The first slider and the second slider can slide synchronously along the guide rails driven by the connecting member, and the sliding directions are opposite. The first slider is connected to the box body through a traction mechanism and the box body transmission, and the second slider is connected to the door panel set on the outside of the box door, so that when the box door rotates, the box body drives the two sliders to slide relative to each other through the traction mechanism and the connecting member to drive the door panel to slide relative to the box door, so that the door panel can avoid obstacles on both sides during the process of rotating the box door.

[0057] The following combines Figures 1 to 5 to describe the sliding door device, door body assembly, and refrigeration device of the present application. The sliding door device and door body assembly in the present application can be applied to the box door or cabinet door of household appliances, such as the box door of a refrigerator. However, it should be understood that the door panel mechanism and door body assembly of the present application can also be applied to dishwashers, washing machines, or any other suitable devices. The refrigeration device in the present application is, for example, applied to a refrigerator. However, it should be understood that the refrigeration device of the present application can also be applied to a freezer or any other suitable device.

[0058] In one embodiment of the present application, as Figure 1 and Figure 2As shown, the sliding door device is applied to a refrigeration device, and the refrigeration device includes a box body 1, a box door 2 and a door panel 21. The box door 2 is rotatably connected to the box body 1, and a door panel 21 is provided on the outer side of the box door 2 along which a sliding door panel 21 is provided; the sliding door device includes: at least two active sliding door mechanisms, each of which includes: a first base, a first slider 715, a traction mechanism, a second slider 709 and a connecting member; the first base is used to be arranged on the box door 2, and a first guide rail 710 is formed on one side of the first base, and a second guide rail 705 is formed on the other side; the first slider 715 is slidably arranged on the first guide rail 710, The first slider 715 is connected to the box body 1 through a traction mechanism; the second slider 709 is slidably arranged on the second guide rail 705 for connecting to the door panel 21; the two ends of the connecting piece are respectively connected to the first slider 715 and the second slider 709; the connecting rod 9 is connected to the second sliders 709 in all the active sliding door mechanisms, so that when any first slider 715 moves along the corresponding first guide rail 710 driven by the traction mechanism, the first slider 715 drives all the second sliders 709 to move in the opposite direction on the corresponding second guide rail 705 through the connecting piece and the connecting rod 9.

[0059] It is understandable that if Figures 1 to 3 As shown, the active sliding door mechanism of this embodiment can be arranged on the box door 2, the first slider 715 is connected to the box body 1 through a traction mechanism, and the second slider 709 is used to be slidably connected to the door panel 21 arranged on the outside of the box door 2, so that when the box door 2 rotates, the two sliders slide relative to each other to drive the door panel 21 to slide relative to the box door 2, so that the door panel 21 can avoid obstacles on both sides when the box door 2 is turned on and off.

[0060] Specifically, the first base of this embodiment can be set on the box door 2. The connecting member can be a connecting member such as a traction rope, a transmission belt, etc., and the two ends of the connecting member are respectively connected to the first slider 715 and the second slider 709, so that the first slider 715 can drive the second slider 709 to move synchronously, thereby driving the door panel 21 to slide relative to the box door 2.

[0061] By properly setting the extending direction of the connecting member, the first slider 715 and the second slider 709 move in opposite directions, so as to drive the door panel 21 to avoid obstacles.

[0062] Specifically, during the process of the box door 2 rotating outward and opening relative to the box body 1, the box body 1 drives the first slider 715 to slide towards the first hinge 4 through the traction mechanism. At the same time, the first slider 715 drives the second slider 709 to slide in the opposite direction (i.e., away from the first hinge 4) through the connecting member, thereby preventing the door panel 21 from interfering with obstacles on the outside. During the process of the box door 2 rotating and closing towards one side of the box body 1, the box body 1 drives the first slider 715 to slide away from the first hinge 4 through the traction mechanism. At the same time, the first slider 715 drives the second slider 709 to slide in the opposite direction (i.e., towards the first hinge 4) through the connecting member, thereby preventing the door panel 21 from interfering with obstacles after closing.

