[0003] This application relates to the field of household appliances, and more particularly to a door assembly and a refrigeration device. Background Technology

[0004] With the increasing demand for integrated home appliances and furniture, built-in design of home appliances has become a trend. However, in pursuit of a better integrated home effect, it is sometimes necessary to fix a door panel on the cabinet door surface, and higher requirements are placed on the gap between the built-in appliance and the cabinet side wall to further improve the integrated effect.

[0049] The door assembly and refrigeration device of this application are described below with reference to Figures 1 to 8. 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 devices. The refrigeration device of this application is applied, for example, to a refrigerator; however, it should be understood that the refrigeration device of this application can also be applied to a freezer or any other suitable device.

[0050] In one embodiment of this application, as shown in Figures 1 to 5, the door assembly is applied to a refrigeration device. The refrigeration device includes a housing 4, and the door assembly includes: a door 2, a door panel 3, a traction mechanism 9, and an active sliding door mechanism 1. The door 2 is rotatably connected to the housing 4 of the refrigeration device and is suitable for opening or closing the storage space of the housing 4. The top surface of the door 2 is provided with a first mounting groove 21. The door panel 3 is slidably disposed on the outside of the door 2. The active sliding door mechanism 1 is disposed in the first mounting groove 21. One end of the active sliding door mechanism 1 is connected to the housing 4 via the traction mechanism 9, and the other end of the active sliding door mechanism 1 is connected to the door panel 3. During the opening or closing of the door 2, the traction mechanism 9 drives the first active sliding door mechanism 1, causing the active sliding door mechanism 1 to drive the door panel 3 to move relative to the width direction of the door 2.

[0051] In this embodiment, to assemble the active sliding door mechanism 1 and reduce the thickness of the door 2, a first mounting groove 21 is designed on the top surface of the door 2. The first mounting groove 21 provides an installation position and space for the active sliding door mechanism 1. To allow the door panel 3 to avoid obstacles such as side walls and objects, the door panel 3 is slidably mounted on the outside of the door 2. The traction mechanism 9 is mainly used to connect the box body 4 and the active sliding door mechanism 1, and is used to transmit power, responsible for converting the movement of the box body 4 (such as opening or closing) into the driving force of the active sliding door mechanism 1.

[0052] When the user rotates the door 2, the traction mechanism 9, driven by the relative movement between the door 2 and the box body 4, drives the active sliding door mechanism 1 to perform the corresponding action. The active sliding door mechanism 1 is disposed in the first mounting groove 21 on the top surface of the door 2. One end of the active sliding door mechanism 1 is connected to the box body 4 via 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 active 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 side walls and objects.

[0053] According to the door assembly of this application embodiment, one end of the active sliding door mechanism 1 is connected to the housing 4 via a traction mechanism 9, and the other end of the active sliding door mechanism 1 is connected to the door panel 3. This allows the active sliding door mechanism 1 to drive the door panel 3 to move relative to the width of the housing door 2 during opening or closing, thus preventing the door panel 3 from obstructing side walls, objects, or other obstacles. In this embodiment, by placing the active sliding door mechanism 1 in the first mounting groove 21 on the top surface of the housing door 2, the door panel 3 is slidably positioned on the outside of the housing door 2, reducing the thickness of the housing door 2 compared to a side-mounted solution.

[0054] In some embodiments, as shown in Figures 1 to 5, the active sliding door mechanism 1 is horizontally disposed in the first mounting groove 21. The active sliding door mechanism 1 includes: a first base 13, a first slider 11, a second slider 12, and a connector. A first guide rail 131 is formed on the inner side of the first base 13, and a second guide rail 132 is formed on the outer side. The first slider 11 is slidably disposed on the first guide rail 131 and is used for transmission connection with the housing 4 through the traction mechanism 9. The second slider 12 is slidably disposed on the second guide rail 132 and is connected to the door panel 3. The two ends of the connector 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 connector, so as to drive the door panel 3 to move relative to the width direction of the housing door 2.

