Description

Technical Field

[0001] This application relates to the technical field of charging equipment, and in particular to a miniaturized charging pile based on internal structure optimization. Background Technology

[0002] In the field of charging pile technology, with the rapid development of electric vehicles, the demand for charging piles is also increasing. As an important infrastructure for the energy replenishment of electric vehicles, the development of charging pile technology is of great significance to the popularization and promotion of electric vehicles. Efficient, stable, and miniaturized charging piles can better adapt to different installation environments, improve space utilization, and provide users with more convenient charging services, playing a positive role in promoting the development of the electric vehicle industry. At the same time, with the increasing scarcity of urban space, miniaturized charging piles have become an important trend in industry development. In the past, to achieve the functions of charging piles, a relatively traditional layout was usually adopted in structural design. For the placement of electrical components, open or simple partitioned structures were often used, with various electrical components randomly placed in the cabinet without reasonable layering and layout planning. For heat dissipation, simple direct fan blowing or ordinary ventilation openings on the cabinet were often used, relying on natural convection for heat dissipation. For door lock design, screw fixing or simple snap-fit ​​structures were commonly used to connect and lock the door to the cabinet. These conventional methods can meet the basic functional requirements of charging piles to a certain extent. However, the traditional charging pile structural layout has many problems. Open or simply partitioned placement of electrical components makes it difficult to precisely control the safety distance between them, easily generating electromagnetic interference. It also occupies a significant amount of lateral space, hindering the miniaturization design of charging stations. Simple fan-driven cooling and ordinary vents fail to achieve efficient heat exchange, cannot adequately meet the cooling needs of the internal components, and can easily lead to overheating within the cabinet, affecting the lifespan and performance of the components. Screw-fixed and simple snap-lock door structures are cumbersome to install and disassemble, requiring considerable time and manpower, and are prone to loosening and damage over long-term use.

[0003] Therefore, in view of the above situation, there is an urgent need to develop a miniaturized charging pile based on internal structure optimization, so as to overcome the shortcomings in current practical applications. Summary of the Invention

[0004] To address the shortcomings of the aforementioned technologies, this application provides a miniaturized charging pile based on optimized internal structure.

[0005] This application provides a miniaturized charging pile based on internal structure optimization, which adopts the following technical solution: A miniaturized charging pile based on internal structure optimization includes a cabinet, which is equipped with a switch door and a locking module for locking the switch door and the cabinet. The cabinet is equipped with a placement module for placing electrical appliances and a cooling module for cooling the environment inside the cabinet.

[0006] Beneficial Effects: By integrating the cabinet, door, and modules that combine locking, placement, and cooling functions into a single design, the equipment achieves miniaturization and optimized internal structure. The door provides access for maintenance, the locking module ensures secure closure, the placement module rationally plans the internal electrical layout, and the cooling module actively manages the cabinet temperature. This lays the foundation for the overall miniaturization and structural optimization of the equipment. Modular division (locking, placement, and cooling) makes the internal structure clear and compact, reducing redundant space and effectively reducing the overall size of the charging pile while ensuring full functionality, facilitating installation and deployment. Furthermore, the modular design, with each component fulfilling its specific function, also facilitates future maintenance and upgrades.

[0007] In one optional embodiment, the locking module includes a locking box. A fixing post is provided on the inner side of the switch door, and the locking box is inserted into the fixing post. A rotating gear is rotatably arranged inside the locking box. A rotating block is provided at one end of the rotating gear, and a rotating sleeve is provided at the other end of the rotating gear. The rotating sleeve extends out of the locking box, and a rotating handle is fixedly arranged outside the rotating sleeve. A limit groove is formed inside the locking box. An upper locking rod and a lower locking rod are respectively inserted into the upper and lower sides of the locking box. The upper locking rod has multiple tooth grooves at one end of the locking box. The upper locking rod and the lower locking rod have the same structure. The rotating gear meshes with the tooth grooves on the upper locking rod and the lower locking rod for transmission.

