[0035] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] The following is for reference. Figures 1-3 An integrated filtering component 10 according to an embodiment of the first aspect of the present invention is described.

[0037] like Figures 1-3 As shown, the integrated filter assembly 10 according to a first aspect embodiment of the present invention includes: a magnetic ring 12, a filter circuit board 17, and a heat exchanger. The magnetic ring 12 and the filter circuit board 17 are in a first direction (e.g., Figure 1 The magnetic ring 12 and the filter circuit board 17 are arranged at intervals (as shown in the vertical direction); at least part of the heat exchanger is disposed between the magnetic ring 12 and the filter circuit board 17, and the heat exchanger is used to exchange heat and cool the magnetic ring 12 and the filter circuit board 17.

[0038] In this embodiment, the integrated filter component 10 includes a magnetic ring 12 and a filter circuit board 17. The magnetic ring 12 can absorb high-frequency noise and enhance the anti-interference capability of the circuit, thus meeting the filtering needs of the integrated filter component 10. The filter circuit board 17 can work with the magnetic ring 12 to achieve the filtering function. Since the filter circuit board 17 is smaller in size than the magnetic ring 12, the magnetic ring 12 can be made smaller under the same filtering requirements, thereby reducing the dependence of the integrated filter component 10 on the magnetic ring 12, making the overall size of the integrated filter component 10 smaller, and making the overall structure of the integrated filter component 10 more compact.

[0039] In this embodiment, the magnetic ring 12 and the filter circuit board 17 are arranged at a distance in the first direction. At least part of the heat exchanger is disposed between the magnetic ring 12 and the filter circuit board 17. The heat exchanger performs heat exchange and cooling on the magnetic ring 12 and the filter circuit board 17. The structure is simple and the arrangement is reasonable. The heat exchanger located between the magnetic ring 12 and the filter circuit board 17 can perform heat exchange and cooling on the magnetic ring 12 and the filter circuit board 17 at the same time. This can effectively reduce the number of heat exchangers. The heat exchanger structure used for cooling occupies less space in the integrated filter assembly 10, thereby making the integrated filter assembly 10 smaller in overall size and more compact in overall structure while operating stably and reliably.

[0040] According to the embodiment of the present invention, the integrated filter assembly 10, by setting a magnetic ring 12 and a filter circuit board 17, at least a portion of the heat exchange component is disposed between the magnetic ring 12 and the filter circuit board 17, so that the volume of the magnetic ring 12 is smaller, and the heat exchange component can simultaneously exchange heat and cool the magnetic ring 12 and the filter circuit board 17, thereby making the overall volume of the integrated filter assembly 10 smaller and the overall structure more compact.

[0041] In some embodiments of the present invention, such as Figure 2 As shown, the heat exchanger may include a liquid cooling pipe 16 having a cooling channel, at least a portion of which is located between the magnetic ring 12 and the filter circuit board 17.

[0042] In this embodiment, the heat exchanger includes a liquid cooling pipe 16. The cooling channel of the liquid cooling pipe 16 is at least partially located between the magnetic ring 12 and the filter circuit board 17. The structure is simple, and the cooling fluid can flow along the cooling channel in the liquid cooling pipe 16 and carry away the heat generated by the magnetic ring 12 and the filter circuit board 17 during operation. The cooling effect is good, so that the magnetic ring 12 and the filter circuit board 17 can be cooled well at the same time, thereby enabling the integrated filter assembly 10 to operate more stably and reliably.

[0043] In one embodiment of the present invention, such as Figure 2 As shown, the liquid cooling tube 16 can be wound around the outside of the magnetic ring 12.

[0044] In this embodiment, the liquid cooling pipe 16 is wound around the outside of the magnetic ring 12, which can make the liquid cooling pipe 16 and the magnetic ring 12 have a larger heat exchange mating surface, so that the liquid cooling pipe 16 can better cover all positions of the magnetic ring 12, and the magnetic ring 12 can get more sufficient heat exchange and cooling, thereby improving the operational stability and reliability of the integrated filter component 10.

