The door device and the refrigeration device in this embodiment are further described below with reference to Figures 3 to 15.

[0066] As shown in FIG. 3 and FIG. 4 , the door device in this embodiment includes: a box door 110 , a cabinet door 200 and a sliding door mechanism 300 .

[0067] Among them, the box door 110 is rotatably connected to the box body 500 through a hinge 400, and is suitable for opening or closing the storage space of the box body 500; the cabinet door 200 is slidably arranged on the outside of the box door 110; the sliding door mechanism 300 includes a connected traction component 310 and a sliding door component 320, the traction component 310 is arranged on the hinge 400, and the sliding door component 320 is arranged on the box door 110 and connected to the cabinet door 200, and the traction component 310 is configured to drive the sliding door component 320 to move 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.

[0068] The thickness of the cabinet door 110 is 18-60 mm, and for example, the thickness of the cabinet door 110 is 18 mm, 25 mm, 50 mm, 60 mm, etc. The thickness of the cabinet door 200 is 12-26 mm, and for example, 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.

[0069] It is understood that the door device in this embodiment can be used in refrigeration equipment such as refrigerators, freezers, and ice makers, wherein the refrigeration equipment includes a housing 500, which forms a storage space. The storage space can be used to place items such as vegetables and fruits that need to be refrigerated or frozen. Optionally, the housing 500 of the refrigeration equipment is further provided with a refrigeration device, etc., which can cool the storage space.

[0070] In this embodiment, the door 110 in the door device is rotatably arranged on the box body 500 of the refrigeration equipment through the hinge 400. 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 to close 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 to open the storage space, the storage space is in an open state, and the user can take out the items in the storage space.

[0071] In order to facilitate the expression of the positional relationship between the various components, in this embodiment, as shown in Figure 3, the box body 500 is roughly constructed as a rectangular 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, wherein 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.

[0072] A storage space is provided inside the box body 500, and an opening is provided on the side of the box body 500 in the thickness direction, which is connected to 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 is extended along the width direction of the box body 500. The box door 110 is connected to a hinge 400 on one side of the width direction of the box body 500. The box door 110 can be rotatably connected to the box body 500 via the hinge 400, thereby ensuring that the box door 110 can open or close the storage space of the box body 500.

[0073] Moreover, the side of the box body 500 on which the box door 110 is installed is the front side, that is, the box door 110 is installed on the front side of the box body 500 .

[0074] The door 110 is generally constructed as a flat plate structure having a certain thickness. The door 110 has a height direction, a width direction, and a thickness direction that are perpendicular to each other. The height direction of the door 110 is parallel to the vertical direction, and the width direction and the length direction are located in a horizontal plane and are perpendicular to each other. One side of the door 110 in the width direction can be rotatably connected to the box body 500 via a hinge 400. For example, as shown in Figure 3, the door 110 is connected to the hinge 400 on the right side of the box body 500 in the width direction, and the door 110 can be rotatably connected to the box body 500 via the hinge 400.

[0075] Moreover, when the door 110 is in a position to close the storage space of the box body 500 , the width direction of the door 110 is parallel to the width direction of the box body 500 , and the thickness direction of the door 110 is parallel to the thickness direction of the box body 500 .

[0076] Furthermore, the cabinet door 200 can be a decorative door panel. The cabinet door 200 is constructed as a flat plate structure with a certain thickness. The cabinet door 200 is connected to the outside of the cabinet door 110 away from the cabinet body 500. When the refrigeration equipment is placed together with the cabinet in an embedded manner or directly in the cabinet, when the cabinet 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 away from the cabinet door 110 can be flush with the outer wall surface of the cabinet.

[0077] In actual usage scenarios, the outer wall surface of the cabinet door 200 can be selected with the same material and shape as the outer wall surface of the cabinet, and can be attached with the same decoration, so that the refrigeration equipment can be sufficiently coordinated with the cabinet and can ensure aesthetics.

[0078] After the door device in this embodiment is installed on the cabinet 500 of the refrigeration equipment, when the cabinet door 110 rotates relative to the cabinet 500 to open or close the storage space of the cabinet 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. Therefore, when the refrigeration equipment is placed in an embedded manner in the cabinet, the cabinet door 200 can be prevented from interfering with the cabinet during the process of opening the cabinet door 110 while ensuring coordination and aesthetics and not affecting the user's experience.

[0079] In one embodiment, as shown in FIG4 , the door device and the cabinet 500 are configured to be disposed in an installation space formed between a first cabinet 510 and a 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 ;

[0080] 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.

[0081] It can be understood that the refrigeration device includes a door device and a box body 500.

[0082] In practice, as shown in FIG4 , when a refrigeration appliance having the door device and the cabinet 500 is placed between adjacent first and second cabinets 510, 520, a cabinet door 200 may be provided on the outer side of the cabinet door 110 in the door device, and the cabinet door 200 may be movable 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 facing away from the cabinet door 110 may be flush with the outer wall surfaces of the first and second cabinets 510, 520, and the outer wall surfaces of the first and second cabinets 510, 520 and the outer wall surface of the cabinet door 200 facing away from the cabinet door 110 are in the same direction in the thickness direction of the cabinet 500.

