[0085] The door assembly and refrigeration device of the present application are described below with reference to Figures 1 to 23. The door assembly of the present application can be applied to household appliances, such as refrigerators, but it should be understood that the door assembly of the present application can also be applied to dishwashers, washing machines, or any other suitable appliances. The refrigeration device of the present application is applied to a refrigerator, for example, but it should be understood that the refrigeration device of the present application can also be applied to freezers or any other suitable appliances.

[0086] In one embodiment of the present application, as shown in Figures 1 and 2, a door assembly is applied to a refrigeration device, which includes a cabinet 1; the door assembly includes: a cabinet door 2, which is rotatably connected to the cabinet 1 and is suitable for opening or closing the storage space of the cabinet 1; a door panel 21, which is slidably arranged on the outside of the cabinet door 2; an active sliding door mechanism 7 and a traction mechanism, wherein the active sliding door mechanism 7 is arranged on the cabinet door 2, the active sliding door mechanism 7 is transmission-connected to the cabinet 1 through the traction mechanism, and the active sliding door mechanism 7 is transmission-connected to the door panel 21. During the process of opening or closing the cabinet door 2, the cabinet 1 drives 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 relative to the width direction of the cabinet door 2.

[0087] The active sliding door mechanism 7 may include movable components such as a slider and a slide rail that slide relative to each other. The two components that slide relative to each other are connected to the box door 2 and the door panel 21 respectively through a suitable connection method (such as bolt connection, welding, etc.). At the same time, the active sliding door mechanism 7 is connected to the box body 1 through a 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, thereby driving the active sliding door mechanism 7 through the traction mechanism. The active sliding door mechanism 7 can drive the door panel 21 to move relative to the width direction of the box door 2 (as shown by the double-headed arrows in Figure 1) during the rotation of the box door 2 to keep as far away as possible from obstacles such as walls, objects, etc. on the side door of the box body 1, so as to prevent these obstacles from blocking the door panel 21 and affecting the rotation of the box door 2, resulting in the box door 2 being unable to open or close normally.

[0088] It is understood that the width direction of the door 2 is parallel to the plane on which the door 2 is located and perpendicular to the rotation axis of the door 2, so that the door panel 21 can be moved away from or close to the rotation axis of the door 2. It should be noted that the parallel and perpendicular relationships in this application need to take into account the installation errors between various components, and the error of plus or minus 10° should be understood as the scope of protection of the patent.

[0089] Specifically, when the door 2 is rotated to open outside the housing 1 (as indicated by the curved arrow in FIG1 ), the active sliding door mechanism 7 drives the door panel 21 to slide away from the first hinge 4, thereby preventing the door panel 21 from interfering with external obstacles. When the door 2 is rotated to close toward the housing 1, the active sliding door mechanism 7 drives the door panel 21 to slide toward the first hinge 4, thereby preventing the door panel 21 from interfering with obstacles after closing.

[0090] 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, and the door panel 21 is slidably arranged on the outside of the box door 2, and 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 that in the process of the box door 2 rotating to open or close relative to the box body 1, the box body 1 drives 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 relative to the width direction of the box door 2. In the process of opening the box door 2, the door panel 21 is controlled to move toward the outside, and in the process of closing the box door 2, the door panel 21 is controlled to move toward the inside, 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, so as to avoid interference between the door panel 21 and obstacles and affect the rotation of the box door 2, so as to meet the user's usage needs in different scenarios.

[0091] In an embodiment of the present application, as shown in Figures 2, 3, 4 and 5, 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 door 2 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. During 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.

[0092] It should be noted that, in practical applications, the designs of the first slider 714, the second slider 713, and other sliders in this application can be flexible and adaptable 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.

[0093] 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 coefficient, and good stability, such as metal alloys, engineering plastics, or special lubricating materials. These materials are selected to improve the durability of the sliders, reduce wear and noise during sliding, and ensure smooth sliding.

