[Objective of the invention]

The present invention can prevent drowsiness of the driver by preventing contaminated exhaust gas, etc., to prevent drowsiness of the driver, as well as help driving safely, and maintain a comfortable indoor air to help the health of the driver and passengers. The purpose is to provide an internal and external air switching device.

[Technical Field to which the Invention belongs and Conventional Technology in the Field]

The present invention relates to an internal and external air switching device of a vehicle, and more particularly, by measuring the distance with the front vehicle through the inter-vehicle distance sensor and automatically switching to the bet if it is determined to be close to the front vehicle within a certain distance. After a certain distance, it is invented so that the polluted exhaust gas can be prevented from entering the room by returning to the original air again.

Conventionally, the ventilation device of a vehicle has a configuration in which outside air is introduced or internal air is circulated only when a driver directly selects and operates an indoor and outdoor air switching switch installed in a control panel.

That is, when the driver directly operates the outdoor unit switching switch installed in the control panel, the door installed in the air inlet duct opens, and the internal / external air switching motor forcibly absorbs the outside air of the vehicle, and when the indoor unit switching switch is operated, the door in the air inlet duct is operated. As the door is closed, the internal / external air switching motor sucks the internal air and blows it back.

Technical Field of the Invention

In such a configuration, the door in the air inlet duct is opened and closed to inflow and circulate the outdoor and indoor air only by the operator operating one of the outdoor unit switching switch and the indoor unit switching switch.

However, when driving in the city, congestion frequently occurs, the distance from the vehicle in front is often close. In this case, when the outdoor unit switching switch is operated so that outdoor air is introduced, a part of the gas exhausted from the vehicle in the front is introduced into the room. .

Therefore, when the exhaust gas of the front car is introduced into the room as described above, the driver should operate the indoor unit changeover switch to block the outside polluted air from entering the room. There is a problem that comes with a lot of convenience in operating the indoor, outdoor air switch.

Composition and Action of the Invention

An object of the present invention described above is installed in the front bumper portion of the vehicle, the distance detection sensor for detecting the distance with the front vehicle as an electrical signal, and the distance detection signal with the front vehicle input from the inter-vehicle sensor is within a certain distance The control unit detects recognition and turns on the indoor unit switching switch of the control panel unit within a predetermined distance, and turns on the outdoor unit switching switch when the predetermined distance is exceeded, and is installed in the control panel of the vehicle and selectively operated by a driver, When the output signal is generated, the internal / external air switching switch which is turned on / off first and the indoor air or outdoor air switching switch forcibly introduces outdoor air or circulates indoor air in response to which of the indoor and outdoor air switching switches is turned on. The drive phase of the external air switching motor, the seal and internal and external air switch, and the internal and external air switching motor In response to heating and cooling and the outdoor air and the room air it can be achieved by configuring the auto air conditioning amplifier to blow into the room.

Therefore, the driver automatically responds to the distance to the vehicle in front of the vehicle, regardless of the distance from the vehicle in front, so that outdoor air or indoor air is circulated. Safety accidents caused by sleepiness can be prevented in advance, as well as the indoor environment can be kept comfortable, which can help maintain the health of passengers including drivers.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a partial side view of a vehicle showing a state of measuring a distance between vehicles in an apparatus to which the present invention is applied, and FIG. 2 is a block diagram of the apparatus of the present invention.

According to this, the inter-vehicle distance sensor 1 is installed on the front bumper 6 of the vehicle to detect the distance with the front vehicle as an electrical signal, and the distance detection signal with the front vehicle input from the inter-vehicle sensor 1. Control unit 2 for detecting whether the switch is within a predetermined distance and turning on the indoor unit switching switch 31 of the control panel 3 when the predetermined distance is within a predetermined distance, and turning on the outdoor unit switching switch 32 when the predetermined distance is over the predetermined distance. Installed on the panel 3 and selectively turned on / off by the driver, and when a predetermined output signal is generated from the control unit 2, the on / off switching switches 31 and 32 And internal / external air switching motors 4 for forcibly introducing outdoor air or circulating indoor air in response to which of the indoor unit and outdoor unit switching switches 31 and 32 are turned on. Selector switch (31,32) In, in response to the driving state of the outside switching motor (4) to cool and heat the outdoor air and the room air is characterized in that configured in the auto air conditioning amplifier 5 that blows out into the room.

In the apparatus of the present invention configured as described above, first, the interior and exterior air changeover switches 31 and 32 installed on the control panel 3 at one side of the driver's front face are selectively turned on and off by the driver in the usual manner as in a conventional vehicle. In response to the output of the inter-vehicle distance sensor 1, when a predetermined output signal is generated in the control unit 2 that generates a predetermined output signal, the on / off is prioritized.

In addition, the inter-vehicle distance sensor 1 installed in the front bumper 6 of the vehicle continuously detects the distance to the front vehicle while driving the vehicle as an electrical signal and outputs it to the control unit 2, so that the control unit 2 ) Compares the distance detection signal with the preceding vehicle input from the inter-vehicle sensor 1 with the reference distance value stored in the vehicle body.

As a result, when it is determined that the distance between the vehicle ahead is within a certain distance, the indoor unit switching switch 31 of the control panel 3 is turned on (of course, the indoor unit switching switch 31 is already in the on state by the driver). When the outdoor unit switching switch 32 is turned on, it is turned off and the indoor unit switching switch 31 is turned on. To do that.

In addition, if the controller 2 detects the distance between the vehicle and the vehicle, the indoor unit selector switch 31 is turned off and the outdoor unit selector switch 32 is turned on (that is, if it is out of the predetermined distance). The internal and external air switching motor 4 forcibly sucks the outside air.

Meanwhile, the auto air conditioner amplifier 5 cools and heats the outdoor air or the indoor air in response to a driving state of the real and internal air switching switches 31 and 32 and the internal and external air switching motors 4. To be blown.

[Effects of the Invention]

As described above, according to the present invention, even if the driver does not operate the indoor and outdoor air switching switches at all, the outdoor air is automatically introduced or the indoor air is circulated in response to the distance to the front car, thereby bringing the car closer to the front car. Therefore, it is possible to prevent the polluted exhaust gas from entering the room, which prevents the driver from inhaling the polluted air and makes him sleepy, and keeps the indoor environment pleasant. It is very useful invention that can help to maintain the health of passengers, including.