[0083] 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 .

[0084] Alternatively, after the refrigeration device is placed in the cabinet, a cabinet door 200 can be provided outside the cabinet door 110 of the door assembly, and the cabinet door 200 can 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 facing away from the cabinet door 110 can be flush with the outer wall surface of the cabinet, and the outer wall surface of the cabinet and the outer wall surface of the cabinet door 200 facing away from the cabinet door 110 are in the same direction in the thickness direction of the cabinet 500.

[0085] 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.

[0086] Furthermore, in the sliding door mechanism 300 of this embodiment, as shown in Figures 11 and 13 , the traction assembly 310 is disposed on the hinge 400, and the sliding door assembly 320 is disposed on the cabinet door 110. The sliding door assembly 320 is also 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 move, thereby driving the cabinet door 200 to move relative to the cabinet door 110.

[0087] For example, since the hinge 400 is fixedly connected to the box body 500, during the rotation of the box door 110 relative to the box 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 the pulling force.

[0088] Therefore, when the door device in this embodiment is installed on the cabinet body 500 of the refrigeration equipment, during the rotation of the cabinet door 110 relative to the cabinet body 500, the sliding door assembly 320 can allow the cabinet door 200 to move relative to the cabinet door 110 under the drive of the traction assembly 310, so that when the refrigeration equipment is placed in an embedded manner in the cabinet, while ensuring coordination and aesthetics and not affecting the user's experience, the cabinet door 200 can be prevented from interfering with the cabinet during the process of opening the cabinet door 110.

[0089] Furthermore, in one embodiment, there are multiple doors 110, each door 110 corresponds to at least one storage space; each door 110 is rotatably connected to the box body 500 through multiple hinges 400, and at least one of the multiple hinges 400 corresponding to each door 110 is provided with a traction assembly 310.

[0090] It can be understood that according to different refrigeration needs, the cabinet 500 of different refrigeration equipment can be provided with different numbers of storage spaces. These storage spaces are arranged at intervals along the height direction of the cabinet 500. Some storage spaces are used for refrigeration, and some storage spaces are used for freezing. Accordingly, in order to be able to close these storage spaces in a targeted manner, the number of cabinet doors 110 can be multiple, and each cabinet door 110 corresponds to at least one of the storage space positions.

[0091] For example, as shown in FIG3 , a cabinet 500 is provided with two storage spaces spaced apart in the vertical direction. The two storage spaces can be used for refrigeration and freezing, respectively. There are two cabinet doors 110 , namely a first cabinet door 111 and a second cabinet door 112 . The two cabinet doors 110 correspond to the positions of the two storage spaces. In this case, the two storage spaces can be opened or closed independently through the two cabinet doors 110 .

[0092] For another example, the cabinet 500 may be provided with three storage spaces spaced apart 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. There are two doors 110, namely, a first door 111 and a second door 112. The first door 111 corresponds to the positions of the first and second spaces, and the second door 112 corresponds to the position of the third space. In this case, the first door 111 can be used to open or close the first and second spaces simultaneously, and the second door 112 can be used to control the opening and closing state of the third space separately.

[0093] It can be understood that in this embodiment, each box door 110 can correspond to a separate storage space, in which case the box door 110 can independently control the opening and closing status of the storage space; or, depending on demand, each box door 110 can also correspond to multiple adjacent storage spaces, in which case the box door 110 can simultaneously control the opening and closing status of the multiple storage spaces.

[0094] Furthermore, in one embodiment, as shown in FIG. 3 , the hinge 400 includes a first hinge 410 and a second hinge 420 . The first hinge 410 is disposed on the top wall of the box 500 , and the second hinge 420 is disposed on the front surface of the box 500 .

[0095] Exemplarily, when there are multiple doors 110, the multiple doors 110 can be spaced apart along the height direction of the box body 500. At this time, the door 110 located at the top can be rotatably connected to the box body 500 via the first hinge 410, and the door 110 located at the bottom can be rotatably connected to the box body 500 via the second hinge 420.

[0096] Thus, by providing the first hinge 410 and the second hinge 420 , the top and bottom doors 110 can respectively open or close their corresponding storage spaces.

[0097] In a specific embodiment, as shown in Figure 3, the box door 110 includes a first box door 111 and a second box door 112. The first box door 111 and the second box door 112 are spaced apart along the height direction of the box body 500. At this time, the top of the first box door 111 can be rotatably connected to the box body 500 by means of a first hinge 410, and the bottom of the second box door 112 can be rotatably connected to the box body 500 by means of a second hinge 420.

[0098] Furthermore, in order to effectively realize the installation of the box door 110 , the hinge 400 may further include a third hinge 430 , wherein the third hinge 430 is arranged on the front side of the box body 500 , and the third hinge 430 is located between the first hinge 410 and the second hinge 420 .

