[0025] Example:

[0026] like Figure 1-6As shown, in this embodiment, the charging pile host includes: a cabinet 1, a fixing component 2, an AC input unit 3, an AC contactor 4, a power module 5, a power distribution module 6, and a DC output unit 7; the AC input unit 3 is connected to the AC contactor 4 through a first metal conductive busbar 31, the AC contactor 4 is connected to the power module 5 through a second metal conductive busbar 32, the power module 5 is electrically connected to the power distribution module 6, and the power distribution module 6 is connected to the DC output unit 7 through a third metal conductive busbar 61; the cabinet 1 is provided with a front door 11 and a rear door 12, the fixing component 2 defines a first assembly area and a second assembly area that are arranged side by side in the cabinet 1, the AC input unit 3 and the AC contactor 4 are both fixed at a first height position in the first assembly area, and the AC input unit 3 and the AC contactor 4 are arranged front to back, the power module 5 is fixed at a second height position in the first assembly area; the power distribution module 6 and the DC output unit 7 are both fixed in the second assembly area, and the power distribution module 6 and the DC output unit 7 are arranged front to back.

[0027] Specifically, the key components of the charging pile host are made into multiple independent unit modules (i.e., AC input unit 3, AC contactor 4, power module 5, power distribution module 6, and DC output unit 7). Each unit module can be assembled and tested independently before being installed in the cabinet 1. The AC input unit 3 and AC contactor 4, the AC contactor 4 and power module 5, and the power distribution module 6 and DC output unit 7 are connected by metal conductive busbars, which takes up little space and improves the utilization rate of the charging pile host assembly space. It can also effectively reduce cable costs, improve the orderliness of assembly, and improve the accuracy of assembly and disassembly, preventing tangled wires and reducing the possibility of incorrect wiring or disconnection. Moreover, the charging pile host of this embodiment optimizes the assembly position of each unit module. Any unit module can be directly assembled or disassembled by opening the front door 11 or the rear door 12 without the need for step-by-step assembly and disassembly, which helps to reduce later maintenance costs.

[0028] In this embodiment, during the operation of the charging pile host, the transmission path of AC power between the various unit modules is as follows: AC input unit 3 → AC contactor 4 → power module 5 → power distribution module 6 → DC output unit 7.

[0029] like Figure 1-3As shown, in this embodiment, the fixing component 2 includes a frame 21 fixed inside the cabinet 1, a first support plate 22 fixed on the frame 21, and a fixing beam 23. The frame 21, the first support plate 22, and the fixing beam 23 enclose a plurality of mounting cavities a adapted to the power distribution module 6 in the second assembly area. Each mounting cavity a is respectively installed with a power distribution module 6. The fixing beam 23 is located at the rear end of the mounting cavity a. Each third metal conductive busbar 61 corresponding to each mounting cavity a is fixed on the fixing beam 23.

[0030] Specifically, each power distribution module 6 can be installed into its corresponding mounting cavity a from the front of the cabinet 1; the DC output unit 7 can be fixed to the rear end of the mounting cavity a, that is, fixed to the side of the fixing beam 23 away from the third metal conductive busbar 61. In this embodiment, the fixing beam 23 can be a sheet metal fastener, and there can be one or more fixing beams 23, which is not limited here. In some specific embodiments, 10 independent power distribution modules 6 can be set and arranged in two rows, one above the other, by the first support plate 22 in the cabinet 1. Each power distribution module 6 can also be reinforced and fixed to the frame 21 by screws. In use, the appropriate power distribution module 6 can be selected and inserted into the corresponding mounting cavity a according to different needs, which is beneficial to improving the adaptability of the charging pile. At the rear end of the power distribution module 6, different combinations of metal conductive busbars can be used to realize the output of power units and the merging of power units, which is beneficial to maximizing power utilization. A handle can also be set at the front end of the power distribution module 6 to facilitate installation, disassembly, and extraction operations, improving the convenience of assembly and subsequent maintenance.

[0031] Furthermore, such as Figure 3 As shown, in this embodiment, a first positioning block 27 is provided between adjacent mounting cavities a, and the first positioning block 27 is fixed to the first support plate 22. The first positioning block 27 can not only position the two adjacent power distribution modules 6, but also play a guiding role in the assembly process. That is, during assembly, the power distribution module 6 can be directly inserted into the mounting cavity a. During the insertion process, the first positioning block 27 can automatically prevent the power distribution module 6 from shifting, making the assembly operation simple.

[0032] like Figure 1 , 2As shown in Figure 4, in this embodiment, the fixing component 2 further includes a second support plate 24 fixed to the frame 21. The frame 21 and the second support plate 24 enclose a plurality of assembly cavities b adapted to the power module 5 in the first assembly area, and a power module 5 is installed in each assembly cavity b respectively. The AC input unit 3 and the AC contactor 4 are respectively fixed on the bottom side of the assembly cavity b. A clearance opening is also formed between the second support plate 24 and the frame 21. One end of the second metal conductive bus 32 is connected to the output end of the top of the AC contactor 4, and the other end passes through the clearance opening and extends into the assembly cavity b to connect with the corresponding power module 5.

[0033] Specifically, this embodiment includes multiple power modules 5, for example, up to 20 power modules 5. Each power module 5 is independent and embedded in its corresponding assembly cavity b. Each power module 5 can be reinforced and fixed to the fixing component 2 with screws to ensure stability during transportation, enabling transport with modules and facilitating user use.

