具体地,请参阅图1,是本发明第一实施例的一种可折叠的无人飞行器100的立体示意图。在本实施方式中,所述无人飞行器100为旋翼无人飞行器,其用于搭载照相机、摄像机等拍摄装置(图未示)进行航拍作业。可以理解,所述无人飞行器100还可以用于执行地图测绘、灾情调查和救援、空中监控、输电线路巡检等工作。同样可以理解的是,在其他实施方式中,所述无人飞行器100还可以为固定翼无人飞行器。
在本实施方式中,所述无人飞行器100至少包括机身20以及用于提供飞行动力的飞行组件30。所述机身20的形状可以为各种形状,例如长方体、球体、椭圆体等。
如图1所示,用原点O来标示所述无人飞行器100的重心,可根据所述原点O来分别定义出所述无人飞行器100的横滚轴X(沿X轴方向)、俯仰轴Y(沿Y方向)、偏航轴Z(沿Z轴方向)。所述无人飞行器100在飞行过程中可被配置为相较于所述横滚轴X、俯仰轴Y、偏航轴Z中的一个或多个轴旋转。
在本实施方式中,所述机身20可包括头部20-1、尾部20-2、侧表面20-3和20-4、顶部20-5、底部20-6(如图5所示)。其中,所述头部20-1可位于所述机身20沿所述横滚轴X方向的一端、所述尾部20-2可位于所述机身20沿所述横滚轴X方向的另一端。所述侧表面20-3和20-4可位于所述机身20沿所述俯仰轴Y方向的两端。所述顶部20-5可位于所述机身20沿所述偏航轴Z方向的一端、所述底部20-6可位于所述机身20沿所述偏航轴Z方向的另一端。
进一步地,所述顶部20-5是指所述无人飞行器100处于正常飞行状态时面向天空的一个表面,所述底部20-6是指所述无人飞行器100正常着陆时面向地面的一个表面,所述侧表面20-3、20-4是指连接所述顶部20-5与所述底部20-6的表面。
请一并参阅图1-5,在本实施方式中,所述飞行组件30可活动地连接于所述机身20,使所述飞行组件30能够相对于所述机身20选择性地处于折叠状态或者展开状态。具体地,当所述无人飞行器100处于闲置的非飞行状态时,所述飞行组件30能够相对于所述机身20转动,并收拢于所述机身20的周围呈所述折叠状态,使所述飞行组件30所占用的空间较小,从而使所述无人飞行器100在闲置的非飞行状态时的结构比较紧凑,便于收纳及携带。当所述无人飞行器100处于飞行状态时,所述飞行组件30能够相对于所述机身20展开,以便给所述无人飞行器100提供飞行动力。
其中,在所述折叠状态与所述展开状态时,所述飞行组件30相较于所述机身20的侧表面20-3或20-4的距离不相同。在本实施方式中,所述飞行组件在所述折叠状态时相较于所述机身的侧表面的距离,小于在所述展开状态时相较于所述机身的侧表面的距离。
在本实施方式中,所述飞行组件30包括机臂31,所述机臂31可转动地连接于所述机身20的侧表面20-3、20-4,使所述机臂31能够相对于所述机身20选择性地处于折叠状态或者展开状态。其中,所述机臂31的数量可以为多个,例如,三个、四个、五个、六个或六个以上。在本实施方式中,所述机臂31的数量为四个。
在本实施方式中,在所述折叠状态与所述展开状态时,所述机臂31的自由端相较于所述机身20的侧表面20-3或20-4的距离不相同。
具体地,在本实施方式中,所述机臂31能够相对于所述机身20选择性地保持于预定的折叠位置(如图4-5所示的位置)以及预定的展开位置(如图1-2所示的位置),且能够在所述折叠位置与所述展开位置之间转动。其中,当所述机臂31位于所述折叠位置时,所述机臂31的自由端紧贴所述机身20,当所述机臂31位于所述展开位置时,所述机臂31的自由端远离所述机身20。也就是说,所述机臂31的自由端在所述折叠状态时相较于所述机身20的侧表面20-3或20-4的距离,小于在所述展开状态时相较于所述机身20的侧表面20-3或20-4的距离。
