可以理解的,锁紧组件432的数量可以根据实际需求进行设计,例如一个、两个、三个或者更多,能够从通孔4311的径向锁紧机臂300即可。当锁紧组件432的数量为多个时,多个锁紧组件432沿通孔4311的轴向间隔设置,以有效夹紧机臂300,保证机臂300与电机安装座400连接的可靠性。请参阅图7和图8,在本实施例中,锁紧组件432的数量为两个。
请参阅图7和图8,定位孔部433贯穿内表面4317与外表面4318,并与通孔4311连通。机臂300上设置有与定位孔部433对应设置的插孔310,结合件例如销轴穿设定位孔部433和插孔310,将机臂300与电机安装座400固定,防止机臂300沿夹持部431的轴向发生串动。可以理解的,在其他实施例中,结合件也可以是螺栓等任意其他合适的部件,能够穿设定位孔部433和插孔310,避免机臂在夹持部431的轴向发生串动即可。
具体的,定位孔部433包括第一凹槽4331和第二凹槽4332。其中,第一凹槽4331位于夹持部431的第一自由端4313,第二凹槽4332位于夹持部431的第二自由端4314。第一凹槽4331与第二凹槽4332相对设置,形成定位孔部433。
可以理解的,定位孔部433的数量可以根据实际需求设计不同数量,例如一个、两个、三个或者更多。当定位孔部433的数量为多个时,多个定位孔部433沿通孔4311的轴向间隔设置,连接件穿设不同位置的定位孔部433,能够实现调整电机安装座400与机臂300的安装位置。请参阅图7和图8,在本实施例中,定位孔部433的数量为两个,两个定位孔部433沿通孔4311的轴向间隔设置。
请参阅图5至图8,作为优选的实施方式,夹持结构430还包括开槽434,既能够使夹持结构430稳定地夹持机臂300,又能够节省原材料,减轻无人机100的整机重量,提高续航时间。开槽434设于夹持部431上,并与通孔4311连通。具体的,开槽434贯穿夹持部431的内表面4317和外表面4318,且开槽434位于夹持部431朝向安装结构410的一侧。
在本实施例中,安装结构410、连接结构420和夹持结构430为一体成型。在其他实施例中,安装结构410、连接结构420和夹持结构430也可以为独立的部件。
组装时,将机臂300插入电机安装座400的通孔4311上,将机臂300的插孔310与电机安装座400的定位孔部433对应,通过销轴等结合件穿设插孔310和定位孔部433,对机臂300进行轴向限位。通过螺丝等紧固件锁紧第一锁紧部4321和第二锁紧部4322,使得通孔4311的孔壁与机臂300的外表面紧密接触,实现对机臂300的周向限位,从而完成机臂300与电机安装座400的组装。通过连接件将电机500底部与安装部412连 接,以将电机500固定在电机安装座400上,即完成电机500、电机安装座400和机臂300的组装。
当电机500发生故障时,松开连接电机安装座400的安装部412与电机500的连接件,即可解除安装部412与电机500的连接,即可快速的将出现故障的电机更换为备用的电机或者快速更好电机中出现故障的部件,无需将电机安装座400与电机500组成的整体从机臂300上拆下或拆下电机安装座400上连接的其他零部件,有效简化了电机500维修过程,维修方便,提高了维修效率,并且也提升了用户的体验感。
本实施例提供的电机安装座400、电机组件、机臂组件及无人机,由于电机安装座400的安装部412与电机500可拆卸连接,夹持结构430套设在机臂200上,当电机500发生故障需要维修时,解除安装部412与电机500的连接,无需将电机安装座400与电机500组成的整体从机臂200上拆下或拆下电机安装座400上连接的其他零部件,即可快速的将出现故障的电机500更换为备用的电机500或者快速更好电机500中出现故障的部件,有效简化了电机500维修过程,提高了维修效率,结构简单,并且也提升了用户的体验感。
实施例二
请再次参阅图2至图8,实施例二的电机安装座400与实施例一的电机安装座400结构大致相同,其区别在于,本实施例在实施例一的基础上,夹持部431的内部还设有定位结构440,以防止机臂300沿夹持部431的周向转动。
具体的,请参阅图6和图7,定位结构440包括第一定位键441、第二定位键442和第三定位键443。在本实施例中,第一定位键441、第二定位键442和第三定位键443沿夹持部431的周向依次间隔设置。
在某些实施方式中,第一定位键441、第二定位键442和第三定位键443均为沿夹持部431的轴向延伸的凸条结构。在其他实施方式中,第一定位键441、第二定位键442和第三定位键443也可为沿夹持部431的轴向设置且彼此分隔的多段结构,只要能够防止机臂300沿夹持部431的周向转动即可。
可以理解的,在其他实施例中,第一定位键441、第二定位键442和第三定位键443可以根据实际需求设计为任意其他合适结构,例如设计为沿夹持部431的周向延伸的多个同心环状凸起等。
