Description

Technical Field

[0001] This invention relates to the field of power supply technology for electronic devices, specifically to a multi-channel DC power supply system and a power output hub. Background Technology

[0002] In fields such as electronic equipment repair, laboratory testing, and development, DC regulated power supplies are indispensable tools. Currently, the mainstream products on the market are mostly integrated desktop linear power supplies or switching power supplies. These devices typically integrate one or more AC-DC conversion modules, DC-DC control circuits, voltage / current regulation units, display modules, and multiple output interfaces (such as banana plugs and USB ports) all into a metal or plastic chassis.

[0003] While this traditional integrated structure is fully functional, it has gradually revealed a series of inherent defects in practical use: 1. Large space occupation. The entire power supply equipment must be placed on the workbench, and its huge size seriously encroaches on the operating space that could be used to place maintenance equipment, tools and testing instruments, resulting in a cluttered workbench.

[0004] 2. Poor portability. Due to its high integration and the presence of a heavy transformer and heat sink, the integrated power supply is heavy and bulky, making it difficult to move and inconvenient for technicians to carry when working at different workstations or in the field.

[0005] 3. Disorganized cable management. The equipment's input power cord and multiple output cables are all drawn from different locations within the same chassis, becoming tangled together. This further exacerbates the clutter on the work surface and poses safety hazards such as tripping over or pulling on the equipment.

[0006] 4. Concentrated heat dissipation and interference. The AC-DC conversion (which generates a lot of heat) and the precision DC-DC control circuit are placed in the same enclosed space. The heat accumulation can easily lead to accelerated aging of components. At the same time, power frequency interference may also have a negative impact on sensitive DC-DC circuits.

[0007] Therefore, how to simultaneously solve the aforementioned defects such as large space occupation, poor portability, chaotic cable management, and concentrated heat dissipation and interference has become an urgent technical problem to be solved. Summary of the Invention

[0008] Based on the above situation, the main objective of this invention is to provide a multi-channel DC power supply system and a power output hub to simultaneously solve the defects such as large space occupation, poor portability, chaotic cable management, and concentrated heat dissipation and interference.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, embodiments of the present invention disclose a multi-channel DC power supply system, comprising: The DC-DC converter module is equipped with a first power input interface and a first power output interface; The power output hub module is provided with a second power input interface and at least two DC output units. The second power input interface is electrically connected to the first power output interface of the DC-DC conversion module via a cable. Each DC output unit includes an output interface and a control switch electrically connected to the output interface. The control switch is used to independently control the power on / off of the corresponding output interface. Optionally, the DC-DC converter module is provided with fasteners for securing it to a vertical or horizontal surface. Optionally, the fastener is provided with a plug hole for detachable installation of the DC-DC converter module. Optionally, the DC-DC converter module is equipped with several buttons for adjusting operating parameters. Optionally, the DC-DC converter module is equipped with a display screen for displaying the operating status, with the display screen and several buttons arranged vertically. Optionally, the first power input interface is a Type-C interface and / or a round-head DC socket. Optionally, the control switch is a push-button switch with a status indicator light, which is configured to illuminate when the circuit is connected and de-illuminate when the circuit is disconnected. Optionally, the housing of the power output hub module has an obtuse triangular or trapezoidal cross-section, which forms an inclined operation panel when placed on a horizontal plane, and the control switch and output interface are located on the inclined operation panel. Optionally, there may be multiple DC output units arranged in a row, with output interfaces being USB and / or Type-C interfaces. Secondly, embodiments of the present invention disclose a power output hub, comprising: a second power input interface and at least two DC output units; The second power input interface is electrically connected to an external DC power supply via a cable. Each DC output unit includes an output interface and a control switch electrically connected to the output interface. The control switch is used to independently control the power on / off of the corresponding output interface. Beneficial effects

[0010] The multi-channel DC power supply system and power output hub provided in this invention, due to the adoption of a separate technical solution including a DC-DC conversion module and a power output hub module, have at least the following advantages compared to traditional integrated power supplies: 1. Significantly reduces work surface area occupied, optimizing workspace. By physically separating the DC-DC conversion module from the power output hub module, and with the DC-DC conversion module connecting to the power supply via the first power input interface (eliminating the need for AC-DC conversion), it becomes more portable. The DC-DC conversion module can be fastened to vertical or horizontal surfaces outside the work area, such as behind the monitor, on a wall, or on a desk leg, thus removing the heaviest and largest component of the power supply system from the work surface. Only the compact and lightweight power output hub module needs to be placed on the desktop, significantly freeing up valuable desktop space, making the work surface cleaner, more spacious, and easier for maintenance and testing.

[0011] 2. Effectively improves system portability and ease of use. As a standalone, lightweight terminal, the power output hub module can be connected to a fixed DC-DC converter module via cable or to other external DC power supplies. When users need to work remotely or in the field, they can carry only this hub module and power it with a general-purpose DC power supply, achieving a flexible configuration mode of multi-purpose use and mobile terminal, completely solving the problem of bulky and difficult-to-carry traditional integrated power supplies.

