[0060] The active sliding door mechanism, door assembly, and refrigeration device of this application are described below with reference to Figures 1 to 5. The active sliding door mechanism and door assembly of this application can be applied to cabinet doors or other doors of household appliances, such as refrigerator doors. However, it should be understood that the door mechanism and door assembly of this application can also be applied to dishwashers, washing machines, or any other suitable equipment. The refrigeration device of this application is applied, for example, to a refrigerator. However, it should be understood that the refrigeration device of this application can also be applied to a freezer or any other suitable equipment.

[0061] In one embodiment of this application, as shown in Figures 1 to 4, the active sliding door mechanism 7 is applied to a refrigeration device. The refrigeration device includes a cabinet 1, a door 2, and a door panel 21. The door 2 is rotatably mounted on the cabinet 1, and the outer side of the door 2 is provided with a door panel 21 that can slide along it. The active sliding door mechanism 7 includes: a first base for mounting on the door 2, with a first guide rail 710 formed on one side and a second guide rail 705 formed on the other side; a first slider 715 and a traction mechanism, the first slider 715 being slidably mounted on the first guide rail 710; the first slider 715 being connected to the housing 1 via the traction mechanism; a second slider 709 being slidably mounted on the second guide rail 705, the second slider 709 being connected to the door panel 21; a connector and a rotating support 716, the two ends of the connector being connected to the first slider 715 and the second slider 709 respectively, a portion of the connector pressing against the rotating support 716; when the first slider 715 moves on the first guide rail 710, the first slider 715 drives the connector to move on the rotating support 716, thereby driving the second slider 709 to move in the opposite direction on the second guide rail 705 via the connector.

[0062] In this embodiment, the first base can be mounted on the door 2. The connecting component can be a traction rope, a transmission belt, or other connecting parts. The two ends of the connecting component 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 causing the door panel 21 to slide relative to the door 2.

[0063] By setting a rotatable rotating support 716, a portion of the connector is pressed onto the rotating support 716, so that the connector is tightened while adjusting the extension and movement direction of the connector, so that when the first slider 715 moves along the first guide rail 710, it can drive the second slider 709 to move on the second guide rail 705 through the connector, and the movement direction of the second slider 709 is opposite to the movement direction of the first slider 715, so that the door panel 21 can avoid obstacles.

[0064] Specifically, during the process of the door 2 rotating outwards to open the box body 1, the box body 1 drives the first slider 715 to slide towards the first hinge 4 via a traction mechanism. Simultaneously, the first slider 715, through a connecting member, drives the second slider 709 to slide in the opposite direction (i.e., away from the first hinge 4), thereby preventing interference between the door panel 21 and external obstacles. During the process of the door 2 rotating outwards to close to close the box body 1, the box body 1 drives the first slider 715 to slide away from the first hinge 4 via a traction mechanism. Simultaneously, the first slider 715, through a connecting member, drives the second slider 709 to slide in the opposite direction (i.e., towards the first hinge 4), thereby preventing interference between the closed door panel 21 and obstacles.

[0065] According to the active sliding door mechanism 7 of this application, a first guide rail 710 and a second guide rail 705 are provided on both sides of the first base. A first slider 715 and a second slider 709 are slidably provided on the first guide rail 710 and the second guide rail 705, respectively. The first slider 715 and the second slider 709 can slide synchronously along their respective guide rails under the cooperation of the connecting member and the rotating support member 716, and the sliding directions are opposite. The first slider 715 is connected to the housing 1 through the traction mechanism, and the second slider 709 is connected to the door panel 21 provided on the outside of the housing door 2, so that when the housing door 2 rotates, the housing 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 housing door 2, so that the door panel 21 can avoid obstacles on both sides during the rotation and opening of the housing door 2.

[0066] It should be noted that, in practical applications, the design of the first slider 715, the second slider 709, and other sliders in this application can be flexible and varied 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.

[0067] From a material perspective, the first slider 715, the second slider 709, and other sliders in this application can be made of materials with high wear resistance, low coefficient of friction, and good stability, such as metal alloys, engineering plastics, or special lubricating materials. These material choices aim to improve the durability of the sliders, reduce wear and noise during sliding, and ensure smooth sliding.

[0068] In terms of structural design, the first slider 715, the second slider 709, and other sliders in this application can adopt various forms of guide rail contact surfaces, such as planar contact, ball contact, or sliding bearing contact. Each of these different contact methods has its advantages and disadvantages. For example, ball contact can reduce friction and wear, but it is more expensive; while planar contact has a simple structure, but may require more frequent lubrication and maintenance. Therefore, factors such as usage conditions, cost-effectiveness, and ease of maintenance should be comprehensively considered when making a selection.