[0008] Beneficial effects: The door and cabinet are locked by the meshing of rotating gears and upper and lower locking rods. The installation of the locking module is facilitated by the cooperation of the fixing column and locking box. Operation is simple; a single rotation controls both locking points, improving efficiency. The structure is compact and reliable, integrating the transmission mechanism into the locking box, minimizing space usage. The stable gear and rack transmission provides high mechanical strength, enhancing locking reliability and anti-theft capabilities. It also facilitates miniaturization; the integrated design reduces the overall size of the lock, aligning with the principle of internal structure optimization.

[0009] In one optional embodiment, an embedded groove is provided on the outer side of the switch door, and a rotating hole is provided in the embedded groove. The rotating hole is concentrically arranged with the rotating gear. A rotating ring is rotatably arranged in the rotating hole.

[0010] Beneficial effects: The installation of a door opening and closing mechanism and locking module on the cabinet enables the door to be locked to the cabinet. The locking module includes a locking box, rotating gears, and other components. Rotating the handle drives the rotating gears, which in turn moves the upper and lower locking rods to achieve the locking function. An embedded groove and a rotating hole are provided on the outside of the door. A rotating ring and a rotating handle are installed in the rotating hole. A rotating block is inserted into the square groove of the rotating ring. The rotating gears can be easily controlled by rotating the handle, thereby controlling the locking and opening of the door.

[0012] Beneficial effects: Inserting the upper and lower locking rods into their corresponding brackets securely locks the door to the rack, preventing accidental opening and improving the safety and stability of the charging station. The two-point plug-in locking system makes the connection between the door and the rack more stable, effectively resisting shaking and prying. The brackets provide clear guidance and target positions for the extension of the locking rods, ensuring that the locking mechanism is accurately aligned and locked every time the door is closed, improving reliability. As part of the rack structure, the brackets require no complex moving parts, are robust, and have a long lifespan.

[0013] In one optional embodiment, the cooling module includes a ventilation slot, which is provided on one side of the cabinet. A ventilation door is hinged within the ventilation slot, and an exhaust duct is provided within the ventilation door. An exhaust grille is provided within the exhaust duct. Multiple limiting covers are provided on the side of the ventilation door facing the inside of the cabinet, and multiple air passage holes are provided on the limiting covers. A fan is rotatably installed within each air passage hole. An isolation cover is provided over the limiting covers, and the isolation cover is located on the inner side of the cabinet. An isolation grid is provided on the side of the isolation cover facing the inside of the cabinet, and a platform grille is provided on the isolation cover. Ventilation holes are provided at the top and bottom of the isolation cover.

[0014] Beneficial effects: Forced ventilation by the fan greatly enhances airflow inside the cabinet, and its heat dissipation efficiency is far higher than that of natural convection, making it suitable for the working environment of heat-generating devices inside the charging pile; the design of the isolation cover and grille can prevent large dust particles and foreign objects from directly entering the electrical area while ensuring ventilation, and isolate personnel from internal moving parts such as fans, thus improving safety; the design of the ventilation door that can be opened makes it very easy to clean the fan and air duct, which is conducive to maintaining cooling efficiency in the long term.

[0015] In one optional embodiment, the placement module includes a fixing frame. The fixing frame is fixedly installed on the side of the cabinet away from the limiting cover.

A placement groove is opened in the middle of the platform grille, and a fixing box is inserted into the placement groove. The other end of the fixing box is fixedly connected to the middle of the fixing frame.

[0016] Beneficial effects: A ventilation slot and hinged ventilation door are opened on one side of the cabinet. An exhaust grille is installed inside the ventilation door. A fan-equipped limit cover is installed facing the ventilation door into the cabinet. An isolation cover with an isolation plate, a platform grille, and ventilation holes is installed outside the limit cover. This can cool the environment inside the cabinet. At the same time, the isolation cover can also play a certain role in isolation and protection. Through the layered (bearing plate) and partitioned (fixed box) layout, the three-dimensional space of the cabinet is fully utilized, which is a key internal structural optimization to achieve miniaturization. Electrical equipment can be installed in different planes and positions in a categorized manner, with clear wiring and no interference between them, which is conducive to heat dissipation and maintenance. One end of the bearing plate is fixed to the fixed frame, and the other end is connected to the platform grille. The fixed box is inserted and fixed, forming a stable and reliable bearing system, which can ensure that the equipment works stably in environments with vibration.

