摘要:
A wheelchair power-assisted wheel is arranged on a wheelchair. The wheelchair power-assisted wheel includes a substrate axially connected with the wheelchair. A power-driven wheel is arranged on a lower surface of a front part of the substrate and touches the ground. A power provider is arranged on an upper surface of a back part of the substrate and electrically connected with the power-driven wheel and provides power to the power-driven wheel whereby the power-driven wheel moves against the ground. The present invention is convenient for a sitter to move on a rough road or to move uphill. The power-driven wheel of the wheelchair power-assisted wheel moves against the ground without idling, so as to improve driving efficiency, which is more helpful in moving the sitter.
