Description

Technical Field

[0001] This application relates to the field of drone countermeasures technology, specifically to a signal processing component and drone countermeasures equipment. Background Technology

[0002] Drone countermeasures equipment is a defense system used to detect, identify, track, and ultimately disable illegally intruding drones. Drone countermeasures equipment typically includes functional modules corresponding to drone reconnaissance, direction finding, and attack capabilities. In existing drone countermeasures equipment, multiple functional modules are often directly installed inside the same housing, resulting in a large deployment space and the heat generated by multiple functional modules easily accumulating inside the housing, leading to poor heat dissipation performance. Summary of the Invention

[0003] In view of the above problems, this application provides a signal processing component and a drone countermeasure device to solve the problems of large deployment space and poor heat dissipation performance of functional modules in the prior art.

[0004] According to one aspect of the embodiments of this application, a signal processing component is provided, comprising: a mounting frame, which is prismatic in shape, having an air inlet at one end along the axial direction and an air outlet at the other end; a baffle column inserted inside the mounting frame, with a heat dissipation space formed between the outer peripheral sidewall of the baffle column and the mounting frame; a plurality of functional modules, which are circumferentially mounted on the mounting frame, each functional module having a plurality of axially extending heat sinks spaced apart on the side facing the interior of the mounting frame, each heat sink extending into the heat dissipation space, and a heat dissipation channel formed between adjacent heat sinks; and an airflow driving mechanism disposed at at least one end of the mounting frame along the axial direction, for driving airflow through the air inlet and air outlet and through the heat dissipation channel.

[0005] In one alternative approach, the end of the heat sink facing away from the functional module abuts against the side wall of the baffle column.

[0006] In one alternative embodiment, the functional module further includes a baffle plate that covers the ends of multiple heat sinks and abuts against the sidewall of the baffle column.

[0007] In one alternative embodiment, the heat sinks include multiple transition heat sinks located on both sides along the circumference of the mounting frame, with the multiple transition heat sinks gradually increasing in height from both sides towards the middle; in the circumference of the mounting frame, adjacent transition heat sinks on different functional modules abut against each other in a one-to-one correspondence.

[0008] In one alternative configuration, the end of the wind deflector facing the air inlet is tapered.

[0009] In one alternative approach, multiple functional modules are arranged axially on the mounting frame, and the heat generated by the functional modules gradually increases from the end where the air inlet is located to the end where the air outlet is located.

[0010] In one alternative embodiment, mounting covers are respectively provided at both ends of the mounting frame along the axial direction, and an airflow driving mechanism is disposed inside the mounting covers. The mounting covers have ventilation holes on at least one side along the circumferential direction of the mounting frame, and the ventilation holes at both ends of the mounting frame form an air inlet and an air outlet, respectively. The mounting cover at one end of the mounting frame has a first mounting part for fixed connection with the bracket of the UAV countermeasure device. The mounting cover at the other end of the mounting frame has a second mounting part for mounting the antenna assembly of the UAV countermeasure device.

[0011] In one alternative embodiment, in the circumferential direction of the mounting frame, at least one side of the functional module has an interface, and a cable storage space is formed between two adjacent functional modules to accommodate cables between the interfaces connected to the multiple functional modules; the signal processing component also includes a cover plate connected between two adjacent functional modules and covering the cable storage space.

[0012] In one alternative embodiment, the signal processing component also includes a handle located between two adjacent functional modules, the handle extending axially, with its two ends fixedly connected to the mounting frame and its middle position fixedly connected to the cover plate.

[0013] According to another aspect of the embodiments of this application, a drone countermeasure device is provided, which includes the signal processing component described in any one of the above claims.

[0014] This embodiment of the application effectively reduces the footprint and deployment space requirements of the signal processing components by arranging multiple functional modules circumferentially around the mounting frame, thereby improving the integration of the signal processing components. Simultaneously, the internal space of the mounting frame can form an airflow channel. By inserting wind deflectors inside the mounting frame, a heat dissipation space is formed between the mounting frame and the wind deflectors. Furthermore, by setting heat sinks on the functional modules that extend into this heat dissipation space, the airflow entering the mounting frame is diverted by the wind deflectors and flows into the axially extending heat dissipation channel formed between the heat sinks. This heat exchange between the airflow and the heat sinks achieves rapid heat dissipation for the functional modules.

Therefore, they should not be construed as limitations on the embodiments of this application.

[0025] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0026] Existing drone countermeasure equipment typically integrates multiple functional modules, such as signal receiving and processing modules, signal generation modules, RF conditioning modules, power amplifier modules, and power supply modules, into a single housing to form a signal processing component (i.e., the main unit of the drone countermeasure equipment). However, the multiple functional modules are mainly arranged in a flat or stacked manner, which not only requires a large deployment space for the signal processing component, but also makes it easy for the heat generated by the functional modules to accumulate inside the housing, resulting in poor heat dissipation performance.

