Accordingly, such terms should not be construed as limitations on the present disclosure.

[0033] In the description of this disclosure, the "first feature" and "second feature" may include one or more of the features.

[0034] In the description of this disclosure, "multiple" means two or more, and "several" means one or more.

[0035] In the following, an electrical assembly 1 according to one embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0036] As shown in FIGS. 1-7, the electrical assembly 1 according to this embodiment of the present disclosure includes a box 100, an electrical control module 200, and a motor 400.

[0037] The electric control module 200 is disposed on the box 100, and the motor 400 is disposed on the box 100. The motor 400 includes a housing 410, an N-wire connection assembly 420, an end cover 430, and a three-phase winding 440 disposed within the housing 410. One end 4201 of the N-wire connection assembly 420 is configured to connect to the battery pack 900. A first end 4401 of each of the three-phase windings 440 is connected to the electric control module 200, and a second end 4402 of each of the three-phase windings 440 is connected to a junction point and then connected to the other end 4202 of the N-wire connection assembly 420. The end cover 430 is disposed at one end of the housing 410 and configured to close the housing 410, and an opening 431 is formed in the end cover 430 to allow a portion of the N-wire connection assembly 420 to pass therethrough.

[0038] According to the electrical assembly 1 of this embodiment of the present disclosure, by placing the electrical control module 200 on the box 100 and placing the motor 400 on the box 100, the box 100 can fix the electrical control module 200 and the motor 400 while protecting the electrical control module 200 and the motor 400, which is convenient for fixing the layout of the electrical control module 200 and the motor 400 and avoiding interference between the electrical control module 200 and the motor 400.

[0039] Additionally, the motor 400 includes a housing 410, an N-wire connection assembly 420, an end cover 430, and a three-phase winding 440 disposed within the housing 410. One end 4201 of the N-wire connection assembly 420 is configured to connect to the battery pack 900. A first end 4401 of each of the three-phase windings 440 is connected to the electric control module 200, and a second end 4402 of each of the three-phase windings 440 is connected to a junction and then connected to the other end 4202 of the N-wire connection assembly 420. In this manner, the battery pack 900 may be connected to the three-phase winding 440 via the N-wire connection assembly 420.

[0040] In this manner, the battery pack 900, the N-wire connection assembly 420, the three-phase winding 440, and the electrical control module 200 may be connected as a heating circuit so that the battery pack 900 can be heated, and the three-phase winding 440 of the motor 400 and the electrical control module 200 are reused, thereby reducing the number of parts, increasing space utilization, and reducing costs.

[0041] In addition, the end cover 430 is disposed at one end of the housing 410 and configured to close the housing 410, and an opening 431 is formed in the end cover 430 for the N-wire connection assembly 420 to pass through. In other words, after the N-wire connection assembly 420 is connected to the second ends 4402 of the three-phase windings 440, the N-wire connection assembly 420 may extend directly out of the housing 410 from the opening 431 of the end cover 430, so that the N-wire connection assembly 420 can be connected to the battery pack 900.

[0042] With this arrangement, compared to electrical assemblies in the related art in which the N-wire connection assembly is routed through a box and connected to the battery pack, the N-wire connection assembly 420 extends through the opening 431 in the end cover 430 and connects to the battery pack 900, thereby shortening the wiring distance. Furthermore, the wiring layout between the joining terminals of the three-phase winding 440 and the battery pack 900 is also simpler, resulting in a neater layout of the electrical assembly 1, more convenient installation and removal, and reduced weight and cost of the electrical assembly 1.

[0043] Furthermore, since the voltage between the junction terminals of the three-phase winding 440 and the battery pack 900 is usually high, the cross-sectional area of the N-wire connection assembly 420 between the junction terminals of the three-phase winding 440 and the battery pack 900 needs to be set large. In the present disclosure, the wiring of the N-wire connection assembly 420 between the junction terminals of the three-phase winding 440 and the battery pack 900 is not arranged inside the box 100, so that the volume of the box 100 can be reduced, no electromagnetic interference occurs in the electric control module 200, and the control of the electric control module 200 becomes simpler.

[0044] Thus, the electrical assembly 1 according to this embodiment of the present disclosure has the advantages of short wiring distance, simple wiring structure, and small volume.

