Electronic lock

The patent replaces traditional mechanical key-based locking systems with an motorized unlocking mechanism that uses a pinion gear and rack system. This substitution eliminates the need for physical keys while providing enhanced security through controlled motor actuation and digital authorization methods.

The motorized unlocking mechanism serves multiple functions: it provides secure locking, controlled unlocking through digital authorization, and can be integrated with wireless power systems. The single mechanism handles both security and operational control functions that would otherwise require separate systems.

The patent introduces a wireless power transfer system as an intermediary between the power source and the lock mechanism. This intermediary uses inductive coupling to transfer energy without physical contact, reducing power consumption while enabling the lock to function autonomously. The system includes a power receiver in the lock and a transmitter that can be a mobile device or fixed infrastructure.

The lock mechanism is designed to power itself through wireless energy harvesting. The power receiver in the lock captures energy from the wireless field and stores it in a capacitor or battery, allowing the lock to operate independently without external wiring or frequent battery replacement. The system harvests power on-demand during unlocking operations.
