[0037] In an embedded furniture, a refrigeration device can be embedded in a cabinet, wherein a cabinet door 4 is rotatably connected to a cabinet body of the cabinet, and the cabinet door 4 can be used to cover the cabinet body, so as to combine the outer surface of the cabinet with the home decoration style. The refrigeration device can be embedded in the cabinet, wherein a door 2 of the refrigeration device is rotatably connected to a box body 1 of the refrigeration device, and the door 2 of the refrigeration device can be used to cover an accommodation space inside the box body 1. The cabinet door 4 is rotatably connected to the cabinet body.

[0038] It should be noted that the door body assembly proposed in the present application can be used for the door body of a refrigerator, can also be used for the door body of a freezer, or the door body of other refrigeration devices with a rotational connection. The following describes the door body assembly of the present application with a refrigerator as the usage scenario.

[0039] The following will be combined with Figures 1 to 5 to describe the door body assembly and the refrigeration device of the present application.

[0040] The door body assembly proposed in the embodiment of the first aspect of the present application includes a box door 2, a sliding door mechanism 3, a cabinet door 4, a spring assembly 5 and a roller assembly 6. The box door 2 is suitable for being rotatably connected to the box body 1 of the refrigeration equipment, the sliding door mechanism 3 is slidably connected to the box door 2, the cabinet door 4 is slidably connected to the box door 2, the cabinet door 4 slides relative to the box door 2 through the sliding door mechanism 3, the spring assembly 5 is arranged between the sliding door mechanism 3 and the cabinet door 4, at least one of the sliding door mechanism 3 and the cabinet door 4 is provided with a roller assembly 6, the roller assembly 6 is in rolling contact with the box door 2, and during the door opening process, the box door 2 drives the cabinet door 4 to move toward the rotating side away from the box door 2 through the sliding door mechanism 3, and squeezes the spring assembly 5, and the roller assembly 6 rolls on the box door 2.

[0041] According to the door assembly of the embodiment of the present application, when the door is opened, as the box door 2 rotates relative to the box body 1, the sliding door mechanism 3 slides relative to the box door 2 at this time, thereby driving the cabinet door 4 to slide relative to the box door 2 through the spring assembly 5. The cabinet door 4 moves in the direction away from the rotating side of the box door 2, thereby avoiding the edge of the cabinet door 4 from interfering with the box door 2 or the cabinet body of the cabinet. At the same time, the sliding door mechanism 3 drives the cabinet door 4 to move through the spring assembly 5, and can flexibly transfer force to the cabinet door 4, effectively reducing the occurrence of problems such as wear and jamming. In addition, when the cabinet door 4 moves relative to the box door 2, it moves relative to the roller assembly 6, which has less friction, and the cabinet door 4 moves more smoothly, improving the user's experience. When closing the door, as the box door 2 rotates relative to the box body 1, the sliding door mechanism 3 can also drive the cabinet door 4 to slide, realizing the relative movement between the box door 2 and the cabinet door 4, ensuring that the cabinet door 4 can be closed normally.

[0042] Please refer to Figure 1 and Figure 2 The following describes the structure in which the box door 2 and the cabinet door 4 slide relative to each other through the sliding door mechanism 3:

[0043] According to one embodiment of the present application, it should be noted that one side of the cabinet door 2 is rotatably connected to the cabinet body 1, and the position of its rotation axis is the rotation side of the cabinet door 2, and the function of the sliding door mechanism 3 is to drive the cabinet door 4 to move away from the rotation side of the cabinet door 2 during the opening process of the cabinet door 2, so as to avoid interference between the cabinet door 4 and the side wall of the cabinet, the cabinet door 2 or the cabinet body 1.

[0044] The sliding door mechanism 3 includes a first slider 32, a connecting rod 31 and a second slider 33. The first slider 32 is slidably installed on the door 2. One end of the connecting rod 31 is rotatably connected to the first slider 32, and the other end is rotatably connected to the cabinet 1 of the refrigeration device. The second slider 33 is slidably installed on the door 2 and connected to the cabinet door 4. The spring assembly 5 is arranged between the second slider 33 and the cabinet door 4. The second slider 33 is connected to the first slider 32 through a transmission component. During the door opening process, the connecting rod 31 moves to drive the first slider 32 to slide relative to the door 2, and drives the second slider 33 to slide in a direction away from the rotating side through the transmission component.

