[0002] In existing office integrated power supply systems, AC power is typically distributed from the power grid to different workstations via distribution cabinets. Each workstation is equipped with an AC-DC (Alternating Current-Direct Current) power module to convert the AC power into low-voltage DC power to charge smartphones, tablets, computers, and other smart devices. Simultaneously, each workstation is also equipped with power strips for direct AC power supply to devices requiring AC input.

Multiple AC-DC power modules consume significant power during prolonged standby, resulting in substantial energy waste.

Detailed Implementation

[0029] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0030] In the following description, specific details such as particular system architectures, interfaces, and technologies are presented for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of this application.

[0031] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0032] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, the character " / " generally indicates that the preceding and following related objects are in an "or" relationship. Furthermore, "many" in this application means two or more. Moreover, the term "at least one" in this application means any combination of at least two of any one or more of a plurality of objects. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C. Furthermore, the terms "first," "second," and "third" in this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0033] A typical office integrated DC power supply system distributes high-voltage power from the grid to various office areas via an AC distribution cabinet. Each area is equipped with an air switch for safety protection, and the system is then divided into two circuits. The first circuit uses an AC-DC power module to convert the high-voltage AC power into low-voltage DC power, which is then connected to a Type-C or USB-A interface to power smart devices such as mobile phones, tablets, and computers. The second circuit connects directly to an air switch and then to a power strip, which can be installed at the office workstation to power electrical equipment that requires AC power.

[0034] Conventional integrated DC power supply systems for office use may have the following problems: 1. Type-C and USB-A interfaces can only power smart devices such as mobile phones, tablets, and computers. They cannot charge devices without a charging protocol, making them incompatible with various charging types. 2. Damage to the AC-DC module requires professional repair personnel, making repairs difficult. 3. Since each office area is only equipped with one circuit breaker, a circuit malfunction at one workstation requires a power outage of the entire office area for repairs, which is inconvenient for those working in that area. 4. High-voltage AC output makes the circuits prone to aging and damage, potentially leading to fires and lower safety. 5. Each workstation needs to be equipped with an AC-DC power module, resulting in high energy consumption and significant energy waste when there are many workstations.

[0035] To address the aforementioned issues, this application provides a power supply system for supplying power to various electrical devices, reducing energy consumption, simplifying maintenance, and improving user safety. Please refer to... Figure 1 , Figure 1 This is a schematic diagram of the structure of the first embodiment of the power system of this application. The power system 1 provided in this embodiment includes a first conversion module 11, at least one first power module 12 and at least one second power module 13.

[0036] Specifically, the first terminal of the first conversion module 11 is connected to the power grid and is used to convert the first AC voltage of the power grid into a first DC voltage. The first conversion module 11 can be an AC-DC module. The power grid distributes AC power to the first conversion module 11 through an AC distribution cabinet. The first conversion module 11 converts the AC power into DC power to supply DC power to the first power module 12 and the second power module 13.

[0037] In practical applications, alternating current (AC) is affected by factors such as electromagnetic induction, resistance, and capacitance during transmission, resulting in energy loss. This loss is particularly pronounced over long distances. Therefore, the transmission efficiency of AC is lower than that of direct current (DC). This embodiment uses a first conversion module 11 to convert the first AC voltage to a first DC voltage, effectively improving transmission efficiency and reducing energy consumption. Furthermore, converting the first AC voltage to a first DC voltage before transmission ensures that high-voltage AC is replaced with low-voltage DC, reducing the risk of electric shock and improving user safety, as well as the overall safety of the power system 1.

[0038] The first power module 12 is connected to the second terminal of the first conversion module 11 and is used to convert the first DC voltage into a second DC voltage, which is used to power the first external device. The first power module 12 can be a DC power module. After receiving the first DC voltage, the first power module 12 can adjust the voltage value of the first DC voltage, either increasing or decreasing it to obtain the second DC voltage. The first power module 12 then outputs the second DC voltage to power the first external device.

[0039] It is understandable that the voltage values ​​of the first DC voltage and the second DC voltage are different, and the first external device is an electrical device that requires DC power.

