본고안은 자동차의 윈드실드에 빗물과 눈 기타 오물을 제거하여 운전자의 시야를 확보하기 위한 자동차용 와이퍼에 관한 것이다.This article relates to a windscreen wiper for the driver's vision by removing rain, snow and other debris from the windshield.

본고안에 의하면 장형의 일자 판스프링 세로 중간부에 일정한 폭의 폐쇄된 세로공간부(5)를 펀칭한 다음 만곡 성형 후 판스프링의 일단을 절단 절곡하여 개구연결부(7)를 성형하며 판스프링의 중간부분에 클립(2)을 고정한 다음 개구부(10)를 통하여 블레이드고무(14)를 삽입하고 캡(15)을 삽착하여 블레이드고무(14)가 흘러내리지 않도록 한 자동차용 와이퍼에 관한 것이다.According to the proposal, a long vertical slot spring is punched by a closed longitudinal space part 5 having a constant width in the middle of the longitudinal length, and then the end of the leaf spring is cut and bent to form an opening connecting part 7 after bending molding. After fixing the clip (2) to the portion and inserts the blade rubber 14 through the opening 10 and the cap 15 is inserted into the wiper for the vehicle so that the blade rubber 14 does not flow down.

종래의 와이퍼는 다수의 아암으로 연결된 구조로 되어있어 각 아암 힌지부의 유격으로 인하여 흔들림이 심하고 그 결과 와이퍼의 닦임 효율이 떨어지고 수명저하의 원인이 되어왔다.The conventional wiper has a structure in which a plurality of arms are connected to each other, so that the wiping of each arm hinge causes severe shaking, and as a result, the wiping efficiency of the wiper is reduced and the life is reduced.

이에 판스프링을 이용한 일체형 와이퍼가 개발되어 아암과 힌지를 없앰으로써 현저한 개선이 이루어졌다.Thus, an integrated wiper using a leaf spring has been developed, which is a significant improvement by eliminating the arm and the hinge.

그러나 기존의 판스프링을 이용한 와이퍼는 2개의 얇은 판스프링을 각각 따로 만곡 가공하고 이를 블레이드고무(14)의 상하부 지지대(11)(13) 사이 양측홈에 2~3㎜ 깊이로 전체길이에 걸쳐 일단 삽입한 다음 클립(2)의 괘지구(17)를 이용하여 판스프링과 클립(2)을 체결 고정하는 방식으로 조립하고 있다.However, the wiper using the existing leaf spring is bent two thin leaf springs separately, and this is once over the entire length to the depth of 2-3 mm in both grooves between the upper and lower supports 11, 13 of the blade rubber (14) Inserted and assembled by fastening and fixing the leaf spring and the clip (2) using the ruler 17 of the clip (2).

이는 그 조립 방식이 매우 정교하여야할 뿐 아니라 특수한 전용 조립 장비와 매우 숙련된 기능공에 의해서 조립이 가능하고 또한 조립 속도가 늦어 생산성이 매우 떨어지고 결과적으로 제조 원가가 상승하는 요인이 될 뿐 아니라 품질이 안정적 이지 못한 불리한 점들이 있어왔다.Not only is the assembly method very sophisticated, it can be assembled by special dedicated assembly equipment and highly skilled technicians, and the assembly speed is low, which leads to a very low productivity and a high cost of manufacturing. There have been disadvantages that have not been.

따라서 본고안은 상기의 문제점들을 해결하기 위한 것으로 본고안의 목적은 폐쇄된 세로공간부(5)를 펀칭한 판스프링에서 개구연결부(7)를 성형함으로써 개구부(10)가 열리고 동시에 좌우측 판스프링 단부돌기(8)(9)가 성형되어 이를 통하여 블레이드고무(14)를 삽탈할 수 있도록한다.Therefore, this paper is intended to solve the above problems. The purpose of this paper is to open the opening 10 by forming the opening connecting portion 7 in the leaf spring punching the closed longitudinal space portion 5 and at the same time the left and right leaf spring end projections. (8) and (9) are molded so that the blade rubber 14 can be inserted therethrough.

