Door components and refrigeration equipment

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese patent application No. 202411187356.0, filed on August 26, 2024, entitled "Door Assembly and Refrigeration Equipment", which is incorporated herein by reference in its entirety. Technical Field

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

[0004] With the growing demand for the integration of home appliances and home furnishings, embedded design of home appliances has become a trend.

[0005] However, in pursuit of a better integrated home aesthetic, it is sometimes necessary to attach additional door panels to the cabinet door surface. Furthermore, a higher clearance is required between the embedded appliances and the cabinet sidewalls to further enhance the integrated effect. This results in the door assembly with the panel interfering with the sidewalls of the cabinet installation space during opening and closing when the appliance is embedded in the cabinet, preventing the appliance door assembly from opening or closing properly. Summary of the Invention

[0006] This application aims to at least solve one of the technical problems existing in the related art. To this end, this application proposes a door assembly and a refrigeration device to solve the problem that the door assembly with a door panel may interfere with the side of the installation space during the opening and closing process, causing the door assembly of the appliance to be unable to open or close normally.

[0009] The door panel is slidably disposed on the outside of the cabinet door;

[0010] The enclosure includes a traction mechanism, an active sliding door mechanism, and a first driven sliding door mechanism. The first driven sliding door mechanism and the active sliding door mechanism are coaxially mounted on the door and are both slidably connected to the door panel. The active sliding door mechanism is connected to the enclosure via the traction mechanism. The active sliding door mechanism is configured such that, during the opening or closing of the enclosure door, the traction mechanism drives the active sliding door mechanism, causing the active sliding door mechanism to drive the door panel to move relative to the width direction of the enclosure door. The first driven sliding door mechanism is configured to cooperate in guiding the door panel to move relative to the enclosure door.

[0011] In some embodiments, both the first driven sliding door mechanism and the active sliding door mechanism are arranged along the width direction of the door and are located at the top or bottom of the door.

[0012] In some embodiments, the door assembly further includes:

[0013] The second driven sliding door mechanism is arranged along the width direction of the door and is arranged on the door off-axis from the active sliding door mechanism; the first driven sliding door mechanism and the second driven sliding door mechanism are configured to cooperate in guiding the door panel to move relative to the door during the opening or closing of the door.

[0014] In some embodiments, the active sliding door mechanism and the first driven sliding door mechanism are disposed at the top of the cabinet door, and the second driven sliding door mechanism is disposed at the bottom of the cabinet door.

[0015] In some embodiments, the active sliding door mechanism and the first driven sliding door mechanism are disposed at the bottom of the cabinet door, and the second driven sliding door mechanism is disposed at the top of the cabinet door.

[0016] The refrigeration device according to an embodiment of this application includes:

[0017] The box-shaped structure forms a storage space;

[0018] As described in any of the above-mentioned door components, the cabinet door is rotatably connected to the cabinet and is adapted to open or close the storage space.

[0019] In some embodiments, the enclosure has at least two storage spaces, and the door assembly has multiple components, each corresponding to one of the storage spaces, so as to drive the door panel to move relative to the corresponding door during the opening or closing of any of the doors.

[0020] In some embodiments, the enclosure forms a first storage space and a second storage space, and there are two door components, namely a first door component and a second door component;

[0021] The door of the first door assembly is rotatably connected to the box body and is adapted to open or close the first storage space; the door of the second door assembly is rotatably connected to the box body and is adapted to open or close the second storage space.

[0022] In some embodiments, the first door assembly and the second door assembly are arranged sequentially along the height direction of the door.

[0023] In some embodiments, the first door assembly further includes a first driven sliding door mechanism and a second driven sliding door mechanism, and the second door assembly further includes a first driven sliding door mechanism and a second driven sliding door mechanism;

[0025] The above-described one or more technical solutions in the embodiments of this application have at least one of the following technical effects:

[0026] According to the door assembly of this application embodiment, the door is rotatably connected to the box body, and the door panel is slidably disposed on the outside of the door. An active sliding door mechanism is provided on the door, which is connected to both the door and the door panel. During the process of the door rotating open or close relative to the box body, the box body drives the active sliding door mechanism through a traction mechanism, causing the active sliding door mechanism to drive the door panel to slide relative to the width direction of the door. This allows the door panel to avoid obstacles such as side walls and objects during the opening or closing of the door, thus meeting the user's needs in different scenarios. At the same time, by setting a first driven sliding door mechanism to support and assist the sliding of the door panel, the sliding of the door panel is made more stable and smooth, resulting in a better user experience.

[0027] According to the refrigeration equipment of the present application embodiment, the above-mentioned door assembly is provided, so that during the process of the door rotating to open or close relative to the cabinet, the active sliding door mechanism of the door assembly can drive the door panel to slide relative to the width direction of the door. During the sliding of the door panel, the first driven sliding door mechanism of the door assembly can support and assist the sliding of the door panel, so that the door panel can avoid obstacles such as side walls and objects during the closing or opening of the cabinet, and avoid interference between the door panel and obstacles that would affect the rotation of the cabinet door, so as to meet the user's usage needs in different scenarios.

[0028] Furthermore, by setting the first driven sliding door mechanism, the active sliding door mechanism, and the second driven sliding door mechanism at positions close to the upper and lower ends of the door, the sliding of the door panel can be better supported and assisted, and the door panel can be limited to prevent it from shaking or swaying.

