Most refrigerators on the market are single-door or double-door refrigerators with limited capacity. When the refrigerator door is opened, a large amount of cold air is lost, resulting in low refrigerator efficiency. Therefore, door-in-door refrigerators have emerged. When the items to be stored are large, users can open the main door to store the items. When the items to be stored are small, users can only open the secondary door to store the items, thereby reducing the loss of cold air.
[0003] Current door-in-door refrigerators are equipped with a door lock on the secondary door to lock the secondary door to the main door so that the secondary door can move with the main door to prevent the secondary door from being opened while the user is opening the main door.
[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:
[0005] Existing door-in-door refrigerators generally have a door lock with a lock hook and other structures on the secondary door, and the secondary door can be locked to the main door through the lock hook. This will increase the thickness of the secondary door body and affect the aesthetics.
[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0047] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.
[0048] The disclosed embodiment provides a door assembly 02 and a refrigeration device, which can lock or unlock the auxiliary door 20 to or from the main door 10 by locking or unlocking the hinge shaft 212, without the need to separately set up a lock hook or other structure. In this way, the thickness of the auxiliary door 20 can be reduced, thereby improving the overall aesthetics of the refrigeration device.
[0049] like Figures 1 to 8 As shown, the embodiment of the present disclosure provides a door body assembly 02 including a main door 10, a secondary door 20, a secondary door hinge 21, a locking structure and a transmission device. The main door 10 is provided with an opening. The secondary door 20 is arranged at a position corresponding to the opening of the main door 10, and includes a door handle 22 provided with a pressing piece 24. The secondary door hinge 21 includes a hinge plate 211 fixedly arranged on the main door 10 and a hinge shaft 212 inserted in the secondary door 20. The locking structure is arranged at a position corresponding to the hinge shaft 212 of the secondary door 20, and can lock or unlock the hinge shaft 212. The pressing piece 24 is connected to the locking structure through the transmission device. Among them, the pressing piece 24 can be rotated in a first direction to control the locking device to lock the hinge shaft 212, at which time the secondary door 20 is locked to the main door 10, or the pressing piece 24 can be rotated in a second direction to control the locking device to unlock the hinge shaft 212, at which time the secondary door 20 is unlocked to the main door 10.
[0050] Specifically, the door assembly 02 can be applied to a refrigeration device, and the main door 10 is rotatably arranged on the box body 01 of the refrigeration device through the main door hinge. The auxiliary door 20 is provided with an axis hole, and a shaft sleeve 213 is arranged in the axis hole. The hinge plate 211 of the auxiliary door hinge 21 is fixedly arranged on the main door 10, and the hinge shaft 212 of the auxiliary door hinge 21 is inserted into the shaft sleeve 213 of the auxiliary door 20. Among them, the hinge shaft 212 can rotate relative to the shaft sleeve 213. The auxiliary door 20 can rotate around the hinge shaft 212 to open or close the opening of the main door 10. The user can lock the auxiliary door 20 to the main door 10 through the locking structure to prevent the auxiliary door 20 from rotating around the hinge shaft 212. With such a configuration, there is no need to set a door lock with a lock hook or other structure, which can reduce the thickness of the door body of the auxiliary door 20, thereby improving the aesthetics.
[0051] If the user needs to store larger items, the pressing plate 24 can be pushed to rotate in the first direction, so that the pressing plate 24 drives the locking structure to lock the hinge shaft 212 of the auxiliary door hinge 21. Figure 8 At this time, the auxiliary door 20 is locked to the main door 10, that is, the auxiliary door 20 cannot rotate relative to the main door 10, so that the user can pull the auxiliary door 20 and the main door 10 to rotate synchronously through the door handle 22 to open the refrigeration device.
[0052] If the user needs to store items of smaller size, the user can pull the pressing piece 24 to rotate in the second direction, so that the pressing piece 24 drives the locking structure to unlock the hinge shaft 212 of the auxiliary door hinge 21. Figure 7 At this time, the auxiliary door 20 is unlocked from the main door 10, that is, the auxiliary door 20 can rotate relative to the main door 10, so that the user can pull the auxiliary door 20 by the door handle 22 to rotate alone to open the refrigeration device. This arrangement can reduce the amount of cold air leakage of the refrigeration device.