또한 좌우측 판스프링(3)(4)과 막힘연결부(6),개구연결부(7)는 절단되지 않는 연결 상태로 남아있게 됨으로써 일체형의 강성구조체로 성형되어 와이퍼 작동시 판스프링이 받게되는 회전 및 비틀림 모우멘트로 인한 변형 그리고 진동이나 흔들림으로부터 안정적인 구조체를 제공하는 것이다.In addition, the left and right leaf springs (3) (4) and the clogged connection (6), the opening connection (7) is left in a non-cut connection state is formed into an integral rigid structure to rotate and torsion to receive the leaf spring during the wiper operation It provides a stable structure against momentary deformation and vibration or shaking.

또 세로공간부(5)의 간격을 일정하게 유지시켜 품질을 안정 시키고 판스프링이 일체형으로 구성됨으로써 공수를 줄이고 조립작업시 취급성이 좋아 생산성을 높이고 불량률이 줄어든 자동차용 와이퍼를 제공하는 것이다.In addition, by maintaining a constant interval of the vertical space (5) to stabilize the quality and the plate spring is integrally configured to reduce the man-hours, good handling when assembling work to improve productivity and to provide a car wiper with a reduced defective rate.

상기 목적을 달성하기 위하여 본고안은 도 3에 도시된 바와 같이 장형의 긴 판스프링 세로 중간부에 폐쇄된 세로공간부(5)를 펀칭하고 나머지 부분인 좌우측 판스프링(3)(4)과 막힘연결부(6)와 개구연결부(7)는 연결 상태로 두어 일체형의 긴 ㅁ 자형의 판스프링으로 성형한다.In order to achieve the above object, the present invention punches the longitudinal space portion 5 closed in the longitudinal middle portion of the long elongated leaf spring as shown in FIG. 3 and clogs the left and right leaf springs 3 and 4 which are the remaining portions. The connecting portion 6 and the opening connecting portion 7 are connected to each other to be molded into an integral long K-shaped leaf spring.

이후 이를 도 4와 같이 만곡형으로 곡면 가공하되 일측 끝단을 점선대로 절단 절곡하면 도 5와 같이 성형된다.Thereafter, this is curved as shown in FIG. 4, but when one end is cut and bent as a dotted line, it is molded as shown in FIG. 5.

도 4에서 점선은 개구연결부(7)를 성형하는 선으로써 이 점선은 세로 공간부(5)의 일측 끝단과 접해있고 또한 좌우측 판스프링(3)(4)의 중간을 따라 세로공간부(5) 쪽으로 일정한 길이를 유지하고 있으며 횡방향으로 접음선(18)이 있다.In FIG. 4, the dotted line is a line forming the opening connecting portion 7, which is in contact with one end of the vertical space portion 5, and also along the middle of the left and right leaf springs 3, 4. It has a constant length toward the side and there is a fold line 18 in the transverse direction.

이들 점선을 따라 절곡과 절단을 하게 되면 [제 6도의 개구연결부(7)부분 확대 사시도 참고] 개구연결부(7)가 일정한 각도로 들어져서 좌우측 판스프링(3)(4)과 일정한 간격을 유지하며 평행 상태가 되고 동시에 개구부(10)가 열리게 되며 좌우측 판스프링 단부돌기(8)(9)가 성형되게 된다.When bending and cutting along these dashed lines [refer to the enlarged perspective view of the opening connecting portion 7 of FIG. 6], the opening connecting portion 7 is lifted at an angle to maintain a constant distance from the left and right leaf springs 3 and 4, respectively. At the same time, the opening 10 is opened and the left and right leaf spring end protrusions 8 and 9 are molded.

물론 이때 개구연결부(7)는 절단되지 않고 단순히 절곡되어 좌우측 판스프링(3)(4)과 일체로 연결되어있다.Of course, at this time, the opening connecting portion 7 is simply not bent and is integrally connected with the left and right leaf springs 3 and 4.

이상태가 도5의 상태이며 판스프링은 여전히 하나의 일체형 판스프링이다.This is the state of FIG. 5 and the leaf spring is still one integral leaf spring.

