Abstract
The invention provides an inductive charging device applicable to a portable electronic device. The inductive charging device comprises a movable permanent magnet and an inductive receiver. The movable permanent magnet moves around the portable electronic device and changes the magnetic field of the portable electronic device under moving state. The inductive receiver is arranged in the portable electronic device and comprises a receiving coil, a charging circuit and a charging battery which are combined to form a closed loop. As the magnetic field where the receiving coil exists changes, the receiving coil generates inductive voltage so as to charge the charging battery through the charging circuit. According to the arrangement, through movement of the movable permanent magnet, the magnetic field of the portable electronic device is changed to generate the inductive voltage for charging the charging battery, so that service time of the charging battery is prolonged; during charging, external primary coils and AC (alternating current) power supplies are not required, accordingly leading to use convenience.
Description
[technical field]
The present invention relates to a kind of induction charging device, particularly a kind of induction charging device that also can complete charging without the need to external power.
[background technology]
This means of communication of mobile phone has become the necessity of everyone live and work.In use, every day or be all faced with a unavoidable problem every a couple of days is exactly the charging of mobile phone to mobile phone.Inserted by charger on the power panel on wall, then be inserted on mobile phone by the plug of single line, within second day, pulled up by plug again from mobile phone, plug so year in year out, not only bothers, and often there is broken string, socket gets loose, loose contact.So just occur that the mode of electromagnetic induction is to transmit electric energy, achieves contactless battery charging process, not only facilitates the use of the mobile devices such as mobile phone, the equipment also for being total to unified wireless charging in public occasion is laid a good foundation.Electromagnetic induction refers to the conductor be placed in change magnetic flux, can produce electromotive force.This electromotive force is called induced electromotive force or induced electromotive force, if this conductor is closed into primary Ioops, then this electromotive force can order about electron flow, forms induced current (induced current).
Such as, No. 200980134768.5th, China's Mainland patent application provides a kind of for the charger to induction charging while of one or more battery powdered device.This charger comprises the external unit be suitable for battery powdered device inductive power supply, and this external unit comprises: two or more primary coil pair arranged with circular pattern; AC power supplies, for primary coil to providing alternating current, generate rotating magnetic field between the respective primary coil that primary coil is right; And processor, for driving AC power supplies, within one or more battery powdered device is suitable for being arranged in the circular pattern of external unit, each device comprises secondary coil, and this secondary coil is for surrounding the part in magnetic field and the electric current responsively generated for charging to the battery of device.
But the induction electricity charger that No. 200980134768.5th, China's Mainland patent application and charging method must possess primary coil and provide the AC power supplies of alternating current to primary coil, if do not have primary coil and AC power supplies under environment for use, charging cannot complete.
[summary of the invention]
Main purpose of the present invention is to provide a kind of induction charging device that also can complete charging without the need to external power.
The invention provides a kind of induction charging device, it is applicable to portable electron device; And described induction charging device comprises:
Movable permanent magnet, it moves around portable electron device, and described movable permanent magnet changes the magnetic field of portable electron device under mobile status;
Inducing receiver, it is located in portable electron device, and described inducing receiver comprises receiving coil, charging circuit and rechargeable battery, and receiving coil, charging circuit and rechargeable battery form a closed-loop path; When the magnetic field at receiving coil place changes, receiving coil produces induced voltage, is rechargeable battery charging by charging circuit.
Especially, described movable permanent magnet is finger ring, and finger ring is sheathed on finger.
Especially, described portable electron device is mobile phone or personal digital assistant.
Compared with prior art, the mobile magnetic field changing portable electron device of movable permanent magnet in the present invention, the induced voltage of generation is used for rechargeable battery charging, to extend the service time of rechargeable battery; Charging process does not need outside primary coil and AC power supplies, facilitates use.
[accompanying drawing explanation]
Fig. 1 is the circuit theory diagrams of induction charging device of the present invention.
Fig. 2 is the using state figure of induction charging device of the present invention.
[embodiment]
Refer to shown in Fig. 1 and Fig. 2, the invention provides a kind of induction charging device, it is applicable to portable electron device 10; In the present embodiment, described portable electron device 10 is mobile phone or personal digital assistant.
Described induction charging device comprises:
Movable permanent magnet 20, it moves in portable electron device 10 surrounding, and described movable permanent magnet 10 changes the magnetic field of portable electron device 10 under mobile status; In the present embodiment, described movable permanent magnet 20 is finger ring, and finger ring is sheathed on finger; By the operation of finger touch display screen, movable permanent magnet 20 is moved.
Inducing receiver 30, it is located in portable electron device 10, and described inducing receiver 30 comprises receiving coil 31, charging circuit 32 and rechargeable battery 33, and receiving coil 31, charging circuit 32 form a closed-loop path with rechargeable battery 33; When the magnetic field at receiving coil 31 place changes, receiving coil 31 produces induced voltage, is charged for rechargeable battery 33 by charging circuit 32.
When need by the mode of electromagnetic induction be portable electron device 10 charge time, can movable permanent magnet 20 be sheathed on the finger of user's touching display screen, in the process of finger touch portable electron device 10, movable permanent magnet 20 can be constantly mobile, the mobile magnetic field changing portable electron device 10 of movable permanent magnet 20, the induced voltage that receiving coil 31 produces is used for charging to rechargeable battery 33, thus extends the service time of rechargeable battery 33.When being charged by the mode of electromagnetic induction of the present invention, without the need to operation bidirectional, also without the need to external power, very convenient.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
