Claims (5)
- 인체의 하중을 감지하는 하중 감지부;
상기 하중 감지부가 감지한 하중에 상응한 회전 구동력을 발생시키는 액추에이터;
상기 회전 구동력을 전달받아 직선 운동으로 변환하는 리드스크류 구동부;
상기 액추에이터를 수납하고, 상기 리드스크류 구동부와 체결되며, 인체와 결합되는 상부 프레임;
수동 의족이 부착되고, 상기 리드스크류 구동부와 상기 상부 프레임과 각각 체결되어 상기 리드스크류 구동부의 직선 운동에 의해 상기 수동 의족을 회전 운동시키는 하부 프레임; 및
상기 액추에이터와 체결되는 제1 풀리, 상기 리드스크류 구동부와 체결되는 제2 풀리와 체결되어, 상기 액추에이터의 회전 구동력을 상기 리드스크류 구동부로 전달하는 타이밍 벨트;를 포함하되,
상기 상부 프레임은 상기 리드스크류 구동부와 제1 체결 핀에 의해 체결되고, 상기 하부 프레임은 상기 리드스크류 구동부와 하부 제2 체결 핀에 의해 체결되고, 상기 상부 프레임과 제3 체결 핀에 의해 체결되고,
상기 리드스크류 구동부는 리드스크류(Lead-screw)와 상기 리드스크류가 삽입되는 너트(Nut)를 포함하되, 상기 타이밍 벨트 및 풀리 구조를 통해 상기 액추에이터의 측부에 나란히 연결 및 배치되고,
상기 수동 의족 또는 상기 하부 프레임은 상기 리드스크류 구동부의 직선 운동에 의해 상기 제3 체결 핀을 축으로 하여 회전 운동함으로써,
상기 리드스크류 구동부의 길이가 길어질 경우에는 수동의족이 발등 쪽으로 회전하여 발등 굽힘(Dorsiflexion) 동작이 수행되며, 길이가 줄어들 경우에는 수동의족이 발바닥 쪽으로 회전하는 발바닥 굽힘(Plantarflexion) 동작이 수행되는 것을 특징으로 하는 능동 하퇴 의지 장치. - 삭제
