Abstract
Description
Technical Field
[0001] The utility model relates to an intelligent power supply, in particular to an intelligent power supply with power outputs of ATX12V and ATX12VO. Background Art
[0002] The power supply is a main device in a computer. With the progress of technology, the specifications of power supplies include various types. For example, ATX12V, ATX 3.0, and ATX12VO. Among them, ATX12V and ATX12VO are the power supply specifications for the motherboard. The old motherboard uses ATX12V for power supply, and the new motherboard uses ATX12VO for power supply. When there are motherboards with two power supply specifications in the market, the problem of supplying power to motherboards with different specifications must be solved.
[0003] Generally speaking, buying a power supply with the same specification as the motherboard is the simplest solution. At present, there is also a solution using a voltage conversion circuit in the market, which converts the power of ATX12VO to the power of ATX12VO (such as TW-M610397). Even manufacturers directly launch power supplies with both ATX12V and ATX12VO power supplies.
[0004] Refer to Figure 1 , for the current pin arrangement 21 of ATX12V. The outputs from left to right in the upper row are +3.3V, -12V, GND, PS_ON#, GND, GND, GND, N / A, +5V, +5V, +5V, and GND. The outputs from left to right in the lower row are +3.3V, +3.3V, GND, +5V, GND, +5V, GND, PWR_OK, +5VSB, +12V, +12V, and +3.3V. Since the pin arrangement 21 of ATX12V is a known technology, it will not be elaborated here. Among them, the pin arrangement 21 of ATX12V has 24 output interfaces.
[0005] Refer to Figure 2 , for the current pin arrangement 22 of ATX12VO. The outputs from left to right in the upper row are PWR_OK, +12VSB, +12V, +12V, and +12V with Sense. The outputs from left to right in the lower row are PS_ON#, GND, GND, GND, and I_PSU%. Since the pin arrangement 22 of ATX12VO is a known technology, it will not be elaborated here. Among them, the pin arrangement 22 of ATX12VO has 10 output interfaces.
[0006] Since there are very significant differences between ATX12V and ATX12VO in terms of circuit design, interface design, cable design, standby voltage and other specifications, integrating ATX12V and ATX12VO into the same power supply will face the following problems:
[0007] I. Complex circuit design:
[0008] ATX12V and ATX12VO use two completely different circuit designs respectively, and their standby voltages are different. The standby voltage of ATX12V is +5VDC, and the standby voltage of ATX12VO is +12VDC. If two different voltage conversion circuits are integrated on the same circuit board, the circuit will be too complex and cause the problem of large volume of the power supply.
[0009] II. Excessive number of output interfaces:
[0010] The pin arrangement 21 of ATX12V has 24 output interfaces, and the pin arrangement 22 of ATX12VO has 10 output interfaces. If the power supply supports the power output of both ATX12V and ATX12VO at the same time, its housing needs to be provided with 34 output interfaces to provide connections for different specifications of computer devices respectively, resulting in the problem of a large number of output interfaces occupying the housing area.
[0011] III. Increased energy consumption:
[0012] For a general power supply that supports the power output of ATX12V and ATX12VO, when the ATX12VO output interface is connected to a computer device for power supply, ATX12V will not be used. However, the general power supply still supplies power to the circuit of ATX12V, and the electronic components in the circuit will generate internal consumption, resulting in the problem of energy consumption. Summary of the Utility Model
[0013] In view of this, the purpose of the present utility model is to provide an intelligent power supply that can reduce the number of output interfaces on the housing and has a simple internal circuit.
[0014] The intelligent power supply includes a power supply unit and an output unit. The power supply unit includes a first power module and a second power module connected to the first power module.
[0015] The output unit includes a common connection output module connected to the first power module, a first output module connected to the first power module, and a second output module connected to the second power module. The first output module cooperates with the common connection output module to output a first power specification, and the second output module cooperates with the common connection output module to output a second power specification.
[0016] Another technical means of the present utility model lies in that the first power supply specification is ATX12V and the second power supply specification is ATX12VO.
[0017] Another technical means of the present utility model lies in that a buck circuit is provided in the first power supply module.
[0018] Another technical means of the present utility model lies in that the common connection output module has a plurality of common connection output ports, and the outputs of the plurality of common connection output ports are respectively a power good signal (PWR_OK), two positive twelve-volt power supplies (+12V), and a ground (GND).
