Description

Technical Field

[0063] The following will describe the door body assembly and the refrigeration device of the present application in conjunction with Figures 1 to 12 The door body assembly in the present application can be applied to the door 2 of a household electrical appliance or a cabinet door, etc., such as the door 2 of a refrigerator. However, it should be understood that the door body assembly of the present application can also be applied to any other suitable device. The refrigeration device in the present application is, for example, applied as a refrigerator. However, it should be understood that the refrigeration device of the present application can also be applied as a freezer or any other suitable device.

[0064] In one embodiment of the present application, as Figures 1 to 4 shown, the door body assembly is applied to a refrigeration device. The refrigeration device includes a box body 4. The door body assembly includes: an active sliding door mechanism 1, a first driven sliding door mechanism 9, a door 2, and a door panel 3. The door 2 is rotatably connected to the box body 4. The 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 door 2.

[0065] In this embodiment, the active sliding door mechanism 1 and the first driven sliding door mechanism 9 are disposed on the door 2. The box body 4 is in transmission connection with the active sliding door mechanism 1. The door panel 3 is in transmission connection with the active sliding door mechanism 1. The door panel 3 is in transmission connection with the first driven sliding door mechanism 9. The position where the active sliding door mechanism 1 is connected to the door panel 3 is higher than the position where the first driven sliding door mechanism 9 is connected to the door panel 3. During the opening or closing process of the door 2, the box body 4 drives the active sliding door mechanism 1, and the active sliding door mechanism 1 drives the door panel 3 to move relative to the width direction of the door 2; the first driven sliding door mechanism 9 bears the door panel 3 and cooperates with the active sliding door mechanism 1 to guide the door panel 3 to move relative to the width direction of the door 2.

[0066] In this embodiment, the box body 4 is the main part of the refrigeration device. A storage space is provided inside the box body 4 for storing food or other items that need to be refrigerated or frozen. The door 2 is hinged to the box body 4 through 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 is an additional, slidable component disposed outside the door 2.

[0067] In this embodiment, when the door 2 is opened or closed, the box body 4 transmits power to the active sliding door mechanism 1. The active sliding door mechanism 1 drives the door panel 3 to move relative to the width direction of the door 2, thereby preventing the door panel 3 from interfering with obstacles outside.

[0068] Since the position where the active sliding door mechanism 1 is connected to the door panel 3 is higher than the position where the first driven sliding door mechanism 9 is connected to the door panel 3, the active sliding door mechanism 1 does not directly bear the weight of the door panel 3 in the vertical direction. However, the first driven sliding door mechanism 9 closely cooperates with the active sliding door mechanism 1, and the first driven sliding door mechanism 9 bears the gravity of the door panel 3 in the vertical direction, so that when the door 2 is opened or closed, the active sliding door mechanism 1 can be prevented from bearing external forces in other directions, thereby reducing the problem of the door panel 3 shaking when it moves relative to the door 2.

[0069] According to the door 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 active sliding door mechanism is connected to the box body in a transmission manner, and the first driven sliding door mechanism is connected to the door panel, so that the box body drives the door panel to move relative to the width direction of the box door through the active 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 position where the active sliding door mechanism in the door assembly is connected to the door panel is higher than the position where the first driven sliding door mechanism is connected to the door panel, so that the active sliding door mechanism that directly drives the door panel does not bear the weight of the door panel, while the first driven sliding door mechanism bears the door panel and cooperates with the active sliding door mechanism to guide the door panel to move relative to the width direction of the box door, 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 3 As shown, the door assembly further includes: a first hook 31 and a second hook 32. The first hook 31 is connected to the door panel 3 for being hooked on the active sliding door mechanism 1; the second hook 32 is connected to the door panel 3 for being hooked on the first driven sliding door mechanism 9; wherein the installation position of the first hook 31 on the door panel 3 is higher than the installation position of the second hook 7 on the door panel 3.

