[0051] As Figure 2 shown, the door body device in the embodiment of the present utility model includes: a box door 100, a cabinet door 200, and a sliding door mechanism 300. Among them, the box door 100 is rotatably connected to the box body 500 and is adapted to open or close the storage space of the box body 500; the cabinet door 200 is slidably disposed outside the box door 100; the sliding door mechanism 300 includes a connected traction assembly 310 and a sliding door assembly 320. The traction assembly 310 is at least disposed on the bottom wall 501 of the box body 500, and the sliding door assembly 320 is disposed on the box door 100 and is connected to the cabinet door 200. The traction assembly 310 is configured to drive the sliding door assembly 320 to act during the opening or closing process of the box door 100, and further drive the cabinet door 200 to move in the width direction of the box door 100.

[0052] Among them, the thickness of the cabinet door 100 is 18 - 60 mm. Exemplarily, the thickness of the cabinet door 100 is 18 mm, 25 mm, 50 mm, 60 mm, etc. The thickness of the door 200 is 12 - 26 mm. Exemplarily, the thickness of the door 200 is 12 mm, 18 mm, 24 mm, 26 mm, etc. Additionally, the door 200 can be a wooden door or a plastic door, etc.

[0053] It can be understood that the door device in this embodiment can be used in refrigeration equipment such as refrigerators, freezers, ice makers, etc. Among them, the refrigeration equipment includes a cabinet 500, and a storage space is formed in the cabinet 500, and items such as vegetables and fruits that need to be refrigerated or frozen can be placed in the storage space. Optionally, a refrigeration device and the like are also provided in the cabinet 500 of the refrigeration equipment, and the refrigeration device can perform refrigeration treatment on the storage space.

[0054] In this embodiment, the cabinet door 100 in the door device is rotatably arranged on the cabinet 500 of the refrigeration equipment through a hinge 400. The cabinet door 100 can be used to open or close the storage space in the cabinet 500. When the cabinet door 100 is in the closed position closing the storage space, the storage space is in a closed state, and the items in the storage space can be refrigerated. When the cabinet door 100 is in the open position opening the storage space, the storage space is in an open state, and the user can take out the items in the storage space.

[0055] For the convenience of describing the positional relationship between various components, in this embodiment, as Figure 2 shown, the cabinet 500 is generally configured as a cuboid structure with a certain height. The cabinet 500 can be placed on a horizontal plane. The cabinet 500 has a height direction, a width direction, and a thickness direction that are perpendicular to each other. Among them, the height direction of the cabinet 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.

[0056] A storage space is provided inside the cabinet 500. An opening is provided on the side of the cabinet 500 in the thickness direction, and the opening communicates with the storage space. The cabinet door 100 is connected to the side of the cabinet 500 in the thickness direction where the opening is provided. The cabinet door 100 extends along the width direction of the cabinet 500. A hinge 400 is connected to one side of the cabinet door 100 in the width direction of the cabinet 500. The cabinet door 100 can be rotatably connected to the cabinet 500 via the hinge 400, so as to ensure that the cabinet door 100 can open or close the storage space of the cabinet 500.

[0057] Moreover, the side of the cabinet 500 where the cabinet door 100 is installed is the front, that is, the cabinet door 100 is installed on the front of the cabinet 500.

[0058] The box door 100 is generally constructed as a flat plate-like structure with a certain thickness. The box door 100 has a height direction, a width direction, and a thickness direction that are perpendicular to each other. Among them, the height direction of the box door 100 is parallel to the vertical direction, and the width direction and the length direction are located in the horizontal plane and are perpendicular to each other. One side of the box door 100 in the width direction can be rotatably connected to the box body 500 via a hinge 400. For example, as Figure 2 shown, a hinge 400 is connected to the right side of the box door 100 in the width direction of the box body 500, and the box door 100 can be rotatably connected to the box body 500 via this hinge 400.

[0059] Moreover, when the box door 100 is in the position state of closing the storage space of the box body 500, the width direction of the box door 100 is parallel to the width direction of the box body 500, and the thickness direction of the box door 100 is parallel to the thickness direction of the box body 500.

[0060] Furthermore, the cabinet door 200 can be a decorative door panel. The cabinet door 200 is constructed as a flat plate-like structure with a certain thickness. The cabinet door 200 is connected to the outer side of the box door 100 facing away from the box body 500. When the refrigeration device is placed together with the cabinet in an embedded manner or directly placed in the cabinet, after the box door 100 is in the closed position, the cabinet door 200 can be flush with the door panel of the cabinet, that is, the outer wall surface of the cabinet door 200 facing away from the box door 100 can be flush with the outer wall surface of the cabinet.

