본 고안은 자동차의 내외기 절환장치에 관한 것으로, 특히 구동모토로 회전되는 차단판을 산소감지센서의 신호에 따라 회전 작동되도록 외기 유입구에 설치함으로써, 시내 주행시 배기 가스에 의한 외기의 나쁜 상태를 산소감지센서로 판별하여 외기가 자동 차단되기 때문에 운전자 및 다른 탑승자들의 인체에 해를 끼치는 것이 예방되는 자동차의 산소감지센서를 갖는 내외기 절환장치에 관한 것이다.The present invention relates to an internal and external air switching device of a vehicle, and in particular, by installing a blocking plate rotated by a driving motor at an external air inlet so as to be rotated in response to a signal of an oxygen sensor, oxygen of bad air caused by exhaust gas during city driving is provided. The present invention relates to an internal / external air switching device having an oxygen detection sensor of a vehicle, in which outdoor air is automatically cut off by a detection sensor, thereby preventing harm to a human body of a driver and other passengers.

일반적으로 자동차에 탑승한 사람들은 모든 기후와 주행 조건에서 쾌적한 환경을 갖게 하고, 또한 유리창이 흐리거나 서리가 끼는 것을 방지하고 차실내에 상쾌하면서 깨끗한 공기가 순환되도록 하여 항상 안전한 운전 조건을 제공해주게 된다.In general, people in a car have a pleasant environment in all weather and driving conditions, and also prevent the windows from becoming cloudy or frosted, and provide fresh and clean air circulation in the cabin to provide safe driving conditions at all times. .

종래 차실내로 내외기를 공급하는 과정에 있어서, 첨부된 도면 제1도에 도시된 바와같이 외기를 차실내에 공급하여 차실내를 환기시키고자 할 때에는 수동으로 조작되는 차단판(3)을 작동시켜 내부유입구(1)를 차단하고, 외기 유입구(2)를 개방시켜서 외기를 덕트(4)로 유도한 다음, 모터(5)를 구동시켜 송풍팬(5a)이 회전되게 하여 외기를 강제로 송풍시키게 된다.In the process of supplying the interior and exterior air into the conventional vehicle interior, as shown in Figure 1 of the accompanying drawings to supply the outside air to the interior of the vehicle to ventilate the interior by operating the blocking plate (3) manually operated Shut off the inlet 1, open the outside air inlet 2 to guide the outside air to the duct 4, and then drive the motor 5 so that the blowing fan 5a is rotated to force the outside air to blow. do.

한편, 송풍기(5a)에 의해 강제적으로 송풍된 외기는 덕트(4)를 지나 히터장치(6)의 라디에이터(6a)에서 필요한 만큼 덮혀지거나 혹은 그 상태 그대로 실내토출구(7)를 통해 실내로 공급된다.On the other hand, the outside air forcibly blown by the blower 5a is covered by the radiator 6a of the heater device 6 through the duct 4 as necessary or supplied to the room through the indoor discharge port 7 as it is. .

그리고 실내 공기만으로 공기를 순환시키고자 할 때에는 수동으로 차단판(3)을 동작시켜 외기 유입구(2)를 차단한 후 내부유입구(1)에서 흡입된 공기가 덕트(4)를 통해 앞서 기술된 경로로 실내토출구(7)에 공급되도록 한다.When the air is to be circulated only by the indoor air, the blocking plate 3 is manually operated to block the outside air inlet 2, and then the air sucked in the internal inlet 1 passes through the duct 4. It is to be supplied to the indoor discharge port (7).

그런데 종래에는 차단판(3)을 수동으로 조작하여 필요에 따라 내외기 손환량을 결정했기 때문에 차단판(3)을 개방하여 외기 유입구(2)로 외기를 흡입하게 되었다.However, in the related art, since the internal and external air loss was determined as needed by manually operating the blocking plate 3, the blocking plate 3 was opened to suck the outside air into the outside air inlet 2.

시내 주행을 할 경우 많은 차량에서 배출되는 배기 가스가 다량으로 배출되는 관계로 배기 가스가 외기 유입구(2)를 통해 차실내에 유입되었다.When driving in the city, the exhaust gas is discharged from a large number of vehicles, the exhaust gas is introduced into the cabin through the outside air inlet (2).

이때 운전자는 유입된 배기 가스를 후각으로 감지한 후 차단판(3)으로 외기 유입구(2)를 차단하여 외기의 유입을 정지시키게 되지만, 이미 차실내에는 배기 가스가 유입된 상태에 있으므로, 운전자 및 탑승자들이 인체에 해를 끼치게 되는 등의 문제점이 발생했었다.At this time, the driver senses the introduced exhaust gas by the sense of smell and stops the inflow of outside air by blocking the outside air inlet 2 with the blocking plate 3, but since the exhaust gas is already in the interior of the vehicle, the driver and Problems such as the passengers to harm the human body had occurred.

