[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese patent application No. 202422089073.4, 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 proposes a door assembly and a refrigeration device to solve the problem that a 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.

[0007] A door assembly according to an embodiment of this application is applied to a refrigeration device, the refrigeration device including a housing;

[0008] The door assembly includes: an active sliding door mechanism, a first driven sliding door mechanism, a cabinet door, and a door panel; the cabinet door is rotatably connected to the cabinet body, and the cabinet door is adapted to open or close the storage space of the cabinet body; the door panel is slidably disposed on the outside of the cabinet door;

[0009] The top left and right sides of the top of the box door are respectively provided with a first mounting groove and a second mounting groove.

The active sliding door mechanism is connected to the box body in a transmission manner.

[0010] The first driven sliding door mechanism is disposed on the box door and is connected to the driving sliding door mechanism in a transmission manner; the first driven sliding door mechanism is connected to the door panel.

[0011] During the opening or closing of the cabinet door, the cabinet body drives the active sliding door mechanism, which in turn drives the first driven sliding door mechanism to move the door panel relative to the width direction of the cabinet door.

[0012] In one embodiment, the door assembly further includes: a first hinge and a second hinge; the first hinge is detachably connected to the left side of the housing and the door, and the second hinge is detachably connected to the right side of the housing and the door.

[0013] When the active sliding door mechanism is located in the first mounting slot, the box door is rotatably connected to the left side of the box body via the first hinge;

[0014] When the active sliding door mechanism is located in the second mounting slot, the door is rotatably connected to the right side of the box body via the second hinge.

[0015] In this embodiment, the active sliding door mechanism includes:

[0019] The second slider is slidably mounted on the second guide rail and is connected to the first driven sliding door mechanism in a transmission manner;

[0020] The flexible rope has its two ends connected to the first slider and the second slider, respectively.

[0021] When the housing drives the first slider to move on the first guide rail via the traction component, the first slider drives the second slider to move in the opposite direction on the second guide rail via the flexible cable.

[0022] In one embodiment, the flexible cord includes:

[0023] A first flexible cable passes around one end of the first base, and its two ends are respectively connected to one end of the first slider and one end of the second slider;

[0024] The second flexible cable passes around the other end of the first base, and its two ends are respectively connected to the other ends of the first slider and the second slider.

[0025] In this embodiment, the first driven sliding door mechanism includes:

[0026] The second base is connected to the second slider on the inner side and to the door panel on the outer side, and a third guide rail is formed inside the second base;

[0027] The third slider is slidably disposed in the third guide rail and connected to the box door;

[0028] When the second slider moves on the second guide rail, the second slider drives the second base to move relative to the third slider in the third guide rail.

[0029] In this embodiment, the first driven sliding door mechanism further includes:

[0030] A support frame is disposed between the third slider and the third guide rail, forming a limit notch;

[0031] A ball bearing is rotatably disposed in the limiting notch, with one side of the ball bearing abutting against the third guide rail and the other side of the ball bearing passing through the limiting notch and abutting against the third slider.

[0032] In one embodiment, the third guide rail is provided with limiting members, which are located on both sides of the third slider; when the third slider moves within the third guide rail, the movement range of the third slider is limited by the contact between the limiting members and the third slider.

[0033] In this embodiment, the first driven sliding door mechanism further includes:

[0034] The first bracket is connected to the outside of the second base and is used to hang the door panel.

[0035] In this embodiment, the active sliding door mechanism and the first driven sliding door mechanism are disposed at the top of the door. The door assembly further includes a second driven sliding door mechanism disposed at the bottom of the door and connected to the door panel. During the opening or closing of the door, the second driven sliding door mechanism cooperates with the first driven sliding door mechanism to guide the door panel to move relative to the width direction of the door.

[0036] In this embodiment, the second driven sliding door mechanism includes:

[0037] A third base, wherein a fourth guide rail is formed within the third base;

[0038] The fourth slider is slidably disposed in the fourth guide rail and connected to the box door;

[0040] The refrigeration device according to an embodiment of this application includes:

[0041] The box-shaped structure forms a storage space;

[0042] The aforementioned door assembly includes a door that is rotatably connected to the cabinet body, suitable for opening or closing the storage space.

