[0001] This application claims priority to Chinese patent applications filed on December 24, 2024, with application number 202411944489.8, and on December 27, 2024, with application number 202411979521.6, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of controller technology, specifically to an electronic device, an electronic control module, a controller, and a vehicle. Background Technology

[0003] Electronic devices, such as power modules and capacitor modules, are important components in electronic systems that enable electrical functions. As conductors, electronic devices generate inductance and magnetic fields when current flows through them, resulting in stray inductance. Technical issues

[0004] Currently, electronic devices generate significant stray inductance, leading to unstable operation. Technical solutions

[0005] In a first aspect, this application provides an electronic device, including: a first connecting terminal;

[0006] The second connecting terminal has the opposite polarity to the first connecting terminal and is spaced apart from the first connecting terminal. In a projection plane perpendicular to the thickness direction of the second connecting terminal, the projection of the first connecting terminal falls into the projection of the second connecting terminal.

[0007] Secondly, this application also provides an electronic control module. The electronic control module includes a housing, and at least two of a capacitor module, a relay, and a fuse are disposed within the housing, wherein the capacitor module is an electronic device as described in the first aspect.

[0008] Thirdly, this application also provides a controller. The controller includes a housing with a receiving portion;

[0009] The electronic control module as described in the second aspect is disposed within the receiving portion.

[0010] Fourthly, this application also provides a vehicle including the electronic device as described in the first aspect, the electronic control module as described in the second aspect, or the controller as described in the third aspect. Beneficial effects

[0011] The electronic device provided in this application arranges the first and second connecting terminals such that, in a projection plane perpendicular to the thickness direction of the second connecting terminal, the projection of the first connecting terminal falls within the projection of the second connecting terminal. Compared to arranging them side by side along the length or width of the connecting terminals, this allows the centers of the first and second connecting terminals to be closer together. This ensures that during energization, the overlapping portions of the magnetic fields around the first and second connecting terminals cancel each other out due to their opposite directions. This helps reduce stray inductance and improve the stability of the electronic device's operation. Attached Figure Description

[0046] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0047] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, where the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, where the first feature is at a lower horizontal level than the second feature.

[0048] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for distinction in description and have no special meaning.

[0049] This application provides an electronic device 20a. The electronic device 20a can be a capacitor module 20 or a power module 30 in a controller 100.

[0050] Referring to Figures 1, 2 and 4, the electronic device 20a includes a first connection terminal 211a and a second connection terminal 221b.

[0051] The second connecting terminal 221b has the opposite polarity to the first connecting terminal 211a and is spaced apart from the first connecting terminal 211a. In the projection plane perpendicular to the thickness direction of the second connecting terminal 221b, the projection of the first connecting terminal 211a falls into the projection of the second connecting terminal 221b.

[0052] It can be understood that the second connecting terminal 221b and the first connecting terminal 211a are arranged at intervals along the thickness direction of the second connecting terminal 221b, and overlap with the first connecting terminal 211a along the thickness direction of the second connecting terminal 221b. The second connecting terminal 221b and the first connecting terminal 211a are stacked together. For example, as shown in Figures 1 and 2, the first connecting terminal 211a is disposed above the second connecting terminal 221b.

[0053] Because the first connecting terminal 211a and the second connecting terminal 221b have opposite polarities, when the electronic device 20a is energized, the current directions of the first connecting terminal 211a and the second connecting terminal 221b are opposite, and the magnetic field directions around the first connecting terminal 211a and the second connecting terminal 221b are also opposite. Referring to Figure 3, typically, the first connecting terminal 211a and the second connecting terminal 221b are arranged side by side along the length direction of the first connecting terminal 211a, and the center distance between the first connecting terminal 211a and the second connecting terminal 221b is large. When the electronic device 20a is energized, the magnetic field directions at the point where the magnetic fields around the first connecting terminal 211a and the second connecting terminal 221b overlap (position E in the figure) are the same, resulting in magnetic field superposition, which in turn leads to an increase in stray inductance.

[0054] In this embodiment, by arranging the first connecting terminal 211a and the second connecting terminal 221b such that the projection of the first connecting terminal 211a falls within the projection of the second connecting terminal 221b in a projection plane perpendicular to the thickness direction of the second connecting terminal 221b, compared to arranging them side by side along the length or width of the connecting terminal, the center of the first connecting terminal 211a and the center of the second connecting terminal 221b can be closer together. This allows the overlapping portion of the magnetic field around the first connecting terminal 211a and the magnetic field around the second connecting terminal 221b (position F in Figure 4) to partially cancel each other out due to the opposite directions of the magnetic fields during the energizing process. This helps to reduce stray inductance and improve the stability of the operation of the electronic device 20a.

[0055] In some embodiments, the first connecting terminal 211a and the second connecting terminal 221b are arranged side by side along their thickness direction (Z direction in the figure), with the first connecting terminal 211a parallel to the second connecting terminal 221b. It can be understood that the thickness direction (Z direction in the figure) of the first connecting terminal 211a is parallel to the thickness direction of the second connecting terminal 221b. This arrangement brings the centers of the first connecting terminal 211a and the second connecting terminal 221b closer together, so that the magnetic fields around the first connecting terminal 211a and the second connecting terminal 221b can largely cancel each other out, thus helping to significantly reduce stray inductance.

[0056] In some embodiments, the length of the first connecting terminal 211a is the same as the length of the second connecting terminal 221b, which helps to align the first connecting terminal 211a and the second connecting terminal 221b in the length direction.

[0057] In some embodiments, the width of the first connecting terminal 211a is smaller than the width of the second connecting terminal 221b. Along the width direction of the first connecting terminal 211a (X direction in the figure), the free end of the second connecting terminal 221b extends beyond the free end of the first connecting terminal 211a. This arrangement facilitates the connection of the first connecting terminal 211a and the second connecting terminal 221b to other electrical connectors, reducing the assembly difficulty of the electronic device 20a with other components.

[0058] For example, as shown in FIG1, along the length direction (Y direction in the figure) of the first electrical connector 60, the free ends of the first connecting terminal 211a and the second connecting terminal 221b are respectively aligned. Along the width direction of the first connecting terminal 211a, the free end of the second connecting terminal 221b extends beyond the free end of the first connecting terminal 211a, so that the free ends of the first connecting terminal 211a and the free ends of the second connecting terminal 221b are misaligned.

[0059] In some embodiments, the electronic device 20a further includes an insulating element 40a.

[0060] The insulating element 40a is at least partially disposed between the first connection terminal 211a and the second connection terminal 221b to reduce the risk of short circuit between the first connection terminal 211a and the second connection terminal 221b.

[0061] In some embodiments, along the thickness direction (Z direction in the figure) of the insulating member 40a, the insulating member 40a has a first surface and a second surface disposed opposite to each other. The first surface is in contact with the first connecting terminal 211a, and the second surface is in contact with the second connecting terminal 221b. This arrangement further reduces the distance between the first connecting terminal 211a and the second connecting terminal 221b, thereby bringing the centers of the first connecting terminal 211a and the second connecting terminal 221b closer together. This helps to further cancel out the magnetic fields around the first connecting terminal 211a and the second connecting terminal 221b, reducing stray inductance.

[0062] Referring to Figures 1 and 2, in some embodiments, along the length direction of the insulating member 40a (Y direction in the figure), the length of the insulating member 40a is greater than the length of the first connecting terminal 211a, and the free end of the insulating member 40a extends beyond the free end of the first connecting terminal 211a, which helps to improve the insulation reliability between the first connecting terminal 211a and the second connecting terminal 221b.

