[0071] The following Figures 1 to 11 , 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.

[0072] In the first aspect, as Figure 1As shown in the figure, an embodiment of the present utility model provides 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. The sliding door mechanism includes a guiding member 3, a sliding member 4, an elastic member 7, a cam assembly 5 and a driving member 6. The guiding member 3 is configured to be arranged on the box door 1; the sliding member 4 is configured to be arranged on the cabinet door 2, and the sliding member 4 is movably arranged on the guiding member 3 along the width direction of the box door 1; the elastic member 7 is arranged between the guiding member 3 and the sliding member 4; the cam assembly 5 is rotatably arranged on the guiding member 3, and the cam assembly 5 is in movable contact with the sliding member 4; the driving member 6 is arranged on the box body 9 and is rotatably connected to the cam assembly 5. The driving member 6 is adapted to drive the cam assembly 5 to rotate during the opening process of the box door 1, and then the cam assembly 5 drives the sliding member 4 to drive the cabinet door 2 to move forward along the width direction; the elastic member 7 is adapted to drive the sliding member 4 to drive the cabinet door 2 to move backward along the width direction during the closing process of the box door 1.

[0073] In the embodiment of the present utility model, as Figure 4 shown, the box body 9 is provided with a hinge 10. An articulated shaft is arranged on the hinge 10, and the box door 1 is rotatably arranged on the articulated shaft to realize the opening or closing of the box door 1 relative to the box body 9.

[0074] Optionally, the relative movement between the guiding member 3 and the sliding member 4 can be realized by the sliding fit of a guiding rail and a guiding groove, or by the rolling of a pulley along a sliding groove 32.

[0075] During the opening process of the box door 1, the cam assembly 5 rotates forward under the driving action of the driving member 6. The cam assembly 5 abuts against the sliding member 4, causing the sliding member 4 to move forward along the positive width direction of the box door 1. At this time, the elastic member 7 is compressed to generate elastic potential energy; during the closing process of the box door 1, the cam assembly 5 rotates backward under the driving action of the driving member 6. At this time, the sliding member 4 moves backward along the width direction under the driving of the elastic potential energy of the elastic member 7.

[0076] Specifically, the positive direction can be towards the direction close to the hinge 10. At this time, the negative direction is towards the direction away from the hinge 10.

[0077] Specifically, the elastic member 7 can be an elastic sheet, an elastic block, or a spring.

[0078] Specifically, the driving member 6 can be a crank mechanism or a connecting rod assembly.

[0079] In this application, a guiding member 3 is provided on the cabinet door 1, a sliding member 4 is provided on the cabinet door 2, the sliding member 4 is movably arranged on the guiding member 3 along the width direction of the cabinet door 1, and an elastic member 7 is arranged between the guiding member 3 and the sliding member 4. Driven by the driving member 6 on the cam assembly 5, the cam assembly 5 drives the sliding member 4 to move forward in the positive direction of the width direction, and the elastic member 7 drives the sliding member 4 to move backward in the width direction. When the cabinet door 1 is opened, the driving member 6 drives the cam assembly 5 to rotate, and the cam assembly 5 abuts and cooperates with the sliding member 4, so that the sliding member 4 moves away from the hinge 10, thereby driving the cabinet door 2 to move 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 body. At the same time, the elastic member 7 is compressed along the direction away from the hinge 10, and elastic potential energy is stored in the elastic member 7. When the cabinet door 1 is closed, the driving member 6 drives the cam assembly 5 to rotate in the reverse direction, and the cam assembly 5 no longer applies a positive pressure to the sliding member 4. The sliding member 4 moves toward the hinge 10 under the driving of the elastic potential energy of the elastic member 7, thereby driving the cabinet door 2 to move toward 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 cabinet body around the refrigeration equipment.

[0080] Furthermore, the door body assembly of the present utility model rotatably connects the cabinet door 1 to the cabinet body 9, and uses a 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 cabinet door 1 can avoid the side cabinet body, avoiding interference between the cabinet door 2 and the surrounding cabinet bodies. Moreover, when the cabinet door 1 is closed, the cabinet door 1 and the cabinet door 2 are flush, which has aesthetic properties.

[0081] In some embodiments, as Figure 1 shown, an abutting convex portion 46 is provided at one end of the sliding member 4 facing the cam assembly 5, and an annular abutting surface 51 is provided on the outer circumferential side of the cam assembly 5. The abutting convex portion 46 is movably abutted against the annular abutting surface 51.

