Description

Technical Field

[0001] The present invention relates to the technical field of intelligent door locks, and in particular to a fully automatic overlord lock body. Background Art

[0002] Smart door locks are complex, fully automatic locks that differ from traditional mechanical locks, offering security, convenience, and advanced technology. In addition to mechanical locking and unlocking via a key and handle, they also utilize an intelligent motor for fully automatic locking and unlocking. Currently, most smart door locks utilize a primary lock tongue to lock the door. Existing unlocking fork assemblies only require actuating one set of lock tongues for both locking and unlocking. However, for doors requiring increased security, heavy-duty locks such as Overlord locks are often employed. These locks incorporate two sets of auxiliary lock tongues to enhance locking stability. This modification increases the lock's structural complexity, requiring a linkage mechanism to synchronize the primary and auxiliary lock tongues for simultaneous entry and exit. However, this linkage mechanism is complex and unstable, making it prone to jamming or poor feel, resulting in lock failure and forced replacement, increasing user costs and shortening the lock's lifespan.