[0053] like Figure 5 As shown, optionally, the transmission device is arranged in the auxiliary door 20 to further improve the aesthetics.
[0054] like Figure 1 and Figure 2 As shown, optionally, the main door hinge and the auxiliary door hinge 21 are arranged at the top of the door body assembly 02. Such arrangement can further improve the aesthetics.
[0055] like Figure 7 and Figure 8 As shown, in some embodiments, the locking structure includes a first clamping rod 61 and a second clamping rod 62, and the first clamping rod 61 and the second clamping rod 62 are relatively arranged on both sides of the hinge shaft 212. The first clamping rod 61 and the second clamping rod 62 can move toward the direction close to the hinge shaft 212 to clamp the hinge shaft 212, or the first clamping rod 61 and the second clamping rod 62 can move in the opposite direction away from the hinge shaft 212 to release the hinge shaft 212.
[0056] Specifically, two sides of the end of the hinge shaft 212 inserted into the auxiliary door 20 are provided with planes to form a stop surface 214, such as Figure 8 When the secondary door 20 is buckled into the opening of the primary door 10 , the first clamping rod 61 and the second clamping rod 62 are located at positions corresponding to the stop surface 214 .
[0057] like Figure 8 As shown, the pressing piece 24 can rotate in the first direction to drive the first clamping rod 61 and the second clamping rod 62 to move toward the direction close to the hinge shaft 212 through the transmission device. At this time, the first clamping rod 61 and the second clamping rod 62 can clamp the stop surface 214 from both sides of the hinge shaft 212 to lock the hinge shaft 212 and prevent the auxiliary door 20 from rotating relative to the hinge shaft 212.
[0058] like Figure 7 As shown, the pressing piece 24 can also rotate in the second direction to drive the first clamping rod 61 and the second clamping rod 62 to move away from the hinge shaft 212 through the transmission device. At this time, the first clamping rod 61 and the second clamping rod 62 are separated from the stop surfaces 214 on both sides of the hinge shaft 212 to unlock the hinge shaft 212, so that the auxiliary door 20 can rotate relative to the hinge shaft 212.
[0059] Such an arrangement can improve the stability when the first clamping rod 61 and the second clamping rod 62 clamp the hinge shaft 212 .
[0060] like Figure 3 and Figure 6 As shown, in some embodiments, the transmission device includes a first cylinder 30, a second cylinder 40 and a plunger 32. The first cylinder 30 is provided with a first cavity 31 for storing a transmission medium. The second cylinder 40 is provided with a second cavity 41 connected to the first cavity 31, and the first ends of the first clamping rod 61 and the second clamping rod 62 are inserted in the second cavity 41. The plunger 32 includes a first end inserted in the first cavity 31 and a second end connected to the pressing plate 24. The pressing plate 24 can drive the plunger 32 to reciprocate in the first cavity 31 to extract the transmission medium from the second cavity 41 or push the transmission medium into the second cavity 41, thereby driving the first clamping rod 61 and the second clamping rod 62 to clamp or release the hinge shaft 212.
[0061] Specifically, a first liquid inlet is provided on one end surface of the first cylinder 30, and the transmission medium can flow out of the first cavity 31 or flow into the first cavity 31 through the first liquid inlet. The first end of the plunger 32 is inserted into the first cavity 31 from the other end surface of the first cylinder 30, and the first end of the plunger 32 and the first cylinder 30 are provided with a sealing structure corresponding to the first cavity 31 to separate the first cavity 31. A second liquid inlet is provided on the side wall surface of the second cylinder 40, and the transmission medium can flow into the second cavity 41 or flow out of the second cavity 41 through the second liquid inlet. The first clamping rod 61 and the second clamping rod 62 are relatively arranged on both sides of the second liquid inlet, and the first end of the first clamping rod 61 and the first end of the second clamping rod 62 are respectively provided with a sealing structure corresponding to the second cylinder 40 to separate the second cavity 41. If the plunger 32 moves in a direction away from the first liquid inlet, the atmospheric pressure will draw the transmission medium from the second cavity 41 into the first cavity 31. At this time, the atmospheric pressure will also drive the first clamping rod 61 and the second clamping rod 62 to move in the direction close to the hinge shaft 212, until the first clamping rod 61 and the second clamping rod 62 clamp the hinge shaft 212 to lock the auxiliary door 20 to the main door 10. If the plunger 32 moves in the direction close to the first liquid inlet, the first end of the plunger 32 can push the transmission medium into the second cavity 41. At this time, the transmission medium in the second cavity 41 will also push the first clamping rod 61 and the second clamping rod 62 to move in the direction away from the hinge shaft 212, so that the first clamping rod 61 and the second clamping rod 62 release the hinge shaft 212 and then unlock the auxiliary door 20 to the main door 10.
