Abstract

PURPOSE: A wiper assembly is provided for a wiper arm to enhance rain water eliminating ability per unit-time through enabling two wiper arms furnished with each wiper blade to be widened at a specific angle relatively. CONSTITUTION: A wiper drive motor and each wiper blade(11,11') are equipped to wipe a windshield glass during rotation with driving force of the wiper drive motor. Dividable wiper arms(10,10') mounted to be widened as a specific angle and an angle adjusting unit(20) for widening dividable wiper arms are included to constitute a wiper assembly. As rain water amount that drops along a windshield glass becomes a large amount, caused by rain downpour during vehicle travel, an operational mode of wiper assembly is set as a turbo mode. Herein a turbo mode serves as a mode that maximizes rain removal amount per unit time by widening dividable wiper arms with a specific angle. In the state, via a control valve(29), hydraulic or pneumatic pressure is supplied to an actuating cylinder(21) for an actuating rod(23) to protrude outward of an actuating cylinder. Thus a divided link(25) connected to the actuating rod moves and the dividable wiper arms get widened. Additionally, when a wiper drive motor is driven, the dividable wiper arms rotate and rain water falling down along the windshield glass is eliminated.

이하, 상기한 바와 같은 본 발명에 의한 와이퍼조립체를 첨부된 도면에 도시된 실시예를 참고하여 상세히 설명하면 다음과 같다. 종래 기술의 것과 동일한 것은 동일부호를 원용하여 설명한다.Hereinafter, the wiper assembly according to the present invention as described above will be described in detail with reference to the embodiment shown in the accompanying drawings. The same as those in the prior art will be described using the same reference numerals.

도 2에 도시된 바와 같이, 본 발명에 의한 와이퍼 조립체는 크게 와이퍼구동모터(1; 도 1참고), 분리형 와이퍼암(10.10'), 각도조절부(20)를 포함한다.As shown in FIG. 2, the wiper assembly according to the present invention includes a wiper driving motor 1 (see FIG. 1), a detachable wiper arm 10.10 ′, and an angle adjusting unit 20.

상기 와이퍼구동모터(1)는 분리형 와이퍼암(10,10')의 회전을 위한 구동력을 발생시키는 부분으로 상기 와이퍼구동모터(1)에서부터 분리형 와이퍼암(10,10')까지의 동력전달 구성은 종래와 동일하므로 여기서는 설명을 생략하기로 한다.The wiper drive motor (1) is a portion for generating a driving force for the rotation of the separate wiper arms (10, 10 ') power transmission configuration from the wiper drive motor (1) to the separate wiper arms (10, 10'). Since it is the same as the conventional one, a description thereof will be omitted here.

상기 분리형 와이퍼암(10,10')은 링케이지(25)의 양단부에 구비된 연결구(4,4')에 설치되어 연동되는 연결브래키트(9)에 회전가능하게 힌지(12,12')설치되어 있다. 그리고, 각각의 분리형 와이퍼암(10,10')에는 와이퍼블레이드(11,11')가 구비되어 윈드시일드글래스를 닦아주게 된다.The detachable wiper arms 10 and 10 'are rotatably hinged to the connecting brackets 9 installed on and interlocked with the connectors 4 and 4' provided at both ends of the ring cage 25. It is installed. In addition, each of the separate wiper arms 10 and 10 'is provided with wiper blades 11 and 11' to wipe the windshield glass.

상기 분리형 와이퍼암(10,10')은 상기 힌지(12,12')를 중심으로 서로에 대해 소정 각도만큼 벌어질 수 있게 구성된다. 이를 위해 각도조절부(20)가 구비되는데, 이는 일측 분리형 와이퍼암(10,10')에 구비되는 작동실린더(21)와, 상기 분리형 와이퍼암(10,10')을 연결하는 분리링크(25)로 구성된다.The removable wiper arms 10 and 10 'are configured to be opened by a predetermined angle with respect to each other about the hinges 12 and 12'. To this end, an angle adjustment unit 20 is provided, which includes an operation cylinder 21 provided at one side wiper arm 10 and 10 'and a separation link 25 connecting the separate wiper arm 10 and 10'. It is composed of

상기 작동실린더(21)는 일측 분리형 와이퍼암(10')에 구비되고 유압이나 공압으로 작동되어 작동실린더(21) 내부에 탄지부재(24)로 탄지되어 있는 작동로드(23)를 작동시켜 상기 분리형 와이퍼암(10,10') 사이의 각도를 조절하게 된다.The actuating cylinder 21 is provided on one side of the wiper arm 10 'and is operated by hydraulic pressure or pneumatic actuation of the actuating rod 23 held by the support member 24 inside the actuating cylinder 21 to detach the actuating rod. The angle between the wiper arms 10 and 10 'is adjusted.

상기 분리링크(25)는 일측 단부가 타측 분리형 와이퍼암(10)에 힌지(25P)를 중심으로 회전가능하게 설치되고 타측 단부가 상기 작동실린더(21)의 작동로드(23)에 연결 설치되어 있다.One side end of the separation link 25 is rotatably installed around the hinge 25P on the other side detachable wiper arm 10, and the other end is connected to the operation rod 23 of the operation cylinder 21. .

