These devices include power distribution units that can connect to multiple charging terminals (such as charging piles) to distribute power among them. In related technologies, the power distribution unit includes a scheduling block and outgoing conductors. The scheduling block has these conductors; some are used solely for scheduling, while others serve both scheduling and have incoming connection points for connecting to incoming lines. Similarly, in the outgoing conductors, some are used only for connecting to outgoing lines, while others serve both. This results in a complex structure with various types of conductors within the power distribution unit, and wiring positions mixed between the scheduling area and the outgoing conductors, making wiring difficult.

[0040] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] In the description of the embodiments of this application, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," and "third" may explicitly or implicitly include one or more of that feature.

[0042] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, "linking" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0043] In the description of embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0044] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a power distribution unit.

[0045] like Figure 1 As shown, the power distribution unit includes incoming line connection parts ①, ②, ... Outgoing connection parts M1, M2, ..., M12, and scheduling block.

[0046] The incoming and outgoing cable connections can be connected one-to-one. For example, see [link to relevant documentation]. Figure 1 The incoming line connection part ① and the outgoing line connection part M12 are connected accordingly; the incoming line connection part ② and the outgoing line connection part M2 are connected accordingly; the incoming line connection part ③ and the outgoing line connection part M9 are connected accordingly; the incoming line connection part ④ and the outgoing line connection part M4 are connected accordingly; the incoming line connection part ⑤ and the outgoing line connection part M10 are connected accordingly; the incoming line connection part ⑥ and the outgoing line connection part M6 are connected accordingly; the incoming line connection part ⑦ and the outgoing line connection part M11 are connected accordingly; the incoming line connection part ⑧ and the outgoing line connection part M8 are connected accordingly; the incoming line connection part ⑨ and the outgoing line connection part M1 are connected accordingly; the incoming line connection part ⑩ and the outgoing line connection part M3 are connected accordingly; the incoming line connection part... Connect to the outgoing line connector M5, and the incoming line connector. Connect it to the corresponding outgoing cable connection part M7.

[0047] The scheduling block includes switching components, which can be, for example, relays, contactors, etc. Combined with... Figure 1 The scheduling block can include a ring section (red line), a bridging section (blue line), and a branch section (green line), each connected to a switching component. In practical applications, by controlling the opening and closing of each switching component in the scheduling block, the output power of different outgoing line connections can be adjusted, thereby achieving power distribution.

[0048] In detail, taking the incoming line connection part ① and the outgoing line connection part M12 as examples, the outgoing line connection part M12 can only receive power input from the incoming line connection part ①; or, when the outgoing line connection part M1 does not need to output, the switch component connecting the branch of the incoming line connection part ① and the incoming line connection part ⑨ can be closed to simultaneously introduce power input from the incoming line connection part ⑨. In this case, the outgoing line connection part M12 can have a relatively large power output.

[0049] The aforementioned scheduling block includes not only switching components but also a large number of conductive busbars for connecting the various switching components. The incoming and outgoing connection sections are also located on these conductive busbars. Therefore, the total number of conductive busbars involved in the entire power distribution unit is relatively large. In this embodiment, the conductive busbars mainly refer to copper busbars, aluminum busbars, etc.

[0050] It can be seen that the above description of the number of incoming and outgoing connection parts is mainly based on... Figure 1 The illustration does not necessarily limit the number of incoming and outgoing connection parts. In practical applications, the number of incoming and outgoing connection parts of the power distribution unit can also be set to other numbers, as long as the requirements of use are met.

[0051] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a power distribution unit in related technologies.

