Figures 3 to 17 The figure further describes the door device and the refrigeration equipment in this embodiment.

[0042] Specifically, if Figure 3 and Figure 4As shown, the door device in this embodiment includes: a box door 110 , a cabinet door 200 , a driven guide rail mechanism 600 and a sliding door mechanism 300 .

[0043] Among them, the box door 110 is rotatably connected to the box body 500 through the hinge 400, which is suitable for opening or closing the storage space of the box body 500; the driven guide rail mechanism 600 is configured to be arranged between the box door 110 and the cabinet door 200, and the driven guide rail mechanism 600 is used to guide the cabinet door 200 to move relative to 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 process of opening or closing the box door 110, thereby driving the cabinet door 200 to move in the width direction relative to the box door 110.

[0044] 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, etc.

[0045] It can be understood that the door device in this embodiment can be used for refrigeration equipment such as refrigerators, freezers, ice makers, etc., wherein the refrigeration equipment includes a box 500, and the box 500 forms a storage space, and the storage space can be used to place vegetables, fruits and other items that need to be refrigerated or frozen. Optionally, the box 500 of the refrigeration equipment is also provided with a refrigeration device, etc., and the refrigeration device can refrigerate the storage space.

[0046] In this embodiment, the door 110 in the door device is rotatably arranged on the cabinet 500 of the refrigeration device through the hinge 400. The door 110 can be used to realize the opening or closing of the storage space in the cabinet 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.

[0047] In order to conveniently describe the positional relationship between the various components, in this embodiment, Figure 3 As shown, 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.

[0048] 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 box body 500 in the width direction. 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.

[0049] 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 .

[0050] The door 110 is generally constructed as a flat plate structure with 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, Figure 3 As shown, the cabinet door 110 is connected to a hinge 400 on the right side of the cabinet 500 in the width direction, and the cabinet door 110 can be rotatably connected to the cabinet 500 via the hinge 400 .

[0051] Moreover, when the door 110 is in a position to close the storage space of the housing 500 , the width direction of the door 110 is parallel to the width direction of the housing 500 , and the thickness direction of the door 110 is parallel to the thickness direction of the housing 500 .

[0052] Furthermore, the cabinet door 200 can be a decorative door panel. The cabinet door 200 is constructed as a flat structure with a certain thickness. The cabinet door 200 is connected to the outer side of the cabinet door 110 that is away from the cabinet body 500. When the refrigeration equipment is placed together with the cabinet in an embedded manner or directly placed in the cabinet, when the cabinet door 110 is in a 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 that is away from the cabinet door 110 can be flush with the outer wall surface of the cabinet.

[0053] 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.

[0054] The driven guide rail mechanism 600 is arranged between the box door 110 and the cabinet door 200. In actual use, due to the gravity of the cabinet door 200 itself, the cabinet door 200 may vibrate or tilt during the movement of the cabinet door 200 relative to the box door 110. The driven guide rail mechanism 600 can provide stable support and guidance to guide the cabinet door 200 to move reliably and stably relative to the box door 110.

[0055] After the door device in the present 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.

[0056] In one embodiment, Figure 4 As shown, the door device and the cabinet 500 are configured to be arranged in the installation space formed between the first cabinet 510 and the second cabinet 520; when the cabinet door 110 is opened or closed, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the cabinet door 110 so that the cabinet door 200 avoids the side walls of the first cabinet 510 and the second cabinet 520; 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.

[0057] It can be understood that the refrigeration device includes a door device and a box body 500 .

[0058] In practice, Figure 4 As shown, when the refrigeration equipment having the door device and the cabinet 500 is placed between the adjacent first cabinet 510 and the second cabinet 520, the plurality of door assemblies in the door device can be arranged at intervals along the height direction of the cabinet 500, and the outer side of the cabinet door 110 in each door assembly is provided with a cabinet door 200, and the cabinet door 200 can move relative to the cabinet door 110 along the width direction of the cabinet door 110. Optionally, when the cabinet door 110 is in a state of closing the storage space of the cabinet 500, the outer wall surface of the cabinet door 200 that is away from the cabinet door 110 can be flush with the outer wall surfaces of the first cabinet 510 and the second cabinet 520, and the outer wall surfaces of the first cabinet 510 and the second cabinet 520 and the outer wall surface of the cabinet door 200 that is away from the cabinet door 110 are in the same direction in the thickness direction of the cabinet 500.

