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.

[0079] The following will combine Figures 1 to 11 , and through specific embodiments and their application scenarios, the sliding door mechanism, door body assembly, and refrigeration equipment provided by the embodiments of the present utility model will be described in detail.

[0080] In the first aspect, as Figure 1 shown, the embodiments of the present utility model provide a sliding door mechanism, which is 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 guide member 3, a sliding member 4, a connecting rod assembly 5, and a driving member 6.

[0081] The guide member 3 is configured to be arranged on the box door 1. A guiding structure 31 is provided on the guide member 3. The sliding member 4 is configured to be arranged on the cabinet door 2. The sliding member 4 is movably arranged on the guide member 3 along the width direction of the box door 1.

[0082] The connecting rod assembly 5 is movably arranged on the guiding structure 31 and can be structurally deformed under the guidance of the guiding structure 31. The second end of the connecting rod assembly 5 is movably connected to the sliding member 4.

[0083] The driving member 6 is arranged on the box body 9 and is movably connected to the first end of the connecting rod assembly 5 to drive the connecting rod assembly 5 to be structurally deformed during the opening and closing of the box door 1, and then the connecting rod assembly 5 drives the sliding member 4 to drive the cabinet door 2 to move along the width direction.

[0084] 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.

[0085] The guiding structure 31 can ensure that the connecting rod assembly 5 moves along a predetermined path or direction, prevent it from deviating from the predetermined trajectory, and can guide the structural deformation of the connecting rod assembly 5, and then drive the sliding member 4 to move along the width direction of the box door 1.

[0086] Optionally, the guiding structure 31 can guide the connecting rod assembly 5 to move along the tooth profile of the sprocket through the cooperation of the sprocket and the chain. The guiding structure 31 can also guide the connecting rod assembly 5 to move along the cross-section of the guide rail through the cooperation of the slider 42 and the guide rail.

[0087] Through the structural deformation of the connecting rod assembly 5 itself, the distance between the second end of the connecting rod assembly 5 and the hinge 10 is changed, thereby driving the change in the distance between the sliding member 4 and the hinge 10. Further, the change in the distance between the cabinet door 2 connected to the sliding member 4 and the hinge 10 is realized.

[0088] Optionally, the connecting rod assembly 5 can be a parallel four-bar linkage or a crank-rocker mechanism.

[0089] 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 a guiding structure 31 is arranged on the guiding member 3. The guiding structure 31 can guide the connecting rod assembly 5 to undergo structural deformation, and the second end of the connecting rod assembly 5 is movably connected to the sliding member 4. When the cabinet door 1 is opened, the driving member 6 drives the first end of the connecting rod assembly 5, the connecting rod assembly 5 undergoes structural deformation, and the second end of the connecting rod assembly 5 pulls the sliding member 4 to move away from the hinge 10, thereby driving the cabinet door 2 to move away from the hinge 10 along the width direction of the cabinet door 1, so that the cabinet door 2 does not interfere with the side cabinet; when the cabinet door 1 is closed, the driving member 6 drives the first end of the connecting rod assembly 5, the connecting rod assembly 5 undergoes structural deformation, and the second end of the connecting rod assembly 5 pulls the sliding member 4 to move towards the hinge 10, thereby driving the cabinet door 2 to move towards the hinge 10 along the width direction of the cabinet door 1, so that the cabinet door 2 returns to its original position, ensuring that the cabinet door 2 does not interfere with the cabinets around the refrigeration equipment.

[0090] In some embodiments, as Figure 1 shown, the connecting rod assembly 5 includes: a first connecting rod 51 and a second connecting rod 52.

[0091] The driving member 6 is rotatably connected to the first end of the first connecting rod 51, and the second end of the first connecting rod 51 and the first end of the second connecting rod 52 are rotatably connected through a first hinge shaft 53; the first hinge shaft 53 is arranged on the guiding structure 31 and moves along the thickness direction of the cabinet door 2 under the guidance of the guiding structure 31; the second end of the second connecting rod 52 is rotatably connected to the sliding member 4.

