[0049] In an embedded furniture, a refrigeration device may be embedded in a cabinet. Among them, a door body 20 of the refrigeration device is rotatably connected to a box body 10 of the refrigeration device. The door body 20 of the refrigeration device can be used to cover an accommodation space inside the box 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 5 describe the sliding door mechanism of the refrigeration device of the present application.

[0052] The sliding door mechanism of a refrigeration device according to an embodiment of the present application includes a mounting plate 100, a connecting rod 200, a first slider 300, a second slider 400, and a link 500; the mounting plate is adapted to be mounted to the door body 10 (hereinafter simply referred to as the door body 20) of the refrigeration device, and the middle of the connecting rod 200 is rotatably connected to the mounting plate 100; both the first slider 300 and the second slider 400 are slidably connected to the mounting plate 100, the first slider 300 is rotatably connected to the first end of the connecting rod 200, the second slider 400 is rotatably connected to the second end of the connecting rod 200, the moving directions of the first slider 300 and the second slider 400 are opposite, and the second slider 400 is adapted to be mounted to the decorative plate; one end of the link 500 is rotatably connected to the first slider 300, and the other end is adapted to be rotatably connected to the cabinet 10. During the process of the door body 20 rotating and opening relative to the cabinet 10, the link 500 is adapted to rotate and drive the first slider 300 to slide, so that the second slider 400 moves in a direction away from the opening side of the door body 20.

[0053] For the sliding door mechanism of the refrigeration device according to an embodiment of the present application, when the decorative plate 30 is pulled open by the user to open the door, the door body 20 rotates relative to the cabinet 10, the door body 20 drives the link 500 to rotate, the link 500 drives the first end of the connecting rod 200 and the first slider 300 to move along the preset track, and drives the second end of the connecting rod 200 and the second slider 400 to move in the opposite direction under the drive of the connecting rod 200, so as to realize the relative movement between the decorative plate 30 and the door body 20, ensure that the decorative plate 30 connected by the rope can be normally closed, avoid the interference between the decorative plate 30 and the door body 20, and thus improve the user experience.

[0054] It can be understood that when the door body 20 is pushed by an external force (such as the user's hand), the door body 20 transmits the force to the first slider 300 through the link 500, and then drives the operation of the sliding door mechanism of the entire refrigeration device. The design of the link 500 cleverly converts the rotational movement of the door body 20 into the sliding movement of the slider, realizing the efficient transmission of power. During the process of the door body 20 rotating and opening relative to the cabinet 10, due to the rotation of the link 500 and the sliding of the first slider 300, the second end of the connecting rod 200 will drive the second slider 400 to move in a direction away from the opening side of the door body 20. This design of relative movement effectively avoids the interference between the decorative plate 30 and the door body 20 and ensures the smooth operation of the sliding door mechanism of the refrigeration device.

[0055] According to an embodiment of the present application, a first guiding groove 210 is formed at the first end of the connecting rod 200, a first guiding post 310 is provided on the first slider 300, and the first guiding post 310 is slidably connected to the first guiding groove 210; a second guiding groove 220 is formed at the second end of the connecting rod 200, a second guiding post 410 is provided on the second slider 400, and the second guiding post 410 is slidably connected to the second guiding groove 220.

[0056] It can be understood that the connecting rod 200 is rotatably connected to the mounting plate 100. During the opening and closing of the door body 20 relative to the cabinet 10, the movement of the connecting rod 200 is actually a rotational movement. By respectively providing a first guiding groove 210 and a second guiding groove 220 at the first end and the second end of the connecting rod 200, the rotational movement of the connecting rod 200 can be converted into a linear movement of the first slider 300 and the second slider 400 moving along a preset track.

[0057] Certainly, a first guiding post 310 can also be provided at the first end of the connecting rod 200, a first guiding groove 210 is provided on the first slider 300, and a second guiding post 410 is provided at the second end of the connecting rod 200, and a second guiding groove 220 is provided on the second slider 400.

[0058] According to an embodiment of the present application, the distance from the first guiding post 310 to the rotation center of the connecting rod 200 is less than the distance from the second guiding post 410 to the rotation center of the connecting rod 200.

[0059] It can be understood that since the first guiding post 310 is closer to the rotation center while the second guiding post 410 is farther away, when the door body 20 drives the first slider 300 (and the first guiding post 310) to move through the connecting rod 500, this asymmetric lever effect will cause a greater displacement of the second end of the connecting rod 200 (and the second slider 400 and the second guiding post 410), which helps to achieve a larger sliding amplitude within a limited space, thereby optimizing the opening and closing process of the sliding door mechanism of the refrigeration equipment.

[0060] According to an embodiment of the present application, the mounting plate 100 is provided with a first sliding rail 110 and a second sliding rail 120 that are parallel to each other. The first slider 300 is slidably connected to the first sliding rail 110, and the second slider 400 is slidably connected to the second sliding rail 120.

[0061] It can be understood that the first sliding rail 110 and the second sliding rail 120 are parallel to each other, ensuring the displacement stability between the decorative plate 30 and the door body 20. When the door body 20 is pushed, the first slider 300 moves along the first sliding rail 110, thereby driving the connecting rod 200 and the sliding door mechanism of the entire refrigeration equipment to move. Similarly, the second slider 400 is also slidably connected to the second sliding rail 120 through the sliding components at its bottom. The mutually parallel first sliding rail 110 and second sliding rail 120 provide stable support and guidance for the sliders, reducing the shaking and offset of the sliders during the sliding process.

