Description
본 발명은 차량용 헤드램프에 관한 것으로서, 더욱 상세하게는 하이 빔의 on/off 신호에 의한 엑츄에이터의 솔레노이드 작동으로 실드(shield)부의 빛 차단 위치를 가변시키는 방식으로 이루어진 헤드램프를 제공함으로써, 하나의 벌브로 하이 빔과 로우 빔을 동시에 만족시킬 수 있는 차량용 헤드램프에 관한 것이다.The present invention relates to a headlamp for a vehicle, and more particularly, by providing a headlamp made of a method of changing a light blocking position of a shield by solenoid operation of an actuator by an on / off signal of a high beam. The present invention relates to a vehicle headlamp capable of satisfying a high beam and a low beam simultaneously with a bulb.
자동차가 주행중일 때 야간조명 이외에는 신호 및 표식 등의 기능이 필요하다.When the car is driving, functions such as signals and signs other than night lights are required.
조명장치는 헤드램프(head lamp), 포그램프(fog lamp), 턴시그널램프(turn signal lamp),스톱램프(stop lamp), 테일램프(tail lamp), 번호등이 있다.Lighting devices include a head lamp (fog lamp), a turn signal lamp (turn signal lamp), a stop lamp (tail lamp), a tail lamp (number lamp), and the like.
이중의 헤드램프는 야간주행중 안전을 유지하기 위한 충분한 거리에서 전방의 장애물을 확인할 수 있어야 하며, 다른 자동차에도 존재를 인지할 수 있도록 조도를 갖추어야 한다.Dual headlamps should be able to identify obstacles ahead of them at a sufficient distance to maintain safety while driving at night, and should be illuminated to recognize their presence in other vehicles.
또한, 어느 정도의 빛이 확산되어 주위의 상태를 파악할 수 있도록 해야되고, 주행중 교행할 때 대향차에 눈부심 등 운전에 방해를 주지 않도록 해야 한다.In addition, a certain amount of light must be diffused so that the surrounding conditions can be grasped, and when driving while driving, it must not interfere with driving such as glare on the opposite vehicle.
또한, 승차 또는 적재 하중에 의하여 광축이 변화되어 조명 효과를 저하시키지 않도록 해야 한다.In addition, it is necessary to prevent the optical axis from being changed by riding or loading loads so as to lower the lighting effect.
이러한 헤드램프는 고속주행에 따라 광도가 높고 빛의 확산각도가 넓은 헤드램프가 요구되어 1등당 광도는 주행 빔의 경우 15000~75000cd 이하(4등식의 경우 1200~75000cd)이고 변환빔은 3000~45000cd 이하로 규정되어 있다.These headlamps are required to have high brightness and high light diffusing headlamps due to high-speed driving. The brightness per 1 light is 15000 ~ 75000cd or less for driving beams (1200 ~ 75000cd for 4 lamps) and 3000 ~ 45000cd for converting beams. It is prescribed as follows.
한편, 헤드램프는 필라멘트가 진로 전방을 조명하는 주행빔용 필라멘트와, 대향차와 교행할 때 대향차에 눈이 부시지 않도록 감광 또는 하향이 되는 변환빔용 필라멘트가 있다.On the other hand, the headlamp has a filament for the running beam that the filament illuminates the front of the path, and the conversion beam filament that is exposed or downward so as not to dazzle the opposite car when crossing the opposite car.
이들의 필라멘트를 1개의 램프 유닛 내에 넣은 것을 좌우에 각각 1개씩 설치한 2등식, 각각의 필라멘트를 별도의 램프 유닛에 내장시켜 변환용 유닛을 좌우 1개씩 설치하고 주행용 유닛을 좌우 1개씩 설치한 4등식이 있다.Two lamps each of these filaments placed in one lamp unit on each side, each filament is built into a separate lamp unit, one conversion unit is installed on the left and one driving unit on the left and right There is a quadratic equation.
도 3은 종래 발명에 따른 차량용 헤드램프의 작동 구조를 도시한 단면도이다.3 is a cross-sectional view showing an operation structure of a vehicle headlamp according to the related art.
현재 적용중인 프로젝션 타입(projection type)의 헤드램프는 하나의 벌브(2)를 사용하여 로우 빔 혹은 하이 빔만으로 사용하는 구조로 되어 있다.Projection type headlamps currently applied have a structure in which only one bulb 2 is used for low beam or high beam.
첨부한 도 3은 로우 빔 프로젝션 타입의 헤드램프 구조로서, 로우 빔의 빛은 실드(10)에서 차단하지 않고 상향하는 빛만 실드(10)가 차단하여 로우 빔만 작동 시키는 헤드램프 구조이다.3 is a head beam structure of a low beam projection type, in which the light of the low beam is not blocked by the shield 10, and only the upward light is blocked by the shield 10 to operate only the low beam.