[0092] The driving member 6 is used to drive the first end of the first connecting rod 51 to move along the width direction, and the first connecting rod 51 is used to drive the first hinge shaft 53 to move along the thickness direction to change the included angle between the first connecting rod 51 and the second connecting rod 52, and then the second connecting rod 52 drives the sliding member 4 to move along the direction opposite to the driving direction of the driving member 6.

[0093] It is understandable that the driving member 6 provides a driving force to the first end of the first link 51, and the guiding structure 31 can restrict the movement path of the first hinge shaft 53, so that the first hinge shaft 53 can only move along the thickness direction of the cabinet door 1, thereby changing the included angle between the first link 51 and the second link 52, and thus enabling the second link 52 to move along the width direction.

[0094] During the process of the cabinet door 1 opening the cabinet body 9, the driving member 6 drives the first end of the first link 51 to move along the width direction towards the hinge 10. The first link 51 drives the first hinge shaft 53 to move along the thickness direction towards the sliding member 4, increasing the included angle between the first link 51 and the second link 52, pushing the second link 52 to move away from the hinge 10, and further driving the sliding member 4 to move along the width direction away from the hinge 10, so that the cabinet door 2 does not interfere with the side cabinet body.

[0095] During the process of the cabinet door 1 closing the cabinet body 9, the driving member 6 drives the first end of the first link 51 to move along the width direction away from the hinge 10. The first link 51 drives the first hinge shaft 53 to move along the thickness direction away from the sliding member 4, decreasing the included angle between the first link 51 and the second link 52, pushing the second link 52 to move towards the hinge 10, and further driving the sliding member 4 to move along the width direction towards the hinge 10, so that the cabinet door 2 returns to its original position, ensuring that the cabinet door 2 does not interfere with the cabinet body around the refrigeration equipment.

[0096] In this embodiment, by providing the first link 51, the second link 52 and the first hinge shaft 53 in the link assembly 5, and restricting the movement of the first hinge shaft 53 in the thickness direction, the included angle between the first link 51 and the second link 52 is changed, so that the second link 52 can drive the sliding member 4 to move along the width direction, realizing the movement of the cabinet door 2 relative to the cabinet door 1. The structure is simple and the volume is small.

[0097] In some embodiments, as Figure 1 shown, the driving member 6 includes: a linkage member.

[0098] The first end of the linkage member is configured to be rotatably disposed at a fixed position on the cabinet body 9 of the refrigeration equipment, and the second end of the linkage member is rotatably connected to the first end of the first link 51; the fixed position is disposed deviating from the hinge position between the cabinet door 1 and the cabinet body 9.

[0099] During the process of the cabinet door 1 opening the cabinet body 9, the linkage member is used to drive the first end of the first link 51 to move towards the side close to the hinge position, and the second link 52 drives the sliding member 4 to drive the cabinet door 2 to move towards the side away from the hinge position.

[0100] During the process of closing the cabinet door 1 to the cabinet body 9, the linkage is used to drive the first end of the first link 51 to move towards the side away from the hinge position, and the second link 52 drives the sliding member 4 to drive the cabinet door 2 to move towards the side close to the hinge position.

[0101] It can be understood that the first end of the linkage in this embodiment is rotatably arranged on the hinge 10. When the cabinet door 1 rotates relative to the cabinet body 9 around the hinge axis, the second end of the linkage rotates in a circular motion with the hinge axis as the center. Since the first end of the linkage is misaligned with the hinge axis, the distance between the second end of the linkage and the hinge 10 will change with the rotation of the linkage, thereby driving the link assembly 5 to move towards or away from the hinge 10 along the width direction of the cabinet door 1.

[0102] During the process of opening the cabinet door 1 from the cabinet body 9, as the cabinet door 1 rotates, the cabinet door 1 drives the linkage to rotate. The second end of the linkage drives the first end of the first link 51 to move towards the side close to the hinge position, and the second end of the second link 52 drives the sliding member 4 to move towards the side away from the hinge position, thereby causing the cabinet door 2 to move towards the side away from the hinge position.

[0103] During the process of closing the cabinet door 1 to the cabinet body 9, as the cabinet door 1 rotates, the cabinet door 1 drives the linkage to rotate. The second end of the linkage drives the first end of the first link 51 to move towards the side away from the hinge position, and the second end of the second link 52 drives the sliding member 4 to move towards the side away from the hinge position, thereby causing the cabinet door 2 to move towards the side close to the hinge position.

