[0053] As Figure 2 shown, the door body device of the embodiments of the present utility model includes a plurality of door body components 10, and the plurality of door body components 10 are arranged side by side in the height direction of the box body 500. Each door body component 10 includes: a box door 100, a cabinet door 200, and a sliding door mechanism 300.

[0054] 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 arranged on the outer side of the box door 100; the sliding door mechanism 300 includes a connected traction component 310 and a sliding door component 320. The traction component 310 is arranged on the front of the box body 500, and the sliding door component 320 is arranged on the box door 100 and connected to the cabinet door 200. The traction component 310 is configured to drive the sliding door component 320 to act during the opening or closing process of the box door 100, thereby driving the cabinet door 200 to move relative to the width direction of the box door 100.

[0056] In practical applications, in the case where there are multiple door body assemblies 10, the traction component 310 corresponding to one door body assembly 10 is located on the middle cross beam 501 of the box body 500, and the traction component 310 corresponding to another door body assembly 10 is located on the lower cross beam 502 of the box body 500. That is to say, each door body assembly 10 is correspondingly provided with a sliding door mechanism 300, and the multiple traction components 310 corresponding to the multiple door body assemblies 10 are respectively located at different positions on the front of the box body 500.

[0057] 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 items such as vegetables and fruits that need to be refrigerated or frozen can be placed in the storage space. Optionally, a refrigeration device and the like are also arranged in the box body 500 of the refrigeration equipment, and the refrigeration device can perform refrigeration processing on the storage space.

[0058] In this embodiment, the box door 100 in the door body device is rotatably arranged on the box body 500 of the refrigeration equipment through a hinge 400. The box door 100 can be used to open or close the storage space in the box body 500. When the box door 100 is in the closed position of closing the storage space, the storage space is in a closed state, and the items in the storage space can be refrigerated. When the box door 100 is in the open position of opening the storage space, the storage space is in an open state, and the user can take out the items in the storage space.

[0059] To facilitate the description of the positional relationship between each component, in this embodiment, as Figure 2As shown, the box body 500 is generally constructed as a cuboid structure with a certain height. The box body 500 can be placed on a horizontal plane. The box 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 box 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.

[0060] A storage space is provided inside the box body 500. An opening is provided on the side of the box body 500 in the thickness direction, and this opening communicates with the storage space. The door 100 is connected to the side of the box body 500 in the thickness direction where this opening is provided. The door 100 extends along the width direction of the box body 500. A hinge 400 is connected to one side of the door 100 in the width direction of the box body 500. The door 100 can be rotatably connected to the box body 500 via this hinge 400, so as to ensure that the door 100 can open or close the storage space of the box body 500. Moreover, the side of the box body 500 where the door 100 is installed is the front side, that is, the door 100 is installed on the front side of the box body 500.

[0061] The door 100 is generally constructed as a flat plate-like structure with a certain thickness. The door 100 has a height direction, a width direction, and a thickness direction that are perpendicular to each other. Among them, the height direction of the door 100 is parallel to the vertical direction, and the width direction and the length direction are located in the horizontal plane and are perpendicular to each other. One side of the door 100 in the width direction can be rotatably connected to the box body 500 via the hinge 400. For example, as Figure 2 shown, the door 100 is connected to the hinge 400 on the right side of the box body 500 in the width direction. The door 100 can be rotatably connected to the box body 500 via this hinge 400.

[0062] Moreover, when the door 100 is in the position of closing the storage space of the box body 500, the width direction of the door 100 is parallel to the width direction of the box body 500, and the thickness direction of the door 100 is parallel to the thickness direction of the box body 500.

[0063] Furthermore, the cabinet door 200 can be a decorative cabinet board. The cabinet door 200 is constructed as a flat plate-like structure with a certain thickness. The cabinet door 200 is connected to the outer side of the door 100 facing away from the 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 door 100 is in the closed position, the cabinet door 200 can be flush with the cabinet board 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.

[0064] 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 can ensure the aesthetics.

[0065] In one embodiment, as Figure 1 shown, the door device and the box body 500 are configured to be arranged in the installation space formed between the first cabinet body 510 and the second cabinet body 520; during the process of opening or closing the box door 100, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the box door 100, so that the cabinet door 200 avoids the side walls of the first cabinet body 510 and the second cabinet body 520;

[0066] Alternatively, the door device and the box body 500 are configured to be arranged in the cabinet; 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.

