[0086] Reference below Figure 1-Figure 34The motor controller 200 according to the embodiment of the present invention is described.

[0087] like Figures 1 to 34 As shown, the motor controller 200 according to the embodiment of the utility model includes: a capacitor 6 and a first conductive component 2; the capacitor 6 includes a capacitor body 61 and a terminal plate 62 connected to the capacitor body 61, the terminal plate 62 includes a first terminal plate 621 and a second terminal plate 622; the first conductive component 2 is used to connect an external power supply; the first conductive component 2 includes a first conductive row 21 and a second conductive row 22, the first conductive row 21 is connected to the first terminal plate 621, and the second conductive row 22 is connected to the second terminal plate 622, wherein, in the projection of a plane parallel to the terminal plate 62, an end of the first conductive row 21 away from the first terminal plate 621 and an end of the second conductive row 22 away from the second terminal plate 622 do not exceed the capacitor body 61.

[0088] like Figures 1 to 34 In a specific embodiment shown, the motor controller 200 includes: an electric control housing 9, a capacitor 6, a second conductive component 7 and a first conductive component 2; the capacitor 6 is arranged in the electric control housing 9, the capacitor 6 includes a capacitor body 61 and a terminal plate 62 connected to the capacitor body 61, the capacitor body 61 has a central hole, the terminal plate 62 includes a first terminal plate 621 and a second terminal plate 622, and the first terminal plate 621 and the second terminal plate 622 are both located at the central hole; the second conductive component 7 is arranged on the housing cover 51, the second conductive component 7 includes a third conductive bar 71 and a fourth conductive bar 72; the first conductive component 2 includes a first conductive bar 21 and a second conductive bar 22, the two ends of the first conductive bar 21 are respectively connected to the first terminal plate 621 and the third conductive bar 71, and the two ends of the second conductive bar 22 are respectively connected to the second terminal plate 622 and the fourth conductive bar 72, wherein, in the projection of the plane parallel to the terminal plate 62, one end of the first conductive bar 21 away from the first terminal plate 621 and one end of the second conductive bar 22 away from the second terminal plate 622 do not exceed the capacitor body 61. This design can shorten the length of the first conductive row and the second conductive row, thereby shortening the current path and reducing transmission loss. It can also make the space utilization rate inside the motor controller higher, which is conducive to the miniaturization design of the motor controller.

[0089] In this embodiment, for example Figure 1 , Fig.32 , Fig.33 and Fig.34As shown, the capacitor 6 and the first conductive component 2 are arranged in the electronic control housing 9, the capacitor body 61 includes a capacitor core 611 and a capacitor housing 612, the capacitor housing 612 is provided with an annular cavity, the capacitor core 611 is arranged in the annular cavity, the capacitor 6 can filter the stray inductance in the motor controller 200 and reduce the overall power consumption of the motor controller 200; the second conductive component 7 is used to transfer the current delivered by the battery pack to the first conductive component 2; the first conductive component 2 can transfer the current to the capacitor 6 so that the capacitor 6 absorbs high pulse current.

[0090] Furthermore, the first conductive bar 21 of the first conductive component 2 has a first wiring portion 212, so that the first conductive bar 21 is electrically connected to the first wiring plate 621 of the capacitor 6 through the first wiring portion 212, and the second conductive bar 22 has a second wiring portion 222, so that the second conductive bar 22 is electrically connected to the second wiring plate 622 of the capacitor 6 through the second wiring portion 222. At the same time, the first conductive bar 21 also has a first busbar wiring portion 211 to be electrically connected to the third conductive bar 71 of the second conductive component 7 of the motor controller 200, and the second conductive bar 22 also has a second busbar wiring portion 221 to be electrically connected to the fourth conductive bar 72 of the second conductive component 7 of the motor controller 200. In this way, the stability of the connection between the components can be guaranteed, thereby ensuring the stability of current transmission.

[0091] Furthermore, for example Figure 20 to Figure 25 As shown, in the projection of the plane parallel to the wiring piece 62, the end of the first conductive bar 21 away from the first wiring piece 621 and the end of the second conductive bar 22 away from the second wiring piece 622 do not exceed the capacitor body 61. At the same time, the second conductive component 7 is arranged on the shell cover 51, and the first conductive component 2 and the second conductive component 7 are connected and matched inside the shell cover 51. In this way, the lengths of the first conductive bar 21 and the second conductive bar 22 are relatively short, which not only reduces the occupation of the first conductive bar 21 and the second conductive bar 22 on the installation space inside the electric control housing 9, but also reduces the overall volume of the motor controller 200. At the same time, under the premise of ensuring the normal cooperation between the first conductive component 2 and the second conductive component 7, the assembly process is optimized and the assembly efficiency is improved. In addition, the first conductive bar 21 and the second conductive bar 22 with shorter lengths are not easy to be deformed and damaged, which can effectively ensure the stability of the connection.

