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

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

[0056] Among them, each door body assembly 100 includes a box door 110, a cabinet door 200 and a sliding door mechanism 300. The cabinet door 200 is slidably arranged on the outer side of the box door 110. The top 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 assembly 310 and a sliding door assembly 320. The traction assembly 310 is arranged on the hinge 400, and the sliding door assembly 320 is arranged between the box door 110 and the cabinet door 200. The traction assembly 310 is configured to drive the sliding door assembly 320 to act during the opening or closing process of the box door 110, thereby driving the cabinet door 200 to move in the width direction relative to the box door 110.

[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 devices such as refrigerators, freezers, ice makers, etc. Among them, the refrigeration device includes a box body 500, and a storage space is formed in the box body 500. Vegetables, fruits and other items 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 device, and the refrigeration device can perform refrigeration processing on the storage space.

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

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

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

[0062] To facilitate the description of the positional relationship between each component, in this embodiment, as Figure 3As shown, the box body 500 is generally configured as a cuboid structure with a certain height. The box body 500 can be placed on a horizontal plane. The box body 500 has a height direction, a width direction, and a thickness direction that are perpendicular to each other. Among them, the height direction of the box body 500 is parallel to the vertical direction, and the width direction and the thickness direction are located in the horizontal plane and are perpendicular to each other.

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

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

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

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

[0067] Furthermore, the cabinet door 200 can be a decorative door panel. The cabinet door 200 is configured as a flat plate-like structure with a certain thickness. The cabinet door 200 is connected to the outer side of the box door 110 facing away from the box body 500. When the refrigeration device is placed together with the cabinet in an embedded manner or directly placed in the cabinet, after the box door 110 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 facing away from the box door 110 can be flush with the outer wall surface of the cabinet.

[0068] In an actual use scenario, the outer wall surface of the cabinet door 200 can be selected to have the same material and shape as the outer wall surface of the cabinet, and the same decoration can be attached, so that the refrigeration device can have sufficient coordination with the cabinet and ensure aesthetics.

[0069] After the door body device in the present embodiment is installed on the cabinet body 500 of the refrigeration device, multiple door body components 100 can be arranged at intervals along the height direction of the cabinet body 500. When the cabinet door 110 in each door body component 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 cabinet door 110 in the width direction of the cabinet door 110. Thus, when the refrigeration device is placed in the cabinet in an embedded placement 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 cabinet door 110.

[0070] In one embodiment, as Figure 4 shown, the door body device and the cabinet body 500 are configured to be arranged in the installation space formed between the first cabinet body 510 and the second cabinet body 520; during the process of opening or closing the cabinet door 110, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the cabinet door 110, 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 process of opening or closing the cabinet door 110, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the cabinet door 110, so that the cabinet door 200 can avoid the side walls of the cabinet.

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

[0073] In practice, as Figure 4 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, multiple door body components 100 in the door body device can be arranged at intervals along the height direction of the cabinet body 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 in 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 body 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 body 510 and the second cabinet body 520, and the outer wall surfaces of the first cabinet body 510 and the second cabinet body 520 and the outer wall surface of the cabinet door 200 facing away from the cabinet door 110 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 110 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 provided on the outer side of the cabinet door 110 of each door body assembly 100, and the cabinet door 200 can move relative to the cabinet door 110. Optionally, when the cabinet door 110 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 110 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 110 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 110 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 walls of the cabinet body.

[0077] Furthermore, 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 assembly 310 and a sliding door assembly 320. The traction assembly 310 can be arranged on the hinge 400, the sliding door assembly 320 can be arranged on the cabinet door 110, and the sliding door assembly 320 can also be connected to the cabinet door 200. During the rotation of the cabinet door 110 relative to the cabinet body 500, the traction assembly 310 can drive the sliding door assembly 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 body 500, during the rotation of the cabinet door 110 relative to the cabinet body 500, the traction assembly 310 can apply a pulling force to the sliding door assembly 320, and then the sliding door assembly 320 drives the cabinet door 200 to move based on this pulling force.

