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 disclosure provides a method and an apparatus for processing a motor control signal, an electric vehicle, a storage medium and an electronic apparatus. The method may include: a predetermined operation is detected, wherein the predetermined operation includes that a rider leaves an electric vehicle; and a motor control signal which is input via a speed control component of the electric vehicle is shielded. Through the present disclosure, the problem that the rider of the electric vehicle forgets to press a P gear or fails to activate the P gear successfully to cause the false operation of the speed control component and thus cause a harm to the electric vehicle or a user or a surrounding environment in the related art is solved; and therefore, the vehicle is prevented from being uncontrollable, and the safety of the electric vehicle or the user or the surrounding environment is guaranteed.

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 system includes a first wheel connected to a left vehicle body comprising a first upper case and a first lower case, a second wheel connected to a right vehicle body comprising a second upper case and a second lower case, a rotating connection member between the left vehicle body and the right vehicle body, a plurality of batteries placed inside the rotating connection member, and a controller on at least one of the first upper case and the second upper case.

A method for laterally stabilizing a single-tracked motor vehicle, driven with the aid of an electric motor, that is in a vertically aligned state and at a standstill. The front wheel of the motor vehicle has a steering angle in which the electric motor is controlled in such a way that it exerts drive torques on the motor vehicle that act in alternation in the forward direction and in the reverse direction.

Powered wheel assemblies and methods of manufacturing and operating such assemblies are provided.

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.

An in-wheel motor includes a housing 32 that is supported by two support portions 14A and 14B on a rotation axis in an inner space of a wheel and includes a heat dissipation surface at at least one end portion thereof in a rotation axis direction, and a stator core 62 that is supported between the two support portions 14A and 14B and inside the housing 32 and has an inner peripheral surface to which a distance from the rotation axis is smaller than a distance from the rotation axis to an outer edge of the heat dissipation surface.
