Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) jamming technology, and in particular to a modular, omnidirectional, interchangeable jamming device with distributed heat dissipation. Background Technology

[0002] In recent years, with the rapid popularization of drone technology, while bringing convenience, it has also given rise to increasingly serious security risks, such as drones illegally entering no-fly zones, infringing on privacy, and even carrying dangerous items. To address these threats, drone jamming equipment has emerged as an important defensive measure against drones.

[0003] As the demands for countermeasures against drones continue to evolve—for example, the need to counter new, multi-band drones, improve effective jamming range and suppression capabilities, and adapt to different application scenarios—drone jamming equipment is developing towards full-band coverage, high-power output, and omnidirectional dual jamming capabilities. Full-band coverage means that the equipment needs to integrate multiple power amplifier modules operating in different frequency bands. Achieving dual jamming capabilities and high-power output significantly increases the number and power of the electronic components in the jamming equipment, resulting in a dramatic increase in heat generation and a substantial improvement in the equipment's thermal density.

[0004] Existing drone jamming equipment typically places its heat-generating components centrally within the chassis or adjacent to a single chassis wall. Cooling methods mostly rely on forced airflow cooling via fans on a single side or two opposite sides of the chassis. This design, with its relatively concentrated heat source and limited heat dissipation surface, leads to excessive heat load in localized areas and poor overall cooling performance. During prolonged operation of jamming equipment with full-band coverage and high power output, this can easily cause localized overheating and trigger a shutdown protection mechanism, affecting the equipment's continuous operational capability.

The directional antenna assembly also has a sealed antenna housing.

[0016] In one embodiment, the heat dissipation duct includes an irregularly shaped heat sink and a cover plate. One end of the irregularly shaped heat sink is provided with a fan mounting position. The irregularly shaped heat sink is provided with a highly constricted section. The cover plate is detachably connected to the outside of the irregularly shaped heat sink.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] This invention completely overcomes the shortcomings of traditional interference devices, which suffer from concentrated heat sources and limited heat dissipation surfaces, by distributing multiple heat-generating elements on at least three different surfaces inside the casing and simultaneously setting multiple heat dissipation structures at corresponding positions on the outside of the casing. This multi-faceted distributed heat dissipation design effectively disperses the heat source density, significantly increases the heat dissipation surface area, and allows heat to be dissipated simultaneously and efficiently from multiple directions of the interference device. This significantly reduces the temperature inside the interference device, especially in key heat-generating areas, solves the problem of localized overheating, and improves the continuous working capability of the interference device. Furthermore, this invention optimizes the structure of the heat dissipation duct by including at least one converging section within the duct that reduces its cross-sectional area. This accelerates the airflow velocity through key areas of the heat dissipation duct, further enhancing the heat dissipation efficiency of the high-power modules corresponding to the duct.

[0022] The core advantage of this utility model lies in its innovative comprehensive heat dissipation solution of "distributed heat source arrangement + multi-faceted collaborative heat dissipation + optimized air duct structure".

It significantly improves the continuous working capability, stability and service life of the jamming equipment, while providing a good heat dissipation foundation for the compact and modular design of jamming equipment.

[0049] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0050] This invention provides a modular, omnidirectional, interchangeable jamming device with distributed heat dissipation to solve the problem of localized overheating in existing jamming devices and improve their continuous operating capability. Please refer to [link to relevant documentation]. Figures 1-14 .

