[0070] The following will be combined with Figures 1 to 9 Describe the sliding door device, door body assembly and refrigeration equipment of the present application. The sliding door device and door body assembly in the present application can be applied to the cabinet door 2 or the cabinet door of household appliances, such as the cabinet door 2 of a refrigerator. However, it should be understood that the door body assembly of the present application can also be applied to any other suitable equipment. The refrigeration equipment in the present application is, for example, applied to a refrigerator. However, it should be understood that the refrigeration equipment of the present application can also be applied to a freezer or any other suitable equipment.

[0071] In an embodiment of the present application, as Figures 1 to 3 shown, the sliding door device is applied to a refrigeration equipment, the refrigeration equipment includes a box body 4, a box door 2 and a door panel 3. The box door 2 is rotatably connected to the box body 4. The box door 2 is adapted to open or close the storage space of the box body 4. The door panel 3 is slidably arranged on the outside of the box door 2.

[0072] In this embodiment, the sliding door device includes: a traction member 17, a main sliding door member 1, and a first driven sliding door member 9. The main sliding door member 1 is disposed on the cabinet door 2, and the main sliding door member 1 is drivingly connected to the cabinet body 4 through the traction member 17; the first driven sliding door member 9 is disposed on the cabinet door 2, the first driven sliding door member 9 is drivingly connected to the main sliding door member 1, and the first driven sliding door member 9 is connected to the door panel 3; during the opening or closing process of the cabinet door 2, the cabinet body 4 drives the main sliding door member 1 through the traction member 17, and the main sliding door member 1 drives the first driven sliding door member 9 to drive the door panel 3 to move relative to the width direction of the cabinet door 2 through the first driven sliding door member 9.

[0073] In this embodiment, the cabinet body 4 is the main part of the refrigeration device. A storage space is provided inside the cabinet body 4 for storing food or other items that need to be refrigerated or frozen. The cabinet door 2 is mounted on the cabinet body 4 through a certain rotational connection method (such as a hinge 5) and can rotate around one or more pivot points to open and close the storage space. The door panel 3 is an additional, slidable member disposed on the outer side of the cabinet door 2.

[0074] In this embodiment, the traction member 17 (such as a chain, a belt, or a steel wire rope) connects the cabinet body 4 and the main sliding door member 1. When the cabinet door 2 is opened or closed, power is transmitted to the main sliding door member 1 through the movement of the traction member 17. The main sliding door member 1 does not directly bear the weight of the door panel 3, but rather serves as the key to transmit power, converting the power from the traction member 17 into driving force for the first driven sliding door member 9. The first driven sliding door member 9 closely cooperates with the main sliding door member 1, directly connecting and driving the door panel 3 to move. Since the first driven sliding door member 9 bears the entire weight of the door panel 3, the design of the first driven sliding door member 9 needs to take into account both strength and flexibility to ensure the smooth sliding of the door panel 3.

[0075] During the opening or closing process of the cabinet door 2, the cabinet body 4 drives the main sliding door member 1 through the traction member 17. The main sliding door member 1 drives the first driven sliding door member 9 to drive the door panel 3 to move relative to the width direction of the cabinet door 2, thereby avoiding interference between the door panel 3 and external obstacles. During this process, the main sliding door member 1 that directly bears the driving force does not bear the weight of the door panel 3, while the first driven sliding door member 9 connected to the door panel 3 bears the entire weight of the door panel 3, so that during the opening or closing process of the cabinet door 2, it is possible to avoid the main sliding door member 1 from being subjected to external forces in other directions and reduce the problem of shaking when the door panel 3 moves relative to the cabinet door 2.

