[0053] Specifically, as Figure 3 andFigure 4 As shown, the door device in this embodiment includes a plurality of door components 100, and the plurality of door components 100 are arranged side by side in the height direction of the cabinet 500.

[0054] Among them, each door 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 box door 110 is rotatably connected to the cabinet 500 through two hinges 400. The number of sliding door mechanisms 300 is the same as the number of hinges 400 and they correspond one by one. 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 corresponding 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, thereby driving the cabinet door 200 to move relative to the width direction of the box door 110.

[0055] 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.

[0056] It can be understood that the door device in this embodiment can be used in refrigeration equipment such as refrigerators, freezers, ice makers, etc. Among them, the refrigeration equipment includes a cabinet 500, and the cabinet 500 forms a storage space, and items such as vegetables and fruits that need to be refrigerated or frozen can be placed in the storage space. Optionally, a refrigeration device and the like are also arranged in the cabinet 500 of the refrigeration equipment, and the refrigeration device can perform refrigeration treatment on the storage space.

[0057] In this embodiment, the door device includes a plurality of door components 100. For example, the number of door components 100 can be two, three or four, and the plurality of door components 100 are arranged at intervals in the height direction of the cabinet 500. Exemplarily, Figure 3 the door device shown in [the figure] includes two door components 100.

[0058] Furthermore, each door component 100 includes a box door 110, a cabinet door 200 and at least one sliding door mechanism 300.

[0059] Among them, the plurality of door components 100 include two door components. For example, the two door components are a first door component and a second door component respectively. The first door component is located above the second door component, and the box doors 110 of the first door component and the second door component can be respectively rotatably connected to the cabinet 500 through hinges 400.

[0060] The first door body assembly is correspondingly connected with two hinges 400. The door 110 in the first door body assembly is rotatably connected to the box body 500 via the hinge axes of the two hinges 400. The hinge axis of one of the hinges 400 is located at the top of the door 110 in the first door body assembly, and the hinge axis of the other hinge 400 is located at the bottom of the door 110 in the first door body assembly. At the same time, traction assemblies 310 are respectively arranged on the two hinges.

[0061] The second door body assembly is correspondingly connected with two hinges 400. The door 110 in the second door body assembly is rotatably connected to the box body 500 via the hinge axes of the two hinges 400. The hinge axis of one of the hinges 400 is located at the top of the door 110 in the second door body assembly, and the hinge axis of the other hinge 400 is located at the bottom of the door 110 in the second door body assembly. At the same time, traction assemblies 310 are respectively arranged on the two hinges.

[0062] In this embodiment, the door 110 can be used to open or close the storage space in the box body 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.

[0063] For the convenience of describing the positional relationship between various components, in this embodiment, as Figure 3 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.

[0064] A storage space is arranged inside the box body 500. An opening is arranged on the side of the box body 500 in the thickness direction, and the opening communicates with the storage space. The door 110 is connected to the side of the box body 500 in the thickness direction where the opening is arranged. The door 110 extends along the width direction of the box body 500. The door 110 is connected with a hinge 400 on one side in the width direction of the box body 500. The door 110 can be rotatably connected to the box body 500 via the hinge 400, so as to ensure that the door 110 can open or close the storage space of the box body 500.

[0065] Moreover, the side of the box body 500 where the door 110 is installed is the front side, that is, the door 110 is installed on the front side of the box body 500.

[0066] The box door 110 is generally configured as a flat plate 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 perpendicular to each other. One side of the box door 110 in the width direction can be rotatably connected to the box body 500 via a hinge 400. For example, as Figure 3 shown, a hinge 400 is connected to the right side of the box door 110 in the width direction of the box body 500, and the box door 110 can be rotatably connected to the box body 500 via this hinge 400.

[0067] Moreover, when the box door 110 is in the position 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.

[0068] 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 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.

[0069] 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 to make the refrigeration device have sufficient coordination with the cabinet and ensure the aesthetics.