可选地,所述机身20上还可包括转动限位结构(图未示),所述转动限位结构用于与所述机臂31连接,并限定所述机臂31的转动角度。其中,所述转动限位结构可为挡块或弹性件,例如可提供预紧力及/或回弹力的弹片、弹簧等。
可选地,所述机身20上还可包括锁定结构(图未示),所述锁定结构用于与所述机臂31连接,并在所述展开状态下使所述机臂31能够保持于所述预定的展开位置,以及在所述折叠状态下使所述机臂31能够保持于所述预定的折叠位置。其中,所述锁定结构可为卡扣、卡钩等。
可选地,所述机身20上还可包括弹性件(图未示),所述弹性件用于与所述机臂31连接,并在所述机臂31相对于所述机身20折叠到第一预定位置时驱使所述机臂31自动缩回到所述预定的折叠位置,及/或,在所述机臂31相对于所述机身20展开到第二预定位置时驱使所述机臂31自动展开到所述预定的展开位置。
请再次参阅图1,在本实施方式中,所述飞行组件30还包括连接于所述机臂31的自由端的脚架32,所述脚架32用于在所述无人飞行器100的着陆过程中保护所述机身20不受到撞击以及在所述无人飞行器100着陆于一支撑面(图未示),例如地面时支撑所述机身20。
在本实施方式中,所述飞行组件30还包括连接于所述机臂31的自由端的、用于提供飞行动力的动力装置33。其中,所述动力装置33可以包括推进单元331以及致动器332。其中,所述推进单元331通过所述致动器332连接至相应机臂31的自由端。所述推进单元331可以使得所述无人飞行器100移动,并可以提供所述无人飞行器100的上升动力,以使所述无人飞行器100改变高度。其中,所述推进单元331可以是用于旋转以提供上升动力给所述无人飞行器100的旋翼。在本实施方式中,所述推进单元331采用螺旋桨,且包括至少两片桨叶,所述螺旋桨的桨叶能够折叠在一起,从而可缩短所述桨叶的收容空间,从而有利于在折叠状态下减小所述无人飞行器100的机身20在长度方向上的体积。
所述致动器332可以是电机,例如,交流电机或直流电机。所述致动器332用于响应来自所述无人飞行器100的飞行控制器的指令信号,以带动所述推进单元331转动,从而提供所述无人飞行器100的升力。其中,所述指令信号包括对所述致动器332的输出。
在本实施方式中,由于所述脚架32以及所述动力装置33均连接于所述机臂31的自由端,因此,在所述折叠状态与所述展开状态时,所述脚架32以及所述动力装置33相较于所述机身20的侧表面20-3或20-4的距离也均不相同。
具体地,在本实施方式中,所述脚架32以及所述动力装置33在所述折叠状态时相较于所述机身20的侧表面20-3或20-4的距离,均小于在所述展开状态时相较于所述机身20的侧表面20-3或20-4的距离。
在本实施方式中,连接于同一所述机臂31的所述脚架32与所述动力装置33分别位于所述机臂31的自由端的相对两侧,且所述脚架32在所述机臂31位于所述展开位置时凸出于所述机身20的底部20-6。
请一并参阅图6-7,在本实施方式中,在所述折叠状态与所述展开状态时,所述飞行组件30相较于所述机身20的底部20-6的高度也不相同。
具体地,在所述折叠状态与所述展开状态时,所述脚架32以及所述动力装置33相较于所述机身20的底部20-6的高度均不相同。
在本实施方式中,所述机臂31包括第一机臂31-1,其中,在所述折叠状态与所述展开状态时,所述第一机臂31-1的自由端相较于所述机身20的底部20-6的高度不相同。
具体地,所述第一机臂31-1可相对于所述机身20的侧表面20-3或20-4绕第一转动轴311-1转动。其中,所述第一转动轴311-1相对于所述无人飞行器100的偏航轴Z呈第一预定倾斜角度α,且所述第一转动轴311-1大致平行于所述无人飞行器100的偏航轴Z与横滚轴X所确定的平面。
