为使本发明实施例的目的、技术方案和优点更加清楚，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作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。
图1是本发明实施例一提供的脚架组件的结构示意图。图2是图1中I处的局部放大示意图。图3是图1中的脚架组件的爆炸示意图。图4是图3中II处的局部放大示意图。如图1至图4所示，本实施例的脚架组件应用在无人飞行器上，具体包括用于与无人飞行器的机体连接的固定组件20和可拆卸地连接在固定组件20上的脚架单元10，固定组件20和脚架单元10二者其中之一具有插入端1，其中另一具有可使插入端1插入的空腔2，插入端1设有卡接部11，空腔2设有可与卡接部11卡接和解除卡接的卡扣组件21，插入端1通过卡设于卡扣组件21上从而固定于空腔2中。
其中，脚架组件的脚架单元10用于支撑在无人飞行器的机体中下端，并在无人飞行器起降的时候，对无人飞行器的机体进行支撑或者缓冲，避免无人飞行器翻倒或者因冲击力过大而造成损坏。脚架单元10为可拆卸式，这样在进行运输或者存储时，脚架单元10可从机体上取下，以减少无人飞行器的占用空间。为了实现脚架单元10与机体之间的可拆卸连接，在机体上连接有固定组件20，固定组件20和脚架单元10之间可以通过卡合的方式连接在一起。
具体的，可以让脚架单元10和固定组件20的其中之一设置有空腔2，而另一个设置有可插入该空腔2中的插入部1。在空腔2中设置有卡扣组件21，而插入部1上也相应设置有卡接部11。卡接部1可以卡在卡扣组件21上，或者从卡扣组件21中脱出。当卡接部1卡在卡扣组件21上时，插入部
1和空腔2之间具有连接，此时可以实现脚架单元10和固定组件20之间的卡合连接；而卡接部11从卡扣组件21中脱出时，插入部1和空腔2之间的连接解除，插入部1可自由地从空腔2内取出，完成脚架单元10和固定组件20之间的拆卸。这样通过卡扣组件21和卡接部11之间卡合状态的切换，即可分别完成脚架单元10和固定组件20之间的连接以及拆卸。
通常的，插入部1既可以位于脚架单元10上，也可以位于固定组件20上，其具体设置方式可根据脚架组件的具体结构而定。一般的，根据用户的使用习惯，可以将插入部1设置在脚架单元10上，而空腔2位于固定组件20上。以下如无特殊说明，均以插入部1位于脚架单元10，而空腔2位于固定组件20上为例进行说明。而插入部1位于固定组件20上，空腔2位于脚架单元10上时，脚架组件和前述情况具有相似的结构，此处不再赘述。
作为一种可选的实施方式，卡接部11包括可与卡扣组件21固定的固定槽111。固定槽111具有相互平行的两侧槽壁，从而可将卡扣组件21卡设在两侧槽壁之间。当卡扣组件21卡入固定槽111中时，卡扣组件21在平行于插入部1插入方向的两个相对方向上均得到槽壁的固定，因而在这两个方向上均无法发生位移。这样，固定槽111不但能够实现和卡扣组件21的卡接，还起到了对卡扣组件21的限位作用，让脚架单元10和固定组件20之间牢固地连接并固定在一起。
进一步的，固定槽111的槽口方向一般与插入端1的插入方向呈角度设置。由于槽口方向与插入端1的插入方向是不同方向，所以固定槽111和卡扣组件21卡合时，如果插入端1和空腔2之间有运动趋势，卡扣组件21会抵设在固定槽111的槽壁上，以阻止插入端1与空腔2之间的相对运动，达到连接和限位效果。其中，固定槽111的槽口方向可以与插入端1的插入方向垂直，以达到较好的限位效果。
作为一种较佳的实施方式，当插入端1设置在脚架单元10上时，脚架单元10的插入空腔内的部位可为直杆，例如是圆形直杆或者椭圆形直杆等。此时，空腔2相应的为圆筒状或者椭圆状的直筒，固定槽111为在直杆的杆身上沿周向开设的环形槽。这样固定槽111与卡扣组件21之间能够形成面积较大的接触面，限位效果较佳。
为了实现与插入端1之间的卡接，卡扣组件21可以采用多种方式实现卡