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

[0068] In practice, as Figure 1 shown, when the refrigeration device with the door device and the box body 500 is placed between the adjacent first cabinet body 510 and the second cabinet body 520, a cabinet door 200 can be arranged on the outer side of the box door 100 in the door device, and the cabinet door 200 can move relative to the box door 100 along the width direction of the box door 100. Optionally, when the box door 100 is in the state of closing the storage space of the box body 500, the outer wall surface of the cabinet door 200 facing away from the box door 100 can be flush with the outer wall surfaces of the first cabinet body 510 and the second cabinet body 520, and the outer wall surfaces of the first cabinet body 510 and the second cabinet body 520 and the outer wall surface of the cabinet door 200 facing away from the box door 100 are in the same direction in the thickness direction of the box body 500.

[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] Alternatively, after the refrigeration device is placed in the cabinet, a cabinet door 200 can be arranged 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.

[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.

[0072] Thus, after the door device in this embodiment is installed on the cabinet 500 of the refrigeration device, during the rotation of the cabinet door 100 relative to the cabinet 500, the sliding door assembly 320 can drive the cabinet door 200 to move relative to the cabinet door 100 under the drive of the traction assembly 310. Therefore, when the refrigeration device is placed in the cabinet in an embedded manner, it can avoid interference between the cabinet door 200 and the cabinet during the opening of the cabinet door 100 while ensuring coordination, aesthetics, and not affecting the user experience.

[0073] In a specific embodiment, as Figure 2 shown, the door device includes a first cabinet door 110 and a second cabinet door 120. The first cabinet door 110 and the second cabinet door 120 are arranged at intervals along the height direction of the cabinet 500. At this time, the bottom of the first cabinet door 110 is rotatably connected to the cabinet 500 through a first hinge 410 provided on the middle cross beam 501, and the bottom of the second cabinet door 120 is rotatably connected to the cabinet 500 through a second hinge 420 provided on the lower cross beam 502 of the cabinet 500.

[0074] Among them, the traction assembly 310 corresponding to the first cabinet door 110 is arranged close to the first hinge 410, and the traction assembly 310 corresponding to the second cabinet door 120 is arranged close to the second hinge 420.

[0075] Further, in an embodiment, as Figure 5 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 (middle cross beam 501) of the cabinet 500, and the connecting plate 4112 is connected to the side of the mounting plate 4111 facing away from the front surface of the cabinet 500. The connecting plate 4112 is arranged at an angle with the mounting plate 4111. The connecting plate 4112 has opposite first and second sides. The first hinge shaft 412 is arranged on the first side, and the bottom of the first cabinet door 110 is hinged to the first hinge shaft 412. The second hinge shaft 413 is arranged on the second side, and the top of the second cabinet door 120 is hinged to the second hinge shaft 413.

[0076] 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 connected to each other. The connecting plate 4112 is substantially perpendicular to the mounting plate 4111, and 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 plate, and then, the connecting plate 4112 can be bent relative to the mounting plate 4111 by means of stamping and folding.

[0077] On both sides of the connecting plate 4112 in the thickness direction are a first side and a second side respectively. A first hinge shaft 412 is fixedly connected to the first side, and a second hinge shaft 413 is fixedly connected to the second side.

[0078] 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. Or, the first hinge shaft 412 and the second hinge shaft 413 can be configured as an integral part in the shape of a long bar. The connecting plate 4112 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 4112 are respectively formed as a third hinge shaft 422 and a fourth hinge shaft 432.

[0079] 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 Figure 2 shown, 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 4111 of the first hinge plate 411 are aligned with the positions of the threaded holes, and then the mounting plate 4111 is fixed to the front surface of the box body 500 with the help of bolts. At this time, the connecting plate 4112 extends towards the direction of the box door 100. At the same time, the first hinge shaft 412 extends upwards along the height direction of the box body 500, and the second hinge shaft 413 extends downwards along the height direction of the box body 500.

[0080] Based on this, when installing the box door 100, a hinge hole can be set in advance at the bottom of the first box door 110 corresponding to the first hinge shaft 412, and, a hinge hole can be set 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 respectively inserted into the hinge holes of their corresponding box doors 100. Thus, the installation of the box door 100 can be realized.

[0081] In this way, the traction assembly 310 on the middle cross beam 501 of the box body 500 is arranged close to the mounting plate 4111.

