[0066] The following Figures 1 to 12 , through specific embodiments and their application scenarios, will elaborate in detail on the sliding door mechanism, door body assembly, and refrigeration equipment provided by the embodiments of the present utility model.

[0067] In the first aspect, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the embodiments of the present utility model provide a sliding door mechanism, which is applied to a refrigeration equipment. The refrigeration equipment includes a box body 6 and a box door 1. The box door 1 is rotatably arranged on the box body 6 through a hinge 7. The sliding door mechanism includes: a linkage member 3 and a transmission assembly 4.

[0068] The first end of the linkage member 3 is configured to be rotatably disposed on the cabinet body 6 and capable of moving along the width direction of the cabinet body 6, and the second end of the linkage member 3 is configured to be rotatably disposed on the cabinet door 1.

[0069] The transmission assembly 4 is configured to be disposed between the second end of the linkage member 3 and the cabinet door 2.

[0070] During the process of the cabinet door 1 opening or closing the cabinet body 6, the second end of the linkage member 3 rotates relative to the cabinet door 1, thereby driving the transmission assembly 4 to drive the cabinet door 2 to move along the width direction of the cabinet door 1;

[0071] Wherein, when the cabinet door 1 closes the cabinet body 6, the first end of the linkage member 3 is far from the hinge 7; when the cabinet door 1 opens the cabinet body 6, the first end of the linkage member 3 approaches the hinge 7.

[0072] It can be understood that as Figure 9 shown, the cabinet body 6 is provided with a hinge 7, and a hinge shaft 71 is arranged on the hinge 7. The cabinet door 1 is rotatably arranged on the hinge shaft 71 to realize the opening or closing of the cabinet door 1 relative to the cabinet body 6.

[0073] In this embodiment, the first end of the linkage member 3 is rotatably disposed on the cabinet body 6. When the cabinet door 1 rotates relative to the cabinet body 6, the second end of the linkage member 3 rotates in a circular motion with the hinge shaft 71 as the center, thereby driving the first end of the linkage member 3 to move along the width direction of the cabinet body 6. The position of the second end of the linkage member 3 on the cabinet door 1 is fixedly arranged, and thus the second end of the linkage member 3 is driven to rotate relative to the cabinet door 1.

[0074] The transmission assembly 4 is used to convert the rotational motion of the linkage member 3 into a linear motion and drive the linear movement of the cabinet door 2 relative to the cabinet door 1.

[0075] Optionally, the transmission assembly 4 can be a crank-slider mechanism or a lead screw mechanism.

[0076] In practical applications, during the opening process of the box door 1, the box door 1 drives the second end of the linkage 3 to rotate relative to the hinge axis 71. The first end of the linkage 3 moves in the width direction of the box body 6 towards the hinge 7, driving the second end of the linkage 3 to rotate clockwise relative to the box door 1. Then, it controls the transmission assembly 4 to drive the cabinet door 2 to move in the width direction of the box door 1 away from the hinge 7, that is, move towards the left relative to the box door 1. In this way, it can avoid interference between the cabinet door 2 and the cabinet body around the refrigeration equipment. During the closing process of the box door 1, the box door 1 drives the second end of the linkage 3 to rotate relative to the hinge axis 71. The first end of the linkage 3 moves in the width direction of the box body 6 away from the hinge 7, driving the second end of the linkage 3 to rotate counterclockwise relative to the box door 1. Then, it controls the transmission assembly 4 to drive the cabinet door 2 to move in the width direction of the box door 1 towards the hinge 7, that is, move towards the right relative to the box door 1. In this way, it can ensure that the cabinet door 2 can avoid the cabinet body around the refrigeration equipment when the box door 1 is closed and reset the cabinet door 2.

[0077] For the sliding door mechanism shown in this embodiment, by rotatably arranging the first end of the linkage 3 on the box body 6, and the first end of the linkage 3 can move in the width direction of the box body 6. The second end of the linkage 3 is rotatably arranged on the box door 1, and a transmission assembly 4 is arranged between the second end of the linkage 3 and the cabinet door 2. When the box door 1 is opened, the box door 1 drives the second end of the linkage 3 to rotate relative to the box door 1, controlling the transmission assembly 4 to drive the cabinet door 2 to move in the width direction of the box door 1 away from the hinge 7, so that the cabinet door 2 can avoid interference with the cabinet body on the side. When the box door 1 is closed, it drives the second end of the linkage 3 to rotate relative to the box door 1, controlling the transmission assembly 4 to drive the cabinet door 2 to move in the width direction of the box door 1 towards the hinge 7, so that the cabinet door 2 can return to its original position, ensuring that the cabinet door 2 does not interfere with the cabinet door of the cabinet body on the side.

