Door components and refrigeration equipment

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese patent application No. 202411187334.4, filed on August 26, 2024, entitled "Door Assembly and Refrigeration Equipment", which is incorporated herein by reference in its entirety. Technical Field

[0003] This invention relates to the field of refrigeration equipment technology, and more particularly to a door device and refrigeration equipment. Background Technology

[0004] Currently, refrigerators are an essential appliance in almost every household. Most existing refrigerators are freestanding, and their placement requires a certain amount of space, whether in the kitchen or living room. To save space, some existing refrigerators are now built-in and placed together with cabinets.

[0005] As shown in Figure 1, to further enhance harmony and aesthetics, some built-in refrigerators 10 have a decorative panel 30 added to the outside of the refrigerator door 11, making the decorative panel 30 flush with the cabinet 20 on the side of the refrigerator 10. However, in actual use, as shown in Figure 2, the gap between the refrigerator 10 and the cabinet 20 is small. When opening the refrigerator door 11, the decorative panel 30 interferes with the cabinet 20. To avoid interference, the usual solutions are to reduce the opening angle or increase the distance between the cabinet 20 and the side of the refrigerator 10.

[0067] In one embodiment of the present invention, a door device and a refrigeration device are provided. The door device is used for the refrigeration device and includes a cabinet door, a driven guide rail mechanism, and a sliding door mechanism. When the refrigeration device is embedded in a cabinet or placed directly in a cabinet, the cabinet door is slidably provided on the outer side of the cabinet door. When the cabinet door is closed, the cabinet door is flush with the cabinet door panel, ensuring coordination and aesthetics. When the cabinet door is opened, the sliding door mechanism can drive the cabinet door to move, avoiding interference between the cabinet door and the cabinet door panel, thus improving the user experience. The door device and refrigeration device of this embodiment are further described below with reference to Figures 3 to 17.

[0068] Specifically, as shown in Figures 3 and 4, 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.

[0069] The cabinet door 110 is rotatably connected to the cabinet body 500 via a hinge 400, and is suitable for opening or closing the storage space of the cabinet body 500. The driven guide rail mechanism 600 is configured to be located between the cabinet door 110 and the cabinet door 200, and is used to guide the cabinet door 200 to move relative to the cabinet door 110. 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 located on the hinge 400, and the sliding door component 320 is located on the cabinet door 110 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 cabinet door 110, thereby causing the cabinet door 200 to move in the width direction relative to the cabinet door 110.

[0070] The thickness of the cabinet door 110 is 18-60mm, and for example, the thickness of the cabinet door 110 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.

[0071] 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.

[0072] In this embodiment, the door 110 in the door device is rotatably mounted on the cabinet 500 of the refrigeration equipment via a hinge 400. The door 110 can be used to open or close the storage space in the cabinet 500. When the door 110 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 110 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.

[0073] To facilitate the description of the positional relationship between the various components, in this embodiment, as shown in Figure 3, 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.

[0074] 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 110 is connected to the side of the box 500 in the thickness direction where the opening is provided. The box door 110 extends along the width direction of the box 500. A hinge 400 is connected to the box door 110 on one side of the box 500 in the width direction. The box door 110 can be rotatably connected to the box 500 via the hinge 400, thereby ensuring that the box door 110 can open or close the storage space of the box 500.

[0075] Furthermore, the side of the housing 500 where the door 110 is installed is the front, that is, the door 110 is installed on the front of the housing 500.

[0076] The door 110 is generally constructed as a flat plate with a certain thickness. The door 110 has mutually perpendicular height, width, and thickness directions. The height direction of the door 110 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 110 in the width direction can be rotatably connected to the box body 500 via a hinge 400. For example, as shown in Figure 3, the door 110 is connected to the right side of the box body 500 in the width direction via a hinge 400, allowing the door 110 to be rotatably connected to the box body 500.

[0077] Furthermore, when the door 110 is in the position of closing the storage space of the box 500, the width direction of the door 110 is parallel to the width direction of the box 500, and the thickness direction of the door 110 is parallel to the thickness direction of the box 500.

[0078] Cabinet door 200 can be a decorative door panel. Cabinet door 200 is constructed as a flat plate structure with a certain thickness. Cabinet door 200 is connected to the outer side of box door 110 away from the outer side of box body 500. When the refrigeration equipment is embedded in the cabinet or placed directly in the cabinet, when box door 110 is in the closed position, cabinet door 200 can be flush with the cabinet door panel. That is, the outer wall of cabinet door 200 away from box door 110 can be flush with the outer wall of the cabinet.

[0079] 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.

[0080] The driven guide rail mechanism 600 is located between the cabinet door 110 and the cabinet door 200. In actual use, due to the weight 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 cabinet door 110. The driven guide rail mechanism 600 can provide stable support and guidance, guiding the cabinet door 200 to move reliably and stably relative to the cabinet door 110.

[0081] In this embodiment, the door device is installed after 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. 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 110.

[0082] In one embodiment, as shown in FIG4, the door device and the cabinet 500 are configured to be disposed in the installation space formed between the first cabinet 510 and the second cabinet 520; during the opening or closing of the cabinet door 110, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the cabinet door 110 so that the cabinet door 200 avoids the side walls of the first cabinet 510 and the second cabinet 520.

[0083] 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 110, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the cabinet door 110 so that the cabinet door 200 avoids the side wall of the cabinet.

[0084] It is understood that the refrigeration equipment includes the door assembly and the cabinet 500.

