Description
본 고안은 자동차 연료탱크용 부구(Car Fuel Sender Float)에 관한 것이다.The present invention relates to a vehicle fuel tank float (Car Fuel Sender Float).
자동차 연료탱크 내에는 연료 게이지 유니트 바디와, 이 바디에서 뻗어나가는 암, 그리고 암의 단부에 고정되어 연료탱크 내의 유면에 부상하는 부구로 이루어진 연료 게이지 유니트가 설치되어 유면의 변화에 따라 부구의 높이가 변화하고, 이 부구의 높이변화에 따라 선회하는 암의 가변량이 바디에서 차량 실내의 계기판에 있는 연료 게이지에 전달되어 운전자가 현재 연료탱크에 있는 연료의 량을 인식할 수 있도록 한 것이다.In the fuel tank of the vehicle, the fuel gauge unit body, the arm extending from the body, and the fuel gauge unit which is fixed to the end of the arm and floats on the oil level in the fuel tank are installed. A variable amount of pivoting arm, which changes as the height of the bulge changes, is transmitted from the body to the fuel gauge in the instrument cluster inside the vehicle, allowing the driver to recognize the amount of fuel currently in the fuel tank.
종래의 자동차 연료탱크 내에 설치되는 부구는 도 4 및 도 5와 같이 암(21)의 단부에 원통형의 발포 러버(22) 중앙을 끼워 고정시킨 것이다. 이 발포 러버(22)는 내유성 러버를 이용하여 직경이 30∼35㎜되고, 폭이 50∼60㎜되도록 200∼350% 발포시킨 것으로, 비중이 낮기 때문에 유면에 뜨게 된다.The fittings installed in the conventional vehicle fuel tank are fixed by fitting the center of the cylindrical foam rubber 22 to the end of the arm 21 as shown in Figs. The foamed rubber 22 was foamed with 200 to 350% of a diameter of 30 to 35 mm using a oil resistant rubber and 50 to 60 mm in width, and floated on the oil surface because of its low specific gravity.
그러나, 상기와 같은 종래의 부구는 발포 특성상 발포밀도를 균일하게 맞추지 못하여 공차가 크게 발생하므로 인하여 연료 게이지의 지침이 차량마다 서로 다르게 나타나는 문제가 있다. 이것은 부구의 중심이 유면과 일치되지 못하는 결과로 나타난다. 또 발포정도가 한계성을 가지고 있어 부구의 크기가 커지는 단점을 가지고 있었다.However, the above-described conventional mouth has a problem that the guideline of the fuel gauge is different from vehicle to vehicle because the tolerance is large because the foaming density is not uniformly adjusted due to the foaming characteristics. This results in the center of the sphere not coinciding with the surface. In addition, since the degree of foaming has a limit, the size of the ball had a disadvantage.
본 고안의 목적은 비중과 크기의 공차를 최소화시켜 부구의 중심과 유면을 일치시키므로서 게이지 지침불량문제를 해결하고자 하는데 있는 것이다.The purpose of the present invention is to solve the gauge guideline problem by minimizing the tolerance of specific gravity and size to match the center and the surface of the ball.

본 고안은 상기 목적을 달성하기 위하여, 부구 본체를, 암의 절곡된 단부가 조여질 수 있는 홈이 중심의 원주면에 형성되도록 내유성 플라스틱을 중공의 구체로 만든 것이다.In order to achieve the above object, the present invention is made of a hollow sphere made of oil-resistant plastic so that the grooves to which the bent end of the arm can be tightened are formed on the circumferential surface of the center.
본 고안은 상기와 같은 구성에 따라, 부구 본체를 블로우성형으로 만들게 되면 비중이 일정한 소형의 크기로 만들 수 있게 되고, 구체의 중심이 정확하게 유면에 뜨게 되어 게이지 지침이 차량마다 동일하게 나타난다.According to the above-described configuration, when the blow body is blow molded, the specific gravity can be made into a small size, and the center of the sphere is precisely floated on the surface so that the gauge instruction is the same for each vehicle.
이하 본 고안의 실시예를 첨부된 도면에 의하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
도 2 및 도 3은 암(1)의 단부에 부구 본체(2)가 끼워져 고정된 상태를 나타내고 있다. 부구 본체(2)는 암(1) 단부의 절곡부(3)가 조여질 수 있는 홈(4)이 중심의 원주면에 1/2의 원호를 넘는 우호의 구간에 반원형의 단면으로 형성된다. 이 부구 본체(2)는 내유성 플라스틱, 예컨데 폴리카보네이트수지 등을 사용하여 구형상으로 블로우형성한 것이다. 부구 본체(2)는 약간의 탄력을 가지고 있으므로 암(1)의 절곡부(3)에 밀어 끼우면 홈(4)이 도 2 및 도 3과 같이 결합된다.2 and 3 show a state in which the float main body 2 is fitted and fixed to the end of the arm 1. The float body 2 is formed in a semicircular cross section in a section of the friendship where the groove 4, through which the bent portion 3 at the end of the arm 1 can be tightened, exceeds a circular arc of 1/2 on the circumferential surface of the center. This float main body 2 is blow-molded in spherical shape using oil-resistant plastics, for example, polycarbonate resin. Since the float body 2 has some elasticity, the groove 4 is coupled to the bent portion 3 of the arm 1 as shown in FIGS. 2 and 3.
부구 본체(2) 내에는 대기보다 비중이 낮은 질소 또는 헬륨 등의 가스를 주입할 수 있다. 이에 따라 구체의 원재료인 플라스틱의 비중에 맞추어 유면과 부구 본체(2)의 중심과를 일치시킬 수 있게 된다.In the float main body 2, gas such as nitrogen or helium having a specific gravity lower than that of the atmosphere can be injected. As a result, the oil surface and the center of the float main body 2 can be matched with the specific gravity of the plastic which is the raw material of the sphere.
도 1은 연료탱크(5)의 상면 내부에 고정된 연료 게이지 바디(6)에서 암(1)이 뻗치고, 암(1)의 단부에 부구 본체(2)를 결합시킨 것으로, 부구 본체(2)가 유면(7)의 중심에 떠 있는 상태를 예시하고 있다.FIG. 1 shows that the arm 1 extends from the fuel gauge body 6 fixed inside the upper surface of the fuel tank 5, and the mouth body 2 is coupled to the end of the arm 1. The state floating in the center of the oil level 7 is illustrated.
이와 같은 본 고안은 비중과 크기의 공차를 최소화시켜 부구의 중심과 유면을 일치시키므로서 게이지 지침불량문제를 해결하게 되며, 내부에 비중이 낮은 가스를 충진시키면 비중의 조절과 함께 부구의 크기를 대폭 줄일 수 있고, 정밀성을 유지할 수 있으므로 여러 차종에 공히 적용할 수 있는 효과가 있다.The present design solves the problem of gage guide defect by minimizing the tolerance of specific gravity and size to match the center and oil level of the ball, and filling the gas with low specific gravity to greatly reduce the size of the ball with control of specific gravity. Since it can be reduced and maintains precision, there is an effect that can be applied to various vehicles.
