[0059] 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 box body 500, and the box body 500 forms a storage space, and the storage space can be used to place items such as vegetables and fruits that need to be refrigerated or frozen. Optionally, a refrigeration device and the like are also provided in the box body 500 of the refrigeration equipment, and the refrigeration device can perform refrigeration treatment on the storage space.

[0060] 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 along the height direction of the box body 500. Exemplarily, Figure 3 The door device shown in includes two door components 100.

[0061] Furthermore, each door component 100 includes a box door 110, a cabinet door 200 and at least one sliding door mechanism 300.

[0062] Among them, there are two door components among the plurality of door components 100. For example, the two door components are respectively a first door component and a second door component. 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 box body 500 through hinges 400.

[0063] The first door component is correspondingly connected with two hinges 400, and the box door 110 in the first door component is rotatably connected to the box body 500 through the hinge axes of the two hinges 400. The hinge axis of one hinge 400 is located at the top of the box door 110 in the first door component, and the hinge axis of the other hinge 400 is located at the bottom of the box door 110 in the first door component. At the same time, traction components 310 are respectively arranged on the two hinges. The second door component is correspondingly connected with one hinge 400, and the box door 110 in the second door component is rotatably connected to the box body 500 through the hinge axis of the hinge 400, and the hinge axis of the hinge 400 is located at the bottom of the box door 110 in the second door component. At the same time, a traction component 310 is also arranged on the hinge.

[0064] In this embodiment, 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 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 box 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.

[0065] For the convenience of expressing the positional relationship between each component, in this embodiment, as Figure 3As shown, the box body 500 is generally constructed 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.

[0066] 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. One side of the box door 110 in the width direction of the box body 500 is connected with a hinge 400. 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.

[0067] 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.

[0068] The box door 110 is generally constructed 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. One side of the box door 110 in the width direction can be rotatably connected to the box body 500 via the hinge 400. For example, as Figure 3 shown, the box door 110 is connected with a hinge 400 on the right side of the box body 500 in the width direction. The box door 110 can be rotatably connected to the box body 500 via the hinge 400.

[0069] 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.

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

[0071] In an actual use scenario, the outer wall surface of the cabinet door 200 can be selected to have the same material and shape as the outer wall surface of the cabinet, and the same decoration can be attached, so that the refrigeration device can have sufficient coordination with the cabinet and ensure aesthetics.

[0072] After the door body device in the present embodiment is installed on the cabinet body 500 of the refrigeration device, a plurality of 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.

[0073] 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 avoids the side walls of the first cabinet body 510 and the second cabinet body 520;

[0074] Alternatively, the door body device and the cabinet body 500 are configured to be arranged in the cabinet; during the process of opening or closing the 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 avoids the side walls of the cabinet.

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

[0076] In practice, as Figure 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, a plurality of 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.

[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, so that the cabinet door 200 can avoid the side walls of the first cabinet body 510 and the second cabinet body 520.

[0078] Alternatively, after the refrigeration device is placed in the cabinet body, the cabinet door 200 can be arranged outside 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 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 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.

[0079] 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 wall of the cabinet body.

[0080] Furthermore, in the sliding door mechanism 300 of the present embodiment, as Figure 11 and Figure 13 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.

[0081] 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.

[0082] Thus, when the door body device in the present embodiment is installed on the cabinet body 500 of the refrigeration device, multiple 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 the cabinet in an embedded manner, without affecting the coordination, aesthetics and the user experience, the interference between the cabinet door 200 and the cabinet can be avoided during the opening of the cabinet door 110.

[0083] Furthermore, in one embodiment, asFigure 3 As 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 500, and the second hinge 430 and the third hinge 420 are 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, the bottom of the first cabinet door 111 is rotatably connected to the cabinet 500 through the second hinge 430, and the bottom of the second cabinet door 112 is rotatably connected to the cabinet 500 through the third hinge 420.

[0084] Exemplarily, the number of the 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 for fixedly setting on the top wall of the cabinet 500, the second hinge 430 and the third hinge 420 are used for fixedly setting on the front surface of the cabinet 500, and both the first hinge 410 and the second hinge 430 can be used for connecting the cabinet door 110.

[0085] 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.