[0034] Furthermore, such as Figure 4 As shown, in this embodiment, a second positioning block 28 is also provided between adjacent assembly cavities b, and the second positioning block 28 is fixed to the second support plate 24. The second positioning block 28 can not only position the two adjacent power modules 5, but also play a guiding role in the assembly process. That is, during assembly, the power module 5 can be directly inserted into the assembly cavity b. During the insertion process, the second positioning block 28 can automatically prevent the power module 5 from shifting, making the assembly operation simple.

[0035] like Figure 5 and 6 As shown, in this embodiment, the fixing component 2 further includes a first fixing block 25 and a second fixing block 26 fixed to the frame 21 and spaced apart from each other. A plurality of AC contactors 4 are fixed on the first fixing block 25, and a plurality of AC input units 3 are fixed on the second fixing block 26. The first metal conductive busbar 31 includes a first connecting section 311, a second connecting section 312, and an intermediate section 313 bent and connected between the first connecting section 311 and the second connecting section 312. The intermediate section 313 is located between the first fixing block 25 and the second fixing block 26. The end of the first connecting section 311 away from the intermediate section 313 is connected from the top of the AC input unit 3 to the output end of the corresponding AC input unit 3. The end of the second connecting section 312 away from the intermediate section 313 is connected from the bottom side of the AC contactor 4 to the input end of the corresponding AC contactor 4.

[0036] Specifically, both the first fixing block 25 and the second fixing block 26 can be sheet metal fasteners. Multiple AC contactors 4 are fixed side-by-side on the same first fixing block 25, and multiple AC input units 3 are fixed side-by-side on the same second fixing block 26. The assembly is orderly and convenient for assembly and disassembly. A clearance is provided between the first fixing block 25 and the second fixing block 26 to optimize the structure of the first metal conductive busbar 31. The bending design of the first metal conductive busbar 31 can effectively shorten the wiring distance between the AC input unit 3 and the corresponding AC contactor 4, and also improve the utilization rate of the assembly space.

[0037] In this embodiment, as Figure 2 As shown, the DC output unit 7 includes multiple fourth metal conductive bars corresponding to multiple power distribution modules 6. Each metal conductive bar is fixed on the side of the fixed beam 23 away from the third metal conductive bar 61, and each fourth metal conductive bar is connected to the corresponding third metal conductive bar 61.

[0038] Specifically, multiple fourth metal conductive busbars are fixed side-by-side on the fixing beam 23. Each fourth metal conductive busbar is an independent wiring unit, and can be directly installed or removed by opening the rear door 12 of the cabinet 1, making operation simple. It should be noted that in this embodiment, the metal conductive busbars can be copper or aluminum busbars. That is, all metal conductive busbars involved in this embodiment can be selected from copper or aluminum busbars, etc., to achieve circuit connection and conduction according to actual needs, and there is no limitation here. Each metal conductive busbar can be fixed to the fixing component 2 by screws.

[0039] In this embodiment, as Figure 1 and 2 As shown, the front door 11 has an air inlet, and a first air duct shell 13 is provided on the inner side of the front door 11. The first air duct shell 13 and the front door 11 enclose an air intake channel, and the outlet of the air intake channel is located on the side of the air duct shell. Specifically, through the design of the first air duct shell 13, the cold air, after reaching the front door 11, first passes through the air intake channel, and then exits from the side of the air duct shell to reach the cabinet; this extends the air duct and can also effectively reduce wind resistance and noise. In some more specific embodiments, two front doors 11 can be symmetrically arranged, that is, a left front door 11 and a right front door 11 are respectively hinged to the left and right sides of the cabinet 1. The left front door 11 and the right front door 11 can be respectively enclosed with the corresponding first air duct shell 13 to form corresponding air intake channels. This arrangement of multiple air intake paths is beneficial to improving the heat dissipation efficiency of the charging pile host. Furthermore, in some specific embodiments, a filter screen 131 is provided at the outlet of the air intake channel, which can effectively remove dust and impurities in the air and prevent the components inside the cabinet from being affected by dust and impurities.

[0040] In this embodiment, the rear door 12 is provided with an air outlet, and a second air duct shell 14 is provided on the inner side of the rear door 12. The second air duct shell 14 and the rear door 12 enclose an air outlet channel, and a fan 15 is provided at the entrance of the air outlet channel.

[0041] Specifically, the fan 15 can be used to guide the hot airflow inside the cabinet to the exhaust duct, allowing the hot airflow to quickly reach the outside of the cabinet 1 for efficient heat dissipation. In this embodiment, the second air duct shell 14 simultaneously serves the purposes of fixing the fan 15 and forming an exhaust duct. In some specific embodiments, two rear doors 12 can be symmetrically arranged, namely, a left rear door 12 and a right rear door 12 respectively hinged to the left and right sides of the cabinet. The left and right rear doors 12 can be respectively enclosed with the corresponding second air duct shell 14 to form corresponding exhaust ducts. By setting multiple exhaust paths in this way, the heat dissipation efficiency of the charging pile host can be further improved.

[0042] This embodiment also includes a control unit. The control unit can transmit signals to components such as the AC input unit 3, AC contactor 4, power module 5, and power distribution module 6 via wired and / or wireless connections to achieve signal control of the entire unit. In some specific embodiments, a display screen for the control unit can be installed on the front door 11 or rear door 12 of the cabinet 1. This allows for better display of the charging pile host's operating status information, and thus more efficient control of the various unit modules within the charging pile host to coordinate and complete related tasks.

[0043] The above are merely preferred embodiments of the present utility model and are 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.
