[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0045] Amidst dwindling energy resources and increasing pollution, pure electric vehicles are gaining popularity. With the rapid development of the electric vehicle industry, vehicle interiors are becoming increasingly compact, placing increasing demands on motor controller size. Traditionally, two-wheel-drive electric vehicles utilize two separate motor controllers to independently drive each motor. This significantly necessitates greater internal space within the vehicle to accommodate the two motor controllers. This significantly compromises overall vehicle layout, and existing motor controllers often have a chaotic layout of internal components, resulting in a complex internal structure and increased space requirements.

[0046] In view of this, the present application proposes a motor controller, Figures 1 to 7 This is a structural diagram of an embodiment of the motor controller provided in the present application. The motor controller provided in the present application has a reasonable structural layout, high integration, and small space occupation. The motor controller will be described in detail below in conjunction with the main drawings.

[0047] See also Figure 1 This embodiment provides a motor controller 100, which includes a plurality of connectors and a box 1. The box 1 has two mounting surfaces 11 arranged opposite to each other along a first direction, and a plurality of connectors are installed on each mounting surface 11.

[0048] In the technical solution of the present application, multiple connectors are located on two opposite mounting surfaces 11 of the box body 1, with a high degree of integration and reasonable space utilization, which improves the compactness of the structure, reduces the space occupied by the motor controller 100, and avoids the situation where multiple connectors are distributed in multiple directions, causing the motor controller 100 to occupy a large external space; at the same time, at least part of the connectors are located on the two opposite mounting surfaces 11 of the box body 1, and the connectors that need to be externally connected are concentrated on the two mounting surfaces 11, which is convenient for the operator to operate and does not require the box body 1 to be rotated multiple times, thereby improving work efficiency.

[0049] For ease of description, Figure 1 Taking the first direction as an example, the second direction intersects with the first direction, the third direction intersects with the second direction, and the third direction intersects with the first direction, wherein the first direction is the length direction of the box 1, the second direction is the width direction of the box 1, and the third direction is the height direction of the box 1.

[0050] The motor controller 100 provided in this application is a dual-motor controller. One motor controller 100 can control the operation of two motors at the same time. Compared with two single-motor controllers controlling the operation of two motors respectively, the motor controller 100 provided in this application has high integration, fewer parts, and saves space.

[0051] In some embodiments, multiple through holes are provided on the two mounting surfaces 11 of the box body 1, and the multiple through holes are used for multiple connectors to pass through. Such a configuration enables the components in the box body 1 to be directly connected to the connectors without the need for adapter cables, thereby improving the compactness of the structure and reducing the volume of the motor controller 100.

[0052] See also Figure 1 In this embodiment, the motor controller 100 includes multiple connector assemblies installed in the housing 1. Each connector assembly extends along a first direction and is connected to a corresponding connector. By properly arranging the multiple connector assemblies, the multiple connector assemblies can be connected to the corresponding connectors, improving the compactness of the structure and thereby increasing the integration of the motor controller 100. This optimizes the space required for the motor controller 100 and facilitates its lightweight design. This also simplifies the assembly process and improves production and assembly efficiency.

[0053] In some embodiments, please refer to Figure 1 Multiple connectors are mounted on two mounting surfaces that are opposite each other along a first direction. Therefore, the multiple connectors on each mounting surface are spaced apart along a second direction. The multiple connector assemblies are arranged along the second direction, allowing the multiple connector assemblies to correspond to the multiple connectors. During connection, the multiple connector assemblies can directly connect to the multiple connectors, eliminating the need for intermediate adapter structures. This improves the integration of the motor controller 100, optimizes the space requirements of the motor controller 100, and facilitates lightweighting of the motor controller 100. This also simplifies the assembly process and improves production and assembly efficiency.

[0054] See also Figure 1 and Figure 2 In this embodiment, the motor controller 100 includes a driver circuit board 4. In the third orientation, the driver circuit board 4 is positioned above the multiple connector assemblies. This arrangement allows the multiple connector assemblies to be directly connected to the driver circuit board 4, eliminating the need for intermediate wiring harnesses and improving the compactness of the structure. The driver circuit board 4 serves as the control center, electrically connecting the multiple connector assemblies for controlling them. It also drives the rotation of the motor connected to the motor controller 100.

