That is to say, each door body assembly 10 is correspondingly provided with two sliding door mechanisms 300, and the two traction components 310 are respectively located at different positions on the front of the cabinet 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 cabinet body 500, and the cabinet 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 cabinet 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 body device is rotatably arranged on the cabinet body 500 of the refrigeration equipment 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 of closing the storage space, the storage space is in a closed state, and the items in the storage space can be refrigerated. When the cabinet door 100 is in the open position of opening the storage space, the storage space is in an open state, and the user can take out the items in the storage space.

[0065] For the convenience of expressing 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.

[0066] A storage space is provided inside the box body 500, and an opening is provided on the side of the box body 500 in the thickness direction, which 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. 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. 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.

[0067] Moreover, the side of the box body 500 on which 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 .

[0068] 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 .

[0069] 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 .

[0070] Furthermore, the cabinet door 200 can be a decorative door panel. 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 door panel 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.

[0071] In an 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 aesthetics.

[0072] After the door body device in this embodiment is installed on the cabinet body 500 of the refrigeration device, when the box door 100 rotates relative to the cabinet body 500 to open or close the storage space of the cabinet body 500, the sliding door mechanism 300 can drive the cabinet door 200 to move relative to the box door 100 in the width direction of the box door 100. Thus, when the refrigeration device is placed in the cabinet in an embedded manner, interference between the cabinet door 200 and the cabinet can be avoided during the process of opening the box door 100 while ensuring coordination, aesthetics, and without affecting the user experience.

[0073] 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 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.

[0074] Alternatively, the door body device and the cabinet 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 walls of the cabinet.

[0075] It can be understood that the refrigeration device includes a door body device and a cabinet body 500.

[0076] 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 provided 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 in 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 cabinet 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 cabinet body 500.

[0077] At this time, during the process of the box door 100 rotating 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 avoids the side walls of the first cabinet body 510 and the second cabinet body 520.

[0078] 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 cabinet 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 cabinet body 500.

[0079] At this time, during the rotation of the box door 100 relative to the cabinet body 500, the sliding door mechanism 300 can drive the cabinet door 200 to move, and can also make the cabinet door 200 avoid the side wall of the cabinet body.

[0080] Thus, when the door device in this embodiment is installed on the cabinet body 500 of the refrigeration device, during the rotation of the box door 100 relative to the cabinet 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 user experience and ensuring coordination and aesthetics, the interference between the cabinet door 200 and the cabinet can be avoided during the opening of the box door 100.

[0081] 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 cabinet body 500. At this time, the top of the first box door 110 is rotatably connected to the cabinet body 500 through a first hinge 410 provided on the top wall of the cabinet body 500, the bottom of the first box door 110 and the top of the second box door 120 are rotatably connected to the cabinet body 500 through a second hinge 420 provided on the middle cross beam 502, and the bottom of the second box door 120 is rotatably connected to the cabinet body 500 through a third hinge 430 provided on the lower cross beam 503 of the cabinet body 500.

[0082] Correspondingly, as Figure 3 shown, the traction assembly 310 located on the upper cross beam 501 of the cabinet body 500 is arranged close to the first hinge 410. Under the action of the traction assembly 310, the sliding door assembly 320 can drive the cabinet door 200 corresponding to the first box door 110 to move in the width direction of the first box door 110. As Figure 4 shown, the traction assembly 310 located on the middle cross beam 502 of the cabinet body 500 is arranged close to the second hinge 420. Under the action of the traction assembly 310, the sliding door assembly 320 can drive the cabinet door 200 corresponding to the first box door 110 to move in the width direction of the first box door 110. It can be seen that two sliding door mechanisms 300 are provided on the first box door 110.

[0083] As Figure 4 shown, the traction assembly 310 located on the middle cross beam 502 of the box body 500 is disposed close to the second hinge 420. Under the action of the traction assembly 310, the sliding door assembly 320 can drive the cabinet door 200 corresponding to the second box door 120 to move relative to the width direction of the second box door 120. As Figure 5 shown, the traction assembly 310 located on the lower cross beam 503 of the box body 500 is disposed close to the third hinge 430. Under the action of the traction assembly 310, the sliding door assembly 320 can drive the cabinet door 200 corresponding to the second box door 120 to move relative to the width direction of the second box door 120. Thus, it can be known that two sliding door mechanisms 300 are provided on the second box door 120.

