Description
Technical Field
[0001] This utility model belongs to the field of power supply devices, and more specifically, it relates to a compatible modular mounting bracket and charging pile. Background Technology
[0002] DC charging piles belong to the field of power equipment. They are the core power distribution, control, and protection units of charging stations (especially DC fast charging stations). The core conventional uses of DC charging piles are: 1) Safe connection to the high-voltage power grid. 2) Efficient conversion of AC power to DC power suitable for vehicle needs. 3) Intelligent power distribution to each charging terminal (gun). 4) Comprehensive protection for the safe operation of the entire charging power. 5) Accurate metering of charging power for billing. 6) Reliable communication connection between the vehicle, charging pile, and the operation backend. 7) Centralized control of the charging process and management of equipment status. 8) Providing protection to ensure stable operation of internal equipment in complex environments. It is the "heart" and "brain" of the entire DC charging station, and its performance and reliability directly determine the operational efficiency and user experience of the charging station.
[0003] Traditional charging station cabinets have front and rear side panels with guide grooves. The charging modules have sliders on their front and rear sides; by inserting these sliders into the guide grooves in the side panels, the charging modules are secured within the cabinet. However, traditional cabinets can only accommodate charging modules of a uniform size. To accommodate charging modules of various sizes, cabinets of different sizes must be designed, significantly increasing costs. Utility Model Content
[0004] The purpose of this utility model is to provide a compatible module mounting rack and charging pile, which aims to overcome the limitation of existing charging piles that can only accommodate charging modules of a single size, thereby effectively reducing costs.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] This utility model provides a compatible module mounting bracket, comprising:
[0007] Four support columns are fixedly installed inside the charging pile cabinet. They are the first support column, the second support column, the third support column, and the fourth support column, which together form the accommodating space. Each support column has several sliding rail fixing holes along the height direction.
[0008] Several limiting slide rails are provided. Some of the limiting slide rails are detachably installed at the slide rail fixing holes of the first support column and the fourth support column, and the other part of the limiting slide rails are detachably installed at the slide rail fixing holes of the second support column and the third support column. This allows the height position of each limiting slide rail on the corresponding two support columns to be adjustable, thereby dividing the accommodating space into module placement areas of various sizes to accommodate charging modules of various sizes.
[0009] Furthermore, the first and second support columns are arranged near the cabinet exhaust door, and the third and fourth support columns are arranged near the cabinet intake door. The placement area of each module corresponds to the fan inside the cabinet.
[0010] Furthermore, each support column has several universal fixing holes along its height direction, and a rear windshield and a front windshield are respectively provided between the two ends of each pair of adjacent module placement areas. Each rear windshield is detachably installed at the universal fixing holes of the first support column and the second support column, and each front windshield is detachably installed at the universal fixing holes of the third support column and the fourth support column.
[0011] Furthermore, a back insert plate is installed at one end of each module placement area, and each back insert plate is detachably installed at a common fixing hole position of the first support column and the second support column.
[0012] Furthermore, each backplate is equipped with a limiting screw that connects to the charging module.
[0013] Furthermore, the other end of each module placement area is used to install the air inlet plate of the charging module, and the air inlet plate of each charging module is detachably installed at the universal fixing hole of the third support column and the fourth support column.
[0014] Furthermore, at least one module placement area is formed by two first limiting slide rails and two second limiting slide rails; the two ends of the two first limiting slide rails are respectively connected to the first support column and the fourth support column, and the slide grooves of the two first limiting slide rails are arranged opposite to each other; the two ends of the two second limiting slide rails are respectively connected to the second support column and the third support column, and the slide grooves of the two second limiting slide rails are arranged opposite to each other.
[0015] Furthermore, the first support column and the fourth support column have the same shape and are arranged symmetrically, and the second support column and the third support column have the same shape and are arranged symmetrically.
[0016] Furthermore, the two ends of the first support column and the second support column are respectively fixed to the air outlet side inside the cabinet via the first mounting top plate and the first mounting bottom plate, and the two ends of the third support column and the fourth support column are respectively fixed to the air inlet side inside the cabinet via the second mounting top plate and the second mounting bottom plate.
