본 발명은 랙 피니언식 와이퍼 구동기구에 관한 것으로, 작동이 간편한 와이퍼 구동기구에 대한 것이다.The present invention relates to a rack pinion wiper drive mechanism, and to a wiper drive mechanism that is easy to operate.
일반적으로 자동차의 전면유리를 닦기위한 와이퍼기구는 운전자가 보다 양호한 전방시계를 확보할 수 있도록 눈이나 비가 내릴때만 아니라 전면유리에 먼지, 기름 등의 오염물질이 묻었을 때 와셔액을 분사하여 전면유리를 세척하기 위해서도 사용되고 있다.In general, the wiper mechanism for wiping the windshield of a car cleans the windshield by spraying washer fluid when the windshield is dirty or polluted, as well as when it snows or rains, so that the driver can obtain a better front vision. It is also used to.
그러나 종래기술에 있어서는 이러한 와이퍼기구가 와이퍼 모터에 의해 발생된 구동력을 링크를 통해 와이퍼암에 전달하는 방식의 구성을 취하였기 때문에 구성이 복잡한 등의 문제가 있었다.However, in the prior art, since such a wiper mechanism has a configuration in which a driving force generated by the wiper motor is transmitted to the wiper arm through a link, the configuration is complicated.
따라서, 본 발명에서는 이러한 문제점에 착안하여 구성이 간단하고 링크가 불필요한 와이퍼구동기구를 착안하기에 이르렀다.Accordingly, in the present invention, the above-mentioned problems have led to the concept of a wiper driving mechanism having a simple configuration and unnecessary a link.
이러한 종래기술의 와이퍼구동기구를 개선한 본 발명은 랙피니언식 와이퍼 구동기구를 제공하는 것을 목적으로 한다.An object of the present invention is to provide a rack pinion type wiper drive mechanism to improve the conventional wiper drive mechanism.
또한, 본 발명은 구성이 간단하고 작동효율이 양호한 와이퍼구동기구를 제공하는 것을 목적으로 한다.Moreover, an object of this invention is to provide the wiper drive mechanism which is simple in structure and good in operating efficiency.
이러한 본 발명의 목적을 달성하기 위한 랙 피니언식 와이퍼 구동기구는, 구동축을 가지는 와이퍼 모터에 의해 작동되며 원주 둘레의 대략 반에만 형성된 기어를 가지는 하부피니언기어와, 이 피니언기어에 의해 일방향으로 운동할 수 있으며, 하부 피니언기어의 기어가 형성되지 않은 부분과 접할때는 타방향으로 복귀 운동하고 와이퍼암을 회전운동시키기 위한 상부피니언기어와 맞물리는 랙 와이퍼암을 작동시키기위해 전 원주둘레에 기어가 형성된 상부피니언기어 및 랙이 하부피니언기어의 기어가 형성되지 않은 부분과 접할때 랙을 타방향으로 이동시키는 스프링을 구비한 구성으로 이루어지고 있다.The rack pinion wiper drive mechanism for achieving the object of the present invention is a lower pinion gear which is operated by a wiper motor having a drive shaft and has a gear formed only about half of the circumference, and can move in one direction by the pinion gear. When the upper pinion gear is in contact with the unformed part of the lower pinion gear, the upper gear is formed around the entire circumference to operate the rack wiper arm which engages with the upper pinion gear to return to the other direction and rotate the wiper arm. When the pinion gear and the rack are in contact with a portion where the gear of the lower pinion gear is not formed, the rack is configured to have a spring for moving the rack in the other direction.
이러한 랙 피니언식 와이퍼구동기구에 의하면 와이퍼 구동기구의 구성부품이 감소되고 단순한 구성에 의해 작동되므로 구조가 개선된 와이퍼 구동기구가 제공된다.Such a rack pinion wiper drive mechanism provides a wiper drive mechanism with an improved structure since the components of the wiper drive mechanism are reduced and operated by a simple configuration.
이하에서는 본 발명의 양호한 실시예를 도시한 첨부도면과 관련하여 본 발명이 더욱 상세하게 설명된다.The invention is explained in more detail below in connection with the accompanying drawings which show preferred embodiments of the invention.
제1도는 본 발명의 랙 피니언식 와이퍼 구동기구를 개략적으로 도시한 도면으로, 여기에서 도면부호(1)은 랙이 장착되는 본체이며, (2)는 와이퍼구동기구를 구동시키기 위한 구동모터이며, (3)은 구동모터에 의해 발행한 구동력을 하부피니언기어에 전달하는 구동축이다.1 is a view schematically showing a rack pinion wiper drive mechanism of the present invention, wherein reference numeral 1 is a main body on which a rack is mounted, and 2 is a drive motor for driving a wiper drive mechanism. (3) is a drive shaft which transmits the driving force issued by the drive motor to the lower pinion gear.
