Technical Field

[0001] The utility model relates to the technical field of coaxial twin-rotors, in particular to a movable platform for coaxial twin-rotor testing. Background Art

[0002] Coaxial twin-rotor unmanned helicopters lack tails, reducing their structural complexity. However, during takeoff and landing, the airflow can easily pick up debris, causing foreign object impacts on the rotors. The rotors provide lift for coaxial twin-rotor drones, but significant damage to the rotors can compromise their flight performance.

The mounting block 5 is positioned and mounted on the first optical platform 2, and test equipment is mounted through the mounting block 5, so that the twin-rotor assembly 4 and the test equipment are precisely positioned horizontally and vertically, thereby improving the accuracy of the test. The drive assembly 6 drives the second optical platform 3 to move forward and backward relative to the first optical platform 2, so that the relative position of the twin-rotor assembly 4 and the test equipment can be accurately adjusted at any time, making the test more flexible and convenient.

[0032] As a preferred embodiment of the present invention, it may also have the following additional technical features:

The second optical platform 3 is fixed to the screw slider 603. The drive motor 601 drives the screw 602 to rotate, thereby driving the screw slider 603 and the second optical platform 3 to move back and forth, thereby adjusting the relative position of the first optical platform 2 and the second optical platform 3.

[0034] In this embodiment, a front side plate 102 is fixedly provided at the front end of the base plate 1 , and the driving motor 601 is fixed on the front side plate 102 . The driving motor 601 is fixed by the front side plate 102 .

[0035] In this embodiment, a rear side plate 103 is fixedly provided at the rear end of the base plate 1 , and the screw rod 602 abuts against the rear side plate 103 .

[0036] In this embodiment, the driving motor 601 is a servo motor, which can accurately adjust the stroke of the screw slider 603.

[0037] In this embodiment, the dual rotor assembly 4 and the mounting block 5 are both mounted in conjunction with the mounting hole 7 via a bolt connection structure. The dual rotor assembly 4 and the mounting block 5 are mounted via a bolt connection structure for easy assembly and disassembly.
