For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0048] In order to achieve the coverage and strike of the existing drone countermeasure gun on the new frequency band, the present application proposes an independent power amplifier device. The independent power amplifier device increases the strike frequency band of the drone countermeasure gun by being detachably electrically connected to the antenna and the gun body of the drone countermeasure gun respectively, so that the existing drone countermeasure gun can meet the coverage and strike of the new frequency band.

[0049] On this basis, in order to make the independent power amplifier device easy to carry for mobile strike operations, corresponding straps are designed on the device body of the power amplifier device to achieve detachable fixation of the power amplifier device and the drone countermeasure gun. Specifically, the power amplifier device is tied and fixed to the butt of the drone countermeasure gun by the strap, so that it can move with the drone countermeasure gun while not affecting the operation of the drone countermeasure gun by technicians and ensuring the smooth progress of the strike operation.

[0050] According to one aspect of the embodiments of the present application, a power amplifier device is proposed. The power amplifier device is applied to a drone countermeasure gun. For details, please refer to Figure 1 and Figure 2 , Figure 1 shows the structure of the drone countermeasure gun to which the power amplifier device is applied, Figure 2 and

[0051] First, as shown in Figure 1 , the drone countermeasure gun 500 to which the power amplifier device 100 is applied includes a gun body 300 and an antenna device 200 provided on the gun body 300. The tail end of the gun body 300 has a butt 310.

[0052] Please further combine with Figure 2 , the power amplifier device 100 includes a device body 110 and a strap 120. Among them, the device body 110 is used to be detachably electrically connected to the gun body 300 and the antenna device 200 respectively. In the specific implementation shown in the figure, a first plug-in interface 111 and a second plug-in interface 112 can be provided on the device body 110. The first plug-in interface 111 is connected to the interface at the bottom of the handle 320 of the gun body 300 through a plug-in first cable 330 to realize the electrical connection between the device body 110 and the gun body 300. The second plug-in interface 112 is connected to the interface on the antenna device 200 through a plug-in second cable 210 to realize the electrical connection between the device body 110 and the antenna device 200. In addition to providing plug-in interfaces on the device body 110, cables can also be directly integrally fixed on the device body 110 and led out. During use, by plugging the connectors at the ends of the cables into the interfaces on the gun body 300 and the antenna device 200 respectively, the power amplifier device 100 is electrically connected to the gun body 300 and the antenna device 200.

[0053] For the fixation of the power amplifier device 100 on the gun body 300, please continue to combine with Figure 1 and Figure 2 , as shown in the figure, one side of the device body 110 is used to abut against one side of the gunstock 310. A binding part 113 is provided on the device body 110. The strap 120 is connected to the binding part 113 and is used to wind and fix on the gunstock 310 to fix the device body 110 to the gunstock 310. In the specific implementation shown in the figure, two straps 120 with one wide and one narrow are provided. By winding and fixing the two straps 120 on the gunstock 310 respectively, the stability of the power amplifier device 100 installed on the gun body 300 is ensured.

[0054] In the power amplifier device 100 provided by the embodiment of the present application, the device body 110 is detachably electrically connected to the gun body 300 and the antenna device 200 of the unmanned aerial vehicle countermeasure gun 500 respectively, so as to amplify the radio frequency signal of the new frequency band and output it through the antenna device 200, so that the unmanned aerial vehicle countermeasure gun 500 can increase new strike frequency bands and meet the strike requirements for different frequency bands of unmanned aerial vehicles. Further, considering that the independent power amplifier device 100 will affect the mobile strike operation of the unmanned aerial vehicle countermeasure gun 500, a binding part 113 is also provided on the device body 110 to connect the strap 120. Furthermore, the device body 110 can be conveniently fixed to one side of the gunstock 310 through the strap 120, so that the device body 110 moves with the gun body 300 and does not affect a series of operations of the technician on the gun body 300.

[0055] It should be noted that if the technician holds the gun with the right hand, the device body 110 is preferably as Figure 1It is fixed to the right side of the gunstock 310 as shown in the figure, so that the device body 110 is located on the outside and will not interfere too much with the human body. On the contrary, if the technician holds the gun with the left hand, the device body 110 is preferably fixed to the left side of the gunstock 310. In addition, if the upper and lower side areas of the gunstock 310 are large enough, the device body 110 can also be fixed to the upper or lower side of the gunstock 310.

