[0054] Next, in combination with Figures 1 to 7 Describe the door body assembly and refrigeration equipment of this application. The active sliding door mechanism 1 and the door body assembly in this application can be applied to the cabinet doors 2 of household appliances or cabinet doors, etc., such as the cabinet door 2 of a refrigerator. However, it should be understood that the door body assembly of this application can also be applied to any other suitable equipment. The refrigeration equipment in this application is, for example, applied as a refrigerator. However, it should be understood that the refrigeration equipment of this application can also be applied as a freezer or any other suitable equipment.

[0055] In one embodiment of this application, as Figures 1 to 4As shown in the figure, the door body assembly is applied to a refrigeration device. The refrigeration device includes a box body 4, and the door body assembly includes: a driving sliding door mechanism 1, a box door 2, and a door panel 3. The box door 2 is rotatably connected to the box body 4, and the box door 2 is adapted to open or close the storage space of the box body 4. The door panel 3 is slidably disposed outside the box door 2. Among them, the driving sliding door mechanism 1 is disposed on the box door 2 and includes: a first base 13, a first slider 11, a second slider 12, a connecting member 14, and a traction member 17. A first guide rail 131 is formed on the upper side of the first base 13, and a second guide rail 132 is formed on the lower side. The first slider 11 is slidably sleeved outside the first guide rail 131. The second slider 12 is slidably sleeved outside the second guide rail 132 and is used to connect with the door panel 3. Two ends of the connecting member 14 are respectively connected to the first slider 11 and the second slider 12. One end of the traction member 17 is used to connect with the box body 4, and the other end is connected to the first slider 11. During the opening or closing process of the box door 2, the box body 4 drives the first slider 11 to move on the first guide rail 131 through the traction member 17, and the first slider 11 drives the second slider 12 to move in the opposite direction on the second guide rail 132 through the connecting member 14, so that the second slider 12 drives the door panel 3 to move relative to the width direction of the box body 4.

[0056] In this embodiment, the box body 4 is the main part of the refrigeration device. A storage space is provided inside the box body 4 for storing food or other items that need to be refrigerated or frozen. The box door 2 is installed on the box body 4 through a certain rotational connection method (such as a hinge 5) and can rotate around one or more pivot points to open and close the storage space. The door panel 3 is an additional, slidable component disposed outside the box door 2. The first base 13 is fixed on the box door 2, and a first guide rail 131 and a second guide rail 132 are respectively formed on its upper side and lower side. The first guide rail 131 and the second guide rail 132 respectively provide tracks for the sliding of the first slider 11 and the second slider 12. The first slider 11 is slidably sleeved on the first guide rail 131, is connected to the box body 4 through the traction member 17, and is driven by the box body 4 to move on the first guide rail 131. The second slider 12 is also slidably sleeved on the second guide rail 132 but is connected to the door panel 3 and is used to drive the sliding of the door panel 3. The connecting member 14 can be a connecting component such as a traction rope or a transmission belt. Two ends of the connecting member 14 are respectively connected to the first slider 11 and the second slider 12, so that the first slider 11 can drive the second slider 12 to move synchronously and move in opposite directions. This design ensures that the door panel 3 can slide smoothly along the width direction of the box body 4. One end of the traction member 17 is connected to the box body 4, and the other end is connected to the first slider 11. It is a component for transmitting power between the box body 4 and the first slider 11. When the box door 2 is opened or closed, the box body 4 drives the first slider 11 to move through the traction member 17, and then drives the door panel 3 to slide.

[0057] During the process of the cabinet door 2 rotating outward and opening relative to the cabinet body 4, the cabinet body 4 drives the first slider 11 to slide towards the hinge 5 through the traction member 17. At the same time, the first slider 11 drives the second slider 12 to slide in the opposite direction through the connecting member 14, thereby preventing the door panel 3 from interfering with obstacles on the outside. During the process of the cabinet door 2 rotating towards the cabinet body 4 and closing, the cabinet body 4 drives the first slider 11 to slide away from the hinge 5 through the traction member 17. At the same time, the first slider 11 drives the second slider 12 to slide in the opposite direction through the connecting member 14, thereby preventing the door panel 3 from interfering with obstacles after closing.

[0058] It can be understood that in this embodiment, the first slide rail and the second slide rail are formed on the upper and lower sides of the first base 13, which can reduce the thickness of the entire active slide rail mechanism to a certain extent. When installed on the cabinet door 2, the thickness of the cabinet door 2 can be correspondingly reduced.

