[0030] Combine the following Figures 1 to 6 The door assembly and refrigeration device of the present application are described. The door assembly of the present application can be applied to household appliances, such as refrigerators, but it should be understood that the door assembly of the present application can also be applied to dishwashers, washing machines or any other suitable devices. The refrigeration device of the present application is applied to refrigerators, for example, but it should be understood that the refrigeration device of the present application can also be applied to freezers or any other suitable devices.

[0031] In one embodiment of the present application, Figures 1 to 4As shown, the door assembly is applied to a refrigeration device, and the refrigeration device includes: a box body 4, and the door assembly includes: a box door 2, a door panel 3, a traction mechanism 9 and a first sliding door mechanism 1. The box door 2 is rotatably connected to the box body 4 of the refrigeration device, and is suitable for opening or closing the storage space of the box body 4. The outer side of the box door 2 is provided with a first mounting groove 21; the door panel 3 is slidably arranged on the outer side of the box door 2; the first sliding door mechanism 1 is arranged in the first mounting groove 21, one end of the first sliding door mechanism 1 is transmission-connected to the box body 4 through the traction mechanism 9, and the other end of the first sliding door mechanism 1 is connected to the door panel 3. In the process of opening or closing the box door 2, the traction mechanism 9 drives the first sliding door mechanism 1, so that the first sliding door mechanism 1 drives the door panel 3 to move relative to the width direction of the box door 2.

[0032] In this embodiment, in order to assemble the first sliding door mechanism 1, a first installation groove 21 is designed on the outer side of the box door 2, and the first installation groove 21 provides an installation position and space for the first sliding door mechanism 1. In order to enable the door panel 3 to avoid obstacles such as walls and objects on the side, the door panel 3 is slidably arranged on the outer side of the box door 2. The traction mechanism 9 is mainly used to connect the box body 4 and the first sliding door mechanism 1, and is used to transmit power, and is responsible for converting the movement of the box body 4 (such as opening or closing) into the driving force of the first sliding door mechanism 1.

[0033] When the user turns the door 2, the traction mechanism 9 drives the first sliding door mechanism 1 to perform corresponding actions under the drive of the relative movement between the door 2 and the box body 4. The first sliding door mechanism 1 is arranged in the first mounting groove 21 on the outer side of the door 2. One end of the first sliding door mechanism 1 is connected to the box body 4 through the traction mechanism 9, and the other end is connected to the door panel 3. In this way, when the door 2 is opened or closed, the first sliding door mechanism 1 can receive the driving force from the traction mechanism 9 and drive the door panel 3 to move relative to the width direction of the door 2 to avoid obstacles such as walls and objects on the side.

[0034] According to the door assembly of the embodiment of the present invention, the first sliding door mechanism 1 can be hidden in the entire door assembly by arranging the first sliding door mechanism 1 in the first mounting groove 21 on the outer side of the box door 2. One end of the first sliding door mechanism 1 is connected to the box body 4 through the traction mechanism 9, and the other end of the first sliding door mechanism 1 is connected to the door panel 3, so that the first sliding door mechanism 1 drives the door panel 3 to move relative to the width direction of the box door 2 during the process of opening or closing the box door 2, so that the door panel 3 avoids obstacles such as walls and objects on the side.

[0035] In some embodiments, Figures 1 to 4As shown, the first sliding door mechanism 1 is vertically arranged in the first mounting groove 21, and the first sliding door mechanism 1 includes: a first base 13, a first slider 11, a second slider 12 and a first connecting member. A first guide rail 131 is formed on the upper side of the first base 13, and a second guide rail 132 is formed on the lower side; the first slider 11 is slidably arranged on the first guide rail 131, and the first slider 11 is used for transmission connection with the box body 4 through the traction mechanism 9; the second slider 12 is slidably arranged on the second guide rail 132 and connected to the door panel 3; the two ends of the first connecting member are respectively connected to the first slider 11 and the second slider 12; when the first slider 11 moves on the first guide rail 131, the first slider 11 drives the second slider 12 to move in the opposite direction on the second guide rail 132 through the first connecting member, so as to drive the door panel 3 to move relative to the width direction of the box door 2.

