[0050] The following will describe the sliding door mechanism, door body assembly, and refrigeration device of the present application in conjunction with Figures 1 to 5 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 in 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 in the present application can also be applied as a freezer or any other suitable device.

[0051] In one embodiment of the present application, as Figures 3 to 5 shown, the sliding door mechanism 1 is used to be arranged on the cabinet door 2. The sliding door mechanism 1 includes a base 13, a first slider 11, a second slider 12, a first rotating member 14, a second rotating member 15, and a soft lock 16. 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 arranged on the first guide rail 131; the second slider 12 is slidably arranged on the second guide rail 132 and is used to be connected to the door panel 3; the first rotating member 14 is rotatably arranged on the first slider 11; the second rotating member 15 is used to be rotatably arranged on the cabinet body 4; the soft lock 16 bypasses both sides of the base 13, and both ends of the soft lock 16 are respectively connected to both ends of the second slider 12 and are in transmission connection with the first rotating member 14 and the second rotating member 15. The first slider 11 is hung on the soft lock 16 through the first rotating member 14; during the opening or closing process of the cabinet door 2, the soft lock 16 pulls the first slider 11 to move on the first guide rail 131 through the first rotating member 14, and the soft lock 16 drives the second slider 12 to move in the opposite direction on the second guide rail 132, so as to drive the door panel 3 to move relative to the width direction of the cabinet door 2 through the second slider 12.

[0052] Specifically, as Figure 3 and Figure 4As shown in the figure, the first guide rail 131 is located inside the base 13, providing a sliding track for the first slider 11. The second guide rail 132 is located outside 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 flexible lock 14 on the first slider 11 is in transmission connection with the flexible lock 16. The second slider 12 is slidably arranged on the second guide rail 132 and is used to connect with the door panel 3. Since the flexible lock 16 is in transmission connection with the second rotating member 15 on the box body 4, and at the same time the flexible lock 16 is in transmission connection with the first rotating member 14 on the first slider 11, and the flexible lock 16 is connected with the second slider 12.

[0053] When the box door 2 is opened or closed, the second rotating member 15 on the box body 4 drives the first rotating member 14 to rotate through the flexible lock 16. The first slider 11 moves in one direction along the first guide rail 131 through the first rotating member 14, and the flexible lock 16 drives the second slider 12 to move in the opposite direction along the second guide rail 132. Since the door panel 3 is connected with the second slider 12, and in combination with the characteristic that the first slider 11 and the second slider 12 move in opposite directions, the door panel 3 can slide relative to the width direction of the box body 4.

[0054] The sliding door mechanism 1 provided by the present utility model respectively arranges the first slider 11 and the second slider 12 on the first guide rail 131 and the second guide rail 132, sets the first rotating member 14 on the first slider 11, sets the second rotating member 15 on the box body 4, and is connected with the second slider 12 through the flexible lock 16 and is in transmission connection with the first rotating member 14 and the second rotating member 15. During the opening or closing process of the box door 2, the flexible lock 16 can drive the first slider 11 to move on the first guide rail 131 by cooperating with the first rotating member 14 and the second rotating member 15, and the second slider 12 can move in the opposite direction along the second guide rail 132 under the traction of the flexible lock 16, so that the door panel 3 moves relative to the width direction of the box door 2. Thereby, 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 use requirements of users in different scenarios.

[0055] 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.

[0056] From the perspective of materials, the first slider 11 and the second slider 12 can select 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 sliders, reduce wear and noise during the sliding process, and ensure the smoothness of sliding.

[0057] In a specific embodiment, as Figure 3 and Figure 4 shown, the first rotating member 14 includes a first rolling shaft 141, and the second rotating member 15 includes a second rolling shaft 151. The first rolling shaft 141 is rotatably arranged on the first slider 11, and the second rolling shaft 151 is used to be rotatably arranged on the box body 4; the flexible lock 16 includes a chain, the chain bypasses both sides of the base 13, and both ends are respectively connected to both ends of the second slider 12, and the chain is in transmission connection with the first rolling shaft 141 and the second rolling shaft 151. The first slider 11 is hung on the chain through the first rolling shaft 141.

