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.

[0063] The following is combined with Figures 1 to 10, 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.

[0064] In the first aspect, as Figure 1 , Figure 2 and Figure 3 shown, the embodiments of the present utility model provide a sliding door mechanism, which is applied to a refrigeration equipment. The refrigeration equipment includes a box body and a box door, and the box door is rotatably arranged on the box body, and includes: a rack assembly 3, a gear assembly 4 and a driving member 5.

[0065] The rack assembly 3 includes a first rack 31 and a second rack 32. The first rack 31 is configured to be arranged on the box door 1 of the refrigeration equipment, and the second rack 32 is configured to be arranged on the cabinet door 2. Both the first rack 31 and the second rack 32 extend along the width direction of the box door 1.

[0066] The gear assembly 4 meshes between the first rack 31 and the second rack 32.

[0067] The driving member 5 is arranged on the box body 8, is connected to the gear assembly 4, and is used to drive the gear assembly 4 to move relative to the box door 1 in the width direction during the opening and closing of the box door 1.

[0068] Wherein, the second rack 32 is used to drive the cabinet door 2 to move along the direction opposite to the driving direction of the driving member 5 under the transmission of the gear assembly 4.

[0069] It can be understood that, as Figure 3 shown, the box body 8 is provided with a hinge 9, and an articulated shaft is arranged on the hinge 9. 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 8.

[0070] The driving member 5 of this embodiment can, along with the opening or closing of the box door 1, synchronously drive the gear assembly 4 to approach the hinge 9 or move away from the hinge 9 relative to the box door 1 in the width direction, and then drive the second rack 32 to approach the hinge 9 or move away from the hinge 9 in the width direction, so that the cabinet door 2 can approach the hinge 9 or move away from the hinge 9 in the width direction.

[0071] In practical applications, during the opening process of the cabinet door 1, the cabinet door 1 rotates counterclockwise around the hinge axis, and the driving member 5 drives the gear assembly 4 to move closer to the hinge 9 in the width direction. Under the meshing action of the gear assembly 4 with the first rack 31 and the second rack 32, the gear assembly 4 drives the second rack 32 to move away from the hinge 9 in the width direction, thereby driving the cabinet door 2 to move away from the hinge 9 in the width direction of the cabinet door 1, that is, move to the left relative to the cabinet door 1. 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 cabinet door 1, the cabinet door 1 rotates clockwise around the hinge axis, and the driving member 5 drives the gear assembly 4 to move away from the hinge 9 in the width direction. Under the meshing action of the gear assembly 4 with the first rack 31 and the second rack 32, the gear assembly 4 drives the second rack 32 to move closer to the hinge 9 in the width direction, thereby driving the cabinet door 2 to move closer to the hinge 9 in 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 be ensured that the cabinet door 2 can avoid the cabinet body around the refrigeration equipment when the cabinet door 1 is closed, and the cabinet door 2 is reset.

[0072] Optionally, the driving member 5 can be a crank mechanism or a connecting rod assembly.

[0073] Specifically, the number of gears included in the gear assembly 4 is an even number to ensure that after the transmission of the gear assembly 4, the driving direction of the driving member 5 is opposite to the moving direction of the second rack 32 along the cabinet door 1.

[0074] For the sliding door mechanism shown in this embodiment, by arranging the first rack 31 on the cabinet door 1, the second rack 32 on the cabinet door 2, and the gear assembly 4 meshing between the first rack 31 and the second rack 32, the driving member 5 drives the gear assembly 4 to move relative to the cabinet door 1 in the width direction to drive the second rack 32 to move in the width direction of the cabinet door 1. When the cabinet door 1 is opened, the driving member 5 drives the gear assembly 4 to move closer to the hinge 9 in the width direction of the cabinet door 1. Under the transmission action of the gear assembly 4, it drives the second rack 32 to move away from the hinge 9 in the width direction of the cabinet door 1, thereby driving the cabinet door 2 to move away from the hinge 9 in 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, the driving member 5 drives the gear assembly 4 to move away from the hinge 9 in the width direction of the cabinet door 1. Under the transmission action of the gear assembly 4, it drives the second rack 32 to move closer to the hinge 9 in the width direction of the cabinet door 1, thereby driving the cabinet door 2 to move closer to the hinge 9 in the width direction of the cabinet door 1, so that the cabinet door 2 returns to its original position, ensuring that the cabinet door 2 does not interfere with the surrounding cabinet body.

