To provide a drive mechanism that has a reduced beginning time of ejection operation, a small size and a light weight, and is capable of a reliable ejection operation, as an ejection machine that is ejected at the time of emergency fall of a drone and ejects a parachute to be deployed.SOLUTION: A parachute ejection device includes: a pulling spring of which one end is connected to an ejection part of a parachute and the other end is connected to part of a first lever member; and a second lever member engaged with the first lever member and driven by a solenoid. The parachute ejection device releases the engagement between the first lever member and the second lever member with the driving of the solenoid and releases the tensile force of the pulling spring to activate the ejection part of the parachute.SELECTED DRAWING: Figure 1
【課題】ドローンの緊急落下時に射出し、開傘させるパラシュートを射出する射出機として、射出動作の開始時間が短く、かつ小型軽量で確実な射出動作が可能な駆動機構を提供することを目的とする。【解決手段】パラシュートの射出部に一端が接続され、他端が第1の梃子部材の一部に接続された引っ張りバネと、前記第1の梃子部材に係合され、ソレノイドで駆動される第2の梃子部材とを備え、前記ソレノイドの駆動にて前記第1の梃子部材と第2の梃子部材との係合を解除し、前記引っ張りバネの引っ張り力を開放して、前記パラシュートの射出部を起動させることを特徴とするパラシュート射出装置を提供する。【選択図】図1
