[0049] In an embedded furniture, a refrigeration device can be embedded in a cabinet. Among them, a door body 20 of the refrigeration device is rotatably connected to a cabinet body 10 of the refrigeration device. The door body 20 of the refrigeration device can be used to cover an accommodation space inside the cabinet body 10, and a decorative panel 30 can be used to cover the cabinet body of the cabinet, so as to combine the outer surface of the cabinet with the home decoration style.

[0050] However, as the door body 20 of the refrigeration device is opened, the decorative panel 30 is prone to interference and collision with the side wall of the cabinet, resulting in a poor use experience of the embedded refrigerator. Therefore, the present application proposes a door assembly of a refrigeration device to solve the defect that the refrigeration device is prone to interference with the side wall of the cabinet during the door opening process, affecting the use experience.

[0051] The following will be combined with Figures 1 to 3 Describe the sliding door mechanism of the refrigeration device, the door assembly of the refrigeration device, and the refrigeration device of the present application.

[0052] According to the sliding door mechanism of the refrigeration device (hereinafter simply referred to as the sliding door mechanism) proposed in the first aspect embodiment of the present application, please refer to Figure 1 and Figure 2, the sliding door mechanism includes a mounting plate 100, a slider 200, and a connecting rod assembly 300. The mounting plate 100 is adapted to be mounted to the door body 20 of the refrigeration device; the slider 200 is slidably disposed on the mounting plate 100, and the slider 200 is adapted to be mounted to the decorative plate 30; one end of the connecting rod assembly 300 is rotatably connected to the slider 200, and the other end is adapted to be rotatably connected to the cabinet 10. The door body 20 of the refrigeration device is adapted to be rotatably connected to the cabinet 10; during the opening process of the door body 20 of the refrigeration device relative to the cabinet 10, the connecting rod assembly 300 is adapted to rotate to push the slider 200 to move in a direction away from the rotation side of the door body 20 of the refrigeration device.

[0053] According to the sliding door mechanism of the embodiment of the present application, when the user pulls the door body 20 of the refrigeration device to rotate relative to the cabinet 10, the mounting plate 100 rotates along with the rotation of the door body 20 of the refrigeration device, and drives the connecting rod assembly 300 to rotate, so as to drive the slider 200 to slide on the mounting plate 100, thereby realizing the relative movement between the door body 20 of the refrigeration device and the decorative plate 30, avoiding the interference between the door body 20 of the refrigeration device and the decorative plate 30 during the rotation process, and thus improving the user experience.

[0054] Through the linkage relationship between the connecting rod assembly 300, the slider 200, and the mounting plate 100, it is ensured that during the rotation and opening process of the door body 20 of the refrigeration device, the decorative plate 30 (connected through the slider 200) can automatically and smoothly move to a position where it will not interfere with the door body 20 of the refrigeration device. This design greatly improves the user experience, eliminating the need for the user to manually adjust or worry about collisions between the door bodies 20.

[0055] According to an embodiment of the present application, the connecting rod assembly 300 includes a first connecting rod 310 and a second connecting rod 320. One end of the first connecting rod 310 is rotatably connected to the cabinet 10; one end of the second connecting rod 320 is rotatably connected to the end of the first connecting rod 310 away from the cabinet 10, and the other end is rotatably connected to the slider 200.

[0056] The combination of the first connecting rod 310 and the second connecting rod 320 makes the mechanism more flexible in transmitting motion. During the door opening process, the angle between the first connecting rod 310 and the second connecting rod 320 changes, thereby driving the slider 200 to move. The double-connecting-rod structure provides more support points and constraint conditions, which helps to enhance the stability of the sliding door mechanism during the movement process.

[0057] The first connecting rod 310 and the second connecting rod 320 can be made of high-strength and corrosion-resistant materials. For example, stainless steel connecting rods, aluminum alloy connecting rods, or carbon fiber connecting rods, etc. In addition, high-quality bearings or spherical plain bearings can be used as the rotating connectors between the first connecting rod 310 and the second connecting rod 320.

[0058] According to an embodiment of the present application, one end of the first link 310 is provided with a first mounting post 301. The end of the first mounting post 301 is provided with a threaded portion, and a first nut 330 is installed on the threaded portion. The second link 320 is rotatably connected to the first mounting post 301, and the second link 320 is disposed between the first link 310 and the first nut 330.

[0059] It can be understood that during installation, only need to align the second link 320 with the first mounting post 301 and place it well, and then tighten the first nut 330. This installation method is simple and fast, without the need for complex tools or steps. The second link 320 is clamped between the first link 310 and the first nut 330. Through the connection between the threaded portion and the nut thread, the connection between the second link 320 and the first link 310 is very stable.

