[0052] The following is combined with Figures 1 to 7 Describe the door body assembly and refrigeration equipment of the present utility model. The active sliding door mechanism 1 and the door body assembly in the present utility model can be applied to the cabinet door 2 or the cabinet door of household appliances, such as the cabinet door 2 of a refrigerator. However, it should be understood that the door body assembly of the present utility model can also be applied to any other suitable equipment. The refrigeration equipment in the present utility model is, for example, applied as a refrigerator. However, it should be understood that the refrigeration equipment of the present utility model can also be applied as a freezer or any other suitable equipment.

[0053] In an embodiment of the present utility model, as Figures 1 to 4As shown, the door body assembly is applied to a refrigeration device, which includes a box body 4. 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 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 inside the first base 13, and a second guide rail 132 is formed outside. The first slider 11 is slidably connected inside 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. 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.

[0054] 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 inside and outside. 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 connected inside 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 outside 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, enabling the first slider 11 to 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.

[0055] During the process of the box door 2 rotating outward and opening relative to the box body 4, the box body 4 drives the first slider 11 to slide towards the hinge 5 through the traction component 17. At the same time, the first slider 11 drives the second slider 12 to slide in the opposite direction through the connecting component 14, thereby preventing the door panel 3 from interfering with external obstacles. During the process of the box door 2 rotating and closing towards one side of the box body 4, the box body 4 drives the first slider 11 to slide away from the hinge 5 through the traction component 17. At the same time, the first slider 11 drives the second slider 12 to slide in the opposite direction through the connecting component 14, thereby preventing the door panel 3 from interfering with obstacles after closing.

[0056] It can be understood that in this embodiment, the first slide rail and the second slide rail are formed on the inner and outer sides of the first base 13 respectively. Through the layered structure setting, the thickness of the entire active slide rail mechanism can be reduced to a certain extent. When installed on the box door 2, the thickness of the box door 2 can be correspondingly reduced.

[0057] According to the door body assembly of the present utility model, an active sliding door mechanism 1 including a first base 13, a first slider 11, a second slider 12, a connecting component 14 and a traction component 17 is arranged on the box door 2. The active sliding door mechanism 1 adopts a layered structure setting. A first guide rail 131 is formed on the inner side of the first base 13, and a second guide rail 132 is formed on the outer side of the first base 13. The first slider 11 is slidably connected inside 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 component 14, and the box body 4 and the first slider 11 are connected by the traction component 17. 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 component 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 box body 4, enabling the door panel 3 to avoid obstacles on both sides during the opening and closing process of the box door 2, so as to solve the interference problem during the opening process.

[0058] 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.

[0059] 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.

[0060] 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 plane contact, ball contact or sliding bearing contact. These different contact methods have their own advantages and disadvantages. For example, ball contact can reduce friction and wear, but the cost is high; while plane contact has a simple structure, but may require more frequent lubrication and maintenance. Therefore, factors such as usage conditions, cost-effectiveness and maintenance convenience should be comprehensively considered when selecting.

[0061] In addition, in order to enhance the bearing capacity and stability of the slider, reinforcing ribs, support plates or other auxiliary structures may be added to the first slider 11 and the second slider 12. These structures can increase the rigidity and anti-deformation ability of the slider, ensuring stable sliding performance when bearing the weight of the door panel 3 and external forces.

[0062] In some embodiments, Figure 3 and Figure 7 As shown, the door assembly further includes a driven sliding door mechanism 9. The driven sliding door mechanism 9 is disposed on the door 2 and connected to the door panel 3 to guide the door panel 3 to move relative to the width direction of the door 2 during the process of opening or closing the door 2.

[0063] In this embodiment, the driven sliding door mechanism 9 and the active sliding door mechanism 1 are arranged side by side on the box door 2. The active 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 process of opening or closing the box door 2. In this process, the driven sliding door mechanism 9 cooperates with the active sliding door mechanism 1 to guide the door panel 3 to move in the width direction relative to the box door 2, so as to reduce the shaking of the door panel 3 during the sliding process and make the sliding of the door panel 3 more stable.

[0064] It should be noted that the driven sliding door mechanism 9 and the active sliding door mechanism 1 can also be arranged in parallel or in other directions. In a strict geometric sense, at least the manufacturing and installation errors should be considered, and the errors of plus or minus 10° should be understood as the scope of protection of the patent.

[0065] In some embodiments, Figure 3 and Figure 7 As shown, 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 arranged 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 auxiliary role in the sliding of the door panel 3, so that the door panel 3 slides more smoothly relative to the box door 2. At the same time, the driven sliding door mechanism 9 can cooperate with the active sliding door mechanism 1 to limit the movement direction of the door panel 3, reduce the shaking of the door panel 3 during the sliding process, and make the sliding more stable.

[0066] The driven sliding door mechanism 9 provided in this embodiment can effectively limit the movement direction of the door panel 3 through its collaborative work with the active sliding door mechanism 1. This enables the door panel 3 to move along a predetermined trajectory during the sliding process, avoiding wobbling and instability caused by direction deviation. This limiting effect ensures the stability of the door panel 3.

