Abstract

The invention discloses an unmanned aerial vehicle based on a six-pressure-rod integral tension structure. The unmanned aerial vehicle body has a stable space structure composed of a set of discontinuous pressed components and a set of continuous pressed components which are connected with each other; the unmanned aerial vehicle has a unique foldable feature, light weight and beautiful structure appearance; vehicle body and vehicle arms of the multi-rotor unmanned aerial vehicle can form an integral tension structure and form an unmanned aerial vehicle with a foldable structure; in the unmanned aerial vehicle based on the integral tension structure, rotors are arranged at the tail ends of the pressure rods; a control system of the unmanned aerial vehicle is installed on a central positionof the vehicle body; four retractable retraction components are arranged in the unmanned aerial vehicle and are capable of changing rotor driving positions and having compound motions, such as pitching, yawing and torsion; the unmanned aerial vehicle is capable of continuously deforming through an elastic cable; different deformations are corresponding to various postures, in order to adapt to different working environments (such as taking off and landing); the unmanned aerial vehicle has an ultrahigh engineering application value.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to an unmanned aerial vehicle based on a six-bar overall tension structure. Background technique [0002] UAV refers to an unmanned aircraft controlled by wireless remote control equipment and its own control device. This equipment integrates technologies such as mechatronics, computer communication and navigation control, and can perform real-time control of motion trajectory in complex environments. At present, UAVs have been widely used in fields such as aerial photography, power inspection, environmental monitoring, forest fire prevention, disaster inspection, anti-terrorism lifesaving and military reconnaissance, etc. maintenance costs. However, in the process of operation, the UAV has the problems of short operation time, heavy body weight, inability to fold (inconvenient to carry), and difficulty in taking off and landing in a complex environment...