[0104] In this embodiment, by setting the first end of the linkage to deviate from the hinge position between the cabinet door 1 and the cabinet body 9, the second end of the linkage can drive the first end of the first link 51, enabling the second link 52 to drive the sliding member 4 to move in the width direction. The opening and closing of the cabinet door 1 can control the transmission of the linkage driving the link assembly 5, enabling the sliding member 4 to drive the cabinet door 2 to move in the width direction without an additional driving device, and enabling the movement of the cabinet door 2 relative to the cabinet door 1 to be synchronized with the opening and closing of the cabinet door 1.

[0105] In some embodiments, as Figure 2 shown, the guiding structure 31 includes: a first limiting groove 311.

[0106] The first limiting groove 311 extends in the thickness direction.

[0107] The first hinge shaft 53 is inserted into the first limiting groove 311 and can move along the extending direction of the first limiting groove 311.

[0108] It is understandable that the first limiting groove 311 is used to limit the first hinge shaft 53, so that the first hinge shaft 53 can only move in the thickness direction. Furthermore, the angle between the first connecting rod 51 and the second connecting rod 52 respectively connected to the first hinge shaft 53 can change, and the moving directions of the second end of the first connecting rod 51 and the second end of the second connecting rod 52 are opposite.

[0109] The first limiting groove 311 of this embodiment can guide the moving direction of the first hinge shaft 53. Moreover, the first limiting groove 311 can be directly opened on the upper surface of the guiding member 3 without occupying additional space, ensuring the compactness of the structure of the sliding door mechanism.

[0110] In some embodiments, as Figure 2 shown, the guiding structure 31 further includes: a second limiting groove 312.

[0111] The second limiting groove 312 extends in the width direction and communicates with the first limiting groove 311.

[0112] The driving member 6 is rotatably connected to the first end of the first connecting rod 51 through a second hinge shaft 54, and the second end of the second connecting rod 52 is rotatably connected to the sliding member 4 through a third hinge shaft 55; the second hinge shaft 54 and the third hinge shaft 55 are respectively inserted into the second limiting groove 312 and can move along the extending direction of the second limiting groove 312;

[0113] wherein, the second hinge shaft 54 and the third hinge shaft 55 are respectively arranged on both sides of the first limiting groove 311.

[0114] It is understandable that the second limiting groove 312 is used to limit the second hinge shaft 54 and the third hinge shaft 55, so that the second hinge shaft 54 and the third hinge shaft 55 can only move in the width direction. Furthermore, the second connecting rod 52 can drive the sliding member 4 to move in the width direction. The second limiting groove 312 of this embodiment ensures that the moving direction of the sliding member 4 will not deviate, ensuring the reliability and stability of the moving direction of the sliding member 4, and thus ensuring the reliability of the movement of the cabinet door 2 along the width direction of the box door 1.

[0115] In some embodiments, as Figure 1 shown, the sliding door mechanism further includes: an elastic member 7.

[0116] The elastic member 7 is arranged between the guiding member 3 and the sliding member 4.

[0117] When the connecting rod assembly 5 drives the sliding member 4 to move towards the side away from the hinge position, the sliding member 4 compresses the elastic member 7 during the process of driving the cabinet door 2 to move.

[0118] When the connecting rod assembly 5 drives the sliding member 4 to move towards the side close to the hinge position, the elastic member 7 drives the sliding member 4 to drive the cabinet door 2 to move towards the hinge position.

[0119] Among them, the hinge position is located between the cabinet door 1 and the cabinet body 9, and the cabinet door 1 is rotatably arranged on the cabinet body 9 based on the hinge position.

[0120] It can be understood that when the link assembly 5 drives the sliding member 4 to move towards the side away from the hinge position, the elastic member 7 is compressed in the direction away from the hinge 10 to accumulate elastic potential energy.

[0121] When the link assembly 5 drives the sliding member 4 to move towards the side close to the hinge position, the elastic potential energy of the elastic member 7 is released, and the elastic force of the elastic member 7 acts on the sliding member 4 to drive the sliding member 4 close to the hinge position.

[0122] Specifically, the elastic member 7 can be an elastic sheet, an elastic block, or a spring.

