[0063] The following is combined with Figures 1 to 10The door assembly and refrigeration device of the present application are described. The door assembly in the present application can be applied to a door 2 or a cabinet door of a household appliance, such as a door 2 of a refrigerator, but it should be understood that the door assembly in the present application can also be applied to any other suitable device. The refrigeration device in the present application is applied to a refrigerator, for example, but it should be understood that the refrigeration device in the present application can also be applied to a freezer or any other suitable device.

[0064] In one embodiment of the present application, Figure 1 and Figure 2 As shown, the door assembly is applied to a refrigeration device, which includes a box body 4. The door assembly includes: an active sliding door mechanism 1, a first driven sliding door mechanism 9, a box door 2 and a door panel 3. The box door 2 is rotatably connected to the box body 4. The box door 2 is suitable for opening or closing the storage space of the box body 4. The door panel 3 is slidably arranged on the outside of the box door 2.

[0065] In this embodiment, a first mounting groove 21 and a second mounting groove 22 are respectively provided on the left and right sides of the top of the box door 2, and the active sliding door mechanism 1 is selectively provided in the first mounting groove 21 or the second mounting groove 22 to use a left-side hinged box door 2 or a right-side hinged box door 2, and the active sliding door mechanism 1 is transmission connected to the box body 4; the first driven sliding door mechanism 9 is provided on the box door 2, and is transmission connected to the active sliding door mechanism 1, and the first driven sliding door mechanism 9 is 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 mechanism 1, and the active sliding door mechanism 1 drives the first driven sliding door mechanism 9, 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 mechanism 9.

[0066] 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 hinged to the box body 4 on the left side or on the right side as required. It can rotate around one or more axis points to open and close the storage space. The door panel 3 is an additional, slidable component and is arranged on the outside of the box door 2.

[0067] In this embodiment, when the box door 2 is opened or closed, the box body 4 transmits power to the first driven sliding door mechanism 9 through the movement of the active sliding door mechanism 1. The active sliding door mechanism 1 does not directly bear the weight of the door panel 3, but serves as the key to the transmission power, converting the power of the box body 4 into the drive of the first driven sliding door mechanism 9. The first driven sliding door mechanism 9 closely cooperates with the active sliding door mechanism 1, directly connects and drives the door panel 3 to move.

[0068] Specifically, during the process of opening or closing the door 2, the box body 4 drives the active sliding door mechanism 1. The active sliding door mechanism 1 drives the first driven sliding door mechanism 9 to drive the door panel 3 to move in the width direction relative to the door 2 through the first driven sliding door mechanism 9, thereby avoiding interference between the door panel 3 and obstacles outside. In this process, the active sliding door mechanism 1 that directly bears the driving force does not bear the weight of the door panel 3, while the first driven sliding door mechanism 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 mechanism 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.

[0069] According to the door body assembly of the embodiment, an active sliding door mechanism, a first driven sliding door mechanism, a box door and a door panel are provided. The door body assembly can be applied to a box door that rotates on the left or right side. The active sliding door mechanism can be selectively set in the first mounting groove or the second mounting groove according to actual needs, and the active sliding door mechanism is transmission-connected with the first driven sliding door mechanism, and the first driven sliding door mechanism is connected with the door panel, so that the box body drives the first driven sliding door mechanism through the active sliding door mechanism, and the door panel is driven to move relative to the width direction of the box door through the first driven sliding door mechanism, so that the door panel avoids obstacles on both sides and solves the interference problem in the door opening process. At the same time, the active sliding door mechanism of the door body assembly that directly bears the driving force does not bear the weight of the door panel, and the first driven sliding door mechanism connected to the door panel bears the weight of the entire door panel, so that in the process of opening or closing the box door, the active sliding door mechanism can be prevented from being subjected to external forces in other directions, and the problem of the door panel shaking when moving relative to the box door is reduced.

[0070] In some embodiments, Figures 1 to 4 As shown, the door body assembly also includes: a first hinge 51 and a second hinge 52; the first hinge 51 is detachably connected to the left side of the box body 4 and the box door 2, and the second hinge 52 is detachably connected to the right side of the box body 4 and the box door 2; when the active sliding door mechanism 1 is set in the first mounting groove 21, the box door 2 is rotatably connected to the left side of the box body 4 through the first hinge 51; when the active sliding door mechanism 1 is set in the second mounting groove 22, the box door 2 is rotatably connected to the right side of the box body 4 through the second hinge 52.