[0084] Further, in one embodiment, as Figure 6 shown, the first hinge 410 includes a first hinge plate 411 and a first hinge shaft 412. A part of the first hinge plate 411 covers the top wall of the box body 500 and the rest projects from the top wall towards the first box door 110. The first hinge shaft 412 extends downward from the part of the first hinge plate 411 that projects from the top wall, and the top of the first box door 110 is hinged to the first hinge shaft 412.

[0085] Exemplarily, the first hinge plate 411 and the first hinge shaft 412 can be made of a metal or non-metal material with a certain structural strength. The first hinge plate 411 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.

[0086] During actual installation, a plurality of threaded holes can be provided in advance on the top wall of the box body 500. Then, the first fitting portion of the first hinge plate 411 is made to fit against the top wall of the box body 500, 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 against the top wall of the box body 500, the first protruding portion can project 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.

[0087] Based on this, when installing the box door 100, a hinge hole can be provided in advance at the top of the box door 100 corresponding to the first hinge 410. Then, the first hinge shaft 412 is inserted into the hinge hole, and thus, the installation of the box door 100 can be achieved.

[0088] In this way, the traction assembly 310 located on the upper cross beam 501 of the box body 500 is disposed close to the first hinge plate 411.

[0089] As Figure 3As shown, the traction assembly 310 corresponding to the first cabinet door 110 is disposed within the first installation area A, and the first installation area A is located on the upper cross beam 501 of the cabinet 500. The first installation area A includes a first side, a second side, a third side, and a fourth side. The first side and the third side are oppositely disposed, and the second side and the fourth side are oppositely disposed. The first side lies within the plane where the first hinge plate 411 is located, and the second side lies within the plane of the side surface of the cabinet 500. In the height direction of the cabinet 500, a first distance is left between the third side and the first side; in the width direction of the cabinet 500, a second distance is left between the fourth side and the second side.

[0090] 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.

[0091] Furthermore, in one embodiment, as Figure 7 shown, the second hinge 420 includes a second hinge plate 421, a second hinge shaft 422, and a third hinge shaft 423. The second hinge plate 421 includes a mounting plate 4211 and a connecting plate 4212. The mounting plate 4211 is mounted on the front surface (middle cross beam 502) of the cabinet 500, and the connecting plate 4212 is connected to the side of the mounting plate 4211 facing away from the front surface of the cabinet 500. The connecting plate 4212 is disposed at an angle with respect to the mounting plate 4211. The connecting plate 4212 has opposite first and second sides. The second hinge shaft 422 is disposed on the first side, and the bottom of the first cabinet door 110 is hinged to the second hinge shaft 422. The third hinge shaft 423 is disposed on the second side, and the top of the second cabinet door 120 is hinged to the third hinge shaft 423.

[0092] Exemplarily, the second hinge plate 421 can be made of a metallic material or a non-metallic material with a certain structural strength. The second hinge plate 421 includes a mutually connected mounting plate 4211 and a connecting plate 4212. The connecting plate 4212 is substantially perpendicular to the mounting plate 4211, and a plurality of mounting holes are provided on the mounting plate 4211. During actual production and manufacturing, the mounting plate 4211 and the connecting plate 4212 can be integrally formed on the same sheet of material, and then, the connecting plate 4212 can be bent relative to the mounting plate 4211 by means of stamping and folding.

[0093] The two sides in the thickness direction of the connecting plate 4212 are respectively the first side and the second side. The second hinge shaft 422 is fixedly connected to the first side, and the third hinge shaft 423 is fixedly connected to the second side.

[0094] During actual production and manufacturing, the second hinge shaft 422 and the third hinge shaft 423 can be fixedly connected to the connecting plate 4212 by welding respectively. Alternatively, the second hinge shaft 422 and the third hinge shaft 423 can be constructed as an integral piece in the shape of a long bar. The connecting plate 4212 is provided with through holes penetrating along its thickness direction. The integral piece is inserted into the through holes, and the integral piece is fixed in the through holes by welding or threaded connection. The two ends of the integral piece in the length direction on the connecting plate 4212 are respectively formed as the second hinge shaft 422 and the third hinge shaft 423.

