[0001] This application relates to the technical field of power supply technology, and particularly relates to a power supply system and an office integrated power supply device.

Background Art

[0002] In an existing office integrated power supply system, usually, alternating current power is distributed from the power grid to each office desk through a distribution board (distribution sub-board). Each office desk is equipped with an AC-DC (Alternating Current - Direct Current) power module for converting alternating current power into direct current low voltage to charge smart devices such as smartphones, tablets, and computers. At the same time, each office desk is also equipped with a power strip, which supplies power to devices that require alternating current power input by directly supplying alternating current power.

[0003] However, when the number of office desks in an office area is large, it is necessary to arrange one AC-DC power module for each office desk. When multiple AC-DC power modules are in a standby state for a long time, the power consumption becomes very large, resulting in a great waste of energy. Furthermore, if there are too many power taps for high-voltage alternating current output, they will deteriorate over a long period of use, making it easy to cause a fire and reducing safety.

[0015] The embodiments of this application will be described in detail below with reference to the attached drawings.

[0016] In the following description, specific details such as particular system structures, interfaces, and technologies are provided for illustrative purposes only and are not limiting, in order to facilitate a full understanding of this application.

[0017] In this application, “Embodiment” means that certain features, structures, or characteristics described in relation to an embodiment may be included in at least one embodiment of this application. The occurrence of this phrase in various parts of this specification does not necessarily refer to the same embodiment, nor does it refer to mutually exclusive, independent, or substitutable embodiments.

[0019] A typical office-integrated DC power system distributes power from a high-voltage power grid to various office areas via an AC distribution panel, with one air switch installed in each area for safety protection. The system is then divided into two circuits. The first circuit uses an AC-DC power module to convert the high-voltage AC power to low-voltage DC power. It converts to a power source and combines with a Type-C or USB-A interface to power smart devices such as mobile phones, tablets, and computers. The second circuit, after passing through a circuit breaker, connects directly to a power strip and is installed directly on each office desk to supply power to electrical devices that require AC power.

[0020] Here, general office integrated DC power supply systems have the following problems. 1. The Type-C or USB-A interface can only supply power to smart devices such as mobile phones, tablets, and computers, and devices without a charging protocol cannot be charged, so there is no compatibility with various charging types. 2. When the AC-DC module is damaged, a professional repair person is required, making the repair difficult. 3. Since only one breaker is installed in each office area, if a circuit fails at one office desk, it is necessary to cut off the power supply for the entire office area for repair, which is inconvenient for the workers in that area. 4. Due to the high-voltage AC output, the circuit is prone to deterioration and damage, there is a risk of fire, and the safety is low. 5. Since an AC-DC power module needs to be installed at each office desk, when the number of office desks is large, the power consumption increases, causing a great deal of energy waste.

[0021] Based on the above problems, the present application provides a power supply system that supplies power to various electrical devices, reduces energy consumption, lowers the maintenance difficulty, and improves the user's usage safety. Referring to FIG. 1, FIG. 1 is a schematic structural diagram of the first embodiment of the power supply system of the present application. The power supply 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.

[0022] Specifically, the first end 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. Here, the first conversion module 11 may be an AC-DC module. The power grid distributes an AC power supply to the first conversion module 11 through an AC distribution sub-panel, and the first conversion module 11 converts the AC power supply into a DC power supply and supplies the DC power supply to the first power module 12 and the second power module 13.

[0023] In actual applications, alternating current power is affected by factors such as electromagnetic induction, resistance, and capacitance during transmission, resulting in certain energy losses. Especially in long-distance power transmission, the losses of alternating current power transmission increase significantly. As a result, the transmission efficiency of alternating current power is lower than that of direct current power. In this embodiment, the first conversion module 11 first converts the first alternating current voltage into the first direct current voltage, thereby effectively improving the voltage transmission efficiency and reducing energy consumption. At the same time, by transmitting after converting the first alternating current voltage into the first direct current voltage, the high-voltage alternating current is converted into low-voltage direct current, making all the ranges that users can contact be low-voltage direct current, reducing the risk of electric shock to users, and improving the use safety of users and the safety of the entire power supply system 1.