[0071] In this embodiment, the first hinge 51 and the second hinge 52 are both detachably connected between the box body 4 and the box door 2, and the corresponding active sliding door mechanism 1 is selectively arranged in the first installation groove 21 on the left side or the second installation groove 22 on the right side. When the active sliding door mechanism 1 is arranged in the first installation groove 21, the box door 2 is rotatably connected on the left side of the box body 4 through the first hinge 51. Figure 2 Similarly, when the active sliding door mechanism 1 is arranged in the second installation groove 22, the door 2 is rotatably connected to the right side of the box body 4 through the second hinge 52, as shown in FIG.Figure 1 As shown, the cabinet door 2 is a left-opening door at this time. This design allows the cabinet door 2 to be opened in different ways to meet different usage scenarios and requirements.

[0072] In this way, the user can easily install or disassemble the hinge as needed, thereby changing the opening mode of the cabinet door 2.

[0073] In some embodiments, as Figure 5 shown, the active sliding door mechanism 1 includes: a traction member 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 member 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 disposed on the first guide rail 131 and is connected to the box body 4 through the traction member 17; the second slider 12 is slidably disposed on the second guide rail 132 and is in transmission connection with the first driven sliding door mechanism 9; both ends of the flexible cable 14 are respectively connected to the first slider 11 and the second slider 12. In the case where the box body 4 drives the first slider 11 to move on the first guide rail 131 through the traction member 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.

[0074] In this embodiment, the first base 13 is fixed on the cabinet door 2, and the first guide rail 131 and the second guide rail 132 are respectively formed on its inner and outer sides. The first guide rail 131 and the second guide rail 132 respectively provide tracks for the sliding of the first slider 11 and the second slider 12. The first slider 11 is slidably sleeved on the first guide rail 131 and is connected to the box body 4 through the traction member 17, and is driven by the box body 4 to move on the first guide rail 131. The second slider 12 is also slidably sleeved on the second guide rail 132, but is connected to the first driven sliding door mechanism 9 for driving the first driven sliding door mechanism 9. The flexible cable 14 can be a connecting component such as a traction rope or a transmission belt. Both ends of the flexible cable 14 are respectively connected to the first slider 11 and the second slider 12, so that the first slider 11 can drive the second slider 12 to move synchronously and move in opposite directions. This design ensures that during the process of the door panel 3 sliding along the width direction of the box body 4, only the driving force of the traction member 17 is borne by the first slider 11 and the second slider 12, and the weight of the door panel 3 in the vertical direction does not need to be borne, and only the first driven sliding door mechanism 9 bears the weight of the entire door panel 3, reducing the problem of shaking when the door panel 3 moves relative to the cabinet door 2.

[0075] 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 mechanism 9, and the first driven sliding door mechanism 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 towards the box body 4 and closing, 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 mechanism 9, and the first driven sliding door mechanism 9 drives the door panel 3 to move, preventing the door panel 3 from interfering with obstacles after closing.

[0076] In some embodiments, as Figure 5 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.

[0077] 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 driven by 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 driven by 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 mechanism 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.

[0078] In some embodiments, as Figure 5As shown, the active sliding door mechanism 1 further includes a first fixing base 15 and a second fixing base 16. The first fixing base 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 fixing base 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.

[0079] Specifically, the first fixing base 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 fixing base 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 accuracy and reliability of the entire active sliding door mechanism 1. The second fixing base 16 corresponds to the first fixing base 15. The second fixing base 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 fixing base 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 mechanism 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.

[0080] In order to achieve the installation of the active slider mechanism, in some embodiments, as Figure 5 shown, fixing holes are provided on the first fixing base 15 and / or the second fixing base 16. The active sliding door mechanism 1 further includes fixing members, and the fixing members pass through the fixing holes to be connected to the box door 2, so that the entire active sliding door mechanism 1 can be fixed on the box door 2.

[0081] In this embodiment, by fixing the first fixing base 15 and / or the second fixing base 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 mechanism 1 and the box door 2. When it is necessary to repair or replace the active sliding door mechanism 1, the active sliding door mechanism 1 can be removed from the box door 2 by simply removing the fixing members without complicated disassembly work. This greatly improves the maintainability and flexibility of the equipment.