[0092] According to the motor controller 200 in the above embodiment, by setting the second conductive component 7 on the shell cover 51 and the first conductive component 2 under the shell cover 51, the first conductive component 2 and the second conductive component 7 are connected and matched inside the shell cover 51, and in the projection on the plane parallel to the wiring piece 62, the end of the first conductive row 21 away from the first wiring piece 621 and the end of the second conductive row 22 away from the second wiring piece 622 do not exceed the capacitor body 61. Such an assembly design can reduce the length of the first conductive component 2, thereby reducing the occupation of the installation space by the first conductive component 2, making the installation of the first conductive component 2 simpler and more convenient, and improving the assembly efficiency.

[0093] In one embodiment of the present invention, Figures 1 to 34 As shown, the shell cover 51 is arranged at the opening of the electric control housing 9, and the second conductive component 7 is arranged on the shell cover 51. Thus, by installing the second conductive component 7 on the shell cover 51, the internal space occupied by the second conductive component 7 in the motor controller 200 can be reduced, thereby improving the space utilization.

[0094] In a specific embodiment of the present invention, Figures 1 to 34 As shown, the shell cover 51 has a groove 511 with an opening facing away from the electric control housing 9, the second conductive component 7 is installed in the groove 511, and a mounting through hole 5111 is provided on the bottom surface of the groove 511.

Such a design makes full use of the internal space of the shell cover 51, improves space utilization, and is conducive to miniaturized design.

[0096] Furthermore, the first connecting column 231 and the second connecting column 232 are both cylindrical, and the cylindrical first connecting column 231 and the second connecting column 232 are both provided with a first mounting hole 12 with an opening facing the shell cover 51, and the third conductive row 71 and the fourth conductive row 72 of the second conductive component 7 are also both provided with a second mounting hole 12 that cooperates with the first mounting hole 12.

The fastening force provided by the fasteners can also make the electrical connection between the second conductive component 7 and the first conductive component 2 more secure, effectively preventing disconnection.

[0097] In a specific embodiment of the present invention, Figures 1 to 34 As shown, the mounting through hole 5111 includes a first through hole 51111 and a first through hole 51112, the first through hole 51111 is opposite to the first connecting column 231, and the first through hole 51112 is opposite to the second connecting column 232; in this specific embodiment, by utilizing the design of the first through hole 51111 and the first through hole 51112, the first connecting column 231 and the second connecting column 232 can be separated, so that a short circuit between the first connecting column 231 and the second connecting column 232 can be prevented, thereby reducing safety hazards.

[0098] In a specific embodiment of the present invention, Figures 1 to 34As shown, the first conductive bar 21 and the third conductive bar 71 are arranged in parallel, and the second conductive bar 22 and the fourth conductive bar 72 are arranged in parallel. Such an arrangement can reduce the occupation of the axial space of the groove 511 of the shell cover 51 by the first conductive bar 21, the second conductive bar 22, the third conductive bar 71 and the fourth conductive bar 72, and can make full use of the lateral space of the groove 511 to improve space utilization; for example Figure 20 to Figure 25 As shown, the first conductive bar 21, the second conductive bar 22, the third conductive bar 71 and the fourth conductive bar 72 are all designed to be flat, and the groove 511 on the shell cover 51 is also designed to be flat. In this way, the axial installation space occupied by the first conductive bar 21, the second conductive bar 22, the third conductive bar 71, the fourth conductive bar 72 and the groove 511 of the motor controller 200 can be reduced.

[0100] In one embodiment of the present invention, Figures 1 to 34 As shown, the motor controller 200 is characterized in that it also includes a driving board 8, a capacitor 6, a driving board 8 and a first conductive module 100 are sequentially stacked along the axial direction of the motor, for example Figure 1 As shown, in the up and down directions of the motor controller 200, the control board 1 and the isolation board 4 are electrically connected to the drive board 8 and the capacitor 6 through the first conductive component 2. Such a design can effectively reduce the lateral occupation of the capacitor 6, the drive board 8 and the first conductive module 100 in the internal installation space of the motor controller 200, and make full use of the longitudinal space of the internal installation space of the motor controller 200, which can effectively reduce the overall volume of the motor controller 200, thereby reducing the occupation of the installation space inside the vehicle by the motor controller 200 and improving space utilization.

