[0025] 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.

[0026] Please see Figures 1-5 This utility model provides a technical solution: an anti-tampering device for a GPS positioning device, wherein an integrated circuit board 2 is provided inside the device housing 4, and a top plate 5 is also provided on the top of the device housing 4. The integrated circuit board 2 is installed inside the device housing 4 through a positioning structure. A magnet mounting structure 1 is also assembled inside the device housing 4, and the magnet mounting structure 1 is connected to the object being mounted.

[0027] The magnet mounting structure 1 includes a mounting box 11, a magnet block 12 is disposed inside the mounting box 11, and the mounting box 11 is disposed in the middle of the device housing 4.

[0028] A Hall sensor 7 is also integrated on one side of the integrated circuit board 2. The Hall sensor 7 is arranged perpendicular to the magnetic field of the magnet block 12. A GPS locator 3 is also installed on the integrated circuit board 2.

[0029] When using this device, firstly, the magnet mounting structure 1 is fixed to the object to be installed. Then, the device housing 4 is placed over the magnet mounting structure 1 and fixed to the object. The Hall sensor 7 on the integrated circuit board 2 monitors the magnetic field of the magnet block 12. When the device housing 4 is disassembled, it separates from the mounting box 11. The Hall sensor 7 detects the change in magnetic field and generates an alarm signal. After the alarm signal is processed by the processor, it is sent to the server through the communication module. The server receives and records the alarm information and can further trigger corresponding safety measures.

[0030] In this application, the Hall sensor 7 can sensitively detect changes in the magnetic field and eliminate errors caused by vehicle vibration through a built-in algorithm. The sensitivity and response speed of the Hall sensor 7 make it an ideal anti-tamper detection element. The fixed position design of the magnet block 12 takes into account various installation scenarios, ensuring stable detection performance under different installation positions and conditions. Compared to photosensitive sensors, the Hall sensor 7 used in this invention is unaffected by ambient light and can operate stably in low-light environments such as at night and in tunnels, without false alarms caused by direct sunlight or strong light. Furthermore, the signal processing module of the Hall sensor 7 can be seamlessly integrated with existing GPS positioning devices, and functional expansion can be achieved through simple software upgrades, greatly facilitating device upgrades.

[0031] Please see Figure 2 , Figure 5 as well as Figure 7 The positioning structure includes positioning sleeves 8, which are disposed on both sides of the integrated circuit board 2. The positioning sleeves 8 are snapped into the positioning grooves 22, which are disposed on one side of the support frame 23. The support frame 23 is disposed on both sides of the inner casing 4 of the device. During the installation of the integrated circuit board 2, the integrated circuit board 2 can be positioned and installed on the support frame 23. The integrated circuit board 2 is also provided with screw mounting holes 21 corresponding to the positioning sleeves 8 on both sides. The bottom of the positioning groove 22 is also provided with threaded holes 24 corresponding to the screw mounting holes 21, which can fix the integrated circuit board 2 to the support frame 23.

[0032] During the installation of integrated circuit board 2, the positioning sleeve 8 on integrated circuit board 2 is inserted into the positioning groove 22, and the integrated circuit board is attached to the support frame 23. Then, the locking bolt is passed through the bolt mounting hole through the positioning sleeve 8 and connected to the threaded hole 24, thereby installing integrated circuit board 2.

[0033] Please see Figure 3 , Figure 5 as well as Figure 6 A fixing plate 14 is provided on one side of the mounting box 11, which is connected to the object to be installed. Positioning blocks 13 are also provided on both sides of the mounting box 11. One end of the positioning block 13 is engaged in the positioning slot 42. The positioning slot 42 is provided on both sides of the mounting opening 41. The mounting opening 41 is provided at the bottom of the device housing 4, which can install the mounting box 11 inside the mounting box 11.

[0034] Install the fixing plate 14 on the object to be installed, then align the mounting port 41 on the device housing 4 with the mounting box 11, and make the positioning block 13 on the mounting box 11 snap into the positioning slot 42. When the mounting box 11 is fully inserted into the mounting port 41, the device housing 4 fits against the object to be installed, and at the same time, the magnet 12 is located directly below the Hall sensor 7, so that the magnet 12 can be hidden and installed inside the device housing 4.

[0035] Please see Figure 4 The mounting box 11 has symmetrically arranged grooves 16 on both sides. A plastic spring 17 is installed in the groove 16. One end of the plastic spring 17 is connected to the clamping plate 15. The clamping plate 15 is movably arranged in the groove 16. The clamping plate 15 clamps and fixes the magnet block 12 by the elastic force of the plastic spring 17. When the magnet block 12 is placed in the mounting box 11, the magnet block 12 simultaneously presses the two sets of clamping plates 15. The clamping plate 15 compresses the plastic spring 17. The plastic spring 17 uses its elastic force to stick the clamping plate 15 to the magnet block 12 and fix the magnet block 12.

[0036] Furthermore, a receiving groove is provided at the bottom of the mounting port 41, and the fixing plate 14 is placed in the receiving groove, which can hide the fixing plate 14 inside the bottom of the device housing 4, ensuring the flatness of the overall installation.

[0037] Furthermore, connecting plates 6 are provided on both sides of the device housing 4, which can fix the device housing 4 to the object being installed.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
