An Electromagnetic Driven Black Box Throwing and Separating Mechanism

Abstract

The invention provides an electromagnetically driven black box throwing and separating mechanism, which includes an ejection assembly and an actuating assembly arranged on an adapter seat, the adapter seat is fixed on the aircraft body, and the ejection assembly is arranged at the center of the adapter seat. There are at least two groups of actuating components, and they are evenly arranged around the adapter seat. The actuating components press the periphery of the black box; the ejection components include disc spring mounting seats, limit sleeves, disc spring guide posts and disc springs. It includes direct-acting electromagnets, connectors, swing rods, ejector rods and rotating shafts. The direct-acting electromagnets are arranged on the outside of the swing rods. The swing rods are T-shaped. The straight part is installed on the adapter seat through the rotating shaft, the inclined part cooperates with the slope of the connector, and the horizontal part contacts the side of the push rod. When the direct-acting electromagnet is extended, the push rod limits the swing of the swing rod. The invention has a compact structure, can press the black box tightly when the aircraft is flying safely, and throws and ejects the black box quickly and reliably after the aircraft crashes.

Description

technical field [0001] The invention belongs to the field of aviation technology, and in particular relates to an electromagnetically driven black box throwing and separating mechanism. Background technique [0002] The "black box" is used to record the flight parameters and voice information before the plane crash. After the plane crashes, the information recorded by the black box can be used to trace the cause of the accident. Now, in order to reduce the difficulty of searching, the black box can be thrown away. Separate from the aircraft body in advance, especially in the deep sea environment, to avoid sinking into the seabed with the aircraft. However, most of the existing throwing mechanisms are driven by explosives. Explosives not only have high storage requirements and safety risks, but also the environment Humidity is sensitive, which reduces reliability, and fire attack products have the disadvantages of detonating and polluting the environment.

[0002] The "black box" is used to record the flight parameters and voice information before the plane crash. After the plane crashes, the information recorded by the black box can be used to trace the cause of the accident. Now, in order to reduce the difficulty of searching, the black box can be thrown away. Separate from the aircraft body in advance, especially in the deep sea environment, to avoid sinking into the seabed with the aircraft. However, most of the existing throwing mechanisms are driven by explosives. Explosives not only have high storage requirements and safety risks, but also the environment Humidity is sensitive, which reduces reliability, and fire attack products have the disadvantages of detonating and polluting the environment. The invention provides an electromagnetically driven throwing and separating mechanism, which has a simple structure, small installation space, long storage life, and safety. High, insensitive to ambient humidity and temperature, which can improve the reliability of throwing
