Description
본 발명은 자동차의 엔진오일량 표시장치에 관한 것으로, 특히 오일팬에 저장된 오일량을 운전석에서 알 수 있도록 함으로써 적시에 적량의 엔진오일을 공급할 수 있도록 된 자동차의 엔진오일량 표시장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for displaying an engine oil amount of an automobile, and more particularly, to an apparatus for displaying an engine oil amount of an automobile, in which a proper amount of engine oil can be supplied in a timely manner by allowing a driver's seat to know an amount of oil stored in an oil pan.
일반적으로 자동차 엔진의 실린더벽과 피스톤의 사이, 캠축과 캠축받침부의 사이 등의 섭동부위는 마찰에 의해 고열이 발생하게 되므로 적절한 윤활과 냉각을 시키지 않으면 변형 및 소착, 균열등이 발생하게 되어 엔진의 작동이 적상적으로 이루어질 수 없게 된다.Generally, perturbation parts such as the cylinder wall of the automobile engine and the piston, between the camshaft and the camshaft support part generate high heat due to friction. The operation cannot be done properly.
따라서, 엔진에는 실린더블록의 아래쪽에 오일팬을 장착하고, 이 오앨팬에 오일을 저장시킨뒤, 이 오일을 비산 및 펌핑작용에 의해 엔진내 각 섭동부와 실린더블록 내부로 공급함으로써 윤활 및 냉각을 실시하고 있다.Therefore, the engine is equipped with an oil pan under the cylinder block, and the oil is stored in the oil pan, and the oil is supplied to each perturbation part of the engine and inside the cylinder block by the scattering and pumping action to provide lubrication and cooling. We carry out.
그런데, 상기 엔진오일은 증발되어 엔진의 외부로 배출되게 되므로 시간이 지나면서 점차 그 양이 줄어들게 된다.However, since the engine oil is evaporated and discharged to the outside of the engine, its amount gradually decreases over time.
따라서, 종래에는 오일팬내에 고인 엔진오일이 일정수위 이하로 줄어들었을 때 운전석 앞쪽의 미터세트주위에 설치된 경고등을 점등시킴으로써 운전자가 엔진오일량의 부족을 인식하고 추가로 공급할 수 있도록 되어 있었다.Therefore, conventionally, when the engine oil accumulated in the oil pan is reduced below a certain level, a warning lamp installed around the meter set in front of the driver's seat is turned on so that the driver can recognize the lack of the engine oil and additionally supply it.
그러나, 상기와 같이 경고등에 의해 운전자가 엔진오일을 공급할 시기가 되었음을 인지하도록 된 경우에는 오일팬의 내부에 남아 있는 오일의 정확한 양을 알수 없으므로, 공급해야할 오일의 정확한 양을 알기가 어렵기 때문에 초보자는 물론 운전에 능숙한 사람도 적절한 양의 엔진오일을 공급하기 매우 어렵다는 문제점이 있었다.However, if the driver is aware that it is time to supply the engine oil as described above, the exact amount of oil remaining inside the oil pan cannot be known, so it is difficult to know the exact amount of oil to be supplied. Of course, even those skilled in driving had a problem that it was very difficult to supply an appropriate amount of engine oil.
이에 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 오일팬에 남아 있는 오일의 양을 정확한 수치로 표시해줌으로써 운전자가 운전석에 앉은채로 현재상태의 오일잔유량을 정확히 알 수 있게 하고, 또한 적시에 알맞은 양의 엔진오일을 공급할 수 있도록 된 자동차의 엔진오일량 표시장치를 제공함에 그 목적이 있다.Therefore, the present invention has been made to solve the above problems, by displaying the amount of oil remaining in the oil pan in an accurate value, so that the driver can know exactly the current oil remaining amount while sitting in the driver's seat, and also timely An object of the present invention is to provide an engine oil amount display device for a vehicle capable of supplying an appropriate amount of engine oil.

The sensing unit is composed of a plastic plate containing a plurality of metal wires arranged at regular intervals, a float containing a sensor for sensing the metal wires of the plastic plate, and the plastic plate is fixed and is mounted on the oil-side vertical wall. It is a fixed structure.
따라서, 상기 플로우트가 오일의 수위에 따라 상하이동하게 되며, 이때 플로우트의 센서가 상기 일정간격으로 배열된 금속선들을 감지하여 플로우트의 높이에 관한 신호가 디지탈변환기로 입력되며, 이에 의해 상기 표시부에 오일의 잔유량이 수치로 표시되게 된다.Accordingly, the float moves up and down depending on the oil level. At this time, the sensor of the float detects the metal wires arranged at the predetermined intervals, and a signal about the height of the float is input to the digital converter. The remaining amount will be displayed numerically.
이하 본 발명을 첨부된 예시도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 자동차의 엔진오일량 표시장치의 구성도로서, 본 발명은 오일팬(1)의 오일고임측수직벽(1a)에 설치되는 센싱부(2)와, 이 센싱부(2)의 신호를 받아 이 신호를 디지탈신호로 바꾸어주는 디지탈변환기(3)와, 이 디지탈변환기(3)에 의해 상기 오일팬(1)에 고인 오일의 양을 수치로 표시해주는 표시부(4)로 구성되어 있다.1 is a configuration diagram of an engine oil amount display device of a vehicle according to the present invention, the present invention is a sensing unit 2 which is installed on the oil high vertical wall 1a of the oil pan (1), and the sensing unit (2) A digital converter (3) for receiving a signal of the signal and converting the signal into a digital signal, and a display unit (4) for numerically displaying the amount of oil accumulated in the oil pan (1) by the digital converter (3). It is.