상기와 같은 구조는 로우 빔만 적용되어 별도의 하이 빔 헤드램프를 설치해야함으로 4등식 헤드램프는 엔진룸의 설계상 불리하고 디자인 자유도가 떨어질 뿐만 아니라 원가도 상승된다.Since the above structure requires only a low beam to install a separate high beam headlamp, the quadruple headlamp is disadvantageous due to the design of the engine room and the design freedom is lowered and the cost is increased.
한편, HID(high intensity discharge head lamp) 적용시 시스템이 고가임으로 로우 빔만 HID를 적용하고 하이 빔은 기존 할로겐 벌브를 사용하여서, 하이 빔의 on 상태는 상대적으로 로우 빔보다 어두워 보이는 문제점이 발생하였다.On the other hand, when applying the high intensity discharge head lamp (HID) system is expensive, only the low beam HID is applied and the high beam using a conventional halogen bulb, the on state of the high beam is relatively darker than the low beam has occurred.
따라서, 본 발명은 상기와 같은 기존의 문제점을 해결하고자 한 것으로서, 하이 빔의 on/off 신호에 의해 엑츄에이터의 솔레노이드가 작동하여 에이밍 로드(aiming rod)가 전후방으로 이동함에 따라 피봇을 중심으로 실드(shield)가 움직이며 하이 빔과 로우 빔이 조절됨으로써, 한 개의 벌브(bulb)로 로우 빔, 하이 빔을 동시에 만족시켜며, HID(high intensity discharge head lamp) 헤드램프 적용시 하이 빔도 HID 헤드램프 적용 가능한 구조로 엔진룸 설계상 유리하며 원가도 절감할 수 있고 설계 자유도를 높일 수 있는 차량용 헤드램프를 제공하는데 그 목적이 있다.Accordingly, the present invention is to solve the above-described problems, the solenoid of the actuator by the on / off signal of the high beam to operate the shielding around the pivot as the moving rod (aiming rod) moves forward and backward As the shield moves and the high beam and the low beam are adjusted, a single bulb can satisfy both the low beam and the high beam, and the high beam is also HID head when the high intensity discharge head lamp (HID) headlamp is applied. It is an object of the present invention to provide a headlamp for a vehicle that can be advantageous in designing an engine room, reduce costs, and increase design freedom.

또한, 상기 헤드램프는 HID 헤드램프 적용이 가능한 것을 특징으로 한다.In addition, the headlamp is characterized in that the HID headlamp can be applied.
이하, 첨부도면을 참조하여 본 발명을 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 차량용 헤드램프의 로우 빔 작동 상태를 도시한 단면도이고, 도 2는 본 발명에 따른 차량용 헤드램프의 하이 빔 작동 상태를 도시한 단면도이다.1 is a cross-sectional view showing a low beam operating state of a vehicle headlamp according to the present invention, Figure 2 is a cross-sectional view showing a high beam operating state of a vehicle headlamp according to the present invention.
도 1, 도 2에서 도시한 바와 같이, 본 발명에 따른 실드부(11)는 하이 빔의 on/off 신호에 따라 엑츄에이터(4)에 의해 전후로 구동되는 에이밍 로드(6)의 선단에 회동 가능하게 피봇(8)으로 체결되어 있다.As shown in Figs. 1 and 2, the shield part 11 according to the present invention can be rotated at the tip of the aming rod 6 driven back and forth by the actuator 4 according to the high beam on / off signal. It is fastened to the pivot (8).
한편, 상기 엑츄에이터(4)는 헤드램프 하단의 차체 패널 일 측에 체결되어 고정되어 있다.On the other hand, the actuator 4 is fastened and fixed to one side of the body panel of the lower headlamp.
또한, 상기 엑츄에이터(4)에는 솔레노이드를 적용하였다.In addition, a solenoid was applied to the actuator 4.
상기 실드부(11)는 지지체(10a) 상단에 형성되어 있는 원형의 회전중심체(10b)와, 헤드램프의 빛을 차단하는 본체(10)가 일체형으로 형성되어 있다.The shield portion 11 is formed of an integral body of a circular rotation center (10b) formed on the upper end of the support (10a) and the main body 10 for blocking the light of the head lamp.
상기 원형의 회전중심체(10b)는 회동 가능하게 힌지(10c)로서 체결되고, 지지단의 구면홈에 안착되는 동시에 밀착되어 지지단(12)에 지지된다.The circular rotating center body 10b is rotatably fastened as a hinge 10c, is seated in a spherical groove of the support end, and is closely attached to and supported by the support end 12.
