본 고안은 자동차 전조등 냉각장치에 관한 것이다.The present invention relates to a vehicle headlight cooling device.

전조등은 55W정도의 전구와 반사기, 베젤, 렌즈, 하우징 등으로 구성되며 내부가 먼지나 수분의 침투를 막기위해 밀폐되어 있고 점등시 필라멘트로부터 발생된 열이 대류 및 복사하여 내부온도를 상승시키고 있다.The headlight consists of a 55W bulb, reflector, bezel, lens, housing, etc., and the inside is sealed to prevent dust or moisture from infiltrating. The heat generated from the filament during condensation and radiation increases the internal temperature.

그러나 현재 시중에서는 규정된 전구(55W)가 아닌 100W전구의 부분별한 사용으로 인해 전조등의 멜팅(melting)현상 및 화재가 빈번히 일어나고 있는데 현재의 전조등 구조상 이를 방지하기는 불가능한 것이다.However, due to the partial use of the 100W bulb instead of the prescribed light bulb (55W) on the market, there is a frequent phenomenon of melting and fire of the headlight, it is impossible to prevent this in the current headlight structure.

본 고안의 목적은 전조등내에 강제 공기순환시켜 그 냉각효과로 전조등내의 베젤과 하우징, 렌즈 등을 용융점 이하로 낮추는데 있는 것이다.The object of the present invention is to force forced air circulation in the headlamp and to lower the bezel, the housing, and the lens in the headlamp below the melting point by the cooling effect.

본 고안은 상기 목적을 달성하기 위하여, 전조등 내로 흡기가능하고 공기흡입방향 조절이 가능한 송풍튜브를 갖는 2개의 분기통로를 형성하며 일측의 분기통로는 송풍모터로 흡기가능하게 하고 타측의 분기통로는 에어컨에 의한 흡기가 가능한 흡기덕트와, 전조등 외부로 배기가능하고 배기압조절가능한 압력밸브를 갖는 배기덕트와, 전조등 내부온도를 감지하는 온도센서 및 상기 온도 센서의 입력신호가 설정치 이상일 때 상기 송풍모터의 가동 또는 타측의 분기통로의 개방을 선택적으로 실행시키는 전자제어유니트로 구성시킨 것이다.In order to achieve the above object, the present invention forms two branch passages having a blower tube that is intakeable into the headlamp and the air suction direction is adjustable, and the branch passage of one side enables the intake of the blower motor and the branch passage of the other side of the air conditioner. Intake duct capable of intake by the air, an exhaust duct having a pressure valve capable of evacuating the outside of the headlight, and an exhaust pressure control valve, a temperature sensor for detecting the internal temperature of the headlight, and an input signal of the temperature sensor of the blower motor when It is composed of an electronic control unit that selectively executes operation or opens the branch passage on the other side.

이하 본 고안을 실시예 도면에 의하여 설명한다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

제1도는 본 고안의 전체구성을 나타낸 것으로서, 벌브(1)를 갖는 반사기(2), 하우징(3)과 베절(4) 및 렌즈(5)로 이루어진 전조등에 있어서 하우징(3)후방 하부와 반사기(2)간에 흡기덕트(6)가 설치되고, 하우징(3)상부와 반사기(2)간에 배기덕트(7)가 설치된 것이다.FIG. 1 shows the overall configuration of the present invention, in which a reflector 2 having a bulb 1, a housing 3, a section 4 and a lens 5, the lower part of the rear of the housing 3 and the reflector The intake duct 6 is provided between (2), and the exhaust duct 7 is provided between the upper part of the housing 3 and the reflector 2. As shown in FIG.

흡기덕트(6)는 하우징(3)외부에서 2개의 분기통로(8,8')로 갈려진다. 분기통로(8,8')내에는 제4도와 같이 공기가 흡입될 때 중앙부가 팽창하고 공기가 흡입되지 않는 쪽은 상대적으로 그 흡입압에 의하여 중앙부가 수측되는 송풍튜브(9,9')가 설치된다.The intake duct 6 is divided into two branch passages 8, 8 ′ outside the housing 3. In the branch passages 8 and 8 ', the blower tubes 9 and 9', in which the central portion expands when air is sucked in and the air is not sucked in, are relatively water-received by the suction pressure. Is installed.

이러한 분기통로(8,8')중 일측의 분기통로(8)에는 송풍모터(10)를 설치하여 필요시 외기를 분기통로(8)내로 공급하도록 하고 있고, 타측의 분기통로(8')에는 차량에 기존 설치되는 에어컨의 덕트와 연결된다.The blower motor 10 is installed in the branch passage 8 on one side of the branch passages 8 and 8 'so as to supply outside air into the branch passage 8 if necessary, and in the branch passage 8' on the other side. It is connected to the air duct of the existing air conditioner installed in the vehicle.

이 경우 기존 에어컨 덕트에서 상기 타측의 분기통로(8')로 냉기를 보낼 수 있도록 개폐되는 솔레노이드 밸브설치의 도어(미도시)가 설치되어야 한다.In this case, a door (not shown) of a solenoid valve installation that opens and closes to send cold air from the existing air conditioner duct to the branch passage 8 'on the other side should be installed.

