BALANCED MOBILITY DEVICE FOR DISABLED INDIVIDUALS

WIPO Patent Application WO/2019/218288

A1

A balanced mobility device for disabled individuals, consisting mainly of four controllable rotating composite wheels (15) and a vertical vehicle body balancing frame. The composite wheels (15) comprise a traveling wheel (16), a belt (18), and a Mecanum wheel (17). The traveling wheel (16) is used for an ordinary road. A combination of the traveling wheel (16) and the belt (18) is used for an uneven road. A combination of the Mecanum wheel (17) and the belt (18) is used for stairs. The vehicle body frame maintains the balance of a vehicle body in a vertical direction by using a principle based on the varied interior angles of a parallelogram. The mobility device can be operated independently, and a suitable wheel combination of the composite wheels (15) and a corresponding inclination angle can be selected according to road conditions prior to travel. During travel, the mobility device is capable of maintaining balance automatically, and performing automatic adjustments based on the unevenness of a road, thereby ensuring stable and smooth travel; especially when climbing stairs. The invention is simple to operate, enables a quick direction change while climbing stairs, and accordingly achieves continuous, stable, and rapid stair climbing.
