Hoverboard which generates magnetic lift to carry a person
A hoverboard is described. The hoverboard includes four hover engines each including a motor. The motor rotates an arrangement of magnets to induce eddy currents and generate magnetic lift which causes the hoverboard to hover in the air. The hoverboard can be tilted to propel it in a particular direction. The hover engines can each be coupled to a tilt mechanism which is coupled to a flexible rider platform. When rider platform is flexed via rider induced forces, the hover engines can be tilted individually to provide translational forces.
1. A hoverboard comprising:
two or more hover engines, each hover engine having,
an electric motor including a winding, a first set of permanent magnets and a first structure which holds the first set of permanent magnets wherein an electric current is applied to the winding to cause one of the winding or the first set of permanent magnets to rotate;
an electronic speed controller which controls a rotation rate of the electric motor;
a rotatable component, configured to receive a rotational torque from the electric motor which rotates the rotatable component including a second set of permanent magnets and a second structure which holds the second set of permanent magnets wherein the second set of permanent magnets are rotated to induce eddy currents in a substrate such that the induced eddy currents and the second set of permanent magnets interact to generate forces which cause the hoverboard and a person standing on the hoverboard to hover and translate from location to location along the substrate; and
a shroud enclosing the electric motor and at least a top portion of the rotatable component;
an electric power source that outputs the electric current to the two or more hover engines;
a rider platform on which the person stands, the two or more hover engines structurally linked to the rider platform;
a mechanical hinge coupled to a first hover engine of the two or more hover engines which allows the rotatable component, the electric motor and the shroud of the first hover engine to tilt relative to the rider platform wherein a magnitude of a translational force, output from the first hover engine, changes in response to tilting the rotatable component, the electric motor and the shroud and wherein the translation force is used to control an orientation of the hoverboard relative to the substrate;
an actuator, including an actuator controller, which outputs a force that changes a tilt position of the first hover engine from a first tilt position to a second tilt position in response to an input force generated by the person;
one or more sensors configured to measure a direction and/or a magnitude of the input force generated by the person; and
a logic device configured to receive sensor data from the one or more sensors, communicate with the actuator controller and based upon the sensor data, command the actuator controller to output the force to tilt the first hover engine.
2. The hoverboard of claim 1 , further comprising a plurality of mechanical hinges and tilt mechanisms each coupled to the two or more hover engines.
3. The hoverboard of claim 1 , wherein the one or more sensors are integrated into the rider platform and wherein the person generates the input force via a movement of their body.
4. The hoverboard of claim 1 , wherein the one or more sensors are located in an electronic device worn or held by the person.
5. The hoverboard of claim 1 , a mechanical linkage which receives a second input force from the person and converts the second input force to an external force to tilt the first hover engine.
6. The hoverboard of claim 5 , wherein the mechanical linkage is coupled to the shroud of the first hover engine on a first end and extends through an aperture in the rider platform.
7. The hoverboard of claim 6 , wherein the mechanical linkage is configured to receive the second input force from the person on a second end.
8. A hoverboard comprising:
two or more hover engines, each hover engine having,
an electric motor including a winding, a first set of permanent magnets and a first structure which holds the first set of permanent magnets wherein an electric current is applied to the winding to cause one of the winding or the first set of permanent magnets to rotate;
an electronic speed controller which controls a rotation rate of the electric motor; a rotatable component, configured to receive a rotational torque from the electric motor which rotates the rotatable component including a second set of permanent magnets and a second structure which holds the second set of permanent magnets wherein the second set of permanent magnets are rotated to induce eddy currents in a substrate such that the induced eddy currents and the second set of permanent magnets interact to generate forces which cause the hoverboard and a person standing on the hoverboard to hover and translate from location to location along the substrate; and
a shroud enclosing the electric motor and at least a top portion of the rotatable component;
an electric power source that outputs the electric current to the two or more hover engines;
a rider platform on which the person stands, the two or more hover engines structurally linked to the rider platform;
a mechanical hinge coupled to a first hover engine of the two or more hover engines which allows the rotatable component, the electric motor and the shroud of the first hover engine to tilt relative to the rider platform wherein a magnitude of a translational force, output from the first hover engine, changes in response to tilting the rotatable component, the electric motor and the shroud and wherein the translation force is used to control an orientation of the hoverboard relative to the substrate;
a first portion of the rider platform that is moveable relative to a remaining portion of the rider platform; and
a mechanical linkage coupled on a first end to the shroud of the first hover engine and coupled on a second end to the first portion wherein the first portion moves in response to receiving an input force from a foot of the person which causes the first hover engine to tilt.
9. The hoverboard of claim 8 , wherein the first portion is formed from a rigid material which is coupled to the remaining portion of the rider platform via a second mechanical hinge.
10. The hoverboard of claim 8 , wherein the first portion is formed from a flexible material which bends in response to the input force from the foot of the person.
11. The hoverboard of claim 8 , wherein the second end of the mechanical linkage is mounted through a bottom surface of the first portion and passes through an aperture in the remaining portion of the rider platform.