[0056] In order to adapt to gunstocks 310 of different sizes, the present application further proposes an implementation manner. For details, please refer to Figure 3 , which shows the structure of one side view of the power amplifier device 100. As shown in the figure, the binding part 113 includes a first binding frame 1131 and a second binding frame 1132 arranged on opposite sides of the device body 110. The first end 121 of the binding strap 120 is fixed to the first binding frame 1131, and the second end 122 passes around the second binding frame 1132 and is detachably connected to the middle part 123 of the binding strap 120.

[0057] When fixing the device body 110 to the gunstock 310, first place one side of the device body 110 against one side of the gunstock 310. Then, after passing the second end 122 of the binding strap 120 around the gunstock 310 first, pass it through the second binding frame 1132, wrap it around the second binding frame 1132 and tighten it, so that the device body 110 tightly abuts against the gunstock 310. Finally, detachably fix the second end 122 to the middle part 123 of the binding strap 120, and the device body 110 can be stably installed on the gunstock 310, and the entire installation operation is convenient and fast.

[0058] For gunstocks 310 of different sizes, it is only necessary to tighten the binding strap 120 according to its size and fix the second end 122 at an appropriate position.

[0059] For the detachable fixing structure between the second end 122 and the middle part 123 of the binding strap 120, the present application further proposes an implementation manner. Specifically, the second end 122 of the binding strap 120 is detachably connected to the middle part 123 of the binding strap 120 by at least one of Velcro, buckle, hook and magnet.

[0060] In Figure 3 the specific embodiment shown, the second end 122 is detachably fixed to the middle part 123 by Velcro. Velcro can not only fix the second end 122 at any position on the middle part 123, but also bend and deform with the second end 122 and the middle part 123, ensuring that the binding strap 120 can tightly wrap around the gunstock 310.

[0061] For the fixing methods of buckles, hooks or magnets, multiple ones are generally arranged at different positions of the middle part 123 of the strap 120 to ensure that when cooperating with gun stocks 310 of different sizes, the second end 122 can be connected and fixed to different positions of the middle part 123. At the same time, since the buckles, hooks or magnets cannot deform with the strap 120, on the basis of ensuring the connection stability, the volume of a single one should be as small as possible to prevent the buckles, hooks or magnets from coming off during the process of the strap 120 bending and winding around the gun stock 310.

[0062] In addition to the way that the strap 120 provided in the above embodiment uses the movable second end 122 to bypass and fix to the second binding frame 1132, the strap 120 can also adopt an elastic band with both ends fixed to the device body 110. After stretching and relaxing the strap 120, it can be smoothly put on the gun stock 310. After releasing the strap 120, the strap 120 elastically retracts by itself and tightly fits on the gun stock 310 to fix the device body 110. Further, the strap 120 can also adopt an annular elastic band. Correspondingly, the binding part 113 can be a through hole opened on the device body 110, and the strap 120 is threaded through the through hole. By putting the strap 120 on the gun stock 310, the device body 110 can be stably fixed to the gun stock 310.

[0063] For the heat dissipation of the power amplifier device 100, the present application further proposes a structural design. For details, please refer to Figure 4 and Figure 5 , which respectively show the exploded structures of the power amplifier device 100 from two perspectives in the figure. As shown in the figure, the device body 110 includes a housing 114, a power amplifier module 115 and a heat dissipation component 116. One side of the housing 114 is used to abut against one side of the gun stock 310, and the binding part 113 is arranged on the housing 114. Both the power amplifier module 115 and the heat dissipation component 116 are arranged inside the housing 114.

[0064] The heat dissipation component 116 includes a radiator 1161 and an air flow driving component 1162. One side of the radiator 1161 is attached to the power amplifier module 115, and the other side is provided with heat dissipation teeth 11611. The radiator 1161 is used to conduct the heat of the power amplifier module 115 to the heat dissipation teeth 11611. Specifically, the radiator 1161 can adopt a structure with good thermal conductivity such as a copper block or an aluminum block, and the heat dissipation teeth 11611 are integrally formed on the radiator 1161.

