Description

Technical Field

[0001] This application relates to the field of refrigeration equipment structure technology, and in particular to a tilting beam drive mechanism, a door assembly, and a refrigeration device. Background Technology

[0002] With the development of refrigerator technology and the improvement of people's living standards, larger-capacity side-by-side refrigerators are gradually becoming a part of people's lives. To prevent cold air from leaking out from the gap between the two refrigerator doors, a flip-up beam is often installed on one of the doors. When the refrigerator door is closed, the flip-up beam can flip to the open position, thus tightly fitting the door frame or the other door, effectively sealing the gap and preventing cold air leakage.

[0003] To enable the flip beam to automatically flip during door opening and closing, existing refrigerators have guide blocks on the cabinet corresponding to the position of the flip beam. These guide blocks have curved guide grooves. During door closing, the top of the flip beam extends into the curved guide groove of the guide block and flips under the action of the curved guide groove.

[0004] During the opening and closing process, the top of the flip beam slides into contact with the curved guide groove, which exerts motion resistance on the flip beam. This results in greater resistance when opening and closing the refrigerator door equipped with the flip beam. Furthermore, noise is generated during the closing or opening of the refrigerator door due to the sliding contact between the guide block and the flip beam, affecting the user experience.

[0031] The flip beam drive mechanism provided in this application connects the transmission component to the hinge component and the flip beam component respectively. When the first door component rotates relative to the hinge component, the positional change of the first door component relative to the hinge component drives the transmission component and the flip beam component, thereby causing the flip beam component to flip, so that the flipping of the flip beam component is linked with the rotation of the first door component. The flipping of the flip beam component in this application does not require the use of guide blocks on the housing, which avoids the problems of high opening and closing resistance and noise generation that exist when the flip beam cooperates with the guide block, thus improving the user experience.

[0032] The door assembly and refrigeration equipment provided in this application both include the above-mentioned flip beam drive mechanism. The relative position change between the first door assembly and the hinge assembly can drive the movement of the components in the transmission assembly, thereby causing the flip beam assembly to flip. Therefore, it naturally possesses the technical effects of the above-mentioned flip beam drive mechanism. Attached Figure Description

[0061] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0062] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0063] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0064] To address the technical problems of high switching resistance and noise generation when using guide blocks to automatically flip the flip beam in existing technologies, this application provides a flip beam driving mechanism that eliminates the need for guide blocks on the refrigerator body 6. The mechanism is connected to the hinge assembly 2 and the flip beam assembly 3 via a transmission component 4. The transmission component 4 and the flip beam assembly 3 are driven by the positional change of the first door assembly 1 relative to the hinge assembly 2. This enables the automatic flipping of the flip beam assembly 3 during the opening and closing of the first door assembly 1, avoiding the problems of high switching resistance and noise generation caused by guide blocks.

[0065] Please see Figures 1 to 18 The first aspect of this application provides a tilting beam drive mechanism, including a first door assembly 1, a hinge assembly 2, a tilting beam assembly 3, and a transmission assembly 4. The first door assembly 1 includes a mounting side and a rotating side positioned opposite each other. The hinge assembly 2 is disposed on the mounting side and rotatably connected to the first door assembly 1, allowing the first door assembly 1 to rotate relative to the hinge assembly 2, thereby achieving the switching between an open and closed state. Figure 1 , Figure 13 and Figure 16 As shown.

[0066] The tilting beam assembly 3 is located on the rotating side and is rotatably connected to one side of the first door assembly 1. When the first door assembly 1 is in the open and closed states, the tilting beam assembly 3 has different tilting positions relative to the first door assembly 1, such as... Figure 14 , Figure 15 , Figure 17 and Figure 18 As shown, where Figure 15 and Figure 18 The dotted line indicates the sealing position of the tilting beam assembly 3 (i.e., the position where the tilting beam assembly 3 is tilted to the unfolded state for sealing and contact). Figure 15 The arrow in the diagram indicates the flipping direction (i.e., rotation direction) of the flipping beam assembly 3. Specifically, when the first door assembly 1 is in the open state, the flipping beam assembly 3 flips to a state of contact with the side edge of the first door assembly 1 (hereinafter referred to as the contact state), as shown in the diagram. Figure 14 and Figure 15 As shown; when the first door assembly 1 is in the closed state, the tilting beam assembly 3 tilts to the unfolded state, as shown. Figure 17 and Figure 18 As shown, the flip beam assembly 3 can achieve the effect of sealing gaps.