[0045] In one embodiment of the present invention, such as Figure 2 As shown, the magnetic ring 12 can be wound around along the second direction (e.g. Figure 2 The axis extending in the front-back direction (as shown) extends in a ring shape, and the liquid cooling pipe 16 extends along a spiral line in the axial direction of the magnetic ring 12, with the second direction intersecting the first direction.

[0046] In this embodiment, the magnetic ring 12 extends in a ring shape around the axis extending along the second direction. The filter circuit board 17 is arranged on one side of the radial direction of the magnetic ring 12 in the first direction, which makes it more convenient and easier to connect the filter circuit board 17 and the magnetic ring 12 in the circuit. This allows the liquid cooling pipe 16 to be conveniently wound around the outside of the magnetic ring 12 when it is partially located between the magnetic ring 12 and the filter circuit board 17.

[0047] The intersection of the first and second directions is intended to illustrate that the first and second directions can be arranged perpendicularly or only intersecting, not perpendicularly. In this embodiment, the liquid cooling pipe 16 extends along a spiral line in the axial direction of the magnetic ring 12. This simple structure allows the liquid cooling pipe 16 to be easily wound around the outer periphery of the magnetic ring 12, and ensures that the liquid cooling pipe 16 can effectively cover the extension range of the magnetic ring 12 in the second direction, thus providing more thorough cooling to the magnetic ring 12. Optionally, the magnetic ring 12 can be an oblong ring, extending entirely along a third direction. This reduces the size of the magnetic ring 12 in the first direction, allowing for a more compact arrangement of the filter circuit board 17, the magnetic ring 12, and the liquid cooling pipe 16.

[0048] In some examples of the present invention, references Figure 2 As shown, there can be multiple magnetic rings 12, and the number of turns of the liquid cooling tube 16 around the outer periphery of a single magnetic ring 12 is greater than or equal to 2 turns.

[0049] In this embodiment, multiple magnetic rings 12 are provided to meet the usage and operation requirements of the integrated filter component 10. The number of turns of the liquid cooling pipe 16 around the outer periphery of each magnetic ring 12 is set to be greater than or equal to 2 turns, so that the liquid cooling pipe 16 and each magnetic ring 12 can have sufficient heat exchange contact area. This allows the liquid cooling pipe 16 to effectively meet the cooling and heat dissipation requirements of the magnetic ring 12, and enables the liquid cooling pipe 16 to provide a good cooling effect for each magnetic ring 12. For example, the number of turns of the liquid cooling pipe 16 around the outer periphery of each magnetic ring 12 can be 2 turns, 3 turns, 4 turns, etc. The number of turns of the liquid cooling pipe 16 around each magnetic ring 12 can be reasonably set according to the cooling requirements of the magnetic ring 12 and the size of the liquid cooling pipe 16.

[0050] In one embodiment of the present invention, reference is made to... Figure 1 and Figure 2 As shown, in the first direction, the portion of the liquid cooling pipe 16 located between the magnetic ring 12 and the filter circuit board 17 is formed as a first cooling section, and the gap between the first cooling section and the filter circuit board 17 is less than or equal to 3 mm.

[0051] In this embodiment, the gap between the first cooling section and the filter circuit board 17 is set to be less than or equal to 3mm, which allows the first cooling section and the filter circuit board 17 to have a smaller gap, so that the liquid cooling pipe 16 can have a good cooling effect on the filter circuit board 17, and makes the overall structure of the liquid cooling pipe 16, the filter circuit board 17 and the magnetic ring 12 more compact, which to a certain extent makes the overall size of the integrated filter component 10 smaller.

[0052] In one embodiment of the present invention, reference is made to... Figure 2 As shown, there can be multiple magnetic rings 12, which are arranged at intervals along the second direction. Liquid cooling pipes 16 are wound around the outer periphery of the multiple magnetic rings 12. Alternatively, there can be multiple liquid cooling pipes 16, which are arranged in a one-to-one correspondence with the multiple magnetic rings 12.

[0053] In this embodiment, multiple magnetic rings 12 are arranged at intervals along the second direction. The structure is simple and the arrangement is reasonable, which facilitates the circuit connection and arrangement of the integrated filter component 10.

