DETAILED DESCRIPTION OF THE DRAWINGS

(21) FIG. 1 illustrates a side view of an electric vehicle 10 in the form of a powered skateboard for use on a golf course. The vehicle 10 has a deck 100, front wheels 120, rear wheels 122, a frame 140, and a seat assembly 200. Underneath the deck 100, best seen in FIGS. 17 and 18, is a drive system 300 and an energy storage system in the form of a battery 302. In the illustrated embodiments, battery 302 includes a casing that houses a lithium battery. The casing and battery will be collectively referred to as battery 302 for the sake of convenience.

(22) Turning to FIGS. 2 and 3, a rear end portion of the vehicle 10 is shown which has the deck 100 with rear wheels 122 and rear wheel guards 122. In the illustrated embodiment the deck has a non-slip surface in the form of artificial grass. It will be appreciated that other non-slip surfaces could be utilised such as rubber. Between the artificial grass and the upper surface of the deck is a waterproof membrane to prevent ingress of water through any upper surfaces of the board.

(23) The deck 100 has cut-out portions 102 in which the rear wheels 122 are located. Similar cut-out portions 102 in the deck 100 are provided for the front wheels 120. Provided on an end of the deck 100 is a mount 104 for removably mounting components which will be discussed in further detail with reference to FIGS. 12 to 15.

(24) FIG. 4 shows a front portion of the vehicle 10 including a front portion of the deck 100, the front wheels 120, and front wheel guards 120. The front portion has the frame 140 which includes a support member in the form of a pole 142. The pole 142 is mounted to the deck 100 and extends substantially vertically when the deck is substantially horizontal. At a lower portion adjacent the pole 142 is a bucket holder 144 holding a bucket 144 and a beverage holder 146 holding a bottle 146. The bucket holder 144 and beverage holder 146 are disposed on a base portion of the support pole 142.

(25) At an upper end of the support pole 142 is an accessory holding portion including an accessory ring 150. As seen more clearly in FIG. 5, the support pole 142 and accessory ring 150 have a control panel 152, an umbrella holder 160, a score-card holder 162, a bell 168, and a remote holder 170.

(26) The control panel 152 has a power switch 154, indicator LEDs 156, and an auxiliary switch 158. All switches are waterproof with an IP67 rating. The indicator LEDs 156 are typically used to display remaining battery power and the auxiliary switch 158 is typically used to toggle lights. The score-card holder 162 includes a golf ball holding portion 164 and a tee holding portion 166. The remote holder 170 is illustrated in FIG. 5 without the remote and in FIG. 4 holding a wireless trigger operated remote 172. In a preferred embodiment the remote holder 170 is a holster (not shown). At an upper end of the support pole 142 is a knob 174 which can be held by an operator and used for steering the vehicle 10.

(27) FIG. 6 shows the front side of the support pole 142 at an upper end. Provided on the front side of the support pole 142 is a support bracket 180. The support bracket 180 is welded to the support pole 142 and has a fastener in the form of a strap 182 which has a releasable clip 184. The strap 182 is length adjustable and can be opened and closed using the clip 184. The support bracket 180 and strap 182 are used to secure an upper end of a golf bag (not shown) to the vehicle 10.

(28) FIG. 7 shows a base portion of the support pole 142. The base portion includes a base 186 with a raised flange 188 around its perimeter. The base 186, which is more clearly illustrated in FIG. 8, is used to support the weight of the golf bag (not shown) from below and the flange 188 is used to hold the bottom of the golf bag in place.

(29) Also shown in FIG. 7 is a hinge assembly 190 near the base of the support pole 142 which has a releasable locking mechanism 192 which rigidly holds the support pole 142 in the upright position and allows hinged movement of the support pole 142 about hinge assembly 190 when released.

(30) The support pole 142 can then be folded to a collapsed position, as shown in FIGS. 8 to 10, for compactness and transportation. With the support pole 142 folded the entire vehicle 10 can fit inside the luggage compartment of most road vehicles (e.g. cars). As seen most clearly in FIG. 10, an electrical cable 194 runs through the support pole 142 to provide power and communication to the control panel 152.