[0055] Specifically, as shown in Figure 5, the first guide rail 131 is located inside the first base 13, providing a sliding track for the first slider 11. The second guide rail 132 is located outside 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 mounted on the first guide rail 131 and is connected to the housing 4 via a transmission connection. The second slider 12 is slidably mounted on the second guide rail 132 and is connected to the door panel 3. The two ends of the connector are respectively connected to the first slider 11 and the second slider 12.

[0056] 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 driving force. Since the two ends of the connector are fixed to the first slider 11 and the second slider 12 respectively, by reasonably setting the extension direction of the connector, the connector will drive the second slider 12 to move in the opposite direction on the second guide rail 132. This characteristic of synchronous and opposite movement allows the door panel 3 to slide relative to the width direction of the box body 4.

[0057] The active sliding door mechanism 1 provided in this application has a first slider 11 and a second slider 12 respectively set on the first guide rail 131 and the second guide rail 132, and the first slider 11 and the second slider 12 are connected by a connector, so that when the first slider 11 moves, it can drive the second slider 12 to move in the opposite direction. Thus, when the first slider 11 is connected to the housing 4 and the second slider 12 is connected to the door panel 3, the active sliding door mechanism 1 can drive the door panel 3 to slide relative to the width direction of the housing door 2. This allows the door panel 3 to avoid obstacles such as side walls and objects during the closing or opening of the housing door 2, so as to meet the user's needs in different scenarios.

[0058] It should be noted that in practical applications, the design 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.

[0059] From a materials perspective, the first slider 11 and the second slider 12 can be made of materials with high wear resistance, low coefficient of friction, and good stability, such as metal alloys, engineering plastics, or special lubricating materials. The selection of these materials aims to improve the durability of the sliders, reduce wear and noise during sliding, and ensure smooth sliding.

[0060] 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 planar contact, ball contact, or sliding bearing contact. Each of these different contact methods has its advantages and disadvantages. For example, ball contact can reduce friction and wear, but it is more expensive; while planar contact has a simple structure, but may require more frequent lubrication and maintenance. Therefore, factors such as usage conditions, cost-effectiveness, and ease of maintenance should be comprehensively considered when making a selection.

[0061] In addition, to enhance the load-bearing capacity and stability of the sliders, reinforcing ribs, support plates, or other auxiliary structures can be added to the first slider 11 and the second slider 12. These structures can increase the rigidity and deformation resistance of the sliders, ensuring stable sliding performance when bearing the weight of the door panel 3 and external forces.

[0062] In some embodiments, as shown in FIG5, the connector is a rope, and the connector includes a first connector and a second connector. The first connector passes around one end of the first base 13, and its two ends are respectively connected to one end of the first slider 11 and the second slider 12; the second connector passes around the other end of the first base 13, and its two ends are respectively connected to the other ends of the first slider 11 and the second slider 12.

[0063] Specifically, one end of the first connector is fixed to a predetermined position of the first slider 11, then passes around a specific part of the first base 13 (such as a pulley or guide device on the base), and finally connects to the corresponding position of the second slider 12. In this way, when the first slider 11 moves on the first guide rail 131, the first connector can smoothly transmit this movement and drive the second slider 12 to move in the opposite direction on the second guide rail 132.

[0064] Similarly, the second connector also bypasses the other end of the first base 13, but its path differs from that of the first connector to ensure balance and stability between the two sliders. One end of the second connector is fixed to another predetermined position of the first slider 11 (opposite to the connection point of the first connector), bypasses the other side of the first base 13, and finally connects to the other end of the second slider 12. This dual-connector design not only enhances the reliability of the connection but also makes the entire active sliding door mechanism 1 more stable and smooth during operation.

[0065] The performance of the active sliding door mechanism 1 can be further optimized by adjusting the bypass paths and fixing point positions of the first and second connectors on the first base 13. For example, the tension of the rope can be adjusted to ensure the synchronicity and consistency of the first slider 11 and the second slider 12 during movement.

