[0078] The following combines Figures 1 to 14 , and through specific embodiments and their application scenarios, the sliding door mechanism, door body assembly, and refrigeration device provided by the embodiments of the present utility model are described in detail.

[0079] In the first aspect, as Figure 1 and Figure 4 shown, the embodiments of the present utility model provide a sliding door mechanism, which is applied to a refrigeration device. The refrigeration device includes a box body 9 and a box door 1. The box door 1 is rotatably arranged on the box body 9 and includes: a guiding member 3, a sliding member 4, a connecting rod assembly 5, and a driving member 6.

[0080] The guiding member 3 is configured to be arranged on the box door 1 of the refrigeration device, and the sliding member 4 is configured to be arranged on the cabinet door 2. The sliding member 4 is movably arranged on the guiding member 3 along the width direction of the box door 1.

[0081] The connecting rod assembly 5 is rotatably arranged on the guiding member 3, and the second end of the connecting rod assembly 5 is movably connected to the sliding member 4.

[0082] The driving member 6 is arranged on the box body 9 and is movably connected to the first end of the connecting rod assembly 5 to drive at least a part of the connecting rod assembly 5 to rotate relative to the guiding member 3 during the opening and closing process of the box door 1.

[0083] Wherein, the sliding member 4 is used to drive the cabinet door 2 to move along the width direction under the transmission of the connecting rod assembly 5.

[0084] It can be understood that, as Figure 7 shown, the box body 9 is provided with a hinge 10, and an articulated shaft is arranged on the hinge 10. 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 9.

[0085] By the rotation of the connecting rod assembly 5 relative to the guiding member 3, the distance between the second end of the connecting rod assembly 5 and the hinge 10 is changed, and further the distance between the sliding member 4 and the hinge 10 is changed, and further the distance between the cabinet door 2 connected to the sliding member 4 and the hinge 10 is changed.

[0086] Optionally, the link assembly 5 can be a parallelogram linkage or a crank-rocker mechanism.

[0087] For the sliding door mechanism shown in this embodiment, by arranging the guide member 3 on the cabinet door 1, the sliding member 4 on the cabinet door 2, the sliding member 4 is movably arranged on the guide member 3 along the width direction of the cabinet door 1, the link assembly 5 is rotatably arranged on the guide member 3, and the second end of the link assembly 5 is movably connected to the sliding member 4. When the cabinet door 1 is opened, the driving member 6 drives the first end of the link assembly 5, thereby driving part of the link assembly 5 to rotate relative to the guide member 3. The second end of the link assembly 5 pulls the sliding member 4 to move in a direction away from the hinge 10, thereby driving the cabinet door 2 to move in a direction away from the hinge 10 along the width direction of the cabinet door 1, so that the cabinet door 2 does not interfere with the side cabinet; when the cabinet door 1 is closed, the driving member 6 drives the first end of the link assembly 5, thereby driving part of the link assembly 5 to rotate relative to the guide member 3. The second end of the link assembly 5 pulls the sliding member 4 to move in a direction close to the hinge 10, thereby driving the cabinet door 2 to move in a direction close to the hinge 10 along 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 cabinets around the refrigeration equipment.

[0088] In some embodiments, as Figure 1 and Figure 4 shown, the link assembly 5 includes: a first link 51 and a second link 52.

[0089] The middle part of the first link 51 is rotatably arranged on the guide member 3, and the first end of the first link 51 is movably connected to the driving member 6.

[0090] The first end of the second link 52 is movably connected to the second end of the first link 51, and the second end of the second link 52 is movably connected to the sliding member 4.

[0091] Wherein, the driving member 6 is used to drive the first link 51 to rotate relative to the guide member 3 to change the included angle between the first link 51 and the second link 52, and then drive the sliding member 4 to move relative to the guide member 3 by the second link 52.

