[0055] Next, in conjunction with Figures 1 to 5The sliding door device, door assembly and refrigeration equipment of the present application are described. The sliding door device and door assembly of the present application can be applied to the door or cabinet door of household appliances, such as the door of a refrigerator, but it should be understood that the door panel mechanism and door assembly of the present application can also be applied to a dishwasher, a washing machine or any other suitable equipment. The refrigeration equipment of the present application is applied to a refrigerator, for example, but it should be understood that the refrigeration equipment of the present application can also be applied to a freezer or any other suitable equipment.

[0056] In one embodiment of the present application, Figures 1 to 5 As shown, the sliding door device is applied to a refrigeration device, and is used to be arranged on a door 2 with a door panel 21 on the outside, the door 2 is rotatably connected to the box body 1, and the door 2 is suitable for opening or closing the storage space of the box body 1; the sliding door device includes: an active sliding door mechanism 7, including: a first base, a traction mechanism, a first slider 715, a second slider 709 and a connecting member; the first base is used to be arranged on the door 2, one side of the first base is formed with a first guide rail 710, and the other side is formed with a second guide rail 705; the first slider 715 is slidably arranged on the first guide rail 710, and the first slider 715 is transmission-connected to the box body 1 through the traction mechanism; the second slider 709 is slidably arranged on the first guide rail 710 Two guide rails 705; the two ends of the connecting member are respectively connected to the first slider 715 and the second slider 709; at least two driven sliding door mechanisms 9 and a first connecting rod 11, the driven sliding door mechanism 9 includes a second base 917 and a third slider 913; the second base 917 is used to be set on the box door 2, and a third guide rail is formed on the second base 917, and the third slider 913 is slidably set on the third guide rail; the first connecting rod 11 is connected to all the third sliders 913, and the second slider 709 and all the third sliders 913 are used to connect with the door panel 21, so as to cooperate and guide the door panel 21 to move relative to the width direction of the box door 2 during the process of opening or closing the box door 2.

[0057] It is understandable that the width direction of the door 2 is parallel to the plane where the door 2 is located and perpendicular to the rotation axis of the door 2, so that the door panel 21 can be away from or close to the rotation axis of the door 2 (such as Figure 2 It should be noted that the parallel and perpendicular relationship of the present application needs to take into account the installation error between the various components, and the error of plus or minus 10° should be understood as the scope of protection of the patent.

[0058] It is understandable that if Figure 1 , Figures 3 to 5 As shown, the active sliding door mechanism 7 of this embodiment can be arranged on the box door 2, the first slider 715 is connected to the box body 1 through a traction mechanism, and the second slider 709 is slidably connected to the door panel 21 arranged on the outside of the box door 2, so that when the box door 2 rotates, the two sliders slide relative to each other to drive the door panel 21 to slide relative to the box door 2, so that the door panel 21 can avoid obstacles on both sides when the box door 2 is turned on and off.

[0059] Specifically, the first base of this embodiment can be arranged on the door 2 of the cabinet. The connecting member can be a connecting component such as a traction rope or a transmission belt. The two ends of the connecting member are respectively connected to the first slider 715 and the second slider 709, so that the first slider 715 can drive the second slider 709 to move synchronously, and then drive the door panel 21 to slide relative to the door 2 of the cabinet.

[0060] By reasonably setting the extension direction of the connecting member, the first slider 715 and the second slider 709 move in opposite directions during movement, so as to drive the door panel 21 to avoid obstacles.

[0061] Specifically, during the process of the door 2 of the cabinet rotating outward to open, the cabinet 1 drives the first slider 715 to slide towards the direction close to the first hinge 4 through the traction mechanism. At the same time, the first slider 715 drives the second slider 709 to slide in the opposite direction (i.e., away from the first hinge 4) through the connecting member, so as to prevent the door panel 21 from interfering with the obstacles outside. During the process of the door 2 of the cabinet rotating towards one side of the cabinet 1 to close, the cabinet 1 drives the first slider 715 to slide away from the first hinge 4 through the traction mechanism. At the same time, the first slider 715 drives the second slider 709 to slide in the opposite direction (i.e., towards the first hinge 4) through the connecting member, so as to prevent the door panel 21 from interfering with the obstacles after closing.

