第二种可拆卸连接方式:参见图13所示,所述第一连接部23包括插接部233,插接部233上设有第一紧固孔232。所述第二连接部15包括与插接部233相适配的插槽154,插槽154的两个侧壁设有与所述第一紧固孔232相适配的第二紧固孔152,第二连接部15还包括与所述第二紧固孔152以及所述第一紧固孔232相适配的紧固件153。可选地,第一紧固孔232和第二紧固孔152可以采用螺孔,紧固件153可采用螺钉。
实际应用中,第二防护组件20需要展开时,将第一杆件21的活动部22相对相邻的两个所述第一防护组件10中的第一者的所述转轴14沿远离旋翼组件91的方向转动,带动所述第一杆件21转动至展开状态,将第一杆件21的第一连接部23的插接部233插接在对应的第二连接部15的插槽154内,并使第一紧固孔232与对应的插槽154的第二紧固孔152位于同轴位置,再通过对应的所述紧固件153穿设在处于同轴位置的第二紧固孔152和第一紧固孔232中,将第一杆件21的第一连接部23与对应的第二杆件13的第二连接部15相互连接,从而使第二防护组件20处于展开状态,如图5所示。
第二防护组件20需要折叠时,先将紧固件153从对应的第二紧固孔152和第 一紧固孔232中取出,使紧固件153脱离对应的所述第二紧固孔152和所述第一紧固孔232。此时插接部233可以相对插槽154移动,使得第一紧固孔232的轴向与对应的第二紧固孔152的轴向相错开。再将第一杆件21的活动部22相对相邻的两个所述第一防护组件10中的第一者的所述转轴14沿靠近旋翼组件91的方向转动,带动所述第一杆件21转动至折叠状态,从而使第二防护组件20处于折叠状态,如图6所示。
参见图7、图8、图14和图15所示,在一些可选的实施例中,所述第二杆件13的第一端的连接头17设有凹槽部131,所述转轴14设于所述凹槽部131内,第一杆件21的活动部22部分卡接于该凹槽部131内并转动连接于该转轴14。第一杆件21的活动部22远离所述第一杆件21的端部形成有限位部221。所述活动部22相对相邻的两个所述第一防护组件10中的第一者的第二杆件13的转轴14转动,带动所述第一杆件21转动至展开状态时,所述限位部221抵接于第二杆件13的所述凹槽部131的底壁,限制第一杆件21的转动角度,对第一杆件21起到限位的作用。
进一步地,所述限位部221形成于所述活动部22远离所述第一杆件21且远离所述连接座12的一侧端部。活动部22远离所述第一杆件21且靠近所述连接座12的一侧端部形成有弧形部222,第一杆件21的活动部22相对相邻的两个所述第一防护组件10中的第一者的第一杆件13的转轴14转动时,所述弧形部222与第二杆件13的所述凹槽部131的底壁均不接触,以使得第一杆件21能够沿靠近旋翼组件91的方向转动至折叠状态。并且,第一杆件21转动至展开状态时,通过限位部221对第一杆件21起到限位作用。
在一些可选的实施例中,第一杆件21采用碳纤维管,具有一定的弹性形变能力。为了提高第二防护组件20与第一防护组件10的连接牢固度,所述限位部221的端面朝向远离所述第一杆件21的方向,相对所述第一杆件21的轴向呈倾斜设置。可选地,所述限位部221的端面相对所述第一杆件21的轴向的倾斜角度为1°至2°。
参见图16至图18所示,以第一防护组件10的第二连接部15和第二防护组件20的第一连接部23,采用上述第一种可拆卸连接方式为例。通过上述设置,当第一杆件21相对相邻两个第一防护组件10中的第一者转动至折叠状态时,受到限位部221的限位作用,第一杆件21不能与相邻两个第一防护组件10中的第二者的连接头17处于相齐平的位置,如图16所示。
由于第一杆件21具有一定的弹性形变能力,可以人为作用将第一杆件21弯折至越过相邻两个第一防护组件10中的第二者的连接头17,如图17和图18所示。再将第一杆件21的第一连接部23的卡槽231卡接于对应的第一杆件13的第二连接部15的销轴151内,如图5所示。此时第一杆件21受到自身的弹性复位力的作用并不能完全复位并仍保持一定的变形状态,这残留的一部分弹性变形所产生的力量可以对第一杆件13的第二连接部15的销轴151产生朝向旋翼组件91方向的拉紧力,可以使 卡槽231牢牢与销轴151结合,即使受到外部撞击力的作用,也不会轻易从销轴151中脱开,第二连接部15只能从内向外受力才能打开,从而提高第一防护组件10的第二连接部15和第二防护组件20的第一连接部23之间的连接牢固度。
综上所述,通过卡槽231与销轴151之间形成相互紧固的拉紧力,以及第一杆件21受自身的弹性复位力的作用对第一杆件13形成的拉紧力,以使得第二防护组件20和第一防护组件10从两个不同的方向相互拉紧,提高第一防护组件10与第二防护组件20之间的连接牢固度,保证无人机飞行状态时,防护装置具有足够的刚性和结构强度,提高飞行安全性。
参见图19至图21所示,在一些可选的实施例中,所述第二杆件13的第一端的连接头17上设有凹槽部131,所述转轴14设于所述凹槽部131内,所述凹槽部131的侧壁设有定位孔132。
第一杆件21的活动部22内穿设有定位件223,所述定位件223沿所述转轴14的轴向设置,所述定位件223的端部设有与所述定位孔132相适配的弹性定位部224,所述弹性定位部224可沿所述定位件223的轴向移动。可选地,弹性定位部224的端面为球面,定位孔132为球形孔,更便于弹性定位部224与定位孔132的内壁接触时发生相对移动。
当第一杆件21的活动部22相对相邻的两个所述第一防护组件10中的第一者的第二杆件13的转轴14转动,带动所述第一杆件21转动至折叠状态时,所述弹性定位部224移动至部分凸出于所述活动部22的表面,并卡接于第二杆件13的凹槽部131内的定位孔132内,对处于折叠状态的第一杆件21起到定位作用,防止第一杆件21处于折叠状态时的位置发生晃动和偏移,便于收纳并且能保证无人机处于收纳状态时的结构稳定性。
第二防护组件20从折叠状态转动至展开状态的过程中,第一杆件21的活动部22相对相邻的两个所述第一防护组件10中的第一者的第二杆件13的转轴14转动,带动所述第一杆件21转动至其他位置。在此转动过程中,定位件223的弹性定位部224与第二杆件13的定位孔132的内壁相接触,并随着转动而逐渐回缩。当弹性定位部224完全脱离定位孔132,弹性定位部224移动至与所述活动部22的表面齐平,并抵接于所述凹槽部131的侧壁。
为了达到更好的定位效果,所述凹槽部131的两侧侧壁设有位置对应的所述定位孔132,所述定位件223的两侧端部均设有所述弹性定位部224。通过上述设置,当第一杆件21处于折叠状态时,可以使定位件223与凹槽部131连接的更牢固,保证第二防护组件20的位置更稳固。
本申请实施例提供的无人机,通过配置所述防护装置,可以较好的保留多轴无人机的伞状折叠功能,在折叠后也能较好的适应多轴无人机形态,增强了收纳与便携 性。防护装置采用模块化的设计,可以适配于四轴、六轴、八轴以及变轴距无人机。防护装置可以对无人机的浆叶起到保护作用,此外防护装置的所有零件均可保证与无人机的机体有相对固定的位置关系,不存在会脱离机体的零件,降低了在无人机飞行途中因零件脱落造成飞行事故的几率。
