[0058] As Figure 2 shown, the door body device of the embodiment of the present utility model includes a plurality of door body components 10, and the plurality of door body components 10 are arranged in parallel along the height direction of the box body 500. Each door body component 10 includes: a box door 100, a cabinet door 200, and at least one sliding door mechanism 300.

[0059] Among them, the box door 100 can be rotatably connected to the box body 500 through a hinge 400 and is adapted to open or close the storage space of the box body 500; the cabinet door 200 is slidably arranged on the outer side of the box door 100; the sliding door mechanism 300 includes a connected traction component 310 and a sliding door component 320. The traction component 310 is arranged on the front surface of the box body 500, and the sliding door component 320 is arranged on the box door 100 and is connected to the cabinet door 200. The traction component 310 is configured to drive the sliding door component 320 to act during the opening or closing process of the box door 100, and then drive the cabinet door 200 to move relative to the width direction of the box door 100.

[0060] Among them, the thickness of the box door 100 is 18 - 60 mm.

[0061] In practical applications, in the case where there are multiple door body components 10, the two traction components 310 corresponding to one door body component 10 are respectively arranged on the upper cross beam 501 and the middle cross beam 502 of the box body 500, and the traction component 310 corresponding to another door body component 10 is arranged on the lower cross beam 503 of the box body 500. That is to say, each door body component 10 is correspondingly provided with at least one sliding door mechanism 300, and the two traction components 310 corresponding to one door body component 10 are respectively located at different positions on the front surface of the box body 500.

[0062] It can be understood that the door 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 500, and the cabinet 500 forms a storage space, in which items such as vegetables and fruits that need to be refrigerated or frozen can be placed. Optionally, a refrigeration device and the like are also provided in the cabinet 500 of the refrigeration equipment, and the refrigeration device can perform refrigeration treatment on the storage space.

[0063] In this embodiment, the door 100 of the door device is rotatably arranged on the cabinet 500 of the refrigeration equipment through a hinge 400. The door 100 can be used to open or close the storage space in the cabinet 500. When the door 100 is in the closed position closing the storage space, the storage space is in a closed state, and the items in the storage space can be refrigerated. When the door 100 is in the open position opening the storage space, the storage space is in an open state, and the user can take out the items in the storage space.

[0064] For the convenience of describing the positional relationship between various components, in this embodiment, as Figure 2 shown, the cabinet 500 is generally constructed as a cuboid structure with a certain height. The cabinet 500 can be placed on a horizontal plane. The cabinet 500 has a height direction, a width direction, and a thickness direction that are perpendicular to each other. Among them, the height direction of the cabinet 500 is parallel to the vertical direction, and the width direction and the thickness direction are located in the horizontal plane and are perpendicular to each other.

[0065] A storage space is provided inside the cabinet 500. An opening is provided on the side of the cabinet 500 in the thickness direction, and the opening communicates with the storage space. The door 100 is connected to the side of the cabinet 500 in the thickness direction where the opening is provided. The door 100 extends along the width direction of the cabinet 500. One side of the door 100 in the width direction of the cabinet 500 is connected with a hinge 400. The door 100 can be rotatably connected to the cabinet 500 via the hinge 400, so as to ensure that the door 100 can open or close the storage space of the cabinet 500. Moreover, the side of the cabinet 500 where the door 100 is installed is the front, that is, the door 100 is installed on the front of the cabinet 500.

[0066] The door 100 is generally constructed as a flat plate-like structure with a certain thickness. The door 100 has a height direction, a width direction, and a thickness direction that are perpendicular to each other. Among them, the height direction of the door 100 is parallel to the vertical direction, and the width direction and the length direction are located in the horizontal plane and are perpendicular to each other. One side of the door 100 in the width direction can be rotatably connected to the cabinet 500 via the hinge 400. For example, as Figure 2 shown, the door 100 is connected with a hinge 400 on the right side of the cabinet 500 in the width direction, and the door 100 can be rotatably connected to the cabinet 500 via the hinge 400.

[0067] Moreover, when the cabinet door 100 is in the position of closing the storage space of the cabinet body 500, the width direction of the cabinet door 100 is parallel to the width direction of the cabinet body 500, and the thickness direction of the cabinet door 100 is parallel to the thickness direction of the cabinet body 500.