[0063] At the same time, by providing at least two active sliding door mechanisms, the first sliders 715 of the two active sliding door mechanisms can be connected to different positions of the box door 2 or the box body 1, and the second sliders 709 of the two active sliding door mechanisms can be connected to different positions of the door panel 21. The connecting rod 9 is connected to the second sliders 709 in all the active sliding door mechanisms, enabling the second sliders 709 in all the active sliding door mechanisms to move synchronously, so as to improve the stability of the door panel 21 during the sliding process relative to the box door 2.

[0064] According to the sliding door device of the present application, by providing at least two active sliding door mechanisms, the first guide rail 710 and the second guide rail 705 are provided on both sides of the first base of the active sliding door mechanism. The first slider 715 and the second slider 709 are respectively slidably provided on the first guide rail 710 and the second guide rail 705. The first slider 715 and the second slider 709 can synchronously slide along the corresponding guide rails under the drive of the connecting member, and the sliding directions are opposite. The first slider 715 is drivingly connected to the box body 1 through the traction mechanism, and the second slider 709 is connected to the door panel 21 provided on the outside of the box door 2. So that when the box door 2 rotates, the box body 1 drives the two sliders to slide relative to each other through the traction mechanism and the connecting member, so as to drive the door panel 21 to slide relative to the box door 2, enabling the door panel 21 to avoid obstacles on both sides during the process of the box door 2 rotating and opening / closing. At the same time, by connecting the connecting rod 9 to the second sliders 709 in all the active sliding door mechanisms, the sliding of all the second sliders 709 is more synchronous, thereby making the sliding of the door panel 21 more stable.

[0065] It should be noted that in practical applications, the designs of the first slider 715 and the second slider 709, as well as other sliders in the present application, can be flexible and variable to adapt to different working scenarios and performance requirements. They are not limited to specific shapes, sizes, or materials, but can be customized and optimized according to specific needs.

[0066] From a material perspective, the first slider 715, the second slider 709, and other sliders in the present application can be made of materials with high wear resistance, low friction coefficient, and good stability, such as metal alloys, engineering plastics, or special lubricating materials. The selection of these materials aims to improve the durability of the sliders, reduce wear and noise during sliding, and ensure smooth sliding.

[0067] In terms of structural design, the first slider 715, the second slider 709, and other sliders in the present application can adopt various forms of guide rail contact surfaces, such as plane contact, ball contact, or sliding bearing contact, etc. These different contact methods have their own advantages and disadvantages. For example, ball contact can reduce friction and wear, but the cost is relatively high; while plane contact has a simple structure, but may require more frequent lubrication and maintenance. Therefore, when making a choice, factors such as usage conditions, cost-effectiveness, and maintenance convenience should be comprehensively considered.

[0068] Optionally, in an embodiment of the present application, as Figure 1 and Figure 2 shown, there are two active sliding door mechanisms, and the two active sliding door mechanisms are arranged correspondingly up and down. Both ends of the connecting rod 9 are respectively connected to the second sliders 709 in the two active sliding door mechanisms.

[0069] In this embodiment, by arranging two active sliding door mechanisms up and down, the two active sliding door mechanisms can be arranged at different positions of the box door 2 along the height direction of the box door 2. The connecting rod 9 is arranged vertically, and both ends of the connecting rod 9 are respectively connected to the second sliders 709 in the two active sliding door mechanisms, so that the second sliders 709 of the two active sliding door mechanisms can move synchronously, so as to improve the stability during the sliding process of the door panel 21 relative to the box door 2.

[0070] Specifically, in an embodiment of the present application, both ends of the connecting rod 9 are respectively inserted into the second sliders 709 in the two active sliding door mechanisms.

[0071] In this embodiment, both ends of the connecting rod 9 are respectively inserted into the second sliders 709 of the active sliding door mechanism, which is convenient for disassembling and assembling the connecting rod 9 and the second sliders 709 of the active sliding door mechanism.

[0072] Optionally, in some embodiments of the present application, as Figure 1 and Figure 2 shown, each active sliding door mechanism further includes: a first ball support member and a second ball support member. The first ball support member is slidably internally connected to the corresponding first guide rail 710, and the first slider 715 is slidably internally connected to the corresponding first ball support member. The second ball support member is slidably internally connected to the corresponding second guide rail 705, and the second slider 709 is slidably internally connected to the corresponding second ball support member.

