Description
본 발명은 자동차용 헤드라이너 덕트 기재에 관한 것으로, 더욱 상세하게는 The present invention relates to a headliner duct substrate for an automobile, and in more detail
폴리에스테르와 유리섬유 그리고 부직포를 이용하여 덕트 기재를 제조함으로써, 인체에 무해하면서도 환경친화적일 뿐만 아니라 치수 안정성이 우수하고, 또한 내구성이 뛰어나면서도 가벼워서 차량의 연비 개선에 유리한 자동차용 헤드라이너 덕트 기제에 관한 것이다.By manufacturing the duct base material using polyester, glass fiber, and non-woven fabric, it is harmless to the human body, is environmentally friendly, has excellent dimensional stability, and is excellent in durability and light, so it is suitable for automobile headliner duct base material that is advantageous for improving fuel efficiency of vehicles. About.
대시 보드 안에 장착하여 자동차 실내에 냉·온기를 공급하는 공조장치(때에 따라 자동차 후부에 설치할 수도 있다)는, 일반적으로 앞좌석을 중심으로 냉·온기를 공급할 수 있게 구성하나, 차종에 따라 뒷좌석에서도 냉·온기를 공급할 수 있게 구성한다. 이처럼 뒷좌석에 냉온기를 공급하기 위한 한 가지 방법으로 헤드라이너에 덕트를 장착하고, 이 덕트를 통해 뒷좌석에도 충분한 냉·온기를 공급할 수 있게 제작한다. 아래의 (특허문헌 1) 내지 (특허문헌 3)에는, 이러한 헤드라이너 덕트에 관한 기술이 개시되어 있다.An air conditioner installed in the dashboard to supply cool and hot air to the interior of the car (may be installed at the rear of the car in some cases) is generally configured to supply cool and hot air centering on the front seats, but depending on the vehicle model, it can also be installed in the rear seats It is configured to supply cold and hot air. As one way to supply cold and hot air to the rear seats, a duct is mounted on the headliner, and through this duct, it is manufactured to supply sufficient cold and hot air to the rear seats as well. In the following (Patent Document 1) to (Patent Document 3), techniques relating to such a headliner duct are disclosed.
(특허문헌 1) 한국등록특허 제10-0521879호(Patent Document 1) Korean Patent Registration No. 10-0521879
SUV차량이나 7인승 이상의 차량에 적용되는 에어 덕트 구조에 관한 것이다. 그 구성은, 리어측 승객을 위한 리어 덕트의 기능을 수행하도록 ㄷ자형의 루프레일을 루프패널에 용접으로 고정함으로써, 루프의 강성을 더 보강함은 물론, 에어 덕트의 삭제를 통해 루프의 공간을 최대한 확보하면서 커튼에어백과 FMH용 리브 등의 장착에 따른 실내 헤드 룸의 하강 및 그 하강에 따른 승객의 탑승 불편함을 개선할 수 있도록 하는 루프 멤버를 이용한 에어 덕트 구조를 제공한다.It relates to an air duct structure applied to an SUV vehicle or a vehicle with 7 passengers or more. Its configuration is to further reinforce the rigidity of the roof by fixing the C-shaped roof rail to the roof panel by welding to perform the function of the rear duct for the rear passenger, as well as reducing the space of the roof through the elimination of the air duct. It provides an air duct structure using a roof member to ensure maximum security while improving the lowering of the indoor headroom due to the installation of curtain airbags and ribs for FMH, and improving passenger discomfort due to the lowering.