[0012] 3. Cable management was optimized, eliminating potential safety hazards. All power cables for the devices are routed from a hub module on the desktop, avoiding the tangled and messy problems caused by multiple cables running from the same device. The more organized desktop cables are not only aesthetically pleasing but also reduce the safety risks of tripping over or pulling on devices due to cables.

[0013] 4. Improve system heat dissipation and anti-interference performance, and enhance reliability. By separating the heat-generating DC-DC converter circuit and the terminal output circuit into two separate modules, the DC-DC converter module can be installed in a better-ventilated open space, fundamentally improving heat dissipation and helping to reduce the operating temperature of components and extend their service life. At the same time, physical isolation also reduces the impact of power frequency interference that may be generated during AC-DC conversion on the precision DC-DC control circuit, improving the stability and accuracy of the output voltage.

[0014] In addition, each DC output unit is equipped with an independent control switch, allowing users to independently manage the power supply and shutdown of devices connected to different output interfaces without frequently plugging and unplugging device cables. This design is not only intuitive and convenient to operate, but also avoids interface damage that may occur during plugging and unplugging, enhancing safety and extending device lifespan.

[0015] It is evident that the multi-channel DC power supply system and power output hub disclosed in this application simultaneously solve the aforementioned defects such as large space occupation, poor portability, chaotic cable management, and concentrated heat dissipation and interference.

[0016] Other beneficial effects of the present invention will be explained in detail through the introduction of specific technical features and technical solutions in specific embodiments. Those skilled in the art should be able to understand the beneficial technical effects brought about by these technical features and technical solutions through the introduction of these technical features and technical solutions.

Detailed Implementation

[0018] The present invention is described below based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail, but well-known methods, processes, procedures, and elements are not described in detail in order to avoid obscuring the essence of the present invention.

[0019] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0020] Unless the context explicitly requires it, the words "comprising," "including," and similar terms throughout the specification and claims should be interpreted as encompassing rather than being exclusive or exhaustive; that is, meaning "including but not limited to."

[0021] In the description of this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0022] To simultaneously address the aforementioned drawbacks such as large space occupation, poor portability, chaotic cable management, and concentrated heat dissipation and interference, this invention discloses a multi-channel DC power supply system. Please refer to [link / reference]. Figure 1 and Figure 2 , Figure 1This is a front view diagram of a DC-DC conversion module disclosed in this embodiment. Figure 2 This is a schematic diagram of a power output hub module disclosed in this embodiment. The multi-channel DC power supply system includes a DC-DC conversion module 100 and a power output hub module 200. These two modules are physically independent and are electrically connected only through a cable, working together to complete the power supply function. Details are as follows: Please refer to Figure 1 The DC-DC converter module 100 is the core of the power processing in this system. Its housing houses a DC-DC conversion circuit (not shown in the figure). The housing has a first power input interface 101 for receiving DC power from an external power source. The housing also has a first power output interface 102, which is electrically connected to the output of the internal DC-DC conversion circuit and outputs converted and regulated DC power. In practice, the first power output interface 102 is preferably a banana plug socket; however, a USB or Type-C interface can also be configured.

[0023] Please refer to Figure 1 The first power input interface 101 is specifically in the form of a Type-C interface and / or a round-head DC socket. This improves the compatibility of the input power supply, allowing users to use either common AC-DC adapters with round-head DC output plugs or adapters using the modern USB PD protocol (via a Type-C interface) to power it.

[0024] Please refer to Figure 2 The power output hub module 200 is the desktop-level multi-output terminal of this system. The power output hub module 200 is equipped with a second power input interface 201 and at least two DC output units 202. The second power input interface 201 is electrically connected to the first power output interface 102 of the DC-DC conversion module 100 via a cable. Specifically, the second power input interface 201 is provided on the housing of the power output hub module 200. This second power input interface 201 is electrically connected to the first power output interface 102 of the DC-DC conversion module 100 via a cable (not shown in the figure), thereby receiving DC power processed by the DC-DC conversion module 100.

[0025] Please refer to Figure 2The power output hub module 200 also has at least two DC output units 202 on its housing. Each DC output unit 202 is an independent functional unit, including an output interface 202a and a control switch 202b. The control switch 202b is used to independently control the power supply to the corresponding output interface. In this embodiment, the output interface 202a is used to connect to external electrical equipment (such as a circuit board under test, development board, etc.). The control switch 202b is electrically connected to the output interface 202a and is configured to be user-operable to independently control the circuit's open and closed states of the corresponding output interface 202a. Thus, the user can turn the power supply to the corresponding interface on or off by operating a control switch 202b without affecting the operation of other output units 202.

[0026] In practice, an external DC power source (such as an AC-DC adapter) is connected to the first power input interface 101 of the DC-DC conversion module 100. After internal circuit conversion and voltage regulation, the power is output from the first power output interface 102. This power is transmitted to the second power input interface 201 of the power output hub module 200 via a connecting cable. The hub module internally distributes the power to each DC output unit 202. The user can independently control the power supply of the device connected to each output interface 202a by operating the control switch 202b on each unit.

