet door 200 to move relative to the box door 110 in the width direction of the box door 110. Thus, when the refrigeration device is placed in the cabinet in an embedded manner, it is possible to avoid interference between the cabinet door 200 and the cabinet during the process of opening the box door 110 while ensuring coordination, aesthetics, and not affecting the user experience.

[0075] In one embodiment, as Figure 4As shown, the door body device and the box body 500 are configured to be arranged in the installation space formed between the first cabinet body 510 and the second cabinet body 520; during the process of opening or closing the box door 110, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the box door 110, so that the cabinet door 200 avoids the side walls of the first cabinet body 510 and the second cabinet body 520.

[0076] Alternatively, the door body device and the box body 500 are configured to be arranged in the cabinet body; during the process of opening or closing the box door 110, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the box door 110, so that the cabinet door 200 avoids the side walls of the cabinet body.

[0077] It can be understood that the refrigeration device includes the door body device and the box body 500.

[0078] In practice, as Figure 4 shown, when the refrigeration device with the door body device and the box body 500 is placed between the adjacent first cabinet body 510 and the second cabinet body 520, multiple door body components 100 in the door body device can be arranged at intervals along the height direction of the box body 500, and the cabinet door 200 is arranged on the outer side of the box door 110 in each door body component 100, and the cabinet door 200 can move relative to the box door 110 along the width direction of the box door 110. Optionally, when the box door 110 is in the state of closing the storage space of the box body 500, the outer wall surface of the cabinet door 200 facing away from the box door 110 can be flush with the outer wall surfaces of the first cabinet body 510 and the second cabinet body 520, and the outer wall surfaces of the first cabinet body 510 and the second cabinet body 520 and the outer wall surface of the cabinet door 200 facing away from the box door 110 are in the same direction in the thickness direction of the box body 500.

[0079] At this time, during the process of the box door 110 rotating relative to the box body 500, the sliding door mechanism 300 can drive the cabinet door 200 to move, so that the cabinet door 200 avoids the side walls of the first cabinet body 510 and the second cabinet body 520.

[0080] Alternatively, after the refrigeration device is placed in the cabinet body, the cabinet door 200 can be arranged on the outer side of the box door 110 in each door body component 100, and the cabinet door 200 can move relative to the box door 110. Optionally, when the box door 110 is in the state of closing the storage space of the box body 500, the outer wall surface of the cabinet door 200 facing away from the box door 110 can be flush with the outer wall surface of the cabinet body, and the outer wall surface of the cabinet body and the outer wall surface of the cabinet door 200 facing away from the box door 110 are in the same direction in the thickness direction of the box body 500.

[0081] At this time, during the process of the box door 110 rotating relative to the box body 500, the sliding door mechanism 300 can drive the cabinet door 200 to move, and can also make the cabinet door 200 avoid the side walls of the cabinet body.

[0082] Further, in the sliding door mechanism 300 of the present embodiment, as Figure 10 and Figure 12 shown, the sliding door mechanism 300 includes a connected traction assembly 310 and a sliding door assembly 320. The traction assembly 310 can be disposed on the hinge 400, the sliding door assembly 320 can be disposed on the cabinet door 110, and the sliding door assembly 320 can also be connected to the cabinet door 200. During the rotation of the cabinet door 110 relative to the cabinet body 500, the traction assembly 310 can drive the sliding door assembly 320 to act, and thereby drive the cabinet door 200 to move relative to the cabinet door 110.

[0083] Exemplarily, since the hinge 400 is fixedly connected to the cabinet body 500, during the rotation of the cabinet door 110 relative to the cabinet body 500, the traction assembly 310 can apply a pulling force to the sliding door assembly 320, and then the sliding door assembly 320 drives the cabinet door 200 to move based on this pulling force.

[0084] Thus, when the door body device in the present embodiment is installed on the cabinet body 500 of the refrigeration device, a plurality of door body assemblies 100 can be arranged at intervals along the height direction of the cabinet body 500. Each door body assembly 100 can correspond to at least one storage space of the cabinet body 500. During the rotation of the cabinet door 110 in each door body assembly 100 relative to the cabinet body 500, the sliding door assembly 320 can drive the cabinet door 200 to move relative to the cabinet door 110 under the drive of the traction assembly 310. Therefore, when the refrigeration device is placed in the cabinet in an embedded manner, without affecting the coordination, aesthetics and the user experience, interference between the cabinet door 200 and the cabinet can be avoided during the opening of the cabinet door 110.

[0085] Further, in one embodiment, as Figure 3 shown, the hinge 400 includes a first hinge 410 and a second hinge 430. The first hinge 410 is disposed on the top wall of the cabinet body 500, and the second hinge 430 is disposed on the front of the cabinet body 500; the door body device includes a first cabinet door 111 and a second cabinet door 112. The top of the first cabinet door 111 is rotatably connected to the cabinet body 500 through the first hinge 410, and the bottom of the first cabinet door 111 and the top of the second cabinet door 112 are rotatably connected to the cabinet body 500 through the second hinge 430.

