It should be noted that when an element is expressed as "connected" to another element, it can be directly on the other element, or there may be one or several intermediate elements therebetween.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0055] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not used to limit the present application.

[0056] An embodiment of the present application provides an unmanned aerial vehicle (UAV) countermeasure device, which is a ground device applied to counter an illegally invaded or maliciously used UAV system.

[0057] Please refer to Figure 1 , the UAV countermeasure device 100 of an embodiment of the present application includes a device main body 10, a pan-tilt 20 and a support member 30. The device main body 10 is used to detect and counter UAVs, and outputs a pan-tilt 20 control signal during the detection and counter process. The pan-tilt 20 is connected to the device main body 10 and can drive the device main body 10 to rotate on at least two different axes. The pan-tilt 20 is used to receive the pan-tilt 20 control signal, drive the device main body 10 to aim at the detected UAV according to the pan-tilt 20 control signal, and supply power to the device main body 10. The support member 30 is detachably connected to the pan-tilt 20. The support member 30 is used to be erected on a support plane to support the device main body 10 and the pan-tilt 20, and can be re-erected at any position on the support plane.

[0058] The working principle of the drone countermeasure device 100 in this embodiment is as follows: The device main body 10 is integrated with functional modules for detecting and striking drones, and sends a pan-tilt 20 control signal to the pan-tilt 20 during the detection and striking process, so that the pan-tilt 20 drives the device main body 10 to align with the detected drone according to the pan-tilt 20 control signal, and performs countermeasure operations after aligning with the detected drone. The support structure adopts a support component 30 that is detachably connected to the pan-tilt 20. Compared with the handheld drone countermeasure device 100, it realizes 24-hour all-weather safe deployment. Exemplarily, the support component 30 and the pan-tilt 20 can be detachably connected through at least one connection method such as bolt connection, snap connection, hinge connection, etc. In addition, the so-called support plane in this embodiment is one of the ground, vehicle-mounted plane, ship-mounted plane, etc. The support component 30 can be re-erected at any position on the support plane, so that the drone countermeasure device 100 can be disassembled and redeployed, which is beneficial to improving the deployment flexibility of the drone countermeasure device 100 and is applicable to various application scenarios. Further, the drone countermeasure device 100 is also connected to an external power supply through the pan-tilt 20 and supplies power to the device main body 10, thereby simplifying the wiring operation between the device main body 10, the pan-tilt 20 and the external power supply.

[0059] It can be understood that in this embodiment, the pan-tilt 20 drives the device main body 10 to rotate on at least two different axes so that the device main body 10 aligns with the detected drone, making the countermeasure operation of the drone countermeasure device 100 more accurate. And through the re-erectable support component 30, the convenience and flexibility of the drone countermeasure device 100 in different scenarios are improved. Further, in this embodiment, the pan-tilt 20 also supplies power to the device main body 10, simplifying the wiring operation between the device main body 10, the pan-tilt 20 and the external power supply, thereby improving the deployment efficiency of the drone countermeasure device 100.

[0060] Exemplarily, the pan-tilt 20 control signal output by the device main body 10 is used to drive the pan-tilt 20 to drive the device main body 10 to align with the target drone and follow the target drone during the detection and striking process. Optionally, the support component 30 can adopt a tripod or a single straight-tube support frame, etc. For example, in this embodiment provided Figure 1 It is shown by taking the support component 30 as a tripod as an example. The length of any one of the support rods of the tripod can be adjusted, and all the support rods of the tripod can be gathered together when stored, and can be separated from each other when in use. It should be noted that the specific structural settings of the support component can be determined according to actual application requirements, and this embodiment does not limit this.

[0061] In some embodiments, the pan-tilt 20 adopts a multi-axis pan-tilt, which can rotate at least around the axes in the vertical direction and the horizontal direction, providing a wide range of movement in the vertical and horizontal directions, so that the drone countermeasure system can cover a larger spatial area.

[0062] Please refer to Figure 2 Figure 2 , in some embodiments, the device body 10 includes a detection antenna module 11, a strike antenna module 12, and a control circuit 13. The detection antenna module 11 is configured to acquire radio signals within a detection range and generate detection information based on the radio signals. The control circuit 13 is electrically connected to the detection antenna module 11 and is configured to analyze the detection information and generate a pan-tilt 20 control signal and a countermeasure electrical signal when it is determined based on the detection information that there is a drone within the detection range. The strike antenna module 12 is electrically connected to the control circuit 13 and is configured to transmit a countermeasure radio signal to the detected drone according to the countermeasure electrical signal.

