일반적으로 자동차용 와이퍼 시스템은 와이퍼 모터를 구동시켜 그 회전력을 와이퍼 링크 어셈블리를 통해 와이퍼 블레이드에 전달하고, 이 와이퍼 블레이드가 글래스면에 소정의 압력으로 가압된 상태로 좌우 요동 운동을 하면서 글래스면을 닦아 주도록 구성되어 있다.In general, automotive wiper systems drive the wiper motor to transfer its rotational force to the wiper blades through the wiper link assembly, wiping the glass surface while rocking the glass surface while the wiper blade is pressed against the glass surface at a predetermined pressure. It is configured to give.
또한, 상기 와이퍼 시스템에는 글래스면이 지저분하거나 먼지가 말라 붙는 경우 이를 깨끗하게 닦아 내기 위해 와셔액 공급 장치가 구성되어 있다.In addition, the wiper system is provided with a washer liquid supply device to clean the surface of the glass if it is dirty or dust is dry.
상기 와셔액 공급 장치는 일정량의 와셔액이 충진되는 와셔액 탱크와, 이 와셔액을 와셔 노즐까지 공급해 주는 와셔 모터와, 후드에 장착되어 글래스면에 직접 와셔액을 분사시켜 주는 와셔 노즐로 구성되어 있다.The washer liquid supplying device includes a washer liquid tank filled with a predetermined amount of washer liquid, a washer motor for supplying the washer liquid to the washer nozzle, and a washer nozzle mounted on the hood to spray washer liquid directly onto the glass surface.
이와 같이 이루어진 와셔액 공급 장치는 와셔 모터 구동 스위치의 조작에 의해 와셔 모터가 구동함에 따라 와셔 노즐을 통해 와셔액을 정해진 분사 영역에 분사시켜 주게 된다.The washer liquid supplying device configured to spray the washer liquid into a predetermined injection region through the washer nozzle as the washer motor is driven by the operation of the washer motor driving switch.
그러나, 종래의 자동차용 와이퍼 시스템은 와셔 모터를 구동시킴에 따라 와셔 와셔 노즐을 통해 와셔액을 분사시켜 주게 되는데, 이때 와이퍼 블레이드가 와셔액 분사 영역에 있는 경우 글래스면에 충분한 와셔액이 공급되지 않아 다시 와셔액을 공급해 주어야 하기 때문에 와셔액의 소모량이 커지게 되어 이에 대한 개선이 필요하게 되었다.However, the conventional wiper system for automobiles injects the washer fluid through the washer washer nozzle as the washer motor is driven. In this case, when the wiper blade is in the washer fluid injection zone, the washer fluid is not supplied to the glass surface. Since it has to be supplied, the consumption of the washer liquid is increased, and an improvement is needed.
이를 개선하기 위해 운전자는 와셔액을 먼저 글래스면에 대해 분사한 다음 와이퍼 작동 스위치를 조작하게 되는데, 이때에는 주행중 이러한 2가지 동작을 행하여야 하기 때문에 안전 운행에 악영향을 주게 되었다.To improve this, the driver first sprays the washer fluid against the glass surface and then manipulates the wiper operation switch, which adversely affects safe driving since these two operations must be performed while driving.
본 발명은 이러한 점을 감안하여 안출한 것으로, 위치 감지 수단을 이용하여 와이퍼 블레이드 작동 위치를 검출하고, 이 와이퍼 블레이드가 글래스면의 와셔액 분사 영역 내에 있으면 와셔 모터의 구동이 잠시 OFF시켜 놓고 다시 이 분사 영역을 지나가게 되면 다시 와셔 모터가 ON되도록 함으로써, 와셔액이 와이퍼 블레이드에 분사되어 와셔액이 낭비되는 것을 막을 수 있으며, 특히 와셔액이 글래스면에 비정상적으로 분사되어 운전 시야를 가리는 것을 막아 안전 운행을 도모할 수 있는 자동차용 와이퍼 시스템을 제공하는데 그 목적이 있다.The present invention has been made in view of this point, and the position detecting means detects the wiper blade operating position, and if the wiper blade is in the washer liquid spraying region of the glass surface, the washer motor is temporarily turned off and the spraying is performed again. By passing the area, the washer motor is turned on again, thereby preventing washer fluid from being wasted on the wiper blades and wasting liquid.In particular, the washer fluid is abnormally sprayed on the glass surface to block the operation field. It is an object of the present invention to provide a wiper system for an automobile.

