본 발명은 자동차의 차속에 따라 능동적으로 전조등의 색상이 변화하도록 하므로서 야간 운전시 자기 차량의 속도변화를 인지할 수 있도록 하며, 또한 상대 차량의 주행속도 및 속도의 변화에 대한 인지 능력을 향상시켜서 안전운전에 도움을 줄 수 있도록 하는 차속 감지형 능동 등화장치에 관한 것이다. According to the present invention, the color of the headlamp is actively changed according to the speed of the vehicle, so that the speed change of the vehicle can be recognized at night driving, and the safety of the vehicle is improved by improving the perception ability of the change of the traveling speed and the speed of the other vehicle. The present invention relates to a vehicle speed sensing type active equalizer that can assist in driving.                         

기존 차량의 전조등은 로우(LOW) 및 하이(HIGH) 상태로 등화하도록 분류되어 있으며, 상기의 로우 등화상태는 빛이 차량의 전방 아랫쪽을 향해 조명하는 상태이며, 상기의 하이 등화상태는 전방을 향해 거의 직선상태로 조명하는 상태이다.The headlights of the existing vehicle are classified to be equalized in a low state and a high state. The low light state is a state in which light illuminates toward the front lower side of the vehicle. The lighting is almost straight.

상기와 같이 차량의 전조등을 로우 또는 하이 등화상태로 변화시켜주는 작동은 운전자가 운전 중 스티어링 휠 주위에 장착된 멀티 펑션 스위치(MULTI FUNCTION SWITCH)를 조작하여야만 등화상태를 변화시킬 수 있다.As described above, the operation of changing the headlight of the vehicle to the low or high equalization state can be changed only when the driver operates the MULTI FUNCTION SWITCH mounted around the steering wheel while driving.

그러나, 상기와 같은 전조등의 등화상태가 로우 또는 하이로 변화시키는 것은 운전자가 전방 시야를 확보하기 위한 수단일 수는 있겠으나, 차속의 변화를 인지시키는 수단이나 상대 차량에게 자기 차량의 주행속도를 인지시킬 수는 없었다.However, changing the lighting state of the headlamp to low or high may be a means for the driver to secure a forward view, but means for recognizing the change in the vehicle speed or the vehicle to recognize the driving speed of the vehicle. I could not make it.

때문에 야간에 차량을 운전하는 운전자는 같은 방향으로 운행 중인 상대 차량들의 전조등 불빛만으로는 차속을 인지하는 것이 불가능하기 때문에 안전운행에 불편을 겪게 된다. 예를 들어, 야간 운행시 차로변경을 위해 아웃 사이드 미러를 통해 후방에 차량이 다가오고 있다는 것을 감지하였다 하더라도 그 후방 차량의 주행속도를 인지할 수 없기 때문에 안전하게 차로를 변경하는데 어려움이 뒤따르게 되며, 특히 우천시에는 후방 시야의 확보가 더욱 곤란하여 주행 중 차로변경을 할 때 아웃 사이드 밀러를 통한 후방 차량에 대한 주행속도를 인지할 수 없기 때문에 차로변경하는데 접촉사고 또는 추돌사고의 위험이 뒤따르게 된다.Therefore, a driver driving a vehicle at night may experience inconvenience in safe driving because it is impossible to recognize the vehicle speed by only the headlights of the counterpart vehicles driving in the same direction. For example, even if the driver detects that the vehicle is approaching behind through the outside mirror to change lanes at night, it is difficult to change the lane safely because it cannot recognize the driving speed of the rear vehicle. In particular, when it is raining, it is more difficult to secure a rear view, so when changing lanes during driving, the driving speed of the rear vehicle through the outside miller cannot be recognized, resulting in contact or collision accidents.

본 발명은 상기와 같은 사항을 일소하기 위하여 제안된 것으로, 차량의 주행속도가 변화함에 따라 전조등의 불빛 색깔이 자동으로 변화하도록 하는 수단으로 야간 운행시 자기 차량의 속도변화는 물론이고 상대 차량의 속도변화까지 쉽게 인지할 수 있도록 하므로서 모든 차량의 안전운행에 기여할 수 있도록 할 뿐 아니라 아웃 사이드 미러를 통해 반사되는 후방 차량의 전조등 불빛의 색깔을 식별하여 후방 차량의 차속을 신속하게 인지할 수 있도록 하여 차로변경 등을 안전하게 수행할 수 있도록 하는데 목적을 두고 발명한 것이다.The present invention has been proposed to eliminate the above-mentioned matters, and means for automatically changing the color of the headlights as the running speed of the vehicle changes. It not only makes changes easy to recognize, but also contributes to the safe operation of all vehicles, and identifies the color of the headlights of the rear vehicle reflected through the outside mirror so that the speed of the rear vehicle can be recognized quickly. It is invented for the purpose of safely performing changes and the like.