[0086] The top of the first cabinet door 111 can be rotatably connected to the cabinet 500 through the first hinge 410, the bottom of the first cabinet door 111 can be rotatably connected to the cabinet 500 through the second hinge 430, and the bottom of the second cabinet door 112 can be rotatably connected to the cabinet 500 through the third hinge 420.

[0087] In practical applications, according to different refrigeration requirements, different refrigeration equipment cabinets 500 are 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 used for refrigeration, and some storage spaces are used for freezing. Correspondingly, in order to be able to close these storage spaces targeted, the number of cabinet doors 110 can be multiple, and each cabinet door 110 corresponds to at least one of the storage spaces.

[0088] 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.

[0089] 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 used for refrigeration, and the third space is used 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.

[0090] 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.

[0091] 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 rest protrudes from the top wall towards the cabinet door 110. 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 first traction assembly 310 is arranged on one of the first hinge plate 411 and the first hinge shaft 412.

[0092] Exemplarily, the first hinge plate 411 and the first hinge shaft 412 can be made of a metal or non-metal material with a certain structural strength. The first hinge plate 411 includes a first fitting part and a first protruding part that are connected to each other. The first fitting part is provided with a plurality of mounting holes, and the first hinge shaft 412 is fixedly arranged on the first protruding part by means of welding or threaded connection.

[0093] During actual installation, a plurality of threaded holes can be provided in advance on the top wall of the cabinet 500. Then, let the first fitting part of the first hinge plate 411 fit to the top wall of the cabinet 500, and at the same time make the mounting holes on the first fitting part correspond to the positions of the threaded holes. Then, fix the first fitting part 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.

[0094] Based on this, when installing the box door 110, a hinge hole can be set at the top of the first box door 111 in advance, and then the first hinge shaft 412 is inserted into the hinge hole, thereby realizing the installation of the first box door 111.

[0095] 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 arranged on the first hinge plate 411 or on the first hinge shaft 412 .

[0096] For example, Figure 5 As shown, in one embodiment, a vertical plate 413 is disposed on the first hinge plate 411 , and the vertical plate 413 extends downward along the thickness direction of the first hinge plate 411 , and a mounting hole is disposed on the vertical plate 413 .

[0097] like Figure 8 As 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 means of bolts.

[0098] Further, in one embodiment, if Figure 6 As shown, the second hinge 430 includes a second hinge plate 431, a second hinge axis 432 and a third hinge axis 433, the second hinge plate 431 includes a mounting plate 4311 and a connecting plate 4312, the mounting plate 4311 is installed on the front side of the box body 500, the connecting plate 4312 is connected to the side of the mounting plate 4311 away from the front side of the box body 500, the connecting plate 4312 is arranged 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 axis 432 is arranged on the first side, the bottom of the first box door 111 is hinged to the second hinge axis 432, the third hinge axis 433 is arranged on the second side, the top of the second box door 112 is hinged to the third hinge axis 433, and the second traction assembly 310 is arranged on one of the second hinge plate 431 and the second hinge axis 432.

[0099] Exemplarily, the second hinge plate 431, the second hinge shaft 432 and the third hinge shaft 433 can be made of metal material or non-metal material with certain structural strength, and 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. In actual production and manufacturing, the mounting plate 4311 and the connecting plate 4312 can be integrally formed on the same plate, and then the connecting plate 4312 can be bent relative to the mounting plate 4311 by stamping and folding.

[0100] On both sides of the connecting plate 4312 in the thickness direction are a first side and a second side respectively. A second hinge shaft 432 is fixedly connected to the first side, and a third hinge shaft 433 is fixedly connected to the second side.

[0101] 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.

[0102] 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, make the mounting holes on the mounting plate 4311 of the second hinge plate 431 correspond to the positions of the threaded holes, and then fix the mounting plate 4311 to the front surface of the box body 500 with 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 upwards along the height direction of the box body 500, and the third hinge shaft 433 extends downwards along the height direction of the box body 500.

[0103] 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 achieved.

[0104] In addition, a sliding door mechanism 300 is connected to the bottom of the first box door 111. The traction component 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.

[0105] In one embodiment, as Figure 9 shown, the first box door 111 is provided with a sliding door mechanism 300. The traction component 310 in the sliding door mechanism 300 can be fixedly connected to the mounting plate 4311 via bolts.