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.

[0060] The door assembly and refrigeration device of this application are described below with reference to Figures 1 to 23. 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.

[0061] In one embodiment of this application, as shown in Figures 1 and 2, a door assembly is applied to a refrigeration device. The refrigeration device includes a housing 1, and the door assembly includes: a door 2, rotatably connected to the housing 1, suitable for opening or closing the storage space of the housing 1; a door panel 21, slidably disposed on the outside of the door 2; a traction mechanism, an active sliding door mechanism 7, and a first driven sliding door mechanism 8. The first driven sliding door mechanism 8 is coaxially disposed on the door 2 with the active sliding door mechanism 7, and both are slidably connected to the door panel 21. The active sliding door mechanism 7 is connected to the housing 1 through the traction mechanism. The active sliding door mechanism 7 is configured such that during the opening or closing of the door 2, the traction mechanism drives the active sliding door mechanism 7, causing the active sliding door mechanism 7 to drive the door panel 21 to move relative to the width direction of the door 2. The first driven sliding door mechanism 8 is configured to cooperate in guiding the door panel 21 to move relative to the door 2.

[0062] Both the active sliding door mechanism 7 and the first driven sliding door mechanism 8 can include relatively sliding movable components such as sliders and slide rails. The two relatively sliding components of the active sliding door mechanism 7 are connected to the cabinet door 2 and the door panel 21 respectively through appropriate connection methods (such as bolt connection, welding, etc.). At the same time, the active sliding door mechanism 7 is connected to the cabinet body 1 through a traction mechanism. In this way, when the cabinet door 2 rotates to open and close, the cabinet body 1 rotates relative to the cabinet door 2, thereby driving the active sliding door mechanism 7 through the traction mechanism. This allows the active sliding door mechanism 7 to drive the door panel 21 to move in the width direction relative to the cabinet door 2 during the rotation of the cabinet door 2 (as shown by the double arrows in Figure 1) to move as far away as possible from the walls, objects, and other obstacles on the side door of the cabinet body 1, so as to avoid these obstacles blocking the door panel 21 and affecting the rotation of the cabinet door 2, thus preventing the cabinet door 2 from being unable to open or close normally.

[0063] Understandably, the width direction of the door 2 is parallel to the plane on which the door 2 is located and perpendicular to the pivot of the door 2, so that the door panel 21 can be away from or close to the pivot of the door 2.

[0064] It should be noted that the parallel and perpendicular relationships in this application need to take into account the installation errors between various components. An error of ±10° should be understood as being within the scope of protection of the patent.

[0065] Specifically, during the process of the door 2 rotating outwards to open towards the outside of the box body 1 (as shown by the arc arrow in Figure 1), the active sliding door mechanism 7 drives the door panel 21 to slide away from the first hinge 4, thereby preventing the door panel 21 from interfering with obstacles on the outside. During the process of the door 2 rotating to close towards the side of the box body 1, the active sliding door mechanism 7 drives the door panel 21 to slide towards the first hinge 4, thereby preventing the closed door panel 21 from interfering with obstacles.

[0066] Meanwhile, the first driven sliding door mechanism 8 and the active sliding door mechanism 7 are coaxially arranged. The first driven sliding door mechanism 8 assists the door panel 21 in sliding relative to the cabinet door 2 under the drive of the active sliding door mechanism 7, and works with the active sliding door mechanism 7 to restrict the movement direction of the door panel 21, preventing the door panel 21 from swaying during movement, making the sliding of the door panel 21 more stable and smooth. The coaxial arrangement of the first driven sliding door mechanism 8 and the active sliding door mechanism 7 means that they share the same center line or axis, which helps to ensure that the door panel 21 can maintain stable linear movement during sliding, reducing the possibility of deviation or swaying. The coaxial arrangement is used in situations where precise control of the movement direction or maintenance of the relative positional relationship between components is required.

[0067] According to the door assembly of this application embodiment, the door 2 is rotatably connected to the box body 1, and the door panel 21 is slidably disposed on the outside of the door 2. An active sliding door mechanism 7 is provided on the door 2. The active sliding door mechanism 7 is connected to the door 2 and the door panel 21 respectively. During the process of the door 2 rotating open or close relative to the box body 1, the box body 1 drives the active sliding door mechanism 7 through a traction mechanism, so that the active sliding door mechanism 7 drives the door panel 21 to slide in the width direction relative to the door 2. This allows the door panel 21 to avoid obstacles such as side walls and objects during the closing or opening of the door 2, so as to meet the user's usage needs in different scenarios. At the same time, by setting a first driven sliding door mechanism 8 to support and assist the sliding of the door panel 21, the sliding of the door panel 21 is more stable and smooth, and the usage effect is better.

[0068] Optionally, in one embodiment of this application, as shown in Figures 1 and 2, both the first driven sliding door mechanism 8 and the active sliding door mechanism 7 are arranged along the width direction of the door 2, and the active sliding door mechanism 7 and the first driven sliding door mechanism 8 are arranged at the top or bottom of the door 2.