[0070] After the door body device in this embodiment is installed on the box body 500 of the refrigeration device, multiple door body components 100 can be arranged at intervals along the height direction of the box body 500. When each box door 110 in the door body component 100 can rotate to open or close the storage space of the box body 500 relative to the box body 500, the sliding door mechanism 300 can drive the cabinet door 200 to move relative to the box door 110 in the width direction of the box door 110. Thus, when the refrigeration device is placed in the cabinet in an embedded placement method, 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 box door 110.

[0071] In one embodiment, as Figure 4As shown, the door device and the cabinet 500 are configured to be arranged in the installation space formed between the first cabinet 510 and the second cabinet 520; when the cabinet door 110 is opened or closed, 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 avoids the side walls of the first cabinet 510 and the second cabinet 520;

[0072] Alternatively, the door device and the box body 500 are configured to be set in the cabinet; during the opening or closing process of the box door 110, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the box door 110 so that the cabinet door 200 avoids the side wall of the cabinet.

[0073] It can be understood that the refrigeration device includes a door device and a box body 500 .

[0074] In practice, Figure 4 As shown, when the refrigeration equipment having the door device and the cabinet 500 is placed between the adjacent first cabinet 510 and the second cabinet 520, the plurality of door assemblies 100 in the door device can be arranged at intervals along the height direction of the cabinet 500, and the outer side of the cabinet door 110 in each door assembly 100 is provided with a cabinet door 200, 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 a state of closing the storage space of the cabinet 500, the outer wall surface of the cabinet door 200 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 away from the cabinet door 110 are in the same direction in the thickness direction of the cabinet 500.

[0075] 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 avoids the side walls of the first cabinet body 510 and the second cabinet body 520 .

[0076] Alternatively, after the refrigeration device is placed in the cabinet, a cabinet door 200 may be provided on the outside of the cabinet door 110 of each door assembly 100, and the cabinet door 200 may be movable relative to the cabinet door 110. Optionally, when the cabinet door 110 is in a state of closing the storage space of the cabinet 500, the outer wall surface of the cabinet door 200 that is away from the cabinet door 110 may 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 that is away from the cabinet door 110 are in the same direction in the thickness direction of the cabinet 500.

[0077] 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 allow the cabinet door 200 to avoid the side wall of the cabinet body.

[0078] Further, in the sliding door mechanism 300 of the present embodiment, as Figure 11 and Figure 13 shown, the sliding door mechanism 300 includes a traction assembly 310 and a sliding door assembly 320 connected to each other. The traction assembly 310 can be disposed on the hinge 400, the sliding door assembly 320 can be disposed 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.

[0079] 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.

[0080] 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 correspond to at least one 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. Therefore, when the refrigeration device is placed in an embedded manner in a cabinet, without affecting the coordination, aesthetics and user experience, interference between the cabinet door 200 and the cabinet can be avoided during the opening of the cabinet door 110.

[0081] Further, in one embodiment, as Figure 3 shown, the hinge 400 includes a first hinge 410, a second hinge 430 and a third hinge 420. The first hinge 410 is disposed on the top wall of the cabinet body 500, and the second hinge 430 and the third hinge 420 are disposed on the front of the cabinet body 500. The door body 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 body 500 through the first hinge 410, the bottom of the first cabinet door 111 and the top of the second cabinet door 112 are rotatably connected to the cabinet body 500 through the second hinge 430, and the bottom of the second cabinet door 112 is rotatably connected to the cabinet body 500 through the third hinge 420.

[0082] Exemplarily, the number of hinges 400 is at least three. The hinge 400 at least includes a first hinge 410, a second hinge 430, and a third hinge 420. Among them, the first hinge 410 is used to be fixedly arranged on the top wall of the box body 500, and the second hinge 430 and the third hinge 420 are used to be fixedly arranged on the front of the box body 500. Both the first hinge 410 and the second hinge 430 can be used to connect the box door 110.

[0083] The door device includes two door components 100, namely a first door component and a second door component. The first door component includes a first box door 111, and the second door component includes a second box door 112. As Figure 3 shown, the first box door 111 and the second box door 112 are arranged at intervals in the height direction of the box body 500.

