The invention relates to the field of unmanned aerial vehicle transportation and launching recovery, and discloses an automatic locking and unlocking mechanism for a lifting platform. The mechanism comprises an upper part and a lower part, the upper part comprises an embracing ring, a rotating shaft, a torsional spring and an outer frame, the two ends of the rotating shaft are fixed to the outer frame, the torsional spring sleeves the rotating shaft, and the embracing ring is opened towards the two sides around the rotating shaft under the torsional spring force of the torsional spring; the lower part comprises a limiting groove and a supporting seat, and the limiting groove is fixed on the supporting seat; and the upper part is connected with a tray of the lifting platform through the outer frame, and the lower part is connected with a bottom fixed platform of the lifting platform through a supporting seat. The locking mechanism is divided into the upper part and the lower part whichare respectively connected with the moving tray and the bottom fixed platform of the lifting platform; and the torsional spring and the limiting structure are used to make the upper part and the lowerpart complete contact and separation by lifting of the platform tray in order to realize closing and opening of the embracing ring, so the requirements for automatic locking and unlocking are met, anadditional automatic control mechanism is not needed, and cost is reduced.

    本发明涉及无人机运输及发射回收领域,公开了一种用于升降平台的可自动锁定与解锁机构。该机构包括上部分、下部分,上部分包括抱环、转轴、扭簧及外框,转轴两端固定在外框上,扭簧套转轴上,抱环在扭簧的扭簧力作用下绕转轴向两侧打开;下部分包括限位槽与支承座,限位槽固定支承座上;上部分通过外框与升降平台的托盘连接,下部分通过支承座与升降平台的底部固定平台连接。本发明将锁紧机构设置为上下两部分并分别与升降平台的运动托盘和底部固定平台连接,利用扭簧和限位结构,通过上下部分在平台托盘升降带动下完成的接触和分离,实现抱环的关闭和打开,从而满足自动锁定和解锁的需求,无需额外的自动控制机构,降低了成本。
