In order to prevent cold air from leaking through the gap between the left and right refrigerator doors, a turning beam is often provided on one of the refrigerator doors. When the refrigerator door is closed, the turning beam can be turned to the unfolded state, so as to closely fit the door frame or the other door, effectively sealing the gap and preventing cold air from leaking.

[0061] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0062] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0063] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may 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 herein are interpreted accordingly.

[0064] In order to solve the technical problems in the prior art that when the flip beam is automatically flipped by a guide block, there is a large switching resistance and noise is easily generated, the present application provides a flip beam driving mechanism, which does not need to set a guide block on the refrigerator body 6, and is respectively connected to the hinge assembly 2 and the flip beam assembly 3 through the transmission assembly 4. The transmission assembly 4 and the flip beam assembly 3 can be driven by the position change of the first door body assembly 1 relative to the hinge assembly 2, and the automatic flipping of the flip beam assembly 3 during the opening and closing process of the first door body assembly 1 can be achieved, and the large switching resistance and noise caused by the setting of the guide block can be avoided.

[0065] See alsoFigures 1 to 18 , in the first aspect of the embodiment of the present application, a flip beam driving mechanism is provided, which includes a first door body assembly 1, a hinge assembly 2, a flip beam assembly 3 and a transmission assembly 4. The first door body assembly 1 includes an installation side and a rotation side that are opposite in position. The hinge assembly 2 is arranged on the installation side and is rotatably connected to the first door body assembly 1, so that the first door body assembly 1 can rotate relative to the hinge assembly 2, thereby realizing the switching between the open state and the closed state, as Figure 1 , Figure 13 and Figure 16 shown.

[0066] The flip beam assembly 3 is arranged on the rotation side and is rotatably connected to one side of the first door body assembly 1. When the first door body assembly 1 is in the open state and the closed state respectively, the flip positions of the flip beam assembly 3 relative to the first door body assembly 1 are different, as Figure 14 , Figure 15 , Figure 17 and Figure 18 shown, where Figure 15 and Figure 18 the dotted line positions in are the sealing positions of the flip beam assembly 3 (that is, the positions where the flip beam assembly 3 flips to the unfolded state for sealing abutment), Figure 15 the arrow direction in is the flipping direction (that is, the rotation direction) of the flip beam assembly 3. Specifically, when the first door body assembly 1 is in the open state, the flip beam assembly 3 flips to a state where it fits against the side edge of the first door body assembly 1 (hereinafter referred to as the fitting state), as Figure 14 and Figure 15 shown; when the first door body assembly 1 is in the closed state, the flip beam assembly 3 flips to the unfolded state, as Figure 17 and Figure 18 shown, so that the flip beam assembly 3 can achieve the effect of gap blocking.

[0067] The transmission assembly 4 is arranged on the first door body assembly 1. The transmission assembly 4 is respectively in transmission connection with the hinge assembly 2 and the flip beam assembly 3, and is used to make the flip beam assembly 3 flip as the first door body assembly 1 rotates relative to the hinge assembly 2. By changing the relative position between the first door body assembly 1 and the hinge assembly 2, the components in the transmission assembly 4 are driven 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 body assembly 1.

[0068] It should be noted that the flipping of the flip beam assembly 3 of the present application does not need to be realized through a guide block, which can avoid problems such as large switching resistance and easy generation of noise when the flip beam cooperates with the guide block, and is beneficial to improving the user experience.

[0069] In the above embodiments, the transmission assembly 4 may include a link assembly, a gear assembly, a synchronous belt assembly, etc. As long as the flipping of the flipping beam assembly 3 and the rotation of the first door body assembly 1 can be linked, the purpose of the present application can be achieved.

[0070] In some embodiments of the present application, please refer to Figure 1 , Figure 2 and Figure 10 , the transmission assembly 4 includes a first sliding member 41 and a first link 42. The first sliding member 41 is slidably disposed on the first door body assembly 1. The first link 42 is respectively hinged to the first sliding member 41 and the flipping beam assembly 3, and the first sliding member 41, the first link 42 and the flipping beam assembly 3 can be connected into a three-link structure. During the closing process of the first door body assembly 1, the first sliding member 41 drives the first link 42 to push the flipping beam assembly 3 to flip to the unfolded state, so that after the flipping beam assembly 3 flips to the inner side of the first door body assembly 1 (the inner side is the side close to the cabinet 6), the gap between the first door body assembly 1 and other door bodies or door frames can be sealed.

