[0047] Example 1

[0048] This embodiment provides a drone detection device. (Refer to...) Figures 1 to 7 As shown, the UAV testing device includes a base frame 100, a enclosure assembly 200, a blowing assembly 300, a drive assembly 400, and a testing assembly. The enclosure assembly 200 is mounted on the base frame 100 and has an experimental space for placing the UAV. The blowing assembly 300 is mounted on the enclosure assembly 200 and blows air into the experimental space. The drive assembly 400 is mounted on the enclosure assembly 200 and drives the blowing assembly 300 to blow air into the experimental space. The testing assembly includes a wind speed detector 510 and a wind resistance probe 520. A support plate 110 is mounted on the base frame 100 and has a cross groove 111. The wind speed detector 510 is slidably mounted in the cross groove 111. A movable assembly 600 is mounted on the enclosure assembly 200 and the wind resistance probe 520 is mounted on the movable assembly 600. The movable assembly 600 can adjust the orientation of the wind resistance probe 520.

[0049] In this embodiment, when performing wind resistance testing on a drone, the drone is first placed in the experimental space. Then, the drive component 400 is controlled to drive the blowing component 300, so that the blowing component 300 blows air into the experimental space to simulate the wind environment in which the drone is located. Then, the drone is controlled to take off in the experimental space. During the process, the relevant operators control the wind speed detector 510 to slide in the cross groove 111 of the support plate 110 to change the angle position of the wind speed detector 510 relative to the drone. The movable component 600 is controlled to change the orientation position of the wind resistance probe 520 relative to the drone. The different position adjustments of the wind speed detector 510 and the wind resistance probe 520 relative to the drone can observe the wind resistance status of the drone at different angles, further ensuring the detection effect of the wind resistance status of the drone.

[0050] In this embodiment, the principle and specific process of the wind speed detector 510 and the wind resistance probe 520 working together to detect the wind resistance status of the UAV are existing technologies and will not be described in detail here.

[0051] Furthermore, referring to Figure 2 , Figure 6 As shown, the base frame 100 has a mounting groove 101, and the support plate 110 has a corresponding mounting head 112. The mounting head 112 is inserted into the mounting groove 101. This configuration is simple and easy to install.

[0052] In this embodiment, the main frame structure of the base frame 100 is set as a rectangle, and each of the four corners of the rectangular main frame structure is provided with a support leg 120, so that the entire UAV detection device can be reliably and stably supported on the ground.

[0053] Furthermore, referring to Figure 1 , Figure 3 As shown, the enclosure assembly 200 includes a first baffle 210 and a second baffle 220. Two first baffles 210 are provided and spaced apart on the base frame 100 along a first direction. Two second baffles 220 are provided and spaced apart on the base frame 100 along a second direction. The first baffles 210 and the second baffles 220 can jointly enclose an experimental space, with the first direction perpendicular to the second direction.

[0054] In this embodiment, the two first baffles 210 and the two second baffles 220 can together form a rectangular structure that is compatible with the rectangular main frame on the base frame 100, and the first baffles 210 and the adjacent second baffles 220 are fixed to each other to ensure the airtightness of the enclosed experimental space.

[0055] Furthermore, referring to Figure 1 , Figure 4As shown, the blower assembly 300 includes a ventilation mesh plate 310 and a fan 320. The first baffle 210 and the second baffle 220 are both provided with mounting ports 201. The ventilation mesh plate 310 is fixedly covered on the mounting port 201. A plug-in shaft 311 is rotatably provided on the ventilation mesh plate 310, and the fan 320 is fixedly sleeved on the plug-in shaft 311.

[0056] Specifically, the ventilation mesh 310 can protect the fan 320 on the one hand, avoiding the risk of accidental injury from personnel touching the fan 320 when it is rotating; on the other hand, it can provide a certain rectification effect to the air inlet of the fan 320, making the airflow blown into the experimental space by the fan 320 more stable and reliable.

[0057] Furthermore, a limiting ring 330 is also fitted on the end of the plug shaft 311 away from the ventilation mesh plate 310 of the fan 320, and the limiting ring 330 is threadedly connected to the plug shaft 311.

[0058] Specifically, the limiting ring 330 is adapted to be screwed onto the end of the plug shaft 311 after the fan 320 is fixedly inserted into the plug shaft 311 and threadedly connected to the plug shaft 311. It can reliably limit the fan 320 on the plug shaft 311, prevent the fan 320 from accidentally falling off during the rotation of the fan 320 driven by the plug shaft 311, and further ensure the reliability of the fan 320 during rotation.

[0059] Furthermore, referring to Figure 1 , Figure 5 As shown, the drive assembly 400 includes a drive shaft 410 and a drive motor 420. There are two drive shafts 410. One drive shaft 410 extends along a first direction and is disposed between two first baffles 210, and the other drive shaft 410 extends along a second direction and is disposed between two second baffles 220. The ends of both drive shafts 410 are connected to the drive motor 420. Each drive shaft 410 is provided with two transmission assemblies that are respectively connected to two plug-in shafts 311 in the extension direction.

[0060] In this embodiment, the drive motor 420 is configured as a servo motor, which can adaptively adjust the speed and direction.

