Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 2, the utility model provides a kind of computer power 20, has external power source input end 27, comprising:
One computer power body 21 is provided with charging circuit 30 in the computer power body 21;
At least one USB interface 22, USB interface 22 is arranged on the computer power body 21, and electrically connects with charging circuit 30.
In the utility model, in computer power 20, add charging circuit 30, USB interface 22 is installed on the computer power body 21, and USB interface 22 electrically connects with charging circuit 30.Therefore, can be by USB interface 22 outwards power supply constantly, open with computer or closed condition irrelevant.Reach stable power-supplying, economize the electrical equivalent fruit.And in an embodiment of the present utility model, computer power 20 external external power sources 10 are 5VSB under holding state, and promptly under computer power 20 and holding state that external power source 10 is connected, computer power 20 systems keep the wait voltage of 5V.
In the utility model, under computer power 20 closing state, can often provide supply unit by the USB interface 22 of standby power 5V/2A by being installed in computer power 20 of computer power 20 to the outside.This computer power 20 is different from existing pattern by the power supply of the USB on the computer main board 12, is directly by computer power 20 power supplies.Therefore, can provide stable constant again power supply.
Referring to Fig. 3, shown in figure be the back side of computer power body 21, wherein USB interface is arranged at the back side of computer power body 21.In addition, the back side of computer power body 21 is provided with ventilating opening 28.Can make computer power 20 inside have thermal diffusivity preferably by this ventilating opening 28.In addition, external power source input end 27 is arranged at the back side of computer power body 21, is used for being connected of computer power 20 and external power source 10.And the back side of computer power body 21 is provided with 110V/220V voltage transitions interface 26.Can realize conversion between 110V and the 220V voltage by this interface, the electrical equipment that is beneficial to the different electrical power standard uses.
Preferably, in an embodiment of the present utility model, computer power 20 comprises a plurality of USB interface, for example, and first USB interface 23, second USB interface 24, the 3rd USB interface 25.The power specification of above-mentioned a plurality of USB interface is 5V/0.5A; And/or, 5V/1A; And/or, 5V/2A.Referring to Fig. 4, computer power 20 is connected with external power source 10, under holding state, computer main board 12 is under the outage closed condition, and the USB external unit that is connected on first USB interface 23, second USB interface 24, the 3rd USB interface 25 is powered by computer power 20, and the working power specification that can provide respectively is 5V/0.5A, 5V/1A, 5V/2A is to adapt to the use of different USB external units.Particularly the power specification of USB interface is the USB interface of 5V/1A and 5V/2A, and it has satisfied the high power work needs of now increasing USB external unit.Satisfy the charging requirement of corresponding product, also can be as MP3, MP4, the charger of products such as ipod uses, not only power saving but also satisfied multiduty purpose.
The utility model has increased substantially the output power of 5VSB, has saved the power supply adaptor of a lot of external units, as long as computer power 20 is connected, the USB interface that then is arranged on the computer power body 21 can be used normally.And the voltage of its output is stable, increases substantially output power, can provide power supply for one or more USB external unit simultaneously.Particularly now computer peripheral device all has USB interface mostly, can with numerous computer external unit compatibilities, its range of application is wide.Yet because the USB interface on the computer main board 12 still keeps, so preferred, the USB interface that the utility model increases newly is not have data-transformation facility.
In sum, the utility model is by increasing charging circuit in the computer power body, and on the computer power body, USB interface is set, realized that under the situation that computer is closed the USB external unit still can be by being arranged at the USB interface charging on the computer power body.The utility model has improved the output power of computer power under the 5VSB situation, makes the wider of the USB external unit that is suitable for the computer power charging, has made things convenient for the user to be various USB external units chargings.In addition, also the use to computer provides effective protection, has prolonged the serviceable life of computer and other USB external units.
