DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS

Embodiments of systems, components and methods of assembly and manufacture will now be described with reference to the accompanying figures, wherein like numerals refer to like or similar elements throughout. Although several embodiments, examples and illustrations are disclosed below, it will be understood by those of ordinary skill in the art that the inventions described herein extends beyond the specifically disclosed embodiments, examples and illustrations, and can include other uses of the inventions and obvious modifications and equivalents thereof. The terminology used in the description presented herein is not intended to be interpreted in any limited or restrictive manner simply because it is being used in conjunction with a detailed description of certain specific embodiments of the inventions. In addition, embodiments of the inventions can comprise several novel features and no single feature is solely responsible for its desirable attributes or is essential to practicing the inventions herein described.

Overview

Various embodiments of powered wheeled board vehicles are disclosed. As described in more detail below, the vehicles can include one or more powered rear wheels and one or more swivelable (e.g., caster) front wheels, among other wheels. Conventionally, this combination would be thought to render the vehicle inherently unstable, difficult to ride, and/or hard to control. This combination was typically thought to be particularly problematic when used on vehicles (e.g., skateboards) configured to permit twisting or flexing of the deck.

Furthermore, the addition of a powered rear wheel would typically be thought to negate the need for a swivelable front wheel. Some vehicles include swivelable front and rear wheels, as well as a deck that is configured to twist or flex, which can allow the user to create a locomotive force. But, with the addition of the powered rear wheel to provide the locomotive force, the swivelable front wheel would typically be thought to be unneeded. Accordingly, the swivelable front wheel would have been replaced with a fixed (e.g., non-swivelable) wheel, such as to reduce cost, increase stability, etc.

Additionally, it was conventionally thought that positioning a powered wheel in the front of certain vehicles was preferred to placing the powered wheel in the rear of the vehicle. For example, having the powered wheel in the rear of the vehicle could be thought to reduce controllability compared to having the powered wheel in the front.

Nevertheless, certain embodiments described herein have shown that a vehicle can include a powered rear wheel and one or more swivelable front wheels. In spite of the aforementioned and other concerns, such a vehicle can be sufficiently controllable and stable to provide an enjoyable riding experience.

Deck

FIGS. 1-8 illustrate an embodiment of a powered wheeled board vehicle 100. The vehicle 100 can include a deck 102, a front wheel assembly 120, and a rear wheel assembly 130.

The deck 102 can be of any suitable size, shape or arrangement. As illustrated in FIGS. 1-8, the deck 102 can include a first or forward portion 110 and a second or rearward portion 112. The forward portion 110 can connect with the front wheel assembly 120 and the rearward portion 112 can connect with the rear wheel assembly 130.

The forward portion 110 can be coupled to the rearward portion 112 by the neck portion 114. In some embodiments, the neck portion 114 rigidly couples the forward portion 110 to the rearward portion 112. In some embodiments, the neck portion 114 flexibly couples the forward portion 110 to the rearward portion 112.

In some embodiments, the neck portion 114 can be laterally narrower than the forward and rearward portions 110, 112. In various embodiments, the neck portion 114 is thinner in the lateral direction than the forward portion 110 and/or the rearward portion 112. For example, a ratio of the maximum lateral width of the forward portion 110 to the maximum lateral width of the neck portion 112 can be at least: 1.5:1, 2:1, 3:1, 4:1, or greater, among other ratios. In some embodiments, a ratio of the maximum lateral width of the rearward portion 112 to the maximum lateral width of the neck portion 112 can be at least: 1.5:1, 2:1, 3:1, 4:1, or greater, among other ratios. Some examples of configurations including a neck portion 114 are shown in FIGS. 1-14B, as well as in U.S. Pat. Nos. 7,338,056, 7,600,768 and 7,766,351, which are hereby incorporated by reference herein in their entirety.

