[0058] The following is combined with Figures 1 to 9 to describe the door body assembly and refrigeration equipment of this application. The door body assembly in this application can be applied to the door 2 of household appliances, cabinet doors, etc., such as the door 2 of a refrigerator. However, it should be understood that the door body assembly of this application can also be applied to any other suitable equipment. The refrigeration equipment in this application is, for example, applied as a refrigerator. However, it should be understood that the refrigeration equipment of this application can also be applied as a freezer or any other suitable equipment.

[0059] In one embodiment of this application, as Figures 1 to 4 shown, this door body assembly is applied to a refrigeration equipment. The refrigeration equipment 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, a hanging bracket 5 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 arranged outside the door 2.

[0060] In this embodiment, the active sliding door mechanism 1 is arranged on the box door 2. The hanging bracket 5 includes a support plate 53, a first positioning strip 51 and a second positioning strip 52. The hanging bracket 5 has an adjustable form and a fixed form. When the hanging bracket 5 is in the adjustable form, one end of the first positioning strip 51 is hung on the top surface of the door panel 3, and the other end of the first positioning strip 51 is slidably connected to the support plate 53. One end of the second positioning strip 52 is hung on the side surface of the door panel, and the other end of the second positioning strip 52 is slidably connected to the support plate 53. The support plate 53 is movably connected to the active sliding door mechanism 1 to adjust the position where the door panel 3 is connected to the active sliding door mechanism 1. When the hanging bracket 5 is in the fixed form, the door panel 3 is fixedly connected to the active sliding door mechanism 1 through the support plate 53. During the opening or closing process of the box 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 box door 2.

[0061] 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 box door 2 is hinged to the box body 4 through a hinge and can rotate around one or more pivot points to open and close the storage space. The door panel 3 is an additional, slidable component arranged on the outer side of the box door 2.

[0062] During the installation process of the door panel 3, the hanging bracket 5 is in the adjustable form. One end of the first positioning strip 51 is hung on the top surface of the door panel 3, and the other end is slidably connected to the support plate 53. One end of the second positioning strip 52 is hung on the side surface of the door panel 3, and the other end is slidably connected to the support plate 53. Thus, the relative position between the support plate 53 and the door panel 3 in the height direction can be adjusted through the relative position between the first positioning strip 51 and the support plate 53, and the relative position between the support plate 53 and the door panel 3 in the left - right direction can be adjusted through the relative position between the second positioning strip 52 and the support plate 53. At the same time, the support plate 53 is also movably connected to the active sliding door mechanism 1. The hanging bracket 5 can not only adjust its position relative to the door panel 3 through the first positioning strip 51 and the second positioning strip 52, but also adjust its position relative to the active sliding door mechanism 1, so as to facilitate the user to adjust the installation position of the door panel 3.

[0063] When the door panel 3 is actually installed, first, the support plate 53 is arranged on the door panel 3 through the first positioning strip 51 and the second positioning strip 52, and the position of the support plate 53 is adjusted through the first positioning strip 51 and the second positioning strip 52. Then, the support plate 53 is connected to the active sliding door mechanism 1, and the positions of the support plate 53 and the active sliding door mechanism 1 are adjusted. At the same time, the position of the support plate 53 is adjusted through the first positioning strip 51 and the second positioning strip 52, so that the relative position between the door panel 3 and the active sliding door mechanism 1 can be adjusted, facilitating the installation of the door panel 3. After the installation of the door panel 3 is completed, the hanging bracket 5 is in a fixed state, and the positions of the hanging bracket 5, the door panel 3, and the active sliding door mechanism 1 are fixed. The door panel 3 is fixedly connected to the active sliding door mechanism 1 through the support plate 53. At this time, when the box door 2 is opened or closed, the box body 4 can drive the active sliding door mechanism 1, and the active sliding door mechanism 1 can drive the door panel 3 to move relative to the width direction of the box door 2, so that the door panel 3 can avoid obstacles on both sides.

[0064] Generally, there are at least two first positioning strips 51 to ensure the stability between the support plate 53 and the door panel 3 when the support plate 53 is not connected to the door panel 3.

