A multi-physics de-protection mems security device

Abstract

A multi-physical field deprotection MEMS security device, comprising a substrate layer, a security mechanism layer and a cover layer, the three layers are assembled into one; the acceleration chamber of the substrate layer and the booster of the cover layer are in a fixed alignment state, and the security mechanism The detonating charge in the layer is filled in the metal partition, and the detonating charge is not in alignment with the acceleration chamber and the booster charge in a safe state; the mass block of the security mechanism layer is in the recoil mechanism of the substrate layer. The ball lock of the substrate and the cover plate layer A stainless steel ball is placed between the mechanism slots and on the upper surface of the mass block; in a safe state, the separator is restricted by the electrothermal actuator and the recoil mechanism, the top of the acceleration chamber is covered by a metal separator, and the detonating charge and booster charge are out of alignment state, the flyer cannot be detonated; in the release state, the acceleration chamber, the detonator and the booster are on the same axis, and the flyer detonates the detonator and the booster to complete the transfer of the detonation sequence energy; the invention has a multi-physical field Release protection, high explosion-proof strength, high overload resistance, intelligent control and other characteristics.

Description

technical field [0001] The present invention relates to the technical field of security devices, in particular to a multi-physical field de-security MEMS security device. Background technique [0002] The security device is the core component that controls the transmission of explosive power in the weapon equipment system, and is an important component of weapons and ammunition. In the safe state, it can block the transmission of unexpected detonation energy, and in the released state, it can make the detonation sequence energy smoothly. transfer. The security device usually adopts a movable partition structure to control the state of weapons and ammunition, and its performance affects the safety and reliability of the entire weapon equipment system. Therefore, combining the advantages of MEMS technology, the development of a new generation of MEMS security device technology with the characteristics of driving intelligence, structure miniaturization and serial integration h...

AI Technical Summary

Problems solved by technology

The inertial drive relies on the environmental force information during the flight of the ammunition to judge the release conditions of the security device, which has high reliability and safety, but it is a passive release with a low degree of intelligence; although the electrothermal drive and electromagnetic drive methods Active intelligent control of the state of the security device can be realized through electrical signals, but its safety and reliability are relatively lower than those of inertial drives

[0004] It is difficult for existing MEMS security devices to improve their intelligence while ensuring their high safety and reliability