[0065] The air flow driving component 1162 is disposed at at least one end of the heat dissipation fins 11611. Ventilation holes 1141 are formed in the housing 114 at positions opposite to both ends of the heat dissipation fins 11611. The air flow driving component 1162 is configured to drive air flow through the heat dissipation fins 11611 via the ventilation holes 1141, so that the air flow takes away the heat of the heat dissipation fins 11611. The air flow driving component 1162 can be a single fan disposed only at one end of the heat dissipation fins 11611 as shown in the figure. Of course, it can also be multiple fans disposed at one end of the heat dissipation fins 11611 or multiple fans disposed at both ends of the heat dissipation fins 11611.

[0066] The power amplifier module 115 is a component with a relatively large heat generation inside the housing 114. For its heat dissipation principle, please refer to Figure 6 , as shown by the solid arrows in the figure, the heat generated by the power amplifier module 115 is transferred by the radiator 1161 to the heat dissipation fins 11611. The air flow driving component 1162 then drives the air flow through the channels between the heat dissipation fins 11611 as shown by the dashed arrows in the figure, thereby taking away the heat on the heat dissipation fins 11611 and achieving efficient heat dissipation for the power amplifier module 115.

[0067] In order to further improve the heat dissipation efficiency of the power amplifier module 115, the present application also proposes an implementation manner. Specifically, please refer to Figure 4 , as shown in the figure, a wind guide cover 1142 is provided on the inner wall of the housing 114 around the ventilation holes 1141. The wind guide cover 1142 is used to guide the air flow through the heat dissipation fins 11611.

[0068] Specifically, in the Figure 4 shown specific embodiment, the wind guide cover 1142 covers the outer ends of the heat dissipation fins 11611 and the outer ends of the air flow driving component 1162 respectively, so as to enclose the gaps between the inner wall of the housing 114 and the heat dissipation fins 11611 and between the inner wall of the housing 114 and the air flow driving component 1162 as much as possible, ensuring that the air flow entering and leaving through the ventilation holes 1141 flows through the heat dissipation fins 11611 as much as possible, so as to take away more heat on the heat dissipation fins 11611 and achieve more efficient heat dissipation for the power amplifier module 115.

[0069] Furthermore, as shown in Figure 4 and Figure 5 , in order to ensure the reliability of the internal environment of the housing 114, a dust-proof net 1143 is further provided inside the ventilation holes 1141 to prevent as much as possible foreign dust and other impurities from entering the inside of the housing 114 and affecting structures such as the power amplifier module 115 and the air flow driving component 1162.

[0070] To reduce the weight of the power amplifier device 100 and thus facilitate the carrying and operation of technicians when fixing the power amplifier device 100 to the UAV countermeasure gun 500, the present application further proposes an implementation manner. Specifically, the power amplifier device 100 is used to obtain power from the gun body 300 for operation.

[0071] Since the electronic components in the power amplifier device 100 need power supply for operation, and for the scenarios of outdoor operation and mobile operation of the UAV countermeasure gun 500, only a mobile power supply can be used for power supply, such as a battery, etc. The setting of the battery will inevitably increase the weight of the power amplifier device 100, and thus increase the load of technicians.

[0072] Based on this, in this embodiment, the power amplifier device 100 does not have a built-in battery itself, but is detachably electrically connected to the gun body 300 to obtain power from the gun body 300 for operation, thereby reducing the weight of the power amplifier device 100 and making the UAV countermeasure gun 500 with the power amplifier device 100 fixed more portable.

[0073] When adding a new strike frequency band to the UAV countermeasure gun 500, in order to ensure that the antenna device 200 can adapt to the power amplifier device 100 of the new frequency band, according to another aspect of the embodiments of the present application, a wireless radio frequency device is also provided. Specifically, please refer to Figure 1 again, and further in combination with Figure 7 Figure 7 The structure of the wireless radio frequency device is shown. As shown in the figure, the wireless radio frequency device 400 includes an antenna device 200 and the power amplifier device 100 provided in any of the above embodiments. The antenna device 200 is detachably fixed to the gun body 300. The device body 110 of the power amplifier device 100 is detachably fixed to the gunstock 310 through a strap 120. The device body 110 is detachably electrically connected to the antenna device 200, and the device body 110 is also used to be detachably electrically connected to the gun body 300.

[0074] Specifically, the antenna device 200 can be detachably connected to the gun body 300 by means of snap connection, threaded connection, clamping fixation, etc.