[0036] Specifically, if Figure 2 and Figure 3 As shown, the first guide rail 131 is located on the upper side of the first base 13, providing a sliding track for the first slider 11. The second guide rail 132 is located on the lower side of the first base 13, parallel to or at a certain angle to the first guide rail 131, providing a sliding track for the second slider 12. The first slider 11 is slidably arranged on the first guide rail 131, and the first slider 11 is transmission-connected to the box body 4. The second slider 12 is slidably arranged on the second guide rail 132, and is connected to the door panel 3. The two ends of the first connecting member are respectively connected to the first slider 11 and the second slider 12.

[0037] When the door 2 is opened or closed, the relative movement between the box body 4 and the door 2 causes the first slider 11 to move on the first guide rail 131 under the driving force. Since the two ends of the first connecting member are respectively fixed to the first slider 11 and the second slider 12, by reasonably setting the extension direction of the first connecting member, the first connecting member will drive the second slider 12 to move in the opposite direction on the second guide rail 132. This synchronous reverse movement feature enables the door panel 3 to slide relative to the width direction of the box body 4.

[0038] The first sliding door mechanism 1 provided by the present invention, by respectively arranging the first slider 11 and the second slider 12 on the first guide rail 131 and the second guide rail 132, and connecting the first slider 11 and the second slider 12 using a first connecting member, so that when the first slider 11 moves, it can drive the second slider 12 to move in the opposite direction. Therefore, when the first slider 11 is transmission-connected to the box body 4 and the second slider 12 is connected to the door panel 3, the first sliding door mechanism 1 can be used to drive the door panel 3 to slide in the width direction of the box door 2, thereby enabling the door panel 3 to avoid obstacles such as side walls and objects during the closing or opening process of the box door 2, so as to meet the user's usage requirements in different scenarios.

[0039] It should be noted that, in practical applications, the designs of the first slider 11 and the second slider 12 can be flexible and varied to adapt to different working scenarios and performance requirements. They are not limited to specific shapes, sizes or materials, but can be customized and optimized according to specific needs.

[0040] From the material point of view, the first slider 11 and the second slider 12 can be made of materials with high wear resistance, low friction coefficient and good stability, such as metal alloys, engineering plastics or special lubricating materials. The selection of these materials is intended to improve the durability of the sliders, reduce wear and noise during sliding, and ensure smooth sliding.

[0041] In terms of structural design, the first slider 11 and the second slider 12 can adopt various forms of guide rail contact surfaces, such as plane contact, ball contact or sliding bearing contact. These different contact methods have their own advantages and disadvantages. For example, ball contact can reduce friction and wear, but the cost is high; while plane contact has a simple structure, but may require more frequent lubrication and maintenance. Therefore, factors such as usage conditions, cost-effectiveness and maintenance convenience should be comprehensively considered when selecting.

[0042] In addition, in order to enhance the bearing capacity and stability of the slider, reinforcing ribs, support plates or other auxiliary structures may be added to the first slider 11 and the second slider 12. These structures can increase the rigidity and anti-deformation ability of the slider, ensuring stable sliding performance when bearing the weight of the door panel 3 and external forces.

[0043] In some embodiments, Figure 5 As shown, the first connecting member includes a first flexible cable and a second flexible cable, and the first flexible cable and the second flexible cable can be ropes. The first flexible cable passes over one end of the first base 13, and the two ends are respectively connected to one end of the first slider 11 and the second slider 12; the second flexible cable passes over the other end of the first base 13, and the two ends are respectively connected to the other ends of the first slider 11 and the second slider 12.

[0044] Specifically, one end of the first flexible cable is fixed at a predetermined position of the first slider 11, then passes around a specific portion of the first base 13 (such as a pulley or guide device on the base), and finally connects to a corresponding position of the second slider 12. In this way, when the first slider 11 moves on the first guide rail 131, the first flexible cable can smoothly transmit this movement and drive the second slider 12 to move in the opposite direction on the second guide rail 132.

[0045] Similarly, the second flexible cable also bypasses the other end of the first base 13, but the path is different from that of the first flexible cable to ensure the balance and stability between the two sliders. One end of the second flexible cable is fixed at another predetermined position of the first slider 11 (opposite to the connection point of the first flexible cable), bypasses the other side of the first base 13, and finally connects to the other end of the second slider 12. This double flexible cable design not only enhances the reliability of the connection, but also makes the entire first sliding door mechanism 1 more stable and smooth during operation.

[0046] The performance of the sliding door mechanism can be further optimized by adjusting the bypass paths and fixed point positions of the first and second flexible cables on the first base 13. For example, the tension of the first and second flexible cables can be adjusted to ensure the synchronization and consistency of the first and second sliders 11 and 12 during movement.