[0059] 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 .

[0060] Alternatively, after the refrigeration device is placed in the cabinet, a cabinet door 200 may be provided on the outside of the cabinet door 110 of each door assembly, and the cabinet door 200 may be movable relative to the cabinet door 110. Optionally, when the cabinet door 110 is in a state of closing the storage space of the cabinet 500, the outer wall surface of the cabinet door 200 that is away from the cabinet door 110 may be flush with the outer wall surface of the cabinet, and the outer wall surface of the cabinet and the outer wall surface of the cabinet door 200 that is away from the cabinet door 110 are in the same direction in the thickness direction of the cabinet 500.

[0061] 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.

[0062] Furthermore, in the sliding door mechanism 300 of this embodiment, as Fig.13 and Fig.15 As shown, the sliding door mechanism 300 includes a traction assembly 310 and a sliding door assembly 320 connected to each other. The traction assembly 310 can be arranged on the hinge 400, and the sliding door assembly 320 can be arranged on the box door 110. The sliding door assembly 320 can also be connected to the cabinet door 200. When the box door 110 rotates relative to the box 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 box door 110.

[0063] For example, since the hinge 400 is fixedly connected to the box body 500, during the rotation of the 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.

[0064] Therefore, after the door body device in the present embodiment is installed on the cabinet 500 of the refrigeration equipment, a plurality of door body assemblies can be arranged at intervals along the height direction of the cabinet 500, and each door body assembly can correspond to at least one storage space of the cabinet 500. During the rotation of the cabinet door 110 in each door body assembly relative to the cabinet 500, the sliding door assembly 320 can move the cabinet door 200 relative to the cabinet door 110 under the drive of the traction assembly 310. Therefore, 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 avoid interference with the cabinet during the process of opening the cabinet door 110.

[0065] Furthermore, in one embodiment, there are multiple box doors 110, each box door 110 corresponds to at least one storage space; each box 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 box door 110 is provided with a traction assembly 310.

[0066] It can be understood that, according to different refrigeration requirements, different numbers of storage spaces can be set in the cabinet 500 of different refrigeration equipment. 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 storage space position. For example, one cabinet door 110 can correspond to one storage space position, or it can correspond to two or more storage space positions.

[0067] Moreover, each box door 110 can be rotatably connected to the box body 500 through a plurality of hinges 400. For example, each box door 110 can be rotatably connected to the box body 500 through two hinges 400. In addition, a cabinet door 200 is also provided on the outside of each box door 110. In order to avoid interference between the cabinet door 200 and the external cabinet during the process of opening the box door 110, a sliding door mechanism 300 is correspondingly provided between each box door 110 and the cabinet door 200 provided on the outside thereof, and the traction assembly 310 in the sliding door mechanism 300 is provided on at least one hinge 400 connecting the box door 110 and the box body 500. For example, when a sliding door mechanism 300 is provided between the box door 110 and the cabinet door 200 on the outside thereof, the traction assembly 310 in the sliding door mechanism 300 can be provided on one hinge 400 connecting the box door 110 and the box body 500.

The second hinge plate 421 includes a support plate 4211 and an extension plate 4212 that are connected to each other. The extension plate 4212 is roughly perpendicular to the support plate 4211. The two can be integrally formed by stamping or the like. The support plate 4211 is provided with a plurality of mounting holes. The second hinge shaft 422 is fixed on the extension plate 4212 by welding or threaded connection.

[0088] During actual installation, multiple threaded holes can be set in advance on the front side of the box 500 and near the bottom, and then one side of the support plate 4211 in the thickness direction is attached to the front side 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 side of the box 500 with the help of bolts.

[0100] Therefore, through the above arrangement, the first door 111 and the second door 112 can be rotatably connected to the box body 500.

[0101] 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 .

[0102] Furthermore, in the present 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 .

[0103] Exemplarily, 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. At this time, the third hinge 430 can be provided with only one traction assembly 310.

[0105] 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.

