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.

[0040] In an embedded furniture, a refrigeration device can be embedded in a cabinet. Among them, the door body of the refrigeration device is rotatably connected to the cabinet body of the refrigeration device. The door body of the refrigeration device can be used to cover the accommodation space inside the cabinet body, and a decorative panel can be used to cover the cabinet body of the cabinet, so that the outer surface of the cabinet is combined with the home decoration style.

[0041] However, as the door body 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 use 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 use experience.

[0042] The following is combined with Figures 1 to 9 to describe the sliding door mechanism of the present application.

[0043] The sliding door mechanism according to the first aspect embodiment of the present application 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 cabinet 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.

[0044] 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 cabinet 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 cabinet 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 use requirements of users in different scenarios.

[0045] It can be understood that the rope 5 can smoothly transmit force between the first guide pulley 2 and the second guide pulley 3, thereby realizing the sliding of the decorative panel. The first guide pulley 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 pulley 2 are perpendicular to the connection line between the first guide pulley 2 and the second guide pulley 3. The second guide pulley 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.

[0046] 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 pulley 2 and the second guide pulley 3 are strongly fixed by the guide pulley 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 winds around the fixed pulleys 3 and 4 counterclockwise in turn, and the other end is finally connected to the cabinet door. As Figure 1 .

[0047] In the normal use scenario, when the door body is pulled open by the user, 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 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 pulley 2 and the second guide pulley 3, the pulling force will ultimately be transmitted to the decorative panel, thereby pulling the decorative panel to perform a translational movement along the door body. As Figure 2 , Figure 3 , where S in the figure is the length by which the rope 5 is pulled.

[0048] Similarly, when the door body is closed by the user, the decorative panel and the door body perform an internal 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 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 returning force will ultimately be transmitted to the decorative panel, thereby resetting the decorative panel to perform a translational movement along the door body. As Figure 4 , Figure 5 .

[0049] Thus, when the door body and the decorative panel are rotated open relative to the box body at the same time, the decorative panel and the door body will perform a relative translational displacement. This embodiment describes the use scenario of a right-opening refrigerator. When the door is opened, the decorative panel moves to the left relative to the door body, thereby avoiding the interference between the decorative panel and the cabinet body on the hinge side. The same applies to a left-opening refrigerator. By using multi-pulley movement, the stability of the rope 5 transmission can be improved, and the opening comfort can be enhanced.

[0050] 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 disposed in the guide groove 6. The guide groove 6 ensures that the rope 5 can maintain a stable path during transmission. The rope 5 slides in the guide groove 6, and the sliding path is more precise, 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.

[0051] 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 which 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 conveniently installed on the first mounting portion 7 and the second mounting portion 8, and by fixing the guide wheel frame 4 to the door body, the structural strength of the entire sliding door mechanism can be improved.

[0052] 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, thus 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.

[0053] 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.

[0054] 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 offset or jamming phenomena caused by changes in external forces.

[0055] 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.

[0056] According to an embodiment of the present application, the sliding door mechanism further includes a fixing member 1 for mounting to the box body, and the first end of the rope 5 is fixed to the fixing member 1. As the fixing point of the first end of the rope 5, the fixing member 1 is firmly mounted 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 detachment of the fixing point during the transmission process, thus ensuring the normal operation of the sliding door mechanism.

[0057] According to an embodiment of the present application, the distance between the first guide pulley 2 and the second guide pulley 3 is adjustable. By adjusting the distance between the first guide rope pulley and the second guide rope pulley, users can optimize the operating effect of the sliding door mechanism according to different installation conditions (such as door thickness, chute length, etc.). Appropriate distance adjustment helps to optimize the winding path and tension transmission mode of the rope 5, thereby improving the operating efficiency and stability of the sliding door mechanism. At the same time, reducing unnecessary friction and wear also helps to extend the service life of the sliding door mechanism.

[0058] Specifically, a sliding adjustment mechanism can be provided on the sliding frame to allow the second guide rope pulley to slide relative to the first guide rope pulley on the sliding frame within a certain range. An extensible connecting rod can also be used to connect the first guide rope pulley and the second guide rope pulley. The extensible connecting rod has an extensible function, and users can change the distance between the two guide rope pulleys by adjusting the length of the connecting rod.

[0059] Of course, in addition to the two methods exemplified above, other methods can also be used to adjust the distance between the first guide rope pulley and the second guide rope pulley.

[0060] According to an embodiment of the present application, one of the first guide pulley 2 and the second guide pulley 3 is a bearing, and the rope 5 is wound around the outer ring of the bearing. Due to the rolling contact characteristics of the bearing, the rope 5 can transmit force more smoothly during the winding process, reducing the energy loss caused by friction. This helps to improve the transmission efficiency of the sliding door mechanism, making the opening and closing actions of the door body faster and smoother.

