Abstract

The invention belongs to the technical field of intelligent terminal charging control, and relates to an automatic power-off device and a power-off system with the same. The problems are solved that existing power-off devices are complicated in structure and low in work reliability, and batteries of intelligent terminals are difficult to protect reliably. The device is characterized in that a baseand a rotary reset disk are parallel and are fixedly connected to the two ends of a torsion spring respectively; the interior of the rotary reset disk is conductive, the outer surface of the rotary reset disk is insulated, the rotary reset disk is fixedly provided with two sliding conductive sheets which are not in contact with each other, and a current path is formed between the two sliding conductive sheets; a mains input binding post and a controllable power output binding post which are fixedly arranged on the insulating base are matched with the two sliding conductive sheets respectively; the base, an electromagnet, an elastic piece and a positioning bayonet are sequentially and fixedly connected; the rotary reset disk is provided with a positioning hole matched with the positioningbayonet; the electromagnet, an electromagnet power supply and a controller are sequentially connected; the magnetic force of the electromagnet is greater than that of the elastic piece. The inventionfurther discloses the power-off system with the automatic power-off device.

Description

technical field [0001] The invention belongs to the technical field of intelligent terminal charging control, and in particular relates to an automatic power-off device and a power-off system including the automatic power-off device. Background technique [0002] The widespread use of smart terminals such as mobile phones and tablet computers and the emergence of various life-related apps have led to a significant increase in the utilization rate of smart terminals. Therefore, many users arrange the charging time of smart terminals after going to bed at night, and in general, smart terminals The time of connecting with the mains is as long as 8-10 hours. Although the power management module of a general smart terminal has a charging protection function, the power management module is used for charging protection. After the charging is completed, the smart terminal is not physically isolated from the mains. When the power management module fails, the protection will fail. , ...