In some configurations, a lateral axis A bisects the deck 102 at a midpoint of the neck portion 114. In some embodiments, the lateral axis A is orthogonal to a longitudinal axis L of the deck 102. In some embodiments, the rearward portion 112 has a shape and/or size that is substantially the same or similar to a shape and/or size of the forward portion 110. In some embodiments, the rearward portion 112 is larger than the forward portion 110. For example, the rearward portion 112 can have a length that is greater than a length of the forward portion 110. Certain such configurations can provide greater stability to the user while the user is being supported by the deck 102. In some embodiments, such configurations can provide easier steering controls to the user and/or allow the user to more easily tilt or twist the vehicle 100.

In some embodiments, the forward portion 110 has a front end 111 and the rearward portion 112 has a rear end 113. The rear end 113 can be wider than the front end 111. In some embodiments, the front end 111 and/or the rear end 113 are substantially concave. For example, an intermediate portion of the front end 111 and/or the rear end 113 can curve inwardly towards a lateral center of the deck 102 (e.g., a portion on the longitudinal axis L). In some embodiments, the front end 111 and/or the rear end 113 are substantially straight. In some embodiments, a portion of the forward portion 110 and/or the rearward portion 112 that connects with the neck portion 114 has a lateral width that is shorter than the front end 111 and/or the rear end 113.

In some embodiments, the rearward portion 112 has a maximum lateral width that is wider closer to the rear end 113 of the rearward portion 112 than to the neck portion 114. Some such configurations can provide enhanced support to the rear wheel assembly and/or to the user. Some such configurations can provide better stability to the user and/or provide a wider platform to secure the foot of the user in use.

In some embodiments, the neck portion 114 is substantially rigid. For example, the neck portion 114 can limit rotation of the rearward portion 112 relative to the forward portion 110 and/or the forward portion 110 relative to the rearward portion 112. In some embodiments, the neck portion 114 can allow the deck 102 to flex, twist, and/or tilt relative to the forward and/or rear portion 110, 112. In various embodiments, the deck 102 can flex, twist, and/or tilt in response to pressure from at least one of the user's feet, such as due to the user's weight shifting laterally on the deck 102. This can result in the forward portion 110 twisting and/or rotating relative to the rearward portion 112 in alternating directions about a longitudinal axis of the deck 102. The flex or twist of the deck 102 can be used to steer, control, and/or propel the vehicle 100. Further description of this feature can be found in at least U.S. Pat. Nos. 7,338,056, 7,600,768 and 7,766,351, which are hereby incorporated by reference herein in their entirety.

Front Wheel Assembly

FIGS. 1-8 illustrate the powered wheeled board vehicle 100 having a deck 102 connected with a front wheel assembly 120. The front wheel assembly 120 can include at least one front wheel 124. The front wheel 124 can be swivelably connected with a caster assembly 126. For example, the front wheel 124 can be a caster wheel. The caster assembly 126 can be coupled to and/or formed with the front wheel assembly mount 122. The caster assembly 126 can allow the front wheel 124 to swivel about a first axis and rotate about a second axis (e.g., generally orthogonal to the first axis).

In some embodiments, the front wheel 124 can be positioned approximately along a longitudinal axis of the vehicle 100 (for example, when the front wheel 124 is in a straight or neutral position). In some embodiments, the front wheel assembly 120 includes a biasing member, such as a spring, that biases the front wheel 124 towards the neutral position.

In some embodiments, the front wheel 124 can be positioned closer to a front end of the forward portion 110 than to the neck portion 114. In some embodiments, the front wheel 124 is positioned at approximately a center of the forward portion 110. In some embodiments, the front wheel assembly mount 122 is positioned closer to the front end of the forward portion 104 than to the neck portion 114 and the front wheel 124 is positioned at approximately a center of the forward portion. The front wheel assembly mount 122 can be inclined. For example, a portion of the mount 122 positioned closer to the front end 111 of the forward portion 104 can be positioned closer to the rolling surface than to a portion of the front wheel assembly 122 mount that is closer to the neck portion 114 when the vehicle 100 is substantially upright.

