When the box door is closed, the cabinet door can be flush with the door panel of the cabinet, which can ensure coordination and aesthetics. When the box door is opened, the sliding door mechanism can drive the cabinet door to move to avoid interference between the cabinet door and the door panel of the cabinet, and can improve the user experience. The following further describes the door body device and the refrigeration device in this embodiment in conjunction with Figures 3 to 15 as shown to further describe the door body device and the refrigeration device in this embodiment.

[0061] Specifically, in this embodiment, as Figure 3 shown, the door body device includes: a box door 100 and a sliding door mechanism 300.

[0062] Among them, the box door 100 is rotatably connected to the box body 110 and is adapted to open or close the storage space of the box body 110. A cabinet door 200 is slidably provided on the outer side of the box door 100; the sliding door mechanism 300 is configured to drive the cabinet door 200 to move along the width direction of the box door 100 during the opening or closing process of the box door 100.

[0063] The sliding door mechanism 300 can drive the cabinet door 200 to move relative to the box door 100 along the width direction of the box door 100 during the rotation of the box door 100 relative to the box body 110.

[0064] It can be understood that the door device in this embodiment can be used in refrigeration equipment such as a refrigerator. Among them, the refrigeration equipment includes a box body 110, and a storage space is formed in the box body 110, 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 box body 110 of the refrigeration equipment, and the refrigeration device can perform refrigeration processing on the storage space.

[0065] In this embodiment, the box door 100 in the door device is rotatably provided on the box body 110 of the refrigeration equipment. The box door 100 can be used to open or close the storage space in the box body 110. When the box door 100 is in the closed position for closing the storage space, the storage space is in a closed state, and the items in the storage space can be refrigerated. When the box door 100 is in the open position for opening the storage space, the storage space is in an open state, and the user can take out the items in the storage space.

[0066] For the convenience of describing the positional relationship between various components, in this embodiment, as Figure 3 shown, the box body 110 is generally constructed as a cuboid structure with a certain height. The box body 110 can be placed on a horizontal plane. The box body 110 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 body 110 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.

[0067] A storage space is provided inside the box body 110. An opening is provided on the side part of the box body 110 in the thickness direction, and the opening communicates with the storage space. The box door 100 is connected to the side part of the box body 110 in the thickness direction where the opening is provided. The box door 100 extends along the width direction of the box body 110. A hinge shaft extending in the vertical direction is connected to one side of the box door 100 in the width direction of the box body 110. The box door 100 can be rotatably connected to the box body 110 via the hinge shaft, and thus the box door 100 can open or close the storage space of the box body 110.

[0068] Moreover, the door 100 is generally configured as a flat plate-like structure with a certain thickness. The cabinet 110 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 110 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 door 100 in the width direction can be connected to the cabinet 110 via a hinge shaft. For example, as Figure 3 shown, a hinge shaft is connected to the right side of the door 100 in the width direction of the cabinet 110, and the door 100 can be rotatably connected to the cabinet 110 via this hinge shaft.

[0069] When the door 100 is in the position of closing the storage space of the cabinet 110, the width direction of the door 100 is parallel to the width direction of the cabinet 110, and the thickness direction of the door 100 is parallel to the thickness direction of the cabinet 110.

[0070] Furthermore, the door panel 200 can be a decorative door panel. The door panel 200 is configured as a flat plate-like structure with a certain thickness. The door panel 200 is connected to the outer side of the door 100 facing away from the cabinet 110. When the refrigeration device is placed in the cabinet in an embedded manner or directly placed in the cabinet, after the door 100 is in the closed position, the door panel 200 can be flush with the door panel of the cabinet, that is, the outer wall surface of the door panel 200 facing away from the door 100 can be flush with the outer wall surface of the cabinet.

[0071] In the actual use scenario, the outer wall surface of the door panel 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 to make the refrigeration device have sufficient coordination with the cabinet and ensure the aesthetics.

[0072] After the door device in this embodiment is installed on the cabinet 110 of the refrigeration device, when the door 100 rotates relative to the cabinet 110 to open or close the storage space of the cabinet 110, the sliding door mechanism 300 can drive the door panel 200 to move relative to the door 100 in the width direction of the door 100, so that in the embedded placement mode of the refrigeration device and the cabinet, without affecting the coordination and aesthetics and the user experience, the interference between the door panel 200 and the cabinet can be avoided during the process of opening the door 100.

[0073] In one embodiment, as Figure 3 shown, the door device, the cabinet 110, and the door panel 200 are used to be arranged in the installation space formed between the first cabinet 710 and the second cabinet 720; during the process of opening or closing the door 100, the sliding door mechanism 300 is configured to drive the door panel 200 to move a preset distance on the door 100 so that the door panel 200 avoids the side walls of the first cabinet 710 and the second cabinet 720;

[0074] Alternatively, the door body device and the cabinet body 110 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.

[0075] It can be understood that the refrigeration device includes a door body device and a cabinet body 110.

[0076] In practice, as Figure 3 shown, when the refrigeration device having the door body device and the cabinet body 110 is placed between an adjacent first cabinet body 710 and a second cabinet body 720, 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 along 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 110, 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 710 and the second cabinet body 720, and the outer wall surfaces of the first cabinet body 710 and the second cabinet body 720 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 110.

[0077] At this time, during the rotation process of the box door 100 relative to the cabinet body 110, 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 710 and the second cabinet body 720.

[0078] Alternatively, after the refrigeration device is placed in the cabinet, 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 110, 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, and the outer wall surface of the cabinet 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 110.

[0079] At this time, during the rotation process of the box door 100 relative to the cabinet body 110, the sliding door mechanism 300 can drive the cabinet door 200 to move, so that the cabinet door 200 avoids the side wall of the cabinet.

[0080] In one embodiment, the sliding door mechanism 300 includes a traction assembly 310 and a sliding door assembly 320.

[0081] In the sliding door mechanism 300 of the present embodiment, the traction assembly 310 is connected between the cabinet door 100 and the sliding door assembly 320. The sliding door assembly 320 is disposed on the cabinet door 100 and is connected between the cabinet door 100 and the door 200. During the rotation of the cabinet door 100 relative to the cabinet body 110, the traction assembly 310 can drive the sliding door assembly 320 to act, thereby driving the door 200 to move relative to the cabinet door 100.

[0082] As a specific implementation, the hinge includes a hinge plate and a hinge shaft provided on the hinge plate. The hinge plate is disposed on the cabinet body 110, and the cabinet door 100 is rotatably provided on the cabinet body through the hinge shaft; the traction assembly 310 includes a traction rod, a first rotating shaft fixing seat, and a second rotating shaft fixing seat; the first rotating shaft fixing seat is connected to the sliding door assembly, the second rotating shaft fixing seat is connected to the hinge plate, one end of the traction rod is rotatably connected to the first rotating shaft fixing seat, and the other end of the traction rod is rotatably connected to the second rotating shaft fixing seat; during the opening or closing of the cabinet door 100, the traction rod drives the sliding door assembly to act, thereby driving the door 200 to move in the width direction relative to the cabinet door 100.