[0086] Exemplarily, the number of hinges 400 is at least two. The hinge 400 includes at least a first hinge 410 and a second hinge 430. Among them, the first hinge 410 is used for fixedly setting on the top wall of the cabinet body 500, the second hinge 430 is used for fixedly setting on the front of the cabinet body 500, and both the first hinge 410 and the second hinge 430 can be used for connecting the cabinet door 110.

[0087] The door body device includes two door body components 100, namely the first door body component and the second door body component. The first door body component includes a first box door 111, and the second door body component includes a second box door 112. As Figure 3 shown, the first box door 111 and the second box door 112 are spaced apart in the height direction of the box body 500.

[0088] The top of the first box door 111 can be rotatably connected to the box body 500 through a first hinge 410, the bottom of the first box door 111 can be rotatably connected to the box body 500 through a second hinge 430, and the top of the second box door 112 can be rotatably connected to the box body 500 through the second hinge 430.

[0089] In practical applications, according to different refrigeration requirements, different numbers of storage spaces will be set in the box body 500 of different refrigeration devices. These storage spaces are spaced apart in the height direction of the box body 500. Some storage spaces are for refrigeration, and some storage spaces are for freezing. Correspondingly, in order to be able to close these storage spaces targeted, the number of box doors 110 can be multiple, and each box door 110 corresponds to at least one of the storage spaces.

[0090] For example, as Figure 3 shown, the box body 500 is provided with two storage spaces spaced apart in the vertical direction. These two storage spaces can be used for refrigeration and freezing respectively. The number of box doors 110 is two, namely the first box door 111 and the second box door 112. These two box doors 110 correspond one-to-one with the positions of the two storage spaces. At this time, the two storage spaces can be opened or closed independently through these two box doors 110.

[0091] For another example, the box body 500 can be provided with three storage spaces spaced apart in the vertical direction, namely the first space, the second space and the third space. The first space and the second space are for refrigeration, and the third space is for freezing. The number of box doors 110 is two, namely the first box door 111 and the second box door 112. Among them, the first box door 111 corresponds one-to-one with the positions of the first space and the second space at the same time, and the second box door 112 corresponds to the position of the third space. At this time, the first space and the second space can be opened or closed simultaneously by using the first box door 111, and the opening and closing state of the third space can be controlled independently by using the second box door 112.

[0092] It can be understood that in this embodiment, each box door 110 can correspond to a single storage space. At this time, the box door 110 can independently control the opening and closing state of the storage space. Or, according to requirements, each box door 110 can also correspond to multiple adjacent storage spaces. At this time, the box door 110 can simultaneously control the opening and closing states of the multiple storage spaces.

[0093] Further, in one embodiment, as Figure 5 shown, the first hinge 410 includes a first hinge plate 411 and a first hinge shaft 412. A part of the first hinge plate 411 covers the top wall of the box body 500 and the remaining part protrudes from the top wall towards the box door 110. The first hinge shaft 412 extends downward from the part of the first hinge plate 411 protruding from the top wall. The top of the first box door 111 is hinged to the first hinge shaft 412, and the first traction assembly 310 is disposed on one of the first hinge plate 411 and the first hinge shaft 412.

[0094] Exemplarily, the first hinge plate 411 and the first hinge shaft 412 can be made of a metal or non-metal material with a certain structural strength. The first hinge plate 411 includes a first fitting portion and a first protruding portion connected to each other. The first fitting portion is provided with a plurality of mounting holes, and the first hinge shaft 412 is fixedly arranged on the first protruding portion by means of welding or threaded connection.

[0095] During actual installation, a plurality of threaded holes can be provided in advance on the top wall of the box body 500. Then, the first fitting portion of the first hinge plate 411 is fitted to the top wall of the box body 500, and at the same time, the mounting holes on the first fitting portion are aligned with the threaded holes. Then, the first fitting portion is fixed to the top wall of the box body 500 by means of bolts. At this time, the first fitting portion can cover and fit to the top wall of the box body 500, the first protruding portion can protrude from the top wall towards the first box door 111, and moreover, the first hinge shaft 412 can extend downward along the height direction of the box body 500.

[0096] Based on this, when installing the box door 110, a hinge hole can be provided in advance on the top of the first box door 111, and then the first hinge shaft 412 is inserted into the hinge hole, thereby realizing the installation of the first box door 111.

[0097] Moreover, a sliding door mechanism 300 is connected to the top of the first box door 111, and the traction assembly 310 in the sliding door mechanism 300 can be disposed on the first hinge plate 411 or on the first hinge shaft 412.

[0098] For example, as Figure 5 shown, in one embodiment, a vertical plate 413 is provided on the first hinge plate 411. The vertical plate 413 extends downward along the thickness direction of the first hinge plate 411, and the vertical plate 413 is provided with mounting holes.

[0099] As Figure 8 shown, during actual installation, the first hinge plate 411 is fixed to the top wall of the box body 500, the first box door 111 is rotatably connected to the first hinge shaft 412, and a part of the structure of the traction assembly 310 can be connected to the vertical plate 413 by means of bolts.

