[0002] In the existing technology, DC charging piles are important infrastructure for providing fast charging for electric vehicles. With the popularity of electric vehicles, the demand for charging piles is also growing. One of the core components of the charging pile is the rectifier module, which is responsible for converting AC power into DC power to provide a stable power supply for electric vehicles. However, there are some problems with the installation, maintenance and replacement of the existing charging pile rectifier modules, which affect the operating efficiency and maintenance cost of the charging pile.

[0003] Traditional charging pile rectifier modules are usually fixed in a fixed installation mode, where the module is directly fixed inside the charging pile. This structure has the following disadvantages:

[0004] (1) Inconvenient installation and disassembly: Due to the large size and weight of the module and the limited internal space, installing and disassembling the module requires a lot of time and manpower, and the operation is inconvenient.

[0005] (2) Difficult maintenance: When a rectifier module fails, it needs to be completely removed from the charging pile for repair or replacement, which is time-consuming and labor-intensive, affecting the normal operation of the charging pile.

[0006] (3) Heat dissipation problem: The rectifier module generates a lot of heat during operation. If the heat dissipation is not good, it will affect the performance and 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: The traditional fixed installation method occupies a large space inside the charging pile, which is not conducive to the compact design of the charging pile. Summary of the invention

[0010] In order to enhance the strength of the partition unit, a flange extending along the first opening direction is provided on the second side of the partition unit, and the flange is formed by integrally stamping the partition unit.

[0011] A further solution is that each of the partition units is provided with a plurality of flanges, and at least one flange is provided between the guide column and the two long sides.

[0012] In order to simplify the installation process of the guide column, the guide column is a pressure-riveted column, and each of the partition units is provided with a prefabricated hole that is compatible with the pressure-riveted column.

DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention are 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 invention, and are not used to limit the present invention.

[0028] like Figures 1 to 7 As shown, the charging pile rectifier module 200 described in this embodiment has an extractable structure, including 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 located on the outer wall, the inner cavity 101 is provided with a vertically arranged middle partition 10, the middle partition 10 divides the inner cavity 101 into a rectifier chamber 20 and a maintenance chamber 30; the first opening 102 is connected to the rectifier 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] The rectifier chamber 20 is provided with at least two compartments 21 arranged at intervals along the height direction of the charging pile body 100. Each compartment 21 is enclosed by two oppositely arranged partition units 40 and the middle partition 10, forming a space for the rectifier module 200 to slide in and out.

[0030] Each of the partition units 40 includes a first side 41, a second side 42, two short sides and two long sides extending along the opening direction of the first opening 102. The long side is bent toward the first side 41 to form a first folded edge 43, and the short side is bent toward the second side 42 to form a second folded edge 44. The first side 41 is provided with a plurality of guide columns 45 arranged at intervals along the opening direction of the first opening 102. The two second folded edges 44 of the partition unit 40 are respectively fixed to the outer wall of the charging pile body 100 and the middle partition 10, thereby enhancing the stability of the structure.

[0031] A rectifier module socket 11 adapted to the rectifier module 200 is fixedly mounted on the middle partition 10; the rectifier module 200 can be installed in the bin 21 along the first opening 102 in a pull-out manner, so that it can be installed and replaced conveniently and quickly.

[0032] When the rectifier module 200 needs to be installed or necessary maintenance needs to be performed, the rectifier module 200 only needs to be slid from the first opening 102 into and out of the corresponding module compartment 21. During this process, the first folded edge 43 and the guide column 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 bin 21 is constructed using a standardized partition unit 40. When the rectifier module 200 is installed in the rectifier chamber 20, i.e., the bin 21, the side of the rectifier module 200 only contacts the first folded edge 43 and the guide column 45, and the contact area is reduced, thereby reducing the resistance to the movement of the rectifier module 200, making it easier to install and extract; at the same time, the setting of the guide column 45 on the partition unit 40 divides a bin 21 into two spaced sub-bins (not shown in the figure), and the diameter of the guide column 45 ensures a reasonable heat dissipation distance between the two rectifier modules 200 placed in the same bin 21.

[0034] This structural design adopts a standardized partition unit 40, which reduces the number of parts and avoids complex guide grooves or protective structures, simplifies the structure, and reduces manufacturing costs. It can also reduce the thickness in the front-to-back (width) direction while ensuring that the overall height of the charging pile body 100 remains unchanged, reducing the overall external dimensions, further saving materials and reducing costs.

[0035] In addition, the middle partition 10 not only separates the rectifier chamber 20 for accommodating the rectifier module 200, but also separates a maintenance chamber 30. In the present embodiment, the maintenance chamber 30 is mainly used to accommodate other electronic components and circuits of the charging pile, and facilitates the connection between the rectifier module socket 11 and, for example, a control board, a communication module, a power module, etc., and provides space for separate inspection and maintenance of these components.

