[0002] This disclosure claims priority to Chinese Patent Application No. 202510072850.0, filed on January 16, 2025, entitled "Electrical Component Module, Motor Controller and Vehicle", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of electrical device technology, specifically to an electrical device module, a motor controller, and a vehicle. Background Technology

[0005] In related technologies, capacitors and power modules are independent modules, typically arranged separately in the motor controller housing and electrically connected via connectors. The components consisting of capacitors and power modules occupy a significant amount of space within the motor controller housing, resulting in lower power density. Furthermore, these components exhibit high stray inductance, leading to substantial circuit losses and signal attenuation. Summary of the Invention

[0050] Furthermore, the integrated design of the first capacitor core and power module results in a more compact structure, smaller overall size, less space occupation, and higher volumetric and power densities.

On the other hand, when the electrical component module is used in the motor controller, it also improves the volumetric and power densities of the motor controller.

[0077] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0078] In this disclosure, it should be understood that directional terms such as "upper" and "lower" are defined according to the orientation of the accompanying drawings and are used only for the convenience of describing this disclosure and simplifying the description. They are not intended to indicate or imply that the device or element referred to must have a specific orientation, or a specific orientation structure and operation, and therefore should not be construed as a limitation of this disclosure. Directional terms such as "first direction," "second direction," and "third direction" can be referred to in Figures 1, 8, 10 to 12, 14 to 15, and 17.

[0079] The terms "inner" and "outer" refer to the inner and outer contours of the corresponding structures. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element.

[0080] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0081] As shown in Figures 1 to 21, according to a first aspect of this disclosure, an electrical device module 1000 is provided, including a housing 1, a first capacitor core 2, and a power module 3. The first capacitor core 2 and the power module 3 are both mounted on the housing 1, and the first capacitor core 2 is electrically connected to the power module 3 so that the first capacitor core 2 and the power module 3 can cooperate with each other to achieve filtering and conversion of the circuit.

[0082] Through the above technical solution, since the first capacitor core 2 and the power module 3 are both installed in the same housing 1, that is, the first capacitor core 2 and the power module 3 are integrated in the same housing 1, the integrated design of the first capacitor core 2 and the power module 3 is realized. The integrated design of the first capacitor core 2 and the power module 3 allows the distance between the first capacitor core 2 and the power module 3 to be shortened, which is beneficial to shortening the connection path between the first capacitor core 2 and the power module 3, thereby shortening the loop length between the first capacitor core 2 and the power module 3 and reducing the stray inductance between the first capacitor core 2 and the power module 3.

[0083] Furthermore, the integrated design of the first capacitor core 2 and the power module 3 results in a more compact structure, smaller overall size, less space occupation, and higher volumetric and power densities. On the one hand, this facilitates the placement of the electrical component module 1000 within the motor controller, reducing the overall size of the motor controller and making it easier to install in equipment (such as vehicles). On the other hand, when the electrical component module 1000 is used in the motor controller, it also improves the volumetric and power densities of the motor controller.

[0084] It should be noted that the aforementioned electrical component module 1000 can be applied to any suitable device, such as a motor controller. Furthermore, this disclosure does not limit the specific type of the aforementioned housing 1. The housing 1 can be a housing 1 for mounting the first capacitor core 2 and the power module 3; that is, the first capacitor core 2 and the power module 3 are mounted on the housing 1 and installed together with the housing 1 within the motor controller's housing. Alternatively, the housing 1 can also be the motor controller's housing, with the first capacitor core 2 and the power module 3 directly integrated into the motor controller's housing; this disclosure does not limit its application in this regard.

[0085] Optionally, the electrical component module 1000 further includes a first connection component 4 and a second connection component 5. One of the first connection component 4 and the second connection component 5 is connected between the positive terminal of the first capacitor core 2 and the first power module input terminal 301 of the power module 3, and the other of the first connection component 4 and the second connection component 5 is connected between the negative terminal of the first capacitor core 2 and the second power module input terminal 302 of the power module 3. The first connection component 4 and the second connection component 5 enable electrical connection between the first capacitor core 2 and the power module 3.

[0086] In this disclosure, the first capacitor core 2 and the power module 3 can also be installed at any position of the housing 1. For example, the first capacitor core 2 and the power module 3 can both be installed inside or outside the housing 1, or one of the first capacitor core 2 and the power module 3 can be installed inside the housing 1, and the other of the first capacitor core 2 and the power module 3 can be installed outside the housing 1. This disclosure does not limit this.

[0087] For example, as shown in Figures 1 and 3, in one exemplary embodiment of this disclosure, the first capacitor core 2 is located inside the housing 1, and the power module 3 is located outside the housing 1. Since the power module 3 is located outside the housing 1, there is a large operating space around the power module 3, which facilitates the electrical connection between the power module 3 and the first capacitor core 2.

[0088] Optionally, a first opening 101 is formed on the housing 1, through which the first connecting component 4 and the second connecting component 5 pass. Thus, during the assembly of the electrical component module 1000, the first capacitor core 2 can be connected to the first connecting component 4 and the second connecting component 5 firstly, then the first capacitor core 2 can be placed inside the housing 1, with the first connecting component 4 and the second connecting component 5 passing through the first opening 101, and then the power module 3 can be connected to the first connecting component 4 and the second connecting component 5, thereby achieving the connection between the first capacitor core 2 and the power module 3. Since the power module 3 is located outside the housing 1, there is ample operating space around it, facilitating the connection between the first connecting component 4 and the second connecting component 5 and the power module 3. In other words, the power module 3, located outside the housing 1, can be easily connected to the first connecting component 4 and the second connecting component 5, thereby reducing the assembly difficulty of the electrical component module 1000 and improving the overall assembly efficiency of the electrical component module 1000.

[0089] Furthermore, the power module 3, located outside the housing 1, can be easily connected to an external load (such as a motor). As shown in Figures 1 and 5 to 7, the power module 3 is provided with an output pin 303, which is located outside the housing 1, facilitating connection of the output pin 303 to an external load.

[0090] To facilitate control of the power module 3, optionally, as shown in Figure 6, the power module 3 is also provided with a control pin 304. Through the control pin 304, electrical connection and signal transmission between the controller and the power module 3 can be achieved, thereby enabling control of the power module 3 and changing its output power and voltage. Since the power module 3 is located outside the housing 1, and the control pin 304 is also located outside the housing 1, it facilitates electrical connection between the control pin 304 and the controller.

[0091] Optionally, as shown in Figures 1, 3, and 7, the power module 3 and the first capacitor core 2 can be spaced apart along the thickness direction of the housing 1 (the first direction mentioned below). This spaced-apart arrangement of the power module 3 and the first capacitor core 2 along the thickness direction of the housing 1 utilizes the space in that direction, resulting in a smaller horizontal space occupied by the first capacitor core 2 and the power module 3. This improves the structural compactness of the electrical component module 1000, reduces its horizontal volume, and facilitates its placement within the motor controller, thus reducing the size of the motor controller.

