In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

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

[0067] In the first aspect, as Figure 1 and Figure 2 shown, the embodiments of the present utility model provide a sliding door mechanism applied to a refrigeration equipment. The refrigeration equipment includes a box body 6 and a box door 1. The box door 1 is rotatably connected to the box body 6 through a hinge shaft 71. The sliding door mechanism includes: a driving component 3 and a transmission component 4.

[0068] The driving component 3 includes a tooth portion 31 and a driving gear 32. The tooth portion 31 is configured to be disposed on one side of the hinge shaft 71 of the box body 6 of the refrigeration equipment and extend circumferentially relative to the hinge shaft 71. The driving gear 32 is configured to be rotatably disposed on the box door 1 of the refrigeration equipment and mesh with the tooth portion 31.

[0069] The transmission component 4 is configured to be disposed between the driving gear 32 and the cabinet door 2 of the refrigeration equipment.

[0070] During the process of the box door 1 opening or closing the box body 6, the driving gear 32 rotates under the transmission relative to the tooth portion 31, and then drives the transmission component 4 to drive the cabinet door 2 to move along the width direction of the box door 1.

[0071] It can be understood that, as Figure 11 shown, a hinge 7 is installed at the hinge shaft 71 of the box body 6. An articulated shaft is provided on the hinge 7, and the box door 1 is rotatably arranged on the articulated shaft to realize the opening or closing of the box door 1 relative to the box body 6.

[0072] In this embodiment, the tooth portion 31 is disposed on one side of the hinge shaft 71 of the box body 6, that is, on one side of the hinge shaft. When the box door 1 rotates relative to the hinge shaft, during the rotation of the box door 1, the tooth portion 31 and the hinge shaft always remain in a fixed state. When the box door 1 rotates relative to the hinge shaft, the box door 1 also rotates relative to the tooth portion 31. Based on the meshing of the tooth portion 31 and the driving gear 32, the rotation of the driving gear 32 is driven.

[0073] Specifically, the tooth portion 31 can be a tooth ring circumferentially arranged around the hinge shaft 71 of the box body 6, or a partial tooth ring, as long as it is ensured that the tooth portion 31 meshes with the driving gear 32.

[0074] The transmission component 4 is used to convert the rotational motion of the driving gear 32 into a linear motion and drive the linear movement of the cabinet door 2 relative to the box door 1.

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

[0076] In practical applications, during the opening process of the cabinet door 1, the cabinet door 1 drives the driving gear 32 to rotate relative to the tooth part 31. The driving gear 32 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, so as to 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 driving gear 32 to rotate relative to the tooth part 31. The driving gear 32 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, so as to 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.

[0077] For the sliding door mechanism shown in this embodiment, by providing a tooth part 31 on one side of the hinge shaft 71 of the box body 6, rotatably arranging a driving gear 32 on the cabinet door 1, meshing the tooth part 31 and the driving gear 32, and arranging a transmission component 4 between the driving gear 32 and the cabinet door 2. When the cabinet door 1 is opened, the cabinet door 1 drives the driving gear 32 to rotate relative to the tooth part 31. The driving gear 32 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, so that the cabinet door 2 and the cabinet body on the side can avoid interference with the cabinet body. When the cabinet door 1 is closed, the cabinet door 1 drives the driving gear 32 to rotate relative to the tooth part 31. The driving gear 32 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, 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.

[0078] In some embodiments, as Figure 1 shown, the tooth part 31 includes an arc-shaped rack. The tooth surface of the arc-shaped rack faces the driving gear 32 and extends circumferentially relative to the hinge shaft 71.

[0079] During the process of the cabinet door 1 opening or closing the box body 6, the driving gear 32 rolls along the extending direction of the tooth surface relative to the arc-shaped rack.

[0080] It can be understood that the arc-shaped rack is arranged at the top of the box body 6, and the tooth surface of the arc-shaped rack is meshed with the driving gear 32.

[0081] During the process of the cabinet door 1 opening or closing, the cabinet door 1 rotates relative to the box body 6. The cabinet door 1 drives the driving gear 32 to rotate, while the position of the arc-shaped rack meshed with the driving gear 32 remains unchanged. Furthermore, the driving gear 32 rolls circumferentially relative to the arc-shaped rack along the hinge shaft 71, so that the driving gear 32 drives the transmission component 4 to drive the cabinet door 2 to move along the width direction of the cabinet door 1.

[0082] In this embodiment, an arc-shaped rack is provided on the tooth part 31. During the opening and closing process of the cabinet door 1, the driving gear 32 is driven to roll relative to the arc-shaped rack. The arc-shaped rack has a relatively small set area, enabling a compact design of the tooth part 31 on the cabinet body 6. Moreover, the arc-shaped rack can accurately control the rolling displacement of the driving gear 32, which is beneficial to the precise adjustment of the cabinet door 2 in the width direction of the cabinet door 1.

