본 발명은 차량 연료 검출장치에 관한 것으로, 특히 차량의 연료를 2개소에서 측정하여 주행시에도 정확한 검사가 이루어져 측정값의 신뢰도를 도모할 수 있도록 한 차량 연료 검출장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle fuel detection device, and more particularly, to a vehicle fuel detection device in which the fuel of a vehicle is measured at two places so that accurate inspection can be performed even during driving, thereby achieving reliability of the measured value.
차량의 연료 소모를 통지해 주는 검출장치의 일예로는 제1도와 같이 연료탱크(1)내의 연료(2) 표면에 뜨는 뜨개(3), 뜨개(3) 높이에 연동하여 온 오프되는 제2접점(P2), 제2접점(P2)이 온 될 때 제1접점(P1)이 온되는 바이메탈 릴레이(4), 바이메탈 릴레이(4)의 릴레이코일(5)에 전원을 공급하는 바테리(B+), 바테리(B+) 전원을 바이메탈 작동시 제1접점(P1)을 통해 공급받아 점등되는 연료표시등(FL)으로 이루어진다.As an example of the detection device that notifies the fuel consumption of the vehicle, as shown in FIG. 1, a second contact turned on and off in conjunction with the height of the knit 3 and the knit 3 floating on the surface of the fuel 2 in the fuel tank 1. (P2), the bimetal relay 4 which turns on the first contact point P1 when the second contact point P2 is turned on, the battery B + which supplies power to the relay coil 5 of the bimetal relay 4, The battery (B +) is made of a fuel indicator (FL) that is turned on when supplied via the first contact (P1) during the bimetal operation.
즉, 연료(2)가 어느 수준 이상이면 뜨개(3)가 높이 위치하여 제2접점(P2)이 오프되나, 연료(2)가 어느 수준 이하이면 뜨개(3)가 낮게 위치하므로 제2접점(P2)이 온되고, 이에 따라 바이메탈 릴레이(4)가 온되어 제1접점(P1)도 온 된다. 따라서 바테리(B+) 전원이 제1접점(P1)을 거쳐 연료표시등(FL)에 인가되는 것이며 이를 통해 사용자는 연료의 보충시기로 인식하게 된다.That is, if the fuel 2 is above a certain level, the knit 3 is positioned high and the second contact point P2 is turned off. If the fuel 2 is below a certain level, the knit 3 is located low, so the second contact point P P2) is turned on, whereby the bimetal relay 4 is turned on, and the first contact point P1 is also turned on. Therefore, the battery B + is applied to the fuel indicator FL through the first contact point P1, and the user is recognized as the fuel replenishment time.
그러나 경사진 면을 주행할때는 연료탱크(1) 내의 연료(2)가 기울어 지므로 연료가 없는데도 뜨개가 위로 올라가거나, 반대로 연료가 있는데도 없는 것으로 인식되는 경우가 있다.However, when traveling on the inclined surface, the fuel 2 in the fuel tank 1 is inclined, so that even though there is no fuel, the knit may rise up, or conversely, it may be recognized that there is no fuel.
즉, 제1도 상태에서 차가 앞으로 기울면 연료가 있음에도 불구하고 뜨개(3)가 내려앉아 접점(P2)이 온되고, 바이메탈 릴레이(4)도 온되어 접점(P2)이 온되므로 연료표시등(FL)이 점등되어 연료표시 경고등으로서의 역할을 제대로 할 수 없는 단점이 있다.That is, when the vehicle is inclined forward in the first degree state, despite the presence of fuel, the float 3 falls down and the contact point P2 is turned on, and the bimetal relay 4 is turned on so that the contact point P2 is turned on. ) Lights up so that it does not function properly as a fuel warning lamp.
본 발명은 이를 해결코자 하는 것으로 연료탱크 내부의 마주보는 모서리 2개소에 뜨개역할 벽을 설치하고 뜨개 역할벽에는 미세투과 홀을 형성시켜 경사진 곳을 주행시에도 2개소의 뜨개벽에서 저항값을 측정하는 방식으로 정확한 연료량 확인이 가능케 함을 특징으로 한다.The present invention is to solve this problem by installing a knitting role wall at two opposite corners inside the fuel tank and forming a micro-permeable hole in the knitting role wall to measure the resistance value at the two knitting walls even when driving inclined places. In this way, it is possible to check the exact amount of fuel.
즉, 본 발명은 연료탱크의 마주보는 높이 모서리 2개소에 뜨개벽을 형성하고 각 뜨개벽에는 다수의 미세투과홀을 형성하며, 각 뜨개벽의 저항값 변화는 제어부에서 인식하여 연료 잔량을 정확히 판단토록 이루어진다.That is, the present invention forms a float wall on two opposite height edges of the fuel tank, and a plurality of micro-perforated holes are formed on each float wall, and the change of the resistance value of each float wall is recognized by the controller to accurately determine the remaining fuel amount. It is done forever.