[0065] According to the door body assembly of the present application, there are an active sliding door mechanism, a hanging bracket, a box door, and a door panel. During the installation of the door panel, the hanging bracket is in an adjustable state. One end of the first positioning strip is hung on the top surface of the door panel, and the other end is slidably connected to the support plate; one end of the second positioning strip is hung on the side surface of the door panel, and the other end is slidably connected to the support plate. The support plate is movably connected to the active sliding door mechanism. The hanging bracket can not only adjust its position relative to the door panel through the first positioning strip and the second positioning strip, but also adjust its position relative to the active sliding door mechanism, so that the user can conveniently adjust the installation position of the door panel. After the installation of the door panel is completed, the hanging bracket is in a fixed state, and the positions of the hanging bracket, the door panel, and the active sliding door mechanism are fixed. The door panel is fixedly connected to the active sliding door mechanism through the support plate. At this time, when the box door is opened or closed, the box body can drive the active sliding door mechanism, and the active sliding door mechanism can drive the door panel to move relative to the width direction of the box door, so as to avoid the interference problem during the door opening process.

[0066] In some embodiments, as Figure 3 and Figure 4 shown, the support plate 53 is configured with a first chute arranged along the vertical direction of the support plate and a second chute arranged along the horizontal direction of the support plate 53; when the hanging bracket 5 is in an adjustable state, the first positioning strip 51 is slidably arranged in the first chute, and the second positioning strip 52 is slidably arranged in the second chute; when the hanging bracket 5 is in a fixed state, the first positioning strip 51 is separated from the first chute, and the second positioning strip 52 is separated from the second chute.

[0067] Specifically, the support plate 53 is provided with a plurality of groups of first protrusion structures arranged in the vertical direction, each group of first protrusion structures is provided with two opposite first protrusions 531, and the opposite first protrusions 531 in the plurality of groups of first protrusion structures form a first slide groove. The support plate 53 is provided with a plurality of groups of second protrusion structures arranged in the horizontal direction, each group of second protrusion structures is provided with two opposite second protrusions 532, and the opposite second protrusions 532 in the plurality of groups of second protrusion structures form a second slide groove.

[0068] When the door panel 3 is actually installed, the hanger 5 is in an adjustment state. By sliding the first positioning strip 51 in the first slide groove, the relative position of the door panel 3 and the support plate 53 in the height direction can be adjusted. By sliding the second positioning strip 52 in the second slide groove, the relative position of the door panel 3 and the support plate 53 in the horizontal direction can be adjusted. After the door panel 3 is installed, the support plate 53 can be fixed to the door panel 3 by screws, and the first positioning strip 51 can be taken out of the first slide groove, and the second positioning strip can be taken out of the second slide groove. The hanger 5 is in a fixed state, and the positions of the hanger 5, the door panel 3 and the active sliding door mechanism 1 are fixed, and the door panel 3 is fixedly connected to the active sliding door mechanism 1 through the support plate 53. At this time, if the box door 2 is opened or closed, the box body 4 can drive the active sliding door mechanism 1, and the active sliding door mechanism 1 can drive the door panel 3 to move relative to the width direction of the box door 2, so that the door panel 3 avoids obstacles on both sides.

[0069] In order to ensure the stability of the entire rack 5 during the adjustment process, Figure 3 and Figure 4 As shown, the first positioning bar 51 is provided with a first rack, and the second positioning bar 52 is provided with a second rack; the first slide groove is provided with a first stopper 54 extending to abut against the first rack, and the second slide groove is provided with a second stopper 55 abutting against the second rack. By providing the first stopper 54, it can extend to closely abut against the first rack, effectively preventing the first positioning bar 51 from accidentally shifting or shaking during the sliding process, and enhancing the stability of the vertical direction adjustment. Similarly, the second stopper 55 is also installed in the second slide groove, which closely cooperates with the second rack to ensure the stability and accuracy of the horizontal direction adjustment.

[0070] In some embodiments, Figures 1 to 5 As shown, the door body assembly also includes: a first driven sliding door mechanism 9 and a transmission rod 19, the first driven sliding door mechanism 9 is arranged on the box door 2, the first driven sliding door mechanism 9 is transmission-connected to the active sliding door mechanism 1 through the transmission rod 19, and the first driven sliding door mechanism 9 is connected to the door panel 3; during the opening or closing process of the box door 2, the active sliding door mechanism 1 drives the first driven sliding door mechanism 9 through the transmission rod 19, so as to drive the door panel 3 to move relative to the width direction of the box door 2 through the active sliding door mechanism 1 and the first driven sliding door mechanism 9.

