The invention belongs to the technical field of unmanned aerial vehicle structural design, and particularly relates to an unmanned aerial vehicle arm folding and locking mechanism and an unmanned aerial vehicle. The unmanned aerial vehicle arm folding and locking mechanism comprises a fixed vehicle arm and a movable vehicle arm, the fixed vehicle arm is fixedly arranged on the unmanned aerial vehicle body, and the movable vehicle arm is connected with the fixed vehicle arm through the folding and locking mechanism. The folding locking mechanism comprises a fixed base, a movable base, a rotating shaft and a buckle. When the movable arms and the fixed arms are butted and locked, the unmanned aerial vehicle arms are in an unfolded state; when the unmanned aerial vehicle is folded, the movable vehicle arm and the fixed vehicle arm are unlocked, the movable vehicle arm rotates around the rotating shaft and gets close to the unmanned aerial vehicle body, and the unmanned aerial vehicle arm is in a folded state. The stress of the folding locking mechanism is shared by a plurality of parts, the failure risk of the folding locking mechanism is greatly reduced, the reliability of the folding locking mechanism is improved, and the service life of the folding locking mechanism is prolonged.
本申请属于无人机结构设计技术领域,特别涉及一种无人机机臂折叠锁紧机构及无人机。无人机机臂折叠锁紧机构包括固定机臂和活动机臂,固定机臂固设于无人机主体,活动机臂通过折叠锁紧机构与固定机臂相连接。折叠锁紧机构包括:固定基座、活动基座、转轴和卡扣。当活动机臂与固定机臂对接并锁紧,无人机机臂处于展开状态;活动机臂与固定机臂之间解锁,活动机臂绕转轴转动,向无人机主体靠拢,无人机机臂处于折叠状态。本申请的折叠锁紧机构的受力由多个部分分担,大大降低了折叠锁紧机构的失效风险,提高了折叠锁紧机构的可靠性和使用寿命。
