[0002] With the increasing demand for the integration of household appliances and home furnishings, the embedded design of household appliances has become a trend.

[0003] However, in order to pursue a better home integration effect, sometimes it is necessary to fixedly connect a door panel to the surface of the cabinet door, and at the same time, the gap between the embedded appliance and the side wall of the cabinet is required to be higher to further improve the home integration effect. This results in that after the appliance is embedded in the cabinet, if the existing hinge technology is adopted, the door body assembly with the door panel will interfere with the side wall of the installation space in the cabinet during the process of opening and closing the door, thus causing the door body assembly of the appliance to be unable to be opened or closed normally.

[0074] The following will describe the door body assembly and the refrigeration device of the present application in conjunction with Figures 1 to 23 Describe the door body assembly and the refrigeration device of the present application. The door body assembly in the present application can be applied to household appliances, such as a refrigerator. However, it should be understood that the 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 to freezers or any other suitable devices.

[0075] In one embodiment of the present application, as Figure 1 and Figure 2 shown, the door body assembly is applied to a refrigeration device. The refrigeration device includes a box body 1. The door body assembly includes: a box door 2, rotatably connected to the box body 1 and adapted to open or close the storage space of the box body 1. A door panel 21 is slidably disposed outside the box door 2. A traction mechanism, a main sliding door mechanism 7, and a first driven sliding door mechanism 9. The first driven sliding door mechanism 9 is disposed on the box door 2 coaxially different from the main sliding door mechanism 7. The main sliding door mechanism 7 is connected to the box body 1 through the traction mechanism and is slidably connected to the door panel 21. The main sliding door mechanism 7 is configured to drive the main sliding door mechanism 7 by the traction mechanism during the opening or closing process of the box door 2, so that the main sliding door mechanism 7 drives the door panel 21 to move relative to the width direction of the box door 2. The first driven sliding door mechanism 9 is configured to cooperate to guide the door panel 21 to move relative to the box door 2.

[0076] Among them, both the main sliding door mechanism 7 and the second driven sliding door mechanism 8 can include relatively sliding movable parts such as sliders and slide rails. The two relatively sliding parts of the main sliding door mechanism 7 are respectively connected to the box door 2 and the door panel 21 through suitable connection methods (such as bolt connection, welding, etc.). At the same time, the main sliding door mechanism 7 is connected to the box body 1 through the traction mechanism. In this way, when the box door 2 rotates to open and close, the box body 1 rotates relative to the box door 2, so as to drive the main sliding door mechanism 7 through the traction mechanism, so that the main sliding door mechanism 7 can drive the door panel 21 to move relative to the width direction of the box door 2 during the rotation of the box door 2 (such as Figure 1as shown by the double-headed arrow in the middle), as far away as possible from obstacles such as walls and objects on the side 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.

[0077] Specifically, during the process of the box door 2 rotating and opening towards the outside of the box body 1 (as Figure 1 shown by the arc arrow in the middle), the active sliding door mechanism 7 drives the door panel 21 to slide in a direction away from the first hinge 4, thereby avoiding interference between the door panel 21 and the outside obstacles. During the process of the box door 2 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 a direction close to the first hinge 4, thereby avoiding interference between the door panel 21 and the obstacles after closing.

[0078] At the same time, by arranging the first driven sliding door mechanism 9 and the active sliding door mechanism 7 on different axes, it plays a role in supporting and assisting the sliding of the door panel 21, and avoids the deflection of the door panel 21 around the sliding direction during sliding. The second driven sliding door mechanism 8 and the first driven sliding door mechanism 9 can cooperate with the active sliding door mechanism 7 to make the sliding of the door panel 21 more stable and smooth. The first driven sliding door mechanism 9 and the active sliding door mechanism 7 are arranged on different axes, 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 arrangement is used in situations where it is necessary to disperse forces, increase stability or achieve complex movement trajectories.

[0079] According to the door body assembly of the embodiment of the present application, the box door 2 is rotatably connected to the box body 1, the door panel 21 is slidably arranged on the outside of the box door 2, and the active sliding door mechanism 7 is arranged on the box door 2. The active sliding door mechanism 7 is respectively connected to the box door 2 and the door panel 21, and is connected to the box body 1 through the traction mechanism. During the process of the box door 2 rotating and opening or closing relative to the box body 1, the box body 1 can drive the active sliding door mechanism 7 through the traction mechanism, so that the active sliding door mechanism 7 drives the door panel 21 to slide in the width direction of the box door 2, so that the door panel 21 can avoid side walls, objects and other obstacles during the closing or opening process of the box door 2, so as to meet the usage requirements of different scenarios of users. At the same time, by setting the first driven sliding door mechanism 9 to support and assist the sliding of the door panel 21, the sliding of the door panel 21 is made more stable and smooth, and the use effect is better.

