[0002] With the rapid development of drone technology, drones are increasingly used in various fields, including agriculture, logistics, surveying and mapping, film and television shooting, emergency rescue, etc. In order to ensure the flight safety and performance of drones, drone testing has become a crucial link. Traditional drone testing methods mainly rely on outdoor flight tests, which are not only limited by weather and geographical environment, but also have certain safety risks during the testing process. At the same time, outdoor testing is difficult to simulate complex flight environments and extreme conditions, which limits the comprehensiveness and accuracy of the test. In recent years, indoor drone testing platforms and facilities have begun to attract attention. They test the performance and stability of drones by building simulated environments.

[0003] After searching, it is found that a UAV vibration test device is disclosed in the utility model with authorization announcement number CN218617218U. The device clamps and fixes the wings of the UAV through a fixing box, a clamping plate, a guide rod, a turbine, a spur plate, a worm and a linkage gear, thereby achieving a stable clamping function of the UAV. However, in actual use, the above-mentioned side view device still has the following defects:

[0004] 1. The outer shell surface of the above-mentioned drone is usually a curved surface. Since the surface of the clamping plate is a flat surface, the contact area between the clamping plate and the drone wing is limited, which makes the drone unstable during the vibration test, thereby affecting the accuracy of the test results;

[0005] 2. The simulation degree of the test environment is low and cannot truly reflect the various situations that the drone may encounter in actual flight.

[0006] Therefore, the utility model proposes a drone testing device to perform drone testing more comprehensively, accurately and safely, thereby solving the problems existing in the above-mentioned prior art. Utility Model Content

[0007] In view of this, the main purpose of the utility model is to provide a drone testing device.

[0043] Embodiment 1:

[0044] See also Figures 1 to 6 , a UAV testing device, comprising:

[0045] A vibration test bench 1, wherein a connecting frame 2 is rotatably connected to the upper end of the surface of the vibration test bench 1, and a placing plate 3 is rotatably connected to the top end of the connecting frame 2;

[0046] The clamping mechanism 4 is arranged on the placement plate 3 and is used in conjunction with the drone 5 , and the placement plate 3 is installed at the lower end of the clamping mechanism 4 .

[0047] When the UAV 5 needs to be subjected to a vibration test, the UAV 5 is placed on the placement plate 3, the placement plate 3 is connected to the UAV 5 using the clamping mechanism 4, the vibration test bench 1 is manually turned on, and the UAV is subjected to a vibration test using the digital twin simulation test system in the vibration test bench 1. The test data is displayed on the display screen on the vibration test bench 1 for the test personnel to view and record.

[0048] See also Figure 3 , Figure 4 and Figure 5 , the clamping mechanism 4 is arranged on the placement plate 3, and includes a driving block 41 and two clamping frames 44;

[0049] The driving block 41 is rotatably connected to the inner wall of the placement plate 3, and two driven blocks 42 are rotatably connected to both ends of the driving block 41;

[0050] The two clamping frames 44 are slidably installed on the placement plate 3 through the sliding groove 43 on the placement plate 3. The lower end of the clamping frame 44 is hingedly connected to the free end of the driven block 42, and clamping blocks 412 are fixedly connected to the front and rear ends of the clamping frame 44. The surface of the clamping block 412 is curved in an arc shape and the clamping block 412 is a rubber component, and is used in conjunction with the drone bracket arranged on the lower side of the drone 5.

[0051] When the drone needs to be subjected to a vibration test, the drone 5 is placed on the placement plate 3, and the driving block 41 is rotated. The driving block 41 rotates to pull the two driven blocks 42 to move, and the driven block 42 moves to pull the clamp frame 44 and the clamp block 412 to move, so that the two groups of clamp blocks 412 are close to each other and clamp the bracket under the drone. Because the surface of the clamp block 412 is curved in an arc shape and the clamp block 412 is a rubber component, the contact area between the clamp block 412 and the bracket under the drone can be increased, so that the drone can be stably clamped on the upper end of the placement plate 3.

[0052] like Figure 4 As shown, two limit frames 45 and four fixing seats 413 are fixedly connected to the top of the placement plate 3. The limit frame 45 is movably arranged between two adjacent fixing seats 413 and is used in conjunction with the drone bracket arranged on the lower side of the drone 5. A blocking rod 46 is also fixedly connected to one side of the limit frame 45 and is used in conjunction with the fixing seat 413. The position of the limit frame 45 on the placement plate 3 is adjusted by adjusting the position of the blocking rod 46 on the fixing seat 413.

