Telescopic folding arm assembly, control device and hovercar

The invention discloses a telescopic folding arm assembly, a control device and a hovercar. One end of the telescopic folding arm assembly is connected with a fuselage of the hovercar, and the other end is connected with a rotor wing assembly of the aircraft; the vehicle arm assembly comprises a vehicle arm body and a vehicle arm telescopic mechanism. And the arm telescopic mechanism controls the arm body to do linear telescopic motion, so that the length change of the arm body is realized. By the adoption of the flying car, the size of the flying car can be reduced in the mode that the telescopic folding arms are arranged, the size and weight of the whole car are reduced, and the load capacity is improved. And balance between increasing the length of the blades, improving the lift force of the hovercar and keeping or reducing the volume and the weight of the whole hovercar is facilitated. 本发明公开了一种可伸缩折叠机臂组件、控制装置及飞行汽车。所述可伸缩折叠机臂组件，一端连接飞行汽车的机身，另一端连接飞行器的旋翼组件；所述机臂组件包括机臂本体和机臂伸缩机构；所述机臂伸缩机构，控制所述机臂本体进行直线伸缩运动，实现机臂本体的长短
