Embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to Fig. 2, the structural representation of a kind of wireless charger one embodiment has been proposed.
Present embodiment wireless charger 1 comprises coil 10 and the charging conversion circuit 20 that is connected with coil 10, and coil 10 is integrated on the battery 2, and coil 10 can receive electromagnetic energy, and is converted into electric energy by charging conversion circuit 20, transfers to battery 2.
Above-mentioned coil 10 is a secondary coil, is integrated on the battery.Therefore, the battery of integrated coil is placed on the charging platform that is integrated with primary coil, then the electromagnetic energy that produces of charging platform can be received by the coil on the battery 10, thereby can be again by charging conversion circuit 20 electromagnetic energy be converted into electric energy, finishes the charging to battery.
With reference to Fig. 3 and Fig. 4, above-mentioned coil 10 can be integrated on the transversal plane of battery or on the side of battery.Because the output current of charger is smaller, be generally the hundreds of milliampere, so the line of coil 10 footpath can be very little, generally use the line of 0.1mm can be, so directly be that the coil 10 of 0.1mm can satisfy the charging demand fully with line by the electric current of 1000mA.And the lithium battery thickness of extensive use at present is 2-3mm, so line directly is integrated on the common lithium battery for the coil of 0.1mm, also can not influence the use volume of this battery.
Above-mentioned charging conversion circuit 20 can comprise rectification circuit, filter circuit and DC-DC change-over circuit.This charging conversion circuit 20 can be arranged in the electronic equipment, also can be set directly in the battery.When charging conversion circuit 20 is arranged in the electronic equipment, can increase the space in addition again this charging conversion circuit 20 is set, utilize charging conversion circuit 20 in the electronic equipment can finish charging process to battery.When charging conversion circuit 20 is arranged in the battery, though need increasing the space of a part, battery accommodates this charging conversion circuit 20, but because charging conversion circuit 20 can be Small Scale Integration, its shared space is also very little, can not influence the use volume of battery, and charging conversion circuit 20 is set directly in the battery, then this battery can be placed on charging platform separately and charges, and no longer need this battery is positioned over charging together in the electronic equipment, so just greatly facilitate user's use.
With reference to Fig. 5, the structural representation of another embodiment of wireless charger has been proposed.
On the basis of the foregoing description, the present embodiment wireless charger also comprises the condition indication circuit 30 that is connected with above-mentioned charging conversion circuit 20.This condition indication circuit 30 can be arranged in the battery, to show the charged state of battery.The display format of this condition indication circuit 30 can show that perhaps the sound of loud speaker class shows for the LED lamp.
The present embodiment wireless charger is by being provided with condition indication circuit 30 in battery, thereby make battery is placed on when charging on the charging platform, can learn the charge condition of battery by condition indication circuit 30, make that the use of wireless charger is convenient.
With reference to Fig. 6, the structural representation of another embodiment of wireless charger has been proposed.
On the basis of the foregoing description; the present embodiment wireless charger also comprises protective circuit 40; this protective circuit 40 is connected with above-mentioned charging conversion circuit 20; be used to gather the output current of charging conversion circuit 20; and relatively this output current and preset current; if output current surpasses the preset current value, then disconnect being connected of coil 10 and charging conversion circuit 20.
The present embodiment wireless charger is by being provided with protective circuit 40 in battery, make can monitor charging current at any time in the process that battery is charged, and prevents that charging current is excessive and damages battery.
The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