[0019] Another technical means of the present utility model lies in that the power supply unit further includes a switch module disposed between the first power supply module and the second power supply module. When the switch module is in a conducting state, the first power supply module supplies power to the second power supply module. When the switch module is in a cutoff state, the first power supply module cannot supply power to the second power supply module.
[0020] Another technical means of the present utility model lies in that the power supply unit further includes a detection module connected to the switch module. The detection module is used to detect whether the second output module is in use. When the second output module is in use, the switch module is controlled to be in a cutoff state. When the second output module is not in use, the switch module is controlled to be in a conducting state.
[0021] Another technical means of the present utility model lies in that when the detection module detects that one or all of the plurality of second output ports of the second output module are not in use, the switch module is controlled to be in a conducting state.
[0022] Another technical means of the present utility model lies in that the intelligent power supply further includes a transmission unit. The transmission unit includes a first transmission line group. One end of the first transmission line group is detachably connected to the first output module and the common connection output module. The other end of the first transmission line group is provided with a first plug structure, and the first plug structure outputs the first power supply specification.
[0023] Another technical means of the present utility model lies in that the intelligent power supply further includes a transmission unit. The transmission unit includes a second transmission line group. One end of the second transmission line group is detachably connected to the second output module and the common connection output module. The other end of the second transmission line group is provided with a second plug structure, and the second plug structure outputs the second power supply specification.
[0024] Another technical means of the present utility model lies in that the intelligent power supply further includes a transmission unit, the transmission unit includes a third transmission line group, one end of the third transmission line group is detachably connected to the first output module, the second output module and the common connection output module, the other end of the third transmission line group is provided with a third plug structure and a fourth plug structure, the third plug structure outputs the first power supply specification, and the fourth plug structure outputs the second power supply specification.
[0025] The beneficial effect of the present utility model is that the common connection output module can not only form the first power supply specification with the first output module, but also form the second power supply specification with the second output module, which can reduce the number of output interfaces on the outside of the intelligent power supply. When the detection module detects that the second output module is in use, it controls the switch module to be in the cut-off state to prevent electricity from entering the second power module, which has the effect of saving energy and power.

[0052] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments given are not intended to limit the present utility model.
[0053] Please refer to Figure 3 、 Figure 4 and Figure 5 , which is a first preferred embodiment of an intelligent power supply of the present utility model. The intelligent power supply includes a power supply unit 31, an output unit 32, and a transmission unit 33.
[0054] The power supply unit 31 includes a first power supply module 311, a second power supply module 312 connected to the first power supply module 311, a switch module 313 disposed between the first power supply module 311 and the second power supply module 312, and a detection module 314 connected to the switch module 313.
[0055] The output unit 32 includes a common connection output module 321 connected to the first power supply module 311, a first output module 322 connected to the first power supply module 311, and a second output module 323 connected to the second power supply module 312.
[0056] The transmission unit 33 includes a first transmission line group 331 detachably connected to the first output module 322 and the common connection output module 321, a first plug structure 332 disposed at one end of the first transmission line group 331, a second transmission line group 333 detachably connected to the second output module 323 and the common connection output module 321, and a second plug structure 334 disposed at one end of the second transmission line group 333.
[0057] The first output module 322 and the common connection output module 321 cooperate to output a first power supply specification. The second output module 323 and the common connection output module 321 cooperate to output a second power supply specification. In the first preferred embodiment, the first power supply specification is ATX12V, and the second power supply specification is ATX12VO. In actual implementation, other power supply specifications may also be used for the first power supply specification and the second power supply specification, and should not be limited thereto.
[0058] The first power module 311 provides the first output module 322 and the common connection output module 321 with the first power supply specification of ATX12V. The standby voltage of the first power module 311 is +5VDC. The second power module 312 provides the second output module 323 and the common connection output module 321 with the second power supply specification of ATX12VO. The standby voltage of the second power module 312 is +12VDC. In order for the first power module 311 to use the power of the second power module 312, a buck circuit is provided in the first power module 311 to first transform +12VDC into +5VDC, and then the first power module 311 transforms the standby voltage of +5VDC into the first power supply specification of ATX12V. The second power module 312 transforms the standby voltage of +12VDC into the second power supply specification of ATX12VO. Among them, no boost circuit is provided in the first power module 311, and the +12V voltage is given to the second power module 312, which can make the circuit of the first power module 311 simpler, reduce the use of electronic components, and reduce the occupied volume.
