The following further describes the door body device and the refrigeration device in the present embodiment with reference to Figures 3 to 14 shown below.

[0055] Specifically, as Figure 3 andFigure 4 As shown in Figure 4 , the door body device in this embodiment includes a plurality of door body components 100, and the plurality of door body components 100 are arranged side by side in the height direction of the box body 500.

[0056] Among them, each door body component 100 includes a box door 110, a cabinet door 200 and a sliding door mechanism 300. The cabinet door 200 is slidably arranged outside the box door 110. The bottom of the box door 110 is rotatably connected to the box body 500 through a hinge 400. 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 hinge 400, and the sliding door component 320 is arranged between the box door 110 and 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 110, and then drive the cabinet door 200 to move in the width direction relative to the box door 110. Among them, the hinge 400 is a single-axis hinge.

[0057] Among them, the thickness of the box door 110 is 18 - 60 mm. Exemplarily, the thickness of the box door 110 is 18 mm, 25 mm, 50 mm, 60 mm, etc. The thickness of the cabinet door 200 is 12 - 26 mm. Exemplarily, the thickness of the cabinet door 200 is 12 mm, 18 mm, 24 mm, 26 mm, etc. In addition, the cabinet door 200 can be a wooden door or a plastic door, etc.

[0058] It can be understood that the door body device in this embodiment can be used in refrigeration equipment such as refrigerators, freezers, ice makers, etc. Among them, the refrigeration equipment includes a box body 500, and the box body 500 forms a storage space, and items such as vegetables and fruits that need to be refrigerated or frozen can be placed in the storage space. Optionally, a refrigeration device and the like are also arranged in the box body 500 of the refrigeration equipment, and the refrigeration device can perform refrigeration treatment on the storage space.

[0059] In this embodiment, the door body device includes a plurality of door body components 100. For example, the number of the door body components 100 can be two, three or four, and the plurality of door body components 100 are arranged at intervals in the height direction of the box body 500. Exemplarily, Figure 3 the door body device shown in Figure 3 includes two door body components 100.

[0060] Furthermore, each door body component 100 includes a box door 110, a cabinet door 200 and a sliding door mechanism 300.

[0061] Among them, the bottom of the door 110 is rotatably arranged on the cabinet 500 of the refrigeration device through a hinge 400. The door 110 can be used to open or close the storage space in the cabinet 500. When the door 110 is in the closed position for closing the storage space, the storage space is in a closed state, and the items in the storage space can be refrigerated. When the door 110 is in the open position for opening the storage space, the storage space is in an open state, and the user can take out the items in the storage space.

[0062] For the convenience of describing the positional relationship between various components, in this embodiment, as Figure 3 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.

[0063] 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 110 is connected to the side of the cabinet 500 in the thickness direction where the opening is provided. The door 110 extends along the width direction of the cabinet 500. A hinge 400 is connected to the bottom on one side of the door 110 in the width direction of the cabinet 500. The door 110 can be rotatably connected to the cabinet 500 via the hinge 400, so as to ensure that the door 110 can open or close the storage space of the cabinet 500.

[0064] Moreover, the side of the cabinet 500 where the door 110 is installed is the front, that is, the door 110 is installed on the front of the cabinet 500.

[0065] The door 110 is generally constructed as a flat plate structure with a certain thickness. The door 110 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 110 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. The bottom on one side of the door 110 in the width direction can be rotatably connected to the cabinet 500 via the hinge 400. For example, as Figure 3 shown, the hinge 400 is connected to the bottom on the right side of the door 110 in the width direction of the cabinet 500, and the door 110 can be rotatably connected to the cabinet 500 via the hinge 400.

[0066] Moreover, when the door 110 is in the position of closing the storage space of the cabinet 500, the width direction of the door 110 is parallel to the width direction of the cabinet 500, and the thickness direction of the door 110 is parallel to the thickness direction of the cabinet 500.

[0067] Furthermore, the cabinet door 200 can be a decorative door panel. 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 door 110 of the refrigerator cabinet that faces away from the cabinet body 500. When the refrigeration device is placed in the cabinet in an embedded manner or directly placed in the cabinet, after the door 110 of the refrigerator cabinet 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 that faces away from the door 110 of the refrigerator cabinet can be flush with the outer wall surface of the cabinet.

[0068] 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 to make the refrigeration device have sufficient coordination with the cabinet and ensure the aesthetics.

[0069] After the door device in this embodiment is installed on the cabinet body 500 of the refrigeration device, multiple door assemblies 100 can be arranged at intervals along the height direction of the cabinet body 500. When the door 110 in each door assembly 100 rotates to open or close the storage space of the cabinet body 500 relative to the cabinet body 500, the sliding door mechanism 300 can drive the cabinet door 200 to move relative to the door 110 of the refrigerator cabinet in the width direction of the door 110 of the refrigerator cabinet. Thus, when the refrigeration device is placed in the cabinet in an embedded manner, without affecting the coordination, aesthetics and the user experience, interference between the cabinet door 200 and the cabinet can be avoided during the process of opening the door 110 of the refrigerator cabinet.

