In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0041] In an embedded furniture, a refrigeration device can be embedded in a cabinet. Among them, the door of the refrigeration device is rotatably connected to the cabinet of the refrigeration device. The door of the refrigeration device can be used to cover the accommodation space inside the cabinet, and a decorative panel 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.

[0042] However, when the door of the refrigeration device is opened, the decorative panel is prone to interference and collision with the side wall of the cabinet, resulting in a poor user experience of the embedded refrigerator. Therefore, the present application proposes a sliding door mechanism and a door assembly for 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 user experience.

[0043] The following will be combined with Figures 1 to 8 to describe the door assembly of the present application.

[0044] The door assembly according to the embodiment of the first aspect of the present application, please refer to Figures 1 to 9 , including: a door body, a decorative panel, a first elastic sheet 9, a second elastic sheet 10 and a sliding door mechanism. The door body is rotatably connected to the box body of the refrigeration device and is adapted to open or close the accommodation space inside the box body; the decorative panel is slidably arranged on the outer side of the door body; the first elastic sheet 9 and the second elastic sheet 10 which are arranged in an interleaved manner are fixedly connected to the box body, and the included angle between the first elastic sheet 9 and the second elastic sheet 10 is a first included angle; the sliding door mechanism includes a guide wheel assembly and a rope 5. The guide wheel assembly is adapted to be installed on the door body. The first end of the rope 5 branches into two branches, one of which is fixed to the first elastic sheet 9 and the other is fixed to the second elastic sheet 10. The second end of the rope 5 is adapted to sequentially bypass the guide wheel assembly and be connected to the decorative panel; during the door opening process, the second end of the rope 5 pulls the decorative panel to slide along the width direction of the door body, and the first end of the rope 5 pulls the first elastic sheet 9 and the second elastic sheet 10 to reduce the first included angle, and the first elastic sheet 9 and the second elastic sheet 10 generate elastic restoring forces.

[0045] According to the sliding door mechanism of the embodiment of the present application, when the door body is opened, the door body rotates relative to the box body. Through the guide wheel assembly, the second end of the rope 5 can drive the decorative panel to slide relative to the door body along the width direction of the box body, so that the decorative panel can avoid obstacles such as side walls and objects during the closing or opening process of the door body, and prevent the decorative panel from interfering with the obstacles and affecting the rotation of the door body, so as to meet the usage requirements of users in different scenarios. The first elastic sheet 9 and the second elastic sheet 10 can generate elastic restoring forces, so that when the door is closed, the decorative panel can have a tendency to reset, which is convenient for the decorative panel to reset and thus combine with the furniture decoration style.

[0046] Through the combination of the sliding door mechanism, the first elastic sheet 9 and the second elastic sheet 10, the opening and closing processes of the door body are made smoother and more natural, and at the same time, the decorative panel has the functions of sliding and resetting. It effectively solves the problem that the traditional door body may interfere with obstacles due to space limitations during the opening process, and improves the user experience.

[0047] According to an embodiment of the present application, the door body includes a first door body and a second door body, and the second door body and the first door body are arranged on the front side of the box body in a manner of opening towards each other; the decorative panel includes a first decorative panel and a second decorative panel. The first decorative panel is correspondingly arranged on the front side of the first door body, and the second decorative panel is correspondingly arranged on the front side of the second door body. The first door body and the second door body are respectively provided with a sliding door mechanism, and the two sliding door mechanisms are symmetrically arranged with respect to the dividing line between the first door body and the second door body.

[0048] It can be understood that the first door body and the second door body are arranged on the front side of the box body in a manner of opening towards each other. Specifically, the first door body can be the left door of the refrigeration device, and the second door body can be the right door of the refrigeration device. The first door body is rotatably connected to the left side wall of the box body, and the second door body is rotatably connected to the right side wall of the box body. Of course, the first door body and the second door body can also be the right door and the left door of the refrigeration device, which will not be elaborated here.