본 발명은 상기와 같은 목적을 달성하기 위한 수단으로서,The present invention as a means for achieving the above object,

또한, 상기 컬러필터는 전조등의 불빛을 투명하게 여과시키는 제1 투명부와, 불빛을 여러가지의 유색으로 여과시키는 제2 내지 제4 컬러부로 이루어진 것임을 특징으로 한다.In addition, the color filter is characterized in that the first transparent portion for filtering the light of the headlight transparently, and the second to fourth color portion for filtering the light in various colors.

본 발명의 실시예를 첨부한 도면에 따라서 상세히 설명하기로 한다.Embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명을 설명하기 위하여 전체 구성을 나타낸 측면 단면도이며, 도 2의 (A)(B)(C)는 본 발명의 칼러필터의 작동상태 정면도를 도시한 것이다.1 is a side cross-sectional view showing the overall configuration for explaining the present invention, Figure 2 (A) (B) (C) is a front view showing the operating state of the color filter of the present invention.

도면부호 1은 전조등을 나타내는 것으로, 상기 전조등(1)은 프런트 헤드 램프(2)와 반사경(3) 및 투명판(4)으로 이루어져 있으며, 상기 프런트 헤드 램프(2)와 투명판(4) 사이에는 렌즈(5)가 설치되어 있는데, 상기한 렌즈(5)는 도 1의 도시와 같이 투명판(4)과 분리되어 있거나 또는 투명판(4)에 일체로 겹합된 구조로 형성될 수도 있다.Reference numeral 1 denotes a headlamp, wherein the headlamp 1 consists of a front headlamp 2, a reflector 3 and a transparent plate 4, between the front headlamp 2 and the transparent plate 4; The lens 5 is installed in the lens 5, which is separated from the transparent plate 4 as shown in FIG. 1 or may be formed in a structure integrally overlapped with the transparent plate 4.

본 발명의 특징은 상기 투명판(4)의 전방측에 전조등(1)의 불빛을 투명하게 여과시켜서 조명하는 것을 비롯하여 하나 이상의 유색상으로 여과시켜서 조명할 수 있는 컬러필터(6)를 마련하고, 또 상기 컬러필터(6)는 차량의 주행속도에 따라 왕복이동하면서 전조등(1)의 불빛을 변화시켜서 조명할 수 있도록 한 것에 있다.A feature of the present invention is to provide a color filter 6 that can be illuminated by filtering in one or more colors, including transparently filtering the lights of the headlamp 1 on the front side of the transparent plate 4, In addition, the color filter 6 is to change the light of the headlamp (1) and to illuminate while reciprocating according to the traveling speed of the vehicle.

이를 위해, 본 발명에서는 차속을 감지하는 모터제어유닛(7)으로부터 정,역 방향으로의 회전방향 및 회전수가 제어되는 모터(8)와, 이 모터(8)의 출력축에 설치된 구동기어(81)에 치합되어 왕복이동하는 래크기어(9)를 더 포함하여 구성되며, 상기 컬러필터(6)는 래크기어(9)에 일체로 결합된 채 래크기어의 길이방향으로 길게 형성되어 있으며, 또한 상기 컬러필터(6)는 프런트 헤드 램프(2)의 불빛을 투명하게 여과시켜서 조명하는 제1 투명부(6a)을 비롯하여 상기의 램프 불빛을 투명빛과는 구별되는 여러가지의 유색상으로 여과시켜서 조명하게 되는 제2 내지 제3 컬 러부(6b)(6c)(6d)가 순서대로 일렬 배치되어 있다.To this end, in the present invention, the motor 8 in which the rotation direction and the rotation speed in the forward and reverse directions are controlled from the motor control unit 7 for detecting the vehicle speed, and the drive gear 81 provided on the output shaft of the motor 8. It is configured to further include a rack gear (9) that is engaged in the reciprocating movement, the color filter (6) is formed long in the longitudinal direction of the rack gear while being integrally coupled to the rack gear (9), In addition, the color filter 6, including the first transparent portion 6a for illuminating the light of the front headlamp (2) by transparently filtered, and the lamp light is filtered in a variety of colors different from the transparent light The second to third color portions 6b, 6c and 6d to be illuminated are arranged in sequence.