[0052] In related technologies, the incoming line connection parts ①, ②, ... The arrangement of the items is relatively scattered. For example, see [link to relevant documentation]. Figure 2 The incoming line connection parts ①, ②, ③, ④, ⑤, and ⑦ are respectively installed on the conductive bars of the ring-shaped part (red arrow) used to form the dispatching block, and the incoming line connection parts ⑥, ⑧, ⑨, and ⑩ are respectively installed on the conductive bars of the ring-shaped part (red arrow). , Furthermore, these connections can be installed on the conductive busbars used for setting outward connection points, resulting in a wide variety of conductive busbars that are difficult to identify and install, severely impacting assembly efficiency. Taking a ring-shaped section as an example, some conductive busbars require inward connection points, while others do not. Even for conductive busbars with inward connection points, the structural form may differ depending on the installation location of the switching element to be connected. Moreover, since both the conductive busbars in the dispatching block and those with outward connection points may have inward connection points, inward connections are required in different areas of the entire power distribution unit, resulting in a relatively complex wiring structure that is detrimental to installation and maintenance.

[0053] In summary, due to the unreasonable structural design of the power distribution unit in related technologies, the power distribution unit suffers from technical defects that make wiring difficult during use, which seriously affects the normal use, disassembly, and maintenance of the power distribution unit.

[0054] Please refer to Figures 3-5 , Figure 3 This is a schematic diagram of the structure of a power distribution unit provided in an embodiment of this application; Figure 4 for Figure 3 A connection structure diagram of a wiring busbar, a transition busbar, an internal busbar, and a first support body; Figure 5 for Figure 3 Top view.

[0055] like Figure 3 and Figure 5 As shown, this application embodiment provides a power distribution unit 100, including a scheduling module 1000 and a wiring module 2000. The scheduling module 1000 is disposed in a first region A, and the wiring module 2000 is disposed in a second region B. The first region A and the second region B are different, so that the scheduling module 1000 and the wiring module 2000 can be arranged in different regions respectively. The approximate distribution positions of the first region A and the second region B can be referred to... Figure 5 The area enclosed by a double-dotted line.

[0056] The scheduling module 1000 includes a scheduling circuit 1100 and at least two switching components 1200, all of which are connected to each other. The wiring module 2000 includes at least two wiring busbars 2100, each of which is connected to the scheduling module 1000. Each wiring busbar 2100 has an inlet connection portion 2110 and an outlet connection portion 2120. The scheduling circuit 1100 and the switching components 1200 cooperate to enable connection or disconnection between the outlet connection portion 2120 and different inlet connection portions 2110, thereby achieving power distribution.

[0057] In this embodiment, a modular design concept is adopted, with the scheduling module 1000 and wiring module 2000 designed and installed in separate areas. The scheduling module 1000 includes a scheduling circuit 1100 and a switching component 1200, primarily used for power distribution. The wiring module 2000's wiring busbar 2100 is provided with an inlet connection 2110 and an outlet connection 2120, allowing the inlet and outlet lines of the power distribution unit 100 provided in this embodiment to be integrated into the wiring module 2000 for installation. This results in high integration and a relatively simple inlet and outlet line structure, facilitating easy installation, disassembly, inspection, and maintenance of the inlet and outlet lines.

[0058] Furthermore, since neither the incoming nor outgoing lines need to be connected to the scheduling module 1000, they can be relatively far away from the switching component 1200, and thus relatively far away from the control lines of the switching component 1200 itself. This reduces mutual interference or accidental contact between the incoming, outgoing, and control lines, and also helps ensure the safe and reliable operation of the power distribution unit 100. Simultaneously, it reduces the cutting and wear caused by the conductive busbars within the scheduling module 1000 on the incoming and outgoing lines, and also helps ensure the structural integrity and service life of the incoming and outgoing lines. This is also of relatively positive significance for ensuring the safe and reliable operation of the power distribution unit 100.

[0059] Furthermore, since the wiring busbar 2100 is mainly used to connect with the incoming and outgoing lines, it participates less in the formation of the scheduling circuit 1100, allowing for a relatively simple and uniform structural design. Similarly, the busbars in the scheduling module 1000, which do not need to connect with the incoming lines, can also have a relatively uniform structural design. This also reduces the types of busbars required, facilitating production and installation and improving assembly efficiency.