[0095] During actual installation, according to the installation position of the box door 100, a plurality of threaded holes can be set in advance on the front surface of the box body 500. For example, as Figure 2 shown, a plurality of 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 4211 of the first hinge plate 411 are aligned with the positions of the threaded holes, and then the mounting plate 4211 is fixed to the front surface of the box body 500 by means of bolts. At this time, the connecting plate 4212 extends towards the box door 100. At the same time, the second hinge shaft 422 extends upwards along the height direction of the box body 500, and the third hinge shaft 423 extends downwards along the height direction of the box body 500.

[0096] 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 second hinge shaft 422, and a hinge hole can be set in advance at the top of the second box door 120 corresponding to the third hinge shaft 423. Then, the second hinge shaft 422 and the third hinge shaft 423 can be respectively inserted into the hinge holes of their corresponding box doors 100, and thus, the installation of the box door 100 can be realized.

[0097] In this way, the two traction components 310 on the middle cross beam 502 of the box body 500 are arranged close to the mounting plate 4211.

[0098] In addition, as Figure 4 shown, the second installation area is located on the middle cross beam 502 of the box body 500. The second installation area includes a first sub - area B1 above the mounting plate 4211 and a second sub - area B2 below the mounting plate 4211. The traction component 310 corresponding to the first box door 110 is arranged in the first sub - area B1, and the traction component 310 corresponding to the second box door 120 is arranged in the second sub - area B2;

[0099] Among them, the first sub-region B1 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 side of the mounting plate 4211. The second side is located in the plane where the side of the box body 500 is located. 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.

[0100] The second sub-region B2 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 side of the mounting plate 4211. The second side is located in the plane where the side of the box body 500 is located. 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.

[0101] In an alternative embodiment, the third distance is greater than zero and less than or equal to 60 mm, and the fourth distance is greater than zero and less than or equal to 100 mm. For example, the fourth distance is 10 mm, 20 mm, 50 mm, 70 mm, 100 mm, and the third distance is 10 mm, 20 mm, 50 mm, 60 mm.

[0102] 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.

[0103] Furthermore, in one embodiment, as Figure 8 shown, 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 mounted on the front surface (lower cross beam 503) of the box body 500. The extension plate 4312 is connected to the 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 disposed 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.

[0104] Similarly, the third hinge plate 431 and the fourth hinge shaft 432 can also be made of metal or non-metal materials 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, and the two can be integrally formed by stamping or other methods. The support plate 4311 is provided with a plurality of mounting holes, and the fourth hinge shaft 432 is fixedly arranged on the extension plate 4312 by welding or threaded connection or other methods.

[0105] 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 in the thickness direction of the support plate 4311 fit to the front surface of the box body 500. After that, make the mounting holes on the support plate 4311 correspond to the positions of the threaded holes, and then fix the support plate 4311 to the front surface of the box body 500 with 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 box door 100 is located. Moreover, the fourth hinge shaft 432 extends upward along the height direction of the box body 500.

[0106] Based on this, when installing the box door 100, an articulation hole can be set in advance at the bottom of the box door 100 corresponding to the fourth hinge 400. Then, insert the fourth hinge shaft 432 into the articulation hole. Thus, the installation of the box door 100 can be achieved.

[0107] In this way, the traction assembly 310 on the lower cross beam 503 of the box body 500 is arranged close to the third hinge plate 431. In addition, the traction assembly 310 is arranged in the third installation area C, and the third installation area C is located on the lower cross beam 503 of the box body 500, as Figure 5 shown. The third installation area C is located above the support plate 4311. The third installation area C 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 support plate 4311, and 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 seventh distance between the third side and the first side; in the width direction of the box body 500, there is an eighth distance between the fourth side and the second side.