[0085] In practice, as shown in Figure 4, when a refrigeration device with the door assembly and the cabinet 500 is placed between adjacent first cabinets 510 and second cabinets 520, multiple door components in the door assembly can be spaced apart along the height direction of the cabinet 500. Each door component has a cabinet door 200 on its outer side of the cabinet door 110, 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 the closed storage space of the cabinet 500, the outer wall surface of the cabinet door 200 facing away from the cabinet door 110 can be flush with the outer walls of the first cabinet 510 and second cabinets 520. The outer walls of the first cabinet 510 and second cabinets 520 and the outer wall surface of the cabinet door 200 facing away from the cabinet door 110 are in the same direction along the thickness direction of the cabinet 500.

[0086] At this time, as the cabinet door 110 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.

[0087] Alternatively, after the refrigeration equipment is placed in the cabinet, a cabinet door 200 can be provided on the outside of the door 110 of each door assembly, and the cabinet door 200 can move relative to the door 110. Optionally, when the door 110 is in the closed storage space of the cabinet 500, the outer wall surface of the cabinet door 200 away from the door 110 can be flush with the outer wall surface of the cabinet, and the outer wall surface of the cabinet and the outer wall surface of the cabinet door 200 away from the door 110 are in the same direction in the thickness direction of the cabinet 500.

[0088] At this time, as the cabinet door 110 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.

[0089] In the sliding door mechanism 300 of this embodiment, as shown in Figures 13 and 15, the sliding door mechanism 300 includes a traction component 310 and a sliding door component 320 connected to each other. The traction component 310 can be disposed on the hinge 400, and the sliding door component 320 can be disposed on the cabinet door 110. The sliding door component 320 can also be connected to the cabinet door 200. During the rotation of the cabinet door 110 relative to the cabinet body 500, the traction component 310 can drive the sliding door component 320 to move, thereby causing the cabinet door 200 to move relative to the cabinet door 110.

[0090] For example, since the hinge 400 is fixedly connected to the cabinet 500, during the rotation of the cabinet door 110 relative to the cabinet 500, the traction component 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.

[0091] Therefore, when the door device in this embodiment is installed on the cabinet 500 of the refrigeration equipment, multiple door components can be spaced apart along the height direction of the cabinet 500. Each door component can correspond to at least one storage space of the cabinet 500. During the rotation of the cabinet door 110 in each door component relative to the cabinet 500, the sliding door component 320 can move the cabinet door 200 relative to the cabinet door 110 under the drive of the traction component 310. 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 110.

[0092] In one embodiment, there are multiple cabinet doors 110, each cabinet door 110 corresponding to at least one storage space; each cabinet door 110 is rotatably connected to the cabinet body 500 by multiple hinges 400, and at least one of the multiple hinges 400 corresponding to each cabinet door 110 is provided with a traction component 310.

[0093] It is understandable that, depending on different refrigeration needs, the cabinet 500 of different refrigeration equipment can be equipped 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 are used for freezing. Accordingly, in order to selectively close these storage spaces, there can be multiple cabinet doors 110, and each cabinet door 110 corresponds to at least one storage space location. For example, one cabinet door 110 can correspond to one storage space location, or it can correspond to two or more storage space locations.

[0094] Furthermore, each door 110 can be rotatably connected to the cabinet body 500 via multiple hinges 400. For example, each door 110 can be rotatably connected to the cabinet body 500 via two hinges 400. In addition, a cabinet door 200 is provided on the outer side of each door 110. To avoid interference between the cabinet door 200 and the outer cabinet body during the opening of the door 110, a sliding door mechanism 300 is correspondingly provided between each door 110 and the outer cabinet door 200. The traction component 310 in the sliding door mechanism 300 is provided on at least one hinge 400 connecting the door 110 and the cabinet body 500. For example, when a sliding door mechanism 300 is provided between the door 110 and the outer cabinet door 200, the traction component 310 in the sliding door mechanism 300 can be provided on one hinge 400 connecting the door 110 and the cabinet body 500.

[0095] In some embodiments, there are two doors 110, which are arranged along the height or width direction of the enclosure 500; or

[0096] The number of cabinet doors 110 is three, and the three cabinet doors 110 are arranged along the height direction of the cabinet body 500; or...

[0097] There are four boxes 110, namely the first box door, the second box door, the third box door and the fourth box door. The first box door and the second box door are arranged side by side along the width direction of the box body 500, the third box door and the fourth box door are arranged side by side along the width direction of the box body 500, the first box door and the third box door are arranged side by side along the height direction of the box body 500, and the second box door and the fourth box door are arranged side by side along the height direction of the box body 500.

[0098] For example, in one embodiment, there are two cabinet doors 110. The two cabinet doors 110 can be spaced apart along the height direction of the cabinet body 500. The same side of the two cabinet doors 110 is rotatably connected to the cabinet body 500 via a hinge 400. In this case, the two cabinet doors 110 can open the storage space from the same side. Alternatively, the two cabinet doors 110 can also be arranged side by side along the width direction of the cabinet body 500. The two cabinet doors 110 can be arranged in a double-opening manner.

[0099] For example, in one embodiment, there are three cabinet doors 110, which are spaced apart along the height of the cabinet body 500. The same side of the three cabinet doors 110 is rotatably connected to the cabinet body 500 via hinges 400, so that the storage space can be opened from the same side.

[0100] For example, in one embodiment, there are four doors 110, namely a first door, a second door, a third door, and a fourth door. The first door and the third door are spaced apart along the height direction of the box body 500, and the same side of the two doors 110 is rotatably connected to the box body 500 via a hinge 400. The second door and the fourth door are also spaced apart along the height direction of the box body 500, and the same side of the two doors 110 is rotatably connected to the box body 500 via a hinge 400. Furthermore, the first door and the second door are arranged side by side along the width direction of the box body 500, and the two doors 110 are arranged in a double-opening manner. The third door and the fourth door are also arranged side by side along the width direction of the box body 500, and the two doors 110 are arranged in a double-opening manner.

