It can command and guide pedestrians and vehicles by voice during peak traffic hours to relieve traffic congestion. Its structure includes a fuselage, rotors, a sensor system, and an adjustable speaker, and is applicable to various occasions such as urban roads, construction sites, and large-scale events, and can achieve remote control and intelligent scheduling.

[0003] However, there are obvious technical problems in the installation method of the existing traffic guidance UAV's speaker. Currently, the speaker is fixed below the UAV by a threaded connection, and this connection method is very inconvenient in practical applications. Since the UAV frequently ascends, descends, and moves during operation, the threaded connection easily causes the speaker to loosen or fall off, thus affecting the stability and effect of voice command, and further reducing the application efficiency and reliability of the UAV in traffic management.

[0004] In view of the above problems, a traffic guidance UAV is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a traffic guidance UAV, aiming to solve the problem that due to the frequent ascending, descending, and moving of the UAV during operation, the threaded connection easily causes the speaker to loosen or fall off, thus affecting the stability and effect of voice command, and further reducing the application efficiency and reliability of the UAV in traffic management.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] Referring to Figure 1 - Figure 6 , an embodiment provided by the present utility model: a traffic guidance drone, comprising:

[0036] A drone body 1, a camera 2 is assembled on the front side of the drone body 1, a fixed platform 7 is fixedly connected to the bottom of the drone body 1, an annular fixed seat 9 is installed outside the fixed platform 7, a loudspeaker 6 is arranged below the annular fixed seat 9, and a support assembly for providing support is arranged below the drone body 1;

[0037] A quick-release assembly for quickly installing and disassembling the loudspeaker 6, which can save a lot of time compared with the traditional bolt installation. It is installed below the fixed platform 7. Embedded fixing blocks 12 are fixedly connected to the inner circumferences of the inner sides of the annular fixed seat 9. A hemispherical groove 13 is opened inside the embedded fixing block 12. A connecting cylinder 8 is threadedly connected to the top of the loudspeaker 6. U-shaped fixing blocks 10 are assembled on the outer circumferences of the outer sides of the connecting cylinder 8. An outer cylinder 11 is fixedly connected to the inside of the U-shaped fixing block 10. A ball seat 16 is slidably connected to the inside of the outer cylinder 11. A ball 14 is installed at the bottom of the ball seat 16. The outer side of the ball 14 abuts against the inside of the hemispherical groove 13. A strong magnet 15 is fixedly connected to the inside of the embedded fixing block 12. The ball 14 is made of a metal material that can be magnetically attracted. A spring 17 is fixedly connected to the top of the ball seat 16. The top of the spring 17 is fixedly connected to the inner top wall of the outer cylinder 11. Two symmetrically distributed limiting blocks 19 are fixedly connected to the side wall of the ball seat 16. A sliding groove 18 is opened on the inner wall of the outer cylinder 11. The outer side of the limiting block 19 is slidably connected to the inside of the sliding groove 18. The ball 14 can freely rotate inside the ball seat 16.

[0038] Specifically, in this embodiment, a camera 2 is assembled on the front side of the unmanned aerial vehicle body 1. To facilitate the real-time detection of traffic conditions on the road surface, a fixed platform 7 is fixed at the bottom of the unmanned aerial vehicle body 1. An annular fixing seat 9 is installed on the outer side of the fixed platform 7. Embedded fixing blocks 12 are provided on the inner sides of the four circumferences of the annular fixing seat 9, and hemispherical grooves 13 are opened inside the embedded fixing blocks 12. The loudspeaker 6 is threadedly connected to the bottom of the connecting cylinder 8. To quickly install the loudspeaker 6 to the bottom of the unmanned aerial vehicle body 1, four U-shaped fixing blocks 10 are assembled on the outer side of the connecting cylinder 8, and outer cylinders 11 are fixed inside the U-shaped fixing blocks 10. The user can pass the four U-shaped fixing blocks 10 on the outer side of the connecting cylinder 8 through the gaps between the embedded fixing blocks 12, ensuring that the horizontal position of the ball 14 at the bottom of the connecting cylinder 8 is above the embedded fixing blocks 12. Then, the connecting cylinder 8 is rotated. The ball 14 rolls inside the ball seat 16, and the ball 14 slides outward into the outer cylinder 11 under the pressure from the top of the embedded fixing block 12 and compresses the spring 17. When the ball 14 slides into the hemispherical groove 13, since the material of the ball 14 is also attracted by the strong magnet 15, finally, the connecting cylinder 8 and the loudspeaker 6 at the bottom are both fixed under the unmanned aerial vehicle body 1, saving a large amount of time compared with the traditional bolt connection.

[0039] Referring to Figure 1 - Figure 2 , the support assembly includes two fixed rods 5. The two fixed rods 5 are respectively fixed on both sides of the unmanned aerial vehicle body 1. The bottom of the fixed rod 5 is fixedly connected with a telescopic support rod 4. A support frame 3 is fixedly connected between the bottoms of the two telescopic support rods 4. The support frame 3 is annular and can provide more stable support.

[0040] Specifically, fixed rods 5 are fixed on both sides of the unmanned aerial vehicle body 1, and telescopic support rods 4 that can freely expand and contract under force are fixed at the bottoms of the fixed rods 5, which can effectively reduce the pressure when the unmanned aerial vehicle body 1 lands, ensure the stability of the device, and a support frame 3 is connected to the bottom of the telescopic support rod 4 to provide effective support after the unmanned aerial vehicle body 1 lands.

[0041] Working principle: When observing road conditions, the unmanned aircraft body 1 can provide a wider perspective and sufficient convenience. A camera 2 is installed on the front side of the unmanned aircraft body 1 to transmit road conditions in real time. In order to more effectively dredge traffic, a speaker 6 is assembled at the bottom of the unmanned aircraft body 1, which can effectively remind and warn drivers. Compared with bolt fixation, this embodiment adopts a more rapid method. Only need to thread-fix the speaker 6 at the bottom of the connecting cylinder 8. By using the outer cylinder 11 fixed to the outside of the connecting cylinder 8, when the connecting cylinder 8 is rotated, the balls 14 at the bottom of the outer cylinder 11 can slide into the embedded fixing blocks 12 inside the annular fixing seat 9. Since the embedded fixing blocks 12 can fit inside the hemispherical grooves 13 and are attracted by the powerful magnets 15, it can ensure that the speaker 6 is stably installed at the bottom of the unmanned aircraft body 1, saving a large amount of installation time. And in order to protect the unmanned aircraft body 1, telescopic support rods 4 are installed on both sides of the bottom of the unmanned aircraft body 1, which can effectively reduce the damage to the unmanned aircraft body 1 caused by the impact force during landing. The support frame 3 can provide stable support.
