在一些实施例中,云台130可用于承载功能组件170。
在一些实施例中,第三耦合部137可通过第二转轴机构110a与机身110可转动连接。例如,第二转轴机构110a可与机身110的电机转子机械耦合,用以驱动第二转载机构110a转动,从而带动第一转轴机构130a转动;或者,第二转轴机构110a与机身110的电机的转子固定连接,从而使第二转轴机构110a随着转子的转动而转动;或者,第二转轴机构110a通过一传动机构通过一传动机构(例如:齿轮、蜗轮、蜗杆等)与所述电机的外转子连接,从而使所述外转子可以通过传动机构带动所述第二转轴机构110a转动。
在一些实施例中,第二转轴机构110a可沿飞行器100的俯仰轴方向或横滚轴方向延伸。
在一些实施例中,功能组件170还作为配重件使用,在转动的过程中,由功能组件170的重量产生的力矩与有传感器组件150的重量而产生的力矩基本相等,使得功能组件170及传感器组件150在转动的过程中可以保持机身110的稳定。例如:功能组件170可用于与传感器组件150一同转动,以稳定飞行器100的重心;或者,功能组件170的重心、传感器组件150的重心以及机身110的重心可基本处于同一直线;或者,功能组件170的重心到机身110的重心的距离与传感器组件150的重心到机身110的重心的距离基本相等;或者,功能组件170的重量与传感器组件150的重量基本相同。传感器组件150可以包括相机、雷达、超声波传感器、TOF传感器中的至少一个。
在一些实施例中,第一转轴机构130a的轴臂131可以是空心结构。第三耦合部137可以是环状结构。环状结构所在的平面与第二转轴机构110a基本垂直。环状结构的内壁设有螺纹,第二转轴机构110a机构与环状结构耦合处也设有螺纹,从而使得第二转轴机构110a与环状结构螺纹耦合;或者,环状结构设有卡合部,第二转轴机构110a设有配合部,通过卡合部与配合部相卡合,以将第二转轴机构110a与环状可拆卸连接起来。第二转轴机构110a设有环状结构可以是电滑环,轴臂131通过电滑环与机身110可转动连接。

在一些实施例中,传感器组件150与功能组件170之间不需要通信。例如:功能组件170可以包括电调组件。
图3为本发明飞行器云台俯视图,结合图1-图3,在一些实施例中,云台130还可包括第三转轴机构130b,用于使传感器组件135可以沿不同于第一转轴机构旋转的方向转动。例如:第三转轴机构130b的一端与第一转轴机构130a的第一耦合部133转动连接,传感器组件150与第三转轴机构130b的另一端固定连接,以使传感器组件150沿云台130的偏航轴转动,或者使传感器组件150沿云台130的横滚轴转动。

图4为本发明飞行器机臂收拢状态示意图。
在一些实施例中,结合图1及图4其中飞行器100包括机臂113,机臂113与机身110可转动连接,以使机臂113可以相对于机身110收拢和展开。
在一些实施例中,机臂113可以是偶数个,例如,2个,4个、6个、8个等;或者,机臂113也可以为奇数个,例如,1个,3个,5个等。
在一些实施例中,机臂113用于承载为飞行器100提供飞行动力的动力组件120。机臂113与动力组件120的数量可一一对应,每个机臂113可承载一个动力组件120。动力组件120可包括螺旋桨121以及驱动螺旋桨121转动的电机123。
在一些实施例中,动力组件120的数量与螺旋桨121的数量一一对应,每个动力组件120均包括一个螺旋桨121。螺旋桨121的数量与电机123的数量一一对应,每个螺旋桨121都由一个对应的电机123驱动。
在一些实施例中,当多个机臂113处于收拢状态时,电机123呈规则排布在特定位置。例如,当多个机臂113处于收拢状态时,机臂113上的电机123基本排列成一条直线;或者,当多个机臂113处于收拢状态时,位于机身110的同一侧的多个机臂113上的电机123朝向相同;或者,位于机身110的相对两侧的多个机臂113上的电机123朝向相反;或者当机臂113处于收拢状态时,机臂113上的动力组件120位于机身110的下方;或者,当多个机臂113处于收拢状态时,多个机臂113上的动力组件120基本排列成一条直线;或者,当动力组件120的外形为圆饼、方形、多边形等形状,多个机臂113上的动力组件120堆叠为圆筒形、方筒形、多边筒行等相应的筒形状;或者,当多个机臂113处于展开状态时,多个机臂113上的动力组件120分布在机身110的周围。