[0071] In this embodiment, the first hook 31 and the second hook 32 not only ensure the stable connection between the door panel 3 and the active sliding door mechanism 1 and the first driven sliding door mechanism 9, but also clearly distinguish the functional roles they assume. The first hook 31 is located at a higher position and is used to be hooked on the active sliding door mechanism 1. It is not completely connected to the active sliding door mechanism 1. It is mainly responsible for transmitting the power from the box body 4, driving the door panel 3 to move smoothly along the width direction of the box door 2, and effectively avoiding possible obstacles. The second hook 32 is installed at a relatively low position and connected to the first driven sliding door mechanism 9. It not only serves as a connection point, but more importantly, it carries the weight of the door panel 3 in the vertical direction, thereby sharing the load of the active sliding door mechanism 1 and preventing it from causing unnecessary shaking or wear due to additional force during operation. As a result, not only the overall stability and durability of the door assembly are improved, but also the smoothness and convenience of the user during use are ensured.

[0072] In some embodiments, Figures 1 to 3 As shown, there are multiple first driven sliding door mechanisms 9, and the multiple first driven sliding door mechanisms 9 and the active sliding door mechanism 1 are coaxially arranged on the box door 2, and multiple second hooks 32 are correspondingly arranged, and each first driven sliding door mechanism 9 is drivingly connected to the door panel 3 through the corresponding second hook 32. It should be noted that the "coaxial arrangement" here allows a certain error range (±5°), which is to take into account the deviation in the actual installation and manufacturing process.

[0073] In this embodiment, the first driven sliding door mechanism 9 is provided in plurality, and the plurality of first driven sliding door mechanisms 9 are coaxially arranged on the box door 2 together with the active sliding door mechanism 1, thereby reducing the imbalance problem caused by the offset of a single mechanism. At the same time, in order to realize this multi-point connection transmission mechanism, the second hook 32 is also correspondingly designed in plurality, and each second hook 32 precisely corresponds to and is connected to a first driven sliding door mechanism 9, thereby ensuring a tight and stable transmission connection between the door panel 3 and the first driven sliding door mechanism 9.

[0074] Similarly, the first hook 31 is located at a relatively high position and is connected to the active sliding door mechanism 1. It is mainly responsible for transmitting the power from the box body 4, driving the door panel 3 to move smoothly along the width direction of the box door 2, and effectively avoiding possible obstacles. The multiple second hooks 32 are installed at a relatively low position and connected to the corresponding first driven sliding door mechanism 9 to bear the weight of the door panel 3 in the vertical direction, thereby sharing the load of the active sliding door mechanism 1 and preventing the active sliding door mechanism 1 from unnecessary shaking or wear due to additional force during operation. The multiple first driven sliding door mechanisms 9 bear the weight of the door panel 3 through the second hooks 32, reducing the weight borne by a single first driven sliding door mechanism 9 and improving the stability of the door assembly during movement.

[0075] In some embodiments,Figure 4 As shown in the figure, 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. One side of the first base 13 is formed with a first guide rail 131, and the other side is formed with a second guide rail 132. 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 arranged 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 arranged on the second guide rail 132 and is in transmission connection with the door panel 3; both 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 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.

[0076] 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 respectively formed on the upper side and the lower side thereof. 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 door panel 3 and is used to drive the door panel 3 to move. The flexible cable 14 can be a connecting member 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. The position where the second slider 12 is hooked to the door panel 3 is higher than the position where the first driven sliding door mechanism 9 is hooked to the door panel 3. Therefore, the second slider 12 itself does not bear the gravity of the door panel 3 (or bears a small force). Rely on the first driven sliding door mechanism 9 to bear the weight of the entire door panel 3 and reduce the problem of shaking when the door panel 3 moves relative to the box door 2.

[0077] During the process of the box door 2 rotating outward to open towards the box body 4, the box body 4 drives the first slider 11 to slide towards the direction close to the hinge 5 through the traction member 17. At the same time, the first slider 11 drives the second slider 12 to slide in the opposite direction through the flexible cable 14, and uses the second slider 12 to drive the door panel 3 to move, thereby avoiding interference between the door panel 3 and the outer obstacles. During the process of the box door 2 rotating towards the box body 4 to close, the box body 4 drives the first slider 11 to slide away from the hinge 5 through the traction member 17. At the same time, the first slider 11 drives the second slider 12 to slide in the opposite direction through the flexible cable 14, and uses the second slider 12 to drive the door panel 3 to move, avoiding interference between the closed door panel 3 and the obstacles.