[0051] A modular, omnidirectional, interchangeable jamming device with distributed heat dissipation includes a jamming host 3 with distributed heat dissipation. The jamming host 3 includes a housing, multiple heat-generating elements, and multiple heat dissipation structures. Figure 1 and Figure 2As shown, the jamming host 3 adopts a six-sided enclosed shell structure. This enclosed shell structure protects the internal electronic components from dust and water, facilitating stable operation during long-term outdoor use. Multiple heat-generating components are housed inside the shell, such as the power module 3-1 and multiple power amplifier modules 3-6 covering the entire frequency band. These heat-generating components are distributed across at least three different surfaces inside the shell, such as the rear, left, and right sides, ensuring uniform heat distribution. Corresponding to the outer position of each heat-generating component, distributed heat dissipation structures are provided, including a bottom wall heat dissipation structure 3-13 and a side wall heat dissipation structure 3-14. Specifically, as shown... Figure 1 and Figure 2 As shown, the bottom wall of the casing is provided with a bottom wall heat dissipation structure 3-13, the left and right side walls of the casing are provided with side wall heat dissipation structures 3-14, and the rear wall of the casing is also provided with a heat dissipation fin structure 3-16, thus achieving distributed heat dissipation on the four surfaces of the casing: bottom, left, right, and rear. Figure 3 As shown, the sidewall heat dissipation structure 3-14 includes a fan 3-14-2 and a heat dissipation duct. The fan 3-14-2 is located at one end of the heat dissipation duct. The flow channel inside the heat dissipation duct body has at least one converging section in the airflow direction that reduces the cross-sectional area of ​​the flow channel. Specifically, the heat dissipation duct includes a shaped heat sink 3-14-1 and a cover plate 3-14-3. One end of the shaped heat sink 3-14-1 has a fan mounting position. The shaped heat sink 3-14-1 has a highly converging section. The cover plate 3-14-3 is detachably connected to the outside of the shaped heat sink 3-14-1. The cover plate 3-14-3 and the shaped heat sink 3-14-1 cooperate to form several flow channels. The fan 3-14-2 is located at the air inlet end of the heat dissipation duct, driving external air into the flow channel. By designing the flow channel to include at least one converging section that reduces the cross-sectional area of ​​the flow channel, the airflow speed through the key area of ​​the heat dissipation duct can be accelerated, further improving the heat dissipation efficiency of the high-power module corresponding to the heat dissipation duct. Preferably, the airflow of the cooling duct is directed upwards, and several fans 3-14-2 are installed at one end of the cooling duct. For clarity, here... Figure 3 The cover plate 3-14-3 has a transparent structure; however, in actual use, the cover plate 3-14-3 does not need to be made of transparent material. The cover plate 3-14-3 is fixed to the irregularly shaped heat sink 3-14-1 with bolts. By setting the irregularly shaped heat sink 3-14-1 and its corresponding cover plate 3-14-3, a convergent flow channel is formed, which can reduce the overall mass and further improve the cooling effect.

[0052] In this embodiment, as Figure 4As shown, the multiple heat-generating components include a power supply module 3-1 and multiple power amplifier modules 3-6. These components are the primary heat-generating elements in the interference host 3. The power supply module 3-1 converts AC power to DC power and is positioned flush against the inner rear wall of the casing. It is electrically connected to and supplies power to the multiple power amplifier modules 3-6, which are respectively located on the bottom and left / right side walls of the inner casing. Specifically, as shown... Figure 3 As shown, there are seven power amplifier modules 3-6, each corresponding to a different interference frequency. Their power outputs vary. The two most powerful power amplifier modules 3-6 are located on the left and right side walls of the chassis, respectively, with corresponding side wall heat dissipation structures 3-14 on the outer side of these side walls. The remaining five power amplifier modules 3-6 are located on the bottom wall of the chassis, with corresponding bottom wall heat dissipation structures 3-13 on the outer side of this bottom wall. The least powerful power amplifier module 3-6 is located in the middle of the bottom wall of the chassis. Figure 5 As shown, the bottom wall heat dissipation structure 3-13 includes a natural ventilation structure 3-13-1 located in the middle of the bottom wall of the housing and mechanical ventilation structures 3-13-2 located on both sides of the natural ventilation structure 3-13-1. The natural ventilation structure 3-13-1 includes several connecting plates connecting the housing and the tripod 1 / servo gimbal 2 and ventilation slots located between two adjacent connecting plates. The mechanical ventilation structure 3-13-2 includes heat sinks and several bottom cooling fans located at one end of the heat sinks. A minimum power amplifier module 3-6 is located on the inner side of the middle of the bottom wall of the housing, and the natural ventilation structure 3-13-1 is located on the outer side. This achieves effective heat dissipation while reducing the overall weight, and also facilitates the connection and installation between the main unit 3 and the tripod 1 / servo gimbal 2 below.