[0040] The second power module 13 is connected to the second terminal of the first conversion module 11 and is used to convert the first DC voltage into a second AC voltage, which is then used to power a second external device. The second external device can be an electrical appliance requiring AC power. By using the second power module 13 to convert the first DC voltage into the second AC voltage to power the second external device, the power system 1 can supply power to both the first external device requiring DC power and the second external device requiring AC power, thus improving the practicality of the power system 1.

[0041] In summary, by setting the first conversion module 11 to convert the first AC voltage of the external power supply into the first DC voltage for transmission, the energy consumption in the power system 1 is reduced, and the area accessible to the user is all under low-voltage DC power, thereby improving the safety of the power system 1.

[0042] The power system 1 may include a first conversion module 11, at least one first power module 12, and at least one second power module 13, thus enabling the power system 1 to supply power to a first external device and a second external device. When a user needs to use the first and second external devices, the power system 1 can simultaneously provide power to the external devices using the first power module 12 and the second power module 13, meeting the power supply requirements of the external devices, improving the practicality of the power system 1, and enhancing the user experience.

[0043] In some embodiments, the power system 1 may include only a first conversion module 11 and at least one first power module 12. The power system 1 can supply power to a first external device, and since the power system 1 does not include a second power module 13, the number of components in the power system 1 can be reduced, thus lowering energy consumption and component costs. Simultaneously, reducing the number of high-voltage AC output ports (since the second power module 13 outputs a second AC voltage, its output port is a high-voltage AC output port) improves the safety of users using the power system 1 to power external devices.

[0044] In other embodiments, the power system 1 may include only the first conversion module 11 and at least one second power module 13, so that the power system 1 can supply power to the second external device. Since the power system 1 does not have the first power module 12, the number of devices in the power system 1 is reduced, and energy consumption is reduced.

[0045] It is understandable that, in practical applications, users can set the number of the first power module 12 and the second power module 13 in the power system 1 according to their needs, and this application does not impose any restrictions on this.

[0046] Optionally, please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of the power supply system of the second embodiment of this application. The first power supply module 12 includes a first protection module 121, a second conversion module 122, and a first interface module 123.

[0047] The second conversion module 122 is detachably disposed between the first protection module 121 and the first interface module 123. The first end of the second conversion module 122 is connected to the second end of the first conversion module 11 through the first protection module 121. The second end of the second conversion module 122 is connected to the first interface module 123. The second conversion module 122 is used to convert the first DC voltage to the second DC voltage. The first interface module 123 is connected to the first external device.

[0048] The second conversion module 122 can be a DC-DC (Direct Current-Direct Current) module, which can convert DC voltage to another DC voltage. Specifically, the second conversion module 122 is used to convert the first DC voltage into a second DC voltage with a higher voltage value or a lower voltage value, which can be determined by the power supply voltage required by the first external device. Since the first interface module 123 is connected to the second terminal of the second conversion module 122, and the first external device is connected to the first interface module 123, the second conversion module 122 can output the second DC voltage to the first external device through the first interface module 123 to power the first external device.

[0049] It is understood that the specific relative relationship between the voltage values ​​of the second DC voltage and the first DC voltage can be determined by the power supply voltage required by the first external device, and this application does not impose any restrictions on this.

[0050] In one embodiment, the first protection module 121 can be a hot-swappable power protection module. The hot-swappable function allows users to remove and replace damaged components such as hard drives, power supplies, or circuit boards without shutting down the system or cutting off the power, thereby improving the system's ability to recover from disasters promptly, its scalability, and its flexibility. This embodiment sets the first protection module 121 before the second conversion module 122 to allow for the detachable connection of the second conversion module 122. Therefore, when the second conversion module 122 malfunctions or is damaged, the user can replace it without professional personnel, reducing the difficulty of repairing the first power module 12. Furthermore, the second conversion module 122 can be replaced while powered on without affecting the circuitry in other areas, improving the user experience of the power system 1.