[0058] Specifically, the first rolling shaft 141 is firmly installed on the first slider 11. Since the first slider 11 is hung on the chain, it can cooperate with the first slider 11 to smoothly roll on the first guide rail 131. Similarly, the second rolling shaft 151 is designed on the box body 4 to cooperate with the transmission path of the chain to realize the input and transmission of power. The chain, as the flexible lock 16, has both ends firmly connected to both ends of the second slider 12 respectively, forming a stable transmission link. When the chain bypasses both sides of the base 13, it is in transmission connection with the first rolling shaft 141 and the second rolling shaft 151 at the same time, and the chain is also connected to the second slider 12. This design ensures that power can be efficiently transmitted from the box body 4 to the door panel 3, driving the door panel to smoothly move in the width direction of the door 2.

[0059] During the opening or closing process of the door 2, the user operates the door 2 (such as pulling or pushing), so that the second rolling shaft 151 on the box body 4 starts to rotate. This rotation is quickly transmitted to the first rolling shaft 141 through the chain, and then drives the first slider 11 to move in a certain direction on the first guide rail 131. At the same time, the other end of the chain pulls the second slider 12 to move in the opposite direction on the second guide rail 132. Since the door panel 3 is tightly connected to the second slider 12, the door panel can smoothly slide along with the movement of the second slider, thus realizing the opening or closing action of the door panel. This transmission method combining the rolling shaft and the chain not only improves the operation efficiency and stability of the sliding door mechanism, but also makes the movement of the door panel 3 smoother and more accurate.

[0060] In some embodiments, as Figure 3 and Figure 4 shown, the first rotating member 14 further includes a first mounting plate 142, and the second rotating member 15 further includes a second mounting plate 152; the first mounting plate 142 is connected to the first slider 11, the first rolling shaft 141 is rotatably arranged on the first mounting plate 142, the second mounting plate 152 is used to be connected to the box body 4, and the second rolling shaft 151 is rotatably arranged on the second mounting plate 152.

[0061] Specifically, the first rotating member 14 not only includes the first rolling shaft 141, but also introduces the first mounting plate 142. The first mounting plate 142, as a stable support structure, is connected to the first slider 11, providing a stable and reliable mounting platform for the first rolling shaft 141. The first rolling shaft 141 is rotatably arranged on the first mounting plate 142 through appropriate bearings or bushings, ensuring its smoothness and stability during the transmission process.

[0062] Similarly, the second rotating member 15 has also been correspondingly improved. In addition to the second rolling shaft 151, a second mounting plate 152 is added. The second mounting plate 152 is designed to be connected to the box body 4 and fixed to the box body by bolts, welding or other reliable connection methods to provide stable support. The second rolling shaft 151 is also rotatably arranged on the second mounting plate 152 through bearings or bushings, ensuring its transmission connection with the chain and smooth rotation.

[0063] By adding the first mounting plate 142 and the second mounting plate 152, the first rotating member 14 and the second rotating member 15 not only have the rotating function, but also enhance the overall structural stability through the addition of the mounting plates. During the opening or closing process of the box door 2, even when facing a large external force, the first rolling shaft 141 and the second rolling shaft 151 can maintain a stable rotating state and are not prone to loosening or deviation. At the same time, the mounting plates can also disperse the stress and impact force generated during the transmission process, further extending the service life of the sliding door mechanism 1.

[0064] Optionally, the first mounting plate 142 and the first slider 11 are integrally formed, and / or the second mounting plate 152 and the box body 4 are integrally formed.

[0065] In the embodiment where the first mounting plate 142 and the first slider 11 are integrally formed, the first mounting plate 142 and the first slider 11 are combined into a single integral part during the manufacturing process through injection molding, die casting or other suitable processing means. This not only simplifies the assembly process, reduces the number of parts, but also enhances the connection strength between the two, avoiding loosening or separation problems caused by long-term use or external forces. At the same time, the integrally formed design also helps to improve the accuracy and stability of the entire sliding door mechanism, making the rotation of the first rolling shaft 141 smoother and more stable.

[0066] Similarly, in the embodiment where the second mounting plate 152 is integrally formed with the box body 4. The tight connection between the second mounting plate 152 and the box body 4 avoids the loosening problem caused by improper installation or long-term use. In addition, the integral forming also reduces the errors and uncertainties in the assembly process, improving the reliability and durability of the entire sliding door mechanism 1. During the manufacturing process of the box body 4, the second mounting plate 152 can be directly processed and formed as a part of the box body 4, thus simplifying the production process and reducing the manufacturing cost.

[0067] In summary, by selecting the design scheme of integrally forming the first mounting plate 142 with the first slider 11 and integrally forming the second mounting plate 152 with the box body 4, the integrity, structural strength and reliability of the sliding door mechanism 1 can be significantly improved.

