[0051] The following will describe Figures 1 to 6 the sliding door mechanism, door body assembly, and refrigeration device of the present application. The sliding door mechanism and door body assembly in the present application can be applied to household appliances, such as refrigerators. However, it should be understood that the door body assembly of the present application can also be applied to dishwashers, washing machines, or any other suitable devices. The refrigeration device in the present application is, for example, applied as a refrigerator. However, it should be understood that the refrigeration device of the present application can also be applied as a freezer or any other suitable device.

[0052] In one embodiment of the present application, as Figures 1 to 6 shown, the sliding door mechanism 1 is applied to a refrigeration device. The refrigeration device includes a door 2, a box body 4, and a door panel 3. The door 2 is rotatably connected to the box body 4 and is adapted to open or close the storage space of the box body 4. The door panel 3 is slidably disposed on the outer side of the door 2. The sliding door mechanism 1 includes a base 13, a traction member 9, a first sliding member 11, a second sliding member 12, and a connecting member 15. One side of the base 13 forms a first groove 131, and the other side forms a second groove 132. The first sliding member 11 is slidably disposed in the first groove 131. The second sliding member 12 is slidably disposed in the second groove 132 and is connected to the door panel 3. The two ends of the connecting member 15 are respectively connected to the first sliding member 11 and the second sliding member 12. The two ends of the traction member 9 are respectively rotatably connected to the box body 4 and the first sliding member 11. During the opening or closing process of the door 2, the box body 4 drives the first sliding member 11 to move in the first groove 131 through the traction member 9, and the first sliding member 11 drives the second sliding member 12 to move in the second groove 132 in the opposite direction through the connecting member 15, so as to drive the door panel 3 to move along the width direction of the door 2.

[0053] Specifically, the first groove 131 is located inside the base 13, providing a sliding space for the first sliding member 11. The second groove 132 is located outside the base 13, parallel or at an angle to the first groove 131, providing a sliding space for the second sliding member 12. The first sliding member 11 is slidably disposed on the first groove 131 and is used for driving connection with the box body 4. The second sliding member 12 is slidably disposed on the second groove 132 and is used for connection with the door panel 3. The connecting member 15 can be a connecting component such as a traction rope or a transmission belt. The two ends of the connecting member 15 are respectively connected to the first sliding member 11 and the second sliding member 12.

[0054] When the first sliding member 11 is driven to move on the first groove 131, since the two ends of the connecting member 15 are respectively fixed to the first sliding member 11 and the second sliding member 12, by reasonably setting the extending direction of the connecting member 15, the connecting member 15 will drive the second sliding member 12 to move in the opposite direction on the second groove 132. This characteristic of synchronous reverse movement enables the door panel 3 to slide relative to the width direction of the box body 4 when the first sliding member 11 is in driving connection with the box body 4 and the second sliding member 12 is connected to the door panel 3.

[0055] The sliding door mechanism 1 provided by the present utility model, by respectively disposing the first sliding member 11 and the second sliding member 12 on the first groove 131 and the second groove 132, and using the connecting member 15 to connect the first sliding member 11 and the second sliding member 12, enables the second sliding member 12 to be driven to move in the opposite direction when the first sliding member 11 moves. Thus, when the first sliding member 11 is in driving connection with the box body 4 and the second sliding member 12 is connected to the door panel 3, the sliding door mechanism 1 can be used to drive the door panel 3 to slide relative to the width direction of the box door 2, so that the door panel 3 can avoid obstacles such as side walls and objects during the closing or opening process of the box door 2, thereby meeting the usage requirements of users in different scenarios.

[0056] It should be noted that in practical applications, the designs of the first sliding member 11 and the second sliding member 12 can be flexible and variable to adapt to different working scenarios and performance requirements. They are not limited to specific shapes, sizes or materials, but can be customized and optimized according to specific needs.

[0057] From the perspective of materials, the first sliding member 11 and the second sliding member 12 can be made of materials with high wear resistance, low friction coefficient and good stability, such as metal alloys, engineering plastics or special lubricating materials. The selection of these materials aims to improve the durability of the sliding members, reduce wear and noise during the sliding process, and ensure the smoothness of sliding.