[0100] Further, in one embodiment, as Figure 6 shown, the second hinge 430 includes a second hinge plate 431, a second hinge shaft 432, and a third hinge shaft 433. The second hinge plate 431 includes a mounting plate 4311 and a connecting plate 4312. The mounting plate 4311 is mounted on the front surface of the box body 500. The connecting plate 4312 is connected to the side of the mounting plate 4311 facing away from the front surface of the box body 500. The connecting plate 4312 is disposed at an angle to the mounting plate 4311. The connecting plate 4312 has opposite first and second sides. The second hinge shaft 432 is disposed on the first side, and the bottom of the first door 111 is hinged to the second hinge shaft 432. The third hinge shaft 433 is disposed on the second side, and the top of the second door 112 is hinged to the third hinge shaft 433;

[0101] Wherein, the second traction assembly 310 and the third traction assembly 310 are both disposed on one of the mounting plate 4311 and the connecting plate 4312, or are respectively disposed on the second hinge shaft 432 and the third hinge shaft 433; or, the second traction assembly 310 is disposed on one of the mounting plate 4311 and the connecting plate 4312, and the third traction assembly 310 is disposed on one of the second hinge shaft 432 and the third hinge shaft 433.

[0102] Exemplarily, the second hinge plate 431, the second hinge shaft 432, and the third hinge shaft 433 can be made of a metal material or a non-metal material with a certain structural strength. The second hinge plate 431 includes a mounting plate 4311 and a connecting plate 4312 connected to each other. The connecting plate 4312 is substantially perpendicular to the mounting plate 4311. A plurality of mounting holes are provided on the mounting plate 4311. During actual production and manufacturing, the mounting plate 4311 and the connecting plate 4312 can be integrally formed on the same plate, and then, the connecting plate 4312 can be bent relative to the mounting plate 4311 by means of stamping and folding.

[0103] The two sides in the thickness direction of the connecting plate 4312 are respectively the first side and the second side. The second hinge shaft 432 is fixedly connected to the first side, and the third hinge shaft 433 is fixedly connected to the second side.

[0104] During actual production and manufacturing, the second hinge shaft 432 and the third hinge shaft 433 can be respectively fixedly connected to the connecting plate 4312 by welding. Alternatively, the second hinge shaft 432 and the third hinge shaft 433 can be configured as an integral piece in the shape of a long bar. The connecting plate 4312 is provided with through holes penetrating along its thickness direction. The integral piece is inserted into the through holes, and the integral piece is fixed in the through holes by welding or threaded connection. The two ends of the integral piece in the length direction on the connecting plate 4312 are respectively formed as the second hinge shaft 432 and the third hinge shaft 433.

[0105] During actual installation, as Figure 9As shown, multiple threaded holes can be set in advance on the front of the box body 500 according to the installation position of the box door 110. For example, as Figure 3 shown, multiple threaded holes are set at the position corresponding to the gap between the first box door 111 and the second box door 112 on the front of the box body 500. Then, the mounting holes on the mounting plate 4311 of the second hinge plate 431 are aligned with the positions of the threaded holes, and then the mounting plate 4311 is fixed to the front of the box body 500 by means of bolts. At this time, the connecting plate 4312 extends towards the direction of the box door 110. At the same time, the second hinge shaft 432 extends upward along the height direction of the box body 500, and the third hinge shaft 433 extends downward along the height direction of the box body 500.

[0106] Based on this, when installing the box door 110, hinge holes can be set in advance at the bottom of the first box door 111, and hinge holes can be set in advance at the top of the second box door 112. Then, the second hinge shaft 432 can be inserted into the hinge hole at the bottom of the first box door 111, and the third hinge shaft 433 can be inserted into the hinge hole at the top of the second box door 112. Thus, the installation of the first box door 111 and the second box door 112 can be realized.

[0107] In addition, a sliding door mechanism 300 is connected to the bottom of the first box door 111. The traction assembly 310 in the sliding door mechanism 300 can be set on the mounting plate 4311 or the connecting plate 4312, or can also be set on the second hinge shaft 432. A sliding door mechanism 300 is connected to the top of the second box door 112. The traction assembly 310 in the sliding door mechanism 300 can be set on the mounting plate 4311 or the connecting plate 4312, or can also be set on the third hinge shaft 433. It can be understood that according to actual installation requirements, the two traction assemblies 310 can be set on the same structure or on different structures.

[0108] For example, as Figure 9 shown, the first box door 111 and the second box door 112 are respectively connected with a sliding door mechanism 300. The traction assemblies 310 in the two sliding door mechanisms 300 can be fixedly connected to the mounting plate 4311 via the same bolt.

[0109] Furthermore, in one embodiment, the central axis of the second hinge shaft 432 and the central axis of the third hinge shaft 433 are coaxially arranged.

[0110] It can be understood that by setting the central axis of the second hinge shaft 432 and the central axis of the third hinge shaft 433 to be collinear, the first box door 111 and the second box door 112 can be rotated around the same rotation axis, so that the connection structure between the box door 110 and the box body 500 is more reasonable and more convenient for installation.

[0111] Furthermore, in one embodiment, asFigure 3 and Figure 7 As shown in Figure 7 , the hinge 400 further includes a third hinge 420, which includes a third hinge plate 421 and a fourth hinge shaft 422. The third hinge plate 421 includes a support plate 4211 and an extension plate 4212. The support plate 4211 is installed on the front surface of the box body 500. The extension plate 4212 is connected to one side of the support plate 4211 facing away from the front surface of the box body 500. The support plate 4211 and the extension plate 4212 are arranged at an angle. The fourth hinge shaft 422 is arranged on the top surface of the extension plate 4212 and extends upward. The bottom of the second door 112 is hinged to the fourth hinge shaft 422.