[0080] Optionally, in an embodiment of the present application, as Figure 1 and Figure 2 shown, both the first driven sliding door mechanism 9 and the active sliding door mechanism 7 are arranged along the width direction of the box door 2. The active sliding door mechanism 7 is arranged at the top of the box door 2, and the first driven sliding door mechanism 9 is arranged at the bottom of the box door 2.

[0081] In this embodiment, the active sliding door mechanism 7 and the first driven sliding door mechanism 9 are both arranged along the width direction of the door panel 2, so as to drive or guide the door plate 21 to slide along the width direction of the door panel 2, enabling the door plate 21 to slide during the rotation of the door panel 2 to avoid obstacles on both sides. At the same time, by arranging the active sliding door mechanism 7 at the top of the door panel 2 and the first driven sliding door mechanism 9 at the bottom of the door panel 2, the active sliding door mechanism 7, the second driven sliding door mechanism 8 and the first driven sliding door mechanism 9 can respectively limit the door plate 21 at the top and bottom of the door panel 2, supporting the door plate 21 while preventing the door plate 21 from shaking. The structure is simple, convenient and practical.

[0082] Optionally, in another embodiment of the present application, the active sliding door mechanism 7 is arranged at the bottom of the door panel 2, and the first driven sliding door mechanism 9 is arranged at the top of the door panel 2.

[0083] Similar to the foregoing embodiment, by arranging the active sliding door mechanism 7 at the bottom of the door panel 2 and the first driven sliding door mechanism 9 at the top of the door panel 2, it is also possible to limit the door plate 21 at positions near the upper and lower ends of the door panel 2, supporting the door plate 21 while preventing the door plate 21 from swinging and shaking. The structure is simple, convenient and practical.

[0084] Optionally, in an embodiment of the present application, as Figure 1 and Figure 2 shown, the door body assembly further includes: a second driven sliding door mechanism 8, arranged along the width direction of the door panel 2, coaxially arranged with the active sliding door mechanism 7 on the door panel 2; the first driven sliding door mechanism 9 and the second driven sliding door mechanism 8 are configured to cooperate to guide the door plate 21 to move relative to the door panel 2 during the opening or closing of the door panel 2.

[0085] In this embodiment, the second driven sliding door mechanism 8 is coaxially arranged with the active sliding door mechanism 7, which plays a role in supporting and assisting the sliding of the door plate 21 and prevents the door plate 21 from swinging during sliding. The second driven sliding door mechanism 8 and the first driven sliding door mechanism 9 can cooperate with the active sliding door mechanism 7 to make the sliding of the door plate 21 more stable and smooth.

[0086] Optionally, in an embodiment of the present application, as Figure 1 and Figure 2 shown, the active sliding door mechanism 7 and the second driven sliding door mechanism 8 are arranged at the top of the door panel 2, and the first driven sliding door mechanism 9 is arranged at the bottom of the door panel 2.

[0087] In this embodiment, the active sliding door mechanism 7, the second driven sliding door mechanism 8 and the first driven sliding door mechanism 9 are all arranged along the width direction of the door 2, so as to drive or guide the door panel 21 to slide along the width direction of the door 2, so that the door panel 21 can slide during the rotation of the door 2 to avoid obstacles on both sides. At the same time, by arranging the active sliding door mechanism 7 and the second driven sliding door mechanism 8 at the top of the door 2 and the first driven sliding door mechanism 9 at the bottom of the door 2, the active sliding door mechanism 7, the second driven sliding door mechanism 8 and the first driven sliding door mechanism 9 can limit the door panel 21 at the top and bottom of the door 2 respectively, and the door panel 21 swings and shakes while supporting the door panel 21, which has a simple structure and is convenient and practical.

[0088] Optionally, in another embodiment of the present application, the active sliding door mechanism 7 and the second driven sliding door mechanism 8 are arranged at the bottom of the box door 2, and the first driven sliding door mechanism 9 is arranged at the top of the box door 2.

[0089] Similar to the aforementioned embodiment, by arranging the active sliding door mechanism 7 and the second driven sliding door mechanism 8 at the bottom of the box door 2 and the first driven sliding door mechanism 9 at the top of the box door 2, the door panel 21 can also be limited at positions close to the upper and lower ends of the box door 2, and the door panel 21 can be swung and shaken while supporting the door panel 21. The structure is simple, convenient and practical.

