[0055] The following will describe the sliding door mechanism, door body assembly, and refrigeration equipment of the present application in conjunction with Figures 1 to 7 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 sliding door mechanism and door body assembly in the present application can also be applied to dishwashers, washing machines, or any other suitable equipment. The refrigeration equipment in the present application is, for example, applied as a refrigerator. However, it should be understood that the refrigeration equipment in the present application can also be applied as a freezer or any other suitable equipment.

[0056] In one embodiment of the present application, as Figures 1 to 6 shown, the sliding door mechanism 1 is applied to a refrigeration equipment, and the refrigeration equipment 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 outside the door 2; the sliding door mechanism 1 includes a base 13, a first slider 11, a second slider 12, a traction member 14, and a connecting member. One side of the base 13 is formed with a first guide rail 131, and the other side is formed with a second guide rail 132; the first slider 11 is slidably disposed on the first guide rail 131, and a first rack 111 is constructed on the first slider 11; the second slider 12 is slidably disposed on the second guide rail 132 and is connected to the door panel 3; both ends of the connecting member are respectively connected to the first slider 11 and the second slider 12; both ends of the traction member 14 are in transmission connection with the first rack 111 and the box body 4; in the case where the box body 4 drives the traction member 14 to rotate, the traction member 14 drives the first slider 11 to move on the first guide rail 131, and the first slider 11 drives the second slider 12 to move in the opposite direction on the second guide rail 132 through the connecting member, so as to drive the door panel 3 to move relative to the width direction of the door 2.

[0057] Specifically, as Figure 3As shown, the first guide rail 131 is located at the top of the base 13, providing a sliding track for the first slider 11. The second guide rail 132 is located at the bottom of the base 13, parallel to or at a certain angle with the first guide rail 131 (manufacturing and installation errors should be considered, about plus or minus 10°), providing a sliding track for the second slider 12. The first slider 11 is slidably arranged on the first guide rail 131, and the first slider 11 is used for driving connection with the box body 4 through the traction member 14. The second slider 12 is slidably arranged on the second guide rail 132 and is used for connection with the door panel 3. The connecting member can be a connecting component such as a traction rope or a transmission belt, and both ends of the connecting member are respectively connected with the first slider 11 and the second slider 12. The traction member 14 meshes with the first rack 111 on the first slider 11.

[0058] When the traction member 14 drives the first slider 11 to move on the first guide rail 131 under the driving force through the first rack 111, since both ends of the connecting member are respectively fixed to the first slider 11 and the second slider 12, by reasonably setting the extending direction of the connecting member, the connecting member will drive the second slider 12 to move in the opposite direction on the second guide rail 132. This characteristic of synchronous reverse movement enables the first slider 11 to be drivingly connected with the box body 4 through the traction member 14 and the second slider 12 to be connected with the door panel 3. When the box door 2 is opened or closed, through the meshing of the traction member 14 and the first rack 111, the first slider 11 moves, and the first slider 11 drives the second slider 12 to move in the opposite direction on the second guide rail 132 through the connecting member, so that the second slider 12 drives the door panel 3 to be able to slide relative to the width direction of the box body 4.

[0059] The sliding door mechanism 1 provided by the present utility model, by respectively arranging the first slider 11 and the second slider 12 on the first guide rail 131 and the second guide rail 132, connecting the first slider 11 and the second slider 12 with the connecting member, and meshing the traction member 14 with the first rack 111 on the first slider 11, enables the second slider 12 to move in the opposite direction when the traction member 14 drives the first slider 11 to move. Thus, when the first slider 11 is drivingly connected with the box body 4 through the traction member 14 and the second slider 12 is connected with the door panel 3, the sliding door mechanism 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 to meet the usage requirements of users in different scenarios.

[0060] It should be noted that in practical applications, the designs of the first slider 11 and the second slider 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.

[0061] From the material point of view, the first slider 11 and the second slider 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 is intended to improve the durability of the sliders, reduce wear and noise during sliding, and ensure smooth sliding.

[0062] In some embodiments, Figures 3 to 7 As shown, the traction member 14 includes: a connecting piece 143, a first connecting rod 141 and a second connecting rod 142. The connecting piece 143 is used to be connected to the box body 4; the first connecting rod 141 is rotatably connected to the second connecting rod 142, and one end of the first connecting rod 141 away from the second connecting rod 142 is rotatably connected to the connecting piece 143, and one end of the second connecting rod 142 away from the first connecting rod 141 is configured with a second rack 1421 meshing with the first rack 111.