[0059] According to the door body assembly of the present application, the active sliding door mechanism 1 including the first base 13, the first slider 11, the second slider 12, the connecting member 14 and the traction member 17 is arranged on the cabinet door 2. The first guide rail 131 is formed on the upper side of the first base 13, and the second guide rail 132 is formed on the lower side of the first base 13. The first slider 11 is slidably sleeved outside the first guide rail 131, and the second slider 12 is slidably sleeved outside the second guide rail 132. The first slider 11 and the second slider 12 are connected by the connecting member 14, and the cabinet body 4 and the first slider 11 are connected by the traction member 17. During the opening or closing process of the cabinet door 2, the cabinet body 4 drives the first slider 11 to move on the first guide rail 131 through the traction member 17, while the second slider 12 moves in the opposite direction on the second guide rail 132, so that the second slider 12 can drive the door panel 3 to move relative to the width direction of the cabinet body 4, so that the door panel 3 can avoid obstacles on both sides during the opening and closing process of the cabinet door 2, so as to solve the interference problem during the opening process.

[0060] It should be noted that in practical applications, the designs of the first slider 11 and the second slider 12 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.

[0061] From the perspective of materials, the first slider 11 and the second slider 12 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 the sliding process, and ensure the smoothness of sliding.

[0062] In terms of structural design, the first slider 11 and the second slider 12 can adopt various forms of guide rail contact surfaces, such as planar 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 planar 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.

[0063] In addition, in order to enhance the load-bearing capacity and stability of the sliders, stiffeners, support plates or other auxiliary structures can also be added to the first slider 11 and the second slider 12. These structures can increase the rigidity and anti-deformation ability of the sliders, ensuring stable sliding performance when bearing the weight of the door panel 3 and external forces.

[0064] In some embodiments, such as Figure 3 and Figure 4 shown, the connecting member 14 includes: a first connecting member 14 and a second connecting member 14. The first connecting member 14 bypasses one end of the first base 13, and its two ends are respectively connected to one end of the first slider 11 and the second slider 12. The second connecting member 14 bypasses the other end of the first base 13, and its two ends are respectively connected to the other end of the first slider 11 and the second slider 12.

[0065] In this embodiment, by connecting the first connecting member 14 around one end of the first base 13 to the first slider 11 and the second slider 12 respectively, when the first slider 11 slides away from this end of the first base 13 under the drive of the box body 4, the first slider 11 drives the second slider 12 to slide towards this end of the first base 13 through the first connecting member 14; at the same time, by connecting the second connecting member 14 around the other end of the first base 13 to the first slider 11 and the second slider 12 respectively, when the first slider 11 slides away from the other end of the first base 13 under the drive of the box door 2, the first slider 11 drives the second slider 12 to slide towards the other end of the first base 13 through the second connecting member 14, so as to achieve that when the first slider 11 slides towards both ends of the first base 13 respectively, it can drive the second slider 12 to slide in the opposite direction to the first slider 11, and further enable the door panel 3 to slide relative to the box door 2 when the box door 2 opens and closes, so as to avoid interference with obstacles and affect the opening and closing of the box door 2.

[0066] In some embodiments, such as Figures 3 to 5As shown, the active sliding door mechanism 1 further includes a first fixed seat 15 and a second fixed seat 16. The first fixed seat 15 is connected to one end of the first base 13 and is formed with a first limiting groove. The two ends of the first limiting groove are docked with one ends of the first guide rail 131 and the second guide rail 132, and a part of the first connecting member 14 is slidably disposed in the first limiting groove; the second fixed seat 16 is connected to the other end of the first base 13 and is formed with a second limiting groove. The two ends of the second limiting groove are docked with the other ends of the first guide rail 131 and the second guide rail 132, and a part of the second connecting member 14 is slidably disposed in the second limiting groove.

