Unmanned aerial vehicle protection mechanism for preventing crash in the case of signal loss

Abstract

The invention relates to the technical field of unmanned aerial vehicles, and discloses an unmanned aerial vehicle protection mechanism for preventing crash in the case of signal loss. The unmanned aerial vehicle protection mechanism comprises a unmanned aerial vehicle body, wherein a protection device is fixedly installed in the middle part of the bottom end of an inner cavity of the unmanned aerial vehicle body; the protection device is divided into a triggering device and an opening mechanism; the triggering device is fixedly installed in the middle part of the inner cavity of the unmannedaerial vehicle body; and one end of the interior of the triggering device is communicated with an inner cavity of the opening mechanism, and a folding umbrella-shaped skeleton is fixedly installed atthe bottom end of the opening mechanism. According to the unmanned aerial vehicle protection mechanism for preventing crash in the case of signal loss, by arranging the protection device, when the unmanned aerial vehicle falls, the protection device can be extended order by order and the folding umbrella-shaped skeleton can be finally opened; no matter in what kind of posture the unmanned aerial vehicle falls to the ground, effective protection measures can be formed for the unmanned aerial vehicle; and compared with an existing unmanned aerial vehicle protection device, the protection effectis better and the protection range is more comprehensive, and therefore, a situation that no damage is generated when the unmanned aerial vehicle falls accidentally is ensured.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a drone protection mechanism for preventing crashes due to signal loss. Background technique [0002] UAVs (such as figure 1 Shown) is a flying device controlled by radio remote control equipment and self-contained program, which is mainly used in technical fields such as aerial photography, plant protection, observation and monitoring, surveying and mapping, and has achieved good results. [0003] However, due to the instability in the radio transmission process and the influence of various factors in the external environment, during the control process of the UAV, it often falls out of control and is damaged due to the loss of the signal. Therefore, in order to prevent unmanned At present, the crash of the drone is mainly to set the cushion pad at the bottom of its landing gear to reduce the impact force of the drone when it falls. At the same time, it is equipped with parachut...

AI Technical Summary

Problems solved by technology

[0006] The invention provides a UAV protection mechanism for signal loss and crash prevention, which has the advantages of good protection effect, relatively comprehensive protection range, high stability and reliability, and can be used repeatedly, solving the problem of existing protection devices It can only play a protective role when the UAV falls vertically. When it lands obliquely, it will also cause damage to the fuselage or wings of the UAV, and the protection effect is poor.