[0061] In the actual use scenario, the outer wall surface of the cabinet door 200 can be selected to have the same material and shape as the outer wall surface of the cabinet, and the same decoration can be attached, so that the refrigeration device can have sufficient coordination with the cabinet and ensure the aesthetics.

[0062] After the door body device in this embodiment is installed on the box body 500 of the refrigeration device, when the box door 100 rotates relative to the box body 500 to open or close the storage space of the box body 500, the sliding door mechanism 300 can drive the cabinet door 200 to move relative to the box door 100 in the width direction of the box door 100. Thus, when the refrigeration device is placed in the cabinet in an embedded placement manner, without affecting the user experience while ensuring coordination and aesthetics, interference between the cabinet door 200 and the cabinet can be avoided during the process of opening the box door 100.

[0063] In one embodiment, as Figure 1 shown, the door body device and the box body 500 are configured to be arranged in the installation space formed between the first cabinet 510 and the second cabinet 520; during the process of opening or closing the box door 100, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the box door 100, so that the cabinet door 200 avoids the side walls of the first cabinet 510 and the second cabinet 520;

[0064] Alternatively, the door body device and the cabinet body 500 are configured to be disposed in a cabinet; during the opening or closing process of the box door 100, the sliding door mechanism 300 is configured to drive the cabinet door 200 to move a preset distance on the box door 100, so that the cabinet door 200 avoids the side wall of the cabinet body.

[0065] It can be understood that the refrigeration device includes a door body device and a cabinet body 500.

[0066] In practice, as Figure 1 shown, when the refrigeration device having the door body device and the cabinet body 500 is placed between adjacent first cabinet body 510 and second cabinet body 520, a cabinet door 200 can be disposed on the outer side of the box door 100 in the door body device, and the cabinet door 200 can move relative to the box door 100 in the width direction of the box door 100. Optionally, when the box door 100 is in a state of closing the storage space of the cabinet body 500, the outer wall surface of the cabinet door 200 facing away from the box door 100 can be flush with the outer wall surfaces of the first cabinet body 510 and the second cabinet body 520, and the outer wall surfaces of the first cabinet body 510 and the second cabinet body 520 and the outer wall surface of the cabinet door 200 facing away from the box door 100 are in the same direction in the thickness direction of the cabinet body 500.

[0067] At this time, during the rotation process of the box door 100 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.

[0068] Alternatively, after the refrigeration device is placed in the cabinet body, a cabinet door 200 can be disposed on the outer side of the box door 100 of the door body device, and the cabinet door 200 can move relative to the box door 100. Optionally, when the box door 100 is in a state of closing the storage space of the cabinet body 500, the outer wall surface of the cabinet door 200 facing away from the box door 100 can be flush with the outer wall surface of the cabinet body, and the outer wall surface of the cabinet body and the outer wall surface of the cabinet door 200 facing away from the box door 100 are in the same direction in the thickness direction of the cabinet body 500.

[0069] At this time, during the rotation process of the box door 100 relative to the cabinet body 500, the sliding door mechanism 300 can drive the cabinet door 200 to move, and can also make the cabinet door 200 avoid the side wall of the cabinet body.

[0070] Further, in an embodiment, the number of the box doors 100 is multiple, and each box door 100 corresponds to at least one storage space; each box door 100 is rotatably connected to the cabinet body 500 through a plurality of hinges 400. Among them, the box door 100 at the bottom is rotatably connected to the cabinet body 500 through a first hinge 410 disposed on the lower cross beam of the cabinet body 500, and the traction assembly 310 corresponding to the box door 100 at the bottom of the cabinet body 500 is disposed close to the first hinge 410.

[0071] It can be understood that according to different refrigeration requirements, the cabinet 500 of different refrigeration devices can be provided with different numbers of storage spaces. These storage spaces are arranged at intervals along the height direction of the cabinet 500. Some storage spaces are for refrigeration, and some storage spaces are for freezing. Correspondingly, in order to be able to selectively close these storage spaces, the number of cabinet doors 100 can be multiple, and each cabinet door 100 corresponds to at least one of the storage spaces.

