[0039] In addition, the air conditioner air outlet is added to the instrument frame, the air volume collecting port is added to the headrest of the driver's seat, and the cold air supply device is arranged in the driver's seat to realize that the cooling air blows over the driver's face, is directly collected through the air collecting port of the headrest of the driver's seat, is cooled again through the cold air supply device, and is blown out again, so that the circulating directional cold air can improve the driver's soberness during driving for a long time. In this way, the safety hidden danger caused by traditional fatigue driving can be reduced, the driver can have a sober driving thought during long-distance driving, and the safety and anti-drowsiness ability of long-distance driving are ensured.
[0040] The air collecting baffles 4 are arranged on both sides of the headrest 6 of the driver's seat to collect more cold air, so that the directional collection of cold air is achieved, the influence on the overall temperature in the vehicle is reduced, and the influence on the comfort of other passengers is reduced.
[0041] The cold air supply device is arranged at the backrest 10 of the driver's seat, and the air collecting port and the air outlet are communicated through a pipeline which is hidden in the seat.
[0042] In the embodiment, the cold air supply device is an air compressor 9. It can be understood that in some other embodiments, other cooling devices can also be used as long as the requirements are met, and the device is not limited to the air compressor in the embodiment.
[0043] The pipeline is hidden in the driver's seat and includes a first connecting pipe 5, a second connecting pipe 8, a third connecting pipe 12 and a fourth connecting pipe 7. The first connecting pipe 5 is connected between the headrest 6 of the driver's seat and the backrest 10 of the driver's seat, one end of which is communicated with the air collecting port and the other end of which is connected with the second connecting pipe 8.

The air conditioning system of the embodiment can be started by the driver or automatically started by the monitoring device. The monitoring device monitors the driver's yawning action and eyes through a camera, and if the driver is in a fatigue state, the driver anti-drowsiness air conditioning system of the embodiment is automatically started, so as to relieve or help the driver to overcome the fatigue state.
[0045] Embodiment two
[0046] The working method of the driver anti-drowsiness air conditioning system according to the embodiment one includes the following steps:
[0047] When the driver appears in the state of fatigue driving, the active opening or monitoring device starts the driver anti-drowsy air conditioning system, and the cold air supply device starts to work. The cooled cold air is blown to the driver's head through the air outlet, the air collector sends the cold air back to the cold air supply device, the cold air supply device sends the cooled air out again, and the cycle is continued. The temperature of the driver's head space is kept at a relatively low state, and the purpose of keeping the driver awake is achieved.
[0048] According to the opening of different types of air outlets, multiple working modes are set.

The directional blowing mode only opens the round hole air outlet 1. The strong blowing mode opens all the air outlets.
[0049] The specific working modes of the regular blowing mode, the directional blowing mode and the strong blowing mode are briefly introduced below.
[0050] Regular blowing mode: when the driver appears in the state of fatigue driving, the active opening or monitoring device starts the driver anti-drowsy air conditioning system. If the regular blowing mode is selected, the air compressor 9 receives the working signal, starts the air conditioning cooling work, and blows the cold air to the driver's face through the horizontal air outlet 2 and the vertical air outlet 3 through the third connecting pipe 12 and the fourth connecting pipe 7 inside the main driver seat cushion 11. The round hole air outlet 1 is closed under the action of the baffle. After the cold air passes through the driver's face, it is collected through the air collector on both sides of the main driver seat headrest 6 under the suction of the air compressor 9 inside the main driver seat backrest 10. The air is sent back to the air compressor 9 through the first connecting pipe 5 and the second connecting pipe 8. The air compressor 9 sends the cooled air out again, and the cycle is continued. The temperature of the driver's head space is kept at a relatively low state, and the purpose of keeping the driver awake is achieved.
[0051] The directional blowing mode: when the driver appears the fatigue driving state, the driver anti-drowsy air conditioning system can be started by the active opening or monitoring device, if the directional blowing mode is selected, the air compressor 9 receives the working signal, starts the air conditioning cooling work, the cold air is sent to the driver's face through the third connecting pipe 12, the fourth connecting pipe 7 in the main driver seat cushion 11, the horizontal air outlet 2 and the vertical air outlet 3 are closed under the action of the baffle. At this time, the driver can adjust the angle and direction of the round hole air outlet 1 at will, and can blow the forehead, eyes, face, temple and other directional positions of the face, so as to strengthen the wakefulness. After the cold air passes through the driver's face, the cold air is collected through the air collecting port on both sides of the main driver seat headrest 6 under the suction of the air compressor 9 in the main driver seat backrest 10, and then sent back to the air compressor 9 through the first connecting pipe 5 and the second connecting pipe 8. The air compressor 9 sends out the cooled air again, and the cycle is continued, so that the temperature of the driver's head space is kept at a relatively low state, and the purpose of keeping the driver awake driving is achieved.
[0052] The strong blowing mode: when the driver appears the fatigue driving state, the driver anti-drowsy air conditioning system can be started by the active opening or monitoring device, if the strong blowing mode is selected, the air compressor 9 receives the working signal, starts the air conditioning cooling work, the round hole air outlet 1, the horizontal air outlet 2 and the vertical air outlet 3 are opened, the cold air is sent to the driver's face through the third connecting pipe 12, the fourth connecting pipe 7 in the main driver seat cushion 11, the horizontal air outlet 2 and the vertical air outlet 3. After the cold air passes through the driver's face, the cold air is collected through the air collecting port on both sides of the main driver seat headrest 6 under the suction of the air compressor 9 in the main driver seat backrest 10, and then sent back to the air compressor 9 through the first connecting pipe 5 and the second connecting pipe 8. The air compressor 9 sends out the cooled air again, and the cycle is continued, so that the temperature of the driver's head space is kept at a relatively low state, and the purpose of keeping the driver awake driving is achieved, and the driving safety is improved.