[0084] The top of the first box door 111 can be rotatably connected to the box body 500 through the first hinge 410. The bottom of the first box door 111 and the top of the second box door 112 can be rotatably connected to the box body 500 through the second hinge 430. The bottom of the second box door 112 can be rotatably connected to the box body 500 through the third hinge 420.

[0085] In practical applications, according to different refrigeration requirements, different numbers of storage spaces will be set in the box body 500 of different refrigeration devices. These storage spaces are arranged at intervals in the height direction of the box body 500. Some storage spaces are for refrigeration, and some storage spaces are for freezing. Correspondingly, in order to be able to close these storage spaces specifically, the number of box doors 110 can be multiple, and each box door 110 at least corresponds to the position of one of the storage spaces.

[0086] For example, as Figure 3 shown, the box body 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 box doors 110 is two, namely a first box door 111 and a second box door 112. These two box doors 110 correspond one-to-one to the positions of the two storage spaces. At this time, the two storage spaces can be independently opened or closed through the two box doors 110 respectively.

[0087] For another example, the box body 500 can 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 box doors 110 is two, namely a first box door 111 and a second box door 112. Among them, the first box door 111 corresponds one-to-one to the positions of the first space and the second space at the same time, and the second box 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 box door 111, and the opening and closing state of the third space can be independently controlled by using the second box door 112.

[0088] It can be understood that in this embodiment, each door 110 can correspond to a single storage space. In this case, the door 110 can independently control the opening and closing state of the storage space. Alternatively, according to requirements, each door 110 can also correspond to a plurality of adjacent storage spaces. In this case, the door 110 can simultaneously control the opening and closing states of the plurality of storage spaces.

[0089] Furthermore, 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 remaining part projects from the top wall towards the door 110. The first hinge shaft 412 extends downward from the part of the first hinge plate 411 that projects from the top wall. The top of the first door 111 is hinged to the first hinge shaft 412, and the first traction assembly 310 is disposed on one of the first hinge plate 411 and the first hinge shaft 412.

[0090] Exemplarily, the first hinge plate 411 and the first hinge shaft 412 can be made of a metal or non-metal material with a certain structural strength. The first hinge plate 411 includes a first fitting portion and a first protruding portion that are connected to each other. The first fitting portion is provided with a plurality of mounting holes, and the first hinge shaft 412 is fixedly disposed on the first protruding portion by means of welding or threaded connection, etc.

[0091] 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 portion 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 portion are aligned with the threaded holes. Then, the first fitting portion is fixed to the top wall of the cabinet 500 by means of bolts. At this time, the first fitting portion can cover and fit to the top wall of the cabinet 500, the first protruding portion can project from the top wall towards the first door 111, and moreover, the first hinge shaft 412 can extend downward along the height direction of the cabinet 500.

[0092] Based on this, when installing the door 110, a hinge hole can be provided in advance on the top of the first door 111. Then, the first hinge shaft 412 is inserted into the hinge hole, and thus, the installation of the first door 111 can be achieved.

[0093] Moreover, a sliding door mechanism 300 is connected to the top of the first door 111, and the traction assembly 310 in the sliding door mechanism 300 can be disposed on the first hinge plate 411 or on the first hinge shaft 412.

[0094] For example, as Figure 5As 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 mounting holes are provided on the vertical plate 413.

[0095] 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 in the traction assembly 310 can be connected to the vertical plate 413 by bolts.

[0096] Further, 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 disposed at an angle to the mounting plate 4311. The connecting plate 4312 has a first side and a second side opposite to each other. The second hinge shaft 432 is disposed on the first side, and the bottom of the first box door 111 is hinged to the second hinge shaft 432. The third hinge shaft 433 is disposed on the second side, and the top of the second box door 112 is hinged to the third hinge shaft 433.

[0097] Wherein, the second traction assembly 310 and the third traction assembly 310 are both disposed on one of the mounting plate 4311 and the connecting plate 4312, or are respectively disposed on the second hinge shaft 432 and the third hinge shaft 433; alternatively, the second traction assembly 310 is disposed on one of the mounting plate 4311 and the connecting plate 4312, and the third traction assembly 310 is disposed on one of the second hinge shaft 432 and the third hinge shaft 433.