[0058] In some embodiments, such as Figures 3 to 6As shown, the first sliding member 11 includes a first rotating shaft 111 and a first pulley 112, and the second sliding member 12 includes a second rotating shaft 121 and a second pulley 122. The first rotating shaft 111 is connected to the first pulley 112, and the first pulley 112 is rotatably arranged in the first groove 131. The second rotating shaft 121 is connected to the second pulley 122, and the second pulley 122 is rotatably arranged in the second groove 132. The connecting member 15 is connected to the first rotating shaft 111 and the second rotating shaft 121.

[0059] In this embodiment, by adjusting the length or position of the first rotating shaft 111, the contact point of the first pulley 112 in the first groove 131 can be finely adjusted, thereby optimizing the sliding path and reducing friction and wear. At the same time, by adjusting the length or position of the second rotating shaft 121, the contact point of the second pulley 122 in the second groove 132 can be finely adjusted, thereby optimizing the sliding path and reducing friction and wear.

[0060] The adoption of the first pulley 112 and the second pulley 122 not only reduces the resistance during the sliding process, but also realizes a smoother sliding action through their rolling characteristics, improving the overall operation efficiency and stability of the sliding door mechanism. This design not only extends the service life of the sliding door mechanism, but also brings a more smooth and quiet door opening and closing experience to users.

[0061] In some embodiments, as Figures 3 to 6 shown, there are multiple first pulleys 112 and second pulleys 122. The first rotating shaft 111 passes through the multiple first pulleys 112, and the second rotating shaft 121 passes through the multiple second pulleys 122. First limiting notches for clamping the first pulley 112 are formed on both sides of the first groove 131, and the first pulleys 112 on both sides are respectively embedded in the first limiting notches on both sides. Second limiting notches for clamping the second pulley 122 are formed on both sides of the second groove 132, and the second pulleys 122 on both sides are respectively embedded in the second limiting notches on both sides.

[0062] Specifically, the first pulley 112 and the second pulley 122 are respectively connected in series through the first rotating shaft 111 and the second rotating shaft 121. This design not only enhances the stability of the sliding, but also disperses the load borne by a single pulley, thereby effectively extending the service life of the pulley. Multiple pulleys are in contact with the corresponding first groove 131 or second groove 132 at the same time, which can distribute the pressure during the sliding process more evenly, reduce the wear on a single contact point, and further improve the smoothness and durability of the sliding.

[0063] Secondly, on both sides of the first groove 131 and the second groove 132, a first limiting notch and a second limiting notch for clamping the pulley are respectively provided. This limiting design not only ensures the stability of the pulley during the sliding process, preventing the pulley from wobbling or shifting within the groove, but also provides an additional guiding function, enabling the pulley to slide smoothly along a predetermined path. The tight fit between the first limiting notch and the first pulley 112, and the tight fit between the second limiting notch and the second pulley 122, reduce the noise and vibration generated due to excessive gaps, further enhancing the user experience.

[0064] In addition, the design of multiple pulleys also makes the sliding door mechanism more flexible and adaptable when dealing with different loads and usage environments. For example, when it is necessary to carry a heavier door panel, the sliding performance can be optimized by increasing the number of pulleys or adjusting the pulley layout to ensure the stable operation of the sliding door mechanism.

[0065] In some embodiments, as Figures 3 to 6 shown, the connecting member 15 is a rope, and the connecting member 15 includes a first connecting member and a second connecting member. The first connecting member bypasses one end of the base 13, and both ends are respectively connected to one end of the first sliding member 11 and the second sliding member 12; the second connecting member bypasses the other end of the base 13, and both ends are respectively connected to the other end of the first sliding member 11 and the second sliding member 12.

[0066] Specifically, one end of the first connecting member is fixed at a predetermined position of the first sliding member 11, then bypasses a specific part of the base 13 (such as a pulley or a guiding device on the base), and finally connects to the corresponding position of the second sliding member 12. In this way, when the first sliding member 11 moves on the first groove 131, the first connecting member can smoothly transmit this movement and drive the second sliding member 12 to move in the opposite direction on the second groove 132.

[0067] Similarly, the second connecting member also bypasses the other end of the base 13, but the path is different from that of the first connecting member to ensure the balance and stability between the two sliding members. One end of the second connecting member is fixed at another predetermined position of the first sliding member 11 (opposite to the connection point of the first connecting member), bypasses the other side of the base 13, and finally connects to the other end of the second sliding member 12. This double-connecting member design not only enhances the reliability of the connection but also makes the entire sliding door mechanism operate more smoothly and steadily.