[0101] In one embodiment, as shown in the figure, the hinge 400 includes a first hinge 410 and a second hinge 420. The first hinge 410 is disposed on the top wall of the housing 500, and the second hinge 420 is disposed on the front side of the housing 500.

[0102] For example, when there are multiple cabinet doors 110, the multiple cabinet doors 110 can be spaced apart along the height direction of the cabinet body 500. At this time, the cabinet door 110 located at the top can be rotatably connected to the cabinet body 500 via the first hinge 410, and the cabinet door 110 located at the bottom can be rotatably connected to the cabinet body 500 via the second hinge 420.

[0103] Therefore, by setting the first hinge 410 and the second hinge 420, the top and bottom doors 110 can be opened or closed respectively for their respective storage spaces.

[0104] In a specific embodiment, as shown in FIG3, the cabinet door 110 includes a first cabinet door 111 and a second cabinet door 112. The first cabinet door 111 and the second cabinet door 112 are spaced apart along the height direction of the cabinet body 500. At this time, the top of the first cabinet door 111 can be rotatably connected to the cabinet body 500 by means of the first hinge 410, and the bottom of the second cabinet door 112 can be rotatably connected to the cabinet body 500 by means of the second hinge 420.

[0105] In order to effectively realize the installation of the door 110, the hinge 400 may also include a third hinge 430, wherein the third hinge 430 is disposed on the front of the housing 500 and is located between the first hinge 410 and the second hinge 420.

[0106] For example, since multiple doors 110 are spaced apart along the height direction of the box body 500, a third hinge 430 may be provided between two adjacent doors 110, at least one of the two adjacent doors 110 can be rotatably connected to the box body 500 by means of the third hinge 430.

[0107] In practical applications, the number of third hinges 430 can be one or two. For example, when there is one third hinge 430, one of the two adjacent cabinet doors 110 can be connected to the third hinge 430 and rotatably connected to the cabinet body 500 via the third hinge 430. Alternatively, the two adjacent cabinet doors 110 can be simultaneously connected to the third hinge 430 and rotatably connected to the cabinet body 500 via the third hinge 430.

[0108] For example, as shown in Figure 3, the cabinet door 110 includes a first cabinet door 111 and a second cabinet door 112. At this time, a third hinge 430 can be set between the first cabinet door 111 and the second cabinet door 112. Moreover, the bottom of the first cabinet door 111 and the top of the second cabinet door 112 can be simultaneously hinged to the third hinge 430, thereby rotatably connected to the cabinet body 500.

[0109] In one embodiment, as shown in FIG5, the first hinge 410 includes a first hinge plate 411 and a first hinge shaft 412. A portion of the first hinge plate 411 covers the top wall of the housing 500 and the remaining portion protrudes from the top wall toward the corresponding door 110. The first hinge shaft 412 extends downward from the portion of the first hinge plate 411 that protrudes from the top wall. The top of the corresponding door 110 is hinged to the first hinge shaft 412. The traction assembly 310 is disposed on one of the first hinge plate 411 and the first hinge shaft 412.

[0110] For example, the first hinge plate 411 and the first hinge shaft 412 can be made of metal or non-metal materials with a certain structural strength. The first hinge plate 411 includes a first fitting part and a first protrusion that are connected to each other. The first fitting part is provided with a plurality of mounting holes. The first hinge shaft 412 is fixedly mounted on the first protrusion by means of welding or threaded connection.

[0111] During actual installation, multiple threaded holes can be pre-set on the top wall of the housing 500. Then, the first fitting part of the first hinge plate 411 is fitted to the top wall of the housing 500, and the mounting holes on the first fitting part correspond to 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 110, and the first hinge shaft 412 can extend downward along the height direction of the housing 500.

[0112] Based on this, when installing the door 110, a hinge hole can be set on the top of the door 110 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 110.

[0113] A sliding door mechanism 300 is connected to the box door 110 corresponding to the first hinge 410. For example, the top of the first box door 111 is connected to the sliding door mechanism 300. The traction component 310 in the sliding door mechanism 300 can be set on the first hinge plate 411 or on the first hinge shaft 412.

[0114] For example, as shown in FIG5, in one embodiment, a vertical plate 413 is provided on the first hinge plate 411, the vertical plate 413 extends downward along the thickness direction of the first hinge plate 411, and the vertical plate 413 is provided with mounting holes.

[0115] As shown in Figure 8, during actual installation, the first hinge plate 411 is fixed to the top wall of the box 500, the first box door 111 is rotatably connected to the first hinge shaft 412, and part of the structure in the traction assembly 310 can be connected to the vertical plate 413 by means of bolts.

[0116] In one embodiment, as shown in FIG6, the second hinge 420 includes a second hinge plate 421 and a second hinge shaft 422. The second hinge plate 421 includes a support plate 4211 and an extension plate 4212. The support plate 4211 is installed on the front of the housing 500, and the extension plate 4212 is connected to the side of the support plate 4211 away from the front of the housing 500. The support plate 4211 and the extension plate 4212 are arranged at an angle. The second hinge shaft 422 is disposed on the top surface of the extension plate 4212 and extends upward. The bottom of the corresponding door 110 is hinged to the second hinge shaft 422. The traction assembly 310 is disposed on one of the second hinge plate 421 and the second hinge shaft 422.

[0117] Similarly, the second hinge plate 421 and the second hinge shaft 422 can also be made of metal or non-metal materials with a certain structural strength. 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 approximately perpendicular to the support plate 4211. The two can be integrally formed by stamping or other methods. The support plate 4211 is provided with multiple mounting holes. The second hinge shaft 422 is fixedly mounted on the extension plate 4212 by welding or threaded connection or other methods.