[0098] 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 that are 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.

[0099] The two sides in the thickness direction of the connecting plate 4312 are the first side and the 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.

[0100] 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. Alternatively, 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.

[0101] During actual installation, as Figure 9 shown, multiple threaded holes can be set in advance on the front surface of the box body 500 according to the installation position of the box door 110. For example, as Figure 3 shown, multiple 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 by means of bolts. At this time, the connecting plate 4312 extends towards the direction of 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.

[0102] Based on this, when installing the box door 110, hinge holes can be set in advance at the bottom of the first box door 111, and hinge holes 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.

[0103] In addition, a sliding door mechanism 300 is connected to the bottom of the first box door 111. The traction assembly 310 in the sliding door mechanism 300 can be arranged on the mounting plate 4311 or the connecting plate 4312 in the second hinge plate 431, or can also be arranged on the second hinge shaft 432. A sliding door mechanism 300 is connected to the top of the second box door 112. The traction assembly 310 in the sliding door mechanism 300 can be arranged on the mounting plate 4311 or the connecting plate 4312 in the second hinge plate 431, or can also be arranged on the third hinge shaft 433. It can be understood that according to actual installation requirements, the two traction assemblies 310 can be arranged on the same structure or on different structures.

[0104] For example, as Figure 9As shown, a sliding door mechanism 300 is connected to the first box door 111 and the second box door 112 respectively. The traction components 310 in the two sliding door mechanisms 300 can be fixedly connected to the mounting plate 4311 via the same bolt.

[0105] 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.

[0106] 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 collinear, the first box door 111 and the second box door 112 can rotate around the same rotation axis, so that the connection structure between the box door 110 and the box body 500 is more reasonable and more convenient for installation.

[0107] Further, in one embodiment, as Figure 7 shown, 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 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 fourth hinge shaft 422 is arranged on the top surface of the extension plate 4212 and extends upward. The fourth traction component 310 is arranged on one of the third hinge plate 421 and the fourth hinge shaft 422.

[0108] Exemplarily, the third hinge plate 421 and the fourth hinge shaft 422 can also be made of metal or non-metal materials with a certain structural strength. The third hinge plate 421 includes a support plate 4211 and an extension plate 4212 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 the like. The support plate 4211 is provided with a plurality of mounting holes. The fourth hinge shaft 422 is fixedly arranged on the extension plate 4212 by welding or threaded connection or the like.

[0109] During actual installation, a plurality of threaded holes can be set in advance at a position near the bottom on the front surface of the box body 500. Then, 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 by means of bolts. The extension plate 4212 is connected to the other side in the thickness direction of the support plate 4211 and extends towards the direction where the second box door 112 is located. Moreover, the fourth hinge shaft 422 extends upward along the height direction of the box body 500.

[0110] Based on this, when installing the installation 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.

[0111] In addition, a sliding door mechanism 300 is connected to the bottom of the second box door 112. The traction component 310 in the sliding door mechanism 300 can be set on the third hinge plate 421 or on the fourth hinge shaft 422.

[0112] For example, as Figure 10 shown, during actual installation, the support plate 4211 is fixed at a position on the front of the box body 500 near the bottom. The second box door 112 is rotatably connected to the fourth hinge shaft 422, and part of the structure in the traction component 310 can be connected to the support plate 4211 by bolts.

[0113] 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 third hinge 420 is provided at the bottom of the box body 500, and a second hinge 430 is provided in the middle of the box body 500 and approximately at a position between the two storage spaces. 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.

[0114] 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.

[0115] 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.

[0116] Furthermore, in an embodiment, as Figure 11As 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 top of the box door 110 is rotatably provided on the box body 500 through the hinge shaft; the first end of the traction assembly 310 is configured to be rotatably provided on the hinge plate, the second end of the traction assembly 310 is configured to be rotatably provided on the box door 110, and the first end of the traction assembly 310 is arranged in a dislocation manner with respect to the hinge shaft; during the opening or closing process of the box door 110, the second end of the traction assembly 310 rotates relative to the box door 110, thereby driving the sliding door assembly 320 to drive the cabinet door 200 to move along the width direction of the box door 110.

