The invention relates to a divisional application of a Chinese invention patent application 202210654138.8, and discloses a controllable folding variable pitch device which comprises a propeller seat, a propeller, a blade transmission rod, a rotary transmission ring, a translation transmission ring, a rack, a brake disc, a brake protrusion, a worm and a worm wheel. The propeller seat, the rotating transmission ring, the translation transmission ring and the retracting and releasing driver are all distributed and installed on the power base pipe, the brake disc and the brake protrusion form a propeller retracting and braking system, and the worm and the worm wheel form the retracting and releasing driver. According to the controllable folding variable-pitch device, only controllable unfolding and folding are conducted on the propellers, switching of the propellers is achieved, compared with a general scheme that the whole power unit is folded, the complexity and the device weight are greatly reduced, and the problems that an existing vertical take-off and landing fixed wing is short in endurance, small in load, large in dead load and large in wind resistance are solved.

    本申请是中国发明专利申请202210654138.8的分案申请,本发明公开了一种可控折叠变桨装置,它包括桨座,螺旋桨,桨叶传动杆,旋转传动环,平移传动环,齿条,刹车盘,刹车突起,蜗杆,蜗轮;所述桨座,旋转传动环,平移传动环,收放驱动器,均分布安装在动力基座管上,所述刹车盘、刹车突起组成了收桨刹车系统,所述蜗杆、蜗轮组成了收放驱动器。本发明提供的一种可控折叠变桨装置,仅对螺旋桨进行可控展开和收起,实现螺旋桨的切换,相比一般将整个动力单元都收起方案,大幅度减小了复杂程度以及装置重量,解决了现有垂直起降固定翼续航短、载重小、死重大、风阻大的问题。