[0066] In this embodiment, as shown in Figures 2 to 5, the first mounting groove 21 is located on the top surface of the door 2. To reduce the space occupied by the active sliding door mechanism 1, the active sliding door mechanism 1 is horizontally arranged in the first mounting groove 21, making the structure of the entire door assembly more compact. The first guide rail 131 and the second guide rail 132 are arranged parallel to each other. This arrangement not only enhances the stability and load-bearing capacity of the active sliding door mechanism 1, but also makes the movement of the first slider 11 and the second slider 12 smoother and more stable. The first guide rail 131 faces inward, which makes it easier for the first slider 11 on the first guide rail 131 to connect with the traction mechanism 9. The traction mechanism 9 is usually located inside the housing 4 or near the inside of the door 2. Therefore, the orientation of the first guide rail 131 helps to reduce the length and complexity of the connection lines and improve the reliability and efficiency of the connection. The second guide rail 132 faces outward, which makes it easier for the second slider 12 on the second guide rail 132 to connect with the door panel 3. Since the door panel 3 is a component located on the outside of the door 2, the orientation of the second guide rail 132 is conducive to achieving a stable connection between the door panel 3 and the active sliding door mechanism 1.

[0067] In practical applications, due to factors such as machine tool precision, tool wear, and material inhomogeneity, the machining of the first guide rail 131 and the second guide rail 132 will have certain errors. These errors may include dimensional errors (such as deviations in length, width, and height), shape errors (such as straightness, flatness, and roundness), and positional errors (such as coaxiality, parallelism, and perpendicularity). The parallelism between the first guide rail 131 and the second guide rail 132 is evaluated by measuring their relative positional deviation. This deviation needs to be controlled within a certain tolerance range to ensure smooth sliding of the corresponding sliders and stable operation of the system.

[0068] In other words, the direction of the guide rail in this embodiment, whether it is parallel or perpendicular, should not be strictly geometric. At least manufacturing and installation errors should be taken into account, and an error of ±10° should be understood as being within the scope of patent protection.

[0069] In some embodiments, as shown in FIG6, a first ball 15 and a first support member 14 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 14 is provided with a first rolling notch, and the first ball 15 is rotatably disposed in the first rolling notch.

[0070] In this embodiment, a first support frame is provided between the first slider 11 and the first guide rail 131, and the second slider 12 and the second guide rail 132 are supported by the first support frame to limit the first ball 15 and prevent the first ball 15 from deviating when rolling, so that the sliding of the first slider 11 and the second slider 12 is more stable and reliable.

[0071] Specifically, the first rolling notch is an arc-shaped notch that matches the shape of the first ball 15. By setting the arc-shaped notch, the limiting effect on the first ball 15 is improved. Moreover, when the first rolling notch contacts the first ball 15, the force-bearing area is larger and the force is more dispersed, which can reduce the wear between the first support frame and the first ball 15 and extend the service life.

[0072] In some embodiments, as shown in Figures 1 to 5, the top surface of the door 2 is provided with a second mounting groove 22; the door assembly further includes a driven sliding door mechanism 10 and a connecting rod 8; the driven sliding door mechanism 10 is disposed in the second mounting groove 22, the driven sliding door mechanism 10 is connected to the second slider 12 through the connecting rod 8, and the driven sliding door mechanism 10 is connected to the door panel 3. The driven sliding door mechanism 10 is configured to cooperate with the active sliding door mechanism 1 to drive the door panel 3 to move relative to the width direction of the door 2 during the opening or closing of the door 2.

[0073] Specifically, a second mounting groove 22 is provided on the top surface of the door 2, providing mounting space for the driven sliding door mechanism 10. The main function of the driven sliding door mechanism 10 is to guide the door panel 3 to move relative to the width direction of the door 2 during the opening or closing process. The connecting rod 8, as a component connecting the driven sliding door mechanism 10 and the second slider 12, plays a role in transmitting force and motion. When the driven sliding door mechanism 10 is driven by the second slider 12 on the active sliding door mechanism 1, the driven sliding door mechanism 10 can cooperate with the guide door panel 3 to move. This design allows the door panel 3 to be further guided by the driven sliding door mechanism 10 on the basis of being driven by the active sliding door mechanism 1, thereby increasing the stability of the door panel 3 when moving relative to the door 2.

[0074] In some embodiments, as shown in Figures 1 to 5, the driven sliding door mechanism 10 is horizontally disposed in the second mounting groove 22, and includes a second base 101 and a third slider 102. A third guide rail 1011 is formed on the outer side of the second base 101; the third slider 102 is slidably disposed on the third guide rail 1011, connected to the second slider 12 via a connecting rod 8, and connected to the door panel 3.