[0069] In this embodiment, both the active sliding door mechanism 7 and the first driven sliding door mechanism 8 are arranged along the width direction of the door 2, so as to drive or guide the door panel 21 to slide along the width direction of the door 2, allowing the door panel 21 to slide during the rotation of the door 2 to avoid obstacles on both sides. At the same time, the positions of the active sliding door mechanism 7 and the first driven sliding door mechanism 8 can be adjusted according to the layout requirements of the door 2.

[0070] Optionally, in one embodiment of this application, as shown in Figures 1 and 2, the door assembly further includes: a second driven sliding door mechanism 9, which is arranged along the width direction of the door 2 and is arranged on the door 2 off-axis from the active sliding door mechanism 7; the first driven sliding door mechanism 8 and the second driven sliding door mechanism 9 are configured to cooperate in guiding the door panel 21 to move relative to the door 2 during the opening or closing of the door 2.

[0071] In this embodiment, the second driven sliding door mechanism 9 and the active sliding door mechanism 7 are arranged on opposite axes, providing support and assistance for the sliding of the door panel 21 and preventing the door panel 21 from deflecting around the sliding direction during sliding. The first driven sliding door mechanism 8 and the second driven sliding door mechanism 9 can cooperate with the active sliding door mechanism 7 to make the sliding of the door panel 21 more stable and smooth.

[0072] The second driven sliding door mechanism 9 and the driving sliding door mechanism 7 are configured on opposite axes, meaning they do not share the same centerline or axis. This configuration is used to provide additional support, stability, or to prevent the door panel 21 from deflecting around the sliding direction during sliding. The opposite-axis configuration is used in situations requiring distributed force, increased stability, or the implementation of complex motion trajectories.

[0073] Optionally, in one embodiment of this application, as shown in Figures 1 and 2, the active sliding door mechanism 7 and the first driven sliding door mechanism 8 are disposed at the top of the cabinet door 2, and the second driven sliding door mechanism 9 is disposed at the bottom of the cabinet door 2.

[0074] In this embodiment, the active sliding door mechanism 7, the first driven sliding door mechanism 8, and the second driven sliding door mechanism 9 are all arranged along the width direction of the door 2, so as to drive or guide the door panel 21 to slide along the width direction of the door 2, allowing the door panel 21 to slide during the rotation of the door 2 to avoid obstacles on both sides. Simultaneously, by placing the active sliding door mechanism 7 and the first driven sliding door mechanism 8 at the top of the door 2, and the second driven sliding door mechanism 9 at the bottom of the door 2, the active sliding door mechanism 7, the first driven sliding door mechanism 8, and the second driven sliding door mechanism 9 can respectively limit the door panel 21 at the top and bottom of the door 2. While supporting the door panel 21, the door panel 21 swings and wobbles when closed. The structure is simple, convenient, and practical.

[0075] Optionally, in another embodiment of this application, the active sliding door mechanism 7 and the first driven sliding door mechanism 8 are disposed at the bottom of the cabinet door 2, and the second driven sliding door mechanism 9 is disposed at the top of the cabinet door 2.

[0076] Similar to the aforementioned embodiments, by setting the active sliding door mechanism 7 and the first driven sliding door mechanism 8 at the bottom of the cabinet door 2 and the second driven sliding door mechanism 9 at the top of the cabinet door 2, the door panel 21 can also be limited at the upper and lower ends of the cabinet door 2. While supporting the door panel 21, the door panel 21 swings and shakes when the door is closed. The structure is simple, convenient and practical.

[0077] In the embodiments of this application, as shown in Figures 2, 3, 4, and 5, the active sliding door mechanism 7 includes: a first base 717, a first slider 714, and a second slider 713. A first guide rail is formed on one side of the first base 717, and a second guide rail is formed on the other side. The first slider 714 is slidably mounted on the first guide rail and is connected to the housing 1 via a traction mechanism. The second slider 713 is slidably mounted on the second guide rail and connected to the door panel 21. The two ends of the connector 706 are respectively connected to the first slider 714 and the second slider 713. During the opening or closing of the housing door 2, the housing 1 drives the first slider 714 to move on the first guide rail via the traction mechanism, and the first slider 714 drives the second slider 713 to move in the opposite direction on the second guide rail via the connector 706, thereby driving the door panel 21 to move relative to the housing door 2.

[0078] It should be noted that, in practical applications, the design of the first slider 714, the second slider 713, and other sliders in this application 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.

[0079] From a materials perspective, the first slider 714, the second slider 713, and other sliders in this application 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. These material choices aim to improve the durability of the sliders, reduce wear and noise during sliding, and ensure smooth sliding.

[0080] In terms of structural design, the first slider 714, the second slider 713, and other sliders in this application 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.

[0081] The connector 706 can be a traction rope, transmission belt or other connecting component. The two ends of the connector 706 are connected to the first slider 714 and the second slider 713 respectively, so that the first slider 714 can drive the second slider 713 to move synchronously, thereby driving the door panel 21 to slide relative to the box door 2.

[0082] By reasonably setting the extension direction of the connector 706, the first slider 714 and the second slider 713 move in opposite directions during movement, thereby driving the door panel 21 to avoid obstacles.