[0051] Optionally, the first interface module 123 can be at least one of a Type-C interface, a USB-A interface, an HDMI interface, a network interface, and a DC interface. The Type-C and USB-A interfaces can connect to smart devices such as mobile phones, tablets, and computers; the HDMI interface can connect to extended displays; the network interface can connect to network devices; and the DC interface can connect to power tools. The second conversion module 122 then supplies power to the connected external device through the corresponding interface, improving the compatibility of the power system 1, enabling a greater variety of power supply devices, enhancing the practicality of the power system 1, and improving the user experience.

[0052] The DC interface can also be customized according to the interface type required by the power tool to meet the power supply needs of devices with different interfaces.

[0053] In other embodiments, the first interface module 123 may also include other types of interfaces. The specific interface types and / or the specific number of a certain interface type can be set according to the user's needs. This application does not impose specific limitations on this.

[0054] Optionally, the second power module 13 includes a second protection module 131, a third conversion module 132, and a second interface module 133.

[0055] The third conversion module 132 is detachably disposed between the second protection module 131 and the second interface module 133. The first end of the third conversion module 132 is connected to the second end of the first conversion module 11 through the second protection module 131, and the second end of the third conversion module 132 is connected to the second interface module 133. The third conversion module 132 is used to convert the first DC voltage into the second AC voltage, and the second interface module 133 is connected to the second external device.

[0056] Specifically, the third conversion module 132 can be a DC-AC (Direct Current-Alternating Current) module to convert the first DC voltage into a second AC voltage. The second interface module 133 is connected to the second terminal of the third conversion module 132, and the second external device is connected to the second interface module 133. Thus, the third conversion module 132 can supply the second AC voltage to the second external device through the second interface module 133 to power the second external device, thereby improving the practicality of the power supply system 1. It is understood that the voltage values ​​of the first AC voltage and the second AC voltage can be equal or unequal; this application does not impose specific limitations in this regard.

[0057] In one embodiment, the second interface module 133 can be a power strip, socket, or other device, and the second protection module 131 can be the same hot-swappable power protection module as the first protection module 121, allowing the third conversion module 132 to be detachably connected between the second protection module 131 and the second interface module 133. This allows the third conversion module 132 to be replaced automatically when it is abnormal or damaged, reducing maintenance difficulty and improving the practicality of the power system 1.

[0058] In summary, in this embodiment, the first power module 12 includes a first protection module 121, a second conversion module 122, and a first interface module 123. The second conversion module 122 converts a first DC voltage into a second DC voltage, and then transmits the second DC voltage to a first external device through the first interface module 123, enabling the power system 1 to supply power to the first external device. The first protection module 121 protects the circuitry in the first power module 12, allowing the second conversion module 122 to be detachably connected between the first protection module 121 and the first interface module 123, reducing the maintenance difficulty of the power system 1 and improving the user experience. Furthermore, the first interface module 123 includes multiple interface types, enabling connection to various types of first external devices, allowing the power system 1 to supply power to various types of first external devices, further improving the practicality of the power system 1.

[0059] The second power module 13 includes a second protection module 131, a third conversion module 132, and a second interface module 133. The third conversion module 132 converts a first DC voltage into a second AC voltage, and then transmits the second AC voltage to a second external device through the second interface module 133, enabling the power system 1 to supply power to the second external device. The second protection module 131 protects the circuitry in the second power module 13, allowing the third conversion module 132 to be detachably connected between the second protection module 131 and the second interface module 133, reducing the maintenance difficulty of the power system 1 and improving the user experience.

[0060] In practical applications, direct current (DC) also exhibits a high advantage in conversion efficiency. Specifically, DC conversion is simpler and more efficient because it does not require frequency and phase conversion. Alternating current (AC), on the other hand, requires multiple voltage and frequency conversions during generation, transmission, and consumption, resulting in energy losses. Therefore, the conversion efficiency of AC to DC is lower than that of DC to DC and DC to AC. This embodiment, by setting a first conversion module 11 to convert a first AC voltage to a first DC voltage, then setting a first power module 12 to convert the first DC voltage to a second DC voltage to power a first external device, and setting a second power module 13 to convert the first DC voltage to a second AC voltage to power a second external device, significantly improves the voltage conversion efficiency compared to existing technologies that require multiple AC-DC modules to convert AC to DC. This higher conversion efficiency effectively reduces energy consumption in the power system 1.