[0106] Further, in one embodiment, the central axes of the second hinge shaft 432 and the third hinge shaft 433 are arranged to coincide.

[0107] It can be understood that by arranging the central axes of the second hinge shaft 432 and the third hinge shaft 433 to be collinear, the first door 111 and the second door 112 can be rotated around the same rotation axis, so that the connection structure between the door 110 and the box body 500 is more reasonable and more convenient for installation.

[0108] 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 the 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 bottom of the second door 112 is hinged to the fourth hinge shaft 422, and the third traction assembly 310 is arranged on one of the third hinge plate 421 and the fourth hinge shaft 422.

[0109] Exemplarily, the third hinge plate 421 and the fourth hinge shaft 422 can also be made of a metal or non-metal material 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 substantially perpendicular to the support plate 4211, and the two can be integrally formed by stamping or the like. The support plate 4211 is provided with a plurality of mounting holes, and the fourth hinge shaft 422 is fixedly arranged on the extension plate 4212 by welding or threaded connection or the like.

[0110] During actual installation, a plurality of threaded holes can be provided in advance at a position near the bottom on the front surface of the box body 500. Then, one side of the support plate 4211 in the thickness direction 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 of the support plate 4211 in the thickness direction and extends toward the direction where the second door 112 is located. Moreover, the fourth hinge shaft 422 extends upward along the height direction of the box body 500.

[0111] Based on this, when installing the door 110, a hinge hole can be provided in advance at the bottom of the second door 112. Then, the fourth hinge shaft 422 is inserted into the hinge hole, and thus, the installation of the second door 112 can be realized.

[0112] 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 arranged on the third hinge plate 421 or on the fourth hinge shaft 422.

[0113] 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 and near the bottom. The second box door 112 is rotatably connected to the fourth hinge shaft 422. Some structures in the traction component 310 can be connected to the support plate 4211 by means of bolts.

[0114] In a specific embodiment, as Figure 3 shown, two storage spaces are arranged at intervals along the height direction of the box body 500. A first hinge 410 is arranged at the top of the box body 500. A second hinge 430 is arranged in the middle of the box body 500 and approximately at a position between the two storage spaces. A third hinge 420 is arranged at the bottom of the box body 500. The door device includes two door components 100. The two door components 100 respectively include a first box door 111 and a second box door 112. The first box door 111 and the second box door 112 are arranged at intervals along the height direction of the box body 500. The first box door 111 and the second box door 112 respectively correspond to the two storage spaces of the box body 500.

[0115] 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.

[0116] 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.

[0117] Furthermore, in an embodiment, as Figure 11As shown, 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 disposed on the hinge plate. The hinge plate is disposed on the cabinet 500, and the bottom of the cabinet door 110 is rotatably disposed on the cabinet 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 cabinet 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 cabinet door 110.

[0118] Exemplarily, the hinge 400 may include a hinge plate and a hinge shaft, and the hinge shaft is fixedly disposed on the hinge plate by means such as welding. During actual installation, the hinge plate can be fixedly disposed on the cabinet 500 by means of structures such as bolts. Threaded holes can be provided in the cabinet door 110 in advance. After the hinge plate is fixed to the cabinet 500, the hinge shaft can be inserted into the hinge hole of the cabinet door 110, thereby realizing the rotational connection of the cabinet door 110 relative to the cabinet 500.

[0119] In the traction assembly 310, the first rotating shaft fixing seat 312 is disposed on the sliding door assembly 320, the second rotating shaft fixing seat 313 is disposed 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.

[0120] During actual use, when the cabinet door 110 rotates relative to the cabinet 500 between the positions of opening or closing the storage space, the traction assembly 310 can pull the sliding door assembly 320 to act, so that the sliding door assembly 320 drives the cabinet door 200 to move relative to the cabinet door 110 in the width direction of the cabinet door 110.

[0121] Further, in one embodiment, to enable the sliding door assembly 320 to effectively drive the cabinet door 200 to move relative to the cabinet door 110 under the drive of the traction assembly 310, as Figure 11 and Figure 12 shown, the sliding door assembly includes: a base 321, rolling elements, a first slider 322, a second slider 323, and a connecting member 324.