[0083] Specifically, during the process of the door 2 rotating outwards to open the box body 1, the box body 1 drives the first slider 714 to slide towards the first hinge 4 via a traction mechanism. Simultaneously, the first slider 714, through the connector 706, drives the second slider 713 to slide in the opposite direction (i.e., away from the first hinge 4), thereby preventing interference between the door panel 21 and external obstacles. During the process of the door 2 rotating to close to one side of the box body 1, the box body 1 drives the first slider 714 to slide away from the first hinge 4 via a traction mechanism. Simultaneously, the first slider 714, through the connector 706, drives the second slider 713 to slide in the opposite direction (i.e., towards the first hinge 4), thereby preventing interference between the closed door panel 21 and obstacles.

[0084] In one embodiment of this application, as shown in Figures 4 to 6, the door assembly further includes a traction mechanism, which includes a traction rod 709, a first rotating shaft fixing seat 707, and a second rotating shaft fixing seat 710. The first rotating shaft fixing seat 707 is connected to the first slider 714, and the second rotating shaft fixing seat 710 is used to connect to the housing 1. One end of the traction rod 709 is rotatably connected to the first rotating shaft fixing seat 707, and the other end of the traction rod 709 is rotatably connected to the second rotating shaft fixing seat 710.

[0085] In this embodiment, by fixing the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710 to the first slider 714 and the box body 1 respectively, and connecting the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710 through a traction rod 709, the distance between the first slider 714 and the second rotating shaft fixing seat 710 remains constant. When the box door 2 rotates relative to the box body 1, the angle between the box body 1 and the box door 2 changes, thereby pulling the first slider 714 through the transmission connection of the traction rod 709, the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710, so that the first slider 714 slides on the first base 717, and drives the second slider 713 to slide, so as to realize the movement of the door panel 21 relative to the box door 2.

[0086] Specifically, one end of the traction rod 709 is rotatably connected to the first rotating shaft fixing seat 707 via a pin 708 and a third bearing 715, and the other end is rotatably connected to the second rotating shaft fixing seat 710 via another pin 708 and another third bearing 715.

[0087] In one embodiment of this application, as shown in Figures 3, 4 and 5, the connector 706 includes a first connector and a second connector. The first connector bypasses one end of the first base 717, and its two ends are respectively connected to one end of the first slider 714 and the second slider 713; the second connector bypasses the other end of the first base 717, and its two ends are respectively connected to the other ends of the first slider 714 and the second slider 713.

[0088] In this embodiment, by connecting the first connector, which bypasses one end of the first base 717, to the first slider 714 and the second slider 713 respectively, when the first slider 714 slides away from the first base 717 under the drive of the door 2, the first slider 714 drives the second slider 713 to slide closer to the first base 717 via the first connector; simultaneously, by connecting the second connector, which bypasses the other end of the first base 717, to the first slider 714 and the second slider 713 respectively, when the first slider 714 slides away from the first base 717, the first slider 714 drives the second slider 713 to slide closer to the first base 717. When the first slider 714 slides away from the first base 717 to the other end driven by the door 2, the second slider 713 is driven to slide towards the other end closer to the first base 717 through the second connector. This achieves that when the first slider 714 slides towards both ends of the first base 717, the second slider 713 can slide in the opposite direction to the first slider 714. This allows the door panel 21 to slide relative to the door 2 as the door 2 rotates when it is opened and closed, so as to avoid interference with obstacles and thus affect the opening and closing of the door 2.

[0089] Specifically, both the second slider 713 and the first slider 714 are provided with connectors 711 for fixing the connector 706.

[0090] In one embodiment of this application, as shown in Figures 3, 4 and 5, the active sliding door mechanism 7 further includes: a first fixed seat 701 and a second fixed seat 702. The first fixed seat 701 is connected to one end of the first base 717 and forms a first limiting groove. The two ends of the first limiting groove are connected to one end of the first guide rail and the second guide rail. A portion of the first connecting member is slidably disposed in the first limiting groove. The second fixed seat 702 is connected to the other end of the first base 717 and forms a second limiting groove. The two ends of the second limiting groove are connected to the other ends of the first guide rail and the second guide rail. A portion of the second connecting member is slidably disposed in the second limiting groove.

[0091] In this embodiment, by providing a first fixing seat 701 and a second fixing seat 702 at both ends of the first base 717, the first fixing seat 701 and the second fixing seat 702 are respectively formed with a first limiting groove and a second limiting groove that mate with the first guide rail and the second guide rail, respectively limiting and guiding the position of the first connector and the second connector, so that the sliding of the first connector and the second connector is smoother.

[0092] Specifically, in one embodiment of this application, the first fixed base 701 is provided with a first fixed hole, and the first base 717 is provided with a first waist-shaped hole extending along the width direction of the first base 717; the active sliding door mechanism 7 also includes a first adjusting member 704, which passes through the first fixed hole and is slidably disposed in the first waist-shaped hole, so as to adjust the tightness of the first connecting member and the second connecting member by adjusting the position of the first adjusting member 704 in the first waist-shaped hole.

[0093] In this embodiment, by adjusting the position of the first adjusting member 704 in the first waist-shaped hole, the position of the first fixing seat 701 can be adjusted along the width direction of the first base 717, so that the first fixing seat 701 can tighten or loosen the first connecting member, thereby adjusting the tightness of the first connecting member.

