Abstract

The present invention is a system comprised of 4 subsystems that allow the riders to operate an electric bicycle. Called the Daymak Drive System (DDS), this invention includes a solar motorized wheel system, a solar throttle system, a solar pedal assist system (PAS), and a solar smart key. The motorized wheel system encases a 250W motor, a lithium battery pack, a wireless receiver, a battery management system board, and a controller. Furthermore, wireless transmitters located on the solar throttle system, solar pedal assist system and solar smart key relay signals to the wireless receiver in the motorized wheel to engage the motor. If the rider so chooses, switching the pedal assist "on" increases output power once the pedals are engaged. Similarly, rotating the throttle grip increases output from the 250W motor. All subsystems in the Daymak Drive System draw power from lithium battery packs that are rechargeable via outlet charger or trickle charging through mounted solar panel cells on each subsystem. The DDS provides three major benefits for the consumer: it is environmentally friendly, it helps consumers save cost by not having to rely on fossil fuels or power from the grid to operate the vehicle, and it provides peace of mind to the consumers since the self-charging feature constantly trickle charges the batteries. A consumer riding a DDS-powered electric bicycle for only 10 kilometers a day would never have to plug in and the charge the battery.

Description

TITLE
[001] Build a self-charging, wireless, solar, electric motorized wheel system for bicycles called Daymak Drive System (DDS).
TECHNICAL FIELD
[002] The present invention is an attachment for any bicycle comprising of: a solar, electric, motorized wheel, a solar throttle assembly, a solar pedal assist system, and a solar smart key.
BACKGROUND ART
[003] Despite the fact that bicycles are still the #1 means of transportation around the world, the electric bicycle industry is still struggling to find its footing within the market. There are four main factors that contribute to this barrier to entry for electric bicycles: the limited range per battery charge, cumbersome maintenance, high price range, and due to the average consumer's fear of technology.
[004] Existing technologies that try to remedy the problem address the needs of the consumer - there has been a shift towards conversion kits that offer the experience of an electric bicycle, and can be integrated with any standard frame bike. Currently, most electric bicycles provide an average range of 40 kilometers per battery charge - while seemingly ideal for intra-city means of transport, the cost (in comparison to a regular bicycle) outweighs its advantages. Most conversion kits in the market require an aptitude for electrical assembly, and other notable conversion kits only include a pedal assist system without a fully motorized throttle system. Moreover, many consumers are simply unwilling to invest in electric bicycles due to a lack of knowledge and electrical aptitude to install and maintain their initial investment.
[005] That being said, the present invention, called the Daymak Drive System (DDS), will address these issues. It will feature a fully solar, electric, and wireless motorized wheel, a solar, wireless throttle assembly, a solar, wireless pedal assist system, and a solar, "smart" remote ignition key that all communicate wirelessly, and can all be charged through a conventional plug-in charger if a quicker charge is necessary, or through trickle charging via the solar panel cells mounted on each system. A constant trickle charge from the mounted solar panel cells will not only prolong the battery, it will also extend the range for the electric bicycle. The design of DDS also ensures a quick and easy assembly. The process of replacing the front or rear wheel, and mounting the throttle and pedal assist system takes only a few minutes. Ultimately, the initial investment of a self-charging system will pay off in the long run - the consumer will benefit from reduced electricity cost by not needing to charge the bicycle, and they can enjoy the full benefits of an electric bicycle. If a consumer travels 10 kilometers on average per day, they will never have to charge their bicycle again.
DESCRIPTION OF INVENTION
[006] With reference to figures 1-4, the invention comprises of 4 systems that communicate with one another: the motorized wheel (figure 1), the throttle assembly (figure 2), the pedal assist system (PAS) (figure 3) and the smart key (figure 4). Before operation, each system must be installed as means of converting a regular bicycle into an electric bicycle.
[007] The motorized wheel can be installed as part of the rear wheel for any standard bicycle frame supporting a 26" tire. Spokes attach to the exterior of the motorized wheel housing unit (figure 1, 100.10.0), which then attaches to the tire rim. In terms of the assembly of the motorized wheel, it comprises of 11 separate parts: housing unit A (figure 1, 100.1.0), the gear (figure 1, 100.2.0), the 250W motor (figure 1, 100.3.0), the shock absorber (figure 1, 100.4.0), the battery pack (figure 1, 100.5.0), the battery management system board (BMS) (figure 1, 100.6.0), the controller (figure 1, 100.7.0), the wireless receiver (figure 1, 100.8.0), the solar panel housing (figure 1, 100.9.0), housing unit B (figure 1, 100.10.0), and the charging port (figure 1, 100.11.0)
[008] One aspect of the invention that enables the rider full control is the throttle assembly (figure 2, 200.0.0). The throttle assembly must be mounted on the handlebars in close proximity to the grips, so that the brake levers can be configured to trigger the wireless transmitter (figure 2, 200.10.0) inside the throttle housing (figure 2, 200.7.0). The actual throttle grip (figure 4, 200.1.0) enables the rider to engage 250W motor (figure 2, 100.3.0) by simply rotating it forward - this in turn, engages the wireless transmitter (figure 2, 200.10.0) inside the throttle housing (figure 4, 200.7.0), which then relays data to the wireless receiver (figure 2, 100.8.0) in the motorized wheel housing unit A (figure 2, 100.1.0), which then relays said data to the controller (figure 2, 100.7.0), which finally instructs the 250W motor (figure 2, 100.3.0) to increase output power. The two functions presently found on the throttle housing, the high/low speed switch (figure 2, 200.3.0) and the on/off switch for the PAS (figure 2, 200.4.0), follow the same process when relaying information from the wireless transmitter (figure 2, 200.10.0) inside the throttle housing (figure 2, 200.7.0), to the wireless receiver (figure 2, 100.8.0) inside the motorized wheel housing unit A (figure 2, 100.1.0), to the controller (figure 2, 100.7.0), and finally to the 250W motor (figure 2, 100.3.0). [009] Another aspect of the invention is the pedal assist system (PAS) (figure3, 300.0.0). The PAS must be mounted close to the pedals of the bicycle so that the crankset can be configured to trigger the wireless transmitter (figure 3, 300.3.0) inside the PAS housing unit (figure 3, 300.1.0), where the data is relayed to the wireless receiver (figure 3, 100.8.0) inside the motorized wheel housing unit A (figure 3, 100.1.0), which further relays the data to the controller (figure 3, 100.7.0), and finally relayed one more time to the 250W motor (figure 3, 100.3.0), which is the mechanism responsible for output power. The purpose of the PAS system is to increase output power in the 250W motor (figure 3, 100.3.0) if the rider begins to pedal the bicycle. While the wireless transmitter (figure 3, 300.3.0) inside the PAS housing unit (figure 4, 300.1.0) is always on, the rider can opt not to use the feature by either ensuring that the PAS on/off switch (figure 2, 200.4.0) on the throttle housing (figure 2, 200.7.0) is set to "off," or by simply not engaging the pedals.
[010] The last aspect of the present invention is the smart key. Acting as a remote control for the motorized wheel assembly (figure 4, 100.0.0), it enables the rider to turn on or off the 250W motor (figure 4, 100.3.0) inside the motorized wheel housing unit A (figure 4, 100.1.0). With a simple press of a button, the rider can choose to turn on or off the 250W motor (figure 4, 100.3.0) completely.