[0117] 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 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 advance on the box door 110. 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.

[0118] In this embodiment, the first end of the traction assembly 310 is rotatably provided on the hinge 400. When the box door 110 rotates relative to the box body 500 around the hinge shaft, the second end of the traction assembly 310 rotates in a circular motion with the hinge shaft as the center. Since the first end of the traction assembly 310 is arranged in a dislocation manner with respect to the hinge shaft, the distance between the first end and the second end of the traction assembly 310 will change, and the position of the second end of the traction assembly 310 on the box door 110 is fixedly arranged, thereby driving the second end of the traction assembly 310 to rotate relative to the box door 110.

[0119] Optionally, the traction assembly 310 can be a crank mechanism or a gear assembly.

[0120] The sliding door assembly 320 is used to convert the rotational motion of the traction assembly 310 into a linear motion and drive the cabinet door 200 to move linearly relative to the box door 110.

[0121] Optionally, the sliding door assembly 320 can be a crank-slider mechanism or a lead screw mechanism.

[0122] In practical applications, during the opening process of the box door 110, the box door 110 drives the second end of the traction component 310 to rotate relative to the hinge axis. Based on the misaligned arrangement of the first end of the traction component 310 and the hinge axis, the distance between the first end and the second end of the traction component 310 increases, driving the second end of the traction component 310 to rotate clockwise relative to the box door 110. Furthermore, it controls the sliding door component 320 to drive the cabinet door 200 to move away from the hinge 400 along the width direction of the box door 110, thus avoiding interference between the cabinet door 200 and the side cabinet body. During the closing process of the box door 110, the box door 110 drives the second end of the traction component 310 to rotate relative to the hinge axis. Based on the misaligned arrangement of the first end of the traction component 310 and the hinge axis, the distance between the first end and the second end of the traction component 310 decreases, driving the second end of the traction component 310 to rotate counterclockwise relative to the box door 110. Furthermore, it controls the sliding door component 320 to drive the cabinet door 200 to move towards the hinge 400 along the width direction of the box door 110, so as to ensure that the cabinet door 200 can avoid the side cabinet body when the box door 110 is closed and reset the cabinet door 200.

[0123] For the sliding door mechanism 300 shown in this embodiment, by rotatably arranging the first end of the traction component 310 on the box body 500, rotatably arranging the second end of the traction component 310 on the box door 110, misaligning the first end of the traction component 310 with the hinge axis between the box body 500 and the box door 110, and arranging the sliding door component 320 between the second end of the traction component 310 and the cabinet door 200. When the box door 110 is opened, the box door 110 drives the second end of the traction component 310 to rotate relative to the box door 110, controlling the sliding door component 320 to drive the cabinet door 200 to move away from the hinge 400 along the width direction of the box door 110, avoiding interference between the cabinet door 200 and the side cabinet body. When the box door 110 is closed, it drives the second end of the traction component 310 to rotate relative to the box door 110, controlling the sliding door component 320 to drive the cabinet door 200 to move towards the hinge 400 along the width direction of the box door 110, so that the cabinet door 200 can return to its original position, effectively preventing interference between the cabinet door 200 and the side cabinet body.

[0124] In some embodiments, such as Figure 11 and Figure 12 shown, the traction component 310 includes: a first connecting rod 331 and a second connecting rod 332.

[0125] The first end of the first connecting rod 331 is rotatably arranged on the box body 500 and is misaligned with the hinge axis.

[0126] The first end of the second connecting rod 332 is rotatably connected to the second end of the first connecting rod 331; the second end of the second connecting rod 332 is rotatably arranged on the box door 110 and is connected to the sliding door component 320.

[0127] It is understandable that the first link 331 and the second link 332 are connected by a rotating shaft, and the first link 331 and the second link 332 can rotate relative to each other. The first link 331 can rotate relative to the cabinet body 500, and the second link 332 can rotate relative to the cabinet door 110. For example, the second end of the second link 332 can be rotatably arranged on the cabinet door via a rotating shaft.