In some embodiments, the front wheel 124 can be angled. For example, the front wheel 124 can extend away from the front wheel assembly mount 122 at an angle. In some embodiments, when the front wheel 124 is in the neutral position, the front wheel 124 can be angled towards the rear end 113 of the rearward portion 112 (e.g., away from the front end 111 of the forward portion 110). In some embodiments, at least a portion of the front wheel 124 extends rearward of the front wheel assembly mount 122 when the front wheel 124 is in the neutral position. In some embodiments, an axle and/or the second axis of the front wheel 124 is positioned rearward of the front wheel assembly mount 122 when the front wheel 124 is in the neutral position.

Auxiliary Wheel Assembly

FIGS. 1-8 illustrate an embodiment of the vehicle having an auxiliary wheel assembly 180. The auxiliary wheel assembly 180 can include at least one auxiliary wheel 182 and an auxiliary wheel mount 184. As shown in the illustrated embodiment, the auxiliary wheel assembly 180 can include one or more (e.g., at least two auxiliary wheels 182). Some embodiments have one or more (e.g., at least two) auxiliary wheel mounts 184. In some embodiments, the auxiliary wheels 182 are caster wheels. In some embodiments, the auxiliary wheels 182 begin to spin when the wheels 182 touch the ground and the vehicle is already in motion. In some embodiments, the auxiliary wheels 182 can begin to rotate before the wheels 182 touch the ground. For example, in some embodiments, the auxiliary wheels 182 are powered, such as by the motor 152.

The auxiliary wheel mounts 184 can be coupled with the rearward housing portion 134. In some embodiments, the auxiliary wheel mounts 184 are integrally formed with the rearward housing portion 134. As shown, the auxiliary wheel mounts 184 can be positioned rearward at least a portion of the rear wheel assembly 180. In some embodiments, the auxiliary wheel mounts 184 can be spaced laterally from one another along a rear portion of the rearward housing portion 132. In some embodiments, the auxiliary wheel mounts 184 can be positioned adjacent lateral sides of the rearward housing portion 132. In some embodiments, the auxiliary wheel mounts 184 extend rearward from the rearward housing portion 132. In some embodiments, at least a portion of the auxiliary wheel mounts 184 and/or the auxiliary wheels 182 extends rearwardly beyond a rear side of the deck 102. In some embodiments, a rear-most portion of the auxiliary wheels 182 and/or the auxiliary wheel mounts 184 is approximately aligned with the rear end of the deck 102.

In some embodiments, the auxiliary wheel assembly 180 can be angled. For example, at least a portion of the auxiliary wheels 182 can be positioned rearward of a front end of the auxiliary wheel mounts 184. In some embodiments, the axis of rotation of the auxiliary wheels 182 is positioned rearward of the front end of the auxiliary wheel mounts 184. In some embodiments, the axis of rotation of the auxiliary wheels 182 can be positioned below the motor 152. In some embodiments, the axis of rotation of the auxiliary wheels 182 is approximately aligned with the axis of rotation of the rear wheel 134 along an axis that is parallel to the longitudinal axis L of the vehicle. In some embodiments, the auxiliary wheels 182 extend away from the auxiliary wheel assembly mounts 184 at an angle. In some embodiments, at least a portion of the auxiliary wheels 182 is positioned rearward of the rear wheel assembly 130. For example, at least a portion of the auxiliary wheels 182 can be positioned rearward of the motor 152.

In some embodiments, at least a portion of the auxiliary wheels 182 is positioned below an angled rear portion of the deck 102. In some embodiments, at least a portion of the auxiliary wheels 182 is positioned below a substantially straight portion of the deck 102 and the angled rear portion of the deck 102. In some embodiments, at least a portion of the auxiliary wheels 182 is positioned entirely below the substantially straight portion of the deck 102.

In some configurations, the auxiliary wheels 182 and the rear wheel 134 can have different diameters. For example, the rear wheel 134 can have a diameter that is at least twice the diameter of the auxiliary wheels 182. In some embodiments, the rear wheel 134 has a diameter that is at least three, four, or five or more times the diameter of the auxiliary wheels 182.