[0083] Wherein, the sliding door assembly includes: a first base, a first slider, a second slider, and a connecting member. A first guide rail is formed on one side of the first base, and a second guide rail is formed on the other side; the first slider is slidably disposed on the first guide rail, and the first rotating shaft fixing seat is connected to the first slider; the second slider is slidably disposed on the second guide rail and is connected to the door 200; both ends of the connecting member are respectively connected to the first slider and the second slider; during the opening or closing of the cabinet door 100, the traction rod drives the first slider to move on the first guide rail, and the first slider drives the second slider to move in the opposite direction on the second guide rail through the connecting member. Wherein, the connecting member includes: a first connecting member and a second connecting member. The first connecting member bypasses one end of the first base, and both ends are respectively connected to one end of the first slider and the second slider; the second connecting member bypasses the other end of the first base, and both ends are respectively connected to the other end of the first slider and the second slider.

[0084] Exemplarily, the traction assembly 310 can obtain a rotational driving force based on the rotation of the cabinet door 100 relative to the cabinet body 110. The sliding door assembly 320 can obtain the rotational driving force and generate a translational driving force, thereby enabling the sliding door assembly 320 to drive the door 200 to translate relative to the cabinet door 100 by using the translational driving force.

[0085] Optionally, the door 200 can be slidably connected to the cabinet door 100 by means of a linear guide rail 400 and other structures and can move along the width direction of the cabinet door 100.

[0086] As a specific implementation manner, the traction assembly 310 may include a driving member and a driving wheel, the sliding door assembly 320 includes a driven wheel and a rack, the driving wheel is disposed on the driving member, the driving wheel and the driven wheel mesh with each other, the driven wheel meshes with the rack, the driving member is disposed on the cabinet door 100, the driven wheel is rotatably disposed on the cabinet door 100, and the rack extends along the width direction of the cabinet door 100 and is disposed on the cabinet door 200. During the rotation of the cabinet door 100 relative to the cabinet body 110, the driving member may be configured to drive the driving wheel to rotate according to the rotation angle of the cabinet door 100. During the rotation of the driving wheel, the driving wheel drives the driven wheel to rotate, and the driven wheel drives the rack to move in the width direction of the cabinet door 100, so that the cabinet door 200 moves relative to the cabinet door 100.

[0087] In addition to the above-mentioned electrically controlled implementation manner, the movement of the cabinet door 200 relative to the cabinet door 100 can also be achieved by means of a mechanical structure.

[0088] As a specific implementation manner, the cabinet door 100 is rotatably connected to the cabinet body 110 via a hinge shaft, and moreover, the hinge shaft is fixedly connected to the cabinet body 110. The traction assembly 310 may include a gear set, the sliding door assembly 320 includes a driven wheel and a rack, the gear set includes a plurality of meshing gears, one gear in the gear set is fixedly disposed on the hinge shaft, this gear is coaxially disposed with the hinge shaft, and several other gears in the gear set are rotatably disposed on the cabinet door 100 and also mesh with the driven wheel. The driven wheel is rotatably disposed on the cabinet door 100, and the rack extends along the width direction of the cabinet door 100 and is disposed on the cabinet door 200. At this time, during the rotation of the cabinet door 100 relative to the cabinet body 110, the cabinet door 100 also rotates synchronously relative to the rotation axis, the gear set can rotate relative to the rotation axis and can drive the driven wheel to rotate, and the driven wheel drives the rack to move in the width direction of the cabinet door 100, so that the cabinet door 200 moves relative to the cabinet door 100.

[0089] It can be understood that the above implementation manners are only exemplary descriptions. The traction assembly 310 can mainly obtain a rotational driving force according to the rotation of the cabinet door 100, and the sliding door assembly 320 can obtain this rotational driving force and convert it into a translational driving force for driving the cabinet door to move. Other methods can also be adopted in practical applications.

[0090] In actual use, when the door body device in this embodiment is installed on the cabinet body 110 of the refrigeration device, during the rotation of the cabinet door 100 relative to the cabinet body 110, the sliding door assembly 320 can drive the cabinet door 200 to move relative to the cabinet door 100 under the drive of the traction assembly 310. Thus, in the case of an embedded placement method of the refrigeration device and the cabinet, without affecting the coordination, aesthetics and the user experience, the interference between the cabinet door 200 and the cabinet can be avoided during the opening of the cabinet door 100.

[0091] Further, in the present embodiment, as Figure 4 and Figure 5 shown, the traction assembly 310 includes a driving tooth portion 311 and a fixed tooth portion 312. The fixed tooth portion 312 is adapted to be disposed on the cabinet 110, the driving tooth portion 311 is disposed on the sliding door assembly 320, and the fixed tooth portion 312 is meshed and connected with the driving tooth portion 311.

[0092] Exemplarily, in order to enable the traction assembly 310 to normally drive the sliding door assembly 320 to act, the fixed tooth portion 312 is fixedly disposed on the cabinet 110. The fixed tooth portion 312 has a plurality of gears, the driving tooth portion 311 is disposed on the sliding door assembly 320, and the driving tooth portion 311 also has a plurality of gears. The gears in the fixed tooth portion 312 are meshed and connected with the gears in the driving tooth portion 311.

[0093] In actual use, after the door device in the present embodiment is installed on the cabinet 110 of the refrigeration device, during the process of the door 100 rotating relative to the cabinet 110, the fixed tooth portion 312 remains stationary, the driving tooth portion 311 can move along with the door 100. At the same time, under the meshing relationship between the fixed tooth portion 312 and the driving tooth portion 311, the driving tooth portion 311 can also rotate. At this time, during the rotation of the driving tooth portion 311, the sliding door assembly 320 can obtain a translational driving force by using the rotational driving force generated during the rotation of the driving tooth portion 311, so as to drive the door 100 to move relative to the cabinet door 200.

[0094] Wherein, the sliding door assembly 320 includes a rack. The rack is slidably disposed on the door 100 and connected to the cabinet door 200, and the driving tooth portion 311 is meshed and connected with the rack. In addition, the rack can be slidably disposed on the door 100 through a guide rail.

[0095] In one embodiment, as Figure 4 and Figure 5 shown, the traction assembly 310 further includes a transmission gear set 313. The transmission gear set 313 is rotatably disposed on the door 100, and the fixed tooth portion 312 is meshed and connected with the driving tooth portion 311 through the transmission gear set 313.

[0096] Exemplarily, in order to ensure that the fixed tooth portion 312 can effectively drive the driving tooth portion 311 to rotate, the fixed tooth portion 312, the transmission gear set 313 and the driving tooth portion 311 are sequentially meshed and connected. During the rotation of the fixed tooth portion 312, it can drive the driving tooth portion 311 to rotate through the transmission gear set 313. After that, the driving tooth portion 311 can generate a rotational driving force to drive the sliding door assembly 320 to move, so as to drive the cabinet door 200 to move relative to the door 100.

