[0062] The following will describe the active sliding door mechanism, door body assembly, and refrigeration equipment of the present application in conjunction with Figures 1 to 5 The active sliding door mechanism and door body assembly in the present application can be applied to the cabinet doors or chamber doors of household appliances, such as the chamber 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 equipment. The refrigeration equipment in the present application is, for example, applied as a refrigerator. However, it should be understood that the refrigeration equipment of the present application can also be applied as a freezer or any other suitable equipment.

[0063] In one embodiment of the present application, as Figures 1 to 4 shown, the active sliding door mechanism 7 is applied to the refrigeration equipment. The refrigeration equipment includes: a cabinet 1, a chamber door 2, and a door panel 21. The chamber door 2 is rotatably arranged on the cabinet 1, and a door panel 21 that can slide along it is provided on the outer side of the chamber door 2. The active sliding door mechanism 7 includes: a first base for being arranged on the chamber 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 cabinet 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 be connected to the door panel 21; a connecting member, the two ends of which are respectively connected to the first slider 715 and the second slider 709; a first fixing seat 704 is movably connected to one end of the first base, and a first limiting groove is formed. The two ends of the first limiting groove are docked with one end of the first guide rail 710 and the second guide rail 705. A part of the connecting member is located in the first limiting groove to adjust the tightness of the connecting member through the relative position of the first fixing seat 704 and the first base; in the case where the first slider 715 moves on the first guide rail 710, the first slider 715 drives the second slider 709 to move in the opposite direction on the second guide rail 705 through the connecting member.

[0064] The first base of this embodiment can be arranged on the door 2 of the cabinet. 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 door 2 of the cabinet.

[0065] Specifically, during the process of the door 2 of the cabinet rotating and opening towards the outside of the cabinet body 1, the cabinet 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, so as to prevent the door panel 21 from interfering with the obstacles outside. During the process of the door 2 of the cabinet rotating and closing towards one side of the cabinet body 1, the cabinet 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., close to the first hinge 4) through the connecting member, so as to prevent the door panel 21 from interfering with the obstacles after closing.

[0066] Meanwhile, by arranging a first fixing seat 704 at one end of the first base, the first fixing seat 704 has a first limiting groove and a second limiting groove for docking with the first guide rail 710 and the second guide rail 705, to limit and guide the position of the connecting member, so that the sliding of the connecting member is smoother and more stable. The first fixing seat 704 can be movable relative to the first base, so that the first fixing seat 704 can tension or relax the connecting member, thereby adjusting the tightness of the connecting member, so that the connecting member can better pull the second slider 709 under the drive of the first slider 715, so as to realize the sliding of the first slider 715 and the second slider 709 in opposite directions.

[0067] 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 corresponding guide rail under the drive of the connecting member, and the sliding directions are opposite. The first slider 715 is connected to the cabinet body 1 through the traction mechanism, and the second slider 709 is connected to the door panel 21 arranged on the outside of the door 2 of the cabinet. So that when the door 2 of the cabinet rotates, the cabinet 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 door 2 of the cabinet, so that the door panel 21 can avoid the obstacles on both sides during the process of the door 2 of the cabinet rotating to open and close. In addition, by arranging the movable first fixing seat 704 on the first base, the first fixing seat 704 can limit the connecting member and adjust the tightness of the connecting member at the same time, so that the connecting member can better transmit between the first slider 715 and the second slider 709.

[0068] 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 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.

[0069] From the material point of view, the first slider 715, the second slider 709 and other sliders in the present application can be made of materials with high wear resistance, low friction coefficient and good stability, such as metal alloys, engineering plastics or special lubricating materials. The selection of these materials is intended to improve the durability of the slider, reduce wear and noise during sliding, and ensure smooth sliding.

[0070] In terms of structural design, the first slider 715, the second slider 709 and other sliders in the present application can adopt various forms of guide rail contact surfaces, such as plane contact, ball contact or sliding bearing contact. 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.

[0071] In one embodiment of the present application, Figure 1 and Figure 2 As shown, the active sliding door mechanism 7 further includes: a second fixing seat 711. The second fixing seat 711 is connected to the end of the first base away from the first fixing seat 704, and is formed with a second limiting groove, and the two ends of the second limiting groove are butted with the ends of the first guide rail 710 and the second guide rail 705 away from the first fixing seat 704. The connecting member includes a first connecting member 706 and a second connecting member 712. The first connecting member 706 passes through the first limiting groove, and the two ends are respectively connected to one end of the first slider 715 and the second slider 709. The second connecting member 712 passes through the second limiting groove, and the two ends are respectively connected to one end of the first slider 715 and the second slider 709.