[0060] Please continue to refer to this. Figure 3 In this embodiment of the application, the power distribution unit 100 may further include a support platform 3000.

[0061] Both the scheduling module 1000 and the wiring module 2000 can be directly or indirectly mounted on the support platform 3000 for integrated assembly, thereby improving the integration level of the power distribution unit 100 provided in this embodiment. Simultaneously, the support platform 3000 can also serve as a connecting component for the power distribution unit 100, allowing it to be installed and fixed during installation.

[0062] The support platform 3000 may have a support surface 3100, on which each switch component 1200 may be directly mounted. Along the normal direction of the support surface 3100, the projection of the support platform 3000 may be approximately rectangular, and the support platform 3000 may have a length direction X and a width direction Y. The scheduling module 1000 and the wiring module 2000 may be arranged along the width direction Y, achieving a reasonable spatial distribution of the scheduling module 1000 and the wiring module 2000. The wiring conductors 2100 may be spaced apart along the length direction X.

[0063] In some implementations, such as Figure 3 and Figure 4As shown, the terminal block 2100 can be linear. In this case, the structure of the terminal block 2100 can be relatively simple, making it easier to manufacture. The inlet connection 2110 and the outlet connection 2120 can be two opposite ends of the terminal block 2100, respectively.

[0064] The conductive busbar 2100 has an extending direction P, which can form an angle with the supporting surface 3100, for example, 90 degrees. It should be understood that the extending direction P can also be parallel to the supporting surface 3100. When the extending direction P of the conductive busbar 2100 forms an angle with the supporting surface 3100, such as... Figure 3 As shown, the space occupied by each conductive busbar 2100 in the width direction Y can be relatively small, allowing for a smaller power distribution unit. Of course, when the extension direction P of the conductive busbar 210 is parallel to the support surface 3100, the conductive busbar 2100 can be arranged along either the width direction Y or the length direction X. When the conductive busbar 2100 is arranged along the width direction Y, compared to being arranged along the length direction X, the space occupied in the length direction X can be relatively smaller. This is more advantageous for arranging a larger number of conductive busbars 2100 along the length direction X, thus making fuller use of the space in the length direction X. It should be understood that the extension direction P can also be parallel to the support surface 3100, which is also feasible.

[0065] As can be seen, the shape of the terminal block 2100 is not limited to the straight type mentioned above; it can also adopt other structural forms, as long as they can meet the requirements of use. For example, the terminal block 2100 can also be L-shaped, etc.

[0066] The conductive busbar 2100 may also be provided with a support and fixing hole 2130. The conductive busbar 2100 can be connected to a support and fixing member (described in detail later) through the support and fixing hole 2130, thereby realizing the installation and fixing of the conductive busbar 2100, so as to improve the installation stability and reliability of the conductive busbar 2100.

[0067] In some implementations, such as Figure 3 and Figure 4 As shown, the scheduling circuit 1100 may include transition conductors 1120. The number of transition conductors 1120 may be the same as the number of wiring conductors 2100. Specifically, the scheduling circuit 1100 may be connected one-to-one with each transition conductor 1120 and each wiring conductor 2100.

[0068] Here, the embodiments of this application do not limit the specific structural form of the transfer bus 1120. In practice, those skilled in the art can determine it according to actual needs, as long as it meets the requirements of use. For example, see [link to relevant documentation]. Figure 4 The transition busbar 1120 may include a first plate 1121 and a second plate 1122 at an angle. The first plate 1121 may be directly connected to the switch component 1200, or it may be connected to other busbars in the scheduling circuit 1100 (equivalent to an indirect connection between the first plate 1121 and the switch component 1200). The second plate 1122 may be connected to the wiring busbar 2100. The specific connection methods can be bolt connections, etc. The angle between the first plate 1121 and the second plate 1122 may be 90 degrees, etc. Alternatively, the first plate 1121 may be a bent plate, including a first plate segment 1121A, a second plate segment 1121B, and a third plate segment 1121C connected in sequence. The first plate segment 1121A and the second plate segment 1121B form an angle, and the second plate segment 1121B and the third plate segment 1121C also form an angle. The technical advantages of this structural design will be explained later.

