For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] Reference below Figure 1-Figure 13 A motor controller 100 according to an embodiment of the present invention is described.

[0064] like Figure 1-Figure 12As shown, the motor controller 100 according to the embodiment of the present invention includes: a box 10, a capacitor component 20, a power component 30, a three-phase component 40 and a control board 50, the capacitor component 20, the power component 30 and the three-phase component 40 can be respectively arranged in the box 10, and the capacitor component 20, the power component 30 and the three-phase component 40 can be arranged in a first direction (such as Figure 2 left and right direction as shown).

[0065] Alternatively, the power component 30 and the three-phase component 40 can be arranged along the first direction, and the power component 30 can be arranged in a staggered manner with the capacitor component 20; alternatively, the power component 30 and the three-phase component 40 can be arranged along the first direction, and the three-phase component 40 can be arranged in a staggered manner with the capacitor component 20; alternatively, the power component 30 and the three-phase component 40 can be arranged along the first direction, and the power component 30 and the three-phase component 40 can be arranged in a staggered manner with the capacitor component 20, respectively; that is, the capacitor component 20, the power component 30 and the three-phase component 40 can be located on the same plane, which is beneficial to reducing the thickness of the motor controller 100 and facilitating assembly.

[0066] The control board 50 may be disposed in the housing 10, and the control board 50 may be located at the second direction (eg Figure 5 In the up and down direction shown) on one side (such as Figure 5 The upper side shown in the figure) can reduce the thickness of the motor controller 100 in the second direction. For example, the thickness of the motor controller 100 in the second direction can be 65 mm, thereby realizing a flat design of the motor controller 100, reducing the volume of the motor controller 100, and facilitating layout.

[0067] The second direction and the first direction may intersect, for example, the second direction may be perpendicular to the first direction (eg Figure 5 The left and right directions shown in the figure are beneficial to the automated assembly of the motor controller 100 and can reduce the cost.

[0068] According to the motor controller 100 of the embodiment of the present invention, the power component 30 and the three-phase component 40 and / or the capacitor component 20 are arranged along a first direction, and the control board 50 is located on one side of the power component 30 in a second direction, and the second direction intersects with the first direction. The thickness of the motor controller 100 can be reduced, making the appearance of the motor controller 100 flatter, and the volume and weight of the motor controller 100 can be reduced, thereby improving the power density of the motor controller 100, improving the practicality of the motor controller 100, reducing the occupied space inside the car, and improving the space utilization rate of the entire vehicle.

[0069] like Figure 5 and Fig.11As shown, according to some embodiments of the present invention, the motor controller 100 may further include a low-voltage connector 70, which may be disposed on the control board 50, and the low-voltage connector 70 may be located at the control board 50 in the second direction (eg Figure 5 The low voltage connector 70 is located on one side of the control board 50 close to the power component 30 (as shown in the upper and lower directions). Figure 5 lower side shown).

[0070] Thus, the low-voltage connector 70 can be integrated on the control board 50. Compared with the solution in which the low-voltage connector 70 is horizontally installed on the side wall of the box body 10, the low-voltage connector 70 can be installed together with the control board 50 in the box body 10, thereby reducing the installation space reserved for the control board 50 and improving the space utilization of the motor controller 100. It can be understood that the low-voltage connector 70 can be welded to the control board 50, and the control board 50 and the low-voltage connector can be connected through pins for signal transmission.

[0071] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, according to some embodiments of the present invention, the motor controller 100 may further include a ventilation valve 90, which can protect the components within the motor controller 100 from moisture and dust, while ensuring normal ventilation of the motor controller 100 to maintain its stable operation, which is beneficial to improving the efficiency and performance of the motor controller 100.

[0072] like Figure 5 As shown, in some examples, a baffle 111 can be provided in the box body 10, and the baffle 111 can separate the box body 10 into a first accommodating chamber 1111, and the first accommodating chamber 1111 can accommodate the low-voltage connector 70, thereby improving the protection effect of the low-voltage connector 70, and improving the ability of the low-voltage connector 70 to resist electromagnetic interference, that is, preventing the low-voltage connector 70 from being interfered with by high voltage, and can improve the working stability of the low-voltage connector 70, and can improve the electromagnetic compatibility (EMC) of the motor controller 100.

