Conventional copper busbars are usually long conductors with rectangular or chamfered (rounded) rectangular cross-sections. However, the existing all-in-one controllers have complex internal structures and limited space. The use of conventional copper busbars not only takes up a large space, but also cannot avoid some modules, which is easy to cause electromagnetic interference. Summary of the invention

DETAILED DESCRIPTION
[0019] The specific implementation of the present invention is described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.
[0020] Embodiment 1:
[0021] like Figure 1 As shown, a special-shaped copper busbar 1 for an all-in-one controller includes a copper busbar body, which includes a main board 11, a first mounting plate 12 and a second mounting plate 13. The two ends of the main board 11 are bent once to form the first mounting plate 12 and the second mounting plate 13, and the bending directions of the first mounting plate 12 and the second mounting plate 13 are different.
[0022] like Figure 1As shown, specifically, a first mounting plate 12 and a second mounting plate 13 are respectively vertically provided at both ends of the upper side wall of the mainboard 11, the first mounting plate 12 extends toward the front end of the mainboard 11, and the second mounting plate 13 extends toward the rear end of the mainboard 11. The first mounting plate 12 and the second mounting plate 13 are both provided with mounting screw holes for easy connection with other copper busbar components or control modules.
[0023] like Figure 1 As shown, the corners of the entire copper busbar body are all provided with arc chamfers, and the angles between the first mounting plate 12 and the second mounting plate 13 and the main board 11 are arc-shaped transitions, thereby effectively avoiding the generation of tip discharge.
[0024] like Figure 1 and Figure 2 As shown, an all-in-one controller includes a control box 2, in which an MCU module 21, a low-voltage control socket 22, a three-phase electrical connector 23, and a first copper bar assembly, a second copper bar assembly, and a third copper bar assembly are arranged. The low-voltage control socket 22 is arranged above the MCU module 21, and the three-phase electrical connector 23 is arranged beside the MCU module 21. The IGBT module of the MCU module 21 is connected to the U phase, V phase, and W phase of the three-phase electrical connector through the first copper bar assembly, the second copper bar assembly, and the third copper bar assembly, respectively. The first copper bar assembly includes a special-shaped copper bar 1 and a conventional L-shaped copper bar 25 that match each other, and the second copper bar assembly and the third copper bar assembly both include conventional straight copper bars 24 and L-shaped copper bars 25 that match each other. A yielding portion for avoiding the low-voltage control socket 22 is formed between the first mounting plate 12 and the second mounting plate 13 of the special-shaped copper bar 1.
[0025] like Figure 1 and Figure 2 As shown, since a low-voltage control socket 22 is provided between the IGBT module and the U phase of the three-phase electrical connector 23, if a conventional straight copper busbar 24 is used, it is impossible to avoid the low-voltage control socket 22 and it is easy to cause electromagnetic interference. However, the special-shaped copper busbar 1 provided in this embodiment can be connected to the L-shaped copper busbar 25 around the outside of the low-voltage control socket 22, thereby cleverly avoiding the low-voltage control socket 22.
[0026] Embodiment 2:
[0027] like Figure 3 As shown, a special-shaped copper busbar 1 for an all-in-one controller includes a copper busbar body, which includes a main board 11, a first mounting plate 12 and a second mounting plate 13. The two ends of the main board 11 are bent twice to form the first mounting plate 12 and the second mounting plate 13, and the bending directions of the first mounting plate 12 and the second mounting plate 13 are opposite.
[0028] like Figure 3As shown, specifically, the first mounting plate 12 includes a first vertical plate 121 and a first horizontal plate 122, the first vertical plate 121 is vertically arranged on the left side wall of the main board 11, and the first horizontal plate 122 is vertically arranged on the upper side wall of the first vertical plate 121 and extends toward the left side of the main board 11; the second mounting plate 13 includes a second vertical plate 131 and a second horizontal plate 132, the second vertical plate 131 is vertically arranged on the right side wall of the main board 11, and the second horizontal plate 132 is vertically arranged on the upper side wall of the second vertical plate 131 and extends toward the front end of the main board 11. Both the first horizontal plate 122 and the second horizontal plate 132 are provided with mounting screw holes, which are convenient for connecting with other copper busbar components or control modules.
[0029] like Figure 3 As shown, the corners of the entire copper busbar body are all provided with arc chamfers, and the angles between the first mounting plate 12 and the second mounting plate 13 and the main board 11 are arc-shaped transitions, thereby effectively avoiding the generation of tip discharge.
[0030] like Figure 3 and Figure 4 As shown, an all-in-one controller includes a control box 1, a relay group 26, a fuse box 27 and a fourth copper bar assembly arranged in the control box, the relay group 26 is arranged horizontally on the inner wall of the control box 1, the fuse box 27 is arranged on the outer wall of the control box 1, and the control box 1 is also provided with a connection port connected to the power battery directly opposite the relay group 26, and the connection port is connected to the fuse box 27 through the fourth copper bar assembly. The fourth copper bar assembly includes a conventional straight copper bar 24 and a special-shaped copper bar 1 provided in this embodiment, and a yielding portion for avoiding the relay group 26 is formed between the first mounting plate 12 and the second mounting plate 13 of the special-shaped copper bar 1.
[0031] like Figure 3 and Figure 4 As shown, since a relay group 26 is provided between the connection port of the power battery and the fuse box 27, if a conventional straight copper busbar 24 or an L-shaped copper busbar 25 is used here, the relay group 26 cannot be avoided and electromagnetic interference is easily caused. However, the special-shaped copper busbar 1 provided in this embodiment can be connected to the fuse box 27 around the outside of the relay group 26, thereby cleverly avoiding the relay group 26.
[0032] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
