以下结合本说明书的附图，对本发明的较佳实施方式予以进一步地详尽阐述。
请参阅图3，无人机10包括机身11及电路板15(在图2中可见)。无人机还包括多个机臂16。机臂16对称设于机身11的四周。机身11开设有收容腔，电路板15收容于机身11的收容腔内。
请参阅图1及图2，本发明提供一种无人机扩展系统。无人机扩展系统包括无人机10及扩展模块20。扩展模块20可拆卸地与无人机10进行连接。当需要安装外接功能元件的时候，将扩展模块20安装在无人机10上，当不需要安装外接功能元件的时候，再将扩展模块20拆卸下来，不影响无人机10的其他使用状态。
扩展模块20包括连接板21和标准插座22。在某些实施例中，扩展模块 20还可包括支架23用于支撑外部的功能元件30。
请参阅图4，机身11的表面开设有沉槽13。具体在本实施方式中，沉槽13开设于上盖12的前端。沉槽13用于收容、固定扩展模块20。在其他实施方式中，沉槽13的开设位置还可以根据需要进行设计，在此不做限定。
沉槽13的形状与扩展模块20的连接板21形状相适配。具体在本实施方式中，沉槽13为狭长形。在其他实施例中，沉槽13的形状还可根据需要进行设计，在此不做限定。
沉槽13的底部设有安装孔132。安装孔132可以为一个或多个。具体在本实施方式中，安装孔132为两个，且对称地设于沉槽13内。可以理解，为增强机身11与扩展模块20的连接强度，安装孔132也可以为3个或4个，在此不做限定。
安装孔132用于安装与扩展模块20进行连接的安装件40。具体在本实施方式中，安装孔132为螺纹孔，安装件40是与螺纹孔进行配合的螺栓，安装件40与安装孔132的相互配合可将扩展模块20与无人机10进行紧密连接。
请参阅图1及图2，沉槽13的底部开设标准接口131。电路板15相对于标准接口131的位置处设有电连接接口151。标准接口131与扩展模块20的标准插头22相适配，以保证标准插头22能够通过标准接口131与电路板15电连接。具体地，标准接口131设于沉槽13的底部中间位置。在其他实施例中，标准接口131的位置可以根据需要进行设置，在此不做限定。
进一步地，在本实施例中，标准接口131为USB接口。可以理解的是，在其他实施例中，标准接口131还可以根据需要选取，在此不做限定。
请参阅图5，机身11还包括盖板14。盖板14可拆卸地盖设于沉槽13上，以封盖沉槽13。当需要对无人机10进行功能扩展的时候，将盖板14拆卸下来，从而可以将沉槽13裸露出来，便于对扩展模块20进行安装。当不需要使用扩展模块20进行功能扩展的时候，盖板14设置于沉槽13处，将沉槽13进行封闭，对沉槽13进行保护，保证机身11的外表面的封闭、完整。
具体在本实施方式中，盖板14与机身11卡合连接。盖板14的两端设有卡槽141。请参阅图4，沉槽13的两端相应设有卡扣133，卡槽141与卡扣 133配合连接。卡槽141与卡扣133配合卡接，方便盖板14的拆装，操作简单。
或者，盖板14的两端设有卡扣。沉槽13的两端相应设有与之配合的卡槽，卡槽与卡扣配合连接。同样可以实现盖板14与机身11的卡合连接。机身11开设沉槽13处的表面为拱形面，盖板14的表面与机身11的表面相适配。因此，盖板14使机身11表面于沉槽13位置处，能够光滑过渡，保证机身11表面的流线型，使无人机的机身11表面受到较小的空气阻力。
可以理解，在其他实施方式中，盖板14还可以通过绑定、粘接等方式实现，可拆卸设于机身11的上盖12。
请参阅图1及图2，扩展模块20包括连接板21、标准插头22及支架23。
连接板21收容于沉槽13内。连接板21的形状与沉槽13的形状相适配。具体地，连接板21的形状也为狭长形。
在本实施例中，上盖12于开设有沉槽13的位置处呈拱形，则沉槽13的表面处也为拱形面。相应地，连接板21的形状与沉槽13形状相配合，也为拱形板。连接板21与沉槽13能够完全抵接，保证连接板21能够与机身11稳定连接。
连接板21上开设有一个或多个沉孔211。沉孔211的位置与安装孔132的位置相对设置。沉孔211的个数对应安装孔132的个数，保证机身11与连接板21保持稳定连接。
具体在本实施方式中，沉孔211对称设置在连接板21的两端。沉孔211能够使得安装件40通过。例如，安装件40为螺栓时，螺栓穿过连接板21的沉孔211，并与沉槽13内的安装孔132紧密连接，从而使的扩展模块20能够可拆卸地安装在机身11上。
请同时参阅图1及图2，标准插头22设于连接板21靠近沉槽13底部的一侧面。连接板21该标准插头与沉槽13的标准接口131相对设置。电路板15收容于机身11内。电路板15相对于标准接口131的位置处设有电连接接口151。并且，标准接口131与扩展模块20的标准插头22相适配。当扩展模块20收容于沉槽13内，标准插头22通过标准接口131与电路板15电连 接。
标准插头22可以与电路板15实现电导通及\或信号连接。可以理解，标准插头22与标准接口131可以为相互配合的插头。插头可以为信号接头或电源接头。
支架23相对于标准插头22设于连接板的另一侧。具体地，支架23固定设于连接板22的上端面。
请参阅图6，支架23为L型，其中一段与连接板21固定连接，另一段则供外部应用功能元件30连接使用。
具体在本实施方式中，支架23的一端与连接板21连接，支架23的另一端的端面开设有接口。支架23为内部中空结构，能够容纳电线、电路板、传输线中的至少一种。功能元件30可安装在支架23上，通过扩展模块20与无人机10进行配合使用。
具体在本实施方式中，功能元件30为探照灯。在其他实施例中，功能元件30还可以为扩音器、声音收录器、外接摄像头、机械手接口、超声波传感器等，在此不做限定。
请参阅图6，在本实施例中，支架23与连接板21固定连接的一端设有多根加强筋231。加强筋231对称分布。加强筋231提高支架23的强度。支架23为功能元件30提供承载作用，支架23的强度较大，可以保证功能元件30能够稳定地支撑于支架23上。
在上述无人机扩展系统中，扩展模块20与机身11可拆卸连接。当需要连接扩展模块20的时候，将扩展模块20与机身11连接，即可实现与相应功能元件与无人机10连接。当不需要增加扩展模块20的时候，即可将扩展模块20拆卸下来，避免扩展模块20影响无人机10的使用。扩展模块20能够方便无人机10的连接。
并且，扩展模块20能够与无人机10的电路板电连接，扩展模块20上设有标准插头22，通过标准插头22可以与无人机的标准接口131连接。因此外界功能元件30可以通过标准插头22与标准接口131实现与无人机10的电路板电连接。因此，具有标准接头的外界功能元件30能够方便与无人机10 实现连接，便于无人机10的应用范围的扩展，有利于无人机10的标准化发展。
虽然已参照几个典型实施方式描述了本发明，但应当理解，所用的术语是说明和示例性、而非限制性的术语。由于本发明能够以多种形式具体实施而不脱离发明的精神或实质，所以应当理解，上述实施方式不限于任何前述的细节，而应在随附权利要求所限定的精神和范围内广泛地解释，因此落入权利要求或其等效范围内的全部变化和改型都应为随附权利要求所涵盖。