[0073] like Figure 5 , Figure 8 and Fig. 9As shown, according to some embodiments of the present invention, the capacitor assembly 20 may include a seat body 21, a magnetic ring 22 and a capacitor core 23. The seat body 21 may have a first partition chamber 211 and a second partition chamber 212. The magnetic ring 22 may be arranged in the first partition chamber 211. The magnetic ring 22 may filter out noise signals in the circuit of the motor controller 100, thereby improving the working stability of the motor controller 100. The capacitor core 23 may be arranged in the second partition chamber 212, that is, the magnetic ring 22 is arranged separately from the capacitor, which can separate the heat source of the capacitor assembly 20, increase the heat dissipation surface of the capacitor assembly 20, and improve the heat dissipation effect of the capacitor assembly 20.

[0074] like Figure 5 , Figure 8 and Fig. 9 As shown, in some examples, the first partition chamber 211 and the second partition chamber 212 can be arranged along a third direction (eg Figure 8 The third direction may intersect with the first direction and the second direction. For example, the third direction (such as Figure 5 The front and rear directions shown in FIG. 1 and FIG. 2 may be respectively perpendicular to the first direction (such as Figure 5 The left and right directions shown) and the second direction (as shown Figure 5 , i.e., the length direction of the capacitor assembly 20 (as shown in the vertical direction). Figure 5 The front-to-back direction shown in FIG. 1 is perpendicular to the arrangement direction of the capacitor assembly 20, the power assembly 30 and the three-phase assembly 40 (as shown in FIG. Figure 5 The length direction of the capacitor assembly 20 is perpendicular to the installation direction of the control board 50 (as shown in the left and right direction). Figure 5 The up and down directions shown in the figure) can improve the space utilization of the motor controller 100.

[0075] like Figure 5 , Figure 8 and Fig. 9 As shown, in some examples, the first partition cavity 211 and the second partition cavity 212 are spaced apart in a second direction (eg Figure 5 The depth in the up and down directions (as shown) can be different. Therefore, by setting the magnetic ring 22 in the first partition cavity 211 and by setting the capacitor core 23 in the second partition cavity 212, a separate cavity design of the magnetic ring 22 and the capacitor core 23 can be achieved. Compared with setting the magnetic ring 22 and the capacitor core 23 in one cavity, the first partition cavity 211 and the second partition cavity 212 can be separately filled with glue, thereby reducing the amount of glue filling for the capacitor assembly 20 and reducing costs.

[0076] like Figure 5 , Figure 8 and Fig. 9As shown, in some examples, the seat body 21 can have a first support seat 213, the box body 10 can have a first opening 112, the first opening 112 can correspond to the position of the first support seat 213, and the motor controller 100 can also include a DC bus connector 80, the DC bus connector 80 can be arranged at the first opening 112, and the DC bus connector 80 can be installed on the first support seat 213 through the first opening 112, which is convenient for loading and unloading. On the one hand, the DC bus connector 80 can be supported and the connection effect between the DC bus connector 80 and the capacitor assembly 20 can be improved. On the other hand, the DC bus connector 80 can be horizontally installed on the motor controller 100, which can reduce the thickness of the motor controller 100.

[0077] like Figure 5 As shown, in some examples, after the control panel 50 is installed, the low-voltage connector 70 can be located at the third direction (such as Figure 5 The front-to-back direction shown) on one side (such as Figure 5 The low voltage connector 70 may be located at the DC bus connector 80 in the first direction (eg, Figure 5 side (as shown in the left and right directions) Figure 5 As shown on the right side, the multiple components in the motor controller 100 are dispersedly arranged on a plane, which can prevent the multiple components from interfering with each other during installation and facilitate assembly. At the same time, the thickness of the motor controller 100 can be reduced, the flat design of the motor controller 100 can be realized, and the volume of the motor controller 100 can be reduced.

[0078] like Figure 5 and Figure 8 As shown, in some examples, the first support seat 213 can be located at the seat body 21 in the third direction (such as Figure 8 The front-to-back direction shown) on one side (such as Figure 8 The third direction intersects the first direction and the second direction, for example, the third direction (as shown in FIG. Figure 5 The front and rear directions shown in FIG. 1 and FIG. 2 may be respectively perpendicular to the first direction (such as Figure 5 The left and right directions shown) and the second direction (as shown Figure 5 The first support base 213 can ensure that the first support base 213 supports the DC bus connector 80, and can prevent the first support base 213 and multiple components in the motor controller 100 from interfering with each other during installation.