[0075] In this embodiment, the second base 101 serves as the main body of the driven sliding door mechanism 10, providing a stable mounting base and sliding track. The third guide rail 1011 formed by the second base 101 is the sliding path of the third slider 102. The third slider 102 is slidably mounted on the third guide rail 1011, directly connected to the door panel 3, and connected to the second slider 12 via the connecting rod 8. During sliding, the third slider 102 moves linearly along the third guide rail 1011, thereby driving the door panel 3 to move accordingly. Since the third slider 102 is directly connected to the door panel 3, its sliding performance and stability directly affect the movement effect of the door panel 3. The connecting rod 8 connects the third slider 102 and the second slider 12, enabling the driven sliding door mechanism 10 to receive the driving force from the active sliding door mechanism 1 and transmit this force to the door panel 3, driving it to move. At the same time, the connecting rod 8 also plays a certain role in buffering and adjustment, making the movement of the door panel 3 more stable and smooth.

[0076] In this embodiment, as shown in Figures 2 to 5, the second mounting groove 22 is located on the top surface of the door 2, and the driven sliding door mechanism 10 is horizontally arranged in the second mounting groove 22. The third guide rail 1011 is coaxially arranged with the second guide rail 132, so that when the second slider 12 moves on the second guide rail 132, the connecting rod 8 drives the third slider 102 to move synchronously on the third guide rail 1011, making the movement of the second slider 12 and the third slider 102 more stable and smooth. The third guide rail 1011 faces outward, which makes it easier for the third slider 102 on the third guide rail 1011 to connect with the door panel 3, which is beneficial to achieving a stable connection between the door panel 3 and the driven sliding door mechanism 10.

[0077] To facilitate the installation of the active sliding door mechanism 1, the driven sliding door mechanism 10, and the connecting rod 8, as shown in Figures 1 to 3, the door 2 is provided with a third mounting groove 23, which is connected to the first mounting groove 21 and the second mounting groove 22. A portion of the connecting rod 8 is movably disposed 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 102.

[0078] In one example, a second ball and a second support are provided between the third slider 102 and the third guide rail 1011. The second support is provided with a second rolling notch, and the second ball is rotatably disposed in the second rolling notch.

[0079] In this embodiment, by setting a second support frame between the third slider 102 and the third guide rail 1011, the second support frame is used to limit the second ball, preventing the second ball from deviating during rolling, making the sliding of the third slider 102 more stable and reliable.

[0080] Typically, the second rolling notch is an arc-shaped notch that matches the shape of the second ball. By setting an arc-shaped notch, the limiting effect on the second ball is improved. Moreover, when the second rolling notch contacts the second ball, the force-bearing 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.

[0081] In this embodiment, the connecting rod 8, as a key component connecting the active sliding door mechanism 1 and the driven sliding door mechanism 10, is crucially positioned. In this embodiment, a portion of the connecting rod 8 is movably disposed in the third mounting groove 23. This design allows the connecting rod 8 to flexibly adapt to changes in the relative positions of the components in the active sliding door mechanism 1 and the driven sliding door mechanism 10 during movement, 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 second slider 12 in the active sliding door mechanism 1. Thus, when the active sliding door mechanism 1 is subjected to a driving force, this force can be transmitted to the driven sliding door mechanism 10 through the connecting rod 8. Simultaneously, 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 driven sliding door mechanism 10. In this way, the driven sliding door mechanism 10 can receive the driving force from the active sliding door mechanism 1 and cooperate with the drive door panel 3 to move accordingly. The connection design of the third mounting slot 23 for mounting the connecting rod 8 ensures a stable and smooth connection between the components, improving the stability and reliability of the entire door assembly. Furthermore, the third mounting slot 23 allows for a more rational and compact layout of the active sliding door mechanism 1, the driven sliding door mechanism 10, and the connecting rod 8, saving space inside the door 2.

[0082] In one embodiment of this application, as shown in Figures 1 to 5, the two ends of the traction mechanism 9 are rotatably connected to the housing 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 straight 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 housing 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.