[0063] In other embodiments, along the length direction of the insulating member 40a, the length of the insulating member 40a may be equal to the length of the first connecting terminal 211a, and the free end of the insulating member 40a is flush with the end of the first connecting terminal 211a, so as to reduce the length of the insulating member 40a.

[0064] In some embodiments, the width of the insulating member 40a is greater than the width of the first connecting terminal 211a. Along the width direction of the insulating member 40a (X direction in the figure), the free end of the insulating member 40a extends beyond the free end of the first connecting terminal 211a, which helps to improve the insulation reliability between the first connecting terminal 211a and the second connecting terminal 221b.

[0065] In some embodiments, the insulating member 40a includes a first insulating portion 41 and a second insulating portion 42. The first insulating portion 41 is disposed between the first connecting terminal 211a and the second connecting terminal 221b, and the second insulating portion 42 protrudes from the side of the first insulating portion 41 facing the first connecting terminal 211a and is located outside the first connecting terminal 211a.

[0066] For example, as shown in FIG1, the first insulating part 41 is horizontally disposed, and the second insulating part 42 is vertically disposed along the thickness direction of the insulating member 40a, and the second insulating part 42 is located outside the first connecting terminal 211a.

[0067] In this embodiment of the application, by providing a second insulating part 42, the creepage distance between the first connecting terminal 211a and the second connecting terminal 221b is increased, which helps to reduce the safety hazards caused by arcing of the first connecting terminal 211a and the second connecting terminal 221b under high voltage.

[0068] In some embodiments, the second insulating portion 42 protrudes from the side of the first connecting terminal 211a opposite to the second connecting terminal 221b. This further increases the creepage distance between the first connecting terminal 211a and the second connecting terminal 221b.

[0069] It is understood that, along the thickness direction of the first connecting terminal 211a, the second insulating portion 42 is higher than the first connecting terminal 211a.

[0070] Referring to Figure 1, in some embodiments, electronic device 20a is capacitor module 20, first connection terminal 211a is first output terminal 211 of capacitor module 20, and second connection terminal 221b is second output terminal 221 of capacitor module 20. The first output terminal 211 can be electrically coupled to the first input terminal 31 of power module 30, and the second output terminal 221 can be electrically coupled to the second input terminal 32 of power module 30.

[0071] In some embodiments, the insulating member 40a is provided with a first positioning part 43, which is configured to position the first output terminal 211 to reduce the risk of unstable electrical connection caused by displacement of the first output terminal 211.

[0072] In some embodiments, the first positioning part 43 is a protrusion protruding from the self-insulating member 40a, and the first connecting terminal 211a is provided with a mating hole corresponding to the first positioning part 43, and the first positioning part 43 is confined within the mating hole.

[0073] In other embodiments, the first positioning part 43 may be a latching protrusion disposed on the edge of the insulating member 40a, and the insulating member 40a is latched to the edge of the first output terminal 211 by the first positioning part 43 to position the first output terminal 211.

[0074] In some embodiments, the insulating member 40a is provided with a second positioning part 44, which is configured to position the second output terminal 221 to reduce the risk of electrical connection instability caused by displacement of the second output terminal 221.

[0075] In some embodiments, the second positioning part 44 is a protrusion protruding from the self-insulating member 40a, and the second connecting terminal 221b is provided with a mating hole corresponding to the second positioning part 44, and the second positioning part 44 is confined within the mating hole.

[0076] In other embodiments, the second positioning part 44 may be a latching protrusion provided on the edge of the insulating member 40a, and the insulating member 40a is latched to the edge of the second output terminal 221 by the second positioning part 44 to position the second output terminal 221.

[0077] The first positioning part 43 and the second positioning part 44 can have the same structure, or they can be set differently as needed.

[0078] Referring to Figure 2, in some embodiments, electronic device 20a is power module 30, first connection terminal 211a is first input terminal 31 of power module 30, and second connection terminal 221b is second input terminal 32 of power module 30. The first input terminal 31 can be used for electrical coupling with the first output terminal 211 of capacitor module 20, and the second input terminal 32 can be used for electrical coupling with the second output terminal 221 of capacitor module 20.

[0079] In some embodiments, multiple first input terminals 31 are provided, spaced apart along their length direction; multiple second input terminals 32 are provided, spaced apart along their length direction; each first input terminal 31 corresponds to each second input terminal 32. It can be understood that there is a one-to-one correspondence between the first input terminal 31 and the second input terminal 32.

[0080] For example, as shown in FIG2, three first input terminals 31 and second input terminals 32 are provided.

[0081] In some embodiments, the insulating element 40a is located between two adjacent first input terminals 31 and / or two adjacent second input terminals 32 to insulate the connected two first input terminals 31 and / or the connected two second input terminals 32, which helps the power module 30 to operate stably.

[0082] According to a second aspect of this application, this application also provides an electronic control module 1000, please refer to Figures 5 and 6 together.

[0083] The electronic control module 1000 can be applied to various controllers that include capacitors, such as motor controllers and high-voltage power distribution controllers. In this embodiment, the electronic control module 1000 is mainly described as being installed within a motor controller. However, it should be understood that applying the electronic control module 1000 to a motor controller is not a limitation on the application scope of the electronic control module 1000.

[0084] The electronic control module 1000 includes a housing 1100, a capacitor module 20, a relay 1300, and a fuse 1400. The housing 1100 is a metal housing, which improves the overall heat dissipation of the electronic control module 1000. The housing 1100 has a receiving cavity 1110, within which at least two of the capacitor module 20, relay 1300, and fuse 1400 are integrated. Integrating at least two of the capacitor module 20, relay 1300, and fuse 1400 into the receiving cavity 1110 of the housing 1100 improves the heat dissipation of at least two of the three components. Compared to traditional technologies, firstly, the plastic housing is replaced with housing 1100, which utilizes the superior thermal conductivity of metal compared to plastic to improve the heat conduction effect within the receiving cavity 1110. Secondly, at least two of the capacitor module 20, relay 1300, and fuse 1400 are integrated within the receiving cavity 1110, eliminating the need for separate plastic housings for insulation and installation of at least two of the capacitor module 20, relay 1300, and fuse 1400. This reduces manufacturing costs and space requirements. Furthermore, the heat dissipation of the capacitor module 20, relay 1300, and fuse 1400 does not need to pass through their respective plastic housings, further shortening the heat dissipation path, reducing thermal resistance, and improving heat dissipation efficiency.

[0085] It should be noted that in this embodiment, the capacitor module 20, relay 1300, and fuse 1400 are all integrated within the receiving cavity 1110. The capacitor module 20, relay 1300, and fuse 1400 are integrated into the receiving cavity 1110 by placing each component within the cavity, and then pouring a sealing material (not shown in the figure) into the cavity. This sealing material effectively encapsulates and fixes the capacitor module 20, relay 1300, and fuse 1400, eliminating the need for separate housings or mounting accessories for each component, thus reducing costs and saving installation space.