[0079] like Figure 8 and Fig. 9As shown, in some examples, the seat body 21 may have a second support seat 214, and the power component 30 may be installed on the second support seat 214, which can support the power component 30 and improve the connection effect between the power component 30 and the capacitor component 20, and the second support seat 214 may be located on the seat body 21 in the first direction (such as Figure 8 side (as shown in the left and right directions) Figure 8 The right side as shown in the figure) is conducive to the position correspondence between the second support seat 214 and the power component 30, which facilitates the assembly of the power component 30.

[0080] like Figure 8 and Fig. 9 As shown, in some examples, the first support seat 213 and the second support seat 214 can be respectively integrated into the seat body 21 of the capacitor assembly 20, so that the first support seat 213 and the second support seat 214 can be installed in the box body 10 together with the seat body 21, which can reduce the number of components in the motor controller 100 and the number of assemblies, and at the same time, it is beneficial to improve the automated production speed of the motor controller 100 and reduce costs.

[0081] like Figure 5 , Figure 8 and Fig. 9 As shown, in some examples, the capacitor assembly 20 can also include a first safety capacitor 24 (Y capacitor) and a second safety capacitor 25 (Y capacitor). The first safety capacitor 24 can be arranged in the first partition chamber 211, and the second safety capacitor 25 can be arranged in the second partition chamber 212. The first safety capacitor 24 cooperates with the second safety capacitor 25 to suppress common-mode interference in the circuit of the motor controller 100, realize filtering of the circuit, and improve the stability and safety of the operation of the motor controller 100.

[0082] The first safety capacitor 24 is connected to the base 21 by filling the first partition chamber 211 with glue, and the second safety capacitor 25 is connected to the base 21 by filling the second partition chamber 212 with glue, which is convenient for operation. The first partition chamber 211 and the second partition chamber 212 have an open side (such as Figure 5 As shown in the figure, that is, the glue-filled surface of the capacitor assembly 20 faces upward, so that the first safety capacitor 24 and the second safety capacitor 25 can be grounded at high voltage by using the nearest grounding method, which can shorten the grounding path and improve the filtering effect of the circuit, while facilitating the adjustment of the parameters of the internal components of the capacitor assembly 20.

[0083] It should be noted that the capacitor assembly 20 may also include a positive busbar 26 and a negative busbar 27, the positive busbar 26 and the negative busbar 27 respectively pass through the magnetic ring 22 and are connected to the capacitor core 23, that is, the extension direction of the positive busbar 26 and the negative busbar 27 (such as Fig. 9The front-to-back direction (as shown) is consistent with the extension direction of the capacitor assembly 20, which is beneficial to reducing the thickness of the motor controller 100.

[0084] Specifically, one end of the positive busbar 26 and the negative busbar 27 (such as Fig. 9 The front end shown in FIG. 2 extends to the first support seat 213, and the other end of the positive busbar 26 and the negative busbar 27 (as shown in FIG. 21) extends to the first support seat 213, and the other end of the positive busbar 26 and the negative busbar 27 (as shown in FIG. Fig. 9 The rear end shown in the figure is penetrated by a magnetic ring 22 and connected to the capacitor core 23. The capacitor core 23 can be connected to a copper busbar, and the copper busbar can extend to the second support seat 214, so as to realize the electrical connection between the capacitor component 20 and the power component 30 and ensure the normal operation of the motor controller 100.

[0085] It can be understood that the first safety capacitor 24 can be connected to the positive busbar 26 and the negative busbar 27 respectively, and the first safety capacitor 24 can be grounded through the casing of the electric assembly 1000, and the second safety capacitor 25 can be connected to the positive busbar 26 and the negative busbar 27 respectively, and the second safety capacitor 25 can be grounded through the control board 50, thereby, the first safety capacitor 24 and the second safety capacitor 25 can be grounded at the nearest double point, and the two safety capacitors cooperate with the magnetic ring 22 to form a π-type filter and be grounded nearby, which can improve the filtering effect of the circuit of the motor controller 100 and improve the stability and safety of the operation of the motor controller 100.

