Description

연료펌프모듈용 커버브라켓의 구조{Structure cover-bracket for fuel pump module}Structure cover bracket for fuel pump module [0001]

본 발명은 연료탱크 내에서 펌프모터와 리저브컵을 결합시키는 연료펌프모듈용 커버브라켓의 구조에 관한 것으로서, 더욱 상세하게는 펌프모터에서 발생하는 소음 및 진동을 감쇄시키도록 절연재를 구비한 연료펌프모듈용 커버브라켓의 구조에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a cover bracket for a fuel pump module for coupling a pump motor and a reservoir cup in a fuel tank, The present invention relates to a structure of a cover bracket.

연료펌프는 리저버컵, 펌프모터, 필터 등이 모듈화되어 연료탱크 내에 장착되며 저장된 연료를 흡입하여 엔진으로 토출시킨다. 연료펌프모듈은 내부에서 (임펠러를 회전시켜) 압력차를 이용해 연료를 토출시킨다. The fuel pump is modularized by a reservoir cup, a pump motor, a filter, etc., mounted in a fuel tank, sucks the stored fuel and discharges it to the engine. The fuel pump module internally discharges the fuel using a pressure differential (rotating the impeller).

즉, 리저버컵에 소정량의 연료가 내부로 유입되면 펌프모터가 압력차를 발생시키켜 송출하되, 필터를 거쳐 불순물이 걸러진 연료는 밸브와 튜브류 등을 통해 엔진으로 송출되는 구조이다. 따라서, 연료펌프모듈은 (연료가 자연기화되어 송출되는) 구형 LPG 차량을 제외한 휘발유 및 경유 차량에는 필수적으로 장착된다. That is, when a predetermined amount of fuel flows into the reservoir cup, the pump motor generates a pressure difference and sends out the fuel. The fuel filtered through the filter is sent to the engine through valves, tubes, and the like. Therefore, the fuel pump module is essentially installed in gasoline and diesel vehicles, except for spherical LPG vehicles (in which fuel is naturally vaporized and delivered).

한편, 차량의 엔진성능 향상에 따라서 (엔진에서) 요구하는 연료공급압력은 증대된다. 가령, 동일한 배기량을 갖더라도 종래의 엔진보다 최근이 출시되는 직분사식 엔진은 요구되는 연료공급압력이 더 크다.On the other hand, the fuel supply pressure required by the engine increases as the engine performance of the vehicle improves. For example, even with the same displacement, a direct injection engine that is released more recently than a conventional engine requires a greater fuel supply pressure.

따라서, 연료펌프의 요구되는 출력 또한 더욱 커지고 있다. 그러나, 연료펌프의 용량 및 출력 증대는 펌프모터의 작동에 따라 유발되는 진동 및 소음을 증가시키는 문제점이 있었다.
Therefore, the required output of the fuel pump is also getting larger. However, there has been a problem in that the capacity and the output increase of the fuel pump increase the vibration and noise caused by the operation of the pump motor.

즉, 도 1 에 도시된 바와 같이, 펌프모터의 작동에 따라 발생하는 소음 및 진동은 커버브라켓을 통하여 리저버컵, 지지바와 스프링, 플랜지, 쿠션 및 튜브류와 연료를 거쳐 연료탱크로 전달되며 차량 내부로 유입되는 문제점이 있었다.1, the noise and vibration generated by the operation of the pump motor are transmitted to the fuel tank through the reservoir cup, the support bar, the spring, the flange, the cushion and the tubes and the fuel through the cover bracket, .

따라서, 커버브라켓은 펌프모터를 리저버컵에 견고하게 고정시켜야 할 뿐만 아니라 진동 및 소음을 절연하는 기능이 동시에 요구되었다. 그러나, 종래의 커버브라켓은 링 형상으로서 펌프모터가 장착되도록 센터홀이 형성되고 둘레를 따라 "∩" 모양의 홀더가 다수 개 부설되어 리저버컵의 상단에 끼워질 수 있도록 구성었으나, (사출성형 등을 통하여) 상기 홀더는 일체로 커버브라켓에 형성되었었다.Therefore, the cover bracket not only has to firmly fix the pump motor to the reservoir cup, but also has a function of insulating vibration and noise. However, in the conventional cover bracket, a center hole is formed so that the pump motor is mounted as a ring shape, and a plurality of "∩" shaped holders are provided along the periphery so as to be fitted to the upper end of the reservoir cup. The holder was integrally formed in the cover bracket.

따라서, 본 발명은 견고한 고정 구조를 갖되 펌프모터에서 발생하는 진동 및 소음의 전달을 효율적으로 억제할 수 있는 연료펌프모듈용 커버브라켓의 구조를 제공하는 것에 주목적이 있다.
SUMMARY OF THE INVENTION Accordingly, it is a primary object of the present invention to provide a structure of a cover bracket for a fuel pump module which has a rigid fixing structure and is capable of effectively suppressing transmission of vibration and noise generated in a pump motor.

