[0073] The sliding door device, door assembly, and refrigeration device of the present application are described below with reference to Figures 1 to 9. The sliding door device and door assembly of the present application can be applied to a door 2 or cabinet door of a household appliance, such as a refrigerator door 2. However, it should be understood that the door assembly of the present application can also be applied to any other suitable device. The refrigeration device of the present application is applied to a refrigerator, for example, but it should be understood that the refrigeration device of the present application can also be applied to a freezer or any other suitable device.

[0074] In one embodiment of the present application, as shown in Figures 1 to 3, the sliding door device is applied to a refrigeration device, which 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 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.

[0075] In this embodiment, the sliding door device includes: a traction component 17, an active sliding door component 1, and a first driven sliding door component 9. The active sliding door component 1 is disposed on the compartment door 2 and is transmission-connected to the compartment body 4 via the traction component 17. The first driven sliding door component 9 is disposed on the compartment door 2 and is transmission-connected to the active sliding door component 1. The first driven sliding door component 9 and / or the active sliding door component 1 are connected to the door panel 3. During the process of opening or closing the compartment door 2, the compartment body 4 drives the active sliding door component 1 via the traction component 17, and the active sliding door component 1 drives the first driven sliding door component 9. The first driven sliding door component 9 cooperates with the active sliding door component 1 to drive the door panel 3 to move in the width direction relative to the compartment door 2.

[0076] In this embodiment, the housing 4 serves as the main body of the refrigeration unit. It contains a storage space for food or other items requiring refrigeration or freezing. A door 2 is attached to the housing 4 via a rotating connection (e.g., hinge 5) and can rotate about one or more pivot points to open and close the storage space. A door panel 3, an additional, slidable component, is provided on the outside of the door 2.

[0077] In this embodiment, a traction member 17 (such as a chain, belt, or wire rope) connects the housing 4 to the active sliding door member 1. When the door 2 opens or closes, the movement of the traction member 17 transmits power to the active sliding door member 1. The active sliding door member 1 does not directly bear the weight of the door panel 3. Instead, it serves as the key to transmitting power, converting the power from the traction member 17 into drive for the first driven sliding door member 9. The first driven sliding door member 9 closely mates with the active sliding door member 1, directly connecting to and driving the movement of the door panel 3.

[0078] When the door panel 3 is connected only by the first driven sliding door component 9, since the first driven sliding door component 9 bears the weight of the entire door panel 3, the design of the first driven sliding door component 9 needs to balance strength and flexibility to ensure the smooth sliding of the door panel 3. During the opening or closing process of the door 2, the housing 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 door 2 through the first driven sliding door component 9, thereby preventing the door panel 3 from interfering with external obstacles. During this process, the active sliding door component 1, which 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. This prevents the active sliding door component 1 from being subjected to external forces in other directions during the opening or closing process of the door 2, thereby reducing the problem of the door panel 3 shaking when moving relative to the door 2.

[0079] When the door panel 3 is connected to the first driven sliding door component 9 and the active sliding door component 1 at the same time, the weight of the door panel 3 is borne jointly by the first driven sliding door component 9 and the active sliding door component 1, which reduces the gravity borne by the active sliding door component 1 and alleviates the shaking of the door panel 3 when it moves relative to the box door 2 to a certain extent. At the same time, since the active sliding door component 1 is connected to the door panel 3, the sensitivity of the entire sliding door device can be increased.

[0080] In the case where the door panels are connected only through the active sliding door component 1 , the door panel 3 is carried by the active sliding door component 1 , and the active sliding door component 1 can be used to drive the door panel 3 to move.

[0081] According to the sliding door device of 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 provided on the box door 2. The active sliding door component 1 is transmission-connected to the box body 4 through the traction component 17, and the first driven sliding door component 9 is transmission-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 by the first driven sliding door component 9 to move relative to the width direction of the box door 2, so that the door panel 3 avoids obstacles on both sides and solves the interference problem during the door opening process. At the same time, when only the first driven sliding door component 9 is used to connect the door panel 3, the active sliding door component 1 does not directly bear the weight of the door panel 3, so that when the box door 2 is opened or closed, the active sliding door component 1 can be prevented from being subjected to external forces in other directions, thereby reducing the problem of shaking of the door panel 3 when it moves relative to the box door 2.