[0090] In the embodiments of the present application, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the active sliding door mechanism 7 includes: a first base 717, a first slider 714 and a second slider 713. A first guide rail is formed on one side of the first base 717, and a second guide rail is formed on the other side. The first slider 714 is transmission-connected to the box body 1 through a traction mechanism, and is slidably disposed on the first guide rail. The second slider 713 is connected to the door panel 21 and is slidably disposed on the second guide rail. The two ends of the connecting member 706 are respectively connected to the first slider 714 and the second slider 713. In the process of opening or closing the box door 2, the box body 1 drives the first slider 714 to move on the first guide rail through the traction mechanism, and the first slider 714 drives the second slider 713 to move in the opposite direction on the second guide rail through the connecting member 706, so as to drive the door panel 21 to move relative to the box door 2.

[0091] It should be noted that, in practical applications, the designs of the first slider 714, the second slider 713 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.

[0092] From a material perspective, the first slider 714, the second slider 713, and other sliders in this application can be made of materials with high wear resistance, low friction coefficients, 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.

[0093] In terms of structural design, the first slider 714, the second slider 713, and other sliders in this application can adopt various forms of guide rail contact surfaces, such as planar contact, ball contact, or sliding bearing contact, 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 planar 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.

[0094] The connecting member 706 can be a connecting component such as a towing rope or a transmission belt. The two ends of the connecting member 706 are respectively connected to the first slider 714 and the second slider 713, enabling the first slider 714 to drive the second slider 713 to move synchronously, and then driving the door panel 21 to slide relative to the cabinet door 2.

[0095] By reasonably setting the extension direction of the connecting member 706, the first slider 714 and the second slider 713 move in opposite directions during movement, so as to drive the door panel 21 to avoid obstacles.

[0096] Specifically, during the process of the cabinet door 2 rotating outward to open relative to the cabinet body 1, the cabinet body 1 drives the first slider 714 to slide in the direction close to the first hinge 4 through the traction mechanism. At the same time, the first slider 714 drives the second slider 713 to slide in the opposite direction (i.e., away from the first hinge 4) through the connecting member 706, thus preventing the door panel 21 from interfering with the external obstacles. During the process of the cabinet door 2 rotating to close towards one side of the cabinet body 1, the cabinet body 1 drives the first slider 714 to slide in the direction away from the first hinge 4 through the traction mechanism. At the same time, the first slider 714 drives the second slider 713 to slide in the opposite direction (i.e., close to the first hinge 4) through the connecting member 706, thus preventing the door panel 21 from interfering with the obstacles after closing.

[0097] In an embodiment of this application, as Figures 4 to 6 shown, the door body assembly further includes a traction mechanism, and the traction mechanism includes a traction rod 709, a first rotating shaft fixing seat 707, and a second rotating shaft fixing seat 710. The first rotating shaft fixing seat 707 is connected to the first slider 714, the second rotating shaft fixing seat 710 is used to be connected to the cabinet body 1, one end of the traction rod 709 is rotatably connected to the first rotating shaft fixing seat 707, and the other end of the traction rod 709 is rotatably connected to the second rotating shaft fixing seat 710.

[0098] In this embodiment, the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710 are respectively fixed on the first slider 714 and the box body 1, and are connected by a traction rod 709 between the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710, so that the distance between the first slider 714 and the second rotating shaft fixing seat 710 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, so that the first slider 714 is pulled by the transmission connection of the traction rod 709, the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710, the first slider 714 slides on the first base 717, and drives the second slider 713 to slide to realize the movement of the door panel 21 relative to the box door 2.

[0099] Specifically, one end of the traction rod 709 and the first rotating shaft fixing seat 707 are rotatably connected through a pin shaft 708 and a third bearing 715, and the other end and the second rotating shaft fixing seat 710 are rotatably connected through another pin shaft 708 and another third bearing 715.

[0100] In an embodiment of the present application, as Figure 3 、 Figure 4 and Figure 5 shown, the connecting member 706 includes: a first connecting member and a second connecting member. The first connecting member bypasses one end of the first base 717, and both ends are respectively connected with one end of the first slider 714 and the second slider 713; the second connecting member bypasses the other end of the first base 717, and both ends are respectively connected with the other end of the first slider 714 and the second slider 713.

