[0065] The following Figures 1 to 12 , through specific embodiments and their application scenarios, the sliding door mechanism, door body assembly and refrigeration equipment provided by the embodiments of the present utility model are described in detail.

[0066] In a 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, and includes: a driving assembly 3 and a transmission assembly 4.

[0067] The first end of the driving assembly 3 is configured to be rotatably arranged on the box body 6, the second end of the driving assembly 3 is configured to be rotatably arranged on the door 1 of the refrigeration equipment, and the first end of the driving assembly 3 is arranged in a dislocation manner with respect to the hinge shaft 71 between the box body 6 and the door 1.

[0068] The transmission assembly 4 is configured to be disposed between the second end of the drive assembly 3 and the cabinet door 2;

[0069] During the process of the box door 1 opening or closing the box body 6, the second end of the drive assembly 3 rotates relative to the box door 1, thereby driving the transmission assembly 4 to drive the cabinet door 2 to move along the width direction of the box door 1.

[0070] It can be understood that, as Figure 9 shown, the box body 6 is provided with a hinge 7, and a hinge shaft 71 is provided on the hinge 7. The box door 1 is rotatably arranged on the hinge shaft 71 to realize the opening or closing of the box door 1 relative to the box body 6.

[0071] In this embodiment, the first end of the drive assembly 3 is rotatably arranged on the hinge 7. When the box door 1 rotates relative to the box body 6 around the hinge shaft 71, the second end of the drive assembly 3 rotates in a circular motion with the hinge shaft 71 as the center. Since the first end of the drive assembly 3 and the hinge shaft 71 are arranged in a dislocation manner, the distance between the first end and the second end of the drive assembly 3 will change. And the position of the second end of the drive assembly 3 on the box door 1 is fixedly set, thereby driving the second end of the drive assembly 3 to rotate relative to the box door 1.

[0072] Optionally, the drive assembly 3 can be a crank mechanism or a gear assembly.

[0073] The transmission assembly 4 is used to convert the rotational motion of the drive assembly 3 into a linear motion and drive the linear movement of the cabinet door 2 relative to the box door 1.

[0074] Optionally, the transmission assembly 4 can be a crank-slider mechanism or a lead screw mechanism.

[0075] In practical applications, during the opening process of the cabinet door 1, the cabinet door 1 drives the second end of the driving component 3 to rotate relative to the hinge shaft 71. Based on the misaligned arrangement of the first end of the driving component 3 and the hinge shaft 71, the distance between the first end and the second end of the driving component 3 increases, driving the second end of the driving component 3 to rotate clockwise relative to the cabinet door 1. Then, it controls the transmission component 4 to drive the cabinet door 2 to move away from the hinge 7 along the width direction of the cabinet door 1, that is, move to the left relative to the cabinet 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 cabinet door 1, the cabinet door 1 drives the second end of the driving component 3 to rotate relative to the hinge shaft 71. Based on the misaligned arrangement of the first end of the driving component 3 and the hinge shaft 71, the distance between the first end and the second end of the driving component 3 decreases, driving the second end of the driving component 3 to rotate counterclockwise relative to the cabinet door 1. Then, it controls the transmission component 4 to drive the cabinet door 2 to move towards the hinge 7 along the width direction of the cabinet door 1, that is, move to the right relative to the cabinet door 1. In this way, it can ensure that the cabinet door 2 can avoid the cabinet body around the refrigeration equipment when the cabinet door 1 is closed and reset the cabinet door 2.

[0076] For the sliding door mechanism shown in this embodiment, by rotatably arranging the first end of the driving component 3 on the cabinet body 6, rotatably arranging the second end of the driving component 3 on the cabinet door 1, misaligning the first end of the driving component 3 with the hinge shaft 71 between the cabinet body 6 and the cabinet door 1, and arranging a transmission component 4 between the second end of the driving component 3 and the cabinet door 2. When the cabinet door 1 is opened, the cabinet door 1 drives the second end of the driving component 3 to rotate relative to the cabinet door 1, controlling the transmission component 4 to drive the cabinet door 2 to move away from the hinge 7 along the width direction of the cabinet door 1, so that the cabinet door 2 can avoid interference with the cabinet body on the side. When the cabinet door 1 is closed, it drives the second end of the driving component 3 to rotate relative to the cabinet door 1, controlling the transmission component 4 to drive the cabinet door 2 to move towards the hinge 7 along the width direction of the cabinet door 1, so that the cabinet door 2 can return to its original position, ensuring that the cabinet door 2 does not interfere with the cabinet body around the refrigeration equipment.

