Detailed implementation manners

[0074] The following will describe the detailed implementation manners of the present disclosure in conjunction with the accompanying drawings. It should be understood that the detailed implementation manners described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0075] In the present disclosure, it should be understood that the orientation terms such as "upper, lower", etc. are defined based on the drawing direction of the drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, as well as a specific orientation structure and operation. Therefore, it should not be construed as a limitation to the present disclosure. The orientation terms such as "first direction, second direction, third direction" can be referred to Figure 1 , Figure 8 , Figures 10 to 12 , Figures 14 to 15 and Figure 17 as shown.

[0076] The terms "inner, outer" refer to the inside and outside of the corresponding structural contour. In addition, it should be noted that the terms such as "first", "second", etc. are used to distinguish one element from another, and do not have sequentiality and importance. Additionally, in the description with reference to the drawings, the same reference numerals in different drawings represent the same elements.

[0077] In the description of the present disclosure, it should also be noted that unless otherwise clearly specified and limited, the terms "arranged", "connected", "coupled", "installed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0078] As Figures 1 to 21 shown, according to the first aspect of the present disclosure, an electrical component module 1000 is provided, including a housing 1, a first capacitor core 2, and a power module 3. Among them, the first capacitor core 2 and the power module 3 are both installed in 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 circuit filtering and conversion.

[0079] 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, an integrated design of the first capacitor core 2 and the power module 3 is achieved. 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, and further can shorten the loop length between the first capacitor core 2 and the power module 3, and reduce the stray inductance between the first capacitor core 2 and the power module 3.

[0080] In addition, the first capacitor core 2 and the power module 3 with an integrated design are more compact in structure, have a smaller overall volume, occupy less space, and have a larger volume density and power density. On the one hand, it is beneficial to the arrangement of the electrical component module 1000 in the motor controller, helps to reduce the overall volume of the motor controller, and facilitates the arrangement of the motor controller in equipment (such as a vehicle); on the other hand, when the electrical component module 1000 is applied to the motor controller, it can also improve the volume density and power density of the motor controller.

[0081] Here, it should be noted that the above electrical component module 1000 can be applied to any suitable equipment, for example, it can be applied to a motor controller. In addition, the present disclosure does not limit the specific type of the above housing 1. The above housing 1 can be a housing 1 for installing the first capacitor core 2 and the power module 3, that is, the first capacitor core 2 and the power module 3 are installed in the housing 1 and are installed in the box body of the motor controller together with the housing 1. Alternatively, the above housing 1 can also be the box body of the motor controller, and the first capacitor core 2 and the power module 3 are directly integrated into the box body of the motor controller. The present disclosure does not limit this.

[0082] 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 electrode 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 electrode 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 can realize the electrical connection between the first capacitor core 2 and the power module 3.

[0083] In the present disclosure, the above first capacitor core 2 and 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. The present disclosure does not limit this.

[0084] For example, as Figure 1 and Figure 3 shown, as an exemplary embodiment of the present disclosure, the above 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 arranged outside the housing 1, there can be a relatively large operating space around the power module 3, which is convenient for electrically connecting the power module 3 and the first capacitor core 2.

[0085] Optionally, a first opening 101 is formed on the housing 1, and the first connection component 4 and the second connection component 5 pass through the first opening 101. In this way, when assembling the electrical component module 1000, the first capacitor core 2 can be first connected to the first connection component 4 and the second connection component 5, then the first capacitor core 2 is placed into the housing 1, and the first connection component 4 and the second connection component 5 are made to pass through the first opening 101, and then the power module 3 is connected to the first connection component 4 and the second connection component 5, thereby realizing the connection between the first capacitor core 2 and the power module 3. Since the power module 3 is arranged outside the housing 1, there can be a relatively large operating space around the power module 3, which can facilitate the connection between the first connection component 4 and the second connection component 5 and the power module 3. In other words, the power module 3 arranged outside the housing 1 can facilitate the connection with the first connection component 4 and the second connection 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.

[0086] In addition, the power module 3 arranged outside the housing 1 can also facilitate the connection with an external load (such as a motor). As Figure 1 and Figures 5 to 7 shown, an output pin 303 is provided on the above-mentioned power module 3, and the output pin 303 is located outside the housing 1, which can facilitate the connection between the output pin 303 and the external load.

[0087] To facilitate the control of the power module 3, optionally, as Figure 6 shown, a control pin 304 is also provided on the above-mentioned power module 3. Through the control pin 304, the electrical connection and signal transmission between the controller and the power module 3 can be realized, thereby enabling the control of the power module 3 and changing the output power and voltage of the power module 3. Since the power module 3 is located outside the housing 1 and the control pin 304 is also located outside the housing 1, it can facilitate the electrical connection between the control pin 304 and the controller.

[0088] Optionally, as Figure 1 、 Figure 3 and Figure 7 shown, the above-mentioned power module 3 and the first capacitor core 2 can be arranged at intervals along the thickness direction of the housing 1 (the first direction mentioned below). The power module 3 and the first capacitor core 2 arranged at intervals along the thickness direction of the housing 1 can utilize the space in the thickness direction of the housing 1, so that the space occupied by the first capacitor core 2 and the power module 3 in the horizontal direction of the housing 1 is relatively small, which is beneficial to improving the structural compactness of the electrical component module 1000, reducing the volume of the electrical component module 1000 in the horizontal direction, thereby facilitating the arrangement of the electrical component module 1000 in the motor controller and reducing the volume of the motor controller.

[0089] To meet the insulation requirements of the electrical component module 1000, optionally, as Figure 1 and Figures 3 to 5 shown, the above-mentioned housing 1 has a potting opening 102 and a first plate body 103 opposite to the potting opening 102 in the first direction. The potting opening 102 is used to pour an insulating filling material into the housing 1. The first capacitor core 2 and the power module 3 are respectively located on both sides of the first plate body 103, and a first opening 101 is formed in the first plate body 103.

[0090] After the electrical component module 1000 is assembled, the insulating filling material can be poured into the interior of the housing 1 of the electrical component module 1000 through the potting opening 102. On the one hand, the insulating filling material can fix the components in the housing 1 and effectively prevent the components installed in the housing 1 from shaking; on the other hand, the insulating filling material filled in the housing 1 can also insulate the components arranged in the housing 1, effectively preventing the components arranged in 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. mentioned below) from contacting each other and causing a short circuit, which affects the normal use of the electrical component module 1000 and even easily damages the electrical component module 1000 and the motor controller using the electrical component module 1000.

