DETAILED DESCRIPTION

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application as claimed, but merely represents selected embodiments of the present application. It should be noted that, unless there is a conflict, the various features of the embodiments of the present application may be combined with each other, and the combined embodiments are still within the scope of protection of the present application.

[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0029] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended only to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0031] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0032] In one aspect of the embodiments of the present application, a modular control unit is provided, which can be applied to a charging pile, such as Figures 1 to 7 As shown, the modular control unit includes a power supply 10, a circuit board 20, a high-voltage output unit, a first shell 30 and a second shell 40. The power supply 10 is electrically connected to the high-voltage output unit via the circuit board 20. The first shell 30 and the second shell 40 are stacked along a first direction. The first shell 30 has a first accommodating cavity 30a, and the second shell 40 has a second accommodating cavity 40a. The high-voltage output unit is placed in the first accommodating cavity 30a, and the power supply 10 and the circuit board 20 are placed in the second accommodating cavity 40a. The first accommodating cavity 30a has a first opening, and the second shell 40 covers the periphery of the first opening.

[0033] Specifically, by electrically connecting the power supply 10 to the high-voltage output unit via the circuit board 20, efficient and stable signal transmission and current supply between the various components are ensured. The first housing 30 and the second housing 40 are stacked along a first direction. This design not only saves space but also optimizes component layout. The first direction refers to the height of the charging station. The first housing 30 has a first accommodating chamber 30a for accommodating the high-voltage output unit; the second housing 40 has a second accommodating chamber 40a for accommodating the power supply 10 and the circuit board 20. This layout effectively consolidates scattered components, isolates devices with different functions, and prevents mutual interference, significantly improving the stability of the electrical system. The first accommodating chamber 30a has a first opening to facilitate access and maintenance of the high-voltage output unit. The second housing 40 covers the periphery of the first opening, forming a closed structure that further enhances the system's dust and moisture resistance. This sealed design not only protects the internal electronic components from external environmental influences but also extends the lifespan of the modular control unit and reduces failure rates.

[0034] In summary, this modular control unit's stacked design significantly reduces the complexity of inter-component connections, making the assembly process more efficient. Furthermore, the modular structure simplifies subsequent maintenance and replacement, allowing operators to quickly repair or replace specific modules, effectively improving the system's adaptability and flexibility.

[0035] Optionally, the high-voltage output unit includes a contactor, a shunt, and a fuse, which complement each other to ensure stable power transmission and safe protection. As a core component of the high-voltage output unit, the contactor's primary function is to control the on / off flow of current. The contactor's structural design allows for safe operation under high current conditions. Through electromagnetic actuation, the contactor can rapidly switch states, achieving precise control of the power supply 10.

[0036] The shunt is responsible for distributing the input current to the various output terminals, ensuring that each module receives the appropriate amount of power. Its design typically includes multiple output channels to accommodate devices with different power requirements. By properly distributing current, the shunt improves the overall performance of the charging station, ensuring that all connected devices operate at optimal conditions.

[0037] Fuses play a crucial protective role in high-voltage output units. When the current exceeds a set threshold, the fuse quickly disconnects the circuit, preventing equipment damage or fire. Fuse material selection and design must consider response time and load capacity to ensure reliable operation under a wide range of operating conditions. Furthermore, fuses should be installed in a location that allows for easy access for inspection and replacement, enhancing overall system maintenance.

[0038] Optionally, insulating bakelite is placed within the first housing 30 for insulation. By properly arranging the insulating bakelite within the first housing 30, the power supply 10 can be effectively isolated from other metal structures, reducing the risk of equipment failure and ensuring safety during use. The thickness and shape of the insulating bakelite should be optimized based on the layout of the various components within the housing to maximize its insulating effect. Through scientific design, each insulating area can be ensured to meet safety standards and avoid any potential safety hazards. Furthermore, the insulating bakelite should have good mechanical strength to protect internal components from external shock and vibration to a certain extent.

[0039] Alternatively, as Figure 2 As shown, the second shell 40 includes a bottom plate, a first side plate 41, a second side plate 42, a third side plate 43, a fourth side plate 44 and a top plate, which are sequentially enclosed to form a second accommodating cavity 40a. The bottom plate has a second opening, and the first accommodating cavity 30a is connected to the second accommodating cavity 40a through the first opening and the second opening.

[0040] Specifically, by connecting the first and second openings of the first accommodating chamber 30a, a relatively independent yet interconnected space is formed. This design allows the power supply 10 and circuit board 20 to be freely arranged within the second accommodating chamber 40a, while also facilitating the installation and maintenance of the high-voltage output unit within the first accommodating chamber 30a. This channel design reduces signal transmission delays and ensures efficient communication between the power supply 10 and the high-voltage output unit.

