Abstract
Autonomous and lightweight vehicle intended to transport a city dweller combined with the use of public transportation. Formed by one motorized wheel on which the user maintains, through speed, his or her lateral balance, and longitudinal balance is ensured by automatic functioning driven by an accelerometer. The footrests and the guide supports that tightly hold the leg are retractable. Driving does not require the use of the hands. The entire device goes into a bag, e.g. a backpack, and weighs less than 4 kg.
Claims3
Autonomous electric mobile aid intended to transport a city dweller comprising:
- a single wheel, an electric motor, a battery, a fork, and two footrests characterized in that the ergonomics and driving of it are intuitive and do not require the use of the hands by means of:
- two combined supports secured to the fork on either side of the wheel that are each configured to operate as a lever to convey stress and torque of the wheel response to a leg of the user;
- the motor being of the type that keeps the wheel directly under the center of gravity of the average city dweller;
- a driving electronics of the motor controlled linearly by a balance sensor on the fork;
- wherein lateral steering is agile by means of the single wheel having a tread that is approximately round in shape in a plane parallel to an axis of rotation of the single wheel;
- and
- wherein it is compact when carried by the city dweller by means of the two footrests being foldable.