[0106] Further, in one embodiment, the third hinge 430 is provided with two traction components 310 , one traction component 310 is provided at one of the mounting plate 4311 and the connecting plate 4312 , and the other traction component 310 is provided at one of the third hinge shaft 432 and the fourth hinge shaft 433 .

[0107] Exemplarily, the first door 111 and the second door 112 corresponding to the third hinge 430 are simultaneously connected to the sliding door mechanism 300, and the two sliding door mechanisms 300 each include a traction assembly 310, wherein one traction assembly 310 is connected to the mounting plate 4311 or the 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 part of the structure of one traction assembly 310 is connected to the mounting plate 4311, and a part of the structure of the other traction assembly 310 is connected to the fourth hinge shaft 433.

[0108] For example, Fig.10 As shown, the first door 111 and the second door 112 are respectively connected to a sliding door mechanism 300 , and the traction components 310 in the two sliding door mechanisms 300 can be fixedly connected to the mounting plate 4311 via the same bolt.

[0109] Furthermore, in some embodiments, Fig.11 As shown, the driven guide rail mechanism 600 includes: a slide rail 610 and a moving part.

[0110] The slide rail 610 is configured to be disposed on the cabinet door 110 and extend along the width direction of the cabinet door 110 ; the moving part is movably disposed on the slide rail 610 along the width direction of the cabinet door 110 , and the moving part is configured to be connected to the cabinet door 200 .

[0111] For example, the slide rail 610 can be extended along the width direction of the cabinet door 110 and arranged on the cabinet door 110, and the moving member can be slidably arranged in the slide rail 610. By means of the guiding and supporting function of the slide rail 610, the moving member can stably and reliably move along the width direction of the cabinet door 110, and the moving member is fixedly connected to the cabinet door 200. Therefore, based on the high rigidity of the slide rail 610, the moving member can drive the cabinet door 200 to move along the width direction of the cabinet door 110 with a high straightness.

[0112] Optionally, the moving part and the cabinet door 200 may be connected in a detachable manner, for example, the moving part and the cabinet door 200 may be connected by fasteners, by a snap-on connection, or by a magnetic connection. In actual installation, the detachable connection improves the versatility and adaptability of the sliding door mechanism 300, simplifies the manufacturing and assembly process, and reduces the production cost.

[0113] In some embodiments, there may be multiple driven guide rail mechanisms 600 , and the multiple driven guide rail mechanisms 600 may be arranged at intervals along the width direction of the box door 110 , or may be arranged at intervals along the height direction of the box door 110 .

[0114] For example, Figure 3 As shown, the top and bottom of the first door 111 are respectively provided with driven rail mechanisms 600, and the top and bottom of the first door 111 can be connected to the cabinet door 200 through the driven rail mechanisms 600. For another example, the top and bottom of the second door 112 are also respectively provided with driven rail mechanisms 600, and the top and bottom of the second door 112 can also be connected to the cabinet door 200 through the driven rail mechanisms 600.

[0115] Further, in one embodiment, if Fig.11 As shown, the moving part includes: a sliding part 620 and a hanging part 630. The sliding part 620 is movably arranged on the slide rail 610 along the width direction of the cabinet door 110; the hanging part 630 is configured to be connected with the cabinet door 200 and hung on the sliding part 620.

[0116] Exemplarily, the sliding member 620 is disposed in the slide rail 610, and the sliding member 620 can move in the slide rail 610 along the width direction of the cabinet door 110, and the hanging member 630 can be connected between the sliding member 620 and the cabinet door 200, which can ensure that the sliding member 620 and the cabinet door 200 remain fixed, so that when the sliding member 620 moves in the slide rail 610, the cabinet door 200 can move synchronously with the sliding member 620 to achieve the movement of the cabinet door 200 relative to the cabinet door 110. Moreover, the hanging member 630 is configured to allow the sliding member 620 to be detachably connected to the cabinet door 200.

[0117] In a specific embodiment, Fig.12 As shown, the sliding member 620 includes a sliding body 621 and an adapter seat 622, the sliding body 621 and the adapter seat 622 are fixedly connected, a support frame is provided on the slide rail 610, a round hole is provided on the support frame, a ball is installed in the round hole, and the sliding body 621 realizes rolling contact with the slide rail 610 via the ball. A first slot is provided on the adapter seat 622, and the hanging member 630 can be hung in the first slot.