[0097] Further, as Figure 3 and Figure 4As shown, the door 100 is adapted to be rotatably connected to the box body 110 through a hinge. The hinge includes a hinge plate 111, and a fixed tooth portion 312 is provided on the side of the hinge plate 111 facing the door 100.

[0098] Exemplarily, a plurality of mounting holes are provided at the first end of the hinge plate 111, and a fixed tooth portion 312 is provided at the second end. During actual installation, the first end of the hinge plate 111 can be fixed to the top or bottom of the box body 110 by means of bolts. The second end of the hinge plate 111 extends towards the door 100 along the thickness direction of the box body 110, and the fixed tooth portion 312 is provided at the second end of the hinge plate 111 facing the door 100.

[0099] Moreover, the rotation axis for rotatably connecting the door 100 to the box body 110 can also be provided at the second end of the hinge plate 111.

[0100] In one embodiment, the door 100 is rotatably connected to the box body 110 through a rotation axis. One end of the rotation axis can be fixedly provided at the second end of the hinge plate 111 by means such as welding, and the other end extends vertically and is inserted into the door 100. Thus, the door 100 can be rotated relative to the box body 110.

[0101] In one embodiment, as Figure 5 and Figure 6 shown, the fixed tooth portion 312 is an arc-shaped rack, and teeth are provided at the concave surface of the arc-shaped rack. The driving tooth portion 311 is meshed and connected to the teeth.

[0102] Exemplarily, the concave surface of the arc-shaped rack can extend along the circumferential direction of the hinge axis connecting the door 100 and the box body 110. A plurality of teeth are sequentially provided on the concave surface, and the driving tooth portion 311 is meshed and connected to the plurality of teeth on the concave surface.

[0103] Thus, during the rotation of the door 100 relative to the box body 110, the transmission gear set 313 can rotate on the fixed tooth portion 312. The transmission gear set 313 transmits the rotational driving force to the driving tooth portion 311, so that the driving tooth portion 311 drives the sliding door assembly 320 to move.

[0104] To achieve transmission connection, as Figure 5 and Figure 6 shown, the transmission gear set 313 includes a first gear 3131, a second gear 3132, and a third gear 3133. The first gear 3131 is meshed and connected to the fixed tooth portion 312. The second gear 3132 and the third gear 3133 are coaxially connected, and the second gear 3132 is meshed and connected to the first gear 3131. The third gear 3133 is meshed and connected to the driving tooth portion 311.

[0105] Exemplarily, the cabinet door 100 has a certain width. To achieve installation, the sliding door mechanism 300 includes a base 120, which is configured as a plate-like structure with a certain length. The base 120 is disposed on the cabinet door 100 and extends along the width direction of the cabinet door 100. The base 120 can be located near the hinge plate 111. For example, as Figure 4 shown, in this embodiment, the hinge plate 111 is connected to the top of the cabinet body 110, and the fixed tooth portion 312 is disposed on the hinge plate 111, then the base 120 can be correspondingly disposed on the top of the cabinet door 100. In other embodiments, when the fixed tooth portion 312 is disposed at the bottom of the cabinet body 110, the base 120 also needs to be correspondingly disposed on the top of the cabinet door 100.

[0106] In this embodiment, both the transmission gear set 313 and the driving tooth portion 311 in the traction assembly 310 are disposed on the base 120.

[0107] As an implementation manner, a plurality of rotating shafts extending in the vertical direction are disposed on the base 120. The first gear 3131 and the second gear 3132 are disposed on these rotating shafts and can rotate around their respective rotating shafts, as Figure 5 and Figure 6 shown. The first gear 3131 meshes with the gear of the fixed tooth portion 312, the second gear 3132 meshes with the first gear 3131, the third gear 3133 is coaxially disposed and fixedly connected with the second gear 3132, and the third gear 3133 meshes with the driving tooth portion 311.

[0108] Thus, during the rotation of the cabinet door 100 relative to the cabinet body 110, the first gear 3131 can rotate on the fixed tooth portion 312, the second gear 3132 can rotate driven by the first gear 3131, the third gear 3133 rotates synchronously with the second gear 3132, and the driving tooth portion 311 can also rotate driven by the third gear 3133, and finally can drive the sliding door assembly 320 to move.

[0109] To be able to adjust the rotation speed of the driving tooth portion 311, the tooth number ratio between the second gear 3132 and the third gear 3133 can be reasonably adjusted. For example, as Figures 4 to 6 shown, during the rotation of the cabinet door 100, to increase the rotation speed of the driving tooth portion 311, the tooth number of the second gear 3132 can be made less than that of the third gear 3133.

[0110] Furthermore, to be able to convert the rotational driving force transmitted by the traction assembly 310 into a translational driving force for driving the cabinet door 200 to move, in addition to the gear-rack structure that can be adopted as described above, a manner of driving the sliding door assembly 320 to move by a rotating member driving a pull rope can also be adopted.

[0111] Specifically, in this embodiment, as Figure 5 and Figure 6 shown, the sliding door assembly 320 includes: a wire winding assembly, a sliding member 340, and a rope assembly.

[0112] Among them, the wire winding assembly includes a wire winding disc 331 and a reversing wheel 332, and the wire winding disc 331 and the reversing wheel 332 are arranged at intervals; the sliding member 340 is arranged between the wire winding disc 331 and the reversing wheel 332; the rope assembly includes a first rope 351 and a second rope 352. The first rope 351 is wound around the wire winding disc 331 in a clockwise first direction. The free end of the first rope 351 bypasses the reversing wheel 332 and is fixed to the sliding member 340. The second rope 352 is wound around the wire winding disc 331 in a counterclockwise second direction. The first direction and the second direction are opposite. The free end of the second rope 352 is fixed to the sliding member 340; the traction assembly 310 is connected to the wire winding disc 331, and the sliding member 340 is connected to the cabinet door 200. During the opening or closing process of the box door 100, the traction assembly 310 drives the wire winding disc 331 to rotate, and then drives the cabinet door 200 to move relative to the box door 100 through the sliding member 340.

[0113] Exemplarily, for the convenience of installation, in this embodiment, the sliding door assembly 320 can also be arranged on the base 120.

[0114] As Figure 5 and Figure 6 shown, the wire winding disc 331 and the reversing wheel 332 can be arranged on the base 120 at intervals in the width direction of the box door 100. Among them, one end in the width direction of the box door 100 is rotatably connected to the box body 110 via a hinge shaft. Then, the wire winding disc 331 can be located on the side closer to the hinge shaft relative to the reversing wheel 332.