[0092] To meet the insulation requirements of the electrical component module 1000, optionally, as shown in Figures 1 and 3 to 5, the housing 1 has a filling port 102 and a first plate 103 opposite to the filling port 102 along a first direction. The filling port 102 is used to fill the housing 1 with insulating filler material. The first capacitor core 2 and the power module 3 are located on both sides of the first plate 103, and the first opening 101 is formed on the first plate 103.

[0093] After the electrical component module 1000 is assembled, insulating filler material can be injected into the interior of the housing 1 of the electrical component module 1000 through the potting port 102. On the one hand, the insulating filler material can fix the various components inside the housing 1, effectively preventing the components installed inside the housing 1 from shaking. On the other hand, the insulating filler material filled into the housing 1 can also insulate the components installed inside the housing 1, effectively preventing the components installed inside the housing 1 (such as the first capacitor core 2, the first busbar 401, the second busbar 501, the first connector 405, the second connector 505, the relay 18, the fuse 22, etc.) from coming into contact with each other and short-circuiting, affecting the normal use of the electrical component module 1000, and even easily damaging the electrical component module 1000 and the motor controller using the electrical component module 1000.

[0094] Furthermore, since the first opening 101 is formed on the first plate 103 for arranging the first capacitor core 2 and the power module 3, the first connecting component 4 and the second connecting component 5 only need to pass through the first opening 101 to connect the first capacitor core 2 and the power module 3. This is beneficial to shorten the length of the first connecting component 4 and the second connecting component 5, thereby reducing the stray inductance generated by the first capacitor core 2 and the power module 3.

[0095] Furthermore, since the first plate 103 and the potting port 102 are located on both sides of the housing 1 along the first direction, when the electrical component module 1000 is assembled and the insulating filler material is injected into the housing 1 through the potting port 102, the first connecting component 4 and the second connecting component 5 will not obstruct the insulating filler material. This is beneficial for the insulating filler material to flow in the housing 1, thereby improving the filling effect of the insulating filler material in the housing 1.

[0096] Optionally, as shown in FIG1, the first direction can be the thickness direction of the shell 1, that is, the filling port 102 and the first plate 103 are opposite each other along the thickness direction of the shell 1.

[0097] Furthermore, to cool the first capacitor core 2 and the power module 3, optionally, as shown in Figures 1, 4, 5, and 7, the housing 1 has a heat dissipation section 104 for cooling the first capacitor core 2 and the power module 3. Since the heat dissipation section 104 can dissipate heat from the first capacitor core 2 and the power module 3, during operation, the first capacitor core 2 and the power module 3 can always operate within a suitable temperature range, thereby effectively preventing damage to the first capacitor core 2 and the power module 3 and extending their service life.

[0098] Furthermore, since the first capacitor core 2 and the heat dissipation module are integrated into the housing 1 and cooled by the same heat dissipation part 104, the electrical component module 1000 provided in this disclosure does not require multiple different heat dissipation structures. The heat dissipation of the first capacitor core 2 and the power module 3 can be achieved simultaneously through the same heat dissipation part 104. This effectively avoids the increased size and structural complexity of the electrical component module 1000, which would otherwise require multiple different heat dissipation structures to cool the first capacitor core 2 and the power module 3.

[0099] In the electrical component module 1000 provided in this disclosure, the first capacitor core 2, the power module 3, and the heat dissipation part 104 can have any appropriate positional relationship. For example, the first capacitor core 2 and the power module 3 can be located on the same side of the heat dissipation part 104, or the first capacitor core 2 and the power module 3 can be located on different sides of the heat dissipation part 104. This disclosure does not limit this.

[0100] As one embodiment of this disclosure, as shown in Figures 1, 3, 5, and 7, the first capacitor core 2 and the power module 3 are located on opposite sides of the heat dissipation section 104. In other words, the first capacitor core 2 and the power module 3 are located on different sides of the heat dissipation section 104, forming a "sandwich" structure. The compact arrangement of the first capacitor core 2, the power module 3, and the heat dissipation section 104 is beneficial for improving the volumetric density and power density of the electrical component module 1000. At the same time, it can also reduce the volume of the heat dissipation section 104, thereby avoiding an increase in the volume and cost of the electrical component module 1000 due to an excessively large heat dissipation section 104.

[0101] It should be noted that this disclosure does not limit the specific type of the heat dissipation part 104, as long as the heat dissipation part 104 can cool the first capacitor core 2 and the power module 3. For example, the heat dissipation part 104 can be a fan, or it can be a structure or material that can absorb heat, etc., and this disclosure does not limit it in this regard.

[0102] In one embodiment of this disclosure, the heat dissipation section 104 is provided with a first flow channel for the cooling medium to flow through, and the housing 1 is provided with a cooling medium inlet 105 and a cooling medium outlet 106 communicating with the first flow channel. Thus, the cooling medium can flow into the first flow channel through the cooling medium inlet 105 on the housing 1, and after exchanging heat with the first capacitor core 2 and the power module 3, it flows out from the cooling medium outlet 106. The flowing cooling medium has a good heat dissipation effect, which is beneficial to improving the heat dissipation effect of the first capacitor core 2 and the power module 3.

[0103] It should be noted that in the electrical device module 1000 provided in this disclosure, the cooling medium can be any cooling medium suitable for dissipating heat from the first capacitor core 2 and the power module 3. For example, the cooling medium can be a refrigerant or a coolant, and this disclosure does not limit it.

[0104] To further improve the heat dissipation effect of the heat dissipation unit 104 on the power module 3, optionally, as shown in Figures 1 and 5 to 7, the power module 3 may have a heat dissipation pin 305, which is inserted into the first flow channel. Since the heat dissipation pin 305 can be inserted into the first flow channel, during use, the cooling medium flowing through the first flow channel can directly flush the heat dissipation pin 305, thereby dissipating heat from the power module 3. The heat dissipation pin 305, which is in direct contact with the cooling medium, can improve the heat dissipation effect of the heat dissipation unit 104 on the power module 3, thus helping to ensure that the heat dissipation module operates within a reasonable temperature range.

[0105] In the electrical component module 1000 provided in this disclosure, the heat dissipation part 104 can be disposed at any suitable location on the housing 1. For example, the heat dissipation part 104 can be disposed inside the housing 1, or it can be disposed outside the housing 1, or the heat dissipation part 104 itself can be part of the housing 1. This disclosure does not limit this. For example, in an embodiment where both the power module 3 and the first capacitor core 2 are disposed inside the housing 1, the aforementioned heat dissipation part 104 can be disposed inside the housing 1.

[0106] As one embodiment of this disclosure, as shown in Figures 1 to 5 and Figure 7, the housing 1 includes a first plate 103 and a plurality of second plates 107 surrounding the first plate 103. The first plate 103 and the second plates 107 together form a receiving cavity 108. The first capacitor core 2 is located inside the receiving cavity 108. The power module 3 is located on the side of the first plate 103 away from the receiving cavity 108 and is installed on the first plate 103. The first plate 103 has a heat dissipation part 104.

