[0042] like Figure 2As shown, the door device in this embodiment of the invention includes: a box door 100, a cabinet door 200, and a sliding door mechanism 300. The box door 100 is rotatably connected to a box body 500 via a single-axis hinge 400, and is suitable for opening or closing the storage space of the box body 500. The cabinet door 200 is slidably disposed on the outside of the box door 100. The sliding door mechanism 300 includes a traction component 310 and a sliding door component 320 connected together. The traction component 310 is disposed on the front of the box body 500, and the sliding door component 320 is disposed on the box door 100 and connected to the cabinet door 200. The traction component 310 is configured to drive the sliding door component 320 to move during the opening or closing of the box door 100, thereby causing the cabinet door 200 to move relative to the width direction of the box door 100.

[0043] The thickness of the cabinet door 100 is 18-60mm, and for example, the thickness of the cabinet door 100 is 18mm, 25mm, 50mm, 60mm, etc. The thickness of the cabinet door 200 is 12-26mm, and for example, the thickness of the cabinet door 200 is 12mm, 18mm, 24mm, 26mm, etc. In addition, the cabinet door 200 can be a wooden door or a plastic door, etc.

[0044] It is understood that the door device in this embodiment can be used in refrigeration equipment such as refrigerators, freezers, and ice makers. This refrigeration equipment includes a cabinet 500, which forms a storage space for storing items such as vegetables and fruits that require refrigeration or freezing. Optionally, the cabinet 500 of the refrigeration equipment may also be equipped with a refrigeration device that can refrigerate the storage space.

[0045] In this embodiment, the door 100 in the door device can be rotatably mounted on the cabinet 500 of the refrigeration equipment via the hinge 400. The door 100 can be used to open or close the storage space in the cabinet 500. When the door 100 is in the closed position of closing the storage space, the storage space is in a closed state, and the items in the storage space can be refrigerated. When the door 100 is in the open position of opening the storage space, the storage space is in an open state, and the user can take out the items in the storage space.

[0046] To facilitate the description of the positional relationships between the various components, in this embodiment, as follows: Figure 2 As shown, the box 500 is generally constructed as a cuboid structure with a certain height. The box 500 can be placed on a horizontal surface. The box 500 has a height direction, a width direction and a thickness direction that are perpendicular to each other. The height direction of the box 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.

[0047] The interior of the box 500 is provided with a storage space. An opening is provided on the side of the box 500 in the thickness direction, which connects to the storage space. The box door 100 is connected to the side of the box 500 in the thickness direction where the opening is provided. The box door 100 extends along the width direction of the box 500. A hinge 400 is connected to the box door 100 on one side of the box 500 in the width direction. The box door 100 can be rotated to the box 500 via the hinge 400, thereby ensuring that the box door 100 can open or close the storage space of the box 500.

[0048] Furthermore, the side of the box 500 where the box door 100 is installed is the front, that is, the box door 100 is installed on the front of the box 500.

[0049] The door 100 is generally constructed as a flat plate structure with a certain thickness. The door 100 has mutually perpendicular height, width, and thickness directions. The height direction of the door 100 is parallel to the vertical direction, while the width and length directions are located in a horizontal plane and are perpendicular to each other. One side of the door 100 in the width direction can be rotatably connected to the box body 500 via a hinge 400. For example, as... Figure 2 As shown, the door 100 is connected to the right side of the box body 500 in the width direction by a hinge 400, and the door 100 can be rotatably connected to the box body 500 via the hinge 400.

[0050] Furthermore, when the door 100 is in the position of closing the storage space of the box 500, the width direction of the door 100 is parallel to the width direction of the box 500, and the thickness direction of the door 100 is parallel to the thickness direction of the box 500.

[0051] 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 outer side of the box door 100 away from the box body 500. When the refrigeration equipment is embedded in the cabinet or placed directly in the cabinet, the cabinet door 200 can be flush with the cabinet door panel when the box door 100 is in the closed position. That is, the outer wall of the cabinet door 200 away from the box door 100 can be flush with the outer wall of the cabinet.

[0052] In practical applications, the outer wall of the cabinet door 200 can be made of the same material and shape as the outer wall of the cabinet, and can be decorated with the same decorations, so that the refrigeration equipment can be sufficiently coordinated with the cabinet and ensure aesthetics.

[0053] In this embodiment, the door device is installed after the cabinet 500 of the refrigeration equipment. When the cabinet door 100 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 100 in the width direction. Thus, when the refrigeration equipment is placed in the cabinet in an embedded manner, while ensuring coordination and aesthetics and not affecting the user experience, the cabinet door 200 can be prevented from interfering with the cabinet during the opening of the cabinet door 100.

