Abstract
An electric wheelchair is disclosed. The electric wheelchair includes a main frame correspondingly pivoted with a foldable chair while the folding of the chair connects with an accessory tip wheel. Moreover, the main frame is disposed with main wheels and a front wheel set arranged on front of the main wheel correspondingly on each of two sides thereof. A footrest that is pulled out or stored in the main frame is arranged between the two front wheel sets. In use, the footrest is pulled out of the main frame and the chair is moved and unfolded. At the same time, the accessory tip wheel tilted a little angle is extended out of the main frame by a connecting member. Thereby the problem caused by movement of the center of gravity of the wheelchair while moving can be solved and the safety of users is ensured.