[0027] To install the DC-DC converter module 100, please refer to... Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the back structure of a DC-DC conversion module disclosed in this embodiment. Figure 4 This is an exploded view of the rear structure of a DC-DC converter module disclosed in this embodiment. In an optional embodiment, the DC-DC converter module 100 is provided with fasteners 103 for fixing it to a vertical or horizontal surface. Figure 3 and Figure 4 As shown, a fastener 103 is further provided on the back or side of the housing of the DC-DC converter module 100. The fastener 103 can be a separate component (such as a mounting ear with holes) or part of the housing (such as a raised platform). Thus, the entire DC-DC converter module 100 can be mounted on a vertical surface (such as a wall or monitor bracket) or a horizontal surface (such as under a desk), thereby achieving concealed installation of the module.

[0028] Furthermore, a plug-in hole 103a is provided on the fastener 103. By passing screws or other fasteners through the plug-in hole 103a, the entire DC-DC converter module 100 can be detachably and securely installed, thereby improving the convenience of detachable installation.

[0029] To facilitate human-computer interaction, please refer to Figure 1 In an optional embodiment, the DC-DC conversion module 100 is provided with several buttons 104 for adjusting operating parameters. These buttons 104 are used to adjust system operating parameters, such as output voltage value, output current limit value, etc. In addition, a display screen 105 is provided to display the system's operating status in real time, such as the current output voltage, output current, etc. Figure 1 As shown, the display screen 105 and several buttons 104 are arranged vertically, with the display screen 105 at the top for easy observation and the buttons 104 at the bottom for easy operation, which is a reasonable layout.

[0030] In a preferred embodiment, please refer to Figure 2 The control switch 202b is a push-button switch with a status indicator light. It is configured so that the indicator light illuminates when the circuit is connected and turns off when the circuit is disconnected. The internal circuitry of the control switch 202b on the power output hub module 200 is configured such that when the switch is pressed, connecting the circuit of the output interface 202a it controls, its built-in indicator light (such as an LED) illuminates simultaneously; when pressed again, disconnecting the circuit, the indicator light turns off. This provides the user with a clear and intuitive status indication.

[0031] To enhance the stability of the power output hub module 200, in an optional embodiment, please refer to... Figure 2 The power output hub module 200 has an obtuse-angled triangular or trapezoidal cross-section, forming an inclined operation panel when placed on a horizontal surface. The control switch 202b and output interface 202a are located on this inclined operation panel. In this embodiment, the term "obtuse-angled triangle or trapezoid" refers to a shape with an approximate obtuse-angled triangle or trapezoidal outline, on which appropriate mechanical reinforcements such as chamfers or protrusions can be fabricated. When the power output hub module 200 is placed on a horizontal platform, its top surface naturally forms a rearward-inclined operation panel. The control switch 202b and output interface 202a are both located on this inclined operation panel, thus conforming to ergonomic design, ensuring that the interface and switch face the user for easy viewing and operation.

[0032] In this embodiment, the obtuse-angled triangle or trapezoidal structure forms a stable shape with a low center of gravity and a base that is wider at the back and narrower at the front. When the user operates the buttons on the front panel, the downward pressure will make it fit more snugly against the tabletop. When the power input cable at the rear is accidentally pulled, the structure can effectively resist the rotational torque with the bottom front edge as the fulcrum, reducing the risk of the device tipping backward.

[0033] In an optional embodiment, the number of DC output units 202 is multiple and arranged in a line, with output interfaces being USB and / or Type-C interfaces. Please refer to... Figure 2 and Figure 5 , Figure 5 This is a schematic diagram of another structure of a power output hub module disclosed in this embodiment. Figure 2 This indicates that the output interface 202a is a USB interface (such as USB-A). Figure 5 The diagram shows that the output interface 202a is a Type-C interface. Of course, in actual implementation, these two types of interfaces can be combined to adapt to the charging and data cable needs of different devices.

[0034] This embodiment also discloses a power output hub; please refer to [reference needed]. Figure 2 and Figure 5 The power output hub includes a second power input interface 201 and at least two DC output units 202. The second power input interface 201 is electrically connected to an external DC power supply via a cable. Each DC output unit 202 includes an output interface 202a and a control switch 202b electrically connected to the output interface 202a. The control switch 202b is used to independently control the power on / off of the corresponding output interface. In other words, the power output hub module 200 disclosed in the above embodiment is considered a standalone product. In specific applications, the external DC power supply can be the DC-DC conversion module 100 of this invention, or any other power supply device capable of providing suitable DC power. The structure and function of each DC output unit 202 are exactly the same as described above, possessing an output interface 202a and an independent control switch 202b. Therefore, the hub disclosed in this embodiment exhibits good modularity and versatility.

[0035] The multi-channel DC power supply system and power output hub provided in this invention, due to the adoption of a separate technical solution including a DC-DC conversion module and a power output hub module, have at least the following advantages compared to traditional integrated power supplies: 1.

Only the compact and lightweight power output hub module needs to be placed on the desktop, significantly freeing up valuable desktop space, making the work surface cleaner, more spacious, and easier for maintenance and testing.