[0054] In one embodiment, such as Figure 1 As shown, the door assembly and the cabinet 500 are configured to be disposed within the installation space formed between the first cabinet 510 and the second cabinet 520; during the opening or closing of the cabinet door 100, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the cabinet door 100 so that the cabinet door 200 avoids the side walls of the first cabinet 510 and the second cabinet 520. Alternatively, the door assembly and the cabinet 500 are configured to be housed within the cabinet; during the opening or closing of the cabinet door 100, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the cabinet door 100 so that the cabinet door 200 avoids the side wall of the cabinet.

[0055] It is understood that the refrigeration equipment includes the door assembly and the cabinet 500.

[0056] In practice, such as Figure 1 As shown, when a refrigeration device having the door assembly and cabinet 500 is placed between adjacent first cabinets 510 and second cabinets 520, a cabinet door 200 can be provided on the outer side of the cabinet door 100 in the door assembly. The cabinet door 200 can move relative to the cabinet door 100 along the width direction of the cabinet door 100. Optionally, when the cabinet door 100 is in the state of closing the storage space of the cabinet 500, the outer wall surface of the cabinet door 200 away from the cabinet door 100 can be flush with the outer wall surfaces of the first cabinet 510 and second cabinets 520. The outer wall surfaces of the first cabinet 510 and second cabinets 520 and the outer wall surface of the cabinet door 200 away from the cabinet door 100 are in the same direction in the thickness direction of the cabinet 500.

[0057] At this time, as the cabinet door 100 rotates relative to the cabinet body 500, the sliding door mechanism 300 can drive the cabinet door 200 to move, thereby allowing the cabinet door 200 to avoid the side walls of the first cabinet body 510 and the second cabinet body 520.

[0058] Alternatively, after the refrigeration equipment is placed in the cabinet, a cabinet door 200 can be provided on the outside of the cabinet door 100 of the door assembly, and the cabinet door 200 can move relative to the cabinet door 100. Optionally, when the cabinet door 100 is in the closed storage space of the cabinet 500, the outer wall surface of the cabinet door 200 away from the cabinet door 100 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 away from the cabinet door 100 are in the same direction in the thickness direction of the cabinet 500.

[0059] At this time, as the cabinet door 100 rotates relative to the cabinet body 500, the sliding door mechanism 300 can drive the cabinet door 200 to move, which also allows the cabinet door 200 to avoid the side wall of the cabinet body.

[0060] Furthermore, in one embodiment, there are multiple cabinet doors 100, each cabinet door 100 corresponding to at least one storage space; each cabinet door 100 is rotatably connected to the cabinet body 500 by multiple hinges 400, and a traction assembly 310 is provided near at least one of the multiple hinges 400 corresponding to each cabinet door 100.

[0061] It is understandable that, depending on different refrigeration needs, the cabinet 500 of different refrigeration equipment can be set with different numbers of storage spaces. These storage spaces are spaced apart along the height of the cabinet 500. Some storage spaces are used for refrigeration, and some storage spaces are used for freezing. Accordingly, in order to close these storage spaces in a targeted manner, there can be multiple cabinet doors 100, and each cabinet door 100 corresponds to at least one of the storage spaces.

[0062] For example, such as Figure 2 As shown, the cabinet 500 has two storage compartments spaced apart vertically, which can be used for refrigeration and freezing respectively. There are two doors 100, namely the first door 110 and the second door 120, and the positions of the two doors 100 correspond one-to-one with the two storage compartments. At this time, the two storage compartments can be opened or closed independently through the two doors 100.

[0063] For example, the cabinet 500 can have three storage compartments arranged vertically at intervals: a first compartment, a second compartment, and a third compartment. The first and second compartments are used for refrigeration, and the second compartment is used for freezing. There are two doors 100: a first door 110 and a second door 120. The first door 110 corresponds one-to-one with the positions of the first and second compartments, while the second door 120 corresponds to the position of the third compartment. In this case, the first door 110 can be used to simultaneously open or close the first and second compartments, while the second door 120 can be used to independently control the opening and closing of the third compartment.

[0064] It is understood that in this embodiment, each door 100 can correspond to a single storage space, in which case the door 100 can control the opening and closing state of the storage space independently. In actual use, depending on the needs, each door 100 can also correspond to multiple adjacent storage spaces, in which case the door 100 can control the opening and closing state of the multiple storage spaces simultaneously.

[0065] In practical applications, when there are multiple doors 100, these multiple doors 100 can be spaced apart along the height direction of the box body 500. At this time, the door 100 located at the top can be rotatably connected to the box body 500 via the first hinge 410, and the door 100 located at the bottom can be rotatably connected to the box body 500 via the third hinge 430.

