[0020] It should also be noted that, unless otherwise explicitly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] The existing charging module fixing process suffers from problems such as limited internal space in the charging compartment and difficulties in installation and maintenance.

[0022] In view of this, to solve the above problems, please refer to Figure 1 , Figure 2As shown in the figure, this application embodiment provides a charging pile internal module fixing structure, including: a housing 10, a charging module 11 disposed inside the housing 10, a first limiting structure 12 and a second limiting structure 13 respectively disposed between the charging module 11 and the housing 10, the first limiting structure 12 is arranged along the x direction, the second limiting structure 13 is disposed along the y direction on the opposite side of the first limiting structure 12, and a third limiting structure is disposed on the housing 10 along the z direction, the first limiting structure 12, the second limiting structure 13 and the third limiting structure respectively limit the charging module 11 in the x, y and z directions inside the housing 10.

[0023] The housing 10 is a hollow, semi-enclosed shell with an opening, and the opening of the housing 10 can be closed by a top cover; the hollow area inside the housing 10 forms a charging compartment, and the charging module 11 is placed inside the charging compartment. For example, the housing 10 is a hollow rectangular structure with four inner side walls and an inner bottom wall, and the charging compartment is formed by the aforementioned inner walls of the housing 10.

[0024] The first limiting structure 12 and the second limiting structure 13 are located between the housing 10 and the charging module 11; wherein, the first limiting structure 12 is arranged along the x-direction and can limit the charging module 11 in the x-direction within the housing 10; the second limiting structure 13 is arranged opposite to the first limiting structure 12 in the y-direction and limits the charging module 11 in the y-direction within the housing 10.

[0025] The first limiting structure 12 and the second limiting structure 13 fix the charging module 11 within the bottom surface of the housing 10, i.e., in the xy plane. In addition, a third limiting structure is provided at the opening of the housing 10, which limits the charging module 11 within the housing 10 along the z direction.

[0026] In this way, the first limiting structure 12, the second limiting structure 13, and the third limiting structure can limit the charging module 11 in the x, y, and z directions within the housing 10, thereby firmly fixing the charging module 11 within the housing 10. Furthermore, the first limiting structure 12, the second limiting structure 13, and the third limiting structure use non-screw-type fasteners, allowing the charging module 11 to be released without removing the fasteners. This enables rapid maintenance and replacement of the charging module 11, reduces safety hazards caused by screw-type fasteners or metal shavings falling during disassembly and assembly, and ensures the safe use of the charging pile's internal module fixing structure.

[0027] Specifically, the first limiting structure 12 includes two slots 121 formed on the inner sidewall of the housing 10. The two slots 121 are symmetrically arranged along the x-direction, and the two ends of the charging module 11 along the x-direction are respectively engaged in the two slots 121.

[0028] The inner sidewall of the housing 10 forms two slots 121. For example, the housing 10 along... Figure 2 Two protrusions 120 are provided at the bottom in the y-direction, and a slot 121 is formed on the protrusions 120. The slot 121 engages with the edge of the end of the charging module 11 in the x-direction to constrain and limit the charging module 11 in the x-direction. By using the slot 121, there is no need for drilling or screw fixing, which makes the charging module 11 securely engaged in the housing 10, and also facilitates disassembly and assembly.

[0029] In some embodiments, such as Figure 3 As shown, the projection of the card slot 121 along the z-direction is L-shaped, so that the card slot 121 forms an L-shaped card slot. The right-angle structure of the L-shaped card slot can effectively utilize the corner space of the protrusion 120, avoid space waste, and is suitable for use in miniaturized scenarios.

[0030] Reference Figure 4 As shown, the second limiting structure 13 includes two clamping components arranged along the x-direction; the clamping components include a boss 131 formed on the inner sidewall of the housing 10 and facing the charging module 11 along the y-direction, and an adjustable clamping member 132 connected to the boss 131, the clamping member 132 clamping the charging module 11 along the y-direction.

[0031] The clamping assembly is used to clamp the charging module 11 along the y-direction to limit the charging module 11 along the y-direction. For example, the clamping assembly includes a boss 131 and a clamping member 132. The boss 131 is formed on the inner sidewall of the housing 10 and protrudes toward the charging module 11 along the y-direction. The clamping member 132 is connected to the boss 131 and clamps the charging module 11.

[0032] Furthermore, the clamping member 132 can also move along the y-direction to achieve adjustable settings in the y-direction. This makes it convenient to leave space and to assemble and disassemble the charging module 11 and the clamping member 132 when the clamping member 132 and the charging module 11 are separated. When it is necessary to clamp the charging module 11, the movement of the clamping member 132 can also clamp the charging module 11.

[0033] Furthermore, such as Figure 5 As shown, a first nut 133 is provided on the boss 131 by riveting or welding. The clamping member 132 includes a pressure plate 1321 close to the charging module 11 and a screw 1320 connected to the pressure plate 1321. The screw 1320 is threadedly engaged with the first nut 133, and the pressure plate 1321 presses against the charging module 11.

