[0047] A drone is an unmanned aerial vehicle controlled by a radio remote control device or its own program control device. With the improvement of drone technology, drones are widely used in military and civilian fields. For example, drones are used for aerial photography, remote sensing, exploration, rescue, etc. However, advantages such as low cost, small size, and strong mobility make drones convenient for the public while also providing opportunities for illegal activities. Illegal drone flight activities (i.e., the phenomenon of drones flying without permission) pose a serious threat to the security of important government agencies, military facilities, and transportation hubs.

[0048] Therefore, it is necessary to take strong countermeasures against drones to ensure air safety. Specifically, navigation virtual signals can be sent to drones through navigation deception devices to conduct directional repulsion, hover deception, etc. on drones. However, most of the existing navigation deception devices are box-type or fixed-type designs. The devices are large in volume and heavy in weight, making it difficult to achieve rapid individual deployment and transfer. Moreover, when linked with portable countermeasure devices, they can only be fixed near the navigation deception devices and cannot move at any time, resulting in poor linkage effects.

[0049] To solve the problem that existing navigation spoofing devices are difficult to achieve rapid single-soldier deployment and transfer, the inventors of this application conducted in-depth research and found that a backpack component can be provided on the housing of the navigation spoofing device. When using the navigation spoofing device, the user can carry the navigation spoofing device on the back, chest, etc. through the backpack component to move, thus achieving rapid single-soldier deployment and transfer. In addition, to make it more convenient for the navigation spoofing device to be linked with a portable countermeasure device, when designing the navigation spoofing device, the inventors of this application also integrated the power supply unit, the navigation spoofing unit, and the network interaction unit into the housing of the navigation spoofing device. When linked with the portable countermeasure device, the power supply unit and the portable countermeasure device can be electrically connected through a cable, so that the power supply unit supplies power to the portable countermeasure device. In this way, there is no need to set a power supply on the portable countermeasure device, achieving the lightweight of the portable countermeasure device and improving the comfort of single-soldier operations. The network interaction unit and the portable countermeasure device can also be electrically connected through a cable, enabling the navigation spoofing device to communicate with the portable countermeasure device and making it more convenient during joint operations.

[0050] However, the power supply unit, the navigation spoofing unit, and the network interaction unit generate a large amount of heat during operation. If this heat is directly conducted to the surface of the housing in contact with the user's body, it is easy to cause burns. Therefore, to ensure the safety of the navigation spoofing device, the inventors of this application conducted in-depth research and designed a navigation spoofing device. The device includes a first housing and a second housing. The power supply unit, the navigation spoofing unit, and the network interaction unit are electrically connected to each other in pairs and arranged in the first housing. The second housing provided with the backpack component covers the installation opening on one side of the first housing and is connected to the first housing. There are gaps between the second housing and the power supply unit, the navigation spoofing unit, and the network interaction unit, so that the backpack position of the navigation spoofing device and the heat dissipation module are separated, effectively reducing the heat conducted to the second housing and avoiding burns to the user.

[0051] Please refer to Figure 1 , Figure 1 FIG. shows an application scenario diagram of the drone countermeasure system provided by the embodiment of the present invention. The user can carry the navigation spoofing device 100 on the back and carry the handheld anti-drone device 200 to achieve joint countermeasures against the target drone. The handheld anti-drone device 200 can be a strike device, such as a drone countermeasure gun, a drone interceptor, a laser weapon, etc., or a detection device, such as a radar detection device, a spectrum detection device, etc. In the embodiment of this application, only the handheld anti-drone device 200 is taken as an example of a strike device for illustration.

[0052] After the navigation spoofing device 100 recognizes the navigation signal of the target drone, it will simulate the signals of the global navigation satellite system (e.g., GPS, GLONASS, Galileo, etc.). These simulated signals are similar to the real satellite signals in terms of frequency, format, and encoding, making it difficult for the drone to distinguish. Then, these simulated navigation signals are transmitted, so that after the navigation system of the drone receives these simulated navigation signals, it starts to rely on these signals for positioning and navigation. Once the navigation system of the drone is controlled by the simulated navigation signals, the user can guide the drone to perform specific actions, such as changing the flight path, decelerating, stopping, or landing, etc.

[0053] When the handheld anti-drone device 200 is linked with the navigation spoofing device 100, first, after the navigation spoofing device 100 recognizes the navigation signal of the drone, it lures the drone to hover at a certain position by transmitting simulated navigation signals. Then, the user views the position of the target drone through the display screen on the handheld anti-drone device 200, and after determining the position of the target drone, uses the handheld anti-drone device 200 to shoot down the target drone.

[0054] According to one aspect of the embodiments of the present application, please refer to Figure 2 and Figure 3 , Figure 2 shows a perspective view of the navigation spoofing device provided by the embodiments of the present utility model, Figure 3 shows a cross-sectional view of the navigation spoofing device provided by the embodiments of the present utility model. A navigation spoofing device is provided. The navigation spoofing device 100 includes a first housing 110, a second housing 120, a power supply unit 130, a navigation spoofing unit 140, and a network interaction unit 150. An installation opening 111 is provided on one side of the first housing 110. The power supply unit 130, the navigation spoofing unit 140, and the network interaction unit 150 are arranged inside the first housing 110, and the power supply unit 130, the navigation spoofing unit 140, and the network interaction unit 150 are electrically connected to each other pairwise. The second housing 120 covers the installation opening 111 and is connected to the first housing 110. There are gaps between the second housing 120 and the power supply unit 130, the navigation spoofing unit 140, and the network interaction unit 150. A carrying assembly 121 is provided on the second housing 120, and the carrying assembly 121 is used to carry the navigation spoofing device 100.