[0073] In this embodiment, by providing a first ball support between the first slider 715 and the first guide rail 710, the first ball support can slide along the first guide rail 710 as the first slider 715 slides, so as to remain between the first slider 715 and the first guide rail 710. The first ball support can convert at least part of the friction between the first slider 715 and the first guide rail 710 into rolling friction, making the sliding of the first slider 715 smoother; similarly, the second ball support is slidably provided between the second slider 709 and the second guide rail 705, and can convert at least part of the friction between the second slider 709 and the second guide rail 705 into rolling friction, making the sliding of the second slider 709 also smoother, thereby making the relative sliding between the box door 2 and the door panel 21 smoother.

[0074] Specifically, in one embodiment of the present application, as Figure 1 and Figure 2 shown, each first ball support includes: a first ball (not shown in the figure) and a first support frame 714; each second ball support includes: a second ball (not shown in the figure) and a second support frame 707. A first limiting notch is formed on the first support frame 714, the first ball is rotatably disposed in the corresponding first limiting notch, one side of the first ball abuts against the corresponding first guide rail 710, and the other side of the first ball passes through the corresponding first limiting notch and abuts against the corresponding first slider 715. A second limiting notch is formed on the second support frame 707, the second ball is rotatably disposed in the corresponding second limiting notch, one side of the second ball abuts against the corresponding second guide rail 705, and the other side of the second ball passes through the corresponding second limiting notch and abuts against the corresponding second slider 709.

[0075] In this embodiment, a first support frame 714 is provided between the first slider 715 and the first guide rail 710. A first limiting notch is formed on the first support frame 714 to provide a first ball for limiting the first ball, so as to prevent the first ball from rolling and shifting, making the sliding of the first slider 715 more stable and reliable. The two sides of the first ball are respectively in contact with the first guide rail 710 and the first slider 715. When the first slider 715 rolls relative to the first guide rail 710, the first ball can roll to convert at least part of the friction received by the first slider 715 into rolling friction, making the sliding of the first slider 715 smoother. Similarly, a second support frame 707 is provided between the second slider 709 and the second guide rail 705. A second limiting notch is formed on the second support frame 707 to provide a second ball for limiting the second ball, so as to prevent the second ball from rolling and shifting, making the sliding of the second slider 709 more stable and reliable. The two sides of the second ball are respectively in contact with the second guide rail 705 and the second slider 709. When the second slider 709 rolls relative to the second guide rail 705, the second ball can roll to convert at least part of the friction received by the second slider 709 into rolling friction, making the sliding of the second slider 709 smoother.

[0076] Optionally, a plurality of first balls and second balls are provided.

[0077] Optionally, in an embodiment of the present application, as Figure 1 and Figure 2 shown, the first support frame 714 is provided with first limiting notches on both sides opposite to the first guide rail 710. There are two groups of first balls, and the two groups of first balls are respectively arranged in the first limiting notches on both sides to rollably abut against both sides of the corresponding first slider 715. The second support frame 707 is provided with second limiting notches on both sides opposite to the second guide rail 705. There are two groups of second balls, and the two groups of second balls are respectively arranged in the second limiting notches on both sides to rollably abut against both sides of the corresponding second slider 709.

[0078] In this embodiment, by arranging the first limiting notch on both sides of the first slider 715, the two groups of first balls are respectively rotatably arranged on both sides of the first slider 715 and are respectively in contact with the first slider 715 and the first guide rail 710. While converting at least part of the friction received by the first slider 715 into rolling friction, the forces on both sides of the first slider 715 can be made more balanced, making the first slider 715 slide more stably and smoothly relative to the first guide rail 710. Similarly, the two groups of second balls are also respectively rotatably arranged on both sides of the second slider 709. While converting at least part of the friction received by the second slider 709 into rolling friction, the forces on both sides of the second slider 709 can be made more balanced, making the second slider 709 slide more stably and smoothly relative to the second guide rail 705.

[0079] Optionally, in an embodiment of the present application, as Figure 1 and Figure 3 shown, there are two active sliding door mechanisms, namely the first active sliding door mechanism 7 and the second active sliding door mechanism 6; both ends of the connecting rod 9 are respectively connected to the second slider 709 of the first active sliding door mechanism 7 and the second slider 709 of the second active sliding door mechanism 6.