[0092] It can be understood that the driving member 6 provides a driving force to the first end of the first link 51. In this embodiment, a hinge shaft is arranged in the middle of the first link 51, the hinge shaft is installed on the guide member 3, and the middle part of the first link 51 rotates around the guide member 3 through the hinge shaft, thereby changing the included angle between the first link 51 and the second link 52, so that the second link 52 moves along the width direction.

[0093] During the process of opening the cabinet door 1 to open the cabinet body 9, the driving member 6 drives the first end of the first link 51 to move in the width direction towards the hinge 10. The first link 51 rotates clockwise around the middle, the included angle between the first link 51 and the second link 52 becomes larger, pushing the second link 52 to move away from the hinge 10, and then driving the sliding member 4 to move in the width direction away from the hinge 10, so that the cabinet door 2 does not interfere with the side cabinet body.

[0094] During the process of closing the cabinet door 1 to close the cabinet body 9, the driving member 6 drives the first end of the first link 51 to move in the width direction away from the hinge 10. The first link 51 rotates counterclockwise around the middle, the included angle between the first link 51 and the second link 52 becomes smaller, pushing the second link 52 to move towards the hinge 10, and then driving the sliding member 4 to move in the width direction towards the hinge 10, so that the cabinet door 2 returns to its original position, ensuring that the cabinet door 2 does not interfere with the cabinet body around the refrigeration equipment.

[0095] In this embodiment, by providing the first link 51 and the second link 52 in the link assembly 5, and by the rotation of the middle part of the first link 51 around the guide member 3, the included angle between the first link 51 and the second link 52 is changed, so that the second link 52 can drive the sliding member 4 to move in the width direction, realizing the movement of the cabinet door 2 relative to the cabinet door 1, with a simple structure and a small volume.

[0096] In some embodiments, as Figure 1 and Figure 4 shown, the driving member 6 includes: a linkage member.

[0097] The first end of the linkage member is configured to be rotatably disposed at a fixed position on the cabinet body 9 of the refrigeration equipment, and the second end of the linkage member is rotatably connected to the first end of the first link 51; the fixed position is arranged deviating from the hinge position between the cabinet door 1 and the cabinet body 9.

[0098] During the process of opening the cabinet door 1 to open the cabinet body 9, the linkage member drives the first link 51 to rotate in the first rotation direction to control the increase of the included angle between the first link 51 and the second link 52, and the second link 52 drives the sliding member 4 to drive the cabinet door 2 to move towards the side away from the hinge position.

[0099] During the process of closing the cabinet door 1 to close the cabinet body 9, the linkage member drives the first link 51 to rotate in the second rotation direction to control the decrease of the included angle between the first link 51 and the second link 52, and the second link 52 drives the sliding member 4 to drive the cabinet door 2 to move towards the side close to the hinge position.

[0100] It is understandable that the first end of the linkage member in this embodiment is rotatably provided on the hinge 10. When the door 1 rotates relative to the box body 9 around the hinge axis, the second end of the linkage member rotates in a circular motion with the hinge axis as the center. Since the first end of the linkage member is misaligned with the hinge axis, the distance between the second end of the linkage member and the hinge 10 will change as the linkage member rotates, thereby driving the link assembly 5 to move along the width direction of the door 1 towards or away from the hinge 10.

[0101] During the process of the door 1 opening the box body 9, as the door 1 rotates, the door 1 drives the linkage member to rotate. The second end of the linkage member drives the first end of the first link 51 to move towards the side close to the hinge position. The first link 51 rotates clockwise around its middle part, and the included angle between the first link 51 and the second link 52 becomes larger. The second end of the second link 52 drives the sliding member 4 to move towards the side away from the hinge position, thereby causing the cabinet door 2 to move towards the side away from the hinge position.