[0072] For example, as Figure 2 shown, the cabinet 500 is provided with two storage spaces at intervals in the vertical direction. These two storage spaces can be used for refrigeration and freezing respectively. The number of cabinet doors 100 is two, namely the first cabinet door 110 and the second cabinet door 120. These two cabinet doors 100 correspond one-to-one with the positions of the two storage spaces. At this time, the two storage spaces can be opened or closed independently through these two cabinet doors 100.

[0073] For another example, the cabinet 500 can be provided with three storage spaces at intervals in the vertical direction, namely the first space, the second space and the third space. The first space and the second space are for refrigeration, and the second space is for freezing. The number of cabinet doors 100 is two, namely the first cabinet door 110 and the second cabinet door 120. Among them, the first cabinet door 110 corresponds one-to-one with the positions of the first space and the second space at the same time, and the second cabinet door 120 corresponds to the position of the third space. At this time, the first space and the second space can be opened or closed simultaneously by using the first cabinet door 110, and the opening and closing state of the third space can be independently controlled by using the second cabinet door 120.

[0074] It can be understood that in this embodiment, each cabinet door 100 can correspond to a single storage space. At this time, the cabinet door 100 can independently control the opening and closing state of the storage space. In actual use, according to requirements, each cabinet door 100 can also correspond to multiple adjacent storage spaces. At this time, the cabinet door 100 can simultaneously control the opening and closing states of the multiple storage spaces.

[0075] In a specific embodiment, as Figure 2 shown, the door body device includes a first cabinet door 110 and a second cabinet door 120. The first cabinet door 110 and the second cabinet door 120 are arranged at intervals along the height direction of the cabinet 500. At this time, the bottom of the second cabinet door 120 can be rotatably connected to the cabinet 500 by means of a first hinge 410 provided on the lower cross beam of the cabinet 500, and the top of the first cabinet door 110 can be rotatably connected to the cabinet 500 by means of a third hinge 430 provided on the top wall of the cabinet 500.

[0076] Correspondingly, as Figure 3As shown, the traction assembly 310 located on the bottom wall 501 of the box body 500 is disposed close to the first hinge 410. Under the action of the traction assembly 310, the sliding door assembly 320 can drive the cabinet door 200 corresponding to the second box door 120 to move relative to the width direction of the second box door 120.

[0077] Further, in order to effectively realize the installation of the box door 100, the hinge 400 may further include a second hinge 420. Wherein, the second hinge 420 is disposed on the front surface (middle cross beam) of the box body 500, and the second hinge 420 is located between the first hinge 410 and the third hinge 430.

[0078] Exemplarily, since multiple box doors 100 are arranged at intervals in the height direction of the box body 500, a second hinge 420 may be disposed at a position between two adjacent box doors 100, and at least one of the two adjacent box doors 100 may be rotatably connected to the box body 500 by means of the second hinge 420.

[0079] In practical applications, the number of the second hinges 420 may be one or two. For example, when the number of the second hinges 420 is one, one of the two adjacent box doors 100 may be connected to the second hinge 420 and rotatably connected to the box body 500 by means of the one second hinge 420, or the two adjacent box doors 100 may be simultaneously connected to the second hinge 420 and simultaneously rotatably connected to the box body 500 by means of the one second hinge 420.

[0080] For example, as Figure 2 shown, the box door 100 includes a first box door 110 and a second box door 120. At this time, the second hinge 420 may be disposed between the first box door 110 and the second box door 120, and the bottom of the first box door 110 and the top of the second box door 120 may be simultaneously hinged to the second hinge 420, so as to be rotatably connected to the box body 500.

[0081] In yet another embodiment, when the number of the second hinges 420 is two, the two second hinges 420 may be arranged at intervals in the height direction of the box body 500. At this time, the two adjacent box doors 100 may be respectively hinged to the two second hinges 420, and then rotatably connected to the box body 500 by means of their respective second hinges 420.

[0082] Further, in one embodiment, as Figure 4As shown, the first hinge 410 includes a first hinge plate 411 and a first hinge shaft 412. The first hinge plate 411 includes a support plate 4111 and an extension plate 4112. The support plate 4111 is installed on the front surface (lower cross beam) of the box body 500. The extension plate 4112 is connected to one side of the support plate 4111 facing away from the front surface of the box body 500. The support plate 4111 and the extension plate 4112 are arranged at an angle. The first hinge shaft 412 is arranged on the top surface of the extension plate 4112 and extends upward. The bottom of the second door 120 is hinged to the first hinge shaft 412.