[0086] In some embodiments, the housing 1100 is provided with a heat dissipation channel 1120 for the flow of cooling medium to exchange heat with the capacitor module 20, relay 1300, and fuse 1400. At least two of the capacitor module 20, relay 1300, and fuse 1400 share the heat dissipation channel 1120, allowing at least two of them to dissipate heat through the channel alone. This is more cost-effective than having a separate heat dissipation device for each electrical component. In this embodiment, the capacitor module 20, relay 1300, and fuse 1400 all share the heat dissipation channel. Exemplarily, the heat dissipation channel 1120 is arranged around the capacitor module 20, relay 1300, and fuse 1400, so that when the cooling medium flows through the channel 1120, it can remove as much heat as possible from the areas surrounding the capacitor module 20, relay 1300, and fuse 1400, improving heat dissipation efficiency and effect.

[0087] Furthermore, the heat dissipation channel 1120 includes a first flow channel 1121, which is located at the bottom of the capacitor module 20, minimizing the distance between the first flow channel 1121 and the capacitor module 20 and covering as much of the area of ​​the capacitor module 20 as possible. When the cooling medium flows in the first flow channel 1121, it can remove the heat generated at the bottom of the capacitor module 20 in the shortest possible time, which is beneficial to improving the heat dissipation effect and efficiency.

[0088] Furthermore, the heat dissipation channel 1120 also includes a second flow channel 1122, which is located on the side of the housing 1100 and surrounds the capacitor module 20, the relay 1300, and the fuse 1400. This allows the second flow channel 1122 to minimize the distance between itself and the capacitor module 20, the relay 1300, and the fuse 1400, thereby increasing the amount of heat that the cooling medium can carry away when flowing in the second flow channel 1122, thus improving heat dissipation efficiency and effect.

[0089] In some embodiments, the housing 1100 is provided with an inlet 1130 and an outlet 1140. The first flow channel 1121 and the second flow channel 1122 are both connected to the inlet 1130 and the outlet 1140, that is, the first flow channel 1121 and the second flow channel 1122 share a single inlet 1130 and an outlet 1140, which helps to save on component costs and reduce the overall size of the electronic control module 1000. Exemplarily, the housing 1100 is rectangular in this embodiment, with the inlet 1130 located at one corner of the housing 1100 and the outlet 1140 located at the other corner of the housing 1100, and the inlet 1130 and the outlet 1140 are arranged opposite each other along the sides of the rectangle. The second flow channel 1122 can be directly connected from the liquid inlet 1130 to the liquid outlet 1140 along one side of the rectangle, or it can be connected from the liquid inlet 1130 to the liquid outlet 1140 along three sides of the rectangle. In this embodiment, the second flow channel 1122 is connected from the liquid inlet 1130 to the liquid outlet 1140 along the three sides of the rectangle, that is, the second flow channel 1122 forms a U-shape, so that the second flow channel 1122 can cover as much of the circumferential area of ​​the shell 1100 as possible, thereby improving heat dissipation efficiency and heat dissipation effect.

[0090] In some embodiments, as shown in Figures 5 and 6, the receiving cavity 1110 is filled with encapsulation material to encapsulate and fix the capacitor module 20, relay 1300, and fuse 1400. By filling the receiving cavity 1110 with encapsulation material, after the encapsulation material is formed, it can fix the capacitor module 20, relay 1300, and fuse 1400 without the need for separate plastic housings for the capacitor module 20, relay 1300, and fuse 1400 as in conventional technologies. This reduces the obstruction of heat dissipation for the capacitor module 20, relay 1300, and fuse 1400, reduces costs, and saves space in the housing 1100.

[0091] Furthermore, the encapsulation material possesses both thermal conductivity and insulation properties, enabling it to effectively conduct heat when contacting and securing the capacitor module 20, relay 1300, and fuse 1400. This superior heat conduction compared to relying on air improves heat dissipation efficiency. Additionally, the insulation properties of the encapsulation material ensure good insulation between the capacitor module 20, relay 1300, and fuse 1400, preventing current crosstalk and potential electrical hazards among them.

[0092] Furthermore, the encapsulation material can be epoxy resin, polyurethane, silicone gel, etc. Any material with good encapsulation insulation and thermal conductivity can be used as the encapsulation material, without any limitation.

[0093] In some embodiments, please refer to Figures 6 and 7. The capacitor module 20 includes a plurality of driving capacitor cores 1210, and the plurality of driving capacitor cores 1210 are arranged in an array.

[0094] In some embodiments, the capacitor module 20 further includes a plurality of boost capacitor cores 1220, which are disposed along a first direction X on one side of the driving capacitor core 1210 and arranged in a rectangle in conjunction with the driving capacitor cores 1210. The first direction X is the width direction of the housing 1100. Arranging the plurality of boost capacitor cores 1220 and the plurality of driving capacitor cores 1210 in a rectangle saves space in the housing 1100 compared to a random distribution of the boost capacitor cores 1220 and the plurality of driving capacitor cores 1210. Furthermore, arranging the plurality of boost capacitor cores 1220 and the plurality of driving capacitor cores 1210 in one place facilitates the subsequent connection setup between the capacitor module 20 and the relay 1300 and the fuse 1400.

[0095] In some embodiments, referring to Figures 6 and 7, the relay 1300 and the fuse 1400 are arranged along a first direction X, and the relay 1300 and the fuse 1400 are disposed on one side of the capacitor module 20 along a second direction Y. The first direction X is the width direction of the housing 1100, and the second direction Y is the length direction of the housing 1100. By arranging the relay 1300 and the fuse 1400 along the first direction X and disposing them on one side of the capacitor module 20 along the second direction Y, the relay 1300 and the fuse 1400 can utilize the length occupied by the capacitor module 20 in the first direction X, avoiding the relay 1300 and the fuse 1400 occupying additional length in the first direction X. Furthermore, the relay 1300 and the fuse 1400 are arranged side by side in the second direction Y, which helps to save the length occupied by the relay 1300 and the fuse 1400 in the second direction Y. In summary, by arranging the relay 1300, fuse 1400, and capacitor module 20 as described above, the arrangement of the relay 1300, fuse 1400, and capacitor module 20 is more compact, saving space in the housing 1100.

[0096] In some embodiments, please refer to Figures 6, 8 and 9. The housing 1100 is provided with an isolation plate 1150, which is located between the fuse 1400 and the capacitor module 20. The isolation plate 1150 is used to isolate the heat conduction between the capacitor module 20 and the fuse 1400 and reduce the heat damage caused by the fuse 1400 heating up to the capacitor module 20.

[0097] Furthermore, a groove is provided on the inner wall of the housing 1100 near the relay 1300, and a bolt is provided on one side of the relay 1300. The bolt is mainly used to connect with the subsequent connection assembly 1600, and the groove is used to make way for the bolt, thereby improving the space utilization of the housing 1100's receiving cavity 1110.

[0098] In some embodiments, referring to Figures 7, 10 to 12, the electronic control module 1000 includes a connection component 1600. The connection component 1600 is disposed within the receiving cavity 1110 and is used for electrical connection between the relay 1300 and the fuse 1400 and the capacitor module 20, respectively. Further, the connection component 1600 includes a first connector 1610 and a second connector 1620. The first connector 1610 is electrically connected to one electrode side of the capacitor module 20, and the second connector 1620 is electrically connected to the other electrode side of the capacitor module 20. Both the first connector 1610 and the second connector 1620 can be copper busbars. The first connector 1610 can serve as a negative copper busbar, and the second connector 1620 can serve as a positive copper busbar. Correspondingly, the first connector 1610 is connected to the negative electrode side of the capacitor module 20, and the second connector 1620 is connected to the positive electrode side of the capacitor module 20. The first connector 1610 can also serve as a positive copper busbar, and the second connector 1620 as a negative copper busbar. Correspondingly, the first connector 1610 is connected to the positive side of the capacitor module 20, and the second connector 1620 is connected to the negative side of the capacitor module 20. In this embodiment, the first connector 1610 serves as the negative copper busbar and is connected to the negative side of the capacitor module 20, while the second connector 1620 serves as the positive copper busbar and is connected to the positive side of the capacitor module 20.

