Description:BACKGROUND
[001] Field of the invention
[002] Embodiments of the present invention generally relate to an electric transportation and pertain specifically to a novel and advanced self-charging electric motor bike.
[003] Description of Related Art
[004] A self-charging electric motor bike is a mode of transportation that is outfitted with technology or systems that allow it to replace its own energy store, often an electric battery, while in motion or at rest. This concept is closely related to electric motor bikes (EVs), which may gather or produce energy in a variety of ways to enhance travel distance or fuel auxiliary functions.
[005] Some electric motor bikes utilize sunlight, and electricity instead of fuel such as the Toyota Prius, a hybrid marvel that harnesses regenerative braking to recapture energy during braking and deceleration, subsequently replenishing the battery. In the realm of electric motor bikes, the Tesla Model S stands out, benefiting from over-the-air updates that enhance its regenerative braking prowess, ensuring maximal energy recovery during coasting and braking. The Chevrolet Volt adopts an extended-range electric motor bike (E-REV) configuration, relying on regenerative braking for battery recharging, and seamlessly integrating a gasoline engine as a supplementary generator for prolonged journeys. Moreover, electric motor bikes like the Fisker Ocean and Hyundai Sonata Hybrid ingeniously integrate solar panels into their design, tapping into sunlight to replenish the battery and augment overall efficiency.
[006] The implementation of self-charging electric motor bike systems presents a range of benefits, yet it also introduces several intricate challenges. While these systems offer innovative ways to recapture and utilize energy, efficiency concerns may arise due to the inherent losses in energy conversion and storage processes. For instance, technologies like solar panels integrated into electric motor bikes might struggle to generate ample energy, especially under cloudy conditions. Moreover, the integration of self-charging technologies may lead to increased complexity and costs in electric motor bike design and manufacturing, potentially affecting affordability and maintenance. Infrastructure requirements, such as those needed for inductive charging or swappable batteries, may pose economic and logistical hurdles. Furthermore, considerations about the environmental impact of producing and disposing of components used in these systems add layers of complexity to their adoption.
[007] There is thus a need for a self-charging electric motor bike that gains power from their riding and lowers dependency on external charging sources.
SUMMARY
[008] Embodiments in accordance with the present invention provide a self-charging electric motor bike. The self-charging electric motor bike, introduces an inventive approach to harnessing kinetic energy for sustained operation. It encompasses a frame, housing an array of batteries including lithium ferro phosphate and lead acid variants. Moreover, the self-charging electric motor bike includes a dynamo, an inverter, and a charger. The sequence commences as the user inserts a key into the key knob and presses an ignition switch and initiates acceleration via the throttle. This triggers the dynamo to convert wheel motion into electrical energy, subsequently stored within batteries. This electrical output is converted to direct current (DC) power by the inverter, which charges the second battery via the charger. This DC power is then directed to the motor, where it is transformed into mechanical energy to propel the bike forward. This ingenious mechanism ensures a self-charging capability, offering a sustainable and efficient means of transportation by utilizing kinetic energy to power the electric motor bike throughout its operational lifespan.

[0036] FIG. 3 presents a comprehensive flowchart 300 illustrating the operational sequence of the self-charging electric motor bike 102. The operational steps encompass the following key actions:
[0037] Step 302: The user initiates the operation of the self-charging electric motor bike 102 by activating the fully charged first battery 206a through the ignition switch 204. Subsequently, starting the bike 102 with a key and accelerating sets in motion a sequence of events. These actions collectively initiate the electric motor bike 102's operational cycle, inducing the rotation of its wheels and the ensuing movement.
[0038] Step 304: The rotational movement of the wheels activates the dynamo 208, situated near the front wheel of the electric motor bike 102. A belt system efficiently transfers the rotational force from the spinning wheels to the dynamo 208. This mechanism harnesses the energy generated by the wheels' rotation, transmitting it through the belt to drive the dynamo 208.
[0039] Step 306: The spinning dynamo 208 initiates the generation of electricity. This electrical energy is then directed to be stored for future utilization in the third battery 206c and the fourth battery 206d. Notably, the third and fourth batteries 206c and 206d are specifically designed as lead acid batteries in this embodiment.
[0040] Step 308: The stored AC power is transformed into the suitable DC power format through the inverter 210. This conversion phase is crucial to ensure seamless compatibility with subsequent processes. The inverter 210 plays a pivotal role in facilitating the swift integration of electricity into the ensuing stages, ensuring optimal performance and seamless operation of the electric motor bike 102.
[0041] Step 310: The converted DC power is transmitted to the charger 212 via the intermediary role of the inverter 210. The charger 212's significance lies in its ability to expedite and facilitate efficient energy transmission. Acting as a conduit, the charger 212 ensures efficient channeling and preparation of the converted DC power for the forthcoming stages.
[0042] Step 312: The charger 212 then directs the received DC power to the second battery 206b. Functioning as a bridge between the inverter 210's DC power and the distinct requirements of the second battery 206b, the charger 212 prepares the received electricity for transmission. Subsequently, the second battery 206b serves as a conduit, transmitting the energy to power the motor 214. The motor 214 converts this DC power into mechanical energy.
[0043] Step 314: Employing a chain sprocket mechanism, the electric motor bike 102 transfers the mechanical energy generated by the motor 214 to the rear wheel. This mechanism translates the motor's rotational motion into forward movement, propelling the electric motor bike 102. The flowchart 300 then loops back to Step 304, maintaining activity until the user intervenes by utilizing the brakes to bring the electric motor bike 102 to a complete stop.
[0044] The operational scenario of the electric motor bike 102 unfolds with a systematic initiation, commencing as the user inserts the key into the key knob 202 and presses the ignition switch 204, activating the vehicle. Subsequently, manipulation of the throttle and engagement of the first battery 206a propel the electric motor bike 102 into motion. This acceleration sets the wheels 106a-106b into a rotational state, prompting kinetic energy transfer to the dynamo 208 through a meticulously designed belt system. The dynamo 208, functioning as a generator, converts mechanical energy into electrical energy, which is efficiently stored in the third and fourth batteries, 206c and 206d. The subsequent phases involve the conversion and utilization of this stored energy. The inverter 210 orchestrates a seamless transformation of alternating current (AC) power into direct current (DC) format, enabling compatibility with subsequent processes. Processed DC electricity is directed to the charger 212, a pivotal intermediary ensuring efficient energy transition. This processed energy then flows to the second battery 206b, the conduit to the motor 214. Here, electrical energy is converted into mechanical energy, seamlessly transferred through a precision chain and sprocket arrangement. This arrangement propels the electric motor bike 102 forward, effectively harnessing the motor's rotational energy for sustainable propulsion. This orchestrated interplay underscores the self-charging capability of the electric motor bike 102, ingeniously transforming kinetic energy into a potent propulsive force for efficient and sustainable forward movement.
