Problems solved by technology

[0003] To overcome the preceding problem, a Y-type cable (or a multi-interface cable) is generally used to connect the standard interfaces of two electronic devices to the external interface of an external device. The above-mentioned method can solve the limitation of the total power limit , but it is inconvenient to use. Users need to prepare an additional Y-shaped connection cable. In some application scenarios, this connection method will generate a large power consumption. If the system overload protection point is reached, the system will shut down directly. cause unexpected loss
[0004] Another solution is to add an additional power jack to the external device, and use the external power supply to supply power to the external device. However, this method still needs to prepare an additional power supply and find another jack when using it. It is still in use. Inconvenience

Embodiment Construction

[0019] Please refer to figure 1 It is a relative interface and composition diagram of the electronic device 10 and the external device 20. The electronic device 10 includes a control unit 110, a touch panel 120, a system power supply unit 130, an interface circuit 140, a man-machine interface 150, a speaker 160 and a detection side unit 170. . The interface circuit 140 has a first interface 141, a second interface 142 and a third interface 143; in the present invention, the electronic device 10 can be a system with more than two interfaces such as a personal computer system, a notebook computer or a tablet computer; the external device 20 There is at least one external interface 211 that can be selectively coupled to the above-mentioned first interface 141, second interface 142 or third interface 143. The coupled interface is used to communicate with the electronic device 10 and the external device 20 through the external interface 211 and to allow the electronic device 10 to ...

Abstract

The invention provides an electronic device with connectors which can be adjusted the providing current. The connectors connect external electronic devices and provide current to power the external electronic devices. User can adjust the current providing status through the user interface of the electronic device according to high or low current requirement of external electronic devices. The electronic device can also read out the power parameter storing in an external electronic device, and adjust the current according to the power parameter.

Description

【Technical field】 [0001] The invention relates to an electronic device with a power supply interface, in particular to an electronic device with a dynamic power supply interface. 【Background technique】 [0002] Electronic devices currently on the market have standard interfaces (such as USB, HDMI, SATA standards, etc.) interfaces, and each type of interface can only supply a fixed voltage and a certain value of current. Taking the USB 2.0 specification as an example, the USB interface can be Supplying 5V / 500mA is equivalent to a total power supply capability of 2.5W. For USB 3.0, 5V / 900mA is equivalent to a total power supply capability of 4.5W. If the connected peripheral device exceeds the limit of the above total power, the electronic device will The over-current protection mechanism will start and stop supplying power to the USB port. [0003] To overcome the preceding problem, a Y-type cable (or a multi-interface cable) is generally used to connect the standard interfa...