[0112] Exemplarily, the third hinge plate 421 and the fourth hinge shaft 422 can also be made of metal or non-metal materials with a certain structural strength. The third hinge plate 421 includes a support plate 4211 and an extension plate 4212 that are connected to each other. The extension plate 4212 is substantially perpendicular to the support plate 4211. The two can be integrally formed by stamping or other methods. The support plate 4211 is provided with a plurality of mounting holes. The fourth hinge shaft 422 is fixedly arranged on the extension plate 4212 by welding or threaded connection or other methods.

[0113] During actual installation, a plurality of threaded holes can be set in advance at a position on the front surface of the box body 500 and close to the bottom. Then, let one side of the support plate 4211 in the thickness direction fit to the front surface of the box body 500, and make the mounting holes on the support plate 4211 correspond to the positions of the threaded holes. Then, fix the support plate 4211 to the front surface of the box body 500 with bolts. The extension plate 4212 is connected to the other side of the support plate 4211 in the thickness direction and extends towards the direction where the second door 112 is located. Moreover, the fourth hinge shaft 422 extends upward along the height direction of the box body 500.

[0114] Based on this, when installing the door 110, an articulation hole can be set in advance at the bottom of the second door 112. Then, insert the fourth hinge shaft 422 into the articulation hole. Thus, the installation of the second door 112 can be achieved.

[0115] In a specific embodiment, as Figure 3 shown, two storage spaces are arranged at intervals along the height direction of the box body 500. A first hinge 410 is arranged at the top of the box body 500. A second hinge 430 is arranged at a position in the middle of the box body 500 and approximately between the two storage spaces. A third hinge 420 is arranged at the bottom of the box body 500. The door device includes two door assemblies 100. The two door assemblies 100 respectively include a first door 111 and a second door 112. The first door 111 and the second door 112 are arranged at intervals along the height direction of the box body 500. The first door 111 and the second door 112 respectively correspond to the two storage spaces of the box body 500.

[0116] During installation, the top of the first cabinet door 111 is hinged to the first hinge axis 412 of the first hinge 410, and the bottom of the first cabinet door 111 is hinged to the second hinge axis 432 of the second hinge 430. The top of the second cabinet door 112 is hinged to the third hinge axis 433 of the second hinge 430, and the bottom of the second cabinet door 112 is hinged to the fourth hinge axis 422 of the third hinge 420.

[0117] Thus, through the above-described setting method, the first cabinet door 111 and the second cabinet door 112 can be rotatably connected to the cabinet body 500.

[0118] Further, in one embodiment, as Figure 10 shown, in order to ensure that the traction assembly 310 can drive the sliding door assembly 320 to move, the hinge 400 includes a hinge plate and a hinge axis provided on the hinge plate. The hinge plate is provided on the cabinet body 500, and the bottom of the cabinet door 110 is rotatably provided on the cabinet body 500 through the hinge axis. The traction assembly 310 includes a traction rod 311, a first rotating shaft fixing seat 312, and a second rotating shaft fixing seat 313. The first rotating shaft fixing seat 312 is connected to the sliding door assembly 320, and the second rotating shaft fixing seat 313 is connected to the hinge plate. One end of the traction rod 311 is rotatably connected to the first rotating shaft fixing seat 312, and the other end of the traction rod 311 is rotatably connected to the second rotating shaft fixing seat 313. During the opening or closing process of the cabinet door 110, the traction rod 311 drives the sliding door assembly 320 to act, thereby driving the cabinet door 200 to move relative to the width direction of the cabinet door 110.

[0119] Exemplarily, the hinge 400 may include a hinge plate and a hinge axis, and the hinge axis is fixedly provided on the hinge plate by means of welding or the like. During actual installation, the hinge plate can be fixedly provided on the cabinet body 500 by means of structures such as bolts. Threaded holes can be provided in the cabinet door 110 in advance. After the hinge plate is fixed to the cabinet body 500, the hinge axis can be inserted into the hinge hole of the cabinet door 110, so as to realize the rotational connection of the cabinet door 110 relative to the cabinet body 500.

[0120] In the traction assembly 310, the first rotating shaft fixing seat 312 is provided on the sliding door assembly 320, the second rotating shaft fixing seat 313 is provided on the hinge plate, and both ends of the traction rod 311 are respectively rotatably connected to the first rotating shaft fixing seat 312 and the second rotating shaft fixing seat 313.

[0121] During actual use, when the cabinet door 110 rotates between the positions of opening or closing the storage space relative to the cabinet body 500, the traction assembly 310 can pull the sliding door assembly 320 to act, so that the sliding door assembly 320 drives the cabinet door 200 to move relative to the cabinet door 110 in the width direction of the cabinet door 110.