[0078] In some embodiments, as Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, the linkage 3 includes: a hinge joint 31 and a connecting rod 32.

[0079] The hinge joint 31 is configured to be rotatably arranged in the strip-shaped groove 61 on the box body 6 and can slide along the extension direction of the strip-shaped groove 61. The strip-shaped groove 61 extends in the width direction.

[0080] The first end of the connecting rod 32 is connected to the hinge joint 31, and the second end of the connecting rod 32 is configured to be rotatably arranged on the box door 1 and connected to the transmission assembly 4.

[0081] It is understandable that the strip-shaped groove 61 extends along the width direction of the cabinet door 1. Based on the sliding of the hinge joint 31 in the strip-shaped groove 61, the hinge joint 31 can slide along the width direction of the cabinet door 1. Since the position of the second end of the connecting rod 32 relative to the cabinet door 1 is fixedly arranged, the hinge joint 31 then drives the second end of the connecting rod 32 to rotate relative to the cabinet door 1, and drives the transmission assembly 4 to drive the cabinet door 2 to move along the width direction of the cabinet door 1.

[0082] In practical applications, during the opening process of the cabinet door 1, the cabinet door 1 drives the second end of the connecting rod 32 to rotate relative to the hinge shaft 71. The first end of the connecting rod 32 pulls the hinge joint 31 to slide along the width direction of the cabinet door 1 in the strip-shaped groove 61 towards the direction close to the hinge 7, and then drives the second end of the connecting rod 32 to rotate clockwise relative to the cabinet door 1. Then, it controls the transmission assembly 4 to drive the cabinet door 2 to move along the width direction of the cabinet door 1 towards the direction away from the hinge 7, that is, to move towards the left side relative to the cabinet door 1. In this way, it can avoid interference between the cabinet door 2 and the cabinet doors on the side cabinets; during the closing process of the cabinet door 1, the cabinet door 1 drives the second end of the connecting rod 32 to rotate relative to the hinge shaft 71. The first end of the connecting rod 32 pulls the hinge joint 31 to slide along the width direction of the cabinet door 1 in the strip-shaped groove 61 towards the direction away from the hinge 7, and then drives the second end of the connecting rod 32 to rotate counterclockwise relative to the cabinet door 1. Then, it controls the transmission assembly 4 to drive the cabinet door 2 to move along the width direction of the cabinet door 1 towards the direction close to the hinge 7, that is, to move towards the right side relative to the cabinet door 1. In this way, it can ensure that the cabinet door 2 can avoid the cabinet doors on the side cabinets when closing the cabinet door 1 and reset the cabinet door 2.

[0083] In this embodiment, by providing the hinge joint 31 and the connecting rod 32 on the linkage member 3, a compact design in a relatively small space can be achieved, and the structure is simple and easy to repair.

[0084] In some embodiments, such as Figure 5 、 Figure 6 and Figure 8 shown, the transmission assembly 4 includes: a gear 41 and a rack 42.

[0085] The gear 41 is connected to the second end of the linkage member 3 and can rotate relative to the cabinet door 1 under the drive of the linkage member 3.

[0086] The rack 42 is meshed with the gear 41. The rack 42 extends along the width direction and is configured to be connected to the cabinet door 2.

[0087] It is understandable that the gear 41 of this embodiment is provided at the second end of the linkage member 3, and the gear 41 is meshed with the rack 42.

