Description

Technical Field

[0001] This application belongs to the field of controller technology, and more specifically, relates to an electronic controller, an electric drive assembly, and a vehicle. Background Technology

[0002] The PCBA (Printed Circuit Board Assembly) is the core hardware carrier of an electronic controller. Its layout and design directly determine the controller's EMC (Electromagnetic Compatibility) performance, which is a key indicator for the stable operation and compatibility of the electronic controller with other devices. As the demand for miniaturization and high-frequency operation in intelligent control systems continues to increase, traditional EMC solutions are gradually revealing significant shortcomings: on the one hand, shielding effectiveness is insufficient to meet the electromagnetic interference suppression requirements in high-frequency scenarios; on the other hand, they are prone to compatibility conflicts with system integration requirements. Crucially, increased integration leads to a significant reduction in the internal space of the electronic controller, and the combination of conventional electromagnetic shielding covers and discrete filtering components frequently results in structural interference, severely restricting the miniaturization design and performance stability of the controller.

[0003] Currently, the internal structural layout of electronic controller PCBAs on the market mainly falls into two categories: one is the integration of filtering components with the motherboard, and the other is the separation of filtering components and the motherboard. However, both layouts suffer from insufficient compatibility between the motherboard design and EMC shielding requirements, resulting in significant limitations on the electromagnetic compatibility (EMC) performance of the electronic controller.

[0004] While integrating filtering components onto the motherboard offers the advantage of simplified assembly, it also presents several drawbacks: the filtering components directly occupy motherboard space, forcing an increase in motherboard size and consequently resulting in a larger overall controller volume; the significant height differences among different electronic components lead to low space utilization in the vertical direction; the integrated structure of the motherboard makes it difficult to add additional shielding structures such as shielding covers or independent sealed cavities; and for critical components with high shielding requirements, such as input and output terminals, effective protection solutions cannot be developed, resulting in poor electromagnetic interference suppression.

[0005] While the layout scheme of separating the filter components from the motherboard and adding a shielding plate between the filter and the motherboard can achieve physical separation between the filter components and the motherboard to a certain extent and slightly improve the space utilization, the filter structure itself is an integral structure, which still occupies a large horizontal space and cannot fundamentally solve the core problem of low internal space utilization of the equipment. Utility Model Content

[0006] The purpose of this application is to provide an electronic controller, an electric drive assembly, and a vehicle, which aims to solve the problem of low space utilization in existing electronic controllers.

[0007] In a first aspect, embodiments of this application provide an electronic controller, including: The outer casing includes a housing and a partition plate disposed within the housing, the partition plate dividing the housing into multiple independent accommodating cavities from top to bottom; The filtering unit includes multiple filtering modules, which are disposed within the accommodating cavity, and the multiple filtering modules are arranged in a one-to-one correspondence with the multiple accommodating cavities, with adjacent sets of filtering modules being electrically connected. A driving unit includes a driving board, input terminals, and output terminals. The driving board and the top-mounted filter module are located within the same accommodating cavity and are spaced apart from the top-mounted filter module along a vertical direction. The input terminals are used to electrically connect the driving board and the filter module within the same accommodating cavity. The output terminals are electrically connected to the bottom-mounted filter module. A shielding plate is disposed between the drive board and the filter module and fixed to the housing. The shielding plate is used to shield the interference signals of the drive board and the filter module within the same accommodating cavity. The beneficial effects of the electronic controller provided in this application are as follows: Compared with the prior art, by dividing the housing into multiple independent cavities distributed vertically through a partition plate, and with multiple filter modules arranged in a one-to-one correspondence with the cavities, the vertical utilization of the internal space of the housing is achieved. This changes the space-occupying pattern of the integral layout of the filter unit in the existing solution, effectively solving the problem of the existing integral filter unit occupying too much horizontal space, improving the utilization rate of the internal space of the electronic controller, and effectively adapting to the development needs of miniaturization. The driver board and the top filter module are distributed vertically and horizontally in the same cavity. Combined with the electrical connection of the input and output terminals, the signal transmission path is shortened while optimizing the spatial layout, reducing signal attenuation and delay. The shielding plate placed between the driver board and the filter module can effectively suppress the mutual electromagnetic interference between the two in the same cavity, further enhancing the overall EMC performance and solving the problem of insufficient shielding structure adaptation in the traditional layout. This application adopts a distributed design for the filter modules, which can flexibly configure filter modules of different specifications or parameters according to the filtering requirements and signal characteristics of different circuit parts, enhancing the design flexibility.

