레인센서는 빗물감지기 또는 빗물감지센서라고도 하며, 운전자가 운전 도중에 와이퍼의 움직임이나 속도를 조절하기 위해서 별도의 움직임을 취하는 경우, 시선을 돌리거나 불필요한 동작을 함으로 인해서 발생하는 사고 또는 운전상의 불편함을 줄이기 위해 개발되었다.The rain sensor is also called a rain sensor or rain sensor, and when the driver takes a separate movement to control the movement or speed of the wiper while driving, he or she turns his gaze or makes unnecessary movements. developed to reduce

즉, 빗물이 자동차의 윈드실드 글라스에 떨어지면 윈드실드 글라스 뒷면에 설치된 레인센서가 적외선을 통해 빗물의 양과 속도를 감지하고, 감지된 빗물의 양과 속도에 따라 와이퍼 속도를 빠르게 또는 느리게 동작하도록 제어하는 방식으로 구현된다.That is, when rainwater falls on the windshield glass of the car, the rain sensor installed on the back side of the windshield glass detects the amount and speed of rainwater through infrared rays, and controls the wiper speed to operate faster or slower according to the detected amount and speed of rainwater. is implemented as

최근에는, 윈드실드 글라스에 떨어지는 빗물의 양과 속도를 측정하고자 하는 레인센서의 경우, 하나의 발광부 및 수광부를 포함하여 감지면적이 한정되고 정확한 빗물의 양과 속도 측정이 어려움이 존재하였는바, 정확한 측정을 수행하기 위한 감지면적 증대가 요구되고 있다.Recently, in the case of a rain sensor to measure the amount and speed of rainwater falling on the windshield glass, the detection area including one light emitting part and the light receiving part is limited, and it is difficult to accurately measure the amount and speed of rainwater. There is a need to increase the sensing area to perform this.

For convenience, it is assumed that the cover 114 is attached and fixed to the windshield 10 by an adhesive or a clamp.

한편, 지지블록(120)은 바디(110)에서 측 방향으로 연장 형성된다.On the other hand, the support block 120 is formed to extend in the lateral direction from the body (110).

특히, 연성인쇄회로기판(FPCB,122)은 축 방향을 따라 일측이 회로보드(112)에 전기적으로 연결되고, 그리고, 연성인쇄회로기판(122)은 축 방향을 따라 타측이 지지블록(120)에 고정된다. In particular, one side of the flexible printed circuit board (FPCB, 122) is electrically connected to the circuit board 112 along the axial direction, and the flexible printed circuit board 122 has the other side of the support block 120 along the axial direction. is fixed on

The humidity sensing module 124 is in contact with the windshield 10 and serves to detect moisture or moisture adhered to the windshield 10 .

이때, 지지블록(120)은 연성인쇄회로기판(122)을 지지함으로써 습도감지모듈(124)이 윈드쉴드(10)에 접촉되도록 하거나, 습도감지모듈(124)이 윈드쉴드(10)에 근접되도록 하는 역할을 한다.At this time, the support block 120 supports the flexible printed circuit board 122 so that the humidity sensing module 124 is in contact with the windshield 10 or the humidity sensing module 124 is close to the windshield 10 . plays a role

고정부(130)는 연성인쇄회로기판(122)을 지지블록(120)에 고정하는 역할을 한다.The fixing part 130 serves to fix the flexible printed circuit board 122 to the support block 120 .

Thus, the flexible printed circuit board 122 is bent along the trajectory of the upper surface and the circumferential surface of the support block 120 while one side is electrically connected to the circuit board 112 and is accommodated in the recessed groove 131 .

이때, 습도감지모듈(124)은 윈드쉴드(10)를 향하는 지지블록(120)의 상측면에 위치하고, 연성인쇄회로기판(122)의 상측면 또는 하측면에 실장된다.At this time, the humidity sensing module 124 is located on the upper surface of the support block 120 facing the windshield 10 , and is mounted on the upper or lower surface of the flexible printed circuit board 122 .

슬라이드블록(132)은 함몰홈부(131)에 슬라이드 끼움되어 연성인쇄회로기판(122)을 함몰홈부(131)의 내측면에 밀착시키는 역할을 한다.The slide block 132 is slide-fitted into the recessed groove 131 to bring the flexible printed circuit board 122 into close contact with the inner surface of the recessed groove 131 .

