차량용 연료주입관의 설치구조{Oil-pipe mounting structure for a automobile}Oil-pipe mounting structure for a automobile

본 발명은 차량용 연료주입관의 설치구조에 관한 것으로서, 보다 상세하게는연료탱크로 연료를 공급하는 연료주입관이 연료탱크의 패널에 용접되는 차량용 연료주입관의 설치구조에 관한 것이다.The present invention relates to an installation structure of a vehicle fuel injection pipe, and more particularly, to an installation structure of a vehicle fuel injection pipe in which a fuel injection pipe for supplying fuel to a fuel tank is welded to a panel of a fuel tank.

일반적으로 차량의 연료공급계통은 도 1에 도시된 바와 같이 차체바디의 측면에 오목하게 형성되어 연료를 주유하는 연료주입기가 통과되는 주유하우징(미도시)과, 상기 연료주입기로부터 배출된 연료가 저장되는 연료탱크(2)와, 상기 주유하우징과 연료탱크(2) 사이에 위치되어 상기 연료주입기로부터 배출된 연료를 연료탱크(2)로 안내하는 연료주입관(1)을 포함하여 구성된다.In general, the fuel supply system of the vehicle is formed in a concave side of the body body as shown in Figure 1, the fuel injection housing (not shown) through which the fuel injector for supplying fuel and the fuel discharged from the fuel injector is stored And a fuel injection pipe 1 positioned between the fuel housing 2 and the fuel tank 2 to guide the fuel discharged from the fuel injector to the fuel tank 2.

여기서, 상기 연료주입관(1)의 하단부는 상기 연료탱크(2)에 형성된 연료주입구(2b)와 연통되도록 연료탱크(2)에 고정된다.Here, the lower end of the fuel injection pipe (1) is fixed to the fuel tank (2) to communicate with the fuel injection port (2b) formed in the fuel tank (2).

이하, 종래 기술에 따른 차량용 연료주입관의 설치구조를 다음에서 설명한다.Hereinafter, the installation structure of the vehicle fuel injection pipe according to the prior art will be described below.

종래의 연료주입관(1)에는 도 2에 도시된 바와 같이 연료탱크(2)에 형성된 연료주입구(2b)와의 사이에 보조부재(3)가 위치되어 상기 연료주입구(2b)에 끼워지는 연료주입관(1)의 하단부가 밀봉되도록 한다.In the fuel injection pipe 1 of the related art, as shown in FIG. 2, an auxiliary member 3 is positioned between the fuel injection port 2b formed in the fuel tank 2 to insert the fuel injection port 2b. The lower end of the tube 1 is sealed.

상기 보조부재(3)는 상기 연료주입관(1)의 하단부가 끼워지는 지지부(3a)와, 상기 지지부(3a)의 하단부가 외측으로 돌출되어 상기 연료탱크(2)의 패널에 용접되는 플랜지(3b)로 구성된다.The auxiliary member 3 includes a support part 3a into which the lower end of the fuel injection pipe 1 is fitted, and a flange welded to the panel of the fuel tank 2 by protruding outward from the lower end of the support part 3a. 3b).

상기 플랜지(3b)에는 상기 연료탱크(2)의 패널 끝단과 경납땜(12) 공정에 의해 접합될 수 있도록 상기 지지부(3a)와 연결되는 부위가 하측방향으로 돌출된 오목부(3c)가 형성된다.The flange 3b is formed with a concave portion 3c in which a portion connected to the support portion 3a protrudes downward to be joined to the panel end of the fuel tank 2 by a brazing process 12. do.

그리고, 상기 플랜지(3b)는 상기 연료탱크(2)의 패널과 점용접(11)되어 상기 경납땜(12) 공정에 의해 연료탱크(2)의 강도가 저하되는 것을 방지한다.The flange 3b is spot welded 11 with the panel of the fuel tank 2 to prevent the strength of the fuel tank 2 from being lowered by the brazing 12 process.

이때, 상기 플랜지(3b)의 끝단(3d)은 상기 점용접(11)시 상기 플랜지(3b)와 연료탱크(2)의 패널이 밀착되도록 하측방향으로 굽혀진다.At this time, the end 3d of the flange 3b is bent downward so that the flange 3b and the panel of the fuel tank 2 come into close contact with each other during the spot welding 11.

