[0062] In practical applications, in the case where there are multiple door body components 10, the traction component 310 corresponding to one door body component 10 is arranged on the middle cross beam 501 of the box body 500, and the two traction components 310 corresponding to another door body component 10 are respectively located on the middle cross beam 501 and the lower cross beam 502 of the box body 500. That is to say, each door body component 10 is correspondingly provided with at least one sliding door mechanism 300, and the two traction components 310 corresponding to one door body component 10 are respectively located at different positions on the front of the box body 500.

[0063] It can be understood that the door body device in this embodiment can be used in refrigeration equipment such as refrigerators, freezers, ice makers, etc. Among them, the refrigeration equipment includes a box body 500, and the box body 500 forms a storage space, and vegetables, fruits, etc. 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 equipment, and the refrigeration device can perform refrigeration treatment on the storage space.

[0064] In this embodiment, the cabinet door 100 in the door device is rotatably arranged on the cabinet body 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 body 500. When the cabinet door 100 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 100 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.

[0065] For the convenience of describing the positional relationship between the various components, in this embodiment, as Figure 2 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.

[0066] A storage space is provided inside the cabinet body 500. An opening is provided on the side of the cabinet body 500 in the thickness direction, and this opening communicates with the storage space. The cabinet door 100 is connected to the side of the cabinet body 500 in the thickness direction where this opening is provided. The cabinet door 100 extends along the width direction of the cabinet body 500. A hinge 400 is connected to one side of the cabinet door 100 in the width direction of the cabinet body 500. The cabinet door 100 can be rotatably connected to the cabinet body 500 via this hinge 400, so as to ensure that the cabinet door 100 can open or close the storage space of the cabinet body 500. Moreover, the side of the cabinet body 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 body 500.

[0067] The cabinet door 100 is generally constructed as a flat plate-like structure with a certain thickness. The cabinet 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 cabinet 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 cabinet door 100 in the width direction can be rotatably connected to the cabinet body 500 via a hinge 400. For example, as Figure 2 shown, the cabinet door 100 is connected to the hinge 400 on the right side of the cabinet body 500 in the width direction. The cabinet door 100 can be rotatably connected to the cabinet body 500 via this hinge 400.

[0068] Moreover, when the cabinet door 100 is in the position state of closing the storage space of the cabinet body 500, the width direction of the cabinet door 100 is parallel to the width direction of the cabinet body 500, and the thickness direction of the cabinet door 100 is parallel to the thickness direction of the cabinet body 500.

[0069] Furthermore, the cabinet door 200 can be a decorative door panel, which is configured as a flat plate structure with a certain thickness. The cabinet door 200 is connected to the outer side of the door 100 facing away from the cabinet body 500. When the refrigeration device is placed in 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.

[0070] 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.

[0071] In one embodiment, as Figure 1 shown, the door body device and the cabinet 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 opening or closing process of the door 100, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the door 100, so that the cabinet door 200 can avoid the side walls of the first cabinet body 510 and the second cabinet body 520;

[0072] Or, the door body device and the cabinet body 500 are configured to be arranged in the cabinet; during the opening or closing process of the door 100, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the door 100, so that the cabinet door 200 can avoid the side walls of the cabinet.

[0073] It can be understood that the refrigeration device includes a door body device and a cabinet body 500.

[0074] In practice, as Figure 1 shown, when the refrigeration device with the door body device and the cabinet 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 door 100 in the door body device, and the cabinet door 200 can move relative to the door 100 along the width direction of the door 100. Optionally, when the door 100 is in the state of closing the storage space of the cabinet body 500, the outer wall surface of the cabinet door 200 facing away from the 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 door 100 are in the same direction in the thickness direction of the cabinet body 500.

[0075] At this time, during the rotation process of the door 100 relative to the cabinet body 500, the sliding door mechanism 300 can drive the cabinet door 200 to move, so that the cabinet door 200 can avoid the side walls of the first cabinet body 510 and the second cabinet body 520.

[0076] Alternatively, after the refrigeration device is placed in the cabinet, a cabinet door 200 can be provided on the outer side of the box door 100 of the door 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, and the outer wall surface of the cabinet 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.

[0077] At this time, during the rotation of the box door 100 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.

[0078] Thus, after the door device in this embodiment is installed on the box body 500 of the refrigeration device, during the rotation of the box door 100 relative to the box body 500, the sliding door assembly 320 can drive the cabinet door 200 to move relative to the box door 100 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 user experience, the cabinet door 200 can be prevented from interfering with the cabinet during the opening of the box door 100.

[0079] In a specific embodiment, as Figure 2 shown, the door device includes a first box door 110 and a second box door 120. The first box door 110 and the second box door 120 are arranged at intervals along the height direction of the box body 500. At this time, the bottom of the first box door 110 and the top of the second box door 120 are rotatably connected to the box body 500 through a first hinge 410 provided on the middle cross beam 501, and the bottom of the second box door 120 is rotatably connected to the box body 500 through a second hinge 420 provided on the lower cross beam 502 of the box body 500.