[0082] It can be understood that, as Figure 1 shown, an abutting convex portion 46 is provided at one end of the sliding member 4 that cooperates with the cam assembly 5. The provision of the abutting convex portion 46 provides good stability and reliability for the movable abutment between the sliding member 4 and the cam assembly 5. Among them, an arc-shaped abutting surface can be provided on the abutting convex portion 46, and an annular abutting surface 51 is provided on the outer circumferential side of the cam assembly 5. The formation of the annular abutting surface 51 can be set according to the displacement characteristics of the sliding member 4, such as a water droplet shape or an oval shape, etc., and no special limitation is made here, as long as the abutting convex portion 46 can drive the sliding member 4 to move along the width direction of the cabinet door 1 when moving and abutting along the annular abutting surface 51.

[0083] In some embodiments, the cam assembly 5 has a first rotation center 52 and a second rotation center 53. The cam assembly 5 is rotatably connected to the guide member 3 by arranging a rotating shaft at the first rotation center 52, and the cam assembly 5 is rotatably connected to the driving member 6 by arranging a rotating shaft at the second rotation center 53. The driving member 6 is adapted to drive the second rotation center 53 to rotate around the first rotation center 52.

[0084] It can be understood that in this embodiment, the cam assembly 5 is connected between the guide member 3 and the driving member 6. The cam assembly 5 has a first rotation center 52 and a second rotation center 53. Among them, the first rotation center 52 is the center point where the cam assembly 5 is rotatably connected to the guide member 3. By arranging a rotating shaft at the first rotation center 52, the cam assembly 5 can perform a rotational motion relative to the guide member 3. The second rotation center 53 is different from the first rotation center 52. The second rotation center 53 is the center point where the cam assembly 5 is rotatably connected to the driving member 6. The driving member 6 can drive the cam assembly 5 to rotate around the first rotation center 52 by arranging a rotating shaft at the second rotation center 53. In this way, under the drive of the driving member 6, the cam assembly 5 rotates, so as to change the abutting path between the sliding member 4 and the cam assembly 5, and further realize the movement of the sliding member 4 in the width direction.

[0085] In some embodiments, as Figure 1 shown, the driving member 6 includes a linkage. The first end of the linkage is configured to be rotatably arranged at a fixed position on the box body 9, and the second end of the linkage is rotatably connected to the second rotation center 53 of the cam assembly 5 through a rotating shaft; the fixed position is arranged deviating from the hinge position between the box door 1 and the box body 9;

[0086] During the process of the box door 1 opening the box body 9, the linkage drives the sliding member 4 to move toward the side away from the hinge position through the cam assembly 5;

[0087] During the process of the box door 1 closing the box body 9, the elastic member 7 drives the sliding member 4 to move toward the side close to the hinge position.

[0088] It can be understood that the first end of the linkage in this embodiment is rotatably arranged on the hinge 10. When the box door 1 rotates relative to the box body 9 around the hinge axis, the second end of the linkage rotates in a circular motion with the hinge axis as the center. Since the first end of the linkage is arranged in a dislocation manner with the hinge axis, the distance between the second end of the linkage and the hinge 10 will change with the rotation of the linkage, so that the cam assembly 5 can be actuated to rotate, and further drive the sliding member 4 in abutting cooperation with the cam assembly 5 to move along the width direction of the box door 1 toward or away from the hinge 10.

[0089] The outer circular side of the cam assembly 5 abuts and cooperates with the sliding member 4 based on its specific rule. During the forward or reverse rotation of the cam assembly 5, the cam assembly 5 and the sliding member 4 will have intermittent abutting and cooperation, so that the sliding member 4 can move along the width direction of the door 1.

[0090] During the process of the door 1 opening the box body 9, as the door 1 rotates, the door 1 drives the linkage to rotate. The second end of the linkage rotates towards the side away from the box body 9. The second end of the linkage drives the cam assembly 5 to rotate. Since the cam assembly 5 applies a abutting force to the sliding member 4 during the rotation process of the cam assembly 5, the sliding member 4 moves along the width direction towards the side away from the hinge position, and further drives the cabinet door 2 to move towards the side away from the hinge position. At the same time, the elastic member 7 is compressed along the direction away from the hinge position to generate elastic potential energy.

[0091] During the process of the door 1 closing the box body 9, as the door 1 rotates, the door 1 drives the linkage to rotate. The second end of the linkage rotates towards the side close to the box body 9. The cam assembly 5 drives to rotate in reverse, so that the circumferential radius of the cam assembly 5 abutting against the sliding member 4 changes, and the abutting force applied by the cam assembly 5 on the sliding member 4 becomes smaller. At this time, the elastic member 7 moves towards the direction close to the hinge position under the drive of the elastic potential energy, and further drives the sliding member 4 to move along the width direction towards the side close to the hinge position, and further drives the cabinet door 2 to move towards the side close to the hinge position.

