Description

전자석 와이퍼Electromagnet wiper

본 발명은 우천시 운전자의 시야를 확보하기 위한 자동차용 와이퍼장치에 관한 것으로, 특히 종래의 링크식 타입이 아닌 전자석식 와이퍼에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile wiper device for securing a driver's field of vision in rainy weather, and more particularly, to an electromagnetic wiper that is not a conventional link type.

와이퍼의 구동방식은 1개의 모터로 1본의 블레이드를 움직이게 하는 단동식과 2본 또는 3본의 블레이드를 움직이게하는 연동식이 있고, 연동식의 경우 와이핑패턴에는 두 개의 불레이드가 동일방향으로 움직이는 병렬형과 서로 반대 방향으로 움직이는 오퍼지트형이 있지만 시야, 풍압저항, 구조 등의 측면에서 병렬형이 유리하기 때문에 많이 이용되고 있다.There are two types of wiper drive: single motor with one motor and interlocking type with two or three blades.In the interlocking type, two blades move in the same direction in the wiping pattern. Although there is an operative type that moves in the opposite direction from the mold, the parallel type is advantageous in view of the field of view, wind pressure resistance, and structure.

그러나 전기한 기존의 와이퍼장치는 모터와 와이퍼 사이에 링크와 피봇(PIVOT)을 설치하는 링크식이기 때문에 링크부재를 연결하는 피봇부에서 소음이 발생하고 와이핑 면적에 한계가 있었다.However, since the conventional wiper device is a link type that installs a link and a pivot (PIVOT) between the motor and the wiper, noise occurs in the pivot part connecting the link member and the wiping area is limited.

본 발명은 전기한 종래의 링크형 와이퍼장치의 문제점을 개선하기 위하여, 링크부재와 모터를 삭제하고 영구자석이 부착된 와이퍼, 차체쪽에 설치된 전자석 및 전자제어유니트(ECU)에 의해 와이퍼장치를 구성하여 종래 링크형 와이퍼의 소음을 감소 시키고, 원가를 절감하며 고장이 적고 내구력을 증대시킨 와이퍼장치를 제공함에 그 목적이 있다.The present invention, in order to improve the problems of the conventional link-type wiper device described above, by removing the link member and the motor, the wiper device is configured by a wiper attached to the permanent magnet, an electromagnet and an electronic control unit (ECU) installed on the vehicle body side. The purpose of the present invention is to provide a wiper device that reduces noise, reduces costs, and has a low failure rate and increased durability of a conventional link type wiper.

도 1 은 본 발명에 의한 전자석 와이퍼 장치의 개략도1 is a schematic view of an electromagnet wiper device according to the present invention;

이를 위해 본 발명은, 차체전면유리부상에서 와이핑작용을 하는 와이퍼암, 차체의 카울(COWL)부에 설치된 전자석 그리고 전자제어유니트로 이루어진 전자석식 와이퍼 장치를 구현하였다.To this end, the present invention implements an electromagnet wiper device consisting of a wiper arm that performs a wiping action on the vehicle front glass part, an electromagnet installed in a COWL part of the vehicle body, and an electronic control unit.

이하, 본 발명의 실시예를 첨부도면에 의해 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with the accompanying drawings.

도 1은 본 발명의 정면도이다.1 is a front view of the present invention.

도 1에 도시된 바와 같이 본 발명은 와이핑작용을 하는 와이퍼암(1)을 힌지(5)에 의해 차체의 일측에 설치하고, 와이퍼암(1)에는 영구자석(2)을 설치하며, 미도시한 차체의 카울부에는 전자석(3)을 설치하고, 전자석(3)에는 전원과 전자제어유니트(4)를 설치하여 영구자석(2)과 전자석(3)의 반발력에 의해 와이핑작용을 하도록 이루어져 있다.As shown in FIG. 1, the present invention provides a wiper arm 1 having a wiping action on one side of the vehicle body by a hinge 5, and a permanent magnet 2 is installed on the wiper arm 1. An electromagnet 3 is installed in the cowl portion of the illustrated vehicle body, and a power source and an electronic control unit 4 are installed in the electromagnet 3 so that the wiping action is performed by the repulsive force of the permanent magnet 2 and the electromagnet 3. consist of.

이와같이 이루어진 본 발명의 작용을 설명한다.The operation of the present invention thus made will be described.

와이퍼암(1)에는 영구자석(2)이 설치되어있고, 차체의 카울부에는 전자석(3)이 설치되어 있으므로 영구자석(2)과 전자석(3) 사이의 극성을 서로 다르게 하면 영구자석(2)과 전자석(3) 사이의 반발력에 의해 와이퍼암(1)은 힌지(5)를 중심으로 회전하면서 와이핑작용을 한다. 이때 와이핑면적은 반발력의 크기에 의해 결정되며 최고점에 이르른 후 와이퍼암(1)은 자중에 의해 또는 전자제어유니트(4)에 의해 전자석(3)의 극성을 영구자석(2)과 반대로 하면 흡인력에 의해 하강하게 된다. 여기서 전자제어유니트(4)는 전자석(3)의 극성을 서로 반대로 하게 하거나 자기력의 세기를 변경하고 와이핑 타임을 변경하는 작용을 한다.The wiper arm 1 is provided with a permanent magnet 2, and the cowl of the vehicle body is provided with an electromagnet 3, so if the polarities between the permanent magnet 2 and the electromagnet 3 are different from each other, the permanent magnet 2 The wiper arm 1 rotates about the hinge 5 by the repulsive force between the magnet and the electromagnet 3. At this time, the wiping area is determined by the size of the repulsive force, and after reaching the highest point, the wiper arm (1) is attracted when the polarity of the electromagnet (3) is reversed from the permanent magnet (2) by its own weight or by the electronic control unit (4). Descend by The electronic control unit 4 serves to reverse the polarity of the electromagnet 3 or to change the strength of the magnetic force and the wiping time.

이와같이 본 발명은 영구자석(2)이 부착된 와이퍼암(1)과 전자석(3)을 이용하여 와이퍼 장치를 구성하고 있으므로 종래 링크형 와이퍼 장치에서의 링크구조, 모터 등이 불필요하게 되어 링크연결부에서 발생하는 소음을 줄일 수 있고 고장이 적으며 내구력을 증대시킬 수 있다.As described above, the present invention constitutes a wiper device by using the wiper arm 1 and the electromagnet 3 to which the permanent magnet 2 is attached. Therefore, the link structure, the motor, and the like in the conventional link type wiper device become unnecessary, It can reduce the noise generated, less trouble and increase the durability.

이상과 같이 본 발명은 종래 와이퍼시스템내의 복잡한 링크류와 모터를 제거하여 영구자석과 전자석 그리고 전자제어유니트에 의한 간단한 구조로 와이퍼장치를 구성하였기 때문에 종래 링크형 와이퍼 장치의 단점인 소음을 저감할 수 있고, 간단한 구조이기 때문에 고장 위험도 적어지는 효과가 있다.As described above, the present invention can reduce the noise, which is a disadvantage of the conventional link type wiper device, because the wiper device is configured by a simple structure by permanent magnets, electromagnets, and electronic control units by removing complicated links and motors in the conventional wiper system. In addition, since the structure is simple, the risk of failure can be reduced.