[0101] In this embodiment, by connecting the first connecting member to the first slider 714 and the second slider 713 respectively by bypassing one end of the first base 717, when the first slider 714 slides in the direction away from this end of the first base 717 under the drive of the box body 1, the first slider 714 drives the second slider 713 to slide in the direction close to this end of the first base 717 through the first connecting member; at the same time, by connecting the second connecting member to the first slider 714 and the second slider 713 respectively by bypassing the other end of the first base 717, when the first slider 714 slides in the direction away from the other end of the first base 717 under the drive of the box body 1, the first slider 714 drives the second slider 713 to slide in the direction close to the other end of the first base 717 through the second connecting member, so that when the first slider 714 slides to both ends of the first base 717 respectively, it can drive the second slider 713 to slide in the opposite direction to the first slider 714, and further enable the door panel 21 to slide relative to the box door 2 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.

[0102] Specifically, both the second slider 713 and the first slider 714 are provided with connection heads 711 for fixing the connecting member 706.

[0103] In one embodiment of the present application, as Figure 3 , Figure 4 and Figure 5 shown, the active sliding door mechanism 7 further includes: a first fixed seat 701 and a second fixed seat 702. The first fixed seat 701 is connected to one end of the first base 717 and is formed with a first limiting groove. The two ends of the first limiting groove are docked with one ends of the first guide rail and the second guide rail, and a part of the first connecting member is slidably disposed in the first limiting groove; the second fixed seat 702 is connected to the other end of the first base 717 and is formed with a second limiting groove. The two ends of the second limiting groove are docked with the other ends of the first guide rail and the second guide rail, and a part of the second connecting member is slidably disposed in the second limiting groove.

[0104] In this embodiment, by providing the first fixed seat 701 and the second fixed seat 702 at both ends of the first base 717 respectively, the first fixed seat 701 and the second fixed seat 702 are respectively formed with a first limiting groove and a second limiting groove that are docked with the first guide rail and the second guide rail, so as to limit and guide the positions of the first connecting member and the second connecting member respectively, making the sliding of the first connecting member and the second connecting member smoother.

[0105] Specifically, in one embodiment of the present application, the first fixed seat 701 is provided with a first fixing hole, and the first base 717 is provided with a first waist-shaped hole extending along the width direction of the first base 717; the active sliding door mechanism 7 further includes a first adjusting member 704. The first adjusting member 704 passes through the first fixing hole and is slidably disposed in the first waist-shaped hole, so as to adjust the tightness of the first connecting member and the second connecting member by adjusting the position of the first adjusting member 704 in the first waist-shaped hole.

[0106] In this embodiment, by adjusting the position of the first adjusting member 704 in the first waist-shaped hole, the position of the first fixed seat 701 can be adjusted along the width direction of the first base 717, so that the first fixed seat 701 can tension or relax the first connecting member, thereby adjusting the tightness degree of the first connecting member.

[0107] Since the first connecting member and the second connecting member are respectively located on the first fixed seat 701 and the second fixed seat 702 on both sides of the first base 717, and the first connecting member and the second connecting member are connected to both ends of the first slider 714 and the second slider 713, when adjusting the movement of the first fixed seat 701 relative to the first base 717 through the first waist-shaped hole, the tightness degree of the first connecting member is correspondingly adjusted, and the second connecting member is also correspondingly adjusted in tightness degree under the pulling of the first fixed seat 701 on the first connecting member.

[0108] It is understandable that a first fixing hole may also be provided on the second fixing seat 702; a first waist-shaped hole extending along the width direction of the first base 717 is provided on the first base 717; the active sliding door mechanism 7 further includes a first adjusting member 704, the first adjusting member 704 passes through the first fixing hole and is slidably disposed in the first waist-shaped hole, so as to adjust the tightness of the first connecting member and the second connecting member by adjusting the position of the first adjusting member 704 in the first waist-shaped hole.

[0109] In this embodiment, by adjusting the position of the first adjusting member 704 in the first waist-shaped hole, the position of the second fixing seat 702 can be adjusted along the width direction of the first base 717, so that the second fixing seat 702 can tighten or loosen the second connecting member, thereby adjusting the tightness of the second connecting member.

[0110] Since the first connecting member and the second connecting member are respectively located on the first fixing seat 701 and the second fixing seat 702 on both sides of the first base 717, and the first connecting member and the second connecting member are connected to the two ends of the first slider 714 and the second slider 713, when the second fixing seat 702 is adjusted to move relative to the first base 717 through the first waist-shaped hole, the tightness of the second connecting member is correspondingly adjusted, and the first connecting member is also correspondingly adjusted in tightness under the pulling of the second fixing seat 702 on the second connecting member.

