[발명의 상세한 설명]본 발명은 자동차의 워셔액 분사노즐에 관한 것으로서, 특히 자동차의 전면창 전체에 골고루 워셔액을 분사시켜주기 위해서 분사노즐을 전동장치에 의해 회전시켜주는 자동차의 워셔액 분사노즐 회전장치에 관한 것이다.Detailed Description of the Invention [0001] The present invention relates to a washer fluid jet nozzle of a motor vehicle, and more particularly, to a washer fluid jet nozzle rotating apparatus of a motor vehicle, which rotates the jet nozzle by an electric device in order to spray the washer fluid evenly over the entire front window of the motor vehicle. It is about.

본 발명은 이러한 점을 감안하여 안출한 것으로서, 프로그램에 따라 정역구동하는 구동모터로부터 동력을 전달받아서 회전하는 구동기어와, 상기 구동기어와 맞물려서 지지체에 내설되어 구동기어의 회전에 따라 전·후방으로 수평이동 하는 수랙기어와, 수랙기어의 일단에 형성된 볼조인트에 연결된 링크와, 상기 링크의 타단에 볼조인트에 의해 연결되고 링크와 편심되게 설치되어 링크의 수평동작에 따라 회동하는 회동부와, 상기회동부의 상부에 형성되며 워셔액을 분사하는 분사구가 형성된 분사노즐과, 상기 분사노즐의 외주부와 볼베어링에 의해 접촉되며, 본네트의 나사부와 외주부에 형성된 나사산이 체결되는 고정부로 구성된 워셔액 분사노즐 회전장치를 구비하여 전면창의 전부분에 워셔액을 골고루 분사시켜주는 자동차의 워셔액 분사노즐 회전장치를 제공하는데 그 목적이 있다.리고, 상기 지지체(4)(4')에는 상기 랙기어(3)의 전·후방동작을 제어하도록 전방 및 후방 스토퍼(4a)(4a')(4b)(4b')가 형성되어 있다.The present invention has been made in view of this point, and the drive gear is rotated by receiving power from the drive motor that is driven forward and backward according to the program, and the drive gear meshed with the drive gear is built in the support to the front and rear in accordance with the rotation of the drive gear A horizontally moving male gear, a link connected to a ball joint formed at one end of the male gear, a rotating part connected to the other end of the link by a ball joint and installed eccentrically with the link to rotate according to a horizontal motion of the link, and Washer liquid injection nozzle rotating device which is formed on the upper part of the rotating part and formed with a spray nozzle having a spray hole for spraying the washer fluid, and a fixed part which is contacted by the outer peripheral portion and the ball bearing of the spray nozzle, and the screw thread formed in the outer peripheral portion of the bonnet Washer liquid injection of car to spray washer liquid evenly on all parts of the front window It is an object of the present invention to provide a bladder rotating device. In addition, the support 4, 4 'includes front and rear stoppers 4a, 4a', and 4b to control the front and rear motions of the rack gear 3. ) 4b 'is formed.

그리고, 전면창(A)의 좌·우방향으로 워셔액을 분사시키고자 할때에는 측면방향에 설치된 구동무터(1')를 구동시켜서 분사노즐(7a)을 좌·우방향으로 이동시켜 워셔액을 분사시키도록 한다.In order to inject the washer fluid in the left and right directions of the front window A, the driving nozzle 1 'installed in the side direction is driven to move the injection nozzle 7a in the left and right directions to inject the washer fluid. To do that.