[0118] 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 4211 in the thickness direction is attached to the front of the housing 500, and the mounting holes on the support plate 4211 are aligned with the threaded holes. The support plate 4211 is then fixed to the front of the housing 500 with bolts. The extension plate 4212 is connected to the other side of the support plate 4211 in the thickness direction and extends toward the direction of the door 110. In addition, the second hinge shaft 422 extends upward along the height direction of the housing 500.

[0119] Based on this, when installing the door 110, a hinge hole can be set at the bottom of the door 110 corresponding to the second hinge 420 in advance, and then the second hinge shaft 422 can be inserted into the hinge hole, thereby realizing the installation of the door 110.

[0120] A sliding door mechanism 300 is connected to the box door 110 corresponding to the second hinge 420. For example, the bottom of the second box door 112 is connected to the sliding door mechanism 300. The traction component 310 in the sliding door mechanism 300 can be set on the second hinge plate 421 or on the second hinge shaft 422.

[0121] As shown in Figure 9, during actual installation, the support plate 4211 is fixed on the front of the box 500 and near the bottom. The second box door 112 is rotatably connected to the second hinge shaft 422. Some structures in the traction assembly 310 can be connected to the support plate 4211 by means of bolts.

[0122] In one embodiment, as shown in FIG7, the third hinge 430 includes a third hinge plate 431, a third hinge shaft 432, and a fourth hinge shaft 433. The third hinge plate 431 includes a mounting plate 4311 and a connecting plate 4312. The mounting plate 4311 is mounted on the front of the housing 500. The connecting plate 4312 is connected to the side of the mounting plate 4311 away from the front of the housing 500. The connecting plate 4312 and the mounting plate 4311 are arranged at an angle. The connecting plate 4312 has a first side and a second side opposite to each other. The third hinge shaft 432 is disposed on the first side, and the bottom of the corresponding door 110 is hinged to the third hinge shaft 432. The fourth hinge shaft 433 is disposed on the second side, and the top of the corresponding door 110 is hinged to the fourth hinge shaft 433. The third hinge 430 is provided with at least one traction component 310.

[0123] For example, the third hinge plate 431, the third hinge shaft 432, and the fourth hinge shaft 433 can be made of metal or non-metal materials with a certain structural strength. The third hinge plate 431 includes an interconnected mounting plate 4311 and a connecting plate 4312. The connecting plate 4312 is generally perpendicular to the mounting plate 4311, and the mounting plate 4311 has multiple mounting holes. In actual manufacturing, the mounting plate 4311 and the connecting plate 4312 can be integrally formed from the same sheet metal. Then, the connecting plate 4312 can be bent relative to the mounting plate 4311 by stamping and folding.

[0124] The two sides of the connecting plate 4312 in the thickness direction are the first side and the second side, respectively. The first side is fixedly connected to the third hinge shaft 432, and the second side is fixedly connected to the fourth hinge shaft 433.

[0125] In actual manufacturing, the third hinge shaft 432 and the fourth hinge shaft 433 can be fixedly connected to the connecting plate 4312 by welding. Alternatively, the third hinge shaft 432 and the fourth hinge shaft 433 can be constructed as a single long rod-shaped component. The connecting plate 4312 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 4312 are respectively formed as the third hinge shaft 432 and the fourth hinge shaft 433.

[0126] During actual installation, as shown in Figure 10, multiple threaded holes can be pre-set on the front of the box body 500 according to the installation position of the box door 110. For example, as shown in Figure 3, multiple threaded holes are set on the front of the box body 500 corresponding to the gap between the first box door 111 and the second box door 112. Then, the mounting holes on the mounting plate 4311 of the third hinge plate 431 are aligned with the threaded holes. The mounting plate 4311 is then fixed to the front of the box body 500 with bolts. At this time, the connecting plate 4312 extends toward the box door 110. At the same time, the third hinge shaft 432 extends upward along the height direction of the box body 500, and the fourth hinge shaft 433 extends downward along the height direction of the box body 500.

[0127] Based on this, when installing the door 110, a hinge hole can be pre-set at the bottom of the door 110 corresponding to the third hinge shaft 432, and a hinge hole can be pre-set at the top of the door 110 corresponding to the fourth hinge shaft 433. Then, the third hinge shaft 432 and the fourth hinge shaft 433 can be inserted into the hinge holes of their respective door 110, thereby realizing the installation of the door 110.

[0128] In one specific embodiment, as shown in Figure 3, the box body 500 has two storage spaces spaced apart along its height. A first hinge 410 is provided at the top of the box body 500, a second hinge 420 is provided at the bottom of the box body 500, and a third hinge 430 is provided in the middle of the box body 500, approximately between the two storage spaces. The door device includes two doors 110, namely a first door 111 and a second door 112, which are spaced apart along the height of the box body 500. The first door 111 and the second door 112 correspond to the two storage spaces of the box body 500, respectively.

[0129] During installation, the top of the first door 111 is hinged to the first hinge axis 412 of the first hinge 410, the bottom of the first door 111 is hinged to the third hinge axis 432 of the third hinge 430, the top of the second door 112 is hinged to the fourth hinge axis 433 of the third hinge 430, and the bottom of the second door 112 is hinged to the second hinge axis 422 of the second hinge 420.

[0130] Therefore, through the above-described configuration, the first door 111 and the second door 112 can be rotatably connected to the box body 500.

[0131] In addition, the third hinge 430 may be provided with at least one traction component 310. For example, the third hinge 430 may be provided with only one traction component 310, which may be connected to the third hinge plate 431, the third hinge shaft 432 or the fourth hinge shaft 433.