[0072] In this embodiment, the first fixing seat 704 and the second fixing seat 711 are respectively arranged at two ends of the first base. The first connecting member 706 passes through the first limiting groove and is respectively connected to one ends of the first sliding block 715 and the second sliding block 709. When the first sliding block 715 slides away from this end of the first base under the drive of the box body 1 and the traction mechanism, the first sliding block 715 drives the second sliding block 709 to slide towards this end of the first base through the first connecting member 706. At the same time, the second connecting member 712 passes through the second limiting groove and is respectively connected to the other ends of the first sliding block 715 and the second sliding block 709. When the first sliding block 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 sliding block 715 drives the second sliding block 709 to slide towards the other end of the first base through the second connecting member 712. Thus, when the first sliding block 715 slides towards both ends of the first base respectively, it can drive the second sliding block 709 to slide in the opposite direction to the first sliding block 715, so that the door panel 21 can slide relative to the box door 2 as the box door 2 rotates when the box door 2 opens and closes, to avoid interference with obstacles and affect the opening and closing of the box door 2. At the same time, the first fixing seat 704 and the second fixing seat 711 can respectively play a role in limiting and guiding the first connecting member 706 and the second connecting member 712.

[0073] In addition, 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 sliding block 715 and the second sliding block 709, when passing through the relative position between the first fixing seat 704 and the first base, the first connecting member 706 correspondingly adjusts the tightness, and the second connecting member 712 also correspondingly adjusts the tightness under the pulling of the first fixing seat 704 on the first connecting member 706.

[0074] 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 717. The first adjusting member 717 passes through the first fixing hole and is slidably arranged in the first waist-shaped hole to adjust the tightness of the first connecting member 706 and the second connecting member 712 by adjusting the position of the first adjusting member 717 in the first waist-shaped hole.

[0075] In this embodiment, by adjusting the position of the first adjusting member 717 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 tension or relax the first connecting member 706, thereby adjusting the tightness of the first connecting member 706.

[0076] 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 adjusting the movement of the first fixing seat 704 relative to the first base through the first waist-shaped hole, the first connecting member 706 correspondingly adjusts the tightness, and the second connecting member 712 also correspondingly adjusts the tightness under the pulling of the first fixing seat 704 on the first connecting member 706.

[0077] It can be understood that a first fixing hole may also be provided on the second fixing seat 711; a first waist-shaped hole extending along the width direction of the first base is provided on the first base; the active sliding door mechanism 7 further includes a first adjusting member 717, the first adjusting member 717 passes through the first fixing hole and is slidably arranged in the first waist-shaped hole to adjust the tightness of the second connecting member 712 by adjusting the position of the first adjusting member 717 in the first waist-shaped hole.

[0078] In this embodiment, by adjusting the position of the first adjusting member 717 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.

[0079] 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 adjusting the movement of the second fixing seat 711 relative to the first base through the first waist-shaped hole, the second connecting member 712 correspondingly adjusts the tightness, and the first connecting member 706 also correspondingly adjusts the tightness under the pulling of the second fixing seat 711 on the second connecting member 712.

[0080] Further, in some embodiments, a second waist-shaped hole extending along the width direction of the first base is provided on the first fixing seat 704. A second fixing hole is provided on the first base. The active sliding door mechanism 7 further includes a second adjusting member 718, the second adjusting member 718 passes through the second waist-shaped hole and the second fixing hole in sequence and is fixed in the external structure to adjust the position of the first fixing seat 704 relative to the external structure by the position of the second adjusting member 718 in the second waist-shaped hole.

[0081] In this embodiment, by providing a second waist-shaped hole on the first fixing base 704 and passing the second adjusting member 718 through the second waist-shaped hole and the second fixing hole in sequence to be fixed in the external structure, so as to fix the first fixing base 704 in the external structure, and thus 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 718 can be finely adjusted in the position along the second waist-shaped hole, so as to adjust the position of the first fixing base 704, and thus be able to cooperate to adjust the position of the first fixing base 704 relative to the external structure.

[0082] It can be understood that the second fixing base 711 can also be provided with a second waist-shaped hole extending along the width direction of the first base; the second adjusting member 718 passes through the second waist-shaped hole and the second fixing hole in sequence to be fixed in the external structure, so as to adjust the position of the second fixing base 711 relative to the external structure through the position of the second adjusting member 718 in the second waist-shaped hole. The functions of the second adjusting member 718, the second waist-shaped hole and the second fixing hole are similar to those in the above embodiment, and will not be elaborated here.

[0083] 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 bent and communicated 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 communicated 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 ends 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 ends of the first slider 715 and the second slider 709.

