In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0036] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0037] A power distribution unit 100 provided in an embodiment of the present application is described in detail below through specific embodiments in conjunction with all the drawings in the specification.

[0038] Please refer to Figure 1 , Figure 2 and Figure 3In one embodiment of the utility model, a power distribution unit 100 is disclosed, including a housing 10, an electrical socket 20 and a power distribution module 30. The housing 10 is provided with an installation cavity 102. The electrical socket 20 is installed in the housing 10, and the electrical socket 20 penetrates the cavity wall of the installation cavity 102. The power distribution module 30 is located in the installation cavity 102.

The switch component 33 is used to control the second electrical connection end 344 to be electrically connected or disconnected with a power source.

[0039] Each switch element 33 can control a power source to be connected to the first electrical connector 34, so that the first electrical connector 34 can charge the device connected to the electrical socket 20; when different numbers of switch elements 33 simultaneously control the corresponding power sources to be connected to the first electrical connector 34, the total power output by the first electrical connector 34 will be different.

[0040] Through the above structure, when the power distribution unit 100 needs to replace the power distribution module 30 according to the actual application situation, it is only necessary to remove the power distribution module 30 relative to the shell 10, and then install the new power distribution module 30 into the shell 10, so that the charging pile can have different power distribution parameters, reducing the replacement cost of the power distribution module 30. The power distribution units 100 with different power distribution modules 30 can have the same outer shape of the shell 10, which is convenient for installing the power distribution units 100 with different power distribution modules 30 into the cabinet of the charging pile to achieve modular assembly.

[0041] In addition, when the switch component 33 and the second adapter 32 are matched in different ways, different power distribution modules 30 can be formed. For example, when three second adapters 32 are provided on the first adapter 31 and each second adapter 32 is connected to a switch component 33, the power distribution module 30 is of the first model. When the first second adapter 32 and the second second adapter 32 are connected to a switch component 33, the power distribution module 30 is of the second model. When the first second adapter 32 and the third second adapter 32 are connected to a switch component 33, the power distribution module 30 is of the third model. In addition, different power distribution modules 30 can share the same first adapter 31, and the parts of the power distribution module 30 are easy to mass-produce.

[0042] Specifically, in this embodiment, the housing 10 is a hollow rectangular structure, and the mounting cavity 102 passes through the top of the housing 10. There are multiple electrical sockets 20, all of which pass through the same cavity wall of the mounting cavity 102, and the electrical sockets 20 are arranged in a row along the horizontal direction, and the portion of the electrical socket 20 located in the mounting cavity 102 is used for electrical connection with the first electrical connection end 342, and the portion of the electrical socket 20 located outside the mounting cavity 102 is used for connection with external equipment.

[0043] The first adapter 31 is a plate-like structure, and the first adapter 31 is detachably connected to the bottom cavity wall of the installation cavity 102 through a threaded connector. The second adapter 32 is a threaded hole opened on the first adapter 31, and the switch 33 is detachably connected to the second adapter 32 through a threaded connector. The switch 33 is a structure similar to a rectangular parallelepiped, and a protrusion 334 is provided on both sides of the bottom of the switch 33, and a threaded hole is opened on the protrusion 334, and the threaded connector is sequentially inserted through the threaded hole on the protrusion 334 and the second adapter 32.

[0044] There are multiple first electrical connectors 34, which are arranged in a row. The first electrical connector 34 is a copper strip-shaped sheet structure. The first electrical connector 34 may include one or more second electrical connection ends 344. The first electrical connection end 342 is located at one end of the first electrical connector 34, one of the second electrical connection ends 344 is located at the other end of the first electrical connector 34, and the other second electrical connection end 344 protrudes relative to the side of the first electrical connector 34. The second electrical connection end 344 is detachably connected to the top of the switch element 33 through a threaded connector, so that the second electrical connection end 344 is electrically connected to the switch element 33.

[0045] In other embodiments, the housing 10 may also be in other shapes, such as a hollow cylindrical structure. The second adapter 32 may also be other, such as a snap-on or plug-in connector, and the corresponding switch 33 may also be detachably connected to the second adapter 32 by snap-on or plug-in. The switch 33 may also be in other shapes, such as a triangular prism. The second electrical connection end 344 may also be plugged into the side of the switch 33.

[0046] In some embodiments, the first adapter 31 is a plate-shaped structure, the second adapter 32 is a mounting hole, and the second adapter 32 is opened on the first adapter 31 .

[0047] Through the above structure, the first adapter 31 is easier to produce, and the switch component 33 is easier to connect to the second adapter 32 .