[0132] In this embodiment, the third hinge 430 is provided with a traction component 310, which is disposed in one of the mounting plate 4311, the connecting plate 4312, the third hinge shaft 432 and the fourth hinge shaft 433.

[0133] For example, a sliding door mechanism 300 is connected to the first door 111 or the second door 112 corresponding to the third hinge 430. In the sliding door mechanism 300, the traction component 310 can be connected to the mounting plate 4311, the connecting plate 4312, the third hinge shaft 432, or the fourth hinge shaft 433. In this case, the third hinge 430 may only have one traction component 310.

[0134] In one embodiment, the third hinge 430 is provided with two traction components 310, both of which are disposed on one of the mounting plate 4311 and the connecting plate 4312, or respectively disposed on the third hinge shaft 432 and the fourth hinge shaft 433.

[0135] For example, the first door 111 and the second door 112 corresponding to the third hinge 430 are simultaneously connected to a sliding door mechanism 300. 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. Alternatively, a portion of the structure of the two traction components 310 can be connected to the third hinge shaft 432 and the fourth hinge shaft 433, respectively.

[0136] In one embodiment, the third hinge 430 is provided with two traction components 310, one traction component 310 being provided on one of the mounting plate 4311 and the connecting plate 4312, and the other traction component 310 being provided on one of the third hinge shaft 432 and the fourth hinge shaft 433.

[0137] For example, the first door 111 and the second door 112 corresponding to the third hinge 430 are simultaneously connected to sliding door mechanisms 300. Both sliding door mechanisms 300 include traction components 310. One traction component 310 is connected to the mounting plate 4311 or the connecting plate 4312, and the other traction component 310 is connected to the third hinge shaft 432 or the fourth hinge shaft 433. For example, a portion of the structure of one traction component 310 is connected to the mounting plate 4311, and a portion of the structure of the other traction component 310 is connected to the fourth hinge shaft 433.

[0138] For example, as shown in Figure 10, the first door 111 and the second door 112 are respectively connected to sliding door mechanisms 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.

[0139] In some embodiments, as shown in FIG11, the driven guide mechanism 600 includes a slide rail 610 and a moving member.

[0140] The slide rail 610 is configured to be located on the cabinet door 110 and extend along the width direction of the cabinet door 110; the moving part is movably located on the slide rail 610 along the width direction of the cabinet door 110 and is configured to be connected to the cabinet door 200.

[0141] For example, the slide rail 610 can extend along the width direction of the cabinet door 110 and be disposed on the cabinet door 110. The moving part is slidably disposed in the slide rail 610. Utilizing the guiding and supporting function of the slide rail 610, the moving part can move stably and reliably along the width direction of the cabinet door 110, and the moving part is fixedly connected to the cabinet door 200. Thus, based on the high rigidity of the slide rail 610, the moving part can drive the cabinet door 200 to move along the width direction of the cabinet door 110 with a high degree of straightness.

[0142] Optionally, the moving parts and the cabinet door 200 can be detachably connected. For example, the moving parts and the cabinet door 200 can be connected by fasteners, by snap-fit, or by magnetic connection. In actual installation, the detachable connection method improves the versatility and adaptability of the sliding door mechanism 300, simplifies the manufacturing and assembly process, and reduces production costs.

[0143] In some embodiments, the number of driven guide rail mechanisms 600 can be multiple, and these multiple driven guide rail mechanisms 600 can be spaced apart along the width direction of the door 110 or spaced apart along the height direction of the door 110.

[0144] For example, as shown in Figure 3, the top and bottom of the first door 111 are respectively provided with driven guide rail mechanisms 600, and the top and bottom of the first door 111 can be connected to the cabinet door 200 through the driven guide rail mechanisms 600. As another example, the top and bottom of the second door 112 are also respectively provided with driven guide 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 guide rail mechanisms 600.

[0145] In one embodiment, as shown in FIG11, the moving component includes a slider 620 and a hook 630. The slider 620 is movably disposed on the slide rail 610 along the width direction of the cabinet door 110; the hook 630 is configured to connect to the cabinet door 200 and is hung on the slider 620.

[0146] For example, a slider 620 is disposed in a slide rail 610, and the slider 620 is movable in the slide rail 610 along the width direction of the cabinet door 110. A hook 630 is connected between the slider 620 and the cabinet door 200, which ensures that the slider 620 and the cabinet door 200 remain fixed, thereby ensuring that the cabinet door 200 can move synchronously with the slider 620 when the slider 620 moves in the slide rail 610, so as to realize the movement of the cabinet door 200 relative to the cabinet door 110. Moreover, the hook 630 is configured to allow a detachable connection between the slider 620 and the cabinet door 200.

[0147] In one specific embodiment, as shown in FIG12, the slider 620 includes a slider body 621 and an adapter 622, which are fixedly connected. A support frame is provided on the slide rail 610, and a circular hole is provided on the support frame. A ball bearing is installed in the circular hole, and the slider body 621 makes rolling contact with the slide rail 610 through the ball bearing. The adapter 622 is provided with a first slot, and the hanger 630 can be hung in the first slot.

[0148] In this embodiment, the relative movement between the sliding body 621 and the slide rail 610 is rolling friction, which can reduce friction and improve the movement efficiency of the moving parts. This design can precisely control the movement trajectory and distance of the cabinet door 200, avoid interference with the side wall of the cabinet, and realize the smooth opening and closing of the cabinet door 110.

