Description
본 발명은 소음저감구조의 엔진언더커버에 관한 것으로 더욱 상세히는 차량이 주행됨에 따라 엔진 하부로 흐르는 기류의 방향을 기류의 방향을 상향으로 절환시켜 엔진블럭에 부딪히도록 유도함으로써, 엔진냉각 효율을 증대시킬 수 있도록 함과 동시에 엔진의 구동소음을 저감시키킬 수 있는 기능이 병행되도록 한 소음저감구조의 엔진언더커버에 관한 것이다.The present invention relates to an engine undercover having a noise reduction structure. More specifically, the engine cooling efficiency is improved by inducing the airflow flowing under the engine to be bumped into the engine block by upwardly changing the direction of the airflow as the vehicle travels. The present invention relates to an engine undercover having a noise reduction structure which allows a function of reducing the driving noise of the engine while being able to increase it.
일반적으로 차량의 엔진룸의 하부는, 엔진의 소음을 차단하고, 외부로부터 엔진블럭에 가해지는 직접적인 충격을 차단시키고 이물질이 엔진룸으로 유입되는 것을 방지하기 위하여 섀시프레임에 연장, 결합시킨 구조로 형성되어 있다.In general, the lower part of the engine room of the vehicle is formed of a structure that is extended and coupled to the chassis frame to block the noise of the engine, block direct shocks applied to the engine block from the outside, and prevent foreign matter from entering the engine room. It is.
상기한 바와 같은 언더커버는 제1도(제1도)에 도시된 바와 같이 섀시프레임에 커버프레임(10)을 연장, 결합시키고, 이 커버프레임(10)에 커버플레이트(20)을 연장시킨 구조로 되어 있으며, 상기 커버플레이트(20)은 소정 간격으로 배치되는 위치에 밴딩부(21)을 형성하여 커버플레이트(20)이 차량의 주행진동 및 엔진의 구동진동에 따라 울렁거리게 되는 것을 방지할 수 있도록 하고 있다.The undercover as described above has a structure in which the cover frame 10 is extended and coupled to the chassis frame and the cover plate 20 is extended to the cover frame 10 as shown in FIG. The cover plate 20 may be formed in a bending portion 21 at positions disposed at predetermined intervals to prevent the cover plate 20 from rumbling due to driving vibration of the vehicle and driving vibration of the engine. To make it work.
즉, 이와 같이 커버플레이트(20)으로 형성되는 다수 벤딩부(21)는 커버플레이트(20) 자체를 보강하게 됨으로써, 각종 진동에 따라 커버플레이트(20)이 울렁거리게 되는 것을 방지하고, 울렁거림에 따라 소음이 발생되는 것을 원칙적으로 방지할 수 있도록 하고 있다.That is, the plurality of bending portions 21 formed as the cover plate 20 in this way to reinforce the cover plate 20 itself, thereby preventing the cover plate 20 from rumbling in response to various vibrations, Therefore, the noise can be prevented in principle.
그러나, 이러한 종래의 언더커버는 엔진룸 내부의 더운 공기를 외부로 유출시킬 수 없으며, 따라서 엔진블럭의 냉각효율이 저하된다는 문제점이 있었다.However, such a conventional undercover cannot leak hot air to the outside of the engine room, thereby reducing the cooling efficiency of the engine block.
뿐만 아니라, 엔진으로부터 발생되는 구동소음이 언더커버의 커버프레이트에 부딪혀 반사되고, 또 커버플레이트를 울리므로 엔진의 구동소음을 저감시킬 수 없게 된다는 단점이 있었다.In addition, the driving noise generated from the engine hits the cover plate of the undercover and is reflected, and also has a disadvantage that the driving noise of the engine cannot be reduced because the cover plate sounds.
본 발명은 상기한 바와 같은 종래의 문제점 및 단점을 해소하기 위하여 안출된 것으로 본 발명의 목적은 엔진블럭에 부딪히는 공기량을 증대시켜 엔진블럭을 냉각시키기 위한 효율을 극대화함은 물론, 엔진의 구동소음을 저감시킬 수 있는 소음저감구조의 엔진언더커버를 제공하려는데 있다.The present invention has been made in order to solve the problems and disadvantages of the prior art as described above, the object of the present invention is to increase the amount of air that hits the engine block to maximize the efficiency for cooling the engine block, as well as driving noise of the engine It is to provide an engine undercover with a noise reduction structure that can be reduced.

이를 실현시키기 위한 본 발명은, 엔진블럭이 안착 상태로 장착되는 소음저감구조의 엔진언더커버에 있어서, 차량의 섀시프레임에 연장, 결합되는 커버프레임; 대략 'ㄷ'자의 형상으로 형성되어 상기 커버프레임의 하부로 돌출되도록 연장, 결합되는 커버플레이트; 상기 커버플레이트로부터 절개되어져서 절개면으로부터 예각을 이루도록 절곡되는 다수개의 기류안내편; 및 상기 다수 방열편면에 부착되는 다수 흡음재를 포함하여 구성되는 소음저감구조의 엔진언더커버를 제공한다.According to an aspect of the present invention, there is provided an engine under cover of a noise reduction structure in which an engine block is mounted in a seated state, the cover frame extending and coupled to a chassis frame of a vehicle; A cover plate which is formed in a shape of an approximately 'c' and extends and is coupled to protrude to the bottom of the cover frame; A plurality of airflow guide pieces which are cut out from the cover plate and bent to form an acute angle from the cut surface; And a plurality of sound absorbing materials attached to the plurality of heat dissipating one surfaces.