[0082] In some embodiments, as shown in Figure 4, 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 disposed on the first guide rail 131 and is connected to the housing 4 via a traction member 17. The second slider 12 is slidably disposed on the second guide rail 132 and is in transmission connection with the first driven sliding door component 9. The flexible cable 14 is connected to the first slider 11 and the second slider 12 at both ends. When the housing 4 drives the first slider 11 to move on the first guide rail 131 via the traction member 17, the first slider 11 drives the second slider 12 to move in the opposite direction on the second guide rail 132 via the flexible cable 14.

[0083] In this embodiment, the first base 13 is fixed to the box door 2, and a first guide rail 131 and a second guide rail 132 are formed on the inner and outer sides thereof, respectively. The first guide rail 131 and the second guide rail 132 provide tracks for the sliding of the first slider 11 and the second slider 12, respectively. The first slider 11 is slidably mounted on the first guide rail 131, connected to the box body 4 through the traction component 17, and is driven by the box body 4 to move on the first guide rail 131. The second slider 12 is also slidably mounted on the second guide rail 132, but is connected to the first driven sliding door component 9 to drive the first driven sliding door component 9. The flexible cable 14 can be a connecting component 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, so that the two move in opposite directions. This design ensures that when the door panel 3 slides along the width direction of the box body 4, the first slider 11 and the second slider 12 only bear the driving force of the traction component 17, and do not need to bear the weight of the door panel 3 in the vertical direction. The weight of the entire door panel 3 is only carried by the first driven sliding door component 9, thereby reducing the problem of shaking of the door panel 3 when moving relative to the box door 2.

[0084] During the process of rotating the door 2 toward the outside of the housing 4 to open, the housing 4 drives the first slider 11 to slide toward the hinge 5 via the traction member 17. At the same time, the first slider 11 drives the second slider 12 to slide in the opposite direction via the flexible cable 14. The second slider 12 drives the first driven sliding door member 9, which in turn drives the door panel 3 to move, thereby preventing the door panel 3 from interfering with obstacles on the outside. During the process of rotating the door 2 toward the side of the housing 4 to close, the housing 4 drives the first slider 11 to slide away from the hinge 5 via the traction member 17. At the same time, the first slider 11 drives the second slider 12 to slide in the opposite direction via the flexible cable 14. The second slider 12 drives the first driven sliding door member 9, which in turn drives the door panel 3 to move, thereby preventing the door panel 3 from interfering with obstacles after closing.

[0085] In some embodiments, as shown in FIG4 , the flexible cable 14 includes a first flexible cable and a second flexible cable. The first flexible cable passes around the first end of the first base 13 and is connected to the first ends of the first slider 11 and the second slider 12 at both ends. The second flexible cable passes around the second end of the first base 13 and is connected to the second ends of the first slider 11 and the second slider 12 at both ends.

[0086] When the first slider 11 is moved toward the first end of the first base 13, the second slider 12 is driven by the first driven sliding door component 9 to slide relative to the first slider 11 when the first slider 11 is opened and closed, so as to avoid interference with obstacles and affecting the opening and closing of the door 2.

[0087] In some embodiments, as shown in FIG4 , 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 a first end of the first base 13 and is formed with a first limiting groove. The first limiting groove has two ends that abut the first ends of the first guide rail 131 and the second guide rail 132, and a portion of the first flexible cable is slidably disposed in the first limiting groove. The second fixing seat 16 is connected to a second end of the first base 13 and is formed with a second limiting groove. The second limiting groove has two ends that abut the second ends of the first guide rail 131 and the second guide rail 132, and a portion of the second flexible cable is slidably disposed in the second limiting groove.