[0118] The relative movement between the sliding body 621 and the slide rail 610 of this embodiment is rolling friction, which can reduce friction and improve the movement efficiency of the moving parts. This design can accurately control the movement trajectory and distance of the cabinet door 200, avoid interference with the side walls of the cabinet, and achieve smooth opening and closing of the cabinet door 110.

[0119] Further, in one embodiment, if Fig.12 As shown, the hanging member 630 includes: a fixing seat 631 and a hanging member 632. The fixing seat 631 is configured to be connected to the cabinet door 200; the hanging member 632 is adjustably arranged on the fixing seat 631 along the vertical direction or the horizontal direction, and the hanging member 632 is hung on the sliding member 620.

[0120] Exemplarily, slight adjustments can be made between the hanger 632 and the fixing seat 631 in the vertical or horizontal direction, so that the position deviation between the cabinet door 200 and the box door 110 can be adjusted by adjusting the relative position between the hanger 632 and the fixing seat 631, so that the box door 110 and the cabinet door 200 can correct slight deviations in installation or manufacturing through fine-tuning, thereby ensuring the aesthetic installation of the box door 110 and the cabinet door 200.

[0121] In actual use, the fixing base 631 can be fixedly connected to the cabinet door 200 via structures such as screws, and a mounting groove is formed on the fixing base 631 for accommodating the hanger 632; the hanger 632 can be slidably arranged in the mounting groove, and a first card joint is formed on the hanger 632. By adjusting the position of the hanger 632 in the mounting groove, the relative position of the cabinet door 200 and the box door 110 can be adjusted.

[0122] It can be understood that, through the adjustable design, the user can adjust the position of the cabinet door 200 according to actual needs to meet the needs of different usage scenarios.

[0123] Further, the first clamping joint is roughly constructed as a U-shaped hook, with its opening facing downward, and the first clamping joint can pass through and be clamped into the first clamping slot. The hanger 632 is provided with a first rectangular hole extending vertically, the fixed seat 631 is provided with two mounting holes and a mounting slot extending left and right between the two mounting holes, and the side wall of the mounting slot is provided with a second rectangular hole extending laterally, and the hanger 632 can slide in the mounting slot. By controlling the position of the hanger 632 in the mounting slot, the hanger 632 can be moved up and down relative to the fixed seat 631. A screw can be set to pass through the first rectangular hole on the mounting slot and the second rectangular hole on the hanger 632, so as to form a hanger 632 that can be adjusted in both the up, down, left and right directions. And through the relative position of the mounting hole of the fixed seat 631 and the cabinet door 200, the position of the fixed seat 631 and the cabinet door 200 can be adjusted in the up, down, left and right directions.

[0124] During actual installation, the hanging member 630 and the cabinet door 200 can be installed in the following manner: First, the hanging piece 632 is inserted into the installation slot of the fixing seat 631, and screws are used to pass through the second rectangular hole, the first rectangular hole and the cabinet door 200 to connect the fixing seat 631 to the cabinet door 200 as a whole. The first card connector on the connected hanging piece 632 is hung in the first card slot to complete the connection between the hanging piece 632 and the adapter 622; then, by observing the positional relationship between the cabinet door 200 and the box door 110, whether there is a deviation is detected, wherein if there is a deviation, the position can be adjusted through the first rectangular hole and the second rectangular hole, and when the deviation is large, the screws can be removed, the hanging piece 630 is separated from the cabinet door 200, and the position of the hanging piece 630 is adjusted until the installation position meets the requirements. If the positional relationship meets the requirements and does not need to be adjusted, screws are used to pass through the installation holes on both sides of the fixing seat 631 and the cabinet door 200 to further fix the cabinet door 200 and the fixing seat 631 to keep its position stable.

[0125] The above method can not only fine-tune the position of the fixing seat 631, but also ensure that all fixations are firm, thereby ensuring that the positional relationship between the cabinet door 200 and the box door 110 is accurate.

