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.

[0054] The following is combined with Figures 1 to 11, the sliding door mechanism, door body assembly, and refrigeration device provided by the embodiments of the present utility model are described in detail through specific embodiments and their application scenarios.

[0055] In the first aspect, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, an embodiment of the present utility model provides a sliding door mechanism applied to a refrigeration device, including: a trigger member 3 and a linear drive member 4.

[0056] The trigger member 3 is used to obtain the opening and closing signal of the cabinet door 1 of the refrigeration device.

[0057] The linear drive member 4 is configured to be disposed between the cabinet door 1 and the door 2 and connected to the trigger member 3.

[0058] Wherein, the linear drive member 4 is used to drive the door 2 to move along the width direction of the cabinet door 1 according to the opening and closing signal fed back by the trigger member 3.

[0059] It can be understood that, as Figure 5 shown, the box body 6 is provided with a hinge 7, and a hinge shaft is provided on the hinge 7. The cabinet door 1 is rotatably provided on the hinge shaft to realize the opening or closing of the cabinet door 1 relative to the box body 6.

[0060] The linear drive member 4 can be installed on the cabinet door 1, and the output end of the linear drive member 4 is connected to the door 2. Or, the linear drive member 4 can also be installed on the door 2, and the output end of the linear drive member 4 is connected to the cabinet door 1. The trigger member 3 is electrically connected to the linear drive member 4, or the trigger member 3 is wirelessly communicatively connected to the linear drive member 4.

[0061] This embodiment further includes a controller. The trigger member 3 is electrically connected to the controller, and the controller is electrically connected to the linear drive member 4. The controller is used to receive the opening and closing signal of the cabinet door 1 fed back by the trigger member 3 and control the movement of the linear drive member 4 to drive the door 2.

[0062] Specifically, the trigger member 3 can be a photoelectric switch, and the photoelectric switch judges the opening and closing state of the cabinet door 1 by detecting the relative distance between the cabinet door 1 and the box body 6. The trigger member 3 can also be an angle sensor, and judges the opening and closing state of the cabinet door 1 by detecting the relative angle between the cabinet door 1 and the box body 6. The linear drive member 4 can be a cylinder, a hydraulic cylinder, or an electric push rod.

[0063] In practical applications, during the opening process of the cabinet door 1, the linear drive member 4 drives the cabinet door 2 to move away from the hinge 7 in the width direction of the cabinet door 1, that is, move to the left relative to the cabinet door 1, so as to avoid interference between the cabinet door 2 and the cabinet body around the refrigeration equipment; during the closing process of the cabinet door 1, the linear drive member 4 drives the cabinet door 2 to move towards the hinge 7 in the width direction of the cabinet door 1, that is, move to the right relative to the cabinet door 1, so as to ensure that the cabinet door 2 can avoid the cabinet body around the refrigeration equipment when the cabinet door 1 is closed and reset the cabinet door 2.

[0064] For the sliding door mechanism shown in this embodiment, by using the trigger member 3 to obtain the opening and closing signal of the cabinet door 1, and arranging the linear drive member 4 between the cabinet door 1 and the cabinet door 2. When the cabinet door 1 is opened, the linear drive member 4 drives the cabinet door 2 to move away from the hinge 7 in the width direction of the cabinet door 1, so that the cabinet door 2 and the cabinet body on the side are prevented from interfering with the cabinet body. When the cabinet door 1 is closed, the linear drive member 4 drives the cabinet door 2 to move towards the hinge 7 in the width direction of the cabinet door 1, so that the cabinet door 2 returns to its original position, ensuring that the cabinet door 2 does not interfere with the cabinet body around the refrigeration equipment.

[0065] In some embodiments, such as Figure 3 and Figure 4 shown, the trigger member 3 includes a displacement sensor, and the displacement sensor is used to detect the rotation direction of the cabinet door 1 to obtain the opening and closing signal.