[0088] Specifically, the first fixed seat 15 is connected to the first 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 fixed 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. The two ends of the first limiting groove are connected to the first ends of the first guide rail 131 and the second guide rail 132. The presence of the first limiting groove limits the deviation and shaking of the first flexible cable during the sliding process, thereby improving the operating accuracy and reliability of the entire active sliding door component 1. The second fixed seat 16 corresponds to the first fixed seat 15. The second fixed seat 16 is connected to the second 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 fixed seat 16. Its design is similar to that of the first limiting groove, but it is located at the second end of the active sliding door component 1. The two ends of the second limiting groove are connected to the second ends of the first guide rail 131 and the second guide rail 132, providing guidance and limiting for the sliding of the second flexible cable. The second limiting groove is the same as the first limiting groove, and the second limiting groove also plays a role in limiting the deviation and shaking of the flexible cable 14.

[0089] In order to achieve the installation of the active sliding slider mechanism, in some embodiments, as shown in Figure 4, a fixing hole is provided on the first fixing seat 15 and / or the second fixing seat 16, and the active sliding door component 1 also includes a fixing piece, which passes through the fixing hole 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.

[0090] In this embodiment, the first fixing seat 15 and / or the second fixing seat 16 connected to the first base 13 are fixed to the box door 2 by fixing parts, which can ensure that the mechanism will not loosen or shift due to external force or vibration during operation. The design of the fixing holes and fixing parts makes the installation process simple and quick. The operator only needs to align the fixing parts with the fixing holes and tighten them to complete the connection between the active sliding door component 1 and the box door 2. When the active sliding door component 1 needs to be repaired or replaced, the active sliding door component 1 can be removed from the box door 2 by simply removing the fixing parts without the need for complicated disassembly work. This greatly improves the maintainability and flexibility of the equipment.

[0091] During specific implementation, suitable fixings, such as screws, bolts, rivets, etc., can be selected according to the structure and material of the door 2. At the same time, it is also necessary to ensure that the position and size of the fixing holes match the fixings to ensure the firmness and stability of the connection.

[0092] In some embodiments, as shown in Figures 4, 5, and 6, the first driven sliding door component 9 is a C-shaped drawer track structure, comprising a second base 91 and a third slider 92. The second base 91 is connected to the second slider 12 via a fixing plate 95 on its inner side and to the door panel 3 on its outer side. A third guide rail 911 is formed within the second base 91. The third slider 92 is slidably disposed within the third guide rail 911 and is connected to the 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 within the third guide rail 911.

[0093] In this embodiment, the second base 91 is connected to the second slider 12 on its inner side, 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 second base 91 is designed with a third guide rail 911 inside to accommodate and guide 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 door 2 (or may be a part of the door). This means that when the third slider 92 moves in the third guide rail 911, the relative movement of the second base 91 and the third slider 92 causes the door panel 3 and the door 2 to move relative to each other.

[0094] When the second slider 12 moves along the second guide rail 132, the second base 91 also moves because the inner side of the second base 91 is connected to the second slider 12. During this process, because the third slider 92 is fixed to the door 2 and slidably disposed in the third guide rail 911 of the second base 91, when the second base 91 moves, it drives the door panel 3 to move accordingly through the relative movement between the third guide rail 911 and the third slider 92.

[0095] In some embodiments, as shown in Figures 4 to 6, the first driven sliding door component 9 further includes a first ball bearing support. The first ball bearing support 93 is slidably inscribed in the third guide rail 911, and the third slider 92 is slidably inscribed in the first ball bearing support 93. When the second slider 12 moves on the second guide rail 132, it drives the second base 91 to move via a connecting member (such as a rod, chain, etc.) or directly. As the second base 91 moves, the third slider 92 moves relative to it. At this time, the third slider 92, assisted by the first ball bearing support 93, slides in the third guide rail 911 with low friction and high efficiency. Due to the presence of the first ball bearing support 93, the sliding process of the third slider 92 becomes smoother and more reliable, thereby ensuring the stable operation of the entire first driven sliding door component 9.

[0096] Specifically, the first ball support member 93 includes a support frame and a ball (not shown). The support frame is disposed between the third guide rail 911 and the third slider 92, and a limiting notch is formed in the support frame. The ball is rollably disposed in the limiting notch, with one side of the ball abutting the third guide rail 911 and the other side of the ball passing through the limiting notch and abutting the third slider 92.