[0126] Further, in one embodiment, if Fig.13 and Fig.15As shown, in order to ensure that the traction assembly 310 can drive the sliding door assembly 320 to move, the hinge 400 includes a hinge plate and a hinge shaft arranged on the hinge plate, the hinge plate is arranged on the box body 500, and the cabinet door 110 is rotatably arranged on the box body 500 through the hinge shaft; the traction assembly 310 includes a traction rod 311, a first rotating shaft fixing seat 312 and a second rotating shaft fixing seat 313; the first rotating shaft fixing seat 312 is connected to the sliding door assembly 320, and the second rotating shaft fixing seat 313 is connected to the hinge 400 plate, one end of the traction rod 311 is rotatably connected to the first rotating shaft fixing seat 312, and the other end of the traction rod 311 is rotatably connected to the second rotating shaft fixing seat 313; in the process of opening or closing the cabinet 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 cabinet door 110.

[0127] For example, the hinge 400 may include a hinge plate and a hinge shaft, and the hinge shaft is fixed to the hinge plate by welding or other methods. During actual installation, the hinge plate may be fixed to the box body 500 by means of bolts or other structures, and the box door 110 may be provided with threaded holes in advance. After the hinge plate is fixed to the box body 500, the hinge shaft can be inserted into the hinge hole of the box door 110, thereby realizing the rotation connection of the box door 110 relative to the box body 500.

[0128] In the traction assembly 310 , the first rotation shaft fixing seat 312 is arranged on the sliding door assembly 320 , the second rotation shaft fixing seat 313 is arranged 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 .

[0129] 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.

[0130] Further, in one embodiment, if Fig.13 and Fig.14 As shown, the sliding door assembly 320 includes: a base 321 , a first sliding block 322 , a second sliding block 323 and a transmission member 330 .

[0131] The base 321 has a first guide rail 3211 formed on one side and a second guide rail 3212 formed on the other side; the first slider 322 is slidably disposed 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 disposed on the second guide rail 3212 and is connected to the cabinet door 200; the two ends of the transmission member 330 are respectively transmission-connected to the first slider 322 and the second slider 323. When the cabinet door 110 is opened or closed, 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 transmission member 330.

[0132] Exemplarily, in this embodiment, the sliding door mechanism 300 can be arranged on the box door 110, one of the first slider 322 and the second slider 323 is transmission-connected to the box body 500, and the other is slidingly connected to the cabinet door 200 arranged on the outside of the box door 110. When the box door 110 rotates, the two sliders can slide relative to each other to drive the cabinet door 200 to slide relative to the box door 110, so that the cabinet door 200 can avoid obstacles on both sides during the process of turning the box door 110 on and off.

[0133] Specifically, taking the first slider 322 connected to the door 110 and the second slider 323 connected to the door panel as an example, the base 321 of this embodiment can be set on the door 110. The two ends of the transmission member 330 are respectively connected to the first slider 322 and the second slider 323, so that the first slider 322 can drive the second slider 323 to move synchronously, thereby driving the cabinet door 200 to slide relative to the door 110.

[0134] By properly setting the transmission direction of the transmission member 330 , the first slider 322 and the second slider 323 move in opposite directions during movement, so as to drive the door panel to avoid obstacles.

[0135] It is understandable that the first slider 322 may also be connected to the cabinet door 200, and correspondingly, the second slider 323 is connected to the box body 500. The working process is the same as that of the above embodiment and will not be repeated here.

[0136] In order to ensure that the first slider 322 can drive the second slider 323 to move in the opposite direction on the base 321, as shown in FIG. Fig.13 As shown, the transmission member 330 includes: a first rack 331 , a second rack 332 and a gear 333 .

[0137] The first rack 331 is disposed on the first slider 322 ; the second rack 332 is disposed on the second slider 323 ; the gear 333 is rotatably disposed on the base 321 and meshes with the first rack 331 and the second rack 332 .

[0138] In this embodiment, the first rack 331 is extended along the length direction of the first guide rail 3211 and is arranged on the first slider 322, the second rack 332 is extended along the length direction of the second guide rail 3212 and is arranged on the second slider 323, the gear 333 is rotatably arranged on the base 321 and is located between the first rack 331 and the second rack 332, and the first rack 331 and the second rack 332 are respectively engaged with the gear 333 from both sides of the gear 333. When the first slider 322 drives the first rack 331 to move, the first rack 331 can drive the gear 333 to rotate, and at this time, the gear 333 can drive the second rack 332 to move in the opposite direction relative to the first rack 331, so that the second slider 323 can slide in the opposite direction relative to the first slider 322.

