[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] It should be noted that the high-voltage connection module of the motor controller in the embodiment of the present utility model is generally used in the motor controller for new energy vehicles.

[0026] like Figures 1 to 5 As shown, an embodiment of the present invention provides a high-voltage wiring module for a motor controller. The high-voltage wiring module for the motor controller includes: a wiring base 19; multiple input copper busbars 11 disposed on the wiring base 19; multiple output copper busbars 12 disposed on the wiring base 19; and a filtering component disposed on the wiring base 19. The filtering component includes an EMC filter board 13 and an EMC magnetic ring 14. The EMC magnetic ring 14 is located on the periphery of the multiple input copper busbars 11, and the EMC filter board 13 is electrically connected to the multiple input copper busbars 11.

[0027] In the above technical solution, by setting the EMC filter board 13 and the EMC magnetic ring 14, the common-mode interference and differential-mode interference in the circuit can be suppressed, thereby effectively improving the EMC level of the motor controller. It can not only avoid interference with other electronic equipment, but also prevent the influence of external electromagnetic interference on the motor controller, so as to ensure that the motor controller can work normally in a complex electro-EMC magnetic environment.

[0028] Furthermore, the EMC filter board 13 and the EMC magnetic ring 14 are integrated into one, which can save space.

[0029] It should be noted that, in the embodiment of the present invention, the EMC magnetic ring 14 can suppress common-mode interference in the circuit. The EMC magnetic ring 14 converts common-mode interference energy into heat energy through the hysteresis loss and eddy current loss of its magnetic material.

[0030] It should be noted that in the embodiments of the present invention, the EMC ferrite bead and the EMC filter board are both components of the EMC filter, wherein the EMC filter board generally refers to a filter arranged on a circuit board, which may be a surface mounted filter or a filter circuit integrated on a circuit board, and the EMC filter board includes corresponding Y capacitors.

[0031] Preferably, in an embodiment of the present invention, there are two input copper bars 11, one for the DC positive pole and one for the DC negative pole. Both input copper bars 11 pass through an EMC magnetic ring for DC current filtering. Three output copper bars 12 are used for AC three-phase U / V / W outputs. This allows the motor controller to input DC power and output AC power.

[0032] like Figure 2 and Figure 3 As shown, in the embodiment of the present invention, a mounting hole 15 is provided on the wiring base 19, multiple input copper bars 11 are passed through the mounting hole 15, and the EMC magnetic ring 14 is fixed to the mounting hole 15. In this way, the multiple input copper bars 11 and the EMC magnetic ring 14 can be supported and positioned.

[0033] like Figure 3As shown, in an embodiment of the present invention, the high-voltage wiring module of the motor controller further includes a packaging material, which is filled in the mounting through-hole 15. The EMC magnetic ring 14 and the plurality of input copper busbars 11 are fixed to the terminal block 19 via the packaging material. In this way, the EMC magnetic ring 14 can be fixed in the mounting through-hole 15 by the packaging material, and the packaging material can also fix the input copper busbars 11 to the terminal block 19, so that the input copper busbars 11 and the EMC magnetic ring 14 can form an integrated structure with the terminal block 19, further reducing space and facilitating installation and maintenance.

[0034] Preferably, in an embodiment of the present invention, the packaging material can be filled into the mounting through hole 15 provided with the EMC magnetic ring 14 and multiple input copper busbars 11 by means of glue injection or potting. After the packaging material is cured, the input copper busbar 11 and the EMC magnetic ring 14 can be fixed on the terminal block 19.

[0035] Preferably, in the embodiment of the present invention, the plurality of output copper bars 12 are fixed to the wiring base 19 by screws, and may also be fixed to the wiring base 19 by injection molding, potting, or the like.

[0036] like Figure 2 and Figure 3 As shown, in the embodiment of the present invention, the mounting through hole 15 includes a first hole section 151 and a plurality of second hole sections 152 connected to the first hole section 151. The plurality of second hole sections 152 are spaced apart in a direction perpendicular to the axis of the second hole section 152. The EMC magnetic ring 14 is located in the first hole section 151. The plurality of input copper bars 11 extend into the plurality of second hole sections 152 respectively through the first hole section 151.

[0037] Through the above arrangement, on the one hand, the EMC magnetic ring 14 is arranged in the first hole section 151, which can position the EMC magnetic ring 14 and ensure that the EMC magnetic ring 14 can effectively filter common-mode interference when the input copper busbar 11 passes through it, thereby significantly improving the EMC level of the controller and reducing the impact of electromagnetic interference on the system; on the other hand, the multiple second hole sections 152 are arranged at intervals along a direction perpendicular to the axis of the second hole section 152. In this way, the multiple input copper busbars 11 can be respectively extended into different second hole sections 152, which not only saves space but also avoids direct contact between the multiple input copper busbars 11, thereby contributing to electrical isolation and safety.