[0066] It can be understood that the displacement sensor can be an angular displacement sensor. The angular displacement sensor of this embodiment is installed on the hinge axis of the hinge 7, and the angular displacement sensor can detect the rotation direction and rotation angle of the cabinet door 1 around the hinge axis.

[0067] The displacement sensor can detect the rotation direction of the cabinet door 1 relative to the cabinet body 6 when the cabinet door 1 rotates. According to the opening and closing state of the cabinet door 1, the opening and closing signal is divided into an opening signal and a closing signal; when the cabinet door 1 is opened, the displacement sensor feeds back the opening signal to the linear drive member 4, and the linear drive member 4 drives the cabinet door 2 to move away from the hinge 7 in the width direction of the cabinet door 1; correspondingly, when the cabinet door 1 is closed, the displacement sensor feeds back the closing signal to the linear drive member 4, and the linear drive member 4 drives the cabinet door 2 to move towards the hinge 7 in the width direction of the cabinet door 1.

[0068] Further, as the opening or closing amplitude of the cabinet door 1 varies, the displacement sensor can also obtain the rotation angle of the cabinet door 1. The linear drive member 4 can determine the preset value of the movement according to the rotation angle. When the cabinet door 1 is in the open state, according to the rotation angle when the cabinet door 1 is opened, the stroke of the telescopic end of the linear drive member 4 is determined, and then the linear drive member 4 drives the cabinet door 2 to move a preset distance away from the hinge 7 to avoid interference with the external cabinet body; correspondingly, when the cabinet door 1 is in the closed state, according to the rotation angle when the cabinet door 1 is closed, the stroke of the telescopic end of the linear drive member 4 is determined, and then the linear drive member 4 drives the cabinet door 2 to move a preset distance towards the hinge 7 to avoid interference between the cabinet door 2 and the external cabinet body, and finally, the cabinet door 2 is reset.

[0069] In this embodiment, by setting the trigger member 3 as a displacement sensor, the opening and closing signal and the rotation angle of the cabinet door 1 are synchronously obtained, and then the preset value of the movement of the cabinet door 2 along the width direction of the cabinet door 1 is accurately determined, so that the movement of the cabinet door 2 relative to the cabinet door 1 can be consistent with the rotation amplitude of the cabinet door 1, avoiding interference and ensuring the beauty and reliability of the movement process of the cabinet door 2 relative to the cabinet door 1.

[0070] In some embodiments, as Figure 1 shown, the trigger member 3 includes a push-button switch for receiving the pressing input of the corresponding opening and closing signal; the push-button switch is configured to be connected to the opening mechanism that drives the cabinet door 1 to open and close.

[0071] It can be understood that the opening mechanism in this embodiment is used to open or close the cabinet door 1. The push-button switch is connected to the opening mechanism, and when the push-button switch is triggered, it controls the opening mechanism to open or close the cabinet door 1.

[0072] Generally, built-in refrigerators are designed in a handleless style, using a pressure opening system or a hidden notch instead of a traditional handle, or a push-button switch can also be used to control the opening and closing of the cabinet door 1 of the built-in refrigerator. The push-button switch in this embodiment is arranged on the cabinet door of the refrigerator and is used to control the opening and closing of the cabinet door 1 by pressing the button of the push-button switch. At the same time, the push-button switch feeds back the opening and closing signal of the cabinet door 1 to the linear drive member 4, and the linear drive member 4 drives the cabinet door 2 to move along the width direction of the cabinet door 1.

[0073] Specifically, after the push-button switch receives the input instruction for the cabinet door 1 to open, the push-button switch feeds back the opening signal to the opening mechanism and the linear drive member 4. The opening mechanism drives the cabinet door 1 to open. At the same time, the linear drive member 4 drives the cabinet door 2 to move away from the hinge 7 along the width direction of the cabinet door 1 to ensure that the cabinet door 2 does not interfere with the surrounding parts while the cabinet door 1 is opening.

