[0052] As Figure 2 shown, the door body device in the embodiment of the present utility model includes: a box door 100, a cabinet door 200, and a sliding door mechanism 300.

[0053] Among them, the box door 100 can be 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; the cabinet door 200 is slidably disposed outside the box door 100; the sliding door mechanism 300 includes a connected traction assembly 310 and a sliding door assembly 320. The traction assembly 310 is at least disposed on the top wall 501 of the box body 500, and the sliding door assembly 320 is disposed on the box door 100 and is connected to the cabinet door 200. The traction assembly 310 is configured to drive the sliding door assembly 320 to act during the opening or closing process of the box door 100, and further drive the cabinet door 200 to move in the width direction of the box door 100.

[0054] Among them, the thickness of the cabinet door 100 is 18 - 60 mm. Exemplarily, the thickness of the cabinet door 100 is 18 mm, 25 mm, 50 mm, 60 mm, etc. The thickness of the door 200 is 12 - 26 mm. Exemplarily, the thickness of the door 200 is 12 mm, 18 mm, 24 mm, 26 mm, etc. In addition, the door 200 can be a wooden door, a plastic door, or the like.

[0055] It can be understood that the door device in this embodiment can be used in refrigeration devices such as refrigerators, freezers, ice makers, etc. Among them, the refrigeration device includes a cabinet 500, and a storage space is formed in the cabinet 500, 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 cabinet 500 of the refrigeration device, and the refrigeration device can perform refrigeration processing on the storage space.

[0056] In this embodiment, the cabinet door 100 in the door device is rotatably arranged on the cabinet 500 of the refrigeration device through a hinge 400. The cabinet door 100 can be used to open or close the storage space in the cabinet 500. When the cabinet 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 cabinet 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.

[0057] For the convenience of describing the positional relationship between each component, in this embodiment, as Figure 2 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.

[0058] A storage space is provided inside the cabinet 500. An opening is provided on the side of the cabinet 500 in the thickness direction, and the opening communicates with the storage space. The cabinet door 100 is connected to the side of the cabinet 500 in the thickness direction where the opening is provided. The cabinet door 100 extends along the width direction of the cabinet 500. A hinge 400 is connected to one side of the cabinet door 100 in the width direction of the cabinet 500. The cabinet door 100 can be rotatably connected to the cabinet 500 through the hinge 400, so as to ensure that the cabinet door 100 can open or close the storage space of the cabinet 500.

[0059] Moreover, the side of the cabinet 500 where the cabinet door 100 is installed is the front side, that is, the cabinet door 100 is installed on the front side of the cabinet 500.

[0060] The box door 100 is generally constructed as a flat plate-like structure with a certain thickness. The box 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 box 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 box door 100 in the width direction can be rotatably connected to the box body 500 via a hinge 400. For example, as Figure 2 shown, a hinge 400 is connected to the right side of the box door 100 in the width direction of the box body 500, and the box door 100 can be rotatably connected to the box body 500 via this hinge 400.

[0061] Moreover, when the box door 100 is in the position state of closing the storage space of the box body 500, the width direction of the box door 100 is parallel to the width direction of the box body 500, and the thickness direction of the box door 100 is parallel to the thickness direction of the box body 500.

[0062] 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 100 facing away from the box body 500. When the refrigeration device is placed together with the cabinet in an embedded manner or directly placed in the cabinet, after the box 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 box door 100 can be flush with the outer wall surface of the cabinet.

[0063] 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.

[0064] After the door body device in the present embodiment is installed on the box body 500 of the refrigeration device, when the box door 100 rotates relative to the box body 500 to open or close the storage space of the box body 500, the sliding door mechanism 300 can drive the cabinet door 200 to move relative to the box door 100 in the width direction of the box door 100. Thus, when the refrigeration device is placed in the cabinet in an embedded manner, without affecting the coordination and aesthetics and the user experience, interference between the cabinet door 200 and the cabinet can be avoided during the process of opening the box door 100.

