[0051] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0052] It should be noted that the first direction ZZ of the present application indicates the up-down direction only for the convenience of introducing the specific embodiments of the present application. There is no absolute corresponding relationship between the first direction ZZ and the up-down direction. Similarly, there is no absolute corresponding relationship between the second direction X and the left-right direction, and the third direction Y and the front-back direction. Moreover, the first direction Z, the second direction X, and the third direction Y of the present application are only for expressing relative positional relationships. They only indicate approximate directions, not absolute geometric relationships.

[0053] According to the first aspect of the present application, referring to Figures 1 to 3 The present application provides an isolating member 200 , which is used to isolate a first conductive row 310 and a second conductive row 320 . The isolating member 200 includes a main body 210 and a side retaining wall 220 .

[0055] A plurality of side retaining walls 220 are provided, and the plurality of side retaining walls 220 are spaced apart in the second direction X, dividing the space on one side of the main body 210 in the third direction Y (front-rear direction) into a first type of partition space 200a and a second type of partition space 200b separated by the side retaining walls 220.

[0056] The first type spacing spaces 200a and the second type spacing spaces 200b are alternately arranged in the second direction X. The first type spacing spaces 200a are only used to arrange at least a portion of the first conductive row 310 , and the second type spacing spaces 200b are only used to arrange at least a portion of the second conductive row 320 .

[0057] Through the above technical solution, the first conductive row 310 and the second conductive row 320 are isolated in the first direction Z through the main body 210, and the first conductive row 310 and the second conductive row 320 are isolated in the second direction X through the side retaining wall 220, thereby ensuring the electrical gap between the first conductive row 310 and the second conductive row 320, and effectively reducing the spatter (such as welding chips) pollution during welding.

[0058] In some embodiments, reference Figure 1 and Figure 2 The isolation member 200 further includes an end retaining wall 230 .

[0059] Specifically, the end retaining wall 230 is arranged between the two side retaining walls 220 and extends along the second direction X. The end retaining wall 230 is configured to isolate the first conductive row 310 and the second conductive row 320 at least in the third direction Y (front-to-back direction). The first direction Z and the second direction X are both perpendicular to the third direction Y.

[0060] Through the above technical solution, the first conductive bar 310 and the second conductive bar 320 are isolated in the third direction Y by the end retaining wall 230. And the combination of the end retaining wall 230 and the side retaining wall 220 can increase the strength of both and the strength of the main body 210. At the same time, the combination of the end retaining wall 230 and the side retaining wall 220 can further avoid spatter pollution during welding, which can not only improve the welding quality but also reduce the cost.

[0061] As an optional solution, the end retaining wall 230 is combined with the end retaining wall 230 by integral molding, adhesive fixation, or detachable connection.

[0062] In some embodiments, reference Figure 1 and Figure 2 The main body 210 includes: a main isolation surface 211.

[0065] Through the above technical solution, by setting the main isolation surface 211, a plane for the first conductive row 310 and the second conductive row 320 to attach to is provided, and at the same time, the isolation distance between the first conductive row 310 and the second conductive row 320 in the first direction Z can be limited by the distance between the two main isolation surfaces 211.

[0066] In some embodiments, reference Figure 1 and Figure 2 The side retaining wall 220 includes: a side isolation surface 221 and an end isolation surface 231.

[0079] Through the above technical solution, the external reinforcing ribs 240 are arranged between the side retaining wall 220 and the main body 210, which can further improve the structural strength of the side retaining wall 220 or the main body 210.

[0081] It can be understood that in the second direction X, the size of the first conductive row 310 that can be accommodated in the first type of spacing space 200 a is smaller than the size of the second conductive row 320 that can be accommodated in the second type of spacing space 200 b .

[0082] Through the above technical solution, the relative sizes of the first type of spacing space 200 a and the second type of spacing space 200 b are limited to meet the size and arrangement requirements of the first conductive row 310 and the second conductive row 320 .

[0101] In some embodiments, reference Figure 4 and Figure 6 The first connection part 311 and the second connection part 321 are both provided with a detection hole 300a for detecting the welding gap, and the detection hole 300a passes through the first connection part 311 and the second connection part 321 along the first direction Z respectively.

[0102] In the present application, the welding gap is the gap size when the first connection portion 311, the second connection portion 321 and the external conductive bar to be welded overlap.