[0080] In this embodiment, by setting the first active sliding door mechanism 7 and the second active sliding door mechanism 6, the first active sliding door mechanism 7 and the second active sliding door mechanism 6 can be respectively arranged at different positions between the box door 2 and the door panel 21, so as to pull the door panel 21 to slide relative to the box door 2 at different positions, making the sliding of the door panel 21 relative to the box door 2 more stable and reliable. At the same time, by setting the connecting rod 9 to connect the second slider 709 of the first active sliding door mechanism 7 and the second slider 709 of the second active sliding door mechanism 6, the synchronism of the sliding of the second sliders 709 of the two active sliding door mechanisms is improved, so that the sliding of the door panel 21 is more stable and reliable.

[0081] In an embodiment of the present application, as Figure 1 and Figure 2 shown, the connecting piece includes: a first connecting piece 706 and a second connecting piece 712. The first connecting piece 706 bypasses one end of the first base, and both ends are respectively connected to one end of the first slider 715 and the second slider 709; the second connecting piece 712 bypasses the other end of the first base, and both ends are respectively connected to the other end of the first slider 715 and the second slider 709.

[0082] In this embodiment, by connecting the first connecting piece 706 around one end of the first base to the first slider 715 and the second slider 709 respectively, when the first slider 715 slides away from this end of the first base under the drive of the box body 1 and the traction mechanism, the first slider 715 drives the second slider 709 to slide towards this end of the first base through the first connecting piece 706; at the same time, by connecting the second connecting piece 712 around the other end of the first base to the first slider 715 and the second slider 709 respectively, when the first slider 715 slides away from the other end of the first base under the drive of the box body 1 and the traction mechanism, the first slider 715 drives the second slider 709 to slide towards the other end of the first base through the second connecting piece 712, so as to realize that when the first slider 715 slides towards both ends of the first base respectively, it can drive the second slider 709 to slide in the opposite direction to the first slider 715, and further enable the door panel 21 to slide relative to the box door 2 with the rotation of the box door 2 when the box door 2 is opened and closed, so as to avoid interference with obstacles and affect the opening and closing of the box door 2.

[0083] In an embodiment of the present application, as Figure 1 and Figure 2As shown, the active sliding door mechanism further includes: a first fixed seat 704 and a second fixed seat 711. The first fixed seat 704 is connected to one end of the first base, and a first limiting groove is formed. The two ends of the first limiting groove are docked with one ends of the first guide rail 710 and the second guide rail 705. A part of the first connecting member 706 is slidably disposed in the first limiting groove; the second fixed seat 711 is connected to the other end of the first base, and a second limiting groove is formed. The two ends of the second limiting groove are docked with the other ends of the first guide rail 710 and the second guide rail 705. A part of the second connecting member 712 is slidably disposed in the second limiting groove.

[0084] In this embodiment, by respectively disposing the first fixed seat 704 and the second fixed seat 711 at the two ends of the first base, the first fixed seat 704 and the second fixed seat 711 respectively form a first limiting groove and a second limiting groove that are docked with the first guide rail 710 and the second guide rail 705, respectively limiting and guiding the positions of the first connecting member 706 and the second connecting member 712, making the sliding of the first connecting member 706 and the second connecting member 712 smoother and more stable.

[0085] Specifically, in an embodiment of the present application, the first fixed seat 704 is provided with a fixing hole. The active sliding door mechanism further includes a fixing member, and the fixing member passes through the fixing hole to connect with an external structure.

[0086] In this embodiment, by providing a fixing hole on the first fixed seat 704 and passing the fixing member through the fixing hole and fixing it in the external structure, so as to fix the first fixed seat 704 in the external structure, thereby fixing the base on the external structure (such as the box door 2).

[0087] It can be understood that the second fixed seat 711 is provided with a fixing hole. The active sliding door mechanism further includes a fixing member, and the fixing member passes through the fixing hole to connect with an external structure.