[0092] In this embodiment, by setting the first end of the linkage to deviate from the hinge position between the door 1 and the box body 9, the second end of the linkage can drive the cam assembly 5 to rotate, and further drive the sliding member 4 that abuts and cooperates with the cam assembly 5 to move along the width direction of the door 1. Moreover, the elastic member 7 can store elastic potential energy when the door 1 is opened, and drive the sliding member 4 to drive the cabinet door 2 to reset when the door 1 is closed. Using the elastic member 7 can realize the movement of the cabinet door 2 relative to the width direction of the door 1, and the structure is simple and easy to implement.

[0093] In some embodiments, as Figure 2 shown, the guide member 3 includes a fixing plate 31 and a sliding groove 32.

[0094] The fixing plate 31 is configured to be provided on the door 1.

[0095] The sliding groove 32 is provided on the fixing plate 31 and extends along the width direction. At least part of the sliding member 4 is movably provided in the sliding groove 32 along the width direction.

[0096] It can be understood that the fixing plate 31 of this embodiment is used to be fixedly connected to the door 1, and the sliding groove 32 is used to guide the movement of the sliding member 4 along the width direction of the door 1. Based on the sliding cooperation between the sliding member 4 and the sliding groove 32, it is ensured that the sliding member 4 can move stably and reliably along the width direction of the door 1.

[0097] In some embodiments, as Figure 1 and Figure 2 shown, the guide member 3 further includes a sliding sleeve 33, and the sliding sleeve 33 is disposed at one end of the chute 32 away from the hinge position.

[0098] The sliding member 4 includes a guide rod 41 and a slider 42. The guide rod 41 passes through the sliding sleeve 33, and a sliding contact 45 is provided on the guide rod 41. The sliding contact 45 is movably disposed in the chute 32 in the width direction; the slider 42 is connected to the guide rod 41 and is configured to be connected to the cabinet door 2.

[0099] Wherein, the elastic member 7 is disposed between the sliding sleeve 33 and the sliding contact 45.

[0100] It can be understood that the chute 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 chute 32. And as the sliding member 4 moves on the chute 32, the sliding contact 45 also moves accordingly. The sliding sleeve 33 is fixedly disposed relative to the fixing plate 31. The elastic member 7 is limited between the sliding sleeve 33 and the sliding contact 45. When the guide rod 41 moves toward the side away from the hinge 10, the sliding contact 45 moves toward 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 toward the side close to the hinge 10, the elastic member 7 releases elastic potential energy and elongates, and the sliding contact 45 moves toward 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.

[0101] And 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 in the width direction of the cabinet door 1, the sliding can drive the cabinet door 2 to move in the width direction of the cabinet door 1.

[0102] In some embodiments, as shown in the figure and the figure, the elastic member 7 includes a spring. The spring is sleeved outside the guide rod 41 and is limited between the sliding sleeve 33 and the sliding contact 45.

[0103] It can be understood that when the elastic member 7 is set 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 compression and elongation of the spring changes. And 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 stopping of both ends when the spring is compressed and elongated. The spring in this embodiment makes the structure simple and compact when the cabinet door 2 is reset relative to the cabinet door 1, with a small volume and saving the installation space of the cabinet door 2.

[0104] In some embodiments, as Figure 3As shown, the sliding member 4 further includes a first connecting arm 43 and a second connecting arm 44.

[0105] The first connecting arm 43 and the second connecting arm 44 are arranged at intervals in the width direction. The first end of the guide rod 41 is connected to the first end of the slider 42 through the first connecting arm 43, and the second end of the guide rod 41 is connected to the second end of the slider 42 through the second connecting arm 44.

[0106] The sliding sleeve 33 and the sliding contact 45 are located between the first connecting arm 43 and the second connecting arm 44.

[0107] It can be understood that the first connecting arm 43 and the second connecting arm 44 connect the guide rod 41 and the slider 42 respectively from both ends of the guide rod 41 and the slider 42, making the connection between the guide 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.

[0108] Further, the slider 42 of this embodiment is arranged perpendicular to 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 fitted, 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.

[0109] In some embodiments, as Figures 5 to 10 shown, the sliding door mechanism further includes a sliding module 8.

[0110] The sliding module 8 is configured to be arranged between the cabinet door 1 and the cabinet door 2, and the sliding module 8 is used to guide the cabinet door 2 to move relative to the cabinet door 1 along the width direction.

[0111] 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 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.

[0112] 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 matched in the width direction. The first sliding member 82 can be installed on the cabinet door 1 and the second sliding member 82 can be installed on the cabinet door 2, or the first sliding member 82 can be installed on the cabinet door 2 and the second sliding member 82 can be installed on the cabinet door 1. The sliding module 8 realizes the relative movement between the cabinet door 1 and the cabinet door 2 through the relative sliding of the first sliding member 82 and the second sliding member 82.