[0080] Among them, the traction assembly 310 corresponding to the first box door 110 is arranged close to the first hinge 410, one of the traction assemblies 310 corresponding to the second box door 120 is arranged close to the first hinge 410, and the other traction assembly 310 is arranged close to the second hinge 420.

[0081] That is to say, one sliding door mechanism 300 is provided on the first box door 110, and two sliding door mechanisms 300 are provided on the second box door 120.

[0082] Furthermore, in an embodiment, as Figure 5As shown, the first hinge 410 includes a first hinge plate 411, a second hinge shaft 413, and a third hinge shaft 422. The first hinge plate 411 includes a mounting plate 4111 and a connecting plate 4112. The mounting plate 4111 is mounted on the front surface (the middle cross beam 501) of the box body 500. The connecting plate 4112 is connected to the side of the mounting plate 4111 facing away from the front surface of the box body 500. The connecting plate 4112 is disposed at an angle to the mounting plate 4111. The connecting plate 4112 has opposite first and second sides. The first hinge shaft 412 is disposed on the first side, and the bottom of the first door 110 is hinged to the first hinge shaft 412. The second hinge shaft 413 is disposed on the second side, and the top of the second door 120 is hinged to the second hinge shaft 413.

[0083] Exemplarily, the first hinge plate 411 can be made of a metal material or a non-metal material with a certain structural strength. The first hinge plate 411 includes a mounting plate 4111 and a connecting plate 4112 that are connected to each other. The connecting plate 4112 is substantially perpendicular to the mounting plate 4111. A plurality of mounting holes are provided on the mounting plate 4111. During actual production and manufacturing, the mounting plate 4111 and the connecting plate 4112 can be integrally formed on the same sheet of material. Thereafter, the connecting plate 4112 can be bent relative to the mounting plate 4111 by means of stamping and folding.

[0084] The two sides in the thickness direction of the connecting plate 4112 are respectively the first side and the second side. The first hinge shaft 412 is fixedly connected to the first side, and the second hinge shaft 413 is fixedly connected to the second side.

[0085] During actual production and manufacturing, the first hinge shaft 412 and the second hinge shaft 413 can be fixedly connected to the connecting plate 4112 by welding respectively. Alternatively, the first hinge shaft 412 and the second hinge shaft 413 can be configured as an integrally formed long bar-shaped member. The connecting plate 4112 is provided with a through hole penetrating along its thickness direction. The integrally formed member is inserted into the through hole, and the integrally formed member is fixed in the through hole by welding or threaded connection. The two ends of the integrally formed member in the length direction on the connecting plate 4112 are respectively formed as the third hinge shaft 422 and the fourth hinge shaft 432.

[0086] 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 of the gap between the first box door 110 and the second box door 120 on the front face of the box body 500. Then, the mounting holes on the mounting plate 4111 of the first hinge plate 411 are aligned with the positions of the threaded holes, and the mounting plate 4111 is fixed to the front face of the box body 500 by means of bolts. At this time, the connecting plate 4112 extends in the direction of the box door 100. At the same time, the first hinge shaft 412 extends upward along the height direction of the box body 500, and the second hinge shaft 413 extends downward along the height direction of the box body 500.

[0087] Based on this, when installing the box door 100, a hinge hole can be provided in advance at the bottom of the first box door 110 corresponding to the first hinge shaft 412, and a hinge hole can be provided in advance at the top of the second box door 120 corresponding to the second hinge shaft 413. Then, the first hinge shaft 412 and the second hinge shaft 413 can be inserted into the hinge holes of their respective corresponding box doors 100, respectively. Thus, the installation of the box door 100 can be achieved.

[0088] In this way, the two traction components 310 on the middle cross beam 501 of the box body 500 are arranged close to the mounting plate 4111.

[0089] In addition, as Figure 3 shown, the first installation area A is located on the middle cross beam 501 of the box body 500. The two traction components 310 are arranged in the first installation area A. The first installation area A is arranged close to the mounting plate 4111. The first installation area A includes a first sub - area A1 above the mounting plate 4111 and a second sub - area A2 below the mounting plate 4111. The traction component 310 corresponding to the first box door 110 is arranged in the first sub - area A1, and one traction component 310 corresponding to the second box door 120 is arranged in the second sub - area A2;

[0090] Among them, the first sub - area A1 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, and the second side and the fourth side are arranged opposite to each other. The first side is the top edge of the mounting plate 4111. The second side is located in the plane of the side of the box body 500. In the height direction of the box body 500, there is a first distance between the third side and the first side; in the width direction of the box body 500, there is a second distance between the fourth side and the second side; The second sub - area A2 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, and the second side and the fourth side are arranged opposite to each other. The first side is the bottom edge of the mounting plate 4111. The second side is located in the plane of the side of the box body 500. In the height direction of the box body 500, there is a third distance between the third side and the first side; in the width direction of the box body 500, there is a fourth distance between the fourth side and the second side.

