Abstract
The utility model relates to a wireless charging system comprising a battery; an induction coil used for receiving electromagnetic wave and converting the electromagnetic wave into electric energy; and a control circuit electrically connected with the induction coil for controlling the electric energy converted by the induction coil to wirelessly charge the battery. The structure of the utility model has the charging mode of charging an embedded battery through a charging circuit in a portable product and increases a wireless receiving and charging mode, which not only generates no interference or damage on the original structure, but also increases the charging convenience of users.
Description
Technical field
The utility model relates to a kind of charge power supply of portable terminal, more specifically is, it relates to a kind of portable terminal wireless charging power supply.
Background technology
The 21st century people have got into the information life epoch.Mobile terminal devices such as digital product such as mobile phone, digital camera, palmtop PC become the essential product of people's life.And when the embedded battery of these portable products because of electric weight is not enough can't operate as normal, must charge immediately and could recover operate as normal.Yet traditional embedded battery, its charge mode all adopt the charge circuit of charger or product itself to see through the connection of charging wire connection or connector etc., accomplish the charging to embedded battery.
But existing technology exists following weak point:
One, the charging wire of various brands portable product or connector etc. is incompatible; Cause charger to carry out the compatibility charging to the embedded battery of various brands portable product.
Two, charge immediately for the user who uses portable product for temporary needs, have many very inconvenient;
Three, because charger incompatible; Then need dispose many chargers; Cause the waste of purchase to reach destruction to environmental protection.
In view of this, but the power supply of a kind of wireless charging of research real belong to necessary.
The utility model content
The utility model technical problem to be solved aims to provide a kind of novel wireless charging power supply, to overcome above-mentioned deficiency.
For realizing above-mentioned purpose, the utility model has adopted following technical scheme, that is, a kind of wireless charging system, it includes battery; Induction coil is used for receiving electromagnetic wave, and converts this electromagnetic wave into electric energy; Control circuit is electrically connected with this induction coil, in order to control the electric energy that this induction coil changes this battery is carried out wireless charging.
Described wireless charging system wherein, also includes a battery protecting circuit.This battery protecting circuit and this control circuit are arranged at a side of a printed circuit board (PCB).This battery includes battery and battery case.This induction coil is built in flexible PCB.This induction coil is the copper wire coil, and is fixed on the insulation board.This induction coil is the copper wire coil, and is embedded in the insulation shell.This copper wire coil and this insulation shell one ejection formation.
Described wireless charging system, wherein, opposite side is provided with the contact on this printed circuit board (PCB), and this gets an electric shock in order to wired charging.
Described wireless charging system, wherein, this battery is lithium ion battery or lithium polymer battery.
Adopt the structure of the utility model; Charge circuit carries out the charging modes in possessing embedded battery dependence portable product itself; The pattern that increases wireless receiving charging is again charged, and does so neither to interfere or destroy original framework, increases the convenience of user in charging again.
