摘要： Various hub motor arrangements, systems, and methods are disclosed. The hub motor arrangement may include a transmission assembly to provide increased torque. The transmission assembly may include a motor gear, a planetary gear, an idler gear, and a ring gear. The idler gear may be positioned farther away from an axis of rotation of the hub motor arrangement compared to the planetary gear. The motor gear may drive the planetary gear, the planetary gear may drive the idler gear, and idler gear may drive the ring gear. The rotation of the ring gear may rotate a housing of the hub motor arrangement to propel a vehicle incorporating the hub motor arrangement.

摘要： An autonomous electronic bicycle comprises a frame, a front wheel that can be powered by a first electronic motor, a rear wheel that can be powered by a second electronic motor, and handlebars that can steer the front wheel which can be controlled by a third electronic motor. The autonomous electronic bicycle can operate autonomously, traveling to a chosen destination. When operating autonomously the autonomous electronic bicycle can shift between a set of balance modes, including a mode used when moving and a mode used when stationary but balanced. To transition between modes, a transition sequence of control commands can be selected and used.

摘要： Motor control systems and methods for micromobility transit vehicles are provided. A micromobility transit vehicle may include an electric motor configured to drive a rotation of a wheel. The electric motor may include a plurality of windings and a plurality of switching circuits. The switching circuits may be configured to selectively direct current from a power supply through the windings to generate a torque by the electric motor to drive the rotation of the wheel in response to associated control signals. The switching circuits may be configured to passively bypass the windings in response to an interruption of the control signals. Depletion of the power supply may result in the interruption of the control signals.

摘要： The embodiments include a primary frame (10) supported by two wheels (50), and connected to a towing vehicle via a tow bar (18). A cylindrical brush assembly (1) is mounted on a secondary frame (12), which rotates around the primary frame. The brush rotation is driven by an electric motor (110, 220) attached to the secondary frame. The brush rotation goes counter to the wheels' rotation. The amount of pressure between the brush and the ground is controlled by the length of a spring (23) that links the two frames. In one embodiment, the brush axis forms an angle (280) with the wheels' rotation axis, and the debris gets pushed to the side as the sweeper moves forward. In another embodiment, the brush axis is parallel to the wheels' rotation axis and the debris is driven around the brush by a wrap-around guide (100), into a hopper (140).

摘要： A method for controlling a derailleur in low battery remaining capacity includes determining whether a remaining capacity of a first battery of the derailleur is smaller than or equal to a first derailleur battery threshold. When the remaining capacity of the first battery is determined to be smaller than or equal to the first derailleur battery threshold, at least one of gear positions of the derailleur is invalided and non-selectable by the derailleur.

摘要： An electric snowmobile that can reduce a load locally applied to a body frame is provided. The electric snowmobile includes a body frame, a right ski and a left ski, a track mechanism, a steering shaft, an electric motor, and a battery. The body frame includes a shaft support frame that rotatably supports the steering shaft, a front frame that extends forwardly and downwardly from the shaft support frame, and a rear frame that extends rearwardly and downwardly from the shaft support frame. The battery is supported by the front frame and the rear frame such that at least a portion of the battery is disposed in a region formed by a line connecting the front frame, the rear frame, a lower end of the front frame, and a lower end of the rear frame in a side view.

摘要： Provided are a self-balancing scooter and a control method thereof, and a kart powered by the same. The self-balancing scooter includes two scooter bodies on which foot boards and motorized wheels are disposed, and a rotating shaft device, where the rotating shaft device includes a rotating shaft, two axle seats, and a torsion limiting mechanism. The torsion limiting mechanism controls a rotation angle by the fit between a limiting portion on the rotating shaft and a fitting portion on one axle seat. The present disclosure realizes torsion limit by directly using the rotating shaft and the axle seats without the use of an additional element (for example, a limiting shaft), thus simplifying the structure of the rotating shaft device and facilitating assembly.
