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.

[0068] The following will be combined with Figures 1 to 11 , and the sliding door mechanism, door body assembly, and refrigeration equipment provided by the embodiments of the present utility model will be described in detail through specific embodiments and their application scenarios.

[0069] In the first aspect, as Figure 1 shown, the embodiments of the present utility model provide a sliding door mechanism applied to a refrigeration equipment. The refrigeration equipment includes a box body 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, an elastic member 5, a driving member 6, and a towing rope 7.

[0070] The guiding member 3 is configured to be arranged on the box door 1 of the refrigeration equipment. 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.

[0071] The elastic member 5 is arranged between the guiding member 3 and the sliding member 4.

[0072] The driving member 6 is arranged on the box body 9 and is connected to the first end of the towing rope 7. The second end of the towing rope 7 is connected to the sliding member 4.

[0073] Wherein, during the opening and closing process of the box door 1, the driving member 6 is used to control the towing rope 7 to drive the sliding member 4 to move towards the first direction, and the elastic member 5 is used to drive the sliding member 4 to move towards the second direction. Both the first direction and the second direction are along the width direction, and the first direction and the second direction are opposite to each other.

[0074] It can be understood that, as Figure 4 shown, a hinge 10 is installed on the box body 9. An articulated shaft is provided 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.

[0075] Optionally, the relative movement between the guiding member 3 and the sliding member 4 can be realized through the sliding fit of a guiding rail and a guiding groove, or can also be realized through the rolling of a pulley along a sliding groove 34.

[0076] When the traction rope 7 drives the sliding member 4 to move in the first direction under the driving action of the driving member 6, the elastic member 5 is compressed in the first direction to generate elastic potential energy. When the traction rope 7 is slack, the elastic member 5 moves in the second direction under the drive of the elastic potential energy, driving the sliding member 4 to move in the second direction.

[0077] Specifically, the first direction can be towards the direction close to the hinge 10. At this time, the second direction is towards the direction away from the hinge 10. Or, the first direction can also be towards the direction away from the hinge 10. At this time, the second direction is towards the direction close to the hinge 10.

[0078] When the traction rope 7 drives the sliding member 4 to move towards the direction close to the hinge 10, the elastic member 5 is used to drive the sliding member 4 to move towards the direction away from the hinge 10. Or, when the traction rope 7 drives the sliding member 4 to move towards the direction away from the hinge 10, the elastic member 5 is used to drive the sliding member 4 to move towards the direction close to the hinge 10.

[0079] Specifically, the elastic member 5 can be an elastic sheet, an elastic block, or a spring. The driving member 6 can be a crank mechanism or a connecting rod assembly.

[0080] For the sliding door mechanism shown in this embodiment, by arranging the guiding 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 guiding member 3 along the width direction of the cabinet door 1, and the elastic member 5 is arranged between the guiding member 3 and the sliding member 4. Under the drive of the driving member 6 on the traction rope 7, the traction rope 7 drives the sliding member 4 to move in the first direction, and the elastic member 5 drives the sliding member 4 to move in the second direction. The first direction and the second direction are opposite. When the cabinet door 1 is opened, the driving member 6 drives the first end of the traction rope 7, and the traction rope 7 drives the sliding member 4 to move towards the direction away from the hinge 10, thereby driving the cabinet door 2 to move towards the 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 body, and at the same time, the elastic member 5 is compressed along the direction away from the hinge 10, and elastic potential energy is stored in the elastic member 5. When the cabinet door 1 is closed, the driving member 6 no longer applies traction force to the traction rope 7, the traction rope 7 is slack, and the elastic member 5 moves towards the direction close to the hinge 10 under the drive of the elastic potential energy, driving the sliding member 4 to move towards the direction close to the hinge 10, thereby driving the cabinet door 2 to move towards the 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 cabinet body around the refrigeration equipment.

[0081] In some embodiments, as Figure 1 shown, the driving member 6 includes: a linkage member.

[0082] The first end of the linkage member is rotatably arranged at a fixed position on the box body 9, and the fixed position is arranged deviating from the hinge position between the cabinet door 1 and the box body 9.

[0083] The towing rope 7 is movably arranged on the guiding member 3. The first end of the towing rope 7 is connected to the second end of the linkage member, and the second end of the towing rope 7 is connected to the end of the sliding member 4 away from the hinge position.

[0084] During the process of the door 1 opening the box body 9, the linkage member drives the sliding member 4 to move toward the side away from the hinge position through the towing rope 7.

[0085] During the process of the door 1 closing the box body 9, the elastic member 5 drives the sliding member 4 to move toward the side close to the hinge position.

[0086] It can be understood that the first end of the linkage member in this embodiment is rotatably arranged 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 arranged offset from the hinge axis, the distance between the second end of the linkage member and the hinge 10 will change with the rotation of the linkage member, thereby driving the towing rope 7 to move along the width direction of the door 1 toward or away from the hinge 10.

[0087] The towing rope 7 is arranged on the guiding member 3 based on the rope-passing channel and the guiding structure for the towing rope 7, and moves along the width direction of the door 1 under the guidance of the rope-passing channel and the guiding structure.

