In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. 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.

[0056] The following combines Figures 1 to 11 , and 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.

[0057] 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, and includes: a gear assembly 3 and a transmission assembly 4; the gear assembly 3 includes a fixed gear 31 and a rotating gear 32, the rotating gear 32 is configured to be rotatably arranged on the cabinet door 1 of the refrigeration equipment and is meshed with the fixed gear 31; the fixed gear 31 is configured to be arranged at the corresponding hinge position of the cabinet door 1; the transmission assembly 4 is configured to be arranged between the rotating gear 32 and the cabinet door 2; wherein, the rotating gear 32 is used to rotate relative to the fixed gear 31 under the drive of the cabinet door 1, and further control the transmission assembly 4 to drive the cabinet door 2 to move along the width direction of the cabinet door 1.

[0058] It can be understood that the box body 6 is provided with a hinge 7, and an articulated shaft is arranged on the hinge 7, and the cabinet door 1 is rotatably arranged on the articulated shaft to realize the opening or closing of the cabinet door 1 relative to the box body 6.

[0059] The fixed gear 31 of this embodiment is arranged at the hinge position of the door 1, that is, the fixed gear 31 is sleeved on the outer wall of the hinge shaft. During the rotation of the door 1, the fixed gear 31 and the hinge shaft always remain stationary. When the door 1 rotates relative to the hinge shaft, the door 1 also rotates relative to the fixed gear 31. Based on the meshing of the fixed gear 31 and the rotating gear 32, the rotation of the rotating gear 32 is driven.

[0060] The transmission component 4 is used to convert the rotational motion of the rotating gear 32 into a linear motion and drive the door 2 to move linearly relative to the door 1.

[0061] Optionally, the transmission component 4 can be a crank-slider mechanism or a lead screw mechanism.

[0062] In practical applications, during the opening process of the door 1, the door 1 drives the rotating gear 32 to rotate relative to the fixed gear 31. The rotating gear 32 controls the transmission component 4 to drive the door 2 to move away from the hinge 7 along the width direction of the door 1, that is, move to the left relative to the door 1. In this way, interference between the door 2 and the cabinet around the refrigeration equipment can be avoided; during the closing process of the door 1, the door 1 drives the rotating gear 32 to rotate relative to the fixed gear 31. The rotating gear 32 controls the transmission component 4 to drive the door 2 to move towards the hinge 7 along the width direction of the door 1, that is, move to the right relative to the door 1. In this way, it can be ensured that the door 2 can avoid the cabinet around the refrigeration equipment when the door 1 is closed and the door 2 is reset.

[0063] For the sliding door mechanism shown in this embodiment, by arranging the fixed gear 31 at the corresponding hinge position of the door 1, arranging the rotating gear 32 on the door 1 in a rotating manner, meshing the fixed gear 31 and the rotating gear 32, and arranging the transmission component 4 between the rotating gear 32 and the door 2. When the door 1 is opened, the door 1 drives the rotating gear 32 to rotate relative to the fixed gear 31. The rotating gear 32 controls the transmission component 4 to drive the door 2 to move away from the hinge 7 along the width direction of the door 1, so that the door 2 and the cabinet on the side are prevented from interfering with the cabinet. When the door 1 is closed, the door 1 drives the rotating gear 32 to rotate relative to the fixed gear 31. The rotating gear 32 controls the transmission component 4 to drive the door 2 to move towards the hinge 7 along the width direction of the door 1, so that the door 2 returns to its original position, ensuring that the door 2 does not interfere with the cabinet around the refrigeration equipment.

[0064] In some embodiments, such as Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the transmission assembly 4 includes a transmission gear 41 and a transmission rack 42; the transmission gear 41 is respectively meshed with the rotating gear 32 and the transmission rack 42, and the transmission gear 41 is configured to be rotatably arranged on the door 1, and the transmission rack 42 extends in the width direction and is connected to the cabinet door 2.

