Abstract
An electrical driving system which may be conveniently installed on or removed from a wheelchair is provided. The electrical driving system comprises a coupling assembly which houses a storage battery and a control circuit board. The system also comprises a holder assembly which houses motors and planetary gears which drive a pair of drive wheels. The electrical driving system is installed on the wheelchair by coupling together an upper connector and a lower connector of the coupling assembly about each of the tipping levers of the wheelchair. The coupling assembly includes a plurality of coupling pins, finger elements, and set pins, the appropriate coupling of which enables each finger element to be pivotally displaced to selectively press or release an upper connector to correspondingly grip or release the given tipping lever captured between that upper connector and a lower connector. A control column is secured to an armrest of the wheelchair, and a control circuit board is couple thereto for selectively actuating the drive motors responsive to control column manipulation by the wheelchair's user.
