[0002] With the development of new energy technologies, more and more electric vehicles need to be charged at charging stations. However, to meet the security requirements of charging stations, traditional charging stations typically require digging into the ground to bury cables and installing drainage, ventilation, and rodent-proof facilities. Furthermore, to prevent damage during wiring, each cabinet needs to be directly connected to the mains power supply via cables to ensure waterproofing meets usage requirements. This complex installation structure makes it difficult to deploy charging stations quickly. Moreover, since each cabinet needs to be individually connected to the mains power supply via cables, it consumes a large amount of wiring. Therefore, existing technologies cannot provide a fast and cost-effective way to install and deploy charging stations. Utility Model Content

[0025] In this embodiment, as Figure 1 and Figure 2As shown, this utility model embodiment provides an integrated power busbar base for charging stations. The integrated power busbar base includes a rectangular shell 1, a busbar 2, a heat dissipation and ventilation guide plate 3, and a support 4; the rectangular shell 1 has a hollow cavity inside. For detailed structure, please refer to [reference needed]. Figure 3 and Figure 5 The heat dissipation and ventilation guide plates 3 are all mounted on the top surface of the hollow cavity; the busbar 2 is composed of multiple parallel wires, all of which are arranged along the long side of the rectangular shell 1, with gaps between adjacent wires; the bottom surface of the busbar 2 is provided with multiple insulating supports 21, and a fixed support 22 is provided between the bottom of the insulating support 21 and the bottom surface of the hollow cavity; the support 4 is fixedly installed on the lower end face of the rectangular shell 1; at least one hollow through hole is opened on the upper end face of the rectangular shell 1, and the cabinet 5 is installed above the rectangular shell 1 and covers the hollow through hole; multiple circuit breakers 23 are spaced above the busbar 2, and each circuit breaker 23 is electrically connected to the busbar 2 through a connecting cable 24, which passes through the hollow through hole.

[0026] The upper surface of the rectangular housing 1 serves as the equipment support surface for mounting various cabinets 5. The hollow cavity of the rectangular housing 1 can be used to install the busbar 2 and the heat dissipation and ventilation guide plate 3. Since the busbar 2 is set inside the rectangular housing 1 as the common connection point for all circuit breakers 23, the amount of cable used is significantly reduced while ensuring waterproofing meets usage requirements. Each cabinet 5 does not need to be individually connected to the mains power supply via cable, saving cable costs. The busbar 2 and heat dissipation and ventilation guide plate 3 are installed inside the hollow cavity, thereby guiding the internal airflow through the heat dissipation and ventilation guide plate 3, improving heat dissipation performance and meeting the application requirements of heat dissipation and rodent prevention. Furthermore, due to the small overall size of the rectangular housing 1, the integrated power busbar base integrates the functional components into a single base, facilitating the overall relocation of the cabinets 5 above it. Therefore, it features safety, environmental friendliness, small footprint, and ease of relocation. For convenient transportation, the dimensions of the rectangular housing 1 can be set to correspond to the container dimensions, that is, the dimensions of the rectangular housing 1 can be set to be equal to the length and width of the container.

[0027] Busbar 2 is secured using a combination of fixed bracket 22 and insulating bracket 21, making it more stable and preventing short circuits in the copper busbars during circuit breaks. This ensures the dynamic and thermal stability of the busbar 2 meets the short-circuit current requirements. While conventional electrical equipment is connected by cables, this solution replaces the cable connection with the busbar 2 connection. This reduces installation difficulty, improves electrical connection reliability, and enhances equipment operational safety.

[0028] In a more specific embodiment, the busbar 2 is a soft copper busbar 2. Specifically, each conductor in the busbar 2 consists of a copper wire conductor, a wrapping layer, an insulation layer, a metal armor layer, and a sheath layer; the wrapping layer is disposed around the outer wall of the copper wire conductor, the insulation layer is disposed around the outer wall of the wrapping layer, the metal armor layer is disposed around the outer wall of the insulation layer, and the sheath layer is disposed around the outer wall of the metal armor layer.

