Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0030] Combine the following Figures 1 to 23 The door assembly and refrigeration device of the present application are described. 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 devices. The refrigeration device of the present application is applied to refrigerators, 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 devices.

[0031] In one embodiment of the present application, Figure 1 and Figure 2As shown, the door assembly is applied to a refrigeration device, and the refrigeration device 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.

[0032] The active sliding door mechanism 7 may include movable parts such as a slider and a slide rail that slide relative to each other. The two parts that can slide relative to each other are respectively connected to the door 2 and the door panel 21 by 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 by a traction mechanism. In this way, when the door 2 rotates to open and close, the box body 1 rotates relative to the door 2, so that the active sliding door mechanism 7 is driven by the traction mechanism, so that the active sliding door mechanism 7 can drive the door panel 21 to move relative to the width direction of the door 2 during the rotation of the door 2 (such as Figure 1 As shown by the double-headed arrows in the figure, the door 2 is kept as far away from obstacles such as walls, objects, etc. of the side door of the cabinet 1 as possible to prevent these obstacles from blocking the door panel 21 and affecting the rotation of the cabinet door 2, causing the cabinet door 2 to be unable to be opened or closed normally.

[0033] 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. It should be noted that the parallel and perpendicular relationship of this application needs to take into account the installation error between various components, and the error of plus or minus 10° should be understood as the scope of protection of the patent.

[0034] Specifically, during the process of the door 2 rotating toward the outside of the box body 1 to open (eg Figure 1 In the process of the door 2 rotating toward the side of the box body 1 to close, the active sliding door mechanism 7 drives the door panel 21 to slide toward the first hinge 4, thereby avoiding interference between the door panel 21 and obstacles outside. In the process of the door 2 rotating toward the side of the box body 1 to close, the active sliding door mechanism 7 drives the door panel 21 to slide toward the first hinge 4, thereby avoiding interference between the door panel 21 and obstacles after closing.

[0035] 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 arranged on the box door 2, and the active sliding door mechanism 7 is respectively connected to the box door 2 and the door panel 21, so that when the box door 2 is rotated 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 in the width direction of the box door 2. When the box door 2 is opened, the door panel 21 is controlled to move outward, and when the box door 2 is closed, the door panel 21 is controlled to move inward, so that the door panel 21 can avoid obstacles such as side walls and objects during the closing or opening of the box door 2, so as to avoid the interference of the door panel 21 with obstacles and affect the rotation of the box door 2, so as to meet the user's usage needs in different scenarios.

[0036] 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 door 2 and slidably disposed on the first guide rail. The second slider 713 is connected to the door panel 21 and 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.

[0037] 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.

[0038] From the material point of view, the first slider 714 and the second slider 713 as well as other sliders in the present application can be made of materials with high wear resistance, low friction coefficient and good stability, such as metal alloys, engineering plastics or special lubricating materials. The selection of these materials is intended to improve the durability of the slider, reduce wear and noise during sliding, and ensure smooth sliding.

[0039] In terms of structural design, the first slider 714, the second slider 713 and other sliders in the present application can adopt various forms of guide rail contact surfaces, such as plane contact, ball contact or sliding bearing contact. These different contact methods have their own advantages and disadvantages. For example, ball contact can reduce friction and wear, but the cost is high; while plane contact has a simple structure, but may require more frequent lubrication and maintenance. Therefore, factors such as usage conditions, cost-effectiveness and maintenance convenience should be comprehensively considered when selecting.

[0040] 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, thereby driving the door panel 21 to slide relative to the box door 2.

[0041] By properly setting the extending direction of the connecting member 706, the first sliding block 714 and the second sliding block 713 move in opposite directions during movement, so as to drive the door panel 21 to avoid obstacles.

[0042] Specifically, when the door 2 is rotated to the outside of the box body 1 to open, the box body 1 drives the first slider 714 to slide in the direction close to the first hinge 4 through the traction mechanism, and 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, thereby avoiding interference between the door panel 21 and obstacles on the outside. When the door 2 is rotated to one side of the box body 1 to close, the box body 1 drives the first slider 714 to slide in the direction away from the first hinge 4 through the traction mechanism, and 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, thereby avoiding interference between the door panel 21 and obstacles after closing.

[0043] In one embodiment of the present application, Figures 4 to 6 As shown, the door assembly further includes a traction mechanism, which 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 sliding block 714, and the second rotating shaft fixing seat 710 is used to be connected to the box 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.

[0044] 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 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 through 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.

[0045] Specifically, one end of the traction rod 709 is rotatably connected to the first rotating shaft fixing seat 707 via a pin shaft 708 and a third bearing 715 , and the other end is rotatably connected to the second rotating shaft fixing seat 710 via another pin shaft 708 and another third bearing 715 .

[0046] In one embodiment of the present application, Figures 4 to 6 As shown, a first connecting block 712 is disposed on the second sliding block 713 , and a slot for hanging the door panel 21 is formed on the first connecting block 712 .

[0047] In this embodiment, by providing the first connection block 712 on the second slider 713 and providing a slot on the first connection block 712, correspondingly, the door panel 21 is provided with a connection component (such as a hook, a connector, etc.) adapted to the slot, so that the door panel 21 is installed on the first connection block 712, so that the door panel 21 can slide with 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.