[0122] Further, in one embodiment, in order to enable the sliding door assembly 320 to effectively drive the cabinet door 200 to move relative to the box door 110 under the drive of the traction assembly 310, as Figure 10 and Figure 11 shown, the sliding door assembly 320 includes: a base 321, a first slider 322, a second slider 323, a guide member 330, and a connecting member 324.

[0123] Among them, a first guide rail 3211 is formed on one side of the base 321, and a second guide rail 3212 is formed on the other side; the first slider 322 is slidably disposed on the first guide rail 3211, and the first rotating shaft fixing seat 312 is connected to the first slider 322; the second slider 323 is slidably disposed on the second guide rail 3212 and is connected to the cabinet door 200; the guide member 330 is disposed on the base 321, the connecting member 324 is wound around the guide member 330, and two ends of the connecting member 324 are respectively connected to the first slider 322 and the second slider 323; during the opening or closing process of the box door 110, the traction rod 311 drives the first slider 322 to move on the first guide rail 3211, and the first slider 322 drives the second slider 323 to move in the opposite direction on the second guide rail 3212 through the connecting member 324.

[0124] Specifically, as Figure 10 and Figure 11 shown, the first guide rail 3211 is located at the top of the base 321 and provides a sliding track for the first slider 322. The second guide rail 3212 is located at the bottom of the base 321, parallel or at a certain angle to the first guide rail 3211, and provides a sliding track for the second slider 323. The first slider 322 is slidably disposed on the first guide rail 3211 for transmission connection with the box body 500. The second slider 323 is slidably disposed on the second guide rail 3212 for connection with the cabinet door 200. The connecting member 324 can be a connecting component such as a traction rope or a transmission belt. The connecting member 324 is wound around the guide member 330, and two ends of the connecting member 324 are respectively connected to the first slider 322 and the second slider 323.

[0125] When the first slider 322 is driven to move on the first guide rail 3211 by a driving force, since two ends of the connecting member 324 are respectively fixed to the first slider 322 and the second slider 323, and the connecting member 324 is wound around the guide member 330, by reasonably setting the extending direction of the connecting member 324, the connecting member 324 will drive the second slider 323 to move in the opposite direction on the second guide rail 3212. This characteristic of synchronous reverse movement enables the cabinet door 200 to slide in the width direction of the box body 500 when the first slider 322 is in transmission connection with the box body 500 and the second slider 323 is connected to the cabinet door 200.

[0126] Further, in one embodiment, as Figure 10 andFigure 11 As shown, the connecting member 324 is a rope, and the guiding member 330 is a support shaft; the support shaft is connected to the base 321 and is located between the first guide rail 3211 and the second guide rail 3212. The rope is wound around the support shaft, and the two ends of the rope are respectively connected to the first slider 322 and the second slider 323.

[0127] In this embodiment, the guiding member 330 is specifically embodied as a support shaft. The support shaft is firmly connected to the base 321 and is generally located at the central position between the first guide rail 3211 and the second guide rail 3212 (the actual position can be adjusted according to design requirements). The main function of the support shaft is to provide a stable fulcrum for the rope to wind around, thereby guiding the movement direction of the rope and ensuring that the first slider 322 and the second slider 323 can move synchronously and in opposite directions along a predetermined trajectory. The two ends of the rope are respectively connected to the first slider 322 and the second slider 323. As a flexible but strong connecting material, the rope is very suitable for transmitting the movement and force between the two sliders. The rope is wound around the support shaft. This winding method enables the rope to slide along the support shaft and stretch or contract accordingly when the first slider 322 moves on the first guide rail 3211, thereby driving the second slider 323 to move in the opposite direction on the second guide rail 3212. The winding method of the rope may adopt a single loop, multiple loops or other complex winding patterns according to actual needs to achieve the best transmission effect. At the same time, fixing points or clamps for connecting the rope are respectively provided on the first slider 322 and the second slider 323. These fixing points or clamps should be designed to be strong enough to withstand the tensile force and shear force transmitted by the rope to ensure the stable movement of the slider.

[0128] Furthermore, in one embodiment, as Figure 10 and Figure 11 shown, there are two ropes, namely the first rope and the second rope; there are two support shafts, namely the first support shaft and the second support shaft; the first support shaft is connected to one side of the base 321, the second support shaft is connected to the other side of the base 321, the first rope is wound around the first support shaft, and the two ends of the first rope are respectively connected to one side of the first slider 322 and one side of the second slider 323. The second rope is wound around the second support shaft, and the two ends of the second rope are respectively connected to the other side of the first slider 322 and the other side of the second slider 323.

[0129] When the first slider 322 moves on the first guide rail 3211, it will pull the second slider 323 to move in the opposite direction on the second guide rail 3212 through the first rope. Similarly, the two ends of the second rope are respectively connected to the other side of the first slider 322 and the other side of the second slider 323, providing another independent path for the reverse movement between the two.

[0130] Since the two ropes are respectively wound around two support shafts and independently connect the two sides of the first slider 322 and the second slider 323, they can transmit force and motion more evenly. This design helps to improve the problem of asynchronous movement of the sliders caused by uneven rope tension or deviation of the support shaft position.

[0131] In some embodiments, as Figure 10 and Figure 11 shown, when using a single rope to connect the first slider 322 and the second slider 323, according to the position of the support shaft setting, after the first slider 322 moves a certain distance on the first guide rail 3211, the second slider 323 will only move a short distance, and the two will not move synchronously throughout the process.