[0078] In some embodiments, such as Figure 4As 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.

[0079] In this embodiment, by bypassing one end of the first base 13 with the first flexible cable and connecting it to the first slider 11 and the second slider 12 respectively, when the first slider 11 slides away from this end of the first base 13 under the drive of the box body 4, the first slider 11 drives the second slider 12 to slide towards this end of the first base 13 through the first flexible cable; at the same time, by bypassing the other end of the first base 13 with the second flexible cable and connecting it to the first slider 11 and the second slider 12 respectively, when the first slider 11 slides away from this 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 this 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 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 affect the opening and closing of the box door 2.

[0080] In some embodiments, as Figure 4 shown, the active sliding door mechanism 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 butted against one ends of the first guide rail 131 and the second guide rail 132, and a part of the first flexible cable is slidably arranged in the first limiting groove; the second 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 butted against 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 arranged in the second limiting groove.

[0081] Specifically, the first fixing seat 15 is connected to one end of the first base 13, serving as an extension and support for the first guide rail 131 and the second guide rail 132 at this end. A first limiting groove is formed on the first fixing seat 15. The first limiting groove not only provides an additional sliding track for the first flexible cable but also ensures the stability and accuracy of the first flexible cable during the sliding process. Both ends of the first limiting groove are docked with one end of the first guide rail 131 and the second guide rail 132. The existence of the first limiting groove restricts the offset and sway of the first flexible cable during the sliding process, improving the operating precision and reliability of the entire active sliding door mechanism 1. The second fixing seat 16 corresponds to the first fixing seat 15. The second fixing seat 16 is connected to the other end of the first base 13, providing support and extension for the first guide rail 131 and the second guide rail 132 at this end. A second limiting groove is formed on the second fixing seat 16, and its design is similar to that of the first limiting groove but is located at the other end of the active sliding door mechanism 1. Both ends of the second limiting groove are docked with the other end of the first guide rail 131 and the second guide rail 132, providing guidance and limitation for the sliding of the second flexible cable. Similar to the first limiting groove, the second limiting groove also plays a role in restricting the offset and sway of the flexible cable 14.

[0082] To install the active slider mechanism, in some embodiments, as Figure 4 shown, fixing holes are provided on the first fixing seat 15 and / or the second fixing seat 16. The active sliding door mechanism 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 mechanism 1 can be fixed on the box door 2.

[0083] In this embodiment, by fixing the first fixing seat 15 and / or the second fixing seat 16 connected to the first base 13 on the box door 2 through the fixing members, it can be ensured that the mechanism will not loosen or shift due to external forces or vibrations during operation. The design of the fixing holes and the fixing members makes the installation process simple and fast. The operator only needs to align the fixing members with the fixing holes and tighten them to complete the connection between the active sliding door 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 the need for complex disassembly work. This greatly improves the maintainability and flexibility of the equipment.

[0084] In specific implementation, appropriate fixing members, 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 fixing members to ensure the firmness and stability of the connection.

[0085] In some embodiments, as Figure 5 、 Figure 6 and Figure 7As shown, the first driven sliding door mechanism 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 is connected to the door panel 3, and the position where the second slider 12 is connected to the door panel 3 is higher than the position where the third slider 92 and / or the fourth slider 93 is connected to the door panel 3.

[0086] In this embodiment, the third guide rail 911 is provided on the upper side of the second base 91, and the fourth guide rail 912 is provided on the lower side of the second base 91. 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. The door panel 3 is hung on the third slider 92 and the fourth slider 93, so as to be able to guide the door panel 3 to move relative to the width direction of the box door 2.

[0087] In this embodiment, by setting double sliders, it is possible to avoid the single slider from bearing too much weight of the door panel 3, thereby improving the stability during the movement process.

[0088] In some embodiments, as Figure 5 , Figure 6 and Figure 7 shown, the first driven sliding door mechanism 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 forms a first limiting notch; the second support frame 95 is disposed between the fourth slider 93 and the fourth guide rail 912 and forms a second limiting notch; the first ball 96 is rotatably disposed in the first limiting notch, and both sides of the first ball 96 are in contact with the third slider 92 and the third guide rail 911; the second ball 97 is rotatably disposed in the second limiting notch, and both sides of the second ball 97 are in contact with the fourth slider 93 and the fourth guide rail 912.

