具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
还应当理解，在本申请说明书中所使用的术语仅仅是出于描述特定实施例的目的而并不意在限制本申请。如在本申请说明书和所附权利要求书中所使用 的那样，除非上下文清楚地指明其它情况，否则单数形式的“一”、“一个”及“该”意在包括复数形式。
还应当进一步理解，在本申请说明书和所附权利要求书中使用的术语“和/或”是指相关联列出的项中的一个或多个的任何组合以及所有可能组合，并且包括这些组合。
本申请的发明人发现，一般情况，飞行器包括机体及多个与机体固定连接的机臂，机臂上安装有由电机驱动高速旋转的螺旋桨，从而使得飞行器能够借助螺旋桨高速旋转产生气流的反作用力驱动飞行器飞行。
然而飞行器在飞行过程中难免会触碰各种建筑、树枝或其他物品等，为了解决这个问题，通常情况会在螺旋桨的外侧加上保护罩以将螺旋桨整体罩住，从而可以对螺旋桨进行保护。
现有的螺旋桨的保护装置，其仅为利用自身强度来保护人或其他物体，对螺旋桨的保护范围有限，在飞行器触碰的过程中，高速旋转的螺旋桨可能由于没有被保护罩保护住而对人或其他物体造成割伤，致使飞行器在使用过程中存在安全隐患。
为此，本申请的发明人对保护机构、无人机组件及无人机进行了改进，以降低螺旋桨的转速，提高无人机的使用安全性和可靠性。具体地，本申请实施例提供一种保护机构，用于保护无人机，所述保护机构包括：连接体，与所述无人机连接；保护罩，与所述连接体连接；其中，至少部分所述连接体和/或至少部分所述保护罩在外力作用下能够发生弹性形变以使得至少部分所述连接体和/或所述保护罩能够接触所述无人机的动力装置的转动部位，进而降低所述动力装置的转速。
本申请实施例还提供一种保护机构，用于保护无人机，所述保护机构用于安装于所述设于所述无人机的动力装置的转动部位的外部，当所述保护机构在外力的作用下发生弹性形变时，至少部分所述保护机构与所述转动部位接触，从而降低所述转动部位的转速。
本申请实施例还提供一种无人机组件，包括：机臂；电机，设于所述机臂上；螺旋桨，与所述电机连接；上述任一实施例的保护机构，所述连接体连接于所述机臂和/或所述电机。
本申请实施例还提供一种无人机，包括：机身；以及上述任一实施例的无人机组件，所述机臂与所述机身连接。
