An electric vehicle includes a front frame (1), a rear frame (2), and a sliding seat (3). The front frame has a first gear set (14). A movable rotation shaft (15) connects the front frame and the rear frame. The rear frame has a track (21). A sliding support (22) is mounted on the track and connects a linear driver (23) which connects a connecting member (25) which connects a connecting shaft (26) which connects the front frame. A wheel support (27) connects the rear frame and an auxiliary wheel (28) and has a second gear set (29) meshing with the first gear set. A linkage (4) connects the rear frame and support rack (31). A link unit (41) connects the linkage and the sliding support.

The sliding seat is mounted on a seat support (33) which is mounted on the support rack.

A compact electric transport device that is convertible between a stowed configuration and a riding configuration is described. In one embodiment, a foldable steering assembly for an electric transport device includes a steering column disposed within an opening along a top surface of the electric transport device. The steering column has a horizontal orientation that extends along a length of the electric transport device within the opening in a folded position. The foldable steering assembly also includes a steering shaft connected to an axle of a wheel of the electric transport device. The foldable steering assembly further includes a hinge connecting the steering column to the steering shaft. The steering column is configured to transition to a vertical orientation that is perpendicular to the opening along the top surface of the electric transport device in an extended position.

Disclosed is a foot-operated private vehicle, the vehicle including a chassis that extends heightwise along a vertical axis, the vehicle also including a front set of wheels mounted at the front of this chassis, a rear set of wheels mounted at the rear of this chassis, and a unit for controlling the speed and direction of the vehicle, taking the form of a right-hand pedal and a left-hand pedal, the private vehicle being characterized in that at least one pedal, known as the steering pedal, is mounted in a rotatable manner with respect to the chassis about a pivot axis parallel to the vertical axis of the chassis of the vehicle, a rotation of this steering pedal about its pivot axis being used to control the direction of the vehicle.

A vehicle body frame includes a lower frame fixed to a floor of a vehicle to define a lower region of an internal space in the vehicle, a roof frame connected to an upper portion of the lower frame to define an upper region of the internal space, configured to slid in a vertical direction of the vehicle with respect to the lower frame, to expand the internal space upwards when the roof frame slides upwards, a lower door frame forming a lower portion of a vehicle door, and an upper door frame connected to the lower door frame to form an upper portion of the vehicle door, and configured to slid together with the roof frame to expand the vehicle door upwards when the roof frame slides upwards.

The present disclosure provides a hands-free, self-balancing vehicle including a tiltable platform for a rider to stand on. The tiltable platform may tilt in any direction and direct the direction of motion of the vehicle. The vehicle is compact and may be disassembled for easy portability.

A foldable vehicle may include a chassis comprising a static support, a dynamic chassis frame that includes at least two substantially opposite frame parts and a folding mechanism for decreasing or increasing a distance between the at least two substantially opposite frame parts across a lateral axis of the vehicle between a folded state and an unfolded state; and a controller to control the folding mechanism.

A vehicle according to the present disclosure is a vehicle body in which at least a power portion on which a power source of a vehicle body is mounted and a front-rear portion to which at least one of a front wheel and a rear wheel is attached are connected via a link mechanism. The vehicle reversibly changes shape to a traveling form in which the power portion and the front-rear portion can travel while maintaining a flat state by sliding the fastening portion along the guide hole, and a transportation form in which the front-rear portion can be transported while maintaining a state in which the front-rear portion is bent toward the power portion with a fold line between the front-rear portion and the power portion.