[0079] Thus, when the door body device in the present embodiment is installed on the cabinet body 500 of the refrigeration device, a plurality of door body assemblies 100 can be arranged at intervals along the height direction of the cabinet body 500. Each door body assembly 100 can at least correspond to a storage space of the cabinet body 500. During the rotation of the cabinet door 110 in each door body assembly 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 110 under the drive of the traction assembly 310. Thus, when the refrigeration device is placed in the cabinet in an embedded manner, without affecting the coordination, aesthetics and user experience, the cabinet door 200 can be prevented from interfering with the cabinet during the opening of the cabinet door 110.

[0080] Furthermore, in one embodiment, asFigure 3 As shown, the hinge 400 includes a first hinge 410 and a second hinge 430. The first hinge 410 is disposed on the top wall of the cabinet 500, and the second hinge 430 is disposed on the front surface of the cabinet 500. The door device includes a first cabinet door 111 and a second cabinet door 112. The top of the first cabinet door 111 is rotatably connected to the cabinet 500 through the first hinge 410, and the top of the second cabinet door 112 is rotatably connected to the cabinet 500 through the second hinge 430.

[0081] Exemplarily, the number of the hinges 400 is at least two. The hinge 400 at least includes a first hinge 410 and a second hinge 430. Among them, the first hinge 410 is used for fixedly disposed on the top wall of the cabinet 500, and the second hinge 430 is used for fixedly disposed on the front surface of the cabinet 500. Both the first hinge 410 and the second hinge 430 can be used to connect the cabinet door 110.

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

[0083] The top of the first cabinet door 111 can be rotatably connected to the cabinet 500 through the first hinge 410, and the top of the second cabinet door 112 can be rotatably connected to the cabinet 500 through the second hinge 430.

[0084] In practical applications, according to different refrigeration requirements, different refrigeration equipment cabinets 500 will be provided with different numbers of storage spaces. These storage spaces are spaced apart in the height direction of the cabinet 500. Some storage spaces are for refrigeration, and some storage spaces are for freezing. Correspondingly, in order to be able to selectively close these storage spaces, the number of cabinet doors 110 can be multiple, and each cabinet door 110 at least corresponds to the position of one of the storage spaces.

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

[0086] For another example, the cabinet 500 may be provided with three storage spaces at intervals in the vertical direction, namely a first space, a second space and a 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 a first cabinet door 111 and a second cabinet door 112. Among them, the first cabinet door 111 corresponds to the positions of the first space and the second space one by one, and the second cabinet door 112 corresponds to the position of 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 independently control the opening and closing state of the storage space. Or, according to requirements, each cabinet door 110 can also correspond to multiple adjacent storage spaces. At this time, the cabinet door 110 can simultaneously control the opening and closing states of the multiple storage spaces.

[0088] Further, in one embodiment, as Figure 5 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 rest protrudes from the top wall towards the first cabinet door 111. The first hinge shaft 412 extends downward from the part of the first hinge plate 411 protruding from the top wall. The top of the first cabinet door 111 is hinged to the first hinge shaft 412. The traction assembly 310 is provided on one of the first hinge plate 411 and the first hinge shaft 412.

[0089] 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 which are connected to each other. The first fitting part is provided with a plurality of mounting holes, and the first hinge shaft 412 is fixedly arranged on the first protruding part by means of welding or threaded connection.

[0090] 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 made to correspond to the positions of 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 first cabinet door 111, and moreover, the first hinge shaft 412 can extend downward along the height direction of the cabinet 500.

[0091] Based on this, when installing the installation box door 110, hinge holes can be set in advance at the top of the first box door 111, and then the first hinge shaft 412 can be inserted into the hinge holes. Thus, the installation of the first box door 111 can be achieved.

[0092] Moreover, a sliding door mechanism 300 is connected to the box door 110 corresponding to the first hinge 410. The traction component 310 in the sliding door mechanism 300 can be arranged on the first hinge plate 411 or on the first hinge shaft 412.