[0067] The transmission component 4 is mounted on the first door assembly 1. The transmission component 4 is connected to the hinge assembly 2 and the flip beam assembly 3 respectively. The flip beam assembly 3 is used to flip as the first door assembly 1 rotates relative to the hinge assembly 2. The relative position change between the first door assembly 1 and the hinge assembly 2 drives the components in the transmission component 4 to move, thereby driving the flip beam assembly 3 to flip, so that the flipping of the flip beam assembly 3 is linked with the rotation of the first door assembly 1.

[0068] It should be noted that the flipping beam assembly 3 of this application does not need to be flipped through a guide block, which can avoid the problems of high switching resistance and noise that exist when the flipping beam and the guide block are in contact, thus improving the user experience.

[0069] In the above embodiments, the transmission component 4 may include a linkage component, a gear component, a synchronous belt component, etc. As long as the flipping beam component 3 can be linked with the rotation of the first door component 1, the purpose of this application can be achieved.

[0070] In some embodiments of this application, please refer to Figure 1 , Figure 2 and Figure 10 The transmission assembly 4 includes a first sliding member 41 and a first connecting rod 42. The first sliding member 41 is slidably mounted on the first door assembly 1. The first connecting rod 42 is hinged to the first sliding member 41 and the flip beam assembly 3, respectively, and can connect the first sliding member 41, the first connecting rod 42 and the flip beam assembly 3 into a three-bar linkage structure. During the closing process of the first door assembly 1, the first sliding member 41 drives the first connecting rod 42 to push the flip beam assembly 3 to flip to the unfolded state, so that the flip beam assembly 3 can flip to the inside of the first door assembly 1 (the inside is the side closer to the box 6) to achieve a gap seal between the first door assembly 1 and other doors or door frames.

[0071] Specifically, the first door assembly 1 rotates relative to the hinge assembly 2 while simultaneously driving the sliding motion of the first sliding member 41. This sliding motion can be achieved through indirect transmission via other components, or by the first sliding member 41 directly contacting the hinge assembly 2. The sliding motion of the first sliding member 41, through the relative positional change between the hinge assembly 2 and the first sliding member 41, drives the first sliding member 41 to slide. The sliding motion of the first sliding member 41 then causes a positional change in the first connecting rod 42, which in turn pushes or pulls the flipping beam assembly 3 to flip.

[0072] In some embodiments of this application, please refer to Figure 2 and Figure 10 The tilting beam assembly 3 includes a tilting beam body 31 and a hinge seat 32, wherein the hinge seat 32 is fixedly mounted on the first door assembly 1, and the tilting beam body 31 is hinged to the hinge seat 32, allowing the tilting beam body 31 to tilt relative to the first door assembly 1. The tilting beam body 31 is provided with a first connecting shaft 311 for hinged connection with a first connecting rod 42, and a first sliding member 41 has a third connecting shaft 413 for hinged connection with the first connecting rod 42 at one end near the tilting beam body 31. The first sliding member 41 extends along the length direction of the first door assembly 1 (i.e.,...). Figure 2 When sliding in the left and right directions, the main body 31 of the flip beam can be pushed and pulled by the first connecting rod 42, thereby realizing the flip beam main body 31 flipping relative to the first door assembly 1.

[0073] In some embodiments of this application, please refer to Figure 3 and Figure 10One or more hinge seats 32 are provided in the height direction of the first door body assembly 1 for stable connection with the tilting beam body 31. The hinge seat 32 includes a seat body 321 and a second connecting shaft 322. The tilting beam body 31 is provided with a groove that matches the hinge seat 32. The side wall of the groove is provided with a fourth hinge hole 312 for hinged with the second connecting shaft 322, so as to realize the tilting beam body 31 relative to the hinge seat 32.

