Unmanned aerial vehicle with buffering function and convenience in safe landing

Abstract

The invention relates to an unmanned aerial vehicle with a buffering function and convenience in safe landing. The unmanned aerial vehicle comprises a main body and four flight mechanisms, and each flight mechanism comprises a flat panel, a rotor wing and a supporting assembly; each supporting assembly comprises a fixed block, a movable block, a slide block, a slideway, a spring, a support leg, asupport rod, a limiting frame, an air cylinder, an air pipe, a sealing plate and an air rod. When the unmanned aerial vehicle with the buffering function and convenience in safe landing lands, the springs in the supporting assemblies apply tension force to the movable blocks, and thus the opening speed of the support legs and the descending speed of the main body are reduced; meanwhile, an airbagis inflated and utilized for isolating and protecting the main body, the situation that the main body is in contact with the ground, collides with the ground and gets damaged is avoided, thus safe landing of the unmanned aerial vehicle is achieved, and the practicability of the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle with a buffer function and convenient for safe landing. Background technique [0002] Unmanned aerial vehicle, unmanned aerial vehicle (UAV) for short, is a new concept weapon equipment in rapid development, which has the advantages of flexible maneuvering, quick response, unmanned flight, and low operation requirements. UAVs equipped with multiple types of sensors can realize real-time image transmission and detection of high-risk areas, which is a powerful supplement to satellite remote sensing and traditional aerial remote sensing. At present, the scope of use of UAVs has been expanded to the three major fields of military, scientific research, and civilian use, specifically in power, communications, meteorology, agriculture, ocean, exploration, photography, disaster prevention and reduction, crop production estimation, anti-drug anti-smugglin...

AI Technical Summary

Problems solved by technology

[0003] However, the structure of the existing UAV is simple and fixed, especially the legs under the UAV. When the UAV falls from a high place after performing the mission, the UAV’s descending speed gradually increases. The impulse of the drone is relatively large. After the drone has landed many times, the feet are easily damaged, causing the main body of the drone to contact and collide with the ground, resulting in damage to the internal precision electronic instruments, and the structure of the feet of the drone is fixed. When landing, Vibration is prone to occur, causing the electronic equipment inside the drone to vibrate, deviating from the original position, affecting the normal use of the drone, thereby reducing the practicability of the existing drone