[0089] In this embodiment, the first support frame 94 is disposed 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 for accommodating the first ball 96 and restricting its rolling range. The first limiting notch ensures that the first ball 96 does not break away from the first support frame 94 during the rolling process, and at the same time provides a certain rolling space for the first ball. The first balls are rollably disposed in the first limiting notch, with one side thereof abutting against the third guide rail 911 and the other side passing through the first limiting notch and abutting against the third slider 92. This design enables the third slider 92, when sliding, not to directly contact the third guide rail 911 and generate sliding friction, but to achieve sliding through the rolling of the first balls 96. This method greatly reduces the frictional resistance during the sliding process and improves the sliding efficiency. Since the rolling of the first balls 96 is of low friction, it can significantly reduce the wear between the third slider 92 and the third guide rail 911. This helps to extend the service life of these two components and reduce the maintenance cost.

[0090] Similarly, the second support frame 95 is disposed between the fourth guide rail 912 and the fourth slider 93. It is used to ensure that the second balls 97 can roll in the correct position, thereby supporting the sliding of the fourth slider 93. The second support frame 95 is designed with a second limiting notch, which is for accommodating the second balls 97 and restricting their rolling range. The second limiting notch ensures that the second balls 97 do not break away from the second support frame 95 during the rolling process.

[0091] In summary, in this embodiment, the combined design of balls and support frames is adopted to achieve 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, effectively improving the sliding efficiency.

[0092] In some embodiments, as Figures 5 to 6 shown, the first driven sliding door mechanism 9 includes: a second base 91 and a third slider 92. One side of the second base 91 forms a third guide rail 911, and the other side forms a fourth guide rail 912. The third slider 92 is slidably disposed on the third guide rail 911 and the fourth guide rail 912 and is connected to the door panel 3.

[0093] In this embodiment, a single-slider setting is adopted, and a single third slider 92 is simultaneously disposed on the third guide rail 911 and the fourth guide rail 912. The third slider 92 is connected to the door panel 3, so that when the door panel 3 moves, the door panel 3 can drive the third slider 92 to move. By adopting the single-slider setting in this embodiment, compared with the double-slider solution, the structure of the entire component can be simplified.

[0094] For facilitating the hanging of the door panel 3, as Figures 1 to 4As shown, the active sliding door mechanism 1 also includes: a first bracket; the first driven sliding door mechanism 9 also includes: a second bracket 98; the first bracket is arranged on the second slider 12, and the second bracket 98 is arranged on the third slider 92 and / or the fourth slider 93, and the height of the first bracket is lower than the height of the second bracket 98.

[0095] It is worth noting that the design height of the first bracket is intentionally set lower than the second bracket 98. Such a design decision is based on multiple considerations: First, it ensures that when the door panel 3 is hung, the door panel 3 can first contact and initially fix with the second bracket 98 at a higher position, and the door panel 3 will not be stably connected through the first bracket, so that the gravity of the door panel 3 itself is completely borne by the second bracket 98, and the first bracket only pulls the door panel 3 in the horizontal direction. Therefore, the first driven sliding door mechanism 9 bears the weight of the door panel 3 in the vertical direction, shares the load of the active sliding door mechanism 1, and prevents the active sliding door mechanism 1 from unnecessary shaking or wear due to additional force during operation. As a result, not only the overall stability and durability of the door assembly are improved, but also the smoothness and convenience of the user during use are ensured.

[0096] In one embodiment of the present application, a door assembly is provided, such as Figures 1 to 4 As shown, the first driven sliding door mechanism 9 and the active sliding door mechanism 1 are arranged at the top end of the box door 2, and the door body assembly also includes: a second driven sliding door mechanism 18, the second driven sliding door mechanism 18 is arranged at the bottom end of the box door 2, and the second driven sliding door mechanism 18 is connected to the door panel 3. 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, during the opening or closing of the door 2, the box body 4 drives the door panel 3 through the active sliding door mechanism 1, so as to drive the door panel 3 to move in the width direction relative to the door 2 through the active sliding door mechanism 1, thereby avoiding interference between the door panel 3 and obstacles outside. In 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 in the width direction relative to the door 2, which can effectively improve the stability during movement.

