[0026] In an aspect of the present application, an electric drive controller 10 of a vehicle is provided. The electric drive controller 10 comprises a filtering assembly 11, a capacitor assembly 12, a control mainboard 13, a copper bar assembly 14 and a first housing 17. The filtering assembly 11, the capacitor assembly 12 and the control mainboard 13 are arranged along a first direction X, the capacitor assembly 12 is located between the filtering assembly 11 and the control mainboard 13, the control mainboard 13 and the copper bar assembly 14 are arranged along a second direction Y, the first direction X and the second direction Y are perpendicular to each other, the first housing 17 is provided with a receiving cavity 182 and a second opening 181 communicating with the receiving cavity 182, the filtering assembly 11, the capacitor assembly 12, the control mainboard 13 and part of the copper bar assembly 14 are arranged in the receiving cavity 182, and a projection of the copper bar assembly 14 along the first direction X covers at least part of the receiving cavity 182.

[0027] According to the above structure, the receiving cavity 182 can provide a receiving space for the filtering assembly 11, the capacitor assembly 12, the control mainboard 13 and part of the copper bar assembly 14. The filtering assembly 11, the capacitor assembly 12 and the control mainboard 13 are arranged along the first direction X, and the control assembly and the copper bar assembly 14 are arranged along the second direction Y, and the first direction X and the second direction Y are perpendicular to each other. The arrangement direction of the filtering assembly 11, the capacitor assembly 12 and the control mainboard 13 is perpendicular to the arrangement direction of the control mainboard 13 and the copper bar assembly 14. The projection of the copper bar assembly 14 along the first direction X covers at least part of the receiving cavity 182. The copper bar assembly 14 extends along the side edge of the first housing 17 and shares the space extending along the second direction Y with the first housing 17. Therefore, the overall volume of the electric drive controller 10 can be reduced, the structure of the electric drive controller 10 is more compact, and the miniaturization of the electric drive controller 10 is achieved.

[0028] Further, the capacitor assembly 12 is arranged between the filtering assembly 11 and the control mainboard 13. In use, the positive and negative high-voltage currents of the battery pass through the filtering assembly 11 in sequence, enter the capacitor assembly 12, are stored in the capacitor assembly 12 and then input into the control mainboard 13, are converted from direct current to alternating current, and are then output to the motor. The capacitor assembly 12 can effectively filter and stabilize the current from the filtering assembly 11, and then transmit the stabilized current to the control mainboard 13. Therefore, the efficiency of the entire electric drive controller 10 can be improved. In addition, the capacitor assembly 12 can reduce the burden of the control mainboard 13, so as to prevent the control mainboard 13 from being damaged due to excessive current impact. Therefore, the service life of the control mainboard 13 can be improved, and the reliability of the electric drive controller 10 is improved.

[0029] The capacitor assembly 12 can be electrically connected to the control mainboard 13 and the filtering assembly 11 through power lines, or the capacitor assembly 12 can be electrically connected to the control mainboard 13 and the filtering assembly 11 through plug-in connection.

[0030] Please continue to refer to Figures 2 to 4 , Figure 3 is a partial structural schematic diagram of a control mainboard of an embodiment of the electric drive controller of the present application; Figure 4 is a structural schematic diagram of the copper bar assembly and the magnetic ring assembled together of an embodiment of the electric drive controller of the present application. In some embodiments of the present application, the control mainboard 13 comprises a driving circuit 133, a discrete Hall element 131 and a magnetic ring 132, the driving circuit 133 and the discrete Hall element 131 are located on the side of the control mainboard 13 close to the copper bar assembly 14, the magnetic ring 132 is located on the copper bar assembly 14, and the sensing part of the discrete Hall element 131 is located at the first opening 1321 of the magnetic ring 132. Therefore, the discrete Hall element 131 in the present application can be arranged separately from the magnetic ring 132. On the one hand, compared with integrated arrangement, the discrete arrangement can more reasonably optimize the system layout of the electric drive controller 10, so as to make the internal structure arrangement of the electric drive controller 10 more reasonable, thereby reducing the volume of the electric drive controller 10. On the other hand, by arranging the discrete Hall sensor and the magnetic ring 132 separately, the versatility of the electric drive controller 10 can be improved. For different models of electric drive units, only the corresponding discrete Hall element 131 needs to be replaced according to different measurement parameters, without changing the structure of the magnetic ring 132. Compared with replacing integrated Hall elements, the replacement cost is lower, and the platform degree is higher.

