A magnetic generation anti-dismantlement component and a magnetic generation anti-dismantlement self-destruction device

Abstract

The invention provides a magnetic generator anti-dismantle assembly and a magnetic generator anti-dismantle self-destruction device, comprising: a rotating part 1, a magnetic core part 2, a coil part 3, a first elastic part 4, a second elastic part 5 and an anti-dismantle Rod 6; the rotating part 1 includes a hook plate 11, a pressing plate 12 and a rotating shaft 13, and the rotating shaft 13 is fixed on the magnetic core part 2 or the equipment to be installed; when the hook plate 11 engages the coil part 3, the first elastic part 4 is Stretching, and the anti-demolition rod 6 is against the pressure plate 12 under the action of external force, and makes the second elastic member 5 stretch under force; when the anti-demolition rod 6 loses the external force, the second elastic member 5 rebounds and pulls the pressure plate 12 Move towards the anti-demolition rod 6, and drive the hook plate 11 to rotate under the action of the rotating shaft 13, so that the coil part 3 is separated from the hook plate 11, and the coil part 3 slides under the action of the resilience of the first elastic part 4, and cuts the magnetic steel 21 The magnetic field lines generate electric current. With the present invention, tamper detection can be realized in the case of damaged or exhausted batteries.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a magnetic generation anti-disassembly assembly and a magnetic generation anti-disassembly self-destruction device. Background technique [0002] With the popularization of the non-parking toll collection electronic system ETC, the on-board unit installed on the vehicle side is widely used. At present, in order to avoid problems caused by the vehicle-mounted unit being disassembled from the vehicle window and then installed on other vehicles, it is necessary to install an anti-dismantle device (such as an anti-dismantle push switch) on the vehicle-mounted unit to detect whether the vehicle-mounted unit has been disassembled. Specifically, the existing vehicle-mounted unit is usually powered by a battery in the form of a storage battery, a rechargeable battery or a solar cell, and the chips of the vehicle-mounted unit are connected to the battery and the tamper switch respecti...

Problems solved by technology

[0003] However, because the battery may be damaged or the battery is exhausted, especially if the vehicle is parked in the underground parking lot for a long time, the solar battery cannot be charged and the battery is exhausted. In the case of battery damage or battery exhaustion, the chip of the on-board unit will be powered off , making it impossible to detect if the on-board unit has been removed

If the vehicle-mounted unit is disassembled, stolen, and reinstalled on the window when the power is off, since the anti-tamper switch is pressed again after reinstallation, the vehicle-mounted unit still cannot be detected even if the power is turned on or the battery is replaced. Has it been disassembled during a power outage?

Therefore, a new technology is urgently needed to solve the problem that the vehicle-mounted unit cannot detect whether it is disassembled when the power is off.