[0069] In one embodiment of this application, as shown in Figures 1 and 2, the 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 first slider 715, and the second rotating shaft fixing seat 701 is used to connect to the housing 1. One end of the traction rod 702 is rotatably connected to the first rotating shaft fixing seat 713, and the other end of the traction rod 702 is rotatably connected to the second rotating shaft fixing seat 701.

[0070] In this embodiment, by fixing the first rotating shaft fixing seat 713 and the second rotating shaft fixing seat 701 to the first slider 715 and the box body 1 respectively, and connecting the first rotating shaft fixing seat 713 and the second rotating shaft fixing seat 701 through the traction rod 702, the distance between the first slider 715 and the second rotating shaft fixing seat 701 remains constant. 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, thereby pulling the first slider 715 through the transmission connection of the traction rod 702, the first rotating shaft fixing seat 713 and the second rotating shaft fixing seat 701, causing the first slider 715 to slide on the first base, and driving the second slider 709 to slide, so as to realize the movement of the door panel 21 relative to the box door 2.

[0071] Specifically, one end of the traction rod 702 is rotatably connected to the first rotating shaft fixing seat 713 via a pin 703, and the other end is rotatably connected to the second rotating shaft fixing seat 701 via another pin 703.

[0072] Specifically, in one embodiment of this application, as shown in Figures 1 and 2, two rotating support members 716 are provided, namely a first rotating support member and a second rotating support member respectively disposed at both ends of the first base. The connecting members include a first connecting member 706 and a second connecting member 712. The first connecting member 706 bypasses one end of the first base, a portion of which presses against the first rotating support member, and its two ends are respectively connected to one end of the first slider 715 and the second slider 709; the second connecting member 712 bypasses the other end of the first base, a portion of which presses against the second rotating support member, and its two ends are respectively connected to the other ends of the first slider 715 and the second slider 709.

[0073] In this embodiment, by connecting the first connector 706 around one end of the first base to the first slider 715 and the second slider 709 respectively, and pressing a portion of the first connector 706 onto the first rotating support, the first connector 706 is tightened. When the first slider 715 slides away from the first base under the drive of the housing 1 and the traction mechanism, the first slider 715 drives the second slider 709 to slide closer to the first base via the first connector 706. Simultaneously, by connecting the second connector 712 around the other end of the first base to the first slider 715 and the second slider 709 respectively, and pressing a portion of the first connector 706 onto the first rotating support, the first connector 706 is tightened. A portion of the connector 712 is pressed onto the second rotating support, taut the second connector 712. When the first slider 715 slides away from the first base under the drive of the housing 1 and the traction mechanism, the first slider 715 drives the second slider 709 to slide towards the other end closer to the first base through the second connector 712. This achieves that when the first slider 715 slides towards both ends of the first base, the second slider 709 can be driven to slide in the opposite direction to the first slider 715. This allows the door panel 21 to slide relative to the housing door 2 as the housing door 2 rotates when the housing door 2 is opened and closed, so as to avoid interference with obstacles and affect the opening and closing of the housing door 2.

[0074] In one embodiment of this application, as shown in Figures 1 and 2, the active sliding door mechanism 7 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 forms a first limiting groove. The two ends of the first limiting groove are connected to one end of the first guide rail 710 and the second guide rail 705. A first rotating support member is rotatably disposed in the first limiting groove, and a portion 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 forms a second limiting groove. The two ends of the second limiting groove are connected to the other ends of the first guide rail 710 and the second guide rail 705. A second rotating support member is rotatably disposed in the second limiting groove, and a portion of the second connecting member 712 is slidably disposed in the second limiting groove.

[0075] In this embodiment, a first fixed seat 704 and a second fixed seat 711 are respectively provided at both ends of the first base. The first fixed seat 704 and the second fixed seat 711 are respectively formed with a first limiting groove and a second limiting groove that mate with the first guide rail 710 and the second guide rail 705. The first limiting groove and the second limiting groove are respectively used to set the first rotating support and the second rotating support, so as to limit and guide the position of the first connector 706 and the second connector 712 respectively, to prevent the first connector 706 and the second connector 712 from slipping off the corresponding rotating support 716, so that the sliding of the first connector 706 and the second connector 712 is smoother and more stable. Meanwhile, both the first rotating support and the second rotating support can rotate with the sliding of the first connecting member 706 and the second connecting member 712, so that the friction between the first rotating support and the first connecting member 706, the second rotating support and the second connecting member 712 is rolling friction, which reduces the friction and wear on the first connecting member 706 and the second connecting member 712, making the sliding of the two connecting members smoother and helping to extend the service life of the connecting members.

