본 발명은 연료펌프의 작동소음 감소를 위한 연료펌프 장착구조에 관한 것으로서, 특히 연료펌프에서 발생되는 작동소음이 연료펌프의 바닥면에 대해 일정각도 경사지게 배출되도록 하여 발생된 작동소음이 연료펌프의 바닥면에 반사되면서 외부로 유출되는 양이 감소되도록 하여 전체적으로 연료펌프의 작동소음이 현저히 감쇄되도록 한 연료펌프의 작동소음 감소를 위한 연료펌프 장착구조에 관한것이다.The present invention relates to a fuel pump mounting structure for reducing the operating noise of the fuel pump, in particular, the operating noise generated by the operation noise generated from the fuel pump inclined at an angle to the bottom surface of the fuel pump is the bottom of the fuel pump The present invention relates to a fuel pump mounting structure for reducing operating noise of a fuel pump so that the amount of outflow to the outside as reflected on the surface is reduced, thereby significantly reducing the operating noise of the fuel pump as a whole.

일반적으로 차량에는 엔진의 연소동작에 필요한 연료를 저장하는 연료탱크가 설치되고 있으며, 이러한 연료탱크에는 연료를 펌핑하여 엔진으로 송출하는 연료펌프가 설치되고 있다.In general, a vehicle is provided with a fuel tank for storing fuel required for the combustion operation of the engine, the fuel tank is provided with a fuel pump for pumping the fuel to be sent to the engine.

도 3 은 종래의 연료펌프 장착구조를 도시한 것으로서,Figure 3 shows a conventional fuel pump mounting structure,

연료탱크(1)의 내부에는 연료펌프(4)와 스크린필터(7)를 수용하기위한 리저버컵(8)이 형성되어 있고, 상기 연료탱크(1)의 상단에는 송출파이프(5)의 지지 및 브라켓(3)의 결합을 위한 플레이트(2)가 형성되어 있다.A reservoir cup 8 for accommodating the fuel pump 4 and the screen filter 7 is formed in the fuel tank 1, and the upper end of the fuel tank 1 supports and supports the delivery pipe 5. Plate 2 for coupling the bracket 3 is formed.

상기 플레이트(2)에는 그 직하방을 향하도록 브라켓(3)이 결합되어지며, 상기 브라켓(3)의 끝단에 연료펌프(4)가 수직으로 세워져 장착되고, 여료펌프(4)의 상측으로 연료의 급송을 위한 송출파이프(5)가 연장 형성된다.The plate 2 is coupled to the bracket 3 so as to face directly below, and the fuel pump 4 is vertically mounted at the end of the bracket 3, and the fuel is placed above the filter pump 4. The delivery pipe 5 for feeding of is extended.

상기 연료펌프(4)의 일측으로 입구(6)가 형성되고, 상기 입구(6)에 이물질을 걸러주기 위한 스크린필터(7)가 결합되는 구조이다.An inlet 6 is formed at one side of the fuel pump 4, and the screen filter 7 for filtering foreign matters is coupled to the inlet 6.

이와같이 구성된 종래 연료펌프 장착구조는 엔진구동시 상기 연료펌프(4)가 구동함에 따라 연료탱크(1) 내의 연료가 스크린필터(7)를 통과하여 연료펌프(4) 내부로 유입되고, 이후 연료펌프(4)의 펌핑동작에 의해 송출파이프(5)를 통해 엔진으로 급송되는 것이다.In the conventional fuel pump mounting structure configured as described above, the fuel in the fuel tank 1 flows into the fuel pump 4 through the screen filter 7 as the fuel pump 4 is driven when the engine is driven, and then the fuel pump It is fed to the engine via the delivery pipe 5 by the pumping operation of (4).

그러나, 종래의 연료펌프 장착구조는 연료펌프가 수직방향으로 설치되기 때문에 연료펌프의 작동시 발생하게되는 작동소음이 연료펌프를 통과하여 외부로 유출됨에 따라 차량 외부에 위치하는 사용자에게 큰 소음으로 들리게되어 전체적으로차량의 품질이 저하되는 문제점이 발생하고 있었다.However, in the conventional fuel pump mounting structure, since the fuel pump is installed in the vertical direction, the operation noise generated during the operation of the fuel pump flows out through the fuel pump to the outside, so that the user who is located outside the vehicle can hear a loud noise. There was a problem that the overall quality of the vehicle is deteriorated.

