[0061] The following will describe the active sliding door mechanism, door body assembly, and refrigeration device of the present application in conjunction with Figures 1 to 5 Describe the active sliding door mechanism, door body assembly, and refrigeration device of the present application. The active sliding door mechanism and door body assembly in the present application can be applied to the cabinet doors or box doors of household appliances, such as the box door of a refrigerator. However, it should be understood that the door panel mechanism and door body assembly of the present application can also be applied to dishwashers, washing machines, or any other suitable devices. The refrigeration device in the present application is, for example, applied as a refrigerator. However, it should be understood that the refrigeration device of the present application can also be applied as a freezer or any other suitable device.

[0062] In one embodiment of the present application, as Figures 1 to 4 shown, the active sliding door mechanism 7 is applied to a refrigeration device. The refrigeration device includes: a box body 1, a box door 2, and a door panel 21. The box door 2 is rotatably arranged on the box body 1, and a door panel 21 that can slide along it is provided on the outer side of the box door 2. The active sliding door mechanism 7 includes: a first base for being arranged on the box door 2. A first guide rail 710 is formed on one side of the first base, and a second guide rail 705 is formed on the other side; a first slider 715 and a traction mechanism. The first slider 715 is slidably arranged on the first guide rail 710; the first slider 715 is connected to the box body 1 through the traction mechanism; a second slider 709 is slidably arranged on the second guide rail 705, and the second slider 709 is used to connect to the door panel 21; a connecting member and a rotating support member 716. The two ends of the connecting member are respectively connected to the first slider 715 and the second slider 709, and a part of the connecting member is pressed on the rotating support member 716; in the case where the first slider 715 moves on the first guide rail 710, the first slider 715 drives the connecting member to move on the rotating support member 716, so as to drive the second slider 709 to move in the opposite direction on the second guide rail 705 through the connecting member.

[0063] The first base of this embodiment can be arranged on the box door 2. The connecting member can be a connecting component such as a traction rope or a transmission belt. The two ends of the connecting member are respectively connected to the first slider 715 and the second slider 709, so that the first slider 715 can drive the second slider 709 to move synchronously, and further drive the door panel 21 to slide relative to the box door 2.

[0064] By setting a rotatable rotating support 716, a part of the connecting member is pressed on the rotating support 716, so as to tighten the connecting member while adjusting the extension and movement direction of the connecting member, so that when the first slider 715 moves along the first guide rail 710, the second slider 709 can be driven by the connecting member to move on the second guide rail 705, and the movement direction of the second slider 709 is opposite to that of the first slider 715, so as to drive the door panel 21 to avoid obstacles.

[0065] Specifically, during the process of the box door 2 rotating outward to open relative to the box body 1, the box body 1 drives the first slider 715 to slide towards the direction close to the first hinge 4 through the traction mechanism. At the same time, the first slider 715 drives the second slider 709 to slide in the opposite direction (i.e., away from the first hinge 4) through the connecting member, thereby preventing the door panel 21 from interfering with the obstacles outside. During the process of the box door 2 rotating towards one side of the box body 1 to close, the box body 1 drives the first slider 715 to slide away from the first hinge 4 through the traction mechanism. At the same time, the first slider 715 drives the second slider 709 to slide in the opposite direction (i.e., towards the first hinge 4) through the connecting member, thereby preventing the door panel 21 from interfering with the obstacles after closing.

[0066] According to the active sliding door mechanism 7 of the present application, by arranging the first guide rail 710 and the second guide rail 705 on both sides of the first base, the first slider 715 and the second slider 709 are respectively slidably arranged on the first guide rail 710 and the second guide rail 705. The first slider 715 and the second slider 709 can synchronously slide along the respective guide rails under the combined drive of the connecting member and the rotating support 716, and the sliding directions are opposite. The first slider 715 is connected to the box body 1 through the traction mechanism, and the second slider 709 is connected to the door panel 21 arranged outside the box door 2, so that when the box door 2 rotates, the box body 1 drives the two sliders to slide relatively through the traction mechanism and the connecting member, so as to drive the door panel 21 to slide relative to the box door 2, so that the door panel 21 can avoid the obstacles on both sides during the process of the box door 2 rotating to open and close.

