飞行时,所述机臂11处于展开状态,所述主机臂111与所述无人机100的航向方向垂直。两个副机臂112位于所述机身20的一侧,另外两个副机臂112位于所述机身20的另一侧。位于同一侧的两个副机臂112位于同一直线上,并且与所述主机臂111垂直。可以理解的是,在其它一些实施例中,位于同一侧的两个副机臂112还可以根据实际需求设置,如,位于同一侧的两个副机臂112形成第一夹角,该第一夹角可以是钝角或锐角;所述副机臂112与所述主机臂111形成第二夹角,该第二夹角可以使钝角或锐角(即在所述机臂11展开时,位于同一侧的两个副机臂112可向外稍稍张开,并且与所述主机臂111呈钝角或锐角)。
在飞行结束后,由于所述副机臂112可相对于所述主机臂111旋转以进行折叠。因此,先转动所述副机臂112,使得四个副机臂112均与所述主机臂111平行,此时所述动力组件10经折叠后,其结构变得非常紧凑,形成一个矩形框架。然后将所述主机臂111连同四个副机臂112一起相对于机身20旋转九
十度,使得整个无人机100经折叠后,其结构变得非常紧凑,便于携带,同时也可以有效的防止所述无人机100在携带时,因碰撞而发生损坏。
所述动力组件10经折叠后,其形状和大小与所述机身20相对应。在本实施例中,所述动力组件10经折叠后,其形状为矩形,所述机身20的形状也为矩形。
可以理解的是,所述机身20的形状可以根据实际需求设计为圆形或椭圆形等;对应的,所述动力组件10经折叠后,其形状为圆形或椭圆形。
在其它一些实施例中,所述副机臂112、驱动装置12和螺旋桨的个数不限于四个,其可以根据实际需求而设计,如两个、三个或者四个以上。

所述动力组件10a包括两个机臂11a、四个驱动装置12a和四个螺旋桨。所述机臂11a包括一个主机臂111a和两个副机臂112a和一个连接件113a。两个所述主机臂111a的一端分别安装于所述机身20的两相对侧,并且所述主机臂111a可相对于所述机身20转动。所述主机臂111a的另一端与所述连接件113a的侧面铰接。两个副机臂112a的一端分别与所述连接件113a的两端铰接。每个副机臂112a的另一端与一个驱动装置12a固定连接,并且所述副机臂112a可相对于所述主机臂111a旋转以实现折叠。所述主机臂111a与所述机身20的连接处设置有限位结构以及弹性部件,并且所述弹性部件可以提升操作的便利性以及手感。所述主机臂111a和副机臂112a的连接处设置有限位结构以及弹性部件,在其它一些实施例中,也可用弹簧锁之类的结构锁死。
可以理解的是,在其它一些实施例中,所述主机臂111a和所述机身20a连接处设置有弹簧锁。
可以理解的是,所述连接件113a可以省略,而直接将所述副机臂112a的一端与所述主机臂111a铰接,并且另一副机臂112a的一端与所述副机臂112a的一端铰接。
四个螺旋桨分别安装于四个驱动装置12a。所述四个副机臂112a的长度相等,并且两个副机臂112a的长度与所述主机臂111a的长度大体相等。所述
主机臂111a和副机臂112a的截面形状为矩形。
可以理解的是,所述主机臂111a和副机臂112a的截面形状并不限于矩形,其可以根据实际需求设置,如圆形、三角形或者其它不规则形状等。
飞行时,所述机臂11a处于展开状态,所述主机臂111a与所述无人机200的航向方向垂直。两个副机臂112a位于所述机身20的一侧,另外两个副机臂112a位于所述机身20的另一侧。位于同一侧的两个副机臂112a位于同一直线上,并且与所述主机臂111a垂直。可以理解的是,在其它一些实施例中,位于同一侧的两个副机臂112a还可以根据实际需求设置,如,位于同一侧的两个副机臂112a形成第一夹角,该第一夹角可以是钝角或锐角;所述副机臂112a与所述主机臂111a形成第二夹角,该第二夹角可以使钝角或锐角。
在飞行结束后,先转动位于同一侧的两个副机臂112a中的一个,另一个副机臂112a不动,使得位于同一侧的两个副机臂112a相互重叠;然后,将主机臂111a相对于所述机身20转动九十度;最后转动所述连接件113a,使得位于同一侧的两个副机臂112a与所述主机臂111a重叠。基于以上结构设计,使得整个无人机200经折叠后,其结构变得非常紧凑,便于携带,同时也可以有效的防止所述无人机200在携带时,因碰撞而发生损坏。
可以理解的是,在其它一些实施例中,位于同一侧的两个副机臂112a(即同一个机臂上的两个副机臂),其中一个副机臂112a的一端与所述连接件113a铰接,另一个副机臂112a的一端与所述连接件113a固定连接。在所述无人机200飞行时,位于同一侧的两个副机臂112a位于同一直线上,并且与所述主机臂111a垂直;在飞行结束后,将与所述主机臂111a铰接的副机臂112a旋转一百八十度,使得位于同一侧的两个副机臂112a相互重叠;然后,将主机臂111a相对于所述机身20转动九十度;最后转动所述连接件113a,使得位于同一侧的两个副机臂112a与所述主机臂111a重叠在一起。基于以上结构设计,使得整个无人机200经折叠后,其结构变得非常紧凑,便于携带,同时也可以有效的防止所述无人机200在携带时,因碰撞而发生损坏。
上述各实施中,铰接(即铰链连接)只是一种连接方式的举例。可以理解,在其他实施例中,还可以用其他非刚接的连接方式代替铰接的方式,只要能使副机臂(112,112a)可相对于主机臂(111,111a)旋转以实现折叠即可,这里不作严格限制。