[0107] Since the first capacitor core 2 is located on the side of the first plate 103 close to the receiving cavity 108, and the power module 3 is located on the side of the first plate 103 away from the receiving cavity 108, and the heat dissipation part 104 is part of the first plate 103, that is, the first plate 103 can both serve as part of the shell 1 and together with the second plate 107 to form the receiving cavity 108, and the first plate 103 also has a heat dissipation part 104 to cool the first capacitor core 2 and the power module 3, so that the overall integration of the electrical device module 1000 is high and the structure is compact, which is conducive to further improving the volume density and power density of the electrical device module 1000.

[0108] In addition, since the first capacitor core 2 is located in the cavity 108 formed by the first plate 103 and the multiple second plates 107, the first plate 103 and the multiple second plates 107 can protect the first capacitor core 2, effectively preventing the first capacitor core 2 from colliding with other components in the motor controller and being damaged.

[0109] For embodiments where the heat dissipation part 104 has a first flow channel and the heat dissipation part 104 is part of the first plate 103, this disclosure does not limit the specific formation method of the first flow channel on the first plate 103. As one embodiment of this disclosure, the first plate 103 may include a first plate body 1031, a first flow channel groove formed on the first plate body 1031, and a first cover plate 1033. The first cover plate 1033 covers the opening of the first flow channel groove, so that the first cover plate 1033 and the groove wall of the first flow channel groove together form the first flow channel.

[0110] As another embodiment of this disclosure, the first flow channel can be directly formed within the first plate body 1031.

[0111] To ensure that the power module 3 remains in close contact with the heat sink 104, optionally, as shown in Figures 5 and 6, the electrical component module 1000 further includes a pressure block 6 and a threaded fastener 7. The heat sink 104 has a threaded hole 1041. The pressure block 6 is used to press the power module 3 firmly onto the heat sink 104, and the threaded fastener 7 passes through the pressure block 6 and connects to the threaded hole 1041. Thus, on the one hand, the pressure block 6 and the threaded fastener 7 can fix the power module 3, effectively preventing the power module 3 from shaking and affecting the normal operation of the electrical component module 1000; on the other hand, the pressure block 6 can also keep the power module 3 firmly pressed onto the heat sink 104, which helps to ensure the heat dissipation effect of the heat sink 104 on the power module 3.

[0112] Optionally, as shown in Figures 1 to 5 and Figure 7, at least one second plate 107 is provided with a second flow channel communicating with the first flow channel. The second flow channel can cool the internal space of the receiving cavity 108, thereby cooling the devices within the receiving cavity 108, such as the first capacitor core 2 or the fuse 22 and relay 18 mentioned below. In addition, the second flow channel can also dissipate heat from devices (such as the fuse 22 and relay 18 mentioned below) arranged near the second plate 107.

[0113] As one embodiment of this disclosure, as shown in Figures 1 to 5 and Figure 7, the plurality of second plates 107 include a first side plate 1072 and a second side plate 1073. The electrical component module 1000 may further include a relay 18 and a fuse 22. Both the relay 18 and the fuse 22 are disposed within the receiving cavity 108 of the housing 1. The relay 18 is adjacent to the first side plate 1072, and the fuse 22 is adjacent to the intersection of the first side plate 1072 and the second side plate 1073. A second flow channel is provided in both the first side plate 1072 and the second side plate 1073. In this way, the cooling medium in the second flow channel in the first side plate 1072 can cool the relay 18, and the cooling medium in the second flow channel in the first side plate 1072 and the second side plate 1073 can cool the fuse 22.

[0114] This disclosure does not limit the specific way in which the second flow channel is formed on the second plate 107. As one embodiment of this disclosure, the second plate 107 may also include a second plate body 1074, a second flow channel groove formed on the second plate body 1074, and a second cover plate 1076. The second cover plate 1076 covers the opening of the second flow channel groove, thereby defining the second flow channel together with the groove wall of the second flow channel groove.

[0115] As another embodiment of this disclosure, the second flow channel may also be directly formed within the second plate 107.

[0116] In this disclosure, the housing 1 can be made of a metallic material. On the one hand, a housing 1 made of a metallic material has high strength and is not easily damaged, which is beneficial to improving the service life of the electrical component module 1000; on the other hand, a housing 1 made of a metallic material has high thermal conductivity, which is beneficial to further improve the heat dissipation effect of the various components (such as the first capacitor core 2 and the power module 3) within the electrical component module 1000; furthermore, in the embodiment where the heat dissipation part 104 is part of the housing 1, a housing 1 made of a metallic material allows the first capacitor core 2 and the power module 3 to make thermally conductive contact with the heat dissipation part 104.

[0117] To enable the aforementioned electrical component module 1000 to operate under high-power conditions, optionally, as shown in Figures 3 and 13 to 17, there are multiple first capacitor cores 2. Multiple first capacitor cores 2 have a larger total equivalent capacitance, greater voltage stability, and lower ripple voltage, enabling operation under higher current and higher power conditions, and improving the overall reliability of the circuit.

[0118] Furthermore, by rationally designing multiple first capacitor core 2 models, for example, setting multiple first capacitor core 2 with larger capacitance values ​​and multiple first capacitor core 2 with smaller capacitance values, low-frequency noise and high-frequency noise in the circuit can be filtered out simultaneously, which helps the electrical component module 1000 to be applicable to circuits with a wider frequency range.

[0119] To facilitate the connection of multiple first capacitor cores 2, optionally, as shown in Figures 8 and 10 to 17, the first connection component 4 includes a first busbar 401, and the second connection component 5 includes a second busbar 501. One of the first busbar 401 and the second busbar 501 is connected to the positive terminal of the multiple first capacitor cores 2, and the other of the first busbar 401 and the second busbar 501 is connected to the negative terminal of the multiple first capacitor cores 2. The first busbar 401 is connected to the input terminal of the first power module 3, and the second busbar 501 is connected to the input terminal of the second power module 3. The first busbar 401 can simultaneously connect the positive or negative terminals of the multiple first capacitor cores 2 and connect to the input terminal of the first power module 3, and the second busbar 501 can simultaneously connect the negative or positive terminals of the multiple first capacitor cores 2 and connect to the input terminal of the second power module 3, thereby realizing the electrical connection between the multiple first capacitor cores 2 and the power module 3, and the connection between the multiple first capacitor cores 2 and the power module 3 is relatively simple.

[0120] It should be noted that this disclosure does not limit the specific connection method between the first busbar 401 and the second busbar 501 and the positive or negative terminal of the first capacitor core 2. As a first embodiment of this disclosure, as shown in Figures 8 and 10 to 17, the first busbar 401 can be connected to the positive terminal of the first capacitor core 2, and the second busbar 501 can be connected to the negative terminal of the first capacitor core 2. Alternatively, as a second embodiment of this disclosure, as shown in Figures 10 and 11, the first busbar 401 can also be connected to the negative terminal of the first capacitor core 2, and the second busbar 501 can be connected to the positive terminal of the first capacitor core 2.

