Description

Technical Field

[0001] The invention relates to the technical field of driver assistance, and in particular to a driver anti-drowsiness air conditioning system and a working method. Background Art

[0002] Drivers often feel drowsy during long-distance driving because they are in a constant temperature environment for a long time, which can easily lead to safety hazards.

[0003] The Chinese utility model patent with announcement number CN212709241 U discloses a safety reminder device for preventing fatigue driving. Based on the existing vehicle air conditioning system, it determines whether the driver is driving fatigued through face recognition, and controls the vehicle air conditioning system while giving a buzzer alarm through the feedback warning structure, so that the vehicle air conditioning system is cooled quickly, lowering the temperature inside the car, and stimulating the driver through the circulation of cold air and the alarm sound to avoid dozing off, reminding the driver, and greatly improving the safety of car driving. Although lowering the temperature inside the car can prevent the driver from dozing off, if the low temperature applied for a short time is lifted, the driver is prone to dozing off again, and if the low temperature is applied for a long time, it will affect the comfort of other passengers. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a driver anti-drowsiness air conditioning system and working method, by adding air outlets around the driving instrument, blowing air to the driver's head through the air outlets, and adding directional air collection ports on the headrest of the main driver's seat, so as to achieve directional blowing and directional recovery of cold air for driver anti-fatigue, and avoid affecting the comfort of other passengers in the car. In order to achieve the above purpose, the present invention is implemented through the following technical solutions:

[0005] In a first aspect, the present invention provides a driver anti-drowsiness air conditioning system, comprising:

[0006] The air outlet is set on the instrument frame of the driver's seat, and the air flows toward the driver's head;

[0007] Air collecting vents are arranged on both sides of the driver's seat headrest and are used to collect the air blown out of the air outlets;

[0008] A cold air supply device is connected to the air collecting port at one end and to the air outlet at the other end; the cold air supply device sucks in the air around the air collecting port, cools it, and then ejects it through the air outlet, thereby forming a cold air circulation.

[0009] As a further implementation, the air outlet is provided in plurality, and the types include circular hole air outlet, horizontal air outlet and vertical air outlet.

[0010] As a further implementation method, the blowing direction of the circular air outlet is adjustable, and the blowing direction covers the forehead, eyes, face, and temple areas.

[0011] As a further implementation method, wind collecting baffles for collecting wind are arranged on both sides of the driver's seat headrest.

[0012] As a further implementation method, the cold air supply device is arranged at the backrest of the main driver's seat, and is connected to the air collecting port and the air outlet through a pipe, and the pipe is hidden in the seat.

[0013] As a further implementation, the cold air supply device is an air compressor.

[0014] As a further implementation, a monitoring device is also included for identifying whether the driver is in a fatigue state to determine whether to turn on the cold air supply device.

[0015] In a second aspect, the present invention provides a working method of the driver anti-drowsiness air conditioning system according to the first aspect, comprising the following steps:

[0016] When the driver is driving fatigued, the driver's anti-drowsiness air conditioning system is actively turned on or the monitoring device starts, the cold air supply device starts working, and the cooled cold air is blown to the driver's head through the air outlet. The air collecting port sends the cold air back to the cold air supply device, and the cold air supply device cools the air again and sends it out, and the cycle continues to keep the temperature of the driver's head space at a relatively low state, so as to achieve the purpose of keeping the driver awake while driving.

[0017] As a further implementation method, multiple working modes are set according to opening different types of air outlets.

[0018] As a further implementation method, the working modes include conventional blowing mode, directional blowing mode and strong blowing mode. The conventional blowing mode only opens the horizontal air outlets and vertical air outlets, the directional blowing mode only opens the circular hole air outlets, and the strong blowing mode opens all air outlets.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The present invention adds air outlets around the driving instrument, blows air to the driver's head in a directional manner through the air outlets, and adds directional air collection outlets at the headrest of the main driver's seat, so as to achieve directional blowing and directional recovery of cold air for the driver's fatigue prevention, thereby avoiding affecting the comfort of other passengers in the car.

[0029] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0030] Embodiment 1

[0031] In a typical embodiment of the present invention, reference is made to Figure 1 and Figure 2 As shown, a driver anti-drowsiness air conditioning system includes an air outlet, an air collecting outlet and a cold air supply device.