본 고안은 이러한 점을 감안하여 안출한 것으로서, 외기가 유입되는 유입구에 산소 함유량이 감지되는 센서를 설치한 후 그 센서에 의해 차실내로 유입되는 외기의 오염도를 파악함으로써, 기준치 이상의 산소를 포함하지 않을 경우 외기 유입구를 자동적으로 차단시켜 보다 쾌적한 차내 환경을 이룰 수 있게 된 자동차의 산소감지센서를 갖는 내외기 절환장치에 관한 것이다.The present invention has been devised in view of this point, and by installing a sensor that detects the oxygen content at the inlet port through which the outside air is introduced, it grasps the degree of pollution of the outside air introduced into the vehicle interior by the sensor, so that it does not contain oxygen above the reference value. If not, the present invention relates to an internal and external air switching device having an oxygen sensor of an automobile, which automatically blocks the external air inlet to achieve a more comfortable interior of the vehicle.

이러한 본 고안의 목적은, 산소감지센서에 의해 감지된 신호로 구동모터의 구동량을 조절하게 된 마이컴을 설치하고, 외기 유입구와 내기 유입구 사이에 차단판을 회동 가능하게 설치한 자동차의 내외기 절환장치에 있어서, 상기 차단판의 회전축에 연결되어 차단판을 소정의 각도로 회전할 수 있도록 선단으로 기어부를 형성한 부채꼴기어와, 상기 부채꼴기어에 맞물려서 구동모터의 동력을 받아 부채꼴기어를 구동시키는 구동기어로 구성함으로써 달성되는 것이다.The object of the present invention is to install a microcomputer to adjust the driving amount of the drive motor with a signal sensed by the oxygen sensor, and to switch the internal and external air of the car to install a blocking plate between the outside air inlet and the inside air inlet An apparatus comprising: a fan gear which is connected to a rotating shaft of the block plate to form a gear part at the tip to rotate the block plate at a predetermined angle, and drives the fan gear by being driven by a driving motor by engaging the fan gear. This is achieved by configuring gears.

이하, 첨부도면에 의거하여 본 고안을 상세히 설명하도록 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

첨부된 도면 제3도 내지 제4도에 도시된 바와같이, 본 고안은 산소감지센서(10)에 의해 감지된 신호로 구도모터(40)의 구동량을 조절하게 된 마이컴(20)을 설치하고, 외기 유입구(90)과 내기 유입구(100) 사이에 차단판(80)을 회동 가능하게 설치한 자동차의 내외기 절환장치에 있어서, 상기 차단판(80)의 회전축(80a)에 연결되어 차단판(80)을 소정의 각도로 회전할 수 있도록 선단으로 기어부(72)를 형성한 부채꼴기어(70)와, 상기 부채꼴기어(70)에 맞물려서 구동모터(40)의 동력을 받아 부채꼴기어(70)를 구동시키는 구동기어(60)로 구성된 것이다.As shown in Figures 3 to 4 attached to the accompanying drawings, the present invention provides a microcomputer 20 to adjust the driving amount of the composition motor 40 by the signal detected by the oxygen sensor 10 In the internal / external air switching device of a vehicle in which the blocking plate 80 is rotatably installed between the outside air inlet 90 and the inside air inlet 100, the blocking plate 80 is connected to the rotary shaft 80a of the blocking plate 80. The fan-shaped gear 70 having the gear portion 72 formed at its tip to rotate the 80 at a predetermined angle, and the fan-shaped gear 70 by being driven by the driving motor 40 by being engaged with the fan-shaped gear 70. It is composed of a drive gear 60 for driving.

상기 부채꼴기어(70)에 형성된 기어부(72)의 양쪽 끝단에는 구동기어(6)의 이탈이 방지되도록 걸림턱(70a)을 각각 형성한다.Engaging jaws 70a are formed at both ends of the gear part 72 formed in the fan gear 70 to prevent the driving gear 6 from being separated.

또한 상기 산소감지센서(10)는 외기 유입구(70)에 직접 설치하거나 외부의 공기와 가장 빠르게 접촉될 수 있는 범퍼 부근에 설치하도록 한다.In addition, the oxygen sensor 10 is installed directly in the outside air inlet 70 or near the bumper that can be the fastest contact with the outside air.

이와같이 구성된 본 고안의 작용 효과를 보다 상세히 설명한다.The effect of the present invention configured as described above will be described in more detail.

