[0054] In practical applications, in the case where there are multiple door body assemblies 10, the traction components 310 corresponding to each door body assembly 10 are all located on the middle cross beam 501 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 the middle cross beam 501 on the front side of the box body 500.

[0055] 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 refrigerate the storage space.

[0056] 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.

[0057] To facilitate the description of the positional relationship between each component, in this embodiment, as Figure 2As shown, the box body 500 is roughly constructed as a rectangular 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, wherein 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.

[0058] The box body 500 is provided with a storage space inside, and an opening is provided on the side of the box body 500 in the thickness direction, and the opening is connected to the storage space. The box door 100 is connected to the side of the box body 500 in the thickness direction where the opening is provided, and the box door 100 is extended along the width direction of the box body 500. The box door 100 is connected to a hinge 400 on one side of the box body 500 in the width direction, and the box door 100 can be rotatably connected to the box body 500 via the hinge 400, thereby ensuring that the box door 100 can open or close the storage space of the box body 500. Moreover, the side of the box body 500 where the box door 100 is installed is the front side, that is, the box door 100 is installed on the front side of the box body 500.

[0059] The door 100 is generally constructed as a flat plate 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. The height direction of the door 100 is parallel to the vertical direction, and the width direction and the length direction are located in a 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 a hinge 400. For example, Figure 2 As shown, the cabinet door 100 is connected to a hinge 400 on the right side of the cabinet body 500 in the width direction, and the cabinet door 100 can be rotatably connected to the cabinet body 500 via the hinge 400 .

[0060] Moreover, when the door 100 is in a position to close the storage space of the housing 500 , the width direction of the door 100 is parallel to the width direction of the housing 500 , and the thickness direction of the door 100 is parallel to the thickness direction of the housing 500 .

[0061] Furthermore, the cabinet door 200 can be a decorative cabinet door 200. The cabinet door 200 is constructed as a flat structure with a certain thickness. The cabinet door 200 is connected to the outer side of the cabinet door 100 that is away from the cabinet body 500. When the refrigeration equipment is placed together with the cabinet in an embedded manner or directly placed in the cabinet, when the cabinet door 100 is in a closed position, the cabinet door 200 can be flush with the cabinet door 200 of the cabinet, that is, the outer wall surface of the cabinet door 200 that is away from the cabinet door 100 can be flush with the outer wall surface of the cabinet.

[0062] In actual usage scenarios, the outer wall surface of the cabinet door 200 can be selected with the same material and shape as the outer wall surface of the cabinet, and can be attached with the same decoration, so that the refrigeration equipment can be sufficiently coordinated with the cabinet and can ensure aesthetics.

[0063] In one embodiment, as Figure 1 shown, the door body device and the box body 500 are configured to be arranged in the installation space formed between the first cabinet body 510 and the second cabinet body 520; during the process of opening or closing the box door 100, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the box door 100, so that the cabinet door 200 avoids the side walls of the first cabinet body 510 and the second cabinet body 520;

[0064] Alternatively, the door body device and the box body 500 are configured to be arranged in the cabinet body; during the process of opening or closing the box door 100, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the box door 100, so that the cabinet door 200 avoids the side walls of the cabinet body.

[0065] It can be understood that the refrigeration device includes the door body device and the box body 500.

[0066] In practice, as Figure 1 shown, when the refrigeration device with the door body device and the box body 500 is placed between the adjacent first cabinet body 510 and the second cabinet body 520, a cabinet door 200 can be arranged on the outer side of the box door 100 in the door body device, and the cabinet door 200 can move relative to the box door 100 along the width direction of the box door 100. Optionally, when the box door 100 is in the state of closing the storage space of the box body 500, the outer wall surface of the cabinet door 200 facing away from the box door 100 can be flush with the outer wall surfaces of the first cabinet body 510 and the second cabinet body 520, and the outer wall surfaces of the first cabinet body 510 and the second cabinet body 520 and the outer wall surface of the cabinet door 200 facing away from the box door 100 are in the same direction in the thickness direction of the box body 500.

[0067] 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.

[0068] Alternatively, after the refrigeration device is placed in the cabinet body, a cabinet door 200 can be arranged on the outer side of the box door 100 in the door body device, and the cabinet door 200 can move relative to the box door 100. Optionally, when the box door 100 is in the state of closing the storage space of the box body 500, the outer wall surface of the cabinet door 200 facing away from the box door 100 can be flush with the outer wall surface of the cabinet body, and the outer wall surface of the cabinet body and the outer wall surface of the cabinet door 200 facing away from the box door 100 are in the same direction in the thickness direction of the box body 500.

[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, and can also make the cabinet door 200 avoid the side walls of the cabinet body.

