Abstract

The invention relates to a drive, code discrimination and coupling integration micro electromechanical code lock, comprising a shell, a pawl, a ratchet wheel, photoelectric inductors, an upper stator,a lower stator, spindles and counter-intervention meshing gears, wherein the pawl and the ratchet wheel are arranged at the outer side of the uppermost surface of the shell, the ratchet wheel is installed on the spindles, the pawl is installed on the shell and is embedded into a tooth groove of the ratchet wheel, two spindles penetrate through the code lock, the lower stator, the counter-intervention meshing gears and the upper stator are arranged in the shell and are sequentially connected in series to the spindles, and the photoelectric inductors are respectively arranged in the shell corresponding to the positions of the counter-intervention meshing gears. By using a drive, code discrimination and coupling integration micro electromechanical structure, the invention integrates three parts of a drive, a code discrimination mechanism and a coupler into one part, therefore, the structure of code lock dynamics is reduced, the installation is convenient, and the reliability is higher.

Description

technical field [0001] The invention relates to a micro-electromechanical combination lock in the field of micro-electromechanical technology, in particular to a micro-electromechanical combination lock integrated with driving, identification and coupling. Background technique [0002] MEMS password lock, also known as MEMS strong chain, is an energy gating or switching mechanism used in critical systems (high consequence system, referring to systems that cause major catastrophic consequences due to accidents or man-made sabotage). With the development of technology and computer technology, its mechanical structure is getting smaller and smaller, and its structure is becoming more and more complex. It can be widely used in defense fields such as weapons and equipment, ammunition depots, and confidential departments. It can also be used in government agencies, banks, Information security in financial and other sectors. [0003] After searching the literature of the prior art...