상기에서의 모터제어유닛(7)은 차량이 주행하는 속도 즉, 차속이 입력되면 그 입력값을 미리 설정되어 있는 프로그램으로 연산하여 출력값의 범위내에서 상기 모터(8)를 정 방향 또는 역 방향으로의 회전 및 회전각을 결정하는 것이다.The motor control unit 7 in the above operation calculates the input value by a preset program when the speed at which the vehicle travels, that is, the vehicle speed is input, and moves the motor 8 in the forward or reverse direction within the range of the output value. To determine the rotation and angle of rotation.

한편, 상기 래크기어(9)는 이동안내구(도시 생략)에 의하여 수평상으로 왕복이동하도록 구성되어 있으므로 상기 컬러필터(6)는 래크기어(9)를 따라 안정된 상태로 왕복이동하게 되는 것이다.On the other hand, since the rack gear 9 is configured to reciprocate horizontally by a movement guide (not shown), the color filter 6 is reciprocated in a stable state along the rack gear 9 will be.

이와 같이 구성된 본 발명은 차량의 주행속도 즉, 차속의 변화를 감지하여 그 차속 입력값을 미리 설정되어 있는 프로그램으로 연산하여 출력값을 결정하고, 그 결정된 값을 정보화하여 모터(8)에 입력시키게 되면 상기 모터(8)는 구동기어(81)를 정 방향 또는 역 방향으로 설정각도로 회전시키게 되며, 이에 따라 구동기어(81)에 치합되어 있는 래크기어(9)가 좌측 또는 우측 방향으로 이동함에 따라 컬러필터(6)도 함께 이동하게 되는데, 이때 상기 컬러필터(6)에 형성된 제1 투명부(6a)가 투명판(4) 전방에 위치하고 있을 때에는 전조등(1)의 불빛은 투명하게 여과되어 조명되는 상태가 되며, 또는 제2 내지 제4 컬러부(6b)(6c)(6d)들 중 어느 하나가 투명판(4) 전방에 위치하게 되면 전조등(1)의 불빛은 그 해당 컬러부의 색상으로 여과되어 조명되는 것이다.The present invention configured as described above detects a change in the vehicle's traveling speed, that is, the vehicle speed, calculates the vehicle speed input value with a predetermined program, determines the output value, and inputs the determined value into the motor 8. The motor 8 rotates the drive gear 81 at a set angle in the forward or reverse direction. As a result, the rack gear 9 engaged with the drive gear 81 moves in the left or right direction. Accordingly, the color filter 6 is also moved together. When the first transparent part 6a formed on the color filter 6 is located in front of the transparent plate 4, the light of the headlamp 1 is transparently filtered. When the light is in the illuminated state, or when any one of the second to fourth color parts 6b, 6c, and 6d is positioned in front of the transparent plate 4, the light of the headlamp 1 is the color of the corresponding color part. Is filtered and illuminated.

상기와 같이 차속의 변화에 따라 상기 컬러필터(6)에 형성된 필터색상에 의해 전조등(1)의 불빛 색상이 변화하게 되면 운전자는 마주오는 차량의 주행속도를 인지할 수 있게 되고, 특히 아웃 사이드 미러를 통해 반상되는 후방 차량의 전조등 불빛의 색상을 식별하여 상대 차량의 주행속도를 신속하게 인지할 수 있게 되므로서 차로 변경 등을 안전하게 시도할 수 있게 되며, 또한 운전자는 자기 차량의 전조등에 의해 도로에 비춰지는 불빛의 색상을 보고 자기 차량의 주행속도를 인지할 수도 있게 된다.As described above, when the color of the light of the headlamp 1 is changed by the filter color formed in the color filter 6 according to the change of the vehicle speed, the driver can recognize the traveling speed of the oncoming vehicle, in particular, the outside mirror By identifying the color of the headlights of the rear vehicle, which is reflected through the vehicle, it is possible to quickly recognize the driving speed of the other vehicle, and thus, it is possible to safely attempt to change to a car, and also the driver You can also see the speed of your vehicle by looking at the color of the light.

상기와 같이 차량의 주행속도에 따라 전조등(1)의 불빛 색상을 변화시켜주는데 따른 본 발명의 일실시예는 하기 표와 같다.An embodiment of the present invention for changing the light color of the headlight 1 according to the traveling speed of the vehicle as described above is as follows.

