[0041] Generally, the charging pile 100 includes a plurality of electrical connection ports 10, and electrical connection is required between the corresponding electrical connection ports 10. With the above structure, the laminated copper busbar 20 is formed by stacking a plurality of sub-copper busbars 22, and thus the whole laminated copper busbar 20 is rigid; during the installation process of the laminated copper busbar 20, the laminated copper busbar 20 can be first fixed at the pre-installed position, so that each electrical transfer port 222 is close to or in contact with the corresponding electrical connection port 10, that is, each electrical transfer port 222 is relatively fixed to a corresponding electrical connection port 10, and then each electrical transfer port 222 is electrically connected to a corresponding electrical connection port 10; thus, the installation process of the laminated copper busbar 20 is more convenient, and the assembly process of the whole charging pile 100 is simplified.

[0042] In addition, the sub-copper busbar 22 is made of copper and has a larger cross-sectional area, so that the sub-copper busbar 22 has a smaller resistance, so that the heat generated at the sub-copper busbar 22 during the operation of the charging pile 100 is smaller, the whole laminated copper busbar 20 is more conducive to heat dissipation, and the electrothermal power of the sub-copper busbar 22 is smaller. Under the action of the insulating layer 24, two adjacent sub-copper busbars 22 in the same laminated copper busbar 20 are separated from each other and will not be short-circuited due to mutual electrical connection.

One sub-copper busbar 22 can also include other numbers of electrical transfer ports 222, such as three or four. The electrical connection port 10 and the electrical transfer port 222 can also be electrically connected in other ways, such as the electrical connection port 10 contacting the corresponding electrical transfer port 222 and being electrically connected by screws.

[0046] In some embodiments, an insulating coating 26 is provided on the surface of the sub-copper busbar 22.

[0047] With the above structure, the insulating coating 26 further separates two adjacent sub-copper busbars 22 in the same laminated copper busbar 20, avoiding the electrical connection between two adjacent sub-copper busbars 22 in the same laminated copper busbar 20.

[0051] In addition, generally, other electronic components are installed in the air flow channel 34, and the end face of the main body 224 is parallel to the central axis of the air flow channel 34, so that the air flow at the air inlet of the air flow channel 34 is less obstructed when passing through the main body 224, and thus the air flow speed in the air flow channel 34 is relatively fast, so that the air flow in the air flow channel 34 can achieve a better heat dissipation effect on the electronic components.

[0052] Specifically, in this embodiment, the main body 30 has a structure similar to a cuboid, the air flow channel 34 is a hollow structure similar to a cuboid, one end of the air flow channel 34 is the air inlet, and the other opposite end of the air flow channel 34 is the air outlet.

[0056] In some embodiments, the sub-copper busbar 22 further includes a first folded edge portion 226, the first folded edge portion 226 is connected to the main body 224, the first folded edge portion 226 is perpendicular to the main body 224, and each electrical connection port 222 is provided on a corresponding first folded edge portion 226.

[0060] Please refer to Figure 1 、 Figure 5 and Figure 6 , in some embodiments, the main body 30 includes a housing 36 and a support column 38. The support column 38 is installed inside the housing 36, the support column 38 is connected to the housing 36, and the support column 38 is used to support the housing 36.

[0062] With the above structure, the support column 38 is used to support the housing 36, so that the housing 36 has higher stability. On the one hand, the second folded edge portion 228 is installed on the support column 38, enabling the support column 38 to support and position the sub-copper row 22, and thus the entire laminated copper row 20 can be more stably installed inside the main body 30. On the other hand, under the fixing action of the support column 38, there is a fixed gap between the inner surface of the body 224 and the housing 36, avoiding the contact between the body 224 and the inner surface of the housing 36, and further avoiding electric leakage during the operation of the charging pile 100.

[0063] Specifically, in this embodiment, the support column 38 may include a cross beam and a vertical column. The cross beam is parallel to the horizontal plane, and the vertical column is perpendicular to the horizontal plane. The housing 36 is made of a plurality of interconnected sheet metal parts; the second flanging part 228 may be a sheet-like structure similar to a rectangle.

One end of each connecting piece 50 is installed on the corresponding support column 38, and the other opposite end of each connecting piece 50 is installed on the corresponding second flanging part 228; each connecting piece 50 is perpendicular to the corresponding support column 38.

[0066] Through the above structure, under the action of the connecting piece 50, the second flanging part 228 and the corresponding support column 38 are relatively fixed, and thus the second flanging part 228 and the corresponding support column 38 do not need to be in direct contact; and in the design process, the length of the corresponding connecting piece 50 can be adjusted according to the distance between the second flanging part 228 and the corresponding support column 38, ultimately reducing the difficulty of the dimensional design of the support column 38 and the sub-copper row 22.

[0067] Specifically, in this embodiment, the connecting piece 50 has a structure similar to a cylinder; the end face of the second flanging part 228 is parallel to the end face of the corresponding support column 38. The connecting piece 50 is arranged between the support column 38 and the second flanging part 228. One end of the connecting piece 50 is installed on the corresponding second flanging part 228 by screws, and the other opposite end of the connecting piece 50 is installed on the corresponding support column 38 by screws.