[0066] Therefore, by setting the first hinge 410 and the third hinge 430, the top and bottom doors 100 can be opened or closed respectively for their respective storage spaces.

[0067] In order to effectively realize the installation of the door 100, the hinge 400 may also include a second hinge 420, wherein the second hinge 420 is disposed on the front of the housing 500 and is located between the first hinge 410 and the third hinge 430.

[0068] For example, since multiple cabinet doors 100 are spaced apart along the height direction of the cabinet body 500, a second hinge 420 may be provided between two adjacent cabinet doors 100, and at least one of the two adjacent cabinet doors 100 can be rotatably connected to the cabinet body 500 by means of the second hinge 420.

[0069] In practical applications, the number of second hinges 420 can be one or two. For example, when there is one second hinge 420, the two adjacent cabinet doors 100 can be simultaneously connected to the second hinge 420 and rotatably connected to the cabinet body 500 via the single second hinge 420. When there are two second hinges 420, the two second hinges 420 can be spaced apart along the height direction of the cabinet body 500. In this case, the two adjacent cabinet doors 100 can be hinged to the two second hinges 420 respectively, and then rotatably connected to the cabinet body 500 via their respective second hinges 420.

[0070] For example, such as Figure 2As shown, when the door assembly includes a first door 110 and a second door 120, the first door 110 is rotatably connected to the housing 500 via a first hinge 410 and a second hinge 420, and the second door 120 is rotatably connected to the housing 500 via a second hinge 420 and a third hinge 430. In this case, a traction assembly 310 is provided near the first hinge 410 corresponding to the first door 110, and the traction assembly 310 is located on the upper crossbeam 501; or, a traction assembly 310 is provided near the second hinge 420 corresponding to the first door 110, and the traction assembly 310 is located on the middle crossbeam 502; or, a traction assembly 310 is provided near the second hinge 420 corresponding to the second door 120, and the traction assembly 310 is located on the middle crossbeam 502; or, a traction assembly 310 is provided near the third hinge 430 corresponding to the second door 120, and the traction assembly 310 is located on the lower crossbeam 503. In other words, the first door 110 can be equipped with one or two traction components 310, and the second door 120 can be equipped with one or two traction components 310.

[0071] Furthermore, in one embodiment, such as Figure 6 As shown, the first hinge 410 includes a first hinge plate 411 and a first hinge shaft 412. A portion of the first hinge plate 411 covers the top wall of the housing 500, and the remaining portion protrudes from the top wall toward the first door 110. The first hinge shaft 412 extends downward from the portion of the first hinge plate 411 that protrudes from the top wall. The top of the first door 110 is hinged to the first hinge shaft 412. The traction assembly 310 is disposed in the first mounting area A, which is located close to the first hinge plate 411.

[0072] For example, the first hinge plate 411 and the first hinge shaft 412 can be made of metal or non-metal materials with a certain structural strength. The first hinge plate 411 includes a first fitting part and a first protrusion that are connected to each other. The first fitting part is provided with a plurality of mounting holes. The first hinge shaft 412 is fixedly mounted on the first protrusion by means of welding or threaded connection.

[0073] During actual installation, multiple threaded holes can be pre-set on the top wall of the housing 500. Then, the first fitting part of the first hinge plate 411 is fitted to the top wall of the housing 500, and the mounting holes on the first fitting part are aligned with the threaded holes. The first fitting part is then fixed to the top wall of the housing 500 with bolts. At this time, the first fitting part can cover and fit to the top wall of the housing 500, the first protrusion can protrude from the top wall toward the door 100, and the first hinge shaft 412 can extend downward along the height direction of the housing 500.

[0074] Based on this, when installing the door 100, a hinge hole can be set on the top of the door 100 corresponding to the first hinge 410 in advance, and then the first hinge shaft 412 can be inserted into the hinge hole, thereby realizing the installation of the door 100.

[0075] Correspondingly, such as Figure 2 As shown, the traction assembly 310 located on the upper crossbeam 501 of the housing 500 is positioned close to the first hinge 410. Under the action of the traction assembly 310, the sliding door assembly 320 can drive the cabinet door 200 corresponding to the first cabinet door 110 to move relative to the width direction of the first cabinet door 110.

