Description

Technical Field

[0001] This utility model belongs to the field of padlock technology, and specifically refers to an intelligent padlock. Background Technology

[0002] A padlock has a U-shaped shank that can extend, retract, and rotate relative to the lock body. The shank engages with the latch / ring of the object being locked to complete the locking process. Opening a padlock generally requires a matching key.

[0003] Electronic padlocks rely on a motor to drive internal moving parts to lock the clasp. When the moving parts are released, the clasp can freely extend, retract, and rotate to unlock. However, current electronic padlocks have relatively limited functionality and are prone to issues such as the motor not rotating sufficiently, preventing them from locking or unlocking, posing a safety hazard.