우선, 내기유입구(100)를 차단판(80)으로 차단하여 외기 유입구(90)로 외기가 흡입되도록 하고, 그 흡입된 공기는 송풍기(120)를 구동시켜 송풍팬(120a)으로 외기가 덕트(110)를 통해 차실내에 지속적으로 공급되도록 강제 압송시키게 된다.First, the air inlet 100 is blocked by the blocking plate 80 to allow outside air to be sucked into the outside air inlet 90, and the sucked air drives the blower 120 to blow air into the air fan 120a. 110 is forcibly forced to be supplied to the vehicle interior.

이 상태에서 시내 주행의 경우 많은 차량에서 배출되는 배기 가스를 산소감지센서(10)로 감지하여 적절한 산소를 함유하지 않은 상태, 즉 공기가 오염되었을 경우 산소감지센서(10)에 의해 감지된 신호를 마이컴(20)으로 전달하게 되는 것이다.In this state, in the case of driving in the city, the exhaust gas emitted from many vehicles is detected by the oxygen sensor 10 so that it does not contain appropriate oxygen, that is, the signal detected by the oxygen sensor 10 when the air is contaminated Will be delivered to the microcomputer 20.

이어, 상기 마이컴(20)의 신호에 따라 구동모터(40)가 동작함에 따라 구동기어(60)도 함께 회전되므로, 이에 치합된 부채꼴 기어(70)와 회전축(80a)가 회전하게 된다.Subsequently, as the drive motor 40 operates in response to the signal of the microcomputer 20, the drive gear 60 also rotates together, such that the fan gear 70 and the rotating shaft 80a engaged thereto rotate.

이에 따라 차단판(80)이 회동되어 외기 유입구(90)를 차단시키게 되므로, 외기의 차내 유입을 차단할 수 있게 된다.Accordingly, the blocking plate 80 is rotated to block the outside air inlet 90, thereby preventing the inflow of outside air into the vehicle.

이러한 상태에서는 내기유입구(100)를 동해 차실내의 내기만으로 공기가 순환되는 것이다.In this state, the air is circulated only by the bet in the vehicle interior through the inlet 100.

또한 배기 가스가 많이 배출되는 지역을 벗어나게 되면, 산소감지센서(10)에서 감지된 산소 함유량의 신호를 마이컴(20)이 감지하여 구동모터(40)를 동작시키게 되고, 앞서와는 반대 방향으로 구동기어(60)와 부채꼴기어(70)를 각각 회동시켜 차단판(80)으로 외기 유입구(90)가 개방되게 함에 따라 외기를 차실내로 공급할 수 있는 상태로 한다.In addition, when the exhaust gas is discharged out of the region, the microcomputer 20 detects a signal of the oxygen content detected by the oxygen sensor 10 to operate the driving motor 40, and drive in the opposite direction as before. As the gear 60 and the fan gear 70 are rotated, the outside air inlet 90 is opened by the blocking plate 80, so that the outside air can be supplied into the vehicle interior.

이때, 상기 부채꼴 기어(70)와 구동기어(60)은 서로 치합된 상태이다.At this time, the fan gear 70 and the drive gear 60 is in a state of being engaged with each other.

즉, 구동기어(6)는 부채꼴 기어(70)를 회전시키게 되는 것이다.That is, the drive gear 6 is to rotate the fan gear 70.

여기서 상기 부채꼴기어(70)에는 걸림턱(70a)이 돌출 형성되어 있기 때문에 구동기어(60)이 치합된 부채꼴 기어(70)에서 이탈되는 것이 방지되는 것이다.In this case, since the locking jaw 70a protrudes from the fan gear 70, the driving gear 60 is prevented from being separated from the fan fan gear 70.

따라서 본 고안 자동차의 산소감지센서를 갖는 내외기 절환장치에 따르면, 자동차의 배기 가스가 많이 배출되는 지역, 즉 시내를 주행할 경우 외기의 오염 정도를 산소감지센서로 감지한 후 구동모터를 가동하여 차단판으로 외기 유입구를 자동적으로 차단함으로써, 오염된 외기가 차실내로 유입되지 않게 함에 따라 차실내의 운전자 및 탑승자가 보다 쾌적한 탑승감을 얻을 수 있게 된 고안이다.Therefore, according to the internal and external air switching device having the oxygen sensor of the present invention, when driving in the area where the exhaust gas of the car is discharged, that is, the city, the pollution of the outside air is detected by the oxygen sensor and then the drive motor is operated. By automatically blocking the outdoor air inlet with a blocking plate, contaminated outdoor air is not introduced into the cabin, and the driver and the passenger in the cabin can obtain a more comfortable riding feeling.
