Abstract

Battery powered vehicle typically homologated for road use, but not exclusively, includes an electronic differential which controls independent rear in-wheel drive motors 1, allowing riding platform 2 to be located below the centre of the rear wheels, providing low centre of gravity and ergonomic user step-up from ground level, facilitating accurate 360 degree turning circle and stable, steep incline ascent without wheel spin or wheel scrub. To prevent flipping over backwards, or sideways on steeply angled surfaces the vehicle incorporates an anti-flip electronic orientation chip 3, which senses the angle the vehicle is being driven and which is programmed to reduce, or shut off, the power to both rear wheels either together, or independently working in conjunction with the motor controller 4. Other characteristics and features of the control system are disclosed.

Description

Battery powered trike The present invention relates to three-wheeled battery powered trikes. Battery powered vehicles of various sizes and designs are well known in the prior art. For example it is commonly known that when a three wheeled battery powered trike is powered only through the front wheel there are performance limitations when ascending a steep incline. The centre of gravity moves rearwards, the load is reduced on the front wheel and the front wheel is vulnerable to losing grip on the surface of travel. The likelihood of front wheel drive slippage is compounded, particularly on a wet surface, should a three wheeled trike be hitched up at the rear for towing a trailer.
It is also commonly known that in order for a three wheeled trike to be designed for stand-on riding and not sit-on riding a stand-on platform needs to be low enough to facilitate an acceptable step-up height for the rider. Accordingly, to eliminate or reduce the limitations of the aforesaid front wheel drive by, instead, having both rear wheels driven, the riding platform of a three-wheel vehicle needs to be high enough off the ground to clear the driven rear axle of a conventional drive system. However, in order to achieve the above, the axle clearance height of a stand-on platform must be higher than acceptable ergonomics allows.
To overcome these shortcomings in battery powered three-wheeled vehicles described above in accordance with aspects of the present invention there is provided a vehicle comprising, in a preferred embodiment; a three-wheeled battery powered vehicle having a front wheel steerable through a steering mechanism and a pair of rear wheels; the rear wheels being powered independently by battery powered motors mounted inside each wheel hub, facing towards each other, as controlled by a vehicle controller and a sensor coupled to the drive system to sense orientation of the vehicle.
The vehicle controller for the independent rear wheel drive may automatically adjust the power delivered to each rear wheel through an electronic differential ensuring that, when desired, a 360 degree turning circle can be achieved without front wheel scrub. In so doing a manoeuvre as described above, for example, the vehicle controller is programmed to ensure there is no wheel scrub of either of the two rear wheels.
In accordance with aspects of the present invention ergonomic acceptance of riding platform height is achieved through removing the need for a rear axle running between the two rear wheels under the riding platform, offering ergonomic step-up to the riding platform and ergonomic step-down from the riding platform in line with standard stair-riser heights common in domestic dwellings.
In accordance with aspects of the present invention it is preferred to mount two battery-powered motors inside the two rear wheels to facilitate lowering the centre of gravity of the three-wheeled battery powered trike thus enabling greater stability when in use and therefore, safety.
In accordance with aspects of the present invention there is located in the vehicle controller an orientation chip, commonly known as an anti-flip safety device, which continually senses the angle of travel of the three wheeled vehicle and is programmed to reduce power to each wheel independently as necessary and is also programmed to shut down one or both electric motors as necessary to prevent roll over in order to return the aforesaid vehicle to an acceptable angle of travel.
The invention will now be described solely by way of example and with reference to the accompanying drawings in which; Figure 1 shows a three quarter rear view of a three wheeled battery powered vehicle in accordance with aspects of the present invention.
Figure 2 shows a side view of a three wheeled battery powered vehicle in accordance with aspects of the present invention.
Figure 3 shows a front three quarter view of a three wheeled battery powered vehicle in accordance with aspects of the present invention.
Figure 4 shows an opposite front three quarter view of a three wheeled battery powered vehicle in accordance with aspects of the present invention.
Figure 5 shows a front elevation of a three wheeled battery powered vehicle in accordance with aspects of the present invention.
S Figure 6 shows a front three quarter view of a three wheeled battery powered vehicle in accordance with aspects of the present invention.
Figure 7 shows an underside plan of a three wheeled battery powered vehicle in accordance with aspects of the present invention.
Figure 8 shows an alternative rear three quarter view of a three wheeled battery powered vehicle in accordance with aspects of the present invention.
Figure 9 shows an end elevation of a three wheeled battery powered vehicle in accordance with aspects of the present invention.
In figure 1 a battery powered motor 1, is located inside the centre of each rear wheel facing inwards towards each other, negating the need for a rear drive live axle between the two rear wheels. Therefore, ride-on platform 2 is not restricted in height and in a preferred embodiment is positioned at an ergonomic height from the ground, to facilitate acceptable step-up and step-down by a vehicle user and to facilitate a low centre of gravity for more control over uneven terrain. Anti-flip device orientation chip 3 is programmed in conjunction with vehicle controller 4, which monitors and adjusts power, through human manipulation of a standard throttle twist grip as necessary, to independent rear wheel drives ensuring safe travel of the three-wheeled battery powered vehicle.
Figure 2 shows a side view of the three-wheeled battery powered vehicle with the body of the vehicle covering the perimeter of the rear wheels with wheel arches 5 and showing the depth of the body 6 below the centre axle of the rear wheels 1, in accordance with aspects of the present invention.
It will be appreciated by those skilled in the art that any number of combinations of the aforementioned features and/or those shown in the appended drawings provide clear advantages over the prior art and are therefore within the scope of the invention described.
herein.
