Power-off protection device for computer

Abstract

The invention discloses a power-off protection device for a computer. A shell is arranged on the left side of a displayer, a main board is installed in the middle of the inner cavity of the shell and connected with the displayer through a wire, a current sensor is connected to the upper end of the main board, a charging battery is installed at the upper end of a baffle, a controller is installed at the position, located on the right side of the charging battery, of the upper end of the baffle, the output end of a power interface is connected with the input end of the current sensor, the output end of the current sensor is connected with the input end of the controller and the input end of the main board, the output end of the charging battery is connected with the input end of the main board, and the output end of the main board is connected with the input end of the displayer. The power-off protection device can obtain performance advantages of a desktop computer relative to a notebook computer and also avoid that data is lost and hardware is damaged when power is off, meanwhile, it is not needed to purchase expensive a UPS, cost is low, and usability is good.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a computer power-off protection device. Background technique [0002] At present, computers for personal use mainly include two categories: desktops and notebooks. The power supply mode adopted by desktops is that the mainframe and display are directly connected to the power supply. It will immediately shut down due to power loss, which seriously affects the service life of various components of the desktop, such as CPU, motherboard, hard disk, etc., and more importantly, the files that the user was editing before the power outage will be lost due to failure to save them in time. And it cannot be restored or it is difficult to restore. Although such problems can be avoided by using a notebook, because the notebook also includes a battery as a backup power supply, it will not suddenly shut down due to a power failure, but judging from the current penetration rate, it cannot comp...

Problems solved by technology

[0002] At present, computers for personal use mainly include two categories: desktops and notebooks. The power supply mode adopted by desktops is that the mainframe and display are directly connected to the power supply. It will immediately shut down due to power loss, which seriously affects the service life of various components of the desktop, such as CPU, motherboard, hard disk, etc., and more importantly, the files that the user was editing before the power outage will be lost due to failure to save them in time. And it cannot be restored or it is difficult to restore. Although such problems can be avoided by using a notebook, because the notebook also includes a battery as a backup power supply, it will not suddenly shut down due to a power failure, but judging from the current penetration rate, it cannot completely replace the desktop. Moreover, due to the small size of the notebook, it is difficult to reach the level of some desktop computers in terms of performance. Therefore, it is not realistic at this stage to avoid the above problems by using the notebook. In the prior art, the commonly used power-off protection scheme for computers is generally They all use UPS. UPS is a circuit protection device that contains an energy storage device, uses an inverter as the main component, and stabilizes voltage and frequency output. However, the problem with using UPS is that it has strict requirements on the ambient temperature and needs to be charged and discharged regularly. , there is acid mist phenomenon, therefore, regular maintenance is required for the UPS to prolong its service life and reduce the occurrence of failures, which will undoubtedly increase the maintenance cost of the computer, for this reason, we propose a computer power-off protection device