[0121] Optionally, at least a portion of the first busbar 401 and at least a portion of the second busbar 501 are stacked. Since the current direction of the first busbar 401 is opposite to that of the second busbar 501, the stacking of at least a portion of the first busbar 401 and at least a portion of the second busbar 501 can make the magnetic field directions generated by the first busbar 401 and the second busbar 501 due to electromagnetic induction opposite. The magnetic field directions generated by the first busbar 401 and the second busbar 501 due to electromagnetic induction can cancel each other out, thereby reducing the stray inductance between the first capacitor core 2 and the power module 3.

[0122] Optionally, as shown in FIG8 and FIG10 to FIG17, the first busbar 401 may include a first main body 402, a first extension 403 and a first connecting part 404, and the second busbar 501 includes a second main body 502, a second extension 503 and a second connecting part 504. The first main body 402 and the second main body 502 are spaced apart along a first direction. The first capacitor core 2 is located between the first main body 402 and the second main body 502. One of the first main body 402 and the second main body 502 is connected to the positive terminal of a plurality of first capacitor cores 2, and the other of the first main body 402 and the second main body 502 is connected to the negative terminal of a plurality of first capacitor cores 2. The first connecting part 404 is used to connect to the input terminal of the first power module 3. The first extension 403 is connected between the first main body 402 and the first connecting part 404. The second connecting part 504 is used to connect to the input terminal of the second power module 3. The second extension 503 is connected between the second main body 502 and the second connecting part 504. Thus, by simply connecting the first main body 402 and the second main body 502 to the positive and negative terminals of the plurality of first capacitor cores 2 respectively, and connecting the first connecting part 404 and the second connecting part 504 to the input terminals of the first power module 3 respectively, the electrical connection between the plurality of first capacitor cores 2 and the power module 3 can be realized.

[0123] Optionally, the first extension 403 and the second extension 503 are located on the same side of the first main body 402 and the second main body 502. Since the first extension 403 and the second extension 503 are located on the same side of the first main body 402 and the second main body 502, the distance between the first connecting portion 404 and the second connecting portion 504 respectively provided at one end of the first extension 403 and the second extension 503 can be closer, thereby facilitating connection with the power module 3.

[0124] Here, it can be understood that, in the embodiment where the first capacitor core 2 is located inside the housing 1 and the power module 3 is located outside the housing 1, the first main body 402 and the second main body 502 are located inside the housing 1, the first connecting part 404 and the second connecting part 504 are located outside the housing 1, and the first extension part 403 and the second extension part 503 can serve to lead out and connect, thereby connecting the first main body 402 and the first connecting part 404 of the first busbar 401, and connecting the second main body 502 and the second connecting part 504 of the second busbar 501.

[0125] Optionally, as shown in Figures 8 and 10 to 17, a first through hole 4021 can be formed on the first main body 402, and a second through hole 5021 can be formed on the second main body 502. The first through hole 4021 and the second through hole 5021 allow insulating filler material to pass through. Thus, when the electrical device module 1000 is assembled and insulating filler material is injected into the housing 1 through the potting port 102, the insulating filler material can flow through the first through hole 4021 and the second through hole 5021 into the gaps between the multiple first capacitor cores 2 and between the multiple first capacitor cores 2 and the housing 1. This achieves insulation between the multiple first capacitor cores 2 and between the multiple first capacitor cores 2 and the housing 1, resulting in better insulation performance of the electrical device module 1000 and reducing the likelihood of short circuits.

[0126] In order to reduce the stray inductance between the first capacitor core 2 and the power module 3 and improve the anti-interference capability of the electrical device module 1000, optionally, as shown in FIG8 and FIG10 to FIG17, the first extension 403 of at least part of the first busbar 401 and the second extension 503 of at least part of the second busbar 501 are stacked along the second direction (that is, the projection of the first extension 403 along the second direction and the projection of the second extension 503 along the second direction at least partially coincide), and the second direction intersects the first direction.

[0127] Since the first extension 403 and the second extension 503 are stacked on each other or at least partially stacked on each other, and the current flowing through the first extension 403 and the second extension 503 is in the opposite direction, the magnetic fields generated by the first extension 403 and the second extension 503 due to electromagnetic induction are in the opposite direction. The magnetic fields generated by the first extension 403 and the second extension 503 due to electromagnetic induction can cancel each other out, thereby reducing the stray inductance between the first capacitor core 2 and the power module 3.

[0128] As one embodiment of this disclosure, the first direction may be the thickness direction of the housing 1, and the second direction may be the length direction or the width direction of the housing 1.

[0129] Optionally, as shown in Figures 10 to 12, 14, 16, and 17, the first connecting portion 404 extends from the first extension 403 in a direction away from the second extension 503, and the second connecting portion 504 extends from the second extension 503 in a direction away from the first extension 403. In other words, the first connecting portion 404 extends in a direction away from the second connecting portion 504, and the second connecting portion 504 extends in a direction away from the first connecting portion 404. The mutually opposite first connecting portion 404 and second connecting portion 504 do not occupy the space between the first extension 403 and the second extension 503, thereby shortening the distance between the first extension 403 and the second extension 503. The smaller spacing between the first extension 403 and the second extension 503 ensures that the magnetic fields generated by the first extension 403 and the second extension 503 cancel each other out, thereby reducing the stray inductance generated by the first extension 403 and the second extension 503.

[0130] In other embodiments of this disclosure, the first connecting portion 404 and the second connecting portion 504 may also be stacked on top of each other. For example, the first connecting portion 404 and the second connecting portion 504 may be stacked along a first direction. Since the current directions of the first connecting portion 404 and the second connecting portion 504 are opposite and they are stacked on top of each other, the magnetic fields generated by the electromagnetic induction phenomenon of the first connecting portion 404 and the second connecting portion 504 are opposite in direction and can also cancel each other out, which is beneficial to further reduce the stray inductance between the first capacitor core 2 and the power module 3.

[0131] To prevent a short circuit between the first busbar 401 and the second busbar 501, the aforementioned electrical component module 1000 may optionally include a first insulating member 8, which insulates the first busbar 401 and the second busbar 501 from each other. Because the first insulating member 8 insulates the first busbar 401 and the second busbar 501 from each other, it avoids the possibility of a short circuit between the first busbar 401 and the second busbar 501 due to the small distance between them.

[0132] For example, the first insulating member 8 can insulate the first extension 403 of the first busbar 401 and the second extension 503 of the second busbar 501 from each other, thereby avoiding the situation where the first extension 403 and the second extension 503 are easily short-circuited due to the small distance between them.

[0133] This disclosure does not limit the specific structure of the first insulating member 8. The first insulating member 8 may be an insulating sheet disposed between the first extension 403 and the second extension 503, or the first insulating member 8 may be an insulating layer coated on the surface of the first extension 403 and the second extension 503.