[0094] Since the first connector and the second connector are located on the first fixed seat 701 and the second fixed seat 702 on both sides of the first base 717, and the first connector and the second connector are connected to the two ends of the first slider 714 and the second slider 713, when the first fixed seat 701 is adjusted to move relative to the first base 717 through the first waist-shaped hole, the tightness of the first connector is adjusted accordingly, and the tightness of the second connector is also adjusted accordingly under the pull of the first fixed seat 701 on the first connector.

[0095] Understandably, the second fixed seat 702 may also be provided with a first fixed hole; the first base 717 is provided with a first waist-shaped hole extending along the width direction of the first base 717; the active sliding door mechanism 7 also includes a first adjusting member 704, which passes through the first fixed hole and is slidably disposed in the first waist-shaped hole, so as to adjust the tightness of the first connecting member and the second connecting member by adjusting the position of the first adjusting member 704 in the first waist-shaped hole.

[0096] In this embodiment, by adjusting the position of the first adjusting member 704 in the first waist-shaped hole, the position of the second fixing seat 702 can be adjusted along the width direction of the first base 717, so that the second fixing seat 702 can tighten or loosen the second connecting member, thereby adjusting the tightness of the second connecting member.

[0097] Since the first connector and the second connector are located on the first fixed seat 701 and the second fixed seat 702 on both sides of the first base 717, and the first connector and the second connector are connected to the two ends of the first slider 714 and the second slider 713, when the second fixed seat 702 is adjusted to move relative to the first base 717 through the first waist-shaped hole, the tightness of the second connector is adjusted accordingly, and the tightness of the first connector is also adjusted accordingly under the pull of the second fixed seat 702 on the second connector.

[0098] Furthermore, in some embodiments, the first fixed base 701 is provided with a second oblong hole extending along the width direction of the first base 717. The first base 717 is provided with a second fixing hole. The active sliding door mechanism 7 also includes a second adjusting member 703, which passes through the second oblong hole and the second fixing hole in sequence and is fixed in the external structure, so as to adjust the position of the first fixed base 701 relative to the external structure by the position of the second adjusting member 703 in the second oblong hole.

[0099] It is understood that the second fixing seat 702 may also be provided with a second oblong hole extending along the width direction of the first base 717; the second adjusting member 703 passes through the second oblong hole and the second fixing hole in sequence and is fixed in the external structure so as to adjust the position of the second fixing seat 702 relative to the external structure by the position of the second adjusting member 703 in the second oblong hole. The functions of the second adjusting member 703, the second oblong hole and the second fixing hole are similar to those in the above embodiment, and will not be described again here.

[0100] Furthermore, in some embodiments, a rotatable support bearing is provided in the first limiting groove; a portion of the first connector abuts against the support bearing in the first limiting groove. In this embodiment, by abutting a portion of the first connector against the support bearing, the movement of the first connector and its extension direction can be adjusted, facilitating the connection of the end of the first connector bypassing the first base 717 with the first slider 714 and the second slider 713.

[0101] It is understandable that a rotatable support bearing may also be provided in the second limiting groove; a portion of the second connecting member abuts against the support bearing in the second limiting groove in order to adjust the extension direction of the second connecting member, so as to facilitate connecting the end of the second connecting member that bypasses the first base 717 to the first slider 714 and the second slider 713.

[0102] Specifically, in some embodiments, the support bearing includes a first bearing 705 and a second bearing 716, which are located at one end of the first guide rail and the second guide rail on the same side, and on both sides of the first base 717.

[0103] In one embodiment of this application, as shown in Figures 2, 6 and 7, the first driven sliding door mechanism 8 includes a second base 817 and a third slider 813. A third guide rail is formed on the second base 817, and the third slider 813 is slidably disposed on the third guide rail. The third slider 813 is connected to the door panel 21.

[0104] In this embodiment, the first driven sliding door mechanism 8 and the active sliding door mechanism 7 are coaxially arranged. The third slider 813 can slide along the third guide rail and coaxially with the active sliding door mechanism 7, better assisting the door panel 21 to slide relative to the box door 2 under the drive of the active sliding door mechanism 7. At the same time, the third slider 813 can cooperate with the active sliding door mechanism 7 to restrict the movement direction of the door panel 21, preventing the door panel 21 from swinging during movement.

[0105] In one embodiment of this application, as shown in Figures 6 and 7, the first driven sliding door mechanism 8 can be configured with a similar structure to the active sliding door mechanism 7, and the first driven sliding door mechanism 8 can be interchanged when needed.

[0106] Furthermore, the first driven sliding door mechanism 8 also includes a third fixed seat 801 and a fourth fixed seat 802. The third fixed seat 801 and the fourth fixed seat 802 are also provided with limiting grooves similar to those of the first fixed seat 701 and the second fixed seat 702.

[0107] Specifically, the third fixing seat 801 is provided with a third fixing hole, and the second base 817 is provided with a third waist-shaped hole extending along the width direction of the second base 817; the third adjusting member 804 passes through the third fixing hole and is slidably disposed in the third waist-shaped hole so as to adjust the position of the third adjusting member 804 in the third waist-shaped hole.

[0108] Understandably, a third fixing hole can also be provided on the fourth fixing seat 802; a third oblong hole extending along the width direction of the second base 817 is provided on the second base 817; the third adjusting member 804 passes through the third fixing hole and is slidably disposed in the third oblong hole, so as to adjust the position of the third adjusting member 804 in the third oblong hole.