[0043] The above-described one or more technical solutions in the embodiments of this application have at least one of the following technical effects:

[0044] According to the door assembly of this application, there are an active sliding door mechanism, a first driven sliding door mechanism, a cabinet door, and a door panel. This door assembly is suitable for cabinet doors that rotate on the left or right. The active sliding door mechanism can be selectively installed in either a first or second mounting slot as needed, and is connected to the first driven sliding door mechanism via a transmission connection. The first driven sliding door mechanism is connected to the door panel, allowing the cabinet to drive the first driven sliding door mechanism via the active sliding door mechanism. The first driven sliding door mechanism then drives the door panel to move relative to the width of the cabinet door, allowing the door panel to avoid obstacles on both sides and solving the interference problem during opening. Simultaneously, the active sliding door mechanism, which directly bears the driving force, does not bear the weight of the door panel, while the first driven sliding door mechanism, connected to the door panel, bears the weight of the entire door panel. This prevents the active sliding door mechanism from being subjected to external forces in other directions during the opening or closing of the cabinet door, reducing the problem of the door panel swaying relative to the cabinet door.

[0045] According to the embodiments of this application, the refrigeration device, by combining the cabinet door and the door panel, avoids interference between the door panel and surrounding objects when opening and closing the refrigeration device, greatly improving ease of use. This design advantage is particularly evident in confined kitchen environments.

[0064] The door assembly and refrigeration device of this application are described below with reference to Figures 1 to 10. The door assembly of this application can be applied to the door 2 or cabinet door of a household appliance, such as the door 2 of a refrigerator; however, it should be understood that the door assembly of this application can also be applied to any other suitable device. 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.

[0065] In one embodiment of this application, as shown in Figures 1 and 2, the door assembly is applied to a refrigeration device. The refrigeration device includes a cabinet 4. The door assembly includes an active sliding door mechanism 1, a first driven sliding door mechanism 9, a cabinet door 2, and a door panel 3. The cabinet door 2 is rotatably connected to the cabinet 4. The cabinet door 2 is adapted to open or close the storage space of the cabinet 4. The door panel 3 is slidably disposed on the outside of the cabinet door 2.

[0066] In this embodiment, a first mounting groove 21 and a second mounting groove 22 are respectively provided on the left and right sides of the top of the box door 2. The active sliding door mechanism 1 is selectively provided in the first mounting groove 21 or the second mounting groove 22 to use the left hinged box door 2 or the right hinged box door 2. The active sliding door mechanism 1 is connected to the box body 4 in a transmission manner. The first driven sliding door mechanism 9 is provided on the box door 2 and is connected to the active sliding door mechanism 1 in a transmission manner. The first driven sliding door mechanism 9 is connected to the door panel 3. During the opening or closing of the box door 2, the box body 4 drives the active sliding door mechanism 1, and the active sliding door mechanism 1 drives the first driven sliding door mechanism 9, so that the door panel 3 is moved relative to the width direction of the box door 2 through the first driven sliding door mechanism 9.

[0067] In this embodiment, the cabinet 4 serves as the main body of the refrigeration equipment. The cabinet 4 contains a storage space for storing food or other items requiring refrigeration or freezing. The cabinet door 2 is hinged to the cabinet 4 on either the left or right side, as needed. It can rotate around one or more axes to open and close the storage space. The door panel 3, as an additional, sliding component, is located on the outside of the cabinet door 2.

[0068] In this embodiment, when the door 2 is opened or closed, the cabinet 4 transmits power to the first driven sliding door mechanism 9 through the movement of the active sliding door mechanism 1. The active sliding door mechanism 1 does not directly bear the weight of the door panel 3, but rather serves as the key to transmitting power, converting the power of the cabinet 4 into driving the first driven sliding door mechanism 9. The first driven sliding door mechanism 9 works closely with the active sliding door mechanism 1, directly connecting to and driving the door panel 3 to move.