[0054] In this embodiment, the liquid cooling pipe 16 is wound around the outer periphery of multiple magnetic rings 12, so only one liquid cooling pipe 16 can be wound on the multiple magnetic rings 12. This reduces the number of liquid cooling pipes 16, thereby reducing the number of cooling channel inlets and outlets, and further reducing the arrangement of corresponding connecting pipes. This makes the heat exchanger occupy less space in the integrated filter assembly 10, thus making the overall volume of the integrated filter assembly 10 smaller.

[0055] In this embodiment, multiple liquid cooling pipes 16 can be provided, and multiple liquid cooling pipes 16 are arranged in a one-to-one correspondence with multiple magnetic rings 12. This allows each liquid cooling pipe 16 to cool and dissipate heat from a single magnetic ring 12, thereby avoiding the gradual decrease in cooling effect that occurs when a liquid cooling pipe 16 is wrapped around multiple magnetic rings 12. As a result, each magnetic ring 12 can obtain a good heat exchange and cooling effect, and the operational stability and reliability of the integrated filter component 10 are improved.

[0056] In this embodiment, the arrangement of the liquid cooling pipe 16 and the magnetic ring 12 can be flexibly arranged as needed. For example, in some examples of the present invention, one liquid cooling pipe 16 can also be wound around multiple magnetic rings 12, and multiple liquid cooling pipes 16 can work together to cool all the magnetic rings 12, so as to reduce the number of liquid cooling pipes 16 while making the magnetic rings 12 achieve a good cooling effect. These examples will not be listed here.

[0057] In some embodiments of the present invention, such as Figure 2 As shown, the number of magnetic rings 12 can be multiple, and the multiple magnetic rings 12 are arranged at intervals along the second direction. The integrated filter assembly 10 may also include conductive elements 13, which extend along the second direction and pass through the inner side of the multiple magnetic rings 12. The number of conductive elements 13 is two, and the two conductive elements 13 are in a third direction (e.g., Figure 2 The filter circuit board 17 is arranged at intervals in the left and right directions as shown, and the third direction intersects the first and second directions in pairs. The filter circuit board 17 is electrically connected to the two conductive parts 13.

[0058] In this embodiment, the intersection of the third direction with the first direction and the second direction is intended to illustrate that the third direction and the first direction can be arranged perpendicularly or only intersecting and not perpendicularly. The third direction and the second direction can be arranged perpendicularly or only intersecting and not perpendicularly. The first direction and the second direction can be arranged perpendicularly or only intersecting and not perpendicularly.

[0059] In this embodiment, the integrated filter assembly 10 is further provided with two conductive elements 13. The two conductive elements 13 pass through the inner side of multiple magnetic rings 12 along the second direction and are electrically connected to the filter circuit board 17. The structure is simple and can well meet the circuit connection and filter circuit layout requirements in the integrated filter assembly 10, so that the circuit board and magnetic rings 12 can cooperate well to perform filtering operations. Optionally, the conductive element 13 can be a conductive plate, which can provide a larger connection arrangement space when the conductive plate is connected to other conductive components or electrical components, thereby facilitating assembly and connection.

[0060] In one embodiment of the present invention, such as Figure 2 As shown, the integrated filter assembly 10 may also include a first connector 14, and two conductive elements 13 are electrically connected to the filter circuit board 17 through the first connector 14.

[0061] In this embodiment, the integrated filter component 10 is provided with a first connector 14. The first connector 14 electrically connects the two conductive elements 13 to the circuit board. The structure is simple and can well meet the electrical connection requirements between the conductive elements 13 and the filter circuit board 17. Optionally, the first connector 14 can be a connecting copper busbar. There can be two first connectors 14 arranged in a one-to-one correspondence with the two conductive elements 13, so that the two conductive elements 13 can be electrically connected to the filter circuit board 17 respectively through the first connector. Optionally, the first connector 14 can be a connecting copper busbar.

[0062] In one embodiment of the present invention, such as Figure 2 As shown, the integrated filter assembly 10 may further include a second connector 15, which extends along a first direction. In a second direction, the second connector 15 is disposed between two adjacent magnetic rings 12, and one of the two conductive members 13 is electrically connected to the filter circuit board 17 through the second connector 15.