[0099] Exemplarily, since multiple doors 110 are arranged at intervals along the height direction of the box body 500, a third hinge 430 can be provided between two adjacent doors 110, and at least one of the two adjacent doors 110 can be rotated to connect to the box body 500 with the help of the third hinge 430.

[0100] In practical applications, the number of third hinges 430 can be one or two. For example, when there is one third hinge 430, one of two adjacent doors 110 can be connected to the third hinge 430 and rotatably connected to the box body 500 via the third hinge 430. Alternatively, the two adjacent doors 110 can be simultaneously connected to the third hinge 430 and rotatably connected to the box body 500 via the third hinge 430.

[0101] For example, as shown in Figure 3, the box door 110 includes a first box door 111 and a second box door 112. At this time, the third hinge 430 can be set between the first box door 111 and the second box door 112, and the bottom of the first box door 111 and the top of the second box door 112 can be hinged to the third hinge 430 at the same time, so as to be rotatably connected to the box body 500.

[0102] Further, in one embodiment, as shown in Figure 5, the first hinge 410 includes a first hinge plate 411 and a first hinge shaft 412, part of the first hinge plate 411 covers the top wall of the box body 500 and the remaining part protrudes from the top wall toward the corresponding box door 110, the first hinge shaft 412 extends downward from the part of the protruding top wall of the first hinge plate 411, the top of the corresponding box door 110 is hinged to the first hinge shaft 412, and the traction assembly 310 is arranged on one of the first hinge plate 411 and the first hinge shaft 412.

[0103] Exemplarily, the first hinge plate 411 and the first hinge shaft 412 can be made of metal or non-metallic material with a certain structural strength. The first hinge plate 411 includes a first fitting portion and a first protrusion that are connected to each other. The first fitting portion is provided with a plurality of mounting holes. The first hinge shaft 412 is fixed on the first protrusion by welding or threaded connection.

[0104] During actual installation, multiple threaded holes can be set in advance on the top wall of the box body 500, and then the first fitting part of the first hinge plate 411 can be fitted to the top wall of the box body 500, and at the same time, the mounting hole on the first fitting part can correspond to the position of the threaded hole, and then the first fitting part can be fixed to the top wall of the box body 500 with the help of bolts. At this time, the first fitting part can cover and fit to the top wall of the box body 500, the first protrusion can protrude from the top wall toward the box door 110, and the first hinge shaft 412 can extend downward along the height direction of the box body 500.

[0105] Based on this, when installing the box door 110, a hinge hole can be set in advance at the top of the box door 110 corresponding to the first hinge 410, and then the first hinge shaft 412 is inserted into the hinge hole, thereby realizing the installation of the box door 110.

[0106] The box door 110 corresponding to the first hinge 410 is connected to the sliding door mechanism 300. For example, the top of the first box door 111 is connected to the sliding door mechanism 300. The traction component 310 in the sliding door mechanism 300 can be set on the first hinge plate 411 or on the first hinge shaft 412.

[0107] For example, as shown in FIG. 5 , 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 a mounting hole is provided on the vertical plate 413 .

[0108] As shown in FIG8 , during actual installation, the first hinge plate 411 is fixed to the top wall of the box body 500 , the first 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.

[0109] Further, in one embodiment, as shown in Figure 6, the second hinge 420 includes a second hinge plate 421 and a second hinge shaft 422, the second hinge plate 421 includes a support plate 4211 and an extension plate 4212, the support plate 4211 is installed on the front of the box body 500, and the extension plate 4212 is connected to the side of the support plate 4211 facing away from the front of the box body 500, the support plate 4211 and the extension plate 4212 are arranged at an angle, the second hinge shaft 422 is arranged on the top surface of the extension plate 4212 and extends upward, the bottom of the corresponding box door 110 is hinged to the second hinge shaft 422, and the traction assembly 310 is arranged on one of the second hinge plate 421 and the second hinge shaft 422.

[0110] Similarly, the second hinge plate 421 and the second hinge shaft 422 can also be made of metal or non-metallic materials with a certain structural strength. The second hinge plate 421 includes a support plate 4211 and an extension plate 4212 that are interconnected. The extension plate 4212 is roughly perpendicular to the support plate 4211. The two can be integrally formed by stamping or other methods. The support plate 4211 is provided with multiple mounting holes, and the second hinge shaft 422 is fixed on the extension plate 4212 by welding or threaded connection.

[0111] During actual installation, multiple threaded holes can be set in advance on the front of the box 500 and near the bottom, and then one side of the support plate 4211 in the thickness direction is fitted to the front of the box 500, and the mounting holes on the support plate 4211 correspond to the positions of the threaded holes, and then the support plate 4211 is fixed to the front of the box 500 with the help of bolts. The extension plate 4212 is connected to the other side of the support plate 4211 in the thickness direction and extends toward the direction of the box door 110. Moreover, the second hinge shaft 422 extends upward along the height direction of the box 500.

