[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4 As shown, a portable countermeasure device for GPS spoofing drones includes a drone body 1. A mounting plate 2 is fixedly connected to the bottom of the drone body 1. T-shaped grooves are provided on both sides of the front of the mounting plate 2, and T-shaped sliders 3 are slidably connected inside the T-shaped grooves. A countermeasure device body 12 is fixedly connected to the bottom of the T-shaped sliders 3. Through-holes 4 are opened on the front and rear sides of both sides of the mounting plate 2. Insertion slots 5 are opened on the surface of the T-shaped sliders 3. Insert rods 6 are slidably connected inside the through-holes 4 and are inserted into the insertion slots 5. Tension springs 7 are fixedly connected to the front and rear sides of both sides of the mounting plate 2. A movable plate 8 is fixedly connected to the side of the tension springs 7 away from the mounting plate 2. The insert rods 6 are fixedly connected to the movable plate 8.

[0021] refer to Figure 2 The back of the movable plate 8 is fixedly connected to the first movable frame 9 and the second movable frame 10 respectively. The surfaces of the first movable frame 9 and the second movable frame 10 are fixedly connected with teeth. The number of teeth is several. The bottom of the UAV body 1 is rotatably connected to the gear 11, which meshes with the teeth. The first movable frame 9 and the second movable frame 10 are both L-shaped.

[0022] As a technical optimization of this utility model, through the arrangement of the first movable frame 9, the second movable frame 10, the gear 11, and the teeth, for example, when the operator pulls the left movable plate 8 to the left, it drives the first movable frame 9 to the left, and then drives the gear 11 to rotate through the teeth on the surface of the first movable frame 9. The gear 11 drives the second movable frame 10 to move to the right through the teeth on the surface of the second movable frame 10. With this arrangement, the operator does not need to use both hands to pull the movable plates 8 on both sides away from each other. The operator only needs to pull the movable plate 8 on one side to move away from the mounting plate 2, which will drive the movable plate 8 on the other side to move away from the mounting plate 2.

[0023] refer to Figure 4 The front of the T-shaped slide bar 3 is fixedly connected to a connecting strip 14, which is attached to the mounting plate 2. The surface of the connecting strip 14 is provided with bolts 15, which are threadedly connected to the mounting plate 2.

[0024] As a technical optimization of this utility model, by setting up the connecting strip 14 and the bolt 15, after the operator installs the T-shaped slide bar 3, the connecting strip 14 is in contact with the mounting plate 2. The operator can use the bolt 15 to install the connecting strip 14 to the mounting plate 2, thereby reinforcing the T-shaped slide bar 3. This application only sets up one bolt 15, and the operator only needs one matching tool to quickly install and remove the bolt 15. The operator can determine whether to install the bolt 15 according to the actual use scenario of the device.

[0025] refer to Figure 2 The bottom of the drone body 1 is fixedly connected with a protective frame. There are several protective frames, which are fixedly connected to the mounting plate 2. The protective frames are evenly distributed on the bottom of the drone body 1.

[0026] As a technical optimization of this utility model, the protective frame can, to a certain extent, prevent the first movable frame 9, the second movable frame 10, or the gear 11 from being damaged by impact.

[0027] refer to Figure 2 The bottom of the drone body 1 is provided with a sliding groove, and a slider is slidably connected inside the sliding groove. The slider is fixedly connected to the movable plate 8.

[0028] As a technical optimization of this utility model, by setting up the slide groove and the slider, the slider can slide stably left and right in the slide groove, thereby enabling the movable plate 8 to slide stably left and right, and enabling the insertion rod 6 to move stably left and right, thus improving the stability of the device.

[0029] refer to Figure 3 The surface of the tension spring 7 is coated with anti-rust paint, and the movable plate 8 is fixedly connected to the side away from the mounting plate 2 with a handle 13.

[0030] As a technical optimization of this utility model, by spraying anti-rust paint on the surface of the tension spring 7, the tension spring 7 can be prevented from being corroded, thereby improving the service life of the device. The handle 13 makes it easy for the operator to hold the handle 13 and then pull the movable plate 8 to move away from the mounting plate 2.

[0031] The working principle and usage process of this utility model are as follows: During use, for example, when the operator needs to disassemble the countermeasure device body 12, the operator pulls any one of the movable plates 8 to move it away from the mounting plate 2, thereby moving the insertion rod 6 until the insertion rod 6 separates from the insertion port 5. Through the arrangement of the first movable frame 9, the second movable frame 10, the gear 11, and the teeth, for example, if the operator pulls the left movable plate 8 to the left, it moves the first movable frame 9 to the left, and the teeth on the surface of the first movable frame 9 drive the gear 11 to rotate. The gear 11, through the teeth on the surface of the second movable frame 10, drives the second movable frame 10 to the right. With this setting, the operator does not need to use both hands to pull the movable plates 8 on both sides away from each other. The operator only needs to pull the movable plate 8 on one side away from the mounting plate 2 to move the movable plate 8 on the other side away from the mounting plate 2. At this time, the insert rods 6 on both sides and the movable plates 8 move away from each other. At this time, the tension spring 7 is stretched, and the insert rods 6 on both sides separate from the inserts 5 on the surface of the T-shaped slide bar 3, thereby releasing the lock on the T-shaped slide bar 3. Then the operator pulls the T-shaped slide bar 3 in front until the T-shaped slide bar 3 separates from the T-shaped slide groove, thereby completing the disassembly of the T-shaped slide groove and the countermeasure device body 12.

[0032] The countermeasure device body 12 includes a shell, a GPS spoofing module, a control module, a power module, and an antenna, etc.

[0033] The GPS spoofing module generates fake GPS signals to deceive the GPS positioning system of the target drone. This module includes a signal generation unit and a signal modulation unit. The signal generation unit can generate different types of fake GPS signals according to preset parameters, such as fake location information and speed information; the signal modulation unit modulates the generated fake signals to conform to the GPS signal transmission standard. A control module is connected to the GPS spoofing module and is used to control the operating mode and parameter settings of the GPS spoofing module. The control module includes a microprocessor and a user interface. The microprocessor uses a high-performance single-chip microcomputer, capable of quickly processing various instructions and data; the user interface uses a touchscreen design for convenient operation and settings. Users can select different spoofing modes through the user interface, such as fixed-point spoofing and trajectory spoofing, and set corresponding parameters, such as spoofing position and spoofing time. The power module provides power support for the entire device, including a rechargeable battery and power management circuitry. The rechargeable battery uses a high-capacity lithium battery, which has the advantages of small size, light weight and long flight time; the power management circuit can manage the charging of the battery and monitor the power level to ensure the stable operation of the device. The above-mentioned UAV body 1 and countermeasure device body 12 are common existing technologies and are common knowledge to those skilled in the art, and will not be described in detail in this application.
