[0056] Next, in conjunction with Figures 1 to 11 , the sliding door mechanism, door body assembly, and refrigeration device provided by the embodiments of the present utility model will be described in detail through specific embodiments and their application scenarios.

[0057] In the first aspect, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the embodiments of the present utility model provide a sliding door mechanism applied to a refrigeration device, including: a trigger member 3, a rotary drive member 4, and a transmission assembly 10.

[0058] The trigger member 3 is used to obtain the opening and closing signal of the cabinet door 1 of the refrigeration device; the rotary drive member 4 is arranged on the cabinet door 1 and is connected to the trigger member 3; the transmission assembly 10 is arranged between the rotary drive member 4 and the cabinet door 2.

[0059] Wherein, the rotary drive member 4 is used to control the transmission assembly 10 to drive the cabinet 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.

[0060] It can be understood that, as Figure 8 shown, the box body 6 is installed with a hinge 7, and a hinge shaft is arranged on the hinge 7. The cabinet door 1 is rotatably arranged on the hinge shaft to realize the opening or closing of the cabinet door 1 relative to the box body 6.

[0061] The rotary drive member 4 is installed on the cabinet door 1, and the output end of the rotary drive member 4 is connected to the transmission assembly 10. The trigger member 3 is electrically connected to the rotary drive member 4, or the trigger member 3 is wirelessly communicatively connected to the rotary drive member 4.

[0062] This embodiment further includes a controller. The trigger member 3 is electrically connected to the controller, and the controller is electrically connected to the rotary 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 rotary drive member 4 to rotate and drive the transmission assembly 10, and the transmission assembly 10 drives the movement of the cabinet door 2.

[0063] Specifically, the trigger 3 can be a photoelectric switch, which determines the opening and closing state of the door 1 by detecting the relative distance between the door 1 and the cabinet body 6. The trigger 3 can also be an angle sensor, which determines the opening and closing state of the door 1 by detecting the relative angle between the door 1 and the cabinet body 6. The rotary driving member 4 can be a motor or a motor.

[0064] The transmission assembly 10 is used to convert the rotary motion of the rotary driving member 4 into a linear motion and drive the door 2 to move linearly relative to the door 1.

[0065] Optionally, the transmission assembly 10 can be a crank-slider mechanism or a lead screw mechanism.

[0066] In practical applications, during the opening process of the door 1, the rotary driving member 4 drives the transmission assembly 10. The transmission assembly 10 converts the rotary motion into a linear motion and drives the door 2 to move away from the hinge 7 along the width direction of the door 1, that is, move to the left relative to the door 1, so as to avoid interference between the door 2 and the cabinet body around the refrigeration equipment. During the closing process of the door 1, the rotary driving member 4 drives the transmission assembly 10. The transmission assembly 10 converts the rotary motion into a linear motion and drives the door 2 to move towards the hinge 7 along the width direction of the door 1, that is, move to the right relative to the door 1, so as to ensure that the door 2 can avoid the cabinet body around the refrigeration equipment when the door 1 is closed and reset the door 2.

[0067] For the sliding door mechanism shown in this embodiment, by using the trigger 3 to obtain the opening and closing signal of the door 1, arranging the rotary driving member 4 on the door 1, arranging the transmission assembly 10 between the rotary driving member 4 and the door 2. When the door 1 is opened, the rotary driving member 4 drives the transmission assembly 10, and the transmission assembly 10 drives the door 2 to move away from the hinge 7 along the width direction of the door 1, so that the door 2 does not interfere with the cabinet body on the side. When the door 1 is closed, the rotary driving member 4 drives the transmission assembly 10, and the transmission assembly 10 drives the door 2 to move towards the hinge 7 along the width direction of the door 1, so that the door 2 returns to its original position, ensuring that the door 2 does not interfere with the cabinet body around the refrigeration equipment.

[0068] In some embodiments, as Figure 2 and Figure 3 shown, the trigger 3 includes a displacement sensor, and the displacement sensor is used to detect the rotation direction of the door 1 to obtain the opening and closing signal.

[0069] 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 shaft of the hinge 7, and the angular displacement sensor can detect the rotation direction and rotation angle of the door 1 around the hinge shaft.

[0070] 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 states of the cabinet door 1, the opening and closing signals are 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 rotation driving member 4, and the rotation driving member 4 controls the transmission assembly 10 to drive 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 rotation driving member 4, and the rotation driving member 4 controls the transmission assembly 10 to drive the cabinet door 2 to move closer to the hinge 7 in the width direction of the cabinet door 1.

