[0037] In order to provide a further understanding of the purpose, structure, features, and functions of the present application, the following detailed description is given in conjunction with the embodiments.

[0038] In view of the problem that the bottle holder cover is inconvenient to operate and has poor sealing effect, the present application provides a door assembly 101, including a door body 102, a control member arranged on the door body 102, and a wall cabinet 103; the wall cabinet 103 includes a first bottle holder 1, a top plate 2, and a first side plate 3 and a second side plate 4 arranged opposite to each other, wherein the first bottle holder 1, the top plate 2, the first side plate 3, and the second side plate 4 form an accommodating space; the first bottle holder 1 includes a first panel 11 and a first cover plate 12 arranged in parallel on the front side of the first bottle holder 1, and the control member is configured as follows:

[0039] When it is detected that the door body 102 is closed, the control component controls the first cover plate 12 to move away from the first panel 11 to seal the accommodating space with the first panel 11;

[0040] When it is detected that the door body 102 is opened, the control component controls the first cover plate 12 to move toward the first panel 11 to open the accommodating space.

[0041] Specifically, the wall cabinet 103 is arranged on the inner wall of the door body 102, that is, the door body 102 is used to close an open box when closed, and the wall cabinet 103 is arranged on the side wall of the door body 102 facing the box. The wall cabinet 103 includes a first bottle holder 1, a top plate 2 and a first side plate 3 and a second side plate 4 that are relatively arranged. The first bottle holder 1, the top plate 2, the first side plate 3 and the second side plate 4 form a accommodating space for storing items.

[0042] The first bottle holder 1 includes a first panel 11 and a first cover plate 12 which are arranged in parallel. The relative movement between the first panel 11 and the first cover plate 12 realizes the opening and closing of the accommodating space. Specifically, the first panel 11 and the first cover plate 12 are arranged relative to the door body 102, that is, the door body 102 serves as the rear side wall of the first bottle holder 1, and the first panel 11 and the first cover plate 12 are arranged on the front side wall of the first bottle holder 1.

[0043] When it is detected that the door body 102 is closed, the control component controls the first cover plate 12 to move away from the first panel 11 to seal the accommodating space with the first panel 11, that is, the first cover plate 12 and the first panel 11 produce a translational movement away from each other to cover the accommodating space and make it sealed.

[0044] When it is detected that the door body 102 is opened, the control component drives the first cover plate 12 to move toward the first panel 11, thereby opening the accommodating space to facilitate users to take and place items.

[0045] If the first panel 11 is disposed on the bottom wall of the first bottle holder 1 , the first cover plate 12 moves in a direction away from the first panel 11 , that is, the first cover plate 12 moves upward relative to the first panel 11 .

[0046] If the first panel 11 is disposed on the left side wall of the first bottle holder 1 , the first cover plate 12 moves away from the first panel 11 , that is, the first cover plate 12 moves rightward relative to the first panel 11 .

[0047] And so on, this application will not go into details.

[0048] The accommodating space includes a first opening portion, which includes a first part covered by a first cover plate 12; when the first cover plate 12 moves upward relative to the first panel 11, the first part gradually increases; when the first cover plate 12 moves downward relative to the first panel 11, the first part gradually decreases.

[0049] The accommodating space is a storage space formed by the first bottle holder 1 in the wall cabinet 103 . The first opening can be covered or opened by the first cover plate 12 , and the size of the first opening changes with the movement of the first cover plate 12 , that is, the opening degree of the first opening is adjusted by the movement of the first cover plate 12 .

[0050] Taking the first panel 11 disposed on the bottom wall of the first bottle holder 1 as an example, when the first cover plate 12 moves upward relative to the first panel 11, that is, moves in a direction away from the first panel 11, the portion covered by the first opening portion will gradually increase, and the closedness of the accommodating space will gradually increase. On the contrary, when the first cover plate 12 moves downward relative to the first panel 11, that is, moves in a direction close to the first panel 11, the portion covered by the first opening portion will gradually decrease, and the closedness of the accommodating space will gradually weaken, and more space will be opened, making it easier for users to take and put items.

[0051] By intelligently adjusting the position of the first cover plate 12, the opening and closing states of the accommodating space can be switched, which not only meets the airtightness requirement of the first bottle holder 1, but also improves the efficiency of easily taking and placing items.

