Description

차량 충돌시 연료 누출방지를 위한 리저버 컵의 단면구조Cross-section of reservoir cup to prevent fuel leakage in vehicle crash

본 고안은 차량 충돌시 연료 탱크의 연료 누출 방지를 위한 리저버 컵의 단면구조에 관한 것으로, 더 상세하게는 차량 충돌시 리저버 컵으로 인하여 연료 탱크가 자유롭게 변형되지 못하고, 연료 탱크내의 리저버 컵 용접부 주위의 파손으로 인해 연료가 누출되므로, 연료 탱크내의 리저버 컵 용접부 주위에 전둘레 노치를 형성하여 차량충돌시 상기 노치에 의해 쉽게 변형될 수 있게 하므로 연료 탱크내의 연료 누출을 방지 하기 위한 것이다.The present invention relates to a cross-sectional structure of a reservoir cup for preventing fuel leakage of a fuel tank during a vehicle crash. More specifically, the fuel tank is not freely deformed due to the reservoir cup during a vehicle crash. Since the fuel leaks due to breakage, the notch is formed around the reservoir cup weld part in the fuel tank so that it can be easily deformed by the notch when the vehicle crashes, thereby preventing fuel leakage in the fuel tank.

일반적으로 차량 충돌시 연료 탱크의 연료누출은 대형 사고를 발생시키므로 연료 탱크는 강판으로 만들고, 내부에는 연료의 출렁임을 방지함과 동시에 강성과 강도를 높이기 위한 리저버 컵이 설치되어 있으며, 주석 또는 아연 도금을 하여 방청 처리로 연료의 누출을 방지하고 있다.In general, fuel leakage of fuel tanks causes large accidents in vehicle collisions, so the fuel tanks are made of steel plate, and a reservoir cup is installed inside to prevent swelling of fuel and increase rigidity and strength. Anti-rust treatment prevents fuel leakage.

종래 자동차 연료 탱크내의 리저버 컵의 단면구조는 도 1 과 도 2 에서 도시된 바와 같이, 하단부가 돌출구성된 용접부(1')를 구비한 박스형의 리저버 컵(1)이 연료 탱크(2) 바닥부분에 용접 고정된다.The cross-sectional structure of a reservoir cup in a conventional vehicle fuel tank is shown in FIG. 1 and FIG. Welding is fixed.

도면중 미설명부호 3 은 연료펌프 필터를 나타낸 것으로, 연료에 포함되어 있는 수분과 먼지 등을 제거하는 것으로 일반적으로 비분해식이 사용되고, 내부에는 여과면적을 가능한 한 크게 할 수 있도록 만든 엘리먼트가 들어있다.In the drawing, reference numeral 3 denotes a fuel pump filter, which generally removes moisture and dust contained in the fuel, and is generally used in a non-degradable manner, and includes an element made to make the filtration area as large as possible. .

또한, 도면중 미설명부호 4 는 연료펌프를 나타낸 것으로, 연료 탱크에서 연료를 빨아 올려 연료분사장치 또는 기화기로 압송하는 장치로 DC 모터로 축전지 전원을 공급받아 구동되어 연료 탱크에 저장되어 있는 연료를 인젝터에 공급한다. 종류로는 엔진룸에 설치는 되어 있는 외장형과, 연료 탱크내에 설치되어 있는 내장형이 있으나 연료 펌프의 소음을 억제하고 베이퍼 로크 및 연료의 맥동을 방지하는 내장형이 많이 사용된다.In addition, reference numeral 4 in the drawing indicates a fuel pump, a device that sucks fuel from a fuel tank and pumps the fuel to a fuel injection device or a carburetor. Supply to the injector. Types include an external type installed in the engine room and a built-in type installed in the fuel tank, but a built-in type for suppressing noise of the fuel pump and preventing pulsation of vapor lock and fuel is frequently used.