[0071] 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 mechanism 1. The active sliding door mechanism 1 drives the first driven sliding door mechanism 9 through the transmission rod 19, so as to drive the door panel 3 to move relative to the width direction of the door 2 through the active sliding door mechanism 1 and 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 cooperates with the first driven sliding door mechanism 9 to bear the weight of the door panel 3, so that during the process of opening or closing the door 2, the gravity borne by the active sliding door mechanism 1 can be reduced.

[0072] According to the door body assembly provided in the embodiment, a sliding door device including a traction component 17, an active sliding door mechanism 1, and a first driven sliding door mechanism 9 is set on the box door 2, and the active sliding door mechanism 1 is transmission-connected to the box body 4, and the first driven sliding door mechanism 9 is transmission-connected to the active sliding door mechanism 1 through a transmission rod 19, so that 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 through the transmission rod 19, and the door panel 3 is driven to move relative to the width direction of the box door 2 through the first driven sliding door mechanism 9 and the active sliding door mechanism 1, so that the door panel 3 avoids obstacles on both sides and solves the interference problem in the door opening process.

[0073] In order to adjust the front and rear positions and relative heights of the support plate 53 and the transmission rod 19, as shown in FIG. Figure 3 and Figure 4 As shown, the support plate 53 is provided with a first waist-shaped hole 533 extending along its thickness direction, the first waist-shaped hole 533 is provided with a first adjusting member 534, and the transmission rod 19 is provided with a first fixing hole; the first adjusting member 534 passes through the first fixing hole and is slidably arranged in the first waist-shaped hole 533, so as to adjust the relative position of the support plate 53 and the transmission rod 19 (mainly adjusting the front and rear position and relative height) through the position of the first adjusting member 534 in the first waist-shaped hole 533, and the relative position of the first adjusting member 534, the first fixing hole and the first waist-shaped hole.

[0074] Specifically, a first waist-shaped hole 533 extending along the thickness direction of the support plate 53 is formed on the support plate 53. The design of this waist-shaped hole allows a large adjustment range, enabling the user to adjust the position of the support plate 53 according to actual needs. On the first waist-shaped hole 533, a first adjusting member 534 is installed, and this adjusting member can be a bolt, a pin or other similar fasteners. At the same time, a first fixing hole matching the first adjusting member 534 is provided on the transmission rod 19. This fixing hole is used to receive and fix the first adjusting member 534, thereby establishing a connection between the support plate 53 and the transmission rod 19. During the adjustment process, the user can change the relative position between the support plate 53 and the transmission rod 19 by moving the position of the first adjusting member 534 in the first waist-shaped hole 533. Due to the design of the waist-shaped hole, fine adjustment can be performed within a certain range. At the same time, by adjusting the relative position between the first adjusting member 534 and the first fixing hole, the user can further precisely control the relative height between the support plate 53 and the transmission rod 19 to ensure that the subsequent door panel 3 can maintain a stable and accurate trajectory during the sliding process.

[0075] Further, in order to adjust the left and right positions of the transmission rod 19, the active sliding door mechanism 1 and the first driven sliding door mechanism 9, as Figure 3 and Figure 4 shown, a second waist-shaped hole 191 extending along the length direction of the transmission rod 19 is provided on the transmission rod 19. A second adjusting member 192 is provided on the second waist-shaped hole 191, and second fixing holes are provided on both the active sliding door mechanism 1 and the first driven sliding door mechanism 9; the second adjusting member 192 passes through the second fixing hole and is slidably arranged in the second waist-shaped hole 191 to adjust the relative position between the transmission rod 19, the active sliding door mechanism 1 and the first driven sliding door mechanism 9 by the position of the second adjusting member 192 in the second waist-shaped hole 191.