[0067] 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 rollably disposed in the third rolling gap 912.

[0068] In this embodiment, by forming the 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 by disposing the rollable third ball in the third rolling gap 912, the third slider 92 can slide along the third guide rail 911 through the rolling of the third ball. 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.

[0069] In some embodiments, the driven sliding door mechanism 9 further includes: a third support frame. The third support frame is disposed between the third slider 92 and the third guide rail 911. The third support frame is provided with a third limiting notch, and the third ball is disposed in the third limiting notch, and the third ball abuts against the third slider 92 and the third guide rail 911.

[0070] In this embodiment, by disposing the third support frame between the third slider 92 and the third guide rail 911, and forming the third limiting notch on the third support frame to dispose the third ball, the third ball can be limited to prevent the third ball from rolling and deviating in the third rolling gap 912, making the sliding of the third slider 92 more stable and reliable.

[0071] Generally, there are multiple groups of third balls. The third guide rail 911 is provided with a third concave surface, and the third slider 92 is formed with a third groove. 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 balls is respectively disposed in each row of the third rolling gaps 912. By providing multiple rows of third rolling gaps 912 and disposing a group of third balls in each row of the third rolling gaps 912, multiple groups of third 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.

[0072] In some embodiments, such as Figures 1 to 7As shown, for facilitating the hanging connection of the door panel 3, slots for hanging the door panel 3 are provided on the second slider 12 and / or the third slider 92. The slots can be directly provided on the second slider 12 and / or the third slider 92, or the slots can be provided in the way of connecting blocks.

[0073] Under normal circumstances, the slots can be directly machined on the second slider 12 and / or the third slider 92. The shape and size of the slots need to match the hanging components on the door panel 3 to ensure that the door panel 3 can be stably hung on the slider. The advantage of this method is that the structure is simple, direct and effective, without the need for 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.

[0074] In order to simplify the mechanism of the slider, connecting blocks can also be provided on the second slider 12 and / or the third slider 92, and then the slots are machined on the connecting blocks. The connecting blocks can be components made of the same or different materials as the slider, and are fixed on the slider by welding, screwing, etc. 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.

[0075] 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 hung on the active sliding door mechanism 1 and the driven sliding door mechanism 9 through the hook and the first slot 122 and the second slot 921.

[0076] In some embodiments, 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.

[0077] In this embodiment, by bypassing one end of the first base 13 with the first connecting member 14 and connecting it 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 bypassing the other end of the first base 13 with the second connecting member 14 and connecting it to the first slider 11 and the second slider 12 respectively, when the first slider 11 slides away from this 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 this other end of the first base 13 through the second connecting member 14, so 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 as the box door 2 rotates 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.

[0078] In some embodiments, as Figures 3 to 5 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 butted against one end 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 butted against the other end 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.

[0079] Specifically, the first fixing seat 15 is connected to one end of the first base 13 and serves as an extension and support for the first guide rail 131 and the second guide rail 132 at this end. A first limiting groove is formed on the first fixing 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. Both ends of the first limiting groove are butted against one end of the first guide rail 131 and the second guide rail 132. The existence of the first limiting groove restricts the offset and sway of the first connecting member 14 during the sliding process, improving the operating precision and reliability of the entire active sliding door mechanism 1. The second fixing seat 16 corresponds to the first fixing seat 15. The second fixing seat 16 is connected to the other end of the first base 13 to provide 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 fixing 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. Both ends of the second limiting groove are butted against the other end of the first guide rail 131 and the second guide rail 132 to provide 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 restricting the offset and sway of the connecting member 14.

[0080] In order to achieve the installation of the active slider mechanism, in some embodiments, such as Figures 3 to 6 shown, fixing holes are provided on the first fixing seat 15 and / or the second fixing seat 16. The active sliding door mechanism 1 further includes fixing members, and 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.

[0081] In this embodiment, by fixing the first fixing seat 15 and / or the second fixing seat 16 connected to the first base 13 on the box door 2 through the fixing members, it can be ensured that the mechanism will not loosen or shift due to external forces or vibrations 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 members with the fixing holes and tighten them 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 members without complex disassembly work. This greatly improves the maintainability and flexibility of the equipment.

[0082] 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.

[0083] In some embodiments, such as Figure 6As 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.

[0084] In this embodiment, by 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 respectively, 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, enabling the first slider 11 to slide along the first guide rail 131 through the rolling of the first ball 18, and the second slider 12 to slide along the second guide rail 132 through the rolling of the second ball 19. In the rolling mode, the friction is small, and the sliding of the first slider 11 and the second slider 12 is smoother.

[0085] In an embodiment of the present utility model, as Figures 3 to 6 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 arranged between the first slider 11 and the first guide rail 131. The first support frame 181 is provided with a first limiting notch at a position corresponding to the first rolling gap 111, and the first ball 18 is arranged 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 arranged between the second slider 12 and the second guide rail 132. The second support frame 191 is provided with a second limiting notch at a position corresponding to the second rolling gap 121, and the second ball 19 is arranged in the second limiting notch, and the second ball 19 abuts against the second slider 12 and the second guide rail 132.