이상과 같이 성형된 판스프링의 중간 부분에 와이퍼아암(1)의 끝부 U형훅과 결합되는 연결체를 내삽한 클립(2)을 클립(2)양 끝에 성형한 괘지구(17)를 이용하여 고정하면 도 2에서 블레이드고무(14)를 제외한 도면 상태가 된다.The clip (2) interpolating the coupling body engaged with the U-shaped hook at the end of the wiper arm (1) is fixed to the middle of the leaf spring formed as described above using the ruler (17) formed at both ends of the clip (2). 2 is a drawing state excluding the blade rubber 14 in FIG.

이렇게 결합된 상태에서 블레이드고무(14)를 삽입하는데 도 2에서와 같이 개구부(10)를 통하여 삽입하되 목(12)이 세로공간부(5)에 끼워지도록 하여 삽입하면 좌우측 판스프링단부돌기(8)(9)는 각각 상부지지대(11)와 하부지지대(13)사이 각각의 홈에 삽입 된다.In this state, the blade rubber 14 is inserted, but is inserted through the opening 10 as shown in FIG. 2, but when the neck 12 is inserted into the vertical space 5, the left and right leaf spring end projections 8 are inserted. 9 is inserted into each groove between the upper support 11 and the lower support 13, respectively.

물론 이때 개구연결부(17)는 절곡되어 좌우측 판스프링 단부돌기(8)(9)와 일정한 간격을 유지하며 들려있으므로 그 간격 사이로 상부지지대(11)가 통과 가능하다.Of course, at this time, the opening connection part 17 is bent and held at a constant distance from the left and right leaf spring end protrusions 8 and 9 so that the upper support 11 can pass through the gaps.

이렇게 개구부(10)를 통하여 삽입된 블레이드고무(14)를 계속 밀어넣으면 상부지지대(11)가 클립(2)의 아래를 지나 막힘 연결부(6)에 닿아 정지하게 된다.When the blade rubber 14 inserted through the opening 10 is continuously pushed in, the upper support 11 passes through the bottom of the clip 2 and comes into contact with the plugged connection 6 to stop.

이어서 좌우측 판스프링 단부돌기(8)(9)가 캡홈(16)에 삽입되도록 하여 캡(15)을 삽입하면 블레이드고무(14)는 판스프링에 완전히 고정된다.Subsequently, the left and right leaf spring end protrusions 8 and 9 are inserted into the cap groove 16 so that the blade rubber 14 is completely fixed to the leaf spring.

결과적으로 블레이드고무(14)는 상하부지지대(11)(13)와 목(12) 그리고 좌우측 판스프링(3)(4)과 막힘연결부(6)와 캡(15)에 의해 일체로 결합된다.As a result, the blade rubber 14 is integrally coupled by the upper and lower support members 11 and 13 and the neck 12 and the left and right leaf springs 3 and 4, the clogging connection 6 and the cap 15.

개구연결부(7) 부분의 또 다른 일실시 예로써 폐쇄된 세로공간부(5)를 펀칭한 판스프링에서 개구연결부(7)를 성형함으로써 개구부(10)가 열리고 동시에 좌우측 도입단부(19)(20)가 성형되고 이 좌우측 도입단부(19)(20)를 통하여 블레이드고무(14)가 삽탈될 수 있는 입구가 되도록한다.As another embodiment of the portion of the opening connecting portion 7, the opening 10 is opened by forming the opening connecting portion 7 in the leaf spring punching the closed longitudinal space portion 5, and at the same time the left and right leading ends 19 and 20 are formed. ) Is shaped so that the blade rubber 14 can be inserted through the left and right introduction ends 19 and 20.

또한 좌우측 판스프링(3)(4)과 막힘연결부(6),개구연결부(7)는 역시 절단되지 않는 연결 상태로 남아있게 됨으로써 일체형의 강성구조체를 유지하게된다.In addition, the left and right leaf springs (3) (4) and the clogged connection portion 6, the opening connection portion 7 is also left in a non-cut connection state to maintain the integral rigid structure.