[0067] Specifically, the first fixed seat 15 is connected to one end of the first base 13 and serves as an extension and support of the first guide rail 131 and the second guide rail 132 at this end. A first limiting groove is formed on the first fixed seat 15. The first limiting groove not only provides an additional sliding track for the first connecting member 14, but also ensures the stability and accuracy of the first connecting member 14 during the sliding process. The two ends of the first limiting groove are docked with one ends of the first guide rail 131 and the second guide rail 132. The existence of the first limiting groove limits the offset and sway of the first connecting member 14 during the sliding process, improving the operation precision and reliability of the entire active sliding door mechanism 1. The second fixed seat 16 corresponds to the first fixed seat 15. The second fixed seat 16 is connected to the other end of the first base 13 and provides support and extension for the first guide rail 131 and the second guide rail 132 at this end. A second limiting groove is formed on the second fixed seat 16, and its design is similar to that of the first limiting groove, but is located at the other end of the active sliding door mechanism 1. The two ends of the second limiting groove are docked with the other ends of the first guide rail 131 and the second guide rail 132, providing guidance and limitation for the sliding of the second connecting member 14. Similar to the first limiting groove, the second limiting groove also plays a role in limiting the offset and sway of the connecting member 14.

[0068] In order to achieve the installation of the active slider mechanism, in some embodiments, as Figures 3 to 6 shown, the first fixed seat 15 and / or the second fixed seat 16 are provided with fixing holes, and the active sliding door mechanism 1 further includes fixing members. The fixing members pass through the fixing holes to be connected to the box door 2, so that the entire active sliding door mechanism 1 can be fixed on the box door 2.

[0069] In this embodiment, the first fixing seat 15 and / or the second fixing seat 16 connected to the first base 13 are fixed on the box door 2 through fixing members, which can ensure that the mechanism will not loosen or shift due to external force or vibration during operation. The design of the fixing holes and the fixing members makes the installation process simple and fast. The operator only needs to align the fixing member with the fixing hole and tighten it to complete the connection between the active sliding door mechanism 1 and the box door 2. When it is necessary to repair or replace the active sliding door mechanism 1, the active sliding door mechanism 1 can be removed from the box door 2 by simply removing the fixing member, without complex disassembly work. This greatly improves the maintainability and flexibility of the equipment.

[0070] During specific implementation, appropriate fixing members such as screws, bolts, rivets, etc. can be selected according to the structure and material of the box door 2. At the same time, it is also necessary to ensure that the position and size of the fixing holes match the fixing members to ensure the firmness and stability of the connection.

[0071] In some embodiments, such as Figure 6 shown, the active sliding door mechanism 1 further includes: a first ball 18 and a second ball 19. A first rolling gap 111 is formed between the first slider 11 and the first guide rail 131, and the first ball 18 is rotatably arranged in the first rolling gap 111; a second rolling gap 121 is formed between the second slider 12 and the second guide rail 132, and the second ball 19 is rotatably arranged in the second rolling gap 121.

[0072] In this embodiment, by respectively forming the first rolling gap 111 between the first slider 11 and the first guide rail 131 and the second rolling gap 121 between the second slider 12 and the second guide rail 132, direct contact between the first slider 11 and the first guide rail 131 and between the second slider 12 and the second guide rail 132 can be avoided. The rotatable first ball 18 and second ball 19 are respectively arranged in the first rolling gap 111 and the second rolling gap 121, so that the first slider 11 can slide along the first guide rail 131 through the rolling of the first ball 18, and the second slider 12 can slide along the second guide rail 132 through the rolling of the second ball 19. The friction is small in the rolling mode, and the sliding of the first slider 11 and the second slider 12 is smoother.

[0073] In an embodiment of the present application, such as Figures 3 to 6As shown, the active sliding door mechanism 1 further includes: a first support frame 181 and a second support frame 191. The first support frame 181 is disposed between the first slider 11 and the first guide rail 131. The first support frame 181 is provided with a first limiting notch corresponding to the position of the first rolling gap 111. The first ball 18 is disposed in the first limiting notch, and the first ball 18 abuts against the first slider 11 and the first guide rail 131. The second support frame 191 is disposed between the second slider 12 and the second guide rail 132. The second support frame 191 is provided with a second limiting notch corresponding to the position of the second rolling gap 121. The second ball 19 is disposed in the second limiting notch, and the second ball 19 abuts against the second slider 12 and the second guide rail 132.

[0074] In this embodiment, by disposing the first support frame 181 between the first slider 11 and the first guide rail 131, a first limiting notch is formed on the first support frame 181 to dispose the first ball 18, so as to limit the first ball 18 and prevent the first ball 18 from rolling and shifting in the first rolling gap 111, making the sliding of the first slider 11 more stable and reliable; similarly, by disposing the second support frame 191 between the second slider 12 and the second guide rail 132 to limit the second ball 19, the sliding of the second slider 12 is made more stable and reliable.