[0082] In addition, as Figure 3As shown, the first installation area A is located on the middle cross beam 501 of the box body 500. The first installation area A is located above the installation plate 4111. The first installation area A includes a first side, a second side, a third side, and a fourth side. The first side and the third side are oppositely arranged. The second side and the fourth side are oppositely arranged. The first side is the top side of the installation plate 4111. The second side is located in the plane of the side surface 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.

[0083] 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.

[0084] Furthermore, 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 (lower cross beam 502) of the box body 500. The extension plate 4212 is connected to the side of the support plate 4211 facing away from the front surface of the box body 500. The support plate 4211 and the extension plate 4212 are arranged at an angle. The third hinge shaft 422 is provided 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.

[0085] 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 the like. The support plate 4211 is provided with a plurality of mounting holes. The third hinge shaft 422 is fixedly provided on the extension plate 4212 by welding or threaded connection or the like.

[0086] During actual installation, a plurality of threaded holes can be set in advance at a position near the bottom on the front surface of the box body 500. Then, let one side of the support plate 4211 in the thickness direction fit to the front surface of the box body 500. Then, let the mounting holes on the support plate 4211 correspond to the positions of the threaded holes. Then, fix the support plate 4211 to the front surface of the box body 500 with bolts. The extension plate 4212 is connected to the other side of the support plate 4211 in the thickness direction and extends towards the direction of the door 100. Moreover, the second hinge shaft 413 extends upward along the height direction of the box body 500.

[0087] Based on this, when installing the cabinet door 100, a hinge hole can be set in advance at the bottom of the cabinet door 100 corresponding to the second hinge 420, and then the second hinge shaft 413 is inserted into the hinge hole, thereby realizing the installation of the cabinet door 100.

[0088] In this way, the traction assembly 310 on the lower cross beam 502 of the cabinet body 500 is arranged close to the second hinge plate 421. As Figure 4 shown, the traction assembly 310 is arranged in the second installation area B. The second installation area B is located on the lower cross beam 502 of the cabinet body 500, above the support plate 4211. The second installation area B includes a first side, a second side, a third side, and a fourth side. The first side and the third side are arranged opposite to each other, the second side and the fourth side are arranged opposite to each other. The first side is the top edge of the support plate 4211, and the second side is located in the plane where the side surface of the cabinet body 500 is located. In the height direction of the cabinet body 500, a third distance is left between the third side and the first side; in the width direction of the cabinet body 500, a fourth distance is left between the fourth side and the second side.

[0089] In an alternative embodiment, the third distance is greater than zero and less than or equal to 60 mm, and the fourth distance is greater than zero and less than or equal to 100 mm.

[0090] For example, the fourth distance is 10 mm, 20 mm, 50 mm, 70 mm, 100 mm, and the third distance is 10 mm, 20 mm, 50 mm, 60 mm.

[0091] Furthermore, 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 cabinet body 500 and the rest protrudes from the top wall towards the corresponding cabinet door 100. The fourth hinge shaft 432 extends downward from the part of the third hinge plate 431 that protrudes from the top wall, and the top of the first cabinet door 110 is hinged to the fourth hinge shaft 432.

[0092] 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 part and a first protruding part that are connected to each other. The first fitting part is provided with a plurality of mounting holes, and the first hinge shaft 412 is fixedly arranged on the first protruding part by means of welding or threaded connection, etc.

[0093] During actual installation, a plurality of threaded holes can be provided in advance on the top wall of the cabinet 500. Then, the first fitting portion of the first hinge plate 411 is fitted to the top wall of the cabinet 500. At the same time, the mounting holes on the first fitting portion are aligned with the threaded holes. Then, the first fitting portion is fixed to the top wall of the cabinet 500 by means of bolts. At this time, the first fitting portion can cover and fit to the top wall of the cabinet 500, the first protruding portion can protrude from the top wall towards the door 100, and moreover, the first hinge shaft 412 can extend downward along the height direction of the cabinet 500.

[0094] Based on this, when installing the door 100, a hinge hole can be provided in advance at the top of the door 100 corresponding to the third hinge 430. Then, the fourth hinge shaft 432 is inserted into the hinge hole. Thus, the installation of the door 100 can be achieved.