[0055] As Figure 2As shown, the first housing 110 and the second housing 120 are used to cooperate with each other to form a space for accommodating various functional components (such as a power supply unit 130, a navigation deception unit 140, a network interaction unit 150, etc.) on the navigation deception device 100. In addition, in order to meet the requirements of the military field for the stability and durability of the device, the first housing 110 and the second housing 120 can be made of metal materials, such as materials like aluminum, iron, iron alloy, etc. Further, in order to make the navigation deception device 100 meet the requirement of light weight, the materials of the first housing 110 and the second housing 120 can adopt magnesium alloy with a lower density.

[0056] As Figure 4 shown, Figure 4 The exploded view of the navigation deception device provided by the embodiment of the present invention is shown. The main space for accommodating various functional components is formed inside the first housing 110, and an installation opening 111 is provided on one side thereof for various functional components to enter and be installed inside the first housing 110. The power supply unit 130, the navigation deception unit 140, and the network interaction unit 150 are all arranged inside the first housing 110. Specifically, as Figure 3 shown, the power supply unit 130 can be stacked with the navigation deception unit 140 and the network interaction unit 150 in the direction shown by the Y axis. The navigation deception unit 140 and the network interaction unit 150 can be arranged in the direction shown by the Z axis above the power supply unit 130, so that the space inside the first housing 110 is used to the maximum extent.

[0057] The carrying assembly 121 on the second housing 120 is used to carry the navigation deception device 100. As Figure 2 shown, the carrying assembly 121 includes a first connection part 1211 located at the upper end of the second housing 120 and a second connection part 1212 located at the lower end of the second housing 120. When it is necessary to carry the navigation deception device 100, after selecting a suitable shoulder strap, one end of the shoulder strap can be fixedly connected to the first connection part 1211, and the other end can be fixedly connected to the second connection part 1212, and then the navigation deception device 100 can be carried by the shoulder strap. Of course, the carrying assembly 121 can be a shoulder strap fixedly arranged on the second housing 120, and an adjustment strap can also be arranged on the shoulder strap, so that the user can adjust the length of the shoulder strap according to his own height and body type to improve comfort. In addition, the carrying assembly 121 can also include a waist belt arranged on the second housing 120, which can effectively improve the stability when the user carries the navigation deception device 100.

[0058] When the user carries the navigation spoofing device 100 through the carrying component 121, the outer surface of the second housing 120 usually comes into contact with the user's body, and the power supply unit 130, the navigation spoofing unit 140, and the network interaction unit 150 all generate heat during the operation of the navigation spoofing device 100. If the second housing 120 covers the installation opening 111 and fits with one or more of the power supply unit 130, the navigation spoofing unit 140, and the network interaction unit 150, the heat generated by the fitting unit will be directly conducted to the second housing 120, resulting in a relatively high outer surface temperature of the second housing 120 and being prone to scalding the user.

[0059] Therefore, to avoid scalding the user, as Figure 3 shown, there are gaps between the second housing 120 and the power supply unit 130, the navigation spoofing unit 140, and the network interaction unit 150. When the navigation spoofing unit 140 and the network interaction unit 150 are arranged along the direction shown by the Z-axis, there is also a distance D1 between the structure on the network interaction unit 150 closest to the second housing 120 and the second housing 120, so that the heat generated by the power supply unit 130, the navigation spoofing unit 140, and the network interaction unit 150 will not be directly conducted to the second housing 120. In addition, the middle part of the second housing 120 is recessed towards the first housing 110 to form a groove with a depth of D2, which can reduce the contact area between the user's body and the second housing 120 when carrying the navigation spoofing device 100 and further avoid the occurrence of scalding incidents.

[0060] The power supply unit 130 is used for system power supply, that is, for supplying power to the components inside the navigation spoofing device 100. In addition, the power supply unit 130 can also be electrically connected to the handheld anti-drone device through a cable to supply power to the handheld anti-drone device, that is, transfer the power of the handheld anti-drone device to the navigation spoofing device 100, reducing the weight of the handheld anti-drone device. And since the navigation spoofing device 100 is a backpack-type device, the transferred power makes its felt weight smaller or even negligible, effectively improving the convenience of individual combat.