[0086] Among them, the capacitor core 23 can be connected to a copper busbar, and the copper busbar can be connected to the control board 50. On the one hand, the electrical connection between the capacitor component 20 and the control board 50 can be realized, and the control board 50 can be fixed, which is convenient for disassembly. Since the control board 50 can be located on one side of the capacitor component 20, the power component 30 and the three-phase component 40, space can be saved and costs can be reduced. On the other hand, it is convenient for the capacitor component 20 to be grounded at high voltage through the control board 50, which can improve the safety of the motor controller 100.

[0087] like Figure 5 and Fig.10 As shown, in some examples, the power component 30 may include a power positive input terminal and a power negative input terminal, and the capacitor component 20 may include a capacitor positive output terminal and a capacitor negative output terminal, the capacitor positive output terminal and the capacitor negative output terminal are arranged on the second support seat 214, and the capacitor positive output terminal can be connected to the power positive input terminal, and the capacitor negative output terminal can be connected to the power negative input terminal, so that the electrical connection between the capacitor component 20 and the power component 30 can be realized.

[0088] like Figure 2 , 3 , Figure 4 , Figure 6 and Figure 7As shown, according to some embodiments of the present invention, the housing 10 may have a heat dissipation channel 13, the power assembly 30 may include a power module 31 and a heat dissipation module 32, and the heat dissipation module 32 may be located on a side of the power module 31 away from the control board 50 (such as Figure 7 The heat dissipation module 32 can be connected to the power module 31, and at least a portion of the heat dissipation module 32 can be located in the heat dissipation channel 13. For example, the heat dissipation module 32 can include a plurality of heat dissipation pins, and the heat dissipation pins can be located in the heat dissipation channel 13. The power module 31 can perform heat exchange with the coolant flowing in the heat dissipation channel 13 through the heat dissipation pins, thereby realizing heat dissipation of the power component 30 and improving the working stability of the power component 30.

[0089] It should be noted that when the capacitor component 20 and the three-phase component 40 are electrically connected through the power component 30, direct current can flow from the capacitor component 20 into the power component 30 (IGBT module), and then the pulse width modulation of the power component 30 converts the input direct current into alternating current of the required frequency and outputs it, and the output alternating current can pass through the three-phase component 40 and the magnetic component 42 and flow into the motor 300, thereby ensuring the normal operation of the motor 300.

[0090] like Figure 2 , Figure 3 and Figure 7 As shown, in some examples, the heat dissipation channel 13 may include a liquid inlet channel 131, a channel groove 132 and a liquid outlet channel 133, and the heat dissipation module 32 may be installed on the channel groove 132, and the heat dissipation module 32 may be sealed with the outer periphery of the channel groove 132, which can improve the sealing of the heat dissipation channel 13 and prevent the coolant in the heat dissipation channel 13 from leaking to the control board 50, thereby ensuring the reliability of the motor controller 100, and at the same time ensuring that the heat dissipation pins of the heat dissipation module 32 are in full contact with the coolant in the heat dissipation channel 13, thereby improving the heat dissipation effect on the power component 30.

[0091] The liquid inlet channel 131 and the liquid outlet channel 133 may be located on opposite sides of the channel groove 132 (eg Figure 7 The front and rear sides shown in the figure) can reduce the space occupied by the heat dissipation channel 13 in the motor controller 100 on the basis of ensuring the heat dissipation effect of the power component 30, thereby reducing the thickness of the motor controller 100 and reducing the volume and weight of the motor controller 100.

[0092] like Figure 5 and Fig.10As shown, according to some embodiments of the present invention, the three-phase component 40 may include a copper busbar component 41 and a magnetic component 42. The copper busbar component 41 can be connected to the power component 30 and the motor 300, and can supply power to the motor 300 to ensure the normal operation of the motor 300. The magnetic component 42 can be arranged on the copper busbar component 41, and the control board 50 can cooperate with the magnetic component 42 to realize the detection of the current and voltage at the three-phase ends of the copper busbar component 41, that is, after the three-phase component 40 is energized, the magnetic component 42 can generate a magnetic field under the action of the current, which is convenient for the control board 50 to detect, thereby facilitating the detection of the working state of the motor 300.