[0031] By arranging the sensing part of the discrete Hall element 131 at the first opening 1321 of the magnetic ring 132, the magnetic ring 132 can concentrate the magnetic field, so that the magnetic field environment of the discrete Hall element 131 is more stable and uniform, thereby effectively improving the detection accuracy of the discrete Hall element 131 to the magnetic field, so as to obtain more accurate measurement results. In addition, the influence of external interference on the discrete Hall element 131 can be reduced, so that the discrete Hall element 131 can maintain stable output, thereby improving the accuracy of the measurement results.

[0032] Among them, the control mainboard 13 further comprises IGBT (Insulated Gate Bipolar Transistor) and current sensor, etc., to invert direct current to alternating current.

[0033] In some embodiments of the present application, the control mainboard 13 further comprises a Hall auxiliary circuit (not shown in the figure) arranged on the other side of the control mainboard 13 away from the copper bar assembly 14, wherein the Hall auxiliary circuit is provided with a conductive shielding glue (not shown in the figure) on the surface away from the control mainboard 13. First, in the present application, the arrangement of the Hall auxiliary circuit can amplify, filter and process the output signal of the discrete Hall element 131, thereby improving the accuracy and stability of the output signal of the discrete Hall element 131, and further improving the measurement accuracy of the discrete Hall element 131. Secondly, by arranging the Hall auxiliary circuit on the other side of the control mainboard 13 away from the copper bar assembly 14, the discrete arrangement of the Hall auxiliary circuit, the Hall element and the magnetic ring 132 can be realized. On the one hand, compared with the integrated arrangement, the system layout of the electric drive controller 10 can be more reasonably optimized, the size of the discrete Hall element 131 in the height direction can be reduced, and the volume of the electric drive controller 10 can be reduced. On the other hand, the magnetic field generated around the Hall auxiliary circuit can also avoid interfering with the detection of the discrete Hall element 131, thereby improving the detection accuracy of the discrete Hall element 131.

[0034] Further, since the discrete Hall element 131, the magnetic ring 132 and the Hall auxiliary circuit are arranged separately, the anti-electromagnetic interference ability and the anti-temperature change ability of the discrete Hall element 131 are weak. By arranging the conductive shielding glue on the surface of the Hall auxiliary circuit away from the control mainboard 13, the signal distortion or misjudgment of the discrete Hall element 131 during the detection of the magnetic field can be avoided, and the anti-interference ability of the discrete Hall element 131 can be effectively improved to improve the detection accuracy of the discrete Hall element 131.

[0035] Please refer to Figure 2 Refer to Figure 4In some embodiments of the present application, the copper bar assembly 14 comprises a mounting seat 141 and a copper bar connecting piece 142; the copper bar connecting piece 142 is fixedly connected with the mounting seat 141, the first end of the copper bar connecting piece 142 extends along the first direction X, and the second end of the copper bar connecting piece 142 extends along the second direction Y. In the present application, the mounting seat 141 can play a role in mounting and fixing the copper bar connecting piece 142, and the copper bar connecting piece 142 can realize the electrical connection between the control mainboard 13 and the remaining structural members in the vehicle. Further, the first end is provided with a magnetic ring 132, and the first opening 1321 faces the control mainboard 13. On the one hand, the magnetic ring 132 is provided around the first end of the copper bar connecting piece 142, and can be separately provided with the discrete Hall element 131. Compared with the integrated arrangement, the internal structure layout of the electric drive controller 10 can be more reasonably optimized, thereby reducing the volume of the electric drive controller 10. On the other hand, the first opening 1321 faces the control mainboard 13, so that the sensing part of the discrete Hall element 131 can be located in the first opening 1321, and the magnetic field generated by the magnetic ring 132 is relatively stable, so that the magnetic field environment in which the discrete Hall element 131 is located can be more stable and uniform, thereby effectively improving the detection accuracy of the discrete Hall element 131 to the magnetic field, so as to obtain more accurate measurement results.