[0122] Wherein, a first guide rail 3211 is formed on one side of the base 321, and a second guide rail 3212 is formed on the other side; the first slider 322 is sleeved on the first guide rail 3211, and the first slider 322 is slidably arranged on the first guide rail 3211 through rolling elements, the first rotating shaft fixing seat 312 is connected to the first slider 322, the second slider 323 is sleeved on the second guide rail 3212, the second slider 323 is slidably arranged on the second guide rail 3212 through rolling elements, and is connected to the cabinet door 200; a connecting member 324, with two ends respectively connected to the first slider 322 and the second slider 323; during the opening or closing process of the box door 110, the traction rod 311 drives the first slider 322 to move on the first guide rail 3211, and the first slider 322 drives the second slider 323 to move in the opposite direction on the second guide rail 3212 through the connecting member 324.

[0123] Exemplarily, in this embodiment, the sliding door mechanism 300 can be arranged on the box door 110, one of the first slider 322 and the second slider 323 is in transmission connection with the box body 500, and the other is slidably connected to the cabinet door 200 arranged on the outer side of the box door 110. When the box door 110 rotates, the two sliders can slide relative to each other to drive the cabinet door 200 to slide relative to the box door 110, so that the cabinet door 200 can avoid obstacles on both sides during the rotation and opening / closing process of the box door 110.

[0124] Wherein, by respectively arranging rolling elements between the first slider 322 and the first guide rail 3211, and between the second slider 323 and the second guide rail 3212, the sliding friction between the slider and the guide rail is converted into rolling friction, making the sliding of the first slider 322 and the second slider 323 smoother, and thus making the sliding of the door panel smoother.

[0125] Specifically, taking the first slider 322 being connected to the box body 500 and the second slider 323 being connected to the cabinet door 200 as an example, the base 321 can be arranged on the box door 110. The connecting member 324 can be a connecting component such as a traction rope or a transmission belt. The two ends of the connecting member 324 are respectively connected to the first slider 322 and the second slider 323, enabling the first slider 322 to drive the second slider 323 to move synchronously, and further driving the cabinet door 200 to slide relative to the box door 110.

[0126] By reasonably setting the extending direction of the connecting member 324, the first slider 322 and the second slider 323 move in opposite directions during movement, so as to drive the cabinet door 200 to avoid obstacles.

[0127] It can be understood that the first slider 322 can also be connected to the cabinet door 200. Correspondingly, the second slider 323 is connected to the box body 500, and its working process is the same as that of the above embodiment, and will not be elaborated here.

[0128] To ensure that the first slider 322 can drive the second slider 323 to move in opposite directions on the base 321, as Figure 11 shown, the connecting member 324 includes: a first connecting member 3241 and a second connecting member 3242. Both the first connecting member 3241 and the second connecting member 3242 are flexible ropes. The first connecting member 3241 bypasses the first end in the length direction of the base 321, and its two ends are respectively connected to one end of the first slider 322 and the second slider 323; the second connecting member 3242 bypasses the second end in the length direction of the base 321, and its two ends are respectively connected to the other end of the first slider 322 and the second slider 323.

[0129] In this embodiment, by allowing the first connecting member 3241 to bypass the first end of the base 321 and then be connected to the first slider 322 and the second slider 323 respectively, when the first slider 322 slides towards the second end of the base 321, the first slider 322 can drive the second slider 323 to slide towards the first end of the base 321 through the first connecting member 3241; at the same time, by allowing the second connecting member 3242 to bypass the second end of the base 321 and then be connected to the first slider 322 and the second slider 323 respectively, when the first slider 322 slides towards the first end of the base 321, the first slider 322 can drive the second slider 323 towards the second end of the base 321 through the second connecting member 3242, so as to achieve that when the first slider 322 slides towards both ends of the base 321 respectively, it can drive the second slider 323 to slide in the opposite direction to the first slider 322. Finally, when the door 110 is opened and closed and rotates, the cabinet door 200 can slide relative to the door 110 to avoid interference with obstacles and affect the opening and closing of the door 110.

[0130] 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 this through hole and connected to the hinge plate, thereby fixing the second rotating shaft fixing seat 313 on the hinge plate.

