자동차용 아웃사이드미러의 쿼터 이너커버 {Quarter Inner Cover of Outside Mirror for Car}Quarter Inner Cover of Outside Mirror for Car}

본 발명은 자동차용 아웃사이드미러의 쿼터 이너커버에 관한 것으로서, 더욱 상세하게는 파스너를 먼저 사출한 후 이 파스너를 쿼터 이너커버 금형에 세팅하여 쿼터 이너커버를 사출하는 이중사출 적용으로 금형 구조상 언더컷을 해결할 수 있는 자동차용 아웃사이드미러의 쿼터 이너커버에 관한 것이다.The present invention relates to a quarter inner cover of an automotive exterior mirror, and more particularly, a fastener is first injected and then the fastener is set in a quarter inner cover mold to inject a quarter inner cover, thereby applying an undercut in mold structure. It is related with the quarter inner cover of the automotive exterior mirror which can be solved.

일반적으로 자동차의 아웃사이드미러는 운전석과 조수석의 측면에 각각 부착하여 후방을 주시하며 운전자가 뒤돌아 보지 않더라도 운전이 용이하도록 하기 위하여 사용하고 있다. In general, the outside mirror of the car is attached to the side of the driver's seat and the passenger's seat to look at the rear and is used for easy driving even if the driver does not look back.

이러한 아웃사이드미러는 쿼터 이너커버와 파스너(fastener)를 이용하여 조립을 하는바, 도 1a 및 도 1b에 도시된 바와 같이, 쿼터 이너커버(1)에 돌출 형성된 보스부(2)에 파스너(3)를 상부에서 외삽하여 결합한다.The outside mirror is assembled using a quarter inner cover and a fastener, and as shown in FIGS. 1A and 1B, the fastener 3 is formed on the boss portion 2 protruding from the quarter inner cover 1. ) Extrapolate from the top to join.

상기 보스부(2)의 내부에는 길이방향으로 구멍(2a)이 형성되고 상부 일부가 절개되어 탄성을 갖게 되며, 상단부에는 결착돌기(2b)가 형성된다.Inside the boss portion 2, a hole 2a is formed in the longitudinal direction and a portion of the upper portion is cut to have elasticity, and a binding protrusion 2b is formed at the upper end portion.

상기 파스너(3)의 도중에는 상기 결착돌기(2b)가 끼워지는 결착홀(3a)이 형 성된다.In the middle of the fastener 3, a binding hole 3a into which the binding protrusion 2b is fitted is formed.

이에 의해 상기 보스부(3)의 상부가 내측으로 좁아진 상태에서 파스너(3)에 끼워진 후 결착홀(3a)까지 삽입되면 상부가 벌어지면서 결착돌기(2b)가 결착홀(3a)에 끼워져 빠지지 않게 된다.As a result, when the upper portion of the boss portion 3 is inserted into the fastener 3 in a state in which the upper portion is narrowed inward, the upper portion of the boss portion 3 is inserted into the binding hole 3a so that the binding protrusion 2b is inserted into the binding hole 3a so as not to be pulled out. do.

상기 보스부(2)가 끼워지지 않은 나머지 부분의 파스너(3) 내주연에는 나사산이 형성되어 아웃사이드미러(4) 마운팅용 볼트(5)가 나사결합하며 파스너(3) 내주연의 상부에는 체결력을 향상시키기 위한 걸림턱(3b)이 형성된다.A thread is formed in the inner circumference of the fastener 3 of the remaining portion where the boss portion 2 is not inserted, and the outer mirror 4 mounting bolt 5 is screwed to the upper part of the inner circumference of the fastener 3. A locking step 3b is formed to improve the pressure.

상기 파스너(3)의 걸림턱(3b) 구조를 적용하기 위해서는 사출 금형 구조상 언더컷이 발생하여 1피스(piece)에 의한 성형이 불가능하다.In order to apply the structure of the latching jaw 3b of the fastener 3, an undercut occurs in the injection mold structure, and molding by one piece is impossible.