[0061] The navigation spoofing unit 140 is used to obtain the navigation signal of the target drone and generate a navigation simulation signal. Specifically, as Figure 2 and Figure 4As shown in the figure, an antenna 170 is further provided on the first housing 110. The antenna 170 includes a receiving antenna and a transmitting antenna. The receiving antenna is used to identify the navigation signal of the target UAV. When the receiving antenna identifies the navigation signal, it will send the navigation signal to the navigation spoofing unit 140 so that the navigation spoofing unit 140 generates a navigation simulation signal. The navigation spoofing unit 140 sends the navigation simulation signal to the transmitting antenna so that the transmitting antenna transmits the navigation simulation signal, and then the target UAV starts to rely on the navigation simulation signal for positioning and navigation after receiving the navigation simulation signal. The antenna 170 can be detachably connected to the first housing 110 through a connecting member 171. The connecting member 171 can connect the antenna 170 to the first housing 110 by means of threaded connection, snap connection, etc. When it is necessary to store the navigation spoofing device 100, the antenna 170 can be directly detached from the first housing 110, making the packaging and transportation of the navigation spoofing device 100 more convenient.

[0062] The network interaction unit 150 is used to communicate with the handheld anti-UAV device when the navigation spoofing device 100 is electrically connected to the handheld anti-UAV device. In an embodiment of the present application, as an example, when the handheld anti-UAV device is a strike device, after the navigation spoofing unit 140 obtains the navigation signal, it will send the navigation signal and the navigation simulation signal to the network interaction unit 150. The network interaction unit 150 analyzes the navigation signal and the navigation simulation signal to obtain information such as the position, flight altitude, and flight direction of the target UAV, and then generates a fusion countermeasure signal according to this information and sends it to the handheld anti-UAV device to display the information such as the position, flight altitude, and flight direction of the target UAV on the display of the handheld anti-UAV device. The user can directly strike the target UAV according to the display on the handheld anti-UAV device.

[0063] In the above embodiment, a backpack component 121 is provided on the second housing 120 of the navigation spoofing device 100, so that the user can carry the navigation spoofing device 100 on the back, chest and other positions through the backpack component 121 for movement, realizing rapid single-soldier deployment and transfer. At the same time, there are gaps between the second housing 120 and the power supply unit 130, the navigation spoofing unit 140, and the network interaction unit 150, so that the backpack position of the navigation spoofing device 100 is separated from the heat dissipation module in different areas, reducing the heat conducted to the backpack position and avoiding scalding the user. In addition, a network interaction unit 150 is provided in the navigation spoofing device 100, so that after the handheld anti-UAV device is electrically connected to the navigation spoofing device 100, communication can be directly carried out through the network interaction unit 150, which is more convenient during joint operations.

[0064] To further ensure the safety of the navigation spoofing device, in some embodiments of the present application, such as Figure 3 and Figure 4As shown in the figure, the navigation spoofing device 100 further includes a power amplifier module 160. The power amplifier module 160 is electrically connected to the navigation spoofing unit 140. The power amplifier module 160 is fixedly attached to the inner wall of the first housing 110 opposite to the second housing 120. The inner wall of the first housing 110 where the power amplifier module 160 is disposed is further provided with a first heat-conducting mounting bracket 112. The navigation spoofing unit 140 is connected to the first heat-conducting mounting bracket 112, and the navigation spoofing unit 140 is located on the side of the power amplifier module 160 facing the mounting port 111.

[0065] The navigation analog signal generated by the navigation spoofing unit 140 according to the navigation signal is usually relatively weak. Therefore, in order to make the coverage range of the navigation analog signal wider, a power amplifier module 160 is usually provided inside the navigation spoofing device 100 to amplify the navigation analog signal, and then the amplified navigation spoofing signal is transmitted by the antenna 170. When the power amplifier module 160 amplifies the navigation analog signal, a large amount of electrical energy will be converted into heat energy, and the semiconductor devices (such as transistors) on the power amplifier module 160 will also generate heat when conducting electricity, especially when they work in a non-optimal working area, the heat generation will be more serious. This results in that during the operation of the navigation spoofing device 100, the heat generated by the power amplifier module 160 is much greater than the heat generated by other units inside the navigation spoofing device 100.

[0066] Therefore, it is necessary to set the power amplifier module 160 as far away from the second housing 120 as possible. As Figure 3 shown, the power amplifier module 160 can be set on the inner wall of the first housing 110 opposite to the second housing 120, and the power amplifier module 160 is attached to the inner wall of the first housing 110, so that the heat generated by the power amplifier module 160 is directly dissipated through the first housing 110. Further, in order to enable the heat generated by the power amplifier module 160 to be conducted to the first housing 110 as much as possible, a heat-conducting substance with good heat-conducting performance such as heat-conducting silicone grease can also be filled between the power amplifier module 160 and the inner wall of the first housing 110, so that the heat of the power amplifier module 160 is transferred to the first housing 110 through the heat-conducting silicone grease for heat dissipation.

[0067] In addition, since the thickness of the power amplifier module 160 is usually relatively small, in order to effectively improve the utilization rate of the internal space of the first housing 110, the navigation spoofing unit 140 and the power amplifier module 160 can be stacked. As Figure 4 shown, a first heat-conducting mounting bracket 112 with a height greater than the thickness of the power amplifier module 160 can be provided on the inner wall of the first housing 110 where the power amplifier module 160 is disposed, so that after the navigation spoofing unit 140 is set on the first heat-conducting mounting bracket 112, it is located on the side of the power amplifier module 160 facing the mounting port 111. Of course, the first heat-conducting mounting bracket 112 is Figure 4In addition to the installation posts shown, when the navigation spoofing unit 140 includes multiple independent modules, the first heat-conducting mounting bracket 112 may further include a mounting plate parallel to the power amplifier module 160. The navigation spoofing unit 140 can be arranged on the mounting plate, and then the mounting plate is fixedly connected to the installation posts.

