请参阅图1至图3，无人机100包括螺旋桨200、电机300、电机安装座400、保护壳500、机臂600和机身700。机臂600从机身700伸出。螺旋桨200、电机300、电机安装座400和保护壳500安装于机臂600上。电机300 与螺旋桨200连接，从而为无人机100提供飞行动力。
在本实施例中，无人机100为八旋翼无人飞行器。机臂600的数量为八个，螺旋桨200、电机300、电机安装座400和保护壳500的数量均与机臂600的数量相同，每一个机臂600上对应设有一个螺旋桨200、电机300、电机安装座400和保护壳500。可以理解的，在其他实施例中，螺旋桨200、电机300、电机安装座400和保护壳500可以根据实际需求设计其他任意合适的数量、类型或排布。
在某些实施方式中，将包括电机300、电机安装座400和保护壳500的部件进行组装，得到电机组件；再将螺旋桨200、电机组件、机臂600、机身700进行组装，得到无人机100。在另一些实施方式中，将包括电机安装座400、保护壳500与机臂600的部件进行组装，得到机臂组件；再将螺旋桨200、电机300、机臂组件、机身700进行组装，得到无人机100。
请参阅图3至图5，电机安装座400包括安装结构410、连接结构420和夹持结构430。连接结构410连接于安装结构420与夹持结构430之间，安装结构410与电机300连接，夹持结构430与机臂600连接。
在本实施例中，安装结构410设于连接结构420的上端，并与电机300可拆卸连接。夹持结构430设于连接结构420的下端。安装结构410的轮廓尺寸大于连接结构420的轮廓尺寸，使得安装结构410中用于与电机300连接的部位位于安装结构410中用于与连接结构420连接的部位外部，防止连接结构420在电机300拆装时造成干涉，提高电机300维修的可操作性。
需要说明的是，本申请实施方式的描述中出现的上、下、底、顶等方位用语是电机安装座400和电机300安装于电子设备例如无人机以后，无人机100常规运行姿态为参考，而不应认为具有限制性。
可以理解的，在其他实施例中，电机安装座400也可以是任意其他合适结构，例如安装结构410从夹持结构430的机臂插入方向延伸设置，只要电机300通过电机安装座400能够安装于机臂600上即可。
请参阅图4、图6至图9，本实施例中的保护壳500套设于电机安装座400外部，用于保护电机300。具体的，保护壳500包括缓冲件510、收容结构520和支撑架530。
请参阅图4，缓冲件510套设于电机安装座400外部，并与电机安装座400可拆卸连接。当无人机100受到撞击时，缓冲件510受到冲击力后，能够吸收冲击或震动，起到良好的缓冲作用，进而提高电机300工作的可靠性，延长电机300的使用寿命。
具体的，缓冲件510包括基体511和围合体512。其中，在某些实实施方式中，基体511为板状结构，其与电机安装座400的底部抵接，用于支撑电机安装座400。可以理解的，在其他实施方式中，基体511也可以为其他任意合适结构，例如杆状架体。
请参阅图6至图9，围合体512从基体511的周缘朝向基体511一侧延伸。围合体512与基体511围合形成收容电机安装座400的收容结构520。具体的，收容结构520包括收容空间521、第一开口522和第二开口523。第一开口522和第二开口523均与收容空间521连通。电机安装座400可以从第一开口522装入收容空间521内，使得电机安装座400能够收容于收容空间521内。机臂600可以从第二开口523用于供插入收容空间521内，从而与电机安装座400连接。
在本实施例中，第二开口523呈U形，第二开口523的侧壁与底壁均与机臂600抵接，以吸收来自机臂600的冲击，减小从机臂600传递至电机安装座400的冲击力，从而进一步有效保护电机300。可以理解的，在其他实施中，第二开口523也可以为其他任意合适形状，例如方形、环形等，第二开口523的侧壁与底壁中的部分区域或全部区域也可以与机臂600间隔设置，只要机臂600能够穿设第二开口523与电机安装座400连接即可。
请参阅图6至图9，围合体512包括第一侧壁部513、第二侧壁部514和第三侧壁部515。其中，第一侧壁部513的数量为两个，两个第一侧壁部513相对间隔设置。每一个第一侧壁部513上均设有装配部5131，该装配部5131能够与电机安装座400可拆卸连接。
