자동차의 연료펌프 마운팅구조{A fuel pump mounting structure for a vehicle}A fuel pump mounting structure for a vehicle

본 발명은 자동차 엔진에 연료를 안정적으로 공급할 수 있도록 하는 연료펌프의 마운팅구조에 관한 것으로, 더 자세하게는 펌프헤드플레이트의 하단면과 연료탱크의The present invention relates to a mounting structure of a fuel pump that can stably supply fuel to an automobile engine, and more particularly, to the lower surface of the pump head plate and the fuel tank.

상단면 사이로 연료증발가스가 누출되지 않도록 한 것에 관한 것이다.To prevent fuel evaporation gas from leaking between the top surfaces.

일반적으로 자동차의 연료탱크에 저장된 연료로부터 증발되어 대기중으로 방출되는 연료증발가스는 대기를 오염시키게 되므로 법규로써 그 방출허용량을 규제하고 있는 바, 예를 들어 현재 북미에서 방출허용량은 2.0g/day이지만 이러한 정도의 방출허용량조차도 점차 줄이고 있는 실정이다.In general, fuel evaporation gas evaporated from the fuel stored in the fuel tank of an automobile and released into the atmosphere pollutes the air, and according to regulations, the emission allowance is regulated. For example, in North America, the emission allowance is 2.0 g / day. Even this discharge allowance is gradually decreasing.

한편 종래에 있어서 연료탱크에 취부되어 연료탱크 내의 연료를 엔진에 안정적으로 공급할 수 있도록 하는 연료탱크의 마운팅구조는 도 1 및 도 2와 같이 다수의 너트플레이트(22)가 용접된 연료탱크(21)에 링형의 러버씰(23)이 마련된 원판상의 펌프헤드플레이트(24)를 다수의 체결볼트(25)를 통해 조립하는 형태의 것이 주로 사용되었다.Meanwhile, in the related art, the mounting structure of the fuel tank, which is attached to the fuel tank to stably supply the fuel in the fuel tank to the engine, has a fuel tank 21 in which a plurality of nut plates 22 are welded as shown in FIGS. 1 and 2. In the form of assembling the disk-shaped pump head plate 24 provided with a ring-shaped rubber seal 23 through a plurality of fastening bolts 25, mainly used.

그러나 상기 종래의 연료탱크 마운팅구조는 다수의 체결볼트(25)를 통해 펌프헤드플레이트(24)를 연료탱크(21)에 조립하는 작업이 번거롭게 될 뿐 아니라 연료탱크(21)의 상단면과 러버씰(23)이 마련된 펌프헤드플레이트(24)의 하단면 사이로 많은 양의 연료증발가스가 누출되는 문제가 있었다.However, in the conventional fuel tank mounting structure, the work of assembling the pump head plate 24 to the fuel tank 21 through a plurality of fastening bolts 25 becomes cumbersome, as well as the top surface and the rubber seal of the fuel tank 21. There was a problem that a large amount of fuel evaporation gas leaked between the lower surfaces of the pump head plate 24 provided with (23).

상기 종래 구조에 있어서 체결볼트(25)를 통해 러버씰(23)이 가압되는 부위에서는 비교적 연료증발가스의 누출이 적게 되지만 체결볼트(25)가 설치되지 않는 부위에서는 러버씰(23)의 밀착력이 약하게 되므로 연료증발가스의 누출량이 비교적많게 된다.In the conventional structure, the leakage of fuel evaporation gas is relatively reduced in the portion where the rubber seal 23 is pressurized through the fastening bolt 25, but the adhesion force of the rubber seal 23 is reduced in the portion where the fastening bolt 25 is not installed. As they become weak, the leakage of fuel evaporation gas becomes relatively large.

본 발명은 상기 종래 자동차 연료펌프 마운팅구조의 제결함을 감안하여 안출한 것으로, 그 목적이 연료탱크와 펌프헤드플레이트 사이에서의 연료증발가스의 배출을 저감할 수 있도록 하는 자동차의 연료펌프 마운팅구조를 제공하는 데에 있는 것이다.The present invention has been made in view of the deficiencies of the conventional vehicle fuel pump mounting structure, the object is to provide a fuel pump mounting structure of the vehicle to reduce the emission of fuel evaporation gas between the fuel tank and the pump head plate It is to provide.

본 발명은 상기의 목적을 달성하기 위하여 연료탱크의 상단면에 링형 요입홈을 형성하는 동시에 다수의 고정돌기를 갖는 고정플레이트를 고정 설치하고, 연료탱크의 링형 요입홈에 밀폐링을 삽입 설치하며, 펌프헤드플레이트의 상단에 고정플레이트의 고정돌기와 대응되는 다수의 고정구멍을 갖는 록킹플레이트를 설치하는 것을 특징으로 하며, 이하 그 구체적인 기술내용을 첨부도면에 의거하여 더욱 자세히 설명하면 다음과 같다.The present invention is to form a ring-shaped recessed groove in the upper surface of the fuel tank in order to achieve the above object and at the same time fixedly install a fixed plate having a plurality of fixing projections, inserting the sealing ring in the ring-shaped recess of the fuel tank, Characterized in that the locking plate having a plurality of fixing holes corresponding to the fixing projections of the fixing plate on the upper end of the pump head plate, the following detailed description based on the accompanying drawings as follows.