[0063] In this embodiment, the connecting piece 143 is used as the fixed end of the traction member 14. Its structural design takes into account stability and easy installation, and is made of high-strength alloy material. A plurality of mounting holes can be set on the connecting piece 143 as needed to meet the installation requirements of different boxes 4. At the same time, it is equipped with locking screws or quick release devices to facilitate users to quickly install or disassemble as needed. The rotation connection between the first connecting rod 141 and the second connecting rod 142 adopts a bearing to ensure the smoothness and low noise of the two during the rotation process. This design not only improves the transmission efficiency, but also extends the service life of the traction member 14. At the same time, the end of the second connecting rod 142 away from the first connecting rod 141 is constructed with a precision-machined second rack 1421, and the second rack 1421 is arranged on the second connecting rod 142 in an arc shape. The second rack 1421 is precisely meshed with the first rack 111 on the first slider 11 to cooperate with the rotation of the box door 2.

[0064] When the first slider 11 is connected to the box body 4 through the traction member 14 and the second slider 12 is connected to the door panel 3, if the user pushes the box door 2 to rotate relative to the box body 4, the connecting piece 143, the first connecting rod 141 and the second connecting rod 142 in the traction member 14 rotate with each other, and the second rack 1421 rotates to drive the first rack 111 to move, so that the first slider 11 is driven to move on the first guide rail 131, and the connecting member drives the second slider 12 to move in the opposite direction on the second guide rail 132, thereby driving the door panel 3 to slide relative to the width direction of the box door 2.

[0065] To further improve the intelligence level of the sliding door mechanism 1, sensors can also be provided in the traction member 14. For example, a position sensor can be installed on the connecting piece 143 or the first connecting rod 141 to monitor the working state and position information of the sliding door mechanism 1 in real time, and transmit the data to the outside through a wireless communication module. Precise control and adjustment of the sliding door mechanism 1 can be carried out according to the received data to achieve functions such as automatic opening and closing, anti-pinch protection, etc.

[0066] In some embodiments, as Figures 3 to 7 shown, the connecting member is a rope, and the connecting member includes a first connecting member and a second connecting member. The first connecting member bypasses one end of the base 13, and its two ends are respectively connected to one end of the first slider 11 and the second slider 12; the second connecting member bypasses the other end of the base 13, and its two ends are respectively connected to the other ends of the first slider 11 and the second slider 12.

[0067] Specifically, one end of the first connecting member is fixed at a predetermined position of the first slider 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 slider 12. In this way, when the first slider 11 moves on the first guide rail 131, the first connecting member can smoothly transmit this movement and drive the second slider 12 to move in the opposite direction on the second guide rail 132.

[0068] 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 sliders. One end of the second connecting member is fixed at another predetermined position of the first slider 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 slider 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.

[0069] 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 two sliders during movement.

[0070] In some embodiments, as Figures 3 to 7 shown, the sliding door mechanism 1 further includes: a first fixed seat 15 and a second fixed seat 16. The first fixed seat 15 is connected to one end of the base 13, and a first limiting groove is formed. The two ends of the first limiting groove are docked with one end of the first guide rail 131 and the second guide rail 132, and a part of the first connecting member is slidably disposed in the first limiting groove; the second fixed seat 16 is connected to the other end of the base 13, and a second limiting groove is formed. The two ends of the second limiting groove are docked with the other end of the first guide rail 131 and the second guide rail 132, and a part of the second connecting member is slidably disposed in the second limiting groove.

[0071] In this embodiment, the first fixing seat 15 is connected to one end of the base 13. The first limiting groove is butted with one ends of the first guide rail 131 and the second guide rail 132 to form a smooth transition area. The first connecting member (i.e., a part of the rope) can freely slide in this limiting groove and is simultaneously subject to certain constraints to ensure that it moves 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 fixing seat 16 is connected to the other end of the base 13 and forms a second limiting groove. The second limiting groove is butted with the other ends of the first guide rail 131 and the second guide rail 132. The second connecting member (also a part of the rope) is slidably disposed in the second limiting groove and cooperates with the first connecting member to jointly drive the synchronous reverse movement of the first slider 11 and the second slider 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.