[0091] Moreover, since the first opening 101 is formed in the first plate body 103 for arranging the first capacitor core 2 and the power module 3, in this way, the first connection assembly 4 and the second connection assembly 5 only need to pass through the first opening 101 to connect the first capacitor core 2 and the power module 3, which is beneficial to shortening the lengths of the first connection assembly 4 and the second connection assembly 5, thereby reducing the stray inductance generated by the first capacitor core 2 and the power module 3.

[0092] In addition, since the first plate body 103 and the potting opening 102 are respectively located on both sides of the housing 1 in the first direction, in this way, when the electrical component module 1000 is assembled and the insulating filling material is poured into the housing 1 through the potting opening 102, the first connection assembly 4 and the second connection assembly 5 will not block the insulating filling material, which is beneficial to the flow of the insulating filling material in the housing 1, thereby improving the filling effect of the insulating filling material in the housing 1.

[0093] Optionally, as Figure 1 shown, the above-mentioned first direction can be the thickness direction of the housing 1, that is, the potting opening 102 and the first plate body 103 are opposite to each other in the thickness direction of the housing 1.

[0094] In addition, to cool the first capacitor core 2 and the power module 3, optionally, as Figure 1 , Figure 4 ,Figure 5 and Figure 7 As shown in Figure 7 , the above-mentioned housing 1 has a heat dissipation part 104, and the heat dissipation part 104 is used to cool the first capacitor core 2 and the power module 3. Since the heat dissipation part 104 can dissipate heat from the first capacitor core 2 and the power module 3, in this way, during the operation of the first capacitor core 2 and the power module 3, the first capacitor core 2 and the power module 3 can always operate within a suitable temperature range, thereby effectively avoiding damage to the first capacitor core 2 and the power module 3 and improving the service life of the first capacitor core 2 and the power module 3.

[0095] Moreover, since the first capacitor core 2 and the heat dissipation module are integrated in the housing 1 and cooled by the same heat dissipation part 104, in the electrical component module 1000 provided by the present disclosure, there is no need to set multiple different heat dissipation structures, and 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. Thus, it can effectively avoid the increase in the volume and structural complexity of the electrical component module 1000 caused by setting multiple different heat dissipation structures in the electrical component module 1000 to dissipate heat from the first capacitor core 2 and the power module 3.

[0096] In the electrical component module 1000 provided by the present disclosure, any appropriate positional relationship may exist among the first capacitor core 2, the power module 3, and the heat dissipation part 104. For example, the first capacitor core 2 and the power module 3 may be located on the same side of the heat dissipation part 104, or the first capacitor core 2 and the power module 3 may also be located on different sides of the heat dissipation part 104. The present disclosure does not limit this.

[0097] As an implementation manner of the present disclosure, as shown in Figure 1 , Figure 3 , Figure 5 and Figure 7 shown, the above-mentioned first capacitor core 2 and power module 3 are respectively located on opposite sides of the heat dissipation part 104. In other words, the first capacitor core 2 and the power module 3 are respectively located on different sides of the heat dissipation part 104, and the first capacitor core 2, the heat dissipation part 104, and the power module 3 form a "sandwich" structure. The first capacitor core 2, the power module 3, and the heat dissipation part 104 are compactly arranged, which is beneficial to improving the volume density and power density of the electrical component module 1000. At the same time, it can also reduce the volume of the heat dissipation part 104, thereby avoiding the increase in the volume and cost of the electrical component module 1000 caused by the over-large volume of the heat dissipation part 104.

[0098] It should be noted that the present 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 above-mentioned heat dissipation part 104 can be a fan, or the above-mentioned heat dissipation part 104 can also be a structure or material that can absorb heat, etc. The present disclosure does not limit this.

[0099] As one embodiment of the present disclosure, the heat dissipation portion 104 is provided with a first flow channel for a cooling medium to flow through, and the housing 1 is provided with a cooling medium inlet 105 and a cooling medium outlet 106 that communicate with the first flow channel. In this manner, 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, flow out of the cooling medium outlet 106. The flowing cooling medium provides a better heat dissipation effect, thereby improving the heat dissipation effect of the first capacitor core 2 and the power module 3.

[0100] Here, it should be noted that, in the electrical device module 1000 provided in the present disclosure, the above-mentioned 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 above-mentioned cooling medium can be a refrigerant, or the above-mentioned cooling medium can be a coolant, and the present disclosure does not limit this.

[0101] In order to further improve the heat dissipation effect of the heat dissipation portion 104 on the power module 3, optionally, as Figure 1 as well as Figures 5 to 7 As shown, the power module 3 may include heat dissipation pins 305, which are inserted into the first flow channel. Since the heat dissipation pins 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 pins 305, thereby dissipating heat from the power module 3. The heat dissipation pins 305, which are in direct contact with the cooling medium, can improve the heat dissipation effect of the heat dissipation unit 104 on the power module 3, thereby ensuring that the heat dissipation module operates within a reasonable temperature range.

[0102] In the electrical device module 1000 provided in the present disclosure, the heat dissipation portion 104 can be disposed at any appropriate location on the housing 1. For example, the heat dissipation portion 104 can be disposed inside the housing 1, or the heat dissipation portion 104 can be disposed outside the housing 1, or the heat dissipation portion 104 itself can be part of the housing 1, and the present disclosure does not limit this. For example, in an embodiment in which the power module 3 and the first capacitor core 2 are both disposed inside the housing 1, the heat dissipation portion 104 can be disposed inside the housing 1.

[0103] As an embodiment of the present disclosure, Figures 1 to 5 as well as Figure 7 As shown, the above-mentioned shell 1 includes a first plate body 103 and multiple second plates 107 surrounding the first plate body 103. The first plate body 103 and the second plate body 107 together form a accommodating cavity 108. The first capacitor core 2 is located in the accommodating cavity 108. The power module 3 is located on the side of the first plate body 103 away from the accommodating cavity 108 and is installed on the first plate body 103. The first plate body 103 has a heat dissipation portion 104.