[0103] Through the above technical solution, before welding, the welding gap between the first conductive bar 310 or the second conductive bar 320 and the external conductive bar to be welded can be detected through the detection hole 300a to ensure that the first conductive bar 310 or the second conductive bar 320 and the external conductive bar are tightly fitted, thereby improving the quality of welding, avoiding the risk of the first conductive bar 310 or the second conductive bar 320 or the external conductive bar being welded through due to an excessively large welding gap, thereby reducing the cost of scrapping.

[0104] According to the third aspect of the present application, reference Figures 8 to 18 , a vehicle 400 is provided, the vehicle 400 includes the above-mentioned conductive bar assembly 300, and the vehicle 400 has all the beneficial effects of the above-mentioned conductive bar assembly 300, which will not be repeated in this application.

[0105] The vehicle 400 may be a fuel vehicle, a plug-in hybrid vehicle, a new energy vehicle, etc., and this application does not make any specific limitation on this.

[0106] In some embodiments, the vehicle 400 further includes: a motor 410 , an IGBT module 420 , and a capacitor module 430 .

[0107] Specifically, the IGBT module 420 is used to realize the driving of the motor 410; the capacitor module 430 is at least used to realize the voltage adjustment of the IGBT module 420; at least one of the first conductive row 310 and the second conductive row 320 is physically connected between the IGBT module 420 and the capacitor module 430 to make the IGBT module 420 and the capacitor module 430 electrically connected.

[0108] As an optional solution, the first conductive bar 310 and the second conductive bar 320 can be used as part of the capacitor module 430, that is, the first conductive bar 310 is used as the capacitor negative electrode output copper bar, and the second conductive bar 320 is used as the capacitor positive electrode output copper bar. Correspondingly, the above external conductive bars can be the IGBT positive electrode input copper bar 76 and the IGBT negative electrode input copper bar 77 of the IGBT module 420.

[0109] As another optional solution, the first conductive bar 310 and the second conductive bar 320 may be part of the IGBT module 420 , or the first conductive bar 310 and the second conductive bar 320 may be independent modules to form an electrical connection between the IGBT module 420 and the capacitor module 430 .

[0110] To facilitate understanding of the inventive concept of the present application, the following describes in detail the vehicle provided by some embodiments of the present application. The vehicle 400 provided by some embodiments of the present application includes an integrated controller, wherein the integrated controller includes the conductive bar assembly 300 mentioned in the above embodiment. Fig. 9is a schematic diagram of the integrated controller circuit topology provided in an exemplary embodiment of the present application. Fig. 9 As shown, the entire integrated controller circuit can be divided into two parts: the electric assembly 440 and the battery pack. The integrated electric control of the electric assembly has a DC charging line nose 4 and an AC charging and discharging connector 3, which can realize AC charging and DC charging functions. The battery pack may include multiple battery packs. In this embodiment, two battery packs are used as an example for explanation, that is, the battery pack includes a first battery pack U1 and a second battery pack U2. There is an N line between the first battery pack U1 and the second battery pack U2 and is connected to the drive motor MG.

[0111] When the DC power is connected to charge the vehicle, the positive pole of the current passes through the DC charging line nose 4 and the DC charging magnetic ring 110, and then passes through the DC charging positive copper bus 116 and the contactor 121, and then passes through the bus magnetic ring 87 and the DC bus line nose 9 to flow directly to the battery pack; the other way passes through the DC charging negative copper bus 115 and the contactor 121, and then passes through the bus magnetic ring 87 and the DC bus line nose 9 to flow to the battery pack. When the charging pile voltage is lower than the vehicle voltage and needs to be boosted to charge the vehicle, the current passes through the DC charging positive copper bus 116, passes through the N line boost contactor 119, enters the inductance of the drive motor MG, completes the boost, passes through the electronically controlled IGBT module 420, passes through the smoothing capacitor 154, and then passes through the bus magnetic ring 87 and the DC bus line nose 9 to flow to the battery pack. At this time, the capacitor and IGBT connection circuit are reused, thereby saving circuit space and cost. In order to absorb the ripple current in the circuit, the current passes through the DC positive pole through the N-line boost contactor 119 and is also connected to the boost capacitor 155. When charging, the current passes through the IGBT module 420. The IGBT module 78 will make the battery pack on the vehicle charge and discharge through current oscillation at high frequency, so that the battery pack will self-heat during charging, thereby improving the charging efficiency. It should be noted that the contactor 121 can be a DC two-in-one contactor or other contactors that can achieve the same function.