[0017] This utility model also provides a charging pile, including a cabinet, multiple charging modules, and a compatible module mounting rack as described above. The module mounting rack is fixedly installed inside the cabinet, and each charging module is inserted into the module placement area of the module mounting rack.
[0018] Compared with existing technologies, the advantages of this utility model's compatible modular mounting rack and charging pile are as follows: In the design of the modular mounting rack, this utility model fully considers the placement requirements of charging modules of different sizes. Each of the four support columns (i.e., the first, second, third, and fourth support columns) is equipped with several slide rail fixing holes. According to actual needs, each limiting slide rail is installed at a certain height fixing hole on two corresponding support columns, meaning the height position of each limiting slide rail on the two corresponding support columns is adjustable. In practical applications, based on the number and size of the charging modules to be placed, an appropriate number of limiting slide rails are selected, and each limiting slide rail is installed at an appropriate height on the two corresponding support columns, thereby dividing the accommodating space into multiple module placement areas corresponding one-to-one with the charging modules. Therefore, the modular mounting rack of this utility model can accommodate various combinations of charging modules of different numbers and sizes, possessing the ability to be compatible with different numbers and sizes of charging modules, significantly reducing costs.

[0034] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0035] Traditional DC charging piles suffer from the following pain points: 1) Poor module compatibility: Traditional cabinets are designed for single charging modules, unable to accommodate multiple charging module configurations or meet the market's demand for higher charging power, lacking flexibility. 2) High cost and inability to mass-produce: Currently, different charging power levels for DC charging piles require two to three cabinet solutions (e.g., 20kW to 160kW power range). Uncertainty in market demand prevents mass production, while small-batch production is costly, and urgent orders have long production cycles and even higher prices, failing to meet market needs. 3) Low assembly efficiency: Different solutions necessitate frequent changes in production plans based on market demands, resulting in low assembly efficiency and an inability to meet rapid expansion requirements. 4) High after-sales costs: DC charging piles require frequent after-sales maintenance. Traditional cabinets require various spare parts of different sizes due to different solutions, leading to long consumption cycles and high costs for these spare parts. 5) High transportation costs: Traditional server racks are designed in different sizes due to different solutions, which leads to different packaging sizes and specifications. Packaging materials cannot be mass-produced, resulting in high costs. If multiple systems are supplied in bulk for a project, the different packaging sizes will make it impossible to consolidate the shipments, requiring multiple vehicles for transportation, which will also lead to high transportation costs.
[0036] Based on this, this utility model achieves multi-power compatibility, rapid batch assembly, and effectively reduces material costs by using standardized and modular design to create a single-size DC charging pile cabinet.
[0037] Please refer to the following: Figures 1 to 6 The compatible module mounting bracket 1 proposed in this utility model includes:
[0038] Four support columns 11 are fixedly installed inside the cabinet 3 of the charging pile. They are the first support column 111, the second support column 112, the third support column 113 and the fourth support column 114 that together form an accommodating space. Each support column 11 has several slide rail fixing holes 1101 along the height direction.
[0039] Several limiting slide rails 12 are provided. Some of the limiting slide rails 12 are detachably installed at the slide rail fixing holes 1101 of the first support column 111 and the fourth support column 114, and the other part of the limiting slide rails 12 are detachably installed at the slide rail fixing holes 1101 of the second support column 112 and the third support column 113. This allows the height position of each limiting slide rail 12 on the corresponding two support columns 11 to be adjustable, thereby dividing the accommodating space into module placement areas 13 of various sizes to be compatible with charging modules 2 of various sizes.