[0024] The first power module 12 is connected to the second end of the first conversion module 11 and is used to convert the first direct current voltage into the second direct current voltage. The second direct current voltage is used to supply power to the first external device. Here, the first power module 12 may be a direct current power module. After receiving the first direct current voltage, the first power module 12 can adjust the voltage value of the first direct current voltage, increase or decrease the voltage value of the first direct current voltage to obtain the second direct current voltage, and then the first power module 12 outputs the second direct current voltage to supply power to the first external device.

[0025] As can be understood, the voltage values of the first direct current voltage and the second direct current voltage are different, and the first external device is an electrical device that requires a direct current power supply.

[0026] The second power module 13 is connected to the second end of the first conversion module 11 and is used to convert the first DC voltage to a second AC voltage, which is used to supply power to a second external device. Here, the second external device may be an electrical device that requires AC power supply. By configuring the second power module 13 to convert the first DC voltage to a second AC voltage and supply power to the second external device, the power system 1 can supply power to both the first external device that requires DC power supply and the second external device that requires AC power supply, thereby improving the practicality of the power system 1.

[0027] In summary, by configuring the first conversion module 11 to convert the first AC voltage of the external power supply to a first DC voltage for transmission, the energy consumption of the power supply system 1 is reduced, and the safety of the power supply system 1 is improved by making all areas accessible to the user low-voltage DC power.

[0028] Here, the power supply system 1 may include a first conversion module 11, at least one first power supply module 12, and at least one second power supply module 13, thereby enabling the power supply system 1 to supply power to both the first and second external devices. When a user works with the first and second external devices, the devices can be powered by simultaneously installing the first power supply module 12 and the second power supply module 13 in the power supply system 1, thereby meeting the power supply needs of the external devices, improving the practicality of the power supply system 1, and enhancing the user experience with the power supply system 1.

[0029] In some embodiments, the power supply system 1 may comprise only a first conversion module 11 and at least one first power supply module 12, and the power supply system 1 can supply power to a first external device. Furthermore, since the power supply system 1 does not include a second power supply module 13, the number of components in the power supply system 1 can be reduced, thereby reducing energy consumption and component costs. At the same time, reducing the number of high-voltage AC output ports (since the second power supply module 13 outputs a second AC voltage, the output ports of the second power supply module 13 become high-voltage AC output ports) improves the safety of users who supply power to external devices using the power supply system 1.

[0030] In other embodiments, the power supply system 1 may comprise only the first conversion module 11 and at least one second power supply module 13, thereby enabling the power supply system 1 to supply power to a second external device. Since the power supply system 1 does not include the first power supply module 12, the number of components in the power supply system 1 is reduced, and energy consumption is lowered.

[0031] To make it easier to understand, in actual application, the user can set the number of first power modules 12 and second power modules 13 in the power system 1 as needed, and this application is not limited thereto.

[0032] Referencing optionally to Figure 2, Figure 2 is a schematic diagram of the structure of a second embodiment of the power supply system of the present application. The first power supply module 12 comprises a first protection module 121, a second conversion module 122, and a first interface module 123.

[0033] The second conversion module 122 is detachably positioned 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 via the first protection module 121, and 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 a first DC voltage to a second DC voltage, and the first interface module 123 is connected to a first external device.

[0034] Here, the second conversion module 122 may be a DC-DC (Direct Current-Direct Current) module capable of converting one DC voltage to another. Specifically, the second conversion module 122 is used to convert the first DC voltage to a second DC voltage having a higher or lower voltage value, which can be determined according to the power supply voltage required by the first external device. Since the first interface module 123 is connected to the second end 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 via the first interface module 123 and supply power to the first external device.

[0035] To make it clear, the specific relative relationship between the voltage value of the second DC voltage and the voltage value of the first DC voltage can be determined by the power supply voltage required by the first external device, and this application is not limited thereto.