[0027] Therefore, to improve the integration and heat dissipation performance of signal processing components, this application provides a signal processing component including a mounting frame. Multiple functional modules can be mounted on the mounting frame circumferentially. The internal space of the mounting frame serves as a ventilation channel for airflow, and the airflow exchanges heat with the side of the functional modules facing inwards towards the mounting frame as it passes through the functional modules, thus removing the heat generated by the modules. This structure achieves high integration of the signal processing component while also providing efficient and stable heat dissipation for the functional modules.

[0028] In addition, to further improve the heat dissipation efficiency of the functional module, the signal processing component provided in this application has multiple heat sinks on the side of the functional module facing the inner side of the mounting frame to increase the heat dissipation area of ​​the functional module. At the same time, wind deflectors are also provided inside the mounting frame, so that when the airflow passes through the inside of the mounting frame, it can diffuse to the surroundings under the guidance of the wind deflectors and enter the gaps between the multiple heat sinks, thereby allowing the airflow to fully contact and exchange heat with the functional module and the heat sinks, which helps to improve the heat dissipation efficiency of the functional module.

[0029] According to one aspect of the embodiments of this application, a drone countermeasure device is provided. Please refer to... Figure 1 , Figure 1 The three-dimensional structure of the drone countermeasure device is shown. The drone countermeasure device 1 includes a signal processing component 100.

[0030] The signal processing component 100 can detect drone signals to perform drone reconnaissance, and can force illegally intruding drones to return, land, or hover by generating and transmitting jamming signals. The signal processing component 100 typically includes multiple functional modules such as a signal receiving and processing module, a signal generating module, a radio frequency conditioning module, a power amplifier module, and a power supply module. The signal receiving module is mainly used to detect drone signals, while the signal generating module, radio frequency conditioning module, and power amplifier module are used to generate jamming signals.

[0031] In addition, such as Figure 1 As shown, the UAV countermeasure device 1 also includes a bracket 200 and an antenna assembly 300. The bracket 200 is used to support and carry structures such as the signal processing component 100 and the antenna assembly 300. The bracket 200 can be designed as a tripod or a column structure. The bracket 200 can also integrate pitch and azimuth adjustment mechanisms to manually or automatically adjust the UAV countermeasure device 1 to align with the UAV target.

[0032] The antenna assembly 300 is used to convert the interference signal generated by the signal processing assembly 100 into electromagnetic waves for radiation, or to receive weak signals in the air. The antenna assembly 300 may include a directional antenna and / or an omnidirectional antenna. A directional antenna can concentrate the energy of the interference signal in one direction, thereby increasing the effective range of the interference signal, while an omnidirectional antenna can detect UAV remote control and image transmission signals in the air with 360-degree coverage, providing a wider coverage area. Preferably, the antenna assembly 300 includes at least one directional antenna and at least one omnidirectional antenna, to... Figure 1 Taking the structure shown as an example, the antenna assembly 300 includes three omnidirectional antennas (i.e., the disc antenna in the figure) and three directional antennas (i.e., the rod antenna in the figure).

[0033] According to another aspect of the embodiments of this application, a signal processing component is provided, which includes, but is not limited to, the drone countermeasure device 1 applied in the above embodiments. Please refer to... Figures 2 to 5 ,in, Figure 2 The three-dimensional structure of the signal processing component is shown. Figure 3 A partial structure of the signal processing component is shown. Figure 4 The cross-sectional structure of the signal processing component is shown. Figure 5 An exploded view of the signal processing assembly is shown. As shown, the signal processing assembly 100 includes a mounting frame 110, a wind deflector 120, a functional module 130, and an airflow drive mechanism 140.

[0034] like Figure 4 As shown, the mounting frame 110 serves as the physical load-bearing foundation and air duct housing for the entire signal processing component 100. The mounting frame 110 is a hollow prismatic frame structure, which can be made of metals such as aluminum alloy. The mounting frame 110 extends axially (i.e., along the axial direction...) Figure 2 An air inlet 111 is formed at one end of the mounting frame 110 (in the direction indicated by the double arrow M), and an air outlet 112 is formed at the other end. Specifically, the prism-shaped mounting frame 110 is open at both ends, so that a straight and continuous airflow channel is formed inside the mounting frame 110.

[0035] like Figure 3 and Figure 4 As shown, the baffle column 120 is the core airflow guiding component for constructing the internal airflow duct of the mounting frame 110. Specifically, it can be a cylindrical or polygonal prism structure located at the central axis of the mounting frame 110. The baffle column 120 is inserted inside the mounting frame 110, and an annular heat dissipation space 121 is formed between the outer peripheral wall of the baffle column 120 and the mounting frame 110. When a straight airflow enters the interior of the mounting frame 110 from the air inlet 111, the airflow encounters the baffle column 120, and the originally concentrated airflow is forced to change direction, spreading evenly to the surrounding annular heat dissipation space 121.