[0102] During the process of the door 1 closing the box body 9, as the door 1 rotates, the door 1 drives the linkage member to rotate. The second end of the linkage member drives the first end of the first link 51 to move towards the side away from the hinge position. The first link 51 rotates counterclockwise around its middle part, and the included angle between the first link 51 and the second link 52 becomes smaller. The second end of the second link 52 drives the sliding member 4 to move towards the side away from the hinge position, thereby causing the cabinet door 2 to move towards the side close to the hinge position.

[0103] In this embodiment, by arranging the first end of the linkage member to deviate from the hinge position between the door 1 and the box body 9, the second end of the linkage member can drive the first end of the first link 51, enabling the first link 51 to rotate around its middle part. By changing the included angle between the first link 51 and the second link 52, the second link 52 can drive the sliding member 4 to move along the width direction. The opening and closing of the door 1 can control the transmission of the linkage member driving the link assembly 5, enabling the sliding member 4 to drive the cabinet door 2 to move along the width direction without an additional driving device, and the movement of the cabinet door 2 relative to the door 1 can be synchronized with the opening and closing of the door 1.

[0104] In some embodiments, as Figure 2 and Figure 3 shown, the guiding member 3 includes: a fixing plate 31 and a sliding sleeve 33; the fixing plate 31 is configured to be provided on the door 1; the sliding sleeve 33 is provided on the fixing plate 31 and extends along the width direction.

[0105] The sliding member 4 includes a guiding rod 41 and a slider 42. The guiding rod 41 passes through the sliding sleeve 33 and is movably connected to the second end of the link assembly 5; the slider 42 is connected to the guiding rod 41 and is configured to be connected to the cabinet door 2.

[0106] It is understandable that the fixing plate 31 in this embodiment is used for fixedly connecting with the cabinet door 1. The length of the sliding sleeve 33 in this embodiment is about half of the length of the guiding rod 41. Based on the sliding guidance and limitation of the guiding rod 41 by the sliding sleeve 33, the guiding rod 41 can stably move along the width direction.

[0107] In some embodiments, as Figure 2 and Figure 3 shown, the sliding member 4 further includes: a first connecting arm 43 and a second connecting arm 44.

[0108] The first connecting arm 43 and the second connecting arm 44 are arranged at intervals along the width direction. The first end of the guiding rod 41 is connected to the first end of the slider 42 through the first connecting arm 43, and the second end of the guiding rod 41 is connected to the second end of the slider 42 through the second connecting arm 44.

[0109] Among them, the sliding sleeve 33 is located between the first connecting arm 43 and the second connecting arm 44.

[0110] It is understandable that the first connecting arm 43 and the second connecting arm 44 connect the guiding rod 41 and the slider 42 respectively from both ends of the guiding rod 41 and the slider 42, making the connection between the guiding rod 41 and the slider 42 relatively firm. And when the slider 42 moves along the width direction of the cabinet door 1, it is easier to fit along the width direction.

[0111] Furthermore, the slider 42 in this embodiment is perpendicularly arranged with the first connecting arm 43 and the second connecting arm 44. When the cabinet door 2 is installed on the slider 42, the fixing plate 31 is installed at the top of the cabinet door 1, and the cabinet door 2 and the cabinet door 1 can be parallel and fit, ensuring the flatness of the cabinet door 2 installed on the cabinet door 1. And it is beneficial for the cabinet door 2 to move along the cabinet door 1.

[0112] In some embodiments, as Figure 4 , Figure 5 and Figure 6 shown, the sliding door mechanism further includes: an elastic member 7.

[0113] The elastic member 7 is arranged between the guiding member 3 and the sliding member 4.

[0114] When the link assembly 5 drives the sliding member 4 to move towards the side away from the hinge position between the cabinet door 1 and the cabinet body 9, the sliding member 4 compresses the elastic member 7 during the process of driving the cabinet door 2 to move.

[0115] When the link assembly 5 drives the sliding member 4 to move towards the side close to the hinge position, the elastic member 7 drives the sliding member 4 to drive the cabinet door 2 to move towards the hinge position.