[0062] like Figures 3 to 6As shown, in some embodiments, the door assembly 02 further includes a swinging push rod 35. The swinging push rod 35 is rotatably disposed on the auxiliary door 20, and includes a first rod body 351 that is transmission-connected to the pressing plate 24 and a second rod body 352 that abuts against the second end of the plunger 32. The pressing plate 24 can drive the second rod body 352 to rotate through the first rod body 351, so that the second rod body 352 pushes the plunger 32 to move in a direction close to the first cylinder body 30.
[0063] Specifically, a fixed base 34 is further provided in the auxiliary door 20, and the fixed base 34 is provided below the second end of the plunger 32, and a rotating shaft 341 is provided on the side of the fixed base 34 facing the plunger 32. The swinging push rod 35 is provided in the rotating shaft 341, and can rotate circumferentially in the rotating shaft 341. The first rod body 351 and the second rod body 352 are relatively provided at the two ends of the swinging push rod 35, and the first rod body 351 is transmission-connected with the pressing plate 24, and the second rod body 352 is abutted against the second end of the plunger 32. The first cylinder body 30 is vertically arranged, and the first liquid inlet is located above the plunger 32. The pressing plate 24 can rotate in the first direction to drive the swinging push rod 35 to rotate in the third direction, thereby disengaging the second rod body 352 from the second end of the plunger 32. At this time, the plunger 32 moves away from the first liquid inlet under the action of gravity, so that the first clamping rod 61 and the second clamping rod 62 clamp the hinge shaft 212, thereby locking the auxiliary door 20 to the main door 10. The pressing piece 24 can also rotate in the second direction to drive the swing push rod 35 to rotate in the fourth direction, thereby causing the second rod body 352 to abut against the plunger 32 and push the plunger 32 to move in the direction close to the first liquid inlet. At this time, the first clamping rod 61 and the second clamping rod 62 release the hinge shaft 212 to unlock the auxiliary door 20 from the main door 10.
[0064] like Figure 4 As shown, optionally, the position where the second rod body 352 abuts against the plunger 32 is set as a ball head structure. Such a setting can improve the smoothness of the second rod body 352 pushing the plunger 32 to move.
[0065] like Figure 3 and Figure 6 As shown, in some embodiments, a tray 33 is provided at the second end of the plunger 32. The door assembly 02 further includes an elastic element 70. The two ends of the elastic element 70 are respectively connected to the first cylinder 30 and the tray 33, and can push the plunger 32 to move away from the first cylinder 30.
[0066] Specifically, the elastic element 70 is a compression spring, and the elastic element 70 is sleeved on the portion of the plunger 32 located outside the first cylinder 30. Both ends of the elastic element 70 are respectively connected to the first cylinder 30 and the tray 33. When the swing push rod 35 is separated from the plunger 32, the elastic element 70 can push the plunger 32 away from the first cylinder 30, so that the first clamping rod 61 and the second clamping rod 62 clamp the hinge shaft 212.
[0067] like Figure 4 As shown, in some embodiments, the swinging top rod 35 is disposed below the tray 33, and the second rod body 352 abuts against the tray 33. The second rod body 352 and the first rod body 351 are disposed in a staggered manner.
[0068] Specifically, the fixed base 34 is disposed below the tray 33, and there is a preset angle between the projection of the first rod 351 on the plane where the second rod 352 is located and the second rod 352 so that the first rod 351 and the second rod 352 are staggered. In this way, during the rotation of the swinging push rod 35, the first rod 351 and the tray 33 can be prevented from interfering with each other while ensuring that the second rod 352 pushes the plunger 32 to move.
[0069] Optionally, the angle between the projection of the first rod 351 on the plane where the second rod 352 is located and the second rod 352 can be set according to the actual needs of the user. For example, the angle between the projection of the first rod 351 on the plane where the second rod 352 is located and the second rod 352 is 90°.
