A general wireless charging system

Abstract

The invention discloses a universal wireless charge system which comprises a shell, a wire plug and a control circuit, wherein the control circuit comprises an emitting end circuit and a receiving end circuit; the emitting end circuit is arranged on one side of the shell; a switch for controlling the receiving end circuit is further arranged on the shell; the wire plug is electrically connected with the emitting end circuit; the emitting end circuit comprises a transformer T1, a bridge type rectifier circuit D1, a filter capacitor C1, a capacitor C2, a capacitor C3, a capacitor C4, a triode Q1, a triode Q2, a triode Q3, a voltage stabilizing diode D2, a resistor R1, a resistor R2, a resistor R3, a resistor R4, a resistor R5, a resistor R6, a resistor R7, a crystal oscillator Y1, an inductor L1 and an inductive coil L2. The universal wireless charge system is simple in structure, convenient to carry over, capable of charging power for multiple electrical appliances of different direct-current voltages, and has wide market prospects and relatively high social values.

Description

technical field [0001] The invention relates to the field of wireless charging devices, in particular to a universal wireless charging system. 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 is independent of e...

AI Technical Summary

Problems solved by technology

The current wireless charging devices on the market are all one-to-one wireless charging. To realize one-to-many wireless charging, multiple platforms are required for charging.

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.