[0068] By adjusting the bypass path and the fixed point position of the first connecting member and the second connecting member on the base 13, the performance of the sliding door mechanism can be further optimized. For example, the tension of the rope can be adjusted to ensure the synchronism and consistency of the first sliding member 11 and the second sliding member 12 during the movement.

[0069] In some embodiments, as Figures 3 to 6As shown, the sliding door mechanism 1 further includes: a first fixed seat and a second fixed seat. The first fixed seat is connected to one end of the base 13 and is formed with a first limiting groove. Both ends of the first limiting groove are butted against one end of the first groove 131 and the second groove 132, and a part of the first connecting member is slidably disposed in the first limiting groove; the second fixed seat is connected to the other end of the base 13 and is formed with a second limiting groove. Both ends of the second limiting groove are butted against the other end of the first groove 131 and the second groove 132, and a part of the second connecting member is slidably disposed in the second limiting groove.

[0070] In this embodiment, the first fixed seat is connected to one end of the base 13, and the first limiting groove is butted against one end of the first groove 131 and the second groove 132, forming a smooth transition region. The first connecting member (i.e., a part of the rope) can freely slide in this limiting groove while being subject to certain constraints to ensure its movement along a predetermined path. This design not only reduces the friction and wear of the first connecting member during movement but also improves the operating efficiency and stability of the entire sliding door mechanism. Similarly, the second fixed seat is connected to the other end of the base 13 and forms a second limiting groove. The second limiting groove is butted against the other end of the first groove 131 and the second groove 132. The second connecting member (also a part of the rope) is slidably disposed in the second limiting groove and works in cooperation with the first connecting member to jointly drive the synchronous reverse movement of the first sliding member 11 and the second sliding member 12. The presence of the first limiting groove and the second limiting groove not only provides stable guidance for the connecting members but also limits the movement range of the connecting members through their structural characteristics.

[0071] Optionally, for the convenience of connection with external structures (such as the box door 2 or the box body frame), fixing holes are usually provided on the first fixed seat and / or the second fixed seat. The positions and numbers of these fixing holes are determined according to the connection methods and requirements of the external structures. The sliding door mechanism 1 further includes fasteners, which are used to pass through the fixing holes on the fixed seats to firmly fix the sliding door mechanism to the external structures. The fasteners can be fasteners in the form of bolts, screws, rivets, etc., and the specific selection depends on the actual application scenarios and connection requirements. During installation, the fasteners pass through the fixing holes and cooperate with the corresponding components (such as nuts, threaded holes, etc.) on the external structures to achieve a firm connection through tightening or riveting.

[0072] In some embodiments, as Figures 3 to 6 shown, rotatable support bearings can be provided in the first limiting groove and / or the second limiting groove as needed; a part of the first connecting member is pressed on the support bearings in the first limiting groove; and / or, a part of the second connecting member is pressed on the support bearings in the second limiting groove.

[0073] Specifically, when a support bearing is arranged in the first limiting groove, a part of the first connecting member (i.e., a part of the rope) is pressed on these support bearings. The rolling characteristics of the support bearings enable the first connecting member to pass through the first limiting groove more smoothly during the sliding process, reducing wear and noise caused by direct friction. Similarly, if support bearings are also arranged in the second limiting groove, the corresponding part of the second connecting member will also be pressed on these bearings, achieving a similar smooth sliding effect.

[0074] When selecting support bearings, factors such as their load-bearing capacity, wear resistance, and rolling resistance need to be considered to ensure that they can maintain stable performance during long-term use. In addition, the installation position and quantity of the bearings are also adjusted according to requirements. Generally, at least two are required to support the first connecting member and the second connecting member respectively. In actual applications, a reasonable layout is made according to the specific design and usage requirements of the sliding door mechanism to achieve the best sliding effect and support stability.

[0075] In summary, by arranging rotatable support bearings in the first limiting groove and / or the second limiting groove, the sliding door mechanism 1 in these embodiments has been significantly improved in terms of smoothness, durability, and overall performance.

[0076] In an embodiment of the present application, as Figures 3 to 6 shown, the sliding door mechanism 1 further includes a connecting shaft 14. One end of the connecting shaft 14 is connected to the second sliding member 12, and the other end of the connecting shaft 14 is connected to an external structure.

[0077] Specifically, both ends of the connecting shaft 14 are respectively connected to the second sliding member 12 and the door panel 3. When the first sliding member 11 moves under the driving force on the first groove 131, the connecting member 15 will drive the second sliding member 12 to move in the opposite direction on the second groove 132. Thus, the second sliding member 12 can drive the door panel 3 to move through the connecting shaft 14, enabling the door panel 3 to slide relative to the width direction of the box body 4.