[0112] Based on this, when installing the box door 110, a hinge hole can be set in advance at the bottom of the box door 110 corresponding to the second hinge 420, and then the second hinge shaft 422 is inserted into the hinge hole, thereby realizing the installation of the box door 110.

[0113] The box door 110 corresponding to the second hinge 420 is connected to the sliding door mechanism 300. For example, the bottom of the second box door 112 is connected to the sliding door mechanism 300. The traction component 310 in the sliding door mechanism 300 can be set on the second hinge plate 421 or on the second hinge shaft 422.

[0114] As shown in Figure 9, during actual installation, the support plate 4211 is fixed on the front of the box body 500 and close to the bottom, the second box door 112 is rotatably connected to the second hinge shaft 422, and part of the structure in the traction assembly 310 can be connected to the support plate 4211 by means of bolts.

[0115] Further, in one embodiment, as shown in Figure 7, the third hinge 430 includes a third hinge plate 431, a third hinge axis 432 and a fourth hinge axis 433, the third hinge plate 431 includes a mounting plate 4311 and a connecting plate 4312, the mounting plate 4311 is installed on the front of the box body 500, the connecting plate 4312 is connected to the side of the mounting plate 4311 away from the front 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 relative to each other, the third hinge axis 432 is arranged on the first side, the corresponding bottom of the box door 110 is hinged to the third hinge axis 432, the fourth hinge axis 433 is arranged on the second side, the corresponding top of the box door 110 is hinged to the fourth hinge axis 433, and the third hinge 430 is provided with at least one traction assembly 310.

[0116] For example, the third hinge plate 431, the third hinge shaft 432, and the fourth hinge shaft 433 can be made of a metal or non-metal material with a certain structural strength. The third 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 is provided with a plurality of mounting holes. During actual production, the mounting plate 4311 and the connecting plate 4312 can be integrally formed from the same plate, and then the connecting plate 4312 can be bent relative to the mounting plate 4311 by stamping and folding.

[0117] Two sides of the connecting plate 4312 in the thickness direction are respectively a first side and a second side. The first side is fixedly connected to the third hinge shaft 432 , and the second side is fixedly connected to the fourth hinge shaft 433 .

[0118] During actual production, the third hinge axis 432 and the fourth hinge axis 433 can be respectively welded and fixedly connected to the connecting plate 4312. Alternatively, the third hinge axis 432 and the fourth hinge axis 433 can be constructed as a long, rod-shaped integral piece, with the connecting plate 4312 provided with a through hole extending through the thickness thereof, the integral piece being inserted into the through hole and fixed therein by welding or threading, with the third hinge axis 432 and the fourth hinge axis 433 being formed at both ends of the integral piece in the longitudinal direction on the connecting plate 4312.

[0119] During actual installation, as shown in Figure 10, multiple threaded holes can be set in advance on the front of the box body 500 according to the installation position of the box door 110. For example, as shown in Figure 3, multiple threaded holes are set on the front of the box body 500 corresponding to the gap position between the first box door 111 and the second box door 112. Then, the mounting holes on the mounting plate 4311 of the third hinge plate 431 are made to correspond to the positions of the threaded holes, and then the mounting plate 4311 is fixed to the front of the box body 500 with the help of bolts. At this time, the connecting plate 4312 extends toward the direction of the box door 110. At the same time, the third hinge shaft 432 extends upward along the height direction of the box body 500, and the fourth hinge shaft 433 extends downward along the height direction of the box body 500.

[0120] Based on this, when installing the box door 110, a hinge hole can be set in advance at the bottom of the box door 110 corresponding to the third hinge axis 432, and a hinge hole can be set in advance at the top of the box door 110 corresponding to the fourth hinge axis 433. Afterwards, the third hinge axis 432 and the fourth hinge axis 433 can be respectively inserted into the corresponding hinge holes of the box door 110, thereby realizing the installation of the box door 110.

[0121] In a specific embodiment, as shown in FIG3 , a box body 500 is provided with two storage spaces spaced apart along its height. A first hinge 410 is provided at the top of the box body 500, a second hinge 420 is provided at the bottom of the box body 500, and a third hinge 430 is provided in the middle of the box body 500, approximately between the two storage spaces. The door assembly includes two doors 110, namely a first door 111 and a second door 112. The first door 111 and the second door 112 are spaced apart along the height of the box body 500, and the first door 111 and the second door 112 respectively correspond to the two storage spaces of the box body 500.

[0122] During installation, the top of the first door 111 is hinged to the first hinge axis 412 of the first hinge 410, the bottom of the first door 111 is hinged to the third hinge axis 432 of the third hinge 430, the top of the second door 112 is hinged to the fourth hinge axis 433 of the third hinge 430, and the bottom of the second door 112 is hinged to the second hinge axis 422 of the second hinge 420.

[0123] Thus, through the above arrangement, the first door 111 and the second door 112 can be rotatably connected to the box body 500.

