Claims27
A personal mobility vehicle comprising:
- a body having a support surface and being configured to support a user;
- a plurality of wheels comprising a driving wheel and a front wheel;
- a drive assembly configured to be selectively detached from the body, the drive assembly comprising:
- a motor and a drive shaft;
- a power supply housing;
- a transmission assembly comprising a gear transmission, the gear transmission comprising at least a driving gear connected to the drive shaft and a driven gear configured to spin the driving wheel;
- and
- a power supply configured to power the drive assembly and to cause the motor to spin the driving wheel;
- and
- a pressure sensor configured to detect pressure from the user supported by the body of the personal mobility vehicle.
7 more elements
A drive assembly configured for use in a personal mobility vehicle, the drive assembly comprising:
- a driving wheel;
- a power supply housing;
- a motor and a drive shaft;
- a transmission assembly comprising a gear transmission, the gear transmission comprising at least a driving gear connected to the drive shaft and a driven gear configured to spin the driving wheel;
- a power supply configured to power the drive assembly and to cause the motor to spin the driving wheel, wherein the motor is configured to communicate with a controller of the personal mobility vehicle, the controller configured to receive signals from a pressure sensor on the personal mobility vehicle;
- and
- a locking mechanism configured to selectively secure the power supply to the personal mobility vehicle.
4 more elements
A personal mobility system comprising:
- a powered skate comprising:
- a body comprising a first foot support surface;
- a first wheel on a first end of the powered skate and a second wheel on a second end of the powered skate opposite the first end, one of the first and second wheels being a driving wheel;
- and
- a drive assembly, comprising:
- a power supply housing;
- a motor and a drive shaft;
- a transmission assembly comprising a gear transmission, the gear transmission comprising at least a driving gear connected to the drive shaft and a driven gear configured to spin the driving wheel;
- and
- a power supply configured to power the drive assembly and to cause the motor to spin the driving wheel, the power supply configured to be selectively removed from the power supply housing;
- and
- a non-powered skate comprising:
- a body comprising a second foot support surface;
- a first wheel on a first end of the non-powered skate and a second wheel on a second end of the non-powered skate opposite the first end;
- and
- wherein a direction of travel of the personal mobility vehicle is generally perpendicular to a longitudinal axis of a user's foot.
13 more elements
A personal mobility vehicle comprising:
- a body having a support surface and being configured to support a user;
- a plurality of wheels comprising a driving wheel and a front wheel;
- a drive assembly comprising:
- a motor and a drive shaft;
- a power supply housing positioned above the driving wheel;
- a power supply configured to be received in the power supply housing and to provide electric power to the motor to cause the motor to spin the driving wheel, the power supply being removable from the power supply housing;
- and
- a pressure sensor configured to transmit a signal indicative of the user being supported on the body;
- and
- a controller configured to energize the motor at least partly in response to receipt of the signal.