[0108] In an alternative embodiment, the seventh distance is greater than zero and less than or equal to 60 mm, and the eighth distance is greater than zero and less than or equal to 100 mm. For example, the eighth distance is 10 mm, 20 mm, 50 mm, 70 mm, 100 mm, and the seventh distance is 10 mm, 20 mm, 50 mm, 60 mm.

[0109] 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 first sub-area B1, the second sub-area B2, the second installation area), for example, the second rotating shaft fixing seat 313 is installed in the installation area by screws.

[0110] 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, thereby realizing the rotational connection of the cabinet door 100 relative to the cabinet 500.

[0111] 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 of the cabinet 500 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.

[0112] 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.

[0113] 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 9 and Figure 10 shown, the sliding door assembly 320 includes: a base 321, a first slider 322, a second slider 323, and a connecting member 324.

[0114] Specifically, a first guide rail is formed on one side of the base 321, and a second guide rail is formed on the other side; the first slider 322 is slidably arranged on the first guide rail, and the first rotating shaft fixing seat 312 is connected to the first slider 322; the second slider 323 is slidably arranged on the second guide rail and is connected to the cabinet door 200; both ends of the connecting member 324 are respectively connected to the first slider 322 and the second slider 323.

[0115] During the opening or closing process of the box door 100, the towing 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.

[0116] Exemplarily, the base 321 has a first guide rail and a second guide rail arranged side by side and spaced apart. The first slider 322 is arranged 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 arranged 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.

[0117] As a specific implementation manner, as Figure 9 and Figure 10 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, 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 arranged in the first guide rail, and the second slider 323 is slidably arranged 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.

[0118] Considering the requirements in practical applications, limit structures can also be arranged at the ends on both sides of the first guide rail and the second guide rail. Through the limitation of the limit structures, the first slider 322 and the second slider 323 can move within a set moving range, so as to set the moving distance according to requirements to meet the usage requirements in different occasions.

[0119] Correspondingly, the towing rod 311 is configured as a long straight rod. One end of the towing 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.

[0120] As an implementation manner, asFigure 10 As shown, the first rotating shaft fixing seat 312 includes a first vertical plate and a first horizontal plate. The first vertical plate and the first horizontal plate are connected to each other and form an L-shaped structure. The first horizontal plate is provided with a shaft hole, and a first rotating shaft is inserted into the shaft hole. One end of the traction rod 311 is rotatably connected to the first rotating shaft, so as to be fixedly connected to the first rotating shaft fixing seat 312. The first vertical plate can be fixedly connected to the first slider 322 by means such as welding.

[0121] Similarly, as Figure 9 and Figure 10 shown, the second rotating shaft fixing seat 313 includes a second vertical plate and a second horizontal plate. The second vertical plate and the second horizontal plate are connected to each other and form an L-shaped structure. The second horizontal plate is provided with a shaft hole, and a second rotating shaft can be inserted into the shaft hole. The other end of the traction rod 311 is rotatably connected to the second rotating shaft, so as to be rotatably connected to the second rotating shaft fixing seat 313.

[0122] 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.

[0123] During actual installation, after the hinge plate is fixedly installed on the box body 500, the second rotating shaft fixing seat 313 can be fixed on the top wall of the box body 500 by means of structures such as bolts.

[0124] Then, the base 321 can be fixed on 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, so as to fix the base 321 on the door 100.

[0125] 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.

[0126] During actual use, asFigure 9 and Figure 10 As shown, when the door 100 of the box moves from the position closing the storage space towards the position opening the storage space relative to the box body 500, 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. 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.

[0127] Correspondingly, when the door 100 of the box moves from the position opening the storage space towards the position 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. 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.

[0128] Wherein, the first guide rail and the second guide rail are used as a kind of track, and the first slider 322 and the second slider 323 are sliding members adapted to the corresponding guide rails and can slide along the corresponding guide rails; in addition, the sliding fit between the first slider 322 and the first guide rail should at least include the case where there are balls arranged between the first slider 322 and the first guide rail, and the sliding fit between the second slider 323 and the second guide rail should at least include the case where there are balls arranged between the second slider 323 and the second guide rail.

