Data line with charging quantity analog signal display function

Abstract

The invention discloses a data line with a charging quantity analog signal display function. The data line comprises a data line body, the data line body is in a rectangular strip shape, an electric quantity analog signal display screen is arranged on the data line body, and is connected with a charging quantity detection circuit, the charging quantity detection circuit is connected with a data connecting line in the data line body, a charging and discharging loop voltage detection module, a voltage comparison module and a control chip are connected to the charging quantity detection circuit, the voltage values of the power supplies of at least three kinds of common digital products are set in the voltage comparison module, and the output end of the control chip is connected with the electric quantity analog signal display screen. Through the mode, the data line can accurately obtain the charging quantity charged when the data line is connected for charging according to different digital products so that the charged digital products can be unplugged in time, electric power is saved, and the service life of the digital products is prolonged.

Description

technical field [0001] The invention relates to the field of data connection lines, in particular to a data line with the function of displaying an analog signal of charging power. Background technique [0002] When the data cable is connected to the digital product for charging, users often cannot intuitively know whether the charging is complete. They have to go in and turn on the digital product or see if the charging light turns green. Turning on the digital product during charging is a kind of loss to itself. It is sometimes not very effective to look at the charging light to know whether the charging is complete. The design of the charging light is generally equipped with traffic lights, but sometimes when the charging is almost full, the green light will also jump. Full charging also reduces the utilization rate of the battery to a certain extent, so the traditional charging display method can no longer meet the needs of some users.
