The first slider is connected to the box body through a traction mechanism, and the second slider is connected to the door panel arranged on the outer side of the box door. So that when the box door rotates, the box body drives the two sliders to slide relatively through the traction mechanism and the connecting member, so as to drive the door panel to slide relative to the box door, so that the door panel can avoid obstacles on both sides during the process of the box door rotating and opening or closing.

[0063] The following will be combined with Figures 1 to 6 to describe the active sliding door mechanism, door body assembly and refrigeration equipment 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 equipment. The refrigeration equipment in the present application is, for example, applied to a refrigerator. However, it should be understood that the refrigeration equipment of the present application can also be applied to a freezer or any other suitable equipment.

[0064] In one embodiment of the present application, as Figure 1 、 Figure 2 and Figure 3As shown in the figure, the active sliding door mechanism 7 is applied to a refrigeration device, which 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 arranged 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 sleeved 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, which is sleeved on the second guide rail 705, and the second slider 709 is used for connecting with the door panel 21; four groups of first balls 7141 and four groups of second balls 7071, the four groups of first balls 7141 are rotatably arranged between the first slider 715 and the first guide rail 710, and the four groups of second balls 7071 are rotatably arranged between the second slider 709 and the second guide rail 705, so that the first slider 715 can be slidably arranged on the first guide rail 710 through the four groups of first balls 7141, and the second slider 709 can be slidably arranged on the second guide rail 705 through the four groups of second balls 7071; a connecting piece, the two ends of which are respectively connected to the first slider 715 and the second slider 709; when 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 piece.

[0065] The first base of this embodiment can be arranged on the box door 2. The connecting piece can be a connecting component such as a traction rope or a transmission belt. The two ends of the connecting piece 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 then drive the door panel 21 to slide relative to the box door 2.

[0066] By reasonably setting the extending direction of the connecting piece, the first slider 715 and the second slider 709 move in opposite directions during movement, so as to drive the door panel 21 to avoid obstacles.

[0067] Specifically, during the process of the box door 2 rotating outward and opening towards the outside of 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 (that is, away from the first hinge 4) through the connecting piece, so as to avoid interference between the door panel 21 and the external obstacles. During the process of the box door 2 rotating and closing towards one side of the box body 1, 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 (that is, close to the first hinge 4) through the connecting piece, so as to avoid interference between the door panel 21 and the obstacles after closing.

[0068] Meanwhile, by respectively arranging four groups of first ball bearings 7141 between the first slider 715 and the first guide rail 710, and between the second slider 709 and the second guide rail 705, the sliding friction between the sliders and the guide rails is converted into rolling friction, making the sliding of the first slider 715 and the second slider 709 smoother, and thus making the sliding of the door panel 21 smoother as well.

[0069] 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. Driven by the connecting member, the first slider 715 and the second slider 709 can slide synchronously along their respective guide rails in opposite directions. 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 when the box door 2 rotates, the box body 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 box door 2, so that the door panel 21 can avoid obstacles on both sides during the rotation and opening / closing of the box door 2. Meanwhile, by arranging four groups of first ball bearings 7141 and second ball bearings 7071 between the sliders and the guide rails, it is beneficial to reduce the friction force between the sliders and the guide rails, making the sliding of the first slider 715 and the second slider 709 smoother, and thus making the sliding of the door panel 21 smoother as well.

[0070] It should be noted that in practical applications, the designs of the first slider 715 and 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.

[0071] From the perspective of materials, the first slider 715 and the second slider 709 and other sliders in the present application can select materials with high wear resistance, low friction coefficient and good stability, such as metal alloys, engineering plastics or special lubricating materials. The selection of these materials aims to improve the durability of the sliders, reduce wear and noise during the sliding process, and ensure the smoothness of the sliding.

[0072] In terms of structural design, the first slider 715 and 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, 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 selecting, factors such as usage conditions, cost-effectiveness and maintenance convenience should be comprehensively considered.

[0073] In an embodiment of the present application, a clamping groove 708 is provided on the second slider 709 for plugging with the plug-in member on the door panel 21.

[0074] 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.

[0075] In this embodiment, by respectively 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, 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, the first slider 715 is tractioned 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 box door 2.

[0076] 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.

[0077] In an embodiment of the present application, as Figure 3 shown, four rows of first rolling gaps are formed between the first slider 715 and the first guide rail 710, and four rows of second rolling gaps are formed between the second slider 709 and the second guide rail 705; wherein, four groups of first ball bearings 7141 are respectively rotatably arranged in the first rolling gaps, and four groups of second ball bearings 7071 are respectively rotatably arranged in the second rolling gaps.

