当螺旋桨10与驱动装置30旋转卡接时，所述驱动装置30的驱动轴32穿过所述弹性抵持件13，最终所述弹性抵持件13套设在所述驱动轴32上，并抵持于所述螺旋桨10和所述驱动装置30之间。可以理解的是，在其他实施例中，弹性抵持件13也可以设置在驱动装置30上，例如，可以套设在驱动装置30的驱动轴32上，只要弹性抵持件13能够在螺旋桨10与驱动装置30旋转卡接时，为螺旋桨10提供防止螺旋桨10从驱动装置30上松脱的抵持力即可。
具体地，在本实施例中，所述第一桨夹片11由金属材料制成。
所述第一桨夹片11的两端分别设置有连接孔111，所述第一桨夹片11 的中部与所述弹性抵持件13的一端固定连接。所述连接件14大体呈圆柱状，且共有两个。所述两个连接件14的一端分别与所述第二桨夹片12的一端固定连接，在不同的实现方式中，其固定连接的方式可以为：两个连接件14与所述第二桨夹片12一起注塑成型，为一体式结构或者两个连接件14通过铆接或者螺纹连接及加胶的方式固定连接。所述两个连接件14的另一端分别穿过所述连接孔111，并且所述两个连接件14的另一端可分别安装于所述第一桨夹片11的一端。例如，所述连接件14为一半空心铆钉，所述连接件14的另一端与所述第一桨夹片11铆接。
如图4所示，为图3中所示的螺旋桨中第二桨夹片12的结构示意立体图。在本实施例中，所述第二桨夹片12由非金属材料制成。
所述第二桨夹片12包括本体121和收容部122。所述本体121包括相对设置的第一表面1210和第二表面1212，所述第一表面1210面对所述第一桨夹片11。所述收容部122为中空圆柱体，所述收容部122的一端固定于所述本体121的所述第一表面1210。所述收容部122其内部形成有收容腔123，所述弹性抵持件13置于所述收容腔123内。
所述本体121的中部设置有第一通孔1211，所述收容腔123与所述第一通孔1211沿所述旋转轴线A的方向对齐，并且相互连通。
所述第二桨夹片12还包括从第二桨夹片12延伸行程的卡接部124，所述卡接部124的一端固定于所述本体121的第二表面1212；所述卡接部124的另一端具有挡块1241。具体的地，所述第二桨夹片12还包括用于限定所述桨叶旋转角度的限位结构，所述限位结构设置于所述本体121上。在本实施例中，所述卡接部124的个数为3个，所述挡块1241为由所述卡接部124的一端向垂直于所述卡接部124的方向延伸而成的凸块。所述卡接部124用于与所述安装座20卡扣连接，从而将螺旋桨10与为其提供动力的驱动装置30相互连接。
所述桨叶15共有两个。所述桨叶15的一端设置有枢接孔151，所述连接件14穿过所述枢接孔151，使得所述桨叶15枢接于所述第一桨夹片11和第二桨夹片12。
可以理解的是，在其它一些实施例中，所述连接件14和桨叶15的个数可以均为三个或三个以上。
可以理解的是，在其它一些实施例中，所述收容部122可为第一桨夹片11的一部分。

所述滑动件16也置于所述收容部122的收容腔123内，并且当所述弹性抵持件13压缩或伸展时，可在所述收容腔123内沿所述旋转轴线A做直线往复运动。
所述收容腔126的内壁上与两个凸起部162相对应的位置设有与两个凸起部形状相适配的凹槽1231。所述凸起部162嵌入所述凹槽1231内，用于防止所述滑动件16在所述收容腔123内发生相对所述第二桨夹片12的转动。所述弹性抵持件13的一端抵持第一桨夹片11，另一端抵持所述滑动件16。设置所述凸起部162和凹槽1231的目的是，通过所述凸起部162和凹槽1231的相互配合，限制弹性抵持件13只在上下方向上移动，而不会左右移动。若无上述结构，则弹性抵持件13会在所述收容腔123内发生左右晃动，从而影响螺旋桨10的动平衡。
图6和图7是分别从不同角度示出的图1的动力组件100中的安装座20的结构示意立体图。如图6-7所示，所述安装座20包括上端面210、下端面214及位于所述上端面210和所述下端面214之间的侧壁22。所述安装座20设置有第二通孔211，安装座20上还设置有行程槽212，在本实施例中，行程槽212设置在上表面210上。所述行程槽212呈圆弧形，并且该圆弧的圆心为所述第二通孔211的中心。所述行程槽212的数量与所述卡接部124的数量相等。所述卡接部124可穿过所述行程槽212与所述安装座20卡扣连接，并且所述卡接部124可沿所述行程槽212滑动。所述行程槽212的横截面形状为矩形，并且其一端的横截面积大于另一端的横截面积。所述卡接部124可从所述行程槽212的横截面积大的一端插入该行程槽212，并且所述卡接部124的挡块1241进入所述行程槽212内。
