The air conditioning damper is a key component that controls the direction and volume of airflow from the air conditioner, and the performance of its rotation adjustment mechanism directly affects the effectiveness of the air conditioning.

[0003] Currently, existing automotive air conditioning damper rotation adjustment mechanisms have some shortcomings. Some mechanisms use manual adjustment, which is not convenient to operate and has low adjustment accuracy; others use electric adjustment, but the drive structure is complex and prone to failure. At the same time, the limit is not precise enough, which may cause the damper to be over-rotated and damaged. Therefore, a new automotive air conditioning damper rotation adjustment mechanism is proposed to solve the above problems. Utility Model Content

[0019] The following is in conjunction with the appendix Figure 1-3This application will be described in further detail.

[0020] This application discloses a rotary adjustment mechanism for an automotive air conditioning damper. (Refer to...) Figure 1-3 A rotating adjustment mechanism for an automotive air conditioning damper includes an air conditioning housing 1, which serves as the mounting base for the entire mechanism. The top outer wall of the air conditioning housing 1 is respectively provided with a face-blowing damper 2 and a defrosting damper 3. The face-blowing damper 2 controls the airflow directed towards the face of the occupants, while the defrosting damper 3 controls the airflow directed towards the windows to remove frost and fog. A foot-blowing damper 4 is provided on one side of the outer wall of the air conditioning housing 1, which controls the airflow directed towards the feet of the occupants. To achieve precise adjustment of each damper, rotating adjustment mechanisms are installed inside the face-blowing damper 2, the defrosting damper 3, and the foot-blowing damper 4.

[0021] The rotary adjustment mechanism includes a secondary rotating shaft 6, an adjusting plate 7, a swing rod 8, and a main rotating shaft 9. Two mounting frames 5 are fixedly connected to the inner wall of the air conditioning housing 1, where the face air damper 2, defrost air damper 3, and foot air damper 4 are located. The mounting frames 5 provide mounting support for the various components of the rotary adjustment mechanism. Multiple secondary rotating shafts 6 and the main rotating shaft 9 are rotatably connected to the inner wall of the mounting frames 5, allowing them to rotate flexibly around their own axes. The main rotating shaft 9 is located between the multiple secondary rotating shafts 6, playing a leading role in the rotation. One end of the main rotating shaft 9 and the multiple secondary rotating shafts 6 passes through the mounting frame 5 and is fixedly connected to the swing rod 8, enabling the rotation of the main rotating shaft 9 and the secondary rotating shafts 6 to drive the swing rod 8 to move synchronously. A connecting rod 17 is hinged to the bottom of the multiple swing rods 8, allowing the movement of the multiple swing rods 8 to be linked. Multiple adjusting plates 7 are respectively fixedly connected to the outer walls of the multiple secondary rotating shafts 6 and the main rotating shaft 9. As the secondary rotating shafts 6 and the main rotating shaft 9 rotate, the adjusting plate 7 can change the ventilation area of ​​the air damper, thereby achieving airflow adjustment.

[0022] Multiple regulating plates 7 are located inside the mounting frame 5. This arrangement ensures that the regulating plates 7 can stably adjust the airflow within the mounting frame 5, avoiding interference with external components. Multiple auxiliary rotating shafts 6 are evenly distributed in a linear array with equal spacing between them and the main rotating shaft 9 on the inner wall of the mounting frame 5. This distribution ensures that the spacing between each regulating plate 7 is consistent, enabling uniform adjustment of the airflow and guaranteeing the stability and uniformity of the airflow.

[0023] Two mounting brackets 10 are fixedly connected to the outer wall of the air conditioner housing 1. The mounting brackets 10 provide a stable mounting position for the drive components. Servo motors 16 are fixedly mounted on the outer wall of the mounting brackets 10 via brackets 15. The brackets 15 can firmly fix the servo motors 16 on the mounting brackets 10, ensuring the stability of the servo motors 16 when they are working. The output shafts of the two servo motors 16 pass through the brackets 15 and the mounting brackets 10 and are fixedly connected to the ends of the two main rotating shafts 9. When the servo motors 16 are working, the rotation of their output shafts can directly drive the main rotating shafts 9 to rotate, and then drive the entire rotation adjustment mechanism to operate through the main rotating shafts 9, thereby realizing the adjustment of the damper.