[0115] For installation, a plurality of rotating shafts extending in the vertical direction are provided on the base 120. The wire winding disc 331 and the reversing wheel 332 are respectively arranged on these rotating shafts and can rotate around their respective rotating shafts. The sliding member 340 is arranged between the wire winding disc 331 and the reversing wheel 332. The sliding member 340 is connected to the cabinet door 200. During the movement of the sliding member 340, it can drive the cabinet door 200 to move in the width direction of the box door 100.

[0116] The first rope 351 is wound around the wire winding disc 331 in the first direction. Moreover, the free end of the first rope 351 extends out from the wire winding disc 331. After this free end bypasses the reversing wheel 332, it is fixedly connected to the sliding member 340. At this time, when the wire winding disc 331 rotates in the second direction, the first rope 351 can be wound onto the wire winding disc 331. At the same time, the free end of the first rope 351 will drive the sliding member 340 to move towards the reversing wheel 332.

[0117] The second rope 352 is wound around the winding disc 331 in the second direction, and the free end of the second rope 352 extends from the winding disc 331 and is directly fixedly connected to the sliding member 340. At this time, when the winding disc 331 rotates in the first direction, the second rope 352 can be wound onto the winding disc 331. At the same time, the free end of the second rope 352 will drive the sliding member 340 to move towards the winding disc 331.

[0118] Furthermore, when the door 100 of the box rotates from the closed position closing the storage space towards the open position opening the storage space, the traction assembly 310 can drive the winding disc 331 to rotate in the second direction. At this time, the first rope 351 is wound onto the winding disc 331 and drives the sliding member 340 to move towards the reversing wheel 332. When the door 100 of the box rotates from the open position opening the storage space towards the closed position closing the storage space, the traction assembly 310 can drive the winding disc 331 to rotate in the first direction. At this time, the second rope 352 is wound onto the winding disc 331 and drives the sliding member 340 to move towards the winding disc 331.

[0119] It can be understood that since the winding disc 331 and the reversing wheel 332 are arranged at intervals in the width direction of the door 100 of the box, by the above arrangement method, during the rotation of the door 100 of the box relative to the box body 110, the cabinet door 200 can be driven to move relative to the door 100 of the box in the width direction of the door 100 of the box.

[0120] Exemplarily, in a specific usage scenario, such as Figure 3 and Figure 4 shown, the first direction is the counterclockwise direction, and the second direction is the clockwise direction. At this time, the first rope 351 is wound around the winding disc 331 in the counterclockwise direction, and the second rope 352 is wound around the winding disc 331 in the clockwise direction.

[0121] Thus, in actual use, when the door 100 of the box rotates from the closed position closing the storage space towards the open position opening the storage space, the traction assembly 310 can drive the winding disc 331 to rotate in the clockwise direction. During the rotation of the winding disc 331 in the clockwise direction, the first rope 351 is wound onto the winding disc 331, the second rope 352 is unwound from the winding disc 331, and the sliding member 340 moves towards the reversing wheel 332, thereby driving the cabinet door 200 to move in the width direction of the door 100 of the box towards the direction away from the winding disc 331;

[0122] When the door 100 of the cabinet rotates from the open position for opening the storage space towards the closed position for opening the storage space, the traction assembly 310 can drive the winding disc 331 to rotate counterclockwise. During the process of the winding disc 331 rotating counterclockwise, the second rope 352 is wound onto the winding disc 331, the first rope 351 is unwound from the winding disc 331, and the sliding member 340 moves towards the winding disc 331, thereby driving the cabinet door 200 to move in the width direction of the door 100 towards the direction away from the reversing wheel 332.

[0123] In other embodiments, according to the installation position and usage requirements, the first direction can also be the clockwise direction and the second direction can be the counterclockwise direction.

[0124] As another specific implementation manner, the door 100 of the cabinet is rotatably connected to the cabinet body 110 via a hinge shaft, and moreover, the hinge shaft is fixedly connected to the cabinet body 110. The traction assembly 310 can include a gear set, the gear set includes a plurality of meshing gears, one gear in the gear set is fixedly arranged on the hinge shaft, this gear is coaxially arranged with the hinge shaft, several other gears in the gear set are rotatably arranged on the door 100 of the cabinet, and one gear in the gear set is fixedly arranged on the winding disc 331. During the process of the door 100 of the cabinet rotating relative to the cabinet body 110, the door 100 also rotates synchronously relative to the rotating shaft, and the gear set can drive the winding disc 331 to rotate in the first direction or the second direction. During the rotation of the winding disc 331, the sliding member 340 can be moved by pulling the first rope 351 or the second rope 352.

[0125] Furthermore, in the present embodiment, in the case where the traction assembly 310 includes the driving tooth portion 311, the driving tooth portion 311 is coaxially and fixedly connected to the winding disc 331. Of course, in other embodiments, in addition to the embodiment including the driving tooth portion 311, the traction assembly 310 can also adopt other forms.

[0126] Exemplarily, as Figure 7 shown, the driving tooth portion 311 includes a driving gear 3111 and a connecting shaft 3112. The winding disc 331 and the driving gear 3111 are coaxially connected via the connecting shaft 3112, and the winding disc 331 can rotate synchronously with the driving gear 3111.

[0127] As a kind of implementation manner, the winding disc 331 and the driving gear 3111 can be arranged on the connecting shaft 3112 through a keyway structure, or the driving tooth portion 311 can also include a positioning pin, and the positioning pin is inserted into the winding disc 331 and the driving gear 3111 in parallel with the extending direction of the connecting shaft 3112. Thus, under the connection action of the keyway structure or the positioning pin, the winding disc 331 can rotate synchronously with the driving gear 3111.

[0128] To facilitate the installation of the first rope 351 and the second rope 352, as Figure 7 shown, the winding disc 331 includes a first winding disc 3311 and a second winding disc 3312 arranged in a stacked manner. The first rope 351 is wound around the first winding disc 3311 in a first direction, and the second rope 352 is wound around the second winding disc 3312 in a second direction.

[0129] Exemplarily, as Figure 7 shown, the first winding disc 3311, the second winding disc 3312 and the driving gear 3111 are coaxially connected via a connecting shaft 3112. Thus, driven by the driving gear 3111, the first winding disc 3311 and the second winding disc 3312 can rotate synchronously.

[0130] In one embodiment, the first rope 351 and the second rope 352 are arranged at intervals along the height direction of the winding disc 331. The free end connection position of the first rope 351 on the sliding member 340 and the free end connection position of the second rope 352 on the sliding member 340 are at different heights.

[0131] It can be understood that the first winding disc 3311 and the second winding disc 3312 are arranged at intervals in the height direction of the connecting shaft 3112. At this time, the first rope 351 and the second rope 352 respectively connected to the first winding disc 3311 and the second winding disc 3312 can also be arranged at intervals in the axial direction of the connecting shaft 3112. By placing the first rope 351 and the second rope 352 at different heights, interference between the first rope 351 and the second rope 352 during storage or unwinding can be avoided.