[0052] In one embodiment, the wall cabinet 103 further includes a second bottle holder and a transmission module 5 disposed above the first bottle holder 1, the transmission module 5 includes a motor 51 disposed on the second bottle holder and a synchronous belt 52 sleeved on the motor 51 at the upper end, and the lower end of the synchronous belt 52 is connected to the first cover plate 12;

[0053] The control component controls the motor 51 to rotate, and the synchronous belt 52 drives the first cover plate 12 to move up and down.

[0054] In the present application, the wall cabinet 103 further includes a second bottle holder disposed above the first bottle holder 1 to provide an installation position for the transmission module 5. Specifically, the transmission module 5 includes a motor 51 and a synchronous belt 52 sleeved on the motor 51. The motor 51 is disposed on the second bottle holder. The synchronous belt 52 is an annular structure, with its upper end sleeved on the motor 51 and its lower end connected to the first cover plate 12. Of course, the motor 51 can also be disposed on other structures higher than the first bottle holder 1, such as the first side plate 3, the second side plate 4 or the top plate 2 of the wall cabinet 103.

[0055] The control component is responsible for detecting the open / closed state of the door body 102, and controls the rotation of the motor 51 according to the open / closed state of the door body 102. When it is detected that the door body 102 is closed, the control component sends a command to the motor 51 to make it rotate in the forward direction, thereby driving the synchronous belt 52 and the first cover plate 12 to move upward to close the accommodation space. On the contrary, when it is detected that the door body 102 is open, the control component sends a command to the motor 51 to make it rotate in the reverse direction, thereby driving the synchronous belt 52 and the first cover plate 12 to move downward to open the accommodation space.

[0056] This is to realize automatic control of the movement of the first cover plate 12, and further to automatically adjust the first cover plate 12 to close or open the accommodating space.

[0057] In an optional embodiment, the transmission module 5 further includes a synchronous wheel 53, the synchronous wheel 53 is disposed on the first panel 11, the synchronous belt 52 is simultaneously sleeved on the motor 51 and the synchronous wheel 53, the synchronous belt 52 further includes a connecting portion 521, and the connecting portion 521 is connected to the first cover plate 12;

[0058] When the motor 51 drives the synchronous belt 52 to rotate around the motor 51 and the synchronous wheel 53 , the connecting portion 521 drives the first cover plate 12 to move up and down.

[0059] The synchronous wheel 53 is arranged on the first panel 11, and the synchronous wheel 53 cooperates with the synchronous belt 52, so that the synchronous belt 52 rotates around the motor 51 and the synchronous wheel 53 under the drive of the motor 51. Through the setting of the synchronous wheel 53, the stability and reliability of the transmission of the synchronous belt 52 are improved, so that the first cover plate 12 can move up and down more smoothly.

[0060] A connection portion 521 is further provided below the synchronous belt 52, and the synchronous belt 52 is connected to the first cover plate 12 via the connection portion 521. When the synchronous belt 52 rotates around the motor 51 and the synchronous wheel 53, the power is transmitted to the first cover plate 12 via the connection portion 521, and the connection portion 521 drives the first cover plate 12 to move up and down, thus realizing a direct connection between the first cover plate 12 and the transmission module 5, thereby ensuring the synchronization and accuracy of the movement of the first cover plate 12 and the synchronous belt 52.

[0061] The connection between the specific connection portion 521 and the first cover plate 12 can be achieved through one or more connection methods such as bolts, riveting, winding or bonding, and the present application does not impose any specific limitation.

[0062] The motor 51 is provided with a first meshing portion 511 on its periphery, the synchronous wheel 53 is provided with a second meshing portion 531 on its periphery, and the synchronous belt 52 is provided with a third meshing portion 522 adapted to the first meshing portion 511 and the second meshing portion 531 on the inner side of the synchronous wheel 53 and close to the motor 51 .

