Description

Technical Field

[0001] This utility model is a multi-angle wind resistance testing device for unmanned aerial vehicles (UAVs), belonging to the field of UAV technology. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and onboard program control devices, or operated autonomously by an onboard computer, either completely or intermittently. They have applications in fields such as aerial photography, agriculture, plant protection, miniature selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying, news reporting, power line inspection, disaster relief, film and television shooting, and creating romance, greatly expanding the uses of drones. Developed countries are also actively expanding industry applications and developing drone technology.

[0003] Publication number CN217738609U mentions a multi-angle wind resistance testing device for drones. Through the cooperation of various structures in the rotating mechanism, wind can be blown out at different angles through the air outlet sleeve. Compared with traditional drone wind resistance testing devices, this device can blow wind from multiple angles, simulating the external flight environment of drones. This allows for testing of drones from multiple angles, resulting in more comprehensive and accurate test results. However, when testing the wind resistance of drones, the drone is close to the wind-resistant equipment structure. If the user operates it improperly, the drone propeller may touch the surface of the wind-resistant equipment, which may cause safety hazards. There is an urgent need for a multi-angle wind resistance testing device for drones to solve the above-mentioned problems. Utility Model Content

This invention is highly practical. The distance between the lower and upper multi-angle wind-blowing support frames can be adjusted via an electric push rod, allowing the lower and upper multi-angle wind-blowing support frames to be positioned away from the UAV while still enabling wind resistance testing. The test jet head, powered by a motor, can perform multi-angle tests on the UAV, thereby increasing the UAV's flight space.

[0007] Furthermore, a support ring is fixedly connected to the upper end of the docking rotating base, and the support ring is rotatably connected to the support rotating base.

[0008] Furthermore, an annular groove is formed on the circumferential surface of the support pivot, and the sliders at the right ends of the two multi-angle air blowing support frames are slidably connected to the annular groove.

[0009] Furthermore, a lifting box is fixedly connected to both the front and rear ends of the wind resistance test base, and a positioning block is fixedly connected to both the front and rear ends of the wind resistance test base.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-5This utility model provides a technical solution: a multi-angle wind resistance capability testing device for unmanned aerial vehicles (UAVs), including a wind resistance testing base 1. A fixed support rod 6 is fixedly connected to the upper right end of the wind resistance testing base 1, and a support rotating seat 5 is fixedly connected to the upper end of the fixed support rod 6. A support rotating rod 15 is rotatably connected inside the wind resistance testing base 1, and a second gear 16 is fixedly connected to the circumferential surface of the support rotating rod 15. A motor 13 is fixedly connected to the lower interior of the wind resistance testing base 1, and a first gear 14 is fixedly connected to the output end of the motor 13. The second gear 16 meshes with the first gear 14. A docking rotating base is fixedly connected to the upper end of the support rotating rod 15. The left end of the rotating base 17 is fixedly connected to two multi-angle air blowing lower support frames 7. The left end of each of the two multi-angle air blowing lower support frames 7 is fixedly connected to an electric push rod 10. The output end of each of the two electric push rods 10 is fixedly connected to a multi-angle air blowing upper support frame 8. The left end of both the two multi-angle air blowing upper support frames 8 and the two multi-angle air blowing lower support frames 7 is fixedly connected to multiple test jet heads 9. This design solves the problem that when the original device tests the wind resistance capability of the drone, the distance between the drone and the wind resistance equipment structure is close, and if the user operates it improperly, the drone propeller will touch the surface of the wind resistance equipment, which is easy to cause safety hazards.

[0022] As the first embodiment of this utility model: A supporting rotating ring 18 is fixedly connected to the upper end of the docking rotating base 17. The supporting rotating ring 18 is rotatably connected to the supporting rotating seat 5. The supporting rotating ring 18 installed on the docking rotating base 17 can support the protective base 4 and limit the rotation of the multi-angle blowing support frame 7 on the wind-resistant test base 1. An annular rotating groove 12 is opened on the circumferential surface of the supporting rotating seat 5. The sliders at the right ends of the two multi-angle blowing support frames 7 are slidably connected to the annular rotating groove 12. The annular rotating groove 12 on the surface of the supporting rotating seat 5 can support the multi-angle blowing support frame 7 to rotate on the wind-resistant test base 1. Lifting and placing boxes 2 are fixedly connected to both the front and rear ends of the wind-resistant test base 1. Positioning and fixing blocks 3 are fixedly connected to both the front and rear ends of the wind-resistant test base 1. The lifting and placing boxes 2 installed on the surface of the wind-resistant test base 1 make it convenient for users to hook the lifting and placing boxes 2 to lift and move the equipment. The positioning and fixing blocks 3 installed on the surface of the wind-resistant test base 1 can fix the wind-resistant test base 1 on the workbench with screws so that the equipment can operate stably. A protective base 4 is fixedly connected to the upper end of the support rotator 5.

The front ends of the two multi-angle blowing upper support frames 8 and the two multi-angle blowing lower support frames 7 are all connected to air inlet pipes 11. The air inlet pipes 11 installed on the surface of the multi-angle blowing upper support frame 8 and the multi-angle blowing lower support frame 7 can provide airflow to the test jet head 9. When testing the drone, the multiple test jet heads 9 can blow airflow onto the drone.

[0023] As a second embodiment of this utility model: First, place the drone on the protective base 4, then control the drone to suspend in the air, and at the same time control the electric push rod 10 to push the multi-angle blowing upper support frame 8 upward, so that multiple test jet nozzles 9 blow air onto the drone from behind. The user records the drone's status. When it is necessary to change the direction of the air nozzles, the user can control the motor 13 to drive the first gear 14 to rotate, so that the support rotating rod 15 drives the multi-angle blowing lower support frame 7 to slowly rotate on the surface of the wind-resistant test base 1, blowing the airflow onto the drone from multiple angles. After the test is completed, control the drone to stay on the protective base 4, and then control the electric push rod 10 to reset, thus completing the test.