[0082] In specific implementation, appropriate fasteners such as screws, bolts, rivets, etc. can be selected according to the structure and material of the box door 2. At the same time, it is also necessary to ensure that the position and size of the fixing holes match the fasteners to ensure the firmness and stability of the connection.

[0083] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 shown, the first driven sliding door mechanism 9 includes: a second base 91 and a third slider 92. The inner side of the second base 91 is connected to the second slider 12 through a fixing plate 95, the outer side is connected to the door panel 3, and a third guide rail 911 is formed inside the second base 91; the third slider 92 is slidably arranged in the third guide rail 911, and the third slider 92 is connected to the box door 2. When the second slider 12 moves on the second guide rail 132, the second slider 12 drives the second base 91 to move relative to the third slider 92 through the third guide rail 911.

[0084] In this embodiment, the inner side of the second base 91 is connected to the second slider 12, and the second base 91 moves along with the movement of the second slider 12 on the second guide rail 132. At the same time, its outer side is directly connected to the door panel 3. In this way, when the second base 91 moves, it can drive the door panel 3 to move together. The second base 91 is internally designed with a third guide rail 911 for accommodating and guiding the sliding of the third slider 92. The third slider 92 not only interacts with the third guide rail 911 to achieve the sliding function, but it is also connected to the box door 2 (or possibly a part of the box door). This means that when the third slider 92 moves in the third guide rail 911, through the relative movement of the second base 91 and the third slider 92, the door panel 3 and the box door 2 can move relative to each other.

[0085] When the second slider 12 moves along the second guide rail 132, since the inner side of the second base 91 is connected to the second slider 12, the second base 91 will also move accordingly. During this process, since the third slider 92 is fixed to the box door 2 and is slidably arranged in the third guide rail 911 of the second base 91, when the second base 91 moves, it will drive the door panel 3 to move correspondingly through the relative movement between the third guide rail 911 and the third slider 92.

[0086] In some embodiments, such as Figures 5 to 7As shown, the first driven sliding door mechanism 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 smoother and more reliable, thereby ensuring the stable operation of the entire first driven sliding door mechanism 9.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] In summary, through the combined design of the support frame and the ball, the first ball support member 93 in this embodiment effectively supports and assists the sliding of the third slider 92 in the third guide rail 911, thus effectively improving the sliding efficiency.

[0091] In addition, as Figure 6 and Figure 7 shown, a limiting member 912 is provided on the third guide rail 911, and the limiting member 912 is located on both sides of the third slider 92; when the third slider 92 moves within the third guide rail 911, the movement range of the third slider 92 is restricted by the contact between the limiting member 912 and the third slider 92. The limiting member 912 should be precisely installed at the appropriate position on the third guide rail 911 to ensure that they can effectively limit the movement range of the third slider 92. Generally, the position of the limiting member 912 is determined according to the movement requirements of the door panel 3 and the box door 2. The shape and size of the limiting member 912 should be determined according to the contour and movement of the third slider 92 to withstand the impact force generated during contact and maintain a stable limiting effect.

[0092] During operation, when the third slider 92 moves within the third guide rail 911, the second base 91 will slide under the action of an external driving force (such as the driving force from the second slider 12). During this process, if the relative position between the third slider 92 and the second base 91 attempts to exceed the predetermined movement range, the third slider 92 will come into contact with the limiting member 912 on either side. Once contact occurs, the limiting member 912 will prevent the third slider 92 and the second base 91 from continuing to move, thereby restricting them within the predetermined range.

[0093] In one example, as Figures 1 to 6 shown, for the convenience of installing the door panel 3, the first driven sliding door mechanism 9 further includes: a first hanging bracket 94. The first hanging bracket 94 is connected to the outside of the second base 91 and is used for hanging the door panel 3.

[0094] In this embodiment, the first hanging bracket 94 serves as the hanging point for the door panel 3, making the installation of the door panel 3 simpler and faster because the installer only needs to hang the door panel 3 on the first hanging bracket 94 without performing complex fixing or connecting operations. The first hanging bracket 94 is provided with a connection structure that matches the outside of the second base 91 to ensure that it can be firmly connected to the second base 91. This connection structure can be a bolt connection, welding, or other reliable connection methods. At the same time, the first hanging bracket 94 is provided with hanging points suitable for hanging the door panel 3 to bear the weight of the door panel 3 and the forces generated during the sliding process.

