[0080] The following is combined with Figures 1 to 14Describe 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 in the present application can also be applied to any other suitable equipment. The refrigeration equipment in the present application is, for example, applied as a refrigerator. However, it should be understood that the refrigeration equipment in the present application can also be applied as a freezer or any other suitable equipment.

[0081] In an embodiment of the present application, as Figures 1 to 3 shown, the sliding door device is applied to a refrigeration equipment, 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, and the box door 2 is adapted to open or close the storage space of the box body 4. The door panel 3 is slidably disposed outside the box door 2.

[0082] In this embodiment, the sliding door device includes: a transmission rod 19, a traction component 17, a main sliding door component 1 and a first driven sliding door component 9. The main sliding door component 1 is disposed on the box door 2, and the main sliding door component 1 is drivingly connected to the box body 4 through the traction component 17; the first driven sliding door component is coaxially disposed with the main sliding door component on the box door. The first driven sliding door component 9 is drivingly connected to the main sliding door component 1 through the transmission rod 19, and the first driven sliding door component 9 is connected to the door panel 3; during the opening or closing process of the box door 2, the box body 4 drives the main sliding door component 1 through the traction component 17, and the main sliding door component 1 drives the first driven sliding door component 9 through the transmission rod 19, so as 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.

[0083] In this embodiment, the box body 4 is the main part of the refrigeration equipment. A storage space is provided inside the box body 4 for storing food or other items that need to be refrigerated or frozen. The box door 2 is installed on the box body 4 through a certain rotational connection method (such as a hinge 5) and can rotate around one or more pivot points to realize the opening and closing of the storage space. The door panel 3, as an additional and slidable component, is disposed outside the box door 2.

[0084] In this embodiment, the traction component 17 (such as a chain, a belt or a steel wire rope) connects the box body 4 and the main sliding door component 1. When the box door 2 is opened or closed, power is transmitted to the main sliding door component 1 through the movement of the traction component 17. The main sliding door component 1 does not directly bear the weight of the door panel 3, but is the key to transmitting power. It converts the power from the traction component 17 into the driving force for the first driven sliding door component 9 through the transmission rod 19. The first driven sliding door component 9 closely cooperates with the main sliding door component 1, directly connects and drives the door panel 3 to move. Since the first driven sliding door component 9 bears the entire weight of the door panel 3, the design of the first driven sliding door component 9 needs to take into account both strength and flexibility to ensure the smooth sliding of the door panel 3.

[0085] For example, 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 through the transmission rod 19, 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, thereby reducing the problem of shaking of the door panel 3 when moving relative to the door 2.

[0086] According to the sliding door device of the embodiment, by setting the sliding door device including the transmission rod 19, 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 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 through the transmission rod 19, 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 through the transmission rod 19, 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.

[0087] In general, if Figures 1 to 3 As shown, a plurality of first driven sliding door components 9 are provided, and each first driven sliding door component 9 is transmission-connected to the active sliding door component 1 via a transmission rod 19 .

[0088] In this embodiment, two first driven sliding door components 9 are provided, and the two first driven sliding door components 9 are connected to the same active sliding door component 1 through a transmission rod 19, and the two first driven sliding door components 9 are coaxially arranged with the active sliding door component 1 to ensure the synchronization and consistency of the action. The "coaxial arrangement" here allows a certain error range (±5°) to take into account the deviation in the actual installation and manufacturing process.

[0089] In this embodiment, the active sliding door component 1 does not directly bear the weight of the door panel 3, but serves as the key to the transmission power, converting the power from the traction component 17 into the drive of the two first driven sliding door components 9 through the transmission rod 19. The two first driven sliding door components 9 are closely matched with the active sliding door component 1, directly connected and drive the door panel 3 to move. Since the two first driven sliding door components 9 bear the weight of the entire door panel 3, the smooth sliding of the door panel 3 is further ensured.

