소음저감형 흡기호스 구조{NOISE CONTROL TYPE INTAKE HOSE STRUCTURE}Noise reduction type intake hose structure {NOISE CONTROL TYPE INTAKE HOSE STRUCTURE}

본 발명은 소음저감형 흡기호스 구조에 관한 것으로서, 보다 상세하게는 자동차용 흡기 시스템에 적용되는 흡기 호스의 소음에 대한 저감 성능을 향상시키기 위한 소음저감형 흡기호스 구조에 관한 것이다.The present invention relates to a noise reduction intake hose structure, and more particularly, to a noise reduction intake hose structure for improving noise reduction performance of an intake hose applied to a vehicle intake system.

일반적으로, 자동차의 흡기 시스템은 엔진으로부터 유입되는 공기를 정화시킴과 더불어, 엔진에서 발생되는 흡기소음을 저감시키기 위한 목적으로 사용된다. In general, the intake system of a vehicle is used for purifying the air flowing from the engine and reducing the intake noise generated in the engine.

이러한 흡기 시스템은 도 1에 도시된 바와 같이, 흡기 호스(Intake Hose)(2)와, 공기 정화기(Air Cleaner)(4), 공기 덕트(Air Duct)(6)로 구성되는 바, 상기 흡기 호스(2)는 구조적으로 단순히 공기만 흐르도록 설계되어 있어서 소음저감 특성이 매우 미약하도록 되어 있다. This intake system is composed of an intake hose (2), an air cleaner (4), an air duct (Air Duct) 6, as shown in FIG. (2) is designed to flow only air structurally, so the noise reduction characteristics are very weak.

상기 흡기 호스의 소음저감 특성에 대한 단점을 해결하기 위해, 최근에는 소음을 저감시키기 위한 별도의 기구를 추가적으로 장착하도록 되어 있는 바, 이는 도 2에 도시된 바와 같다. In order to solve the shortcomings of the noise reduction characteristics of the intake hose, in recent years, a separate mechanism for reducing noise is additionally installed, which is illustrated in FIG. 2.

도 2에 도시된 바에 따르면, 흡기 호스(2)의 소정 부위에 일정한 공간이 확보되어 소음을 제거하는 소음기(또는 공명기)(10)가 클램프(8)를 통해서 고정적으로 삽입되어 고정되고서, 그 소음기(10)가 흡기 호스(2)에서 발생되는 소음을 흡수하여 제거할 수 있도록 되어 있다. As shown in FIG. 2, a silencer (or resonator) 10 for securing a predetermined space in a predetermined portion of the intake hose 2 to remove noise is fixedly inserted and fixed through the clamp 8, and The silencer 10 is configured to absorb and remove the noise generated from the intake hose 2.

그러나, 이러한 종래의 소음기를 갖춘 흡기 호스의 경우에는 흡기 호스와 소음기가 각기 별도의 구조물로 이루어져 있어서 각각 클램프를 통해서 조립할 수 있도록 하고 있기 때문에 생산성이 저하될 수 밖에 없으며, 클램프의 체결이 완전하게 이루어지지 않은 경우에는 소음의 저감성능이 오히려 저하될 수 있게 된다는 문제점이 있다. However, in the case of the conventional intake hose equipped with a silencer, since the intake hose and the silencer are composed of separate structures so that they can be assembled through the clamps, productivity is inevitably reduced, and the clamping is completed completely. If not, there is a problem that the noise reduction performance can be rather deteriorated.

더욱이, 흡기 시스템이 설치되는 엔진룸이 매우 협소함에도 불구하고 별도로 소음기가 설치될 공간을 확보해야 함에 따라, 공간 활용도가 떨어질 뿐만 아니라 차체 설계시에도 제약을 받을 수 있다는 문제점이 있다. Moreover, although the engine room in which the intake system is installed is very narrow, it is necessary to secure a space in which the silencer is to be separately installed, and thus there is a problem that the utilization of space is reduced and the vehicle body design can be restricted.

따라서, 본 발명은 상기한 종래의 문제점을 해결하기 위한 것으로서, 흡기 호스와 일체형으로 이루어지면서 소음저감 성능이 향상되도록 함에 의해, 생산성 향상 및 흡기 시스템의 공간 절감이 가능하도록 하는 소음저감형 흡기호스 구조를 제공하는 것이다.Accordingly, the present invention is to solve the above-mentioned problems, by being made integral with the intake hose to improve the noise reduction performance, noise reduction type intake hose structure to enable improved productivity and space saving of the intake system To provide.

Provide structure.

이하, 상기한 바와 같이 구성된 본 발명에 대해 첨부도면을 참조하여 상세히 설명한다.Hereinafter, the present invention configured as described above will be described in detail with reference to the accompanying drawings.

즉, 도 3은 본 발명에 따른 소음저감형 흡기호스의 구조를 나타낸 도면이다.That is, Figure 3 is a view showing the structure of the noise reduction intake hose according to the present invention.