[0062] It should be noted that the first sliding rail 110 and the second sliding rail 120 on the mounting plate 100 not only provide a sliding path for the first slider 300 and the second slider 400, but also enhance the structural strength of the sliding door mechanism of the entire refrigeration equipment.

[0063] According to an embodiment of the present application, the first slide rail 110 and the second slide rail 120 are respectively installed at two ends of the mounting plate 100, and the first slide rail 110 and the second slide rail 120 are arranged at intervals along the height direction of the mounting plate 100.

[0064] It can be understood that the first slide rail 110 and the second slide rail 120 are arranged at intervals along the height direction of the mounting plate 100. This design enables the two sliders to maintain a certain vertical distance difference during the sliding process, which helps to reduce the interference phenomenon of the sliding door mechanism of the refrigeration equipment during the opening and closing processes and improves the overall running smoothness.

[0065] According to an embodiment of the present application, the first slide rail 110 is installed with balls 600. During the sliding process of the first slider 300 along the first slide rail 110, the balls 600 are adapted to roll along the surface of the first slider 300.

[0066] It can be understood that the main function of the balls 600 is to reduce the direct contact area between the first slider 300 and the first slide rail 110, thereby significantly reducing the frictional resistance. The balls 600 can roll freely and form contact with the surface of the first slider 300. When the first slider 300 starts to slide under the action of an external force, the balls 600 will roll accordingly and provide low-resistance sliding support for the first slider 300.

[0067] According to an embodiment of the present application, the second slide rail 120 is installed with balls 600. During the sliding process of the second slider 400 along the second slide rail 120, the balls 600 are adapted to roll along the surface of the second slider 400.

[0068] Similarly, when the second slider 400 starts to slide under the action of an external force, the balls 600 will roll accordingly and provide low-resistance sliding support for the second slider 400.

[0069] According to an embodiment of the present application, the number of the balls 600 is multiple, and the multiple balls 600 are arranged along the extending direction of the first slide rail 110 or the second slide rail 120.

[0070] The multiple balls 600 are distributed evenly or unevenly along the extending direction of the slide rail. This distribution method can ensure that there are enough balls 600 to provide rolling support throughout the sliding process of the slider, thereby reducing the sliding resistance and maintaining the smoothness of the sliding.

[0071] The specific number and distribution density of the balls 600 can be adjusted according to the length of the slide rail, the weight of the slider, and the required sliding performance. For example, in the case of a longer slide rail or a heavier slider, the number and density of the balls 600 can be appropriately increased to improve the support effect.

[0072] According to an embodiment of the present application, the sliding door mechanism of the refrigeration device further includes a mounting base 700, and the mounting base 700 is used to be mounted on the box body 10. One end of the connecting rod 500 away from the first slider 300 is rotatably connected to the mounting base 700.

[0073] It can be understood that when installing the mounting base 700, only need to firmly mount the mounting base 700 on the box body 10 of the refrigeration device, and then connect components such as the connecting rod 500 to the mounting base 700 and the first slider 300 in sequence. To ensure the firmness and stability of the connection, fasteners such as bolts and nuts can be used to fix the mounting base 700 on the box body 10, and appropriate positioning structures and anti-loosening devices can be set.

[0074] One end of the connecting rod 500 away from the first slider 300 is rotatably mounted on the mounting base 700. The mounting base 700, as the support point of the connecting rod 500, can effectively disperse and bear various forces and torques generated during the opening and closing of the sliding door, thereby avoiding structural damage or deformation caused by stress concentration.

[0075] The door assembly of the refrigeration device according to the second aspect embodiment of the present application includes a door body 20, the sliding door mechanism of the refrigeration device described above, and a decorative panel 30. The mounting plate 100 is mounted on the door body 20; the decorative panel 30 is connected to the second slider 400 to slide relative to the door body 20.

[0076] According to the sliding door mechanism of the refrigeration device of the embodiment of the present application, when the decorative panel 30 is pulled open by the user to open the door, the door body 20 rotates relative to the box body 10, the door body 20 drives the connecting rod 500 to rotate, the connecting rod 500 drives the first end of the connecting rod 200 and the first slider 300 to move along the preset track, and drives the second end of the connecting rod 200 and the second slider 400 to move in the opposite direction under the drive of the connecting rod 200, so as to realize the relative movement between the decorative panel 30 and the door body 20, ensure that the decorative panel 30 connected by the connecting rope can be normally closed, avoid interference between the decorative panel 30 and the door body 20, and thus improve the user experience.

[0077] It should be noted that since the refrigeration device of the present application includes the sliding door mechanism of the refrigeration device described above, it has all the technical effects of the sliding door mechanism of the refrigeration device described above, which will not be elaborated here.

[0078] The refrigeration device according to the third aspect embodiment of the present application includes a box body 10 and the door assembly of the refrigeration device described above. 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.

[0079] It can be understood that the door assembly of the refrigeration device is arranged on the box body 10 through a rotating mechanism (such as a hinge, a rotating shaft, etc.). By rotating, the accommodating space can be opened or closed, which is convenient for users to store and retrieve items. When rotating, the decorative plate 30 and the door body 20 can have relative displacement, avoiding interference in the opening and closing of the door assembly of the refrigeration device and greatly improving the user experience.

[0080] 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.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the present application, rather than limiting 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.