[0076] In one embodiment of this application, the first limiting groove includes a first limiting sub-groove, a second limiting sub-groove, and a third limiting sub-groove that are bent and connected in sequence; the second limiting groove includes a fourth limiting sub-groove, a fifth limiting sub-groove, and a sixth limiting sub-groove that are bent and connected in sequence; both ends of the first connecting member 706 pass through the first limiting sub-groove, the second limiting sub-groove, and the third limiting sub-groove in sequence, and are connected to one end of the first slider 715 and the second slider 709; both ends of the second connecting member 712 pass through the fourth limiting sub-groove, the fifth limiting sub-groove, and the sixth limiting sub-groove in sequence, and are connected to the other end of the first slider 715 and the second slider 709.

[0077] In this embodiment, the first, second, and third limiting sub-slots are sequentially bent and connected, allowing the first limiting sub-slot to be wound around one end of the first base, enabling the first connector 706 to pass through the first limiting sub-slot and connect to one end of the first slider 715 and the second slider 709. This also allows the first limiting sub-slot to better limit the positioning of the first connector 706. Similarly, the fourth, fifth, and sixth limiting sub-slots are sequentially bent and connected, allowing the second limiting sub-slot to be wound around the other end of the first base, enabling the second connector 712 to pass through the second limiting sub-slot and connect to the other end of the first slider 715 and the second slider 709. This also allows the second limiting sub-slot to better limit the positioning of the second connector 712. Furthermore, this design makes the structure of the first limiting sub-slot, the second limiting sub-slot, and the first base more compact.

[0078] Specifically, in one embodiment of this application, there are two first rotating support members and two second rotating support members; one first rotating support member is disposed at the junction of the first limiting sub-groove and the second limiting sub-groove, and the other first rotating support member is disposed at the junction of the second limiting sub-groove and the third limiting sub-groove; one second rotating support member is disposed at the junction of the fourth limiting sub-groove and the fifth limiting sub-groove, and the other second rotating support member is disposed at the junction of the fifth limiting sub-groove and the sixth limiting sub-groove.

[0079] In this application, by respectively setting two first rotating supports at the transition points of the first and second limiting sub-slots, and the second and third limiting sub-slots, the first connecting member 706 is supported at the two transition points, reducing direct contact between the first connecting member 706 and the walls of each limiting sub-slot, especially at corner positions, thus reducing wear caused by contact between the first connecting member 706 and the sub-slot walls. Similarly, by respectively setting two second rotating supports at the transition points of the fourth and fifth limiting sub-slots, and the fifth and sixth limiting sub-slots, the second connecting member 712 is supported at the two transition points, which also reduces direct contact between the second connecting member 712 and the walls of each limiting sub-slot, thus reducing wear caused by contact between the second connecting member 712 and the sub-slot walls.

[0080] Specifically, in one embodiment of this application, both the first rotating support and the second rotating support include a rotating shaft 7161 and a roller 7162. The rotating shaft 7161 of the first rotating support is disposed in a first limiting groove, and the roller 7162 of the first rotating support is rotatably disposed on its rotating shaft 7161. A portion of the first connecting member 706 presses against the roller 7162 of the first rotating support. The rotating shaft 7161 of the second rotating support is disposed in a second limiting groove, and the roller 7162 of the second rotating support is rotatably disposed on its rotating shaft 7161. A portion of the second connecting member 712 presses against the roller 7162 of the second rotating support.

[0081] In this embodiment, the rotating shafts 7161 of the first and second rotating supports are respectively disposed in the first and second limiting grooves, and the corresponding rollers 7162 are rotatably disposed on the rotating shafts 7161, allowing the rollers 7162 to rotate freely on the rotating shafts 7161. Simultaneously, by pressing a portion of the first connecting member 706 and a portion of the second connecting member 712 onto the rollers 7162 of the first and second rotating supports respectively, when the first connecting member 706 and the second connecting member 712 slide relative to the rollers 7162, the rollers 7162 can slide along with them and rotate on the corresponding rotating shafts 7161. This transforms the friction between the first connecting member 706 and the rollers 7162, and between the second connecting member 712 and the rollers 7162, into rolling friction, thereby reducing wear between the first connecting member 706 and the rollers 7162, and between the second connecting member 712 and the rollers 7162, and extending their service life.