[0093] like Figure 5 and Fig.11 As shown, in some examples, the control board 50 can have multiple plug interfaces 51 and detection chips 52, and the magnetic member 42 can be U-shaped, that is, the magnetic member 42 has two parts arranged opposite to each other. During the installation of the control board 50, the two parts of the magnetic member 42 arranged opposite to each other can be respectively penetrated by a plug interface 51, and the detection chip 52 can be arranged between two adjacent plug interfaces 51, so that the detection chip 52 can be located in the middle of the U-shaped magnetic member 42, so that the detection chip 52 can communicate with the magnetic member 42, which can improve the detection effect of the detection chip 52 on the current and voltage at the three-phase end of the copper busbar assembly 41.

[0094] Among them, compared with the solution of setting a Hall injection molded part to detect the current and voltage at the copper busbar assembly 41, it can save space and reduce the thickness of the motor controller 100. At the same time, it can reduce the assembly process and number of times, thereby reducing costs; it can be understood that the number of magnetic parts 42 can be three, so that the three magnetic parts 42 can respectively correspond to the three phases of the copper busbar assembly 41, thereby realizing the detection of the current and voltage of each phase of the copper busbar assembly 41.

[0095] In some examples, the magnetic component 42 and the copper busbar assembly 41 can be integrally injection molded, which can improve the structural strength of the connection between the magnetic component 42 and the copper busbar assembly 41 and facilitate operation; wherein, the magnetic component 42 can be a silicon steel sheet, and the silicon steel sheet can be U-shaped, and the detection chip 52 can be located in the middle of the U-shaped silicon steel sheet, which can improve the detection effect of the detection chip 52 on the current and voltage at the three-phase ends of the copper busbar assembly 41.

[0096] like Figure 5 , Fig.10 and Fig.12As shown, according to some embodiments of the present invention, the motor controller 100 may further include a resolver wiring harness 60, which may include a first connection end 61, a second connection end 62 and a sealing plug 63, wherein the first connection end 61 may be connected to the motor 300, and the second connection end 62 may be connected to the control board 50, so that the motor controller 100 may establish communication with the motor 300 through the resolver wiring harness 60 to transmit signals.

[0097] The sealing plug 63 can be arranged between the first connecting end 61 and the second connecting end 62, and the sealing plug 63 can be connected to the box body 10, which can improve the sealing of the box body 10, and can reduce the probability of liquid or air entering the motor controller 100 from the motor 300 through the rotary transformer harness 60, thereby improving the working reliability of the motor controller 100.

[0098] like Figure 5 and Fig.10 As shown, in some examples, the three-phase assembly 40 may include a copper bar assembly 41 and a pressing portion 43, and the pressing portion 43 and the resolver harness 60 may be located on the same side of the copper bar assembly 41 (eg, Figure 5 The pressing portion 43 may be located at the sealing plug 63 in the second direction (eg, Figure 5 In the up and down direction shown) on one side (such as Figure 5 The upper side as shown in the figure) is used to press the sealing plug 63, which can improve the stability and reliability of the cooperation between the sealing plug 63 and the box body 10.

[0099] like Figure 5 and Fig.10 As shown, in some examples, the pressing portion 43 may be defined with a perforation 432, and the perforation 432 may be formed along the second direction (eg Fig.10 The second connection end 62 can pass through the through-hole 432 and be connected to the control board 50, so as to ensure that the motor controller 100 establishes connection with the motor 300 through the rotary transformer harness 60 and transmits signals normally. Moreover, based on that the pressing portion 43 can press the sealing plug 63, the three-phase component 40 can be prevented from interfering with the rotary transformer harness 60.

[0100] like Figure 5 and Fig.10 As shown, in some examples, the side of the pressing portion 43 away from the copper bar assembly 41 (such as Fig.10 The front side of the through hole 432 has a notch 433, which can be connected to the through hole 432, and the notch 433 can extend to both ends of the through hole 432 (such as Fig.10 The second connecting end 62 can extend into the through hole 432 through the notch 433, so as to avoid the resolver wiring harness 60 and facilitate the installation of the resolver wiring harness 60 and the three-phase assembly 40.