[0061] In this embodiment, one drive motor 420 is disposed on the side of one of the first baffles 210 away from the experimental space, and the other drive motor 420 is disposed on the side of one of the second baffles 220 away from the experimental space. This arrangement can minimize the occupation of experimental space by the drive motors 420 and avoid encroaching on the flight space of the UAV.

[0062] Specifically, both the first baffle 210 and the second baffle 220, on which the drive motor 420 is installed, have through holes 202. The end of the drive shaft 410 corresponding to the drive motor 420 passes through the corresponding through hole 202 and is then connected to the output shaft 421 of the corresponding drive motor 420.

[0063] Furthermore, the output shaft 421 of the drive motor 420 is provided with a insertion slot, and the inner sidewall of the insertion slot is provided with a keyway 4211. The end of the drive shaft 410 is correspondingly provided with a locking key 4101. When the drive shaft 410 is inserted into the insertion slot, the locking key 4101 at the end of the drive shaft 410 will be inserted into the keyway 4211, thereby making the connection between the drive shaft 410 and the output shaft 421 of the drive motor 420 more secure and reliable.

[0064] This embodiment is not limited thereto. The drive shaft 410 and the output shaft 421 of the drive motor 420 can also be connected by a coupling or other components. No further limitations are imposed here.

[0065] Specifically, the transmission assembly includes a first bevel gear 431, a second bevel gear 432, a transmission shaft 433, a third bevel gear 434, and a fourth bevel gear 435. The first bevel gear 431 is fixedly sleeved on the drive shaft 410, the fourth bevel gear 435 is fixedly sleeved on the insertion shaft 311, the second bevel gear 432 and the third bevel gear 434 are respectively fixedly sleeved on opposite ends of the transmission shaft 433, the first bevel gear 431 is meshed with the second bevel gear 432, and the third bevel gear 434 is meshed with the fourth bevel gear 435.

[0066] Specifically, the rotation of the output shaft 421 of the drive motor 420 can drive the drive shaft 410 to rotate synchronously, thereby driving the two first bevel gears 431 connected to the same drive shaft 410 to rotate. The rotation of the two first bevel gears 431 can drive the corresponding second bevel gears 432 to rotate, and then drive the two corresponding fourth bevel gears 435 to rotate via the corresponding transmission shaft 433 and the third bevel gear 434, which in turn drive the plug shaft 311 to rotate so as to drive the fan 320 to rotate reliably.

[0067] In this embodiment, reference is made to Figure 1 , Figure 7As shown, the movable component 600 includes a fixed post 610, a vertical rod 620, and a rotating bar 630. The fixed post 610 is fixedly mounted on the enclosure component 200. The first end of the vertical rod 620 is rotatably inserted into the fixed post 610. The second end of the vertical rod 620 is hinged to the first end of the rotating bar 630 via a hinge 640. A wind resistance probe 520 is fixedly mounted on the second end of the rotating bar 630. Specifically, the vertical rod 620 can rotate around the axial direction of the fixed post 610, and the vertical rod 620 and the rotating bar 630 can rotate around the axial direction of the hinge 640. That is, the movable component 600 can provide the wind resistance probe 520 with rotational freedom in two directions, which can further ensure that the wind resistance probe 520 can flexibly adjust its direction.

[0068] In this embodiment, the hinge 640 can be a pin or a bolt assembly, and no further limitations are imposed here.

[0069] In this embodiment, the fixed column 610 and the vertical rod 620 are rotatably connected by a bearing 650. The bearing 650 is preferably a cylindrical roller bearing.

[0070] Further integration Figure 3 As shown, an assembly hole 203 is provided on one of the first baffles 210 or the second baffle 220, and the fixing post 610 can be reliably inserted into the assembly hole 203. The structure is simple and easy to assemble and disassemble.

[0071] Example 2

[0072] Reference Figure 8 As shown, the difference between this embodiment and embodiment one is that the support plate 110 in embodiment one is replaced by the first servo module and the second servo module in this embodiment.

[0073] Specifically, the first servo module includes a first slide rail 131 and a first sliding part 132, and the second servo module includes a second slide rail 133 and a second sliding part 134. The first slide rail 131 extends along a first direction and is fixed to the base frame 100. The first sliding part 132 is slidably disposed on the first slide rail 131. The second slide rail 133 extends along a second direction and is fixed to the first sliding part 132. The second sliding part 134 is slidably disposed on the second slide rail 133. The wind speed detector 510 is fixedly disposed on the second sliding part 134. In this embodiment, the first servo module enables the first sliding part 132 to slide automatically relative to the first slide rail 131, and the second servo module enables the second sliding part 134 to slide automatically relative to the second slide rail 133. This configuration enables automatic adjustment of the position of the wind speed detector 510 on the base frame 100, making the movement and adjustment process of the wind speed detector 510 more efficient and convenient, and increasing the overall automation level of the device.

[0074] Both the first and second servo modules are configured as linear servo modules, which will not be elaborated on here.

[0075] Furthermore, mounting heads 112 are also provided at opposite ends of the first slide rail 131, which can reliably connect to the mounting groove 101 on the base frame 100 without changing the external structure of the base frame 100, thereby achieving a reliable connection with the base frame 100.

[0076] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