[0111] Further, in some embodiments, a second waist-shaped hole extending along the width direction of the first base 717 is provided on the first fixing seat 701. A second fixing hole is provided on the first base 717. The active sliding door mechanism 7 further includes a second adjusting member 703, the second adjusting member 703 sequentially passes through the second waist-shaped hole and the second fixing hole and is fixed in the external structure, so as to adjust the position of the first fixing seat 701 relative to the external structure by the position of the second adjusting member 703 in the second waist-shaped hole.

[0112] It is understandable that a second waist-shaped hole extending along the width direction of the first base 717 may also be provided on the second fixing seat 702; the second adjusting member 703 sequentially passes through the second waist-shaped hole and the second fixing hole and is fixed in the external structure, so as to adjust the position of the second fixing seat 702 relative to the external structure by the position of the second adjusting member 703 in the second waist-shaped hole. The functions of the second adjusting member 703, the second waist-shaped hole and the second fixing hole are similar to those in the above embodiments, and will not be elaborated here.

[0113] Further, in some embodiments, a rotatable support bearing is provided in the first limiting groove; a part of the first connecting member abuts against the support bearing in the first limiting groove. In this embodiment, by abutting a part of the first connecting member against the support bearing, the movement and extension direction of the first connecting member can be adjusted, which is convenient for bypassing the end of the first base 717 and connecting the first connecting member to the first slider 714 and the second slider 713.

[0114] It is understandable that a rotatable support bearing may also be provided in the second limiting groove; a part of the second connecting member abuts against the support bearing in the second limiting groove so as to adjust the extending direction of the second connecting member, facilitating the second connecting member to bypass the end of the first base 717 and be connected to the first slider 714 and the second slider 713.

[0115] Specifically, in some embodiments, the support bearing includes a first bearing 705 and a second bearing 716. The first bearing 705 and the second bearing 716 are respectively located at one end on the same side of the first guide rail and the second guide rail, and are respectively located on both sides of the first base 717.

[0116] In an embodiment of the present application, as Figure 2 、 Figure 6 and Figure 7 shown, the second 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. The third slider 813 is slidably disposed on the third guide rail, and the third slider 813 is connected to the door panel 21.

[0117] In this embodiment, the second driven sliding door mechanism 8 is coaxially arranged with the active sliding door mechanism 7. The third slider 813 can slide coaxially on the third guide rail and with the active sliding door mechanism 7, better assisting the door panel 21 to slide relative to the box door 2 under the drive of the active sliding door mechanism 7. At the same time, the third slider 813 can cooperate with the active sliding door mechanism 7 to limit the movement direction of the door panel 21, preventing the door panel 21 from swinging during the movement.

[0118] In an embodiment of the present application, as Figure 6 and Figure 7 shown, the second driven sliding door mechanism 8 can be arranged in a similar structure to the active sliding door mechanism 7, and the second driven sliding door mechanisms 8 can be swapped with each other when needed.

[0119] Furthermore, the second driven sliding door mechanism 8 further includes a third fixing seat 801 and a fourth fixing seat 802. The third fixing seat 801 and the fourth fixing seat 802 are also provided with limiting grooves similar to those of the first fixing seat 701 and the second fixing seat 702.

[0120] Specifically, the third fixing seat 801 is provided with a third fixing hole, and the second base 817 is provided with a third waist-shaped hole extending along the width direction of the second base 817; a third adjusting member 804 passes through the third fixing hole and is slidably disposed in the third waist-shaped hole to adjust the position of the third adjusting member 804 in the third waist-shaped hole.

[0121] It is understandable that the fourth fixing seat 802 may also be provided with a third fixing hole; the second base 817 is provided with a third waist-shaped hole extending along the width direction of the second base 817; the third adjusting member 804 passes through the third fixing hole and is slidably arranged in the third waist-shaped hole, so as to adjust the position of the third adjusting member 804 in the third waist-shaped hole.

[0122] Further, the third fixing seat 801 is provided with a fourth waist-shaped hole extending in the width direction of the second base 817. The second base 817 is provided with a fourth fixing hole. The fourth adjusting member 803 passes through the fourth waist-shaped hole and the fourth fixing hole in sequence and is fixed in the external structure, so that the position of the third fixing seat 801 relative to the external structure is adjusted by the position of the fourth adjusting member 803 in the fourth waist-shaped hole.