[0063] In this embodiment, the integrated filter assembly 10 further includes a second connector 15. The second connector 15 extends along a first direction, facilitating connection with the filter circuit board 17 and conductive plate arranged in the first direction. One of the two conductive members 13 is electrically connected to the filter circuit board 17 via the second connector 15. The second connector 15 is disposed between two adjacent magnetic rings 12, satisfying the circuit connection and arrangement requirements in the integrated filter assembly 10, enabling the multiple magnetic rings 12 and the filter circuit board 17 to stably perform filtering, thereby meeting the operational requirements of the integrated filter assembly 10. Optionally, the second connector 15 can be a conductive post, and the second connector 15 can be securely connected to the filter circuit board 17, facilitating the assembly of the second connector 15 and the filter circuit board 17.

[0064] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the integrated filter component 10 may further include: a first capacitor 18 and a second capacitor 19. The first capacitor 18 is used for protection circuits and is disposed on and electrically connected to the filter circuit board 17. The second capacitor 19 is used for filtering and is disposed on and electrically connected to the filter circuit board 17.

[0065] In this embodiment, the integrated filter component 10 is provided with a first capacitor 18 and a second capacitor 19. The first capacitor 18 is used for circuit protection, and the second capacitor 19 is used for filtering. The structure is simple and can well meet the needs of stable operation and filtering of the integrated filter component 10.

[0066] In this embodiment, both the first capacitor 18 and the second capacitor 19 are disposed on and electrically connected to the filter circuit board 17, resulting in a simple structure and a more compact overall structure of the first capacitor 18, the second capacitor 19, and the filter circuit board 17, thus making the integrated filter assembly 10 smaller and more compact. Optionally, the first capacitor 18 and the second capacitor 19 can be integrated on the filter circuit board 17, which simplifies the assembly process and makes the integrated filter assembly 10 more efficient during assembly.

[0067] In some embodiments of the present invention, such as Figure 1 As shown, the integrated filter assembly 10 may also include a housing 11, with the filter circuit board 17 and the magnetic ring 12 both disposed in the housing 11, and the filter circuit board 17 and the magnetic ring 12 being injection molded into a single piece through the housing 11.

[0068] In this embodiment, the integrated filter assembly 10 also includes a housing 11. The filter circuit board 17 and the magnetic ring 12 are both disposed in the housing 11. The structure is simple. The housing 11 can provide good protection for the filter circuit board 17 and the magnetic ring 12, and facilitate the assembly and arrangement of the filter circuit board 17 and the magnetic ring 12. The filter circuit board 17 and the magnetic ring 12 are injection molded into a single piece through the housing 11, which can make the positional relationship between the filter circuit board 17 and the magnetic ring 12 more stable, and make the integrated filter assembly 10 more convenient and efficient in production and processing, making the overall structure of the integrated filter assembly 10 more compact and better integrated.

[0070] like Figures 1-3 As shown, the motor controller according to an embodiment of the present invention includes an integrated filter component 10 according to a first aspect of the present invention.

[0071] Other configurations and operations of the motor controller according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0072] According to the motor controller of the present invention, by providing the integrated filter component 10 of the first aspect embodiment, the integrated filter component 10 is provided with a magnetic ring 12 and a filter circuit board 17, and at least part of the heat exchange component is provided between the magnetic ring 12 and the filter circuit board 17, so that the magnetic ring 12 is smaller in size, and the heat exchange component can simultaneously exchange heat and cool the magnetic ring 12 and the filter circuit board 17, thereby making the overall size of the integrated filter component 10 smaller and the overall structure more compact.

[0073] The following is for reference. Figures 1-3 An electric drive assembly according to an embodiment of a third aspect of the present invention is described.

[0074] like Figures 1-3 As shown, the electric drive assembly according to an embodiment of the present invention includes a motor controller according to a second aspect of the present invention.

[0075] Other configurations and operations of the electric drive assembly according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0076] According to the electric drive assembly of the present invention, by providing the motor controller of the second aspect embodiment described above, and by providing the magnetic ring 12 and the filter circuit board 17, at least a portion of the heat exchange component is disposed between the magnetic ring 12 and the filter circuit board 17, so that the volume of the magnetic ring 12 is smaller, and the heat exchange component can simultaneously exchange heat and cool the magnetic ring 12 and the filter circuit board 17, thereby making the overall volume of the integrated filter assembly 10 smaller and the overall structure more compact.