[0071] Specifically, while the first door body assembly 1 rotates relative to the hinge assembly 2, the sliding drive of the first sliding member 41 is realized. The sliding drive method can be indirectly transmitted through other components, or the first sliding member 41 can be directly abutted against the hinge assembly 2, and the sliding drive of the first sliding member 41 is realized through the relative position change between the hinge assembly 2 and the first sliding member 41. Then, the sliding of the first sliding member 41 drives the position of the first link 42 to change, and the first link 42 pushes or pulls the flipping beam assembly 3 to flip.

[0072] In some embodiments of the present application, please refer to Figure 2 and Figure 10 , the flipping beam assembly 3 includes a flipping beam main body 31 and a hinge seat 32. The hinge seat 32 is fixedly disposed on the first door body assembly 1, and the flipping beam main body 31 is hinged to the hinge seat 32, so that the flipping beam main body 31 can flip relative to the first door body assembly 1. A first connecting shaft 311 for hinging with the first link 42 is provided on the flipping beam main body 31, and a third connecting shaft 413 for hinging with the first link 42 is provided at one end of the first sliding member 41 close to the flipping beam main body 31. When the first sliding member 41 slides along the length direction of the first door body assembly 1 (i.e., the left-right direction in Figure 2 ), the flipping beam main body 31 can be pushed and pulled by the first link 42, so as to realize the flipping of the flipping beam main body 31 relative to the first door body assembly 1.

[0073] In some embodiments of the present application, please refer to Figure 3 and Figure 10, one or more hinge seats 32 are provided in the height direction of the first door body assembly 1 for stably connecting with the main body 31 of the flipping beam. The hinge seat 32 includes a seat body 321 and a second connecting shaft 322. A groove matching with the hinge seat 32 is provided on the main body 31 of the flipping beam, and a fourth hinge hole 312 for hinging with the second connecting shaft 322 is provided on the side wall of the groove, so as to facilitate the flipping of the main body 31 of the flipping beam relative to the hinge seat 32.

[0074] In some embodiments of the present application, please refer to Figure 2 , Figure 3 and Figure 11 , a first rack portion 411 is provided on the first sliding member 41. The first rack portion 411 extends along the sliding direction of the first sliding member 41 and can be used to realize the sliding drive of the first sliding member 41. The transmission assembly 4 further includes a first gear member 43 rotatably provided on the first door body assembly 1. During the closing process of the first door body assembly 1, the first gear member 43 rotates forward; during the opening process of the first door body assembly 1, the first gear member 43 rotates reversely. The first gear member 43 is meshed and connected with the first rack portion 411, and the first gear member 43 rotates to drive the first rack portion 411 to slide. When the first gear member 43 rotates forward, it pushes the first rack portion 411 and the first sliding member 41 towards the flipping beam assembly 3, so that the main body 31 of the flipping beam is flipped to the unfolded state; when the first gear member 43 rotates reversely, it pushes the first rack portion 411 and the first sliding member 41 away from the flipping beam assembly 3, so that the main body 31 of the flipping beam is flipped to the fitting state.

[0075] It should be noted that, in order to realize the rotational drive of the first gear member 43 through the opening and closing of the first door body assembly 1, mechanisms such as linkages, gear racks, and cams can be used to convert the displacement / angle change of the first door body assembly 1 relative to the hinge assembly 2 into torque output. As long as the rotational drive of the first gear member 43 can be realized, the purpose of the present application can be achieved.

[0076] In some embodiments of the present application, please refer to Figure 3 , Figure 6 , Figure 7 and Figure 11, the transmission assembly 4 further includes a connecting member 44, a first transmission member 45 and a second transmission member 46. The connecting member 44 is fixedly connected to the hinge shaft 21 of the hinge assembly 2. When the first door body assembly 1 rotates relative to the hinge shaft 21, the relative position between the connecting member 44 and the first door body assembly 1 also changes; the first transmission member 45 and the second transmission member 46 are both movably arranged on the first door body assembly 1, and the first transmission member 45 is respectively connected to the connecting member 44 and the second transmission member 46. When the position of the first door body assembly 1 changes relative to the hinge shaft 21 and the connecting member 44, the positions of the first transmission member 45 and the second transmission member 46 connected to the connecting member 44 relative to the first door body assembly 1 also change, as Figure 15 and Figure 18 shown. During the closing process of the first door body assembly 1, the second transmission member 46 drives the first sliding member 41 to slide, so as to realize the pushing and pulling of the first sliding member 41 on the flipping beam assembly 3, and further realize the flipping of the flipping beam main body 31 in the flipping beam assembly 3.