[0032] The air outlet is set on the instrument frame of the driver's seat, and the air outlet direction is towards the driver's head. It is not difficult to understand that the air outlet is set on the instrument frame area close to the driving position, and the air outlet is independently set compared to the original air-conditioning outlet, and the blowing direction of the air outlet can blow towards the driver's head.

[0033] The number of air outlets is multiple, and the types are also different, so that the air outlet has a larger blowing area and avoids the existence of a blowing dead angle. In this embodiment, a circular hole air outlet 1, a horizontal air outlet 2 and a vertical air outlet 3 are provided. The circular hole air outlet 1, the horizontal air outlet 2 and the vertical air outlet 3 can be closed and opened independently, and one of the air outlets can be opened or closed at will when needed to meet the different needs of the driver.

[0034] The blowing direction of the circular air outlet 1 is adjustable, and its blowing direction covers the forehead, eyes, face, temples and other areas.

[0035] It is understandable that the specific installation position of the air outlet is not limited to Figure 1 As shown in the position, in some other embodiments, it is sufficient as long as the wind from the air outlet can blow to the driver's head area, but the blind spots of the air outlet should be reduced as much as possible.

[0036] The air collecting vents are arranged on both sides of the driver's seat headrest 6 to collect the air blown out of the air outlets.

[0037] One end of the cold air supply device is connected to the air collecting port, and the other end is connected to the air outlet; the cold air supply device sucks the airflow around the air collecting port, cools it, and then sprays it out through the air outlet, thereby forming a cold air circulation.

[0038] In this embodiment, air outlets are added around the driving instrument to blow air toward the driver's head in a directional manner through the air outlets, and directional air collecting outlets are added at the headrest 6 of the main driver's seat to achieve directional blowing and directional recovery of cold air for the driver's fatigue prevention, thereby avoiding affecting the air-conditioning temperature of other passengers in the car.

[0039] In addition, air-conditioning outlets are added to the instrument frame, air volume air collection outlets are added to the driver's seat headrest, and a cold air supply device is installed inside the driver's seat. After the cooled air blows over the driver's face, it is directly recovered through the air collection outlet of the driver's seat headrest, cooled again by the cold air supply device, and blown out again, achieving circulating directional cold air, which can improve the driver's mental clarity for a long time. This can reduce the safety hazards caused by traditional fatigue driving, and can assist the driver to have a clear driving mind when driving long distances, ensuring the safety and anti-drowsiness ability of long-distance driving.

[0040] Wind collecting baffles 4 for collecting wind are arranged on both sides of the driver's seat headrest 6 to collect more cold air, thereby achieving the purpose of directional collection of cold air, reducing the impact on the overall temperature in the car, and reducing the impact on the comfort of other passengers.

[0041] The cold air supply device is arranged at the backrest 10 of the main driver's seat, and is connected to the air collecting port and the air outlet through a pipeline, and the pipeline is hidden in the seat.

[0042] In this embodiment, the cold air supply device is an air compressor 9. It is understandable that in other embodiments, other cooling devices may be used as long as they can meet the requirements, and are not limited to the air compressor in this embodiment.

[0043] Most of the pipes are hidden inside the driver's seat, including the first connecting pipe 5, the second connecting pipe 8, the third connecting pipe 12 and the fourth connecting pipe 7. The first connecting pipe 5 is connected between the driver's seat headrest 6 and the driver's seat backrest 10, one end of which is connected to the air collecting port, and the other end is connected to the second connecting pipe 8. The second connecting pipe 8 is arranged in the driver's seat backrest 10, and the other end thereof is connected to the air inlet of the air compressor 9. The air outlet of the air compressor 9 is connected to the third connecting pipe 12, and the third connecting pipe 12 is arranged in the driver's seat cushion 11. One end of the fourth connecting pipe 7 is connected to the third connecting pipe 12, and the other end is connected to the air outlet, and the cooling air is blown to the driver's head through the air outlet.