[0070] In one embodiment, as Figure 4 shown, the door 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 door 110 of the refrigerator cabinet, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the door 110 of the refrigerator cabinet so that the cabinet door 200 avoids the side walls of the first cabinet body 510 and the second cabinet body 520;

[0071] Or, the door device and the cabinet body 500 are configured to be arranged in the cabinet; during the process of opening or closing the door 110 of the refrigerator cabinet, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the door 110 of the refrigerator cabinet so that the cabinet door 200 avoids the side walls of the cabinet.

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

[0073] In practice, as Figure 4As shown, when the refrigeration device with the door body device and the cabinet 500 is placed between the adjacent first cabinet 510 and the second cabinet 520, a plurality of door body components 100 in the door body device can be arranged at intervals along the height direction of the cabinet 500. A cabinet door 200 is arranged on the outer side of the cabinet door 110 in each door body component 100, and the cabinet door 200 can move relative to the cabinet door 110 along the width direction of the cabinet door 110. Optionally, when the cabinet door 110 is in the state of closing the storage space of the cabinet 500, the outer wall surface of the cabinet door 200 facing away from the cabinet door 110 can be flush with the outer wall surfaces of the first cabinet 510 and the second cabinet 520, and the outer wall surfaces of the first cabinet 510 and the second cabinet 520 and the outer wall surface of the cabinet door 200 facing away from the cabinet door 110 are in the same direction in the thickness direction of the cabinet 500.

[0074] At this time, during the rotation of the cabinet door 110 relative to the cabinet 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 510 and the second cabinet 520.

[0075] Alternatively, after the refrigeration device is placed in the cabinet, a cabinet door 200 can be arranged on the outer side of the cabinet door 110 of each door body component 100, and the cabinet door 200 can move relative to the cabinet door 110. Optionally, when the cabinet door 110 is in the state of closing the storage space of the cabinet 500, the outer wall surface of the cabinet door 200 facing away from the cabinet door 110 can be flush with the outer wall surface of the cabinet, and the outer wall surface of the cabinet and the outer wall surface of the cabinet door 200 facing away from the cabinet door 110 are in the same direction in the thickness direction of the cabinet 500.

[0076] At this time, during the rotation of the cabinet door 110 relative to the cabinet 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.

[0077] Further, in the sliding door mechanism 300 of the present embodiment, as Figure 10 and Figure 12 shown, the sliding door mechanism 300 includes a connected traction component 310 and a sliding door component 320. The traction component 310 can be arranged on the hinge 400, the sliding door component 320 can be arranged on the cabinet door 110, and the sliding door component 320 can also be connected to the cabinet door 200. During the rotation of the cabinet door 110 relative to the cabinet 500, the traction component 310 can drive the sliding door component 320 to act, and thereby drive the cabinet door 200 to move relative to the cabinet door 110.

[0078] Exemplarily, since the hinge 400 is fixedly connected to the cabinet 500, during the rotation of the cabinet door 110 relative to the cabinet 500, the traction component 310 can apply a pulling force to the sliding door component 320, and then the sliding door component 320 drives the cabinet door 200 to move based on this pulling force.

[0079] Thus, after the door body device in this embodiment is installed on the cabinet 500 of the refrigeration device, a plurality of door body assemblies 100 can be arranged at intervals along the height direction of the cabinet 500. Each door body assembly 100 can at least correspond to one storage space of the cabinet 500. During the rotation of the cabinet door 110 in each door body assembly 100 relative to the cabinet 500, the sliding door assembly 320 can drive the cabinet door 200 to move relative to the cabinet door 110 under the drive of the traction assembly 310. 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 opening of the cabinet door 110 while ensuring coordination, aesthetics, and not affecting the user experience.

[0080] Further, in one embodiment, as Figure 3 shown, the hinge 400 includes a first hinge 430 and a second hinge 420. Both the first hinge 430 and the second hinge 420 are arranged on the front of the cabinet 500; the door body device includes a first cabinet door 111 and a second cabinet door 112. The bottom of the first cabinet door 111 is rotatably connected to the cabinet 500 through the first hinge 430, and the bottom of the second cabinet door 112 is rotatably connected to the cabinet 500 through the second hinge 420.

[0081] Exemplarily, the number of hinges 400 is at least two. The hinge 400 at least includes a first hinge 430 and a second hinge 420. Among them, the first hinge 430 is used for fixedly arranging on the front of the cabinet 500 and is approximately located in the middle in the height direction of the cabinet 500, and the second hinge 420 is used for fixedly arranging on the front of the cabinet 500 and is approximately located at the bottom in the height direction of the cabinet 500. Both the first hinge 430 and the second hinge 420 can be used to connect the cabinet door 110.

[0082] The door body device includes two door body assemblies 100, namely a first door body assembly and a second door body assembly. The first door body assembly includes a first cabinet door 111, and the second door body assembly includes a second cabinet door 112. As Figure 3 shown, the first cabinet door 111 and the second cabinet door 112 are arranged at intervals in the height direction of the cabinet 500.

[0083] The bottom of the first cabinet door 111 can be rotatably connected to the cabinet 500 through the first hinge 430, and the bottom of the second cabinet door 112 can be rotatably connected to the cabinet 500 through the second hinge 420.

