Description

자동차의 워셔액 분사각 조절장치Washer liquid injection angle adjusting device of car

본 발명은 자동차의 워셔액 분사각 조절장치에 관한 것으로, 좀더 상세하게는 차속에 따라 워셔액의 분사각도를 자동으로 조절하여 워셔액의 낭비를 줄일 수 있도록 하는 자동차의 워셔액 분사각 조절장치에 관한 것이다.The present invention relates to a washer fluid injection angle control device for a vehicle, and more particularly, to a washer fluid injection angle control apparatus for automatically reducing the washer fluid wasted by adjusting the injection angle of the washer liquid according to the vehicle speed.

종래의 자동차 워셔분사장치는 운전석이 워셔스위치의 조작에 따라 워셔펌프로부터 압송되는 워셔액을 노즐을 통해서 윈드실드로 분사되도록 하고 있다.Conventional automobile washer jet devices allow the driver's seat to spray washer fluid, which is pumped from the washer pump, by the operation of the washer switch to the windshield through the nozzle.

그러나, 종래의 워셔분사장치는 노즐이 후드에 고정장착되었기 때문에 워셔액의 분사방향이 항상 일정하게 되므로, 차량의 주행속도가 느릴 때는 워셔액이 윈드실드면에 적절하게 도포되지만, 차량의 주행속도가 빠를 때는 워셔액이 바람에 날려 윈드실드의 상단부 및 루프패널에 도포되어 낭비량이 크다는 단점이 있었다.However, since the conventional washer jet is fixedly mounted on the hood, the spraying direction of the washer fluid is always constant. When the running speed of the vehicle is slow, the washer liquid is properly applied to the windshield surface, but the running speed of the vehicle is fast. In this case, the washer fluid was blown by the wind, and was applied to the upper end of the windshield and the roof panel, which was a disadvantage in that the waste was large.

전술한 문제점을 해결하기 위해 안출된 본 발명은 워셔액을 분사시키면 차속에 따라 워셔액의 분사각도가 자동으로 조절되어 분사되도록 함으로써 윈드실드를 효과적으로 세정함과 아울러 워셔액의 낭비를 줄일 수 있도록 하는 자동차의 워셔액 분사각 조절장치를 제공하려는 목적이 있다.The present invention devised to solve the above problems is to wash the spray liquid by spraying the washer fluid is automatically adjusted according to the vehicle speed by spraying the washer liquid to effectively wash the windshield and to reduce the waste of the washer liquid The purpose is to provide an injection angle control device.

본 발명은 도시된 바와같이, 후드의 상부면에는 하우징(50)을 고착하고, 상기 하우징(50)에는 상하로 연장되는 장공(54)을 윈드실드(71)를 향해 개구시키고, 상기 하우징(50)에는 윈드실드(71)에 대해서 상하방향으로 회동가능하게 노즐바디(51)를 내재시키되, 상기 노즐바디(51)에는 상기 장공(54)을 통해 윈드실드(71)를 향해 워셔액을 분사하도록 분사구(52)를 형성하고, 상기 노즐바디(51)의 하단부에는 상기 노즐바디(51)의 회동에 무관하게 튜브(61)를 통해 압송되는 워셔액이 유입되도록 상기 분사구(52)로 관통되는 대구경의 유입구(53)를 형성하고, 상기 노즐바디(51)는 액츄에이터(M)의 구동축(Ma)의 회동에 따라 회동되어 상기 분사구(52)를 상기 장공(54)을 따라 회동시키도록 구성된다.As shown in the present invention, the housing 50 is fixed to the upper surface of the hood, and the housing 50 opens the long hole 54 extending upward and downward toward the windshield 71, and the housing 50 Inject the nozzle body 51 in the nozzle body 51 to be rotatable in the vertical direction with respect to the wind shield 71, the nozzle body 51 to spray the washer liquid toward the wind shield 71 through the long hole 54 A 52 is formed, and the lower end of the nozzle body 51 penetrates the injection hole 52 so that the washer fluid fed through the tube 61 flows into the lower end of the nozzle body 51 regardless of the rotation of the nozzle body 51. 53, the nozzle body 51 is rotated in accordance with the rotation of the drive shaft Ma of the actuator (M) is configured to rotate the injection port 52 along the long hole 54.

상기 액츄에이터(M)는 차속센서(VSS)의 신호로 차속이 일정속도를 초과하는지 여부를 감지하는 기준속도초과감지부(20)의 출력신호에 따라 정역구동되도록 구성된다.The actuator M is configured to be driven forward and backward according to the output signal of the reference speed over-sensing unit 20 that detects whether the vehicle speed exceeds a predetermined speed by the signal of the vehicle speed sensor VSS.