[0083] Similarly, the first hinge plate 411 and the first hinge shaft 412 can also be made of metal or non-metal materials with a certain structural strength. The first hinge plate 411 includes a support plate 4111 and an extension plate 4112 that are connected to each other. The extension plate 4112 is substantially perpendicular to the support plate 4111. The two can be integrally formed by stamping or other methods. The support plate 4111 is provided with a plurality of mounting holes. The first hinge shaft 412 is fixedly arranged on the extension plate 4112 by welding or threaded connection or other methods.

[0084] During actual installation, a plurality of threaded holes can be set in advance at a position on the front surface of the box body 500 and close to the bottom. Then, let one side in the thickness direction of the support plate 4111 fit to the front surface of the box body 500. Then, make the mounting holes on the support plate 4111 correspond to the positions of the threaded holes. Then, fix the support plate 4111 to the front surface of the box body 500 with bolts. The extension plate 4112 is connected to the other side in the thickness direction of the support plate 4111 and extends toward the direction where the door 100 is located. Moreover, the first hinge shaft 412 extends upward along the height direction of the box body 500.

[0085] Based on this, when installing the door 100, a hinge hole can be set in advance at the bottom of the door 100 corresponding to the first hinge 410. Then, insert the first hinge shaft 412 into the hinge hole. Thus, the installation of the door 100 can be realized.

[0086] In this way, the traction assembly 310 on the bottom wall 501 of the box body 500 is arranged close to the first hinge plate 411. In addition, as Figure 3 shown, the traction assembly 310 is arranged in the installation area A. The installation area A is located on the bottom wall 501 of the box body 500. The installation area A includes a first side, a second side, a third side, and a fourth side. The first side and the third side are oppositely arranged. The second side and the fourth side are oppositely arranged. The first side is located in the plane where the side surface of the box body 500 is located. The second side is located in the plane where the front surface of the box body 500 is located. In the width direction of the box body 500, there is a first distance between the third side and the first side; in the thickness direction of the box body 500, there is a second distance between the fourth side and the second side.

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

[0088] Further, in one embodiment, as Figure 5 shown, the second hinge 420 includes a second hinge plate 421, a second hinge shaft 422, and a third hinge shaft 423. The second hinge plate 421 includes a mounting plate 4211 and a connecting plate 4212. The mounting plate 4211 is mounted on the front surface (middle cross member) of the box body 500. The connecting plate 4212 is connected to a side of the mounting plate 4211 facing away from the front surface of the box body 500. The connecting plate 4212 is disposed at an angle with respect to the mounting plate 4211. The connecting plate 4212 has opposite first and second sides. The second hinge shaft 422 is disposed on the first side, and the bottom of the first door 110 is hinged to the second hinge shaft 422. The third hinge shaft 423 is disposed on the second side, and the top of the second door 120 is hinged to the third hinge shaft 423. The second hinge 420 may be provided with at least one traction assembly 310. Wherein, in the case of having two traction assemblies 310, one traction assembly 310 corresponds to the first door 110, and the other traction assembly 310 corresponds to the second door 120.

[0089] Exemplarily, the second hinge plate 421 may be made of a metallic material or a non-metallic material having a certain structural strength. The second hinge plate 421 includes a mounting plate 4211 and a connecting plate 4212 that are connected to each other. The connecting plate 4212 is substantially perpendicular to the mounting plate 4211, and a plurality of mounting holes are provided on the mounting plate 4211. During actual production and manufacturing, the mounting plate 4211 and the connecting plate 4212 may be integrally formed on the same sheet of material. Subsequently, the connecting plate 4212 may be bent relative to the mounting plate 4211 by means of stamping and folding.

[0090] The two sides in the thickness direction of the connecting plate 4212 are respectively the first side and the second side. The second hinge shaft 422 is fixedly connected to the first side, and the third hinge shaft 423 is fixedly connected to the second side.

[0091] During actual production and manufacturing, the second hinge shaft 422 and the third hinge shaft 423 may be respectively fixedly connected to the connecting plate 4212 by welding. Alternatively, the second hinge shaft 422 and the third hinge shaft 423 may be configured as an integral member in the shape of a long bar. The connecting plate 4212 is provided with through holes penetrating along its thickness direction. The integral member is inserted into the through holes, and the integral member is fixed in the through holes by welding or threaded connection. The two ends of the integral member in the length direction on the connecting plate 4212 are respectively formed as the second hinge shaft 422 and the third hinge shaft 423.