[0040] In the design of the module mounting rack 1, this utility model fully considers the placement requirements of charging modules 2 of different sizes. Each of the four support columns 11 (i.e., the first support column 111, the second support column 112, the third support column 113, and the fourth support column 114) is provided with several slide rail fixing holes 1101. According to actual needs, each limiting slide rail 12 is installed at a certain height of the slide rail fixing hole 1101 on two corresponding support columns 11, meaning the height position of each limiting slide rail 12 on the two corresponding support columns 11 is adjustable. In practical applications, based on the number and size of the charging modules 2 to be placed, an appropriate number of limiting slide rails 12 are selected, and each limiting slide rail 12 is installed at an appropriate height position on the two corresponding support columns 11, thereby dividing the accommodating space into multiple module placement areas 13 corresponding one-to-one with the charging modules 2. Therefore, the module mounting rack 1 of this utility model can accommodate combinations of various numbers and sizes of charging modules 2, possessing the ability to be compatible with different numbers and sizes of charging modules 2, significantly reducing costs.
[0041] For ease of understanding, several optional embodiments are described below. In these embodiments, the charging module 2 comes in two sizes, the main difference being its height. Each size of the charging module 2 corresponds to a different charging power: the taller charging module 2 has a charging power of 40kW, while the shorter charging module 2 has a charging power of 30kW.
[0042] like Figure 3 As shown, in a first optional embodiment, four charging modules 2 with a charging power of 40kW are placed inside the module mounting rack 1. The module mounting rack 1 can accommodate one to four charging modules 2 with a charging power of 40kW.
[0043] like Figure 4 As shown, in the second optional embodiment, three charging modules 2 with a charging power of 30kW are placed inside the module mounting rack 1. The module mounting rack 1 can accommodate one to four charging modules 2 with a charging power of 30kW.
[0044] In a third optional embodiment, a charging module 2 with a charging power of 40kW and a charging module 2 with a charging power of 30kW are placed inside the module mounting bracket 1.
[0045] Therefore, this utility model can flexibly install the limiting slide rail 12 according to the user's actual needs, so that the same module mounting frame 1 can accommodate a variety of charging modules 2 of different quantities and sizes. This design realizes that the overall charging power of a single-size charging pile can be adjusted from 20 to 160kW, greatly expanding its adaptability and significantly reducing costs.
[0046] Meanwhile, compared with the traditional charging pile cabinet 3 with its internal front and rear side panel design, the modular mounting frame 1 of this utility model adopts a lightweight sheet metal structure, which not only effectively reduces the cost of sheet metal materials, but also meets the compatibility requirements of various charging power.
[0047] like Figure 1 , Figure 2 As shown, of the four support columns 11, the first support column 111 and the second support column 112 are arranged near the cabinet exhaust door 31, and the third support column 113 and the fourth support column 114 are arranged near the cabinet intake door 32. Each module placement area 13 is correspondingly set with the fan inside the cabinet 3. With this design, the present invention can effectively improve the heat dissipation efficiency of the charging module 2.
[0048] In addition, each support column 11 has several universal fixing holes 1102 along the height direction.
[0049] like Figure 5 , Figure 6 As shown, a rear baffle 161 and a front baffle 162 are respectively provided between the two ends of each pair of adjacent module placement areas 13. Each rear baffle 161 is detachably installed at the universal fixing hole 1102 of the first support column 111 and the second support column 112, and each front baffle 162 is detachably installed at the universal fixing hole 1102 of the third support column 113 and the fourth support column 114. With this design, the present invention can ensure that the height of each module placement area 13 is precisely aligned with the fan inside the cabinet 3, while further improving the heat dissipation efficiency of the charging module 2. It should also be understood that the front baffle 162 and the rear baffle 161 are available in various height specifications to accommodate charging modules 2 of various sizes.
[0050] like Figure 5 As shown, a backplate 15 is installed at one end of each module placement area 13. Each backplate 15 is detachably installed at the universal fixing hole 1102 of the first support post 111 and the second support post 112. The backplate 15 supports plug-and-play AC / DC modules, simplifying the installation process. It should also be understood that the backplate 15 is available in various sizes to accommodate charging modules 2 of different dimensions.
[0051] Each backplate 15 is equipped with a limiting screw that connects to the charging module 2. This design securely connects the backplate 15 to the charging module 2 using the limiting screw, thereby reducing the risk of damage to the internal charging module 2 during transportation.
