The invention relates to a variable-pitch rotor wing folding device which comprises a paddle assembly, a main shaft assembly, a lifting assembly and a folding assembly, the paddle assembly is fixedly installed at the upper end of the main shaft assembly, the main shaft assembly comprises a main shaft and a driving part, and the driving part is arranged on the main shaft; the lifting assembly is installed on the main shaft, the lifting assembly is in transmission connection with a folding assembly, and a paddle assembly is installed on the folding assembly; the lifting assembly drives the folding assembly to be folded or unfolded, and an elastic reset piece abutting against the lifting assembly is fixedly installed at the top end of the lifting assembly. The folding assembly and the lifting assembly are arranged, when the rotor wings are folded, the swash plate immovable ring moves upwards to drive the lifting assembly to move upwards, the lifting assembly and the folding assembly are in transmission fit, the folding assembly rotates downwards while the lifting assembly moves upwards, and the paddle assembly installed on the folding assembly is folded along with the folding assembly; the air resistance of the aircraft is reduced, the energy utilization rate is improved, and the endurance time is prolonged.
本发明涉及一种可变桨距的旋翼折叠装置,包括桨叶组件、主轴组件、升降组件和折叠组件,主轴组件的上端部固定安装有桨叶组件,主轴组件包括主轴和驱动部,驱动部设于主轴上;升降组件安装在主轴上,升降组件传动连接有折叠组件,折叠组件上安装有桨叶组件;升降组件驱动折叠组件折叠或展开,升降组件的顶端部固定安装有与升降组件相抵顶的弹性复位件。本发明设置有折叠组件和升降组件,在旋翼进行折叠时,倾斜盘不动环向上移动,带动升降组件向上移动,升降组件和折叠组件通过传动配合,在升降组件上移的同时折叠组件向下旋转,安装在折叠组件上的桨叶组件随之折叠起来,减小飞行器的空气阻力,提升能量利用率,延长续航时间。