[0077] The following is for reference. Figures 1-3 A vehicle according to an embodiment of the fourth aspect of the present invention is described.

[0078] like Figures 1-3 As shown, the vehicle according to an embodiment of the present invention includes an electric drive assembly according to a third aspect of the present invention.

[0079] Other configurations and operations of the vehicle according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0080] According to the vehicle of the present invention, by providing the electric drive assembly of the third aspect embodiment described above, by providing the magnetic ring 12 and the filter circuit board 17, at least a portion of the heat exchange component is disposed between the magnetic ring 12 and the filter circuit board 17, so that the volume of the magnetic ring 12 is smaller, and the heat exchange component can simultaneously exchange heat and cool the magnetic ring 12 and the filter circuit board 17, thereby making the overall volume of the integrated filter assembly 10 smaller and the overall structure more compact.

[0081] The following will refer to Figures 1-3 A vehicle according to a specific embodiment of the present invention is described.

[0082] like Figures 1-3 As shown, the vehicle includes an electric drive assembly, which includes a motor controller, and the motor controller has an integrated filter component 10.

[0083] The integrated filter assembly 10 includes a housing 11, a filter circuit board 17, a magnetic ring 12, a heat exchanger, a conductive component 13, a first connector 14, a second connector 15, a first capacitor 18, and a second capacitor 19. The filter circuit board 17 and the magnetic ring 12 are arranged at intervals in a first direction. The filter circuit board 17 extends along a third direction and has a first capacitor 18 at one end. The first capacitor 18 is a safety capacitor. The filter circuit board 17 has multiple second capacitors 19, which are arranged at intervals along a third direction. The second capacitors 19 are Y-type capacitors. There are two magnetic rings 12, which are spaced apart along the second direction. There are also two conductive plates 13, which extend along the second direction and are spaced apart in the third direction. The two conductive plates pass through the inner sides of the two magnetic rings 12. There are two first connectors 14, which are copper busbars, located on the outermost sides of the two magnetic rings 12 in the second direction. For example, the first connectors 14 can be bent in the second direction to avoid the magnetic rings 12 and stably connect to the filter circuit board 17 and the conductive plates 13. The two conductive plates 13 are electrically connected to the filter circuit board 17 via the two first connectors 14.

[0084] The second connector 15 is a conductive post, positioned between the two magnetic rings 12 in the second direction. The second connector extends along the first direction and its two ends are respectively connected to and electrically connected to the filter circuit board 17 and a conductive element 13. The heat exchange component includes a liquid cooling tube 16, which is made of plastic. There is one liquid cooling tube 16, which is wound around the outer periphery of the two magnetic rings 12 along the first direction, with two turns around each magnetic ring 12.

[0085] During the assembly of the integrated filter assembly 10, the first capacitor 18 and the second capacitor 19 can be pre-welded together with the filter circuit board 17 before being assembled with the magnetic ring 12, etc., thereby simplifying the assembly process and facilitating the inspection and maintenance of the first capacitor 18 and the second capacitor 19. This makes the overall structure of the first capacitor 18, the second capacitor 19, and the filter circuit board 17 more compact, thus allowing for more flexible arrangement of the first capacitor 18 and the second capacitor 19 to a certain extent. The conductive posts and the filter circuit board 17 can be fastened together with screws to form a circuit connection. The liquid cooling pipe 16 is wound around the two magnetic rings 12. The filter circuit board 17 and the magnetic rings 12 and other components are integrally injection molded to form a housing 11, which can provide stable and reliable fixed support for the magnetic rings 12 and other components. This allows for better overall integration of the integrated filter assembly 10, making the assembly of the integrated filter assembly 10 more convenient and easier.

[0086] In this embodiment, a magnetic ring 12 and a filter circuit board 17 are provided, so that the volume of the magnetic ring 12 is smaller under the same filtering requirements. At least part of the heat exchanger is provided between the magnetic ring 12 and the filter circuit board 17, so that the heat exchanger can simultaneously exchange heat and cool the magnetic ring 12 and the filter circuit board 17, thereby making the overall volume of the integrated filter component 10 smaller and the overall structure more compact.