[0134] As one embodiment of this disclosure, as shown in Figures 12 and 17, the first insulating member 8 includes a wrapping portion 801 and a first insulating portion disposed within the wrapping portion 801. At least a portion of the first extension 403 and at least a portion of the second extension 503 are wrapped within the wrapping portion 801, and the first insulating portion is located between the first extension 403 and the second extension 503. The first insulating portion can achieve insulation between the first extension 403 and the second extension 503, thereby preventing a short circuit between the first extension 403 and the second extension 503.

[0135] Furthermore, since at least a portion of the first extension 403 and at least a portion of the second extension 503 can be enclosed within the enclosure 801, the first insulating member 8 can, on the one hand, insulate the first busbar 401 and the second busbar 501, preventing short circuits between them; on the other hand, it can also connect and fix the first busbar 401 and the second busbar 501. When the first insulating member 8 is provided on the first extension 403 and the second extension 503, the first busbar 401 and the second busbar 501 connected by the first insulating member 8 can form a whole, facilitating connection with the first core unit. The assembly between the first busbar 401, the second busbar 501 and the first core unit is relatively simple.

[0136] Furthermore, the wrapping portion 801 can also prevent the first extension portion 403 and the second extension portion 503 from contacting other components inside the motor controller, thereby insulating the first extension portion 403 and the second extension portion 503 from other components inside the motor controller (such as the housing 1 made of metal material), further improving the lifespan of the electrical component module 1000 and the motor controller using the electrical component module 1000.

[0137] Optionally, the first insulating element 8 can be formed on the first extension 403 and the second extension 503 by injection molding. The injection-molded first insulating element 8 does not need to be installed separately, and can be formed on the first extension 403 and the second extension 503 in one injection molding process, which helps to simplify the assembly process of the first busbar 401 and the second busbar 501 on the electrical component module 1000.

[0138] Optionally, as shown in Figures 1, 7, 12, 14, 16, and 17, the first capacitor core 2, the first main body 402, and the second main body 502 are located inside the housing 1, while the power module 3, the first connecting part 404, and the second connecting part 504 are located outside the housing 1. A first opening 101 is formed on the housing 1, and the first extension 403 and the second extension 503 pass through the first opening 101. The wrapping part 801 is configured to seal the gap between the first extension 403 and the first opening 101, as well as the gap between the second extension 503 and the first opening 101.

[0139] Because the wrapping portion 801 is designed to seal the gap between the first extension portion 403 and the second extension portion 503 and the first opening 101, the first insulating member 8 can achieve insulation between the first extension portion 403 and the second extension portion 503, as well as insulation between the first extension portion 403 and the second extension portion 503 and the housing 1. In addition, it can also seal the first opening 101. Thus, on the one hand, during use, dust and other impurities are less likely to enter the interior of the housing 1 through the first opening 101, which helps ensure the normal operation of the electrical component module 1000; on the other hand, when insulating filler material is poured into the housing 1 through the potting port 102 on the housing 1, the wrapping portion 801 can block the insulating filler material, effectively preventing the insulating filler material from leaking from the first opening 101 and affecting the insulation effect of the components installed in the housing 1.

[0140] To ensure good insulation between the first busbar 401 and the second busbar 501, optionally, as shown in Figures 12, 14, 16, and 17, the first insulating member 8 further includes a second insulating portion 802. The second insulating portion 802 is located between the first connecting portion 404 and the second connecting portion 504, and protrudes from the first extending portion 403 and the second extending portion 503 in a direction away from them. The second insulating portion 802, protruding from the first connecting portion 404 and the second connecting portion 504 in a direction away from them, provides creepage insulation for the first connecting portion 404 and the second connecting portion 504. This effectively prevents the first connecting portion 404 and the second connecting portion 504 from easily experiencing arc creepage, high-voltage arcing, or even short circuits due to their close proximity, further improving the insulation effect between the first busbar 401 and the second busbar 501.

[0141] Optionally, the first connecting portion 404 may protrude from the first extension portion 403 along the second direction, the second connecting portion 504 may protrude from the second extension portion 503 along the second direction, and the first connecting portion 404 and the second connecting portion 504 are arranged side by side and opposite to each other along the second direction. The second insulating portion 802 may extend along the first direction and protrude from the first connecting portion 404 and the second connecting portion 504. The connection between the mutually opposite first connecting portion 404 and the second connecting portion 504 and the power module 3 is more convenient, and insulation can be achieved through the second insulating portion 802.

[0142] This disclosure does not limit the specific structure of the first extension 403. In order to reduce the stray inductance generated by the first extension 403 while facilitating connection with the first capacitor core 2, optionally, as shown in Figures 8, 10, and 11, the first extension 403 or the second extension 503 includes a first portion 4031 and a second portion 4032. For example, as shown in Figure 10, when at least a portion of the first busbar 401 is located below the second busbar 501, the first extension 403 includes a first portion 4031 and a second portion 4032. As shown in Figure 11, when at least a portion of the second busbar 501 is located below the first busbar 401, the second extension 503 may include a first portion 4031 and a second portion 4032. The first portion 4031 is located on the side of a portion of the plurality of first capacitor cores 2, and the second portion 4032 is located on the side of another portion of the plurality of first capacitor cores 2. The first portion 4031 protrudes from the second portion 4032 in a direction away from the first capacitor core 2. Both the first portion 4031 and the second portion 4032 can limit the movement of the first capacitor core 2 inside them, effectively preventing the first capacitor core 2 from moving and affecting the connection between the first capacitor core 2 and the first busbar 401 when they are connected.

[0143] Furthermore, for embodiments with different models and sizes of multiple first capacitor cores 2, by rationally designing the positional relationship between the first part 4031 and the second part 4032 in the above manner, the distance between the two parts of the first extension 403 (i.e., the first part 4031 and the second part 4032) and the multiple first capacitor cores 2 can be shortened. This can shorten the length of the circuit connecting the first capacitor core 2 and the power module 3. A shorter length results in lower stray inductance, which is beneficial for further reducing the stray inductance between the first capacitor core 2 and the power module 3.

[0144] Optionally, as shown in Figures 10 and 13, a third through hole 4033 is provided on the first portion 4031 of the first extension 403. Thus, when the electrical component module 1000 is assembled and insulating filler is injected into the housing 1 through the potting port 102, the insulating filler can flow through the third through hole 4033 to the multiple first capacitor cores 2 and between the multiple first capacitor cores 2 and the first extension 403, thereby achieving insulation between the multiple first capacitor cores 2 and between the multiple first capacitor cores 2 and the first extension 403. The electrical component module 1000 has good insulation performance and is less prone to short circuits.