[0088] When the cabinet door 1 is opened, the cabinet door 1 drives the second end of the linkage 3 to rotate relative to the hinge axis 71. The first end of the linkage 3 moves in the width direction of the cabinet body 6 towards the hinge 7, driving the second end of the linkage 3 to rotate clockwise relative to the cabinet door 1. Based on the unchanged installation position of the gear 41 on the cabinet door 1, the gear 41 is then driven to rotate clockwise. The rotation of the gear 41 drives the rack 42 to move in the width direction of the cabinet door 1 away from the hinge 7, and the rack 42 drives the cabinet door 1 to move away from the hinge 7, thus avoiding interference between the cabinet door 2 and the cabinet doors of the side cabinets; during the closing process of the cabinet door 1, the cabinet door 1 drives the second end of the linkage 3 to rotate relative to the hinge axis 71. The first end of the linkage 3 moves in the width direction of the cabinet body 6 away from the hinge 7, driving the second end of the linkage 3 to rotate counterclockwise relative to the cabinet door 1. Based on the unchanged installation position of the gear 41 on the cabinet door 1, the gear 41 is then driven to rotate counterclockwise. The rotation of the gear 41 drives the rack 42 to move in the width direction of the cabinet door 1 towards the hinge 7, and the rack 42 drives the cabinet door 1 to move towards the hinge 7, thus ensuring that the cabinet door 2 can avoid the cabinet doors of the side cabinets when the cabinet door 1 is closed and resetting the cabinet door 2.

[0089] In this embodiment, by setting the transmission assembly 4 as the gear 41 and the rack 42, the structure is simple, easy to install and maintain, and can achieve a relatively high transmission efficiency.

[0090] In some embodiments, as Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 shown, the sliding door mechanism further includes a sliding module 5.

[0091] The sliding module 5 is configured to be disposed between the cabinet door 1 and the cabinet door 2, and the sliding module 5 is used to guide the cabinet door 2 to move relative to the cabinet door 1 in the width direction.

[0092] It can be understood that due to the self - weight of the cabinet door 2, during the process of the cabinet door 2 moving relative to the cabinet door 1, the cabinet door 2 may vibrate or tilt. The sliding module 5 can provide stable support and guiding functions, guiding the reliable and stable movement of the cabinet door 2 relative to the cabinet door 1.

[0093] The sliding module 5 includes a first sliding member and a second sliding member. The first sliding member and the second sliding member are slidably engaged in the width direction. The first sliding member can be installed on the cabinet door 1 and the second sliding member can be installed on the cabinet door 2, or the first sliding member can be installed on the cabinet door 2 and the second sliding member can be installed on the cabinet door 1. The sliding module 5 realizes the relative movement between the cabinet door 1 and the cabinet door 2 through the relative sliding of the first sliding member and the second sliding member.

[0094] In some embodiments, as Figure 8 andFigure 9 As shown, the sliding module 5 includes a slide rail 51 and a moving member.

[0095] The slide rail 51 is configured to be provided on the door 1 and extend along the width direction.

[0096] The moving member is movably provided on the slide rail 51 along the width direction, and the moving member is configured to be detachably connected to the cabinet door 2.

[0097] It can be understood that the slide rail 51 can be in the structural form of a chute, and the moving member is correspondingly in the structural form of sliding along the chute; the slide rail 51 can also be in the structural form of a slide bar; the moving member is correspondingly in the structural form of wrapping the slide rail and moving.

[0098] The moving member can move along the extending direction of the slide rail 51. Based on the guiding and supporting effects of the slide rail 51, the moving member can move stably and reliably along the slide rail 51. Moreover, based on the high rigidity of the slide rail 51, a high straightness can be provided for the moving member, so that the cabinet door 2 can move stably and reliably along the width direction of the door 1.

[0099] At the same time, the detachable connection between the moving member and the cabinet door 2 facilitates the installation of the cabinet door 2. The detachable connection method improves the versatility and adaptability of the sliding door mechanism, simplifies the manufacturing and assembly processes, and reduces the production cost.

[0100] Optionally, the detachable connection between the moving member and the cabinet door 2 can be achieved by fasteners, or by snap connection, or by magnetic connection.

[0101] In some embodiments, as Figure 5 and Figure 7 shown, at least two sets of sliding modules 5 are provided. One end of the transmission component 4 is connected to the second end of the linkage member 3, and the other end is connected to the moving member of one of the at least two sets of sliding modules 5.

[0102] Wherein, the transmission component 4 is used to drive the moving member to move along the slide rail 51 under the drive of the linkage member 3.