[0068] In the above embodiment, the power amplifier module 160 with the largest heat generation in the navigation spoofing device 100 is arranged on the side wall of the first housing 110 opposite to the second housing 120. On the one hand, the distance between the power amplifier module 160 and the second housing 120 is increased, thereby reducing the heat generated by the power amplifier module 160 from spreading to the second housing 120. On the other hand, the power amplifier module 160 is in contact with the inner wall of the first housing 110, and the heat generated by it can be directly conducted to the first housing 110 for heat dissipation. In addition, the navigation spoofing unit 140 and the power amplifier module 160 are stacked horizontally, which can not only improve the utilization rate of the internal space of the first housing 110, but also the navigation spoofing unit 140 can block between the power amplifier module 160 and the second housing 120, so that the heat generated by the power amplifier module 160 cannot be directly conducted to the second housing 120 through the air, further reducing the heat conducted to the second housing 120.

[0069] During the operation of the navigation induction device, the heat generated by the navigation induction unit is more than that generated by the network interaction unit. Therefore, in some embodiments of the present application, in order to further ensure that the heat will not be conducted to the second housing, such as Figure 3 and Figure 4 as shown, a second heat-conducting mounting bracket 113 is further provided on the inner wall of the first housing 110 where the power amplifier module 160 is arranged. The network interaction unit 150 is connected to the second heat-conducting mounting bracket 113, and the network interaction unit 150 is located on the side of the navigation spoofing unit 140 facing the installation port 111.

[0070] Such as Figure 4As shown, the height of the second heat-conducting mounting bracket 113 is higher than that of the first heat-conducting mounting bracket 112, such that after the network interaction unit 150 is connected to the second heat-conducting mounting bracket 113, it is located on the side of the navigation spoofing unit 140 facing the mounting opening 111. The network interaction unit 150 includes a mounting bracket 151, a network switch 152, and a communication control circuit board 153. The network switch 152 and the communication control circuit board 153 are both disposed on the same side of the mounting bracket 151. The mounting bracket 151 is connected to the second heat-conducting mounting bracket 113, and the network switch 152 and the communication control circuit board 153 are located on the side of the mounting bracket 151 facing the mounting opening 111. By disposing the network switch 152 and the communication control circuit board 153 on the mounting bracket 151 and then connecting the mounting bracket 151 to the second heat-conducting mounting bracket 113, not only can the stability of the network interaction unit 150 within the first housing 110 be enhanced, but also the internal structure of the first housing 110 can be made more concise and compact.

[0071] Further, to meet the requirement of lightweight of the navigation spoofing device 100, as Figure 5 shown, Figure 5 FIG. shows an exploded view of another angle of the navigation spoofing device provided by an embodiment of the present invention. Through holes 1511 can be formed in the mounting bracket 151 at positions where connection structures do not need to be provided on the mounting bracket 151, effectively reducing the weight of the mounting bracket 151. Secondly, to ensure the strength of the mounting bracket 151, reinforcing protrusions 1512 can also be provided at the edges of the through holes 1511 on the mounting bracket 151, and the reinforcing protrusions 1512 are located on the side of the mounting bracket 151 facing away from the network switch 152. Such a structure can not only ensure that the mounting bracket 151 remains unchanged and does not deform when the navigation spoofing device 100 is impacted, dropped, or subjected to other impacts, but also when the navigation spoofing unit 140 and the mounting bracket 151 are disposed in a fitting manner, the reinforcing protrusions 1512 can also create a gap between the navigation spoofing unit 140 and the network switch 152 and the communication control circuit board 153, thereby accelerating the heat dissipation rate of the navigation spoofing unit 140 and the network interaction unit 150.

[0072] In the above embodiment, by stacking the network interaction unit 150 and the navigation spoofing unit 140 through the second heat-conducting mounting bracket 113, the space utilization rate within the navigation spoofing device 100 can be effectively improved, and the volume of the navigation spoofing device 100 can be reduced. In addition, by disposing the network interaction unit 150 with relatively small heat generation on the side close to the mounting opening 111, such that the network interaction unit 150 can block between the navigation spoofing unit 140 and the second housing 120, the heat generated by the navigation spoofing unit 140 cannot be directly conducted to the second housing 120 through air, which can further reduce the heat conducted to the second housing 120.

[0073] Due to the relatively complex operating environment in the military field, navigation deception devices usually need to have high strength. Therefore, the housing of navigation deception devices is usually made of metal materials. However, when both the first housing and the second housing are made of metal materials with good thermal conductivity, heat will quickly conduct from the first housing to the second housing when they come into contact, resulting in a relatively high temperature of the second housing. Therefore, in order to further prevent the heat on the first housing from conducting to the second housing, in some embodiments of the present application, as Figure 6 shown Figure 6 shows Figure 3 an enlarged view of part A in, an insulating member 180 is interposed between the first housing 110 and the second housing 120.