[0076] Specifically, a second waist-shaped hole 191 is formed along the length direction of the transmission rod 19. The design of the second waist-shaped hole 191 allows the transmission rod 19 to be adjusted in position within a certain range in the left-right direction. On the second waist-shaped hole 191, a second adjusting member 192 is installed. The second adjusting member 192 can also be a bolt, a pin or other fasteners, which is used to realize the connection and adjustment between the transmission rod 19 and the active sliding door mechanism 1 and the first driven sliding door mechanism 9. Both the active sliding door mechanism 1 and the first driven sliding door mechanism 9 are provided with second fixing holes that match the second adjusting member 192. The second fixing holes are used to receive and fix the second adjusting member 192, thereby establishing the connection between the transmission rod 19 and these two mechanisms. During the adjustment process, the user can change the relative positions between the transmission rod 19 and the active sliding door mechanism 1 and the first driven sliding door mechanism 9 by moving the position of the second adjusting member 192 in the second waist-shaped hole 191. Due to the design of the second waist-shaped hole 191, this adjustment is continuous and can be finely adjusted within a certain range to meet the requirements under different installation conditions.

[0077] In some embodiments, as Figures 3 to 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. The first base 13 is connected to the box door 2, with a first guide rail 131 formed on one side and a second guide rail 132 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 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, is in transmission connection with the first driven sliding door mechanism 9 through the transmission rod 19, and is connected to the door panel 3 through the transmission rod 19 and the support plate 53; 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.

[0078] In this embodiment, the first base 13 is fixed on the door 2 of the cabinet, and a first guide rail 131 and a second guide rail 132 are respectively formed on its upper side and lower side. 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 cabinet body 4 through a traction member 17, and is driven by the cabinet 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 the second slider 12 is connected to the door panel 3 through a transmission rod 19 and a support plate 53 for driving the door panel 3 to move. The flexible cable 14 can be a connecting member such as a traction rope or a transmission belt. The two ends of the flexible cable 14 are respectively connected to the first slider 11 and the second slider 12, so that the first slider 11 can drive the second slider 12 to move synchronously and move in opposite directions.

[0079] During the process of the door 2 of the cabinet rotating outward to open with respect to the cabinet body 4, the cabinet body 4 drives the first slider 11 to slide in the direction close to the hinge 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 the second slider 12 is used in cooperation with the transmission rod 19 and the support plate 53 to drive the door panel 3 to move, thereby avoiding interference between the door panel 3 and external obstacles. During the process of the door 2 of the cabinet rotating to close to one side of the cabinet body 4, the cabinet body 4 drives the first slider 11 to slide in the direction away from the hinge 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 the second slider 12 is used in cooperation with the transmission rod 19 and the support plate 53 to drive the door panel 3 to move, avoiding interference between the door panel 3 and obstacles after closing.

[0080] In some embodiments, as Figures 3 to 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 end 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 end of the first slider 11 and the second slider 12.

[0081] In this embodiment, by passing the first flexible cable around one end of the first base 13 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; meanwhile, by passing the second flexible cable around the other end of the first base 13 and connecting it to the first slider 11 and the second slider 12 respectively, when the first slider 11 slides away from the other end of the first base 13 under the drive of the box door 2, the first slider 11 drives the second slider 12 to slide towards the other end of the first base 13 through the second flexible cable, so that 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 enables 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.

[0082] In some embodiments, as Figures 3 to 5 shown, the active sliding door mechanism 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 a first limiting groove is formed. Both ends of the first limiting groove are docked 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 a second limiting groove is formed. 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, and a part of the second flexible cable is slidably disposed in the second limiting groove.

[0083] Specifically, the first fixing seat 15 is connected to one end of the first base 13, serving 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 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 presence of the first limiting groove limits 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 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 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 limiting the offset and sway of the flexible cable 14.

[0084] In order to install the active sliding door mechanism, in some embodiments, as Figure 4 shown, the first fixed seat 15 and / or the second fixed seat 16 are provided with fixing holes, and the active sliding door mechanism 1 further includes a fixing member that passes through the fixing holes to connect with the cabinet door 2, so that the entire active sliding door mechanism 1 can be fixed on the cabinet door 2.

[0085] In this embodiment, by fixing the first fixed seat 15 and / or the second fixed seat 16 connected to the first base 13 on the cabinet door 2 through the fixing member, it can be ensured that the mechanism will not loosen or shift due to external force or vibration during operation. The design of the fixing holes and the fixing member makes the installation process simple and fast. The operator only needs to align the fixing member with the fixing hole and tighten it to complete the connection between the active sliding door mechanism 1 and the cabinet 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 cabinet door 2 only by removing the fixing member, without the need for complex disassembly work. This greatly improves the maintainability and flexibility of the equipment.