[0132] To ensure that the first slider 322 and the second slider 323 can move synchronously throughout the process when moving in opposite directions, as Figure 10 and Figure 11 shown, one end of the first rope is connected to the front end of one side of the first slider 322, the other end of the first rope is connected to the front end of one side of the second slider 323, one end of the second rope is connected to the rear end of the other side of the first slider 322, and the other end of the second rope is connected to the rear end of the other side of the second slider 323.

[0133] Specifically, in this embodiment, as Figure 10 and Figure 11 shown, the first rope is wound around the first support shaft on the front side of the base 321. One end of the first rope is connected to a position slightly to the left of the front side of the first slider 322, and the other end of the first rope is connected to a position slightly to the left of the front side of the second slider 323. Correspondingly, the second rope is wound around the second support shaft on the rear side of the base 321. One end of the second rope is connected to a position slightly to the right of the rear side of the first slider 322, and the other end of the second rope is connected to a position slightly to the right of the rear side of the second slider 323.

[0134] Through the above connection method, as Figure 10 and Figure 11 shown, when the first slider 322 moves to the right on the first guide rail 3211, although the first rope is difficult to pull the second slider 323 to move, the second rope can pull the second slider 323 to move in the opposite direction (to the left) on the second guide rail 3212. When the first slider 322 moves to the left, the first rope can pull the second slider 323 to move in the opposite direction (to the right).

[0135] During actual installation, after the hinge plate is fixedly installed on the box body 500, the second rotating shaft fixing seat 313 can be fixed on the hinge plate by means of structures such as bolts. Exemplarily, a through hole is provided in the second rotating shaft fixing seat 313. During installation, an external bolt can be passed through the through hole and connected to the hinge plate, thereby fixing the second rotating shaft fixing seat 313 on the hinge plate.

[0136] Next, the base 321 can be fixed on the door 110 by means of structures such as bolts. Exemplarily, engaging plates 325 are respectively provided on both sides in the length direction of the base 321, and through holes are respectively provided on the two engaging plates 325. During installation, an external bolt can be passed through the through holes on the two engaging plates 325 and connected to the door 110, thereby fixing the base 321 on the door 110.

[0137] After that, the cabinet door 200 is fixed to the second slider 323. For example, the cabinet door 200 can be fixedly connected to the second slider 323 by means of bolts or snap - connection structures, etc.

[0138] During actual use, as Figure 10 and Figure 11 shown, when the door 110 moves relative to the box body 500 from the position of closing the storage space towards the position of opening the storage space, since the first rotating shaft fixing seat 312 is fixed to the door 110 following the hinge seat, during the rotation of the door 110, the first slider 322 will move along the A direction on the first guide rail 3211. Correspondingly, the first slider 322 will pull the second slider 323 to move along the B direction on the second guide rail 3212 through the first connecting member 3241. Since the base 321 is fixedly connected to the door 110 and the second slider 323 is fixedly connected to the cabinet door 200, at this time, the cabinet door 200 will move along the B direction relative to the door 110. Wherein, the A direction is opposite to the B direction, and both the A direction and the B direction are parallel to the width direction of the door 110.

[0139] Correspondingly, when the door 110 moves relative to the box body 500 from the position of opening the storage space towards the position of closing the storage space, during the rotation of the door 110, the first slider 322 will move along the direction opposite to the A direction on the first guide rail 3211. Correspondingly, the first slider 322 will pull the second slider 323 to move along the direction opposite to the B direction on the second guide rail 3212 through the second connecting member 3242. At this time, the cabinet door 200 will move along the direction opposite to the B direction relative to the door 110.

[0140] Furthermore, in yet another specific implementation manner, as Figures 12 to 14As shown, the base 321 is configured as a plate-like structure with a certain length. The first guide rail 3211 and the second guide rail 3212 are respectively arranged on both sides in the width direction of the base 321. Moreover, both the first guide rail 3211 and the second guide rail 3212 extend along the length direction of the base 321. The first slider 322 is slidably arranged on the first guide rail 3211, and the second slider 323 is slidably arranged on the second guide rail 3212.

[0141] In some embodiments, the traction assembly includes: a first link and a second link. The first end of the first link is rotatably arranged on the hinge 400. For example, it is arranged on the hinge plate of the hinge 400.

[0142] Among them, the first end of the first link is rotatably arranged in the installation area. For example, the first end of the first link is installed in the installation area through a rotating shaft fixing seat. The first end of the second link is rotatably connected to the second end of the first link; the second end of the second link is rotatably arranged on the cabinet door 110 and is meshed and connected to the tooth part on the first slider 322 through the gear arranged at the second end of the second link.

[0143] It can be understood that the first link and the second link are connected by a hinge, and the first link and the second link can rotate relative to each other. The first link can rotate relative to the box body 500, and the second link can rotate relative to the cabinet door 110.