[0097] In this embodiment, a support frame is positioned between the third guide rail 911 and the third slider 92. It ensures that the balls can roll in the correct position, thereby supporting the sliding movement of the third slider 92. A limiting notch is designed in the support frame to accommodate the balls and limit their rolling range. The limiting notch ensures that the balls do not escape from the support frame during rolling, while also providing sufficient rolling space for the balls. The balls are rollably positioned in the limiting notch, with one side contacting the third guide rail 911 and the other side passing through the limiting notch to contact the third slider 92. This design eliminates the need for direct contact with the third guide rail 911 and friction, allowing the third slider 92 to slide. Instead, the sliding motion is achieved through the rolling motion of the balls. This significantly reduces frictional resistance during sliding, improving sliding efficiency. Because the rolling motion of the balls is low-friction, it significantly reduces wear between the third slider 92 and the third guide rail 911. This helps extend the service life of both components and reduces maintenance costs.

[0098] 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 (e.g., from the second slider 12). During this process, the second base 91 pushes the ball bearings to roll within the retaining notches of the support frame. One side of the ball bearings maintains contact and rolls with the third guide rail 911, while the other side maintains contact and rolls with the third slider 92. In this way, the first ball bearing support 93 provides stable and efficient support for the sliding movement of the third slider 92.

[0099] In summary, the first ball support member 93 in this embodiment achieves 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, thereby effectively improving the sliding efficiency.

[0100] In addition, as shown in Figures 5 and 6, the third guide rail 911 is provided with limit members 912, which are located on both sides of the third slider 92. When the third slider 92 moves within the third guide rail 911, the contact between the limit members 912 and the third slider 92 limits the range of movement of the third slider 92. The limit members 912 should be precisely installed at appropriate positions on the third guide rail 911 to ensure that they can effectively limit the range of movement of the third slider 92. Generally, the position of the limit members 912 is determined according to the movement requirements of the door panel 3 and the box door 2. The shape and size of the limit members 912 should be determined according to the contour and movement of the third slider 92 to withstand the impact force generated by the third slider 92 when in contact and maintain a stable limiting effect.

[0101] During operation, as the third slider 92 moves within the third guide rail 911, the second base 91 slides in response to an external driving force (e.g., a driving force from the second slider 12). During this process, if the third slider 92 attempts to move beyond the predetermined range of relative movement relative to the second base 91, the third slider 92 will come into contact with a stopper 912 on either side. Once contact occurs, the stopper 912 prevents further movement of the third slider 92 and the second base 91, thereby confining them to the predetermined range.

[0102] In one example, as shown in FIG1 to FIG6 , to facilitate installation of 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 outer side of the second base 91 and is used to hang the door panel 3 .

[0103] In this embodiment, the first bracket 94 serves as the attachment point for the door panel 3, making installation of the door panel 3 simpler and faster. Installers only need to attach the door panel 3 to the first bracket 94, eliminating the need for complex fixing or connecting operations. The first bracket 94 features a connection structure that mates with the exterior of the second base 91, ensuring a secure connection to the second base 91. This connection structure can be bolted, welded, or otherwise reliable. Furthermore, the first bracket 94 is equipped with attachment points suitable for attaching the door panel 3 to withstand the weight of the door panel 3 and the forces generated during sliding.

[0104] During installation, the installer will first securely attach the first hanger 94 to the outside of the second base 91. They will then hook or connect the corresponding portion of the door panel 3 to the first hanger 94. Since the connection between the first hanger 94 and the second base 91 is secure, the door panel 3 will also remain stably connected to the second base 91 via the first hanger 94.

[0105] In some embodiments, as shown in Figures 1 to 5, a fixing plate 95 for connecting the door panel 3 is provided on the first driven sliding door component 9, and the active sliding door component 1 is connected to the fixing plate 95, that is, the first driven sliding door component 9 and the active sliding door component 1 simultaneously support the door panel 3 through the fixing plate 95. At this time, the first driven sliding door component 9 and the active sliding door component 1 simultaneously drive the door panel 3 to move relative to the width direction of the box door 2.

[0106] Since the weight of the door panel 3 is jointly borne by the first driven sliding door component 9 and the active sliding door component 1, the gravity borne by the active sliding door component 1 is reduced, which to a certain extent alleviates the shaking of the door panel 3 when it moves relative to the box door 2. At the same time, since the active sliding door component 1 is connected to the door panel 3, the sensitivity of the entire sliding door device can be increased.