[0029] Specifically, such as Figure 5 As shown, busbar 2 can be configured as a soft copper busbar 2, in which case each conductor in busbar 2 relies on soft copper wire as the conductor for electrical conductivity. Each conductor is composed of a copper wire conductor, a wrapping layer, an insulation layer, a metal armor layer, and a sheath layer, thus ensuring that each conductor meets the requirements for insulation and safe use. The connecting cable 24 from circuit breaker 23 forms a "T" connection with the conductors in busbar 2. The joint of the "T" connection is reinforced with insulation to prevent backflow during heavy rain or storms from affecting the circuit connection performance. A certain gap is provided between the parallel conductors in busbar 2 to improve the safety of busbar 2 in use.

[0030] In a more specific embodiment, the heat dissipation and ventilation guide plates 3 all have an L-shaped cross-section, and the heat dissipation and ventilation guide plates 3 are arranged radially around the midpoint of the rectangular shell 1. The lower end face of the rectangular shell 1 has multiple mounting holes communicating with the hollow cavity, and each mounting hole is fitted with a ventilation and heat dissipation plate 11. The ventilation and heat dissipation plate 11 has multiple heat dissipation holes 111 arranged in a matrix. The upper end face of the rectangular shell 1 has multiple ventilation columns 12 communicating with the hollow cavity; the end of each ventilation column 12 not connected to the rectangular shell 1 opens towards one side of the rectangular shell 1. Furthermore, the end of each ventilation column 12 not connected to the rectangular shell 1 has a filter plate; the filter plate has filter holes.

[0031] Specifically, the cross-section of the heat dissipation and ventilation guide plate 3 can be L-shaped. After the heat dissipation and ventilation guide plate 3 is fixed to the bottom surface of the hollow cavity, a long strip-shaped baffle extends downward. The heat dissipation and ventilation guide plates 3 are arranged radially around the midpoint of the rectangular shell 1, as shown in the specific structure. Figure 3 As shown, the long strip-shaped baffles extending downwards from each heat dissipation and ventilation wing guide plate 3 are used to guide the airflow so that the heat accumulated in the central area can be diffused to the surrounding areas.

[0032] Furthermore, a mounting through hole can be provided on the lower end face of the rectangular shell 1, and a ventilation and heat dissipation plate 11 can be fixedly mounted on the mounting through hole. The external structure of the ventilation and heat dissipation plate 11 is as follows: Figure 6As shown, the ventilation and heat dissipation plate 11 has multiple heat dissipation holes 111 arranged in a matrix. The cold air at the bottom of the rectangular housing 1 can pass through the ventilation and heat dissipation plate 11 and enter the hollow cavity. Under the rising action of the hot air in the cabinet 5, the airflow is driven upwards and heat dissipation is achieved. Part of the airflow, while moving upwards, is guided by the heat dissipation and ventilation guide plates 3 in the hollow cavity and moves outwards. The specific gas flow direction is as follows... Figure 4 As shown. To prevent animals such as rats and cockroaches from crawling into the hollow cavity, the diameter of the heat dissipation through hole 111 can be 0.2-2mm; preferably, the diameter of the heat dissipation through hole 111 is 0.2-1mm.

[0033] Furthermore, such as Figure 4 As shown, a ventilation column 12 can be installed on the upper surface of the rectangular housing 1. The ventilation column 12 can be installed on the outside of the cabinet 5, so that part of the airflow guided by the heat dissipation ventilation guide plate 3 and moving outward can be discharged outward through the ventilation column 12. To make the ventilation column 12 waterproof, the end opening of the ventilation column 12 can be set to face the side of the rectangular housing 1. Furthermore, to prevent animals such as rats and cockroaches from crawling into the hollow cavity, a filter plate can be installed at the end opening of the ventilation column 12. The filter plate is provided with filter holes, and the diameter of the filter holes can be set to 0.2-2mm; preferably, the diameter of the filter holes is 0.2-1mm.