[0078] In this embodiment, by respectively forming a first rolling gap between the first slider 715 and the first guide rail 710 and a second rolling gap between the second slider 709 and the second guide rail 705, direct contact between the first slider 715 and the first guide rail 710 and between the second slider 709 and the second guide rail 705 can be avoided. And first rolling balls 7141 and second rolling balls 7071 that can roll are respectively arranged in the first rolling gap and the second rolling gap, so that the first slider 715 can slide along the first guide rail 710 through the rolling of the first rolling balls 7141, and the second slider 709 can slide along the second guide rail 705 through the rolling of the second rolling balls 7071. The friction is small and the sliding is smoother.

[0079] Further, as Figure 3 shown, the first guide rail 710 is provided with four first concave surfaces arranged in sequence along its circumferential direction. A first groove is formed on the first slider 715. Four rows of first rolling gaps are formed between the side walls of the first groove and the four first concave surfaces. The second guide rail 705 is provided with four second concave surfaces arranged in sequence along its circumferential direction. A second groove is formed on the second slider 709. Four rows of second rolling gaps are formed between the side walls of the second groove and the four second concave surfaces.

[0080] In this embodiment, by providing a first groove on the first slider 715 and a first concave surface on the first guide rail 710, the first concave surface and the first groove oppositely form a first rolling gap. The first concave surface and the first groove respectively abut against both sides of the first rolling ball 7141. The first rolling ball 7141 can roll in the first rolling gap to realize the relative sliding between the first slider 715 and the first guide rail 710. At the same time, the first concave surface can limit the first rolling ball 7141 in the circumferential direction of the first guide rail 710 to avoid circumferential offset of the first rolling ball 7141 on the first guide rail 710, making the sliding of the first slider 715 more stable and smoother. Similarly, the second groove on the second slider 709 and the second concave surface of the second guide rail 705 oppositely form a second rolling gap. The second concave surface and the second groove respectively abut against both sides of the second rolling ball 7071, so that the second rolling ball 7071 does not have circumferential offset when rolling to realize the relative sliding between the second slider 709 and the second guide rail 705, making the sliding of the second slider 709 more stable and smoother.

[0081] Specifically, in an embodiment of the present application, as Figure 3As shown, a row of first rolling gaps are formed between the side wall at one end of the first groove and one of the first concave surfaces, a row of first rolling gaps are formed between the side wall at the other end of the first groove and the other first concave surface, and two rows of first rolling gaps are formed between the side wall in the middle of the first groove and the remaining first concave surfaces. A row of second rolling gaps are formed between the side wall at one end of the second groove and one of the second concave surfaces, a row of second rolling gaps are formed between the side wall at the other end of the second groove and the other second concave surface, and two rows of second rolling gaps are formed between the side wall in the middle of the second groove and the remaining second concave surfaces.

[0082] In this embodiment, by forming two rows of first rolling gaps between the side walls at both ends of the first groove and two first concave surfaces respectively, and forming two rows of first rolling gaps between the side wall in the middle of the first groove and the other two second concave surfaces, the four rows of first rolling gaps are respectively used to arrange four groups of first balls 7141, and the forces on the four groups of first balls 7141 are more evenly distributed, which is beneficial to improving the stability and service life of the whole structure. Similarly, by forming four rows of second rolling gaps between the three side walls of the second groove and three second concave surfaces respectively, the four rows of second rolling gaps are respectively used to arrange four groups of second balls 7071, and the forces on the four groups of second balls 7071 are more evenly distributed, which is beneficial to improving the stability and service life of the whole structure.

[0083] Specifically, in an embodiment of the present application, the projections of the axes of the four rows of first rolling gaps on the cross-section of the first guide rail 710 are arranged in a square, and are respectively located at the four vertices of the square, and the central axis of the first guide rail 710 passes through the center of the square.

[0084] Optionally, the first concave surface is an arc surface that fits the first ball 7141, and an arc surface that fits the first ball 7141 is also formed at the position corresponding to the first concave surface on the side wall of the first groove, so that the first concave surface and the first groove can better fit the first ball 7141, with a larger force-bearing area and more stable and reliable rolling; similarly, the second concave surface is an arc surface that fits the second ball 7071, and an arc surface that fits the second ball 7071 is also formed at the position corresponding to the second concave surface on the side wall of the second groove, so that the second concave surface and the second groove can better fit the second ball 7071, with a larger force-bearing area and more stable and reliable rolling.