[0090] In some embodiments, Figure 4 As shown, the active sliding door component 1 includes: a traction component 17, 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. One end of the traction component 17 is connected to the box body 4, and the other end is connected to the first slider 11. The first slider 11 is slidably arranged on the first guide rail 131 and 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 transmission-connected to the first driven sliding door component 9 through the transmission rod 19; and the two ends of the flexible cable 14 are respectively connected to the first slider 11 and the second slider 12. When 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.

[0091] In this embodiment, the first base 13 is fixed on the box door 2, and the first guide rail 131 and the second guide rail 132 are formed on the lower side and the upper side 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 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, and is used to drive the first driven sliding door component 9. The flexible cable 14 can be a connecting component such as a traction rope, a transmission belt, etc., and 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 borne 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.

[0092] During the process of the box door 2 rotating outward and opening relative to the box body 4, the box body 4 drives the first slider 11 to slide towards 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. 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 preventing the door panel 3 from interfering with obstacles outside. During the process of the box 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. 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, preventing the door panel 3 from interfering with obstacles after closing.

[0093] 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 its two ends are respectively connected to one ends of the first slider 11 and the second slider 12. The second flexible cable bypasses the other end of the first base 13, and its two ends are respectively connected to the other ends of the first slider 11 and the second slider 12.

[0094] In this embodiment, by connecting the first flexible cable to the first slider 11 and the second slider 12 respectively after bypassing one end of the first base 13, 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 connecting the second flexible cable to the first slider 11 and the second slider 12 respectively after bypassing the other end of the first base 13, 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. Thus, 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 member 9 to enable the door panel 3 to slide relative to the box door 2 as the box door 2 opens and closes, so as to avoid interference with obstacles and affect the opening and closing of the box door 2.

[0095] In some embodiments, as Figure 4As shown, the active sliding door component 1 further includes a first fixed seat 15 and a second fixed seat 16. The first fixed seat 15 is connected to one end of the first 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 first flexible cable is slidably disposed in the first limiting groove; the second fixed 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 docked with the other ends of the first guide rail 131 and the second guide rail 132, and a part of the second flexible cable is slidably disposed in the second limiting groove.

[0096] Specifically, the first fixed seat 15 is connected to one end of the first base 13 and serves as an extension and support of 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 docked with one ends 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 fixed seat 16 corresponds to the first fixed seat 15. The second fixed seat 16 is connected to the other end of the first base 13 and provides 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, 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. 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, 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.

[0097] In order to achieve the installation of the active slider mechanism, in some embodiments, as Figure 4 shown, the first fixed seat 15 and / or the second fixed seat 16 are provided with fixing holes, and 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.

[0098] In this embodiment, by fixing the first fixed seat 15 and / or the second fixed 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 the need for complex disassembly work. This greatly improves the maintainability and flexibility of the equipment.

[0099] In 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 hole match the fixing to ensure the firmness and stability of the connection.

[0100] In some embodiments, Figure 5 , Figure 6 and Figure 7 As shown, the first driven sliding door component 9 includes: a second base 91, a third slider 92 and a fourth slider 93. A third guide rail 911 is formed on one side of the second base 91, and a fourth guide rail 912 is formed on the other side of the second base 91. The third slider 92 is slidably disposed on the third guide rail 911; the fourth slider 93 is connected to the third slider 92 and is slidably disposed on the fourth guide rail 912; the third slider 92 and / or the fourth slider 93 are transmission-connected to the second slider 12 via the transmission rod 19, and the third slider 92 and / or the fourth slider 93 are connected to the door panel 3.

[0101] In this embodiment, a third guide rail 911 is provided on the upper side of the second base 91, and a fourth guide rail 912 is provided on the lower side. The third slider 92 can move on the third guide rail 911, and the fourth slider 93 can move on the fourth guide rail 912. Since the third slider 92 is connected to the fourth slider 93, the two can move synchronously, and the transmission rod 19 is also connected thereto, so that the transmission rod 19 can drive the third slider 92 and the fourth slider 93 to move, thereby controlling the movement of the door panel 3 connected to the third slider 92 and the fourth slider 93.

[0102] The double sliders in this embodiment can prevent a single slider from bearing too much weight of the door panel 3, thereby improving stability during movement.