[0113] In some embodiments, as Figure 6 and Figure 7 shown, the sliding module 8 includes a slide rail 81 and a moving member.

[0114] The slide rail 81 is configured to be provided on the door 1 and extend along the width direction.

[0115] The moving member is movably provided on the slide rail 81 along the width direction, and the moving member is configured to be detachably connected to the cabinet door 2.

[0116] It can be understood that the slide rail 81 can be in the structural form of a chute 32, and the moving member is correspondingly in the structural form of sliding along the chute 32; the slide rail 81 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 81 and moving.

[0117] The moving member can move along the extending direction of the slide rail 81. Based on the guiding and supporting functions 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 cabinet door 2 can move stably and reliably along the width direction of the door 1.

[0118] 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.

[0119] 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.

[0120] In some embodiments, as Figure 5 shown, there are at least two sets of sliding modules 8. The cam assembly 5 is rotatably connected to the driving member 6. The cam assembly 5 is in movable abutting contact with the sliding member 4. The elastic member 7 is provided between the guiding member 3 and 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.

[0121] Wherein, the cam assembly 5 and the elastic member 7 are used to drive the sliding member 4 to drive the moving member to move along the slide rail 81.

[0122] 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 cam assembly 5 to drive the moving member to move along the slide rail 81, and further enable the driving member 6 to control the cam 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.

[0123] 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, one set of the two sets of sliding modules 8 located at the upper end and 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 among the four sets of sliding modules 8 are arranged in parallel.

[0124] 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.

[0125] In some embodiments, as Figure 6 and Figure 7 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.

[0126] 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.

[0127] Furthermore, the slider 82 of this embodiment includes a sliding body 821 and an adapter seat 822. The sliding body 821 and the adapter seat 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 on the slide rail 81 in the width direction. A first card slot 8221 is provided on the adapter seat 822 for hanging 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 part. 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.

[0128] In some embodiments, as Figures 6 to 10 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 arranged on the fixed seat 831 in the vertical direction or the horizontal direction, and the hanging part 832 is hung on the slider 82.

[0129] It can be understood that a small amount of adjustment in the vertical direction or the horizontal direction can be achieved between the hanging part 832 and the fixed seat 831, 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 832 and the fixed seat 831, so that the box door 1 and the cabinet door 2 can correct slight deviations in installation or manufacturing through fine adjustment, ensuring the aesthetics of the installation of the box door 1 and the cabinet door 2.

[0130] 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 box 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.

[0131] 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.

[0132] like Figure 9 and Figure 10 As shown, the process of installing the hanging member 83 and the cabinet door 2 is as follows:

[0133] 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.

[0134] In the second aspect, Figure 4 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 of the refrigeration device 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.

[0135] 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.

[0136] Specifically, since the door body assembly includes a sliding door mechanism, and the specific structure of the sliding door mechanism refers to the above embodiments, the door body assembly shown in this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0137] 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 cabinet door 2 to move relative to the cabinet door 1.

[0138] 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 use requirements of users in different scenarios.

[0139] 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.

[0140] 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.

[0141] In the third aspect, as Figure 4 and Figure 11 shown, the embodiment of the present utility model also provides a refrigeration equipment, including: a cabinet body 9 and the above 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.

[0142] Specifically, since the refrigeration equipment includes a door body assembly, and the specific structure of the door body assembly refers to the above embodiments, the refrigeration equipment shown in this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0143] It is understandable that the box door 1 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 of the refrigeration equipment with 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.

[0144] 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, interference between the cabinet door 2 and the cabinet bodies around the refrigeration equipment can be avoided, 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.

[0145] In some embodiments, as Figure 4 shown, the box body 9 is configured to be disposed in the accommodation space between the first cabinet body 11 and the second cabinet body 12.

[0146] 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.

[0147] 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.

[0148] 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 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 use convenience 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.

[0149] In some embodiments, as Figure 4 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.

[0150] 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 disposed close to the hinge 10.

[0151] When the cabinet door 2 is in the second position, the cabinet door 1 opens the storage room, 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.

[0152] It can be understood that the storage room is used to store items to be refrigerated or frozen. When the cabinet door 1 closes the storage room, the cabinet 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 cabinet door 1 are flush. At this time, the cabinet door 2 can completely cover the cabinet 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.

[0153] When the cabinet door 1 opens the storage room, the cabinet 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 wall of the cabinet door 2 and the side wall of the cabinet 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 cabinet door 1.

[0154] 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.