[0084] In this embodiment, the first limiting sub-groove, the second limiting sub-groove and the third limiting sub-groove are bent and communicated in sequence, so that the first limiting groove can be wound around one end of the first base, so that the first connecting member 706 can 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, the first limiting groove can better limit the first connecting member 706; similarly, the fourth limiting sub-groove, the fifth limiting sub-groove and the sixth limiting sub-groove are bent and communicated in sequence, so that the second limiting groove can be wound around the other end of the first base, so that the second connecting member 712 passes through the second limiting groove and is connected to the other ends of the first slider 715 and the second slider 709, and the second limiting groove can better limit the second connecting member 712. At the same time, the structures of the first limiting groove, the second limiting groove and the first base are made more compact.

[0085] In an embodiment of the present application, as Figure 1 and Figure 2 shown, a rotatable rotating support member 716 is provided in the first limiting groove. A part of the first connecting member 706 is pressed on the rotating support member 716 in the first limiting groove.

[0086] In this embodiment, by providing a rotatable rotating support member 716 in the first limiting groove, a part of the first connecting member 706 is pressed on the rotating support member 716, so as to tension the first connecting member 706 while adjusting the extension and movement direction of the first connecting member 706, so that when the first slider 715 moves along the first guide rail 710, the second slider 709 can be driven to move on the second guide rail 705 through the connecting member, and the movement direction of the second slider 709 is opposite to the movement direction of the first slider 715, so as to drive the door panel 21 to avoid obstacles. At the same time, the rotating support member 716 can reduce the contact between the first connecting member 706 and the groove wall of the first limiting groove, and the rotating support member 716 can rotate, so that the contact between the rotating support member 716 and the first connecting member 706 is rolling friction, which is beneficial to reducing the friction force received by the first connecting member 706, thereby reducing the wear of the first connecting member 706 and making the movement of the first connecting member 706 smoother.

[0087] Optionally, a rotatable rotating support member 716 is provided in the second limiting groove. A part of the second connecting member 712 is pressed on the rotating support member 716 in the second limiting groove.

[0088] In this embodiment, by providing a rotatable rotating support member 716 in the second limiting groove, a part of the second connecting member 712 is pressed on the rotating support member 716, so as to tension the second connecting member 712 while adjusting the extension and movement direction of the second connecting member 712, so that when the first slider 715 moves along the first guide rail 710, the second slider 709 can be driven to move on the second guide rail 705 through the connecting member, and the movement direction of the second slider 709 is opposite to the movement direction of the first slider 715, so as to drive the door panel 21 to avoid obstacles. At the same time, the rotating support member 716 can reduce the contact between the second connecting member 712 and the groove wall of the second limiting groove, and the rotating support member 716 can rotate, so that the contact between the rotating support member 716 and the second connecting member 712 is rolling friction, which is beneficial to reducing the friction force received by the second connecting member 712, thereby reducing the wear of the second connecting member 712 and making the movement of the second connecting member 712 smoother.

[0089] Specifically, in an embodiment of the present application, the rotating support member 716 includes: a rotating shaft 7161 and a roller 7162. The rotating shaft 7161 is rotatably arranged in the first limiting groove or the second limiting groove, the roller 7162 is rotatably arranged on its rotating shaft 7161, a part of the first connecting member 706 is pressed on the roller 7162 in the first limiting groove, and a part of the second connecting member 712 is pressed on the roller 7162 in the second limiting groove.

[0090] In this embodiment, a rotating shaft 7161 is rotatably provided in the first limiting groove and the second limiting groove, and a corresponding roller 7162 is rotatably provided on the rotating shaft 7161, and the roller 7162 can freely rotate on the rotating shaft 7161. At the same time, by pressing a part of the first connecting member 706 and the second connecting member 712 on the roller 7162 of the first limiting groove and the roller 7162 of the second limiting groove respectively, when the first connecting member 706 and the second connecting member 712 slide relative to the roller 7162, the roller 7162 can rotate on the corresponding rotating shaft 7161 with the sliding, so that the friction between the first connecting member 706 and the roller 7162, and the second connecting member 712 and the roller 7162 is rolling friction, thereby reducing the wear between the first connecting member 706 and the roller 7162, and the second connecting member 712 and the roller 7162, and extending the service life.

[0091] In one embodiment of the present application, Figure 1 and Figure 2 As 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 sides of the first base that are away from each other.

[0092] 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.

[0093] 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.

[0094] 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 3As shown by the double-headed arrow in the middle. It should be noted that for the parallel and perpendicular relationships in this application, the installation errors between various components need to be considered, and an error of plus or minus 10° should be understood as the scope protected by the patent.