[0116] It is understandable that when the link assembly 5 drives the sliding member 4 to move towards the side away from the hinge position, the elastic member 7 is squeezed along the direction away from the hinge 10 and stores elastic potential energy.

[0117] When the connecting rod assembly 5 drives the sliding member 4 to move towards the side close to the hinge position, the elastic potential energy of the elastic member 7 is released, and the elastic force of the elastic member 7 acts on the sliding member 4 to drive the sliding member 4 close to the hinge position.

[0118] Specifically, the elastic member 7 can be an elastic sheet, an elastic block, or a spring.

[0119] In this embodiment, by arranging the elastic member 7 in the sliding door mechanism, based on the elastic deformation of the elastic member 7, it can ensure that the movement of the sliding member 4 relative to the guiding member 3 is more stable and reliable.

[0120] In some embodiments, as Figure 5 shown, the guiding member 3 includes: a fixing plate 31 and a sliding groove 32.

[0121] The fixing plate 31 is configured to be provided on the cabinet door 1.

[0122] The sliding groove 32 is provided on the fixing plate 31 and extends along the width direction, and at least part of the sliding member 4 is movably provided in the sliding groove 32 along the width direction.

[0123] It can be understood that the fixing plate 31 of this embodiment is used for fixedly connecting with the cabinet door 1, and the sliding groove 32 is used for guiding the movement of the sliding member 4 along the width direction of the cabinet door 1. Based on the sliding fit between the sliding member 4 and the sliding groove 32, it can ensure that the sliding member 4 can move stably and reliably along the width direction of the cabinet door 1.

[0124] In some embodiments, as Figure 5 shown, the guiding member 3 further includes a sliding sleeve 33, and the sliding sleeve 33 is provided at one end of the sliding groove 32 away from the hinge position.

[0125] The sliding member 4 includes a guiding rod 41 and a slider 42. The guiding rod 41 passes through the sliding sleeve 33, and a sliding contact 45 is provided on the guiding rod 41. The sliding contact 45 is movably provided in the sliding groove 32 along the width direction; the slider 42 is connected to the guiding rod 41 and is configured to be connected with the cabinet door 2.

[0126] Wherein, the elastic member 7 is provided between the sliding sleeve 33 and the sliding contact 45.

[0127] It is understandable that the sliding groove 32 in this embodiment is arc-shaped to be adapted to the outer wall of the guide rod 41. The sliding sleeve 33 is used to guide the movement of the guide rod 41 relative to the sliding groove 32. Moreover, as the sliding member 4 moves on the sliding groove 32, the sliding contact 45 also moves accordingly. The sliding sleeve 33 is fixedly arranged relative to the fixed plate 31. The elastic member 7 is limited between the sliding sleeve 33 and the sliding contact 45. When the guide rod 41 moves towards the side away from the hinge 10, the sliding contact 45 moves towards the sliding sleeve 33, causing the elastic member 7 between the sliding sleeve 33 and the sliding contact 45 to be compressed. When the guide rod 41 moves towards the side close to the hinge 10, the elastic member 7 releases elastic potential energy and elongates, and the sliding contact 45 moves towards the direction away from the sliding sleeve 33. The sliding sleeve 33 and the sliding contact 45 constrain the elastic member 7 from both sides of the elastic member 7 to ensure the reliability of the compression and elongation of the elastic member 7.

[0128] Moreover, one end of the slider 42 is connected to the guide rod 41, and the other end is connected to the cabinet door 2, so that when the guide rod 41 moves along the width direction of the cabinet door 1, the sliding can drive the cabinet door 2 to move along the width direction of the cabinet door 1.

[0129] In some embodiments, as Figure 4 shown, the elastic member 7 includes a spring. The spring is sleeved on the outer side of the guide rod 41 and is limited between the sliding sleeve 33 and the sliding contact 45.

