That is to say, each door body assembly 10 is correspondingly provided with a sliding door mechanism 300, and the multiple traction components 310 corresponding to the multiple door body assemblies 10 are respectively located at different positions on the front surface of the box body 500.

[0060] 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 arranged in the box body 500 of the refrigeration device, and the refrigeration device can perform refrigeration processing on the storage space.

[0061] In this embodiment, the box door 100 in the door body device is rotatably arranged on the box body 500 of the refrigeration device through a hinge 400. The box door 100 can be used to open or close the storage space in the box body 500. When the box door 100 is in the closed position of closing the storage space, the storage space is in a closed state, and the items in the storage space can be refrigerated. When the box door 100 is in the open position of opening the storage space, the storage space is in an open state, and the user can take out the items in the storage space.

[0062] For the convenience of expressing the positional relationship between various components, in this embodiment, as Figure 2As shown, the cabinet 500 is generally constructed as a cuboid structure with a certain height. The cabinet 500 can be placed on a horizontal plane. The cabinet 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 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.

[0063] A storage space is provided inside the cabinet 500. An opening is provided on the side of the cabinet 500 in the thickness direction. The opening communicates with the storage space. The door 100 is connected to the side of the cabinet 500 in the thickness direction where the opening is provided. The door 100 extends along the width direction of the cabinet 500. A hinge 400 is connected to one side of the door 100 in the width direction of the cabinet 500. The door 100 can be rotatably connected to the cabinet 500 via the hinge 400, so as to ensure that the door 100 can open or close the storage space of the cabinet 500. Moreover, the side of the cabinet 500 where the door 100 is installed is the front, that is, the door 100 is installed on the front of the cabinet 500.

[0064] The door 100 is generally constructed as a flat plate-like structure with a certain thickness. The door 100 has a height direction, a width direction, and a thickness direction that are perpendicular to each other. Among them, the height direction of the door 100 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 door 100 in the width direction can be rotatably connected to the cabinet 500 via the hinge 400. For example, as Figure 2 shown, the door 100 is connected to the hinge 400 on the right side of the cabinet 500 in the width direction. The door 100 can be rotatably connected to the cabinet 500 via the hinge 400.

[0065] Moreover, when the door 100 is in the position of closing the storage space of the cabinet 500, the width direction of the door 100 is parallel to the width direction of the cabinet 500, and the thickness direction of the door 100 is parallel to the thickness direction of the cabinet 500.

[0066] 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 door 100 facing away from the cabinet 500. When the refrigeration device is placed together with the cabinet in an embedded manner or directly placed in the cabinet, after the door 100 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 door 100 can be flush with the outer wall surface of the cabinet.

[0067] 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, so that the refrigeration device can have sufficient coordination with the cabinet and ensure the aesthetics.

[0068] In one embodiment, as Figure 1 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 100, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the box door 100, so that the cabinet door 200 avoids the side walls of the first cabinet body 510 and the second cabinet body 520;

[0069] 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 100, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the box door 100, so that the cabinet door 200 avoids the side walls of the cabinet body.

[0070] It can be understood that the refrigeration device includes the door body device and the box body 500.

[0071] In practice, as Figure 1 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, a cabinet door 200 can be arranged on the outer side of the box door 100 in the door body device, and the cabinet door 200 can move relative to the box door 100 along the width direction of the box door 100. Optionally, when the box door 100 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 100 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 100 are in the same direction in the thickness direction of the box body 500.

[0072] At this time, during the process of the box door 100 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.

[0073] Alternatively, after the refrigeration device is placed in the cabinet body, a cabinet door 200 can be arranged on the outer side of the box door 100 of the door body device, and the cabinet door 200 can move relative to the box door 100. Optionally, when the box door 100 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 100 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 100 are in the same direction in the thickness direction of the box body 500.

[0074] At this time, during the process of the box door 100 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.

[0075] Therefore, after the door device in this embodiment is installed on the cabinet 500 of the refrigeration device, during the rotation of the cabinet door 100 relative to the cabinet 500, the sliding door assembly 320 can drive the cabinet door 200 to move relative to the cabinet door 100 under the drive of the traction assembly 310. Thus, when the refrigeration device is placed in the cabinet in an embedded manner, without affecting the user experience and ensuring coordination and aesthetics, interference between the cabinet door 200 and the cabinet can be avoided during the opening of the cabinet door 100.