[0062] At the same time, the third slider 913 of the driven sliding door mechanism 9 can slide along the third guide rail. The third slider 913 is connected to the door panel 21. The third slider 913 can slide along with the door panel 21, playing a role in supporting and assisting the sliding of the door panel 21, and cooperating 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 shaking during the movement process. In addition, the third sliders 913 of all the driven sliding door mechanisms 9 are connected to each other through the first connecting rod 11 to increase the synchronization of the sliding of the third sliders 913 of all the driven sliding door mechanisms 9, making the sliding of the door panel 21 more stable.

[0063] According to the sliding door device 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 an 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, so that during the process of the box door 2 rotating and opening or closing relative to the box body 1, the door panel 21 is driven to slide in the width direction of the box door 2, enabling the door panel 21 to avoid obstacles such as side walls and objects during the closing or opening process of the box door 2, to meet the usage requirements of users in different scenarios. At the same time, by arranging a driven sliding door mechanism 9 to support and assist the sliding of the door panel 21, the sliding of the door panel 21 is more stable and smooth, and the usage effect is better. In addition, the third sliders 913 of all the driven sliding door mechanisms 9 are connected by a first connecting rod 11, making the sliding synchronization of the connected sliders better, and thus making the sliding of the door panel 21 more stable.

[0064] It should be noted that in practical applications, the designs of the first slider 715, the second slider 709, and other sliders in the present application can be flexible and variable to adapt to different working scenarios and performance requirements. They are not limited to specific shapes, sizes, or materials, but can be customized and optimized according to specific needs.

[0065] From the perspective of materials, the first slider 715, the second slider 709, and other sliders in the present application can select materials with high wear resistance, low friction coefficient, and good stability, such as metal alloys, engineering plastics, or special lubricating materials. The selection of these materials aims to improve the durability of the sliders, reduce wear and noise during the sliding process, and ensure the smoothness of the sliding.

[0066] In terms of structural design, the first slider 715, the second slider 709, and other sliders in the present application can adopt various forms of guide rail contact surfaces, such as plane contact, ball contact, or sliding bearing contact, etc. These different contact methods have their own advantages and disadvantages. For example, ball contact can reduce friction and wear, but the cost is relatively high; while plane contact has a simple structure, but may require more frequent lubrication and maintenance. Therefore, when selecting, factors such as usage conditions, cost-effectiveness, and maintenance convenience should be comprehensively considered.

[0067] In an embodiment of the present application, as Figure 3 shown, each driven sliding door mechanism 9 further includes: a fixed seat and a fixing member. The fixed seat is connected to the corresponding second base 917, and the fixed seat is provided with a fixing hole, and the fixing member passes through the fixing hole to be connected to an external structure.

[0068] In this embodiment, by arranging a fixed seat on the second base 917, and the fixed seat is provided with a fixing hole for the fixing member to pass through, the fixed seat is fixed on an external structure (such as the box door 2), thereby fixing the driven sliding door mechanism 9 on the box door 2.

[0069] In one embodiment of the present application, as Figure 3 shown, there are two fixing seats, namely a first fixing seat 904 and a second fixing seat 911. The first fixing seat 904 is connected to one end of the second base 917; the second fixing seat 911 is connected to the other end of the second base 917.

[0070] In this embodiment, by respectively arranging the first fixing seat 904 and the second fixing seat 911 at both ends of the second base 917, both the first fixing seat 904 and the second fixing seat 911 can be fixed to an external structure (such as the box door 2) through the fixing holes thereon, so as to respectively fixedly connect both ends of the second base 917 to the external structure, making the connection between the driven sliding door mechanism 9 and the external structure more stable.

[0071] In one embodiment of the present application, as Figure 3 、 Figure 4 and Figure 5 shown, at least one of the second slider 709, the third slider 913 and the first connecting rod 11 is provided with a slot for hanging the door panel 21.

[0072] In this embodiment, by providing a slot for hanging the door panel 21 on at least one of the second slider 709, the third slider 913 and the first connecting rod 11, it is convenient for the user to hang the door panel 21 on the sliding door device, so that the door panel 21 can slide relative to the box body 1 under the drive of the sliding door device.

[0073] Specifically, in one embodiment of the present application, as Figure 3 shown, each driven sliding door mechanism 9 further includes a first ball support member. The first ball support member is slidably internally connected to the third guide rail, and the third slider 913 is slidably internally connected to the first ball support member.

[0074] In this embodiment, by arranging the first ball support member between the third slider 913 and the third guide rail, the first ball support member can slide along the third guide rail as the third slider 913 slides, so as to remain between the third slider 913 and the third guide rail. The first ball support member can convert at least part of the friction between the third slider 913 and the third guide rail into rolling friction, making the sliding of the third slider 913 smoother.