[0112] When the charging pile voltage is higher than the vehicle voltage and the charging pile voltage needs to be lowered and the charging pile current needs to be increased to speed up the charging of the vehicle, the current enters the smoothing capacitor 154 and the electronically controlled IGBT module 420 through the DC charging positive copper bus 116 and the contactor 121, and completes the current increase through the inductance of the motor. After that, the current flows from the N-line transfer copper bus 84 and the N-line copper bus 128 through the bus magnetic ring 87 and the DC bus line nose 9 to the battery end voltage divider contactor 153 and then flows to the battery pack. At this time, the capacitor and IGBT connection circuit are reused again, thereby saving circuit space and cost. The entire boost and current increase fully utilize the L / C circuit formed by the electronically controlled capacitor and the motor inductance for boost or buck charging, and both share the N-line circuit, saving electronic devices and line costs and space.

[0113] When the battery pack supplies power to the vehicle, the positive and negative electrodes pass through the DC bus line nose 9, the bus magnetic ring 87 and the smoothing capacitor 154. When the upper bridge is turned on and the lower bridge is turned off, U1 discharges, and the current charges the three-phase inductor through the IGBT. When the lower bridge is turned on and the upper bridge is turned off, the inductor continues to charge U2, and then forms a loop through the lower bridge diode; when the lower bridge is turned on and the upper bridge is turned off, U2 discharges and forms a loop through the lower bridge IGBT. When the upper bridge is turned on and the lower bridge is turned off, the inductor continues to charge U1 through the upper bridge diode. In this way, the two battery packs are charged and discharged to make the internal resistance of the battery heat up, realizing battery self-heating. At the same time, the excess current when U1 or U2 supplies power to the IGBT can also be recovered to save energy.

[0114] The negative pole of the DC / OBC (direct current / on-board charger) power module directly draws power from the negative pole of the DC, and the positive pole passes through the small fuse 130. The AC charging and discharging connector 3 is connected to the power charging and discharging module. During AC charging, the current flows to the battery pack through the DC / OBC module and the small fuse 130; when the vehicle is discharging, the battery pack current flows to the discharge socket in the vehicle after passing through the charging and discharging module.

[0115] from Fig. 9 It can be seen that no matter the battery pack supplies power to the IGBT and the motor, or the DC step-up / step-down charging, the positive and negative poles of the DC bus (corresponding to the DC charging positive copper bus 116 and the DC charging negative copper bus 115, respectively) and the N line will pass through the same bus magnetic ring 87, which can suppress the common mode voltage of the three lines of the DC bus positive and negative poles and self-heating, and achieve the suppression of high-frequency noise; at the same time, the self-heating line and the battery DC bus positive and negative lines flow to the battery pack together after electronic control, and the self-heating harness will reuse the negative or positive pole of the bus, which is also beneficial to the vehicle line layout and cost saving.

[0116] Fig.10 Schematic diagram of the surrounding structure of the electric assembly provided in an exemplary embodiment of the present application. Fig.10 As shown, the integrated controller includes an upper cover 1 and a DC charging small cover 2, a DC busbar small cover 12 and a three-phase small cover 15 respectively arranged on the upper cover 1 for connecting the high-voltage wire harness. The AC charging and discharging connector 3, the DC charging line nose 4, and the DC busbar wiring nose 9 are located in the axial direction of the electric assembly, that is, the direction of the door. This wiring harness arrangement method can avoid or reduce the damage to the high-voltage wire harness during a frontal collision of the vehicle, thereby avoiding short circuit fire after the collision. The two sides of the motor housing 13 are the gearbox housing 11 and the motor front box 14, respectively. The gearbox housing 11 also has an oil cooler 5 and an oil cooler water inlet pipe 8 and an oil cooler water outlet pipe 6. The soft water pipe 7 is connected to the oil cooler water inlet pipe 8 by the electronic control.