在本实施方式中,由于所述第一转动轴311-1的倾斜设置,且所述第一机臂31-1绕所述第一转动轴311-1在同一平面上转动,使得所述第一机臂31-1自所述折叠状态转动以进入所述展开状态的同时,所述第一机臂31-1的自由端相较于所述机身20的底部20-6的高度降低。即,所述第一机臂31-1的自由端在所述折叠状态时相较于所述机身20的底部20-6的高度,大于在所述展开状态时相较于所述机身20的底部20-6的高度。
在本实施方式中,所述第一预定倾斜角度α为2-3度。可以理解的是,所述第一预定倾斜角度α可以根据实际情况调整,从而调整所述第一机臂31-1的自由端相对于所述机身20的底部20-6的高度幅度。
在本实施方式中,连接于所述第一机臂31-1的所述脚架32以及所述动力装置33的朝向在所述第一机臂31-1的转动过程中均保持不变。在本实施方式中,连接于所述第一机臂31-1的所述脚架32始终朝向所述机身20的底部20-6,连接于所述第一机臂31-1的所述动力装置33始终朝向所述机身20的顶部20-5。
在本实施方式中,由于所述第一转动轴311-1的倾斜设置,使得连接于所述第一机臂31-1的所述脚架32的自由端在所述折叠状态时凸出于所述机身20的底部20-6的长度为H1,在所述展开状态时凸出于所述机身20的底部20-6的长度为H2,其中,H1<H2。因此,连接于所述第一机臂31-1的所述脚架32的自由端在所述折叠状态时相较于所述机身20的底部20-6的高度(-H1),大于在所述展开状态时相较于所述机身20的底部20-6的高度(-H2)。
在本实施方式中,所述脚架32在所述第一机臂31-1位于所述展开位置时凸出于所述机身20的底部20-6,即所述长度H2为正数。所述脚架32在所述第一机臂31-1位于所述折叠位置时也凸出于所述机身20的底部20-6,即所述长度H1也为正数。
可以理解的是,在其他实施方式中,可根据实际情况调整所述第一机臂的转动轴的第一预定倾斜角度,或调整所述脚架32的长度,使得所述脚架32在所述第一机臂31-1位于所述折叠位置时不凸出于所述机身20的底部20-6,即所述长度H1为零或为负数。
本实施例的所述无人飞行器100通过倾斜设置所述第一机臂31-1的第一转动轴311-1,并通过所述第一机臂31-1带动所连接的所述脚架32转动以调整所连接的所述脚架32的高度,使连接于所述第一机臂31-1的脚架32在所述折叠状态与所述展开状态下产生高度差,从而可改变所述脚架32凸出于所述机身20的底部20-6的长度。
由于在所述折叠状态时所述第一机臂31-1上的所述脚架32凸出于所述机身20的底部20-6的长度减小或消失,从而有利于在所述折叠状态下减小所述无人飞行器100的机身20在高度方向上的体积,使折叠后的所述无人飞行器100的结构更加紧凑。而且不需要在所述第一机臂31-1的自由端增加转动机构以折叠相应的脚架32,结构较简单。
在本实施方式中,连接于所述第一机臂31-1的所述动力装置33在所述折叠状态时相较于所述机身20的底部20-6的高度,大于在所述展开状态时相较于所述机身20的底部20-6的高度。如图6所示,在本实施方式中,所述第一机臂31-1在所述折叠状态时将所连接的所述动力装置33的推进单元331搁置于所述机身20的顶部20-5。
在本实施方式中,所述机臂31还包括第二机臂31-2,如图2所示,所述第二机臂31-2可相对于所述机身20的侧表面20-3或20-4绕第二转动轴311-2转动。其中,所述第二转动轴311-2相对于所述无人飞行器100的横滚轴X呈第二预定倾斜角度β,且所述第二转动轴311-2大致垂直于所述无人飞行器100的偏航轴Z,使得所述第二机臂31-2绕所述第二转动轴311-2沿一圆锥面旋转。
在本实施方式中,由于所述第二机臂31-2沿圆锥面旋转,使得所述第二机臂31-2自所述折叠状态转动以进入所述展开状态的同时,所述第二机臂31-2相较于所述机身20翻转180度,使所述第二机臂31-2朝向所述机身20的顶部20-5的表面转为朝向所述机身20的底部20-6。