[0129] In another alternative embodiment, as Figure 11 and Figure 12 shown, the embodiment of the present utility model provides a sliding door mechanism 300, including: a traction assembly 310 and a sliding door assembly 320.

[0130] The first end of the traction assembly 310 is configured to be rotatably arranged on the front surface of the box body 500, and the second end of the traction assembly 310 is configured to be rotatably arranged on the door 100, wherein the first end of the traction assembly 310 is arranged offset from the hinge shaft between the box body 500 and the door 100.

[0131] The sliding door assembly 320 is configured to be arranged between the second end of the traction assembly 310 and the cabinet door 200;

[0132] During the process of the cabinet door 100 opening or closing the cabinet body 500, the second end of the traction component 310 rotates relative to the cabinet door 100, thereby driving the sliding door component 320 to drive the cabinet door 200 to move along the width direction of the cabinet door 100.

[0133] In this embodiment, the first end of the traction component 310 is rotatably arranged on the front surface of the cabinet body 500. When the cabinet door 100 rotates relative to the cabinet body 500 around the hinge axis, the second end of the traction component 310 rotates in a circular motion with the hinge axis as the center. Since the first end of the traction component 310 is arranged offset from the hinge axis, the distance between the first end and the second end of the traction component 310 will change. And the position of the second end of the traction component 310 on the cabinet door 100 is fixedly set, thereby driving the second end of the traction component 310 to rotate relative to the cabinet door 100.

[0134] Optionally, the traction component 310 can be a crank mechanism or a gear component.

[0135] The sliding door component 320 is used to convert the rotational motion of the traction component 310 into a linear motion and drive the linear movement of the cabinet door 200 relative to the cabinet door 100.

[0136] Optionally, the sliding door component 320 can be a crank-slider mechanism or a lead screw mechanism.

[0137] In practical applications, during the process of opening the cabinet door 100, the cabinet door 100 drives the second end of the traction component 310 to rotate relative to the hinge axis. Based on the offset arrangement of the first end of the traction component 310 and the hinge axis, the distance between the first end and the second end of the traction component 310 increases, driving the second end of the traction component 310 to rotate clockwise relative to the cabinet door 100, thereby controlling the sliding door component 320 to drive the cabinet door 200 to move along 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 200 of the side cabinets; during the process of closing the cabinet door 100, the cabinet door 100 drives the second end of the traction component 310 to rotate relative to the hinge axis. Based on the offset arrangement of the first end of the traction component 310 and the hinge axis, the distance between the first end and the second end of the traction component 310 decreases, driving the second end of the traction component 310 to rotate counterclockwise relative to the cabinet door 100, thereby controlling the sliding door component 320 to drive the cabinet door 200 to move along 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 200 of the side cabinets when closing the cabinet door 100 and reset the cabinet door 200.

[0138] For the sliding door mechanism 300 shown in this embodiment, by rotatably arranging the first end of the traction assembly 310 on the cabinet 500, rotatably arranging the second end of the traction assembly 310 on the cabinet door 100, and arranging the first end of the traction assembly 310 offset from the hinge axis between the cabinet 500 and the cabinet door 100, and arranging a sliding door assembly 320 between the second end of the traction assembly 310 and the cabinet door 200. When the cabinet door 100 is opened, the cabinet door 100 drives the second end of the traction assembly 310 to rotate relative to the cabinet door 100, controlling the sliding door assembly 320 to drive the cabinet door 200 to move in the width direction of the cabinet door 100 away from the hinge 400, so that the cabinet door 200 does not interfere with the side cabinet body. When the cabinet door 100 is closed, it drives the second end of the traction assembly 310 to rotate relative to the cabinet door 100, controlling the sliding door assembly 320 to drive the cabinet door 200 to move in the width direction of the cabinet door 100 towards the hinge 400, so that the cabinet door 200 returns to its original position, ensuring that the cabinet door 200 does not interfere with the cabinet door 200 of the side cabinet body.

[0139] In some embodiments, as Figure 11 shown, the traction assembly 310 includes: a first link 314 and a second link 315.

[0140] The first end of the first link 314 is rotatably arranged on the front of the cabinet 500 and is offset from the hinge axis.