[0099] In some embodiments, the housing 1100 has a first through slot 1160, a second through slot 1170, a third through slot 1180, and a fourth through slot 1190. A first portion of the connecting assembly 1600 extends to the outside of the housing 1100 through the first through slot 1160, a second portion of the connecting assembly 1600 extends to the outside of the housing 1100 through the second through slot 1170, a third portion of the connecting assembly 1600 extends to the outside of the housing 1100 through the third through slot 1180, and a fourth portion of the connecting assembly 1600 extends to the outside of the housing 1100 through the fourth through slot 1190. By providing multiple through slots on the housing 1100, the parts of the connecting assembly 1600 that need to be externally connected can extend directly to the outside of the housing 1100 through the corresponding through slots, shortening the path of the connecting assembly 1600 to the outside of the housing 1100. This helps to save the length required for the external connection of the connecting assembly 1600 and reduce costs. In subsequent embodiments, the specific components of the connecting assembly 1600 extending to the outside of the housing 1100 through each through slot will be described in detail.

[0100] Furthermore, the first connector 1610 includes a first capacitor connection portion 1611 and a first external output portion 1612. The first capacitor connection portion 1611 is connected to the negative terminal side of the capacitor module 20, and the connection method is to directly weld one side of the capacitor module 20 to the surface of the first capacitor connection portion 1611. The first external output portion 1612 is connected to one side of the first capacitor connection portion 1611, that is, connected to the side of the first capacitor connection portion 1611. Considering the space size of the housing 1100, the first external output portion 1612 and the first capacitor connection portion 1611 are connected at an angle, that is, the first connector 1610 is bent so that the first external output portion 1612 and the first capacitor connection portion 1611 are bent and connected. Preferably, the angle between the first capacitor connection portion 1611 and the first external output portion 1612 is 90° or approximately 90°, so that the first external output portion 1612 does not occupy the space of the housing 1100 on the horizontal plane, which is beneficial to reducing the volume of the electronic control module 1000. The first external output section 1612 extends from the side away from the first capacitor connection section 1611 through the first through slot 1160 to the outside of the receiving cavity 1110 for connecting external devices, such as semiconductor power modules.

[0101] The second connector 1620 includes a second capacitor connection portion 1621 and a second external output portion 1622. The second capacitor connection portion 1621 is connected to the positive terminal side of the capacitor module 20 by directly welding one side of the capacitor module 20 to the surface of the second capacitor connection portion 1621. The second external output portion 1622 is connected to one side of the second capacitor connection portion 1621, i.e., connected to the side of the second capacitor connection portion 1621. Considering the space size of the housing 1100, the second external output portion 1622 and the second capacitor connection portion 1621 are connected at an angle, i.e., the second connector 1620 is bent so that the second external output portion 1622 and the second capacitor connection portion 1621 are bent and connected. Preferably, the angle between the second capacitor connection portion 1621 and the second external output portion 1622 is 90° or approximately 90°, so that the second external output portion 1622 does not occupy the space of the housing 1100 on the horizontal plane, which is beneficial to reducing the volume of the electronic control module 1000. The second external output section 1622 extends from the side away from the second capacitor connection section 1621 through the first through slot 1160 to the outside of the receiving cavity 1110 for connecting external devices, such as semiconductor power modules.

[0102] Furthermore, because the capacitor module 20 has a certain height, the first capacitor connection portion 1611 and the second capacitor connection portion 1621 are respectively connected to both sides of the capacitor module 20, so that the first capacitor connection portion 1611 and the second capacitor connection portion 1621 are arranged opposite to each other. This prevents the two capacitor connection portions from occupying additional horizontal area of ​​the housing 1100, which helps to improve the compactness of the components within the housing 1100. The first external output portion 1612 and the second external output portion 1622 are arranged relatively spaced and parallel to each other, which helps to reduce the stray inductance generated by the first connector 1610 and the second connector 1620.

[0103] In some embodiments, the connecting assembly 1600 further includes an insulating member 1800 with an insulating plate. The first external output portion 1612 and the second external output portion 1622 are both fixed to the insulating member 1800. As an example, the insulating member 1800 is an injection-molded component disposed within the first through groove 1160 and extending to the outside of the bottom of the housing 1100. The first external output portion 1612 of the first connector 1610 and the second external output portion 1622 of the second connector 1620 both extend to the outside of the housing 1100 through the insulating member 1800; in other words, the insulating member 1800 encloses a portion of the first external output portion 1612 and a portion of the second external output portion 1622. The insulating plate in the insulating member 1800 is located between the first external output section 1612 and the second external output section 1622, serving to insulate and isolate the first external output section 1612 and the second external output section 1622, thus preventing excessive stray inductance between them. Furthermore, because the insulating plate 1150 is a metal plate, the first external output section 1612 is also insulated from the insulating plate 1150 by being encased by the insulating member 1800.

[0104] Further, referring to Figure 10, both the first connector 1610 and the second connector 1620 have fixing holes 1630. The multiple fixing holes 1630 are mainly used to help the encapsulating material fill the gaps between the components as much as possible when it is encapsulated within the housing 1100. As an example, fixing holes 1630 are provided on the first capacitor connection 1611, the second capacitor connection 1621, and the first external output 1612, allowing the encapsulating material to fill the gaps between the first capacitor connection 1611 and the housing 1100, and between the first capacitor connection 1611 and the capacitor module 20, thus ensuring sufficient insulation between the capacitor module 20 and the housing 1100. Similarly, the encapsulating material can also fill the gaps between the second capacitor connection 1621 and the housing 1100, and between the second capacitor connection 1621 and the capacitor module 20, through the fixing holes 1630, ensuring sufficient insulation between the capacitor module 20 and the housing 1100. The encapsulation material can also fill the gap between the first external output section 1612 and the housing 1100, and the gap between the first external output section 1612 and the capacitor module 20 through the fixing hole 1630, so that the capacitor module 20 and the housing 1100 are fully insulated.

[0105] Furthermore, referring to Figure 11, the end of the first external output section 1612 away from the first capacitor connection section 1611 is bent to form a first overlapping surface 1613, which facilitates a scanning overlap between the first external output section 1612 and external devices, such as the terminals of a power module. Similarly, the end of the second external output section 1622 away from the second capacitor connection section 1621 is bent to form a second overlapping surface 1623, which facilitates a scanning overlap between the second external output section 1622 and external devices, such as the terminals of a power module.

[0106] In some embodiments, referring to FIG7, the connection assembly 1600 further includes a third connector 1680, which is connected to the boost capacitor core 1220 and flush with the second capacitor connection portion 1621 of the second connector 1620. The second connector 1620 is only used to connect the drive capacitor core 1210, and the third connector 1680 is only used to connect the boost capacitor core 1220, thus avoiding interference between the drive capacitor core 1210 and the boost capacitor core 1220.