[0036] The outer peripheral sidewall of the windbreak column 120 can extend radially along the mounting frame 110 to form multiple fixing parts 122. These fixing parts 122 are spaced apart and can be fixedly connected to the mounting frame 110 by welding, screw fastening, or slot insertion, thereby achieving the assembly and fixation of the windbreak column 120 inside the mounting frame 110. Figure 5Taking the structure shown as an example, the fixing part 122 is a mounting plate 1221 set on the outer wall of the windbreak column 120. The mounting plate 1221 is bent at both ends along the radial direction of the mounting frame 110 to form a connecting part 1222, and the connecting part 1222 is provided with a through hole. Fasteners are passed through the connecting parts 1222 at both ends of the mounting plate 1221 and fixedly connected to the windbreak column 120 and the mounting frame 110, so that the installation of the windbreak column 120 can be completed.

[0037] In addition, in order to reduce airflow noise, such as Figure 4 As shown, the end of the wind deflector 120 facing the air inlet 111 can be tapered, meaning the end of the wind deflector 120 near the air inlet 111 gradually tapers, forming a smooth transition surface similar to a cone, ellipsoid, or teardrop, or it can be an inclined surface. This tapered end can be integrally formed with the main body of the wind deflector 120, or it can be designed as an independent air guide cap and fixedly connected to the end of the wind deflector 120 by interference fit, threaded connection, or screw fastening.

[0038] When airflow enters the mounting frame 110 from the air inlet 111, the airflow is guided by the smooth curved surface upon contact with the baffle column 120. The airflow gradually changes direction along the transition surface and flows outwards while conforming to the surface of the baffle column 120. In this structure, the constricted structure at the end of the baffle column 120 can cut through the airflow, allowing it to flow smoothly and steadily into the heat dissipation space 121 formed between the baffle column 120 and the mounting frame 110. This prevents the airflow from generating eddies due to a direct impact with the baffle column 120, effectively reducing airflow noise.

[0039] Functional module 130 is the core unit for signal processing in UAV reconnaissance, lateral movement, and attack. Multiple functional modules 130 exist, including signal receiving modules, signal generating modules, radio frequency conditioning modules, power amplifier modules, and power supply modules. The signal receiving module primarily receives aerial signals and filters, demodulates, and analyzes them to detect UAV signals. The signal generating module, radio frequency conditioning module, and power amplifier module generate interference signals and amplify their power to a sufficient factor, enabling the UAV countermeasure device 1 to have long-range radiation capabilities. The power supply module provides power to all functional modules 130.

[0040] like Figure 2 and Figure 3 As shown, multiple functional modules 130 are arranged along the circumference of the mounting frame 110 (i.e., Figure 2The module 130 (as indicated by the double arrow N) is mounted around the outer wall of the mounting frame 110. It can be connected via guide rails and grooves, bolt fastening, or snap-fit ​​connections. For example, guide rails can be installed on the outer wall of the mounting frame 110, and grooves can be provided on the functional module 130. The functional module 130 is installed by snapping the guide rails into the grooves; alternatively, bolts, pins, or other fasteners can be inserted into the fixing holes on the mounting frame 110 after passing through the through holes in the functional module 130.

[0041] This circumferential layout makes great use of the surface area of ​​the mounting frame 110, allowing the various functional modules 130 to fit together tightly in physical space, improving the integration of the signal processing component 100, shortening the transmission path of radio frequency signals between the various functional modules 130, and reducing signal attenuation.

[0042] Furthermore, when the number of functional modules 130 is large, in order to reduce the area occupied by the signal processing component 100 in the horizontal direction, multiple functional modules 130 can be arranged axially on the mounting frame 110. For example, assuming there are 8 functional modules 130 and the mounting frame 110 is a quadrangular prism, if all 8 functional modules 130 are mounted on the same layer of the mounting frame 110, the side length of the base of the mounting frame 110 will be at least the width of two functional modules 130. Figure 3 As shown, the components are installed in two layers around the mounting frame 110. The bottom side length of the mounting frame 110 is only composed of the width of one functional module 130, which effectively reduces the area occupied by the signal processing component 100 in the horizontal direction.

[0043] When arranging in layers, the vertical dimension of the internal space of the signal processing component 100 can also be used to divide different signal processing logic areas. For example, the power supply module, signal receiving module, signal generating module and RF conditioning module can be arranged in one layer as the core layer of the signal processing component 100, and multiple power amplifier modules can be arranged in one layer as the power amplifier layer of the signal processing component 100.

[0044] like Figures 3 to 5 As shown, the functional module 130 has multiple axially extending heat sinks 131 spaced apart on the side facing the interior of the mounting frame 110. These heat sinks 131 all extend into the heat dissipation space 121, and a heat dissipation channel 132 is formed between two adjacent heat sinks 131. The heat sinks 131 are fin-shaped structures made of high thermal conductivity materials (such as aluminum or copper). The heat sinks 131 can be integrally formed with the housing of the functional module 130 by die casting, or they can be bonded and fixed by attaching with a high thermal interface material (such as a thermal pad) and using thermally conductive adhesive.

[0045] The heat generated by the electronic components inside the functional module 130 is conducted to the housing of the functional module 130 and can quickly spread to the heat sinks 131 that extend into the heat dissipation space 121. After the airflow enters the narrow heat dissipation channel 132 formed between the heat sinks 131, it can carry away the heat on the heat sinks 131, so as to achieve heat dissipation of the functional module 130.