즉, 연료탱크의 플레이트에 장착되는 브라켓의 끝단부가 수직방향으로 세워져 형성되고, 이 부분에 연료펌프가 수직방향으로 장착됨에 따라 연료펌프의 구동시 발생하게되는 작동소음이 도 3 에 도시된 바와같이 연료탱크의 바닥면을 향해 수직방향으로 발생하게되고, 이러한 작동소음이 쉽게 연료탱크의 바닥면을 뚫고 외부로 유출됨에 따라 차량 외부에 위치하는 사용자에게 큰 소음으로 들리게되는 것이다.That is, the end of the bracket mounted on the plate of the fuel tank is formed in the vertical direction, the operating noise generated when the fuel pump is driven as the fuel pump is mounted in the vertical direction as shown in Figure 3 It is generated in the vertical direction toward the bottom of the fuel tank, and this operating noise is easily penetrated to the outside of the fuel tank, and the outside of the vehicle is heard with a loud noise.

특히 차량이 지하주차장이나 주변이 조용한 곳에서 아이들운전상태로 존재할때 상기 연료펌프에서 발생하는 약 6000Hz 대역의 "삑~~ " 하는 작동소음이 연료탱크의 외부로 유출되면서 사용자에게는 큰 소음으로 들리게되어 제품의 품질이 저하되는 것이다.In particular, when the vehicle is in idle operation in the underground parking lot or the surrounding area, the operation noise of about 6000Hz band generated from the fuel pump is leaked to the outside of the fuel tank, which makes a loud noise to the user. The quality of the product is deteriorated.

따라서, 상기 문제점을 해결하기 위한 본 발명은 연료펌프가 장착되는 브라켓을 일정각도 경사지게 설치하고, 그 브라켓에 연료펌프를 장착하므로서, 연료펌프에서 발생되는 작동소음이 연료펌프의 바닥면에 대해 일정각도 경사지게 배출되도록 하여 발생된 작동소음이 연료펌프의 바닥면에 반사되면서 외부로 유출되는 양이 감소되도록 하고, 또한 연료펌프의 직하방에 스크린필터를 설치함에 따라 연료펌프에서 배출되는 작동소음이 스크린필터에 부딪히면서 1차 감쇄되도록 하여 전체적으로 연료펌프의 작동소음이 현저히 감쇄되도록 한 연료펌프의 작동소음 감소를 위한 연료펌프 장착구조를 제공함을 목적으로 한다.Therefore, the present invention for solving the above problems by installing the fuel pump mounting bracket inclined at a certain angle, by mounting the fuel pump on the bracket, the operating noise generated from the fuel pump at a certain angle with respect to the bottom surface of the fuel pump The operating noise generated by the inclined discharge is reflected on the bottom surface of the fuel pump, and the amount of outflow to the outside is reduced. Also, as the screen filter is installed directly under the fuel pump, the operating noise emitted from the fuel pump is screen filter. It is an object of the present invention to provide a fuel pump mounting structure for reducing the operation noise of a fuel pump such that the primary noise is attenuated by hitting the first and thus the operating noise of the fuel pump is significantly reduced.

연료탱크(1)의 상단에 일정두께의 플레이트(2)가 형성되고, 상기 플레이트(2)에는 일정길이의 브라켓(10)을 결합한다.A plate 2 having a predetermined thickness is formed at an upper end of the fuel tank 1, and the plate 10 is coupled to a bracket 10 having a predetermined length.

상기 브라켓(10)은 그 하측이 연료탱크(1)의 바닥부분을 향하도록 하되, 브라켓(10)의 끝단(10a)이 연료탱크(1)의 바닥면에 대해 일정각도, 예를들면 약 15° 경사지도록 형성하는 것이 바람직하다.The bracket 10 has its lower side facing the bottom of the fuel tank 1, with the end 10a of the bracket 10 at an angle to the bottom surface of the fuel tank 1, for example about 15 It is preferable to form so as to be inclined.

그리고, 상기 경사지게 형성된 브라켓(10)의 끝단(10a)에 연료펌프(11)를 장착하므로서, 상기 연료펌프(11)의 작동시 발생하는 작동소음이 연료탱크(1)의 바닥면에 대해 수직으로 배출되지 않고 일정각도를 가지면서 배출되어 작동소음이 연료탱크(1)의 바닥면에 부딪히면서 반사될 수 있도록 하였다.And, by mounting the fuel pump 11 to the end (10a) of the inclined bracket 10, the operating noise generated during operation of the fuel pump 11 is perpendicular to the bottom surface of the fuel tank (1) It is not discharged but discharged at a certain angle so that the operating noise can be reflected while hitting the bottom of the fuel tank (1).

