본 고안은 와이퍼모터용 워엄기어와 릴레이플레이트의 조립구조에 관한 것으로, 특히 스프링에 의해 돌출된 접점이 접촉되어 워엄기어의 상부에 조립된 릴레이플레이트위를 회전할 때 소리가 나거나 걸리는 것을 방지하도록 한 와이퍼모터용 워엄기어와 릴레이플레이트의 조립구조에 관한 것이다.The present invention relates to the assembly structure of the worm gear and the relay plate for the wiper motor, in particular to prevent the sound or jam when the contacts protruding by the spring to contact the rotary plate assembled on the upper part of the worm gear. The present invention relates to an assembly structure of a worm gear for a wiper motor and a relay plate.

일반적으로 와이퍼모터의 워엄기어에 릴레이플레이트를 적용하는 것은 워엄기어가 사출물로 제조되어 접단속을 위해 사용하게 된다.In general, the application of the relay plate to the worm gear of the wiper motor is that the worm gear is manufactured as an injection molding and used for contact control.

이러한 종래 와이퍼모터용 워엄기어와 릴레이플레이트의 조립구조는 도 5에 도시된 것과 같이, 외주면에 기어를 갖춘 워엄기어(10)의 측면에 소정형상의 플레이트설치홈(11)이 형성되는 한편, 이 플레이트설치홈(11)에 대응하는 도체인 릴레이플레이트(20)가 끼워져 있다.The assembly structure of the worm gear and the relay plate for the conventional wiper motor is, as shown in Figure 5, the plate mounting groove 11 of a predetermined shape is formed on the side of the worm gear 10 having a gear on the outer peripheral surface, The relay plate 20 corresponding to the plate mounting groove 11 is fitted.

좀더 상세히 설명하면, 상기 워엄기어(10)의 플레이트설치홈(11)에는 소정형상으로 꺽인 밀착부(11a,11b)가 형성되어 있는 한편, 상기 플레이트설치홈(11)의 소정위치에는 릴레이플레이트(20)의 후술하는 돌출핀이 삽입되는 구멍(12)이 형성되어 있다.In more detail, the plate mounting groove 11 of the worm gear 10 is formed in the contact portion (11a, 11b) bent in a predetermined shape, while the relay plate ( The hole 12 into which the below-mentioned protruding pin of 20) is inserted is formed.

또한 상기 릴레이플레이트(20)는, 소정형상으로 프레스성형된 판형상의 플레이트부(21)와, 이 플레이트부(21)의 하부로 돌출성형된 돌출핀(22)을 갖추고 있다.In addition, the relay plate 20 includes a plate-shaped plate portion 21 press-molded in a predetermined shape, and a protruding pin 22 protruded into the lower portion of the plate portion 21.

여기서 상기 플레이트부(21)에는 상기 플레이트설치홈(11)의 밀착부(11a,11b)와 대응하는 밀착돌출부(21a,21b)가 구비되어 있다.Here, the plate portion 21 is provided with a close contact portion (21a, 21b) corresponding to the close contact portion (11a, 11b) of the plate mounting groove (11).

따라서 상기 플레이트설치홈(11)에 릴레이플레이트(20)가 설치됨으로써 접점이 릴레이플레이트(20)에 접촉될 때에는 전원이 연결되어 와이퍼모터의 작동이 이루어지고, 워엄기어(10)에 접촉될 때에는 단속되어 와이퍼모터의 작동이 이루어지지 않게 된다.Therefore, when the relay plate 20 is installed in the plate installation groove 11, when the contact is in contact with the relay plate 20, the power is connected to operate the wiper motor, and when the contact is made with the worm gear 10, the intermittent This prevents the wiper motor from working.

그러나 상기 플레이트설치홈(11)에 릴레이플레이트(20)를 설치할 때 조립이 잘 이루어지지 않거나, 또는 조립된 상태에서 릴레이플레이트(20)의 플레이트부(21)에 형성된 밀착돌출부(21a,21b)가 들뜸으로 인해 접점에서 소리가 나거나 걸리게 되는등의 문제점이 있었다.However, when the relay plate 20 is installed in the plate installation groove 11, the assembly is not performed well, or the close contact protrusions 21a and 21b formed in the plate portion 21 of the relay plate 20 are assembled. Due to the lifting, there was a problem such as sound coming from the contact point.

이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출한 것으로, 플레이트설치홈에 릴레이플레이트를 설치할 때 플레이트부의 밀착돌출부를 하부로 일정각도 벤딩되도록 성형하여 조립함으로써, 밀착돌출부의 단부가 플레이트설치홈의 하부로 위치하도록 하여 접점이 워엄기어를 타고 릴레이플레이트로 올라갈 때 걸리는 것을 방지하도록 한 와이퍼모터용 워엄기어와 릴레이플레이트의 조립구조를 제공하는데 그 목적이 있다.In order to solve the problems as described above, the present invention is devised to assemble a contact portion of the plate portion by bending a certain angle downward when the relay plate is installed in the plate installation groove. It is an object of the present invention to provide an assembly structure of a worm gear and a relay plate for a wiper motor, which is positioned so as to prevent the contact from being caught when the worm gear is climbed into the relay plate.