[0074] The insulating member 180 can be made of a silica gel member, a rubber member, a heat-insulating sealing strip, etc. When fixing the first housing 110 and the second housing 120, the insulating member 180 can isolate the first housing 110 and the second housing 120 from each other, preventing the first housing 110 and the second housing 120 from directly contacting each other. Specifically, the insulating member 180 can be directly clamped between the first housing 110 and the second housing 120, or grooves can be provided on the first housing 110 and the second housing 120, and the insulating member 180 can be arranged in the grooves.

[0075] In the embodiments of the present application, as an example, as Figure 6 shown, grooves can be formed on the edge of the first housing 110, the insulating member 180 can be arranged in the grooves, and protrusions can be provided at corresponding positions on the second housing 120. When installing the navigation deception device 100, the protrusions on the second housing 120 are inserted into the grooves on the first housing 110, and then the first housing 110 and the second housing 120 are connected by connecting members such as screws and bolts, so that the protrusions on the second housing 120 are pressed against the insulating member 180. At this time, a gap D3 can still exist between the first housing 110 and the second housing 120, effectively preventing the first housing 110 and the second housing 120 from directly contacting each other.

[0076] In the above embodiments, by arranging the insulating member 180 between the first housing 110 and the second housing 120, not only can the contact between the first housing 110 and the second housing 120 be avoided, reducing the heat conduction from the first housing 110 to the second housing 120, but also the insulating member 180 can enhance the sealing performance between the first housing 110 and the second housing 120, preventing substances such as liquid and dust from entering the interior of the navigation deception device 100.

[0077] In order to make the deception range of the navigation deception device wider, it is necessary to increase the power of the power amplifier module, which will cause a large amount of heat generated by the power amplifier module. If the first housing cannot dissipate heat in time, the heat generated by the power amplifier module will accumulate continuously, causing the overall temperature of the navigation deception device to rise, and then leading to the problem that the second housing cannot avoid temperature increase. Therefore, in order to accelerate the heat dissipation speed of the first housing, in some embodiments of the present application, such as Figure 5 、 Figure 7 and Figure 8 shown, Figure 7 shows another cross-sectional view of the navigation deception device provided by the embodiment of the present invention, Figure 8 shows a cross-sectional view of the navigation deception device provided by the embodiment of the present invention from another angle. A radiator 190 is arranged at a position on the outer surface of the first housing 110 opposite to the power amplifier module 160. The radiator 190 includes a third housing 191, heat dissipation fins 192 and a heat dissipation device 193. The third housing 191 covers the outer surface of the first housing 110. Both the heat dissipation fins 192 and the heat dissipation device 193 are arranged inside the third housing 191. An air inlet 194 and an air outlet 195 are formed on the third housing 191. The side of the heat dissipation fin 192 is attached to the position on the outer surface of the first housing 110 opposite to the power amplifier module 160. The number of the heat dissipation fins 192 is multiple, and a heat dissipation channel 196 is formed between the heat dissipation fins 192. The heat dissipation channel 196 is communicated with the air inlet 194 and the air outlet 195. The heat dissipation device 193 is arranged at one end of the heat dissipation channel 196. The heat dissipation device 193 is used to drive the fluid to enter the third housing 191 from the air inlet 194 and discharge from the air outlet 195 through the heat dissipation channel 196.

[0078] The radiator 190 is used to transfer the heat from the first housing to the external environment to prevent the navigation deception device from overheating. The radiator 190 can be an air radiator or a liquid radiator. In the example of the present application, in order to ensure the light weight of the navigation deception device 100, an air radiator can be used as the radiator 190 of the navigation deception device 100.

[0079] Specifically, a plurality of heat dissipation fins 192 can be arranged at a position on the first housing 110 opposite to the power amplifier module 160, such as Figure 7 and 8As shown, multiple heat sinks 192 can be arranged parallel to each other along the direction shown by the X-axis. There is a gap between every two adjacent heat sinks 192, and a heat dissipation channel 196 parallel to the direction shown by the Y-axis is formed to increase the contact area between the first housing 110 and the air, and accelerate the heat dissipation speed of the first housing 110. Of course, multiple heat sinks 192 can also be arranged along the direction shown by the Y-axis to form a heat dissipation channel 196 parallel to the direction shown by the X-axis. In addition, when the first housing 110 is made of a metal material, the first housing 110 and the heat sinks 192 can also be integrally injection-molded, making the processing of the navigation spoofing device 100 more convenient.

[0080] In order to accelerate the air flow rate in the heat dissipation channel 196 to accelerate the heat dissipation speed of the first housing 110, as Figure 7 shown, a heat dissipation device 193 can be arranged above the heat sinks 192, and a third housing 191 is arranged to cover the heat sinks 192 and the heat dissipation device 193. In addition, as Figure 5 shown, an air outlet 195 can be opened at a position on the third housing 191 opposite to the heat dissipation device 193, and an air inlet 194 can be opened at a position on the third housing 191 opposite to the end of the heat dissipation channel 196 away from the heat dissipation device 193, so that the air inside the third housing 191 can communicate with the air outside the third housing 191. The heat dissipation device 193 can be a fan, specifically an axial flow fan, an exhaust fan, etc.