[0082] Specifically, the first fixed seat 704 is provided with a first fixed hole, and the first base is provided with a first waist-shaped hole extending along the width direction of the first base; the active sliding door mechanism 7 also includes a first adjusting member, which passes through the first fixed hole and is slidably disposed in the first waist-shaped hole, so as to adjust the tightness of the first connecting member 706 by adjusting the position of the first adjusting member in the first waist-shaped hole.

[0083] In this embodiment, by adjusting the position of the first adjusting member in the first waist-shaped hole, the position of the first fixing seat 704 can be adjusted along the width direction of the first base, so that the first fixing seat 704 can tighten or loosen the first connecting member 706, thereby adjusting the tightness of the first connecting member 706.

[0084] Since the first connector 706 and the second connector 712 are respectively located on the first fixed seat 704 and the second fixed seat 711 on both sides of the first base, and the first connector 706 and the second connector 712 are connected to the two ends of the first slider 715 and the second slider 709, when the first fixed seat 704 is adjusted to move relative to the first base through the first waist-shaped hole, the tightness of the first connector 706 is adjusted accordingly, and the tightness of the second connector 712 is also adjusted accordingly under the pull of the first fixed seat 704 on the first connector 706.

[0085] Understandably, the second fixed seat 711 may also be provided with a first fixed hole; the first base is provided with a first waist-shaped hole extending along the width direction of the first base; the active sliding door mechanism 7 also includes a first adjusting member, which passes through the first fixed hole and is slidably disposed in the first waist-shaped hole, so as to adjust the tightness of the second connecting member 712 by adjusting the position of the first adjusting member in the first waist-shaped hole.

[0086] In this embodiment, by adjusting the position of the first adjusting member in the first waist-shaped hole, the position of the second fixing seat 711 can be adjusted along the width direction of the first base, so that the second fixing seat 711 can tighten or loosen the second connecting member 712, thereby adjusting the tightness of the second connecting member 712.

[0087] Since the first connector 706 and the second connector 712 are respectively located on the first fixed seat 704 and the second fixed seat 711 on both sides of the first base, and the first connector 706 and the second connector 712 are connected to the two ends of the first slider 715 and the second slider 709, when the second fixed seat 711 is adjusted to move relative to the first base through the first waist-shaped hole, the second connector 712 adjusts its tightness accordingly, and the first connector 706 also adjusts its tightness accordingly under the pull of the second fixed seat 711 on the second connector 712.

[0088] Furthermore, in some embodiments, the first fixed base 704 is provided with a second oblong hole extending along the width direction of the first base. The first base is provided with a second fixing hole. The active sliding door mechanism 7 also includes a second adjusting member, which passes through the second oblong hole and the second fixing hole in sequence and is fixed in the external structure, so as to adjust the position of the first fixed base 704 relative to the external structure by the position of the second adjusting member in the second oblong hole.

[0089] In this embodiment, a second oblong hole is provided on the first fixed seat 704, and a second adjusting member is sequentially passed through the second oblong hole and the second fixed hole and fixed in the external structure, so as to fix the first fixed seat 704 in the external structure, so as to fix the active sliding door mechanism 7 on the external structure (such as the box door 2). At the same time, the second adjusting member can be finely adjusted along the position of the second oblong hole to adjust the position of the first fixed seat 704, thereby enabling adjustment of the position of the first fixed seat 704 relative to the external structure.

[0090] It is understood that the second fixing seat 711 may also be provided with a second oblong hole extending along the width direction of the first base; the second adjusting member passes through the second oblong hole and the second fixing hole in sequence and is fixed in the external structure so as to adjust the position of the second fixing seat 711 relative to the external structure by the position of the second adjusting member in the second oblong hole. The functions of the second adjusting member, the second oblong hole and the second fixing hole are similar to those in the above embodiment, and will not be repeated here.

[0091] In one embodiment of this application, as shown in Figures 1 and 2, the first guide rail 710 and the second guide rail 705 are arranged in parallel, and the first guide rail 710 and the second guide rail 705 are respectively arranged on opposite sides of the first base.