[0101] like Figure 5 and Fig.10 As shown, in some examples, the pressing portion 43 may include a plurality of pressing plates 431, and the plurality of pressing plates 431 may be sequentially arranged along the circumference of the through hole 432. Two adjacent pressing plates 431 in the plurality of pressing plates 431 may be arranged at intervals to define a notch 433. The side of the pressing plate 431 close to the sealing plug 63 (such as Fig.10 The lower side as shown in the figure can be bent into the through hole 432 to form a pressing section 4311, and the pressing section 4311 can press the sealing plug 63, so as to increase the contact area between the pressing portion 43 and the sealing plug 63, improve the uniformity of pressing the sealing plug 63, prevent the edge of the sealing plug 63 from curling up, and improve the sealing of the box body 10.

[0102] It is understandable that the pressing portion 43 can be a U-shaped structural member, so that the pressing portion 43 can concentrate on pressing the edge of the sealing plug 63. On the basis of ensuring the sealing effect of the sealing plug 63 on the first motor connection port 113, the rotational transformer harness 60 can be avoided.

[0103] That is, the number of the pressing plates 431 may be three, wherein two of the three pressing plates 431 are arranged at intervals, another pressing plate 431 is located between the two spaced pressing plates 431, and another pressing plate 431 is located on one side of the two spaced pressing plates 431 (e.g. Fig.10 The rear side shown in the figure) allows the three pressing plates 431 to surround the through hole 432, and allows the two pressing plates 431 arranged at intervals to be on one side away from the copper bar assembly 41 (as shown in the figure) Fig.10 The front side shown) can define a notch 433.

[0104] like Figure 5 and Fig.10 As shown, in some examples, the three-phase component 40 may include a fixing base 44, which may be connected to the copper busbar assembly 41, and the fixing base 44 may have a fastening hole, so that the fastener can pass through the fastening hole of the fixing base 44 and the fastening hole located on the box body 10, so that the three-phase component 40 can be fixed on the control board 50. Therefore, by setting the fixing base 44, the space occupied by the copper busbar assembly 41 can be reduced, the normal operation of the copper busbar assembly 41 can be ensured, and the connection strength between the three-phase component 40 and the box body 10 can be ensured.

[0105] In some examples, the housing 10 may have a first motor connection port 113, the rotary transformer wiring harness 60 may pass through the first motor connection port 113, and the sealing plug 63 may be disposed at the first motor connection port 113 to achieve sealing of the first motor connection port 113. The periphery of the first motor connection port 113 may have a positioning piece 117, and the sealing plug 63 may have a mating piece 631. The positioning piece 117 may be plugged into and mated with the mating piece 631 to achieve positioning of the sealing plug 63 and to prevent fooling around, thereby improving the accuracy of installation of the rotary transformer wiring harness 60, shortening assembly time, and facilitating operation.

[0106] It can be understood that the positioning member 117 can be a positioning column, the matching member 631 can be a positioning hole, and the positioning column can be plugged into the positioning hole to achieve the positioning of the sealing plug 63; or, the positioning member 117 can be a positioning hole, the matching member 631 can be a positioning column, and the positioning column can be plugged into the positioning hole.

[0107] like Figure 5 , Fig.10 and Fig.12 As shown, in some examples, the housing 10 may have a second motor connection port 114, the copper busbar assembly 41 may pass through the second motor connection port 114, and the copper busbar assembly 41 may be electrically connected to the power component 30 and the motor 300, respectively, to ensure the normal operation of the motor 300, wherein the operator may first install the resolver wiring harness 60, so that the pressing portion 411 may press against the sealing plug 63 of the resolver wiring harness 60 after the copper busbar assembly 41 is installed, thereby improving the sealing effect of the sealing plug 63 on the first motor connection port 113.

[0108] like Figure 2 , Figure 3 and Figure 7 As shown, according to some embodiments of the present invention, the housing 10 may have a heat dissipation channel 13, a liquid inlet 115 and a liquid outlet 116, and the liquid inlet 115 and the liquid outlet 116 may be respectively connected to the heat dissipation channel 13, that is, the coolant may flow into the heat dissipation channel 13 from the liquid inlet 115 to dissipate heat for the power component 30, and then flow out of the heat dissipation channel 13 from the liquid outlet 116, and the liquid outlet 116 may be connected to the motor 300, so that the coolant may flow through the motor 300 and the transmission 200 in sequence, thereby achieving heat dissipation for the electric assembly 1000.