[0081] Specifically, after the heat dissipation device 193 is turned on, it will drive the air inside the third housing 191 to be discharged from the air outlet 195, so that the air inside the third housing 191 is reduced. At this time, the air outside the third housing 191 will enter the third housing 191 from the air inlet 194 to make up for it. Then, the air entering the third housing 191 flows through the heat dissipation channel 196 towards the air outlet 195 under the drive of the heat dissipation device 193, and exchanges heat with the heat sinks 192 during the flow. Finally, the air that has completed the heat exchange will be discharged from the air outlet 195 under the drive of the heat dissipation device 193, thereby bringing the heat of the heat sinks 192 to the outside of the third housing 191.

[0082] It should be particularly noted that in addition to being arranged opposite to the air outlet 195 to drive the air inside the third housing 191 to flow towards the outside of the third housing 191, the heat dissipation device 193 can also be arranged opposite to the air inlet 194 to drive the air outside the third housing 191 to flow into the third housing 191. In addition to being arranged on the wall of the third housing 191 opposite to the first housing 110, the air inlet 194 and the air outlet 195 can also be arranged on the side wall in contact with the first housing 110, as long as it is ensured that the heat dissipation channel 196 is connected to the air outlet 195 and the air inlet 194.

[0083] In addition, to prevent the fluid from flowing from between the heat sink 192 and the third housing 191 to the air outlet 195 without passing through the heat dissipation channel 196, that is, as Figure 8 shown, to prevent the fluid from directly flowing from above the heat sink 192 to the air outlet 195, a baffle 197 can be provided between the heat sink 192 and the third housing 191. As Figure 5 and Figure 8 shown, a baffle 197 is provided on the side of the heat sink 192 opposite to the first housing 110. The baffle 197 covers the position where the heat dissipation channel 196 does not need to communicate with the air inlet 194 and the air outlet 195, so that after the fluid enters the interior of the third housing 191 from the air inlet 194, it can only flow to the air outlet 195 through the heat dissipation channel 196, ensuring that the fluid entering the interior of the third housing 191 can fully exchange heat with the heat sink 192.

[0084] In the above embodiments, by providing the radiator 190 at the position on the first housing 110 opposite to the power amplifier module 160, the heat dissipation speed of the first housing 110 is accelerated, preventing the navigation spoofing device 100 from overheating due to heat accumulation. Specifically, by providing the heat sink 192 to increase the contact area of the first housing 110, the heat exchange speed between the first housing 110 and the fluid is made faster. A heat dissipation device 193 is also provided at one end of the heat dissipation channel 196 formed by the heat sink 192 to accelerate the speed of the fluid passing through the heat dissipation channel 196, effectively accelerating the heat dissipation speed of the first housing 110.

[0085] To make the use of the navigation spoofing device more convenient, in some embodiments of the present application, as Figure 3 、 Figure 5 and Figure 7 shown, the power supply unit 130 includes a power source 131 and a power control circuit board 132. A power supply compartment 114 is provided on the first housing 110. The power source 131 is detachably installed in the power supply compartment 114. The power control circuit board 132 is disposed in contact with the surface of the power supply compartment 114 facing the interior space of the first housing 110 and is used to be electrically connected to the power source 131 when the power source 131 is installed in the power supply compartment 114.

[0086] The power source 131 is used to supply power to the navigation spoofing device 100. The power source 131 can be a storage battery, specifically a lithium-ion battery, a lithium-sulfur battery, a lead-acid battery, etc. The power control circuit board 132 is used to control the power source 131 to supply power to the navigation spoofing device 100. When it is necessary to link the navigation spoofing device 100 and the handheld anti-jamming device, the power control circuit board 132 can also be electrically connected to the handheld anti-jamming device through a cable to control the power source 131 to supply power to the handheld anti-jamming device.

[0087] As Figure 3 and Figure 5As shown in the figure, the side wall of the first housing 110 opposite to the second housing 120 is recessed into the inner space of the first housing 110 to form a power supply compartment 114, and the power supply 131 is detachably installed in the power supply compartment 114. Specifically, the power supply 131 can be connected to the power supply compartment 114 by means of magnetic attraction, snap connection, etc. Of course, the power supply compartment 114 can also be formed by the side wall of the first housing 110 adjacent to the second housing 120 being recessed into the inner space of the first housing 110. When multiple power supplies 131 are arranged inside the first housing 110, two power supply compartments 114 can be adjacently opened at the same position of the first housing 110, or power supply compartments 114 can be respectively arranged on the opposite side walls of the first housing 110.

[0088] As Figure 3 shown in the figure, the power supply control circuit board 132 can be arranged on the surface of the power supply compartment 114 opposite to the second housing 120 and be attached to the surface of the power supply compartment 114, so that the heat generated by the power supply control circuit board 132 can be conducted to the first housing 110 through the wall of the power supply compartment 114. When the power supply compartment 114 is formed by the side wall of the first housing 110 opposite to the second housing 120 being recessed into the inner part of the first housing 110, the heat generated by the power supply control circuit board 132 can also be conducted in the direction away from the second housing 120.

