Abstract
A moving vehicle according to the present disclosure includes a chair frame including universal casters, a sitting seat disposed above the chair frame and connected to the chair frame, and a driving unit disposed below the sitting seat and connected to the chair frame so that the driving unit can rotate about a unit connection shaft, in which the driving unit includes a driving wheel including a rotation shaft located at a position deviated from a central axis of the unit connection shaft, a velocity detection unit configured to detect a rotational velocity of the driving wheel, and a driving control unit configured to control a velocity of the driving wheel according to an external driving force applied to the driving wheel.
Claims6
A moving vehicle comprising:
- a chair frame comprising universal casters;
- a sitting seat disposed above the chair frame and connected to the chair frame;
- and
- a driving unit disposed below the sitting seat and connected to the chair frame so that the driving unit can rotate about a unit connection shaft, wherein
- the driving unit comprises:
- a driving wheel comprising a rotation shaft located at a position deviated from a central axis of the unit connection shaft;
- a velocity detection unit configured to detect a rotational velocity of the driving wheel;
- and
- a driving control unit configured to control a velocity of the driving wheel according to an external driving force applied to the driving wheel, wherein
- the driving control unit does not supply power to the driving wheel in a period during which a velocity of the moving vehicle is equal to or lower than a first velocity, and
- the driving control unit supplies power for moving the moving vehicle at the first velocity to the driving wheel when the velocity of the moving vehicle becomes a velocity that is higher than the first velocity and is equal to or lower than a second velocity higher than the first velocity.
A moving vehicle comprising:
- a chair frame comprising universal casters;
- a sitting seat disposed above the chair frame and connected to the chair frame;
- and
- a driving unit disposed below the sitting seat and connected to the chair frame so that the driving unit can rotate about a unit connection shaft, wherein
- the driving unit comprises:
- a driving wheel comprising a rotation shaft located at a position deviated from a central axis of the unit connection shaft;
- a velocity detection unit configured to detect a rotational velocity of the driving wheel;
- and
- a driving control unit configured to control a velocity of the driving wheel according to an external driving force applied to the driving wheel,
- wherein the driving control unit stops supplying power to the driving wheel when a time during which a torque larger than a predefined limit torque is applied to the driving wheel by an external driving force continues for a predefined limit time or longer.
