Description

Technical Field

[0001] This utility model relates to the field of electronic interference technology, specifically to a counter-interference device. Background Technology

[0002] Counter-jamming equipment is a device used to counter various types of interference signals and ensure the stable operation of normal communication, navigation and other systems. It can also be used to counter illegal interference sources. Common examples include anti-jamming equipment for drones and anti-jamming equipment for radar.

[0003] Currently, most anti-jamming devices on the market use 360-degree omnidirectional jamming. While this omnidirectional jamming method can interfere with surrounding signals to a certain extent, it has many drawbacks:

[0004] 1. Omnidirectional jamming emits interference signals in directions where interference is not needed, wasting energy and potentially causing unnecessary interference to surrounding electronic equipment and communication systems, affecting their normal operation. For example, in certain security scenarios, it may be necessary to interfere with potential interference sources in a specific direction, while omnidirectional jamming could affect nearby residents' communications, public transportation signals, etc.

[0005] 2. Omnidirectional jamming lacks specificity and cannot concentrate energy to effectively jam targets in a specific direction, resulting in poor jamming effect. Utility Model Content

[0006] The purpose of this invention is to provide a counter-interference device to address the shortcomings of existing technologies. It can precisely interfere in a specific direction, reduce interference to unnecessary surrounding areas, and improve interference efficiency and effectiveness.

[0007] This utility model provides a counter-jamming device, including a main body of the counter-jamming device. Multiple sets of directional jamming structures are provided on the outside of the main body of the counter-jamming device. Adjacent sets of directional jamming structures are connected by connecting components to facilitate the installation of directional jamming structures.

[0008] Each directional interference structure includes a signal blocking reflector. The connecting assembly includes two external plug-in plates that are rotatably connected. The two ends of the signal blocking reflector are respectively inserted into the two external plug-in plates, which facilitates adjusting the angle of the directional interference structure to adjust the directional anti-interference range.

[0009] In the anti-interference device described above, preferably, T-shaped plugs are fixed on both sides of the signal blocking reflector, and T-shaped slots are opened inside the two external plug plates of the connecting assembly. Each T-shaped plug is inserted into each T-shaped slot, which facilitates the splicing of multiple sets of directional interference structures to expand the anti-interference range.

[0010] Preferably, the two external plug plates of the connecting assembly each have a plug slot on their opposite sides, the plug slot is connected to the T-shaped slot, and the two ends of the signal blocking reflector are respectively plugged into the two T-shaped slots.

[0011] Preferably, in the connection assembly, one of the external plug-in plates has two vertically distributed connecting blocks fixed on one side, and the other T-shaped slot has a connecting plate fixed on one side. A damping shaft is fixed on the side of the connecting plate near the connecting blocks. The damping shaft is located between the two connecting blocks and is rotatably connected to the connecting blocks, which facilitates adjusting the angle of the signal blocking reflector to adjust the directional anti-interference range.

[0012] The principle of a damping hinge is to use the friction generated by the compression between the pads to keep the screen in its current position. For example, a laptop hinge requires a certain amount of force when opening the laptop screen, but this force does not need to be very large. When the opening stops, the screen will not wobble or fall off, but will be kept in the desired position by the friction on the hinge.

[0013] Preferably, two flexible signal blocking components are fixed between the two external plug-in plates in the connection assembly, and the connecting block, connecting plate and damping shaft are all disposed between the two flexible signal blocking components. The flexible signal blocking components can be made of conductive foam.

[0014] Preferably, the signal blocking reflector, T-shaped plug and external plug plate are made of the same material. The signal blocking reflector, T-shaped plug and external plug plate are all made of metal materials with high conductivity, such as copper and aluminum, and their surfaces are specially treated to improve the reflectivity.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Precise jamming: This invention can accurately jam targets in a specific direction, improving the accuracy of jamming; compared with omnidirectional jamming, it can more effectively suppress potential jamming sources and ensure the normal operation of electronic equipment and communication systems in the target area.

[0017] 2. Reduce interference range: The interference signal in the opposite direction of the signal blocking reflector is effectively reflected and blocked, which greatly reduces the interference to unnecessary surrounding areas. This not only reduces the impact on other normal electronic equipment and communication systems, but also avoids legal and regulatory issues caused by excessive interference range.

[0018] 3. Improve energy utilization efficiency: This invention enables the interference signal to be concentrated in the direction of the desired interference, avoiding energy dispersion and waste, improving the energy utilization efficiency of the interference device, extending the device's battery life or reducing the device's energy consumption.