[0036] In one embodiment, the first protection module 121 may be a hot-swappable power protection module. Here, the hot-swappable function allows the user to remove and replace a faulty component such as a hard disk, power supply, or board card without shutting down the system or cutting off the power, improving the system's ability to recover quickly in the event of a disaster, as well as its expandability and flexibility. In this embodiment, the first protection module 121 is installed in front of the second conversion module 122, enabling a detachable connection of the second conversion module 122. This allows the user to replace the second conversion module 122 themselves without requiring a specialist if the second conversion module 122 fails or is damaged, reducing the difficulty of repairing the first power module 12. Furthermore, since the second conversion module 122 can be replaced while powered on and does not affect the circuits in other areas, the user experience with the power system 1 is improved.

[0037] Optionally, the first interface module 123 may be at least one of a Type-C interface, a USB-A interface, an HDMI interface, a network interface, and a DC interface. Here, the Type-C and USB-A interfaces can be connected to smart devices such as mobile phones, tablets, and computers; the HDMI interface can be connected to an extended display, etc.; the network interface can be connected to a network device; and the DC interface can be connected to a power tool, etc. This allows the second conversion module 122 to supply power to external devices connected via the corresponding interfaces, improving the compatibility of the power system 1, enabling diversification of the types of power devices, improving the practicality of the power system 1, and enhancing the user experience of the power system 1.

[0038] Here, the DC interface can be customized to match the interface type required by the power tool, and can meet the power supply needs of devices with different interfaces.

[0039] In other embodiments, the first interface module 123 may also include other types of interfaces, and specific interface types and / or specific quantities of specific interface types, etc., including the first interface module 123 can be set based on user needs, and this application is not specifically limited thereto.

[0040] Selectively, the second power supply module 13 includes a second protection module 131, a third conversion module 132, and a second interface module 133.

[0041] Here, the third conversion module 132 is detachably positioned 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 via 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 a first DC voltage to a second AC voltage, and the second interface module 133 is connected to a second external device.

[0042] Specifically, the third conversion module 132 may be a DC-AC (Direct Current-Alternating Current) module, which converts a first DC voltage to a second AC voltage. The second interface module 133 is connected to the second end of the third conversion module 132, and the second external device is connected to the second interface module 133, thereby enabling the third conversion module 132 to supply the second AC voltage to the second external device via the second interface module 133, thereby supplying power to the second external device and improving the practicality of the power supply system 1. It is understood that the voltage values ​​of the first AC voltage and the voltage values ​​of the second AC voltage may be equal or different, but this application is not particularly limited thereto.

[0043] In one embodiment, the second interface module 133 can be a device such as a power strip or outlet. The second protection module 131 can be the same hot-swappable power protection module as the first protection module 121, which allows for a detachable connection between the third conversion module 132 and the second interface module 133. If the third conversion module 132 malfunctions or fails, the user can replace it themselves, reducing the difficulty of maintenance and improving the practicality of the power system 1.

[0044] In summary, in this embodiment, the first power module 12 comprises a first protection module 121, a second conversion module 122, and a first interface module 123. The second conversion module 122 is used to convert a first DC voltage to a second DC voltage, thereby allowing the second conversion module 122 to supply the second DC voltage to a first external device via the first interface module 123, and enabling the power system 1 to supply power to the first external device. The first protection module 121 is used to protect the circuitry within the first power module 12, and allows for a detachable connection between the first protection module 121 and the first interface module 123 of the second conversion module 122, reducing the difficulty of maintenance of the power system 1 and improving the user experience of the power system 1. Furthermore, the first interface module 123 has multiple types of interfaces, enabling connection with various types of first external devices, allowing the power system 1 to supply power to multiple types of first external devices, further improving the practicality of the power system 1.

[0045] The second power supply module 13 comprises a second protection module 131, a third conversion module 132, and a second interface module 133. The third conversion module 132 is used to convert the first DC voltage to a second AC voltage, thereby enabling the third conversion module 132 to supply the second AC voltage to a second external device via the second interface module 133, and the power supply system 1 to supply power to the second external device. The second protection module 131 is used to protect the circuitry within the second power supply module 13, thereby allowing a detachable connection between the second protection module 131 and the second interface module 133 of the third conversion module 132, reducing the difficulty of maintenance of the power supply system 1 and improving the user experience of the power supply system 1.