도 1은 본고안에 의한 자동차용 와이퍼의 확대 정면도이며 도 2는 본 고안에 의한 자동차용 와이퍼의 요부 분리사시도이다.1 is an enlarged front view of an automobile wiper according to the present invention, and FIG. 2 is an exploded perspective view of main parts of an automobile wiper according to the present invention.

도 3은 본고안 장형 판스프링에 세로공간부를 펀칭한 상태의 사시도이며 도 4는 본고안 도 3의 상태에서 판스프링을 만곡 성형한 상태의 사시도이다.3 is a perspective view of a state in which the longitudinal space portion is punched into the long leaf spring of the present invention, and FIG. 4 is a perspective view of a state of bending the leaf spring in the state of FIG.

도 5는 본고안 도 4의 상태에서 개구연결부를 성형한 상태의 사시도이며 도 6은 본고안에 의한 개구연결부 부분의 확대 분리 사시도이고, 도 7은 본고안에 의한 개구연결부 부분의 또 다른 실시예를 보인 사시도이다.FIG. 5 is a perspective view of the opening connecting portion formed in the state of FIG. 4 and FIG. 6 is an enlarged and separated perspective view of the opening connecting portion according to the present invention, and FIG. 7 shows another embodiment of the opening connecting portion according to the present invention. Perspective view.

또한 마모된 블레이드고무(14)는 캡(15)을 빼고 새 것으로 교체 한뒤 다시 캡(15)을 끼움으로써 간단히 교체할 수도 있다.Worn blade rubber 14 may also be replaced simply by removing the cap 15, replacing it with a new one, and then inserting the cap 15 again.

이상의 와이퍼 블레이드 구성체를 기존의 와이퍼아암 끝단부 U형훅과 탈착하는 방법은 기존 와이퍼블레이드와 동일하다.The wiper blade structure is detachable from the existing wiper arm end U-shaped hook in the same manner as the conventional wiper blade.

이상과 같은 본 고안에서 좌우 판스프링(3)(4)과 막힘연결부(6) 그리고 개구연결부(7)가 절단됨 없이 일체형으로 연결되어 있어서 그 구조가 매우 강성구조이다.In the present invention as described above, the left and right leaf springs (3) (4) and the clogged connecting portion 6 and the opening connecting portion (7) is connected integrally without cutting the structure is a very rigid structure.

더욱이 두 판스프링(3)(4) 사이는 블레이드고무(14)를 삽입하기 위해서 세로공간부(5)를 성형한 상태인 관계로 구조적으로 약할 수 밖에 없는데 이를 보완하기 위한 구조로써 판스프링은 일체형의 안정된 구조로 구성하였다.Moreover, between the two leaf springs (3) and (4) in the state of forming the longitudinal space portion (5) for inserting the blade rubber (14) is structurally weak, but as a structure to compensate for this, the leaf spring is integral It was composed of a stable structure.

그 결과 와이퍼아암(1)의 회전 모우멘트가 클립(2)을 거쳐 얇고 긴 좌우 판스프링(3)(4)으로 전달될 때 두 판스프링(3)(4)의 변형이나 흔들림, 작동시 떨림을 효과적으로 막을 수 있다.As a result, when the rotation moment of the wiper arm 1 is transferred to the thin and long left and right leaf springs 3 and 4 via the clip 2, the deformation or shaking of the two leaf springs 3 and 4, and the vibration during operation Can be effectively prevented.

따라서 와이핑 시에 블레이드고무(14)가 드르륵 드르륵 떨리는 소리가 나거나 윈드실드를 잘게 썰어 놓은 듯한 현상이 나타나는 등의 부적합요인들이 제거되고 블레이드고무(14)의 수명을 향상 시킬 수 있다.Therefore, the unsuitable factors such as the blade rubber 14 can be shaken or the windshield shredded during wiping can be eliminated and the life of the blade rubber 14 can be improved.

무엇보다도 와이핑 시에 좌우판스프링(3)(4)의 변형이나 흔들림이 없다는 것은 와이핑 효율이 매우 높아져서 깨끗이 닦인다는 효과가 있다.Above all, the absence of deformation or shaking of the left and right leaf springs (3) and (4) at the time of wiping has an effect that the wiping efficiency is very high and cleaned.