[0074] After the push-button switch receives the input instruction that the cabinet door 1 is closed, the push-button switch feeds back the closing signal to the door-opening mechanism and the linear drive member 4. The door-opening mechanism drives the cabinet door 1 to close. At the same time, the linear drive member 4 drives the cabinet door 2 to move in the width direction of the cabinet door 1 towards the hinge 7, so as to ensure that when the cabinet door 1 is closed, the cabinet door 2 does not interfere with the surrounding parts, and the cabinet door 2 can be reset with the complete closing of the cabinet door 1 to ensure the aesthetics of the cabinet door 2.

[0075] In this embodiment, the trigger member 3 is set as a push-button switch. The push-button switch can not only control the opening and closing of the cabinet door 1 by the door-opening mechanism, but also feed back the opening and closing signal of the cabinet door 1 to the linear drive member 4, so that the linear drive member 4 drives the cabinet door 2 to move in the width direction of the cabinet door 1, enabling the cabinet door 2 to open and close synchronously with the cabinet door 1 while avoiding interference with the surrounding cabinet body, ensuring the synchronism and aesthetics of the opening and closing of the cabinet door 1 and the cabinet door 2.

[0076] In some embodiments, the linear drive member 4 includes a linear motor or a telescopic rod.

[0077] It can be understood that as Figure 3 and Figure 4 shown, the linear motor is installed on the cabinet door 1, and the output end of the linear motor is connected to the cabinet door 2. The linear motor drives the cabinet door 2 to move in the width direction of the cabinet door 1 through linear driving of the cabinet door 2. The reaction speed of the linear motor is fast and the sensitivity is high. For the small-distance movement adjustment of the cabinet door 2 along the cabinet door 1, it can quickly respond and accurately adjust the movement distance, realizing the reliability and stability of the movement of the cabinet door 2 relative to the cabinet door 1.

[0078] The fixed end of the telescopic rod is connected to the cabinet door 1, and the telescopic end of the telescopic rod is connected to the cabinet door 2. The distance between the rotation center of the cabinet door 2 and the cabinet door 1 is adjusted by the telescopic movement of the telescopic rod, so as to realize the movement of the cabinet door 2 in the width direction of the cabinet door 1. The telescopic rod is flexible to adjust and saves space, and can flexibly adjust the relative movement between the cabinet door 1 and the cabinet door 2 in the limited space between the cabinet door 1 and the cabinet door 2. Moreover, the design of the telescopic rod is simple and can be coordinated with the overall home environment, improving the consistency of the home environment.

[0079] Specifically, the telescopic rod can be an electric push rod or a cylinder.

[0080] In some embodiments, as Figure 5 、 Figure 6 、 Figure 7 and Figure 8 shown, the sliding door mechanism further includes: a sliding module 5.

[0081] The sliding module 5 is configured to be arranged between the cabinet door 1 and the cabinet door 2, and the sliding module 5 is used to guide the cabinet door 2 to move relative to the cabinet door 1 in the width direction.

[0082] It is understandable that due to the gravity of the cabinet door 2 itself, 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 5 can provide stable support and guiding functions, guiding the cabinet door 2 to move reliably and stably relative to the box door 1.

[0083] The sliding module 5 includes a first sliding member and a second sliding member. The first sliding member and the second sliding member are slidably engaged in the width direction. The first sliding member can be installed on the box door 1 and the second sliding member can be installed on the cabinet door 2, or the first sliding member can be installed on the cabinet door 2 and the second sliding member can be installed on the box door 1. The sliding module 5 realizes the relative movement of the box door 1 and the cabinet door 2 through the relative sliding of the first sliding member and the second sliding member.

[0084] In some embodiments, as Figure 7 and Figure 8 shown, the sliding module 5 includes a slide rail 51 and a moving member. The slide rail 51 is configured to be provided on the box door 1 and extend in the width direction; the moving member is movably provided on the slide rail 51 in the width direction, and the moving member is configured to be detachably connected to the cabinet door 2.

[0085] It is understandable that the slide rail 51 can be in the structural form of a chute, and the moving member is correspondingly in the structural form of a structure that slides along the chute; the slide rail 51 can also be in the structural form of a slide bar; the moving member is correspondingly in the structural form of a structure that wraps the slide rail and moves.