[0141] Wherein, the first end of the first link 314 is rotatably arranged within the installation area (the first installation area A, the first sub-area B1, the second sub-area B2, the second installation area). For example, the first end of the first link 314 is installed in the installation area through a rotating shaft fixing seat.

[0142] The first end of the second link 315 is rotatably connected to the second end of the first link 314; the second end of the second link 315 is rotatably arranged on the cabinet door 100 and is connected to the sliding door assembly 320.

[0143] It can be understood that the first link 314 and the second link 315 are connected by the hinge 400, the first link 314 and the second link 315 can rotate relative to each other, the first link 314 can rotate relative to the cabinet 500, and the second link 315 can rotate relative to the cabinet door 100.

[0144] When the second end of the second link 315 makes a circular motion around the hinge axis with the cabinet door 100, since the first end of the first link 314 is offset from the hinge axis, the distance between the second end of the second link 315 and the first end of the first link 314 changes, while the position of the second end of the second link 315 relative to the cabinet door 100 remains unchanged, thereby causing the second end of the second link 315 to rotate around the cabinet door 100 and driving the sliding door assembly 320 to drive the cabinet door 200 to move in the width direction of the cabinet door 100.

[0145] In practical applications, during the opening process of the box door 100, the box door 100 drives the second end of the second link 315 to rotate relative to the hinge axis. Based on the misaligned arrangement of the first end of the first link 314 and the hinge axis, the distance between the first end of the first link 314 and the second end of the second link 315 increases, driving the second end of the second link 315 to rotate clockwise relative to the box door 100. Furthermore, the sliding door assembly 320 is controlled to drive the cabinet door 200 to move away from the hinge 400 in the width direction of the box door 100, that is, to move to the left relative to the box door 100, so as to avoid interference between the cabinet door 200 and the cabinet doors 200 on the side cabinets; during the closing process of the box door 100, the box door 100 drives the second end of the second link 315 to rotate relative to the hinge axis. Based on the misaligned arrangement of the first end of the first link 314 and the hinge axis, the distance between the first end of the first link 314 and the second end of the second link 315 decreases, driving the second end of the second link 315 to rotate counterclockwise relative to the box door 100. Furthermore, the sliding door assembly 320 is controlled to drive the cabinet door 200 to move towards the hinge 400 in the width direction of the box door 100, that is, to move to the right relative to the box door 100, so as to ensure that the cabinet door 200 can avoid the cabinet doors 200 on the side cabinets when the box door 100 is closed and reset the cabinet door 200.

[0146] In this embodiment, by providing the first link 314 and the second link 315 in the traction assembly 310, a compact design in a smaller space can be achieved, and the structure is simple and easy to repair.

[0147] In some embodiments, as Figure 12 shown, the sliding door assembly 320 includes: a gear 326 and a rack 327.

[0148] The gear 326 is connected to the traction assembly 310 and can rotate under the drive of the traction assembly 310.

[0149] The rack 327 is meshed with the gear 326, the rack 327 extends in the width direction, and is configured to be connected to the cabinet door 200.

[0150] Among them, the traction assembly includes: a first link and a second link. The first end of the first link is rotatably provided on the side surface 501 of the box body 500.

[0151] Among them, the first end of the first link is rotatably provided in the installation area. For example, the first end of the first link is installed in the installation area through a rotating shaft fixing seat. The first end of the second link is rotatably connected to the second end of the first link; the second end of the second link is rotatably provided on the box door 100 and is meshed and connected to the gear 326 through the teeth provided at the second end of the second link, and the gear 326 is rotatably provided on the box door 100.

[0152] In an alternative embodiment, a gear 326 is provided at the second end of the traction assembly 310, and the gear 326 is meshed with a rack 327. Exemplarily, the gear 326 is provided at the second end of the second link 315.