[0074] In some embodiments of this application, please refer to Figure 2 , Figure 3 and Figure 11 The first sliding member 41 is provided with a first rack portion 411, which extends along the sliding direction of the first sliding member 41 and can be used to drive the first sliding member 41 to slide. The transmission assembly 4 also includes a first gear member 43 rotatably disposed on the first door assembly 1. During the closing process of the first door assembly 1, the first gear member 43 rotates in the forward direction; during the opening process of the first door assembly 1, the first gear member 43 rotates in the reverse direction. The first gear member 43 is meshed with the first rack portion 411, and the rotation of the first gear member 43 drives the first rack portion 411 to slide. When the first gear member 43 rotates in the forward direction, it pushes the first rack portion 411 and the first sliding member 41 towards the flip beam assembly 3, causing the flip beam body 31 to flip to the unfolded state; when the first gear member 43 rotates in the reverse direction, it pushes the first rack portion 411 and the first sliding member 41 away from the flip beam assembly 3, causing the flip beam body 31 to flip to the closed state.

[0075] It should be noted that in order to achieve the rotational drive of the first gear component 43 through the opening and closing of the first door assembly 1, the displacement / angle change of the first door assembly 1 relative to the hinge assembly 2 can be converted into torque output through mechanisms such as connecting rods, gear racks, and cams. As long as the rotational drive of the first gear component 43 can be achieved, the purpose of this application can be achieved.

[0076] In some embodiments of this application, please refer to Figure 3 , Figure 6 , Figure 7 and Figure 11The transmission assembly 4 also includes a connector 44, a first transmission component 45, and a second transmission component 46. The connector 44 is fixedly connected to the hinge shaft 21 of the hinge assembly 2. When the first door assembly 1 rotates relative to the hinge shaft 21, the relative position of the connector 44 and the first door assembly 1 also changes. The first transmission component 45 and the second transmission component 46 are both movably mounted on the first door assembly 1, and the first transmission component 45 is connected to the connector 44 and the second transmission component 46 respectively. When the position of the first door assembly 1 relative to the hinge shaft 21 and the connector 44 changes, the positions of the first transmission component 45 and the second transmission component 46 connected to the connector 44 relative to the first door assembly 1 also change. Figure 15 and Figure 18 As shown. During the closing process of the first door assembly 1, the second transmission component 46 drives the first sliding component 41 to slide, thereby realizing the push and pull of the first sliding component 41 on the flip beam assembly 3, and thus realizing the flip beam body 31 in the flip beam assembly 3 to flip.

[0077] In some embodiments of this application, please refer to Figure 6 The connector 44 is provided with a third connecting hole 442 for the hinge shaft 21 to pass through. In order to keep the connector 44 and the hinge shaft 21 relatively fixed, the cross section of the third connecting hole 442 can be a non-circular cross section (such as D-shaped, polygonal, elliptical, etc.). Alternatively, a limiting part 443 (specifically a limiting pin, limiting block, etc.) or a key can be provided on the inner wall of the third connecting hole 442. As long as the relative position between the hinge shaft 21 and the connector 44 remains unchanged during the rotation of the door body 12, thereby changing the position of the connector 44, the first transmission member 45 and the second transmission member 46 relative to the door body 12, the purpose of this application can be achieved.

[0078] In some embodiments of this application, please refer to Figure 3 , Figure 11 , Figure 14 , Figure 15 , Figure 17 and Figure 18 The first transmission member 45 is the second link, which is hinged to the connecting member 44 and the second transmission member 46 to form a three-bar structure, which drives the second transmission member 46 to rotate relative to the first door assembly 1, thereby driving the first sliding member 41 to slide through the rotation of the second transmission member 46.