[0149] In one embodiment, as shown in FIG12, the mounting bracket 630 includes a fixed base 631 and a hanging member 632. The fixed base 631 is configured to connect to the cabinet door 200; the hanging member 632 is adjustablely disposed on the fixed base 631 in a vertical or horizontal direction, and the hanging member 632 is hung on the sliding member 620.

[0150] For example, the hanger 632 and the fixing base 631 can be adjusted slightly in the vertical or horizontal direction, so that the positional 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 base 631. This allows the box door 110 and the cabinet door 200 to be finely adjusted to correct slight deviations in installation or manufacturing, thus ensuring the aesthetic appearance of the box door 110 and the cabinet door 200.

[0151] In practical use, the fixing base 631 can be fixedly connected to the cabinet door 200 by screws or other structures. The fixing base 631 has an installation groove for accommodating the hanging part 632. The hanging part 632 is slidably set in the installation groove. The hanging part 632 has a first snap joint. By adjusting the position of the hanging part 632 in the installation groove, the relative position of the cabinet door 200 and the box door 110 can be adjusted.

[0152] Understandably, the adjustable design allows users to adjust the position of the cabinet door 200 according to their actual needs, in order to meet the requirements of different usage scenarios.

[0153] The first snap-fit ​​connector is roughly U-shaped with its opening facing downwards, allowing it to snap into the first snap-fit ​​groove. The hanger 632 has a first rectangular hole extending vertically, and the mounting base 631 has two mounting holes and a mounting groove extending horizontally between the two mounting holes. The side wall of the mounting groove has a second rectangular hole extending horizontally. The hanger 632 can slide within the mounting groove. By controlling the position of the hanger 632 within the mounting groove, it can move up and down relative to the mounting base 631. Screws can be inserted through the first rectangular hole in the mounting groove and the second rectangular hole in the hanger 632, creating a hanger 632 that is adjustable in both vertical and horizontal directions. Furthermore, the relative positions of the mounting holes in the mounting base 631 and the cabinet door 200 allow for adjustment of the positions of the mounting base 631 and the cabinet door 200 in both vertical and horizontal directions.

[0154] In actual installation, the mounting bracket 630 and the cabinet door 200 can be installed in the following ways:

[0155] First, insert the hanger 632 into the mounting slot of the mounting base 631. Use screws to pass through the second rectangular hole, the first rectangular hole, and the cabinet door 200 to connect the mounting base 631 to the cabinet door 200. Then, hook the first clip on the connected hanger 632 into the first clip slot to complete the connection between the hanger 632 and the adapter 622. Next, observe the positional relationship between the cabinet door 200 and the cabinet door 110 to check for any deviation. If a deviation exists, adjust the position through the first and second rectangular holes. If the deviation is large, remove the screws to separate the hanger 630 from the cabinet door 200 and adjust the position of the hanger 630 until the installation position meets the requirements. If the positional relationship meets the requirements and no adjustment is needed, use screws to pass through the mounting holes on both sides of the mounting base 631 and the cabinet door 200 to further secure the cabinet door 200 to the mounting base 631 to maintain its stable position.

[0156] The above method not only allows for fine-tuning of the position of the fixing seat 631, but also ensures that all fixings are secure, guaranteeing the accurate positional relationship between the cabinet door 200 and the box door 110.

[0157] In one embodiment, as shown in Figures 13 and 15, to ensure that the traction assembly 310 can drive the sliding door assembly 320 to move, the hinge 400 includes a hinge plate and a hinge shaft disposed on the hinge plate. The hinge plate is disposed on the housing 500, and the cabinet door 110 is rotatably disposed on the housing 500 via 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. During the opening or closing of the cabinet door 110, 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 110.

[0158] 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 110 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 110, thereby achieving a rotatable connection between the door 110 and the housing 500.

[0159] In the traction assembly 310, the first pivot fixing seat 312 is mounted on the sliding door assembly 320, the second pivot fixing seat 313 is mounted on the hinge plate, and 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.

[0160] In actual use, when the cabinet door 110 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 110 in the width direction of the cabinet door 110.

[0161] In one embodiment, as shown in Figures 13 and 14, the sliding door assembly 320 includes: a base 321, a first slider 322, a second slider 323, and a transmission member 330.

[0162] The base 321 has a first guide rail 3211 on one side and a second guide rail 3212 on the other side. A first slider 322 is slidably mounted on the first guide rail 3211, and a first rotating shaft fixing seat 312 is connected to the first slider 322. A second slider 323 is slidably mounted on the second guide rail 3212 and connected to the cabinet door 200. The two ends of the transmission member 330 are respectively connected to the first slider 322 and the second slider 323. During the opening or closing of the cabinet door 110, the traction rod 311 drives the first slider 322 to move on the first guide rail 3211, and the first slider 322 drives the second slider 323 to move in the opposite direction on the second guide rail 3212 through the transmission member 330.

[0163] For example, in this embodiment, the sliding door mechanism 300 can be disposed on the box door 110. One of the first slider 322 and the second slider 323 is connected to the box body 500 in a transmission manner, and the other is slidably connected to the cabinet door 200 disposed 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 rotation and opening of the box door 110.

[0164] Specifically, taking the connection of the first slider 322 to the cabinet door 110 and the connection of the second slider 323 to the door panel as an example, the base 321 in this embodiment can be set on the cabinet 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 cabinet door 110.

[0165] By reasonably setting the transmission direction of the transmission component 330, the first slider 322 and the second slider 323 move in opposite directions during movement, thereby driving the door panel to avoid obstacles.

[0166] It is understood that the first slider 322 can also be connected to the cabinet door 200, and correspondingly, the second slider 323 is connected to the box body 500. Its working process is the same as that of the above embodiment, and will not be described again here.

[0167] 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 Figure 13, the transmission component 330 includes: a first rack 331, a second rack 332, and a gear 333.