[0067] It should be noted that in practical applications, the designs of the first slider 715, the second slider 709 and other sliders in the present application can be flexible and variable to adapt to different working scenarios and performance requirements. They are not limited to specific shapes, sizes or materials, but can be customized and optimized according to specific needs.

[0068] 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 friction coefficient, and good stability, such as metal alloys, engineering plastics, or special lubricating materials. The selection of these materials aims to improve the durability of the sliders, reduce wear and noise during sliding, and ensure smooth sliding.

[0069] 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 plane contact, ball contact, or sliding bearing contact, etc. These different contact methods have their own advantages and disadvantages. For example, ball contact can reduce friction and wear, but the cost is relatively high; while plane contact has a simple structure, but may require more frequent lubrication and maintenance. Therefore, when making a selection, factors such as usage conditions, cost-effectiveness, and maintenance convenience should be comprehensively considered.

[0070] In an embodiment of this application, as Figure 1 and Figure 2 shown, 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, the second rotating shaft fixing seat 701 is used to connect to the box body 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.

[0071] In this embodiment, by fixing the first rotating shaft fixing seat 713 and the second rotating shaft fixing seat 701 on the first slider 715 and the box body 1 respectively, and connecting them through the traction rod 702 between the first rotating shaft fixing seat 713 and the second rotating shaft fixing seat 701, the distance between the first slider 715 and the second rotating shaft fixing seat 701 is always kept unchanged. When the box door 2 rotates relative to the box body 1, the angle between the box body 1 and the box door 2 changes. Thus, through the transmission connection of the traction rod 702, the first rotating shaft fixing seat 713, and the second rotating shaft fixing seat 701, the first slider 715 is pulled, causing the first slider 715 to slide on the first base and driving the second slider 709 to slide to realize the movement of the door panel 21 relative to the box door 2.

[0072] Specifically, one end of the traction rod 702 and the first rotating shaft fixing seat 713 are rotatably connected through a pin shaft 703, and the other end and the second rotating shaft fixing seat 701 are rotatably connected through another pin shaft 703.

[0073] Specifically, in an embodiment of this application, as Figure 1 and Figure 2As shown, there are two rotating supports 716, namely a first rotating support and a second rotating support respectively arranged at both ends of the first base. The connecting member includes a first connecting member 706 and a second connecting member 712. The first connecting member 706 bypasses one end of the first base, a part of the first connecting member 706 is pressed on the first rotating support, and both 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 part of the second connecting member 712 is pressed on the second rotating support, and both ends are respectively connected to the other end of the first slider 715 and the second slider 709.

[0074] In this embodiment, by bypassing one end of the first base with the first connecting member 706 and connecting it to the first slider 715 and the second slider 709 respectively, and pressing a part of the first connecting member 706 on the first rotating support to tighten the first connecting member 706. When the first slider 715 slides away from this end of the first base under the drive of the box body 1 and the traction mechanism, the first slider 715 drives the second slider 709 to slide towards this end of the first base through the first connecting member 706; at the same time, by bypassing the other end of the first base with the second connecting member 712 and connecting it to the first slider 715 and the second slider 709 respectively, and pressing a part of the second connecting member 712 on the second rotating support to tighten the second connecting member 712. When the first slider 715 slides away from the other end of the first base under the drive of the box body 1 and the traction mechanism, the first slider 715 drives the second slider 709 to slide towards the other end of the first base through the second connecting member 712. Thus, when the first slider 715 slides towards both ends of the first base respectively, it can drive the second slider 709 to slide in the opposite direction to the first slider 715, and further enable the door panel 21 to slide relative to the box door 2 as the box door 2 rotates 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.

[0075] In an embodiment of the present application, as Figure 1 and Figure 2 shown, 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, forming a first limiting groove. Both ends of the first limiting groove are butted against one end of the first guide rail 710 and the second guide rail 705. The first rotating support is rotatably arranged in the first limiting groove, and a part of the first connecting member 706 is slidably arranged in the first limiting groove; the second fixed seat 711 is connected to the other end of the first base, forming a second limiting groove. Both ends of the second limiting groove are butted against the other end of the first guide rail 710 and the second guide rail 705. The second rotating support is rotatably arranged in the second limiting groove, and a part of the second connecting member 712 is slidably arranged in the second limiting groove.

