Description

Technical Field

[0001] The utility model relates to the technical field of test platforms, in particular to an unmanned aerial vehicle attitude test platform. Background Art

[0002] With the development of drone technology, more and more industries are beginning to use drones for related operations. Therefore, the testing of various parameters of drones has become very important. In order to improve the accuracy of drone test data, existing drone tests mostly use drone test platforms for testing.

[0003] In the prior art, a Chinese patent with publication number CN219565480U proposes a UAV test platform, in which the UAV is connected to a parking board. During the test flight, the UAV can freely adjust its flight attitude, and the rotating seat can freely rotate with the rotation of the UAV. The tension and compression sensors measure the data information of the forces in each direction, so that the lift data of the UAV in different flight attitudes can be measured. However, in actual application, the UAV is completely fixed to the parking board, which will result in the inability to measure the hovering attitude of the UAV during the UAV test, resulting in the problem that the UAV attitude test parameters are not perfect and accurate. Therefore, we disclose a UAV attitude test platform. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a UAV attitude test platform to solve the problem that the UAV and the parking board are completely fixed, resulting in inaccurate UAV attitude test parameters.

[0005] Based on the above-mentioned purpose, the utility model provides a UAV attitude test platform, including a base, the top end of the base is fixedly connected to a bracket, the middle part of the bracket is fixedly connected to a fixed plate, the middle part of the fixed plate is provided with two movable holes, the middle part of the fixed plate is movably connected to two connecting plates, the lower end of one connecting plate is fixedly connected to a first limiting column, the lower end of the other connecting plate is rotatably connected to a moving column through a connecting block, the first limiting column and the moving column respectively pass through the two moving holes, the bottom end of the moving column is fixedly connected to a push plate, the side of the push plate is fitted with a plurality of sensor assemblies, one end of the sensor assembly is fixedly connected to a fixed box, and a UAV body is arranged between the first limiting column and the moving column.