[0048] Specifically, the mounting hole is a threaded hole, the first adapter 31 is a rectangular metal plate, the second adapter 32 is divided into multiple groups, each group of second adapters 32 corresponds to a switch 33, the number of each group of second adapters 32 is two, and the multiple groups of second adapters 32 are arranged in three parallel rows. A second adapter 32 is provided at one end of each first electrical connector 34 away from the electrical socket 20, and a second adapter 32 is also provided between two adjacent first electrical connectors 34.

[0049] In some embodiments, the first adapter 31 includes a main body 312, a first folded edge 314 and a second folded edge 316, the main body 312 includes a first side edge 3122 and a second side edge 3124 arranged opposite to each other, the first folded edge 314 is connected to the first side edge 3122, the second folded edge 316 is connected to the second side edge 3124, the first folded edge 314 and the second folded edge 316 are both installed on the bottom cavity wall of the installation cavity 102, and there is a gap between the main body 312 and the bottom cavity wall of the installation cavity 102.

[0050] Through the above structure, the first folded edge 314 and the second folded edge 316 support the main body 312, so that there is a gap between the main body 312 and the bottom cavity wall of the installation cavity 102, and thus there is a certain space when the switch component 33 and the second adapter 32 are threadedly connected. The threaded connector passing through the switch component 33 and the second adapter 32 will not contact the bottom cavity wall of the installation cavity 102, and thus the power distribution module 30 is easier to pre-install.

[0051] Specifically, in the present embodiment, the first folded edge 314 and the second folded edge 316 are both in a strip-shaped structure, and the first folded edge 314 and the second folded edge 316 are both detachably connected to the bottom cavity wall of the installation cavity 102 by means of threaded connection. In other embodiments, the first folded edge 314 and the second folded edge 316 may also be in other structures, such as a block shape. The first folded edge 314 and the second folded edge 316 may also be connected to the bottom cavity wall of the installation cavity 102 by other means, such as clamping.

[0052] Please refer to Figure 4 In some embodiments, the first folded edge 314 includes a first vertical section 3144 and a first parallel section 3142, the first vertical section 3144 is perpendicular to the body 312, and the first parallel section 3142 is parallel to the body 312; one end of the first vertical section 3144 is connected to the body 312, and the other end of the first vertical section 3144 is connected to the first parallel section 3142, and the first parallel section 3142 is detachably connected to the bottom cavity wall of the mounting cavity 102.

[0053] The second folded edge 316 includes a second vertical section 3164 and a second parallel section 3162, the second vertical section 3164 is perpendicular to the main body 312, and the second parallel section 3162 is parallel to the main body 312; one end of the second vertical section 3164 is connected to the main body 312, and the other end of the second vertical section 3164 is connected to the second parallel section 3162, and the second parallel section 3162 is detachably connected to the bottom cavity wall of the installation cavity 102.

[0054] Through the above structure, during the mutual assembly of the power distribution module 30 and the housing 10, the first parallel section 3142 and the second parallel section 3162 can abut against the bottom cavity wall of the installation cavity 102, so that the power distribution module 30 is difficult to shake relative to the housing 10, making it easier to install the power distribution module 30 into the housing 10. In addition, one surface of the first parallel section 3142 contacts the bottom cavity wall of the installation cavity 102, and at the same time, one surface of the second parallel section 3162 also contacts the bottom cavity wall of the installation cavity 102, so that the first folded edge 314 and the second folded edge 316 can provide a more stable support for the body 312.

[0055] Specifically, in this embodiment, the first folded edge 314 and the second folded edge 316 have the same structure, the first vertical section 3144 and the first parallel section 3142 are both rectangular sheet structures, and the body 312 and the first parallel section 3142 are respectively located on both sides of the first vertical section 3144. The number of the first folded edge 314 and the second folded edge 316 are both one, and the length of the first folded edge 314, the length of the first side 3122, the length of the second folded edge 316, and the length of the second side 3124 are all equal.

[0056] In other embodiments, the body 312 and the first parallel section 3142 may also be located on the same side of the first vertical section 3144. There may also be multiple first folded edges 314, the length of the first folded edges 314 is less than the length of the first side edge 3122, and all first folded edges 314 are arranged in a row along the first side edge 3122.

[0057] Please refer to Figure 5 In some embodiments, the switch member 33 includes a partition member 332 and at least two electrical connection ports 3302 , the partition member 332 is located between the two electrical connection ports 3302 , the partition member 332 separates all the electrical connection ports 3302 from each other, and the second electrical connection end 344 is electrically connected to the electrical connection port 3302 .

[0058] Through the above structure, the partition member 332 can separate all the electrical connection ports 3302 on the same switch member 33 from each other, so that different second electrical connection terminals 344 connected to the same switch member 33 will not directly contact each other, thereby improving the reliability of the switch member 33.