[0069] Specifically, during the opening or closing of the door 2, the cabinet 4 drives the active sliding door mechanism 1. The active sliding door mechanism 1 drives the first driven sliding door mechanism 9, which in turn drives the door panel 3 to move relative to the width of the door 2, thereby preventing the door panel 3 from interfering with external obstacles. In this process, the active sliding door mechanism 1, which directly bears the driving force, does not bear the weight of the door panel 3, while the first driven sliding door mechanism 9, which is connected to the door panel 3, bears the weight of the entire door panel 3. This prevents the active sliding door mechanism 1 from being subjected to external forces in other directions during the opening or closing of the door 2, reducing the problem of the door panel 3 swaying when moving relative to the door 2.

[0070] According to the embodiment, the door assembly includes an active sliding door mechanism, a first driven sliding door mechanism, a cabinet door, and a door panel. This door assembly is suitable for cabinet doors that rotate on the left or right. The active sliding door mechanism can be selectively positioned in either a first or second mounting slot, and is connected to the first driven sliding door mechanism via a transmission connection. The first driven sliding door mechanism is connected to the door panel, allowing the cabinet to drive the first driven sliding door mechanism via the active sliding door mechanism. The first driven sliding door mechanism then drives the door panel to move relative to the width of the cabinet door, allowing the door panel to avoid obstacles on either side and resolving interference issues during opening. Simultaneously, the active sliding door mechanism, which directly bears the driving force, does not bear the weight of the door panel, while the first driven sliding door mechanism, connected to the door panel, bears the entire weight of the door panel. This prevents the active sliding door mechanism from being subjected to external forces in other directions during the opening or closing of the cabinet door, reducing the problem of the door panel swaying relative to the cabinet door.

[0071] In some embodiments, as shown in Figures 1 to 4, the door assembly further includes: a first hinge 51 and a second hinge 52; the first hinge 51 is detachably connected to the left side of the housing 4 and the door 2, and the second hinge 52 is detachably connected to the right side of the housing 4 and the door 2; when the active sliding door mechanism 1 is provided in the first mounting groove 21, the door 2 is rotatably connected to the left side of the housing 4 via the first hinge 51; when the active sliding door mechanism 1 is provided in the second mounting groove 22, the door 2 is rotatably connected to the right side of the housing 4 via the second hinge 52.

[0072] In this embodiment, both the first hinge 51 and the second hinge 52 are detachably connected between the housing 4 and the door 2. The corresponding active sliding door mechanism 1 is selectively located in either the first mounting slot 21 on the left or the second mounting slot 22 on the right. When the active sliding door mechanism 1 is located in the first mounting slot 21, the door 2 is rotatably connected to the left side of the housing 4 via the first hinge 51, as shown in Figure 2; in this case, the door 2 opens to the right. Similarly, when the active sliding door mechanism 1 is located in the second mounting slot 22, the door 2 is rotatably connected to the right side of the housing 4 via the second hinge 52, as shown in Figure 1; in this case, the door 2 opens to the left. This design allows the door 2 to open in different ways to meet different usage scenarios and needs.

[0073] In this way, users can easily install or remove the hinges as needed, thereby changing the way the door 2 opens.

[0074] In some embodiments, as shown in FIG5, the active sliding door mechanism 1 includes: a traction component 17, a first base 13, a first slider 11, a second slider 12, and a flexible cable 14. A first guide rail 131 is formed on one side of the first base 13, and a second guide rail 132 is formed on the other side. One end of the traction component 17 is connected to the housing 4, and the other end is connected to the first slider 11. The first slider 11 is slidably disposed on the first guide rail 131 and connected to the housing 4 via the traction component 17; the second slider 12 is slidably disposed on the second guide rail 132 and is drivenly connected to the first driven sliding door mechanism 9; both ends of the flexible cable 14 are connected to the first slider 11 and the second slider 12, respectively. When the housing 4 drives the first slider 11 to move on the first guide rail 131 via the traction component 17, the first slider 11 drives the second slider 12 to move in the opposite direction on the second guide rail 132 via the flexible cable 14.