[0094] 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 flat contact, ball contact, or sliding bearing contact. These different contact methods each have advantages and disadvantages. For example, ball contact can reduce friction and wear, but it is more expensive; while flat contact is simple in structure but may require more frequent lubrication and maintenance. Therefore, when selecting a suitable contact method, factors such as usage conditions, cost-effectiveness, and ease of maintenance should be comprehensively considered.

[0095] The connecting member 706 can be a connecting component such as a traction rope, a transmission belt, etc. The two ends of the connecting member 706 are respectively connected to the first slider 714 and the second slider 713, so that the first slider 714 can drive the second slider 713 to move synchronously, and then drive the door panel 21 to slide relative to the box door 2.

[0096] By properly setting the extending direction of the connecting member 706 , the first slider 714 and the second slider 713 move in opposite directions during movement, thereby driving the door panel 21 to avoid obstacles.

[0097] Specifically, when the door 2 is rotated to open outside the housing 1, the housing 1 drives the first slider 714 to slide toward the first hinge 4 via the traction mechanism. Simultaneously, the first slider 714 drives the second slider 713 to slide in the opposite direction (i.e., away from the first hinge 4) via the connecting member 706, thereby preventing the door panel 21 from interfering with external obstacles. When the door 2 is rotated to close toward the side of the housing 1, the housing 1 drives the first slider 714 to slide away from the first hinge 4 via the traction mechanism. Simultaneously, the first slider 714 drives the second slider 713 to slide in the opposite direction (i.e., toward the first hinge 4) via the connecting member 706, thereby preventing the door panel 21 from interfering with obstacles after closing.

[0098] In one embodiment of the present application, as shown in Figures 4 to 6, the door assembly further includes a traction mechanism, which includes a traction rod 709, a first rotation shaft fixing seat 707, and a second rotation shaft fixing seat 710. The first rotation shaft fixing seat 707 is connected to the first slider 714, and the second rotation shaft fixing seat 710 is used to be connected to the box body 1. The first end of the traction rod 709 is rotatably connected to the first rotation shaft fixing seat 707, and the second end of the traction rod 709 is rotatably connected to the second rotation shaft fixing seat 710.

[0099] In this embodiment, the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710 are respectively fixed to the first slider 714 and the box body 1, and the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710 are connected by a traction rod 709, so that the distance between the first slider 714 and the second rotating shaft fixing seat 710 remains 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, so that 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.

[0100] Specifically, the first 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 second end of the traction rod 709 and the second rotating shaft fixing seat 710 are rotatably connected through another pin shaft 708 and another third bearing 715 .

[0101] In one embodiment of the present application, as shown in FIG. 4 to FIG. 6 , a first connecting block 712 is provided on the second sliding block 713 , and a slot for hanging the door panel 21 is formed on the first connecting block 712 .

[0102] In this embodiment, a first connecting block 712 is provided on the second slider 713, and a slot is provided on the first connecting block 712. Accordingly, a connecting component (such as a hook, a connector, etc.) adapted to the slot is provided on the door panel 21, so that the door panel 21 can be mounted on the first connecting block 712 and slide along the second slider 713. At the same time, it is also convenient for the user to remove the door panel 21 from the second slider 713 when needed, meeting the user's usage needs in different scenarios.

[0103] In one embodiment of the present application, as shown in Figures 2, 6, and 9, the door assembly further comprises a driven sliding door mechanism. The driven sliding door mechanism is disposed on the door 2 and comprises 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. The third slider 813 is provided with a second connecting block 812, which has a slot formed in the second connecting block 812 for the door panel 21 to be attached to.

[0104] In this embodiment, a driven sliding door mechanism is provided on the door 2. The driven sliding door mechanism comprises a second base 817, on which is disposed a third guide rail and a third slider 813 capable of sliding along the third guide rail. The third slider 813 is connected to the door panel 21 via a second connecting block 812. The third slider 813 is capable of sliding with the door panel 21 as it slides relative to the door 2, providing support and assisting in the sliding of the door panel 21, thereby ensuring smoother sliding relative to the door 21. Furthermore, the driven sliding door mechanism cooperates with the active sliding door mechanism 7 to restrict the movement of the door panel 21, reducing any shaking during sliding and ensuring more stable sliding. Furthermore, the slots in the second connecting block 812 facilitate the user's installation of the door panel 21 on the driven sliding door mechanism.

