[0036] like Figure 2 As shown, the door device in this embodiment of the present 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 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 to each other. The traction component 310 is at least disposed on the bottom wall 501 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.

[0037] 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.

[0038] 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.

[0039] In this embodiment, the door 100 in the door device is rotatably mounted on the cabinet 500 of the refrigeration equipment via a 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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 2As 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] It is understood that the refrigeration equipment includes the door assembly and the cabinet 500.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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 via multiple hinges 400. Specifically, the cabinet door 100 located at the bottom is rotatably connected to the cabinet body 500 via a first hinge 410 disposed on the lower crossbeam of the cabinet body 500, and a traction assembly 310 corresponding to the cabinet door 100 located at the bottom of the cabinet body 500 is disposed close to the first hinge 410.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] In a specific embodiment, such as Figure 2 As shown, the door assembly includes a first door 110 and a second door 120. The first door 110 and the second door 120 are spaced apart along the height of the box body 500. At this time, the bottom of the second door 120 can be rotatably connected to the box body 500 by means of a first hinge 410 provided on the lower crossbeam of the box body 500, and the top of the first door 110 can be rotatably connected to the box body 500 by means of a third hinge 430 provided on the top wall of the box body 500.

[0060] Correspondingly, such as Figure 3 As shown, the traction assembly 310 located on the bottom wall 501 of the box 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 second box door 120 to move relative to the width direction of the second box door 120.

[0061] Furthermore, 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 (middle crossbeam) of the housing 500, and the second hinge 420 is located between the first hinge 410 and the third hinge 430.

[0062] 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.

[0063] In practical applications, the number of second hinges 420 can be one or two. For example, when there is one second hinge 420, one of two adjacent cabinet doors 100 can be connected to the second hinge 420 and rotatably connected to the cabinet body 500 via the second hinge 420. Alternatively, 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 second hinge 420.

[0064] For example, such as Figure 2 As shown, the cabinet door 100 includes a first cabinet door 110 and a second cabinet door 120. At this time, a second hinge 420 can be disposed between the first cabinet door 110 and the second cabinet door 120. Moreover, the bottom of the first cabinet door 110 and the top of the second cabinet door 120 can be simultaneously hinged to the second hinge 420, thereby rotatably connected to the cabinet body 500.

[0065] In another embodiment, when there are two second hinges 420, the two second hinges 420 can be spaced apart along the height direction of the box 500. At this time, the two adjacent box doors 100 can be hinged to the two second hinges 420 respectively, and then rotated to the box 500 by means of their respective second hinges 420.

[0066] Furthermore, in one embodiment, such as Figure 4 As shown, the first hinge 410 includes a first hinge plate 411 and a first hinge shaft 412. The first hinge plate 411 includes a support plate 4111 and an extension plate 4112. The support plate 4111 is installed on the front side (lower crossbeam) of the housing 500. The extension plate 4112 is connected to the side of the support plate 4111 away from the front side of the housing 500. The support plate 4111 and the extension plate 4112 are set at an angle. The first hinge shaft 412 is set on the top surface of the extension plate 4112 and extends upward. The bottom of the second door 120 is hinged to the first hinge shaft 412.

[0067] Similarly, the first hinge plate 411 and the first hinge shaft 412 can also be made of metal or non-metal materials with a certain structural strength. The first hinge plate 411 includes a support plate 4111 and an extension plate 4112 that are connected to each other. The extension plate 4112 is approximately perpendicular to the support plate 4111. The two can be integrally formed by stamping or other methods. The support plate 4111 is provided with multiple mounting holes. The first hinge shaft 412 is fixedly mounted on the extension plate 4112 by welding or threaded connection or other methods.

[0068] During actual installation, multiple threaded holes can be pre-set on the front and near the bottom of the housing 500. Then, one side of the support plate 4111 in the thickness direction is attached to the front of the housing 500. Next, the mounting holes on the support plate 4111 are aligned with the threaded holes. Then, the support plate 4111 is fixed to the front of the housing 500 with bolts. The extension plate 4112 is connected to the other side of the support plate 4111 in the thickness direction and extends toward the direction of the door 100. Moreover, the first hinge shaft 412 extends upward along the height direction of the housing 500.

[0069] Based on this, when installing the door 100, a hinge hole can be set at the bottom 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.

[0070] Thus, the traction assembly 310 located on the bottom wall 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 installation area A, which is located on the bottom wall 501 of the housing 500. The 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 arranged opposite to each other, and the second side and the fourth side are arranged opposite to each other. The first side is located in the plane containing the side of the housing 500, and the second side is located in the plane containing the front of the housing 500. In the width direction of the housing 500, a first distance is left between the third side and the first side; in the thickness direction of the housing 500, a second distance is left between the fourth side and the second side.

[0071] In an optional embodiment, the first distance is greater than zero and less than or equal to 100 mm, and the second distance is greater than zero and less than or equal to 60 mm. For example, the first distance is 20 mm, 50 mm, 60 mm, 80 mm, or 100 mm, and the second distance is 20 mm, 40 mm, 50 mm, or 60 mm.