[0070] Optionally, a lower end surface of the swinging top rod 35 is provided with an avoidance opening, which can further prevent the tray 33 and the first rod body 351 from interfering with each other during the rotation of the swinging top rod 35 .
[0071] In some embodiments, the transmission medium is in liquid or gaseous state.
[0072] Specifically, liquid transmission media such as hydraulic oil have the advantages of small inertia, compact structure and flexible layout. Gaseous transmission media have the advantages of green environmental protection, fast response and simple maintenance. Users can choose to use liquid transmission media or gaseous transmission media according to actual needs.
[0073] like Figure 5 As shown, in some embodiments, the transmission device further includes a pipeline 50. The pipeline 50 is arranged in the auxiliary door 20, and is used to connect the first cylinder body 30 and the second cylinder body 40. The pipeline 50 is arranged along the edge of the auxiliary door 20.
[0074] Specifically, both ends of the pipeline 50 are respectively connected to the first liquid inlet and the second liquid inlet, so that the first cylinder 30 is connected to the second rod 352. The transmission medium can flow from the first cylinder 30 to the second cylinder 40 or from the second cylinder 40 to the first cylinder 30 through the pipeline 50. A pipeline groove is provided in the auxiliary door 20, and the pipeline groove is provided along the edge of the auxiliary door 20, and the pipeline 50 is provided in the pipeline groove. In this way, it is more convenient to install the pipeline 50 in the auxiliary door 20.
[0075] like Figure 2 and Figure 3As shown, in some embodiments, the door handle 22 further includes a handle body 23. The handle body 23 is disposed on the outer side of the auxiliary door 20. The pressing piece 24 is rotatably disposed on the handle body 23, and the pressing piece 24 is located between the handle body 23 and the auxiliary door 20.
[0076] Specifically, the handle body 23 includes a connecting portion and a gripping portion, one end of the connecting portion is connected to the outer side of the auxiliary door 20, and the other end of the connecting portion is connected to the gripping portion. A rotating shaft 341 is provided on the side of the gripping portion facing the auxiliary door 20, and the first end of the pressing piece 24 is rotatably provided on the rotating shaft 341 of the gripping portion. The rotation of the pressing piece 24 in the first direction means that the second end of the pressing piece 24 rotates in a direction away from the handle body 23, and the rotation of the pressing piece 24 in the second direction means that the second end of the pressing piece 24 rotates in a direction close to the handle body 23.
[0077] Optionally, the pressing sheet 24 is provided with a first through hole, and the first rod body 351 is provided with a second through hole. A transmission rod 25 is provided between the pressing sheet 24 and the first rod body 351, and the first end of the transmission rod 25 is inserted and clamped in the first through hole, and the second end of the transmission rod 25 is inserted and clamped in the second through hole. The transmission rod 25 is made of a rigid material, and the pressing sheet 24 can drive the first rod body 351 to move through the transmission rod 25.
[0078] like Figure 1 As shown, the embodiment of the present disclosure further provides a refrigeration device, including a box body 01 provided with an opening. The refrigeration device also includes the above-mentioned door body assembly 02. The door body assembly 02 is arranged at the opening of the box body 01, and the main door 10 is arranged between the auxiliary door 20 and the box body 01.
[0079] Specifically, the main door 10 is rotatably disposed on the cabinet 01 of the refrigeration device through a main door hinge, and the main door 10 can be rotated around the main door hinge to open or close the opening of the cabinet 01.
[0080] If the size of the stored items is large, the user can rotate the pressing sheet 24 in the first direction so that the pressing sheet 24 drives the locking structure to lock the hinge shaft 212. At this time, the auxiliary door 20 is locked to the main door 10, and the user can pull the auxiliary door 20 and the main door 10 to rotate together through the door handle 22. If the size of the stored items is small, the user can rotate the pressing sheet 24 in the second direction so that the pressing sheet 24 drives the locking structure to unlock the hinge shaft 212. At this time, the auxiliary door 20 is unlocked from the main door 10, and the user can pull the auxiliary door 20 to rotate alone through the door handle 22. With this arrangement, there is no need to separately set up structures such as lock hooks, which can reduce the thickness of the door body of the auxiliary door 20, thereby improving the aesthetics.
[0081] Optionally, the refrigeration device is a door-in-door refrigerator.