[0105] In a specific embodiment, there can be multiple driven sliding door mechanisms, and the multiple driven sliding door mechanisms are respectively arranged at different positions on the box door 2, so as to set multiple auxiliary sliding support points for the door panel 21, so that the door panel 21 can slide more stably and smoothly relative to the box door 2.

[0106] Furthermore, in one embodiment of the present application, as shown in FIG. 6 to FIG. 9 , the driven sliding door mechanism includes a first driven sliding door mechanism 8 and a second driven sliding door mechanism 9 .

[0107] As shown in Figures 2, 6 and 7, the first driven sliding door mechanism 8 is coaxially arranged with the active sliding door mechanism 7. The first 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 arranged on the third guide rail. A second connecting block 812 is provided on the third slider 813. A slot for hanging the door panel 21 is formed on the second connecting block 812.

[0108] By arranging the first driven sliding door mechanism 8 and the active sliding door mechanism 7 coaxially, the third slider 813 can slide coaxially with the active sliding door mechanism 7, thereby better assisting the door panel 21 in sliding relative to the compartment door 2 under the drive of the active sliding door mechanism 7. At the same time, the second connecting block 812 can cooperate with the active sliding door mechanism 7 to limit the movement direction of the door panel 21, thereby preventing the door panel 21 from swinging during movement. The coaxial arrangement of the first driven sliding door mechanism 8 and the active sliding door mechanism 7 means that they share the same center line or axis, which helps ensure that the door panel 21 can maintain stable linear motion during sliding and reduce the possibility of deviation or swinging. The coaxial arrangement is used in situations where it is necessary to precisely control the direction of movement or maintain the relative position relationship between components.

[0109] As shown in Figures 2, 8 and 9, the second driven sliding door mechanism 9 is arranged on an off-axis basis with the active sliding door mechanism 7. The second 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 arranged on the fourth guide rail. A third connecting block 905 is provided on the fourth slider 903. A slot for hanging the door panel 21 is formed on the third connecting block 905.

[0110] By setting up the second driven sliding door mechanism 9, the fourth slider 903 of the second driven sliding door mechanism 9 can slide with the door panel 21 when the door panel 21 slides relative to the box door 2, playing 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.

[0111] At the same time, because the second driven sliding door mechanism 9 is offset from the active sliding door mechanism 7, the third connecting block 905 can cooperate with the active sliding door mechanism 7 to restrict the movement direction of the door panel 21, preventing the door panel 21 from deflecting around the sliding direction during sliding, making the sliding process more stable and reliable. The second driven sliding door mechanism 9 is offset from the active sliding door mechanism 7, meaning that they do not share the same centerline or axis. This configuration is used to provide additional support, stability, or prevent the door panel 21 from deflecting around the sliding direction during sliding. Off-axis configurations are used in situations where it is necessary to disperse force, increase stability, or achieve complex motion trajectories.

[0112] In one embodiment of the present application, as shown in FIG8 and FIG9 , a fifth fixing seat 901 and a sixth fixing seat 904 are respectively provided at both ends of the third base 902 of the second driven sliding door mechanism 9 for fixed connection with the box door 2 .

[0113] In one embodiment of the present application, as shown in Figures 10 and 11, 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 corresponding slots.

[0114] In this embodiment, by providing a first hook 2111 and a second hook 2112 at the top and bottom of the door panel 21, respectively, the door panel 21 can be connected to the slots of the active sliding door mechanism 7 and the driven sliding door mechanism via the first hook 2111 and the second hook 2112, thereby slidably connecting the door panel 21 to the cabinet door 2. The first hook 2111 and the second hook 2112 are located at the top and bottom of the door panel 21, respectively, so that the door panel 21 is not easily shaken.

[0115] 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 outside 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 can be inserted into the slot at the top of the box door 2, making it easier for users to align the slot with the first hook 2111 and the second hook 2112, making installation more convenient.