[0076] According to the sliding door device of the embodiment, by arranging the sliding door device including the traction component 17, the active sliding door component 1, and the first driven sliding door component 9 on the box door 2, the active sliding door component 1 is drivingly connected to the box body 4 through the traction component 17, and the first driven sliding door component 9 is drivingly connected to the active sliding door component 1, so that the box body 4 drives the active sliding door component 1 through the traction component 17, the active sliding door component 1 drives the first driven sliding door component 9, and the first driven sliding door component 9 drives the door panel 3 to move in the width direction of the box door 2 to avoid obstacles on both sides, thus solving the interference problem during the door opening process. At the same time, the active sliding door component 1 that directly bears the driving force of the sliding door device does not bear the weight of the door panel 3, while the first driven sliding door component 9 connected to the door panel 3 bears the weight of the entire door panel 3, so that during the opening or closing process of the box door 2, it is possible to avoid the active sliding door component 1 from bearing external forces in other directions and reduce the problem of the door panel 3 shaking when moving relative to the box door 2.

[0077] In some embodiments, as Figure 4 shown, the active sliding door component 1 includes: a first base 13, a first slider 11, a second slider 12, and a flexible cable 14. A first guide rail 131 is formed on one side of the first 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 and is connected to the box body 4 through the traction component 17; the second slider 12 is slidably arranged on the second guide rail 132 and is drivingly connected to the first driven sliding door component 9; both ends of the flexible cable 14 are respectively connected to the first slider 11 and the second slider 12. In the case where the box body 4 drives the first slider 11 to move on the first guide rail 131 through the traction component 17, the first slider 11 drives the second slider 12 to move in the opposite direction on the second guide rail 132 through the flexible cable 14.

[0078] In this embodiment, the first base 13 is fixed on the door 2, and a first guide rail 131 and a second guide rail 132 are respectively formed on its inner side and outer side. The first guide rail 131 and the second guide rail 132 respectively provide tracks for the sliding of the first slider 11 and the second slider 12. The first slider 11 is slidably sleeved on the first guide rail 131, connected to the box body 4 through a traction member 17, and driven by the box body 4 to move on the first guide rail 131. The second slider 12 is also slidably sleeved on the second guide rail 132, but is connected to the first driven sliding door member 9 for driving the first driven sliding door member 9. The flexible cable 14 can be a connecting member such as a traction rope or a transmission belt. The two ends of the flexible cable 14 are respectively connected to the first slider 11 and the second slider 12, so that the first slider 11 can drive the second slider 12 to move synchronously and move in opposite directions. This design ensures that during the process of the door panel 3 sliding along the width direction of the box body 4, only the driving force of the traction member 17 is borne by the first slider 11 and the second slider 12, and the weight of the door panel 3 in the vertical direction does not need to be borne. Only the first driven sliding door member 9 bears the weight of the entire door panel 3, reducing the problem of shaking when the door panel 3 moves relative to the door 2.

[0079] During the process of the door 2 rotating and opening towards the outside of the box body 4, the box body 4 drives the first slider 11 to slide towards the direction close to the hinge 5 through the traction member 17. At the same time, the first slider 11 drives the second slider 12 to slide in the opposite direction through the flexible cable 14, and the second slider 12 is used to drive the first driven sliding door member 9, and the first driven sliding door member 9 drives the door panel 3 to move, thereby avoiding interference between the door panel 3 and the outside obstacles. During the process of the door 2 rotating and closing towards one side of the box body 4, the box body 4 drives the first slider 11 to slide away from the hinge 5 through the traction member 17. At the same time, the first slider 11 drives the second slider 12 to slide in the opposite direction through the flexible cable 14, and the second slider 12 is used to drive the first driven sliding door member 9, and the first driven sliding door member 9 drives the door panel 3 to move, avoiding interference between the door panel 3 and the obstacles after closing.

[0080] In some embodiments, as Figure 4 shown, the flexible cable 14 includes: a first flexible cable and a second flexible cable. The first flexible cable bypasses one end of the first base 13, and the two ends are respectively connected to one end of the first slider 11 and the second slider 12. The second flexible cable bypasses the other end of the first base 13, and the two ends are respectively connected to the other end of the first slider 11 and the second slider 12.