[0107] In some embodiments, referring to Figures 7 and 12, the connection assembly 1600 further includes a first connection terminal 1640 and a second connection terminal 1650. A portion of the first connection terminal 1640 is electrically connected to the relay 1300, and a portion extends out of the housing 1100 through the second through-slot 1170 for electrical connection to external devices. By utilizing the first connection terminal 1640, the relay 1300 can be integrated into the housing 1100 while still being electrically connected to external devices. A portion of the second connection terminal 1650 is electrically connected to the capacitor module 20, a portion is electrically connected to the relay 1300, and a portion extends out of the housing 1100 through the second through-slot 1170, enabling the relay 1300 to be integrated into the housing 1100 while also allowing the relay 1300 to be electrically connected to the capacitor module 20 and external devices.

[0108] Further, referring to Figure 12, the first connection terminal 1640 includes a first external portion 1641, a second external portion 1642, a first extension portion 1643, and a first fixing portion 1644. The first fixing portion 1644 and the first external portion 1641 are respectively bent and disposed at both ends of the first extension portion 1643 along the second direction Y. The first fixing portion 1644 is located on one side of the capacitor module 20 in the first direction X. A portion of the first external portion 1641 is exposed to the outside of the housing 1100 through the fourth through slot 1190. The first fixing portion 1644, the first external portion 1641, and the first extension portion 1643 are essentially arranged around the capacitor module 20 and the relay 1300, forming an overall U-shape. This arrangement not only enables electrical connection between the capacitor module 20, the relay 1300, and external devices, but also minimizes the area occupied by the first connection terminal 1640 in the receiving cavity 1110. The first fixing part 1644 is fixedly connected to the relay 1300. Specifically, the high-voltage terminal on the relay 1300 passes through the first fixing part 1644 and is fastened by bolts. The bolts are located in the grooves on the inner wall of the housing 1100, improving the space utilization of the housing 1100 and avoiding the bolts. The second external part 1642 is connected to the first fixing part 1644 and at least part of it protrudes outside the housing 1100 for electrical connection with external devices.

[0109] The second connection terminal 1650 includes a first inner connection portion 1651, a second fixing portion 1652, and a third outer connection portion 1653. The first inner connection portion 1651 and the second fixing portion 1652 are respectively bent and connected to the two ends of the third outer connection portion 1653 in the second direction Y, so that the second connection terminal 1650 is U-shaped. The relay 1300 is located between the first inner connection portion 1651 and the third outer connection portion 1653, making full use of the space formed by the second connection terminal 1650, avoiding space waste, and improving the structural compactness between components. The first inner connection portion 1651 is electrically connected to the capacitor module 20, specifically by overlapping the third connector 1680, and then electrically connected to the boost capacitor core 1220 in the capacitor module 20 through the third connector 1680. The third outer connection portion 1653 is exposed outside the housing 1100 through the second through slot 1170 for electrical connection with external devices.

[0110] It should be noted that there can be multiple second connection terminals 1650, arranged along the first direction X. The number of second connection terminals 1650 mainly depends on the number of high-voltage terminals of the relay 1300, with two high-voltage terminals corresponding to one second connection terminal 1650.

[0111] In some embodiments, the relay 1300 is disposed within an insulating box 1700, which is located within a receiving cavity 1110. The insulating box 1700 provides insulation between the relay 1300 and the capacitor module 20 and the housing 1100. Furthermore, the insulating box 1700 has an opening on the side facing the bottom of the housing 1100, facilitating the placement of the relay 1300 within the insulating box and improving the heat dissipation of the relay 1300.

[0112] In some embodiments, the connection assembly 1600 further includes a third connection terminal 1660 and a fourth connection terminal 1670. The third connection terminal 1660 is fixed to one side of the insulating member 1800 and protrudes outside the housing 1100 through the third through groove 1180. The portion of the third connection terminal 1660 located inside the housing 1100 is electrically connected to one end of the fuse 1400 by bolts, and the other end of the fuse 1400 is electrically connected to the fourth connection terminal 1670. The fourth connection terminal 1670 is fixedly connected to the first external output portion 1612 of the first connector 1610.

[0113] Based on the structure of the electronic control module 1000 described in the above embodiments, a comparison is made below between the heat dissipation paths of the components in the traditional electronic control module 1000 and the heat dissipation paths of the components in the electronic control module 1000 of this application:

[0114] The traditional heat dissipation path of the 1000 electronic control module:

[0115] The heat dissipation path of capacitor module 20 is as follows: internal core, epoxy resin, plastic shell, heat dissipation base plate, air, electrical control box, and outside air.

[0116] The heat dissipation path of relay 1300 is: internal core, air, plastic casing, air, electrical control box, external air connection. The heat dissipation path of fuse 1400 is the same as that of relay 1300, and will not be described again.

[0117] The heat dissipation path of the electronic control module 1000 in this application is as follows:

[0118] The heat dissipation path of capacitor module 20 is: capacitor core, epoxy resin, housing 1100, and outside air.

[0119] The heat dissipation path for relay 1300 and fuse 1400 is: internal core, housing 1100, and outside air.

[0120] As can be seen, compared to the traditional electronic control module 1000, the heat dissipation path of this application does not need to pass through the plastic shell, heat sink, and internal air. In other words, in terms of heat dissipation, the thermal resistance of this application is reduced by minimizing the thermal resistance of the plastic shell, heat sink, and internal air. Furthermore, since the thermal resistance of air and other components is much greater than that of metal, the total thermal resistance of the electronic control module 1000 provided by this application is significantly reduced from the inside out. It should be noted that thermal resistance refers to the degree to which heat transfer is impeded, just as resistance impedes the transfer of current. The greater the thermal resistance, the greater the resistance to heat conduction. Higher thermal resistance means more severe heat generation in the device (because heat transfer to the outside is greatly hindered), and the device's lifespan will be reduced at high temperatures. Excessive thermal resistance in the capacitor module will cause the device to overheat when operating at high current, further leading to a decrease in the device's insulation capacity or even breakdown damage.

[0121] According to a third aspect of this application, this application also provides a controller. Referring to FIG13, the controller includes a housing and an electronic control module 1000 as described in any of the foregoing embodiments. The housing 10 is provided with a receiving portion 11, and the electronic control module 1000 is disposed within the receiving portion 11. Since this controller has all the structure and beneficial effects of the aforementioned electronic control module 1000, this embodiment will not be described in detail here.

[0122] It should be noted that, for the structure of the controller, it is also possible to directly integrate all the components in the electronic control module 1000, such as the capacitor module 20, relay 1300, fuse 1400, and connection component 1600, into the housing 10, eliminating the use of the shell 1100. The housing 11 inside the housing 10 is directly filled with encapsulation material to complete the encapsulation of the electronic control module 1000 without the shell 1100. Compared with the dual structure of using the shell 1100 and the housing 10, it is more conducive to reducing costs and improving heat dissipation.

[0123] In some embodiments, the controller 100 is suitable for motor controllers 100, photovoltaic controllers 100, energy storage controllers 100, etc. The controller 100 includes the capacitor module 20a described above.

[0124] Referring to Figures 14 to 32, in some embodiments, the controller 100 includes a capacitor module 20 and a power module 30, wherein at least one of the capacitor module 20 and the power module 30 is the capacitor module 20a described above.

[0125] Referring to Figures 26 and 27, in some embodiments, the capacitor module 20 includes a capacitor core assembly 23, a first busbar 21, and a second busbar 22. It can be understood that the first busbar 21 is a first connector 1610, and the second busbar 22 is a second connector 1620. The capacitor core assembly 23 includes multiple cores arranged along the thickness direction of the cores (Y direction in the figures); specifically, the cores are a driving capacitor core 1210 and a boost capacitor core 1220. The first busbar 21 is disposed above the capacitor core assembly 23, and the second busbar 22 is disposed below the capacitor core assembly 23.