즉, 상기 기준속도초과감지부(20)에서 하이레벨의 신호가 출력되면 상기 기준속도초과감지부(20)의 출력단에 베이스접속된 트랜지스터(TR1) 및 상기 트랜지스터(TR1)의 턴언에 따라 스위칭되는 릴레이(K1)로 이루어진 정전류구동부(30)에서 상기 액츄에이터(M)의 정회전 구동단자로 전원전류(B+)를 인가하고, 상기 기준속도초과감지부(20)의 로우레벨의 신호가 출력되면 상기 기준속도초과감지부(20)의 출력단에 접속된 인버터(G1), 상기 인버터(G1)의 출력단에 베이스접속된 트랜지스터(TR2) 및 상기 트랜지스터(TR2)의 턴온에 따라 스위칭되는 릴레이(K2)로 이루어진 역전류구동부(40)에서 상기 액츄에이터(M)의 역회전 구동단자로 전원전류(B+)를 인가하도록 한다.That is, when a high level signal is output from the reference speed exceeding detection unit 20, the signal is switched according to the transistor TR1 connected to the output terminal of the reference speed exceeding detection unit 20 and the turn-on of the transistor TR1. The power supply current B + is applied to the forward rotation driving terminal of the actuator M from the constant current driver 30 formed of the relay K1, and when the low level signal of the reference speed excess detection unit 20 is outputted, Inverter G1 connected to an output terminal of the reference speed excess detection unit 20, a transistor TR2 connected to a base connected to the output terminal of the inverter G1, and a relay K2 switched according to the turn-on of the transistor TR2. The reverse current driving unit 40 is configured to apply the power supply current B + to the reverse rotation driving terminal of the actuator M.

상기 두 릴레이(K1,K2)로 공급하는 전원전류(B+)는 운전석 워셔스위치(도시생략)로부터 인가되도록 하면 더욱 바람직하다.More preferably, the power supply current B + supplied to the two relays K1 and K2 is applied from the driver's seat washer switch (not shown).

이와같이 구성된 본 발명은 윈드실드(71)로 워셔액을 분사시킬 때, 차속이 일정속도를 초과하게 되면, 차속센서(VSS)의 신호로 일정속도 초과여부를 판별한 기준속도초과감지부(20)는 하이레벨의 신호를 출력하게 되어 정전류구동부(30)의 트랜지스터를 턴온시킴에 따라 릴레이는 스위칭되어 전원전류(B+)를 인가하여 액츄에이터(M)를 정방향 구동시킨다. 이에 따라, 액츄에이터(M)의 구동축(Ma)은 도 3 에서 보아 시게방향으로 회동되어 분사구(52)를 윈드실드(71)의 하단부로 향하게 하므로, 워셔액은 윈드실드(71)의 하단부를 향해 분사된다.According to the present invention configured as described above, when the vehicle speed exceeds a predetermined speed when the washer fluid is injected into the windshield 71, the reference speed exceeding detection unit 20 that determines whether the predetermined speed is exceeded by the signal of the vehicle speed sensor VSS is As the high level signal is output and the transistor of the constant current driver 30 is turned on, the relay is switched to apply the power current B + to drive the actuator M in the forward direction. Accordingly, the drive shaft Ma of the actuator M is rotated in the direction of the see as shown in FIG. 3 so that the injection port 52 is directed to the lower end of the wind shield 71, the washer liquid is injected toward the lower end of the wind shield 71. do.

반대로, 차속이 일정속도 이하이면, 차속센서(VSS)의 신호로 일정속도 이하임을 판별한 기준속도초과감지부(20)는 로우레벨의 신호를 출력하게 되어 정전류구동부(30)의 트랜지스터를 턴온시킴에 따라 릴레이가 스위칭되어 전원전류(B+)를 액츄에이터(M)로 인가하므로 액츄에이터(M)는 역방향 구동하게 된다. 따라서, 액츄에이터(M)의 구동축(Ma)은 전술한 때와는 반대방향으로 회동되어 분사구(52)를 윈드실드(71)의 상단부로 향하게 하므로, 워셔액은 윈드실드(71)의 상단부를 향해 분사된다.On the contrary, if the vehicle speed is less than or equal to the constant speed, the reference speed over-sensing unit 20 that determines that the vehicle is less than or equal to the constant speed by the signal of the vehicle speed sensor VSS outputs a low level signal to turn on the transistor of the constant current driver 30. The relay is switched according to the power supply current (B +) to the actuator (M), the actuator (M) is driven in the reverse direction. Therefore, the drive shaft Ma of the actuator M is rotated in the opposite direction as described above to direct the injection port 52 toward the upper end of the windshield 71, so that the washer liquid is injected toward the upper end of the windshield 71. do.

이상에서 설명한 바와같이 본 발명은 워셔액을 분사시키면 차속에 따라 워셔액의 분사각도가 자동으로 조절되어 분사되도록 함으로써 윈드실드를 효과적으로 세정함과 아울러 워셔액의 낭비를 줄일 수 있도록 하는 효과가 있다.As described above, according to the present invention, when the washer fluid is sprayed, the spray angle of the washer fluid is automatically adjusted and sprayed according to the vehicle speed, thereby effectively cleaning the windshield and reducing waste of the washer fluid.