따라서, 상기 실드부(11)는 헤드램프 하단에서 회전중심체(10b)를 축으로 회전하며 헤드램프의 빛을 선택적으로 차단할 수 있다.Therefore, the shield part 11 may rotate the rotation center body 10b in the axis at the lower end of the headlamp and selectively block light of the headlamp.
한편, 상기 실드부(11)의 본체(10)는 종래 헤드램프의 실드부(100)와 같은 역할을 한다. 즉 실드부(11)의 지지체(10a)와 일체형으로 형성되어 있는 본체(10)는 소정의 길이를 가짐으로써 헤드램프의 상향으로 나오는 빛을 선택적으로 오픈 시킬 수 있다.On the other hand, the main body 10 of the shield portion 11 serves the same as the shield portion 100 of the conventional head lamp. That is, the main body 10 formed integrally with the support 10a of the shield portion 11 may selectively open the light emitted upward of the head lamp by having a predetermined length.
따라서, 상기와 같은 구조는 하나의 벌브(2)만으로도 헤드램프의 하이 빔과 로우 빔의 조사를 가능하게 한다.Therefore, such a structure enables the irradiation of the high beam and the low beam of the headlamp with only one bulb 2.
도 1 에서 도시한 바와 같이, 로우 빔 작동상태일때는 에이밍 로드(6)가 엑츄에이터(4) 내부로 삽입되어 있다. 따라서 상기 에이밍 로드(6)와 체결되어 있는 실드부(10)는 지지단(12)에 지지되어 상향하는 빛을 차단하게 된다.As shown in FIG. 1, the aming rod 6 is inserted into the actuator 4 in the low beam operation state. Therefore, the shield part 10 coupled to the aming rod 6 is supported by the support end 12 to block the upward light.
이처럼 상향하는 빛만 실드가 차단하여 로우 빔만 작동시키는 구조로 일반적인 주행 상태의 헤드램프 작동 구조이다.As such, the shield blocks only upward light and operates only the low beam, which is a headlamp operation structure in a general driving state.
도 2에서 도시한 바와 같이, 하이 빔 작동상태일때는 하이 빔 on 신호에 의해서 엑츄에이터(4)의 솔레노이드가 작동하여 에이밍 로드(6)를 전방으로 이동시킨다.As shown in FIG. 2, the solenoid of the actuator 4 is operated by the high beam on signal to move the aiming rod 6 in the high beam operation state.
따라서, 상기 에이밍 로드(6)와 체결되어 있는 실드부(10)가 피봇을 중심으로 지지단(12)에 지지된 상태에서 뒤쪽으로 회전하게 된다.Therefore, the shield part 10 which is engaged with the aiming rod 6 is rotated backward while being supported by the support end 12 about the pivot.
따라서, 상향하는 빛을 차단하고 있던 실드부(10)가 뒤쪽으로 젖혀짐으로써 벌브(2)의 상향하는 빛이 오픈 되어 하이 빔 작동이 되는 구조이다.Therefore, the shield part 10 which blocks the upward light is flipped backward, so that the upward light of the bulb 2 is opened to perform high beam operation.
한편, 하이 빔 off 신호가 나오면 상기 장치는 역으로 작동하여 로우 빔 작동 구조로 돌아오게 된다.On the other hand, when the high beam off signal is issued, the device operates in reverse to return to the low beam operating structure.
한편, 상기와 같은 헤드램프에 현재 적용중인 HID 램프 적용시 하이 빔도 HID 헤드램프의 적용이 가능한 구조로서 엔진룸의 설계상 유리하며 원가를 절감되며 설계 자유도를 높일 수 있다.On the other hand, when the HID lamp is currently applied to the headlamp as described above, the high beam can also be applied to the HID headlamp structure, which is advantageous in the design of the engine room and can reduce the cost and increase the design freedom.
이상에서 본 바와 같이, 본 발명에 따른 차량용 헤드램프에 의하면, 하이 빔의 on/off 신호에 의해 엑츄에이터의 솔레노이드가 작동하여 에이밍 로드가 전후방으로 이동함에 따라 피봇을 중심으로 실드가 움직이며 하이 빔과 로우 빔을 조절함으로써, 한 개의 벌브로 로우 빔, 하이 빔을 동시에 만족시킬 수 있으며, HID 헤드램프 적용시 하이 빔도 HID 헤드램프 적용 가능한 구조로 엔진룸 설계상 유리하다.As described above, according to the headlamp for a vehicle according to the present invention, the solenoid of the actuator is activated by the on / off signal of the high beam, the shield moves around the pivot as the aiming rod moves forward and backward. By controlling the and low beams, one bulb can satisfy both low and high beams, and HID headlamps can be applied to HID headlamps.
또한, 간단한 구조로 부품 및 공정을 축소하여 원가를 절감할 수 있다.In addition, the cost can be reduced by reducing parts and processes with a simple structure.