[0123] In this embodiment, by arranging the elastic member 7 in the sliding door mechanism, based on the elastic deformation of the elastic member 7, it can be ensured that the movement of the sliding member 4 relative to the guide member 3 is more stable and reliable.

[0124] In some embodiments, as Figure 2 shown, the guide member 3 includes: a fixing plate 32 and a sliding groove 33.

[0125] The fixing plate 32 is configured to be arranged on the cabinet door 1.

[0126] The sliding groove 33 is arranged on the fixing plate 32 and extends along the width direction, and at least part of the sliding member 4 is movably arranged in the sliding groove 33 along the width direction.

[0127] It can be understood that the fixing plate 32 in this embodiment is used for fixedly connecting with the cabinet door 1, and the sliding groove 33 is used for guiding the movement of the sliding member 4 along the width direction of the cabinet door 1. Based on the sliding fit between the sliding member 4 and the sliding groove 33, it is ensured that the sliding member 4 can move stably and reliably along the width direction of the cabinet door 1.

[0128] In some embodiments, as Figure 2 and Figure 3 shown, the guide member 3 further includes a sliding sleeve 34, and the sliding sleeve 34 is arranged at one end of the sliding groove 33 away from the hinge position.

[0129] The sliding member 4 includes a guide rod 41 and a slider 42. The guide rod 41 passes through the sliding sleeve 34, and a sliding contact 45 is arranged on the guide rod 41. The sliding contact 45 is movably arranged in the sliding groove 33 along the width direction; the slider 42 is connected with the guide rod 41 and is configured to be connected with the cabinet door 2.

[0130] Among them, the elastic member 7 is arranged between the sliding sleeve 34 and the sliding contact 45.

[0131] It is understandable that the sliding groove 33 in this embodiment is arc-shaped to be adapted to the outer wall of the guide rod 41. The sliding sleeve 34 is used to guide the movement of the guide rod 41 relative to the sliding groove 33. Moreover, as the sliding member 4 moves on the sliding groove 33, the sliding contact 45 also moves accordingly. The sliding sleeve 34 is fixedly arranged relative to the fixed plate 32, and the elastic member 7 is limited between the sliding sleeve 34 and the sliding contact 45. When the guide rod 41 moves toward the side away from the hinge 10, the sliding contact 45 moves toward the sliding sleeve 34, causing the elastic member 7 between the sliding sleeve 34 and the sliding contact 45 to be compressed. When the guide rod 41 moves toward the side close to the hinge 10, the elastic member 7 releases elastic potential energy and elongates, and the sliding contact 45 moves in the direction away from the sliding sleeve 34. The sliding sleeve 34 and the sliding contact 45 restrain the elastic member 7 from both sides to ensure the reliability of the compression and elongation of the elastic member 7.

[0132] Moreover, one end of the slider 42 is connected to the guide rod 41, and the other end is connected to the cabinet door 2, so that when the guide rod 41 moves along the width direction of the cabinet door 1, the sliding can drive the cabinet door 2 to move along the width direction of the cabinet door 1.

[0133] In some embodiments, such as Figure 1 、 Figure 2 and Figure 3 shown, the elastic member 7 includes a spring. The spring is sleeved on the outer side of the guide rod 41 and is limited between the sliding sleeve 34 and the sliding contact 45.

[0134] It is understandable that when the elastic member 7 is arranged as a spring, the hollow structure of the spring enables the spring to be sleeved on the outer wall of the guide rod 41. And in the length direction of the guide rod 41, the state of the spring changes in terms of compression and elongation. Moreover, the sliding sleeve 34 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 simple and compact when the cabinet door 2 is reset relative to the cabinet body 1, with a small volume, saving the installation space of the cabinet door 2.

[0135] In some embodiments, such as Figure 3 shown, the sliding member 4 further includes: a first connecting arm 43 and a second connecting arm 44.

[0136] 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.

[0137] The sliding sleeve 34 and the sliding contact 45 are located between the first connecting arm 43 and the second connecting arm 44.

[0138] 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 cabinet door 1, it is easier to fit along the width direction.