[0103] It is understandable that multiple sets of sliding modules 5 can be provided. One set of the sliding modules 5 is used to connect with the transmission component 4, so that the linkage 3 can control the transmission component 4 to drive the moving part to move along the slide rail 51. Further, the linkage 3 can control the transmission component 4 to drive the cabinet door 2 to move relative to the box door 1 along the extension direction of the slide rail 51. The sliding module 5 connected to the transmission component 4 serves as an active driving mechanism, realizing the cooperative design of the linkage 3 and the sliding module 5. For cooperative guiding, the slide rails 51 in each sliding module 5 are arranged in parallel, ensuring that the cabinet door 2 can be accurately guided during movement, avoiding interference with the side wall of the cabinet body. Moreover, the remaining multiple sets of sliding modules 5 serve as passive guiding mechanisms. Through the cooperation of the multiple sets of sliding modules 5, the cabinet door 2 can move smoothly and stably relative to the box door 1, improving the convenience and reliability of use, and being conducive to realizing the precise control and smooth movement of the cabinet door 2.

[0104] Specifically, four sets of sliding modules 5 are provided in this embodiment. Two sets of the sliding modules 5 are arranged along the width direction and are located between the upper end of the box door 1 and the upper end of the cabinet door 2. The other two sets of sliding modules 5 are arranged along the width direction and are located between the lower end of the box door 1 and the lower end of the cabinet door 2. And, one set of the two sets of sliding modules 5 located at the upper end and close to the hinge 7 is connected to the transmission component 4. The remaining three sets of sliding modules 5 are respectively arranged at the remaining triangles of the box door 1. The slide rails 51 among the four sets of sliding modules 5 are arranged in parallel.

[0105] Correspondingly, among the three sets of passive sliding modules 5, the sliding module 5 located at the upper end of the box door 1 has the same structure as the sliding module 5 located at the lower end of the box door 1 and is symmetrically arranged on the box door 1.

[0106] In some embodiments, as Figure 8 and Figure 9 shown, the moving part includes a sliding part 52 and a hanging part 53; the sliding part 52 is movably arranged along the width direction on the slide rail 51, and the hanging part 53 is configured to be connected to the cabinet door 2 and is hung on the sliding part 52.

[0107] It is understandable that the hanging part 53 is used to connect the sliding part 52 and the cabinet door 2 to realize the movement of the cabinet door 2 relative to the box door 1 driven by the sliding part 52. Moreover, the hanging part 53 is configured to be detachably connected to the cabinet door 2.

[0108] Further, the sliding member 52 of this embodiment includes a sliding body 521 and an adapter base 522. The sliding body 521 and the adapter base 522 are fixedly connected. A support frame 511 is provided on the slide rail 51. A round hole is provided on the support frame 511, and a ball is installed in the round hole. The sliding body 521 is in rolling contact with the slide rail 51 to move on the slide rail 51 in the width direction. A first card slot 5221 is provided on the adapter base 522 for hanging the hanging member 53 on the sliding body 521. The relative movement between the sliding body 521 and the slide rail 51 in this embodiment is rolling friction, so as to reduce the frictional force and improve the moving efficiency of the moving member. This design can accurately control the movement trajectory and distance of the cabinet door 2, avoid interference with the side wall of the cabinet body, and realize the smooth opening and closing of the box door 1.

[0109] Optionally, as Figure 8 shown, the sliding module 5 is an active driving mechanism. The sliding module 5 is connected to the transmission component 4. In this embodiment, a rack 42 is fixedly connected to the sliding body 521. The rack 42 is meshed with a gear 41, and the connecting rod 32 is connected to the gear 41, so that the connecting rod 32 can control the transmission component 4 to drive the movement of the sliding body 521.

[0110] In some embodiments, as Figures 8 to 12 shown, the hanging member 53 includes a fixed seat 531 and a hanging part 532; the fixed seat 531 is configured to be connected to the cabinet door 2, and the hanging part 532 is adjustably arranged on the fixed seat 531 in the vertical direction or the horizontal direction, and the hanging part 532 is hung on the sliding member 52.

[0111] It can be understood that a slight adjustment in the vertical direction or the horizontal direction can be achieved between the hanging part 532 and the fixed seat 531. Thus, by adjusting the relative position between the hanging part 532 and the fixed seat 531, the position deviation between the cabinet door 2 and the box door 1 can be adjusted, so that the box door 1 and the cabinet door 2 can correct slight deviations in installation or manufacturing through fine adjustment, ensuring the aesthetic appearance of the installation of the box door 1 and the cabinet door 2.