[0088] In this embodiment, by providing a fixing hole on the second fixed seat 711 and passing the fixing member through the fixing hole and fixing it in the external structure, so as to fix the second fixed seat 711 in the external structure, thereby fixing the base on the external structure (such as the box door 2).

[0089] In an embodiment of another aspect of the present application, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, a door assembly is provided, including: a box door 2, a door panel 21, and a sliding door device provided in any of the above embodiments. The box door 2 is rotatably connected to the box body 1 and is adapted to open or close the storage space of the box body 1. The door panel 21 is slidably disposed outside the box door 2; the sliding door device is disposed on the box door 2, and the first slider 715 of all the active sliding door mechanisms is drivingly connected to the box body 1 through a traction mechanism, and the second slider 709 of all the active sliding door mechanisms is connected to the door panel 21. During the opening or closing process of the box door 2, the corresponding first slider 715 and the second slider 709 move in opposite directions to drive the door panel 21 to move relative to the width direction of the box door 2.

[0090] It can be understood that the width direction of the box door 2 is parallel to the plane where the box door 2 is located and perpendicular to the rotation axis of the box door 2, so that the door panel 21 can move away from or close to the rotation axis of the box door 2 (as shown by the double-headed arrow in Figure 4 ). It should be noted that for the parallel and perpendicular relationships in this application, the installation errors between various components need to be considered, and an error of plus or minus 10° should be understood as the scope protected by the patent.

[0091] In this embodiment, during the process of the box door 2 rotating and opening outwardly from the box body 1 (as shown by the arc arrow in Figure 4 ), the first slider 715 slides in the direction close to the first hinge 4 under the drive of the box body 1 and the traction mechanism. The first slider 715 drives the second slider 709 to slide in the direction away from the first hinge 4 through a connecting member, thereby driving the door panel 21 to slide in the direction away from the first hinge 4, and further avoiding interference between the door panel 21 and external obstacles. Similarly, during the process of the box door 2 rotating and closing to one side of the box body 1, the active sliding door mechanism drives the door panel 21 to slide in the direction close to the first hinge 4, thereby avoiding interference between the door panel 21 and obstacles after closing.

[0092] According to the door assembly of the embodiment of the present application, a sliding door device is provided on the box door 2. The sliding door device includes at least two active sliding door mechanisms, and each active sliding door mechanism is respectively connected to the box door 2 and the door panel 21, so as to drive the door panel 21 to slide relative to the width direction of the box door 2 during the process of the box door 2 rotating and opening or closing relative to the box body 1, so that the door panel 21 can avoid obstacles such as side walls and objects during the closing or opening process of the box door 2.

[0093] It can be understood that if the sliding door device has the beneficial effects of the above embodiments, the door assembly correspondingly has the beneficial effects of the above embodiments. The specific implementation manners can refer to the above embodiments, and details will not be described in this application.

[0094] In an embodiment of the present application, as shown in Figure 1 and Figure 2As shown, each traction mechanism includes a traction rod 702, a first rotating shaft fixing seat 713, and a second rotating shaft fixing seat 701. The first rotating shaft fixing seat 713 is connected to the corresponding first slider 715, and the second rotating shaft fixing seat 701 is used to be connected to the box body 1. One end of the traction rod 702 is rotatably connected to the corresponding first rotating shaft fixing seat 713, and the other end of the traction rod 702 is rotatably connected to the corresponding second rotating shaft fixing seat 701.

[0095] In this embodiment, by respectively fixing the first rotating shaft fixing seat 713 and the second rotating shaft fixing seat 701 on the first slider 715 and the box body 1, and connecting them through the traction rod 702 between the first rotating shaft fixing seat 713 and the second rotating shaft fixing seat 701, the distance between the first slider 715 and the second rotating shaft fixing seat 701 is always kept unchanged. When the box door 2 rotates relative to the box body 1, the angle between the box body 1 and the box door 2 changes. Thus, through the transmission connection of the traction rod 702, the first rotating shaft fixing seat 713, and the second rotating shaft fixing seat 701, the first slider 715 is pulled, so that the first slider 715 slides on the base, and drives the second slider 709 to slide to realize the movement of the door panel 21 relative to the box door 2.