[0045] In some specific embodiments of the present disclosure, as shown in FIG. 3, an N-wire connection assembly 420 includes an N-wire 421, an N-wire adapter 422, and an N-wire terminal block 423.

[0046] The first end 4211 of the N wire 421 is connected to the second end 4402 of each of the three-phase windings 440. The first end 4211 of the N wire 421 is the other end 4202 of the N wire connection assembly 420. The first end 4221 of the N wire adapter 422 is connected to the second end 4212 of the N wire 421, and the second end 4222 of the N wire adapter 422 passes through the opening 431. The second end 4222 of the N wire adapter 422 is the end 4201 of the N wire connection assembly 420. The first end 4231 of the N wire terminal block 423 is connected to the second end 4212 of the N wire 421, and the second end 4232 of the N wire terminal block 423 is connected to the N wire copper rod 210 of the electrical control module 200.

[0047] Furthermore, a hole 220 is arranged to extend through the N-wire copper rod 210, and the hole 220 is connected to the electrical control module 200 via a signal line.

[0048] In this way, the N-wire terminal block 423 may connect the N-wire 421 to the N-wire copper rod 210 of the electric control module 200, and the N-wire adapter 422 may connect the connecting terminal of the three-phase winding 440 to the outside of the housing 410 of the motor 400, which is convenient for connecting the connecting terminal of the three-phase winding 440 to the battery pack 900. In this way, the wiring of the N-wire connection assembly 420 is simpler and the wiring distance is shorter, which is convenient for layout.

[0049] The arrangement of the N wire 421 and the N wire terminal block 423 can realize a connection between each of the three-phase windings 440 and the vehicle's charging base, so that when the charging base is connected to a charging box with a low charging voltage (for example, the charging voltage is 450V), charging current can be induced to each of the three-phase windings 440 and the bridge arm of the electrical control module 200 via the N wire 421 and the N wire terminal block 423, and then the charging current flows to the battery pack 900 via the bridge arm of the electrical control module 200, thereby realizing boost charging of the battery pack 900.

[0050] Furthermore, the hall 220 may feed back the current value on the N-wire copper rod 210 to the electrical control module 200 through a signal line, and then detect and control the current value on the N-wire copper rod 210, thereby timely controlling the magnitude and current flow direction of the current value on the N-wire copper rod 210 and improving the reliability of circuit control.

[0051] 2, the electrical assembly 1 further includes a contactor 500. A first end 5501 of the contactor 500 is configured to connect to the battery pack 900, and a second end 5502 of the contactor 500 is configured to connect to the N-wire connection assembly 420. The contactor 500 may be attached to the battery pack 900.

[0052] Therefore, the on / off of the battery pack 900 and the N-wire connection assembly 420 may be controlled through the contactor 500, i.e., the on / off of each of the battery pack 900 and the three-phase winding 440 is controlled, so that there is no need to constantly heat the battery pack 900. In this way, if the temperature of the battery pack 900 is excessively high, the electrical connection between the battery pack 900 and each of the three-phase windings 440 may be cut off by opening the contactor 500, so that the temperature of the battery pack 900 may be prevented from becoming excessively high, which helps to improve the electrical safety of the electric assembly 1.

[0053] In some specific embodiments of the present disclosure, as shown in Figure 3, N-wire adapter 422 passes through opening 431 and then connects to N-wire nose 424. N-wire nose 424 is configured to connect to battery pack 900 via lead wires.

[0054] In other words, the N-wire nose 424 may be disposed outside the housing 410 of the motor 400, and the N-wire adapter 422 may be in communication with the battery pack 900 via the N-wire nose 424. The N-wire nose 424 is connected to one end of a lead wire, and the other end of the lead wire is connected to the battery pack 900. This arrangement makes the connection between the N-wire nose 424 and the N-wire adapter 422 more convenient, simplifies installation and removal, and ensures a more reliable connection, further improving the safety of the electrical connection after the N-wire adapter 422 extends out of the opening 431. Furthermore, the N-wire nose 424 is connected to the battery pack 900 via a lead wire, which allows the lead wire to be easily bent, making wiring more convenient, and the layout more convenient, which is beneficial to reducing the volume of the electrical assembly 1.

[0055] Furthermore, as shown in FIG. 3, the motor 400 further includes an N-wire fixed base 450 .

