Description

Technical Field

[0001] This utility model relates to the field of charging data cable technology, and in particular to a charging circuit and charging data cable for a one-to-two charging data cable. Background Technology

[0002] With the widespread adoption of smart devices, users' demand for multi-device collaborative charging and data transfer is growing. Traditional charging cables typically use a single-interface design, providing charging or data transfer capabilities for only a single device. However, in everyday use, users often need to charge two devices simultaneously (such as a phone and tablet, or a phone and headphones) or perform cross-device data interaction while charging. Although some "one-to-two" charging cables have appeared on the market, they still have significant technical shortcomings in practical applications, making it difficult to meet users' charging needs. For example, the charging circuit structure of existing one-to-two charging cables is relatively simple and cannot meet the requirements of intelligent charging. Utility Model Content

[0003] Therefore, it is necessary to address the issue that the existing dual-port charging data cable has a relatively simple charging circuit structure that cannot meet the needs of intelligent charging, and to provide a dual-port charging data cable charging circuit and charging data cable.

[0004] A charging circuit for a dual-port charging data cable includes an input interface, a first output interface, and a second output interface. The input interface is used to connect to a power data terminal, and the first and second output interfaces are both used to connect to a power consumption data terminal. The input interface, the first output interface, and the second output interface are all Type-C interfaces.

[0005] The input interfaces are respectively connected to the main control module, the first power distribution module, and the second power distribution module. The main control module is respectively connected to the first interface control module and the second interface control module. The first power distribution module is respectively connected to the first interface control module and the first output interface. The second power distribution module is respectively connected to the second interface control module and the second output interface. The first interface control module is connected to the first output interface, and the second interface control module is connected to the second output interface.

[0006] When the charging circuit of the aforementioned dual-port charging cable is working, the power data terminal provides an initial voltage signal through the input interface. This initial voltage signal is then provided to the main control module, the first power distribution module, and the second power distribution module via the input interface. The initial voltage signal provides the operating voltage to the main control module, thus maintaining its operation. Furthermore, the main control module can communicate with the power adapter through the input interface, with the power consumption data terminal connected to the first output interface through the first interface control module, and with the power consumption data terminal connected to the second output interface through the second interface control module. This allows it to determine the maximum power supply capacity of the power adapter, the charging requirements of the power consumption data terminal connected to the first output interface, and the power consumption data terminal connected to the second output interface, respectively. According to the charging needs of the terminals; further, the main control module can also generate a first charging parameter adjustment command, and send the first charging parameter adjustment command to the first power distribution module through the first interface control module. The first power distribution module can adjust the initial voltage signal based on the first charging parameter adjustment command, so that the adjusted voltage signal supplies power to the corresponding power data terminal through the first output interface; further, the main control module can also generate a second charging parameter adjustment command, and send the second charging parameter adjustment command to the second power distribution module through the second interface control module. The second power distribution module can adjust the initial voltage signal based on the second charging parameter adjustment command, so that the adjusted voltage signal supplies power to the corresponding power data terminal through the second output interface. It can be seen that the charging circuit of this one-to-two charging data cable can intelligently charge the power data terminals connected to the first output interface and the second output interface according to the maximum power supply capacity of the power adapter, the charging needs of the power data terminals connected to the first output interface and the charging needs of the power data terminals connected to the second output interface, greatly improving the intelligence of charging.

Furthermore, the main control module can communicate with the power adapter through the input interface, with the power consumption data terminal connected to the first output interface through the first interface control module, and with the power consumption data terminal connected to the second output interface through the second interface control module. This allows it to determine the maximum power supply capacity of the power adapter, the charging requirements of the power consumption data terminal connected to the first output interface, and the power consumption data terminal connected to the second output interface, respectively. According to the charging needs of the terminals; further, the main control module can also generate a first charging parameter adjustment command, and send the first charging parameter adjustment command to the first power distribution module through the first interface control module.
