본 발명은 고도 변화에 따른 자동차용 헤드램프 조사각 변동장치에 관한 것으로 더욱 상세히는, 고도계를 통해 주행중인 자동차의 고도 변화 데이타를 입력받아 변화율을 분선한 후 그에 따라 헤드램프의 조사각도가 자동으로 조절되도록 하는 방식을 통해, 운전자가 오르막길 또는 내리막길을 운전함에 있어서 보다 편안하게 시야를 확보한 상태에서 운전할 수 있도록 발명한 것이다.The present invention relates to a headlamp irradiation angle fluctuation device for an automobile according to an altitude change. More particularly, after the altitude change data of the driving vehicle is input through an altimeter, the change rate is divided and the headlamp irradiation angle is automatically adjusted accordingly. By adjusting the way, the driver can invent while driving uphill or downhill with a more comfortable view.

종래 대부분의 자동차용 헤드램는 수동으로 상하방향 조사각을 변동시키도록 구성되어 있고, 일부 자동차 관련 특허에서 헤드램프의 조사각이 스티어링 휠의 좌우 회전시 그에 부응하여 좌,우방향으로 조절되도록 하는 기술이 개제된 경우는 있다.Conventionally, most of the headlamps for automobiles are configured to manually change the vertical irradiation angle, and in some automobile patents, a technology in which the irradiation angle of the headlamp is adjusted in the left and right directions in response to the left and right rotation of the steering wheel. There is a case where this is listed.

즉, 운전자가 자동차의 야간 운전중 개부분 해두램프의 조사각을 수동으로 조절해 주어야만 하며, 일부 자동차에 실시되고 있는 자동 헤드램프 조사각 변경 시스템에 있어서는 좌,우방향의 조사각 변경만 가능하다.That is, the driver must manually adjust the irradiation angle of each part of the lamp during night driving of the vehicle, and in the automatic headlamp irradiation angle change system implemented in some vehicles, only the left and right irradiation angles can be changed. .

그런데, 종래 모든 자동차에 있어서 해드램프의 조사각이 상향 또는 하향으로 조절할 수 있는 기능은 구비되어 있지 않아 오르막길 또는 내리막길을 주행할 경우 불필요하게 헤드램프의 조사각이 하향 또는 상향으로 이루어지게 되어 전방시야 확보에 지장을 주는 문제점이 있다.However, in all conventional vehicles, the headlamp irradiation angle is unnecessarily adjusted when driving uphill or downhill because the headlamp irradiation angle is not provided to adjust upward or downward. There is a problem that impedes visibility.

본 발명은 이와같은 종래의 제반 문제점을 해결하기 위하여 안출된 것으로, 자동차내에 고도계를 설치하여 주행중 자동차의 고도 변화 데이타를 입력받아 변화율을 분선한 후 그에 따라 헤드램프의 조사각도가 자동으로 상,하향 조절되도록 하는 방식을 통해, 운전자가 오르막길 또는 내리막길을 운전함에 있어서도 보다 편안하게 시야를 확보한 상태에서 안전운전할 수행할 수 있는 고도 변화에 따른 자동차용 헤드램프 조사각 변동장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the above-mentioned conventional problems, install an altimeter in the car and divide the rate of change by receiving the altitude change data of the car while driving, and accordingly the irradiation angle of the headlamp automatically up and down By adjusting the method, the objective of the present invention is to provide a headlamp irradiation angle changer for an automobile according to an altitude change that enables a driver to drive safely while maintaining a more comfortable view even when driving uphill or downhill. have.

상기한 본 발명의 목적은, 자동차의 내부에 설치되어 주행중인 자동차의 고도를 전기적인 신호로 검출하는 고도계와; 상기 고도계의 출력신호를 입력받아 고도 변화율을 검출한 후 기 입력되어 있는 맵에 부응하는 출력신호를 모터 구동부에 출력시켜 주는 제어부와; 상기 제어부의 출력신호에 부응하여 상,하각 조절 모터를 정,역방향으로 정해진 회전수 만큼 회전시켜 주는 모터 구동부와; 상하부로 회동가능하게 축지되어 있는 헤드램프와 기어나 링크 등으로 연결되어 상기 모터 구동부의 출력신호에 부응하여 정방향 또는 역방향으로 구동되어 헤드램프의 빛 조사각이 상향 또는 하향으로 일정각도씩 고도 변화에 부응하여 변화되도록 하는 상,하각도 조절용 모터로 구성하므로써 달성할 수 있다.An object of the present invention as described above, the altimeter is installed in the interior of the vehicle for detecting the altitude of the driving vehicle as an electrical signal; A control unit which receives an output signal of the altimeter and detects a rate of change of altitude, and outputs an output signal corresponding to a previously input map to a motor driving unit; A motor driver for rotating the upper and lower angle regulating motors by a predetermined rotation speed in response to the output signal of the controller; It is connected to the headlamp, which is pivotally rotatable up and down, and is connected with gears or links, and is driven in the forward or reverse direction in response to the output signal of the motor driving unit so that the light irradiation angle of the headlamp is changed at a certain angle upward or downward. This can be achieved by configuring a motor for adjusting the upper and lower angles to change in response.