[0075] In an embodiment of the present application, as Figures 3 to 6 shown, there are multiple groups of the first balls 18 and the second balls 19. The first guide rail 131 is provided with a plurality of first concave surfaces sequentially arranged along its circumferential direction. A first groove is formed on the first slider 11. The side wall of the first groove and the plurality of first concave surfaces form multiple rows of first rolling gaps 111. Each group of the first balls 18 is respectively disposed in each row of the first rolling gaps 111. The second guide rail 132 is provided with a plurality of second concave surfaces sequentially arranged along its circumferential direction. A second groove is formed on the second slider 12. The side wall of the second groove and the plurality of second concave surfaces form multiple rows of second rolling gaps 121. Each group of the second balls 19 is respectively disposed in each row of the second rolling gaps 121.

[0076] Specifically, by setting multiple rows of first rolling gaps 111 and arranging a set of first balls 18 in each row of the first rolling gaps 111, multiple sets of first balls 18 can form multiple rolling support points between the first slider 11 and the first guide rail 131, making the sliding of the first slider 11 relative to the first guide rail 131 more stable and smooth. Similarly, by setting multiple rows of second rolling gaps 121 and arranging a set of second balls 19 in each row of the second rolling gaps 121, multiple sets of second balls 19 can also form multiple rolling support points between the second slider 12 and the second guide rail 132, making the sliding of the second slider 12 relative to the first guide rail 131 more stable and smooth. At the same time, by setting a first groove on the first slider 11 and a first concave surface on the first guide rail 131, the first concave surface and the first groove form the first rolling gap 111 relatively. The first concave surface and the first groove respectively abut against both sides of the first ball 18, and the first ball 18 can roll within the first rolling gap 111 to achieve the relative sliding of the first slider 11 and the first guide rail 131. Meanwhile, the first concave surface can limit the position of the first ball 18 on the first guide rail 131 to prevent the first ball 18 from shifting on the first guide rail 131, making the sliding of the first slider 11 more stable and smooth. Similarly, the second groove on the second slider 12 and the second concave surface on the second guide rail 132 form the second rolling gap 121 relatively. The second concave surface and the second groove respectively abut against both sides of the second ball 19, so that the second ball 19 rolls without shifting when achieving the relative sliding of the second slider 12 and the second guide rail 132, making the sliding of the second slider 12 more stable and smooth.

[0077] Optionally, multiple first rolling gaps 111 in each row can be arranged at intervals along the extending direction of the first guide rail 131, and multiple second rolling gaps 121 in each row can be arranged at intervals along the extending direction of the second guide rail 132.

[0078] Optionally, the first concave surface is an arc surface that fits the first ball 18, and an arc surface that fits the first ball 18 is also formed at the position corresponding to the first concave surface on the side wall of the first groove, so that the first concave surface and the first groove can better fit the first ball 18, with a larger force-bearing area and more stable and reliable rolling. Similarly, the second concave surface is an arc surface that fits the second ball 19, and an arc surface that fits the second ball 19 is also formed at the position corresponding to the second concave surface on the side wall of the second groove, so that the second concave surface and the second groove can better fit the second ball 19, with a larger force-bearing area and more stable and reliable rolling.

[0079] In some embodiments, such as Figure 3 and Figure 7As shown in the figure, the door body assembly further includes: a driven sliding door mechanism 9. The driven sliding door mechanism 9 is disposed on the box door 2 and is connected to the door panel 3, and is used to guide the door panel 3 to move in the width direction of the box door 2 during the opening or closing of the box door 2.

[0080] In this embodiment, the driven sliding door mechanism 9 and the driving sliding door mechanism 1 are arranged side by side on the box door 2. The driving sliding door mechanism 1 is used to drive the door panel 3 to move in the width direction of the box body 4 during the opening or closing of the box door 2. During this process, the driven sliding door mechanism 9 cooperates with the driving sliding door mechanism 1 to guide the door panel 3 to move in the width direction of the box door 2, so as to reduce the shaking generated during the sliding of the door panel 3 and make the sliding of the door panel 3 more stable.

[0081] It should be noted that the driven sliding door mechanism 9 and the driving sliding door mechanism 1 can also be arranged in parallel or in other directions. When strictly in the geometric sense, at least the manufacturing and installation errors should be considered, and errors of plus or minus 10° should be understood as the scope protected by the patent.

