Description

Portable drone signal jamming equipment Technical Field

[0001] This utility model relates to the field of drone countermeasures technology, and in particular to portable drone signal jamming equipment. Background Technology

[0002] To address the control needs of drones, various jamming devices have emerged in existing technologies. A typical example is an electromagnetic signal jammer, which emits electromagnetic waves in specific frequency bands, such as 2.4GHz, 5.8GHz, or the GPS band, to disrupt the communication link between the drone and its remote controller or satellite navigation system. This forces the drone to trigger its fail-safe mechanism, causing it to land or return to base. Such devices typically have multi-band switching capabilities, adaptable to the jamming requirements of different drone models.

[0003] The main problems with existing jamming equipment lie in ease of operation and ergonomic design. Firstly, to achieve long-range directional jamming, the equipment needs to integrate high-power radio frequency modules and heat dissipation structures, resulting in a large and heavy device. During operation, the operator must continuously aim at aerial targets, which can easily cause arm fatigue, especially when dealing with multiple drones or long-duration missions, and may even affect jamming accuracy. Furthermore, existing equipment often relies on external batteries for power, further increasing the overall weight and operational burden. Summary of the Invention

[0004] To overcome the drawbacks of easy operation and fatigue, this utility model provides a portable UAV signal jamming device, which aims to solve the above-mentioned shortcomings.

[0005] A portable drone signal jamming device includes a placement box, a connecting rod, and a threaded cover. The placement box has a hinged cover, which is secured with a buckle. A jamming gun is placed inside the placement box. A stretchable support assembly is provided on the cover. When transporting the jamming gun, all components except the support assembly are placed inside the placement box. When using the jamming gun, the support assembly unfolds and supports a fixing plate. The lower end of the connecting rod passes through the fixing plate and is threadedly connected to the threaded cover. The top of the connecting rod is ball-jointed to a base. Two compression blocks are slidably connected to the base. An adjusting screw is rotatably connected to the base and threadedly connected to the compression blocks. The jamming gun is placed on the base, and the two compression blocks clamp the jamming gun.

[0006] Optionally, the system includes a first support rod, one end of which is rotatably connected to the lid, and the other end of which is slidably connected to a locking rod. A first return spring is sleeved on the locking rod, one end of which is connected to the locking rod, and the other end of which is connected to the first support rod. A second support rod is slidably connected inside the first support rod, and the second support rod has a locking hole. The end of the locking rod is engaged with the locking hole for limiting the engagement. The top of the second support rod together supports the fixing plate. A locking block is rotatably connected to the top of the lid, and the locking block is engaged with the first support rod for limiting the engagement. A pop-out component for ejecting the first support rod is provided in the middle of the lid.

[0007] Optionally, the pop-out component includes a top plate, and a sliding groove is formed inside the box cover. The top plate is slidably connected to the sliding groove, and the top surface of the top plate contacts the first support rod. A second return spring is provided inside the box cover, with one end connected to the top plate and the other end connected to the box cover.

[0008] Optionally, a fastening pad is provided at one end of the second support rod that is connected to the fixing plate, and the fastening pad is pressed and engaged with the fixing plate.

[0009] Optionally, auxiliary plates are snapped onto both sides of the base.

[0010] Optionally, protective pads are connected to adjacent sides of both extrusion blocks.

[0011] Optionally, a rubber sleeve is fitted onto the end of the adjusting screw.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. By combining the retractable support components with the fixed plate, the equipment can be quickly set up and its height can be adjusted. The top fastening pad and the fixed plate form a stable contact surface, replacing the traditional operation of manually holding the jamming gun. This allows the jamming gun to be fixed in the air at a preset height, significantly reducing physical exertion.

[0014] 2. Connected to the connecting rod via a ball joint, it supports 360° horizontal rotation and ±90° pitch adjustment of the jamming gun. Operators can lock the target direction with one hand without continuously adjusting the gun's angle, achieving multi-angle rapid aiming and hands-free operation. Attached Figure Description

It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0024] Example: A portable UAV signal jamming device, as shown in Figures 1-6, includes a placement box 1, a box cover 2, a jamming gun 3, a support assembly, a fixing plate 9, a connecting rod 10, a threaded cover 11, a base 12, an adjusting screw 13, and pressing blocks 14. The placement box 1 is hinged to the box cover 2 and secured with a buckle. The jamming gun 3 is placed inside the placement box 1. The box cover 2 is equipped with a stretchable support assembly. When transporting the jamming gun 3, all components except the support assembly are placed inside the placement box 1. When using the jamming gun 3, the support assembly unfolds and supports the fixing plate 9. The lower end of the connecting rod 10 passes through the fixing plate 9 and is threadedly connected to the threaded cover 11. The top of the connecting rod 10 is ball-jointed to the base 12. The base 12 is slidably connected to two pressing blocks 14. The base 12 is rotatably connected to the adjusting screw 13, which is threadedly connected to the pressing blocks 14. The jamming gun 3 is placed on the base 12, and the two pressing blocks 14 clamp the jamming gun 3.

