Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as any limitation to the present invention.

[0025] Such as figure 1 and 2 Shown: the propeller 1 in the figure is an existing product, and the letters a1 and a2 of all the nodes in the figure are the connection points of the rigid pressure bar 2 (thick black line) and the elastic cable 3 (thin line), that is, the pressure bar and the For the connection end 4 of the cable, these letters are used as design parameters in the present invention, such as the length of a1a2, and those skilled in the art can take values ​​by themselves in actual production.

[0026] For the unmanned aerial vehicle with the overall structure of four compression rods, the length of four rigid compression rods 4 is 300mm, the section radius is 10mm, and the length of eight horizontal elastic flexible cables 3 is 150mm, and the section radius is 2.5mm. The length of the s...

Abstract

The invention discloses a multi-rotor unmanned aerial vehicle based on a four-press-rod integral tensioning structure. The multi-rotor unmanned aerial vehicle based on the four-press-rod integral tensioning structure is an unmanned aerial vehicle with the four-press-rod integral tensioning structure as an unmanned aerial vehicle main body. An unmanned aerial vehicle body is formed in such a way that a series of discontinuous compression units and a series of continuous tension units act upon each other. In the unmanned aerial vehicle body, the compression units are press rods, the tension units are inhaul cables, and mutual acting points of the units and the units are nodes; and the press rods are in contact with each other, the inhaul cables form a continuous tension network, and therefore, a space shape with a stable structure is formed. According to the multi-rotor unmanned aerial vehicle based on the four-press-rod integral tensioning structure, combination between a rigid member and a flexible member is realized; and the multi-rotor unmanned aerial vehicle based on the four-press-rod integral tensioning structure has the advantages of deformable performance, easy folding, goodground environment adaption and the like. Meanwhile, the multi-rotor unmanned aerial vehicle based on the four-press-rod integral tensioning structure has the advantages of simpler structure, easierdriving and less desired driving energy.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a multi-rotor unmanned aerial vehicle based on a four-bar integral 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, when drones are operating, they will face the security threats of complex obstacles such as rugged terrain, mountains, buildings, trees and power lines. Based on this, the present invention pr...
