Description

无人机 技术领域
本申请涉及一种飞行器技术领域，特别涉及一种无人机。
背景技术
无人机具有飞行姿态容易控制等优点，目前随着技术的成熟，无人机的应用范围不断扩大，特别是在一些航拍、探测等领域，无人机具有较高的普及率，通常见到的多旋翼无人机根据不同的应用场合或者不同着陆地点的不同地形，有时需要配合选用不同的起落架。但是目前的多旋翼无人机，因为起落架通常采用螺纹固定方式将起落架固定于无人机机身的底部，这样的固定方式导致起落架不能方便地拆卸和组装，费时费力，拆装过程复杂，且无人机占用空间大，不便于携带。
发明内容
本申请的目的在于提供一种无人机，能够实现起落架的快速安装和拆卸，且方便无人机的携带。
为实现本申请的目的，采取的技术方案是：
一种无人机，包括机身、起落架和连接件，连接件至少包括两个固定件，其中一个固定件与机身连接，另外一个固定件与起落架连接，其中一个固定件设有与另外一个固定件外周形状匹配的固定腔以及与固定腔连通的卡槽，另外一个固定件设有与卡槽配合的卡扣。
安装时，设有卡扣的固定件伸入另一个固定件的固定腔内，并通过卡扣与卡槽配合连接，实现机身与起落架的安装固定；拆卸时，将卡扣脱离卡槽，并将设有卡扣的固定件抽出另一个固定件的固定腔，即可实现机身与起落架的拆卸。通过在机身和起落架之间设置了连接件，使机身和起落架之间实现可拆卸连接，实现起落架的快速安装和拆卸，省时省力，且机身和起落架拆卸后，减少无人机的占用空间，方便无人机的携带。
下面对技术方案进一步说明：
进一步的是，设有固定腔的固定件与机身连接，设有卡扣的固定件与起落架连接。
进一步的是，设有卡扣的固定件与机身连接，设有固定腔的固定件与起落架连接。
进一步的是，卡扣至少包括与卡槽配合的突起部、驱动突起部伸入或脱离卡槽的按压部，按压部伸出固定腔。卡扣的按压部设置在固定腔的外部，使起落架的安装和拆卸更方便。
进一步的是，卡扣固定于第二固定件的外壁，设有固定腔的固定件为第一固定件，设有卡扣的固定件为第二固定件，突起部设有斜面，斜面由靠近第一固定件的一端向远离第一固定件的一端逐渐远离第二固定件的外壁。第二固定件插入第一固定件的固定腔时，斜面靠近第二固定件外壁的一端先贴紧固定腔的内壁，起到预紧作用，直至突起部的整个斜面扣入卡槽内，使机身和起落架之间固定得更稳固。
进一步的是，卡扣为弹簧弹片。利用弹簧弹片的弹力，使两个固定件固定在一起，也便于起落架的安装和拆卸更省力。
进一步的是，固定腔的内壁凹设有竖向设置的凹槽，设有卡扣的固定件设有与凹槽配合的凸台。通过凹槽和凸台的配合，对第一固定件和第二固定件的安装起导向和定位作用，使机身和起落架之间更快速地安装和拆卸。
进一步的是，无人机还包括驱动起落架伸长或缩短的驱动机构。使无人机根据不同飞行状态，调整起落架的俯仰，使无人机的使用更方便。
与现有技术相比，本申请具有以下有益效果：
本申请通过将设有卡扣的固定件伸入另一个固定件的固定腔内，并通过卡扣与卡槽配合连接，实现机身与起落架的安装固定；拆卸时，则将卡扣脱离卡槽，并将设有卡扣的固定件抽出另一个固定件的固定腔，即可实现机身与起落架的拆卸。通过在机身和起落架之间设置了连接件，使机身和起落架之间实现可拆卸连接，实现起落架的快速安装和拆卸，省时省力，且机身和起落架拆卸后，减少无人机的占用空间，方便无人机的携带。
附图说明

10.起落架，20.连接件，210.第一固定件，211.固定腔，212.卡槽，220.第二固定件，221.凸台，30.卡扣，310.突起部，311.斜面，320.按压部，40.驱动机构。
具体实施方式
下面结合附图对本申请的实施例进行详细说明：
如图1所示，一种无人机，包括机身(附图未标识)、起落架10和连接件20，连接件20至少包括第一固定件210和第二固定件220，第一固定件210与机身连接，第二固定件220与起落架10连接，第一固定件210设有与第二固定件220外周形状匹配的固定腔211以及与固定腔211连通的卡槽212，第二固定件220设有与卡槽212配合的卡扣30。
安装时，第二固定件220伸入第一固定件210的固定腔211内，并通过卡扣30与卡槽212配合连接，实现机身与起落架10的安装固定；拆卸时，将卡扣30脱离卡槽212，并将第二固定件220抽出第一固定件210的固定腔211，即可实现机身与起落架10的拆卸。通过在机身和起落架10之间设置了连接件20，使机身和起落架10之间实现可拆卸连接，实现起落架10的快速安装和拆卸，省时省力，且机身和起落架10拆卸后，减少无人机的占用空间，方便无人机的携带。
在本实施例中，第一固定件210与机身连接，第二固定件220与起落架10连接。无人机还可以根据实际需要将第一固定件210与起落架10连接，将第二固定件220与机身连接。
如图1所示，卡扣30固定于第二固定件220的外壁，卡扣30至少包括与卡槽212配合的突起部310、驱动突起部310伸入或脱离卡槽212的按压部320，按压部320伸出固定腔211。卡扣30的按压部320设置在固定腔211的外部， 使起落架10的安装和拆卸更方便。
突起部310设有斜面311，斜面311由靠近第一固定件210的一端向远离第一固定件210的一端逐渐远离第二固定件220的外壁。第二固定件220插入第一固定件210的固定腔211时，斜面311靠近第二固定件220外壁的一端先贴紧固定腔211的内壁，起到预紧作用，直至突起部310的斜面311扣入卡槽212内，使机身和起落架10之间固定得更稳固。
在本实施例中，卡扣30为弹簧弹片，由于弹簧弹片的弹性作用，第二固定件220插入第一固定件210的固定腔211时，突起部310会被压缩，直至突起部310移动至与卡槽212完全相对时，在弹力的作用下，使突起部310扣入卡槽212内，消除装配过程中的间隙。且弹簧弹片设有位于突起部310和按压部320之间的抵接部330，拆卸时，往下压按压部320时，，使突起部310往回缩并脱离卡槽212，之后将第二固定件220从第一固定件210内抽离即可，拆卸方便。
固定腔211的内壁凹设有竖向设置的凹槽(附图未标识)，第二固定件220外壁设有与凹槽配合的凸台221。通过凹槽和凸台221的配合，对第一固定件210和第二固定件220的安装起导向和定位作用，使机身和起落架10之间更快速地安装和拆卸。
如图1所示，无人机还包括驱动起落架10俯仰状态的驱动机构40。使无人机根据不同飞行状态，调整起落架俯仰角度，使无人机的使用更方便。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对专利申请范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本专利申请的保护范围应以所附权利要求为准。
