Background technology
At present, using 5V standard USB as input module the power supply of household radio charge prepd more, and vehicle-mounted wireless charging product mostly is the 12V form directly inputted, these two kinds of charger interfaces are completely incompatible with voltage, this causes both exchange to use and all must be further provided with AC AC adapter or 12V turns the DC-DC blood pressure lowering adapter of 5V, the versatility of product is deteriorated so that user has to carry all kinds of adapter, thus causing the inconvenience in use.
The wireless charging module of 12V/5V dual input, it is exactly freeing user from complicated adapter, direct-connected 5V adapter charges the phone at home, the charging of cigar lighter 12V interface wireless is then directly inserted to car, the wired charge port of product of can also practicing midwifery carries out the current charges of maximum 5V/1.5A, it is achieved a tractor serves several purposes.
Utility model content
In order to solve the problems referred to above, this utility model provides a kind of supply module for onboard wireless charging, can freeing user from complicated adapter, direct-connected 5V adapter charges the phone at home, the charging of cigar lighter 12V interface wireless is then directly inserted to car, the wired charge port of product of can also practicing midwifery carries out the current charges of maximum 5V/1.5A, it is achieved a tractor serves several purposes.
Above-mentioned a kind of supply module for onboard wireless charging, including power input interface, buck management module, wireless charging management module, charge coil, Charge Management voltage reduction module and usb circuit；It is characterized in that, described power input interface includes 12V power input interface and 5V power input interface, described 12V power input interface and 5V power input interface and is connected with buck management module respectively；
Described buck management module is connected with charge coil by wireless charging management module, and described buck management module is connected with usb circuit also by Charge Management voltage reduction module.
In above-mentioned module, described 12V power input interface is magnetic-type interface.
In above-mentioned module, described 5V power input interface is Micro-USB interface.
Advantage of the present utility model and having the beneficial effects that: this utility model provides a kind of supply module for onboard wireless charging, possess two power input interfaces of 12V and 5V, make user at home or office can be directly connected to USB line be mobile phone charging, then can be directly connected to the charging of cigar lighter line onboard, and the fool proof measure of interface effectively can prevent user from mispluging interface line and cause that wireless charging device damages, it is achieved thereby that the compatibility of 2 kinds of voltage environment, the expense of buying adapter is saved for user, simplify user operation, avoid by the constraint of loaded down with trivial details adapter.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structured flowchart of supply module in this utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following example are only for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
As it is shown in figure 1, this utility model describes a kind of supply module for onboard wireless charging, including power input interface, buck management module 3, wireless charging management module 4, charge coil 5, Charge Management voltage reduction module 6 and usb circuit 7；
In order to meet domestic and automobile-used compatibility, the power input interface in this utility model includes 12V power input interface 1 and 5V power input interface 2, and 12V power input interface 1 manages module 3 with buck respectively with 5V power input interface 2 and is connected；Wherein, 12V power input interface 1 directly can connect the voltage within the scope of input 9～16V with cigar lighter line, 5V power input interface 2 then can directly insert connection standard USB line, adapts to the charging current of the repeatedly specification such as 5V (0.5A) to 5V (2.5A)；When connecting vehicle ignition electrical equipment 8 (vehicle-mounted 12V power supply), product realizes the 5W charging output of charge coil 5, also can meet the output requirement of the 5V (1.5A) of usb circuit 7 simultaneously.
When connecting domestic USB charging adapter 9 (the Micro-USB line of 5V), if source current is less than 5V (2.5A), then first meeting the output of the 5W of charge coil 5, remaining power reoffers 5V (electric current depend on dump power the number) output of usb circuit 7；If source current is less than 5V1.0A, then first ensureing the normal operation of charge coil 5, and limit output (now power is less than 5W), usb circuit 7 now then quits work, Non voltage output.
Preferably, in order to adapt to prior art, above-mentioned 12V power input interface 1 is magnetic-type interface, and 5V power input interface 2 is Micro-USB interface.
Meanwhile, buck management module 3 is connected with charge coil 5 by wireless charging management module 4, is thus configured to the Circuits System that wired charger 10 is charged；
Additionally, buck management module 3 is connected with usb circuit 7 also by Charge Management voltage reduction module 6, it is thus configured to the Circuits System that wireless charging device 11 is charged.
In this utility model, the operation principle of supply module is:
12V power input interface 1 manages module 3 with 5V power input interface 2 by same buck and suitable voltage inputs to wireless charging management module 4 and Charge Management voltage reduction module 6；
When the vehicle ignition electrical equipment 8 that input is 9～16V inputs, then voltage is maintained 12V and supplies wireless charging management module 4 by buck management module 3, and is depressurized to the 5V usb circuit 7 to wired charging circuit at another outfan；
When the USB charging adapter 9 that input is 5V inputs, then boost in voltage to 12V is supplied wireless charging management module 4 by buck management module 3, and the then voltage stabilizing of another outfan gives the usb circuit 7 of wired charging circuit to 5V；
Finally, wireless charging manage module 4 and drive charge coil 5, thus realizing wired charging transfer function；Meanwhile, another road is directly exported by usb circuit 7, thus realizing wireless charging transfer function.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