[0092] During actual installation, multiple threaded holes can be set in advance on the front surface of the cabinet body 500 according to the installation position of the cabinet door 100. For example, as Figure 2 shown, multiple threaded holes are set at the position corresponding to the gap between the first cabinet door 110 and the second cabinet door 120 on the front surface of the cabinet body 500. Then, the mounting holes on the mounting plate 4211 of the second hinge plate 421 are aligned with the positions of the threaded holes, and the mounting plate 4211 is fixed to the front surface of the cabinet body 500 by means of bolts. At this time, the connecting plate 4212 extends towards the direction of the cabinet door 100. Meanwhile, the second hinge shaft 422 extends upwards along the height direction of the cabinet body 500, and the third hinge shaft 423 extends downwards along the height direction of the cabinet body 500.

[0093] Based on this, when installing the cabinet door 100, a hinge hole can be set in advance at the bottom of the cabinet door 100 corresponding to the second hinge shaft 422, and a hinge hole can be set in advance at the top of the cabinet door 100 corresponding to the third hinge shaft 423. Then, the second hinge shaft 422 and the third hinge shaft 423 can be respectively inserted into the hinge holes of their corresponding cabinet doors 100, thereby realizing the installation of the cabinet door 100.

[0094] Furthermore, in one embodiment, as Figure 6 shown, the third hinge 430 includes a third hinge plate 431 and a fourth hinge shaft 432. A part of the third hinge plate 431 covers the top wall of the cabinet body 500 and the remaining part protrudes from the top wall towards the corresponding cabinet door 100. The fourth hinge shaft 432 extends downwards from the part of the third hinge plate 431 protruding from the top wall, and the top of the first cabinet door 110 is hinged to the fourth hinge shaft 432. Among them, the third hinge 430 can be provided with a traction assembly 310 corresponding to the first cabinet door 110.

[0095] Exemplarily, the third hinge plate 431 and the fourth hinge shaft 432 can be made of a metal or non-metal material with a certain structural strength. The third hinge plate 431 includes a first fitting part and a first protruding part connected to each other. The first fitting part is provided with multiple mounting holes, and the fourth hinge shaft 432 is fixedly arranged on the first protruding part by means of welding or threaded connection, etc.

[0096] During actual installation, multiple threaded holes can be set in advance on the top wall of the cabinet body 500. Then, the first fitting part of the third hinge plate 431 is fitted to the top wall of the cabinet body 500, and at the same time, the mounting holes on the first fitting part are aligned with the positions of the threaded holes. The first fitting part is fixed to the top wall of the cabinet body 500 by means of bolts. At this time, the first fitting part can cover and fit to the top wall of the cabinet body 500, the first protruding part can protrude from the top wall towards the cabinet door 100, and moreover, the fourth hinge shaft 432 can extend downwards along the height direction of the cabinet body 500.

[0097] Based on this, when installing the cabinet door 100, a hinge hole can be set in advance at the top of the cabinet door 100 corresponding to the fourth hinge 400, and then the fourth hinge shaft 432 is inserted into the hinge hole, thereby realizing the installation of the cabinet door 100.

[0098] In another alternative embodiment, the number of cabinet doors 100 is two, and the two cabinet doors 100 are arranged side by side. Each cabinet door 100 is provided with a corresponding cabinet door 200 and a sliding door mechanism 300. At least one of the two traction components 310 is arranged on the top wall of the box body 500.

[0099] It should be noted that each cabinet door 100 can be provided with one or two sliding door mechanisms 300. In the case where it is provided with one sliding door mechanism 300, the corresponding traction component 310 is arranged on the bottom wall 501 of the box body 500. In the case where it is provided with two sliding door mechanisms 300, one of the corresponding traction components 310 is arranged on the bottom wall 501 of the box body 500, and the other traction component 310 can be arranged on the bottom wall 501, side surface, lower cross beam, etc. of the box body 500.

[0100] In one embodiment, in order to ensure that the traction component 310 can drive the sliding door component 320 to move, the traction component 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 component 320, the second rotating shaft fixing seat 313 is connected to the bottom wall 501 of the box body 500, 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 process of the cabinet door 100, the traction rod 311 drives the sliding door component 320 to act, thereby driving the cabinet door 200 to move relative to the width direction of the cabinet door 100. Among them, the second rotating shaft fixing seat 313 is located in the installation area A.