[0109] Furthermore, the third fixing base 801 is provided with a fourth oblong hole extending along the width direction of the second base 817. The second base 817 is provided with a fourth fixing hole. The fourth adjusting member 803 passes through the fourth oblong hole and the fourth fixing hole in sequence and is fixed in the external structure so as to adjust the position of the third fixing base 801 relative to the external structure by the position of the fourth adjusting member 803 in the fourth oblong hole.

[0110] Understandably, the fourth fixing seat 802 may also be provided with a fourth oblong hole extending along the width direction of the third base 902; the fourth adjusting member 803 passes through the fourth oblong hole and the fourth fixing hole in sequence and is fixed in the external structure so as to adjust the position of the fourth fixing seat 802 relative to the external structure by the position of the fourth adjusting member 803 in the fourth oblong hole.

[0111] In one embodiment of this application, as shown in Figures 2, 8 and 9, the second driven sliding door mechanism 9 includes a third base 902 and a fourth slider 903. A fourth guide rail is formed on the third base 902, and the fourth slider 903 is slidably disposed on the fourth guide rail. The fourth slider 903 is connected to the door panel 21, and the length of the fourth guide rail is greater than the length of the third guide rail.

[0112] In this embodiment, by providing a second driven sliding door mechanism 9, the fourth slider 903 of the second driven sliding door mechanism 9 can slide with the door panel 21 when the door panel 21 slides relative to the cabinet door 2, providing support and assistance for the sliding of the door panel 21, making the sliding of the door panel 21 relative to the cabinet door 2 more stable and smooth. At the same time, by making the length of the fourth guide rail greater than that of the third guide rail, when the door panel 21 slides relative to the cabinet door 2, the third slider 813 slides along the third guide rail, and the fourth slider 903 slides along the fourth guide rail. The longer length of the fourth guide rail makes it less likely for the fourth slider 903 to deviate from the track during the sliding process.

[0113] Meanwhile, the longer fourth guide rail allows for a longer fourth slider 903, resulting in a longer contact surface between the fourth slider 903 and the door panel 21, and a better supporting and assisting sliding effect of the second driven sliding door mechanism 9 on the door panel 21.

[0114] Understandably, as shown in Figures 8 and 9, the second driven sliding door mechanism 9 has a fifth fixed seat 901 and a sixth fixed seat 904 at both ends of the third base 902, which are used to fix and connect with the box door 2.

[0115] In one embodiment of this application, as shown in Figures 2, 6 to 9, the second slider 713, the third slider 813 and the fourth slider 903 are all provided with slots for the door panel 21 to be hung.

[0116] In this embodiment, slots are provided on the second slider 713, the third slider 813 and the fourth slider 903 to be attached to the door panel 21. This allows users to easily disassemble and replace the door panel 21 on the active sliding door mechanism 7 and the two driven sliding door mechanisms to meet different user scenarios.

[0117] Specifically, in one embodiment of this application, the second slider 713 is provided with a first connecting block 712, and the first connecting block 712 has a slot for the door panel 21 to be attached; the third slider 813 is provided with a second connecting block 812, and the second connecting block 812 has a slot for the door panel 21 to be attached; the fourth slider 903 is provided with a third connecting block 905, and the third connecting block 905 has a slot for the door panel 21 to be attached.

[0118] Accordingly, the door panel 21 is provided with connecting components (such as hooks, plugs, etc.) that are compatible with the slot.

[0119] In one embodiment of this application, as shown in Figures 10 and 11, a first hook 2111 is provided at the top of the door panel 21, and a second hook 2112 is provided at the bottom of the door panel 21. The length of the second hook 2112 is greater than the length of the first hook 2111. The first hook 2111 and the second hook 2112 are adapted to be inserted into corresponding slots.

[0120] In this embodiment, by providing a first hook 2111 and a second hook 2112 at the top and bottom of the door panel 21 respectively, the door panel 21 can be connected to the slots of the active sliding door mechanism 7 and the driven sliding door mechanism via the first hook 2111 and the second hook 2112, thereby slidably connecting the door panel 21 to the cabinet door 2. The first hook 2111 and the second hook 2112 are located at the top and bottom of the door panel 21 respectively, making the door panel 21 less prone to shaking.

[0121] In addition, the length of the second hook 2112 is greater than the length of the first hook 2111. When the door panel 21 is installed on the outside of the cabinet door 2, the slot at the bottom first engages with the second hook 2112 of the door panel 21 to initially position the bottom of the door panel 21. Then, the position and angle of the door panel 21 are adjusted so that the first hook 2111 at the top of the door panel 21 can be inserted into the slot at the top of the cabinet door 2. This makes it easier for the user to align the slot with the first hook 2111 and the second hook 2112, making installation more convenient.

[0122] Specifically, the first hook 2111 includes a connecting part and a hook part disposed on the connecting part. The hook part is hook-shaped and used to hook into the slot. The connecting part is provided with at least one waist-shaped hole extending in the horizontal direction and at least one waist-shaped hole extending in the vertical direction. The door panel 21 is provided with a fixing hole corresponding to the first hook 2111. The door panel 21 and the first hook 2111 are fixedly connected by a fixing member passing through the waist-shaped hole and the fixing hole. By adjusting the position of the fixing member in the waist-shaped hole, the position of the first hook 2111 can be finely adjusted, which facilitates the installation of the door panel 21 and the fine adjustment of the position and angle of the door panel 21.