[0045] That is to say, the swing of the connecting rod 31 can push the first slider 32 to slide on the box body 1, and through the transmission component, the first slider 32 can drive the second slider 33 to also slide relative to the box body 1, so that the cabinet door 4 connected to the second slider 33 moves correspondingly relative to the box door 2, realizing the translation of the cabinet door 4 away from the rotating side of the box door 2. It can be understood that through the transmission of the connecting rod 31, the first slider 32 and the second slider 33, the cabinet door 4 can slide relative to the box door 2, thus avoiding the interference generated by the opening and closing of the door body assembly, with a simple structure and convenient assembly, which is beneficial to improving the assembly efficiency of the door body assembly.

[0046] According to an embodiment of the present application, the first slider 32 is provided with a first rack 321, the second slider 33 is provided with a second rack 332, the transmission component includes a first gear 34 and a second gear 35, the first gear 34 meshes with the first rack 321, the second gear 35 is coaxially arranged with the first gear 34, and the second gear 35 meshes with the second rack 332.

[0047] It can be understood that the first rack 321 is arranged on the side of the first slider 32 facing the first gear 34. Teeth can be arranged on the first slider 32 to form the first rack 321, and the same applies to the second rack 332. The first gear 34 and the second gear 35 can be coaxially connected through a transmission shaft to rotate synchronously. That is, when the connecting rod 31 pushes the first slider 32 and the first rack 321 moves, it pushes the first gear 34 to rotate, so that the second gear 35 rotates synchronously, and further drives the second rack 332 to move, realizing the drive of the cabinet door 4. The first slider 32 and the second slider 33 can slide on the box door 2 through ways such as slide rails and pulleys to reduce friction and facilitate directional sliding.

[0048] According to an embodiment of the present application, the first rack 321 and the second rack 332 are arranged in parallel, and the first rack 321 and the second rack 332 are located on opposite sides of the axis of the first gear 34.

[0049] It should be noted that the parallel arrangement here refers to the parallel arrangement of the intervals of the teeth, so that the first rack 321 and the second rack 332 move on parallel paths. It can be understood that the first rack 321 and the second rack 332 arranged in parallel can better balance the load and the reaction force in mechanics, which helps to reduce the imbalance between the torque and the reaction torque in the transmission door body assembly, thereby improving the stability and reliability of the door body assembly.

[0050] It can be understood that the first rack 321 and the second rack 332 are respectively arranged on opposite sides of the axis of the first gear 34, that is, on the opposite sides of the first gear 34 and the second gear 35. At this time, the teeth of the first rack 321 and the second rack 332 are arranged facing each other. For example, the teeth of the first rack 321 face downward, and the teeth of the second rack 332 face upward. In this way, under the rotation of the first gear 34 and the second gear 35 in the same direction, the first rack 321 and the second rack 332 move in opposite directions, so as to realize the movement of the cabinet door 4 in the direction away from the rotating side of the box door 2. In addition, the space between the box door 2 and the cabinet door 4 can be utilized more effectively, which is conducive to the installation of the first rack 321 and the second rack 332, and the operator can adjust the first rack 321 and the second rack 332 more easily.

[0051] It should be noted that the cabinet door 4 and the refrigeration device are respectively manufactured by different manufacturers, and based on the user's choice, different models of refrigeration devices and the cabinet door 4 of the cabinet will be assembled. The gear assembly, the first rack 321 and the second rack 332 of the present application are located between the box door 2 and the cabinet door 4, and the first rack 321 and the second rack 332 are arranged on both sides of the gear assembly, which can reduce the difficulty of production and manufacturing and at the same time reduce the difficulty of assembly.

