Description
Technical field
The invention belongs to a kind of adjustable Wireless charging coils of inductance value.
Background technology
With the fast development of wireless charging technology, more and more electronic equipments particularly mobile phone adds wireless charging
Function.
Wireless charging industry currently on the market has more standards, such as Qi standards and Air Fuel standards etc., also has it
The privately owned standard of his some manufacturers.Different standards is also different to the specification of the hardware of wireless charging, thus to transmitting or
The hardware parameter regulation of receiving coil is also different.And the inductance of existing coil is all fixed in the market, is assembled into finished product
It can not just change afterwards.When if necessary to compatible many kinds of specification, it is necessary to which the coil of multiple and different inductance is installed.
Existing product is when being equipped with coil, it can be seen that very multiple and different coils is embedded on product, i.e., it is different
Function be equipped with different coil, this largely all occupies the space of equipment, more next to space with electronic equipment
High trend is more required to mismatch very much.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of Wireless charging coil of adjustable electric sensibility reciprocal, makes a coil
A variety of rechargeable standards can be met, save product space, reduce cost of manufacture.
It is as follows that the present invention solves the technical solution that above-mentioned technical problem is taken：
A kind of adjustable Wireless charging coil of inductance value, including：Multi-turn charge coil, in the head end of coil, end and inside
A lead is drawn in position respectively at least one, so that having different inductance values between different leads.
Preferably, every lead of the Wireless charging coil is connected by moss with circuit, and microcontroller passes through control
The mode of moss processed comes the connecting pin of every lead of control coil and connecting or disconnecting for circuit, so that by controlling not
This pipe enables and the connection of disable different leads and circuit, realizes the adjusting of coil inductance.
The present invention draws lead for coil in different winding positions, can have different parameters between different leads
Value when product needs the coil of a certain parameter, is selected corresponding lead that can achieve the goal, is saved largely for electronic product
Space.
Other features and advantages of the present invention will be illustrated in the following description, also, partly becomes from specification
It obtains it is clear that being understood by implementing the present invention.The purpose of the present invention and other advantages can be by the explanations write
Specifically noted structure is realized and obtained in book, claims and attached drawing.
Description of the drawings
The present invention is described in detail below in conjunction with the accompanying drawings, so that the above-mentioned advantage of the present invention is definitely.Its
In,
Fig. 1 is the appearance diagram of the adjustable Wireless charging coil of inductance value of the present invention；
Fig. 2 is the electrical connection diagram of the adjustable Wireless charging coil of inductance value of the present invention.
Specific embodiment
Carry out the embodiment that the present invention will be described in detail below with reference to accompanying drawings and embodiments, how the present invention is applied whereby
Technological means solves technical problem, and the realization process for reaching technique effect can fully understand and implement according to this.It needs to illustrate
As long as not forming conflict, each embodiment in the present invention and each feature in each embodiment can be combined with each other,
The technical solution formed is within protection scope of the present invention.
The present invention is that one kind is based on the adjustable coil of inductance, and more leads are drawn in coil inside different position, different
There is different inductance values between lead, using moss being controlled to enable and the connection of disable different leads and circuit, you can real
The adjusting of existing coil inductance.
The coil inductance of the present invention is adjustable, can meet a variety of different wireless charging marks using a coil
Standard allows product to be adapted in the market using the wireless charging reception of various criterion or transmitter.
As shown in Figure 1, A and B1 is the head end of coil and end conducting wire, B2, B3, B4 are in the specific position of coil inside
The conducting wire of extraction.Wherein fixed by coil of A using end, it is another to be switched using end between B1, B2, B3, B4.For same
For coil, two more using the wire circle included between end, then inductance value is bigger.So can be as needed,
The conducting wire of multiple needs is drawn in different positions between head end and end, and satisfactory inductance value is obtained with this.
As shown in Fig. 2, it is the electrical connection schematic diagram that the present invention uses in circuit.The conducting wire of each lead end of coil leads to
Moss is crossed with circuit to be connected, and microcontroller can be by way of controlling moss come each lead end of control coil and circuit
Be connected and disconnected from.It is a full bridge driving circuit shown in Fig. 2.When needing using A ends and B1 ends, microcontroller control moss
B2, B3, B4 and circuit disconnect, and B1 is connected with circuit；When A is terminated into positive pole, the circuit that B1 is connected and electricity
Source anode disconnects and accesses power cathode；When A is terminated into power cathode, the circuit that B1 is connected and power cathode are disconnected simultaneously
Positive pole is accessed, that is, forms a full bridge driving circuit.
The present invention draws lead for coil in different winding positions, can have different parameters between different leads
Value when product needs the coil of a certain parameter, is selected corresponding lead that can achieve the goal, is saved largely for electronic product
Space and Material Cost.
Finally it should be noted that：The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention,
Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art, still may be used
To modify to the technical solution recorded in foregoing embodiments or carry out equivalent substitution to which part technical characteristic.
Within the spirit and principles of the invention, any modifications, equivalent replacements and improvements are made should be included in the present invention's
Within protection domain.