[0086] In specific implementation, appropriate fixing members can be selected according to the structure and material of the cabinet door 2, such as screws, bolts, rivets, etc. 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.

[0087] In some embodiments, as Figures 3 to 5 shown, the first driven sliding door mechanism 9 includes: a second base 91 and a third slider 92. The second base 91 is connected to the cabinet door 2, and a third guide rail 911 is formed on one side; the third slider 92 is slidably disposed on the third guide rail 911, the third slider 92 is connected to the second slider 12 through a transmission rod 19, and the third slider 92 is connected to the door panel 3 through the transmission rod 19 and a support plate 53.

[0088] In this embodiment, the third guide rail 911 is provided on the upper side of the second base 91. The third slider 92 can move on the third guide rail 911. Since the third slider 92 is connected to the door panel 3 in cooperation with the transmission rod 19 and the support plate 53, it can cooperate with the active sliding door mechanism 1 to guide the door panel 3 to move in the width direction relative to the cabinet door 2.

[0089] In an embodiment of the present application, a door body assembly is provided, such as Figure 1 and Figure 2As shown, there are two hanging brackets 5, namely the first hanging bracket 56 and the second hanging bracket 57. The first driven sliding door mechanism 9 and the active sliding door mechanism 1 are arranged at the top end of the door 2 of the box. The active sliding door mechanism 1 and the first driven sliding door mechanism 9 are connected to the door panel 3 through the first hanging bracket 56. The door body assembly further includes: a second driven sliding door mechanism 18, and the second driven sliding door mechanism 18 is arranged at the bottom end of the door 2 of the box. The second driven sliding door mechanism 18 is connected to the door panel 3 through the second hanging bracket 57. During the opening or closing process of the door 2 of the box, the second driven sliding door mechanism 18 cooperates to guide the door panel 3 to move relative to the width direction of the door 2 of the box.

[0090] Specifically, during the opening or closing process of the door 2 of the box, the box body 4 drives the door panel 3 through the active sliding door mechanism 1. At the same time, the active sliding door mechanism 1 drives the door panel through the first driven sliding door mechanism 9, so as to drive the door panel 3 to move relative to the width direction of the door 2 of the box through the active sliding door mechanism 1 and the first driven sliding door mechanism 9, thereby avoiding interference between the door panel 3 and the obstacles outside. During this process, the second driven sliding door mechanism 18 cooperates to guide the door panel 3 to move relative to the width direction of the door 2 of the box, which can effectively improve the stability during movement.

[0091] 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. The door panel 3 will move along a predetermined trajectory during the sliding process, avoiding the shaking and instability phenomena caused by the direction deviation. This restrictive effect ensures the stability of the door panel 3.

[0092] As Figure 1 and Figure 2 shown, a first end cover 21 is provided at the top end of the door 2 of the box. An installation groove for placing 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 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 end of the door 2 of the box. An installation groove for placing 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.

[0093] In an embodiment, as Figure 6 and Figure 7 shown, the second driven sliding door mechanism 18 includes: a third base 181 and a fourth slider 182. The third base 181 is connected to the door 2 of the box, and the third base 181 is formed with a fourth guide rail 1811. The fourth slider 182 is slidably arranged on the fourth guide rail 1811 and is connected to the door panel 3 through the support plate 53 of the corresponding hanging bracket 5.

[0094] In this embodiment, a fourth guide rail 1811 is provided inside the third base 181, and the fourth slider 182 is connected to the door panel 3 through the hanging bracket 5. When the door panel 3 moves relative to the cabinet door 2, the fourth slider 182 moves on the fourth guide rail 1811, so as to cooperate with guiding the movement of the door panel 3 and the cabinet door 2. The structure of the hanging bracket 5 in this embodiment is similar to the structure connected to the active sliding door mechanism 1 and the first driven sliding door mechanism 9 described above, and will not be elaborated here.

[0095] 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.

[0096] 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.

[0097] 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 high; while plane contact has a simple structure, but may require more frequent lubrication and maintenance. Therefore, when selecting, factors such as service conditions, cost - effectiveness, and maintenance convenience should be comprehensively considered.