[0098] In this embodiment, the active sliding door mechanism 1, the first driven sliding door mechanism 9, and the second driven sliding door mechanism 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.

[0099] like Figure 1 and Figure 2As shown in the figure, a first end cover 21 is provided at the top of the box door 2. An installation groove for arranging the active sliding door mechanism 1 and the first driven sliding door mechanism 9 is provided on the first end cover 21. According to the specific shapes of the traction member 17, the active sliding door mechanism 1, and the first driven sliding door mechanism 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 of the box door 2. An installation groove for arranging the second driven sliding door mechanism 18 is provided on the second end cover 22. According to the shape of the second driven sliding door mechanism 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.

[0100] In one embodiment, as Figure 8 , Figure 9 and Figure 10 shown, the second driven sliding door mechanism 18 includes: a third base 181 and 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 box door 2; a third hanger 183 is connected to the outside of the third base 181 for hanging the door panel 3.

[0101] In this embodiment, the fifth guide rail 1811 is provided on the inner side of the third base 181, the fifth slider 182 is connected to the box 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 box door 2, the third base 181 moves relative to the fifth slider 182 through the fifth guide rail 1811, so as to be able to cooperate with guiding the movement of the door panel 3 and the box door 2.

[0102] In this embodiment, the third hanger 183 serves as the hanging point of the door panel 3, making the installation of the door panel 3 simpler and faster, because the installer only needs to hang the door panel 3 on the first hanger, the second hanger 98, and the third hanger 183, without the need for complex fixing or connecting operations.

[0103] It should be noted that in actual 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.

[0104] 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 sliding.

[0105] 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 planar contact, ball contact, or sliding bearing contact, etc. These different contact methods have their own advantages and disadvantages. For example, ball contact can reduce friction and wear, but the cost is relatively high; while planar contact has a simple structure, but may require more frequent lubrication and maintenance. Therefore, when making a choice, factors such as usage conditions, cost-effectiveness, and maintenance convenience should be comprehensively considered.

[0106] In an embodiment of another aspect of the present application, as Figures 1 to 12 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.

[0107] By providing a door panel 3 on the box door 2, when the refrigeration device is an inlaid type and is disposed in a groove-shaped space, or is disposed between two cabinet bodies, the door panel 3 can be set 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.

[0108] Meanwhile, 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 box body 4 of the side door, 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.

[0109] 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 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.

[0110] 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.

[0111] In some embodiments, such as Figure 11 and Figure 12As shown, the door body assembly and the box body 4 are used to be arranged in 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 that the box door 2 passes 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 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 can avoid the side walls of the first cabinet body 6 and the second cabinet body 7.

[0112] During the process that the box door 2 passes 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 on the box door 2 to move a preset distance 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 smoothly open or close through the movement of the preset distance without colliding with or jamming against the side walls of the cabinet body.

[0113] For example, as Figure 11 and Figure 12 shown, during the process of opening 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 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, which is convenient for users to store and retrieve items.

[0114] Similarly, during the process of closing 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 in a direction close to 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.

[0115] 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 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.

[0116] 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, which is convenient for users to store or retrieve items in the storage space. The door panel 3 of each door body assembly can also slide relative to the corresponding box door 2. When the box door 2 is closed, the door panel 3 can be flush with the side cabinet body, or when the box door 2 is opened, the door panel 3 can avoid the obstacles on both sides.

[0117] 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.

[0118] 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 mechanism 1, a first driven sliding door mechanism 9, and a second driven sliding door mechanism 18. The corresponding door panel 3 and the box door 2 can be controlled to move correspondingly by using the corresponding active sliding door mechanism 1, the first driven sliding door mechanism 9, and the 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. The corresponding door panel 3 and the box door 2 can be controlled to move correspondingly by using the corresponding active sliding door mechanism 1, the first driven sliding door mechanism 9, and the second driven sliding door mechanism 18.

[0119] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered by the scope of the claims of the present invention.
