In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0042] Combine the following Figures 1 to 9 The sliding door device, door assembly and refrigeration equipment of the present application are described. The sliding door device and door assembly of the present application can be applied to the door 2 or cabinet door of household appliances, such as the door 2 of a refrigerator, but it should be understood that the door assembly of the present application can also be applied to any other suitable equipment. The refrigeration equipment of the present application is applied to a refrigerator, for example, but it should be understood that the refrigeration equipment of the present application can also be applied to a freezer or any other suitable equipment.

[0043] In one embodiment of the present application, Figures 1 to 3 As shown, 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, 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.

[0044] 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 arranged 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; the first driven sliding door component 9 is arranged on the box door 2, and the first driven sliding door component 9 is transmission-connected to the active sliding door component 1, and the first driven sliding door component 9 and / or the active sliding door component 1 are connected to the door panel 3; in the process of opening or closing the box door 2, 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, so that the first driven sliding door component 9 cooperates with the active sliding door component 1 to drive the door panel 3 to move relative to the width direction of the box door 2.

[0045] In this embodiment, the box body 4 is the main part of the refrigeration device, and 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 rotating connection method (such as a hinge 5), and can rotate around one or more axis points to realize the opening and closing of the storage space. The door panel 3 is an additional, slidable component and is arranged on the outer side of the box door 2.

[0046] In this embodiment, the traction component 17 (such as a chain, belt or wire rope) connects the box body 4 and the active sliding door component 1. When the box door 2 is opened or closed, the power is transmitted to the active sliding door component 1 through the movement of the traction component 17. 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 driving the first driven sliding door component 9. The first driven sliding door component 9 is closely matched with the active sliding door component 1, directly connected and drives the door panel 3 to move.

[0047] In the case where the door panel 3 is connected only through 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 take into account both strength and flexibility to ensure the smooth sliding of the door panel 3. During the opening or closing 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 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 on the 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 opening or closing of 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 it moves relative to the door 2.

[0048] 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.

[0049] 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.

[0050] 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 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, 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 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.

[0051] In some embodiments, Figure 4 As 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 a 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; 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.

[0052] 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 inner side and the outer 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.

[0053] When the door 2 is rotated to the outside of the box body 4 to open, the box body 4 drives the first slider 11 to slide in the direction close to the hinge 5 through the traction component 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 drives the first driven sliding door component 9, and the first driven sliding door component 9 drives the door panel 3 to move, thereby avoiding interference between the door panel 3 and obstacles on the outside. When the door 2 is rotated to the side of the box body 4 to close, the box body 4 drives the first slider 11 to slide in the direction away from the hinge 5 through the traction component 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 drives the first driven sliding door component 9, and the first driven sliding door component 9 drives the door panel 3 to move, thereby avoiding interference between the door panel 3 and obstacles after closing.

[0054] In some embodiments, Figure 4 As shown, the flexible cable 14 includes: a first flexible cable and a second flexible cable. The first flexible cable passes around one end of the first base 13, and both ends are respectively connected to one end of the first slider 11 and the second slider 12. The second flexible cable passes around the other end of the first base 13, and both ends are respectively connected to the other ends of the first slider 11 and the second slider 12.

[0055] In this embodiment, by passing one end of the first flexible cable around the first base 13 and connecting them to the first slider 11 and the second slider 12 respectively, when the first slider 11 slides in the direction away from the first base 13 under the drive of the box body 4, the first slider 11 drives the second slider 12 to slide in the direction close to the first base 13 through the first flexible cable; at the same time, by passing the other end of the second flexible cable around the first base 13 and connecting them to the first slider 11 and the second slider 12 respectively, when the first slider 11 slides in the direction 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 in the direction close to the other end of the first base 13 through the second flexible cable, so that when the first slider 11 slides to the two ends of the first base 13 respectively, the second slider 12 and the first slider 11 can be driven to slide in the opposite direction, and then cooperate with the first driven sliding door component 9 to enable the door panel 3 to slide relative to the box door 2 as the box door 2 rotates when the box door 2 is opened and closed, so as to avoid interference with obstacles and affecting the opening and closing of the box door 2.