[0072] 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 fixing seat 15 and / or the second fixing seat 16. The positions and numbers of these fixing holes are determined according to the connection method and requirements of the external structure. The sliding door mechanism 1 further includes fasteners, which are used to pass through the fixing holes on the fixing seat to firmly fix the sliding door mechanism to the external structure. The fasteners can be fasteners in the form of bolts, screws, rivets, etc., and the specific selection depends on the actual application scenario 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 structure to achieve a firm connection through tightening or riveting, etc.

[0073] In some embodiments, as Figures 3 to 7 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.

[0074] Specifically, when support bearings are provided 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 sliding, reducing the wear and noise generated by direct friction. Similarly, if support bearings are also provided in the second limiting groove, the corresponding part of the second connecting member is pressed on these bearings to achieve a similar smooth sliding effect.

[0075] 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 number of bearings are also adjusted as needed. Generally, at least two bearings are required to support the first connecting member and the second connecting member respectively. In practical 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.

[0076] In summary, by providing 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.

[0077] In one embodiment of the present application, as Figures 1 to 7 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 disposed outside the box door 2; the sliding door mechanism 1 is disposed on the box door 2, and the sliding door mechanism 1 includes a base 13, a first slider 11, a second slider 12, a traction member 14, and a connecting member. A first guide rail 131 is formed on one side of the base 13, and a second guide rail 132 is formed on the other side; the first slider 11 is slidably disposed on the first guide rail 131, and a first rack 111 is formed on the first slider 11; the second slider 12 is slidably disposed on the second guide rail 132 and is connected to the door panel 3; both ends of the connecting member are respectively connected to the first slider 11 and the second slider 12; both ends of the traction member 14 are in transmission connection with the first rack 111 and the box body 4; in the case where the box body 4 drives the traction member 14 to rotate, the traction member 14 drives the first slider 11 to move on the first guide rail 131, and the first slider 11 drives the second slider 12 to move in the opposite direction on the second guide rail 132 through the connecting member, so as to drive the door panel 3 to move in the width direction of the box door 2 relative to the box door 2. The width direction of the box door 2 is parallel to the plane where the box door 2 is located and perpendicular to the rotation axis of the box door 2, so that the door panel 3 can move away from or close to the hinge 5 of the box door 2.

[0078] Specifically, during the process of the box door 2 rotating outward to open 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, thereby preventing the door panel 3 from interfering with external obstacles. During the process of the box door 2 rotating toward the box body 4 to close, the sliding door mechanism 1 drives the door panel 3 to slide toward the hinge 5, thereby preventing the door panel 3 from interfering with obstacles after closing.

[0079] 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 on the outer side of the box door 2, and a 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 that during the process of the box door 2 rotating relative to the box body 4 to open or close, the door panel 3 is driven to slide in the width direction of the box door 2, so that the door panel 3 can avoid obstacles such as side walls and objects on the side during the closing or opening process of the box door 2, and prevent the door panel 3 from interfering with the obstacles and affecting the rotation of the box door 2, so as to meet the usage requirements of users in different scenarios.

[0080] In some embodiments, as Figure 1 and Figure 2 shown, the door body assembly and the box body 4 are used to be arranged in the installation space 8 formed between the first cabinet body 6 and the second cabinet body 7. There is an opening on the outer side of the installation space 8. This design enables the door body assembly and the box body 4 to be integrally embedded into the cabinet body. During the process of the box door 2 passing 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.

[0081] During the process of the box door 2 passing 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 prevent the door panel 3 from interfering with 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.

[0082] For example, as Figure 1 and Figure 2 shown, during the opening process of 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 access items.

[0083] Similarly, during the closing process of 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.

[0084] This design not only improves the usage convenience, but also avoids possible damage to the door body assembly during use. At the same time, this design also enables the electrical appliance to better integrate into the home environment and improves the overall aesthetics of the home.

[0085] To prevent the first rack 111 from disengaging from the second rack 1421 during rotation, the sliding door mechanism 1 further includes: a fixing member 17. One end of the fixing member 17 is rotatably connected to the traction member 14, and the other end of the fixing member 17 is rotatably connected to the cabinet door 2.

