如下具体实施方式将结合上述附图进一步说明本发明。
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
需要说明的是,当组件被称为“固定于”另一个组件,它可以直接在另一个组件上或者也可以存在居中的组件。当一个组件被认为是“连接”另一个组件,它可以是直接连接到另一个组件或者可能同时存在居中组件。当一个组件被认为是“设置于”另一个组件,它可以是直接设置在另一个组件上或者可能同时存在居中组件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的。
除非另有定义,本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的,不是旨在于限制本发明。本文所使用的术语“或/及”包括一个或多个相关的所列项目的任意的和所有的组合。
请参阅图1至图4,本发明实施方式的无人飞行器100包括机身10、机臂20、连接组件30以及动力组件40。本实施方式中,所述无人飞行器100为四旋翼无人飞行器,因此所述动力组件40为旋翼组件且数量为四个,四个所述动力组件40通过所述机臂20的支撑而分布于所述机身10周围的矩形区域内,且每一个所述动力组件40位于所述矩形一个顶点上。依据空气动力学的原理,为避免所述动力组件40在转动时产生扰流,相邻的所述动力组件40在工作时的旋向不同,相对的所述动力组件40的旋向相同。
当然,依据不同的需求,所述动力组件40的数量可以作合适的变化,例如所述动力组件40的数量可以为两个、三个、六个、八个、十六个等,甚至,所述动力组件40的数量可以仅为一个,相应地,所述机臂20的数量也可以依据所述动力组件40的数量而合理设置。
所述机身10为所述无人飞行器100的承载件,所述机身10上或者内部可以设置有电气安装部,所述电气安装部可以安装及承载传感器、电路板、处理器、通信模块及电池等电子元件。本实施方式中,所述机身10的为由支架搭接而成的位于所述无人飞行器100中部位置的框架,所述机臂20能够转动连接于所述机身10的侧部。可以理解,在其他的实施方式中,机身10外也可以设置有外壳,所述外壳能够保护所述机身10上或者内部设置的电子元件。此外,所述外壳的形状设计也以能够减小飞行时的空气阻力为佳,例如,所述外壳可以为流线形、圆形、椭圆形等。
依据所述无人飞行器100的应用领域的不同,所述机身10上也可以搭载其他的能够实现特定任务的负载,例如,所述无人飞行器100用于航拍时,所述机身10可以搭载配有增稳云台的拍摄设备;所述无人飞行器100用于喷洒农药时,所述机身10可以搭载药箱以及喷洒装置;所述无人飞行器100用于竞技游戏时,所述机身10可以搭载游戏设备等。
所述机臂20用于支撑所述动力组件40并使所述动力组件40以预定样式分布于所述机身10周围。所述机臂20能够转动地连接于所述机身10的侧部,因此,所述机臂20能够相对于所述机身10调整不同的位置、状态。例如,在着陆时,所述机臂20相对于所述机身10向下方转动,以为所述无人飞行器100提供支撑;在飞行时,所述机臂20相对于所述机身10向上方转动,以避免所述机臂20对所述机身10上的负载造成遮挡。应当注意,所述“上方”、“下方”以所述无人飞行器100的处于正常飞行状态为参照,“下方”为所述无人飞行器100朝向地面的方向,“上方”为所述无人飞行器100背离地面的方向,但是,由于所述无人飞行器100的状态会有变化,上述描述不应理解为对实施方式的唯一性限定。
在图示的实施方式中,所述机臂20包括主臂21以及与所述主臂21相连的支臂22。所述主臂21的一端可转动地连接于所述机身10上,另一端与所述支臂22相连。本实施方式中,所述主臂21与所述支臂22大致连接呈“T”形。
本实施方式中,所述主臂21与所述机身10之间采用丝杆、螺母配合的方式调整相对角度,另外,所述丝杆、螺母配合的方式可以使得所述支臂22相对于所述机身10能够停留在任意角度,便于依据不同的需求调整所述无人飞行器100的形状。
本实施方式中,所述主臂21的数量为两个,两个所述主臂21分别连接于所述机身10的相背两侧,每一个所述主臂21连接两个所述支臂22,两个所述支臂22同轴设置分别位于所述主臂21的两侧。当然,每一个所述主臂21两侧的所述支臂22可以一体连接,此时所述支臂22表现为一个整体的长形臂。
可以理解,所述主臂21及其对应的所述支臂22的数量也可以依据具体需求有所变化,例如,所述主臂21的数量可以为三个、四个或者更多。
图示的实施方式中,所述主臂21采用平行连杆的结构,但是,所述主臂21并不限于上述结构,任何能够转动地连接于所述机身10的结构均可适用于所述无人飞行器100,本说明书不做限制。
所述支臂22为大致呈圆柱状的长条形杆。所述支臂22的大致中部位置连接所述主臂21,所述支臂22与所述主臂21大致垂直。所述支臂22的两端分别形成有用于安装所述动力组件40的安装部221。
可以理解,所述支臂22与所述主臂21之间的连接方式并不限于图示的实施方式,例如,所述支臂22可以不与所述主臂21垂直,所述支臂22的端部连接于所述主臂21等。
本实施方式中,所述支臂22为分段式设计,所述分段式设计使得所述支臂22能够折叠,以减小所述无人飞行器100不使用时的收纳体积。所述支臂22的具体分段式设计的结构将在下文结合所述连接组件30的结构作具体介绍。

可以理解,依据所述转动部311的形状的不同,所述配合面3111以及所述侧面3112的形状可以作适当的变化,不再详细介绍。
本实施方式中,所述转动部311与所述第一段222相连的端部设有卡槽3113,所述转动部311于所述卡槽3113两侧形成耳部3114。对应地,所述第一段222具有第一凹陷部2221以及支撑凸部2222。所述第一凹陷部2221自所述第一段222的侧面垂直于第一段222的中心轴凹陷;所述支撑凸部2222凸出于第一凹陷部2221的表面,所述支撑凸部2222大致呈板状,所述支撑凸部2222的厚度小于所述卡槽3113的宽度,使得所述支撑凸部2222能够卡入所述卡槽3113,并夹持于两个所述耳部3114之间。所述转动部311通过穿过所述耳部3114以及所述支撑凸部2222的转轴3115能够转动地与所述第一段222连接。
所述转动部311上设有顶丝313,所述顶丝313穿过所述转动部311与所述转轴3115相配合,以防止所述转轴3115的轴向移动。
所述转动部311与所述第一段222之间可以设置弹性件(图未示),以使所述转动部311具有自动复位的功能。本实施方式中,所述第一连接部31未与所述第二连接部32连接时,所述弹性件使所述转动部311保持于大致与所述第一段222垂直的位置。
具体地,所述弹性件为扭簧,其套设于所述转轴3115上,一端弹性脚抵持于所述转动部311,另一端弹性脚抵持于所述第一段222。