[0075] In some embodiments, as Figure 2 shown, the gear assembly 4 includes: a mounting frame 41, a first gear 42, and a second gear 43.

[0076] The mounting bracket 41 is connected to the driving member 5 and is used to move along the width direction under the drive of the driving member 5.

[0077] The first gear 42 and the second gear 43 are respectively rotatably arranged on the mounting bracket 41. The first rack 31 meshes with the first gear 42, the first gear 42 meshes with the second gear 43, and the second gear 43 meshes with the second rack 32.

[0078] It can be understood that when the driving member 5 drives the mounting bracket 41 to move along the width direction, since the first gear 42 and the second gear 43 also move along the width direction under the drive of the mounting bracket 41, and based on the meshing action between the first gear 42 and the first rack 31, the first gear 42 rotates relative to the mounting bracket 41 and drives the second gear 43 meshing with the first gear 42 to rotate. Based on the meshing action between the second gear 43 and the second rack 32, the second rack 32 moves relative to the width direction of the cabinet door 1. Since the rotation directions of the first gear 42 and the second gear 43 are opposite, the moving direction of the second rack 32 is opposite to the driving direction of the driving member 5. Furthermore, when the cabinet door 1 is opened, the second rack 32 moves away from the hinge 9, and when the cabinet door 1 is closed, the second rack 32 moves towards the hinge 9.

[0079] In this embodiment, by providing the mounting bracket 41, the first gear 42 and the second gear 43 in the gear assembly 4, through the meshing of the first gear 42 and the second gear 43, the first gear 42 and the second gear 43 rotate in opposite directions, thereby realizing the movement of the cabinet door 2 relative to the hinge 9 during the opening and closing of the cabinet door 1. The structure is simple and compact and is easy to implement.

[0080] In some embodiments, as Figure 2 shown, the mounting bracket 41 is movably arranged on the cabinet door 1 along the width direction.

[0081] The driving member 5 includes a connecting rod. The first end of the connecting rod is rotatably arranged at a fixed position on the box body 8, and the second end of the connecting rod is rotatably connected to the mounting bracket 41; the fixed position is arranged offset from the hinge position of the cabinet door 1 relative to the box body 8.

[0082] Wherein, during the opening process of the cabinet door 1, the connecting rod is used to drive the mounting bracket 41 to move towards the side close to the hinge position; during the closing process of the cabinet door 1, the connecting rod is used to drive the mounting bracket 41 to move towards the side away from the hinge position.

[0083] It is understandable that the first end of the connecting rod in this embodiment is rotatably arranged on the hinge 9. When the cabinet door 1 rotates relative to the cabinet body 8 around the hinge axis, the second end of the connecting rod rotates in a circular motion with the hinge axis as the center. Since the first end of the connecting rod is arranged offset from the hinge axis, the distance between the second end of the connecting rod and the hinge 9 will change as the connecting rod rotates, thereby driving the mounting bracket 41 to move towards or away from the hinge 9 along the width direction of the cabinet door 1.

[0084] In this embodiment, by arranging the fixed position of the connecting rod on the cabinet body 8 offset from the hinge position of the cabinet body 8, the distance between the second end of the connecting rod and the cabinet body 8 changes, thereby driving the mounting bracket 41 to approach or move away from the hinge 9. As the cabinet door 1 opens and closes, the connecting rod drives the movement of the mounting bracket 41. There is no need to set up additional driving devices, and the movement of the mounting bracket 41 along the width direction is automatically driven only by the opening and closing of the cabinet door 1, and the structure is simple.

[0085] In some embodiments, as Figure 1 and Figure 2 shown, the tooth surfaces of the first rack 31 and the second rack 32 are arranged opposite to each other, and the first gear 42 and the second gear 43 are located between the first rack 31 and the second rack 32.