[0055] In some embodiments, as Figure 1As shown, one side of the box body 1 is open, and the motor controller 100 further includes an isolation plate 9. A high-voltage area cavity is defined between the isolation plate 9 and the bottom wall of the box body 1. The driving circuit board 4 and multiple connector assemblies are located in the high-voltage area cavity. The voltage in the driving circuit board 4 and multiple connector assemblies is relatively high. Placing the driving circuit board 4 and multiple connector assemblies in the high-voltage area cavity can avoid high voltage electricity from damaging the low-voltage structure, thereby improving safety.

[0056] Furthermore, if Figure 1 As shown, the isolation plate 9 extends along the first direction, and the two ends of the isolation plate 9 along the first direction are respectively connected to the two mounting surfaces 11 of the box body 1. A high-pressure area cavity is formed between the side of the isolation plate 9 facing the bottom wall of the box body 1 and the box body 1, and a low-pressure area cavity is formed on the side of the isolation plate 9 facing away from the bottom wall of the box body 1. The low-pressure area cavity can be used to install low-voltage electrical appliances.

[0057] In some embodiments, the motor controller 100 also includes a control component 8, which is located in the low-voltage area cavity. The function of the isolation plate 9 is to separate the control component 8 from the drive circuit board 4, thereby preventing the high-voltage part from affecting the control component 8, so that the control component 8 can work normally.

[0058] In some embodiments, please refer to Figure 1 and Figure 2 The plurality of connector assemblies includes a first electronic assembly 3, which is used to filter out interference signals in the current to ensure the normal operation of the motor. The first electronic assembly 3 and the driver circuit board 4 are disposed within the housing 1 and are electrically connected to each other. The first electronic assembly 3 is directly connected to the driver circuit board 4, allowing the first electronic assembly 3 to be integrated on the driver circuit board 4, thereby reducing the adapter structure between the first electronic assembly 3 and the driver circuit board 4 and making the internal structure of the motor controller 100 more compact.

[0059] In some embodiments, please refer to Figure 1 The plurality of connectors include two first connectors 21, which are respectively mounted on the two mounting surfaces 11 and arranged opposite to each other. The first electronic component 3 is electrically connected to the two first connectors 21. It should be noted that the first electronic component 3 can be directly connected to the two first connectors 21 or connected to the two first connectors 21 via an adapter cable. In this embodiment, the first electronic component 3 is disposed between the two first connectors 21 and is directly electrically connected to the two first connectors 21. In this way, the intermediate adapter structure is eliminated, the structure of the motor controller 100 is more compact, and the space utilization rate is improved.

[0060] See also Figure 1 and Figure 4The first electronic component 3 includes two first filters 31, which are located between the two first connectors 21. The two first filters 31 are arranged opposite to each other, and the ends of the two first filters 31 facing away from each other are electrically connected to the two first connectors 21 respectively. The first filters 31 can filter out interference signals in the current, thereby ensuring the normal operation of the two motors connected to the motor controller 100.

[0061] More specifically, the two first filters 31 are electrically connected to the driving circuit board 4 respectively.

[0062] In some embodiments, the axes of the two first connectors 21 are arranged to overlap, and the axes of the two first filters 31 connected to the two first connectors 21 also overlap. This arrangement is intended to improve the space utilization of the housing 1 in the first direction. If the axes of the two first connectors 21 are not overlapped, that is, the two first connectors 21 are staggered, the two first filters 31 will also be staggered, and the space occupied by the two first filters 31 in the first direction will increase, resulting in an increase in the overall volume of the motor controller 100. The axes of the two first connectors 21 overlap, and the axes of the two first filters 31 also overlap, which rationally utilizes the space of the housing 1 in the first direction, improves the compactness of the structure, and thus improves the integration of the motor controller 100, thereby optimizing the space of the motor controller 100 and facilitating the lightweighting of the motor controller 100. At the same time, it also simplifies the assembly process and improves the efficiency of production and assembly.

[0063] See also Figure 1 and Figure 2 In this embodiment, the driver circuit board 4 is disposed above the first electronic assembly 3. This arrangement allows the two first filters 31 to be directly connected to the driver circuit board 4, thereby enabling the two first filters 31 to be integrated on the driver circuit board 4. This reduces the number of adapters between the first filters 31 and the driver circuit board 4, making the internal structure of the motor controller 100 more compact, thereby improving the integration of the motor controller 100, optimizing the space required for the motor controller 100, and facilitating its lightweighting. Furthermore, the reduction in adapters between the first filters and the driver 100 simplifies the assembly process and improves production and assembly efficiency.

[0064] It should be noted that the connection method between the two first filters 31 and the driver circuit board 4 is not limited. Figure 2 The first electronic component 3 further includes two adapter bank groups 32 , each adapter bank corresponding to one first filter 31 .