[0101] In this specific embodiment, the inductive sensor 11 is used to monitor the induced current in the magnetic field of the magnetic focusing magnet 24, wherein the inductive sensor 11 is integrated into the control board 1. When the control board 1 is assembled with the first conductive component 2, the inductive sensor 11 on the control board 1 can be directly set in the central area of ​​the magnetic field of the magnetic focusing magnet 24. In this way, there is no need to install the inductive sensor 11 separately, thereby optimizing the overall assembly process of the motor controller 200, saving assembly time and improving assembly efficiency.

[0102] Furthermore, when the magnetic focusing magnet 24 is arranged on the first connecting column 231, the first connecting column 231 can connect the magnetic focusing magnet 24 and the first conductive row 21, so that the magnetic focusing magnet 24 can be electrically connected to the first conductive row 21; when the magnetic focusing magnet 24 is arranged on the second connecting column 232, the second connecting column 232 can connect the magnetic focusing magnet 24 and the second conductive row 22, so that the magnetic focusing magnet 24 can be electrically connected to the second conductive row 22. In this way, when the current on the first conductive row 21 or the second conductive row 22 is transmitted to the magnetic focusing magnet 24, the magnetic focusing magnet 24 can form a magnetic field. At this time, the inductive sensor 11 located in the central area of ​​the magnetic field can effectively monitor the induced current in the magnetic field. In this way, the monitoring structure composed of the magnetic focusing magnet 24 and the inductive sensor 11 is simpler, more practical, and easier to assemble.

[0103] In a specific embodiment of the present invention, Figures 1 to 34 As shown, the magnetic focusing magnet 24 is U-shaped and surrounds the outer circumference of the first connecting column 231 and / or the second connecting column 232, and the inductive sensor 11 is located at the opening of the U-shaped magnetic focusing magnet 24. Fig.26 As shown, the first connecting column 231 and the second connecting column 232 are both cylindrical, and the U-shaped design not only facilitates the matching of the magnetic collecting magnet 24 with the outer peripheral side of the cylindrical first connecting column 231 or the second connecting column 232, but also has a simple and reliable structure, which is convenient for the placement and monitoring of the inductive sensor 11; the inductive sensor 11 located at the opening of the U-shaped magnetic collecting magnet 24 can sense the current in the magnetic field more quickly, and the response speed is faster.

[0104] In some embodiments, the magnetic focusing magnet 24 is a silicon steel sheet, and the inductive sensor 11 is a Hall sensor.

[0105] In a specific embodiment of the present invention, Figures 1 to 34 As shown, the first conductive component 2 also includes a protective shell 3, which is an injection molded part integrally injected on the outer surface of the first conductive row 21, the second conductive row 22 and the magnetic focusing magnet 24. In this specific embodiment, the protective shell 3 can effectively protect the first conductive row 21, the second conductive row 22 and the magnetic focusing magnet 24, prevent external impact or interference from causing damage to the first conductive row 21, the second conductive row 22 and the magnetic focusing magnet 24, and effectively improve the overall safety performance of the first conductive module 100; the protective shell 3 using the integral injection molding process is not only fast in production speed and efficiency, but also low in cost; the protective shell 3 as an injection molded part can not only effectively protect the first conductive row 21, the second conductive row 22 and the magnetic focusing magnet 24, but also can isolate the first conductive row 21, the second conductive row 22 and the magnetic focusing magnet 24 to prevent the three from being electrically connected to each other, thereby playing a role of insulation protection.

[0106] In some embodiments, a protective shell 3 is also injection-molded on the surface of the heating conductive bar 25 .

[0107] In a specific embodiment of the present invention, Figures 1 to 34 As shown, the first conductive bar 21 and the second conductive bar 22 are stacked in the protective shell 3. In this specific embodiment, the stacked first conductive bar 21 and the second conductive bar 22 can effectively reduce the occupation of the first conductive bar 21 and the second conductive bar 22 in the installation space inside the motor controller 200, save installation space, and improve space utilization.

[0108] In a specific embodiment of the present invention, Figures 1 to 34 As shown, the protective shell 3 has a mounting post 31 extending toward the control board 1, and the control board 1 is provided with a mounting hole 12 opposite to the mounting post 31, and the fixing member passes through the mounting hole 12 and is fixedly connected to the mounting post 31. Figure 3 As shown, the protective shell 3 is provided with two mounting posts 31 extending toward the control board 1 , and the two mounting posts 31 can effectively increase the connection strength between the mounting posts 31 and the control board 1 , and at the same time, also increase the overall connection stability of the first conductive module 100 .

