In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0079] The following is combined with Figures 1 to 12 This application describes a door assembly and a refrigeration device. The door assembly of this application can be applied to household appliances, such as refrigerators; however, it should be understood that the door assembly of this application can also be applied to dishwashers, washing machines, or any other suitable equipment.

[0080] In one embodiment of this application, such as Figures 1 to 3 As shown, the door assembly includes: a door 2, a door panel 3, and a transmission mechanism 5. The door 2 is rotatably connected to the appliance body 1 via a hinge 4, and the door 2 is adapted to open or close the storage space of the appliance body 1; the door panel 3 is slidably disposed on the outside of the door 2, and the transmission mechanism 5 drives the door panel 3 to move relative to the door 2 during the opening or closing of the door 2.

[0081] The transmission mechanism 5 may include transmission components such as connecting rods, gears, and racks. These components are connected to the door 2 and the door panel 3 through appropriate connection methods (such as bolt connection, welding, etc.). In this way, when the door 2 rotates, the transmission mechanism 5 can drive the door panel 3 to move along the door 2.

[0082] Specifically, such as Figure 1 As shown, during the opening of the door 2, the transmission mechanism 5 drives the door panel 3 to move away from the hinge 4 (moving to the left relative to the door 2), thus preventing the door panel 3 from interfering with objects on the side. During the closing of the door 2, the transmission mechanism 5 drives the door panel 3 to move closer to the hinge 4 (moving to the right relative to the door 2), thus ensuring that the door panel 3 avoids objects on the side when closed.

[0083] According to the door assembly of this application embodiment, the cabinet door 2 is rotatably connected to the electrical body 1, and the door panel 3 is slidably disposed on the outside of the cabinet door 2. The cabinet door 2 and the door panel 3 are connected by a transmission mechanism 5. During the opening or closing process, the transmission mechanism 5 controls the door panel 3 to move relative to the cabinet door 2, so that the cabinet door 2 can be offset from the side cabinet during the opening and closing process. This can avoid interference between the door panel 3 and the outside when the cabinet door 2 rotates, and can meet the user's usage needs in different scenarios.

[0084] It should be noted that during the movement of the door panel 3 relative to the box door 2, the door panel 3 can move left and right relative to the box door 2, or the door panel 3 can move up and down relative to the box door 2.

[0085] The movement relationship between door panel 3 and cabinet door 2 needs to be explained in detail. During the movement of door panel 3 relative to cabinet door 2, there are two main ways of movement: one is that door panel 3 can move left and right relative to cabinet door 2; the other is that door panel 3 can move up and down relative to cabinet door 2.

[0086] When door panel 3 moves left or right relative to door 2, door panel 3 remains unchanged in the vertical direction of door 2, but moves in the horizontal direction. This means that the position of door panel 3 changes as it moves left or right relative to door 2, while its vertical distance from door 2 remains constant.

[0087] When the door panel 3 moves up and down relative to the box door 2, the door panel 3 remains unchanged in the horizontal direction of the box door 2, but moves in the vertical direction. This means that the position of the door panel 3 changes as it moves up and down relative to the box door 2, while its horizontal distance from the box door 2 remains constant.

[0088] It should be noted that when door panel 3 moves left and right (or up and down) relative to door 2, this does not mean that the only way door panel 3 can move is left and right (or up and down) relative to door 2. In fact, within a certain error range, the way door panel 3 moves can be varied. For example, door panel 3 can move horizontally or vertically relative to door 2 within an error range of ±5°.

[0089] Furthermore, we need to clarify the relationship between door panel 3 and cabinet door 2. Their connection is not limited to simple left-right (or up-down) movement, but also includes various other possible relative movements. These movements may include slight vibrations, swaying, etc., which go beyond the scope of simple left-right (or up-down) movement.

[0090] In actual operation, the movement of door panel 3 cannot be perfectly precise in accordance with the predetermined direction and distance; there will always be a certain degree of error. Therefore, as long as this error is within an acceptable range, the movement of door panel 3 can be considered a valid movement.

[0091] Furthermore, the movement of door panel 3 can also be affected by external factors, such as wind and vibration. These factors may cause door panel 3 to make corresponding adjustments within a certain range to maintain its relative position with the cabinet door 2.

[0092] In the embodiments of this application, such as Figures 1 to 3 As shown, the door assembly and electrical body 1 are disposed within the installation space 100 formed between the first cabinet 11 and the second cabinet 12. An opening is provided on the outer side of the installation space 100, allowing the door assembly and electrical body 1 to be integrally embedded into the cabinet. During the process of the door 2 passing through the opening to control the opening or closing of the storage space, the transmission mechanism 5 is configured to drive the door panel 3 to move a predetermined distance away from or towards the hinge 4 on the door 2, so that the door panel 3 avoids the side walls of the first cabinet 11 and the second cabinet 12.