따라서, 헤드램프의 빛 조사각이 주행중인 자동차의 고도에 부응(즉, 경사각에 부응)하여 상방향 또는 하향방향으로 자동 조절되므로 운전자가 오르막길 또는 내리막길을 운전함에 있어서도 보다 편안하게 시야를 확보한 상태에서 안전운전을 수행할 수 있는 것이다.Therefore, the light irradiation angle of the headlamp is automatically adjusted in the upward or downward direction in response to the altitude of the driving vehicle (that is, in response to the inclination angle), so that the driver can more securely secure a view even when driving uphill or downhill. Safe operation can be performed in the state.

이에 따르면, 자동차의 내부에 설치되어 주행중인 자동차의 고도를 전기적인 신호로 검출하는 고도계(1)와;According to this, the altimeter (1) is installed in the interior of the vehicle for detecting the altitude of the driving car as an electrical signal;

상기 고도계(1)의 출력신호를 입력받아 소정 프로그램을 통해 고도 변화율을 검출하여 이를 기 입력되어 있는 맵에 대응시켜 소정의 제어신호를 모터 구동부(3)에 출력시켜 주는 제어부(2)와;A control unit (2) which receives the output signal of the altimeter (1) and detects the rate of change of altitude through a predetermined program and outputs a predetermined control signal to the motor driving unit (3) in correspondence with the previously input map;

상기 제어부(2)의 출력신호에 부응하여 상,하각 조절용 모터(4)를 정,역방향으로 정해진 회전수 만큼 구동시켜 주는 모터 구동부(3)와;A motor driver (3) for driving the upper and lower angle adjusting motors (4) by a predetermined number of revolutions in a forward and a reverse direction in response to an output signal of the controller (2);

상하부로 회동 가능하게 축지되어 있는 헤드램프(5)와 기어나 링크 등으로 연결된 형태로 설치되어 상기 모터 구동부(3)의 출력신호에 부응하여 정방향 또는 역방향으로 구동되어 헤드램프(5)의 빛 조사각이 상향 또는 하향으로 정해진 각도씩 고도 변화에 부응하여 변화되도록 하는 상,하각도 조절용 모터(4)로 구성한 것을 특징으로 한다.It is installed in the form connected to the head lamp (5) which is rotatably pivoted up and down and is connected by a gear or a link, and is driven in the forward or reverse direction in response to the output signal of the motor driver (3) to irradiate light of the head lamp (5). The angle is characterized by consisting of the upper and lower angle control motor (4) to change in response to the change in altitude by a predetermined angle up or down.

이와같이 구성된 본 발명 장치의 작용효과를 설명하면 다음과 같다.Referring to the operation and effect of the device of the present invention configured as described above are as follows.

먼저, 본 발명 장치가 실시된 헤드램프(5)는 종래와 달리 고정상태를 갖지 않코 도시 생략된 축을 중심으로 상하 방향으로 회동 가능한 상태임을 전제함은 물론 이와같은 축지 방법은 기 알려진 기술이므로 그 상세한 설명 및 도시를 생략 합니다.First, it is assumed that the headlamp 5 to which the present invention is implemented has a fixed state unlike a conventional state, and can be rotated in an up and down direction with respect to an omitted axis, as well as such a method of acquiring the battery. Omit the description and city.

한편, 제어부(2)에서는 자동차가 주행할시 자동차의 내부에 설치되어 있는 고도계(1)를 통해 주행중인 자동차의 고도 변화를 전기적인 신호로 계속 검출하여이를 소정 프로그램을 통해 고도 변화율을 검출하여 기 입력되어 있는 맵에 대응시켜 어떤 제어신호를 모터 구동부(3)에 출력시킬 것인지를 결정하게 된다.Meanwhile, the controller 2 continuously detects the altitude change of the car being driven by an electric signal through the altimeter 1 installed inside the car when the car is running, and detects the altitude change rate through a predetermined program. Corresponding to the input map, it is determined which control signal to output to the motor driver 3.