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

[0078] In some embodiments of the present application, please refer to Figure 3 , Figure 11 , Figure 14 , Figure 15 , Figure 17 and Figure 18 , the first transmission member 45 is a second connecting rod. The second connecting rod is respectively hinged to the connecting member 44 and the second transmission member 46 to form a three-link structure, so as to drive the second transmission member 46 to rotate relative to the first door body assembly 1, and thus drive 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 meshing with the first rack portion 411 on the first sliding member 41, or can also realize indirect transmission by arranging other transmission components between the second transmission member 46 and the first sliding member 41, and the purpose of the present application can be achieved.

[0080] In some embodiments of the present application, please refer toFigure 6 , Figure 8 , Figure 11 , Figure 14 , Figure 15 , Figure 17 and Figure 18 , the connecting member 44 has an eccentrically arranged first connecting hole 441, the second transmission member 46 has an eccentrically arranged second connecting hole 461, and both ends of the second connecting rod are respectively hinged to the first connecting hole 441 and the second connecting hole 461, so that an eccentricity can be formed between both ends of the second connecting rod and the rotation axes of the first door body assembly 1 and 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 connecting member 44 can be accurately controlled, thereby realizing the accurate driving of the first sliding member 41.

[0081] In some embodiments of the present application, please refer to Figure 7 and Figure 11 , the first transmission member 45 includes a connecting rod body 451 and fourth connecting shafts 452 vertically arranged at both ends of the connecting rod body 451. The fourth connecting shafts 452 are used for being hinged to the first connecting hole 441 or the second connecting hole 461. Through the relative position change between the connecting member 44 and the door main body 12, the first transmission member 45 and the second transmission member 46 are driven to change their positions relative to the door main body.

[0082] In some embodiments of the present application, please refer to Figure 2 , Figure 3 , Figure 9 , Figure 11 , Figure 15 and Figure 18 , the transmission assembly 4 further includes a second sliding member 47. The second transmission member 46 is in transmission connection with the second sliding member 47. 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 body assembly 1, the second sliding member 47 drives the first sliding member 41 to slide towards the turning beam assembly 3, thereby realizing the pushing and pulling of the turning beam assembly 3, and further realizing the turning of the turning beam main body 31.

[0083] It should be noted that the second sliding member 47 can directly drive the first sliding member 41 to slide by connecting with the first sliding member 41, or can indirectly drive the first sliding member 41 through other transmission components (such as the first gear member 43, etc.), and both can achieve the purpose of the present application.

[0084] In some embodiments of the present application, please refer to Figure 9 and Figure 10, the first sliding member 41 is slidably connected to the second sliding member 47. Both the first sliding member 41 and the second sliding member 47 can slide along the length direction of the first door body assembly 1. The second sliding member 47 has a receiving space 471 that is arranged to match 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, avoiding movement interference between the first sliding member 41 and the second sliding member 47.

[0085] In some embodiments of the present application, please refer to Figure 5 , Figure 10 , Figure 15 and Figure 18 , the first sliding member 41 is provided with a first guiding portion 412 that is arranged to match the second sliding member 47, which can achieve sliding guidance for the second sliding member 47, ensuring the accuracy of the relative movement between the first sliding member 41 and the second sliding member 47, and thus ensuring the stability and reliability of the turning beam driving mechanism.

[0086] In some embodiments of the present application, please refer to Figure 9 , Figure 10 , Figure 15 and Figure 18 , the second sliding member 47 is provided with a second guiding portion 472 that is arranged to match the first sliding member 41, which can achieve sliding guidance for the first sliding member 41, ensuring the accuracy of the relative movement between the first sliding member 41 and the second sliding member 47, and thus ensuring the stability and reliability of the turning beam driving mechanism.

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

[0088] In some embodiments of the present 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 into the receiving space 471 of the second sliding member 47 from the first sliding groove 475 and is sequentially connected to the connecting member 44 and the door main body 12. During the sliding process of the first sliding member 41, the existence 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 the present application, please refer to Figure 9 , Figure 10 andFigure 11 A second sliding member 47 is provided with a second sliding groove 476. While cooperating with the rotating shaft portion 463 of the second transmission member 46, it can prevent the rotating shaft portion 463 of the second transmission shaft from interfering with the sliding of the second sliding member 47.