[0083] In some embodiments, as Figure 1 shown, the transmission assembly 4 includes: a transmission rack 42 that extends in the width direction and is configured to be connected to the cabinet door 2; a part of the transmission rack 42 meshes with the driving gear 32, and another part of the driving gear 32 meshes with the tooth part 31.

[0084] It can be understood that the transmission rack 42 is used to convert the rotational motion of the driving gear 32 into a linear motion and can drive the cabinet door 2 to move in the width direction of the cabinet door 1.

[0085] During the opening or closing process of the cabinet door 1, the cabinet door 1 rotates relative to the cabinet body 6, and the cabinet door 1 drives the driving gear 32 to rotate. While the position of the tooth part 31 meshing with the driving gear 32 remains unchanged, the driving gear 32 rotates circumferentially along the hinge axis 71 relative to the tooth part 31, so that the driving gear 32 drives the transmission rack 42 to drive the cabinet door 2 to move in the width direction of the cabinet door 1. The structure of the transmission rack 42 is simple and easy to install and maintain.

[0086] In some embodiments, as Figure 2 shown, the transmission assembly 4 includes: a gear set and a transmission rack 42. The gear set is configured to be arranged on the cabinet door 1. The transmission rack 42 extends in the width direction and is configured to be connected to the cabinet door 2; the driving gear 32 is in transmission connection with the transmission rack 42 through the gear set.

[0087] It can be understood that the driving gear 32 is in transmission connection with the transmission rack 42 through the gear set. During the opening or closing process of the cabinet door 1, the cabinet door 1 rotates relative to the cabinet body 6, and the cabinet door 1 drives the driving gear 32 to rotate. When the position of the tooth part 31 remains unchanged, the driving gear 32 rotates relative to the tooth part 31, and then drives the gear set to rotate. The gear set drives the transmission rack 42 to move in the width direction of the cabinet door 1, thereby driving the cabinet door 2 to move in the width direction of the cabinet door 1.

[0088] Specifically, the gear set of this embodiment includes two gears, and both gears are rotatably arranged on the cabinet door 1. One of the two gears is meshed with the driving gear 32, the two gears are meshed with each other, and the other of the two gears is meshed with the rack. Through the meshing transmission of the driving gear 32 with the two gears and the transmission rack 42, the driving of the transmission rack 42 is realized.

[0089] In some embodiments, such as Figure 2 shown, the gear set includes: a transmission gear 41, the transmission gear 41 is coaxially connected to the driving gear 32, and is configured to be rotatably disposed on the cabinet door 1, and the transmission gear 41 is meshed with the transmission rack 42.

[0090] It can be understood that along the axial direction of the driving gear 32, the transmission gear 41 is disposed on one side of the driving gear 32, and the transmission gear 41 is coaxially disposed with the driving gear 32. The transmission gear 41 and the driving gear 32 rotate synchronously. Since the driving gear 32 is meshed with the tooth portion 31 and the transmission gear 41 is meshed with the transmission rack 42, the rotation of the driving gear 32 is transmitted to the transmission rack 42 through the transmission gear 41.

[0091] In this embodiment, by coaxially connecting the transmission gear 41 and the driving gear 32 and meshing the transmission gear 41 with the transmission rack 42, the transmission gear 41 and the driving gear 32 can be set to different sizes to achieve the required speed ratio or torque ratio. Moreover, the space design can be made more compact.

[0092] In some embodiments, such as Figure 2 shown, the diameter of the transmission gear 41 is larger than the diameter of the driving gear 32.

[0093] It can be understood that in this embodiment, the diameter of the transmission gear 41 is larger than the diameter of the driving gear 32. The driving gear 32 with a relatively small diameter rotates and drives the transmission gear 41 with a relatively large diameter, so that the rotation speed of the transmission gear 41 is reduced, and the moving speed of the cabinet door 2 relative to the cabinet door 1 is less than the rotation speed of the cabinet door 1, which is beneficial to accurately controlling the moving speed of the cabinet door 2. At the same time, when the transmission gear 41 and the driving gear 32 rotate by the same angle, the rotation arc length of the transmission gear 41 corresponding to the same rotation angle is greater than the rotation arc length of the driving gear 32. Therefore, the transmission gear 41 can drive the transmission rack 42 to move a longer stroke, which is more beneficial to controlling the moving distance of the cabinet door 2.

[0094] In some embodiments, such as Figures 5 to 10 shown, the sliding door mechanism further includes: a sliding module 5. 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.

[0095] It can be understood that due to the self-gravity of the cabinet door 2, the cabinet door 2 may vibrate or tilt during the process of moving relative to the cabinet door 1. 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 cabinet door 1.