[0065] 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 510 and the second cabinet 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 can avoid the side walls of the first cabinet 510 and the second cabinet 520;

[0066] Alternatively, the door body device and the box body 500 are configured to be disposed in a 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 wall of the cabinet body.

[0067] It can be understood that the refrigeration device includes a door body device and a box body 500.

[0068] In practice, as Figure 1 shown, when the refrigeration device having the door body device and the box body 500 is placed between adjacent first cabinet body 510 and second cabinet body 520, a cabinet door 200 can be disposed 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 a 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.

[0069] 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.

[0070] Or, after the refrigeration device is placed in the cabinet body, a cabinet door 200 can be disposed 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 a 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.

[0071] 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 wall of the cabinet body.

[0072] Furthermore, in one embodiment, the number of the box doors 100 is multiple, and each box door 100 corresponds to at least one storage space; each box door 100 is rotatably connected to the box body 500 through a plurality of hinges 400.

[0073] It can be understood that according to different refrigeration requirements, the cabinet 500 of different refrigeration devices can be provided with different numbers of storage spaces, which are spaced along the height direction of the cabinet 500. Some storage spaces are for refrigeration, and some are for freezing. Correspondingly, in order to be able to close these storage spaces targeted, the number of the cabinet doors 100 can be multiple, and each cabinet door 100 corresponds to at least one of the storage spaces.

[0074] For example, as Figure 2 shown, the cabinet 500 is provided with two storage spaces spaced along the vertical direction. These two storage spaces can be used for refrigeration and freezing respectively. The number of the cabinet doors 100 is two, namely the first cabinet door 110 and the second cabinet door 120. The two cabinet doors 100 correspond to the two storage spaces one by one. At this time, the two storage spaces can be opened or closed independently through the two cabinet doors 100.

[0075] For another example, the cabinet 500 can be provided with three storage spaces spaced along 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 second space is for freezing. The number of the cabinet doors 100 is two, namely the first cabinet door 110 and the second cabinet door 120. Among them, the first cabinet door 110 corresponds to the first space and the second space one by one, and the second cabinet door 120 corresponds to the third space. At this time, the first space and the second space can be opened or closed simultaneously by using the first cabinet door 110, and the opening and closing state of the third space can be controlled independently by using the second cabinet door 120.

[0076] It can be understood that in this embodiment, each cabinet door 100 can correspond to a single storage space. At this time, the cabinet door 100 can control the opening and closing state of the storage space independently. In actual use, according to requirements, each cabinet door 100 can also correspond to multiple adjacent storage spaces. At this time, the cabinet door 100 can control the opening and closing states of the multiple storage spaces simultaneously.

[0077] In a specific embodiment, as Figure 2 shown, the door body device includes the first cabinet door 110 and the second cabinet door 120. The first cabinet door 110 and the second cabinet door 120 are spaced 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 the first hinge 410 provided on the top wall 501 of the cabinet 500, and the bottom of the second cabinet door 120 can be rotatably connected to the cabinet 500 by means of the second hinge 420 provided on the front surface (lower cross beam) of the cabinet 500.

[0078] Correspondingly, as Figure 3 and Figure 4As shown, the traction assembly 310 located on the top wall 501 of the box body 500 is disposed near 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 box door 110 to move relative to the first box door 110 in the width direction.

[0079] Further, in order to effectively implement the installation of the box door 100, the hinge 400 may further include a third hinge 430. Among them, the third hinge 430 is disposed on the front surface (middle cross beam) of the box body 500, and the third hinge 430 is located between the first hinge 410 and the second hinge 420.

[0080] Exemplarily, since multiple box doors 100 are arranged at intervals in the height direction of the box body 500, a third hinge 430 may be disposed at the position between two adjacent box doors 100, and at least one of the two adjacent box doors 100 may be rotatably connected to the box body 500 by means of the third hinge 430.

[0081] In practical applications, the number of the third hinges 430 may be one or two. For example, when the number of the third hinges 430 is one, one of the two adjacent box doors 100 may be connected to the third hinge 430 and rotatably connected to the box body 500 by means of the one third hinge 430, or the two adjacent box doors 100 may be simultaneously connected to the third hinge 430 and rotatably connected to the box body 500 by means of the one third hinge 430 at the same time.