在本实施例中，第一侧壁部513包括第一侧壁段5132、第二侧壁段5133和弯折段5134。第一侧壁段5132从基体511的周缘朝向基体511的一侧延伸。第二侧壁段5133连接于第一侧壁段5132背离基体511的一端。
在某些实施方式中，两个第一侧壁段5132的间隔距离小于两个第二侧壁 段5133的间隔距离，以更好地与电机安装座400适配。可以理解的，在其他实施方式中，两个第一侧壁段5132的间隔距离也可以大于或等于两个第二侧壁段5133的间隔距离，只要电机安装座400能够收容于收容结构520内即可。
请参阅图6至图9，弯折段5134自第二侧壁段5133背离基体511的一端向背离围合体512的中心的方向弯折延伸，以与电机安装座400的安装结构410适配，并能够支撑安装结构410。换句话而言，弯折段5134从第二侧壁段5133的上端向背离收容空间521的一侧弯折延伸。
在本实施例中，弯折段5134与第二侧壁段5133大致垂直。可以理解的，在其他实施例中，弯折段5134与第二侧壁段5133也可以呈任意合适的角度，只要保护壳500能够套设在电机安装座400外部，起到吸收冲击或振动，以保护电机300即可。
请参阅图6至图9，装配部5131设于弯折段5134上，以将保护壳500与电机安装座400的连接。装配部5131可以是装配孔、卡槽、卡扣等任意合适的装配结构，只要能够将保护壳与电机安装座400连接固定即可。在本实施例中，装配部5131为装配孔，螺钉等紧固件穿设装配孔和电机安装座400的相应部位，实现保护壳与电机安装座400的固定。
请参阅图6至图9，作为一优选的实施方式，第一侧壁部513还包括第三侧壁段5135，以增加保护壳500对电机安装座400的包覆面积，提高缓冲效果，有效保护电机300。具体的，第三侧壁段5135自弯折段5134背离第二侧壁段5133的一端向背离基体511的方向延伸。在第三侧壁段5135的上端面高于或齐平电机安装座400的上端面，以进一步增加保护壳500对电机安装座400的包覆面积，进一步提高缓冲效果。
请参阅图6至图9，第二侧壁部514连接于两个第一侧壁部513，第二开口523设于第二侧壁部514上。第三侧壁部515连接于两个第一侧壁部513，并与第二侧壁部514间隔设置。第二侧壁部514、第三侧壁部515、基体511和两个第一侧壁部513围合形成收容结构520。
请参阅图4、图6至图9，在本实施例中，基体511、第一侧壁段5132、第二侧壁段5133、第三侧壁段5135、第二侧壁部514和第三侧壁部515均与电机安装座400间隔设置，使得保护壳500与电机安装座400之间存在间隙 800，能起到缓冲作用，有效保护电机300。
具体的，当无人机100遭到外力撞击时，由于保护壳500与电机安装座400之间存在间隙800，因而能够缓冲外力，避免了冲击力直接作用到电机安装座400上，进而使得安装在电机安装座400上的电机300，即使在恶劣的工作环境下作业，也能够保证电机300工作的可靠性，延长电机300的使用寿命。
可以理解的，在其他实施例中，基体511、第一侧壁段5132、第二侧壁段5133、第三侧壁段5135、第二侧壁部514和第三侧壁部515中的至少一个与电机安装座400抵接，只要缓冲件510能够起到缓冲作用即可。
在本实施例中，缓冲件510可以采用橡胶、发泡填充体等软性材质制成。此时，当保护壳500受到冲击时，缓冲件510发生弹性形变，能够吸收冲击或振动，从而提高电机300工作的可靠性，延长电机300的使用寿命。可以理解的，在其他实施例中，缓冲件510也可以是其他能够缓冲冲击的结构，能够起到缓冲冲击或振动的作用即可。
请参阅图6至图9，为了支撑缓冲件510，支撑架530包括承托部531、连接部532和夹持部533。
其中，承托部531与基体511抵接，用于支撑基体511。在本实施例中，承托部531为片状结构，承托部531的尺寸与基体511的尺寸相适配。可以理解的，在其他实施例中，承托部531也可以为其他任意合适的尺寸或结构，能够支撑基体511即可，本发明不限于此。
连接部532自承托部531的一端朝向围合体512弯折延伸，以与围合体512适配。夹持部533自连接部532背离承托部531的一端弯折延伸。夹持部533与围合体512连接，以夹持围合体512。