[0052] like Figure 6As shown, the other end of each module placement area 13 is used to install the air inlet plate 21 of the charging module 2. The air inlet plate 21 of each charging module 2 is detachably installed at the universal fixing hole 1102 of the third support column 113 and the fourth support column 114. With this design, the air inlet plate 21 of the charging module 2 is fixedly connected to the two support columns 11 by fasteners, thereby reducing the risk of damage to the internal charging module 2 of the charging pile during transportation.
[0053] like Figure 3 As shown, at least one module placement area 13 is formed by two first limiting slide rails 121 and two second limiting slide rails 122. The two ends of the two first limiting slide rails 121 are respectively connected to a first support column 111 and a fourth support column 114, and the grooves 123 of the two first limiting slide rails 121 are arranged opposite to each other. The two ends of the two second limiting slide rails 122 are respectively connected to a second support column 112 and a third support column 113, and the grooves 123 of the two second limiting slide rails 122 are arranged opposite to each other. With this design, the present invention uses the upper and lower first limiting slide rails 121 and the upper and lower second limiting slide rails 122 to limit the upper and lower movement of the charging module 2, thereby effectively reducing the risk of damage to the internal charging module 2 during transportation of the charging pile.
[0054] It should be understood that in other alternative embodiments, each module placement area 13 may have only one first limiting slide rail 121 and one second limiting slide rail 122.
[0055] It should be noted that the charging module 2 of the traditional cabinet 3 is at risk of damage during transportation after assembly. Therefore, the cabinet 3 and the charging module 2 are usually transported separately. This not only increases transportation costs but also raises maintenance and debugging costs, and is inconvenient to operate. In a more preferable way, this utility model uses four limiting slide rails 12 for upper and lower limits, limiting screws on the back plate 15 for limiting, and screws to lock the air inlet plate 21 of the charging module 2 to the support column 11. These three methods together meet the assembly and transportation requirements of the charging module 2, significantly reducing the transportation cost and maintenance and debugging cost of the cabinet 3.
[0056] like Figures 3 to 6 As shown, the first support column 111 and the fourth support column 114 are identical in shape and symmetrically arranged, as are the second support column 112 and the third support column 113. This symmetrical layout enhances the balance and stability of the module mounting frame 1, reducing the shaking of the charging module 2 within the mounting frame 1, thus ensuring good stability and safety of the charging pile during transportation and use.
[0057] like Figure 2As shown, the two ends of the first support column 111 and the second support column 112 are respectively fixed to the air outlet side inside the cabinet 3 via the first mounting top plate 171 and the first mounting bottom plate 172. The two ends of the third support column 113 and the fourth support column 114 are respectively fixed to the air inlet side inside the cabinet 3 via the second mounting top plate 173 and the second mounting bottom plate 174. With this design, the present invention uses multiple mounting top plates and mounting bottom plates to firmly fix the four support columns 11 inside the cabinet 3, ensuring the stability and reliability of the module mounting frame 1, effectively reducing the shaking of the module mounting frame 1 and its internal charging module 2, thereby ensuring good stability and safety of the charging pile during transportation and use.
[0058] The charging pile proposed in this utility model includes a cabinet 3, multiple charging modules 2, and a compatible module mounting frame 1. The module mounting frame 1 is fixedly installed inside the cabinet 3, and each charging module 2 is inserted into the module placement area 13 of the module mounting frame 1. The structure of the module mounting frame 1 is detailed above and will not be repeated here.
[0059] This utility model charging pile adopts a "one cabinet, multiple power" compatible design, allowing a single cabinet to accommodate charging modules of different sizes, effectively meeting the diverse needs of market systems and covering a power range of 20-160kW. The lightweight sheet metal design, validated by engineering mechanics, reduces material costs by approximately 32.4% compared to traditional cabinets. The multi-power compatible design eliminates the need for customization to specific market demands, enabling mass production and supporting assembly line operations, significantly shortening the delivery cycle. The production department can pre-assemble the sheet metal cabinet, DC output, and secondary sampling devices, and then configure the corresponding charging modules and modular backplanes according to actual market needs to complete subsequent processes. The charging modules are assembled in the cabinet before transportation, reducing the time from order placement to delivery to approximately 5 days, thus shortening the delivery time by about 20 days.
[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