[0089] In addition, as Figure 5 shown in the figure, a top cover 1141 can also be arranged on the first housing 110 to cover the opening 1142 of the power supply compartment 114 to protect the power supply 131. Specifically, the top cover 1141 can be rotatably connected to the first housing 110 through components such as a pin shaft and a hinge, and a hook 1143 is arranged on the top cover 1141, and a snap projection 1144 is arranged at a position on the first housing 110 opposite to the hook 1143. When it is necessary to replace the corresponding power supply 131, the hook 1143 is separated from the snap projection 1144, and the top cover 1141 is rotated to expose the power supply 131 for quick replacement of the power supply 131. After the replacement of the power supply 131 is completed, the top cover 1141 is rotated to cover the opening 1142, and the hook 1143 and the snap projection 1144 are snapped (i.e., in the state as Figure 5 shown in the figure) to fix the top cover 1141 at the position covering the opening 1142.

[0090] In the above embodiments, the power supply bin 114 is provided to install the power supply 131, making the disassembly and assembly of the power supply 131 more convenient. When the power of the power supply 131 is insufficient, the power supply 131 can be directly and quickly replaced, without having to fix the navigation spoofing device 100 in one position and charge the power supply 131 through a cable, thus shortening the standby time of the navigation spoofing device 100. In addition, by arranging the power control circuit board 132 in contact with the surface of the power supply bin 114, the heat generated by the power control circuit board 132 can be conducted through the wall of the power supply bin 114 to the first housing 110 for heat dissipation, reducing the heat conducted to the second housing 120.

[0091] As Figure 5 shown, a plurality of electronic components 1321 are provided on the power control circuit board 132, and the heights of these electronic components 1321 are usually different. If the position where the power supply bin 114 is in contact with the power control circuit board 132 is a flat surface, the electronic components 1321 with lower heights on the power control circuit board 132 will not be able to contact the surface of the power supply bin 114, and the heat generated by them cannot be conducted through the wall of the power supply bin 114 to the first housing 110 for heat dissipation.

[0092] Therefore, in order to better conduct the heat generated by the power control circuit board to the first housing, in some embodiments of the present application, as Figure 3 and Figure 4 shown, a protrusion 1145 is formed on the surface of the power supply bin 114 facing the internal space of the first housing 110. The protrusion 1145 is in contact with the electronic components 1321 on the power control circuit board 132, so that the heat generated by the electronic components 1321 can be conducted through the wall of the power supply bin 114 to the first housing 110.

[0093] The height of the protrusion 1145 can be set according to the height of the electronic components 1321 in contact. Specifically, the height of the protrusion 1145 is opposite to the height of the electronic components 1321. For example, if the height of the electronic components 1321 is relatively high, the height of the protrusion 1145 needs to be set relatively low; if the height of the electronic components 1321 is relatively low, the height of the protrusion 1145 needs to be set relatively high. Of course, when the height difference between the highest electronic component 1321 and the lowest electronic component 1321 is relatively large, a groove can also be formed on the upper surface of the power supply bin 114. For example, a groove is provided at the position corresponding to the electronic components 1321 with relatively high heights, and the protrusion 1145 is only provided at the position corresponding to the electronic components 1321 with relatively low heights.

[0094] Furthermore, in order to further accelerate the heat dissipation speed of the power control circuit board, as Figure 3 and Figure 4As shown, heat dissipation teeth 133 can also be provided on the side of the power control circuit board 132 facing away from the power supply compartment 114 to increase the contact area between the power control circuit board 132 and the air, so as to prevent the electronic components 1321 on the power control circuit board 132 from overheating.

[0095] In the above embodiment, by providing the protrusion 1145 on the upper surface of the power supply compartment 114, the electronic components 1321 on the power control circuit board 132 are better attached to the surface of the power supply compartment 114, so that the heat generated by the electronic components 1321 can be better conducted to the first housing 110 for heat dissipation.

[0096] In order to improve the battery life of the navigation deception device, in some embodiments of the present application, such as Figure 5 As shown, a plurality of power supplies 131 are detachably installed in the power supply compartment 114, and the power control circuit board 132 is used to control the plurality of power supplies 131 to supply power in sequence. When a plurality of power supplies 131 are provided in the power supply compartment 114, an independent power control circuit board 132 can be provided for each power supply 131, and these power control circuit boards 132 are electrically connected to each other, so that each power control circuit board 132 can obtain the operating conditions of all the power supplies 131, and determine whether it is necessary to control the power supply 131 electrically connected to itself to supply power according to the operating conditions of other power supplies 131, thereby realizing that the plurality of power supplies 131 can supply power in sequence. With such a design, when one of the power control circuit boards 132 is damaged, the other power control circuit boards 132 can still normally control the power supplies 131 electrically connected to themselves to supply power. Of course, a common power control circuit board 132 can also be provided for the plurality of power supplies 131, and the power control circuit board 132 controls all the power supplies 131.