[0075] In this embodiment, the first base 13 is fixed to the door 2, and a first guide rail 131 and a second guide rail 132 are formed on its inner and outer sides, respectively. The first guide rail 131 and the second guide rail 132 provide tracks for the sliding of the first slider 11 and the second slider 12, respectively. The first slider 11 is slidably fitted on the first guide rail 131 and is connected to the housing 4 through the traction component 17, and is driven by the housing 4 to move on the first guide rail 131. The second slider 12 is also slidably fitted on the second guide rail 132, but is connected to the first driven sliding door mechanism 9 to drive the first driven sliding door mechanism 9. The flexible cable 14 can be a traction rope, transmission belt, or other connecting component. The two ends of the flexible cable 14 are connected to the first slider 11 and the second slider 12, respectively, so that the first slider 11 can drive the second slider 12 to move synchronously, so that the two move in opposite directions. This design ensures that during the sliding of the door panel 3 along the width direction of the box body 4, the first slider 11 and the second slider 12 only bear the driving force of the traction component 17, and do not need to bear the weight of the door panel 3 in the vertical direction. The weight of the entire door panel 3 is only supported by the first driven sliding door mechanism 9, which reduces the problem of the door panel 3 shaking when moving relative to the box door 2.

[0076] During the process of the door 2 rotating outwards to open the box body 4, the box body 4 drives the first slider 11 to slide towards the hinge 5 via the traction component 17. Simultaneously, the first slider 11 drives the second slider 12 to slide in the opposite direction via the flexible cable 14. The second slider 12 drives the first driven sliding door mechanism 9, which in turn drives the door panel 3 to move, thus preventing the door panel 3 from interfering with external obstacles. During the process of the door 2 rotating outwards to close the box body 4, the box body 4 drives the first slider 11 to slide away from the hinge 5 via the traction component 17. Simultaneously, the first slider 11 drives the second slider 12 to slide in the opposite direction via the flexible cable 14. The second slider 12 drives the first driven sliding door mechanism 9, which in turn drives the door panel 3 to move, preventing the closed door panel 3 from interfering with obstacles.

[0077] In some embodiments, as shown in FIG5, the flexible cable 14 includes a first flexible cable and a second flexible cable. The first flexible cable 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 flexible cable 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.

[0078] In this embodiment, by connecting the first flexible cable around one end of the first base 13 to the first slider 11 and the second slider 12 respectively, when the first slider 11 slides away from the first base 13 under the drive of the housing 4, the first slider 11 drives the second slider 12 to slide towards the end closer to the first base 13 via the first flexible cable. At the same time, by connecting the second flexible cable around the other end of the first base 13 to the first slider 11 and the second slider 12 respectively, when the first slider 11 slides away from the first base 13 under the drive of the door 2, the first slider 11 drives the second slider 12 to slide towards the other end closer to the first base 13 via the second flexible cable. This achieves that when the first slider 11 slides towards both ends of the first base 13, it can drive the second slider 12 to slide in the opposite direction to the first slider 11. This, in conjunction with the first driven sliding door mechanism 9, enables the door panel 3 to slide relative to the door 2 as the door 2 rotates during opening and closing, thus avoiding interference with obstacles and affecting the opening and closing of the door 2.

[0079] In some embodiments, as shown in FIG5, the active sliding door mechanism 1 further includes a first fixed seat 15 and a second fixed seat 16. The first fixed seat 15 is connected to one end of the first base 13 and forms a first limiting groove. The two ends of the first limiting groove are connected to one end of the first guide rail 131 and the second guide rail 132. A portion of the first flexible cable is slidably disposed in the first limiting groove. The second fixed seat 16 is connected to the other end of the first base 13 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 131 and the second guide rail 132. A portion of the second flexible cable is slidably disposed in the second limiting groove.