[0047] In this embodiment, Figures 1 to 4 As shown, the first mounting groove 21 is located on the outside of the box door 2, and the first sliding door mechanism 1 is vertically arranged in the first mounting groove 21. Compared with the horizontal arrangement of the first sliding door mechanism 1, the depth of the first mounting groove 21 can be reduced to a certain extent, and the thickness of the box door 2 can be reduced. The first guide rail 131 and the second guide rail 132 are arranged in parallel and side by side. This arrangement not only enhances the stability and bearing capacity of the first sliding door mechanism 1, but also makes the movement of the first slider 11 and the second slider 12 more stable and smooth. The first guide rail 131 faces the upper side. Such a design makes it easier for the first slider 11 on the first guide rail 131 to be connected to the traction mechanism 9. The traction mechanism 9 is usually located near the top of the box body 4. The second guide rail 132 faces the lower side to be opposite to the first guide rail 131, and cooperates to connect the door panel 3.

[0048] In some embodiments, a first ball and a first support member are provided between the first slider 11 and the first guide rail 131 and between the second slider 12 and the second guide rail 132. The first support member is provided with a first rolling notch, and the first ball is rollably disposed in the first rolling notch.

[0049] In this embodiment, a first support frame is set between the first slider 11 and the first guide rail 131, and a first support frame is set between the second slider 12 and the second guide rail 132 to limit the first ball therein to prevent the first ball from shifting when rolling, so that the sliding of the first slider 11 and the second slider 12 is more stable and reliable.

[0050] Specifically, the first rolling notch is an arc-shaped notch that matches the shape of the first ball. The arc-shaped notch is provided to enhance the limiting effect on the first ball, and when the first rolling notch contacts the first ball, the force receiving area is larger and the force is more dispersed, which can reduce the wear between the first support frame and the first ball and extend the service life.

[0051] In some embodiments, Figures 1 to 4 As shown, a second mounting groove 22 is provided on the outer side of the box door 2; the door body assembly also includes: a second sliding door mechanism 10 and a connecting rod 8; the second sliding door mechanism 10 is arranged in the second mounting groove 22, one end of the second sliding door mechanism 10 is connected to the first sliding block 11 through the connecting rod 8, and the other end of the second sliding door mechanism 10 is connected to the door panel 3, and the second sliding door mechanism 10 is configured to cooperate with the first sliding door mechanism 1 to drive the door panel 3 to move relative to the width direction of the box door 2 during the process of opening or closing the box door 2.

[0052] Specifically, a second mounting groove 22 is provided on the outer side of the box door 2, and the second mounting groove 22 provides an installation space for the second sliding door mechanism 10. The main function of the second sliding door mechanism 10 is to cooperate with the first sliding door mechanism 1. In the process of opening or closing the box door 2, the second sliding door mechanism 10 is also used to drive the door panel 3 to move relative to the width direction of the box door 2. The connecting rod 8, as a component connecting the second sliding door mechanism 10 and the first slider 11, plays a role in transmitting force and motion. When the second sliding door mechanism 10 is driven by the first slider 11 on the first sliding door mechanism 1, the second sliding door mechanism 10 can cooperate with the driving door panel 3 to move. This design enables the door panel 3 to be further driven by the second sliding door mechanism 10 on the basis of being driven by the first sliding door mechanism 1, thereby increasing the driving force when the door panel 3 moves, and increasing the stability of the door panel 3 when it moves relative to the box door 2.

[0053] In some embodiments, Figures 1 to 4 As shown, the second sliding door mechanism 10 is vertically arranged in the second mounting groove 22, and includes: a second base 101, a third slider 102, a fourth slider 103 and a second connecting member. A third guide rail 1011 is formed on the upper side of the second base 101, and a fourth guide rail 1012 is formed on the lower side; the third slider 102 is slidably arranged on the third guide rail 1011, and the third slider 102 is connected to the first slider 11 through the connecting rod 8; the fourth slider 103 is slidably arranged on the fourth guide rail 1012, and is used to connect with the door panel 3; the two ends of the second connecting member are respectively connected to the third slider 102 and the fourth slider 103; in the process of opening or closing the box door 2, the third slider 102 and the fourth slider 103 move in opposite directions to drive the door panel 3 to move relative to the width direction of the box door 2.