[0075] Specifically, in one embodiment of the present application, as Figure 3 shown, the first ball support member includes: a first ball (not shown in the figure) and a first support frame 914. A first limiting notch is formed on the first support frame 914. The first ball is rotatably arranged in the corresponding first limiting notch. One side of the first ball abuts against the corresponding third guide rail, and the other side of the first ball passes through the first limiting notch and abuts against the third slider 913.

[0076] Optionally, in some embodiments of the present application, as Figure 4 and Figure 5 shown, the active sliding door mechanism 7 further includes: a second ball support member and a third ball support member. The second ball support member is slidably internally connected to the first guide rail 710, and the first slider 715 is slidably internally connected to the second ball support member. The third ball support member is slidably internally connected to the corresponding second guide rail 705, and the second slider 709 is slidably internally connected to the third ball support member.

[0077] In this embodiment, by providing a second ball support member between the first slider 715 and the first guide rail 710, the second ball support member can slide along the first guide rail 710 as the first slider 715 slides, so as to remain between the first slider 715 and the first guide rail 710. The second ball support member can convert at least part of the friction between the first slider 715 and the first guide rail 710 into rolling friction, making the sliding of the first slider 715 smoother; similarly, the third ball support member is slidably disposed between the second slider 709 and the second guide rail 705, and can convert at least part of the friction between the second slider 709 and the second guide rail 705 into rolling friction, making the sliding of the second slider 709 also smoother, thereby making the relative sliding between the box door 2 and the door panel 21 smoother.

[0078] Specifically, in an embodiment of the present application, as Figure 4 and Figure 5 shown, the second ball support member includes: a second ball (not shown in the figure) and a second support frame 714; the third ball support member includes: a third ball (not shown in the figure) and a third support frame 707. A second limit notch is formed on the second support frame 714, the second ball is rotatably disposed in the corresponding second limit notch, one side of the second ball abuts against the corresponding first guide rail 710, and the other side of the second ball passes through the corresponding second limit notch and abuts against the first slider 715. A third limit notch is formed on the third support frame 707, the third ball is rotatably disposed in the corresponding third limit notch, one side of the third ball abuts against the corresponding second guide rail 705, and the other side of the third ball passes through the corresponding third limit notch and abuts against the second slider 709.

[0079] In this embodiment, a second support frame 714 is provided between the first slider 715 and the first guide rail 710. A second limiting notch is formed on the second support frame 714 to set the second ball for limiting the second ball and preventing the second ball from rolling and shifting, so that the sliding of the first slider 715 is more stable and reliable. Both sides of the second ball are respectively in contact with the first guide rail 710 and the first slider 715. When the first slider 715 rolls relative to the first guide rail 710, the second ball can roll to convert at least part of the friction received by the first slider 715 into rolling friction, making the sliding of the first slider 715 smoother. Similarly, a third support frame 707 is provided between the second slider 709 and the second guide rail 705. A third limiting notch is formed on the third support frame 707 to set the third ball for limiting the third ball and preventing the third ball from rolling and shifting, so that the sliding of the second slider 709 is more stable and reliable. Both sides of the third ball are respectively in contact with the second guide rail 705 and the second slider 709. When the second slider 709 rolls relative to the second guide rail 705, the third ball can roll to convert at least part of the friction received by the second slider 709 into rolling friction, making the sliding of the second slider 709 smoother.

[0080] Optionally, a plurality of second balls and third balls are provided.

[0081] In an embodiment of the present application, as Figure 4 and Figure 5 shown, the connecting member includes: a first connecting member 706 and a second connecting member 712. The first connecting member 706 bypasses one end of the first base, and both ends are respectively connected to one end of the first slider 715 and the second slider 709; the second connecting member 712 bypasses the other end of the first base, and both ends are respectively connected to the other end of the first slider 715 and the second slider 709.

[0082] In this embodiment, the first connecting member 706 is connected to the first slider 715 and the second slider 709 by passing one end of the first base around the first base. When the first slider 715 slides in the direction away from the end of the first base under the drive of the box body 1 and the traction mechanism, the first slider 715 drives the second slider 709 to slide in the direction close to the end of the first base through the first connecting member 706. At the same time, the second connecting member 712 is connected to the first slider 715 and the second slider 709 by passing the other end of the second connecting member 712 around the first base. When block 715 slides toward the other end away from the first base under the drive of the box body 1 and the traction mechanism, the first slider 715 drives the second slider 709 to slide toward the other end close to the first base through the second connecting member 712, thereby achieving that when the first slider 715 slides toward the two ends of the first base respectively, the second slider 709 and the first slider 715 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.