[0072] Furthermore, in one embodiment, such as Figure 5As 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 (middle crossbeam) of the housing 500. The connecting plate 4212 is connected to the side of the mounting plate 4211 away from the front of the housing 500. The connecting plate 4212 and the mounting plate 4211 are arranged 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 disposed on the first side. The bottom of the first door 110 is hinged to the second hinge shaft 422. The third hinge shaft 423 is disposed on the second side. The top of the second door 120 is hinged to the third hinge shaft 423. The second hinge 420 may be provided with at least one traction component 310. In the case of two traction components 310, one traction component 310 corresponds to the first door 110, and the other traction component 310 corresponds to the second door 120.

[0073] 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.

[0074] 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 second hinge shaft 422, and the second side is fixedly connected to the third hinge shaft 423.

[0075] 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.

[0076] 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 2As shown, multiple threaded holes are provided on the front of the housing 500 corresponding to the gap between the first door 110 and the second door 120. Then, the mounting holes on the mounting plate 4211 of the second hinge plate 421 are aligned with the threaded holes. The mounting plate 4211 is then fixed to the front of the housing 500 with bolts. At this time, the connecting plate 4212 extends toward the door 100. Meanwhile, the second hinge shaft 422 extends upward along the height direction of the housing 500, and the third hinge shaft 423 extends downward along the height direction of the housing 500.

[0077] Based on this, when installing the door 100, a hinge hole can be provided in advance at the bottom of the door 100 corresponding to the second hinge shaft 422, and a hinge hole can be provided in advance at the top of the door 100 corresponding to the third hinge shaft 423. Then, the second hinge shaft 422 and the third hinge shaft 423 can be inserted into the hinge holes of their respective door 100, thereby realizing the installation of the door 100.

[0078] Furthermore, in one embodiment, such as Figure 6 As shown, the third hinge 430 includes a third hinge plate 431 and a fourth hinge shaft 432. A portion of the third hinge plate 431 covers the top wall of the housing 500, and the remaining portion protrudes from the top wall towards the corresponding door 100. The fourth hinge shaft 432 extends downward from the portion of the third hinge plate 431 protruding from the top wall. The top of the first door 110 is hinged to the fourth hinge shaft 432. The third hinge 430 may be equipped with a traction assembly 310 corresponding to the first door 110.

[0079] For example, the third hinge plate 431 and the fourth hinge shaft 432 can be made of metal or non-metal materials with a certain structural strength. The third hinge plate 431 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 fourth hinge shaft 432 is fixedly mounted on the first protrusion by means of welding or threaded connection.

[0080] 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 third hinge plate 431 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 fourth hinge shaft 432 can extend downward along the height direction of the housing 500.

[0081] Based on this, when installing the door 100, a hinge hole can be set on the top of the door 100 corresponding to the fourth hinge 400 in advance, and then the fourth hinge shaft 432 can be inserted into the hinge hole, thereby realizing the installation of the door 100.

[0082] In another optional embodiment, there are two cabinet doors 100, which are arranged side by side. Each cabinet door 100 is provided with a corresponding cabinet door 200 and a sliding door mechanism 300. At least one of the two traction components 310 is provided on the top wall of the cabinet body 500.

[0083] It should be noted that each door 100 may be equipped with one or two sliding door mechanisms 300. When there is one sliding door mechanism 300, the corresponding traction component 310 is installed on the bottom wall 501 of the box body 500. When there are two sliding door mechanisms 300, one traction component 310 is installed on the bottom wall 501 of the box body 500, and the other traction component 310 may be installed on the bottom wall 501, side, lower crossbeam, etc. of the box body 500.

[0084] 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 bottom wall 501 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 A.

[0085] 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.

[0086] In the traction assembly 310, the first pivot fixing seat 312 is mounted on the sliding door assembly 320, and the second pivot fixing seat 313 is mounted on the bottom wall 501 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.

[0087] 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.

[0088] 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 7 and Figure 8 As shown, the sliding door assembly 320 includes: a base 321, a first sliding member, a second sliding member, and a connecting member 324. The first sliding member can be a first slider 322, and the second sliding member can be a second slider 323.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] As a specific implementation method, such as Figure 7 and Figure 8As 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.

[0093] 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.

[0094] 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.

[0095] As one implementation method, such as Figure 8 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.

[0096] Similarly, such as Figure 7 and Figure 8 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.

[0097] 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.

[0098] 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 bottom wall 501 of the housing 500 with the help of bolts or other structures.

[0099] Next, the base 321 can be fixed to the door 100 using bolts or similar structures. For example, two connecting plates 325 are provided on both sides of the base 321 along its length, each having a through hole. During installation, external bolt holes can pass through the through holes in the two connecting plates 325 and connect to the door 100, thereby fixing the base 321 to the door 100.

[0100] 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.

[0101] In practical use, such as Figure 7 and Figure 8 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 second pivot fixing seat 313 is fixed on the bottom wall 501 of the cabinet body 500. 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 connecting piece 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.

[0102] 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.

[0103] In another embodiment of this utility model, such as Figure 9 and Figure 10 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.

[0104] 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.

[0105] In some embodiments, the traction assembly includes a first link and a second link. The first end of the first link is rotatably disposed on the bottom wall 501 of the housing 500.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] like Figure 9 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.

[0112] 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.

[0113] like Figure 9 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.

[0114] 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.

[0115] 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.

[0116] Finally, it should be noted that the terms "parallel" and "perpendicular" in the embodiments of this utility model 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 utility model. Furthermore, the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