상기와 같이 구성된 종래 기술에 따른 차량용 연료주입관 설치 작업은 먼저, 보조부재(3)를 상기 연료탱크(2)의 연료주입구(2b)에 끼워 상기 연료탱크(2)의 패널 끝단이 상기 보조부재(3)의 오목부(3c)에 위치되도록 한 다음, 상기 보조부재(3)의 지지부(3a)에 연료주입관(1)의 하단부를 끼운다.The vehicle fuel injection pipe installation work according to the prior art configured as described above, first, by inserting the auxiliary member (3) into the fuel inlet (2b) of the fuel tank (2) the panel end of the fuel tank (2) is the auxiliary member (3) is positioned in the recess 3c, and then the lower end of the fuel injection pipe 1 is fitted to the support 3a of the auxiliary member 3.

그리고, 상기 연료주입관(1)을 지지부(3a)의 상단에 용접(10)하여 상기 연료주입관(1)의 하단부가 밀봉되도록 한다.Then, the fuel injection pipe 1 is welded 10 to the upper end of the support part 3a to seal the lower end of the fuel injection pipe 1.

다음, 상호 밀착된 상기 연료탱크(2) 패널과 플랜지 사이에 전류가 공급되면 상기 밀착 부위가 용융되면서 상기 연료탱크(2)의 패널과 플랜지(3b)가 접합된다.Next, when a current is supplied between the fuel tank 2 panel and the flange which are in close contact with each other, the panel and the flange 3b of the fuel tank 2 are joined while the close contact portion is melted.

그리고, 상기 연료탱크(2)의 패널 끝단과 보조부재(3)의 오목부(3c)는 산소불로 가열한 다음 경납을 투입하고, 경납이 용해되도록 다시 가열한다.In addition, the panel end of the fuel tank 2 and the recess 3c of the auxiliary member 3 are heated with oxygen fire and then charged with braze, and heated again to dissolve the braze.

이 때, 경납이 식으면서 상기 연료탱크(2)의 연료주입구(2b)가 밀봉되면 차량용 연료주입구 설치 작업이 완료된다.At this time, when the brazing is cooled and the fuel inlet 2b of the fuel tank 2 is sealed, the vehicle fuel inlet installation work is completed.

그러나 종래 기술에 따른 차량용 연료주입관의 설치구조는 연료주입관의 하단부가 보조부재의 지지부 상단에 용접되어 밀봉되고, 연료탱크의 연료주입구는 경납땜 공정에 의해 상기 보조부재의 오목부와 접합되어 밀봉되므로 상기 보조부재의 제조가 어려우며, 경납땜 공정이 복잡하여 설치 시간이 길어짐으로써 생산성이 저하된다.However, in the installation structure of the vehicle fuel injection pipe according to the prior art, the lower end of the fuel injection pipe is welded and sealed to the upper end of the support of the auxiliary member, and the fuel injection hole of the fuel tank is joined to the recess of the auxiliary member by a brazing process. Since the sealing is difficult to manufacture the auxiliary member, the brazing process is complicated, the installation time is long, the productivity is reduced.

또한, 경납은 납에 유해성 물질인 안티몬을 첨가한 합금이므로 납땜 공정중에 유해 가스 및 중금속 물질을 발생시켜 사람에게 피해를 줄뿐만 아니라 대기오염을 파괴하며, 경납땜 공정은 높은 온도에서 이루어지므로 상기 연료탱크의 표면처리가 손상되고, 연료탱크의 내구성 및 내식성이 저하되는 문제점이 있다.In addition, brazing is an alloy containing antimony, which is a harmful substance to lead, so that harmful gases and heavy metals are generated during the soldering process, which not only damages people but also destroys air pollution, and the brazing process is performed at a high temperature. There is a problem that the surface treatment of the tank is damaged, the durability and corrosion resistance of the fuel tank is lowered.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 설치 공정이 용이하고, 유해 가스 및 물질 발생을 방지하며 부품의 손상을 방지하는 차량용 연료주입관의 설치구조를 제공하는 데 있다.The present invention has been made to solve the above problems, an object of the present invention is to provide an installation structure of a fuel injection pipe for a vehicle that facilitates the installation process, prevents the generation of harmful gases and substances, and prevents damage to parts. have.