[0081] In this embodiment, by passing the first flexible cable around one end of the first base 13 and connecting it to the first slider 11 and the second slider 12 respectively, when the first slider 11 slides away from this end of the first base 13 under the drive of the box body 4, the first slider 11 drives the second slider 12 to slide towards this end of the first base 13 through the first flexible cable; at the same time, by passing the second flexible cable around the other end of the first base 13 and connecting it to the first slider 11 and the second slider 12 respectively, when the first slider 11 slides away from the other end of the first base 13 under the drive of the box door 2, the first slider 11 drives the second slider 12 to slide towards the other end of the first base 13 through the second flexible cable, so that when the first slider 11 slides towards both ends of the first base 13 respectively, it can drive the second slider 12 to slide in the opposite direction to the first slider 11, and further cooperate with the first driven sliding door component 9 to enable the door panel 3 to slide relative to the box door 2 when the box door 2 is opened and closed, so as to avoid interference with obstacles and affect the opening and closing of the box door 2.

[0082] In some embodiments, as Figure 4 shown, the active sliding door component 1 further includes a first fixing seat 15 and a second fixing seat 16. The first fixing seat 15 is connected to one end of the first base 13 and is formed with a first limiting groove. The two ends of the first limiting groove are butted against one end of the first guide rail 131 and the second guide rail 132, and a part of the first flexible cable is slidably arranged in the first limiting groove; the second fixing seat 16 is connected to the other end of the first base 13 and is formed with a second limiting groove. The two ends of the second limiting groove are butted against the other end of the first guide rail 131 and the second guide rail 132, and a part of the second flexible cable is slidably arranged in the second limiting groove.

[0083] Specifically, the first fixing seat 15 is connected to one end of the first base 13, serving as an extension and support for the first guide rail 131 and the second guide rail 132 at this end. A first limiting groove is formed on the first fixing seat 15. The first limiting groove not only provides an additional sliding track for the first flexible cable but also ensures the stability and accuracy of the first flexible cable during the sliding process. Both ends of the first limiting groove are docked with one end of the first guide rail 131 and the second guide rail 132. The existence of the first limiting groove restricts the offset and sway of the first flexible cable during the sliding process, improving the operation precision and reliability of the entire active sliding door component 1. The second fixing seat 16 corresponds to the first fixing seat 15. The second fixing seat 16 is connected to the other end of the first base 13, providing support and extension for the first guide rail 131 and the second guide rail 132 at this end. A second limiting groove is formed on the second fixing seat 16, and its design is similar to that of the first limiting groove but is located at the other end of the active sliding door component 1. Both ends of the second limiting groove are docked with the other end of the first guide rail 131 and the second guide rail 132, providing guidance and limitation for the sliding of the second flexible cable. Similar to the first limiting groove, the second limiting groove also plays a role in restricting the offset and sway of the flexible cable 14.

[0084] In order to achieve the installation of the active slider mechanism, in some embodiments, such as Figure 4 shown, fixing holes are provided on the first fixing seat 15 and / or the second fixing seat 16. The active sliding door component 1 further includes fixing members. The fixing members pass through the fixing holes to be connected to the box door 2, so that the entire active sliding door component 1 can be fixed on the box door 2.

[0085] In this embodiment, by fixing the first fixing seat 15 and / or the second fixing seat 16 connected to the first base 13 on the box door 2 through the fixing members, it can be ensured that the mechanism will not loosen or shift due to external forces or vibrations during operation. The design of the fixing holes and the fixing members makes the installation process simple and fast. The operator only needs to align the fixing members with the fixing holes and tighten them to complete the connection between the active sliding door component 1 and the box door 2. When it is necessary to repair or replace the active sliding door component 1, the active sliding door component 1 can be removed from the box door 2 by simply removing the fixing members without complicated disassembly work. This greatly improves the maintainability and flexibility of the equipment.