[0076] In a specific embodiment, as Figure 2 shown, the door device includes a first cabinet door 110 and a second cabinet door 120. The first cabinet door 110 and the second cabinet door 120 are arranged at intervals along the height direction of the cabinet 500. At this time, the top of the first cabinet door 110 can be rotatably connected to the cabinet 500 by means of a first hinge 410, and the bottom of the second cabinet door 120 can be rotatably connected to the cabinet 500 by means of a second hinge 420.

[0077] Correspondingly, as Figure 3 shown, the traction assembly 310 located on the upper crossbeam 501 of the cabinet 500 is arranged close to the first hinge 410. Under the action of the traction assembly 310, the sliding door assembly 320 can drive the cabinet door 200 corresponding to the first cabinet door 110 to move in the width direction of the first cabinet door 110.

[0078] As Figure 4 shown, the traction assembly 310 located on the lower crossbeam 502 of the cabinet 500 is arranged close to the second hinge 420. Under the action of the traction assembly 310, the sliding door assembly 320 can drive the cabinet door 200 corresponding to the second cabinet door 120 to move in the width direction of the second cabinet door 120.

[0079] Furthermore, in an 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 cabinet 500 and the rest protrudes from the top wall towards the corresponding cabinet door 100. The first hinge shaft 412 extends downward from the part of the first hinge plate 411 that protrudes from the top wall, and the top of the corresponding cabinet door 100 is hinged to the first hinge shaft 412.

[0080] Exemplarily, the first hinge plate 411 and the first hinge shaft 412 can be made of metal or non-metal materials with a certain structural strength. The first hinge plate 411 includes a first fitting part and a first protruding part that are connected to each other. The first fitting part is provided with a plurality of mounting holes, and the first hinge shaft 412 is fixedly arranged on the first protruding part by means of welding or threaded connection, etc.

[0081] 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 made to fit against the top wall of the box body 500. At the same time, the mounting holes on the first fitting portion are aligned with the positions of 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 against the top wall of the box body 500, the first protruding portion can protrude from the top wall towards the door 100, and moreover, the first hinge shaft 412 can extend downward along the height direction of the box body 500.

[0082] Based on this, when installing the door 100, a hinge hole can be provided in advance at the top of the door 100 corresponding to the first hinge 410. Then, the first hinge shaft 412 is inserted into the hinge hole, thereby enabling the installation of the door 100.

[0083] In this way, the traction assembly 310 on the upper cross beam 501 of the box body 500 is arranged close to the first hinge plate 411. In addition, as Figure 3 shown, the traction assembly 310 is arranged in the first installation area A. The first installation area A is located on the upper cross beam 501 of the box body 500. The first installation area A includes a first side, a second side, a third side, and a fourth side. The first side and the third side are arranged opposite to each other, the second side and the fourth side are arranged opposite to each other. The first side is located in the plane where the first hinge plate 411 is located, and the second side is located in the plane where the side surface of the box body 500 is located. In the height direction of the box body 500, a first distance is left between the third side and the first side; in the width direction of the box body 500, a second distance is left between the fourth side and the second side.

[0084] In an alternative embodiment, the first distance is greater than zero and less than or equal to 60 mm, and the second distance is greater than zero and less than or equal to 100 mm. For example, the second distance is 10 mm, 20 mm, 50 mm, 70 mm, 100 mm, and the first distance is 10 mm, 20 mm, 50 mm, 60 mm.

[0085] Furthermore, in one embodiment, as Figure 6 shown, the second hinge 420 includes a second hinge plate 421 and a second hinge shaft 422. The second hinge plate 421 includes a support plate 4211 and an extension plate 4212. The support plate 4211 is installed on the front surface (lower cross beam 502) of the box body 500. The extension plate 4212 is connected to the 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 second hinge shaft 422 is arranged on the top surface of the extension plate 4212 and extends upward. The bottom of the second door 120 is hinged to the second hinge shaft 422.

[0086] Similarly, the second hinge plate 421 and the second hinge shaft 422 can also be made of metal or non-metal materials with a certain structural strength. The second 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, and the two can be integrally formed by stamping or other means. The support plate 4211 is provided with a plurality of mounting holes, and the second hinge shaft 422 is fixedly arranged on the extension plate 4212 by means of welding or threaded connection.

