Four-rotor unmanned aerial vehicle lift test device

Abstract

A four-rotor unmanned aerial vehicle lift test device includes a load test bench, a tension transducer, a connecting rod, the arm of the unmanned aerial vehicle is fixedly positioned above the load test bench, the connecting rod passes through the side wall of the load test bench and is perpendicular to the load test bench base, the tension sensor is fixed to the base of the load test bench, The upper end of the connecting rod is perpendicular to the arm of the UAV through magic sticker, the lower end of the connecting rod is connected with a tension sensor, the other end of the tension sensoris connected with a display, the tension force is read out and analyzed, the overall balance of the UAV and the running effect of a single motor are obtained, and the overall performance of the UAV can be judged more easily; The device can be installed from bottom to top, which is convenient to install, simple in structure, easy to process parts and convenient to purchase.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a lift test device for a quadrotor unmanned aerial vehicle. Background technique [0002] According to the number of rotors, multi-rotor drones can be divided into four-rotor, six-rotor, eight-rotor and other types; [0003] Multi-rotor UAVs are used in education, scientific research, aerial photography, military, police safety, transportation, agriculture and other fields. Multi-rotor UAVs are widely used. An important part, the traditional multi-rotor UAV lift test device uses a lever to test the lift, which mainly has the following disadvantages: 1. It is complicated, and the installation and connection of parts is troublesome; 2. It has errors, and the balance lever Unable to achieve zero adjustment; 3. It is unstable, and the overall force direction of the UAV cannot be vertically upward; 4. The structure is complex, and it is difficult to process or purchase some pa...