[0056] In some embodiments, Figure 4 As 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, and both ends of the first limiting groove are butted with one end 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 fixing seat 16 is connected to the other end of the first base 13, and is formed with a second limiting groove, and both ends of the second limiting groove are butted with 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 disposed in the second limiting groove.

[0057] Specifically, the first fixed seat 15 is connected to one end of the first base 13, 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, which 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 butted with one end of the first guide rail 131 and the second guide rail 132. The existence of the first limiting groove limits the deviation and shaking of the first flexible cable during the sliding process, thereby improving the operation accuracy and reliability of the entire active sliding door component 1. The second fixed seat 16 corresponds to the first fixed seat 15, and the second fixed seat 16 is connected to the other end of the first base 13 to provide 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, which is similar in design to 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 connected to the other ends of the first guide rail 131 and the second guide rail 132 to provide guidance and limit 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.

[0058] In order to realize the installation of the active slider mechanism, in some embodiments, as Figure 4 As shown, the first fixing seat 15 and / or the second fixing seat 16 are provided with fixing holes, and the active sliding door component 1 also includes fixing pieces, which pass through the fixing holes to be connected with the door 2, so that the entire active sliding door component 1 can be fixed on the door 2.

[0059] 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 complicated disassembly work. This greatly improves the maintainability and flexibility of the equipment.

[0060] 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.

[0061] In some embodiments, Figure 4 , Figure 5 and Figure 6As shown, the first driven sliding door component 9 is 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, and the outer side is connected to the door panel 3. A third guide rail 911 is formed in the second base 91; the third slider 92 is slidably disposed 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.

[0062] 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, so that when the second base 91 moves, the door panel 3 can be driven 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 box door 2 (or may be a part of the box door). This means that when the third slider 92 moves in the third guide rail 911, the door panel 3 and the box door 2 move relative to each other through the relative movement of the second base 91 and the third slider 92.

[0063] When the second slider 12 moves along the second guide rail 132, the second base 91 will also move because the inner side of the second base 91 is connected to the second slider 12. In this process, since 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 will drive the door panel 3 to move accordingly through the relative movement between the third guide rail 911 and the third slider 92.

[0064] In some embodiments, Figures 4 to 6 As shown, the first driven sliding door component 9 also includes: a first ball support. The first ball support 93 is slidably inscribed in the third guide rail 911, and the third slider 92 is slidably inscribed in 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, chain, etc.) or a direct action. As the second base 91 moves, the third slider 92 moves relative to it. At this time, the third slider 92, with the assistance of the first ball support 93, slides in the third guide rail 911 with low friction and high efficiency. Due to the existence of the first ball support 93, the sliding process of the third slider 92 becomes more stable and reliable, thereby ensuring the stable operation of the entire first driven sliding door component 9.

[0065] Specifically, the first ball support member 93 includes: a support frame and a ball (not shown). The support frame is arranged between the third guide rail 911 and the third slider 92, and a limit notch is formed on the support frame; the ball is rollably arranged in the limit notch, one side of the ball abuts against the third guide rail 911, and the other side of the ball passes through the limit notch and abuts against the third slider 92.

[0066] In this embodiment, the support frame is arranged between the third guide rail 911 and the third slider 92. It is used to ensure that the ball can roll in the correct position, thereby supporting the sliding of the third slider 92. A limited notch is designed on the support frame to accommodate the ball and limit its rolling range. The limited notch ensures that the ball will not leave the support frame during the rolling process, and also provides a certain rolling space for the ball. The ball is rollably arranged in the limited notch, one side of which abuts against the third guide rail 911, and the other side passes through the limited notch to abut 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 achieves sliding through the rolling of the ball. This method greatly reduces the friction resistance during the sliding process and improves the sliding efficiency. Since the rolling of the ball 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.

