The present invention discloses an assembly and method for power generation. The assembly comprises a first rotatable member (100), a second rotatable member (200) driven to move by the first rotatable member (100) at which the second rotatable member (200) is in contact with, a third rotatable member (300) driven to move about a rotating axis by the second rotatable member (200) thereof, a rotatable disk (400) mounted to the third rotatable member (300) driven to move correspondingly about the said rotating axis by the third rotatable member (300) thereof, and an electromechanical energy converter (500) having a rotatable unit (501) coupled to the rotatable disk (400) configured for generating electrical energy.

The disclosure is directed to an apparatus for generating energy in response to a vehicle wheel rotation. The apparatus may include a first roller comprising a curved roller surface configured to be positioned in substantial physical contact with a first wheel of the vehicle. The first roller may be configured to rotate in response to a rotation of the first wheel. The apparatus may further include a first shaft rotatably couplable to the first roller such that rotation of the first roller causes the first shaft to rotate. The apparatus may further include a first generator operably coupled to the first shaft. The generator may be configured to generate an electrical output based on the rotation of the first shaft and convey the electrical output to an energy storage device or to a motor of the vehicle that converts electrical energy to mechanical energy to rotate one or more wheels of the vehicle.

Provided is a wheel bearing apparatus with a generator that can have a simplified structure to reduce costs and is capable of preventing electrolytic corrosion. The wheel bearing apparatus with a generator includes a wheel bearing and a generator. The generator includes a stator attached to a fixed wheel and a motor rotor attached to a rotating wheel and is of an outer-rotor type in which the stator is located on an outer periphery of the wheel bearing, and the motor rotor is located radially outside of the stator. The wheel bearing apparatus with the generator further includes at least one conducting unit that conducts a current between the fixed wheel and the rotating wheel.

A portable energy-saving and environment-friendly electric vehicle is light in weight, small in volume, convenient in electricity charging, and can be disassembled for portability in a backpack. The backpack is further furnished with a crank-handle generator to enable manpower electricity generation and working out simultaneously. This energy-saving and environment-friendly electric vehicle is mainly comprised of two adjustable skateboards and a support rod for adjusting speed and connecting a battery set. The battery set can be conveniently replaced roadside or at other locations. In a situation of power loss, manpower can be used to charge the battery set. Thus, the situation of power loss fully disabling the electric vehicle can be met. In addition, the battery set associated with the generator is reliable for charging mobile phones and computers.

The present invention relates to a motorized hub assembly for a bicycle wheel. The assembly has a hub shaft extending along a longitudinal axis with a cavity to receive a quick release axle. A bearing having a radially inner ring is arranged radially outside the hub shaft. A hub body is rotatably mounted on the hub shaft about the longitudinal axis and an electric motor is arranged inside the hub body. A routing opening for passage of electrical conductors for the electric motor pass through a routing opening arranged radially between the inner ring of the bearing and the hub shaft.

The present utility model belongs to the technical field of electric control, in particular to a device for remotely driving and controlling an electromechanical mechanism based on a hand driver. In this solution, a hand driver, a motor unit and a power supply generated by the driver are used to remotely control the electromechanical mechanism to work in real time. Through each functional module, the motor in the remote motor unit can be controlled to rotate as long as the hand driver is cranked, thus driving the electromechanical mechanism or all devices driven by the motor; the crank of the driver can rotate the driver by hand or by foot; power is generated by the remote hand driver and supplied to the motor of the driven device; the rotation of the motor drives the electromechanical mechanism or the door to move; a movable part of the driven device is equipped with a gravity sensor connected with the driven motor, and when the electromechanical mechanism or the door clamps a creature, the gravity sensor will cut off the external power supply of the motor, stop the motor and stop the device from working, so as to protect the creature and allow it to have time to escape from the danger zone.
