[0051] In an embedded furniture, a refrigeration device can be embedded in a cabinet. Among them, the door body 20 of the refrigeration device is rotatably connected to the cabinet body 10 of the refrigeration device. The door body 20 of the refrigeration device can be used to cover the accommodation space inside the cabinet body 10, and the 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.

[0052] 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 during the opening process of the door of the refrigeration device, it is prone to interference with the side wall of the cabinet and affects the use experience.

[0053] The following will be combined with Figures 1 to 4 Describe the sliding door mechanism of the refrigeration device of the present application.

[0054] For the sliding door mechanism of the refrigeration device proposed according to the embodiments of the present application, please refer to Figure 1 and Figure 2, the sliding door mechanism of the refrigeration device includes a bottom plate 100, a first slider 200, a second slider 300, a piston assembly 400, and a connecting rod 500. The bottom plate 100 is adapted to be mounted to the door body 20 of the refrigeration device; both the first slider 200 and the second slider 300 are slidably disposed on the bottom plate 100, and the second slider 300 is adapted to be mounted to the decorative plate 30; the piston assembly 400 includes a first end and a second end disposed opposite to each other, the first end is connected to the first slider 200, the second end is connected to the second slider 300, and the moving directions of the first end and the second end are opposite; one end of the connecting rod 500 is rotatably connected to the first slider 200, and the other end is adapted to be rotatably mounted to the box body 10 of the refrigeration device. During the door opening process, the connecting rod 500 is adapted to rotate to drive the first slider 200 to slide, and drive the second slider 300 to move in the opposite direction relative to the first slider 200.

[0055] For the sliding door mechanism of the refrigeration device according to the embodiment of the present application, when the user pulls it open to open the door, the door body 20 of the refrigeration device rotates relative to the box body 10 of the refrigeration device. The door body 20 drives the connecting rod 500 to rotate, and drives the first slider 200 to move. When the first slider 200 moves along the set direction of the bottom plate 100, the second slider 300 moves in the opposite direction of the first slider 200 under the action of the piston assembly 400, so as to realize the relative movement between the decorative plate 30 and the door body 20, ensure that the decorative plate 30 can be normally closed, avoid the interference between the decorative plate 30 and the door body 20, and thus improve the user experience.

[0056] It can be understood that the bottom plate 100 provides a stable sliding track for the sliding of the first slider 200 and the second slider 300. During the door opening process, when the connecting rod 500 is subjected to the pulling force of the rotation of the door body 20, the first slider 200 will slide along the bottom plate 100. This sliding motion is transmitted to the second slider 300 through the piston assembly 400, realizing the relative movement between the two, and further realizing the change of the relative position between the decorative plate 30 and the door body 20.

[0057] The piston assembly 400 realizes the relative movement between the first slider 200 and the second slider 300 through the movement between the internal piston cylinder and the piston rod.

[0058] One end of the connecting rod 500 is rotatably connected to the first slider 200, and the other end is mounted on the box body 10. During the door opening process, the connecting rod 500 is subjected to the pulling force of the rotation of the door body 20, driving the first slider 200 to slide along the bottom plate 100, thereby triggering the movement of the entire piston assembly 400.

[0059] According to an embodiment of the present application, the piston assembly 400 includes a first piston cylinder 410, a second piston cylinder 420, a first piston rod 430, and a second piston rod 440. The first piston cylinder 410 is disposed at the first end, and the second piston cylinder 420 is disposed at the second end. The first piston rod 430 is connected to the first slider 200 and is slidably connected to the first piston cylinder 410. The second piston rod 440 is connected to the second slider 300, and the moving directions of the first piston rod 430 and the second piston rod 440 are opposite. The second piston rod 440 is slidably connected to the second piston cylinder 420.

[0060] It can be understood that the first piston cylinder 410 and the second piston cylinder 420 are respectively disposed at both ends of the piston assembly 400, providing a sliding space and a sealed environment for the first piston rod 430 and the second piston rod 440, and ensuring the stability and reliability of the piston rod during movement.

[0061] The first piston rod 430 is connected to the first slider 200, while the second piston rod 440 is connected to the second slider 300. The moving directions of the first piston rod 430 and the second piston rod 440 are opposite, enabling the piston assembly 400 to directly drive the two sliders to perform relative movement.