合，例如弹性卡接、转动卡接或者滑动卡接时。例如，当采用弹性卡接方式时，卡扣组件21可为弹性卡扣组件，弹性卡扣组件的弹性位移方向和脚架单元10的插入方向呈角度设置。这样在安装或拆卸时，可以利用外力操控弹性卡扣组件移动，使其与卡接部11脱开，并将插入端1从空腔2中取出或者使插入端1进入至空腔2的预设位置；而撤去外力后，弹性卡扣组件在自身弹力作用下会恢复至与卡接部11卡合的位置，并实现插入端1和空腔2的卡接锁定。
此外，当采用转动卡接或者滑动卡接方式时，可以以插入端1的插入方向作为轴线方向，让卡扣组件21绕着该轴线旋转，并在旋转至不同位置时实现与卡接部11之间的卡合锁定或者释放。而采用滑动卡接方式时，可设置与插入端1插入方向垂直的滑槽与可沿滑槽运动的滑动件，滑动件滑动至不同位置时，同样可实现卡接部11和卡扣组件21之间的卡合锁定或者解锁。
当卡扣组件21为弹性卡扣组件时，作为一种可选的实施方式，弹性卡扣组件可包括弹性件，弹性件为自由状态时，弹性卡扣组件卡设在固定槽111内；弹性件为受力状态时，弹性卡扣组件与固定槽111脱离。弹性件可以为弹簧、扭簧或者其它可产生弹性形变的物体。这样弹性件可以在外力或者自身弹力作用下实现不同卡合状态的切换。本实施例中，以弹性件为扭簧211为例，对卡扣组件21和卡接部11之间的卡接结构，以及插入端1和空腔2之间的连接固定过程进行详细说明。
图5是图4中卡扣组件的放大示意图。如图1至图5所示，当弹性件为扭簧211时，为了传递扭簧211的作用力，扭簧211包括有第一扭臂2111和第二扭臂2112，第一扭臂2111与空腔2的位置相对固定，第二扭臂2112可卡入卡接部11。因为扭簧211处于不受力的自由状态时，第一扭臂2111和第二扭臂2112之间具有一个相对固定的角度，此时，可将第一扭臂2111与第二扭臂2112之间的角度设置成当第一扭臂2111与空腔2相对固定时，第二扭臂2112刚好卡入固定槽111内，或者其它结构的卡接部上，这样第二扭臂2112可以与固定槽111相互卡合，以完成限位和锁定。当想要解除卡接部11和第二扭臂2112之间的卡合状态，可施加外力让第二扭臂2112张开，使第一扭臂2111与第二扭臂2112之间的角度增大，并从固定槽111等卡接部中脱离，完成解锁。此时，扭簧211会因为弹性形变而产生弹力，解除外力
后，第二扭臂2112就会在扭簧211的弹力作用下张紧，并回复至和卡接部11卡合的位置。
其中，可选的，空腔2的腔壁上开设有固定孔22，第一扭臂2111的末端设置有弯折部2111a，弯折部2111a穿设在固定孔22中。这样即可完成第一扭臂2111与空腔2之间的固定。
为了使扭簧211的弹力方向作用于卡接部11，脚架组件还包括有与空腔2相对固定的固定柱212。一般的，固定柱212的方向与插入端11的插入方向保持一致，这样扭簧211可套设在固定柱212上，且第二扭臂2112绕固定柱212转动。此时，扭簧211的弹力方向与固定柱212的方向垂直或者近似垂直，并能够带动第二扭臂2112回复至原来的卡合位置，完成与卡接部11的卡合。
一般的，为了减小固定组件20或者脚架单元10的总体尺寸，扭簧211以及固定柱212一般均设置在空腔2中。为了让用户能够较为方便地对第二扭臂2112施加外力，第二扭臂2112的末端伸出空腔2，并形成扳动手柄2112a。此时，用户通过控制扳动手柄2112a，即可实现对第二扭臂2112的移动控制，完成卡接部11与卡扣组件21之间的卡合或者脱离卡合。
本实施例中，空腔2设置在固定组件20上时，为了连接在无人飞行器的机体和脚架单元10之间，固定组件20包括连接板201和固定座202，连接板201和机体连接，而固定座202可拆卸地设置在连接板201的底部，并和连接板202共同围成空腔2，固定座202具有可使脚架单元10穿过的定位孔2021。其中，固定座202和连接板201之间可以通过紧固件进行连接，也可以通过卡接等方式实现两者之间的可拆卸连接。
固定组件20固定在机体上之后，如果想要安装脚架单元10，则可将脚架单元10的插入端1穿过定位孔2021，并伸入至空腔1内。随后，插入端1上的卡接部11即可与空腔2内的卡扣组件21完成卡合或脱离卡合。