[0130] It is understandable that when the elastic member 7 is arranged as a spring, the hollow structure of the spring enables the spring to be sleeved on the outer wall of the guide rod 41. And in the length direction of the guide rod 41, the state of the spring changes in terms of compression and elongation. Moreover, the sliding sleeve 33 and the sliding contact 45 can limit both sides of the spring from both ends of the guide rod 41, facilitating the stop at both ends when the spring compresses and elongates. The spring in this embodiment makes the structure simple and compact when the cabinet door 2 is reset relative to the cabinet body 1, with a small volume and saving the installation space of the cabinet door 2.

[0131] In some embodiments, as Figures 8 to 13 shown, the sliding door mechanism further includes: a sliding module 8.

[0132] The sliding module 8 is configured to be arranged between the cabinet door 1 and the cabinet door 2. The sliding module 8 is used to guide the cabinet door 2 to move relative to the cabinet door 1 along the width direction.

[0133] 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 8 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.

[0134] The sliding module 8 includes a first sliding member 82 and a second sliding member 82. The first sliding member 82 and the second sliding member 82 are slidably engaged in the width direction. The first sliding member 82 can be mounted on the cabinet door 1, and the second sliding member 82 can be mounted on the door 2. Alternatively, the first sliding member 82 can be mounted on the door 2, and the second sliding member 82 can be mounted on the cabinet door 1. The sliding module 8 realizes the relative movement of the cabinet door 1 and the door 2 through the relative sliding of the first sliding member 82 and the second sliding member 82.

[0135] In some embodiments, as Figure 9 and Figure 10 shown, the sliding module 8 includes: a slide rail 81 and a moving member.

[0136] The slide rail 81 is configured to be disposed on the cabinet door 1 and extend in the width direction.

[0137] The moving member is movably disposed on the slide rail 81 in the width direction and is configured to be detachably connected to the door 2.

[0138] It can be understood that the slide rail 81 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 81 can also be in the form of a slide bar structure; the moving member is correspondingly in the form of a structure that wraps the slide rail and moves.

[0139] The moving member can move along the extension direction of the slide rail 81. Based on the guiding and supporting effects of the slide rail 81, the moving member can move stably and reliably along the slide rail 81. Moreover, based on the high rigidity of the slide rail 81, 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.

[0140] 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.

[0141] 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.

[0142] In some embodiments, as Figure 8 shown, at least two sets of sliding modules 8 are provided. The first end of the link assembly 5 is connected to the driving member 6, and the second end of the link assembly 5 is connected to the sliding member 4. The sliding member 4 is connected to the moving member of one of the at least two sets of sliding modules 8.

[0143] Among them, the link assembly 5 is used to drive the sliding member 4 to drive the moving member to move along the slide rail 81.

[0144] It is understandable that multiple sets of sliding modules 8 can be provided. One set of the sliding modules 8 is used to connect with the sliding member 4, so that the driving member 6 can control the link assembly 5 to drive the moving member to move along the slide rail 81. Furthermore, the driving assembly can control the link assembly 5 to drive the cabinet door 2 to move relative to the box door 1 along the extension direction of the slide rail 81. The sliding module 8 connected to the sliding member 4 serves as an active driving mechanism, realizing the cooperative design of the driving member 6 and the sliding module 8. For cooperative guidance, the slide rails 81 in each sliding module 8 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 8 serve as passive guiding mechanisms. Through the cooperation of the multiple sets of sliding modules 8, 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.

[0145] Specifically, four sets of sliding modules 8 are provided in this embodiment. Two sets of the sliding modules 8 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 8 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, in the two sets of sliding modules 8 located at the upper end, one set close to the hinge 10 is connected to the sliding member 4, and the remaining three sets of sliding modules 8 are respectively arranged at the remaining triangles of the box door 1. The slide rails 81 in the four sets of sliding modules 8 are arranged in parallel.

[0146] Correspondingly, among the three sets of passive sliding modules 8, the sliding module 8 located at the upper end of the box door 1 has the same structure as the sliding module 8 located at the lower end of the box door 1 and is symmetrically arranged on the box door 1.