[0046] In practical applications, DC power also exhibits a similar advantage in terms of conversion efficiency. Here, the conversion process for DC power is simpler and more efficient because it does not require frequency and phase conversion. On the other hand, AC power requires multiple voltage and frequency conversions during generation, transmission, and consumption, and all of these processes result in energy loss. Therefore, the conversion efficiency from AC power to DC power is lower than the conversion efficiency from DC power to DC power, and from DC power to AC power. In this embodiment, a first conversion module 11 is provided to first convert the first AC voltage to a first DC voltage, then a first power supply module 12 is provided to convert the first DC voltage to a second DC voltage to supply power to a first external device, and a second power supply module 13 is provided to convert the first DC voltage to a second AC voltage to supply power to a second external device. Compared to conventional technology, which requires the installation of multiple AC-DC modules to achieve conversion from AC power to DC power, the voltage conversion efficiency of the power supply system 1 provided in this application is significantly improved, the conversion efficiency of the power supply system 1 is improved, and the energy consumption of the power supply system 1 is effectively reduced.

[0047] In one embodiment, 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. Therefore, if the power supply system 1 is equipped with the first power supply module 12 and the second power supply module 13, and the user no longer needs to work with a second external device, or if the number of first external devices requiring power increases, the user can replace the third conversion module 132 in the second power supply module 13 with the second conversion module 122. This increases the number of first power supply modules 12 in the power supply system 1, providing the user with more interfaces for first external devices, allowing the user to power more first external devices, and improving the user experience with the power supply system 1. To be understood, the user can also replace the second conversion module 122 in the first power supply module 12 with the third conversion module 132 if necessary, but this application is not limited thereto.

[0048] Here, the second conversion module 122 and the third conversion module 132 may be modules of the same size.

[0049] In another embodiment, as described above, the power supply system 1 may consist only of the first power module 12. When the power supply system 1 consists only of the first power module 12 and supplies power to the first external device, if the user needs to use the second external device to perform their work, and the power supply system 1 also needs to supply power to the second external device, the user does not need to replace the power supply system 1 or move to another area where the second power module 13 is installed to perform their work. Instead, they can simply replace the second conversion module 122 in the first power module 12 with the third conversion module 132 to output a second AC voltage and supply power to the second external device, thereby improving the practicality of the power supply system 1 and enhancing the user experience with the power supply system 1.

[0050] In another embodiment, as described above, only the second power module 13 may be installed in the power system 1. If only the second power module 13 is installed in the power system 1, and the user needs to work with the first external device, and the power system 1 also needs to supply power to the first external device, the user can replace the third conversion module 132 in the second power module 13 with the second conversion module 122, which will output a second DC voltage and supply power to the first external device.

[0051] Selectively referring to Figure 3, which is a schematic diagram of the structure of a power supply system according to a third embodiment of the present application. The power supply system 1 of this embodiment further comprises a protective switch 14 and a connection module 15.

[0052] The first end of the protective switch 14 is connected to an external power supply, the second end of the protective 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 attached to the connection module 15, and the first end and the second end of the connection module 15 are connected via the first conversion module 11.

[0053] Specifically, the protective switch 14 may be the aforementioned circuit breaker and is used to protect the downstream circuit of the power supply system 1. The connection module 15 may be a power tap. If the first conversion module 11 is not attached to the connection module 15, the first end and the second end of the connection module 15 are not connected, and an open circuit is formed between the external power supply and the first power module 12 and the second power module 13. After the first conversion module 11 is attached to the connection module 15, the first end and the second end of the connection module 15 are connected via the first conversion module 11, that is, the first AC voltage of the external power supply is input to the first conversion module 11 via the first end of the connection module 15, and after the first AC voltage is converted to a first DC voltage, the first conversion module 11 supplies the first DC voltage to the first power module 12 and the second power module 13 via the second end of the connection module 15.

[0054] Since the first conversion module 11 is detachably attached to the connection module 15, if the first conversion module 11 malfunctions or is damaged, the user can replace the first conversion module 11 without the need for a repair technician, further reducing the difficulty of maintaining the power system 1.

[0055] Here, the connection module 15 may be provided with multiple first conversion modules 11. Each first conversion module 11 can supply a first DC voltage to the first power supply module 12 and the second power supply module 13.