[0123] Understandably, the second hook 2112 has a similar structure to the first hook 2111, and will not be described in detail here.

[0124] In one embodiment of this application, as shown in Figures 12 to 15, the door assembly further includes: a first end cover 210 and a second end cover 220. The first end cover 210 is disposed at one end of the door 2, and a first mounting groove 213 and a third mounting groove 212 are formed on the first end cover 210. A first driven sliding door mechanism 8 and an active sliding door mechanism 7 are respectively disposed in the third mounting groove 212 and the first mounting groove 213. The second end cover 220 is disposed at the other end of the door 2, and a second mounting groove is formed on the second end cover 220. A second driven sliding door mechanism 9 is disposed in the second mounting groove.

[0125] In this embodiment, by providing a first end cap 210 and a second end cap 220 at both ends of the door 2, and forming a first mounting groove 213 and a third mounting groove 212 on the first end cap 210 to install the active sliding door mechanism 7 and the first driven sliding door mechanism 8 respectively, and forming a second mounting groove on the second end cap 220 to install the second driven sliding door mechanism 9, the structure of the active sliding door mechanism 7, the two driven sliding door mechanisms, and the door 2 is made more compact and aesthetically pleasing.

[0126] In one embodiment of this application, as shown in Figures 2, 13, and 14, the first end cap 210 has first hinge holes 211 at both ends that are rotatably connected to the first hinge 4. The first end cap 210 can be connected to the first hinge 4 through the first hinge hole 211 at one end. The first end cap 210 is provided with a first mounting groove 213, and the groove wall of the first mounting groove 213 is provided with a first mounting hole 216. The active sliding door mechanism 7 is fixed by bolts through the first mounting hole 216 and the groove wall of the first mounting groove 213. The groove wall of the first mounting groove 213 facing the housing 1 has a first clearance opening 214 corresponding to the traction mechanism of the active sliding door mechanism 7. The traction mechanism of the active sliding door mechanism 7 is movably inserted into the first clearance opening 214 so as to move with the housing door 2 to pull the first slider 714.

[0127] The first end cap 210 is also provided with a third mounting groove 212, in which the first driven sliding door mechanism 8 is installed. It is understood that the positions of the active sliding door mechanism 7 and the first driven sliding door mechanism 8 can be interchanged according to the hinge position of the door 2 and the body 1. Correspondingly, a second clearance opening 215 is also provided on the groove wall of the third mounting groove 212 facing the body 1 to avoid the traction mechanism of the active sliding door mechanism 7.

[0128] Specifically, the opposite sides of the first mounting groove 213 and the third mounting groove 212 are provided with a third groove 218 and a fourth groove 219, as well as a first protruding ridge 217 for insertion, so as to be inserted and fixed with the first main decorative cover 13 or the first secondary decorative cover 17.

[0129] Specifically, as shown in Figures 18 and 19, the two end faces of the first main decorative cover 13 are respectively provided with a first notch 1303 and a third notch 1304 corresponding to the first mounting groove 213 and the third mounting groove 212, so that the first connecting block 712 and the second connecting block 812 of the active sliding door mechanism 7 and the first driven sliding door mechanism 8 can extend out of the notch and connect with the door panel 21. The two ends of the first main decorative cover 13 are provided with a fourth notch 1302 and a fifth notch 1301, so that the traction mechanism of the active sliding door mechanism 7 can swing with the movement of the door 2 when it is installed in the first mounting groove 213 or the third mounting groove 212. The first main decorative cover 13 is provided with a first slot 1305 corresponding to the first protrusion 217; the inner side of the first notch 1303 is provided with a first rib 1307 for engaging with the groove wall of the first mounting groove 213; the inner side of the third notch 1304 is provided with a second rib 1306 for engaging with the groove wall of the third mounting groove 212.

[0130] Correspondingly, the structure of the first secondary decorative cover 17 is similar to that of the first main decorative cover 13, but it does not have a notch for the first connecting block 712 and the second connecting block 812 to extend out, which will not be described in detail here.

[0131] The second end cover 220 has a third mounting hole 224 on the inner wall of the second mounting groove. The guide rail fixing seat 221 is installed in the second mounting groove through the third mounting hole 224. The guide rail fixing seat 221 has a second mounting hole 223. The second driven sliding door mechanism 9 is installed on the guide rail fixing seat 221 through the second mounting hole 223.

[0132] Specifically, the opposite sides of the second mounting groove are provided with a second protruding ridge 225 and a third protruding ridge 227 for insertion, so as to be inserted and fixed to the second main decorative cover 14 or the second auxiliary decorative cover 18.

[0133] Specifically, in one embodiment of this application, as shown in Figures 8, 9, 21, and 22, there are two third connecting blocks 905. Correspondingly, the second main decorative cover 14 has two second notches 1401 corresponding to the two third connecting blocks 905. A cavity for covering the second end cover 220 is formed inside the second main decorative cover 14. The two ends of the cavity are provided with a fourth protruding ridge 1403 and a fifth protruding ridge 1408, and the bottom of the cavity is provided with a sixth protruding ridge 1404 and a seventh protruding ridge 1407, so as to cooperate with the third protruding ridge 227 on the second end cover 220. At the same time, the bottom of the cavity is also provided with a second slot 1405 and a third slot 1406 that cooperate with the second protruding ridge 225 to assemble the second end cover 220 and the second main decorative cover 14 together.