[0078] In an embodiment of the present application, as Figure 4 shown, the traction member 9 includes a traction rod, a first rotating shaft fixing seat, and a second rotating shaft fixing seat. The first rotating shaft fixing seat is connected to the first sliding member 11, the second rotating shaft fixing seat is used to be connected to the box body 4, one end of the traction rod is rotatably connected to the first rotating shaft fixing seat, and the other end of the traction rod is rotatably connected to the second rotating shaft fixing seat.

[0079] In this embodiment, by fixing the first rotating shaft fixing seat and the second rotating shaft fixing seat to the first sliding member 11 and the box body 4 respectively, and connecting them through a traction rod between the first rotating shaft fixing seat and the second rotating shaft fixing seat, when the box door 2 rotates relative to the box body 4, the angle between the box body 4 and the box door 2 changes. Thus, the first sliding member 11 is tractioned through the transmission connection of the traction rod, the first rotating shaft fixing seat and the second rotating shaft fixing seat, so that the first sliding member 11 slides on the base 13, and drives the second sliding member 12 to slide to realize the movement of the door panel 3 relative to the box door 2.

[0080] In one embodiment of the present application, as Figures 1 to 6 shown, the door body assembly includes: a box door 2, a door panel 3 and a sliding door mechanism 1. The box door 2 is rotatably connected to the box body 4 and is adapted to open or close the storage space of the box body 4; the door panel 3 is slidably arranged outside the box door 2; the sliding door mechanism 1 is arranged on the box door 2, and the sliding door mechanism 1 includes a base 13, a traction member 9, a first sliding member 11, a second sliding member 12 and a connecting member 15. A first groove 131 is formed on one side of the base 13, and a second groove 132 is formed on the other side; the first sliding member 11 is slidably arranged in the first groove 131; the second sliding member 12 is slidably arranged in the second groove 132 and is connected to the door panel 3; both ends of the connecting member 15 are respectively connected to the first sliding member 11 and the second sliding member 12; both ends of the traction member 9 are respectively rotatably connected to the box body 4 and the first sliding member 11. During the opening or closing process of the box door 2, the box body 4 drives the first sliding member 11 to move in the first groove 131 through the traction member 9, and the first sliding member 11 drives the second sliding member 12 to move in the second groove 132 in the opposite direction through the connecting member 15, so as to drive the door panel 3 to move in the width direction of the box door 2.

[0081] Specifically, during the process of the box door 2 rotating and opening towards the outside of the box body 4 (as shown by the arc arrow in Figure 1 ), the sliding door mechanism 1 drives the door panel 3 to slide away from the hinge 5, so as to avoid interference between the door panel 3 and the external obstacles. During the process of the box door 2 rotating and closing towards one side of the box body 4, the sliding door mechanism 1 drives the door panel 3 to slide towards the hinge 5, so as to avoid interference between the door panel 3 and the obstacles after closing.

[0082] According to the door body assembly of the embodiment of the present application, the box door 2 is rotatably connected to the box body 4, the door panel 3 is slidably arranged outside the box door 2, and the sliding door mechanism 1 is arranged on the box door 2. The sliding door mechanism 1 connects the box door 2 and the door panel 3, so as to drive the door panel 3 to slide in the width direction relative to the box door 2 during the process of the box door 2 rotating and opening or closing relative to the box body 4, so that the door panel 3 can avoid obstacles such as side walls and objects during the closing or opening process of the box door 2, and avoid interference between the door panel 3 and the obstacles, which affects the rotation of the box door 2, so as to meet the use requirements of users in different scenarios.

[0083] In some embodiments, as Figure 1 and Figure 2 shown, the door assembly and the box body 4 are configured to be disposed in the installation space 8 formed between the first cabinet body 6 and the second cabinet body 7. An opening is provided on the outer side of the installation space 8. This design enables the door assembly and the box body 4 to be integrally embedded in the cabinet body. During the process that the box door 2 passes through the opening to control the opening or closing of the storage space, the sliding door mechanism 1 is configured to drive the door panel 3 to move a preset distance on the box door 2 in a direction away from or close to the hinge 5, so that the door panel 3 can avoid the side walls of the first cabinet body 6 and the second cabinet body 7.