[0086] During specific implementation, appropriate fixing members can be selected according to the structure and material of the box door 2, such as screws, bolts, rivets, etc. At the same time, it is also necessary to ensure that the position and size of the fixing holes match the fixing members to ensure the firmness and stability of the connection.

[0087] In some embodiments, such as Figure 4 、 Figure 5 and Figure 6As shown, the first driven sliding door component 9 has a C-shaped drawer track structure, including: a second base 91 and a third slider 92. The inner side of the second base 91 is connected to the second slider 12 through a fixing plate 95, the outer side is connected to the door panel 3, and a third guide rail 911 is formed inside the second base 91; the third slider 92 is slidably arranged in the third guide rail 911, and the third slider 92 is connected to the box door 2. When the second slider 12 moves on the second guide rail 132, the second slider 12 drives the second base 91 to move relative to the third slider 92 through the third guide rail 911.

[0088] In this embodiment, the inner side of the second base 91 is connected to the second slider 12, and the second base 91 moves as the second slider 12 moves on the second guide rail 132. At the same time, its outer side is directly connected to the door panel 3. In this way, when the second base 91 moves, it can drive the door panel 3 to move together. The inside of the second base 91 is designed with a third guide rail 911 for accommodating and guiding the sliding of the third slider 92. The third slider 92 not only interacts with the third guide rail 911 to achieve the sliding function, but it is also connected to the box door 2 (or possibly a part of the box door). This means that when the third slider 92 moves in the third guide rail 911, through the relative movement between the second base 91 and the third slider 92, the door panel 3 and the box door 2 move relative to each other.

[0089] When the second slider 12 moves along the second guide rail 132, since the inner side of the second base 91 is connected to the second slider 12, the second base 91 will also move accordingly. During this process, since the third slider 92 is fixed to the box door 2 and is slidably arranged in the third guide rail 911 of the second base 91, when the second base 91 moves, it will drive the door panel 3 to move correspondingly through the relative movement between the third guide rail 911 and the third slider 92.

[0090] In some embodiments, as Figures 4 to 6 shown, the first driven sliding door component 9 further includes: a first ball support. The first ball support 93 is slidably internally connected to the third guide rail 911, and the third slider 92 is slidably internally connected to the first ball support 93. When the second slider 12 moves on the second guide rail 132, it drives the second base 91 to move through a connecting member (such as a rod, a chain, etc.) or by direct action. As the second base 91 moves, the third slider 92 moves relative to it. At this time, with the assistance of the first ball support 93, the third slider 92 slides in the third guide rail 911 with low friction and high efficiency. Due to the presence of the first ball support 93, the sliding process of the third slider 92 becomes smoother and more reliable, thus ensuring the stable operation of the entire first driven sliding door component 9.

[0091] Specifically, the first ball support member 93 includes: a support frame and balls (not shown). The support frame is disposed between the third guide rail 911 and the third slider 92, and a limiting notch is formed on the support frame; the balls are rollably disposed in the limiting notch, one side of the balls abuts against the third guide rail 911, and the other side of the balls passes through the limiting notch and abuts against the third slider 92.

[0092] In this embodiment, the support frame is disposed between the third guide rail 911 and the third slider 92. It is used to ensure that the balls can roll in the correct position, thereby supporting the sliding of the third slider 92. A limiting notch is designed on the support frame to accommodate the balls and limit their rolling range. The limiting notch ensures that the balls do not break away from the support frame during the rolling process, and at the same time provides a certain rolling space for the balls. The balls are rollably disposed in the limiting notch, one side of them abuts against the third guide rail 911, and the other side passes through the limiting notch and abuts against the third slider 92. This design enables the third slider 92 to slide not by directly contacting and generating sliding friction with the third guide rail 911, but by the rolling of the balls. This method greatly reduces the frictional resistance during the sliding process and improves the sliding efficiency. Since the rolling of the balls is of low friction, it can significantly reduce the wear between the third slider 92 and the third guide rail 911. This helps to extend the service life of these two components and reduce the maintenance cost.