[0126] The first busbar 21 and the second busbar 22 have opposite polarities. In some embodiments, the first busbar 21 can be a negative busbar and the second busbar 22 can be a positive busbar.

[0127] Specifically, the first busbar 21 has a negative power input terminal 212 and a negative power output terminal, and the second busbar 22 has a positive power input terminal 222 and a positive power output terminal. The negative power output terminal and the positive power output terminal are located on one side of the width direction (X direction in the figure) of the capacitor core assembly 23, and the negative power input terminal 212 and the positive power input terminal 222 are located on the other side of the width direction of the capacitor core assembly 23.

[0128] In some embodiments, the negative input terminal 212 and the positive input terminal 222 of the power supply are located on the side of the capacitor core assembly 23. Both the positive and negative input terminals and the positive and negative output terminals of the power supply can be horizontally positioned.

[0129] In some embodiments, referring to FIG28, the power module 30 includes a three-phase output terminal 33. Correspondingly, the capacitor module 20 has three sets of input terminals, each set of input terminals including a first input terminal 31 and a second input terminal 32 with opposite polarities.

[0130] In some embodiments, the capacitor module 20 includes a first output terminal 211 and a second output terminal 221, the first output terminal 211 and the second output terminal 221 having opposite polarities, and the first output terminal 211 and the second output terminal 221 are spaced apart. The power module 30 includes a first input terminal 31 and a second input terminal 32, the first input terminal 31 and the second input terminal 32 having opposite polarities, the first input terminal 31 being electrically coupled to the first output terminal 211, and the second input terminal 32 being electrically coupled to the second output terminal 221, and the first input terminal 31 and the second input terminal 32 being spaced apart.

[0131] Specifically, in the projection plane perpendicular to the thickness direction (Z direction in the figure) of the first output terminal 211, the projection of the first output terminal 211 falls into the projection of the second output terminal 221, and the projection of the first input terminal 31 falls into the projection plane of the second input terminal 32.

[0132] In some embodiments, the first output terminal 211 and the second output terminal 221 may be parallel, and the first input terminal 31 and the second input terminal 32 may be parallel.

[0133] For example, the first output terminal 211 and the second output terminal 221 are spaced apart along their thickness direction, and the first output terminal 211 and the second output terminal 221 are parallel to each other. The first output terminal 211 may be disposed above the second output terminal 221. The first input terminal 31 and the second input terminal 32 are spaced apart along their thickness direction, and the first input terminal 31 and the second input terminal 32 are parallel to each other. The first input terminal 31 may be disposed above the second input terminal 32.

[0134] In some embodiments, the first output terminal 211 is the negative output terminal of the first busbar 21, the second output terminal 221 is the positive output terminal of the second busbar 22, the first input terminal 31 is the negative input terminal corresponding to the first output terminal 211, and the second input terminal 32 is the positive input terminal corresponding to the second output terminal 221.

[0135] A first output terminal 211 and a first input terminal 31 are electrically coupled to form a first current path, and a second output terminal 221 and a second input terminal 32 are electrically coupled to form a second current path. Since the first output terminal 211 and the second output terminal 221 have opposite polarities, the first current path and the second current path are opposite, and the direction of the magnetic field around the first current path is opposite to the direction of the magnetic field around the second current path.

[0136] In this embodiment, by arranging the relative positions of the first output terminal 211 and the second output terminal 221, and the relative positions of the first input terminal 31 and the second input terminal 32, such that in a projection plane perpendicular to the thickness direction of the first output terminal 211, the projection of the first input terminal 31 falls within the projection of the second input terminal 32, and the projection of the first output terminal 211 falls within the projection of the second output terminal 221, compared to arranging them side by side along the length of the connecting terminal, the centers of the first output terminal 211 and the second output terminal 221, and the centers of the first input terminal 31 and the second input terminal 32 are closer together. As a result, the first current path and the second current path are closer together, so that the overlapping portions of the magnetic fields around the first current path and the magnetic fields around the second current path cancel each other out due to the opposite directions of the magnetic fields during the energizing process. This helps to reduce stray inductance and improve the stability of the controller 100 operation.

[0137] In some embodiments, referring to FIG22, the controller 100 further includes a first insulating member 40, which is at least partially disposed between the first output terminal 211 and the second output terminal 221 to insulate the first output terminal 211 from the second output terminal 221, which helps to improve the insulation reliability between the first output terminal 211 and the second output terminal 221.

[0138] In some embodiments, referring to FIG22, the controller 100 further includes a second insulator 50, which is at least partially disposed between the first input terminal 31 and the second input terminal 32 to insulate the first input terminal 31 from the second input terminal 32, thereby helping to improve the insulation reliability between the first input terminal 31 and the second input terminal 32.

[0139] Referring to Figures 21 to 25, in some embodiments, the controller 100 further includes a first electrical connector 60, one end of which is connected to a first output terminal 211 and the other end of which is connected to a first input terminal 31. It can be understood that the first output terminal 211 and the first input terminal 31 are electrically coupled through the first electrical connector 60.

[0140] Referring to Figures 21 to 25, in some embodiments, the controller 100 further includes a second electrical connector 70, one end of which is connected to the second output terminal 221, and the other end is connected to the second input terminal 32. The second output terminal 221 and the second input terminal 32 are electrically coupled through the second electrical connector 70.

[0141] It can be understood that the first electrical connector 60 and the second electrical connector 70 are conductive components. The first electrical connector 60 is a bridge connecting the first output terminal 211 and the first input terminal 31, and the second electrical connector 70 is a bridge connecting the second output terminal 221 and the second input terminal 32.

[0142] Typically, the two output terminals of capacitor module 20 and the two input terminals of power module 30 are connected by nuts, with the output terminals stacked on top of the input terminals. This connection method requires power module 30 to be assembled into controller 100 first, followed by capacitor module 20. If capacitor module 20 is integrated with other components of controller 100, assembling power module 30 first will make it difficult to assemble with it. Conversely, if power module 30 is assembled into controller 100 first, and then controller 100 is integrated with other components, power module 30 may be damaged during transportation and handling during the integrated manufacturing process, leading to a decrease in its performance.

[0143] In this embodiment, by providing a first electrical connector 60 and a second electrical connector 70, the two output terminals of the capacitor module 20 and the two input terminals of the power module 30 are not in direct contact. As a result, the assembly order of the capacitor module 20 and the power module 30 is not limited by the other, and they can be assembled independently, which helps to improve the assembly flexibility of the power module 30 and the capacitor module 20.

[0144] In some embodiments, referring to Figures 22 and 25, the controller 100 further includes a third insulating member 76 disposed between the first electrical connector 60 and the second electrical connector 70 to insulate the first connector from the second electrical connector 70.

[0145] In this embodiment of the application, by providing a third insulating member 76, not only is the risk of short circuit between the first electrical connector 60 and the second electrical connector 70 reduced, but the first electrical connector 60 and the second electrical connector 70 can also be brought closer together. As a result, the first current path and the second circuit path are brought closer together, which helps the magnetic fields around the first current path and the magnetic fields around the second current path to cancel each other out to a large extent.