[0049] It should be noted that opening towards each other can be understood as that the first door body can be opened alone, or can be opened together with the second door body, and the second door body can also be opened alone.

[0050] It should be noted that the front side of the box body refers to the side closer to the user when the user is using the refrigeration device and stands in front of the refrigeration device. The side closer to the user is the front side of the box body, and the side farther from the user is the rear side of the box body.

[0051] It can be understood that the two sliding door mechanisms are symmetrically arranged with respect to the boundary line between the first door body and the second door body. During the door opening process, the decorative panel located on the first door body can move along the direction away from the rotating side of the first door body, and the decorative panel located on the second door body can also move along the direction away from the rotating side of the first door body, avoiding interference between the two decorative panels.

[0052] According to an embodiment of the present application, the first elastic sheet 9 and the second elastic sheet 10 are staggered to form a butterfly structure. The first ends of the first elastic sheet 9 and the second elastic sheet 10 are connected to the rope 5 of one of the sliding door mechanisms, and the second ends of the first elastic sheet 9 and the second elastic sheet 10 are connected to the rope 5 of the other sliding door mechanism.

[0053] The first elastic sheet 9 and the second elastic sheet 10 are arranged in an alternating manner to jointly form a butterfly structure similar to butterfly wings. This structure is not only beautiful but also has a certain stability and elasticity, and can generate corresponding deformations when subjected to external forces.

[0054] At both ends of the butterfly structure, that is, the first ends and the second ends of the first elastic sheet 9 and the second elastic sheet 10, are respectively connected to the ropes 5 of the two sliding door mechanisms. This connection method forms a dynamic linkage relationship between the two sliding door mechanisms. When one of the sliding door mechanisms moves, through the transmission of the rope 5 and the elastic sheet, the other sliding door mechanism can be driven to perform corresponding movements.

[0055] In one embodiment, as Figure 1 is a traction structure with left - right symmetry for the sliding door mechanism. Between the two sliding door mechanisms, two first elastic sheets 9 and second elastic sheets 10 form a deformable fan blade (vertical pressure spring, horizontal tension spring) connection, and can be independently retracted and closed left and right.

[0056] As Figure 2, when the right door is opened, the right traction structure drives the sliding door, and ф decreases. At the same time, affected by the horizontal spring tension, the Ω angle slightly opens, and the transmission force slightly moves the left door panel towards the hinge side. Similarly, when the left door is opened, as Figure 3 , the left traction structure drives the sliding door, and ф decreases. At the same time, affected by the horizontal spring tension, the Ω angle slightly opens, and the transmission force slightly moves the left door panel towards the hinge side.

[0057] as Figure 4 , when the left and right doors are opened simultaneously, the left and right butterfly plates are respectively stressed and contracted, and ф and Ω decrease simultaneously. The butterfly plates move separately and do not affect each other. When closing the door, the spring exerts force, and ф and Ω increase simultaneously for reset.

[0058] Thus, when two sliding door mechanisms are applied to a double - door refrigerator, the sliding door function can achieve stable force transmission in the scenarios of opening the left door and the right door separately and opening them simultaneously.

[0059] According to an embodiment of the present application, the guide wheel assembly includes a first guide wheel 2 and a second guide wheel 3 arranged side by side. The second end of the rope 5 is adapted to sequentially bypass the first guide wheel 2 and the second guide wheel 3 and connect to the decorative panel. The section of the rope 5 from the bifurcation of the rope 5 to the first guide wheel 2 is perpendicular to the connection line of the first guide wheel 2 and the second guide wheel 3.

[0060] It can be understood that the rope 5 can smoothly transmit force between the first guide wheel 2 and the second guide wheel 3, thereby realizing the sliding of the decorative panel. The first guide wheel 2 is responsible for guiding the direction of the first end of the rope 5, ensuring that the first end of the rope 5 and the section of the rope 5 from the rope 5 to the first guide wheel 2 are perpendicular to the connection line of the first guide wheel 2 and the second guide wheel 3. The second guide wheel 3 is responsible for guiding the winding angle of the rope 5, so that a certain angle difference can be formed during the winding process of the rope 5, thereby better adapting to the movement track of the sliding door mechanism, and improving the stability and durability of the entire sliding door mechanism.