또한 본 발명에서는 상기 연료펌프(11)의 직하방으로 입구(12)를 형성하고, 이 입구(12)에 스크린필터(13)를 결합하므로서, 상기 연료펌프(11)에서 배출되는 작동소음이 스크린필터(13)에 부딪히면서 1차적으로 감쇄되도록 하여 연료탱크(1) 외부로 유출되는 작동소음을 더욱 감소시킬 수 있도록 한 것이다.In addition, in the present invention, by forming the inlet 12 directly below the fuel pump 11, by coupling the screen filter 13 to the inlet 12, the operating noise discharged from the fuel pump 11 screen The primary noise is attenuated while hitting the filter 13 to further reduce the operation noise flowing out of the fuel tank 1.

엔진이 구동함에 연료펌프(11)가 구동하여 연료탱크(1) 내부의 연료를 펌핑하게되고, 상기 연료펌프(11)의 펌핑동작에 의해 연료가 스크린필터(13)를 통해 연료펌프(11) 내부로 유입된 후 연료펌프(11)의 상측으로 형성되는 송출파이프(5)를 통해 엔진으로 공급되게 된다.As the engine is driven, the fuel pump 11 is driven to pump fuel in the fuel tank 1, and fuel is pumped through the screen filter 13 by the pumping operation of the fuel pump 11. After being introduced into the engine, it is supplied to the engine through a delivery pipe 5 formed above the fuel pump 11.

이과정에서 상기 연료펌프(11)에서는 일정크기의 작동소음이 발생하게되는데, 연료펌프(11)에서 발생된 소음은 연료탱크(1)의 바닥면에 수직방향으로 배출되는 것이 아니라 도 2 에 도시된 바와같이 일정각도 경사지게 배출되어 연료탱크(1)의 바닥면에 부딪히게되고, 이에따라 작동소음은 연료탱크(1)의 바닥면을 투과하지 못하고 반사하여 다시 연료탱크(1) 내부로 재유입되므로서 연료탱크(1) 외부로 유출되는 작동소음이 감소하게되는 것이다.In this process, the fuel pump 11 generates a certain amount of operating noise. The noise generated from the fuel pump 11 is not discharged in a direction perpendicular to the bottom surface of the fuel tank 1, but is illustrated in FIG. 2. As it is discharged inclined at an angle to hit the bottom surface of the fuel tank (1), the operation noise is not transmitted through the bottom surface of the fuel tank (1) accordingly reflects and re-introduced back into the fuel tank (1) Therefore, the operating noise flowing out of the fuel tank 1 is to be reduced.

또한, 상기 연료펌프(11)에서 배출되는 작동소음은 입구(12)의 직하방에 결합되어 있는 스크린필터(13)에 부딪히면서 1차 감쇄되므로서, 연료탱크(1)의 바닥면을 투과하는 소음의 양이 현저히 감소하게되는 것이다.In addition, the operation noise discharged from the fuel pump 11 is first attenuated while hitting the screen filter 13 coupled directly below the inlet 12, the noise passing through the bottom surface of the fuel tank (1) The amount of will be significantly reduced.

이상에서 설명한 바와같이 본 발명은 연료펌프가 장착되는 브라켓을 일정각도 경사지게 설치하고, 그 브라켓에 연료펌프를 장착하므로서, 연료펌프에서 발생되는 작동소음이 연료펌프의 바닥면에 대해 일정각도 경사지게 배출되도록 하여 발생된 작동소음이 연료펌프의 바닥면에 반사되면서 외부로 유출되는 양이 감소되도록 하고, 또한 연료펌프의 직하방에 스크린필터를 설치함에 따라 연료펌프에서 배출되는 작동소음이 스크린필터에 부딪히면서 1차 감쇄되도록 하여 전체적으로 연료펌프의 작동소음이 현저히 감쇄되도록 한 연료펌프의 작동소음 감소를 위한 연료펌프 장착구조를 제공하는 효과를 기대할 수 있다.As described above, the present invention installs the bracket on which the fuel pump is mounted at an inclined angle and mounts the fuel pump to the bracket so that the operating noise generated from the fuel pump is inclined at an angle with respect to the bottom surface of the fuel pump. The operating noise generated by the fuel pump is reflected on the bottom of the fuel pump to reduce the amount of outflow. Also, as the screen filter is installed directly under the fuel pump, the operating noise discharged from the fuel pump hits the screen filter. The effect of providing a fuel pump mounting structure for reducing the operating noise of the fuel pump to reduce the operation noise of the fuel pump as a whole to significantly attenuate the overall noise can be expected.
