Patent ID: 7083013

Claim:
A self-leveling and balancing vehicle comprising: a moving and driving mechanism including two longitudinal moving seats formed at two sides thereof, a connecting frame extending to and connecting said longitudinal moving seats, and two sector gears respectively installed on said two longitudinal moving seats; a driving motor fixed under the top of said connecting frame, the driving motor having a driving shaft extending to said two sector gears; two level driving gears installed on two ends of said driving shaft and engaged with said two sector gears; a balance driving gear box installed on said driving shaft, the balance driving gear box having an output shaft extending to said connecting frame for free rotation, and two driven gears, each driven gear installed on each of two ends of said output shaft; a base including two guiding rails or guiding grooves disposed in parallel with a longitudinal axis of the vehicle, said longitudinal moving seats mounted on the two guiding rails or guiding grooves, two racks fixed between and disposed in parallel with the two guiding rails or guiding grooves, the driven gears on said output shaft are engaged with the two racks; and wherein when the vehicle is running up or down a slope, the driving motor drives the driving shaft to cause the level driving gears to be rotated along the sector gears to dispose a chair or carry platform on the connecting frame to a level position and the two driven gears installed on the output shaft of the driving gear box are caused to be rotated reversely with the driving shaft and moved forward or backward along the racks to cause the moving and driving mechanism to move simultaneously along the guiding rails or guiding grooves to a balance position.
