Abstract
An electric roller skate system includes a pair of roller skates, where each of the pair of roller skates includes: a base configured to receive a foot of a rider, where the base comprises a front base and a rear base, where a distance between the front base and the rear base is adjustable; a front main body attached to the front base; a rear main body attached to the rear base; an ankle strap attached to the rear main body; two front wheels attached to a bottom of the front base; a rear wheel attached to a bottom of the rear base, where a cross-section of the rear wheel has a barrel shape; a battery; and an electric motor mechanically coupled to the rear wheel.
Claims20
An electric roller skate system comprising:
- a pair of roller skates operable in a configuration mode and a normal mode, wherein each roller skate of the pair of roller skates comprises:
- a base configured to receive a foot of a rider, wherein the base comprises a front base and a rear base, wherein a distance between the front base and the rear base is adjustable;
- a front main body attached to the front base;
- a rear main body attached to the rear base;
- an ankle strap attached to the rear main body, wherein the front main body, the rear main body, and the ankle strap are configured to fasten the foot of the rider to the base;
- two front wheels attached to a bottom of the front base;
- a rear wheel attached to a bottom of the rear base, wherein a cross-section of the rear wheel has a barrel shape;
- a battery;
- an electric motor mechanically coupled to the rear wheel;
- and
- a speed sensor a speed sensor configured to measure a speed of the roller skate, wherein the electric roller skate system is configured to perform a calibration of the speed sensors of the pair of roller skates by:
- setting the pair of roller skates in a calibration mode;
- recording a plurality of sets of speed measurement provided by the speed sensors of the pair of roller skates, wherein each set of speed measurement comprises a first speed measurement provided by the first speed sensor, and comprises a second speed measurement provided by the second speed sensor;
- and
- performing a curve fitting process using the plurality of sets of speed measurement to generate a fitting curve for use by the pair of roller skates in a normal mode of operation, wherein the fitting curve indicates a one-to-one mapping between the first speed measurement and the second speed measurement at different speeds.
12 more elements
An electric roller skate system comprising:
- a remote control;
- a first roller skate comprising a first sensor configured to measure a speed of the first roller skate and a first memory configured to record a first data set of measured speeds of the first roller skate;
- and
- a second roller skate comprising a second sensor configured to measure a speed of the second roller skate and a second memory configured to record a second data set of measured speeds of the second roller skate, wherein the first roller skate and the second roller skate are configured to communicate with the remote control through wireless communication, wherein each roller skate of the first and second roller skates comprises:
- a base configured to receive a foot of a rider, wherein the base comprises a front base and a rear base, wherein a distance between the front base and the rear base is adjustable;
- an ankle strap configured to fasten the foot of the rider to the base;
- two front wheels attached to a bottom of the front base;
- a rear wheel attached to a bottom of the rear base, wherein a cross-section of the rear wheel has a barrel shape;
- a battery;
- an electric motor mechanically coupled with the rear wheel;
- and
- a processor configured to generate a fitting curve from the first and second data sets, wherein the fitting curve indicates a one-to-one mapping between the measured speeds of the first roller skate and the measured speeds of the second roller skate, wherein the electric motor of the second roller skate is configured to adjust its speed to match a target speed of the electric motor of the first roller skate according to a result of the fitting curve.

An electric roller skate system comprising:
- a remote control;
- and
- a pair of roller skates, wherein the pair of roller skates are configured to communicate with the remote control through wireless communication, wherein each roller skate of the pair of roller skates comprises:

- two front wheels attached to a bottom of the front base via a steering truck;
- a rear wheel attached to a bottom of the rear base, wherein a cross-section of the rear wheel has a barrel shape, wherein the rear wheel has two straight sidewalls on opposing sides and a first width as measured from a first one of the straight sidewalls of the rear wheel to a second one of the straight sidewalls of the rear wheel and each of the front wheels has two straight sidewalls on opposing sides and a second width as measured from a first one of the straight sidewalls of the front wheel to a second one of the straight sidewalls of the front wheel, and wherein the first width is greater than or equal to twice the second width;
- a speed sensor coupled to the rear wheel;
- a battery;
- and
- an electric motor mechanically coupled with the rear wheel and powered by the battery.