[0076] Thus, the traction assembly 310 located on the upper crossbeam 501 of the housing 500 is positioned close to the first hinge plate 411. Furthermore, as... Figure 3 As shown, the traction assembly 310 is disposed in the first installation area A. The first installation area A includes a first side, a second side, a third side, and a fourth side. The first side and the third side are disposed opposite to each other, and the second side and the fourth side are disposed opposite to each other. The first side is located in the plane where the first hinge plate 411 is located, and the second side is located in the plane where the side of the housing 500 is located. In the height direction of the housing 500, a first distance is left between the third side and the first side; in the width direction of the housing 500, a second distance is left between the fourth side and the second side.

[0077] In an optional embodiment, the first distance is greater than zero and less than or equal to 60 mm, and the second distance is greater than zero and less than or equal to 100 mm. For example, the second distance is 20 mm, 40 mm, 60 mm, 80 mm, or 100 mm, and the first distance is 20 mm, 30 mm, 50 mm, or 60 mm.

[0078] Furthermore, in one embodiment, such as Figure 7 As shown, the second hinge 420 includes a second hinge plate 421, a second hinge shaft 422, and a third hinge shaft 423. The second hinge plate 421 includes a mounting plate 4211 and a connecting plate 4212. The mounting plate 4211 is mounted on the front side (middle crossbeam 502) of the housing 500. The connecting plate 4212 is connected to the side of the mounting plate 4211 away from the front side of the housing 500. The connecting plate 4212 and the mounting plate 4211 are set at an angle. The connecting plate 4212 has a first side and a second side opposite to each other. The second hinge shaft 422 is set on the first side. The bottom of the first door 110 is hinged to the second hinge shaft 422. The second hinge shaft 422 is set on the second side. The top of the second door 120 is hinged to the second hinge shaft 422.

[0079] For example, the second hinge plate 421 can be made of a metal or non-metal material with a certain structural strength. The second hinge plate 421 includes an interconnected mounting plate 4211 and a connecting plate 4212. The connecting plate 4212 is generally perpendicular to the mounting plate 4211, and the mounting plate 4211 is provided with multiple mounting holes. In actual manufacturing, the mounting plate 4211 and the connecting plate 4212 can be integrally formed on the same sheet metal. Then, the connecting plate 4212 can be bent relative to the mounting plate 4211 by stamping and folding.

[0080] The two sides of the connecting plate 4212 in the thickness direction are the first side and the second side, respectively. The first side is fixedly connected to the first hinge shaft 412, and the second side is fixedly connected to the second hinge shaft 422.

[0081] In actual manufacturing, the second hinge shaft 422 and the third hinge shaft 423 can be fixedly connected to the connecting plate 4212 by welding. Alternatively, the second hinge shaft 422 and the third hinge shaft 423 can be constructed as a single long rod-shaped component. The connecting plate 4212 is provided with a through hole extending along its thickness direction. The single component is inserted into the through hole and fixed in the through hole by welding or threaded connection. The two ends of the single component in the length direction on the connecting plate 4212 are respectively formed as the second hinge shaft 422 and the third hinge shaft 423.

[0082] During actual installation, multiple threaded holes can be pre-set on the front of the enclosure 500 according to the installation position of the door 100, for example, such as Figure 2 As shown, multiple threaded holes are provided on the front of the box 500 corresponding to the gap between the first box door 110 and the second box door 120. Then, the mounting holes on the mounting plate 4211 of the first hinge plate 411 are aligned with the threaded holes. The mounting plate 4211 is then fixed to the front of the box 500 with bolts. At this time, the connecting plate 4212 extends toward the box door 100. Meanwhile, the first hinge shaft 412 extends upward along the height direction of the box 500, and the second hinge shaft 422 extends downward along the height direction of the box 500.

[0083] Based on this, when installing the box door 100, a hinge hole can be provided in advance at the bottom of the first box door 110 corresponding to the second hinge shaft 422, and a hinge hole can be provided in advance at the top of the second box door 120 corresponding to the third hinge shaft 423. Then, the first hinge shaft 412 and the second hinge shaft 422 can be inserted into the hinge holes of their respective box doors 100, thereby realizing the installation of the box door 100.

[0084] Thus, the traction assembly 310 located on the middle crossbeam 502 of the housing 500 is positioned close to the mounting plate 4211.

[0085] like Figure 4 As shown, when the second installation area B is located above the mounting plate 4211, the second installation area B includes a first side, a second side, a third side, and a fourth side. The first side and the third side are arranged opposite each other, and the second side and the fourth side are arranged opposite each other. The first side is the top edge of the mounting plate 4211, and the second side is located in the plane where the side of the box 500 is located. In the height direction of the box 500, there is a third distance between the third side and the first side; in the width direction of the box 500, there is a fourth distance between the fourth side and the second side. At this time, the traction component 310 corresponding to the first box door 110 is located in the second installation area B.