[0153] When the cabinet door 100 is opened, the cabinet door 100 drives the second end of the traction assembly 310 to rotate relative to the hinge axis. The distance between the first end and the second end of the traction assembly 310 increases, driving the second end of the traction assembly 310 to rotate clockwise relative to the cabinet door 100. Based on the unchanged installation position of the gear 326 on the cabinet door 100, the gear 326 is driven to rotate clockwise. The rotation of the gear 326 drives the rack 327 to move away from the hinge 400 along the width direction of the cabinet door 100, and the rack 327 drives the cabinet door 100 to move away from the hinge 400, thus avoiding interference between the cabinet door 200 and the cabinet door 200 of the side cabinet. During the closing process of the cabinet door 100, the cabinet door 100 drives the second end of the traction assembly 310 to rotate relative to the hinge axis. The distance between the first end and the second end of the traction assembly 310 decreases, driving the second end of the traction assembly 310 to rotate counterclockwise relative to the cabinet door 100. Based on the unchanged installation position of the gear 326 on the cabinet door 100, the gear 326 is driven to rotate counterclockwise. The rotation of the gear 326 drives the rack 327 to move towards the hinge 400 along the width direction of the cabinet door 100, and the rack 327 drives the cabinet door 100 to move towards the hinge 400, thus ensuring that the cabinet door 200 can avoid the cabinet door 200 of the side cabinet when the cabinet door 100 is closed and resetting the cabinet door 200.

[0154] In this embodiment, by setting the sliding door assembly 320 as a gear 326 and a rack 327, the structure is simple, easy to install and maintain, and can improve the transmission efficiency.

[0155] In some embodiments, as Figure 12 shown, the sliding door mechanism 300 further includes: a track assembly 600.

[0156] The track assembly 600 is configured to be disposed between the cabinet door 100 and the cabinet door 200, and the track assembly 600 is used to guide the cabinet door 200 to move relative to the cabinet door 100 along the width direction.

[0157] It can be understood that due to the self-weight of the cabinet door 200, the cabinet door 200 may vibrate or tilt during the movement relative to the cabinet door 100. The track assembly 600 can provide a stable support and guiding function to guide the reliable and stable movement of the cabinet door 200 relative to the cabinet door 100.

[0158] In some embodiments, as Figure 12 shown, the track assembly 600 includes: a slide rail 601 and a moving member.

[0159] The slide rail 601 is disposed on the door 100 and extends in the width direction.

[0160] The moving member is movably disposed on the slide rail 601 along the width direction, and the moving member is configured to be detachably connected to the cabinet door 200 .

[0161] It can be understood that the moving part can move along the extension direction of the slide rail 601. Based on the guiding and supporting function of the slide rail 601, the moving part can move stably and reliably along the slide rail 601. Moreover, based on the higher rigidity of the slide rail 601, a higher straightness can be provided for the moving part, so that the cabinet door 200 can move stably and reliably along the width direction of the box door 100.

[0162] At the same time, the detachable connection between the moving part and the cabinet door 200 facilitates the installation of the cabinet door 200. The detachable connection improves the versatility and adaptability of the sliding door mechanism 300, simplifies the manufacturing and assembly process, and reduces the production cost.

[0163] Optionally, the detachable connection between the moving part and the cabinet door 200 can be achieved through a fastener, a snap-on connection, or a magnetic connection.

[0164] In some embodiments, Figure 12 As shown, the moving part includes a sliding part 602 and a hanging part; the sliding part 602 is movably arranged on the slide rail 601 along the width direction, and the hanging part is configured to be connected to the cabinet door 200 and hung on the sliding part 602.

[0165] It is understandable that the hanging member is used to connect the sliding member 602 and the cabinet door 200 to achieve the movement of the cabinet door 200 relative to the box door 100 driven by the sliding member 602, and the hanging member is configured to be detachably connected to the cabinet door 200.

[0166] Furthermore, the sliding member 602 of the present embodiment comprises a sliding body 6021 and an adapter seat 6022, the sliding body 6021 and the adapter seat 6022 are fixedly connected, a support frame 6011 is provided on the slide rail 601, a round hole is provided on the support frame 6011, a ball is installed in the round hole, the sliding body 6021 is in rolling contact with the slide rail 601 to move on the slide rail 601 along the width direction, and a card slot 60221 is provided on the adapter seat 6022, and the card slot 60221 is used to hang the hanging member on the sliding body 6021. The relative movement between the sliding body 6021 and the slide rail 601 of the present embodiment is rolling friction, so as to reduce friction and improve the moving efficiency of the moving member. This design can accurately control the movement trajectory and distance of the cabinet door 200, avoid interference with the cabinet side wall, and realize smooth opening and closing of the cabinet door 100.

