Description
본 발명은 차량의 엔진에서 발생되는 소음을 차단하고자 엔진의 밑면에 설치되는 언더 커버에 관한 것으로, 특히 구조가 간단하고 차음 및 흡음성능이 뛰어나며 제조원가를 현저하게 절감할 수 있는 차량 엔진용 언더 커버에 관한 것이다.The present invention relates to an under cover installed on the underside of an engine to block noise generated from an engine of a vehicle, and particularly, to an under cover for a vehicle engine that is simple in structure, excellent in sound insulation and sound absorption, and which can significantly reduce manufacturing costs. It is about.
일반적으로 트럭 등과 같은 대형 차량의 엔진에는 그 엔진의 구동에 따른 소음을 차단하고자 엔진의 밑면에 언더 커버를 설치하는데, 이를 첨부된 도면 도 2를 참고하여 설명하면 다음과 같다.In general, in the engine of a large vehicle such as a truck, an under cover is installed on the underside of the engine to block noise caused by the driving of the engine, which will be described with reference to the accompanying drawings.
도시된 바와 같이, 차량(1)의 엔진(2)의 밑면에 차음 및 흡음을 위해 설치되는 종래의 언더 커버(50)는 플라스틱 등과 같은 합성수지로 성형된 커버판(52)의 일면으로 일정 두께를 갖도록 발포우레탄 등으로 성형되는 흡음재(55)가 양면 테이프(54) 등으로 부착되어 지고, 그 흡음재(55)의 표면에는 다시 알루미늄 테이프(56) 등이 접착되도록 구성된다.As shown, the conventional undercover 50 installed on the underside of the engine 2 of the vehicle 1 for sound insulation and sound absorption has a predetermined thickness on one surface of the cover plate 52 formed of synthetic resin such as plastic. The sound absorbing material 55 formed of foam urethane or the like is attached to the double-sided tape 54 or the like, and the aluminum tape 56 or the like is adhered to the surface of the sound absorbing material 55 again.
상기와 같이 구성되는 종래의 언더 커버는 커버판과 양면 테이프 사이에 엔진에서 발생된 소음을 차음 및 흡음할 수 있도록 하는 일정두께 약 15mm의 발포우레탄으로 성형된 흡음재가 부착되어 있어서, 그 무게가 무거울 뿐만 아니라 그에 따른 설치의 번거러움 등의 여러 문제점이 발생하였다.The conventional undercover configured as described above has a sound absorbing material formed of a foamed urethane having a thickness of about 15 mm attached to the cover plate and the double-sided tape to enable sound insulation and sound absorption from the engine, so that its weight is heavy. In addition, a number of problems, such as the hassle of installation accordingly occurred.
또한, 구조가 복잡하여 즉, 커버판과 양면테이프와 흡음재 및 알루미늄 테이프 등으로 이루어짐에 따라 제작이 불편한 문제점도 발생하였다.In addition, since the structure is complicated, that is, made of a cover plate, a double-sided tape, a sound absorbing material, and an aluminum tape, there is a problem in that the production is inconvenient.
그리고, 상기 흡음재는 비교적 단가가 높은 발포우레탄으로 성형됨에 따라 그 언더 커버의 제조단가 역시 자연적으로 높아 지는 문제점 또한 초래되었다.In addition, as the sound absorbing material is molded from a relatively high cost polyurethane foam, the manufacturing cost of the under cover also naturally caused a problem.
상기와 같은 종래의 제반 문제점을 해소하고자 안출한 것으로,In order to solve the above conventional problems,
본 발명의 목적은 구조가 간단하고 차음 및 흡음성능이 뛰어나며 제조원가를 현저하게 절감할 수 있는 차량 엔진용 언더 커버를 제공하는 데 있다.It is an object of the present invention to provide an under cover for a vehicle engine that is simple in structure, excellent in sound insulation and sound absorption, and which can significantly reduce manufacturing costs.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참고하여 더욱 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention will be described in more detail.
도 1은 본 발명의 요부를 도시한 단면도이다.1 is a cross-sectional view showing the main part of the present invention.