[0124] In addition, the third hinge 430 may be provided with at least one traction assembly 310 , for example, the third hinge 430 may be provided with only one traction assembly 310 , which may be connected to the third hinge plate 431 , the third hinge shaft 432 or the fourth hinge shaft 433 .

[0125] Furthermore, in this embodiment, the third hinge 430 is provided with a traction assembly 310 , and the traction assembly 310 is provided on one of the mounting plate 4311 , the connecting plate 4312 , the third hinge shaft 432 and the fourth hinge shaft 433 .

[0126] For example, the first door 111 or the second door 112 corresponding to the third hinge 430 is connected to the sliding door mechanism 300, and the traction assembly 310 in the sliding door mechanism 300 can be connected to the mounting plate 4311, the connecting plate 4312, the third hinge shaft 432, or the fourth hinge shaft 433. In this case, the third hinge 430 can be provided with only one traction assembly 310.

[0127] Furthermore, in one embodiment, the third hinge 430 is provided with two traction assemblies 310 , and the two traction assemblies 310 are both provided on one of the mounting plate 4311 and the connecting plate 4312 , or respectively provided on the third hinge shaft 432 and the fourth hinge shaft 433 .

[0128] Exemplarily, the first box door 111 and the second box door 112 corresponding to the third hinge 430 are simultaneously connected to the sliding door mechanism 300, and the two traction components 310 in the two sliding door mechanisms 300 are simultaneously connected to the mounting plate 4311 or the connecting plate 4312, or, partial structures of the two traction components 310 can be respectively connected to the third hinge shaft 432 and the fourth hinge shaft 433.

[0129] Furthermore, in one embodiment, the third hinge 430 is provided with two traction components 310 , one traction component 310 is provided on one of the mounting plate 4311 and the connecting plate 4312 , and the other traction component 310 is provided on one of the third hinge shaft 432 and the fourth hinge shaft 433 .

[0130] Illustratively, the first door 111 and the second door 112 corresponding to the third hinge 430 are both connected to a sliding door mechanism 300, and both sliding door mechanisms 300 include a traction assembly 310, one of which is connected to a mounting plate 4311 or a connecting plate 4312, and the other traction assembly 310 is connected to the third hinge shaft 432 or the fourth hinge shaft 433. For example, a portion of the structure of one traction assembly 310 is connected to the mounting plate 4311, and a portion of the structure of the other traction assembly 310 is connected to the fourth hinge shaft 433.

[0131] For example, as shown in FIG10 , the first door 111 and the second door 112 are respectively connected to a sliding door mechanism 300 , and the traction assemblies 310 in the two sliding door mechanisms 300 can be fixedly connected to the mounting plate 4311 via the same bolt.

[0132] In one embodiment, 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 arranged on the hinge plate, the hinge plate is arranged on the box body 500, and the box door 110 is rotatably arranged on the box body 500 through the hinge shaft; as shown in Figures 11 and 13, 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 plate, the first end of the traction rod 311 is rotatably connected to the first rotating shaft fixing seat 312, and the second end of the traction rod 311 is rotatably connected to the second rotating shaft fixing seat 313; in the process of opening or closing the box door 110, the traction rod 311 drives the sliding door assembly 320 to move, thereby driving the cabinet door 200 to move relative to the width direction of the box door 110.

[0133] For example, the hinge 400 may include a hinge plate and a hinge shaft, with the hinge shaft being fixed to the hinge plate by welding or other means. During actual installation, the hinge plate may be fixed to the housing 500 using bolts or other structures, and the door 110 may be pre-determined with threaded holes. After the hinge plate is fixed to the housing 500, the hinge shaft can be inserted into the hinge hole of the door 110, thereby achieving a rotational connection between the door 110 and the housing 500.

[0134] In the traction assembly 310 , the first rotation shaft fixing seat 312 is set on the sliding door assembly 320 , the second rotation shaft fixing seat 313 is set on the hinge plate, and both ends of the traction rod 311 are rotatably connected to the first rotation shaft fixing seat 312 and the second rotation shaft fixing seat 313 respectively.

[0135] In actual use, when the box door 110 rotates relative to the box body 500 between the positions of opening or closing the storage space, the traction assembly 310 can pull the sliding door assembly 320 to move, 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.

[0136] Furthermore, in one embodiment, in order to enable the sliding door assembly 320 to effectively drive the cabinet door 200 to move relative to the box door 110 under the drive of the traction assembly 310, as shown in Figures 11 and 12, the sliding door assembly 320 includes: a base 321, a first slider 322, a second slider 323 and a connecting member 324.

[0137] 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 set on the first guide rail 3211, and the first shaft fixing seat 312 is connected to the first slider 322; the second slider 323 is slidably set on the second guide rail 3212 and is connected to the cabinet door 200; the two ends of the connecting member 324 are respectively connected to the first slider 322 and the second slider 323.

