For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0038] In the description of this specification, it should be understood that the directional terms such as "upper" and "lower" used in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should also be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0039] Reference Figure 1 and Figure 2 As shown in the figure, an embodiment of this application discloses an air conditioning damper device, which includes two frame side plates 1, a first frame end cap 2, a second frame end cap 3, a blade assembly 4, and a transmission assembly 5. The two frame side plates 1 are spaced apart, and each frame side plate 1 is provided with multiple mounting holes 102a. The multiple mounting holes 102a can be used to install the frame side plate 1 onto the target object to be installed (such as the air outlet or air inlet of a subway air conditioner) through a first connector (e.g., bolts). The first frame end cap 2 is detachably connected to one end of the two frame side plates 1, and the second frame end cap 3 is detachably connected to the other end of the two frame side plates 1, so that the first frame end cap 2, the second frame end cap 3, and the two frame side plates 1 can form a receiving part. The blade assembly 4 is received in the receiving part, and the transmission assembly 5 passes through the first frame end cap 2 and the second frame end cap 3. The transmission assembly 5 is connected to the blade assembly 4 by a plug-in connection. The transmission assembly 5 is used to drive the blade assembly 4 to rotate, so as to open or close the receiving part, thereby realizing the opening or closing of the air conditioning damper device.

[0040] In this embodiment, one end of the two frame side plates 1 is detachably connected to the first frame end cap 2 via a second connector (e.g., a bolt), and the other end of the two frame side plates 1 is detachably connected to the second frame end cap 3 via a third connector (e.g., a bolt).

[0041] This embodiment eliminates the welding connection method by making the frame side plate 1 detachably (e.g., threaded) connected to the first frame end cap 2 and the second frame end cap 3. This reduces the possibility of frame side plate deformation and can more effectively ensure the sealing between the blade assembly and the frame side plate. It effectively reduces or even prevents air leakage when the air conditioning damper device is closed. If welding is used, the frame side plate is prone to deformation, which can easily lead to air leakage in the air conditioning damper device. In addition, in this embodiment, if the air conditioning damper device is severely deformed or damaged, it can be disassembled and repaired on-site, making maintenance more convenient.

[0042] To further reduce the possibility of deformation of the frame side plate 1, the air conditioning damper device also includes multiple reinforcing plates 9. These reinforcing plates 9 are evenly spaced along the length of the frame side plate 1, and each reinforcing plate 9 has its two ends connected to two frame side plates 1 respectively. For example, the two ends of each reinforcing plate 9 can be riveted to the two frame side plates 1 respectively. At least some of the mounting holes 102a are positioned corresponding to the positions of the reinforcing plates 9. For example, at least some of the mounting holes 102a are positioned close to the reinforcing plates 9. In this embodiment, the distance between at least some of the mounting holes 102a and the reinforcing plates 9 is less than a preset value, such as 5 cm, 4 cm, or 3 cm. This embodiment effectively prevents the frame side plate 1 from being deformed by the mounting bolts by providing reinforcing plates 9 between the two frame side plates 1 and positioning at least some of the mounting holes 102a close to the reinforcing plates 9. In related technologies, when the frame side plate is installed on the target object through mounting holes and bolts, the frame side plate is easily deformed by the pulling of the bolts. In this embodiment, when installing the frame side plate 1, the force applied to the frame side plate 1 by the reinforcing plate 9 can effectively prevent the frame side plate 1 from being deformed by the pulling of the mounting bolts. At the same time, the reinforcing plate 9 can also serve as a mounting bracket for the temperature detector. Therefore, the setting of the reinforcing plate 9 also facilitates the installation of the temperature detector.

[0043] Reference Figure 3 As shown, the air conditioning damper device also includes multiple threaded plates 6. These threaded plates 6 can be connected to the first frame head 2 and the second frame head 3 respectively by riveting. The frame side plate 1 is threadedly connected to the threaded plates 6 to achieve a detachable connection between the frame side plate 1 and the first frame head 2 and the second frame head 3. In this embodiment, four threaded plates 6 are provided. Two threaded plates 6 are respectively located on opposite sides of the first frame head 2, and these two threaded plates 6 located on opposite sides of the first frame head 2 can be riveted to the sides of the first frame head 2. The other two threaded plates 6 are respectively located on opposite sides of the second frame head 3, and these two threaded plates 6 located on opposite sides of the second frame head 3 can be riveted to the sides of the second frame head 3. Two frame side plates 1 are located on both sides of the first frame head 2 and the second frame head 3, respectively. One end of each frame side plate 1 can be threadedly connected to two threaded plates 6 located on both sides of the first frame head 2 by bolts (i.e., second connectors). The other end of each frame side plate 1 is threadedly connected to two threaded plates 6 located on both sides of the second frame head 3 by bolts (i.e., third connectors), thereby forming a rectangular frame with a receiving part by the two frame side plates 1, the first frame head 2 and the second frame head 3.

[0044] Reference Figure 4As shown, each frame side panel 1 includes a connecting part 101 and a mounting part 102. The mounting part 102 is connected to the connecting part 101, forming an L-shaped cross-section. The two ends of the reinforcing plate 9 are respectively connected to the connecting parts 101 of the two frame side panels 1. The mounting part 102 is provided with multiple mounting holes 102a. In this embodiment, by setting the cross-section of the frame side panel 1 to an L-shaped structure, the assembly and installation of the frame side panels are facilitated.