[0075] In the wireless radio frequency device 400 provided by the embodiments of the present application, the supporting power amplifier device 100 and antenna device 200 cooperate with the gun body 300 of the UAV countermeasure gun 500 together to update the strike frequency band of the UAV countermeasure gun 500 and meet the strike requirements of different frequency bands.

[0076] Finally, the embodiments of the present application also provide a UAV countermeasure gun. Specifically, please refer to Figure 1 again. The UAV countermeasure gun 500 includes a gun body 300 and the wireless radio frequency device 400 provided in the above embodiments.

[0077] ​In the drone countermeasure gun 500 provided by the embodiments of the present application, the gun body 300 can cooperate with the external wireless radio frequency device 400 to work, increasing new strike frequency bands to meet the strike requirements for different frequency bands of drones.

[0078] To improve the stability of the installation of the power amplifier device 100 on the gunstock 310, the present application further proposes an implementation manner. For details, please refer to Figure 8 , which shows the structure of the power amplifier device 100 in the drone countermeasure gun 500 after the strap 120 is removed and exploded. As shown in the figure, a limiting groove 311 is provided on one side of the gunstock 310, and at least part of the device body 110 is received in the limiting groove 311 and one surface abuts against the bottom of the limiting groove 311.

[0079] Please further combine with Figure 9 the exploded state from another perspective in Figure 8 and Figure 9 In the specific embodiment shown, a boss 117 is provided on the device body 110 facing the gunstock 310. The boss 117 is received in the limiting groove 311, the top surface of the boss 117 abuts against the bottom of the limiting groove 311, and the periphery of the boss 117 is in limiting contact with the inner wall of the limiting groove 311. Of course, in some other embodiments, the boss 117 may not be provided on the device body 110, but the device body 110 itself is placed in the limiting groove 311, and the inner walls around the limiting groove 311 are in contact with the periphery of the device body 110 to limit the movement of the device body 110 on the gunstock 310.

[0080] In this embodiment, by providing the limiting groove 311 on the gunstock 310 to limit at least part of the device body 110 received in the limiting groove 311, after the device body 110 is fixed to the gunstock 310 by the strap 120, it is prevented that the device body 110 causes situations such as falling off due to relative displacement with the gunstock 310 under force, ensuring the stability of the installation of the device body 110 on the gunstock 310.

[0081] To further improve the connection stability between the device body 110 and the gunstock 310, the present application also proposes an implementation manner. For details, please refer to Figure 10 , which shows the three-dimensional structure of the drone countermeasure gun 500. As shown in the figure, a limiting protrusion 312 is provided on the gunstock 310, and the limiting protrusion 312 passes through the opening 124 on the strap 120.

[0082] In this embodiment, by passing the limiting protrusion 312 on the buttstock 310 through the opening 124 in the strap 120 and limiting the buttstock 312 by the inner walls around the opening, it can not only prevent the strap 120 from displacing along the extending direction of the gun body 300, but also prevent the strap 120 from rotating on the buttstock 310, thereby ensuring the stability of the installation and connection of the device body 110.

[0083] For the detachable connection structure between the antenna device 200 and the gun body 300, the present application further proposes an implementation manner, specifically as Figure 11 shown in the partial explosion structure in. A slide rail 340 is provided on the gun body 300, and a slide groove 220 is provided on the antenna device 200. The slide groove 220 is slidably matched with the slide rail 340. Please further combine Figure 12 with the partial enlarged structure in. As shown in the figure, a fixing block 230 is provided on one side of the slide groove 220, and a locking block 240 is slidably provided on the fixing block 230. The locking block 240 and the fixing block 230 are connected by a threaded fastener 250. When installing the antenna device 200, first slide the slide groove 220 into a predetermined position of the slide rail 340, and then rotate the threaded fastener 250 to move the locking block 240 along Figure 12 the direction of the dotted arrow on the locking block 240 in to clamp the slide rail 340, so that the antenna device 200 is fixed on the gun body 300. When disassembling the antenna device 200, loosen the threaded fastener 250 to release the clamping of the slide rail 340 by the locking block 240.

[0084] Furthermore, an elastic member 260 can also be abutted between the locking block 240 and the fixing block 230. When the threaded fastener 250 is loosened, the threaded fastener 250 will loosen the slide rail 340 under the elastic force of the elastic member 260, and the slide groove 220 can be disengaged from the slide rail 340 to remove the antenna device 200.
