Six-rod tensioning integral frame and anti-impact unmanned aerial vehicle

Abstract

According to the six-rod tensioning integral frame and the anti-impact unmanned aerial vehicle, the six rigid pressing rods and the twenty-four elastic cables are included, the four elastic cables are led out of the two end points of each rigid pressing rod correspondingly, the four elastic cables of each end point are connected with the four end points closest to the end point correspondingly, the six rigid pressing rods are averagely divided into three groups, and the six rigid pressing rods are divided into three groups; in the spatial position, any two sets of rigid pressing rods in the three sets of rigid pressing rods are perpendicular to each other, and the two rigid pressing rods in each set are parallel to each other. The structure is light in weight and can provide high-strength impact resistance, the influence on the cruising ability of the unmanned aerial vehicle is reduced while the mechanical structure of the unmanned aerial vehicle is protected, and the unmanned aerial vehicle can fly in the air, can orderly and controllably roll on the ground and can take off again after falling off.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a six-bar tensioned integral frame and an impact-resistant unmanned aerial vehicle. Background technique [0002] For ordinary drones, it is very challenging to fly in a complex environment where obstacles are difficult to detect and avoid. Obstacles in the environment are a great threat to the safety and integrity of the UAV's mechanical structure. A little carelessness will damage the UAV's rotor or arm, causing the UAV to crash. [0003] After extensive investigation, it is found that there are two main buffer structures for UAVs. One is to install an elastic, spherical buffer structure outside the UAV, and use the spherical structure to buffer external forces to protect the UAV. , but this drone cannot take off again after being hit and landed. The other is to install a structure similar to a squirrel cage on the outside of the UAV, so that the UAV relies on its ...

AI Technical Summary

Problems solved by technology

[0003] After extensive research, it is found that there are currently two main buffer structures for UAVs. One is to install an elastic, spherical buffer structure outside the UAV, and use the spherical structure to buffer external forces to protect the UAV. , but this drone cannot take off again after being hit and landed

The other is to install a structure similar to a squirrel cage on the outside of the UAV, so that the UAV relies on its own gravity to maintain the level of the wings. The buffering effect of the force is limited, and it cannot provide a stable landing ground for the UAV. This UAV can also only fly but cannot perform controllable rolling on the ground