[0123] It is understandable that the fourth fixed seat 802 may also be provided with a fourth waist-shaped hole extending along the width direction of the third base 902; the fourth adjustment member 803 passes through the fourth waist-shaped hole and the fourth fixed hole in sequence and is fixed in the external structure, so as to adjust the position of the fourth fixed seat 802 relative to the external structure through the position of the fourth adjustment member 803 in the fourth waist-shaped hole.

[0124] In one embodiment of the present application, Figure 2 , Figure 8 and Figure 9 As shown, the first driven sliding door mechanism 9 includes a third base 902 and a fourth slider 903. A fourth guide rail is formed on the third base 902. The fourth slider 903 is slidably disposed on the fourth guide rail. The fourth slider 903 is connected to the door panel 21. The length of the fourth guide rail is greater than that of the third guide rail.

[0125] In this embodiment, by providing the first driven sliding door mechanism 9, the fourth slider 903 of the first driven sliding door mechanism 9 can slide along with the door panel 21 when the door panel 21 slides relative to the box door 2, and plays a supporting and auxiliary role in the sliding of the door panel 21, so that the door panel 21 can slide more stably and smoothly relative to the box door 2. At the same time, by making the length of the fourth guide rail greater than the third guide rail, when the door panel 21 slides relative to the box door 2, the third slider 813 slides along the third guide rail, and the fourth slider 903 slides along the fourth guide rail. The fourth guide rail is longer, so that the fourth slider 903 is not easy to fall off the track during the sliding process.

[0126] At the same time, a longer fourth guide rail allows a longer fourth slider 903 to be provided, so that the contact surface between the fourth slider 903 and the door panel 21 is longer, and the first driven sliding door mechanism 9 has a better effect of supporting and assisting the sliding of the door panel 21 .

[0127] It is understandable that if Figure 8 and Figure 9As shown, both ends of the third base 902 of the first driven sliding door mechanism 9 are respectively provided with a fifth fixed seat 901 and a sixth fixed seat 904 for fixedly connecting with the box door 2.

[0128] In an embodiment of the present application, as Figure 2 , Figures 6 to 9 shown, slots for hanging the door panel 21 are provided on the second slider 713, the third slider 813, and the fourth slider 903.

[0129] In this embodiment, by providing slots on the second slider 713, the third slider 813, and the fourth slider 903 for hanging the door panel 21, it is convenient for the user to disassemble and replace the door panel 21 on the active sliding door mechanism 7 and the two driven sliding door mechanisms to meet different usage scenarios of the user.

[0130] Specifically, in an embodiment of the present application, a first connecting block 712 is provided on the second slider 713, and a slot for hanging the door panel 21 is formed on the first connecting block 712; a second connecting block 812 is provided on the third slider 813, and a slot for hanging the door panel 21 is formed on the second connecting block 812; a third connecting block 905 is provided on the fourth slider 903, and a slot for hanging the door panel 21 is formed on the third connecting block 905.

[0131] Correspondingly, a connection component (such as a hook, a plug-in component, etc.) adapted to the slot is provided on the door panel 21.

[0132] In the first embodiment of the present application, as Figure 10 and Figure 11 shown, a first hook 2111 is provided at the top of the door panel 21, and a second hook 2112 is provided at the bottom of the door panel 21. The length of the second hook 2112 is greater than that of the first hook 2111. The first hook 2111 and the second hook 2112 are adapted to be inserted into the corresponding slots.

[0133] In this embodiment, by respectively providing the first hook 2111 and the second hook 2112 at the top and bottom of the door panel 21, the door panel 21 can be connected to the slots of the active sliding door mechanism 7 and the driven sliding door mechanisms through the first hook 2111 and the second hook 2112, so as to slidably connect the door panel 21 with the box door 2. The first hook 2111 and the second hook 2112 are respectively located at the top and bottom of the door panel 21, making it not easy for the door panel 21 to shake.

[0134] In addition, the length of the second hook 2112 is greater than that of the first hook 2111. When the door panel 21 is installed on the outer side of the box door 2, the slot at the bottom is first hooked with the second hook 2112 of the door panel 21 to preliminarily position the bottom of the door panel 21. Then, the position and angle of the door panel 21 are adjusted so that the first hook 2111 at the top of the door panel 21 is inserted into the slot at the top of the box door 2, making it easier for the user to align the slot with the first hook 2111 and the second hook 2112, and the installation is more convenient.