[0112] Specifically, the fixed seat 531 is connected to the cabinet door 2 to provide additional structural support for the cabinet door 2. An installation groove is formed on the fixed seat 531 for accommodating the hanging part 532; the hanging part 532 is slidably arranged in the installation groove, and a first card joint 5321 is formed on the hanging part 532 to adjust the relative position between the cabinet door 2 and the box door 1 by adjusting the position of the hanging part 532 in the installation groove. Through the adjustable design, the user can adjust the position of the cabinet door 2 according to actual needs to meet the requirements of different usage scenarios.

[0113] Specifically, the first card connector 5321 is a U-shaped hook facing downward, which can pass through the notch and slide into the first card slot 5221. The hanging member 532 is provided with a first rectangular hole extending in the up and down direction. The fixing base 531 is provided with two mounting holes and a mounting groove extending left and right between the two mounting holes. The side wall of the mounting groove is provided with a second rectangular hole extending in the left and right direction. The hanging member 532 can slide in the mounting groove. By controlling the position of the hanging member 532 in the mounting groove, the hanging member 532 can move up and down relative to the fixing base 531. Screws can be arranged to pass through the first rectangular hole on the mounting groove and the second rectangular hole on the hanging member 532, so as to form a hanging member 532 that can be adjusted in both the up and down and left and right directions. And through the relative positions of the mounting holes of the fixing base 531 and the cabinet door 2, the positions of the fixing base 531 and the cabinet door 2 can be adjusted in the up, down, left, and right directions.

[0114] As Figure 11 and Figure 12 shown, the process of installing the hanging member 53 on the cabinet door 2 is as follows:

[0115] Thread the hanging member 532 through the mounting groove of the fixing base 531. Use screws to pass through the second rectangular hole, the first rectangular hole, and the cabinet door 2 to integrally connect the fixing base 531 to the cabinet door 2. Hang the first card connector 5321 on the hanging member 532 that has been connected in the first card slot 5221 to complete the connection between the hanging member 532 and the adapter 522. Then, by observing the positional relationship between the cabinet door 2 and the box door 1, check whether there is a deviation. If there is a deviation, the position can be adjusted through the first rectangular hole and the second rectangular hole. When the deviation is large, the screws can be removed to separate the hanging member 53 from the cabinet door 2 and adjust the position of the hanging member 53. For the cabinet door 2 and the fixing base 531 and the hanging member 532 assembly, adjust the position of the hanging member 532. If the positional relationship meets the requirements and no adjustment is needed, then use screws to pass through the mounting holes on both sides of the fixing base 531 and the cabinet door 2 to further fix the cabinet door 2 and the fixing base 531 to keep its position stable. Through the above method, not only can the position of the fixing base 531 be finely adjusted, but also it can be ensured that all fixings are firm, guaranteeing the accurate positional relationship between the cabinet door 2 and the box door 1.

[0116] In the second aspect, as Figure 2 shown, the embodiment of the present invention further provides a door assembly, including: a box door 1, a cabinet door 2, and a sliding door mechanism. The box door 1 is configured to be rotatably arranged on the box body 6 to open or close the storage compartment in the box body 6. The cabinet door 2 is movably arranged on the box door 1 along the width direction of the box door 1. The sliding door mechanism is the sliding door mechanism as described above.

[0117] Among them, the thickness of the cabinet door 1 is 18 - 60 mm. For example, the thickness of the cabinet door 1 can be 18 mm, 25 mm, 35 mm, 50 mm, 55 mm or 60 mm; the thickness of the cabinet door 2 is 12 - 26 mm. For example, the thickness of the cabinet door 2 can be 12 mm, 15 mm, 20 mm or 26 mm; the cabinet door 2 can be a wooden door panel or a plastic door panel.

[0118] Specifically, since the door body assembly includes a sliding door mechanism, and the specific structure of the sliding door mechanism refers to the above embodiment, the door body assembly shown in this embodiment includes all the technical solutions of the above embodiment. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above embodiment, which will not be elaborated here one by one.

[0119] It can be understood that the door body assembly in the present utility model can be applied to household appliances, such as a refrigerator. During the opening or closing process of the cabinet door 1, the sliding door mechanism drives the cabinet door 2 to move relative to the cabinet door 1.