[0139] During actual installation, after the hinge plate is fixedly mounted on the box body 500, the second shaft fixing seat 313 can be fixed on the hinge plate by means of bolts or other structures. For example, a through hole is provided in the second shaft fixing seat 313, and during installation, an external bolt can pass through the through hole and connect to the hinge plate, thereby fixing the second shaft fixing seat 313 on the hinge plate.

[0140] Then, the base 321 can be fixed to the door 110 by means of bolts or other structures. For example, two sides of the base 321 in the length direction are respectively provided with joint plates 325, and through holes are respectively provided on the two joint plates 325. During installation, external bolts can be passed through the through holes on the two joint plates 325 and connected to the door 110, so that the base 321 is fixed to the door 110.

[0141] 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.

[0142] In actual use, Fig.13 and Fig.14 As shown, when the door 110 moves from the position of closing the storage space to the position of opening the storage space relative to the box body 500, the first rotating shaft fixing seat 312 is fixed on the door 110 following the hinge seat. During the rotation of the door 110, the first slider 322 will move along the A direction on the first guide rail 3211. At the same time, the first rack 331 will drive the gear 333 to rotate in the clockwise direction, and the gear 333 will drive the second rack 332 to move along the B direction. Correspondingly, the second slider 323 will also move along the B direction. 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 B direction. The A direction is opposite to the B direction, and both the A direction and the B direction are parallel to the width direction of the door 110.

[0143] 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. At the same time, the first rack 331 will drive the gear 333 to rotate in a counterclockwise direction, and the gear 333 will drive the second rack 332 to move in a direction opposite to direction B. Accordingly, the second slider 323 will also move in a direction opposite to direction B.

[0144] Furthermore, in another specific implementation, as Figures 15 to 17 As shown, 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.

[0145] 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, disposed on a hinge plate of the hinge 400 .

[0146] The first end of the first connecting rod is rotatably disposed in the installation area, for example, the first end of the first connecting rod is mounted in 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 110, and is meshed with the toothed portion on the first slider 322 via a gear disposed on the second end of the second connecting rod.

[0147] 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.

[0148] 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 offset from 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.

[0149] 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 side 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.

[0150] In an optional embodiment, the first rotating shaft fixing seat 312 is connected to the first sliding block 322 , and the cabinet door 200 can be fixedly connected to the second sliding block 323 .

[0151] Accordingly, the traction rod 311 may be constructed as an arc-shaped rod, one end of the traction rod 311 is rotatably connected to the first rotation shaft fixing seat 312 via a first rotation shaft, and the other end of the traction rod 311 is rotatably connected to the second rotation shaft fixing seat 313 via a second rotation shaft.

[0152] As a way to achieve this, Fig.16 and Fig.17 As shown, the first rotating shaft fixing seat 312 is provided with a first clamping portion, and the first clamping portion includes two clamping plates arranged side by side and spaced apart, and the two clamping plates are respectively provided with pin holes, and the first rotating shaft is inserted into the two pin holes at the same time, and 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, thereby, 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 sliding block 322 by welding or the like.

[0153] Similarly, if Fig.15 and Fig.17As shown, 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 other end of the traction rod 311 can be placed between the two clamping plates, and the end of the traction rod 311 can be rotatably connected to the second rotating shaft, thereby, the traction rod 311 can be rotatably connected to the second rotating shaft fixing seat 313.

[0154] The first slider 322 and the second slider 323 are connected to each other through 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.

[0155] During actual installation, after the hinge plate is fixedly mounted on the box body 500, the second shaft fixing seat 313 can be fixed on the hinge plate by means of bolts or other structures. For example, a through hole is provided in the second shaft fixing seat 313, and during installation, an external bolt can pass through the through hole and connect to the hinge plate, thereby fixing the second shaft fixing seat 313 on the hinge plate.

[0156] Then, the base 321 can be fixed to the box door 110 by means of bolts and other structures. For example, a first receiving plate 326 and a second receiving plate 327 are respectively provided on both sides of the length direction of the base 321, and through holes are respectively provided on the first receiving plate 326 and the second receiving plate 327. During installation, external bolts can be passed through the through holes on the first receiving plate 326 and the second receiving plate 327 and connected to the box door 110, so as to fix the base 321 to the box door 110.