[0084] During the process that the box door 2 passes through the opening to control the opening or closing of the storage space, the sliding door mechanism 1 is configured to drive the door panel 3 to move a preset distance on the box door 2 in a direction away from or close to the hinge 5. This design is mainly to avoid interference between the door panel 3 and the side walls of the first cabinet body 6 and the second cabinet body 7. Through the movement of the preset distance, the door panel 3 can be smoothly opened or closed without colliding or jamming with the side walls of the cabinet body.

[0085] For example, as Figure 1 and Figure 2 shown, during the process of opening the box door 2, the sliding door mechanism 1 drives the door panel 3 to move a preset distance along the box door 2 in a direction away from the hinge 5. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet body 7, so that the box door 2 can be fully opened, facilitating users to store and retrieve items.

[0086] Similarly, during the process of closing the box door 2, the sliding door mechanism 1 drives the door panel 3 to move a preset distance along the box door 2 in a direction close to the hinge 5. In this way, the door panel 3 can smoothly avoid the side wall of the first cabinet body 6, so that the box door 2 can be fully closed, maintaining the overall aesthetics and sealing performance.

[0087] This design not only improves the usability, but also avoids possible damage to the door assembly during use. At the same time, this design also enables the electrical appliance to better integrate into the home environment, improving the overall aesthetics of the home.

[0088] In an embodiment of another aspect of the present application, as Figures 1 to 6 shown, a refrigeration device is provided, including: a box body 4 and a door assembly as provided in any of the above embodiments. Wherein, the box body 4 forms a storage space, and the box door 2 is rotatably connected to the box body 4 and is adapted to open or close the storage space.

[0089] In this embodiment, the door body assembly includes: a cabinet door 2, a door panel 3, and a sliding door mechanism 1. The cabinet door 2 is rotatably connected to the cabinet body 4 and is adapted to open or close the storage space of the cabinet body 4; the door panel 3 is slidably disposed outside the cabinet door 2; the sliding door mechanism 1 is disposed on the cabinet door 2 and includes a base 13, a traction member 9, a first sliding member 11, a second sliding member 12, and a connecting member 15. A first groove 131 is formed on one side of the base 13, and a second groove 132 is formed on the other side; the first sliding member 11 is slidably disposed in the first groove 131; the second sliding member 12 is slidably disposed in the second groove 132 and is connected to the door panel 3; two ends of the connecting member 15 are respectively connected to the first sliding member 11 and the second sliding member 12; two ends of the traction member 9 are respectively rotatably connected to the cabinet body 4 and the first sliding member 11. During the opening or closing process of the cabinet door 2, the cabinet body 4 drives the first sliding member 11 to move in the first groove 131 through the traction member 9, and the first sliding member 11 drives the second sliding member 12 to move in the second groove 132 in the opposite direction through the connecting member 15, so as to drive the door panel 3 to move in the width direction of the cabinet door 2. The width direction of the cabinet door 2 is parallel to the plane where the cabinet door 2 is located and perpendicular to the rotating shaft of the cabinet door 2, so that the door panel 3 can move away from or close to the hinge 5 of the cabinet door 2.

[0090] By providing the door panel 3 on the cabinet door 2, when the refrigeration device is an inlaid type and is disposed in a groove-shaped space or between two cabinet bodies, the door panel 3 can be set flush with the side wall of the groove or the cabinet bodies on both sides, so as to reduce the gap between the refrigeration device and the adjacent wall or cabinet body, making it more beautiful.

[0091] Meanwhile, when the cabinet door 2 rotates, the sliding door mechanism 1 can drive the door panel 3 to move relative to the cabinet door 2 during the rotation process of the cabinet door 2 to move as far away as possible from obstacles such as the wall or cabinet body on the side door of the cabinet body 4, so as to prevent these obstacles from blocking the door panel 3 and affecting the rotation of the cabinet door 2, resulting in the cabinet door 2 being unable to be opened or closed normally. The combination of the sliding door mechanism 1, the cabinet door 2, and the door panel 3 enables the refrigeration device to avoid interference between the door panel 3 and surrounding objects during both opening and closing, greatly improving the convenience of use. Especially in a narrow kitchen environment, this design advantage is more obvious.

[0092] It can be understood that if the door body assembly has the beneficial effects of the above embodiment, the refrigeration device correspondingly has the beneficial effects of the above embodiment. The specific implementation manner can refer to the above embodiment, and details will not be repeated in this application.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention 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 invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered within the scope of the claims of the present invention.