[0059] The common connection output module 321 has a plurality of common connection output ports. The outputs of the plurality of common connection output ports are respectively a power good signal (PWR_OK), two +12V power supplies, and a ground (GND). Please refer to Table 1 below. In the first preferred embodiment, the common connection output module 321 has 10 common connection output ports. The outputs of the upper row of common connection output ports from left to right are PWR_OK, +5VSB, +12V, +12V, and +3.3V. The outputs of the lower row of common connection output ports from left to right are +3.3V Sense, +5VSB, +5V, +5V, and GND. In actual implementation, the common connection output module 321 can be provided with only PWR_OK, +12V, +12V, and GND, or other combinations and arrangements, and should not be limited thereto. Among them, PWR_OK, +12V, +12V, and GND are output by the second power supply module, and others such as +3.3V, +5VSB, +5V, and +5V are output by the first power supply module.
[0060]
[0061] Table 1
[0062] The first output module 322 has a plurality of first output ports. Please refer to Table 2 below. In the first preferred embodiment, the first output module 322 has 14 first output ports. The outputs of the upper row of first output ports from left to right are +3.3V, +3.3V, GND, +5V, GND, +5V, and GND. The outputs of the lower row of first output ports from left to right are +3.3V, -12V, GND, PS_ON#, GND, GND, and GND. In actual implementation, the first output module 322 can also use other arrangements and combinations, and should not be limited thereto.
[0063]
[0064] Table 2
[0065] The second output module 323 has a plurality of second output ports. Please refer to Table 3 below. In the first preferred embodiment, the second output module 323 has 6 second output ports. The outputs of the upper row of second output ports from left to right are +12V with sense, +12VSB, and PS_ON#. The outputs of the lower row of second output ports from left to right are GND, I_PSU%, and GND. In actual implementation, the second output module 323 can also use other arrangements and combinations, and should not be limited thereto.
[0066]
[0067] Table 3
[0068] The first output module 322 (Table 2) cooperates with the common connection output module 321 (Table 1) to output the first power supply specification of ATX12V, and the second output module 323 (Table 3) cooperates with the common connection output module 321 (Table 1) to output the second power supply specification of ATX12VO.
[0069] The switch module 313 disposed between the first power supply module 311 and the second power supply module 312 is a switching circuit. The switch module 313 is controlled by the detection module 314 to form a conducting state or a cut-off state. When the switch module 313 is in the conducting state, the first power supply module 311 supplies power to the second power supply module 312. When the switch module 313 is in the cut-off state, the first power supply module 311 cannot supply power to the second power supply module 312.
[0070] The detection module 314 is a detection circuit. The detection module 314 is used to detect whether the second output module 323 is in use. Preferably, the detection module 314 is a current detection technology. When the second output module 323 is connected to an electronic device (such as a motherboard), the detection module 314 can detect the output current and determine that the second output module 323 is in use. In actual implementation, the detection module 314 can also use other detection technologies, and should not be limited to this.
[0071] When the detection module 314 detects that the second output module 323 is in use, the detection module 314 controls the switch module 313 to be in the cut-off state. The first power supply module 311 will not obtain any power, and the first power supply module 311 will not operate. Therefore, the first power supply module 311 cannot output the first power supply specification of ATX12V. Please refer to Table 4. In the first preferred embodiment, when the switch module 313 is in the cut-off state, among the multiple common connection output ports of the common connection output module 321, only PWR_OK, +12V, +12V, and GND are output externally, and no power is output from other common connection output ports. In addition, the first output module 322 will not output power either.
[0072]
[0073] Table 4
[0074] When the detection module 314 detects that the second output module 323 is not in use, the detection module 314 controls the switch module 313 to be in the conducting state. The first power supply module 311 supplies power to the second power supply module 312, and the first power supply module 311 outputs the first power supply specification of ATX12V.
[0075] In this preferred embodiment, when the detection module 314 detects one of the plurality of second output ports, the switch module 313 is controlled to be in a conducting state. In actual implementation, when the detection module 314 detects that all of the plurality of second output ports are unused, or when the detection module 314 detects that some of the plurality of second output ports are unused, the switch module 313 is controlled to be in a conducting state, but this should not be taken as a limitation.
