Description
본 발명은 차량용 연료 경고등 점등장치에 관한 것으로, 보다 상세하게는 지연회로와 가변저항을 이용하지 않고 연료유동에 의한 불필요한 연료 경고등 점등을 방지해 부품수를 줄이면서 조립공정도 줄일 수 있도록 된 차량용 연료 경고등 점등장치에 관한 것이다.The present invention relates to a fuel warning light lighting device for a vehicle, and more particularly, a fuel for a vehicle that can reduce an assembly process while reducing the number of parts by preventing unnecessary fuel warning lights on due to fuel flow without using a delay circuit and a variable resistor. Warning light lighting device.
일반적으로 자동차에는 연료의 부족상태를 알려주는 연료경고장치가 마련되어 있어 운전자는 주행중에 이 연료경고신호를 보고 미리 연료를 채워 넣음으로써 주행중에 시동이 꺼지는 사고를 미연에 예방할 수 있게 되는 즉, 연료 경고등의 지시에 의해 사전에 충분한 연료를 보충토록 함으로써 차량의 안전운행을 도모하고 있다.In general, the vehicle is equipped with a fuel warning device that informs the state of fuel shortage, so that the driver can see the fuel warning signal while driving and fill the fuel in advance, thereby preventing the accident of starting off while driving. Safe driving of the vehicle is promoted by replenishing sufficient fuel in advance according to the instructions.
이와 같이 연료 부족을 경고하기 위한 방식중 도 1은 더미스터식 연료 경고등 점등장치를 도시한 것인데, 이러한 연료 경고등 점등장치는 일반 연료계의 회로와 병렬로 연결되어 있고 연료가 규정량 이하가 되면 더미스터(TH)가 작동하여 경고등(WL)을 켜서 운전자에게 경고하는 방식으로 되어 있다.1 shows a dummyster type fuel warning light illuminator, which is connected in parallel with a circuit of a general fuel system, and the fuel is lower than a specified amount. Mr. TH is operated to turn on the warning light WL to warn the driver.
그러나, 이와 같이 더미스터(TH)를 이용한 연료경고등장치는 연료탱크내에 설치된 더미스터(TH)가 연료속에 잠겨 있다가 연료의 소모로 인해 공기중에 노출되게 되면 더미스터(TH)의 방열이 이루어지지 않아 자체온도가 오르게되므로 더미스터(TH)가 도통되어 전류가 흐르게 됨으로써 바로 경고등에 불이 들어오도록 하는경고등 작동회로의 구성을 갖추고 있고 이로 인해, 주행중 차량의 진동으로 인해 연료액면에 진동(심한 유동)이 있을 경우 경고등(WL)에 불이 들어왔다 나갔다 하는 혼동스러운 상태가 발생하여 운전자를 혼란스럽게 함으로써 제때에 연료를 보충하지 못하여 뜻하지 않게 주행중에 시동이 꺼져 도로 한가운데서 곤욕을 치러야하는 사고를 당하는 경우를 왕왕 겪어 왔었다.However, as described above, the fuel warning device using the dummyster TH does not radiate the dummyster TH when the dummyster TH installed in the fuel tank is immersed in the fuel and exposed to the air due to the consumption of the fuel. As the self temperature rises, the dummyster (TH) is turned on so that the current flows, and thus the warning lamp operation circuit is set so that the warning lamp lights up.Therefore, the vehicle vibrates on the fuel liquid surface due to the vibration of the vehicle while driving. Warning lights (WL) on and off, confusing the driver, causing them to refrain from fueling in time, accidentally turning off the car while driving, and having a hard time in the middle of the road. I've been through the king.
이에 따라, 이와 같은 단점을 방지하고자 온도에 따라 저항값이 변하는 더미스터(TH)와 미터세트상에 설치되는 경고등(WL) 사이에 경고등작동지연회로(DDC)를 설치하여 연료의 유동으로 인한 경고등(WL)의 오점등현상을 완전 차단 할 수 있게 하는데, 이와 같은 경고등작동지연회로(DDC)는 도 2에 도시된 바와 같이 콘덴서(C1)의 충전작용 및 스위칭소자인 단접합 트랜지스터(PUT) 및 사이리스터(SCR)의 스위칭 작용으로 전류의 흐름지연이 이루어지도록 함으로써 연료의 부족으로 더미스터(TH)가 도통되더라도 일정시간(6∼8초) 경과 후에 연료경고등(WL)에 불이 들어오도록 된다.Accordingly, in order to prevent such a disadvantage, a warning lamp operation delay circuit (DDC) is installed between the dummyster (TH) whose resistance value changes with temperature and the warning lamp (WL) installed on the meter set to prevent such a disadvantage. It is possible to completely cut off the WL (lighting) phenomenon, such a warning lamp operation delay circuit (DDC) is a single junction transistor (PUT) and the charging and switching elements of the capacitor (C1) as shown in FIG. Since the current flow is delayed by the switching action of the thyristor SCR, the fuel warning lamp WL lights up after a predetermined time (6 to 8 seconds) even when the dummy star TH is turned on due to lack of fuel.