[0071] Furthermore, as the opening or closing amplitude of the cabinet door 1 is different, the displacement sensor can also obtain the rotation angle of the cabinet door 1. The rotation driving member 4 can determine the preset value of the movement of the cabinet door 2 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 rotation stroke of the output end of the rotation driving member 4 is determined, and then the transmission assembly 10 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 rotation stroke of the output end of the rotation driving member 4 is determined, and then the transmission assembly 10 drives the cabinet door 2 to move a preset distance closer to the hinge 7 to avoid interference between the cabinet door 2 and the external cabinet body, and finally, the cabinet door 2 is reset.

[0072] 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, which not only avoids interference but also ensures the beauty and reliability of the movement process of the cabinet door 2 relative to the cabinet door 1.

[0073] In some embodiments, as Figure 1 and Figure 3 shown, the trigger member 3 includes a push-button switch, and the push-button switch is used to receive 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.

[0074] 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 the push-button switch controls the opening mechanism to open or close the cabinet door 1 when it is triggered.

[0075] Generally, built-in refrigerators are designed without handles, using a pressure opening system or a hidden notch to replace the traditional handle. Alternatively, a push-button switch can also be used to control the opening and closing of the door 1 of the built-in refrigerator. The push-button switch in this embodiment is provided on the cabinet door of the refrigerator and is used to control the opening and closing of the 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 signals of the door 1 to the rotary drive member 4, and the rotary drive member 4 controls the transmission assembly 10 to drive the cabinet door 2 to move along the width direction of the door 1.

[0076] Specifically, after the push-button switch receives the input instruction to open the door 1, the push-button switch feeds back the opening signal to the door opening mechanism and the rotary drive member 4. The door opening mechanism drives the door 1 to open. At the same time, the rotary drive member 4 controls the transmission assembly 10 to drive the cabinet door 2 to move along the width direction of the door 1 away from the hinge 7, so as to ensure that when the door 1 is opened, the cabinet door 2 does not interfere with the surrounding parts.

[0077] After the push-button switch receives the input instruction to close the door 1, the push-button switch feeds back the closing signal to the door opening mechanism and the rotary drive member 4. The door opening mechanism drives the door 1 to close. At the same time, the rotary drive member 4 controls the transmission assembly 10 to drive the cabinet door 2 to move along the width direction of the door 1 towards the hinge 7, so as to ensure that when the 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 door 1 to ensure the aesthetics of the cabinet door 2.

[0078] In this embodiment, by setting the trigger member 3 as a push-button switch, the push-button switch can not only control the opening and closing of the door 1 by the door opening mechanism, but also feed back the opening and closing signals of the door 1 to the rotary drive member 4, so that the rotary drive member 4 controls the transmission assembly 10 to drive the cabinet door 2 to move along the width direction of the door 1, enabling the cabinet door 2 to open and close synchronously with the door 1 while avoiding the surrounding cabinet body of the cabinet door 2 to prevent interference with the surrounding cabinet body, ensuring the synchronism and aesthetics of the opening and closing of the door 1 and the cabinet door 2.

[0079] In some embodiments, as Figure 2 and Figure 3 shown, the transmission assembly 10 includes a gear 101 and a rack 102. The gear 101 and the rack 102 are meshed. The gear 101 is connected to the output end of the rotary drive member 4, and the rack 102 extends along the width direction and is connected to the cabinet door 2.

[0080] It is understandable that the gear 101 of this embodiment is provided on the cabinet door 1, the rack 102 is provided on the cabinet door 2, the rotary driving member 4 transmits the rotation to the gear 101, and based on the meshing of the gear 101 and the rack 102, the gear 101 transmits the rotation to the rack 102, which is converted into the linear motion of the rack 102, thereby driving the linear movement of the cabinet door 2. The gear 101 and the rack 102 of this embodiment realize the conversion from rotary motion to linear motion through a simple structure, and the structure is compact and easy to implement.

[0081] In some embodiments, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 shown, the sliding door mechanism further includes: a sliding module 5.

[0082] The sliding module 5 is configured to be provided 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.

[0083] It is understandable that due to the self-weight of the cabinet door 2, the cabinet door 2 may vibrate or tilt during the process of moving relative to the cabinet door 1. The sliding module 5 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.

