Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority from Australian Patent Application No. 2017904121, filed Oct. 12, 2017.

FIELD

The present invention relates to controllers for electric skateboards.

BACKGROUND

A variety of controllers have been proposed for electric skateboards. Existing controllers typically comprise multiple buttons and switches positioned on a handheld housing to be accessed and actuated by fingers and/or thumbs of a hand of a user.
Existing controllers for electric skateboards suffer from various drawbacks. They are typically unergonomic because their multiple buttons, switches and thumb wheels that cannot be readily accessed or actuated by a user's fingers or thumb. In addition, existing controllers do not comfortably or intuitively translate hand movements into corresponding trigger control inputs for high performance electric skateboards. As a result, existing controllers fail to logically or safely map hand movements to the different operations and functionalities of high performance electric skateboards, such as acceleration, braking, speed control by thumb control, etc.
In this context, there is a need for safe, comfortable and intuitive controllers for high performance electric skateboards.

DESCRIPTION OF EMBODIMENTS

Referring to FIG. 1, a controller 10 for an electric skateboard (not shown) according to an embodiment of the present invention may generally comprise a pistol-grip housing 12 configured to fit in a palm of a hand (not shown) of a user (not shown) of the electric skateboard. An accelerator trigger 14 may be positioned on an upper front portion of the pistol-grip housing 12, and may be configured to be actuated by a first finger of the hand when the pistol-grip housing 12 is gripped. In use, actuation of the accelerator trigger 14 may progressively accelerate the electric skateboard. A brake trigger 16 may be positioned on an upper rear portion of the pistol-grip housing 12, and may be configured to be actuated by a thumb of the hand when the pistol-grip housing is gripped. In use, actuation of the brake trigger 16 may progressively brake the electric skateboard.
A display screen 18 may be positioned on a front upper portion of the pistol-grip housing 12 above the accelerator trigger 14 and forwardly of the brake trigger 16. The display screen 18 may be configured to be viewed by the user when the pistol-grip housing 12 is gripped. For example, the display screen 18 may be inclined upwardly from the brake trigger 16 from its rear to its front ends toward a head and eyes of the user. In use, the display screen 18 may display parameters relating to the operating state, set up and performance of the electric skateboard, such as speed, distance, battery life, gear ratios, speed settings and skateboard electrical diagnostics etc.
The controller 10 may further comprise a deadman safety switch 20 positioned on a middle front portion of the pistol-grip housing below the accelerator trigger 14, and configured to be actuated by second, third and little fingers of the hand when the pistol-grip housing is gripped. In use, releasing the deadman safety switch 20 may cease the operation of the electric skateboard, and will not allow control the electric skateboard unless it is pressed in by the second, third and little fingers of the hand when the pistol-grip housing 12 is gripped. A micro-USB socket 22 may be positioned on a lower front portion of the pistol-grip housing 12 below the deadman safety switch 20, and may be configured to receive a micro-USB plug (not shown).
Referring to FIGS. 2 and 3, the controller 10 may further comprise first and second speed control buttons 24, 26 positioned on a middle rear portion of the pistol-grip housing 12 below the brake trigger 16. The first and second speed control buttons 24, 26 may be configured to be actuated by a thumb of the hand when the pistol-grip housing 12 is gripped. In use, the first and second speed control buttons 24, 26 may selectively change the speed of the electric skateboard between two predetermined speed settings, and may also allow the user to access the different user modes to best control the electric skateboard. The controller 10 may further comprise an ON/OFF button 28 positioned on a lower rear portion of the of the pistol-grip housing 12 below the first and second speed control buttons 24, 26. The ON/OFF button 28 may be illuminated by LEDs 30 configured to indicate an ON operating state of the controller 10.
Referring to FIG. 4, the controller 10 may further comprise a rechargeable battery 32 positioned in the pistol-grip housing 12. The micro-USB socket 22 may be configured to charge the rechargeable battery 32 via a micro-USB plug (not shown). The controller 10 may further comprise an electronics assembly 34 positioned in the pistol-grip housing 12 and connected to each of the rechargeable battery 32, accelerator trigger 14, brake trigger 16, display screen 18, first and second speed control buttons 24, 26, deadman safety switch 20, and ON/OFF button 28. The electronics assembly 34 of the controller 10 may be configured to wirelessly communicate with an electronic control module (not shown) of the electric skateboard, and to map or translate user inputs via the controller 10 to the different operations and functionalities of the electric skateboard.
A removable screen cover 36 may be provided for the display screen 18, and a removable USB cover 38 may be provided for the micro-USB socket 22. Each of the accelerator trigger 14 and the brake trigger 16 may be mounted in the pistol-grip housing 12 via a spring 40 and a pin 42.
As best seen in FIG. 5, the pistol-grip housing 12 may comprise first and second moulded plastic shells 44, 46. First and second grip portions 48, 50 may be respectively over moulded over portions of the first and second moulded plastic shells 36, 38.
The accelerator trigger 14 and brake trigger 16 may, for example, each comprise a magnetic Hall effect sensor. The first and second speed control buttons 24, 26, deadman safety switch 20, and ON/OFF button 28 may, for example, each comprise a tact switch. The display screen 18 may, for example, comprise a TFT-LCD screen.
Embodiments of the present invention provide a safe, comfortable and intuitive controller that is useful for remotely controlling high performance electric skateboards.
