Detailed Implementation

[0012] The invention will now be further described with reference to the accompanying drawings. Example

[0013] like Figures 1 to 8 As shown, this embodiment of a drone for testing microwave absorbing materials includes a drone 1 and a test microwave absorbing material patch 2. The drone 1 has a fuselage, and the test microwave absorbing material patch 2 is used for testing and is mounted on the upper surface of the fuselage. In this application, the drone used is the commercially available model E88, brand MSRC, as the drone for testing the microwave absorbing material patch. Microwave absorbing material is a functional composite material that primarily absorbs electromagnetic waves, eliminating the back-and-forth reflection of electromagnetic waves within a shielding cavity, reducing interference from clutter on the device itself, and effectively preventing electromagnetic radiation from harassing and harming surrounding equipment and personnel. It is an advanced means of eliminating electromagnetic pollution. The thickness of the test microwave absorbing material patch includes: 0.08mm, 0.1mm, 0.2mm, and 0.3mm. Because the microwave absorbing material patch has an adhesive backing layer, when testing the performance of the microwave absorbing material patch using the structure of this application, the adhesive backing layer can be left intact, and the entire microwave absorbing material patch can be firmly clamped to the upper surface of the drone fuselage. This facilitates the replacement of test microwave absorbing material patches with different performance characteristics for drone performance testing.

[0014] The existing microwave absorbing materials used in UAV 1 include microwave absorbing patches and microwave absorbing coatings. Using microwave absorbing patches requires adhesive to be applied to the surface of UAV 1, which makes replacement inconvenient due to the adhesive layer 211. Using microwave absorbing coatings is unsuitable for testing microwave absorbing materials, as it is inconvenient to test the performance of different materials and makes it difficult to change to different ones. Therefore, it is not suitable for using UAV 1 to test microwave absorbing materials with different performance characteristics. This application improves upon this inconvenient structure by providing a movable clamping mechanism 3 on the surface of UAV 1 for testing microwave absorbing material patches 2. This movable clamping mechanism 3 can flexibly test different microwave absorbing material patches by using connecting plates to adjust and clamping components 7 according to the size, position, and thickness of the microwave absorbing material patch 2.

[0015] The machine body upper surface is also provided with a moving clamping mechanism 3 for clamping the test wave-absorbing material patch 2, which can manually move and clamp according to the length of the test wave-absorbing material patch 2. The moving clamping mechanism 3 comprises a sliding rail 31 and a moving clamping component 4 installed in cooperation with the sliding rail 31. The sliding rail 31 is arranged in pairs and the bottom surface is adhered to the upper surface of the machine body by an adhesive layer 211, and of course, it can also be installed in place of a fastener such as a screw. The moving clamping component 4 comprises a manual threaded rod, a threaded moving part 5, a connecting plate component 6 and a clamping component 7. The manual threaded rod is connected to the sliding rail 31. The inside of the sliding rail 31 is separated by a partition 32, which divides the sliding rail 31 into a transmission cavity one 33 and a transmission cavity two 34, each of which has a moving port 62 on the inner side. The partition 32 is provided with a shaft tube 36 on both sides. The transmission cavity one 33 and the transmission cavity two 34 are both connected with a matched shaft tube 37 corresponding to the shaft tube 36. The threaded moving part 5 is screwed on the manual threaded rod. The manual threaded rod is connected to the transmission cavity one 33 and the transmission cavity two 34, respectively. The inner end and the outer end are respectively provided with a shaft column one 42 and a shaft column two 43 connected to the shaft tube 36 and the matched shaft tube 37. Both of them can be installed with a ball bearing shaft. The outer end of the shaft column two 43 is provided with a stud 44 penetrating through the matched shaft tube 37. The outer end of the stud 44 is provided with a handle 45. The stud 44 is provided with a flange nut 46.

[0016] The transmission principle of the above moving clamping component is that the threaded direction of the manual threaded rod arranged in the transmission cavity one is spirally arranged from left to right. The threaded direction of the manual threaded rod arranged in the transmission cavity two is spirally arranged from right to left. Therefore, manually operating the manual threaded rod connected to the transmission cavity one and two respectively makes the threaded moving part move from the outer end to the inner end. When the rotating position needs to be fixed, it is fixed by the flange nut.

[0017] Further, in order to facilitate the replacement of the connecting component, an internal thread tube 51 is arranged at the inner end of the threaded moving part 5, which is convenient for screwing and installing the connecting plate one 60. In order to further improve the fixation of the width of the test wave-absorbing material patch 2, the length of the connecting component is manually adjusted. The connecting component 6 comprises a connecting plate one 60 and a connecting plate two 61. The connecting plate one 60 is a hollow structure, and the outer side is opened for the matching of the connecting plate two 61. The connecting plate two 61 is adjustably installed in the connecting plate one 60. The connecting plate one 60 is screwed on one side of the threaded moving part 5. The inner end of the threaded moving part 5 is provided with an internal thread tube 51. The outer end of the connecting plate one 60 is provided with an external stud 52 screwed and installed with the internal thread tube. The left and right sides of the connecting plate one 60 are provided with moving ports 62. The connecting plate two 61 is provided with a transverse stud 63 moving in the moving port 62, which is fixed by a No. 1 fixed nut 64. The clamping component 7 is adjustably installed at the outer end of the connecting plate two 61. The outer end of the connecting plate two 61 is longitudinally embedded with a longitudinal internal thread tube 65, which is used for manually screwing and adjusting the clamping component according to the thickness of the wave-absorbing material patch, so as to be clamped on the upper surface of the test wave-absorbing material patch 2.

[0018] The clamping component 7 includes a longitudinal stud 71, a clamping plate 72 provided at the bottom end of the longitudinal stud 71, and an operating handle 73 provided at the top end of the longitudinal stud 71. A second fixing nut 74 is mounted on the longitudinal stud 71. The clamping component 7 is used to clamp on the upper surface of the test wave-absorbing material patch 2.

[0019] Working principle: The present application is used for testing the use of the wave-absorbing material patch on the unmanned aerial vehicle. When testing the wave-absorbing material patch with different lengths, widths and thicknesses, the mobile clamping mechanism is used to manually adjust according to the length of the test wave-absorbing material patch. In use, the transmission principle of the mobile clamping component described in Embodiment I can be operated.

[0020] The connecting plate component screwed on the screwing mobile part on the mobile clamping mechanism is manually adjusted according to the width of the test wave-absorbing material patch. The connecting plate component is manually adjusted between the connecting plate two and one to make the transverse stud fixed by the nut after moving in the mobile port.

[0021] The clamping component screwed in the connecting plate two in the connecting plate component is manually adjusted according to the thickness of the test wave-absorbing material patch. The clamping component is manually adjusted by screwing the longitudinal stud in the longitudinal inner screw tube. Since the height of the longitudinal stud is higher than that of the longitudinal inner screw tube, it is easy to manually operate the handle to adjust the height and be fixed by the fixing nut.

[0022] The above is the principle of adjusting the fixing according to the length, width and thickness of the test wave-absorbing material patch. In this way, it is not necessary to tear the back glue of the wave-absorbing material patch, but only to adjust the clamping and fixing to achieve convenience. The test wave-absorbing material patch can be used after testing, and it is also convenient to replace different test wave-absorbing material patches for testing.

It should be noted that the above preferred embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable persons skilled in the art to understand the content of the present application and implement it, and it cannot limit the protection scope of the present application.
