AI Technical Summary

Technical Problem

Existing drones lack obstacle avoidance capabilities, especially in high-risk operating environments where their passive buffering capabilities are insufficient, failing to effectively protect drones during safe operation.

Method used

A drone obstacle avoidance and buffer protection mechanism has been designed, including a cover assembly and a buffer assembly. The cover assembly is covered by first and second wrapping bodies, and the buffer assembly is composed of a buffer layer and first and second interlayers. The interlayer cavity design enhances the buffering capacity and is detachably installed at the end of the drone's support legs.

Benefits of technology

It enhances the drone's passive buffering capability in high-risk environments, avoids deformation interference when subjected to external impacts, and improves the drone's safety and stability.

Abstract

The utility model discloses an unmanned aerial vehicle obstacle avoidance buffer protection mechanism which comprises a cover body assembly and a buffer assembly, and the buffer assembly is detachably embedded in the cover body assembly. The cover body assembly comprises a cover body, a first wrapping body and a second wrapping body, the first wrapping body and the second wrapping body are arranged outside the cover body, the first wrapping body and the second wrapping body wrap part of the cover body respectively, the first wrapping body and the second wrapping body are fixedly connected with the cover body respectively, and a gap is formed between the first wrapping body and the second wrapping body; the buffer assembly comprises a buffer layer, a first interlayer and a second interlayer, the buffer layer is arranged in the cover body, and the buffer layer is provided with a buffer layer inner cavity. The obstacle avoidance buffer protection mechanism for the unmanned aerial vehicle has the advantages that the obstacle avoidance buffer protection mechanism can be additionally arranged at the tail end of a supporting leg of an existing unmanned aerial vehicle according to needs, and the passive buffer capacity of the existing unmanned aerial vehicle in a high-risk operation environment is enhanced.