[0116] Specifically, the first hook 2111 includes a connecting portion and a hook portion disposed on the connecting portion. The hook portion is hook-shaped and is designed to be hooked into a slot. The connecting portion is provided with at least one waist-shaped hole extending horizontally and at least one waist-shaped hole extending vertically. The door panel 21 is provided with a corresponding fixing hole for the first hook 2111. The door panel 21 and the first hook 2111 are fixedly connected by a fixing member that passes through the waist-shaped hole and the fixing hole. By adjusting the position of the fixing member within the waist-shaped hole, the position of the first hook 2111 can be fine-tuned, facilitating installation of the door panel 21 and fine-tuning its position and angle.

[0117] It is understandable that the structure of the second hook 2112 is similar to that of the first hook 2111 and will not be described in detail here.

[0118] In one embodiment of the present application, as shown in Figures 12 to 15, the door body assembly also includes: a first end cover 210 and a second end cover 220, the first end cover 210 is arranged at the first end of the box door 2, a first mounting groove 213 is formed on the first end cover 210, and the active sliding door mechanism 7 is arranged in the first mounting groove 213; the second end cover 220 is arranged at the second end of the box door 2, a second mounting groove is formed on the second end cover 220, and the driven sliding door mechanism is arranged in the second mounting groove.

[0119] In this embodiment, a first end cover 210 and a second end cover 220 are respectively provided at both ends of the box door 2, and a first mounting groove 213 is formed on the first end cover 210 to install the active sliding door mechanism 7, and a second mounting groove is formed on the second end cover 220 to install the driven sliding door mechanism, so that the structure of the active sliding door mechanism 7, the driven sliding door mechanism and the box door 2 becomes more compact and beautiful.

The second main decorative cover 14 is detachably mounted on the second end cap 220 and is formed with a second notch 1401. One end of the second connecting block 812 having a slot passes through the second notch 1401.

[0121] In this embodiment, by providing a first main decorative cover 13 on the first end cover 210, the first main decorative cover 13 can be installed to cover the entire first end cover 210, preventing the first mounting slot 213 and the active sliding door mechanism 7 from being completely exposed, thereby enhancing the appearance. Furthermore, a first notch 1303 is formed on the first main decorative cover 13, allowing the slot end of the active sliding door mechanism 7 to extend outside the first main decorative cover 13 and connect with the door panel 21, thereby driving the door panel 21 to slide. Similarly, by providing a second main decorative cover 14 on the second end cover 220 to cover the entire second end cover 220, the second mounting slot and the driven sliding door mechanism are prevented from being exposed, thereby enhancing the appearance. The slot end of the second connecting block 812 of the driven sliding door mechanism can extend through the second notch 1401 on the second main decorative cover 14 to connect with the door panel 21, thereby assisting the sliding of the door panel 21.

[0122] In one embodiment of the present application, as shown in Figures 14, 18 and 19, one of the first main decorative cover 13 and the first end cover 210 is provided with a first protrusion, and the other is provided with a first groove corresponding to the first protrusion, and the first main decorative cover 13 is detachably connected to the first end cover 210 through the first protrusion and the first groove.

[0123] As shown in Figures 15, 21 and 22, one of the second main decorative cover 14 and the second end cover 220 is provided with a second protrusion, and the other is provided with a second groove corresponding to the second protrusion. The second main decorative cover 14 is detachably connected to the second end cover 220 through the second protrusion and the second groove.

[0124] In this embodiment, a first protrusion is provided on the first end cover 210 and a first groove is provided on the first main decorative cover 13 . The first protrusion and the first groove can be engaged with each other to fix the first main decorative cover 13 and the first end cover 210 to each other.

[0125] It is understandable that the positions of the first protrusion and the first groove can be interchanged, that is, the first end cover 210 is provided with the first groove, and the first main decorative cover 13 is provided with the first protrusion.

[0126] Similarly, as shown in Figures 15, 21 and 22, a second protrusion is provided on the second end cover 220, and a second groove is provided on the second main decorative cover 14. The second protrusion and the second groove can be engaged with each other to fix the second main decorative cover 14 and the second end cover 220 to each other.