[0092] In this embodiment, the first guide rail 710 and the second guide rail 705 are arranged in parallel. This ensures that the first slider 715 and the second slider 709 have sufficient sliding stroke while reducing the size of the active sliding door mechanism 7 along the length of the guide rail, making the entire mechanism more compact. At the same time, by setting the first guide rail 710 and the second guide rail 705 on opposite sides of the first base, the first slider 715 and the second slider 709 can maintain a certain distance when sliding relative to each other, avoiding interference between them. The structure is simple, convenient and practical.

[0093] In another embodiment of this application, as shown in Figures 3 and 4, a door assembly is provided, including: a door 2, a door panel 21, and an active sliding door mechanism 7 as provided in any of the above embodiments. The door 2 is rotatably connected to a housing 1 and is adapted to open or close the storage space of the housing 1. The door panel 21 is slidably disposed on the outside of the door 2; the active sliding door mechanism 7 is disposed on the door 2, a first slider 715 is connected to the housing 1 via a traction mechanism, and a second slider 709 is connected to the door panel 21. During the opening or closing of the door 2, the 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 door 2.

[0094] Understandably, the width direction of the door 2 is parallel to the plane on which the door 2 is located and perpendicular to the rotation axis of the door 2, so that the door panel 21 can move away from or close to the rotation axis of the door 2 (as shown by the double-headed arrows in Figure 3). It should be noted that the parallel and perpendicular relationships in this application need to take into account the installation errors between various components, and an error of ±10° should be understood as being within the scope of protection of the patent.

[0095] Specifically, during the process of the door 2 rotating outwards from the box body 1 (as shown by the arc arrow in Figure 3), the first slider 715 slides towards the first hinge 4 under the drive of the box body 1 and the traction mechanism. The first slider 715, through the cooperation of the connecting piece and the rotating support piece 716, drives the second slider 709 to slide away from the first hinge 4, thereby driving the door panel 21 to slide away from the first hinge 4, thus preventing the door panel 21 from interfering with obstacles on the outside. Similarly, during the process of the door 2 rotating to one side of the box body 1 to close, the active sliding door mechanism 7 drives the door panel 21 to slide towards the first hinge 4, thereby preventing the closed door panel 21 from interfering with obstacles.

[0096] According to the door assembly of the present application embodiment, an active sliding door mechanism 7 is provided on the door 2. The active sliding door mechanism 7 is connected to the box body 1 and the door panel 21 respectively, so that when the door 2 rotates to open or close relative to the box body 1, the door panel 21 is driven to slide relative to the width direction of the door 2, so that the door panel 21 can avoid obstacles such as side walls and objects when the door 2 is closed or opened.

[0097] It is understood that since the active sliding door mechanism 7 has the beneficial effects of the above embodiments, the door assembly will have the corresponding beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and will not be repeated in this application.

[0098] In one embodiment of this application, as shown in Figures 4 and 5, the door assembly further includes a driven sliding door mechanism 8, which 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 disposed on the third guide rail and connected to the door panel 21.

[0099] In this embodiment, a driven sliding door mechanism 8 is provided on the cabinet door 2. The driven sliding door mechanism 8 has a second base 817, on which a third guide rail and a third slider 813 that can slide along the third guide rail are provided. The third slider 813 is connected to the door panel 21. The third slider 813 can slide with the door panel 21 when the door panel 21 slides relative to the cabinet door 2, providing support and assistance for the sliding of the door panel 21, making the sliding of the door panel 21 smoother relative to the cabinet door 2. At the same time, the driven sliding door mechanism 8 can cooperate with the active sliding door mechanism 7 to restrict the movement direction of the door panel 21, reducing the shaking of the door panel 21 during the sliding process and making the sliding more stable.

[0100] Optionally, there may be multiple driven sliding door mechanisms 8. Some of the driven sliding door mechanisms 8 may be coaxially mounted on the door 2 with the driving sliding door mechanism 7; other driven sliding door mechanisms 8 may be coaxially mounted on the door 2 with the driving sliding door mechanism 7.

[0101] Specifically, the driven sliding door mechanism 8 and the active sliding door mechanism 7 are coaxially arranged, meaning they share the same centerline or axis. This helps ensure that the door panel 21 maintains stable linear movement during sliding, reducing the possibility of deviation or swaying. Coaxial arrangement is used in situations where precise control of the direction of movement or maintaining the relative positional relationship between components is required.

