Abstract: A self balancing scooter steered with thighs is provided, which includes: two wheels having motors mounted; a motor housing for mounting the motors therein so as to allow rotary shafts of the motors to be located linearly; a footrest disposed on top of the motor housing; an erecting housing located on top of the footrest and having a battery and a controller mounted, the controller being adapted to control driving and direction change of the self balancing scooter, a cover disposed on top thereof, and an insertion hole formed on the center of the cover; a saddle having a seatpost fitted to the insertion hole of the cover; and a thigh steering plate mounted just on the underside of the saddle through the seatpost so as to be turned in left and right sides through the thighs of the rider sitting on the saddle to perform the direction change.

Abstract: A backpack type self balancing scooter having a foot-driven steering apparatus mounted thereon is provided, including: two wheels having motors mounted thereon; a motor housing for mounting the motors therein in such a manner as to allow rotary shafts of the motors to be located linearly to each other; a footrest; a shuttle ring mounted on any one side of the footrest; an erecting housing, a controller mounted on the upper portion, a cover disposed coveringly on top thereof, and an insertion hole formed on the center of the cover; a saddle; and a backpack. The rider walks in the state of carrying the backpack on the back, or puts the backpack on the around, sits on the saddle to drive the self balancing scooter in the state where both hands are free, while conducting the direction changes through the shuttle ring turned with his or her foot.

Abstract: Disclosed is a method for driving a two-wheel self-balancing scooter to maintain straight drivability at occurrence of external force. The method includes a driving ready step of applying a power to the two-wheel self-balancing scooter (S10), a driving step of setting a driving speed and a forward/backward direction by leaning an occupant's body forward or backward (S20), when one wheel goes flat, a revolutions increasing step of rapidly increasing revolutions of the flat wheel (S30), a revolutions decreasing step of decreasing revolutions of a normal wheel according to the revolutions of the flat wheel (S40), a revolutions synchronizing step of equally setting the revolutions of the flat wheel and the normal wheel (S50), and a synchronization repeating step of repeating the revolutions synchronizing step (S60).

Abstract: An electric vehicle including: an operating shaft inserted into the center of the upper portion of a motor housing and having steering handles mounted on the front end thereof to change the drive direction of the vehicle; motors mounted onto the interiors of both sides of the motor housing and having front wheels coupled correspondingly thereto; a foot board mounted on the rear side of the operating shaft; a battery and a controller mounted on the underside of the foot board; a rear connection member protruded backwardly from the board and having a caster mounted on the underside thereof; and a front connection member protruded forwardly from the foot board, coupled by a connection shaft to foot board shaft holes formed on the lower ends of both sides of the motor housing, in a state of being isolated downwardly.

Abstract: The present invention relates to a backpack type bag with a self-balancing electric vehicle mounted thereon that includes: two wheels each having a motor mounted thereon; a foot board mounted on the top surface of each motor; a support rod fixed on the foot boards; a housing disposed on one side of the support rod for accommodating batteries and a controller thereinto; a handle mounted on the top portion of the support rod in such a manner as to be inserted and drawn into/from the support rod; and a bag adapted to encompass the support rod and the housing, whereby the bag into which a user's items are put is carried on the user's shoulders, and in a state where the bag is placed above the wheels, the user rides the self-balancing electric vehicle after his feet place on the foot boards.
