본 발명은 차량용 에어벤트의 풍향자동변환장치에 관한 것이다.The present invention relates to a wind direction automatic conversion device for a vehicle air vent.

차량은 크래쉬 패드의 중앙부와 양측면에 에어벤트를 설치하여 공기조화장치에서 생성된 온풍 또는 냉풍을 블로워에 의하여 덕트를 통하여 에어벤트에 토출하므로서 실내의 냉난방을 실시하고 있다. 그러나 종래의 에어벤트는 하우징에 노즐을 그 외면 양측에 형성된 지지핀으로 상하 회전할 수 있게 설치하고, 노즐내면의 상하에 지지공을 형성하여 수개의 윙을 그 상하단에 형성된 지지핀으로 중앙의 윙에 형성된 노브에 의향 좌우 회전할 수 있게 설치한 것이다.In the vehicle, air vents are installed at the center and both sides of the crash pad to discharge the warm air or cold air generated by the air conditioner to the air vent through the duct by a blower, thereby cooling the room. However, the conventional air vent is installed in the housing so that the nozzle can be rotated up and down with support pins formed on both sides of the outer surface, and a support hole is formed on the upper and lower sides of the nozzle inner surface so that several wings are formed by the support pins formed at the upper and lower ends thereof. It is installed to be rotated left and right to the knob formed in the.

따라서 풍향을 상하조절하기 위하여 노즐을 전후로 회전 조작하면 노즐의 외면이 하우징의 내면과 접촉되어 그 조절위치가 고정되고, 풍향을 좌우 조절할 때에는 윙의 중앙에 형성된 노브에 의하여 윙을 좌우 회전하는 것이므로 풍향 조절시마다 노즐 또는 노브를 회전 조작하므로 불편하고, 또한 노즐과 하우징의 접촉강도 또는 윙의 상하에 형성된 지지핀과 노즐의 내면에 형성된 지지공의 지지강도가 작을 때에는 차량의 주행시에 발생되는 진동 또는 충격에 의하여 조절된 풍향이 변동되어 실내의 공기조화가 균일하게 되지못할 뿐 아니라 토출 공기가 오랫동안 탑승자의 얼굴 등에 부딪칠 경우에는 탑승감이 좋지못한 문제점이 있는 것이다.Therefore, if the nozzle is rotated back and forth to adjust the wind direction up and down, the outer surface of the nozzle is in contact with the inner surface of the housing, and the adjustment position is fixed. When adjusting the wind direction, the wing is rotated left and right by a knob formed at the center of the wing. It is inconvenient because the nozzle or knob is rotated every time the adjustment is inconvenient. Also, when the contact strength between the nozzle and the housing or the support pin formed on the upper and lower sides of the wing and the support hole formed on the inner surface of the nozzle is small, vibration or shock generated when the vehicle is running If the wind direction is adjusted by the fluctuation of the indoor air conditioning is not uniform, and if the discharged air hits the face of the occupant for a long time, there is a problem that the boarding feeling is not good.

상기한 문제점을 시정하기 위하여 덕트에 팬을 설치하여 블로워에서 발생된 풍압에 의하여 이를 회전시키고, 상기 팬의 회전력을 감속기에서 감속한 후 왕복운동으로 변환하는 크랭크 기구에 전달하며, 상기 크랭크 기구를 윙에 연결된 링크를 연결하여 윙을 회전시키며 상기 링크와 크랭크 기구를 수동 노브에 의하여 단속하므로서 별도의 전력을 소비하지 않고 윙을 자동으로 좌우 회전토록한 스윙 그릴이 일본국 발명협회 공개기보 87-3816에 개시된 바 있다.In order to correct the above problems, a fan is installed in the duct to rotate it by the wind pressure generated by the blower, and the rotational force of the fan is decelerated in the reducer and transmitted to the crank mechanism that converts into reciprocating motion, and the crank mechanism is winged. The swing grille which rotates the wing by connecting the link connected to it and rotates the wing automatically left and right without consuming extra power by intermittently controlling the link and the crank mechanism by the manual knob is disclosed in JP 87-3816. It has been disclosed.

그러나 상기한 스윙 그릴은 동력 전달기구가 복잡하여 마찰 손실이 크게되므로 블로워를 저속회전시킬 때에는 윙의 풍향조절이 곤란하고, 윙의 회전 및 정지조작이 번잡한 문제점이 있는 것이다.However, the swing grille has a problem in that it is difficult to control the wind direction when the blower is rotated at low speed because the power transmission mechanism is complicated and friction loss is large, and the rotation and stop operation of the wing is complicated.