[0086] When the second mounting area B is located below the mounting plate 4211, the second mounting area B includes a first side, a second side, a third side, and a fourth side. The first and third sides are arranged opposite each other, and the second and fourth sides are arranged opposite each other. The first side is the bottom edge of the mounting plate 4211, and the second side is located in the plane containing the side of the housing 500. In the height direction of the housing 500, a fifth distance is left between the third side and the first side; in the width direction of the housing 500, a sixth distance is left between the fourth side and the second side. At this time, the traction assembly 310 corresponding to the second door 120 is located within the second mounting area B.

[0087] In an optional embodiment, the third distance is greater than zero and less than or equal to 60 mm, and the fourth distance is greater than zero and less than or equal to 100 mm. For example, the fourth distance is 20 mm, 40 mm, 60 mm, 80 mm, or 100 mm, and the third distance is 20 mm, 30 mm, 50 mm, or 60 mm.

[0088] The fifth distance is greater than zero and less than or equal to 60mm, and the sixth distance is greater than zero and less than or equal to 100mm. For example, the sixth distance is 20mm, 40mm, 60mm, 80mm, and 100mm, and the fifth distance is 20mm, 30mm, 50mm, and 60mm.

[0089] Furthermore, in one embodiment, such as Figure 8 As shown, the third hinge 430 includes a third hinge plate 431 and a fourth hinge shaft 432. The third hinge plate 431 includes a support plate 4311 and an extension plate 4312. The support plate 4311 is installed on the front of the housing 500. The extension plate 4312 is connected to the side of the support plate 4311 away from the front of the housing 500. The support plate 4311 and the extension plate 4312 are set at an angle. The fourth hinge shaft 432 is set on the top surface of the extension plate 4312 and extends upward. The bottom of the second door 120 is hinged to the third hinge shaft 423.

[0090] Similarly, the third hinge plate 431 can also be made of metal or non-metal materials with a certain structural strength. The second hinge plate 421 includes a support plate 4311 and an extension plate 4312 connected to each other. The extension plate 4312 is approximately perpendicular to the support plate 4311. The two can be integrally formed by stamping or other methods. The support plate 4311 is provided with multiple mounting holes. The fourth hinge shaft 432 is fixedly mounted on the extension plate 4312 by welding or threaded connection or other methods.

[0091] During actual installation, multiple threaded holes can be pre-set on the front of the housing 500 near the bottom. Then, one side of the support plate 4311 in the thickness direction is attached to the front of the housing 500. Next, the mounting holes on the support plate 4311 are aligned with the threaded holes. Then, the support plate 4311 is fixed to the front of the housing 500 with bolts. The extension plate 4312 is connected to the other side of the support plate 4311 in the thickness direction and extends toward the direction of the door 100. In addition, the fourth hinge shaft 432 extends upward along the height direction of the housing 500.

[0092] Based on this, when installing the door 100, a hinge hole can be set at the bottom of the door 100 corresponding to the second hinge 420 in advance, and then the fourth hinge shaft 432 can be inserted into the hinge hole, thereby realizing the installation of the door 100.

[0093] Thus, the traction assembly 310 located on the lower crossbeam 503 of the housing 500 is positioned close to the second hinge plate 421. Figure 5 As shown, the traction component 310 is disposed in the third installation area C. In other words, the traction component 310 corresponding to the second door 120 is disposed in the third installation area C. The third installation area C includes a first side, a second side, a third side, and a fourth side. The first side and the third side are disposed opposite to each other, and the second side and the fourth side are disposed opposite to each other. The first side supports the top edge of the plate 4311. The second side is located in the plane where the side of the box 500 is located. In the height direction of the box 500, a seventh distance is left between the third side and the first side; in the width direction of the box 500, an eighth distance is left between the fourth side and the second side.

[0094] In an optional embodiment, the seventh distance is greater than zero and less than or equal to 60 mm, and the eighth distance is greater than zero and less than or equal to 100 mm. For example, the eighth distance is 20 mm, 40 mm, 60 mm, 80 mm, or 100 mm, and the seventh distance is 20 mm, 30 mm, 50 mm, or 60 mm.