[0127] It is understandable that the positions of the second protrusion and the second groove can be interchanged, that is, the first groove is provided on the second end cover 220 and the second main decorative cover 14 is provided with the second protrusion.

[0128] In one embodiment of the present application, as shown in Figures 17, 20, and 23, the door assembly further includes a first decorative cover 17 and a second decorative cover 18. The first decorative cover 17 is detachably mounted on the first end cover 210 to shield the active sliding door mechanism 7; the second decorative cover 18 is detachably mounted on the second end cover 220 to shield the driven sliding door mechanism.

[0129] In this embodiment, in some usage scenarios, there is no need to install a door panel 21 on the outside of the box door 2. The first auxiliary decorative cover 17 can be used to replace the first main decorative cover 13 on the first end cover 210, and the second auxiliary decorative cover 18 can be used to replace the second main decorative cover 14 on the second end cover 220, respectively, to cover the active sliding door mechanism 7 and the driven sliding door mechanism, so as to improve the visual consistency of the box door 2, make it more beautiful, and meet the different usage needs of users.

[0130] Similar to the first main decorative cover 13 and the second main decorative cover 14, the first auxiliary decorative cover 17, the second auxiliary decorative cover 18 and the first end cover 210 and the second end cover 220 can also be snap-fitted by means of grooves and protrusions for easy assembly and disassembly, which will not be described in detail here.

[0131] In one embodiment of the present application, as shown in Figures 2, 13, and 14, both ends of the first end cover 210 have first hinge holes 211 rotatably connected to the first hinge 4. The first end cover 210 can be connected to the first hinge 4 via the first hinge hole 211 at one end. The first end cover 210 is provided with a first mounting slot 213, and the wall of the first mounting slot 213 is provided with a first mounting hole 216. The active sliding door mechanism 7 is fixed to the wall of the first mounting slot 213 via bolts through the first mounting hole 216. A first avoidance opening 214 is provided on the wall of the first mounting slot 213 facing the housing 1, corresponding to the traction mechanism of the active sliding door mechanism 7. The traction mechanism of the active sliding door mechanism 7 can be movably inserted into the first avoidance opening 214 so as to move with the door 2 to pull the first slider 714.

[0132] The first end cover 210 is further provided with a third mounting slot 212, into which the first driven sliding door mechanism 8 is mounted. It is understood that the positions of the active sliding door mechanism 7 and the first driven sliding door mechanism 8 can be swapped depending on the hinge position of the door 2 and the housing 1. Accordingly, a second avoidance opening 215 is also provided on the wall of the third mounting slot 212 facing the housing 1 to allow the traction mechanism of the active sliding door mechanism 7 to avoid movement.

[0133] Specifically, a third groove 218 and a fourth groove 219 and a first ridge 217 for plugging are provided on the groove walls on opposite sides of the first installation groove 213 and the third installation groove 212 so as to be plugged and fixed with the first main decorative cover 13 or the first auxiliary decorative cover 17 .

[0134] Specifically, as shown in Figures 18 and 19, the first main decorative cover 13 has first and third notches 1303 and 1304 on its two side surfaces, corresponding to the first and third mounting slots 213 and 212, respectively. These allow the first and second connecting blocks 712, 812 of the active sliding door mechanism 7 and the first driven sliding door mechanism 8 to extend through the notches and connect to the door panel 21. A fourth and fifth notches 1302 and 1301 are provided at both ends of the first main decorative cover 13, allowing the traction mechanism of the active sliding door mechanism 7 to swing with the movement of the door 2 when installed in the first and third mounting slots 213, 212, respectively. A first engaging groove 1305 is provided on the first main decorative cover 13, corresponding to the first ridge 217. A first rib 1307 is provided inside the first notch 1303 for engaging with the walls of the first mounting slot 213. A second rib 1306 is provided inside the third notch 1304 for engaging with the walls of the third mounting slot 212.

[0135] Correspondingly, the structure of the first auxiliary decorative cover 17 is similar to that of the first main decorative cover 13 , but no notch is provided for the first connecting block 712 and the second connecting block 812 to extend out, which will not be described in detail here.

