Abstract

The wheelchair mechanism for a car that is proposed in this study primarily consists of a transfer mechanism and storage mechanism. The wheelchair transfer mechanism consists of a manipulator installed in the roof of a car, and performs the function of transferring the wheelchair from the driver's seat to the trunk. The wheelchair storage mechanism consists of a lifting hoist installed in the trunk of car, and performs the function of storing the transferred wheelchair in the trunk and safely fastening it in place. This study analyzed and reviewed various manipulators, including a vertical type, Scara type, and telescopic type, with the goal of selecting the best type of manipulator for the wheelchair transfer mechanism. The telescopic type was selected and applied because of its good load support and storage capabilities. In addition, with regard to the wheelchair storage mechanism, a slide hoist type that used a slide rail and lift wire and a rotating link hoist type that used a rotating mechanism consisting of a worm gear and link were analyzed and reviewed. The slide hoist type was selected and applied because it had an advantage in relation to trunk space utilization. This study proposed a wheelchair transfer mechanism for a car to support a conventional wheelchair user's movements, and in order to conform to the structure of a domestic welfare car for the disabled.

본 연구에서 제안된 차량용 휠체어 수송메커니즘은 크게 이송메커니즘과 수납메커니즘으로 구성된다. 여기서 휠체어 이송메커니즘은 매니퓰레이터로 구성되며, 차량의 루프에 설치되어 운전석에서 트렁크의 위치까지 휠체어를 이송하는 기능을 한다. 휠체어 수납메커니즘은 리프팅 호이스트로 구성되며, 차량의 트렁크에 설치되어 이송된 휠체어를 트렁크 내부로 수납하고 안전하게 고정하는 기능을 한다. 본 연구에서는 휠체어 이송메커니즘의 조건을 고려한 매니퓰레이터의 방식선정을 위해 수직방식, 수평방식, 텔레스코픽방식 등에 대하여 분석하고 검토하여 하중지지에 강하고 수납보관에 유리한 텔레스코픽방식을 선정하여 적용하였다. 또한 휠체어 수납메커니즘에서는 슬라이드 레일과 리프트와이어에 의한 슬라이드 호이스트방식과 웜기어와 링크로 구성된 회전메커니즘에 의한 회전링크 호이스트방식에 대하여 분석하고 검토하여 트렁크 공간 활용에 유리한 슬라이드 호이스트방식을 선정하여 적용하였다. 본 연구에서 제안된 차량용 휠체어 이송메커니즘은 기존의 휠체어 이용자 이동지원을 위한 차량용 휠체어 이송시스템의 단점을 해소하고 국내 장애인복지차량 구조에 부합하도록 제안하였다.