[0056] The N-line fixed base 450 is attached to the end cover 430. The N-line adapter 422 includes a first connector 451. The first connector 451 is inserted into the N-line fixed base 450.

[0057] Additionally, the N-wire nose 424 includes a second connector 425. The first connector 451 is connected to the second connector 425.

[0058] Specifically, the N-line fixed base 450 may be attached to the outside of the housing 410 of the motor 400, and the N-line fixed base 450 may be fixedly connected to the end cover 430. When the first connector 451 of the N-line adapter 422 extends out of the opening 431, the first connector 451 extends into the N-line fixed base 450, and then the second connector 425 of the N-line nose 424 also extends into the N-line fixed base 450. The N-line fixed base 450 may restrict the first connector 451 and the second connector 425 to facilitate connection and fixation between the first connector 451 and the second connector 425. This arrangement makes the connection between the N-line nose 424 and the N-line adapter 422 more convenient. In addition, the N-wire fixed base 450 may block the first connector 451 and the second connector 425 to prevent the first connector 451 and the second connector 425 from being exposed, further improving the reliability and safety of the electrical connection between the first connector 451 and the second connector 425.

[0059] Additionally, as shown in FIG. 3, the motor 400 further includes an N-wire attachment / detachment cover 460 .

[0060] An attachment / detachment port 452 is provided on the side of the N-wire fixed base 450 opposite the end cover 430. An N-wire attachment / detachment cover 460 is attached to the N-wire fixed base 450 and covers the attachment / detachment port 452. The attachment / detachment port 452 is configured to attach and detach at least one of the first connector 451 and the second connector 425.

[0061] In this way, when attaching or detaching the first connector 451 and the second connector 425, the N-wire attachment / detachment cover 460 may be removed first, so that the first connector 451 and the second connector 425 can be exposed from the attachment / detachment port 452, which is convenient for attaching and detaching the first connector 451 and the second connector 425. In this way, the first connector 451 and the second connector 425 can be attached and detached without completely disassembling the N-wire fixed base 450, which results in more convenient and quick attachment and detachment.

[0062] Furthermore, by locating the attachment / detachment port 452 on the side of the N-wire fixed base 450 opposite the end cover 430, the attachment / detachment port 452 is less likely to cause positional interference with the end cover 430, and the attachment / detachment port 452 has a larger operating space, which makes it more convenient to attach and detach the first connector 451 and the second connector 425 via the attachment / detachment port 452.

[0063] In some particular embodiments of the present disclosure, as shown in FIG. 3, the motor 400 further includes a first sealing ring 470 and a second sealing ring 480 .

[0064] A first sealing ring 470 surrounds the opening 431 and is disposed between the N-wire fixed base 450 and the end cover 430. A second sealing ring 480 surrounds the attachment / detachment port 452 and is disposed between the N-wire fixed base 450 and the N-wire attachment / detachment cover 460.

[0065] In this manner, the first sealing ring 470 may seal the gap between the N-wire fixed base 450 and the end cover 430, and the second sealing ring 480 may seal the gap between the N-wire fixed base 450 and the N-wire attachment / detachment cover 460, thereby sealing the internal space of the housing 410 of the motor 400 to improve the sealing performance of the motor 400.

[0066] In some particular embodiments of the present disclosure, as shown in FIG. 3, the electrical assembly 1 further includes a three-phase line connection assembly 600.

[0067] Three-phase wire connection assembly 600 includes three-phase wires 610 and a three-phase wire terminal block 620. Three-phase wires 610 are connected to each of three-phase windings 440. Three-phase wire terminal block 620 is connected to electrical control module 200. Three-phase wire terminal block 620 and N-wire terminal block 423 are integrally formed.

[0068] The arrangement of the three-phase wire terminal block 620 (for example, the three-phase wire terminal block 620 may be an injection-molded part) can ensure the reliability and safety of the electrical connection between the three-phase wires 610 and the electrical control module 200. Furthermore, the three-phase wire terminal block 620 and the N-wire terminal block 423 may be integrated into one component, which can reduce the number of parts and components and facilitate the assembly of the three-phase wire terminal block 620 and the N-wire terminal block 423, and the overall volume of the three-phase wire terminal block 620 and the N-wire terminal block 423 may be smaller, which is beneficial to reducing the volume of the electrical assembly 1.