[0087] During actual installation, a plurality of threaded holes can be provided in advance at a position on the front surface of the box body 500 and near the bottom. Then, one side in the thickness direction of the support plate 4211 is attached to the front surface of the box body 500. After that, the mounting holes on the support plate 4211 are aligned with the threaded holes, and then the support plate 4211 is fixed to the front surface of the box body 500 by means of bolts. The extension plate 4212 is connected to the other side in the thickness direction of the support plate 4211 and extends towards the direction where the box door 100 is located. Moreover, the second hinge shaft 422 extends upward along the height direction of the box body 500.

[0088] Based on this, when installing the box door 100, a hinge hole can be provided in advance at the bottom of the box door 100 corresponding to the second hinge 420. Then, the second hinge shaft 422 is inserted into the hinge hole, and thus, the installation of the box door 100 can be achieved.

[0089] In this way, the traction assembly 310 on the lower cross beam 502 of the box body 500 is arranged close to the second hinge plate 421. In addition, the traction assembly 310 is arranged in the second installation area B, and the second installation area B is located on the lower cross beam 502 of the box body 500. As Figure 4 shown, the second installation area B is located above the support plate 4211. The second installation area B includes a first side, a second side, a third side, and a fourth side. The first side and the third side are arranged opposite to each other, the second side and the fourth side are arranged opposite to each other. The first side is the top side of the support plate 4211, the second side is located in the plane where the side surface of the box body 500 is located. In the height direction of the box body 500, a third distance is left between the third side and the first side; in the width direction of the box body 500, a fourth distance is left between the fourth side and the second side.

[0090] In an alternative embodiment, the third distance is greater than zero and less than or equal to 60 mm, and the fourth distance is greater than zero and less than or equal to 100 mm. For example, the fourth distance is 10 mm, 20 mm, 50 mm, 70 mm, 100 mm, and the third distance is 10 mm, 20 mm, 50 mm, 60 mm.

[0091] Further, in one embodiment, as Figure 7As shown, it further includes a third hinge 430. The third hinge 430 includes a third hinge plate 431, a third hinge shaft 432, and a fourth hinge shaft 433. The third hinge plate 431 includes a mounting plate 4311 and a connecting plate 4312. The mounting plate 4311 is mounted on the front surface (middle cross beam) 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 third hinge shaft 432 is disposed on the first side, and the bottom of the first door 110 is hinged to the third hinge shaft 432. The fourth hinge shaft 433 is disposed on the second side, and the top of the second door 120 is hinged to the fourth hinge shaft 433.

[0092] Exemplarily, the third hinge plate 431 can be made of a metal material or a non-metal material with a certain structural strength. The third hinge plate 431 includes a mounting plate 4311 and a connecting plate 4312 that are 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 sheet of material. Thereafter, the connecting plate 4312 can be bent relative to the mounting plate 4311 by means of stamping and folding.

[0093] The two sides in the thickness direction of the connecting plate 4312 are respectively the first side and the second side. The third hinge shaft 432 is fixedly connected to the first side, and the fourth hinge shaft 433 is fixedly connected to the second side.

[0094] During actual production and manufacturing, the third hinge shaft 432 and the fourth hinge shaft 433 can be fixedly connected to the connecting plate 4312 by welding respectively. Alternatively, the third hinge shaft 432 and the fourth hinge shaft 433 can be configured as an integral part in the shape of a long bar. The connecting plate 4312 is provided with through holes penetrating along its thickness direction. The integral part is inserted into the through holes, and the integral part is fixed in the through holes by welding or threaded connection. The two ends of the integral part in the length direction on the connecting plate 4312 are respectively formed as the third hinge shaft 432 and the fourth hinge shaft 433.

[0095] During actual installation, multiple threaded holes can be provided in advance on the front surface of the box body 500 according to the installation position of the door 100. For example, as Figure 2As shown, a plurality of threaded holes are provided at the position corresponding to the gap between the first door 110 and the second door 120 on the front face of the cabinet body 500. Then, the mounting holes on the mounting plate 4311 of the third hinge plate 431 are aligned with the positions of the threaded holes, and the mounting plate 4311 is fixed to the front face of the cabinet body 500 by means of bolts. At this time, the connecting plate 4312 extends towards the direction of the door 100. At the same time, the third hinge shaft 432 extends upward along the height direction of the cabinet body 500, and the fourth hinge shaft 433 extends downward along the height direction of the cabinet body 500.

