Embodiment one
As shown in Fig. 1~2, the utility model embodiment provides a kind of wireless charger, including wireless charging electroplax 1, fills
2 and first charging wire 3 of electric connection, the both ends of the first charging wire 3 are connect respectively with wireless charging electroplax 1 and 2 electric signal of charging connector,
Wireless charging electroplax 1 includes charging housing 11, antifreeze plate 12 and charge coil 13, and accommodating chamber, antifreeze plate are equipped in charging housing 11
12 are set to the bottom of accommodating chamber, and charge coil 13 is set in accommodating chamber and positioned at the top of antifreeze plate 12, the first charging wire 3
One end connect with 13 electric signal of charge coil, wireless charger further includes charging the mainboard 4, and charging the mainboard 4 is set to charging shell
Outside body 11, charging the mainboard 4 is connect with the other end electric signal of the first charging wire 3, and charging the mainboard 4 also with 2 telecommunications of charging connector
Number connection.Charging the mainboard 4 includes pcb board and the charged electrical element being set on pcb board, since pcb board thickness itself is larger,
And the charged electrical element on pcb board has certain height, and it is relatively thick so as to cause charging the mainboard 4, in the present embodiment
In, charging the mainboard 4 is set to outside charging housing 11 so that charging the mainboard 4 is detached with charge coil 13, then in charging housing 11
It only needs to place charge coil 13 and antifreeze plate 12, in actual design, without the limitation of the thickness size of charging the mainboard 4, if
Meter can be more unfettered, and the thickness of wireless charging electroplax 1 can be as thin as 2 to 3 millimeters, therefore the weight of the charging housing 11 of the present embodiment
Amount is lighter, thinner.
In application aspect, after wireless charging electroplax 1 is detached with charging the mainboard 4, wireless charging electroplax 1 can be fixed easily
In the upper surface of desktop, be such as fixed on bar desk, desk, dining table upper surface, due to thinner thickness, without being filled for fixed wireless
Electroplax and desktop process fixing groove, only need to be attached at desktop；Even if it needs to process fixing groove, the fixing groove of required processing
It is also very shallow fixing groove, processing is simple.The present embodiment will not cause upper surface larger shape to change, charging the mainboard 4
Then be securable to the lower surface of desktop, as bar desk, desk, dining table upper surface, therefore, required fixed environment is simple, no
The normal use of desktop in itself is influenced, there is stronger applicability.
In addition, in wireless charging, charging the mainboard 4 is main heat generating components, and charging the mainboard 4 can release big in charging
The heat of amount.Charging the mainboard 4 is removed out of wireless charging electroplax 1, effectively reduces the heat dissipation of wireless charging electroplax 1 so that wireless
The charging temperature of charging board 1 is lower；Moreover, the heat that wireless charging electroplax 1 generates can be avoided to be transferred to mobile phone, mobile phone is thereby reduced
Charging temperature increases user experience.
After antifreeze plate 12 has the function of that heat conduction, charge coil 13 and charging the mainboard 4 detach simultaneously, antifreeze plate 12 is reduced
Radiate pressure.Meanwhile antifreeze plate 12 has the function of magnetic conduction, gear magnetic, charging the mainboard 4 is detached out of charge coil 13, reduction
The size of antifreeze plate 12, avoids magnetic field from leaking from hub of a spool, thus the antifreeze plate 12 of the present embodiment has preferably gear magnetic
Effect；The antifreeze plate 12 of the present embodiment can be a complete disk, have better magnetic conduction effect.
Further, charge coil 13 is by Circular Winding that at least a conducting wire 131 is coiled into.I.e. charge coil 13 can root
It is entwined according to actual demand by one or more heat conduction.When charge coil 13 is entwined by a charging conductor 131, together
In the case of waiting charge powers, the fever of charge coil 13 is lacked, and performance is stablized.
In order to further reduce the thickness of charge coil 13, the present embodiment, charge coil 13 can be smaller by more diameters
Conducting wire 131 is entwined, and each 131 wound side by side of conducting wire circularizes winding, and the integral thickness of charge coil 13 is conducting wire 131 itself
Diameter so that charge coil 13 is thinner, and wireless charging electroplax 1 can also equally be made thinner；Moreover, multiple conducting wires 131 are side by side
Setting reduces resistance, so as to reduce the calorific value of multiple conducting wires, makes its charging performance more preferable.
Specifically, 131 quantity of the present embodiment conducting wire can be 1,2,3,4,5,6,7,8 or 8
Other quantity more than root.
Further, after charging the mainboard 4 is removed, the canoe of charge coil 13 also changes.As shown in Fig. 2,
Each conducting wire 131 includes initiating terminal 131a and end 131b.Charge coil 13 is twined centered on the initiating terminal 131a of conducting wire 131
Around, and the end 131b of conducting wire 131 is made to be outer edge, it winds in this way, charge coil 13 is wound more compact, is had
Effect ground reduces the size of charge coil 13, finally cause the present embodiment wireless charging electroplax 1 it is smaller.
Further, charging connector 2 is can include transformation mainboard 21, gold with the receptacle terminal of socket grafting, receptacle terminal
Belong to pin 22 and plug casing 23.Transformation mainboard 21 is set in plug casing 23, and metal pin 22 stretches into plug casing 23 simultaneously
It is connect with 21 electric signal of transformation mainboard.Meanwhile be to realize insulation blocking to charging the mainboard 4, charging the mainboard 4 in the present embodiment
It is set in plug casing 23.Transformation mainboard 21 is electrically connected with charging the mainboard 4.In the present embodiment, connected and inserted by receptacle terminal
Seat accesses alternating current, and charging the mainboard 4 is outputed current to after the decompression of transformation mainboard 21, last charged coil 13 emit magnetic field with
It externally charges, in the present embodiment, charging connector 2 is arranged to receptacle terminal, increases the application range of embodiment, any to have socket
Place i.e. can be used.
Further, in the present embodiment, transformation mainboard 21 and charging the mainboard 4 are integrally formed.It is transformation mainboard 21 and to fill
Electric mainboard 4 is same pcb board, and transformation electronic component charged electrical element is set simultaneously on the pcb board, integrated in this way to set
It puts, reduces the use cost of pcb board, also save the inner space of plug casing 23.
Embodiment two
As shown in Figure 3, Figure 4, compared with embodiment one, the difference lies in wireless charger further includes the present embodiment
Second charging wire 5 and the first protective shell 6 for protecting charging the mainboard 4, charging the mainboard 4 are set in the first protective shell 6, and second
One end of charging wire 5 is stretched into the first protective shell 6 and is connect with 4 electric signal of charging the mainboard, and the other end of the second charging wire 5 stretches into
It is connect in plug casing 23 and with 21 electric signal of transformation mainboard.In the present embodiment, the transformation mainboard 21 in receptacle terminal is equally
It is highly exothermic heat source, charging the mainboard 4 is detached with receptacle terminal and connected by 5 electric signal of the second charging wire, can be avoided
Heat source is concentrated, convenient for heat dissipation.When applied to previous desktop, the first protective shell 6 is securable to lower surface or the desktop of desktop
Lower section.