[0082] For example, as Figure 2 shown, the box door 100 includes a first box door 110 and a second box door 120. At this time, the third hinge 430 may be disposed between the first box door 110 and the second box door 120, and the bottom of the first box door 110 and the top of the second box door 120 may be simultaneously hinged to the third hinge 430, so as to be rotatably connected to the box body 500.

[0083] In yet another embodiment, when the number of the third hinges 430 is two, the two third hinges 430 may be arranged at intervals in the height direction of the box body 500. At this time, the two adjacent box doors 100 may be respectively hinged to the two third hinges 430, and then rotatably connected to the box body 500 by means of their respective third hinges 430.

[0084] 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 501 of the box body 500 and the remaining part protrudes from the top wall 501 towards the corresponding box door 100. The first hinge shaft 412 extends downward from the part of the first hinge plate 411 protruding from the top wall 501, and the top of the corresponding box door 100 is hinged to the first hinge shaft 412.

[0085] 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 portion and a first protruding portion connected to each other.

[0095] Similarly, the second hinge plate 421 and the second hinge shaft 422 can also be made of metal or non-metallic 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 roughly perpendicular to the support plate 4211. The two can be integrally formed by stamping or the like. The support plate 4211 is provided with a plurality of mounting holes. The second hinge shaft 422 is fixed on the extension plate 4212 by welding or threaded connection.

[0096] During actual installation, multiple threaded holes can be set in advance on the front side of the box 500 and near the bottom, and then one side of the support plate 4211 in the thickness direction is fitted to the front side of the box 500, and then the mounting holes on the support plate 4211 are made to correspond to the positions of the threaded holes, and then the support plate 4211 is fixed to the front side of the box 500 with the help of bolts.

[0098] Further, in one embodiment, if Figure 7 As shown, 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 of the box body 500. The connecting plate 4312 is connected to the side of the mounting plate 4311 away from the front of the box body 500. The connecting plate 4312 is arranged at an angle to the mounting plate 4311. The connecting plate 4312 has a first side and a second side opposite to each other. The three hinge shafts 432 are arranged on the first side, the bottom of the first door 110 is hinged to the third hinge shaft 432, the fourth hinge shaft 433 is arranged on the second side, the top of the second door 120 is hinged to the fourth hinge shaft 433, and the third hinge 430 can be provided with at least one traction assembly 310, wherein, in the case of two traction assemblies 310, one traction assembly 310 corresponds to the first door 110, and the other traction assembly 310 corresponds to the second door 120.

[0099] Exemplarily, the third hinge plate 431 can be made of a metal material or a non-metal material with a certain structural strength, and the third 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, and a plurality of mounting holes are provided on the mounting plate 4311. In 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 stamping and folding.

[0100] Two sides of the connecting plate 4312 in the thickness direction are respectively a first side and a second side. The first side is fixedly connected to the third hinge shaft 432 , and the second side is fixedly connected to the fourth hinge shaft 433 .

[0101] 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 constructed 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. This 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.

[0102] During actual installation, multiple threaded holes can be set in advance on the front surface of the box body 500 according to the installation position of the box door 100. For example, as shown in the figure, multiple threaded holes are set at the position corresponding to the gap between the first box door 110 and the second box door 120 on the front surface of the box 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 then the mounting plate 4311 is fixed to the front surface of the box body 500 by means of bolts. At this time, the connecting plate 4312 extends towards the direction of the box door 100. At the same time, the third hinge shaft 432 extends upwards along the height direction of the box body 500, and the fourth hinge shaft 433 extends downwards along the height direction of the box body 500.

Then, the third hinge shaft 432 and the fourth hinge shaft 433 can be respectively inserted into the hinge holes of their corresponding box doors 100, and thus, the installation of the box door 100 can be realized.

[0104] 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 top wall of the box 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 box door 100, the traction rod 311 drives the sliding door assembly 320 to act, and further drives the cabinet door 200 to move relative to the width direction of the box door 100. Among them, the second rotating shaft fixing seat 313 is located in the installation area A. For example, the second rotating shaft fixing seat 313 is installed in the installation area A by screws.