[0107] In this embodiment, since the weight of the door panel 3 is shared by the two sliding door components, the gravity that the active sliding door component 1 alone bears is reduced, which helps to extend its service life.

[0108] Due to the distribution of gravity, the sway of the door panel 3 during movement is also reduced, improving the stability and reliability of the sliding door device. In addition, because the active sliding door component 1 is directly connected to the door panel 3, it can more directly sense the movement requirements of the door panel 3, thereby responding more quickly and increasing the sensitivity of the entire sliding door device.

[0109] In other embodiments, as shown in Figures 1 to 5, a fixing plate 95 for connecting the door panel 3 is provided on the first driven sliding door component 9, and the active sliding door component 1 is separated from the fixing plate 95, that is, the door panel 3 is only connected through the first driven sliding door component 9 at this time, so that the active sliding door component 1 indirectly drives the door panel 3 to move relative to the width direction of the box door 2 through the first driven sliding door component 9.

[0110] Since the active sliding door component 1 that directly bears the driving force 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, during 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, thereby reducing the problem of shaking of the door panel 3 when moving relative to the box door 2.

[0111] In this embodiment, since the active sliding door component 1 does not bear the weight of the door panel 3, it can focus on providing a smooth driving force, avoiding interference from the weight of the door panel 3 or external forces from other directions. In addition, the first driven sliding door component 9 bears the weight of the door panel 3 independently, allowing it to more conveniently adjust according to the actual weight and movement of the door panel 3, thereby more effectively reducing the shaking of the door panel 3 during movement.

[0112] In one embodiment of the present application, a door assembly is provided, as shown in Figures 1 to 3 . The door assembly comprises a door 2, a door panel 3, and a sliding door assembly. The door 2 is pivotally connected to a container 4 and is adapted to open or close the storage space within the container 4. The door panel 3 is slidably disposed outside the door 2. The structure of the sliding door assembly can be found in the above-described embodiments and will not be further described here.

[0113] In the door assembly provided in this embodiment, during the opening or closing of the door 2, the housing 4 drives the active sliding door component 1 via the traction component 17. The active sliding door component 1 drives the first driven sliding door component 9, which in turn drives the door panel 3 to move in the width direction relative to the door 2, thereby preventing the door panel 3 from interfering with external obstacles. During this process, the active sliding door component 1, which directly bears the driving force, may not bear the weight of the door panel 3, depending on the specific configuration. Instead, the first driven sliding door component 9, connected to the door panel 3, bears the entire weight of the door panel 3. This prevents the active sliding door component 1 from being subjected to external forces in other directions during the opening or closing of the door 2.

[0114] According to the door body 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 transmission-connected to the box body 4 through the traction component 17, and the first driven sliding door component 9 is transmission-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, thereby solving the interference problem during the door opening process.

[0115] In some embodiments, as shown in Figures 1 to 3, 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.

[0116] Specifically, in this embodiment, the traction component 17, the active sliding door component 1, and the first driven sliding door component 9 are disposed at the top end of the door 2. The second driven sliding door component 18 is disposed at the bottom end of the door 2. During the opening or closing process of the door 2, the housing 4 drives the active sliding door component 1 via the traction component 17. The active sliding door component 1 drives the first driven sliding door component 9, which in turn drives the door panel 3 to move relative to the width of the door 2 via the first driven sliding door component 9, thereby preventing 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 movement of the door panel 3 relative to the width of the door 2, effectively improving stability during movement.

[0117] In this embodiment, the active sliding door component 1, the first driven sliding door component 9, and the second driven sliding door component 18 work together to effectively restrict the movement direction of the door panel 3. This ensures that the door panel 3 moves along a predetermined trajectory during the sliding process, avoiding shaking and instability caused by directional deviation. This restrictive effect ensures the stability of the door panel 3.

