Description

차량용 룸미러 베이스의 제조방법 및 그 제품Manufacturing method of vehicle room mirror base and its products

본 발명은 열경화성수지를 이용하여 차량의 전면 유리에 부착한 상태로 룸미러를 설치하기 위한 차량용 룸미러 베이스의 제조방법 및 그 제품에 관한 것이다.The present invention relates to a method of manufacturing a room mirror base for a vehicle for installing a room mirror in a state of being attached to a windshield of a vehicle using a thermosetting resin, and a product thereof.

일반적으로 룸미러는 운전자가 차량 뒤쪽의 움직임을 감시하기 위한 것으로서 차량 안쪽의 운전석과 조수석 사이에 설치되는 것이다.In general, the room mirror is for the driver to monitor the movement behind the vehicle and is installed between the driver's seat and the passenger seat inside the vehicle.

상기 룸미러를 설치하기 위한 구조는 대한민국 공개실용신안 제20-1998-0060157호(1998.11.05. 공개)에 개재된 바와 같이 차량의 헤더 패널에 룸미러를 직접 결합하는 방식이었고, 최근에는 도 1에 도시된 바와 같이 열경화성수지를 이용하여 차량 전면 유리에 룸미러 베이스를 부착한 상태에서 상기 룸미러 베이스에 룸미러를 끼우거나 체결하는 방식으로 개발되고 있다.The structure for installing the room mirror was a method of directly connecting the room mirror to the header panel of the vehicle as disclosed in the Republic of Korea Utility Model Model No. 20-1998-0060157 (published on November 5, 1998), and recently, Figure 1 As shown in the drawing, a room mirror base is attached to a room mirror base by attaching or fastening the room mirror base in a state in which a room mirror base is attached to a vehicle front glass using a thermosetting resin.

이에, 상기 종래 룸미러 베이스는 다음과 같은 문제점이 있다.Thus, the conventional room mirror base has the following problems.

첫째, 종래 룸미러 베이스는 스테인리스 합금(Stainless alloy)을 이용하여 소결 성형되기 때문에 소결의 특성상 수축의 변화가 커서 불량 발생률이 높은 단점이 있다.First, since the conventional room mirror base is sintered and formed using a stainless alloy, a shrinkage change is large due to the characteristics of sintering, and thus a defect occurrence rate is high.

둘째, 종래 룸미러 베이스는 스테인리스 합금(Stainless alloy)을 이용하여 소결 성형되기 때문에 열경화성수지와의 접착력이 떨어지는 단점이 있다. 즉, 상기 열경화성수지를 이용한 룸미러 베이스의 접착은 약 140℃의 온도에서 약 7시간 가열하여 상기 열경화성수지를 경화시키는 과정으로 이루어지는데, 이 경우 상기 열 조건에서도 룸미러 베이스에는 아무런 변화가 발생하지 않기 때문에 상기 열경화성수지와 룸미러 베이스 사이에 뚜렷한 경계를 형성하면서 상호 접착력이 약할 수밖에 없는 것이다. 그러므로 종래에는 차량의 갑작스런 충격이나 진동 또는 룸미러 자체의 무게 등 여러 요인에 의해 상기 룸미러 베이스가 열경화성수지로부터 떨어질 수 있고, 이 경우 떨어진 룸미러에 의해 운전자가 다치거나 교통사고를 유발할 수 있기 때문에 상기 열경화성수지와 룸미러 베이스 사이의 접착력을 높이기 위한 기술의 개발이 요구되고 있다.Second, since the conventional room mirror base is sintered and formed using a stainless alloy, the adhesive strength with the thermosetting resin is inferior. That is, the adhesion of the room mirror base using the thermosetting resin consists of a process of curing the thermosetting resin by heating at a temperature of about 140 ℃ for about 7 hours, in which case no change occurs in the room mirror base even under the thermal conditions. Since it forms a distinct boundary between the thermosetting resin and the room mirror base, mutual adhesion is inevitably weak. Therefore, in the related art, the room mirror base may be separated from the thermosetting resin by various factors such as a sudden shock or vibration of the vehicle or the weight of the room mirror itself, and in this case, the driver may be injured or induce a traffic accident by the fallen room mirror. There is a demand for the development of a technique for increasing the adhesive force between the thermosetting resin and the room mirror base.

세째, 종래 룸미러 베이스는 스테인리스 합금(Stainless alloy)을 이용하여 소결 성형되기 때문에 무거운 단점이 있다. 즉, 자동차의 개발에서 최근에는 자동차의 안전성을 유지하면서도 차체 무게를 줄이기 위한 연구가 활발하게 진행되고 있는데, 이렇게 차체 무게를 줄이기 위해서 어느 한 구성의 무게를 대폭 낮추기는 어렵기 때문에 주로 여러 구성의 무게를 최소화함으로써 전체 무게를 줄이는 방법으로 연구중이다. 그런데 종래 룸미러 베이스는 금속재질로 형성되어 있어서 크기나 용도에 비하여 중량이 매우 큰 단점이 있고, 이를 위해 상기 룸미러 베이스의 크기를 줄이려면 우선 접착면적이 줄어드는데 이렇게 접착면적을 줄이는 것은 안전성에 문제가 있기 때문에 경량화가 어려운 것이다.Third, the conventional room mirror base has a heavy disadvantage since it is sintered and molded using a stainless alloy. In other words, in the development of automobiles, research is being actively conducted to reduce the weight of the vehicle while maintaining the safety of the vehicle. In order to reduce the weight of the vehicle, it is difficult to significantly reduce the weight of one component. Is minimizing the overall weight by minimizing the However, the conventional room mirror base is formed of a metal material, and thus has a disadvantage in that the weight is very large compared to the size and the use. For this purpose, in order to reduce the size of the room mirror base, the adhesion area is reduced first. Because of the problem, it is difficult to reduce the weight.
