[0030] The utility model provides a kind of charging pile host structure, and the charging pile host structure includes cabinet 1, and cabinet 1 includes top plate 12 and bottom plate 14 distributed along height direction and the side wall 15 connected between top plate 12 and bottom plate 14, to define the cavity for containing being enclosed.Therein, each unit component of charging cabinet host is accommodated in the cavity for containing.

[0031] Cabinet 1 is equipped with the line inlet 21 and the line outlet 22 that can be opened or closed in the both ends of first set direction, and the line inlet 21 and the line outlet 22 can be connected with the cavity for containing and external communication.The line inlet 21 allows alternating current incoming cable 42 to pass through, from outside into the cavity for containing, and carries out electrical connection with rectifier device in the cavity for containing.The line outlet 22 allows direct current outgoing cable 41 to pass through, from the cavity for containing to the outside and exports to terminal.Direct current outgoing cable 41 is connected between rectifier device and terminal, alternating current incoming cable is connected between power supply and rectifier device, "AC" is input to rectifier device by alternating current incoming cable 42, and "DC" is exported to terminal by direct current outgoing cable 41 after rectification.

[0033] In some other optional embodiments, the second set direction is defined as being in the same plane with first set direction and being perpendicular to first set direction, i.e., if the first set direction is the height direction of the cabinet 1, the second set direction is the width direction of the cabinet 1.

[0034] The accommodation cavity is divided into a first accommodation area 31 and a second accommodation area 32, the two accommodation areas are used to accommodate different unit components, and the alternating current incoming line cable 42 is correspondingly connected to one of the first accommodation area 31 and the second accommodation area 32, and the direct current outgoing line cable 41 is correspondingly connected to the other of the first accommodation area 31 and the second accommodation area 32. For example, the wiring inlet 21 corresponds to the first accommodation area 31, and the wiring outlet 22 corresponds to the second accommodation area 32.

[0037] In some more specific embodiments, two first accommodation areas 31 and one second accommodation area 32 are arranged in the accommodation cavity, and in the second set direction, the second accommodation area 32 is located between the two first accommodation areas 31. In this embodiment, the number of the first accommodation area 31, which can be two, is adapted as the alternating current output side, that is, corresponding to the wiring inlet 21, so that the output power of the charging host can be adjusted as needed.

[0038] In a specific embodiment, the first accommodation area 31 is divided into two sub-areas, that is, a rectifier module area 31a and an alternating current input area 31b, and the alternating current input area 31b can be a corresponding structure of a wiring copper bar. The rectifier module area 31a and the alternating current input area 31b form an electrical connection. The rectifier module area 31a and the alternating current input area 31b are distributed along the first set direction; the alternating current input area 31b has a wiring side, which is located on the side of the alternating current input area 31b away from the rectifier module area 31a. In this way, the layout mode of the unit components in the accommodation area can be more compact, and the wiring operation can be facilitated.

[0039] The second-class accommodation area 32 is divided into two sub-areas: a core control area 32a and a DC output area 32b. The core control area 32a and the DC output area 32b are arranged along a first predetermined direction. The DC output area 32b has a wiring side located on the side of the DC output area 32b away from the core control area 32a.

In the following embodiments, the first setting direction is the height direction of the cabinet 1 and the second setting direction is the width direction of the cabinet 1 as an example for explanation.

[0041] In the following embodiments, the AC input area 31b is located below the rectifier module area 31a; the DC output area 32b is located below the core control area 32a. Of course, the AC input area 31b can also be located above the rectifier module area 31a, and the DC output area 32b can also be located above the core control area 32a. The layout arrangements described in this application, as well as equivalent alternatives, are all within the scope of protection of this application. In the following embodiments, the same content may apply individually or in combination, and the description will focus on the different parts.

[0042] Example 1

[0043] In this embodiment, the method of routing the wiring on the bottom side of the charging cabinet host is described.

[0044] In this embodiment, the wiring inlet 21 and the wiring outlet 22 located at the top of the cabinet 1 are both in a closed state.

[0045] The AC incoming cable 42 enters the first storage area through the bottom wiring entrance 21 and connects to the connection side of the AC input area 31b. The DC outgoing cable 41 is located in the second storage area and extends out of the second storage area through the bottom wiring exit 22 to connect to the charging terminal.

[0046] In the embodiment of the present application, two groups of wiring entrances 21 are provided in the width direction, respectively adapted to the first accommodation area on the corresponding side, and the wiring exit 22 is located between the two groups of wiring entrances 21 in the width direction and adapted to the second accommodation area.