즉, 도 3에는 본 발명의 한 실시예의 사시도가 도시되어 있고, 도 4에는 동 실시예의 요부 종단면도가 도시되어 있는 바, 본 발명은 연료탱크(11)의 상단면에 펌프헤드플레이트(14)가 설치되는 연료펌프 마운팅구조를 구성함에 있어서, 상기 펌프헤드플레이트(14)의 하단면과 대응되는 연료탱크(11)의 상단면에 링형 요입홈(11a)을 형성하는 동시에 요입홈(11a)의 바깥 둘레에 다수의 고정돌기(12a)가 내측에 방사상으로 마련된 링형의 고정플레이트(12)를 고정 설치하고, 연료탱크(11)의 요입홈(11a)에 밀폐링(13)을 삽입 설치하며, 펌프헤드플레이트(14)의 상단에 고정플레이트(12)의 각 고정돌기(12a)와 대응되는 다수의 고정구멍(15a)을 갖는 록킹플레이트(15)를 설치하여서 되는 것이다.That is, a perspective view of one embodiment of the present invention is shown in FIG. 3, and a longitudinal sectional view of the main part of the embodiment is shown in FIG. 4. In the present invention, the pump head plate 14 is disposed on the top surface of the fuel tank 11. FIG. In forming the fuel pump mounting structure is installed, the ring-shaped inlet groove (11a) is formed on the upper end surface of the fuel tank (11) corresponding to the lower surface of the pump head plate 14 at the same time of the inlet groove (11a) Fixing the ring-shaped fixing plate 12 provided with a plurality of fixing projections (12a) radially inside the outer periphery, inserting the sealing ring 13 into the recessed groove (11a) of the fuel tank 11, The locking plate 15 having a plurality of fixing holes 15a corresponding to each fixing protrusion 12a of the fixing plate 12 is provided at the upper end of the pump head plate 14.

상기와 같이 구성된 본 발명에 있어서는 요입홈(11a)에 밀폐링(13)이 삽입된 연료탱크(11)의 상단면에 펌프헤드플레이트(14)를 올려놓은 후 펌프헤드플레이트(14)의 상부로부터 록킹플레이트(15)의 각 고정구멍(15a)을 고정플레이트(12)의 각 고정돌기(12a)에 삽입하고 록킹플레이트(15)를 하부로 누르면서 일측으로 회전시키켜 록킹플레이트(15)와 고정플레이트(12)를 체결하면 도 4와 같이 밀폐링(13)이 균일하게 가압되면서 펌프헤드플레이트(14)의 하단면과 연료펌프(11)의 상단면이 면접촉하게 된다.In the present invention configured as described above, the pump head plate 14 is placed on the top surface of the fuel tank 11 in which the sealing ring 13 is inserted into the concave inlet groove 11a, and then from the top of the pump head plate 14. Insert each of the fixing holes 15a of the locking plate 15 into each of the fixing protrusions 12a of the fixing plate 12, and rotate the locking plate 15 downward while pressing the locking plate 15 downward. When the 12 is fastened, the sealing ring 13 is uniformly pressurized as shown in FIG. 4, and the bottom surface of the pump head plate 14 and the top surface of the fuel pump 11 are in surface contact.

따라서 본 발명에 있어서는 연료탱크(11) 내부의 연료증발가스가 면접촉 상태의 펌프헤드플레이트(14)와 연료펌프(11)에서 일차적으로 차단되고 펌프헤드플레이트(14)와 연료펌프(11)에 견고하게 밀착된 밀폐링(13)에 의해 2차적으로 차단되므로 외부로 누출되지 않게 된다.Therefore, in the present invention, the fuel evaporation gas inside the fuel tank 11 is first blocked by the pump head plate 14 and the fuel pump 11 in the surface contact state, and is connected to the pump head plate 14 and the fuel pump 11. Since it is secondarily blocked by the tightly closed sealing ring 13, it does not leak to the outside.

이상에서와 같이 본 발명은 연료탱크(11)와 펌프헤드플레이트(14)의 사이에 밀폐링(13)을 설치하고, 펌프헤드플레이트(14) 및 밀폐링(13)을 가압하는 록킹플레이트(15)를 연료탱크(11)에 고정 설치한 고정플레이트(12)에 결합한 것으로, 본 발명에 의하면 별도의 체결공구 없이도 보다 간편하고 신속하게 펌프헤드플레이트(14)를 연료탱크(11)에 조립할 수 있게 될 뿐 아니라 펌프헤드플레이트(14)와 연료탱크(11)를 면접촉시킬 수 있게 되고 밀폐링(13)을 균일한 가압력으로 펌프헤드플레이트(14)와 연료탱크(11)에 밀착시킬 수 있게 되어 연료탱크(11) 내부의 연료증발가스가 외부로 누출되는 것을 보다 확실하게 막을 수 있게 되므로 대기오염을 방지할 수 있게 됨은 물론 자동차의 상품성을 크게 향상시킬 수 있게 되는 등의 효과를 얻을 수 있게 된다.As described above, the present invention provides a locking ring (13) between the fuel tank (11) and the pump head plate (14) and pressurizes the pump head plate (14) and the sealing ring (13). ) Is coupled to a fixed plate 12 fixed to the fuel tank 11, and according to the present invention, the pump head plate 14 can be assembled to the fuel tank 11 more easily and quickly without a separate fastening tool. In addition, the pump head plate 14 and the fuel tank 11 can be brought into surface contact, and the sealing ring 13 can be brought into close contact with the pump head plate 14 and the fuel tank 11 with a uniform pressing force. Since the fuel evaporation gas inside the fuel tank 11 can be more reliably prevented from leaking to the outside, air pollution can be prevented and the merchandise of the vehicle can be greatly improved. .