[0095] In a specific embodiment, as Figure 2 shown, the cabinet 500 is provided with two storage spaces at intervals along its height direction. A third hinge 430 is provided at the top of the cabinet 500, a second hinge 420 is provided at the bottom of the cabinet 500, and a first hinge 410 is provided in the middle of the cabinet 500 and approximately at a position between the two storage spaces. The door device includes two doors 100, namely a first door 110 and a second door 120. The first door 110 and the second door 120 are provided at intervals along the height direction of the cabinet 500. The first door 110 and the second door 120 respectively correspond to the two storage spaces of the cabinet 500. During installation, the top of the first door 110 is hinged to the fourth hinge shaft 432 of the third hinge 430, the bottom of the first door 110 is hinged to the first hinge shaft 412 of the first hinge 410, the top of the second door 120 is hinged to the second hinge shaft 413 of the first hinge 410, and the bottom of the second door 120 is hinged to the third hinge shaft 422 of the second hinge 420.

[0096] Thus, through the above setting method, the first door 110 and the second door 120 can be rotatably connected to the cabinet 500.

[0097] 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 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.

[0098] 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 cabinet 500 by means of structures such as bolts. Threaded holes can be provided in the cabinet door 100 in advance. After the hinge plate is fixed to the cabinet 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 cabinet 500.

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

[0100] During actual use, when the cabinet door 100 rotates relative to the cabinet 500 between the positions of opening or closing the storage space, 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.

[0101] Further, 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.

[0102] Specifically, a first guide rail 3211 is formed on one side of the base 321, and a second guide rail 3212 is formed on the other side; the first slider 322 is slidably disposed on the first guide rail 3211, and the first rotating shaft fixing seat 312 is connected to the first slider 322; the second slider 323 is slidably disposed on the second guide rail 3212 and is connected to the cabinet door 200; both ends of the connecting member 324 are respectively connected to the first slider 322 and the second slider 323.

[0103] During the opening or closing process of the box door 100, the traction rod 311 drives the first slider 322 to move on the first guide rail 3211, and the first slider 322 drives the second slider 323 to move in the opposite direction on the second guide rail 3212 through the connecting member 324.

[0104] Exemplarily, the base 321 has the first guide rail 3211 and the second guide rail 3212 arranged side by side and at intervals. The first slider 322 is disposed on the first guide rail 3211, and the first slider 322 can slide along the length direction of the first guide rail 3211. The second slider 323 is disposed on the second guide rail 3212, and the second slider 323 can slide along the length direction of the second guide rail 3212. 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 3211, the first slider 322 can pull the second slider 323 to move on the second guide rail 3212 through the connecting member 324, and the moving direction of the second slider 323 is opposite to the moving direction of the first slider 322.

[0105] As a specific implementation manner, as Figure 8 and Figure 9 shown, the opposite 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 3211, and the U-shaped groove on the second side is the second guide rail 3212. The first guide rail 3211 and the second guide rail 3212 extend along the length direction of the base 321. The first slider 322 is slidably disposed in the first guide rail 3211, and the second slider 323 is slidably disposed in the second guide rail 3212. Moreover, the first rotating shaft fixing seat 312 is connected to the first slider 322, and the cabinet door 200 can be fixedly connected to the second slider 323.

[0106] Considering the requirements in actual applications, limit structures can also be provided at the ends on both sides of the first guide rail 3211 and the second guide rail 3212. 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.

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

[0108] As an implementation, as Figure 9 shown, the first rotating shaft fixing seat 312 includes a first vertical plate and a first horizontal plate. The first vertical plate and the first horizontal plate are connected to each other and form an L-shaped structure. The first horizontal plate is provided with a shaft hole, and the first rotating shaft is inserted into the shaft hole. One end of the drawbar 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 such as welding.

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

[0110] To ensure that the first slider 322 and the second slider 323 can move synchronously and in opposite directions, exemplarily, the connecting member 324 includes a first connecting member 3241 and a second connecting member 3242, and the first connecting member 3241 and the second connecting member 3242 are configured as flexible ropes. In the length direction of the base 321, the first connecting member 3241 bypasses the end of the base 321, and its two ends respectively enter the first guide rail 3211 and the second guide rail 3212, 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 3211 and the second guide rail 3212, and are respectively connected to the first slider 322 and the second slider 323. At this time, the two ends of the first connecting member 3241 are respectively connected to the two ends of the second connecting member 3242 via the first slider 322 and the second slider 323, and form a substantially annular structure.

[0111] During actual installation, after the hinge plate is fixedly installed on the box body 500, the second rotating shaft fixing seat 313 can be fixed on the front surface of the box body 500 by means of structures such as bolts.

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

[0113] After that, the cabinet door 200 is fixed to the second slider 323. For example, the cabinet door 200 can be fixedly connected to the second slider 323 by means of bolts or snap - fit structures.

