具体实施方式
请参阅图1至图3，本发明无人机的动力系统10一实施例，包括：电机11、固定座12以及防水透气膜13。
其中，电机11用于为无人机提供动力且设置有通气孔111。无人机采用的电机主要有有刷电机和无刷电机两种，本实施例中主要指无刷电机，如常见的2212、2018、2820、5010，KV390、KV2600等，通过电机11的转动带动螺旋桨转动，从而为无人机提供上升的动力。容易理解地，电机11在工作时产生大量的热量需要排出，而通气孔111的设置，使得电机11内部与外界实现空气流通，带出电机工作所产生的热量，进而保证了动力系统散热。在一个应用场景中，通气孔111居中设置于电机11上且沿电机11的轴向延伸，具体如图1中所示。通气孔111具体可以设置成如图1中所示的具有四个孔的样式，也可以设置成独孔、两孔、三孔、五孔、六孔等等，具体根据情况设置即可，同时，通气孔111的界面形状可以设置为如图1中所示的类扇形，当然也可以设置成圆形、多边形等等，只要能够保证无人机动力系统10的透气性即可。
固定座12用于固定电机11且设置有容置腔121和开口122，通气孔111经开口122与容置腔121连通。上述电机11通过与固定座12的连接固定在无人机上，以保证电机11的稳定性。电机11具体可以通过螺钉与固定座12连接在一起，在一些应用场景中也可以通过卡扣、螺栓、粘胶等连接。固定座12通常由具有一定强度的材质制作而成，例如可以是强度高的硬质塑料、金属等。其中的容置腔121设置在固定座12背对电机11的一侧，沿着固定座的轴向延伸，具体可以呈圆柱状、椭圆柱状等此处不做限定。开口122则设置在固定座12朝向电机11一侧，其大小、形状和位置只要满足通气孔111能够经其与容置腔121连通/部分连通即可。
防水透气膜13，用于覆盖通气孔111和/或开口122，以在允许通气孔111与容置腔121之间的气体流通的同时防止通气孔111内的水珠进入容置腔121。防水透气膜13，顾名思义，是一种既能防水同时又能透气的膜层，是一种新型的高分子防水材料。具体可以是聚四氟乙烯防水透气膜、TPU防水透气膜等。在一个应用场景中，防水透气膜13主要有三层构成，即PP纺粘无纺布、PE高分子透气膜、PP纺粘无纺布。具体根据情况选择。防水透气膜13具体可以直接固定在电机11上并覆盖通气孔111，从而在不影响通气孔111透气的同时，一定程度上避免水珠等通过通气孔111进入电机11内部以及固定座12的容置腔121中影响动力系统10的性能。在另一个应用场景中，防水透气膜111也可以固定在固定座12上并覆盖开口122进而降低水珠通过通气孔111以及开口122进入固定座12而影响固定座12的容置腔121内的构件，例如连接线等的性能。当然，防水透气膜13也可以既在电机11上设置又在固定座12上设置，以使得通气孔111以及开口122均被防水透气膜所覆盖，从而起到双重保护作用。具体地，防水透气膜13上设置有粘合胶层(图中未显示)，从而使得防水透气膜13通过粘合胶层贴附固定于电机11和/或固定座12上，且覆盖通气孔111和/或开口122。
可选地，动力系统10进一步包括压合件14，压合件14将防水透气膜13压合固定于电机11上。其中，压合件14具体设置于防水透气膜13与固定座12之间。在一个应用场景中，压合件14也可以设置在固定座12上，使其与固定座12呈一体。
可选地，压合件14包括环形压合部141以及设置于环形压合部141外围的固定部142，其中固定部142与电机11固定连接，进而使得环形压合部141将防水透气膜13压合固定于通气孔111的外围。需要指出的是，环形压合部141不会覆盖到通气孔111或者仅部分覆盖，不影响 空气通过通气孔111的贯通即可，具体地，压合件14可以是橡胶圈、环形薄片等。其中固定部142与电机11可以通过如螺钉连接等连接，也可以仅通过固定座12与电机11的连接将其夹接在电机11与固定座12之间，进而实现对防水透气膜13进一步压合。当固定部142与电机11通过螺钉等连接在一起时，在一个应用场景中，固定部142与固定座12与电机11连接处相对应，因此可通过螺钉将压合件14、固定座12一起连接在电机11上。当然，压合件14也可以与固定座12分开，单独与电机11连接。在一个应用场景中，压合件14为环形橡胶垫圈。
