Summary of the invention
In view of the foregoing, it is necessary to which a kind of convenient electronic device of charging is provided.
A kind of wireless communication device carries out nothing using the induced current generated from the first induction coil of charging unit
Line charge electricity, the electronic device include the second induction coil, controller, charging circuit and battery, and second induction coil is by filling
Circuit is electrically connected to controller and battery, which is used for the inductive electromagnetic generated according to the first induction coil
Field generates induced current；The charging circuit is used to be input to battery after induced current is carried out conversion and transformation, to fill to battery
Electricity；The controller is for detecting the electrical power that the electronic device is received from charging unit, and from electrical power detected
Data in analysis obtain maximum electric power, when electrical power reaches maximum electric power again, issue prompt.
Above-mentioned electronic device by the first induction coil and the second induction coil generation induced current electron device into
Row wireless charging, charging is convenient, while when first induction coil is Chong Die with the hub of a spool of the second induction coil, the controller
Prompt is issued, charge efficiency is improved.
Detailed description of the invention
Fig. 1 is the charging schematic diagram of the electronic device of present pre-ferred embodiments.
Fig. 2 is the functional block diagram of electronic device described in Fig. 1.
Main element symbol description
The present invention that the following detailed description will be further explained with reference to the above drawings.
Specific embodiment
Fig. 1 and Fig. 2 is please referred to, presently preferred embodiments of the present invention provides a kind of electronic device 100, can be mobile phone, individual
Digital assistants (PDA), tablet computer etc..The charging unit 200 that the electronic device 100 matches by one realizes wireless charging.
The charging unit 200 includes the first induction coil 1 and battery charger cradle 201, and alternating current passes through first induction coil 1
When, which generates induction field.The battery charger cradle 201 is used to place the electronic device 100 for needing to charge.It should
201 place plane of battery charger cradle is parallel to 1 place plane of the first induction coil.
The electronic device 100 includes the second induction coil 2, controller 3, charging circuit 4 and battery 5.Second line of induction
Circle 2 is electrically connected to controller 3 and battery 5 by charging circuit 4.
The induction field generation induced current that second induction coil 2 is used to be generated according to the first induction coil 1, this
Two induction coils, 2 place plane is parallel to 1 place plane of the first induction coil.
The charging circuit 4 is used to be input to battery 5 after induced current is carried out conversion and transformation, to charge to battery 5.Tool
Body, the second induction coil 2 receives the induced current of first induction coil 1, which is input to charging circuit 4,
Induced current is converted to direct current by the charging circuit 4, and converts voltages into the charging voltage of suitable battery 5.
The controller 3 is used to detect the charging electrical power that the electronic device 100 is received from charging unit 200, and
Analysis obtains maximum electric power from the data of electrical power detected, described when electrical power reaches maximum electric power again
Electronic device 100 issues prompt (such as screen text prompt, auditory tone cues and vibration prompting), at this time first induction coil 1
It is Chong Die with the hub of a spool of the second induction coil 2, charge efficiency highest.Specifically, the mobile electronics being placed on battery charger cradle 201
Device 100,3 real-time detection of the controller charging circuit 4 pass through charging electricity to the charging current and charging voltage of battery 5
The product of stream and charging voltage obtains the electrical power of battery 5, since charging circuit 4 has certain electrical power during the charging process
Loss, therefore, the electrical power that the second induction coil 2 senses is actually the product of the electrical power Yu an efficiency parameters.Cause
This, controller 3 can calculate the second induction in conjunction with the value of the efficiency parameters by detection charging current and charging voltage
The electrical power that coil 2 receives.The also default time threshold of controller 3, such as 5s, the i.e. controller 3 detect the electronic device
A maximum electric power is taken out in 100 electrical power in 5s；Then electronic apparatus 100 again, when the electrical power detected reaches
When to maximum electric power, which issues prompt, so that it is determined that electronic device 100 is placed on the position of battery charger cradle 201.
The working principle of the electronic device 100 is further illustrated below, the electronic device 100 of required charging is placed on and is filled
The battery charger cradle 201 of electric installation 200, the mobile electronic device 100, the second induction coil 2 receive the sense of first induction coil 1
Answer electric current, which is input to charging circuit 4,3 real-time detection of the controller charging circuit 4 to the electrical power of battery 5,
And a default time threshold, the controller 3 detect that the electronic device 100 takes out a maximum in the electrical power in time threshold
Electrical power；Then electronic apparatus 100 again, when the electrical power detected reaches maximum electric power, the controller 3 sending is mentioned
Show, so that it is determined that electronic device 100 is placed on the position of battery charger cradle 201, first induction coil 1 and the second induction coil at this time
2 hub of a spool overlapping, charge efficiency highest.
Electronic device 100 of the invention generates induced current electron by the first induction coil 1 and the second induction coil 2
Device 100 carries out wireless charging, and charging is convenient, while first induction coil 1 is Chong Die with the hub of a spool of the second induction coil 2
When, which issues prompt, to determine that electronic device 100 is placed on the position of battery charger cradle 201, to improve charge efficiency.