[0168] The first rack 331 is disposed on the first slider 322; the second rack 332 is disposed on the second slider 323; and the gear 333 is rotatably disposed on the base 321 and meshes with the first rack 331 and the second rack 332.

[0169] In this embodiment, a first rack 331 extends along the length of a first guide rail 3211 and is disposed on a first slider 322, and a second rack 332 extends along the length of a second guide rail 3212 and is disposed on a second slider 323. A gear 333 is rotatably disposed on a base 321 and located between the first rack 331 and the second rack 332, and the first rack 331 and the second rack 332 mesh 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. At this time, the gear 333 can drive the second rack 332 to move in the opposite direction relative to the first rack 331, thereby allowing the second slider 323 to slide in the opposite direction relative to the first slider 322.

[0170] In actual installation, after the hinge plate is fixedly installed on the housing 500, the second rotating shaft fixing seat 313 can be fixed to the hinge plate using bolts or other structures. For example, the second rotating shaft fixing seat 313 is provided with a through hole. During installation, external bolts can pass through the through hole and connect to the hinge plate, thereby fixing the second rotating shaft fixing seat 313 to the hinge plate.

[0171] Next, the base 321 can be fixed to the door 110 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 bolts can pass through the through holes in the two connecting plates 325 and connect to the door 110, thereby fixing the base 321 to the door 110.

[0172] 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.

[0173] In actual use, as shown in Figures 13 and 14, when the cabinet door 110 moves relative to the cabinet body 500 from the position of closed storage space to the position of open storage space, the first rotating shaft fixing seat 312 is fixed to the cabinet door 110 along with the hinge seat. During the rotation of the cabinet door 110, the first slider 322 will move along the first guide rail 3211 in direction A. At the same time, the first rack 331 will drive the gear 333 to rotate clockwise, and the gear 333 will drive the second rack 332 to move along direction B. Correspondingly, the second slider 323 will also move along direction B. Since the base 321 is fixedly connected to the cabinet door 110 and the second slider 323 is fixedly connected to the cabinet door 200, the cabinet door 200 will move relative to the cabinet door 110 in direction B. Here, direction A is opposite to direction B, and both directions A and B are parallel to the width direction of the cabinet door 110.

[0174] 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 the opposite direction to direction A. At the same time, the first rack 331 will drive the gear 333 to rotate in the counterclockwise direction, and the gear 333 will drive the second rack 332 to move in the opposite direction to direction B. Correspondingly, the second slider 323 will also move in the opposite direction to direction B.

[0175] In another specific implementation, as shown in Figures 15 to 17, the base 321 is constructed as a plate-like structure with a certain length. The first guide rail 3211 and the second guide rail 3212 are respectively arranged on both sides of the width direction of the base 321. Moreover, the first guide rail 3211 and the second guide rail 3212 extend along the length direction of the base 321. The first slider 322 is slidably arranged on the first guide rail 3211, and the second slider 323 is slidably arranged on the second guide rail 3212.

[0176] In some embodiments, the traction assembly includes a first link and a second link. A first end of the first link is rotatably disposed on a hinge 400, for example, on a hinge plate of the hinge 400.

[0177] 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 110 and is connected to the first slider 322 via a gear disposed at the second end of the second connecting rod.

[0178] 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, and the second link can rotate relative to the box door 110.

[0179] When the second end of the second link moves in a circle around the hinge axis with the door 110, 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 110 remains unchanged. This causes the second end of the second link to rotate around the door 110 and drive the second slider 323 to move the cabinet door 200 along the width direction of the door 110.

[0180] In practical applications, during the opening of the cabinet door 110, the cabinet door 110 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 110. 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 110, that is, to move to the left relative to the cabinet door 110. This avoids interference between the cabinet door 200 and the side cabinet door 200. During the closing process, the cabinet door 110 drives the second end of the second link to rotate relative to the hinge axis. Based on the misaligned arrangement of the first end of the first link and the hinge axis, the distance between the first end of the first link and the second end of the second link decreases, causing the second end of the second link to rotate counterclockwise relative to the cabinet door 110. This, in turn, controls the second slider 323 to drive the cabinet door 200 to move along the width direction of the cabinet door 110 towards the direction closer to the hinge 400, that is, to move to the right relative to the cabinet door 110. This ensures that when the cabinet door 110 is closed, the cabinet door 200 can avoid the cabinet door 200 on the side of the cabinet and reset the cabinet door 200.

[0181] In an optional embodiment, the first pivot fixing seat 312 is connected to the first slider 322, and the cabinet door 200 can be fixedly connected to the second slider 323.

[0182] Accordingly, the traction rod 311 can be constructed as an arc-shaped 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.

[0183] As one implementation, as shown in Figures 16 and 17, the first rotating shaft fixing seat 312 is provided with a first clamping part, which includes two clamping plates arranged side by side at intervals. Each of the two clamping plates has a corresponding pin hole. The first rotating shaft is simultaneously inserted into the two pin holes. One end of the traction rod 311 can be placed between the two clamping plates, and the end of the traction rod 311 is rotatably connected to the first rotating shaft. Thus, the traction rod 311 can be rotatably connected to the first rotating shaft fixing seat 312. Furthermore, the first rotating shaft fixing seat 312 can be fixedly connected to the first slider 322 by welding or other methods.

[0184] Similarly, as shown in Figures 15 and 17, the second rotating shaft fixing seat 313 is provided with a second clamping part, which also includes two clamping plates arranged side by side at intervals. The two clamping plates are respectively provided with pin holes. The second rotating shaft is inserted into the two pin holes at the same time. The other end of the traction rod 311 can be placed between the two clamping plates, and the end of the traction rod 311 is rotatably connected to the second rotating shaft. Thus, the traction rod 311 can be rotatably connected to the second rotating shaft fixing seat 313.