[0054] In this embodiment, the second base 101 serves as the main body of the second sliding door mechanism 10, and the second base 101 provides a stable installation foundation and a sliding track. The third guide rail 1011 formed by the second base 101 is the sliding path of the third slider 102, and the fourth guide rail 1012 formed is the sliding path of the fourth slider 103. The third slider 102 is slidably arranged on the third guide rail 1011, and cooperates with the transmission of the first slider 11 through the connecting rod 8. The fourth slider 103 is slidably arranged on the fourth guide rail 1012 and connected to the door panel 3.

[0055] During the sliding process, the third slider 102 is driven by the connecting rod 8 to move linearly along the third guide rail 1011, thereby driving the fourth slider 103 to move, so that the door panel 3 moves accordingly. The connecting rod 8 connects the first slider 11 and the third slider 102, so that the second sliding door mechanism 10 can receive the driving force from the first sliding door mechanism 1 and transmit this force to the door panel 3 to drive it to move.

[0056] In this embodiment, Figures 2 to 5 As shown, the second mounting groove 22 is located outside the box door 2, and the second sliding door mechanism 10 is vertically arranged in the second mounting groove 22. The third guide rail 1011 is coaxially arranged with the first guide rail 131, and the third guide rail 1011 and the fourth guide rail 1012 are arranged in parallel and side by side, so that when the first slider 11 moves on the first guide rail 131, the connecting rod 8 is connected to drive the third slider 102 to move synchronously on the third guide rail 1011, so as to complete the adjustment of the positions of the first slider 11 and the third slider 102 through a single traction mechanism 9, so that the door panel 3 can move under the drive of the second slider 12 and the fourth slider 103.

[0057] In order to facilitate the placement of the first sliding door mechanism 1, the second sliding door mechanism 10 and the connecting rod 8, as shown in FIG. Figures 1 to 3 As shown, a third mounting groove 23 is provided in the box door 2, and the third mounting groove 23 is connected to the first mounting groove 21 and the second mounting groove 22, and a part of the connecting rod 8 is movably arranged in the third mounting groove 23; one end of the connecting rod 8 is located in the first mounting groove 21 and is connected to the second slider 12; the other end of the connecting rod 8 is located in the second mounting groove 22 and is connected to the third slider.

[0058] In actual applications, due to factors such as machine tool accuracy, tool wear, and material non-uniformity, there will be certain errors in the processing of the first guide rail 131, the second guide rail 132, the third guide rail 1011, the fourth guide rail 1012, the first base 13, and the second base 101. These errors may include dimensional errors (such as deviations in length, width, and height), shape errors (such as straightness, flatness, roundness, etc.), and position errors (such as coaxiality, parallelism, and verticality). The parallelism between the first guide rail 131 and the second guide rail 132 is evaluated by measuring the relative position deviation between them. This deviation needs to be controlled within a certain tolerance range to ensure the smooth sliding of the corresponding slider and the stable operation of the system.

[0059] That is to say, in this embodiment, the directions of the guide rails, whether parallel or vertical, should not be strictly defined in a geometric sense. At least the manufacturing and installation errors should be considered, and errors of plus or minus 10° should be understood as within the scope of protection of the patent.

[0060] In one example, a second ball and a second support member are provided between the third slider 102 and the third guide rail 1011 and between the fourth slider 103 and the fourth guide rail 1012. The second support member is provided with a second rolling notch, and the second ball is rollably disposed in the second rolling notch.

[0061] In this embodiment, a second support frame is set between the third slider and the third guide rail 1011 and between the fourth slider 103 and the fourth guide rail 1012, and the second support frame is used to limit the second ball therein to prevent the second ball from shifting when rolling, so that the sliding of the third slider is more stable and reliable.

[0062] Generally, the second rolling notch is an arc notch that matches the shape of the second ball. The arc notch is provided to enhance the limiting effect on the second ball, and when the second rolling notch contacts the second ball, the force receiving area is larger and the force is more dispersed, which can reduce the wear between the second support frame and the second ball and extend the service life.