[0038] like Figure 1 As shown, in an embodiment of the present invention, the EMC filter board 13 is correspondingly arranged above multiple input copper bars 11, and the high-voltage wiring module of the motor controller also includes a locking piece 16, and the EMC filter board 13 is fixed to the wiring seat 19 through the locking piece 16.

[0039] Through the above arrangement, on the one hand, the EMC filter board 13 is directly arranged above the input copper bus 11, which can utilize the vertical space, thereby avoiding the redundant space occupied by the traditional horizontal layout. In this way, the structure of the entire motor controller can be made more compact, thereby saving installation space; on the other hand, the locking member 16 can ensure a firm connection between the EMC filter board 13 and the terminal block 19, thereby improving the structural stability of the entire high-voltage wiring module and the electrical contact reliability between components.

[0040] Preferably, in the embodiment of the present invention, the locking member 16 is a screw.

[0041] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, each input copper busbar 11 has an input end and an output end that are oppositely arranged, and each output copper busbar 12 has an input portion and an output portion that are oppositely arranged, and the input end and the output portion are located on the same side of the wiring seat 19.

[0042] Through the above arrangement, on the one hand, the input copper busbar 11 and the output copper busbar 12 are integrated on the terminal block 19, and the input end of the input copper busbar 11 and the output part of the output copper busbar 12 are arranged on the same side of the terminal block 19, so that a more efficient component layout can be achieved in a limited space, thereby making the overall layout of the high-voltage integrated wiring module more compact, so as to reduce the volume and weight of the motor controller, which can not only reduce the installation space of the motor controller on the vehicle, but also help to improve the power density of the motor controller; on the other hand, it can reduce the complexity of wiring, make on-site installation and maintenance more convenient, thereby improving the efficiency of installation and maintenance.

[0043] like Figure 1 As shown, in an embodiment of the present invention, the high-voltage wiring module of the motor controller further includes: a support member 17, which is arranged above the wiring seat 19; a limit switch 18, which is installed on the side of the support member 17 away from the wiring seat 19, and the limit switch 18 is constructed to be able to contact the cover plate of the motor controller, and the limit switch 18 is configured to be electrically connected to the control unit of the motor controller.

[0044] Through the above-mentioned setting, the limit switch 18 can be in contact with the cover of the motor controller. When the cover of the motor controller is opened, the limit switch 18 will be activated to realize the cover opening protection function, thereby effectively preventing the risk of electric shock caused by the motor controller cover not being closed during maintenance or inspection, thereby improving the safety of the operator.

[0045] Furthermore, integrating the travel switch 18 on the terminal block 19 can reduce the number of components, improve integration, and save costs.

[0046] It should be noted that, in the embodiment of the present invention, the control unit of the motor controller is a control circuit board.

[0047] Specifically, in the embodiment of the present invention, the support member 17 is made of an insulating material and is located between the multiple input copper bars 11 and the multiple output copper bars 12. Thus, the support member 17 is provided between the input copper bars 11 and the output copper bars 12 to effectively isolate the DC power from the AC power.

[0048] Preferably, in the embodiment of the present invention, the support member 17 is a support column.

[0049] Specifically, in the embodiment of the present invention, the wiring base 19 is made of an insulating material. In this way, the insulation property of the wiring base 19 can effectively isolate direct current and alternating current, isolate the electrical distance, and thus enhance electrical safety performance.

[0050] It should be noted that, in the embodiment of the present invention, the overall structural arrangement of the high-voltage connection module 10 of the motor controller is reasonable, and the overall modular design is convenient for installation.

[0052] Preferably, in the embodiment of the present invention, the high-voltage connection module 10 of the motor controller is fixed in the housing 20 by screws.

[0053] like Figure 4 As shown, in an embodiment of the present invention, the automobile drive motor controller further includes a plurality of input connectors 30, which are arranged corresponding to the plurality of input copper busbars 11, with one end of each input connector 30 connected to the corresponding input copper busbar 11, and the other end of each input connector 30 extending out of the housing 20; and / or, the automobile drive motor controller further includes a plurality of output connectors 40, which are arranged corresponding to the plurality of output copper busbars 12, with one end of each output connector 40 connected to the corresponding output copper busbar 12, and the other end of each output connector 40 extending out of the housing 20. In this way, each input connector 30 and each output connector 40 extends out of the housing 20, and the interface positions are arranged reasonably, which makes the connection of external power cables more convenient. Wiring can be completed without opening the housing 20, which can simplify the installation and maintenance process, thereby improving work efficiency.

[0054] It should be noted that, in the embodiment of the present invention, the external power cable is conducted to the capacitor via the input copper bus 11 through the plurality of input connectors 30 .