[0053] The jamming host 3 also contains other heat-generating components that generate relatively less heat compared to the power supply module 3-1 and the power amplifier module 3-6, such as Figures 5-7 As shown, the system includes an interference source module 3-2, a network switching module 3-4, and a positioning and orientation module 3-15. The interference source module 3-2 includes an interference board 3-2-1 and a decoy board 3-2-2. The interference source module 3-2 and network switching module 3-4 are mounted on a module mounting plate 3-3, which is positioned above the power amplifier module 3-6 on the bottom wall. The positioning and orientation module 3-15 is located below the top wall of the housing. A power supply module 3-1 is electrically connected to the interference source module 3-2, network switching module 3-4, and positioning and orientation module 3-15. The interference source module 3-2 is electrically connected to the network switching module 3-4, positioning and orientation module 3-15, and multiple power amplifier modules 3-6. The interference source module 3-2 is used to generate interference signals. The decoy board 3-2-2 in the interference source module 3-2 is used to generate false GPS (Global Positioning System) positioning information to be sent to the drone, such as... Figure 10 As shown, the jamming host 3 has a GNSS (Global Navigation Satellite System) antenna 7 on its top. A decoy board 3-2-2 is electrically connected to a power amplifier module 3-6, and the power amplifier module 3-6 is electrically connected to the GNSS antenna 7. By adding a decoy board 3-2-2 inside the jamming source module 3-2, the jamming device can simultaneously possess a decoy function.

[0054] like Figure 2 As shown, the rear sidewall of the housing has an outwardly protruding structure. The power module 3-1 is located in the inner recess of the outwardly protruding structure. Multiple heat dissipation structures also include heat dissipation fins 3-16, which are located on the outer side of the outwardly protruding structure. By designing an outwardly protruding structure on the rear sidewall of the housing, the power module 3-1 is positioned relatively far from other heat-generating components inside the housing, and the heat dissipation area of ​​the rear sidewall is increased. Furthermore, the heat dissipation effect of the power module 3-1 is further improved by the outwardly protruding structure and the heat dissipation fins 3-16 located on its outer side.

[0055] like Figure 2 As shown, the rear sidewall of the housing is detachably connected to its adjacent housing wall, and the two are connected by screws; as Figure 6 As shown, the casing also has an external DC power interface 3-7, which electrically connects to the interference source module 3-2, the network switching module 3-4, the positioning and orientation module 3-15, and multiple power amplifier modules 3-6. By making the rear sidewall a removable structure, the rear sidewall of the casing and the power module 3-1 mounted on it can be removed, further reducing interference with the heat-generating components inside the host unit 3. The removed rear sidewall can be used for, for example... Figure 1 The front sidewall of the device is replaced with a sealing plate to enclose the casing. After removing the power module 3-1, DC power can be directly supplied to the various modules inside the interference host 3 through the external DC power interface 3-7, thereby reducing the heat generated by the power module 3-1 inside the original casing.

[0056] The modular, omnidirectional, and interchangeable jamming device with distributed heat dissipation provided in this embodiment includes the following components: tripod 1, servo gimbal 2, jamming host 3, omnidirectional antenna assembly 4, directional antenna assembly 5, and directional receiving antenna 6; by replacing different components, an omnidirectional jamming configuration can be formed (e.g., ...). Figure 1 , Figure 2 (as shown) or directional interference patterns (such as...) Figure 8 (as shown) or composite interference patterns (i.e., omnidirectional and directional dual interference patterns, such as...) Figure 9 (As shown).

[0057] By combining the above components in different ways, the jamming device can have the following assembly forms, thus forming multiple operating modes:

[0058] Omnidirectional interference patterns: such as Figure 1 and Figure 2 As shown, the jamming device includes a tripod 1, a jamming host 3, and an omnidirectional antenna assembly 4. The top of the tripod 1 is detachably connected to the jamming host 3, and the omnidirectional antenna assembly 4 is detachably connected to the top of the jamming host 3 and electrically connected to multiple power amplifier modules 3-6 of the jamming host 3. At this time, the servo pan-tilt unit 2, the directional antenna assembly 5, and the directional receiving antenna 6 are omitted and do not need to be installed, thus forming an omnidirectional jamming mode for the jamming device.

[0059] Directional interference patterns: such as Figure 8 As shown, the jamming device includes a tripod 1, a servo gimbal 2, a jamming host 3, a directional antenna assembly 5, and a directional receiving antenna 6. The top of the tripod 1 is detachably connected to the servo gimbal 2, and the top of the servo gimbal 2 is detachably connected to the jamming host 3. The directional antenna assembly 5 is detachably connected to the front of the jamming host 3 and electrically connected to multiple power amplifier modules 3-6 of the jamming host 3. The directional receiving antenna 6 is detachably connected to the left and right sides of the jamming host 3 and electrically connected to the positioning and orientation modules 3-15 of the jamming host 3. At this time, the omnidirectional antenna assembly 4 is omitted and does not need to be installed, thus forming a directional jamming mode for the jamming device.