여기서, 디지탈변환기(3)와 표시부(4)는 운전석 앞쪽의 미터세트상의 임의의 위치에 설치되되 디지탈변환기(3)는 미터세트의 내측에 내장되고 표시부(4)는 외측으로 노출설치되며, 상기 센싱부(2)는 도 2에 도시된 바와 같이, 상기 디지탈변환기(3)에 연결된 센서(8)와, 이 센서(8)를 내장하는 플로우트(7)와, 이 플로우트(7)의 이동경로를 제공하면서 상기 센서(8)에 의해 감지되는 다수의 금속선(6a)를 내장한 플라스틱판(6)과, 이 플라스틱판(6)이 고정되는 고정브라켓(5)으로 이루어진다.Here, the digital converter 3 and the display unit 4 are installed at any position on the meter set in front of the driver's seat, but the digital converter 3 is embedded inside the meter set and the display unit 4 is exposed to the outside. As illustrated in FIG. 2, the sensing unit 2 includes a sensor 8 connected to the digital converter 3, a float 7 incorporating the sensor 8, and a movement path of the float 7. It consists of a plastic plate (6) containing a plurality of metal wire (6a) detected by the sensor (8) while providing a fixed bracket (5) to which the plastic plate (6) is fixed.
또한, 상기 센서(8)는 플로우트(7)에 내장되어지지만 그 표면은 플라스틱판(6)쪽으로 노출되어 있으며, 플라스틱판(6)에 내장되는 다수의 금속선(6a)들은 플라스틱판(6)내에서 상기 센서(8)쪽으로 치우쳐 설치되고, 도 3에 도시된 바와 같이 상하방향으로 상호 일정간격을 두고 배열되게 되며, 이 금속선(6a)들은 위쪽에서 아래쪽으로 또는 아래쪽에서 위쪽으로 갈수록 점차 지름이 일정량 줄어들거나 늘어나도록 배열되게 된다.In addition, the sensor 8 is embedded in the float 7 but its surface is exposed toward the plastic plate 6, and a plurality of metal wires 6a embedded in the plastic plate 6 are in the plastic plate 6. 3, the metal wires 6a are arranged to be spaced apart from each other in the vertical direction as shown in FIG. It is arranged to shrink or stretch.
여기서, 이 금속선(6a)들의 간격은 오일량이 0.1리터 변할 때 상승되거나 하강되는 플로우트(7)의 이동량과 같도록 다수의 반복실험을 거쳐 설정된다.Here, the spacing of these metal wires 6a is set through a number of repeated experiments so as to be equal to the movement amount of the float 7 which is raised or lowered when the oil amount is changed by 0.1 liter.
또한, 상기 플라스틱판(6)에는 도 4에 도시된 바와 같이 양측면에 오일고임측수직벽(1a)을 향하는 플랜지(6b)가 형성되어 플로우트(7)가 오일량의 변동에 따라 상하이동될 시 안정적인 이동이 가능하도록 되어 있으며, 이 플라스틱판(6)이 부착되는 상기 고정브라켓(5)은 ㄷ자 형상의 몸체 양단에 상기 오일고임측수직벽(1a)과 평행한 플랜지(5a)가 형성되어 이 플랜지(5a)가 오일고임측수직벽(1a)에 용접됨으로써 오일팬(1) 내에 고정되게 된다.In addition, as shown in FIG. 4, the plastic plate 6 is provided with flanges 6b facing both sides of the oil-standing vertical wall 1a, so that the float 7 is stable when the float 7 is moved in accordance with the variation in the oil amount. The fixing bracket 5 to which the plastic plate 6 is attached has a flange 5a parallel to the oil-side vertical wall 1a formed at both ends of the U-shaped body. 5a) is fixed to the oil pan 1 by welding to the oil-side vertical wall 1a.
따라서, 고여있는 오일이 줄어듦에 따라 상기 플로우트(7)는 하강하게 되고, 이에 의해 센서(8)의 위치도 변하게 되어, 이 센서(8)와 대응하게 되는 금속선(6a)도 달라지게 되므로 센서(8)는 대응되는 금속선(6a)에 따라 차별적인 전압을 발생시켜 상기 디지탈변환기(3)에 보내게 되며, 디지탈변환기(3)는 입력되는 전압값에 따라 미리 설정된 디지탈신호를 표시부(4)로 보내게 되며, 표시부(4)는 입력되는 디지탈신호에 따른 수치를 표시해주게 된다.Therefore, as the accumulated oil is reduced, the float 7 is lowered, thereby changing the position of the sensor 8, so that the metal wire 6a corresponding to the sensor 8 is also different. 8) generates a differential voltage according to the corresponding metal wire 6a, and sends the differential voltage to the digital converter 3, and the digital converter 3 transmits a preset digital signal to the display unit 4 according to the input voltage value. The display unit 4 displays the numerical value according to the input digital signal.
따라서, 운전자는 운전석에 앉은 상태에서 항상 수치로 표시되는 오일량을 확인할 수 있게 되므로, 오일의 잔유량을 정확히 알 수 있게 되고, 이에 따라 적시에 적정한 양의 오일을 공급해 줄 수 있게 된다.Therefore, the driver can check the amount of oil that is always displayed numerically while sitting in the driver's seat, so that the remaining amount of oil can be accurately known, and thus the right amount of oil can be supplied at the right time.
이상 설명한 바와 같이 본 발명에 따르면, 오일팬내 잔유오일량을 운전자가 용이하고도 정확하게 인지할 수 있게 됨으로써, 오일의 적시적량 공급이 매우 간편해지게 되는 효과가 있다.As described above, according to the present invention, since the driver can easily and accurately recognize the amount of remaining oil in the oil pan, there is an effect that the timely supply of the oil becomes very simple.