[0185] The first slider 322 and the second slider 323 are connected to each other via a connector 324. During movement, the first slider 322 can drive the second slider 323 to move in the opposite direction with the help of the connector 324.

[0186] In actual installation, after the hinge plate is fixedly installed on the housing 500, the second rotating shaft fixing seat 313 can be fixed to the hinge plate using bolts or other structures. For example, the second rotating shaft fixing seat 313 is provided with a through hole. During installation, external bolts can pass through the through hole and connect to the hinge plate, thereby fixing the second rotating shaft fixing seat 313 to the hinge plate.

[0187] Next, the base 321 can be fixed to the door 110 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 bolts can pass through the through holes on the first receiving plate 326 and the second receiving plate 327 and connect to the door 110, thereby fixing the base 321 to the door 110.

[0188] 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.

[0189] In actual use, as shown in Figures 15 and 16, when the cabinet door 110 moves relative to the cabinet body 500 from the position of closed storage space to the position of open storage space, the first pivot fixing seat 312 is fixed to the cabinet door 110 along the hinge seat. During the rotation of the cabinet 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 along the D direction on the second guide rail 3212 through the connecting piece 324. Since the base 321 is fixedly connected to the cabinet door 110 and the second slider 323 is fixedly connected to the cabinet door 200, the cabinet door 200 will move relative to the cabinet door 110 along the D direction. Here, 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 cabinet door 110.

[0190] Correspondingly, when the cabinet door 110 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 110, the first slider 322 will move on the first guide rail 3211 in the opposite direction to the C direction. Correspondingly, the first slider 322 will pull the second slider 323 on the second guide rail 3212 in the opposite direction to the D direction through the connector 324. At this time, the cabinet door 200 will move relative to the cabinet door 110 in the opposite direction to the D direction.

[0191] Wherein, the first guide rail and the second guide rail are a type of track, and the first slider 322 and the second slider 323 are sliding members that are adapted to the corresponding guide rail and can slide along the corresponding guide rail; in addition, the sliding cooperation between the first slider 322 and the first guide rail should at least include the case where there are balls 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 case where there are balls between the second slider 323 and the second guide rail.

[0192] 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, as shown in Figures 15 to 17, the connector 324 includes: a first connector 3241 and a second connector 3242.

[0193] The first connector 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 connector 3242 bypasses the other end of the base 321 and its two ends are respectively connected to the other end of the first slider 322 and the second slider 323.

[0194] For example, the first connector 3241 can be a flexible rope. In the length direction of the base 321, one end of the first connector 3241 is connected to the first slider 322, and the other end is connected to the second slider 323 after passing over one end of the base 321. That is, in the length direction of the base 321, the first connector 3241 passes over one end of the base 321, and its two ends extend toward the first slider 322 and the second slider 323 respectively, and are connected to the first slider 322 and the second slider 323 respectively.

[0195] Correspondingly, one end of the second connector 3242 is connected to the first slider 322, and the other end is connected to the second slider 323 after passing around the other end of the base 321. That is, in the length direction of the base 321, the second connector 3242 passes around the other end of the base 321, and both ends are connected to the first slider 322 and the second slider 323 respectively.

[0196] At this time, 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, respectively, forming a roughly ring-shaped structure.

[0197] For example, in order to ensure that the first connector 3241 and the second connector 3242 can pull the second slider 323 to move normally, as shown in FIG17, the base 321 is provided with a first roller 328 and a second roller 329 on both sides in the length direction, respectively. The first roller 328 and the second roller 329 can support the first connector 3241 and the second connector 3242 respectively.

[0198] Specifically, as shown in Figure 17, there are two first rollers 328, which are spaced apart along the width of the base 321. Each of the two first rollers 328 is rotatably mounted on the first receiving plate 326. To facilitate the receiving of the first connecting member 3241, the outer periphery of each first roller 328 may have a receiving groove along its circumferential direction. Thus, when installing the first connecting member 3241, it can be placed in the receiving groove of the two first rollers 328. Subsequently, when the first slider 322 pulls the second slider 323 with the aid of the first connecting member 3241, the first connecting member 3241 can drive the two first rollers 328 to rotate.

[0199] Similarly, there are two second rollers 329, which are spaced apart along the width of the base 321. Each of the two second rollers 329 is rotatably mounted on the second receiving plate 327. To facilitate the receiving of the second connecting member 3242, the outer periphery of each second roller 329 may also be provided with a receiving groove along its circumferential direction. Thus, when installing the second connecting member 3242, it can be placed in the receiving groove of the two second rollers 329. Subsequently, when the first slider 322 pulls the second slider 323 with the aid of the second connecting member 3242, the second connecting member 3242 can drive the two second rollers 329 to rotate.

[0200] Therefore, in the above configuration, the first roller 328 can support and limit the first connector 3241, and the second roller 329 can support and limit the second connector 3242. The first roller 328 and the second roller 329 can prevent the first connector 3241 and the second connector 3242 from contacting other parts and causing wear and tear during movement, thus providing effective protection for the first connector 3241 and the second connector 3242.

[0201] 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 110 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.

[0202] Finally, it should be noted that the terms "parallel" and "perpendicular" in the embodiments of this invention should not be strictly limited to a geometric sense. At least manufacturing and installation errors should be considered. For example, an error of ±10° should be within the protection range of the embodiments of this invention. Furthermore, the above embodiments are only used to illustrate the technical solutions of this invention and are not intended to limit it. Although the invention 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; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this invention.
