Abstract
A kind of notebook computer with power failure protection module relates to field of computer technology.The present invention includes adapter, battery charging and discharging module and notebook mainboard.Its design feature is that it also comprises the power failure protection module of being made up of the control circuit that is connected in series successively, charging circuit, farad level storage capacitor and discharge circuit.Civil power provides DC voltage to the power supply of the powering mode circuit for detecting in the notebook mainboard and simultaneously to battery charging and discharging module and power failure protection module charging by adapter, and the output of battery charging and discharging module and power failure protection module links to each other with the powering mode circuit for detecting respectively.Compare with prior art, the present invention can change the battery charging and discharging module under the situation of constantly electricity work, can prevent that also sudden power from influencing user's operate as normal simultaneously, for computer system provides high-quality power supply.
Description
Technical field
The present invention relates to field of computer technology, can constantly electric notebook computer of working when particularly changing the battery charging and discharging module.
Background technology
The three core batteries that notebook computer adopts, power-on time only is about 3 hours, it is very inconvenient to go out to handle official business for some business people.Therefore a lot of notebook computer producers begin to produce the double cell notebook computer, and three core batteries and standby six core batteries are provided, and are service time about ten hours, enjoy business people's favor.In the prior art, double cell need just can be changed when shutdown, and starting shooting again behind the battery altering makes troubles to the user again; There are some users to understand the battery that charged mistake is pulled up notebook computer in addition, might damage the data that the user is operating.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the purpose of this invention is to provide a kind of notebook computer with power failure protection module.It can change the battery charging and discharging module under the situation of constantly electricity work, have characteristics easy to use, as not destroy user data.
In order to reach the foregoing invention purpose, technical scheme of the present invention realizes as follows:
A kind of notebook computer with power failure protection module, it comprises adapter, battery charging and discharging module and notebook mainboard.Its design feature is that it also comprises the power failure protection module of being made up of the control circuit that is connected in series successively, charging circuit, farad level storage capacitor and discharge circuit.Civil power provides DC voltage to the power supply of the powering mode circuit for detecting in the notebook mainboard and simultaneously to battery charging and discharging module and power failure protection module charging by adapter, and the output of battery charging and discharging module and power failure protection module links to each other with the powering mode circuit for detecting respectively.
In above-mentioned notebook computer, described charging circuit is composed in series by first diode and first resistance, and discharge circuit is composed in series by second resistance and second diode.
In above-mentioned notebook computer, the withstand voltage of described farad level storage capacitor is 15V.
The present invention is owing to adopted said structure, when notebook computer is worked under the battery charging and discharging module for power supply and capacity prompt when not enough, the user pulls up this battery charging and discharging module, the energy storage farad capacitor is instant just to provide electric energy to the notebook mainboard by discharge loop, until the user installation standby notebook battery charging and discharging module that finishes.Compare with prior art, the present invention can change the battery charging and discharging module under the situation of constantly electricity work, can prevent that also sudden power from influencing user's operate as normal simultaneously, for computer system provides high-quality power supply.
The present invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the electric power-feeding structure synoptic diagram of notebook computer of the present invention;
Fig. 2 is the structural representation of power failure protection module among the present invention.
Embodiment
Referring to Fig. 1 and Fig. 2, the present invention includes adapter, battery charging and discharging module, notebook mainboard and be the farad level storage capacitor 1 of 15V, the power failure protection module that discharge circuit is formed by the control circuit that is connected in series successively, charging circuit, withstand voltage.Civil power provides DC voltage to the power supply of the powering mode circuit for detecting in the notebook mainboard and simultaneously to battery charging and discharging module and power failure protection module charging by adapter, and the output of battery charging and discharging module and power failure protection module links to each other with the powering mode circuit for detecting respectively.Charging circuit is composed in series by first diode 4 and first resistance 2, and discharge circuit is composed in series by second resistance 3 and second diode 5.
During working with notebook computer of the present invention; the powering mode circuit for detecting judges at present to be civil power, battery charging and discharging module or power failure protection module for the notebook main board power supply; and provide Vmain voltage to carry out voltage transitions to the DC-DC translation circuit by powering mode detecting, produce the direct-current working volts that notebook computer needs.When by the civil power normal power supply, it is the notebook main board power supply that civil power provides the 19V DC voltage by adapter, and civil power charges to the farad level storage capacitor 1 in battery charging and discharging module in the notebook computer and the power failure protection module simultaneously.When with the battery charging and discharging module for power supply; run in the time of to pull up the battery charging and discharging module and use the reserve battery charge-discharge modules instead; power failure protection module moment unlatching also begins to the notebook main board power supply; be withstand voltage for the farad level storage capacitor 1 of 15V provides electric energy by discharge circuit to the DC-DC translation circuit, until the user installation reserve battery charge-discharge modules that finishes.
