[0035] Embodiment

[0036] Please see Figure 1 and Figure 2 The embodiment provides an arm shield type unmanned aerial vehicle countermeasure device, which comprises a countermeasure shield shell 100, a control circuit board 200, an antenna 300 and at least two power amplifier modules 400, and the control circuit board 200, the antenna 300 and the at least two power amplifier modules 400 are arranged in the countermeasure shield shell 100.

[0037] Among them, at least two power amplifier modules 400 are electrically connected with the control circuit board 200, and the electromagnetic wave frequency bands of the at least two power amplifier modules 400 are different from each other.

[0038] The antenna 300 is electrically connected with the at least two power amplifier modules 400, and is used for radiating electromagnetic wave signals from the at least two power amplifier modules 400 at the same time.

[0039] When the above-mentioned arm-shield type unmanned aerial vehicle countermeasure device is used, the control circuit board 200 controls the at least two power amplifier modules 400 to be turned on at the same time, and the antenna 300 radiates electromagnetic wave signals of at least two different frequency bands at the same time, so as to realize multi-frequency suppression, cut off the signal link between the unmanned aerial vehicle and the remote controller, and force the unmanned aerial vehicle to return, land or hover. Therefore, the above-mentioned arm-shield type unmanned aerial vehicle countermeasure device can effectively cope with the frequency modulation communication technology of the unmanned aerial vehicle, and the operator does not need to frequently manually switch the interference mode, so that the disposal efficiency is higher.

[0040] Please refer to Figure 2 In some embodiments, the power amplifier module 400 includes a 1.5G power amplifier module 410, a 2.4G power amplifier module 420, a 5.2G power amplifier module 430, and a 5.8G power amplifier module 440.

[0041] It can be understood that the 1.5G power amplifier module 410, the 2.4G power amplifier module 420, the 5.2G power amplifier module 430, and the 5.8G power amplifier module 440 are respectively electrically connected with the control circuit board 200 and the antenna 300. Accordingly, the antenna 300 adopts a four-in-one antenna 300.

[0042] When used, the antenna 300 can emit strong electromagnetic waves matched with the communication frequency bands (such as 2.4G / 5.8G, 5.2G, GPS / Beidou, etc.) of the unmanned aerial vehicle, so as to realize multi-frequency suppression.

[0043] Please refer to Figure 2 In some embodiments, the above-mentioned arm-shield type unmanned aerial vehicle countermeasure device further includes a cooling fan 500, and the cooling fan 500 is arranged in the countermeasure shield shell 100.

[0044] When used, the built-in cooling fan 500 can effectively dissipate heat, reduce the heating problem of the power amplifier module 400 working for a long time, and prolong the continuous operation time of the entire arm-shield type unmanned aerial vehicle countermeasure device.

[0045] Please refer to Figure 2 Further, the above-mentioned arm-shield type unmanned aerial vehicle countermeasure device further includes a cooling plate 600, and the cooling plate 600 is arranged in the countermeasure shield shell 100.

[0046] Correspondingly, the at least two power amplifier modules 400 are in contact with one side surface of the cooling plate 600, and the cooling fan 500 is located on the other side of the cooling plate 600.

[0047] In use, the heat generated by the power amplifier modules 400 is directly transferred to the heat sink 600. At the same time, the heat dissipation fan 500 drives air flow. The air carries away the heat on the heat sink 600 when flowing through the surface of the heat sink 600, and the heat sink 600 cooperates with the power amplifier modules 400 to achieve efficient heat dissipation.

[0048] Specifically, the heat sink 600 is in the shape of a cuboid. The 1.5G power amplifier module 410, the 2.4G power amplifier module 420, the 5.2G power amplifier module 430, and the 5.8G power amplifier module 440 are in contact with one side surface of the heat sink 600 along the thickness direction and are arranged along the length direction of the heat sink 600. The heat dissipation fan 500 is located at the other side of the heat sink 600 along the thickness direction.