여기서, 미설명 도면부호 IG는 밧데리에 연결된 전원단자를 표시한다.Here, the non-explained reference numeral IG indicates a power terminal connected to the battery.
이와 같은 연료 경고등 장치는 연료의 계속적인 사용으로 인해 연료탱크에 충만되어 있던 연료의 수위가 떨어져 연료가 일정수위 이하가 되면, 연료탱크내에 설치되어 있는 더미스터(TH)가 연료에 잠겨 있다가 공기중을 노출되어 자체온도의 상승에 의해 저항값 저하와 함께 흐르는 전류가 다이오드(D1)와 저항(R1)을 통해 일단 콘덴서(C1)에 충전되고 이에 따라, 전류가 이 콘덴서(C1)에 충전되는 시간 동안에는 경고등(WL)에는 불이 들어오지 않게 된다.The fuel warning lamp device is such that when the fuel level filled in the fuel tank drops due to the continuous use of the fuel, and the fuel level is lower than the predetermined level, the dummyster TH installed in the fuel tank is immersed in the fuel. The current that is exposed to the middle and flows along with the decrease in the resistance value due to the increase of its own temperature is charged to the capacitor C1 through the diode D1 and the resistor R1 and thus the current is charged to the capacitor C1. During the time, the warning light WL will not light up.
그러나, 일정시간 경과 후 콘덴서(C1)의 충전이 완료되면 저항(R1)을 통해 흐르는 전류가 단접합 트랜지스터(PUT)를 통해 흐르게 되고, 이어서 사이리스터(SCR)가 도통되어 사이리스터(SCR)를 통해 전류가 흘러 경고등(WL)이 점등되므로 결국, 상기 경고등(WL)에는 더미스터(TH)가 온(ON)상태가 된 후 일정시간이 경과한 다음에 불이 들어오게 되는 것이다.However, when the charging of the capacitor C1 is completed after a certain period of time, the current flowing through the resistor R1 flows through the single junction transistor PUT, and then the thyristor SCR conducts and the current flows through the thyristor SCR. Since the warning light WL is turned on, the warning light WL turns on after a predetermined time elapses after the dummyster TH is turned on.
그러나, 이와 같은 경우에는 더미스터와 함께 별도의 지연 점등회로를 이용하여야 만 되므로 이는 제조비용과 제조 공정의 증가를 가져오는 단점이 있게 된다.However, in such a case, since a separate delay lighting circuit must be used together with the dummyster, this has the disadvantage of bringing about an increase in manufacturing cost and manufacturing process.
이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 더미스터나 사이리스터를 이용한 별도의 지연회로 없이 높은 점도의 실리콘오일과 마그네틱의 자력과 리드(Reed)스위치를 이용해 연료의 부족에 변화되는 연료 지시 포인터의 위치 변화를 통해 연료 경고등을 점등시켜 제조 공정과 제조 비용을 줄일 수 있도록 함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above-mentioned problems, and the fuel which is changed due to the shortage of fuel using the magnetic force and the reed switch of silicon oil and magnetic of high viscosity without a separate delay circuit using a dummyster or a thyristor The purpose is to reduce the manufacturing process and manufacturing cost by turning on the fuel warning light by changing the position of the pointer.