[0118] To facilitate the installation of the sliding door assembly, the top end of the door 2 is provided with a first end cap 21. This first end cap 21 is provided with mounting slots for accommodating the traction member 17, the active sliding door member 1, and the first driven sliding door member 9. The position and shape of these mounting slots can be adjusted to suit different installation requirements, depending on the specific shapes of the traction member 17, the active sliding door member 1, and the first driven sliding door member 9. Similarly, the bottom end of the door 2 is provided with a second end cap 22. This second end cap 22 is provided with a mounting slot for accommodating the second driven sliding door member 18. The position and shape of these mounting slots can be adjusted to suit different installation requirements, depending on the shape of the second driven sliding door member 18 and the location where the door panel 3 needs to be connected.

[0119] In one embodiment, as shown in Figure 7 , the second driven sliding door component 18 is a C-shaped drawer track structure, comprising a third base 181 and a fourth slider 182 . A fourth guide rail 1811 is formed within the third base 181 and is connected to the door panel 3 . The fourth slider 182 is slidably disposed within (generally internally connected to) the fourth guide rail 1811 and is connected to the door 2 . A second hanger 183 is connected to the outside of the third base 181 for attaching the door panel 3 .

[0120] In this embodiment, the third base 181 is provided with a fourth guide rail 1811 on its inner side, the fourth slider 182 is connected to the box door 2, and the outer side of the third base 181 is connected to the door panel 3 through the second bracket 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 that it can cooperate to guide the movement of the door panel 3 and the box door 2.

[0121] In one embodiment, as shown in FIG7 , the second driven sliding door component 18 further includes a second hanging bracket 183 . The second hanging bracket 183 is connected to the outer side of the third base 181 and is used for hanging the door panel 3 .

[0122] In this embodiment, the second bracket 183 is the same as the first bracket 94 and also serves as a 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 bracket 94 and the second bracket 183 without the need for complicated fixing or connecting operations.

[0123] During installation, the installer will first securely attach the first and second hangers 94, 183 to the outsides of the second and third bases 91, 181. They will then hook or connect the corresponding portions of the door panel 3 to the first and second hangers 94, 183. Because the connections between the first hanger 94 and the second base 91, and the second hanger 183 and the third base 181, are secure, the door panel 3 will also remain securely connected via the first and second hangers 94, 183.

[0124] Similarly, the second driven sliding door component 18 also includes a second ball bearing support 184. The second ball bearing support 184 is slidably inscribed within the fourth guide rail 1811, and the fourth slider 182 is slidably inscribed within the second ball bearing support 184. Assisted by the second ball bearing support 184, the fourth slider 182 slides within the fourth guide rail 1811 with low friction and high efficiency. The presence of the second ball bearing support 184 makes the sliding of the fourth slider 182 smoother and more reliable, thereby ensuring stable operation of the entire second driven sliding door component 18. It should be noted that the specific structure of the second ball bearing support 184 is identical to that of the first ball bearing support 93 and will not be further described here.

[0125] It should be noted that, in actual 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 adaptable to different working scenarios and performance requirements. They are not limited to specific shapes, sizes, or materials and can be customized and optimized according to specific needs.

[0126] From a material perspective, 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 lubricants. These materials are selected to improve the durability of the sliders, reduce wear and noise during sliding, and ensure smooth sliding.

[0127] In terms of structural design, the first slider 11, the second slider 12, the third slider 92, and the fourth slider 182 can utilize various guide rail contact surfaces, such as flat contact, ball contact, or sliding bearing contact. Each of these contact methods has its own advantages and disadvantages. For example, ball contact reduces friction and wear, but is more expensive; flat contact, on the other hand, offers a simpler structure but may require more frequent lubrication and maintenance. Therefore, when selecting a suitable contact method, factors such as usage conditions, cost-effectiveness, and ease of maintenance should be comprehensively considered.

[0128] In another embodiment of the present application, as shown in Figures 1 to 9 , a refrigeration appliance is provided, comprising: a housing 4 and a door assembly as provided in any of the above embodiments. The housing 4 defines a storage space, and the door 2 is rotatably connected to the housing 4, adapted to open and close the storage space. The structure of the door assembly can be found in the above embodiments and will not be further described here.

[0129] By setting a door panel 3 on the cabinet door 2, when the refrigeration equipment is embedded and set in a groove-shaped space, or when it is set between two cabinets, the door panel 3 can be set flush with the cabinets on the side walls or both sides of the groove to reduce the gap between the refrigeration equipment and the adjacent wall or cabinet, making it more beautiful.