[0065] It can be understood that the transmission gear 41 of this embodiment is meshed with the rotating gear 32, and moreover, the transmission rack 42 is meshed with the transmission gear 41. When the door 1 rotates relative to the box body 6, the door 1 drives the rotating gear 32 to rotate relative to the fixed gear 31, and the transmission gear 41 also rotates, thereby driving the transmission rack 42 to move in the width direction and driving the cabinet door 2 to move along the width direction of the door 1.

[0066] In this embodiment, by setting the transmission assembly 4 as the transmission gear 41 and the transmission rack 42, the structure is simple, easy to install and maintain, and can improve the transmission efficiency to a high level.

[0067] In some embodiments, as Figure 5 shown, the gear ratio of the transmission gear 41 and the rotating gear 32 is greater than the gear ratio of the rotating gear 32 and the fixed gear 31.

[0068] It can be understood that the gear ratio of two gears refers to the ratio of the number of teeth of the driving gear and the driven gear. The gear ratio determines the relationship between the rotational speeds of the two gears during rotation, and the gear ratios of two gear sets determine the deceleration effects of the corresponding gear sets.

[0069] The gear ratio of the transmission gear 41 and the rotating gear 32 in this embodiment is greater than the gear ratio of the rotating gear 32 and the fixed gear 31, which means that when transmitting rotational motion, the deceleration effect generated by the transmission gear 41 and the rotating gear 32 is more significant than the deceleration effect generated by the rotating gear 32 and the fixed gear 31, that is, the transmission gear 41 and the rotating gear 32 rotate slower relative to the rotating gear 32 and the fixed gear 31, so that the rotation of the transmission gear 41 relative to the door 1 is slower, and thus when the transmission gear 41 cooperates with the transmission rack 42, the movement of the transmission rack 42 can be slower and more stable, ensuring the stability and reliability of the movement of the cabinet door 2 relative to the door 1.

[0070] In some embodiments, as Figure 5 shown, the gear assembly 3 and the transmission gear 41 are arranged side by side on the top surface of the door 1.

[0071] It is understandable that the gear assembly 3 and the transmission gear 41 of this embodiment are arranged side by side on the top surface of the cabinet door 1, so that the gear assembly 3 and the transmission gear 41 transmit the rotation of the cabinet door 1 through transmission and convert it into the movement of the cabinet door 2. And the side-by-side arrangement makes the entire transmission structure compact, the transmission space is small and located on the top surface of the cabinet door 1, without affecting the aesthetic appearance of the cabinet body 6.

[0072] In some embodiments, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 shown, the sliding door mechanism further includes: a sliding module 5.

[0073] The sliding module 5 is configured to be arranged 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.

[0074] It is understandable that due to the self-gravity 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 to guide the reliable and stable movement of the cabinet door 2 relative to the cabinet door 1.

[0075] 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 matched 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.

[0076] In some embodiments, such as Figure 7 and Figure 8 shown, the sliding module 5 includes a slide rail 51 and a moving member; the slide rail 51 is configured to be arranged on the cabinet door 1 and extend in the width direction; the moving member is movably arranged on the slide rail 51 in the width direction, and the moving member is configured to be detachably connected to the cabinet door 2.

[0077] It is understandable 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.

[0078] The moving member can move along the extending 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. And 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.

[0079] Meanwhile, the detachable connection between the moving part 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.

[0080] Optionally, the detachable connection between the moving part and the cabinet door 2 can be achieved through fasteners, snap connections, or magnetic connections.

[0081] In some embodiments, as Figure 5 and Figure 6 shown, there are at least two sets of sliding modules 5. One end of the transmission component 4 is connected to the gear component 3, and the other end is connected to the moving part of one of the at least two sets of sliding modules 5 to drive the moving part to move along the slide rail 51.

[0082] It can be understood that there can be multiple sets of sliding modules 5. One set of sliding modules 5 is used to connect with the transmission component 4, so that the gear component 3 can control the transmission component 4 to drive the moving part to move along the slide rail 51. Furthermore, the gear 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 to the transmission component 4 serves as the active driving mechanism to realize the cooperative design of the gear 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 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 facilitating the precise control and smooth movement of the cabinet door 2.