[0034] The screw 1320 engages with the first nut 133 to achieve a threaded connection. By tightening the knob 132, the pressure plate 1321 contacts the charging module 11 and applies pressure to the charging module 11, thereby tightening the charging module 11 and providing constraint in the y-direction. The threaded connection structure is simple, easy to assemble and disassemble without the need for additional tools, convenient for maintenance, and has high reliability.

[0035] Based on this, the screw 1320 is generally made of metal, specifically carbon steel, with a corrosion-resistant surface treatment to improve its structural rigidity and hardness. The pressure plate 1321, since it comes into contact with the charging module 11, can be made of non-metallic materials, such as engineering plastics or nylon, with a surface hardness lower than that of metal. This prevents scratching the charging module 11 during the pressing process.

[0036] In some embodiments, a second nut 1323 may be provided between the screw 1320 and the first nut 133. The second nut 1323 is disposed on the screw 1320 and threadedly engages with the screw 1320. During operation, the second nut 1323 is tightened in the reverse direction. The second nut 1323 and the first nut 133 form a double-nut locking structure, which can improve the anti-loosening capability between the screw 1320 and the first nut 133, prevent the screw 1320 and the pressure plate 1321 from failing to tighten under long-term vibration, and further improve the reliability of the connection.

[0037] In addition, a flange 1322 is provided at the end of the screw 1320 near the pressure plate 1321. The flange 1322 is used to connect a knob tool. The flange 1322 can be a hexagonal flange or a four-sided flange, etc. When tightening or loosening the clamping member 132, the flange 1322 and the screw 1320 should always move synchronously. The function of the flange 1322 is to facilitate disassembly and assembly by using a tool to turn the screw 1320 when a larger preload is required.

[0038] The third limiting structure includes a pressure plate 141 disposed on the housing 10. The pressure plate 141 is used to press the charging module 11 along the z direction. An air duct 15 is also formed between the pressure plate 141 and the housing 10 along the z direction. The charging module 11 has a first air outlet 110, which faces the air duct 15.

[0039] For example, such as Figure 2 , Figure 3 As shown, the pressure plate 141 is installed at the opening of the housing 10 through the fixing hole 122 provided on the protrusion 120, and presses the charging module 11 to achieve the limiting of the charging module 11 along the z direction.

[0040] Meanwhile, the charging compartment of the housing 10 also forms an air duct 15 in the area of ​​the pressure plate 141. The first air outlet 110 of the charging module 11 faces the air duct 15, and the air duct 15 is connected to the outside of the housing 10 through the second air outlet 100 on the housing 10. When the charging module 11 dissipates heat, the heat is dissipated to the outside of the housing 10 through the first air outlet 110, the air duct 15, and the second air outlet 100. The pressure plate 141 is fastened to the air duct 15, which isolates the air duct 15 and prevents the heat in the air duct 15 from dissipating to other areas inside the housing 10 and affecting the operation of components in other areas.

[0041] The third limiting structure also includes a mounting plate 142 disposed on the charging module 11. The mounting plate 142 has a flange 1420 formed along the z-direction toward the charging module 11, and the flange 1420 presses against the charging module 11.

[0042] The mounting plate 142 and the aforementioned pressure plate 141 can simultaneously press the charging module 11 to achieve directional constraint on the charging module 11. The mounting plate 142 is located above the charging module 11 and is used to mount related components. The mounting plate 142 forms a flange 1420 along the z-direction, which presses the charging module 11 below it.

[0043] It should be noted that the fixing screws of the pressure plate 141 and the mounting plate 142 are all located on the outside of the housing 10. The housing 10 does not have a deep mounting position, and the probability of the screws falling into the housing 10 is extremely small, which can improve the reliability of the whole machine.

[0044] The aforementioned first limiting structure 12, second limiting structure 13, and third limiting structure cooperate to constrain the charging module 11 in the y and z directions, ensuring that the charging module 11 can be securely fixed inside the housing 10. Furthermore, the clamping member 132 is adjustable, and the fixing screws of the pressure plate 141 and mounting plate 142 are located outside the housing 10. Therefore, the installation, fixing, and disassembly of the charging module 11 can be completed without entering the housing 10, greatly improving the convenience and safety of maintenance.

[0045] When assembling and disassembling the internal module fixing structure of the charging pile in this application, before installing the charging module 11 into the housing 10, the tightening member 132 is screwed in first to ensure sufficient space between the pressure plate 1321 and the charging module 11. After placing the charging module 11 into the housing 10, the two edges at the bottom of the charging module 11 are aligned with the two slots 121. At this time, the charging module 11 is only constrained in the x-direction. When the tightening member 132 is screwed out until the pressure plate 1321 presses against the top surface of the charging module 11, the y-direction is also constrained. Then, the pressure plate 141 and the mounting plate 142 are used to constrain the direction of the charging module 11.