[0052] When closing the door, as the box door 2 rotates relative to the box body 1, the connecting rod 31 drives the first rack 321 to slide in the opposite direction relative to the box door 2, thereby driving the cabinet door 4 to slide in the opposite direction, realizing the relative movement between the box door 2 and the cabinet door 4, and ensuring that the cabinet door 4 can be normally closed.

[0053] In one embodiment, the box door 2 is provided with a first slide rail 25 and a second slide rail 26. The first slide rail 25 and the second slide rail 26 are spaced apart in the height direction of the box door 2. The first slider 32 is slidably connected to the first slide rail 25, and the second slider 33 is slidably connected to the second slide rail 26. By sliding the first slider 32 on the first slide rail 25 and the second slider 33 on the second slide rail 26, the smoothness of the box door 2 relative to the door body 21 during the sliding process can be ensured, and the shaking and noise can be reduced. It should be noted that here the slide rail can be in the structural form of a chute or a slide bar, which is not limited here, as long as it can enable the corresponding structure to slide on the slide rail. For example, the slide rail is a kind of track, and the slider is a sliding member adapted to the slide rail and can slide along the slide rail.

[0054] In one embodiment, the first slide rail 25 is provided with one of a first limiting portion and a first limiting groove, and the first slider 32 is provided with the other of the first limiting portion and the first limiting groove, and the first limiting portion and the first limiting groove are snap-connected.

[0055] It should be noted that the shape of the first limiting portion can be an I-shaped structure, or a spindle shape or other limiting structures, and the first limiting groove can be set corresponding to the shape of the first limiting portion.

[0056] In one embodiment, one of the second limiting portion and the second limiting groove is provided on the second sliding rail 26, and the other of the second limiting portion and the second limiting groove is provided on the second sliding block 33, and the second limiting portion and the second limiting groove are snap-connected.

[0057] It should be noted that the shape of the second limiting portion can be an I-shaped structure, or a spindle shape or other limiting structures, and the second limiting groove can be set corresponding to the shape of the second limiting portion.

[0058] According to an embodiment of the present application, the box door 2 includes a door body 21 and a mounting portion 22 connected to each other, and the rotating shaft is rotatably provided on the mounting portion 22; a first mounting area for mounting the first gear 34 is formed between the door body 21 and the mounting portion 22, and a second mounting area for mounting the second gear 35 is formed between the mounting portion 22 and the cabinet door 4.

[0059] It can be understood that the door body 21 and the mounting portion 22 are spaced apart to form a first mounting area for mounting the first gear 34. The mounting portion 22 and the cabinet door 4 are spaced apart to form a second mounting area for mounting the second gear 35.

[0060] In other embodiments, the first gear 34 and the second gear 35 may not be coaxially arranged through a transmission shaft, but an intermediate transmission gear is provided between the first gear 34 and the second gear 35. The intermediate transmission gear meshes with the first gear 34 and the second gear 35 respectively. The first rack 321 is adapted to drive the first gear 34 to rotate, and then drive the intermediate transmission gear to rotate, so as to drive the second gear 35 to rotate. The intermediate transmission gear is provided between the first gear 34 and the second gear 35 to ensure that the first gear 34 and the second gear 35 rotate in the same direction.

[0061] It can be understood that the door body 21 constitutes the basic shape and appearance of the box door 2, and the mounting portion 22 is connected to the door body 21 in an L-shaped structure for mounting the sliding door mechanism 3. The mounting portion 22 can be designed as a structure integrally formed with the door body 21, or can be fixedly connected to the door body 21 by welding, bolt connection or other means.

[0062] Please refer to Figure 2 and Figure 4 , and the related structure of the spring assembly 5 will be introduced below:

[0063] According to an embodiment of the present application, the sliding door mechanism 3 and the cabinet door 4 are connected by a spring assembly 5. That is, the sliding door mechanism 3 drives the cabinet door 4 to move in a corresponding direction by squeezing and pushing the spring assembly 5. In this way, the spring assembly 5 will be continuously compressed, and the force will be flexibly transmitted to the cabinet door 4, which can reduce the occurrence of phenomena such as wear and jamming, and improve the user experience. The spring assembly 5 can effectively avoid the wear, jamming and other situations caused by the rigid connection between the sliding door mechanism 3 and the cabinet door 4.