[0088] Specifically, the rope-passing channel and the guiding structure can be a guiding groove, or a guiding wheel or a guiding column.

[0089] 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 rotates toward the side away from the box body 9. The second end of the linkage member pulls the first end of the towing rope 7. Since the second end of the towing rope 7 is connected to the end of the sliding member 4 away from the hinge position, the towing rope 7 pulls the sliding member 4 to move along the width direction toward the side away from the hinge position, thereby driving the cabinet door 2 to move toward the side away from the hinge position. At the same time, the elastic member 5 is compressed along the direction away from the hinge position to generate elastic potential energy.

[0090] 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 rotates toward the side close to the box body 9. The pulling force of the second end of the linkage member on the towing rope 7 gradually becomes smaller, and the towing rope 7 becomes slack. At this time, the elastic member 5 moves toward the direction close to the hinge position under the drive of the elastic potential energy, thereby driving the sliding member 4 to move along the width direction toward the side close to the hinge position, and then driving the cabinet door 2 to move toward the side close to the hinge position.

[0091] In this embodiment, the first end of the connecting member is arranged to deviate from the hinge position between the door 1 and the box body 9, so that the second end of the connecting member can pull the traction rope 7 to drive the sliding member 4 to move along the width direction of the door 1, and the elastic member 5 can accumulate 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. The use of the traction rope 7 and the elastic member 5 can realize the movement of the cabinet door 2 in the width direction relative to the cabinet door 1. The structure is simple and easy to implement.

[0092] In some embodiments, Figure 2 As shown, the guide member 3 is provided with a first limiting portion 31 and a second limiting portion 32 .

[0093] The first limiting portion 31 is disposed close to the hinge position, the second limiting portion 32 is away from the hinge position and is located on the side of the sliding member 4 away from the hinge position, and the traction rope 7 is sequentially wound around the first limiting portion 31 and the second limiting portion 32 .

[0094] It can be understood that the first limiting portion 31 and the second limiting portion 32 are used to guide and limit the winding path of the traction rope 7, so that the first end of the traction rope 7 can be connected to the second end of the connecting member, and the second end of the traction rope 7 can be connected to the end of the sliding member 4 away from the hinge position, so that when the traction rope 7 is pulled along with the connecting member, the sliding member 4 can move toward the side away from the hinge 10, thereby ensuring the stability and reliability of the traction rope 7 in the process of pulling the sliding member 4.

[0095] In some embodiments, Figure 2 As shown, at least one of the first limiting portion 31 and the second limiting portion 32 includes a roller or a protrusion.

[0096] It is understandable that the traction rope 7 can be passed through the roller and, under the guidance of the roller, pull the sliding member 4 along a set path, or the traction rope 7 can be wrapped around the outer wall of the protrusion, and both the roller and the protrusion can guide the traction rope 7 to change direction or move in a specific direction, so as to guide the traction rope 7 to stably pull the sliding member 4 along the set path.

[0097] Specifically, the first limiting portion 31 of the present embodiment is configured as a protrusion, and the second limiting portion 32 is also configured as a protrusion.

[0098] In some embodiments, Figure 2 As shown, the guide member 3 includes a fixing plate 33 and a sliding groove 34 .

[0099] The fixing plate 33 is configured to be provided on the door 1 .

[0100] The slide groove 34 is disposed on the fixed plate 33 and extends along the width direction. At least a portion of the sliding member 4 is movably disposed in the slide groove 34 along the width direction.

[0101] It is understandable that the fixing plate 33 of this embodiment is used for fixedly connecting with the cabinet door 1, and the sliding groove 34 is used to guide 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 34, it is ensured that the sliding member 4 can move stably and reliably along the width direction of the cabinet door 1.

[0102] In some embodiments, such as Figure 1 and Figure 2 shown, the guiding member 3 further includes a sliding sleeve 35, and the sliding sleeve 35 is arranged at one end of the sliding groove 34 away from the hinge position.

[0103] The sliding member 4 includes a guiding rod 41 and a slider 42. The guiding rod 41 is inserted through the sliding sleeve 35, and a sliding contact 45 is arranged on the guiding rod 41. The sliding contact 45 is movably arranged in the sliding groove 34 along the width direction; the slider 42 is connected to the guiding rod 41 and is configured to be connected to the cabinet door 2.

[0104] Wherein, the elastic member 5 is arranged between the sliding sleeve 35 and the sliding contact 45.

[0105] It is understandable that the sliding groove 34 of this embodiment is arc-shaped to be adapted to the outer wall of the guiding rod 41. The sliding sleeve 35 is used to guide the movement of the guiding rod 41 relative to the sliding groove 34. And as the sliding member 4 moves on the sliding groove 34, the sliding contact 45 also moves accordingly. The sliding sleeve 35 is fixedly arranged relative to the fixing plate 33, and the elastic member 5 is limited between the sliding sleeve 35 and the sliding contact 45. When the guiding rod 41 moves towards the side away from the hinge 10, the sliding contact 45 moves towards the sliding sleeve 35, causing the elastic member 5 between the sliding sleeve 35 and the sliding contact 45 to be compressed. When the guiding rod 41 moves towards the side close to the hinge 10, the elastic member 5 releases elastic potential energy and elongates, and the sliding contact 45 moves towards the direction away from the sliding sleeve 35. The sliding sleeve 35 and the sliding contact 45 constrain the elastic member 5 from both sides of the elastic member 5 to ensure the reliability of the compression and elongation of the elastic member 5.