[0093] When the third slider 92 needs to slide along the third guide rail 911, the second base 91 is acted upon by an external driving force (such as the driving force from the second slider 12). During this process, the second base 91 will push the balls to roll in the limiting notch of the support frame. One side of the balls remains in contact with and rolls along the third guide rail 911, while the other side remains in contact with and rolls along the third slider 92. In this way, the first ball support member 93 provides stable and efficient support for the sliding of the third slider 92.

[0094] In summary, the first ball support member 93 in this embodiment realizes the effective support and assistance for the sliding of the third slider 92 in the third guide rail 911 through the combined design of the support frame and the balls, effectively improving the sliding efficiency.

[0095] In addition, as Figure 5 and Figure 6As shown, a limiting member 912 is provided on the third guide rail 911, and the limiting member 912 is located on both sides of the third slider 92; when the third slider 92 moves within the third guide rail 911, the movement range of the third slider 92 is restricted by the contact between the limiting member 912 and the third slider 92. The limiting member 912 should be precisely installed at the appropriate position on the third guide rail 911 to ensure that they can effectively limit the movement range of the third slider 92. Generally, the position of the limiting member 912 is determined according to the movement requirements of the door panel 3 and the cabinet door 2. The shape and size of the limiting member 912 should be determined according to the contour and movement of the third slider 92 to withstand the impact force generated during contact with the third slider 92 and maintain a stable limiting effect.

[0096] During operation, when the third slider 92 moves within the third guide rail 911, the second base 91 will slide under the action of an external driving force (such as the driving force from the second slider 12). During this process, if the relative position between the third slider 92 and the second base 91 attempts to exceed the predetermined movement range, the third slider 92 will come into contact with the limiting member 912 on either side. Once the contact occurs, the limiting member 912 will prevent the third slider 92 and the second base 91 from continuing to move, thereby restricting them within the predetermined range.

[0097] In one example, as Figures 1 to 6 shown, for the convenience of installing the door panel 3, the first driven sliding door component 9 further includes: a first hanging bracket 94. The first hanging bracket 94 is connected to the outside of the second base 91 and is used for hanging the door panel 3.

[0098] In this embodiment, the first hanging bracket 94 serves as the hanging point for the door panel 3, making the installation of the door panel 3 simpler and faster because the installer only needs to hang the door panel 3 on the first hanging bracket 94 without performing complex fixing or connecting operations. The first hanging bracket 94 is provided with a connection structure that matches the outside of the second base 91 to ensure that it can be firmly connected to the second base 91. This connection structure can be a bolt connection, welding, or other reliable connection methods. At the same time, the first hanging bracket 94 is provided with hanging points suitable for hanging the door panel 3 to bear the weight of the door panel 3 and the forces generated during the sliding process.

[0099] During the installation process, the installer will first firmly connect the first hanging bracket 94 to the outside of the second base 91. Then, they will hang or connect the corresponding part of the door panel 3 to the first hanging bracket 94. Since the connection between the first hanging bracket 94 and the second base 91 is firm, the door panel 3 will also maintain a stable connection state with the second base 91 through the first hanging bracket 94.

[0100] In an embodiment of the present application, a door body assembly is provided, as Figures 1 to 3As shown, the door assembly includes: a box door 2, a door panel 3 and a sliding door device. The box door 2 is rotatably connected to the box body 4, and the box door 2 is suitable for opening or closing the storage space of the box body 4. The door panel 3 is slidably arranged on the outside of the box door 2. The structure of the sliding door device can be referred to the above embodiment, and will not be repeated here.

