Portable wireless charging film with protective circuit

Abstract

The invention discloses a portable wireless charging film with a protective circuit. The portable wireless charging film with the protective circuit comprises a receiving end circuit, a plastic film, a connecting circuit and a charging connector, wherein the receiving end circuit is fixedly arranged above the plastic film; a flat protective shell is arranged outside the receiving end circuit; the receiving end circuit and the charging connector are connected through the connecting circuit; the receiving end circuit comprises an induction coil L3, a bridge rectifier circuit D4, a capacitor C6, a capacitor C5, an LM317 integrated chip, a capacitor C7, a diode D3, a diode D5, a resistor R8, a sliding rheostat R9, a capacitor C8, a resistor R10, a power supply BT1, a triode Q4, a voltage stabilizing diode D7 and a diode D6. By virtue of a simple structure and an integrated circuit, the portable wireless charging film with the protective circuit endows an ordinary equipment battery with a wireless charging function, so that wireless charging of ordinary equipment can also be achieved, and disorder caused when the ordinary equipment is charged is avoided.

Description

technical field [0001] The invention relates to the field of wireless charging film, in particular to a portable wireless charging film with a protection circuit. Background technique [0002] Although the charging technologies of wireless charging mobile phones, wireless charging Bluetooth speakers, or wireless charging tablet computers on the market are relatively complete, they are all independent and specific charging systems for specific devices. Moreover, such devices are often high-end flagship products among similar products, and are expensive. However, few companies have set foot in this field in terms of how to make huge ordinary devices also obtain wireless charging functions and further lower the threshold of wireless charging technology. [0003] Wireless charging technology was originally designed to free people from messy charging cables. However, although the current wireless charging technology frees people from the shackles of charging cables, each device...

AI Technical Summary

Problems solved by technology

However, although the current wireless charging technology frees people from the shackles of charging cables, each device is independent of each other and not universal

When using multiple wireless charging devices, a table full of chargers can also make the home very cluttered

Moreover, at this stage, wireless charging technology is still concentrated on high-end devices of a few brand products, and its high price makes this technology not yet fully popularized.
