본 발명은 차량용 와셔액 경고등 점등장치에 관한 것으로서, 더욱 상세하게는 차량의 엔진룸에 설치되는 와셔액탱크에 충입된 와셔액에 레이저를 조사하여 수위를 감지할 수 있는 차량용 와셔액 경고등 점등장치에 관한 것이다.The present invention relates to a vehicle washer liquid warning light lighting device, and more particularly to a vehicle washer liquid warning light lighting device that can detect the level of water by irradiating a laser to the washer liquid filled in the washer liquid tank installed in the engine room of the vehicle.

일반적으로 차량의 엔진룸 일측에는 전면유리에 분사되는 와셔액이 보관된 와셔액탱크가 설치되어 있다. In general, one side of the engine room of the vehicle is provided with a washer fluid tank in which the washer fluid sprayed on the windshield is stored.

상기의 와셔액탱크에는 와셔액이 보관되어 공급펌프에 의해 각 노즐로 공급되고, 공급된 와셔액은 차량의 전면유리에 분사되어 와이퍼의 브레이드가 전면유리를 원활하게 닦을 수 있도록 함으로써 운전자가 전방시야를 확보할 수 있는 것이다. The washer fluid is stored in the washer fluid tank and supplied to each nozzle by a supply pump. The washer fluid is sprayed onto the windshield of the vehicle to allow the wiper blade to wipe the windshield smoothly so that the driver can secure the front view. It can be.

특히, 이러한 와셔액은 비가 내린 후에 빗물과 노면의 먼지, 또는 흙이 범벅된 흙탕물이 전방차량의 주행으로 공중으로 튀어올라 차량의 전면유리에 맺히게 되면, 운전자는 전방시야의 확보가 어렵게 되고, 이로 인해 사고가 발생할 수 있는 것인데, 이때 운전자는 스티어링 휠의 하부에 설치된 윈드실드 와이퍼장치의 작동스위치와 와셔액 분사펌프 스위치를 작동시켜 와셔액의 분사와 동시에 브레이드를 작동시킴으로써, 전면유리에 맺힌 흙탕물을 닦아 전방시야를 확보할 수 있도록 하는 것이다. In particular, when the washer liquid rains and dirt on the road surface, or the muddy water of the soil jumped into the air by the driving of the vehicle ahead of the vehicle to form on the windshield of the vehicle, it is difficult for the driver to secure the front view. In this case, the driver operates the operation switch of the windshield wiper device installed under the steering wheel and the washer fluid injection pump switch to operate the braid at the same time as the washer liquid is sprayed, thereby cleaning the muddy water formed on the windshield. To ensure that.

상기와 같은 역할을 하는 와셔액은 비가 자주오는 계절에 소모되는 량이 많아지는데, 상기의 와셔액이 보관된 종래의 와셔액탱크는 엔진룸의 일측에 장착된 관계로 운전자가 용이하게 그 잔여량을 확인할 수 없었고, 주행중에 와셔액이 모두 소모되었을 때에는 윈드실드 와이퍼장치의 브레이드가 원할하게 작동하지 않아, 전면유리가 불투명해지게 됨으로써, 운전자가 전방시야를 확보하기 어려워 사고를 유발하는 문제점이 있었다. The washer fluid that acts as described above is consumed in a rainy season, but the conventional washer fluid tank in which the washer fluid is stored is mounted on one side of the engine room so that the driver cannot easily check the remaining amount. When the washer fluid was exhausted while driving, the braid of the windshield wiper device did not operate smoothly, so that the windshield became opaque, which made it difficult for the driver to secure the front view and caused an accident.

따라서 종래에는 와셔액 잔량을 감지할 수 있도록 도1에 나타낸 레벨 감지수단을 설치하고 있다.Therefore, conventionally, the level detecting means shown in Fig. 1 is provided to detect the remaining amount of the washer liquid.

상기 레벨 감지수단은 와셔액 탱크에 충입된 와셔액이 소모되면서 수면이 하강하면 플로트(1)가 하강된다, The level sensing means is a float (1) is lowered when the water level is lowered while the washer fluid filled in the washer fluid tank is consumed,

상기 플로트(1)가 일정위치로 하강되면 플로트(1)에 삽입된 자석(3)에 의해 리드 스위치(2)가 작동되는 것으로서, 상기 리드 스위치(2)는 유리 튜브(2a)의 내부에 한 쌍의 리드(2b)가 소정의 간격이 유지된 상태로 중첩되게 설치되어 있고, 상기 유리 튜브(2a)의 내부에는 불활성가스가 충입되어 있는 것이다.When the float 1 is lowered to a predetermined position, the reed switch 2 is operated by the magnet 3 inserted into the float 1, and the reed switch 2 is placed inside the glass tube 2a. The pair of leads 2b are provided so as to overlap in a state where a predetermined interval is maintained, and an inert gas is filled in the glass tube 2a.

따라서 상기 자석(3)에 의해서 리드(2b)의 접점이 접촉되어 전기가 흐르면서 운전석 계기판에 설치된 경고등을 점등시키고 있다.Therefore, the contact point of the lead 2b is contacted by the magnet 3, and electricity flows, lighting the warning lamp provided in the driver's seat instrument panel.

그러나 종래에는 플로트(1)가 와셔액 탱크에 충입된 수면에 부상된 상태로 상승 및 하강하게 되므로 차량 주행중 진동이 발생되면 플로트(1)가 원활하게 상승하지 못하게 되므로 와셔액의 보충시기를 정확하게 확인할 수 없게되는 문제점이 있었다.However, in the related art, the float 1 rises and descends while floating on the water filled in the washer fluid tank, so when the vibration occurs while the vehicle is running, the float 1 does not rise smoothly. There was a problem.