[0101] In the door assembly provided in this embodiment, during the process of opening or closing the door 2, the box body 4 drives the active sliding door component 1 through the traction component 17. The active sliding door component 1 drives the first driven sliding door component 9, so as to drive the door panel 3 to move relative to the width direction of the door 2 through the first driven sliding door component 9, thereby avoiding interference between the door panel 3 and obstacles outside. In this process, the active sliding door component 1 that directly bears the driving force does not bear the weight of the door panel 3, while the first driven sliding door component 9 connected to the door panel 3 bears the weight of the entire door panel 3, so that during the process of opening or closing the door 2, the active sliding door component 1 can be prevented from being subjected to external forces in other directions.

[0102] According to the door assembly provided in the embodiment, a sliding door device including a traction component 17, an active sliding door component 1, and a first driven sliding door component 9 is set on the box door 2, and the active sliding door component 1 is connected to the box body 4 through the traction component 17, and the first driven sliding door component 9 is connected to the active sliding door component 1, so that the box body 4 drives the active sliding door component 1 through the traction component 17, and the active sliding door component 1 drives the first driven sliding door component 9, and the door panel 3 is driven to move relative to the width direction of the box door 2 through the first driven sliding door component 9, so that the door panel 3 avoids obstacles on both sides and solves the interference problem in the door opening process. At the same time, the active sliding door component 1 that directly bears the driving force of the sliding door device does not bear the weight of the door panel 3, and the first driven sliding door component 9 connected to the door panel 3 bears the weight of the entire door panel 3, so that in the process of opening or closing the box door 2, the active sliding door component 1 can be prevented from being subjected to external forces in other directions, and the problem of shaking of the door panel 3 when moving relative to the box door 2 is reduced.

[0103] In some embodiments, Figures 1 to 3 As shown, the sliding door device is arranged at the top end of the box door 2, and the door body assembly also includes: a second driven sliding door component 18, the second driven sliding door component 18 is arranged at the bottom end of the box door 2, and the second driven sliding door component 18 is connected to the door panel 3. During the opening or closing process of the box door 2, the second driven sliding door component 18 cooperates with the first driven sliding door component 9 to guide the door panel 3 to move relative to the width direction of the box door 2.

[0104] Specifically, in this embodiment, the traction component 17, the active sliding door component 1, and the first driven sliding door component 9 are arranged at the top end of the box door 2. The second driven sliding door component 18 is arranged at the bottom end of the box door 2. During the opening or closing process of the box door 2, the box body 4 drives the active sliding door component 1 through the traction component 17. The active sliding door component 1 drives the first driven sliding door component 9 to drive the door panel 3 to move relative to the width direction of the box door 2 through the first driven sliding door component 9, thereby avoiding interference between the door panel 3 and external obstacles. During this process, the second driven sliding door component 18 cooperates with the first driven sliding door component 9 to guide the door panel 3 to move relative to the width direction of the box door 2, which can effectively improve the stability during movement.

[0105] In this embodiment, through the coordinated work of the active sliding door component 1, the first driven sliding door component 9, and the second driven sliding door component 18, the movement direction of the door panel 3 can be effectively restricted. The door panel 3 will move along a predetermined trajectory during the sliding process, avoiding the shaking and instability phenomena caused by direction deviation. This restrictive effect ensures the stability of the door panel 3.

[0106] To facilitate the installation of the sliding door device, a first end cover 21 is provided at the top end of the box door 2. An installation groove for installing the traction component 17, the active sliding door component 1, and the first driven sliding door component 9 is provided on the first end cover 21. According to the specific shapes of the traction component 17, the active sliding door component 1, and the first driven sliding door component 9, the position and shape of the installation groove can be adjusted to meet different installation requirements. Similarly, a second end cover 22 is provided at the bottom end of the box door 2. An installation groove for installing the second driven sliding door component 18 is provided on the second end cover 22. According to the shape of the second driven sliding door component 18 and the position where the door panel 3 needs to be connected, the position and shape of the installation groove can be adjusted to meet different installation requirements.