[0008] In conjunction with the first aspect, in one possible implementation, the housing further includes a separation frame disposed within the housing, the separation frame and the housing enclosing a shielding cavity, and the output terminal and / or the input terminal being disposed within the shielding cavity.

[0009] In the above technical solution, by setting a separation frame inside the housing, the separation frame and the housing enclose an independent shielding cavity, and the input terminals and / or output terminals are placed in the shielding cavity, the problem of the input terminals, output terminals and filter units being distributed in the same cavity in the traditional layout is solved. This effectively blocks the electromagnetic interference radiation and coupling path of the input terminals and output terminals, and further improves the overall EMC performance of the electronic controller.

[0010] In conjunction with the first aspect, in one possible implementation, the electronic controller further includes terminals for electrically connecting two adjacent sets of filter modules, and a shielding tube sleeved outside the terminals. The partition plate has clearance holes, and the shielding tube is inserted into the clearance holes and is interference-fitted with the clearance holes.

[0011] In the above technical solution, the shielding tube and the clearance hole are interference-fitted, thereby blocking electromagnetic interference leakage and coupling of the terminal block, avoiding electromagnetic crosstalk between adjacent cavities due to signal transmission, and improving the EMC performance of the electronic controller. In addition, the combination structure of the terminal block and the shielding tube does not require complex wiring, is suitable for layered layout space design, and does not occupy too much internal space while ensuring efficient conductive connection between adjacent filter modules, thus balancing connection reliability, shielding effectiveness and space utilization.

[0012] In conjunction with the first aspect, in one possible implementation, the housing includes an upper receiving area and a lower receiving area distributed from top to bottom, the cross-section of the upper receiving area being adapted to the contour of the drive plate, and the cross-section of the lower receiving area being adapted to the contour of the filter module.

[0013] In the above technical solution, the drive board and filter module are installed in close fit with the upper and lower accommodating areas, respectively, which minimizes the redundant gaps between the components and the inner wall of the housing, avoids wasting space, and makes the internal structure layout more compact. The upper and lower accommodating areas realize the vertical stacking layout of the drive board and filter module, which significantly shortens the horizontal occupancy of the equipment compared with the traditional horizontally dispersed arrangement, and realizes the efficient use of electronic controller space.

[0014] In conjunction with the first aspect, in one possible implementation, the plurality of filter modules are flush with one end of the drive board in the vertical direction, and the other end forms a staggered distribution structure, with the housing conforming to the shape of the filter modules and the drive board.

[0015] In the above technical solution, the housing is designed to conform to the shape of the filter module and drive board, avoiding excessive lateral space occupation by the housing at staggered ends due to the need to accommodate the largest-sized components. This allows for more assembly space to be reserved for peripheral components of the electronic controller, improving the flexibility of adaptation to the electric drive assembly and vehicle installation environment. The flush end makes the outer surface of the housing a flat plane, reducing redundant space occupation and ensuring the structural compactness of the core mounting side of the electronic controller.

[0016] In conjunction with the first aspect, in one possible implementation, the cross-sectional dimensions of the plurality of filter modules gradually decrease from top to bottom, and the cross-sectional dimension of the drive board is larger than the cross-sectional dimension of the filter modules, so that the lower part of the housing forms a clearance zone.

[0017] In the above technical solution, the filter module's gradient cross-section design from top to bottom, combined with the large-size layout of the drive board, allows the internal components to form a compact structure that is "wider at the top and narrower at the bottom." The vertical space is maximized through the size gradient distribution, while the clearance area at the bottom of the housing cleverly releases additional space, providing sufficient clearance for the wiring harness layout, mounting brackets, or other components around the electronic controller, greatly improving the space adaptability with the electric drive assembly and vehicle installation environment.