[0017] In one alternative embodiment, a limiting plate is provided on the side of the isolation cover and the fixing frame facing the switch door, and multiple mounting brackets are provided on the limiting plate.

[0018] Beneficial effects: The cabinet is equipped with placement modules, cooling modules, and locking modules, which can house electrical appliances, cool the internal environment of the cabinet, and lock the door. The placement module includes a fixing frame, a support plate, and a fixing box, which can house electrical appliances. The cooling module includes ventilation slots, ventilation doors, exhaust grilles, limit covers, fans, isolation covers, isolation grids, platform grilles, and ventilation holes, which can cool the internal environment of the cabinet. Limit plates are set on the side of the isolation cover and fixing frame facing the door, and multiple mounting brackets are set on the limit plates, which can be used to install other components and optimize the internal structural layout.

[0019] In one optional embodiment, the switch door is provided with an electronic control module, which is connected to the electrical components within the placement module via electrical signals.

[0020] Beneficial effect: By installing an electrical control module on the door that is connected to the electrical appliances inside the placement module via electrical signals, the electrical appliances inside the placement module can be controlled.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1.

This laid the foundation for the miniaturization and structural optimization of the entire device. Modular division (locking, placement, cooling) resulted in a clear and compact internal structure, reducing redundant space and effectively minimizing the overall size of the charging pile while ensuring full functionality, facilitating installation and deployment. Simultaneously, the modular design, with each component fulfilling its specific function, also facilitates later maintenance and upgrades. 3. Forced ventilation by the fan greatly enhances airflow inside the cabinet, with heat dissipation efficiency far exceeding that of natural convection, making it suitable for the working environment of heat-generating components inside the charging pile; the design of the isolation cover and grille can ensure ventilation while preventing large dust particles and foreign objects from directly entering the electrical area, and isolate personnel from internal moving parts such as fans, thus improving safety; the design of the ventilation door that can be opened makes cleaning the fan and air duct very easy, which is conducive to maintaining cooling efficiency in the long term.

[0028] The present invention provides the following embodiments: Example 1

[0029] like Figure 1 As shown in the figure, the miniaturized charging pile based on internal structure optimization provided in this application embodiment includes a cabinet 1, a switch door 2, a locking module 3, a placement module 4, a cooling module 5, and an electrical control module 6. The switch door 2 is mounted on the cabinet 1, the locking module 3 is mounted on the switch door 2 to lock the switch door 2 and the cabinet 1, the placement module 4 and the cooling module 5 are located inside the cabinet 1, and the electrical control module 6 is mounted on the switch door 2 and is electrically connected to the electrical components within the placement module 4. This structural layout allows all parts of the charging pile to work collaboratively, satisfying the charging function requirements while optimizing the internal structure through a reasonable layout, reducing electromagnetic interference, improving heat dissipation efficiency, and enhancing installation convenience.

[0030] Specifically, such as Figure 1 , Figure 4 , Figure 5 As shown, the locking module 3 includes a locking box 31. A fixing post 32 is provided on the inner side of the opening / closing door 2, and the locking box 31 is inserted into the fixing post 32. This insertion method facilitates installation and disassembly. A rotating gear 33 is rotatably mounted inside the locking box 31. One end of the rotating gear 33 has a rotating block 34, and the other end has a rotating sleeve 35. The rotating sleeve 35 extends outside the locking box 31, and a rotating handle 36 is fixedly mounted outside the rotating sleeve 35. The rotating gear 33 can rotate flexibly within the locking box 31, and the rotating handle 36 allows for manual operation of the rotating gear 33 by the operator. A limiting groove 311 is provided inside the locking box 31, which can limit the rotation of the rotating gear 33 and other components, ensuring their rotational stability. The upper locking rod 37 and lower locking rod 38 are respectively inserted into the upper and lower sides of the locking box 31. The upper locking rod 37, located at one end of the locking box 31, has multiple toothed grooves 371. The upper locking rod 37 and lower locking rod 38 have identical structures. The rotating gear 33 meshes with the toothed grooves 371 on the upper locking rod 37 and lower locking rod 38 for transmission. When the rotating handle 36 rotates, driving the rotating gear 33 to rotate, the meshing transmission of the toothed grooves 371 allows the upper locking rod 37 and lower locking rod 38 to perform relative extension and retraction movements, thereby achieving the locking and unlocking of the door 2 and the cabinet 1. The rotating gear 33 can be made of metal, such as stainless steel, to ensure its strength and wear resistance; it can also be made of high-strength plastic to reduce weight and cost. The rotating handle 36 can be designed in a shape that is easy to grip, such as round or oval, or it can have anti-slip textures on its surface to increase ease of operation.