상기와 같은 목적을 달성하기 위한 본 발명은, 연료탱크내 연료량에 따라 다이얼패드상에 표시된 F(Full)과 E(Empty)사이를 이동하는 포인터와 함께 회전되는 회전링부위에 구비된 마그네틱과, 이 마그네틱의 근접에 따라 자기장을 형성하는 리드스위치로 이루어지되, 이 리드스위치는 포인터가 E(Empty)쪽으로 이동될 때 최대로 근접될 수 있는 위치로 배열됨과 더불어 연료탱크내 연료량에 따른 감지신호를 처리하는 연료게이지유니트와 전기적 회로를 형성하는 연료경고등 사이에 구비되어진 것을 특징으로 한다.The present invention for achieving the above object, and the magnetic provided in the rotary ring portion is rotated with a pointer to move between the F (Full) and E (Empty) displayed on the dial pad in accordance with the amount of fuel in the fuel tank, It consists of a reed switch which forms a magnetic field according to the proximity of the magnetic, which is arranged in a position where the pointer can be moved as close as possible when the pointer is moved toward E (Empty), and detects a detection signal according to the amount of fuel in the fuel tank. It is characterized in that it is provided between the fuel gauge unit to be processed and the fuel warning to form an electrical circuit.

도 3은 본 발명에 따른 차량용 연료 경고등 점등장치의 장착도를 도시한 것인바, 본 발명은 연료탱크내 연료량에 따라 다이얼패드(D)상에 표시된 F(Full)과 E(Empty)사이를 이동하는 포인터(P)와 함께 회전되는 회전링(PL)부위에 구비된 마그네틱(M)과, 이 마그네틱(M)의 근접에 따라 자기장을 형성하는 리드스위치(RSW)로 이루어지되, 이 리드스위치(RSW)는 도 4에 도시된 바와 같이 포인터(P)가 E(Empty)쪽으로 이동될 때 최대로 근접될 수 있는 위치로 배열되어지게 된다.Figure 3 shows the mounting of the fuel warning lamp lighting device for a vehicle according to the present invention, the present invention moves between F (Full) and E (Empty) displayed on the dial pad (D) according to the amount of fuel in the fuel tank The magnetic switch M is provided on the rotary ring PL portion which is rotated together with the pointer P, and the reed switch RSW forms a magnetic field in accordance with the proximity of the magnetic M. RSW is arranged in a position that can be as close as possible when the pointer P is moved toward E (Empty) as shown in FIG.
여기서, 상기 포인터(P)는 회전링(PL)의 끝단에 점도가 높은 실리콘오일을 충진해 연료센더로부터 측정된 저항값에 따라 다이얼패드(D)상에 표시된 F(Full)에서 E(Empty)쪽으로 이동될 때 상대적으로 느리게 회전되어지게 된다.Here, the pointer P is filled with silicon oil having high viscosity at the end of the rotary ring PL, and E (Empty) at F (Full) displayed on the dial pad D according to the resistance value measured from the fuel sender. It will rotate relatively slowly as it is moved to the side.
또한, 연료경고등(WL)은 도 5에 도시된 바와 같이 상기 마그네틱(M)에 의해 자기장을 형성하는 리드스위치(RSW)에 의해 연료탱크내 연료량에 따른 감지신호를 처리하도록 저항(R1,R2)과 코일(L1,L2)로 이루어진 연료게이지유니트(A)와 전기적 회로를 형성하게 된다.In addition, the fuel warning lamp WL has resistors R1 and R2 so as to process a detection signal according to the amount of fuel in the fuel tank by a reed switch RSW which forms a magnetic field by the magnetic M, as shown in FIG. 5. An electrical circuit is formed with the fuel gauge unit A including the coils L1 and L2.
이하 본 발명의 작동을 첨부된 도면을 참조로 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.
본 발명은 연료탱크에 충만되어 있던 연료의 수위를 감지해 연료 변화에 따른 전기 저항값인 연료량 감지신호가 연료게이지유니트(A)로 전송되면, 이 연료게이지유니트(A)를 거쳐 포인터(P)가 다이얼패드(D)상에 표시된 F(Full)과 E(Empty)사이를 이동하면서 연료탱크내의 연료량을 표시하게 되고, 이때 연료탱크의 수위가 일정수위 이하(즉, 연료 부족상태)가 되면, 상기 포인터(P)가 E(Empty)쪽으로 근접되면서 인접된 리드스위치(RSW)와 자기장을 형성하게 된다.The present invention detects the water level of the fuel filled in the fuel tank, and when the fuel amount detection signal, which is an electrical resistance value according to the fuel change, is transmitted to the fuel gauge unit A, the pointer P passes through the fuel gauge unit A. Moves between F (Full) and E (Empty) indicated on the dial pad D to display the amount of fuel in the fuel tank, and when the fuel tank level is below a certain level (i.e., low fuel level), As the pointer P approaches the E (Empty) side, the pointer P forms a magnetic field with the adjacent reed switch RSW.