[0034] In a more specific embodiment, the support 4 includes a corner support 41 and a transverse support 42; each corner support 41 is disposed at the corner of the rectangular housing 1; the transverse support 42 is disposed in the middle of the rectangular housing 1 and is perpendicular to the long side of the rectangular housing 1. At least one fan is provided inside the hollow cavity, and the fan blows air from bottom to top.

[0035] To improve the supporting effect of support 4 on the rectangular shell, support 4 can be configured to consist of a corner support 41 and a transverse support 42. For example... Figure 2 As shown, four corner supports 41 can be fixedly mounted at the four corners of the rectangular shell 1; at the same time, a transverse support 42 is provided in the middle of the rectangular shell 1 and perpendicular to the long side of the rectangular shell 1. To further improve the heat dissipation performance inside the hollow cavity, one or more fans can be installed inside the hollow cavity, wherein the airflow direction of the fans is from bottom to top.

[0036] This utility model embodiment also provides a charging station, wherein the charging station includes a charging gun, a cabinet 5, and an integrated power busbar base for the charging station as described in the above embodiment; the cabinet 5 is disposed above the rectangular shell 1 and covers the hollow through hole; the electrical components inside the cabinet 5 are electrically connected to the circuit breaker 23; the cabinet 5 includes a communication cabinet 5, an energy storage cabinet, a power distribution cabinet, an AC / DC conversion cabinet, and a power stack cabinet; the charging gun is electrically connected to the power distribution cabinet. The side panel of the cabinet 5 is provided with heat dissipation holes; the heat dissipation holes are arranged in a matrix on the side panel of the cabinet 5; an arc-shaped baffle 51 is provided above each heat dissipation hole, and the outer edge of the arc-shaped baffle 51 is inclined downwards.

[0037] A charging station can be constructed based on the aforementioned integrated power busbar base. The cabinet 5 is mounted on the integrated power busbar base, and the charging gun is installed in the distribution cabinet and electrically connected, resulting in a complete charging station structure. The charging station can then be transported to a designated location and connected to mains power for rapid deployment. Figure 7 As shown, in order to further improve the heat dissipation performance of the charging station, heat dissipation holes can be set on the side panel of the cabinet 5, and an arc-shaped baffle 51 is set above each heat dissipation hole to prevent rainwater from entering the cabinet 5 and improve the waterproof performance.

[0038] Skid-mounted charging stations refer to integrated structures where functional components are integrated onto a single base, allowing for complete installation and relocation. The aforementioned skid-mounted charging stations are manufactured, assembled, and commissioned entirely in the factory. After the cabinet 5 is installed and electrical connections and testing are completed at the factory, it can be directly deployed to the charging station site, minimizing on-site installation work; only the power supply and grounding connections need to be completed. Because the functional components are integrated into a single base, the system can be easily moved as a whole. Furthermore, the aforementioned skid-mounted charging station equipment has a compact structure, reducing the floor space required compared to traditional installation methods, and is characterized by its compact structure and small footprint.

[0039] This utility model provides an integrated power busbar base and a charging station for charging stations. The integrated power busbar base includes a rectangular shell 1, a busbar 2, heat dissipation and ventilation guide plates 3, and a support 4. The rectangular shell 1 has a hollow cavity inside. The heat dissipation and ventilation guide plates 3 are all mounted on the top surface of the hollow cavity. The busbar 2 is composed of multiple parallel wires, all of which are arranged along the long side of the rectangular shell 1, with gaps between adjacent wires. The bottom surface of the busbar 2 is provided with multiple insulating supports 21, and a fixed support 22 is provided between the bottom of the insulating support 21 and the bottom surface of the hollow cavity. The support 4 is fixedly installed on the lower end surface of the rectangular shell 1. The aforementioned integrated power busbar base adopts a skid-mounted structure based on a modular base plate. After the cabinet 5 is installed in the factory and electrical connections and debugging are performed, it can be directly deployed on the charging station site. It features fireproof and explosion-proof properties, safety and environmental protection, small footprint and easy relocation, which greatly improves the flexibility and efficiency of charging station deployment and achieves the application effect of fast and low-cost installation and deployment of charging stations.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