[0080] Specifically, the first fixed seat 15 is connected to one end of the first base 13, serving as an extension and support for the first guide rail 131 and the second guide rail 132 at that end. A first limiting groove is formed on the first fixed seat 15, which not only provides an additional sliding track for the first flexible cable but also ensures the stability and accuracy of the first flexible cable during sliding. The two ends of the first limiting groove are connected to one end of the first guide rail 131 and the second guide rail 132. The presence of the first limiting groove restricts the offset and swaying of the first flexible cable during sliding, improving the operating accuracy and reliability of the entire active sliding door mechanism 1. The second fixed seat 16 corresponds to the first fixed seat 15, and is connected to the other end of the first base 13, providing support and extension for the first guide rail 131 and the second guide rail 132 at that end. A second limiting groove is formed on the second fixed seat 16, with a design similar to the first limiting groove, but located at the other end of the active sliding door mechanism 1. The two ends of the second limiting groove are connected to the other ends of the first guide rail 131 and the second guide rail 132, providing guidance and limiting for the sliding of the second flexible cable. The second limiting groove is the same as the first limiting groove, and the second limiting groove also plays the role of limiting the offset and sway of the flexible cable 14.

[0081] In order to install the active sliding mechanism, in some embodiments, as shown in FIG5, the first fixed seat 15 and / or the second fixed seat 16 are provided with fixing holes. The active sliding door mechanism 1 also includes a fixing member, which passes through the fixing hole to connect with the box door 2, thereby enabling the entire active sliding door mechanism 1 to be fixed on the box door 2.

[0082] In this embodiment, the first fixed seat 15 and / or the second fixed seat 16, which are connected to the first base 13, are fixed to the door 2 by fasteners, ensuring that the mechanism will not loosen or shift due to external forces or vibrations during operation. The design of the fixing holes and fasteners makes the installation process simple and quick. The operator only needs to align the fasteners with the fixing holes and tighten them to complete the connection between the active sliding door mechanism 1 and the door 2. When it is necessary to repair or replace the active sliding door mechanism 1, the active sliding door mechanism 1 can be removed from the door 2 simply by removing the fasteners, without the need for complicated disassembly work. This greatly improves the maintainability and flexibility of the equipment.

[0083] In practical implementation, appropriate fasteners, such as screws, bolts, and rivets, can be selected based on the structure and material of the door 2. Simultaneously, it is necessary to ensure that the position and size of the fixing holes match the fasteners to guarantee the strength and stability of the connection.

[0084] In some embodiments, as shown in Figures 5, 6, and 7, the first driven sliding door mechanism 9 includes a second base 91 and a third slider 92. The inner side of the second base 91 is connected to the second slider 12 via a fixing plate 95, and the outer side is connected to the door panel 3. A third guide rail 911 is formed inside the second base 91. The third slider 92 is slidably disposed in the third guide rail 911 and is connected to the door 2. When the second slider 12 moves on the second guide rail 132, the second slider 12 drives the second base 91 to move relative to the third slider 92 through the third guide rail 911.

[0085] In this embodiment, the inner side of the second base 91 is connected to the second slider 12, and the second base 91 moves along with the second slider 12 on the second guide rail 132. Simultaneously, its outer side is directly connected to the door panel 3, so that when the second base 91 moves, it can move the door panel 3 along with it. The second base 91 has a third guide rail 911 inside, used to accommodate and guide the sliding of the third slider 92. The third slider 92 not only interacts with the third guide rail 911 to achieve the sliding function, but it is also connected to the door 2 (or possibly part of the door). This means that when the third slider 92 moves in the third guide rail 911, the relative movement of the second base 91 and the third slider 92 enables the door panel 3 to move relative to the door 2.

[0086] When the second slider 12 moves along the second guide rail 132, the second base 91 will also move because its inner side is connected to the second slider 12. During this process, since the third slider 92 is fixed to the door 2 and slidably disposed in the third guide rail 911 of the second base 91, when the second base 91 moves, it will drive the door panel 3 to move accordingly through the relative movement of the third guide rail 911 and the third slider 92.

[0087] In some embodiments, as shown in Figures 5 to 7, the first driven sliding door mechanism 9 further includes a first ball bearing support 93. The first ball bearing support 93 is slidably connected to the third guide rail 911, and the third slider 92 is slidably connected to the first ball bearing support 93. When the second slider 12 moves on the second guide rail 132, it drives the second base 91 to move via a connecting member (such as a rod, chain, etc.) or by direct action. As the second base 91 moves, the third slider 92 moves relative to it. At this time, with the assistance of the first ball bearing support 93, the third slider 92 slides with low friction and high efficiency on the third guide rail 911. Due to the presence of the first ball bearing support 93, the sliding process of the third slider 92 becomes smoother and more reliable, thereby ensuring the stable operation of the entire first driven sliding door mechanism 9.