[0068] Furthermore, the cabinet door 200 can be a decorative door panel, and the cabinet door 200 is configured as a flat plate structure with a certain thickness. The cabinet door 200 is connected to the outer side of the cabinet door 100 away from the cabinet body 500. When the refrigeration device is placed together with the cabinet in an embedded manner or directly placed in the cabinet, after the cabinet door 100 is in the closed position, the cabinet door 200 can be flush with the door panel of the cabinet, that is, the outer wall surface of the cabinet door 200 away from the cabinet door 100 can be flush with the outer wall surface of the cabinet.

[0069] In the actual use scenario, the outer wall surface of the cabinet door 200 can be selected to have the same material and shape as the outer wall surface of the cabinet, and the same decoration can be attached, so that the refrigeration device can have sufficient coordination with the cabinet and ensure the aesthetics.

[0070] In one embodiment, as Figure 1 shown, the door body device and the cabinet body 500 are configured to be arranged in the installation space formed between the first cabinet body 510 and the second cabinet body 520; during the opening or closing process of the cabinet door 100, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the cabinet door 100, so that the cabinet door 200 can avoid the side walls of the first cabinet body 510 and the second cabinet body 520;

[0071] Alternatively, the door body device and the cabinet body 500 are configured to be arranged in the cabinet; during the opening or closing process of the cabinet door 100, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the cabinet door 100, so that the cabinet door 200 can avoid the side walls of the cabinet.

[0072] It can be understood that the refrigeration device includes the door body device and the cabinet body 500.

[0073] In practice, as Figure 1 shown, when the refrigeration device with the door body device and the cabinet body 500 is placed between the adjacent first cabinet body 510 and the second cabinet body 520, a cabinet door 200 can be arranged on the outer side of the cabinet door 100 in the door body device, and the cabinet door 200 can move relative to the cabinet door 100 along the width direction of the cabinet door 100. Optionally, when the cabinet 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 away from the cabinet 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 away from the cabinet door 100 are in the same direction in the thickness direction of the cabinet body 500.

[0074] At this time, during the rotation of the cabinet door 100 relative to the cabinet body 500, the sliding door mechanism 300 can drive the cabinet door 200 to move, so that the cabinet door 200 can avoid the side walls of the first cabinet body 510 and the second cabinet body 520.

[0075] Alternatively, after the refrigeration device is placed in the cabinet body, a cabinet door 200 can be arranged outside the cabinet door 100 of the door device, and the cabinet door 200 can move relative to the cabinet door 100. Optionally, when the cabinet door 100 is in a state of closing the storage space of the cabinet body 500, the outer wall surface of the cabinet door 200 facing away from the cabinet 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 cabinet door 100 are in the same direction in the thickness direction of the cabinet body 500.

[0076] At this time, during the rotation of the cabinet 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.

[0077] Thus, after the door device in this embodiment is installed on the cabinet body 500 of the refrigeration device, during the rotation of the cabinet door 100 relative to the cabinet body 500, the sliding door assembly 320 can drive the cabinet door 200 to move relative to the cabinet door 100 under the drive of the traction assembly 310. Therefore, when the refrigeration device is placed in the cabinet in an embedded manner, without affecting the coordination, aesthetics and user experience, the interference between the cabinet door 200 and the cabinet can be avoided during the opening of the cabinet door 100.

[0078] In a specific embodiment, as Figure 2 shown, the door device includes a first cabinet door 110 and a second cabinet door 120. The first cabinet door 110 and the second cabinet door 120 are arranged at intervals along the height direction of the cabinet body 500. At this time, the top of the first cabinet 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, and the bottom of the first cabinet door 110 is rotatably connected to the cabinet body 500 through a second hinge 420 provided on the middle cross beam 502. The bottom of the second cabinet 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.

[0079] 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 cabinet door 110 to move in the width direction of the first cabinet door 110. As Figure 4As shown, the traction assembly 310 located on the middle crossbeam 502 of the cabinet 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 first cabinet door 110 to move relative to the width direction of the first cabinet door 110. Thus, it can be seen that two sliding door mechanisms 300 are provided on the first cabinet door 110.