[0083] Specifically, in this embodiment, there are four sets of sliding modules 5. Two sets of 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, among the two sets of sliding modules 5 located at the upper end, the set closer to the hinge 7 is connected to the transmission component 4. The remaining three sets of sliding modules 5 are distributed in the remaining triangles of the box door 1. The slide rails 51 in the four sets of sliding modules 5 are arranged in parallel.

[0084] 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.

[0085] In some embodiments, as Figure 5 、 Figure 7 and Figure 8As shown, the moving member includes a sliding member 52 and a hanging member 53; the sliding member 52 is movably disposed on the slide rail 51 in the width direction, and the hanging member 53 is configured to be connected to the cabinet door 2 and is hung on the sliding member 52.

[0086] It can be understood that the hanging member 53 is used to connect the sliding member 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 member 52, and the hanging member 53 is configured to be detachably connected to the cabinet door 2.

[0087] Further, the sliding member 52 of this embodiment includes a sliding body 521 and an adapter seat 522. The sliding body 521 and the adapter seat 522 are fixedly connected. A support frame 511 is provided on the slide rail 51, and a round hole is provided on the support frame 511. 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 seat 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 member. 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.

[0088] Optionally, as Figure 7 shown, the sliding module 5 is an active driving mechanism, and the sliding module 5 is connected to the transmission component 4. In this embodiment, a transmission rack 42 is fixedly connected to the sliding body 521, the transmission rack 42 is meshed with the transmission gear 41, and the rotating gear 32 is connected to the transmission gear 41, so that the rotating gear 32 can control the transmission component 4 to drive the movement of the sliding body 521.

[0089] In some embodiments, as Figures 7 to 11 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 disposed 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.

[0090] 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, so that the position deviation between the cabinet door 2 and the box door 1 can be adjusted by adjusting the relative position between the hanging part 532 and the fixed seat 531, 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 aesthetics of the installation of the box door 1 and the cabinet door 2.

[0091] Specifically, the fixing base 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 fixing base 531 for accommodating the hanging member 532; the hanging member 532 is slidably arranged in the installation groove, and a first clamping joint 5321 is formed on the hanging member 532 to adjust the relative position between the cabinet door 2 and the box door 1 by adjusting the position of the hanging member 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.

[0092] Specifically, as Figure 7 and Figure 9 shown, the first clamping joint 5321 is a U-shaped hook facing downward and can slide through the notch into the first clamping groove 5221. A first rectangular hole extending in the up-down direction is provided on the hanging member 532, and the fixing base 531 is provided with two installation holes and an installation groove extending left and right between the two installation holes. A second rectangular hole extending in the left-right direction is provided on the side wall of the installation groove. The hanging member 532 can slide in the installation groove. By controlling the position of the hanging member 532 in the installation groove, the hanging member 532 can be moved up and down relative to the fixing base 531. Screws can be set to pass through the first rectangular hole on the installation groove and the second rectangular hole on the hanging member 532, and a hanging member 532 that can be adjusted in both the up-down and left-right directions can be formed. And through the relative position between the installation 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.

[0093] As Figure 10 and Figure 11 shown, the process of installing the hanging member 53 on the cabinet door 2 is as follows:

[0094] Thread the hanging member 532 through the installation 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 connect the fixing base 531 as a whole to the cabinet door 2. Hang the first clamping joint 5321 on the hanging member 532 that has been connected in the first clamping groove 5221 to complete the connection between the hanging member 532 and the adapter base 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 screws 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 installation 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.

[0095] In a second aspect, as Figure 1 shown, an embodiment of the present utility model further provides a door assembly, including: a cabinet door 1, a door panel 2, and a sliding door mechanism. The cabinet door 1 is configured to be rotatably disposed on a cabinet body 6 of a refrigeration device to open or close a storage compartment in the cabinet body 6; the door panel 2 is movably disposed on the cabinet door 1 along the width direction of the cabinet door 1; and the sliding door mechanism is the sliding door mechanism as described above.