[0049] In addition, the control circuit board 200 is located on the same side of the heat sink 600 as the power amplifier modules 400, and the antenna 300 is located on the side of the control circuit board 200 and the power amplifier modules 400 away from the heat sink 600.

[0050] It can be understood that the internal components of the countermeasure shield shell 100 are designed reasonably and arranged compactly, which can reduce the self-weight of the entire arm shield type unmanned aerial vehicle countermeasure device. In addition, the main part of the arm shield type unmanned aerial vehicle countermeasure device is made of engineering plastics and other composite materials, and the overall mass is not greater than 5 kg, which is convenient for carrying.

[0051] In contrast, the weight of the existing countermeasure shield generally exceeds 5 kg, and long-time handheld can cause fatigue, which has great limitations in fast and mobile application scenarios.

[0052] For example, the countermeasure shield shell 100 is provided with an air inlet hole and an air outlet hole. The heat dissipation fan 500 sucks external air into the inside of the countermeasure shield shell 100 through the air inlet hole and discharges internal air to the outside of the countermeasure shield shell 100 through the air outlet hole, so that the air circulates and dissipates heat.

[0053] Please refer to Figure 1 and Figure 3 In some embodiments, the countermeasure shield shell 100 has a radiation surface 110 and a wearing surface 120 opposite to each other. The radiation surface 110 is in the shape of a plane. The wearing surface 120 is in the shape of a concave curve, and the wearing surface 120 is provided with a handle 130.

[0054] The handle 130 is designed in a streamline shape, cooperates with the concave wearing surface 120 to accommodate the arm of the operator, is convenient for the operator to grip and hold the countermeasure shield shell 100, and conforms to ergonomics. The operator can hold the shield with one hand to interfere with the flight navigation link, remote control signal, and image transmission signal of the unmanned aerial vehicle.

[0055] Further, the handle 130 is located at one end of the wearing surface 120, and the middle part of the wearing surface 120 is further provided with an elastic bandage 140.

[0056] When the above-mentioned arm-shield type UAV countermeasure device is worn, the operator binds the elastic bandage 140 on the arm, which can share part of the weight to the arm, relieving the hand fatigue.

[0057] In some embodiments, the first launch switch 150 and the second launch switch 160 are arranged on the countermeasure shield shell 100 and are electrically connected with the control circuit board 200 respectively.

[0058] The control circuit board 200 controls the power amplifier module 400 to radiate the first electromagnetic wave signal through the antenna 300 when the first launch switch 150 is pressed, and the first electromagnetic wave signal is used to make the UAV return. The control circuit board 200 controls the power amplifier module 400 to radiate the second electromagnetic wave signal through the antenna 300 when the second launch switch 160 is pressed, and the second electromagnetic wave signal is used to make the UAV crash.

[0059] In use, the operator can select the countermeasure mode according to the actual situation and press the first launch switch 150 or the second launch switch 160 to make the UAV return or crash.

[0060] Exemplarily, the first launch switch 150 and the second launch switch 160 are arranged on the handle 130. In addition, the first launch switch 150 and the second launch switch 160 are both self-locking switches. After the countermeasure is completed, the operator presses the first launch switch 150 or the second launch switch 160 again to reset them.

[0061] In some embodiments, the power supply external interface 170 is arranged on the countermeasure shield shell 100 and is electrically connected with the control circuit board 200.

[0062] Correspondingly, the above-mentioned arm-shield type UAV countermeasure device further comprises a battery box 700 and a spring power line 800, and the battery box 700 is detachably connected with the power supply external interface 170 through the spring power line 800.

[0063] In use, the spring power line 800 is used to connect the power output port of the battery box 700 with the power supply external interface 170 on the countermeasure shield shell 100, so that the battery box 700 can supply power to the control circuit board 200, the cooling fan 500 and each power amplifier module 400.