[0132] In one embodiment, a first winding groove is provided on the outer periphery of the first winding disc 3311. The first winding disc 3311 is further provided with a first fixing groove. The first winding groove communicates with the first fixing groove through the notch of the first fixing groove. The fixed end of the first rope 351 is arranged in the first fixing groove, and the first rope 351 is wound around the first winding groove in a first direction; and / or,

[0133] A second winding groove is provided on the outer periphery of the second winding disc 3312. The second winding disc 3312 is further provided with a second fixing groove. The second winding groove communicates with the second fixing groove through the notch of the second fixing groove. The fixed end of the second rope 352 is arranged in the second fixing groove, and the second rope 352 is wound around the second winding groove in a second direction.

[0134] Exemplarily, as Figure 7As shown, the first winding disc 3311 is configured as a circular plate-like structure with a certain thickness. The outer sidewall of the first winding disc 3311 is provided with a first winding groove extending along its circumferential direction. Moreover, the first winding disc 3311 is also provided with a first fixing groove extending from the circumferential outer wall towards the radial interior. The notch of the first fixing groove communicates with the first fixing groove. The fixed end of the first rope 351 is arranged in the first fixing groove, and the first rope 351 is wound around the first winding groove in the first direction. For example, the first direction is the counterclockwise direction.

[0135] Optionally, in order to achieve fixation, the fixed end of the first rope 351 is provided with a first clamping block, which can be clamped in the first fixing groove. With the help of this first clamping block, it is possible to prevent the first rope 351 from falling off during the rotation of the first winding disc 3311.

[0136] Similarly, as Figure 7 shown, the second winding disc 3312 is configured as a circular plate-like structure with a certain thickness. The outer sidewall of the second winding disc 3312 is provided with a second winding groove extending along its circumferential direction. Moreover, the second winding disc 3312 is provided with a second fixing groove extending from the circumferential outer wall towards the radial interior. The notch of the second fixing groove communicates with the second fixing groove. The fixed end of the second rope 352 is arranged in the second fixing groove, and the second rope 352 is wound around the second winding groove in the second direction.

[0137] Optionally, in order to achieve fixation, the fixed end of the second rope 352 is provided with a second clamping block, which can be clamped in the second fixing groove. With the help of this second clamping block, it is possible to prevent the second rope 352 from falling off during the rotation of the second winding disc 3312.

[0138] In one embodiment, in order to effectively prevent the first rope 351 and the second rope 352 from interfering with each other and at the same time facilitate the storage of the first rope 351 and the second rope 352, as Figure 7 shown, the winding assembly further includes a first partition 3313, a second partition 3314 and a third partition 3315.

[0139] Among them, the first partition 3313, the first winding disc 3311, the second partition 3314, the second winding disc 3312 and the third partition 3315 are stacked. The first partition 3313 and the second partition 3314 can form a first annular accommodating groove for accommodating the first rope 351 on the outer periphery of the first winding disc 3311; the second partition 3314 and the third partition 3315 can form a second annular accommodating groove for accommodating the second rope 352 on the outer periphery of the second winding disc 3312.

[0140] Exemplarily, the first partition plate 3313, the first winding disc 3311, the second partition plate 3314, the second winding disc 3312, and the third partition plate 3315 are sequentially stacked in a fitting manner. At this time, the first winding disc 3311 is clamped between the first partition plate 3313 and the second partition plate 3314, and the second winding disc 3312 is clamped between the second partition plate 3314 and the third partition plate 3315.

[0141] In actual use, during the process of the driving gear 3111 driving the first winding disc 3311 and the second winding disc 3312 to rotate, the first rope 351 and the second rope 352 connected thereto can be respectively received in the first annular accommodating groove and the second annular accommodating groove.

[0142] Exemplarily, the first partition plate 3313, the second partition plate 3314, and the third partition plate 3315 can all have a circular plate-like structure with a certain thickness. Moreover, the dimensions of the first partition plate 3313 and the second partition plate 3314 in the radial direction are both larger than the dimension of the first partition plate 3313 in the radial direction, and the dimensions of the second partition plate 3314 and the third partition plate 3315 in the radial direction are both larger than the dimension of the second partition plate 3314 in the radial direction.

[0143] Furthermore, in order to ensure effective fixation among the first partition plate 3313, the first winding disc 3311, the second partition plate 3314, the second winding disc 3312, and the third partition plate 3315, the first partition plate 3313, the first winding disc 3311, the second partition plate 3314, the second winding disc 3312, and the third partition plate 3315 can be simultaneously arranged on the connecting shaft 3112.

[0144] Moreover, as Figure 7 shown, the winding assembly further includes a fastener 3316, and the fastener 3316 is sequentially inserted through the first partition plate 3313, the first winding disc 3311, the second partition plate 3314, the second winding disc 3312, and the third partition plate 3315.

[0145] Exemplarily, the fastener 3316 can be a positioning pin, and the fastener 3316 is sequentially inserted through the first partition plate 3313, the first winding disc 3311, the second partition plate 3314, the second winding disc 3312, and the third partition plate 3315 along the axial direction of the winding disc 331. Thus, during the process of the driving tooth portion 311 driving the winding disc 331 to rotate, the first partition plate 3313, the first winding disc 3311, the second partition plate 3314, the second winding disc 3312, and the third partition plate 3315 can rotate synchronously.

[0146] Optionally, the number of the fasteners 3316 can be two, and the two fasteners 3316 are spaced apart in the circumferential direction of the connecting shaft 3112.

[0147] In one embodiment, in order to effectively guide and limit the movement of the slider 340, as Figure 4 and Figure 5 shown, the door device further includes a guide rail 400, the guide rail 400 is disposed on the cabinet door 100, and the slider 340 is movably arranged on the guide rail 400.

[0148] Exemplarily, as Figure 5 shown, the guide rail 400 is fixedly arranged on the base 120, the guide rail 400 extends along the width direction of the cabinet door 100, the slider 340 is arranged in the guide rail 400, the slider 340 can move along the extending direction of the guide rail 400, and further, the cabinet door 200 is connected to the slider 340. Thus, when the slider 340 moves on the guide rail 400, the cabinet door 200 can also move relative to the cabinet door 100.

[0149] In one embodiment, as Figure 6 and Figure 8 shown, the slider 340 includes a sliding portion 341 and a connecting portion 342 which are connected to each other. The free ends of the first rope 351 and the second rope 352 are both connected to the sliding portion 341, the connecting portion 342 is connected to the cabinet door 200, the guide rail 400 is formed with a guiding space and a guiding groove 411 communicating with the guiding space, the sliding portion 341 is slidably arranged in the guiding space, the connecting portion 342 is partially exposed outside the guide rail 400 through the guiding groove 411, and slides along the length direction of the guiding groove 411.

[0150] Exemplarily, the interior of the guide rail 400 has a guiding space, the sliding portion 341 in the slider 340 is arranged in this guiding space, both the first rope 351 and the second rope 352 are connected to the sliding portion 341, and under the pulling of the first rope 351 or the second rope 352, the sliding portion 341 can move along the extending direction of the guide rail 400 in this guiding space.