[0076] In this embodiment, by respectively arranging a first fixing seat 704 and a second fixing seat 711 at both ends of the first base, a first limiting groove and a second limiting groove for docking with the first guide rail 710 and the second guide rail 705 are respectively formed on the first fixing seat 704 and the second fixing seat 711. The first limiting groove and the second limiting groove are respectively used for arranging a first rotating support and a second rotating support to respectively limit and guide the positions of the first connecting piece 706 and the second connecting piece 712, so as to prevent the first connecting piece 706 and the second connecting piece 712 from slipping off the corresponding rotating support 716, and make the sliding of the first connecting piece 706 and the second connecting piece 712 smoother and more stable. At the same time, both the first rotating support and the second rotating support can rotate along with the sliding of the first connecting piece 706 and the second connecting piece 712, so that the frictional force between the first rotating support and the first connecting piece 706, and between the second rotating support and the second connecting piece 712 is rolling frictional force, reducing the frictional force and wear suffered by the first connecting piece 706 and the second connecting piece 712, making the sliding of the two connecting pieces smoother, and being beneficial to extending the service life of the connecting pieces.

[0077] In an embodiment of the present application, the first limiting groove includes a first limiting sub-groove, a second limiting sub-groove and a third limiting sub-groove that are sequentially bent and communicated; the second limiting groove includes a fourth limiting sub-groove, a fifth limiting sub-groove and a sixth limiting sub-groove that are sequentially bent and communicated; both ends of the first connecting piece 706 sequentially pass through the first limiting sub-groove, the second limiting sub-groove and the third limiting sub-groove and are connected to one ends of the first slider 715 and the second slider 709; both ends of the second connecting piece 712 sequentially pass through the fourth limiting sub-groove, the fifth limiting sub-groove and the sixth limiting sub-groove and are connected to the other ends of the first slider 715 and the second slider 709.

[0078] In this embodiment, the first limiting sub-groove, the second limiting sub-groove and the third limiting sub-groove are sequentially bent and communicated, so that the first limiting groove can be wound around one end of the first base, enabling the first connecting piece 706 to pass through the first limiting groove and be connected to one ends of the first slider 715 and the second slider 709, and at the same time enabling the first limiting groove to better limit the first connecting piece 706; similarly, the fourth limiting sub-groove, the fifth limiting sub-groove and the sixth limiting sub-groove are sequentially bent and communicated, so that the second limiting groove can be wound around the other end of the first base, enabling the second connecting piece 712 to pass through the second limiting groove and be connected to the other ends of the first slider 715 and the second slider 709, and enabling the second limiting groove to better limit the second connecting piece 712. At the same time, the structures of the first limiting groove, the second limiting groove and the first base are made more compact.

[0079] Specifically, in an embodiment of the present application, there are two first rotating supports and two second rotating supports; one of the first rotating supports is disposed at the transition between the first limiting sub-slot and the second limiting sub-slot, and the other first rotating support is disposed at the transition between the second limiting sub-slot and the third limiting sub-slot; one of the second rotating supports is disposed at the transition between the fourth limiting sub-slot and the fifth limiting sub-slot, and the other second rotating support is disposed at the transition between the fifth limiting sub-slot and the sixth limiting sub-slot.

[0080] In the present application, by respectively disposing the two first rotating supports at the transitions between the first limiting sub-slot and the second limiting sub-slot, and between the second limiting sub-slot and the third limiting sub-slot, so as to support the first connecting member 706 at the two transitions, reducing the direct contact between the first connecting member 706 and the slot walls of each limiting sub-slot, especially the slot walls at the corner positions, and reducing the wear generated by the contact between the first connecting member 706 and the slot walls. Similarly, by respectively disposing the two second rotating supports at the transitions between the fourth limiting sub-slot and the fifth limiting sub-slot, and between the fifth limiting sub-slot and the sixth limiting sub-slot, so as to support the second connecting member 712 at the two transitions, the direct contact between the second connecting member 712 and the slot walls of each limiting sub-slot can also be reduced, and the wear generated by the contact between the second connecting member 712 and the slot walls can be reduced.

[0081] Specifically, in an embodiment of the present 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 the first limiting slot, the roller 7162 of the first rotating support is rotatably disposed on its rotating shaft 7161, and a part of the first connecting member 706 is pressed on the roller 7162 of the first rotating support. The rotating shaft 7161 of the second rotating support is disposed in the second limiting slot, the roller 7162 of the second rotating support is rotatably disposed on its rotating shaft 7161, and a part of the second connecting member 712 is pressed on the roller 7162 of the second rotating support.

