A buffer structure, simplified for an electric wheelchair, includes a frame, two operating units, two front guide units, two front shock absorbers, two rotation preventing units, and two rear shock absorbers. The two front guide units are placed on both sides of the frame, and each of the units includes a front guide wheel, a front buffer arm, and a twisting spring. The two front and rear shock absorbers are connected with the frame. The two rotation preventing units are placed on both sides of the frame. When the front guide arms pivot the front guide wheels, the twisting springs generate repulsive force, preventing the frame from turning over, and improve stability. When the buffer structure passes through an uneven road, the front and rear shock absorbers remove a shock to the frame, and improve comfortableness.COPYRIGHT KIPO 2016