The auxiliary wheel mounts 184 can rotatably couple the auxiliary wheels 182. In some embodiments, the auxiliary wheel mounts 184 are in a forked shape such that the mounts 184 extend along at least a portion of lateral sides of the auxiliary wheels 182. The mounts 184 can be configured to allow rotation about an auxiliary wheel axis 186. In some embodiments, the auxiliary wheel mounts 184 are configured to inhibit or prevent rotation about an axis that is transverse to the auxiliary wheel axis 186. In some embodiments, the auxiliary wheels 182 are coupled to the auxiliary wheel mounts 184 by an auxiliary wheel axle 188. The auxiliary wheel axle 188 can extend through the auxiliary wheels 182 and at least a portion of the auxiliary mounts 184.

In some embodiments, the auxiliary wheels 182 can provide additional stability and/or to the rearward portion 112 of the deck 102. This can beneficially provide easier steering controls to the user and/or allow the user to more easily tilt or twist. For example, as shown in FIGS. 7 and 8, the auxiliary wheels 182 can extend downwardly from the rearward housing portion 132 a distance less than the rear wheel 134. In such configurations, when the rear wheel 134 contacts the ground in use, one or both of the auxiliary wheels 182 may not contact the ground. In some embodiments, one or both of the auxiliary wheels 182 contacts the ground when the user tilts and/or twists the forward portion relative to the rearward portion. In some embodiments, one or both of the auxiliary wheels 182 contacts the ground when the user turns the vehicle 100. Thus, the auxiliary wheels 182 can help to prevent falls and/or help to keep the vehicle 100 in a generally upright position in use. Such configurations can help the user to balance while riding on the vehicle 100. In some embodiments, the auxiliary wheels 182 can help to inhibit a user from falling off of the vehicle 100, such as backwards to the rear of the vehicle and/or sideways to either side of the vehicle 100. In some embodiments, the auxiliary wheels 182 can limit the amount of front-to-rear tilt of the vehicle, such as during take-off and/or during slow down. In some embodiments, the auxiliary wheels 182 can allow for various tricks and/or styles of riding the vehicle.

Rear Wheel Assembly

As previously mentioned, the powered wheeled board vehicle 100 can include a deck 102 connected with a rear wheel assembly 130. As shown in FIG. 12, the rear wheel assembly 130 can be connected to the rearward portion 112. The rearward portion 112 can include a rearward housing portion 132. As discussed above, the rearward housing portion 132 can support the rear wheel assembly 130, as shown in FIG. 12. The rear wheel assembly 130 can include a rear wheel 134 and a rear wheel mount 136.

In some embodiments, the rear wheel 134 is powered, such as by an electric motor, as discussed below. The rear wheel 134 can be fixed in orientation relative to the deck 102. In some variants, the orientation of the rear wheel 134 is movable relative to the deck 102. The rear wheel 134 can be approximately aligned with and/or positioned on a longitudinal axis of the vehicle 100 (for example, when the front wheel 124 is in a straight or neutral position). In some configurations, the front wheel 124 and the rear wheel 134 can have different diameters. For example, the rear wheel 134 can have a diameter that is at least twice the diameter of the front wheel 124. In some configurations, the front and rear wheels 124, 134 may have substantially the same or the same diameter.

In some embodiments, the rear wheel assembly 130 includes a rear drive assembly 150. The rear drive assembly 150 can include a motor 152. In some embodiments, the motor 152 can be contained in a protective shell, such as a generally cylindrical casing 153. The casing 153 can include one or more apertures, such as to allow airflow from ambient to the motor 152 for cooling. In some embodiments, the motor 152 may be a hub motor similar to those described in U.S. Patent Publication No. 2015/0133253, which is incorporated by reference herein in its entirety. In certain embodiments, the motor 152 may be a small toy motor, such as those used to drive electric motor-driven toys.

The motor 152 can drive the rear wheel 134. In certain embodiments, torque from the motor 152 is transmitted to the rear wheel 134 via a transmission, such as a gear set or gear assembly 154. In some embodiments, the gear assembly 154 can be housed in a gear assembly housing 156. As shown, the gear assembly housing 156 can include a plurality of recesses 162. Each of the recesses 162 can be shaped to receive and/or house a corresponding gear 160 of the gear assembly 154. In some embodiments, the gear assembly housing 156 can include a stepped configuration. For example, the gear assembly housing 156 can include the recesses 162 located at various lateral positions based on the location of the corresponding gear 160 within the gear assembly 162. In some embodiments, as illustrated, the stepped recesses of the gear assembly housing 156 can have respective outer surfaces that are laterally offset (e.g., non-coplanar) from each other.