[0069] 3, a motor terminal block slot 411 is provided on the peripheral surface of one end of the housing 410 near the end cover 430, and a three-phase wire terminal block 620 passes through the motor terminal block slot 411 and is fixedly attached to the housing 410. One end of the three-phase wire terminal block 620 connected to the motor 400 passes through the motor terminal block slot 411 and enters a cavity formed by the end cover 430 and the housing 410, and one end of the three-phase wire terminal block 620 connected to the electrical control module 200 protrudes from the motor terminal block slot 411.

[0070] Therefore, after one end of the three-phase wire terminal block 620 extends into the motor terminal block slot 411, the three-phase wire terminal block 620 may seal the motor terminal block slot 411, and the housing 410 may pre-fix the three-phase wire terminal block 620 through the motor terminal block slot 411, which is convenient for assembly. Furthermore, one end of the three-phase wire terminal block 620 connected to the electrical control module 200 extends outside the motor terminal block slot 411, which facilitates connection between the three-phase wire terminal block 620 and the electrical control module 200 and avoids positional interference between the electrical control module 200 and the housing 410 of the motor 400, resulting in more convenient assembly.

[0071] 3 , the electrical assembly 1 further includes a third sealing ring 700. The third sealing ring 700 surrounds the motor terminal block slot 411 and is located between the three-phase terminal block 620 and the end cover 430. In this manner, the third sealing ring 700 may seal the gap between the three-phase terminal block 620 and the end cover 430, and may then seal the internal space of the housing of the motor 400, further improving the sealing performance of the motor 400.

[0072] In some specific embodiments of the present disclosure, as shown in Fig. 4, the electrical assembly 1 further includes a power module 300. The power module 300 is disposed on the box 100. In addition, as shown in Fig. 7, the electrical assembly 1 further includes a water channel cover plate 800. A first water channel 810 is provided in the water channel cover plate 800. A second water channel 110 and a third water channel 120 are provided in the box 100. The water channel cover plate 800 is connected to the box 100 and covers the second water channel 110 and the third water channel 120. The water channel cover plate 800 may be integrally connected to the box 100 by friction welding.

[0073] The first water passage 810 is in communication with the second water passage 110 and the third water passage 120. The second water passage 110 is adapted to communicate with the water inlet pipe 130, and the third water passage 120 is adapted to communicate with the water outlet pipe 140. The cooling liquid in the second water passage 110 flows into the first water passage 810, thereby dissipating heat from the electrical control module 200. The cooling liquid in the first water passage 810 flows into the third water passage 120, thereby dissipating heat from the power module 300.

[0074] In other words, the first water passage 810, the second water passage 110, and the third water passage 120 form a connected water passage, and the coolant in the first water passage 810, the second water passage 110, and the third water passage 120 may be shared. Furthermore, the second water passage 110 and the third water passage 120 may be sealed via the water passage cover plate 800 to prevent the coolant in the second water passage 110 and the third water passage 120 from leaking. In addition, the coolant in the third water passage 120 may exchange heat with the power module 300 through the outer wall of the third water passage 120. In this way, the temperature of the power module 300 may be reduced, so that the power module 300 is maintained in a low temperature or normal temperature state, which in turn improves the operational stability of the power module 300 and prevents damage to the power module 300 due to high temperatures.

[0075] Furthermore, the first water passage 810, the second water passage 110, and the third water passage 120 are in communication with each other. The flow path of the coolant becomes longer. The coolant in the second water passage 110 may flow into the first water passage 810 to dissipate heat from the electrical control module 200, and similarly, the coolant in the first water passage 810 may flow into the third water passage 120 to dissipate heat from the power module 300. This is beneficial for increasing the utilization rate of the coolant.

[0076] In some particular embodiments of the present disclosure, as shown in FIG. 6, the third water passage 120 includes a transition section 121 and an annular section 122 .

[0077] The transition portion 121 comes into communication with the first water passage 810. The annular portion 122 surrounds the power module 300 and is configured to dissipate heat from the power module 300. One end of the annular portion 122 is connected to one end of the transition portion 121, and the other end of the annular portion 122 is provided with a water outlet hole 123. The depth of the annular portion 122 is greater than the depth of the second water passage 110 and the depth of the transition portion 121.

