Embodiment 1

[0025] refer to figure 1 , shows a structural block diagram of a vehicle-mounted device according to Embodiment 1 of the present application.

[0026] The vehicle-mounted device in this embodiment includes a vehicle-mounted device body 102 and an anti-disassembly structure 104 .

[0027] Wherein, the anti-disassembly structure 104 includes a first electrode and a second electrode, and the first electrode and the second electrode form an equivalent capacitor, so that the anti-disassembly structure 104 becomes a capacitive induction type anti-disassembly structure. When the on-vehicle device is installed on the vehicle, the vehicle component to which the anti-disassembly structure 104 is bonded serves as the medium of the equivalent capacitor, and when it is not bonded, air can be used as the medium of the equivalent capacitor. When the medium between the first electrode and the second electrode changes, the capacitance between the first electrode and the second electrode chang...

Embodiment 2

[0032] The vehicle-mounted device in this embodiment includes a vehicle-mounted device body and a capacitive sensing anti-disassembly structure. In the following, the capacitive sensing type anti-disassembly structure will be introduced first.

[0033] refer to figure 2 , shows a side view of a capacitive sensing disassembly-preventing structure of a vehicle-mounted device according to Embodiment 2 of the present application.

[0034] As shown in the figure, the first electrode 1 and the second electrode 2 of the capacitive sensing anti-disassembly structure form an equivalent capacitance, which is pasted on the shell 4 of the vehicle-mounted device body through an adhesive medium, in this embodiment, double-sided tape 3 . Moreover, after the equivalent capacitor is pasted, there is still sufficient space for pasting on the pasting medium, so that the equivalent capacitor, that is, the capacitive sensing anti-disassembly structure can be pasted on the vehicle component.

Embodiment 3

[0057] refer to Figure 5 , shows a schematic structural diagram of a vehicle-mounted device according to Embodiment 3 of the present application.

[0058] The vehicle-mounted device in this embodiment includes a capacitive sensing anti-disassembly structure 302 and a vehicle-mounted device body 304 .

[0059] Wherein, the capacitive sensing type anti-disassembly structure 302 includes a first electrode 3022 and a second electrode 3024, the first electrode 3022 and the second electrode 3024 can adopt the comb electrode in the second embodiment, and interleave according to the method in the second embodiment Arrangement, any other suitable electrodes can also be used and arranged accordingly. When the in-vehicle device is installed or removed, the capacitance between the first electrode 3022 and the second electrode 3024 changes.

[0060] The capacitive sensing anti-disassembly structure 302 is arranged on the outer side of the vehicle-mounted device body 304 by means of doub...

Abstract

The invention provides a vehicle-mounted device which comprises a vehicle-mounted device body and an anti-dismantling structure, wherein the anti-dismantling structure comprises a first electrode and a second electrode, and the first electrode and the second electrode form an equivalent capacitor. When the vehicle-mounted device is installed on a vehicle, a vehicle part which is attached to the anti-dismantling structure serves as a medium of the equivalent capacitor. The vehicle-mounted device body and the anti-dismantling structure are in an integrated structure. A capacitive detection device is arranged to detect change of capacitance of the equivalent capacitor when the vehicle-mounted device is installed on the vehicle. Through the vehicle-mounted device, the effects of improving sensitivity of the anti-dismantling structure of the vehicle-mounted device, avoiding misoperation to the vehicle-mounted device or preventing the vehicle-mounted device from being illegally used, and improving use experience by users are achieved.

Description

technical field [0001] The present application relates to the field of microwave communication, in particular to a vehicle-mounted device. Background technique [0002] ETC (Electronic Toll collection, electronic toll collection system) means that when the vehicle passes through the toll station, it realizes vehicle identification and information writing through OBU (On-Board Unit, on-board equipment), and automatically collects the information from the pre-bound IC card or bank account. Deducting corresponding funds is an electronic toll collection system for roads, bridges and tunnels that is being developed and popularized internationally. [0003] The ETC system is composed of background system, lane controller, RSU (Road-SideUnit, roadside unit) and OBU. Among them, the lane controller, RSU and OBU form the ETC front-end system to realize the control, identification and charging of passing vehicles in the lane; the back-end system is connected to the service network fo...