[0046] Functional modules 130 with different heat dissipation requirements can be equipped with heat sinks 131 of different lengths. For example, functional modules 130 with low heat generation can keep their temperature within a safe range even with only slight heat exchange, so they can be equipped with shorter heat sinks 131; while functional modules 130 with high heat generation can be equipped with taller heat sinks 131 to increase the heat dissipation area of ​​the corresponding functional modules 130.

[0047] The airflow drive mechanism 140 is the source component that provides the power for convective heat transfer, and can specifically be an axial fan, centrifugal fan, or brushless DC cooling fan, etc. Figure 4 and Figure 5 As shown, the airflow drive mechanism 140 is disposed at at least one end of the mounting frame 110 along the axial direction and is used to drive airflow through the air inlet 111 and the air outlet 112 and through the heat dissipation channel 132.

[0048] Specifically, the airflow drive mechanism 140 can be fixed to the axial end face of the mounting frame 110 by screws, so that the exhaust surface of the airflow drive mechanism 140 faces the air inlet 111 or the exhaust surface faces the air outlet 112. Taking the airflow drive mechanism 140 as an axial flow fan as an example, the airflow drive mechanism 140 can continuously draw air from the external environment into the heat dissipation space 121 directly at the air inlet 111 through the rotation of the fan blades, and drive the air to flow towards the end where the air outlet 112 is located, and finally discharge it from the air outlet 112. Alternatively, it can continuously discharge the air in the heat dissipation space 121 into the external environment at the air outlet 112, so that a negative pressure is formed inside the heat dissipation space 121, forcing the air from the external environment to enter the heat dissipation space 121 through the air inlet 111.

[0049] It should be noted that the signal processing component 100 may include only the airflow drive mechanism 140 provided at the air inlet 111 to draw air from the external environment into the heat dissipation space 121; or it may include only the airflow drive mechanism 140 provided at the air outlet 112 to discharge the airflow in the heat dissipation space 121 to the external environment; or it may provide airflow drive mechanisms 140 at both the air inlet 111 and the air outlet 112 to accelerate the airflow velocity in the heat dissipation space 121.

[0050] by Figure 4 and Figure 5 Taking the structure shown as an example, under the suction action of the airflow drive mechanism 140, the air from the external environment is drawn into the interior of the mounting frame 110 through the air inlet 111 at one end of the mounting frame 110. After the airflow enters the interior of the mounting frame 110, it impacts the wind deflector 120 head-on. Under the obstruction and guiding effect of the outer peripheral sidewall of the wind deflector 120, the high-speed airflow that was originally concentrated on the axis of the mounting frame 110 is forced to change direction and diffuse evenly in all directions, thus filling the annular heat dissipation space 121 formed between the wind deflector 120 and the mounting frame 110.

[0051] Subsequently, the evenly dispersed airflow will simultaneously enter the heat dissipation channel 132 surrounding the multiple functional modules 130 around the mounting frame 110. When the airflow passes through the heat dissipation channel 132, it can fully exchange heat with the heat sink 131 carrying the heat of the functional modules 130. After absorbing heat, the airflow temperature gradually increases and is finally discharged from the air outlet 112 at the other end of the mounting frame 110 along the axial direction.

[0052] In this embodiment, by circumferentially arranging multiple functional modules 130 on the mounting frame 110, the footprint and deployment space requirements of the signal processing component 100 are effectively reduced, and the integration of the signal processing component 100 is improved. Simultaneously, the internal space of the mounting frame 110 can also form an airflow channel. By inserting a baffle column 120 inside the mounting frame 110, a heat dissipation space 121 is formed between the mounting frame 110 and the baffle column 120. By providing heat sinks 131 extending into the heat dissipation space 121 on the functional modules 130, the airflow entering the mounting frame 110 can be diverted by the baffle column 120 and enter the axially extending heat dissipation channel 132 formed between the heat sinks 131. Thus, through heat exchange between the airflow and the heat sinks 131, rapid heat dissipation of the functional modules 130 is achieved.

[0053] Furthermore, in order to improve the heat dissipation efficiency of the functional module 130, in some embodiments, such as Figure 3 , Figure 4 and Figure 6 As shown, Figure 6 The diagram shows a top view of the signal processing assembly, with the end of the heat sink 131 facing away from the functional module 130 abutting against the side wall of the baffle column 120. Specifically, the heat sinks 131 of the functional module 130 extending into the heat dissipation space 121 have a sufficient height H so that the ends of these heat sinks 131 can contact and abut against the outer side wall of the baffle column 120 at the center of the mounting frame 110.

