Description
본 고안은 자석을 이용한 연료량 표시장치에 관한 것으로서, 상세히는 프린트 기판에 저항값 인지용 도체를 인쇄하고, 이 도체 상에 부채꼴 형상으로 금속박판을 나란히 잇대어 접지단자를 구성하여, 상기 프린트 기판의 배면에서 자석을 부착한 가동부재가 플로트의 부력(浮力)에 따라 상기 저항값 인지용 도체 상을 좌우로 이동할 때, 상기 자석이 접지단자인 금속박판을 끌어당겨 프린트 기판의 도체와 접촉하여 접촉된 부위의 기설정된 저항값 감지 및 이에 따른 전류변화로 연료량 표시장치를 작동시키는 자석을 이용한 비접촉식 연료량 표시장치에 관한 것이다.The present invention relates to a fuel amount display device using a magnet, and in detail, a conductor for resistance value recognition is printed on a printed board, and a ground terminal is formed by connecting metal foils side by side in a fan shape on the conductor to form a ground terminal. When the movable member to which the magnet is attached moves left and right on the resistance detecting conductor according to the buoyancy of the float, the magnet is in contact with the conductor of the printed board by attracting the thin metal plate which is the ground terminal. The present invention relates to a non-contact fuel amount display device using a magnet that detects a predetermined resistance value and a current change accordingly.
일반적으로 자동차의 계기판에는 연료탱크 내에 저장되는 연료량이 어느 정도인지를 지시계로 나타내는 방식으로 연료량 지시계를 설치하고 있으며, 이 연료량 지시계는 연료탱크 내에 설치되는 연료량 표시장치에 의해 작동되는데, 이러한 연료량 표시장치의 일반적인 작동원리는 도 4에 도시한 바와 같이,In general, a fuel level indicator is installed on a dashboard of an automobile by an indicator indicating how much fuel is stored in the fuel tank, and the fuel level indicator is operated by a fuel level indicator installed in the fuel tank. As shown in FIG. 4, the general operating principle of
자동차의 연료탱크에 연료가 채워지면 플로트(10)가 연료량의 증가에 따라 상승되면서 지지대(11)가 동작되어 고정부재(12)에 고정된 가동부재(13)가 프린트 기판(14) 상에 인쇄되어 있는 저항값 인지용 도체(15)를 따라 좌측으로 이동하게 되고, 이때 상기 프린트 기판에 인쇄되어 있는 저항값 인지용 도체와 가동부재의 일측면에 설치한 접지단자(16)와의 접촉을 통해 저항변화를 이용한 전류변화로 연료량 지시계를 구동시키게 되며, 반대로 연료 탱크의 연료량이 감소함에 따라 플로트(10)가 낮아지게 되면서 가동부재(13)가 우측으로 이동하게 되어 상기와 동일한 동작에 의해 연료량 지시계를 구동시키게 된다.When the fuel tank of the vehicle is filled with fuel, the float 10 rises as the amount of fuel increases, and the support 11 is operated so that the movable member 13 fixed to the fixing member 12 is printed on the printed board 14. The resistance value recognition conductor 15 is moved to the left side, and at this time, the resistance value contact conductor printed on the printed board is contacted with the ground terminal 16 provided on one side of the movable member. The fuel level indicator is driven by the current change using the change. On the contrary, as the fuel amount of the fuel tank decreases, the float 10 is lowered and the movable member 13 moves to the right. Will be driven.
그런데, 상기한 바와 같이 접지단자와 저항값 인지용 도체와의 접촉을 통한 연료량 표시장치는 저항값 인지용 도체와 접지단자가 계속해서 접촉하고 있는 형태가 대부분이기 때문에, 어느 정도 사용기간이 경과한 후에 접촉부가 이물질 등에 의해 오염되는 경우가 자주 발생하게 되고, 이러한 문제로 인해 연료량 표시장치가 정상적으로 작동되지 않아 남아있는 연료량을 지시하는 지시계에 커다란 편차가 발생하게 된다.However, as described above, since the fuel amount display device through the contact between the ground terminal and the resistance value detecting conductor is mostly in the form of the resistance value conductor and the ground terminal continuously contacting each other, the use period of some time has elapsed. Often, the contact part is contaminated by foreign matters, etc., and this problem causes a large deviation in the indicator indicating the remaining fuel amount because the fuel level display device is not normally operated.
본 고안은 상기한 바와 같은 종래 접촉식 연료량 표시장치의 문제점을 개선하기 위해 안출된 것으로서, 종래에는 저항값 인지용 도체와 접지단자가 항상 접촉하고 있는 형태로 구성하였으나, 본 고안에서는 접지단자를 저항값 인지용 도체와 일정한 간격을 유지한 금속박판으로 구성하여, 자석의 자력에 의해 금속박판과 상기 도체가 접촉하는 형태로 구성한 비접촉식 연료량 표시장치를 제공함에 목적이 있다.The present invention was devised to improve the problems of the conventional touch fuel amount display device as described above, but in the prior art, the conductor for resistance value recognition and the ground terminal are always in contact with each other. It is an object of the present invention to provide a non-contact fuel amount display device composed of a thin metal plate having a constant distance from a value recognizing conductor, in which the thin metal plate is in contact with the conductor by a magnetic force of a magnet.