[0105] Exemplarily, the hinge 400 may include a hinge plate and a hinge shaft, and the hinge shaft is fixedly arranged on the hinge plate by means such as welding. During actual installation, the hinge plate can be fixedly arranged on the box body 500 by means of structures such as bolts. The cabinet door 100 can be provided with threaded holes in advance. After the hinge plate is fixed to the box body 500, the hinge shaft can be inserted into the hinge hole of the cabinet door 100, so as to realize the rotational connection of the cabinet door 100 relative to the box body 500.

[0106] In the traction assembly 310, the first rotating shaft fixed seat 312 is arranged on the sliding door assembly 320, the second rotating shaft fixed seat is arranged on the top wall 501 and close to the hinge plate, and the two ends of the traction rod 311 are respectively rotatably connected to the first rotating shaft fixed seat 312 and the second rotating shaft fixed seat 313.

[0107] During actual use, when the cabinet door 100 rotates between the 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 cabinet door 100 in the width direction of the cabinet door 100. Among them, an installation groove can be arranged on the cabinet door 100 to facilitate the arrangement of the sliding door assembly 320.

[0108] 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 cabinet 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.

[0109] 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 arranged on the first guide rail, and the first rotating shaft fixed seat 312 is connected to the first slider 322; the second slider 323 is slidably arranged on the second guide rail and is connected to the cabinet door 200; the two ends of the connecting member 324 are respectively connected to the first slider 322 and the second slider 323.

[0110] During the opening or closing process of the cabinet 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.

[0111] 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 a 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.

[0112] As a specific implementation manner, as Figure 8 and Figure 9 shown, the opposite sides in the thickness direction of the base 321 are respectively a first side and a second side. U-shaped grooves are respectively formed on the first side and the second side. 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.

[0113] 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 in different occasions.

[0114] 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 a first rotating shaft, and the other end is rotatably connected to the second rotating shaft fixing seat 313 via a second rotating shaft.

[0115] 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 a 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.

[0116] Similarly, as Figure 8 and Figure 9As 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 a 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.

[0117] 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.

[0118] 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 top wall 501 of the box body 500 by means of structures such as bolts.

[0119] Then, the base 321 can be fixed on the box door 100 by means of structures such as bolts. Exemplarily, joint 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 joint plates 325. During installation, an external bolt hole can pass through the through holes on the two joint plates 325 and be connected to the box door 100, so as to fix the base 321 on the box door 100.

[0120] 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.

[0121] During actual use, as Figure 8 and Figure 9As shown, when the door 100 of the box 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 100 following the hinge seat, 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 relative to the door 100 along the second direction. Wherein, 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.

[0122] Correspondingly, when the door 100 of the box 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 100, the first slider 322 will move along the direction opposite to the first direction on the first guide rail. Correspondingly, the first slider 322 will pull the second slider 323 to move along the direction opposite to the second direction on the second guide rail through the second connecting member 3242. At this time, the cabinet door 200 will move relative to the door 100 along the direction opposite to the second direction.

[0123] Furthermore, in yet another specific implementation, as Figure 10 、 Figure 11 and Figure 12 shown, the base 321 is configured as a plate-like structure with a certain length. The first guide rail and the second guide rail are respectively arranged on both sides of the width direction of the base 321, and moreover, both the first guide rail and the second guide rail extend along the length direction of the base 321. The first slider 322 is slidably arranged on the first guide rail, and the second slider 323 is slidably arranged on the second guide rail.

[0124] 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 top wall 501 of the box body 500.

[0125] Wherein, 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 door 100 and is meshed and connected to the tooth part on the first slider 322 through a gear arranged at the second end of the second link.

[0126] 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.

[0127] When the second end of the second link rotates in a circular motion around the hinge axis with the door 100, since the first end of the first link is misaligned 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 and drives the second slider 323 to drive the cabinet door 200 to move along the width direction of the door 100.