[0131] Then, the base 321 can be fixed on the door 110 by means of structures such as bolts. Exemplarily, joint plates 325 are respectively provided on both sides in the length direction of the base 321, and through holes are respectively provided on the two joint plates 325. During installation, an external bolt can be passed through the through holes on the two joint plates 325 and connected to the door 110, thereby fixing the base 321 on the door 110.

[0132] 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.

[0133] During actual use, asFigure 11 As 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 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 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 B direction. Wherein, 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 box door 110.

[0134] 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 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 box door 110 along the direction opposite to the B direction.

[0135] Furthermore, in one embodiment, as Figure 12 shown, a first rolling gap is formed between the first slider 322 and the first guide rail 3211, and a second rolling gap is formed between the second slider 323 and the second guide rail 3212; the rolling elements include a first ball 331 and a second ball 332. The first ball 331 is rotatably arranged in the first rolling gap, and the second ball 332 is rotatably arranged in the second rolling gap.

[0136] In this embodiment, by respectively forming the first rolling gap between the first slider 322 and the first guide rail 3211 and the second rolling gap between the second slider 323 and the second guide rail 3212, it is possible to avoid direct contact between the first slider 322 and the first guide rail 3211, and between the second slider 323 and the second guide rail 3212. And rotatable first balls 331 and second balls 332 are respectively arranged in the first rolling gap and the second rolling gap, so that the first slider 322 can slide along the first guide rail 3211 through the rolling of the first ball 331, and the second slider 323 can slide along the second guide rail 3212 through the rolling of the second ball 332, with small friction and smoother sliding.

[0137] Exemplarily, as Figure 12As shown, multiple rows of first rolling gaps are formed between the first slider 322 and the first guide rail 3211, and multiple rows of second rolling gaps are formed between the second slider 323 and the second guide rail 3212; the rolling elements include multiple groups of first balls 331 and multiple groups of second balls 332, and each group of first balls 331 is respectively arranged in each row of first rolling gaps, and each group of second balls 332 is respectively arranged in each row of second rolling gaps.

[0138] In this embodiment, by setting multiple rows of first rolling gaps and arranging a group of first balls 331 in each row of first rolling gaps, multiple groups of first balls 331 can form multiple rolling support points between the first slider 322 and the first guide rail 3211, making the sliding of the first slider 322 relative to the first guide rail 3211 more stable and smooth. Similarly, by setting multiple rows of second rolling gaps and arranging a group of second balls 332 in each row of second rolling gaps, multiple groups of second balls 332 can also form multiple rolling support points between the second slider 323 and the second guide rail 3212, making the sliding of the second slider 323 relative to the first guide rail 3211 more stable and smooth.

[0139] Optionally, multiple first rolling gaps in each row can be arranged at intervals along the extending direction of the first guide rail 3211, and multiple second rolling gaps in each row can be arranged at intervals along the extending direction of the second guide rail 3212.

[0140] For example, as Figure 12 shown, both the first rolling gaps and the second rolling gaps are provided with four rows, and both the first balls 331 and the second balls 332 are provided with four groups.

[0141] In this embodiment, by setting four rows of first rolling gaps and second rolling gaps and correspondingly arranging four groups of first balls 331 and second balls 332, the first balls 331 and the second balls 332 are respectively arranged in four rows between the first slider 322 and the first guide rail 3211 and between the second slider 323 and the second guide rail 3212, making the sliding of the first slider 322 relative to the first guide rail 3211 and the sliding of the second slider 323 relative to the second guide rail 3212 more stable and smooth.

[0142] Optionally, the projections of the axes of the four rows of first rolling gaps on the cross-section of the first guide rail 3211 are arranged in a square, and are respectively located at the four vertices of the square, and the central axis of the first guide rail 3211 passes through the center of the square.

[0143] In a specific implementation, the first guide rail 3211 is provided with four first concave surfaces sequentially arranged along its circumferential direction. A first groove is formed on the first slider 322. Four rows of first rolling clearances are formed between the side walls of the first groove and the four first concave surfaces. The second guide rail 3212 is provided with four second concave surfaces sequentially arranged along its circumferential direction. A second groove is formed on the second slider 323. Four rows of second rolling clearances are formed between the side walls of the second groove and the four second concave surfaces.