[0086] It is understandable that since the first rack 31 meshes with the first gear 42, the first gear 42 meshes with the second gear 43, and the second gear 43 meshes with the second rack 32, arranging the tooth surfaces of the first rack 31 and the second rack 32 opposite to each other and locating the first gear 42 and the second gear 43 between the first rack 31 and the second rack 32 can ensure that the spatial structure of the first rack 31, the first gear 42, the second gear 43, and the second rack 32 is relatively compact, and direct transmission can be achieved without adding additional transmission devices, and the number of transmission devices is the least, and the transmission efficiency is relatively high.

[0087] In some embodiments, as Figure 1 shown, the module of the first gear 42 is smaller than the module of the second gear 43.

[0088] It is understandable that the number of teeth of the second gear 43 is less than the number of teeth of the first gear 42, the transmission ratio increases, the rotational speed of the second gear 43 decreases, the moving speed of the second rack 32 becomes slower, and thus the moving speed of the cabinet door 2 relative to the cabinet door 1 decreases, ensuring the stability of the movement of the cabinet door 2.

[0089] In some embodiments, as Figure 1 and Figure 2 shown, it further includes: a guide plate 6.

[0090] The guide plate 6 is detachably arranged on the cabinet door 1.

[0091] The first rack 31 is disposed on the guide plate 6 in the width direction, and the mounting bracket 41 is movably disposed on the guide plate 6 in the width direction.

[0092] It can be understood that the guide plate 6 can be quickly installed and disassembled relative to the door 1 of the cabinet. For different cabinets 8, the same guide plate 6 can be set. When the cabinet door 2 is installed on the door 1 of the cabinet, it can be quickly realized through the assembly of the cabinet door 2 and the guide plate 6. Applicable to different specifications of the cabinet 8, the cabinet door 2 can be conveniently installed on the door 1 of the cabinet, improving the installation efficiency.

[0093] In some embodiments, as Figure 1 and Figure 2 shown, the guide plate 6 is provided with a first elongated hole 61 and a second elongated hole 62. The first elongated hole 61 and the second elongated hole 62 are arranged side by side and both extend in the width direction.

[0094] The mounting bracket 41 includes a base 411, a first fixed shaft 412 and a second fixed shaft 413; the base 411 is disposed on one side of the guide plate 6, and the first gear 42 and the second gear 43 are disposed on the other side of the guide plate 6; the first fixed shaft 412 and the second fixed shaft 413 are respectively inserted through the first elongated hole 61 and the second elongated hole 62; the first gear 42 is rotatably disposed on the first fixed shaft 412, and the second gear 43 is rotatably disposed on the second fixed shaft 413.

[0095] It can be understood that the base 411 provides an installation support for the first fixed shaft 412 and the second fixed shaft 413. Moreover, the first fixed shaft 412 and the second fixed shaft 413 can move along the first elongated hole 61 and the second elongated hole 62. The first elongated hole 61 and the second elongated hole 62 limit the movement paths of the first fixed shaft 412 and the second fixed shaft 413 in the width direction of the door 1 of the cabinet. Furthermore, the movement paths of the first gear 42 and the second gear 43 are also limited, so that the second rack 32 can move along the width direction of the door 1 of the cabinet, thus ensuring that the moving direction of the cabinet door 2 relative to the door 1 of the cabinet is along the width direction.

[0096] In this embodiment, by providing the first elongated hole 61 and the second elongated hole 62 on the guide plate 6, and setting the mounting bracket 41 as the base 411, the first fixed shaft 412 and the second fixed shaft 413, the movement directions of the first fixed shaft 412 and the second fixed shaft 413 can be limited, and the meshing and transmission of the first gear 42 and the second gear 43 are realized. The structure is compact, the movement of the mounting bracket 41 in the width direction is realized, as well as the transmission with the gear assembly 4.

[0097] In some embodiments, as Figures 4 to 9 shown, the sliding door mechanism further includes: a sliding module 7.

[0098] The sliding module 7 is configured to be disposed between the cabinet door 1 and the cabinet door 2, and the sliding module 7 is used to guide the cabinet door 2 to move relative to the cabinet door 1 in the width direction.

[0099] It can be understood 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 7 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.

[0100] The sliding module 7 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 7 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.