(31) FIG. 11 shows the front of the vehicle 10 including a reflector 196 and forward facing white LED lights 198. As seen most clearly in FIG. 11, the base 186 is raised from the deck 100, typically by approximately 50 mm, to allow an operator to put their foot under the base 186 when operating the vehicle 10.

(32) FIGS. 12 to 15 show the removable seat assembly 200 which can be mounted on the mount 104 shown in FIG. 2. The removable seat assembly 100 includes a mounting portion 202, shock absorbing legs 204, a seat 206, and a storage portion 208. The storage portion 208 can be used to store various items but, as shown in FIG. 14, in the illustrated embodiment it contains a thermally insulated cold box 210. The cold box 210 is sized to allow transportation of six refreshing beverages. FIG. 15 shows the mounting portion 202, which is a quick release mechanism for locking the seat assembly 200 to the mount 104 shown in FIG. 2.

(33) FIG. 16 is a lower front view of the vehicle 10 which shows a front axle 220 between the front wheels 120. FIG. 17 is a lower rear view of the vehicle 10 which shows rear axle 222 between the rear wheels 122. The front axle 220 is mounted to a front truck 224 and the rear axle 222 is mounted to a rear truck 226. Adjacent the front axle 220 are two stops 228 which limit turning of the vehicle 10 to ensure stability. The front has forward facing white LED lights 198 and the rear has rear facing red LED brake lights 230. Also visible in FIG. 17 is a drive belt guard 232.

(34) FIG. 18 illustrates an underside view of the vehicle 10 including the drive system 300 and battery 302. The battery is a lithium battery, preferably with a capacity of approximately 26 Ah, electrically connected to the drive system 300 by cable 304. The drive system 300, and in particular the battery 302, is designed to provide enough power to traverse 27 holes of a golf course. This allows for a typical 18 hole golf game to be played with additional power to spare. Drive system 300 includes an electric motor 306 and a power transfer system including a drive belt 308 (see FIG. 19) protected by the drive belt guard 232.

(35) Also located underneath the deck 100 is a wireless receiver 320 which wirelessly communicates with the remote 172. The remote 172 and wireless receiver 320 communicate over the 2.4 GHz unlicensed frequency band using digital communication protocols such as Bluetooth. This allows remotes and wireless receives to have unique identifiers and to be paired digitally to prevent interference when multiple remotes and vehicles 10 are operating in close proximity. The remote has a limited range to prevent inadvertent control of the vehicle from a large distance.

(36) FIG. 19 illustrates a close up of the drive belt 308 which mechanically connects a rotor 310 of the motor 306 with a drive portion of the rear axle 222 in the form of a sprocket 312. The rotor and sprocket have teeth that engage with corresponding teeth on the belt 308. A belt tensioning system is provided which includes two protruding members in the form of a lug 314 with an adjustable height roller 316. Each lug 314 is located such that the rollers 316 urge the drive belt 308 against the rotor 310 of the motor 306 and the sprocket 312 of the rear axle 222.

(37) In use, an operator of the vehicle 10 stands on the deck 100 and operates the wireless remote 172 to move forward and backward. The vehicle 10 is turned by the operator leaning to the left or right, typically by holding the knob 174 on the support pole 142 which not only assists the operator with stability but also provides greater turning power. The operator can also carry a load, such as a full size golf bag (not shown), which is secured on the vehicle 10. This provides the operator with an easy transportation system for themselves and their belongings, particularly on off-road terrain.

(38) In a golfing environment, the vehicle 10 provides a golf player with a quick and efficient transport system between holes and to their ball. As each player has their own vehicle they can all travel individually, such as to their own balls simultaneously, which reduces unnecessary waiting and travelling.

(39) The wheels 120, 122 have a wide high grip tread which provides the necessary traction in off-road environments, but also spreads the load evenly over a large area which has less impact on turf than a players feet.

(40) Should a vehicle 10 run out of power or break down, the collapsible nature of the vehicle 10 allows it to be easily transported without the need for a trailer or large vehicle. Although relatively heavy, the vehicle can be carried. Alternatively, it can be placed in the boot of a car. This advantageously allows players to have their own vehicle which is easily transported to or from the golf course.

(41) Although the invention has primarily been described as being electric, it will be appreciated that other forms of power could be used such as could be used, such as petrol, or the like.