[0036] In some embodiments, Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a flange 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 flange 46 is formed by integrally stamping the partition unit 40 .

[0037] In specific implementation, the flange 46 is stamped integrally with the partition unit 40. This design not only simplifies the manufacturing process and reduces production costs, but also significantly improves the structural performance of the partition unit 40. Specifically, the integrally stamped flange 46 increases the cross-sectional moment of inertia of the partition unit 40, thereby enhancing its ability to resist bending deformation. In actual applications, the partition unit 40 needs to bear the weight of the rectifier module 200 and the force generated during the plugging and unplugging process. The presence of the flange 46 can effectively disperse these stresses, avoid stress concentration, and prevent the partition unit 40 from local deformation or fracture. In addition, the flange 46 also improves the overall rigidity of the partition unit 40, making it more stable and less prone to shaking, which is crucial to ensure the stable installation of the rectifier module 200 with a large dead weight.

[0038] In this embodiment, if Figure 4 , Figure 5 , Figure 6As shown, each of the partition units 40 is provided with a plurality of flanges 46, and at least one flange 46 is provided between the guide column 45 and the two long sides. In actual application scenarios, when the rectifier module 200 is inserted into or removed from the module compartment 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 the module insertion and removal, and even causing the module to get stuck or damaged. The provision of a plurality of flanges 46, especially the flanges 46 located between the guide column 45 and the long sides, can effectively disperse these lateral forces, enhance the torsional rigidity of the partition unit 40, and maintain its shape stability, thereby ensuring smooth insertion and removal of the rectifier module 200.

[0039] In some embodiments, the guide column 45 is a rivet column, and each of the partition units 40 is provided with a prefabricated hole that matches the rivet column. In specific implementation, in the process of producing the partition unit 40, the prefabricated hole is formed in one go through a stamping process, without the need for subsequent drilling, tapping and other processes, that is, in the assembly stage, it is only necessary to insert the rivet column 45 into the corresponding prefabricated hole, and then use the rivet equipment to apply pressure, so that the rivet column 45 can be firmly fixed on the partition unit 40; this rivet installation method is simpler and faster than the traditional screw fixing or welding method, eliminating the tedious drilling, tapping, welding and other additional processes, greatly shortening the production time, reducing labor costs and material costs, and the reliability of the rivet connection is also very high, even if the rectifier module 200 is frequently pulled out, it will not cause the rivet column 45 to loosen.

[0040] In some embodiments, the outer side of the guide column 45 is provided with a guide sleeve (not shown), and the guide sleeve is coaxially arranged with the guide column 45 and can rotate relative to each other. In actual application scenarios, the rectifier module 200 is usually heavy, and directly inserting or removing it from the module compartment 21 requires overcoming a large friction force, which is laborious to operate. In addition, repeated plugging and unplugging operations will also cause the contact surface of the guide column 45 and the rectifier module 200 to wear, shortening its service life. The addition of the guide sleeve can convert the sliding friction between the guide column 45 and the rectifier module 200 into rolling friction, that is, when the rectifier module 200 is inserted or pulled out, the rectifier module 200 contacts the guide sleeve, and the guide sleeve can rotate freely around the guide column 45, so as to greatly reduce the friction resistance between the module and the guide column 45, making the plugging and unplugging operation smoother, and even a heavy rectifier module 200 can be easily inserted or pulled out.

[0041] In some embodiments, Figure 6 , Figure 7As shown, at least one inspection port 12 is provided on the middle partition 10. In specific implementation, the opening size of the inspection port 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 clean it, the technician only needs to open the inspection port 12 to directly access the socket 11 and perform the corresponding operation without disassembling the entire middle partition 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, Figure 7 As shown, the charging pile body 100 is provided with a second opening 103 on another outer side wall opposite to the first opening 102, and the second opening 103 is connected to the maintenance room 30; the maintenance room 30 is provided with two side panels 104 arranged vertically and fixed on both sides of the middle partition 10, and the side of the side panel 104 facing away from the middle partition 10 is fixedly connected to the charging pile body 100. This design clearly separates the internal space of the charging pile, and the installation and maintenance of the rectifier module 200 are carried out through the first opening 102, while other electronic components and circuits are installed in the maintenance room 30 formed by the side panels 104 and the middle partition 10, and maintained and repaired through the second opening 103. Such a partition design brings many benefits: first, it effectively isolates the rectifier module 200 and other electronic components to avoid mutual interference. For example, when the control circuit or other electronic components need to be repaired, maintenance personnel can directly enter the maintenance room 30 through the second opening 103 without touching or moving the rectifier module 200, thereby reducing the risk of misoperation and improving maintenance efficiency; secondly, the presence of the side panel 104 enhances the structural strength and stability of the maintenance room 30, and provides an installation and support platform for internal electronic components, which makes the internal layout of the maintenance room 30 more regular and easier to dissipate heat.

[0043] In some embodiments, 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.
