Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) flight accuracy testing technology, and in particular to a UAV flight accuracy testing device. Background Technology

[0002] A drone is an aircraft that performs flight missions via radio remote control or an autonomous flight control system. Relying on advanced sensors, remote sensing technology, and artificial intelligence algorithms, it possesses vertical takeoff and landing capabilities, autonomous navigation, and precise positioning. By carrying different sensors and equipment, drones can perform a variety of tasks and are widely used in fields such as aerial photography and mapping, agricultural plant protection, logistics transportation, and emergency rescue.

[0003] Unmanned aerial vehicle (UAV) flight accuracy testing is a crucial step in evaluating the deviation between a UAV's preset flight path and its actual flight trajectory. This is primarily achieved through multi-sensor fusion technology. Testing typically employs differential GPS, RTK, or PPK technologies, combined with radar or total station data acquisition to gather three-dimensional flight path data. The differences between the preset path and the actual flight trajectory are compared, and the horizontal and vertical error values ​​are calculated.

[0004] Existing testing devices, when mounted on drones, are mostly fixed to the drone's landing gear. However, some drones have strut-type landing gear, making them difficult to secure. Furthermore, the testing device's location below the drone makes it prone to interference between test signals and drone signals, leading to signal loss and other problems. To overcome these disadvantages, this invention provides a drone flight accuracy testing device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drone flight accuracy testing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a UAV flight accuracy testing device, comprising a connecting block, wherein rotating grooves are provided at both ends of the connecting block, a rotating block is rotatably connected to the rotating grooves, an adjusting frame is fixedly connected to one side of the rotating block, an adjusting block is slidably connected to the adjusting frame, a fixing component is provided on the adjusting frame, a fixing component is provided at the bottom of the adjusting block, a width adjusting component is provided on one side of the connecting block, first fixing holes are provided on both sides of the connecting block, a first fixing bolt is provided in the first fixing hole, a second fixing hole is provided on one side of the adjusting block, and a nut is threadedly connected to the first fixing bolt.

[0007] Furthermore, the fixing component includes a first arc-shaped clamping block fixedly connected to the bottom end of the adjusting block. The first arc-shaped clamping block has several first threaded holes on both sides, and a second fixing bolt is threadedly connected to the first threaded hole. A second arc-shaped clamping block is provided below the first arc-shaped clamping block. The second arc-shaped clamping block has several second threaded holes on both sides, and the second threaded holes and the second fixing bolt are threadedly connected.

[0008] Furthermore, the width adjustment component includes a threaded rod fixedly connected to one side of the connecting block. The threaded rod is provided with a handle, and both ends of the handle are provided with third threaded holes. The third threaded holes are threadedly connected to the threaded rod. Limiting components are provided on one side of the connecting block and on both sides of the threaded rod.

[0009] Furthermore, the limiting component includes a limiting rod that is fixedly connected to one side of the connecting block and to both sides of the threaded rod, and a limiting tube is slidably connected to the limiting rod.

[0010] Furthermore, the placement component includes a support frame fixedly connected to the top of the connecting block, and the support frame is provided with a placement box.

[0011] The beneficial effects of this utility model are:

[0012] In use, this invention uses a width adjustment component to adjust the distance between the two connecting frames according to the size of the drone, thus adapting to drones of different sizes. A fixing component secures the device to the drone's arm, making it suitable for most quadcopter and larger drones on the market. This avoids the problem of the device not being able to be fixed to the drone due to different drone support legs. The placement box for the test device is located above the drone, reducing the probability of signal interference generated during testing and by the drone itself. Attached Figure Description