为了使插入空腔2内的插入端1与空腔2之间保持固定，避免两者之间产生摇晃或松动，固定座202具体可以包括支撑板2022和两端开口的导向筒2023，定位孔2021开设在支撑板2022上，导向筒2023的一端与支撑板2022的底部连接，且导向筒2023的内腔和定位孔2021连通，用于使脚架单元10经由导向筒2023插入空腔2内。导向筒2023的形状可与插入端1的形状相
匹配，且与插入端1之间的旷量较小，这样插入端1进入空腔2后，插入端1的侧壁和导向筒2023的内壁之间结合较为紧密，以将插入端1牢固固定在空腔2中，固定组件20和脚架单元10之间不会产生松动和摇晃。
此外，由于固定座202包括有支撑板2022，所以支撑板2022的顶面可和连接板201共同围成空腔。这样，卡扣组件21可设置在支撑板2022的顶面上。由于卡扣组件21位于空腔2的靠近脚架单元10的一侧，所以空腔2的卡扣组件21和插入部1的卡接部11之间的卡合位置与插入部1的末端之间距离较远，而脚架单元10的插入部1与固定组件20之间主要通过插入部1的末端以及卡合部位这两个位置进行固定，这两个位置之间的间距较大时，整体结构较为稳定，不易损坏或松脱。
在前述实施方式的基础上，当插入端1在脚架单元10上，且插入端1为直杆时，作为一种优选的实施方式，直杆的外侧壁上还设有至少一个凸起12，凸起12在直杆的横截面方向形成不对称结构，固定组件20的底面设置有至少一个与凸起相匹配的插槽203。此时，由于凸起12在直杆上为不对称设置或者不对称形状，所以当直杆插入固定组件20的空腔2中时，如果脚架单元10从错误的方向插入，则会因为插槽203的位置和形状与凸起12不匹配而无法插入空腔2之中。这样可以通过凸起12和插槽203所组成的防呆结构，保证脚架单元10和固定组件20之间按照正确的方向实现连接，避免脚架单元10因面向错误的方向插入而导致无人飞行器整体装配错误。
此外，需要说明的是，上述防呆结构中，是脚架单元10上设置插入端1，而空腔2位于固定组件20上。实际上在脚架单元10上设置空腔2，而固定组件20上设置插入端1时，也可以采用类似的凸起和插槽构成防呆结构，以使脚架单元10和固定组件20按照正确的方向插入卡合。
本实施例中，脚架组件应用在无人飞行器上，具体包括用于与无人飞行器的机体连接的固定组件和可拆卸地连接在固定组件上的脚架单元，固定组件和脚架单元二者其中之一具有插入端，其中另一具有可使插入端插入的空腔，插入端设有卡接部，空腔设有可与卡接部卡接和与卡接部解除卡接的卡扣组件，插入端通过卡设于卡扣组件上从而固定于空腔中。这样可以通过卡接方式实现脚架单元和无人飞行器的可拆卸连接，当无人飞行器需要运输或存放时，可将脚架单元拆下，以节省无人飞行器的整体占用空间。
图6是本发明实施例二提供的一种无人飞行器在安装有脚架单元时的结构示意图。图7是本发明实施例二提供的无人飞行器在另一方向上的结构示意图。图8是本发明实施例二提供的无人飞行器在脚架单元被拆卸后的结构示意图。如图6至图8所示，本实施例中，无人飞行器200包括机体101和如前述实施例一所述的脚架组件100，脚架组件100中的固定组件20与机体101相连，脚架组件101中的脚架单元10与固定组件20连接时，脚架单元10支撑在机体101的下方，且脚架单元10可从固定组件20上取下，以便于运输存放。其中，脚架组件100的结构、功能和工作原理均已在前述实施例一中进行了详细说明，此处不再赘述。
具体的，脚架组件100中的固定组件20可以设置在机体101的侧面或者底部，而脚架单元10和固定组件20可拆卸的连接，以支撑在机体101的下方或者侧下方。脚架组件100中的脚架单元10可以通过卡接方式与固定组件20相连，并在运输或者存储时从固定组件20上拆下，以和机体101分开存放。
本实施例中，无人飞行器包括机体和脚架组件，脚架组件中的固定组件与机体相连，脚架组件中的脚架单元与固定组件连接时，脚架单元支撑在机体的下方。这样脚架组件中的脚架单元以可拆卸的方式和机体相连，在无人飞行器需要运输或存放时，脚架单元可从固定组件上取下，以节省无人飞行器的占用空间。