이하 본 발명의 실시예를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 발명의 사시도로서, 연료탱크(10)의 마주보는 높이 모서리 2개소에 뜨개벽(11)을 형성하고, 각 뜨개벽(11)에는 다수의 미세투과홀(12)을 형성한다. 그리고 양 뜨개벽(11)의 저항값 변화는 프로세서부(13)에서 인식하도록 구성하는 것이다.FIG. 2 is a perspective view of the present invention, in which a knit wall 11 is formed at two opposite height edges of the fuel tank 10, and a plurality of micro-permeable holes 12 are formed in each knit wall 11. In addition, the change in the resistance value of the double knit wall 11 is configured to be recognized by the processor unit 13.
제3도는 제2도를 사용한 등가회로 구성도로서, 각 뜨개벽(11)의 미세투과홀(12)을 통하여 연료탱크(10) 내의 연료높이와 일치하면서 양 뜨개벽(11)에 대응하는 각 가변저항(a,b)과, 각 가변저항(a,b)의 저항치를 디지털 값으로 각각 변환시킨후 메모리시킨 연료잔량 계산 알고리즘에 의해 연료 잔량값을 구동장치(15)로 출력하는 프로세서부(13)와, 구동장치(14)에 의한 구동값으로 디스플레이되는 디스플레이부(15)로 이루어진다.FIG. 3 is an equivalent circuit configuration diagram using FIG. 2, and corresponds to the height of the fuel in the fuel tank 10 through the micro-perforation hole 12 of each of the knit walls 11, respectively. A processor unit for converting the variable resistors (a, b) and the resistance values of the variable resistors (a, b) into digital values, respectively, and outputting the fuel residual value to the driving device 15 by a fuel residual calculation algorithm stored in memory ( 13) and the display unit 15 displayed by the drive value by the drive unit 14.
이와같이 구성한 본 발명을 사용할때에는 연료탱크(10)가 기울어져, 예를 들어 제3도의 가변저항(a)의 지정(a2)과 가변저항(b)의 지점(b1)이 쇼트되면 나머지 저항(a3-an)(b2-bn)의 저항값으로써 양측의 연료량 수평이 전면 또는 후면으로 어느정도 기울었는지를 판단케 하는 것이다. 물론 이러한 상태를 분석하여 결과 데이타를 구동장치(14)로 내보내고, 구동장치(14)의 구동에 따라 디스플레이부(15)에서 디스플레이 되는 것이다.When using the present invention configured as described above, the fuel tank 10 is inclined, for example, when the designation (a2) of the variable resistor (a) and the point (b1) of the variable resistor (b) of FIG. The resistance of -an) (b2-bn) determines how much the fuel level on both sides is tilted toward the front or rear. Of course, such a state is analyzed and the result data is exported to the driving device 14 and displayed on the display unit 15 according to the driving of the driving device 14.
본 발명의 핵심은 양측 뜨개벽(11) 구조와 각 뜨개벽(11)의 미세투과홀(12) 구조에 있는바, 주행로가 평탄치 못해 전회로 충렁일때에는 미세투과홀(12)에서 원료가 서서히 빠지므로 인해 생기는 지연시간으로 연료상태의 급격한 변동을 막을 수 있다.The core of the present invention is in the structure of the two side wall 11 and the micro-permeable hole 12 of each of the knit wall 11, the raw material in the micro-permeable hole 12 when the runway is not flat, and the entire circuit is blown. The lag slows down and prevents drastic fluctuations in fuel conditions.
또한, 경사길을 오르거나 내릴때에도 양측 뜨개벽(11)에 의한 가변저항(a, b)구조에 의해 연료의 평균량을 산출하므로 연료 잔량산출의 정확성을 기할 수 있다.In addition, since the average amount of fuel is calculated by the variable resistors a and b by the two side walls 11 even when the slope is going up or down, the fuel residual amount calculation accuracy can be determined.
이상과 같이 본 발명은 차량연료를 검출함에 있어서 연료탱크의 2개소 모서리에서 연료를 검출하고, 2개소 모서리에는 미세투과홀이 있는 뜨개벽을 형성하여 각각의 연료량에 대한 저항치로써 연료 잔량을 종합 분석하므로 오차없이 연료를 검출가능케 한다.As described above, the present invention detects fuel at two corners of a fuel tank in forming a vehicle fuel, and forms a floating wall having fine perforation holes at two corners to comprehensively analyze fuel residual amount as resistance to each fuel amount. Therefore, fuel can be detected without error.