[0088] Specifically, the first ball support 93 includes a support frame and a ball (not shown). The support frame is disposed between the third guide rail 911 and the third slider 92, and a limiting notch is formed on the support frame; the ball is rotatably disposed in the limiting notch, with one side of the ball abutting against the third guide rail 911 and the other side of the ball passing through the limiting notch and abutting against the third slider 92.

[0089] In this embodiment, a support frame is disposed between the third guide rail 911 and the third slider 92. It ensures that the balls roll in the correct position, thereby supporting the sliding of the third slider 92. A limiting notch is designed on the support frame to accommodate the balls and limit their rolling range. The limiting notch ensures that the balls do not detach from the support frame during rolling, while also providing a certain rolling space for the balls. The balls are rotatably disposed in the limiting notch, with one side abutting against the third guide rail 911 and the other side passing through the limiting notch abutting against the third slider 92. This design means that when the third slider 92 slides, it no longer directly contacts the third guide rail 911 and generates sliding friction, but rather achieves sliding through the rolling of the balls. This method greatly reduces frictional resistance during sliding and improves sliding efficiency. Since the rolling of the balls is low-friction, it can significantly reduce wear between the third slider 92 and the third guide rail 911. This helps extend the service life of these two components and reduce maintenance costs.

[0090] When the third slider 92 needs to slide along the third guide rail 911, the second base 91 is subjected to an external driving force (such as the driving force from the second slider 12). During this process, the second base 91 pushes the ball to roll within the limiting notch of the support frame. One side of the ball remains in contact with and rolls along the third guide rail 911, while the other side remains in contact with and rolls along the third slider 92. In this way, the first ball support 93 provides stable and efficient support for the sliding of the third slider 92.

[0091] In summary, the first ball bearing support 93 in this embodiment, through the combination design of the support frame and the ball bearing, effectively supports and assists the sliding of the third slider 92 in the third guide rail 911, thereby effectively improving the sliding efficiency.

[0092] Furthermore, as shown in Figures 6 and 7, the third guide rail 911 is provided with limiting members 912, which are located on both sides of the third slider 92. When the third slider 92 moves within the third guide rail 911, the movement range of the third slider 92 is limited by the contact between the limiting members 912 and the third slider 92. The limiting members 912 should be precisely installed at appropriate positions on the third guide rail 911 to ensure that they can effectively limit the movement range of the third slider 92. Generally, the position of the limiting members 912 is determined according to the movement requirements of the door panel 3 and the cabinet door 2. The shape and size of the limiting members 912 should be determined according to the contour and movement of the third slider 92 to withstand the impact force generated by the third slider 92 upon contact and maintain a stable limiting effect.

[0093] During operation, as the third slider 92 moves within the third guide rail 911, the second base 91 slides under the influence of an external driving force (such as the driving force from the second slider 12). During this process, if the relative position of the third slider 92 and the second base 91 attempts to exceed a predetermined range of movement, the third slider 92 will contact the limiting member 912 on either side. Once contact occurs, the limiting member 912 will prevent the third slider 92 from continuing to move relative to the second base 91, thereby confining it within the predetermined range.

[0094] In one example, as shown in Figures 1 to 6, to facilitate the installation of the door panel 3, the first driven sliding door mechanism 9 further includes a first bracket 94. The first bracket 94 is connected to the outside of the second base 91 and is used to hang the door panel 3.

[0095] In this embodiment, the first bracket 94 serves as the mounting point for the door panel 3, making the installation of the door panel 3 simpler and faster. Installers only need to hang the door panel 3 onto the first bracket 94 without requiring complex fixing or connection operations. The first bracket 94 has a connection structure that matches the outer side of the second base 91 to ensure a secure connection. This connection structure can be a bolted connection, welding, or other reliable connection method. Simultaneously, the first bracket 94 has mounting points suitable for hanging the door panel 3 to withstand the weight of the door panel 3 and the forces generated during sliding.

