Description

자동차용 연료탱트의 소음저감장치{NOISE REDUCTION DEVICE OF FURE TANK FOR VEHICLE}Noise reduction device for automobile fuel tanks {NOISE REDUCTION DEVICE OF FURE TANK FOR VEHICLE}

본 발명은 자동차에 구비되는 연료탱크에서 발생되는 소음을 감소시키는 장치에 관한 것으로서, 더욱 상세하게는 연료탱크에 보관된 연료가 유동되면서 연료탱크의 내벽과 충돌될 때 발생되는 소음을 감소시키기 위한 자동차용 연료탱크의 소음 저감장치에 관한 것이다.The present invention relates to a device for reducing noise generated in a fuel tank provided in an automobile, and more particularly, to reduce noise generated when a fuel stored in a fuel tank collides with an inner wall of a fuel tank. It relates to a noise reduction device of a fuel tank for fuel.

자동차는 주행하는데 필요한 연료를 보관하기 위해 차체에 연료탱크가 구비되고, 연료탱크에는 자동차가 일정거리 주행할 수 있는 액체 상태의 연료가 저장된다. 연료탱크는 자동차의 종류와 크기에 따라 그 형상이 조금씩 달라지며 차체에 부착되는 위치도 다르다. 통상 연료탱크는 승용차의 경우 실내와 인접한 차체에 부착되고, 화물차의 경우에는 실내와 떨어진 화물칸 부근의 차체에 부착된다.The vehicle is provided with a fuel tank in the body to store the fuel required to drive, the fuel tank is stored in the fuel of the liquid state that can drive the vehicle for a certain distance. The shape of the fuel tank varies slightly depending on the type and size of the car, and the location of the fuel tank is also different. In general, the fuel tank is attached to the vehicle body adjacent to the cabin in the case of a passenger car, and to the vehicle body near the cargo compartment in the case of a truck.

이러한 연료탱크는 액체상태의 연료가 보관되므로 자동차의 주행 속도 및 노면의 상태에 따라서 내부의 연료가 유동하게 되고, 유동하는 연료와 연료탱크 내벽과의 충돌로 인해 소음이 발생된다. 상기 소음은 실내에 인접하게 연료탱크가 설치 되는 승용차에서 더 심하게 느껴진다.Since the fuel tank is a liquid fuel is stored in the fuel according to the driving speed of the vehicle and the state of the road surface, noise is generated due to the collision of the flowing fuel and the inner wall of the fuel tank. The noise is felt more severely in passenger cars with fuel tanks installed adjacent to the room.

특히, 연료탱크를 금속으로 제작하는 경우 금속 특유의 공진영역으로 인해 연료탱크에서는 더 많은 소음이 발생된다. 이를 방지하기 위해 연료탱크를 합성수지로 제작하기도 한다. 그러나 연료탱크를 구성하는 재질을 바꾸더라도 소음이 발생되는 것을 근본적으로 차단할 수는 없으며, 제작비용 및 기술적인 이유 등으로 대부분의 자동차에는 금속으로 제작된 연료탱크가 사용되고 있다.In particular, when the fuel tank is made of metal, more noise is generated in the fuel tank due to the resonance region peculiar to the metal. To prevent this, the fuel tank may be made of synthetic resin. However, even if the material of the fuel tank is changed, noise cannot be fundamentally prevented, and fuel tanks made of metal are used in most automobiles due to manufacturing cost and technical reasons.

이러한 이유로 연료탱크의 내부에는 연료가 유동되는 것을 차단 및 지연하기 위한 배플이 부착된다. 배플은 일종의 차단막으로 연료탱크 내부를 일정 구역으로 분활하여 연료가 유동되는 것을 차단 및 지연한다.For this reason, a baffle is attached inside the fuel tank to block and delay the flow of fuel. The baffle is a kind of barrier that divides the inside of the fuel tank into a certain area to block and delay the flow of fuel.

도 1을 참조하면, 연료탱크(10)에 부착되는 배플(11)은 연료탱크(10)와 유사한 재료인 금속으로 제작되고, 연료탱크(10)와 용접에 의해 결합된다. 이 경우 연료탱크(10)는 연료의 유동에 의해 발생되는 소음은 감소되나 금속 재질인 배플(11)로 인해 무게가 증가하여 자동차의 연비를 떨어트리는 문제가 있다.Referring to FIG. 1, the baffle 11 attached to the fuel tank 10 is made of metal, which is a material similar to that of the fuel tank 10, and is joined to the fuel tank 10 by welding. In this case, the fuel tank 10 has a problem that the noise generated by the flow of the fuel is reduced, but the weight is increased due to the baffle 11 which is a metal material, thereby reducing the fuel economy of the vehicle.

도 2를 참조하면, 이러한 문제점을 감안하여 배플(22)을 합성수지로 제작하는 방법이 제안된다. 그러나 배플(22)을 합성수지로 제작하는 경우에는 금속으로 제작된 연료탱크(20)에 배플(22)을 직접 부착할 수 없으므로, 연료탱크(20)와 배플(22)을 연결할 별도의 체결수단이 필요하다. 이를 해결하기 위해 연료탱크(20)의 내부 상면에는 별도의 체결부(21)를 용접하여 고정한 후 상기 체결부(21)에 배플(22)을 리벳 또는 나사 등의 체결구(23)를 이용하여 고정시킨다. 그러나, 이와 같은 방법은 연료탱크(20)를 조립하는데 많은 시간이 소비되며, 이로 인해 연료탱 크(20)의 제작비가 증가되는 문제점이 있다.Referring to FIG. 2, a method of manufacturing the baffle 22 with a synthetic resin is proposed in view of such a problem. However, when the baffle 22 is manufactured of synthetic resin, the baffle 22 cannot be directly attached to the fuel tank 20 made of metal, so that a separate fastening means connecting the fuel tank 20 and the baffle 22 is provided. need. In order to solve this problem, a separate fastening part 21 is welded and fixed to the inner upper surface of the fuel tank 20, and then the fastening part 23 such as a rivet or a screw baffles 22 is fastened to the fastening part 21. Fix it. However, this method consumes a lot of time to assemble the fuel tank 20, and this causes a problem that the manufacturing cost of the fuel tank 20 is increased.

Thereafter, each fastening groove 311 formed in the fastening surface 310 of the baffle 300 is positioned in the corresponding fixing part 200, and then the fastening part 200 is fastened to be inserted into the fastening groove 311. Pressure in the upward direction is applied to the surface 310. At this time, since the left and right length of the fixing part 200 is larger than the diameter of the fastening groove 311, pressure is applied to the protruding jaw 231 of the elastic locking piece 230. When pressure is applied to the protruding jaw 231 as described above, the protruding jaws 231 and the vertical surface 220 connected to the protruding jaws 231 are also elastically deformed inward. Since the fastening grooves 311 of the fastening surface 310 are positioned in the grooves 233 of the fixing part 200, the pressure applied to the protruding jaw 231 is released, so that the protruding jaws 231 and the vertical surface 220 are Returning to the original state, the fastening groove 311 is caught in the groove 233 of the fixing part 200.

상기와 같이 각각의 고정부(200)에 체결홈(311)이 체결되므로 배플(300)은 연료탱크(100)의 상부에 고정되게 되고, 자동차가 주행시 연료탱크(100) 내부의 연료가 유동되는 것을 방지하여 소음이 발생되는 것을 차단하게 된다.Since the fastening grooves 311 are fastened to the respective fixing parts 200 as described above, the baffle 300 is fixed to the upper portion of the fuel tank 100, and the fuel inside the fuel tank 100 flows when the vehicle is driven. To prevent noise from being generated.
