[0032] It should be noted that, please refer to Figure 7 , the first interface module 100 is a Type-C connector, and the second interface module 130 is a Lightning connector. The Lightning connector includes interfaces VDD33, RX, TX, PW_IN, ID, D-, D+, and TVS diodes D13, D12, D11, D5, and D10 connected to interfaces VDD33, RX, TX, PW_IN, and ID respectively. Interfaces VDD33, RX, TX, and ID are connected to the main control module 110, the interface PW_IN is connected to the power control module 120, and interfaces D- and D+ are connected to the first interface module 100.

Figure 6 As shown, the switch unit 160 can be set to three working modes: charging, charging and data transmission, and data transmission. The display unit 150 can display the remaining power of the second interface module 130, the charging speed change, the charging current or voltage, etc., such as 0-20%, 20%-60%, 60%-80%, 80%-100%, or "full green, red low power or yellow charging", or directly display accurate charging power information such as 58%, which is consistent with the charging power information displayed on the mobile terminal during charging.

[0033] Specifically, see again Figure 4 The interfaces P23, P11, P14, P10, and P12 of the display unit 150 are connected to the 7th pin PA0, the 9th pin PA5, the 17th pin PB4, the 15th pin PA14, and the 16th pin PB3 of the chip U4 respectively.

Diode D2 and diode D3 are connected in parallel to pin 6 of chip U4. The model of chip U1 is XC2430, and the model of chip U4 is 3989AC. The input end of chip U1 is connected to the power line module 170. Pin 11 PB1 of chip U4 is connected to resistors R2 and R1.

The MCU unit 140 can obtain the remaining power of the mobile terminal through the interfaces ID, TX, and RX and control the power control module 120 through the P-IN terminal. The power control module 120 adjusts the output voltage of the second interface module 130 to the first interface module 100 by turning on or off the MOS transistor Q10 and the MOS transistor Q6, thereby charging the mobile terminal.

[0034] Specifically, see again Figure 2When the first interface module 100 is connected to a Type-C charging head, the MCU unit 140 controls the power control module 120 to adjust the voltage based on the remaining power of the mobile terminal connected to the second interface module 130, which can be a step-up fast charge, and the charging power information is displayed on the display unit 150. When the first interface module 100 is connected to a Type-C charging head, the MCU unit 140 controls the power control module 120 based on the remaining power of the mobile terminal connected to the second interface module 130, which can be a step-down flash charge, and the charging power information is displayed on the display unit 150. When the first interface module 100 is connected to a tablet and the second interface module 130 is connected to a mobile phone, the switch unit 160 can be set to transmit data, and the data transmission rate, time, and other information can be displayed on the display unit. Similarly, data can be transmitted while charging. The process here is the same as the above-mentioned single charging process and will not be repeated, thereby improving the application range and operation convenience of the charging display connector.

[0035] It should be understood that by setting the first interface module 100, the main control module 110, the power control module 120 and the second interface module 130, the MCU unit 140 and the display unit 150 are set on the main control module 110, the MCU unit 140 receives the remaining power of the mobile terminal connected to the second interface module 130, and controls the power control module 120 to charge the mobile terminal with the output voltage of the first interface module 100 according to the remaining power, and the MCU unit 140 sends the charging power information of the mobile terminal to the display unit 150. The power control module 120 can control the charging mode of the mobile terminal by adjusting the output voltage of the first interface module 100 to control the charging speed, making the charging operation more flexible and intuitive.