[0086] The moving member can move along the extending direction of the slide rail 51. Based on the guiding and supporting functions of the slide rail 51, the moving member can move stably and reliably along the slide rail 51. And, based on the high rigidity of the slide rail 51, a high straightness can be provided for the moving member, so that the cabinet door 2 can move stably and reliably along the width direction of the box door 1.

[0087] 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.

[0088] 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.

[0089] In some embodiments, as Figure 5 and Figure 6 shown, at least two sets of sliding modules 5 are provided; the linear drive member 4 is configured to be provided on the box door 1 and connected to the moving member of one of the at least two sets of sliding modules 5 to drive the moving member to move along the slide rail 51.

[0090] It is understandable that multiple sets of sliding modules 5 can be provided. One set of the sliding modules 5 is used to connect with the linear drive 4 so that the linear drive 4 can drive the moving member to move along the slide rail 51, and further enable the linear drive 4 to drive the cabinet door 2 to move relative to the box door 1 along the extension direction of the slide rail 51. The sliding module 5 connected to the linear drive 4 serves as an active driving mechanism, realizing the integrated design of the linear drive 4 and the sliding module 5. For cooperation and guidance, the slide rails 51 in each sliding module 5 are arranged in parallel, ensuring that the cabinet door 2 can be accurately guided during movement, avoiding interference with the side wall of the cabinet body. Moreover, the remaining multiple sets of sliding modules 5 serve as passive guiding mechanisms. Through the cooperation of the multiple sets of sliding modules 5, the smooth and stable movement of the cabinet door 2 relative to the box door 1 can be achieved, improving the convenience and reliability of use, and facilitating the precise control and smooth movement of the cabinet door 2.

[0091] Specifically, four sets of sliding modules 5 are provided in this embodiment. Two sets of the sliding modules 5 are arranged along the width direction and are located between the upper end of the box door 1 and the upper end of the cabinet door 2. The other two sets of sliding modules 5 are arranged along the width direction and are located between the lower end of the box door 1 and the lower end of the cabinet door 2. And, one set of the two sets of sliding modules 5 located at the upper end and close to the hinge 7 is connected to the linear drive 4. The remaining three sets of sliding modules 5 are respectively arranged at the remaining triangles of the box door 1. The slide rails 51 among the four sets of sliding modules 5 are arranged in parallel.

[0092] Correspondingly, among the three sets of passive sliding modules 5, the sliding module 5 located at the upper end of the box door 1 has the same structure as the sliding module 5 located at the lower end of the box door 1 and is symmetrically arranged on the box door 1.

[0093] In some embodiments, as Figure 7 and Figure 8 shown, the moving member includes a sliding member 52 and a hanging member 53. The sliding member 52 is movably arranged along the width direction on the slide rail 51. The hanging member 53 is configured to be connected to the cabinet door 2 and is hung on the sliding member 52.

[0094] It is understandable that the hanging member 53 is used to connect the sliding member 52 and the cabinet door 2 to realize the movement of the cabinet door 2 relative to the box door 1 driven by the sliding member 52. Moreover, the hanging member 53 is configured to be detachably connected to the cabinet door 2.

[0095] Further, the sliding member 52 of this embodiment includes a sliding body 521 and an adapter base 522. The sliding body 521 and the adapter base 522 are fixedly connected. A support frame 511 is provided on the slide rail 51. A round hole is provided on the support frame 511, and a ball is installed in the round hole. The sliding body 521 is in rolling contact with the slide rail 51 to move on the slide rail 51 in the width direction. A first card slot 5221 is provided on the adapter base 522 for hanging the hanging member 53 on the sliding body 521. The relative movement between the sliding body 521 and the slide rail 51 in this embodiment is rolling friction, so as to reduce the frictional force and improve the moving efficiency of the moving member. This design can accurately control the movement track and distance of the cabinet door 2, avoid interference with the side wall of the cabinet body, and realize the smooth opening and closing of the box door 1.

