Description
Affiliated technical field
The utility model relates to a kind of lithium battery of radio induction charging, and this lithium battery adopts electromagnetic induction principle, at inside battery wireless induction electric energy receiving system is set, and can receive the energy of electromagnetic field of external emission, generates induced current, gives lithium cell charging.This radio induction charging lithium battery can be used for mobile phone and other electronic equipments, makes things convenient for consumer's wireless charging to use.
Background technology
Present mobile electronic device, major part all have a lithium battery for it energy to be provided, and lithium battery charges to it through charger when electric energy exhausts, recycles then.When increasing product and increasing equipment frequency of utilization take place; Charging has just become a kind of important life content; Manufacturer comes to lithium cell charging in the various charging methods of trial; In order to solve the worry of existing band line charging, the device that the consumer hopes to occur wireless charging makes things convenient for the charging of equipment, shows the individual character of product simultaneously.Manufacturer also is desirable to provide the more distinctive product to the consumer, promotes product competitiveness.
Present wireless charging product, the overwhelming majority all are to be independent of design of electronic devices and production (such as the stand-by power supply of wireless charging), but all fail to carry out the technology combination with the former packed battery of electronic equipment, so use very inconvenience.
Summary of the invention
In order to solve the wireless charging problem of electronic equipment Central Plains packed battery, realize that electronic equipment itself has the function of wireless charging, improve the integrated level of wireless charging product, the utility model provides a kind of lithium battery of radio induction charging.Be on the basis of the original-pack lithium battery of electronic equipment; Increase the wireless electromagnetic induction receiving system; Consider simultaneously spatial content problem and the faradic management and the indication problem of former packed battery again; The Circuit management and the indicating section of wireless electromagnetic induction receiving system are not arranged on inside battery, transfer to the motherboard design of electronic equipment and accomplish, can reduce the design space loss of the lithium cell of inside battery like this; Realize the microminiaturization design principle of battery, be convenient to management and the indication of electronic equipment simultaneously the wireless electromagnetic induction charging.
The utility model is that the technical scheme that its technical problem of realization is taked is: the positive pole of lithium cell, negative pole and lithium cell baffle are electrically connected, through being electrically connected with anodal golden finger, the negative pole golden finger of battery after the protective circuit; Induction electric energy receiving coil and magnetic conduction sheet tightened together constitutes wireless electromagnetic induction electric energy receiving system, the two ends of induction electric energy receiving coil through the independent circuits on the baffle and 2 independently the induction coil golden finger be electrically connected; Separate with antifreeze plate in the middle of induction electric energy receiving system and the lithium cell, lithium cell, lithium cell baffle, antifreeze plate, induction electric energy receiving system are encapsulated in the battery container together.Lithium cell discharge and recharge and the output of the electric current of electromagnetic induction receiving system all realizes that through a plurality of golden fingers on the battery external electric connects.
When applying charging voltage and electric current on the anodal golden finger of battery and the negative pole golden finger, the lithium cell in the battery is realized charging, and when being connected load on anodal golden finger and the negative pole golden finger, the external discharge of the electric core in the battery provides electric energy.When wireless electromagnetic induction electric energy receiving system receives induced current; Induced current is externally exported through 2 induction coil golden fingers; Electric power management circuit and indicating circuit through on the electronic equipment host circuit board carry out rectification and voltage management with induced current, give the lithium cell charging of lithium battery interior; Realize the function of wireless charging, induced current uses through can directly offering equipment after managing simultaneously.
The beneficial effect of the utility model is that the wireless electromagnetic induction receiving system is built in the inside battery in the electronic equipment, can realize wireless electromagnetic induction easily; Produce induced current; Give the electric core charging in the electric device battery, do not change the use habit of consumer electronic equipment.Simultaneously, faradic management and indicating circuit move on to outside the battery of electronic equipment, can bigger design space be provided for lithium cell, make things convenient for the battery design of manufacturer, are convenient to carry out the various work indication designs of radio induction charging simultaneously.