[0018] In conjunction with the first aspect, in one possible implementation, the housing further includes a baffle disposed within the accommodating cavity, the baffle dividing the accommodating cavity laterally into multiple mounting chambers, the filtering module including multiple sequentially electrically connected filtering modules, each mounting chamber being provided with a set of filtering modules, and the filtering module at the first end being electrically connected to the filtering module above, and the filtering module at the last end being electrically connected to the filtering module below.

[0019] In the above technical solution, the baffle horizontally divides the accommodating cavity into multiple independent installation chambers, thereby separating and setting up multiple filter modules. This avoids the space congestion and interference caused by the centralized arrangement of multiple filter modules, and the division into independent installation chambers ensures the orderly arrangement of each filter module. The design of one installation chamber for each filter module allows for precise matching of installation space according to the functional requirements and size specifications of the filter modules, avoiding redundant space waste. At the same time, the horizontally separated structure does not affect the vertical connection of the upper and lower filter modules. The precise electrical connection between the first and last filter modules ensures the regularity and continuity of the signal transmission path, achieving synergy between horizontal space optimization and vertical functional connection.

[0020] In conjunction with the first aspect, in one possible implementation, the top and / or bottom of the housing are provided with assembly openings, and the housing further includes a shielding cover disposed on the assembly openings.

[0021] In the above technical solution, the top and / or bottom mounting openings provide ample operating space for the installation of core components such as internal filter modules and drive boards, avoiding the spatial limitations imposed by traditional enclosed housings on component assembly, reducing the assembly difficulty of multi-layered layout components, and facilitating precise positioning of each module and connector. The detachable design of the shielding cover allows direct access to the target component simply by opening the corresponding opening, improving maintenance efficiency and reducing the impact on surrounding assembly structures.

[0022] Secondly, embodiments of this application also provide an electric drive assembly, including the aforementioned electronic controller.

[0023] The beneficial effects of the electric drive assembly provided in this application are as follows: Compared with the prior art, it adopts the aforementioned electronic controller, dividing the housing into multiple independent cavities distributed vertically by a partition plate. Combined with a layout where multiple filter modules are correspondingly arranged in one-to-one correspondence with the cavities, it achieves vertical utilization of the internal space of the housing. This changes the space-occupying pattern of the integral layout of the filter unit in existing solutions, effectively solving the problem of excessive horizontal space occupation by existing integral filter units, improving the utilization rate of the internal space of the electronic controller, and effectively adapting to the development needs of miniaturization. The drive board and the top filter module are distributed vertically and horizontally within the same cavity. Combined with the electrical connection of the input and output terminals, the signal transmission path is shortened while optimizing the spatial layout, reducing signal attenuation and delay. A shielding plate is placed between the drive board and the filter module, which can effectively suppress mutual electromagnetic interference between the two within the same cavity, further enhancing the overall EMC performance and solving the problem of insufficient shielding structure adaptation in traditional layouts. This application adopts a distributed design for the filter modules, allowing for flexible configuration of filter modules of different specifications or parameters according to the filtering requirements and signal characteristics of different circuit sections, enhancing design flexibility.

[0024] Thirdly, embodiments of this application also provide a vehicle including the aforementioned electric drive assembly.

[0025] The beneficial effects of the vehicle provided in this application are as follows: Compared with the prior art, it adopts the aforementioned electric drive assembly, which divides the housing into multiple independent cavities distributed vertically by a partition plate. This, combined with a layout where multiple filter modules are correspondingly arranged in one-to-one correspondence with the cavities, achieves vertical utilization of the internal space of the housing. This changes the space-occupying pattern of the integral filter unit layout in existing solutions, effectively solving the problem of excessive lateral space occupation by existing integral filter units, improving the utilization rate of the internal space of the electronic controller, and effectively adapting to the development needs of miniaturization. The drive board and the top filter module are distributed vertically and horizontally within the same cavity. Combined with the electrical connection of the input and output terminals, the signal transmission path is shortened while optimizing the spatial layout, reducing signal attenuation and delay. A shielding plate is placed between the drive board and the filter module, which can effectively suppress mutual electromagnetic interference between the two within the same cavity, further enhancing the overall EMC performance and solving the problem of insufficient shielding structure adaptation in traditional layouts. This application adopts a distributed design for the filter modules, allowing for flexible configuration of filter modules of different specifications or parameters according to the filtering requirements and signal characteristics of different circuit sections, enhancing design flexibility.