[0046] When maintenance or replacement of the charging module 11 is required, simply reverse the operation. First, loosen the external fixing screws of the mounting plate 142 and the pressure plate 141, then rotate the clamping member 132 to disengage the pressure plate 1321 from the top surface of the charging module 11, and the charging module 11 can be easily removed without entering the machine compartment.

[0047] This design not only enables rapid maintenance and replacement of the charging module 11, but also reduces safety hazards caused by falling screws or metal shavings, improving the overall reliability and maintenance efficiency of the device.

[0048] On the other hand, in addition to the above, the clamping components Figure 5 In addition to the structure shown, the clamping component may also take other forms in other embodiments.

[0049] Specifically, when charging stations are used in underground parking lots of large commercial centers, the humid environment and confined space present a unique challenge for maintenance personnel when replacing the charging module 11: the clamping part 132 is prone to corrosion after long-term use, making it difficult to rotate and adjust. This not only increases the difficulty of maintenance but may also create a safety hazard due to unstable fixing of the charging module 11. The humid environment accelerates the oxidation process of metal components, while the confined space limits the angle and force applied by maintenance personnel, making the removal of the corroded clamping part 132 a time-consuming and difficult task. This problem transforms the design, originally intended to improve maintenance convenience, into an obstacle to maintenance in this specific environment.

[0050] Therefore, in order to solve the problem of adjustment difficulty caused by the corrosion of the clamping member 132, the clamping member 132 includes a rust-proof shell, an elastic member and a pressure plate 1321. The outer wall of the rust-proof shell is provided with threads to cooperate with the first nut 133. The elastic member and the pressure plate 1321 are provided inside the rust-proof shell. The pressure plate 1321 is connected to the elastic member. The pressure plate 1321 is located close to the charging module 11 and protrudes from the rust-proof shell in the y direction.

[0051] The rust-proof outer shell can be made of high-strength engineering plastic. It is cylindrical in shape and hollow inside. The outer wall of the rust-proof outer shell is threaded, which can directly mate with the threaded hole of the first nut 133 on the boss 131 on the inner side wall of the housing 10. The rust-proof outer shell has an opening on the side facing the charging module 11, through which the pressure plate 1321 can be extended.

[0052] The elastic element, typically a spring, is built into the rust-resistant housing. One end of the elastic element is fixed to the end of the housing facing the boss 131, and the other end is connected to the pressure plate 1321. The strength of the spring is precisely calculated to provide sufficient pressure to fix the charging module 11, while allowing a certain degree of compression to accommodate charging modules 11 of different thicknesses.

[0053] The pressure plate 1321 is basically the same as the pressure plate 1321 in the previous embodiment, and can be made of wear-resistant and rust-proof materials, such as stainless steel or metal with a special coating. The end of the pressure plate 1321 facing the charging module 11 protrudes slightly from the rust-proof housing for direct contact and pressing against the charging module 11.

[0054] During installation, simply screw the rust-proof outer shell into the first nut 133 of the boss 131 on the housing 10. Because the rust-proof outer shell is made of plastic, it will not rust even in humid environments. After the charging module 11 is inserted into the housing 10, the pressure plate 1321 automatically presses the charging module 11 under the action of a spring. If pressure adjustment is required, the height position of the pressure plate 1321 along the y-direction can be changed by rotating the entire housing.

[0055] The aforementioned design eliminates the corrosion problem of the metal screw 1320 and improves the long-term reliability of the clamping component 132. The elastic element provides adaptive pressure, compensating for dimensional deviations between different charging modules 11 and enhancing the system's flexibility. The integrated rotary adjustment method allows for easy pressure adjustment of the pressure plate 1321 on the charging module 11 even in confined spaces, reducing the number of components requiring frequent adjustment and simplifying the maintenance process.

[0056] This effectively solves the adjustment difficulties caused by the corrosion of the clamping component 132 in humid environments, while maintaining the advantages of quick installation and disassembly of the original charging module 11, further improving the maintenance efficiency and reliability of the internal module fixing structure of the charging pile in various environments.

[0057] Based on this, the present application also discloses a charging device, including the internal module fixing structure of the charging pile as described above.

[0058] For example, charging equipment can be charging piles, which provide charging services for electric vehicles. Multiple charging piles can also communicate and interconnect to form a charging station.

[0059] For example, multiple charging piles can be interconnected through communication methods such as wireless communication and wired communication. Multiple charging piles can send, forward or upload data through communication interconnection to meet the charging needs of multiple vehicles and perform management functions.

[0060] The charging device includes the same structure and beneficial effects as the internal module fixing structure of the charging pile in the foregoing embodiments. The structure and beneficial effects of the internal module fixing structure of the charging pile have been described in detail in the foregoing embodiments and will not be repeated here.

[0061] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
