An electric self-balancing vehicle including a top cover, a bottom cover, an inner cover, a rotating mechanism, two wheels, two hub motors, a plurality of sensors, a power supply, and a controller is described herein. The top cover includes a first top cover and a second top cover disposed symmetrically and rotatable relative to each other. The bottom cover is fixed to the top cover and includes a first bottom cover and a second bottom cover disposed symmetrically and rotatable relative to each other. The inner cover is fixed between the top cover and the bottom cover and includes a first inner cover and a second inner cover disposed symmetrically and rotatable relative to each other. The rotating mechanism is fixed between the first inner cover and the second inner cover. The two wheels are rotatably fixed at two sides of the inner cover, respectively. The two hub motors are fixed in the two wheels, respectively. The plurality of sensors is disposed between the bottom cover and the inner cover, respectively. The power supply is fixed between the first bottom cover and the first inner cover. The controller is fixed between the second bottom cover and the second inner cover, the controller is electrically connected with the plurality of sensors, the power supply, and the hub motors, and the controller controls the hub motors to drive the corresponding wheels to rotate according to sensing signals transmitted by the sensors.

A mobility scooter conversion kit and method that utilizes a standard mobility scooter as its base frame to make the scooter resemble any motor vehicle. The main frame of the scooter is only altered by adding an extension member with a bracket, replacing a first bolt on the seat frame with a long bolt, and reversing the orientation of a second bolt on the opposite side of the seat frame. The first body member that resembles the front of a motor vehicle has a recess that sits on the steering column of the scooter and is secured into place with a latching mechanism. The second body member that resembles the rear end of a motor vehicle is hooked on to the bracket of the extension member and secured into place using the long bolt and a bolt attachment connecting to the reversed bolt.

Steering and roll control systems to counteract yaw and/or roll forces during operation of a vehicle having first and second wheeled members coupled together by an articulating joint mechanism that is configured to pivot in a yaw direction and/or a roll direction. The steering assistance systems include a biasing unit configured to apply a counteracting force to bias the first and second wheeled members toward a straight-line arrangement thereof. The roll control systems include an additional biasing unit configured to apply a counteracting force to bias the first and second wheeled members toward a level alignment arrangement of the vehicle.

A rugged and compact articulated wheel with at least two hubs, and wheeled vehicles that include one or more of such articulated wheels.

A rugged and compact articulated wheel with at least two hubs, and wheeled vehicles that include one or more of such articulated wheels.

A scooter is provided. The scooter may include a front wheel assembly, a pair of connector elements, and a pair of rear wheel caster assemblies. The pair of connector elements may be cooperable with the front wheel assembly for lateral movement relative thereto. Each of the pair of rear wheel caster assemblies may be secured to a rear portion of one of the connector elements and may have a caster defining a caster axis and a rear wheel mounted for rotation to the caster. The front wheel assembly and connector elements may be arranged with one another such that adjustment of a height of a front portion of each of the connector elements adjusts an angle of the respective caster axis relative to an underlying surface. The scooter may include a lock mechanism to selectively engage the connector elements and to facilitate transition between multiple types of scooter movement.

In an inverted pendulum vehicle (10) including a vehicle body frame (12) fitted with a saddle (32) at an upper end thereof; a main wheel (40) combining a plurality of free rollers (44) arranged along a circle such that rotational center lines of the free rollers are each directed along a tangential line of the circle, a pair of drive disks (50) each carrying a plurality of free rollers (52) arranged along a circumferential direction and configured to engage the free rollers of the main wheel, and a pair of drive units (72, 86) including a pair of electric motors (68, 82) for individually driving the drive disks under an inverted pendulum control, the two drive units are positioned one behind the other between the saddle and a rotational center line of the main wheel.

Provided is an inverted pendulum vehicle including a display unit for providing a guide on an operation for putting the vehicle body into the tilted position from the upright position or into the upright position from the tilted position according to a state of the vehicle. In particular, the display unit indicates a direction in which the vehicle body is required to be moved when placing the vehicle body from the tilted position to the upright position and from the upright position to the tilted position.
