In an alternative embodiment, the first elastic member 4 may be located on either side of the magnetic core part 2 or on the upper surface or the lower surface of the magnetic core part 2, as long as it is ensured that the first elastic member 4 is rebounded so as to smoothly carry the sliding of the coil part 3.

In another alternative embodiment, as shown in fig. 1, the first elastic member 4 may include a first spring 41 and a second spring 42; one end of the first spring 41 is fixed on the shell, and the other end of the first spring 41 is connected with the coil component 3; one end of the second spring 42 is fixed to the housing, and the other end of the second spring 42 is connected to the coil component 3. By providing two sets of springs, the stability of the coil component during sliding can be maintained.

In a preferred embodiment, the first spring 41 and the second spring 42 may be provided as conductive materials, the first spring 41 being electrically connected to one end of the winding wire 31, and the second spring 42 being electrically connected to the other end of the winding wire 31. The first spring 41 and the second spring 42 may serve as a conductive member for connecting the wire 31 and the chip, thereby realizing the electric power transmission. The first spring 41 and the second spring 42 are used for completing the transmission of the current, so that the material and the space can be saved. The first spring 41 and the second spring 42 may be directly connected to the winding 31, or a conductive sheet or a PCB may be disposed on the supporting frame 32, such that the first spring 41 and the second spring 42 are connected to the winding 31 through the conductive sheet or the PCB

One end of the second elastic component 5 is fixed on the shell, and the other end of the second elastic component 5 is connected with the pressing plate 12; specifically, the second elastic member 5 is used to connect the pressure plate 12, and the second elastic member 5 may be a spring or other elastic material, and is stressed by stretching the second elastic member 5. An alternative embodiment of the arrangement of the second elastic element 5 is shown in fig. 1.

The first end of the anti-dismantling rod 6 is contacted with the pressure plate 12, and the second end of the anti-dismantling rod passes through a through hole formed in the shell to be exposed; specifically, the anti-detaching rod can pass through a through hole formed in the housing to move, one end of the anti-detaching rod is used for abutting against the pressing plate 12, and the other end of the anti-detaching rod can penetrate out of the through hole. When the second end of the anti-dismantling rod 6 is in a natural non-extrusion state, the second end of the anti-dismantling rod 6 penetrates through the shell through the through hole, the pressing plate 12 naturally contacts the first end of the anti-dismantling rod 6, and the second elastic component 5 is in a natural non-extrusion state.

When the hook plate 11 is engaged with the coil component 3, the first elastic component 4 is stressed and stretched, and the second end of the anti-removal rod 6 pushes the first end to abut against the pressing plate 12 under the action of external force, so that the second elastic component 5 is stressed and stretched; specifically, when the magneto-electric power generation detachment prevention self-destruction type in-vehicle unit needs to be mounted on an external object, the magneto-electric power generation detachment prevention assembly is in a standby state, in the standby state, the first elastic member 4 is pulled to drive the coil member 3 to slide and engage with the hook plate 11, and since the rotating member 1 on which the hook plate 11 is located is fixed to the magnetic core member 2 or the housing, the engaging force applied by the hook plate 11 to the coil member 3 is balanced with the elastic force of the first elastic member 4. Then, a shell (generally, a back plate of the magnetic power generation anti-disassembly self-destruction vehicle-mounted unit) where a through hole of the magnetic power generation anti-disassembly self-destruction vehicle-mounted unit is located is attached to an external object, at the moment, the second end of the anti-disassembly rod 6 is extruded by the external object and penetrates through the through hole to be retracted inwards, the first end of the anti-disassembly rod 6 is pushed by a thrust force to push the pressing plate 12, so that the second elastic component 5 is driven by the pressing plate 12 to bear a force, at the moment, the extrusion force borne by the second end of the anti-disassembly rod 6 and the elastic force of the second elastic component 5 are balanced, and the magnetic power generation anti-disassembly self-destruction vehicle-mounted unit. For example, when the on-board unit for ETC charging is to be mounted on a vehicle, a housing of the on-board unit having a through hole of a tamper bar 6 is attached to a window glass, and the tamper bar 6 is pressed by the window glass, so that the on-board unit is maintained in a standby state.

When the second end of anti-detaching rod 6 loses the exogenic action, second elastomeric element 5 kick-backs pulling clamp plate 12 and moves towards the first end direction of anti-detaching rod 6 to it is rotatory to drive hook plate 11 under the effect of rotation axis 13, makes coil component 3 break away from hook plate 11, and coil component 3 slides under the effect of first elastomeric element 4 resilience power, and cuts the magnetic line of force of magnet steel 21 and produces the electric current. Specifically, when the magnetic power generation anti-detachment self-destruction vehicle-mounted unit is detached from the mounted external object, the second end of the anti-detachment rod 6 is no longer subjected to extrusion force, so that the elastic force of the second elastic component 5 no longer has countervailing balance force, the second elastic component 5 rebounds naturally, the pressing plate 12 is driven to extrude the first end of the anti-detachment rod 6, and the second end of the anti-detachment rod 6 is pushed to penetrate through the through hole of the housing. And because the pressing plate 12 rotates, under the action of the rotating shaft 13, the hook plate 11 also rotates to a certain degree, so that the coil component 3 is separated from the hook plate 11, and the coil component 3 rebounds at a high speed under the action of the rebounding force of the first elastic component 4, thereby driving the coil component 3 to slide and cut magnetic lines of force to generate current. After the coil component 3 acquires current, the chip of the on-board unit can detect the existence of the current, so that the fact that the anti-detaching rod 6 is touched can be detected, namely that the on-board unit is detached from an external object can be detected, and the anti-detaching function of the on-board unit is realized. For example, when the vehicle-mounted unit for ETC charging is illegally removed from the vehicle window glass, the anti-removal rod 6 loses the external force action, so that the magnetic power generation anti-removal assembly is triggered to cut magnetic force lines for power generation, and the chip with the self-destruction function is self-destroyed when the chip detects the current generated by the coil component (3).

The utility model provides a self-destruction formula mobile unit is prevented tearing open in magnetic power generation can prevent tearing open the pole through the detection and whether touched and detect this mobile unit and whether demolishd to realize the self-destruction of preventing tearing open of mobile unit. When the magnetic power generation anti-disassembly self-destruction vehicle-mounted unit detects that the unit is disassembled, a chip physical self-destruction program or a program for erasing chip data is started, so that lawless persons can not use the vehicle-mounted unit any more. In addition, because the magnetic power generation anti-dismantling self-destruction type vehicle-mounted unit provided by the embodiment can generate current at the moment of being dismantled, even if the battery of the vehicle-mounted unit is damaged or exhausted, the anti-dismantling self-destruction function of the vehicle-mounted unit is not influenced.

In an optional implementation of this embodiment, the magneto-electric tamper assembly further comprises: a microswitch (not shown in the figures); the micro switch is arranged on the rotating component 1 or the magnetic core component 2, and when the hook plate 11 is clamped with the coil component 3, the coil component 3 triggers the micro switch to be closed; or the micro switch is arranged on the coil component 3, and when the hook plate 11 is clamped with the coil component 3, the rotating component 1 or the magnetic core component 2 triggers the micro switch to be closed. By arranging the micro switch, a user can know whether the hook plate 11 is clamped in place with the coil component 3, the operation is ensured to be in place, and misoperation is prevented.
