Definitions

  • the present disclosure relates to a personal electric trike; and more particularly to a compact electric trike that can safely maneuver tight environments and efficiently transport cargo.
  • the transportation sector is one of the largest generators of greenhouse gas emissions and poses one of the largest environmental challenges to the planet. As such, there is a wide felt need for more sustainable means of transport. Many current forms of more sustainable transport, such as electric or hybrid cars, are inefficient for transporting individuals and relatively small amounts of cargo.
  • Cargo bikes are generally bigger and heavier than standard road or mountain bikes and typically include a basket, bag, or storage compartment.
  • Cargo bikes present a significant physical strain on a user and can be unreasonable for long distances or heavy cargo. Further, bikes require forward motion to help balance, making navigating urban areas where frequent stopping and starting is required challenging.
  • Current electric trikes remove or supplement the need to pedal but still present many inefficiencies. Particularly, a broader wheelbase of many electrical trikes makes turning more difficult, losing out on the maneuverability provided by traditional bikes. This lack of control is amplified for electric trikes that place storage means between two wheels. Additionally, many electrical trikes have limited or no storage capacity for moving cargo and have high loading points to which the cargo must be raised. Furthermore, electric vehicles that load from the back can make it difficult for a user to monitor the security and status of the cargo.
  • Alternative forms of personal electric transport such as electric mopeds, can be cost prohibitive and fail to address aforementioned storage concerns.
  • the present disclosure is directed to a personal electric trike configured to provide enhanced maneuverability and transport of cargo.
  • Embodiments are disclosed of a personal electric trike that can provide enhanced maneuverability by incorporating tilting front wheels and a narrow profile.
  • Embodiments of the personal electric trike provides an environmentally-friendly means of transporting cargo via a low to the ground platform.
  • the personal electric trike comprises a platform body, a back wheel, two front wheels, a seat base, a seat, a steering base, a steering mechanism, an electric motor and a dividing wall.
  • the platform body connects the back wheel to the front wheels and extends a substantial length of the electric trike.
  • the seat base, the steering base, and the dividing wall are arranged proximal to the electrically powered back wheel and protrude from platform body.
  • a portion of the platform body between the dividing wall and the front wheels is configured for the placement of cargo.
  • the platform body includes an undercarriage compartment housing a battery, electrical control systems, at least a portion of a tilt locking mechanism, and a steering system.
  • the front wheels are coupled to the platform body via a tilting mechanism.
  • the tilting mechanism provides a tilting arrangement configured to allow the front wheels to tilt in the direction of a turn.
  • the tilting mechanism can include a tilt lock to prevent tilting when the electric trike is stationary.
  • An electric trike including an electric motor that activates the trike, a platform body, a steering mechanism, a wheel, and a pair of wheels.
  • the platform body has a first end and a second end.
  • the platform body includes an electric control system coupled to the electric motor and a battery that stores electric power to supply the electric motor.
  • the steering mechanism is coupled to the platform body.
  • the wheel is coupled to the first end of the platform body via a suspension mechanism.
  • the pair of wheels are positioned adjacent and coupled to the second end of the platform body via a tilting mechanism such that the platform body does not extend between the pair of wheels.
  • the tilting mechanism is configured to allow the pair of wheels to tilt in the direction of a turn.

  • This functionality is possible as the tilt mechanism can balance some or all of the roll moment caused by centripetal acceleration with an opposite roll moment caused by gravity, similar to bicycles and motorcycles.
  • the ability to balance the movement caused by lateral acceleration in a turn, due to high speed, tight radius, or both, with a counter moment caused by gravity, means the electric trike does not have to be low, wide, or slow.
  • stability of the electric trike does not depend on the axle track, so the center of mass does not have to be located near the wide axle and instead can be located anywhere between the front and rear axle, increasing flexibility of how a user can load cargo onto the platform body.
  • the narrow profile supported by the tilting mechanism can result in reduced aerodynamic drag and increased fuel efficiency. Additionally, the narrow axle track means that the electric trike does not require as much clearance and may experience less aerodynamic drag because of a smaller cross-sectional area. Another benefit of the narrow profile is easier parking and more efficient storing the electric trike.
  • the electric trike facilitates cargo transportation via the platform body. Loading cargo onto the electric trike is made easier by the low profile of the platform body. Further, placement of cargo on the platform body in front of a user allows a user to easily monitor the status of the cargo and reduces the chance of theft when in transport. In embodiments with a seat, the high position of the seat gives a user an advantageous angle to both see the cargo and the terrain in front of the electric trike well and to easily mount and dismount.
  • the fully electric power of the electric trike removes the need for cumbersome pedals and can be used by a wider audience, including those with less physical capacity or limited ranges of motion.
  • Various embodiments of systems, devices, and methods have been described herein.