[0157] 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.

[0158] In actual use, Fig.15 and Fig.16 As shown, when the door 110 moves relative to the box body 500 from the position of closing the storage space toward the position of opening the storage space, the first rotating shaft fixing seat 312 is fixed on the door 110 following the hinge seat. During the rotation of the door 110, the first slider 322 will move along the C direction on the first guide rail 3211. Correspondingly, the first slider 322 will pull the second slider 323 to move along the D direction on the second guide rail 3212 through the connecting member 324. Since the base 321 is fixedly connected to the door 110 and the second slider 323 is fixedly connected to the cabinet door 200, 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.

[0159] Correspondingly, when the door 110 moves from the position of opening the storage space to the position of closing the storage space relative to the box body 500, 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. Correspondingly, 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.

[0160] Among them, the first guide rail and the second guide rail are used as a kind of track, and the first slider 322 and the second slider 323 are sliding parts that are adapted to the corresponding guide rails and can slide along the corresponding guide rails; in addition, the sliding cooperation between the first slider 322 and the first guide rail should at least include the situation that a ball is set between the first slider 322 and the first guide rail, and the sliding cooperation between the second slider 323 and the second guide rail should at least include the situation that a ball is set between the second slider 323 and the second guide rail.

[0161] Furthermore, in one embodiment, in order to ensure that the first slider 322 can effectively drive the second slider 323 to move in the opposite direction, Figures 15 to 17 As shown, the connecting member 324 includes: a first connecting member 3241 and a second connecting member 3242 .

[0162] 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 other end of the base 321, and its two ends are respectively connected to the other ends of the first slider 322 and the second slider 323.

[0163] 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 bypassing one end of the base 321, that is, in the length direction of the base 321, the first connecting member 3241 bypasses one end of the base 321, and its two ends extend 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.

[0164] Correspondingly, one end of the second connecting member 3242 is connected to the first slider 322, and the other end is connected to the second slider 323 after bypassing the other end of the base 321. That is, in the length direction of the base 321, the second connecting member 3242 bypasses the other end of the base 321, and its two ends are also connected to the first slider 322 and the second slider 323 respectively.

[0165] 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 annular structure.

[0166] 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 FIG. Fig.17 As shown, a first roller 328 and a 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 support the first connecting member 3241 and the second connecting member 3242 respectively.

[0167] Specifically, if Fig.17 As shown, there are two first rollers 328, and the two first rollers 328 are arranged at intervals along the width direction of the base 321. Moreover, the two first rollers 328 can be rotatably arranged on the first receiving plate 326, respectively. In order to conveniently receive the first connecting member 3241, the outer periphery of the first roller 328 can be provided with a receiving groove along its circumferential direction. Therefore, when the first connecting member 3241 is installed, the first connecting member 3241 can be placed in the receiving grooves of the two first rollers 328. Thereafter, when the first slider 322 pulls the second slider 323 with the help of the first connecting member 3241, the first connecting member 3241 can drive the two first rollers 328 to rotate.

[0168] Similarly, there are two second rollers 329, which are spaced apart along the width direction of the base 321. Moreover, the two second rollers 329 can be rotatably arranged on the second receiving plate 327, respectively. In order to conveniently receive the second connecting member 3242, the outer circumference of the second roller 329 can also be provided with a receiving groove along its circumferential direction. Therefore, when the second connecting member 3242 is installed, the second connecting member 3242 can be placed in the receiving grooves of the two second rollers 329. Thereafter, when the first slider 322 pulls the second slider 323 with the help of the second connecting member 3242, the second connecting member 3242 can drive the two second rollers 329 to rotate.

[0169] 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 parts during the movement and causing wear and consumption, and can effectively protect the first connecting member 3241 and the second connecting member 3242.

[0170] 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.

[0171] Finally, it should be noted that the parallelism and perpendicularity referred to in the embodiments of the present invention should not be strictly limited to the geometric meaning, and at least the manufacturing and installation errors should be considered. For example, the positive and negative 10° errors should be within the scope protected by the embodiments of the present invention. In addition, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