[0134] Understandably, as shown in Figure 23, when the door panel 21 is not required to be installed, the second driven sliding door mechanism 9 in the second mounting groove can be removed. Correspondingly, the second decorative cover 18 is provided with a recessed handle 1801 at the position corresponding to the second mounting groove, so that the user can manually open and close the box door 2.

[0135] In another embodiment of this application, as shown in Figures 1 and 2, a refrigeration device is provided, including: a housing 1 and a door assembly as provided in any of the above embodiments. The housing 1 forms a storage space, and a door 2 is rotatably connected to the housing 1, adapted to open or close the storage space.

[0136] In this embodiment, the door assembly includes: a door 2, a door panel 21, an active sliding door mechanism 7, and a first driven sliding door mechanism 8. The active sliding door mechanism 7 is disposed on the door 2 and is configured to drive the door panel 21 to move relative to the width direction of the door 2 during the opening or closing of the door 2. The first driven sliding door mechanism 8 is configured to cooperate in guiding the door panel 21 to move relative to the door 2.

[0137] By setting a door panel 21 on the cabinet door 2, when the refrigeration equipment is embedded and set in a recessed space, or when it is set between two cabinets, the door panel 21 can be set flush with the cabinets on the side wall or sides of the recess, so as to reduce the gap between the refrigeration equipment and the adjacent wall or cabinet, making it more aesthetically pleasing.

[0138] Meanwhile, when the door 2 rotates, the active sliding door mechanism 7 can drive the door panel 21 to move relative to the door 2 during the rotation process, so as to move away from obstacles such as walls or cabinets on the side door of the cabinet 1 as much as possible, so as to avoid these obstacles blocking the door panel 21 and affecting the rotation of the door 2, causing the door 2 to be unable to open or close normally. The first driven sliding door mechanism 8 can support and assist the sliding of the door panel 21, making the sliding of the door panel 21 more stable and smooth, and less prone to shaking.

[0139] The combination of door 2 and door panel 21 ensures that the refrigeration equipment can avoid interference between the door panel 21 and surrounding objects when opening and closing, greatly improving ease of use. This design advantage is especially evident in confined kitchen environments. Furthermore, the active sliding door mechanism 7 and the first driven sliding door mechanism 8 enable the door panel 21 to move smoothly during opening and closing, improving the refrigerator's lifespan and stability.

[0140] 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.

[0141] As shown in Figure 1, an application scenario based on the above embodiment is as follows: A refrigeration device can be installed in a slotted structure in the middle of a cabinet. A door panel 21 is provided on the outer side of the cabinet door 2 of the refrigeration device's cabinet body 1. The material and color of the door panel 21 can be designed to be similar to or the same as the material and color of the outer wall of the cabinet. When the door 2 is closed, the door panel 21 is flush with the outer wall of the cabinet at the edge of the slotted structure opening, and fits as close as possible to the opening of the slotted structure, so that the door panel 21 and the outer wall of the cabinet maintain visual consistency with minimal gaps, resulting in a more aesthetically pleasing appearance.

[0142] When the cabinet door 2 is rotated outward to open, the active sliding door mechanism 7 drives the door panel 21 to slide away from the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall on the side closer to the first hinge 4, which would prevent the cabinet door 2 from opening to a larger angle. When the cabinet door 2 is rotated to close, the active sliding door mechanism 7 drives the door panel 21 to slide closer to the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall on the side away from the first hinge 4, which would prevent the cabinet door 2 from closing completely and affecting the refrigeration and preservation effect in the storage space. Furthermore, when the cabinet door 2 is fully closed, the door panel 21 can return to a state flush with the cabinet body.

[0143] Optionally, the enclosure 1 may have one or more storage spaces, each of which is equipped with a corresponding door assembly. It is understood that the multiple storage spaces can be arranged arbitrarily, such as vertically or horizontally.

[0144] Specifically, the cabinet 1 has at least two storage spaces, and multiple door components are provided, each door component corresponding to one of the storage spaces, so as to drive the door panel 21 to move relative to the door 2 during the opening or closing of any door 2.

[0145] In one embodiment of this application, as shown in Figures 1 and 2, the cabinet 1 has a first storage space and a second storage space. Accordingly, there are two door assemblies, namely a first door assembly and a second door assembly. The door 2 of the first door assembly is rotatably connected to the cabinet 1 to open or close the first storage space, and the door 2 of the second door assembly is rotatably connected to the cabinet 1 to open or close the second storage space.

[0146] In this embodiment, the first door assembly and the second door assembly are respectively disposed in the first storage space and the second storage space, so that when the user opens or closes the corresponding door 2 of the first storage space or the second storage space, the door panel 21 of the corresponding door 2 can move relative to the door 2 under the drive of the corresponding active sliding door mechanism 7 to avoid obstacles on the side of the door panel 21.

[0147] Furthermore, the first storage space and the second storage space are arranged sequentially along the height direction of the box 1.