[0093] For example, as Figure 5 shown, in one embodiment, a vertical plate 413 is provided on the first hinge plate 411. The vertical plate 413 extends downward along the thickness direction of the first hinge plate 411, and an installation hole is provided on the vertical plate 413.

[0094] As Figure 8 shown, during actual installation, the first hinge plate 411 is fixed to the top wall of the box body 500, the first box door 111 is rotatably connected to the first hinge shaft 412, and part of the structure of the traction component 310 can be connected to the vertical plate 413 by means of bolts.

[0095] Furthermore, in one embodiment, as Figure 6 shown, the second hinge 430 includes a second hinge plate 431, a second hinge shaft 432, and a third hinge shaft 433. The second 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 arranged at an angle with the mounting plate 4311, the connecting plate 4312 has an opposite first side and second side, the second hinge shaft 432 is arranged on the first side, the bottom of the first box door 111 is hinged to the second hinge shaft 432, the third hinge shaft 433 is arranged on the second side, and the top of the second box door 112 is hinged to the second hinge shaft 432. The traction component 310 is arranged on one of the second hinge plate 431 and the third hinge shaft 433.

[0096] Exemplarily, the second hinge plate 431, the second hinge shaft 432, and the third hinge shaft 433 can be made of a metal material or a non-metal material with a certain structural strength. The second hinge plate 431 includes a mounting plate 4311 and a connecting plate 4312 connected to each other. The connecting plate 4312 is substantially perpendicular to the mounting plate 4311, and 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, and then, the connecting plate 4312 can be bent relative to the mounting plate 4311 by means of stamping and folding.

[0097] On both sides of the connecting plate 4312 in the thickness direction are a first side and a second side respectively. The second hinge shaft 432 is fixedly connected to the first side, and the third hinge shaft 433 is fixedly connected to the second side.

[0098] During actual production and manufacturing, the second hinge shaft 432 and the third hinge shaft 433 can be fixedly connected to the connecting plate 4312 by welding respectively. Or, the second hinge shaft 432 and the third hinge shaft 433 can be constructed as an integral part in the shape of a long bar. The connecting plate 4312 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 4312 are respectively formed as the second hinge shaft 432 and the third hinge shaft 433.

[0099] During actual installation, as Figure 9 shown, according to the installation position of the box door 110, a plurality of threaded holes can be set in advance on the front surface of the box body 500. For example, as Figure 3 shown, a plurality of threaded holes are set at the position corresponding to the gap between the first box door 111 and the second box door 112 on the front surface of the box body 500. Then, the mounting holes on the mounting plate 4311 of the second hinge plate 431 are aligned with the positions of the threaded holes, and then the mounting plate 4311 is fixed to the front surface of the box body 500 with the help of bolts. At this time, the connecting plate 4312 extends in the direction towards the box door 110. At the same time, the second hinge shaft 432 extends upward along the height direction of the box body 500, and the third hinge shaft 433 extends downward along the height direction of the box body 500.

[0100] Based on this, when installing the box door 110, a hinge hole can be set in advance at the bottom of the first box door 111, and, a hinge hole can be set in advance at the top of the second box door 112. Then, the second hinge shaft 432 can be inserted into the hinge hole at the bottom of the first box door 111, and, the third hinge shaft 433 can be inserted into the hinge hole at the top of the second box door 112. Thus, the installation of the first box door 111 and the second box door 112 can be realized.

[0101] In addition, the second hinge 430 can be provided with at least one traction component 310. For example, the first box door 111 or the second box door 112 is connected with a sliding door mechanism 300, and the traction component 310 in this sliding door mechanism 300 can be connected to the second hinge plate 431, the second hinge shaft 432 or the third hinge shaft 433. Or, the second hinge 430 can be provided with two traction components 310. For example, the first box door 111 and the second box door 112 are respectively connected with a sliding door mechanism 300, and the two traction components 310 in these two sliding door mechanisms 300 can be connected to the second hinge plate 431, the second hinge shaft 432 or the third hinge shaft 433 according to the usage requirements.

