Unmanned aerial vehicle intelligent parachute device with parachute opening and propeller stopping tightly coupled

Abstract

The invention belongs to the technical field of unmanned aerial vehicle equipment, and particularly relates to an unmanned aerial vehicle intelligent parachute device with parachute opening and parachute stopping tightly coupled; compared with the prior art, propeller sudden stop and parachute opening control of the unmanned aerial vehicle intelligent parachute device (1) with parachute opening and parachute stopping tightly coupled are integrated; two actions of parachute opening and propeller emergency stop are strongly coupled, so that the parachute opening and propeller emergency stop arein a causal relationship, the working principle that the parachute of the unmanned aerial vehicle needs to be stopped when opened and needs to be opened when stopped is completely met, and the stability of the parachute safety device is improved; (2) airborne equipment power supply control is realized, and an airborne equipment power supply can be synchronously switched off when the parachute is ejected, so that the airborne equipment is prevented from being damaged when working in an unstable environment in the parachuting process, the emergency stop capability of an out-of-control propelleris further enhanced, and the working stability of a parachute system is improved; and the device is also used for preventing a high-speed rotating propeller from hurting human bodies and properties inemergency.

Description

technical field [0001] The patent of the invention belongs to the technical field of unmanned aerial vehicle equipment, and specifically relates to an intelligent parachute device for unmanned aerial vehicles that is tightly coupled with parachute opening and propeller stop. Background technique [0002] At present, during the deployment process of the UAV parachute, the parachute and the parachute rope are easily involved by the out-of-control propeller, so that the parachute cannot be fully deployed, which seriously affects the stability of the UAV parachute during and after the parachute is opened. In addition, the uncontrolled UAV will continue to output power from the propeller after the parachute is deployed, which will cause the UAV to roll and drift irregularly after the parachute is opened, which will lead to the failure of the parachute system and a secondary fall. In addition, the out-of-control propeller rotating at high speed will cause very serious injuries to ...

AI Technical Summary

Problems solved by technology

[0002] At present, during the deployment of the parachute of the UAV, the parachute and the parachute rope are easily involved by the out-of-control propeller, so that the parachute cannot be fully deployed, which seriously affects the stability of the UAV parachute during and after the parachute is opened.

In addition, if the uncontrolled drone continues to output power from the propeller after the parachute is deployed, the drone will roll and drift irregularly after the parachute is opened, which will lead to the failure of the parachute system and a secondary fall

In addition, the out-of-control propeller rotating at high speed will cause very serious injury to people and objects

On the other hand, the UAV airborne equipment is in an unstable working environment during the UAV parachute, and it is prone to fire and failure when it continues to work