[0128] In practical applications, during the opening process of the door 100, the door 100 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. Further, it controls the second slider 323 to drive the cabinet door 200 to move along the width direction of the door 100 away from the hinge 400, that is, move to the left relative to the door 100. In this way, it can avoid interference between the cabinet door 200 and the cabinet door 200 on the side cabinet; during the closing process of the door 100, the door 100 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. Further, it controls the second slider 323 to drive the cabinet door 200 to move along the width direction of the door 100 towards the hinge 400, that is, move to the right relative to the door 100. In this way, it can ensure that the cabinet door 200 can avoid the cabinet door 200 on the side cabinet when the door 100 is closed and reset the cabinet door 200.

[0129] 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. Correspondingly, the towing rod 311 can be configured as an arc-shaped rod. One end of the towing 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.

[0130] As a realization method, a first clamping portion is provided on the first rotating shaft fixing seat 312. The first clamping portion includes two clamping plates arranged side by side at intervals. 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. One end of the towing rod 311 can be placed between the two clamping plates, and the end of the towing rod 311 is rotatably connected to the first rotating shaft. Thus, the towing 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 slider 322 by means of welding or the like.

[0131] Similarly, a second clamping portion is provided on the second rotating shaft fixing seat 313. The second clamping portion 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.

[0132] 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.

[0133] 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 top wall 501 of the box body 500 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 front of the box body 500 to fix the second rotating shaft fixing seat 313 on the top wall 501 of the box body 500.

[0134] Then, the base 321 can be fixed on the door 100 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 be passed through the through holes on the first receiving plate 326 and the second receiving plate 327 and connected to the door 100 to fix the base 321 on the door 100.

[0135] 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.

[0136] During actual use, when the door 100 moves relative to the box body 500 from the position of closing the storage space to 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 third direction on the first guide rail. Correspondingly, the first slider 322 will pull the second slider 323 to move along the fourth direction on the second guide rail through the connecting member 324. 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 fourth direction relative to the door 100. Among them, the third direction is opposite to the fourth direction, and both the third direction and the fourth direction are parallel to the width direction of the door 100.

[0137] 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 third direction. Correspondingly, the first slider 322 will pull the second slider 323 through the connecting member 324 to move along the second guide rail in a direction opposite to the fourth direction. At this time, the cabinet door 200 will move relative to the door 100 of the box in a direction opposite to the fourth direction.

[0138] Among them, the first guide rail and the second guide rail are a kind of rails, and the first slider 322 and the second slider 323 are sliding members that are 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.

[0139] Further, 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, the connecting member 324 includes: a first connecting member 3241 and a second connecting member 3242.

[0140] Among them, 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.

[0141] 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 its two ends respectively extend towards the first slider 322 and the second slider 323 and are respectively connected to the first slider 322 and the second slider 323.

[0142] 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.

[0143] 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.

[0144] Exemplarily, to ensure that the first connecting member 3241 and the second connecting member 3242 can normally pull the second slider 323 to move, as shown in the figure, a first roller 328 and a second roller 329 are respectively arranged on both sides in the length direction of the base 321, and the first roller 328 and the second roller 329 can respectively support the first connecting member 3241 and the second connecting member 3242.

[0145] Specifically, the number of the first rollers 328 is two, and 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 seat. To facilitate receiving the first connecting member 3241, a receiving groove extending along its circumferential direction can be arranged on the outer periphery of the first roller 328. 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.

[0146] Similarly, the number of the second rollers 329 is two, and 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 seat. To facilitate receiving the second connecting member 3242, a receiving groove extending along its circumferential direction can also be arranged on the outer periphery of the second roller 329. 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.

[0147] Thus, in the above arrangement, 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 is possible to prevent the first connecting member 3241 and the second connecting member 3242 from contacting other components and causing wear and tear during movement, and an effective protective effect can be exerted on the first connecting member 3241 and the second connecting member 3242.

[0148] 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 device in the above embodiment. Among them, the box body 500 forms a storage space, and 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. It should be particularly noted that the refrigeration device can be a refrigerator.

[0149] 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.