[0063] In this embodiment, the connecting rod 8 is a key component connecting the first sliding door mechanism 1 and the second sliding door mechanism 10, and its placement method is very important. In this embodiment, a part of the connecting rod 8 is movably arranged in the third mounting groove 23. This design enables the connecting rod 8 to flexibly adapt to the relative position changes of the components in the first sliding door mechanism 1 and the second sliding door mechanism 10 during the movement, thereby ensuring the stability and reliability of the connection. One end of the connecting rod 8 is located in the first mounting groove 21 and is tightly connected to the first slider 11 in the first sliding door mechanism 1. In this way, when the first sliding door mechanism 1 is subjected to a driving force, the force can be transmitted to the second sliding door mechanism 10 through the connecting rod 8. At the same time, the other end of the connecting rod 8 is located in the second mounting groove 22 and is connected to the third slider 102 in the second sliding door mechanism 10. In this way, the second sliding door mechanism 10 can receive the driving force from the first sliding door mechanism 1 and cooperate with the driving door panel 3 to move accordingly. The connecting rod 8 is arranged by the connection design of the third mounting groove 23, which ensures that the connection between the components is stable and smooth, thereby improving the stability and reliability of the entire door assembly. Moreover, the third mounting groove 23 is provided to make the layout of the first sliding door mechanism 1 , the second sliding door mechanism 10 , the connecting rod 8 and other components more reasonable and compact, thereby saving the space inside the door 2 .

[0064] In one embodiment of the present application, Figures 1 to 4 As shown, the two ends of the traction mechanism 9 are rotatably connected to the box body 4 and the first slider 11 respectively. Specifically, the traction mechanism 9 includes a traction rod, a first rotating shaft fixing seat and a second rotating shaft fixing seat. The traction rod can be a linear guide rod or a curved guide rod, which can be adjusted according to specific needs. The first rotating shaft fixing seat is connected to the first slider 11, and the second rotating shaft fixing seat is used to connect to the box body 4. One end of the traction rod is rotatably connected to the first rotating shaft fixing seat, and the other end of the traction rod is rotatably connected to the second rotating shaft fixing seat.

[0065] In this embodiment, the first rotating shaft fixing seat and the second rotating shaft fixing seat are respectively fixed to the first slider 11 and the box body 4, and the first rotating shaft fixing seat and the second rotating shaft fixing seat are connected by a traction rod. When the box door 2 rotates relative to the box body 4, the angle between the box body 4 and the box door 2 changes, so that the first slider 11 is pulled through the transmission connection of the traction rod, the first rotating shaft fixing seat and the second rotating shaft fixing seat, so that the first slider 11 slides on the first base 13, and drives the second slider 12 to slide to realize the movement of the door panel 3 relative to the box door 2.

[0066] In some embodiments, Figure 4As shown, a fourth mounting groove 24 is further provided on the outer side of the door panel 3, and the door body assembly further includes: a driven guide rail mechanism 14. The driven guide rail mechanism 14 is provided in the fourth mounting groove 24, and the driven guide rail mechanism 14 is connected to the door panel 3, and is configured to cooperate and guide the door panel 3 to move relative to the width direction of the door 2 during the process of opening or closing the door 2.

[0067] Specifically, the fourth mounting groove 24 provides a mounting space for the driven guide rail mechanism 14. The main function of the driven guide rail mechanism 14 is to guide the door panel 3 to move relative to the width direction of the door 2 during the opening or closing process of the door 2. This design allows the door panel 3 to be further guided by the driven guide rail mechanism 14 on the basis of being driven by the first sliding door mechanism 1 and the second sliding door mechanism 10, thereby increasing the stability of the door panel 3 when moving relative to the door 2.

[0068] The driven guide rail mechanism 14 includes: a third base and a fifth slider. A fifth guide rail is formed on the outer side of the third base; the fifth slider is slidably arranged on the fifth guide rail. In this embodiment, the fifth base serves as the main body of the driven guide rail mechanism 14, and the third base provides a stable installation foundation and a sliding track. The fifth guide rail formed by the fifth base is the sliding path of the fifth slider. The fifth slider is directly connected to the door panel 3. During the sliding process, the fifth slider will move linearly along the fifth guide rail, thereby driving the door panel 3 to move accordingly. Since the fifth slider is directly connected to the door panel 3, its sliding performance and stability will directly affect the movement effect of the door panel 3.

[0069] Based on the above embodiments, in some embodiments, one of the first mounting groove 21 and the fourth mounting groove 24 is disposed at the top of the outer side of the door 2 , and the other is disposed at the bottom of the outer side of the door 2 .