특히, 슬라이드블록(132)이 함몰홈부(131)에서 임의적으로 이탈되는 것을 방지하기 위해, 슬라이드블록(132)은 양측면에 끼움돌기(136)를 돌출 형성하고, 지지블록(120)은 끼움돌기(136)를 수용하도록 끼움홀(126)을 통공한다.In particular, in order to prevent the slide block 132 from being arbitrarily separated from the recessed groove portion 131, the slide block 132 has fitting protrusions 136 protruding from both sides thereof, and the support block 120 has fitting protrusions ( Through the fitting hole 126 to accommodate the 136).

그래서, 슬라이드블록(132)의 전측이 연성인쇄회로기판(122)을 함몰홈부(131)의 내측면으로 가압시, 끼움돌기(136)는 끼움홀(126)에 끼움된다.Thus, when the front side of the slide block 132 presses the flexible printed circuit board 122 to the inner surface of the recessed groove 131 , the fitting projection 136 is fitted into the fitting hole 126 .

물론, 끼움돌기(136)는 형상, 크기 및 개수에 한정하지 않는다.Of course, the fitting projection 136 is not limited to the shape, size, and number.

고정홈(133)은 함몰홈부(131)의 내측면에 해당되는 지지블록(120)에 형성된다. 이때, 함몰홈부(131)의 내측면은 함몰홈부(131)의 내측에서 연성인쇄회로기판(122)이 면접되는 부위에 해당된다.The fixing groove 133 is formed in the support block 120 corresponding to the inner surface of the recessed groove portion 131 . At this time, the inner surface of the recessed groove portion 131 corresponds to a portion where the flexible printed circuit board 122 is interviewed inside the recessed groove portion 131 .

그리고, 관통홀(134)은 연성인쇄회로기판(122)의 타측에 통공 형성된다.In addition, the through hole 134 is formed through the other side of the flexible printed circuit board 122 .

아울러, 걸림돌기(135)는 슬라이드블록(132)의 전측에 돌출되어, 관통홀(134)과 고정홈(133)에 삽입됨으로써, 연성인쇄회로기판(122)이 함몰홈부(131)에서 이탈되는 것을 방지하는 역할을 한다. 물론, 걸림돌기(135)는 다양한 형상으로 변형 가능하다.In addition, the locking projection 135 protrudes from the front side of the slide block 132 and is inserted into the through hole 134 and the fixing groove 133 , so that the flexible printed circuit board 122 is separated from the recessed groove 131 . serves to prevent Of course, the locking projection 135 is deformable in various shapes.

결과적으로, 슬라이드블록(132)이 지지블록(120)에 결속됨과 연동되어 연성인쇄회로기판(122)을 함몰홈부(131)의 내측에 견고하게 고정한다.As a result, the slide block 132 is coupled to the support block 120 and is interlocked to firmly fix the flexible printed circuit board 122 to the inside of the recessed groove 131 .

또한, 지지블록(120)은, 습도감지모듈(124)이 윈드쉴드(10)에 밀착되거나 최대한 근접되도록, 연성인쇄회로기판(122)을 탄성 지지하는 코일스프링(140)을 구비한다. In addition, the support block 120 includes a coil spring 140 for elastically supporting the flexible printed circuit board 122 so that the humidity sensing module 124 is closely attached to or as close to the windshield 10 as possible.

특히, 코일스프링(140)이 연성인쇄회로기판(122)과 선접촉을 함에 따라, 연성인쇄회로기판(122)과의 접촉 면적이 기존 대비 저하되어 통기성이 향상된다.In particular, as the coil spring 140 is in line contact with the flexible printed circuit board 122 , the contact area with the flexible printed circuit board 122 is reduced compared to the conventional one, thereby improving air permeability.

아울러, 코일스프링(140)은 세라믹 재질 등 절연 재질로 제작됨으로써 금속 재질로 제작됨에 따른 습도감지모듈(124)의 오작동을 방지할 수 있다.In addition, since the coil spring 140 is made of an insulating material such as a ceramic material, it is possible to prevent a malfunction of the humidity sensing module 124 due to being made of a metal material.

지지블록(120)은 코일스프링(140)을 정위치 설정하기 위해 위치설정돌기(142)를 돌출 형성한다. 코일스프링(140)의 하측을 위치설정돌기(142)에 축 삽입함으로써, 위치설정돌기(142)는 정위치 고정된다. 물론, 위치설정돌기(142)는 다양한 형상으로 변형 가능하다.The support block 120 protrudes the positioning protrusion 142 to set the coil spring 140 in its original position. By inserting the lower side of the coil spring 140 into the positioning protrusion 142, the positioning protrusion 142 is fixed in place. Of course, the positioning protrusion 142 can be deformed into various shapes.