[0064] In one embodiment, the spring assembly 5 is a first spring 53. The first spring 53 extends along the moving direction of the cabinet door 4. One end of the first spring 53 abuts against the sliding door mechanism 3, and the other end abuts against the cabinet door 4. The compression direction of the first spring 53 is the same as the moving direction of the roller assembly 6. When the sliding door mechanism 3 drives the cabinet door 4 to move, the sliding door mechanism 3 squeezes the first spring 53 to flexibly transmit the force to the cabinet door 4, and the cabinet door 4 realizes the movement. In order to realize the sliding of the cabinet door 4 relative to the box door 2, the cabinet door 4 can be installed on the slide rail of the box door 2, so that the slide rail supports the cabinet door 4 to perform corresponding sliding.

[0065] According to an embodiment of the present application, a first mounting platform 41 is provided on the side of the cabinet door 4 facing the sliding door mechanism 3, and a mounting protrusion 331 is provided on the side of the sliding door mechanism 3 facing the cabinet door 4. The first mounting platform 41 and the mounting protrusion 331 are arranged in a straight line in the sliding direction of the cabinet door 4, and the first spring 53 is arranged between the first mounting platform 41 and the mounting protrusion 331.

[0066] It can be understood that the connecting direction of the first mounting platform 41 and the mounting protrusion 331 is parallel to the sliding direction of the cabinet door 4. The first spring 53 is clamped between the first mounting platform 41 and the mounting protrusion 331, which is convenient for installing and fixing the first spring 53. One end of the first spring 53 is connected to the first mounting platform 41, and the other end is connected to the mounting protrusion 331. The connection method can be snap connection, bonding, plug connection, etc., which is not limited here.

[0067] According to an embodiment of the present application, the spring assembly 5 and the roller assembly 6 are arranged at intervals in the vertical direction, reasonably utilizing the space in the vertical direction of the box door 2. Exemplarily, the spring assembly 5 is located above the roller assembly 6, and the roller assembly 6 rolls and abuts against the box door 2, so as to reduce the friction generated by the movement of the cabinet door 4 relative to the box door 2. The spring assembly 5 is used to buffer the mutual acting force between the sliding door mechanism 3 and the cabinet door 4, and improve the user experience.

[0068] According to an embodiment of the present application, the spring assembly 5 has installation gaps with the sliding door mechanism 3 and the cabinet door 4 respectively, so that the cabinet door 4 is carried on the box door 2 through the roller assembly 6. It should be noted that the cabinet door 4 rolls and abuts against the box door 2 through the roller assembly 6, and there is an installation and cooperation relationship between the roller assembly 6 and the box door 2. Setting the spring assembly 5 to have installation gaps with the sliding door mechanism 3 and the cabinet door 4 respectively can better adapt to the cooperation relationship between the roller assembly 6 and the box door 2, without separately adjusting the installation positions of the roller assembly 6 and the spring assembly 5, so that both are adapted to be connected to the box door 2. Specifically, if the moving direction of the cabinet door 4 is the horizontal direction, the installation gap is in the vertical direction of the spring assembly 5, which will not affect the normal pushing of the spring assembly 5 by the sliding door mechanism 3 to drive the cabinet door 4 to move.

[0069] According to an embodiment of the present application, a second installation platform 42 is further provided on the side of the cabinet door 4 facing the sliding door mechanism 3. The second installation platform 42 and the first installation platform 41 are spaced apart in the sliding direction of the cabinet door 4. The installation protrusion 331 is inserted between the first installation platform 41 and the second installation platform 42. The spring assembly 5 further includes a second spring 54, and the second spring 54 is arranged between the second installation platform 42 and the installation protrusion 331.

[0070] It can be understood that during the door opening process, the sliding door mechanism 3 drives the installation protrusion 331 to move towards the direction of the first spring 53, and during the door closing process, the sliding door mechanism 3 drives the installation protrusion 331 to move towards the direction of the second spring 54, so as to achieve the transmission of flexible force during both opening and closing of the door, and improve the user experience of opening and closing the door.