[0060] It should be noted that the threaded connection has the characteristics of being easy to install and disassemble. When it is necessary to replace or repair the rotating shaft 311, only need to loosen the first nut 330 to easily separate the first link 310 and the second link 320, which greatly reduces the maintenance cost and time.

[0061] According to an embodiment of the present application, the slider 200 is provided with a second mounting post 201. The end of the second mounting post 201 is provided with a threaded portion, and a second nut 340 is installed on the threaded portion. The second link 320 is rotatably connected to the second mounting post 201, and the second link 320 is disposed between the slider 200 and the second nut 340.

[0062] During installation, only need to align the second link 320 with the second mounting post 201 and place it well, and then tighten the second nut 340. This installation method is simple and fast, without the need for complex tools or steps. The second link 320 is clamped between the slider 200 and the second nut 340. Through the connection between the threaded portion and the nut thread, the connection between the second link 320 and the slider 200 is very stable.

[0063] It should be noted that the threaded connection has the characteristics of being easy to install and disassemble. When it is necessary to replace or repair the rotating shaft 311, only need to loosen the second nut 340 to easily separate the slider 200 and the second link 320, which greatly reduces the maintenance cost and time.

[0064] According to an embodiment of the present application, the sliding door mechanism further includes a hinge seat 400. The hinge seat 400 is provided with a mounting portion for mounting to the box body 10 and a rotating portion rotatably connected to the door body 20 of the refrigeration device. The first link 310 is rotatably connected to the hinge seat 400.

[0065] It is understandable that the hinge seat 400 provides a stable support platform for the sliding door mechanism, so that the entire mechanism can be firmly installed on the box body 10 of the refrigeration equipment. When installing the hinge seat 400, it is only necessary to firmly install the hinge seat 400 on the box body 10 of the refrigeration equipment, and then connect the connecting rod assembly 300 and other components to the hinge seat 400 and the slider 200 in sequence. In order to ensure the firmness and stability of the connection, the hinge seat 400 can be fixed to the box body 10 with fasteners such as bolts and nuts, and appropriate positioning structures and anti-loosening devices can be set.

[0066] According to an embodiment of the present application, the hinge seat 400 is provided with a mounting hole, a rotating shaft 311 is installed at one end of the first connecting rod 310, the rotating shaft 311 passes through the mounting hole, and the rotating shaft 311 is clearance-matched with the mounting hole.

[0067] It can be understood that the rotational connection is achieved by passing the rotating shaft 311 through the mounting hole, and the clearance fit between the rotating shaft 311 and the mounting hole enables the rotating shaft 311 to rotate smoothly in the mounting hole.

[0068] According to an embodiment of the present application, a threaded section is provided at the end of the rotating shaft 311 , and the threaded section is mounted on the hinge seat 400 through a third nut 350 , and the third nut 350 abuts against the hinge seat 400 .

[0069] It is understandable that a threaded section is provided at the end of the rotating shaft 311 so that the third nut 350 can be tightly screwed on the thread, thereby achieving a firm connection between the rotating shaft 311 and the hinge seat 400. This fastening method is more reliable than a simple clearance fit and can effectively prevent the rotating shaft 311 from loosening or falling off during rotation.

[0070] It should be noted that the threaded connection is easy to install and disassemble. When the rotating shaft 311 needs to be replaced or repaired, the rotating shaft 311 can be easily removed from the hinge base 400 by simply loosening the third nut 350, which greatly reduces maintenance costs and time.

[0071] According to an embodiment of the present application, the rotating shaft 311 is provided with a limiting portion 312 , and the limiting portion 312 is located between the first connecting rod 310 and the hinge seat 400 .

[0072] It is understandable that the limiting portion 312 can prevent the rotating shaft 311 from falling off from the hinge seat 400 when rotating or being acted upon by an external force. By limiting the movement range of the rotating shaft 311 in the axial direction, it is ensured that the rotating shaft 311 is always maintained at a predetermined connection position.

[0073] The upper end of the rotating shaft 311 can be fixedly installed through a nut. The nut is screwed onto the threaded section of the rotating shaft 311 to firmly fix the rotating shaft 311 on the hinge seat 400. The lower end of the rotating shaft 311 is limited by a limiting portion 312. The design of the limiting portion 312 prevents the rotating shaft 311 from moving downward, thus keeping it in a predetermined connection position. This limiting method effectively prevents the risk of the rotating shaft 311 falling off due to external forces.

[0074] According to an embodiment of the present application, the sliding door mechanism further includes a hanging ear 500, and the hanging ear 500 is provided with a mounting hole for connecting with the decorative plate 30; the slider 200 is provided with a plugging slot 210, and the hanging ear 500 is plugged into the plugging slot 210.