[0096] Wherein, 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 door panel 2 is 12 - 26 mm. For example, the thickness of the door panel 2 can be 12 mm, 15 mm, 20 mm, or 26 mm; and the door panel 2 can be a wooden door panel or a plastic door panel.

[0097] Specifically, since the door assembly includes a sliding door mechanism, and the specific structure of the sliding door mechanism refers to the above embodiment, the door assembly shown in this embodiment includes all the technical solutions of the above embodiment. Therefore, it has at least all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be elaborated herein one by one.

[0098] It can be understood that the door 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 door panel 2 to move relative to the cabinet door 1.

[0099] For the door assembly shown in this embodiment, by rotatably connecting the cabinet door 1 to the cabinet body 6, movably disposing the door panel 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 door panel 2, during the opening or closing process of the sliding door mechanism, the movement of the door panel 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 door panel 2 and the outside when the cabinet door 1 rotates, and meeting the usage requirements of users in different scenarios.

[0100] Specifically, during the movement of the door panel 2 relative to the cabinet door 1, the door panel 2 can move left and right relative to the cabinet door 1 along the width direction.

[0101] Such a design not only improves the convenience of use, but also can avoid possible damage to the door assembly during use. At the same time, this design also enables the refrigeration device to better integrate into the home environment, achieving the effects of overall aesthetics and sealing.

[0102] In some embodiments, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the door assembly and the cabinet body 6 are configured to be disposed in an accommodation space between a first cabinet 8 and a second cabinet 9.

[0103] 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 avoids the side wall of the first cabinet body 8 or the second cabinet body 9.

[0104] It can be understood that an opening is provided on the outer side of the accommodating space between the first cabinet body 8 and the second cabinet body 9. This design enables the door 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 accommodating 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 towards the cabinet body 6 so that the cabinet door 2 avoids the side walls of the first cabinet body 8 and the second cabinet body 9.

[0105] During the process of the cabinet door 1 passing through the opening to control the opening or closing of the accommodating 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 towards the cabinet body 6, and is also capable of controlling 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 wall of the cabinet body.

[0106] 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.

[0107] 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 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 cabinet door 1 to be fully closed, maintaining the overall aesthetics and sealing performance.

[0108] In some embodiments, as Figure 2 、 Figure 3 and Figure 4 shown, the cabinet door is rotatably connected to the cabinet body through a hinge; the cabinet door 2 can move between a first position and a second position relative to the cabinet door 1 in the width direction.

[0109] When the cabinet door 2 is in the first position, the cabinet 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.

[0110] When the cabinet door 2 is in the second position, the cabinet 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.

[0111] It is understandable that the interior of the storage room is used to store items to be refrigerated or frozen. When the box door 1 closes the storage room, 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 8 and second cabinet 9 in appearance.

[0112] When the box door 1 opens the storage room, 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 8 or the second cabinet 9, so as to avoid collision or interference between the cabinet door 2 and the first cabinet 8 or the second cabinet 9 caused by the opening of the box door 1.

[0113] In some embodiments, as Figure 5 shown, the door body assembly is provided with the above-mentioned sliding door mechanism. The box door 1 is provided with a groove 11, and the sliding module 5 is arranged in the groove 11.

[0114] The door body assembly further includes a decorative member; the decorative member is used to cover the notch end of the groove 11.

[0115] It is understandable 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, reducing the overall thickness of the box 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 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.

[0116] 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 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.

[0117] When the refrigeration device is fully embedded, 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.

[0118] When the refrigeration device is flush embedded, it is not necessary to install the cabinet door 2 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 of the refrigeration device.

[0119] Specifically, the decorative member can be a decorative cover with the same material and color as the door 1 of the cabinet.

[0120] 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.

[0121] In a third aspect, as Figure 1 , Figure 2 and Figure 3 shown, an embodiment of the present utility model further provides a refrigeration device, including: a 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.

[0122] 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.

[0123] It can be understood that during the opening process of the box door 1, the sliding door mechanism driving the cabinet door 2 to move away from the hinge 7 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.

[0124] 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 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.

[0125] 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.

[0126] 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.