[0068] In other embodiments, the connecting piece 50 may also have other structures, such as a columnar structure of a cuboid; other connection directions may also be adopted between the end of the connecting piece 50 and the second flanging part 228, and between the end of the connecting piece 50 and the support column 38, such as riveting.

[0069] In some embodiments, the number of stacked copper rows 20 is multiple. The body 224 extends in the vertical direction. All the stacked copper rows 20 are arranged in sequence in the horizontal direction. The distance between adjacent two stacked copper rows 20 is equal. All the stacked copper rows 20 are evenly arranged at the air inlet of the air flow channel 34.

[0070] The central axis of the air flow channel 34 is parallel to the horizontal plane, and the number of the air flow channels 34 is multiple. The multiple air flow channels 34 are arranged in sequence in the vertical direction.

[0071] With the above structure, all the stacked copper bars 20 are evenly arranged at the air inlet of the air flow channel 34, so that the air flow at the air inlet of the air flow channel 34 can pass through each stacked copper bar 20 more evenly, and the air flow at the air inlet of the air flow channel 34 can achieve a better heat dissipation effect on each stacked copper bar 20.

[0072] Specifically, two adjacent air flow channels 34 are in contact with each other; the multiple stacked copper bars 20 are arranged in sequence in the horizontal direction.

[0073] Please refer to Figure 7 , where H is a preset distance. In some embodiments, the charging pile 100 further includes an electrical connection line 40.

[0074] The distance from all the electrical transfer ports 222 to the corresponding electrical connection ports 10 is the preset distance, and the length of the electrical connection line 40 is adapted to the preset distance.

[0075] With the above structure, the electrical transfer port 222 and the corresponding electrical connection port 10 are electrically connected through the electrical connection line 40. Furthermore, the electrical transfer port 222 and the corresponding electrical connection port 10 do not need to be in direct contact, so that the electrical connection relationship between the electrical transfer port 222 and the corresponding electrical connection port 10 is more stable.

[0076] In addition, the distance from all the electrical transfer ports 222 to the corresponding electrical connection ports 10 is the preset distance, and the length of the electrical connection line 40 is adapted to the preset distance, so that the lengths of all the electrical connection lines 40 can be kept consistent, and further the electrical connection lines 40 can be more easily mass-produced.

[0077] Specifically, the lengths of different first folded edge parts 226 can be different, and further the distances between the electrical transfer ports 222 and the body 224 can be different, so that the distances from the electrical transfer ports 222 to the corresponding electrical connection ports 10 can be the preset distance.

[0078] In some embodiments, the electrical connection port 10 is provided with a threaded hole, the electrical transfer port 222 is a circular through hole, and each of the two ends of the electrical connection line 40 is provided with a circular through hole.

[0079] One end of the electrical connection line 40 is connected to an electrical connection port 10 through a screw, and the other end of the electrical connection line 40 is connected to the corresponding electrical transfer port 222 through a bolt.

[0080] Generally, the end of the electrical connection line 40 has a circular sheet-like structure, and the electrical transfer port 222 is a circular through-hole. The electrical transfer port 222 is provided on the first folded edge portion 226. Both the first folded edge portion 226 and the end of the electrical connection line 40 have a sheet-like structure, making it difficult to open threaded holes. Therefore, after the end of the electrical connection line 40 and the first folded edge portion 226 are overlapped, they need to be connected by bolts.

[0081] With the above structure, one end of the electrical connection line 40 is connected to an electrical connection port 10 by screws, and the other end of the electrical connection line 40 is connected to the corresponding electrical transfer port 222 by bolts, making it easier to connect the electrical connection line 40 to the corresponding electrical connection port 10, and at the same time, the electrical connection line 40 and the corresponding electrical connection port 10 are detachable from each other; it is easier to connect the electrical connection line 40 to the corresponding electrical transfer port 222, and at the same time, the electrical connection line 40 and the corresponding electrical transfer port 222 are detachable from each other.

[0082] Specifically, the electrical connection line 40 can be a wire wrapped with insulating cloth, and an annular metal is provided at each end of the electrical connection line 40. One of the annular metals is used to connect to the corresponding electrical transfer port 222, and the other annular metal is used to connect to the corresponding electrical connection port 10.

[0083] Please refer back to Figure 1 , in some embodiments, the electrical connection port 10 includes a DC port, an AC port, and a power module port.

[0084] With the above structure, the sub-copper busbar 22 can electrically connect the interfaces in different areas of the charging pile 100 to each other, and can also electrically connect the interfaces in the same area of the charging pile 100 to each other.

[0085] Specifically, the charging pile 100 includes a DC area 60, an AC area 70, and a power module area 80. The DC port is located in the DC area 60, the AC port is located in the AC area 70, and the power module port is located in the power module area 80. From top to bottom, the DC area 60, the power module area 80, and the AC area 70 are arranged in sequence within the main body 30.

[0086] The sub-copper busbar 22 can be connected between two DC ports, or between a DC port and a power module port, or between an AC port and a power module port, or between two AC ports.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; under the idea of the present invention, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above. For the sake of brevity, they are not provided in detail; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