[0063] The first meshing portion 511 is arranged on the outer periphery of the motor 51, and is used to transmit power between the motor 51 and the synchronous belt 52. The second meshing portion 531 is arranged on the outer periphery of the synchronous wheel 53, and corresponds to the third meshing portion 522 of the synchronous belt 52, so as to achieve a stable transmission effect on the synchronous belt 52. The third meshing portion 522 is arranged on the inner side of the synchronous belt 52, and is adapted to the first meshing portion 511 of the motor 51 and the second meshing portion 531 of the synchronous wheel 53. The third meshing portion 522 enables the synchronous belt 52 to fit tightly on the first meshing portion 511 of the motor 51 and the second meshing portion 531 of the synchronous wheel 53, so as to ensure the accuracy and stability of the transmission of the entire transmission module 5.

[0064] Since the synchronous belt 52 is tightly sleeved on the outer periphery of the motor 51, and the third meshing portion 522 of the synchronous belt 52 matches the first meshing portion 511, when the motor 51 is started, the first meshing portion 511 on the outer periphery of the motor 51 will start to rotate, and the power of the rotation of the motor 51 will be transmitted to the synchronous belt 52. As the synchronous belt 52 rotates, the synchronous wheel 53 will also be driven to start rotating, and the synchronous belt 52 starts to rotate around the motor 51 and the synchronous wheel 53. The third meshing portion 522 of the synchronous belt 52 will simultaneously maintain close contact with the first meshing portion 511 of the motor 51 and the second meshing portion 531 of the synchronous wheel 53, ensuring the continuity and stability of the transmission of the entire transmission module 5.

[0065] The present application achieves efficient and stable transmission effect through the meshing design between the motor 51, the synchronous wheel 53 and the synchronous belt 52. At the same time, since the meshing design between the motor 51, the synchronous wheel 53 and the synchronous belt 52 is simple and easy to understand, it is more convenient and quick to maintain and replace parts.

[0066] At least one side of the first cover plate 12 is provided with at least one guide wheel 120, and at least one of the first side plate 3 and the second side plate 4 is provided with a guide groove adapted to the guide wheel 120, and the guide wheel 120 slides up and down along the guide groove to drive the first cover plate 12 to move up and down.

[0067] The first side panel 3 and the second side panel 4 not only provide structural support for the wall cabinet 103, but also provide a guide space for the up and down movement of the first cover plate 12. Specifically, at least one side of the first cover plate 12 is provided with at least one guide wheel 120, and at least one of the first side panel 3 or the second side panel 4 is provided with a guide groove adapted to the guide wheel 120. When the first cover plate 12 moves up and down, the guide wheel 120 provided on the first cover plate 12 will slide along the guide groove. The guide groove provides a clear motion trajectory for the guide wheel 120, thereby ensuring the accuracy and stability of the movement of the first cover plate 12. The shape and size of the guide groove match the guide wheel 120 to ensure the close fit and effective guidance between the guide wheel 120 and the guide groove, thereby improving the stability of the movement of the first cover plate 12.

[0068] Taking the second side panel 4 as an example, the first side panel 3 has the same structure and will not be described in detail. The guide groove includes a vertically extending first section 411 and a second section 412 connected to the first section 411, and the second section 412 is bent relative to the first section 411 toward the first panel 11, and the angle between the first section 411 and the second section 412 is greater than 90 degrees.

[0069] In an optional embodiment, the first section 411 is a vertical extension portion of the guide groove, which is a main guiding portion, ensuring the linearity of the first cover plate 12 during the up and down movement.

[0070] The second section 412 is a bent portion connected to the first section 411, and the second section 412 is bent toward the first panel 11. When the first cover plate 12 is close to a fully opened or closed position, the second section 412 provides additional guiding and limiting functions.

[0071] The included angle between the first section 411 and the second section 412 is greater than 90 degrees, so that the first cover plate 12 can stop more smoothly when approaching the limit position, avoiding shaking or impact caused by inertia.

[0072] Taking the closing of the first cover 12 as an example, the guide wheel 120 first slides linearly from bottom to top in the first section 411. When the first cover 12 is close to the fully closed position, the guide wheel 120 enters the second section 412 and slowly moves away from the accommodating space. Finally, when the first cover 12 is fully closed, the first cover 12 is flush with the outer surface of the first panel 11, thereby realizing a closed accommodating space.

[0073] When the first cover plate 12 starts to open from being fully closed, those skilled in the art can easily obtain the movement state of the first cover plate 12 according to the design of the guide groove, which will not be described in detail here.