[0114] During actual use, as Figure 8 and Figure 9 shown, when the door 100 moves from the position of closing the storage space towards the position of opening the storage space relative to the cabinet body 500, 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 3211. Correspondingly, the first slider 322 will pull the second slider 323 to move along the second direction on the second guide rail 3212 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.

[0115] Correspondingly, when the door 100 moves from the position of opening the storage space towards the position of closing the storage space relative to the cabinet body 500, 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 3211. 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 3212 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.

[0116] In another embodiment of the present utility model, as Figure 10 and Figure 11As shown, the sliding door assembly 320 includes a base 321, a first slider 322, a second slider 323, a guide member 328, and a connecting member 324. On one side of the base 321, a first guide rail 3211 is formed, and on the other side, a second guide rail 3212 is formed; the first slider 322 is slidably disposed on the first guide rail 3211; the second slider 323 is slidably disposed on the second guide rail 3212; the guide member 328 is disposed on the base 321, the connecting member 324 is wound around the guide member 328, and the two ends of the connecting member 324 are respectively connected to the first slider 322 and the second slider 323; when the first slider 322 moves on the first guide rail 3211, the first slider 322 drives the second slider 323 to move in the opposite direction on the second guide rail 3212 through the connecting member 324.

[0117] The base 321 can be fixed to the cabinet door 100 by means of structures such as bolts. Exemplarily, a first receiving plate 326 and a second receiving plate 327 are respectively disposed on both sides in the length direction of the base 321, and through holes are respectively disposed 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 cabinet door 100, thereby fixing the base 321 to the cabinet door 100.

[0118] 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 disposed on the front surface of the box body 500 and is disposed offset from the hinge shaft.

[0119] Wherein, the first end of the first connecting rod is rotatably disposed within the installation area. For example, the first end of the first connecting rod is installed within 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 disposed on the cabinet door 100 and is meshed and connected to the tooth portion on the first slider 322 through a gear disposed at the second end of the second connecting rod.

[0120] It can be understood that the first connecting rod and the second connecting rod are connected by a hinge, 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 cabinet door 100.

[0121] When the second end of the second connecting rod makes a circular motion around the hinge shaft with the cabinet door 100 as the center, due to the offset setting of the first end of the first connecting rod from the hinge shaft, 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. As a result, the second end of the second connecting rod rotates around the cabinet door 100 and drives the second slider 323 to drive the cabinet door 200 to move in the width direction of the cabinet door 100.

[0122] 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.

[0123] In an optional embodiment, the first rotating shaft fixing seat 312 is connected to the first sliding block 322 , and the second sliding block 323 is connected to the cabinet door 200 .

[0124] Specifically, the first guide rail 3211 is located at the top of the base 321, providing a sliding track for the first slider 322. The second guide rail 3212 is located at the bottom of the base 321, parallel to or at a certain angle to the first guide rail 3211, providing a sliding track for the second slider 323. The connecting member 324 can be a connecting member such as a traction rope, a transmission belt, etc. The connecting member 324 is wound around the guide member 328, and the two ends of the connecting member 324 are respectively connected to the first slider 322 and the second slider 323.

[0125] When the first slider 322 is driven to move on the first guide rail 3211, since the two ends of the connecting member 324 are respectively fixed to the first slider 322 and the second slider 323, and the connecting member 324 is wound around the guide member 328, by reasonably setting the extension direction of the connecting member 324, the connecting member 324 will drive the second slider 323 to move in the opposite direction on the second guide rail 3212. This synchronous reverse movement feature enables the cabinet panel to slide relative to the width direction of the cabinet 500 when the first slider 322 is transmission-connected to the box body 500 and the second slider 323 is connected to the cabinet panel.

[0126] In this way, by respectively arranging the first slider 322 and the second slider 323 on the first guide rail 3211 and the second guide rail 3212, and connecting the first slider 322 and the second slider 323 by means of the connecting member 324 wound around the guiding member 328, when the first slider 322 moves, it can drive the second slider 323 to move in the opposite direction. Thus, when the first slider 322 is in transmission connection with the box body 500 and the second slider 323 is connected to the cabinet board, the sliding door mechanism 300 can be used to drive the cabinet board to slide relative to the width direction of the box door 100, so that the cabinet board can avoid obstacles such as side walls and objects during the closing or opening process of the box door 100, so as to meet the usage requirements of users in different scenarios.