[0147] In some embodiments, as Figure 9 and Figure 10 shown, the moving member includes a sliding member 82 and a hanging member 83; the sliding member 82 is movably arranged along the width direction on the slide rail 81, and the hanging member 83 is configured to be connected to the cabinet door 2 and is hung on the sliding member 82.

[0148] It is understandable that the hanging member 83 is used to connect the sliding member 82 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 82. Moreover, the hanging member 83 is configured to be detachably connected to the cabinet door 2.

[0149] Further, the sliding member 82 of this embodiment includes a sliding body 821 and a adapter base 822. The sliding body 821 and the adapter base 822 are fixedly connected. A support frame 811 is provided on the slide rail 81. A round hole is provided on the support frame 811, and a ball is installed in the round hole. The sliding body 821 is in rolling contact with the slide rail 81 to move along the width direction on the slide rail 81. A first card slot 8221 is provided on the adapter base 822, and the first card slot 8221 is used to hang the hanging member 83 on the sliding body 821. The relative movement between the sliding body 821 and the slide rail 81 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 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 cabinet door 1.

[0150] Optionally, as Figure 9 shown, the sliding module 8 is an active driving mechanism. The sliding module 8 is connected to the sliding member 4, the sliding member 4 is connected to the link assembly 5, and the driving member 6 is connected to the link assembly 5, so that the driving member 6 can control the link assembly 5 to drive the movement of the sliding body 821.

[0151] In some embodiments, as Figures 9 to 13 shown, the hanging member 83 includes a fixed seat 831 and a hanging part 832; the fixed seat 831 is configured to be connected to the cabinet door 2, and the hanging part 832 is adjustably provided on the fixed seat 831 in the vertical or horizontal direction, and the hanging part 832 is hung on the sliding member 82.

[0152] It can be understood that a slight adjustment in the vertical or horizontal direction can be realized between the hanging part 832 and the fixed seat 831. Thus, by adjusting the relative position between the hanging part 832 and the fixed seat 831, the position deviation between the cabinet door 2 and the cabinet door 1 can be adjusted, so that the cabinet 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 cabinet door 1 and the cabinet door 2.

[0153] Specifically, the fixed seat 831 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 831 for accommodating the hanging part 832; the hanging part 832 is slidably arranged in the installation groove, and a first card joint 8321 is formed on the hanging part 832 to adjust the relative position between the cabinet door 2 and the cabinet door 1 by adjusting the position of the hanging part 832 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.

[0154] Specifically, the first clamping joint 8321 is a U-shaped hook facing downward, which can pass through the notch and slide into the first clamping groove 8221. The hanging member 832 is provided with a first rectangular hole extending in the up-down direction, the fixing seat 831 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 hanging member 832 can slide in the mounting groove. By controlling the position of the hanging member 832 in the mounting groove, the hanging member 832 can be moved up and down relative to the fixing seat 831. A screw can be provided to pass through the first rectangular hole on the mounting groove and the second rectangular hole on the hanging member 832, so as to form a hanging member 832 that can be adjusted in both the up-down and left-right directions. And through the relative position of the mounting hole of the fixing seat 831 and the cabinet door 2, the position of the fixing seat 831 and the cabinet door 2 can be adjusted in the up-down and left-right directions.

[0155] like Figure 12 and Figure 13 As shown, the process of installing the hanging member 83 and the cabinet door 2 is as follows:

[0156] The hanging piece 832 is inserted into the mounting groove of the fixing seat 831. The fixing seat 831 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 8321 on the connected hanging piece 832 is hung in the first clamping groove 8221 to complete the connection between the hanging piece 832 and the adapter 822. 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 83 is separated from the cabinet door 2, and the position of the hanging piece 83 is adjusted. The cabinet door 2 and the fixing seat 831, the hanging piece 832 assembly, adjust the position of the hanging piece 832. 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 831 and the cabinet door 2, and the cabinet door 2 and the fixing seat 831 are further fixed to keep its position stable. The above method can not only fine-tune the position of the fixing seat 831, 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.