본 발명은 상기 와이퍼 블레이드(20)가 작동중에 글래스면의 분사 영역(A) 내에 있을 때에 분사 노즐(10)로부터 와셔액이 분사되는 것을 막아 주고, 이 와이퍼 블레이드(20)가 상기 분사영역(A)을 벗어나게 되면 다시 분사 노즐(10)을 통해 와셔액 분사가 이루어지도록 한 것이다.The present invention prevents the washer liquid from being injected from the spray nozzle 10 when the wiper blade 20 is in the spray region A of the glass surface during operation, and the wiper blade 20 prevents the spray region 20 from being sprayed. If it is out of the washer to the washer liquid injection through the injection nozzle 10 again.
이를 좀 더 상세하게 설명하면, 첨부도면 도 1에서 상기 와이퍼 블레이드(20)는 t1 →t2 →t3 →t4 →t5 →t6 →t1의 순서대로 순차적으로 작동을 하게 되는데, 본 발명에서는 상기 와이퍼 블레이드(20)가 와셔액이 분사되는 분사 영역(A)을 포함하는 구간인 t2와 t5 구간에서는 와셔 모터(30)가 OFF 상태로 두어 와셔액 분사가 이루어지지 않도록 제어기를 통해 제어하게 된다.In more detail, in the accompanying drawings, the wiper blade 20 operates sequentially in the order of t1 → t2 → t3 → t4 → t5 → t6 → t1. In the present invention, the wiper blade ( In the sections t2 and t5 which are sections 20 including the injection region A in which the washer fluid is injected, the washer motor 30 is turned off to control the washer fluid not to be injected.
상기 제어기(31)는, 첨부도면 도 2에서 도시한 바와 같이, 와셔 모터 작동 스위치(32)와 와이퍼 작동 스위치(21) 그리고 와이퍼 블레이드(20)의 회전 각도를 검출하기 위한 각도 검출 수단(22)으로부터 입력값을 받아 와셔 모터(30)의 구동 시기를 결정하게 된다.As shown in FIG. 2, the controller 31 includes angle detecting means 22 for detecting a rotation angle of the washer motor operation switch 32, the wiper operation switch 21, and the wiper blade 20. The driving time of the washer motor 30 is determined by receiving an input value from the washer.
여기서, 상기 각도 검출 수단(22)은 발광다이오드와 수광 다이오드를 통해 와이퍼 모터의 회전량에 따라 와이퍼 블레이드(20)의 위치를 검출할 수 있게 하는 것이 바람직하다.Here, the angle detecting means 22 preferably detects the position of the wiper blade 20 according to the amount of rotation of the wiper motor through the light emitting diode and the light receiving diode.
특히, 상기 제어기(31)는 와이퍼 작동 스위치(21)와 와셔 모터 작동 스위치(32)가 ON 상태에 있을 때에 와이퍼 블레이드(20)의 회전 각도를 판단하여 이 와이퍼 블레이드(20)가 분사 영역(A)을 벗어 났다고 판단될 때에, 상기 와셔 모터(30)를 구동시켜 주게 된다.In particular, the controller 31 determines the rotational angle of the wiper blade 20 when the wiper operation switch 21 and the washer motor operation switch 32 are in the ON state, so that the wiper blade 20 is in the injection zone A. When it is judged to be out of), the washer motor 30 is driven.