[0077] In some embodiments, such as Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, the driving component 3 includes: a first connecting rod 31 and a second connecting rod 32.

[0078] The first end of the first connecting rod 31 is rotatably arranged on the cabinet body 6 and is misaligned with the hinge shaft.

[0079] The first end of the second connecting rod 32 is rotatably connected to the second end of the first connecting rod 31; the second end of the second connecting rod 32 is rotatably arranged on the cabinet door 1 and is connected to the transmission component 4.

[0080] It is understandable that the first link 31 and the second link 32 are connected by a hinge, and the first link 31 and the second link 32 can rotate relative to each other. The first link 31 can rotate relative to the cabinet body 6, and the second link 32 can rotate relative to the cabinet door 1.

[0081] When the second end of the second link 32 makes a circular motion around the hinge axis 71 with the cabinet door 1 as the center, due to the misalignment of the first end of the first link 31 and the hinge axis 71, the distance between the second end of the second link 32 and the first end of the first link 31 changes, while the position of the second end of the second link 32 relative to the cabinet door 1 remains unchanged. As a result, the second end of the second link 32 rotates around the cabinet door 1, and drives the transmission component 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 second link 32 to rotate relative to the hinge axis 71. Based on the misalignment arrangement of the first end of the first link 31 and the hinge axis 71, the distance between the first end of the first link 31 and the second end of the second link 32 increases, driving the second end of the second link 32 to rotate clockwise relative to the cabinet door 1. Then, it controls the transmission component 4 to drive the cabinet door 2 to move along the width direction of the cabinet door 1 away from the hinge 7, that is, move to the left relative to the cabinet 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 cabinet door 1, the cabinet door 1 drives the second end of the second link 32 to rotate relative to the hinge axis 71. Based on the misalignment arrangement of the first end of the first link 31 and the hinge axis 71, the distance between the first end of the first link 31 and the second end of the second link 32 decreases, driving the second end of the second link 32 to rotate counterclockwise relative to the cabinet door 1. Then, it controls the transmission component 4 to drive the cabinet door 2 to move along the width direction of the cabinet door 1 towards the hinge 7, that is, move to the right relative to the cabinet door 1. In this way, it can ensure that the cabinet door 2 can avoid the cabinet body around the refrigeration equipment when closing the cabinet door 1 and reset the cabinet door 2.

[0083] In this embodiment, by providing the first link 31 and the second link 32 in the drive component 3, it can not only achieve a compact design in a small space, but also has a simple structure and is easy to repair.

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

[0085] The gear 41 is connected to the second end of the drive component 3 and can rotate under the drive of the drive component 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 driving assembly 3, and the gear 41 and the rack 42 are meshed.

[0088] When the box door 1 is opened, the box door 1 drives the second end of the driving assembly 3 to rotate relative to the hinge shaft 71. The distance between the first end and the second end of the driving assembly 3 increases, driving the second end of the driving assembly 3 to rotate clockwise relative to the box door 1. Based on the unchanged installation position of the gear 41 on the box door 1, the gear 41 is driven to rotate clockwise. The rotation of the gear 41 drives the rack 42 to move in the width direction of the box door 1 away from the hinge 7, and the rack 42 drives the box door 1 to move away from the hinge 7. In this way, interference between the cabinet door 2 and the cabinet body around the refrigeration equipment can be avoided; during the closing process of the box door 1, the box door 1 drives the second end of the driving assembly 3 to rotate relative to the hinge shaft 71. The distance between the first end and the second end of the driving assembly 3 decreases, driving the second end of the driving assembly 3 to rotate counterclockwise relative to the box door 1. Based on the unchanged installation position of the gear 41 on the box door 1, the gear 41 is driven to rotate counterclockwise. The rotation of the gear 41 drives the rack 42 to move in the width direction of the box door 1 towards the hinge 7, and the rack 42 drives the box door 1 to move towards the hinge 7. In this way, it can be ensured that the cabinet door 2 can avoid the cabinet body around the refrigeration equipment when the box door 1 is closed and the cabinet door 2 is reset.

[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 improve the 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 provided between the box 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 box door 1 in the width direction.