[0063] It can be understood that the core components of the drone countermeasure device 100 include the detection antenna module 11, the strike antenna module 12, and the control circuit 13. These three parts cooperate with each other to achieve effective detection, tracking, and strike of illegally intruding or potentially threatening drones.

[0064] The detection antenna module 11 is a key detection element of the device. By receiving radio signals and cooperating with the control circuit 13, it searches for and locates the target drone. Once the communication signal or reflected echo emitted by the drone is received, the system can determine the presence of the drone and its approximate position information. The strike antenna module 12 is mainly responsible for performing interference or destruction tasks. When the control circuit 13 determines based on the detection result that countermeasures need to be taken against the drone, the strike antenna module 12 will transmit a high-intensity radio frequency signal to interfere with or cut off the communication link between the drone and its operation terminal, causing the drone to lose control, forcing it to land or unable to continue performing tasks, or taking over the target drone by means of sending spoofing signals, etc.

[0065] The control circuit 13 can process data from the detection antenna module 11, analyze the state of the drone in real time, and generate a corresponding pan-tilt 20 control signal accordingly. The pan-tilt 20 control signal is used to cause the pan-tilt 20 to adjust the orientation of the device body 10 to ensure that the strike antenna 124 can accurately aim at the target drone and implement a strike on the target drone by driving the strike antenna module 12.

[0066] Please refer to Figure 3, in some embodiments, the detection antenna module 11 includes a directional detection antenna 112 and an omnidirectional detection antenna 114. The directional detection antenna 112 is connected to the control circuit 13, and the directional detection antenna 112 is configured to generate first detection information based on radio signals. The omnidirectional detection antenna 114 is connected to the control circuit 13, and the omnidirectional detection antenna 114 is configured to generate second detection information based on radio signals. The control circuit 13 is configured to obtain communication analysis information and position information of the detected unmanned aerial vehicle according to the first detection information, generate a pan-tilt 20 control signal according to the position information, and obtain frequency band information of the detected unmanned aerial vehicle according to the second detection information, and generate a countermeasure electrical signal according to at least one of the communication analysis information and the frequency band information.

[0067] The unmanned aerial vehicle countermeasure device 100 of this embodiment can receive radio signals within a full 360-degree range through the omnidirectional detection antenna 114. When an unmanned aerial vehicle enters its coverage area, it can provide second detection information, which at least includes preliminary data such as the presence and intensity of the unmanned aerial vehicle signal. The control circuit 13 is connected to the omnidirectional detection antenna 114. By analyzing this preliminary detection information, the frequency band information of the unmanned aerial vehicle can be quickly obtained, that is, any unmanned aerial vehicle in any direction around can be detected in a timely manner, and the frequency of the remote control or navigation signal it uses can be determined. At this time, the control circuit 13 can transmit interference signals to the unmanned aerial vehicle through the strike antenna module 12, and the unmanned aerial vehicle cannot normally receive instructions, upload images or execute the preset flight plan. After losing effective control, the unmanned aerial vehicle may automatically land on the ground according to the preset safety strategy, or enter a hover state until the battery runs out and then fall, so as to achieve the purpose of safety control.

[0068] Among them, the omnidirectional detection antenna 114 of this embodiment adopts an omnidirectional detection antenna 114 with a horn-shaped structure. In other embodiments, the omnidirectional detection antenna 114 can also adopt other structures, which are not limited here.

[0069] Furthermore, the directional detection antenna 112 has a more accurate directionality. Once the omnidirectional detection antenna 114 determines the basic orientation of the unmanned aerial vehicle, the unmanned aerial vehicle countermeasure device 100 of this embodiment changes the orientation by controlling the pan-tilt 20, so that the directional detection antenna 112 focuses on the basic orientation of the unmanned aerial vehicle to perform more accurate tracking and data collection on the target unmanned aerial vehicle.

[0070] The directional detection antenna 112 referred to in this embodiment can be a multi-antenna system. For example, in this embodiment, multiple rod-shaped external antennas are used to form a directional antenna array, and the direction of the UAV is estimated by analyzing the differences (such as phase difference or time difference) of the signals received from different antennas. In other embodiments, the directional detection antenna 112 can use antennas of other shapes. Additionally, in other embodiments, the UAV countermeasure device 100 can utilize beamforming technology to dynamically adjust the receiving mode of the antenna array to better locate the signal source.