[0044] This embodiment further includes a monitoring device for identifying whether the driver is in a fatigued state to determine whether to turn on the cold air supply device. The air conditioning system of this embodiment can be actively turned on by the driver or automatically turned on by the monitoring device. The monitoring device monitors the driver's yawning and eyes through a camera. If the driver is in a fatigued state, the driver's anti-drowsiness air conditioning system of this embodiment is automatically turned on, thereby alleviating or helping the driver overcome the fatigue state.

[0045] Embodiment 2

[0046] This embodiment is based on the working method of the driver anti-drowsiness air conditioning system described in Embodiment 1, including the following steps:

[0047] When the driver is driving fatigued, the driver's anti-drowsiness air conditioning system is actively turned on or the monitoring device starts, the cold air supply device starts working, and the cooled cold air is blown to the driver's head through the air outlet. The air collecting vent sends the cold air back to the cold air supply device, and the cold air supply device cools the air again and sends it out, and the cycle continues to keep the temperature of the driver's head space at a relatively low level, thereby achieving the purpose of keeping the driver awake while driving.

[0048] Multiple working modes can be set according to the opening of different types of air outlets. The working modes include normal blowing mode, directional blowing mode and strong blowing mode. Normal blowing mode only opens horizontal air outlet 2 and vertical air outlet 3, directional blowing mode only opens circular air outlet 1, and strong blowing mode opens all air outlets.

[0049] The specific working modes of the conventional blowing mode, directional blowing mode and strong blowing mode are briefly introduced below.

[0050] Conventional blowing mode: When the driver is in a fatigue driving state, the driver's anti-drowsiness air conditioning system can be started by actively opening or monitoring the device. If the conventional blowing mode is selected, the air compressor 9 starts the air conditioning cooling work after receiving the working signal, and passes through the third connecting pipe 12 through the fourth connecting pipe 7 inside the main driver's seat cushion 11, and blows the cold air through the horizontal air outlet 2 and the vertical air outlet 3 to the driver's face. The circular 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 collecting ports on both sides of the main driver's seat headrest 6 under the suction of the air compressor 9 inside the main driver's seat back 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 cools the air again and sends it out, and the cycle continues to achieve the circulation to keep the temperature of the driver's head space at a relatively low state, so as to achieve the purpose of keeping the driver awake while driving.

[0051] Directional blowing mode: When the driver is in a fatigue driving state, the driver's anti-drowsiness air conditioning system can be started by actively opening or monitoring the device. If the directional blowing mode is selected, the air compressor 9 starts the air conditioning cooling work after receiving the working signal, and passes through the third connecting pipe 12 through the fourth connecting pipe 7 inside the main driver's seat cushion 11, and the cold air is blown to the driver's face through the circular hole air outlet 1. 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 at will through the circular hole air outlet 1, and can blow targetedly on the forehead, eyes, face, temples and other directional positions of the face to achieve the purpose of enhancing wakefulness. After the cold air passes through the driver's face, the cold air is collected through the air collecting ports on both sides of the driver's seat headrest 6 under the suction force of the air compressor 9 inside the main driver's seat back 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 cools the air again and then sends it out, and the cycle continues to keep the temperature of the driver's head space at a relatively low state, so as to achieve the purpose of keeping the driver sober while driving.

[0052] Strong blowing mode: When the driver is in a fatigue driving state, the driver's anti-drowsiness air conditioning system can be started by actively opening or monitoring the device. If the strong blowing mode is selected, the air compressor 9 starts the air conditioning cooling work after receiving the working signal, and the circular hole air outlet 1, the horizontal bar air outlet 2 and the vertical bar air outlet 3 baffles are all opened, and the third connecting pipe 12 passes through the fourth connecting pipe 7 inside the main driver's seat cushion 11, and the cold air passes through the circular hole air outlet, the horizontal air outlet 2, and the vertical air outlet 3 to blow on the driver's face. After the cold air passes through the driver's face, under the suction of the air compressor 9 inside the main driver's seat back 10, the cold air is collected through the air collecting ports on both sides of the main driver's seat headrest 6, 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 cools the air again and sends it out, and the cycle continues to achieve the circulation to keep the temperature of the driver's head space at a relatively low state. Under the effect of the strengthened cold air, the purpose of keeping the driver awake and driving is achieved, and driving safety is improved.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