[0084] 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 cabinet door 1, and the second sliding member can be installed on the cabinet door 2. It is also possible to install the first sliding member on the cabinet door 2 and the second sliding member on the cabinet door 1. The sliding module 5 realizes the relative movement between the cabinet door 1 and the cabinet door 2 through the relative sliding of the first sliding member and the second sliding member.

[0085] In some embodiments, such 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 cabinet 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.

[0086] 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.

[0087] The moving member can move along the extension 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. Moreover, 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 cabinet door 1.

[0088] Meanwhile, the detachable connection between the moving part 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.

[0089] Optionally, the detachable connection between the moving part and the cabinet door 2 can be achieved through fasteners, snap connections, or magnetic connections.

[0090] In some embodiments, as Figure 5 and Figure 6 shown, there are at least two sets of sliding modules 5. One end of the transmission component 10 is connected to the rotary driving member 4, and the other end is connected to the moving part of one of the at least two sets of sliding modules 5 to drive the moving part to move along the slide rail 51.

[0091] It can be understood that there can be multiple sets of sliding modules 5. One set of sliding modules 5 is used to connect to the transmission component 10 so that the rotary driving member 4 can control the transmission component 10 to drive the moving part to move along the slide rail 51, and further enable the rotary driving member 4 to control the transmission component 10 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 rotary driving member 4 serves as an active driving mechanism to achieve the cooperative design of the rotary driving member 4 and the sliding module 5. For cooperative guiding, 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, 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.

[0092] Specifically, in this embodiment, there are four sets of sliding modules 5. Two sets of 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, among the two sets of sliding modules 5 located at the upper end, the set closer to the hinge 7 is connected to the rotary driving member 4. The remaining three sets of sliding modules 5 are distributed in the remaining triangles of the box door 1. The slide rails 51 in the four sets of sliding modules 5 are arranged in parallel.

[0093] 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.

[0094] In some embodiments, as Figure 7 and Figure 8As shown, the moving member includes a sliding member 52 and a hanging member 53; the sliding member 52 is movably disposed on the slide rail 51 in the width direction, and the hanging member 53 is configured to be connected to the cabinet door 2 and is hung on the sliding member 52.

[0095] It can be understood 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, and the hanging member 53 is configured to be detachably connected to the cabinet door 2.

[0096] Further, the sliding member 52 of this embodiment includes a sliding body 521 and an adapter seat 522. The sliding body 521 and the adapter seat 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 seat 522, and the first card slot 5221 is used to hang 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 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.

[0097] Optionally, as Figure 7 shown, the sliding module 5 is an active driving mechanism, and the sliding module 5 is connected to the transmission component 10. In this embodiment, a rack 102 is fixedly connected to the sliding body 521, the rack 102 is meshed with a gear 101, and the output end of the rotary driving member 4 is connected to the gear 101, so that the rotary driving member 4 can control the transmission component 10 to drive the movement of the sliding body 521.

[0098] In some embodiments, as Figures 7 to 11 shown, the hanging member 53 includes a fixed seat 531 and a hanging part 532; the fixed seat 531 is configured to be connected to the cabinet door 2, and the hanging part 532 is adjustably disposed on the fixed seat 531 in the vertical direction or the horizontal direction, and the hanging part 532 is hung on the sliding member 52.

[0099] It can be understood that a slight adjustment in the vertical direction or the horizontal direction can be realized between the hanging part 532 and the fixed seat 531. Thus, by adjusting the relative position between the hanging part 532 and the fixed seat 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 the slight deviation in installation or manufacturing through fine adjustment, ensuring the aesthetic appearance of the installation of the box door 1 and the cabinet door 2.

[0100] 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 member 532; the hanging member 532 is slidably arranged in the installation groove, and a first clamping joint 5321 is formed on the hanging member 532 to adjust the relative position between the cabinet door 2 and the box door 1 by adjusting the position of the hanging member 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.

[0101] Specifically, the first clamping joint 5321 is a U-shaped downward hook that can pass through the notch and slide into the first clamping groove 5221. A first rectangular hole extending in the up and down direction is provided on the hanging member 532. The fixing base 531 is provided with two installation holes and an installation groove extending left and right between the two installation holes. A second rectangular hole extending in the left and right direction is provided on the side wall of the installation groove. The hanging member 532 can slide in the installation groove. By controlling the position of the hanging member 532 in the installation groove, the hanging member 532 can move up and down relative to the fixing base 531. Screws can be arranged to pass through the first rectangular hole on the installation groove and the second rectangular hole on the hanging member 532 to form a hanging member 532 that can be adjusted in both the up and down and left and right directions. And through the relative position between the installation holes of the fixing base 531 and the cabinet door 2, the position of the fixing base 531 and the cabinet door 2 can be adjusted in the up and down, left and right directions.