[0093] During the opening or closing of the storage space controlled by the door 2 through the opening, the transmission mechanism 5 is configured to drive the door panel 3 to move a preset distance away from or towards the hinge 4 on the door 2. This design is primarily to avoid interference between the door panel 3 and the side walls of the first cabinet 11 and the second cabinet 12. Through the movement of the preset distance, the door panel 3 can open or close smoothly without colliding with or getting stuck against the side walls of the cabinets.

[0094] For example, such as Figure 1 and Figure 2 As shown, during the opening of the cabinet door 2, the transmission mechanism 5 drives the door panel 3 to move a preset distance away from the hinge 4 along the cabinet door 2 (a preset distance to the left relative to the cabinet door 2). In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet 12, allowing the cabinet door 2 to be fully opened, making it convenient for users to store and retrieve items.

[0095] Similarly, during the closing process of the cabinet door 2, the transmission mechanism 5 drives the door panel 3 to move a preset distance along the cabinet door 2 towards the hinge 4 (a preset distance relative to the rightward movement of the cabinet door 2). In this way, the door panel 3 can smoothly avoid the side wall of the first cabinet 11, allowing the cabinet door 2 to be completely closed, maintaining overall aesthetics and sealing.

[0096] This design not only improves ease of use but also prevents potential damage to the door components during use. At the same time, it allows appliances to blend better into the home environment, enhancing the overall aesthetics.

[0097] In another embodiment, such as Figure 4 As shown, the door assembly and electrical body 1 are installed in the cabinet 13; during the opening or closing of the cabinet door 3, the transmission mechanism 5 is configured to drive the door panel 3 to move a preset distance on the cabinet door 2 so that the door panel 3 avoids the side wall of the cabinet 13.

[0098] Specifically, during the opening of the cabinet door 2, the transmission mechanism 5 drives the door panel 3 to move a preset distance away from the hinge 4 along the cabinet door 2 (a preset distance relative to the left side of the cabinet door 2). In this way, the door panel 3 can smoothly avoid the right side wall of the cabinet 13, allowing the cabinet door 2 to be fully opened, making it convenient for users to store and retrieve items.

[0099] Similarly, during the closing process of the cabinet door 2, the transmission mechanism 5 drives the door panel 3 to move a preset distance along the cabinet door 2 towards the hinge 4 (a preset distance relative to the rightward movement of the cabinet door 2). In this way, the door panel 3 can smoothly avoid the left side wall of the cabinet 13, allowing the cabinet door 2 to be completely closed, maintaining the overall aesthetics and airtightness.

[0100] In one embodiment of this application, such as Figures 3 to 6As shown, the transmission mechanism 5 includes a driving member 51, a driven member 52, and a transmission member 53. The driving member 51 is connected to the door 2, and the driven member 52 is connected to the door panel 3. The driving member 51 is connected to the driven member 52 via the transmission member 53, so that when the door 2 drives the driving member 51, the driven member 52 drives the door panel 3 to move along the door 2 towards or away from the hinge 4.

[0101] In this embodiment, the drive component 51 is connected to the door 2 via a drive mechanism, typically through rotation or sliding, so that the drive component 51 can rotate or move accordingly when the door 2 is opened or closed. This connection method can be the meshing of gears and racks, the connection of pulleys and ropes, etc., and the specific choice depends on design requirements and available technical conditions.

[0102] Accordingly, the driven member 52 is connected to the door panel 3 so that the door panel 3 can move as the driving member 51 rotates or moves. This connection method can be a pulley and rope connection, a shaft and a connecting rod connection, etc., and the specific choice depends on the design requirements and available technical conditions.

[0103] The driving component 51 is connected to the driven component 52 via a transmission component 53. The transmission component 53 transmits force, enabling the driven component 52 to rotate or move when the driving component 51 rotates or moves. This transmission connection can be an interconnection between components such as chains, gears, connecting rods, and racks; the specific choice depends on design requirements and available technical conditions.

[0104] When the refrigerator door 2 is opened or closed, the drive component 51 can drive the driven component 52 to move along the refrigerator door 2 in a direction closer to or further away from the hinge 4 (moving left or right relative to the refrigerator door 2). During this process, the door panel 3 will move along with the driven component 52, avoiding interference with the side wall of the cabinet and realizing smooth movement and reliable control of the refrigerator door.

