Detailed Description

Structural Features

1. Frame and Folding Mechanism:

   • The frame is constructed using lightweight, high-strength materials, such as aluminum alloy or carbon fiber, to reduce overall weight while maintaining structural robustness.
   • The foldable design consists of a primary joint located at the base of the handlebar stem, allowing the stem to collapse towards the deck. A secondary folding hinge system at the deck allows the scooter to further compact by reducing its length longitudinally.
   • Quick-release locking mechanisms ensure easy and secure transitions between folded and unfolded states without requiring tools.

2. Portability Design:

   • A carry handle is integrated into the frame or deck to facilitate transportation. Alternatively, the folded scooter can be rolled using small auxiliary wheels positioned at the rear end.

3. Deck and Wheels:

   • The deck is designed to be low-profile with a non-slip surface for both stability and user safety.
   • Wheels are durable, shock-absorbing, and tailored for urban pavements. A dual-suspension system (front and rear) ensures smooth operation on uneven terrain.

Propulsion and Power System

1. Electric Motor:

   • A high-efficiency brushless direct current (BLDC) motor is integrated into the rear wheel hub, minimizing moving parts and maximizing power transfer. Peak power output supports urban commuting at speeds of up to 25 km/h (typical regulatory limit for electric scooters).
   • Torque optimization allows for effective climbing of slopes typical in urban settings.

2. Battery System:

   • A rechargeable lithium-ion battery module is placed under the deck for optimal weight distribution and a low center of gravity. The battery supports a typical range of 20-30 km per charge depending on riding conditions.
   • The battery is replaceable to extend operational life and includes a fast-charging feature.

3. Energy Efficiency:

   • The scooter incorporates regenerative braking technology, enabling the motor to recover energy while decelerating, thereby increasing battery efficiency.

User Interface and Ergonomics

1. Control System:

   • The scooter features an intuitive handlebar-mounted control panel displaying speed, battery capacity, and ride mode.
   • Accelerator and brake levers are ergonomically positioned for one-handed operation.

2. Adjustable Components:

   • The handlebar height is adjustable to accommodate riders of varying heights.
   • Foldable handlebars further reduce the scooter's width, enhancing storage options.

3. Smart Connectivity:

   • A wireless IoT module enables connection to a dedicated smartphone app for advanced functionality:
     • GPS navigation for optimized routes.
     • Battery health diagnostics.
     • Anti-theft tracking via GPS.
     • Personalization of ride parameters, such as speed limits and acceleration profiles.

Safety Features

1. Lighting:

   • Integrated front LED headlight and rear taillight ensure visibility in low-light environments.
   • Side reflective strips and optional under-deck ambient lighting improve visibility to other commuters.

2. Braking System:

   • A dual-braking system combines a regenerative brake within the motor hub and a traditional mechanical disc brake on the rear wheel for reliable stopping power.
   • The braking design ensures a smooth and controlled deceleration, minimizing wear on components.

Claims

1. A foldable electric scooter, comprising:

   • A frame with an adjustable handlebar stem and deck, wherein the frame is constructed from lightweight, high-strength materials.
   • A dual-fold mechanism enabling compact transformation of the scooter for ease of portability and storage.
   • A rear-wheel hub motor providing electric propulsion, powered by a rechargeable lithium-ion battery module strategically placed under the deck to optimize balance and usability.

2. The foldable electric scooter of Claim 1, further comprising:

   • Integrated LED lighting, reflective surfaces, and redundant braking systems for enhanced user safety during operation.
   • An IoT module enabling wireless connectivity, enabling advanced functionalities such as battery monitoring, GPS tracking, ride customization, and anti-theft measures.

3. The foldable electric scooter of Claim 1, wherein the folding mechanism incorporates a quick-release locking system allowing seamless transitions between folded and unfolded states.

4. The foldable electric scooter of Claim 1, wherein the ergonomic design includes an adjustable handlebar height and a non-slip deck surface, accommodating a broad range of rider preferences and enhancing comfort during urban commuting.