[0102] In one embodiment, Figure 9 As shown, the second box door 112 is provided with a sliding door mechanism 300 , and the traction assembly 310 in the sliding door mechanism 300 can be fixedly connected to the mounting plate 4311 via bolts.

[0103] Further, in one embodiment, the central axis of the second hinge shaft 432 and the central axis of the third hinge shaft 433 are arranged to coincide with each other.

[0104] It can be understood that by setting the central axis of the second hinge shaft 432 and the central axis of the third hinge shaft 433 to be colinear, the first door 111 and the second door 112 can rotate around the same rotation axis, thereby making the connection structure between the door 110 and the box body 500 more reasonable and easier to install.

[0105] Further, in one embodiment, if Figure 7 As shown, the hinge 400 also includes a third hinge 420, the third hinge 420 includes a third hinge plate 421 and a fourth hinge shaft 422, the third hinge plate 421 includes a support plate 4211 and an extension plate 4212, the support plate 4211 is installed on the front of the box body 500, the extension plate 4212 is connected to the side of the support plate 4211 away from the front of the box body 500, the support plate 4211 and the extension plate 4212 are arranged at an angle, the fourth hinge shaft 422 is arranged on the top surface of the extension plate 4212 and extends upward, and the bottom of the second box door 112 is hinged to the fourth hinge shaft 422.

[0106] Similarly, the third hinge plate 421 and the fourth hinge shaft 422 can also be made of metal or non-metallic materials with a certain structural strength. The third hinge plate 421 includes a support plate 4211 and an extension plate 4212 that are connected to each other. The extension plate 4212 is roughly perpendicular to the support plate 4211. The two can be integrally formed by stamping or the like. The support plate 4211 is provided with a plurality of mounting holes. The fourth hinge shaft 422 is fixed on the extension plate 4212 by welding or threaded connection.

[0107] During actual installation, multiple threaded holes can be set in advance on the front side of the box 500 and near the bottom, and then one side of the support plate 4211 in the thickness direction is attached to the front side of the box 500, and the mounting holes on the support plate 4211 correspond to the positions of the threaded holes, and then the support plate 4211 is fixed to the front side of the box 500 with the help of bolts. The extension plate 4212 is connected to the other side of the support plate 4211 in the thickness direction and extends in the direction of the second box door 112. Moreover, the fourth hinge shaft 422 extends upward along the height direction of the box 500.

[0108] Based on this, when installing the box door 110, hinge holes can be set in advance at the bottom of the second box door 112, and then the fourth hinge shaft 422 is inserted into the hinge holes, thereby enabling the installation of the second box door 112.

[0109] In a specific embodiment, as Figure 3 shown, the box body 500 is provided with two storage spaces at intervals along its height direction. A first hinge 410 is provided at the top of the box body 500, a second hinge 430 is provided in the middle of the box body 500 and approximately at a position between the two storage spaces, and a third hinge 420 is provided at the bottom of the box body 500. The door device includes two door components 100, and 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 first hinge shaft 412 of the first hinge 410, the bottom of the first box door 111 is hinged to the second hinge shaft 432 of the second hinge 430, the top of the second box door 112 is hinged to the third hinge shaft 433 of the second hinge 430, and the bottom of the second box door 112 is hinged to the fourth hinge shaft 422 of the third 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] Furthermore, in an 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 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, thereby driving 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, 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 box body 500 by means of structures such as bolts. The door 110 can be provided with threaded holes 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 door 110, so as to realize the rotational connection of the 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 the two 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.

[0115] During actual use, when the door 110 rotates relative to the box body 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 door 110 in the width direction of the door 110.

[0116] Furthermore, in one embodiment, in order to enable the sliding door assembly 320 to effectively drive the cabinet door 200 to move relative to the 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, and a connecting member 324.

[0117] 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 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 two ends of the connecting member 324 are respectively connected to the first slider 322 and the second slider 323.

[0118] During the opening or closing process of the 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.

[0119] Exemplarily, the base 321 has a first guide rail 3211 and a second guide rail 3212 arranged side by side and spaced apart. 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 a 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.