[0128] When the cabinet door 110 rotates in a circular motion with the hinge axis of the hinge 400 as the center, since the first end of the first link 331 is arranged offset from the hinge axis, the distance between the second end of the second link 332 and the first end of the first link 331 changes, while the position of the second end of the second link 332 relative to the rotation axis of the cabinet door 110 remains unchanged. At this time, the second end of the second link 332 rotates on the cabinet door 110 around the rotation axis, and thereby drives the sliding door assembly 320 to drive the cabinet door 200 to move along the width direction of the cabinet door 110.

[0129] In practical applications, during the opening process of the cabinet door 110, the cabinet door 110 drives the second end of the second link 332 to rotate relative to the hinge axis. Based on the offset arrangement of the first end of the first link 331 from the hinge axis, the distance between the first end of the first link 331 and the second end of the second link 332 increases, driving the second end of the second link 332 to rotate relative to the cabinet door 110 in a first direction, such as clockwise, and then controlling the sliding door assembly 320 to drive the cabinet door 200 to move along the width direction of the cabinet door 110 away from the hinge 400, so as to avoid interference between the cabinet door 200 and the side cabinet body; during the closing process of the cabinet door 110, the cabinet door 110 drives the second end of the second link 332 to rotate relative to the hinge axis. Based on the offset arrangement of the first end of the first link 331 from the hinge axis, the distance between the first end of the first link 331 and the second end of the second link 332 decreases, driving the second end of the second link 332 to rotate relative to the cabinet door 110 in a second direction opposite to the first direction, such as counterclockwise, and then controlling the sliding door assembly 320 to drive the cabinet door 200 to move along the width direction of the cabinet door 110 towards the hinge 400, so that the cabinet door 200 can avoid the side cabinet body when the cabinet door 110 is closed and ensure the effective reset of the cabinet door 200.

[0130] In this embodiment, by providing the first link 331 and the second link 332 in the traction assembly 310, a compact design in a smaller space can be achieved, and the structure is simple and easy to repair.

[0131] In some embodiments, as Figure 11 and Figure 12 shown, the sliding door assembly 320 includes: a gear 341 and a rack 342.

[0132] The gear 341 is connected to the second end of the traction assembly 310 and can rotate driven by the traction assembly 310.

[0133] The rack 342 is meshed with the gear 341. The rack 342 extends in the width direction and is configured to be connected to the cabinet door 200.

[0134] Wherein, 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.

[0135] Wherein, 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 box door 110 and is meshed and connected with the gear through the teeth arranged at the second end of the second connecting rod. The gear is rotatably arranged on the box door 110.

[0136] Alternatively, the traction assembly includes an arc rack and a gear transmission assembly which are meshed and connected. The gear transmission assembly includes a plurality of meshed gears. The arc rack is arranged on the hinge plate of the hinge 400. The gear transmission assembly is rotatably arranged on the box door 110. Thus, in the case where the gear transmission assembly moves relative to the arc rack, the gear 341 is driven to rotate by the gear transmission assembly.

[0137] In an alternative embodiment, the gear 341 is arranged at the second end of the traction assembly 310, and the gear 341 is meshed with the rack 342. For example, the gear 341 can be fixedly arranged at the second end of the second connecting rod 332, and the gear 341 can rotate following the second end of the second connecting rod 332.