[0096] Based on this, when installing the door 100, a hinge hole can be provided in advance at the bottom of the first door 110 corresponding to the third hinge shaft 432, and a hinge hole can be provided in advance at the top of the second door 120 corresponding to the fourth hinge shaft 433. Then, the third hinge shaft 432 and the fourth hinge shaft 433 can be respectively inserted into the hinge holes of their corresponding doors 100, thereby realizing the installation of the door 100.

[0097] In one embodiment, in order to ensure that the traction assembly 310 can drive the sliding door assembly 320 to move, 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, the second rotating shaft fixing seat 313 is connected to the front face of the cabinet body 500, 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 door 100, 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 door 100. Among them, the second rotating shaft fixing seat 313 is located within the installation area (the first installation area A, the second installation area B). For example, the second rotating shaft fixing seat 313 is installed in the installation area by screws.

[0098] Exemplarily, the hinge 400 can include a hinge plate and a hinge shaft, and the hinge shaft is fixedly arranged on the hinge plate by means of welding or the like. During actual installation, the hinge plate can be fixedly arranged on the cabinet body 500 by means of bolts or other structures. Threaded holes can be provided in the door 100 in advance. After the hinge plate is fixed to the cabinet body 500, the hinge shaft can be inserted into the hinge hole of the door 100, thereby realizing the rotational connection of the door 100 relative to the cabinet body 500.

[0099] In the traction assembly 310, the first rotating shaft fixing seat 312 is arranged on the sliding door assembly 320, the second rotating shaft fixing seat 313 is arranged on the front face and close to the hinge plate, and both ends of the traction rod 311 are rotatably connected to the first rotating shaft fixing seat 312 and the second rotating shaft fixing seat 313 respectively.

[0100] In actual use, when the box door 100 rotates between positions of opening or closing the storage space relative to the box 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 box door 100 in the width direction of the box door 100.

[0101] Furthermore, 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 100 under the drive of the traction assembly 310, as Figure 8 and Figure 9 shown, the sliding door assembly 320 includes: a base 321, a first slider 322, a second slider 323 and a connecting member 324.

[0102] Specifically, a first guide rail is formed on one side of the base 321, and a second guide rail is formed on the other side; the first slider 322 is slidably disposed on the first guide rail, 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 and is connected to the cabinet door 200; both ends of the connecting member 324 are respectively connected to the first slider 322 and the second slider 323.

[0103] During the opening or closing process of the box door 100, the traction rod 311 drives the first slider 322 to move on the first guide rail, and the first slider 322 drives the second slider 323 to move in the opposite direction on the second guide rail through the connecting member 324.

[0104] Exemplarily, the base 321 has a first guide rail and a second guide rail arranged side by side and spaced apart. The first slider 322 is disposed on the first guide rail, and the first slider 322 can slide along the length direction of the first guide rail. The second slider 323 is disposed on the second guide rail, and the second slider 323 can slide along the length direction of the second guide rail. Moreover, the first slider 322 and the second slider 323 are connected by the connecting member 324. When the first slider 322 moves on the first guide rail, the first slider 322 can pull the second slider 323 to move on the second guide rail through the connecting member 324, and the moving direction of the second slider 323 is opposite to the moving direction of the first slider 322.

[0105] As a specific implementation manner, as Figure 8 and Figure 9As shown, the two opposite sides of the base 321 in the thickness direction are the first side and the second side respectively. U-shaped grooves are formed on the first side and the second side respectively. The U-shaped groove on the first side is the first guide rail, and the U-shaped groove on the second side is the second guide rail. The first guide rail and the second guide rail extend along the length direction of the base 321. The first slider 322 is slidably disposed in the first guide rail, and the second slider 323 is slidably disposed in the second guide rail. Moreover, 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.

[0106] Considering the requirements in practical applications, limit structures can also be provided at the ends on both sides of the first guide rail and the second guide rail. Through the limitation of the limit structures, the first slider 322 and the second slider 323 can move within a set moving range, so as to set the moving distance according to requirements to meet the usage requirements of different occasions.

[0107] Correspondingly, the traction rod 311 is configured as a long straight rod. One end of the traction rod 311 is rotatably connected to the first rotating shaft fixing seat 312 via the first rotating shaft, and the other end is rotatably connected to the second rotating shaft fixing seat 313 via the second rotating shaft.