[0080] As Figure 5 shown, the traction assembly 310 located on the lower crossbeam 503 of the cabinet 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 cabinet door 120 to move relative to the width direction of the second cabinet door 120. Thus, it can be seen that one sliding door mechanism 300 is provided on the second cabinet door 120.

[0081] 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 cabinet 500 and the remaining part protrudes from the top wall towards the first cabinet door 110. The first hinge shaft 412 extends downward from the part of the first hinge plate 411 protruding from the top wall, and the top of the first cabinet door 110 is hinged to the first hinge shaft 412.

[0082] 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 part and a first protruding part that are connected to each other. The first fitting part is provided with a plurality of mounting holes, and the first hinge shaft 412 is fixedly disposed on the first protruding part by means of welding or threaded connection.

[0083] During actual installation, a plurality of threaded holes can be provided in advance on the top wall of the cabinet 500. Then, the first fitting part of the first hinge plate 411 is fitted to the top wall of the cabinet 500, and at the same time, the mounting holes on the first fitting part are aligned with the threaded holes. Then, the first fitting part is fixed to the top wall of the cabinet 500 by means of bolts. At this time, the first fitting part can cover and fit to the top wall of the cabinet 500, the first protruding part can protrude from the top wall towards the cabinet door 100, and moreover, the first hinge shaft 412 can extend downward along the height direction of the cabinet 500.

[0084] Based on this, when installing the cabinet door 100, an articulated hole can be provided in advance at the top of the cabinet door 100 corresponding to the first hinge 410. Then, the first hinge shaft 412 is inserted into the articulated hole, and thus, the installation of the cabinet door 100 can be realized.

[0085] In this way, the traction assembly 310 located on the upper crossbeam 501 of the cabinet 500 is disposed close to the first hinge plate 411.

[0086] As shown Figure 3 in the figure, the traction assembly 310 corresponding to the first box door 110 is arranged in the first installation area A, and the first installation area A is located on the upper cross beam 501 of the box body 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 arranged oppositely, the second side and the fourth side are arranged oppositely, the first side is located in the plane where the first hinge plate 411 is located, the second side is located in the plane where the side surface of the box body 500 is located. In the height direction of the box body 500, a first distance is left between the third side and the first side; in the width direction of the box body 500, a second distance is left between the fourth side and the second side.

[0087] 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.

[0088] Further, in one embodiment, as shown Figure 7 in the figure, 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 box body 500. The connecting plate 4212 is connected to the side of the mounting plate 4211 facing away from the front surface of the box body 500. The connecting plate 4212 is arranged at an angle with the mounting plate 4211. The connecting plate 4212 has a first side and a second side opposite to each other. The second hinge shaft 422 is arranged on the first side, and the bottom of the first box door 110 is hinged to the second hinge shaft 422. The third hinge shaft 423 is arranged on the second side, and the top of the second box door 120 is hinged to the third hinge shaft 423.

[0089] Exemplarily, the second hinge plate 421 can be made of a metal material or a non-metal material with a certain structural strength. The second hinge plate 421 includes a mounting plate 4211 and a connecting plate 4212 connected to each other. The connecting plate 4212 is substantially perpendicular to the mounting plate 4211. 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.

[0090] The two sides in the thickness direction of the connecting plate 4212 are the first side and the second side respectively. 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.

[0091] 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 part in the shape of a long bar. The connecting plate 4212 is provided with through holes penetrating along its thickness direction. This integral part is inserted into the through holes, and the integral part is fixed in the through holes by welding or threaded connection. The two ends of the integral part in the length direction on the connecting plate 4212 are respectively formed as the second hinge shaft 422 and the third hinge shaft 423.

[0092] During actual installation, multiple threaded holes can be set in advance on the front surface of the box body 500 according to the installation position of the box door 100. For example, as Figure 2 shown, multiple threaded holes are set at the position corresponding to the gap between the first box door 110 and the second box door 120 on the front surface of the box body 500. Then, the mounting holes on the mounting plate 4211 of the first hinge plate 411 are made to correspond to the positions of the threaded holes, and then the mounting plate 4211 is fixed to the front surface of the box body 500 with the help of bolts. At this time, the connecting plate 4212 extends towards the direction of the box door 100. Meanwhile, 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.