[0146] To further improve insulation reliability, in some embodiments, an insulating layer may be provided on the side of the first electrical connector 60 facing the second electrical connector 70, and an insulating layer may be provided on the side of the second electrical connector 70 facing the first electrical connector 60.

[0147] In some embodiments, the first electrical connector 60 may also be wrapped with an insulating material, wherein the insulating material covers the surface of the first electrical connector 60 other than the contact areas with the first output terminal 211 and the first input terminal 31. The second electrical connector 70 may also be wrapped with an insulating material, wherein the insulating material covers the surface of the second electrical connector 70 other than the contact areas with the second output terminal 221 and the second input terminal 32.

[0148] In some embodiments, the first electrical connector 60 is soldered to the first output terminal 211 and / or the first input terminal 31.

[0149] In some embodiments, the second electrical connector 70 is welded to the second output terminal 221 and / or the second input terminal 32.

[0150] In other embodiments, the welding described above can be replaced by riveting, crimping, etc.

[0151] Typically, the output terminal of capacitor module 20 is connected to the input terminal of power module 30 via a nut. In this connection method, the nut is prone to loosening, leading to poor contact, which in turn causes problems such as arcing and breakage, and also increases stray inductance.

[0152] In this embodiment, by welding the first electrical connector 60 to the first output terminal 211 and the first input terminal 31, and welding the second electrical connector 70 to the second input terminal 32 and the second output terminal 221, the first electrical connector 60 is stably connected to the first output terminal 211 and the first input terminal 31, and the second electrical connector 70 is stably connected to the second input terminal 32 and the second output terminal 221. This helps to alleviate the problems of arcing, breakage and increased stray inductance caused by nut connection, thereby improving the operational stability of the controller 100.

[0153] In some embodiments, a first output terminal 211 is disposed above a second output terminal 221. The width of the second output terminal 221 is greater than the width of the first output terminal 211. Along the width direction of the second output terminal 221 (X direction in the figure), the free end of the second output terminal 221 extends beyond the free end of the first output terminal 211, so that the first output terminal 211 and the second output terminal 221 are staggered in a stepped manner. A first input terminal 31 is disposed above a second input terminal 32. The width of the second input terminal 32 is greater than the width of the first input terminal 31. Along the width direction of the second input terminal 32, the free end of the second input terminal 32 extends beyond the free end of the first input terminal 31, so that the first input terminal 31 and the second input terminal 32 are staggered in a stepped manner. The first output terminal 211 and the first input terminal 31 are respectively welded to a first electrical connector 60. The second output terminal 221 and the second input terminal 32 are respectively welded to a second electrical connector 70.

[0154] In this embodiment, by extending the free end of the second output terminal 221 beyond the free end of the first output terminal 211, and extending the free end of the second input terminal 32 beyond the free end of the first input terminal 31, the upper first output terminal 211 does not completely block the lower second output terminal 221, and the upper first input terminal 31 does not completely block the lower second input terminal 32, so that the second connector can be welded to the second output terminal 221 and the second input terminal 32. This helps to reduce the assembly difficulty of the power module 30 and the capacitor module 20.

[0155] For example, the portion of the second output terminal 221 extending beyond the free end of the first output terminal 211 is used as the welding area for welding with the second electrical connector 70, and the portion of the second input terminal 32 extending beyond the free end of the first output terminal 211 is also used as the welding area for welding with the second electrical connector 70. By scanning with a laser from top to bottom, the first output terminal 211 and the first input terminal 31 do not obstruct the welding area below, which helps reduce the difficulty of welding the second electrical connector 70 to the second output terminal 221 and the second input terminal 32.

[0156] In some embodiments, referring to Figures 29 and 31, the first electrical connector 60 is provided with a first stress relief portion 64. Providing the first stress relief portion 64 helps to release the deformation stress generated by the pressure or heat on the first electrical connector 60 during laser welding, reduces the welding gap between the first electrical connector 60 and the first output terminal 211 and the first input terminal 31, and improves welding stability.

[0157] In some embodiments, the second electrical connector 70 is provided with a second stress relief portion 73. Providing the second stress relief portion 73 helps to release the deformation stress generated by the pressure or heat on the second electrical connector 70 during laser welding, reduces the welding gap between the second electrical connector 70 and the second output terminal 221 and the second input terminal 32, and improves welding stability.

[0158] The structures of the first stress relief part 64 and the second stress relief part 73 may be the same or different.

[0159] The first stress relief part 64 and the second stress relief part 73 can be constructed as a through hole 761, a notch, or other structures.

[0160] For example, as shown in Figures 29 and 31, the first stress relief part 64 is a rectangular groove provided on the edge of the first electrical connector 60, and the second stress relief part 73 is a rectangular groove provided on the edge of the second electrical connector 70.

[0161] In some embodiments, the length of the first output terminal 211 is the same as the length of the second output terminal 221. The length of the first input terminal 31 is the same as the length of the second input terminal 32.

[0162] In some embodiments, the width of the first output terminal 211 is smaller than the width of the second output terminal 221, and the free end of the second output terminal extends beyond the free end of the first output terminal. The width of the first input terminal 31 is smaller than the width of the second input terminal 32, and the free end of the second input terminal extends beyond the free end of the first input terminal.

[0163] In some embodiments, referring to FIG26, the first insulating member 40 includes a first insulating portion 41 and a second insulating portion 42. The first insulating portion 41 is disposed between the first output terminal 211 and the second output terminal 221, and the second insulating portion 42 protrudes from the side of the first insulating portion 41 facing the first output terminal 211 and is located on the side of the first output terminal 211 near the first input terminal 31.

[0164] For example, as shown in FIG26, the first insulating part 41 is horizontally arranged, and the second insulating part 42 is vertically arranged along the thickness direction of the first insulating member 40. The second insulating part 42 is located outside the first output terminal 211.

[0165] In this embodiment of the application, by providing a second insulating part 42, the creepage distance between the first output terminal 211 and the second output terminal 221 is increased, which helps to reduce the safety hazards caused by arcing of the first output terminal 211 and the second output terminal 221 under high voltage.

[0166] In some embodiments, the second insulating portion 42 protrudes from the side of the first output terminal 211 away from the second output terminal 221, which further increases the creepage distance between the first output terminal 211 and the second output terminal 221.

[0167] It is understood that in this embodiment, the top surface of the second insulating portion 42 is higher than the top surface of the first output terminal 211.

[0168] In some embodiments, the first insulating member 40 is provided with a first positioning portion 43, which is configured to position the first electrical connector 60. This configuration reduces the risk of displacement of the first electrical connector 60 during connection with the first output terminal 211 and the first input terminal 31, thereby improving connection stability.

[0169] In some embodiments, referring to Figures 21, 26 and 29, the first positioning part 43 is a protrusion protruding from the first insulating member 40, and a first positioning groove 66 is provided at one end of the first electrical connector 60 near the capacitor module 20, and the first positioning part 43 is configured to be confined within the first positioning groove 66.

[0170] Referring to FIG26, in some embodiments, the first positioning part 43 may also be configured to position the first output end 211.

[0171] In some embodiments, the first insulating member 40 is provided with a second positioning portion 44, which is configured to position the second electrical connector 70. This configuration reduces the risk of displacement of the second electrical connector 70 during connection with the second output terminal 221 and the second input terminal 32, thereby improving connection stability.

[0172] Referring to FIG26, in some embodiments, the second positioning part 44 may also be configured to position the second output end 221.