[0101] In some embodiments, as Figure 5 and Figure 6 shown, the sliding module 7 includes: a slide rail 71 and a moving member.

[0102] The slide rail 71 is configured to be disposed on the cabinet door 1 and extend in the width direction.

[0103] The moving member is movably disposed on the slide rail 71 in the width direction, and the moving member is configured to be detachably connected to the cabinet door 2.

[0104] It can be understood that the slide rail 71 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 71 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.

[0105] The moving member can move along the extending direction of the slide rail 71. Based on the guiding and supporting functions of the slide rail 71, the moving member can move stably and reliably along the slide rail 71. Moreover, based on the high rigidity of the slide rail 71, 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.

[0106] 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.

[0107] 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.

[0108] In some embodiments, as Figure 4As shown in the figure, there are at least two sets of sliding modules 7. The input end of the gear assembly 4 is connected to the driving member 5, the output end of the gear assembly 4 meshes with the second rack 32, and the second rack 32 is connected to the moving member of one of the at least two sets of sliding modules 7.

[0109] Among them, the gear assembly 4 is used to drive the moving member to move along the slide rail 71 under the drive of the driving member 5.

[0110] It can be understood that there can be multiple sets of sliding modules 7. One set of sliding modules 7 is used to connect with the second rack 32, so that the driving member 5 can control the gear assembly 4 to drive the moving member to move along the slide rail 71. Furthermore, the driving member 5 can control the gear assembly 4 to drive the cabinet door 2 to move relative to the box door 1 along the extension direction of the slide rail 71. The sliding module 7 connected to the second rack 32 serves as an active driving mechanism, realizing the cooperative design of the driving member 5 and the sliding module 7. For cooperative guidance, the slide rails 71 in each sliding module 7 are arranged in parallel, ensuring that the cabinet door 2 can be accurately guided during the movement process, avoiding interference with the side wall of the cabinet body. Moreover, the remaining multiple sets of sliding modules 7 serve as passive guiding mechanisms. Through the cooperation of multiple sets of sliding modules 7, 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.

[0111] Specifically, there are four sets of sliding modules 7 in this embodiment. Two sets of sliding modules 7 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 7 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 7 located at the upper end and close to the hinge 9 is connected to the gear assembly 4. The remaining three sets of sliding modules 7 are respectively arranged at the remaining triangles of the box door 1. The slide rails 71 in the four sets of sliding modules 7 are arranged in parallel.

[0112] Correspondingly, among the three sets of passive sliding modules 7, the sliding module 7 located at the upper end of the box door 1 has the same structure as the sliding module 7 located at the lower end of the box door 1 and is symmetrically arranged on the box door 1.

[0113] In some embodiments, as Figure 5 and Figure 6 shown, the moving member includes a sliding member 72 and a hanging member 73; the sliding member 72 is movably arranged along the width direction on the slide rail 71, and the hanging member 73 is configured to be connected to the cabinet door 2 and is hung on the sliding member 72.

[0114] It can be understood that the hanging member 73 is used to connect the sliding member 72 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 72. Moreover, the hanging member 73 is configured to be detachably connected to the cabinet door 2.

[0115] Further, the slider 72 of this embodiment includes a sliding body 721 and an adapter seat 722. The sliding body 721 and the adapter seat 722 are fixedly connected. A support frame 711 is provided on the slide rail 71. A round hole is provided on the support frame 711, and a ball is installed in the round hole. The sliding body 721 is in rolling contact with the slide rail 71 to move on the slide rail 71 in the width direction. A first card slot 7221 is provided on the adapter seat 722 for hanging the hanging member 73 on the sliding body 721. The relative movement between the sliding body 721 and the slide rail 71 in 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 trajectory and distance of the cabinet door 2, avoid interference with the side wall of the cabinet body, and realize the smooth opening and closing of the box door 1.

[0116] Optionally, as Figure 5 shown, the sliding module 7 is an active driving mechanism. The sliding module 7 is connected to the second rack 32. The second rack 32 is meshed with the gear assembly 4. The driving member 5 is connected to the gear assembly 4 so that the driving member 5 can control the gear assembly 4 to drive the movement of the sliding body 721.