[0144] Thus, by providing the first groove on the first slider 322 and the first concave surface on the first guide rail 3211, the first concave surface and the first groove are opposed to form the first rolling clearance. The first concave surface and the first groove respectively abut on both sides of the first ball 331. The first ball 331 can roll within the first rolling clearance to achieve the relative sliding between the first slider 322 and the first guide rail 3211. At the same time, the first concave surface can limit the first ball 331 in the circumferential direction of the first guide rail 3211 to prevent the first ball 331 from circumferentially shifting on the first guide rail 3211, making the sliding of the first slider 322 more stable and smooth. Similarly, the second groove on the second slider 323 and the second concave surface of the second guide rail 3212 are opposed to form the second rolling clearance. The second concave surface and the second groove respectively abut on both sides of the second ball 332, so that when the second ball 332 rolls to achieve the relative sliding between the second slider 323 and the second guide rail 3212, no circumferential shift will occur, making the sliding of the second slider 323 more stable and smooth.

[0145] Moreover, in order to prevent the balls from falling off from the rolling clearances, as Figure 12 shown, first limit members 341 are fixedly arranged at both ends of the first slider 322 in the length direction of the first rolling clearance. The first balls 331 accommodated in the first rolling clearance are restricted between the two first limit members 341. When the first slider 322 moves on the first guide rail 3211, under the restricting action of the first limit members 341, the first balls 331 will not fall off from the first rolling clearance.

[0146] Similarly, second limit members 342 are fixedly arranged at both ends of the second slider 323 in the length direction of the second rolling clearance. The second balls 332 accommodated in the second rolling clearance are restricted between the two second limit members 342. When the second slider 323 moves on the second guide rail 3212, under the restricting action of the second limit members 342, the second balls 332 will not fall off from the second rolling clearance.

[0147] Furthermore, in yet another specific implementation, as Figures 13 to 15As 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 in the width direction of the base 321. 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.

[0148] In some embodiments, the traction assembly includes: a first link and a second link. The first end of the first link is rotatably arranged on the hinge 400. For example, it is arranged on the hinge plate of the hinge 400.

[0149] Among them, the first end of the first link is rotatably arranged within the installation area. For example, the first end of the first link is installed within the installation area through a rotating shaft fixing seat. The first end of the second link is rotatably connected to the second end of the first link; the second end of the second link is rotatably arranged on the cabinet 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 link.

[0150] It can be understood that the first link and the second link are connected by a hinge, and the first link and the second link can rotate relative to each other. The first link can rotate relative to the box body 500, and the second link can rotate relative to the cabinet door 110.

[0151] When the second end of the second link makes a circular motion around the hinge axis with the cabinet door 110 as the center, 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 cabinet door 110 remains unchanged. As a result, the second end of the second link rotates around the cabinet door 110 and drives the second slider 323 to drive the cabinet door 200 to move along the width direction of the cabinet door 110.

[0152] In practical applications, during the opening process of the cabinet door 110, the cabinet 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 cabinet door 110. Furthermore, it controls the second slider 323 to drive the cabinet door 200 to move in the width direction of the cabinet door 110 away from the hinge 400, that is, move to the left relative to the cabinet door 110. In this way, it can avoid interference between the cabinet door 200 and the cabinet door 200 of 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 to rotate relative to the hinge axis. Based on the misaligned arrangement of the first end of the first link and the hinge axis, the distance between the first end of the first link and the second end of the second link decreases, driving the second end of the second link to rotate counterclockwise relative to the cabinet door 110. Furthermore, it controls the second slider 323 to drive the cabinet door 200 to move in the width direction of the cabinet door 110 towards the hinge 400, that is, move to the right relative to the cabinet door 110. In this way, it can ensure that the cabinet door 200 can avoid the cabinet door 200 of the side cabinet body when closing the cabinet door 110 and reset the cabinet door 200.

[0153] In an optional embodiment, the first rotating shaft fixing seat 312 is connected to the first slider 322, and the cabinet door 200 can be fixedly connected to the second slider 323. 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 members 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 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.

[0154] 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 the first rotating shaft, and the other end is rotatably connected to the second rotating shaft fixing seat 313 via the second rotating shaft.