[0098] In another embodiment of the present application, as Figures 1 to 9 shown, a refrigeration device is provided, including: a box body 4 and a door body assembly as provided in any of the above - mentioned embodiments. Among them, the box body 4 forms a storage space, and the cabinet 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 - mentioned embodiments and will not be elaborated here.

[0099] By providing the door panel 3 on the cabinet door 2, when the refrigeration device is an embedded type and is arranged in a groove - shaped space or between two cabinets, the door panel 3 can be set flush with the side wall of the groove or the cabinets on both sides, so as to reduce the gap between the refrigeration device and the adjacent wall or cabinet, making it more beautiful.

[0100] Meanwhile, when the door 2 rotates, the active sliding door mechanism 1 can drive the door panel 3 to move relative to the door 2 during the rotation of the door 2 to move as far away as possible from the walls of the side door of the cabinet 4 or obstacles such as the cabinet body, so as to prevent these obstacles from blocking the door panel 3 and affecting the rotation of the door 2, resulting in the door 2 being unable to be opened or closed normally.

[0101] The combination of the door 2 and the door panel 3 enables the refrigeration equipment to avoid interference between the door panel 3 and surrounding objects when opening and closing, greatly improving the convenience of use. 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.

[0102] It can be understood that if the door body assembly has the beneficial effects of the above embodiments, the refrigeration equipment correspondingly has the beneficial effects of the above embodiments, and its specific implementation manners can refer to the above embodiments, which will not be elaborated in this application.

[0103] In some embodiments, as Figure 8 and Figure 9 shown, the door body assembly and the cabinet 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 cabinet 4 to be integrally embedded in the cabinet. During the process of the 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 door 2 in a direction away from or close to the hinge, so that the door panel 3 can avoid the side walls of the first cabinet body 6 and the second cabinet body 7.

[0104] During the process of the 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 door 2 in a direction away from or close to the hinge. 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 without colliding or jamming with the side walls of the cabinet through the movement of the preset distance.

[0105] For example, as Figure 8 and Figure 9 shown, during the opening process of the door 2, the active sliding door mechanism 1 drives the door panel 3 to move a preset distance along the door 2 in a direction away from the hinge. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet body 7, enabling the door 2 to be fully opened, facilitating users to access items.

[0106] Similarly, during the closing process of the cabinet door 2, the active sliding door mechanism 1 drives the door panel 3 to move a preset distance along the cabinet door 2 towards the hinge. In this way, the door panel 3 can smoothly avoid the side wall of the first cabinet body 6, enabling the cabinet door 2 to be completely closed, maintaining the overall aesthetics and sealing performance.

[0107] In some embodiments, as Figures 1 to 2 shown, the cabinet 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 cabinet door 2, the door panel 3 can be driven to move relative to the corresponding cabinet door 2.

[0108] In this application, the cabinet 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 cabinet 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 the user to store or take out the items in the storage space. The door panel 3 of each door body assembly can also slide relative to the corresponding cabinet door 2. When the cabinet door 2 is closed, the door panel 3 can be flush with the side cabinet body, or when the cabinet door 2 is opened, the door panel 3 can avoid the obstacles on both sides.

[0109] Specifically, the cabinet 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 cabinet door 2 of the first door body assembly is rotatably connected to the cabinet body 4 to open or close the first storage space, and the cabinet door 2 of the second door body assembly is rotatably connected to the cabinet body 4 to open or close the second storage space.

[0110] Furthermore, the first door body assembly and the second door body assembly are arranged up and down along the height direction of the cabinet door 2. The first door body assembly is provided with an active sliding door mechanism 1, a first driven sliding door mechanism 9, a second driven sliding door mechanism 18, and a corresponding hanging bracket 5. The corresponding active sliding door mechanism 1, first driven sliding door mechanism 9, and second driven sliding door mechanism 18 can be used to control the corresponding movement of the door panel 3 and the cabinet door 2. The second door body assembly is provided with an active sliding door mechanism 1, a first driven sliding door mechanism 9, a second driven sliding door mechanism 18, and a corresponding hanging bracket 5. The corresponding active sliding door mechanism 1, first driven sliding door mechanism 9, and second driven sliding door mechanism 18 can be used to control the corresponding movement of the door panel 3 and the cabinet door 2.

[0111] 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 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 all be covered within the scope of the claims of the present invention.
