Abstract

Various powered personal mobility vehicles are disclosed. In some embodiments, the vehicle can include a deck having a forward portion, a rearward portion, and a neck portion. A front swivel wheel assembly and a rear swivel wheel assembly can be connected with the deck. In some embodiments, the front swivel wheel assembly comprises a motor.

Claims (53)

1 . A powered two-wheeled board comprising:

a deck configured to support a rider, the deck comprising:

a forward portion comprising a battery, and a controller;

a rearward portion; and

a neck portion between the forward and rearward portions, the neck portion configured to enable the forward and rearward portions to twist relative to each other about a longitudinal axis of the board;

a front drive wheel assembly connected to the forward portion of the deck, the front drive wheel assembly comprising a front swivel wheel, an electric motor, a mounting plate that supports the front swivel wheel and the electric motor, and a cover that extends along a portion of the mounting plate, the front swivel wheel having an outside diameter with a front edge and a rear edge; and

a rear wheel assembly connected to the rearward portion of the deck, the rear wheel assembly comprising a rear swivel wheel;

wherein the front swivel wheel and the rear swivel wheel are positioned along the longitudinal axis and disposed entirely beneath the deck;

wherein, in a direction parallel to the longitudinal axis, the front edge of the front swivel wheel is forward of the battery and the rear edge of the front swivel wheel is forward of the controller; and

wherein the cover is configured to protect a part of an electrical connection that extends between the electric motor and the battery.

2 . The powered two-wheeled board of claim 1 , wherein the battery extends downwardly below a bottom surface of the forward portion.

3 . The powered two-wheeled board of claim 1 , wherein the battery is laterally wider than the controller and the controller is laterally wider than the front swivel wheel.

4 . A powered two-wheeled board comprising:

a deck configured to support a rider, the deck comprising:

a forward portion comprising a battery, a controller, and a recess, the battery being located rearward of the recess;

a rearward portion; and

a neck portion between the forward and rearward portions, the neck portion configured to enable the forward and rearward portions to twist relative to each other about a longitudinal axis of the board;

a front drive wheel assembly connected to the forward portion of the deck, the front drive wheel assembly comprising a mounting shaft, a front swivel wheel, and an electric motor, a top of the mounting shaft extending into the recess in the forward portion, a rear edge of the recess being forward of an axis of rotation of the front swivel wheel; and

a rear wheel assembly connected to the rearward portion of the deck, the rear wheel assembly comprising a rear swivel wheel.

5 . The powered two-wheeled board of claim 4 , wherein the controller is located rearward of the recess.

6 . The powered two-wheeled board of claim 4 , wherein the battery is positioned lower than the recess.

7 . A powered two-wheeled board comprising:

a forward portion configured to support a first foot of a rider, the forward portion comprising: a front end, a rear end, a sidewall that extends between the front end and the rear end, a battery, a controller, a power switch, and a charging port;

wherein the sidewall having a laterally outward taper from the front end to a front width apex and a laterally inward taper from the front width apex to the rear end, the power switch and the charging port positioned on the laterally inward taper of the sidewall;

a front drive wheel assembly connected to the forward portion, the front drive wheel assembly comprising a front swivel wheel and an electric motor;

a rearward portion configured to support a second foot of a rider, the rearward portion comprising a front end and a rear end;

a rear wheel assembly connected to the rearward portion, the rear wheel assembly comprising a rear swivel wheel; and

a neck portion connected to the rear end of the forward portion and to the front end of the rearward portion, the neck portion configured to enable the forward and rearward portions to twist relative to each other about a longitudinal axis of the board.

8 . The powered two-wheeled board of claim 7 , wherein the charging port is positioned closer to the controller than the power switch is positioned to the controller.

9 . The powered two-wheeled board of claim 7 , further comprising a remote control dock, the remote control dock and the power switch on the same lateral side of the board.

10 . The powered two-wheeled board of claim 7 , wherein the power switch comprises a button.

11 . A powered two-wheeled board comprising:

a forward portion configured to support a first foot of a rider, the forward portion comprising: a front end, a rear end, a sidewall that extends between the front end and the rear end, a battery, a controller, a power switch that is adjacent the controller, and a charging port that is adjacent the controller;

a front drive wheel assembly connected to the forward portion, the front drive wheel assembly comprising a front swivel wheel and an electric motor, the front swivel wheel having an outside diameter with a front edge and a rear edge;

a neck portion connected to the rear end of the forward portion and to the front end of the rearward portion, the neck portion configured to enable the forward and rearward portions to twist relative to each other about a longitudinal axis of the board.

12 . The powered two-wheeled board of claim 11 , wherein, in a direction parallel to the longitudinal axis, the entirety of the power switch is between a front edge and a rear edge of the controller.

13 . The powered two-wheeled board of claim 11 , wherein, in a direction parallel to the longitudinal axis, the power switch and the charging port are between a front edge and a rear edge of the controller.

14 . A powered two-wheeled board comprising:

a deck configured to support a rider, the deck comprising:

a forward portion comprising a battery and a controller;

a rearward portion; and

a neck portion between the forward and rearward portions, the neck portion configured to enable the forward and rearward portions to twist relative to each other about a longitudinal axis of the board;

a front swivel drive wheel assembly connected to the forward portion of the deck, the front swivel drive wheel assembly comprising:

a mount connected to the forward portion of the deck and configured to swivel relative to the forward portion of the deck;

an electric motor connected to the mount, the electric motor comprising an outside surface, a first axial side having a first ridge, a second axial side with a second ridge, and a plurality of protrusions extending between the first ridge and the second ridge; and