[0120] For the door body assembly shown in this embodiment, by rotatably connecting the cabinet door 1 to the cabinet body 6, movably arranging the cabinet door 2 on the outside of the cabinet door 1 along the width direction of the cabinet door 1, and connecting the cabinet door 1 and the cabinet door 2 by using the sliding door mechanism, during the opening or closing process of the sliding door mechanism, controlling the cabinet door 2 to move relative to the cabinet door 1, so that the cabinet door 1 can avoid the side cabinet body during the opening and closing process, thereby avoiding the interference between the cabinet door 2 and the outside when the cabinet door 1 rotates, and meeting the use requirements of users in different scenarios.

[0121] Specifically, during the movement of the cabinet door 2 relative to the cabinet door 1, the cabinet door 2 can move left and right relative to the cabinet door 1 along the width direction.

[0122] Such a design not only improves the convenience of use, but also can avoid possible damage to the door body assembly during use. At the same time, this design also enables the refrigeration equipment to better integrate into the home environment, achieving the effects of overall beauty and sealing.

[0123] In some embodiments, as Figure 2 、 Figure 3 and Figure 4 shown, the door body assembly and the cabinet body 6 are configured to be arranged in the accommodation space between the first cabinet body 8 and the second cabinet body 9.

[0124] During the opening or closing process of the cabinet door 1, the transmission assembly 4 is used to change the position of the cabinet door 2 on the cabinet door 1, so that the cabinet door 2 can avoid the side wall of the first cabinet body 8 or the second cabinet body 9.

[0125] It is understandable that an opening is provided on the outer side of the accommodation space between the first cabinet body 8 and the second cabinet body 9. This design enables the door assembly and the box body 6 to be integrally embedded in the cabinet body. During the process of the box door 1 passing through the opening to control the opening or closing of the accommodation space, the sliding door mechanism is configured to drive the cabinet door 2 on the box door 1 to move a preset distance in a direction away from or towards the box body 6, so that the cabinet door 2 avoids the side walls of the first cabinet body 8 and the second cabinet body 9.

[0126] During the process of the box door 1 passing through the opening to control the opening or closing of the accommodation space, the sliding door mechanism is configured to drive the cabinet door 2 on the box door 1 to move in a direction away from or towards the box body 6, and can also control the cabinet door 2 to move a preset distance. This design is mainly to avoid interference between the cabinet door 2 and the side walls of the first cabinet body 8 and the second cabinet body 9. Through the movement of the preset distance, the box door 1 can be smoothly opened or closed without colliding or jamming with the side walls of the cabinet body.

[0127] For example, during the opening process of the box door 1, the sliding door mechanism drives the cabinet door 2 to move a preset distance along the box door 1 in a direction away from the hinge 7. In this way, the cabinet door 2 can smoothly avoid the side wall of the second cabinet body 9, enabling the box door 1 to be fully opened, facilitating users to access items.

[0128] Similarly, during the closing process of the box door 1, the sliding door mechanism drives the cabinet door 2 to move a preset distance along the box door 1 in a direction towards the hinge 7. In this way, the cabinet door 2 can smoothly avoid the side wall of the first cabinet body 8, enabling the box door 1 to be fully closed, maintaining the overall aesthetics and sealing performance.

[0129] In some embodiments, as Figure 3 and Figure 4 shown, the box door 1 is rotatably connected to the box body 6 through the hinge 7; the cabinet door 2 can move between a first position and a second position relative to the box door 1 in the width direction.

[0130] When the cabinet door 2 is in the first position, the box door 1 closes the storage compartment, and the side of the cabinet door 2 facing the hinge 7 is arranged close to the hinge 7.

[0131] When the cabinet door 2 is in the second position, the box door 1 opens the storage compartment, and the side of the cabinet door 2 facing the hinge 7 is arranged away from the hinge 7 to avoid the side wall of the first cabinet body 8 or the second cabinet body 9.

[0132] It is understandable that the storage compartment is used to store items to be refrigerated or frozen. When the box door 1 closes the storage compartment, the box door 1 is in the closed state, and the side of the cabinet door 2 is at a first distance (close to zero) relative to the hinge 7 of the refrigeration device. For example, the side of the cabinet door 2 and the side of the box door 1 are flush. At this time, the cabinet door 2 can completely cover the box door 1, ensuring that the door body of the refrigeration device exposed in the accommodation space is consistent with the surrounding first cabinet body 8 and second cabinet body 9 in appearance.