[0025] As shown in Figures 2, 4, and 7, the support assembly includes a first support rod 4, a locking block 401, a second support rod 5, a locking hole 6, a first return spring 7, a locking rod 8, and a pop-out assembly. One end of the first support rod 4 is rotatably connected to the lid 2, and the other end of the first support rod 4 is slidably connected to the locking rod 8. The first return spring 7 is sleeved on the locking rod 8, with one end connected to the locking rod 8 and the other end connected to the first support rod 4. The second support rod 5 is slidably connected inside the first support rod 4. The second support rod 5 has a locking hole 6, and the end of the locking rod 8 is limited to the locking hole 6. The top of the second support rod 5 together supports the fixing plate 9. The top of the lid 2 is rotatably connected to the locking block 401. The locking block 401 on the top of the lid 2 locks the folded state of the first support rod 4 through a buckle structure to prevent accidental unfolding during transportation. A pop-out assembly for ejecting the first support rod 4 is provided in the middle of the lid 2.

[0026] As shown in Figure 7, the pop-out assembly includes a top plate 16 and a second return spring 17. A sliding groove 15 is opened inside the box cover 2. The top plate 16 is slidably connected to the sliding groove 15, and the top surface of the top plate 16 is in contact with the first support rod 4. The second return spring 17 is provided inside the box cover 2. One end of the second return spring 17 is connected to the top plate 16, and the other end is connected to the inside of the box cover 2.

[0027] As shown in Figure 7, it also includes a fastening pad 18. The end of the second support rod 5 connected to the fixing plate 9 is provided with a fastening pad 18. The fastening pad 18 and the fixing plate 9 are pressed together to form a buffer between the second support rod 5 and the fixing plate 9, reducing the impact of mechanical vibration on aiming accuracy.

[0028] As shown in Figure 6, it also includes an auxiliary plate 19. The auxiliary plate 19 is snapped onto both sides of the base 12. The auxiliary plate 19 extends the support length and optimizes the stability of the base 12 supporting the interference gun 3.

[0029] As shown in Figure 6, it also includes a protective pad 20. The protective pad 20 is connected to the adjacent side of the two extrusion blocks 14 to prevent the extrusion blocks 14 from scratching the outer shell of the interference gun 3 when clamping.

[0030] As shown in Figure 6, it also includes a rubber sleeve 21. The end of the adjusting screw 13 is fitted with a rubber sleeve 21, which not only improves the operating feel but also prevents metal parts from being damaged by bumps.

[0031] To prevent drone filming or disruption of order, staff transported the placement box 1 to the center of the no-fly zone. They then opened the box lid 2, removed all components from the box 1, and closed the lid, ensuring the box 1 was stable. Next, they rotated the locking block 401, disengaging it from the first support rod 4. The compressed second return spring 17 then rebounded, lifting the first support rod 4 via the top plate 16, facilitating its rotation. After the four first support rods 4 were extended to a vertical position, staff manually pulled the second support rod 5 upwards, causing it to slide out of the first support rod 4. At this point, the locking rod 8, under the force of the first return spring 7, pressed tightly against the second support rod 5. When the locking hole 6 of the second support rod 5 aligned with the locking rod 8, the first return spring 7 rebounded, pushing the locking rod 8 into the locking hole 6 of the second support rod 5, automatically limiting its position. Finally, the fixing plate 9 was placed over the four second support rods 5, and the second support rod 5 was lifted... The fastening pad 18 of the part can increase the stability of the connection between the fixing plate 9 and the fixing plate 9, thereby ensuring that the fixing plate 9 will not fall off or shake. The threaded end of the connecting rod 10 is passed through the fixing plate 9 and fixed by the threaded cover 11 to complete the installation of the connecting rod 10. Then, the two auxiliary plates 19 are snapped on, the jamming gun 3 is placed on the base 12, and the adjusting screw 13 is rotated to reverse the threads on both sides of the adjusting screw 13, thereby bringing the two pressing blocks 14 closer to each other and clamping the jamming gun 3. The rubber sleeve 21 at the end of the adjusting screw 13 provides a non-slip grip surface. The protective pad 20 is made of high friction silicone material to avoid scratching the shell when clamping the jamming gun 3. The ball hinge structure allows the base 12 to be adjusted in multiple directions. The operator can manually adjust the pitch and horizontal angle of the jamming gun 3, so that the jamming gun 3 can cover targets in the air at multiple angles. The operator switches the jamming mode according to the UAV frequency band. The equipment blocks the UAV communication link by directionally emitting electromagnetic signals.

[0032] Select a suitable frequency to interfere with the intruding drone. After the time limit is over, loosen the adjusting screw 13 in sequence, remove the jamming gun 3, disassemble the auxiliary plate 19, unscrew the threaded cover 11, remove the connecting rod 10, pull out the fixing plate 9, pull the locking rod 8, compress the first return spring 7, and the second support rod 5 falls freely. Release the locking rod 8, and the end of the locking rod 8 abuts against the second support rod 5. Rotate the first support rod 4. After the first support rod 4 is pressed against the top plate 16, push the top plate 16 to slide down along the slide groove 15, compress the second return spring 17, and after the first support rod 4 is flush with the top surface of the box cover 2, rotate the locking block 401 to prevent the first support rod 4 from popping out. Open the box cover 2, place the disassembled parts in the placement box 1 according to the predetermined position, and finally fix the box cover 2 with the buckle.
