请再参阅图1,所述支臂212用于支撑对应的所述主臂211。所述支臂212的两端分别能够转动地连接于所述主臂211以及所述机身10上。具体地,所述支臂212的一端能够转动地连接于主臂211的枢接部2113a上,另一端能够转动地连接于所述机身10的对应的所述第一机臂安装部15上。本实施方式中,所述支臂212大致为细长杆状。优选地,所述支臂212的长度与所述枢接部2113a至所述连接部2111之间的距离之和小于所述第一滑槽132(或者第二滑槽142)。

本实施方式中,所述第一机臂21将对应的动力组件30支撑于所述机身10的第一高度处,所述第二机臂22将对应的动力组件30支撑于所述机身10的第二高度处,所述第一高度与所述第二高度不同。
可以理解,所述第二机臂22的转轴可以与所述无人飞行器100的偏航轴呈预定夹角,及/或与所述无人飞行器100的横滚轴(roll轴)呈预定夹角,使得所述第二机臂22转动的同时,对应的所述动力组件30相对于所述机身10的角度及/或高度改变。
可以理解,所述第二机臂22上也可以设置类似所述第一机臂21的扭转部2113b的结构,使得所述第二机臂22上连接的所述动力组件30能够相对于所述第二机臂22扭转预定角度。
所述动力组件30能够为所述无人飞行器100提供飞行的动力。每一个所述动力组件30包括电机31以及与所述电机31相连的螺旋桨32。所述电机31用于驱动所述螺旋桨32旋转以产生驱动力。所述电机31固定连接于对应的所述机臂20的安装部2112上,连接的方式可以为卡合、螺纹连接、焊接或者粘结中一种或者几种。所述电机31可以为无刷电机或者有刷电机,本实施方式中,所述电机31为无刷电机。所述螺旋桨32通过旋转产生驱动力以使所述无人飞行器100进行上升、下降、加速、减速、翻滚、悬停等动作。本实施方式中,所述螺旋桨32为可折叠桨,即所述无人飞行器100不飞行时,所述螺旋桨32的桨叶可以相互叠合,以减小所述无人飞行器100的体积。
本实施方式中,所述螺旋桨32包括两个桨叶,可以理解,依据不同的需求,所述螺旋桨32包括的桨叶的数量可以变化,例如桨叶的数量可以为三个、四个等。
当所述无人飞行器100处于飞行状态时,所述第一机臂21以及所述第二机臂22相对于所述机身10处于展开状态,即所述第一机臂21以及所述第二机臂22安装所述动力组件30的端部向所述机身10外延伸,并且将对应的所述动力组件30支撑于所述机身10周围的预定位置处。此时,所述第一机臂21的安装部2112分别连接于对应的所述第一机臂安装部15上,所述支臂212能够辅助支撑对应的所述主臂211,防止所述主臂211的摆动。
请参阅图7至图9,当所述无人飞行器100不需飞行时,可以讲所述动力组件30的螺旋桨32的桨叶相对折叠,所述第一机臂21以及所述第二机臂22能够相对于所述机身10折叠且能够抵靠在所述机身10的侧部。具体地,所述第一机臂21向远离对应的所述第一机臂安装部15的方向沿所述第一滑槽132(或者所述第二滑槽142)滑动,滑动过程中,对应的所述支臂212亦相对于对应的所述主臂211转动,当所述第一机臂21滑动至大致与所述第一滑槽132(或者所述第二滑槽142)平行时,对应的所述安装部2112与靠近对应的第一机臂安装部15,使得对应的所述动力组件30靠近所述第一机臂安装部15设置,本实施方式中,折叠后所述第一机臂21连接于所述第二机臂安装部16。在所述第一机臂21相对于所述机身10折叠前、折叠后或者折叠过程中,可以通过对应的所述扭转部2113b改变对应的所述动力组件30的朝向,本实施方式,所述动力组件30通过所述扭转部2113b旋转90度,旋转后,所述动力组件30的朝向与所述第一侧面131的朝向大致相同。所述第二机臂22够相对于所述机身10向所述第一机臂21侧转动,折叠后的所述第二机臂22大致与所述第一机臂21垂直,所述第二机臂22对应的所述动力组件30靠近所述第一机臂安装部15,所述第二机臂22对应的所述动力组件30的朝向与所述第一机臂21对应的所述动力组件30的朝向不同,如此,可以避免折叠后不同机臂上的动力组件30相互干涉,而且可以进一步减小折叠后的所述无人飞行器100的体积,便于无人飞行器100的携带及运输。
请参阅图10,在另一实施方式中,所述动力组件30可以旋转180度,旋转后,所述动力组件30的朝向与旋转前的方向相反,同样,此种折叠方式,可以避免折叠后不同机臂上的动力组件30相互干涉,而且可以进一步减小折叠后的所述无人飞行器100的体积,便于无人飞行器100的携带及运输。
请参阅图11,所示为本发明第二实施方式的一种无人飞行器200的示意图。本实施方式中,所述无人飞行器200的第一机臂21’以及第二机臂22’具有大致相同的结构,所述第一机臂21’能够转动地连接于第一机臂安装部15’,所述第二机臂22’能够转动地连接于第二机臂安装部16’上,所述第一机臂21’以及所述第二机臂22’中的每一个包括第一臂部41以及一个第二臂部42,所述第一臂部41与对应所述第一机臂安装部15’(或者所述第二机臂安装部16’)可转动地连接,所述第一臂部41与所述第二臂部42之间能够转动地连接,所述第一臂部41与所述第二臂部42之间的相对转动的转轴大致平行于所述第一臂部41相对于所述第一机臂安装部15’(或者所述第二机臂安装部16’)转动的转轴。
可以理解,所述第一臂部41与所述第二臂部42之间相互转动的结构可以参考第一实施方式中所述枢接部2113a或者所述扭转部2113b,不再一一赘述。
请参阅图12及图13,当所述无人飞行器100不需飞行时,所述第一机臂21’以及所述第二机臂22’均可相对于所述机身10’折叠。具体地,所述第一臂部41转动至大致与所述机身10’的侧部平行的位置,对应的所述第二臂部42相对于所述第一臂部41反向折叠,使得对应的动力组件30’靠近对应的机臂安装部(第一机臂安装部15’或者第二机臂安装部16’)设置。折叠后,所述第一机臂21’对应的所述动力组件30’与所述第二机臂22’对应的所述动力组件30’沿所述机身10’的朝向相同,且所述第一机臂21’对应的所述动力组件30’与所述第二机臂22’对应的所述动力组件30’于所述机身10’呈直线排列。此种折叠方式,可以避免折叠后不同机臂上的动力组件30’相互干涉,而且可以进一步减小折叠后的所述无人飞行器200的体积,便于无人飞行器200的携带及运输。
可以理解,所述第一机臂21’或者所述第二机臂22’中的一组可以与第一实施方式的第二机臂21相同。
可以理解,所述第一机臂21’及所述第二机臂22’中的至少一组可以设置第一实施方式的所述扭转部,使得所述第一机臂21’或者所述第二机臂22’对应的所述动力组件30的朝向可以调整,不再详述。
所述无人飞行器通过机臂相对于所述机身折叠达到减小体积的目的,方便无人飞行器在不使用时的携带及运输。
可以理解的是,本领域技术人员还可在本发明精神内做其它变化等用在本发明的设计,只要其不偏离本发明的技术效果均可。这些依据本发明精神所做的变化,都应包含在本发明所要求保护的范围之内。
