Problems solved by technology

[0002] At present, smart electronic devices have become an indispensable tool in people's daily life. Most people use ordinary data cables to charge electronic devices. When it is necessary to check whether the charging is complete, it is often necessary to wake up the electronic device. It is very inconvenient to view on the screen; in addition, when you forget to unplug and cut off the power supply after charging, overcharging may occur, causing damage to the battery of the electronic device, and may cause other serious consequences

Abstract

The present invention discloses a data line with electric quantity display and automatic power-off functions. The data line comprises a device interface, a charging interface and a line body. The device interface is mutually connected with the charging interface through the line body; and the device interface is provided with an electric quantity display module, a voltage detection comparison module and a cut-off switch. Through the electric quantity display module, the schedule of charging can be checked with no need for wakeup of a screen of an electronic device with convenience and intuition; and after the charging is completed, a power-off switch is employed to automatically power off the power source so as to effectively protect a battery of the electronic device and avoid generationof over-charge condition or other accidents.

Description

technical field [0001] The invention relates to the field of electronic equipment accessories, in particular to a data line with power display and automatic power-off functions. Background technique [0002] At present, smart electronic devices have become an indispensable tool in people's daily life. Most people use ordinary data cables to charge electronic devices. When it is necessary to check whether the charging is complete, it is often necessary to wake up the electronic device. It is very inconvenient to view on the screen; in addition, when you forget to unplug and cut off the power supply after charging, overcharging may occur, causing damage to the battery of the electronic device, and may cause other serious consequences. Contents of the invention [0003] In order to solve the above problems, the purpose of the present invention is to provide a data cable with power display and automatic power-off function, which is convenient to check the charging progress of ...