[0083] In this embodiment, by fixing the first rotating shaft fixing seat and the second rotating shaft fixing seat to the first slider 11 and the box body 4 respectively, and connecting the first rotating shaft fixing seat and the second rotating shaft fixing seat through 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, thereby pulling the first slider 11 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.

[0084] In another embodiment of this application, as shown in Figures 1 to 8, a refrigeration device is provided, including: a housing 4 and a door assembly as provided in any of the above embodiments. The housing 4 forms a storage space, and a door 2 is rotatably connected to the housing 4, suitable for opening or closing the storage space. The door assembly, applied to the refrigeration device, includes: a door 2, a door panel 3, a traction mechanism 9, and an active sliding door mechanism 1. The door 2 is rotatably connected to the housing 4, suitable for opening or closing the storage space of the housing 4, and the top surface of the door 2 is provided with a first mounting groove 21; the door panel 3 is slidably disposed on the outside of the door 2; the active sliding door mechanism 1 is disposed in the first mounting groove 21, one end of the active sliding door mechanism 1 is connected to the housing 4 via the traction mechanism 9, and the other end of the active sliding door mechanism 1 is connected to the door panel 3. The active sliding door mechanism 1 is configured to drive 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.

[0085] Specifically, during the process of the door 2 rotating outward to open the box body 4, the active 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 on the outside. During the process of the door 2 rotating to close to one side of the box body 4, the active sliding door mechanism 1 drives the door panel 3 to slide closer to the hinge 5 through the traction mechanism 9, thereby preventing the closed door panel 3 from interfering with obstacles.

[0086] In this embodiment, when a door panel 3 is installed on the cabinet door 2 and the refrigeration equipment is embedded in a recessed space or between two cabinets, the door panel 3 can be installed flush with the cabinets on the side wall or sides of the recess to reduce the gap between the refrigeration equipment and the adjacent wall or cabinet, making it more aesthetically pleasing.

[0087] In some embodiments, as shown in Figures 7 and 8, the door assembly and the cabinet 4 are disposed within an installation space formed between the first cabinet 6 and the second cabinet 7. An opening is provided on the outer side of the installation space, allowing the door assembly and the cabinet 4 to be integrally embedded into the cabinet. During the process of the cabinet door 2 passing through the opening to control the opening or closing of the storage space, the traction mechanism 9 drives the first active sliding door mechanism 1, causing the active sliding door mechanism 1 to drive the door panel 3 to move a preset distance relative to the width direction of the cabinet door 2, so that the door panel 3 avoids the side walls of the first cabinet 6 and the second cabinet 7.

[0088] During the opening or closing of the storage space controlled by the opening through the door 2, the traction mechanism 9 drives the first active sliding door mechanism 1, which is configured to drive the door panel 3 to move a preset distance away from or towards the hinge 5 on the door 2. In order to avoid interference between the door panel 3 and the side walls of the first cabinet 6 and the second cabinet 7, and to ensure that the door panel 3 can open or close smoothly without colliding or getting stuck with the side walls of the cabinets, the door panel 3 can move a preset distance.

[0089] For example, as shown in Figures 7 and 8, during the opening of the cabinet door 2, the active sliding door mechanism 1, in conjunction with the traction mechanism 9, drives the door panel 3 to move a preset distance away from the hinge 5 along the cabinet door 2. In this way, the door panel 3 can smoothly avoid the side wall of the second cabinet 7, allowing the cabinet door 2 to be fully opened, making it convenient for users to store and retrieve items.

[0090] Similarly, during the closing process of the cabinet door 2, the active sliding door mechanism 1, in conjunction with the traction mechanism 9, drives the door panel 3 to move a preset distance along the cabinet door 2 towards the hinge 5. In this way, the door panel 3 can smoothly avoid the side wall of the first cabinet 6, allowing the cabinet door 2 to be completely closed, maintaining overall aesthetics and sealing.

[0091] Finally, it should be noted that the above embodiments are for illustrative purposes only and are not intended to limit the scope of 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 scope of the technical solutions of this application and should be covered by the scope of the claims of this application.