[0145] To facilitate the connection of the first busbar 401 and the second busbar 501 to the power module 3, optionally, as shown in Figures 1, 2, and 19, the first connection assembly 4 further includes a first connector 405, and the second connection assembly 5 further includes a second connector 505. One end of the first connector 405 is connected to the first busbar 401, and the other end is connected to the input terminal of the first power module 3. One end of the second connector 505 is connected to the second busbar 501, and the other end is connected to the input terminal of the second power module 3. The first connector 405 and the second connector 505 can respectively realize the electrical connection between the first busbar 401 and the second busbar 501 and the power module 3, thereby connecting the first capacitor core 2 to the power module 3.

[0146] In the embodiment where the first insulating member 8 includes a wrapping portion 801, to prevent displacement of the first connector 405 and / or the second connector 505 during connection, optionally, as shown in FIG14, a positioning post 8011 is provided on the wrapping portion 801, and positioning holes 506 are provided on the first and second electrical connectors. Thus, when the first connector 405 is connected to the first busbar 401 or the power module 3, and when the second connector 505 is connected to the second busbar 501 or the power module 3, the positioning post 8011 and the positioning hole 506 cooperate to achieve positioning of the first connector 405 and the second connector 505, preventing displacement of the first connector 405 and the second connector 505, and ensuring reliable connection between the first connector 405 and the first busbar 401 or the power module 3, and between the second connector 505 and the second busbar 501 or the power module 3.

[0147] To further reduce stray inductance between the first capacitor core 2 and the power module 3, optionally, as shown in Figures 1 and 2, at least a portion of the first connector 405 and at least a portion of the second connector 505 are stacked along a first direction.

[0148] Here, it should be noted that the above-mentioned stacking of at least a portion of the first connector 405 and at least a portion of the second electrical connector along the first direction means that the projection of the first connector 405 along the first direction and the projection of the second electrical connector along the first direction at least partially coincide.

[0149] Since the projection of the first connector 405 at least partially overlaps with the projection of the second electrical connector, and the current flowing through the first connector 405 and the second electrical connector is in opposite directions, the magnetic fields generated by the first connector 405 and the second electrical connector due to electromagnetic induction are in opposite directions. The magnetic fields generated by the first connector 405 and the second electrical connector due to electromagnetic induction can cancel each other out, thereby further reducing the stray inductance between the first connector 405 and the second electrical connector.

[0150] Optionally, as shown in Figures 8 and 19, the first busbar 401 has a first connecting portion 404, and the second busbar 501 has a second connecting portion 504. The first connecting portion 404 and the second connecting portion 504 are arranged side by side along a second direction, which intersects with the first direction. The first connector 405 includes a first overlapping portion 407, a conductive portion 408, and a first capacitor output terminal 409. The conductive portion 408 is located between the first overlapping portion 407 and the first capacitor output terminal 409. The first overlapping portion 407 overlaps with the first connecting portion 404, and the first capacitor output terminal 409 overlaps with the input terminal of the first power module 3. The second connector 505 includes a second overlapping portion 507 and a second capacitor output terminal 508. The second overlapping portion 507 overlaps with the second connecting portion 504, and the second capacitor output terminal 508 overlaps with the input terminal of the second power module 3. At least a portion of the conductive portion 408 and at least a portion of the second overlapping portion 507 are stacked along the first direction.

[0151] Thus, by simply connecting the first lap portion 407 and the first capacitor output terminal 409 to the first connection portion 404 and the first power module 3 input terminal respectively, and connecting the second lap portion 507 and the second capacitor output terminal 508 to the second connection portion 504 and the second power module 3 input terminal respectively, the electrical connection between the first busbar 401 and the first connector 405 and the second busbar 501 and the second connector 505 can be realized.

[0152] Furthermore, since the first overlapping portion 407 and the first connecting portion 404, the second overlapping portion 507 and the second connecting portion 504, the first capacitor output terminal 409 and the first power module 3 input terminal, and the second capacitor output terminal 508 and the second power module 3 input terminal are all interconnected, on the one hand, the contact area between the interconnected first overlapping portion 407 and the first connecting portion 404, the second overlapping portion 507 and the second connecting portion 504, the first capacitor output terminal 409 and the first power module 3 input terminal, and the second capacitor output terminal 508 and the second power module 3 input terminal is large, enabling the passage of a large current and providing a large power; on the other hand, the interconnected first overlapping portion 407 and the first connecting portion 404, the second overlapping portion 507 and the second connecting portion 504, the first capacitor output terminal 409 and the first power module 3 input terminal, and the second capacitor output terminal 508 and the second power module 3 input terminal can be connected using melting processes such as laser welding, or riveting processes, making the connection relatively convenient.

[0153] In the embodiment where the first insulating member 8 includes a second insulating portion 802, and the second insulating portion 802 protrudes from the first connecting portion 404 and the second connecting portion 504 in a direction away from the first extension portion 403 and the second extension portion 503, to avoid the second insulating portion 802, optionally, as shown in FIG19, the first connecting member 405 may also include a clearance portion 410. One end of the clearance portion 410 is connected to the first overlapping portion 407, and the other end of the clearance portion 410 is connected to the conductive portion 408. The clearance portion 410 is bent into a U-shape in a direction away from the first extension portion 403 and the second extension portion 503. The U-shaped clearance portion 410 will not interfere with the second insulating portion 802, thereby enabling the connection between the power module 3 and the first connecting portion 404.

[0154] Optionally, the power module 3 may include a plurality of first power module 3 input terminals and a plurality of second power module 3 input terminals, which are spaced apart along a third direction, intersecting the first and second directions. The first connector 405 includes a plurality of first capacitor output terminals 409, which are arranged one-to-one with the plurality of first power module 3 input terminals. The second connector 505 includes a plurality of second capacitor output terminals 508, which are arranged one-to-one with the plurality of second power module 3 input terminals.

[0155] To insulate the first connector 405 and the second connector 505, optionally, as shown in Figures 1 and 21, the above-mentioned electrical component module 1000 further includes a second insulating member 23. The second insulating member 23 includes a first insulating part 231 and a second insulating part 232. The first insulating part 231 is located between the conductive part 408 and the second overlapping part 507, and the second insulating part 232 is located between the first capacitor output terminal 409 and the first power module 3 input terminal and the second capacitor output terminal 508 and the second power module 3 input terminal.

[0156] Thus, insulation between the first connector 405 and the second connector 505 can be achieved through the first insulating part 231, effectively preventing short circuits between the first connector 405 and the second connector 505, which would affect the normal use of the electrical component module 1000 and even easily damage the electrical component module 1000 and the motor controller using the electrical component module 1000.

[0157] Furthermore, since the second insulating part 232 is located between the first capacitor output terminal 409 and the first power module 3 input terminal and the second capacitor output terminal 508 and the second power module 3 input terminal, the second insulating part 232 can achieve insulation between the multiple capacitor output terminals and the multiple power module 3 input terminals, and short circuits are not easily formed between the first connector 405 and the second connector 505, as well as between the multiple power module 3 input terminals.