[0105] In one specific embodiment, such as Figures 3 to 6 As shown, the transmission mechanism 5 also includes a transmission base 54. The transmission base 54 is disposed on the door 2, providing stable support and guidance. A first guide rail 541 is formed on one side of the transmission base 54, and a second guide rail 542 is formed on the other side. The first guide rail 541 and the second guide rail 542 on the transmission base 54 are arranged in parallel. A driving member 51 is slidably disposed on the first guide rail 541, and a driven member 52 is slidably disposed on the second guide rail 542, so as to provide stable guidance through the first guide rail 541 and the second guide rail 542.

[0106] The transmission component 53 includes a first connector 531 and a second connector 532. The first connector 531 passes around one end of the transmission base 54, and its two ends are respectively connected to one end of the driving component 51 and the driven component 52. The second connector 532 passes around the other end of the transmission base 54, and its two ends are respectively connected to the other end of the driving component 51 and the driven component 52.

[0107] During operation, the transmission mechanism 5 achieves stable and reliable transmission. As the cabinet door 2 opens or closes, the drive component 51 slides on the first guide rail 541, and simultaneously, through the connection of the first connecting component 531 and the second connecting component 532, drives the driven component 52 to slide on the second guide rail 542. This design precisely controls the movement trajectory and distance of the door panel 3, avoiding interference with the cabinet sidewalls and ensuring smooth opening and closing of the cabinet door 2.

[0108] Specifically, during the opening and closing process, the change in the angle of the cabinet door 2 causes the drive component 51 to move on the first guide rail 541. The connection between the first connector 531 and the second connector 532 causes the driven component 52 to move in the opposite direction on the second guide rail 542. Since the driven component 52 is connected to the door panel 3, the door panel 3 can move on the cabinet door 2, thereby allowing the door panel 3 to avoid the side cabinet.

[0109] It should be noted that a first mounting groove 21 is provided along one edge of the door 2, and the first mounting groove 21 has several screw holes. A first fixing block 543 and a second fixing block 544 are provided at both ends of the transmission base 54. The first fixing block 543 and the second fixing block 544 have through holes corresponding to the screw holes in the first mounting groove 21, thereby allowing the transmission base 54 to be fixed in the first mounting groove 21 by bolts installed on the first fixing block 543 and the second fixing block 544.

[0110] In one embodiment, such as Figures 3 to 6 As shown, two first guide rails 541 are formed on one side of the transmission base 54, arranged vertically opposite each other. The driving member 51 is slidably disposed between the two first guide rails 541. This further enhances the guiding effect on the driving member 51, enabling the driving member 51 to move more stably along the guide rail direction. The arrangement of the two first guide rails 541 improves the overall stability and reliability of the transmission mechanism 5, which is beneficial for achieving precise control and smooth movement.

[0111] Similarly, two opposing second guide rails 542 can be formed on the other side of the transmission base 54, with the driven member 52 slidably disposed between the two second guide rails 542. This enhances the guiding effect on the driven member 52, allowing it to move more stably along the guide rail direction. The arrangement of the two second guide rails 542 improves the stability and reliability of the driven member 52, further optimizing the movement trajectory and distance control of the door panel 3. This design, by increasing the number of guide rails, improves the overall rigidity and stability of the transmission mechanism 5, enabling the door assembly to open and close more smoothly and stably.

[0112] In some embodiments, such as Figures 3 to 6 As shown, the driving component 51 includes a connecting rod 512 and a first slider 511. One end of the connecting rod 512 is rotatably connected to the hinge 4 or hinged to the electrical body 1, and the other end of the connecting rod 512 is rotatably connected to the first slider 511. The first slider 511 is slidably disposed on the first guide rail 541.

[0113] In this embodiment, one end of the connecting rod 512 is hinged to the fixed seat 514 via the first pin 513, and the other end of the connecting rod 512 is hinged to the mounting plate 518 on the first slider 511 via the second pin 515. The fixed seat 514 is fixed in the screw hole on the hinge 4 by screws. When the door 2 rotates, the connecting rod 512 rotates accordingly to drive the first slider 511 to move on the first guide rail 541. The connection between the first connecting member 531 and the second connecting member 532 drives the driven member 52 to move in the opposite direction on the second guide rail 542. Since the driven member 52 is connected to the door panel 3, the door panel 3 can move on the door 2. The sliding connection between the first slider 511 and the first guide rail 541 realizes the stable movement of the driving member 51.

[0114] Accordingly, the driven member 52 includes a second slider 521. The second slider 521 is slidably disposed on the second guide rail 542 and is connected to the door panel 3. Driven by the first connecting member 531 and the second connecting member 532, the second slider 521 can move on the second guide rail 542, thereby driving the door panel 3 to move. Through the sliding connection between the second slider 521 and the second guide rail 542, stable movement of the driven member 52 is achieved.

