Description

飞行器防虚位折叠装置
技术领域
本发明涉及种飞行器技术领域，尤其是一种飞行器防虚位折叠装置。
背景技术
飞行器机臂折叠结构有很多种：1、旋钮卡扣结构，2、按压反扣结构，这两种折叠结构或多或少都会出现虚位，很大程度上降低了电机的工作效率，使飞行器的载荷与续航时间减小，使产品的质感也大打折扣。
发明内容
本发明的目的是解决现有技术的不足，提供一种飞行器防虚位折叠装置。
本发明的一种技术方案：
一种飞行器防虚位折叠装置，包括两平行的固定板，固定于两固定板之间的固定杆，限位杆，弹簧以及旋转臂；固定板沿其长度方向设有滑槽，滑槽内设有沿滑槽滑动的滑杆，限位杆的一端穿过固定杆且与固定杆滑动连接，另一端与滑杆固定连接，压缩弹簧环套于限位杆外且夹于固定杆与滑杆之间；旋转臂的一端与机臂固定连接，另一端延伸有两平行的旋转板，旋转板与固定板旋转连接，旋转板远离机臂的一侧设有与滑杆抵接的弧形缺口；当滑杆移向固定杆时，滑杆与弧形缺口脱离，此时旋转臂沿转轴旋转，当滑杆移向弧形缺口并与弧形缺口接触时，弧形缺口沿滑杆滑动。
一种优选方案是滑杆与弧形缺口接触的面为平面。
一种优选方案是限位杆为螺丝，螺丝的两外端分别设有限位螺母。
一种优选方案是固定板和旋转臂的表面分别设有加强筋。
一种优选方案是弧形缺口位于旋转板的左上角，弧形缺口与旋转板的上端面之间形成一止位部，滑杆于弧形缺口与止位部之间滑动。
综合上述技术方案，本发明的有益效果：滑杆在外力作用下往固定杆方向滑动时，滑杆与弧形缺口脱离，旋转臂绕转轴旋转，此时，旋转臂处于折叠状态；当外力去除时，滑杆在弹簧的作用下往弧形缺口方向移动，滑杆与弧形缺口的弧面接触，此时，滑杆与弧形缺口的弧面之间的间隙越来越小，直至间隙消失，因此，可以实现防虚位。
上述说明仅是本发明技术方案的概述，为了能够更清楚了解本发明的技术手段，可依照说明书的内容予以实施，并且为了让本发明的上述内容和其他目的、特征和优点能够更明显易懂，以下特举实例，并配合附图，详细说明如下。
附图说明
图1是本发明中旋转臂展开时的立体图；
图2是本发明中旋转臂折叠时的立体图；
图3是本发明的爆炸图。
具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面结合附图对本发明做进一步描述。
如图1至图3所示，一种飞行器防虚位折叠装置，包括两平行的固定板101，固定于两固定板101之间的固定杆102，限位杆105，弹簧103以及旋转臂201；固定板101沿其长度方向设有滑槽107，滑槽107内设有沿滑槽107滑动的滑杆104，限位杆105的一端穿过固定杆102且与固定杆102滑动连接，另一端与滑杆104固定连接，压缩弹簧103环套于限位杆105外且夹于固定杆102与滑杆104之间；旋转臂201的一端与机臂固定连接，另一端延伸有两平行的旋转板202，旋转板202与固定板101旋转连接，旋转板202远离机臂的一侧设有与滑杆104抵接的弧形缺口203；当滑杆104移向固定杆102时，滑杆104与弧形缺口203脱离，此时旋转臂201沿转轴106旋转，当滑杆104移向弧形缺口203并与弧形缺口203接触时，弧形缺口203沿滑杆104滑动。
具体的，如图1至图3所示，两旋转板202夹于两两固定板101之间，且通过转轴106形成旋转连接，两旋转板202绕转轴106自由旋转。弧形缺口203位于旋转板202的左上角，弧形缺口203与旋转板202的上端面之间形成一止位部204，滑杆104于弧形缺口203与止位部204之间滑动。本实施例中，滑杆104与弧形缺口203接触的面为平面，滑杆104在外力作用下往固定杆102方向滑动时，滑杆104与弧形缺口203脱离，旋转臂201绕转轴106旋转，此时，旋转臂201处于折叠状态；当外力去除时，滑杆104在弹簧103的作用下往弧形缺口203方向移动，滑杆104的平面与弧形缺口203的弧面接触，此时，滑杆104的平面与弧形缺口203的弧面之间的间隙越来越小，直至间隙消失，因此，可以实现防虚位。
如图1至图3所示，限位杆105为杯头内六角螺丝，杯头内六角螺丝的另一端设有防松螺母108，防松螺母108用于防止滑杆104脱离限位杆105，固定杆102和滑杆104限制于杯头内六角螺丝与防松螺母108之间，防止固定杆102或滑杆104与限位杆105脱离。为了减少飞行器防虚位折叠装置的重量同时增加其强度，在固定板101和旋转臂201的表面分别设有加强筋。
以上是本发明的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和修饰，这些改进和修饰也视为本发明的保护范围。