[0095] Specifically, during the process of the door 2 of the box rotating outward and opening relative to the box body 1 (as Figure 3 shown by the arc arrow in the middle), the first slider 715 slides in the direction close to the first hinge 4 under the drive of the box body 1 and the traction mechanism. The first slider 715 drives the second slider 709 to slide in the direction away from the first hinge 4 through the cooperation of the connecting piece and the rotating support 716, thereby driving the door panel 21 to slide in the direction away from the first hinge 4, and further avoiding interference between the door panel 21 and the obstacles on the outside. Similarly, during the process of the door 2 of the box rotating and closing towards one side of the box body 1, the active sliding door mechanism 7 drives the door panel 21 to slide in the direction close to the first hinge 4, thereby avoiding interference between the door panel 21 and the obstacles after closing.

[0096] According to the door body assembly of the embodiment of the present application, an active sliding door mechanism 7 is provided on the door 2 of the box. The active sliding door mechanism 7 is respectively connected to the door 2 of the box and the door panel 21, so as to drive the door panel 21 to slide in the width direction of the door 2 of the box during the process of the door 2 of the box rotating and opening or closing relative to the box body 1, so that the door panel 21 can avoid obstacles such as side walls and objects during the closing or opening process of the door 2 of the box.

[0097] It can be understood that if the active sliding door mechanism 7 has the beneficial effects of the above embodiment, the door body assembly correspondingly has the beneficial effects of the above embodiment, and its specific implementation manner can refer to the above embodiment, and the present application will not be elaborated here.

[0098] In an embodiment of the present 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 be connected 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.

[0099] In this embodiment, the first rotating shaft fixing seat 713 and the second rotating shaft fixing seat 701 are respectively fixed on the first slider 715 and the box body 1, and are connected by a traction rod 702 between the first rotating shaft fixing seat 713 and the second rotating shaft fixing seat 701, so that the distance between the first slider 715 and the second rotating shaft fixing seat 701 always remains unchanged. When the door 2 rotates relative to the box body 1, the angle between the box body 1 and the door 2 changes, so that the first slider 715 is pulled through the transmission connection of the traction rod 702, the first rotating shaft fixing seat 713 and the second rotating shaft fixing seat 701, so that the first slider 715 slides on the first base, and drives the second slider 709 to slide to realize the movement of the door panel 21 relative to the door 2.

[0100] Specifically, one end of the traction rod 702 is rotatably connected to the first rotating shaft fixing seat 713 through a pin shaft 703, and the other end is rotatably connected to the second rotating shaft fixing seat 701 through another pin shaft 703.

[0101] 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.

[0102] In this embodiment, by providing the driven sliding door mechanism 8 on the door 2, the driven sliding door mechanism 8 has a second base 817, the second base 817 is provided with a third guide rail and a third slider 813 that can slide along the third guide rail, and the third slider 813 is connected to the door panel 21. The third slider 813 can slide along with the door panel 21 when the door panel 21 slides relative to the door 2, playing a role of supporting and assisting the sliding of the door panel 21, so that the door panel 21 slides more smoothly relative to the door 2. 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, reduce the shaking generated during the sliding process of the door panel 21, and make the sliding more stable.

[0103] Optionally, there can be multiple driven sliding door mechanisms 8. Among them, some driven sliding door mechanisms 8 can be coaxially arranged with the active sliding door mechanism 7 on the door 2; another part of the driven sliding door mechanisms 8 are arranged on the door 2 with the active sliding door mechanism 7 being non-coaxial.

[0104] 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 situations where precise control of the movement direction or maintaining the relative position relationship between components is required.

[0105] 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 movement trajectories.

[0106] 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.

[0107] 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.

[0108] 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 cabinet bodies, the door panel 21 can be set flush with the side wall of the groove or the cabinet bodies on both sides, so as to reduce the gap between the refrigeration device and the adjacent wall or cabinet body, making it more beautiful.

[0109] 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 body 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 normally opened or closed.

[0110] 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 usability. Especially in a narrow kitchen environment, this design advantage is more obvious. In addition, the setting of the slider, guide rail and the balls 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.

[0111] 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, and its specific implementation manners can refer to the above embodiments, and the present application will not be elaborated herein.

[0112] It can be understood that there can be multiple storage spaces.

[0113] It is understandable that multiple storage spaces can be arranged arbitrarily, such as arranged vertically or horizontally. Multiple storage spaces can set storage conditions according to storage needs. For example, some storage spaces are set as refrigerating chambers, and another part of the storage spaces are set as freezing chambers.

[0114] As Figure 3 shown, an application scenario based on the above embodiment is as follows: The refrigeration device can be installed in a groove-shaped 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-shaped structure and fits as closely as possible to the opening of the groove-shaped 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.

[0115] 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 the state flush with the cabinet body again.

[0116] 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.

[0117] 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.

[0118] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model, rather than to limit the present utility model. Although the present utility model 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 substitutions of the technical solutions of the present utility model do not depart from the spirit and scope of the technical solutions of the present utility model, and should all be covered within the scope of the claims of the present utility model.