[0068] In some embodiments, such as Figure 3 and Figure 4 As shown. In order to cooperate with the transmission and guidance of the flexible lock 16, a third rolling shaft 17 for tensioning the flexible lock 16 is provided on the first guide rail 131 and / or the second guide rail 132, and at least a part of the flexible lock 16 is pressed on the third rolling shaft 17.

[0069] Among them, the third rolling shaft 17 is installed at an appropriate position on the first guide rail 131 and / or the second guide rail 132. When the flexible lock 16 (such as a chain) moves on the guide rail, at least a part of it will be pressed on the third rolling shaft 17. In this way, the rotation of the third rolling shaft 17 can also provide a stable guiding effect for the flexible lock 16 and tension the flexible lock 16 to prevent it from shifting or shaking during the movement. This is crucial for ensuring the smoothness and accuracy of the door panel 3 during the opening or closing process of the box door 2.

[0070] It should be noted that the number and position of the third rolling shafts 17 can be adjusted according to specific design requirements. For example, the third rolling shafts 17 can be provided on both the first guide rail 131 and the second guide rail 132 to provide more comprehensive support and guidance. At the same time, the specific specifications and installation methods of the third rolling shafts 17 can also be determined according to factors such as the material, size and transmission method of the flexible lock 16.

[0071] In some embodiments, such as Figure 4As shown, the sliding door mechanism 1 further includes: a first fixed seat 18 and a second fixed seat 19. The first fixed seat 18 is connected to one end of the base 13 and is formed with a first limiting groove. The two ends of the first limiting groove are docked with one ends of the first guide rail 131 and the second guide rail 132, and a part of the flexible lock 16 is slidably disposed in the first limiting groove; the second fixed seat 19 is connected to the other end of the base 13 and is formed with a second limiting groove. The two ends of the second limiting groove are docked with the other ends of the first guide rail 131 and the second guide rail 132, and a part of the flexible lock 16 is slidably disposed in the second limiting groove.

[0072] In this embodiment, the first fixed seat 18 is connected to one end of the base 13, and the first limiting groove is docked with one ends of the first guide rail 131 and the second guide rail 132, forming a smooth transition area. The flexible lock 16 can slide freely 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 flexible lock 16 during movement but also improves the operating efficiency and stability of the entire sliding door mechanism 1. Similarly, the second fixed seat 19 is connected to the other end of the base 13 and forms a second limiting groove. The second limiting groove is docked with the other ends of the first guide rail 131 and the second guide rail 132. The flexible lock 16 is slidably disposed in the second limiting groove. The existence of the first limiting groove and the second limiting groove not only provides stable guidance for the flexible lock 16 but also limits the movement range of the flexible lock 16 through its structural characteristics.

[0073] Optionally, in order to facilitate the 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 18 and / or the second fixed seat 19. 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 fixed seat to firmly fix the sliding door mechanism to the external structure (the box door 2). 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 by tightening or riveting.

[0074] In some embodiments, as Figures 3 to 4 shown, rotatable support bearings can be provided in the first limiting groove and / or the second limiting groove as needed; a part of the flexible lock 16 is pressed on the support bearings in the first limiting groove; and / or, a part of the flexible lock 16 is pressed on the support bearings in the second limiting groove.

[0075] Specifically, when a support bearing is arranged in the first limit groove, a part of the flexible lock 16 is pressed on these support bearings. The rolling characteristics of the support bearings enable the first connecting piece to pass through the first limit groove more smoothly during the sliding process, reducing wear and noise caused by direct friction. Similarly, if a support bearing is also arranged in the second limit groove, the corresponding part on the flexible lock 16 is also pressed on these bearings to achieve a similar smooth sliding effect.

[0076] 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. In actual applications, they are reasonably arranged according to the specific design and usage requirements of the sliding door mechanism 1 to achieve the best sliding effect and support stability.