첨부도면 도 3은 이러한 제어기(31)의 제어를 각 구성 요소들의 시그날에 따라 도시한 것으로, 이를 참조하여 설명하면 다음과 같다.3 is a diagram illustrating control of the controller 31 according to signals of components, which will be described below with reference to the drawings.
먼저, 글래스면에 와셔액을 분사하기 위해 와셔 스위치를 작동시키게 되면 와셔 모터(30)와 미도시된 와이퍼 모터가 함께 구동을 하게 되는데, 상기 와셔 모터 작동 스위치(32)의 작동 시간(T)은 운전자에 의해 임의로 결정되게 되고, 이때 상기 와이퍼 모터는 이 작동시간(T)보다 미리 셋팅된 작동시간(t)만큼 더 전원 공급이 이루어지게 된다.First, when the washer switch is operated to inject the washer liquid onto the glass surface, the washer motor 30 and the wiper motor (not shown) are driven together, and the operating time T of the washer motor operation switch 32 is the driver. In this case, the wiper motor is supplied with more power by a preset operating time (t) than the operating time (T).
여기서, 상기 작동 시간(t)은 와이퍼 작동 스위치(21)가 와이퍼 블레이드(20)의 위치에 상관없이 OFF 시키더라도 이 와이퍼 블레이드(20)가 원래의 위치로 되돌아 올 수 있도록 하는 구동력을 제공하게 된다.Here, the operating time (t) provides a driving force that allows the wiper blade 20 to return to its original position even when the wiper operating switch 21 is turned off regardless of the position of the wiper blade 20. .
이때, 상기 와셔 모터(30)는 제어기(31)로부터 출력되는 시그날에 따라 ON과 OFF를 반복하게 되는데, 이러한 작용은 상기 각도 검출 수단(22)에 의해 이루어지게 된다.At this time, the washer motor 30 repeats the ON and OFF in accordance with the signal output from the controller 31, this action is made by the angle detection means (22).
즉, 상기 각도 검출 수단(22)은 와셔 모터(30)의 회전각도를 첨부도면 도 1에서 도시한 바와 같이 t1∼t6까지 구간을 정하여 지속적으로 전원을 ON 상태에 두게 되는데, 이때 상기 와이퍼 블레이드(20)가 분사 영역(A)에 들어가는 구간 즉, t2와 t5 구간에서는 상기 와셔 모터(30)에 공급되는 전원이 OFF가 되도록 출력 신호를 제어기(31)에 제공하게 된다.That is, the angle detecting means 22 determines the section from t1 to t6 as the rotation angle of the washer motor 30 as shown in the accompanying drawings, and keeps the power on continuously, wherein the wiper blade ( In the section 20 that enters the injection region A, that is, the sections t2 and t5, the output signal is provided to the controller 31 so that the power supplied to the washer motor 30 is turned off.
따라서, 상기 와셔 모터(30)는 와이퍼 블레이드(20)가 작동되면서 와셔액이 분사되는 분사 영역(A) 내에서는 작동하지 않게 되게 되는 것이다.Therefore, the washer motor 30 is not to operate in the injection region (A) in which the washer liquid is injected while the wiper blade 20 is operated.
이상에서 본 바와 같이 본 발명은 글래스면의 분사영역(A)에 와셔액을 분사해 주는 분사 노즐과, 이 노즐에 와셔액을 공급해 주는 와셔 모터를 포함하는 자동차용 와이퍼 시스템에 있어서, 상기 와셔 모터는 와이퍼 블레이드가 분사 영역(A) 내로 있는지 없는지를 판단하여 이 분사 영역(A)을 벗어난 위치에 있을 때에 와셔액을 제공하도록 제어기의 제어를 받는 것을 특징으로 하는 자동차용 와이퍼 시스템을 제공함으로써 다음과 같은 효과를 얻게 된다.As described above, the present invention provides an automobile wiper system including a spray nozzle for injecting washer liquid into a spraying area A of a glass surface, and a washer motor for supplying washer liquid to the nozzle, wherein the washer motor is a wiper.