[0084] In practical applications, according to different refrigeration requirements, the cabinet 500 of different refrigeration devices is provided with different numbers of storage spaces, which are arranged at intervals along the height direction of the cabinet 500. Some of the storage spaces are for refrigeration and some are for freezing. Correspondingly, in order to be able to close these storage spaces targeted, the number of the cabinet doors 110 can be multiple, and each cabinet door 110 corresponds to at least one of the storage spaces.

[0085] For example, as Figure 3 shown, the cabinet 500 is provided with two storage spaces at intervals in the vertical direction. These two storage spaces can be used for refrigeration and freezing respectively. The number of the cabinet doors 110 is two, namely the first cabinet door 111 and the second cabinet door 112. The two cabinet doors 110 correspond to the two storage spaces one by one. At this time, the two storage spaces can be opened or closed independently through the two cabinet doors 110.

[0086] For another example, the cabinet 500 can be provided with three storage spaces at intervals in the vertical direction, namely the first space, the second space and the third space. The first space and the second space are for refrigeration, and the third space is for freezing. The number of the cabinet doors 110 is two, namely the first cabinet door 111 and the second cabinet door 112. Among them, the first cabinet door 111 corresponds to the first space and the second space one by one, and the second cabinet door 112 corresponds to the third space. At this time, the first space and the second space can be opened or closed simultaneously by using the first cabinet door 111, and the opening and closing state of the third space can be controlled independently by using the second cabinet door 112.

[0087] It can be understood that in this embodiment, each cabinet door 110 can correspond to a single storage space. At this time, the cabinet door 110 can control the opening and closing state of the storage space independently. Or, according to the requirements, each cabinet door 110 can also correspond to multiple adjacent storage spaces. At this time, the cabinet door 110 can control the opening and closing states of the multiple storage spaces simultaneously.

[0088] Furthermore, in one embodiment, as Figure 5As shown, the first hinge 430 includes a first hinge plate 431, a first hinge shaft 432, and a second hinge shaft 433. The first hinge plate 431 includes a mounting plate 4311 and a connecting plate 4312. The mounting plate 4311 is mounted on the front surface of the box body 500. The connecting plate 4312 is connected to the side of the mounting plate 4311 facing away from the front surface of the box body 500. The connecting plate 4312 is disposed at an angle to the mounting plate 4311. The connecting plate 4312 has opposite first and second sides. The first hinge shaft 432 is disposed on the first side, and the bottom of the first door 111 is hinged to the first hinge shaft 432. The second hinge shaft 433 is disposed on the second side, and the top of the second door 112 is hinged to the second hinge shaft 433. The traction assembly 310 is disposed on one of the first hinge plate 431 and the first hinge shaft 432.

[0089] Exemplarily, the first hinge plate 431, the first hinge shaft 432, and the second hinge shaft 433 can be made of a metal material or a non-metal material with a certain structural strength. The first hinge plate 431 includes a mounting plate 4311 and a connecting plate 4312 that are connected to each other. The connecting plate 4312 is substantially perpendicular to the mounting plate 4311. A plurality of mounting holes are provided on the mounting plate 4311. During actual production and manufacturing, the mounting plate 4311 and the connecting plate 4312 can be integrally formed on the same sheet of material. Thereafter, the connecting plate 4312 can be bent relative to the mounting plate 4311 by means of stamping and folding.

[0090] The two sides in the thickness direction of the connecting plate 4312 are respectively the first side and the second side. The first hinge shaft 432 is fixedly connected to the first side, and the second hinge shaft 433 is fixedly connected to the second side.

[0091] During actual production and manufacturing, the first hinge shaft 432 and the second hinge shaft 433 can be respectively fixedly connected to the connecting plate 4312 by means of welding. Alternatively, the first hinge shaft 432 and the second hinge shaft 433 can be configured as an integral piece in the shape of a long bar. The connecting plate 4312 is provided with a through hole penetrating in its thickness direction. The integral piece is inserted into the through hole, and the integral piece is fixed in the through hole by means of welding or threaded connection. The two ends of the integral piece in the length direction on the connecting plate 4312 are respectively formed as the first hinge shaft 432 and the second hinge shaft 433.

[0092] During actual installation, as Figure 8 shown, multiple threaded holes can be provided in advance on the front surface of the box body 500 according to the installation position of the door 110. For example, as Figure 3As shown, a plurality of threaded holes are provided at the position of the gap between the first door 111 and the second door 112 on the front face of the box body 500. Then, the mounting holes on the mounting plate 4311 of the first hinge plate 431 are aligned with the positions of the threaded holes, and then the mounting plate 4311 is fixed to the front face of the box body 500 by means of bolts. At this time, the connecting plate 4312 extends towards the direction of the door 110. At the same time, the first hinge shaft 432 extends upward along the height direction of the box body 500, and the second hinge shaft 433 extends downward along the height direction of the box body 500.

[0093] Based on this, when installing the door 110, hinge holes can be provided in advance at the bottom of the first door 111 and, at the same time, hinge holes can be provided in advance at the top of the second door 112. Then, the first hinge shaft 432 can be inserted into the hinge hole at the bottom of the first door 111, and the second hinge shaft 433 can be inserted into the hinge hole at the top of the second door 112. Thus, the installation of the first door 111 and the second door 112 can be achieved.

