[0046] In an embedded furniture, a refrigeration device can be embedded in a cabinet. Among them, a door body 100 of the refrigeration device is rotatably connected to a box body 700 of the refrigeration device. The door body 100 of the refrigeration device can be used to cover an accommodation space inside the box body 700, and a decorative panel 400 can be used to cover the cabinet body of the cabinet, so that the outer surface of the cabinet is combined with the home decoration style.

[0047] However, as the door body 100 of the refrigeration device is opened, the decorative panel 400 is prone to interference and collision with the side wall of the cabinet, resulting in a poor use experience of the embedded refrigerator. Therefore, the present application proposes a door assembly of a refrigeration device to solve the defect that the refrigeration device is prone to interference with the side wall of the cabinet during the door opening process, affecting the use experience.

[0048] It should be noted that the door assembly of the refrigeration device 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 other refrigeration devices with rotational connection. The following mainly describes the door assembly of the refrigeration device of the present application (hereinafter simply referred to as the door assembly) with a refrigerator as the usage scenario.

[0049] The following will be combined with Figures 1 to 6 to describe the door assembly and the refrigeration device of the present application.

[0050] According to an embodiment proposed in the embodiments of the present application, please refer to Figures 1 to 3, the door assembly includes a door body 100 (hereinafter simply referred to as the door body 100), a first rack 200, a connecting rod 300, a decorative plate 400, and a gear assembly 500. One end of the door body 100 is adapted to be rotatably connected to the cabinet 700 of the refrigeration device; the first rack 200 is slidably disposed on the door body 100; one end of the connecting rod 300 is rotatably connected to the first rack 200, and the other end of the connecting rod 300 is rotatably connected to the cabinet 700; the decorative plate 400 is provided with a second rack 600, and the decorative plate 400 is slidably connected to the door body 100; the gear assembly 500 is drivingly connected to the first rack 200 and the second rack 600. When opening the door, the connecting rod 300 rotates and drives the first rack 200 to slide, so that the second rack 600 drives the decorative plate 400 to move away from the rotating side of the door body 100.

[0051] For the door assembly according to the embodiment of the present application, when opening the door, as the door body 100 rotates relative to the cabinet 700, the connecting rod 300 drives the first rack 200 to slide relative to the door body 100. The first rack 200 can drive the gear assembly 500 to rotate, and drive the decorative plate 400 provided with the second rack 600 to slide in the direction away from the rotating side of the door body 100, so as to realize the relative movement between the door body 100 and the decorative plate 400, thereby avoiding interference and collision between the door body 100 and the side wall of the cabinet during the opening and closing process. When closing the door, as the door body 100 rotates relative to the cabinet 700, the connecting rod 300 drives the first rack 200 to slide relative to the door body 100, thereby driving the decorative plate 400 to slide towards the rotating side of the door body 100, realizing the relative movement between the door body 100 and the decorative plate 400, and ensuring that the decorative plate 400 can be normally closed.

[0052] Through the transmission of the connecting rod 300, the first rack 200 and the gear assembly 500 in the present application, the decorative plate 400 can slide relative to the door body 100, thereby avoiding interference during the opening and closing of the door assembly. The structure is simple and the assembly is convenient, which is beneficial to improving the assembly efficiency of the door assembly.

[0053] According to an embodiment of the present application, the door body 100 includes a plate body 110 and a mounting portion 120. The gear assembly 500 includes a rotating shaft 530, a first gear 510 and a second gear 520 sleeved on the rotating shaft 530. The first gear 510 meshes with the first rack 200, and the second gear 520 meshes with the second rack 600. The rotating shaft 530 is rotatably disposed on the mounting portion 120; a first mounting area 501 for mounting the first gear 510 is formed between the plate body 110 and the mounting portion 120, and a second mounting area 502 for mounting the second gear 520 is formed between the mounting portion 120 and the decorative plate 400.