[0096] Optionally, as Figure 7 shown, the sliding module 5 is an active driving mechanism. The sliding module 5 is connected to the linear driving member 4. In this embodiment, a fixing hole 5211 is provided on the sliding body 521 for fixedly connecting the output end of the linear driving member 4 to the sliding body 521, so that the sliding module 5 and the linear driving member 4 are integrally arranged.

[0097] In some embodiments, as Figures 7 to 11 shown, the hanging member 53 includes a fixing base 531 and a hanging part 532; the fixing base 531 is configured to be connected to the cabinet door 2, and the hanging part 532 is adjustably arranged on the fixing base 531 in the vertical direction or the horizontal direction, and the hanging part 532 is hung on the sliding member 52.

[0098] It can be understood that a small amount of adjustment in the vertical direction or the horizontal direction can be realized between the hanging part 532 and the fixing base 531. Thus, by adjusting the relative position between the hanging part 532 and the fixing base 531, 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.

[0099] Specifically, the fixing base 531 is connected to the cabinet door 2 to provide additional structural support for the cabinet door 2. An installation groove is formed on the fixing base 531 for accommodating the hanging part 532; the hanging part 532 is slidably arranged in the installation groove, and a first card joint 5321 is formed on the hanging part 532 to adjust the relative position between the cabinet door 2 and the box door 1 by adjusting the position of the hanging part 532 in the installation groove. Through the adjustable design, the user can adjust the position of the cabinet door 2 according to actual needs to meet the requirements of different usage scenarios.

[0100] Specifically, the first card connector 5321 is a U-shaped hook facing downward, which can pass through the notch and slide into the first card slot 5221. The hanging member 532 is provided with a first rectangular hole extending in the up and down direction. The fixed seat 531 is provided with two mounting holes and a mounting groove extending left and right between the two mounting holes. The side wall of the mounting groove is provided with a second rectangular hole extending in the left and right direction. The hanging member 532 can slide in the mounting groove. By controlling the position of the hanging member 532 in the mounting groove, the hanging member 532 can move up and down relative to the fixed seat 531. A screw can be set to pass through the first rectangular hole on the mounting groove and the second rectangular hole on the hanging member 532, and a hanging member 532 that can be adjusted in both the up and down and left and right directions can be formed. Through the relative position of the mounting holes of the fixed seat 531 and the cabinet door 2, the position of the fixed seat 531 and the cabinet door 2 can be adjusted in the up and down, left and right directions.

[0101] As Figure 10 and Figure 11 shown, the process of installing the hanging member 53 on the cabinet door 2 is as follows:

[0102] Insert the hanging member 532 into the mounting groove of the fixed seat 531. Use screws to pass through the second rectangular hole, the first rectangular hole and the cabinet door 2 to integrally connect the fixed seat 531 to the cabinet door 2. Hang the first card connector 5321 on the hanging member 532 connected in the first card slot 5221 to complete the connection between the hanging member 532 and the adapter 522. Then, by observing the positional relationship between the cabinet door 2 and the box door 1, check whether there is a deviation. If there is a deviation, the position can be adjusted through the first rectangular hole and the second rectangular hole. When the deviation is large, the screw can be removed, the hanging member 53 is separated from the cabinet door 2, and the position of the hanging member 53 is adjusted. For the cabinet door 2 and the fixed seat 531 and the hanging member 532 assembly, the position of the hanging member 532 is adjusted. If the positional relationship meets the requirements and no adjustment is required, then use screws to pass through the mounting holes on both sides of the fixed seat 531 and the cabinet door 2 to further fix the cabinet door 2 and the fixed seat 531 to keep its position stable. Through the above method, not only can the position of the fixed seat 531 be finely adjusted, but also it can be ensured that all fixings are firm, and the positional relationship between the cabinet door 2 and the box door 1 is accurate and error-free.