[0104] Since the first capacitor core 2 is located on the side of the first plate 103 close to the accommodating cavity 108, the power module 3 is located on the side of the first plate 103 away from the accommodating cavity 108, and the heat dissipation portion 104 is a part of the first plate 103, that is, the first plate 103 can serve as a part of the shell 1 and together with the second plate 107 to form the accommodating cavity 108, and the first plate 103 has the heat dissipation portion 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.

[0105] In addition, since the first capacitor core 2 is located in the accommodating cavity 108 jointly surrounded by the first plate 103 and multiple second plates 107, the first plate 103 and 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.

[0106] For the embodiment in which the heat dissipation portion 104 includes the first flow channel and the heat dissipation portion 104 is part of the first plate 103, the present disclosure does not limit the specific method of forming the first flow channel on the first plate 103. As one embodiment of the present 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 groove 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.

[0107] As another embodiment of the present disclosure, the first flow channel may be directly formed in the first plate body 1031 .

[0108] In order to facilitate the power module 3 to always be in close contact with the heat dissipation portion 104, optionally, as Figure 5 and Figure 6 As shown, the electrical device module 1000 further includes a pressing block 6 and a threaded fastener 7. The heat dissipation portion 104 is provided with a threaded hole 1041. The pressing block 6 is used to press the power module 3 against the heat dissipation portion 104. The threaded fastener 7 can pass through the pressing block 6 and connect with the threaded hole 1041. In this manner, the pressing block 6 and the threaded fastener 7 secure the power module 3, effectively preventing it from shaking and affecting the normal operation of the electrical device module 1000. Furthermore, the pressing block 6 consistently presses the power module 3 against the heat dissipation portion 104, effectively ensuring the heat dissipation effect of the heat dissipation portion 104 on the power module 3.

[0109] Alternatively, as Figures 1 to 5 as well as Figure 7As shown, at least one second plate body 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 accommodation cavity 108, thereby cooling the devices in the accommodation cavity 108, such as the first capacitor core 2 or the fuse 22, relay 18, etc. mentioned below. In addition, the second flow channel can also dissipate heat from the devices arranged close to the second plate body 107 (such as the fuse 22, relay 18, etc. mentioned below).

[0110] As an implementation manner of the present disclosure, as Figures 1 to 5 and Figure 7 shown, the above-mentioned multiple second plate bodies 107 include a first side plate 1072 and a second side plate 1073. The above-mentioned electrical device module 1000 may further include a relay 18 and a fuse 22. The relay 18 and the fuse 22 are both arranged in the accommodation cavity 108 of the housing 1, and 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. Second flow channels are arranged 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 channels in the first side plate 1072 and the second side plate 1073 can cool the fuse 22.

[0111] The present disclosure does not limit the specific formation manner of the second flow channel on the second plate body 107. As an implementation manner of the present disclosure, the above-mentioned second plate body 107 may further 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 notch of the second flow channel groove, so as to jointly define the second flow channel with the groove wall of the second flow channel groove.

[0112] As other implementation manners of the present disclosure, the second flow channel may also be directly formed in the second plate body 107.

[0113] In the present disclosure, the above-mentioned housing 1 may be made of a metal material. On the one hand, the housing 1 made of a metal material has high strength and is not easily damaged, which is beneficial to improving the service life of the electrical device module 1000; on the other hand, the housing 1 made of a metal material has high thermal conductivity, which is beneficial to further improving the heat dissipation effect of each device (such as the first capacitor core 2 and the power module 3, etc.) in the electrical device module 1000; on the other hand, for the embodiment in which the above-mentioned heat dissipation part 104 is a part of the housing 1, the housing 1 made of a metal material can make the first capacitor core 2 and the power module 3 in thermal contact with the heat dissipation part 104.

[0114] In order to enable the above-mentioned electrical device module 1000 to be used under high-power conditions, optionally, as Figure 3 and Figures 13 to 17As shown, there are multiple first capacitor cores 2. The total equivalent capacitance of the multiple first capacitor cores 2 is relatively large, the voltage stabilization ability is relatively large, and the ripple voltage is relatively small. It can be used under working conditions with large current and large power, and is beneficial to improving the reliability of the entire circuit.

[0115] In addition, by reasonably designing the models of the multiple first capacitor cores 2, for example, setting multiple first capacitor cores 2 with larger capacitance values and multiple first capacitor cores 2 with smaller capacitance values, it is possible to filter out both low-frequency noise and high-frequency noise in the circuit, which is beneficial to enabling the electrical component module 1000 to be applicable to circuits with a wider frequency range.

[0116] To facilitate the connection of the multiple first capacitor cores 2, optionally, as Figure 8 and Figures 10 to 17 shown, the above-mentioned first connection component 4 includes a first busbar 401, 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 electrode 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 electrode 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 connect the positive or negative electrodes of the multiple first capacitor cores 2 at the same time and is connected to the input terminal of the first power module 3. The second busbar 501 can connect the negative or positive electrodes of the multiple first capacitor cores 2 at the same time and is connected to the input terminal of the second power module 3, so as to realize 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.

[0117] Here, it should be noted that the present disclosure does not limit the specific connection method between the first busbar 401 and the second busbar 501 and the positive or negative electrode of the first capacitor core 2. As the first implementation manner of the present disclosure, as Figure 8 and Figures 10 to 17 shown, the above-mentioned first busbar 401 can be connected to the positive electrode of the first capacitor core 2, and the second busbar 501 is connected to the negative electrode of the first capacitor core 2. Or, as the second implementation manner of the present disclosure, as Figure 10 and Figure 11 shown, the above-mentioned first busbar 401 can also be connected to the negative electrode of the first capacitor core 2, and the second busbar 501 is connected to the positive electrode of the first capacitor core 2.

[0118] Optionally, at least a part of the first bus bar 401 and at least a part of the second bus bar 501 are stacked. Since the current directions of the first bus bar 401 and the second bus bar 501 are opposite, stacking at least a part of the first bus bar 401 and at least a part of the second bus bar 501 can make the magnetic field directions generated by the first bus bar 401 and the second bus bar 501 due to the electromagnetic induction phenomenon opposite, and the magnetic field directions generated by the first bus bar 401 and the second bus bar 501 due to the electromagnetic induction phenomenon can cancel each other out, thereby reducing the stray inductance between the first capacitor core 2 and the power module 3.