[0115] Furthermore, considering the needs of practical applications, limiting structures can also be provided at the ends of both sides of the first guide rail 541 and the second guide rail 542. Through the restriction of the limiting structures, the first slider 511 and the second slider 521 can move within a set range of motion, allowing the movement distance to be set according to requirements to meet the usage requirements of different occasions.

[0116] In practical applications, the limiting structure allows the first slider 511 and the second slider 521 to move within a set range. This design fully satisfies the movement distances set according to different needs. The first slider 511 and the second slider 521 can reach the predetermined position during movement and stop when they reach the limit position, avoiding damage or safety hazards caused by excessive movement. In addition, this limiting structure also allows for convenient control of the first slider 511 and the second slider 521. By setting different limiting points, precise control of the slider movement can be achieved, thereby accurately controlling the movement distance of the door panel 3 and meeting the needs of various application scenarios.

[0117] In one embodiment, such as Figure 5 and Figure 6 As shown, a positioning member 516 and a limiting member 517 corresponding to the positioning member 516 are formed on the driving member 51 and / or the driven member 52. The first connecting member 531 and / or the second connecting member 532 pass through the limiting member 517 and are connected to the positioning member 516.

[0118] In one specific embodiment, the positioning member 516 may be a column, which is vertically disposed on the first slider 511 and the second slider 521, while the limiting member 517 may be an arched rib. The first slider 51 of the driving member 51 has two columns and corresponding arched ribs on both sides. The second slider 521 of the driven member 52 has two columns and corresponding arched ribs on both sides. One end of the first connecting member 531 passes through one of the arched ribs of the first slider 511 and wraps around the corresponding column, while the other end of the first connecting member 531 passes through one of the arched ribs of the second slider 521 and wraps around the corresponding column. One end of the second connector 532 passes through the first slider 511 and is wrapped around the corresponding column by another arched rib. The other end of the second connector 532 passes through the second slider 521 and is wrapped around the corresponding column by another arched rib. Through the cooperation of the first connector 531, the second connector 532, the column and the arched rib, not only is the connection between the first slider 511 and the second slider 521 realized, but also the limitation of the arched rib makes it easier to transmit power between the first slider 511 and the second slider 521.

[0119] In one example, such as Figure 3 and Figure 7 As shown, the door panel assembly also includes a connecting mechanism 8, which is connected to the door panel 3. The connecting mechanism 8 can be a separate component or part of the door panel 3. One of the second slider 521 and the connecting mechanism 8 forms a first slot 522, and the other forms a first connector 81 adapted to the first slot 522. The second slider 521 is detachably connected to the connecting mechanism 8 through the first connector 81 and the first slot 522.

[0120] In this embodiment, the second slider 521 is provided with a first slot 522, and a notch is provided on one side of the first slot 522. The connecting mechanism 8 is provided with a first connector 81, which can pass through the notch and be fixed in the first slot 522. Since the connecting mechanism 8 is connected to the door panel 3, the connection between the second slider 521 and the door panel 3 can be realized through the connection between the first connector 81 and the first slot 522.

[0121] This detachable connection method makes the connection between the second slider 521 and the connecting mechanism 8 more flexible and convenient. Whether to install the connecting mechanism 8 can be selected based on actual needs, and a suitable connection method can be chosen according to different usage scenarios. This design improves the versatility and adaptability of the door panel assembly, while simplifying the manufacturing and assembly process and reducing production and maintenance costs.

[0122] In another embodiment, such as Figure 3 and Figure 7 As shown, a first slot 522 is formed on the second slider 521. The connecting mechanism 8 includes a fixing plate 83 and a connecting block 82. The fixing plate 83 is connected to the door panel 3, providing additional structural support for the door panel 3. A mounting groove is formed on the fixing plate 83 to accommodate the connecting block 82. The connecting block 82 is slidably disposed in the mounting groove, and a first locking connector 81 is formed on the connecting block 82 to adjust the relative position of the door panel 3 and the cabinet door 2 by adjusting the position of the connecting block 82 in the mounting groove. Through this adjustable design, the user can adjust the position of the door panel 3 according to actual needs to meet the needs of different usage scenarios.

[0123] Specifically, the first snap-fit ​​connector 81 is a U-shaped hook facing downwards, which can slide through the notch into the first snap-fit ​​groove 522. The connecting block 82 has a first rectangular hole extending vertically, and the fixing plate 83 has two mounting holes and a mounting groove extending horizontally between the two mounting holes. The side wall of the mounting groove has a second rectangular hole extending horizontally. The connecting block 82 can slide in the mounting groove. By controlling the position of the connecting block 82 in the mounting groove, the connecting block 82 can be moved vertically relative to the fixing plate 83. Screws can be installed to pass through the first rectangular hole in the mounting groove and the second rectangular hole in the connecting block 82, forming a connecting block 82 that can be adjusted in both vertical and horizontal directions. The relative position of the mounting hole of the fixing plate 83 and the door panel 3 can be adjusted in both vertical and horizontal directions.

