Automatic resetting platform for unmanned aerial vehicle

Abstract

The invention discloses an unmanned aerial vehicle automatic reset platform and is applied to an unmanned aerial vehicle with four universal wheels at the bottom. The platform comprises a supporting table, wherein a downwards-sunken reset groove is formed in the middle of the supporting table, positioning parts are arranged at four corners of a bottom face of the reset groove respectively, a guide face is connected between every two adjacent positioning parts, and the middle of each guide face is higher than two ends of the guide face; a side face of the reset groove is a gradual change face connected with the outer side edge of the guide face. The automatic resetting platform for the unmanned aerial vehicle has advantages of simple structure, small occupied space, low cost, capability of realizing automatic resetting of the unmanned aerial vehicle, convenience in taking off of the unmanned aerial vehicle and the like.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to an automatic reset platform for drones. Background technique [0002] With the rise of drones, unmanned airports with drones have developed a lot. The UAV takes off from the airport platform, returns to the airport after the mission is completed, and lands on the platform to recharge or replace the battery. To do this, the UAV must be landed precisely in the position before take-off and departure. The error of the landing of the existing drones is about ±10 centimeters. In order to eliminate errors, precise reset. Now generally all adopt " well " shaped manipulator resetter. That is, after the UAV lands, the left, right and front and rear mechanical arms move to the middle, pushing the UAV to the middle position when it takes off, so as to achieve precise reset. And use the mechanical arm to press the drone's machine feet, fix the drone to prevent the wind and other disturban...

AI Technical Summary

Problems solved by technology

[0003] 1. The structure of setting up the manipulator is complicated and the cost is high;

[0004] 2. The manipulator needs to occupy a large installation space, which increases the occupied space of the entire platform;

[0005] 3. It is troublesome to reset by manipulator, it needs manual monitoring, and it is difficult to realize automatic reset;

[0006] 4. After reset, you need to wait for the mechanical arm to be released before taking off, which is inconvenient to take off

[0007] Moreover, after the UAV is reset, the propeller of the UAV is easy to rotate under the action of wind, and there is a lack of a limit device for the propeller. In this way, it is easy to cause the UAV to shake, and even the rotating propeller will damage other parts. object