[0139] Furthermore, in this embodiment, the slider 42 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 32 is installed at the top of the cabinet door 1, and the cabinet door 2 and the cabinet door 1 can be parallel and fitted, ensuring the flatness when the cabinet door 2 is installed on the cabinet door 1. And it is beneficial for the cabinet door 2 to move along the cabinet door 1.

[0140] In some embodiments, as Figures 5 to 10 shown, the sliding door mechanism further includes: a sliding module 8.

[0141] The sliding module 8 is configured to be arranged between the cabinet door 1 and the cabinet door 2, and the sliding module 8 is used to guide the cabinet door 2 to move relative to the cabinet door 1 along the width direction.

[0142] 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 cabinet 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 cabinet door 1.

[0143] 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 along the width direction. The first sliding member 82 can be installed on the cabinet door 1 and the second sliding member 82 can be installed on the cabinet door 2, or the first sliding member 82 can be installed on the cabinet door 2 and the second sliding member 82 can be installed on the cabinet door 1. The sliding module 8 realizes the relative movement between the cabinet door 1 and the cabinet door 2 through the relative sliding of the first sliding member 82 and the second sliding member 82.

[0144] In some embodiments, as Figure 6 and Figure 7 shown, the sliding module 8 includes: a slide rail 81 and a moving member.

[0145] The slide rail 81 is configured to be arranged on the cabinet door 1 and extend along the width direction.

[0146] The moving member is movably arranged on the slide rail 81 along the width direction, and the moving member is configured to be detachably connected to the cabinet door 2.

[0147] It is understandable that the slide rail 81 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 81 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.

[0148] The moving part can move along the extension direction of the slide rail 81. Based on the guiding and supporting functions of the slide rail 81, the moving part can move stably and reliably along the slide rail 81. Moreover, due to the high rigidity of the slide rail 81, a high straightness can be provided for the moving part, so that the cabinet door 2 can move stably and reliably along the width direction of the box door 1.

[0149] 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.

[0150] Optionally, the detachable connection between the moving part and the cabinet door 2 can be achieved through fasteners, or through snap connection, or through magnetic connection.

[0151] In some embodiments, as Figure 5 shown, there are at least two sets of sliding modules 8. The first end of the link assembly 5 is connected to the driving part 6, the second end of the link assembly 5 is connected to the sliding part 4, and the sliding part 4 is connected to the moving part of one of the at least two sets of sliding modules 8.

[0152] Among them, the link assembly 5 is used to drive the sliding part 4 to drive the moving part to move along the slide rail 81.

[0153] It can be understood that there can be multiple sets of sliding modules 8. One set of the sliding modules 8 is used to connect with the sliding part 4, so that the driving part 6 can control the link assembly 5 to drive the moving part to move along the slide rail 81. Furthermore, the driving assembly can control the link assembly 5 to drive the cabinet door 2 to move relative to the box door 1 along the extension direction of the slide rail 81. The sliding module 8 connected to the sliding part 4 serves as the active driving mechanism, realizing the cooperative design of the driving part 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 the movement, avoiding interference with the side wall of the cabinet body. Moreover, the remaining multiple sets of sliding modules 8 serve as passive guiding mechanisms. Through the cooperation of the multiple sets of sliding modules 8, the cabinet door 2 can move smoothly and stably relative to the box door 1, improving the convenience and reliability of use, and being conducive to achieving precise control and smooth movement of the cabinet door 2.

[0154] Specifically, there are four sets of sliding modules 8 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 part 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.

[0155] Correspondingly, among the three sets of driven sliding modules 8, the sliding modules 8 located at the upper end of the cabinet door 1 have the same structure as the sliding modules 8 at the lower end of the cabinet door 1 and are symmetrically arranged on the cabinet door 1.

[0156] In some embodiments, as Figure 6 and Figure 7 shown, the moving part includes a sliding part 82 and a hanging part 83; the sliding part 82 is movably arranged on the slide rail 81 along the width direction, and the hanging part 83 is configured to be connected to the cabinet door 2 and is hung on the sliding part 82.

[0157] It can be understood that the hanging part 83 is used to connect the sliding part 82 and the cabinet door 2 to realize the movement of the cabinet door 2 relative to the cabinet door 1 driven by the sliding part 82, and the hanging part 83 is configured to be detachably connected to the cabinet door 2.

