请参阅图1及图2,本发明实施方式的一种气压计组件10,用于无人机100。
请一并参阅图1-图4,无人机100包括中心架20、自中心架20向外延伸的机臂30、设置在机臂30上的动力组件40和设置在中心架20下侧的壳体50,壳体50形成有收容腔52,收容腔52形成有位于壳体50的底面51且连通收容腔52与外界的通孔512。
气压计组件10包括设置于收容腔52的至少一个气压计12。
本发明实施方式的气压计组件10,气压计12设置于收容腔52内,收容腔52通过通孔512与外界连通,通孔512的位置设置最大程度上远离动力组件40,提高气压计组件10的检测准确度,另外,通孔512由于受到壳体50的遮挡可以进一步减少动力组件40
产生的气流对设置在收容腔52内的气压计12的影响。
可以理解,动力组件40通过带动附近气流流动驱动无人机100运动,气流流动会导致附近的气压变化。动力组件40与壳体50分别位于中心架20相背的两侧,形成于壳体50底部的通孔512与动力组件40间隔设置,有效地减小动力组件40产生的气流对壳体50底部附近气压的影响,进而减小对收容腔52内的气压计12的影响。
具体地,气压计组件10可以包括一个气压计12,也可以包括多个气压计12。当气压计12为多个时,有助于降低数据的偶然误差,进一步地提高气压计组件10的检测准确度。例如,当气压计12的数量为四个时,所述四个气压计12所测得的数据均传输给无人机100的飞行控制器,飞行控制器会对这些数据进行融合处理,具体的可以是求平均值,或者剔除异常值后进行平均,等等。另一方面,设置多个气压计12为冗余设计考虑,例如,当其中一个气压计12故障时,其他气压计12正常工作也可以使得气压计组件10仍然可以检测到一个较为合适的气压值。
请参阅图1及图4,在某些实施方式中,动力组件40包括电机42和旋翼44,旋翼44与电机42连接,电机42驱动旋翼44旋转,旋翼44的转轴H基本垂直于壳体50的底面51。基本垂直是指转轴H与壳体50的底面51并非完全垂直,而是两者之间形成的角度基本接近90°,且四个转轴H的交点位于无人机100的上方,如此设计使得每一个旋翼44的旋转平面均是从机臂30的端部朝向中心架20方向稍稍向下倾斜,从而使四个旋翼44各自转动产生的气流稍稍向外倾斜而非垂直向下,进而使得四个旋翼44转动产生的气流在中心架20的下方的辐射区域更广而增加无人机10飞行的稳定性。
如此,电机42驱动旋翼44旋转为无人机100提供动力,旋翼44旋转时,旋翼44附近的空气流速快,形成负压,旋翼44的转轴H基本垂直于壳体50的底面51,使得壳体50的底面51最大程度上远离旋翼44,壳体50的底面51附近的气压基本不受旋翼44转动的影响,又由于收容腔52通过设置在壳体50底部的通孔
512与外界空气连通,使得旋翼44产生的气流对设置在收容腔52内的气压计12的影响较小。
请参阅图1及图2,在某些实施方式中,壳体50还形有电池仓53。
如此,壳体50设置在中心架20下侧,电池置于电池仓53内,由于电池自重较大,可降低无人机100的重心,有助于使得无人机100飞行更加平稳。
请参阅图2及图4,在某些实施方式中,壳体50包括:
内框板54,内框板54包括:
竖直设置的中隔板542;
设置中隔板542前侧的前盖安装板544;
设置在中隔板542底端的底盖安装板546,
设置在前盖安装板544上的前盖55;和
设置在底盖安装板546上的底盖56,底盖56包括壳体50的底面51;
收容腔52形成于底盖56与底盖安装板546之间或底盖56与底盖安装板546之间和前盖55和前盖安装板544之间。
如此,收容腔52通过底盖56上的通孔512与外部空气连通,气压计12可设置在底盖56与底盖安装板546之间,也可以在底盖56与底盖安装板546之间和前盖55和前盖安装板544之间各设置至少一个气压计12,气压计12受旋翼44产生的气流的影响较小。
具体地,收容腔52包括形成于底盖56与底盖安装板546之间的第一子腔522和设置于前盖55和前盖安装板544之间的第二子腔524。第一子腔522和第二子腔524连通,可仅在第一子腔522内设置至少一个气压计12,也可以仅在第二子腔524内设置至少一个气压计12,还可以在第一子腔522和第二子腔524内各设置至少一个气压计12。
当然,在其他实施方式中,第一子腔522和第二子腔524也可以不连通,此时仅在第一子腔522内设置至少一个气压计12。
在某些实施方式中,电池仓53的数目为两个分别位于中隔板
542两侧。
