Circle) it is separated by plastic upper cover with RX coils (i.e. the coil of receiving terminal), or even also separated by filter band, TX coils have been elongated significantly
At a distance between RX coils, charge efficiency is reduced.
Invention content
The goal of the invention of the utility model, due to using plastic upper cover, is caused to solve on conventional wireless charger
TX coils and RX coil-spans be low from excessive, charge efficiency and the problem of having a single function of wireless charger itself.
To solve the above-mentioned problems, the utility model proposes a kind of wireless chargers, including pedestal, upper cover and TX lines
Circle further includes being set to external RX coils and vehicle-mounted receiving terminal；The upper cover is fixedly connected to form cavity with pedestal；It is described
TX coils are installed in the cavity, and electromagnetic coupling connects between the TX coils and RX coils；The upper cover is band filtering work(
Can pcb board, and the upper cover is connected by NFC communication between the vehicle-mounted receiving terminal.
Preferably, it is formed with copper foil on the pcb board；The copper foil is distributed in the pcb board surface in pectination, enables institute
The EMC for stating pcb board is improved.
Preferably, including NFC antenna；The NFC antenna is set on the pcb board, enables the pcb board and vehicle-mounted reception
End communication connection.
Preferably, the NFC antenna surround and is set at the outer of the pcb board；The copper foil is set in pcb board
At the heart.
From the foregoing, it will be observed that following advantageous effect can be obtained using the utility model：
First, the utility model uses the pcb board with filter function directly as the upper cover of wireless charger, to enable
Pcb board can improve the EMC of wireless charger itself, and high frequency electromagnetic wave signal is filtered, and then reduce the spoke of wireless charger
The influence penetrated also is enabled and being connected by NFC communication between pcb board and vehicle-mounted receiving terminal, extends the function of wireless charger；
Secondly, in the utility model in such a way that pectination copper foil is set on pcb board, PCB plates is enabled to realize filter function,
The cost for adding filter in wireless charger is reduced, while also improving the EMC of charger；
Finally, NFC antenna is added on pcb board in the utility model, enable the function of pcb board more diversified, and enable this
Utility model is connect with vehicle-mounted control terminal, improves the scope of application of the utility model, enables the application bigger of the utility model.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, other drawings may also be obtained based on these drawings.
Fig. 1 is the magnified partial view of the utility model embodiment.
Fig. 2 is the schematic device of the utility model embodiment.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.Obviously, described embodiment is only the utility model section Example, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art institute without creative efforts
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figures 1 and 2, in order to solve on conventional wireless charger, due to using plastic upper cover, caused TX coils
The problem low from excessive, charge efficiency with RX coil-spans, the present embodiment propose a kind of wireless charger, include mainly bottom
Seat 10 and upper cover further includes being set to that wireless charger is outer, RX coils for receiving electric energy on charging terminal and vehicle-mounted
Receiving terminal；After pedestal 10 and upper cover are fixedly connected, closed cube is formed；The transmission end-coil TX coils of charger are set to
In cube, and electromagnetic induction between TX coils and RX coils, it generates electromagnetic coupling and RX coils is set to due to the reaction process
The charging terminal at place starts to charge up；Wherein, upper cover refers specifically to the pcb board 20 with filter function, and the pcb board 20 and vehicle
NFC communication is realized between load receiving terminal.By electromagnetic coupling between TX coils and RX coils in the present embodiment, realize that charging end is not necessarily to
The process of charging is realized in the connection of data line, and reduces the application of plastic upper cover directly as upper cover using pcb board 20, from
And barrier when enabling charging between electromagnetic field is reduced, charge efficiency higher, and charging process is more stable.
More specifically, the pcb board 20 used in the present embodiment is the pcb board 20 with filter function；It is formed on pcb board 20
There is the copper foil 21 of strip, and be uniformly distributed on pcb board 20, forms pectination.The setting of copper foil 21 enables pcb board 20 with filtering work(
Can, remove the EMC for separately setting the cost of filter, while also improving wireless charger itself from, enables the applicable model of the utility model
It encloses wider.
More specifically, the present embodiment is additionally provided with NFC antenna 22 on pcb board 20, PCB plates 20 and vehicle-mounted receiving terminal are enabled
Between NFC connections；Since charging process is by the way of electromagnetic coupling in the present embodiment, NFC communication is had no effect on, and then in PCB
NFC antenna 22 is added on plate 20, is enabled wireless charger that can be realized with vehicle-mounted receiving terminal and is communicated to connect, to increase this implementation
The function of example, enables the application range bigger of the present embodiment.
More specifically, after being distributed copper foil 21 in pectination in the present embodiment, it is set to the center of pcb board 20, and NFC days
Line 22 is set at the outer of pcb board 20, and the function of pcb board 20 in the present embodiment is enabled not interact, and is greatly utilized
The area of pcb board can change the area of wireless charger itself therewith, enable wireless charger more compact and flexible.
In conclusion the present embodiment is on conventional wireless charger, using the pcb board with filter function as upper cover, and
The pcb board is further equipped with NFC antenna, and the EMC of wireless charger itself and charge efficiency is enabled to be improved.
Embodiments described above does not constitute the restriction to the technical solution protection domain.It is any in above-mentioned implementation
Modifications, equivalent substitutions and improvements etc., should be included in the protection model of the technical solution made by within the spirit and principle of mode