[0107] In one embodiment, as Figure 7 shown, the second driven sliding door component 18 is a C-shaped drawer track structure, including: a third base 181 and a fourth slider 182. A fourth guide rail 1811 is formed inside the third base 181, and the third base 181 is connected to the door panel 3. The fourth slider 182 is slidably arranged (generally inscribed) in the fourth guide rail 1811, and the fourth slider 182 is connected to the box door 2; a second hanger 183 is connected to the outside of the third base 181 for hanging the door panel 3.

[0108] In this embodiment, the fourth guide rail 1811 is provided inside the third base 181, the fourth slider 182 is connected to the box door 2, and the outside of the third base 181 is connected to the door panel 3 through the second hanger 183. When the door panel 3 moves relative to the box door 2, the third base 181 moves relative to the fourth slider 182 through the fourth guide rail 1811, so as to be able to cooperate with guiding the movement of the door panel 3 and the box door 2.

[0109] In one embodiment, as Figure 7 shown, the second driven sliding door component 18 further includes: a second hanging bracket 183. The second hanging bracket 183 is connected to the outside of the third base 181 and is used for hanging the door panel 3.

[0110] In this embodiment, the second hanging bracket 183 is the same as the first hanging bracket 94 and also serves as the hanging point of the door panel 3, making the installation of the door panel 3 simpler and faster because the installer only needs to hang the door panel 3 on the first hanging bracket 94 and the second hanging bracket 183 without complex fixing or connecting operations.

[0111] During the installation process, the installer will first firmly connect the first hanging bracket 94 and the second hanging bracket 183 to the outside of the second base 91 and the third base 181. Then, they will hang or connect the corresponding parts of the door panel 3 to the first hanging bracket 94 and the second hanging bracket 183. Since the connection between the first hanging bracket 94 and the second base 91 and the connection between the second hanging bracket 183 and the third base 181 are firm, the door panel 3 will also maintain a stable connection state through the first hanging bracket 94 and the second hanging bracket 183.

[0112] Similarly, the second driven sliding door component 18 further includes a second ball support member 184. The second ball support member 184 is slidably internally connected to the fourth guide rail 1811, and the fourth slider 182 is slidably internally connected to the second ball support member 184. With the assistance of the second ball support member 184, the fourth slider 182 slides in the fourth guide rail 1811 with low friction and high efficiency. Due to the presence of the second ball support member 184, the sliding process of the fourth slider 182 becomes smoother and more reliable, thus ensuring the stable operation of the entire second driven sliding door component 18. It should be noted that the specific structure of the second ball support member 184 is the same as that of the first ball support member 93 and will not be elaborated here.

[0113] It should be noted that in practical applications, the designs of the first slider 11, the second slider 12, the third slider 92, and the fourth slider 182 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.

[0114] From the perspective of materials, the first slider 11, the second slider 12, the third slider 92, and the fourth slider 182 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 sliders, reduce wear and noise during the sliding process, and ensure the smoothness of the sliding.

[0115] In terms of structural design, the first slider 11, the second slider 12, the third slider 92, and the fourth slider 182 can adopt various forms of guide rail contact surfaces, such as planar contact, ball contact, or sliding bearing contact, etc. These different contact methods have their own advantages and disadvantages. For example, ball contact can reduce friction and wear, but the cost is relatively high; while planar contact has a simple structure, but may require more frequent lubrication and maintenance. Therefore, when making a choice, factors such as usage conditions, cost-effectiveness, and maintenance convenience should be comprehensively considered.

[0116] In an embodiment of another aspect of the present application, as Figures 1 to 9 shown, a refrigeration device is provided, including: a box body 4 and a door body 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. The structure of the door body assembly can refer to the above embodiments and will not be elaborated here.

[0117] By providing a door panel 3 on the box door 2, when the refrigeration device is an inlaid type and is arranged in a groove-shaped space, or is arranged 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.

[0118] At the same time, when the box door 2 rotates, the active sliding door component 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 as possible away from obstacles such as the wall or cabinet on 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.