[0091] 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.

[0092] 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.

[0093] Further, in one embodiment, as Figure 6 shown, the second hinge 420 includes a second hinge plate 421 and a third 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 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 third 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 third hinge shaft 422.

[0094] Similarly, the second hinge plate 421 can also be made of a metal or non-metal material 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. The two can be integrally formed by stamping or other methods. The support plate 4211 is provided with a plurality of mounting holes. The third hinge shaft 422 is fixedly arranged on the extension plate 4212 by welding or threaded connection or other methods.

[0095] 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 near the bottom. Then, let one side in the thickness direction of the support plate 4211 fit to the front surface of the box body 500. Then, 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 in the thickness direction of the support plate 4211 and extends toward the direction where the door 100 is located. Moreover, the second hinge shaft 413 extends upward along the height direction of the box body 500.

[0096] Based on this, when installing the door 100, an articulated hole can be set in advance at the bottom of the door 100 corresponding to the second hinge 420. Then, insert the second hinge shaft 413 into the articulated hole. Thus, the installation of the door 100 can be achieved.

[0097] Thus, the traction assembly 310 located on the lower cross beam 502 of the box body 500 is disposed close to the second hinge plate 421. As Figure 4 shown, the second installation area B is located on the lower cross beam 502 of the box body 500. The traction assembly 310 is disposed within the second installation area B. In other words, another traction assembly 310 corresponding to the second box door 120 is disposed within the second installation area B. 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 oppositely disposed, and the second side and the fourth side are oppositely disposed. The top edge of the first side support plate 4211, and the second side is located within the plane of the side surface of the box body 500. In the height direction of the box body 500, a fifth distance is left between the third side and the first side; in the width direction of the box body 500, a sixth distance is left between the fourth side and the second side.

[0098] In an alternative embodiment, the fifth distance is greater than zero and less than or equal to 60 mm, and the sixth distance is greater than zero and less than or equal to 100 mm. For example, the sixth distance is 10 mm, 20 mm, 50 mm, 70 mm, 100 mm, and the fifth distance is 10 mm, 20 mm, 50 mm, 60 mm.

[0099] Further, in one embodiment, as Figure 7 shown, a third hinge 430 is further included. The third hinge 430 includes a third hinge plate 431 and a fourth hinge shaft 432. A part of the third hinge plate 431 covers the top wall of the box body 500 and the remaining part protrudes from the top wall towards the corresponding box door 100. The fourth hinge shaft 432 extends downward from the part of the third hinge plate 431 protruding from the top wall. The top of the first box door 110 is hinged to the fourth hinge shaft 432.

[0100] Exemplarily, the third hinge plate 431 can be made of a metal or non-metal material with a certain structural strength. The third hinge plate 431 includes a first fitting portion and a first protruding portion that are connected to each other. The first fitting portion is provided with a plurality of mounting holes, and the first hinge shaft 412 is fixedly disposed on the first protruding portion by means of welding or threaded connection.

[0101] 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 to the top wall of the box body 500, and at the same time, the mounting holes on the first fitting portion are made to correspond to 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 to the top wall of the box body 500, the first protruding portion can protrude from the top wall towards the box door 100, and moreover, the first hinge shaft 412 can extend downward along the height direction of the box body 500.

[0102] Based on this, when installing the cabinet door 100, a hinge hole can be set in advance at the top of the cabinet door 100 corresponding to the third hinge 430, and then the fourth hinge shaft 432 is inserted into the hinge hole, thereby realizing the installation of the cabinet door 100.

[0103] In one embodiment, 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 surface 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 cabinet 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 cabinet 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.

[0104] 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 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 set in the cabinet 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 cabinet door 100, thereby realizing the rotational connection of the cabinet door 100 relative to the cabinet body 500.

[0105] 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 surface and is 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.

[0106] During actual use, when the cabinet door 100 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 100 in the width direction of the cabinet door 100.

[0107] Furthermore, in one embodiment, 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.

[0108] 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.

[0109] 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.

[0110] Exemplarily, the base 321 has the first guide rail and the 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 that of the first slider 322.

[0111] As a specific implementation manner, as Figure 8 and Figure 9 shown, the opposite two sides in the thickness direction of the base 321 are respectively the first side and the 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.

[0112] 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 use requirements of different occasions.

[0113] 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.

[0114] As an implementation, 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, and thus is 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 such as welding.

[0115] 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 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, and thus is rotatably connected to the second rotating shaft fixing seat 313.

[0116] 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.

[0117] 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.

