【技术实现步骤摘要】
一种无人机的可更换机臂插拔结构
本专利技术涉及无人机
,尤其是涉及到多旋翼无人机的可更换机臂插拔结构。
技术介绍
近年来,多旋翼无人机的使用日益广泛。多旋翼无人机的主要结构由位于中央的机身和伸出周围的机臂组成,螺旋桨和马达安装于机臂末端组成动力系统。这种结构带来了飞行上的灵活性和垂直起降能力,但这种结构使得多旋翼无人机的展开直径较大,不利于运输和存放。同时,一种无人机只搭载一种动力系统也无法满足多样化的飞行环境的需要。为了提高多旋翼无人机便携能力,必须缩小无人机体积,使机身和机臂之间的连接变为可活动的,还要保证结构的强度和重量要求。现有的一些折叠结构可以一定程度上缩小多旋翼无人机的存放体积,但由于机臂和机身之间仍然连接,无法最大程度的提高存放空间的利用率,必须采取机臂和机身分离的结构才能进一步提升多旋翼无人机的便携性,根据实际任务的需求快速安装和更换不同的动力系统。
技术实现思路
本专利技术的目的是提供一种无人机的机臂和机身之间的快速插拔连接机构,同时兼顾强度和轻量化。通过简单快速的定位连接和拆卸,完成特定型号机臂的拆装,满足存放体积和不同飞行任务的需要。为了实 ...