[0033] It should be noted that, in order to demonstrate the internal structure of the outer shell, Figure 1 The driver board is omitted.

[0034] It should be noted that PCBA is an abbreviation for Printed Circuit Board Assembly, and EMC is an abbreviation for Electromagnetic Compatibility.

[0035] Please refer to the following: Figures 1 to 3The electronic controller, electric drive assembly, and vehicle provided in this application will now be described. The electronic controller includes a housing 1, a filtering unit, a drive unit 3, and a shielding plate 5. The housing 1 includes a shell 101 and a partition plate 102 disposed within the shell 101. The partition plate 102 divides the shell 101 into multiple independent accommodating cavities 104 from top to bottom. The filtering unit includes multiple filtering modules 4, which are disposed within the accommodating cavities 104, and each filtering module 4 corresponds to one of the multiple accommodating cavities 104. Adjacent sets of filtering modules 4 are electrically connected. The drive unit 3 includes a drive board 301, an input terminal 302, and an output terminal 5. Terminal 303, drive board 301 and top filter module 4 are located in the same accommodating cavity 104 and are distributed at intervals with top filter module 4 in the vertical direction. Input terminal 302 is used to electrically connect drive board 301 and filter module 4 in the same accommodating cavity 104. Output terminal 303 is electrically connected to bottom filter module 4. Shielding plate 5 is disposed between drive board 301 and filter module 4 and fixed to housing 101. Shielding plate 5 is used to shield interference signals between drive board 301 and filter module 4 in the same accommodating cavity 104.

[0036] Compared with existing technologies, the electronic controller provided in this application divides the housing 101 into multiple independent accommodating cavities 104 distributed vertically by a partition plate 102. This, combined with a layout where multiple filter modules 4 are correspondingly arranged in one-to-one correspondence with the accommodating cavities 104, achieves vertical utilization of the internal space of the housing 101. This changes the space-occupying pattern of the integral layout of filter units in existing solutions, effectively solving the problem of excessive horizontal space occupation by existing integral filter units, improving the utilization rate of the internal space of the electronic controller, and effectively adapting to the development needs of miniaturization. The driver board 301 and the top filter module 4 are distributed vertically and horizontally at intervals within the same accommodating cavity 104. Combined with the electrical connection of the input terminal 302 and the output terminal 303, the signal transmission path is shortened while optimizing the spatial layout, reducing signal attenuation and delay. A shielding plate 5 is placed between the driver board 301 and the filter module 4, which can effectively suppress mutual electromagnetic interference between the two within the same accommodating cavity 104, further enhancing the overall EMC performance and solving the problem of insufficient shielding structure adaptation in traditional layouts. This application adopts a distributed design for the filter module 4, which can flexibly configure filter modules 4 with different specifications or parameters according to the filtering requirements and signal characteristics of different circuit parts, thereby enhancing the design flexibility.

[0037] Optionally, the housing 101 and the partition plate 102 can be an integral component or separate components. When the housing 101 and the partition plate 102 are separate components, they can be bolted, welded, glued, riveted or snapped together.

[0038] Optionally, holes can be made in the inner wall of the housing 101 or the partition plate 102 to realize the electrical connection between adjacent filter modules 4.

[0039] Optionally, both the partition plate 102 and the shielding plate 5 are sealed to the housing 101.

[0040] It should be noted that the filter module 4 includes a filter board 401 and a filter component 402 disposed on the filter board 401, and the filter component 402 is electrically connected to the filter board 401.

[0041] In one specific embodiment of the outer shell 1, the shell 101 and the partition plate 102 are integrally formed, and the partition plate 102 divides the inner cavity of the shell 101 into two independent receiving cavities 104. The two receiving cavities 104, on the side opposite to the partition plate 102, are respectively connected to the outside. This solution has a simple processing technology, is easy to demold, and the integrated design structure has better stability. Of course, sealing plates can be provided at the bottom and / or top of the shell 101 as needed, so that the receiving cavities 104 form a closed space to avoid interference from the external environment.

