Abstract
The utility model discloses a desktop computer with an external battery. The desktop computer comprises a computer display screen, a computer host, an alternating current/direct current transformer and a battery. The input terminal of the alternating current/direct current transformer is connected with electric supply. The output terminal of the alternating current/direct current transformer is connected with the battery. The battery is connected with the computer host. The alternating current/direct current transformer and the battery are placed outside the computer host. The alternating current/direct current transformer is provided with a power socket. According to the above-mentioned pattern, the external battery of the desktop computer can supply power to the computer host under the condition of power failure, and therefore the normal operation of the computer host is maintained.
Description
Technical field
The utility model relates to the Technological Problems In Computer Manufacturing field, particularly relates to the improved desktop computer of a kind of power-supply system.
Background technology
The desktop computer of prior art generally is not furnished with battery, civil power accesses desk-top computer main board by computer power, be mainboard and relevant device power supply, the power supply of desktop computer can only use when civil power works like this, the outage but if in case civil power meets accident, desktop computer is with out of service, if computer is being processed capsule information when having a power failure, will cause damage because in time not preserving.And if had urgent thing to need computer to process, then under power down mode, would also feel simply helpless.
The utility model content
For above-mentioned deficiency of the prior art, the utility model purpose is to provide a kind of desktop computer of external power supply, and the external power supply of this desktop computer can to the host computer power supply under power down mode, be kept the normal operation of host computer.
For achieving the above object, the technical scheme that the utility model provides is: a kind of desktop computer of external power supply, comprise computer display screen, host computer, ac/dc transformer and battery, the input end of described ac/dc transformer is electrically connected with the city, output terminal connects described battery, described battery connects host computer, and described ac/dc transformer and battery all place outside the host computer.
Preferably, also be provided with supply socket on the described ac/dc transformer.
Preferably, described battery is the charging/discharging type battery.
Ac/dc transformer described in the utility model connects civil power when civil power works, just to the battery charging, when to be had a power failure, just can utilize the power supply in the battery.
Battery described in the utility model can also be to other electrical appliance power supplies, the supply socket that ac/dc transformer described in the utility model is provided with, can insert the small-sized electric appliances such as desk lamp, mobile phone, with under power-off condition, can also use by the external battery of computer.
The beneficial effects of the utility model are: the utility model external power supply can to the host computer power supply in the situation of civil power outage, be kept the normal operation of host computer.
Description of drawings
Fig. 1 is the structural representation of desktop computer one preferred embodiment of a kind of external battery of the utility model;
Each parts mark is as follows among the figure: 1 one ac/dc transformers, 2 one batteries, 3 one host computers, 4 one computer display screens, 5-supply socket.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, the desktop computer of a kind of external battery of the utility model embodiment, comprise: ac/dc transformer 1, battery 2, host computer 3 and computer display screen 4, wherein ac/dc transformer 1 input end connects civil power, output terminal connects battery 2, battery 2 connects host computer 3, and to host computer 3 power supplies, host computer 3 is connected with computer display screen 4.
Ac/dc transformer 1 has guaranteed the stationarity of supply voltage, the interference that makes battery 2 and host computer 3 not changed by external voltage.Battery 2 is behind the connection external power source to battery 2 chargings for discharging and recharging battery, and when extraneous power supply was stopped power supply, the battery 2 that is full of electricity can be to the connected electrical appliance power supply that needs electricity consumption.
Also be provided with supply socket 5 in the present embodiment on the ac/dc transformer 1, with under the mains failure powering-off state, utilize battery 2 to provide power supply to small-sized electric appliances such as desk lamp, rechargeable cellphone batteries.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
Claims (3)
1. the desktop computer of an external power supply, comprise computer display screen, host computer, ac/dc transformer and battery, it is characterized in that, the input end of described ac/dc transformer is electrically connected with the city, output terminal connects described battery, described battery connects host computer, and described ac/dc transformer and battery all place outside the host computer.
2. the desktop computer of external power supply according to claim 1 is characterized in that, also is provided with supply socket on the described ac/dc transformer.