[0094] In addition, the first hinge 430 can be provided with at least one traction component 310. For example, the first door 111 is connected to a sliding door mechanism 300, and the traction component 310 in the sliding door mechanism 300 can be connected to the first hinge plate 431 or the first hinge shaft 432.

[0095] In one embodiment, as Figure 8 shown, the first door 111 is provided with a sliding door mechanism 300, and the traction component 310 in the sliding door mechanism 300 can be fixedly connected to the mounting plate 4311 via bolts.

[0096] Furthermore, in one embodiment, the central axis of the first hinge shaft 432 and the central axis of the second hinge shaft 433 are coaxially arranged.

[0097] It can be understood that by arranging the central axis of the first hinge shaft 432 and the central axis of the second hinge shaft 433 to be collinear, the first door 111 and the second door 112 can be rotated around the same rotation axis, so that the connection structure between the door 110 and the box body 500 is more reasonable and more convenient for installation.

[0098] Furthermore, in one embodiment, as Figure 6As shown, the second hinge 420 includes a second hinge plate 421 and a third hinge shaft 422. The second hinge plate 421 includes a support plate 4211 and an extension plate 4212. The support plate 4211 is installed on the front surface of the box body 500. The extension plate 4212 is connected to one side of the support plate 4211 facing away from the front surface of the box body 500. The support plate 4211 and the extension plate 4212 are arranged at an angle. The third hinge shaft 422 is arranged on the top surface of the extension plate 4212 and extends upward. The bottom of the second door 112 is hinged to the third hinge shaft 422. The traction assembly 310 is arranged on one of the second hinge plate 421 and the third hinge shaft 422.

[0099] Exemplarily, the second hinge plate 421 and the third hinge shaft 422 can also be made of a metal or non-metal material with a certain structural strength. The second hinge plate 421 includes a support plate 4211 and an extension plate 4212 that are connected to each other. The extension plate 4212 is substantially perpendicular to the support plate 4211. The two can be integrally formed by stamping or other means. The support plate 4211 is provided with a plurality of mounting holes. The third hinge shaft 422 is fixedly arranged on the extension plate 4212 by means of welding or threaded connection.

[0100] During actual installation, a plurality of threaded holes can be set in advance at a position on the front surface of the box body 500 and near the bottom. Then, one side in the thickness direction of the support plate 4211 is attached to the front surface of the box body 500, and the mounting holes on the support plate 4211 are made to correspond to the positions of the threaded holes. Then, the support plate 4211 is fixed to the front surface of the box body 500 with bolts. The extension plate 4212 is connected to the other side in the thickness direction of the support plate 4211 and extends in the direction of the second door 112. Moreover, the third hinge shaft 422 extends upward along the height direction of the box body 500.

[0101] Based on this, when installing the door 110, an articulation hole can be set in advance at the bottom of the second door 112. Then, the third hinge shaft 422 is inserted into the articulation hole. Thus, the installation of the second door 112 can be achieved.

[0102] For example, as Figure 9 shown, during actual installation, the support plate 4211 is fixed at a position on the front surface of the box body 500 and near the bottom. The second door 112 is rotatably connected to the third hinge shaft 422. Some structures in the traction assembly 310 can be connected to the support plate 4211 with bolts.

[0103] Furthermore, in one embodiment, as Figure 7As shown, the hinge 400 further includes a third hinge 410, which includes a third hinge plate 411 and a fourth hinge shaft 412. A part of the third hinge plate 411 covers the top wall of the box body 500 and the remaining part protrudes from the top wall towards the first box door 111. The fourth hinge shaft 412 extends downward from the part of the third hinge plate 411 that protrudes from the top wall, and the top of the first box door 111 is hinged to the fourth hinge shaft 412.

[0104] Exemplarily, the third hinge plate 411 and the fourth hinge shaft 412 can be made of a metal or non-metal material with a certain structural strength. The third 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 fourth hinge shaft 412 is fixedly arranged on the first protruding portion by means of welding or threaded connection.

[0105] 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 third hinge plate 411 is fitted to the top wall of the box body 500, and at the same time, the mounting holes on the first fitting portion are aligned with the threaded holes. Then, the first fitting portion is fixed to the top wall of the box body 500 by means of bolts. At this time, the first fitting portion can cover and fit to the top wall of the box body 500, the first protruding portion can protrude from the top wall towards the first box door 111, and moreover, the fourth hinge shaft 412 can extend downward along the height direction of the box body 500.

[0106] Based on this, when installing the box door 110, a hinge hole can be provided in advance at the top of the first box door 111. Then, the fourth hinge shaft 412 is inserted into the hinge hole, and thus, the installation of the first box door 111 can be achieved.

[0107] Moreover, a sliding door mechanism 300 is connected to the box door 110 corresponding to the third hinge 410. The traction assembly 310 in the sliding door mechanism 300 can be arranged on the third hinge plate 411 or on the fourth hinge shaft 412.

[0108] For example, as Figure 5 shown, in one embodiment, a vertical plate 413 is provided on the third hinge plate 411. The vertical plate 413 extends downward along the thickness direction of the third hinge plate 411. The vertical plate 413 is provided with mounting holes. During installation, a part of the structure in the traction assembly 310 can be connected to the vertical plate 413 by means of bolts.