[0117] like Fig.11 , Fig.12 and Fig.13As shown, the integrated controller box is mainly composed of two parts: the electric control box 10 and the waterway cover 37. The electric control box 10 is divided into two cavities, the upper cavity 16 and the lower cavity 47. The upper cavity 16 is isolated by the shielding ribs and the side walls of the box to form a power harness cavity 22. The upper cavity 16 is mainly equipped with electronic components of the electric control and power distribution parts, and the lower cavity 47 is mainly equipped with power module components, so that the power module will not interfere with the electric control when working. The upper cavity 16 is provided with vias for connecting various harnesses, including: DC bus connector vias 17, DC charging connector vias 19, AC charging and discharging connector vias 20, DC connector vias 29, signal connector vias 30 and three-phase component vias 34, etc. The upper cavity 16 has structures such as an electric control water channel passage 31 for water channel heat dissipation, a power water channel passage 36, a power three-dimensional water channel water inlet 35, a three-dimensional water channel A area 33, a three-dimensional water channel B area 25, and a three-dimensional water channel C area 18. The water channel cover plate 37 has structures such as an IGBT mounting surface 42 for assembling an IGBT module 420, an IGBT sealing ring groove 39, an IGBT water channel water inlet 38, an IGBT water channel 43, an IGBT water channel passage 40, and an IGBT water channel outlet 41. The water channel cover plate 37 is connected to the upper cavity 16 by friction welding. There are also AC charging line vias 23, DC transfer copper busbar vias 24, power signal line vias 26, and DC / OBC input line vias 27 for connecting the upper and lower cavity wiring harnesses between the upper cavity 16 and the lower cavity 47. The box body also has shielding ribs and box body side walls to form a DC output shielding cavity 28 to prevent the DC output from being interfered by other electronics and facilitate EMC (Electromagnetic Compatibility). The electric control box body 10 is equipped with an electric control water inlet pipe 49 and an electric control water outlet pipe 56.

[0118] The power heat dissipation rib a 48 and MOS tube shielding rib a 45, the power heat dissipation rib c 55 and the MOS tube shielding rib b 52 on the lower cavity 47 respectively form a plurality of shielding cavities such as MOS tube shielding cavity a 46, MOS tube shielding cavity b 53, inductor transformer shielding cavity 54, DC inductor cavity 51, AC inductor cavity 44, etc. The electric control box 10 is divided into upper and lower cavities and a plurality of small cavities in this way, which is conducive to preventing mutual interference between power modules, thereby improving the EMC effect.

[0119] like Figures 14 to 18As shown, the capacitor module 430 integrates three fuse placement positions: the driving negative electrode fuse placement position 64, the DC charging positive electrode fuse placement position 65 and the small fuse placement position 158. The IGBT smoothing capacitor 154 and the boost capacitor 155 are all inside the shell of the capacitor module 430. Because this capacitor is shared with another version of the self-heating function integrator, there is an N-line transfer copper bar lap column 59 for connecting the N line between the capacitor DC bus positive electrode lap copper bar 58 and the DC bus negative electrode lap copper bar 60. The capacitor positive electrode input copper bar 67 and the capacitor negative electrode input copper bar 68 are located on the same side of the capacitor as the above-mentioned features. On the other side of the capacitor are the boost capacitor positive electrode input copper bar 70, the capacitor positive electrode output copper bar 72, and the capacitor negative electrode output copper bar 75. The capacitor positive electrode output copper bar 72 and the capacitor negative electrode output copper bar 75 both have detection holes 300a for measuring the height dimensions between the copper bars. There is an isolating piece 200 for isolating the positive and negative output copper bars of the capacitor between the positive output copper bar 72 and the negative output copper bar 75 of the capacitor. The isolating piece 200 has a positioning column 157 and a side retaining wall 220 for assembling the output copper bar of the capacitor and the capacitor. The side retaining wall 220 can not only isolate the positive and negative copper bars of the IGBT to increase the safety distance, but also block the spatter during welding. It can be understood that the welding involved in the embodiment of the present application can be laser welding or other welding methods suitable for circuit boards.

[0120] like Fig.14 , Fig.15 and Fig.18 As shown, the output copper bar of the capacitor and the input copper bar of the IGBT module do not have holes for screw connection, so welding is required. The advantage of this is that the positive and negative output copper bars of the capacitor can be made into a laminated busbar structure, and the input copper bar of the IGBT can be made into a laminated busbar structure, thereby reducing the stray inductance of the power device during operation, thereby reducing the ripple voltage and improving product reliability and work efficiency. In addition, laser welding can reduce the inadequate connection between the two copper bars relative to the screw connection method, thereby reducing the contact resistance and reducing energy loss. The welding assembly sequence of the copper bars of the capacitor and the IGBT is as follows: first install the IGBT module 420 into the electric control box and then assemble the capacitor module 430, so that the capacitor positive output copper bar 72 and the IGBT positive input copper bar 76 are overlapped and connected, and then the two copper bars are closely connected by laser welding; the capacitor negative output copper bar 75 and the IGBT negative input copper bar 77 are connected by laser welding to make the three copper bars connected and conductive.