[0054] The end of the heat sink 131 can directly abut against the baffle column 120. For example, during assembly, the locking force of installing the functional module 130 onto the mounting frame 110 allows the end of the heat sink 131 to be directly pressed against the surface of the baffle column 120. To prevent hard contact wear, a layer of wear-resistant thermally conductive silicone pad or friction-reducing layer can be pre-attached to the corresponding position on the side wall of the baffle column 120. The end of the heat sink 131 can also be pre-set with an elastomer such as thermally conductive foam or silicone sealing strip. When the functional module 130 is installed onto the mounting frame 110, the elastomer is deformed under pressure and fills the gap between the heat sink 131 and the baffle column 120.

[0055] In this structure, when airflow enters the heat dissipation space 121, it prevents airflow from flowing away through the gap between the heat sink 131 (where resistance is low) and the baffle column 120, ensuring that the airflow enters the gap of the heat sink 131 (where resistance is high) as much as possible, thereby improving the heat dissipation efficiency of the functional module 130. Furthermore, after the heat sink 131 comes into contact with the baffle column 120, the heat on the heat sink 131 can be conducted to the baffle column 120 through the contact point, further improving the heat dissipation efficiency of the functional module 130.

[0056] Furthermore, considering the presence of machining tolerances and assembly clearances, a gap may exist between the end of the heat sink 131 and the baffle column 120, causing airflow to easily become turbulent at the entrance of the heat dissipation channel 132. Moreover, the airflow entering the heat dissipation channel 132 may also easily flow laterally into the gap between the heat sink 131 and the baffle column 120, resulting in airflow turbulence. Therefore, to avoid airflow turbulence, such as... Figure 3 , Figure 4 and Figure 6 As shown, the functional module 130 also includes a wind deflector 133, which covers the ends of the plurality of heat sinks 131 and abuts against the side wall of the wind deflector column 120.

[0057] The baffle plate 133 can be fixed to the end of the heat sink 131 by means of adhesive bonding, screw fixing, etc. Specifically, the end of the heat sink 131 can be pre-set with a slot, and a corresponding protrusion can be set on the baffle plate 133, or a protrusion can be pre-set on the end of the heat sink 131, and a corresponding slot (or through hole) can be set. When installing the baffle plate 133, the fixed connection can be achieved by inserting the protrusion into the slot and then applying adhesive or using a riveting process. Threaded holes can also be pre-drilled on the heat sink 131 and through holes can be opened on the baffle plate 133. The baffle plate 133 can be locked to the end face of the heat sink 131 array by passing a screw through the through hole and then screwing it into the threaded hole. When the functional module 130 is installed on the mounting frame 110, the baffle plate 133 can be directly attached to and abutted against the side wall of the baffle column 120, or a sealing gasket can be sandwiched between the two to achieve an interference fit.

[0058] When the airflow enters the heat dissipation space and flows to the heat dissipation channel 132 of each functional module 130, since the baffle plate 133 has sealed the end of the heat sink 131 and abutted against the baffle column 120 at the center, the airflow entering the heat dissipation channel 132 will pass smoothly through the narrow channel formed between adjacent heat sinks 131 under the constraint of the baffle plate 133.

[0059] Furthermore, during the process of airflow passing through the heat dissipation channel 132, even if the airflow flows away from the functional module 130 due to friction with the heat sink 131, it can still smoothly merge back into the main air duct under the guidance of the baffle plate 133 and continue to blow towards the air outlet 112.

[0060] In the above embodiments, by setting the baffle plate 133, the airflow is constrained, so that the airflow flowing through the heat dissipation channel 132 can flow smoothly along the extension direction of the heat sink 131, avoiding the airflow from running horizontally or spreading in eddies, ensuring that the airflow can fully exchange heat with the heat sink 131, which helps to improve the heat dissipation efficiency of the functional module 130.

[0061] Furthermore, since adjacent functional modules 130 form an angle when assembled circumferentially, if the edge heat sink 131 maintains a relatively high height, interference collisions will occur. If the heat sink 131 is not placed at the edge of the functional module 130, the heat dissipation efficiency of the functional module 130 will be affected. Therefore, in order to ensure the heat dissipation efficiency of the functional module 130 while avoiding interference, in some embodiments, such as... Figure 3 , Figure 6 and Figure 7 As shown, Figure 7 The three-dimensional structure of the functional module is shown. The multiple heat sinks 131 include multiple transition heat sinks 1311 located on both sides along the circumference of the mounting frame 110, and the multiple transition heat sinks 1311 gradually increase in height from both sides to the middle.

[0062] Specifically, among the heat sinks 131 of the functional module 130 facing the inner wall of the mounting frame 110, the heat sink 131 in the middle position is the highest, so as to extend into the heat dissipation space 121 to obtain the largest heat exchange area; while the transition heat sinks 1311 located on both sides of the functional module 130 gradually reduce in height along the circumference of the mounting frame 110, so that multiple transition heat sinks 1311 form a stepped or smooth slope cross section.