[0082] In some embodiments, such as Figure 3 and Figure 7 As shown in the figure, the driven sliding door mechanism 9 includes: a second base 91 and a third slider 92. The second base 91 is connected to the box door 2 and is formed with a third guide rail 911; the third slider 92 is slidably disposed on the third guide rail 911 and is connected to the door panel 3. The third slider 92 can slide with the door panel 3 when the door panel 3 slides relative to the box door 2, and plays a supporting and assisting role in the sliding of the door panel 3, making the sliding of the door panel 3 relative to the box door 2 smoother. At the same time, the driven sliding door mechanism 9 can cooperate with the driving sliding door mechanism 1 to limit the movement direction of the door panel 3, reduce the shaking generated during the sliding of the door panel 3, and make the sliding more stable.

[0083] The driven sliding door mechanism 9 provided in this embodiment can effectively limit the movement direction of the door panel 3 through the coordinated work with the driving sliding door mechanism 1. So that the door panel 3 will move along a predetermined trajectory during the sliding process, avoiding the shaking and instability caused by the direction deviation. This limiting effect ensures the stability of the door panel 3.

[0084] In some embodiments, the driven sliding door mechanism 9 further includes: a third ball. A third rolling gap 912 is formed between the third slider 92 and the third guide rail 911, and the third ball is rotatably disposed in the third rolling gap 912.

[0085] In this embodiment, by forming a third rolling gap 912 between the third slider 92 and the third guide rail 911, direct contact between the third slider 92 and the third guide rail 911 can be avoided, and third rolling balls are arranged in the third rolling gap 912 so that the third slider 92 can slide along the third guide rail 911 by rolling of the third rolling balls. With the rolling method, the frictional force is small, the third slider 92 slides more smoothly, and the resistance during the sliding process can be effectively reduced.

[0086] In some embodiments, the driven sliding door mechanism 9 further includes: a third support frame. The third support frame is arranged between the third slider 92 and the third guide rail 911. A third limiting notch is provided on the third support frame, and the third rolling balls are arranged in the third limiting notch and are in contact with the third slider 92 and the third guide rail 911.

[0087] In this embodiment, by arranging a third support frame between the third slider 92 and the third guide rail 911, a third limiting notch is formed on the third support frame to arrange the third rolling balls, so as to limit the third rolling balls and prevent the third rolling balls from rolling and shifting in the third rolling gap 912, making the sliding of the third slider 92 more stable and reliable.

[0088] Generally, there are multiple groups of third rolling balls. A third concave surface is provided on the third guide rail 911, and a third groove is formed on the third slider 92. The side walls of the third groove and the multiple third concave surfaces form multiple rows of third moving gaps, and each group of third rolling balls is respectively arranged in each row of the third rolling gaps 912. By arranging multiple rows of third rolling gaps 912 and arranging a group of third rolling balls in each row of the third rolling gaps 912, multiple groups of third rolling balls can form multiple rolling support points between the third slider 92 and the third guide rail 911, making the third slider 92 slide more stably and smoothly relative to the third guide rail 911.

[0089] In some embodiments, as Figures 1 to 7 shown, for facilitating the hanging of the door panel 3, a slot for hanging the door panel 3 is provided on the second slider 12 and / or the third slider 92. The slot can be directly provided on the second slider 12 and / or the third slider 92, or the slot can be provided in the way of a connecting block.

[0090] Generally, the slot can be directly machined on the second slider 12 and / or the third slider 92. The shape and size of the slot need to match the hanging components on the door panel 3 to ensure that the door panel 3 can be firmly hung on the slider. The advantage of this method is that the structure is simple, direct and effective, without additional connecting components. However, it may be necessary to customize the machining of the slider to meet the design requirements of different door panels 3.

[0091] To simplify the mechanism of the slider, a connecting block can also be provided on the second slider 12 and / or the third slider 92, and then a slot is machined on the connecting block. The connecting block can be a component made of the same or different material as the slider and is fixed to the slider by welding, screwing or other means. The advantage of this method is higher flexibility, and different connecting blocks and slot designs can be selected according to needs to adapt to door panels 3 of different shapes, sizes and weights.

[0092] In this embodiment, a first slot 122 is provided on the second slider 12, and a second slot 921 is provided on the third slider 92. The door panel 3 can be simultaneously hooked on the active sliding door mechanism 1 and the driven sliding door mechanism 9 through the hook, the first slot 122 and the second slot 921.