[0062] When the connecting rod 500 is subjected to the pulling force of the rotation of the door body 20, it drives the first slider 200 to slide along the bottom plate 100. This sliding movement is transmitted to the first piston cylinder 410 through the first piston rod 430, pushing the medium (such as gas or liquid) in the piston cylinder to flow towards the second piston cylinder 420. At the same time, due to the opposite moving directions of the first piston rod 430 and the second piston rod 440, the medium in the second piston cylinder 420 is compressed or the second piston rod 440 is pushed to move in the opposite direction, thereby driving the second slider 300 to slide. Through the way of force transmission by the piston assembly 400 medium, the piston assembly 400 can smoothly and efficiently achieve the relative movement of the two sliders.

[0063] It should be noted that the sizes and specifications of the first piston cylinder 410 and the second piston cylinder 420 can be the same to ensure that the moving distances of the first slider 200 and the second slider 300 are the same. Of course, the sizes and specifications of the first piston cylinder 410 and the second piston cylinder 420 can also be different. By using the first piston cylinder 410 and the second piston cylinder 420 with different sizes and specifications, the moving distances of the second slider 300 and the first slider 200 can be adjusted to be different.

[0064] According to an embodiment of the present application, the first piston cylinder 410 and the second piston cylinder 420 are arranged side by side at one end of the bottom plate 100. It can be understood that arranging the piston cylinders side by side at one end of the bottom plate 100 can significantly reduce the occupied space of the sliding door mechanism of the refrigeration device in the horizontal direction, making the entire mechanism more compact.

[0065] According to an embodiment of the present application, the piston assembly 400 further includes a connecting elbow 450, and the connecting elbow 450 communicates with the first piston cylinder 410 and the second piston cylinder 420. It can be understood that the connecting elbow 450 allows the medium (such as gas or liquid) between the first piston cylinder 410 and the second piston cylinder 420 to flow. When one side piston rod moves, it will push or pull the piston rod on the other side through the medium to move in the opposite direction. This enables the two piston cylinders to be arranged side by side in the horizontal direction without the need for additional space to install other connecting mechanisms. This further enhances the structural compactness of the sliding door mechanism of the refrigeration device and saves installation space.

[0066] According to an embodiment of the present application, the first slider 200 is provided with a threaded hole, and the first piston rod 430 is threadedly connected to the threaded hole. By rotating the first piston rod 430 to make it fit tightly with the threaded hole, the stable connection between the first piston rod 430 and the first slider 200 is ensured. This connection method can resist large tensile and compressive forces and maintain the stable operation of the sliding door mechanism of the refrigeration device.

[0067] It can be understood that since the threaded connection has adjustability, the relative position between the first piston rod 430 and the first slider 200 can be adjusted as needed, thereby adjusting the movement stroke of the first piston rod 430.

[0068] According to an embodiment of the present application, the second slider 300 is provided with a threaded hole, and the second piston rod 440 is threadedly connected to the threaded hole. By rotating the second piston rod 440 to make it fit tightly with the threaded hole, the stable connection between the second piston rod 440 and the second slider 300 is ensured. This connection method can resist large tensile and compressive forces and maintain the stable operation of the sliding door mechanism of the refrigeration device.

[0069] It can be understood that since the threaded connection has adjustability, the relative position between the second piston rod 440 and the second slider 300 can be adjusted as needed, thereby adjusting the movement stroke of the second piston rod 440.

[0070] According to an embodiment of the present application, the bottom plate 100 includes a first slide rail 110 and a second slide rail 120. The first slide rail 110 and the second slide rail 120 are arranged on opposite sides of the bottom plate 100. The first slider 200 is slidably connected to the first slide rail 110, and the second slider 300 is slidably connected to the second slide rail 120.

[0071] It can be understood that the first slide rail 110 provides stable guidance for the first slider 200, and the second slide rail 120 provides stable guidance for the second slider 300. The first slide rail 110 and the second slide rail 120 ensure that the first slider 200 and the second slider 300 can maintain linear motion during the sliding process, reducing deviation and shaking. By directly arranging the first slide rail 110 and the second slide rail 120 on opposite sides of the bottom plate 100, the occupied space of the sliding door mechanism of the refrigeration device in the vertical direction can be further reduced.

[0072] The first slide rail 110 can be arranged on the front side of the bottom plate 100, and the second slide rail 120 can be arranged on the rear side of the bottom plate 100. It should be noted that the "front" and "rear" here are used to describe the relative relationship between the first slide rail 110 and the second slide rail 120, and are not specific limitations on this application.