이때, 주행중인 자동차의 고도 변화가 예를들어 도 2의 (a)와 같이 변화됨에 따라가 그에 대응하는 전기신호가 고도계(1)에서 제어부(2)로 입력되었다면, 상기 제어부(2)에서는 소정 프로그램을 통해 도 2의 (b)와 같이 고도 변화율을 검출하여 고도의 증감과, 평행구간을 구분하고 그에 부응하는 모터 정,역방향 구동신호를 모터 구동부(3)로 출력하게 된다.At this time, when the altitude change of the driving vehicle changes as shown in, for example, (a) of FIG. 2, when an electric signal corresponding thereto is input from the altimeter 1 to the control unit 2, the control unit 2 selects a predetermined value. As shown in (b) of FIG. 2 through the program, the altitude change rate is detected, and the motor section 3 outputs the motor forward and reverse driving signals corresponding to the increase and decrease and the parallel section.

따라서, 상기 모터 구동부(3)에서는 이와같은 상기 제어부(2)의 출력신호에 입력받아 그에 부응하는 방향과 회전수를 갖도록 상,하각 조절용 모터(4)를 정방향 또는 역방향으로 구동시키게 된다.Accordingly, the motor driving unit 3 receives the output signal of the control unit 2 and drives the upper and lower angle adjusting motors 4 in the forward direction or the reverse direction so as to have a direction and a rotation speed corresponding thereto.

그러므로, 상하부로 회동 가능하게 축지되어 있는 헤드램프(5)와 기어나 링크 등으로 연결된 형태로 설치되어 있는 상기 상,하각도 조절용 모터(4)가 상기 모터 구동부(3)의 출력신호에 부응하여 정방향 또는 역방향으로 구동하게 되므로 헤드램프(5)의 빛 조사각이 상향 또는 하향으로 정해진 각도씩 고도 변화에 부응하여 자동 변화된다.Therefore, the upper and lower angle adjusting motors 4 installed in the form of the head lamp 5 rotatably pivoted up and down and connected by a gear or a link, etc. respond to the output signal of the motor driving unit 3. Since driving in the forward or reverse direction, the light irradiation angle of the headlamp 5 is automatically changed in response to the altitude change by the predetermined angle upward or downward.

즉, 오르막길에서는 그 각도에 부응하여 헤드램프(5)의 조사각이 하향으로 변화되고, 내리막길에서는 그에 반대로 상방향으로 자동 변화되므로 운전자의 전방 시야를 그 많큼 넓게 확보할 수 있는 것이다.That is, on the uphill road, the irradiation angle of the headlamp 5 changes downward in response to the angle, and on the downhill road, the forward angle of the headlamp 5 is automatically changed in the upward direction.

이와같이 고도계를 이용한 본 발명 장치는 이에 한정되는 것은 아니고, 스티어링센서 및 차속센서와 연동시켜 좌우각도까지 조절할 수 있는데, 이 경우에 있어서 좌우 스티어링 시스템을 이용한 좌우 헤드램프 조절보다는 방향계를 이용하여 좌우 헤드램프 조절 시스템으로 구성하는 것이 더 안정적으로 좌우 헤드램프 조절이 이루어질 것이다.Thus, the present invention using the altimeter is not limited to this, and can be adjusted to the left and right angles in conjunction with the steering sensor and the vehicle speed sensor, in this case, rather than the left and right headlamp control using the left and right steering system in the left and right head It would be more stable to configure the left and right headlamps with a lamp control system.

이상에서 설명한 바와 같이 본 발명에 의하면, 자동차내에 고도계를 설치하여 주행중 자동차의 고도 변화 데이타를 입력받아 제어부로 하여금 고도 변화율을 분선한 후 그에 따라 모터를 통해 헤드램프의 조사각도가 자동으로 상,하향 조절되도록 하므로써, 운전자가 오르막길 또는 내리막길을 운전함에 있어서도 넓은 시야를 확보할 수 있어 보다 편안한 시야 확보를 통해 안전 운전을 수행할 수 있는 것이다.As described above, according to the present invention, the altimeter is installed in the vehicle to receive the altitude change data of the vehicle while driving, and the control unit divides the rate of change of the altitude, and accordingly the irradiation angle of the headlamp is automatically moved up and down through the motor. By adjusting, the driver can secure a wider field of view even when driving uphill or downhill, so that the driver can perform safe driving through more comfortable vision.