[0119] Optionally, as Figure 8 and Figures 10 to 17 shown, the first bus bar 401 may include a first main body portion 402, a first extension portion 403, and a first connection portion 404, and the second bus bar 501 includes a second main body portion 502, a second extension portion 503, and a second connection portion 504. The first main body portion 402 and the second main body portion 502 are arranged at intervals in a first direction. The first capacitor core 2 is located between the first main body portion 402 and the second main body portion 502. One of the first main body portion 402 and the second main body portion 502 is connected to the positive electrodes of the plurality of first capacitor cores 2, and the other of the first main body portion 402 and the second main body portion 502 is connected to the negative electrodes of the plurality of first capacitor cores 2. The first connection portion 404 is used to connect to the input terminal of the first power module 3. The first extension portion 403 is connected between the first main body portion 402 and the first connection portion 404. The second connection portion 504 is used to connect to the input terminal of the second power module 3. The second extension portion 503 is connected between the second main body portion 502 and the second connection portion 504. In this way, only by connecting the first main body portion 402 and the second main body portion 502 to the positive and negative electrodes of the plurality of first capacitor cores 2 respectively, and connecting the first connection portion 404 and the second connection portion 504 to the input terminal of the first power module 3 and the input terminal of the second power module 3 respectively, the electrical connection between the plurality of first capacitor cores 2 and the power module 3 can be realized.

[0120] Optionally, the first extension portion 403 and the second extension portion 503 are located on the same side of the first main body portion 402 and the second main body portion 502. Since the first extension portion 403 and the second extension portion 503 are located on the same side of the first main body portion 402 and the second main body portion 502, the distance between the first connection portion 404 and the second connection portion 504 respectively arranged at one ends of the first extension portion 403 and the second extension portion 503 can be made relatively close, thereby facilitating the connection to the power module 3.

[0121] Here, it can be understood that for the embodiment where the first capacitor core 2 is arranged inside the housing 1 and the power module 3 is arranged outside the housing 1, the first main body portion 402 and the second main body portion 502 are located inside the housing 1, the first connection portion 404 and the second connection portion 504 are located outside the housing 1, and the first extension portion 403 and the second extension portion 503 can play the role of leading out and connecting, so that the first main body portion 402 and the first connection portion 404 of the first busbar 401 can be connected, and the second main body portion 502 and the second connection portion 504 of the second busbar 501 can be connected.

[0122] Optionally, as Figure 8 and Figures 10 to 17 shown, a first through hole 4021 can be formed on the first main body portion 402, a second through hole 5021 is formed on the second main body portion 502, and the first through hole 4021 and the second through hole 5021 can allow an insulating filling material to pass through. In this way, when the electrical component module 1000 is assembled and the insulating filling material is poured into the housing 1 through the pouring port 102, the insulating filling material can flow between the plurality of first capacitor cores 2 and into the gaps between the plurality of first capacitor cores 2 and the housing 1 through the first through hole 4021 and the second through hole 5021, so as to realize the insulation between the plurality of first capacitor cores 2 and between the plurality of first capacitor cores 2 and the housing 1, and the electrical component module 1000 has good insulation performance and is not prone to short - circuit and other phenomena.

[0123] In order to reduce the stray inductance between the first capacitor core 2 and the power module 3 and improve the anti - interference ability of the electrical component module 1000, optionally, as Figure 8 and Figures 10 to 17 shown, the first extension portion 403 of at least part of the first busbar 401 and the second extension portion 503 of at least part of the second busbar 501 are arranged in a stacked manner along the second direction (that is, the projection of the first extension portion 403 along the second direction and the projection of the second extension portion 503 along the second direction at least partially overlap), and the second direction intersects with the first direction.

[0124] Since the first extension portion 403 and the second extension portion 503 are stacked with each other or at least partially stacked with each other, and the current directions flowing through the first extension portion 403 and the second extension portion 503 are opposite, in this way, the magnetic field directions generated by the first extension portion 403 and the second extension portion 503 due to the electromagnetic induction phenomenon are opposite, and the magnetic field directions generated by the first extension portion 403 and the second extension portion 503 due to the electromagnetic induction phenomenon can cancel each other out, so as to reduce the stray inductance between the first capacitor core 2 and the power module 3.

[0125] As an implementation manner of the present disclosure, the first direction can be the thickness direction of the housing 1, and the second direction can be the length direction or the width direction of the housing 1.

[0126] Optionally, as Figures 10 to 12 , Figure 14 and Figure 16 and Figure 17 shown, the above-mentioned first connecting portion 404 extends from the first extending portion 403 in a direction away from the second extending portion 503, and the second connecting portion 504 extends from the second extending portion 503 in a direction away from the first extending portion 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 facing-away first connecting portion 404 and second connecting portion 504 do not occupy the space between the first extending portion 403 and the second extending portion 503, so that the distance between the first extending portion 403 and the second extending portion 503 can be shortened. The first extending portion 403 and the second extending portion 503 with a smaller distance can ensure that the magnetic fields generated by the first extending portion 403 and the second extending portion 503 cancel each other out, thereby reducing the stray inductance generated by the first extending portion 403 and the second extending portion 503.

[0127] As other embodiments of the present disclosure, the above-mentioned first connecting portion 404 and 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 the 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, in this way, the directions of the magnetic fields generated by the first connecting portion 404 and the second connecting portion 504 due to the electromagnetic induction phenomenon are opposite and can also cancel each other out, which is beneficial to further reducing the stray inductance between the first capacitor core 2 and the power module 3.

[0128] To avoid short-circuiting between the first busbar 401 and the second busbar 501, optionally, the above-mentioned electrical component module 1000 may further include a first insulating member 8, and the first insulating member 8 can insulate the first busbar 401 and the second busbar 501 from each other. Since the first insulating member 8 can insulate the first busbar 401 and the second busbar 501 from each other, it can avoid the situation that the first busbar 401 and the second busbar 501 are prone to short-circuiting due to the small distance between the first busbar 401 and the second busbar 501.

[0129] For example, the first insulating member 8 can insulate the first extending portion 403 of the first busbar 401 and the second extending portion 503 of the second busbar 501 from each other, so as to avoid the situation that the first extending portion 403 and the second extending portion 503 are prone to short-circuiting due to the small distance between the first extending portion 403 and the second extending portion 503.