[0095] In a specific embodiment, such as Figure 2As shown, the box body 500 has two storage spaces spaced apart along its height. A first hinge 410 is located at the top of the box body 500, a third hinge 430 is located at the bottom of the box body 500, and a second hinge 420 is located in the middle of the box body 500, approximately between the two storage spaces. The door assembly includes two doors 100, namely a first door 110 and a second door 120, which are spaced apart along the height of the box body 500. The first door 110 and the second door 120 correspond to the two storage spaces of the box body 500, respectively. During installation, the top of the first door 110 is hinged to the first hinge axis 412 of the first hinge 410, the bottom of the first door 110 is hinged to the second hinge axis 422 of the second hinge 420, the top of the second door 120 is hinged to the third hinge axis 423 of the second hinge 420, and the bottom of the second door 120 is hinged to the fourth hinge axis 432 of the third hinge 430. Thus, through this arrangement, the first door 110 and the second door 120 can be rotatably connected to the housing 500.

[0096] In one embodiment, to ensure that the traction assembly 310 can drive the sliding door assembly 320 to move, the traction assembly 310 includes a traction rod 311, a first pivot fixing seat 312, and a second pivot fixing seat 313. The first pivot fixing seat 312 is connected to the sliding door assembly 320, and the second pivot fixing seat 313 is connected to the front of the cabinet 500. One end of the traction rod 311 is rotatably connected to the first pivot fixing seat 312, and the other end of the traction rod 311 is rotatably connected to the second pivot fixing seat 313. During the opening or closing of the cabinet door 100, the traction rod 311 drives the sliding door assembly 320 to move, thereby causing the cabinet door 200 to move relative to the width direction of the cabinet door 100. The second pivot fixing seat 313 is located within the installation area (first installation area A, second installation area B, and third installation area C). For example, the second pivot fixing seat 313 is installed in the installation area by screws.

[0097] For example, the hinge 400 may include a hinge plate and a hinge shaft, with the hinge shaft fixedly mounted on the hinge plate by welding or other means. During actual installation, the hinge plate can be fixed to the housing 500 using bolts or similar structures. The door 100 may have pre-drilled threaded holes. After the hinge plate is fixed to the housing 500, the hinge shaft can be inserted into the hinge holes of the door 100, thereby achieving a rotatable connection between the door 100 and the housing 500.

[0098] In the traction assembly 310, the first pivot fixing seat 312 is disposed on the sliding door assembly 320, and the second pivot fixing seat 313 is disposed on the front and close to the hinge plate. The two ends of the traction rod 311 are rotatably connected to the first pivot fixing seat 312 and the second pivot fixing seat 313, respectively.

[0099] In actual use, when the cabinet door 100 rotates relative to the cabinet body 500 between the open and closed storage space positions, the traction component 310 can pull the sliding door component 320 to move, thereby causing the sliding door component 320 to drive the cabinet door 200 to move relative to the cabinet door 100 in the width direction of the cabinet door 100.

[0100] Furthermore, in one embodiment, in order for the sliding door assembly 320 to effectively move the cabinet door 200 relative to the box door 100 under the drive of the traction assembly 310, such as... Figure 9 and Figure 10 As shown, the sliding door assembly 320 includes: a base 321, a first slider 322, a second slider 323, and a connector 324.

[0101] Specifically, a first guide rail is formed on one side of the base 321 and a second guide rail is formed on the other side; a first slider 322 is slidably disposed on the first guide rail, and a first rotating shaft fixing seat 312 is connected to the first slider 322; a second slider 323 is slidably disposed on the second guide rail and is connected to the cabinet door 200; the two ends of the connector 324 are respectively connected to the first slider 322 and the second slider 323.

[0102] During the opening or closing of the door 100, the traction rod 311 drives the first slider 322 to move on the first guide rail, and the first slider 322 drives the second slider 323 to move in the opposite direction on the second guide rail through the connector 324.

[0103] For example, the base 321 has a first guide rail and a second guide rail arranged side by side and spaced apart. A first slider 322 is disposed on the first guide rail and is slidable along the length direction of the first guide rail. A second slider 323 is disposed on the second guide rail and is slidable along the length direction of the second guide rail. 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, the first slider 322 can pull the second slider 323 to move on the second guide rail via the connector 324, and the direction of movement of the second slider 323 is opposite to the direction of movement of the first slider 322.

[0104] As a specific implementation method, such as Figure 9 and Figure 10As shown, the base 321 has a first side and a second side on opposite sides along its thickness direction. Each side has a U-shaped groove. The U-shaped groove on the first side serves as a first guide rail, and the U-shaped groove on the second side serves as a second guide rail. The first and second guide rails extend along the length of the base 321. A first slider 322 is slidably disposed in the first guide rail, and a second slider 323 is slidably disposed in the second guide rail. Furthermore, a first rotating shaft fixing seat 312 is connected to the first slider 322, and the cabinet door 200 is fixedly connected to the second slider 323.