[0138] When the cabinet door 110 is opened, the cabinet door 110 drives the second end of the traction assembly 310 to rotate relative to the hinge axis. The distance between the first end and the second end of the traction assembly 310 increases, driving the second end of the traction assembly 310 to rotate relative to the cabinet door 110 in the first direction, for example, clockwise rotation. Based on the unchanged installation position of the gear 341 on the cabinet door 110, the gear 341 is further driven to rotate in the first direction. The rotation of the gear 341 drives the rack 342 to move away from the hinge 400 in the width direction of the cabinet door 110. The rack 342 drives the cabinet door 110 to move away from the hinge 400, so as to avoid interference between the cabinet door 200 and the side cabinet body. During the closing process of the cabinet door 110, the cabinet door 110 drives the second end of the traction assembly 310 to rotate relative to the hinge axis. The distance between the first end and the second end of the traction assembly 310 decreases, driving the second end of the traction assembly 310 to rotate relative to the cabinet door 110 in the second direction opposite to the first direction, for example, counterclockwise rotation. Based on the unchanged installation position of the gear 341 on the cabinet door 110, the gear 341 is further driven to rotate in the second direction. The rotation of the gear 341 drives the rack 342 to move towards the hinge 400 in the width direction of the cabinet door 110. The rack 342 drives the cabinet door 110 to move towards the hinge 400, so as to ensure that the cabinet door 200 can avoid the side cabinet body when the cabinet door 110 is closed and effectively reset the cabinet door 200.

[0139] In this embodiment, by setting the sliding door assembly 320 as the gear 341 and the rack 342, the structure is simple, easy to install and maintain, and can improve the transmission efficiency.

[0140] In another embodiment, 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, and the second rotating shaft fixing seat 313 is connected to the hinge 400 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 cabinet 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 cabinet door 110.

[0141] 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.

[0142] In actual use, when the box door 110 rotates between 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 relative to the box door 110 in the width direction of the box door 110.

[0143] Further, in yet another specific implementation, 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 Figures 13 to 15 shown, the sliding door assembly 320 includes: a base 321, a first slider 322, a second slider 323, and a connecting member 324.

[0144] Specifically, a first guide rail 3211 is formed on one side of the base 321, and a second guide rail 3212 is formed on the other side; the first slider 322 is slidably disposed on the first guide rail 3211, and the first rotating shaft fixing seat 312 is connected to the first slider 322; the second slider 323 is slidably disposed on the second guide rail 3212 and is connected to the cabinet door 200; both ends of the connecting member 324 are respectively connected to the first slider 322 and the second slider 323.

[0145] 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.

[0146] Optionally, 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 disposed on both sides in 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 disposed on the first guide rail 3211, and the second slider 323 is slidably disposed on 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.

[0147] Correspondingly, the traction rod 311 can be configured as an arc-shaped 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.

[0148] As one implementation, as Figure 14 and Figure 15As 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.

[0149] Similarly, as Figure 13 and Figure 15 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.

[0150] The first slider 322 and the second slider 323 are connected to each other by a connecting member 324. During the movement of the first slider 322, it can drive the second slider 323 to move in the opposite direction by means of the connecting member 324.

[0151] 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.

[0152] Next, 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.

[0153] 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 a clamping structure or the like.

[0154] During actual use, as Figure 13 and Figure 14As shown, when the box 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 box door 110, 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. Among them, 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.

[0155] Correspondingly, when the box 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 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.

[0156] Among them, the first guide rail and the second guide rail are used as a kind of track, and the first slider 322 and the second slider 323 are sliding parts that are adapted to the corresponding guide rails and can slide along the corresponding guide rails. In addition, the sliding fit between the first slider 322 and the first guide rail should at least include the case where there are ball bearings 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 ball bearings arranged between the second slider 323 and the second guide rail.

[0157] Further, in one 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 13 to 15 shown, the connecting piece 324 includes: a first connecting piece 3241 and a second connecting piece 3242.

[0158] Among them, 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.

[0159] 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 its two ends 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.

[0160] 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.

[0161] 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.

[0162] 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 15 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.

[0163] Specifically, as Figure 15 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 can be arranged on the outer circumference 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.

[0164] 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. In order to facilitate receiving the second connecting member 3242, a receiving groove extending along the circumferential direction can also be provided 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.

[0165] Thus, in the above setting manner, 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 and cause wear and tear, and an effective protection effect can be achieved on the first connecting member 3241 and the second connecting member 3242.

[0166] In addition, as described above, a refrigeration device is also 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.

[0167] Finally, it should be noted that: the parallelism and perpendicularity referred to in the embodiments of the present invention should not be strictly limited in the geometric sense, and at least manufacturing and installation errors should be considered. For example, errors of plus or minus 10° should be within the scope protected by the embodiments of the present invention.
