Abstract

Various powered wheeled board vehicles are disclosed. In some embodiments, the vehicle includes a deck having a forward portion and a rearward portion. At least one front wheel can be connected with the deck under the forward portion. The front wheel can be configured to swivel about a first axis and rotate about a second axis. A powered wheel can be connected with the rearward portion. In some configurations, the rear wheel comprises a hub motor.

First claim

What is claimed is:

1. A personal mobility vehicle, comprising:
a deck configured to support a user, the deck having a first portion and a second portion, the first and the second portions spaced apart by a neck portion, the neck portion being configured to enable the deck to twist or flex about a longitudinal axis of the vehicle, wherein a first end of the neck portion extends at least partially into the first portion of the deck and a second end of the neck portion extends at least partially into the second portion of the deck;
a first swivel wheel and a second swivel wheel, each of the first and second swivel wheels being connected with the first portion of the deck and disposed entirely beneath the deck, wherein the first swivel wheel is connected with the first portion of the deck at a first location, and wherein the second swivel wheel is separately connected with the first portion of the deck at a second location laterally offset from the first location; and
a third wheel connected with the second portion of the deck and disposed entirely beneath the deck.

2. The vehicle of claim 1 , wherein the vehicle is configured such that locomotion is caused or increased by twisting or flexing the first and second portions of the deck relative to each other along the longitudinal axis of the vehicle.

3. The vehicle of claim 1 , wherein the first portion of the deck is configured to receive a first foot of the user and the second portion of the deck is configured to receive a second foot of the user.

4. The vehicle of claim 1 , wherein the first and second swivel wheels are aligned such that an axis passing through a center of each of the swivel wheels is orthogonal to the longitudinal axis of the vehicle when the swivel wheels are aligned parallel to the longitudinal axis of the vehicle.

5. The vehicle of claim 1 , wherein each of the swivel wheels is supported by a mounting bracket that is supported by the deck, wherein each of the mounting brackets is configured to move relative to the deck.

6. The vehicle of claim 1 , wherein the first swivel wheel and the second swivel wheel are substantially equal in diameter.

7. The vehicle of claim 1 , wherein at least one of the wheels is configured to swivel 360 degrees about its respective swivel axis.

8. The vehicle of claim 1 , wherein the first swivel wheel and the second swivel wheel swivel independently.

9. The vehicle of claim 1 , further comprising a rotational coupling between the first portion and the second portion of the deck.

10. The vehicle of claim 1 , further comprising a motor, wherein a portion of the motor is integrated with one of the wheels.

11. The vehicle of claim 1 , wherein the first portion of the deck comprises a front portion of the deck and the second portion of the deck comprises a rear portion of the deck.

12. The vehicle of claim 1 , wherein the neck portion comprises an exposed section of the neck portion spacing the first portion of the deck apart from the second portion of the deck, the exposed section of the neck portion extending between a receiving aperture of the first portion of the deck and a receiving aperture of the second portion of the deck.

13. The vehicle of claim 1 , wherein the first portion of the deck has a first edge opposite the neck portion and extending generally perpendicular to a direction of travel of the vehicle and the second portion of the deck has a second edge opposite the neck portion and extending generally perpendicular to the direction of travel of the vehicle, wherein the first edge has a first length, and wherein the second edge has a second length different than the first length.

14. A powered personal mobility vehicle, comprising:
a deck configured to support a user, the deck having a first portion and a second portion, the first and the second portions spaced apart by a neck portion, wherein a first end of the neck portion extends at least partially into the first portion of the deck and a second end of the neck portion extends at least partially into the second portion of the deck;
a first swivel wheel and a second swivel wheel, each of the first and second swivel wheels being connected with the first portion of the deck and disposed entirely beneath the deck, wherein the first swivel wheel is connected with the first portion of the deck at a first location, and wherein the second swivel wheel is separately connected with the first portion of the deck at a second location laterally offset from the first location;
a third wheel connected with the second portion of the deck and disposed entirely beneath the deck;
a motor arranged to transfer rotational force; and
a drive shaft configured to transmit torque from the motor.

15. The vehicle of claim 14 , wherein the first portion of the deck is configured to receive a first foot of the user and the second portion of the deck is configured to receive a second foot of the user.

16. The vehicle of claim 15 , wherein the deck is configured to flex or twist in response to pressure from the user's feet.

17. The vehicle of claim 14 , wherein the first and second swivel wheels are aligned such that an axis passing through a center of each of the swivel wheels is orthogonal to a longitudinal axis of the vehicle when the swivel wheels are aligned parallel to the longitudinal axis of the vehicle.

18. The vehicle of claim 14 , wherein each of the swivel wheels is supported by a mounting bracket that is supported by the deck, wherein each of the mounting brackets is configured to move relative to the deck.

19. The vehicle of claim 14 , wherein the first swivel wheel and the second swivel wheel swivel independently.

20. The vehicle of claim 14 , further comprising a rotational coupling between the first portion and the second portion of the deck.

21. The vehicle of claim 14 , wherein a portion of the motor is integrated with one of the wheels.

22. The vehicle of claim 14 , wherein the first portion of the deck comprises a front portion of the deck and the second portion of the deck comprises a rear portion of the deck.
