Unmanned aerial vehicle and buffering device used for landing of unmanned aerial vehicle

Abstract

The invention relates to the field of unmanned aerial vehicles and discloses a buffering device used for landing of an unmanned aerial vehicle and the unmanned aerial vehicle provided with the buffering device. The buffering device used for landing of the unmanned aerial vehicle comprises an upper shell used for being fixedly connected with the bottom of an unmanned aerial vehicle body, a lower shell fixed to the lower portion of the upper shell, a power component and a buffering component which are fixedly arranged relative to the lower shell. When the unmanned aerial vehicle lands, the powercomponent depends on upstream airflow with the motion direction opposite to that of the unmanned aerial vehicle to supply power so as to drive the buffering component to enter in a buffering state. When the unmanned aerial vehicle lands, the upstream airflow can supply power to the power component, the power component can drive the buffering component to enter in the buffering state through the power, so that impact on the vehicle body in the landing process is reduced, and the vehicle body is protected.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a device located at the bottom of the unmanned aerial vehicle and capable of buffering and protecting when landing. Background technique [0002] UAV is an unmanned aircraft controlled by radio remote control equipment and its own program control device. Civilian UAV has important applications in aerial photography, agriculture, plant protection, disaster relief and other fields. [0003] A multi-rotor UAV is a special unmanned helicopter with three or more rotor shafts. It drives the rotor through the rotation of the motor on each axis, thereby generating thrust. By changing the relative speed between different rotors, the magnitude of the single-axis propulsion can be changed, thereby controlling the trajectory of the aircraft. [0004] When the multi-rotor UAV lands and touches the ground, it is necessary to perform shock absorption to protect the fuselage. At present,...

AI Technical Summary

Problems solved by technology

[0004] When the multi-rotor UAV lands and touches the ground, it is necessary to perform shock absorption to protect the fuselage. At present, there are few such shock-absorbing and buffering devices, and some existing shock-absorbing and buffering devices are not ideal. Therefore, it is necessary to design a A buffer device that is more reasonable and has better shock absorption and buffering effects