[0061] In one embodiment, since the second conversion module 122 is detachably connected between the first protection module 121 and the first interface module 123, and the third conversion module 132 is detachably connected between the second protection module 131 and the second interface module 133, the power system 1 is provided with a first power module 12 and a second power module 13. When the user no longer needs to use the second external device for work or the number of first external devices requiring power increases, the user can replace the third conversion module 132 in the second power module 13 with the second conversion module 122, thereby increasing the number of first power modules 12 in the power system 1. This provides the user with more interfaces for first external devices, enabling the user to power more first external devices and improving the user experience of the power system 1. It is understood that the user can also replace the second conversion module 122 in the first power module 12 with the third conversion module 132 as needed, and this application does not limit this.

[0062] The second conversion module 122 and the third conversion module 132 can be modules of the same size.

[0063] In another embodiment, as described above, the power system 1 may only have a first power module 12. If the power system 1 only has a first power module 12 to power the first external device, but the user needs to use a second external device to work, and the power system 1 also needs to power the second external device, the user does not need to replace the power system 1 or move to another area where a second power module 13 is set up to work. The user only needs to replace the second conversion module 122 in the first power module 12 with a third conversion module 132 to output a second AC voltage to power the second external device, thereby improving the practicality of the power system 1 and enhancing the user's experience with the power system 1.

[0064] In another embodiment, as described above, the power system 1 may only have a second power module 13. If the power system 1 only has a second power module 13, and the user needs to use the first external device to work, and the power system 1 also needs to supply power to the first external device, the user may replace the third conversion module 132 in the second power module 13 with the second conversion module 122 to output a second DC voltage to power the first external device.

[0065] Alternatively, please continue reading Figure 3 , Figure 3 This is a schematic diagram of the power supply system according to the third embodiment of this application. The power supply system 1 provided in this embodiment also includes a protection switch 14 and a connection module 15.

[0066] The first end of the protection switch 14 is connected to an external power source, and the second end of the protection switch 14 is connected to the first end of the connection module 15. The second end of the connection module 15 is connected to the first power module 12 and the second power module 13. The first conversion module 11 is detachably installed on the connection module 15, and the first end of the connection module 15 and the second end of the connection module 15 are connected through the first conversion module 11.

[0067] Specifically, the protective switch 14 can be the air switch circuit breaker mentioned above, to protect the subsequent circuits in the power supply system 1. The connection module 15 can be a power strip. When the first conversion module 11 is not installed on the connection module 15, the first end and the second end of the connection module 15 are not connected, and there is an open circuit between the external power supply and the first power module 12 and the second power module 13. After the first conversion module 11 is installed on the connection module 15, the first end and the second end of the connection module 15 are connected through the first conversion module 11. That is, the first AC voltage of the external power supply will enter the first conversion module 11 through the first end of the connection module 15. After the first AC voltage is converted into a first DC voltage, the first conversion module 11 will deliver the first DC voltage to the first power module 12 and the second power module 13 through the second end of the connection module 15.

[0068] By detachably installing the first conversion module 11 on the connection module 15, the user can replace the first conversion module 11 when it is abnormal or damaged, without the need for maintenance personnel, thus further reducing the maintenance difficulty of the power system 1.

[0069] The connection module 15 may be equipped with multiple first conversion modules 11, each of which can provide a first DC voltage to the first power module 12 and the second power module 13.

[0070] For example, if the output power of the first conversion module 11 is 1000W, the output power of the second conversion module 122 in the first power module 12 is 200W, and the output power of the third conversion module 132 in the second power module 13 is 300W, then one first conversion module 11 can provide the first DC voltage to two first power modules 12 and two second power modules 13. Alternatively, one first conversion module 11 can supply the first DC voltage to five first power modules 12. Or, one first conversion module 11 can supply the first DC voltage to three second power modules 13.