[0096] Specifically, one end of the traction rod 702 and the first rotating shaft fixing seat 713 are rotatably connected through a pin shaft 703, and the other end and the second rotating shaft fixing seat 701 are rotatably connected through another pin shaft 703.

[0097] Optionally, in an embodiment of the present application, two active sliding door mechanisms can be respectively arranged at the top and bottom ends of the box door 2 so that the traction mechanism can be connected to the box body 1.

[0098] In an embodiment of the present application, as Figure 3 and Figure 5 shown, the door body assembly further includes: a driven sliding door mechanism 8, and the driven sliding door mechanism 8 includes a second base 817 and a third slider 813; a third guide rail is formed on the second base 817, and the third slider 813 is slidably arranged on the third guide rail, and the third slider 813 is connected to the door panel 21.

[0099] In this embodiment, by arranging the driven sliding door mechanism 8 on the box door 2, the driven sliding door mechanism 8 has a second base 817, a third guide rail is provided on the second base 817 and a third slider 813 that can slide along the third guide rail, and the third slider 813 is connected to the door panel 21. The third slider 813 can slide along with the door panel 21 when the door panel 21 slides relative to the box door 2, playing a role of supporting and assisting the sliding of the door panel 21, so that the door panel 21 slides more smoothly relative to the box door 2. At the same time, the driven sliding door mechanism 8 can cooperate with the active sliding door mechanism to limit the movement direction of the door panel 21, reduce the shaking generated during the sliding of the door panel 21, and make the sliding more stable.

[0100] Optionally, there may be multiple driven sliding door mechanisms 8. Among them, some of the driven sliding door mechanisms 8 may be coaxially arranged with the active sliding door mechanism on the box door 2; another part of the driven sliding door mechanisms 8 are non-coaxially arranged with the active sliding door mechanism on the box door 2.

[0101] Specifically, the coaxial arrangement of the driven sliding door mechanism 8 and the active sliding door mechanism 7 means sharing the same center line or axis, which helps to ensure that the door panel 21 can maintain a stable linear motion during sliding, reducing the possibility of deviation or swing. The coaxial arrangement is used in situations where precise control of the motion direction or maintaining the relative positional relationship between components is required.

[0102] The non-coaxial arrangement of the driven sliding door mechanism 8 and the active sliding door mechanism 7 means that they do not share the same center line or axis. This configuration is used to provide additional support, stability, or prevent the door panel 21 from deflecting around the sliding direction during sliding. The non-coaxial arrangement is used in situations where it is necessary to disperse forces, increase stability, or achieve complex motion trajectories.

[0103] In some embodiments, as Figure 1 , Figure 2 and Figure 5 shown, a first connecting block 814 is provided on the third slider 813, and a first slot for the door panel 21 to be hung is provided on the first connecting block 814. Second connecting blocks 708 are provided on the second sliders 709 of all the active sliding door mechanisms. The connecting rod 9 is connected to the connecting blocks of all the second sliders 709, and a second slot for the door panel 21 to be hung is formed on at least one of the connecting rod 9 and each second connecting block 708.

[0104] In this embodiment, by providing the first connecting block 814 on the third slider 813 and providing the first slot for the door panel 21 to be hung on the first connecting block 814, it is convenient for the user to install the door panel 21 on the first connecting block 814, so that the third slider 813 can slide with the door panel 21 to play a supporting and auxiliary role; similarly, second connecting blocks 708 are provided on the second sliders 709 of all the active sliding door mechanisms. The second connecting block 708 is used to connect with the connecting rod 9. At the same time, a second slot can be provided on either or both of the second connecting block 708 and the connecting rod 9, which is convenient for the user to connect the door panel 21 through the connecting rod 9 or the second connecting block 708 or both of them and the second slider 709, so that the door panel 21 can slide relative to the box door 2 under the drive of the second slider 709.

[0105] In an embodiment of another aspect of the present application, as Figure 3 and Figure 4 shown, a refrigeration device is provided, including: a box body 1 and a door body assembly as provided in any of the above embodiments. Among them, the box body 1 forms a storage space, and the box door 2 is rotatably connected to the box body 1 and is adapted to open or close the storage space.