[0102] As Figure 10 and Figure 11 shown, the process of installing the hanging member 53 on the cabinet door 2 is as follows:

[0103] Insert the hanging member 532 into the installation groove of the fixing base 531. Use screws to pass through the second rectangular hole, the first rectangular hole and the cabinet door 2 to connect the fixing base 531 as a whole to the cabinet door 2. Hang the first clamping joint 5321 on the hanging member 532 connected in the first clamping groove 5221 to complete the connection between the hanging member 532 and the adapter base 522. Then, by observing the positional relationship between the cabinet door 2 and the box door 1, check whether there is any 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 screws 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, the fixing base 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 installation holes on both sides of the fixing base 531 and the cabinet door 2 to further fix the cabinet door 2 and the fixing base 531 to keep its position stable. Through the above method, not only can the position of the fixing base 531 be finely adjusted, but also it can be ensured that all fixings are firm, guaranteeing the accurate positional relationship between the cabinet door 2 and the box door 1.

[0104] In the second aspect, as Figure 1As shown in the figure, an embodiment of the present utility model further provides a door assembly, including: a box door 1, a cabinet door 2, and a sliding door mechanism.

[0105] The box door 1 is configured to be rotatably disposed on the box body 6 of the refrigeration device to open or close the storage compartment inside the box body 6; the cabinet door 2 is movably disposed 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 above.

[0106] Wherein, the thickness of the box door 1 is 18 - 60 mm. For example, the thickness of the box 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.

[0107] Specifically, since the door assembly includes a sliding door mechanism, and the specific structure of the sliding door mechanism refers to the above embodiment, the door assembly 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.

[0108] It can be understood that the door assembly in the present utility model can be applied to household appliances, such as a refrigerator. During the opening or closing process of the box door 1, the sliding door mechanism drives the cabinet door 2 to move relative to the box door 1.

[0109] For the door assembly shown in this embodiment, by rotatably connecting the box door 1 to the box body 6, movably disposing the cabinet door 2 on the outside of the box door 1 along the width direction of the box door 1, and using the sliding door mechanism to connect the box door 1 and the cabinet door 2, during the opening or closing process of the sliding door mechanism, controlling the cabinet door 2 to move relative to the box door 1, so that the box door 1 can avoid the side cabinet body during the opening and closing process, thereby avoiding the interference between the cabinet door 2 and the outside when the box door 1 rotates, and meeting the use requirements of users in different scenarios.

[0110] Specifically, during the movement of the cabinet door 2 relative to the box door 1, the cabinet door 2 can move left and right relative to the box door 1 along the width direction.

[0111] Such a design not only improves the convenience of use, but also can avoid possible damage to the door assembly during use. At the same time, this design also enables the refrigeration device to better integrate into the home environment, achieving the effects of overall beauty and sealing.

[0112] In some embodiments, as Figure 1 、 Figure 2 and Figure 3 shown, the door assembly and the box body 6 are configured to be disposed in the accommodation space between the first cabinet body 8 and the second cabinet body 9.

[0113] During the opening or closing process of the cabinet door 1, the rotary driving member 4 is used to drive the transmission assembly 10 to change the position of the cabinet door 2 on the cabinet door 1, so that the cabinet door 2 avoids the side wall of the first cabinet body 8 or the second cabinet body 9.

[0114] It can be understood 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 cabinet body 6 to be integrally embedded in the cabinet body. During the process of the cabinet 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 on the cabinet door 1 to move a preset distance in a direction away from or close to the cabinet body 6, so that the cabinet door 2 avoids the side walls of the first cabinet body 8 and the second cabinet body 9.

[0115] During the process of the cabinet door 1 passing through the opening to control the opening or closing of the accommodation space, the rotary driving member 4 drives the transmission assembly 10 to drive the cabinet door 2 on the cabinet door 1 to move in a direction away from or close to the cabinet body 6, and can also control 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 cabinet door 1 can be smoothly opened or closed without colliding or jamming with the side wall of the cabinet body.