[0097] In the above embodiment, by providing a plurality of power supplies 131 in the power supply compartment 114 and having the power control circuit board 132 control the plurality of power supplies 131 to supply power in sequence, when one of the power supplies 131 is short of power and needs to be replaced, other power supplies 131 can be used to supply power to the navigation deception device 100, effectively improving the battery life of the navigation deception device 100 and solving the demand for the navigation deception device 100 to work with all-weather battery life.

[0098] In order to make the disassembly of the power supply more convenient, in some embodiments of the present application, such as Figure 5 and Figure 7As shown in the figure, an elastic member 1311 is provided on the power supply 131. The elastic member 1311 is configured to be deformed and generate an elastic force when the power supply 131 enters the power supply compartment 114 and is abutted by the opening 1142 of the power supply compartment 114. The elastic member 1311 is configured to be mutually pressed and fixed with the wall of the power supply compartment 114 under the action of the elastic force when the power supply 131 is electrically connected to the power supply control circuit board 132. The elastic member 1311 is further configured to move in the direction close to the power supply 131 and separate from the wall of the power supply compartment 114 when a pressure towards the power supply 131 is applied, so as to move the power supply 131 out of the power supply compartment 114.

[0099] As Figure 5 shown in the figure, the elastic member 1311 can be a spring piece provided on the side wall of the power supply 131 at one end facing the opening 1142. When installing the power supply 131, the power supply 131 can be fixed by the elastic force generated by the spring piece only by inserting the end of the power supply 131 without the spring piece into the power supply compartment 114. Specifically, during the insertion process, the wall at the opening 1142 will abut against the spring piece, causing the spring piece to approach the power supply 131 and generate an elastic force. When the power supply 131 is inserted in place (i.e., when the power supply 131 is electrically connected to the power supply control circuit board 132), the spring piece will press the wall of the power supply compartment 114 under the action of the elastic force to fix the power supply 131. When removing the power supply 131, only by applying a pressure greater than the elastic force to separate the spring piece from the wall of the power supply compartment 114, the power supply 131 can be withdrawn from the power supply compartment 114.

[0100] Of course, the elastic member 1311 can also be composed of a spring and a pressing portion. Specifically, one end of the spring can be fixedly connected to the power supply 131, and the other end can be fixedly connected to the pressing portion. When installing the power supply 131, the pressing portion is abutted by the opening 1142 and approaches the power supply 131, causing the spring to be compressed and generate an elastic force. The pressing portion can be a plate-like structure, so that the spring and the pressing portion form a structure similar to a spring piece.

[0101] In the above embodiments, the power supply 131 is fixed in the power supply compartment 114 by providing the elastic member 1311, so that when installing the power supply 131, the power supply 131 only needs to be inserted into the power supply compartment 114, and when removing the power supply 131, only a pressure needs to be applied to the elastic member 1311 to separate the elastic member 1311 from the wall of the power supply compartment 114. The installation and removal of the power supply 131 are more convenient.

[0102] According to another aspect of the embodiments of the present application, as Figure 1 shown in the figure, a drone countermeasure system is provided. The system includes a handheld anti-drone device 200 and the navigation deception device 100 described in any of the above embodiments. The handheld anti-drone device 200 is electrically connected to the power supply unit and the network interaction unit through cables respectively. The power supply unit is configured to supply power to the handheld anti-drone device 200, and the network interaction unit is configured to communicate with the handheld anti-drone device 200.

[0103] As Figure 4 shown, an interface 115 can be provided on the first housing 110, and the interface 115 is electrically connected to the power supply unit 130 or the network interaction unit 150. One end of a cable is electrically connected to the interface 115, and the other end is electrically connected to the handheld anti-drone device 200, so as to realize the electrical connection between the power supply unit 130 or the network interaction unit 150 and the handheld anti-drone device 200. Of course, when the interface 115 is an interface such as USB or Type-C that can perform data transmission and is suitable for charging, the interface 115 can also be electrically connected to both the power supply unit 130 and the network interaction unit 150 at the same time. Furthermore, only one cable is needed to connect the navigation spoofing device 100 and the handheld anti-drone device 200, so that the navigation spoofing device 100 can communicate with the handheld anti-drone device 200 while supplying power to the handheld anti-drone device 200.

[0104] It should be particularly noted that, in addition to the strike device described in the above embodiments, the handheld anti-drone device 200 can also be a detection device or a terminal device. Specifically, when the handheld anti-drone device is a detection device, when the handheld anti-drone device detects the navigation signal of the target drone, it can send the navigation signal to the network interaction unit 150 through a cable. The network interaction unit 150 sends the navigation signal to the navigation spoofing unit 140, so that the navigation spoofing unit 140 generates a navigation simulation signal and the antenna 170 emits the navigation simulation signal to spoof the target drone. In addition, when the navigation spoofing device 100 does not need to operate in cooperation with the handheld anti-drone device, the network interaction unit 150 can also be electrically connected to a terminal device with a display (such as a mobile phone, a tablet, a computer, etc.). The network interaction unit 150 analyzes the navigation signal and the navigation simulation signal to obtain information such as the position, flight altitude, and flight direction of the target drone, and then sends this information to the terminal device, so that the terminal device displays this information through the display, enabling the user to directly obtain relevant information about the target drone from the display of the terminal device.