[0167] Alternatively, ifFigure 11 As shown, the track assembly 600 is connected to the sliding door assembly 320. In this embodiment, a rack 327 is fixedly connected to the sliding body 6021. The rack 327 is meshed with a gear 326, and the second connecting rod 315 is connected to the gear 326 so that the second connecting rod 315 can control the sliding door assembly 320 to drive the movement of the sliding body 6021.

[0168] In some embodiments, the hanging member includes a fixed seat and a hanging part; the fixed seat is configured to be connected to the cabinet door 200, and the hanging part is adjustably arranged on the fixed seat in the vertical or horizontal direction, and the hanging part is hung on the sliding part 602.

[0169] It can be understood that a slight adjustment in the vertical or horizontal direction can be achieved between the hanging part and the fixed seat, so that the position deviation between the cabinet door 200 and the box door 100 can be adjusted by adjusting the relative position between the hanging part and the fixed seat, enabling the box door 100 and the cabinet door 200 to correct slight deviations in installation or manufacturing through fine-tuning, ensuring the aesthetic appearance of the installation of the box door 100 and the cabinet door 200.

[0170] Specifically, the fixed seat is connected to the cabinet door 200 to provide additional structural support for the cabinet door 200. An installation groove is formed on the fixed seat for accommodating the hanging part; the hanging part is slidably arranged in the installation groove, and a clamping joint is formed on the hanging part to adjust the relative position between the cabinet door 200 and the box door 100 by adjusting the position of the hanging part in the installation groove. Through the adjustable design, the user can adjust the position of the cabinet door 200 according to actual needs to meet the requirements of different usage scenarios.

[0171] Specifically, the clamping joint is a U-shaped downward hook that can pass through the notch and slide into the card slot 60221. The hanging part is provided with a first rectangular hole extending in the up-down direction, the fixed seat is provided with two installation holes and an installation groove extending left and right between the two installation holes, and the side wall of the installation groove is provided with a second rectangular hole extending in the left-right direction. The hanging part can slide in the installation groove. By controlling the position of the hanging part in the installation groove, the hanging part can move up and down relative to the fixed seat. Screws can be set to pass through the first rectangular hole on the installation groove and the second rectangular hole on the hanging part, and a hanging part that can be adjusted in both the up-down and left-right directions can be formed. And through the relative position between the installation holes of the fixed seat and the cabinet door 200, the position of the fixed seat and the cabinet door 200 can be adjusted in the up-down, left-right directions.

[0172] The process of installing the hanging member on the cabinet door 200 is as follows:

[0173] Thread the hanging part through the installation groove of the fixing base. Use screws to pass through the second rectangular hole, the first rectangular hole and the cabinet door 200 to integrally connect the fixing base to the cabinet door 200. Hang the card joint on the hanging part that has been connected in the card slot 60221 to complete the connection between the hanging part and the adapter base 6022. Then, by observing the positional relationship between the cabinet door 200 and the box door 100, detect whether there is a deviation. If there is a deviation, the position can be adjusted through the first rectangular hole and the second rectangular hole. When the deviation is large, the screw can be removed to separate the hanging part from the cabinet door 200 and adjust the position of the hanging part. Adjust the position of the hanging part with the cabinet door 200, the fixing base and the hanging part assembly. If the positional relationship meets the requirements and no adjustment is needed, use screws to pass through the installation holes on both sides of the fixing base and the cabinet door 200 to further fix the cabinet door 200 to the fixing base to keep its position stable. Through the above method, not only can the position of the fixing base be finely adjusted, but also it can be ensured that all fixings are firm, guaranteeing the accurate positional relationship between the cabinet door 200 and the box door 100.

[0174] 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.

[0175] 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, and at least manufacturing and installation errors should be considered. For example, errors of plus or minus 10° should be within the scope protected by the embodiments of the present invention. In addition, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