可选地，电机11上设置有形状与环形压合部141和固定部142对应且用于容纳环形压合部141和固定部142的凹陷部112，具体用来容纳或部分容纳压合件14。在一个应用场景中，也可以不设置凹陷部112，而直接将压合件14固定在电机11上。同时，凹陷部112的形状也不一定与环形压合部141和固定部142完全对应，只要其能够容纳环形压合部141和固定部142即可。
可选地，动力系统10进一步包括连接导线15，固定座12设置有过孔123，连接导线15与电机11连接并经过孔123延伸至容置腔121的内部，其中过孔123内进一步填充有第一防水胶。其中，连接导线15具体可以包括供电线，与电机11连接以使得电源为电机11提供电量。在过孔123内进一步填充第一防水胶可以进一步防止水从过孔123进入容置腔121中，或进入电机11中。其中，第一防水胶可以是PS胶水、PC胶水、PA胶水、PP胶水、PE胶水、橡胶胶水以及聚氨酯胶水等等。在一个应用场景中，第一防水胶是1530白胶，当然也可以是其它的防水胶，此处并不限定。在一个应用场景中，压合件14上进一步包括通孔，通孔与过孔123相对应，用来使连接导线15经过压合件14上的通孔，再经过固定座12上的过孔123进入容置腔121中。
可选地，动力系统10进一步包括设置于容置腔121内的电调模块(图中未显示)，电调模块经连接导线15与电机11电连接，并用于根据控制信号调节电机11的转速。此时，在过孔123内进一步填充第一防水胶又能够防止水进入容置腔121中对电调模块产生破坏。当然，电调模块也并不一定设置在容置腔121内，也可以设置在无人机的其它位置上。
可选地，动力系统10进一步包括灯座16，固定座12上设置有用于接收灯座16的灯座安装槽124，灯座安装槽124内进一步填充有第二防水胶。容易理解地，与固定座12上的过孔123内进一步填充第一防水胶的作用相类似，在灯座安装槽124内进一步填充第二防水胶也可以进一步防止水从灯座安装槽124进入容置腔121中，进而实现无人机动力系统10的多重防护。其中，第二防水胶可采用与第一防水胶相同的种类，具体如上述对第一防水胶的介绍，此处不再赘述。当然第二防水胶也可以为区别于第一防水胶之外的其它防水胶，此处不做限定。
通过上述实施例的实施，防水透气膜13的设置能够在不影响无人机动力系统10的透气性的同时起到主要防水作用，同时在连接导线15所穿过的过孔123内以及灯座16对应的灯座安装槽124内分别设置第一防水胶以及第二防水胶实现了进一步的防水保护，从而使得本实施例无人机动力系统10能够受到全方位的防水保护的同时，不影响其透气性。
请参阅图4，图4是本发明无人机20一实施例。其中无人机20具体可以为多旋翼无人机、固定翼无人机或者无人直升机等。本实施例中的无人机20包括如本发明无人机动力系统一实施例中的动力系统21。其中，动力系统21的具体结构以及功能等请参见上述实施例，此处不再赘述。此种无人机20因动力系统21具有良好的防水透气性能，而能够增强其在有水存在的环境中的工作性能。
请参阅图5，本发明无人机的电机组件30一实施例，包括：电机31以及防水透气膜32。其中，电机31用于为无人机提供动力且设置有通气孔311，防水透气膜32用于覆盖通气孔311。
可选地，防水透气膜32上设置有粘合胶层，防水透气膜32通过粘合胶层贴附固定于电机31上且覆盖通气孔311，并且/或者电机31组件进一步包括压合件33，压合件33将防水透气膜32压合固定于电机31上。
具体地上述电机31、防水透气膜32以及压合件33在结构与功能上均与本发明无人机动力系统一实施例中的相同，具体请参见上述实施例，此处不在赘述。
通过上述实施例的实施，本发明电机组件30在保证不影响透气性的同时，在一定程度上避免了外界环境中的水进入电机31进而影响电机的性能，从而使得电机组件30具有良好的防水性。
以上仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