[0151] As Figure 5 shown, the guide rail 400 is further provided with a guiding groove 411, one end of the connecting portion 342 is inserted into the guiding space through this guiding groove 411 and fixedly connected to the sliding portion 341, and the other end of the connecting portion 342 is connected to the cabinet door 200.

[0152] In actual use, during the process of the winding disc 331 rotating to drive the first rope 351 or the second rope 352 to move, the first rope 351 or the second rope 352 can pull the sliding portion 341 to move in this guiding space, and the connecting portion 342 can move synchronously with the guiding portion in the guiding groove 411, thereby driving the cabinet door 200 to move relative to the cabinet door 100.

[0153] In one embodiment, the guide rail 400 has opposite first and second sides, the first side is connected to the cabinet door 100, and the guide groove 411 is provided on the second side.

[0154] Exemplarily, as Figure 5 shown, the guide rail 400 includes an upper housing 410 and a lower housing 420. As Figure 9 and Figure 10 shown, the upper housing 410 and the lower housing 420 can be respectively formed by stamping and folding a metal sheet. The upper housing 410 and the lower housing 420 can be connected to each other to form a guide rail 400 of a certain length. A guiding space can be formed between the upper housing 410 and the lower housing 420. Moreover, the upper housing 410 is provided with a guide groove 411.

[0155] During actual installation, the lower housing 420 can be first set on the base 120, then the sliding member 340 is set on the upper housing 410, and then the upper housing 410 is connected to the top of the lower housing 420. At the same time, the connecting portion 342 of the sliding member 340 is inserted into the guide groove 411 of the upper housing 410. Finally, the connecting portion 342 is connected to the cabinet door 200.

[0156] Thus, the sliding member 340 can move in the guiding space formed between the upper housing 410 and the lower housing 420. Moreover, the connecting portion 342 of the sliding member 340 can extend to the outside of the guiding space to drive the cabinet door 200 to move.

[0157] In one embodiment, the sliding portion 341 includes a mounting surface and a guiding surface connected to the mounting surface. The mounting surface faces the winding disc 331 or the reversing wheel 332. The guiding surface is arranged in contact with the inner wall of the guiding space. The free ends of the first rope 351 and the second rope 352 are both fixed to the mounting surface.

[0158] Exemplarily, as Figure 8 and Figure 11 shown, in the width direction of the cabinet door 100, the mounting surface is located on the side of the sliding portion 341 facing the winding disc 331, and the guiding surface extends along the width direction of the cabinet door 100 and is located on the circumferential side of the sliding portion 341 facing the inner wall of the track.

[0159] During actual installation, after the sliding portion 341 is installed in the guiding space formed by the upper housing 410 and the lower housing 420, the guiding surface of the sliding portion 341 extending parallel to the width direction of the cabinet door 100 can be in contact with the inner walls of the upper housing 410 and the lower housing 420 in the guiding space. Moreover, the free ends of the first rope 351 and the second rope 352 are simultaneously connected to the mounting surface.

[0160] In other embodiments, in the width direction of the box door 100, the mounting surface may also be located on the side of the sliding portion 341 facing the reversing wheel 332, and the free ends of the first rope 351 and the second rope 352 are both fixedly connected to the mounting surface.

[0161] Alternatively, in the width direction of the box door 100, the number of mounting surfaces is two. In the width direction of the box door 100, the two mounting surfaces are respectively located on both sides of the sliding portion 341 facing the winding disc 331 and the reversing wheel 332, and the free ends of the first rope 351 and the second rope 352 may be respectively fixedly connected to the two mounting surfaces.

[0162] In one embodiment, as Figure 8 and Figure 11 shown, the mounting surface is provided with a mounting groove 3411. The height direction of the mounting groove 3411 is the same as the height direction of the winding disc 331. The free ends of the first rope 351 and the second rope 352 are both inserted into the mounting groove 3411, and the free end of the first rope 351 is located above the free end of the second rope 352.

[0163] It can be understood that by providing the mounting groove 3411 and making the free ends of the first rope 351 and the second rope 352 be located at different heights respectively, the fixation of the first rope 351 and the second rope 352 can be conveniently realized. At the same time, under the combined action of the first winding disc 3311 and the second winding disc 3312, it can be ensured that the first rope 351 and the second rope 352 are located at different positions in the height direction of the box door 100, further avoiding interference.

[0164] In order to be able to fix the free ends of the first rope 351 and the second rope 352 to the sliding portion 341, as Figure 11 shown, the mounting groove 3411 includes a through-hole section 3412 and a limiting hole section 3413. The extending direction of the limiting hole section 3413 is the same as the height direction of the mounting groove 3411. The extending direction of the limiting hole section 3413 is arranged at an angle with the extending direction of the through-hole section 3412. The opening degree of the through-hole section 3412 is larger than the opening degree of the limiting hole section 3413. The free ends of the first rope 351 and the second rope 352 can both move in the through-hole section 3412 and are limited in the limiting hole section 3413.

[0165] Exemplarily, the through-hole section 3412 may be perpendicular to the limiting hole section 3413. At this time, the through-hole section 3412 and the limiting hole section 3413 together form a T-shaped groove.

[0166] For the convenience of fixation, a first limiting block is provided at the free end of the first rope 351. The first limiting block can be integrally formed with the first rope 351, or the first limiting block can be sleeved on the free end of the first rope 351 and restricted to the free end of the first rope 351 when a knot is tied at the free end of the first rope 351. The dimension of the first limiting block in the radial direction is greater than the diameter of the first rope 351, and the dimension of the first limiting block in the radial direction is less than the opening degree of the limiting hole section 3413 and greater than the opening degree of the through hole section 3412.

[0167] During actual installation, the free end of the first rope 351 can be first connected to the sliding part 341 through the through hole section 3412, and the first limiting block is placed on the side close to the free end of the first rope 351 relative to the installation surface. Then, the first rope 351 is moved from the through hole section 3412 to the limiting hole section 3413, and the first limiting block is snapped into the sliding part 341. After that, the first rope 351 can be used to pull the sliding part 341.

[0168] Similarly, a second limiting block is provided at the free end of the second rope 352. The second limiting block can be integrally formed with the second rope 352, or the second limiting block can be sleeved on the free end of the second rope 352 and restricted to the free end of the second rope 352 when a knot is tied at the free end of the second rope 352. The dimension of the second limiting block in the radial direction is greater than the diameter of the second rope 352, and the dimension of the second limiting block in the radial direction is less than the opening degree of the limiting hole section 3413 and greater than the opening degree of the through hole section 3412.

[0169] During actual installation, the free end of the second rope 352 can be first connected to the sliding part 341 through the through hole section 3412, and the second limiting block is placed on the side close to the free end of the second rope 352 relative to the installation surface. Then, the second rope 352 is moved from the through hole section 3412 to the limiting hole section 3413, and the second limiting block is snapped into the sliding part 341. After that, the second rope 352 can be used to pull the sliding part 341.

