[0030] In the following description, specific details such as specific system structures and technologies are provided for illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known technologies, algorithms, and electronic devices are omitted to avoid obstructing the description of the present application with unnecessary details.

[0031] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the specification and appended claims of this application, the singular expressions "a," "said," "above," and "the" are intended to also include expressions such as "one or more," unless the context clearly indicates otherwise.

[0032] With the continuous development of electric vehicles, charging piles for electric vehicles are gradually being promoted. Charging piles may include: power distribution units, charging modules and charging interfaces, etc.

[0033] In the related art, the power distribution unit is located between the charging module and the charging interface. The power distribution unit controls the power output by the charging module to the charging interface based on the received information, thereby realizing the distribution of the charging power.

[0034] However, as the battery capacity of electric vehicles continues to increase, the required charging power also increases accordingly, and the output terminals in the power distribution unit also continue to increase, thereby affecting the stability of each output terminal in the power distribution unit.

[0035] Therefore, an embodiment of the present application proposes a power distribution unit, which includes an output terminal, a power distribution board, and a switch array disposed within a housing, and a stabilizer secured to the housing surface through a through hole in the housing. One end of the output terminal can be connected to the stabilizer, and a switch array corresponding to the power distribution board can be disposed on a side of the power distribution board away from the output terminal. The switch array is connected to the output terminal via a metal connector. By disposing the stabilizer within the housing, connecting the output terminal to the stabilizer, and securing each output terminal via the stabilizer, the stability of the output terminal within the power distribution unit can be improved, thereby enhancing the reliability and safety of the power distribution unit.

[0036] See also Figure 1 , Figure 1 This is a schematic diagram of a scenario corresponding to a charging device involved in a power distribution unit proposed in an embodiment of the present application. The schematic diagram of the scenario may include: a charging device 10 and an electric vehicle 20.

[0037] The charging device 10 may include: a power distribution unit 101 , a charging module 102 and a charging interface 103 , and the power distribution unit 101 is connected to the charging module 102 and the charging interface 103 .

[0038] Correspondingly, the charging module 102 can supply energy to the power distribution unit 101, and the power distribution unit 101 can adjust the charging power when the charging module 102 supplies energy, and supply energy to the charging interface 103 according to the adjusted charging power, and the charging interface 103 can charge the device according to the adjusted charging power, that is, the charging device 10 can charge the electric vehicle 20 through the charging interface 103.

[0039] It should be noted that, in actual applications, the charging device 10 can be a charging pile or other device capable of charging, and the present embodiment does not specifically limit the type of the charging device 10. In addition, the present embodiment uses an electric vehicle as an example for explanation, but in actual applications, the charging device 10 can also charge electric bicycles, electric motorcycles, or other electric travel devices, and the present embodiment does not specifically limit this.

[0040] The following is a detailed introduction to the power distribution unit in the charging device.

[0041] Figure 2 This is a schematic diagram of the structure of a power distribution unit provided in an embodiment of the present application, which is used as an example but not as a limitation for the above-mentioned charging device. Figure 2 The power distribution unit may include: a housing 201 , a stabilizing member 202 , an output terminal 203 , at least one power distribution board 204 and at least one switch array 205 .

[0042] There is a one-to-one correspondence between at least one power distribution board 204 and at least one switch array 205. Furthermore, the output terminal 203 may be a copper busbar, an aluminum busbar, or other conductors, and the embodiment of the present application does not specifically limit the output terminal 203.

[0043] Specifically, the output terminal 203, each power distribution board 204 and each switch array 205 can be located inside the shell 201, and the stabilizing member 202 can be clamped on the surface of the shell 201 through a through hole pre-set in the shell 201. One end of the output terminal 203 can be connected to the stabilizing member 202, so that the output terminal 203 can be fixed by the stabilizing member 202.

[0044] Moreover, a switch array 205 corresponding to the power distribution board 204 is provided on a side of the power distribution board 204 away from the output terminal 203 . The switch array 205 can be connected to the output terminal 203 via a metal connector.