[0158] Furthermore, the sliding part 82 of this embodiment includes a sliding body 821 and an adapter seat 822. The sliding body 821 and the adapter seat 822 are fixedly connected. A support frame 811 is provided on the slide rail 81. A round hole is provided on the support frame 811, and a ball is installed in the round hole. The sliding body 821 is in rolling contact with the slide rail 81 to move on the slide rail 81 along the width direction. A first card slot 8221 is provided on the adapter seat 822, and the first card slot 8221 is used to hang the hanging part 83 on the sliding body 821. The relative movement between the sliding body 821 and the slide rail 81 of this embodiment is rolling friction, so as to reduce the frictional force and improve the moving efficiency of the moving part. This design can accurately control the movement 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 cabinet door 1.

[0159] Optionally, as Figure 6 shown, the sliding module 8 is an active driving mechanism. The sliding module 8 is connected to the sliding part 4, the sliding part 4 is connected to the link assembly 5, and the driving part 6 is connected to the link assembly 5, so that the driving part 6 can control the link assembly 5 to drive the movement of the sliding body 821.

[0160] In some embodiments, as Figures 6 to 10 shown, the hanging part 83 includes a fixed seat 831 and a hanging member 832; the fixed seat 831 is configured to be connected to the cabinet door 2, and the hanging member 832 is adjustably arranged on the fixed seat 831 along the vertical direction or the horizontal direction, and the hanging member 832 is hung on the sliding part 82.

[0161] It can be understood that a slight adjustment in the vertical direction or the horizontal direction can be realized between the hanging member 832 and the fixed seat 831, so that the position deviation between the cabinet door 2 and the cabinet door 1 can be adjusted by adjusting the relative position between the hanging member 832 and the fixed seat 831, so that the cabinet door 1 and the cabinet door 2 can correct the slight deviation in installation or manufacturing through fine adjustment, ensuring the aesthetics of the installation of the cabinet door 1 and the cabinet door 2.

[0162] Specifically, the fixing base 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 fixing base 831 for accommodating the hanging member 832; the hanging member 832 is slidably arranged in the installation groove, and a first clamping joint 8321 is formed on the hanging member 832 to adjust the relative position between the cabinet door 2 and the box door 1 by adjusting the position of the hanging member 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.

[0163] Specifically, the first clamping joint 8321 is a downward U-shaped hook that can pass through the notch and slide into the first clamping groove 8221. A first rectangular hole extending in the up-down direction is provided on the hanging member 832, and the fixing base 831 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-right direction is provided on the side wall of the installation groove. The hanging member 832 can slide in the installation groove. By controlling the position of the hanging member 832 in the installation groove, the hanging member 832 can move up and down relative to the fixing base 831. Screws can be set to pass through the first rectangular hole on the installation groove and the second rectangular hole on the hanging member 832, and a hanging member 832 that can be adjusted in both the up-down and left-right directions can be formed. And through the relative position between the installation holes of the fixing base 831 and the cabinet door 2, the position of the fixing base 831 and the cabinet door 2 can be adjusted in the up-down, left-right directions.

[0164] As Figure 9 and Figure 10 shown, the process of installing the hanging member 83 on the cabinet door 2 is as follows:

[0165] Thread the hanging member 832 through the installation groove of the fixing base 831. Use screws to pass through the second rectangular hole, the first rectangular hole, and the cabinet door 2 to integrally connect the fixing base 831 to the cabinet door 2. Hang the first clamping joint 8321 on the hanging member 832 that has been connected into the first clamping groove 8221 to complete the connection between the hanging member 832 and the adapter base 822. 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 83 is separated from the cabinet door 2, and the position of the hanging member 83 is adjusted. For the cabinet door 2 and the fixing base 831, the hanging member 832 assembly, the position of the hanging member 832 is adjusted. If the positional relationship meets the requirements and no adjustment is needed, then use screws to pass through the installation holes on both sides of the fixing base 831 and the cabinet door 2 to further fix the cabinet door 2 and the fixing base 831 to keep its position stable. Through the above method, not only can the position of the fixing base 831 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.

[0166] In the second aspect, asFigure 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 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.