[0073] According to an embodiment of the present application, the first slide rail 110 is formed with a first limiting groove 130, and the first slider 200 is snap-connected and slidably arranged in the first limiting groove 130.

[0074] It can be understood that the first limiting groove 130 ensures that the first slider 200 always remains on a predetermined track during the sliding process, which helps to reduce the deviation and shaking of the first slider 200 during the sliding process, and improves the stability and reliability of the sliding door mechanism of the refrigeration device.

[0075] According to an embodiment of the present application, the second slide rail 120 is formed with a second limiting groove 140, and the second slider 300 is snap-connected and slidably arranged in the second limiting groove 140.

[0076] It can be understood that the second limiting groove 140 ensures that the second slider 300 always remains on a predetermined track during the sliding process, which helps to reduce the deviation and shaking of the second slider 300 during the sliding process, and improves the stability and reliability of the sliding door mechanism of the refrigeration device.

[0077] According to an embodiment of the present application, the sliding door mechanism of the refrigeration device further includes a mounting seat 600, the mounting seat 600 is used for mounting to the box body 10 of the refrigeration device, and one end of the connecting rod 500 away from the first slider 200 is rotatably connected to the mounting seat 600.

[0078] It can be understood that the mounting base 600 provides a stable support platform for the sliding door mechanism of the refrigeration device, enabling the entire mechanism to be firmly mounted on the cabinet 10 of the refrigeration device. When installing the mounting base 600, it is only necessary to firmly mount the mounting base 600 on the cabinet 10 of the refrigeration device, and then sequentially connect components such as the connecting rod 500 to the mounting base 600 and the first slider 200. To ensure the firmness and stability of the connection, fasteners such as bolts and nuts can be used to fix the mounting base 600 on the cabinet 10, and appropriate positioning structures and anti-loosening devices can be provided.

[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 panel 30, and the above-mentioned sliding door mechanism of the refrigeration device. The bottom plate 100 is connected to the door body 20, the second slider 300 is connected to the decorative panel 30, and the decorative panel 30 is adapted to move relative to the door body 20 through the sliding door mechanism of the refrigeration device.

[0080] As before, the sliding door mechanism of the refrigeration device includes components such as a bottom plate 100, a first slide rail 110, a first slider 200, a second slide rail 120, a second slider 300, and a connecting rod 500. When the decorative panel 30 is pulled open by the user to open the door, the door body 20 of the refrigeration device rotates relative to the cabinet 10 of the refrigeration device. The door body 20 drives the connecting rod 500 to rotate and drives the first slider 200 to move. When the first slider 200 moves along the set direction of the bottom plate 100, the second slider 300 moves in the opposite direction of the first slider 200 under the action of the piston assembly 400, thereby realizing the relative movement between the decorative panel 30 and the door body 20, ensuring that the decorative panel 30 can be normally closed, avoiding interference between the decorative panel 30 and the door body 20, and thus improving the user experience.

[0081] It should be noted that since the door assembly of the refrigeration device of the present 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.

[0082] The refrigeration device according to the embodiment of the third aspect of the present application includes a cabinet 10, a door body 20, and the above-mentioned sliding door mechanism of the refrigeration device. An accommodation space is formed inside the cabinet 10; the door body 20 is rotatably connected to the cabinet 10 for covering the accommodation space; the bottom plate 100 of the above-mentioned sliding door mechanism of the refrigeration device is connected to the door body 20.

[0083] A closed accommodation space is formed inside the cabinet 10 for storing items that need to be refrigerated or frozen. The cabinet 10 can be made of heat-insulating materials to maintain the stability of the internal temperature and energy efficiency. The door body 20 is used to cover the accommodation space of the cabinet 10 to prevent cold air from leaking and at the same time protect the internal items from external pollution. When items need to be taken or placed, the user can access the accommodation space inside the cabinet 10 by opening the door body 20.

[0084] As described above, the sliding door mechanism of the refrigeration device includes components such as a bottom plate 100, a first slide rail 110, a first slider 200, a second slide rail 120, a second slider 300, and a connecting rod 500. When the second slider 300 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, the relative sliding between the decorative panel 30 and the door body 20 of the refrigeration device can be realized, ensuring that the decorative panel 30 can be normally closed and avoiding interference between the decorative panel 30 and the door body 20, thereby improving the user experience.

[0085] 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.

[0086] 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.