[0048] In one embodiment of the present application, Figure 2 , Figures 6 to 9 As shown, the door assembly further includes: a driven sliding door mechanism. The driven sliding door mechanism is arranged on the box door 2, and 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 arranged on the third guide rail. The third slider 813 is provided with a second connecting block 812, and the second connecting block 812 is formed with a slot for the door panel 21 to be hung.

[0049] In this embodiment, a driven sliding door mechanism is provided on the box door 2, and the driven sliding door mechanism has a second base 817, and a third guide rail and a third slider 813 that can slide along the third guide rail are provided on the second base 817, and the third slider 813 is connected to the door panel 21 through the second connecting block 812. The third slider 813 can slide 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 smoothly relative to the box door 2. At the same time, the driven sliding door mechanism can cooperate with the active sliding door mechanism 7 to limit the movement direction of the door panel 21, reduce the shaking of the door panel 21 during the sliding process, and slide more stably. In addition, the slot on the second connecting block 812 can facilitate the user to install the door panel 21 on the driven sliding door mechanism.

[0050] 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.

[0051] Further, in one embodiment of the present application, Figures 6 to 9 The driven sliding door mechanism shown includes a first driven sliding door mechanism 8 and a second driven sliding door mechanism 9 .

[0052] Among them, Figure 2 , Figure 6 and Figure 7 As shown, the first driven sliding door mechanism 8 is coaxially arranged with the active sliding door mechanism 7, and 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, and a slot for hanging the door panel 21 is formed on the second connecting block 812.

[0053] 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, so as to better assist 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 second connecting block 812 can cooperate with the active sliding door mechanism 7 to limit the movement direction of the door panel 21 to prevent the door panel 21 from swinging during the 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 to ensure that the door panel 21 can maintain stable linear motion during the sliding process and reduce the possibility of deviation or swinging. The coaxial arrangement is used in situations where the movement direction needs to be precisely controlled or the relative position relationship between components needs to be maintained.

[0054] like Figure 2 , Figure 8 and Fig. 9As shown, the second driven sliding door mechanism 9 is arranged off-axis from the active sliding door mechanism 7, and 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, and a slot for hanging the door panel 21 is formed on the third connecting block 905.

[0055] By setting the second driven sliding door mechanism 9, the fourth sliding block 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, and plays a supporting and auxiliary role in the sliding of the door panel 21, so that the door panel 21 can slide relative to the box door 2 more stably and smoothly.

[0056] At the same time, since the second driven sliding door mechanism 9 and the active sliding door mechanism 7 are arranged off-axis, the third connecting block 905 can cooperate with the active sliding door mechanism 7 to limit the movement direction of the door panel 21, so as to prevent the door panel 21 from deflecting around the sliding direction when sliding, and the sliding process is more stable and reliable. The second driven sliding door mechanism 9 and the active sliding door mechanism 7 are arranged off-axis, which means that 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 sliding. The off-axis setting is used in situations where it is necessary to disperse force, increase stability or achieve complex motion trajectories.

[0057] In one embodiment of the present application, Figure 8 and Fig. 9 As shown, a fifth fixing seat 901 and a sixth fixing seat 904 are respectively provided at two ends of the third base 902 of the second driven sliding door mechanism 9 for fixed connection with the box door 2 .

[0058] In one embodiment of the present application, Fig.10 and Fig.11 As 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 suitable for being inserted into corresponding slots.

[0059] In this embodiment, by respectively arranging the first hook 2111 and the second hook 2112 at the top and the 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 mechanism through the first hook 2111 and the second hook 2112, so that the door panel 21 is slidably connected to the box door 2. The first hook 2111 and the second hook 2112 are respectively located at the top and the bottom of the door panel 21, so that the door panel 21 is not easy to shake.

[0060] 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 the user to align the slot with the first hook 2111 and the second hook 2112, making installation more convenient.

[0061] Specifically, the first hook 2111 includes a connecting portion and a hook portion disposed on the connecting portion. The hook portion is in the shape of a hook and is used to be hung in a slot.

The door panel 21 is provided with a fixing hole corresponding to 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 fine-tuned, which is convenient for installing the door panel 21 and fine-tuning the position and angle of the door panel 21.

[0062] 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 herein.

[0111] 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.

[0112] 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 active sliding door mechanism 7 is provided so that the door panel 21 can move smoothly during the opening and closing process, thereby improving the service life and stability of the refrigerator.

When the door 2 is closed, the door panel 21 is flush with the outer wall of the cabinet at the opening edge of the groove structure, and fits the opening of the groove structure as closely as possible, 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.

[0115] When the door 2 is rotated outward to open, the active sliding door mechanism 7 drives the door panel 21 to slide in the direction away from the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall on the side close to the first hinge 4, which causes the door 2 to be unable to open to a larger angle. When the door 2 is rotated to close, the active sliding door mechanism 7 drives the door panel 21 to slide in the direction close to the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall on the side away from the first hinge 4, which causes the door 2 to be unable to be completely closed and affects the refrigeration preservation effect in the storage space.