请参阅图4、图6和图7,在本实施例中,机臂300的一端设有第一开口320和第二开口330。第一开口320与第一定位键441配合,第二开口330与第三定位键443配合。锁紧组件432通过紧固件使得通孔4311的直径逐渐减小。当通孔4311的直径减小至第二定位键442抵接机臂时,继续锁紧锁紧组件432,此时,第二定位键442会施加 机臂300一沿通孔4311径向向内的作用力,使得夹持部431能够稳固地夹持机臂300,提高无人机100飞行时的安全性。
可以理解的,在其他实施例中,定位结构440也可以根据实际需求设计为其他任意合适结构,例如在夹持部431上设计第一开口和第二开口,机臂300上相应设置与第一开口配合的第一定位键以及与第二开口配合的第三定位键,只要能够防止机臂300沿周向转动即可。
第一定位键441、第二定位键442和第三定位键443可以根据实际需求设于夹持部431的内表面4317的任意合适位置。请参阅图6和图7,在本实施例中,第二定位键442设于夹持部431的周向的中部,第一定位键441和第三定位键443对称设置于第二定位键442的两侧。
为了进一步保证机臂300稳固地安装于夹持部431上,第一定位键441和第三定位键443关于夹持部的中心对称,第一定位键441和第三定位键443对称设置于第二定位键442的两侧。
请参阅图6和图7,由于第二定位键442所在位置承受的力大于夹持部431的其他位置所承受的力,因而,第二定位键442设计为由包括至少两个间隔平行且沿夹持部431的轴向延伸的凸条组成,以增加第二定位键442的强度,避免因第二定位键442损坏,而需要更换电机安装座400。在本实施例中,第二定位键442由两个凸条组成,第一定位键441和第三定位键443均由一个沿夹持部431的轴向延伸的凸条组成。
可以理解的,在其他实施例中,第一定位键441、第二定位键442和第三定位键443的形状可以根据实际需求设置为其他结构,例如环状凸起、块状凸起、柱状凸起或者弧状凸起结构。
组装时,将机臂300插入电机安装座400的通孔4311上,第一定位键441、第三定位键443分别对应第一开口320和第二开口330,机臂300的插孔310对应电机安装座400的定位孔部433,通过销轴等连接件穿设插孔310和定位孔部433,对机臂300进行轴向限位。通过螺丝等紧固件锁紧第一锁紧部4321和第二锁紧部4322,使得通孔4311的孔壁与机臂300的外表面紧密接触,实现对机臂300的周向限位,从而完成机臂300与电机安装座400的组装。通过连接件将电机500底部与安装部412连接,以将电机500固定在电机安装座400上,即完成电机500、电机安装座400和机臂300的组装。
实施例三
请参阅图2、图3、图5、图6和图7,无人机在飞行作业时,电机容易受到强烈撞击而遭到损坏。为了吸收冲击或振动,避免电机因遭受撞击而损坏,本实施例在实施例一的基础上,电机安装座400还包括锁固结构450,锁固结构450设于承载部411上。 该锁固结构450与套设于电机安装座400的外部的电机保护壳800连接。
具体的,请参阅图5至图7,锁固结构450包括第一板体451和锁固部452。其中,第一板体451自承载部411背离中心的一侧向外延伸。锁固部452设于第一板体451背离承载部的一端。锁固部452可以根据实际需求设计为锁固孔、卡槽、卡扣中的至少一种结构。在本实施例中,锁固部452为锁固孔。螺丝等部件穿设电机保护壳800上的相应部位和锁固孔,将电机保护壳800固定于电机安装座400的外部。
请参阅图5和图7,作为优选的实施方式,为了加强锁固结构450的强度,锁固结构450还包括补强部453,其连接于锁固部452与承载部411。补强部453可以根据实际需求设计为任意合适的形状,例如弧形、方形或其他不规则形状等。
在本实施例中,锁固结构450和承载部411为一体式设计。可以理解的,在其他实施例中,锁固结构450和承载部411也可以是独立部件。
锁固结构450的数量可以根据实际需求设计为任意合适的数量,能够将电机安装座400和电机保护壳800固定即可。在本实施例中,锁固结构450的数量为两个,两个锁固结构450对称设置于安装结构410的相对两侧,以使电机保护壳800稳定地固定在电机安装座400上。
请参阅图7,锁固结构450与承载部411围合形成侧缺口454。当电机保护壳800安装于电机安装座400上时,侧缺口454能够允许空气流通,将电机安装座400内的空气排出,从而提高了电机的散热效率。
实施例四
请再次参阅图2、图3、图5、图6和图7,实施例四的电机安装座400与实施例三的电机安装座400结构大致相同,其区别在于,本实施例在实施例一的基础上,本实施例在实施例三的基础上,夹持结构430还包括装配部435,其设于夹持部431背离安装结构410的一侧,用于安装无人机100的发光组件900。