[0117] In some embodiments, as Figures 5 to 9 shown, the hanging member 73 includes a fixed seat 731 and a hanging part 732; the fixed seat 731 is configured to be connected to the cabinet door 2, and the hanging part 732 is adjustably arranged on the fixed seat 731 in the vertical or horizontal direction, and the hanging part 732 is hung on the slider 72.

[0118] It can be understood that a slight adjustment in the vertical or horizontal direction can be achieved between the hanging part 732 and the fixed seat 731. Thus, by adjusting the relative position between the hanging part 732 and the fixed seat 731, 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.

[0119] Specifically, the fixed seat 731 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 731 for accommodating the hanging part 732; the hanging part 732 is slidably arranged in the installation groove, and a first card joint 7321 is formed on the hanging part 732 to adjust the relative position between the cabinet door 2 and the box door 1 by adjusting the position of the hanging part 732 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.

[0120] Specifically, the first clamping joint 7321 is a U-shaped hook facing downward, which can pass through the notch and slide into the first clamping groove 7221. The hanger 732 is provided with a first rectangular hole extending in the up-down direction, the fixed seat 731 is provided with two mounting holes and a mounting groove extending left and right between the two mounting holes, and the side wall of the mounting groove is provided with a second rectangular hole extending left and right. The hanger 732 can slide in the mounting groove. By controlling the position of the hanger 732 in the mounting groove, the hanger 732 can be moved up and down relative to the fixed seat 731. Screws can be set to pass through the first rectangular hole on the mounting groove and the second rectangular hole on the hanger 732, so as to form a hanger 732 that can be adjusted in both the up-down and left-right directions. And through the relative position of the mounting hole of the fixed seat 731 and the cabinet door 2, the position of the fixed seat 731 and the cabinet door 2 can be adjusted in the up-down and left-right directions.

[0121] like Figure 8 and Figure 9 As shown, the process of installing the hanging member 73 and the cabinet door 2 is as follows:

[0122] The hanging piece 732 is inserted into the mounting groove of the fixing seat 731. The fixing seat 731 is connected to the cabinet door 2 as a whole by screws through the second rectangular hole, the first rectangular hole and the cabinet door 2. The first clamping joint 7321 on the connected hanging piece 732 is hung in the first clamping groove 7221 to complete the connection between the hanging piece 732 and the adapter 722. Then, by observing the positional relationship between the cabinet door 2 and the box door 1, whether there is a deviation is detected. 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 piece 73 is separated from the cabinet door 2, and the position of the hanging piece 73 is adjusted. The cabinet door 2 and the fixing seat 731, the hanging piece 732 assembly, adjust the position of the hanging piece 732. If the positional relationship meets the requirements and does not need to be adjusted, screws are used to pass through the mounting holes on both sides of the fixing seat 731 and the cabinet door 2, and the cabinet door 2 and the fixing seat 731 are further fixed to keep its position stable. The above method can not only fine-tune the position of the fixing seat 731, but also ensure that all fixations are firm, thereby ensuring that the positional relationship between the cabinet door 2 and the box door 1 is accurate.

[0123] In the second aspect, Figure 3 As shown, the embodiment of the utility model further provides a door assembly, comprising: a box door 1, a cabinet door 2 and a sliding door mechanism. The box door 1 is rotatably arranged on the box body 8 of the refrigeration device to open or close the storage compartment in the box body 8. The cabinet door 2 is arranged on the side of the box door 1 away from the box body 8, and is movably arranged on the box door 1 along the width direction. The sliding door mechanism is the sliding door mechanism as described above.

[0124] 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 door 2 is 12 - 26 mm. For example, the thickness of the door 2 can be 12 mm, 15 mm, 20 mm or 26 mm; the door 2 can be a wooden door panel or a plastic door panel.

[0125] 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.

[0126] It can be understood that the door body assembly in the present utility model can be applied to household appliances, such as a refrigerator. During the opening or closing process of the cabinet door 1, the sliding door mechanism drives the door 2 to move relative to the cabinet door 1.

