One of the core components of a charging pile is a rectification module, which is responsible for converting alternating current into direct current to provide a stable power supply for electric vehicles. However, there are some problems with the existing rectification modules of charging piles in terms of installation, maintenance, and replacement, which affect the operation efficiency and maintenance cost of the charging piles.
[0003] Traditional rectification modules of charging piles usually adopt a fixed installation method, directly fixing the modules inside the charging piles. This structure has the following disadvantages:
[0004] (1) Inconvenient installation and disassembly: Due to the large volume and self-weight of the modules and limited internal space, it takes a lot of time and manpower to install and disassemble the modules, and the operation is inconvenient.
[0005] (2) Difficult maintenance: When the rectification module fails, it needs to be completely disassembled from inside the charging pile for repair or replacement, which is time-consuming and laborious, affecting the normal operation of the charging pile.
[0006] (3) Heat dissipation problem: A large amount of heat is generated during the operation of the rectification module. If the heat dissipation is poor, it will affect the performance and service life of the module. The traditional fixed installation method is not conducive to the heat dissipation of the module and easily causes the module to overheat.
[0007] (4) Low space utilization rate: The traditional fixed installation method occupies a large amount of space inside the charging pile, which is not conducive to the compact design of the charging pile. Content of the Utility Model
[0008] In order to solve the above problems, the utility model provides a drawable structure of a rectification module of a charging pile, which reduces the manufacturing cost and realizes the quick plugging and unplugging and maintenance of the rectification module.

Detailed Embodiment
[0027] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.
[0028] As Figures 1 to 7 shown, the extraction structure of the rectifier module 200 of the charging pile described in this embodiment includes a charging pile body 100 and a rectifier module 200. The charging pile body 100 is provided with an inner cavity 101 and a first opening 102 on the outer side wall. A vertical middle partition 10 is provided in the inner cavity 101. The middle partition 10 divides the inner cavity 101 into a rectification chamber 20 and a maintenance chamber 30. The first opening 102 communicates with the rectification chamber 20, and the opening direction of the first opening 102 is the same as the length direction of the charging pile body 100.
[0029] At least two positions 21 are arranged at intervals in the height direction of the charging pile body 100 in the rectification chamber 20. Each position 21 is enclosed by two relatively arranged partition units 40 and the middle partition 10, forming a space for the rectifier module 200 to slide in and out.
[0030] Each partition unit 40 includes a first side 41, a second side 42, two short sides, and two long sides extending in the opening direction of the first opening 102. The long sides are bent towards the first side 41 to form a first folded edge 43, and the short sides are bent towards the second side 42 to form a second folded edge 44. A number of guide posts 45 are arranged at intervals in the opening direction of the first opening 102 on the first side 41. The two second folded edges 44 of the partition unit 40 are respectively fixed to the outer side wall and the middle partition 10 of the charging pile body 100, enhancing the structural stability.
[0031] A rectifier module socket 11 adapted to the rectifier module 200 is fixedly installed on the middle partition 10. The rectifier module 200 can be installed in the position 21 in a drawable manner along the first opening 102, facilitating quick installation and replacement.
[0032] When it is necessary to install the rectifier module 200 or perform necessary maintenance, the rectifier module 200 is only required to slide in and out of the corresponding module position 21 from the first opening 102. During this process, the first folded edge 43 and the guide posts 45 can guide the insertion direction of the rectifier module 200 and ensure the correct positioning of the rectifier module 200.
[0033] In this way, the storage space 21 is constructed using the standardized partition unit 40. When the rectification module 200 is installed in the rectification chamber 20, that is, in the storage space 21, only the side surface of the rectification module 200 contacts the first folded edge 43 and the guide post 45, reducing the contact area, thereby reducing the resistance to the movement of the rectification module 200 and making it easier to install and extract. At the same time, the arrangement of the guide post 45 on the partition unit 40 divides a storage space 21 into two separated sub-compartments (not shown in the figure). The diameter of the guide post 45 ensures a reasonable heat dissipation distance between two rectification modules 200 placed in the same storage space 21.
[0034] This structural design uses the standardized partition unit 40, reducing the number of components and avoiding complex guide rail grooves or protective structures, simplifying the structure, reducing the manufacturing cost. Also, it can reduce the thickness in the front-back (width) direction while keeping the overall height of the charging pile body 100 unchanged, reducing the overall external dimensions, further saving materials and reducing costs.