[0138] During the process of opening or closing the door 110 , the traction rod 311 drives the first slider 322 to move on the first guide rail 3211 , and the first slider 322 drives the second slider 323 to move in the opposite direction on the second guide rail 3212 through the connecting member 324 .

[0139] Exemplarily, the base 321 has a first guide rail 3211 and a second guide rail 3212 arranged side by side and spaced apart. A first slider 322 is disposed on the first guide rail 3211 and is capable of sliding along the length of the first guide rail 3211. A second slider 323 is disposed on the second guide rail 3212 and is capable of sliding along the length of the second guide rail 3212. Furthermore, the first slider 322 and the second slider 323 are connected by a connector 324. When the first slider 322 moves on the first guide rail 3211, the connector 324 pulls the second slider 323 to move on the second guide rail 3212, with the second slider 323 moving in the opposite direction to the first slider 322.

[0140] As a specific implementation, as shown in Figures 11 and 12, two opposing sides of the base 321 in the thickness direction are respectively a first side and a second side, each of which is formed with a U-shaped groove. The U-shaped groove on the first side is a first guide rail 3211, and the U-shaped groove on the second side is a second guide rail 3212. The first guide rail 3211 and the second guide rail 3212 extend along the length of the base 321. The first slider 322 is slidably disposed in the first guide rail 3211, and the second slider 323 is slidably disposed in the second guide rail 3212. Furthermore, the first rotating shaft fixing base 312 is connected to the first slider 322, and the cabinet door 200 can be fixedly connected to the second slider 323.

[0141] Taking into account the needs in actual applications, limiting structures can also be set at the ends on both sides of the first guide rail 3211 and the second guide rail 3212. Through the restriction of the limiting structure, the first slider 322 and the second slider 323 can move within the set moving range, so as to set the moving distance according to needs to meet the usage requirements of different occasions.

[0142] Accordingly, the traction rod 311 is constructed as a long straight rod, a first end of which is rotatably connected to the first rotation shaft fixing seat 312 via a first rotation shaft, and the other end of which is rotatably connected to the second rotation shaft fixing seat 313 via a second rotation shaft. The second rotation shaft fixing seat 313 is fixedly connected to the first slider 322.

[0143] As an implementation, as shown in FIG12 , the first rotating shaft fixing seat 312 includes a first vertical plate and a first horizontal plate, which are connected to each other to form an L-shaped structure. The first horizontal plate is provided with an axial hole, into which the first rotating shaft is inserted. The first end of the traction rod 311 is rotatably connected to the first rotating shaft, thereby being fixedly connected to the first rotating shaft fixing seat 312. The first vertical plate can be fixedly connected to the first slider 322 by welding or other means.

[0144] Similarly, as shown in Figures 11 and 12, the second rotating shaft fixing seat 313 includes a second vertical plate and a second horizontal plate, which are interconnected and form an L-shaped structure. The second horizontal plate is provided with an axial hole, in which a second rotating shaft can be inserted. The second end of the traction rod 311 is rotatably connected to the second rotating shaft, thereby being rotatably connected to the second rotating shaft fixing seat 313.

[0145] To ensure that the first and second sliders 322 and 323 can move synchronously in opposite directions, the connector 324 illustratively includes a first connector 3241 and a second connector 3242. The first and second connectors 3241 and 3242 are configured as flexible ropes. Along the length of the base 321, the first connector 3241 passes around the end of the base 321, with its ends respectively entering the first and second guide rails 3211 and 3212, and connecting to the first and second sliders 322 and 323. Correspondingly, the second connector 3242 passes around the second end of the base 321, with its ends also respectively entering the first and second guide rails 3211 and 3212, and connecting to the first and second sliders 322 and 323. At this point, the two ends of the first connector 3241 are connected to the two ends of the second connector 3242 via the first and second sliders 322 and 323, forming a generally annular structure.

[0146] During actual installation, after the hinge plate is fixed to the housing 500, the second shaft fixing base 313 can be fixed to the hinge plate using bolts or other structures. For example, the second vertical plate in the second shaft fixing base 313 is provided with a through hole. During installation, external bolts can pass through the through hole and connect to the hinge plate, thereby fixing the second vertical plate to the hinge plate.

[0147] Next, the base 321 can be secured to the door 110 using bolts or other structures. For example, two connecting plates 325 are provided on either side of the base 321's length, each with a through-hole. During installation, external bolts can be passed through the through-holes in the connecting plates 325 and connected to the door 110, thereby securing the base 321 to the door 110.

[0148] Afterwards, 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.

[0149] In actual use, as shown in Figures 11 and 12, when the door 110 moves relative to the cabinet body 500 from a position closing the storage space to a position opening the storage space, 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 first guide rail 3211 along the direction A. Correspondingly, the first slider 322 will pull the second slider 323 along the second guide rail 3212 along the direction B through the first connecting member 3241. Since the base 321 is fixedly connected to the door 110 and the second slider 323 is fixedly connected to the cabinet door 200, the cabinet door 200 will move relative to the door 110 along the direction B. The direction A is opposite to the direction B, and both the directions A and B are parallel to the width direction of the door 110.