[0079] It should be noted that the second transmission member 46 can drive the first sliding member 41 to slide by directly engaging with the first rack portion 411 on the first sliding member 41, or it can achieve indirect transmission by setting other transmission components between the second transmission member 46 and the first sliding member 41, both of which can achieve the purpose of this application.

[0080] In some embodiments of this application, please refer to Figure 6 , Figure 8 , Figure 11 , Figure 14 , Figure 15 , Figure 17 and Figure 18 The connector 44 has an eccentrically set first connecting hole 441, and the second transmission member 46 has an eccentrically set second connecting hole 461. The two ends of the second connecting rod are respectively hinged to the first connecting hole 441 and the second connecting hole 461, so that the two ends of the second connecting rod can form an eccentricity with the rotation axis of the first door assembly 1 and the rotation axis of the second transmission member 46, respectively. By adjusting the eccentricity and the length of the connecting rod body 451 on the second connecting rod, the rotation phase difference of the second transmission member 46 relative to the connector 44 can be precisely controlled, thereby realizing the precise driving of the first sliding member 41.

[0081] In some embodiments of this application, please refer to Figure 7 and Figure 11 The first transmission member 45 includes a connecting rod body 451 and a fourth connecting shaft 452 vertically disposed at both ends of the connecting rod body 451. The fourth connecting shaft 452 is used to hinge with the first connecting hole 441 or the second connecting hole 461. Through the relative position change between the connecting member 44 and the door body 12, the first transmission member 45 and the second transmission member 46 are driven to change position relative to the door body.

[0082] In some embodiments of this application, please refer to Figure 2 , Figure 3 , Figure 9 , Figure 11 , Figure 15 and Figure 18 The transmission assembly 4 also includes a second sliding member 47, which is connected to the second transmission member 46. The second sliding member 47 is driven to slide by the rotation of the second transmission member 46. During the closing process of the first door assembly 1, the second sliding member 47 drives the first sliding member 41 to slide towards the flip beam assembly 3, thereby realizing the push and pull of the flip beam assembly 3, and thus realizing the flip of the flip beam body 31.

[0083] It should be noted that the second slider 47 can drive the first slider 41 by directly connecting it to the first slider 41, or it can drive the first slider 41 indirectly by other transmission components (such as the first gear 43). Both methods can achieve the purpose of this application.

[0084] In some embodiments of this application, please refer to Figure 9 and Figure 10The first sliding member 41 and the second sliding member 47 are slidably connected. Both the first sliding member 41 and the second sliding member 47 can slide along the length direction of the first door assembly 1. The second sliding member 47 has a receiving space 471 that matches the first sliding member 41. When the second sliding member 47 indirectly drives the first sliding member 41 through other transmission components, the first sliding member 41 can extend out of or retract into the receiving space 471 to avoid motion interference between the first sliding member 41 and the second sliding member 47.

[0085] In some embodiments of this application, please refer to Figure 5 , Figure 10 , Figure 15 and Figure 18 The first sliding member 41 has a first guide part 412 that matches the second sliding member 47, which can guide the sliding of the second sliding member 47, ensuring the accuracy of the relative movement between the first sliding member 41 and the second sliding member 47, thereby ensuring the stability and reliability of the flip beam drive mechanism.

[0086] In some embodiments of this application, please refer to Figure 9 , Figure 10 , Figure 15 and Figure 18 The second sliding member 47 has a second guide part 472 that matches the first sliding member 41, which can guide the sliding of the first sliding member 41, ensuring the accuracy of the relative movement between the first sliding member 41 and the second sliding member 47, thereby ensuring the stability and reliability of the flip beam drive mechanism.

[0087] It should be noted that the first guide portion 412 and the second guide portion 472 both extend along the sliding direction of the first slider 41 (or the sliding direction of the second slider 47). The first guide portion 412 and the second guide portion 472 can be provided separately or simultaneously. As long as the accuracy of the relative sliding between the first slider 41 and the second slider 47 can be guaranteed, the purpose of this application can be achieved.