[0124] like Figure 7 and Figure 8 As shown, the installation process of the connecting mechanism 8, which is adapted to the transmission mechanism 5, and the door panel 3 is as follows:

[0125] The connecting block 82 is inserted into the mounting groove of the fixing plate 83. Screws are passed through the second rectangular hole, the first rectangular hole, and the door panel 3 to connect the connecting mechanism 8 to the door panel 3. The first snap-fit ​​connector 81 on the connected connecting block 82 is then hooked into the first snap-fit ​​groove 522 to complete the connection between the connecting block 82 and the second slider 521. The positional relationship between the door panel 3 and the cabinet door 2 is then observed to check for any deviation. If a deviation exists, the position can be adjusted through the first and second rectangular holes. If the deviation is large, the screws can be removed to separate the connecting mechanism 8 from the door panel 3, and the position of the connecting mechanism 8 can be adjusted. The door panel 3, fixing plate, and connecting block assembly are used to adjust the position of the connecting block 82. If the positional relationship meets the requirements and no adjustment is needed, screws are passed through the mounting holes on both sides of the fixing plate 83 and the door panel 3 to further fix the door panel 3 to the fixing plate 83 to maintain its stable position. This method not only allows for fine-tuning of the position of the connecting mechanism 8 but also ensures that all fixations are secure, guaranteeing the accurate positional relationship between the door panel 3 and the cabinet door 2.

[0126] In one embodiment, such as Figure 3 and Figure 9 As shown, the door assembly also includes a guide mechanism 6; the guide mechanism 6 includes a guide base 62 and a third slider 61. The guide base 62 is disposed on the door 2, and a third guide rail 621 is formed on the guide base 62. The third slider 61 is slidably disposed on the third guide rail 621 and is connected to the door panel 3.

[0127] The third slider 61 is connected to the door panel 3. This connection method can be selected according to actual needs, such as by screws, welding, or clips. With this connection method, when the door panel 3 slides relative to the cabinet door 2, the door panel 3 can push the third slider 61 to slide on the third guide rail 621, which can greatly increase the stability of the door panel 3 and the cabinet door 2 during relative sliding.

[0128] Furthermore, by designing the third guide rail 621, such as by setting a limiting structure at the end of the third guide rail 621, the moving distance of the door panel 3 can be adjusted according to actual needs to meet the needs of different users.

[0129] The door 2 is provided with a first mounting groove 21 adapted to the transmission mechanism 5, and the transmission mechanism 5 is installed in the first mounting groove 21; and / or, the door 2 is provided with a second mounting groove 22 adapted to the guide mechanism 6, and the guide mechanism 6 is installed in the second mounting groove 22.

[0130] Inside the door 2, there is a first mounting groove 21 adapted to the transmission mechanism 5, allowing the transmission mechanism 5 to be smoothly installed in the first mounting groove 21. This design enables the door 2 to form a stable cooperation with the transmission mechanism 5 during opening and closing, reducing the overall thickness of the door 2 and the door panel 3.

[0131] In addition, the door 2 is also provided with a second mounting groove 22 adapted to the guide mechanism 6. The function of the guide mechanism 6 is to provide stable guidance during the movement of the door 2, preventing the door 2 from shaking or deviating from the track when opening and closing. By installing the guide mechanism 6 in the second mounting groove 22, the stability and accuracy of the door 2 during movement can be ensured, and the overall thickness of the door 2 and the door panel 3 can be reduced.

[0132] Typically, two vertically opposed third guide rails 621 are formed on one side of the guide base 62, and a third slider 61 is slidably disposed between the two third guide rails 621. This enhances the guiding effect on the third slider 61, allowing it to move more stably along the guide rail direction. The arrangement of the two third guide rails 621 improves the overall stability and reliability during guidance, facilitating precise control and smooth movement.

[0133] To facilitate the fixing of the guide mechanism 6, the connecting mechanism 8 is provided with multiple components. The third slider 61 and one of the connecting mechanisms 8 form a second slot 611, and the other forms a second connector that is adapted to the second slot 611. The third slider 61 is detachably connected to the connecting mechanism 8 through the second connector and the second slot 611.

[0134] In this embodiment, the third slider 61 is provided with a second slot 611, and a notch is provided on one side of the second slot 611. The connecting mechanism 8 is provided with a second connector, which can pass through the notch and be fixed in the second slot 611. Since the connecting mechanism 8 is connected to the door panel 3, the connection between the third slider 61 and the door panel 3 can be realized through the connection between the second connector and the second slot 611.