[0093] 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 achieved.

[0094] In this way, the traction assembly 310 on the middle cross beam 502 of the box body 500 is arranged close to the mounting plate 4211.

[0095] In addition, as Figure 4 shown, the second installation area B is located on the middle cross beam 502 of the box body 500. The second installation area B is located above the mounting plate 4211, and the traction assembly 310 corresponding to the first box door 110 is arranged within the second installation area B.

[0096] Among them, the second installation area B includes a first side, a second side, a third side, and a fourth side. The first side and the third side are arranged opposite to each other, 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 surface 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.

[0097] 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.

[0098] 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 one 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.

[0099] Similarly, the third hinge plate 431 and the fourth hinge shaft 432 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 stamping or the like. The support plate 4311 is provided with a plurality of mounting holes. The fourth hinge shaft 432 is fixedly disposed on the extension plate 4312 by welding or threaded connection or the like.

[0100] During actual installation, a plurality of threaded holes can be provided 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. Then, let the mounting holes on the support plate 4311 correspond to the positions of the threaded holes. Then, fix the support plate 4311 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 toward 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.

[0101] Based on this, when installing the door 100, an articulated hole can be provided in advance at the bottom of the door 100 corresponding to the fourth hinge 400. Then, insert the fourth hinge shaft 432 into the articulated hole. Thus, the installation of the door 100 can be achieved.

[0102] 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 third installation area C is located on the lower cross beam 503 of the box body 500, and the traction assembly 310 is disposed within the third installation area C, as Figure 5As 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, and the second side and the fourth side are oppositely arranged. The first side is the top side of the support plate 4311. 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, a fifth distance is left between the third side and the first side; in the width direction of the box body 500, a sixth distance is left between the fourth side and the second side.

[0103] In an alternative embodiment, the fifth distance is greater than zero and less than or equal to 60 mm, and the sixth distance is greater than zero and less than or equal to 100 mm. For example, the sixth distance is 10 mm, 20 mm, 50 mm, 70 mm, 100 mm, and the fifth distance is 10 mm, 20 mm, 50 mm, 60 mm.

[0104] In a specific embodiment, as Figure 2 shown, the box body 500 is provided with two storage spaces at intervals along its height direction. The top of the box body 500 is provided with a first hinge 410, the lower cross beam 503 of the box body 500 is provided with a third hinge 430, and a second hinge 420 is provided at the middle of the box body 500 and approximately at a position between the two storage spaces (the middle cross beam 502). The door device includes two box doors 100, namely a first box door 110 and a second box door 120. The first box door 110 and the second box door 120 are arranged at intervals along the height direction of the box body 500, and the first box door 110 and the second box door 120 respectively correspond to the two storage spaces of the box body 500. During installation, the top of the first box door 110 is hinged to the first hinge shaft 412 of the first hinge 410, the bottom of the first box door 110 is hinged to the second hinge shaft 422 of the second hinge 420, the top of the second box door 120 is hinged to the third hinge shaft 423 of the second hinge 420, and the bottom of the second box door 120 is hinged to the fourth hinge shaft 432 of the third hinge 430.

[0105] Thus, through the above setting method, the first box door 110 and the second box door 120 can be rotatably connected to the box body 500.

[0106] In one embodiment, to ensure that the traction assembly 310 can drive the sliding door assembly 320 to move, the traction assembly 310 includes a traction rod 311, a first rotating shaft fixing seat 312, and a second rotating shaft fixing seat 313; the first rotating shaft fixing seat 312 is connected to the sliding door assembly 320, the second rotating shaft fixing seat 313 is connected to the front surface of the cabinet 500, one end of the traction rod 311 is rotatably connected to the first rotating shaft fixing seat 312, and the other end of the traction rod 311 is rotatably connected to the second rotating shaft fixing seat 313; during the opening or closing process of the cabinet door 100, the traction rod 311 drives the sliding door assembly 320 to act, thereby driving the cabinet door 200 to move relative to the width direction of the cabinet door 100. Among them, the second rotating shaft fixing seat 313 is located within the installation area (the first installation area A, the second installation area B, the third installation area C). For example, the second rotating shaft fixing seat 313 is installed in the installation area by screws.