[0174] In some embodiments, referring to FIG28, the second insulating member 50 includes a third insulating portion 51 and a fourth insulating portion 52. The third insulating portion 51 is disposed between the first input terminal 31 and the second input terminal 32, and the fourth insulating portion 52 protrudes from the side of the third insulating portion 51 facing the first input terminal 31 and is located on the side of the first input terminal 31 near the first output terminal 211.

[0175] For example, as shown in FIG28, along the width direction of the second insulating member 50, the end of the third insulating part 51 extends out of the end of the fourth insulating part 52, the fourth insulating part 52 carries the first input terminal 31 and the second input terminal 32, and the fourth insulating part 52 surrounds the outer periphery of the first input terminal 31.

[0176] In this embodiment of the application, by providing a fourth insulating part 52, the creepage distance between the first input terminal 31 and the second input terminal 32 is increased, which helps to reduce the safety hazards caused by arcing between the first input terminal 31 and the second input terminal 32 under high voltage.

[0177] In some embodiments, the fourth insulating portion 52 protrudes from the side of the first input terminal 31 away from the second input terminal 32, which further increases the creepage distance between the first input terminal 31 and the second input terminal 32.

[0178] In some embodiments, referring to FIG28, the second insulating member 50 is provided with a third positioning part 53, which is configured to position the first electrical connector 60 so as to reduce the risk of displacement of the first electrical connector 60 during connection with the first output terminal 211 and the first input terminal 31, thereby helping to improve connection stability.

[0179] In some embodiments, the third positioning part 53 is also configured to position the second electrical connector 70 so as to reduce the risk of displacement of the second electrical connector 70 during connection with the second output terminal 221 and the second input terminal 32, thereby helping to improve connection stability.

[0180] In some embodiments, the third positioning part 53 is further configured to position the third insulating member 76 to improve the insulation reliability between the first electrical connector 60 and the second electrical connector 70.

[0181] In some embodiments, the third positioning portion 53 is a protrusion extending from the second insulating member 50, the first electrical connector 60 is provided with a third positioning groove 67, and the third positioning portion 53 is configured to be confined within the third positioning groove 67.

[0182] In some embodiments, the second electrical connector 70 is provided with a fourth positioning groove 75, and the third positioning part 53 is further configured to be confined within the fourth positioning groove 75.

[0183] In some embodiments, the third insulating member 76 is further provided with a fifth positioning groove 762, and the third positioning part 53 is further configured to be confined within the fifth positioning groove 762.

[0184] It is understandable that the third positioning groove 67, the fourth positioning groove 75 and the fifth positioning groove 762 correspond to each other, and the third positioning part 53 simultaneously positions the first electrical connector 60, the second electrical connector 70 and the third insulating member 76.

[0185] In some embodiments, referring to Figures 23 and 28, the second insulating member 50 is provided with a fourth positioning part 54, which is configured to position the first electrical connector 60 so as to reduce the risk of displacement of the first electrical connector 60 during connection with the second output terminal 221 and the second input terminal 32, thereby helping to improve connection stability.

[0189] Referring to FIG29, in some embodiments, the first electrical connector 60 includes a first overlapping portion 61, a second overlapping portion 62, and a connecting portion 63. The first overlapping portion 61 and the second overlapping portion 62 are respectively connected to the two ends of the connecting portion 63. The first overlapping portion 61, the second overlapping portion 62, and the connecting portion 63 are parallel. The first overlapping portion 61 and the second overlapping portion 62 are coplanar. The connecting portion 63 is higher than the first overlapping portion 61 and the second overlapping portion 62 to avoid the second insulating portion 42 and the fourth insulating portion 52. The first overlapping portion 61 is connected to the first output terminal 211, and the second overlapping portion 62 is connected to the first input terminal 31.

[0190] Referring to FIG31, in some embodiments, the second electrical connector 70 includes a third overlap portion 71 and a fourth overlap portion 72 connected to each other, the third overlap portion 71 being connected to the second output terminal 221 and the fourth overlap portion 72 being connected to the second input terminal 32.

[0191] In some embodiments, the second electrical connector 70 is provided with two rows of identification portions, which are spaced apart along the width direction (X direction in the figure) of the second electrical connector 70. Each row of identification portions includes a plurality of identification holes 65 spaced apart along the length direction (Y direction in the figure) of the second electrical connector 70. Along the thickness direction of the second electrical connector 70, the projection of the identification hole 65 does not overlap with the second output terminal 221, and the projection of the identification hole 65 does not overlap with the second input terminal 32.

[0192] It is understood that the area between the two rows of identification parts is the non-welded area, and the area outside the two rows of identification parts is the welded area. When the second electrical connector 70 is welded to the second output terminal 221 and the second input terminal 32 respectively, the laser scanning area can be controlled by observing the position of the identification parts, thus avoiding the risk of perforation of the second electrical connector due to welding to the non-welded area.

[0193] In some embodiments, the first electrical connector 60 and the second electrical connector 70 may be formed by stamping sheet metal parts.

[0194] Referring to Figures 14 to 20, in some embodiments, the controller 100 further includes a housing 10 with a receiving portion 11, in which the power module 30 and the capacitor module 20 are disposed. By providing the housing 10 to protect the power module 30 and the capacitor module 20, the service life of the controller 100 is extended.

[0195] In some embodiments, the housing 10 is provided with a flow channel containing a cooling medium, which is used to cool the power module 30 and the capacitor module 20.

[0197] In this embodiment, by providing a flow channel in the housing 10 to accommodate the cooling medium, the housing 10 functions as a heat dissipation device. As a result, there is no need to separately provide heat exchange components, which helps to simplify the number of components and reduce the size of the controller 100.

[0200] The thermally conductive material 80 may include, but is not limited to, silicone gel, paraffin, thermally conductive adhesive, etc.

[0201] In this embodiment, by providing a thermally conductive material 80, the heat exchange efficiency between the capacitor module 20 and the cooling medium is improved, which helps to improve the cooling effect on the capacitor module 20.

[0202] In some embodiments, thermally conductive material 80 is filled into the first sub-receiving portion 111, which helps to integrate the capacitor module 20 with the housing 10 and improves the integration of the controller 100.

[0203] In some embodiments, the assembled structure of the capacitor core assembly 23, the first busbar 21, and the second busbar 22 is embedded in the thermally conductive material 80. It can be understood that the capacitor module 20 eliminates the need for a casing, and the molded thermally conductive material 80 improves heat exchange efficiency while also providing the protection of a casing.

[0204] In some embodiments, referring to Figures 18, 19, 20, 32, and 33, the controller 100 may further include a separator and a baffle 12. The separator is integrally formed with the housing 10. A first sub-receiving portion 111 and a second sub-receiving portion 112 are located on opposite sides of the separator. The separator is provided with a clearance groove 131, the opening of which extends to the top of the separator. The clearance groove 131 facilitates the assembly of the capacitor module 20 into the first sub-receiving portion 111, and the extension of the first output terminal 211 and the second output terminal 221 into the second sub-receiving portion 112.

[0205] The baffle 12 is located on the side of the separator facing the first sub-receiving portion 111, and the baffle 12 is provided with a slot corresponding to the clearance groove 131. A gap is formed between the clearance groove 131 and the slot for the first output end 211 and the second output end 221 to pass through.

[0206] During the specific assembly, the capacitor module 20 can be assembled into the first sub-accommodating part 111 first, then the baffle 12 can be snapped onto the separator, and finally epoxy resin can be poured into the first sub-accommodating part 111.