이러한 구성에 따라 본 발명은, 커버플레이트의 내측으로 유입되어 흐르는 공기의 흐름방향을 절환시켜 그 만큼 많은 양의 공기가 엔진블럭에 부딪히게 되므로 현저하게 증대된 엔진 냉각효과를 기대할 수 있게 됨은 물론, 엔진의 구동소음을 흡수시킬 수 수단으로 흡음재가 각 기류안내편에 부착되어 있으므로 엔진으로부터의 구동소음을 저감시키기에 되는 것이다.According to this configuration, the present invention, by switching the flow direction of the air flowing into the inside of the cover plate so that a large amount of air hits the engine block can be expected to significantly increase the engine cooling effect, of course, As a sound absorbing material is attached to each air flow guide piece as a means for absorbing driving noise of the engine, driving noise from the engine is reduced.
이하, 본 발명의 바람직한 실시예를 첨부한 도면에 따라서 더욱 상세히 설명하며, 종래의 동일한 부분에 대하여는 동일한 부호를 부여하기로 한다.Hereinafter, a preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings, the same reference numerals will be given to the same parts in the prior art.
본 발명의 일 실시예는 엔진의 구동 소음을 제거하고, 외부로부터 엔진블럭에 가해지는 직접적인 충격을 차단시킴과 동시에 이물질이 엔진룸으로 유입되는 것을 방지하기 위하여 언더커버를 섀시프레임에 연장, 결합시킨 구조로 엔진룸의 하부에 구성되는 엔진의 언더커버에 관련된다.One embodiment of the present invention is to remove the driving noise of the engine, to block the direct impact applied to the engine block from the outside and at the same time extend and combine the undercover to the chassis frame to prevent foreign matter from entering the engine room The structure relates to the undercover of the engine, which is configured at the bottom of the engine compartment.
상기한 바와 같은 언더커버는 도2(제2도) 및 도3(제3도)에 도시된 바와 같이 섀시프레임에 커버프레임(10)을 연장.결합시키고, 이 커버프레임(10)에 커버플레이트(20)을 연장시킨 구조로 되어 있다.The undercover as described above extends and couples the cover frame 10 to the chassis frame, as shown in FIGS. 2 (2) and 3 (3), and the cover plate to the cover frame 10. (20) is extended.
한편, 차량의 주행될 때 엔진룸의 하부의 커버플레이트(20) 안측에서 차량의 진행 반대 방향으로 흐르게 되는데, 이러한 공기는 상기한 커버프레임(10)에 절개 형성된 다수 기류안내편(30)에 의해 엔진룸으로 유입된 후 엔진블럭에 곧 바로 부딪히게 된다.On the other hand, when the vehicle travels, the inside of the cover plate 20 in the lower portion of the engine room flows in the opposite direction of the vehicle, and this air flows by the plurality of airflow guide pieces 30 formed in the cover frame 10 described above. After entering the engine room, it immediately hits the engine block.
즉, 차량의 섀시프레임에 커버프레임(10)이 연장, 결합되고 이 커버프레임(10)에는 대략 'ㄷ'자의 형상으로 커버플레이트(20)가 하부로 돌출되도록 결합되며, 이러한 커버플레이트(20)로부터 다수개의 기류안내편(30)이 절개되어 져서 절개면으로부터 예각을 이루도록 절곡되어 있다.That is, the cover frame 10 extends and is coupled to the chassis frame of the vehicle, and the cover plate 10 is coupled to the cover frame 10 such that the cover plate 20 protrudes downward in a shape of 'c', and the cover plate 20 is connected to the cover frame 20. A plurality of airflow guide pieces 30 are cut out from each other and are bent to form an acute angle from the cut surface.
한편, 상기 다수의 기류안내편(30)에는 기류안내측 면으로 흠음재(31)가 부착되어 있어 엔진 구동에 따른 소음이 흡수될 수 있도록 하고 있으며, 미설명 부호 '22'는 상기 기류안내편(30)이 절개됨에 따라 뚫리게 되는 구멍을 나타내고 있다.On the other hand, the plurality of airflow guide piece 30 is attached to the air flow guide side surface flap material 31 so that the noise due to the engine driving can be absorbed, reference numeral '22' is the airflow guide piece It shows the hole to be drilled as 30 is cut.
이와 같은 구성에 따라 본 발명은 커버플레이트(20)의 내측으로 유입되어 흐르는 공기의 흐름방향을 절환시켜 그 만큼 많은 양의 공기가 엔진블럭에 부딪히게 되므로 현저하게 증대된 엔진 냉각효과를 기대할 수 있게 됨은 물론, 흡음재(31)가 각 기류안내편(30)에 부착되어 있으므로 엔진으로부터 구동소음을 흡수, 저감시킬 수 있게 된다.According to this configuration, the present invention switches the flow direction of the air flowing into the cover plate 20 so that a large amount of air collides with the engine block, so that the engine cooling effect can be significantly increased. Of course, since the sound absorbing material 31 is attached to each airflow guide piece 30, it is possible to absorb and reduce driving noise from the engine.
상기 본 발명에 의한 소음저감구조의 엔진언더커버는, 엔진블럭에 부딪히는 공기량을 증대시켜 엔진블럭을 냉각시키기 위한 효율을 극대화시킬 수 있게 됨은 물론, 엔진의 구동소음을 저감시킬 수 있다는 이점이 있다.The engine undercover of the noise reduction structure according to the present invention has the advantage of being able to maximize the efficiency for cooling the engine block by increasing the amount of air hitting the engine block, as well as reducing the driving noise of the engine.