[0082] In this embodiment, the rotating shafts 7161 of the first rotating support member and the second rotating support member are respectively arranged in the first limiting groove and the second limiting groove, and the corresponding rollers 7162 are rotatably arranged on the rotating shafts 7161, and the rollers 7162 can rotate freely on the rotating shafts 7161. At the same time, by pressing a part of the first connecting member 706 and the second connecting member 712 on the rollers 7162 of the first rotating support member and the rollers 7162 of the second rotating support member respectively, when the first connecting member 706 and the second connecting member 712 slide relative to the rollers 7162, the rollers 7162 can rotate on the corresponding rotating shafts 7161 along with the sliding, so that the frictional force between the first connecting member 706 and the rollers 7162, and between the second connecting member 712 and the rollers 7162 is rolling friction, thereby reducing the wear between the first connecting member 706 and the rollers 7162, and between the second connecting member 712 and the rollers 7162, and prolonging the service life.

[0083] Specifically, the first fixing seat 704 is provided with a first fixing 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 further includes a first adjusting member, the first adjusting member passes through the first fixing hole and is slidably arranged 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.

[0084] 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.

[0085] Since the first connecting member 706 and the second connecting member 712 are respectively located on the first fixing seat 704 and the second fixing seat 711 on both sides of the first base, and the first connecting member 706 and the second connecting member 712 are connected to both ends of the first slider 715 and the second slider 709, when the position of the first fixing seat 704 relative to the first base is adjusted through the first waist-shaped hole, the tightness of the first connecting member 706 is correspondingly adjusted, and the second connecting member 712 is also correspondingly adjusted in tightness under the pulling of the first fixing seat 704 on the first connecting member 706.

[0086] It can be understood that the second fixing seat 711 can also be provided with a first fixing 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 further includes a first adjusting member, the first adjusting member passes through the first fixing hole and is slidably arranged 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.

[0087] 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 tension or relax the second connecting member 712, thereby adjusting the tightness of the second connecting member 712.

[0088] Since the first connecting member 706 and the second connecting member 712 are respectively located on the first fixing seat 704 and the second fixing seat 711 on both sides of the first base, and the first connecting member 706 and the second connecting member 712 are connected to both ends of the first slider 715 and the second slider 709, when the second fixing seat 711 is adjusted to move relative to the first base through the first waist-shaped hole, the tightness of the second connecting member 712 is correspondingly adjusted, and the first connecting member 706 is also correspondingly adjusted in tightness under the pulling of the second fixing seat 711 on the second connecting member 712.

[0089] Further, in some embodiments, the first fixing seat 704 is provided with a second waist-shaped 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 further includes a second adjusting member, and the second adjusting member passes through the second waist-shaped hole and the second fixing hole in sequence and is fixed in the external structure, so as to adjust the position of the first fixing seat 704 relative to the external structure by the position of the second adjusting member in the second waist-shaped hole.

[0090] In this embodiment, by providing the second waist-shaped hole on the first fixing seat 704 and fixing the second adjusting member through the second waist-shaped hole and the second fixing hole in sequence in the external structure, the first fixing seat 704 can be fixed 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 in the position along the second waist-shaped hole, so as to adjust the position of the first fixing seat 704, so as to be able to cooperate to adjust the position of the first fixing seat 704 relative to the external structure.

[0091] It can be understood that the second fixing seat 711 can also be provided with a second waist-shaped hole extending along the width direction of the first base; the second adjusting member passes through the second waist-shaped 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 waist-shaped hole. The functions of the second adjusting member, the second waist-shaped hole and the second fixing hole are similar to those in the above embodiments, and will not be described in detail here.

[0092] In an embodiment of the present application, as Figure 1 and Figure 2 shown, 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 two opposite sides of the first base.

[0093] In this embodiment, the first guide rail 710 and the second guide rail 705 are arranged in parallel, which is beneficial to reducing the size of the active sliding door mechanism 7 along the length direction of the guide rail while ensuring that the first slider 715 and the second slider 709 have sufficient sliding stroke, making the entire mechanism more compact; at the same time, by respectively arranging the first guide rail 710 and the second guide rail 705 on two sides of the first base away from each other, the first slider 715 and the second slider 709 can maintain a certain distance when sliding relative to each other, avoiding interference between the two, and the structure is simple, convenient and practical.