[0095] During the installation process, the installer first firmly connects the first hanging bracket 94 to the outside of the second base 91. Then, they hang or connect the corresponding part of the door panel 3 to the first hanging bracket 94. Since the connection between the first hanging bracket 94 and the second base 91 is firm, the door panel 3 is also stably connected to the second base 91 through the first hanging bracket 94.

[0096] In an embodiment of the present application, a door assembly is provided, as Figures 1 to 4 shown, the first driven sliding door mechanism 1 is arranged at the top of the box door 2, and the door assembly further includes: a second driven sliding door mechanism 18, the second driven sliding door mechanism 18 is arranged at the bottom of the box door 2, the second driven sliding door mechanism 18 is connected to the door panel 3, and during the opening or closing process of the box door 2, the second driven sliding door mechanism 18 cooperates with the first driven sliding door mechanism 9 to guide the door panel 3 to move relative to the width direction of the box door 2.

[0097] Specifically, in this embodiment, the traction member 17, the active sliding door mechanism 1 and the first driven sliding door mechanism 9 are arranged at the top of the box door 2. The second driven sliding door mechanism 18 is arranged at the bottom of the box door 2. During the opening or closing process of the box door 2, the box body 4 drives the active sliding door mechanism 1 through the traction member 17. The active sliding door mechanism 1 drives the first driven sliding door mechanism 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 mechanism 9, so as to avoid interference between the door panel 3 and the external obstacles. During this process, the second driven sliding door mechanism 18 cooperates with the first driven sliding door mechanism 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.

[0098] In this embodiment, through the coordinated work of the active sliding door mechanism 1, the first driven sliding door mechanism 9 and the second driven sliding door mechanism 18, the movement direction of the door panel 3 can be effectively restricted. So that 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.

[0099] In one embodiment, as Figure 8 shown, the second driven sliding door mechanism 18 is a C-shaped drawer track structure, including: a third base 181, a fourth slider 182 and a second hanging bracket 183. A fourth guide rail 1811 is formed inside the third base 181. The fourth slider 182 is slidably arranged (generally inscribed) in the fourth guide rail 1811, and the fourth slider 182 is connected to the box door 2; the second hanging bracket 183 is connected to the outside of the third base 181 for hanging the door panel 3.

[0100] In this embodiment, the inner side of the third base 181 is provided with a fourth guide rail 1811. The fourth slider 182 is connected to the box door 2. The outer side of the third base 181 is connected to the door panel 3 through a second hanger 183. When the door panel 3 moves relative to the box door 2, the third base 181 moves relative to the fourth slider 182 through the fourth guide rail 1811, so as to cooperate with guiding the movement of the door panel 3 and the box door 2.

[0101] Similarly, the second driven sliding door mechanism 18 further includes a second ball support member 184. The second ball support member 184 is slidably internally connected to the fourth guide rail 1811, and the fourth slider 182 is slidably internally connected to the second ball support member 184. With the assistance of the second ball support member 184, the fourth slider 182 slides in the fourth guide rail 1811 with low friction and high efficiency. Due to the presence of the second ball support member 184, the sliding process of the fourth slider 182 becomes more stable and reliable, thus ensuring the stable operation of the entire second driven sliding door mechanism 18. It should be noted that the specific structure of the second ball support member 184 is the same as that of the first ball support member 93, and will not be elaborated here.

[0102] It should be noted that in practical applications, the designs of the first slider 11, the second slider 12, the third slider 92 and the fourth slider 182 can be flexible and variable to adapt to different working scenarios and performance requirements. They are not limited to specific shapes, sizes or materials, but can be customized and optimized according to specific needs.

[0103] From the perspective of materials, the first slider 11, the second slider 12, the third slider 92 and the fourth slider 182 can select materials with high wear resistance, low friction coefficient and good stability, such as metal alloys, engineering plastics or special lubricating materials. The selection of these materials aims to improve the durability of the sliders, reduce wear and noise during the sliding process, and ensure the smoothness of the sliding.

