The invention relates to an undercarriage electromechanical locking and releasing mechanism which comprises a lock shell, a rocker arm, a connecting rod, a tension spring supporting column, a tension spring, a lock hook bolt, a lock hook and a servo actuator, the lock hook, the connecting rod and the rocker arm are connected through bolts to form a connecting rod mechanism, and the electromechanical servo actuator serves as a push rod to push the rocker arm in a locking mechanism system. Compared with an existing locking hook and locking key abutting mechanism, impact between parts of the mechanism is eliminated, serious abrasion generated when the mechanism bears large loads is avoided, the unlocking reliability of the mechanism under the large loads is improved, and the purposes of being small in size, light in weight, large in bearing capacity and high in reliability are achieved.

    本发明涉及一种起落架机电锁定释放机构,包括锁壳、摇臂、连杆、拉簧支柱、拉簧、锁钩螺栓、锁钩和伺服作动器,将锁钩、连杆和摇臂通过螺栓连接,组成连杆机构,并采用机电伺服作动器作为推杆,推动锁紧机构系统中的摇臂,与现有的锁钩、锁键抵顶的机构相比,消除了机构零件间的撞击,避免了机构在承受大载荷时产生的严重磨损,提升了机构在承受大载荷下的开锁可靠性,实现了体积小、重量轻、承载大、可靠性高的目的。