이어, 상기 포인터(P)와 함께 회전되는 회전링(PL)에 구비된 마그네틱(M)이 리드스위치(RSW)쪽으로 근접됨에 따라 상기 마그네틱(M)과 리드스위치(RSW)사이에 자기장이 형성되고, 이와 같이 생성된 자기장에 의해 리드스위치(RSW)에 전류가 흐르게 된다.Subsequently, as the magnetic M provided in the rotary ring PL rotated together with the pointer P approaches the reed switch RSW, a magnetic field is formed between the magnetic M and the reed switch RSW. In this way, current flows through the reed switch RSW by the magnetic field generated as described above.
이에 따라, 상기 연료게이지유니트(A)를 거친 연료량에 대한 전류를 리드스위치(RSW)를 통해 연료경고등(WL)으로 흘려 점등시켜 운전자에게 경고하게 된다.Accordingly, the current for the fuel amount passed through the fuel gauge unit A flows into the fuel warning lamp WL through the reed switch RSW, thereby warning the driver.
이때, 연료센더로부터 측정된 저항값에 따라 다이얼패드(D)상에 표시된 F(Full)에서 E(Empty)쪽으로 이동되는 포인터(P)는 회전링(PL)의 끝단에 충진된 점도가 높은 실리콘 오일의 영향으로 점진적으로 반응하게 되는데 즉, 전술한 종래의 경우에 사용되는 더미스터나 사이리스터를 이용한 별도의 지연회로 없이 점도가 높은 실리콘오일을 이용해 포인터(P)의 E(Empty)까지의 이동시간을 지연한 다음 리드스위치(RSW)와 마그네틱(M)의 자기장을 이용해 연료경고등(WL)을 점등시키게 된다.At this time, the pointer P, which moves from F (Full) displayed on the dial pad D to E (Empty) according to the resistance value measured from the fuel sender, has a high viscosity silicon filled at the end of the rotary ring PL. It reacts gradually under the influence of oil, that is, the movement time to E (Empty) of the pointer P using a high viscosity silicone oil without a separate delay circuit using the dummy or thyristor used in the conventional case described above. Then, the fuel warning lamp WL is turned on by using the magnetic field of the reed switch RSW and the magnetic M.
즉, 연료센더로부터 측정된 저항값에 따라 F(Full)에서 E(Empty)쪽으로 이동되는 포인터(P)의 이동시간을 실리콘오일을 매개로 지연시킨 다음, 포인터(P)의E(Empty)근접에 따라 마그네틱(M)과 반응되는 리드스위치(RSW)를 통해 연료게이지유니트(A)와 연료경고등(WL)사이에 전기 회로를 형성시켜 연료부족에 따른 측정 저항값을 연료경고등(WL)으로 흘려 점등시키게 된다.That is, according to the resistance measured from the fuel sender, the moving time of the pointer P, which is moved from F (Full) to E (Empty), is delayed through the silicon oil, and then the E (Empty) proximity of the pointer P is performed. By forming an electrical circuit between the fuel gauge unit (A) and the fuel warning lamp (WL) through the reed switch (RSW) that reacts with the magnetic (M) to flow the measured resistance value of the fuel shortage to the fuel warning lamp (WL) It will light up.
이상 설명한 바와 같이 본 발명에 의하면, 연료탱크내 연료량을 표시하는 포인터와 함께 회전되는 회전링에 그 이동시간을 지연하도록 높은 점도의 실리콘오일을 충진하면서 연료게이지유니트와 연료경고등사이에 구비된 리드스위치에 자기장을 형성해 전류를 통전시키는 마그네틱이 구비되어, 더미스터의 공기중에 노출에 따른 연료경고등 작동시 발생되는 오작동과 사이리스터를 매개로 점등되는 연료경고등에 따른 별도의 지연 점등회로를 이용하지 않게 되므로 오작동에 따른 불편과 제조비용 및 제조 공정의 증가를 발생하지 않는 효과가 있게 된다.As described above, according to the present invention, a reed switch provided between a fuel gauge unit and a fuel warning lamp while filling a high viscosity silicon oil with a pointer for indicating the amount of fuel in the fuel tank to retard the moving time thereof. A magnetic field is formed in the magnetic field to energize the current, which prevents the use of a separate delayed lighting circuit due to the malfunction caused by the operation of the fuel warning lamp due to exposure to the air of the dummyster and the fuel warning lamp lit by the thyristor. There is an effect that does not cause inconvenience and increase in manufacturing cost and manufacturing process.