[0109] In a specific embodiment of the present invention, Figures 1 to 34 As shown, the protective shell 3 also has a support portion 32 extending toward the control board 1. In the direction from the protective shell 3 to the control board 1, the support portion 32 is used to limit the relative position between the first conductive component 2 and the control board 1. Figure 3 As shown, the support portion 32 is a U-shaped boss protruding toward the control board 1. When the protective shell 3 is connected and assembled with the control board 1, the U-shaped boss with a certain thickness can limit the relative position between the first conductive component 2 and the control board 1, which can not only prevent the first conductive component 2 from interfering with the control board 1, but also prevent the first conductive component 1 from hitting the control board 1 when subjected to external impact, thereby causing damage to the control board 1.

[0110] In a specific embodiment of the present invention, Figures 1 to 34 As shown, the magnetic focusing magnet 24 is located in the support portion 32 , and the support portion 32 can effectively protect the magnetic focusing magnet 24 .

[0111] In a specific embodiment of the present invention, Figures 1 to 34 As shown, the motor controller 200 further includes an isolation plate 4, the side of the control board 1 facing the capacitor 6 is a first side, and the isolation plate 4 is fixed to the first side of the control board 1. In this embodiment, the isolation plate 4 is connected to the control board 1 as a whole, and the isolation plate 4 can separate the control board 1 and the first conductive component 2 to avoid line interference and short circuit between the two, thereby improving the overall safety performance of the motor controller 200.

[0112] In some embodiments, the isolation plate 4 is a plastic part, which can play a role of insulation and isolation.

[0113] In a specific embodiment of the present invention, an adhesive member is provided between the isolation plate 4 and the control plate 1 for fixing the two together, so as to ensure the connection stability between the isolation plate 4 and the control plate 1 and prevent the isolation plate 4 from falling off.

[0114] In a specific embodiment of the present invention, Figures 1 to 34 As shown, the first conductive component 2 is located on the side of the isolation plate 4 away from the control board 1, and a window is provided on the isolation plate 4, and the window is opposite to the magnetic focusing magnet 24. The inductive sensor 11 is installed on the first side surface and is located at a position corresponding to the window on the first side surface, so that when the first conductive component 2 is assembled with the control board 1, the inductive sensor 11 located at the window can be directly arranged in the magnetic field center area of ​​the magnetic focusing magnet 24, which optimizes the assembly process and improves the assembly efficiency.

[0115] In a specific embodiment of the present invention, Figures 1 to 34 As shown, the size of the window is larger than the size of the inductive sensor 11 to allow at least a portion of the inductive sensor 11 to pass through the window. In this way, the inductive sensor 11 can partially pass through the window and extend into the central area of ​​the magnetic field of the magnetic focusing magnet 24 to monitor the induced current and improve the accuracy of monitoring.

[0116] In a specific embodiment of the present invention, Figures 1 to 34 As shown, at least one accommodating groove 41 is provided on the isolation plate 4, and the control board 1 includes a board body 13 and components 15 provided on the board body 13, and the components 15 are fixed in the accommodating groove 41. In this specific embodiment, the provision of the accommodating groove 41 can effectively protect the components 15 on the board body 13 of the control board 1, and prevent the components 15 from being damaged. At the same time, the provision of the accommodating groove 41 also makes full use of the board body 13 space of the isolation plate 4, which not only reduces the occupation of the installation space, but also improves the space utilization rate.

[0117] In a specific embodiment of the present invention, Figures 1 to 34 As shown, the receiving groove 41 opens toward the control board 1 , and the component 15 is bonded to the bottom of the receiving groove 41 by an adhesive, so that the installation stability of the component 15 on the board body 13 of the control board 1 can be ensured and the component 15 can be prevented from falling off.

[0118] In a specific embodiment of the present invention, Figures 1 to 34 As shown, a radial side wall of the shell cover 51 is provided with a connecting hole 5112 , and the connecting hole 5112 corresponds to an end of the second conductive component 7 away from the first conductive component 2 , so as to facilitate the connection of the second conductive component 7 with an external power source.

[0119] For example Figure 20 to Figure 25 As shown, the groove 511 extends toward the outer peripheral side of the shell cover 51, and a connecting hole 5112 is constructed on the outer peripheral wall of the shell cover 51, and the third conductive bar 71 and the fourth conductive bar 72 are suitable for extending out of the connecting hole 5112. In this specific embodiment, the third conductive bar 71 and the fourth conductive bar 72 extending from the connecting hole are used to connect with the battery pack, so that the battery pack can transmit current to the second conductive component 7. Such a design not only integrates the second conductive component 7 into the groove 511 of the shell cover 51, reduces the space occupied by the second conductive component 7, improves the space utilization rate, but also ensures the normal connection between the second conductive component 7 and the battery pack.

