Embodiment

[0029] see figure 1 , figure 1 It is a structural diagram of a fast charging device for a mobile terminal provided by an embodiment of the present invention.

[0030] Such as figure 1 As shown, the mobile terminal fast charging device provided by the embodiment of the present invention includes:

[0031] QC (QuickCharge, fast charging technology) 2.0 / 3.0 charger 1;

[0032] It should be noted that the QC2.0 / 3.0 charger means: QC2.0 charger or QC3.0 charger.

[0033] Specifically, the QC2.0 / 3.0 charger includes a female terminal 11 of a USB Type A interface;

[0034] Specifically, a QC2.0 charger refers to a charger that supports the QC2.0 fast charging protocol. The QC2.0 fast charging protocol supports 5V / 2A (output voltage is 5 volts, output current is 2 amps), 9V / 2A, 12V / 1.5A output power, that is, the highest output power can reach 18 watts; QC3.0 charger refers to a charger that supports QC3.0 fast charging protocol, and its output power is greater than that of QC2....

Abstract

The invention discloses a rapid charging device and system for a mobile terminal. The system comprises a QC2.0 / 3.0 charger. The QC2.0 / 3.0 charger comprises a female end of a USB Type A interface and a USB data line for connecting the QC2.0 / 3.0 charger with the mobile terminal. The mobile terminal comprises a female end of a USB Type C interface. One end of the USB data line comprises a male end of the USB Type A interface matched with the female end of the USB Type C interface. The other end of the USB data line comprises a male end of the USB Type C interface matched with the female end of the USB Type C interface. According to the technical scheme, the charging speed of the mobile terminal with the Type C interface can be remarkably increased, so that the rapid charging device is suitable for the trends of high energy consumption and fast electricity consumption speed caused by high configuration of the mobile terminal and better in user experience.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a fast charging device and system for a mobile terminal. Background technique [0002] The mobile terminal includes devices such as smart phones and tablet computers. These devices generally include a USB (Universal Serial Bus, Universal Serial Bus) interface, and are charged through a charger and a USB data cable, and the charger includes a USB interface. At present, there are two commonly used USB interfaces, TypeA interface and TypeB interface, and TypeC interface has also appeared recently. At present, computers generally adopt Type A interface, mobile phones and other portable electronic devices generally adopt Type B interface, while Type C interface supports positive and negative insertion and USB3. [0003] At present, the charging equipment corresponding to the mobile terminal with the TypeC interface generally uses a charging protocol with a small charging power su...