[0086] In this embodiment, by arranging the first support frame 181 between the first slider 11 and the first guide rail 131, and forming a first limiting notch on the first support frame 181 to arrange the first ball 18, the first ball 18 can be limited to prevent it from rolling and shifting in the first rolling gap 111, making the sliding of the first slider 11 more stable and reliable; similarly, by arranging 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.

[0087] In an embodiment of the present utility model, as Figures 3 to 6As shown, there are multiple sets of the first ball bearings 18 and the second ball bearings 19. At both ends inside the first guide rail 131, there are first concave surfaces. On the first slider 11, there is a first groove. Two rows of first rolling clearances 111 are formed between the side walls of the first groove and the first concave surfaces. Each set of the first ball bearings 18 is respectively arranged in each row of the first rolling clearances 111. At both ends outside the second guide rail 132, there are second concave surfaces. On the second slider 12, there is a second groove. Two rows of second rolling clearances 121 are formed between the side walls of the second groove and the second concave surfaces. Each group of the second ball bearings 19 is respectively arranged in each row of the second rolling clearances 121.

[0088] Specifically, by providing two rows of the first rolling clearances 111 and arranging one set of the first ball bearings 18 in each row of the first rolling clearances 111, multiple sets of the first ball bearings 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 providing two rows of the second rolling clearances 121 and arranging one set of the second ball bearings 19 in each row of the second rolling clearances 121, multiple sets of the second ball bearings 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 providing the first groove on the first slider 11 and the first concave surface on the first guide rail 131, the first concave surface and the first groove form the first rolling clearance 111 relatively. The first concave surface and the first groove respectively abut against both sides of the first ball bearing 18. The first ball bearing 18 can roll within the first rolling clearance 111 to achieve the relative sliding between the first slider 11 and the first guide rail 131. At the same time, the first concave surface can limit the position of the first ball bearing 18 on the first guide rail 131 to prevent the first ball bearing 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 clearance 121 relatively. The second concave surface and the second groove respectively abut against both sides of the second ball bearing 19, so that the second ball bearing 19 can roll without shifting when achieving the relative sliding between the second slider 12 and the second guide rail 132, making the sliding of the second slider 12 more stable and smooth.

[0089] Optionally, multiple first rolling clearances 111 in each row can be arranged at intervals along the extending direction of the first guide rail 131, and multiple second rolling clearances 121 in each row can be arranged at intervals along the extending direction of the second guide rail 132.

[0090] 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 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 better fit the second ball 19, with a larger force-bearing area and more stable and reliable rolling.

[0091] In an embodiment of another aspect of the present invention, 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.

[0092] In this embodiment, 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, 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 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 inside the first base 13, and a second guide rail 132 is formed outside. The first slider 11 is slidably connected inside the first guide rail 131. The second slider 12 is slidably sleeved outside the second guide rail 132 and is used to connect to the door panel 3. Both 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 to 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.

[0093] By providing the door panel 3 on the box door 2, when the refrigeration device is an inlaid type and is disposed in a groove-shaped space or between two cabinets, the door panel 3 can be set flush with the side walls 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.

[0094] At the same time, when the box door 2 rotates, the driving sliding door mechanism 1 can drive the door panel 3 to move relative to the box door 2 during the rotation of the box door 2 to move as far as possible away from obstacles such as the wall or cabinet on the side door of the box body 4, so as to avoid these obstacles blocking the door panel 3 and affecting the rotation of the box door 2, resulting in the box door 2 being unable to be normally opened or closed.

[0095] The combination of the door 2 and the door panel 3 enables the refrigeration device 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.

[0096] It can be understood that if the door body assembly has the beneficial effects of the above embodiments, the refrigeration device correspondingly has the beneficial effects of the above embodiments. The specific implementation manners can refer to the above embodiments, and the present utility model will not be elaborated herein.

[0097] In some embodiments, as Figure 1 and Figure 2 shown, the door body assembly and the cabinet 4 are configured to be disposed in the installation space 8 formed between the first cabinet 6 and the second cabinet 7. An opening is provided on the outer side of the installation space 8. This design enables the door body assembly and the cabinet 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 towards the hinge 5, so that the door panel 3 can avoid the side walls of the first cabinet 6 and the second cabinet 7.

[0098] 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 towards the hinge 5. In order to avoid interference between the door panel 3 and the side walls of the first cabinet 6 and the second cabinet 7, and in order to enable the door panel 3 to be smoothly opened or closed without colliding with or jamming against the side walls of the cabinet through the movement of the preset distance.

[0099] 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 7, enabling the door 2 to be fully opened, facilitating users to access items.

[0100] Similarly, during the closing 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 towards the hinge 5. In this way, the door panel 3 can smoothly avoid the side wall of the first cabinet 6, enabling the door 2 to be fully closed, maintaining the overall aesthetics and sealing performance.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model, rather than to limit it.