[0103] In some embodiments, the first driven sliding door component 9 further includes: a first support frame 94, a second support frame 95, a first ball 96, and a second ball 97. The first support frame 94 is disposed between the third slider 92 and the third guide rail 911, and a first limiting notch is formed; the second support frame 95 is disposed between the fourth slider 93 and the fourth guide rail 912, and a second limiting notch is formed; the first ball 96 is rollably disposed in the first limiting notch, and both sides of the first ball 96 abut against the third slider 92 and the third guide rail 911; the second ball 97 is rollably disposed in the second limiting notch, and both sides of the second ball 97 abut against the fourth slider 93 and the fourth guide rail 912.

[0104] In this embodiment, the first support frame 94 is arranged between the third guide rail 911 and the third slider 92. It is used to ensure that the first ball 96 can roll in the correct position, thereby supporting the sliding of the third slider 92. The first support frame 94 is designed with a first limiting notch, which is to accommodate the first ball 96 and limit its rolling range. The first limiting notch ensures that the first ball 96 will not be separated from the first support frame 94 during the rolling process, and also provides a certain rolling space for the first ball. The first ball is rollably arranged in the first limiting notch, one side of which abuts against the third guide rail 911, and the other side passes through the first limiting notch and abuts against the third slider 92. This design makes the third slider 92 no longer directly contact the third guide rail 911 and generate sliding friction when sliding, but realizes sliding through the rolling of the first ball 96. This method greatly reduces the friction resistance during the sliding process and improves the sliding efficiency. Since the rolling of the first ball 96 is 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 maintenance costs.

[0105] Similarly, the second support frame 95 is arranged between the fourth guide rail 912 and the fourth slider 93. It is used to ensure that the second ball 97 can roll in the correct position, thereby supporting the sliding of the fourth slider 93. A second limiting notch is designed on the second support frame 95, which is to accommodate the second ball 97 and limit its rolling range. The second limiting notch ensures that the second ball 97 will not separate from the second support frame 95 during the rolling process.

[0106] In summary, the combined design of the ball bearing and the support frame is adopted in this embodiment, which realizes effective support and assistance for the sliding of the third slider 92 in the third guide rail 911 and the fourth slider 93 in the fourth guide rail 912, and effectively improves the sliding efficiency.

[0107] In some embodiments, Figures 5 to 6 As shown, the first driven sliding door component 9 includes: a second base 91 and a third slider 92. A third guide rail 911 is formed on one side of the second base 91, and a fourth guide rail 912 is formed on the other side. The third slider 92 is slidably arranged on the third guide rail 911 and the fourth guide rail 912, and is transmission-connected to the second slider 12 through the transmission rod 19, and is connected to the door panel 3.

[0108] In this embodiment, a single slider is used, and a single third slider 92 is simultaneously provided on the third guide rail 911 and the fourth guide rail 912. The third slider 92 is connected to the transmission rod 19 and the door panel 3, so that when the transmission rod 19 drives the third slider 92 to move, the third slider 92 can drive the door panel 3 to move along the width direction of the box body 4. In this embodiment, the single slider is provided, and the structure of the entire component can be simplified compared to the solution of the double slider.

[0109] In some embodiments, Figure 8 As shown, the first driven sliding door component 9 further includes: a first support frame 94, a first ball 96 and a second ball 97. A portion of the first support frame 94 is disposed between the third slider 92 and the third guide rail 911, and another portion is disposed between the third slider 92 and the fourth guide rail 912, forming a first limiting notch and a second limiting notch; the first ball 96 is rollably disposed in the first limiting notch, and both sides of the first ball 96 abut against the third slider 92 and the third guide rail 911; the second ball 97 is rollably disposed in the second limiting notch, and both sides of the second ball 97 abut against the third slider 92 and the fourth guide rail 912.