[0088] In some embodiments of this application, please refer to Figure 2 , Figure 9 and Figure 16 The second sliding member 47 is provided with a first sliding groove 475 so that the hinge shaft 21 extends from the first sliding groove 475 into the receiving space 471 of the second sliding member 47 and connects with the connector 44 and the door body 12 in sequence. During the sliding process of the first sliding member 41, the presence of the first sliding groove 475 can prevent the hinge shaft 21 from interfering with the sliding of the first sliding member 41.

[0089] In some embodiments of this application, please refer to Figure 9 , Figure 10 and Figure 11 The second sliding member 47 is provided with a second sliding groove 476, which, while cooperating with the rotating shaft part 463 of the second transmission member 46, can prevent the rotating shaft part 463 of the second transmission shaft from interfering with the sliding of the second sliding member 47.

[0090] In some embodiments of this application, please refer to Figure 8 , Figure 9 , Figure 11 , Figure 15 and Figure 18 The second transmission component 46 is a second gear component, and the second sliding component 47 is provided with a second rack portion 473 and a third rack portion 474. The second gear component is meshed with the second rack portion 473. The first rack portion 411 and the third rack portion 474 are arranged opposite to each other and are meshed with each other on both sides of the first gear component 43. The rotation of the second gear component (i.e., the second transmission component 46) pushes the second rack portion 473 and the second sliding component 47 to slide. When the third rack portion 47 slides with the second sliding component 47, it drives the first gear component 43 to rotate. Then, the first gear component 43 meshes with the first rack portion 411 to push the first sliding component 41 to slide. The first sliding component 41 pushes and pulls the tilting beam body 31, thereby realizing the automatic tilting of the tilting beam body 31 during the opening and closing of the door. It has the advantages of smooth transmission, reliability and high accuracy.

[0091] In some embodiments of this application, please refer to Figure 8 , Figure 15 and Figure 18 The second gear component (i.e., the second transmission component 46) is an incomplete gear. The engagement of the incomplete gear with the second rack portion 473 allows for complex motion control within a limited accommodating space 471 (the width of the accommodating space 471 is limited by the thickness of the door body 12). Its compact structure makes it suitable for scenarios with high space requirements. It is suitable for placing the transmission component 4 on the door body 12, providing precise motion control without increasing the volume of the door body 12 and optimizing space utilization. At the same time, since only a portion of the second gear component engages with the second rack portion 473, only a portion of the outer peripheral area of ​​the second gear component needs to have teeth 462. This design allows for high local stress in the meshing area, while the non-meshing area does not bear any load. It can provide sufficient load capacity during the meshing phase, while reducing wear and energy consumption during the non-meshing phase, thus extending the component's lifespan.

[0092] In some embodiments of this application, please refer to Figure 3 , Figure 4 and Figure 11The door body 12 of the first door assembly 1 is provided with a first hinge hole 121, a second hinge hole 122, and a third hinge hole 123. The first hinge hole 121 is used to install a first gear 43, allowing the first gear 43 to rotate relative to the door body 12, thereby engaging with the first rack portion 411 and the third rack portion 474 for transmission. The second hinge hole 122 is used to hinge with the hinge shaft 21 of the hinge assembly 2, allowing the door body 12 to rotate relative to the hinge shaft 21 and the connecting member 44. The third hinge hole 123 is used to hinge with the rotating shaft portion 463 on the second transmission member 46. When the door body 12 rotates relative to the connecting member 44 and changes position, the first transmission member 45, which is hinged to the connecting member 44, drives the second transmission member 46 to rotate relative to the door body 12, thereby achieving the sliding drive of the second sliding member 47, and thus realizing the automatic flipping of the flip beam body 31.

[0093] In some embodiments of this application, please refer to Figure 4 , Figure 11 and Figure 15 The first door assembly 1 is provided with a guide structure 11, which is matched with the first sliding member 41 and / or the second sliding member 47 to ensure that the first sliding member 41 and / or the second sliding member 47 slides in a preset direction, thereby ensuring the accuracy of the operation of the flip beam drive mechanism.