[0071] In the case where the power system 1 needs to include 10 first power modules 12 and 10 second power modules 13, then the connection module 15 can be equipped with 5 first conversion modules 11 to supply power to 20 first power modules 12. Compared with the prior art which requires multiple AC-DC modules, the number of first conversion modules 11 in this application is greatly reduced, effectively reducing the energy consumption of the power system 1.

[0072] In other embodiments, the output power of the first conversion module 11, the second conversion module 122, and the third conversion module 132 may also be other values. They can be freely combined based on the actual values ​​of the output power of each conversion module, and this application does not impose specific restrictions on this.

[0073] Alternatively, please continue reading Figure 4 , Figure 4 This is a schematic diagram of the structure of the power system of the fourth embodiment of this application. The power system 1 provided in this embodiment of the application also includes a telescopic cable module 16. The telescopic cable module 16 is detachably connected to the first interface module 123, and the first interface module 123 supplies power to the first external device through the telescopic cable module 16.

[0074] The retractable cable module 16 is a module that allows the data cable to stretch and spring back using a spring-loaded mechanism. When the first external device and the first interface module 123 are far apart, the user can use the retractable cable module 16 to connect the first interface module 123 to the first external device. The first interface module 123 then supplies power to the first external device through the retractable cable module 16. This allows for diverse placement options for the first power module 12, ensuring that its placement is not limited by the location of the first external device, thus improving the user experience of the power system 1.

[0075] Optionally, the power system 1 further includes a voltage decoy module 17, which is detachably connected to the first interface module 123 and is used to enable the second conversion module 122 to output a third DC voltage through the first interface module 123 to power the third external device.

[0076] The voltage deception module 17 is designed to trick the charger or power supply into outputting a higher voltage by simulating the needs of the device. After the voltage deception module 17 is connected to the first interface module 123, it can trick the second conversion module 122 into outputting a specific voltage value to power a third external device. That is, the third DC voltage is a second DC voltage with a specific value, and the third external device is a first external device with a specific supply voltage. This improves the power supply system 1's ability to power different external devices and enhances its practicality.

[0077] Optional, please refer to Figure 5 , Figure 5 This is a structural schematic diagram of the fifth embodiment of the power supply system of this application. The power supply system 1 of this embodiment also includes a display module 18, which can be connected to the first power module 12 and is used to display the real-time output parameters of the first power module 12; and the display module 18 can be connected to the second power module 13 and is used to display the real-time output parameters of the second power module 13.

[0078] Specifically, the display module 18 can be connected to the second conversion module 122 and the third conversion module 132. The display module 18 can be a display screen to display the real-time output voltage, real-time output current and real-time output power of the output ports of the second conversion module 122 and the third conversion module 132, so that users can intuitively obtain the operating efficiency of the first power module 12 and the second power module 13.

[0079] Furthermore, the display module 18 can also display information about the connected first or second external device. For example, if the mobile phone is connected to the second conversion module 122 via a Type-C interface and the second conversion module 122 outputs current to power the mobile phone, the display module 18 can also display the mobile phone's battery level, estimated remaining charging time, etc., thereby improving the interaction function between the power system 1 and the user. This application does not impose any limitations on this.

[0080] In another embodiment, the display module 18 can also be an LED light. When the second conversion module 122 and the third conversion module 132 are operating normally, the LED light can display green. When the second conversion module 122 and the third conversion module 132 are malfunctioning, the corresponding LED light can display red to remind the user that the second conversion module 122 and / or the third conversion module 132 are malfunctioning and need to be replaced.

[0081] In other embodiments, the display module 18 may also have other structures, and this application does not impose specific limitations on them.