[0065] Specifically, see Figure 4 and Figure 7Each adapter row is provided on the side of the first filter 31 facing the driver circuit board 4. More specifically, a plurality of first vias 41 are formed on the driver circuit board 4. Each adapter row group 32 includes a plurality of adapter rows 320 spaced apart along the second direction. Each adapter row 320 includes a first pin 321 and a first connecting piece 322. Each first pin corresponds to a first via 41. The first via 41 and the first pin 321 are electrically connected to each other, thereby electrically connecting the first filter 31 to the driver circuit board 4. The first connecting piece 322 includes a first portion 3221 and a second portion 3222. The first portion 3221 extends along the second direction, and the second portion 3222 extends along the first direction. The first portion 3221 is connected to the driver circuit board 4 via the first pin 321, and the second portion 3222 is connected to the first filter 31. The first portion 3221 is used to adjust the position of the first pin 321 in the first direction so that each first pin 321 can mate with each via 41. The second portion 3222 is used to electrically connect the first pin 321 to the first filter 31. The first connecting piece 322 is used to bridge the gap between the first pin 321 and the first filter 31 in the first and second directions, allowing the first filter 31 to be electrically connected to the first connector 21 and also electrically connected to the driver circuit board 4 via the first pin 321. Thus, through the electrical connection between the first pin 321 and the first via 41, a direct connection between the first filter 31 and the driver circuit board 4 is achieved, allowing the first filter 31 to be integrated on the driver circuit board 4, thereby reducing the need for an adapter between the first filter 31 and the driver circuit board 4. This also secures the first filter 31 to the driver circuit board 4, improving structural stability and making the internal structure of the motor controller 100 more compact. This improves the integration of the motor controller 100, optimizes the space required for the motor controller 100, and contributes to the lightweight design of the motor controller 100.

[0066] In this embodiment, the spatial position of the first filter 31 is reasonably utilized, one end of the first filter 31 along the first direction is connected to the first connector 21, and the end of the first filter 31 facing the driving circuit board 4 is electrically connected to the driving circuit board 4. The structure between the components is highly compact and the motor controller 100 has a high degree of integration.

[0067] See also Figure 2 and Figure 3 The motor controller 100 further includes a second electronic component 6, which is installed in the housing 1 and is located on one side of the first electronic component 3 along the second direction. The second electronic component 6 has the same function as the first electronic component 3, and both can perform filtering, thereby improving the filtering efficiency of the motor controller 100.

[0068] More specifically, the second electronic component 6 is electrically connected to the driver circuit board 4. It should be noted that the second electronic component 6 and the driver circuit board 4 can be electrically connected directly or through other structures, depending on the actual situation.

[0069] Please continue reading Figure 3 The plurality of connectors further includes a second connector 22, which is mounted on any one of the mounting surfaces 11. The second connector 22 is located on one side of the two first connectors 21 along the second direction, and the second connector 22 is electrically connected to the second electronic component 6. This arrangement ensures that the second connector 22 and the first connector 21 do not interfere with each other.

[0070] See also Figure 2 and Figure 3 The second electronic component 6 includes a second filter 61 and a capacitor 62. Taking into account the problem of idle utilization, the second filter 61 and the capacitor 62 are arranged along the first direction. The second filter 61 is electrically connected to the second connector 22 and the capacitor 62, and the capacitor 62 is electrically connected to the second filter 61 and the driver circuit board 4. It should be noted that the capacitor 62 can smooth the power input and reduce voltage noise, and play a buffering and filtering role during motor startup, acceleration and deceleration or variable frequency speed regulation. The capacitor 62 can stabilize the operating voltage of the motor controller 100, reduce the impact of voltage fluctuations on the motor, improve the stability and reliability of the motor operation, and also reduce the current impact when the motor starts, thereby extending the life of the motor.

[0071] In some embodiments, see Figure 3 The motor controller 100 also includes a drive component 5, which is arranged in the box 1 and between the first electronic component 3 and the second electronic component 6. The drive component 5 includes two IGBTs 52 (Insulate Gate Bipolar Transistor). The two IGBTs 52 are arranged side by side along the first direction. The two IGBTs 52 are directly connected to the drive circuit board 4, so that the two IGBTs 52 can be integrated on the drive circuit board 4, making the internal structure of the motor controller 100 more compact, thereby improving the integration of the motor controller 100, thereby optimizing the space of the motor controller 100, and facilitating the lightweighting of the motor controller 100.

