Advanced Braking for Electric Skateboards

Braking system for skateboards and similar rideable vehicles that provides even braking force without affecting steering. The system uses a modular brake activation mechanism that can be triggered by various mechanisms like kick tails, pedals, levers, or tethers. The brake has a hanger with a pivot cup, a baseplate with a trigger, and a push rod connecting them. When the trigger moves the push rod, it presses against the hanger to close a hinge and apply brake force to the wheels. The baseplates have different pivot angles for various wheelbases. The hanger has a compression spring to resist hinge closure. The baseplate and hanger designs allow even brake force on both wheels. The modular brake mechanism can be adapted for different riding styles and vehicles.

Brake-by-wire system for skateboards that replaces traditional hydraulic brakes with an electromagnetic brake. The system uses magnetostrictive materials and electromagnets to adjust brake force. The skateboard chassis has a hub motor, brake disc, and two supports with magnetostrictive blocks and electromagnets. Controlling current in the electromagnets changes the magnetic field around the magnetostrictive blocks. This causes them to contract or expand, pressing the friction block against the brake disc for braking force. The system provides adjustable braking capability without hydraulics or mechanical links.

Electromagnetic brake system for skateboard-style chassis of commercial vehicles that allows high integration and reduced space compared to pneumatic brakes. The system uses magnetostrictive materials to generate braking force. It has a brake drum, brake base plate, mechanical module, and driving module. The driving module has an electromagnet with magnetostrictive material that expands when current is applied, pushing against the mechanical module to apply braking force on the brake drum. The system is optimized using a multi-objective optimization method to balance factors like braking force, displacement amplification, and efficiency.

Skateboard with a built-in braking mechanism that allows stopping the board without having to lift a foot. The skateboard has a frame attached to the bottom with a pulley. A sliding groove in the board allows a brake pedal to move back and forth. When the pedal is pushed, it engages brake pads on the bottom surface of the board near the pulley. This brings the pads into contact with the ground to brake the skateboard. The pedal has a push member to move the brake block.

A brake-by-wire system for skateboard chassis of commercial vehicles that provides consistent braking performance across different road conditions and loads. The system uses sensors to estimate road conditions and loads, and a control algorithm to compensate for braking inconsistencies caused by factors like motor regenerative braking, air brake hysteresis, and weight changes. The algorithm adjusts the distributed braking forces between electric and pneumatic brakes based on estimated road conditions and loads. This allows consistent braking despite uncertainty in factors like motor regenerative braking force, air brake friction, and load changes. The control algorithm also limits the brake output to prevent overcompensation.

A braking system with a rotating element like a wheel, brake disc or drive wheel/pinion and a braking device with two braking elements and a leaf spring to release the brake. The first braking element has an annular braking surface. The second braking element is fixed. The rotating element has two friction surfaces opposite the annular braking surface. In the braking position, the first element presses the rotating element against the fixed second element to brake it. A leaf spring moves the first element back to the rest position.

A braking device for skateboards that allows for safe and efficient braking, particularly in emergency situations. The device is attached to the skateboard and includes a lever that can be manually actuated by the rider to engage a braking mechanism. When activated, the braking mechanism applies pressure to the skateboard wheels to slow down and stop the skateboard.

A braking device for skateboards that provides a safe, efficient and effective way to stop the board in emergency situations. The device attaches to the rear truck of the skateboard and has a lever that can be activated by the rider's foot. When the lever is engaged, it applies braking force to the wheel to slow down the skateboard. This allows the rider to avoid accidents by quickly and easily stopping the board in an emergency. The lever can be designed to be easy to operate while riding, like a pedal or footrest, and can be disengaged for regular riding.

Skateboard that can automatically decelerate when going downhill without friction between the board surface and the ground. The skateboard has a mechanism that slows it down when going downhill without the need for friction between the board and the ground. The mechanism uses a spring-loaded piston that extends when the skateboard is going downhill to apply braking force. A magnet inside the piston cylinder attracts a magnet on the skateboard deck to pull it back. This creates a self-contained braking system that decelerates the skateboard without contacting the ground.

Automatic brake for skateboards and longboards that engages when the board is not in motion to prevent uncontrolled runs. The brake has four cylindrical tubes welded to the truck base inside coiled springs. It also has a support welded to the truck and a separate support bolted to the board. This configuration allows the hanger to pivot freely while the brake engages when the board is at rest.

A brake system for skateboards and similar boards that provides a simple and effective way to brake without modifying the board itself. The brake is a device that attaches underneath the board and has a brake plate that contacts the ground to slow or stop the board. It uses a rubber band or other friction material to brake when the plate is pressed against the ground. The brake plate is activated by pulling a lever on the side of the board, which releases the rubber band and allows the plate to move down and touch the ground. This provides a convenient and accessible brake system for skateboards and other boards that doesn't require modifying the board itself.

Skateboard with a mechanical device to store and return braking energy without batteries. The skateboard has a torsion spring under the board that stores braking energy. The spring can be disconnected from the wheels when fully wound or fully unwound. Movable plates on the front and rear of the board apply pressure to control spring operation. A torque limiter on the front wheels disconnects the spring when fully wound. A free wheel on the rear wheels disconnects when fully unwound. Gears can also disconnect the spring when no pressure is applied.

Electric skateboard brake system that uses embedded mini hub hydraulic brakes instead of external brakes. The brake mechanism is integrated inside the skateboard wheel hub. It consists of a small oil cylinder with brake pads, a return spring, and a piston. The cylinder is connected to the skateboard bridge through an oil passage. The brake is actuated by an external lever or pedal that pushes the piston into the cylinder. This compresses the spring and squeezes the brake pads against the wheel rim to stop the skateboard. The embedded hub brake provides high braking efficiency, compact size, and improved safety compared to external brakes.

A self-balancing board with a primary wheel and motor assembly for propulsion, an elevated auxiliary wheel that contacts the ground when the board tilts, and a manually engageable brake to resist rotation of the auxiliary wheel. The board uses sensors to detect tilt and balance and adjusts the motorized primary wheel to maintain balance. The elevated auxiliary wheel prevents the primary wheel from braking when the board is stationary. The brake allows the user to prevent rolling. This configuration provides stability when still, self-balancing when moving, and user control over motion.

A brake system for skateboards, particularly longboards, that allows the rider to slow down and stop the board using replaceable friction pads. The brake is attached to the bottom of the deck near the rear truck. The rider applies force to a pedal that connects through the deck to displace the pads against the ground. This generates friction to slow the board. The pads can be easily replaced. The brake's force is normal to the board's motion, opposing velocity/acceleration.