[0155] As a way of implementation, as Figure 14 and Figure 15 shown, the first rotating shaft fixing seat 312 is provided with a first clamping portion. 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.

[0156] Similarly, as Figure 13 and Figure 15 shown, a second rotating shaft fixing seat 313 is provided with a second clamping portion. 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.

[0157] The first slider 322 and the second slider 323 are connected to each other through a connecting member 324. During the movement of the first slider 322, the second slider 323 can be driven to move in the opposite direction by means of the connecting member 324.

[0158] 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.

[0159] 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 arranged 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.

[0160] 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.

[0161] During actual use, as Figure 13 and Figure 14As shown, when the door 110 moves relative to the cabinet body 500 from the position closing the storage space towards the position opening the storage space, since the first rotating shaft fixing seat 312 is fixed to the door 110 following the hinge seat, during the rotation of the door 110, the first slider 322 will move along the C direction on the first guide rail 3211. Correspondingly, the first slider 322 will pull the second slider 323 to move along the D direction on the second guide rail 3212 through the connecting member 324. Since the base 321 is fixedly connected to the door 110 and the second slider 323 is fixedly connected to the cabinet door 200, at this time, the cabinet door 200 will move relative to the door 110 along the D direction. Wherein, the C direction is opposite to the D direction, and both the C direction and the D direction are parallel to the width direction of the door 110.

[0162] Correspondingly, when the door 110 moves relative to the cabinet body 500 from the position opening the storage space towards the position closing the storage space, during the rotation of the door 110, the first slider 322 will move along the direction opposite to the C direction on the first guide rail 3211. Correspondingly, the first slider 322 will pull the second slider 323 to move along the direction opposite to the D direction on the second guide rail 3212 through the connecting member 324. At this time, the cabinet door 200 will move relative to the door 110 along the direction opposite to the D direction.

[0163] 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 member 324 includes: a first connecting member 3241 and a second connecting member 3242.

[0164] Wherein, the first connecting member 3241 bypasses one end of the base 321, and both ends are respectively connected to one end of the first slider 322 and the second slider 323; the second connecting member 3242 bypasses the other end of the base 321, and both ends are respectively connected to the other end of the first slider 322 and the second slider 323.

[0165] 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 an end of the base 321. That is, in the length direction of the base 321, the first connecting member 3241 bypasses an end of the base 321, and both ends thereof extend towards the first slider 322 and the second slider 323 respectively, and are respectively connected to the first slider 322 and the second slider 323.

[0166] 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.

[0167] 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.

[0168] 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.

[0169] 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 periphery of the first roller 328 along its circumferential direction. Thus, when installing the first connecting member 3241, the first connecting member 3241 can be placed in the receiving grooves of the two first rollers 328. Thereafter, when the first slider 322 pulls the second slider 323 by means of the first connecting member 3241, the first connecting member 3241 can drive the two first rollers 328 to rotate.

[0170] Similarly, the number of the second rollers 329 is two. The two second rollers 329 are arranged at intervals in the width direction of the base 321. Moreover, the two second rollers 329 can be respectively rotatably arranged on the second receiving plate 327. In order to facilitate receiving the second connecting member 3242, a receiving groove can also be arranged on the outer periphery of the second roller 329 along its circumferential direction. Thus, when installing the second connecting member 3242, the second connecting member 3242 can be placed in the receiving grooves of the two second rollers 329. Thereafter, when the first slider 322 pulls the second slider 323 by means of the second connecting member 3242, the second connecting member 3242 can drive the two second rollers 329 to rotate.

[0171] Thus, in the above-described setting method, the first roller 328 can support and position the first connecting member 3241, and the second roller 329 can support and position the second connecting member 3242. By means of the first roller 328 and the second roller 329, it is possible to prevent the first connecting member 3241 and the second connecting member 3242 from contacting other components during movement and causing wear and tear, and an effective protective effect can be exerted on the first connecting member 3241 and the second connecting member 3242.

[0172] 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.

[0173] Finally, it should be noted that: the parallelism and perpendicularity referred to in the embodiments of the present invention should not be strictly limited in the geometric sense, and at least manufacturing and installation errors should be considered. For example, errors of plus or minus 10° should be within the scope protected by the embodiments of the present invention. In addition, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
