An actuator 5 is provided outside the air duct 6, and a damper 8 is rotatably connected inside the air duct 6, and one end of the damper 8 is fixedly connected to the output end of the actuator 5. The actuator 5 is controllably connected to a controller 3, and the controller 3 can adjust the angle of the damper 8 by controlling the actuator 5 to control the switch of the air outlet of the air conditioner and the air volume. A key switch 2 electrically connected to the controller 3 is provided on the air outlet window 1. By operating the key switch 2, the damper 8 can be controlled through the controller 3 and the actuator 5, so that the individual control of different air outlet windows 1 can be achieved, which can effectively meet the needs of passengers in different positions in the car and greatly improve the riding comfort of passengers.

[0036] Reference Figure 1 and Figure 2 The air duct 6 is in the shape of a rectangular cylinder as a whole, and the damper 8 is in the shape of a rectangular plate as a whole, and the length direction of the damper 8 is perpendicular to the air supply direction in the air duct 6.

The end face of the key switch 2 for interacting with the user is set to be an oblong shape, so as to avoid the harm of sharp corners to the user. A connector 22 is provided at the end of the key switch 2 away from the user. The connector 22 is electrically connected to the first connection end of the controller 3 through the first wiring harness 4, and the second connection end of the controller 3 is electrically connected to the control end of the actuator 5 through the second wiring harness 7. When the key switch 2 is triggered, the key switch 2 sends a switch signal, and the switch signal is transmitted to the controller 3 through the first wiring harness 4.