[0107] Exemplarily, the hinge 400 may include a hinge plate and a hinge shaft, and the hinge shaft is fixedly arranged on the hinge plate by means such as welding. During actual installation, the hinge plate can be fixedly arranged on the cabinet 500 by means of structures such as bolts. Threaded holes can be provided in the cabinet door 100 in advance. After the hinge plate is fixed to the cabinet 500, the hinge shaft can be inserted into the hinge hole of the cabinet door 100, so as to realize the rotational connection of the cabinet door 100 relative to the cabinet 500.

[0108] In the traction assembly 310, the first rotating shaft fixing seat 312 is arranged on the sliding door assembly 320, the second rotating shaft fixing seat 313 is arranged on the front surface and close to the hinge plate, and both ends of the traction rod 311 are respectively rotatably connected to the first rotating shaft fixing seat 312 and the second rotating shaft fixing seat 313.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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 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.

[0115] Considering the requirements in practical applications, limit structures can also be provided at the ends on both sides of the first guide rail 3211 and the second guide rail 3212. Through the limitation of the limit structures, the first slider 322 and the second slider 323 can move within a set moving range, so as to set the moving distance according to requirements to meet the usage requirements of different occasions.

[0116] Accordingly, the drawbar 311 is configured as a long straight bar. One end of the drawbar 311 is rotatably connected to the first rotating shaft fixed seat 312 via the first rotating shaft, and the other end is rotatably connected to the second rotating shaft fixed seat 313 via the second rotating shaft.

[0117] As an implementation, as Figure 10 shown, the first rotating shaft fixed 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 fixed seat 312. The first vertical plate can be fixedly connected to the first slider 322 by means such as welding.

[0118] Similarly, as Figure 9 and Figure 10 shown, the second rotating shaft fixed 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 fixed seat 313.

[0119] 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. 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.

[0120] During actual installation, after the hinge plate is fixedly installed on the box body 500, the second rotating shaft fixed seat 313 can be fixed on the front of the box body 500 by means of structures such as bolts.

[0121] 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.

[0122] 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.

[0123] During actual use, as Figure 9 and Figure 10 shown, when the door 100 moves relative to the cabinet body 500 from the position of closing the storage space towards the position of opening the storage space, since the first rotating shaft fixing seat 312 is fixed to the door 100 following the hinge seat, during the rotation of the door 100, the first slider 322 will move along the first direction on the first guide rail 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. Among them, the first direction is opposite to the second direction, and both the first direction and the second direction are parallel to the width direction of the door 100.

[0124] Correspondingly, when the door 100 moves relative to the cabinet body 500 from the position of opening the storage space towards the position of closing the storage space, during the rotation of the door 100, the first slider 322 will move along the direction opposite to the first direction on the first guide rail 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.

[0125] In an embodiment of the present utility model, as Figure 11 and Figure 12As shown, 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. On one side of the base 321, a first guide rail 3211 is formed, and on the other side, a second guide rail 3212 is formed. The first slider 322 is 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. 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.

[0126] The base 321 can be fixed to the cabinet door 100 by means of structures such as bolts. Exemplarily, on both sides in the length direction of the base 321, a first receiving plate 326 and a second receiving plate 327 are respectively provided, and through holes are respectively provided on the first receiving plate 326 and the second receiving plate 327. During installation, an external bolt hole can pass through the through holes on the first receiving plate 326 and the second receiving plate 327 and be connected to the cabinet door 100, thereby fixing the base 321 to the cabinet door 100.

[0127] 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 provided on the front surface of the box body 500 and is arranged offset from the hinge axis.

[0128] Among them, the first end of the first connecting rod is rotatably provided 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 provided on the cabinet door 100 and is meshed and connected to the tooth portion on the first slider 322 through a gear provided at the second end of the second connecting rod.

[0129] 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.

[0130] 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 arranged 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 in the width direction of the cabinet door 100.