[0094] In some embodiments of this application, please refer to Figure 4 , Figure 11 and Figure 15 When the hinge assembly 2 is connected to the top of the first door assembly 1, the guide structure 11 includes a first guide plate 111 and a second guide plate 112 disposed on the top of the first door assembly 1. The first guide plate 111 and the second guide plate 112 are disposed opposite to each other and both extend along the length direction of the first door assembly 1, thereby forming a groove between the first guide plate 111 and the second guide plate 112 that matches the second sliding member 47. When the second sliding member 47 slides back and forth along the length direction of the first door assembly 1, the first guide plate 111 and the second guide plate 112 can guide the second sliding member 47 to slide. At the same time, due to the presence of the first guide portion 412 and / or the second guide portion 472, the second sliding member 47 can guide the first sliding member 41 to slide, thereby ensuring that both the first sliding member 41 and the second sliding member 47 can slide along a preset direction (i.e., the length direction of the first door assembly 1).

[0095] Please see Figures 1 to 18 The second aspect of this application provides a door assembly, including the tilting beam drive mechanism described in the above embodiments, and further including a second door assembly 5, the second door assembly 5 being located on the rotation side, and the tilting beam assembly 3 being used for sealing contact with the second door assembly 5, such as... Figure 12, Figure 17 and Figure 18 As shown, this can prevent cold air from leaking from the gap between the first door assembly 1 and the second door assembly 5, reducing unnecessary energy waste.

[0096] In some embodiments of this application, please refer to Figures 12 to 18 The hinge assembly 2 is hinged to the top side of the first door assembly 1, and the flip beam assembly 3 is hinged to the side of the first door assembly 1 near the second door assembly 5. At this time, the hinge assembly 2 and the flip beam assembly 3 are located on adjacent sides of the first door assembly 1, which facilitates the arrangement of the transmission assembly 4 on the top of the first door assembly 1 and simplifies the transmission path.

[0097] It should be noted that the first door assembly 1 and the second door assembly 5 are designed as double doors. When opening the door, the second door assembly 5 is opened first, and then the first door assembly 1 is opened. Correspondingly, when closing the door, the first door assembly 1 is closed first, and then the second door assembly 5 is closed. This can prevent the second door assembly 5 from interfering with the flip beam assembly 3 on the first door assembly 1.

[0098] In some embodiments of this application, please refer to Figure 12 and Figure 17 The main body 31 of the tilting beam and / or the second door assembly 5 are provided with sealing elements or magnetic elements to improve the sealing effect between the main body 31 of the tilting beam and the second door assembly 5.

[0099] Please see Figures 1 to 18 The third aspect of this application provides a refrigeration device, including the flip beam drive mechanism described in the above embodiments; or, including the door assembly described in the above embodiments, which can drive the flip beam body 31 to automatically flip through the flip beam drive mechanism, thereby achieving a gap seal between the first door assembly 1 and the door frame or other door (such as the second door assembly 5), preventing cold air leakage and avoiding an increase in the energy consumption of the refrigeration device.

[0100] In some embodiments of this application, the refrigeration device can be a high-end single-door refrigerator, including the flip beam drive mechanism and cabinet 6 described in the above embodiments. The flip beam assembly 3 is used to achieve a sealed contact with the door frame of the cabinet 6, thereby achieving an ultimate sealing effect and user experience.

[0101] In some embodiments of this application, the refrigeration equipment can be a side-by-side refrigerator, a cross-door refrigerator, or a French door refrigerator, etc., including the door assembly described in the above embodiments. The flip beam assembly 3 achieves a sealed contact with the second door assembly 5 to prevent cold air leakage.

[0102] In the above embodiments, since the automatic flipping of the flip beam assembly 3 only needs to be linked by the rotation of the transmission assembly 4 and the first door assembly 1 relative to the hinge assembly 2, there is no need to set guide blocks or other components on the cabinet 6 of the refrigeration equipment. During the opening and closing of the first door assembly 1, the flip beam assembly 3 automatically flips, which is convenient to drive. During the flipping process, there is no problem of high opening and closing resistance and easy noise generation, which can improve the user experience.