[0042] Please see Figures 1 to 2 In some embodiments, the housing 1 further includes a separation frame 2 disposed within the housing 101, the separation frame 2 and the housing 101 enclosing a shielding cavity 201, and the output terminal 303 and / or the input terminal 302 disposed within the shielding cavity 201.

[0043] This embodiment solves the problem of the input terminal 302, output terminal 303 and filter unit being distributed in the same cavity in the traditional layout by setting a separation frame 2 inside the housing 101, so that the separation frame 2 and housing 101 enclose an independent shielding cavity 201, and the input terminal 302 and / or output terminal 303 are located in the shielding cavity 201. This effectively blocks the electromagnetic interference radiation and coupling path of the input terminal 302 and output terminal 303, and further improves the overall EMC performance of the electronic controller. At the same time, the shielding cavity 201 is formed by the enclosure of the housing 101 by the separation frame 2, without occupying too much internal space. It is compatible with the vertically layered accommodating cavity 104, which ensures the reliability of the connection between the input terminal 302 and output terminal 303 and the stability of signal transmission, without affecting the optimization of the overall space utilization.

[0044] Optionally, the separation frame 2 is provided with multiple terminals, with the input terminal 302 and the output terminal 303 respectively located in the corresponding separation chamber.

[0045] Please see Figure 2 In some embodiments, the electronic controller further includes terminals 6 that electrically connect two adjacent filter modules 4, and shielding tubes 7 sleeved outside the terminals 6. The partition plate 102 has clearance holes, and the shielding tubes 7 are inserted into the clearance holes and are interference-fitted with the clearance holes.

[0046] The shielding tube 7 and the clearance hole are interference-fitted, thereby blocking electromagnetic interference leakage and coupling from the terminal 6, avoiding electromagnetic crosstalk between adjacent accommodating cavities 104 due to signal transmission, and improving the EMC performance of the electronic controller. In addition, the combination structure of the terminal 6 and the shielding tube 7 does not require complex wiring, is suitable for layered layout space design, and does not occupy too much internal space while ensuring efficient conductive connection between adjacent filter modules 4. It takes into account connection reliability, shielding effectiveness and space utilization, making the structural design of the electronic controller more in line with the development needs of high integration and miniaturization.

[0047] Optionally, the end of the shielding tube 7 abuts against the filter module 4 and is fitted with the terminal 6 with a gap, interference, or transition fit; or the shielding tube 7 is fitted with the terminal 6 with an interference fit, and the end is flush with the surface of the partition plate 102. The end of the shielding tube 7 directly abuts against the filter module 4, which not only isolates electromagnetic crosstalk between the filter modules 4 in two adjacent accommodating cavities 104, but also isolates the terminal 6 from the filter module 4, preventing electromagnetic interference between the terminal 6 and the filter module 4 and improving the electromagnetic shielding effectiveness of the terminal 6. The interference fit between the shielding tube 7 and the terminal 6 ensures a tight fit and stable fixation, effectively preventing relative displacement under vibration scenarios such as vehicle movement, ensuring the full circumference wrapping effect of the shielding tube 7 on the terminal 6, blocking the transmission path of electromagnetic interference along the terminal 6, and ensuring the stability of EMC performance.

[0048] Please see Figure 2 In some embodiments, the housing 101 includes an upper receiving area and a lower receiving area distributed from top to bottom, the cross section of the upper receiving area being adapted to the contour of the drive plate 301, and the cross section of the lower receiving area being adapted to the contour of the filter module 4.

[0049] This embodiment utilizes a "contour-fit" design to ensure a tight fit between the drive board 301 and the filter module 4 with the upper and lower receiving areas, respectively. This minimizes redundant gaps between components and the inner wall of the housing 101, avoiding wasted space and resulting in a more compact internal structure. The upper and lower receiving areas achieve a vertical stacking layout of the drive board 301 and the filter module 4, significantly reducing the lateral footprint of the device compared to the traditional horizontally distributed arrangement, thus achieving efficient use of the electronic controller's space. While ensuring the reliability of the drive board 301 and filter module 4 installation, this solution directly reduces the overall footprint of the electronic controller from a structural perspective, reserving more assembly space for peripheral components and facilitating a more rational layout of the electronic equipment.