[0076] It is worth mentioning that PWR_OK, +12V, +12V, and GND in the common connection output module 321 are the main common connection output ports, which can provide the first power supply specification of ATX12V and can also provide the second power supply specification of ATX12VO, so that the number of interfaces of the common connection output module 321, the first output module 322, and the second output module 323 is reduced to 30, and further reduces the occupied area on the surface of the housing of the intelligent power supply.
[0077] Review Figure 4 , when the power supply specification of an electronic device (such as a motherboard) is the first power supply specification of ATX12V, the first transmission line group 331 is used to transmit power. One end of the first transmission line group 331 is detachably connected to the first output module 322 and the common connection output module 321. The other end of the first transmission line group 331 is provided with the first plug structure 332, and the first plug structure 332 is connected to the electronic device (not shown in the figure), and the first plug structure 332 outputs the first power supply specification of ATX12V (such as Figure 1 ).
[0078] Review Figure 5 , when the power supply specification of an electronic device (such as a motherboard) is the second power supply specification of ATX12VO, the second transmission line group 333 is used to transmit power. One end of the second transmission line group 333 is detachably connected to the second output module 323 and the common connection output module 321. The other end of the second transmission line group 333 is provided with the second plug structure 334, and the second plug structure 334 is connected to the electronic device (not shown in the figure), and the second plug structure 334 outputs the second power supply specification of ATX12VO (such as Figure 2 ).
[0079] Please refer to Figure 6 , which is a second preferred embodiment of an intelligent power supply of the present invention. The second preferred embodiment is substantially the same as the first preferred embodiment, and the same parts will not be described in detail here. The difference is that the transmission unit 33 further includes a third transmission line group 335.
[0080] One end of the third transmission line group 335 is detachably connected to the common connection output module 321, the first output module 322, and the second output module 323. The other end of the third transmission line group 335 is provided with a third plug structure 336 and a fourth plug structure 337. The third plug structure 336 outputs the first power supply specification of ATX12V (such as Figure 1 ), and the fourth plug structure 337 outputs the second power supply specification of ATX12VO (such as Figure 2 ). Among them, the common connection output module 321, the first output module 322, and the second output module 323 can be integrated into a plug structure, which can not only reduce the number of interfaces, but also reduce the plug structure on the housing of the intelligent power supply. When the power supply specification of an electronic device (such as a motherboard) is the first power supply specification of ATX12V, the third plug structure 336 is used. When the power supply specification of an electronic device (such as a motherboard) is the first power supply specification of ATX12VO, the fourth plug structure 337 is used.
[0081] As can be seen from the above description, an intelligent power supply of the present utility model indeed has the following effects:
[0082] 1. Simple circuit design:
[0083] The first power module 311 and the second power module 312 are two separate circuits. The first power module 311 not only uses the +5VDC standby voltage of ATX12V, but also transfers the +12V power supply in ATX12V to the second power module 312, further simplifying the circuit structure of the first power module 311 and reducing the occupation of the internal volume of the intelligent power supply.
[0084] 2. Reduce the number of output interfaces:
[0085] PWR_OK, +12V, +12V, and GND in the common connection output module 321 are the main common connection output ports, which can provide the first power supply specification of ATX12V or the second power supply specification of ATX12VO, so that the number of interfaces of the common connection output module 321, the first output module 322, and the second output module 323 is reduced to 30.
[0086] 3. Reduce energy loss:
[0087] When the detection module 314 detects that the second output module 323 is in use, the detection module 314 controls the switch module 313 to be in a cut-off state, and the first power module 311 will not obtain any power, not only will it not output the first power supply specification of ATX12V, but also can reduce energy loss.
[0088] In summary, in the common connection output module 321, PWR_OK, +12V, +12V, and GND are the main common connection output ports, enabling the +12V power supply in ATX12V to be supplied by the second power supply module 312. This not only simplifies the circuit structure of the first power supply module 311 but also reduces the number of output interfaces. The detection module 314 can detect the usage status of the second output module 323. When the intelligent power supply outputs the second power supply specification of ATX12VO, the power supply of the first power supply module 311 is completely cut off, not only preventing the output of the first power supply specification of ATX12V but also reducing energy consumption. Therefore, the purpose of the present utility model can indeed be achieved.
[0089] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present utility model are all within the protection scope of the present utility model. The protection scope of the present utility model shall be subject to the claims.