In some embodiments, the gear assembly housing 156 can include a first portion configured to be positioned at and/or at least partially surround the gears 160. In some embodiments, the gear assembly housing 156 can include a second portion configured to be positioned at an opposite side from the first portion. The second portion can engage the first portion by, for example, a mechanical fastener and/or a snap-fit configuration, to form the gear assembly housing 156 and define an interior space in which the gear assembly 154 is positioned. In some embodiments, the second portion surrounds at least a portion of the gears 160 of the gear assembly 154. In some embodiments, the second portion is removable from the first portion to allow access to the gear assembly 154.

In some embodiments, the gear assembly housing 156 and the casing 153 form a unitary and/or integral unit. In other embodiments, the cylindrical casing 153 is separate from the gear assembly housing 156.

As shown in the exploded view of the rear drive assembly 150 of FIG. 12, the gear assembly 154 can include a plurality of gears 160 (e.g., a worm gear, spur gear, etc.). The gears 160 can be used to convert the torque produced by the motor 152 into a torque that is used to power the rear wheel 134. In some embodiments, the gear assembly 154 includes one, two, three, four, five, six, seven, eight, or nine or more gears 160. Through the sequence of gears 160, the torque of the motor 152 can be changed (e.g., increased or reduced) to drive the rear wheel via the rear wheel axle 155.

In some embodiments, the motor 152 drives a motor shaft 158, such as a driving shaft. In some embodiments, a gear 160a of the gear assembly 154 is mounted on the shaft 158 and a gear 160e of the gear assembly 154 is mounted on the rear wheel axis 155. The gears 160a, 160e can be operably connected through intermediate gears, such as gears 160b, 160c, 160d. Through the sequence of gears 160a-160e, the torque of the motor 152 can be adjusted to drive the rear wheel 134 via the rear wheel axis 155.

Referring back to FIG. 8, a rear view of the vehicle 100 is shown. As shown, the gear assembly 154 can be positioned offset from a longitudinal axis of the vehicle 100. For example, all or a portion of the gears 160 can be positioned on a first side of the longitudinal axis of the vehicle 100. In some embodiments, all or a portion of the gears 160 can be positioned on a first side of the rear wheel 134. As shown, in some embodiments, the motor 152 can be positioned behind the rear wheel 134. In some embodiments, a center of the motor 152 can be substantially aligned with the longitudinal axis of the vehicle 100. In some embodiments, the motor 152 can be positioned approximately perpendicular to the longitudinal axis of the vehicle 100. In some embodiments, the motor 152 can extend between at least a portion of the auxiliary wheel assembly 180, such as the auxiliary wheels 182 and/or the auxiliary wheel mounts 184. In some embodiments, the motor can be configured to pass through a motor slot 163a in the rearward housing portion 132, as illustrated in FIG. 12.

Returning to FIG. 12 again, in some embodiments, the rear drive assembly includes a plurality of gear shafts 159. The gear shafts 159 can be configured to pass through and be rotatably coupled with the gears 160. The gear shafts 159 can extend from a first side housing 166 to a second side housing 167 of the rear wheel mount 136. A rear wheel axle 155 can extend from the first side housing 166 to the second side housing 167. In some embodiments, the rear wheel axle 155 is coupled with the first side housing 166 and/or the second side housing 167. In some embodiments, the rear wheel axle 155 is fixed to the first side housing 166 at a first end. In some embodiments, the rear wheel axle 155 is removably coupled with the second side housing 167.