[0050] Please see Figure 1 In some embodiments, multiple filter modules 4 are flush with one end of the drive board 301 in the vertical direction, and the other end forms a staggered distribution structure. The housing 101 is arranged to conform to the shape of the filter modules 4 and the drive board 301.

[0051] The housing 101 is designed to conform to the shape of the filter module 4 and the drive board 301, avoiding excessive lateral space occupation by the housing 101 at staggered ends due to the need to accommodate the largest components. This allows for more assembly space for peripheral components of the electronic controller, improving adaptability to the electric drive assembly and vehicle installation environment. The flush end creates a flat surface on the outer surface of the housing 101, reducing redundant space occupation and ensuring the structural compactness of the core mounting side of the electronic controller. This solution optimizes the assembly position of the drive board 301 and the filter module 4, as well as the external dimensions of the housing 101, improving internal space utilization without increasing the overall volume, aligning with the design trend of high integration and miniaturization.

[0052] It should be noted that "conformal setting" means that the inner contour of the housing 101 conforms to the outer contour of the filter module 4 and the drive board 301, that is, the housing 101 abuts against the filter module 4 and the drive board 301, or the housing 101 is clearance-fitted with the filter module 4 and the drive board 301.

[0053] Please see Figure 2 In some embodiments, the cross-sectional dimensions of the multiple filter modules 4 gradually decrease from top to bottom, and the cross-sectional dimension of the drive plate 301 is larger than that of the filter module 4, so that the lower part of the housing 101 forms a clearance area 103.

[0054] The filter module 4 features a gradient cross-section design from top to bottom, which, combined with the large-sized layout of the drive board 301, creates a compact "wider at the top and narrower at the bottom" structure for the internal components. This gradient size distribution maximizes the use of vertical space, while the clearance area 103 at the bottom of the housing 101 cleverly releases additional space, providing ample clearance for wiring harnesses, mounting brackets, or other components around the electronic controller. This significantly improves the space adaptability to the electric drive assembly and vehicle installation environment. Furthermore, the clearance area 103 effectively reduces layout conflicts between the electronic controller and surrounding components, especially in complex installation environments with limited space. It can flexibly avoid surrounding protruding structures or critical components, reducing the risk of interference during assembly.

[0055] It should be noted that "the cross-section of the filter module 4" refers to the cross-section of the filter plate 401 in the filter module 4. Since the filter component 402 is integrated into the filter plate 401, the filter plate 401 is the largest component in the filter module 4.

[0056] As not shown in the figure, in some embodiments, the housing 1 also includes a baffle disposed in the accommodating cavity 104, which divides the accommodating cavity 104 into multiple installation chambers in a transverse direction. The filter module 4 includes multiple filter modules that are electrically connected in sequence. Each installation chamber is provided with a set of filter modules, and the filter module at the first end is electrically connected to the filter module 4 above, and the filter module at the last end is electrically connected to the filter module 4 below.

[0057] The baffle horizontally divides the accommodating cavity 104 into multiple independent installation chambers, thereby separating and setting up multiple filter modules. This avoids the space congestion and interference caused by arranging multiple filter modules together, and the division into independent installation chambers ensures the orderly arrangement of each filter module. The design of one installation chamber for each filter module allows for precise matching of installation space according to the functional requirements and size specifications of the filter modules, avoiding redundant space waste. At the same time, the horizontally separated structure does not affect the vertical connection of the upper and lower filter modules 4. The precise electrical connection between the first and last filter modules ensures the regularity and continuity of the signal transmission path, achieving synergy between horizontal space optimization and vertical functional connection.

[0058] It should be noted that "horizontal" refers to a path perpendicular to the vertical direction. "The first filtering module" refers to a group located at the end of a group of horizontally distributed filtering modules, while "the last end" refers to the other end relative to the first end.

[0059] It should be noted that in this embodiment, the filter module 4 is split into multiple filter modules for the purpose of facilitating assembly and space utilization. Each filter module includes a filter board 401 and a filter component 402 integrated into the filter board 401.