[0041] Alternatively, as Figure 3 and Figure 4 As shown, a fifth side plate 45 parallel to the second side plate 42 is provided in the second shell 40, and both ends of the fifth side plate 45 are respectively connected to the first side plate 41 and the third side plate 43, and a slide rail 46 extending along a second direction perpendicular to the first direction is respectively provided on the second side plate 42 and the fifth side plate 45, and the first side plate 41 and / or the third side plate 43 has a third opening, and the circuit board 20 is slidably installed on the slide rail 46 through the third opening.

[0042] Specifically, to enable flexible component installation and access, a fifth side panel 45 parallel to the second side panel 42 is provided between the second side panel 42 and the fourth side panel 44. Both ends of the fifth side panel 45 are reliably connected to the first side panel 41 and the third side panel 43. Slide rails 46 extending in a second direction perpendicular to the first direction are provided on the second side panel 42 and the fifth side panel 45, respectively. This design allows the circuit board 20 to be installed by sliding, forming a drawer-like structure, so that the circuit board 20 can be easily pulled out from the third opening of the first side panel 41 and / or the third side panel 43. This design not only improves the accessibility of the circuit board 20, but also simplifies the maintenance and replacement process, allowing operators to easily operate without having to disassemble the entire second housing 40.

[0043] Furthermore, two circuit boards 20 can be positioned within the second accommodating cavity 40a along the second direction, allowing one circuit board 20 to be drawn through the third opening on the first side panel 41, while the other circuit board 20 can be drawn through the third opening on the third side panel 43. This bidirectional drawer design prevents the two circuit boards 20 from interfering with each other during placement and removal, significantly enhancing the system's flexibility and ease of operation. To prevent interference between the circuit boards 20 due to excessive sliding, a stopper should be installed in the middle of the slide rail 46. This not only ensures the stability of the circuit boards 20 but also protects the safety of the electronic components.

[0044] In general, by sliding and pulling, the operator can conveniently operate the circuit board 20, making the installation and removal of the circuit board 20 more efficient, thereby improving the convenience of maintenance and the overall system reliability.

[0045] Alternatively, as Figure 3 and Figure 4 As shown, a panel 50 is fixedly connected to the end of the circuit board 20. The design of the panel 50 not only enhances the operability of the circuit board 20, but also provides additional support for the fixation of the circuit board 20. The panel 50 is firmly connected to the circuit board 20 via a fixed connector 51, allowing the operator to easily drive the circuit board 20 to slide through the panel 50. The size of the panel 50 matches the third opening, so that after the circuit board 20 is slidably placed in the second accommodating cavity 40a, the panel 50 can be embedded in the third opening, forming a neat and stable connection, and the third opening is sealed, ensuring the safety of the circuit board 20 during use and preventing component damage due to improper operation.

[0046] It should be understood that the circuit board 20 can also be fixed to the panel 50 using screws 52. The screw heads 52 are located outside the second housing 40. This not only makes it easier for operators to install and remove the circuit board 20, but the screws 52 themselves can also serve as operating handles, making the process of pulling out the circuit board 20 smoother. This dual-function design can enhance the user experience and simplify the maintenance process.

[0047] Optionally, a plurality of circuit boards 20 are stacked along the first direction in the second accommodating cavity 40a, a plurality of slide rails 46 are respectively provided on the second side panel 42 and the fifth side panel 45, the first side panel 41 and / or the third side panel 43 have corresponding plurality of third openings, and each circuit board 20 is slidably installed on the corresponding slide rail 46 through the corresponding third opening.

[0048] Specifically, by stacking multiple circuit boards 20 along the first direction within the second accommodating cavity 40a, space utilization can be optimized, making the internal structure of the charging pile more compact and efficient. To ensure smooth sliding and placement of the circuit boards 20, multiple slide rails 46 are provided on the second side panel 42 and the fifth side panel 45, respectively. These slide rails 46 provide a stable sliding path for the circuit boards 20, and each circuit board 20 can slide independently on the slide rails 46, facilitating maintenance and replacement.

[0049] Corresponding third openings are provided on the first side panel 41 and / or the third side panel 43, allowing each circuit board 20 to be slidably mounted on a corresponding slide rail 46 through its respective third opening. This design allows the circuit boards 20 to be arranged in an orderly manner within the second accommodating cavity 40a, ensuring a neat and aesthetically pleasing appearance while greatly facilitating user convenience. Multiple circuit boards 20 can be independently removed and placed without interfering with each other, thereby enhancing the flexibility and convenience of the system.