[0110] In this embodiment, a single first support frame 94 is used to support the balls at two locations. It is used to ensure that the first ball 96 and the second ball 97 can roll in the correct position. The first support frame 94 is designed with a first limiting notch and a second limiting notch, the first limiting notch accommodates the first ball 96, and the second limiting notch accommodates the second ball 97. The first limiting notch ensures that the first ball 96 will not be separated from the first support frame 94 during the rolling process, and the second limiting notch ensures that the second ball 97 will not be separated from the first support frame 94 during the rolling process. This design makes the third slider 92 no longer directly contact the third guide rail 911 and the fourth guide rail 912 and generate sliding friction when sliding, but achieves sliding through the rolling of the first ball 96 and the second ball 97. This method greatly reduces the friction resistance during the sliding process and improves the sliding efficiency. Since the rolling of the first ball 96 and the second ball 97 is low friction, it can significantly reduce the wear between the slider and the guide rail. This helps to extend the service life of the components and reduce maintenance costs.

[0111] In some embodiments, Figures 5 to 6 As shown, the first driven sliding door component 9 includes: a second base 91 and a third slider 92. The second base 91 is formed with a third guide rail 911; the third slider 92 is slidably arranged on the third guide rail 911, and is transmission-connected to the second slider 12 through the transmission rod 19, and is connected to the door panel 3.

[0112] In this embodiment, a single slider and a single guide rail are used, and a single third slider 92 is set on the third guide rail 911. The third slider 92 is connected to the transmission rod 19 and the door panel 3, so that when the transmission rod 19 drives the third slider 92 to move, the third slider 92 can drive the door panel 3 to move along the width direction of the box body 4. Compared with the previous solution, this embodiment simplifies the structure of the entire component by setting a single slider.

[0113] In some embodiments, Figure 9As shown, the first driven sliding door component 9 further includes: a first support frame 94 and a first ball 96. The first support frame 94 is disposed between the third slider 92 and the third guide rail 911, and a first limiting notch is formed; the first ball 96 is rotatably disposed in the first limiting notch, and two sides of the first ball 96 abut against the third slider 92 and the third guide rail 911.

[0114] In this embodiment, a single first support frame 94 is used to roll the ball. It is used to ensure that the first ball 96 can roll in the correct position. A first limiting notch is designed on the first support frame 94, and the first limiting notch accommodates the first ball 96. The first limiting notch ensures that the first ball 96 will not separate from the first support frame 94 during the rolling process. This design makes the third slider 92 no longer directly contact the third guide rail 911 and generate sliding friction when sliding, but achieves sliding through the rolling of the first ball 96. This method greatly reduces the friction resistance during the sliding process and improves the sliding efficiency.

[0115] In one example, if Figures 5 to 6 As shown, in order to facilitate the installation of the door panel 3, the first driven sliding door component 9 further includes a first hanging bracket 98. The first hanging bracket 98 is connected to the outer side of the third sliding block 92 or the fourth sliding block 93, and is used to hang the door panel 3.

[0116] In this embodiment, the first hanger 98 is used as the hanging point of the door panel 3, so that the installation of the door panel 3 becomes simpler and faster, because the installer only needs to hang the door panel 3 on the first hanger 98, without complicated fixing or connecting operations. The first hanger 98 is provided with a connection structure that matches the outer side of the third slider 92 or the fourth slider 93 to ensure that it can be firmly connected to the third slider 92 or the fourth slider 93. This connection structure can be bolted, welded or plugged in or other reliable connection methods. At the same time, the first hanger 98 is provided with a hanging point suitable for hanging the door panel 3 to bear the weight of the door panel 3 and the force generated during the sliding process.

[0117] During the installation process, the installer will first firmly connect the first bracket 98 to the outside of the third slider 92 or the fourth slider 93. Then, they will hang or connect the corresponding part of the door panel 3 to the first bracket 98. Since the connection between the first bracket 98 and the third slider 92 or the fourth slider 93 is firm, the door panel 3 will also maintain a stable connection state with the third slider 92 or the fourth slider 93 through the first bracket 98.

[0118] In one embodiment of the present application, a door assembly is provided, such 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.

[0119] 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 through the transmission rod 19, 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.

[0120] According to the door assembly provided in the embodiment, a sliding door device including a transmission rod 19, 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 through the transmission rod 19, 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 through the transmission rod 19, 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.

[0121] 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.