[0035] In addition, the middle partition 10 not only divides the rectification chamber 20 for accommodating the rectification module 200, but also divides a maintenance chamber 30. In this embodiment, the maintenance chamber 30 is mainly used to accommodate other electronic components and circuits of the charging pile, facilitating the connection of the rectification module socket 11 to, for example, a control board, a communication module, a power module, etc., and providing a separate space for the maintenance and repair of these components.
[0036] In some embodiments, as Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 shown, a flanging 46 extending along the opening direction of the first opening 102 is provided on the second side 42 of the partition unit 40, and the flanging 46 is integrally formed by stamping the partition unit 40.
[0037] During specific implementation, the flanging 46 is integrally formed with the partition unit 40 by stamping. This design not only simplifies the manufacturing process and reduces the production cost, but also significantly improves the structural performance of the partition unit 40. Specifically, the integrally formed flanging 46 increases the sectional moment of inertia of the partition unit 40, thereby enhancing its ability to resist bending deformation. In practical applications, the partition unit 40 needs to bear the weight of the rectification module 200 and the forces generated during the plugging and unplugging process. The existence of the flanging 46 can effectively disperse these stresses, avoid stress concentration, and prevent local deformation or fracture of the partition unit 40. In addition, the flanging 46 also improves the overall rigidity of the partition unit 40, making it more stable and less likely to shake, which is crucial for ensuring the stable installation of the rectification module 200 with a relatively large self-weight.
[0038] In this embodiment, as Figure 4 、 Figure 5 、 Figure 6As shown, a plurality of flanges 46 are provided on each partition unit 40, and at least one flange 46 is provided between the guide post 45 and each of the two long sides. In an actual application scenario, when the rectifier module 200 is inserted into or removed from the module bin 21, lateral forces will inevitably be generated. If these lateral forces are not effectively controlled, they may cause the partition unit 40 to twist and deform, affecting the smoothness of module insertion and removal, and even causing the module to get stuck or damaged. By providing a plurality of flanges 46, especially the flanges 46 located between the guide post 45 and the long sides, these lateral forces can be effectively dispersed, enhancing the torsional stiffness of the partition unit 40 and maintaining its shape stability, thereby ensuring the smooth insertion and removal of the rectifier module 200.
[0039] In some embodiments, the guide post 45 is a press riveting post, and a prefabricated hole adapted to the press riveting post is provided on each partition unit 40. Specifically, during the production of the partition unit 40, the prefabricated hole is formed by a stamping process in one step, without subsequent drilling, tapping and other processes. That is, in the assembly stage, only the press riveting post 45 needs to be inserted into the corresponding prefabricated hole, and then pressure is applied by a press riveting device to firmly fix the press riveting post 45 on the partition unit 40. This press riveting installation method is simpler and faster compared to traditional screw fixing or welding methods, eliminating cumbersome additional processes such as drilling, tapping and welding, greatly shortening the production time, reducing labor costs and material costs, and the reliability of the press riveting connection is also very high. Even frequent pulling and pushing of the rectifier module 200 will not cause the press riveting post 45 to become loose.
[0040] In some embodiments, a guide sleeve (not shown in the figure) is sleeved outside the guide post 45, and the guide sleeve is coaxially arranged with the guide post 45 and can rotate relative to it. In an actual application scenario, the rectifier module 200 is usually relatively heavy, and directly inserting or removing it from the module bin 21 requires overcoming a large frictional force, making the operation rather laborious. In addition, repeated insertion and removal operations will cause wear on the contact surface between the guide post 45 and the rectifier module 200, shortening its service life. The addition of the guide sleeve can convert the sliding friction between the guide post 45 and the rectifier module 200 into rolling friction. That is, when inserting or removing the rectifier module 200, the rectifier module 200 contacts the guide sleeve, and the guide sleeve can freely rotate around the guide post 45, greatly reducing the frictional resistance between the module and the guide post 45 and making the insertion and removal operations smoother. Even a heavy rectifier module 200 can be easily inserted or removed.
