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.

[0044] In an embedded furniture, a refrigeration device can be embedded in a cabinet. Among them, a door body of the refrigeration device is rotatably connected to a box body of the refrigeration device. The door body of the refrigeration device can be used to cover an accommodation space inside the box body, 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.

[0045] 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.

[0046] The following combines Figures 1 to 8 to describe the sliding door mechanism of the present application.

[0047] According to the sliding door mechanism proposed in the first aspect embodiment of the present application, please refer to Figures 1 to 8 , the sliding door mechanism includes: a gear rod 3, a connecting rod 2, a first gear 4, a second gear 7, a first rack 5 and a second rack 6. One end of the connecting rod 2 is rotatably connected to the gear rod 3, and the other end is adapted to be rotatably connected to the box body. The first gear 4 and the second gear 7 are fixedly connected to the gear rod 3, and the first gear 4 and the second gear 7 are respectively arranged at different positions in the axial direction of the gear rod 3. The first rack 5 is drivingly connected to the first gear 4, and the first rack 5 is adapted to be mounted on the door body. The second rack 6 is drivingly connected to the second gear 7, and the second rack 6 is adapted to be mounted on the decorative panel. The gear rod 3 is arranged between the first rack 5 and the second rack 6. The first rack 5 and the second rack 6 are arranged staggeredly, and the tooth grooves of the first rack 5 and the second rack 6 face the gear rod 3. During the door opening process, the connecting rod 2 rotates and drives the gear rod 3 to rotate. The gear rod 3 drives the first gear 4 and the second gear 7 to rotate, so that the second rack 6 moves in the opposite direction relative to the first rack 5, and the second rack 6 is adapted to slide along the width direction of the door body.

[0048] 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. The connecting rod 2 rotates and drives the gear rod 3 to rotate, driving the first gear 4 and the second gear 7 connected to the gear rod 3 to rotate, so that the first rack 5 and the second rack 6 move relative to each other. The decorative panel connected to the second rack 6 can slide along the width direction of the door body relative to 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 use requirements of users in different scenarios.

[0049] It can be understood that when the user opens the door body, the door body rotates relative to the box body, and this movement is transmitted to the gear rod 3 through the connecting rod 2, causing it to rotate. The rotation of the gear rod 3 further drives the first gear 4 and the second gear 7 to rotate synchronously. However, due to their different positions on the gear rod 3, the first rack 5 and the second rack 6 driven by them respectively will generate relative movement. The first rack 5 is installed on the door body and moves together with the door body. The second rack 6 is connected to the decorative panel, and its movement direction is opposite to that of the first rack 5. This relative movement enables the decorative panel to slide along the width direction of the door body, thus avoiding possible obstacles.

[0050] In one embodiment, the fixing plate 1 is fixedly connected to the box body; the fixing plate 1 is connected to the connecting rod 2 by a bearing, and the connecting rod 2 can rotate freely within the plane of the fixing plate 1; the gear rod 3 is connected to the connecting rod 2 by a pin. When the connecting rod 2 rotates, the gear rod 3 can rotate by itself; the gear rod 3 is fixedly connected to the first gear 4 and the second gear 7, and the first gear 4 and the second gear 7 rotate together with the gear rod 3; the first gear 4 engages with the first rack 5 in a gear motion, and the second gear 7 engages with the second rack 6 in a gear motion; the first rack 5 and the second rack 6 are respectively fixedly connected to the door body and the decorative panel and are immovable. As Figure 1 。

[0051] In the normal use scenario, when the decorative panel door body is pulled open by the user, the decorative panel and the door body rotate outward relative to the cabinet box body. The first rack 5 and the second rack 6 will jointly hold the first gear 4 and the second gear 7, driving the gear rod 3 to rotate outward in space, thereby driving the connecting rod 2 to rotate outward around the fixing plate 1. At this time, affected by the movement of the connecting rod 2, the gear rod 3 will rotate clockwise by itself. The first gear 4 and the second gear 7 will also drive clockwise rotation. Driven by the engagement of the first gear 4 and the first rack 5, the first rack 5 and the second rack 6 move in opposite directions. Since the racks are fixed to the corresponding door body and decorative panel, we can consider that the door body and the decorative panel move in opposite directions. When taking the door body as the reference system, the decorative panel undergoes a multi-fold displacement movement towards the opening side relative to the door body, accelerating the translational speed of the decorative panel. As Figure 2 , Figure 3 。

[0052] Similarly, when the user closes the door, the decorative panel and the door body perform an inward rotational movement relative to the cabinet body. The first rack 5 and the second rack 6 will jointly engage with the first gear 4, and the second gear 7 drives the gear rod 3 to rotate inward in space, thereby driving the connecting rod 2 to rotate inward around the fixed plate 1. At this time, affected by the movement of the connecting rod 2, the gear rod 3 will perform a self-counterclockwise spin. The first gear 4 and the second gear 7 will also drive a counterclockwise spin. Driven by gear meshing, the first rack 5 and the second rack 6 perform relative direction movements. Since the racks are fixed to the corresponding door body and decorative panel, we can consider that the door body and the decorative panel perform relative direction movements. When taking the door body as the reference system, the decorative panel undergoes a multi-fold displacement movement towards the hinge side relative to the door body, accelerating the translational speed of the decorative panel. The multiple can be adjusted through the multi-gear coefficient ratio and customized according to needs, such as Figure 4 , Figure 5 .