[0059] Specifically, in the present embodiment, the switch component 33 is similar to a rectangular parallelepiped structure, the electrical connection port 3302 is opened at the top of the switch component 33, each switch component 33 includes two electrical connection ports 3302, the partition component 332 is a rectangular sheet structure, the partition component 332 is perpendicular to the top wall of the switch component 33, the partition component 332 is located between the two electrical connection ports 3302, and the two electrical connection ports 3302 are symmetrically arranged along the partition component 332.

[0060] In other embodiments, each switch member 33 may also include other numbers of electrical connection ports 3302, such as three. The partition member 332 may also be other structures, such as a sheet-like structure with arc-shaped sides.

[0062] Through the above structure, different switch components 33 connected to the same first electrical connector 34 can be opened and closed independently, and thus different switch components 33 connected to the same first electrical connector 34 can independently transmit electrical energy to the corresponding electrical socket 20 via the first electrical connector 34, so that the same electrical socket 20 can output different powers.

[0063] In addition, when the second electrical connection end 344 is connected to the switch component 33, the switch component 33 can support the first electrical connection component 34 through the second electrical connection end 344. When the first electrical connection component 34 is provided at the end and side of the first electrical connection component 34, the side and end of the first electrical connection component 34 can be supported by the switch component 33, so that the first electrical connection component 34 is more stable.

[0064] Specifically, all the first electrical connectors 34 are arranged in a row, the first electrical connectors 34 located on both sides of the shell 10 include two second electrical connection ends 344, and the other first electrical connectors 34 include three second electrical connection ends 344.

[0066] Through the above structure, at least two switch components 33 can be electrically connected to the same first electrical connector 34 through the second electrical connector 35, and then the same first electrical connector 34 can be electrically connected to more switch components 33, so that the first electrical connector 34 has a larger maximum output power. In addition, under the action of the second electrical connector 35, the first electrical connector 34 can be electrically connected to the switch component 33 that is far away.

[0067] Specifically, the second electrical connector 35 is a sheet-like structure similar to a rectangle, and the third electrical connector end 352 and the fourth electrical connector end 354 are both located on the same side of the second electrical connector 35. The power distribution module 30 also includes a support column 36, the bottom of the support column 36 is connected to the second adapter 32, and the top of the support column 36 is used to support the third electrical connector end 352 and the second electrical connector end 344 that are electrically connected to each other, so that the third electrical connector end 352 and the second electrical connector end 344 can be stably electrically connected.

[0068] In this embodiment, each second electrical connector 35 includes two fourth electrical connection ends 354 . In other embodiments, each second electrical connector 35 may also include another number of fourth electrical connection ends 354 , such as three.

The support member 40 is installed on the bottom cavity wall of the installation cavity 102. The support member 40 is located in the installation cavity 102. One end of the electrical adapter 37 is electrically connected to the electrical socket 20, and the other end of the electrical adapter 37 is electrically connected to the first electrical connection end 342. The two ends of the electrical adapter 37 are located at different heights, and the support member 40 supports the electrical adapter 37.

[0070] Through the above structure, the support member 40 is used to support the electrical adapter 37 so that the electrical adapter 37 can be installed in the installation cavity 102. The electrical socket 20 and the first electrical connection end 342 are located at different heights. The electrical adapter 37 is used for the first electrical connection member 34 to be electrically connected to the electrical socket 20.

[0071] Specifically, the support member 40 is a block-shaped structure similar to a rectangle, each first electrical connector 34 corresponds to an electrical adapter 37 , and the support member 40 supports all the electrical adapters 37 simultaneously.

[0072] In some embodiments, the electrical adapter 37 includes a third vertical segment 372, a third parallel segment 374 and a fourth parallel segment 376, the third parallel segment 374 is connected to one end of the third vertical segment 372, the fourth parallel segment 376 is connected to the other end of the third vertical segment 372, the end of the third parallel segment 374 facing away from the third vertical segment 372 is electrically connected to the electrical socket 20, the end of the fourth parallel segment 376 facing away from the third vertical segment 372 is electrically connected to the first electrical connection end 342, and the support member 40 supports the fourth parallel segment 376.

The third parallel section 374 and the fourth parallel section 376 are parallel to each other. The third vertical section 372 abuts against a side surface of the support member 40 .

[0075] In some embodiments, the support member 40 defines a strip-shaped groove 402 , and the first electrical connection end 342 and the fourth parallel section 376 are both located in the strip-shaped groove 402 .

[0076] Through the above structure, the strip groove 402 limits the fourth parallel section 376, so that one end of the electrical adapter 37 is easier to align with the corresponding first electrical connection end 342, and the other end of the electrical adapter 37 is easier to align with the corresponding electrical socket 20.
