[0032] Please refer to Figs. 1-3In an embodiment, the copper bar assembly further comprises a bottom plate 42, and the half-matrix components 41 are arranged in a triangular structure, and two half-matrix components 41 are arranged in a rectangular structure on the bottom plate 42. The copper bar assembly is designed to include a bottom plate 42, and the half-matrix components 41 are arranged in a triangular structure, and the two half-matrix components 41 are arranged in a rectangular structure on the bottom plate 42. The triangular structure of the half-matrix components 41 can make more efficient use of internal space, especially when arranging complex electrical connections in limited space. Such a design helps to reduce the volume of the entire device, making it more compact and suitable for installation in limited space, such as inside a charging pile. The triangular structure of the half-matrix components 41 has good resistance to deformation. Therefore, the half-matrix components 41 arranged in a triangular structure can maintain structural stability when subjected to large currents or external impact forces, reducing the risk of failure due to mechanical stress. The overall rectangular layout facilitates standardized production and simplifies the assembly process. At the same time, when maintenance or replacement of components is required, the rectangular layout makes the positions of the various components more intuitive, allowing operators to quickly locate and handle problems.

[0033] Referring to Figs. 1-3In an embodiment, each half-matrix component 41 includes a connection sub-component 412, each connection sub-component 412 includes a bridge copper bar 412a and a plurality of extension copper bars 412b, the number of extension copper bars 412b in each connection sub-component 412 is equal to the row number it belongs to, the plurality of extension copper bars 412b are arranged along the length direction of the bridge copper bar 412a, two connection sub-components 412 are arranged along the direction perpendicular to the length direction of the bridge copper bar 412a, the current guide copper bar 411 is installed on the extension copper bar 412b, the number of positive copper bars 1 and the number of negative copper bars 2 are equal to the number of charging guns of the charging pile, and the difference between the number of connection sub-components 412 and the number of charging guns of the charging pile is 1. The number of positive copper bars 1 and the number of negative copper bars 2 are equal to the number of charging guns of the charging pile, which means that each charging gun has independent positive and negative copper bars 2 connections, and can provide charging services for multiple vehicles at the same time without affecting each other. The number of connection sub-components 412 is one less than the number of charging guns, which allows the system to be easily adjusted to accommodate different numbers of charging guns by adding or removing connection sub-components 412. This not only increases the flexibility of the system, but also makes future expansion simple. Each connection sub-component 412 includes a bridge copper bar 412a and a plurality of extension copper bars 412b, and the number of extension copper bars 412b is equal to the row number it belongs to. This design ensures that the current can be evenly distributed through multiple paths, reducing the current density on a single path, thereby reducing heat and loss and improving overall efficiency. The plurality of extension copper bars 412b are arranged along the length direction of the bridge copper bar 412a, and two connection sub-components 412 are arranged along the direction perpendicular to the bridge copper bar 412a. This layout can achieve efficient current transmission in a limited space while ensuring good mechanical stability and heat dissipation performance. Since each charging gun corresponds to a set of independent positive and negative copper bars 2 and corresponding connection sub-components 412, when a problem occurs in a certain charging channel, targeted maintenance or replacement can be performed without affecting the normal operation of other charging channels. In addition, the modular design of the connection sub-component 412 also makes replacement and upgrading easier.

[0034] Please refer to Figs. 1-3In an embodiment, the number of the drain copper bars 411 and the number of the extension copper bars 412b in each connection sub-component 412 are equal and correspond to each other. Each drain copper bar 411 corresponds to one extension copper bar 412b, ensuring that the current can be directly transmitted from the power module to the corresponding extension copper bar 412b through the bridging copper bar 412a, and then transmitted from the extension copper bar 412b to the corresponding drain copper bar 411. This direct current path reduces the detours and losses in current transmission, improving transmission efficiency. Since each drain copper bar 411 has a corresponding extension copper bar 412b, the current can be evenly distributed to each path, avoiding the problem of current overload on some paths. This not only improves the overall efficiency of the system, but also prolongs the service life of the copper bars and related components.

[0035] Please refer to Figs. 1-3 In an embodiment, each bridging copper bar 412a in each half-matrix component 41 has a bus copper bar 412c at one end facing the other half-matrix component 41, and the bus copper bar 412c is connected to the positive copper bar 1. The number of connection sub-components 412, positive copper bars 1 and negative copper bars 2 is determined according to the number of charging guns. Taking nine charging guns as an example, there will be nine pairs of positive and negative copper bars 2, of which nine positive copper bars 1 are installed on one half-matrix component 41, and the other nine negative copper bars 2 are installed on the other half-matrix component 41. The positive copper bars 1 and the negative copper bars 2 are arranged alternately, and the positive copper bars 1 are connected to the bus copper bars 412c. In this way, when the current is transmitted to the positive copper bars 1, the current will be transmitted to the bridging copper bars 412a on the eight connection sub-components 412 through the bus copper bars 412c, and then to the drain copper bars 411. This allows each charging gun to evenly distribute the current output by the power component, avoiding uneven charging power, and achieving orderly dynamic distribution of current.