[0070] Therefore, after the door device in this embodiment is installed on the cabinet body 500 of the refrigeration equipment, during the rotation of the cabinet door 100 relative to the cabinet body 500, the sliding door assembly 320 can move the cabinet door 200 relative to the cabinet door 100 under the drive of the traction assembly 310, so that when the refrigeration equipment is placed in an embedded manner in the cabinet, while ensuring coordination and aesthetics and not affecting the user's experience, the cabinet door 200 can be prevented from interfering with the cabinet during the process of opening the cabinet door 100.

[0071] In a specific embodiment, Figure 2 As shown, the door body device includes a first box door 110 and a second box door 120, and the first box door 110 and the second box door 120 are spaced apart 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 set on the middle beam 501.

[0072] The traction assembly 310 corresponding to the first door 110 and the traction assembly 310 corresponding to the second door 120 are both arranged close to the first hinge 410 .

[0073] Further, in one embodiment, if Figure 4 As shown, the first hinge 410 includes a first hinge plate 411, a second hinge axis 413 and a third hinge axis 422, the first hinge plate 411 includes a mounting plate 4111 and a connecting plate 4112, the mounting plate 4111 is installed on the front side (middle beam 501) of the box body 500, the connecting plate 4112 is connected to the side of the mounting plate 4111 away from the front side of the box body 500, the connecting plate 4112 is arranged at an angle to the mounting plate 4111, the connecting plate 4112 has a first side and a second side opposite to each other, the first hinge axis 412 is arranged on the first side, the bottom of the first box door 110 is hinged to the first hinge axis 412, the second hinge axis 413 is arranged on the second side, and the top of the second box door 120 is hinged to the second hinge axis 413.

[0074] For example, the first hinge plate 411 can be made of a metal material or a non-metal material with a certain structural strength, and 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. In 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 stamping and folding.

[0075] Two sides of the connecting plate 4112 in the thickness direction are respectively a first side and a second side. The first side is fixedly connected to the first hinge shaft 412 , and the second side is fixedly connected to the second hinge shaft 413 .

[0076] 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 constructed 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. The integral part is inserted into the through holes, and the integral part is fixed in the through holes by welding or threaded connection. The two ends of the integral part in the length direction on the connecting plate 4112 are respectively formed as the third hinge shaft 422 and the fourth hinge shaft 432.

[0077] 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 box door 100. For example, as Figure 2 shown, multiple threaded holes are provided 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 by means of bolts. At this time, the connecting plate 4112 extends towards 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.

[0078] 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 respectively inserted into the hinge holes of their corresponding box doors 100, thereby realizing the installation of the box door 100.

[0079] 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.

[0080] In addition, as Figure 3 shown, the installation area is located on the middle cross beam 501 of the box body 500. The installation area includes a first sub-region A above the mounting plate 4111 and a second sub-region B below the mounting plate 4111. The traction component 310 corresponding to the first box door 110 is arranged in the first sub-region A, and the traction component 310 corresponding to the second box door 120 is arranged in the second sub-region B;

[0081] Among them, the first sub-region 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, and the second side and the fourth side are oppositely arranged. The first side is the top side of the mounting plate 4111, and 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.

[0082] The second sub-region B includes a first side, a second side, a third side, and a fourth side. The first side and the third side are oppositely arranged, and the second side and the fourth side are oppositely arranged. The first side is the bottom side of the mounting plate 4111, and 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.

[0083] In an optional 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] 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.

[0085] Further, in one embodiment, as Figure 5 shown, it further includes a second hinge 420. The second hinge 420 includes a second hinge plate 421 and a third hinge shaft 422. A part of the second hinge plate 421 covers the top wall of the box body 500 and the rest protrudes from the top wall towards the door 100. The third hinge shaft 422 extends downward from the part of the second hinge plate 421 that protrudes from the top wall. The top of the first door 110 is hinged to the third hinge shaft 422.

[0086] Exemplarily, the second hinge plate 421 can be made of a metal or non-metal material with a certain structural strength. The second hinge plate 421 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 third hinge shaft 422 is fixedly arranged on the first protruding part by means of welding or threaded connection, etc.

[0087] 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 second hinge plate 421 is made to fit against the top wall of the box body 500. At the same time, the mounting holes on the first fitting portion are aligned with the threaded holes. Then, the first fitting portion is fixed to the top wall of the box body 500 by means of bolts. At this time, the first fitting portion can cover and fit against the top wall of the box body 500, the first protruding portion can protrude from the top wall towards the first door 110, and moreover, the first hinge shaft 412 can extend downward along the height direction of the box body 500.