图5为本发明飞行器机臂展开状态的侧视图。
在一些实施例中,当机臂113处于展开状态时,机身110的其中一侧的动力组件120相对于机身110的高度,大于另外一相对侧的动力组件120相对于机身110的高度。例如,当机臂113处于展开状态时,因机臂113安装在机身110的高度不同或者机臂113长短的不同而使得靠近机头的两个动力组件120相对于机身110的高度大于靠近机尾的两个动力组件相对于机身110的高度;或者,靠近机尾的两个动力组件120相对于机身110的高度大于靠近机头的两个动力组件相对于机身110的高度。
在一些实施例中,多个机臂113a通过第四转轴机构113a与机身110可转动连接,使得机臂113a可相对于机身110转动,从而使得机臂113可处于展开和收拢状态。当机臂113处于展开状态时,其中一部分机臂113中的第四转轴机构113a相对于机身110的位置,高于另外一部分机臂113中的第四转轴机构113a相对于机身110的位置。
在一些实施例中,多个第四转轴在机身上的安装位置不同,例如:当机臂113处于展开状态时,位于机身110一侧的多个机臂113的第四转轴机构113a相对于飞行器100的俯仰轴或横滚轴对称设置。或者,多个机臂113的第四转轴机构113a的轴线相对于飞行器100的俯仰轴或横滚轴倾斜设置;或者,多个机臂113的第四转轴机构113a的轴线相对于机身110倾斜向下设置。
在一些实施例中,如图4所示,动力组件120还包括桨保护罩125,桨保护罩125与机臂113固定连接。动力组件120的数量与桨保护罩125的数量一一对应,例如,每个动力组件120对应围设有一个桨叶保护罩125。
在一些实施例中,当多个机臂113处于收拢状态时,多个机臂113上的动力组件120的桨保护罩125呈规则形状。例如,当多个机臂113处于收拢状态时,多个机臂113上的动力组件120的桨保护罩125基本排列成一条直线;或者,桨保护罩125的外形为圆环形状,当多个机臂113处于收拢状态时,多个机臂113上的动力组件120的桨保护罩125堆叠为圆筒形。桨保护罩125的外形也可以是方形、多边形等形状,当多个机臂113处于收拢状态时,多个机臂113上的动力组件120的桨保护罩125堆叠为方筒、多边筒等相应的筒形状。
在一些实施例中,飞行器100还包括锁定机构。例如,锁定机构与机身110固定连接,用于将机臂113锁定在展开状态,和/或将机臂113锁定在收拢状态。例如锁定机构在机身110侧设置有卡合部,在机臂113侧设置有配合部,当机臂113处于展开状态时,配合部与卡合部抵接,使得处于展开状态的机臂113不能转动,从而起到固定机臂的作用;或者,锁定机构在机身110侧和机臂113侧均设置有磁性件,当机臂113处于展开状态时,两侧的磁性件抵接并相互吸引,使得处于展开状态的机臂113不能转动。
在一些实施例中,当多个机臂113处于收拢状态时,第一转轴机构130a的轴臂131相对于机身110基本水平设置;和/或当多个机臂113处于收拢状态时,功能组件170以及传感器组件150分别位于机身110的相对两侧;和/或当多个机臂113处于收拢状态时,功能组件170以及传感器150组件分别位于机身110的机头以及机尾方向。
在一些实施例中,当多个机臂113处于收拢状态时,第一转轴机构130a的轴臂131被动力组件120阻挡至预设角度,从而使得动力组件120难以继续朝向机身110顶部转动。如图4所示,当多个机臂113处于收拢状态时,因机臂113收拢而使得动力组件120的位置处于传感器组件150及功能组件170的转动的平面上,从而使得传感器组件150及功能组件170无法随意转动。