[0109] In a specific embodiment, as Figure 3As shown, the box body 500 is provided with two storage spaces at intervals along its height direction. A first hinge 430 is provided in the middle of the box body 500 and is roughly located between the two storage spaces. A second hinge 420 is provided at the bottom of the box body 500, and a third hinge 410 is provided at the top of the box body 500. The door device includes two door components 100. The two door components 100 respectively include a first box door 111 and a second box door 112. The first box door 111 and the second box door 112 are arranged at intervals along the height direction of the box body 500, and the first box door 111 and the second box door 112 respectively correspond to the two storage spaces of the box body 500.

[0110] During installation, the top of the first box door 111 is hinged to the fourth hinge shaft 412 of the third hinge 410, and the bottom of the first box door 111 is hinged to the first hinge shaft 432 of the first hinge 430. The top of the second box door 112 is hinged to the second hinge shaft 433 of the first hinge 430, and the bottom of the second box door 112 is hinged to the third hinge shaft 422 of the second hinge 420.

[0111] Thus, through the above setting method, the first box door 111 and the second box door 112 can be rotatably connected to the box body 500.

[0112] Further, in one embodiment, as Figure 10 shown, in order to ensure that the traction assembly 310 can drive the sliding door assembly 320 to move, the hinge 400 includes a hinge plate and a hinge shaft provided on the hinge plate. The hinge plate is provided on the box body 500, and the bottom of the box door 110 is rotatably provided on the box body 500 through the hinge shaft; 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 hinge plate, 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 box door 110, the traction rod 311 drives the sliding door assembly 320 to act, and further drives the cabinet door 200 to move relative to the width direction of the box door 110.

[0113] Exemplarily, the hinge 400 may include a hinge plate and a hinge shaft. The hinge shaft is fixedly arranged on the hinge plate by means of welding or the like. During actual installation, the hinge plate can be fixedly arranged on the box body 500 by means of structures such as bolts. Threaded holes can be provided in the box door 110 in advance. After the hinge plate is fixed to the box body 500, the hinge shaft can be inserted into the hinge hole of the box door 110, so as to realize the rotational connection of the box door 110 relative to the box body 500.

[0114] 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 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.

[0115] In actual use, when the box door 110 rotates between the positions of opening or closing the storage space relative to the box body 500, the traction assembly 310 can pull the sliding door assembly 320 to act, so that the sliding door assembly 320 drives the cabinet door 200 to move in the width direction of the box door 110 relative to the box door 110.

[0116] Further, in one embodiment, in order to enable the sliding door assembly 320 to effectively drive the cabinet door 200 to move relative to the box door 110 under the drive of the traction assembly 310, as Figure 10 and Figure 11 shown, the sliding door assembly 320 includes: a base 321, a first slider 322, a second slider 323, a guide member 330, and a connecting member 324.

[0117] Wherein, 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 arranged 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 arranged on the second guide rail 3212 and is connected to the cabinet door 200; the guide member 330 is arranged on the base 321, the connecting member 324 is wound around the guide member 330, and both ends of the connecting member 324 are respectively connected to the first slider 322 and the second slider 323; during the opening or closing process of the box door 110, 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.

[0118] Specifically, as Figure 10 and Figure 11 shown, the first guide rail 3211 is located at the top of the base 321 and provides a sliding track for the first slider 322. The second guide rail 3212 is located at the bottom of the base 321 and is parallel or at a certain angle to the first guide rail 3211, providing a sliding track for the second slider 323. The first slider 322 is slidably arranged on the first guide rail 3211 for driving connection with the box body 500. The second slider 323 is slidably arranged on the second guide rail 3212 for connection with the cabinet door 200. The connecting member 324 can be a connecting component such as a traction rope or a transmission belt. The connecting member 324 is wound around the guide member 330, and both ends of the connecting member 324 are respectively connected to the first slider 322 and the second slider 323.

[0119] When the first slider 322 is driven to move on the first guide rail 3211, since both ends of the connecting member 324 are respectively fixed to the first slider 322 and the second slider 323, and the connecting member 324 is wound around the guiding member 330, by reasonably setting the extending direction of the connecting member 324, the connecting member 324 will drive the second slider 323 to move in the opposite direction on the second guide rail 3212. This characteristic of synchronous reverse movement enables the cabinet door 200 to slide relative to the width direction of the cabinet body 500 when the first slider 322 is in transmission connection with the cabinet body 500 and the second slider 323 is connected to the cabinet door 200.

[0120] Further, in one embodiment, as Figure 10 and Figure 11 shown, the connecting member 324 is a rope, and the guiding member 330 is a support shaft; the support shaft is connected to the base 321 and is located between the first guide rail 3211 and the second guide rail 3212. The rope is wound around the support shaft, and both ends of the rope are respectively connected to the first slider 322 and the second slider 323.