[0122] 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 door 2. The second driven sliding door component 18 is arranged at the bottom end of the door 2. During the opening or closing process of 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 through the transmission rod 19, 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 the obstacles outside. 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 door 2, which can effectively improve the stability during movement.

[0123] 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 caused by the direction deviation. This restrictive effect ensures the stability of the door panel 3.

[0124] To facilitate the installation of the sliding door device, a first end cover 21 is provided at the top end of the door 2. An installation groove for arranging 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 door 2. An installation groove for arranging 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.

[0125] In one embodiment, as Figure 10 、 Figure 11 and Figure 12 shown, the second driven sliding door component 18 includes: a third base 181, a fifth slider 182. A fifth guide rail 1811 is formed inside the third base 181, and the third base 181 is hung on the door panel 3. The fifth slider 182 is slidably arranged (generally inscribed) in the fifth guide rail 1811, and the fifth slider 182 is connected to the door 2; a second hanging bracket 183 is connected to the outside of the third base 181 for hanging the door panel 3.

[0126] In this embodiment, a fifth guide rail 1811 is provided inside the third base 181. The fifth slider 182 is connected to the cabinet door 2, and the outside of the third base 181 is connected to the door panel 3. When the door panel 3 moves relative to the cabinet door 2, the third base 181 moves relative to the fifth slider 182 through the fifth guide rail 1811, so as to cooperate with guiding the movement of the door panel 3 and the cabinet door 2.

[0127] In one embodiment, as Figures 10 to 12 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.

[0128] In this embodiment, the second hanging bracket 183 is the same as the first hanging bracket 98 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 hanging bracket 98 and the second hanging bracket 183 without performing complex fixing or connecting operations.

[0129] During the installation process, the installer will first firmly connect the first hanging bracket 98 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 98 and the second hanging bracket 183. Since the connection between the first hanging bracket 98 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 98 and the second hanging bracket 183.

[0130] It should be noted that in practical applications, the designs of the first slider 11, the second slider 12, the third slider 92, the fourth slider 93, and the fifth 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.

[0131] From the perspective of materials, the first slider 11, the second slider 12, the third slider 92, the fourth slider 93, and the fifth 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.

[0132] In terms of structural design, the first slider 11, the second slider 12, the third slider 92, the fourth slider 93, and the fifth slider 182 can adopt various forms of guide rail contact surfaces, such as plane 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 plane 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.

[0133] In an embodiment of another aspect of the present application, as Figures 1 to 14 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.

[0134] By providing a door panel 3 on the box door 2, when the refrigeration device is an embedded type and is disposed in a groove-shaped space, or is disposed between two cabinets, the door panel 3 can be set flush with the side wall of the groove or the cabinets on both sides, so as to reduce the gap between the refrigeration device and the adjacent wall or cabinet, making it more beautiful.

[0135] 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 of the box door 4 of the box body, 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 normally opened or closed.

[0136] 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 usability. 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.

[0137] 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, and its specific implementation manners can refer to the above embodiments and will not be elaborated in this application.

[0138] In some embodiments, as Figure 13 and Figure 14As 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 to move a preset distance on the box door 2 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.

[0139] 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 to move a preset distance on the box door 2 in a direction away from or towards the hinge 5. 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 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.

[0140] For example, as Figure 13 and Figure 14 shown, during the opening process of the box door 2, the active sliding door component 1 drives the door panel 3 to move a preset distance along the box door 2 in a direction away from the hinge 5. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet body 7, enabling the box door 2 to be fully opened, facilitating users to access items.

[0141] Similarly, during the closing process of the box door 2, the active sliding door component 1 drives the door panel 3 to move a preset distance along the box door 2 in a direction 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 box door 2 to be fully closed, maintaining the overall aesthetics and sealing performance.

[0142] 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.

[0143] In this 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, and the door panel 3 can be flush with the side cabinet when the box door 2 is closed, or the door panel 3 can avoid the obstacles on both sides when the box door 2 is opened.

[0144] 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.

[0145] Further, the first door body assembly and the second door body assembly are arranged one above the other 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.

[0146] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended 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.