As shown in FIGS. 13A-14B, the first side housing 166 can be coupled with the gear assembly housing 156 at a first side. In some embodiments, the first side housing 166 can be coupled with the rear wheel axle 155. In some embodiments, the first side housing 166 is generally U-shaped. In some embodiments, the first side housing 166 is generally L-shaped. As shown, the first side housing 166 can include a first portion 166a, a second portion 166b, and/or a third portion 166c. In some embodiments, the first portion 166a can extend downwardly relative to the deck 102. In some embodiments, the first portion 166a is approximately perpendicular to the rear wheel axle 155. In some embodiments, the first portion 166a extends from the first side of the rear wheel assembly housing beyond an outer diameter of the rear wheel 134 when assembled. In some embodiments, the second portion 166b extends from an end of the first portion 166a. The second portion 166b can be integrally formed with the first portion 166a. In some embodiments, the second portion 166b extends approximately horizontal relative to the first portion 166a. For example, in some embodiments, the second portion 166b extend from the first portion 166a at approximately a 90 degree angle. In some embodiments, the second portion 166b is substantially parallel to a top surface of the deck 102. The second portion can extend from the first portion 166a positioned on one side of the rear wheel 134 beyond the other side of the rear wheel 134.

In some embodiments, the third portion 166c extends from the second portion 166b. The third portion 166c can extend at approximately a 90 degree angle from the second portion 166b. In some embodiments, the third portion 166c extends from the second portion 166b at another angle, such as 60 degrees, 70 degrees, or 80 degrees or more. In some embodiments, the third portion 166c is approximately parallel to the first portion 166a. For example, the third portion 166c can be approximately perpendicular to a longitudinal axis of the vehicle 100. As shown, the third portion 166c may extend upwardly from the second portion 166b by a length that is less than a length of the first portion 166a. In some embodiments, the third portion 166c extends upwardly to a vertical position just below an outer circumference of the rear wheel 134. In some embodiments, the third portion 166c extends upwardly towards the deck 152 such that at least a portion of the third portion 166c extends upwardly over at least a portion of the rear wheel 134.

The second side housing 167 can be removably coupled to at least a portion of the first side housing 166 to surround the rear wheel 134. As shown, at least a portion of the second side housing 167 can couple with at least the third portion 166c of the first side housing 166. In some embodiments, the second side housing 167 can include a slot to slide over the third portion 166c. In some embodiments, the second side housing 167 can engage the third portion 166c by a snap-fit configuration, mechanical fastener, or other coupling mechanism. In some embodiments, the second side housing 167 can include a hole configured to receive at least a portion of the rear wheel axle 155.

The rearward housing portion 132 can include the slot 163. The slot 163 can receive at least a portion of the rear wheel assembly 130. In some embodiments, the rear wheel assembly 130 can be secured to the deck through the slot 163 such that at least a portion of the rear wheel assembly extends through the slot 163.

FIGS. 13A-13B illustrate an embodiment of the rear wheel assembly 130 in a first position, such as a neutral position. As shown, the first side housing 166 can be positioned adjacent a first side of the slot 163. In some embodiments, the first side housing 166 can be fixed to the first side of the slot 163. In some embodiments, the first side housing 166 can be configured to remain in the first position. In the first position, as shown, the second side housing 167 can be coupled with the first side housing 166. In some embodiments, in the first position, the shaft 159 and/or axle 155 is received in the hole in the second side housing 167. The first side housing 166 can be positioned offset from a second side of the slot 163. The first side housing 166 can be positioned flush with the first side of the slot 163. In some embodiments, the second side housing 167 can be positioned offset from the second side of the slot 163 such that the second side housing 167 is spaced apart from the first side of the slot 163 in the neutral position.

FIGS. 14A-14B illustrate an embodiment of the rear wheel assembly 130 in a second position. As shown in FIG. 14A, the second side housing 167 has been decoupled from or otherwise disengaged from the first side housing 166. When the second side housing 167 disengages from the first side housing 166, the second side housing 167 can translate laterally along the slot 163 to expose a second end of the rear wheel axle 155. In some embodiments, the second side housing 167 is positioned adjacent the second side of the slot 163 in the second position.