[0118] Then, the base 321 can be fixed on the door 100 by means of structures such as bolts. Exemplarily, engagement 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 engagement plates 325. During installation, external bolt holes can pass through the through holes on the two engagement plates 325 and be connected to the door 100, so as to fix the base 321 on the door 100.

[0119] 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.

[0120] In actual use, such as Figure 8 and Figure 9 As shown, when the door 100 of the box moves relative to the box body 500 from the position closing the storage space towards the position opening the storage space, since the first rotating shaft fixing seat 312 is fixed on 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. 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.

[0121] Correspondingly, when the door 100 of the box moves relative to the box body 500 from the position opening the storage space towards the position 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.

[0122] Furthermore, in yet another specific implementation manner, such as Figure 10 、 Figure 11 and Figure 12 As 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.

[0123] In some embodiments, the traction assembly includes: a first connecting rod and a second connecting rod. The first end of the first connecting rod is rotatably arranged on the front surface of the box body 500 and is arranged in a dislocation manner with the hinge shaft.

[0124] Among them, the first end of the first connecting rod is rotatably arranged in the installation area. For example, the first end of the first connecting rod is installed in the installation area through a rotating shaft fixing seat. The first end of the second connecting rod is rotatably connected to the second end of the first connecting rod; the second end of the second connecting rod is rotatably arranged on the door 100 and is meshed and connected with the tooth portion on the first slider 322 through a gear arranged at the second end of the second connecting rod.

[0125] It is understandable that the first connecting rod and the second connecting rod are connected by a hinge, and the first connecting rod and the second connecting rod can rotate relative to each other. The first connecting rod can rotate relative to the box body 500, and the second connecting rod can rotate relative to the box door 100.

[0126] When the second end of the second connecting rod makes a circular motion with the cabinet door 100 with the hinge axis as the center, since the first end of the first connecting rod is offset from the hinge axis, the distance between the second end of the second connecting rod and the first end of the first connecting rod changes, while the position of the second end of the second connecting rod relative to the cabinet door 100 remains unchanged, which causes the second end of the second connecting rod to rotate around the cabinet door 100 and drives the second slider 323 to drive the cabinet door 200 to move along the width direction of the cabinet door 100.

[0127] In actual application, during the opening process of the door 100, the door 100 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 100, thereby controlling the second slider 323 to drive the cabinet door 200 to move along the width direction of the door 100 in the direction away from the hinge 400, that is, to move to the left relative to the door 100, 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 100, the door 100 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 is reduced, driving the second end of the second connecting rod to rotate counterclockwise relative to the door 100, thereby controlling the second slider 323 to drive the door 200 to move along the width direction of the door 100 toward the direction close to the hinge 400, that is, to move to the right side relative to the door 100. In this way, it can be ensured that when the door 100 is closed, the door 200 can avoid the door 200 of the cabinet on the side and reset the door 200.

[0128] In an optional embodiment, the first rotating shaft fixing seat 312 is connected to the first sliding block 322 , and the cabinet door 200 can be fixedly connected to the second sliding block 323 .

[0129] 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.

[0130] As an implementation, 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 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. Thus, 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 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 by 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 front surface 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 pass through the through hole and be connected to the front surface of the box body 500 so as to fix the second rotating shaft fixing seat 313 on the front surface 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 pass through the through holes on the first receiving plate 326 and the second receiving plate 327 and be connected to the door 100, so as 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 or the like.

[0136] In actual use, when the box door 100 moves relative to the box body 500 from the position closing the storage space towards the position opening the storage space, since the first rotating shaft fixing seat 312 is fixed to the box door 100 following the hinge seat, during the rotation of the box 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 box 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 box door 100 along the fourth direction. Wherein, the third direction is opposite to the fourth direction, and moreover, both the third direction and the fourth direction are parallel to the width direction of the box door 100.

[0137] Correspondingly, when the box door 100 moves relative to the box body 500 from the position opening the storage space towards the position closing the storage space, during the rotation of the box door 100, the first slider 322 will move along the direction opposite to the third 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 fourth direction on the second guide rail through the connecting member 324. At this time, the cabinet door 200 will move relative to the box door 100 along the direction opposite to the fourth direction.

[0138] Wherein, 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 rails and capable of sliding 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 balls are 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 balls are 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] Wherein, the first connecting member 3241 bypasses one end of the base 321, and the two 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 the two 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 may 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 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.

[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, 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 12 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.

[0145] Specifically, 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 seat. 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.

[0146] 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 rotatably arranged on the second receiving seat respectively. In order to facilitate receiving the second connecting member 3242, a receiving groove extending along its circumferential direction can also be arranged on the outer circumference 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. After that, 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 setting mode, the first roller 328 can support and position the first connecting member 3241, and the second roller 329 can support and position 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 and cause wear and tear, and an effective protection effect can be achieved 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 body 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. 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.