[0061] According to an embodiment of the present application, at least one of the first guide wheel 2 and the second guide wheel 3 is provided with a guide groove 6, and the rope 5 is slidably arranged in the guide groove 6. The guide groove 6 ensures that the rope 5 can maintain a stable path during the transmission process. The rope 5 slides in the guide groove 6, and the sliding path is more accurate, which can more effectively convert the rotational movement of the door body into the translational movement of the decorative panel, improving the transmission efficiency of the entire mechanism.

[0062] According to an embodiment of the present application, the guide wheel assembly further includes a guide wheel frame 4. The guide wheel frame 4 is adapted to be installed on the door body. The guide wheel frame 4 is formed with a first mounting portion 7 and a second mounting portion 8 that are oppositely arranged. The first guide wheel 2 is installed on the first mounting portion 7, and the second guide wheel 3 is installed on the second mounting portion 8. The guide wheel frame 4 provides stable support for the first guide wheel 2 and the second guide wheel 3. The first guide wheel 2 and the second guide wheel 3 can be easily installed on the first mounting portion 7 and the second mounting portion 8, and fixing the guide wheel frame 4 to the door body can improve the structural strength of the entire sliding door mechanism.

[0063] According to an embodiment of the present application, the first guide wheel 2 is rotatably installed on the first mounting portion 7; and / or, the second guide wheel 3 is rotatably installed on the second mounting portion 8. It can be understood that the rotational installation of the first guide wheel 2 and the second guide wheel 3 allows them to rotate freely under the traction of the rope 5, thereby ensuring that the rope 5 can pass smoothly through the guide wheels for smooth transmission. The contact between them and the rope 5 is mainly rolling contact rather than sliding contact, reducing friction and resistance, improving the transmission efficiency, and extending their service life.

[0064] According to an embodiment of the present application, the rope 5 is an elastic rope 5. The elastic rope 5 has good elasticity and stretchability. When subjected to an external force, the elastic rope 5 can elongate or shorten to a certain extent and return to its original length after the external force disappears.

[0065] Due to the stretchability of the elastic rope 5, the elastic rope 5 can automatically adjust the tension and length according to the motion state of the sliding door mechanism. This self-adaptive adjustment function helps to maintain the balance and stability of the sliding door mechanism during movement, preventing deviation or jamming caused by changes in external forces.

[0066] Of course, the rope 5 of the present application can be made of an alloy, such as a steel wire rope, or can be made of a synthetic fiber material with high strength, wear resistance, and corrosion resistance, such as a nylon rope or a polyester fiber rope, to ensure its durability and reliability during use.

[0067] According to an embodiment of the present application, the sliding door mechanism further includes a fixing member 1. The fixing member 1 is used to be installed on the box body, and the first end of the rope 5 is fixed to the fixing member 1. The fixing member 1 serves as the fixing point of the first end of the rope 5. It is firmly installed on the box body, providing a stable support foundation for the entire sliding door mechanism. This stability ensures that the rope 5 will not fail due to loosening or falling off of the fixing point during transmission, thereby ensuring the normal operation of the sliding door mechanism.

[0068] In one embodiment, please refer to Figures 5 to 9, the sliding door mechanism includes a guide wheel assembly and a rope 5. The guide wheel assembly is adapted to be installed on the door body. The guide wheel assembly includes a first guide wheel 2 and a second guide wheel 3 arranged side by side; a rope 5, the first end of the rope 5 is adapted to be fixed to the box body, and the second end of the rope 5 is adapted to sequentially bypass the first guide wheel 2 and the second guide wheel 3 and connect to the decorative panel. During the door opening process, the guide wheel assembly moves with the door body, the first end of the rope 5 is fixed, and the second end of the rope 5 drives the decorative panel to translate along the width direction of the door body.

