Landing buffering device for unmanned aerial vehicle

Abstract

The invention discloses a landing buffering device for an unmanned aerial vehicle. The landing buffering device for the unmanned aerial vehicle comprises an unmanned aerial vehicle body, a frame and auxiliary buffering mechanisms, wherein the frame is fixedly arranged on the lower end surface of the unmanned aerial vehicle body; the auxiliary buffering mechanisms are arranged on one side of the frame; a carbon fiber pipe is fixedly arranged on the lower end surface of the frame; a first spring sleeves the carbon fiber pipe; an exhaust port is formed in one side of the bottom of an air cylinder; a mounting plate is fixedly arranged at the lower end of the air cylinder, and is connected with an undercarriage at the lower end through two crash boxes symmetrically arranged; the undercarriage is of an airbag structure; a cycle valve is fixedly arranged on one side of the undercarriage; three spring mounting seats are arranged on the undercarriage between the crash boxes; and second springs sleeve the spring mounting seats. The landing buffering device is simple and reasonable in structural design; and crash energy is consumed step by step when the unmanned aerial vehicle lands through a multi-stage damping component, the damping process is more stable, the buffering effect is good, the resilience is slow, the secondary damage is avoided, and the condition that the unmanned aerial vehicle sinks into rivers and lakes at failure can be avoided.

Description

technical field

[0001] The invention relates to the technical field of drones, in particular to a landing buffer device for drones. Background technique

[0002] At present, UAVs have been widely used in aerial remote sensing, meteorological research and agricultural aerial broadcasting, especially in war, they have special advantages and can be widely used in aerial reconnaissance, surveillance, communication, anti-submarine and electronic jamming, etc. However, in When using a UAV in the wild, due to the complex terrain, when the UAV lands on a complex ground, it is easy to land unstable and cause damage. Most of the existing UAVs do not have shock absorbers, and only a few use springs to absorb shocks. This will not only impact some important parts when landing, but also if the UAV lands too fast or falls out of control, it is easy to damage the landing gear or even the body, and the existing spring method will bounce violently after landing. Large, it is easy to cause s...