[0045] In addition, the stabilizer 202 may be provided with a plurality of through-holes, and the end of the output terminal 203 connected to the stabilizer 202 may extend through the through-hole to the outside of the housing 201. This allows heat dissipation through the output terminal 203 extending outside the housing 201, thereby improving the safety of the power distribution unit. Furthermore, the output terminal 203 extending outside the housing 201 may also be connected to a corresponding output interface, thereby outputting current to the charging interface through the output interface.

[0046] Optional, see Figure 3 , Figure 3 A schematic diagram of the structure of a stabilizing member provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the stabilizing member 202 may be provided with a mounting hole 202a, and the housing 201 may be provided with a positioning hole corresponding to the mounting hole. The stabilizing member 202 may be fixed to the surface of the housing 201 by screws passing through the mounting hole 202a and the positioning hole.

[0047] It should be noted that in actual applications, the output terminals 203 must comply with corresponding safety regulations. That is, the size of each output terminal 203 and the distance between any two adjacent output terminals 203 must also comply with corresponding safety regulations. Therefore, the size of the multiple through-holes in the stabilizer 202 connected to the output terminals 203, as well as the spacing between any two adjacent through-holes in the stabilizer 202, must also match the size of the output terminals 203 and the distance between the two output terminals 203. For example, the spacing between any two adjacent through-holes in the stabilizer 202 can be greater than or equal to a preset safety distance.

[0048] The safety distance may be specified in the safety regulations for the power distribution unit. For example, if the safety distance is an electrical clearance, and the safety regulations require an electrical clearance of 14 millimeters (mm), then when the two output terminals 203 pass through the through holes of the stabilizer 202, the distance between the edge of one through hole and the edge of the other through hole may be 14 mm. Accordingly, the electrical clearance between the two output terminals 203 is also 14 mm.

[0049] In addition, in order to accommodate output terminals 203 of different sizes, the stabilizer 202 may also be provided with through holes of different sizes. The size of at least one through hole in the stabilizer 202 may be different from the sizes of other through holes in the stabilizer 202 .

[0050] Furthermore, the size of the stabilizer 202 can be adjusted. Figure 4 , Figure 4 A structural schematic diagram of another stabilizing member provided in an embodiment of the present application, wherein the volume of the stabilizing member 202 located inside the shell 201 may be smaller than the volume of the stabilizing member 202 located outside the shell 201, thereby forming a heat dissipation space in the space inside the shell 201 where the stabilizing member 202 is located, so as to improve the heat dissipation performance of the power distribution unit.

[0051] Moreover, the housing 201 can be provided with vents at the heat dissipation space, so that the heat dissipation effect can be further improved through the vents. When the power distribution unit is working, the output terminal 203 will continue to generate heat, so that the air flowing through the vents can be used to dissipate heat to the power distribution unit.

[0052] Furthermore, the power distribution unit may further include a heat shrink tube. Sleeving the heat shrink tube on the output terminals 203 can further improve the insulation effect between the output terminals 203, thereby further improving the safety of the power distribution unit.

[0053] It should be noted that the embodiment of the present application is described with only one power distribution board 204 as an example, but in actual applications, the power distribution unit may also include multiple power distribution boards 204. Figure 5 , Figure 5 A structural schematic diagram of another power distribution unit provided in an embodiment of the present application, wherein a power distribution plate 203 can be symmetrically provided on the upper surface and the lower surface of the output terminal 203, respectively, thereby reducing the area occupied by each power distribution plate 203, thereby reducing the area occupied by the power distribution unit.

[0054] In summary, the power distribution unit proposed in the embodiment of the present application is configured by disposing output terminals, a power distribution board, and a switch array within a housing, and clamping a stabilizing member onto the surface of the housing through a through hole of the housing. One end of the output terminal can be connected to the stabilizing member, and a switch array corresponding to the power distribution board can be provided on the side of the power distribution board away from the output terminal. The switch array is connected to the output terminal via a metal connector. By disposing a stabilizing member within the housing, connecting the output terminal to the stabilizing member, and fixing each output terminal via the stabilizing member, the stability of the output terminal in the power distribution unit can be improved, thereby improving the reliability and safety of the power distribution unit.