[0135] Specifically, the first hook 2111 includes a connecting portion and a hook portion provided on the connecting portion. The hook portion is in the shape of a hook and is used to be hooked in the slot. At least one waist-shaped hole extending in the horizontal direction and at least one waist-shaped hole extending in the vertical direction are provided on the connecting portion. On the door panel 21, fixing holes are correspondingly provided for the first hook 2111. The door panel 21 and the first hook 2111 are fixedly connected by a fixing member passing through the waist-shaped hole and the fixing hole. By adjusting the position of the fixing member in the waist-shaped hole, the position of the first hook 2111 can be finely adjusted, facilitating the installation of the door panel 21 and finely adjusting the position and angle of the door panel 21.

[0136] It can be understood that the structure of the second hook 2112 is similar to that of the first hook 2111 and will not be elaborated here.

[0137] In an embodiment of the present application, as Figures 12 to 15 shown, the door body assembly further includes: a first end cover 210 and a second end cover 220. The first end cover 210 is provided at one end of the box door 2. A first installation groove 213 and a third installation groove 212 are formed on the first end cover 210. The second driven sliding door mechanism 8 and the active sliding door mechanism 7 are respectively provided in the third installation groove 212 and the first installation groove 213; the second end cover 220 is provided at the other end of the box door 2. A second installation groove is formed on the second end cover 220, and the first driven sliding door mechanism 9 is provided in the second installation groove.

[0138] In this embodiment, by respectively providing the first end cover 210 and the second end cover 220 at both ends of the box door 2, and forming the first installation groove 213 and the third installation groove 212 on the first end cover 210 to respectively install the active sliding door mechanism 7 and the second driven sliding door mechanism 8, and forming the second installation groove on the second end cover 220 to install the first driven sliding door mechanism 9, the structure of the active sliding door mechanism 7, the two driven sliding door mechanisms and the box door 2 is made more compact and beautiful.

[0139] In an embodiment of the present application, as Figure 2 、 Figure 13 and Figure 14As shown, both ends of the first end cap 210 have first hinge holes 211 rotatably connected to the first hinge 4. The first end cap 210 can be connected to the first hinge 4 through the first hinge hole 211 at one of its ends. A first mounting groove 213 is provided on the first end cap 210, and first mounting holes 216 are provided on the wall of the first mounting groove 213. The active sliding door mechanism 7 is fixed to the wall of the first mounting groove 213 through the first mounting holes 216 by bolts. A first avoidance opening 214 is provided on the wall of the first mounting groove 213 facing the box body 1 corresponding to the traction mechanism of the active sliding door mechanism 7. The traction mechanism of the active sliding door mechanism 7 is movably inserted into the first avoidance opening 214 so as to move with the box door 2 to pull the first slider 714.

[0140] A third mounting groove 212 is also provided on the first end cap 210, and the second driven sliding door mechanism 8 is installed in the third mounting groove 212. It can be understood that the positions of the active sliding door mechanism 7 and the second driven sliding door mechanism 8 can be exchanged according to the hinged positions of the box door 2 and the box body 1. Correspondingly, a second avoidance opening 215 for avoiding the traction mechanism of the active sliding door mechanism 7 is also provided on the wall of the third mounting groove 212 facing the box body 1.

[0141] Specifically, third grooves 218 and fourth grooves 219 and first convex ribs 217 for insertion are provided on the opposite side walls of the first mounting groove 213 and the third mounting groove 212, so as to be inserted and fixed with the first main decorative cover 13 or the first sub - decorative cover 17.

[0142] Specifically, as Figure 18 and Figure 19 shown, first notches 1303 and third notches 1304 are respectively provided on the two side end faces of the first main decorative cover 13 corresponding to the first mounting groove 213 and the third mounting groove 212 for the first connection blocks 712 and the second connection blocks 812 of the active sliding door mechanism 7 and the second driven sliding door mechanism 8 to extend out of the notches and be connected to the door panel 21. Fourth notches 1302 and fifth notches 1301 are provided at both ends of the first main decorative cover 13 for the traction mechanism of the active sliding door mechanism 7 to swing with the movement of the box door 2 when installed in the first mounting groove 213 or the third mounting groove 212. A first card slot 1305 is provided on the first main decorative cover 13 corresponding to the first convex rib 217; a first convex rib 1307 for engaging with the wall of the first mounting groove 213 is provided inside the first notch 1303; a second convex rib 1306 for engaging with the wall of the third mounting groove 212 is provided inside the third notch 1304.

[0143] Correspondingly, the structure of the first sub - decorative cover 17 is similar to that of the first main decorative cover 13, but no notches for the first connection block 712 and the second connection block 812 to extend out are provided, which will not be elaborated here.

