Electromechanical lock

摘要

An electromechanical lock and its operation method is disclosed. The method includes: reading data from an external source; matching the data against a predetermined criterion; providing a fulcrum provided that the data matches the predetermined criterion; holding the lock by a locking pin, when engaged, in a locked state, and, when disengaged, in a mechanically openable state; and if the fulcrum is provided, levering mechanical power with the fulcrum to the locking pin to mechanically disengage the locking pin.

主权项

1. An electromechanical lock, comprising:
an electronic circuit configured to read data from an external source, and match the data against a predetermined criterion; a support configured to move by electric power to a fulcrum position provided that the data matches the predetermined criterion; a locking pin configured to hold the lock, when engaged, in a locked state, and, when disengaged, in a mechanically openable state; a lever coupled with the locking pin and having two distal ends, the lever being configured to receive mechanical power provided that the data matches the predetermined criterion such that the lever is supported by the support at the fulcrum position and one of the distal ends of the lever that is farther to the support is pushed down by the mechanical power, thereby mechanically disengaging the locking pin provided that the support is in the fulcrum position; and an electric generator configured to generate the electric power from the mechanical power, wherein the electric generator is further configured to generate the electric power and feed the electric power to the electronic circuit such that the support is moved to the fulcrum position by the electric power.