[0050] Based on the above, it can be seen that by stacking along the first direction in the second accommodating cavity 40a, multiple circuit boards 20 can be arranged in an array in parallel along the second direction, which effectively improves the operability and neatness of the circuit boards 20 and can meet the needs of different application scenarios.

[0051] Alternatively, as Figure 5 and Figure 6 As shown, positioning posts 47 are provided on the first side plate 41 , the second side plate 42 and / or the third side plate 43 , and positioning grooves 31 cooperating with the positioning posts 47 are provided on the side plates of the first housing 30 .

[0052] Specifically, to ensure alignment between the second housing 40 and the first housing 30, multiple positioning posts 47 are provided on the first side panel 41, the second side panel 42, and / or the third side panel 43. Positioning slots 31 are designed on the side panels of the first housing 30 to mate with the positioning posts 47. This ensures accurate alignment of the components during assembly, avoiding structural instability or functional impairments caused by positional deviations. Furthermore, during assembly, the operator simply inserts the positioning posts 47 into the corresponding positioning slots 31 to quickly and accurately complete the docking of the two. This structural connection method not only simplifies the assembly process, but also improves assembly efficiency and reduces installation errors caused by human factors.

[0053] Alternatively, as Figure 7 As shown, the power supply 10 is installed on the inner side of the fourth side panel 44, and a first folded edge 441 is provided at one end of the fourth side panel 44 close to the first shell 30. A guide rail 32 extending along the second direction is provided on the side panel of the first shell 30 corresponding to the fourth side panel 44, and the first folded edge 441 is slidably installed on the guide rail 32.

[0054] Specifically, the power supply 10 is fixedly mounted on the inner side of the fourth side panel 44. This layout effectively utilizes space and ensures the stability of the power supply 10. To enhance the maintainability of the power supply 10, a first folded edge 441 is provided at the end of the fourth side panel 44 near the first housing 30. The side panel of the first housing 30 corresponding to the fourth side panel 44 is designed with a guide rail 32 extending along the second direction. This ensures convenient installation and removal of the power supply 10, forming an efficient drawer-type structure.

[0055] By sliding the first folded edge 441 onto the guide rail 32, the fourth side plate 44 easily drives the power supply 10 along the guide rail 32, making it extremely easy to remove and place the power supply 10. The operator simply pulls the fourth side plate 44, and the power supply 10 slides in and out along the guide rail 32, enabling quick installation and removal. This significantly reduces the time and effort required by traditional fixed installation methods and improves work efficiency.

[0056] It should be noted that the material of the guide rail 32 should be wear-resistant and corrosion-resistant to ensure good sliding performance even after long-term use. At the same time, the gap between the folded edge and the guide rail 32 should be reasonably considered during the design to ensure smooth sliding without excessive looseness that affects overall stability.

[0057] It should also be noted that the guide rail 32 can be formed by bending the side panels of the first housing 30. This integrated design simplifies the structure, allowing the guide rail 32 to be tightly integrated with the first housing 30, enhancing overall stability and structural integrity, and improving material utilization efficiency during the manufacturing process. Furthermore, the design of the bent guide rail 32 reduces the number of connectors, reducing potential points of failure, and thus improving device reliability.

[0058] Alternatively, as Figure 6 and Figure 7 As shown, a second folded edge 442 is provided at one end of the fourth side plate 44 close to the first side plate 41 , and the first folded edge 441 slides along the guide rail 32 toward the direction close to the first side plate 41 so that the second folded edge 442 abuts against the first side plate 41 .

[0059] Specifically, by providing a second folded edge 442 at the end of the fourth side panel 44 near the first side panel 41, the positioning and stability of the power supply 10 can be effectively improved. The first folded edge 441 slides along the guide rail 32, moving toward the first side panel 41, ensuring that the second folded edge 442 can contact the first side panel 41. This structural connection ensures that the fourth side panel 44 can be accurately positioned during use of the power supply 10, thus avoiding unnecessary displacement.

[0060] The provision of the second folded edge 442 not only positions the second side panel 42 along the second direction but also ensures that the fourth side panel 44 has a certain limit effect during the sliding process. When the fourth side panel 44 slides along the guide rail 32 until the second folded edge 442 abuts the first side panel 41, the design of the second folded edge 442 prevents the fourth side panel 44 from sliding further, ensuring that its position remains unchanged during operation of the power supply 10, avoiding potential damage due to excessive sliding, and extending the service life of the power supply 10.