[0085] In an embodiment of the present application, as Figure 3As shown, the active sliding door mechanism 7 further includes: a first support frame 714 and a second support frame 707. The first support frame 714 is disposed between the first slider 715 and the first guide rail 710. The first support frame 714 is provided with first limiting notches at positions corresponding to the four rows of first rolling gaps, and four groups of first balls 7141 are disposed in the first limiting notches. The second support frame 707 is disposed between the second slider 709 and the second guide rail 705. The second support frame 707 is provided with second limiting notches at positions corresponding to the four rows of second rolling gaps, and four groups of second balls 7071 are disposed in the second limiting notches.

[0086] In this embodiment, by disposing the first support frame 714 between the first slider 715 and the first guide rail 710, the first support frame 714 is formed with first limiting notches to dispose the first balls 7141, so as to limit the first balls 7141 and prevent the first balls 7141 from rolling and shifting in the first rolling gaps, making the sliding of the first slider 715 more stable and reliable; similarly, by disposing the second support frame 707 between the second slider 709 and the second guide rail 705 to limit the second balls 7071, the sliding of the second slider 709 is made more stable and reliable.

[0087] Specifically, in an embodiment of the present application, the first limiting notch is a first arc-shaped notch matching the shape of the first ball 7141, and the second limiting notch is a second arc-shaped notch matching the shape of the second ball 7071.

[0088] In this embodiment, by setting the first limiting notch as the first arc-shaped notch matching the shape of the first ball 7141, the first arc-shaped notch can better fit the first ball 7141, and the limiting effect on the first ball 7141 is better. When the first arc-shaped notch contacts the first ball 7141, the stress area is larger, the force is more dispersed, the wear between the first arc-shaped notch and the first ball 7141 can be reduced, and the service life can be extended. Similarly, by setting the second limiting notch as the second arc-shaped notch, it can also better fit the second ball 7071, the limiting effect on the second ball 7071 is better. When the first arc-shaped notch contacts the second ball 7071, the stress area is larger, the force is more dispersed, the wear between the first arc-shaped notch and the second ball 7071 can be reduced, and the service life can be extended.

[0089] In an embodiment of the present application, as Figure 1 and Figure 2 shown, 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, 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 bypasses the other end of the first base, and the two ends are respectively connected to the other end of the first slider 715 and the second slider 709.

[0090] 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, 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; meanwhile, 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, 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, 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.

[0091] 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, and a first limiting groove is formed. Both ends of the first limiting groove are butted against one end of the first guide rail 710 and the second guide rail 705, and a part of the first connecting member 706 is slidably arranged in the first limiting groove; the second fixed seat 711, which is connected to the other end of the first base, forms 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, and a part of the second connecting member 712 is slidably arranged in the second limiting groove.

[0092] In this embodiment, by respectively arranging the first fixed seat 704 and the second fixed seat 711 at both ends of the first base, the first fixed seat 704 and the second fixed seat 711 respectively form a first limiting groove and a second limiting groove that are butted against the first guide rail 710 and the second guide rail 705, to respectively limit and guide the positions of the first connecting member 706 and the second connecting member 712, making the sliding of the first connecting member 706 and the second connecting member 712 smoother and more stable.

[0093] Specifically, the first fixed 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 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.

[0094] 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 tension or relax the first connecting member 706, thereby adjusting the tightness of the first connecting member 706.

[0095] 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 first fixing seat 704 is adjusted to move relative to the first base 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.

[0096] It can be understood that the first fixing hole can 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, and the first adjusting member 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 in the first waist-shaped hole.

[0097] 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.

[0098] 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.

[0099] Furthermore, 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, 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 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.

[0100] In this embodiment, the first fixing seat 704 is fixed to the external structure by providing a second waist-shaped hole on the first fixing seat 704, and the second adjusting member is sequentially passed through the second waist-shaped hole and the second fixing hole to be fixed to the external structure, so as to fix the first fixing seat 704 to the external structure, so as to fix the active sliding door mechanism 7 to the external structure (such as the box door 2). At the same time, the second adjusting member can be fine-tuned in the position along the second waist-shaped hole to adjust the position of the first fixing seat 704, so as to cooperate with adjusting the position of the first fixing seat 704 relative to the external structure.

[0101] It is understandable that the second fixing seat 711 may 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 that the position of the second fixing seat 711 relative to the external structure is adjusted 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 embodiment and are not described in detail here.

[0102] In another embodiment of the present application, Figure 4 and Figure 5 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.

[0103] 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 4 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.