[0093] In an embodiment of another aspect of the present application, as Figures 3 to 6 shown, a refrigeration device is provided, including: a box body 4 and a door body assembly provided in any of the above embodiments. Among them, the box body 4 forms a storage space, and the box door 2 is rotatably connected to the box body 4 and is adapted to open or close the storage space.

[0094] In this embodiment, the door body assembly includes: an active sliding door mechanism 1, a box door 2 and a door panel 3; the box door 2 is rotatably connected to the box body 4, and the box door 2 is adapted to open or close the storage space of the box body 4, and the door panel 3 is slidably disposed outside the box door 2. Among them, the active sliding door mechanism 1 is disposed on the box door 2 and includes: a first base 13, a first slider 11, a second slider 12, a connecting member 14 and a traction member 17. A first guide rail 131 is formed on the upper side of the first base 13, and a second guide rail 132 is formed on the lower side. The first slider 11 is slidably sleeved outside the first guide rail 131. The second slider 12 is slidably sleeved outside the second guide rail 132 and is used for connecting with the door panel 3. Two ends of the connecting member 14 are respectively connected to the first slider 11 and the second slider 12. One end of the traction member 17 is used for connecting with the box body 4, and the other end is connected to the first slider 11. During the opening or closing process of the box door 2, the box body 4 drives the first slider 11 to move on the first guide rail 131 through the traction member 17, and the first slider 11 drives the second slider 12 to move in the opposite direction on the second guide rail 132 through the connecting member 14, so that the second slider 12 drives the door panel 3 to move relative to the width direction of the box body 4.

[0095] By providing the door panel 3 on the box door 2, when the refrigeration device is an embedded type and is disposed in a groove-shaped space, or is disposed between two cabinets, the door panel 3 can be 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.

[0096] Meanwhile, when the door 2 rotates, the active sliding door mechanism 1 can drive the door panel 3 to move relative to the door 2 during the rotation of the door 2 to move as far away as possible from obstacles such as the wall of the side door of the cabinet body 4 or the cabinet, so as to prevent these obstacles from blocking the door panel 3 and affecting the rotation of the door 2, resulting in the door 2 being unable to be opened or closed normally.

[0097] The combination of the door 2 and the door panel 3 enables the refrigeration equipment to avoid interference between the door panel 3 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 slider and guide rail in the active sliding door mechanism 1 enables the door panel 3 to move smoothly during the opening and closing processes, improving the service life and stability of the refrigerator.

[0098] It can be understood that if the door body assembly has the beneficial effects of the above embodiments, the refrigeration equipment correspondingly has the beneficial effects of the above embodiments. The specific implementation manners can refer to the above embodiments, and will not be elaborated in this application.

[0099] In some embodiments, such as Figure 1 and Figure 2 shown, the door body assembly and the cabinet body 4 are used to be arranged in the installation space 8 formed between the first cabinet body 6 and the second cabinet body 7. An opening is provided on the outer side of the installation space 8. This design enables the door body assembly and the cabinet body 4 to be integrally embedded in the cabinet. During the process of the door 2 passing through the opening to control the opening or closing of the storage space, the active sliding door mechanism 1 is configured to drive the door panel 3 to move a preset distance on the door 2 in a direction away from or close to the hinge 5, so that the door panel 3 can avoid the side walls of the first cabinet body 6 and the second cabinet body 7.

[0100] During the process of the door 2 passing through the opening to control the opening or closing of the storage space, the active sliding door mechanism 1 is configured to drive the door panel 3 to move a preset distance on the door 2 in a direction away from or close to the hinge 5. In order to avoid interference between the door panel 3 and the side walls of the first cabinet body 6 and the second cabinet body 7, and in order to enable the door panel 3 to be smoothly opened or closed without colliding with or getting stuck on the side walls of the cabinet through the movement of the preset distance.

[0101] For example, as Figure 1 and Figure 2 shown, during the opening process of the door 2, the active sliding door mechanism 1 drives the door panel 3 to move a preset distance along the door 2 in a direction away from the hinge 5. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet body 7, enabling the door 2 to be fully opened, facilitating users to access items.

[0102] Similarly, during the closing process of the cabinet door 2, the active sliding door mechanism 1 drives the door panel 3 to move a preset distance along the cabinet door 2 towards the hinge 5. In this way, the door panel 3 can smoothly avoid the side wall of the first cabinet body 6, enabling the cabinet door 2 to be fully closed, maintaining the overall aesthetics and sealing performance.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended 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.