[0158] To improve the practicality of the electrical component module 1000, optionally, as shown in Figures 13 to 17, the electrical component module 1000 further includes a second capacitor core 9 and a third connection component 10. The second capacitor core 9 is installed in the housing 1 and is adjacent to the first capacitor core 2. The third connection component 10 is connected to the positive terminal of the second capacitor core 9. One of the first busbar 401 and the second busbar 501 is connected to the negative terminal of the first capacitor core 2 and the negative terminal of the second capacitor core 9.

[0159] The second capacitor core 9 and the first capacitor core 2 work together to enable the electrical device module 1000 to have different operating conditions. For example, one of the first capacitor core 2 and the second capacitor core 9 can be connected to an external load, while the other of the first capacitor core 2 and the second capacitor core 9 can be disconnected from the external load. Alternatively, both the first capacitor core 2 and the second capacitor core 9 can be connected to an external load. This improves the practicality of the electrical device module 1000.

[0160] In this disclosure, the first capacitor core 2 and the second capacitor core 9 can have any suitable type. For example, the first capacitor core 2 and the second capacitor core 9 can both be driving capacitor cores. The first capacitor core 2 and the second capacitor core 9 cooperate with each other to improve the overall capacitance of the electrical device module 1000 and enable the electrical device module 1000 to have better voltage stability.

[0161] In one embodiment of this disclosure, the first capacitor core 2 is a drive capacitor core, and the second capacitor core 9 is a boost capacitor core. The drive capacitor core and the boost capacitor core work together to meet the usage requirements of the electrical device module 1000 under both high and low voltage conditions. For example, when a motor controller using this electrical device module 1000 is applied to a vehicle, by disconnecting or turning off the boost capacitor from the external load, the vehicle can have both slow charging and fast charging operating modes.

[0162] To facilitate connection of the electrical component module 1000 to an external load, optionally, as shown in Figures 1, 7, 12, 14, 16, and 17, the electrical component module 1000 further includes a first external terminal 11, a second external terminal 12, and a third external terminal 13. The first external terminal 11, the second external terminal 12, and the third external terminal 13 are disposed on the housing 1. The first busbar 401 and the second busbar 501 connected to the positive terminal of the first capacitor core 2 are the positive busbars, and the first busbar 401 and the second busbar 501 connected to the negative terminal of the first capacitor core 2 are the negative busbars. The positive busbar is connected to the first external terminal 11, the third connection component 10 is connected to the second external terminal 12, and the negative busbar is connected to the third external terminal 13. The first external terminal 11, the second external terminal 12, and the third external terminal 13 enable the connection between the first capacitor core 2 and the second capacitor core 9 and the external load, making the connection between the first capacitor core 2 and the second capacitor core 9 and the external load (such as a battery pack) relatively convenient.

[0163] Optionally, as shown in Figures 1, 7, 12, 14, 16, and 17, the first external terminal 11, the second external terminal 12, and the third external terminal 13 are all disposed on the same side of the housing 1 and spaced apart along a third direction. In this way, by rationally designing the specific positions of the multiple terminals (i.e., the first external terminal 11, the second external terminal 12, and the third external terminal 13) on the housing 1, the positions of the multiple terminals and the output connectors of the external load can be adapted to each other. This shortens the length of the electrical connection strip 21 between the multiple terminals and the output connectors of the external load, thereby simplifying the connection complexity between the electrical component module 1000 and the external load.

[0164] This disclosure does not limit the specific connection method between the first external terminal 11 and the positive busbar. As a first embodiment of this disclosure, as shown in FIG10, the first busbar 401 is the positive busbar, the second busbar 501 is the negative busbar, and the first extension 403 of the first busbar 401 is disposed on the side of the second extension 503 of the second busbar 501 near the first external terminal 11. The electrical component module 1000 may further include a first intermediate connection bar 14, one end of which is connected to the positive busbar, that is, the other end of the first busbar 401 and the first intermediate connection bar 14 is connected to the first external terminal 11. In this way, the connection between the first external terminal 11 and the positive busbar can be realized through the first intermediate connection bar 14.

[0165] As a second embodiment of this disclosure, as shown in FIG11, the first busbar 401 is a negative busbar, and the second busbar 501 is a positive busbar. The first extension 403 of the first busbar 401 is disposed on the side of the second extension 503 of the second busbar 501 near the first external terminal 11. A cross-connection hole 5031 is provided on the first extension 403. The electrical component module 1000 may further include a first intermediate connection busbar 14. One end of the first intermediate connection busbar 14 can pass through the cross-connection hole 5031 and be connected to the positive busbar. That is, the other end of the second busbar 501 and the first intermediate connection busbar 14 are connected to the first external terminal 11. Since the first intermediate connection busbar 14 can pass through the cross-connection hole 5031 and be connected to the positive busbar, the connection between the first external terminal 11 and the positive busbar can be achieved without increasing the length of the first intermediate connection busbar 14. This effectively avoids the situation where the length of the first intermediate connection busbar 14 increases because it needs to go around one side of the negative busbar and be connected to the positive busbar.

[0166] This disclosure does not limit the connection relationship between the third external terminal 13 and the negative busbar. In a first embodiment of this disclosure, the first busbar 401 is the positive busbar, and the second busbar 501 is the negative busbar. The first busbar 401 is closer to the third external terminal 13 than the second busbar 501. The electrical component module 1000 may further include a fourth intermediate connecting busbar 15. The second busbar 501, i.e., the negative busbar, is bent at one end in a third direction to form an external connecting portion 4011. One end of the fourth intermediate connecting busbar 15 is connected to the third external terminal 13, and the other end of the fourth intermediate connecting busbar 15 is connected to the external connecting portion 4011. Thus, the electrical connection between the third external terminal 13 and the negative busbar can be achieved through the fourth intermediate connecting busbar 15.

[0167] In another embodiment of this disclosure, the first busbar 401 is a negative busbar and the second busbar 501 is a positive busbar. The first busbar 401 is closer to the third external terminal 13 than the second busbar 501. The electrical device module 1000 may also include a fourth intermediate connection bar 15. One end of the fourth intermediate connection bar 15 is connected to the third external terminal 13, and the other end of the fourth intermediate connection bar 15 is connected to the side of the first busbar 401 that is closer to the third external terminal 13.

[0168] This disclosure does not limit the specific structure of the third connection component 10. Optionally, as shown in Figures 12 and 13, the third connection component 10 includes a second intermediate connection bar 111 and a third intermediate connection bar 112. One end of the second intermediate connection bar 111 is connected to the second external terminal 12, and the other end of the second intermediate connection bar 111 is connected to the third intermediate connection bar 112. The third intermediate connection bar 112 is connected to the positive terminal of the second capacitor core 9. In this way, through the second intermediate connection bar 111 and the third intermediate connection bar 112, an electrical connection can be achieved between the positive terminal of the second capacitor core 9 and the second external terminal 12.