[0083] In another embodiment of the present application, Figures 1 to 5 As shown, a door assembly is provided, comprising: a box door 2, a door panel 21, and a sliding door device as provided in any of the above embodiments. The box door 2 is rotatably connected to the box body 1, and is suitable for opening or closing the storage space of the box body 1. The door panel 21 is slidably arranged on the outside of the box door 2; the sliding door device is arranged on the box door 2, the first slider 715 is transmission-connected to the box body 1 through a traction mechanism, and the second slider 709 and the third slider 913 are both connected to the door panel 21. In the process of opening or closing the box door 2, the first slider 715 moves in opposite directions to the second slider 709 and the third slider 913 to drive the door panel 21 to move relative to the width direction of the box door 2.

[0084] In this embodiment, during the process of the door 2 rotating to the outside of the box body 1 to open (such as Figure 3 In the embodiment shown in the curved arrow in the figure, the first slider 715 is driven by the box body 1 and the traction mechanism to slide in the direction close to the first hinge 4, and the first slider 715 drives the second slider 709 to slide in the direction away from the first hinge 4 through the connecting member, thereby driving the door panel 21 to slide in the direction away from the first hinge 4, thereby avoiding interference between the door panel 21 and obstacles outside. Similarly, when the box door 2 rotates to one side of the box body 1 to close, the active sliding door mechanism 7 drives the door panel 21 to slide in the direction close to the first hinge 4, thereby avoiding interference between the door panel 21 and obstacles after closing.

[0085] Meanwhile, during the sliding process of the door panel 21, the third slider 913 of the driven sliding door mechanism 9 can slide along with the door panel 21 to support and assist the sliding of the door panel 21. In addition, the third sliders 913 of all the driven sliding door mechanisms 9 are connected by the first connecting rod 11, making the sliding synchronization of the connected sliders better, and thus making the sliding of the door panel 21 more stable.

[0086] For the door body assembly according to the embodiment of the present application, a sliding door device is provided on the box door 2. The sliding door device includes a driving sliding door mechanism 7, and the driving sliding door mechanism 7 is respectively connected to the box door 2 and the door panel 21. During the process of the box door 2 rotating relative to the box body 1 to open or close, it drives the door panel 21 to slide in the width direction of the box door 2, so that the door panel 21 can avoid obstacles such as side walls and objects during the closing or opening process of the box door 2. At the same time, by providing the 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. In addition, the third sliders 913 of all the driven sliding door mechanisms 9 are connected by the first connecting rod 11, making the sliding synchronization of the connected sliders better, and thus making the sliding of the door panel 21 more stable.

[0087] It can be understood that if the sliding door device has the beneficial effects of the above embodiment, the door body assembly correspondingly has the beneficial effects of the above embodiment. The specific implementation manner can refer to the above embodiment, and details are not described in this application again.

[0088] In an embodiment of the present application, as Figure 4 and Figure 5 shown, the traction mechanism includes a traction rod 702, a first rotating shaft fixing seat 713, and a second rotating shaft fixing seat 701. The first rotating shaft fixing seat 713 is connected to the first slider 715, the second rotating shaft fixing seat 701 is used to be connected to the box body 1, one end of the traction rod 702 is rotatably connected to the first rotating shaft fixing seat 713, and the other end of the traction rod 702 is rotatably connected to the second rotating shaft fixing seat 701.

[0089] In this embodiment, by respectively fixing the first rotating shaft fixing seat 713 and the second rotating shaft fixing seat 701 on the first slider 715 and the box body 1, and connecting them by the traction rod 702 between the first rotating shaft fixing seat 713 and the second rotating shaft fixing seat 701, the distance between the first slider 715 and the second rotating shaft fixing seat 701 is always kept unchanged. When the box door 2 rotates relative to the box body 1, the angle between the box body 1 and the box door 2 changes. Thus, the first slider 715 is tractioned through the transmission connection of the traction rod 702, the first rotating shaft fixing seat 713, and the second rotating shaft fixing seat 701, so that the first slider 715 slides on the base and drives the second slider 709 to slide to realize the movement of the door panel 21 relative to the box door 2.

[0090] In another embodiment of the present application, as Figure 1 andFigure 2 As shown in Figure 2 , a refrigeration device is provided, including: a box body 1 and a door body assembly as provided in any of the above embodiments. Among them, the box body 1 forms a storage space, and the box door 2 is rotatably connected to the box body 1 and is adapted to open or close the storage space.

