Description

차량용 도어 스텝 및 그 제조방법{door step for vehicle and method of forming the same}Door step for vehicle and method of manufacturing the same

본 발명은 장식 벤딩 포일 플레이트와 예열된 섬유를 동시에 인서트 압착한 채 섬유의 배면에 브라켓을 사출 성형하여 경량화율을 극대화한 차량용 도어 스텝 및 그 제조방법에 관한 것이다. The present invention relates to a door step for a vehicle in which a decorative bending foil plate and a preheated fiber are simultaneously insert-pressed and a bracket is injection-molded on the back of the fiber to maximize the weight reduction rate, and a manufacturing method thereof.

일반적으로, 차량의 도어 스텝은 평소에는 외부로 노출되지 않지만, 탑승자가 탑승을 위해 차량 도어를 개방하는 경우 차량 바디 측에 장착되어 탑승자로 하여금 고급스러움을 느낄 수 있도록 하는 장식품이다.In general, the door steps of the vehicle are not normally exposed to the outside, but are mounted on the vehicle body side when the occupant opens the vehicle door for boarding, so that the occupant can feel the luxury.

또한, 차량의 도어 스텝은 RV 차량과 같은 지상고가 높은 차량에 적용하게 되면, 탑승자의 탑승을 보조하는 발판의 역할을 하기도 한다.In addition, when the door step of the vehicle is applied to a vehicle having a high ground clearance such as an RV vehicle, it may serve as a footrest to assist the occupant on board.

차량의 도어 스텝은 사출 기재에 스틸로 이루어진 장식 벤딩 포일 플레이트를 조립하여 제작되는데, 이러한 플레이트에는 장식용 패턴 식각, 문자부 식각, 광택부 연마, 부식 방지용 방청 코팅 등의 가공이 포함되어 있기 때문에, 중형차급 이상에만 선택적으로 스틸 재질의 플레이트가 적용되며, 저가의 차량에는 별도의 플레이트 없이 사출 기재만 적용되는 실정이다.Vehicle door steps are manufactured by assembling a decorative bending foil plate made of steel on an ejected base material, and these plates include processing such as decorative pattern etching, character part etching, polished part polishing, and anti-corrosion coating. Steel plates are selectively applied only to grades and above, and only injection materials are applied to low-cost vehicles without a separate plate.

그러나, 사출 기재에 스틸 재질의 플레이트로 이루어진 도어 스텝의 경우 스틸 가공비에 따른 제작 비용의 부담뿐만 아니라, 사출 기재와 스틸 재질의 플레이트 사이의 단차가 발생하여 외관상 통일감이 저하될 수 있다.However, in the case of a door step made of a plate made of steel on the injection substrate, not only the burden of manufacturing cost according to the steel processing cost, but also a step between the injection substrate and the plate made of steel may occur, thereby deteriorating a sense of unity in appearance.

즉, 상기와 같은 도어 스텝(1)의 구조는 도 1 및 도 2에 도시된 바와 같이 사출 기재(2)와 장식 벤딩 포일 플레이트(3)가 각각 별물로 제작한 후 작업자가 물리적으로 체결하여야 하기 때문에, 체결 품질에 따라 부품 경계면에 단차가 존재할 수 있고, 디자인 통일성이 저하될 수 있으며, 그에 따라 스틸 가공 및 조립에 따른 원가부담이 발생하여 중형 이상의 차량에만 적용되는 문제가 있다. That is, the structure of the door step 1 as described above requires that the injection base material 2 and the decorative bending foil plate 3 be separately manufactured as shown in FIGS. 1 and 2 and then physically fastened by the operator. Therefore, depending on the quality of the fastening, there may be a step at the boundary of the part, and design uniformity may be deteriorated. Accordingly, there is a problem that is applied only to medium-sized or larger vehicles due to a cost burden due to steel processing and assembly.

또한, 사출 기재(2)와 벤딩 포일 플레이트(3)의 조립성을 위하여 선접촉을 시키는데, 그 결과 벤딩 포일 플레이트(3)와 사출 기재(2) 사이에 도 2와 같은 공간(s)이 발생하게 되고, 외부 충격에 의한 찍힘을 예방하기 위하여 장식 벤딩 포일 플레이트(3)의 두께를 증대하여 찍힘을 최대한 예방하기 때문에 원가 및 무게의 상승을 요한다. In addition, line contact is made for the assembling property of the injection substrate 2 and the bending foil plate 3, as a result of which a space s as shown in FIG. 2 is generated between the bending foil plate 3 and the injection substrate 2 And, in order to prevent stamping due to external impact, the thickness of the decorative bending foil plate 3 is increased to prevent stamping as much as possible, requiring an increase in cost and weight.

이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명한다. Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 3 및 도 4는 본 발명의 바람직한 실시예에 따른 차량용 도어 스텝의 단면도 및 공정도이다. 3 and 4 are cross-sectional views and process diagrams of a door step for a vehicle according to a preferred embodiment of the present invention.

본 발명의 실시예에 따른 차량용 도어 스텝(10)은 도 3에 도시한 바와 같이, 장식 벤딩 포일 플레이트(11)와, 장식 벤딩 포일 플레이트(11)의 배면에 전면이 압착 접합되는 섬유(13)와, 섬유(13)의 배면에 사출 성형되는 브라켓(15)을 포함한다. The vehicle door step 10 according to the embodiment of the present invention includes a decorative bending foil plate 11 and a fiber 13 on which the front surface is press-bonded to the rear surface of the decorative bending foil plate 11 as shown in FIG. 3. And, it includes a bracket 15 that is injection-molded on the back of the fiber (13).

즉, 장식 벤딩 포일 플레이트(11)와 섬유(13)가 동시에 인서트 압착되는 면접촉으로 인해 밀착되어 박막 포일, 경량화 섬유 등의 적용이 가능하여 중량을 절감시킬 수 있다. That is, the decorative bending foil plate 11 and the fiber 13 are in close contact due to the surface contact in which the insert is pressed at the same time, so that a thin film foil or a lightweight fiber can be applied, thereby reducing weight.

이러한 차량용 도어 스텝(10)의 제조방법을 도 4를 참조하여 설명한다. A method of manufacturing the door step 10 for a vehicle will be described with reference to FIG. 4.