[0169] To further reduce the stray inductance of the electrical component module 1000, optionally, as shown in FIG12, the second intermediate connection bar 111 is bent into a "Z" shape. The "Z"-shaped second intermediate connection bar 111 can realize the connection between the second external terminal 12 and the third intermediate connection bar 112, and can avoid the first busbar 401 and the second busbar 501, so that the first busbar 401 and the second busbar 501 have a longer length, which helps to reduce the stray inductance of the first busbar 401 and the second busbar 501, thereby reducing the stray inductance of the electrical component module 1000.

[0170] To facilitate the connection of the first external terminal 11, the second external terminal 12, and the third external terminal 13 to an external load, optionally, as shown in Figures 1, 4, 5, and 7, the housing 1 is provided with a second opening 109 and a third opening 110. The first external terminal 11 and the second external terminal 12 pass through the second opening 109, and the third external terminal 13 passes through the third opening 110, so that the first external terminal 11, the second external terminal 12, and the third external terminal 13 can be located at least partially outside the housing 1.

[0171] The electrical component module 1000 also includes a third insulating member 16 and a fourth insulating member 17. The third insulating member 16 is used to insulate the first external terminal 11 and the second external terminal 12 from the housing 1, and the third insulating member 16 is configured to seal the gap between the first external terminal 11 and the second external terminal 12 and the second opening 109. The fourth insulating member 17 is used to insulate the third external terminal 13 from the housing 1, and the fourth insulating member 17 is configured to seal the gap between the third external terminal 13 and the third opening 110. Because the third insulating member 16 and the fourth insulating member 17 can achieve insulation between the first external terminal 11, the second external terminal 12, and the third external terminal 13 and the housing 1, the insulation of the first external terminal 11, the second external terminal 12, and the third external terminal 13 is good, and short circuits are less likely to occur. Furthermore, since the third insulating member 16 is configured to block the gap between the first external terminal 11 and the second external terminal 12 and the second opening 109, and the fourth insulating member 17 is configured to block the gap between the third external terminal 13 and the third opening 110, when the electrical component module 1000 is assembled and insulating filler material is injected into the housing 1 through the potting port 102, the third insulating member 16 and the fourth insulating member 17 can also block the insulating filler material, thereby improving the filling effect of the insulating filler material in the housing 1.

[0172] Optionally, the third insulating component 16 is formed on the first external terminal 11 and the second external terminal 12 by injection molding, and / or the fourth insulating component 17 is formed on the third external terminal 13 by injection molding. The injection-molded third insulating component 16 and fourth insulating component 17 do not need to be installed separately; they can be formed on the first external terminal 11 and the second external terminal 12 or the third external terminal 13 in a single injection molding process. This simplifies the assembly process of the first busbar 401 and the second busbar 501 on the electrical component module 1000.

[0173] To enable switching between different operating conditions of the electrical component module 1000, optionally, as shown in Figures 13 and 15, the electrical component module 1000 further includes a relay 18. The relay 18 is disposed inside the housing 1 and is connected to the first external terminal 11 and the second external terminal 12. Thus, by controlling the opening and closing of the relay 18, the connection or disconnection between the first capacitor core 2 and the second capacitor core 9 can be achieved, thereby enabling the electrical component module 1000 to operate under different conditions.

[0174] To facilitate control of relay 18, as shown in FIG18, relay 18 may optionally include control pin 183, which is adapted to be connected to the control board of motor controller, thereby enabling control of the working state of relay 18, and further enabling control of the conduction or disconnection between the first capacitor core 2 and the second capacitor core 9.

[0175] Optionally, the relay 18 can be located inside the housing 1, and the aforementioned control pin 183 can extend out of the housing 1 to facilitate connection with the control board of the motor controller.

[0176] Optionally, as shown in Figures 1, 7, and 12 to 17, the aforementioned electrical component module 1000 may further include a fourth external terminal 19, a fifth external terminal 20, and a connecting strip 21. The fourth external terminal 19 and the fifth external terminal 20 are disposed on the housing 1. One end of the connecting strip 21 is connected to the fourth external terminal 19, and the other end of the connecting strip 21 is connected to the fifth external terminal 20. The relay 18 is also connected to the fourth external terminal 19. Through the fourth external terminal 19 and the fifth external terminal 20, other devices (such as protection devices) within the motor controller can be connected to the electrical component module 1000, thereby enabling the electrical component module 1000 to have multiple functions and making it highly practical.

[0177] Optionally, the fourth external terminal 19 is located on the same side of the housing 1 as the first external terminal 11, the second external terminal 12 and the third external terminal 13, and the fifth external terminal 20 is arranged opposite to the fourth external terminal 19.

[0178] Optionally, the fourth external terminal 19 can be inserted through the second opening 109, and the fifth external terminal 20 can be inserted through the fourth opening 114 on the housing 1. The electrical component module 1000 may also be provided with a fifth insulating member 24 and a sixth insulating member 25. The fifth insulating member 24 is used to insulate the fourth external terminal 19 from the housing 1, and the sixth insulating member 25 is used to insulate the fifth external terminal 20 from the housing 1. The fifth insulating member 24 is configured to block the gap between the fourth external terminal 19 and the second opening 109, and the sixth insulating member 25 is configured to block the gap between the fifth external terminal 20 and the fourth opening 114.

[0179] Thus, after the electrical component module 1000 is assembled, when insulating filler material is injected into the housing 1 through the potting port 102, the fifth insulating member 24 and the sixth insulating member 25 can also act as a barrier to the insulating filler material, thereby improving the filling effect of the insulating filler material in the housing 1. The fifth insulating member 24 and the sixth insulating member 25 can also achieve insulation between the fourth external terminal 19 and the fifth external terminal 20 and the housing 1.

[0180] To improve the safety of the electrical component module 1000, optionally, as shown in Figures 3, 14, and 15, the electrical component module 1000 further includes a fuse 22. The fuse 22 is disposed inside the housing 1, with one end connected to the third external terminal 13 and the other end connected to the negative busbar. The fuse 22 can disconnect the negative busbar and the third external terminal 13 in the event of a circuit malfunction (such as a short circuit), thereby breaking the entire circuit and effectively improving the safety of the electrical component module 1000.

[0181] To avoid interference between the first capacitor core 2 and the fuse 22, optionally, as shown in Figures 3 and 4, a heat insulation plate 113 is also provided inside the housing 1. The heat insulation plate 113 is suitable for being disposed between the first capacitor core 2 and the fuse 22.

[0182] According to a second aspect of this disclosure, a motor controller is provided, including the electrical device module 1000 as described above.

[0183] The motor controller has all the beneficial effects of the aforementioned electrical component module 1000, which will not be elaborated here.

[0184] According to a third aspect of this disclosure, a vehicle is provided that includes the electrical device module 1000 as described above; or, includes the motor controller as described above, wherein the vehicle includes all the beneficial effects of the motor controller described above, which will not be repeated here.

[0185] This disclosure does not limit the type of vehicle, which may be a pure electric vehicle, a hybrid electric vehicle (range-extended electric vehicle), etc. This disclosure does not limit the type of vehicle.

[0186] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0187] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0188] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
