Abstract

The present invention relates to an air duct for vehicles. In traditional ways, productivity is reduced by a decrease of working efficiency as a separate nozzle is joined to the front end of the existing duct, and costs for components are increased by the bolt utilized for joining, and some of air flows out via a gap of a joined portion of the duct and the nozzle. Therefore, the air duct of the present invention includes a nozzle protruding to an indoor space via a rear floor panel for supplying air for cooling and heating for passengers on the back seat. The nozzle (200) which includes a ring-shaped flange (210) to be protruding to an indoor space of a vehicle is formed on the front end of a duct body (100) to be integrated. Foreign material blocking ribs (220) are integrally formed on both sides of the flange (210) to the inside of the nozzle (200). The present invention can omit a separate process of joining the duct body (100) and the nozzle (200) so that costs for components can be reduced as a bolt is not utilized while the productivity is improved. And, the present invention can prevent air from flowing out as no gap between the joined portion of the duct body (100) and the nozzle (200) exists.

자동차용 에어덕트{Air duct of automobile}Air duct of automobile

본 발명은 자동차용 에어덕트에 관한 것으로서 차량의 실내로 바람을 유입시키기 위해 차량 실내로 돌출되는 노즐을 덕트에 일체로 사출 성형하여 덕트와 노즐을 결합하기 위한 별도의 작업공정을 삭제할 수 있음에 따라 생산성 향상은 물론 결합용 볼트를 절약하여 부품비를 절감할 수 있는 것이며, 또한 덕트와 노즐의 결합틈새가 없어 일부 바람이 빠져나가는 현상도 방지할 수 있는 자동차용 에어덕트에 관한 것이다.
The present invention relates to an air duct for an automobile, so that a separate work process for combining the duct and the nozzle may be eliminated by integrally injection molding a nozzle projecting into the vehicle interior to introduce wind into the vehicle interior. In addition to improving productivity, it is possible to reduce the cost of parts by saving the coupling bolt, and also relates to a car air duct that can prevent some wind escapes because there is no coupling gap between the duct and the nozzle.

일반적으로 자동차의 공조장치는 주위의 각종 변화에 따른 온도 및 습도와 공기의 환경을 적당하게 유지함으로서 승차한 사람에게 쾌적한 느낌을 줄 수 있도록 하기 위한 장치로서 차량 외의 시원한 공기를 끌어들여 자동차 실내의 공기와 바꾸어주는 환기장치와 자동차 실내의 온도를 높게 유지시켜 주는 난방장치와, 차 실내의 온도를 낮게 유지시켜 주는 냉방장치로 구분된다.In general, the air conditioner of a car is a device for giving a comfortable feeling to the person riding by maintaining the temperature, humidity, and air environment according to various changes of surroundings. It is divided into a ventilation device to change the temperature, and a heating device to keep the temperature inside the car high, and a cooling device to keep the temperature inside the car low.

따라서 여름에 사용하는 냉방장치로는 카에어컨을 사용하는데 카에어컨은 히터와 쿨러가 일체로 되어있어 이것이 연동하여 공조기능을 발휘하는 형식이고, 겨울에 사용하는 난방장치로는 엔진의 냉각수를 순환시켜 열원으로 하여 작은 라디에이터에 블로어로 공기를 보내 난기를 얻는 온수식 히터장치와 배기가스의 열을 이용한 배기식 히터장치가 있다.Therefore, the air conditioner used in summer uses car air conditioner. The car air conditioner is a type in which the heater and the cooler are integrated so that the air conditioning function is interlocked, and the winter heating device circulates the coolant of the engine. There are a hot water heater device that obtains warm air by blowing air to a small radiator as a heat source and an exhaust heater device that uses heat of exhaust gas.

이처럼 차내에는 계절에 따라 탑승자가 쾌적한 상태에서 여행을 할 수 있도록 냉,난방장치가 설치되어 운전자가 필요에 따라 선택하여 사용토록 하는데 이러한 냉,난방장치를 가동하여 생성되는 찬바람이나 더운 바람은 에어덕트를 통하여 차량의 실내로 들어간다.In this way, the air conditioner is installed in the car so that the passengers can travel in a comfortable state according to the season, so that the driver can select and use it according to the need.The cold wind or hot wind generated by operating the air conditioner is Enters the interior of the vehicle.

즉, 여러 개의 구획칸으로 나누어지고, 에어덕트와 연결되는 노즐이 인스트루먼트패널에 다수 설치되어 냉,난방 바람이 에어덕트와 노즐을 통해 차량의 실내로 유입되어 실내를 시원하게 하거나 따뜻하게 하여 자동차에 탑승한 승객이 여름철에는 더위를 느끼지 않도록 하고 겨울철에는 추위를 느끼지 않도록 하여 쾌적한 여행을 할 수 있는 것이다.That is, it is divided into several compartments, and a number of nozzles connected to the air duct are installed in the instrument panel so that cooling and heating winds flow into the interior of the vehicle through the air duct and the nozzle to cool or warm the room, Passengers do not feel the heat in the summer and do not feel the cold in the winter can be a pleasant trip.

그리고 인스트루먼트패널에 설치된 노즐을 통하여 유입되는 바람만으로는 뒷좌석에 탑승한 승객이 쾌적하지 않을수 있기 때문에 운전석과 조수석 사이에 설치된 콘솔 후미에 노즐을 설치하여 뒷좌석에 탑승한 승객에게 보다 많은 바람을 전달하는 차량도 있다.And because the wind flowing through the nozzles installed in the instrument panel may not be comfortable for passengers in the rear seats, some vehicles deliver more wind to passengers in the rear seats by installing nozzles at the rear of the console installed between the driver's seat and the passenger seat. .

또한, 근래에는 에어덕트를 뒷좌석에 탑승한 승객의 발이 접면되는 리어 플로어패널 저면에 위치되게 하고, 에어덕트와 결합되는 노즐은 리어 플로어패널 상측으로 돌출되도록 한 차량도 있으나 이는 많은 문제점이 있는 것으로서 이를 상세히 설명하면 다음과 같다.In addition, in recent years, the air duct is positioned on the bottom of the rear floor panel where the foot of the passenger occupying the rear seat, and the nozzle coupled with the air duct protrudes to the upper side of the rear floor panel, but there are many problems. It will be described in detail as follows.

Since the work process for coupling the duct body 10 and the nozzle 20 to each other is added, as well as the productivity is lowered as well as there is a problem in that the parts cost due to the use of the bolt (30).

또한, 덕트몸체(10)에 노즐(20)을 서로 결합하는 구조이므로 일부 바람이 덕트몸체(10)와 노즐(20)의 결합 틈새로 빠져나가 즉, 바람의 손실로 인해 실내로 유입되는 바람의 양이 줄어들어 그만큼 냉,난방 효과가 떨어지는 문제점이 있는 것이다.
In addition, since the structure of coupling the nozzle 20 to each other in the duct body 10, some of the wind escapes through the coupling gap between the duct body 10 and the nozzle 20, that is, the wind of the wind flowing into the room due to the loss of wind The amount is reduced, the cooling, heating effect is a problem that falls.

이에 본 발명은 이와 같은 종래의 문제점을 해결하기 위한 것으로 본 발명의 목적은 덕트몸체에 노즐을 일체로 사출 성형하여 덕트몸체와 노즐을 결합하기 위한 별도의 작업공정을 삭제하여 생산성을 향상시키는 것은 물론 이들을 결합할 때 사용하는 볼트를 절약하여 부품비를 절감할 수 있는 자동차용 에어덕트를 제공하기 위한 것이다.