[0094] In another embodiment of the present application, Figure 3 and Figure 4 As shown, a door assembly is provided, comprising: a box door 2, a door panel 21, and an active sliding door mechanism 7 provided in any of the above embodiments. The box door 2 is rotatably connected to the box body 1, and is suitable for opening or closing the storage space of the box body 1. The door panel 21 is slidably arranged on the outside of the box door 2; the active sliding door mechanism 7 is arranged on the box door 2, the first slider 715 is transmission-connected to the box body 1 through a traction mechanism, and the second slider 709 is connected to the door panel 21. In the process of opening or closing the box 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 box door 2.

[0095] It is understandable that the width direction of the door 2 is parallel to the plane where the door 2 is located and perpendicular to the rotation axis of the door 2, so that the door panel 21 can be away from or close to the rotation axis of the door 2 (such as Figure 3 It should be noted that the parallel and perpendicular relationship of the present application needs to take into account the installation error between the various components, and the error of plus or minus 10° should be understood as the scope of protection of the patent.

[0096] Specifically, during the process of the door 2 rotating toward the outside of the box body 1 to open (eg Figure 3 In the embodiment shown in the curved arrow in the figure, the first slider 715 slides in the direction close to the first hinge 4 under the drive of the box body 1 and the traction mechanism, and the first slider 715 drives the second slider 709 to slide in the direction away from the first hinge 4 through the connection member and the rotation support member 716, thereby driving the door panel 21 to slide in the direction away from the first hinge 4, thereby avoiding the door panel 21 from interfering with the obstacles outside. Similarly, when the box door 2 rotates to one side of the box body 1 to close, the active sliding door mechanism 7 drives the door panel 21 to slide in the direction close to the first hinge 4, thereby avoiding the door panel 21 from interfering with the obstacles after closing.

[0097] For the door body assembly according to the embodiments of the present application, an active sliding door mechanism 7 is provided on the cabinet door 2. The active sliding door mechanism 7 is respectively connected to the cabinet body 1 and the door panel 21, so that during the process of the cabinet door 2 rotating relative to the cabinet body 1 to open or close, the door panel 21 is driven to slide in the width direction of the cabinet door 2, so that the door panel 21 can avoid obstacles such as side walls and objects during the closing or opening process of the cabinet door 2.

[0098] It can be understood that if the active sliding door mechanism 7 has the beneficial effects of the above embodiments, then the door body assembly 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 an embodiment of the present application, as Figure 4 and Figure 5 shown, the door body assembly further includes: a driven sliding door mechanism 8, and the driven sliding door mechanism 8 includes a second base 817 and a third slider 813; a third guide rail is formed on the second base 817, and the third slider 813 is slidably disposed on the third guide rail, and the third slider 813 is connected to the door panel 21.

[0100] In this embodiment, by providing the driven sliding door mechanism 8 on the cabinet door 2, the driven sliding door mechanism 8 has a second base 817, and a third guide rail and a third slider 813 that can slide along the third guide rail are provided on the second base 817. The third slider 813 is connected to the door panel 21. The third slider 813 can slide along with the door panel 21 when the door panel 21 slides relative to the cabinet door 2, playing a supporting and assisting role in the sliding of the door panel 21, making the sliding of the door panel 21 relative to the cabinet door 2 smoother. At the same time, the driven sliding door mechanism 8 can cooperate with the active sliding door mechanism 7 to limit the movement direction of the door panel 21, reducing the shaking generated during the sliding process of the door panel 21 and making the sliding more stable.

[0101] Optionally, there can be multiple driven sliding door mechanisms 8. Among them, some of the driven sliding door mechanisms 8 can be coaxially arranged with the active sliding door mechanism 7 on the cabinet door 2; the other part of the driven sliding door mechanisms 8 are arranged on the cabinet door 2 with the active sliding door mechanism 7 non-coaxially.

[0102] Specifically, the coaxial arrangement of the driven sliding door mechanism 8 and the active sliding door mechanism 7 means sharing the same center line or axis, which helps to ensure that the door panel 21 can maintain a stable linear motion during the sliding process, reducing the possibility of deviation or swing. The coaxial arrangement is used in occasions where precise control of the movement direction or maintaining the relative positional relationship between components is required.

