Abstract

The invention discloses a power driving device for a manual wheelchair. A lateral edge of a frame of the wheelchair is provided with a seat which can swing for displacement; the seat is provided with a drum set which can be driven by a driving source to rotate; the drum set can be made to swing for displacement along with the seat to be joined to a main wheel of the wheelchair so as to perform transmission; the seat is additionally connected with an engaging and disengaging mechanism to control the seat to do reciprocal swing displacement and drive the drum set to be joined to or separated from the main wheel of the wheelchair so as to switch a driving mode of the wheelchair; and thus, the driving mode of the wheelchair is switched by using the engaging and disengaging mechanism, power can be provided to drive the manual wheelchair, easiness in operation and convenience in folding of the manual wheelchair can be guaranteed, and further, the practical benefit for convenience in use of the wheelchair can be greatly improved.
