无人机安全防护装置以及无人机安全防护方法 技术领域
本发明涉及无人机领域，尤其涉及一种无人机安全防护装置以及相应的无人机安全防护方法。
背景技术
以往的多旋翼飞行器，一旦失控发生坠机或者操作不当撞到任何人/物，飞机上的装置很容易损坏，包括桨叶、电机、飞控，机身等等。
目前市场上无人多旋翼机的保护装置比较简单，基本上是以桨保护罩来保护飞机坠机或者操作不当引发紧急情况带来的损失，这种装置只能轻微保护飞机上个别零部件、桨叶、电机，真正坠机时起不到保护飞机上各类重要装置的作用，也不能预防由此带来的安全隐患。
因此，本领域的技术人员致力于开发一种能够很好地解决无人多旋翼机失控坠机或者操作不当带来的严重损坏以及安全隐患的技术方案。
发明内容
有鉴于现有技术的上述缺陷，本发明所要解决的技术问题是提供一种能够很好地解决无人多旋翼机失控坠机或者操作不当带来的严重损坏以及安全隐患的无人机安全防护装置。
为实现上述目的，本发明提供了一种无人机安全防护装置，包括：飞机控制器装置、与飞机控制器装置连接的一个或多个电机及桨叶装置、安装在机身内部的一个或多个安全气囊、以及传感器；其中，传感器用于感测无人机的速度，并且在感测到无人机的下落速度大于预定下落速度阈值时或者在感测到无人机的下落加速度大于预定下落加速度阈值时使得所述一个或多个安全气囊弹出。
优选地，传感器在感测到无人机的下落速度大于预定下落速度阈值时或者在感测到无人机的下落加速度大于预定下落加速度阈值时向飞机控制器装置发出提示信号，飞机控制器装置在接收到提示信号时向所述一个或多个安全气囊发出弹出指令，以使得所述一个或多个安全气囊弹出。
优选地，其中对应于各个电机及桨叶装置进行布置所述一个或多个安全气囊。
优选地，所述的无人机安全防护装置还包括：一个或多个桨叶防护网，其中一个桨叶防护网对应于一个电机及桨叶装置并且至少部分地围绕所述一个电机及桨叶装置布置。
优选地，所述一个或多个安全气囊分别布置在所述一个或多个桨叶防护网下方。

第一步骤：通过传感器感测无人机的速度；
第二步骤：在传感器感测到无人机的下落速度大于预定下落速度阈值时或者在感测到无人机的下落加速度大于预定下落加速度阈值时，使得所述一个或多个安全气囊弹出。
在本发明中，采用在无人多旋翼机机身内部(例如，机臂、中心飞盘)安装安全气囊装置，并在该安全气囊装置上安装传感器，传感器检测到飞机快速下落及飞行者操作不当引发飞机失控会立刻进入到安全保护模式，机身会立刻弹出安全气囊，保护无人多旋翼机坠机或者与任何人/物发生碰撞带来的器件算坏以及不必要的安全隐患。
以下将结合附图对本发明的构思、具体结构及产生的技术效果作进一步说明，以充分地了解本发明的目的、特征和效果。

具体实施方式
图1是根据本发明优选实施例的无人机安全防护装置的结构示意图。
具体地说，如图1所示，根据本发明优选实施例的无人机安全防护装置包括：飞机控制器装置10(例如，飞机控制器装置10中一般包含电池)、与飞机控制器装置10连接的一个或多个电机及桨叶装置20、安装在机身内部的一个或多个安全气囊30(例如，如图1所示，对应于各个电机及桨叶装置20进行布置的一个或多个安全气囊30)、以及传感器(未图示，传感器可以安装在任意适当位置)。
其中，传感器用于感测无人机的速度，并且在感测到无人机的下落速度大于预定下落速度阈值时或者在感测到无人机的下落加速度大于预定下落加速度阈值时使得所述一个或多个安全气囊30弹出。
例如，传感器在感测到无人机的下落速度大于预定下落速度阈值时或者在感测到无人机的下落加速度大于预定下落加速度阈值时向飞机控制器装置10发出提示 信号，飞机控制器装置10在接收到提示信号时向所述一个或多个安全气囊30发出弹出指令，以使得所述一个或多个安全气囊30弹出。
优选地，根据本发明优选实施例的无人机安全防护装置还包括：一个或多个桨叶防护网40，其中一个桨叶防护网对应于一个电机及桨叶装置20并且至少部分地围绕所述一个电机及桨叶装置20布置。
优选地，所述一个或多个安全气囊30分别布置在所述一个或多个桨叶防护网40下方。
在本发明中，采用在无人多旋翼机机身内部(例如，机臂、中心飞盘)安装安全气囊装置，并安装传感器，传感器检测到飞机快速下落及飞行者操作不当引发飞机失控会立刻进入到安全保护模式，机身会立刻弹出安全气囊，保护无人多旋翼机坠机或者与任何人/物发生碰撞带来的器件算坏以及不必要的安全隐患。