[0104] Specifically, during the process of the door 2 rotating toward the outside of the box body 1 to open (eg Figure 4As shown by the middle arc arrow, under the drive of the box body 1 and the traction mechanism, the first slider 715 slides towards the direction close to the first hinge 4. The first slider 715 drives the second slider 709 to slide away from the first hinge 4 through a connecting member, thereby driving the door panel 21 to slide away from the first hinge 4, thus avoiding interference between the door panel 21 and the obstacles on the outside. Similarly, during the process of the box door 2 rotating and closing towards the box body 1, the active sliding door mechanism 7 drives the door panel 21 to slide towards the direction close to the first hinge 4, thereby avoiding interference between the door panel 21 and the obstacles after closing. At the same time, when the slider and the guide rail slide relative to each other, the four groups of first balls 7141 and the four groups of second balls 7071 between the slider and the guide rail can convert sliding friction into rolling friction, reduce the friction force received by the first slider 715 and the second slider 709, and make the sliding smoother.

[0105] For the door body assembly according to the embodiment of the present application, an active sliding door mechanism 7 is provided on the box door 2. The active sliding door mechanism 7 is respectively connected to the box door 2 and the door panel 21, so as to drive the door panel 21 to slide in the width direction of the box door 2 during the process of the box door 2 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 box door 2. At the same time, the four groups of first balls 7141 and the four groups of second balls 7071 of the active sliding door mechanism 7 can reduce the friction force received by the slider, and make the sliding of the door panel 21 smoother.

[0106] It can be understood that if the active sliding door mechanism 7 has the beneficial effects of the above embodiment, then the door body assembly correspondingly has the beneficial effects of the above embodiment. The specific implementation manner can refer to the above embodiment, and the present application will not be elaborated herein.

[0107] In an embodiment of the present application, as Figure 6 shown, the door body assembly further includes: a driven sliding door mechanism 8. 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.

[0108] In this embodiment, by providing the driven sliding door mechanism 8 on the box 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. 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 box door 2, playing a supporting and assisting role in the sliding of the door panel 21, and making the sliding of the door panel 21 relative to the box 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, reduce the shaking generated during the sliding of the door panel 21, and make the sliding more stable.

[0109] Optionally, there may be multiple driven sliding door mechanisms 8. Among them, some of the driven sliding door mechanisms 8 may be coaxially arranged with the active sliding door mechanism 7 on the cabinet door 2; another part of the driven sliding door mechanisms 8 is arranged non-coaxially with the active sliding door mechanism 7 on the cabinet door 2.

[0110] In an embodiment of another aspect of the present application, as Figure 4 and Figure 5 shown, a refrigeration device is provided, including: a cabinet 1 and a door body assembly provided in any of the above embodiments. Among them, the cabinet 1 forms a storage space, and the cabinet door 2 is rotatably connected to the cabinet 1 and is adapted to open or close the storage space.

[0111] In this embodiment, the door body assembly includes: a cabinet door 2, a door panel 21, and an active sliding door mechanism 7. The active sliding door mechanism 7 is arranged on the cabinet door 2 and is configured to drive the door panel 21 to move relative to the width direction of the cabinet door 2 during the opening or closing process of the cabinet door 2.

[0112] By providing the door panel 21 on the cabinet 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.

[0113] At the same time, 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 of the cabinet door 2 to move as far as possible away from obstacles such as the wall or cabinet on the side of the cabinet 1 of the door, so as to avoid these obstacles blocking the door panel 21 and affecting the rotation of the cabinet door 2, resulting in the cabinet door 2 being unable to be normally opened or closed.

[0114] The combination of the cabinet 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.

[0115] It can be understood that if the door body assembly has the beneficial effects of the above embodiments, then 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.

[0116] It can be understood that there may be multiple storage spaces.

[0117] It is understandable that multiple storage spaces can be arranged arbitrarily, such as arranged vertically, horizontally, etc. The multiple storage spaces can set storage conditions according to storage needs. For example, some storage spaces are set as refrigerating chambers, and some other storage spaces are set as freezing chambers.

[0118] As Figure 4 shown, based on an application scenario of the above embodiment, the following is the case: The refrigeration device can be installed in a groove-shaped structure in the middle of a cabinet body. A door panel 21 is arranged on the outer side of the door 2 of the box body 1 of the refrigeration device, and 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 is as close 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.

[0119] When the door 2 rotates outward to open, the active sliding door mechanism 7 drives the door panel 21 to slide in a direction away from the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall near 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 in a direction close to the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall away from the first hinge 4, resulting in the door 2 being unable to be completely closed, which affects 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.

[0120] In an embodiment of the present application, as Figure 5 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.

[0121] In this embodiment, by setting the first storage space and the second storage space on the box body 1, the items to be stored are stored separately according to requirements. The first storage space and the second storage space are respectively provided with the first door body assembly and the 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 be opened and closed, the corresponding door panels 21 can slide relative to the door 2 to avoid obstacles.

[0122] 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 substitutions 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.