[0024] Both mounting brackets 10 have a limiting mechanism installed on their outer walls. The limiting mechanism is used to limit the rotation angle of the main shaft 9 to prevent damage to the components due to excessive rotation. The limiting mechanism includes a limiting frame 11 and a drive rod 13. The limiting frame 11 is fixedly connected to the bottom outer wall of the mounting bracket 10. A limiting groove 12 is opened on its outer wall. The shape and length of the limiting groove 12 are designed according to the maximum rotation angle required by the main shaft 9.

[0025] The drive rod 13 is rotatably connected to the outer wall of the end of the main rotating shaft 9, and the drive rod 13 is located between the mounting bracket 10 and the support 15. When the main rotating shaft 9 rotates, it will drive the drive rod 13 to rotate synchronously. The bottom end of the drive rod 13 is fixedly connected to a movable block 14, which is movably connected to the inner wall of the limiting groove 12. When the main rotating shaft 9 rotates, the movable block 14 slides in the limiting groove 12. When the movable block 14 slides to both ends of the limiting groove 12, it will be blocked, thereby limiting the main rotating shaft 9 from continuing to rotate, thus effectively limiting the rotation angle of the main rotating shaft 9.

[0026] The implementation principle of the rotating adjustment mechanism of an automotive air conditioning damper in this application embodiment is as follows: when it is necessary to adjust the air volume of a certain damper, the servo motor 16 corresponding to the damper is started, and the output shaft of the servo motor 16 rotates. Since the end of its output shaft is fixedly connected to the end of the main rotating shaft 9, it will directly drive the main rotating shaft 9 to rotate around its own axis.

[0027] When the main rotating shaft 9 rotates, the adjusting plate 7 fixedly connected to its outer wall rotates synchronously. At the same time, the swing rod 8 fixedly connected to one end of the main rotating shaft 9 through the mounting frame 5 also rotates. Because the bottom ends of multiple swing rods 8 are hinged together with connecting rods 17, when the main rotating shaft 9 drives the corresponding swing rod 8 to rotate, the connecting rods 17 will be pushed or pulled, thereby driving other swing rods 8 fixedly connected to the auxiliary rotating shaft 6 to move synchronously, so that multiple auxiliary rotating shafts 6 rotate together with the main rotating shaft 9, and the adjusting plate 7 on the outer wall of each auxiliary rotating shaft 6 also rotates accordingly.

[0028] As the main rotating shaft 9 and multiple auxiliary rotating shafts 6 rotate, the adjusting plate 7 changes its angle within the mounting frame 5, thereby changing the ventilation area of ​​the damper. When the adjusting plates 7 are close to each other, the ventilation area decreases and the air volume decreases. When the adjusting plates 7 are far apart, the ventilation area increases and the air volume increases, thus achieving air volume adjustment for blowing on the face, defrosting, or blowing on the feet.

[0029] During the rotation of the main shaft 9, the drive rod 13 rotatably connected to the outer wall of its end will rotate synchronously. The movable block 14 at the bottom of the drive rod 13 slides in the limiting groove 12 of the limiting frame 11. When the movable block 14 slides to both ends of the limiting groove 12, it will be blocked, limiting the main shaft 9 from continuing to rotate, thereby avoiding excessive rotation of the adjusting plate 7, which could cause damage to the components or excessive closing / opening of the damper, and ensuring the safety and stability of the adjustment process.

[0030] Through this linkage mechanism, the entire rotary adjustment mechanism can stably and accurately adjust the airflow of each car air conditioning damper to meet different airflow needs inside the vehicle.