[0071] When the directional detection antenna 112 captures the UAV signal, it provides the first detection information. After the control circuit 13 analyzes the first detection information, it obtains more detailed communication content and high-precision position information, and drives the pan-tilt 20 to work according to the position information so that the strike antenna module 12 is aligned with the target UAV, and drives the strike antenna module 12 to emit interference signals or spoofing signals to the target UAV according to the analysis content to interfere with or take over the UAV.

[0072] Exemplarily, the communication content obtained by the UAV countermeasure device 100 after analysis includes the communication protocol used by the UAV, the telemetry data of the UAV, the unique identifier of the UAV, and the unique identifier of the remote control terminal associated with the UAV, etc. The UAV countermeasure device 100 performs processing such as determining the legality of the UAV's behavior according to the analyzed communication content, and performs corresponding countermeasure operations (such as interfering with communication, taking over control, or directly grounding) based on the processing results, which is also conducive to tracing the owner or operator of the UAV.

[0073] It can be understood that the UAV countermeasure device 100 in this embodiment adopts a combination of an omnidirectional detection antenna 114 and a directional detection antenna 112. The omnidirectional detection antenna 114 is used for frequency band confirmation, and the directional detection antenna 112 is combined for precise positioning and communication analysis, enabling the UAV countermeasure device 100 to have an efficient and comprehensive response ability, reducing the possibility of misjudgment and missed reporting.

[0074] Please review Figure 3 , in some embodiments, the control circuit 13 includes a detection control processing module 132, a whole machine control module 134, a strike power amplifier module 136, and a power transfer module 138.

[0075] Among them, the detection control processing module 132 is electrically connected to the directional detection antenna 112 and is used to obtain the communication analysis information and position information of the detected UAV according to the first detection information.

[0076] The whole machine control module 134 is electrically connected to the detection control processing module 132 and the pan-tilt 20 respectively, and is used to obtain the communication analysis information and position information, output a pan-tilt 20 control signal according to the position information, and output a countermeasure control signal according to the communication analysis information.

[0077] The strike power amplifier module 136 is electrically connected to the whole machine control module 134, the omnidirectional detection antenna 114, and the strike antenna module 12 respectively, and is used to obtain frequency band information according to the second detection information, and generate a countermeasure electrical signal according to at least one of the frequency band information and the countermeasure control signal.

[0078] The power supply transfer module 138 is electrically connected to the strike power amplifier module 136, the whole machine control module 134, and the pan-tilt 20 respectively, and is used to obtain the supply current of the pan-tilt 20 and convert it into a working current that meets the working requirements of the strike power amplifier module 136, the detection control processing module 132, and the whole machine control module 134.

[0079] It can be understood that the detection control processing module 132 is connected to the directional detection antenna 112 and is responsible for receiving and processing the first detection information from the unmanned aerial vehicle. This information includes the position information of the unmanned aerial vehicle and the communication protocol with the control terminal, etc. By analyzing these data, the system can understand the activity status and location of the unmanned aerial vehicle in real time.

[0080] The whole machine control module 134 obtains the communication analysis information and position information from the detection control processing module 132 on the one hand, and controls the movement of the pan-tilt 20 on the other hand. Exemplarily, the whole machine control module 134 calculates an appropriate pan-tilt 20 rotation instruction according to the position information to generate a pan-tilt 20 control signal, and at the same time generates a countermeasure control signal based on the communication analysis information. The countermeasure control signal includes a control instruction for the strike power amplifier module 136, a spoofing signal for simulating the control of the unmanned aerial vehicle, etc.

[0081] The strike power amplifier module 136 obtains frequency band information according to the second detection information and receives the countermeasure control signal of the whole machine control module 134. The strike power amplifier module 136 includes a spectrum analysis unit, a signal source, and a power amplifier. Exemplarily, when receiving the second detection information, the spectrum analysis unit determines the frequency band information in the second detection information, and based on the frequency band information, the signal source generates an interference signal of the corresponding frequency after being amplified by the power amplifier and transmits it to the unmanned aerial vehicle through the strike antenna module 12. Another example is that when receiving the first detection information, the strike power amplifier module 136 receives the countermeasure control signal generated based on the first detection information, amplifies the spoofing signal and transmits it to the unmanned aerial vehicle through the strike antenna module 12.