[0133] When the door 1 of the box is opened to access the storage compartment, the door 1 of the box is in an open state. The side of the cabinet door 2 is at a second distance (the second distance is greater than the first distance) relative to the hinge 7 of the refrigeration device. For example, the side wall of the cabinet door 2 and the side wall of the door 1 of the box are misaligned, and a gap is formed that can accommodate the side of the first cabinet body 8 or the second cabinet body 9, so as to prevent the cabinet door 2 from colliding with or interfering with the first cabinet body 8 or the second cabinet body 9 due to the opening of the door 1 of the box.

[0134] In some embodiments, as Figure 5 and Figure 6 shown, the door assembly is provided with the sliding door mechanism as described above. The door 1 of the box is provided with a groove 11, and the sliding module 5 is arranged in the groove 11.

[0135] The door assembly further includes a decorative member; the decorative member is used to cover the notch end of the groove 11.

[0136] It can be understood that the sliding module 5 is arranged in the groove 11, which can enable the door 1 of the box to form a stable cooperation with the sliding module 5 during the opening and closing processes of the door 1 of the box, reduce the overall thickness of the door 1 of the box and the cabinet door 2, and furthermore, the sliding module 5 is hidden in the groove 11. When the cabinet door 2 moves relative to the door 1 of the box, the user can only observe the movement of the cabinet door 2 relative to the door 1 of the box and cannot see the sliding of the sliding module 5, enhancing the aesthetics and consistency of the movement process of the cabinet door 2.

[0137] In this embodiment, four grooves 11 are provided. The four grooves 11 are respectively arranged at the four corners of the door 1 of the box. A plurality of threaded holes are provided in the grooves 11, and through holes corresponding to the threaded holes in the grooves 11 are provided on the slide rail 51. In this way, the slide rail 51 can be fixed in the groove 11 by setting bolts on the slide rail 51.

[0138] When the refrigeration device is installed in a fully embedded manner, it is necessary to provide the cabinet door 2 on the outside of the door 1 of the box. The sliding module 5 is arranged in the groove 11 on the door 1 of the box, which can ensure the aesthetics of the cabinet door 2 when the door 1 of the box and the cabinet door 2 move relative to each other.

[0139] When the refrigeration device is installed in a flush-mounted manner, the cabinet door 2 does not need to be installed on the outside of the door 1 of the box. In order to ensure the aesthetics of the outside of the door 1 of the box, the decorative member is covered on the groove 11 to ensure the aesthetics of the appearance of the refrigeration device.

[0140] Specifically, the decorative member can be a decorative cover with the same material and color as the door 1 of the box.

[0141] The user can choose whether to install the cabinet door 2 according to actual needs and select a suitable connection method according to different application scenarios.

[0142] In a third aspect, as Figure 2 、 Figure 3 andFigure 4 As shown in the figure, an embodiment of the present utility model further provides a refrigeration device, including: a box body 6 and a door body assembly.

[0143] The box body 6 and the door body assembly as above, the box body 6 has a storage compartment, and the box door 1 is rotatably arranged on the box body 6 to open or close the storage compartment. The box body 6 and the door body assembly as above, the box body 6 has a storage compartment, and the box door 1 is rotatably arranged on the box body 6 to open or close the storage compartment.

[0144] Specifically, since the refrigeration device includes a door body assembly, and the specific structure of the door body assembly refers to the above embodiment, the refrigeration device shown in this embodiment includes all the technical solutions of the above embodiment. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above embodiment, which will not be elaborated here one by one.

[0145] It can be understood that during the opening process of the box door 1, the sliding door mechanism drives the cabinet door 2 to move away from the hinge 7, which can avoid interference between the cabinet door 2 and the cabinet doors on the side. During the closing process of the box door 1, the sliding door mechanism drives the cabinet door 2 to move towards the hinge 7 to ensure that the cabinet door 2 can avoid the cabinet doors on the side when closed.

[0146] The combination of the box door 1 and the cabinet door 2 enables the refrigeration device to avoid interference between the cabinet door 2 and the cabinet doors of the surrounding cabinets when opening and closing, greatly improving the use convenience. Especially in a restricted kitchen environment, this design advantage is more obvious. In addition, the setting of the sliding door mechanism enables the cabinet door 2 to move smoothly during the opening and closing processes, improving the service life and stability of the refrigerator.

[0147] The refrigeration device in this application is applied as a refrigerator for example, but it should be understood that the refrigeration device of this application can also be applied as a freezer or any other suitable device, which is not limited here.

[0148] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model, rather than to limit 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 replacements 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.