[0069] For the sliding door mechanism according to the embodiment of the present application, when the door body is opened, the door body rotates relative to the box body. Through the guide wheel assembly, the second end of the rope 5 can drive the decorative panel to slide relative to the door body along the width direction of the box body, so that the decorative panel can avoid obstacles such as side walls and objects during the closing or opening process of the door body, and prevent the decorative panel from interfering with the obstacles and affecting the rotation of the door body, so as to meet the usage requirements of users in different scenarios.

[0070] It can be understood that the rope 5 can smoothly transmit force between the first guide wheel 2 and the second guide wheel 3, so as to realize the sliding of the decorative panel. The first guide wheel 2 is responsible for guiding the direction of the first end of the rope 5, ensuring that the first end of the rope 5 and the rope segment of the rope 5 to the first guide wheel 2 are perpendicular to the connection line of the first guide wheel 2 and the second guide wheel 3. The second guide wheel 3 is responsible for guiding the winding angle of the rope 5, so that a certain angle difference can be formed during the winding process of the rope 5, so as to better adapt to the movement track of the sliding door mechanism, thereby improving the stability and durability of the entire sliding door mechanism.

[0071] In one embodiment, the fixing plate 1 is fixedly connected to the middle of the beam of the box body; the fixing plate 1 is fixedly connected to the first end of the rope 5; the first guide wheel 2 and the second guide wheel 3 are strongly fixed by a guide wheel frame 4 to form a pulley group, and the pulley group is fixedly connected to the refrigerator door body; one end of the rope 5 is connected to the fixing plate 1, and then sequentially winds around the fixed pulleys 3 and 4 counterclockwise, and the other end is finally connected to the cabinet door. As Figure 5 .

[0072] In the normal use scenario, when the door body is pulled open by the user to open the door, the decorative panel and the door body perform an external rotational movement relative to the box body. Since one end of the rope 5 is fixed in the middle of the box body, and the door body rotates around the corner of the box body, during the door opening process, as the distance between the door body and the box body increases, the rope 5 will be pulled up. Through the transmission of the first guide wheel 2 and the second guide wheel 3, the pulling force is finally transmitted to the decorative panel, thereby pulling the decorative panel to perform a translational movement along the door body. As Figure 6 , Figure 7 , where S in the figure is the length of the rope 5 being pulled.

[0073] Similarly, when the door body is closed by the user, the decorative panel and the door body perform an inward rotation movement relative to the box body. Since one end of the rope 5 is fixed in the middle of the box body, and the door body rotates around the corner of the box body, during the closing process, as the distance between the door body and the box body decreases, the rope 5 will slacken and retract. Through the transmission of the first guide pulley 2 and the second guide pulley 3, the return force will ultimately be transmitted to the decorative panel, thereby translating the decorative panel along the door body for reset. As Figure 8 , Figure 9 .

[0074] Thus, when the door body and the decorative panel are rotated and opened relative to the box body at the same time, the decorative panel and the door body will perform relative translational displacement. In the usage scenario of the right-opening refrigerator introduced in this embodiment, when opening the door, the decorative panel moves to the left relative to the door body, thus avoiding the interference between the decorative panel and the cabinet body on the hinge side. The same applies to the left-opening refrigerator. By using the multi-pulley movement, the stability of the rope 5 transmission can be improved, and the comfort of opening the door can be enhanced.

[0075] The refrigerator according to the second aspect embodiment of the present application includes a box body and the above-mentioned door assembly. The box body forms an accommodation space, and the door assembly is rotatably arranged on the box body to open or close the accommodation space.

[0076] It can be understood that the door assembly can be arranged on the box body through a rotating mechanism (such as a hinge, a rotating shaft, etc.). By rotating the door assembly, the accommodation space can be opened or closed, which is convenient for users to store and retrieve items. When rotating, the decorative panel and the door body can have relative displacement, avoiding the interference of the opening and closing of the door body assembly, and greatly improving the user experience.

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

[0078] 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 within the scope of the claims of the present application.