상기와 같은 목적을 달성하기 위한 본 발명은, 펌프모터에 결합되어 상기 펌프모터를 리저브컵에 안착시키도록, 몸체에는 펌프모터가 거치되는 센터홀을 형성되고, 리저브컵에 끼워지는 하나 이상의 홀더가 몸체의 둘레를 따라 결합되는 연료펌프모듈용 커버브라켓의 구조에 있어서, 상기 홀더와 몸체 사이에는 탄성 재질의 절연재가 장착되되, 상기 절연재의 일측은 홀더에 구속되고 타측은 몸체에 구속되어 상기 홀더가 절연재를 통하여 몸체에 결합되는 것을 특징으로 한다.According to an aspect of the present invention, there is provided a pump for a motor, comprising: a center hole coupled to a pump motor for seating the pump motor in a reservoir cup; and at least one holder A cover bracket for a fuel pump module according to claim 1, wherein an insulating material of elastic material is mounted between the holder and the body, one side of the insulating material is constrained to the holder and the other side is constrained to the body, And is coupled to the body through an insulating material.

상기 몸체에는 중앙에 제1끼움홈이 형성된 몸체거치부가 돌출되고 상기 홀더에는 중앙에 제2끼움홈이 형성된 홀더거치부가 돌출되며, 상기 절연재는 제1끼움홈과 제2끼움홈으로 진입하여 몸체거치부 및 홀더거치부에 끼워져 거치도록 양단은 각각 걸림턱이 형성된다.A body mounting portion formed with a first fitting groove at the center thereof is protruded and a holder mounting portion having a second fitting groove formed at the center thereof is protruded from the body and the insulating material is inserted into the first fitting groove and the second fitting groove, Both end portions of the engaging protrusions are formed so as to be inserted into the fitting portion and the holder mounting portion, respectively.

상기 걸림턱은 절연재의 양단에서 서로 대향하여 배치되되 "T" 모양 이루도록 형성되고, 양측의 걸림턱들 사이에는 탄성변형을 유도하도록 주름진 형상으로 탄성유도부가 형성된다.The latching jaws are formed so as to be opposed to each other at both ends of the insulating material so as to have a "T" shape, and between the latching jaws at both sides, an elastic guide portion is formed in a corrugated shape to induce elastic deformation.

그리고, 상기 몸체거치부 및 홀더거치부의 끝단에는 절연재의 이탈을 방지하도록 스토퍼부가 돌출된다.A stopper portion is protruded from the end of the body mounting portion and the holder mounting portion to prevent the insulating material from coming off.

아울러, 상기 홀더와 몸체 사이가 이격되도록 절연재의 일측 및 타측에는 간섭방지돌기가 돌출된다.
In addition, interference preventing protrusions protrude from one side and the other side of the insulating material so that the holder and the body are separated from each other.

상기와 같은 구성의 본 발명은, 홀더가 몸체에서 분리제조되어 결합되되 그 사이에 절연재가 삽입되어 펌프모터에서 발생하는 소음과 진동의 전달을 억제할 수 있는 효과가 있다.According to the present invention as described above, there is an effect that the holder is separated from the body and coupled, and an insulating material is inserted therebetween, thereby suppressing the transmission of noise and vibration generated in the pump motor.

상기 절연재는 양단에 걸림턱이 형성된 구조로서 홀더와 몸체의 조립시 용이하게 삽입결합될 수 있는 효과가 있다. 그리고, 상기 걸림턱은 주름진 형상의 탄성유도부가 형성되어 모터의 진동을 더 효율적으로 감쇠시킬 수 있는 효과가 있다.The insulating material has a structure in which the latching jaws are formed at both ends of the insulating material, so that the insulating material can be easily inserted and bonded when the holder and the body are assembled. Further, the engaging jaw is formed with a corrugated elastic guide portion, so that vibration of the motor can be more effectively attenuated.

아울러, 몸체거치부 및 홀더거치부의 끝단에는 스토퍼부가 각각 돌출되어 진동에 따라 유발될 수 있는 절연재의 이탈을 방지할 수 있다. 그리고, 절연재가 (홀더 및 몸체와) 접촉하는 부분에는 간선방지돌기가 형성되어 각 부품치수의 공차 및 조립 공차로 인한 간섭을 방지하며 접촉면적으로 최소화하여 절연성능을 향상시킬 수 있다.
In addition, a stopper portion may protrude from the end of the body mounting portion and the holder mounting portion to prevent the insulating material, which may be caused by vibration, from being separated. In addition, an anti-fouling protrusion is formed at a portion where the insulation material contacts (the holder and the body), thereby preventing interference due to tolerances and assembly tolerances of each component, and minimizing the contact area.