도면중 미설명 부호 29는 제어밸브이다.In the figure, reference numeral 29 is a control valve.

이하, 상기한 바와 같이 구성된 본 발명에 의한 와이퍼조립체의 작용을 상세히 설명하면 다음과 같다.Hereinafter, the operation of the wiper assembly according to the present invention configured as described above in detail.

차량의 주행중에 폭우가 쏟아져 윈드시일드글래스를 타고 내리는 빗물의 양이 많아지게 되면, 와이퍼조립체의 작동모드를 터보모드(여기서, 터보모드란 상기 분리형 와이퍼암(10,10')을 소정 각도로 벌려주어 단위시간당의 빗물제거량을 최대로 해주는 모드를 말한다.)로 설정한다.When heavy rain pours out while driving the vehicle, the amount of rainwater falling on the windshield glass increases, and the operation mode of the wiper assembly is changed to the turbo mode (here, the turbo mode means the separate wiper arms 10 and 10 'at a predetermined angle. It is a mode that maximizes the amount of rainwater removal per unit time.

이와 같이 되면, 상기 제어밸브(29)를 통해 상기 작동실린더(21)로 유압이나 공압이 전달되어 상기 작동로드(23)가 작동실린더(21)의 외부로 돌출된다. 따라서 상기 작동로드(23)에 연결설치되어 있는 분리링크(25)가 이동하면서, 도 3에 도시된 바와 같이 분리형 와이퍼암(10,10')이 소정의 각도로 벌어지게 된다.In this case, hydraulic pressure or pneumatic pressure is transmitted to the operation cylinder 21 through the control valve 29, and the operation rod 23 protrudes out of the operation cylinder 21. Accordingly, as the separation link 25 connected to the operation rod 23 moves, the separation wiper arms 10 and 10 'are opened at a predetermined angle as shown in FIG. 3.

그리고는 상기 와이퍼구동모터(1)가 구동되면 상기 분리형 와이퍼암(10,10')이 회전되면서 윈드시일드글래스를 타고 내리는 빗물을 제거하여 주게 된다.Then, when the wiper drive motor 1 is driven, the separate wiper arms 10 and 10 'are rotated to remove rain water that rides down the windshield glass.

이를 도 4를 참고하여 보다 상세히 설명하면, 예를 들어 분리형 와이퍼암(10,10')이 우측에 접혀져 있는 상태(상태①)에서 터보모드가 선택되면 상기 작동실린더(21)의 작동에 의해 분리형 와이퍼암(10,10')이 소정 각도로 펼쳐지면서 작동된다.(상태②). 그리고는 분리형 와이퍼암(10,10')은 계속하여 구동되어 상태③을 거쳐 일측 분리형 와이퍼암(10,10')이 완전히 좌측으로 이동된 상태(상태④)에 이르게 되고, 이번에는 역방향으로의 회전이 수행되면서 이와 같은 동작이 반복된다.This will be described in more detail with reference to FIG. 4. For example, when the turbo mode is selected in a state in which the detachable wiper arms 10 and 10 'are folded on the right side (state ①), the detachable type is operated by the operation cylinder 21. The wiper arms 10 and 10 'are operated while being unfolded at a predetermined angle (state ②). Then, the detachable wiper arms 10 and 10 'are continuously driven to reach a state (state ④) in which the one side detachable wiper arms 10 and 10' are completely moved to the left side (state ④). This operation is repeated as the rotation is performed.

상기와 같이 분리형 와이퍼암(10,10')이 소정각도로 펼쳐진 상태에서 회전하면 복수개의 와이퍼블레이드(11,11')가 일정의 시차를 두고 계속적으로 윈드시일드글래스를 타고 흘러내리는 빗물을 제거하여 주게 된다.As described above, when the separate wiper arms 10 and 10 'are rotated at a predetermined angle, the plurality of wiper blades 11 and 11' continuously remove wind water flowing down the windshield glass with a predetermined time difference. Will be given.

위에서 상세히 설명한 바와 같은 본 발명에 의한 와이퍼조립체는 각각 블레이드를 구비한 복수개의 분리형 와이퍼암이 소정각도를 유지하면서 윈드시일드글래스상의 빗물을 제거하여 주도록 되므로 단위시간당의 빗물제거량이 향상되어 특히 폭우가 내리는 경우에 보다 효과적으로 윈드시일드글래스상의 빗물을 제거하여 시야확보를 할 수 있으며 평상시에도 분리형 와이퍼암에 각각 구비된 블레이드가 윈드시일드글래스를 이중으로 닦아주게 되므로 보다 세척효과가 뛰어나게 되는 효과가 있다.As described in detail above, the wiper assembly according to the present invention is provided with a plurality of separate wiper arms each having a blade to remove rainwater on the windshield glass while maintaining a predetermined angle, so that the rainwater removal amount per unit time is improved. When lowering, the rainwater on the windshield glass can be removed more effectively to secure the field of view, and the blades provided on the separate wiper arm can wipe the windshield glass twice, so the cleaning effect is excellent. .