[0116] For example, during the opening process of the cabinet door 1, the sliding door mechanism drives the cabinet door 2 to move a preset distance along the cabinet 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, so that the cabinet door 1 can be fully opened, facilitating users to access items.

[0117] Similarly, during the closing process of the cabinet door 1, the sliding door mechanism drives the cabinet door 2 to move a preset distance along the cabinet 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, so that the cabinet door 1 can be fully closed, maintaining the overall aesthetics and sealing performance.

[0118] In some embodiments, as Figure 2 and Figure 3 shown, the cabinet door 1 is rotatably connected to the cabinet body 6 through the hinge 7; the cabinet door 2 can move between a first position and a second position along the width direction relative to the cabinet door 1.

[0119] When the cabinet door 2 is in the first position, the cabinet door 1 closes the storage room, and the side of the cabinet door 2 facing the hinge 7 is arranged close to the hinge 7.

[0120] 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 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.

[0121] It is understandable that the interior of the storage compartment is used to store items to be refrigerated or frozen. When the door 1 of the compartment closes the storage compartment, the door 1 of the compartment is in a closed state. 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 door 1 of the compartment are flush. At this time, the cabinet door 2 can completely block the door 1 of the compartment, ensuring that the door body of the accommodation space exposed by the refrigeration device is consistent with the surrounding first cabinet 8 and second cabinet 9 in appearance.

[0122] When the door 1 of the compartment opens the storage compartment, the door 1 of the compartment is in an open state. 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 door 1 of the compartment are misaligned, and a gap is formed that can accommodate the side of the first cabinet 8 or the second cabinet 9, so as to avoid collision or interference between the cabinet door 2 and the first cabinet 8 or the second cabinet 9 caused by the opening of the door 1 of the compartment.

[0123] In some embodiments, as Figure 5 shown, the door body assembly is provided with the above sliding door mechanism. The door 1 of the compartment is provided with a groove 11, and the sliding module 5 is arranged in the groove 11.

[0124] The door body assembly further includes a decorative member; the decorative member is used to cover the notch end of the groove 11.

[0125] It is understandable that the sliding module 5 is arranged in the groove 11, which can enable the door 1 of the compartment to form a stable cooperation with the sliding module 5 during the opening and closing processes, reduce the overall thickness of the door 1 of the compartment and the cabinet door 2, and furthermore, the sliding module 5 is hidden in the groove 11. When the cabinet door 2 moves relative to the door 1 of the compartment, the user can only observe the movement of the cabinet door 2 relative to the door 1 of the compartment and cannot see the sliding of the sliding module 5, enhancing the aesthetics and consistency of the movement process of the cabinet door 2.

[0126] In this embodiment, four grooves 11 are provided. The four grooves 11 are respectively arranged at the four corners of the door 1 of the compartment. The groove 11 is provided with a plurality of threaded holes, and the slide rail 51 has through holes corresponding to the threaded holes in the groove 11. In this way, the slide rail 51 can be fixed in the groove 11 by setting bolts on the slide rail 51.

[0127] When the refrigeration device is fully embedded, it is necessary to set the cabinet door 2 on the outside of the door 1 of the compartment. The sliding module 5 is arranged in the groove 11 on the door 1 of the compartment, which can ensure the aesthetics of the cabinet door 2 when the door 1 of the compartment and the cabinet door 2 move relative to each other.

[0128] When the refrigeration device is flush-mounted, it is not necessary to install the cabinet door 2 on the outside of the door 1 of the compartment. In order to ensure the aesthetics of the outside of the door 1 of the compartment, the decorative member is covered on the groove 11 to ensure the aesthetics of the appearance of the refrigeration device.

[0129] Specifically, the decorative member can be a decorative cover having the same material and color as the cabinet door 1.

[0130] The user can choose whether to install the cabinet door 2 according to actual needs and select a suitable connection method according to different application scenarios.

[0131] In a third aspect, as Figure 1 , Figure 2 and Figure 3 shown, 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 provided on the box body 6 to open or close the storage compartment.

[0132] 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.

[0133] It can be understood that during the opening process of the box door 1, the sliding door mechanism driving the cabinet door 2 to move away from the hinge 7 can avoid interference between the cabinet door 2 and the cabinet body 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 body around the refrigeration device when closed.

[0134] 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 body 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.

[0135] 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.

[0136] 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.