상기 언더컷은 사출 성형 후 금형이 분리되는 방향으로 형성된 제품의 일부분으로서 원활한 금형의 분리를 방해하는 요소가 되는 것이다.The undercut is a part of the product formed in the direction in which the mold is separated after the injection molding is to be an element that prevents the smooth separation of the mold.

이와 같은 종래 아웃사이드미러의(4) 체결 구조는 쿼터 이너커버(1)와 같은 파스너(3)의 재질(plastic)상 볼트(5)의 나사결합에 의한 마모 발생으로 재사용시 체결력이 떨어진다.The fastening structure of the conventional outer mirror (4) is a fastening force when reused due to the wear caused by the screwing of the bolt (5) on the plastic (plastic) of the fastener (3) such as the quarter inner cover (1).

그리고 걸림턱(3b)의 마모로 인한 체결력 부족과, 쿼터 이너커버(1)와 파스너(3)간 유격으로 쿼터 이너커버(1)와 상관 부품 간에 도 2a 및 도 2b의 화살표와 같은 매칭 불량이 발생하며, 보스부(2)의 급격한 두께 변화로 촉감이 떨어지는 문제점이 있었다.In addition, there is a lack of fastening force due to wear of the locking jaw 3b and a gap between the quarter inner cover 1 and the fastener 3 and the matching failure such as the arrow of FIGS. 2A and 2B between the quarter inner cover 1 and the correlated parts. There was a problem that the touch falls due to the sudden thickness change of the boss portion (2).

본 발명은 상술한 문제점을 해결하기 위하여 안출된 것으로서, 걸림턱 구조를 위해 별물에 의한 이중사출 적용으로 사출 금형 구조상의 언더컷을 해결하고, 파스너의 재질을 연질로 하여 탈부착시 걸림턱의 파손을 방지할 수 있으며, 쿼터 이너커버의 두께를 균일하게 하여 촉감을 향상시킬 수 있을 뿐만 아니라 쿼터 이너커버와 파스너간 일체형 적용으로 상관 부품과 우수한 매칭성을 유지할 수 있는 자동차용 아웃사이드미러의 쿼터 이너커버를 제공하는데 그 목적이 있다.The present invention has been made in order to solve the above problems, to solve the undercut on the injection mold structure by applying a double injection by a separate object for the locking jaw structure, to prevent the breakage of the locking jaw when detachable by the soft material of the fastener. In addition to improving the feel by making the thickness of the quarter inner cover uniform, the quarter inner cover of the automotive exterior mirror that can maintain excellent matching with the related parts by the integrated application between the quarter inner cover and the fastener The purpose is to provide.

상술한 목적을 달성하기 위한 본 발명에 따른 자동차용 아웃사이드미러의 쿼터 이너커버는, 아웃사이드미러 마운팅용 볼트를 체결하기 위한 파스너를 사출에 의해 성형한 후, 이 성형된 파스너를 쿼터 이너커버 금형에 세팅하여 쿼터 이너커버를 사출하는 이중사출에 의해 파스너가 쿼터 이너커버에 일체화되는 것을 특징으로 한다.Quarter inner cover of the automotive exterior mirror according to the present invention for achieving the above object, after molding the fastener for fastening the outer mirror mounting bolts by injection, the molded inner fastener to the quarter inner cover mold The fastener is integrated into the quarter inner cover by double injection to eject the quarter inner cover by setting to.

상술한 과제 해결 수단에 의하면, 사출 금형 구조상의 언더컷을 해결하고 탈부착시 걸림턱의 파손을 방지할 수 있으며, 촉감을 향상시킬 수 있을 뿐만 아니라 쿼터 이너커버와 상관 부품 간의 우수한 매칭성을 유지할 수 있다.According to the above-mentioned problem solving means, it is possible to solve the undercut on the injection mold structure and to prevent the breakage of the jamming jaw when detaching and detaching, to improve the feel and to maintain excellent matching between the quarter inner cover and the correlated parts. .

이하 본 발명의 실시예에 대하여 첨부된 도면을 참고로 그 구성 및 작용을 설명하기로 한다.Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.