[0105] Considering the needs of practical applications, limiting structures can also be provided at the ends of the first and second guide rails. By limiting the first slider 322 and the second slider 323, the movement range can be set so that the movement distance can be set according to the requirements to meet the usage requirements of different occasions.

[0106] Accordingly, the traction rod 311 is constructed as a long straight rod, with one end of the traction rod 311 rotatably connected to the first rotating shaft fixing seat 312 via the first rotating shaft, and the other end rotatably connected to the second rotating shaft fixing seat 313 via the second rotating shaft.

[0107] As one implementation method, such as Figure 10 As shown, 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 a shaft hole, in which a first rotating shaft is inserted. One 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 methods.

[0108] Similarly, such as Figure 9 and Figure 10 As shown, the second rotating shaft fixing seat 313 includes a second vertical plate and a second horizontal plate. The second vertical plate and the second horizontal plate are connected to each other and form an L-shaped structure. The second horizontal plate is provided with a shaft hole, in which a second rotating shaft can be inserted. The other end of the traction rod 311 is rotatably connected to the second rotating shaft, thereby rotatably connecting with the second rotating shaft fixing seat 313.

[0109] To ensure that the first slider 322 and the second slider 323 can move synchronously in opposite directions, the connector 324, exemplarily, includes a first connector 3241 and a second connector 3242, which are constructed as flexible ropes. Along the length of the base 321, the first connector 3241 passes around one end of the base 321, with its two ends entering the first and second guide rails respectively, and connecting to the first slider 322 and the second slider 323 respectively. Correspondingly, the second connector 3242 passes around the other end of the base 321, with its two ends also entering the first and second guide rails respectively, and connecting to the first slider 322 and the second slider 323 respectively. In this case, the two ends of the first connector 3241 are connected to the two ends of the second connector 3242 via the first slider 322 and the second slider 323, forming a generally annular structure.

[0110] In actual installation, after the hinge plate is fixedly installed on the housing 500, the second rotating shaft fixing seat 313 can be fixed on the front of the housing 500 with the help of bolts or other structures.

[0111] Next, the base 321 can be fixed to the door 100 using bolts or similar structures. For example, a connecting plate 325 is provided on each side of the base 321 along its length, and each of the two connecting plates 325 has a through hole. During installation, external bolt holes can pass through the through holes on the two connecting plates 325 and connect to the door 100, thereby fixing the base 321 to the door 100.

[0112] Next, 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-fit ​​structures.

[0113] In practical use, such as Figure 9 and Figure 10 As shown, when the cabinet door 100 moves relative to the cabinet body 500 from the position of closed storage space to the position of open storage space, the first pivot fixing seat 312 is fixed to the cabinet door 100 along with the hinge seat. During the rotation of the cabinet door 100, the first slider 322 will move along the first guide rail in the first direction. Correspondingly, the first slider 322 will pull the second slider 323 along the second guide rail in the second direction through the first connector 3241. Since the base 321 is fixedly connected to the cabinet door 100 and the second slider 323 is fixedly connected to the cabinet door 200, the cabinet door 200 will move relative to the cabinet door 100 in the second direction. The first direction and the second direction are opposite, and both the first direction and the second direction are parallel to the width direction of the cabinet door 100.

[0114] Correspondingly, when the cabinet door 100 moves relative to the cabinet body 500 from the position of opening the storage space to the position of closing the storage space, during the rotation of the cabinet door 100, the first slider 322 will move on the first guide rail in a direction opposite to the first direction. Correspondingly, the first slider 322 will pull the second slider 323 on the second guide rail in a direction opposite to the second direction through the second connector 3242. At this time, the cabinet door 200 will move relative to the cabinet door 100 in a direction opposite to the second direction.

[0115] In another embodiment of the invention, such as Figure 11 and Figure 12 As shown, the sliding door mechanism 300 includes: a base 321, a first slider 322, a second slider 323, and a transmission member 328. A first guide rail is formed on one side of the base 321, and a second guide rail is formed on the other side. The first slider 322 is slidably mounted on the first guide rail, and the second slider 323 is slidably mounted on the second guide rail. The transmission member 328 is connected at both ends to the first slider 322 and the second slider 323, respectively. When the first slider 322 moves on the first guide rail, the first slider 322 drives the second slider 323 to move in the opposite direction on the second guide rail via a connecting member 324.

[0116] The base 321 can be fixed to the door 100 using bolts or similar structures. For example, a first receiving plate 326 and a second receiving plate 327 are respectively provided on both sides of the base 321 along its length, and through holes are provided on both the first receiving plate 326 and the second receiving plate 327. During installation, external bolt holes can pass through the through holes on the first receiving plate 326 and the second receiving plate 327 and connect to the door 100, thereby fixing the base 321 to the door 100.

