The present invention relates to a wheelchair towing electric bicycle comprising: a bicycle body; a bicycle connecting member (10) to which a bicycle body pipe (A1) having a rotation shaft (110) of a bicycle handle inserted thereinto is coupled; a wheelchair connecting member (20) to which a wheelchair handle is coupled; a coupling member (40) having one side coupled to the wheelchair connecting member (20), and supporting the bicycle connecting member (10) to be rotated relative to the wheelchair connecting member (20) in a horizontally direction of a longitudinal direction of a bicycle; a tilt detecting unit for detecting a horizontal tilt of the bicycle; and a motor driving control unit for controlling driving of a driving motor. The motor driving control unit controls driving of the driving motor in accordance with a horizontal tilt value of the bicycle detected by the tilt detecting unit during traveling, and prevents a wheelchair from overturning when a bicycle direction is changed by allowing the bicycle connecting member (10) to be rotated relative to the wheelchair connecting member (20).

    본 발명은 휠체어견인 전기자전거에 관한 것으로서, 자전거 몸체; 자전거핸들의 회전축(110)이 삽입되는 자전거몸체파이프(A1)가 결합되는 자전거 연결부재(10); 휠체어 손잡이가 결합되는 휠체어 연결부재(20); 일측이 상기 휠체어 연결부재(20)에 결합되며, 상기 자전거 연결부재(10)가 상기 휠체어 연결부재(20)에 대하여 자전거 길이방향의 좌우로 상대적인 회전운동이 가능하도록 상기 자전거 연결부재(10)를 지지하는 결합부재(40); 자전거의 좌,우 기울기를 검출하는 기울기 검출부; 및 구동모터의 구동을 제어하는 모터 구동 제어부;를 포함하고, 상기 모터 구동 제어부는 주행시 상기 기울기 검출부로 부터 검출된 상기 자전거의 좌,우 기울기값에 따라 상기 구동모터의 구동을 제어하며, 상기 자전거 연결부재(10)가 상기 휠체어 연결부재(20)에 대하여 상대적인 회전운동이 가능하도록 하여 자전거 방향전환시 휠체어의 전복을 방지하는 것을 특징으로 한다.