[0102] The driven sliding door mechanism 8 and the active sliding door mechanism 7 are arranged on opposite axes, meaning they do not share the same centerline or axis. This configuration is used to provide additional support, stability, or to prevent the door panel 21 from deflecting around the sliding direction during sliding. The off-axis arrangement is used in situations requiring distributed force, increased stability, or the implementation of complex motion trajectories.

[0103] In another embodiment of this application, as shown in Figures 3 and 4, a refrigeration device is provided, including: a housing 1 and a door assembly as provided in any of the above embodiments. The housing 1 forms a storage space, and a door 2 is rotatably connected to the housing 1, adapted to open or close the storage space.

[0104] In this embodiment, the door assembly includes: a door 2, a door panel 21, and an active sliding door mechanism 7. The active sliding door mechanism 7 is disposed on the door 2 and is configured to drive the door panel 21 to move relative to the width direction of the door 2 during the opening or closing of the door 2.

[0105] By setting a door panel 21 on the cabinet door 2, when the refrigeration equipment is embedded and set in a recessed space, or when it is set between two cabinets, the door panel 21 can be set flush with the cabinets on the side wall or sides of the recess, so as to reduce the gap between the refrigeration equipment and the adjacent wall or cabinet, making it more aesthetically pleasing.

[0106] Meanwhile, when the cabinet door 2 rotates, the active sliding door mechanism 7 can drive the door panel 21 to move relative to the cabinet door 2 during the rotation process, so as to move away from the wall or cabinet of the side door of the cabinet 1 as much as possible, so as to avoid these obstacles blocking the door panel 21 and affecting the rotation of the cabinet door 2, causing the cabinet door 2 to be unable to open or close normally.

[0107] The combination of door 2 and door panel 21 prevents interference between the door panel 21 and surrounding objects when the refrigeration equipment is opened and closed, greatly improving ease of use. This design advantage is particularly evident in confined kitchen environments. Furthermore, the sliding door mechanism 7 incorporates a slider, guide rail, and ball bearings between them, enabling the door panel 21 to move smoothly and seamlessly during opening and closing, thus enhancing the refrigerator's lifespan and stability.

[0108] It is understood that if the door assembly has the beneficial effects of the above embodiments, then the refrigeration equipment will have the corresponding beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and will not be repeated in this application.

[0109] Understandably, there can be multiple storage spaces.

[0110] Understandably, multiple storage spaces can be arranged arbitrarily, such as vertically or horizontally. Storage conditions can be set for these spaces according to storage needs; for example, some spaces can be designated as refrigerators, while others can be designated as freezers.

[0111] As shown in Figure 3, an application scenario based on the above embodiment is as follows: A refrigeration device can be installed in a slotted structure in the middle of a cabinet. A door panel 21 is provided on the outer side of the cabinet door 2 of the refrigeration device's cabinet body 1. The material and color of the door panel 21 can be designed to be similar to or the same as the material and 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 edge of the slotted structure opening, and fits as close as possible to the opening of the slotted structure, so that the door panel 21 and the outer wall of the cabinet maintain visual consistency and have minimal gaps, making it more aesthetically pleasing.

[0112] When the cabinet door 2 is rotated outward to open, the active sliding door mechanism 7 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 on the side closer to the first hinge 4, which would prevent the cabinet door 2 from opening to a larger angle. When the cabinet door 2 is rotated to close, the active sliding door mechanism 7 drives the door panel 21 to slide closer to the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall on the side away from the first hinge 4, which would prevent the cabinet door 2 from closing completely and affecting the refrigeration and preservation effect in the storage space. Furthermore, when the cabinet door 2 is fully closed, the door panel 21 can return to a state flush with the cabinet body.

[0113] In one embodiment of this application, as shown in FIG4, the cabinet 1 has a first storage space and a second storage space. There are two door assemblies, namely a first door assembly and a second door assembly. The door 2 of the first door assembly is rotatably connected to the cabinet 1 to open or close the first storage space, and the door 2 of the second door assembly is rotatably connected to the cabinet 1 to open or close the second storage space.

[0114] In this embodiment, by providing a first storage space and a second storage space on the housing 1, the items to be stored can be stored separately according to requirements. The first storage space and the second storage space are respectively provided with a first door assembly and a second door assembly, so that when the doors 2 of the first door assembly and the second door assembly are rotated and opened, the corresponding door panels 21 can slide relative to the doors 2 to avoid obstacles.

[0115] Finally, it should be noted that the above embodiments are for illustrative purposes only and are not intended to limit the scope of this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the scope of the technical solutions of this application and should be covered by the scope of the claims of this application.