[0069] In some implementations, the scheduling module 1000 may also include a first support body 1300.

[0070] One end of the first support 1300 can be connected to the adapter busbar 1120, and the other end of the first support 1300 can be connected to the aforementioned support platform 3000. The connection methods can include screw connection, welding, etc. The first support 1300 provides support for the adapter busbar 1120, thereby improving the installation stability of the adapter busbar 1120.

[0071] The first support 1300 and the transition conductive bus 1120 can be assembled in a one-to-one correspondence, meaning the number of first support 1300 and transition conductive bus 1120 can be the same, and each transition conductive bus 1120 can be supported and assembled one-to-one with each first support 1300. Alternatively, the first support 1300 and the transition conductive bus 1120 can also be assembled in a one-to-many relationship, meaning one first support 1300 can support at least two transition conductive buses 1120, which is also feasible.

[0072] In some implementations, such as Figure 5 As shown, the scheduling circuit 1100 may include at least two internal conductive bars 1110. Each internal conductive bar 1110 can be connected to the switching component 1200. Furthermore, each internal conductive bar 1110 can at least form a ring loop 1100A to construct the structural form required for the scheduling circuit 1100.

[0073] Here, the embodiments of this application do not limit the specific structural form of the above-described ring circuit 1100A. In practical applications, those skilled in the art can design it according to specific needs, or they can refer to... Figures 3-5 The design is as shown. In short, it is sufficient to meet the usage requirements of the power distribution unit 100.

[0074] In this embodiment of the application, the ring loop 1100A may include a first ring segment 1100A1 ( Figure 5 The distribution area indicated by the solid red arrow in the middle) and the second ring segment 1100A2 ( Figure 5 (The distribution area indicated by the dashed red arrows in the text).

[0075] The first ring segment 1100A1 can be connected to each of the switching components 1200 to primarily establish the electrical connection between the switching components 1200. The two ends of the second ring segment 1100A2 can each be connected to two switching components 1200 to cooperate with the first ring segment 1100A1, forming a complete ring circuit 1100A. With this configuration, the switching components 1200 can be concentrated near the first ring segment 1100A1, allowing for a more compact structure. Consequently, the structural dimensions of the internal conductive busbars 1110 used to construct the first ring segment 1100A1 can be relatively small, reducing manufacturing costs. Furthermore, the switching components 1200 can support and fix the internal conductive busbars 1110 of the first ring segment 1100A1, improving the connection reliability of the internal conductive busbars 1110 of the first ring segment 1100A1.

[0076] The scheduling module 1000 may further include a second support 1400. One end of the second support 1400 can be connected to the inner conductive busbar 1110 of the second ring segment 1100A2, and the other end of the second support 1400 can be connected to the support platform 3000. The connection methods can be screw connection, welding, etc. Since the number of switching components 1200 connected to the inner conductive busbar 1110 of the second ring segment 1100A2 is relatively small, the support obtained by the second ring segment 1100A2 from the switching components 1200 is also relatively small. Based on this, this embodiment of the application also uses the aforementioned second support 1400 to provide support for the inner conductive busbar 1110 of the second ring segment 1100A2, thereby improving the installation stability of the inner conductive busbar 1110 of the second ring segment 1100A2.

[0077] Here, the embodiments of this application do not limit the number of internal conductive busbars 1110 included in the first ring segment 1100A1 and the second ring segment 1100A2. In practical applications, those skilled in the art can make adjustments according to specific needs, as long as the requirements of use are met. For example, the second ring segment 1100A2 may include only one internal conductive busbar 1110, or it may include at least two internal conductive busbars 1110.