[0096] During installation, the installers first securely connect the first bracket 94 to the outside of the second base 91. Then, they hang or connect the corresponding part of the door panel 3 to the first bracket 94. Because the connection between the first bracket 94 and the second base 91 is secure, the door panel 3 also maintains a stable connection with the second base 91 through the first bracket 94.

[0097] In one embodiment of this application, a door assembly is provided, as shown in Figures 1 to 4. A first driven sliding door mechanism 1 is disposed at the top of the door 2. The door assembly further includes a second driven sliding door mechanism 18, which is disposed at the bottom of the door 2. The second driven sliding door mechanism 18 is connected to the door panel 3. During the opening or closing of the door 2, the second driven sliding door mechanism 18 cooperates with the first driven sliding door mechanism 9 to guide the door panel 3 to move relative to the width direction of the door 2.

[0098] Specifically, in this embodiment, the traction component 17, the active sliding door mechanism 1, and the first driven sliding door mechanism 9 are disposed at the top of the door 2. The second driven sliding door mechanism 18 is disposed at the bottom of the door 2. During the opening or closing of the door 2, the box body 4 drives the active sliding door mechanism 1 through the traction component 17. The active sliding door mechanism 1 drives the first driven sliding door mechanism 9, thereby driving the door panel 3 to move relative to the width direction of the door 2, thus avoiding interference between the door panel 3 and external obstacles. During this process, the second driven sliding door mechanism 18 cooperates with the first driven sliding door mechanism 9 to guide the door panel 3 to move relative to the width direction of the door 2, which can effectively improve the stability during movement.

[0099] In this embodiment, the coordinated operation of the active sliding door mechanism 1, the first driven sliding door mechanism 9, and the second driven sliding door mechanism 18 effectively restricts the movement direction of the door panel 3. This ensures that the door panel 3 moves along a predetermined trajectory during sliding, avoiding wobbling and instability caused by directional deviation. This restrictive effect ensures the stability of the door panel 3.

[0100] In one embodiment, as shown in FIG8, the second driven sliding door mechanism 18 is a C-shaped drawer track structure, including: a third base 181, a fourth slider 182, and a second hanger 183. A fourth guide rail 1811 is formed inside the third base 181. The fourth slider 182 is slidably disposed (generally internally connected to) the fourth guide rail 1811 and is connected to the cabinet door 2; the second hanger 183 is connected to the outside of the third base 181 and is used to hang the door panel 3.

[0101] In this embodiment, the third base 181 has a fourth guide rail 1811 on its inner side and a fourth slider 182 connected to the door 2. The outer side of the third base 181 is connected to the door panel 3 through the second bracket 183. When the door panel 3 moves relative to the door 2, the third base 181 moves relative to the fourth slider 182 through the fourth guide rail 1811, thereby cooperating to guide the movement of the door panel 3 and the door 2.

[0102] Similarly, the second driven sliding door mechanism 18 also includes a second ball bearing support 184. The second ball bearing support 184 is slidably connected to the fourth guide rail 1811, and the fourth slider 182 is slidably connected to the second ball bearing support 184. With the assistance of the second ball bearing support 184, the fourth slider 182 slides along the fourth guide rail 1811 with low friction and high efficiency. Due to the presence of the second ball bearing support 184, the sliding process of the fourth slider 182 becomes smoother and more reliable, thus ensuring the stable operation of the entire second driven sliding door mechanism 18. It should be noted that the specific structure of the second ball bearing support 184 is the same as that of the first ball bearing support 93, and will not be described again here.

[0103] It should be noted that in practical applications, the design of the first slider 11, the second slider 12, the third slider 92, and the fourth slider 182 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.

[0104] From a materials perspective, the first slider 11, the second slider 12, the third slider 92, and the fourth slider 182 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.

[0105] In terms of structural design, the first slider 11, the second slider 12, the third slider 92, and the fourth slider 182 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.

[0106] In another embodiment of this application, as shown in Figures 1 to 10, 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 structure of the door assembly can be found in the above embodiments and will not be repeated here.