[0130] 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 stay as far away as possible from obstacles such as the wall or cabinet of the side door of the box body 4, so as to avoid these obstacles blocking the door panel 3 and affecting the rotation of the box door 2, causing the box door 2 to be unable to open or close normally.

[0131] The combination of door 2 and door panel 3 prevents interference between the door panel 3 and surrounding objects during opening and closing, significantly improving ease of use. This design advantage is particularly evident in cramped kitchen environments. Furthermore, the sliders and guide rails within the active sliding door assembly 1 ensure smooth movement of the door panel 3 during opening and closing, extending the refrigerator's lifespan and stability.

[0132] It can be understood that if the door assembly has the beneficial effects of the above embodiments, then the refrigeration equipment will correspondingly have the beneficial effects of the above embodiments. Its specific implementation can refer to the above embodiments, and this application will not elaborate on them.

[0133] In some embodiments, as shown in Figures 8 and 9, the door assembly and cabinet 4 are arranged within an installation space 8 formed between a first cabinet 6 and a second cabinet 7. An opening is provided on the outside of the installation space 8. This design allows the door assembly and cabinet 4 to be integrally embedded within the cabinet. When the cabinet door 2 passes 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 cabinet door 2 to move a predetermined distance away from or toward the hinge 5, so that the door panel 3 clears the side walls of the first cabinet 6 and the second cabinet 7.

[0134] As the door 2 passes 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 to move a predetermined distance on the door 2 in a direction away from or toward the hinge 5. To prevent the door panel 3 from interfering with the side walls of the first cabinet 6 and the second cabinet 7, the door panel 3 can be opened or closed smoothly through the predetermined movement without colliding or getting stuck with the cabinet side walls.

[0135] For example, as shown in Figures 8 and 9, when the door 2 is opened, the active sliding door component 1 drives the door panel 3 to move a preset distance along the 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 7, allowing the door 2 to be fully opened, making it convenient for the user to store and retrieve items.

[0136] Similarly, when the door 2 is closing, the active sliding door component 1 drives the door panel 3 to move a preset distance along the door 2 toward the hinge 5. In this way, the door panel 3 can smoothly avoid the side wall of the first cabinet 6, allowing the door 2 to be completely closed, maintaining the overall aesthetics and sealing.

[0137] In some embodiments, as shown in Figures 1 and 2, the box body 4 is formed with at least two storage spaces, and a plurality of door body assemblies are provided, each door body assembly corresponding to one of the storage spaces, so as to drive the door panel 3 to move relative to the corresponding box door 2 during the opening or closing process of any box door 2.

[0138] In the present application, the cabinet 4 has at least two storage spaces, and the two storage spaces can be set to different storage environments (different temperatures, humidity, etc.) to meet the storage conditions of different items. Each storage space is provided with a corresponding door assembly, and the cabinet door 2 of the corresponding door assembly can open or close the corresponding storage space, so that the two storage spaces can be opened or closed independently, making it convenient for users to store or take out items in the storage space. The door panel 3 of each door assembly can also slide relative to the corresponding cabinet door 2. When the cabinet door 2 is closed, the door panel 3 can be flush with the cabinet body on the side, or when the cabinet door 2 is opened, the door panel 3 can avoid obstacles on both sides.

[0139] Specifically, the box body 4 has a first storage space and a second storage space. Correspondingly, the door assembly also includes a first door assembly and a second door assembly. The box door 2 of the first door 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 assembly is rotatably connected to the box body 4 to open or close the second storage space.

[0140] Furthermore, the first door assembly and the second door assembly are arranged vertically along the height of the door 2. The first door 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 active sliding door component 1, the first driven sliding door component 9, and the second driven sliding door component 18 can be used to control the movement of the corresponding door panel 3 and the door 2. The second door 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 active sliding door component 1, the first driven sliding door component 9, and the second driven sliding door component 18 can be used to control the movement of the corresponding door panel 3 and the door 2.

[0141] Finally, it should be noted that the above embodiments are intended only to illustrate the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, or equivalent substitutions of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application and are intended to be encompassed by the claims of the present application.