[0075] It can be understood that the hanging ear 500 is used to transfer the weight and the forces received by the door body 20 to the slider 200, ensuring that the door body 20 can run smoothly during the sliding process. The hanging ear 500 also plays a role in positioning and fixing, preventing the door body 20 from shifting or shaking during the sliding process.

[0076] The plugging slot 210 is arranged on the slider 200, and its position and shape match those of the hanging ear 500 to ensure that the hanging ear 500 can be smoothly inserted and fixed in the plugging slot 210. The shape of the plugging slot 210 can be rectangular, circular or other geometric shapes, specifically depending on the shape and size of the hanging ear 500.

[0077] According to an embodiment of the present application, the mounting plate 100 is provided with a slide rail 110, the slide rail 110 is formed with a card slot 120, and the slider 200 is provided with a clamping portion 220, and the clamping portion 220 is adapted to be clamped in the card slot 120 and slide relative to the card slot 120.

[0078] It can be understood that the slide rail 110 arranged on the mounting plate 100 is the track for the slider 200 to slide. The slider 200 can be entirely located on the slide rail 110, or the slider 200 can be partially slidably connected to the slide rail 110, such as the clamping portion 220. The shape and size of the clamping portion 220 match those of the card slot 120 so as to be smoothly clamped into the card slot 120 and slide relative to it.

[0079] The door assembly of the refrigeration device according to the embodiment of the second aspect of the present application includes a door body 20, a decorative plate 20 and the above-mentioned sliding door mechanism of the refrigeration device. The mounting plate 100 of the sliding door mechanism of the refrigeration device is installed on the door body 20; the decorative plate 20 is connected to the slider 200 to slide relative to the door body 20.

[0080] It should be noted that the door body 20 mentioned in this application can be an independent component, connected to the door panel of the refrigeration device, or the door body 20 can also be integrally formed with the door panel of the refrigeration device. The decorative panel 20 mentioned in this application can also be an independent component, connected to the cabinet door. Of course, the decorative panel 20 can also be integrally formed with the cabinet door.

[0081] As mentioned above, the sliding door mechanism of the refrigeration device includes a mounting plate 100, a slider 200, and a connecting rod assembly 300. When the user pulls the door body 20 to rotate relative to the box body 10, the mounting plate 100 rotates along with the rotation of the door body 20, driving the connecting rod assembly 300 to rotate, so as to drive the slider 200 to slide on the mounting plate 100, thereby realizing the relative movement between the door body 20 and the decorative panel 20, avoiding interference between the door body 20 and the decorative panel 20 during the rotation process, and thus improving the user experience.

[0082] Through the linkage relationship between the connecting rod assembly 300, the slider 200, and the mounting plate 100, it is ensured that during the process of the door body 20 rotating and opening, the decorative panel 20 (connected through the slider 200) can automatically and smoothly move to a position where it will not interfere with the door body 20. This design greatly improves the user experience, eliminating the need for the user to manually adjust or worry about collisions between the door bodies 20.

[0083] It should be noted that since the door assembly of the refrigeration device in this application includes the above-mentioned sliding door mechanism of the refrigeration device, it has all the technical effects of the above-mentioned sliding door mechanism of the refrigeration device, which will not be elaborated here.

[0084] According to the refrigeration device of the third aspect embodiment of the present application, referring to Figure 3 , the refrigeration device includes a box body 10 and the above-mentioned door assembly of the refrigeration device. The box body 10 forms a receiving space, and the door assembly of the refrigeration device is rotatably arranged on the box body 10 to open or close the receiving space.

[0085] An enclosed receiving space is formed inside the box body 10 for storing items that need to be refrigerated or frozen. The box body 10 can be made of heat-insulating materials to maintain the stability of the internal temperature and energy efficiency. The door body 20 of the refrigeration device is used to cover the receiving space of the box body 10, preventing cold air from leaking and protecting the internal items from external pollution. When items need to be taken or placed, the user can access the receiving space inside the box body 10 by opening the door body 20 of the refrigeration device.

[0086] As described above, the sliding door mechanism of the refrigeration device includes a mounting plate 100, a slider 200, and a connecting rod assembly 300. When the slider 200 is connected to the decorative panel 30 of the built-in furniture (such as a cabinet), through the action of the sliding door mechanism of the refrigeration device, relative sliding between the decorative panel 30 and the door panel of the refrigeration device can be achieved, ensuring that the decorative panel 30 can be normally closed and avoiding interference between the decorative panel 30 and the door panel, thereby enhancing the user experience.

[0087] It should be noted that since the refrigeration device of the present application includes the above-mentioned door assembly of the refrigeration device, it has all the technical effects of the above-mentioned door assembly of the refrigeration device, which will not be elaborated here.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the present application, rather than to limit the present application. Although the present application 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 application do not depart from the spirit and scope of the technical solutions of the present application, and should all be covered by the scope of the claims of the present application.