[0104] 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, 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 selecting, factors such as usage conditions, cost-effectiveness and maintenance convenience should be comprehensively considered.

[0105] In another embodiment of the present application, such as Figures 1 to 10As 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.

[0106] By providing a door panel 3 on the box door 2, when the refrigeration device is an in-built type and is arranged in a groove-shaped space or between two cabinet bodies, the door panel 3 can be arranged flush with the side wall of the groove or the cabinet bodies on both sides, so as to reduce the gap between the refrigeration device and the adjacent wall or cabinet body, making it more beautiful.

[0107] At the same time, when the box door 2 rotates, the active sliding door mechanism 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 away as possible from obstacles such as the wall or cabinet body on the side of the side door of the box body 4, so as to prevent these obstacles from blocking the door panel 3 and affecting the rotation of the box door 2, resulting in the box door 2 being unable to be opened or closed normally.

[0108] 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 use convenience. Especially in a narrow kitchen environment, this design advantage is more obvious. In addition, the setting of the slider and guide rail in the active sliding door mechanism 1 enables the door panel 3 to move smoothly during the opening and closing processes, improving the service life and stability of the refrigerator.

[0109] It can be understood that if the door body assembly has the beneficial effects of the above embodiments, the refrigeration device correspondingly has the beneficial effects of the above embodiments. The specific implementation manners can refer to the above embodiments and will not be elaborated in this application.

[0110] In some embodiments, as Figure 9 and Figure 10 shown, the door body assembly and the box body 4 are used to be arranged in an installation space 8 formed between a first cabinet body 6 and a second cabinet body 7. An opening is provided on the outside of the installation space 8. This design enables the door body assembly and the box body 4 to be integrally embedded in 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 mechanism 1 is configured to drive the door panel 3 to move a preset distance in the box door 2 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 body 6 and the second cabinet body 7.

[0111] 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 mechanism 1 is configured to drive the door panel 3 to move a preset distance in the box 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 body 6 and the second cabinet body 7, and in order to enable the door panel 3 to be smoothly opened or closed through the movement of the preset distance without colliding or jamming with the side walls of the cabinet body.

[0112] For example, as Figure 9 and Figure 10 shown, during the opening process of the box door 2, the active sliding door mechanism 1 drives the door panel 3 to move a preset distance along the box door 2 away from the hinge 5. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet body 7, so that the box door 2 can be fully opened, facilitating users to access items.

[0113] Similarly, during the closing process of the box door 2, the active sliding door mechanism 1 drives the door panel 3 to move a preset distance along the box door 2 towards the hinge 5. In this way, the door panel 3 can smoothly avoid the side wall of the first cabinet body 6, so that the box door 2 can be fully closed, maintaining the overall aesthetics and sealing performance.

[0114] In some embodiments, as Figures 1 to 4 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 can be driven to move relative to the corresponding box door 2.

[0115] 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 spaces. The door panel 3 of each door body assembly can also slide relative to the corresponding box door 2. When the box door 2 is closed, the door panel 3 can be flush with the side cabinet body, or when the box door 2 is opened, the door panel 3 can avoid obstacles on both sides.

[0116] Specifically, the box body 4 has a first storage space and a second storage space. Correspondingly, the door body assemblies also include 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.

[0117] Furthermore, the first door body assembly and the second door body assembly are arranged vertically along the height direction of the box door 2. The first door body assembly is provided with an active sliding door mechanism 1, a first driven sliding door mechanism 9, and a second driven sliding door mechanism 18, capable of controlling the corresponding movement of the corresponding door panel 3 and the box door 2 by using the corresponding active sliding door mechanism 1, first driven sliding door mechanism 9, and second driven sliding door mechanism 18. The second door body assembly is provided with an active sliding door mechanism 1, a first driven sliding door mechanism 9, and a second driven sliding door mechanism 18, capable of controlling the corresponding movement of the corresponding door panel 3 and the box door 2 by using the corresponding active sliding door mechanism 1, first driven sliding door mechanism 9, and second driven sliding door mechanism 18.

[0118] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model, rather than limiting the present utility model. Although the present utility model 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 substitutions of the technical solutions of the present utility model do not depart from the spirit and scope of the technical solutions of the present utility model, and should all be covered within the scope of the claims of the present utility model.
