A foldable structure of an electric vehicle is disclosed. In the foldable structure, a frame defines a stowing space, and includes a connection base and a rotatable seat. The connection base has a chute and the seat includes a link rod. The wheel part includes two wheel casings, a tire and a driving device, and a containing space is formed between the wheel casings for containing the tire and the driving device. The wheel casings has a rotator cap protruded at tops thereof, and the rotator cap has an axle hole longitudinally cut therethrough, and the rotator cap is pivotally connected with the rotatable seat by the axle hole, whereby the link rod can be slid into the chute, and the two wheel casings and the tire can be laterally rotated into the stowing space, such that the electric vehicle can just occupy smaller space.

A two-wheel, self-balancing vehicle is disclosed. In one aspect, the two-wheel, self-balancing vehicle comprises a first wheel and a second wheel, the first wheel and the second wheel being spaced apart and substantially parallel to one another. The two-wheel, self-balancing vehicle further comprises a foot placement section connecting the first wheel and the second wheel. The two-wheel, self-balancing vehicle further comprises a set of position sensors in the foot placement section, the set of position sensors configured to generate inclination angle signals and velocity signals of the two-wheel, self-balancing vehicle. The two-wheel, self-balancing vehicle further comprises a first gravity sensor and a second gravity sensor in the foot placement section, the first gravity sensor and the second gravity sensor configured to generate weight signals and gravity angle signals. In addition, the two-wheel, self-balancing vehicle comprises a control logic configured to output control signals that control the movement of the two-wheel, self-balancing vehicle in response to the inclination angle signals, the velocity signals, the weight signals, and the gravity angle signals.

The present invention relates to a human-propellable vehicle comprising a chassis and a footplate for receiving a rider's feet. The footplate is movably mounted to the chassis so that at least part of the footplate can be deflected up towards the rider in the event of a collision between the underside of the footplate and an object or terrain passing under the chassis.

A water shield structure for a transportation device and the transportation device having such a water shield structure. The transportation device is preferably a self-balancing device and may include a friction drive motor. The water shield structure helps reduce the entry of moisture from a riding surface into the wheel envelope or drive mechanism of the device. The water shield structure may extend laterally from a wheel and be enclosed, at least in part, in a housing.

An electric scooter is disclosed that includes a concaved-shaped center frame comprising a first and second curved members, a concaved-shaped rear frame hingebly attached to the center frame about a first axis, a front frame portion hingeably attached to the center frame about a second axis perpendicular to the first axis, and support cables coupled at a first end to the front frame portion and at a second end to the rear frame.

A self-balancing powered unicycle device (100) having a single hubless wheel is disclosed. The self-balancing powered unicycle device comprises: a single wheel (120); a motor adapted to drive the wheel; a balance control system adapted to maintain fore-aft balance of the unicycle device; at least one foot platform (165) for supporting a user of the unicycle device; and a casing (110) adapted to cover at least a portion of the outer rim of the wheel. The self-balancing powered unicycle device further comprises at least one energy storage device compartment (150A, 150B) protruding outward from a side of the casing (110) and adapted to house an energy storage device for powering the unicycle device.

A tiltable electric tricycle as in the present invention comprises: (a) a frame, (b) a front fork mounted to the frame, (c) a front wheel with hub motor mounted to the front fork, (d) a seat, (e) a steering handle bar, (f) a pair of laterally spaced rear wheels on a common axle, (g) a support base with two quick release clamps for securing the axle of the rear wheels and the base has a shaft tube fitted into the bottom tube of the frame to connect to the frame rotatably, (h) a pair of footrests, (i) a battery to power the hub motor; furthermore the bottom tube points to the ground contact point of the front wheel; furthermore the frame has a horizontal oriented metal plate at the rear end of the bottom tube positioned above the support base of the rear wheels; and when the frame is tilted relative to the rear wheel support base to a certain extent, an end of the metal plate touches the rear wheel support base and thereby restricts the extent the frame can tilt; furthermore the axle of the rear wheels is secured to its support base using two quick release clamps and can be released quickly from the quick lease clamps so that the axle with two rear wheels can be separated from the rest of the tricycle for easy transportation; furthermore the two footrests are rotatably connected to the base and can swing toward the rear of the tricycle to reduce the width of the tricycle. In operation, the rider of the tricycle seats on the seat with two feet stepping on the footrests of the rear frame to keep balance and can tilt the front part of the tricycle around the axis line to maintain balance in response to road condition, speed, or turning while the rear part with two rear wheels remain stable.

Disclosed is a single-wheeled balance vehicle. The single-wheeled balance vehicle includes: a wheel provided on a wheel frame, a motor transmission mechanism fixed in the wheel frame and arranged to drive the vehicle according to acquired manned mode information; a wheel cover arranged to partially cover the wheel; a skeleton arranged to reinforce mechanical strength of the wheel cover; and footboards arranged to be stepped on by both feet of a driver in driving. The wheel cover partially covers the wheel and in embodiments may be in a surface contact, so that the contact area is larger, contact stress is more dispersive, a strain is relatively small, the deformation of the wheel cover can be reduced, the possibility that a tire or a hub motor is rubbed or locked due to deformation of the wheel cover in the related art can be avoided, and safety performance can be improved.
