Description

Technical Field

[0001] This utility model relates to the field of charging station design technology, and in particular to a charging station. Background Technology

[0002] Charging stations have emerged alongside the development of the electric vehicle and new energy industry.

[0003] Existing charging stations, such as those disclosed in the invention patent with patent number CN104734262B entitled "A Charging Station", include a base; a power distribution unit detachably mounted on the base; a charging unit detachably mounted on the base, wherein the power distribution unit is electrically connected to the charging unit and supplies power to the charging unit; and a monitoring unit detachably mounted on the base and electrically connected to the power distribution unit and the charging unit to detect the operating parameters of the power distribution unit and the charging unit.

[0004] Similar to the charging stations described above, traditional charging stations often use linear busbars or evenly distributed conductor structures at their power output ends, resulting in high-power interfaces and low-power interfaces sharing the same conductor specifications. This design forces large currents to pass through multiple tap points, causing current path redundancy. Furthermore, existing solutions often use enclosed installations for power distribution conductors, requiring the removal of multiple layers of structural components to reach critical connection points during maintenance. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a charging station that solves the problems of long current distribution paths and poor maintenance convenience in traditional charging stations.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A charging station includes a cabinet frame with a top cap and a base. A front door and a back door are hinged to opposite sides of the cabinet frame. A mounting frame is fixed inside the cabinet frame. Two sets of power modules are detachably installed inside the mounting frame. A mounting plate is fixed inside the cabinet frame and below the mounting frame. Matrix transmission components are provided on both sides of the mounting plate facing the front door and the back door. The matrix transmission components on both sides of the mounting plate correspond to the two sets of power modules respectively. The matrix transmission components are used to distribute the output current of the power modules.

[0008] The present invention is further configured such that each power module group consists of several power modules.

[0009] The present invention is further configured such that: the matrix transmission component includes several vertically arranged first guides and several horizontally arranged second guides, the first guides and the second guides are perpendicularly intersected and fixed to form a grid structure, and all the second guides are distributed in a stepped manner from top to bottom, wherein the length of the second guides located at the bottom is greater than that of the second guides located at the top, so that the number of first guides connected to each second guide increases step by step from top to bottom.

[0010] The present invention is further configured such that: each of the second guide bars is provided with a plurality of connection holes, and the plurality of connection holes are distributed along the length direction of the second guide bars to adapt to the installation position of contactors with different power.

[0011] The present invention is further configured such that: the mounting plate has an insulating layer on both sides facing the front door and the back door.

[0012] The present invention is further configured such that: the cabinet frame is hinged to the other two sides with side doors, and the mounting bracket is fixed to the side wall facing the two side doors with a wire guide frame, and each wire guide frame is equipped with a main valve switch.

[0013] The present invention is further configured such that: a heat dissipation hole is provided on the back door, and a heat dissipation fan is provided inside the heat dissipation hole.

[0014] Compared to the beneficial effects achieved by existing technologies:

[0015] By employing a hierarchical layout of mounting racks and plates within the cabinet frame, combined with symmetrically arranged matrix transmission components, a synergistic optimization of current distribution efficiency and equipment maintainability is achieved. Two detachable power modules within the mounting rack independently correspond to the matrix transmission components on either side of the mounting plate, forming a dual-system parallel architecture. When a single power module fails, it can be independently disassembled for maintenance, avoiding system downtime. The design of the mounting plate, positioned below the power modules and with matrix transmission components evenly distributed on both sides, vertically shortens the current distribution path, reducing transmission losses. The layout of the matrix transmission components directly facing the front and rear doors, along with the hinged structure of the cabinet doors, allows operators to directly access the current distribution units from both the front and rear, achieving zero-blind-zone operation for cable connection / maintenance and improving maintenance efficiency.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] Example:

[0024] Reference Figures 1-5 This application discloses a charging station, comprising a cabinet frame 1 with a top cap and a base. A front door 2 and a back door 3 are hinged to opposite sides of the cabinet frame 1. A mounting frame 4 is fixed inside the cabinet frame 1, and two sets of power modules are detachably mounted within the mounting frame 4. Each power module set consists of several power modules 7. In this application, each power module set has 12 power modules 7, each power module 7 providing a power output of 40kW. Each power module 7 is bolted to the mounting frame 4. Figure 1 and Figure 5 As shown, a heat dissipation hole 14 is provided on the back door 3, and a heat dissipation fan 15 is provided inside the heat dissipation hole 14. The heat dissipation fan 15 can effectively dissipate heat inside the cabinet frame 1.

[0025] like Figure 2 As shown, a mounting plate 5 is fixed inside the cabinet frame 1 and below the mounting bracket 4. Matrix transmission components are provided on both sides of the mounting plate 5 facing the front door 2 and the back door 3. Each matrix transmission component on either side of the mounting plate 5 corresponds to one of the two power modules, and the matrix transmission components are used to distribute the output current of the power modules. For example... Figure 2 and Figure 3As shown, the matrix transmission component includes several vertically arranged first guide rails 8 and several horizontally arranged second guide rails 9. The first guide rails 8 and second guide rails 9 are perpendicularly intersected and fixed to form a grid structure, and all second guide rails 9 are distributed in a stepped manner from top to bottom. The length of the second guide rails 9 located at the bottom is greater than that of the second guide rails 9 located at the top, so that the number of first guide rails 8 connected to each second guide rail 9 increases progressively from top to bottom. Several connecting holes 10 are respectively opened on several second guide rails 9, and the connecting holes 10 are distributed along the length direction of the second guide rails 9 to adapt to the installation position of contactors with different power. This contactor is the same as the contactor disclosed in the prior art invention patent with publication number CN117962655A entitled "A Full Matrix Miniaturized Integrated Charging Station".

[0026] like Figure 4 As shown, the mounting plate 5 has an insulating layer 11 on both sides facing the front door 2 and the back door 3. The insulating layer 11 can be epoxy resin.

[0027] The cabinet frame 1 is hinged to two other sides with side doors 12. The mounting bracket 4 has cable trays 13 fixed to its side walls facing the two side doors 12. Each cable tray 13 corresponds to one of the two power modules. Side cable routing makes wiring clearer and easier for installation and subsequent maintenance. Each cable tray 13 has a main valve switch 6. This application also includes output control devices such as the power distribution control system described in the aforementioned patent with publication number CN117962655A. The structure and installation of such devices are prior art and will not be elaborated upon here.

[0028] Working principle:

[0029] During operation, the two power modules work together to provide a total power output of up to 960kW. The DC power generated by power module 7 is first fed into the corresponding matrix transmission component for intelligent distribution. This matrix transmission component consists of a unique grid structure formed by vertically intersecting first guide rails 8 and second guide rails 9, both of which are copper busbars. The second guide rails 9 are arranged in a stepped manner from top to bottom, allowing each lower second guide rail 9 to connect to more first guide rails 8. This layout, combined with multiple sets of connection holes 10 distributed along the length of the second guide rails 9, provides a highly flexible installation interface for power contactors of different specifications and installation positions. The power distribution control system can accurately and dynamically distribute electrical energy to different charging terminals by controlling the on / off state of the contactors installed on the matrix transmission component. At the same time, the cooling fan 15 on the back door 3 works continuously, forming a forced airflow through the cooling holes 14, effectively removing the heat generated by the power modules and electrical components inside the cabinet, ensuring the stability of the system under long-term high-load operation. The wiring racks 13 installed at the side doors 12 centrally manage the wires and cables between electrical components, making the wiring clear and maintenance convenient.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