도시된 바와 같이, 차량(1)의 엔진(2)에서 발생되는 소음을 차단하기 위해 엔진의 밑면으로 덮혀지는 합성수지재로 성형된 커버판(52)을 구비한 차량 엔진용 언더 커버(50)에 있어서,As shown, the under cover 50 for a vehicle engine having a cover plate 52 formed of a synthetic resin material covered with the underside of the engine to block noise generated by the engine 2 of the vehicle 1. In
본 발명은 상기 커버판(52)의 일면에 부착되는 다수의 부착부(12)와, 부착부(12) 사이에 공기가 충진되도록 돌출 형성되는 다수의 공기충진부(15)로 구성되며, 폴리에틸렌수지(PE) 등과 같은 열경화성 합성수지 필름으로 성형되어 일반적인 부착방식인 접착재 등으로 상기 부착부(12)가 커버판(52)에 부착되어지는 차단부재(10)를 구비한 차량 엔진용 언더 커버를 제공한다.The present invention is composed of a plurality of attachment portions 12 attached to one surface of the cover plate 52, and a plurality of air filling portions 15 protruded to fill air between the attachment portions 12, polyethylene Provided is an undercover for a vehicle engine having a blocking member 10 formed of a thermosetting synthetic resin film such as resin (PE) and the like, wherein the attachment part 12 is attached to the cover plate 52 by an adhesive material, which is a general attachment method. do.
상기에서, 커버판(52)의 일면에 부착되는 차단부재(10)는 접착재로 부착하는방식 이외에 일반적인 융착방식인 열융착이나 고주파 융착방식으로 부착하여도 무방하다.In the above description, the blocking member 10 attached to one surface of the cover plate 52 may be attached by heat fusion or high frequency fusion, which is a general fusion method, in addition to the adhesive method.
상기와 같이 커버판(52)의 일면으로 다수의 공기충진부(15)가 형성된 차단부재(10)가 그 공기충진부 사이에 형성된 부착부에 의하여 부착되어 짐에 따라, 엔진이 구동되면서 발생되는 소음이 상기 공기충진부에 충진된 공기에 의해 상쇄되어져 소멸됨으로써, 소음을 차단하게 되는 것이다.As the blocking member 10 having a plurality of air filling parts 15 formed on one surface of the cover plate 52 is attached by an attachment part formed between the air filling parts, the engine is generated while driving. The noise is canceled by the air filled in the air filling unit and disappears, thereby blocking the noise.
또한, 상기 차단부재는 돌출되도록 형성되는 공기충진부와 상기 커버판에 부착되는 부착부로 구성됨에 따라 소음의 접촉단면적을 최대한 확보할 수 있어 발생소음의 흡음성능 또한 뛰어난 것이다.In addition, since the blocking member is composed of an air filling portion formed to protrude and an attachment portion attached to the cover plate, it is possible to secure the maximum contact cross-sectional area of noise, so that the sound absorbing performance of the generated noise is also excellent.
따라서, 엔진에서 발생되는 소음을 상기 공기충진부에서 상쇄시키고, 소음의 접촉단면적을 최대한 확보함에 따라 엔진 구동에 따른 소음을 최소화할 수 있는 조건을 구비하게 되는 것이다.Therefore, the noise generated by the engine is canceled by the air filling unit, and the contact area of the noise is secured to the maximum, thereby providing a condition capable of minimizing the noise caused by driving the engine.
이상과 같은 본 발명의 차량용 엔진 언더커버는 엔진에서 발생되는 소음을 최소화하기 위하여, 커버판 일면으로 부착되는 부착부와 다수의 공기충진부를 포함하여 구성되는 차단부재를 구비함에 따라, 구조가 간단하면서 엔진에서 발생되는 소음을 공기충진부에서 상쇄시키고 소음의 접촉단면적을 최대한 넓게 확보함에 따라 엔진으로부터 발생되는 소음을 최소화할 수 있는 효과를 가지게 되는 것이다.As described above, the vehicle engine undercover of the present invention has a blocking member including an attachment part attached to one surface of the cover plate and a plurality of air filling parts in order to minimize noise generated from the engine. The noise generated by the engine is offset by the air filling unit and the contact area of the noise is secured as wide as possible to have the effect of minimizing the noise generated from the engine.
또한, 커버판과 이에 부착되는 차단부재 만으로 언더커버를 구성함에 따라 무게가 가벼워 설치가 손쉽게 이루어짐은 물론 제조원가 또한 현저하게 절감할 수있는 효과도 가지게 되는 것이다.In addition, as the undercover is composed only of the cover plate and the blocking member attached thereto, the weight is light, so that the installation is easily performed, and the manufacturing cost is also significantly reduced.