[0088] Based on this, when installing the door 100, an articulation hole can be provided in advance at the top of the door 100 corresponding to the second hinge 420. Then, the third hinge shaft 422 is inserted into the articulation hole, thereby enabling the installation of the door 100.

[0089] Furthermore, in one embodiment, as Figure 6 shown, it further includes a third hinge 430. The third hinge 430 includes a third hinge plate 431 and a fourth hinge shaft 432. The third hinge plate 431 includes a support plate 4311 and an extension plate 4312. The support plate 4311 is installed on the front surface (lower cross beam) of the box body 500. The extension plate 4312 is connected to a side of the support plate 4311 facing away from the front surface of the box body 500. The support plate 4311 and the extension plate 4312 are arranged at an angle. The fourth hinge shaft 432 is provided on the top surface of the extension plate 4312 and extends upward. The bottom of the second door 120 is hinged to the fourth hinge shaft 432.

[0090] Similarly, the third hinge plate 431 can also be made of a metal or non-metal material with a certain structural strength. The third hinge plate 431 includes a support plate 4311 and an extension plate 4312 that are connected to each other. The extension plate 4312 is substantially perpendicular to the support plate 4311. The two can be integrally formed by means such as stamping. The support plate 4311 is provided with a plurality of mounting holes. The fourth hinge shaft 432 is fixedly provided on the extension plate 4312 by means such as welding or threaded connection.

[0091] During actual installation, a plurality of threaded holes can be provided in advance at a position on the front surface of the box body 500 and near the bottom. Then, one side in the thickness direction of the support plate 4311 is made to fit against the front surface of the box body 500. Then, the mounting holes on the support plate 4311 are aligned with the threaded holes. Then, the support plate 4311 is fixed to the front surface of the box body 500 by means of bolts. The extension plate 4312 is connected to the other side in the thickness direction of the support plate 4311 and extends towards the direction where the door 100 is located. Moreover, the fourth hinge shaft 432 extends upward along the height direction of the box body 500.

[0092] Based on this, when installing the cabinet door 100, an articulation hole can be set in advance at the bottom of the cabinet door 100 corresponding to the third hinge 430, and then the second articulation shaft 413 is inserted into the articulation hole, thereby enabling the installation of the second cabinet door 120.

[0093] 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 (the middle cross beam 501) 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 sub - area A, the second sub - area B). For example, the second rotating shaft fixing seat 313 is installed in the installation area by screws.

[0094] Exemplarily, the hinge 400 can include a hinge plate and an articulation shaft, and the articulation 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 body 500 by means of structures such as bolts. Threaded holes can be set in the cabinet door 100 in advance. After the hinge plate is fixed to the cabinet body 500, the articulation shaft can be inserted into the articulation hole of the cabinet door 100, thereby realizing the rotational connection of the cabinet door 100 relative to the cabinet body 500.

[0095] 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.

[0096] 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.

[0097] 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 7 and Figure 8 shown, the sliding door assembly 320 includes: a base 321, a first slider 322, a second slider 323, and a connecting member 324.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] As a specific implementation manner, as Figure 7 and Figure 8 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.

[0102] 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 use requirements in different occasions.

[0103] Correspondingly, the drawbar 311 is configured as a long straight bar. 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.

[0104] As an implementation manner, as Figure 8 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, 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.

[0105] Similarly, as Figure 7 and Figure 8 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, and thus is rotatably connected to the second rotating shaft fixing seat 313.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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 - fitting structures.

[0110] During actual use, as Figure 7 and Figure 8 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 box 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.

[0111] 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 box 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.

[0112] In an embodiment of the present utility model, as Figure 9As shown in the figure, the sliding door assembly 320 includes: a base 321, rolling elements 328, a first slider 322, a second slider 323, and a connecting member 324. 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 sleeved on the first guide rail 3211, and the first slider 322 is slidably disposed on the first guide rail 3211 through the rolling elements 328. The second slider 323 is sleeved on the second guide rail 3212, and the second slider 323 is slidably disposed on the second guide rail 3212 through the rolling elements 328. 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.

[0113] 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, external bolt holes 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.

[0114] 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 axis.

[0115] Among them, the first end of the first connecting rod is rotatably disposed 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 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.

[0116] 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.

[0117] When the second end of the second connecting rod makes a circular motion around the hinge axis with the cabinet door 100, since the first end of the first connecting rod is disposed 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, and 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 along the width direction of the cabinet door 100.

