도 1은 본 고안의 바람직한 실시예에 따른 자동차용 스티어링 휠을 개략적으로 도시한 종단면도이고, 도 2는 상기 스티어링 휠의 림 부위를 개략적으로 도시한 구성도이다.1 is a longitudinal sectional view schematically showing a steering wheel for a vehicle according to a preferred embodiment of the present invention, Figure 2 is a schematic diagram showing a rim portion of the steering wheel.
도 1 및 도 2에 도시된 바와 같이, 상기 스티어링 휠은 미도시된 인스트루먼트 패널에 고정되는 칼럼(12)에 설치되는 스틸 재질의 허브코어(10)와, 이 허브코어(10)의 림(14)의 외주면에 소정 두께로 성형되는 내층부(20)와, 이 내층부(20)의 외주면에 배치되는 가열부재(30), 및 이 가열부재(30)를 내층부(20)의 외주면에 묻히게 하는 외층부(40)를 구비한다.As shown in FIGS. 1 and 2, the steering wheel includes a steel hub core 10 installed in a column 12 fixed to an instrument panel not shown, and a rim 14 of the hub core 10. The inner layer portion 20 formed on the outer circumferential surface of the inner layer portion 20, the heating member 30 disposed on the outer circumferential surface of the inner layer portion 20, and the heating member 30 are buried on the outer circumferential surface of the inner layer portion 20. The outer layer part 40 is provided.
상기 허브코어(10)는 알루미늄 또는 마그네슘 재질로 제작된다. 허브코어(10)의 중앙 상부에는 혼커버(horn cover:18)가 결합되고, 중앙 하부에는 하부커버(19)가 결합된다. 또한, 허브코어(10)의 하부커버(19)에는 에어백, 혼 구조물 등을 구동하기 위해 축전지에 전원 연결된 소위, 컨택트 링(contact ring)과 같은 전원공급부(16)가 설치된다. 참조부호 15는 가열부재(40)를 선택적으로 단속하기 위한 바이메탈을 나타낸다.The hub core 10 is made of aluminum or magnesium material. A horn cover 18 is coupled to the central upper portion of the hub core 10, and a lower cover 19 is coupled to the central lower portion. In addition, the lower cover 19 of the hub core 10 is provided with a power supply unit 16 such as a so-called contact ring connected to a storage battery for driving an airbag, a horn structure, or the like. Reference numeral 15 denotes a bimetal for selectively interrupting the heating member 40.
상기 내층부(20)는 허브코어(10)의 림(14)의 외주면에 연질 우레탄 바람직하게는 발포성 우레탄으로 소정 두께로 저압 성형된다.The inner layer portion 20 is low pressure molded to a predetermined thickness of soft urethane, preferably foamed urethane, on the outer circumferential surface of the rim 14 of the hub core 10.
상기 가열부재(30)는 주로 탄소 프린팅 필름이 이용되고, 이외에도 구리선, 크롬선, 은분도료 등이 사용될 수도 있다. 상기 가열부재(30)는 미도시된 타이머에 의해 작동된 후 소정 시간 경과 후에 작동을 멈추도록 제어될 수도 있다.The heating member 30 is mainly used a carbon printing film, in addition to copper wire, chromium wire, silver powder coating may be used. The heating member 30 may be controlled to stop operation after a predetermined time after being operated by a timer not shown.
도 3a 및 도 3b는 도 2에 도시된 가열부재의 일 실시예를 개략적으로 도시한 단면도 및 평면도이다.3A and 3B are schematic cross-sectional views and plan views of an embodiment of the heating member illustrated in FIG. 2.
도 3a 및 도 3b에 도시된 바와 같이, 상기 탄소 프린팅 필름(32)은 폴리에스테르 필름으로 이루어진 기판층(34)과, 이 기판층(34)에 소정 형상으로 프린팅된 탄소 섬유층(36), 및 그 탄소 섬유층(36) 위에 도포된 접착층(38)을 포함한다. 또한, 상기 탄소 프린팅 필름(32)은 원형의 휠 형상에 적합하도록 재단가공이 용이하고 탄소 섬유층(36)의 두께에 따라 소정 온도가 결정되므로 온도제어가 용이한 특징이 있다.As shown in FIGS. 3A and 3B, the carbon printing film 32 includes a substrate layer 34 made of a polyester film, a carbon fiber layer 36 printed on the substrate layer 34 in a predetermined shape, and An adhesive layer 38 applied on the carbon fiber layer 36 is included. In addition, the carbon printing film 32 is easy to be cut to fit in the shape of a circular wheel, and a predetermined temperature is determined according to the thickness of the carbon fiber layer 36, so it is easy to control the temperature.