[0060] Composite interference morphology: such as Figure 9 As shown, based on the directional jamming configuration, the omnidirectional antenna assembly 4 is detachably connected to the top of the jamming host 3. The jamming host 3 also includes a power divider 3-5, with multiple power amplifier modules 3-6 electrically connected to the power divider 3-5. The power divider 3-5 is electrically connected to the omnidirectional antenna assembly 4 and the directional antenna assembly 5, enabling rapid switching between omnidirectional and directional jamming functions. Alternatively, multiple power amplifier modules 3-6 can be distributed to the omnidirectional antenna assembly 4 and the directional antenna assembly 5 respectively, achieving a combined jamming function that simultaneously performs omnidirectional and directional jamming, forming a combined jamming mode for the jamming equipment.

[0061] like Figure 6 and Figure 11 As shown, the jamming host 3 is equipped with an external DC power interface 3-7, a network interface 3-8, a directional antenna mounting interface 3-9, an omnidirectional antenna mounting interface 3-10, and a directional receiving antenna signal interface 3-11; the power divider 3-5 is electrically connected to the directional antenna mounting interface 3-9 and / or the omnidirectional antenna mounting interface 3-10; the positioning and directional module 3-15 is electrically connected to the directional receiving antenna signal interface 3-11; the network interface 3-8 is electrically connected to the network switching module 3-4; and the power module 3-1 is equipped with an AC input interface. Figure 6As shown, the jamming host 3 has a quick-connect interface 3-12 that connects to the power module 3-1. The quick-connect interface 3-12 electrically connects to the jamming source module 3-2, the positioning and orientation module 3-15, the network switching module 3-4, and multiple power amplifier modules 3-6. The servo pan / tilt unit 2 is equipped with an azimuth motor and a pitch motor, which can adjust the rotation and pitch angles of the jamming host 3, such as... Figure 6 As shown, the servo gimbal 2 is equipped with an external power interface 2-1, an external network interface 2-2, a power output port 2-3, and a network transmission interface 2-4; when the interference device is assembled with the servo gimbal 2, such as Figure 10 As shown, the AC input interface of the power module 3-1 is connected to the power output port 2-3 of the servo gimbal 2 via power connection cable 3-1-1. The network interface 3-8 of the interference host 3 is connected to the network transmission interface 2-4 of the servo gimbal 2 via network connection cable 3-1-2. The network interface 3-8 of the interference host 3 can also be located on the rear side wall of the housing. Figure 10 As shown, by setting the servo gimbal 2, the jamming host 3 can rotate 360 ​​degrees horizontally multiple times on the tripod 1 without affecting power supply and network signal transmission. An external power supply can also simultaneously power the servo gimbal 2 and the jamming host 3.

[0062] like Figure 8 and Figure 9 As shown, when the jamming device is in directional jamming mode or composite jamming mode, the jamming device also includes a directional antenna assembly 5. Figure 6 , Figure 10 and Figure 11 As shown, the directional antenna assembly 5 is detachably connected to the front side of the housing. During installation, the front panel of the housing must first be removed. Then, the directional antenna assembly 5 and the jamming host 3 are connected through the directional antenna mounting interface 3-9. Finally, the directional antenna assembly 5 is connected and fixed to the housing through the mounting connecting plate 5-1. Figure 6 and Figure 7 The directional antenna mounting interface 3-9 shown is a blind-mating electrical connector, meaning that the directional antenna assembly 5 and the power divider 3-5 of the jamming host 3 are electrically connected via a blind-mating electrical connector. For example... Figure 12As shown, the directional antenna assembly 5 has an antenna mounting plate 5-2 at its connection surface with the housing. The antenna mounting plate 5-2 has a hollow structure and an internal circulation cooling fan 5-6 is mounted on it. The internal circulation cooling fan 5-6 faces the interference source module 3-2. By setting the internal circulation cooling fan 5-6 and making the antenna mounting plate 5-2 a hollow structure with the internal circulation cooling fan 5-6 facing the interference source module 3-2, the internal circulation cooling fan 5-6 can form a circulating airflow in the internal space of the directional antenna assembly 5 and the housing, which helps to dissipate heat from the various heat-generating components inside the directional antenna assembly 5 and the housing. The antenna mounting plate 5-2 is equipped with multiple directional antennas, including at least one of a log-periodic antenna 5-3, a horn antenna 5-4, and a helical antenna 5-5. The directional antenna assembly 5 also has a sealed antenna housing. Specifically, in this implementation, there are four log-periodic antennas 5-3, two horn antennas 5-4, one helical antenna 5-5, and seven directional antennas set to different interference frequencies and connected to seven corresponding power amplifier modules 3-6, achieving full-band coverage against UAV interference. For example... Figure 10 and Figure 11 As shown, the directional receiving antenna 6 is set on the left and right sides of the jamming host 3. The directional receiving antenna 6 has a foldable structure and is equipped with a hinged rotating rod and a sliding rod. The rotating rod is provided with a groove that matches the sliding rod. The end of the rotating rod is provided with an antenna head. The antenna head is connected to the directional receiving antenna signal interface 3-11 through a wire. This maximizes the distance between the antenna heads of the directional receiving antenna 6 installed on the left and right sides of the jamming host 3 when the directional receiving antenna 6 is unfolded, which meets the requirements of the usage specifications of the directional receiving antenna 6.