[0074] An upper guide wheel 121 and a lower guide wheel 122 are provided on both sides of the first cover plate 12, and an upper guide groove 41 adapted to the upper guide wheel 121 and a lower guide groove 42 adapted to the lower guide wheel 122 are provided on the first side plate 3 and the second side plate 4, and the upper guide groove 41 and the lower guide groove 42 have the same extension direction.

[0075] An upper guide wheel 121 and a lower guide wheel 122 are provided on both sides of the first cover plate 12. The upper guide wheel 121 and the lower guide wheel 122 are respectively responsible for providing guidance at the upper and lower ends of the first cover plate 12, thereby enhancing the stability of the first cover plate 12 during the up and down movement.

[0076] The first side plate 3 and the second side plate 4 are both provided with an upper guide groove 41 adapted to the upper guide wheel 121 and a lower guide groove 42 adapted to the lower guide wheel 122. Continuing to take the second side plate 4 as an example, the upper guide groove 41 and the lower guide groove 42 extend in the same direction, ensuring the stability of the first cover plate 12 during the up and down movement.

[0077] During the up and down movement of the first cover plate 12, the upper guide wheel 121 slides along the upper guide groove 41, and the lower guide wheel 122 slides along the lower guide groove 42. This double guide design enables the first cover plate 12 to maintain a more stable state during the movement, avoiding shaking or deviation caused by a single guide.

[0078] The lower end of the upper guide groove 41 at least partially intersects with the upper end of the lower guide groove 42. The lower end of the upper guide groove 41 and the upper end of the lower guide groove 42 are designed to at least partially intersect, and through a compact design, the guide system can provide efficient guiding in a limited space.

[0079] The groove width of the upper guide groove 41 is smaller than the groove width of the lower guide groove 42 .

[0080] The upper guide groove 41 has a narrower groove width, and it can only cooperate with the upper guide wheel 121 of smaller size; similarly, the lower guide groove 42 has a wider groove width, and can only cooperate with the lower guide wheel 122 of larger size. The upper guide wheel 121 and the lower guide wheel 122 slide in the upper guide groove 41 and the lower guide groove 42 respectively: the guide grooves of different widths cooperate with the guide wheel 120 to ensure the precise guidance of the first cover plate 12 during the up and down movement.

[0081] The groove width is the distance between the two sides of the guide groove perpendicular to the movement of the first cover plate 12 .

[0082] The groove depth of the upper guide groove 41 is greater than the groove depth of the lower guide groove 42 .

[0083] The upper guide groove 41 with a deeper depth cooperates with the upper guide wheel 121, and the lower guide groove 42 with a shallower depth cooperates with the lower guide wheel 122. It is ensured that when the first cover plate 12 moves downward, the upper guide wheel 121 will not slide into the lower guide groove 42, and because the lower guide wheel 122 is wider than the upper guide wheel 121, when the first cover plate 12 moves upward and the lower guide wheel slides to the intersection of the lower guide groove 42 and the upper guide groove 41, the lower guide wheel 122 will not slide into the upper guide groove 41.

[0084] The present application further provides a refrigerator 100, comprising the above-mentioned door assembly 101. The refrigerator 100 comprises a box body for accommodating items, and a door assembly 101 for covering an opening of the box body.

[0085] The present application relates to a door assembly 101 and a refrigerator 100, wherein the door assembly 101 comprises a door 102, a control member disposed on the door 102, and a wall cabinet 103; the wall cabinet 103 comprises a first bottle holder 1, a top plate 2, and a first side plate 3 and a second side plate 4 disposed opposite to each other, wherein the first bottle holder 1, the top plate 2, the first side plate 3, and the second side plate 4 form a storage space; the first bottle holder 1 comprises a first panel 11 and a first cover plate 12 disposed in parallel on the front side of the first bottle holder 1, and the control member is configured as follows: when the door 102 is detected to be closed, the control member controls the first cover plate 12 to move in a direction away from the first panel 11, and seals the storage space with the first panel 11; when the door 102 is detected to be opened, the control member controls the first cover plate 12 to move in a direction close to the first panel 11, and opens the storage space. The present application can automatically synchronize the opening and closing states of the bottle holder cover plate and the door 102, greatly improving the convenience of taking and placing items, and improving the sealing of the bottle holder area.