[0082] In summary, the power system 1 provided in this application converts the first AC voltage (e.g., 96-264V) of the power grid (e.g., 96-264V) into a first DC voltage for transmission by setting a first conversion module 11, and then converts the first DC voltage (e.g., 48V) into a second DC voltage using a first power module 12 based on user needs, and converts the first DC voltage into a second AC voltage using a second power module 13. This reduces energy consumption in the power system 1, ensures that the area accessible to the user is all low-voltage DC, and improves the safety of the power system 1.

[0083] Furthermore, the first conversion module 11, the second conversion module 122, and the third conversion module 132 are all detachable and replaceable modules. When the first conversion module 11, the second conversion module 122, or the third conversion module 132 malfunctions in the power system 1, the user can replace the first conversion module 11, the second conversion module 122, or the third conversion module 132, thereby reducing the maintenance difficulty of the power system 1 and improving the user's experience with the power system 1.

[0084] The power system 1 provided in this application can be applied to an office area. The first power module 12 and the second power module 13 are installed at corresponding workstations. The office area may include a first workstation, a second workstation, and a third workstation. If a user at the first workstation uses a first external device to work, then only the first power module 12 can be installed at the first workstation. If a user at the second workstation uses a second external device to work, then only the second power module 13 can be installed at the second workstation. If a user at the third workstation uses both the first and second external devices to work, then both the first power module 12 and the second power module 13 can be installed at the third workstation.

[0085] The third workstation can have two mounting positions for installing the first power module 12 and the second power module 13. Similarly, both the first and second workstations can have two mounting positions. On the first workstation, one mounting position will have the first power module 12 installed, while the other will be idle. On the second workstation, one mounting position will have the second power module 13 installed, while the other will be idle. When a user at the first workstation needs to operate the second external device, they can install the second power module 13 in the idle mounting position to power it. Conversely, when a user at the second workstation needs to operate the first external device, they can install the first power module 12 in the idle mounting position to power it.

[0086] Alternatively, the first power module 12 can be installed in both mounting positions at the first workstation to provide more power interfaces for the first external device. The second power module 13 can be installed in both mounting positions at the second workstation to provide more power interfaces for the second external device.

[0087] The first conversion module 11 converts the AC power from the power grid into DC power for transmission, ensuring that all areas in contact with the user are powered by low-voltage DC, thus improving user safety. Furthermore, the second power module 13 is only installed at workstations where the user needs to operate the second external device, reducing the number of high-voltage AC output ports in the office area and further enhancing the safety of the power system 1 for the user.

[0088] Meanwhile, the detachable and replaceable configuration of the first power module 12 and the second power module 13 in the office area can meet the power supply needs of users for different external devices, improve the practicality of the power system 1 in the office area, and enhance the user experience of the power system 1.

[0089] This application also provides an integrated office power supply device A, please refer to [link / reference]. Figure 6 , Figure 6This is a schematic diagram of an embodiment of the integrated office power supply device A of this application. The integrated office power supply device A provided in this application includes at least one office workstation and a power system 1 as described above. The first power module 12 and the second power module 13 of the power system 1 are disposed on the corresponding office workstation and are used to supply power to external devices located at the office workstation.

[0090] Specifically, each office workstation may be equipped with only one first power module 12, while a second power module 13 may be installed at workstations with external devices that require AC power, in order to reduce the number of AC power output terminals and improve user safety.

[0091] Alternatively, each office workstation can be equipped with a first power module 12 and a second power module 13 to meet the power supply needs of different external devices at the workstation and improve the user experience of the integrated office power supply device A.

[0092] Optionally, the office integrated power supply device A also includes at least one housing 2, specifically a receiving cavity, and each housing is set on a corresponding office workstation. The receiving cavity is used to accommodate the first power module 12 and the second power module 13 to isolate the first power module 12 and the second power module 13, improve the aesthetics of the office workstation, and further enhance the user's experience of using the office integrated power supply device A.

[0093] The connection module 15 and the first conversion module 11 in the power system 1 can be installed on the wall of the office area and connected to the first power module 12 and the second power module 13 installed inside the housing 2 on the office workstation via wires. A fixing plate can also be installed on the desktop of the office workstation for fixing the housing 2.