[0121] In this embodiment, the guiding member 330 is specifically embodied as a support shaft. The support shaft is firmly connected to the base 321 and is generally located at the central position between the first guide rail 3211 and the second guide rail 3212 (the actual position can be adjusted according to design requirements). The main function of the support shaft is to provide a stable fulcrum for the rope to wind around it, thereby guiding the movement direction of the rope and ensuring that the first slider 322 and the second slider 323 can move synchronously and in the reverse direction along a predetermined trajectory. Both ends of the rope are respectively connected to the first slider 322 and the second slider 323. As a flexible but strong connecting material, the rope is very suitable for transmitting the movement and force between the two sliders. The rope is wound around the support shaft. This winding method enables the rope to slide along the support shaft and stretch or contract accordingly when the first slider 322 moves on the first guide rail 3211, thereby driving the second slider 323 to move in the opposite direction on the second guide rail 3212. The winding method of the rope may adopt a single loop, multiple loops or other complex winding modes according to actual needs to achieve the best transmission effect. At the same time, fixing points or fixtures for connecting the rope are respectively provided on the first slider 322 and the second slider 323. These fixing points or fixtures should be designed to be strong enough to withstand the tensile force and shear force transmitted by the rope to ensure the stable movement of the sliders.

[0122] Further, in one embodiment, as Figure 10 and Figure 11As shown, there are two ropes, namely the first rope and the second rope; there are two support shafts, namely the first support shaft and the second support shaft; the first support shaft is connected to one side of the base 321, the second support shaft is connected to the other side of the base 321, the first rope is wound around the first support shaft, and the two ends of the first rope are respectively connected to one side of the first slider 322 and one side of the second slider 323. The second rope is wound around the second support shaft, and the two ends of the second rope are respectively connected to the other side of the first slider 322 and the other side of the second slider 323.

[0123] When the first slider 322 moves on the first guide rail 3211, it will pull the second slider 323 to move in the opposite direction on the second guide rail 3212 through the first rope. Similarly, the two ends of the second rope are respectively connected to the other side of the first slider 322 and the other side of the second slider 323, providing another independent path for the reverse movement between the two.

[0124] Since the two ropes are respectively wound around the two support shafts and independently connect the two sides of the first slider 322 and the second slider 323, they can transmit force and motion more evenly. This design helps to improve the problem of asynchronous movement of the sliders caused by uneven rope tension or deviation of the support shaft position.

[0125] In some embodiments, as Figure 10 and Figure 11 shown, when using a single rope to connect the first slider 322 and the second slider 323, according to the position of the support shaft, after the first slider 322 moves a certain distance on the first guide rail 3211, the second slider 323 will only move a short distance, and the two will not move synchronously throughout the process.

[0126] To ensure that the first slider 322 and the second slider 323 can move synchronously throughout the reverse movement, as Figure 10 and Figure 11 shown, one end of the first rope is connected to the front end of one side of the first slider 322, the other end of the first rope is connected to the front end of one side of the second slider 323, one end of the second rope is connected to the rear end of the other side of the first slider 322, and the other end of the second rope is connected to the rear end of the other side of the second slider 323.

[0127] Specifically, in this embodiment, as Figure 10 and Figure 11As shown, the first rope is wound around the first support shaft on the front side of the base 321. One end of the first rope is connected to a position slightly to the left of the front side of the first slider 322, and the other end of the first rope is connected to a position slightly to the left of the front side of the second slider 323. Correspondingly, the second rope is wound around the second support shaft on the rear side of the base 321. One end of the second rope is connected to a position slightly to the right of the rear side of the first slider 322, and the other end of the second rope is connected to a position slightly to the right of the rear side of the second slider 323.

[0128] With the above connection method, as Figure 10 and Figure 11 shown, when the first slider 322 moves to the right along the first guide rail 3211, although it is difficult for the first rope to pull the second slider 323 to move, the second rope can pull the second slider 323 to move in the opposite direction (to the left) along the second guide rail 3212. When the first slider 322 moves to the left, the first rope can pull the second slider 323 to move in the opposite direction (to the right).

[0129] 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 hinge plate by means of structures such as bolts. Exemplarily, a through hole is provided in the second rotating shaft fixing seat 313. During installation, an external bolt can be passed through the through hole and connected to the hinge plate, thereby fixing the second rotating shaft fixing seat 313 on the hinge plate.

[0130] Next, the base 321 can be fixed on the door 110 by means of structures such as bolts. Exemplarily, joint 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 joint plates 325. During installation, an external bolt can be passed through the through holes on the two joint plates 325 and connected to the door 110, thereby fixing the base 321 on the door 110.

[0131] 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, etc.

[0132] During actual use, as Figure 10 and Figure 11As shown, when the door 110 moves relative to the cabinet body 500 from the position closing the storage space towards the position opening the storage space, since the first rotating shaft fixing seat 312 follows the hinge seat and is fixed on the door 110, during the rotation of the door 110, the first slider 322 will move along the A direction on the first guide rail 3211. Correspondingly, the first slider 322 will pull the second slider 323 to move along the B direction on the second guide rail 3212 through the first connecting member 3241. Since the base 321 is fixedly connected to the door 110 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 110 along the B direction. Among them, the A direction is opposite to the B direction, and both the A direction and the B direction are parallel to the width direction of the door 110.