[0130] The present 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 portion 403 and the second extension portion 503, or may be an insulating layer coated on the surfaces of the first extension portion 403 and the second extension portion 503.

[0131] As an embodiment of the present disclosure, as Figure 12 and Figure 17 shown, the first insulating member 8 includes a wrapping portion 801 and a first electricity isolation portion disposed within the wrapping portion 801. At least a part of the first extension portion 403 and at least a part of the second extension portion 503 are wrapped within the wrapping portion 801, and the first electricity isolation portion is located between the first extension portion 403 and the second extension portion 503. The first electricity isolation portion can achieve insulation between the first extension portion 403 and the second extension portion 503, thereby avoiding a short circuit between the first extension portion 403 and the second extension portion 503.

[0132] In addition, since at least a part of the first extension portion 403 and at least a part of the second extension portion 503 can be wrapped within the wrapping portion 801, on the one hand, the first insulating member 8 can insulate the first bus bar 401 and the second bus bar 501, avoiding a short circuit between the first bus bar 401 and the second bus bar 501; on the other hand, the first insulating member 8 can also connect and fix the first bus bar 401 and the second bus bar 501. After the first insulating member 8 is disposed on the first extension portion 403 and the second extension portion 503, the first bus bar 401 and the second bus bar 501 connected by the first insulating member 8 can form an integral body, facilitating connection to the first core unit, and the assembly between the first bus bar 401, the second bus bar 501 and the first core unit is relatively simple.

[0133] In addition, the wrapping portion 801 can also prevent the first extension portion 403 and the second extension portion 503 from contacting other components within the motor controller, thereby insulating the first extension portion 403 and the second extension portion 503 from other components within the motor controller (such as the housing 1 made of a metal material), further improving the lifespan of the electrical component module 1000 and the motor controller applying the electrical component module 1000.

[0134] Optionally, the first insulating member 8 may be formed on the first extension portion 403 and the second extension portion 503 through an injection molding process. The injection-molded first insulating member 8 does not require separate installation and can be formed on the first extension portion 403 and the second extension portion 503 with just one injection, which is beneficial to simplifying the assembly process of the first bus bar 401 and the second bus bar 501 on the electrical component module 1000.

[0135] Optionally, as Figure 1 、 Figure 7 、Figure 12 , Figure 14 Figure 16 and Figure 17 As shown, the above-mentioned first capacitor core 2, first main body portion 402, and second main body portion 502 are located inside the housing 1, the power module 3, first connection portion 404, and second connection portion 504 are located outside the housing 1, a first opening 101 is formed on the housing 1, the first extension portion 403 and the second extension portion 503 pass through the first opening 101, and the wrapping portion 801 is configured to be able to block the gap between the first extension portion 403 and the first opening 101 and the gap between the second extension portion 503 and the first opening 101.

[0136] Since the wrapping portion 801 is configured to be able to block the gaps between the first extension portion 403 and the second extension portion 503 and the first opening 101, in this way, the first insulating member 8 can not only achieve insulation between the first extension portion 403 and the second extension portion 503, but also achieve insulation between the first extension portion 403 and the second extension portion 503 and the housing 1. In addition, it can also play a role in sealing the first opening 101. In this way, on the one hand, during use, dust and other impurities are not easily introduced into the interior of the housing 1 through the first opening 101, which is beneficial to ensuring the normal use of the electrical component module 1000; on the other hand, when pouring the insulating filling material into the housing 1 through the pouring opening 102 on the housing 1, the wrapping portion 801 can block the insulating filling material, effectively avoiding the leakage of the insulating filling material from the first opening 101 and affecting the insulation effect of the components arranged in the housing 1.

[0137] To ensure a good insulation effect between the first bus bar 401 and the second bus bar 501, optionally, as Figure 12 , Figure 14 and Figure 16 and Figure 17 As shown, the above-mentioned first insulating member 8 further includes a second electricity isolating portion 802, the second electricity isolating portion 802 is located between the first connection portion 404 and the second connection portion 504, and the second electricity isolating portion 802 protrudes from the first connection portion 404 and the second connection portion 504 in a direction away from the first extension portion 403 and the second extension portion 503. The second electricity isolating portion 802 protruding from the first connection portion 404 and the second connection portion 504 in a direction away from the first extension portion 403 and the second extension portion 503 can provide creepage insulation for the first connection portion 404 and the second connection portion 504, effectively avoiding the situation that due to the relatively short distance between the first connection portion 404 and the second connection portion 504, the first connection portion 404 and the second connection portion 504 are prone to arc creepage, high-voltage arcing, or even short circuit, and further improving the insulation effect between the first bus bar 401 and the second bus bar 501.

[0138] Optionally, the above-mentioned first connecting portion 404 may protrude from the first extending portion 403 along the second direction, the second connecting portion 504 may protrude from the second extending portion 503 along the second direction, and the first connecting portion 404 and the second connecting portion 504 are arranged side by side and away from 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 first connecting portion 404 and the second connecting portion 504 arranged away from each other and the power module 3 is relatively convenient, and insulation can be achieved through the second insulating portion 802.

[0139] The present disclosure does not limit the specific structure of the first extending portion 403 either. In order to reduce the stray inductance generated by the first extending portion 403 on the premise of facilitating the connection with the first capacitor core 2, optionally, as Figure 8 , Figure 10 and Figure 11 shown, the above-mentioned first extending portion 403 or the second extending portion 503 includes a first part 4031 and a second part 4032. For example, as Figure 10 shown, when at least part of the first busbar 401 is located below the second busbar 501, the first extending portion 403 includes a first part 4031 and a second part 4032, and as Figure 11 shown, when at least part of the second busbar 501 is located below the first busbar 401, the second extending portion 503 may include a first part 4031 and a second part 4032. Among them, the first part 4031 is located on the side of a part of the first capacitor cores 2 among the plurality of first capacitor cores 2, and the second part 4032 is located on the side of another part of the first capacitor cores 2 among the plurality of first capacitor cores 2. The first part 4031 protrudes from the second part 4032 in a direction away from the first capacitor core 2. Both the first part 4031 and the second part 4032 can play a role in limiting the first capacitor core 2 inside them, effectively avoiding the situation that when connecting the first capacitor core 2 and the first busbar 401, the first capacitor core 2 moves, affecting the connection between the first capacitor core 2 and the first busbar 401.

