The present invention relates to a lens structure of a rear combination lamp for a vehicle, and more particularly, in the conventional butt method, the boundary line is formed by excluding the stepped portion inside the rear combination lamp and instead rounding the stepped portion gently. By making it invisible, it greatly improves the appearance of the product, and unlike the existing overlay method, the overlapping section of the front and rear is eliminated to prevent light leakage, and also reduce the weight and cost of the automotive rear combination lamp lens. It's about structure.
일반적으로, 자동차용 리어 콤비네이션 램프(rear combination lamp)의 렌즈는 대부분 플라스틱 사출로 제조하게 된다. In general, lenses of rear combination lamps for automobiles are mostly manufactured by plastic injection.
상기 리어 콤비네이션 램프의 경우 후미등, 제동등, 후진등, 방향지시등 등의 여러 기능들이 하나의 램프에 집합되어 있고, 각 기능별로 법규에서 정한 컬러를 나타내기 위하여 적색, 투명, 호박색 등의 서로 다른 수지로 제조하게 된다.In the case of the rear combination lamp, various functions such as tail light, brake light, reversing light, direction indicator light, etc. are collected in one lamp, and different resins such as red, transparent, and amber color are used to represent the color prescribed by the law for each function. To manufacture.
여기서, 상기 리어 콤비네이션 램프 렌즈의 제조공법은 주로, 중형차에는 오버레이(over-lay)공법으로 구성하고, 소형차에는 맞대기 또는 인서트(insert)공법을 적용하여 사용하고 있다.Here, the manufacturing method of the rear combination lamp lens is mainly composed of an overlay method for a medium-sized car, but a butt or insert method is applied to a small car.
상기 오버레이공법은 도 5와 도 6에 도시된 바와 같이, 베이스가 되는 클리어 렌즈(110)에 다른 컬러 렌즈(120)를 내면에 한번 더 사출하여 부착하는 형태로 일부구간에서 렌즈가 전후로 중복되어 있다.In the overlay method, as shown in FIGS. 5 and 6, another color lens 120 is injected into and attached to the inner surface of the clear lens 110 as a base, and the lenses overlap each other in some sections. .
또한, 상기 맞대기공법은 도 7과 도 8에 도시된 바와 같이, 클리어 렌즈(110')와 컬러 렌즈(120')를 각각 상하로 서로 맞대어 접합하는 공법이다. In addition, as shown in FIGS. 7 and 8, the butt method is a method of bonding the clear lens 110 'and the color lens 120' to each other by bonding them up and down.
그런데, 상기 오버레이공법은 제품의 외관은 깨끗하나 접합구조가 복잡하여 정밀한 금형가공이 요구되고, 또한 완제품의 두께 증가로 인하여 중량 및 제조비용이 상승할 뿐만 아니라, 빛이 렌즈를 통해 산란시 렌즈부분이 두꺼워 그 빛이 누광되는 문제점이 있다.However, in the overlay method, the appearance of the product is clean but the bonding structure is complicated, so that precise mold processing is required, and the weight and manufacturing cost not only increase due to the increase in the thickness of the finished product, but also the lens portion when light is scattered through the lens. This thick, there is a problem that the light is leaked.
한편, 상기 맞대기공법은 접합구조가 단순하여 정밀한 금형 가공이 요구되지는 않지만, 경계선 부분이 계단 형상부(130')로 이루어져 상기 경계선이 여러개 생기게 되므로 외관이 불량하여 제품의 고급감이 저하되는 문제점이 있다. On the other hand, the butt method does not require precise mold processing due to the simple joining structure, but the boundary part is made of a stepped portion 130 'so that the boundary line is generated, so the appearance is poor and the quality of the product is deteriorated. There is this.
따라서, 본 발명은 상기와 같은 문제점을 해결하기 위해 발명한 것으로서, 기존의 맞대기공법에서의 계단형상부를 완만하게 라운딩 처리하여 경계선이 보이지 않도록 형성하고, 기존의 오버레이공법에서의 전후로 중복되는 구간을 삭제하여 중량 및 비용을 절감할 수 있는 자동차용 리어 콤비네이션 램프의 렌즈구조를 제공하는데 그 목적이 있다. Therefore, the present invention was invented to solve the above problems, by gently rounding the stepped portion in the conventional butt method to form a boundary line is not visible, and to delete the overlapping section before and after the existing overlay method The purpose of the present invention is to provide a lens structure of a rear combination lamp for automobiles that can reduce weight and cost.