[0133] Correspondingly, when the door 110 moves relative to the cabinet body 500 from the position opening the storage space towards the position closing the storage space, during the rotation of the door 110, the first slider 322 will move along the direction opposite to the A 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 B 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 110 along the direction opposite to the B direction.

[0134] Furthermore, in another specific implementation manner, as Figures 12 to 14 shown, the base 321 is configured as a plate-like structure with a certain length. The first guide rail 3211 and the second guide rail 3212 are respectively arranged on both sides of the width direction of the base 321, and moreover, both 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 arranged on the first guide rail 3211, and the second slider 323 is slidably arranged on the second guide rail 3212.

[0135] In some embodiments, the traction assembly includes: a first connecting rod and a second connecting rod. The first end of the first connecting rod is rotatably arranged on the hinge 400, for example, arranged on the hinge plate of the hinge 400.

[0136] Among them, the first end of the first connecting rod is rotatably arranged within the installation area. For example, the first end of the first connecting rod is installed within the installation area through the rotating shaft fixing seat. The first end of the second connecting rod is rotatably connected to the second end of the first connecting rod; the second end of the second connecting rod is rotatably arranged on the door 110 and is meshed and connected to the tooth part on the first slider 322 through the gear arranged at the second end of the second connecting rod.

[0137] 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 cabinet body 500, and the second connecting rod can rotate relative to the door 110.

[0138] When the second end of the second connecting rod makes a circular motion with the cabinet door 110 with the hinge axis as the center, since the first end of the first connecting rod is offset from the hinge axis, the distance between the second end of the second connecting rod and the first end of the first connecting rod changes, while the position of the second end of the second connecting rod relative to the cabinet door 110 remains unchanged, which causes the second end of the second connecting rod to rotate around the cabinet door 110 and drives the second slider 323 to drive the cabinet door 200 to move along the width direction of the cabinet door 110.

[0139] In actual application, during the opening process of the door 110, the door 110 drives the second end of the second connecting rod to rotate relative to the hinge axis. Based on the staggered arrangement of the first end of the first connecting rod and the hinge axis, the distance between the first end of the first connecting rod and the second end of the second connecting rod increases, driving the second end of the second connecting rod to rotate clockwise relative to the door 110, thereby controlling the second slider 323 to drive the cabinet door 200 to move along the width direction of the door 110 in the direction away from the hinge 400, that is, to move to the left relative to the door 110, so as to avoid interference between the cabinet door 200 and the cabinet door 200 of the side cabinet; During the closing process of the door 110, the second end of the second connecting rod is driven to rotate relative to the hinge axis. Based on the staggered arrangement of the first end of the first connecting rod and the hinge axis, the distance between the first end of the first connecting rod and the second end of the second connecting rod is reduced, driving the second end of the second connecting rod to rotate counterclockwise relative to the door 110, thereby controlling the second slider 323 to drive the cabinet door 200 to move along the width direction of the door 110 toward the direction close to the hinge 400, that is, to move to the right side relative to the door 110. This ensures that when the door 110 is closed, the cabinet door 200 can avoid the cabinet door 200 of the cabinet on the side and reset the cabinet door 200.

[0140] In an optional embodiment, 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. The first guide rail and the second guide rail are a kind of track, and the first slider 322 and the second slider 323 are sliding members adapted to the corresponding guide rail and can slide along the corresponding guide rail; 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 arranged 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 arranged between the second slider 323 and the second guide rail.

[0141] Accordingly, the traction rod 311 may be constructed as an arc-shaped rod, one end of the traction rod 311 is rotatably connected to the first rotation shaft fixing seat 312 via a first rotation shaft, and the other end of the traction rod 311 is rotatably connected to the second rotation shaft fixing seat 313 via a second rotation shaft.

[0142] As a way to achieve this, Figure 13 and Figure 14As shown, a first clamping part is provided on the first rotating shaft fixing seat 312. The first clamping part includes two clamping plates arranged side by side at intervals. The two clamping plates are respectively provided with pin holes, and the first rotating shaft is inserted into the two pin holes at the same time. One end of the traction rod 311 can be placed between the two clamping plates, and the end of the traction rod 311 is rotatably connected to the first rotating shaft. Thus, the traction rod 311 can be rotatably connected to the first rotating shaft fixing seat 312. Moreover, the first rotating shaft fixing seat 312 can be fixedly connected to the first slider 322 by means such as welding.

[0143] Similarly, as Figure 12 and Figure 14 shown, a second clamping part is provided on the second rotating shaft fixing seat 313. The second clamping part also includes two clamping plates arranged side by side at intervals. The two clamping plates are respectively provided with pin holes, and the second rotating shaft is inserted into the two pin holes at the same time. The other end of the traction rod 311 can be placed between the two clamping plates, and the end of the traction rod 311 is rotatably connected to the second rotating shaft. Thus, the traction rod 311 can be rotatably connected to the second rotating shaft fixing seat 313.

[0144] The first slider 322 and the second slider 323 are connected to each other by a connecting member 324. When the first slider 322 moves, it can drive the second slider 323 to move in the opposite direction by means of the connecting member 324.