이 구동축(3)의 단부는 원주방향의 대략 반에만 기어가 형성된 하부피니언기어(4)와 결합되며, 이 하부 피니언기어(4)는 하면 및 상면에 각각 톱니 성형된 랙(5)과 결합한다. 랙(5)의 일단부는 스프링(8)을 통해 본체(1)에 연결되며, 이 스프링(8)은 랙의 하부가 하부피니언기어(4)의 기어가 형성되지 않은 부분에 접할 때 랙(5)을 본체(1)방향으로 복귀시킨다. 랙(5)의 상면에 형성된 톱니와 결합하여 와이퍼암(7)을 작동시키는 상부피니언기어(6)가 또한 구비되는데, 이 상부 피니언기어(6)는 전원주 둘레에 기어가 형성되고 있다.The end of the drive shaft 3 is engaged with the lower pinion gear 4 in which gears are formed only in about half of the circumferential direction, and the lower pinion gear 4 is engaged with the rack 5 toothed on the lower surface and the upper surface, respectively. . One end of the rack 5 is connected to the main body 1 via a spring 8, which is the rack 5 when the lower part of the rack is in contact with the unformed portion of the lower pinion gear 4. ) Is returned to the main body 1 direction. Also provided is an upper pinion gear 6 which engages the teeth formed on the upper surface of the rack 5 to actuate the wiper arm 7, which gears are formed around the mains.
제1도(a)에 도시한 바와같이 모터(2)의 구동력이 구동축(3)을 통해 하부 피니언기어(4)에 전달되어 하부 피니언기어(4)가 회전하여 기어가 형성된 부분이 랙(5)의 하부에 형성된 톱니와 맞물력서 랙(5)을 이동시키게 된다. 이때 하부 피니언기어(4)가 반시계 방향으로 회전하면 이 피니언기어(4)와 맞물린 랙(5)이 화살표(A)로 표시한 바와같이 좌측으로 운동하며, 이 좌측으로 운동하는 랙(5)의 상부에 형성된 톱니와 맞물린 전원주 둘레에 기어가 형성된 상부피니언기어(6)가 시계방향으로 회전하게 되며, 이에 따라 와이퍼암(7)은 도시와 같이 작동된다.As shown in FIG. 1A, the driving force of the motor 2 is transmitted to the lower pinion gear 4 through the drive shaft 3 so that the lower pinion gear 4 rotates to form a gear 5. The rack 5 is engaged with the teeth formed in the lower portion of the). At this time, when the lower pinion gear 4 rotates counterclockwise, the rack 5 engaged with the pinion gear 4 moves to the left as indicated by the arrow A, and the rack 5 to the left moves. The upper pinion gear 6 in which the gear is formed around the main power line engaged with the teeth formed at the top of the is rotated in the clockwise direction, and thus the wiper arm 7 is operated as shown.
제1도(b)에는 와이퍼암(7)이 (a)와는 역의 방향으로 작동하는 것을 도시하고 있는데, 여기에서는 와이퍼 구동모터(2)로 부터의 구동력에 의해 회전되는 하부피니언기어(4)가 회전하여 기어가 형성되지 않은 부분이 랙(5)의 하부와 접하게 되면 하부피니언기어(4)는 랙(5)을 운동시키지 못하므로 랙(5)은 스프링(8)의 복원력에 의해 화살표(B)로 표시한 바와같이 우측으로 운동한다. 스프링(8)의 복원력에 의해 랙(5)이 화살표(B) 방향으로 운동하면 랙(5)의 상면에 형성된 톱니와 맞물린 상부피니언 기어(6)는 반시계 방향으로 회전하게 되어 와이퍼암(7)을 도시와 같이 작동시키는 것이다.FIG. 1 (b) shows that the wiper arm 7 operates in the reverse direction to (a), where the lower pinion gear 4 is rotated by the driving force from the wiper drive motor 2. When the gear is not formed in contact with the lower part of the rack 5, the lower pinion gear 4 does not move the rack 5, so the rack 5 has an arrow ( Move to the right as indicated by B). When the rack 5 moves in the direction of the arrow B due to the restoring force of the spring 8, the upper pinion gear 6 engaged with the teeth formed on the upper surface of the rack 5 rotates counterclockwise, thereby wiper arm 7 ) Works like a city.
이러한 본 발명의 랙 피니언식 와이퍼 구동기구에 의하면 링크가 필요없는 신규한 구성의 와이퍼구동기구가 얻어지는 효과가 발생되며, 이러한 랙 피니언식 와이퍼 구동기구가 경제적임을 당업자라면 용이하게 이해할 것이다.The rack pinion wiper drive mechanism of the present invention has the effect of obtaining a wiper drive mechanism of a novel configuration that does not require a link, and those skilled in the art will readily understand that such a rack pinion wiper drive mechanism is economical.