[0103] In the second aspect, as Figure 1 shown, the embodiment of the present invention further provides a door assembly, including: a box door 1, a cabinet door 2 and a sliding door mechanism. The box door 1 is configured to be rotatably arranged on the cabinet of the refrigeration device 6 to open or close the storage compartment in the cabinet 6. The cabinet door 2 is movably arranged on the box door 1 along the width direction of the box door 1. The sliding door mechanism is the sliding door mechanism as described in any one of the above.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] For the door body assembly shown in this embodiment, by rotatably connecting the cabinet door 1 to the cabinet body 6, movably arranging the cabinet door 2 on the outside of the cabinet door 1 along the width direction of the cabinet door 1, and connecting the cabinet door 1 and the cabinet door 2 by using a sliding door mechanism, during the opening or closing process of the sliding door mechanism, the cabinet door 2 is controlled to move relative to the cabinet door 1, so that the cabinet door 1 can avoid the side cabinet body during the opening and closing processes, thereby avoiding the interference between the cabinet door 2 and the outside when the cabinet door 1 rotates, and meeting the use requirements of users in different scenarios.

[0108] 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.

[0109] 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.

[0110] In some embodiments, as Figure 1 shown, the door body assembly and the cabinet body 6 are configured to be arranged in the accommodation space between the first cabinet body 8 and the second cabinet body 9.

[0111] During the opening or closing process of the cabinet door 1, the linear driving member 4 is used to change the position of the cabinet door 2 on the cabinet door 1, so that the cabinet door 2 can avoid the side wall of the first cabinet body 8 or the second cabinet body 9.

[0112] It is understandable that an opening is provided on the outer side of the accommodation space between the first cabinet body 8 and the second cabinet body 9. This design enables the door assembly and the box body 6 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 sliding door mechanism is configured to drive the cabinet door 2 to move a preset distance on the box door 1 in a direction away from or close to the box body 6, so that the cabinet door 2 avoids the side walls of the first cabinet body 8 and the second cabinet body 9.

[0113] During the process of the box door 1 passing through the opening to control the opening or closing of the accommodation space, the sliding door mechanism is configured to drive the cabinet door 2 to move on the box door 1 in a direction away from or close to the box body 6, and is also capable of controlling the cabinet door 2 to move a preset distance. This design is mainly to avoid interference between the cabinet door 2 and the side walls of the first cabinet body 8 and the second cabinet body 9. Through the movement of the preset distance, the box door 1 can be smoothly opened or closed without colliding or jamming with the side walls of the cabinet body.

[0114] For example, during the opening process of the box door 1, the sliding door mechanism drives the cabinet door 2 to move a preset distance along the box door 1 in a direction away from the hinge 7. In this way, the cabinet door 2 can smoothly avoid the side wall of the second cabinet body 9, enabling the box door 1 to be fully opened, facilitating users to access items.

[0115] Similarly, during the closing process of the box door 1, the sliding door mechanism drives the cabinet door 2 to move a preset distance along the box door 1 in a direction close to the hinge 7. In this way, the cabinet door 2 can smoothly avoid the side wall of the first cabinet body 8, enabling the box door 1 to be fully closed, maintaining the overall aesthetics and sealing performance.

[0116] In some embodiments, as Figure 3 and Figure 4 shown, the box door 1 is rotatably connected to the box body 6 through the hinge 7; the cabinet door 2 can move between a first position and a second position relative to the box door 1 in the width direction.

[0117] 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 7 is arranged close to the hinge 7.

[0118] 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 7 is arranged away from the hinge 7 to avoid the side wall of the first cabinet body 8 or the second cabinet body 9.

[0119] It is understandable 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 the closed state, and the side of the cabinet door 2 is at a first distance (close to zero) relative to the hinge 7 of the refrigeration device. For example, the side of the cabinet door 2 and the side of the box door 1 are flush. At this time, the cabinet door 2 can completely cover the box door 1, ensuring that the door body of the refrigeration device exposed in the accommodation space is consistent with the surrounding first cabinet body 8 and second cabinet body 9 in appearance.