[0144] When the second end of the second link makes a circular motion around the hinge axis with the cabinet door 110 as the center, since the first end of the first link is arranged in a staggered manner with the hinge axis, the distance between the second end of the second link and the first end of the first link changes, while the position of the second end of the second link relative to the cabinet door 110 remains unchanged. As a result, the second end of the second link rotates around the cabinet door 110 and drives the second slider 323 to drive the cabinet door 200 to move along the width direction of the cabinet door 110.

[0145] In actual application, during the opening process of the door 110, the door 110 drives the second end of the second connecting rod to rotate relative to the hinge axis. Based on the staggered arrangement of the first end of the first connecting rod and the hinge axis, the distance between the first end of the first connecting rod and the second end of the second connecting rod increases, driving the second end of the second connecting rod to rotate clockwise relative to the door 110, thereby controlling the second slider 323 to drive the cabinet door 200 to move along the width direction of the door 110 in the direction away from the hinge 400, that is, to move to the left relative to the door 110, so as to avoid interference between the cabinet door 200 and the cabinet door 200 of the side cabinet; During the closing process of the door 110, the second end of the second connecting rod is driven to rotate relative to the hinge axis. Based on the staggered arrangement of the first end of the first connecting rod and the hinge axis, the distance between the first end of the first connecting rod and the second end of the second connecting rod is reduced, driving the second end of the second connecting rod to rotate counterclockwise relative to the door 110, thereby controlling the second slider 323 to drive the cabinet door 200 to move along the width direction of the door 110 toward the direction close to the hinge 400, that is, to move to the right side relative to the door 110. This ensures that when the door 110 is closed, the cabinet door 200 can avoid the cabinet door 200 of the cabinet on the side and reset the cabinet door 200.

[0146] In an optional embodiment, the first rotating shaft fixing seat 312 is connected to the first slider 322, and the cabinet door 200 can be fixedly connected to the second slider 323. The first guide rail and the second guide rail are a kind of track, and the first slider 322 and the second slider 323 are sliding members adapted to the corresponding guide rail and can slide along the corresponding guide rail; in addition, the sliding cooperation between the first slider 322 and the first guide rail should at least include the situation that a ball is arranged between the first slider 322 and the first guide rail, and the sliding cooperation between the second slider 323 and the second guide rail should at least include the situation that a ball is arranged between the second slider 323 and the second guide rail.

[0147] Accordingly, the traction rod 311 may be constructed as an arc-shaped rod, one end of the traction rod 311 is rotatably connected to the first rotation shaft fixing seat 312 via a first rotation shaft, and the other end of the traction rod 311 is rotatably connected to the second rotation shaft fixing seat 313 via a second rotation shaft.

[0148] As a way to achieve this, Figure 13 and Figure 14 As shown, the first rotating shaft fixing seat 312 is provided with a first clamping portion, and the first clamping portion includes two clamping plates arranged side by side and spaced apart, and the two clamping plates are respectively provided with pin holes, and the first rotating shaft is inserted into the two pin holes at the same time, and one end of the traction rod 311 can be placed between the two clamping plates, and the end of the traction rod 311 is rotatably connected to the first rotating shaft, thereby, the traction rod 311 can be rotatably connected to the first rotating shaft fixing seat 312. Moreover, the first rotating shaft fixing seat 312 can be fixedly connected to the first sliding block 322 by welding or the like.

[0149] Similarly, as Figure 12 and Figure 14 shown, a second rotating shaft fixing seat 313 is provided with a second clamping portion, which also includes two clamping plates arranged side by side at intervals. The two clamping plates are respectively provided with pin holes, and the second rotating shaft is inserted into the two pin holes at the same time. The other end of the traction rod 311 can be placed between the two clamping plates, and the end of the traction rod 311 is rotatably connected to the second rotating shaft. Thus, the traction rod 311 can be rotatably connected to the second rotating shaft fixing seat 313.

[0150] The first slider 322 and the second slider 323 are connected to each other through a connecting member 324. During the movement of the first slider 322, the second slider 323 can be driven to move in the opposite direction by means of the connecting member 324.

[0151] During actual installation, after the hinge plate is fixedly installed on the box body 500, the second rotating shaft fixing seat 313 can be fixed on the hinge plate by means of structures such as bolts. Exemplarily, a through hole is provided in the second rotating shaft fixing seat 313. During installation, an external bolt can be passed through the through hole and connected to the hinge plate, so as to fix the second rotating shaft fixing seat 313 on the hinge plate.

[0152] Then, the base 321 can be fixed on the cabinet door 110 by means of structures such as bolts. Exemplarily, a first receiving plate 326 and a second receiving plate 327 are respectively provided on both sides in the length direction of the base 321, and through holes are respectively provided on the first receiving plate 326 and the second receiving plate 327. During installation, an external bolt can be passed through the through holes on the first receiving plate 326 and the second receiving plate 327 and connected to the cabinet door 110, so as to fix the base 321 on the cabinet door 110.

[0153] After that, the cabinet door 200 is fixed to the second slider 323. For example, the cabinet door 200 can be fixedly connected to the second slider 323 by means of bolts or clamping structures.