에어 벤틸레이터 덕트 구조에 관한 것으로, 특히 후방에 설치된 에어컨디셔너에 연결된 에어 벤틸레이터 덕트를 헤드라이닝에 설치하고, 상기 덕트가 전방으로 뻗는 레프트윙과 라이트윙을 구비하도록 하며, 상기 레프트윙과 라이트윙의 전단부와 후단부가 서로 연통하도록 한 에어 벤틸레이터 덕트 구조에 관한 것이다. 이러한 에어 벤틸레이터 덕트 구조는, 후방 에어컨디셔너에 연결되며 헤드라이닝에 설치된 에어 벤틸레이터 덕트에서, 상기 덕트는 후방 에어컨디셔너와 연결되며, 후방으로부터 전방으로 뻗는 레프트윙과 라이트윙을 구비하고, 상기 레프트윙과 라이트윙의 전단부와 후단부에는 각각 2열 에어 벤트와 3열 에어 벤트가 설치되며, 상기 레프트윙과 라이트윙의 후단부는 서로 연통하고, 상기 레프트윙과 라이트윙의 전단부는 관통덕트에 의해 서로 연통하여 있는 것을 특징으로 한다.It relates to an air ventilator duct structure, and in particular, an air ventilator duct connected to an air conditioner installed at the rear is installed on the headlining, and the duct has a left wing and a right wing extending forward, and the front and rear ends of the left wing and the right wing It relates to an air ventilator duct structure in which the parts communicate with each other. This air ventilator duct structure is connected to the rear air conditioner and in the air ventilator duct installed on the headlining, the duct is connected to the rear air conditioner, has a left wing and a right wing extending from the rear to the front, and the front end of the left wing and the right wing. A second row air vent and a third row air vent are installed at the part and the rear end, respectively, the rear ends of the left wing and the right wing communicate with each other, and the front ends of the left wing and the right wing communicate with each other by a through duct.

루프 덕트와 FMH 리브를 일체형으로 제작하므로, FMH 리브가 일체로 이루어진 루프 덕트를 헤드라이너에 장착하는 한 과정을 통해 루프 덕트와 FMH 리브를 동시에 장착하여 헤드라이너 조립 시간을 줄여 생산성을 높이면서도 제조비용도 줄일 수 있게 한다. 특히, 이처럼 FMH 리브를 루프 덕트와 함께 일체로 성형하므로, 루프 덕트와 FMH 리브를 각각 제작하지 않아도 되어 헤드라이너 전체 조립 공정수를 줄이면서도 제조 비용을 줄일 수 있게 한다. 그리고 FMH 리브와 루프 덕트를 사출 성형 방식으로 성형하여 일체로 제작하므로, FMH 리브나 루프 덕트의 형상과 모양이 복잡하더라도 쉽게 제작하여 헤드라이너에 쉽고 신속하게 조립할 수 있게 한다.Since the roof duct and FMH rib are integrally manufactured, the roof duct and FMH rib are mounted at the same time through a single process of attaching the roof duct with the FMH rib to the headliner, reducing the assembly time of the headliner, increasing productivity while increasing manufacturing cost. Make it possible to reduce it. In particular, since the FMH rib is integrally formed with the roof duct, it is not necessary to manufacture the roof duct and the FMH rib, respectively, thereby reducing the number of overall headliner assembly steps while reducing manufacturing cost. In addition, since FMH ribs and roof ducts are molded by injection molding and are integrally manufactured, even if the shape and shape of FMH ribs or roof ducts are complicated, they can be easily manufactured and assembled to the headliner quickly and easily.
한편, 이러한 기존 헤드라이너 덕트는 폴리우레탄 경질 발포체, 폴리프로필렌 수지, 골판지 등을 주로 사용한다. 이때 이들을 부착할 때는 페놀수지계 접착제를 이용함에 따라 다음과 같은 문제가 발생한다.On the other hand, these existing headliner ducts mainly use polyurethane rigid foam, polypropylene resin, corrugated cardboard, and the like. At this time, when attaching them, the following problems arise as a phenolic resin-based adhesive is used.
(1) 페놀수지는 페놀류와 알데하이드류의 축합반응으로 생성한 열경화성 수지의 일종으로, 페놀수지는 소각할 때 미반응이나 불완전 연소로 페놀과 알데하이드가 방출한다. 이러한 페놀과 알데하이드는 작업환경을 포함한 생활환경의 공해물질로 작용하고, 또한 유독성 가스를 배출한다.(1) Phenol resin is a kind of thermosetting resin produced by the condensation reaction of phenols and aldehydes.
