Description

Technical Field

[0001] The utility model relates to the technical field of UAV interference, in particular to a radio device and a UAV interference device. Background Technique

[0002] In recent years, the rapid development of UAVs has given rise to many security problems. To ensure low-altitude safety, UAV interference devices are usually used to transmit radio frequency interference signals to interfere with the communication between UAVs and remote control terminals, so that UAVs can make an emergency landing or return automatically. However, due to the variety of UAVs, complex communication protocols, and non-uniform frequency bands, and the rapid upgrade and iteration speed of protocol anti-interference algorithms, the UAV interference device cannot achieve the expected interference effect. Therefore, the UAV interference device needs to have the ability to quickly iterate and upgrade.

[0003] The UAV interference device can use the SDR (Software Defined Radio) architecture to output interference signals. The SDR architecture supports software upgrade and iteration, and can adjust the interference signals specifically according to the UAV communication protocol without changing the hardware. The circuit of the SDR architecture includes a power amplifier unit and a control unit. If an independent SDR module is developed based on the SDR architecture, the power amplifier unit and the control unit need to be integrated in a housing. However, the power amplifier unit and the control unit will interfere with each other due to the reduced distance, affecting the normal operation of the SDR module. Summary of the Utility Model

[0046] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the detailed embodiments of the present utility model will now be described in detail with reference to the accompanying drawings.

[0047] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0048] In the description of the utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the utility model. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the utility model, unless otherwise specified, the meaning of "a plurality" is two or more.

[0049] In the description of the utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "joined", "provided in", "located in" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or a chemical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the utility model can be understood through specific circumstances.

[0050] It should be noted here that the "upper", "lower", "top", and "bottom" described below are all in the height direction Z of the housing 10.

[0051] As Figure 1 and Figure 2 shown, an embodiment of the present utility model discloses a radio device 1. For example, the radio device 1 is an SDR module. The radio device 1 includes a housing 10, a signal isolation board 12, a control unit 13, and a power amplifier unit 14, which are specifically as follows.

[0052] As Figure 5 shown, the signal isolation board 12 divides the interior of the housing 10 into a first cavity 101 and a second cavity 102 that are signal-shielded from each other. For example, the signal isolation board 12 is a plate made of a metal material (such as aluminum), which can provide good heat dissipation and signal shielding effects. The metal material (such as aluminum) here is only an example and does not limit this application.

[0053] The control unit 13 is used to generate radio frequency signals and is disposed within the first cavity 101. The power amplifier unit 14 is electrically connected to the control unit 13 to achieve signal transmission and power supply therebetween. The power amplifier unit 14 is used to amplify and output the radio frequency signals. The power amplifier unit 14 is disposed within the second cavity 102 to prevent mutual interference between the control unit 13 and the power amplifier unit 14 and ensure the normal operation of the radio device 1.

[0054] Among them, the control unit 13 includes, for example, a processor (such as an FPGA) and a transceiver. The processor is used to generate UAV interference source signals with different digital modulation methods, and the transceiver is used to modulate and convert the UAV interference source signals into radio frequency signals. The power amplifier unit 14 includes, for example, a power amplifier, which is used to amplify and output the radio frequency signals.

[0055] In this embodiment, the signal isolation board 12 shields the signals between the first cavity 101 accommodating the control unit 13 and the second cavity 102 accommodating the power amplifier unit 14, which can avoid the mutual interference between the control unit 13 and the power amplifier unit 14 resulting in the abnormal operation of the radio device 1.

[0056] In some embodiments, as Figure 2 shown, the control unit 13 and the power amplifier unit 14 are connected through a board-to-board connector (not shown). The signal isolation board 12 is provided with a connection opening 121 for the board-to-board connector to pass through. A gap may be left between the edge of the connection opening 121 and the outer peripheral wall of the board-to-board connector, or they may be tightly connected to ensure the signal shielding between the first cavity 101 and the second cavity 102. For example, the board-to-board connector may be a BTB connector, which has the advantages of small size and strong anti-interference ability. The BTB connector here is only an example and does not limit the present application.

[0057] In some embodiments, as Figure 4 and Figure 5 shown, the first cavity 101 and the second cavity 102 are stacked in the height direction Z of the housing 10. Compared with the arrangement of the first cavity 101 and the second cavity 102 in the length direction Y or the width direction X of the housing 10, the bottom area of the radio device 1 can be reduced, so as to facilitate the arrangement of a larger number of radio devices 1 on the installation part (not shown) of the UAV interference device, and thus more UAV frequency bands can be interfered.