[0170] It can be understood that the first rope 351 and the second rope 352 need to pull the sliding part 341 in opposite directions respectively. Therefore, the free ends of the first rope 351 and the second rope 352 are respectively located on both sides of the limiting hole section 3413, and the limiting blocks connected to the free ends of the first rope 351 and the second rope 352 are also respectively located on both sides of the limiting hole section 3413.

[0171] Furthermore, in order to enable the limiting block to be easily snapped into the installation groove 3411, as Figure 11As shown, a receiving groove 3414 is further provided on the sliding part 341. The receiving groove 3414 is located on the side of the mounting surface. For example, the receiving groove 3414 can be provided on the guiding surface of the sliding part 341. The receiving groove 3414 communicates with the limiting hole section 3413. Moreover, the opening degree of the receiving groove 3414 is larger than the size of the limiting block.

[0172] During actual installation, for example, when connecting the free end of the first rope 351 to the sliding part 341, the limiting block provided at the free end of the first rope 351 can be placed in the receiving groove 3414, then the first rope 351 is placed in the guiding through-hole section 3412, and finally the first rope 351 is moved to the limiting hole section 3413, so as to realize the installation of the first rope 351.

[0173] After the free ends of the first rope 351 and the second rope 352 are respectively placed in the limiting hole section 3413, the free ends of the first rope 351 and the second rope 352 can be respectively toggled up and down, so that the free ends of the first rope 351 and the second rope 352 are located at both ends of the limiting hole section 3413 in the height direction of the box door 100, so as to be located at different positions in the height direction of the box door 100.

[0174] It can be understood that by providing the receiving groove 3414 as above, it is more convenient to install the limiting block. Moreover, since the receiving groove 3414 can accommodate the first limiting block and the second limiting block, at this time, the opening degrees of the guiding through-hole section 3412 and the limiting hole section 3413 only need to be slightly larger than the diameters of the first rope 351 and the second rope 352.

[0175] Moreover, as Figure 4 shown, the winding disc 331 is rotatably provided at the top of the box door 100, and the reversing wheel 332 and the guide rail 400 are both fixed at the top of the box door 100. At this time, the base 120 is also correspondingly provided at the top of the box door 100. The winding disc 331 is rotatably provided on the base 120, and the reversing wheel 332 and the guide rail 400 are also provided on the base 120.

[0176] In other embodiments, according to actual installation requirements, the winding disc 331 can be correspondingly rotatably provided at the bottom of the box door 100, and the reversing wheel 332 and the guide rail 400 are both fixed at the bottom of the box door 100.

[0177] Or, in order to ensure the connection effect and ensure that the cabinet door 200 can move in the width direction of the box door 100, winding discs 331 are provided at both the top and the bottom of the box door 100, as well as other structures such as reversing wheels 332 and guide rails 400 corresponding to the winding discs 331.

[0178] In one embodiment, in order to realize the connection between the sliding member 340 and the cabinet door 200, as Figure 4 andFigure 5 As shown, the door body device further includes a connection component 500. The connection part 342 and the cabinet door 200 are connected together through the connection component 500. The connection component 500 is switchable between a combined state and a separated state. Among them, the connection component 500 includes a first connection member 510 provided on the connection part 342 and a second connection member 520 provided on the cabinet door 200. In the combined state, the first connection member 510 cooperates with the second connection member 520. In the separated state, the first connection member 510 is disengaged from the second connection member 520.

[0179] Exemplarily, the connection component 500 includes a first connection member 510 and a second connection member 520. Among them, the first connection member 510 can be connected to the sliding part 341. When the sliding part 341 moves along the width direction of the box door 100, the sliding part 341 can drive the first connection member 510 to move, thereby driving the cabinet door 200 to move. The second connection member 520 can be connected to the cabinet door 200, and the first connection member 510 and the second connection member 520 can cooperate with each other through structures such as a pin or a magnetic member.

[0180] In actual use, in the state where the first connection member 510 and the second connection member 520 cooperate with each other, the first connection member 510 and the second connection member 520 are combined with each other. At this time, the second connection member 520 can move synchronously with the first connection member 510, thereby driving the cabinet door 200 to move relative to the box door 100. In the state where the first connection member 510 and the second connection member 520 are disengaged, the first connection member 510 and the second connection member 520 are separated from each other. At this time, the cabinet door 200 can be detached from the outside of the box door 100.

[0181] Exemplarily, the connection part 342 of the sliding member 340 can be connected to the first connection member 510 in a snap - connection manner. For example, the first connection member 510 is provided with a snap - connection groove extending along the height direction or the thickness direction of the box door 100, and the connection part 342 can be directly snapped into the snap - connection groove. Thus, when the sliding member 340 moves along the width direction of the box door 100, it can drive the first connection member 510 to move, and moreover, the first connection member 510 can also be easily separated from the sliding member 340.

[0182] Exemplarily, in order to save installation space, as Figure 5 and Figure 12 shown, the second connection member 520 includes a connection plate 521 and a cooperation plate 522 connected to the connection plate 521 at an angle. The connection plate 521 is connected to the inner side surface of the cabinet door 200, and the cooperation plate 522 is detachably connected to the first connection member 510.

[0183] Exemplarily, the connecting plate 521 extends along the thickness direction of the cabinet door 100, and the mating plate 522 extends along the height direction of the cabinet door 100. The connecting plate 521 and the mating plate 522 are perpendicularly connected to each other, and the two together form an L-shaped plate. The connecting plate 521 can be connected to the first connecting member 510 through the cooperation of structures such as pins or magnetic members, and the side of the mating plate 522 facing away from the cabinet door 100 is fixedly connected to the cabinet door 200 through structures such as bolts.

[0184] Thus, through the above setting method, an effective connection between the sliding member 340 and the cabinet door 200 can be achieved. Moreover, by constructing the second connecting member 520 into an L-shaped structure, space can be saved.

[0185] Furthermore, in order to facilitate the installation of the second connecting member 520, as Figure 4 shown, an avoidance groove 210 is provided on the inner side surface of the cabinet door 200, and the connecting plate 521 is disposed in the avoidance groove 210.

[0186] Exemplarily, in the thickness direction of the cabinet door 200, an avoidance groove 210 is provided on the inner side surface of the cabinet door 200 facing the cabinet door 100. The avoidance groove 210 is recessed into the surface of the cabinet door 200, and the avoidance groove 210 can also extend along the height direction of the cabinet door 200. The mating plate 522 in the second connecting member 520 is fixed in the avoidance groove 210 by means of structures such as bolts.

[0187] In practice, by providing the avoidance groove 210 on the cabinet door 200, sufficient installation space can be reserved for the connection between the second connecting member 520 and the cabinet door 200. Thus, when the cabinet door 200 is disposed outside the cabinet door 100, the cabinet door 200 can better fit the cabinet door 100, so as to reduce the gap between the cabinet door 200 and the cabinet door 100 and achieve a better installation effect.