[0054] It can be understood that the gear assembly 500 provides transmission for the first rack 200 and the second rack 600, wherein the first gear 510 is used to mesh with the first rack 200, and the second gear 520 is used to mesh with the second rack 600. The first gear 510 and the second gear 520 are connected by rotation, and when the first rack 200 moves, the first gear 510 can be driven to rotate, and then the second gear 520 can be driven to rotate, so that the second rack 600 moves linearly with the rotation of the second gear 520.

[0055] It is understandable that the plate body 110 and the mounting portion 120 are spaced apart to form a first mounting area 501 for mounting a first gear 510. The mounting portion 120 and the decorative plate 400 are spaced apart to form a second mounting area 502 for mounting a secondary gear.

[0056] In one embodiment, a plurality of intermediate transmission gears are disposed between the first gear 510 and the second gear 520, and the first rack 200 is adapted to drive the first gear 510 to rotate, thereby driving a plurality of intermediate transmission gears to rotate, thereby driving the second gear 520 to rotate. The intermediate transmission gears are disposed between the first gear and the second gear to ensure that the first gear and the second gear have the same direction of rotation.

[0057] According to an embodiment of the present application, please refer to Figure 4 and Figure 5 The gear assembly 500 includes a plurality of transmission-connected gears, the plurality of gears are located in the same plane, and the plurality of gears are staggered along the height direction of the door body 100 .

[0058] It is understandable that the gears are staggered along the height direction of the door body 100, so that multiple gears can run on the same vertical plane, maximizing the use of vertical space and making the overall structure more compact. Multiple gears are located in the same plane, the distance between the door body 100 and the decorative plate 400 is closer, the overall structure of the door assembly is more compact, the space required for installation is reduced, and the user experience is better.

[0059] According to one embodiment of the present application, the door body 100 is installed with a first slide rail 130 and a second slide rail 140 , the first rack 200 is slidably connected to the first slide rail 130 , and the second rack 600 is slidably connected to the second slide rail 140 .

[0060] It is understandable that the first slide rail 130 and the second slide rail 140 can provide smooth and stable linear motion, and when the first rack 200 slides relative to the door body 100, the first rack 200 can move linearly along the extension direction of the first slide rail 130. When the second rack 600 slides relative to the door body 100, the second rack 600 can move linearly along the extension direction of the second slide rail 140.

[0061] In one embodiment, the first slide rail 130 includes a first upper slide rail and a first lower slide rail. The first rack 200 is slidably connected to the first upper slide rail and the first lower slide rail, and the first upper slide rail and the first lower slide rail are arranged opposite to each other.

[0062] It can be understood that the first rack 200 is simultaneously connected to the first upper slide rail and the first lower slide rail. The first upper slide rail and the first lower slide rail can provide greater supporting force for the first rack 200, thereby greatly improving the stability of the door assembly. The first upper slide rail and the first lower slide rail can also effectively prevent the rack from shaking or deviating from the first slide rail 130 and the second slide rail 140 during movement, realizing stable upper and lower limit positions.

[0063] According to an embodiment of the present application, the first slide rail 130 is provided with a first limiting portion 131, and the first rack 200 is provided with a first limiting groove 210. The first limiting portion 131 is snap-connected to the first limiting groove 210.

[0064] It can be understood that the snap connection between the first limiting portion 131 and the first limiting groove 210 can effectively limit the movement range of the first rack 200 relative to the door body 100 during the sliding process.

[0065] It should be noted that the shape of the first limiting portion 131 can be an I-shaped structure, or a spindle shape or other limiting structures. The first limiting groove 210 is arranged corresponding to the shape of the first limiting portion 131.

[0066] According to an embodiment of the present application, the second slide rail 140 is provided with a second limiting portion 141, and the decorative plate 400 is provided with a second limiting groove 410. The second limiting portion 141 is snap-connected to the second limiting groove 410.

[0067] It can be understood that the snap connection between the second limiting portion 141 and the second limiting groove 410 can effectively limit the movement range of the decorative plate 400 relative to the door body 100 during the sliding process.