[0127] For the door body assembly shown in this embodiment, by rotatably connecting the cabinet door 1 to the cabinet body 8, arranging the door 2 movably along the width direction of the cabinet door 1 outside the cabinet door 1, and connecting the cabinet door 1 and the door 2 with a sliding door mechanism, during the opening or closing process of the sliding door mechanism, controlling the door 2 to move relative to the cabinet door 1, so that the cabinet door 1 can avoid the side cabinet body during the opening and closing processes, thereby avoiding the interference between the door 2 and the outside when the cabinet door 1 rotates, and can meet the usage requirements of users in different scenarios.

[0128] Specifically, during the movement of the door 2 relative to the cabinet door 1, the door 2 can move left and right relative to the cabinet door 1 along the width direction.

[0129] 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.

[0130] In the third aspect, as Figure 3 and Figure 10 shown, the embodiment of the present utility model also provides a refrigeration equipment, including: a cabinet body 8 and the door body assembly as above. The cabinet body 8 has a storage compartment, and the cabinet door 1 is rotatably arranged on the cabinet body 8 to open or close the storage compartment.

[0131] Specifically, since the refrigeration equipment includes a door body assembly, and the specific structure of the door body assembly refers to the above-mentioned embodiment, the refrigeration equipment 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.

[0132] It is understandable that the door 1 of the box is used to open and close the storage compartment. When the refrigeration device is installed in a fully built-in manner, in order to maintain the consistency between the refrigeration device and the surrounding cabinet, a cabinet door 2 with the same material and color as the surrounding cabinet is installed on the outside of the box door 1.

[0133] The refrigeration device of this embodiment can install the cabinet door 2 on the box door 1 through a sliding door mechanism, so that when the refrigeration device is opened and closed, interference between the cabinet door 2 and the cabinets around the refrigeration device can be avoided, greatly improving the convenience of use. 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.

[0134] In some embodiments, as Figure 3 shown, the box body 8 is configured to be disposed within the accommodation space between the first cabinet 10 and the second cabinet 11.

[0135] During the opening or closing process of the box door 1, the driving member 5 is used to change the position of the cabinet door 2 on the box door 1 so that the cabinet door 2 avoids the first cabinet 10 or the second cabinet 11.

[0136] It is understandable that an opening is provided on the outside of the accommodation space between the first cabinet 10 and the second cabinet 11. This design enables the refrigeration device to be integrally embedded in the cabinet. During the process of the box door 1 passing through the opening to control the opening or closing of the accommodation space, the driving member 5 is configured to drive the cabinet door 2 on the box door 1 to move a preset distance in a direction away from or close to the box body 8 so that the cabinet door 2 avoids the side walls of the first cabinet 10 and the second cabinet 11.

[0137] During the process of the box door 1 passing through the opening to control the opening or closing of the accommodation space, the driving member 5 is configured to drive the cabinet door 2 on the box door 1 to move in a direction away from or close to the box body 8. This design is mainly to avoid interference between the cabinet door 2 and the side walls of the first cabinet 10 and the second cabinet 11. Through the movement of the cabinet door 2, the box door 1 can be smoothly opened or closed without colliding or jamming with the side walls of the cabinet. This 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 an overall aesthetic and sealed effect.

[0138] In some embodiments, as Figure 3 shown, the box door 1 is rotatably connected to the box body 8 through a hinge 9; the cabinet door 2 can move relative to the box door 1 between a first position and a second position in the width direction.

[0139] 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 9 is disposed close to the hinge 9.

[0140] 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 9 is arranged away from the hinge 9 to avoid the side wall of the first cabinet body 10 or the second cabinet body 11.

[0141] It can be understood 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 a closed state, and the side of the cabinet door 2 is at a first distance (close to zero) relative to the hinge 9 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 to ensure that the door body of the accommodation space exposed by the refrigeration device is consistent with the surrounding first cabinet body 10 and second cabinet body 11 in appearance.

[0142] When the box door 1 opens the storage compartment, the box door 1 is in an open state, and 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 9 of the refrigeration device. For example, the side walls of the cabinet door 2 and the box door 1 are misaligned and form a gap that can accommodate the side of the first cabinet body 10 or the second cabinet body 11, so as to avoid collision or interference between the cabinet door 2 and the first cabinet body 10 or the second cabinet body 11 caused by the opening of the box door 1.

[0143] 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 by the scope of the claims of the present invention.