[0120] As a specific implementation manner, as Figure 10 and Figure 11 shown, the opposite two sides in the thickness direction of the base 321 are a first side and a second side respectively. U-shaped grooves are formed on the first side and the second side respectively. 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.

[0121] Considering the requirements in practical applications, limiting 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 limiting 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.

[0122] Correspondingly, the traction rod 311 is configured as a long straight rod. One end of the traction rod 311 is rotatably connected to the first rotating shaft fixing seat 312 via a first rotating shaft, and the other end is rotatably connected to the second rotating shaft fixing seat 313 via a second rotating shaft. The second rotating shaft fixing seat 313 is fixedly connected to the first slider 322.

[0123] As an implementation manner, as Figure 11 shown, the first rotating shaft fixing seat 312 includes a first vertical plate and a first horizontal plate. The first vertical plate and the first horizontal plate are connected to each other and form an L-shaped structure. The first horizontal plate is provided with a shaft hole, and a first rotating shaft is inserted into the shaft hole. One end of the traction rod 311 is rotatably connected to the first rotating shaft, so as to be fixedly connected to the first rotating shaft fixing seat 312. The first vertical plate can be fixedly connected to the first slider 322 by means such as welding.

[0124] Similarly, asFigure 10 and Figure 11 As shown in Figure 11 , the second rotating shaft fixing seat 313 includes a second vertical plate and a second horizontal plate. The second vertical plate and the second horizontal plate are connected to each other and form an L-shaped structure. The second horizontal plate is provided with a shaft hole, and a second rotating shaft can be inserted into the shaft hole. The other end of the traction rod 311 is rotatably connected to the second rotating shaft, so as to be rotatably connected to the second rotating shaft fixing seat 313.

[0125] To ensure that the first slider 322 and the second slider 323 can move synchronously and in opposite directions, exemplarily, the connecting member 324 includes a first connecting member 3241 and a second connecting member 3242, and the first connecting member 3241 and the second connecting member 3242 are configured as flexible ropes. In the length direction of the base 321, the first connecting member 3241 bypasses the end of the base 321, and its two ends respectively enter the first guide rail 3211 and the second guide rail 3212, and are respectively connected to the first slider 322 and the second slider 323. Correspondingly, the second connecting member 3242 bypasses the other end of the base 321, and its two ends also respectively enter the first guide rail 3211 and the second guide rail 3212, and are respectively connected to the first slider 322 and the second slider 323. At this time, the two ends of the first connecting member 3241 are respectively connected to the two ends of the second connecting member 3242 via the first slider 322 and the second slider 323, and form a substantially annular structure.

[0126] 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, the second vertical plate in the second rotating shaft fixing seat 313 is provided with a through hole. During installation, an external bolt can be passed through the through hole and connected to the hinge plate, so as to fix the second vertical plate on the hinge plate.

[0127] Then, the base 321 can be fixed on the door 110 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, an external bolt can be passed through the through holes on the two engaging plates 325 and connected to the door 110, so as to fix the base 321 on the door 110.

[0128] 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.

[0129] During actual use, as Figure 10 and Figure 11As shown, when the door 110 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 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.

[0130] Correspondingly, when the door 110 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 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.

[0131] Furthermore, in yet another specific implementation, 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.

[0132] 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, it is arranged on the hinge plate of the hinge 400.

[0133] 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 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 arranged on the door 110 and is meshed and connected to the tooth portion on the first slider 322 through a gear arranged at the second end of the second connecting rod.

[0134] 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.

[0135] When the second end of the second link rotates in a circular motion around the hinge axis with the door 110, since the first end of the first link is misaligned with the hinge axis, the distance between the second end of the second link and the first end of the first link changes, while the position of the second end of the second link relative to the door 110 remains unchanged. As a result, the second end of the second link rotates around the door 110 and drives the second slider 323 to drive the cabinet door 200 to move along the width direction of the door 110.