[0101] Exemplarily, the hinge 400 can include a hinge plate and a hinge shaft, and the hinge shaft is fixedly arranged on the hinge plate by means of welding or the like. During actual installation, the hinge plate can be fixedly arranged on the box body 500 by means of bolts or other structures. The cabinet door 100 can 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 cabinet door 100, thereby realizing the rotational connection of the cabinet door 100 relative to the box body 500.

[0102] In the traction component 310, the first rotating shaft fixing seat 312 is arranged on the sliding door component 320, the second rotating shaft fixing seat 313 is arranged on the bottom wall 501 and close to the hinge plate, and both ends of the traction rod 311 are rotatably connected to the first rotating shaft fixing seat 312 and the second rotating shaft fixing seat 313 respectively.

[0103] In actual use, when the door 100 rotates between positions for opening or closing the storage space relative to the box body 500, the traction assembly 310 can pull the sliding door assembly 320 to act, so that the sliding door assembly 320 drives the cabinet door 200 to move relative to the door 100 in the width direction of the door 100.

[0104] Furthermore, in one embodiment, in order to enable the sliding door assembly 320 to effectively drive the cabinet door 200 to move relative to the door 100 under the drive of the traction assembly 310, as Figure 7 and Figure 8 shown, the sliding door assembly 320 includes: a base 321, a first slider 322, a second slider 323 and a connecting member 324.

[0105] Specifically, a first guide rail is formed on one side of the base 321, and a second guide rail is formed on the other side; the first slider 322 is slidably disposed on the first guide rail, and the first rotating shaft fixing seat 312 is connected to the first slider 322; the second slider 323 is slidably disposed on the second guide rail and is connected to the cabinet door 200; both ends of the connecting member 324 are respectively connected to the first slider 322 and the second slider 323.

[0106] During the opening or closing process of the door 100, the traction rod 311 drives the first slider 322 to move on the first guide rail, and the first slider 322 drives the second slider 323 to move in the opposite direction on the second guide rail through the connecting member 324.

[0107] Exemplarily, the base 321 has a first guide rail and a second guide rail arranged side by side and spaced apart. The first slider 322 is disposed on the first guide rail, and the first slider 322 can slide along the length direction of the first guide rail. The second slider 323 is disposed on the second guide rail, and the second slider 323 can slide along the length direction of the second guide rail. Moreover, the first slider 322 and the second slider 323 are connected by the connecting member 324. When the first slider 322 moves on the first guide rail, the first slider 322 can pull the second slider 323 to move on the second guide rail through the connecting member 324, and the moving direction of the second slider 323 is opposite to the moving direction of the first slider 322.

[0108] As a specific implementation manner, as Figure 7 and Figure 8As shown, the two opposite sides of the base 321 in the thickness direction are the first side and the second side respectively. U-shaped grooves are formed on the first side and the second side respectively. The U-shaped groove on the first side is the first guide rail, and the U-shaped groove on the second side is the second guide rail. The first guide rail and the second guide rail extend along the length direction of the base 321. The first slider 322 is slidably arranged in the first guide rail, and the second slider 323 is slidably arranged in the second guide rail. Moreover, the first rotating shaft fixing seat 312 is connected to the first slider 322, and the cabinet door 200 can be fixedly connected to the second slider 323.

[0109] Considering the requirements in practical applications, limit structures can also be provided at the ends on both sides of the first guide rail and the second guide rail. Through the limitation of the limit structures, the first slider 322 and the second slider 323 can move within a set moving range, so as to set the moving distance according to requirements to meet the usage requirements in different scenarios.

[0110] Correspondingly, the traction rod 311 is configured as a long straight rod. One end of the traction rod 311 is rotatably connected to the first rotating shaft fixing seat 312 via the first rotating shaft, and the other end is rotatably connected to the second rotating shaft fixing seat 313 via the second rotating shaft.

[0111] As an implementation method, as Figure 8 shown, the first rotating shaft fixing seat 312 includes a first vertical plate and a first horizontal plate. The first vertical plate and the first horizontal plate are connected to each other and form an L-shaped structure. The first horizontal plate is provided with a shaft hole, and a first rotating shaft is inserted into the shaft hole. One end of the traction rod 311 is rotatably connected to the first rotating shaft, so as to be fixedly connected to the first rotating shaft fixing seat 312. The first vertical plate can be fixedly connected to the first slider 322 by welding or other means.