[0061] The door assembly according to the second aspect embodiment of the present application is applied to a refrigeration device and includes: a door body, the above-mentioned sliding door mechanism, and a decorative panel. 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 guide pulley assembly of the sliding door mechanism is installed on the door body; the decorative panel is connected to the second end of the rope 5, and the decorative panel slides along the width direction of the door body through the sliding door mechanism.

[0062] The decorative panel can be integrated according to the overall decoration style of the refrigeration device and the cabinet. In addition, the decorative panel can also be used to hide the unsightly elements such as cables and pipes of the refrigeration device, making the front appearance of the refrigeration device cleaner and more beautiful.

[0063] The door assembly proposed according to an embodiment of the present application is shown in Figures 6 to 9 The door assembly includes 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 disposed outside the door body. The first elastic sheet 9 and the second elastic sheet 10 are fixedly connected to the box body in an alternating manner, 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 branch is fixed to the first elastic sheet 9, and the other branch is fixed to the second elastic sheet 10. The second end of the rope 5 is adapted to be sequentially wound around the guide wheel assembly and 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.

[0064] 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, preventing the decorative panel from interfering with the obstacles and affecting the rotation of the door body, 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, facilitating the reset of the decorative panel and thus combining the decorative panel with the furniture decoration style.

[0065] 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, improving the user experience.

[0066] According to an embodiment of the present application, the door body includes a first door body and a second door body. The second door body and the first door body are arranged on the front side of the box body in a way of opening towards each other. The decorative panel includes a first decorative panel and a second decorative panel. The first decorative panel is correspondingly disposed on the front side of the first door body, and the second decorative panel is correspondingly disposed on the front side of the second door body. The first door body and the second door body are respectively provided with sliding door mechanisms, 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] It can be understood that the two sliding door mechanisms are symmetrically arranged with respect to the dividing line between the first door body and the second door body. During the door opening process, the decorative panel on the first door body can move along the direction away from the rotating side of the first door body, and the decorative panel 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.

[0071] According to an embodiment of the present application, the first elastic piece 9 and the second elastic piece 10 are staggered to form a butterfly structure. The first ends of the first elastic piece 9 and the second elastic piece 10 are connected to the rope 5 of one of the sliding door mechanisms, and the second ends of the first elastic piece 9 and the second elastic piece 10 are connected to the rope 5 of the other sliding door mechanism.

[0072] The first elastic piece 9 and the second elastic piece 10 are arranged in a staggered manner to jointly form a butterfly structure similar to the wings of a butterfly. This structure is not only beautiful but also has a certain stability and elasticity, and can generate corresponding deformations when subjected to external forces.

[0073] At both ends of the butterfly structure, that is, the first ends and the second ends of the first elastic piece 9 and the second elastic piece 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 piece, the other sliding door mechanism can be driven to perform corresponding movements.

[0074] 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 be connected to the decorative panel. The rope segment from the bifurcation of the rope 5 to the first guide wheel 2 is perpendicular to the connection line between the first guide wheel 2 and the second guide wheel 3.

[0075] It can be understood that the rope 5 can smoothly transmit force between the first guide pulley 2 and the second guide pulley 3, thereby realizing the sliding of the decorative panel. The first guide pulley 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 pulley 2 are perpendicular to the connection line between the first guide pulley 2 and the second guide pulley 3. The second guide pulley 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.

[0076] In one embodiment, as Figure 6 is a traction structure with left-right symmetry for the sliding door mechanism. Between two sliding door mechanisms, two first elastic sheets 9 and a second elastic sheet 10 form a deformable fan blade (vertical compression spring, horizontal tension spring) connection, and can be independently retracted and closed left and right.

[0077] As Figure 7 , when the right door is opened, the right traction structure drives the sliding door, and ф becomes smaller. At the same time, affected by the horizontal spring tension, the Ω angle slightly expands, and the transmission force slightly moves the left door panel towards the hinge side. Similarly, when the left door is opened, as Figure 8 , the left traction structure drives the sliding door, and ф becomes smaller. At the same time, affected by the horizontal spring tension, the Ω angle slightly expands, and the transmission force slightly moves the left door panel towards the hinge side.

[0078] As Figure 9 , when the left and right doors are opened simultaneously, the left and right butterfly pieces are respectively stressed and contracted, ф and Ω become smaller simultaneously, and the butterfly pieces move separately without affecting each other. When closing the door, the spring exerts force, and ф and Ω become larger simultaneously for reset.

[0079] Thus, when two sliding door mechanisms are applied to a double-door refrigerator, stable force transmission of the sliding door function can be realized in the scenarios of opening the left door and the right door separately and opening them simultaneously.

[0080] The refrigerator according to the embodiment of the third aspect 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.

[0081] 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 interference during the opening and closing of the door body assembly, and greatly improving the user experience.

[0082] 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.

[0083] 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 within the scope of the claims of the present application.