[0068] It should be noted that the shape of the second limiting portion 141 can be an I-shaped structure, or a spindle shape or other limiting structures. The second limiting groove 410 is arranged corresponding to the shape of the second limiting portion 141.

[0069] According to an embodiment of the present application, a rotating portion is formed at one end of the door body 100, and the rotating portion is rotatably connected to the box body 700.

[0070] It can be understood that the rotating portion can be a rotating shaft 530 or a rotating hole, and the box body 700 can rotate relative to the door body 100 through the rotating portion.

[0071] According to an embodiment of the present application, the module of the second gear 520 is greater than the module of the first gear 510.

[0072] It can be understood that the larger the module, the greater the pitch (i.e., the distance between teeth) of the gear or rack, which will cause the linear displacement distance of the gear or rack to increase when rotating one circle or moving a certain distance. That is, at the same rotation angle, the displacement distance of the second rack 600 is greater than that of the first rack 200. The larger displacement distance can reduce the transmission error and improve the adaptability of the door assembly.

[0073] According to an embodiment of the present application, the first rack 200 and the second rack 600 are arranged in parallel and are located on opposite sides of the gear assembly 500.

[0074] It can be understood that the first rack 200 and the second rack 600 arranged in parallel can better balance the load and the reaction force mechanically, which helps to reduce the imbalance between the torque and the reaction torque in the transmission door assembly, thereby improving the stability and reliability of the door assembly.

[0075] Arranging the first rack 200 and the second rack 600 on both sides of the gear assembly 500 can make more effective use of the space between the door body 100 and the decorative panel 400, which is easy to install the first rack 200 and the second rack 600, and the operator can adjust the first rack 200 and the second rack 600 more easily.

[0076] It should be noted that the decorative panel 400 and the refrigeration equipment are manufactured by different manufacturers respectively, and based on the user's selection, there will be different models of refrigeration equipment and the decorative panel 400 of the cabinet for assembly. The gear assembly 500, the first rack 200 and the second rack 600 of the present application are located between the door body and the decorative panel 400, and the first rack 200 and the second rack 600 are arranged on both sides of the gear assembly 500, which can reduce the difficulty of production and manufacturing and at the same time reduce the difficulty of assembly.

[0077] For the refrigeration equipment according to the second aspect embodiment of the present application, please refer to Figures 1 to 6 , the refrigeration equipment includes a box body 700 and the above-mentioned door assembly. The box body 700 forms an accommodation space, and the door assembly is rotatably arranged on the box body 700 to open or close the accommodation space.

[0078] It should be noted that since the refrigeration equipment of the present application includes the above-mentioned door assembly, it has all the technical effects of the above-mentioned door assembly, which will not be elaborated here.

[0079] According to an embodiment of the present application, the box body 700 is provided with a first rotating part 710 and a second rotating part 720. The door body 100 is rotatably connected to the first rotating part 710, and the connecting rod 300 is rotatably connected to the second rotating part 720. When the door body 100 is closed, the first rotating part 710 is located on the side of the second rotating part 720 closer to the user, and the second rotating part 720 is located between the first rotating part 710 and the first rack 200.

[0080] It can be understood that the door body 100 is rotatably connected to the box body 700 through the first rotating part 710, and the second rotating part 720 is adapted to provide a connection position for the rotational connection of the connecting rod 300. When the door body 100 rotates relative to the box body 700, the connecting rod 300 drives the first rack 200 to slide relative to the door body 100. The first rack 200 can drive the gear assembly 500 to rotate and drive the decorative plate 400 installed with the second rack 600 to slide, so as to realize the relative movement between the door body 100 and the decorative plate 400. When the door body 100 is closed, the second rotating part 720 is located between the first rotating part 710 and the first rack 200, avoiding the interference between the connecting rod 300 and the first rotating part 710. Specifically, reference can be made to Figure 3 , Figure 3 which is a schematic top view structure diagram of the door assembly when the door body 100 is closed. When the door body 100 is closed, the second rotating part 720 is located between the first rotating part 710 and the first rack 200.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application, and should all be covered within the scope of the claims of the present application.