[0135] This detachable connection method makes the connection between the third slider 61 and the connecting mechanism 8 more flexible and convenient. Whether to install the connecting mechanism 8 can be chosen according to actual needs, and a suitable connection method can be selected based on different usage scenarios. This design improves the versatility and adaptability of the door panel assembly, while simplifying the manufacturing and assembly process and reducing production and maintenance costs.

[0136] In this embodiment, the first snap-fit ​​connector 81 and the second snap-fit ​​connector have the same structure, that is, the connecting mechanism 8 used to connect the second slider 521 has the same structure as the connecting mechanism used to connect the third slider 61. Figure 7As shown, the connecting mechanism 8 includes a fixing plate 83 and a connecting block 82. The fixing plate 83 is connected to the door panel 3, providing additional structural support for the door panel 3. A mounting groove is formed on the fixing plate 83 to accommodate the connecting block 82. The connecting block 82 is slidably disposed in the mounting groove, and a first locking connector 81 is formed on the connecting block 82 to adjust the relative position of the door panel 3 and the cabinet door 2 by adjusting the position of the connecting block 82 in the mounting groove. Through this adjustable design, users can adjust the position of the door panel 3 according to actual needs to meet the requirements of different usage scenarios.

[0137] Specifically, the second connector is a U-shaped hook facing downwards, which can slide through the notch into the second slot 611. The connecting block 82 has a first rectangular hole extending vertically, and the fixing plate 83 has two mounting holes and a mounting groove extending horizontally between the two mounting holes. The side wall of the mounting groove has a second rectangular hole extending horizontally. The connecting block 82 can slide in the mounting groove. By controlling the position of the connecting block 82 in the mounting groove, the connecting block 82 can be moved vertically relative to the fixing plate 83. Screws can be installed to pass through the first rectangular hole in the mounting groove and the second rectangular hole in the connecting block 82, forming a connecting block 82 that can be adjusted in both vertical and horizontal directions. The relative position of the mounting hole of the fixing plate 83 and the door panel 3 can be adjusted in both vertical and horizontal directions.

[0138] like Figures 7 to 9 As shown, the installation process of the connecting mechanism 8, which is adapted to the guide mechanism 6, and the door panel 3 is as follows:

[0139] The connecting block 82 is inserted into the mounting groove of the fixing plate 83. Screws are passed through the second rectangular hole, the first rectangular hole, and the door panel 3 to connect the connecting mechanism 8 to the door panel 3. The second snap-fit ​​connector on the connected connecting block 82 is then attached to the second snap-fit ​​groove 611 to complete the connection between the connecting block 82 and the third slider 61. The positional relationship between the door panel 3 and the cabinet door 2 is then observed to check for any deviation. If a deviation exists, the position can be adjusted through the first and second rectangular holes. If the deviation is large, the screws can be removed to separate the connecting mechanism 8 from the door panel 3, and the position of the connecting mechanism 8 can be adjusted. The door panel 3, fixing plate, and connecting block assembly are used to adjust the position of the connecting block 82. If the positional relationship meets the requirements and no adjustment is needed, screws are passed through the mounting holes on both sides of the fixing plate 83 and the door panel 3 to further fix the door panel 3 to the fixing plate 83 to maintain its positional stability.

[0140] In some embodiments, such as Figure 3As shown, multiple guide mechanisms 6 are provided. To coordinate with the guidance, the third guide rail 621 in each guide mechanism 6 is arranged parallel to the first guide rail 541 and the second guide rail 542 on the transmission mechanism 5. This parallel arrangement design ensures that the door panel 3 can be accurately guided during movement, avoiding interference with the cabinet side wall. Through the cooperation of this guide mechanism 6 and the transmission mechanism 5, the smooth and stable movement of the door panel 3 can be achieved, improving ease of use and reliability.

[0141] This design can be adjusted and optimized according to actual needs, such as changing the number, position, and size of the guide mechanisms 6, and adjusting the parallelism between the third guide rail 621 and the first guide rail 541 and the second guide rail 542. These adjustments can be made according to specific usage scenarios to achieve optimal performance and user experience.

[0142] Specifically, such as Figure 3 , Figures 9 to 11 As shown, in this embodiment, the door 2 has one first mounting slot 21 and three second mounting slots 22. The first mounting slot 21 is located on the top right side of the door 2, one second mounting slot 22 is located on the top left side of the door 2, and the other two second mounting slots 22 are located on the left and right sides of the bottom of the door 2, respectively. The corresponding door assembly has one transmission mechanism 5 and three guide mechanisms 6. The transmission mechanism 5 is installed in the first mounting slot 21, and the other three guide mechanisms 6 are respectively located in the three second mounting slots 22. One of the three guide mechanisms 6 is the top guide mechanism, such as... Figure 9 As shown. The other two guide mechanisms 6 are bottom guide mechanisms, as shown. Figure 10 As shown. The top guide mechanism 6 and the bottom guide mechanism 6 have the same structure and are arranged symmetrically.