[0078] In some implementations, each internal busbar 1110 can also form at least one bridging branch 1100B, and the two ends of the bridging branch 1100B can be connected to the ring loop 1100A respectively to construct the structural form required for the scheduling circuit 1100.

[0079] Furthermore, among the aforementioned transition busbars 1120, the transition busbar 1120 directly connected to the switching component 1200 can also form a branch circuit 1100C of the scheduling circuit 1100. The ring circuit 1100A, the bridging branch 1100B, and the branch circuit 1100C can jointly construct the structural form required by the scheduling circuit 1100.

[0080] like Figure 3 and Figure 4 As shown, some of the transition conductors 1120 can be connected to the inner conductor 1110 to indirectly connect to the switch component 1200. In this implementation, the first plate 1121 of the transition conductive bus 1120 may include a first plate segment 1121A, a second plate segment 1121B, and a third plate segment 1121C connected in sequence. The second plate segment 1121B may be bent relative to the first plate segment 1121A in the extension direction P, so that the second plate segment 1121B and the first plate segment 1121A may form an angle. The third plate segment 1121C may also be bent relative to the second plate segment 1121B in the extension direction P, so that the third plate segment 1121C and the second plate segment 1121B may form an angle. The first plate segment 1121A is used to be stacked and connected with the inner conductive bus 1110. The third plate segment 1121C is connected to the second plate 1122 and is used to be connected to the first support 1300. With this configuration, by bending the first plate 1121, the first plate 1121 can better adapt to the difference in installation height between the inner conductive bus 1110 and the first support 1300, thereby facilitating the connection between the first plate 1121, the inner conductive bus 1110, and the first support 1300.

[0081] Please refer to Figures 6-9 , Figure 6 This is a schematic diagram of the structure of a power distribution device provided in an embodiment of this application; Figure 7 for Figure 6 A magnified view of a portion of the image; Figure 8 for Figure 6 The front view shows a simplified representation of each power converter in the power conversion unit. Figure 9 This is a schematic diagram of the power transmission principle of a power distribution device provided in an embodiment of this application.

[0082] like Figure 6 and Figure 8 As shown, this application embodiment also provides a power distribution device 10, which can be, for example, a charging pile, for use in conjunction with a charging terminal in the form of a charging station. The power distribution device includes a power distribution unit 100, which can be the power distribution unit 100 involved in the aforementioned implementations.

[0083] In addition, the power distribution device 10 may also include a power conversion unit 200, a switching unit 300, and a cabinet 400. The power distribution unit 100, the power conversion unit 200, and the switching unit 300 may all be housed in the cabinet 400 for integrated assembly via the cabinet 400.

[0084] Combination Figure 9 The switching unit 300 can be located upstream of the power conversion unit 200. The switching unit 300 is used to connect to external AC power and is also connected to the power conversion unit 200, enabling the connection or disconnection of power transmission between the external AC power and the power conversion unit 200. The power conversion unit 200 can be located upstream of the power distribution unit 100 and can be connected to the power distribution unit 100. The power conversion unit 200 is used to convert AC power to DC power and to transmit the converted DC power to the power distribution unit 100 for power distribution. Here, "upstream" refers to the direction of current transmission; where A is upstream of B, specifically, current can flow from A to B.

[0085] The number of power distribution units 100 can be two. Both power distribution units 100 can be connected to the power conversion unit 200. The two power distribution units 100 are used to realize the distribution and output of DC positive and DC negative terminals respectively.

[0086] In some implementations, such as Figure 7 As shown, the power distribution device 10 may also include a support fixing member 500, which may be, for example, an insulator.

[0087] The cabinet 400 may include a support beam 410, and the wiring busbar 2100 may be connected to the support fastener 500, which in turn may be connected to the support beam 410. This allows for the installation and fixation of the wiring busbar 2100, ensuring greater reliability and stability during installation.

[0088] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