[0120] In one embodiment of the present invention, Figures 1 to 34 As shown, the second conductive component 7 further includes a transfer housing 73, which is an injection-molded part integrally injected on the outer surface of the third conductive bar 71 and the fourth conductive bar 72. In this embodiment, the transfer housing 73 using the integral injection molding process is not only fast in production speed and efficiency, but also low in cost; the transfer housing 73 as an injection-molded part can not only effectively protect the third conductive bar 71 and the fourth conductive bar 72, but also can separate the third conductive bar 71 and the fourth conductive bar 72 to prevent electrical connection between the two, thereby playing a role of insulation protection.

[0121] In one embodiment of the present invention, Figures 1 to 34 As shown, the third conductive bar 71 and the fourth conductive bar 72 are stacked in the adapter housing 73. In this embodiment, for example Fig.29 As shown, the third conductive bar 71 and the fourth conductive bar 72 are stacked in the adapter shell 73 along the axial direction of the center hole. The stacked third conductive bar 71 and the fourth conductive bar 72 can effectively reduce the installation space occupied by the third conductive bar 71 and the fourth conductive bar 72 inside the shell cover 51, saving installation space and improving space utilization.

[0122] In a specific embodiment of the present invention, Figures 1 to 34 As shown, the second conductive component 7 also includes a magnetic ring 74 which is sheathed on the adapter housing 73; in this specific embodiment, the magnetic ring 74 can enhance the inductance of the magnetic ring 74 and enhance the overall electromagnetic compatibility of the motor controller 200. Figure 20 to Figure 25 As shown, the second conductive component 7 and the first conductive component 2 are designed to be stacked up and down, so that the installation point of the magnetic ring 74 is close to the connection end between the second conductive component 7 and the first conductive component 2. In this way, the magnetic circuit can be effectively shortened, the performance of the magnetic ring 74 can be improved, and the electromagnetic compatibility of the motor controller 200 can be further enhanced.

[0123] Furthermore, the magnetic ring 74 is sleeved on the overlapping portion of the third conductive row 71 and the fourth conductive row 72 of the second conductive component 7 , so that the volume of the magnetic ring 74 can be reduced and the performance of the magnetic ring 74 can be further improved.

[0124] In a specific embodiment of the present invention, Figures 1 to 34 As shown, the magnetic ring 74 includes a first magnetic ring 741 and a second magnetic ring 742 , and the first magnetic ring 741 and the second magnetic ring 742 are connected end to end to form a ring-shaped magnetic ring 74 . This design facilitates the installation and coordination of the magnetic ring 74 and can effectively improve the assembly efficiency of the magnetic ring 74 .

For example, Fig.21 As shown, two filter capacitors 751 are provided, and both filter capacitors 751 are installed on the side of the circuit board 752 facing the shell cover 51. The first filter conductive row 753 and the second filter conductive row 754 are provided on the circuit board 752 in the direction toward the second conductive component 7, and the first filter conductive row 753 and the second filter conductive row 754 respectively lead out the first connection terminal 7531 and the second connection terminal 7541 so as to be connected to the third conductive row 71 and the fourth conductive row 72 of the second conductive component 7. Such a design makes full use of the installation space in the groove 511 and improves the anti-interference ability of the motor controller 200.

[0128] In some embodiments, the capacitor body 61 includes a capacitor housing 612, one side of the capacitor housing 612 is covered by a glue-filled surface, and the first conductive component 2 is supported on the glue-filled surface. In this way, the glue-filled surface can not only play an insulating role, but also support the first conductive component 2.

[0132] Furthermore, the first connection portion 213 and the second connection portion 223 are both connection holes, wherein the three connection holes on the first conductive row 21 are arranged in a triangle, and the three connection holes on the second conductive row 22 are also arranged in a triangle, so that the connection stability between the first conductive row 21 and the first terminal plate 621, and between the second conductive row 22 and the second terminal plate 622 can be improved; in addition, the three first connection portions 213 arranged in a triangle and the three second connection portions 223 arranged in a triangle are arranged alternately up and down, so that interference between the first connection portions 213 and the second connection portions 223 can be prevented, thereby affecting assembly.

[0133] Furthermore, the third connection part 251 is also a connection hole, and is located in the middle position of the three first connection parts 213 and the three second connection parts 223. At the same time, avoidance holes are opened in the middle position of the three first connection parts 213 and the middle position of the three second connection parts 223 to allow the fixing parts to pass through and connect the heating conductive bar 25 with the motor. Such a design not only facilitates the assembly of the heating conductive bar 25, but also can reduce the space occupied by the heating conductive bar 25.
