1. Field of the Invention
The present invention relates generally to a computer power supplier with a built-in power saving controller to save electric power consumption by the computer mainframe connected to the power supplier. Particularly, the boot button of the computer mainframe can simultaneously activate the electric power supply of the power supplier and the boot function of the computer mainframe, so that, in standby status, the power supply to the computer mainframe and the peripheral equipment connected to it will be completely cut off to save power consumption.

A power supplier (A) (as shown in
However, when the computer mainframe and its peripheral equipment is in standby status, the power supplier (A) is still connected to the AC power, and all electronic components (C) inside still have electric current and still consume electric power, with no energy saving efficacy. Although such a power supplier (A) is configured with a power switch (E), it is configured on the backside of the enclosure of the computer mainframe (A) and is inconvenient to operate. The operator may easily forget to shut it off. Further, the computer peripheral equipment (for example: displayer, multi-media devices, etc.) can be connected to the computer mainframe or be connected to AC power supply through other power sockets. When the computer mainframe is in standby status and the power is not cut off, the peripheral equipment must be shut off by operating the switches of various devices. Such operations are not convenient, and in case the operator forgets to shut off the peripheral equipment by neglect, there will be a waste of energy.
In consideration of the above problems, the inventor of the present invention made detailed research and improvements and disclosed a computer power supplier with a built-in power saving controller.
The primary objective of the present invention is to provide a computer power supplier with a built-in power saving controller, so that the boot button of the computer mainframe can turn on the AC power supply and start the computer at the same time, and the power supplier of the computer mainframe can automatically control the input and output of external AC power supply based on the variation of voltages.
The second objective of the present invention is to provide a computer power supplier with a built-in power saving controller, so that, when the computer mainframe and its peripheral equipment are in standby status, the external AC power supply to various electronic components inside the power supplier can be actually cut off to save consumption of energy.
Another objective of the present invention is to provide a computer power supplier with a built-in power saving controller, so that the external AC power supply to various electronic components inside the power supplier can be cut off when the computer mainframe and its peripheral equipment are in standby status, and their life cycle can be longer.
The present invention has the following technical solutions:
a computer power supplier with a built-in power saving controller, comprising: a power input socket, connected to external AC power supply;
a DC switch circuit, connected to the power input socket to convert the AC power supply into preset voltage DC power supply;
a power control switch, connected to the AC power supply of the power input socket, to turn on or off the AC power supply;
a computer power supply circuit, connected to the power control switch, to convert the AC power supply into DC power supply for the computer mainframe;
a power output socket, connected to the power control switch to introduce the AC power supply from the power input socket for the computer peripheral equipment;
a power start-up circuit, connected to the DC power supply of the DC switch circuit and the power control switch; this power control switch is operated to introduce the AC power supply for the computer power supply circuit;
a power cluster cable, connected to the computer power supply circuit to transmit DC power to the computer mainframe; and
a boot button, with its boot contact connected both to the power start-up circuit and to the computer mainboard, so as to convert AC power into DC power for the computer mainframe and the power start-up circuit.
Based on the attached drawings and the following descriptions, feasible embodiments of the present invention are described in detail.

The DC switch circuit 2 is connected to the power start-up circuit 6, and the power start-up circuit 6 is configured with a start-up boot terminal 61 leading out a boot transmission line 62 to connect the boot contact 71 of the boot button 7, and is also configured with a start-up sensor terminal 63 leading out a sensor transmission line 64 to connect the computer power supply circuit 4, and the boot contact 71 of the boot button 7 is meanwhile connected to the start-up contact of the main board 91 on the computer mainframe 9.
When the present invention is used to start the computer, by pressing the boot button 7, the boot transmission line 62 of the power start-up circuit 6 and the main board 91 of the computer mainframe 9 will simultaneously transmit the start-up signal (refer to
When the computer is shut off, a signal is sent by the computer mainframe 9 through the power cluster cable 8 to shut off the computer power supply circuit 4, and shut off the power of the start-up sensor terminal 63 of the power start-up circuit 6, i.e., the power control switch 3 is turned off to shut off the AC power of the power output socket 5, and only allow the AC power supplier to be connected to the DC switch circuit 2 to supply minimal (about 0.02 W) power for standby power consumption. In the present invention, the boot button 7 is shared by the start-up button or reboot button of the computer mainframe 9.

The power control switch 3 comprises: an LED indicator, a resistor (R4), a diode (D1), a relay (RY), and an AC power output terminal (AC-OUT). When a boot signal is transmitted into the power start-up circuit 6, the relay (RY) will turn on the AC power output terminal (AC-OUT) to output AC power supply for the computer peripheral equipment, and at the same time supply power to the computer power supply circuit 4, which converts the power into multiple types of DC power to start the computer mainframe 9. The LED indicator will show the status of power supply.
The power start-up circuit 6 comprises: a first switch (Q1), a second switch (Q2), resistors (R5, R6, R7, R8), diodes (D2, D3), a DC positive power source (Vcc), a start-up boot terminal 61, a boot transmission line 62, a start-up sensor terminal 63, and a sensor transmission line 64. The boot transmission line 62 leading out from the start-up boot terminal 61 is connected to the boot contact 71 of the boot button 7. Upon starting up, the first switch (Q1) is turned on, DC positive power source (Vcc) is saved into the capacitor (C3), the resistors (R5, R6) are used to extend the discharge time of the capacitor (C3), and extend the start time of the second switch (Q2), and, upon starting up of the second switch (Q2), the power control switch 3 and the computer power supply circuit 4 are activated. Before complete discharge of the capacitor (C3), the sensor transmission line 64 leading out from the start-up sensor terminal 63 and connecting the computer power supply circuit 4 returns multiple DC voltages, and input preset DC voltage power to be supplied to the power control switch 3, so that the relay (RY) will maintain supply of power from the AC power input terminal (AC-IN) to the computer power supply circuit 4 and AC power output terminal (AC-OUT). When turning off the computer, the computer power supply circuit 4 stops to supply power to the start-up sensor terminal 63 of the power start-up circuit 6, even after completion of discharge of the capacitor (C3, C4), the second switch (Q2) will automatically turn off and cut off the power to the relay (RY) of the power control switch 3, and stops the AC power supply to the AC power output terminal (AC-OUT), so as to shut off the power to the computer peripheral equipment. The present invention can also be applied in the power supplier for other electronic equipment for energy saving of the equipment.

The efficacy is enhanced to improve the efficiency of the power supplier, and the power-saving components of the electronic devices are simplified to improve the power-saving effect and working efficiency. By now, there has been no article of identical or similar characteristic published in domestic or overseas publications or publicly used. Therefore the present invention is meeting the prerequisites of the Patent Law.
The mechanical appearance, configurations and overall efficacy disclosed in the present invention for easier description may be altered, replaced or modified, and such alterations, replacements or modifications shall be deemed to be still in the same scope of reflection of the present invention.