본 발명은 상기한 문제점을 시정하여 덕트 내의 풍압으로 노즐의 토출 풍향을 원활하기 변환되게 하고, 노즐의 회전 및 정지를 편리하게 한 차량용 에어벤트의 풍향자동변환장치를 제공하는 것을 목적으로 한다.An object of the present invention is to provide an automatic wind direction converting device for a vehicle air vent, which smoothly converts the discharge wind direction of the nozzle by the wind pressure in the duct to correct the above problems, and facilitates the rotation and stop of the nozzle.

본 발명은 상기한 목적을 달성하기 위하여 덕트에 회전축의 양단이 지지되고 회전축의 일단에 구동기어가 고정된 팬과, 상기 팬의 회전력에 의하여 좌우 조절되는 노즐을 구비한 것에 있어서, 상기 덕트에 지지되고 상기 구동기어와 치합되거나 분리되는 종동기어와 원통캠이 형성된 캠축과, 상기 캠축에 회전이 자유롭게 설치한 조작봉과, 상기 원통캠에 접촉되게 설치한 종동절 및 상기 종동절에 연결된 노즐로 구성한 것이다.In order to achieve the above object, the present invention provides a fan having both ends of a rotating shaft supported on a duct and a drive gear fixed to one end of the rotating shaft, and a nozzle controlled left and right by the rotational force of the fan. And a camshaft having a driven gear and a cylindrical cam engaged with or separated from the drive gear, an operating rod freely installed on the camshaft, a driven rod installed in contact with the cylindrical cam, and a nozzle connected to the driven joint. .

이하 실시예를 도면에 의하여 설명한다.Embodiments will be described below with reference to the drawings.

본 발명은 도면에 도시한 바와 같이 팬(1)과, 캠기구(5) 및 노즐(13)로 구성되어 있다. 상기한 팬(1)은 덕트(2)에 회전축(3)의 양단이 지지되고, 회전축(3)의 일단에는 구동기어(4)가 고정되어 있다.The present invention is composed of a fan 1, a cam mechanism 5, and a nozzle 13 as shown in the figure. The fan 1 has both ends of the rotating shaft 3 supported by the duct 2, and the drive gear 4 is fixed to one end of the rotating shaft 3.

상기한 캠기구(5)는 덕트(1)의 외측에 브래킷(6)(6')을 설치하여 캠축(7)을 좌우이동할 수 있게 설치하고, 캠축(7)에 원통캠(8)을 형성함과 동시에 캠축(7)의 일단에는 상기 구동기어(4)에 치합되는 종동기어(9)가 형성되어 있으며, 상기 원통캠(8)에는 챔홈(8')을 형성하여 덕트(1)에 설치된 안내홈(10)을 따라 전후 이동되는 종동절(11)이 접촉되게 설치되어 있다. 그리고 원통캠(8)과 브래킷(6') 사이의 캠축(7)에는 코일 스프링(12)을 설치한 것이다.The cam mechanism 5 is provided with brackets 6 and 6 'outside the duct 1 so that the cam shaft 7 can be moved left and right, and a cylindrical cam 8 is formed on the cam shaft 7. At the same time, a driven gear 9 engaged with the drive gear 4 is formed at one end of the cam shaft 7, and a chamfer 8 'is formed in the cylindrical cam 8 to be installed in the duct 1. The driven joint 11 which is moved back and forth along the guide groove 10 is installed to be in contact. The coil spring 12 is installed on the camshaft 7 between the cylindrical cam 8 and the bracket 6 '.

상기한 노즐(13)은 그 외면 양측에 형성된 지지핀(14)으로 덕트(2)에 좌우 회전할 수 있게 지지함과 동시에 노즐(13)에는 노브에 의하여 좌우조절되는 윙(미도시)이 설치되어 있으며, 노즐(13)의 하단에는 지지편(15)을 형성하여 상기한 캠기구(5)의 중동절(11)에 형성된 볼(16)을 연결한 것이다. 그리고 상기한 덕트(2)의 외측에 설치된 브래킷(6'')과 크래쉬 패드(17)에 지지되고 선단에 노브(19)가 형성된 조작봉(18)을 상기한 캠축(7)에 회전이 자유롭게 연결하며, 조작봉(18)에 홈(21)을 형성하고 크래쉬 패드(17)에 지지홈(22)을 형성하여 코일 스프링(23)으로 탄설된 볼(24)을 구동기어(4)와 종동기어(9)가 치합될때 볼(24)이 홈(22)에 끼워지도록 한 스톱퍼(20)를 설치한 것이다.The nozzle 13 is supported by the support pins 14 formed on both sides of the outer surface so as to be rotated left and right on the duct 2 and at the same time, the nozzle 13 is provided with wings (not shown) which are adjusted left and right by a knob. The lower end of the nozzle 13 forms a support piece 15 to connect the ball 16 formed in the middle section 11 of the cam mechanism 5. Then, the cam shaft 7 is freely rotated on the cam shaft 7 by operating the operating rod 18 supported by the bracket 6 '' and the crash pad 17 provided on the outside of the duct 2 and the knob 19 formed at the tip. And a groove 21 formed in the operating rod 18 and a support groove 22 formed in the crash pad 17 to drive the ball 24, which is loaded with the coil spring 23, with the drive gear 4. When the gear 9 is engaged, the stopper 20 is installed so that the ball 24 fits into the groove 22.