[0103] In some embodiments of this application, please refer to Figure 12 and Figure 13 The first door assembly 1 and the second door assembly 5 are both hinged to the cabinet 6 of the refrigeration equipment via the hinge assembly 2. The hinge plate 22 in the hinge assembly 2 is fixedly installed on the cabinet 6 (such as the top). The opening and closing of the refrigeration space inside the cabinet 6 is achieved by rotating the first door assembly 1 and the second door assembly 5 relative to the hinge assembly 2.

[0104] In some embodiments of this application, please refer to Figures 1 to 18 The closing process of the above-mentioned door assembly is as follows:

[0105] Step A1: Push the first door assembly 1 to rotate toward the direction close to the box 6. The connecting piece 44 in the transmission assembly 4 and the hinge shaft 21 maintain a fixed relative position, and the relative position between them and the door body 12 changes.

[0106] Step A2: Because the first transmission component 45 is connected to the connecting component 44, its relative position to the door body 12 also changes, thereby causing the second transmission component 46 to rotate in the forward direction relative to the door body 12 (along...). Figure 15 (rotate counterclockwise);

[0107] Step A3: The second rack portion 473 in the second sliding member 47 engages with the gear tooth portion 462 on the second transmission member 46, and slides away from the tilting beam assembly 3 under the pushing action of the second transmission member 46 (i.e., towards...). Figure 15 (Slide above);

[0108] Step A4: The third rack section 474 moves synchronously (i.e., towards) Figure 15 (sliding upwards), causing the first gear 43 to rotate forward relative to the door body 12 (along...) Figure 15 (rotate counterclockwise);

[0109] Step A5: The first rack portion 411 engages with the first gear component 43 for transmission, and slides towards the direction of approaching the tilting beam assembly 3 (i.e. towards...). Figure 15 (Slide down) to push out the first slider 41;

[0110] Step A6: The first connecting rod 42 changes position under the pushing action of the first sliding member 41, and drives the main body 31 of the tilting beam assembly 3 to tilt in the forward direction (along...). Figure 15 (Flip counterclockwise in the middle), then close the second door assembly 5 to achieve... Figure 17 and Figure 18 The state shown.

[0111] In some embodiments of this application, please refer to Figures 1 to 18 The opening process of the above-mentioned door assembly is as follows:

[0112] Step B1: First rotate the second door assembly 5 in a direction away from the box 6, then rotate the first door assembly 1 in a direction away from the box 6.

[0113] Step B2: During the rotation of the first door assembly 1, the connecting piece 44 in the transmission assembly 4 maintains a fixed relative position with the hinge shaft 21, and undergoes a relative position change with the door body 12;

[0114] Step B3: Because the first transmission component 45 is connected to the connecting component 44, its relative position to the door body 12 also changes, thereby causing the second transmission component 46 to rotate in the opposite direction relative to the door body 12 (along...). Figure 18 (rotate clockwise);

[0115] Step B4: The second rack portion 473 in the second sliding member 47 slides towards the direction of the tilting beam assembly 3 under the pushing action of the second transmission member 46 (i.e., towards...). Figure 18 (Slide to the right);

[0116] Step B5: The third rack section 474 moves synchronously (i.e., towards) Figure 18 (sliding to the right), causing the first gear 43 to rotate in the opposite direction relative to the door body 12 (along the right side). Figure 18 (rotate clockwise);

[0117] Step B6: The first rack portion 411 meshes with the first gear component 43, and slides away from the tilting beam assembly 3 (i.e., towards...). Figure 18 (Slide to the left) to retract the first slider 41;

[0118] Step B7: The first connecting rod 42 changes position under the pushing action of the first sliding member 41, and drives the main body 31 of the tilting beam assembly 3 to tilt in the opposite direction (along...). Figure 18 (flip clockwise) to achieve Figure 14 and Figure 15 The state shown.