[0109] A portion of the housing 10 may protrude outward to form a joint, and the joint may define a liquid inlet 115, or the joint may define a liquid outlet 116, or the joint may define both the liquid inlet 115 and the liquid outlet 116. Thus, compared with the solution of welding a pipe at the liquid inlet 115 or the liquid storage port, the probability of coolant leakage in the flow channel can be reduced, and the cost can be reduced. At the same time, the transmission 200, the motor 300 and the motor controller 100 can share a flow channel. Based on achieving heat dissipation for the electric assembly 1000, it is beneficial to reduce the space occupied by the flow channel inside the electric assembly 1000, reduce the volume of the electric assembly 1000, and improve the space utilization of the electric assembly 1000.

[0110] like Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, in some examples, the box body 10 may include a body 11 and a cover plate 12, the body 11 may define a receiving space, and the cover plate 12 may be located on the body 11 in the second direction (eg Figure 5 In the up and down direction shown) on one side (such as Figure 5 The upper side shown in FIG. 1 ) can close the accommodation space in the body 11, and the side of the body 11 facing away from the cover plate 12 (such as Figure 7 The lower side as shown has a joint protruding outward, which can define a liquid outlet 116 to facilitate the heat dissipation channel 13 to communicate with the flow channels in the motor 300 and the transmission 200, so that the transmission 200, the motor 300 and the motor controller 100 can share a flow channel.

By adopting the above-mentioned motor controller 100, the volume and weight of the electric assembly 1000 can be reduced, thereby improving the power density of the electric assembly 1000, improving the practicality of the electric assembly 1000, and reducing the occupied space inside the car, thereby improving the space utilization rate of the entire vehicle.

[0113] like Figure 1 , Figure 2 and Figure 7 As shown, in some examples, the liquid outlet 116 of the motor controller 100 is connected to the motor 300, so that the coolant in the heat dissipation channel 13 can flow through the motor 300 and the transmission 200 in sequence, thereby achieving heat dissipation for the entire electric assembly 1000, that is, the transmission 200, the motor 300 and the motor controller 100 can share a flow channel, which is beneficial to reducing the space occupied by the flow channel inside the electric assembly 1000 on the basis of achieving heat dissipation for the electric assembly 1000, reducing the volume of the electric assembly 1000, and improving the space utilization rate of the electric assembly 1000.

[0114] like Figure 5 As shown, in some examples, by moving the capacitor component 20, the power component 30 and the three-phase component 40 in a first direction (such as Figure 5 The control board 50 is arranged in the left and right direction as shown, and the capacitor component 20, the power component 30 and the three-phase component 40 are arranged in the second direction (as shown in the left and right direction). Figure 5 The second direction is perpendicular to the first direction, and the thickness of the motor controller 100 can be reduced, making the appearance of the motor controller 100 flatter. At the same time, the automatic assembly of the motor controller 100 can be realized, which can reduce the cost.

[0115] Refer to the following Figure 1-Figure 12 The installation steps of the motor controller 100 are described as follows: first, the water pipe is installed in the box 10, so that the cooling channel 13 in the box 10 can flow with the coolant, then, the capacitor assembly 20 and the resolver harness 60 are respectively installed in the box 10, and then, the three-phase assembly 40 is installed in the box 10, so that the pressing portion 43 (U-shaped structural member) of the three-phase assembly 40 presses against the sealing plug 63 of the resolver harness 60, and the power assembly 30 (IGBT module) is moved along the second direction (such as Figure 5 The power component 30 is installed on the capacitor component 20 and the three-phase component 40 in the first direction (from top to bottom as shown in FIG. Figure 5 The left and right sides as shown are fixedly connected to the capacitor component 20 and the three-phase component 40 respectively, so that the power component 30 can receive direct current from the capacitor component 20 and output alternating current to the motor 300 through the three-phase component 40.

[0116] At the same time, the DC bus connector 80 can be fixed on the first support base 213 of the capacitor assembly 20 through the first opening 112, and the low-voltage connector is pre-installed on the control board 50, and then the control board 50 is moved along the second direction (such as Figure 5 The motor controller 100 is installed in the housing 10 in the direction from top to bottom as shown, and the second connecting section of the resolver harness 60 is connected to the connector on the control board 50, and finally the cover 12 is fixed to the body 11 to close the housing 10, so that the motor controller 100 is assembled.
