Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Please refer to fig. 1 to fig. 6, in this embodiment, the present invention provides a bluetooth-based shared charger, including: bluetooth host system 1, charging control module 5, first voltage conversion module 2, second voltage conversion module 3, pilot lamp module 6, the interface 4 that charges. The first voltage conversion module 2 is electrically connected with the second voltage conversion module 3 and the charging interface 4 respectively, and the first voltage conversion module 2 is used for converting commercial power into 5V direct current and outputting the direct current. The charging control module 5 is electrically connected to the charging interface 4, the charging control module 5 is configured to receive a signal from the bluetooth main control module 1 to control whether the charging interface 2 outputs a voltage, and includes a charging management chip Q3 of 8205 type. Second voltage conversion module 4, charging control module 5, pilot lamp module 6 equally divide do not with bluetooth host system 1 electric connection, second voltage conversion module 4 includes a step-down steady voltage chip U3 for voltage conversion with 5V's voltage conversion for 3.3V's voltage provides bluetooth host system 1, the pilot lamp module includes 7 pilot lamps, is used for instructing the operating condition of filling the money ware. The bluetooth master control module 1 is used for bluetooth communication, data processing and the work of controlling other modules, and includes a bluetooth master control chip U1, the model of bluetooth master control chip U1 is BK3432, bluetooth master control chip U1 includes thirty-two pins, the twenty-first pin of bluetooth master control chip U1 with charging control module 5 electric connection, the twenty-third pin of bluetooth master control chip U1 with second voltage conversion module 3 electric connection, the third pin, fourth pin, thirteenth pin, fourteenth pin, fifteenth pin, twenty-seventh pin, the thirty-third pin of bluetooth master control chip U1 all with pilot lamp module 6 electric connection. In this scheme, the charger still includes button module 7, button module 7 with bluetooth host system 1 electric connection, button module 7 includes four buttons K1, K2, K3, K4.

The utility model discloses a sharing charger has bluetooth function, can realize carrying out bluetooth communication connection with the cell-phone. Referring to fig. 2 to 6, after the charger is connected to the commercial power, the first voltage conversion module 2 converts the commercial power into a 5V dc power and outputs the dc power to the charging interface CON2 and the second voltage conversion module 3, the second voltage conversion module 3 converts the 5V dc power into a 3.3V dc power to be provided to the bluetooth main control chip U1, and the bluetooth main control chip U1 may continuously send out bluetooth broadcast data after being powered on, wait for connection with the bluetooth host, and control the indicator light LED6 to be turned on. When using, can be by the user through the APP scanning setting on the cell-phone on the charger or the near two-dimensional code of charger, long and accomplish the payment after the selection charges, cell-phone APP can send data for the charger through the bluetooth, after bluetooth master control chip U1 received data, to data processing and check, if pass through the check then can pass through twenty first pin output high level, drive the D1 foot output low level of management chip Q3 charges, thereby makes interface D1 that charges can export 5V voltage and charge for equipment such as cell-phones, and pilot lamp LED7 lights simultaneously, and other pilot lamps extinguish.