도 2의 Ⅳ-Ⅳ선 단면도인 도 4를 참조하면, 상기 탄소 프린팅 필름(32)은 내층부(20) 외주면에 방사상으로 약 90각도로 배치되어 림(14)의 중심에 대해 서로 대칭되도록 두쌍이 나란하게 배치된다. 따라서, 운전자가 스티어링 휠을 감싸 쥘 때 손바닥의 전체가 따뜻하게 유지될 수 있다.Referring to FIG. 4, which is a cross-sectional view taken along line IV-IV of FIG. 2, the carbon printing film 32 is disposed at about 90 degrees radially on the outer circumferential surface of the inner layer 20 so as to be symmetrical with each other with respect to the center of the rim 14. This is arranged side by side. Thus, the entire palm can be kept warm when the driver wraps around the steering wheel.
상기 외층부(40)는 내층부(20)의 외주면에 위치된 가열부재(30)가 묻힐 수 있도록 경질 우레탄, 바람직하기로는 발포성 경질 우레탄으로 성형된다. 여기서, 외층부(40)의 두께는 약 1.5mm 내지 2.5mm 범위 내에서 바람직하기로는 약 2.0mm가 되도록 저압으로 성형된다. 왜냐하면, 가열부재(30)의 가열 능력을 고려하여 너무 두껍거나 얇은 경우에 따른 부작용을 방지하기 위함이다. 상기 저압성형은 내층부(20)에 접착된 가열부재(30)가 밀려나지 않을 만큼의 소정 압력으로 성형하는 것을 의미한다.The outer layer portion 40 is formed of hard urethane, preferably foamed hard urethane so that the heating member 30 located on the outer circumferential surface of the inner layer portion 20 is buried. Here, the thickness of the outer layer portion 40 is molded at low pressure so that it is preferably about 2.0 mm in the range of about 1.5 mm to 2.5 mm. This is to prevent side effects due to being too thick or thin in consideration of the heating capability of the heating member 30. The low pressure molding means molding at a predetermined pressure such that the heating member 30 adhered to the inner layer part 20 is not pushed out.
도 5는 본 고안의 다른 실시예에 따른 스티어링 휠을 개략적으로 도시한 구성도이고, 도 6은 도 5의 Ⅵ-Ⅵ선 단면도이다. 도 1 및 도 2에서 설명된 참조부호와 동일한 구성요소는 동일한 기능을 가진 동일부재이다.5 is a configuration diagram schematically showing a steering wheel according to another embodiment of the present invention, Figure 6 is a cross-sectional view taken along the line VI-VI of FIG. The same components as those described in FIGS. 1 and 2 are the same members with the same functions.
본 실시예는 가열부재(50)를 구리선, 크롬선, 은분도료, 탄소섬유 등을 이용하여 나선형으로 내층부(20)의 외주면에 권회시키고, 외층부(60)를 가죽 등의 피복제로 입혀 마감한 것을 도시한 것이다. 여기서, 상기 가죽으로 구성된 외층부(60)의 두께도 전기 실시예의 발포 우레탄 재질과 같이 약 1.5mm 내지 2.5mm 범위 내에서 약 2.0mm 범위의 두께를 가지는 것이 바람직하다.In this embodiment, the heating member 50 is wound around the outer circumferential surface of the inner layer part 20 in a spiral manner using copper wire, chromium wire, silver powder coating, carbon fiber, etc., and the outer layer part 60 is coated with a coating material such as leather and finished. It shows what you did. Here, it is preferable that the thickness of the outer layer part 60 made of leather also has a thickness in the range of about 2.0 mm in the range of about 1.5 mm to 2.5 mm, as in the foamed urethane material of the above embodiment.
상기 구성을 가진 본 고안의 자동차용 스티어링 휠은 림 부위가 차갑게 되더라도 타이머를 작동시켜 조기에 림부 주위를 따뜻하게 할 수 있다. 따라서, 손이 시린 상태에서 운전하는 것을 예방하여 안전사고를 줄일 수 있다.Steering wheel for a vehicle of the present invention having the above configuration can be warmed around the rim early by operating the timer even if the rim is cold. Therefore, it is possible to reduce the safety accident by preventing the hand driving in a cold state.
