The principle of a semi-automatic smart lock is primarily based on the linkage between its unlocking mechanism and internal structure, combining electronic identification and mechanical operation to achieve secure unlocking.
Unlocking Mechanism: Combination of Electronic Identification and Mechanical Operation
The core of a semi-automatic smart lock lies in combining electronic identification technology (such as fingerprints, passwords, IC cards, and mobile apps) with the mechanical operation of traditional mechanical locks. After user authentication via a semiconductor or optical fingerprint sensor (response speed ≤ 0.3 seconds), manual rotation of the door handle is required to trigger unlocking. This design retains the reliability of mechanical locks while supporting multiple unlocking methods, including fingerprints, passwords, IC cards, remote control via mobile apps, and even retaining a mechanical key as an emergency backup. For example, when fingerprint recognition is successful, the system only releases the electronic lock; the user still needs to physically unlock the door by rotating the handle, avoiding situations where the door cannot be opened due to electronic malfunction.