[0112] Similarly, as Figure 7 and Figure 8 shown, the second rotating shaft fixing seat 313 includes a second vertical plate and a second horizontal plate. The second vertical plate and the second horizontal plate are connected to each other and form an L-shaped structure. The second horizontal plate is provided with a shaft hole, and a second rotating shaft can be inserted into the shaft hole. The other end of the traction rod 311 is rotatably connected to the second rotating shaft, so as to be rotatably connected to the second rotating shaft fixing seat 313.

[0113] To ensure that the first slider 322 and the second slider 323 can move synchronously and in opposite directions, exemplarily, the connecting member 324 includes a first connecting member 3241 and a second connecting member 3242, and the first connecting member 3241 and the second connecting member 3242 are configured as flexible ropes. In the length direction of the base 321, the first connecting member 3241 bypasses the end of the base 321, and its two ends respectively enter the first guide rail and the second guide rail, and are respectively connected to the first slider 322 and the second slider 323. Correspondingly, the second connecting member 3242 bypasses the other end of the base 321, and its two ends also respectively enter the first guide rail and the second guide rail, and are respectively connected to the first slider 322 and the second slider 323. At this time, the two ends of the first connecting member 3241 are respectively connected to the two ends of the second connecting member 3242 via the first slider 322 and the second slider 323, and form a substantially annular structure.

[0114] During actual installation, after the hinge plate is fixedly installed on the box body 500, the second rotating shaft fixing seat 313 can be fixed on the bottom wall 501 of the box body 500 by means of structures such as bolts.

[0115] Then, the base 321 can be fixed on the box door 100 by means of structures such as bolts. Exemplarily, engaging plates 325 are respectively provided on both sides in the length direction of the base 321, and through holes are respectively provided on the two engaging plates 325. During installation, external bolt holes can pass through the through holes on the two engaging plates 325 and be connected to the box door 100, so as to fix the base 321 on the box door 100.

[0116] After that, 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 connection structures.

[0117] During actual use, as Figure 7 and Figure 8 shown, when the box door 100 moves relative to the box body 500 from the position of closing the storage space towards the position of opening the storage space, the second rotating shaft fixing seat 313 is fixed on the bottom wall 501 of the box body 500. During the rotation of the box door 100, the first slider 322 will move along the first direction on the first guide rail. Correspondingly, the first slider 322 will pull the second slider 323 to move along the second direction on the second guide rail through the first connecting member 3241. Since the base 321 is fixedly connected to the box door 100 and the second slider 323 is fixedly connected to the cabinet door 200, at this time, the cabinet door 200 will move along the second direction relative to the box door 100. Among them, the first direction is opposite to the second direction, and both the first direction and the second direction are parallel to the width direction of the box door 100.

[0118] Correspondingly, when the box door 100 moves from the position of opening the storage space towards the position of closing the storage space relative to the box body 500, during the rotation of the box door 100, the first slider 322 will move along the first guide rail in a direction opposite to the first direction. Correspondingly, the first slider 322 will pull the second slider 323 to move along the second guide rail in a direction opposite to the second direction through the second connecting member 3242. At this time, the cabinet door 200 will move relative to the box door 100 in a direction opposite to the second direction.

[0119] In another embodiment of the present utility model, as Figure 9 and Figure 10 shown, the sliding door mechanism 300 includes: a base 321, a first slider 322, a second slider 323, and a transmission member 328. A first guide rail is formed on one side of the base 321, and a second guide rail is formed on the other side. The first slider 322 is slidably disposed on the first guide rail, and the second slider 323 is slidably disposed on the second guide rail. Both ends of the transmission member 328 are respectively in transmission connection with the first slider 322 and the second slider 323. In the case where the first slider 322 moves on the first guide rail, the first slider 322 drives the second slider 323 to move in the opposite direction along the second guide rail through the connecting member 324.

[0120] The base 321 can be fixed to the box door 100 by means of structures such as bolts. Exemplarily, first receiving plates 326 and second receiving plates 327 are respectively provided on both sides in the length direction of the base 321, and through holes are respectively provided on the first receiving plates 326 and the second receiving plates 327. During installation, external bolt holes can pass through the through holes on the first receiving plates 326 and the second receiving plates 327 and be connected to the box door 100, thereby fixing the base 321 to the box door 100.

[0121] 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 provided on the bottom wall 501 of the box body 500.

[0122] Among them, the first end of the first connecting rod is rotatably provided in the installation area. For example, the first end of the first connecting rod is installed in the installation area through 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 provided on the box door 100 and is meshed and connected to the tooth portion on the first slider 322 through a gear provided at the second end of the second connecting rod.