와이퍼 블레이드의 프레임이 되는 좌우 판스프링(3)(4)은 얇고 긴 그러면서 세로공간부(5)가 성형된 약한 구조체 인데다가 여기에 결합된 블레이드고무(14)는 윈드실드와 선접촉을하고 더욱이 블레이드고무(14)의 날부분은 와이핑시에 좌우로 15°씩 움직이므로 와이퍼 블레이드의 중심이 계속 흔들리는 불안한 구조로 되어있다.The left and right leaf springs (3) and (4), which are the frames of the wiper blades, are thin and long and have a weak structure in which the vertical space portion 5 is formed, and the blade rubbers 14 coupled thereto are in line contact with the windshield. The blade portion of the blade rubber 14 has an unstable structure in which the center of the wiper blade continuously shakes because the blade portion moves 15 ° from side to side at the time of wiping.

또한 와이퍼 아암(1)에 내장된 인장 스프링에 의해서 와이퍼블레이드 자체가 윈드실드를 누르게 되어있다.In addition, the wiper blade itself presses the windshield by the tension spring built into the wiper arm (1).

즉 와이퍼가 작동될시는 클립(2)으로 집중되어 전달되는 누르는 압력과 회전 모우멘트를 동시에 받으면서 블레이드고무(14)의 날과 윈드실드 사이의 저항에 의한 마찰력과 그로인한 비틀림 모우멘트를 이겨내면서 회전해야 하는 극도의 악조건하에있다.In other words, when the wiper is operated, it receives the pressing pressure and rotation moment concentrated concentrated on the clip (2) while overcoming the frictional force caused by the resistance between the blade of the rubber blade 14 and the windshield and the torsional moment caused by the windshield. Under extreme conditions that need to rotate.

본고안 일체형 강성구조는 이러한 극도의 악조건 하에서 회전 및 비틀림 변형으로부터 매우 안정적이다.The integrated rigid structure of this invention is very stable from rotational and torsional deformation under such extreme adverse conditions.

다음으로 본 고안 효과로써 기존의 방식에서는 좌우측 판스프링(3)(4)이 따로 분리되어있어 조립이 매우 어렵다.Next, according to the present design effect, the left and right leaf springs (3) and (4) are separated separately in the existing method, which is very difficult to assemble.

그러나 본 고안에서는 도 5에 도시된 바와 같이 판스프링이 일체형으로 되어있어 취급이 매우 쉽다.In the present invention, however, the leaf spring is integrated as shown in FIG.

따라서 개구부(10)를 통하여 단순히 블레이드고무(14)를 삽입하기만 하면 된다.Therefore, it is only necessary to insert the blade rubber 14 through the opening 10.

또한 세로공간부(5) 간격이 항상 일정하여 와이퍼의 품질이 안정 된다.In addition, the space of the longitudinal space (5) is always constant, the quality of the wiper is stable.

클립(2)을 고정함에 있어서도 좌우측 판스프링(3)(4) 폭이 항상 일정하여 클립(2)의 위치만 정하여 괘지구(17)를 클립핑 하기만 하면 된다.In fixing the clip 2, the width of the left and right leaf springs 3 and 4 is always constant so that only the clip 2 is clipped by determining the position of the clip 2.

따라서 일체형으로 인해 작업 공수가 매우 줄어들고 취급이 쉽고 간단하며 품질을 일정하게 관리할 수 있어서 제조 원가, 생산성, 품질면에서 매우 효과적이다.Therefore, due to the one-piece, the work maneuver is greatly reduced, easy to handle and simple, and the quality can be managed constantly, which is very effective in terms of manufacturing cost, productivity and quality.

또한 수명을 다한 블레이드고무(14)는 캡(15) 을 빼고 블레이드고무(14)를 교체한 후 캡(15)을 재삽입하면 간단히 교체 가능한 매우 경제적인 자동차용 와이퍼블레이드를 제공 할 수 있다.In addition, the blade rubber 14, which has reached the end of its life, may be provided with a very economical wiper blade that can be easily replaced by removing the cap 15 and replacing the blade rubber 14 and then reinserting the cap 15.