[0082] The power transfer module 138 realizes the power supply transmission between the device main body 10 and the pan-tilt 20, provides power support for the entire device main body 10, monitors and ensures the stable supply current of the pan-tilt 20, and supplies power to the strike power amplifier module 136 and the whole machine control module 134 respectively. In addition, the whole machine control module 134 is also responsible for supplying power to the detection control processing module 132 to ensure the normal operation of each component. Exemplarily, the power transfer module 138 includes a voltage conversion unit, a voltage stabilization unit, a power supply protection unit, etc. The voltage conversion unit is used to convert the supply voltage of the pan-tilt 20 into multiple voltages required by each module in the control circuit 13. The voltage stabilization unit is used to stabilize the working voltages of each module during the operation of the control circuit 13. The power supply protection unit is used to provide protection such as overcurrent, overvoltage, and short circuit to the device main body 10. Among them, the voltage conversion unit, the voltage stabilization unit, and the power supply protection power supply can adopt existing circuits, which are not limited here.

[0083] Please refer to Figure 4 and Figure 5 , in some embodiments, the strike antenna module 12 includes an antenna carrier board 122, and a strike antenna 124 is disposed on any one of the antenna carrier boards 122. When the number of antenna carrier boards 122 is multiple, the multiple antenna carrier boards 122 are spaced apart, and the transmission frequency bands of the strike antennas 124 between any two antenna carrier boards 122 are independent of each other.

[0084] It can be understood that the number of antennas of the strike antenna module 12 in this embodiment can be set according to actual needs. By deploying the antennas on the antenna carrier board 122, it is convenient for installation, disassembly, and replacement. When the number of antenna carrier boards 122 is at least two, the antenna carrier boards 122 are arranged at intervals to reduce the electromagnetic coupling influence between them and ensure the independence and effectiveness of the operation of each antenna. Further, for the strike antennas 124 on any two antenna carrier boards 122, the radio wave frequency bands they emit are independent of each other. This means that each antenna can operate within its designated frequency band without interference, so that precise strikes can be implemented simultaneously for different target frequency bands, improving the spectrum coverage range and interference effect of the system.

[0085] Please also refer to Figures 4 to 6 , in some embodiments, the device main body 10 further includes a base 14, a bracket assembly 15, and a first housing 16. The control circuit 13 is installed on the base 14. The bracket assembly 15 is connected to the base 14. The strike antenna module 12 is installed on the bracket assembly 15 and is isolated from the control circuit 13 and the detection antenna module 11 respectively. The detection antenna module 11 is installed on at least one of the base 14 and the bracket assembly 15. The first housing 16 is connected to the base 14 and the pan-tilt 20 respectively, and the first housing 16 and the base 14 together form a first receiving chamber 162, and the bracket assembly 15 and the control circuit 13 are both received in the first receiving chamber 162.

[0086] It can be understood that the device body 10 forms a first accommodation chamber 162 for accommodating the strike antenna module 12 and the control circuit 13 through the base 14 and the first housing 16. The detection antenna module 11 can also be accommodated in the first accommodation chamber 162, thereby protecting the control circuit 13 and each antenna module.

[0087] In some embodiments, a sealing ring 142 is provided at the connection between the base 14 and the first housing 16. When the base 14 and the first housing 16 are connected, the sealing ring 142 is squeezed to close the connection gap between the base 14 and the first housing 16, so as to improve the airtight performance and waterproof performance of the first accommodation chamber 162.

[0088] It can be understood that in rainy days or humid climates, due to the sealing ring 142 between the base 14 and the first housing 16 of the drone countermeasure device 100 in this embodiment, water vapor and rainwater are prevented from entering the first accommodation chamber 162 and damaging each antenna module and the control circuit 13.

[0089] Please refer to Figure 5 and Figure 6 , in some embodiments, the bracket assembly 15 includes a support cover plate 152, a top cover 154 and a support skeleton 156. The support cover plate 152 is fixedly connected to the base 14 and is located between the control circuit 13 and the strike antenna module 12 to isolate the control circuit 13 and the strike antenna module 12. The top cover 154 is fixedly connected to the support cover plate 152, and the detection antenna module 11 is installed on at least one of the top cover 154 and the base 14. The support skeleton 156 is fixedly connected to the support cover plate 152, and the strike antenna module 12 is installed on the support skeleton 156.