본 발명은 상기한 문제점을 해결하기 위하여 발명한 것으로서, 그 목적은 와셔액 탱크의 내측에 레이저를 조사하고, 수광부의 감지값에 따라서 와셔액의 보충시기를 간편하게 검출 및 표시할 수 있는 차량용 와셔액 경고등 점등장치를 제공함에 있다.The present invention has been made to solve the above problems, the object is to irradiate a laser to the inside of the washer liquid tank, the vehicle washer liquid warning light lighting device that can easily detect and display the replenishment time of the washer liquid in accordance with the detection value of the light receiving unit In providing.

A laser receiver installed at the bottom of the washer fluid tank for receiving, a controller for controlling the laser generator and the laser receiver, a warning light indicating that the washer fluid is being refilled to the driver by turning on the signal generated from the controller, and powering each part. Including the battery to supply.

이와 같은 특징을 갖는 본 발명을 상세하게 설명하면 다음과 같다.Referring to the present invention having such characteristics in detail as follows.

도2는 본 발명에 따른 와셔액 경고등 점등장치를 나타낸 개략도이고, 도3 및 도4는 본 발명에 따른 와셔액 경고등 점등장치의 작동 상태를 나타낸 개략도이다. Figure 2 is a schematic diagram showing a washer liquid warning light lighting device according to the present invention, Figure 3 and Figure 4 is a schematic diagram showing the operating state of the washer liquid warning light lighting device according to the present invention.

여기에서 참조되는 바와 같이 본 발명은 와셔액이 충입되도록 소정의 크기를 갖는 와셔액 탱크(10)가 마련되어 있고, 그 와셔액 탱크(10)의 상부에는 와셔액 탱크(10)의 내부로 레이저를 조사하기 위한 레이저 발생기(20)가 설치되어 있다.As referred to herein, a washer fluid tank 10 having a predetermined size is provided to fill a washer fluid, and a laser for irradiating a laser into the washer fluid tank 10 on the upper part of the washer fluid tank 10. The generator 20 is installed.

한편, 상기 와셔액 탱크(10)의 저면에는 상기 레이저 발생기(20)에서 발생되는 레이저를 수신하도록 레이저 수신기(21)가 설치되어 있되, 상기 레이저 발생기(20)와 레이저 수신기(21)는 와셔액 탱크(10)의 대각선 방향으로 서로 대향되게 설치하는 것이 바람직하다.On the other hand, the bottom of the washer fluid tank 10 is provided with a laser receiver 21 to receive the laser generated by the laser generator 20, the laser generator 20 and the laser receiver 21 is a washer fluid tank ( It is preferable to install them facing each other in the diagonal direction of 10).

그리고, 상기 레이저 발생기(20)와 레이저 수신기(21)는 콘트롤러(30)에 전기적으로 연결되어 있고, 상기 콘트롤러(30)에는 그 콘트롤러(30)에서 발생되는 신호를 입력받아 점등되어 운전자에게 와셔액 보충시기를 표시하는 경고등(40)이 연 결되어 있으며, 상기 각 부분에는 전원을 공급하는 배터리(50)가 전기적으로 연결되어 있다.In addition, the laser generator 20 and the laser receiver 21 are electrically connected to the controller 30, and the controller 30 is turned on by receiving a signal generated from the controller 30 to replenish the washer fluid to the driver. Warning lamp 40 to indicate the time is connected, the battery 50 for supplying power is electrically connected to each part.

이와 같이 구성된 본 발명을 상세히 설명하면 다음과 같다.Referring to the present invention configured as described in detail as follows.

먼저, 도3에 나타낸 바와 같이 와셔액 탱크(10)의 내부에 와셔액이 충입된 경우에는 레이저 발생기(20)에서 발생된 레이저가 와셔액에 의해서 굴절된 상태로 진행하게 되므로 와셔액 탱크(10)의 저면에 설치된 레이저 수신기(21)에는 레이저가 수신되지 않게 되는 것이다.First, as shown in FIG. 3, when the washer liquid is filled into the washer liquid tank 10, the laser generated by the laser generator 20 proceeds in a state refracted by the washer liquid. The laser is not received by the installed laser receiver 21.

따라서 콘트롤러(30)에서는 제어신호가 발생되지 않게되므로 경고등(40)은 소등된 상태를 유지하게 되는 것이다.Therefore, since the control signal is not generated in the controller 30, the warning lamp 40 is to be kept off.

한편, 와셔액이 소진되어 도4에 나타낸 바와 같이 와셔액의 수면이 레이저 수신기(21) 보다 하부로 낮아지면 레이저 발생기(20)에서 발생된 레이저는 굴절되지 않게 되므로 레이저 수신기(21)에서 수신하게 되는 것이며, 이때 콘트롤러(30)는 제어신호를 발생시키게 되는 것이며, 그 신호에 의해서 경고등(40)이 점등되어 운전자에게 와셔액 보충시기를 알려주는 것이다.On the other hand, when the washer fluid is exhausted and the water level of the washer fluid is lowered below the laser receiver 21 as shown in FIG. 4, the laser generated by the laser generator 20 is not refracted, and thus is received by the laser receiver 21. In this case, the controller 30 generates a control signal, and the warning lamp 40 is turned on by the signal to inform the driver of the washer fluid replenishment time.

이와 같이 본 발명은 와셔액 탱크에 설치된 레이저 수신기의 감지값에 따라서 와셔액의 수위를 검출하게 되므로 차량 주행시 발생되는 진동으로 인한 오작동을 미연에 방지할 수 있게 되는 특유의 효과가 있다.As described above, the present invention detects the water level of the washer fluid according to the detection value of the laser receiver installed in the washer fluid tank. Thus, the present invention has a unique effect of preventing malfunction due to vibration generated when driving the vehicle.