[0092] It is understandable that due to the self - weight of the cabinet door 2, during the movement of the cabinet door 2 relative to the box door 1, the cabinet door 2 may vibrate or tilt. The sliding module 5 can provide stable support and guiding functions to guide the reliable and stable movement of the cabinet door 2 relative to the box 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 of 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 and Figure 9 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 cabinet door 1 and extend in the width direction.

[0096] The moving member is movably provided on the slide rail 51 in 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 a structure that slides 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 a structure that wraps the slide rail and moves.

[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 cabinet 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 , Figure 6 and Figure 7 shown, there are at least two sets of sliding modules 5. One end of the transmission component 4 is connected to the second end of the driving component 3, and the other end is connected to the moving member of one of the at least two sets of sliding modules 5.

[0102] Among them, the transmission component 4 is used to drive the moving member to move along the slide rail 51 under the drive of the driving component 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 driving component 3 can control the transmission component 4 to drive the moving part to move along the slide rail 51. Furthermore, the driving component 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 with the transmission component 4 serves as an active driving mechanism, realizing the cooperative design of the driving component 3 and the sliding module 5. For cooperative guidance, the slide rails 51 in each sliding module 5 are arranged in parallel, ensuring that the cabinet door 2 can be accurately guided during the 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 smooth and stable movement of the cabinet door 2 relative to the box door 1 can be achieved, 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 with 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 with 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 with 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, and the first card slot 5221 is used to hang the hanging member 53 on the sliding body 521. The relative movement between the sliding body 521 and the slide rail 51 of this embodiment is rolling friction, so as to reduce the frictional force and improve the moving efficiency of the moving parts. This design can accurately control the movement track 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 second connecting rod 32 is connected to the gear 41, so that the second 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 small amount of 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 the slight deviation 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 vertical direction. The fixing base 531 is provided with two mounting holes and a mounting slot extending left and right between the two mounting holes. The side wall of the mounting slot is provided with a second rectangular hole extending in the left and right direction. The hanging member 532 can slide in the mounting slot. By controlling the position of the hanging member 532 in the mounting slot, the hanging member 532 can move up and down relative to the fixing base 531. A screw can be set to pass through the first rectangular hole on the mounting slot 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-down and left-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-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 slot 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 any 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 screw can be removed, the hanging member 53 is separated from the cabinet door 2, and the position of the hanging member 53 is adjusted. For the cabinet door 2 and the fixing base 531, the hanging member 532 assembly, the position of the hanging member 532 is adjusted. 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 cabinet of the refrigeration device 6 to open or close the storage compartment in the cabinet 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 embodiments, the door body assembly shown in this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above embodiments, which will not be elaborated herein 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 refrigerators. 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 outside the cabinet door 1 along the width direction of the cabinet door 1, and connecting the cabinet door 1 and the cabinet door 2 with a sliding door mechanism. During the opening or closing process of the sliding door mechanism, the movement of the cabinet door 2 relative to the cabinet door 1 is controlled, so that the cabinet door 1 can avoid the side cabinet body during the opening and closing processes, 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 component 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 away from or towards the box body 6, so that the cabinet door 2 can avoid 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 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 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 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 walls 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 box door 1 opens the storage compartment, the box door 1 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 box door 1 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 or interfering with the first cabinet body 8 or the second cabinet body 9 due to the opening of the box door 1.

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

[0135] The door body 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 box door 1 to form a stable cooperation with the sliding module 5 during the opening and closing processes of the box door 1, reduce the overall thickness of the box door 1 and the cabinet door 2, and moreover, the sliding module 5 is hidden in the groove 11. When the cabinet door 2 moves relative to the box door 1, the user can only observe the movement of the cabinet door 2 relative to the box door 1 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 box door 1. 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 as a fully embedded type, it is necessary to set the cabinet door 2 on the outside of the box door 1. The sliding module 5 is arranged in the groove 11 on the box door 1, which can ensure the aesthetics of the cabinet door 2 when the box door 1 and the cabinet door 2 move relative to each other.

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

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

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

[0142] In the third aspect, such 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 as described above. The box body 6 has a storage compartment, and the box door 1 is rotatably provided on the box body 6 to open or close the storage compartment.

[0143] 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.

[0144] 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 body around the refrigeration device. 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 body around the refrigeration device when closed.

[0145] 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 body around the refrigeration device during both opening and closing, greatly improving the usability. 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.

[0146] The refrigeration device in this application is, for example, applied as a refrigerator. However, 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.

[0147] 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 by the scope of the claims of the present utility model.