[0143] like Figure 8 and Figure 12 As shown, there are four connecting mechanisms 8, corresponding to one transmission mechanism 5 and three guide mechanisms 6 respectively. The connection process is as follows: first, the connecting mechanism 8 is fixed to the door panel 3 through the first rectangular hole and the second rectangular hole; then, the connecting mechanism 8 is connected to the corresponding slider; finally, after adjusting the door 2 and the door panel 3 to ensure there are no problems, screws are used to pass through the mounting holes on both sides of the fixing plate 83 and the door panel 3 to further fix the door panel 3 to the fixing plate 83. The specific process can be referred to the above embodiment, and will not be repeated here.

[0144] like Figure 1 and Figure 2As shown, when the cabinet door 2 is open, the transmission mechanism 5 drives the door panel 3 to move a preset distance away from the hinge 4 along the cabinet door 2. During this process, the door panel 3 moves outward under the constraint of the three guide mechanisms 6. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet 12 and ensure stability during movement, allowing the cabinet door 2 to be fully opened for convenient storage and retrieval of items. Similarly, when the cabinet door 2 is closed, the transmission mechanism 5 drives the door panel 3 to move a preset distance closer to the hinge 4 along the cabinet door 2. During this process, the door panel 3 moves inward under the constraint of the three guide mechanisms 6. In this way, the door panel 3 can smoothly avoid the side wall of the first cabinet 11, allowing the cabinet door 2 to be fully closed, maintaining overall aesthetics and sealing.

[0145] In some embodiments, such as Figure 13 and Figure 14 As shown, the transmission mechanism 5 further includes a first rotating shaft 57 and a second rotating shaft 58. The transmission component 53 includes a transmission belt, which is sleeved on the first rotating shaft 57 and the second rotating shaft 58. The transmission belt includes an upper belt 533 located on one side of the first rotating shaft 57 and the second rotating shaft 58 and a lower belt 534 located on the other side of the first rotating shaft and the second rotating shaft. The driving component 51 is disposed on the upper belt 533, and the driven component 52 is disposed on the lower belt 534.

[0146] In this embodiment, the first rotating shaft 57 and the second rotating shaft 58 are used for support and transmission, ensuring the stable movement of the driving member 51, the driven member 52, and the transmission member 53. The transmission member 53 adopts the form of a transmission belt, which has high flexibility and can adapt to different motion trajectories and distance requirements. The transmission belt is sleeved on the first rotating shaft 57 and the second rotating shaft 58, and the tension and movement of the transmission belt are achieved by the rotation of these two rotating shafts.

[0147] The drive component 51 is mounted on the upper side belt 533. During the rotation of the door 2, the drive component 51 drives the upper side belt 533 to move along the first direction, and the lower side belt 534 moves along the second direction under the traction of the upper side belt 533. Since the driven component 52 is mounted on the lower side belt 534 and is connected to the door panel 3, the relative sliding between the door panel 3 and the door 2 can be controlled under the traction of the lower side belt 534.

[0148] Specifically, such as Figure 1 and Figure 2 As shown, during the opening of the cabinet door 2, the drive component 51 drives the upper side belt 533 to move inward, while the lower side belt 534 drives the door panel 3 to move a preset distance away from the hinge 4 along the cabinet door 2 via the driven component 52. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet 12, allowing the cabinet door 2 to be fully opened, making it convenient for users to store and retrieve items.

[0149] Similarly, during the closing process of the cabinet door 2, the drive component 51 drives the upper side belt 533 to move outward, while the lower side belt 534 drives the door panel 3 to move a preset distance along the cabinet door 2 towards the hinge 4 via the driven component 52. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet 12, allowing the cabinet door 2 to be completely closed.

[0150] Furthermore, by adjusting the position and angle of the first rotating shaft 57 and the second rotating shaft 58, the movement trajectory and distance of the transmission belt can be adjusted according to actual needs to meet the requirements of different users.

[0151] To adjust the travel of the drive member 51 and the driven member 52 to accommodate different user needs, the door assembly also includes a travel adjuster. The travel adjuster is configured to make the travel of the drive member 51 with the upper sideband 533 different from the travel of the driven member 52 with the lower sideband 534.

[0152] The stroke adjustment component can be set as a pulley block or movable pulley, etc., to change the stroke of the driving component 51 and the driven component 52. For example, the stroke of the driving component 51 can be reduced to increase the stroke of the driven component 52, so as to solve the interference problem caused by insufficient movement displacement of the small-angle door panel 3.