상기한 목적을 달성하기 위해서 본 고안은 프린트 기판 상에 저항값 인지용 도체를 인쇄하고, 이 도체와 소정의 간격을 두고 금속박판을 나란히 잇댄 형태로 접지단자를 구성하여, 상기 프린트 기판 상의 배면에서 상기 저항값 인지용 도체의 좌우로 이동하는 가동부재에 자석을 부착하여, 상기 도체와 금속박판으로 이루어진 접지단자가 자석에 의한 접촉을 통해 저항변화를 이용한 전류변화로 연료량 표시장치를 작동시킨다.In order to achieve the above object, the present invention prints a conductor for resistance value recognition on a printed board, and forms a ground terminal in the form of a metal plate parallel to the conductor at a predetermined distance from the conductor, A magnet is attached to a movable member moving left and right of the resistance recognizing conductor so that the ground terminal made of the conductor and the metal thin plate is operated by a current change using a resistance change through contact by a magnet.
이하, 첨부된 도면을 참조하여 본 고안의 자석을 이용한 비접촉식 연료량 표시장치의 구성을 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the non-contact fuel amount display device using a magnet of the present invention.
도 1은 금속박판으로 이루어진 접지단자를 보여주는 프린트 기판의 사시도, 도 2는 본 고안에 따른 연료량 표시장치의 배면 사시도를 도시한 것으로서, 본 고안은 도시한 바와 같이,1 is a perspective view of a printed circuit board showing a ground terminal made of a thin metal plate, Figure 2 is a rear perspective view of the fuel amount display device according to the present invention, as the present invention,
연료량 표시장치 본체(1)의 프린트 기판(2) 상에 인쇄된 저항값 인지용 도체(4)와, 이 도체와 소정의 간격을 두고 부채꼴 형상으로 금속박판(3)을 나란히 잇댄 접지단자(5)와, 상기 프린트 기판(2)의 배면에서 플로트(미도시)의 부력(浮力)에 따라 상기 플로트와 연결된 지지대(6)에 의해 상기 도체(4) 상을 좌우로 이동하는 가동부재(7)의 일측에 부착한 자석(8)으로 이루어진다.A resistance value conductor 4 printed on the printed circuit board 2 of the fuel amount display device 1, and a ground terminal 5 side by side connected with the metal thin plate 3 in a fan shape at a predetermined distance from the conductor. And a movable member 7 which moves left and right on the conductor 4 by a support 6 connected to the float in accordance with the buoyancy force of a float (not shown) on the rear surface of the printed board 2. It consists of a magnet 8 attached to one side of the.
따라서, 도 3에 도시한 바와 같이, 연료의 량에 따라 상승 및 하강하는 플로트에 의해 이와 지지대(6)로 연결된 가동부재(7)가 저항값 인지용 도체(4)의 배면을 따라 좌우로 이동하면, 상기 가동부재에 부착한 자석(8)이 동시에 이동하다가 자력에 의해 접지단자(5)로 작용하는 해당부위 2∼3개의 금속박판(3)을 끌어당기게 되고, 이로 인해 상기 금속박판과 도체가 접촉함으로써 접촉된 부위의 기설정된 저항값 감지 및 이에 따른 전류변화로 연료량 표시장치가 작동되어, 연료량 지시계로 연료탱크 내에 남아있는 연료의 잔량을 지시하게 된다.Therefore, as shown in FIG. 3, the movable member 7 connected to this and the support 6 by the float which rises and falls according to the quantity of fuel moves to the left and right along the back surface of the conductor 4 for resistance value recognition. When the magnet 8 attached to the movable member moves at the same time, two or three metal thin plates 3 serving as the ground terminals 5 are attracted by magnetic force, thereby attracting the metal thin plate and the conductor. The fuel level indicator is operated by detecting a predetermined resistance value of the contacted portion and the current change according to the contact, and the fuel level indicator indicates the remaining amount of fuel remaining in the fuel tank.
이상과 같은 목적과 구성으로 이루어진 본 고안에 따른 연료량 표시장치에 의하면, 자력이 작용하지 않는 부위는 도체와 접지단자인 금속박판이 항상 떨어져 있는 상태에서, 자력이 작용하는 해당부위 2∼3개의 접지단자(금속박판)만 도체와 접촉을 하게 되고, 이 접촉을 통해 저항변화를 이용한 전류변화로 연료량 표시장치를 작동시키기 때문에, 그만큼 상기 도체와 접지단자가 오염될 염려가 없어 연료량 표시장치가 언제나 정상적으로 작동되므로 제품에 신뢰성을 주는 효과가 있다.According to the fuel amount display device according to the present invention having the above object and configuration, the portion where the magnetic force does not act is grounded at the place where the magnetic force acts in the state where the conductor and the ground metal plate are always separated from each other. Since only the terminal (metal thin plate) comes into contact with the conductor, and the fuel level display device is operated by the current change using the resistance change through the contact, the fuel level display device is normally operated since there is no fear of contamination of the conductor and the ground terminal. It works, giving the product a reliability effect.