[0072] In some embodiments, each IGBT 52 is provided with a connection row 51, and the connection row 51 includes a plurality of second pins. A plurality of second through holes are formed on the driving circuit board 4, and each second pin corresponds to a second via 42. The second pin and the second via 42 are electrically connected to each other, thereby realizing a direct connection between the IGBT 52 and the driving circuit board 4, so that the IGBT 52 can be integrated on the driving circuit board 4, thereby reducing the adapter structure between the IGBT 52 and the driving circuit board 4, and at the same time, the IGBT 52 and the driving circuit board 4 are fixed to each other, thereby improving the stability of the structure, making the internal structure of the motor controller 100 more compact, thereby improving the integration of the motor controller 100, thereby optimizing the space of the motor controller 100, and facilitating the lightweighting of the motor controller 100.

[0073] Furthermore, the drive assembly 5 electrically connects the capacitor 62 to the drive circuit board 4. In this embodiment, one end of the capacitor 62 in the first direction is connected to the second filter 61, and one end of the capacitor 62 in the second direction is connected to one of the IGBTs 52. By properly utilizing the positional relationship between the capacitor 62, the second filter 61, and the IGBT 52, the internal structure of the motor controller 100 is made more compact, thereby improving the integration of the motor controller 100.

[0074] Furthermore, to facilitate the connection between the drive assembly 5, the drive circuit board 4, and the second electronic assembly 6, in this embodiment, in the third direction, the drive assembly 5 and the second electronic assembly 6 are located below the drive circuit board 4. This makes the internal structure of the motor controller 100 more compact, thereby improving the integration of the motor controller 100, thereby optimizing the space of the motor controller 100 and facilitating the lightweighting of the motor controller 100.

[0075] In this embodiment, the driving circuit board 4 includes a DC circuit area, a driving circuit area and an AC circuit area. The driving area is between the DC circuit area and the AC circuit area. The DC circuit area is electrically connected to the second electronic component 6, the driving circuit area is electrically connected to the driving component 5, and the AC circuit area is electrically connected to the first electronic component 3. The first electronic component 3, the second electronic component 6 and the driving component 5 are arranged according to the area of the driving circuit board 4, and the space is reasonably utilized, so that the internal structure of the motor controller 100 is more compact, thereby improving the integration of the motor controller 100.

[0076] See also Figure 1 and Figure 6The motor controller 100 further includes a heat dissipation component 7, which is located in the housing 1. The heat dissipation component 7 is used to dissipate heat for at least one of the drive component 5, the first electronic component 3, and the second electronic component 6. It should be noted that the heat dissipation component 7 can dissipate heat for only one of the components, or it can dissipate heat for all three components at the same time. Specifically, in one embodiment, the heat dissipation component 7 is thermally conductively connected to the drive component 5 to dissipate heat for the drive component 5. In another embodiment, the heat dissipation component 7 is thermally conductively connected to the drive component 5, the first electronic component 3, and the second electronic component 6, and dissipates heat for the first electronic component 3, the second electronic component 6, and the drive component 5 at the same time.

[0077] It is understandable that when the driving component 5, the first electronic component 3 and the second electronic component 6 are working, heat will be generated. In order to prevent the driving component 5, the first electronic component 3 and the second electronic component 6 from overheating and causing thermal runaway, a heat dissipation component 7 needs to be set to dissipate heat for the driving component 5, the first electronic component 3 and the second electronic component 6, thereby improving safety.

[0078] In some embodiments, in the third direction, the heat dissipation component 7 is located below the drive component 5. Specifically, the drive component 5 includes two IGBTs 52. The two IGBTs 52 are relatively small in size and occupy less space. The heat dissipation component 7 is arranged below the two IGBTs 52, and the space below the two IGBTs 52 is reasonably utilized, so that the internal structure of the motor controller 100 is more compact, thereby improving the integration of the motor controller 100, thereby optimizing the space of the motor controller 100, and facilitating the lightweighting of the motor controller 100.

[0079] In some embodiments, see Figure 2 and Figure 5 The top of the heat dissipation component 7 is in contact with the driving component 5 to absorb the heat generated by the driving component 5. The heat dissipation component 7 has two side surfaces arranged opposite to each other along the second direction. The two side surfaces are in contact with the first electronic component 3 and the second electronic component 6 respectively to absorb the heat generated by the first electronic component 3 and the second electronic component 6 to prevent the temperature of the motor controller 100 from being too high.