[0067] 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 a driving force from the second slider 12). In this process, the second base 91 pushes the ball to roll in the limiting notch of the support frame. One side of the ball keeps in contact with the third guide rail 911 and rolls, while the other side keeps in contact with the third slider 92 and rolls. In this way, the first ball support member 93 provides stable and efficient support for the sliding of the third slider 92.

[0068] In summary, the first ball support member 93 in this embodiment realizes 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.

[0069] In addition, if Figure 5 and Figure 6As shown, 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 in the third guide rail 911, the movement range of the third slider 92 is limited by the contact between the limit members 912 and the third slider 92. The limit members 912 should be accurately installed at appropriate positions of 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 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.

[0070] During operation, when the third slider 92 moves in the third guide rail 911, the second base 91 will slide according to the external driving force (such as the driving force from the second slider 12). In this process, if the relative position of the third slider 92 and the second base 91 attempts to exceed the predetermined moving 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 limiting them within the predetermined range.

[0071] In one example, if Figures 1 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 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.

[0072] In this embodiment, the first hanger 94 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 94, without complicated fixing or connecting operations. The first hanger 94 is provided with a connection structure matching the outer side of the second base 91 to ensure that it can be firmly connected to the second base 91. This connection structure can be bolted, welded or other reliable connection methods. At the same time, the first hanger 94 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.

[0073] During the installation process, the installer will first firmly connect the first hanger 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 hanger 94. Since the connection between the first hanger 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 hanger 94.

[0074] In some embodiments, Figures 1 to 5As shown, the first driven sliding door component 9 is provided with a fixing plate 95 for connecting the door panel 3, 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 carry 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.

[0075] Since 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, 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.

[0076] 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.

[0077] Due to the dispersion of gravity, the shaking of the door panel 3 during the movement will be reduced accordingly, thereby improving the stability and reliability of the sliding door device. In addition, since 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, thereby increasing the sensitivity of the entire sliding door device.

[0078] In other embodiments, Figures 1 to 5 As shown, the first driven sliding door component 9 is provided with a fixing plate 95 for connecting the door panel 3, and the active sliding door component 1 is separated from the fixing plate 95, that is, at this time, the door panel 3 is only connected through the first driven sliding door component 9, 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.

[0079] 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 opening or closing process of 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.

[0080] In this embodiment, since the active sliding door component 1 does not bear the weight of the door panel 3, it can focus more on providing a smooth driving force and avoid being disturbed by the weight of the door panel 3 or external forces in other directions. In addition, the first driven sliding door component 9 bears the weight of the door panel 3 alone, and it can be more conveniently adjusted 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.

[0081] 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.

[0082] 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 to drive the door panel 3 to move in the width direction relative to 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 may not bear the weight of the door panel 3 according to the specific setting, 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.

[0083] 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 in the door opening process.

[0084] 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.

[0085] 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. In the process of opening or closing 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 obstacles on the outside. In 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.

[0086] 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 limit the movement direction of the door panel 3. The door panel 3 moves along a predetermined trajectory during the sliding process, avoiding shaking and instability caused by directional deviation. This limiting effect ensures the stability of the door panel 3.

[0087] In order to facilitate the installation of the sliding door device, the top end of the box door 2 is provided with a first end cover 21, and the first end cover 21 is provided with a mounting groove for accommodating the traction component 17, the active sliding door component 1, and the first driven sliding door component 9. 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 mounting groove can be adjusted to meet different installation requirements. Similarly, the bottom end of the box door 2 is provided with a second end cover 22, and the second end cover 22 is provided with a mounting groove for accommodating the second driven sliding door component 18. 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 mounting groove can be adjusted to meet different installation requirements.

[0088] In one embodiment, if Figure 7 As 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 in the third base 181, and the third base 181 is connected to the door panel 3. The fourth slider 182 is slidably disposed in (generally inscribed in) the fourth guide rail 1811, and the fourth slider 182 is connected to the box door 2; the second hanging bracket 183 is connected to the outer side of the third base 181, and is used to hang the door panel 3.

[0089] 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 as to cooperate and guide the movement of the door panel 3 and the box door 2.