[0041] In some embodiments, such as Figure 6 、 Figure 7As shown, at least one maintenance opening 12 is provided on the middle partition plate 10. During specific implementation, the opening size of the maintenance opening 12 is designed to be larger than the size of the rectifier module socket 11, so as to facilitate the operation and maintenance of the socket 11. For example, when it is necessary to replace a damaged socket 11, check its line connection or perform cleaning, technicians only need to open the maintenance opening 12 to directly access the socket 11 and perform corresponding operations, without having to disassemble the entire middle partition plate 10 or other components. This design greatly simplifies the maintenance process, improves the maintenance efficiency, and also reduces the maintenance cost.
[0042] In some embodiments, as Figure 7 shown, on the other outer side wall of the charging pile body 100 opposite to the first open end 102, a second open end 103 is further provided, and the second open end 103 communicates with the maintenance room 30; two side plates 104 arranged vertically and fixed on both sides of the middle partition plate 10 are provided in the maintenance room 30, and the side of the side plate 104 facing away from the middle partition plate 10 is fixedly connected to the charging pile body 100. This design clearly divides the internal space of the charging pile. The installation and maintenance of the rectifier module 200 are carried out through the first open end 102, while other electronic components and circuits are installed in the maintenance room 30 formed by enclosing the side plate 104 and the middle partition plate 10, and the maintenance and repair are carried out through the second open end 103. Such a partition design brings many benefits: First, it effectively isolates the rectifier module 200 and other electronic components, avoiding mutual interference. For example, when it is necessary to repair the control circuit or other electronic components, maintenance personnel can directly enter the maintenance room 30 through the second open end 103 without touching or moving the rectifier module 200, thereby reducing the risk of misoperation and improving the maintenance efficiency; Second, the presence of the side plate 104 enhances the structural strength and stability of the maintenance room 30 and provides a platform for installing and supporting internal electronic components, which makes the internal layout of the maintenance room 30 more regular and easier to dissipate heat.
[0043] In some embodiments, as Figure 2 , Figure 3 , Figure 6 , Figure 7As shown, the rectifier module 200 is provided with a vertically extending limiting edge 201 on one side facing the first opening 102 . When the rectifier module 200 is installed in the bin 21 , the limiting edge 201 abuts against the second folded edge 44 of the partition unit 40 and is fixedly connected by a hand screw 202 . In this embodiment, the use of the limiting edge 201 and the hand screw 202 realizes the precise positioning and firm installation of the rectifier module 200 in the bin 21, that is, when the rectifier module 200 is inserted into the bin 21, the limiting edge 201 on the module will contact the second folding edge 44 of the partition unit 40. This contact not only provides a clear indication of the position of the module to the operator, indicating that the module has been pushed into the correct position, but also limits the movement range of the module in the bin, so that it can only be installed in a predetermined position, effectively preventing the module from being installed in an inadequate or misplaced position; and the use of the hand screw 202 to fix the limiting edge 201 and the second folding edge 44 further enhances the installation firmness of the module, and ensures that the module will not loosen or fall off even when subjected to a large external force. In addition, the design of the hand screw 202 also facilitates the operator to install and disassemble by hand without the help of any tools, thereby improving maintenance efficiency.
[0044] In this embodiment, if Figure 2 , Figure 3 As shown, the rectifier module 200 is further provided with a handle 203 on one side facing the first opening 102. The handle 203 provides a convenient gripping point for operators, allowing them to more easily grasp the rectifier module 200. The handle 203 is more effective when the module is heavy or the space is narrow.
[0045] The extractable structure of the charging pile rectifier module provided in this embodiment is separated into multiple independent positions by setting multiple standardized partition units, which reduces the manufacturing cost and realizes the rapid plug-in and maintenance of the rectifier module, so that each rectifier module can slide in or out independently from the outside of the charging pile, and the parameters can be set directly at the rear end, which is convenient and fast; at the same time, this design reduces the thickness in the front and rear directions and the overall dimensions while ensuring that the overall height of the charging pile remains unchanged, thereby reducing the material cost. In addition, the position is constructed with flanging and riveting columns, which reduces the contact area between the position and the rectifier module, thereby reducing the resistance during installation and extraction, making the operation more convenient, and also improving the heat dissipation performance, extending the module life, and improving the space utilization, making the charging pile more compact.