[0063] like Figure 8 As shown, Figure 8 Another partial structure of the signal processing component is shown, in which adjacent transition heat sinks 1311 on different functional modules 130 abut against each other in the circumferential direction of the mounting frame 110. Specifically, when two functional modules 130 are inserted and locked from adjacent sides of the mounting frame 110, Figure 8 From this perspective, multiple low-profile transition heat sinks 1311 on the right edge of functional module A and multiple low-profile transition heat sinks 1311 on the left edge of functional module B are aligned and meet at the corner of the mounting frame 110. The sides of the transition heat sinks 1311 can be abutted by mutual contact of planes, contact of inclined surfaces, or by a flexible thermal pad sandwiched in the middle.

[0064] This gradually transitioning heat sink 1311 design not only reserves structural clearance space but also maximizes the heat exchange area at the edges. When airflow enters the heat dissipation space 121, some airflow enters the heat dissipation channel 132 formed between the heat sinks 131 in the middle of the functional module 130 to serve as the main source of heat dissipation for the functional module 130. Other airflow enters the heat dissipation channel 132 formed by adjacent transition heat sinks 1311 at the edge of the functional module 130 to provide auxiliary heat dissipation for the functional module 130, effectively improving the heat dissipation efficiency of the functional module.

[0065] Furthermore, when the airflow enters the heat dissipation space 121, as the airflow continuously absorbs heat from the functional module 130, the temperature of the airflow itself will gradually increase along the flow direction. If the functional module 130 with high heat generation is installed at the air inlet 111, the temperature of the airflow will rise sharply after absorbing a large amount of heat. When this already heated airflow passes through the downstream functional module 130 with lower heat generation, it will not be able to generate an effective temperature difference, causing the downstream module to fail to dissipate heat.

[0066] Therefore, in order to ensure that multiple functional modules can effectively dissipate heat, in some embodiments, the functional modules 130 can be installed in layers according to their heat generation. For example, the functional modules 130 with lower heat generation can be installed on the mounting frame 110 at the end near the air inlet 111, and the functional modules 130 with higher heat generation can be installed on the mounting frame 110 at the end near the air outlet 112. That is, from the end where the air inlet 111 is located to the end where the air outlet 112 is located, the heat generated by the functional modules 130 gradually increases.

[0067] When the airflow drive mechanism 140 is activated, ambient temperature airflow is drawn in from the air inlet 111 and impacts the wind deflector 120 before spreading outwards. At this time, the heat generated by the functional module 130 (such as the power module or signal receiving module) located at the air inlet 111 is relatively small, and the passing airflow only needs to absorb a small amount of heat to keep the temperature of the functional module 130 within a safe range.

[0068] Subsequently, the airflow that has absorbed a small amount of heat continues to flow axially toward the air outlet 112. When this airflow that has absorbed a small amount of heat reaches the location of the high-heat-generating functional module 130 (such as the power amplifier module), there is still a large temperature difference between the airflow and the functional module 130. The airflow can normally carry away the heat generated by the functional module 130 through heat exchange, thereby controlling the temperature of the functional module 130 within a safe range.

[0069] In the above embodiment, by arranging and installing multiple functional modules 130 along the axial direction according to their heat generation, the airflow enters the heat dissipation space 121 from the air inlet 111 and passes through the low heat generation layer, the medium heat generation layer and the high heat generation layer in sequence. The temperature rise curve of the airflow matches the heat generation curve of the functional module 130, thereby ensuring that each functional module 130 can be efficiently cooled.

[0070] Furthermore, in order to protect the components inside the mounting frame 110, in some embodiments, such as Figure 1 and Figure 2 As shown, mounting covers 150 are respectively provided at both ends of the mounting frame 110 along the axial direction. The airflow drive mechanism 140 is disposed inside the mounting cover 150. At least one side of the mounting cover 150 along the circumferential direction of the mounting frame 110 is provided with ventilation holes 151. The ventilation holes 151 at both ends of the mounting frame 110 respectively form an air inlet 111 and an air outlet 112.

[0071] The mounting cover 150 can be fixedly installed on the end face of the mounting frame 110 by means of bolt locking, snap-fit, etc., and the airflow drive mechanism 140 is set inside the mounting cover 150 to prevent foreign objects from entering the mounting frame 110 from the air inlet 111 or air outlet 112, thereby protecting the airflow drive mechanism 140 and the heat sink 131.

[0072] Specifically, a mounting part can be provided on the inner bottom surface or side wall of the mounting cover 150, and the airflow drive mechanism 140 can be fixedly connected to the mounting part to achieve fixed installation of the airflow drive mechanism 140. At the same time, grid-like ventilation holes 151 can be opened on the outer wall of the mounting cover 150 to form an air inlet 111 and an air outlet 112 for gas exchange on the side wall of the mounting cover 150.

[0073] by Figure 4Taking the structure shown as an example, when the airflow drive mechanism 140 inside the mounting cover 150 is activated, ambient air is drawn in from the ventilation holes 151 on the side of the bottom mounting cover 150, and then flows vertically upward into the heat dissipation space 121 inside the mounting frame 110. The air then passes through the heat dissipation channel 132 formed by heat sinks 131 on each functional module 130, thus carrying away the heat generated by the functional modules 130. The air, having absorbed heat, converges inside the top mounting cover 150 and, driven by the airflow drive mechanism 140, is horizontally ejected from the ventilation holes 151 on the side of the top mounting cover 150.

