Abstract
The utility model discloses a wireless charging hand-held device with data exchange function and a charger, comprising a handset terminal and a wireless charging base. The electromagnetic induction principle is adopted, controllable alternating voltage is arranged on an induction coil in the base, then an alternating electromagnetic field is generated in an elementary induction coil of the base. When a receiving induction coil at the handset terminal gets close to the elementary induction coil of the base, the alternating voltage and current are also generated, then provided to a handset power supply management module to charge a lithium cell of the handset after passing through commutating filter and a protective circuit. After the handset is full, a feedback control part in the wireless charging base closes PWM power control, thereby saving energy source.
Description
Technical field
The utility model relates to a kind of charger for mobile phone, especially designs a kind of wireless charging handheld device and charger with data interaction function.
Background technology
The cell-phone charging of prior art all is to adopt cable connector to connect charger, and conventional charger has following shortcoming: the sheet metal that electrically contacts of connector formula charger uses easy loose contact for a long time, causes the charging failure; Be exposed in the environment weak effect of electrostatic defending (ESD) owing to electrically contact sheet metal simultaneously; In some special application scenario, for example military use can't be accomplished waterproofing design.
Summary of the invention
Deficiency at prior art, the purpose of this utility model be to provide a kind of with important information phonebook backup in the mobile phone in the memory of charger inside, the phone directory with backup when needing reverts to a kind of wireless charging cell phone apparatus and the charger with data interaction function that goes in the mobile phone.
The utility model is achieved by the following technical solution:
A kind of wireless charging handheld device and charger of the utility model with data interaction function, comprise the mobile phone end with the wireless charging base.Adopt electromagnetic induction principle; controllable alternating voltage is set on the induction coil in base; then produce the electromagnetic field of alternation on the primary induction coil in base; when the primary induction coil in the close base of the induction receiving coil of mobile phone end; according to electromagnetic induction principle; also produce the alternating voltage and the electric current of same frequency; through offering the cellular phone power supplies administration module to the mobile phone lithium cell charging after rectifying and wave-filtering and the protective circuit; after cell-phone charging is full of; the FEEDBACK CONTROL of wireless charging base inside is partly closed pwm power control, reaches to save energy purpose.
The mobile phone end adopts the flat induction coil that has magnetic shielding cover, the magnetic line of force in the magnetic field that the cutting base primary induction coil produces is at the inner voltage and current that produces of mobile phone end induction coil, the material of magnetic shielding cover can be a Ferrite Material, flat induction coil height is very little, be convenient to be installed in mobile phone inside, in order to prevent the interference of electromagnetic field mobile phone proper communication function of charging, need between mobile phone itself and induction coil, increase magnetic shielding cover; In the mobile phone end, increase simultaneously be not limited to the 2.4GHz wireless communication module finish with the authentication of charging base with communicate by letter, the software section of mobile phone inside increases authentication backup management functional module, finishes the identification and the data backup function of equipment.
Wireless charging base inside is provided with MCU and eeprom memory, authentication and data backup part and induction electricity charger part.Authentication and data backup partly comprise: MCU, 2.4GHz wireless communication module, eeprom memory, power module offers the stable voltage of above-mentioned functions components, the 2.4GHz wireless communication module of base inside receives signal through MCU deciphering, with the information stores that receives in eeprom memory.Induction electricity charger comprises: rectification filtering module, pwm power control module, described power control module and primary induction coil FEEDBACK CONTROL auxiliary induction coil.
Description of drawings
Fig. 1 is the utility model system principle diagram;
Embodiment
As shown in Figure 1, the rectification filtering module that wireless charging base inside includes, the AC220V AC rectification is become direct current about 300V, the pwm power control module produces the whole driving square wave of EDM Generator of Adjustable Duty Ratio according to the FEEDBACK CONTROL of primary coil and the control signal of MCU, the frequency of this square wave at tens KHz between the hundreds of KHz, present embodiment adopts the driving square wave of 120KHz, this drives the square wave drive power control module output square wave about frequency 300V together, at the inner alternating electromagnetic field that produces of primary induction coil, the electric current that flows through in the induced voltage of the FEEDBACK CONTROL auxiliary induction coil of FEEDBACK CONTROL part and the primary induction coil is directly proportional, the FEEDBACK CONTROL auxiliary induction coil makes the efficient of primary induction coil reach maximum according to the far and near duty ratio of suitably adjusting PWM of mobile phone end induction coil; The ADC that this feedback control signal of while is returned MCU provides a sampled signal, after cell-phone charging is full of, the power management module of mobile phone can cut off charge circuit, the electric current that flows through in the primary induction coil will obviously reduce like this, the voltage of FEEDBACK CONTROL auxiliary induction coil induced inside can change along with the size of charging current, the ADC of MCU detects FEEDBACK CONTROL voltage and descends, and MCU just closes pwm power control when dropping to threshold voltage, so that energy savings.
When the induction coil of mobile phone end inside during near charging base, the device authentication administration module of mobile phone inside receives the authentication signal that base sends and starts working, be sent in the base handshake by the 2.4GHz wireless communication module, after base receives handshake, base and carried out device authentication by fill device, when base confirm by fill device be legal by fill device after, MCU sends commands for controlling pwm power control module and starts working, at this moment the induction coil in the base begins to produce electric induction magnetic field, the induction coil of mobile phone end just can induce voltage and current, charges to cellular li-ion battery through the power management module that offers mobile phone behind the rectifying and wave-filtering protection module; The inner MCU control of base pwm power control module quits work if base receives invalid handshake, effectively prevents to fill by mistake, and the while is energy savings also.
In the process of charging, mobile phone authentication backup management module begins to read the important information that is stored on the mobile phone, for example mobile phone is inner and SIM card on telephone directory information, send to base by the block encryption of 2.4GHz radio communication mold, the 2.4GHz wireless communication module of base inside receives behind the useful signal through the MCU deciphering, with the information stores that receives in eeprom memory.Eeprom memory can be preserved information for a long time, even also can preserve data for many decades under the situation that does not have power supply.
Sending the backup information that command request reads EEPROM storage in the base when mobile phone authentication backup management module is, MCU sends to the block encryption of 2.4GHz radio communication mold with data and sends to the mobile phone end, after 2.4GHz wireless communication module in the mobile phone received useful signal, the processing of process mobile phone baseband processor innernal CPU restored in the original phone directory.
