[0002] Drone detection refers to the process of detecting, identifying, and tracking aerial drones using various technical means. These detection technologies each have their own advantages and disadvantages and are suitable for different scenarios and needs. For example, radar detection is suitable for long-distance and high-altitude targets, while photoelectric detection is more suitable for daytime and nighttime use. With the development of technology, the application of multi-source data fusion and artificial intelligence algorithms has made drone detection more intelligent and efficient.

[0003] When drones are conducting reconnaissance, they need to carry additional detection equipment.

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.

[0021] As shown in Figures 1 to 4, the present invention provides a drone detection auxiliary device, including a drone body 1. A mounting frame 2 is fixedly connected to the bottom of the drone body 1. A U-shaped box 3 is fixedly connected to the bottom of the mounting frame 2. A rotating block 4 is movably connected to the rear side of the U-shaped box 3 via a bearing.

A helical gear 9 meshes on the front side of the helical gear 8. A screw 10 is fixedly connected to the front side of the helical gear 9. The front side of the screw 10 is movably connected to the front side of the inner wall of the U-shaped box 3 via a bearing. A screw sleeve 11 is threadedly connected to the surface of the screw 10. A rectangular rod 12 is fixedly connected to the inner side of the screw sleeve 11. A lateral adjustment mechanism 18 is sleeved on the surface of the rectangular rod 12.

[0022] Referring to Figure 4, the lateral adjustment mechanism 18 includes a rectangular sleeve 181 that is slidably connected to the surface of the rectangular rod 12. Both the front and rear sides of the rectangular sleeve 181 are threaded with screws 182. The inner side of the screws 182 extends into the interior of the rectangular sleeve 181 and is fixedly connected with a friction block 183. The bottom of the rectangular sleeve 181 is fixedly connected with a detector mounting bracket 184.

[0023] As a technical optimization of this utility model, by setting the lateral adjustment mechanism 18, the position of the detection device can be adjusted laterally, thereby increasing the adjustment range of the detection device position.

[0024] Referring to Figure 1, the bottom of the U-shaped box 3 is fixedly connected with two support legs 13.

[0025] As a technical optimization of this utility model, by setting the support legs 13, the drone body 1 can be supported, preventing the detection equipment from landing first when the drone body 1 takes off and lands.

[0026] Referring to Figure 1, the bottom of the support leg 13 is fixedly connected with an anti-slip pad 14.

[0027] As a technical optimization of this utility model, by setting the anti-slip pad 14, the friction between the outrigger 13 and the ground can be increased, preventing the drone body 1 from slipping and deviating during take-off and landing.

[0028] Referring to Figure 4, a knob 15 is fixedly connected to the outside of the screw. The knob 15 is T-shaped.

[0029] As a technical optimization of this utility model, by setting the knob 15, the contact area between the user's hands and the screw 182 can be increased, making it easier for the user to rotate the screw 182.

[0030] Referring to Figure 4, friction strips 16 are fixedly connected to both the front and rear sides of the rectangular rod 12.

[0031] As a technical optimization of this utility model, by setting the friction strip 16, the friction force between the friction block 183 and the rectangular rod 12 can be increased, which makes it more convenient for users to use.

[0032] Referring to Figure 3, the surface of the rotating block 4 is provided with anti-slip texture 17.

[0033] As a technical optimization of this utility model, by setting anti-slip texture 17, the friction between the user's hands and the rotating block 4 can be increased, preventing the rotating block 4 from slipping out of the hand during use.

[0034] The working principle and usage process of this utility model are as follows: In use, firstly, the detection device is fixed to the bottom of the detector mounting bracket 184 using bolts. Next, the rotating block 4 is rotated, which drives the first helical gear 5 to rotate. The first helical gear 5 drives the second helical gear 6 to rotate, which in turn drives the crossbar 7 to rotate. The crossbar 7 drives the third helical gear 8 to rotate, which in turn drives the fourth helical gear 9 and the first screw 10 to rotate. The first screw 10 drives the screw sleeve 11 to move longitudinally, which in turn drives the rectangular rod 12 to move longitudinally. The rectangular rod 12 drives the rectangular sleeve 181, the detector mounting bracket 184, and the detection device to move longitudinally. At this point, the detection device can be moved according to the UAV body 1. The longitudinal position of the detection device is adjusted by adjusting the center of gravity. Then, the rectangular sleeve 181 slides laterally on the surface of the rectangular rod 12. The rectangular sleeve 181 drives the detector mounting bracket 184 and the detection device to move laterally. At this time, the lateral position of the detection device can be adjusted according to the center of gravity of the UAV body 1. After the adjustment is completed, the knob 15 is turned. The knob 15 drives the screw 182 to rotate. The screw 182 moves inward using the thread. The screw 182 drives the friction block 183 to move inward, so that the friction block 183 and the friction strip 16 are tightly fitted. At this time, the rectangular sleeve 181 can be fixed on the rectangular rod 12 to achieve the effect of center of gravity adjustment.

[0035] In summary, this UAV detection auxiliary device, by setting up the UAV body 1, mounting frame 2, U-shaped box 3, rotating block 4, helical gear 1 5, helical gear 2 6, crossbar 7, helical gear 3 8, helical gear 4 9, screw 1 10, screw sleeve 11, rectangular rod 12, and lateral adjustment mechanism 18, solves the problem that when additional detection equipment is mounted, these additional loads will change the original mass distribution of the UAV, causing the overall center of gravity of the UAV to shift, thus reducing the flight stability of the UAV.