[0019] 4. Wide range of applications: This utility model can install multiple sets of directional interference structures as needed and adjust the angle of each set of directional interference structures, thereby adjusting the directional anti-interference range. Attached Figure Description

[0029] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] Embodiment 1 of this utility model: as follows Figures 1-5 As shown, this utility model provides an anti-jamming device, including an anti-jamming device body 1. The anti-jamming device body 1 includes core components such as an antenna, a signal generator, and a power amplifier. The antenna layout and connection method meet the requirements of directional interference. For example, by using a specially shaped antenna element and antenna array, and based on the principle of electromagnetic radiation, the radiation pattern of the antenna is adjusted to have a high gain in the 120-degree angle direction, thereby accurately guiding the interference signal to the desired interference direction.

[0031] The main body 1 of the anti-jamming device is provided with multiple sets of directional jamming structures 2. Each set of directional jamming structures 2 includes a signal blocking reflector 21. The signal blocking reflector 21 is made of a metal material with high conductivity, such as copper or aluminum, and its surface is specially treated to improve the reflection performance.

[0032] Two adjacent sets of directional interference structures 2 are connected by a connecting component 3. The connecting component 3 includes two external plug-in plates 31. T-shaped plugs 22 are fixed on both sides of the signal blocking reflector 21. T-shaped slots 32 are formed inside the two external plug-in plates 31 of the connecting component 3. A plug-in groove 33 is formed on the side of the two external plug-in plates 31 that is far apart from each other. The plug-in groove 33 communicates with the T-shaped slot 32. The T-shaped plugs 22 on the signal blocking reflector 21 are inserted into the T-shaped slots 32 from top to bottom. At the same time, the side of the signal blocking reflector 21 is inserted into the T-shaped slots 32, which facilitates the splicing of multiple sets of directional interference structures 2.

[0033] Moreover, the signal blocking reflector 21, the T-shaped plug 22 and the external plug plate 31 are made of the same material, which enables the T-shaped plug 22 and the external plug plate 31 to also block and reflect signals.

[0034] When the three sets of directional interference structures are spliced ​​together, as follows: Figure 5 As shown, if the two external connectors 31 of each set of connecting components 3 are at a 120-degree angle, then the two adjacent signal blocking reflectors 21 will also form a 120-degree angle. When the interference signal propagates in the 240-degree direction away from the interference, the signal blocking reflector 21 can effectively reflect the signal back to the 120-degree direction of the directional interference, enhancing the strength of the interference signal in that direction, while preventing the interference signal from leaking into areas where interference is not needed. Compared to omnidirectional interference, this method can more effectively suppress potential interference sources and ensure the normal operation of electronic equipment and communication systems in the target area.

[0035] In addition, the directional interference structure 2 of this utility model includes, but is not limited to, three sets that can be spliced ​​together. When three or more sets of directional interference structures 2 are spliced ​​together, the anti-interference range can be expanded.

[0036] Embodiment 2 of this utility model: as follows Figures 3-4 As shown, in the connecting assembly 3, one of the external plug-in plates 31 has two vertically distributed connecting blocks 34 fixed on one side, and the other T-shaped slot 32 has a connecting plate 35 fixed on one side. The connecting plate 35 has a damping shaft 36 fixed on the side near the connecting block 34. The damping shaft 36 is located between the two connecting blocks 34 and is rotatably connected to the connecting blocks 34.

[0037] Since the angle between the two external connectors 31 is adjustable, it is easy to adjust the angle between the signal blocking reflectors 21, so that this utility model is not limited to the 120-degree directional interference mentioned above, thereby being able to adjust the directional anti-interference range and having a wide range of applications.

[0038] Embodiment 3 of this utility model: as follows Figures 3-4 As shown, two flexible signal blocking components 37 are fixed between the two external plug-in plates 31 in the connecting assembly 3, and the connecting block 34, the connecting plate 35 and the damping shaft 36 are all located between the two flexible signal blocking components 37.

[0039] Among them, the flexible signal blocking component 37 can be made of conductive foam. Conductive foam is a foam material made of conductive materials. It has excellent conductivity and softness, and can effectively absorb and reflect electromagnetic waves to prevent electromagnetic waves from interfering with electronic devices. It has been widely used in electronic devices, communications, automobiles and other fields.

[0040] Electromagnetic shielding essentially forms an electromagnetic barrier through a metal conductor. If two shielding plates are in complete, tight contact without any gaps, the conductor surface is continuous, and electromagnetic waves are reflected or absorbed to the maximum extent. However, because there are gaps between the two adjacent external plug-in plates 31 in this invention due to rotation requirements, this embodiment installs a flexible signal blocking component 37 between the two external plug-in plates 31. This avoids the discontinuity of the conductor surface caused by the gaps, thereby enhancing the signal blocking and reflection capabilities of this invention.