[0117] In some embodiments, the traction assembly includes a first link and a second link. A first end of the first link is rotatably disposed on the front side of the housing.

[0118] The first end of the first connecting rod is rotatably disposed within the installation area. For example, the first end of the first connecting rod is mounted within the installation area via a rotating shaft fixing seat. The first end of the second connecting rod is rotatably connected to the second end of the first connecting rod; the second end of the second connecting rod is rotatably disposed on the door 100 and is connected to the first slider 322 via a gear disposed at the second end of the second connecting rod.

[0119] Understandably, 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 degrees, and the second link can rotate relative to the box door 100 degrees.

[0120] When the second end of the second link moves in a circle around the hinge axis with the door 100, the distance between the second end of the second link and the first end of the first link changes because the first end of the first link is misaligned with the hinge axis. However, the position of the second end of the second link relative to the door 100 remains unchanged. This causes the second end of the second link to rotate around the door 100 and drive the second slider 323 to move the cabinet door 200 along the width direction of the door 100.

[0121] In practical applications, during the opening of the cabinet door 100, the cabinet door 100 drives the second end of the second connecting rod to rotate relative to the hinge axis. Based on the misaligned 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, causing the second end of the second connecting rod to rotate clockwise relative to the cabinet door 100. This, in turn, controls the second slider 323 to drive the cabinet door 200 to move away from the hinge 400 along the width direction of the cabinet door 100, that is, to move to the left relative to the cabinet door 100. This avoids interference between the cabinet door 200 and the side cabinet door 200. During the closing process, the cabinet door 100 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, causing the second end of the second link to rotate counterclockwise relative to the cabinet door 100. This, in turn, controls the second slider 323 to drive the cabinet door 200 to move along the width direction of the cabinet door 100 towards the direction closer to the hinge 400, that is, to move to the right relative to the cabinet door 100. This ensures that when the cabinet door 100 is closed, the cabinet door 200 can avoid the cabinet door 200 on the side of the cabinet and reset the cabinet door 200.

[0122] In an optional embodiment, the first rotating shaft fixing seat 312 is connected to the first slider 322, and the second slider 323 is connected to the cabinet door 200. The first and second guide rails serve as tracks, and the first and second sliders 322 and 323 are sliding members adapted to and slidable along their respective guide rails. Furthermore, the sliding engagement of the first slider 322 with the first guide rail should at least include the presence of ball bearings between the first slider 322 and the first guide rail, and the sliding engagement of the second slider 323 with the second guide rail should at least include the presence of ball bearings between the second slider 323 and the second guide rail.

[0123] like Figure 11 As shown, the transmission component 328 includes a first rack 3281, a second rack 3282, and a gear 3283. The first rack 3281 is disposed on the first slider 322, and the second rack 3282 is disposed on the second slider 323. The gear 3283 is rotatably disposed on the base 321 and meshes with the first rack 3281 and the second rack 3282.

[0124] In this embodiment, when the first slider 322 slides along the first guide rail, the first rack 3281 slides along with the first slider 322. The first rack 3281 meshes with the gear 3283. When the first rack 3281 slides, it drives the gear 3283 to rotate. The second rack 3282 and the first rack 3281 mesh with the two sides of the gear 3283 respectively. When the gear 3283 rotates, it can drive the second rack 3282 to slide in the opposite direction relative to the first rack 3281, thereby driving the second slider 323 to slide in the opposite direction relative to the first slider 322. The structure is simple, convenient and practical.

[0125] like Figure 11 As shown, the transmission component 328 also includes a pin, which is disposed on the base 321, and the gear 3283 is rotatably disposed on the pin.

[0126] In this embodiment, a pin is disposed on the base 321 to accommodate a gear 3283. The gear 3283 is rotatably disposed on the pin and can rotate around the pin to transmit power between the first rack 3281 and the second rack 3282, so that the first rack 3281 and the second rack 3282 slide in opposite directions, and the first slider 322 and the second slider 323 can slide in opposite directions.

[0127] In addition, as described above, this embodiment also provides a refrigeration device, which includes a cabinet 500 and a door device as described in the above embodiment. The cabinet 500 forms a storage space, and the door 100 is rotatably connected to the cabinet 500 via a hinge 400, which is suitable for opening or closing the storage space of the cabinet 500.

[0128] Finally, it should be noted that the terms "parallel" and "perpendicular" in the embodiments of this invention should not be strictly limited to a geometric sense. At least manufacturing and installation errors should be considered. For example, an error of ±10° should be within the protection range of the embodiments of this invention.