[0053] like Figure 5 As shown, the upper surface end of the driving block 41 is fixedly connected with a toggle rod 47, and the toggle rod 47 is threadedly connected with a screw 48. The lower surface end of the screw 48 is clamped on the top of the placement plate 3, and the top of the placement plate 3 is also fixedly connected with a spacer block 411. The surface of the toggle rod 47 contacts one side of the spacer block 411, and the lower surface end of the screw 48 is fixedly connected with a connecting block 410. The upper surface end of the screw 48 is fixedly connected with a fixing rod 49, and the lower surface end of the screw 48 is bent in an arc shape.

[0054] When in use, the toggle rod 47 rotates and contacts the spacer block 411, and the toggle rod 47 stops rotating, so that the clamping block 412 is clamped on the drone bracket below the drone 5, and the screw rod 48 is rotated. The screw rod 48 rotates and moves downward on the toggle rod 47 to accurately get stuck in the top limit hole 34 of the placement plate 3, thereby locking the drive block 41.

[0055] Embodiment 2

[0056] See also Figure 1 and Figure 2, which is different from the above-mentioned embodiment 1, is that a first servo motor 21 is fixedly connected to one side of the vibration test table 1, the output shaft of the first servo motor is fixedly connected to a first bevel gear 22, the top end of the first bevel gear 22 is meshedly connected to a second bevel gear 23, and the inner wall of the second bevel gear 23 is fixedly connected to the surface of the connecting frame 2.

[0057] A second servo motor 31 is also fixedly connected to the inner side of the connecting frame 2, and a third bevel gear 32 is fixedly connected to the output shaft of the second servo motor 31. One end of the third bevel gear 32 is meshedly connected to a fourth bevel gear 33, and the top end of the fourth bevel gear 33 is fixedly connected to the bottom end of the placement plate 3.

[0058] When the drone needs to be subjected to a vibration test, the drone 5 is fixed on the placement plate 3; the first servo motor 21 is turned on, and the output shaft of the first servo motor 21 rotates through the first bevel gear 22 and the second bevel gear 23, driving the connecting frame 2 and the placement plate 3 to tilt at an angle, thereby changing the tilt angle of the drone 5.

[0059] The second servo motor 31 is turned on, and the output shaft of the second servo motor 31 rotates through the third bevel gear 32 and the fourth bevel gear 33 to drive the placement plate 3 to rotate, thereby adjusting the flight angle function of the drone 5 .

[0060] Finally, the vibration test bench 1 is turned on to perform a vibration test on the drone, and the test data is displayed on the display screen on the vibration test bench 1 for the tester to watch and record. After the vibration test is completed, the first servo motor 21, the second servo motor 31 and the vibration test bench 1 are turned off.

[0061] When the utility model is in use, the drone is placed on the placement plate 3, and the position of the drone on the placement plate 3 is limited by two limit frames 45. At this time, the drone is pushed so that the bracket below the drone contacts the blocking rod 46, so that the drone is placed in the center of the placement plate 3, and the toggle rod 47 is rotated. The toggle rod 47 rotates to drive the driving block 41 to rotate, and the driving block 41 rotates to pull the two driven blocks 42 to move, and the driven block 42 moves to pull the clamping frame 44 and the clamping block 412 to move, so that the two groups of clamping blocks 412 are mutually Approach and clamp the bracket under the drone. Since the surface of the clamp block 412 is curved in an arc shape and the clamp block 412 is a rubber component, the contact area between the clamp block 412 and the bracket under the drone is increased. The toggle rod 47 rotates and contacts the spacer 411. The rotation of the toggle rod 47 is stopped, so that the clamp block 412 clamps the bracket under the drone. The screw rod 48 is rotated and moved downward on the toggle rod 47 to be accurately clamped on the top of the placement plate 3. The drive block 41 is locked, so that the drone is stably clamped on the top of the placement plate 3.

[0062] It should be noted that the first servo motor 21, the second servo motor 31 and the vibration test bench 1 in the above description are all devices with relatively mature application of existing technologies. The specific models can be selected according to actual needs. At the same time, the first servo motor 21, the second servo motor 31 and the vibration test bench 1 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