[0127] In some embodiments, the connecting member 324 is a rope, and the guiding member 328 is a support shaft; the support shaft is connected to the base 321, and the support shaft is located between the first guide rail 3211 and the second guide rail 3212.

[0128] In this embodiment, the guiding member 328 is specifically embodied as a support shaft. The support shaft is firmly connected to the base 321 and is generally located at the central position between the first guide rail 3211 and the second guide rail 3212 (the actual position can be adjusted according to design requirements). The main function of the support shaft is to provide a stable fulcrum for the rope to wind around it, so as to guide the movement direction of the rope and ensure that the first slider 322 and the second slider 323 can move synchronously and in opposite directions along a predetermined track. The two ends of the rope are respectively connected to the first slider 322 and the second slider 323. As a flexible but strong connecting material, the rope is very suitable for transmitting the movement and force between the two sliders. The rope is wound around the support shaft. This winding method enables the rope to slide along the support shaft and stretch or contract accordingly when the first slider 322 moves on the first guide rail 3211, so as to drive the second slider 323 to move in the opposite direction on the second guide rail 3212. The winding method of the rope may adopt a single loop, multiple loops or other complex winding modes according to actual needs to achieve the best transmission effect. At the same time, fixing points or clamps for connecting the rope are respectively provided on the first slider 322 and the second slider 323. These fixing points or clamps should be designed to be strong enough to withstand the tensile force and shear force transmitted by the rope to ensure the stable movement of the slider.

[0129] Based on the above embodiments, in some embodiments, there are two ropes, namely the first rope and the second rope; there are two support shafts, namely the first support shaft and the second support shaft. The first support shaft is connected to one side of the base 321, the second support shaft is connected to the other side of the base 321, the first rope is wound around the first support shaft, and the two ends of the first rope are respectively connected to one side of the first slider 322 and one side of the second slider 323, the second rope is wound around the second support shaft, and the two ends of the second rope are respectively connected to the other side of the first slider 322 and the other side of the second slider 323.

[0130] When the first slider 322 moves on the first guide rail 3211, it pulls the second slider 323 to move in the opposite direction on the second guide rail 3212 through the first rope. Similarly, the two ends of the second rope are respectively connected to the other side of the first slider 322 and the other side of the second slider 323, providing another independent path for the reverse movement between the two.

[0131] Since the two ropes are respectively wound around two support shafts and independently connect the two sides of the first slider 322 and the second slider 323, they can transmit force and motion more evenly. This design helps to improve the problem of asynchronous movement of the sliders caused by uneven rope tension or deviation of the support shaft position.

[0132] In some embodiments, when a single rope is used to connect the first slider 322 and the second slider 323, according to the position of the support shaft setting, after the first slider 322 moves a certain distance on the first guide rail 3211, the second slider 323 will only move a short distance, and the two will not move synchronously throughout the process.

[0133] To ensure that the first slider 322 and the second slider 323 can move synchronously throughout the reverse movement, one end of the first rope is connected to the front end of one side of the first slider 322, the other end of the first rope is connected to the front end of one side of the second slider 323, one end of the second rope is connected to the rear end of the other side of the first slider 322, and the other end of the second rope is connected to the rear end of the other side of the second slider 323.

[0134] Specifically, in this embodiment, the first rope is wound around the first support shaft on the front side of the base 321. One end of the first rope is connected to a position slightly to the left of the front side of the first slider 322, and the other end of the first rope is connected to a position slightly to the left of the front side of the second slider 323. Correspondingly, the second rope is wound around the second support shaft on the rear side of the base 321. One end of the second rope is connected to a position slightly to the right of the rear side of the first slider 322, and the other end of the second rope is connected to a position slightly to the right of the rear side of the second slider 323.

[0135] Through the above connection method, when the first slider 322 moves to the right on the first guide rail 3211, although it is difficult for the first rope to pull the second slider 323 to move, the second rope can pull the second slider 323 to move in the opposite direction (to the left) on the second guide rail 3212. When the first slider 322 moves to the left, the first rope can pull the second slider 323 to move in the opposite direction (to the right).

[0136] 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 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 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.

[0137] 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.

[0138] Finally, it should be noted that: the parallelism and perpendicularity referred to in the embodiments of the present invention should not be strictly limited in the geometric sense. At least manufacturing and installation errors should be considered. For example, errors of plus or minus 10° should be within the scope protected by the embodiments of the present invention. In addition, the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