[0080] For further information, please refer to Figure 2 and Figure 5The plurality of connectors further includes two third connectors 23. The heat dissipation assembly 7 includes a heat pipe disposed between the two third connectors 23. The two third connectors 23 are mounted on the two mounting surfaces 11 and are disposed opposite each other. Specifically, the drive assembly 5, the first electronic assembly 3, and the second electronic assembly 6 are respectively attached to the heat pipes, thereby further improving the heat transfer efficiency between the heat dissipation assembly 7 and the drive assembly 5, the first electronic assembly 3, and the second electronic assembly 6. This improves the heat dissipation efficiency of the heat dissipation assembly 7 to the drive assembly 5, the first electronic assembly 3, and the second electronic assembly 6, thereby further improving the safety of the motor controller 100.

[0081] In some embodiments, see Figure 6 The heat dissipation component 7 is provided with a plurality of heat dissipation fins 71 on the side away from the drive component 5. The heat dissipation fins 71 are provided corresponding to the drive component 5, further improving the heat dissipation efficiency of the heat dissipation component 7 to the drive component, thereby further improving safety.

[0082] In some embodiments, the axes of the two third connectors 23 are arranged to coincide. This arrangement minimizes the heat pipe's path and places it substantially parallel to the first direction, improving the space utilization of the housing 1 in the first direction and the compactness of the structure, thereby increasing the integration of the motor controller 100 and optimizing the space within the motor controller 100, thereby facilitating its lightweight design. Furthermore, this arrangement simplifies the assembly process and enhances production efficiency.

[0083] In some embodiments, the common axis of the two first connectors 21 is the first axis, the axis of the second connector 22 is the second axis, and the common axis of the two third connectors 23 is the third axis. The first axis, the second axis, and the third axis are all parallel to each other. This arrangement eliminates interference between the first electronic component 3, the second electronic component 6, the driver component 5, the driver circuit board 4, and the heat dissipation component 7, thereby improving space utilization.

[0084] More specifically, see Figure 2, the driving circuit board 4 provided in the present application completely covers the top of the driving component 5 and the first electronic component 3. Since the capacitor 62 in the second electronic component 6 is connected to the driving circuit board 4 through the driving component 5, the second electronic component 6 is not directly connected to the driving circuit board 4, so the driving circuit board 4 does not need to cover the second electronic component 6. Furthermore, when the layout of the components on the driving circuit board 4 is reasonable, the driving circuit board 4 may not cover the second electronic component 6 at all. At the same time, considering that the driving circuit board 4 is a high-voltage component and the control component 8 is a low-voltage component, in order to avoid the high-voltage component from affecting the low-voltage component, the control component 8 needs to avoid the driving circuit board 4 as much as possible. In this embodiment, the control component 8 is arranged above the second electronic component 6, corresponding to the control component 8 and the second electronic component 6. Such a setting can reduce the impact of high-voltage components on low-voltage components, thereby improving the safety of the motor controller 100.

[0085] In some embodiments, please refer to Figure 1 A sealed cavity is formed between the first electronic assembly 3, the second electronic assembly 6, the driver circuit board 4, and the bottom of the housing 1. The driver assembly 5 is disposed within the sealed cavity. The driver assembly 5 includes two IGBTs 52. The sealed cavity isolates the IGBTs 52, thereby preventing arcing, explosive shock, and other damage to other components caused by the two IGBTs 52.

[0086] Furthermore, in some embodiments, the motor controller 100 further includes a sealant, which is disposed in the sealed cavity and wraps around the drive assembly 5. The sealant can effectively prevent arcing and explosion shock between the high-voltage terminals of the IGBT 52, thereby improving the safety of the motor controller 100.

[0087] See also Figure 1 and Figure 6 The control assembly 8 includes a fourth connector 24 and a control circuit board. The control assembly 8 is connected to the fourth connector, which is used to connect an external wiring harness to the control circuit board. More specifically, the fourth connector 24 corresponds to the second connector 22. More specifically, in a preferred embodiment, the orthographic projection of the axis of the fourth connector 24 on a horizontal plane coincides with the orthographic projection of the axis of the second connector 22 on a horizontal plane. This arrangement allows the fourth connector 24 to correspond to the second connector 22, improving space utilization and increasing the integration of the motor controller 100. This optimizes the space of the motor controller 100 and facilitates its lightweight design.

[0088] In some embodiments, the motor controller 100 further includes a cover plate, which is formed with a receiving cavity, and the control component 8 is disposed in the receiving cavity, so that the cover plate can be connected to the box body 1.
