Smart Control Systems for Electric Skateboards

Electric skateboard that improves convenience and safety by measuring the angle of the user's foot and controlling the speed based on that angle. The skateboard has a rotatable footrest at the rear end. The skateboard's speed is adjusted by controlling the electric motor based on the rotation angle of the footrest. This allows the user to accelerate/decelerate by rotating their foot on the footrest instead of using a separate remote control.

A universal full-wire controlled skateboard chassis system for electric vehicles that enables faster development of new vehicle models by integrating power, braking, steering, and thermal management onto the chassis. This provides an independent power system that decouples the upper and lower bodies. The chassis has a skateboard shape with integrated components like in-wheel motors, CTC batteries, steering motors, and braking systems. It uses full-wire distributed control to enable independent steering, braking, and driving of each wheel. This lowers the center of gravity for better performance and reduces development costs by providing a common chassis.

Upgrading kit to convert a dual-wheel drive electric skateboard into a four-wheel drive skateboard. The kit has a front-drive transmission assembly with motors, wheels, and synchronous belts that can be added to the front of the skateboard. The assembly replaces the original front wheels and connects to the skateboard's electronics. This allows switching between dual and four-wheel drive modes by installing or removing the front drive kit.

Electric skateboard with foot-controlled acceleration/deceleration instead of a handheld remote. The skateboard has a middle control system and foot sensors at one end. The foot sensors detect pressure differences between the front and rear ends of the skateboard. This pressure variation is used to accelerate or decelerate the skateboard without the need for a handheld remote. The foot sensors can be buttons, photoelectric sensors, or pressure sensors.

Electric skateboard with customizable setup for versatility on different terrains. The skateboard has adjustable motor positions on the rear truck to change the wheelbase and wheel clearance for off-road versus street riding. The motors, electronics, and battery are integrated into the deck for a streamlined design. This allows converting the skateboard between a street setup with shorter wheelbase and clearance, and an all-terrain setup with longer wheelbase and clearance. The user can easily swap the wheels between street and all-terrain types to complete the conversion.

A management system for electric skateboards that improves safety and efficiency. The system uses proportional controllers to smoothly accelerate and decelerate the skateboard without jolts or jerks. It also has features like regenerative braking, cell balancing, and power saving to optimize battery usage. The controllers use gains that adjust based on speed difference to provide proportional control. The skateboard can transition between normal, power saving, and cutoff modes based on battery level. The cell balancing prevents imbalances during charging. The regenerative braking recovers energy and prevents jerks.

A convertible electric scooter that can transform between an electric skateboard and a handheld scooter. The scooter has a removable handlebar that can be raised and locked in place to convert the scooter into a skateboard. The handlebar attaches to the front of the scooter body via a rotating shaft mechanism. This allows the user to switch between the skateboard and scooter modes by lifting the handlebar up. The scooter also has features like gravity sensing pedals, remote control, and a removable battery for portability.

Electric skateboard with improved turning performance and reduced safety risks compared to traditional skateboards. The skateboard has a transmission system with multiple gears to allow steering without tilting the deck. A motor, reduction gear, planetary gears, and side gears transfer power to the wheels. The driven wheels rotate independently from the front wheels. This allows turning by selectively braking the inner wheels instead of tilting the board. This provides more controlled steering and reduces the risk of board wobble or falls during turns.

Self-balancing skateboard with improved balance and maneuverability compared to traditional single-wheel boards. The skateboard has two parallel wheels on each side of the chassis instead of a single center wheel. This provides four contact points with the ground for better stability and allows the rider to control left/right balance separately from forward/backward balance. An elastic reset device keeps the pedals parallel to the chassis when not in use. An angle sensor detects pedal rotation. A controller uses this data to balance the skateboard and enable features like hovering in place and turning without moving forward.