[0090] Optionally, the support cover plate 152 and the base 14 can be connected by bolts and nuts. The top cover 154 and the support skeleton 156 can be connected to the support cover plate 152 by bolts and nuts, or can be riveted or welded to the support cover plate 152 respectively.

[0091] In some embodiments, the support skeletons 156 are arranged in pairs at intervals. Each support skeleton 156 is provided with a chute. In a pair of support skeletons 156, the chutes on different support skeletons 156 are arranged oppositely. A pair of opposite sides of at least one antenna carrier plate 122 are respectively embedded in the chutes of a pair of support skeletons 156 and are located between the pair of support skeletons 156. Exemplarily, three antenna carrier plates 122 arranged at intervals are adopted in this embodiment. The antenna carrier plates 122 on both sides are installed by being embedded in the chutes of the support skeletons 156, and the antenna carrier plate 122 in the middle is connected to the support skeletons 156 by bolts and nuts and is installed.

[0092] It can be understood that the support framework 156 fixes the striking antenna module 12 in the first accommodation bin 162, and the support cover plate 152 separates the control circuit 13 and the striking antenna module 12 to avoid interference with the control circuit 13 when the striking antenna module 12 is operating. Further, the top cover 154 can also be used to install part of the detection antenna module 11, and at the same time separates the striking antenna module 12 and the detection antenna module 11 to avoid mutual interference between the antenna modules.

[0093] In one embodiment, the antenna carrier board 122 is installed on the support framework 156 at intervals, the omnidirectional detection antenna 114 is installed on the top cover 154, the directional detection antenna 112 uses an external antenna, and an antenna interface electrically connected to the control circuit 13 is provided on the base 14. The directional detection antenna 112 is connected to the antenna interface and is placed outside the device main body 10.

[0094] Please refer to Figure 6 and Figure 7 At the same time, in some embodiments, the base 14 is a metal structural member, and the base 14 includes a first mounting surface 144 and a second mounting surface 146 arranged opposite to each other. The device main body 10 further includes a heat dissipation component 17 and a second housing 18. The control circuit 13 is installed on the first mounting surface 144, and the heat dissipation component 17 is arranged on the second mounting surface 146. The second housing 18 is connected to the base 14 and jointly forms a second accommodation bin 182 with the base 14. The heat dissipation component 17 is accommodated in the second accommodation bin 182. Among them, the heat dissipation component 17 is used to dissipate heat from the base 14 and the second accommodation bin 182.

[0095] It can be understood that due to the heat generated by the transmission power of the striking antenna module 12 and the heat generated when the control circuit 13 is operating, heat accumulation exists in the first accommodation bin 162. When the temperature continues to rise, the working devices in the first accommodation bin 162 are likely to be unstable or malfunction due to the high temperature. Therefore, in this embodiment, a metal base 14, a heat dissipation component 17 and a second housing 18 are adopted, and the base 14 and the second housing 18 form a second accommodation bin 182 for accommodating the heat dissipation component 17. The heat in the first accommodation bin 162 will be conducted through the metal base 14 and dissipated by the heat dissipation component 17 in the second accommodation bin 182, so as to reduce the temperature in the first accommodation bin 162 and ensure the stable operation of the control circuit 13 and each antenna module.

[0096] Please refer to Figure 7 and Figure 8, in some embodiments, the heat dissipation component 17 includes a plurality of heat dissipation fins 172 and a heat dissipation fan 174. The plurality of heat dissipation fins 172 are arranged at intervals on the second mounting surface 146 of the base 14 to form a plurality of air ducts. The second housing 18 is provided with an air inlet 184 at one end of the air duct and an air outlet 186 at the other end of the air duct. The heat dissipation fan 174 is mounted on the second mounting surface 146 of the base 14 and is located on at least one air duct. The heat dissipation fan 174 is used to accelerate the gas flow in the air duct.

[0097] It can be understood that in this embodiment, a plurality of heat dissipation fins 172 are provided on the second mounting surface 146 of the base 14 to increase the heat dissipation area of the base 14, and a heat dissipation fan 174 is provided in a plurality of air ducts to increase the gas flow rate in the air ducts, thereby improving the heat dissipation efficiency.