[0070] Generally, the first mounting groove 21, the second mounting groove 22, and the third mounting groove 23 are all arranged at the top of the outer side of the box door 2, and are used to cooperate with the first sliding door mechanism 1, the second sliding door mechanism 10, and the connecting rod 8. The fourth mounting groove 24 is arranged at the bottom of the outer side of the box door 2, and is used to arrange the driven guide rail mechanism 14. By arranging the first sliding door mechanism 1, the second sliding door mechanism 10, the connecting rod 8, and the driven guide rail mechanism 14 at the same time, the upper part of the door panel 3 is driven by the first sliding door mechanism 1 and the second sliding door mechanism 10, and the lower part of the door panel 3 is guided by the driven guide rail mechanism 14, so that the door panel 3 can operate stably during the sliding process relative to the width direction of the box door 2.

[0071] In another embodiment of the present application, Figures 1 to 6As shown, a refrigeration device is provided, comprising: a box body 4 and a door assembly as provided in any of the above embodiments. The box body 4 is formed with a storage space, and the box door 2 is rotatably connected to the box body 4, suitable for opening or closing the storage space. The door assembly is applied to the refrigeration device, comprising: a box door 2, a door panel 3, a traction mechanism 9 and a first sliding door mechanism 1. The box door 2 is rotatably connected to the box body 4, suitable for opening or closing the storage space of the box body 4, and a first mounting groove 21 is provided on the outer side of the box door 2; the door panel 3 is slidably arranged on the outer side of the box door 2; the first sliding door mechanism 1 is arranged in the first mounting groove 21, one end of the first sliding door mechanism 1 is transmission-connected to the box body 4 through the traction mechanism 9, and the other end of the first sliding door mechanism 1 is connected to the door panel 3. In the process of opening or closing the box door 2, the traction mechanism 9 drives the first sliding door mechanism 1, so that the first sliding door mechanism 1 drives the door panel 3 to move relative to the width direction of the box door 2.

[0072] Specifically, when the door 2 is rotated to open outside the box body 4, the first sliding door mechanism 1 drives the door panel 3 to slide away from the hinge 5, thereby preventing the door panel 3 from interfering with obstacles outside. When the door 2 is rotated to close to the box body 4, the first sliding door mechanism 1 drives the door panel 3 to slide toward the hinge 5, thereby preventing the door panel 3 from interfering with obstacles after closing.

[0073] In this embodiment, a door panel 3 is arranged on the cabinet door 2. When the refrigeration device is embedded and arranged in a groove-shaped space, or when it is arranged between two cabinets, the door panel 3 can be arranged flush with the cabinets on the side walls or both sides of the groove to reduce the gap between the refrigeration device and the adjacent walls or cabinets, which is more beautiful.

[0074] In some embodiments, Figure 5 and Figure 6 As shown, the door assembly and the box 4 are used to be arranged in the installation space formed between the first cabinet 6 and the second cabinet 7. The outer side of the installation space is provided with an opening. This design allows the door assembly and the box 4 to be integrally embedded in the cabinet. In the process of the box door 2 passing through the opening to control the opening or closing of the storage space, the first sliding door mechanism 1 is configured to drive the door panel 3 to move a preset distance on the box door 2 in a direction away from or close to the hinge 5, so that the door panel 3 avoids the side walls of the first cabinet 6 and the second cabinet 7.

[0075] In the process of the door 2 passing through the opening to control the opening or closing of the storage space, the first sliding door mechanism 1 is configured to drive the door panel 3 to move a preset distance on the door 2 in a direction away from or close to the hinge 5. In order to avoid interference between the door panel 3 and the side walls of the first cabinet 6 and the second cabinet 7, the door panel 3 can be opened or closed smoothly through the movement of the preset distance without colliding or getting stuck with the side walls of the cabinets.

[0076] For example, Figure 5 and Figure 6 As shown, during the opening of the door 2, the first sliding door mechanism 1 drives the door panel 3 to move a preset distance along the door 2 in a direction away from the hinge 5. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet 7, so that the door 2 can be fully opened, which is convenient for users to store and retrieve items.

[0077] Similarly, when the door 2 is closed, the first sliding door mechanism 1 drives the door panel 3 to move a preset distance along the door 2 toward the hinge 5. In this way, the door panel 3 can smoothly avoid the side wall of the first cabinet 6, so that the door 2 can be completely closed, maintaining the overall aesthetics and sealing.

[0078] 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 is described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications or equivalent substitutions 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 be included in the scope of the claims of the present invention.