[0150] Correspondingly, when the door 110 moves relative to the box body 500 from the position of opening the storage space to the position of closing the storage space, during the rotation of the door 110, the first slider 322 will move on the first guide rail 3211 in a direction opposite to direction A. Accordingly, the first slider 322 will pull the second slider 323 on the second guide rail 3212 in a direction opposite to direction B through the second connecting member 3242. At this time, the cabinet door 200 will move relative to the door 110 in a direction opposite to direction B.

[0151] Furthermore, in another specific implementation, as shown in Figures 13 to 15, the base 321 is constructed as a plate-like structure with a certain length, and the first guide rail 3211 and the second guide rail 3212 are respectively arranged on both sides of the width direction of the base 321. Moreover, the first guide rail 3211 and the second guide rail 3212 are both extended along the length direction of the base 321, and 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.

[0152] In some embodiments, the traction assembly includes: a first connecting rod and a second connecting rod. The first end of the first connecting rod is rotatably disposed on the hinge 400 , for example, on a hinge plate of the hinge 400 .

[0153] The first end of the first connecting rod is rotatably mounted within the mounting area, for example, via a rotating shaft mount. 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 mounted to the door 110 and meshes with the teeth on the first slider 322 via a gear disposed on the second end of the second connecting rod.

[0154] It is understandable that the first connecting rod and the second connecting rod are connected by a hinge, and the first connecting rod and the second connecting rod can rotate relative to each other. The first connecting rod can rotate relative to the box body 500, and the second connecting rod can rotate relative to the box door 110.

[0155] When the second end of the second connecting rod makes a circular motion with the cabinet door 110 with the hinge axis as the center, since the first end of the first connecting rod is staggered with the hinge axis, the distance between the second end of the second connecting rod and the first end of the first connecting rod changes, while the position of the second end of the second connecting rod relative to the cabinet door 110 remains unchanged, which causes the second end of the second connecting rod to rotate around the cabinet door 110 and drives the second slider 323 to drive the cabinet door 200 to move along the width direction of the cabinet door 110.

[0156] In actual application, during the opening process of the door 110, the door 110 drives the second end of the second connecting rod to rotate relative to the hinge axis. Based on the staggered arrangement of the first end of the first connecting rod and the hinge axis, the distance between the first end of the first connecting rod and the second end of the second connecting rod increases, driving the second end of the second connecting rod to rotate clockwise relative to the door 110, thereby controlling the second slider 323 to drive the cabinet door 200 to move along the width direction of the door 110 in the direction away from the hinge 400, that is, to move to the left relative to the door 110, so as to avoid interference between the cabinet door 200 and the cabinet door 200 of the side cabinet; During the closing process of the door 110, the second end of the second connecting rod is driven to rotate relative to the hinge axis. Based on the staggered arrangement of the first end of the first connecting rod and the hinge axis, the distance between the first end of the first connecting rod and the second end of the second connecting rod is reduced, driving the second end of the second connecting rod to rotate counterclockwise relative to the door 110, thereby controlling the second slider 323 to drive the cabinet door 200 to move along the width direction of the door 110 toward the direction close to the hinge 400, that is, to move to the right relative to the door 110. This ensures that when the door 110 is closed, the cabinet door 200 can avoid the cabinet door 200 of the cabinet on the side and reset the cabinet door 200.

[0157] In an optional embodiment, the first rotating shaft fixing base 312 is connected to the first slider 322, and the cabinet door 200 can be fixedly connected to the second slider 323. The first guide rail and the second guide rail serve as a kind of track, and the first slider 322 and the second slider 323 are sliding members adapted to and slidable along the corresponding guide rails. Furthermore, the sliding engagement between the first slider 322 and the first guide rail should at least include a situation where a ball bearing is disposed between the first slider 322 and the first guide rail, and the sliding engagement between the second slider 323 and the second guide rail should at least include a situation where a ball bearing is disposed between the second slider 323 and the second guide rail.

[0158] Accordingly, the traction rod 311 may be constructed as an arc-shaped rod, one end of the traction rod 311 being rotatably connected to the first rotation shaft fixing seat 312 via a first rotation shaft, and the other end of the traction rod 311 being rotatably connected to the second rotation shaft fixing seat 313 via a second rotation shaft.

[0159] As an implementation, as shown in Figures 14 and 15 , the first rotating shaft fixing seat 312 is provided with a first clamping portion, which includes two clamping plates spaced side by side. The two clamping plates are respectively provided with pin holes, and the first rotating shaft is simultaneously inserted into the two pin holes. 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 welding or other means.

[0160] Similarly, as shown in Figures 13 and 15, a second clamping portion is provided on the second rotating shaft fixing seat 313, and the second clamping portion also includes two clamping plates arranged side by side and spaced apart. 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 second 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, thereby, the traction rod 311 can be rotatably connected to the second rotating shaft fixing seat 313.