[0031] like Figure 4As shown, an embedded groove 21 is provided on the outer side of the switch door 2, and a rotating hole 22 is provided in the embedded groove 21. The rotating hole 22 is concentrically arranged with the rotating gear 33, and a rotating ring 23 is rotatably installed in the rotating hole 22. A rotating handle 24 is fixedly installed on the side of the rotating ring 23 away from the locking box 31. A square groove 25 is provided on the side of the rotating ring 23 facing the locking box 31, and a rotating block 34 is inserted into the square groove 25. A rotating groove 26 is provided on the rotating ring 23, and the edge of the rotating hole 22 is inserted into the rotating groove 26. The operator rotates the rotating handle 24 to drive the rotating ring 23 to rotate. The rotating ring 23, through the cooperation of the square groove 25 and the rotating block 34, drives the rotating gear 33 to rotate. The rotating ring 23 and the rotating handle 24 can be made of plastic in one piece to reduce cost and weight; or they can be made of aluminum alloy to improve strength and corrosion resistance.

[0032] like Figure 1 , Figure 3 , Figure 4 As shown, the top and bottom of the switch slot on the cabinet 1, which houses the switch door 2, are respectively provided with inserts 11. The top insert 11 of the switch slot is used to insert the upper locking rod 37, and the bottom insert 11 of the switch slot is used to insert the lower locking rod 38. When the rotating gear 33 drives the upper locking rod 37 and the lower locking rod 38 to extend, the upper locking rod 37 inserts into the top insert 11, and the lower locking rod 38 inserts into the bottom insert 11, thus achieving a secure lock between the switch door 2 and the cabinet 1. The inserts 11 can be made of rubber to provide a certain cushioning effect and reduce the impact force during locking; or they can be made of metal to ensure their structural strength.

[0033] like Figure 2As shown, the cooling module 5 includes a ventilation slot 51. A ventilation slot 51 is provided on one side of the cabinet 1. A ventilation door 52 is hinged within the ventilation slot 51, and an exhaust slot 53 is provided within the ventilation door 52. An exhaust grille 54 is provided within the exhaust slot 53. The ventilation door 52 can rotate around the hinge, facilitating maintenance and cleaning of the ventilation slot 51. The exhaust grille 54 prevents debris from entering the ventilation slot 51 while ensuring air circulation. Multiple limiting covers 55 are provided on the side of the ventilation door 52 facing inwards from the cabinet 1. Multiple air passage holes 56 are provided on the limiting covers 55, and a fan 57 is rotatably installed within each air passage hole 56. An isolation cover 58 is provided over the limiting covers 55, located on the inner side of the cabinet 1. An isolation grid 581 is provided on the side of the isolation cover 58 facing inwards from the cabinet 1. A platform grid 582 is provided on the isolation cover 58. Ventilation holes 59 are provided at the top and bottom of the isolation cover 58. When fan 57 rotates, it draws hot air from inside the cabinet 1 into the limiting cover 55 through the air vent 56, and then exhausts it outside the cabinet 1 through the ventilation holes 59 of the isolation cover 58. The isolation grille 581 and the exhaust grille 54 prevent dust and debris from entering the cabinet 1, protecting the electrical components. Fan 57 can be an axial fan 57, which has high airflow and pressure; or it can be a centrifugal fan 57, which is suitable for spaces with limited space.