[0061] It should be noted that the shape and size of the second folded edge 442 should be properly considered during application to ensure sufficient contact area between it and the first side plate 41 to achieve a good positioning effect. In addition, the material selection should focus on wear resistance and corrosion resistance to ensure reliability in long-term use.

[0062] Alternatively, as Figure 7As shown, for the convenience of connecting the fourth side plate 44 to the third side plate 43, the fourth side plate 44 can be designed as an L-shaped structure. The L-shaped structure includes a bent portion through which the connection with the third side plate 43 can be achieved. Thus, during use, one end of the fourth side plate 44 abuts against the first side plate 41, and the other end of the fourth side plate 44 is connected to the third side plate 43 through the bent portion, enabling the stability and flexibility of the structure.

[0063] Optionally, as Figure 6 shown, ventilation openings 33 are provided on the side plates of the first housing 30, first mounting holes 34 are provided on the side plates of the first housing 30, the first mounting holes 34 are used for mounting distribution copper bars, and / or second mounting holes 35 are provided on the side plates of the first housing 30, and the second mounting holes 35 are used for mounting electric meters.

[0064] Specifically, multiple functional channels are provided on the side plates of the first housing 30. The design of these channels can not only optimize the utilization of the internal space but also improve the overall performance and user experience of the device. First, the ventilation openings 33 located on the side plate of the first housing 30 along the second direction are used for installing cooling fans to enhance the air circulation inside the housing and ensure that the power supply 10 and other electronic components maintain an appropriate temperature during operation. This design utilizes the principle of air convection to effectively prevent overheating, thereby improving the operating efficiency and service life of the device.

[0065] In addition, first mounting holes 34 are also provided on the side plate of the first housing 30 perpendicular to the second direction, specifically for mounting distribution copper bars. The mounting holes are designed in a "soil" shape, enabling the distribution copper bars to be firmly fixed when entering and exiting. This design can not only ensure the connection of the distribution copper bars to external devices but also provide a good power distribution and connection solution for internal components. By integrating the design of the distribution copper bars into the housing structure, the complexity of wiring is reduced, thereby enhancing the overall aesthetics and maintainability of the device.

[0066] To further enhance the functionality of the device, second mounting holes 35 are also provided on the side plate of the first housing 30 along the second direction, specifically for mounting electric meters. This design takes into account the user's need to monitor the power consumption of the device. By directly mounting the electric meter on the side plate, users can conveniently read and monitor the power consumption. The setting of the electric meter not only improves the practicality of the charging pile but also makes the operation of the device more user-friendly.

[0067] In terms of user operation, handles 36 for easy handling are also designed on the opposite side plates of the first housing 30. The setting of the handles 36 takes into account the convenience of users when installing and moving the first housing 30, enabling the first housing 30 to be easily carried and positioned by the operator. The design of the handles 36 can incorporate ergonomics to ensure the comfort and safety of users during handling, thereby improving the overall user experience.

[0068] Optionally, a third mounting hole is provided on the side panel of the second housing 40 , and the third mounting hole is used for mounting a wiring terminal.

[0069] Specifically, a third mounting hole is provided on the side panel of the second shell 40, which is specifically used for installing the terminal block, and is intended to provide convenience and flexibility for electrical connection. The position design of the third mounting hole has been carefully considered to ensure that it can be smoothly docked with the terminal block. By providing this hole on the side panel of the second shell 40, the exposure of the cable and external interference can be effectively reduced. Secondly, attention should also be paid to the coordination between the third mounting hole and the surrounding structure to ensure smooth and safe installation. In addition, in order to further protect the electrical performance of the terminal block, the area around the third mounting hole should be sealed to prevent the intrusion of external factors such as dust and moisture.

[0070] This design not only reduces the risk of potential failures caused by the external environment but also facilitates subsequent maintenance and replacement. Furthermore, it effectively prevents the terminals from loosening due to vibration or external forces, enhancing the stability and reliability of the entire system. The shape and size of the holes are precisely calculated to accommodate terminal blocks of varying sizes, ensuring consistency throughout each installation.

[0071] Furthermore, a third mounting hole can be provided on the panel 50, thereby optimizing the user's operating experience. Providing the hole directly on the panel 50 makes the terminal block installation and connection more intuitive. Operators can easily make and break electrical connections without affecting the extraction of the circuit board 20, reducing the difficulties caused by space constraints.

[0072] On the other hand, an embodiment of the present application provides a charging pile, comprising a cabinet and any one of the above-mentioned modular control units, wherein the modular control unit is arranged in the cabinet. The cabinet serves as the outer shell of the entire charging pile, which not only provides physical protection but also provides space for the reasonable arrangement and operation of internal components.