[0145] 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 hinge plate by means such as bolts. Exemplarily, a through hole is provided in the second rotating shaft fixing seat 313. During installation, an external bolt can be passed through the through hole and connected to the hinge plate, so as to fix the second rotating shaft fixing seat 313 on the hinge plate.

[0146] Then, the base 321 can be fixed on the box door 110 by means such as bolts. Exemplarily, a first receiving plate 326 and a second receiving plate 327 are respectively provided on both sides in the length direction of the base 321, and through holes are respectively provided on the first receiving plate 326 and the second receiving plate 327. During installation, an external bolt can be passed through the through holes on the first receiving plate 326 and the second receiving plate 327 and connected to the box door 110, so as to fix the base 321 on the box door 110.

[0147] 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 such as bolts or clamping structures.

[0148] During actual use, as Figure 12 and Figure 13As shown, when the door 110 moves relative to the box 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 follows the hinge seat and is fixed on the door 110, during the rotation of the door 110, the first slider 322 will move along the C direction on the first guide rail 3211. Correspondingly, the first slider 322 will pull the second slider 323 to move along the D direction on the second guide rail 3212 through the connecting member 324. Since the base 321 is fixedly connected to the door 110 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 110 along the D direction. Wherein, the C direction is opposite to the D direction, and both the C direction and the D direction are parallel to the width direction of the door 110.

[0149] Correspondingly, when the door 110 moves relative to the box body 500 from the position of opening the storage space towards the position of closing the storage space, during the rotation of the door 110, the first slider 322 will move along the direction opposite to the C 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 D direction on the second guide rail 3212 through the connecting member 324. At this time, the cabinet door 200 will move relative to the door 110 along the direction opposite to the D direction.

[0150] Further, in an embodiment, in order to ensure that the first slider 322 can effectively drive the second slider 323 to move in the reverse direction, as Figures 12 to 14 shown, the connecting member 324 includes: a first connecting member 3241 and a second connecting member 3242.

[0151] Wherein, the first connecting member 3241 bypasses one end of the base 321, and both ends are respectively connected to one end of the first slider 322 and the second slider 323; the second connecting member 3242 bypasses the other end of the base 321, and both ends are respectively connected to the other end of the first slider 322 and the second slider 323.

[0152] Exemplarily, the first connecting member 3241 can be a flexible rope. In the length direction of the base 321, one end of the first connecting member 3241 is connected to the first slider 322, and the other end is connected to the second slider 323 after bypassing one end of the base 321. That is, in the length direction of the base 321, the first connecting member 3241 bypasses one end of the base 321, and both ends thereof extend towards the first slider 322 and the second slider 323 respectively, and are respectively connected to the first slider 322 and the second slider 323.

[0153] Correspondingly, one end of the second connecting member 3242 is connected to the first slider 322, and the other end is connected to the second slider 323 after bypassing the other end of the base 321. That is, in the length direction of the base 321, the second connecting member 3242 bypasses the other end of the base 321, and its two ends are also respectively connected to the first slider 322 and the second slider 323.

[0154] 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.

[0155] Exemplarily, to ensure that the first connecting member 3241 and the second connecting member 3242 can normally pull the second slider 323 to move, as Figure 14 shown, a first roller 328 and a second roller 329 are respectively provided on both sides in the length direction of the base 321. The first roller 328 and the second roller 329 can respectively support the first connecting member 3241 and the second connecting member 3242.

[0156] Specifically, as Figure 14 shown, the number of the first rollers 328 is two. The two first rollers 328 are arranged at intervals in the width direction of the base 321. Moreover, the two first rollers 328 can be respectively rotatably provided on the first receiving plate 326. To facilitate receiving the first connecting member 3241, a receiving groove can be provided on the outer periphery of the first roller 328 along its circumferential direction. Thus, when installing the first connecting member 3241, the first connecting member 3241 can be placed in the receiving grooves of the two first rollers 328. Thereafter, when the first slider 322 pulls the second slider 323 by means of the first connecting member 3241, the first connecting member 3241 can drive the two first rollers 328 to rotate.

[0157] Similarly, the number of the second rollers 329 is two. The two second rollers 329 are arranged at intervals in the width direction of the base 321. Moreover, the two second rollers 329 can be respectively rotatably provided on the second receiving plate 327. To facilitate receiving the second connecting member 3242, a receiving groove can also be provided on the outer periphery of the second roller 329 along its circumferential direction. Thus, when installing the second connecting member 3242, the second connecting member 3242 can be placed in the receiving grooves of the two second rollers 329. Thereafter, when the first slider 322 pulls the second slider 323 by means of the second connecting member 3242, the second connecting member 3242 can drive the two second rollers 329 to rotate.

[0158] Thus, in the above setting method, the first roller 328 can support and position the first connecting member 3241, and the second roller 329 can support and position the second connecting member 3242. By means of the first roller 328 and the second roller 329, it can be avoided that the first connecting member 3241 and the second connecting member 3242 contact other components during the movement process, resulting in wear and consumption, and an effective protection effect can be achieved on the first connecting member 3241 and the second connecting member 3242.

[0159] In addition, as described above, a refrigeration device is further provided in this embodiment. The refrigeration device includes a box body 500 and the door body device described in the above embodiment. Among them, the box body 500 forms a storage space, and the box door 110 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.