在本实施方式中,连接于所述第二机臂31-2的所述脚架32的朝向在所述第二机臂31-2的转动过程中也跟随所述第二机臂31-2翻转180度,即连接于所述第二机臂31-2的所述脚架32在所述折叠状态时朝向所述机身20的顶部20-5,在所述展开状态时朝向所述机身20的底部20-6。因此,连接于所述第二机臂31-2的所述脚架32的自由端在所述折叠状态时相较于所述机身20的底部20-6的高度,大于在所述展开状态时相较于所述机身20的底部20-6的高度。
本实施例的所述无人飞行器100通过所述第二机臂31-2沿圆锥面旋转,并通过所述第二机臂31-2带动所连接的所述脚架32翻转以调整所连接的所述脚架32的高度,使连接于所述第二机臂31-2的脚架32在所述展开状态时凸出于所述机身20的底部20-6,在所述折叠状态时朝向所述机身20的顶部20-5,且不凸出于所述机身20的顶部20-5。
由于在所述折叠状态时所述第二机臂31-2上的所述脚架32朝向所述机身20的顶部20-5,且不凸出于所述机身20的顶部20-5,从而有利于在所述折叠状态下减小所述无人飞行器100的机身20在高度方向上的体积,使折叠后的所述无人飞行器100的结构更加紧凑。而且不需要在所述第二机臂31-2的自由端增加转动机构以折叠相应的脚架32,结构较简单。
在本实施方式中,连接于所述第二机臂31-2的所述动力装置33的朝向在所述第二机臂31-2的转动过程中也跟随所述第二机臂31-2翻转180度,即连接于所述第二机臂31-2的所述动力装置33在所述折叠状态时朝向所述机身20的顶部20-5,在所述展开状态时朝向所述机身20的底部20-6。因此,在本实施方式中,连接于所述第二机臂31-2的所述动力装置33在所述折叠状态时相较于所述机身20的底部20-6的高度,小于在所述展开状态时相较于所述机身20的底部20-6的高度。如图6所示,在本实施方式中,所述第二机臂31-2在所述折叠状态时将所连接的所述动力装置33的推进单元331搁置于所述机身20的底部20-6。
在本发明实施例中,所述机臂31在所述折叠状态时将相应的推进单元331搁置于所述机身23的顶部20-5或底部20-6。在其他实施方式中,所述机臂31的自由端附近可设有转动机构(图未示),所述转动机构用于在所述折叠位置时转动所述机臂31的自由端,使所述推进单元331搁置于所述机身20的侧表面20-3或20-4。
在本发明实施例中,所述无人飞行器100通过所述机臂31相对所述机身20旋转,以实现在所述折叠状态时缩短所连接的所述脚架32凸出于所述机身20的长度。在其他实施方式中,所述脚架32能够相对于所连接的机臂31折叠至贴附于所连接的机臂31上,以便在所述折叠状态下减小所述无人飞行器100的体积,使所述无人飞行器100的结构更加紧凑。
在本发明实施例中,所述无人飞行器100包括至少一对所述第一机臂31-1以及至少一对所述第二机臂31-2。在本实施方式中,每一对所述第一机臂31-1相对连接于所述机身20的两个侧表面20-5和20-6,每一对所述第二机臂31-2相对连接于所述机身20的两个侧表面20-5和20-6。所述第一机臂31-1以及所述第二机臂31-2分别连接于所述机身20的同一侧表面的相对两端,且所述第一机臂31-1与所述第二机臂31-2上下错位,使所述第一机臂31-1与所述第二机臂31-2在所述折叠状态时能够相互扣合在一起。
可选的,在其他实施方式中,所述无人飞行器100可包括多个所述第一机臂31-1,例如,所述第一机臂31-1的数量可为四个、六个、八个或其他数量。例如图8所示,所述无人飞行器200的多个所述第一机臂31-1分别连接于所述机身21的不同的侧表面21-1。所述第一机臂31-1在所述折叠状态时将所连接的所述动力装置33的推进单元331搁置于所述机身21的顶部21-2。