[0058] In some embodiments, as Figure 2 and Figure 5 shown, the housing 10 includes an upper shell 103 and a bottom shell 104 with opposite openings in its height direction Z. The signal isolation board 12 is disposed between the upper shell 103 and the bottom shell 104.

[0059] Specifically, the edge of the upper surface of the signal isolation board 12 is connected to the opening edge of the upper shell 103, and a first cavity 101 is formed between the upper shell 103 and the upper surface of the signal isolation board 12.

[0060] The edge of the lower surface of the signal isolation board 12 is connected to the opening edge of the bottom shell 104, and a second cavity 102 is formed between the bottom shell 104 and the lower surface of the signal isolation board 12.

[0061] The upper shell 103 and the bottom shell 104 form the first cavity 101 and the second cavity 102 by sharing the signal isolation board 12. On the one hand, it can reduce the consumption materials of the radio device 1 and save costs. On the other hand, it can simplify the assembly process of the radio device 1 and improve production efficiency.

[0062] In some embodiments, the installation positions of each radio device 1 on the installation part of the UAV jamming device are preset. In order to enable the radio device 1 to be installed according to the preset positions, it is necessary to consider the problem that adjacent radio devices 1 interfere with each other due to process errors, resulting in the inability to install the radio device 1. Therefore, as Figure 3 shown, the length of the signal isolation board 12 is less than the length of the upper shell 103 and the bottom shell 104, and / or the width of the signal isolation board 12 is less than the width of the upper shell 103 and the bottom shell 104. After the signal isolation board 12, the upper shell 103 and the bottom shell 104 are assembled, it shows that the side edges of the signal isolation board 12 do not extend beyond the side walls of the upper shell 103 and the bottom shell 104 on the same side, so as to prevent interference between the radio devices 1 due to process errors and ensure that the radio device 1 can be successfully installed on the installation part of the UAV jamming device.

[0063] In some embodiments, as Figure 2 、 Figure 5 and Figure 6 shown, positioning posts 1041 are provided on the opening periphery of the bottom shell 104, positioning through holes 122 are provided on the signal isolation board 12, and the signal isolation board 12 is sleeved on the positioning posts 1041 of the bottom shell 104 through the positioning through holes 122 to realize the positioning of the signal isolation board 12 on the bottom shell 104, which is beneficial to reducing the assembly difficulty of the radio device 1.

[0064] Positioning counterbores 1031 are provided on the opening periphery of the upper shell 103, and the upper shell 103 is sleeved on the positioning posts 1041 of the bottom shell 104 through the positioning counterbores 1031 to realize the positioning of the upper shell 103 on the signal isolation board 12, which is beneficial to reducing the assembly difficulty of the radio device 1.

[0065] Understandably, the positioning posts 1041 can be one, two, three or any number. When the number of positioning posts 1041 is at least two, the signal isolation plate 12 and the upper shell 103 can be positioned and installed on the bottom shell 104 without rotation, so as to improve the positioning effect. Among them, different positioning posts 1041 can be arranged on different sides of the opening of the bottom shell 104. For example, one is arranged on the long side and one is arranged on the short side. If the wall thickness of the side wall of the upper shell 103 is not enough to open the positioning counterbore 1031, a clearance structure is provided at the position corresponding to the positioning post 1041 on the inner side of the side wall of the upper shell 103 to avoid interference with the positioning post 1041, but there is at least one positioning counterbore 1031 at the peripheral edge of the opening of the upper shell 103.

[0066] In some embodiments, such as Figure 2 , Figure 5 and Figure 8 shown, the radio device 1 further includes an isolation strip 17. For example, the isolation strip 17 is a strip made of a metal material (such as aluminum). The metal material (such as aluminum) here is only an example and does not limit the present application.

[0067] In the height direction Z of the housing 10, the bottom of the isolation strip 17 is connected to the side of the power amplifier unit 14 facing the signal isolation plate 12, and the top of the isolation strip 17 is connected to the signal isolation plate 12. In the length direction Y or width direction X of the housing 10, the opposite ends of the isolation strip 17 are connected to the opposite sides of the inner side wall of the bottom shell 104 to partition the space between the power amplifier unit 14 and the signal isolation plate 12, forming a plurality of functional areas that shield each other from signals. Among them, different electronic components (not shown) installed on the side of the power amplifier unit 14 facing the signal isolation plate 12 are accommodated in different functional areas to avoid interference between different electronic components.

[0068] And, as Figure 2 shown, a channel 171 for a connection line (not shown) to pass through is provided between the bottom of the isolation strip 17 and the power amplifier unit 14, and the connection line is used to connect the electronic components in different functional areas.

