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 powered board vehicle, comprising:
a flexible deck having a forward portion and a rearward portion;
at least one front wheel connected with the deck under the forward portion, the front wheel configured to swivel about a first axis and rotate about a second axis; and
a powered rear wheel connected with the deck and in a fixed alignment relative to the deck, wherein the powered rear wheel comprises a hub motor configured to drive the powered rear wheel from a position laterally offset along an axis of rotation of the powered rear wheel such that the hub motor is disposed outside of the powered rear wheel and a longitudinal axis of the hub motor is generally collinear with the axis of rotation, wherein the powered rear wheel further comprises a central plane disposed along a longitudinal axis of the vehicle, and wherein the hub motor is laterally offset from the central plane;
wherein the deck permits rotation of the forward portion relative to the rearward portion to permit a user to twist the forward portion relative to the rearward portion in alternating directions about a longitudinal axis of the deck.

2. The vehicle of claim 1 , wherein the front wheel and the rear wheel are aligned with the longitudinal axis of the vehicle.

3. The vehicle of claim 1 , wherein a diameter of the front wheel is different from a diameter of the rear wheel.

4. The vehicle of claim 1 , wherein a diameter of the front wheel is equal to a diameter of the rear wheel.

5. The vehicle of claim 1 , wherein the vehicle further comprises two front, swivelable wheels connected with the deck under the forward portion, the two front wheels aligned such that an axis passing through a center of each of the front wheels is orthogonal to the longitudinal axis of the vehicle when the two front wheels are aligned parallel to the longitudinal axis of the vehicle.

6. The vehicle of claim 5 , wherein the two front wheels are supported by a mounting bracket that is supported by the deck, wherein the mounting bracket is configured to move relative to the deck.

7. The vehicle of claim 6 , wherein the mounting bracket can pivot or rock relative to the deck.

8. The vehicle of claim 1 , further comprising a rotational coupling or other torsional-flex-facilitating structure between the forward portion and the rearward portion of the deck.

9. The vehicle of claim 8 , wherein the rotational coupling includes one or more pivot assemblies and a biasing element to bias the forward portion and the rearward portion into a neutral or aligned relative position.

10. The vehicle of claim 1 , wherein the deck further comprises a molded plastic platform to provide a gripping surface on a top surface of the deck.

11. The vehicle of claim 1 , wherein the deck further comprises a thin portion in a lateral direction between the forward portion and the rearward portion to allow the deck to twist or flex.

12. The vehicle of claim 11 , wherein a lateral axis bisects the deck at a midpoint of the deck, the lateral axis orthogonal to the longitudinal axis of the deck, the forward portion of the deck narrows to a point forward of the lateral axis and the thin portion is rearward of the lateral axis.

13. The vehicle of claim 1 , wherein the deck is relatively consistent in lateral width throughout at least a midpoint of a length of the deck and wherein a source of power is supported by the deck.

14. The vehicle of claim 1 , further comprising a wired or wireless remote control that controls the powered rear wheel.

15. The vehicle of claim 1 , wherein the hub motor further comprises a mount configured to support the hub motor, and wherein at least a portion of the hub motor is laterally offset inboard of the mount and at least a portion of the hub motor is laterally offset outboard of the mount.

16. A powered personal mobility vehicle, comprising:
a body having a deck, the deck being configured to support a user, the deck having a forward portion and a rearward portion;
a caster assembly connected with the deck;
at least one front wheel connected with the caster assembly and rotatable about a first axis;
a rear wheel connected with the body and rotatable about a second axis; and
a hub motor connected with the body and arranged to transfer rotational force to the rear wheel from a position laterally offset along the second axis of the rear wheel such that the hub motor is disposed outside of the rear wheel;
wherein the forward and the rearward portions are spaced apart by a neck portion that is laterally narrower than both the forward portion and the rearward portion, thereby allowing the deck to twist or flex about a longitudinal axis of the vehicle that passes through the neck,
wherein the rear wheel comprises a central plane disposed along a longitudinal axis of the powered personal mobility vehicle, and wherein the hub motor is laterally offset from the central plane.

17. The vehicle of claim 16 , further comprising two front caster wheels connected to a mounting bracket connected to the body such that an axis passing through a center of each of the front wheels is orthogonal to a longitudinal axis of the body when the front caster wheels are oriented parallel to the longitudinal axis of the body.

18. The vehicle of claim 17 , wherein the mounting bracket is configured to move relative to the deck.

19. The vehicle of claim 16 , wherein the front wheel and the rear wheel are aligned with the longitudinal axis of the vehicle.

20. A vehicle assembly comprising:
the powered personal mobility vehicle claim 16 ; and
a remote control configured to wirelessly communicate with a control unit on vehicle, the control unit comprising a processor and a receiver, the control unit configured to control the amount of power provided to the motor.

21. The vehicle of claim 16 , wherein the hub motor further comprises a mount configured to support the hub motor, and wherein at least a portion of the hub motor is laterally offset inboard of the mount and at least a portion of the hub motor is laterally offset outboard of the mount.

22. A powered board vehicle, comprising:
a flexible deck having a forward portion and a rearward portion;
at least one front wheel connected with the deck under the forward portion, the front wheel configured to swivel about a first axis and rotate about a second axis; and
a powered rear wheel connected with the deck and in a fixed alignment relative to the deck, the powered rear wheel comprising a hub motor configured to drive the powered rear wheel from a position laterally offset along an axis of rotation of the powered rear wheel such that the hub motor is disposed outside of the powered rear wheel and such that a longitudinal axis of the hub motor is generally collinear with the axis of rotation;
wherein the hub motor comprises a mount configured to support the hub motor, and wherein at least a portion of the hub motor is laterally offset inboard of the mount and at least a portion of the hub motor is laterally offset outboard of the mount; and
wherein the deck permits rotation of the forward portion relative to the rearward portion to permit a user to twist the forward portion relative to the rearward portion in alternating directions about a longitudinal axis of the deck.

23. The vehicle of claim 22 , wherein the vehicle further comprises two front, swivelable wheels connected with the deck under the forward portion, the two front wheels aligned such that an axis passing th