[0064] The battery box 700 is independently designed, which can be worn by the operator, further reducing the volume of the countermeasure shield shell 100, reducing the weight of the handheld component and relieving the fatigue of the operator.

[0065] In addition, the spring power line 800 is freely extendable and will not hinder the operator during operation and movement.

[0066] Exemplarily, the length of the counter-shield shell 100 is 315 mm, the width is 195 mm, and the height is 125 mm. The length of the battery box 700 is 155 mm, the width is 95 mm, and the height is 65 mm.

[0067] Exemplarily, threaded caps are arranged at the joints of both ends of the spring power line 800, so as to be screwed with the battery box 700 or the counter-shield shell 100, and to ensure that the spring power line 800 is not easily loosened or dropped during movement.

[0068] Exemplarily, the battery box 700 is provided with a power switch 710, and the operator controls the power on and off by pressing the power switch 710.

[0069] Correspondingly, the counter-shield shell 100 is provided with a power indicator 180. When the operator presses the power switch 710 and controls the power on, the power indicator 180 lights up, indicating that the control circuit board 200 has been powered on.

[0070] Exemplarily, the battery box 700 is provided with a power display 720. When the power is insufficient, the operator can check the power through the power display switch: once the power display switch is pressed, the power display light is on, and after a delay of 10-15 s, it is automatically turned off.

[0071] In some embodiments, the battery box 700 is provided with a first hook 730.

[0072] In use, the operator can hang the battery box 700 on the waist through the first hook 730, so as to carry it.

[0073] In some embodiments, the battery box 700 is provided with a second hook 740, and the counter-shield shell 100 is provided with a third hook 190, and the second hook 740 is clamped with the third hook 190.

[0074] In addition to carrying the battery box 700, the operator can also hang the second hook 740 on the third hook 190, so as to hang the battery box 700 and the counter-shield shell 100 together for use. Thus, the battery box 700 and the counter-shield shell 100 are detachably connected, and the protection and convenience can be considered.

[0075] Exemplarily, in use, an operator first takes the above-mentioned arm-shield type unmanned aerial vehicle countermeasure device from the transport box, and connects the power output port of the battery box 700 with the power external interface 170 on the countermeasure shield shell 100 by using the spring power line 800. Then, the operator holds the handle 130 on the countermeasure shield shell 100 with the left hand, and hangs the battery box 700 on the waist by the first hook 730, and binds the elastic bandage 140 on the arm. Then, the operator presses the power switch 710, aims the radiation surface 110 of the countermeasure shield shell 100 at the unmanned aerial vehicle, and presses the corresponding launch switch according to the countermeasure mode. At this time, the cooling fan 500 and each power amplifier module 400 inside the countermeasure shield shell 100 are started simultaneously, multi-frequency signals are sent through the antenna 300, the remote control and navigation signals of the unmanned aerial vehicle are interfered, and the unmanned aerial vehicle is forced to land or return. After the operation is completed, the operator presses the launch switch again to reset the launch switch, and finally turns off the power switch 710.

[0076] In summary, the above-mentioned arm-shield type unmanned aerial vehicle countermeasure device can radiate electromagnetic wave signals of multiple different frequency bands through the antenna 300 at the same time, realize multi-band suppression, cut off the signal link between the unmanned aerial vehicle and the remote controller, and force the unmanned aerial vehicle to return, land or hover. Therefore, the above-mentioned arm-shield type unmanned aerial vehicle countermeasure device can effectively cope with the frequency modulation communication technology of the unmanned aerial vehicle, and the operator does not need to frequently manually switch the interference mode, and the disposal efficiency is higher.

[0077] In all the examples shown and described herein, any specific values should be interpreted as merely exemplary and not as a limitation, and thus other examples of the example embodiments can have different values.

[0078] It should be noted that similar reference numbers and letters refer to similar items in the following drawings, and thus, once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings.

[0079] The above-mentioned embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