[0108] As an implementation manner, as Figure 9 shown, the first rotating shaft fixing seat 312 includes a first vertical plate and a first horizontal plate. The first vertical plate and the first horizontal plate are connected to each other and form an L-shaped structure. The first horizontal plate is provided with a shaft hole, and the first rotating shaft is inserted into the shaft hole. One end of the traction rod 311 is rotatably connected to the first rotating shaft, so as to be fixedly connected to the first rotating shaft fixing seat 312. The first vertical plate can be fixedly connected to the first slider 322 by means of welding or the like.

[0109] Similarly, as Figure 8 and Figure 9 shown, the second rotating shaft fixing seat 313 includes a second vertical plate and a second horizontal plate. The second vertical plate and the second horizontal plate are connected to each other and form an L-shaped structure. The second horizontal plate is provided with a shaft hole, and the second rotating shaft can be inserted into the shaft hole. The other end of the traction rod 311 is rotatably connected to the second rotating shaft, so as to be rotatably connected to the second rotating shaft fixing seat 313.

[0110] To ensure that the first slider 322 and the second slider 323 can move synchronously and in opposite directions, exemplarily, the connecting member 324 includes a first connecting member 3241 and a second connecting member 3242, and the first connecting member 3241 and the second connecting member 3242 are configured as flexible ropes. In the length direction of the base 321, the first connecting member 3241 bypasses the end of the base 321, and its two ends respectively enter the first guide rail and the second guide rail, and are respectively connected to the first slider 322 and the second slider 323. Correspondingly, the second connecting member 3242 bypasses the other end of the base 321, and its two ends also respectively enter the first guide rail and the second guide rail, and are respectively connected to the first slider 322 and the second slider 323. 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.

[0111] 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 front of the box body 500 by means of structures such as bolts.

[0112] Then, the base 321 can be fixed on the door 100 by means of structures such as bolts. Exemplarily, engaging plates 325 are respectively arranged on both sides in the length direction of the base 321, and through holes are respectively arranged on the two engaging plates 325. During installation, external bolt holes can pass through the through holes on the two engaging plates 325 and be connected to the door 100, so as to fix the base 321 on the door 100.

[0113] 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.

[0114] During actual use, as Figure 8 and Figure 9 shown, when the door 100 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 follows the hinge seat and is fixed on the door 100, during the rotation of the door 100, the first slider 322 will move along the first direction on the first guide rail. Correspondingly, the first slider 322 will pull the second slider 323 to move along the second direction on the second guide rail through the first connecting member 3241. Since the base 321 is fixedly connected to the door 100 and the second slider 323 is fixedly connected to the cabinet door 200, at this time, the cabinet door 200 will move along the second direction relative to the door 100. Among them, the first direction is opposite to the second direction, and both the first direction and the second direction are parallel to the width direction of the door 100.

[0115] Correspondingly, when the door 100 of the box moves from the position of opening the storage space towards the position of closing the storage space relative to the box body 500, during the rotation of the door 100 of the box, the first slider 322 will move along the first guide rail in a direction opposite to the first direction. Correspondingly, the first slider 322 will pull the second slider 323 to move along the second guide rail in a direction opposite to the second direction through the second connecting member 3242. At this time, the cabinet door 200 will move relative to the door 100 of the box in a direction opposite to the second direction.

[0116] In another embodiment of the present utility model, as Figure 10 and Figure 11 shown, the sliding door mechanism 300 includes: a base 321, a first slider 322, a second slider 323, and a transmission member 328. A first guide rail is formed on one side of the base 321, and a second guide rail is formed on the other side. The first slider 322 is slidably disposed on the first guide rail, and the second slider 323 is slidably disposed on the second guide rail. Both ends of the transmission member 328 are respectively in transmission connection with the first slider 322 and the second slider 323. When the first slider 322 moves on the first guide rail, the first slider 322 drives the second slider 323 to move in the opposite direction along the second guide rail through the connecting member 324.

[0117] The base 321 can be fixed to the door 100 of the box 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 hole can pass through the through holes on the first receiving plate 326 and the second receiving plate 327 and be connected to the door 100 of the box, so as to fix the base 321 to the door 100 of the box.