[0140] In addition, for the implementation modes in which the models and sizes of the plurality of first capacitor cores 2 are different, by reasonably designing the positional relationship between the first part 4031 and the second part 4032 in the above manner, the distance between the two parts (i.e., the first part 4031 and the second part 4032) of the first extending portion 403 and the plurality of first capacitor cores 2 can be shortened, so that the length of the loop connecting the first capacitor core 2 and the power module 3 can be shortened. A shorter length has a lower stray inductance, which is beneficial to further reducing the stray inductance between the first capacitor core 2 and the power module 3.

[0141] Optionally, as Figure 10 and Figure 13As described above, a third through hole 4033 is formed in the first portion 4031 of the first extension portion 403. In this way, when the electrical component module 1000 is assembled and the insulating filling material is poured into the housing 1 through the pouring port 102, the insulating filling material can flow through the third through hole 4033 to the plurality of first capacitor cores 2 and between the plurality of first capacitor cores 2 and the first extension portion 403, so as to achieve insulation between the plurality of first capacitor cores 2 and between the plurality of first capacitor cores 2 and the first extension portion 403. The electrical component module 1000 has good insulation performance and is not prone to short - circuit and other phenomena.

[0142] To facilitate the connection of the first bus bar 401 and the second bus bar 501 to the power module 3, optionally, as Figure 1 ,, Figure 2 and Figure 19 shown, the first connection component 4 further includes a first connecting member 405, the second connection component 5 further includes a second connecting member 505. One end of the first connecting member 405 is connected to the first bus bar 401, and the other end of the first connecting member 405 is connected to the input terminal of the first power module 3. One end of the second connecting member 505 is connected to the second bus bar 501, and the other end of the first connecting member 405 is connected to the input terminal of the second power module 3. The first connecting member 405 and the second connecting member 505 can respectively realize the electrical connection between the first bus bar 401 and the second bus bar 501 and the power module 3, so as to connect the first capacitor core 2 to the power module 3.

[0143] For the embodiment in which the first insulating member 8 includes the wrapping portion 801, in order to avoid the displacement of the first connecting member 405 and / or the second connecting member 505 during connection, optionally, as Figure 14 shown, a positioning post 8011 is provided on the wrapping portion 801, and positioning holes 506 are formed in the first electrical connecting member and the second electrical connecting member. In this way, when the first connecting member 405 is connected to the first bus bar 401 or the power module 3, and when the second connecting member 505 is connected to the second bus bar 501 or the power module 3, the positioning post 8011 and the positioning holes 506 cooperate with each other to realize the positioning of the first connecting member 405 and the second connecting member 505. The first connecting member 405 and the second connecting member 505 are not prone to displacement, and the connection between the first connecting member 405 and the first bus bar 401 or the power module 3 and the connection between the second connecting member 505 and the second bus bar 501 or the power module 3 are reliable.

[0144] To further reduce the stray inductance between the first capacitor core 2 and the power module 3, optionally, as Figure 1 and Figure 2 shown, at least part of the first connecting member 405 and at least part of the second connecting member 505 are stacked along the first direction.

[0145] Here, it should be noted first that the above-mentioned at least partial first connecting member 405 and at least partial second electrical connecting member being stacked in the first direction means that the projection of the first connecting member 405 in the first direction and the projection of the second electrical connecting member in the first direction at least partially overlap.

[0146] Since the projection of the first connecting member 405 and the projection of the second electrical connecting member at least partially overlap, and the current directions flowing through the first connecting member 405 and the second electrical connecting member are opposite, in this way, the magnetic field directions generated by the first connecting member 405 and the second electrical connecting member due to the electromagnetic induction phenomenon are opposite, and the magnetic fields generated by the first connecting member 405 and the second electrical connecting member due to the electromagnetic induction phenomenon can cancel each other out, thereby further reducing the stray inductance between the first connecting member 405 and the second electrical connecting member.

[0147] Optionally, as Figure 8 and Figure 19 shown, the first bus bar 401 has a first connecting portion 404, the second bus bar 501 has a second connecting portion 504, the first connecting portion 404 and the second connecting portion 504 are arranged side by side in the second direction, the second direction intersects the first direction, the first connecting member 405 includes a first overlapping portion 407, a conducting portion 408, and a first capacitor output terminal 409, the conducting 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, the first capacitor output terminal 409 overlaps with the input terminal of the first power module 3, the second connecting member 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, the second capacitor output terminal 508 overlaps with the input terminal of the second power module 3, and at least part of the conducting portion 408 and at least part of the second overlapping portion 507 are stacked in the first direction.

[0148] In this way, only by connecting the first overlapping portion 407 and the first capacitor output terminal 409 to the first connecting portion 404 and the input terminal of the first power module 3 respectively, and connecting the second overlapping portion 507 and the second capacitor output terminal 508 to the second connecting portion 504 and the input terminal of the second power module 3 respectively, the electrical connection between the first bus bar 401 and the first connecting member 405 and between the second bus bar 501 and the second connecting member 505 can be realized.

[0149] In addition, 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 input terminal of the first power module 3, and the second capacitor output terminal 508 and the input terminal of the second power module 3 are all overlapped with each other. In this way, on the one hand, the contact areas between the mutually overlapped 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 input terminal of the first power module 3, and the second capacitor output terminal 508 and the input terminal of the second power module 3 are relatively large, and can conduct a relatively large current and have a relatively large power. On the other hand, the mutually overlapped 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 input terminal of the first power module 3, and the second capacitor output terminal 508 and the input terminal of the second power module 3 can be connected by fusion processes such as laser welding or processes such as press riveting, and the connection is relatively convenient.

[0150] For the embodiment in which the first insulating member 8 includes the second electricity isolating portion 802, and the second electricity isolating portion 802 protrudes from the first connecting portion 404 and the second connecting portion 504 in a direction away from the first extending portion 403 and the second extending portion 503, in order to avoid the second electricity isolating portion 802, optionally, as Figure 19 shown, the above-mentioned first connecting member 405 may further include an avoiding portion 410. One end of the avoiding portion 410 is connected to the first overlapping portion 407, the other end of the avoiding portion 410 is connected to the conducting portion 408, and the avoiding portion 410 is bent into a U shape in a direction away from the first extending portion 403 and the second extending portion 503. The U-shaped avoiding portion 410 will not interfere with the second electricity isolating portion 802, so that the connection between the power module 3 and the first connecting portion 404 can be realized.