[0096] 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 mounted on the cabinet door 1, and the second sliding member can be mounted on the door 2. Alternatively, the first sliding member can be mounted on the door 2, and the second sliding member can be mounted on the cabinet door 1. The sliding module 5 realizes the relative movement of the cabinet door 1 and the door 2 through the relative sliding of the first sliding member and the second sliding member.

[0097] In some embodiments, as Figure 6 and Figure 7 shown, the sliding module 5 includes: a slide rail 51 and a moving member; the slide rail 51 is configured to be disposed on the cabinet door 1 and extend in the width direction. The moving member is movably disposed on the slide rail 51 in the width direction and is configured to be connected to the door 2.

[0098] It can be understood that the slide rail 51 can be in the form of a chute structure, and the moving member is correspondingly in the form of a structure that slides along the chute; the slide rail 51 can also be in the form of a slide bar; the moving member is correspondingly in the form of a structure that wraps the slide rail and moves.

[0099] The moving member can move along the extension direction of the slide rail 51. Based on the guiding and supporting functions 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 door 2 can move stably and reliably along the width direction of the cabinet door 1.

[0100] At the same time, the detachable connection between the moving member and the door 2 facilitates the installation of the 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.

[0101] Optionally, the detachable connection between the moving member and the door 2 can be achieved by fasteners, or by snap connection, or by magnetic connection.

[0102] In some embodiments, as Figure 5 shown, there are at least two sets of sliding modules 5. One end of the transmission component 4 is connected to the driving gear 32, and the other end is connected to the moving member of one of the at least two sets of sliding modules 5.

[0103] 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 gear 32.

[0104] 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 rack 42, so that the driving assembly 3 can control the transmission rack 42 to drive the moving part to move along the slide rail 51. Furthermore, the driving assembly 3 can control the transmission rack 42 to drive the cabinet door 2 to move relative to the box door 1 along the extending direction of the slide rail 51. The sliding module 5 connected to the transmission rack 42 serves as an active driving mechanism, realizing the cooperative design of the driving assembly 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 movement and 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 facilitating the precise control and smooth movement of the cabinet door 2.

[0105] 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 rack 42. 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.

[0106] 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.

[0107] In some embodiments, as Figure 6 and Figure 7 shown, the moving part includes a sliding part 52 and a hanging part 53; the sliding part 52 is movably arranged on the slide rail 51 along the width direction, and the hanging part 53 is configured to be detachably connected to the cabinet door 2 and is hung on the sliding part 52.

[0108] 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.

[0109] Furthermore, 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 sliding 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 sliding rail 51 to move on the sliding 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 sliding 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.

[0110] Optionally, as Figure 6 shown, the sliding module 5 is an active driving mechanism. The sliding module 5 is connected to the driving component 3. In this embodiment, a transmission rack 42 is fixedly connected to the sliding body 521. The transmission rack 42 is meshed with a transmission gear 41. The driving gear 32 is connected to the transmission gear 41, so that the driving gear 32 can control the transmission component 4 to drive the movement of the sliding body 521.

[0111] In some embodiments, as Figures 6 to 10 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. The hanging part 532 is hung on the sliding member 52.

[0112] 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.

[0113] 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.

[0114] 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-down 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-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. Screws can be arranged 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.

[0115] As Figure 9 and Figure 10 shown, the process of installing the hanging member 53 on the cabinet door 2 is as follows:

[0116] 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 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, 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, 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.

[0117] In the second aspect, as Figure 3 and Figure 4 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 rotatably arranged on the cabinet body 6 of the refrigeration equipment to open or close the storage compartment in the cabinet 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.

[0118] 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.

[0119] Specifically, since the door body assembly includes a sliding door mechanism, and the specific structure of the sliding door mechanism refers to the above-mentioned embodiment, the door body assembly shown in this embodiment includes all the technical solutions of the above-mentioned embodiment. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above-mentioned embodiment, which will not be elaborated here one by one.

[0120] 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.

[0121] 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 using the sliding door mechanism to connect the cabinet door 1 and the cabinet door 2, 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 along the width direction, so that the cabinet door 2 can avoid the side cabinet body, 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.

[0122] 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.

[0123] 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.

[0124] In some embodiments, as Figure 12 shown, the door body assembly is provided with the above-mentioned sliding door mechanism, the cabinet door 1 is provided with a groove 11, and the sliding module 5 is arranged in the groove 11.

[0125] The door body assembly further includes a decorative member; the decorative member is used to cover the notch end of the groove 11.