[0036] In some embodiments of the present application, the mounting seat 141, the copper bar connecting piece 142 and the magnetic ring 132 are integrally formed. By integrally forming, on the one hand, the connection stability between the magnetic ring 132 and the copper bar assembly 14 can be effectively improved, thereby improving the reliability of the electric drive controller 10; on the other hand, integrally forming can make the copper bar connecting piece 142, the mounting seat 141 and the magnetic ring 132 be closely connected, thereby reducing the space interval and connecting components therebetween, so that the volume of the whole formed by the mounting seat 141, the copper bar connecting piece 142 and the magnetic ring 132 is smaller, and the weight is lighter, thereby improving the space utilization rate inside the electric drive controller 10. In addition, since the three are integrally formed, when the electric drive controller 10 is assembled, the copper bar assembly 14 and the magnetic ring 132 do not need to be assembled again, thereby reducing the assembly time and improving the production efficiency.

[0037] Of course, in some other embodiments, the mounting seat 141, the copper bar connecting piece 142 and the magnetic ring 132 can also be connected by a connecting piece, which is not limited here.

In the present application, the arrangement of the protection piece 15 can prevent the discrete Hall element 131 from being damaged by knocking during transportation, thereby prolonging the service life of the discrete Hall element 131. By extending the end of the protection piece 15 away from the control mainboard 13 to the first opening 1321, the induction part of the discrete Hall element 131 can be protected, so as to avoid the influence of knocking on the detection accuracy of the discrete Hall element 131, thereby improving the detection accuracy of the discrete Hall element 131 by protecting the induction part.

[0039] The protection piece 15 can be fixedly connected with the control mainboard 13 by welding, or can be fixedly connected with the control mainboard 13 by a connecting piece, which is not limited here. In addition, a foolproof mark can be arranged at the pin of the protection piece 15 to improve the installation success rate and efficiency of the protection piece 15.

[0040] The protection piece 15 is highly adaptable and can also adapt to discrete Hall elements 131 of different specifications.

[0041] In some embodiments of the present application, the electric drive controller 10 further comprises a shielding piece 16; the shielding piece 16 is located on the side of the control mainboard 13 away from the copper bar assembly 14. In the present application, the arrangement of the shielding piece 16 can effectively prevent electromagnetic interference, thereby improving the safety and stability of the electric drive controller 10 in a high-voltage environment. In addition, the arrangement of the shielding piece 16 can also facilitate heat dissipation of the electric drive controller 10, thereby improving the heat dissipation efficiency of the electric drive controller 10.

[0042] In some embodiments of the present application, the end faces of the filter assembly 11 and the capacitor assembly 12 in the second direction Y, and the end faces of the shielding piece 16 and part of the control mainboard 13 away from the copper bar assembly 14 are flush in the second direction Y. The above arrangement, the filter assembly 11, the capacitor assembly 12, the shielding piece 16 and the control mainboard 13 are not protruding outward, which not only can reduce the volume of the electric drive controller 10, but also can improve the aesthetic appearance of the electric drive controller 10. In addition, the flush arrangement can also make the filter assembly 11 and the capacitor assembly 12 closely cooperate, and the shielding piece 16 and the control mainboard 13 closely cooperate, so that the design of the electric drive controller 10 can be more compact, thereby improving the integration and reliability of the electric drive controller 10.
