AI Technical Summary
When the operator forgets to close the existing electronic lock, it may lead to vulnerabilities in the security system and easily lead to accidents.
A self-reset electronic lock is designed, including a shell, lock core, torsion spring, slider, contact piece and bottom plate. Through the coordination of the torsion spring and spring, the lock core can be automatically reset to a closed state without a man rotating the key and disconnecting the power supply.
When no one rotates the key, the lock core will automatically reset to the off state, keeping the power supply off, avoiding the power supply being turned on for a long time due to forgetting operation, and ensuring the reliability of the entire security system.