[0098] In some embodiments, the plurality of heat dissipation fins 172 are integrally formed with the base 14. Since the hot air flow will gradually rise, the air inlet 184 of the second housing 18 is provided at the bottom, and the air outlet 186 is provided at the top.

[0099] Please review Figure 7 and Figure 8 , in some embodiments, the device main body 10 includes a data transmission interface 192 and a power transmission interface 196. The pan-tilt 20 includes a first connecting member 22, a pan-tilt main body 24, and a second connecting member 26. Among them, the data transmission interface 192 is electrically connected to the whole machine control module 134, and the power transmission interface 196 is electrically connected to the power conversion module 138.

[0100] The first connecting member 22 is connected to the device main body 10. The first connecting member 22 includes a first articulated arm 222 and a second articulated arm 224 arranged at intervals. The first articulated arm 222 is provided with a first lead portion 2222. The data transmission interface 192 is connected to the first lead portion 2222 through a data transmission cable 194. The second articulated arm 224 is provided with a second lead portion 2242. The power transmission interface 196 is connected to the second lead portion 2242 through a power transmission cable 198.

[0101] The pan-tilt main body 24 is located between the first articulated arm 222 and the second articulated arm 224. The first articulated arm 222 and the second articulated arm 224 are jointly articulated to the pan-tilt main body 24 around the same horizontal axis (A1). Both the first lead portion 2222 and the second lead portion 2242 are located on the horizontal axis. The pan-tilt main body 24 is connected to the data transmission interface 192 through the first lead portion 2222 and the data transmission cable 194, and is connected to the power transmission interface 196 through the second lead portion 2242 and the power transmission cable 198. The second connecting member 26, the second connecting member 26 is detachably connected to the support member 30. The pan-tilt main body 24 is articulated to the second connecting member 26 around a vertical axis (A2).

[0102] It can be understood that the pan-tilt main body 24 and the first connecting member 22 are hinged to each other about a horizontal axis, and are connected to the device main body 10 through the first connecting member 22, so as to realize the pitching motion of the device main body 10; the pan-tilt main body 24 of the pan-tilt 20 and the second connecting member 26 are hinged about a vertical axis, so that when the pan-tilt main body 24 rotates, it drives the device main body 10 to realize the rotation motion of the device main body 10. Further, the first connecting member 22 is provided with a first hinge arm 222 and a second hinge arm 224, and a first lead portion 2222 and a second lead portion 2242 are respectively provided on the first hinge arm 222 and the second hinge arm 224. The data transmission interface 192 of the device main body 10 will be connected to the pan-tilt main body 24 through the first lead portion 2222 and the data transmission cable 194 to realize data transmission between the device main body 10 and the pan-tilt main body 24. For example, the device main body 10 sends a pan-tilt 20 control signal to the pan-tilt main body 24.

[0103] Correspondingly, the power transmission interface 196 of the device main body 10 is connected to the pan-tilt main body 24 through the second lead portion 2242 and the power transmission cable 198 to realize power supply from the pan-tilt main body 24 to the device main body 10. Among them, since the first lead portion 2222 and the second lead portion 2242 are both located on the horizontal axis where the first connecting member 22 and the pan-tilt main body 24 are hinged, when the device main body 10 performs a pitching motion or a rotation motion, the data transmission cable 194 and the power transmission cable 198 will not be wound around the pan-tilt 20, which is beneficial to improving the reliability of the UAV countermeasure device 100.

[0104] In some embodiments, a connection support plate 226 is provided at the top of the first connecting member 22, a set of threaded holes are provided at the bottom of the first housing 16, and a set of screws that cooperate with the set of threaded holes are installed on the connection support plate 226, and are fixedly connected to the first housing 16 through the connection of the screws and the threaded holes.

[0105] In some embodiments, the device main body 10 further includes a wireless charging module. The wireless charging module is electrically connected to the control circuit 13. The wireless charging module includes a power receiving coil located at the bottom of the device main body 10. A power supply coil is provided at the top of the pan-tilt 20 and is aligned with the power receiving coil. The pan-tilt 20 forms an electrical connection loop through the power supply coil, so that the power supply coil supplies power to the power receiving coil. The wireless charging module obtains a supply current through the power receiving coil and supplies power to the control circuit 13.

[0106] It can be understood that through the above settings, the setting of the power transmission cable 198 can be reduced between the device main body 10 and the pan-tilt 20 to improve the installation and disassembly efficiency of the overall device.