[0118] In some embodiments, the traction assembly includes: a first link and a second link. The first end of the first link is rotatably provided on the front surface of the box body 500 and is arranged offset from the hinge axis.

[0119] Among them, the first end of the first link is rotatably provided 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 provided on the door 100 of the box and is meshed and connected to the tooth portion on the first slider 322 through a gear provided at the second end of the second link.

[0120] It can be understood that the first link and the second link are connected by a hinge, 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 door 100 of the box.

[0121] When the second end of the second link moves in a circular motion around the hinge axis with the door 100 of the box, since the first end of the first link is arranged out of alignment 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 door 100 remains unchanged. As a result, the second end of the second link rotates around the door 100, driving the second slider 323 to drive the cabinet door 200 to move along the width direction of the door 100 of the box.

[0122] In practical applications, during the opening process of the door 100 of the box, the door 100 of the box drives the second end of the second link to rotate relative to the hinge axis. Based on the misaligned arrangement of the first end of the first link and the hinge axis, the distance between the first end of the first link and the second end of the second link increases, driving the second end of the second link to rotate clockwise relative to the door 100 of the box. Furthermore, it controls the second slider 323 to drive the cabinet door 200 to move along the width direction of the door 100 of the box away from the hinge 400, that is, to move to the left relative to the door 100 of the box. In this way, it can avoid interference between the cabinet door 200 and the cabinet doors 200 on the side cabinets; during the closing process of the door 100 of the box, the door 100 of the box drives the second end of the second link to rotate relative to the hinge axis. Based on the misaligned arrangement of the first end of the first link and the hinge axis, the distance between the first end of the first link and the second end of the second link decreases, driving the second end of the second link to rotate counterclockwise relative to the door 100 of the box. Furthermore, it controls the second slider 323 to drive the cabinet door 200 to move along the width direction of the door 100 of the box towards the hinge 400, that is, to move to the right relative to the door 100 of the box. In this way, it can ensure that the cabinet door 200 can avoid the cabinet doors 200 of the side cabinets when the door 100 of the box is closed and reset the cabinet door 200.

[0123] In an optional embodiment, the first rotating shaft fixing seat 312 is connected to the first slider 322, and the second slider 323 is connected to the cabinet door 200. Among them, the first guide rail and the second guide rail, as a kind of track, the first slider 322 and the second slider 323 are sliding members adapted to the corresponding guide rails and can slide along the corresponding guide rails; in addition, the sliding fit between the first slider 322 and the first guide rail should at least include the case where there are balls arranged between the first slider 322 and the first guide rail, and the sliding fit between the second slider 323 and the second guide rail should at least include the case where there are balls arranged between the second slider 323 and the second guide rail.

[0124] As Figure 10 shown, the transmission member 328 includes: a first rack 3281, a second rack 3282, and a gear 3283. Among them, the first rack 3281 is arranged on the first slider 322, and the second rack 3282 is arranged on the second slider 323. The gear 3283 is rotatably arranged on the base 321 and meshes with the first rack 3281 and the second rack 3282.

[0125] In this embodiment, when the first slider 322 slides along the first guide rail, the first rack 3281 slides with the first slider 322. The first rack 3281 meshes with the gear 3283. When the first rack 3281 slides, it drives the gear 3283 to rotate. The second rack 3282 and the first rack 3281 respectively mesh with both sides of the gear 3283. When the gear 3283 rotates, it can drive the second rack 3282 to slide in the opposite direction relative to the first rack 3281, thereby driving the second slider 323 to slide in the opposite direction relative to the first slider 322. The structure is simple, convenient and practical.

[0126] As Figure 10 shown, the transmission member 328 further includes: a pin shaft. The pin shaft is arranged on the base 321, and the gear 3283 is rotatably arranged on the pin shaft.

[0127] In this embodiment, the pin shaft is arranged on the base 321 to arrange the gear 3283. The gear 3283 is rotatably arranged on the pin shaft and can rotate around the pin shaft to transmit power between the first rack 3281 and the second rack 3282, so that the first rack 3281 and the second rack 3282 slide in opposite directions, and the first slider 322 and the second slider 323 can slide in opposite directions.

[0128] In addition, as described above, in this embodiment, a refrigeration device is further provided. The refrigeration device includes a box body 500 and the door body device described in the above embodiment. The box body 500 forms a storage space. The box door 100 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.

[0129] 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 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. In addition, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