[0090] In some embodiments of the present application, please refer to Figure 8 、 Figure 9 、 Figure 11 、 Figure 15 and Figure 18 The second transmission member 46 is a second gear member. The second sliding member 47 is provided with a second rack portion 473 and a third rack portion 474. The second gear member is meshed and connected with the second rack portion 473. The first rack portion 411 and the third rack portion 474 are oppositely arranged and are respectively meshed and connected to both sides of the first gear member 43. By the rotation of the second gear member (i.e., the second transmission member 46) to push the second rack portion 473 and the second sliding member 47 to slide, when the third rack portion 474 slides with the second sliding member 47, it drives the first gear member 43 to rotate, and then through the meshing of the first gear member 43 and the first rack portion 411 to push the first sliding member 41 to slide, and the first sliding member 41 realizes pushing and pulling on the turning beam main body 31, so as to realize the automatic turning of the turning beam main body 31 during the process of opening and closing the door, having the advantages of stable, reliable and high-precision transmission.

[0091] In some embodiments of the present application, please refer to Figure 8 、 Figure 15 and Figure 18 The second gear member (i.e., the second transmission member 46) is an incomplete gear. The cooperation between the incomplete gear and the second rack portion 473 allows for the realization of complex motion control within a limited accommodation space 471 (the width of the accommodation space 471 is limited by the thickness of the door main body 12). Its structure is compact, suitable for scenarios with high space requirements, suitable for arranging the transmission assembly 4 on the door main body 12, and can provide precise motion control without increasing the volume of the door main body 12, optimizing the space utilization rate. At the same time, since only a partial area of the second gear member cooperates with the second rack portion 473, only a tooth portion 462 needs to be provided on a partial outer peripheral area of the second gear member. This design allows for a higher local stress to be borne in the meshing area, while not bearing load in the non-meshing area, can provide sufficient load capacity during the meshing stage, and can reduce wear and energy consumption during the non-meshing stage, extending the service life of the components.

[0092] In some embodiments of the present application, please refer to Figure 3 、 Figure 4 and Figure 11, on the door main body 12 of the first door body assembly 1, there are provided a first hinge hole 121, a second hinge hole 122 and a third hinge hole 123. Among them, the first hinge hole 121 is used to install the first gear member 43, so that the first gear member 43 can rotate relative to the door main body 12, and thus engage and drive with the first rack portion 411 and the third rack portion 474. The second hinge hole 122 is used to be hinged with the hinge shaft 21 of the hinge assembly 2, so that the door main body 12 can rotate relative to the hinge shaft 21 and the connecting member 44; the third hinge hole 123 is used to be hinged with the rotating shaft portion 463 on the second transmission member 46. When the door main body 12 rotates relative to the connecting member 44 to cause a position change, the first transmission member 45 hinged with the connecting member 44 drives the second transmission member 46 to rotate relative to the door main body 12, thereby realizing the sliding drive of the second sliding member 47, and further realizing the automatic flipping of the flipping beam main body 31.

[0093] In some embodiments of the present application, please refer to Figure 4 , Figure 11 and Figure 15 , a guiding structure 11 is provided on the first door body assembly 1. The guiding structure 11 is arranged in a matching manner with the first sliding member 41 and / or the second sliding member 47, ensuring that the first sliding member 41 and / or the second sliding member 47 slide along a preset direction, thereby ensuring the action accuracy of the flipping beam driving mechanism.

[0094] In some embodiments of the present 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 body assembly 1, the guiding structure 11 includes a first guiding plate 111 and a second guiding plate 112 arranged on the top of the first door body assembly 1, and the first guiding plate 111 and the second guiding plate 112 are arranged oppositely and both extend along the length direction of the first door body assembly 1, thereby forming a chute matching with the second sliding member 47 between the first guiding plate 111 and the second guiding plate 112. When the second sliding member 47 reciprocally slides along the length direction of the first door body assembly 1, the sliding guiding of the second sliding member 47 can be realized through the first guiding plate 111 and the second guiding plate 112. At the same time, due to the existence of the first guiding portion 412 and / or the second guiding portion 472, the sliding guiding of the first sliding member 41 can be realized through the second sliding member 47, so as to ensure that both the first sliding member 41 and the second sliding member 47 can slide along the preset direction (i.e., the length direction of the first door body assembly 1).

[0095] Please refer to Figures 1 to 18 , the second aspect of the embodiments of the present application provides a door body assembly, including the flipping beam driving mechanism described in the above embodiments, and further including a second door body assembly 5. The second door body assembly 5 is located on the rotating side, and the flipping beam assembly 3 is used to be in sealing contact with the second door body assembly 5, as Figure 12, Figure 17 and Figure 18 As shown in Figure 17 and Figure 18 , it is possible to prevent cold air from leaking through the gap between the first door body assembly 1 and the second door body assembly 5, reducing unnecessary energy waste.