[0151] Optionally, the above-mentioned power module 3 may include a plurality of input terminals of the first power module 3 and a plurality of input terminals of the second power module 3. The plurality of input terminals of the first power module 3 and the plurality of input terminals of the second power module 3 are arranged at intervals along a third direction. The third direction intersects with the above-mentioned first direction and the second direction. The first connecting member 405 includes a plurality of first capacitor output terminals 409, and the plurality of first capacitor output terminals 409 are arranged in one-to-one correspondence with the plurality of input terminals of the first power module 3. The second connecting member 505 includes a plurality of second capacitor output terminals 508, and the plurality of second capacitor output terminals 508 are arranged in one-to-one correspondence with the plurality of input terminals of the second power module 3.

[0152] In order to insulate the first connecting member 405 and the second connecting member 505, optionally, as Figure 1 and Figure 21As shown, the above-mentioned electrical component module 1000 further includes a second insulating member 23. The second insulating member 23 includes a first insulating portion 231 and a second insulating portion 232. The first insulating portion 231 is located between the conducting portion 408 and the second overlapping portion 507, and the second insulating portion 232 is located between the first capacitor output terminal 409 and the input terminal of the first power module 3 and the second capacitor output terminal 508 and the input terminal of the second power module 3.

[0153] In this way, the first insulating portion 231 can achieve insulation between the first connecting member 405 and the second connecting member 505, effectively avoiding short circuits between the first connecting member 405 and the second connecting member 505, which may 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.

[0154] In addition, since the second insulating portion 232 is located between the first capacitor output terminal 409 and the input terminal of the first power module 3 and the second capacitor output terminal 508 and the input terminal of the second power module 3, the second insulating portion 232 can achieve insulation between multiple capacitor output terminals and multiple input terminals of the power module 3. It is not easy to have short circuits between the first connecting member 405 and the second connecting member 505, and between multiple input terminals of the power module 3.

[0155] To improve the practicality of the electrical component module 1000, optionally, as Figures 13 to 17 shown, the above-mentioned electrical component module 1000 further includes a second capacitor core 9 and a third connection assembly 10. The second capacitor core 9 is installed in the housing 1 and is adjacent to the first capacitor core 2. The third connection assembly 10 is connected to the positive electrode of the second capacitor core 9, and one of the first busbar 401 and the second busbar 501 is connected to the negative electrodes of the first capacitor core 2 and the second capacitor core 9.

[0156] The second capacitor core 9 and the first capacitor core 2 cooperate with each other, enabling the electrical component module 1000 to have different operating conditions. For example, one of the first capacitor core 2 and the second capacitor core 9 is connected to an external load, and the other of the first capacitor core 2 and the second capacitor core 9 is disconnected from the external load, or both the first capacitor core 2 and the second capacitor core 9 are connected to the external load. In this way, the practicality of the electrical component module 1000 can be improved.

[0157] In the present disclosure, the first capacitor core 2 and the second capacitor core 9 can have any suitable type. For example, both the first capacitor core 2 and the second capacitor core 9 can be drive capacitor cores. The first capacitor core 2 and the second capacitor core 9 cooperate with each other, which can increase the overall capacitance of the electrical component module 1000 and enable the electrical component module 1000 to have better voltage stability.

[0158] As an implementation manner of the present disclosure, the above-mentioned first capacitor core 2 is a driving capacitor core, and the second capacitor core 9 is a boost capacitor core. The driving capacitor core and the boost capacitor core cooperate with each other to meet the usage requirements of the electrical component module 1000 under high-voltage and low-voltage working conditions. For example, when the motor controller applying the electrical component module 1000 is applied to a vehicle, by disconnecting or turning off the boost capacitor from the external load, the vehicle can have two working modes: slow charging and fast charging.

[0159] To facilitate the connection between the electrical component module 1000 and the external load, optionally, as Figure 1 , Figure 7 , Figure 12 , Figure 14 , Figure 16 and Figure 17 shown, the above-mentioned 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 arranged on the housing 1. Among the first busbar 401 and the second busbar 501, the one connected to the positive electrode of the first capacitor core 2 is the positive busbar, and the one connected to the negative electrode of the first capacitor core 2 is the negative busbar. 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. Through the first external terminal 11, the second external terminal 12, and the third external terminal 13, the connection between the first capacitor core 2 and the second capacitor core 9 and the external load can be realized, and the connection between the first capacitor core 2 and the second capacitor core 9 and the external load (such as a battery pack) is relatively convenient.

[0160] Optionally, as Figure 1 , Figure 7 , Figure 12 , Figure 14 , Figure 16 and Figure 17 shown, the above-mentioned first external terminal 11, second external terminal 12, and third external terminal 13 are all arranged on the same side of the housing 1 and are spaced along the third direction. In this way, by reasonably designing the specific positions of the above-mentioned 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 above-mentioned multiple terminals and the output connectors of the external load can be mutually adapted. Thus, the length of the electrical connection row 21 between the above-mentioned multiple terminals and the output connectors of the external load can be shortened, thereby simplifying the connection complexity between the electrical component module 1000 and the external load.

[0161] The present disclosure does not limit the specific connection manner between the first external terminal 11 and the positive busbar. As the first implementation manner of the present disclosure, as Figure 10As shown, the above-mentioned first busbar 401 is a positive busbar, and the second busbar 501 is a negative busbar. The first extension portion 403 of the first busbar 401 is disposed on the side of the second extension portion 503 of the second busbar 501 closer to the first external terminal 11. The electrical component module 1000 may further include a first intermediate connection bar 14. One end of the first intermediate connection bar 14 is connected to the positive busbar, that is, the first busbar 401, and the other end of the first intermediate connection bar 14 is connected to the first external terminal 11. Thus, through the first intermediate connection bar 14, the connection between the first external terminal 11 and the positive busbar can be achieved.