如此,两个电池仓53使得无人机100可同时搭载两个电池,有助于延长无人机100的续航时间,提升用户体验。两个电池仓53分别位于中隔板542的两侧使得壳体50的重心接近壳体50的几何中心,有助于提高无人机100的飞行稳定性。两个电池间隔设置,可降低两个电池之间的热传导作用,有助于避免电池温度过高。
在某些实施方式中,无人机100包括设置在前盖安装板544与前盖55之间的电池管理系统60;
前盖55与前盖安装板544和中心架20密封连接。
如此,前盖55与前盖安装板544和中心架20密封连接使得电池管理系统60免受动力组件40产生的气流的冲击,有助于保护电池管理系统60。另外,形成于前盖安装板544与前盖55之间的收容腔52仅通过通孔512与外部大气连通,减少动力组件40产生的气流对设置在收容腔52内的气压计12的影响。
具体地,电池管理系统60可用于监测电池的状态或对电池进行充放电管理。例如,电池管理系统60可以获取电池的电压、电流和温度等参数,并对这些参数进行管控。
在某些实施方式中,前盖安装板544的与前盖55相对的一面上设置有环绕前盖安装板544周缘的前盖密封槽(图未示),前盖密封槽内填充有前盖防水胶圈(图未示),前盖防水胶圈连接前盖55和前盖安装板544。
如此,密封前盖55和前盖安装板544,避免灰尘或/及水等杂质通过前盖55和前盖安装板544之间的间隙进入前盖55和前盖安装板544之间,保护设置在前盖55和前盖安装板544之间的元器件,例如电池管理系统60。
具体地,前盖防水胶圈可以采用防水的弹性硅胶制成。
在某些实施方式中,无人机100包括设置在底盖安装板546与底盖56之间的电路元件;
底盖56与底盖安装板546密封连接。
如此,底盖56与底盖安装板546密封连接,可避免灰尘或/及水等杂质通过底盖56和底盖安装板546之间的间隙进入底盖56
和底盖安装板546之间对设置在底盖安装板546与底盖56之间的电路元件造成影响。
在某些实施方式中,底盖安装板546的与底盖56相对的一面上设置有环绕底盖安装板546周缘的底盖密封槽(图未示),底盖密封槽内填充有底盖防水胶圈(图未示),底盖防水胶圈连接底盖56和底盖安装板546。
如此,密封底盖56和底盖安装板546,避免灰尘或/及水等杂质通过底盖56和底盖安装板546的间隙进入底盖56和底盖安装板546之间,保护设置在底盖56和底盖安装板546之间的电路元件,例如气压计12。
具体地,底盖防水胶圈可以采用防水的弹性硅胶制成。
在某些实施方式中,壳体50还包括设置在通孔512内的滤网57。
如此,避免灰尘或/及水等杂质通过通孔512进入收容腔52,有助于保持收容腔52洁净,延长收容腔52的清理周期,保护设置在收容腔52内的元器件,例如气压计12、电池管理系统60等。
具体地,滤网57为防水透气网。如此,在阻止灰尘或/及水等杂质通过通孔512进入收容腔52的同时,收容腔52保持与外界大气连通,使设置在收容腔52内的气压计组件10可实时地检测气压。
在某些实施方式中,无人机100包括超声波组件70,滤网57为超声波组件70的底部装设的滤网57。
如此,通孔512使得超声波组件70可发射超声波至壳体50外和接回传的收超声波。
具体地,超声波组件70设置在收容腔52内,发射和接收超声波用于测距。超声波从通孔512通过。超声波组件70的底部设置滤网57用于阻止灰尘或/及水等杂质进入。
在某些实施方式中,至少一个气压计12设置在前盖55与前盖安装板544之间和/或底盖56与底盖安装板546之间。
如此,气压计12设置在前盖55与前盖安装板544之间和/或底盖56与底盖安装板546之间,使气压计12检测气压时,受旋
翼44产生的气流的影响较小。
可以理解,可以设置一个或者多个气压计12在前盖55与前盖安装板544之间。也可以设置一个或多个气压计12在底盖56与底盖安装板546之间。还可以在前盖55与前盖安装板544之间设置一个或多个气压计12,同时也在底盖56与底盖安装板546之间设置一个或多个气压计12。
请一并参阅图1-图4,本发明实施方式的一种无人机100包括:
中心架20;
自中心架20向外延伸的机臂30;
设置在机臂30上的动力组件40;
设置在中心架20下侧的壳体50,壳体50形成有收容腔52,收容腔52形成有位于壳体50的底面51且连通收容腔52与外界的通孔512;和
上述任一实施方式的气压计组件10,气压计组件10设置在收容腔52内。
本发明实施方式的无人机100,气压计12设置于收容腔52内,收容腔52通过通孔512与外界连通,通孔512的位置设置最大程度上远离动力组件40,提高气压计组件10的检测准确度,另外,通孔512由于受到壳体50的遮挡可以进一步减少动力组件40产生的气流对设置在收容腔52内的气压计12的影响。
