Modular assembled four-axis plant protection unmanned aerial vehicle (UAV)

Abstract

The invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular discloses a modular assembled four-axis plant protection UAV, comprising a chassis and a power control center, wherein the power control center is fixed in the center of the chassis by means of an installation clamping groove; four corners of the chassis are respectively connected with a cantilever, ends of the cantilevers are respectively connected with a motor, and output shafts of the motors are respectively connected with a propeller; the chassis comprises an X-axis direction module and a Y-axis direction module; the X-axis direction module and the Y-axis direction module respectively have a cavity structure which is provided with two openings in two ends and has hollow interior; the X-axis direction module is connected with the Y-axis direction module by means of an inserting mechanism; four rotary connecting pieces are respectively installed at the four corners of the Y-axis direction module; the cantilevers are connected with the rotary connecting pieces by means of the inserting mechanism. The modular assembled four-axis plant protection UAV can enable the chassis, the cantilevers and the like of the UAV to be integrated and modularized while guaranteeing the structural safety, the later assembly and maintenance of the UAV can be facilitated, and the service life of the UAV is prolonged.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a modularly assembled four-axis plant protection unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", or "UAV" in English, is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. [0003] Drones are often better suited for missions that are too "dumb, dirty or dangerous" than manned aircraft. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, drones + industry applications are the real rigid needs of drones; currently, they are used in aerial photography, agriculture, plant protection, micro selfies, express delive...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is: for the existing structures such as the skeleton of the UAV are integrally formed by injection molding, it is necessary to realize the connection of the circuit at the same time during the process of structural assembly, and it is also necessary to replace the electrical components and structural parts later. In order to re-find the corresponding lines and bring inconvenience to assembly and maintenance, a modular assembly four-axis plant protection drone is provided. The frame and cantilever are all modular structures, and the lines are encapsulated in each pipe fitting. Internally, the two ends of the pipe fittings are equipped with a plug-in structure, and the connection of the line is completed after assembly. If the line is broken, the entire pipe fitting can be replaced directly. Modularization facilitates the assembly and maintenance of the UAV in the later stage and improves the service life of the UAV