[0053] Thus, when the door body and the decorative panel are simultaneously rotated and opened relative to the cabinet body, the decorative panel and the door body will perform relative translational displacements. What this solution describes is 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, thus 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 the multi-gear ratio movement, the relative movement between the decorative panel and the door body can be adjusted to adapt to more complex use scenarios.

[0054] According to an embodiment of the present application, the second gear 7 is larger than the first gear 4, or the module of the second gear 7 is larger than the module of the first gear 4. It can be understood that by making the second gear 7 larger than the first gear 4 (in terms of diameter or number of teeth), or by selecting the second gear 7 to have a larger module (the module determines the tooth pitch and size of the gear), the transmission ratio between the first gear 4 and the second gear 7 can be adjusted. Thus, the moving distance of the second rack 6 is greater, ensuring that during the door-opening process, the decorative panel can slide at a predetermined speed and distance.

[0055] According to an embodiment of the present application, the first gear 4 is integrally formed at the end of the gear rod 3, and the second gear 7 is provided with a third mounting hole 10, and the gear rod 3 is fixedly connected and passes through the third mounting hole 10.

[0056] The integrally formed design of the first gear 4 and the gear rod 3 means that the two are formed simultaneously during the manufacturing process without additional connecting parts or process steps. This design not only simplifies the manufacturing process but also improves the integrity and strength of the structure. Since the number of connecting parts is reduced, the risk of failure caused by loose or broken connections is also reduced.

[0057] The third mounting hole 10 provided on the second gear 7 is specifically designed to cooperate with the gear rod 3. This hole usually has an appropriate diameter and depth so that the gear rod 3 can penetrate and be firmly fixed thereto. The shape and position of the mounting hole should ensure that the gear rod 3 can maintain a stable transmission relationship after penetration.

[0058] The second gear 7 is fixedly connected to the gear rod 3 through the third mounting hole 10. This connection method can adopt various methods, such as key connection, pin connection, interference fit or threaded connection, etc.

[0059] According to an embodiment of the present application, the connecting rod 2 is provided with a first mounting hole 8, and the gear rod 3 is rotatably connected to the first mounting hole 8. When the connecting rod 2 rotates, the gear rod 3 rotates in the first mounting hole 8.

[0060] It can be understood that the outer contour of the gear rod 3 and the hole axis of the first mounting hole 8 are in fit. When the connecting rod 2 rotates, the gear rod 3 can freely rotate inside the first mounting hole 8. During the door opening process, the connecting rod 2 rotates in a direction away from the side where the door body rotates, driving the gear rod 3 to move along with the connecting rod 2. At the same time, the gear component meshes with the first rack 5 and the second rack 6. Since the gear rod 3 can freely rotate in the first mounting hole 8, the gear component can rotate smoothly.

[0061] According to an embodiment of the present application, it further includes a fixing plate 1. The connecting rod 2 is adapted to be fixedly connected to the box body through the fixing plate 1, and the connecting rod 2 is rotatably connected to the fixing plate 1. It can be understood that the fixing plate 1 provides a stable support point for the connecting rod 2, enabling it to be more firmly connected to the box body. The fixing plate 1 can provide various mounting methods such as bolt connection, welding connection or snap connection. For example, the fixing plate 1 can be provided with mounting holes and connecting pieces, making the installation process more simple and fast. In addition, the fixing plate 1 can also be used as a reference for adjusting the position of the connecting rod 2, improving the installation accuracy and precision.

[0062] According to an embodiment of the present application, it further includes a bearing provided at the connection between the connecting rod 2 and the fixing plate 1. It can be understood that the bearing can reduce the direct wear between the connecting rod 2 and the fixing plate 1. Under the same driving force, the connecting rod 2 can rotate more smoothly, thereby accelerating the response speed and operation efficiency of the sliding door mechanism.

[0063] According to an embodiment of the present application, on one side of the first rack 5 facing away from the tooth groove, a first mounting protrusion 11 is provided, and the first mounting protrusion 11 is used to be mounted in a corresponding first mounting groove on the door body. It can be understood that the first mounting protrusion 11 matches the first mounting groove on the door body, and through their mutual embedding, a firm connection between the first rack 5 and the door body is achieved. Moreover, the design of the first mounting protrusion 11 and the first mounting groove makes the installation of the first rack 5 simple and fast. During the installation process, only need to align the first mounting protrusion 11 with the first mounting groove on the door body, and then gently push it in to achieve fixation. This design reduces the installation steps and required tools, and reduces the installation cost and time.