[0188] Furthermore, in order to prevent external sundries from entering the sliding door mechanism 300 and the guide rail 400, as Figure 3 and Figure 13 shown, the door body device further includes a protective shell 130. The protective shell 130 covers the top of the base 120, and an accommodation space can be formed between the protective shell 130 and the base 120. The sliding door mechanism 300 and the guide rail 400 are both disposed in the accommodation space.

[0189] Exemplarily, as Figure 14 shown, the protective shell 130 can be made by stamping a sheet metal part, or can be made by injection molding using a plastic material. The protective shell 130 is provided with a through groove 131, and the position and size of the through groove 131 correspond to the position and size of the guiding groove 411 in the guide rail 400.

[0190] In actual use, the protective case 130 can be fixedly connected to the base 120 by means of structures such as bolts. The connecting portion 342 of the sliding member 340 can extend to the outside of the accommodating space through the through groove 131 on the protective case 130, so as to be connected to the connecting assembly 500. Moreover, since the through groove 131 corresponds to the guiding groove 411, it can be ensured that the sliding member 340 can move along the width direction of the box door 100, thereby driving the cabinet door 200 to move.

[0191] Furthermore, in order to achieve the sliding connection between the cabinet door 200 and the box door 100, as Figure 3 and Figure 13 shown, the door body device further includes a sliding mechanism 600. The cabinet door 200 is slidably disposed outside the box door 100 through the sliding mechanism 600.

[0192] Exemplarily, the sliding mechanism 600 can be a structure such as a linear slide rail. For example, the sliding mechanism 600 can extend along the width direction of the box door 100, so that the cabinet door 200 can move along the width direction of the box door 100.

[0193] In one embodiment, as Figure 12 and Figure 15 shown, the sliding mechanism 600 includes a pulley assembly 610 and a slide rail assembly 620. One of the pulley assembly 610 and the slide rail assembly 620 is disposed on the box door 100, and the other is disposed on the cabinet door 200. The pulley assembly 610 includes a pulley 611. The slide rail assembly 620 is provided with a linear slide cavity. The rotation axis of the pulley 611 is perpendicular to the axis of the linear slide cavity, so that the pulley 611 and the linear slide cavity cooperate to form a rolling connection.

[0194] In this embodiment, as Figure 13 shown, the pulley assembly 610 is disposed on the cabinet door 200, and the slide rail assembly 620 is disposed on the box door 100.

[0195] More specifically, the pulley 611 in the pulley assembly 610 can be connected to the cabinet door 200. The slide rail assembly 620 is disposed at the top of the box door 100. The linear slide cavity in the slide rail assembly 620 extends along the width direction of the box door 100. The pulley 611 has a rotation axis, and this rotation axis extends along the thickness direction of the box door 100. At this time, the rotation axis is perpendicular to the axis of the linear slide cavity. The pulley 611 is disposed in the linear slide cavity, and the pulley 611 can roll along the axis direction of the linear slide cavity.

[0196] Thus, through the above setting method, by using the cooperation structure of the pulley 611 and the slide rail, the cabinet door 200 can be slidably disposed outside the box door 100, and moreover, the cabinet door 200 can move in the width direction of the box door 100.

[0197] Of course, in other embodiments, according to the usage requirements, the pulley assembly 610 can also be arranged on the door 100, and the slide rail assembly 620 can be arranged on the cabinet door 200.

[0198] In one embodiment, as Figure 12 and Figure 15 shown, the slide rail assembly 620 includes a rail member 621 and a first mounting member. A linear sliding cavity is formed on the rail member 621; a first mounting member is arranged at a position of the rail member 621 other than the linear sliding cavity, and the first mounting member is connected to the door 100.

[0199] Exemplarily, the rail member 621 can be fixedly arranged on the top of the door 100, the rail member 621 extends along the width direction of the door 100, and the rail member 621 can be configured as a U-shaped groove, and the opening of the U-shaped groove faces away from the cabinet door 200 in the thickness direction of the door 100.

[0200] Specifically, the rail member 621 can include a vertical plate and two horizontal plates. The vertical plate and the two horizontal plates both extend along the width direction of the door 100. The two horizontal plates are respectively vertically connected to the opposite sides of the vertical plate in the height direction of the door 100. The linear sliding cavity is located between the two horizontal plates. At the same time, the pulley 611 in the pulley assembly 610 is also arranged between the two horizontal plates.

[0201] The first mounting member can be a structure such as a bolt, and the rail member 621 can be fixed on the top of the door 100 by means of the first mounting member.

[0202] Optionally, extension plates are respectively arranged on one sides of the two horizontal plates away from the vertical plate, and the two extension plates extend towards each other. Thus, after the pulley 611 is placed in the linear sliding cavity, the two extension plates and the vertical plate can limit the pulley 611 in the thickness direction of the door 100 to prevent the pulley 611 from falling off the linear sliding cavity.

[0203] In one embodiment, as Figure 12 and Figure 15 shown, the pulley assembly 610 further includes a mounting seat 612, a pin shaft 613 and a second mounting member; a second mounting member is arranged on the mounting seat 612, and the second mounting member is connected to the cabinet door 200; a shaft hole is arranged on the mounting seat 612, the pin shaft 613 is rotatably inserted through the shaft hole, the pin shaft 613 is inserted through the center of the pulley 611, so that the pulley 611 is rotatably arranged on the mounting seat 612 through the pin shaft 613, and the pin shaft 613 is the rotation shaft of the pulley 611.

[0204] Exemplarily, the second mounting member may be a structure such as a bolt. The mounting seat 612 can be fixedly connected to the cabinet door 200 by means of the second mounting member. The mounting seat 612 is further provided with a shaft hole, and the pin shaft 613 can extend in the thickness direction of the box door 100 and be inserted into the shaft hole. Moreover, the pin shaft 613 is inserted into the pulley 611, and the pulley 611 can rotate around the pin shaft 613.

[0205] Thus, through the above setting method, the effective installation of the pulley 611 can be achieved.

[0206] Further, the pin shaft 613 is rotatably inserted through the shaft hole, that is, the pin shaft 613 can rotate in the shaft hole. At this time, in order to position the pin shaft 613, snap rings can be respectively arranged on both sides of the shaft hole on the pin shaft 613. Through these two snap rings, during the rotation of the pin shaft 613 relative to the shaft hole, the pin shaft 613 is prevented from falling out of the shaft hole in the axial direction of the shaft hole. In this setting method, the roller can be fixedly connected to the pin shaft 613 or rotatably connected to the pin shaft 613.

[0207] Alternatively, the pin shaft 613 can also be fixedly inserted into the shaft hole. At this time, the pin shaft 613 cannot move in the shaft hole. Correspondingly, in this setting method, the roller needs to be rotatably connected to the pin shaft 613.