[0136] A third mounting hole 224 is provided on the inner wall of the second mounting groove of the second end cover 220, and the guide rail fixing seat 221 is installed in the second mounting groove through the third mounting hole 224. A second mounting hole 223 is provided on the guide rail fixing seat 221, and the second driven sliding door mechanism 9 is installed on the guide rail fixing seat 221 through the second mounting hole 223.

[0137] Specifically, a second ridge 225 and a third ridge 227 for plugging are provided on the groove walls on opposite sides of the second installation groove so as to be plugged and fixed to the second main decorative cover 14 or the second auxiliary decorative cover 18 .

[0138] Specifically, in one embodiment of the present application, as shown in Figures 8, 9, 21 and 22, there are two third connecting blocks 905, and accordingly, two second notches 1401 are provided on the second main decorative cover 14 corresponding to the two third connecting blocks 905, and a cavity for covering the second end cover 220 is formed in the second main decorative cover 14, and a fourth ridge 1403 and a fifth ridge 1408 are provided at both ends of the cavity, and a sixth ridge 1404 and a seventh ridge 1407 are provided at the bottom of the cavity, so as to cooperate with the third ridge 227 on the second end cover 220; at the same time, a second card groove 1405 and a third card groove 1406 that cooperate with the second ridge 225 are also provided at the bottom of the cavity, so as to assemble the second end cover 220 and the second main decorative cover 14 together.

[0139] It is understandable that, as shown in Figure 23, when there is no need to install the door panel 21, the second driven sliding door mechanism 9 in the second installation groove can be removed. Accordingly, the second auxiliary decorative cover 18 is provided with a concave buckle portion 1801 at the position corresponding to the second installation groove, which is convenient for users to manually open and close the box door 2.

[0140] In one embodiment of the present application, as shown in Figures 3, 4, and 5, the connector 706 includes a first connector and a second connector. The first connector bypasses the first end of the first base 717, with its two ends respectively connected to the first ends of the first slider 714 and the second slider 713; the second connector bypasses the second end of the first base 717, with its two ends respectively connected to the second ends of the first slider 714 and the second slider 713.

[0141] In this embodiment, the first connecting member is connected to the first slider 714 and the second slider 713 by passing one end of the first base 717 around the first connecting member. When the first slider 714 slides in the direction away from the end of the first base 717 under the drive of the box body 1 and the traction mechanism, the first slider 714 drives the second slider 713 to slide in the direction close to the end of the first base 717 through the first connecting member. At the same time, the second connecting member is connected to the first slider 714 and the second slider 713 by passing the other end of the second connecting member around the first base 717. When 14 slides toward the other end away from the first base 717 under the drive of the box body 1 and the traction mechanism, the first slider 714 drives the second slider 713 to slide toward the other end close to the first base 717 through the second connecting member, thereby achieving that when the first slider 714 slides toward both ends of the first base 717 respectively, the second slider 713 and the first slider 714 can be driven to slide in the opposite direction, thereby enabling the door panel 21 to slide relative to the box door 2 as the box door 2 rotates when the box door 2 is opened and closed, so as to avoid interference with obstacles and affecting the opening and closing of the box door 2.

[0142] Specifically, the second slider 713 and the first slider 714 are both provided with a connecting head 711 for fixing the connecting member 706 .

[0143] In one embodiment of the present application, as shown in Figures 3, 4 and 5, the active sliding door mechanism 7 also includes: a first fixed seat 701 and a second fixed seat 702, the first fixed seat 701 is connected to the first 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 the first ends of the first guide rail and the second guide rail, and a part of the first connecting member is slidably set in the first limiting groove; the second fixed seat 702 is connected to the second 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 second ends of the first guide rail and the second guide rail, and a part of the second connecting member is slidably set in the second limiting groove.

[0144] In this embodiment, by arranging the first fixing seat 701 and the second fixing seat 702 at both ends of the first base 717, the first fixing seat 701 and the second fixing seat 702 are respectively formed with the first limiting groove and the second limiting groove docking with the first guide rail and the second guide rail, respectively limiting and guiding the positions of the first connecting member and the second connecting member, so that the sliding of the first connecting member and the second connecting member is smoother.