이상과 같은 본발명은 노브(19)에 의하여 조작봉(18)을 밀어서 조작봉(18)에 형성된 홈(21)에 볼(24)을 끼우면 코일 스프링(12)은 압축되고 구동기어(4)와 종동기어(9)가 치합되므로 난방, 냉방 보턴을 조작하여 공기조화장치를 가동하면 공기조화장치의 블로워가 가동되어 덕트(1)에는 공기조화된 공기가 유동하면서 에어벤트로 토출되는 바, 이때 덕트(1)를 유동하는 공기의 풍압에 의하여 팬(1)이 회전됨에 따라 구동기어(4)가 종동기어(9)를 회전시키고 종동기어(9)의 회전에 따라 원통캠(8)이 회전하면서 종동절(11)이 캠홈(8')을 따라 좌우 이동되어 노즐(13)을 지지핀(14)을 중심으로 좌우 이동시키므로서 노즐(13)에서 분출되는 풍향이 변환되는 것이다. 상기와 같이 노즐(13)이 전후 이동되기전 또는 이동중에 노브에 의하여 윙을 좌우 회전시키면 좌우 풍향 각도도 넓게 변환시킬 수 있는 것이다.The present invention as described above is pushed the operating rod 18 by the knob 19 to insert the ball 24 in the groove 21 formed in the operating rod 18, the coil spring 12 is compressed and the drive gear (4) And driven gears (9) are meshed, so that if the air conditioner is operated by operating heating and cooling buttons, the blower of the air conditioner is operated and the air-conditioned air flows into the duct 1 and is discharged to the air vent. As the fan 1 is rotated by the wind pressure of air flowing through the duct 1, the drive gear 4 rotates the driven gear 9, and the cylindrical cam 8 rotates according to the rotation of the driven gear 9. While the driven section 11 is moved left and right along the cam groove 8 'and the nozzle 13 is moved left and right about the support pin 14, the wind direction ejected from the nozzle 13 is converted. As described above, when the wing 13 is rotated left and right by the knob before or after the nozzle 13 is moved back and forth, the left and right wind direction angles can be changed widely.

그리고 노브(19)를 잡아당겨 구동기어(4)에서 종동기어(9)를 분리시키면 캠축(7)에 설치된 코일 스프링(12)의 탄성에 의하여 종동기어(9)가 분리된 상태를 유지하고 원통캠(8)이 회전을 정지함에 따라 노즐(13)은 일정 위치에 정지되어서 에어벤트에서 토출되는 풍향은 일정위치로만 유지되는 것이다.When the driven gear 9 is separated from the drive gear 4 by pulling the knob 19, the driven gear 9 is kept separated by the elasticity of the coil spring 12 installed on the camshaft 7, and the cylinder As the cam 8 stops rotating, the nozzle 13 is stopped at a predetermined position so that the wind direction discharged from the air vent is maintained only at a predetermined position.

이상과 같이 본 발명은 덕트에 팬을 설치하여 덕트내를 유동하는 공기의 풍압에 의하여 팬을 회전시킬 때 팬의 회전에 따라 캠기구가 작동하여 노즐을 전후 이동시키므로서 노즐에서 분출되는 풍향을 자동적으로 원활하게 변환되게 하였으므로 실내의 공기조화가 균일하게 되고 탑승자의 탑승감이 양호하며, 공기조화시간이 단축되고, 캠축에 조작봉을 회전이 자유롭게 설치하여 이를 밀거나 잡아당기면 노즐의 회전 중에도 노즐의 회전 및 정지를 할 수 있으므로 그 조작이 편리한 효과 등이 있는 것이다.As described above, the present invention automatically installs a fan in the duct and rotates the fan by the wind pressure of the air flowing in the duct. Since the air conditioning in the room is uniformly converted, the passenger's comfort is good, the air conditioning time is shortened, and the operating rod is freely installed on the camshaft to push or pull it. Since it can rotate and stop, the operation is convenient.