[0091] In this embodiment, the door body assembly includes: a box door 2, a door panel 21, and a sliding door device. The sliding door device includes a main sliding door mechanism 7 and at least two driven sliding door mechanisms 9. The main sliding door mechanism 7 is disposed on the box door 2 and is configured to drive the door panel 21 to move relative to the width direction of the box door 2 during the opening or closing process of the box door 2. The driven sliding door mechanisms 9 can assist the sliding of the door panel 21.

[0092] The third sliders 913 of all the driven sliding door mechanisms 9 are connected by a first connecting rod 11, so that the sliding synchronization of the connected sliders is better, and thus the sliding of the door panel 21 is more stable.

[0093] By providing the door panel 21 on the box door 2, when the refrigeration device is an inlaid type and is disposed in a groove-shaped space or between two cabinet bodies, the door panel 21 can be set flush with the side wall of the groove or the cabinet bodies on both sides, so as to reduce the gap between the refrigeration device and the adjacent wall or cabinet body, making it more beautiful.

[0094] Meanwhile, when the box door 2 rotates, the main sliding door mechanism 7 can drive the door panel 21 to move relative to the box door 2 during the rotation of the box door 2 to move as far as possible away from obstacles such as the wall or cabinet body on the side of the box body 1 of the side door, so as to avoid these obstacles blocking the door panel 21 and affecting the rotation of the box door 2, resulting in the box door 2 being unable to be normally opened or closed.

[0095] The combination of the box door 2 and the door panel 21 enables the refrigeration device to avoid interference between the door panel 21 and surrounding objects when opening and closing, greatly improving the usability. Especially in a narrow kitchen environment, this design advantage is more obvious. In addition, the setting of the sliders and guide rails in the main sliding door mechanism 7, and the connection of the third sliders 913 of all the driven sliding door mechanisms 9 by the first connecting rod 11 enable the door panel 21 to move smoothly during the opening and closing processes, improving the service life and stability of the refrigerator.

[0096] It can be understood that if the door body assembly has the beneficial effects of the above embodiments, then the refrigeration device correspondingly has the beneficial effects of the above embodiments, and its specific implementation manners can refer to the above embodiments, and will not be elaborated in this application.

[0097] It can be understood that there can be multiple storage spaces.

[0098] It is understandable that multiple storage spaces can be arranged arbitrarily, such as arranged vertically, horizontally, etc. Multiple storage spaces can set storage conditions according to storage needs. For example, some storage spaces are set as refrigerating chambers, and another part of the storage spaces are set as freezing chambers.

[0099] As Figure 2 shown, an application scenario based on the above embodiment is as follows: The refrigeration device can be installed in a trough-shaped structure in the middle of a cabinet body. A door panel 21 is arranged on the outer side of the door 2 of the box body 1 of the refrigeration device. The material and color of the door panel 21 can be designed to be similar to or the same as the material color of the outer wall of the cabinet. When the door 2 is closed, the door panel 21 is flush with the outer wall of the cabinet at the opening edge of the trough-shaped structure and fits as closely as possible to the opening of the trough-shaped structure, so that the door panel 21 and the outer wall of the cabinet can maintain visual consistency and have a smaller gap, which is more beautiful.

[0100] When the door 2 rotates outward to open, the active sliding door mechanism 7 drives the door panel 21 to slide in a direction away from the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall on the side close to the first hinge 4, resulting in the door 2 being unable to open to a larger angle. When the door 2 rotates to close, the active sliding door mechanism 7 drives the door panel 21 to slide in a 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, resulting in the door 2 being unable to close completely and affecting the refrigeration preservation effect in the storage space. And when the door 2 is completely closed, the door panel 21 can return to a state flush with the cabinet body again.

[0101] In an embodiment of the present application, the box body 1 has a first storage space and a second storage space. There are two door body assemblies, namely a first door body assembly and a second door body assembly. The door 2 of the first door body assembly is rotatably connected to the box body 1 to open or close the first storage space, and the door 2 of the second door body assembly is rotatably connected to the box body 1 to open or close the second storage space.

[0102] In this embodiment, by providing a first storage space and a second storage space on the box body 1, the items to be stored are stored separately according to needs. The first storage space and the second storage space are respectively provided with a first door body assembly and a second door body assembly, so that when the doors 2 of the first door body assembly and the second door body assembly are rotated to open and close, the corresponding door panels 21 can slide relative to the door 2 to avoid obstacles.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered within the scope of the claims of the present invention.
