Technical Field
[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) jamming technology, and in particular relates to an electronic information jammer for UAVs. Background Technology
[0002] Drone jammers use electronic information technology to drive away or force down intruding drones by emitting jamming signals. Because drones have a large flight range and move quickly, portable drone jammers are often used to facilitate quick and easy jamming, with backpack-style drone jammers being the most common.
[0003] However, existing technologies have some problems: existing backpack-type drone jammers often require a relatively long transmitting antenna to be threaded onto the radio frequency module in the backpack, which increases inconvenience for the operator during travel. Moreover, in order to stabilize the transmitted signal, a wrench is needed to tighten the transmitting antenna very tightly, making disassembling the transmitting antenna time-consuming and laborious. In order to conveniently and flexibly adjust the extension length of the transmitting antenna without disassembling it, we propose a drone electronic information jammer. Utility Model Content
[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a drone electronic information jammer. By driving a worm gear to rotate through a drive motor, the radio frequency module and transmitting antenna move up and down through the rotation of a lead screw driven by the worm gear. This not only saves manpower but also improves the equipment flexibility of the drone jammer.
[0005] This invention is implemented as follows: a drone electronic information jammer has a cavity in the middle of its main body. An radio frequency (RF) module is disposed within the cavity and slidably connected to the interior of the jammer main body. Lead screws are threaded to both sides of the RF module, with the top ends of the lead screws rotatably connected to the jammer main body. A worm gear is fixedly connected to the bottom end of the lead screws and rotatably connected to the jammer main body. Two sets of gears are disposed between the two sets of worm gears, meshing with the worm gears. A second rotating shaft is fixedly connected to the center of the gears, with both ends of the second rotating shaft rotatably connected to the jammer main body. A first rotating shaft is disposed between the two sets of second rotating shafts. A drive motor is disposed at one end of the first rotating shaft, fixedly connected to the output shaft of the drive motor, and the other end of the first rotating shaft rotatably connected to the jammer main body.
[0006] Optionally, a transmitting antenna is threadedly connected to the top of the radio frequency module, and a hole is opened at the top of the jammer body, through which the transmitting antenna passes.
[0007] Optionally, a transmission belt is provided on both sides of the first rotating shaft, and the first rotating shaft and the second rotating shaft are connected by the transmission belt.
[0008] Optionally, two sets of slide rails are fixedly connected to each side of the radio frequency module, and a limit ring is provided between the two sets of slide rails on the same side. The limit ring is fixedly connected to the radio frequency module.
[0009] Optionally, the limiting ring has internal threads, and the lead screw is connected to the inside of the limiting ring via threads.
[0010] Optionally, a limiting groove is provided inside the main body of the jammer near the slide rail, and the limiting groove is slidably connected to the slide rail.
[0011] Optionally, a partition is provided between the gear and the radio frequency module, and the partition is fixedly connected to the limiting groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. By driving the lead screw and worm gear through the drive motor, the radio frequency module and transmitting antenna can move up and down through the lead screw under the drive of the worm gear, which not only saves manpower, but also improves the equipment flexibility of the drone jammer.

[0022] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0023] like Figures 1 to 6 As shown in the figure, this utility model provides an electronic information jammer for unmanned aerial vehicles (UAVs), including a jammer body 1. A cavity 13 is formed in the middle of the jammer body 1, and a radio frequency (RF) module 3 is disposed within the cavity 13. The RF module 3 is slidably connected to the interior of the jammer body 1. Lead screws 6 are threaded to both sides of the RF module 3. The top end of the lead screw 6 is rotatably connected to the jammer body 1, and a worm gear 10 is fixedly connected to the bottom end of the lead screw 6. The bottom end of the worm gear 10 is rotatably connected to the jammer body 1. Two sets of gears 9 are disposed between the two sets of worm gears 10. Gear 9 meshes with worm gear 10. A second rotating shaft 8 is fixedly connected to the center of gear 9. Both ends of the second rotating shaft 8 are rotatably connected to the main body 1 of the jammer. A first rotating shaft 14 is set between the two sets of second rotating shafts 8. A drive motor 12 is set at one end of the first rotating shaft 14. One end of the first rotating shaft 14 is fixedly connected to the output shaft of the drive motor 12. The other end of the first rotating shaft 14 is rotatably connected to the main body 1 of the jammer. A transmission belt 11 is set on both sides of the first rotating shaft 14. The first rotating shaft 14 and the second rotating shaft 8 are connected by transmission belt 11.
[0024] like Figures 1 to 3 As shown, the drive motor 12 drives the first rotating shaft 14 to rotate, and the first rotating shaft 14 drives the second rotating shaft 8 to rotate through the transmission belt 11. Under the drive of the second rotating shaft 8, the gear 9 drives the worm gear 10 to rotate, thereby driving the lead screw 6 to rotate. The radio frequency module 3 moves up and down through the rotation of the lead screw 6.
[0025] Furthermore, a transmitting antenna 2 is threadedly connected to the top of the radio frequency module 3, and a hole is opened at the top of the jammer body 1, through which the transmitting antenna 2 passes.
[0026] like Figures 1 to 3 As shown, the transmitting antenna 2 is generally connected to the female or male connector on the RF module 3 via an N-type connector through a threaded connection. In order to ensure stable signal transmission, the user will usually tighten it with a torque wrench or other tools.
[0027] Furthermore, two sets of slide rails 5 are fixedly connected to each side of the radio frequency module 3, and a limit ring 4 is set between the two sets of slide rails 5 on the same side. The limit ring 4 is fixedly connected to the radio frequency module 3. The limit ring 4 has a thread inside, and the lead screw 6 is connected to the inside of the limit ring 4 through the thread.
[0028] like Figures 4 to 5 As shown, the lead screw 6 and the limiting ring 4 are connected by a thread. The RF module 3 can be moved up and down by the relative rotation between the lead screw 6 and the limiting ring 4.
[0029] Furthermore, a limiting groove 7 is provided inside the main body 1 near the slide rail 5, and the limiting groove 7 is slidably connected to the slide rail 5.
[0030] like Figures 2 to 3 As shown, the slide rail 5 and the limiting groove 7 are matched to each other, ensuring that the radio frequency module 3 moves smoothly up and down.
[0031] Furthermore, a partition 15 is provided between the gear 9 and the radio frequency module 3, and the partition 15 is fixedly connected to the limiting groove 7.
[0032] like Figure 3 As shown, a partition 15 is fixedly connected to the limiting groove 7. The partition 15 is placed between the radio frequency module 3 and the lower transmission module, and plays a role in protecting the lower transmission module.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