[0103] The driven sliding door mechanism 8 is arranged with a different axis from the active sliding door mechanism 7, which means they do not share the same center line or axis. This configuration is used to provide additional support, stability or prevent the door panel 21 from deflecting around the sliding direction during the sliding process. The different-axis setting is used in situations where it is necessary to disperse forces, increase stability or achieve complex motion trajectories.

[0104] In an embodiment of another aspect of the present application, as Figure 3 and Figure 4 shown, a refrigeration device is provided, including: a box body 1 and a door body assembly as provided in any of the above embodiments. Among them, the box body 1 forms a storage space, and the box door 2 is rotatably connected to the box body 1 and is adapted to open or close the storage space.

[0105] In this embodiment, the door body assembly includes: a box door 2, a door panel 21 and an active sliding door mechanism 7. The active sliding door mechanism 7 is arranged on the box door 2 and is configured to drive the door panel 21 to move relative to the width direction of the box door 2 during the opening or closing process of the box door 2.

[0106] By arranging the door panel 21 on the box door 2, when the refrigeration device is an embedded type and is arranged in a groove-shaped space, or is arranged between two cabinets, the door panel 21 can be set flush with the side wall of the groove or the cabinets on both sides, so as to reduce the gap between the refrigeration device and the adjacent wall or cabinet, making it more beautiful.

[0107] At the same time, when the box door 2 rotates, the active sliding door mechanism 7 can drive the door panel 21 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 of the box door of the box body 1, so as to avoid these obstacles blocking the door panel 21 and affecting the rotation of the box door 2, resulting in the box door 2 being unable to be opened or closed normally.

[0108] The combination of the box door 2 and the door panel 21 enables the refrigeration device to avoid interference between the door panel 21 and surrounding objects when opening and closing, greatly improving the use convenience. Especially in a narrow kitchen environment, this design advantage is more obvious. In addition, the setting of the slider, guide rail and the ball between them in the active sliding door mechanism 7 enables the door panel 21 to move smoothly during the opening and closing processes, improving the service life and stability of the refrigerator.

[0109] 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 application will not be elaborated herein.

[0110] It can be understood that there can be multiple storage spaces.

[0111] It is understandable that multiple storage spaces can be arranged arbitrarily, such as arranged vertically, horizontally, etc. Multiple storage spaces can set storage conditions according to storage needs. For example, some storage spaces are set as refrigerators, and other storage spaces are set as freezers.

[0112] As Figure 3 shown, based on an application scenario of the above embodiment: The refrigeration device can be installed in a groove structure in the middle of a cabinet. A door panel 21 is arranged on the outer side of the door 2 of the box body 1 of the refrigeration device. The material and color of the door panel 21 can be designed to be similar to or the same as the material color of the outer wall of the cabinet. When the door 2 is closed, the door panel 21 is flush with the outer wall of the cabinet at the opening edge of the groove structure and fits as closely as possible to the opening of the groove structure, so that the door panel 21 and the outer wall of the cabinet can maintain visual consistency and have a small gap, which is more beautiful.

[0113] When the door 2 rotates 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 close to the first hinge 4, resulting in the door 2 being unable to open to a larger angle. When the door 2 rotates to close, the active sliding door mechanism 7 drives the door panel 21 to slide towards 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, resulting in the door 2 being unable to close completely and affecting the refrigeration preservation effect in the storage space. And when the door 2 is completely closed, the door panel 21 can return to a state flush with the cabinet body again.

[0114] In an embodiment of the present application, as Figure 4 shown, the box body 1 has a first storage space and a second storage space. There are two door body assemblies, namely the first door body assembly and the second door body assembly. The door 2 of the first door body assembly is rotatably connected to the box body 1 to open or close the first storage space, and the door 2 of the second door body assembly is rotatably connected to the box body 1 to open or close the second storage space.

[0115] In this embodiment, by setting a first storage space and a second storage space on the box body 1, the items to be stored are stored separately according to needs. The first storage space and the second storage space are respectively provided with a first door body assembly and a second door body assembly, so that when the doors 2 of the first door body assembly and the second door body assembly are rotated to open and close, the corresponding door panels 21 can slide relative to the doors 2 to avoid obstacles.

[0116] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered within the scope of the claims of the present invention.