Such configurations can allow the rear wheel 134 to be removed and/or replaced. When the vehicle is used for a certain amount of time, the rear wheel 134 may become damaged, and/or begin to wear. The rear wheel mount 136 can beneficially allow the rear wheel to be accessed. In some embodiments, such configurations can allow the rear wheel 134 to be easily removed and/or replaced. In some embodiments, various rear wheels 134 having various shapes, sizes, and/or colors can be implemented in the vehicle 100. The configurations described herein can advantageously accommodate rear wheels 134 having various shapes, sizes, and/or colors. For example, a user may want to change a rear wheel 134 having one color to a rear wheel having another color. The configurations described herein allow the user to easily remove and/or replace the rear wheel 134. Once the rear wheel 134 is replaced, the second side housing 167 can translate laterally along the slot 163 towards the first side housing 166 and engage with the first side housing 166 to secure the rear wheel assembly 130.

Motor and Throttle Assembly.

In some embodiments, the vehicle 100 includes a control mechanism, such as a wireless throttle remote assembly. The wireless throttle remote assembly 135 can include a throttle that can be toggled by the user to increase or decrease the speed of the motor 134 to increase or decrease the speed of the vehicle 100. In some embodiments, the throttle assembly can be wireless; however, in other embodiments, the throttle assembly 135 is wired to a motor and/or a battery.

In some embodiments, the throttle assembly 135 may be connected to a braking assembly through a wireless and/or a mechanical connection to slow or stop the vehicle 100. In some embodiments, the vehicle 100 comprises a braking button, switch, lever, or other actuator available to the hand or the foot of the user while the user operates the vehicle. For example, as shown in FIG. 3, the support surface 104 can include a brake aperture 190 to receive a braking actuator 192. Depressing the braking actuator can slow or stop the front wheel, which can slow or stop the vehicle 100. In some embodiments, the braking functionality is provided by the motor. In some variants, the brake comprises a drum brake, disk brake, caliper brake, or otherwise. In some embodiments, the brake is positioned at the forward portion 110 and/or the rearward portion 112. In some embodiments, the vehicle 100 includes a brake actuator 192 positioned near the front and/or rear wheel. For example, the brake can be configured to cause the front wheel and/or the rear wheel to slow down or stop when the brake actuator 192 is actuated.

In some embodiments, the motor can be controlled by a throttle actuator 194a that can be depressed through a throttle aperture 194 in the deck 102. For example, a user can depress the throttle positioned within the throttle aperture to provide instructions to the controller to supply power to the motor. For example, the throttle actuator 194a can be depressed. When the throttle actuator 194a is depressed through the throttle aperture 194, the motor is configured to instruct the controller to supply power to the motor. In some embodiments, the throttle actuator 194a can be positioned in the rearward portion of the vehicle 100. In some embodiments, the throttle 194a can be configured to instruct the controller to supply power to the motor and/or the rear wheel.

In some embodiments, the motor 134 can be controlled by a wired or wireless remote control. The remote control can include a transmitter and a trigger or other suitable control(s). Movement of the trigger and/or the amount of movement of the trigger can be detected, such as by a sensor in the remote control. This information can be used (e.g., by a processor or in the remote control or on the vehicle 100) to determine an amount of motive power to be provided by the motor. In some embodiments, the transmitter can transmit a signal corresponding to the amount of trigger movement and a receiver on the vehicle 100 can receive the signal, which can be used to control the motor. In some embodiments, the trigger comprises an accelerator to control motive power provided by the motor. Although a “pistol-grip” style of remote control can be used, other configurations are contemplated as well, such as a button, switch, joystick, toggle, slider, trackball, smartphone app, or otherwise. In some configurations, the remote control is the only element of the vehicle 100 that is controlled with a hand. For example, in some implementations, although the throttle can be controlled via remote control, the user can control all other aspects of the vehicle 100 with his or her feet in a manner similar to a normal or caster skateboard. In at least some configurations, the vehicle 100 may not include a handlebar or other hand support that is connected to the deck 102 or other portion of the vehicle 100.

In contrast to certain powered vehicles with controls on handlebars or other supports, the remote control can allow a user to move both of his or her hands during operation of the vehicle, while still being able to control locomotion of the vehicle. In some embodiments, the remote control can be configured to be held and operated by a single hand. In some embodiments, the remote control can facilitate user safety, such as by not restraining the user's hands to handlebars or other supports, and instead readily allowing the user to move his or her hands to catch the user in the case of a fall.

