Provided is a moving body. A control device of the moving body starts a first control processing that moves a movement part so that a posture of a base with respect to a passenger seat becomes a predetermined posture with an auxiliary grounding part lowered and grounded. The control device starts a second control processing that lifts the auxiliary grounding part with respect to the base and a third control processing that moves the movement part 2 so as to stabilize a posture of the passenger seat after a delay from the start of the first control processing.

Drive disks are configured to rotate a main wheel by applying a frictional force thereto. Each of the drive disks includes a base and a plurality of rollers. The base includes a first sheet metal member and a second sheet metal member. The first sheet metal member includes a first central part and a plurality of first arm parts. The second sheet metal member includes a second central part and a plurality of second arm parts. Each of the rollers has a first end and a second end. Each of the first arm parts includes a first supporting part and a second supporting part. Each of the second arm parts includes a third supporting part and a fourth supporting part. The first supporting part and the second supporting part are inclined to each other. The third supporting part and the fourth supporting part are inclined to each other.

A single-wheeled balance vehicle comprises a motor, pedals, a wheel, a power module and a control module. The motor comprises a motor housing and a spindle. The power module and the control module are fixed to the spindle. The power module comprises at least one power unit. The control module comprises a first control unit electrically connected to the power unit and the motor. The two ends of the spindle are fixedly connected to the pedals respectively. The wheel is of a hollow structure having two ends formed with openings, is arranged on the motor housing in a sleeving manner and is fixedly connected to the motor housing. The power module and the control module are located in the wheel. Miniaturization of the single-wheeled balance vehicle is facilitated, and the service life of the single-wheeled balance vehicle is prolonged.

A nose-dive prevention device for a one-wheeled motorized transportation device is disclosed, which has wheels that strike the ground in the event of a nose-dive situation, instead of the bumper, which could otherwise become abruptly hung and thus throw the rider. The nose-dive prevention device has a base for attachment to the front of the one-wheeled motorized transportation device, and one or more wheels connected to and extending from the base. The wheels are positioned to interpose between the front end of the one-wheeled motorized transportation device and the ground and contact the ground when the front end exceeds a nose-dive angle. However, under normal riding conditions, the wheels are spaced above the ground at a height sufficient to allow normal angular variability of the riding platform needed for control of the one-wheeled motorized device.

The present invention discloses a type of secure and efficient wheel assembly using fluid or solid stuffing materials so as to minimize the blowout risks, a wheel rim transmission assembly, an energy exchanging arrangement used in transporting system, and a vehicle energy storage system, as well as corresponding methods for manufacturing and preparing such assemblies and arrangements in applications.

The present invention relates to an upright single-wheeled electromotive apparatus, the upright single-wheeled electromotive apparatus according to an embodiment of the present invention comprising: a handle part having a speed-controlling means on one side; an upper frame connected to the handle part and extending lengthwise, and accommodating a battery therein; a brake connected to the upper frame; a drive unit connected to the brake, and rotates a roller; a pair of lower frames for supporting the upper frame while fixing the brake and drive unit on the inner side thereof; a wheel, positioned between the pair of lower frames, which, when the upper frame moves in one direction with respect to a reference position, stops rotating due to the brake coming into contact with the outer surface of the wheel, and when the upper frame moves in the other direction with respect to the reference position, rotates due to the roller of the drive unit coming into contact with the outer surface of the wheel; and a control unit for varying the rotational speed of the drive unit by means of the speed-controlling means.