도 3에 도시된 바와 같이, 본 발명에 따른 소음저감형 흡기호스 구조는 해당 흡기 호스(20)의 일정 지점으로부터 호스를 일정 폭만큼 확장한 호스 확장부(22)를 형성하고, 상기 호스 확장부(22)의 내측으로부터 인너 커버(Inner Cover)(24)를 형성하는 한편, 상기 호스 확장부(22)와 인너 커버(24)의 사이에는 해당 호스 확장부(22)의 내부가 밀폐될 수 있도록 차단하는 격벽(26)이 설치된다. As shown in FIG. 3, the noise reduction intake hose structure according to the present invention forms a hose extension part 22 extending the hose by a predetermined width from a predetermined point of the intake hose 20, and the hose extension part. While forming an inner cover 24 from the inside of the 22, the inner portion of the hose extension 22 can be sealed between the hose extension 22 and the inner cover 24. The partition 26 which blocks is provided.

또한, 상기 인너 커버(24)로부터 호스 확장부(22)까지 상기 격벽(26)에 의한 밀폐공간이 상기 흡기 호스(20)의 내부와 상호 연통될 수 있도록 하기 위해, 상기 인너 커버(24)의 소정부로부터 인출되어 호스 확장부(22)의 내부로 연장되는 일정 길이의 내부 호스(28)를 형성하게 된다. In addition, in order to allow the sealed space by the partition 26 from the inner cover 24 to the hose extension part 22 to communicate with the inside of the intake hose 20, the inner cover 24 may be A predetermined length of the inner hose 28 extending from the predetermined portion and extending into the hose extension 22 is formed.

여기서, 상기 내부 호스(28)의 길이를 상기 호스 확장부(22) 내부에서 증대시켜서 형성하게 되면, 해당 흡기 호스(20)에서 발생되는 저주파성의 소음이 저감되는 반면에, 상기 내부 호스(28)의 길이를 감소시켜서 형성하는 경우에는 해당 흡기 호스(20)의 고주파성의 소음이 저감될 수 있게 되는 바, 상기 흡기 호스(20)에 대해 저감시키고자 하는 소음의 주파수를 알아내고, 그 주파수에 따라 내부 호스(28)의 길이를 조정하여 형성하도록 하는 것이 바람직하다. Here, when the length of the inner hose 28 is formed by increasing the inside of the hose extension 22, the low frequency noise generated by the intake hose 20 is reduced, whereas the inner hose 28 is reduced. In the case of forming by reducing the length of the high frequency noise of the intake hose 20 can be reduced, the frequency of the noise to be reduced with respect to the intake hose 20 is found, and according to the frequency Preferably, the length of the inner hose 28 is adjusted to be formed.

한편, 상기 흡기 호스(20)에 설치되는 호스 확장부(22)와, 인너 커버(24), 격벽(26), 내부 호스(28)는 모두 일체화된 형상을 갖는 금형으로 제작하는 것이 바람직하다. On the other hand, it is preferable that the hose extension portion 22, the inner cover 24, the partition 26, and the inner hose 28 installed on the intake hose 20 are all made of a mold having an integrated shape.

상기한 바와 같이 구성된 본 발명에서는, 자동차용 흡기 시스템의 흡기 호스(20)에 대해 일정 지점으로부터 호스 확장부(22)를 형성하고, 그 호스 확장부(22)의 내측으로부터 인너 커버(24)를 형성하는 한편, 호스 확장부(22)와 인너 커버(24)의 사이에 일정 밀폐공간이 형성되도록 격벽(26)을 설치하고, 해당 흡기 호스(20)의 내부와 호스 확장부(22) 내의 밀폐공간이 상호 연통되도록 인너 커버(24)로부터 홀이 형성된 내부 호스(28)를 인출 형성한다. In the present invention configured as described above, the hose extension portion 22 is formed from a predetermined point with respect to the intake hose 20 of the vehicle intake system, and the inner cover 24 is removed from the inside of the hose extension portion 22. On the other hand, the partition wall 26 is provided so that a predetermined sealed space is formed between the hose extension 22 and the inner cover 24, and the inside of the intake hose 20 and the seal in the hose extension 22 are sealed. The inner hose 28 formed with a hole is drawn out from the inner cover 24 so that the spaces communicate with each other.

이에 따라, 호스 확장부(22)와 인너 커버(24) 사이에 형성된 격벽(26)과 내부 호스(28)에 의해서, 흡기 호스(20)에 의한 소음의 저감 성능이 향상될 수 있게 되고, 저주파성 소음의 저감성능을 향상시키기 위해서는 상기 내부 호스(28)의 길이를 증대시켜서 형성하되, 고주파성 소음의 저감성능을 향상시키기 위해서는 내부 호스(28)의 길이를 감축하여 형성하도록 한다. Accordingly, by the partition 26 and the inner hose 28 formed between the hose extension 22 and the inner cover 24, the noise reduction performance by the intake hose 20 can be improved, and low frequency In order to improve the performance of reducing the noise, the length of the inner hose 28 is increased, but in order to improve the reduction of the high frequency noise, the length of the inner hose 28 is reduced.