[0126] It is understandable that the sliding module 5 is arranged in the groove 11, which enables the cabinet door 1 to form a stable cooperation with the sliding module 5 during the opening and closing processes of the cabinet door 1, reducing the overall thickness of the cabinet door 1 and the cabinet door 2. Moreover, the sliding module 5 is hidden in the groove 11. When the cabinet door 2 moves relative to the cabinet door 1, users can only observe the movement of the cabinet door 2 relative to the cabinet door 1 and cannot see the sliding of the sliding module 5, enhancing the aesthetics and consistency during the movement of the cabinet door 2.

[0127] In this embodiment, four grooves 11 are provided, and the four grooves 11 are respectively arranged at the four corners of the cabinet door 1. A number 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.

[0128] When the refrigeration equipment is installed in a fully built-in manner, a cabinet door 2 needs to be arranged on the outer side of the cabinet door 1. The sliding module 5 is arranged in the groove 11 on the cabinet door 1, which can ensure the aesthetics of the cabinet door 2 when the cabinet door 1 and the cabinet door 2 move relative to each other.

[0129] When the refrigeration equipment is installed in a flush-built manner, the cabinet door 2 does not need to be installed on the outer side of the cabinet door 1. In order to ensure the aesthetics of the outer side of the cabinet door 1, a decorative piece is covered on the groove 11 to ensure the aesthetics of the appearance of the refrigeration equipment.

[0130] Specifically, the decorative piece can be a decorative cover with the same material and color as the cabinet door 1.

[0131] Users can choose whether to install the cabinet door 2 according to actual needs and select a suitable connection method according to different application scenarios.

[0132] In the third aspect, as Figure 11 and Figure 12 shown, an embodiment of the present invention further provides a refrigeration equipment, including: a box body 6 and the door body assembly as above. The box body 6 has a storage compartment, and the cabinet door 1 is rotatably arranged on the box body 6 to open or close the storage compartment.

[0133] Specifically, since the refrigeration equipment includes a door body assembly, and the specific structure of the door body assembly refers to the above embodiment, the refrigeration equipment 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.

[0134] It is understandable that during the opening process of the cabinet 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 surrounding cabinet body of the refrigeration equipment. During the closing process of the cabinet 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 surrounding cabinet body of the refrigeration equipment when closed.

[0135] The combination of the cabinet door 1 and the cabinet door 2 enables the refrigeration equipment to avoid interference between the cabinet door 2 and the cabinet body around the refrigeration equipment when opening and closing, greatly improving the usability. Especially in a restricted kitchen environment, this design advantage is more obvious. In addition, the sliding door mechanism is provided to enable the cabinet door 2 to move smoothly during the opening and closing processes, improving the service life and stability of the refrigerator.

[0136] In some embodiments, as Figure 10 shown, the door body assembly and the cabinet body 6 are configured to be disposed in the accommodation space between the first cabinet body 8 and the second cabinet body 9.

[0137] 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 first cabinet body 8 or the second cabinet body 9.

[0138] It can be understood 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 body assembly and the cabinet body 6 to be integrally embedded in the cabinet body. During the process of the cabinet 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 to move a preset distance on the cabinet door 1 in a direction away from or close to the cabinet 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.

[0139] During the process of the cabinet 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 to move on the cabinet door 1 in a direction away from or close to the cabinet 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 cabinet door 1 can be smoothly opened or closed without colliding or jamming with the side walls of the cabinet body.

[0140] For example, during the opening process of the cabinet door 1, the sliding door mechanism drives the cabinet door 2 to move a preset distance along the cabinet 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 cabinet door 1 to be fully opened, facilitating users to access items.

[0141] Similarly, during the closing process of the cabinet door 1, the sliding door mechanism drives the cabinet door 2 to move a preset distance along the cabinet door 1 in a direction close to the hinge 7. In this way, the cabinet door 2 can smoothly avoid the side wall of the first cabinet body 8, enabling the cabinet door 1 to be fully closed, maintaining the overall aesthetics and sealing performance.

[0142] In some embodiments, as Figure 10 shown, the cabinet door 2 can move relative to the cabinet door 1 between a first position and a second position in the width direction.

[0143] 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 axis 71 approaches the hinge axis 71.

[0144] 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 axis 71 moves away from the hinge axis 71 to avoid the side wall of the first cabinet body 8 or the second cabinet body 9.

[0145] It can be understood that the storage compartment is used to store items to be refrigerated or frozen. The hinge axis 71 is located on the hinge 7. When the box door 1 closes the storage compartment, the box door 1 is in a closed state. 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 block the box door 1, ensuring that the door body of the accommodation space exposed by the refrigeration device is consistent with the surrounding first cabinet door 2 and second cabinet door 2 in appearance.

[0146] 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 avoid collision or interference between the cabinet door 2 and the first cabinet body 8 or the second cabinet body 9 caused by the opening of the box door 1.

[0147] The refrigeration device in this application is applied as a refrigerator, for example. 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.

[0148] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered within the scope of the claims of the present invention.