[0119] The combination of the box 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 usage convenience. Especially in a narrow kitchen environment, this design advantage is more obvious. In addition, the setting of the inner slider and guide rail in the active sliding door component 1 enables the door panel 3 to move smoothly during the opening and closing processes, improving the service life and stability of the refrigerator.

[0120] It can be understood that if the door body assembly has the beneficial effects of the above embodiments, then the refrigeration device correspondingly has the beneficial effects of the above embodiments. The specific implementation manners can refer to the above embodiments and will not be elaborated in this application.

[0121] In some embodiments, as Figure 8 and Figure 9As shown, the door body assembly and the box body 4 are configured to be disposed within 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 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 active sliding door component 1 is configured to drive the door panel 3 on the box door 2 to move a preset distance in a direction away from or towards 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.

[0122] During the process of the box door 2 passing through the opening to control the opening or closing of the storage space, the active sliding door component 1 is configured to drive the door panel 3 on the box door 2 to move a preset distance in a direction away from or towards the hinge 5. In order to avoid interference between the door panel 3 and the side walls of the first cabinet body 6 and the second cabinet body 7, and in order to enable the door panel 3 to smoothly open or close through the movement of the preset distance without colliding with or jamming against the side walls of the cabinet body.

[0123] For example, as Figure 8 and Figure 9 shown, during the opening process of the box door 2, the active sliding door component 1 drives the door panel 3 along the box door 2 in a direction away from the hinge 5 by a preset distance. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet body 7, enabling the box door 2 to be fully opened, facilitating users to access items.

[0124] Similarly, during the closing process of the box door 2, the active sliding door component 1 drives the door panel 3 along the box door 2 in a direction towards the hinge 5 by a preset distance. In this way, the door panel 3 can smoothly avoid the side wall of the first cabinet body 6, enabling the box door 2 to be fully closed, maintaining the overall aesthetics and sealing performance.

[0125] In some embodiments, as Figure 1 and Figure 2 shown, the box body 4 is formed with at least two storage spaces, and there are multiple door body assemblies. Each door body assembly corresponds to one of the storage spaces, so that during the opening or closing process of any box door 2, the door panel 3 is driven to move relative to the corresponding box door 2.

[0126] In the present application, the box body 4 has at least two storage spaces, and the two storage spaces can be set to different storage environments (different temperatures, humidities, etc.) to meet the storage conditions of different items. Each storage space is provided with a corresponding door body assembly, and the box door 2 of the corresponding door body assembly can open or close the corresponding storage space, enabling the two storage spaces to be independently opened or closed, facilitating users to store or retrieve items in the storage space. The door panel 3 of each door body assembly can also slide relative to the corresponding box door 2. When the box door 2 is closed, the door panel 3 can be flush with the side cabinet, or when the box door 2 is opened, the door panel 3 can avoid the obstacles on both sides.

[0127] Specifically, the box body 4 has a first storage space and a second storage space. Correspondingly, the door body assembly also includes a first door body assembly and a second door body assembly. The box door 2 of the first door body assembly is rotatably connected to the box body 4 to open or close the first storage space, and the box door 2 of the second door body assembly is rotatably connected to the box body 4 to open or close the second storage space.

[0128] Furthermore, the first door body assembly and the second door body assembly are arranged up and down along the height direction of the box door 2. The first door body assembly is provided with an active sliding door component 1, a first driven sliding door component 9, and a second driven sliding door component 18. The corresponding door panel 3 and the box door 2 can be controlled to move correspondingly by using the corresponding active sliding door component 1, first driven sliding door component 9, and second driven sliding door component 18. The second door body assembly is provided with an active sliding door component 1, a first driven sliding door component 9, and a second driven sliding door component 18. The corresponding door panel 3 and the box door 2 can be controlled to move correspondingly by using the corresponding active sliding door component 1, first driven sliding door component 9, and second driven sliding door component 18.

[0129] 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 by the scope of the claims of the present invention.
