Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-4 This utility model provides an embodiment of a mounting mechanism for flight testing, including a fixed plate 1. A fixing mechanism is installed on the outer side of the fixed plate 1. This fixing mechanism allows for timely adjustment of the fixing method based on whether the drone has a support bracket and the size of the bracket, ensuring better mounting of the mounting mechanism on the drone. A counterweight block 16 is fixedly connected to the outer side of the fixing mechanism. The counterweight block 16 adjusts the weight distribution of the mounting mechanism, preventing one side from being too heavy and affecting the drone's flight. A load-bearing mechanism is installed at the bottom of the fixed plate 1. By adding different counterweights to the load-bearing mechanism, the load capacity of the drone can be tested. A load-bearing mechanism is installed at the bottom of the load-bearing mechanism. The support mechanism reduces the impact force generated when the drone lands. The fixing mechanism includes a connecting component, a telescopic component, a positioning component, and an adjusting component. The telescopic component includes a support plate 4, which is slidably connected to the inside of a fixing plate 1. A fixing strip 8 is fixedly connected to the outside of the support plate 4. The fixing plate 1 provides support for the support plate 4, enabling it to operate stably. The movement of the support plate 4 drives the movement of the fixing strip 8. A slide rail 9 is provided on the outside of the fixing strip 8. A positioning hole 5 is provided on the outside of the support plate 4. The positioning component includes a positioning block 6, which is slidably connected to the outside of the fixing plate 1. The positioning block 6 and the positioning hole 5 are interlocked. The fixing plate 1 is internally equipped with... A spring 7 is provided, and the positioning block 6 is supported by the fixing plate 1 to ensure stable operation. The positioning block 6 and the positioning hole 5 cooperate to fix the support plate 4. The adjustment component includes a bidirectional threaded rod 10, which is rotatably connected inside the fixing bar 8. A worm gear 11 is fixedly connected to the end of the bidirectional threaded rod 10. A worm 12 is rotatably connected inside the fixing bar 8. The worm gear 11 and the worm 12 are interlocked. A handle 13 is fixedly connected to the end of the worm 12. The fixing bar 8 provides support for the bidirectional threaded rod 10 to ensure stable operation. Rotating the handle 13 drives the worm 12 to rotate, and the worm 12 drives the worm gear 11 to rotate. The worm gear 11 drives the bidirectional threaded rod 10 to rotate. The outer side of the bidirectional threaded rod 10 is threaded with a slider 14. The slider 14 is bolted to an arc-shaped block 15. The rotation of the bidirectional threaded rod 10 drives the slider 14 to move inside the slide rail 9. The slider 14 drives the arc-shaped block 15 to move, thereby adjusting the position of the slider 14 according to the size of the drone bracket, so as to facilitate the mounting mechanism to be fixed on the drone. The connecting component includes a connecting plate 2, which is fixedly connected to the top of the fixing plate 1. The top of the connecting plate 2 is threaded with a fixing bolt 3. The connecting plate 2 and the fixing bolt 3 cooperate with each other to fix the mounting mechanism to the bottom of the drone.

[0034] Reference Figure 1 , Figure 3 and Figure 5The load-bearing mechanism includes a load-bearing component, a placement component, and a limiting component. The load-bearing component includes a load-bearing box 17, which is fixedly connected to the bottom of the fixed plate 1. A placement box 21 is slidably connected inside the load-bearing box 17, providing support for the placement box 21 to ensure stable operation. Counterweights are added to the placement box 21 to test the drone's load limit. The placement component includes a partition 22, which is fixedly connected to the inside of the placement box 21. A handle is fixedly connected to the outside of the placement box 21. The partition 22 divides the internal space of the placement box 21, preventing the counterweights from moving freely inside the placement box 21 and affecting the drone's flight status. Limiting holes 23 are provided on the outside of the placement box 21. The limiting component includes a locking seat 25. The seat 25 is fixedly connected to the outside of the bearing box 17. The seat 25 has a sliding limit rod 24 inside, which is engaged with the limit hole 23. The seat 25 has a spring 26 inside, which provides support for the limit rod 24 so that it can run stably. The limit rod 24 and the limit hole 23 cooperate to lock the placement box 21. The spring 26 can reset the limit rod 24 after it is displaced. The load-bearing mechanism also includes a damping rod 18, which is fixedly connected to the bottom of the load box 17. The other end of the damping rod 18 is fixedly connected to a silicone block 19. A compression spring 20 is sleeved on the outer periphery of the damping rod 18. The damping rod 18, the compression spring 20 and the silicone block 19 cooperate to reduce the impact force generated when the UAV lands.

[0035] Working Principle: During use, the fixing method can be selected depending on whether the drone has a support frame. When the drone has no support frame, the mounting mechanism can be fixed to the bottom of the drone using the fixing bolt 3 and connecting plate 2. When the drone has a support frame, pulling the positioning block 6 disengages it from the positioning hole 5, thereby releasing the lock on the support plate 4. Pulling the support plate 4 causes the fixing strip 8 to move. At this time, the position of the fixing strip 8 can be adjusted according to the spacing of the drone support frame. When adjusted to a suitable position, the positioning block 6 is released, and the spring 7 pushes it back to its original position, allowing it to re-engage with the positioning hole 5, thus fixing the support plate 4. By rotating the handle 13, the mounting mechanism can be further secured. The worm gear 12 rotates, which drives the worm wheel 11 to rotate, thereby driving the bidirectional threaded rod 10 to rotate and pushing the slider 14 to move. The slider 14 drives the arc block 15 to move. At this time, the position of the slider 14 can be adjusted according to the size of the drone bracket, so as to facilitate the mounting mechanism to be fixed on the drone. Pull the limit rod 24 to disengage it from the limit hole 23, thereby releasing the lock on the placement box 21. At this time, pull the handle to pull the placement box 21 out of the load-bearing box 17, add different weights of configuration weights into the placement box 21, and put the placement box 21 back into the load-bearing box 17. At this time, the drone load test can be carried out.