[0086] In this embodiment, the traction member 14 rotates freely under the connection of the fixing member 17 while maintaining its overall stability. During the operation of the sliding door mechanism 1, due to the rotation of the traction member 14 and the movement of the first slider 11 on the first guide rail 131, certain vibrations or offsets may occur. Without the support and stabilizing effect of the fixing member 17, the first rack 111 and the second rack 1421 may disengage from meshing due to vibrations or offsets, resulting in the abnormal operation of the sliding door mechanism. The presence of the fixing member 17 effectively limits the offset range of the traction member 14 through the rotational connections at both ends and ensures the stable meshing between the first rack 111 and the second rack 1421. Even when vibrations or external impacts are encountered during the operation of the sliding door mechanism, the fixing member 17 can provide sufficient support and stability to prevent the disengagement between the first rack 111 and the second rack 1421.

[0087] In an embodiment of the present application, as Figure 3 shown, a connecting block is provided on the second slider 12, and a slot for hanging the door panel 3 is formed on the connecting block.

[0088] In this embodiment, by providing a connecting block on the second slider 12 and a slot on the connecting block, correspondingly, a connecting component (such as a hook, a plug-in member, etc.) adapted to the slot is provided on the door panel 3 to install the door panel 3 on the connecting block, enabling the door panel 3 to slide with the second slider 12. At the same time, it also facilitates the user to remove the door panel 3 from the second slider 12 when needed, meeting the user's different usage requirements in different scenarios.

[0089] In some embodiments, as Figure 4 shown, a hook 31 is provided on the door panel 3, and the door panel 3 is hung on the connecting block through the hook 31.

[0090] Among them, the hook 31 is used as the connection method between the door panel 3 and the connecting block. The hook 31 is usually designed to have sufficient strength and toughness to ensure that it can bear the weight of the door panel 3 and various forces and vibrations that may occur during use. At the same time, the shape and size of the hook 31 also need to match the slot on the connecting block to ensure that the door panel 3 can be firmly hung on the connecting block without shaking or falling off. One or more hooks 31 can be provided as needed to increase the connection effect and connection positions between the door panel 3 and the second slider 12 to adapt to different usage scenarios and requirements.

[0091] In an embodiment of another aspect of the present application, as Figures 1 to 7As shown in the figure, a refrigeration device is provided, including: a box body 4 and a door assembly provided in any of the above embodiments. Among them, 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.

[0092] In this embodiment, the door 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 disposed outside the box door 2; the sliding door mechanism 1 is disposed on the box door 2, and the sliding door mechanism 1 includes a base 13, a first slider 11, a second slider 12, a traction member 14, and a connecting member. One side of the base 13 forms a first guide rail 131, and the other side forms a second guide rail 132; the first slider 11 is slidably disposed on the first guide rail 131, and a first rack 111 is constructed on the first slider 11; the second slider 12 is slidably disposed on the second guide rail 132 and is connected to the door panel 3; both ends of the connecting member are respectively connected to the first slider 11 and the second slider 12; both ends of the traction member 14 are in transmission connection with the first rack 111 and the box body 4; in the case where the box body 4 drives the traction member 14 to rotate, the traction member 14 drives the first slider 11 to move on the first guide rail 131, and the first slider 11 drives the second slider 12 to move in the opposite direction on the second guide rail 132 through the connecting member, so as to drive the door panel 3 to move relative to the width direction of the box door 2.

[0093] By providing the door panel 3 on the box door 2, when the refrigeration device is an embedded type and is disposed in a groove-shaped space, or is disposed between two cabinets, the door panel 3 can be set flush with the side wall of the groove or the cabinets on both sides, so as to reduce the gap between the refrigeration device and the adjacent wall or cabinet, making it more beautiful.

[0094] At the same time, when the box door 2 rotates, the sliding door mechanism 1 can drive the door panel 3 to move relative to the box door 2 during the rotation of the box door 2 to move as far away as possible from obstacles such as the wall or cabinet on the side of the side door of the box body 4, so as to prevent these obstacles from blocking the door panel 3 and affecting the rotation of the box door 2, resulting in the box door 2 being unable to be opened or closed normally. The combination of the sliding door mechanism 1, the box door 2, and the door panel 3 enables the refrigeration device to avoid interference between the door panel 3 and surrounding objects during opening and closing, improving the convenience of use. Especially in a narrow kitchen environment, this design advantage is more obvious.

[0095] It can be understood that if the door assembly has the beneficial effects of the above embodiments, the refrigeration device correspondingly has the beneficial effects of the above embodiments, and its specific implementation manners can refer to the above embodiments, and will not be elaborated in this application.
