Abstract
The invention discloses a mobile phone with wireless charging electromagnetic conversion. The mobile phone is characterized in that at least one overlap is arranged in the mobile phone and at least one positioning device is arranged in a charger for charging the mobile phone, wherein the positioning device is wound by a winding of a primary coil in sequence; the overlap is arranged below a secondary coil. When the mobile phone is required to be charged and is placed on the charger, power is directly transmitted to the primary coil by a control module, the positioning device produces electromagnetism, the overlap moves towards the positioning device to vertically overlap the secondary coil, and the control module changes a power supply into a continuous on-off state, so the primary coil changes into the oscillation work, the oscillation change of the primary coil can be effectively received by the secondary coil, the output efficiency of the secondary coil is improved, and a mains supply is saved, and the charging time is shortened. Reliable overlapping of the primary and secondary coils is realized to guarantee the transmission efficiency of charging.
Description
Technical field
The present invention relates to a kind of mobile phone, is the mobile phone with wireless charging electromagnetic conversion concretely.
Background technology
Mobile phone wireless charger is the superimposed of the one-level coil on charger and the secondary coil in mobile phone, after superimposed, makes a secondary coil become one group of transformer, thus realizes the charging to mobile phone.But in order to ensure the effectively superimposed of a secondary coil, some technology have made two groups of one-level coils to improve the superimposed degree of coil, intensified charging efficiency, and such result causes the rise of cost and the complexity of product.
Summary of the invention
Mobile phone with wireless charging electromagnetic conversion provided by the present invention, has and makes the reliably superimposed of the one-level coil of charger and the secondary coil of mobile phone, to ensure the efficiency of transmission of charging.
The present invention realizes with following technical scheme: this is with the mobile phone of wireless charging electromagnetic conversion, it is characterized in that, described embedded in mobile phone puts minimum one piece of superimposed body, and in the charger charged the phone, minimum a slice positioner is installed, described positioner is wound around in order by the coiling of one-level coil, and superimposed body is arranged on below secondary coil.
Further, when mobile phone needs charging to be placed on charger, control module is delivered directly to one-level coil power supply, positioner produces electromagnetism, after superimposed body moves make a secondary coil vertically superimposed to positioner, and the on off operating mode that control module continues power supply instead, one-level coil is made to become oscillatory work, effective guarantee secondary coil effectively can receive the change in oscillation of one-level coil, improves the delivery efficiency of secondary coil, saves civil power and shortens the charging interval.
Further, secondary coil generation current through live part to charging mobile phone battery, the energy state of radiating portion emission cell is to receiving unit, receiving unit controls the operating frequency of oscillating part according to the saturation of battery, realize controlling the frequency of oscillation of one-level coil, until the saturated rear stopping of battery.