[0096] In some embodiments of the present application, please refer to Figures 12 to 18 . The hinge assembly 2 is hinged to the top side of the first door body assembly 1, and the flip beam assembly 3 is hinged to the side of the first door body assembly 1 close to the second door body assembly 5. At this time, the hinge assembly 2 and the flip beam assembly 3 are respectively located on two adjacent sides of the first door body assembly 1, which can facilitate the layout of the transmission assembly 4 on the top of the first door body assembly 1 and simplify the transmission path.

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

[0098] In some embodiments of the present application, please refer to Figure 12 and Figure 17 . A seal or magnetic attraction member is provided on the flip beam main body 31 and / or the second door body assembly 5 to enhance the sealing effect between the flip beam main body 31 and the second door body assembly 5.

[0099] Please refer to Figures 1 to 18 . In the third aspect of the embodiments of the present application, a refrigeration device is provided, which includes the flip beam driving mechanism described in the above embodiments; or, it includes the door body assembly described in the above embodiments.

The flip beam assembly 3 is used to achieve a sealed abutment with the second door body assembly 5 to prevent cold air leakage.

[0102] In the above embodiments, since the automatic flipping of the flipping beam assembly 3 only needs to be interlocked through the rotation of the transmission assembly 4 and the first door body assembly 1 relative to the hinge assembly 2, and there is no need to provide components such as guide blocks on the box body 6 of the refrigeration device. During the process of opening and closing the first door body assembly 1, the flipping beam assembly 3 automatically flips, which is convenient to drive. During the flipping process of the flipping beam assembly 3, there will be no problems of large switching resistance and easy generation of noise, and the user experience can be improved.

[0103] In some embodiments of the present application, please refer to Figure 12 and Figure 13 , the first door body assembly 1 and the second door body assembly 5 are both hinged to the box body 6 of the refrigeration device through the hinge assembly 2. The hinge plate 22 in the hinge assembly 2 is fixedly arranged on the box body 6 (such as the top), and the opening and closing of the refrigerated space inside the box body 6 is realized by the rotation of the first door body assembly 1 and the second door body assembly 5 relative to the hinge assembly 2.

[0106] Step A2: Since the first transmission member 45 is connected to the connecting piece 44, the relative position between it and the door main body 12 also changes, and then drives the second transmission member 46 to rotate positively relative to the door main body 12 (rotating counterclockwise along Figure 15 );

[0107] Step A3: The second rack portion 473 in the second sliding member 47 meshes with the tooth portion 462 on the second transmission member 46, and slides away from the flipping beam assembly 3 under the pushing action of the second transmission member 46 (that is, slides upward towards Figure 15 );

[0108] Step A4: The third rack portion 474 moves synchronously accordingly (that is, slides upward towards Figure 15 ), driving the first gear member 43 to rotate positively relative to the door main body 12 (rotating counterclockwise along Figure 15 );

[0109] Step A5: The first rack portion 411 meshes with the first gear member 43 and slides towards the direction close to the flipping beam assembly 3 (that is, slides downward towards Figure 15 ), pushing out the first sliding member 41;

[0110] Step A6: The first link 42 changes its position under the pushing action of the first slider 41, and drives the main body 31 of the turning beam in the turning beam assembly 3 to turn forward (rotate counterclockwise along Figure 15 ), then closes the second door assembly 5 to reach the state shown in Figure 17 and Figure 18 .

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

[0112] Step B1: First, rotate the second door assembly 5 away from the box body 6, and then rotate the first door assembly 1 away from the box body 6;

[0113] Step B2: During the rotation of the first door assembly 1, the connecting member 44 in the transmission assembly 4 keeps the relative position fixed with the hinge shaft 21, and the relative position changes with the door main body 12;

[0114] Step B3: Since the first transmission member 45 is connected to the connecting member 44, the relative position between it and the door main body 12 also changes, thereby driving the second transmission member 46 to rotate in the opposite direction relative to the door main body 12 (rotate clockwise along Figure 18 );

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

[0116] Step B5: The third rack portion 474 moves synchronously accordingly (i.e., slides towards the right side of Figure 18 ), driving the first gear member 43 to rotate in the opposite direction relative to the door main body 12 (rotate clockwise along Figure 18 );

[0117] Step B6: The first rack portion 411 meshes with the first gear member 43 and slides away from the turning beam assembly 3 (i.e., slides towards the left side of Figure 18 ), retracting the first slider 41;

[0118] Step B7: The first link 42 changes its position under the pushing action of the first slider 41, and drives the main body 31 of the turning beam in the turning beam assembly 3 to turn in the opposite direction (rotate clockwise along Figure 18 ), reaching the state shown in Figure 14 and Figure 15 .