[0106] In this embodiment, the door body assembly includes: a box door 2, a door panel 21, and a sliding door device. The sliding door device includes at least two active sliding door mechanisms, which are arranged on the box door 2 and are configured to drive the door panel 21 to move relative to the width direction of the box door 2 during the opening or closing process of the box door 2. And the second sliders 709 of all the active sliding door mechanisms are connected to the connecting rod 9, so that all the second sliders 709 can slide synchronously.

[0107] By arranging the door panel 21 on the box door 2, when the refrigeration device is an embedded type and is arranged in a groove-shaped space, or is arranged between two cabinets, the door panel 21 can be set flush with the side wall of the groove or the cabinets on both sides, so as to reduce the gap between the refrigeration device and the adjacent wall or cabinet, making it more beautiful.

[0108] At the same time, when the box door 2 rotates, the active sliding door mechanism can drive the door panel 21 to move relative to the box door 2 during the rotation process of the box door 2 to move as far as possible away from obstacles such as the wall or cabinet on the side of the box body 1 side door, so as to prevent these obstacles from blocking the door panel 21 and affecting the rotation of the box door 2, resulting in the box door 2 being unable to be opened or closed normally.

[0109] The combination of the box door 2 and the door panel 21 enables the refrigeration device to avoid interference between the door panel 21 and surrounding objects when opening and closing, greatly improving the convenience of use. Especially in a narrow kitchen environment, this design advantage is more obvious. In addition, the setting of the inner slider and guide rail in the active sliding door mechanism, and the connection of the second sliders 709 of all the active sliding door mechanisms through the connecting rod 9 enable the door panel 21 to move smoothly during the opening and closing processes, improving the service life and stability of the refrigerator.

[0110] It can be understood that if the door body assembly has the beneficial effects of the above embodiment, the refrigeration device correspondingly has the beneficial effects of the above embodiment, and its specific implementation manner can refer to the above embodiment, and will not be elaborated in this application.

[0111] It can be understood that there can be multiple storage spaces.

[0112] It can be understood that the multiple storage spaces can be arranged arbitrarily, such as arranged vertically, horizontally, etc. The multiple storage spaces can set storage conditions according to storage needs. For example, some storage spaces are set as refrigerating chambers, and another part of the storage spaces are set as freezing chambers.

[0113] Such as Figure 4As shown in the figure, an application scenario based on the above embodiments is as follows: The refrigeration device can be installed in a trough-shaped structure in the middle of a cabinet. A door panel 21 is provided on the outer side of the door 2 of the cabinet body 1 of the refrigeration device. The material and color of the door panel 21 can be designed to be similar to or the same as the material color of the outer wall of the cabinet. When the door 2 is closed, the door panel 21 is flush with the outer wall of the cabinet at the opening edge of the trough-shaped structure and fits as closely as possible to the opening of the trough-shaped structure, so that the door panel 21 and the outer wall of the cabinet can maintain visual consistency and have a small gap, making it more beautiful.

[0114] When the door 2 rotates outward to open, the active sliding door mechanism drives the door panel 21 to slide away from the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall near the first hinge 4, which may prevent the door 2 from opening to a larger angle. When the door 2 rotates to close, the active sliding door mechanism drives the door panel 21 to slide towards the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall away from the first hinge 4, which may prevent the door 2 from closing completely and affect the refrigeration preservation effect in the storage space. And when the door 2 is completely closed, the door panel 21 can return to the state flush with the cabinet body again.

[0115] In an embodiment of the present application, the cabinet body 1 has a first storage space and a second storage space. There are two door body assemblies, namely the first door body assembly and the second door body assembly. The door 2 of the first door body assembly is rotatably connected to the cabinet body 1 to open or close the first storage space, and the door 2 of the second door body assembly is rotatably connected to the cabinet body 1 to open or close the second storage space.

[0116] In this embodiment, by providing a first storage space and a second storage space on the cabinet body 1, the items to be stored are stored separately according to requirements. The first storage space and the second storage space are respectively provided with a first door body assembly and a second door body assembly, so that when the doors 2 of the first door body assembly and the second door body assembly are rotated to open and close, the corresponding door panels 21 can slide relative to the doors 2 to avoid obstacles.

[0117] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered within the scope of the claims of the present invention.