배기덕트(7)내에는 제2도 및 제3도에 도시하는 바와 같은 압력밸브(11)가 설치된다. 이 압력밸브(11)는 중앙에 밸브체(12)가 끼워져 있어 일정압력이 작용하면 밸브체(12)가 상향으로 부상하여 중앙의 개방되는 통로를 통하여 반시기(2)내부의 열기를 밖으로 배출하도록 한 것이다.In the exhaust duct 7, a pressure valve 11 as shown in FIGS. 2 and 3 is provided. The pressure valve 11 has a valve body 12 fitted in the center thereof, and when a constant pressure is applied, the valve body 12 rises upward and discharges heat from the inside of the semi-period 2 through a passage that is open at the center. I did it.

상기 배기덕트(7)의 입구측에는 온도센서(13)가 부착되어 반사기(2)내부온도를 감지한다. 이 온도센서(13)는 신호변환되어 전자제어유니트(14)에 신호입력되도록 하고 있고, 전자제어유니트(14)는 상기 온도센서(13)외에 에어컨의 가동유무를 판단하기 위한 신호가 입력된다.A temperature sensor 13 is attached to the inlet side of the exhaust duct 7 to sense the temperature inside the reflector 2. The temperature sensor 13 is signal-converted so that a signal is input to the electronic control unit 14, and the electronic control unit 14 receives a signal for determining whether the air conditioner is operating in addition to the temperature sensor 13.

전자제어유니트(14)의 출력단에서 상기한 에어컨덕트에서 타측의 분기통로로 냉기를 공급하기 위한 도어의 도어 소레노이드 밸브와 송풍모터(10)가 연결되어 신호변환된 상태로 출력하도록 하고 있다. 또 전자제어유니트(14)의 출력온도조건은 렌즈(5)와 베젤(4)의 멜팅온도 t에서 약 15°낮은 온도를 설정치로 한다. 따라서 이러한 전자제어유니트(14)의 알고리즘과 결부된 본 고안의 동작순서를 제5도의 스텝으로 설명한다.At the output end of the electronic control unit 14, the door solenoid valve of the door for supplying cold air to the branch passage on the other side from the air conditioner duct and the blower motor 10 are connected and output in a signal converted state. The output temperature condition of the electronic control unit 14 is set to a temperature lower by about 15 ° from the melting temperature t of the lens 5 and the bezel 4. Therefore, the operation procedure of the present invention associated with the algorithm of the electronic control unit 14 will be described with the steps of FIG.

먼저, 전조등을 점등시키면(S21) 온도센서(13)에 따른 전도등 내부온도를 감지한다(S22). 다음 스템 S23에서 설정치에 도달했는가를 판단하여 부정이면 복귀(초기화)하고 긍정이면 스텝 S24에서 다시 에어컨이 가동되고 있는가를 판단하여 에어컨이 가동중이면 도어 솔레노이드 밸브를 작동(S25)시키고 그렇지 않으면 송풍모터(10)를 구동(S26)시켜 분기통로(8,8')의 어느 일측으로 공기가 유입되도록 한다.First, when the headlights are turned on (S21), the internal temperature of the conduction lamp according to the temperature sensor 13 is sensed (S22). It is judged whether the set value is reached in the next stem S23, and if it is negative, it returns (initializes). If it is positive, it is determined whether the air conditioner is operating again in step S24. If the air conditioner is operating, the door solenoid valve is operated (S25). 10) to drive (S26) to allow air to flow into either side of the branch passage (8,8 ').

제4도는 일측의 분기통로(8)로 송풍모터(10)에 의한 외기의 유입상태를 도시한 것으로, 이 유입되는 공기압에 의하여 일측의 분기통로(8)내에 있는 송풍튜브(9)는 팽창되고 반대로 타측의 분기통로(8')내에 있는 송풍튜브(9')는 그 공기압에 의하여 수측되어 유입되는 외기가 반사기(2)내로만 공급하게 된다. 따라서 반사기(2)내로 들어온 외기는 벌브(1)에서 발생되는 열기와 혼합되어 압력밸브(11)의 밸브체(12)를 밀고 배기덕트(7)를 통해 외부로 배출하게 되는 것이다.4 shows an inflow state of the outside air by the blowing motor 10 into the branch passage 8 on one side, and the blowing tube 9 in the branch passage 8 on the one side is expanded by the air pressure introduced therein. On the contrary, the blower tube 9 'in the branch passage 8' on the other side is supplied by the air pressure into the reflector 2 only through the outside air. Therefore, the outside air introduced into the reflector 2 is mixed with the heat generated from the bulb 1 to push the valve body 12 of the pressure valve 11 and discharge it to the outside through the exhaust duct 7.

이와 같은 본 고안은 공기를 전조등내에 강제순환시켜 일정온도 이하로 냉각시켜 주므로 베젤과 하우징 및 렌즈 등이 멜팅되지 않아 전조등의 수명연장 및 안전사고의 예방에 기여하게 되는 것이다.The present invention is forced to circulate the air in the headlamp to cool below a certain temperature, so that the bezel, the housing and the lens is not melted to contribute to the extension of the life of the headlamp and prevention of safety accidents.
