Bi-directional driving micro-electro-mechanical system (MEMS) security device

Abstract

A bi-directional driving micro-electro-mechanical system (MEMS) security device comprises a cover plate layer and a security device layer which are stuck by applying glue, after assembly, transverse heat insulation grooves of the cover plate layer and transverse heat insulation cavities of the security device layer are located on the two sides of a transverse V-shaped electric heating actuator ofthe security device layer separately, a silicon separation plate of the security device layer is located in a slideway observation window of the cover plate layer, and a silicon through hole and a silicon acceleration boring through hole of the security device layer are laid coaxially. The overall structure of the security device layer is of axial symmetry layout, a movable separation plate is arranged in the center of the security device layer and disposed in a limiting slideway, the two ends of the movable separation plate are connected with the security device layer through a T-shaped beam,and four sets of driving units are symmetrically arranged around the movable separation plate. After fabrication is completed, the T-shaped beam is broken by external force, and the movable separation plate is limited only by the driving units. The silicon separation plate is driven in dual directions, mutual conversion of working states of the bi-directional driving MEMS security device is realized, and the bi-directional driving MEMS security device has the characteristics of high strength, overload resistance, large displacement output, structure self-locking and the like.

Description

technical field [0001] The invention relates to the technical field of security devices, in particular to a bidirectional drive MEMS security device. Background technique [0002] The safety device is an important part of the detonation system, and its main function is to realize the safety and reliable release control of the detonation sequence. In order to ensure the safety of one's own side, it is required that the ignition procedure of the detonation transfer sequence can be started normally under certain conditions. Therefore, when designing related devices, it is necessary to introduce a partition mechanism to realize the control of detonation energy transfer. [0003] Conventional security devices are mostly driven by inertia or pyrotechnics. Through their own inertial force or the thrust generated by the priming charge, the diaphragm will produce a specific displacement and deformation, thereby realizing the change of the state of the security device.

Problems solved by technology

[0003] Conventional security devices are mostly driven by inertia or pyrotechnics. Through their own inertial force or the thrust generated by the priming charge, the diaphragm will produce a specific displacement and deformation, thereby realizing the change of the state of the security device. This driving method can only achieve a single device state. direction change, that is, from a safe state to an unsecured state. For smart weapons with repeated state and two-way driving requirements, the traditional structural method will not be able to meet the relevant requirements.