[0047] Example 2

[0048] In this embodiment, different from the first embodiment, the wiring is routed from the top of the cabinet 1, and at the same time, the wiring side of the DC output area 32b is facing the bottom of the cabinet 1, and the wiring side of the AC output area is also facing the bottom of the cabinet 1.

[0049] In the present embodiment, the cabinet 1 further comprises a plurality of support beams 11 extending along the first direction, the support beams 11 are used to divide the first type of accommodation area 31 and the second type of accommodation area 32, and the support beams 11 are located in the cabling area 33.

[0050] In the process of cabling, the support beams 11 are used as the support for the cables, and at the same time, the utilization rate of the space where the support beams 11 are located can be improved.

[0051] As shown in the figure, the AC incoming cable 42 enters the cabling area 33 through the incoming port provided at the top, at this time, the incoming port at the bottom is in a closed state, the AC incoming cable 42 moves downward along the cabling area 33, and then turns horizontally to the opposite side of the wiring side at the bottom of the AC input area 31b and is connected opposite to it. The DC outgoing cable 41 is connected opposite to the terminal through the cabling outlet 22 provided at the top, specifically, one end of the DC outgoing cable 41 is connected opposite to the wiring side at the bottom of the DC output area 32b, then extends outward in the horizontal direction to the cabling area 33, and moves upward through the cabling area 33 until it extends to the outside of the second accommodation area through the cabling outlet 22.

[0052] Embodiment three

[0053] In the present embodiment, the single-side cabling mode in the first embodiment and the second embodiment is changed to a double-side cabling mode, in the example shown in the figure, the DC outgoing cable 41 is outgoing from the bottom, and the AC incoming cable 42 is incoming from the top.

[0054] Specifically, the cabling inlet 21 at the top of the cabinet 1 is opened, and the cabling outlet 22 at the bottom is closed. After the AC incoming cable 42 enters the cabling area 33, it extends downward, and then moves outward horizontally to be connected to the bottom of the AC input area 31b. The cabling inlet 21 at the bottom of the cabinet 1 is closed, and the cabling outlet 22 at the bottom is opened. The DC outgoing cable 41 directly extends downward and extends out of the cabinet 1 from the bottom.

[0055] Embodiment four

[0056] The same as the third embodiment, the present embodiment also adopts the mode of cabling from the top and the bottom, the difference is that the DC outgoing cable 41 does not extend outward through the cabling outlet 22 at the bottom, but extends out of the cabinet 1 through the cabling outlet 22 at the top after passing through the cabling area 33. The AC incoming cable 42 does not enter the cabinet 1 through the cabling inlet 21 at the top, but enters the cabinet 1 through the cabling inlet 21 at the bottom.

[0057] In the above-mentioned embodiments, in order to prevent water from entering the cabling inlet 21 and the cabling outlet 22 provided at the top, the top plate 12 is further provided with a plurality of ring plates 13, the ring plates 13 are provided perpendicularly to the top plate 12, and are arranged around the corresponding cabling inlet 21 or cabling outlet 22.

[0058] In order to block the wire inlet 21 and the wire outlet 22 arranged at the top, a top cover 23 is arranged, which is nested with the ring plate 13 to block the wire inlet 21 and the wire outlet 22 on the top plate 12.

[0059] In order to block the wire inlet 21 and the wire outlet 22 arranged at the bottom, the cabinet 1 further comprises a bottom plate 14 arranged opposite to the top plate 12 in the height direction; the bottom plate 14 is also provided with the wire inlet 21 and the wire outlet 22; the bottom plate 14 is further provided with a bottom cover 24, which is used to block the wire inlet 21 and the wire outlet 22 on the bottom plate 14.

[0060] Compared with the prior art, the technical scheme of the present application not only is compatible with the wire arrangement mode of the bottom inlet and outlet, but also can be "bottom inlet and top outlet" and "top inlet and bottom outlet". Thus, various wire arrangement schemes can be met, and the flexibility of wire arrangement is improved; at the same time, it is not necessary to select the corresponding wire arrangement mode according to the design of each component in the host computer. When the host computer is designed as the bottom inlet and outlet, the cable can not only be selected to be arranged from the bottom of the charging host computer, but also can be arranged from the top or simultaneously arranged from the top and the bottom. Conversely, when the host computer is designed as the top outlet, the wire arrangement mode still has many choices, which expands the selectability of the user and saves the research and development and operation and maintenance cost of the company.

[0061] In the present application, specific examples are applied to describe the principle and implementation mode of the present application. The above description of the embodiments is only used to help understand the core idea of the present application. It should be pointed out that, for ordinary skilled in the art, without departing from the principle of the present application, the present application can be improved and modified in many ways, and these improvements and modifications also fall within the protection scope of the claims of the present application.