상기와 같은 목적을 달성하기 위한 본 고안은, 워엄기어의 측면에 플레이트설치홈이 형성되는 한편, 이 플레이트설치홈에 도체인 릴레이플레이트가 끼워지는 와이퍼모터용 워엄기어와 릴레이플레이트의 조립구조에 있어서, 상기 플레이트설치홈에 릴레이플레이트의 평판부분인 플레이트부의 밀착돌출부를 하부로 일정각도 벤딩되도록 성형하여 조립한 것을 특징으로 한다.The present invention for achieving the above object is, in the assembling structure of the worm gear and the relay plate for the wiper motor, the plate mounting groove is formed on the side of the worm gear, the relay plate is fitted to the plate mounting groove. And forming and assembling the plate-protruding contact portion of the plate portion, which is a flat plate portion of the relay plate, to be bent at a predetermined angle downward.

이하 본 고안의 바람직한 실시예에 대해 첨부한 도면에 의거 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 고안의 1실시예에 따른 릴레이플레이트의 요부설명도이고, 도 2는 도 1의 외측조립부를 나타내는 설명도이며, 도 3은 도 1의 내측조립부를 나타내는 설명도로서, 종래 기술을 설명하는 도 5와 동일한 부위에는 동일한 참조부호를 붙이면서 그 설명은 생략한다.1 is an explanatory view of main parts of a relay plate according to an embodiment of the present invention, FIG. 2 is an explanatory view showing an outer assembly of FIG. 1, and FIG. 3 is an explanatory view showing an inner assembly of FIG. The same parts as in FIG. 5 to be described are given the same reference numerals and the description thereof will be omitted.

본 고안은, 외주면에 기어를 갖춘 워엄기어(10)의 측면에 소정형상의 플레이트설치홈(11)이 형성되는 한편, 이 플레이트설치홈(11)에 대응하는 도체인 릴레이플레이트(20)가 끼워지는 와이퍼모터용 워엄기어와 릴레이플레이트의 조립구조에 있어서, 상기 플레이트설치홈(11)에 릴레이플레이트(20)를 설치할 때 플레이트부(21)의 밀착돌출부(21a,21b)를 하부로 일정각도 벤딩되도록 성형하여 조립한 구조로 되어 있다.According to the present invention, a plate-mounting groove 11 having a predetermined shape is formed on the side of the worm gear 10 having gears on the outer circumferential surface thereof, while the relay plate 20 corresponding to the plate-mounting groove 11 is fitted. In the assembling structure of the worm gear for the wiper motor and the relay plate, the bending protrusions 21a and 21b of the plate portion 21 are bent at an angle downward when the relay plate 20 is installed in the plate mounting groove 11. It is molded to be assembled and assembled.

상기 밀착돌출부(21a,21b)의 벤딩은, 외측의 밀착돌출부(21a)의 경우 안쪽으로 도피홈(23)을 형성한 다음 벤딩함으로써 작업이 용이하도록 구성되어 있다,The bending of the close contact protrusions 21a and 21b is configured to facilitate the work by forming the escape grooves 23 inward in the case of the outer close contact protrusions 21a and then bending them.

따라서 상기 밀착돌출부(21a,21b)가 플레이트설치홈(11)의 하부로 위치하도록 소정각도로 벤딩하여 조립함으로써 스프링(도시않됨)에 의해 돌출되는 접점이 워엄기어(10)의 측벽을 타고 릴레이플레이트(20)로 올라갈 때 걸리는 것을 방지하게 된다.Therefore, the contact protrusions 21a and 21b are bent and assembled at a predetermined angle so as to be positioned below the plate installation grooves 11 so that the contacts protruding by the springs (not shown) ride on the sidewalls of the worm gear 10 on the relay plate. It is prevented from getting caught when going up to (20).

한편 도 4는 본 고안의 다른 실시예로, 워엄기어(30)의 플레이트설치홈(31)의 밀착부(31a)에 릴레이플레이트(20)의 단부인 밀착돌출부(41a)가 벤딩되어 조립됨으로써, 접점이 워엄기어(30)의 측벽을 타고 릴레이플레이트(40)로 올라갈 때 걸리는 것을 방지하게 된다.On the other hand, Figure 4 is another embodiment of the present invention, the close contact portion (41a) of the end of the relay plate 20 to the close contact portion 31a of the plate mounting groove 31 of the worm gear 30 is assembled by bending, The contact is prevented from being caught when climbing the side wall of the worm gear 30 to the relay plate 40.

상기와 같이 설명한 본 고안에 의하면, 스프링에 의해 돌출된 접점이 접촉되어 워엄기어의 상부에 조립된 릴레이플레이트위를 회전할 때 소리가 나거나 걸리는 것을 방지하는 효과가 있게 된다.According to the present invention as described above, when the contact projected by the spring is in contact with the rotation of the relay plate assembled on the upper portion of the worm gear there is an effect of preventing the sound or caught.