위 표의 실시예와 같이 차속이 0∼80Km/h일 경우에는 모터(8)가 0∼360°의 범위내로 회전하게 되며, 이와 같은 모터(8)의 회전각도 범위내에서는 컬러필터(6)의 제1 투명부(6a)는 투명판(4) 전방에 위치하여 전조등(1)의 불빛을 투명하게 여과시켜서 조명하게 되는 것이며(도 2의 (A) 참조), 차속이 120Km/h 이상일 경우에는 모터(8)는 810∼900°의 범위내로 회전하게 되며, 이때에는 컬러필터(6)의 제4 컬러부(6d)가 투명판(4) 전방에 위치하여 전조등(1)의 불빛을 그 해당 색상으로 여과시켜서 조명하게 되는 것이다.(도 2의 (B) 참조)When the vehicle speed is 0 to 80 km / h as in the embodiment of the above table, the motor 8 rotates in the range of 0 to 360 °, and the color filter 6 of the color filter 6 is in the range of the rotation angle of the motor 8. The first transparent part 6a is located in front of the transparent plate 4 to transparently filter the lights of the headlamp 1 (see FIG. 2A), and when the vehicle speed is 120 Km / h or more The motor 8 is rotated within the range of 810 to 900 °. At this time, the fourth color part 6d of the color filter 6 is located in front of the transparent plate 4 so that the light of the headlamp 1 is applied. Filter by color to illuminate (see Figure 2 (B)).

그리고 차속이 120km/h 이상에서 점차로 감속될 때에는 모터(8)는 증속시의 회전방향과는 반대방향으로 회전하게 되므로서 컬러필터(6)는 감속된 차속의 범위내에 있는 컬러부가 투명판(4) 전방에 위치하게 된다. 예를 들어, 차속이 80∼100Km/h로 감속되었을 때에는 도 2의 (C) 도시와 같이 제2 컬러부(6b)가 투명판(4) 전방에 위치하게 되어 그 해당 컬러부의 색상으로 여과시켜 조명하게 되는 것이다.When the vehicle speed is gradually decelerated at 120 km / h or more, the motor 8 rotates in a direction opposite to the rotational direction at the time of increasing the speed, so that the color filter 6 has a color plate within the range of the decelerated vehicle speed. ) Will be located in front. For example, when the vehicle speed is reduced to 80 to 100 km / h, as shown in FIG. 2C, the second color part 6b is positioned in front of the transparent plate 4, and filtered by the color of the color part. Will be illuminated.

한편, 상기와 같이 차속의 변화에 따라 차량의 조명불빛이 로우(LOW), 미들(MIDDLE), 하이(HIHG) 상태로 변환되는 전조등에 적용하였을시에는 조명상황이 열악한 조건의 야간 운행시 후방 차량의 차속 변화를 더욱 신속하게 인지할 수 있게 되어 운전자들에서 안전한 운전하는데 많은 도움을 줄 수 있게 될 것이다.On the other hand, when applied to the headlight that is converted to the low, middle, high (HIHG) state of the vehicle lights according to the change in the vehicle speed as described above, the rear vehicle during night driving under poor lighting conditions Will be able to recognize changes in the vehicle's speed more quickly will help drivers to drive safely.

상기와 같은 본 발명은 차량의 차속에 따라 전조등 불빛을 여러 색상으로 변화시켜서 조명하게 되므로서 모든 차량을 운전하는 운전자는 야간 운전시 상대 차량의 전조등 불빛의 색상을 식별하여 그 차량의 차속을 신속하게 판단할 수 있게 되어 안전운행에 만전을 기 할 수 있게 하는 효과가 있으며, 특히 시야 확보가 어려운 우천시에도 상대 차량의 차속을 인지할 수 있게 되어 교차로에서의 교행이나 차로변경 등을 보다 안전하게 수행할 수 있게 하는 효과를 가져다주므로서 야간 운행시 불의의 사고를 미연에 방지할 수 있게 하는 등 안전운전에 커다란 장점을 제공하는 것이다.The present invention as described above is to change the headlights light in various colors according to the vehicle speed of the vehicle, so that the driver driving all vehicles to identify the color of the headlights of the other vehicle during the night driving to quickly determine the vehicle speed of the vehicle This makes it possible to make a perfect decision on safe driving, and to recognize the speed of the other vehicle even in rainy weather, especially when it is difficult to secure visibility. It provides a great advantage in safe driving, such as to prevent accidents in advance during the night operation by bringing the effect to make.