[0153] In this embodiment, to increase the displacement of the door panel 3, the stroke adjuster reduces its stroke relative to the upper side band 533, making the displacement of the driven member 52 on the lower side band 534 twice that of the driving member 51, thereby increasing the displacement of the door panel 3 on the door 2. Furthermore, the design of the stroke adjuster allows for adjustment of the door panel 3's movement trajectory according to actual needs, satisfying the requirements of different users.

[0154] In one embodiment, such as Figures 15 to 18 As shown, the driving component 51 includes a first rack, the driven component 52 includes a second rack, and the transmission component 53 includes a transmission gear; the first rack is connected to the door 2, the second rack is connected to the door panel 3, and the transmission gear is disposed between the first rack and the second rack. The transmission gear meshes with the first rack and the second rack so that when the door 2 drives the first rack to move, the second rack drives the door panel 3 to move in the opposite direction.

[0155] Specifically, in this embodiment, both the first rack and the second rack are mounted on the support frame 56. The support frame 56 has a first slide rail for the first rack to move and a second slide rail for the second rack to move. A transmission gear is disposed between the first rack and the second rack. The first rack is connected to the door 2 via a connecting rod. During the rotation of the door 2, the first rack can be pushed to move along the first slide rail in a first direction. After the transmission gear reverses direction, the second gear moves along the second slide rail in a second direction, so that the first rack and the second rack can move in different directions, thereby controlling the relative sliding between the door panel 3 and the door 2.

[0156] Specifically, such as Figure 1 and Figure 2 As shown, during the opening of the cabinet door 2, the cabinet door 2 drives the first rack to move inward. Under the reverse direction of the transmission gear, the second rack drives the door panel 3 to move a preset distance away from the hinge 4 along the cabinet door 2. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet 12, allowing the cabinet door 2 to be fully opened, making it convenient for users to store and retrieve items.

[0157] Similarly, during the closing process of the cabinet door 2, the cabinet door 2 drives the first rack to move outward. Under the reverse direction of the transmission gear, the second rack drives the door panel 3 to move a preset distance along the cabinet door 2 towards the hinge 4. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet 12, allowing the cabinet door 2 to be completely closed.

[0158] It should be noted that, as Figure 16 and Figure 17 As shown, in this embodiment, the door assembly further includes a guide mechanism 6. The guide mechanism 6 includes a guide base 62 and a third slider 61. The guide base 62 is disposed on the door 2, and a third slide rail 622 is formed on the guide base 62. The third slider 61 is slidably disposed on the third slide rail 622 and is connected to the door panel 3. The connection method between the third slider 61 and the door panel 3 can be selected according to actual needs, such as by screws, welding, or snap-fit. With this connection method, when the door panel 3 slides relative to the door 2, the door panel 3 can push the third slider 61 to slide on the third slide rail 622, which can significantly increase the stability of the door panel 3 during the relative sliding process between the door panel 3 and the door 2.

[0159] In another embodiment of this application, a refrigeration device is provided. The refrigeration device includes a housing and a door assembly. The door assembly includes a door 2, a door panel 3, and a transmission mechanism 5. The housing forms a storage space; the door 2 is rotatably connected to the housing via a hinge 4, and the door 2 is adapted to open or close the storage space of the housing; the door panel 3 is slidably disposed on the outside of the door 2, and the transmission mechanism 5 drives the door panel 3 to move relative to the door 2 during the opening or closing of the door 2.

[0160] During the opening of the door 2, the transmission mechanism 5 drives the door panel 3 to move away from the hinge 4 (moving to the left relative to the door 2), thus preventing the door panel 3 from interfering with objects on the side. During the closing of the door 2, the transmission mechanism 5 drives the door panel 3 to move closer to the hinge 4 (moving to the right relative to the door 2), thus ensuring that the door panel 3 avoids objects on the side when closed.

[0161] The combination of door 2 and door panel 3 prevents interference between door panel 3 and surrounding objects when the refrigeration unit is opened and closed, greatly improving ease of use. This design advantage is particularly evident in confined kitchen environments. Furthermore, the transmission mechanism 5 allows door panel 3 to move smoothly during opening and closing, improving the refrigerator's lifespan and stability.

[0162] The refrigeration device in this application is used, for example, as a refrigerator; however, it should be understood that the refrigeration device in this application can also be used as a freezer or any other suitable device, without limitation.

[0163] It is understood that if the door assembly has the beneficial effects of the above embodiments, then the refrigeration equipment will have the corresponding beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and will not be repeated in this application.

[0164] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should be covered within the scope of the claims of this application.