[0107] By installing a door panel 3 on the cabinet door 2, when the refrigeration equipment is embedded and installed 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, thereby reducing the gap between the refrigeration equipment and the adjacent wall or cabinet, making it more aesthetically pleasing.

[0108] Meanwhile, when the door 2 rotates, the active sliding door mechanism 1 can drive the door panel 3 to move relative to the door 2 during the rotation process, so as to move away from the wall or cabinet of the side door of the cabinet 4 as much as possible, so as to avoid these obstacles blocking the door panel 3 and affecting the rotation of the door 2, causing the door 2 to be unable to open or close normally.

[0109] The combination of door 2 and door panel 3 prevents interference between door panel 3 and surrounding objects when the refrigeration equipment is opened and closed, greatly improving ease of use. This design advantage is especially evident in confined kitchen environments. Furthermore, the slider and guide rails within the active sliding door mechanism 1 allow door panel 3 to move smoothly and seamlessly during opening and closing, improving the refrigerator's lifespan and stability.

[0110] 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.

[0111] In some embodiments, as shown in Figures 9 and 10, the door assembly and the cabinet 4 are disposed within an installation space 8 formed between the first cabinet 6 and the second cabinet 7. An opening is provided on the outer side of the installation space 8, allowing the door assembly and the cabinet 4 to be integrally embedded into the cabinet. During the opening or closing of the storage space by the cabinet door 2 passing through the opening, the active sliding door mechanism 1 is configured to drive the door panel 3 to move a predetermined distance away from or towards the hinge 5 on the cabinet door 2, so that the door panel 3 avoids the side walls of the first cabinet 6 and the second cabinet 7.

[0112] During the opening or closing of the storage space controlled by the opening through the door 2, the active sliding door mechanism 1 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.

[0113] For example, as shown in Figures 9 and 10, during the opening of the cabinet door 2, the active sliding door mechanism 1 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.

[0114] Similarly, during the closing process of the cabinet door 2, the active sliding door mechanism 1 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 airtightness.

[0115] In some embodiments, as shown in Figures 1 to 4, the housing 4 has at least two storage spaces, and multiple door assemblies are provided, each door assembly corresponding to one of the storage spaces, so as to drive the door panel 3 to move relative to the corresponding door 2 during the opening or closing of any door 2.

[0116] In this application, the cabinet 4 has at least two storage spaces, which can be set to different storage environments (different temperatures, humidity, etc.) to meet the storage conditions of different items. Each storage space is equipped with a corresponding door assembly, and the cabinet door 2 of the corresponding door assembly can open or close the corresponding storage space, allowing the two storage spaces to be opened or closed independently, making it convenient for users to store or retrieve items within the storage spaces. The door panel 3 of each door assembly can also slide relative to the corresponding cabinet door 2. When the cabinet door 2 is closed, the door panel 3 can be flush with the cabinet on the side, or when the cabinet door 2 is open, the door panel 3 can avoid obstacles on both sides.

[0117] Specifically, the cabinet 4 has a first storage space and a second storage space. Correspondingly, the door assembly also includes a first door assembly and a second door assembly. The door 2 of the first door assembly is rotatably connected to the cabinet 4 to open or close the first storage space, and the door 2 of the second door assembly is rotatably connected to the cabinet 4 to open or close the second storage space.

[0118] Furthermore, the first door assembly and the second door assembly are arranged vertically along the height of the cabinet door 2. The first door assembly is equipped with an active sliding door mechanism 1, a first driven sliding door mechanism 9, and a second driven sliding door mechanism 18. The corresponding door panels 3 and cabinet doors 2 can be moved accordingly using the corresponding active sliding door mechanism 1, the first driven sliding door mechanism 9, and the second driven sliding door mechanism 18. The second door assembly is equipped with an active sliding door mechanism 1, a first driven sliding door mechanism 9, and a second driven sliding door mechanism 18. The corresponding active sliding door mechanism 1, the first driven sliding door mechanism 9, and the second driven sliding door mechanism 18 can be used to control the movement of the corresponding door panels 3 and cabinet doors 2.

[0119] 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.