[0120] When the cabinet door 1 opens the storage compartment, 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 7 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 8 or the second cabinet body 9, so as to prevent the cabinet door 2 from colliding with or interfering with the first cabinet body 8 or the second cabinet body 9 due to the opening of the cabinet door 1.

[0121] In some embodiments, as Figure 5 shown, the door body assembly is provided with a sliding door mechanism; the cabinet door 1 is provided with a groove 11, and the sliding module 5 is arranged in the groove 11.

[0122] The door body assembly further includes a decorative member; the decorative member is used to cover the notch end of the groove 11.

[0123] It can be understood that the sliding module 5 is arranged in the groove 11, which can enable the cabinet door 1 to form a stable cooperation with the sliding module 5 during the opening and closing processes of the cabinet door 1, reduce the overall thickness of the cabinet door 1 and the cabinet door 2, and moreover, the sliding module 5 is hidden in the groove 11. When the cabinet door 2 moves relative to the cabinet door 1, the user can only observe the movement of the cabinet door 2 relative to the cabinet door 1 and cannot see the sliding of the sliding module 5, enhancing the aesthetics and consistency of the movement process of the cabinet door 2.

[0124] In this embodiment, four grooves 11 are provided, and the four grooves 11 are respectively arranged at the four corners of the cabinet door 1. A plurality of threaded holes are provided in the grooves 11, and through holes corresponding to the threaded holes in the grooves 11 are provided on the slide rail 51. In this way, the slide rail 51 can be fixed in the groove 11 by setting bolts on the slide rail 51.

[0125] When the refrigeration device is installed in a fully embedded manner, it is necessary to provide a cabinet door 2 on the outer side of the cabinet door 1. The sliding module 5 is arranged in the groove 11 on the cabinet door 1, which can ensure the aesthetics of the cabinet door 2 when the cabinet door 1 and the cabinet door 2 move relative to each other.

[0126] When the refrigeration device is installed in a flat embedded manner, the cabinet door 2 does not need to be installed on the outer side of the cabinet door 1. In order to ensure the aesthetics of the outer side of the cabinet door 1, the decorative member is covered on the groove 11 to ensure the aesthetics of the appearance of the refrigeration device.

[0127] Specifically, the decorative member can be a decorative cover having the same material and color as the cabinet door 1.

[0128] The user can select whether to install the cabinet door 2 according to actual needs and select a suitable connection method according to different application scenarios.

[0129] In a third aspect, as Figure 1 、 Figure 3 and Figure 4As shown in the figure, an embodiment of the present utility model further provides a refrigeration device, including: a box body 6 and the door body assembly as above. The box body 6 has a storage compartment, and the box door 1 is rotatably arranged on the box body 6 to open or close the storage compartment.

[0130] Specifically, since the refrigeration device includes a door body assembly, and the specific structure of the door body assembly refers to the above embodiment, the refrigeration device shown in this embodiment includes all the technical solutions of the above embodiment. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above embodiment, which will not be elaborated here one by one.

[0131] It can be understood that during the opening process of the box door 1, the sliding door mechanism drives the cabinet door 2 to move away from the hinge 7, which can avoid interference between the cabinet door 2 and the cabinet around the refrigeration device. During the closing process of the box door 1, the sliding door mechanism drives the cabinet door 2 to move towards the hinge 7 to ensure that the cabinet door 2 can avoid the cabinet around the refrigeration device when closed.

[0132] The combination of the box door 1 and the cabinet door 2 enables the refrigeration device to avoid interference between the cabinet door 2 and the cabinet around the refrigeration device during both opening and closing, 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.

[0133] The refrigeration device in this application is, for example, applied as a refrigerator. However, it should be understood that the refrigeration device of this application can also be applied as a freezer or any other suitable device, which is not limited here.

[0134] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model, rather than to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present utility model do not depart from the spirit and scope of the technical solutions of the present utility model, and should all be covered within the scope of the claims of the present utility model.