[0069] In some embodiments, such as Figure 5 , Figure 8 and Figure 9As shown, the inner top wall of the upper shell 103 protrudes towards the signal isolation board 12 to form a mounting step 1032. The side of the control unit 13 facing away from the signal isolation board 12 is mounted on the mounting step 1032 to be fixed within the upper shell 103. The mounting step 1032 leaves a space between the control unit 13 and the inner top wall of the upper shell 103 to accommodate electronic components (not shown) mounted on the side of the control unit 13 facing away from the signal isolation board 12. Generally, electronic components are not arranged at the edge of the board. Therefore, in this embodiment, the mounting step 1032 is formed at the connection between the inner top wall and the inner side wall of the upper shell 103, and the edge of the side of the control unit 13 facing away from the signal isolation board 12 is mounted and fixed on the mounting step 1032 to facilitate leaving a mounting space and avoid interference between the mounting step 1032 and the electronic components of the control unit 13.

[0070] In some embodiments, such as Figure 8 and Figure 9 As shown, the upper shell 103 is a shell made of a heat-conducting material (such as a metal material), for example, the metal material is aluminum. The metal material (such as aluminum) here is only an example and is not a limitation to this application. The inner top wall of the upper shell 103 protrudes towards the signal isolation board 12 to form a heat dissipation convex portion 1033. The heat dissipation convex portion 1033 contacts the electronic components (such as chips) mounted on the side of the control unit 13 facing away from the signal isolation board 12. Since the upper shell 103 is made of a heat-conducting material and has good heat conductivity, it can help the electronic components on the control unit 13 dissipate heat and avoid overheating of the electronic components on the control unit 13. The contact between the heat dissipation convex portion 1033 and the electronic components on the control unit 13 includes direct contact or contact through heat dissipation silicone grease.

[0071] In some embodiments, such as Figure 9 As shown, the inner side wall of the upper shell 103 protrudes towards the inside of the upper shell 103 to form a first positioning convex portion 1034. The side wall of the control unit 13 is recessed towards the inside of the upper shell 103 at a position corresponding to the first positioning convex portion 1034 to form a first positioning concave portion 131. The first positioning convex portion 1034 and the first positioning concave portion 131 are in positioning cooperation to reduce the assembly difficulty between the control unit 13 and the upper shell 103 and improve the assembly efficiency of the radio device 1.

[0072] In some embodiments, such as Figure 5 、 Figure 8 and Figure 10As shown in the figure, the inner bottom wall of the bottom case 104 protrudes towards the signal isolation plate 12 to form a mounting rib 1042. The side of the power amplifier unit 14 facing away from the signal isolation plate 12 is mounted on the mounting rib 1042 to be fixed inside the bottom case 104. The mounting rib 1042 leaves a space between the power amplifier unit 14 and the inner bottom wall of the bottom case 104 to accommodate electronic components (not shown) mounted on the side of the power amplifier unit 14 facing away from the signal isolation plate 12. Since the isolation strip 17 mounted on the power amplifier unit 14 is made of metal and has a relatively large weight, in this embodiment, the mounting rib 1042 is not only provided at the connection between the inner side wall and the inner bottom wall of the bottom case 104, but also is provided corresponding to the position of the isolation strip 17 to disperse the force on the power amplifier unit 14 and prevent the power amplifier unit 14 from being bent and damaged due to excessive local force.

[0073] A clearance groove 1043 is formed between the mounting ribs 1042 to leave an installation space for the electronic components mounted on the side of the power amplifier unit 14 facing away from the signal isolation plate 12. At least one clearance groove 1043 may be provided with heat dissipation silicone grease in contact with the electronic components mounted on the side of the power amplifier unit 14 facing away from the signal isolation plate 12 to help the power amplifier unit 14 dissipate heat.

[0074] In some embodiments, as Figure 10 shown, a second positioning convex portion 1044 is formed by the inner side wall of the bottom case 104 protruding towards the inside of the bottom case 104. The side wall of the power amplifier unit 14 is recessed towards the inside of the bottom case 104 at a position corresponding to the second positioning convex portion 1044 to form a second positioning concave portion 141. The second positioning convex portion 1044 and the second positioning concave portion 141 are in positioning cooperation to reduce the assembly difficulty of the power amplifier unit 14 and the bottom case 104 and improve the assembly efficiency of the radio device 1.

[0075] In some embodiments, in order to reduce the requirements for spare parts of the radio device 1, the radio device 1 is provided with a hollowed-out structure at the assembly part with a thickness greater than a preset value, so that standard-length screws can be used for assembly without the need to customize screws with a specific length.