[0064] According to an embodiment of the present application, on one side of the second rack 6 facing away from the tooth groove, a second mounting protrusion 12 is provided, and the second mounting protrusion 12 is used to be mounted in a corresponding second mounting groove on the decorative panel. It can be understood that the second mounting protrusion 12 matches the second mounting groove on the door body, and through their mutual embedding, a firm connection between the second rack 6 and the door body is achieved. Moreover, the design of the second mounting protrusion 12 and the second mounting groove makes the installation of the second rack 6 simple and fast. During the installation process, only need to align the second mounting protrusion 12 with the second mounting groove on the door body, and then gently push it in to achieve fixation. This design reduces the installation steps and required tools, and reduces the installation cost and time.

[0065] For the door assembly according to the second aspect embodiment of the present application, please refer to Figures 6 to 8 , the door assembly 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 first rack 5 of the sliding door mechanism is connected to the door body; the second rack 6 of the sliding door mechanism is connected to the decorative panel, and the decorative panel slides along the width direction of the door body through the sliding door mechanism.

[0066] 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 pipelines of the refrigeration device, making the front appearance of the refrigeration device more tidy and beautiful.

[0067] 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, 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.

[0068] 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.

[0069] 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.

[0070] It should be noted that the front side of the box body means that when the user is using the refrigeration device, the user stands in front of the refrigeration device, the side close to the user is the front side of the box body, and the side far from the user is the rear side of the box body.

[0071] It can be understood that the two sliding door mechanisms are symmetrically arranged with respect to the demarcation 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.

[0072] According to an embodiment of the present application, it includes a first magnetic member 13 and a second magnetic member 14. The first magnetic member 13 is rotatably connected to the middle of the connecting rod 2 of one of the sliding door mechanisms, and the second magnetic member 14 is rotatably connected to the middle of the connecting rod 2 of the other sliding door mechanism. The magnetic pole directions of the first magnetic member 13 and the second magnetic member 14 are opposite. When the first door body and the second door body are closed, as the connecting rod 2 rotates, the first magnetic member 13 and the second magnetic member 14 are magnetically attached, driving the connecting rod 2 to rotate, and the first decorative panel and the second decorative panel are reset.

[0073] It can be understood that the first magnetic member 13 is rotatably connected to the middle of the connecting rod 2 of one sliding door mechanism, while the second magnetic member 14 is rotatably connected to the middle of the connecting rod 2 of the other sliding door mechanism. The magnetic pole directions of these two magnetic members are opposite so as to generate a strong attractive force when they approach each other. When the user manually closes the first door body and the second door body, as the door bodies are gradually closed, the connecting rods 2 of the two sliding door mechanisms will also rotate accordingly.

[0074] During this process, the first magnetic member 13 and the second magnetic member 14 will gradually approach each other. When the first door body and the second door body are almost completely closed, the first magnetic member 13 and the second magnetic member 14 will attract each other due to the opposite magnetic poles and then undergo magnetic attachment. This magnetic attractive force will serve as an auxiliary force to help further drive the connecting rod 2 to rotate until it reaches the fully closed and reset state. At the same time, this also means that the first decorative panel and the second decorative panel will also be automatically brought back to their initial positions.

[0075] It can be understood that by introducing the magnetic member, the sliding door mechanism can obtain an additional magnetic auxiliary force during the closing process, so as to achieve automatic reset more smoothly and accurately, which can improve the user experience. The user only needs to gently push the door body, and the remaining reset work can be automatically completed by the magnetic member.

[0076] According to an embodiment of the present application, the first magnetic member 13 and the second magnetic member 14 are provided with mounting grooves 15, an installation post 16 is arranged inside the mounting groove 15, a second mounting hole 9 is provided in the middle of the connecting rod 2, the middle part of the connecting rod 2 is located in the mounting groove 15, and the second mounting hole 9 is rotatably connected to the installation post 16.

[0077] It can be understood that both the first magnetic member 13 and the second magnetic member 14 are provided with mounting grooves 15. The mounting groove 15 provides a rotating space for the connecting rod 2. An installation post 16 is arranged inside the mounting groove 15. The installation post 16 can be tightly inserted into the second mounting hole 9 of the connecting rod 2 and allows the connecting rod 2 to freely rotate on the installation post 16.

[0078] The refrigerator according to the third aspect embodiment of the present application includes a box body and the above-mentioned door assembly. The box body forms a containing space, and the door assembly is rotatably arranged on the box body to open or close the containing space.