[0056] 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 supply 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. Alternatively, one first conversion module 11 can supply the first DC voltage to three second power modules 13.

[0057] If the power supply system 1 includes 10 first power modules 12 and 10 second power modules 13, then 5 first conversion modules 11 can be installed in the connection module 15 to supply power to 20 first power modules 12. Compared to conventional technology that requires multiple AC-DC modules, the number of first conversion modules 11 in this application is significantly reduced, effectively reducing the energy consumption of the power supply system 1.

[0058] In other embodiments, the output power of the first conversion module 11, the output power of the second conversion module 122, and the output power of the third conversion module 132 may be other values. They can be freely combined based on the actual output power values ​​of each conversion module, and this application is not specifically limited thereto.

[0059] Selectively referring to Figure 4, which is a schematic diagram of the structure of a power supply system according to a fourth embodiment of the present application. The power supply system 1 provided in this embodiment also includes a telescopic module 16. The telescopic module 16 is detachably connected to a first interface module 123, which supplies power to a first external device via the telescopic module 16.

[0060] Here, the telescopic module 16 is a module that can expand and contract data lines using a coil spring, and when the first external device is far from the first interface module 123, the user can use the telescopic module 16 to connect the first interface module 123 to the first external device, thereby allowing the first interface module 123 to supply power to the first external device via the telescopic module 16. The first power supply module 12 can be installed in various locations, and the placement of the first power supply module 12 is not limited by the placement of the first external device, thereby improving the user experience of the power supply system 1.

[0061] Selectively, the power supply system 1 further comprises a voltage induction module 17. The voltage induction module 17 is detachably connected to the first interface module 123 and is used to cause the second conversion module 122 to output a third DC voltage via the first interface module 123 to supply power to a third external device.

[0062] Here, the voltage induction module 17 is a module that tricks a charger or power supply into outputting a high voltage by simulating the needs of a device. After the voltage induction module 17 is connected to the first interface module 123, the voltage induction module 17 can induce the second conversion module 122 to output a voltage of a specific value, thereby supplying power to the third external device. That is, the third DC voltage is the second DC voltage having a specific voltage value, and the third external device is the first external device having a specific supply voltage. This improves the power supply system 1's ability to supply power to different external devices and enhances the practicality of the power supply system 1.

[0063] Selectively referring to Figure 5, which is a schematic diagram of the structure of a fifth embodiment of the power supply system of the present application. The power supply system 1 of this embodiment also includes a display module 18. The display module 18 can be connected to a first power supply module 12 and used to display the real-time output parameters of the first power supply module 12, or the display module 18 can be connected to a second power supply module 13 and used to display the real-time output parameters of the second power supply module 13.

[0064] Specifically, the display module 18 can be connected to the second conversion module 122 and the third conversion module 132. The display module 18 may also be a display screen that can 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, thereby allowing the user to intuitively understand the operating efficiency of the first power supply module 12 and the second power supply module 13.

[0065] Furthermore, the display module 18 can also display information about the connected first or second external device. For example, if a mobile phone is connected to the second conversion module 122 via a Type-C interface and the second conversion module 122 supplies power to the mobile phone by outputting current, the display module 18 can display the mobile phone's battery level and estimated remaining charging time, improving the interaction between the power system 1 and the user, and this application is not limited to this function.

[0066] In another embodiment, the display module 18 may be an LED light. When the second conversion module 122 and the third conversion module 132 are operating normally, the LED light displays green, and when the second conversion module 122 and the third conversion module 132 are faulty, the corresponding LED light displays red, thereby notifying the user that the second conversion module 122 and / or the third conversion module 132 are faulty and need to be replaced.

[0067] In other embodiments, the display module 18 may have other structures, and this application is not particularly limited thereto.

[0068] In summary, the power supply system 1 provided in this application converts a first AC voltage from the power grid (e.g., 96-264V) to a first DC voltage and transmits it by installing a first conversion module 11, then, based on user needs, converts the first DC voltage (e.g., 48V) to a second DC voltage using a first power supply module 12, and converts the first DC voltage to a second AC voltage using a second power supply module 13. This reduces the energy consumption of the power supply system 1 and improves the safety of the power supply system 1 by making all user-accessible areas low-voltage DC voltage.

