Description

一种竞速无人机用内置天线 技术领域
本实用新型涉及无人机天线技术领域，具体为一种竞速无人机用内置天线。
背景技术
无人驾驶飞机简称“无人机”，英文缩写为“UAV”，是利用无线电遥控设备和自备的程序控制装置操纵的不载人飞机，或者由车载计算机完全地或间歇地自主地操作；与有人驾驶飞机相比，无人机往往更适合那些太“愚钝，肮脏或危险”的任务。无人机竞速运动是近年新兴的科技运动，与电竞、机器人格斗一起，并称“三大新兴智能科技运动”。与传统竞速运动的平面赛道不同，无人机竞速比赛多了垂直方向这条维度，因此也被称为“3D竞速”。无人机竞速比赛使用的无人机追求极速，最高时速可超过140公里，0到100公里的加速可在1.6秒内完成，没有GPS导航和智能避障，推重比高达8比1，完全由无人机竞速飞手手动操控，因此对飞手的调校拼装、临场反应和操控技巧提出了极高的要求。
但是，现有的竞速无人机为了保障信号的接受会将天线设置在外部，但这样的设置会增加比赛时机身所承受的风阻，从而影响赛事的发挥；因此，不满足现有的需求，对此我们提出了一种竞速无人机用内置天线。
实用新型内容
本实用新型的目的在于提供一种竞速无人机用内置天线，以解决上述背景技术中提出的竞速无人机为了保障信号的接受会将天线设置在外部，但这样的设置会增加比赛时机身所承受的风阻，从而影响赛事的发挥的问题。
为实现上述目的，本实用新型提供如下技术方案：一种竞速无人机用内置天线，包括无人机翼板，所述无人机翼板包括主支撑臂，所述主支撑臂的一端 设置有机身组接块，所述主支撑臂的外表面设置有风阻气流槽，且风阻气流槽有多个，所述主支撑臂的内部设置有伸缩收纳槽，所述伸缩收纳槽的一端设置有接线端口，所述主支撑臂的另一端设置有副支撑臂，所述副支撑臂一端的上方设置有活动转轴，所述活动转轴的两侧均设置有叶片，所述活动转轴的下方设置有驱动元件，所述驱动元件的下方设置有天线卡套，所述天线卡套的内部设置有内置感应天线，所述内置感应天线的一侧设置有信号线路。
优选的，所述主支撑臂和副支撑臂均设置为中空结构，所述主支撑臂与机身组接块通过转轴转动连接。
优选的，所述主支撑臂与副支撑臂通过伸缩收纳槽连接，所述副支撑臂与活动转轴通过卡槽连接。
优选的，所述活动转轴与叶片组合连接，所述活动转轴与驱动元件固定连接。
优选的，所述天线卡套与副支撑臂通过卡槽连接，所述天线卡套与内置感应天线组合连接，所述内置感应天线与信号线路电性连接。
与现有技术相比，本实用新型的有益效果是：
1、本实用新型通过将内置感应天线安装在无人机翼板之中，之后将翼板与无人机进行组合，每个机翼的重量均相同，这样可以保障机身的平衡，同时内置化的设置减少了无人机的风阻，而且信号感应方向也是位于机翼的下方，减少了信号的接收距离，有利于控制信号的快速传递接收；
2、本实用新型通过主支撑臂外表面设置的风阻气流槽，可以无人机在飞行时将主支撑臂上的气流进行导流，减少风阻，
3、本实用新型主支撑臂与副支撑臂可以通过伸缩收纳槽进行调节控制，从而根据情况控制调节主支撑臂与副支撑臂的总长度，节省占用空间，减少无人 机的受阻面积。