[0154] During actual use, as Figure 12 and Figure 13As shown, when the door 110 moves relative to the box body 500 from the position of closing the storage space towards the position of opening the storage space, since the first rotating shaft fixing seat 312 is fixed to the door 110 following the hinge seat, during the rotation of the door 110, the first slider 322 will move along the C direction on the first guide rail 3211. Correspondingly, the first slider 322 will pull the second slider 323 to move along the D direction on the second guide rail 3212 through the connecting member 324. Since the base 321 is fixedly connected to the door 110 and the second slider 323 is fixedly connected to the cabinet door 200, at this time, the cabinet door 200 will move relative to the door 110 along the D direction. Wherein, the C direction is opposite to the D direction, and both the C direction and the D direction are parallel to the width direction of the door 110.

[0155] Correspondingly, when the door 110 moves relative to the box body 500 from the position of opening the storage space towards the position of closing the storage space, during the rotation of the door 110, the first slider 322 will move along the direction opposite to the C direction on the first guide rail 3211. Correspondingly, the first slider 322 will pull the second slider 323 to move along the direction opposite to the D direction on the second guide rail 3212 through the connecting member 324. At this time, the cabinet door 200 will move relative to the door 110 along the direction opposite to the D direction.

[0156] Furthermore, in one embodiment, in order to ensure that the first slider 322 can effectively drive the second slider 323 to move in the reverse direction, as Figures 12 to 14 shown, the connecting member 324 includes: a first connecting member 3241 and a second connecting member 3242.

[0157] Wherein, the first connecting member 3241 bypasses one end of the base 321, and both ends are respectively connected to one end of the first slider 322 and the second slider 323; the second connecting member 3242 bypasses the other end of the base 321, and both ends are respectively connected to the other end of the first slider 322 and the second slider 323.

[0158] Exemplarily, the first connecting member 3241 can be a flexible rope. In the length direction of the base 321, one end of the first connecting member 3241 is connected to the first slider 322, and the other end is connected to the second slider 323 after bypassing one end of the base 321. That is, in the length direction of the base 321, the first connecting member 3241 bypasses one end of the base 321, and both ends thereof extend towards the first slider 322 and the second slider 323 respectively, and are respectively connected to the first slider 322 and the second slider 323.

[0159] Correspondingly, one end of the second connecting member 3242 is connected to the first slider 322, and the other end is connected to the second slider 323 after bypassing the other end of the base 321. That is, in the length direction of the base 321, the second connecting member 3242 bypasses the other end of the base 321, and its two ends are also respectively connected to the first slider 322 and the second slider 323.

[0160] At this time, the two ends of the first connecting member 3241 are respectively connected to the two ends of the second connecting member 3242 via the first slider 322 and the second slider 323, and form a substantially annular structure.

[0161] Exemplarily, in order to ensure that the first connecting member 3241 and the second connecting member 3242 can normally pull the second slider 323 to move, as Figure 14 shown, a first roller 328 and a second roller 329 are respectively arranged on both sides in the length direction of the base 321. The first roller 328 and the second roller 329 can respectively support the first connecting member 3241 and the second connecting member 3242.

[0162] Specifically, as Figure 14 shown, the number of the first rollers 328 is two. The two first rollers 328 are arranged at intervals in the width direction of the base 321. Moreover, the two first rollers 328 can be respectively rotatably arranged on the first receiving plate 326. In order to facilitate receiving the first connecting member 3241, a receiving groove can be arranged on the outer periphery of the first roller 328 along its circumferential direction. Thus, when installing the first connecting member 3241, the first connecting member 3241 can be placed in the receiving grooves of the two first rollers 328. Thereafter, when the first slider 322 pulls the second slider 323 by means of the first connecting member 3241, the first connecting member 3241 can drive the two first rollers 328 to rotate.

[0163] Similarly, the number of the second rollers 329 is two. The two second rollers 329 are arranged at intervals in the width direction of the base 321. Moreover, the two second rollers 329 can be respectively rotatably arranged on the second receiving plate 327. In order to facilitate receiving the second connecting member 3242, a receiving groove can also be arranged on the outer periphery of the second roller 329 along its circumferential direction. Thus, when installing the second connecting member 3242, the second connecting member 3242 can be placed in the receiving grooves of the two second rollers 329. Thereafter, when the first slider 322 pulls the second slider 323 by means of the second connecting member 3242, the second connecting member 3242 can drive the two second rollers 329 to rotate.

[0164] Thus, in the above setting method, the first roller 328 can support and limit the first connecting member 3241, and the second roller 329 can support and limit the second connecting member 3242. By means of the first roller 328 and the second roller 329, it can be avoided that the first connecting member 3241 and the second connecting member 3242 contact other components during the movement process, resulting in wear and consumption, and an effective protection effect can be achieved on the first connecting member 3241 and the second connecting member 3242.

[0165] In addition, as described above, a refrigeration device is also provided in this embodiment. The refrigeration device includes a box body 500 and the door device described in the above embodiment. Among them, the box body 500 forms a storage space, and the box door 110 is rotatably connected to the box body 500 through a hinge 400 and is adapted to open or close the storage space of the box body 500.

[0166] Finally, it should be noted that: the parallelism and perpendicularity referred to in the embodiments of the present invention should not be strictly limited in the geometric sense. At least the manufacturing and installation errors should be considered. For example, errors of plus or minus 10° should be within the scope protected by the embodiments of the present invention.
