It can be exported by above-mentioned power supply interface into the internal battery of flexible display apparatus and be stored, to realize flexible display apparatus
Charging.After charging, end to end flexible display apparatus can be unfolded, to normally be shown.
In addition, when the flexible substrates 10 with conducting wire 11 are integrated in flexible display apparatus, since conducting wire 11 has in itself
Certain flexibility, therefore the bending performance of flexible display apparatus will not be reduced.And above-mentioned conducting wire 11 has certain stretch-proof
Intensity, so the tensile strength of flexible display apparatus can be improved under the action of conducting wire 11.Further, since flexible substrates
The 10 area conducting wire 11 that is larger, therefore can arranging more for above-mentioned conducting wire 11 of arranging, so as to increase as needed
By the number of turns for the secondary coil 102 that above-mentioned conducting wire 11 is constituted.For example, working as mobile phone so that above-mentioned flexible display apparatus is mobile phone as an example
When having the function of the function of fast charge, i.e. quick charge, secondary coil 102 can be changed by the number of turns of increase secondary coil 102
The voltage of output, such as script can be increased into 9V by 5V by the voltage that secondary coil 102 is supplied to mobile phone.Therefore opposite
In in the prior art, for secondary coil 10 is set to the scheme of interior of mobile phone, the number of turns of the secondary coil 102 in the application
Adjustment space it is bigger, it is more flexible.
On this basis, after flexible substrates 10 are end to end, in order to enable the flexible substrates 10 are able to maintain in cylinder
The bending state of body, and can be improved the precision that two neighboring conducting wire 11 contacts contraposition from beginning to end, guarantee the conducting of secondary coil 102
Performance.Preferably, determine as shown in figure 5, being respectively arranged with the first locating piece 30 and second in the stem of flexible substrates 10 and tail portion
Position part 31.In the case, as shown in figure 3, above-mentioned first locating piece 30 and the second locating piece 31 are for being mutually clamped, so that soft
Property substrate 10 is end to end.Specifically, above-mentioned first locating piece 30 can be the protrusion with card slot, and the second locating piece 31 can
Think the positioning column that can be caught in above-mentioned card slot.
In addition, the present invention also provides one kind for carrying out to any one non-contact power receiving system 01 as described above
The non-contact electric power sending device 02 of charging.As shown in fig. 6, the non-contact power receiving system 01 is set to non-contact electric power hair
It send on the loading end A of device 02.
Specifically, as shown in fig. 7, the non-contact electric power sending device 02 includes recharging base 40.Wherein, recharging base 40
It is inside provided with primary coil 101, the axial direction of the primary coil is perpendicular to loading end A, and one end of the primary coil 101 connects
Connect the power interface 43 on recharging base 40.The power interface 43 is used to provide alternating current to secondary coil 101.The primary coil
101 other end ground connection or connection negative pressure end.
In addition, non-contact electric power sending device 02 further includes the field orientation axis 41 perpendicular to loading end A.The field orientation
Axis 41 is located to be enclosed in the through-hole set by flexible substrates 10 are end to end, and the field orientation axis 41 is for generating primary coil 101
Magnetic field be directed in the secondary coil 102 in flexible substrates 10, thus reduce primary coil 101 generation magnetic field diverging journey
Degree, improves the efficiency of electromagnetic induction.
Wherein, the material for constituting the field orientation axis 41 can be permeability magnetic material, such as metallic iron, metallic nickel and gold
Belong at least one of cobalt.
In conclusion being determined since above-mentioned non-contact electric power sending device 02 is provided with winding by the magnetic field of primary coil 101
To axis 41.Therefore the flexible substrates 10 in above-mentioned non-contact power receiving system 01 can be bent, so that inclination arrangement
In being electrically connected from beginning to end per adjacent two conducting wires 11 in the flexible substrates 10, to form winding and time in the flexible substrates 10
Grade coil 102.In the case, above-mentioned secondary coil 102 is inserted on the field orientation axis 41, and is sent out by non-contact electric power
The loading end A of device 02 is sent to be supported non-contact power receiving system 01.So, can be made by field orientation axis
The primary coil 101 that must be wound on field orientation axis 41 is always positioned in secondary coil 102, so as to improve primary coil
101 with the aligning accuracy of secondary coil 102.During electromagnetic induction, available biggish flux cross section product S and compared with
The instantaneous value u of big induced electromotive force, and then the induced current for flowing through secondary coil 102 can be increased, so that secondary coil 102
Charge efficiency promoted.In addition, non-contact power receiving system 01 provided by the present application charging when, as long as by end to end

01 surrounding.Preferably, since the heat that charging generates generally concentrates the flexible substrates 10 with non-contact power receiving system 01
Between field orientation axis 41.Therefore above-mentioned radiator 42 can be with the end to end position for enclosing the through-hole set of flexible substrates 10
It is corresponding.
Wherein, above-mentioned radiator can be air-conditioning or fan, and by taking fan as an example, the air-out direction of the fan can hang down
Directly and departing from loading end A, add up so as to avoid heat from generating in loading end A, and causes the electricity being located on loading end A
The excessively high phenomenon of sub- device local temperature occurs.
It can be seen from the above, non-contact power receiving system 01 may be constructed with non-contact electric power sending device 02 with Charging
System.Based on this, in order to improve charge efficiency, when above-mentioned non-contact power receiving system 01 includes being integrated with the soft of flexible substrates 10
When property display device, take the mobile phone as an example.It can be placed on the field orientation axis 41 of above-mentioned non-contact electric power sending device 02 multiple
Mobile phone charges simultaneously to multiple mobile phones with realizing.
Specifically, the length of field orientation axis 41 can be lengthened when the model of multiple mobile phones is identical, at this point, multiple hands
Machine is stacked gradually and is inserted on above-mentioned field orientation axis 41.
Alternatively, being bent to form different mobile phones with the hollow of different inner diameters when the model of multiple mobile phones is not identical
Cylindrical body.The lesser mobile phone of size and above-mentioned magnetic field can be successively accommodated in the through-hole formed after larger-size mobile phone bending
Orientation axes 41.And in the prior art, as shown in Figure 1 b in order to charge to multiple mobile phones, needed on the pedestal for the transmitting terminal that charges
With multiple charge positions such as charge position I and charge position II.So need to widen the pedestal of charging transmitting terminal
Size, and the size of 01 recharging base 40 of non-contact power receiving system provided by the invention is not necessarily to widen, to be conducive to save
Save space.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
