Description
Technical field
The utility model relates to a kind of vehicle carried electronic label wireless charging device, and the mode of wireless charging can be adopted to charge to vehicle carried electronic label battery.
Background technology
Vehicle carried electronic label generally adopts 3.7V high-performance lithium battery, and service time is generally at about 2 years.Because vehicle carried electronic label is fixed on vehicle, do not allow privately to dismantle, the maintenance agency that changing battery after dead battery capability needs to specify is dismantled again, very inconvenient.For this reason; a lot of producer is all proposed the vehicle carried electronic label of solar recharging; adopt rechargeable type lithium ion battery+high light type solar recharging module; to extend the life-span of electronic tag; but by (microwave window place, electronic tag installation site; logical light rate variance) and the medium factor in garage that is parked in for a long time without sunlight of vehicle affect; often cause the serious power shortage of electronic tag; so vehicle carried electronic label is usually also furnished with charging wire; because different automobile types installation site is different; charging wire can be caused to be interfered, cannot charge in some vehicle.
Utility model content
The utility model, for the problems referred to above, provides a kind of vehicle carried electronic label wireless charging device, solves after label installs and activate, because of battery recharge difficulty, and the little and problem that causes vehicle carried electronic label useful life short of the subsidiary charging wire scope of application.
Described vehicle carried electronic label wireless charging device comprises wireless transmission unit, radio receiving unit and battery;
The resonant circuit that described wireless transmission unit comprises aerial coil, operating frequency is 13.56MHz and adaptor power supplies interface, resonant circuit input is connected with adaptor power supplies interface, and resonant circuit output is connected with aerial coil by cable;
Described radio receiving unit comprises inside tags coil and the inside tags charging circuit of vehicle carried electronic label self, and inside tags coil is connected with inside tags charging circuit, and inside tags charging circuit is connected with battery.
Described aerial coil is distributed on pcb board, and pcb board and vehicle carried electronic label high frequency card card interface match.
Described resonant circuit is close range wireless communication module.
Vehicle carried electronic label wireless charging device described in the utility model, make full use of the existing parts of vehicle carried electronic label, the inside tags coil of himself and inside tags charging circuit are used as radio receiving unit, only increase wireless transmission unit in outside, by the existing card interface of vehicle carried electronic label high frequency card during use, the aerial coil of wireless transmission unit is inserted this interface, and the aerial coil of wireless transmission unit and the inside tags coil of radio receiving unit are charged the battery by the mode of closely electromagnetic coupled.This wireless charging device have convenient, flexible, applicability is strong, with low cost, area is small and exquisite, high reliability.

Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
Vehicle carried electronic label wireless charging device described in the utility model, as shown in Figure 1, 2, comprises wireless transmission unit, radio receiving unit and battery 9;
It should be noted that, this vehicle carried electronic label wireless charging device need use the inside tags coil 7 of vehicle carried electronic label 6 self due to radio receiving unit, therefore the resonant operational frequency of wireless transmission unit need match with the operating frequency of vehicle carried electronic label, ensures as 13.56MHz.
The resonant circuit 3 that described wireless transmission unit comprises aerial coil 1, operating frequency is 13.56MHz and adaptor power supplies interface 4, resonant circuit 3 input is connected with adaptor power supplies interface 4, and resonant circuit 3 output is connected with aerial coil 1 by cable 5;
Described radio receiving unit comprises inside tags coil 7 and the inside tags charging circuit 8 of vehicle carried electronic label 6 self, and inside tags coil 7 is connected with inside tags charging circuit 8, and inside tags charging circuit 8 is connected with battery 9.
Further, aerial coil 1 is distributed on pcb board 2, and pcb board 2 and vehicle carried electronic label 6 high frequency card card interface match.
Further, in described vehicle carried electronic label wireless charging device, resonant circuit 3 is close range wireless communication module: i.e. NFC module, close range wireless communication module input is connected with adaptor power supplies interface, and close range wireless communication module output is connected with aerial coil 1 by cable 5.
With reference to shown in Fig. 3, during charging, the aerial coil 1 of wireless transmission unit is inserted vehicle carried electronic label 6 high frequency card card interface, again the adaptor power supplies interface 4 of wireless transmission unit is connected with automotive interior power supply, electric energy is through resonant circuit 3, preferably, pass through close range wireless communication module, radiate with electromagnetic energy by aerial coil 1, the inside tags coil 7 of radio receiving unit responds to this field energy by electromagnetic coupled mode, again by the shaping voltage stabilizing of crossing inside tags charging circuit 8 of warp, be finally delivered to battery 9, battery 9 is charged.
Above section Example of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