Some embodiments of the vehicle 100 includes at least one battery. In some embodiments, the battery can be mounted to the underside of the support surface 104 and/or positioned within the rearward housing portion 132. In some embodiments, the battery is insertable and/or removable from the housing portion 132. The battery may be any type of battery, such as a lithium ion rechargeable battery. For example, the battery can have an approximate 1.5-2.5 hour discharge time.

In various embodiments, the controller can receive a signal from the throttle assembly. For example, the controller can receive a signal indicative of the amount of speed and/or power to apply to the rear wheel 134. The controller can provide two-way or one-way transmission to the motor 132. For example, the controller can instruct the motor to drive the wheel 134 in response to and/or consistent with the signal from the throttle assembly. While control of the vehicle 100 can be wireless via the wireless throttle assembly, some variants have wired connections to connect the throttle, brake, and on/off switch to the motor. Any wired or wireless protocol may be used.

Operation of the Vehicle

In operation, the user can place his or her feet generally on the front portion and rear portion of the deck 102. The user may rotate or tilt his or her body, shift his or her weight, and/or modify his or her foot positions to control the motion of the vehicle 100. For example, for steering, one side of the deck 102 can be tilted towards the ground to encourage a turn in that direction. In some configurations, the vehicle 100 can be operated as a flexible skateboard in that the user can cause, maintain, or increase locomotion of the vehicle 100 by causing the front and rear portions to be twisted or tilted relative to each other generally about a longitudinal axis of the deck 102.

In various embodiments, the rear wheel 134 can be used to accelerate or decelerate the vehicle. For example, the remote control can be used to send a signal to control (e.g., increase or decrease) an amount of power provided to the rear wheel by the motor and/or to initiate a braking action. The user can still control steering of the vehicle 100 by rotating his or her body, or by shifting his or her weight and/or foot position, on the deck 102 as discussed above.

In contrast to a conventional skateboard, movement of the vehicle 100 can be provided without the user needing to move his or her feet. For example, from a stopped position, the user can place his or her feet on the deck 102 and can actuate the trigger on the remote, thereby causing the motor to drive the rear wheel, which in turn propels the vehicle. In some embodiments, the user does not need to lift a foot off the deck and push off the ground in order to provide locomotion. In certain variants, the user does not need to move his or her feet (e.g., to cause the forward and rearward portions to move relative to one another) in order to provide locomotion.

In some embodiments, the auxiliary wheels 182 can be used to accelerate or decelerate the vehicle in addition to and/or instead of the rear wheel 134. For example, the remote control can be used to send a signal to control (e.g., increase or decrease) an amount of power provided to the auxiliary wheels 182 by the motor and/or to initiate a braking action. The user can still control steering of the vehicle 100 by rotating his or her body, or by shifting his or her weight and/or foot position, on the deck 102 as discussed above. In some embodiments, the auxiliary wheels 182 begin to spin when the wheels 182 touch the ground and the vehicle is already in motion. In some embodiments, the auxiliary wheels 182 can begin to rotate before the wheels 182 touch the ground. For example, in some embodiments, the auxiliary wheels 182 are powered, such as by the motor 152.

In some embodiments, by shifting his or her weight and/or foot position, the user can tilt the vehicle 100 side-to-side and/or front-to-back. When the user tilts the vehicle, the vehicle 100 can be alternatively supported by one auxiliary wheel 182 or the other auxiliary wheel. For example, the auxiliary wheel 182 positioned beneath the side of the vehicle on which the user leans can contact the ground. In some such configurations, the opposite auxiliary wheel 182 can be lifted off the ground. In some embodiments, both of the auxiliary wheels 182 remain in contact with the ground as the user tilts the vehicle. In some embodiments, as the user tilts the vehicle, the auxiliary wheels 182 help to prevent or inhibit the user from falling off the vehicle in a forward and/or backwards direction. Thus, the auxiliary wheels 182 can help to stabilize the vehicle 100 when in use.