It can be understood that the convex portion 271 is located inside the support chute 431, and the second roller 62 rolls and abuts against the convex portion 271, which can achieve a clamping effect, so that the connection between the support slide table 43 and the support slide rail 27 is stable and not easy to loosen. Specifically, the distribution of the first roller 61 and the second roller 62 inside and outside the support chute 431 is beneficial to balancing the internal and external forces of the support slide table 43 and improving the support stability of the support slide table 43.

[0089] According to an embodiment of the present application, the roller assembly 6 includes a sliding door roller 64. The sliding door roller 64 is arranged on the sliding door mechanism 3, and the sliding door roller 64 rolls on the box door 2 as the sliding door mechanism 3 moves; it can be understood that the sliding door roller 64 is used to support the movement of the sliding door mechanism 3 relative to the box door 2. The sliding door roller 64 drives at least a part of the sliding door mechanism 3 to slide relative to the box door 2, and the sliding smoothness of the sliding door mechanism 3 is higher, which is beneficial to reducing wear and jamming between the two.

[0090] According to an embodiment of the present application, the sliding door mechanism 3 is provided with an avoidance groove 333, and a portion of the sliding door roller 64 is accommodated in the avoidance groove 333. The avoidance groove 333 can provide a certain accommodation space for the sliding door roller 64 to avoid the sliding door roller 64 being completely exposed to the outside, which can save installation space and make the structure more compact. It can be understood that the sliding door roller 64 is parallel to the rolling direction of the first roller 61 and the second roller 62.

[0091] According to an embodiment of the present application, the avoidance groove 333 extends along the sliding direction of the cabinet door 4, and the roller assembly 6 includes at least two sliding door rollers 64, and the at least two sliding door rollers 64 are arranged at intervals along the extending direction of the avoidance groove 333. Using at least two sliding door rollers 64 to roll against the cabinet door 2 is conducive to improving the support stability of the sliding door mechanism 3 and the cabinet door 2 and the sliding stability of the sliding door mechanism 3.

[0092] According to one embodiment of the present application, the box door 2 includes a horizontal portion 23 and a vertical portion 24 connected to each other, the horizontal portion 23 extends in the horizontal direction, the vertical portion 24 extends in the vertical direction, the sliding door mechanism 3 is located above the horizontal portion 23, the sliding door roller 64 is provided at the bottom of the sliding door mechanism 3, and the sliding door roller 64 rolls on the horizontal portion 23.

[0093] Exemplarily, the upper part of the cabinet door 2 is bent or concave to form a mounting portion 22, and the mounting portion 22 forms a concave space, where the sliding door mechanism 3 can be installed. In this way, the horizontal portion 23 is located below the sliding door mechanism 3, which can be used to carry the sliding door mechanism 3, prevent the sliding door mechanism 3 from falling, and the installation structure is more stable. Specifically, the sliding door roller 64 is placed vertically, and its lower part rolls against the horizontal portion 23, which can effectively support at least part of the sliding door mechanism 3 to move along the horizontal portion 23, thereby driving the cabinet door 4 to move along the cabinet door 2, and the movement is stable. At the same time, the vertical portion 24 is arranged at a right angle to the horizontal portion 23, and the vertical portion 24 can be used to support the cabinet door 4 facing the side of the cabinet door 2, so as to prevent the cabinet door 4 from swinging in the direction of the cabinet door 2, and keep the cabinet door 4 and the cabinet door 2 relatively parallel. Exemplarily, the first roller 61 and the second roller 62 can roll against the vertical portion 24.

[0094] In one embodiment, the roller assembly 6 further includes a third roller 63, which is disposed on the cabinet door 4 and is used to roll and abut against the vertical wall of the box door 2 to keep the cabinet door 4 relatively parallel to the box door 2 when the cabinet door 4 slides relative to the box door 2, and the sliding is smooth. Specifically, the third roller 63 is connected to the cabinet door 4, and the axis of the third roller 63 is parallel to the vertical wall of the box door 2.