[0060] Please see Figures 1 to 3 In some embodiments, the top and / or bottom of the housing 101 are provided with assembly openings, and the housing 1 also includes a shielding cover 8 covering the assembly openings.

[0061] The top and / or bottom mounting openings provide ample operating space for the installation of core components such as the internal filter module 4 and drive board 301, avoiding the space limitations imposed by the traditional enclosed housing 101 on component assembly. This reduces the assembly difficulty of multi-layered components and facilitates precise positioning of each module and connector. The detachable design of the shielding cover 8 allows direct access to the target component simply by opening the corresponding opening, improving maintenance efficiency and reducing the impact on surrounding assembly structures. Furthermore, the shielding cover 8 not only forms a tight seal around the mounting opening, filling the electromagnetic leakage path at the opening, but also enhances the electromagnetic isolation effect of the internal chamber, ensuring the EMC performance stability of the electronic controller in high-frequency, highly integrated scenarios, achieving a synergistic improvement in assembly convenience, space utilization, and shielding reliability.

[0062] Optionally, the shielding cover 8 is snap-fitted or screwed onto the housing 101.

[0063] Based on the same inventive concept, embodiments of this application also provide an electric drive assembly. The vehicle includes the aforementioned electronic controller.

[0064] The electric drive assembly provided by this utility model adopts the aforementioned electronic controller. Using this electric drive assembly, the housing 101 is divided into multiple independent accommodating cavities 104 distributed vertically by a partition plate 102. This, along with a layout where multiple filter modules 4 are correspondingly arranged in one-to-one correspondence with the accommodating cavities 104, achieves vertical utilization of the internal space of the housing 101. This changes the space-occupying pattern of the integral layout of the filter unit in existing solutions, effectively solving the problem of excessive horizontal space occupation by existing integral filter units, improving the utilization rate of the internal space of the electronic controller, and effectively adapting to the development needs of miniaturization. The drive board 301 and the top filter module 4 are distributed vertically and horizontally at intervals within the same accommodating cavity 104. Combined with the electrical connection of the input terminal 302 and the output terminal 303, the signal transmission path is shortened while optimizing the spatial layout, reducing signal attenuation and delay. A shielding plate 5 is set between the drive board 301 and the filter module 4, which can effectively suppress mutual electromagnetic interference between the two within the same accommodating cavity 104, further enhancing the overall EMC performance and solving the problem of insufficient shielding structure adaptation in traditional layouts. This application adopts a distributed design for the filter module 4, which can flexibly configure filter modules 4 with different specifications or parameters according to the filtering requirements and signal characteristics of different circuit parts, thereby enhancing the design flexibility.

[0065] Based on the same inventive concept, this application also provides a vehicle. The vehicle includes the above-described electric drive assembly.

[0066] The vehicle provided by this utility model adopts the aforementioned electric drive assembly. This assembly divides the housing 101 into multiple independent accommodating cavities 104 distributed vertically via a partition plate 102. This, combined with a layout where multiple filter modules 4 are correspondingly arranged in one-to-one correspondence with the accommodating cavities 104, achieves vertical utilization of the internal space of the housing 101. This changes the space-occupying pattern of the integral layout of the filter unit in existing solutions, effectively solving the problem of excessive lateral space occupation by existing integral filter units, improving the utilization rate of the internal space of the electronic controller, and effectively adapting to the development needs of miniaturization. The drive board 301 and the top filter module 4 are distributed vertically and horizontally at intervals within the same accommodating cavity 104. Combined with the electrical connection of the input terminal 302 and the output terminal 303, the signal transmission path is shortened while optimizing the spatial layout, reducing signal attenuation and delay. A shielding plate 5 is set between the drive board 301 and the filter module 4, which can effectively suppress mutual electromagnetic interference between the two within the same accommodating cavity 104, further enhancing the overall EMC performance and solving the problem of insufficient shielding structure adaptation in traditional layouts. This application adopts a distributed design for the filter module 4, which can flexibly configure filter modules 4 with different specifications or parameters according to the filtering requirements and signal characteristics of different circuit parts, thereby enhancing the design flexibility.

[0067] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