[0123] It can be understood that the first connecting rod and the second connecting rod are connected by a hinge, 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 100.

[0124] When the second end of the second link rotates in a circular motion with the hinge axis as the center along with the door 100 of the box, since the first end of the first link is arranged offset from the hinge axis, the distance between the second end of the second link and the first end of the first link changes, while the position of the second end of the second link relative to the door 100 of the box remains unchanged. As a result, the second end of the second link rotates around the door 100 of the box, and drives the second slider 323 to drive the cabinet door 200 to move along the width direction of the door 100 of the box.

[0125] In practical applications, during the opening process of the door 100 of the box, the door 100 of the box drives the second end of the second link to rotate relative to the hinge axis. Based on the offset 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 increases, driving the second end of the second link to rotate clockwise relative to the door 100 of the box. Furthermore, it controls the second slider 323 to drive the cabinet door 200 to move along the width direction of the door 100 of the box in a direction away from the hinge 400, that is, to move to the left relative to the door 100 of the box. In this way, it can avoid interference between the cabinet door 200 and the cabinet door 200 on the side cabinet; during the closing process of the door 100 of the box, the door 100 of the box drives the second end of the second link to rotate relative to the hinge axis. Based on the offset 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, driving the second end of the second link to rotate counterclockwise relative to the door 100 of the box. Furthermore, it controls the second slider 323 to drive the cabinet door 200 to move along the width direction of the door 100 of the box in a direction close to the hinge 400, that is, to move to the right relative to the door 100 of the box. In this way, it can ensure that the cabinet door 200 can avoid the cabinet door 200 on the side cabinet when closing the door 100 of the box, and reset the cabinet door 200.

[0126] In an optional embodiment, the first rotating shaft fixing seat 312 is connected to the first slider 322, and the second slider 323 is connected to the cabinet door 200. Among them, the first guide rail and the second guide rail, as a kind of track, the first slider 322 and the second slider 323 are sliding members that are adapted to the corresponding guide rails and can slide along the corresponding guide rails; in addition, the sliding fit between the first slider 322 and the first guide rail should at least include the case where there are balls arranged between the first slider 322 and the first guide rail, and the sliding fit between the second slider 323 and the second guide rail should at least include the case where there are balls arranged between the second slider 323 and the second guide rail.

[0127] As Figure 9 shown, the transmission member 328 includes: a first rack 3281, a second rack 3282, and a gear 3283. Among them, the first rack 3281 is arranged on the first slider 322, and the second rack 3282 is arranged on the second slider 323. The gear 3283 is rotatably arranged on the base 321 and meshes with the first rack 3281 and the second rack 3282.

[0128] In this embodiment, when the first slider 322 slides along the first guide rail, the first rack 3281 slides with the first slider 322. The first rack 3281 meshes with the gear 3283. When the first rack 3281 slides, it drives the gear 3283 to rotate. The second rack 3282 and the first rack 3281 mesh with the two sides of the gear 3283 respectively. When the gear 3283 rotates, it can drive the second rack 3282 to slide in the opposite direction relative to the first rack 3281, thereby driving the second slider 323 to slide in the opposite direction relative to the first slider 322. The structure is simple, convenient and practical.

[0129] As Figure 9 shown, the transmission member 328 further includes: a pin shaft, the pin shaft is arranged on the base 321, and the gear 3283 is rotatably arranged on the pin shaft.

[0130] In this embodiment, the pin shaft is arranged on the base 321 to arrange the gear 3283. The gear 3283 is rotatably arranged on the pin shaft and can rotate around the pin shaft, so as to transmit power between the first rack 3281 and the second rack 3282, make the first rack 3281 and the second rack 3282 slide in opposite directions, and make the first slider 322 and the second slider 323 slide in opposite directions.

[0131] In addition, as described above, in this embodiment, a refrigeration device is further provided. The refrigeration device includes a box body 500 and the door body device described in the above embodiment. Among them, the box body 500 forms a storage space, and the box door 100 is rotatably connected to the box body 500 through a hinge 400 and is adapted to open or close the storage space of the box body 500.

[0132] Finally, it should be noted that: the parallelism and perpendicularity referred to in the embodiments of the present invention should not be strictly limited in the geometric sense. At least manufacturing and installation errors should be considered. For example, errors of plus or minus 10° should be within the scope protected by the embodiments of 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 foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; 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.
