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 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 one-wheel electric skateboard that enables stable and safe riding on any terrain without the need for the rider to tilt or apply force to the board for propulsion. The board has a controller with sensors to accurately control forward/backward movement, turning, and speed using the controller's up/down/left/right angles instead of tilting the board. This allows comfortable and stable riding without balancing issues. The controller also has modes like cruise and turbo for acceleration and deceleration. The board has a foldable design, wheel cover, and brake pads for added safety. It uses wireless communication with error detection to prevent data loss.

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.

Gravity-sensing electric skateboard that allows control using foot pressure instead of a remote. The skateboard has a fixed board connected to a support plate with front wheels. A movable board connected to a second support plate with rear wheels. When rider steps on both boards, it compresses a block that pushes a connecting rod to move a switch and start the motor. Removing feet restores springs to push the rod back, turning off the switch and stopping the skateboard.

An adjustable electric skateboard that allows customizable length and eliminates the need for a separate handle. The skateboard has telescoping pedals that can extend or retract to adjust the overall length. The rear wheel mechanism is attached to the bottom plate that articulates with the rear pedal. Motors drive the rear wheels. A sensor detects pedal-plate distance changes. The pedals can rotate axially forward to extend length or backward to retract.

Skateboard with improved turning radius and stability using tilt control. The skateboard has at least one universal wheel and two driving wheels. A gyroscope senses platform tilt and generates a drive signal to control the speeds of the driving wheels differently to turn the board. This compensates for the large turning radius of existing rodless electric skateboards. The universal wheel follows the platform tilt. A controller receives tilt data, generates the drive signal, and coordinates with the pedal buttons. The skateboard can also compensate for slope using pressure sensors. Telescopic pedals adjust size for different riders.

Small electric skateboard with active suspension for improved stability and ride quality. The skateboard has an elongated platform with coaxial wheels on each end. Each wheel has an independent suspension with an electromagnetic shock absorber instead of a traditional spring. This allows active adjustment and tuning of the suspension for better ride comfort and stability compared to passive spring suspensions. The electromagnetic shock absorbers can also be controlled to provide additional damping or stiffness as needed. This improves the skateboard's ability to handle rough terrain and bumps. The active suspension also enables automatic balancing and stability without needing the rider to actively lean like on traditional self-balancing skateboards.

An electric skateboard with improved safety, compact size, and motion control capabilities. The skateboard has features like sensors, electromagnetic brakes, an embedded motor, and a compact design to enhance safety, portability, and maneuverability. The sensors detect obstacles at the front. The electromagnetic brakes provide braking force. The embedded motor and battery inside the deck eliminate external components. The compact design with integrated components reduces size and weight for easier carrying.

An auxiliary electric skateboard that allows different user groups to control the board based on their skill level. The skateboard has a main deck with oblique ends to reduce air resistance. Inside the deck is a compartment containing a rechargeable battery and sensing module. The battery uses fast charging and has a warning light. The skateboard also has a sandpaper layer on the top to prevent slipping. This auxiliary electric skateboard provides three control modes: full electric mode, manual mode with electric assistance, and manual mode without electric assistance. A user can choose the mode based on their skateboarding experience.

Electric skateboard with weight-based speed control that increases safety by automatically adjusting speed based on rider weight. The board has weight sensors at the front to measure rider weight. If the weight exceeds a predetermined reference value, the control unit increases the rear wheel speed. This prevents oversteering and provides stability for heavier riders. The reference weight is set by averaging weight measurements over a period after the rider mounts.

Redundant control method for an electric skateboard to improve safety and reliability when controllers fail or disconnect during operation. The skateboard has a master controller, a slave controller, and four motors connected to front and rear wheels. If the CAN bus connection between the controllers fails, the remaining controller sends error info back to the remote control. The remote then redistributes power and sends it to both controllers via Bluetooth. This allows the working controller to assume full control and keep the skateboard operating safely.