[0036] Please refer to Figs. 1-3 In an embodiment, one positive copper bar 1 and one negative copper bar 2 are installed on the bottom plate 42 and arranged on the two sides of the half-matrix component 41, respectively. By arranging the positive and negative copper bars 2 on the two sides of the half-matrix component 41, a more reasonable layout can be achieved in a limited space. This design makes full use of the area of the bottom plate 42, making the entire device more compact and suitable for installation inside the charging pile with limited space. The symmetrical arrangement of the copper bars on both sides not only looks good, but also facilitates standardized production and assembly, improving production efficiency.

[0037] Please refer to Figs. 1-3In an embodiment, the bottom plate 42 is provided with a plurality of first raised blocks 5 on both sides along the length direction of the vertical bridging copper bars 412a, and the plurality of first raised blocks 5 respectively abut against one of the positive copper bars 1 and one of the negative copper bars 2. The first raised blocks 5 provide additional support points for the positive and negative copper bars 2, making the copper bars more stable when subjected to current or external impact, reducing the risk of deformation and displacement. Especially during high-current transmission, the copper bars may be slightly deformed due to thermal expansion or mechanical stress, and the raised blocks can effectively prevent this. The plurality of raised blocks are spaced along the length direction of the copper bars, ensuring uniform distribution of load and avoiding local stress concentration, prolonging the service life of the copper bars.

[0038] Please refer to Figs. 1-3 In an embodiment, the odd-numbered row of connecting sub-components 412 in the half-matrix component 41 connected to the positive copper bars 1 further includes a plurality of second raised blocks 413 equal in number to the number of extended copper bars 412b, and the second raised blocks 413 are staggered with the extended copper bars 412b, and the plurality of second raised blocks abut against the negative copper bars 2. The second raised blocks 413 provide additional support points for the extended copper bars 412b in the half-matrix component 41, especially in the odd-numbered row of connecting sub-components 412, which can effectively prevent the extended copper bars 412b from deforming or displacing when subjected to current or external impact. The plurality of support points are uniformly distributed, ensuring balanced load and enhancing the mechanical stability of the entire system. The presence of the second raised blocks 413 can absorb and disperse vibration energy to some extent, reducing the resonance of the copper bars due to external vibration or impact, especially in the case of charging piles that may be subjected to environmental vibration, which helps to improve the long-term reliability of the system. The second raised blocks 413 slightly lift the extended copper bars 412b away from the bottom plate 42, increasing the air gap between the copper bars and the bottom plate 42, promoting air circulation and helping heat to dissipate more quickly. This is particularly important for high-current transmission, effectively reducing the temperature of the copper bars and reducing the risk of failure due to overheating.

[0039] Please refer to Figs. 1-3 Figs. 1-3In an embodiment, the connection sub-components 412 of the even-numbered rows in the half-matrix component 41 connected to the negative copper bar 2 further comprise a third number of spacer blocks 414 equal to the number of the extended copper bars 412b, the third spacer blocks 414 are staggered with the extended copper bars 412b, and the plurality of third spacer blocks abut the positive copper bar 1. The third spacer blocks 414 provide additional support points for the extended copper bars 412b of the other half-matrix component 41, especially in the connection sub-components 412 of the odd-numbered rows, this design can effectively prevent the extended copper bars 412b from deforming or displacing when subjected to current or external impact. The uniform distribution of the plurality of support points ensures the balance of the load and enhances the mechanical stability of the entire system. The presence of the third spacer blocks 414 can absorb and disperse vibration energy to some extent, reducing the resonance of the copper bars due to external vibration or impact, especially in the case of charging piles that may be subjected to environmental vibration, which helps to improve the long-term reliability of the system. The third spacer blocks 414 slightly lift the extended copper bars 412b away from the bottom plate 42, increasing the air gap between the copper bars and the bottom plate 42, promoting air circulation, and helping to dissipate heat more quickly. This is particularly important for high-current transmission, which can effectively reduce the temperature of the copper bars and reduce the risk of failure due to overheating.

Since the charging pile includes all the embodiments of the charging gun described above, it has at least all the beneficial effects of all the embodiments described above, which will not be repeated here.

[0041] The above is only an exemplary embodiment of the utility model, and does not limit the patent scope of the utility model, any equivalent structural transformation made by the utility model specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the utility model.