[0077] In an embodiment of the present application, as Figures 1 to 5 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 on the outer side of 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 first slider 11, a second slider 12, a first rotating member 14, a second rotating member 15, and a flexible lock 16. 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 arranged on the first guide rail 131; the second slider 12 is slidably arranged on the second guide rail 132 and is used to connect with the door panel 3; the first rotating member 14 is rotatably arranged on the first slider 11; the second rotating member 15 is rotatably arranged on the box body 4; the flexible lock 16 bypasses both sides of the base 13, and both ends of the flexible lock 16 are respectively connected to both ends of the second slider 12 and are in transmission connection with the first rotating member 14 and the second rotating member 15. The first slider 11 is hung on the flexible lock 16 through the first rotating member 14; during the opening or closing process of the box door 2, the flexible lock 16 pulls the first slider 11 to move on the first guide rail 131 through the first rotating member 14, and the flexible lock 16 drives the second slider 12 to move in the opposite direction on the second guide rail 132 to drive the door panel 3 to move relative to the width direction of 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 rotating shaft 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 Figure 1As shown by the middle arc arrow, 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 obstacles on the outside. During the process of the cabinet door 2 rotating and closing towards the cabinet body 4, the sliding door mechanism 1 drives the door panel 3 to slide towards the hinge 5, thereby preventing the door panel 3 from interfering with obstacles after closing.

[0079] For the door body assembly according to the embodiment of the present application, the cabinet door 2 is rotatably connected to the cabinet body 4, the door panel 3 is slidably arranged outside the cabinet door 2, and the sliding door mechanism 1 is arranged on the cabinet door 2. The sliding door mechanism 1 connects the cabinet door 2 and the door panel 3 to drive the door panel 3 to slide in the width direction of the cabinet door 2 during the process of the cabinet door 2 rotating and opening or closing relative to the cabinet body 4, so that the door panel 3 can avoid obstacles such as side walls and objects during the closing or opening of the cabinet door 2, preventing the door panel 3 from interfering with obstacles and affecting the rotation of the cabinet door 2, thereby meeting 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 cabinet 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 outside of the installation space 8. This design enables the door body assembly and the cabinet body 4 to be integrally embedded into the cabinet. During the process of the cabinet 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 away from or towards the hinge 5 on the cabinet door 2, 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 cabinet 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 away from or towards the hinge 5 on the cabinet door 2. 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.

[0082] For example, as Figure 1 and Figure 2 shown, during the opening process of the cabinet door 2, the sliding door mechanism 1 drives the door panel 3 to move a preset distance along the cabinet door 2 away from the hinge 5. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet body 7, enabling the cabinet door 2 to be fully opened, facilitating users to access items.

[0083] Similarly, during the closing process of the cabinet door 2, the sliding door mechanism 1 drives the door panel 3 to move a preset distance along the cabinet door 2 towards the hinge 5. In this way, the door panel 3 can smoothly avoid the side wall of the first cabinet body 6, enabling the cabinet door 2 to be fully closed, maintaining the overall aesthetics and sealing performance.

[0084] This design not only improves the usability but also avoids potential damage to the door body components during use. At the same time, this design also enables the appliance to better integrate into the home environment, enhancing the overall aesthetics of the home.

[0085] In one 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.

[0086] 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 component, etc.) adapted to the slot is provided on the door panel 3, so as to mount 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 usage requirements in different scenarios.

[0087] Generally, for simplicity of installation, the sliding door mechanism 1 is connected to the top of the cabinet door 2. Mounting the sliding door mechanism 1 on the top of the cabinet door 2 can significantly reduce the steps and complexity required during installation. Top mounting usually only requires reserving appropriate positions at the top of the cabinet door and then fixing the sliding door mechanism 1 at these positions. In contrast, if the sliding door mechanism 1 is selected to be installed on the side of the cabinet door 2 or in the cabinet door 2, more fixing points and support structures may be required, thus increasing the difficulty and cost of installation.

[0088] In another embodiment of the present application, as Figures 1 to 5 shown, a refrigeration device is provided, including: a cabinet 4 and a door body component as provided in any of the above embodiments. Among them, the cabinet 4 forms a storage space, and the cabinet door 2 is rotatably connected to the cabinet 4 and is adapted to open or close the storage space. In this embodiment, the structure of the door body component can refer to the above embodiments and will not be elaborated here.

[0089] In this embodiment, 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 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.

[0090] At the same time, 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 of the cabinet door 2 to move as far as possible away from obstacles such as the wall or cabinet on the side of the cabinet body 4 of the door panel 3, 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 normally opened or closed. 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 when opening and closing, greatly improving the usability. Especially in a narrow kitchen environment, this design advantage is more obvious.

[0091] It can be understood that since the door body assembly has the beneficial effects of the above embodiments, the refrigeration device correspondingly has the beneficial effects of the above embodiments. For the specific implementation manners, reference may be made to the above embodiments, and details thereof will not be elaborated in this application.

[0092] 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.