[0144] On the inner groove wall of the second mounting groove of the second end cover 220, there is a third mounting hole 224. The guide rail fixing seat 221 is installed in the second mounting groove through the third mounting hole 224. The guide rail fixing seat 221 is provided with a second mounting hole 223, and the first driven sliding door mechanism 9 is installed on the guide rail fixing seat 221 through the second mounting hole 223.

[0145] Specifically, on the opposite two side groove walls of the second mounting groove, there are second convex ribs 225 and third convex ribs 227 for insertion, so as to be inserted and fixed with the second main decorative cover 14 or the second sub - decorative cover 18.

[0146] Specifically, in an embodiment of the present application, as Figure 8 、 Figure 9 、 Figure 21 and Figure 22 shown, there are two third connection blocks 905. Correspondingly, on the second main decorative cover 14, there are two second notches 1401 corresponding to the two third connection blocks 905. A cavity for covering the second end cover 220 is formed inside the second main decorative cover 14. At both ends of the cavity, there are a fourth convex rib 1403 and a fifth convex rib 1408, and at the bottom of the cavity, there are a sixth convex rib 1404 and a seventh convex rib 1407. Among them, it is for cooperating and assembling with the third convex rib 227 on the second end cover 220; meanwhile, at the bottom of the cavity, there are also a second card slot 1405 and a third card slot 1406 that cooperate and are inserted with the second convex rib 225, so as to assemble the second end cover 220 and the second main decorative cover 14 together.

[0147] It can be understood that, as Figure 23 shown, when the door panel 21 does not need to be installed, the first driven sliding door mechanism 9 in the second mounting groove can be removed. Correspondingly, at the position of the second sub - decorative cover 18 corresponding to the second mounting groove, there is an inwardly concave handle portion 1801, which is convenient for users to manually open and close the box door 2.

[0148] In another embodiment of the present application, as Figure 1 and Figure 2 shown, a refrigeration device is provided, including: a box body 1 and a door body assembly as provided in any of the above - mentioned 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.

[0149] In this embodiment, the door body assembly includes: a box door 2, a door panel 21, a driving sliding door mechanism 7 and a first driven sliding door mechanism 9. The driving sliding door mechanism 7 is arranged on the box door 2 and is configured to drive the door panel 21 to move in the width direction of the box door 2 during the opening or closing process of the box door 2. The first driven sliding door mechanism 9 is configured to cooperate and guide the movement of the door panel 21 relative to the box door 2.

[0150] By setting a door panel 21 on the cabinet door 2, when the refrigeration equipment is embedded and set in a groove-shaped space, or set between two cabinets, the door panel 21 can be set flush with the cabinets on the side walls or both sides of the groove to reduce the gap between the refrigeration equipment and the adjacent walls or cabinets, making it more beautiful.

[0151] At the same time, when the door 2 rotates, the active sliding door mechanism 7 can drive the door panel 21 to move relative to the door 2 during the rotation of the door 2 to keep away from obstacles such as the wall or cabinet of the side door of the box body 1 as much as possible, so as to prevent these obstacles from blocking the door panel 21 and affecting the rotation of the door 2, resulting in the door 2 being unable to open or close normally. The second driven sliding door mechanism 8 can support and assist the sliding of the door panel 21, so that the sliding of the door panel 21 is more stable and smooth, and it is not easy to shake.

[0152] The combination of the door 2 and the door panel 21 can prevent the door panel 21 from interfering with surrounding objects when the refrigeration device is opened and closed, greatly improving the convenience of use. This design advantage is particularly obvious in a narrow kitchen environment. In addition, the arrangement of the active sliding door mechanism 7 and the first driven sliding door mechanism 9 enables the door panel 21 to move smoothly during the opening and closing process, thereby improving the service life and stability of the refrigerator.

[0153] It can be understood that if the door body assembly has the beneficial effects of the above embodiments, then the refrigeration equipment will correspondingly have the beneficial effects of the above embodiments. The specific implementation methods thereof may refer to the above embodiments, and will not be described in detail in this application.

[0154] like Figure 1 As shown, an application scenario based on the above embodiment is as follows: the refrigeration equipment can be installed in a groove structure in the middle of a cabinet. A door panel 21 is provided on the outside of the door 2 of the cabinet 1 of the refrigeration equipment, and the material and color of the door panel 21 can be designed to be similar or the same as the material color of the outer wall of the cabinet.
