[0021] Explanation of reference numerals in the attached drawings: base (11), MOS circuit board (12), support pad (13), vertical section (131), horizontal section (132), main circuit board (14), support bar (111), positioning post (112), female connector (121), male connector (141), mounting hole (131), electric vehicle controller (2), top cover (21), heat sink (113), mounting flange (114). Detailed Implementation

[0022] like Figure 1As shown, a main circuit board support structure for an electric vehicle controller includes a base (11) and a MOS circuit board (12) securely connected to the base (11). A support pad (13) is disposed on the MOS circuit board (12) and is in contact with the MOS circuit board (12). The main circuit board (14) is electrically connected to the MOS circuit board (12) and is disposed above the support pad (13). A support strip (111) is provided on the inner wall of the base (11), and the main circuit board (14) is positioned by the support strip (111). The support strip (111) provides a stable support foundation for the main circuit board (14), ensuring that the main circuit board (14) maintains a fixed position during controller operation, and avoiding displacement of the main circuit board (14) due to vibration or other external forces, which would affect the stability of the electrical connection and the performance of the controller.

[0023] To enhance the stability of the main circuit board (14) in the length direction, a support bar (111) extends along the length of the base (11), reducing the risk of deformation or damage to the main circuit board (14) due to uneven stress.

[0024] Two positioning posts (112) are vertically arranged on one side of the support bar (111). The positioning posts (112) can further precisely define the position of the main circuit board (14). Together with the support bar (111), they can position the main circuit board (14) from multiple directions, which improves the accuracy and stability of the installation of the main circuit board (14), ensures the positional accuracy of the main circuit board (14) in the base (11), and is conducive to the reliability of electrical connections.

[0025] Multiple positioning posts (112) are vertically arranged on the inner wall. The multiple positioning posts (112) position and support the main circuit board (14) from multiple angles, further enhancing the stability of the main circuit board (14) in the base (11), preventing the main circuit board (14) from shaking in all directions, improving the stability of the entire support structure, and ensuring the reliable operation of the electric vehicle controller.

[0026] The MOS circuit board (12) is provided with a female connector (121), and the main circuit board (14) is provided with a male connector (141). The female connector (121) is connected to the male connector (141). This plug-in electrical connection method makes the electrical connection between the main circuit board (14) and the MOS circuit board (12) more convenient and faster. It also facilitates disassembly and installation when the circuit board needs to be repaired or replaced, thus improving the maintainability of the controller.

[0027] The screw passes through the MOS circuit board (12) and is fastened to the base (11). The support pad (13) is T-shaped, and the horizontal section of the support pad (13) has a mounting hole (131), which is fitted on the outside of the screw. The design of the T-shaped support pad (13) not only provides good support for the main circuit board (14), but also the cooperation between the mounting hole (131) on its horizontal section and the screw allows the support pad (13) to be stably fixed on the MOS circuit board (12), preventing the support pad (13) from shifting during use and ensuring the stability of the support for the main circuit board (14).

[0028] like Figure 2 and Figure 4 As shown, the support pad (13) also has a vertical section (131), which extends along the width direction of the base (11). The main body of the main circuit board (14) is supported by the horizontal section (132) of the support pad (13), one side of the main circuit board (14) in the width direction is supported by the vertical section (131) of the support pad (13), and one side of the main circuit board (14) in the length direction is supported by the positioning post (112) and the support bar (111). This all-round support method supports and positions the main circuit board (14) from different directions, fully ensuring the stability of the main circuit board (14) in the base (11), effectively reducing the shaking of the main circuit board (14) caused by vibration or external force, and improving the overall stability and reliability of the electric vehicle controller.

[0029] like Figure 5 As shown, an electric vehicle controller (2) includes the busbar arrangement structure described above, and also includes a top cover (21), which is connected to the base (11) by screws. The connection between the top cover (21) and the base (11) not only provides protection for the circuit boards and other components inside the electric vehicle controller (2) to prevent damage from external factors such as dust and moisture, but also enhances the overall structural strength of the controller and improves its impact resistance.

[0030] like Figure 3 As shown, a heat dissipation fin (113) is provided on the lower side of the base (11). The heat dissipation fin (113) can effectively increase the contact area between the base (11) and the air, improve the heat dissipation efficiency, and dissipate the heat generated by the MOS circuit board (12) and the main circuit board (14) during operation in a timely manner, preventing the circuit board from degrading or being damaged due to overheating, and extending the service life of the electric vehicle controller (2).

[0031] Mounting flanges (114) are provided on both sides of the base (11). The mounting flanges (114) enable the electric vehicle controller (2) to be easily installed in a specific position on the electric vehicle. By connecting the mounting flanges (114) to the corresponding mounting parts on the electric vehicle, the convenience and stability of the installation are improved, ensuring that the electric vehicle controller (2) can be firmly fixed in the required position during the operation of the electric vehicle.
