Description

A kind of multi-operation mode Wireless charging coil device

Technical field

This utility model relates to wireless power transmission field, especially relates to a kind of Wireless charging coil that can be suitably used for multi-operation mode.

Background technology

In mobile phone wireless charging system, receiving coil, by the mode of resonance or electromagnetic induction, receives the electromagnetic energy that transmitting terminal sends, and is converted to the voltage or electric current that are available for load use through related circuit.

Existing wireless charging technology is owing to defining different industry standards based on different know-whies (magnetic induction, magnetic resonance etc.) or working condition, and main has Qi standard, PMA standard and A4WP standard. Requirement according to various criterion, the design of its corresponding electric component such as transmitting coil, receiving coil, shielding magnetic sheet, control chip etc. also can be different. These differences cause that the supplier in industry is when various criterion, and above-mentioned electric component re-starts design all possibly.

In order to be able to wider array of adaptability, the supplier of control chip has been carried out the exploitation of multi-operation mode chip the success obtained, it is possible to use a chip carrys out the product of adaptive different radio rechargeable standard. But, for receiving or transmitting coil, in order to meet the multimode operation demand of terminal, it is desired nonetheless to individually making the coil being suitable for various various criterion then to concentrate and put together (as shown in Figure 1), this structure not only increases the complexity of system structure and the cost of coil.

Summary of the invention

For the problems referred to above, this utility model provides a kind of multi-operation mode Wireless charging coil being adapted to various criterion pattern.

This utility model be the technical scheme is that by its technical problem of solution

A kind of multi-operation mode Wireless charging coil device, including control unit, coil body and first, second lead-out wire, it is characterized in that: described first lead-out wire is provided with one, and the second lead-out wire is provided with at least two, described second lead-out wire is connected with control unit by a selection switch.

Wherein, described coil body is formed by a concentric winding of continuous conductors, and described first lead-out wire is arranged on outermost layer or the innermost layer of coil body, and described second lead-out wire is arranged on the different parts of coil body from outside to inside.

As the further improvement of such scheme, described coil body is planar coil.

Wherein, described second lead-out wire has three, respectively corresponding Qi standard, the mode of operation of PMA standard and A4WP standard.

As the further improvement of such scheme, the cross section of described wire is rectangle or approximate rectangular.

The beneficial effects of the utility model are: multi-operation mode Wireless charging coil device of the present utility model, through reasonably design, plural second lead-out wire is set at the different parts of same circle coil, second lead-out wire is connected to control unit further through selection switch, finally it is linked into charging terminal, the second corresponding lead-out wire is selected according to different mode of operations, to meet the demand of different working modes, reduce complexity and the production cost of circuit.

Detailed description of the invention

Below with reference to embodiment and accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is clearly and completely described, to be completely understood by the purpose of this utility model, feature and effect. Obviously; described embodiment is a part of embodiment of the present utility model, rather than whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art obtains under the premise not paying creative work, belong to the scope of this utility model protection.

With reference to Fig. 2 and Fig. 3, a kind of multi-operation mode Wireless charging coil device, including control unit 4, coil body 1 and first, second lead-out wire 2,3, described first lead-out wire 2 is provided with one, second lead-out wire 3 is provided with at least two, and described second lead-out wire 3 is connected with control unit 4 by a selection switch.

Wherein, described coil body 1 is formed by a concentric winding of continuous conductors, and described first lead-out wire 2 is arranged on the outermost layer of coil body 1, and described second lead-out wire 3 is arranged on the different parts of coil body 1 from outside to inside, and is all disposed within the same face of coil body.

Described coil body 1 is planar coil; It is preferably two opposite side parallel and adjacent to the class rectangular configuration that connection limit, both sides is arc.

Wherein, described second lead-out wire 3 has three, and combine respectively corresponding different mode of operation from the first lead-out wire, and these mode of operations include Qi standard, PMA standard and A4WP standard or or different performance requirement.

In order to obtain less coil thickness and better radiating effect when sectional area of wire is identical, the cross section of described wire can adopt rectangle or approximate rectangular.

With further reference to Fig. 4, the second embodiment of the present utility model, the first lead-out wire 2 of this embodiment is arranged on the innermost layer of coil body 1, and the second lead-out wire 3 is arranged on the different parts of coil body 1 from outside to inside, and is arranged on the same face of coil body;