[0145] Specifically, a first fixing hole is provided on the first fixing seat 701, and 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 also includes a first adjusting member 704, which 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 by adjusting the position of the first adjusting member 704 in the first waist-shaped hole.

[0146] In this embodiment, by adjusting the position of the first adjusting member 704 in the first waist-shaped hole, the position of the first fixing seat 701 can be adjusted along the width direction of the first base 717, so that the first fixing seat 701 can tighten or loosen the first connecting member, thereby adjusting the tightness of the first connecting member.

[0147] 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 first slider 714 and the two ends of the second slider 713, when the first fixing seat 701 is adjusted to move relative to the first base 717 through the first waist-shaped hole, the first connecting member adjusts the tightness accordingly, and the second connecting member also adjusts the tightness accordingly under the pulling of the first fixing seat 701 on the first connecting member.

At the same time, the second adjusting member 703 can be fine-tuned along the position of the second waist-shaped hole to adjust the position of the first fixing base 701, thereby coordinating the adjustment of the position of the first fixing base 701 relative to the external structure.

[0153] It is understood that the second fixing base 702 may also be provided with a second waist-shaped hole extending along the width direction of the first base 717; the second adjustment member 703 is sequentially passed through the second waist-shaped hole and the second fixing hole to be fixed to the external structure, so that the position of the second fixing base 702 relative to the external structure is adjusted by the position of the second adjustment member 703 in the second waist-shaped hole. The functions of the second adjustment member 703, the second waist-shaped hole, and the second fixing hole are similar to those in the above embodiment and will not be further described here.

[0154] Furthermore, in some embodiments, a rotatable support bearing is provided in the first limiting groove; a portion of the first connecting member abuts against the support bearing in the first limiting groove. In this embodiment, by abutting a portion of the first connecting member against the support bearing, the movement and extension direction of the first connecting member can be adjusted, thereby facilitating the first connecting member to pass around the end of the first base 717 and connect to the first slider 714 and the second slider 713.

[0155] It is understandable that a rotatable support bearing may also be provided in the second limiting groove; a portion of the second connecting member abuts against the support bearing in the second limiting groove to adjust the extension direction of the second connecting member, making it convenient to connect the second connecting member around the end of the first base 717 and the first slider 714 and the second slider 713.

[0166] 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 when it is 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 wall or cabinet, making it more beautiful.

[0167] 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 stay as far away as possible from obstacles such as the wall or cabinet of 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, causing the box door 2 to be unable to open or close normally.

[0168] The combination of door 2 and door panel 21 prevents interference between the door panel 21 and surrounding objects during opening and closing, significantly improving ease of use. This design advantage is particularly evident in confined kitchen environments. Furthermore, the active sliding door mechanism 7 ensures smooth movement of the door panel 21 during opening and closing, extending the lifespan and stability of the refrigerator.

[0169] It can be understood that if the door assembly has the beneficial effects of the above embodiments, then the refrigeration equipment will correspondingly have the beneficial effects of the above embodiments.

A door panel 21 is provided on the outside of the door 2 of the cabinet body 1 of the refrigeration equipment. 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. When the door 2 is closed, the door panel 21 is flush with the outer wall of the cabinet at the edge of the opening of the groove-shaped structure, and fits as closely as possible with 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 the gap is small, which is more beautiful.

[0171] When the door 2 is rotated outward to open, the active sliding door mechanism 7 drives the door panel 21 to slide away from the first hinge 4 to prevent the door panel 21 from interfering with the cabinet wall on the side close to the first hinge 4, which would prevent the door 2 from opening to a wider angle. When the door 2 is rotated to close, the active sliding door mechanism 7 drives the door panel 21 to slide toward the first hinge 4 to prevent the door panel 21 from interfering with the cabinet wall on the side away from the first hinge 4, which would prevent the door 2 from being fully closed and affect the refrigeration and preservation effect of the storage space.