[0076] As Figure 1 and Figure 7 shown, four top corners of the side walls of the bottom case 104, the signal isolation plate 12 and the upper case 103 are provided with first hollowed-out portions 18. At the bottom of the four top corners of the outer side wall of the bottom case 104, first mounting plates 1045 are provided corresponding to the positions of the first hollowed-out portions 18. Mounting holes (such as screw holes) are provided on the first mounting plates 1045. The radio device 1 can be mounted on the mounting part of the UAV jamming device through the mounting holes on the first mounting plates 1045 of the bottom case 104.

[0077] As Figure 1 and Figure 9As shown, at the position on the outer wall of the upper shell 103 corresponding to the first positioning convex part 1034, a second hollowed-out part 19 is formed by hollowing inward into the upper shell 103. At the bottom of the outer wall of the upper shell 103 corresponding to the position of the second hollowed-out part 19, a second mounting plate 1035 is provided, and the upper shell 103 is mounted on the signal isolation plate 12 through the second mounting plate 1035.

[0078] In some embodiments, usually one radio device 1 interferes with one frequency band. However, since the drone has a large number of frequency bands, to achieve the effect of interfering with different frequency bands simultaneously, multiple radio devices 1 are usually cascaded, and different radio devices 1 are made to interfere with different frequency bands. Therefore, the radio device 1 further includes a first electrical interface, and the first electrical interface is electrically connected to the control unit 13. The first electrical interface is used to realize the connection between different radio devices. For example, the first electrical interface includes an input interface 15 and an output interface 16. The input interface 15 and the output interface 16 are provided on the housing 10 and are electrically connected to the control unit 13, and are used to facilitate the signal input and output between different radio devices 1. For example, specifically: the output interface 16 of the first radio device 1 is electrically connected to the input interface 15 of the second radio device 1, and the output interface 16 of the second radio device 1 is electrically connected to the input interface 15 of the third radio device 1. Here, the first, second, and third radio devices 1 are only examples and do not limit the present application.

[0079] In some embodiments, such as Figure 1 and Figure 7 As shown, the radio device 1 further includes a second electrical interface, and the second electrical interface is electrically connected to the power amplifier unit 14. For example, the second electrical interface includes an input / output control interface 21, a power input interface 20, and an antenna interface 22. The input / output control interface 21, the power input interface 20, and the antenna interface 22 are provided on the housing 10 and are electrically connected to the power amplifier unit 14. The input / output control interface 21 is used to transmit signals for controlling the power amplifier unit 14, the power input interface 20 is used to supply power to the power amplifier unit 14, and the antenna interface 22 is used to connect an external antenna to the power amplifier unit 14.

[0080] Among them, the input interface 15 and the output interface 16 can be specifically provided on the upper shell 103, and the power input interface 20, the input / output control interface 21, and the antenna interface 22 can be specifically provided on the bottom shell 104. And the input interface 15, the output interface 16, the power input interface 20, and the input / output control interface 21 can be located on the same side of the radio device 1, which is convenient for the connection wiring between multiple radio devices 1 to be tidy, and the antenna interface 22 can be located on the side of the radio device 1 opposite to the other four interfaces.

[0081] An embodiment of the present utility model discloses a drone interference device, which includes a mounting part and at least one radio device 1 described in any of the above embodiments. The radio device 1 is mounted on the mounting part, and the radio device 1 will not be elaborated here.

[0082] In some embodiments, the drone interference device includes at least two radio devices 1 that interfere with different frequency bands. The at least two radio devices 1 are electrically connected through an input interface 15 and an output interface 16. It can be understood that the at least two can be two, three, or any number. Specifically, the drone interference device further includes a controller (not shown). The controller is electrically connected to the input interface 15 of the first radio device. The output interface 16 of the first radio device is electrically connected to the input interface 15 of the second radio device. The output interface 16 of the second radio device is electrically connected to the input interface 15 of the third radio device, and so on. Here, the first, second, and third radio devices 1 are only examples and do not limit the present application.

[0083] By implementing the present utility model, the following beneficial effects are achieved:

[0084] In the present utility model, the signal isolation plate 12 enables signal shielding between the first cavity 101 accommodating the control unit 13 and the second cavity 102 accommodating the power amplifier unit 14, which can prevent the control unit 13 and the power amplifier unit 14 from interfering with each other and causing the radio device 1 to malfunction.

[0085] It can be understood that the above embodiments only represent some implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, the above embodiments or technical features can be freely combined, and several deformations and improvements can also be made.
