Title:
MULTI-FUNCTIONAL CHARGING APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/179295
Kind Code:
A1
Abstract:
A multi-functional charging apparatus and system. A first interface circuit (10) and a second interface circuit (11) are respectively externally connected to a first device (100) and a second device (200), so as to read and feed back first and second parameter information, transmit a power supply signal, and provide a channel for data transmission. A main control circuit (40) correspondingly outputs a control signal to a switch circuit (20) according to the parameter information, so as to turn on the switch circuit correspondingly; the switch circuit (20) transmits a power supply signal to a voltage conversion circuit (30), and controls the first device (100) to charge the second device (200) or controls the second device (200) to charge the first device (100) in a wired manner; and the voltage conversion circuit (30) converts the power supply signal into a working voltage signal and charges a third device (300) in a wireless manner. By externally connecting to the first device (100) and the second device (200) by means of the interface circuits, the multi-functional charging apparatus and system can charge the third device (300) in a wireless manner and charge a power receiver in the first device (100) and the second device (200) in a wired manner, and can realize data transmission, and compensate for the use of a device port during charging, having various functions, high practicability, and good user experience.