[0106] Moreover, one end of the slider 42 is connected to the guiding rod 41, and the other end is connected to the cabinet door 2, so that when the guiding 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.

[0107] In some embodiments, such as Figure 1 and Figure 2 shown, the elastic member 5 includes a spring. The spring is sleeved on the outside of the guiding rod 41 and is limited between the sliding sleeve 35 and the sliding contact 45.

[0108] It is understandable that when the elastic member 5 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. 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 35 and the sliding contact 45 can limit both sides of the spring from both ends of the guide rod 41, facilitating the stopping at both ends when the spring is compressed and elongated. The spring in this embodiment makes the structure for resetting the cabinet door 2 relative to the box door 1 simple and compact, with a small volume, saving the installation space of the cabinet door 2.

[0109] In some embodiments, as Figure 3 shown, the sliding member 4 further includes: a first connecting arm 43 and a second connecting arm 44.

[0110] 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.

[0111] The sliding sleeve 35 and the sliding contact 45 are located between the first connecting arm 43 and the second connecting arm 44.

[0112] It is understandable 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 box door 1, it is easier to fit the width direction.

[0113] 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 33 is installed at the top of the box door 1, and the cabinet door 2 and the box door 1 can be parallel and fit, ensuring the flatness when the cabinet door 2 is installed on the box door 1. Moreover, it is beneficial for the cabinet door 2 to move along the box door 1.

[0114] In some embodiments, as Figures 5 to 10 shown, the sliding door mechanism further includes: a sliding module 8.

[0115] The sliding module 8 is configured to be arranged between the box 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 box door 1 along the width direction.

[0116] It is understandable that due to the self - weight of the cabinet door 2, during the process of the cabinet door 2 moving relative to the box door 1, the cabinet door 2 may vibrate or tilt. The sliding module 8 can provide stable support and guiding functions, guiding the reliable and stable movement of the cabinet door 2 relative to the box door 1.

[0117] 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 installed on the cabinet door 1, and the second sliding member 82 can be installed on the door 2. Alternatively, the first sliding member 82 can be installed on the door 2, and the second sliding member 82 can be installed 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.

[0118] In some embodiments, as Figure 6 and Figure 7 shown, the sliding module 8 includes: a slide rail 81 and a moving member.

[0119] The slide rail 81 is configured to be provided on the cabinet door 1 and extend in the width direction.

[0120] The moving member is movably provided on the slide rail 81 in the width direction, and the moving member is configured to be detachably connected to the door 2.

[0121] It can be understood that the slide rail 81 can be in the form of a chute, 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; the moving member is correspondingly in the form of a structure that wraps the slide rail and moves.

[0122] The moving member can move along the extending 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.

[0123] 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.

[0124] 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.

[0125] In some embodiments, as Figure 5 shown, there are at least two sets of sliding modules 8. The first end of the traction rope 7 is connected to the driving member 6, the second end of the traction rope 7 is connected to the sliding member 4, the elastic member 5 is provided between the guiding member 3 and the sliding member 4, and the sliding member 4 is connected to the moving member of one of the at least two sets of sliding modules 8.

[0126] Among them, the traction rope 7 and the elastic member 5 are used to drive the sliding member 4 to drive the moving member to move along the slide rail 81.

[0127] 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 traction rope 7 to drive the moving member to move along the slide rail 81. Further, the driving assembly can control the traction rope 7 to drive the cabinet door 2 to move relative to the box door 1 along the extending 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 guiding, 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 smooth and stable movement of the cabinet door 2 relative to the box door 1 can be realized, improving the convenience and reliability of use, and facilitating the precise control and smooth movement of the cabinet door 2.

[0128] 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. 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.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] Further, the sliding member 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 along the width direction on the slide rail 81. 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 in this embodiment is rolling friction, which reduces the frictional force and improves 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.

[0133] Optionally, as Figure 6 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 traction rope 7, and the driving member 6 is connected to the traction rope 7 so that the driving member 6 can control the traction rope 7 to drive the movement of the sliding body 821.

[0134] 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 or horizontal direction, and the hanging part 832 is hung on the sliding member 82.

[0135] It can be understood that a slight adjustment in the vertical or horizontal direction can be achieved 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 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.

[0136] 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.

[0137] 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.

[0138] like Figure 9 and Figure 10 As shown, the process of installing the hanging member 83 and the cabinet door 2 is as follows:

[0139] 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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 door body assembly as above. 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.

[0148] 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.

[0149] 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.

[0150] 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 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.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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 use convenience but also can avoid the possible damage of 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.

[0155] 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 between a first position and a second position relative to the box door 1 along the width direction.

[0156] In the case where 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.

[0157] 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.

[0158] 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.

[0159] 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 wall of the cabinet door 2 and the side wall of the box door 1 are misaligned and form a gap 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.

[0160] 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.