[0161] The first slider 322 and the second slider 323 are connected to each other via a connecting member 324. The first slider 322 can drive the second slider 323 to move in the opposite direction with the help of the connecting member 324 during the movement.

[0162] During actual installation, after the hinge plate is fixed to the housing 500, the second shaft fixing base 313 can be fixed to the hinge plate using bolts or other structures. For example, the second shaft fixing base 313 is provided with a through hole, and during installation, an external bolt can be passed through the through hole and connected to the hinge plate, thereby fixing the second shaft fixing base 313 to the hinge plate.

[0163] Next, the base 321 can be secured to the door 110 using bolts or other structures. For example, a first receiving plate 326 and a second receiving plate 327 are provided on either side of the base 321's length, each with a through-hole. During installation, external bolts can be passed through the through-holes in the first and second receiving plates 326, 327 and connected to the door 110, thereby securing the base 321 to the door 110.

[0164] Afterwards, 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.

[0165] In actual use, as shown in Figures 13 and 14, when the door 110 moves relative to the cabinet body 500 from a position closing the storage space to a position opening the storage space, the first rotation axis 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 first guide rail 3211 along the C direction. Correspondingly, the first slider 322 will pull the second slider 323 along the second guide rail 3212 along the D direction 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, the cabinet door 200 will move relative to the door 110 along the D direction. 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.

[0166] Correspondingly, when the door 110 moves relative to the box body 500 from the position of opening the storage space to the position of closing the storage space, during the rotation of the door 110, the first slider 322 will move on the first guide rail 3211 in a direction opposite to the direction C. Accordingly, the first slider 322 will pull the second slider 323 on the second guide rail 3212 in a direction opposite to the direction D through the connecting member 324. At this time, the cabinet door 200 will move relative to the door 110 in a direction opposite to the direction D.

[0167] Furthermore, in one embodiment, to ensure that the first slider 322 can effectively drive the second slider 323 to move in the opposite direction, as shown in FIG. 13 to FIG. 15 , the connecting member 324 includes: a first connecting member 3241 and a second connecting member 3242 .

[0168] Among them, the first connecting member 3241 bypasses one end 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 of the base 321, and its two ends are respectively connected to the second ends of the first slider 322 and the second slider 323.

[0169] Exemplarily, the first connecting member 3241 can be a flexible rope, and 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 passing around one end of the base 321, that is, in the length direction of the base 321, the first connecting member 3241 passes around one end of the base 321, and its two ends extend toward the first slider 322 and the second slider 323, respectively, and are respectively connected to the first slider 322 and the second slider 323.

[0170] 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 second end of the base 321, and its two ends are also connected to the first slider 322 and the second slider 323 respectively.

[0171] At this time, both ends of the first connecting member 3241 are connected to both ends of the second connecting member 3242 via the first slider 322 and the second slider 323 respectively, and form a substantially ring structure.

[0172] For example, 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 shown in Figure 15, the first roller 328 and the second roller 329 are respectively provided on both sides of the length direction of the base 321, and the first roller 328 and the second roller 329 can respectively support the first connecting member 3241 and the second connecting member 3242.

[0173] As shown in FIG15 , there are two first rollers 328 , spaced apart along the width of the base 321 . Furthermore, the two first rollers 328 can be rotatably mounted on the first receiving plate 326 . To facilitate receiving the first connector 3241 , the outer periphery of the first rollers 328 can be provided with a receiving groove along its circumference. Thus, when the first connector 3241 is installed, it can be positioned within the receiving grooves of the two first rollers 328 . Thereafter, when the first slider 322 pulls the second slider 323 via the first connector 3241 , the first connector 3241 can drive the two first rollers 328 to rotate.

[0174] Similarly, there are two second rollers 329, spaced apart along the width of the base 321. Furthermore, the two second rollers 329 can be rotatably mounted on the second receiving plate 327. To facilitate receiving the second connector 3242, the outer periphery of the second rollers 329 can also be provided with a receiving groove along its circumference. Thus, when the second connector 3242 is installed, it can be positioned within the receiving grooves of the two second rollers 329. Thereafter, when the first slider 322 pulls the second slider 323 via the second connector 3242, the second connector 3242 can drive the two second rollers 329 to rotate.

[0175] Therefore, in the above-mentioned setting method, the first roller 328 can be used to support and limit the first connecting member 3241, and the second roller 329 can be used to support and limit the second connecting member 3242. The first roller 328 and the second roller 329 can prevent the first connecting member 3241 and the second connecting member 3242 from contacting other components during the movement and causing wear and consumption, and can effectively protect the first connecting member 3241 and the second connecting member 3242.

[0176] In addition, as described above, a refrigeration device is also provided in this embodiment, which includes a box body 500 and the door body device described in the above embodiment, wherein 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, which is suitable for opening or closing the storage space of the box body 500.

[0177] Finally, it should be noted that the terms "parallel" and "perpendicular" in the embodiments of this application should not be strictly limited to 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 this application.
