Description
Technical Field
The invention relates to a charging device, in particular to a wireless charging device for charging electronic equipment with wireless charging function, such as a mobile phone, a PAD and the like.
Background
The wireless charging technology is derived from a wireless electric energy transmission technology and can be divided into a low-power wireless charging mode and a high-power wireless charging mode, the low-power wireless charging mode is suitable for charging electronic equipment with a wireless charging function, such as a mobile phone, a PAD (PAD application data) and the like, the low-power wireless charging mode usually adopts an electromagnetic induction mode, namely, alternating current with certain frequency of a primary coil generates certain current in a secondary coil through electromagnetic induction, and therefore energy is transferred from a transmission end to a receiving end.
Most of the existing wireless charging devices cannot identify specific model information of electronic equipment such as a mobile phone and a PAD, and usually output the specific model information at rated output power, so that the charging process is uncontrollable, and particularly the charging efficiency is extremely low for the electronic equipment with a quick charging function.
Disclosure of Invention
In view of the problems in the prior art, the present invention provides a wireless charging device, which can improve charging efficiency on the premise of charging electronic devices with wireless charging function, such as mobile phones and PADs.
In order to achieve the purpose, the wireless charging device comprises a mains supply input port and a charging coil which outputs in an electromagnetic induction mode, and is characterized by further comprising a charging control unit and an identification unit, wherein the charging control unit is electrically connected with the charging coil, and the identification unit is electrically connected with the charging control unit; the identification unit comprises an identification module, and charging power data of electronic equipment with a wireless charging function is arranged in the identification module and used for identifying the electronic equipment; the charging control unit comprises an output power adjusting module, and the output power adjusting module is used for adjusting the charging output power.
As a further improvement of the invention, the identification unit further comprises a wireless transmitting module and a wireless receiving module.
Compared with the prior art, the wireless charging device can identify the electronic equipment with the wireless charging function, such as a mobile phone and a PAD (PAD application program) and correspondingly output the charging power, so that the charging efficiency is improved, and the electronic equipment with the quick charging function can be quickly charged.
Drawings
Fig. 1 is a schematic diagram of the present invention.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, the wireless charging device includes a mains supply input port and a charging coil outputting in an electromagnetic induction manner, and is characterized by further including a charging control unit electrically connected with the charging coil and an identification unit electrically connected with the charging control unit; the identification unit comprises an identification module, and charging power data of electronic equipment with a wireless charging function is arranged in the identification module and used for identifying the electronic equipment; the charging control unit comprises an output power adjusting module, and the output power adjusting module is used for adjusting the charging output power.
When the wireless charging device is used, the commercial power input port is electrically connected with commercial power, the electronic equipment with the wireless charging function is placed on the charging coil, the identification unit firstly starts to work, the identification module identifies the electronic equipment according to the charging power data of the built-in electronic equipment with the wireless charging function and feeds the identification result back to the charging control unit, the charging control unit controls the output power adjusting module to correspondingly output the charging power to the charging coil according to the identification result, and the charging coil charges the electronic equipment in an electromagnetic induction mode.
In order to accurately identify the electronic device, as a further improvement of the present invention, the identification unit further includes a wireless transmitting module and a wireless receiving module. In the identification process, the identification unit sends verification information to the electronic equipment through the wireless transmission module, the electronic equipment is operated to feed back an electronic equipment identification code (such as an IMEI code of a mobile phone) to the identification unit of the wireless charging device after verification, and the identification module identifies the electronic equipment according to the electronic equipment identification code and charging power data of the built-in electronic equipment with a wireless charging function and correspondingly outputs an identification result comprising charging power.
This wireless charging device can discern the electronic equipment such as cell-phone, PAD that has wireless function of charging to correspond output charging power, and then improve charge efficiency, to the electronic equipment that possesses the quick charge function, can realize quick charge.