[0167] Among them, the thickness of the cabinet door 1 is 18-60mm, for example, the thickness of the cabinet door 1 can be 18mm, 25mm, 35mm, 50mm, 55mm or 60mm; the thickness of the cabinet door 2 is 12-26mm, for example, the thickness of the cabinet door 2 can be 12mm, 15mm, 20mm or 26mm; the cabinet door 2 can be a wooden door panel or a plastic door panel.

[0168] Specifically, since the door body assembly includes a sliding door mechanism, the specific structure of the sliding door mechanism refers to the above embodiment, and the door body assembly shown in this embodiment includes all the technical solutions of the above embodiment. Therefore, it has at least all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be repeated here one by one.

[0169] It is understandable that the door assembly of the present invention can be applied to household appliances, such as refrigerators. The sliding door mechanism drives the cabinet door 2 to move relative to the cabinet door 1 during the process of opening or closing the cabinet door 1.

[0170] For the door assembly shown in the present embodiment, the box door 1 is rotatably connected to the box body 9, and the cabinet door 2 is movably arranged on the outside of the box door 1 along the width direction of the box door 1, and the box door 1 and the cabinet door 2 are connected by a sliding door mechanism. During the opening or closing of the sliding door mechanism, the cabinet door 2 is controlled to move relative to the box door 1, so that the box door 1 can avoid the side cabinet during the opening and closing process, thereby avoiding interference between the cabinet door 2 and the outside when the box door 1 rotates, thereby meeting the user's usage requirements in different scenarios.

[0171] 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.

[0172] Such a design not only improves the convenience of use, but also avoids possible damage to the door assembly during use. At the same time, this design also allows the refrigeration equipment to be better integrated into the home environment, achieving an overall beautiful and sealed effect.

[0173] In the third aspect, Figure 4 and Figure 11 As shown, the embodiment of the utility model further provides a refrigeration device, comprising: a box body 9 and a door assembly as above, the box body 9 having a storage compartment, and the box door 1 is rotatably disposed on the box body 9 to open or close the storage compartment.

[0174] Specifically, since the refrigeration device includes a door body assembly, and the specific structure of the door body assembly refers to the above-mentioned embodiment, the refrigeration device shown in this embodiment includes all the technical solutions of the above-mentioned embodiment. Therefore, it has at least all the beneficial effects achieved by all the technical solutions of the above-mentioned embodiment, which will not be elaborated here one by one.

[0175] It is understandable that the box door 1 is used to open and close the storage compartment. When the refrigeration device is installed in a fully embedded manner, in order to keep the consistency between the refrigeration device 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.

[0176] The refrigeration device of this embodiment can install the cabinet door 2 on the box door 1 through a sliding door mechanism, so that when the refrigeration device is opened and closed, the interference between the cabinet door 2 and the cabinet bodies around the refrigeration device 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.

[0177] In some embodiments, as Figure 4 shown, the box body 9 is configured to be disposed in the accommodating space between the first cabinet body 11 and the second cabinet body 12.

[0178] 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.

[0179] It is understandable that an opening is provided on the outer side of the accommodating space between the first cabinet body 11 and the second cabinet body 12. This design enables the refrigeration device 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 accommodating space, the driving member 6 is configured to drive the cabinet door 2 on the box door 1 to move a preset distance 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.

[0180] During the process of the box door 1 passing through the opening to control the opening or closing of the accommodating space, the driving member 6 is configured to drive the cabinet door 2 on the box door 1 to move 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 possible damage to the door body 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.

[0181] In some embodiments, asFigure 4 As shown, the door 1 of the box is rotatably connected to the box body 9 through a hinge 10; the cabinet door 2 can move relative to the box door 1 between a first position and a second position in the width direction.

[0182] When the cabinet door 2 is in the first position, the box door 1 closes the storage compartment, and the side of the cabinet door 2 facing the hinge 10 is arranged close to the hinge 10.

[0183] 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.

[0184] 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.

[0185] 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 offset, and a gap is formed that can accommodate the side of the first cabinet body 11 or the second cabinet body 12, so as to avoid collision or interference between the cabinet door 2 and the first cabinet body 11 or the second cabinet body 12 caused by the opening of the box door 1.

[0186] 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.