[0074] Ventilation holes 151 can be opened on all four sides of the mounting cover 150 along the circumference of the mounting frame 110, so that the air from the outside environment can enter the interior of the mounting cover 150 evenly from all four sides, or the airflow inside the mounting cover 150 can be discharged evenly from all four sides, ensuring that the airflow around the wind deflector 120 inside the mounting frame 110 can flow evenly, thereby ensuring that the multiple functional modules 130 installed around the mounting frame 110 can dissipate heat evenly.

[0075] In addition, such as Figure 1 and Figure 2 As shown, the mounting cover 150 located at one end of the mounting frame 110 has a first mounting part 152, which is used to be fixedly connected to the bracket 200 of the UAV countermeasure device 1. The mounting cover 150 located at the other end of the mounting frame 110 has a second mounting part 153, which is used to mount the antenna assembly 300 of the UAV countermeasure device 1.

[0076] by Figure 1 Taking the structure shown as an example, the mounting cover 150 located at the bottom of the mounting frame 110 has a first mounting part 152. The first mounting part 152 can be multiple mounting holes opened on the outer bottom surface of the mounting cover 150. When installing the signal processing component 100, the mounting cover 150 can be locked to the pan-tilt panel of the bracket 200 by fasteners such as bolts and pins. Of course, the first mounting part 152 can also be a flange with multiple mounting holes set on the outer bottom surface of the mounting cover 150. When installing the signal processing component 100, the flange can be locked to the pan-tilt panel of the bracket 200 by bolts. Alternatively, the first mounting part 152 can also be a quick-release chuck with a locking structure set on the outer bottom surface of the mounting cover 150. When installing the signal processing component 100, the chuck can be directly inserted into the quick-release seat on the bracket 200 and locked by rotation.

[0077] The mounting cover 150 located at the top of the mounting frame 110 has a second mounting portion 153. This second mounting portion 153 can be multiple mounting holes opened on the top surface of the mounting cover 150. When installing the antenna assembly 300, the base of the antenna assembly 300 can be fitted against the top surface of the mounting cover 150, and bolts can be screwed through the base of the antenna assembly 300 into the mounting holes on the mounting cover 150. In addition, the top of the functional module 130 is also provided with an antenna interface 134. The radio frequency cable 302 of the antenna 301 in the antenna assembly 300 can be directly plugged into the antenna interface 134 on the top of the functional module 130 to realize the electrical connection between the antenna 301 and the functional module 130.

[0078] When installing the UAV countermeasure device 1, the bracket 200 is first firmly fixed on the bottom surface or other mounting planes. Then, the signal processing component 100 is fixedly installed on the bracket 200 through the first mounting part 152 of the bottom mounting cover 150. Then, the antenna assembly 300 is fixedly installed on the top of the signal processing component 100 through the second mounting part 153 of the top mounting cover 150.

[0079] In the above embodiment, by providing a mounting cover 150 and opening ventilation holes 151 on the mounting cover 150, the signal processing component 100 is ensured to dissipate heat normally, while protecting the airflow drive mechanism 140 and other components inside the mounting frame 110. Furthermore, the first mounting portion 152 and the second mounting portion 153 on the mounting covers 150 at both ends of the mounting frame 110 tightly combine the bracket 200, the signal processing component 100, and the antenna assembly 300, thus limiting the overall center of gravity of the UAV countermeasure device 1 to the bottom bracket 200 and improving the installation stability of the UAV countermeasure device 1.

[0080] Furthermore, in order to make the signal processing component 100 have a clean appearance, in some embodiments, such as Figure 2 and Figure 9 As shown, Figure 9 A partially exploded view of the signal processing assembly 100 is shown. In the circumferential direction of the mounting frame 110, at least one side of each functional module 130 has an interface 135, and a cable storage space 181 is formed between adjacent functional modules 130. The cable storage space 181 is used to accommodate cables 136 connected between the interfaces 135 on the multiple functional modules 130. The signal processing assembly 100 also includes a cover plate 160 connected between adjacent functional modules 130 and covering the cable storage space 181.

[0081] Interface 135 is a plug-in or connector located on the side of the housing of functional module 130, mainly used to realize electrical connection between functional modules 130. Interface 135 can be a multi-pin rectangular connector, an RF coaxial connector, or a waterproof circular aviation plug. Since multiple functional modules 130 are mounted along the circumference of the mounting frame 110, setting interface 135 on one side of the functional module 130 along the circumference of the mounting frame 110 makes the interfaces 135 on two adjacent functional modules 130 face each other. Only a shorter cable 136 is needed to realize electrical connection between two adjacent functional modules 130, effectively shortening the length of the cable 136 and reducing signal attenuation.

[0082] To form the cable storage space 181, positioning steps or spacers can be provided on the outer wall of the mounting frame 110, so that when multiple functional modules 130 are locked circumferentially along the mounting frame 110, a gap of a certain width is maintained between the side walls of two adjacent functional modules 130, so that the cables 136 between multiple functional modules 130 can be stored in the cable storage space 181.