[0034] The placement module 4 includes a fixed frame 41. The fixed frame 41 is fixedly installed on the side of the cabinet 1 away from the limiting cover 55. A support plate 42 and a fixing box 43 are positioned between the fixed frame 41 and the isolation cover 58. One end of the support plate 42 rests on the top of the platform grille 582, and the other end is fixedly connected to the upper part of the fixed frame 41. One end of another support plate 42 rests on the bottom of the platform grille 582, and the other end is fixedly connected to the lower part of the fixed frame 41. A placement groove 583 is provided in the middle of the fixed frame 41, and a fixing box 43 is inserted into the placement groove 583. The other end of the fixing box 43 is fixedly connected to the middle of the fixed frame 41. The support plate 42 is used to support electrical components, and the fixing box 43 can be used to place important electrical components, such as power modules and control units. The support plate 42 can be made of metal, such as steel plate, to ensure its load-bearing capacity; or it can be made of high-strength plastic to reduce weight. The fixing box 43 can be made of insulating material to prevent electromagnetic interference between electrical components.

[0035] A limit plate 44 is provided on the side of the isolation cover 58 and the fixing frame 41 facing the switch door 2, and multiple mounting brackets 45 are provided on the limit plate 44. The barrier plate can further prevent electromagnetic interference, and the limit plate 44 plays a role in fixing and limiting the barrier plate. The mounting brackets 45 can be used to install other auxiliary equipment, such as sensors. The barrier plate can be made of electromagnetic shielding materials, such as copper mesh or aluminum foil; the mounting brackets 45 can be designed into different shapes and sizes as needed to adapt to the installation requirements of different equipment.

[0036] The implementation principle of this embodiment is as follows: The charging pile in this embodiment, through the unique locking module 3 design, facilitates the installation and disassembly of the opening and closing door 2, improves operational efficiency, and is not easily loosened or damaged during long-term use. The cooling module 5 adopts structures such as ventilation slots 51, fans 57, and isolation covers 58 to achieve efficient heat dissipation, ensuring the normal operating temperature of the electrical components inside the cabinet 1 and extending the service life of the electrical components. The placement module 4, through a reasonable layout, adopts structures such as a bearing plate 42 and a fixing box 43 to precisely control the safe distance between each electrical component, avoiding electromagnetic interference, while compressing the lateral space and realizing the miniaturization design of the charging pile. The electrical control module 6 is connected to the electrical components in the placement module 4 by electrical signals to ensure the normal charging function of the charging pile. The overall structural layout is reasonable, and all components work together, which significantly improves performance and practicality compared to traditional charging piles, meeting the market demand for efficient, stable, and miniaturized charging piles. Example 2

[0037] like Figure 1 As shown, the difference between this embodiment and the above embodiments lies in that the locking module 3 can adopt a magnetic locking method. The magnetic locking module 3 includes a magnetic block disposed on the inside of the switch door 2 and a magnetic base disposed at the corresponding position on the cabinet 1. The magnetic block and the magnetic base attract each other through magnetic force, thereby locking the switch door 2 to the cabinet 1. The magnetic block can be made of a strong permanent magnet material, such as neodymium iron boron, to ensure sufficient attraction; the magnetic base can be made of a ferromagnetic material, such as iron or steel. This magnetic locking method is more convenient to install and disassemble, eliminating the need for manual operation of rotating parts. Simply bring the switch door 2 close to the cabinet 1, and the magnetic block and magnetic base will automatically attract together. At the same time, the magnetic locking method is less prone to loosening and damage during long-term use, improving the stability and reliability of use.

[0038] The implementation principle of this embodiment is as follows: The magnetic locking module 3 utilizes the principle of magnetic attraction to achieve rapid locking and unlocking of the door 2 and the cabinet 1, making operation simpler. Compared with traditional mechanical locking methods, the magnetic locking method reduces wear and tear and the probability of failure of mechanical parts, improving the maintenance convenience and service life of the charging pile. At the same time, the magnetic locking method does not generate noise during mechanical transmission, enhancing the user experience. In the overall structure of the charging pile, the magnetic locking module 3 works in conjunction with other parts to ensure the normal operation of the charging pile and the optimized layout of its internal structure.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