具体的，如图7所示，所述安装座20呈圆柱状，安装座20的下表面214向内凹陷形成凹槽216，所述凹槽216与所述行程槽212的另一端相对应，所述卡槽216与该行程槽212连通。每两个所述行程槽212之间设置有螺纹孔213，用螺栓或者螺丝穿过所述螺纹孔213可将所述安装座20安装于所述驱动装置30。
如图8所示，所述驱动装置30包括本体31和设置于本体31且能够相对于本体31转动的驱动轴32，所述本体31具有一承载面311，所述安装座20固定安装于所述承载面311上。所述螺旋桨10通过所述安装座20安装于所述承载面311上，进而安装至所述驱动装置30。所述安装座20的第二通孔211的中轴线与所述安装座20的中轴线重合，所述驱动轴32的一端穿设于所述第二通孔211中，并与所述第二桨夹片12连接。所述驱动轴32为一阶梯轴，其具有一台阶面321。所述弹性抵持件13和滑动件16均套设于所述驱动轴32，所述滑动件16可沿所述驱动轴32滑动。所述驱动轴32穿过所述第二通孔211，所述弹性抵持件13的一端抵持所述第一桨夹片11，另一端抵持所述滑动件16一表面。所述滑动件16的另一表面与所述驱动轴32的台阶面321抵接，即，所述弹性抵持件13的另一端通过所述滑动件16抵持所述驱动轴32的台阶面321。
在本申请另一实施例中，提供了一种无人飞行器，包括机身、机臂和上述动力组件100，所述机臂的一端与所述机身连接，所述动力组件100与所述机臂的另一端连接。
在对动力组件100进行组装时，先将所述安装座20固定安装于所述驱动装置30的承载面311上。然后将所述螺旋桨10中卡接部124的另一端对准所述行程槽212的一端，所述弹性抵持件13与所述驱动轴32对齐。接下来，按压所述螺旋桨10，使所述卡接部124的另一端进入所述行程槽212，并使得弹性抵持件13套设在所述驱动轴32上。此时，所述弹性抵持件13一端抵持第一桨夹片11，另一端抵持所述滑动件16，所述滑动件16抵接所述驱动轴32的台阶面321。所述弹性抵持件13受压力，被压缩。待所述卡接部124的挡块完全穿过所述行程槽212时，旋转所述螺旋桨10，使得所述卡接部124沿所述行程槽212，由所述行程槽212的一端滑动至另一端，直至所述卡接部124的挡块与所述卡槽对齐，此时，轻轻放松对所述螺旋桨10 的压力，使得弹性抵持件13可将所述螺旋桨10的其它部件沿所述驱动轴32向远离所述安装座20的方向移动，从而使得所述挡块嵌入所述卡槽。此时，所述挡块的左右侧面被所述卡槽卡住，上表面被所述安装座20的下表面214挡住，弹性抵持件13可防止所述挡块向下移动，即，所述挡块1241被完全固定住，从而使所述螺旋桨10固定安装于所述安装座20。
当需要对动力组件100进行拆卸时，先用手按压所述螺旋桨10，使所述卡接部124向下移动，直至所述挡块完全从所述卡槽中出来，然后旋转所述螺旋桨10，使所述卡接部124沿所述行程槽212，由所述行程槽212的另一端滑动至其一端，然后将所述卡接部124从所述行程槽212的一端内抽出，使得所述螺旋桨10与所述安装座20分离。然后松开螺栓，把所述安装座20从所述驱动装置30上卸下，从而完成拆卸过程。
本申请实施例的有益效果是：通过设置螺旋桨10的桨叶15可相对其第一桨夹片11和第二桨夹片12转动，使得该螺旋桨10的桨叶15可以相对其第一桨夹片11和第二桨夹片12旋转折叠，一方面，可以在收纳具有该螺旋桨10的无人飞行器时，提升其空间利用率，方便携带；另一方面，该螺旋桨10可拆卸地安装于驱动装置30上，可以在收纳具有该螺旋桨10的无人飞行器时，可以将该螺旋桨10拆卸下来单独收纳，以防损坏，并可在使用具有该螺旋桨10的无人飞行器时，能够快速地更换已损坏的螺旋桨。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；在本申请的思路下，以上实施例或者不同实施例中的技术特征之间也可以进行组合，步骤可以以任意顺序实现，并存在如上所述的本申请的不同方面的许多其它变化，为了简明，它们没有在细节中提供；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