[0069] Furthermore, the first conversion module 11, the second conversion module 122, and the third conversion module 132 are all detachable and replaceable modules. If a malfunction occurs in the first conversion module 11, the second conversion module 122, or the third conversion module 132 in the power supply system 1, the user can immediately replace the first conversion module 11, the second conversion module 122, or the third conversion module 132, thereby reducing the difficulty of maintaining the power supply system 1 and improving the user experience with the power supply system 1.

[0070] Here, the power supply system 1 provided in this application is applicable to an office area, and the first power supply module 12 and the second power supply module 13 are installed on the corresponding office desks. Here, the office area may include a first office desk, a second office desk, and a third office desk. If the user of the first office desk works using a first external device, the first power supply module 12 may be installed only on the first office desk; if the user of the second office desk works using a second external device, the second power supply module 13 may be installed only on the second office desk; and if the user of the third office desk works using both the first and second external devices, both the first power supply module 12 and the second power supply module 13 may be installed on the third office desk.

[0071] Here, the third office desk can be equipped with two mounting positions to which the first power module 12 and the second power module 13 can be mounted, and similarly, both the first and second office desks can be equipped with two mounting positions. This allows the first power module 12 to be mounted in one mounting position on the first office desk while the other mounting position is left empty, and similarly, the second power module 13 to be mounted in one mounting position on the second office desk while the other mounting position is left empty. If a user of the first office desk needs to operate the second external device, the second power module 13 can be mounted in the empty mounting position to supply power to the second external device, and if a user of the second office desk needs to operate the first external device, the first power module 12 can be mounted in the empty mounting position to supply power to the first external device.

[0072] Alternatively, the first power module 12 can be mounted at either of the two mounting locations on the first office desk, thereby providing multiple power interfaces to the first external device. Similarly, the second power module 13 can be mounted at either of the two mounting locations on the second office desk, thereby providing multiple power interfaces to the second external device.

[0073] The first conversion module 11 first converts AC power from the power grid to DC power for transmission, thereby ensuring that all areas in contact with the user are at a low DC voltage, improving user safety. Furthermore, the second power module 13 is installed only at the office desk where the user needs to operate the second external device, thereby reducing the number of high-voltage AC power output ports in the office area and further improving user safety regarding the power system 1.

[0074] At the same time, the detachable and interchangeable arrangement of the first power module 12 and the second power module 13 in the office area meets the power supply needs of users for various external devices, improves the practicality of the power system 1 in the office area, and enhances the user experience of the power system 1.

[0075] This application also provides an office integrated power supply unit A, which, referring to Figure 6, is a schematic diagram of the structure of one embodiment of the office integrated power supply unit A of this application. The office integrated power supply unit A provided in this embodiment comprises at least one office desk and the power supply system 1, wherein the first power module 12 and the second power module 13 of the power supply system 1 are located on the corresponding office desk and are used to supply power to external devices installed on the office desk.

[0076] Specifically, only one first power module 12 can be installed at each office desk, and the second power module 13 can be installed only at office desks that have external devices requiring AC power supply. This reduces the number of AC power output terminals and improves user safety.

[0077] Alternatively, by equipping each office desk with both the first power module 12 and the second power module 13, the power needs of various external devices at the office desk can be met, improving the user experience of the office integrated power supply unit A.

[0078] Selectively, the office integrated power supply unit A further comprises at least one housing 2, the housing 2 having a housing cavity, and each housing is placed on a corresponding office desk, the housing cavity being used to house a first power module 12 and a second power module 13, thereby separating the first power module 12 and the second power module 13, improving the aesthetics of the office desk, and further enhancing the user experience of the office integrated power supply unit A.

[0079] Here, the connection module 15 and the first conversion module 11 in the power supply system 1 can be installed on the wall of the office area and connected via wiring to the first power module 12 and the second power module 13 located in the housing 2 on the office desk. A fixing plate for securing the housing 2 may also be provided on the desktop of the office desk.