[0083] The cover plate 160 can be fixed in the gap between two adjacent functional modules 130 by means of bolt locking, snap-fit, or slot engagement to create a wiring space for the cable 136. For example, slots extending axially are provided on the side walls of two adjacent functional modules 130. The cover plate 160 can be inserted axially into the slots on the two adjacent functional modules 130, and then pressed axially into the gap between the two functional modules 130 to complete the assembly of the cover plate 160.

[0084] In the above embodiment, the sidewall of the functional module 130 and the cover plate 160 enclose a cable storage space 181. On the one hand, the cable 136 is stored in the cable storage space 181 to avoid routing on the outside of the signal processing component 100 and to ensure the appearance of the signal processing component 100 is clean. On the other hand, the cover plate 160 can cover the cable storage space 181 to protect the cable 136 stored in the cable storage space 181 and prevent the cable 136 from being scratched by sharp objects.

[0085] Furthermore, to facilitate the movement of the signal processing component 100, in some embodiments, such as Figure 2 and Figure 9 As shown, the signal processing component 100 also includes a handle 170, which is located between two adjacent functional modules 130. The handle 170 extends axially, and its two ends are fixedly connected to the mounting frame 110, while its middle position is fixedly connected to the cover plate 160.

[0086] The handle 170 can be a metal bar with a grip curve or a non-slip texture. When the signal processing component 100 needs to be moved, the operator's fingers can naturally reach into the gap between the handle 170 and the cover plate 160 and grip the handle 170 to facilitate the movement of the signal processing component 100.

[0087] In addition, such as Figure 9 As shown, the handle 170 is located between two adjacent functional modules 130. The handle 170 and the functional module 130 are offset from each other along the circumference of the mounting frame 110, so that the user can directly open the cover 137 on the functional module 130 and maintain the circuit components 138 inside the functional module 130. This prevents the handle 170 from obstructing the user's view and makes the maintenance of the functional module 130 more convenient.

[0088] Regarding the installation method of the handle 170, a mounting part with threaded holes can be pre-set on the upper and lower edges of the mounting frame 110 at positions corresponding to the handle 170, and a through hole can be opened at the end of the handle 170. A bolt is then passed through the end of the handle 170 and locked to the mounting part on the mounting frame 110. Simultaneously, a mounting protrusion 171 is provided on the middle position of the handle 170 facing the cover plate 160, and a through hole is opened on the mounting protrusion 171. A threaded hole is provided at the corresponding position on the cover plate 160, and a bolt is then passed through the mounting protrusion 171 and locked to the cover plate 160.

[0089] In this structure, the cover plate 160 can be locked and fixed to the handle 170 first, and then the handle 170 can be fixedly installed on the mounting frame 110. This allows the cover plate 160 to be placed between two adjacent functional modules 130 and to cover the cable storage space 181, making the installation of the cover plate 160 and the handle 170 more convenient.

[0090] Regarding the specific structure of functional module 130, such as Figure 10 As shown, Figure 10 An exploded view of the functional module is shown. Functional module 130 includes a housing 139, a circuit assembly 138, and a cover 137.

[0091] A heat sink 131 is disposed on the outer side of the housing 139. An opening is provided on the side of the housing 139 opposite to the heat sink 131. The circuit assembly 138 is fixedly mounted inside the housing 139 through the opening, and the circuit assembly 138 is in close contact with the wall of the housing 139 where the heat sink 131 is disposed. This allows the heat generated by the circuit assembly 138 to be quickly conducted to the wall of the housing 139 where the heat sink 131 is disposed, thereby quickly dissipating heat through the heat sink 131. In addition, a thermal pad or thermal grease can be sandwiched between the circuit assembly 138 and the housing 139 to ensure rapid heat conduction.

[0092] The cover 137 is placed over the opening of the housing 139 and is sealed to the housing 139, so that a sealed space can be formed inside the housing 139 to accommodate the circuit assembly 138, giving the functional module 130 a high degree of waterproof performance. The cover 137 and the housing 139 can be sealed together by means of clamping a sealing element or filling with sealant.

[0093] When multiple functional modules 130 are mounted axially on the mounting frame 110, such as Figure 2 and Figure 3 As shown, in the axial direction of the mounting frame 110, an installation space 182 is formed between two adjacent functional modules 130. The installation space 182 can be used to install indicator light modules 183 to display the operating status of the signal processing component 100 through the indicator lights of the indicator light modules 183.

[0094] Furthermore, the mounting space 182 can be connected to the cable storage spaces 181 on both sides of the functional module 130 to form a wiring space on the signal processing component 100, allowing all cables 136 between multiple functional modules 130 to be routed and connected through the mounting space 182 and the cable storage space 181. A cover plate can also be installed on the mounting space 182 to cover it, ensuring that all cables 136 are stored within the mounting space 182 and the cable storage space 181, preventing wiring from running outside the signal processing component 100. This protects the cables 136 while ensuring the clean appearance of the signal processing component 100.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them.