[0157] In the second aspect, Figure 7 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 9 to open or close the storage compartment in the box body 9. The cabinet door 2 is arranged on the side of the box door 1 away from the box body 9 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.

[0158] 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.

[0159] 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.

[0160] 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.

[0161] For the door body assembly shown in this embodiment, by rotatably connecting the cabinet door 1 to the cabinet body 9, and 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 sliding door mechanism, the movement of the cabinet door 2 relative to the cabinet door 1 is controlled, so that the cabinet door 1 can avoid the side cabinet body during the opening and closing processes, thereby avoiding the interference between the cabinet door 2 and the outside when the cabinet door 1 rotates, and meeting the user's usage requirements in different scenarios.

[0162] 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.

[0163] 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.

[0164] In the third aspect, as Figure 7 and Figure 14 shown, the embodiment of the present utility model further provides a refrigeration equipment, including: a cabinet body 9 and the above-mentioned door body assembly. The cabinet body 9 has a storage compartment, and the cabinet door 1 is rotatably arranged on the cabinet body 9 to open or close the storage compartment.

[0165] 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.

[0166] It is understandable that the door 1 of the box is used to open and close the storage compartment. When the refrigeration equipment is installed in a fully built-in manner, in order to maintain the consistency between the refrigeration equipment and the surrounding cabinet bodies, a cabinet door 2 with the same material and color as the surrounding cabinet bodies is installed on the outer side of the box door 1.

[0167] The refrigeration equipment of this embodiment can install the cabinet door 2 on the box door 1 through a sliding door mechanism, so that when the refrigeration equipment is opened and closed, the interference between the cabinet door 2 and the surrounding cabinet bodies can be avoided, greatly improving the usability. Especially in a restricted kitchen environment, this design advantage is more obvious. In addition, the setting of the sliding door mechanism enables the cabinet door 2 to move smoothly during the opening and closing processes, improving the service life and stability of the refrigerator.

[0168] In some embodiments, as Figure 7 shown, the box body 9 is configured to be arranged in the accommodation space between the first cabinet body 11 and the second cabinet body 12.

[0169] During the opening or closing process of the box door 1, the driving member 6 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 body 11 or the second cabinet body 12.

[0170] It is understandable that an opening is provided on the outer side of the accommodation space between the first cabinet body 11 and the second cabinet body 12. This design enables the refrigeration equipment to be integrally embedded in the cabinet body. During the process of the box door 1 passing through the opening to control the opening or closing of the accommodation space, the driving member 6 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 9 so that the cabinet door 2 avoids the side walls of the first cabinet body 11 and the second cabinet body 12.

[0171] 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 6 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 9. This design is mainly to avoid the interference between the cabinet door 2 and the side walls of the first cabinet body 11 and the second cabinet body 12. 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 body. This design not only improves the usability 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.

[0172] In some embodiments, as Figure 7 shown, the box door 1 is rotatably connected to the box body 9 through a hinge 10; the cabinet door 2 can move relative to the box door 1 between a first position and a second position along the width direction.

[0173] 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 10 is arranged close to the hinge 10.

[0174] 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 10 is arranged away from the hinge 10 to avoid the side wall of the first cabinet body 11 or the second cabinet body 12.

[0175] 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 10 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 11 and second cabinet body 12 in appearance.

[0176] 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 10 of the refrigeration device. For example, the side walls of the cabinet door 2 and the box door 1 are misaligned, and a gap is formed that can accommodate the side of the first cabinet body 11 or the second cabinet body 12, so as to avoid collision or interference between the cabinet door 2 and the first cabinet body 11 or the second cabinet body 12 caused by the opening of the box door 1.

[0177] 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.