请参阅图6至图9，，夹持部533包括第一夹持臂5331和第二夹持臂5332。其中，第一夹持臂5331和第二夹持臂5332均自连接部532背离承托部531的一端弯折延伸。第二夹持臂5332与第一夹持臂5331相对设置。换句话而言，第一夹持臂5331和第二夹持臂5332分别从连接部532背离承托部531的一端朝两个相反的方向弯折延伸，以更好地支撑缓冲件510。
可以理解的，在其他实施例中，支撑架530也可以是其他任意合适结构，例如，支撑架530与缓冲件510形状适配，支撑架530包覆缓冲件510的外周壁，能够起到支撑缓冲件510的作用即可。
在本实施例中，缓冲件510与支撑架530通过嵌件成型工艺一体成型。可以理解的，在其他实施例中，缓冲件510与支撑架530也可以是独立的部件，通过胶层粘合等任意合适的连接方式进行固定。
组装时，电机安装座400从保护壳500的第一开口522装入保护壳500的收容空间521内，机臂600从保护壳500的第二开口523插入收容空间521并与电机安装座400连接。通过螺钉等紧固件将电机安装座400与保护壳500的装配部5131连接固定，实现保护壳500、电机安装座400和机臂600的组装。
上述实施方式的保护壳500、电机组件、机臂组件及无人机100，当无人机100等电子设备受到撞击时，保护壳500受到冲击力后能够吸收冲击或震动，起到良好的缓冲作用，进而提高电机300工作的可靠性，延长电机300的使用寿命。
实施例二
请参阅图3至图9，本实施例的保护壳500与实施例一的保护壳500大致相同，其区别在于，本实施例在实施例一的基础上，弯折段5134上还设有通孔部5136，以允许空气流动，从而利于电机300散热。通孔部5136与装配部5131间隔设置。
请参阅图4、图6至图9，在本实施例中，基体511、第一侧壁段5132、第二侧壁段5133、第三侧壁段5135、第二侧壁部514和第三侧壁部515间隔设置，使得保护壳500与电机安装座400之间存在间隙800，因而既能起到缓冲作用，有效保护电机300，又不会影响电机300散热。
具体的，当无人机100遭到外力撞击时，由于保护壳500与电机安装座400之间存在间隙800，因而能够缓冲外力，避免了冲击力直接作用到电机安装座400上，进而使得安装在电机安装座400上的电机300，即使在恶劣的工作环境下作业，也能够保证电机300工作的可靠性，延长电机300的使用寿命。
请参阅图5，在本实施例中，电机安装座400为中空结构，具有顶部开口440、侧部开口450以及缺口460。顶部开口440和缺口460均设于安装结构410上，侧部开口450设于连接结构420上。顶部开口440和侧部开口450均与中空结构连通，缺口460与通孔部5136对应设置。顶部开口440、中空结构、侧部开口450、间隙800、通孔部5136和缺口460形成一散热通道，电机300内部的空气能够经该散热通道排出，增加了空气流通的通道，提高了电机300的散热效率。
可以理解的，在其他实施例中，基体511、第一侧壁段5132、第二侧壁段5133、第三侧壁段5135、第二侧壁部514和第三侧壁部515的至少一个与电机安装座400抵接，只要缓冲件510能够起到缓冲作用即可。
实施例三
请再次参阅图2至图9，实施例三的保护壳500与实施例一的保护壳500结构大致相同，其区别在于，本实施例在实施例一的基础上，第三侧壁部515上设有连通收容结构520的第一贯穿开口5151，连接部532上设有连通收容结构520的第二贯穿开口5321。第一贯穿开口5151与第二贯穿开口5321对应设置，用于安装指示灯组件900。

请参阅图6和图7，在本实施例中，第一侧壁段5132具有凹陷部位5137，两个第一侧壁段5132的凹陷部位5137间隔设置，围合形成一个配合空间，以更好地与灯座910中的相应部位适配。在某些实施方式中，凹陷部位5137为弧形凹槽。
可以理解的，在其他实施例中，凹陷部位5137也可以为具有方形或其他不规则形状的凹槽，甚至凹陷部位5137可以省略，只要灯座910的相应部位能够放置于两个第一侧壁段5132之间即可。
以上，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此， 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到各种等效的修改或替换，这些修改或替换都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。