[0090] In one embodiment, if Figure 7 As shown, 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.

[0091] 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 quicker, 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.

[0092] During the installation process, the installers will first firmly connect the first hanger 94 and the second hanger 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 hanger 94 and the second hanger 183. Since the connection between the first hanger 94 and the second base 91 and the connection between the second hanger 183 and the third base 181 are firm, the door panel 3 will also maintain a stable connection state through the first hanger 94 and the second hanger 183.

[0093] 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 in the fourth guide rail 1811, and the fourth slider 182 is slidably inscribed in the second ball bearing support 184. With the assistance of the second ball bearing support 184, the fourth slider 182 slides in the fourth guide rail 1811 with low friction and high efficiency. Due to the existence of the second ball bearing support 184, the sliding process of the fourth slider 182 becomes more stable and reliable, thereby 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 bearing support 184 is the same as that of the first ball bearing support 93, which will not be repeated here.

[0094] 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 adaptable 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.

[0095] From the material point of view, 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 is intended to improve the durability of the sliders, reduce wear and noise during sliding, and ensure smooth sliding.

[0096] 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 plane contact, ball contact or sliding bearing contact. These different contact methods have their own advantages and disadvantages. For example, ball contact can reduce friction and wear, but the cost is high; while plane contact has a simple structure, but may require more frequent lubrication and maintenance. Therefore, when choosing, factors such as usage conditions, cost-effectiveness and maintenance convenience should be comprehensively considered.

[0097] In another embodiment of the present application, Figures 1 to 9As shown, a refrigeration device is provided, comprising: a box body 4 and a door assembly as provided in any of the above embodiments. The box body 4 forms a storage space, and the door 2 is rotatably connected to the box body 4, suitable for opening or closing the storage space. The structure of the door assembly can refer to the above embodiments, and will not be repeated here.

[0098] 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 walls or cabinets, which is more beautiful.

[0099] 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.

[0100] The combination of the door 2 and the door panel 3 can prevent the door panel 3 from interfering with surrounding objects when the refrigeration device is opened and closed, greatly improving the convenience of use. This design advantage is particularly obvious in a narrow kitchen environment. In addition, the arrangement of the slider and the guide rail in the active sliding door component 1 enables the door panel 3 to move smoothly during the opening and closing process, thereby improving the service life and stability of the refrigerator.

[0101] It can be understood that if the door body assembly has the beneficial effects of the above embodiments, then the refrigeration equipment will correspondingly have the beneficial effects of the above embodiments. The specific implementation methods thereof may refer to the above embodiments, and will not be described in detail in this application.

[0102] In some embodiments, Figure 8 and Fig. 9 As shown, the door assembly and the box 4 are used to be arranged in the installation space 8 formed between the first cabinet 6 and the second cabinet 7. The outer side of the installation space 8 is provided with an opening. This design allows the door assembly and the box 4 to be integrally embedded in the cabinet. In 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 close to the hinge 5, so that the door panel 3 avoids the side walls of the first cabinet 6 and the second cabinet 7.

[0103] In the process of the 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 door 2 in a direction away from or close to the hinge 5. In order to avoid interference between the door panel 3 and 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 movement of the preset distance without colliding or getting stuck with the side walls of the cabinets.

[0104] For example, Figure 8 and Fig. 9 As shown, during the opening process of the door 2, 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, so that the door 2 can be fully opened, which is convenient for users to store and retrieve items.

[0105] Similarly, when the door 2 is closed, 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, so that the door 2 can be completely closed, maintaining the overall aesthetics and sealing.

[0106] In some embodiments, Figure 1 and Figure 2 As shown, 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 corresponds 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 process of opening or closing any box door 2.

[0107] 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, which is 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, and 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.

[0108] 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.

[0109] Further, 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 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 corresponding door panel 3 and the box door 2 to move accordingly. 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 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 corresponding door panel 3 and the box door 2 to move accordingly.

[0110] 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 is described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications or equivalent substitutions 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 be included in the scope of the claims of the present invention.
