Description

Technical Field

[0001] The utility model relates to the technical field of intelligent door locks, and in particular to an unlocking structure of an intelligent glass door lock. Background Art

[0002] With the rapid development of smart home technology, smart door locks, as an important part of home security, are increasingly valued for their safety, convenience and reliability. Most smart door locks on the market currently integrate multiple electronic unlocking methods such as password input, fingerprint recognition, and RFID card reading, which greatly enriches the user experience.

[0003] However, in the prior art, some glass door locks often have a large gap between the main lock body and the secondary lock body in the closed state when locked. This results in that when the glass door is pushed by external force, the gap in the door is large enough for fingers to easily penetrate and contact the mechanical structure inside the lock, which may be unlocked by improper operation, posing a potential safety risk.

[0004] Therefore, it is imperative to redesign the unlocking structure of a smart glass door lock. Utility Model Content