[0131] 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. Furthermore, it controls the second slider 323 to drive the cabinet door 200 to move away from the hinge 400 along the width direction of the cabinet door 100, that is, to move to the left relative to the cabinet door 100. In this way, interference between the cabinet door 200 and the cabinet doors 200 of the side cabinets can be avoided. 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. Furthermore, it controls the second slider 323 to drive the cabinet door 200 to move closer to the hinge 400 along the width direction of the cabinet door 100, that is, to move to the right relative to the cabinet door 100. In this way, it can be ensured that the cabinet door 200 can avoid the cabinet doors 200 of the side cabinets when the cabinet door 100 is closed, and the cabinet door 200 can be reset.

[0132] Specifically, during the process of the cabinet door 100 rotating outward and opening relative to the cabinet body 500, the cabinet door 100 drives the first slider 322 to slide towards the first hinge 410. At the same time, the first slider 322 drives the second slider 323 to slide in the opposite direction (i.e., away from the first hinge 410) through the connecting piece 324, thereby avoiding interference between the cabinet door 200 and 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 (i.e., towards the first hinge 410) through the connecting piece 324, thereby avoiding interference between the cabinet door 200 and obstacles after closing.

[0133] 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.

[0134] 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.

[0135] Among them, 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 parts that are adapted to the corresponding guide rails and can slide along the corresponding guide rails; in addition, the sliding cooperation between the first slider 322 and the first guide rail should at least include the situation that a ball is set between the first slider 322 and the first guide rail, and the sliding cooperation between the second slider 323 and the second guide rail should at least include the situation that a ball is set between the second slider 323 and the second guide rail.

[0136] 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 .

[0137] like Figure 11 and Figure 12 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 front of the box body 500. One end of the traction rod 311 is rotatably connected to the first rotating shaft fixing seat 312, and the other end of the traction rod 311 is rotatably connected to the second rotating shaft fixing seat 313.

[0138] 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.

[0139] In one embodiment of the present invention, Figure 9 and Figure 10As 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 its two ends are respectively connected to one ends of the first slider 322 and the second slider 323; the second connecting member 3242 bypasses the other end of the base 321, and its two ends are respectively connected to the other ends of the first slider 322 and the second slider 323.

[0140] In this embodiment, by connecting the first connecting member 3241 around one end of the base 321 to the first slider 322 and the second slider 323 respectively, when the first slider 322 slides away from this end of the base 321 under the drive of the cabinet door 100, the first slider 322 drives the second slider 323 to slide towards this end of the base 321 through the first connecting member 3241; meanwhile, by connecting the second connecting member 3242 around the other end of the base 321 to the first slider 322 and the second slider 323 respectively, when the first slider 322 slides away from the other end of the base 321 under the drive of the cabinet door 100, the first slider 322 drives the second slider 323 to slide towards the other end of the base 321 through the second connecting member 3242, so as to achieve that when the first slider 322 slides towards both ends of the base 321 respectively, it can drive the second slider 323 to slide in the opposite direction to the first slider 322, and further enable the cabinet door 200 to slide relative to the cabinet door 100 when the cabinet door 100 opens and closes, so as to avoid interference with obstacles and affect the opening and closing of the cabinet door 100.

[0141] As Figure 11 and Figure 12 shown, a first rolling gap D1 is formed between the first slider 322 and the first guide rail 3211, and a second rolling gap D2 is formed between the second slider 323 and the second guide rail 3212; the rolling elements 328 include a first ball 3281 and a second ball 3282, the first ball 3281 is rotatably arranged in the first rolling gap D1, and the second ball 3282 is rotatably arranged in the second rolling gap D2.

[0142] In this embodiment, by forming a first rolling gap D1 and a second rolling gap D2 between the first slider 322 and the first guide rail 3211 and between the second slider 323 and the second guide rail 3212 respectively, it can be avoided that the first slider 322 directly contacts the first guide rail 3211 and the second slider 323 directly contacts the second guide rail 3212, and rotatable first balls 3281 and second balls 3282 are respectively arranged in the first rolling gap D1 and the second rolling gap D2, so that the first slider 322 can slide along the first guide rail 3211 through the rolling of the first ball 3281, and the second slider 323 can slide along the second guide rail 3212 through the rolling of the second ball 3282, with small friction and smoother sliding.