或者,例如图9所示,所述无人飞行器300的多个所述第一机臂31-1分别两两相对连接于所述机身22的同一侧表面22-1的相对两端,且两两相对连接于所述机身22的相对两侧表面22-1上。所述第一机臂31-1在所述折叠状态时将所连接的所述动力装置33的推进单元331搁置于所述机身22的顶部22-2。进一步地,所述机身22的长度至少不小于两个所述第一机臂31-1的长度之和,从而可将两个所述第一机臂31-1所连接的推进单元331并排搁置于所述机身22的顶部22-2。
可以理解的是,在其他实施方式中,所述无人飞行器100也可包括多个所述第二机臂31-2,例如,多个所述第二机臂31-2可分别连接于所述机身20的不同的侧表面,或者,两两相对连接于所述机身20的同一侧表面的相对两端,或者,两两相对连接于所述机身20的相对两侧表面上。
可选的,在其他实施方式中,例如图10-11所示,所述无人飞行器400还包括设置于所述机身23上的转动机构61,所述转动机构61将所述机身23分为两部分,且使所述机身23的其中一部分能够相对于另一部分绕所述转动机构61的第三转动轴611旋转180度。其中,所述第三转动轴611大致平行于所述无人飞行器400的横滚轴X。
如图12所示,当所述机身23的其中一部分相对于另一部分绕所述转动机构61的第三转动轴611旋转180度后,使得连接于所述机身23的其中一部分的飞行组件30相对连接于所述机身23的另一部分的飞行组件30旋转180度。即,连接于同一侧表面20-3或20-4的两个所述机臂31上的飞行组件30的朝向相反。其中,连接于所述机身23的两部分的所述机臂31,例如第一机臂31-1在所述折叠状态时分别将相应的推进单元331搁置于所述机身23的顶部23-2和底部23-1。可以理解的是,所述机臂31也可以是所述第二机臂31-2。
其中,所述机身23的长度可大致等于一个所述机臂31的长度,以缩短机身23的长度,从而有利于在折叠状态下减小所述无人飞行器400的机身23在长度方向上的体积。
请再次参阅图1,在本发明实施例中,所述机身20上还设有第一安装部24,所述第一机臂31-1安装于所述第一安装部24上。其中,所述第一安装部24凸设于所述机身20上。在其他实施方式中,所述机身20上还可设有导向槽(图未示),所述第一机臂31-1安装于所述导向槽中,所述第一机臂31-1位于所述折叠位置时收容于所述导向槽中。

在其他实施方式中,如图13-14所示,收容部261可设于所述机身20的顶部20-5与侧表面20-3或20-4的交界处,及/或,设于所述机身20的底部20-6与侧表面20-3或20-4的交界处。其中,所述收容部261与相应的致动器332的部分结构的形状相适配。
可选的,所述无人飞行器100还可包括通信天线(图未示),所述脚架32还用于给所述通信天线提供附设空间。在本实施方式中,所述脚架32相对于所连接的机臂31的长度方向呈非正交角度,从而在不增加所述脚架32凸出于所述机身20的长度的情况下增大所述通信天线与所述机身20之间的距离,使得所述通信天线能够尽可能远离所述机身20内的电子元件产生的电磁干扰,以利于改善所述天线传输信号的性能。
所述机身20可以为一壳体,其内部可包含有所述无人飞行器100的其他元件,例如飞行控制器、惯性测量单元(Inertial measurement unit,IMU)、电调、电池等。

如图15所示,在本实施方式中,也可以理解为所述无人飞行器100包括机架71、动力系统72、飞行控制系统73。其中,所述动力系统以及所述飞行控制系统设置于所述机架71上或设置于所述机架71内。所述机架71至少包括所述机身20(或21或22或23)、所述机臂31以及所述脚架32。所述机身20(或21或22或23)也可称为中心架。在本实施方式中,所述机臂31与所述机身20(或21或22或23)连接,所述脚架32与所述机臂31的自由端连接。在其他实施方式中,所述机臂31和所述脚架32分别与所述机身411连接。