이와 같이 구성된 연료 탱크(2)내의 리저버 컵(1)의 단면구조는 차량의 후방 충돌시 상기 리저버 컵(1)으로 인하여 연료 탱크(2)가 자유롭게 변형되지 못하고, 연료 탱크내(2)의 리저버 컵(1)의 용접부(1')의 손상으로 연료가 누출되어 화재의 위험으로 인한 대형 사고가 발생되는 문제점이 있었다.The cross-sectional structure of the reservoir cup 1 in the fuel tank 2 configured as described above is such that the reservoir cup 1 is not freely deformed due to the reservoir cup 1 in the rear collision of the vehicle, and the reservoir in the fuel tank 2 Fuel leaked due to damage of the welded portion 1 'of the cup 1 has a problem that a large accident occurs due to the risk of fire.

본 고안의 목적은 차량 충돌시 연료 탱크의 자유로운 변형으로 파손에 의한 연료 누출을 방지하여 연료 누출에 의해 발생되는 화재의 위험을 예방하여 차량의 신뢰성을 향상시키는 차량 충돌시 연료 누출방지를 위한 리저버 컵의 단면구조를 제공하는데 있다.The object of the present invention is to prevent fuel leakage due to breakage by free deformation of the fuel tank during vehicle collision, thereby preventing the risk of fire caused by fuel leakage and improving the reliability of the vehicle. To provide a cross-sectional structure.

상기 목적을 달성하기 위해 본 고안은 연료 탱크내의 리저버 컵의 용접부 주위에 노치를 형성하여 차량 충돌시 노치에 의해 연료 탱크가 쉽게 변형되도록 하여 연료 탱크에서 연료누출을 방지하여 차량의 신뢰성을 향상 시킬수 있도록 한 것이다.In order to achieve the above object, the present invention forms a notch around the welded portion of the reservoir cup in the fuel tank so that the fuel tank is easily deformed by the notch in the event of a vehicle crash, thereby preventing fuel leakage from the fuel tank and improving the reliability of the vehicle. It is.

본 고안은 도 3 에 도시된 바와 같이, 하단부가 돌출구성된 용접부(11) 주위의 전둘레에 노치(12)를 형성한 박스형의 리저버 컵(10)이 연료 탱크(20) 바닥부분에 용접 고정되는 것을 특징으로 한다.According to the present invention, as shown in FIG. 3, a box-shaped reservoir cup 10 having a notch 12 around the weld 11 having a protruding lower end portion is welded to the bottom of the fuel tank 20. It is characterized by.

이와 같이 구성된 본 고안은 차량 충돌시 연료 탱크(20)의 리저버 컵(10) 용접부(11)주위의 노치(12)에 의해 연료 탱크(20)가 자유롭게 변형이 되므로, 연료 탱크(20)의 연료의 누출을 방지하여 충돌안정성 및 차량의 신뢰성 향상으로 상품성을 향상시킬 수 있는 장점이 있다.According to the present invention configured as described above, since the fuel tank 20 is freely deformed by the notch 12 around the reservoir cup 10 welded portion 11 of the fuel tank 20, the fuel of the fuel tank 20 may be changed. It is possible to improve the merchandise by preventing collisions and improving the stability of the collision and the reliability of the vehicle.

이상에서 설명한 바와 같이 본 고안은 차량 충돌시 리저버 컵으로 인하여 연료 탱크가 자유롭게 변형되지 못하여 연료 탱크내의 리저버 컵 용접부위의 파손으로 인해 연료가 누출되므로, 연료 탱크내의 리저버 컵 용접부 주위에 전둘레 노치를 형성하여 차량충돌시 상기 노치에 의해 쉽게 변형되므로 연료 탱크내의 연료 누출을 방지 하여 차량의 신뢰성 향상으로 상품성을 향상 시킬 수 있는 효과가 있다.As described above, the present invention does not freely deform the fuel tank due to the reservoir cup during a vehicle collision, so that fuel leaks due to breakage of the reservoir cup welding portion in the fuel tank, so that the notch around the reservoir cup weld portion in the fuel tank is notched. Since it is easily deformed by the notch when the vehicle crashes, there is an effect that can prevent the leakage of fuel in the fuel tank and improve the merchandise by improving the reliability of the vehicle.