[0078] For example, the coolant flows into the second water passage 110 and then into the first water passage 810. The coolant in the first water passage 810 then flows into the transition section 121 and finally flows from the transition section 121 to the annular section 122 and is discharged through the water outlet holes 123 in the annular section 122.

[0079] Furthermore, the contact area between the annular portion 122 and the power module 300 is larger, and the structure of the annular portion 122 is more compact and occupies less space. By using the annular portion 122 to dissipate the heat of the power module 300, the heat exchange effect between the third water passage 120 and the power module 300 may be improved, and then the power module 300 can be cooled quickly, thereby achieving a better heat dissipation effect.

[0080] In addition, the depth of the annular portion 122 is greater than the depth of the second water passage 110 and the depth of the transition portion 121. In this way, on the one hand, the volume of the annular portion 122 may be larger, and the annular portion 122 may accommodate more cooling liquid, thereby improving the heat dissipation effect of the power module 300 by the annular portion 122. On the other hand, the transition between the second water passage 110 and the first water passage 810 may be smoother, the transition between the transition portion 121 and the first water passage 810 may be smoother, and the circulating flow of the cooling liquid between the third water passage 120 and the first water passage 810 may be smoother, so that the cooling liquid can sufficiently exchange heat with the power module 300, thereby further improving the heat dissipation effect of the power module 300.

[0081] In some specific embodiments of the present disclosure, as shown in FIG. 4 , the power module 300 includes a base plate 310, a transformer 320, a transformer inductor 330, a plurality of MOS tubes 340, an AC inductor 350, and a DC inductor 360.

[0082] The bottom plate 310 has a first direction and a second direction that are perpendicular to each other. The transformer 320 and the transformer inductor 330 are attached to the bottom plate 310 and extend along the first direction. The multiple MOS tubes 340 are attached to the bottom plate 310 and are separately arranged on either side of the transformer 320 in the second direction. The AC inductor 350 and the DC inductor 360 are attached to the bottom plate 310 and are separately arranged on either side of the MOS tube 340 in the second direction. The third water passage 120 surrounds the transformer 320 and the transformer inductor 330, and the multiple MOS tubes 340 are located on either side of the third water passage 120 and exchange heat with the third water passage 120.

[0083] In this manner, the bottom plate 310 may be configured to fix the transformer 320, the transformer inductor 330, the plurality of MOS tubes 340, the AC inductor 350, and the DC inductor 360. To avoid interference between the AC inductor 350 and the DC inductor 360, the AC inductor 350 and the DC inductor 360 may be spaced apart from each other. Furthermore, the transformer 320, the transformer inductor 330, the plurality of MOS tubes 340, the AC inductor 350, and the DC inductor 360 are more evenly arranged on the bottom plate 310, thereby avoiding electromagnetic interference between multiple parts and components.

[0084] In addition, the third water passage 120 surrounds the transformer 320 and the transformer inductor 330. The multiple MOS tubes 340, the AC inductor 350, and the DC inductor 360 are located outside the third water passage 120 and attached to the outer wall of the third water passage 120. The third water passage 120 may dissipate heat from the transformer 320, the transformer inductor 330, the multiple MOS tubes 340, the AC inductor 350, and the DC inductor 360, thereby improving the heat dissipation efficiency of the power module 300.

[0085] 4, a box 100 is provided with a plurality of MOS tube cavities 150, an AC inductor cavity 160, and a DC inductor cavity 170. An AC inductor 350 extends into the AC inductor cavity 160, a DC inductor 360 extends into the DC inductor cavity 170, and a plurality of MOS tubes 340 extend into a plurality of MOS tube cavities 150 in a one-to-one correspondence.

[0086] In this way, the MOS tube cavity 150 may shield the MOS tube 340, the AC inductor cavity 160 may shield the AC inductor 350, the DC inductor cavity 170 may shield the DC inductor 360, and the sidewalls of the third water passage 120 can shield the transformer 320 and the transformer inductor 330, thereby further avoiding electromagnetic interference between the MOS tube 340, the AC inductor 350, the DC inductor 360, the transformer 320, and the transformer inductor 330, and avoiding interference with external electronic devices, which is beneficial to improving electromagnetic compatibility.