[0118] In practical applications, during the opening process of the cabinet door 100, the cabinet door 100 drives the second end of the second link to rotate relative to the hinge axis. Based on the misaligned arrangement of the first end of the first link and the hinge axis, the distance between the first end of the first link and the second end of the second link increases, driving the second end of the second link to rotate clockwise relative to the cabinet door 100. Further, it controls the second slider 323 to drive the cabinet door 200 to move in the width direction of the cabinet door 100 away from the hinge 400, that is, move to the left relative to the cabinet door 100. In this way, it can avoid interference between the cabinet door 200 and the cabinet doors of the side cabinets; during the closing process of the cabinet door 100, the cabinet door 100 drives the second end of the second link to rotate relative to the hinge axis. Based on the misaligned arrangement of the first end of the first link and the hinge axis, the distance between the first end of the first link and the second end of the second link decreases, driving the second end of the second link to rotate counterclockwise relative to the cabinet door 100. Further, it controls the second slider 323 to drive the cabinet door 200 to move in the width direction of the cabinet door 100 towards the hinge 400, that is, move to the right relative to the cabinet door 100. In this way, it can ensure that the cabinet door 200 can avoid the cabinet doors of the side cabinets when the cabinet door 100 is closed and reset the cabinet door 200.

[0119] Among them, 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 that are adapted to the corresponding guide rails and can slide along the corresponding guide rails; in addition, the sliding fit between the first slider 322 and the first guide rail should at least include the case where there are balls arranged between the first slider 322 and the first guide rail, and the sliding fit between the second slider 323 and the second guide rail should at least include the case where there are balls arranged between the second slider 323 and the second guide rail.

[0120] Specifically, during the process of the cabinet door 100 rotating outward and opening towards the outside of the cabinet body 500, the cabinet door 100 drives the first slider 322 to slide towards the direction close to the first hinge 410. At the same time, the first slider 322 drives the second slider 323 to slide in the opposite direction (that is, away from the first hinge 410) through the connecting member 324, so as to avoid interference between the cabinet door 200 and the external obstacles. During the process of the cabinet door 100 rotating and closing towards one side of the cabinet body 500, the cabinet door 100 drives the first slider 322 to slide away from the first hinge 410. At the same time, the first slider 322 drives the second slider 323 to slide in the opposite direction (that is, close to the first hinge 410) through the connecting member 324, so as to avoid interference between the closed cabinet door 200 and the obstacles.

[0121] At the same time, by respectively arranging rolling elements 328 between the first slider 322 and the first guide rail 3211, and between the second slider 323 and the second guide rail 3212, the sliding friction between the slider and the guide rail is converted into rolling friction, making the sliding of the first slider 322 and the second slider 323 smoother, and thus making the sliding of the cabinet door 200 smoother.

[0122] According to the sliding door mechanism 300 of the utility model, a first guide rail 3211 and a second guide rail 3212 are arranged on both sides of the base 321, and a first slider 322 and a second slider 323 are slidably arranged on the first guide rail 3211 and the second guide rail 3212, respectively. The first slider 322 and the second slider 323 can slide synchronously along the guide rails driven by the connecting member 324, and the sliding directions are opposite. One of the first slider 322 and the second slider 323 is drivingly connected to the box door 100 or the box body 500. , and the other is connected to the cabinet door 200 arranged on the outside of the cabinet door 100, so that when the cabinet door 100 rotates, the two sliders slide relative to each other to drive the cabinet door 200 to slide relative to the cabinet door 100, so that the cabinet door 200 can avoid obstacles on both sides during the process of turning the cabinet door 100. At the same time, by arranging a rolling body 328 between the slider and the guide rail, it is helpful to reduce the friction between the slider and the guide rail, so that the sliding of the first slider 322 and the second slider 323 is smoother, thereby making the sliding of the cabinet door 200 also smoother.

[0123] In one embodiment of the present invention, a slot is provided on the second sliding block 323 to facilitate plugging with a connector on the cabinet door 200 .

[0124] like Figure 9 and Figure 10 As shown, the sliding door mechanism 300 further includes a traction assembly 310, which 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 first sliding block 322, and the second rotating shaft fixing seat 313 is used to be connected to the middle cross beam 501. 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.

[0125] Specifically, one end of the traction rod 311 is rotatably connected to the first rotation shaft fixing seat 312 via a pin, and the other end of the traction rod 311 is rotatably connected to the second rotation shaft fixing seat 313 via another pin.

[0126] In one embodiment of the present invention, Figure 9 and Figure 10 As shown, the connecting member 324 includes: a first connecting member 3241 and a second connecting member 3242. The first connecting member 3241 bypasses one end of the base 321, and both ends are respectively connected to one end of the first slider 322 and the second slider 323; the second connecting member 3242 bypasses the other end of the base 321, and both ends are respectively connected to the other ends of the first slider 322 and the second slider 323.