[0045] Reference Figure 5 and Figure 6 As shown, the transmission assembly 5 includes a drive shaft 51, a first driven shaft 52, a second driven shaft 53, a third driven shaft 54, and a connecting rod 55. The drive shaft 51 and the first driven shaft 52 are rotatably mounted on the first frame head 2, and the second driven shaft 53 and the third driven shaft 54 ​​are rotatably mounted on the second frame head 3. The two ends of the connecting rod 55 are respectively connected to the second driven shaft 53 and the third driven shaft 54. Specifically, the transmission assembly 5 also includes a washer 56, an anti-slip pad 57, and a nut 58. The second driven shaft 53 includes a first connecting post 531, and the third driven shaft 54 ​​includes a second connecting post 541. The two ends of the connecting rod 55 are respectively provided with a first connecting hole 551 and a second connecting hole 552. The first frame head 2 is provided with a first through hole and a second through hole, and the second frame head 3 is provided with a third through hole and a fourth through hole. During assembly, the drive shaft 51 is inserted through the first through hole, the first driven shaft 52 is inserted through the second through hole, the second driven shaft 53 is inserted through the third through hole, and the third driven shaft 54 ​​is inserted through the fourth through hole. Then, the first connecting hole 551 of the connecting rod 55 is fitted onto the first connecting post 531, and the second connecting hole 552 of the connecting rod 55 is fitted onto the second connecting post 541. Then, the washer 56, the anti-slip pad 57, and the nut 58 are sequentially fitted onto the first connecting post 531 and the second connecting post 541, so that the second driven shaft 53 and the third driven shaft 54 ​​are movably connected through the connecting rod 55.

[0046] Continue to refer to Figure 5 and Figure 6As shown, the air conditioning damper device also includes a mounting plate 11 and multiple partitions 10. The mounting plate 11 is disposed on the side of the first frame head 2 facing away from the blade assembly 4, and the mounting plate 11 can be riveted to the first frame head 2. The mounting plate 11 can be used to install a damper actuator, which can be used to control the rotation of the drive shaft 51. At least one partition 10 is disposed between the first end of the blade assembly 4 and the first frame head 2, and at least one partition 10 is disposed between the second end of the blade assembly 4 and the second frame head 3. The drive shaft 51 passes through the mounting plate 11, the first frame head 2, and the corresponding partitions 10. The first driven shaft 52 passes through the first frame head 2 and the corresponding partitions 10. The second driven shaft 53 and the third driven shaft 54 ​​pass through the second frame head 3 and the corresponding partitions 10. In this embodiment, the installation of the mounting plate 11 facilitates the installation of the damper actuator. The partition plate 10 reduces the gap between the two ends of the blade assembly and the first frame end cap 2 and the second frame end cap 3, further reducing or even preventing air leakage when the air conditioning damper is in the closed state.

[0047] Reference Figure 7 and Figure 8 As shown, the blade assembly 4 includes a first blade 41 and a second blade 42. The two ends of the first blade 41 are connected to the drive shaft 51 and the second driven shaft 53, respectively, and the two ends of the second blade 42 are connected to the first driven shaft 52 and the third driven shaft 54, respectively. When controlling the damper device to close or open, the drive shaft 51 can be driven to rotate. The drive shaft 51 can drive the first blade 41 to rotate, and the rotation of the first blade 41 can drive the second driven shaft 53, the connecting rod 55, the third driven shaft 54, and the second blade 42 to rotate, thereby realizing the opening or closing of the air conditioning damper device.

[0048] To improve the stability of the air conditioning damper device, the air conditioning damper device also includes multiple limiting members 7 and multiple locking members 8. At least one limiting member 7 is connected to the first frame end cap 2 and extends toward the receiving part to limit the rotation angle of the first blade 41. At least one limiting member 7 is connected to the third driven shaft 54 ​​and extends toward the receiving part to limit the rotation of the connecting rod 55. Partial locking member 8 is used to lock the first blade 41 to the drive shaft 51 and the second driven shaft 53, and partial locking member 8 is used to lock the second blade 42 to the first driven shaft 52 and the third driven shaft 54. In an exemplary embodiment, there are four locking members 8, namely a first locking member, a second locking member, a third locking member and a fourth locking member. The first locking member is used to connect one end of the first blade 41 to the drive shaft 51, the second locking member is used to connect the other end of the first blade 41 to the second driven shaft 53, the third locking member is used to connect one end of the second blade 42 to the first driven shaft 52, and the fourth locking member is used to connect the other end of the second blade 42 to the third driven shaft 54. That is, partial locking member 8 is used to lock the first blade 41 to the drive shaft 51 and the second driven shaft 53, and partial locking member 8 is used to lock the second blade 42 to the first driven shaft 52 and the third driven shaft 54. In this embodiment, the limiting member 7 can limit the rotation angle of the blade and the rotation angle of the connecting rod 55, effectively preventing the blade from rotating to its dead point and getting stuck. In some embodiments, the limiting member 7 can be a limiting post or a rivet, and the locking member 8 can be a screw.

[0049] Accordingly, this application also provides an air conditioning system, including an air conditioning damper device as described in any of the above embodiments. The air conditioning damper device is installed on the target object to be installed (e.g., the air outlet or air inlet of the air conditioning system), and the airflow direction and flow rate are controlled by opening or closing the air conditioning damper device to meet the user's needs.

[0050] This application reduces air leakage and improves the maintenance efficiency and cost of the air conditioning damper by changing the structure of the damper frame from welded aluminum profiles to sheet metal splicing. When users report problems such as jamming of the air conditioning damper, on-site repairs can be carried out, improving the speed of problem response. At the same time, since the air conditioning damper is assembled by bolting sheet metal parts, when the frame deforms or breaks during use, the damaged parts can be replaced on-site, making maintenance more convenient, further reducing maintenance costs and improving maintenance efficiency.

[0051] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