[0063] The working principles of the omnidirectional jamming mode and the directional jamming mode of the jamming device are as follows: Figure 13 and Figure 14As shown, after an external device (such as radar or signal detection equipment) detects a UAV target, it sends the information to the command and control terminal. The control terminal sends interference control signal command data to the network switching module 3-4 through the display and control software, which is then transmitted to the interference source module 3-2. After receiving the command, the interference source module 3-2 generates a corresponding interference signal based on the interference information and sends it to the power amplifier module 3-6. The power amplifier module 3-6 amplifies the interference signal and outputs it to the antenna assembly to radiate electromagnetic waves. In omnidirectional interference mode, the power amplifier module 3-6 outputs to the omnidirectional antenna assembly 4, and in directional interference mode, the power amplifier outputs to the directional antenna assembly 5, effectively interfering with the target. Regardless of whether it is omnidirectional or directional interference mode, the positioning function of the positioning and directional module 3-15 is required. In directional interference mode, the directional function of the positioning and directional module 3-15 is also required, and a directional receiving antenna 6 needs to be installed to work with the positioning and directional module 3-15. In directional interference mode, the servo gimbal 2 is equipped with azimuth and pitch motors, enabling azimuth and pitch adjustment. It communicates with the interference source module 3-2 via a serial port. The interference source module 3-2 forwards commands from the host computer to the servo gimbal 2, which adjusts the azimuth and pitch motors to the commanded positions and reports the real-time azimuth and pitch angles to the control and display software via a bus. The power supply module 3-1 of the interference device converts 220V AC to DC power. The interference source module 3-2 collects self-test information from each module and reports the voltage, current, temperature, and operating status of each module to the terminal software in real time via the network exchange module 3-4, forming a BIT (Built-In Test) test, which allows for real-time acquisition of the overall machine's operating status.

[0064] In summary, this invention completely overcomes the shortcomings of traditional interference devices, which suffer from concentrated heat sources and limited heat dissipation surfaces, by distributing multiple heat-generating elements on at least three different surfaces inside the casing and simultaneously setting multiple heat dissipation structures at corresponding positions on the outside of the casing. This multi-faceted distributed heat dissipation design effectively disperses the heat source density, significantly increases the heat dissipation surface area, and allows heat to be dissipated simultaneously and efficiently from multiple directions of the interference device. This significantly reduces the temperature inside the interference device, especially in key heat-generating areas, solves the problem of localized overheating, and improves the continuous working capability of the interference device. Furthermore, this invention optimizes the structure of the heat dissipation duct by designing at least one converging section within the duct that reduces its cross-sectional area. This accelerates the airflow velocity through key areas of the heat dissipation duct, further enhancing the heat dissipation efficiency of the high-power modules corresponding to the duct.

[0065] This invention also achieves flexible combination and interchangeability of core functional modules such as the omnidirectional antenna assembly 4, directional antenna assembly 5, directional receiving antenna 6, and servo gimbal 2 through a highly modular design of the jamming device. Users can easily switch between three working modes—omnidirectional jamming, directional jamming, and composite jamming (directional + omnidirectional)—simply by quickly replacing or combining the corresponding modules according to the actual application scenario requirements. This "one device, multiple uses" design significantly improves the applicability of the equipment, effectively solves the problem of repeatedly purchasing traditional single-function equipment in different scenarios, and reduces the overall purchase cost. The modules adopt a detachable connection method, with a clear structure and convenient assembly, which not only facilitates rapid on-site deployment and working mode switching, but also significantly reduces the difficulty and cost of equipment maintenance, and provides a good foundation for subsequent functional expansion and technical upgrades.

[0066] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