[0136] In practical applications, during the opening process of the door 110, the door 110 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 door 110. Then, the second slider 323 is controlled to drive the cabinet door 200 to move along the width direction of the door 110 away from the hinge 400, that is, move to the left relative to the door 110. In this way, interference between the cabinet door 200 and the cabinet door 200 on the side cabinet can be avoided; during the closing process of the door 110, the door 110 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 door 110. Then, the second slider 323 is controlled to drive the cabinet door 200 to move along the width direction of the door 110 towards the hinge 400, that is, move to the right relative to the door 110. In this way, it can be ensured that the cabinet door 200 can avoid the cabinet door 200 on the side cabinet when the door 110 is closed, and the cabinet door 200 can be reset.

[0137] In an alternative 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.

[0138] Correspondingly, the towing rod 311 can be configured as an arc-shaped rod. One end of the towing rod 311 is rotatably connected to the first rotating shaft fixing seat 312 via the first rotating shaft, and the other end is rotatably connected to the second rotating shaft fixing seat 313 via the second rotating shaft.

[0139] As a way of implementation, such as Figure 13 and Figure 14As shown, a first clamping portion is provided on the first rotating shaft fixing seat 312. The first clamping portion 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 of welding or the like.

[0140] Similarly, as Figure 12 and Figure 14 shown, a second clamping portion is provided on the second rotating shaft fixing seat 313. The second clamping portion 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.

[0141] The first slider 322 and the second slider 323 are connected to each other by a connecting member 324. The first slider 322 can drive the second slider 323 to move in the opposite direction by means of the connecting member 324 during the movement.

[0142] 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, so as to fix the second rotating shaft fixing seat 313 on the hinge plate.

[0143] Then, the base 321 can be fixed on the box door 110 by means of structures 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.

[0144] 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 clamping structures or the like.

[0145] During actual use, as Figure 12 and Figure 13As shown, when the box door 110 moves relative to the box body 500 from the position closing the storage space towards the position opening the storage space, since the first rotating shaft fixing seat 312 is fixed on the box door 110 following the hinge seat, during the rotation of the box 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 piece 324. Since the base 321 is fixedly connected to the box 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 box 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 box door 110.

[0146] Correspondingly, when the box door 110 moves relative to the box body 500 from the position opening the storage space towards the position closing the storage space, during the rotation of the box 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 piece 324. At this time, the cabinet door 200 will move relative to the box door 110 along the direction opposite to the D direction.

[0147] Wherein, the first guide rail and the second guide rail are used as a kind of track, and the first slider 322 and the second slider 323 are sliding parts adapted to the corresponding guide rails and can slide along the corresponding guide rails; in addition, the sliding fit between the first slider 322 and the first guide rail should at least include the case where there are balls arranged between the first slider 322 and the first guide rail, and the sliding fit between the second slider 323 and the second guide rail should at least include the case where there are balls arranged between the second slider 323 and the second guide rail.

[0148] 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 piece 324 includes: a first connecting piece 3241 and a second connecting piece 3242.

[0149] Wherein, the first connecting piece 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 piece 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.

[0150] Exemplarily, the first connecting member 3241 may 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 its two ends extend towards the first slider 322 and the second slider 323 respectively and are connected to the first slider 322 and the second slider 323 respectively.

[0151] 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 connected to the first slider 322 and the second slider 323 respectively.

[0152] 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.

[0153] Exemplarily, in order 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 arranged 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.

[0154] 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 arranged on the first receiving plate 326. In order to facilitate receiving the first connecting member 3241, a receiving groove extending along its circumferential direction can be arranged on the outer circumference of the first roller 328. 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.

[0155] 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 rotatably arranged on the second receiving plate 327 respectively. For the convenience of receiving the second connecting member 3242, a receiving groove extending along the circumferential direction can also be arranged on the outer circumference of the second roller 329. 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.

[0156] Thus, in the above setting mode, the first roller 328 can play a role in supporting and limiting the first connecting member 3241, and the second roller 329 can play a role in supporting and limiting 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 moving process and cause wear and consumption, and an effective protection effect can be achieved on the first connecting member 3241 and the second connecting member 3242.

[0157] 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.