[0162] As a second implementation manner of the present disclosure, as Figure 11 shown, the above-mentioned first busbar 401 is a negative busbar, and the second busbar 501 is a positive busbar. The first extension portion 403 of the first busbar 401 is disposed on the side of the second extension portion 503 of the second busbar 501 closer to the first external terminal 11. A through hole 5031 is formed in the first extension portion 403. The electrical component module 1000 may further include a first intermediate connection bar 14. One end of the first intermediate connection bar 14 can pass through the through hole 5031 and be connected to the positive busbar, that is, the second busbar 501, and the other end of the first intermediate connection bar 14 is connected to the first external terminal 11. Since the first intermediate connection bar 14 can pass through the through hole 5031 and be connected to the positive busbar, thus, the connection between the first external terminal 11 and the positive busbar can be achieved without increasing the length of the first intermediate connection bar 14, effectively avoiding the situation where the length of the first intermediate connection bar 14 increases because the first intermediate connection bar 14 needs to bypass one side of the negative busbar and be connected to the positive busbar.

[0163] The present disclosure does not limit the connection relationship between the third external terminal 13 and the negative busbar either. As a first implementation manner of the present disclosure, the above-mentioned first busbar 401 is a positive busbar, and the second busbar 501 is a 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 connection bar 15. One end of the second busbar 501, that is, the negative busbar, is bent in the third direction to form an external connection portion 4011. 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 external connection portion 4011. Thus, through the fourth intermediate connection bar 15, the electrical connection between the third external terminal 13 and the negative busbar can be achieved.

[0164] As another embodiment of the present disclosure, the above-mentioned first busbar 401 is a negative busbar, 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, and the electrical component module 1000 may further include a fourth intermediate connection row 15. One end of the fourth intermediate connection row 15 is connected to the third external terminal 13, and the other end of the fourth intermediate connection row 15 is connected to the side of the first busbar 401 close to the third external terminal 13.

[0165] The present disclosure does not limit the specific structure of the third connection component 10. Optionally, as Figure 12 and Figure 13 shown, the third connection component 10 includes a second intermediate connection row 111 and a third intermediate connection row 112. One end of the second intermediate connection row 111 is connected to the second external terminal 12, the other end of the second intermediate connection row 111 is connected to the third intermediate connection row 112, and the third intermediate connection row 112 is connected to the positive electrode of the second capacitor core 9. In this way, through the second intermediate connection row 111 and the third intermediate connection row 112, the electrical connection between the positive electrode of the second capacitor core 9 and the second external terminal 12 can be realized.

[0166] In order to further reduce the stray inductance of the electrical component module 1000, optionally, as Figure 12 shown, the above-mentioned second intermediate connection row 111 is bent into a "Z" shape. The "Z" - shaped second intermediate connection row 111 can not only realize the connection between the second external terminal 12 and the third intermediate connection row 112, but also 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 is beneficial to reducing the stray inductance of the first busbar 401 and the second busbar 501, and further reducing the stray inductance of the electrical component module 1000.

[0167] In order 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 Figure 1 、 Figure 4 、 Figure 5 and Figure 7 shown, the above-mentioned 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 at least partially located outside the housing 1.

[0168] The electrical component module 1000 further 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 block 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 block the gap between the third external terminal 13 and the third opening 110. Since 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 relatively good, and it is not easy to occur short-circuit and other phenomena. In addition, 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 the insulating filling material is poured into the housing 1 through the pouring port 102, the third insulating member 16 and the fourth insulating member 17 can also play a role in blocking the insulating filling material, which can improve the filling effect of the insulating filling material in the housing 1.

[0169] Optionally, the above-mentioned third insulating member 16 is formed on the first external terminal 11 and the second external terminal 12 through an injection molding process, and / or the above-mentioned fourth insulating member 17 is formed on the third external terminal 13 through an injection molding process. The injection-molded third insulating member 16 and fourth insulating member 17 do not need to be installed separately, and can be formed on the first external terminal 11 and the second external terminal 12 or the third external terminal 13 only by one injection molding, which is beneficial to simplifying the assembly process of the first bus bar 401 and the second bus bar 501 on the electrical component module 1000.

[0170] To achieve the switching of different working conditions of the electrical component module 1000, optionally, as Figure 13 and Figure 15 shown, the above-mentioned electrical component module 1000 further includes a relay 18. The relay 18 is arranged inside the housing 1, and the relay 18 is connected to the first external terminal 11 and the second external terminal 12. In this way, by controlling the opening and closing of the relay 18, the conduction or disconnection between the first capacitor core 2 and the second capacitor core 9 can be achieved, so that the electrical component module 1000 can have different working conditions.

[0171] To facilitate the control of the relay 18, optionally, as Figure 18As shown, the above-mentioned relay 18 further includes a control pin 183, and the control pin 183 is adapted to be connected to the control board of the motor controller, so as to be able to control the working state of the relay 18, and further be able to control the conduction or disconnection between the first capacitor core 2 and the second capacitor core 9.

[0172] Optionally, the relay 18 can be arranged inside the housing 1, and the above-mentioned control pin 183 can pass through the housing 1 to facilitate connection to the control board of the motor controller.

[0173] Optionally, as Figure 1 , Figure 7 and Figures 12 to 17 shown, the above-mentioned electrical component module 1000 may further include a fourth external terminal 19, a fifth external terminal 20 and a connection row 21. The fourth external terminal 19 and the fifth external terminal 20 are arranged on the housing 1. One end of the connection row 21 is connected to the fourth external terminal 19, and the other end of the connection row 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, etc.) in the motor controller can be connected to the electrical component module 1000, so that the electrical component module 1000 can have multiple functions, and the practicality of the electrical component module 1000 is relatively strong.

[0174] Optionally, the above-mentioned fourth external terminal 19, the first external terminal 11, the second external terminal 12 and the third external terminal 13 are located on the same side of the housing 1, and the fifth external terminal 20 is arranged opposite to the fourth external terminal 19.

[0175] Optionally, the fourth external terminal 19 can pass through the above-mentioned second opening 109, and the fifth external terminal 20 can pass through a fourth opening 114 on the housing 1. The electrical component module 1000 may further 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 be able to block the gap between the fourth external terminal 19 and the second opening 109, and the sixth insulating member 25 is configured to be able to block the gap between the fifth external terminal 20 and the fourth opening 114.