[0121] like Fig.16 and Fig.17As shown, there is an IGBT sealing ring 90 between the IGBT module 420 and the IGBT water channel passage 40. Above the IGBT module 420, there are an IGBT driving board 82, a shielding plate bracket 80, a control board 81 and an upper cover 1 in sequence, that is, the IGBT driving board 82 and the control board 81 are separated by a shielding plate bracket 80 to prevent the IGBT driving board 82 from interfering with the signal on the control board 81 when working. The three-phase transfer copper bus 94 and the AC output copper bus of the IGBT module 420 are fixed on the AC copper bus fixing seat 93, and the three-phase transfer copper bus 94 will pass through the AC Hall 95 to flow the three-phase current to the motor end. After the capacitor positive output copper bus 72 is overlapped on the DC positive input copper bus 76 of the IGBT module 420 and connected by laser welding, the capacitor negative output copper bus 75 and the IGBT negative input copper bus 77 are connected by laser welding. From Fig.12 It can be seen more clearly that the positive and negative output copper bars of the capacitor and the input copper bar of the IGBT are an upper and lower stacked busbar structure, which can reduce the stray inductance of the power device when it is working, reduce the ripple voltage, and thus improve product reliability and work efficiency; at the same time, compared with the screw connection method, laser welding can avoid insufficient connection between the two copper bars as much as possible, thereby reducing contact resistance and reducing energy loss.

[0122] Directly below the water channel is the inductor transformer shielding cavity 54, in which a high-power, easily heated transformer 89 component is installed; the two sides of the inductor transformer shielding cavity 54 are respectively the three-dimensional water channel C area 18 and the three-dimensional water channel A area 33, that is, the inductor transformer shielding cavity 54 is surrounded by water in a multi-directional and three-dimensional manner. The power supply heat dissipation rib a 48 and the MOS tube shielding rib a 45 form the MOS tube shielding cavity a 46. While the MOS tube 88 is cooled by the water in the three-dimensional water channel A area 33, it also obtains a good shielding effect to avoid interference with external electronic devices. Similarly, the power supply heat dissipation rib c 55 and the MOS tube shielding rib b 52 form the MOS tube shielding cavity b 53. While the MOS tube 88 is cooled by the water in the three-dimensional water channel C area 18, it also obtains a good shielding effect. The DC inductor cavity 51 and the AC inductor cavity 44 are respectively on the left and right edges of the lower cavity of the power supply, so as to avoid AC / DC interference.

[0123] Fig.13 is a schematic diagram of the power module assembly provided in an exemplary embodiment of the present application, such as Fig.13As shown, first install the DC transfer copper bar a assembly 100 into the lower cavity 47, and respectively connect one end of the DC / OBC power line 105 and the in-vehicle emergency charging line 104 to the upper cavity 16 through the DC / OBC input line through hole 27 and the AC charging through hole 23, and the other end is waiting to be connected to the power board assembly 91; then connect the power signal line a 97 and the power signal line b92 on the power signal transfer PCB 102 to the upper cavity 22 through the power signal line through hole 30, and then fix the power signal transfer PCB 102 to the lower cavity 47. Then install the power board assembly 91 in the lower cavity 47, and install the MOS tube 88 on the power heat dissipation rib a 48 and the power heat dissipation rib c 55 respectively, and install the DC inductor 101, the transformer inductor 97 and the transformer 89, the AC inductor 96 and other electronic devices into the corresponding DC inductor cavity 51, the inductor transformer shielding cavity 54 and the AC inductor cavity 44. The signal on the power board assembly 91 is connected to the power signal transfer PCB 102 through the signal pin 99, and then connected to the control board 81 through the power signal line a103 and the power signal line b98 on the power signal transfer PCB 102, and finally connected to the vehicle through the signal connector on the control board 81 for control. After the DC / OBC power line 105, the in-vehicle emergency charging line 104 and the power board assembly 91 are connected, the lower cover 92 is installed, and the power module assembly is completed.

[0124] Fig.14 is a schematic diagram of an electric control electronic device and a power distribution assembly provided in an exemplary embodiment of the present application, such as Fig.14As shown, the box with the power module installed is respectively installed with the DC adapter plug 106 and the AC charge and discharge connector 3, and then the DC adapter copper bus b component 107 is installed, so that one end of it is connected to the DC adapter plug 106, and the other end is connected to the DC adapter copper bus a component 100 through a screw at the DC adapter copper bus through hole 24; then the DC shielding plate 111 and the AC harness shielding plate 113 are respectively installed to prevent the DC current and AC charge and discharge current from being interfered; then the charge and discharge filter board 112 is installed above the AC harness shielding plate 113, and the charge and discharge PCB board 114 is installed on the box, and the AC charge and discharge harness on the AC charge and discharge connector 3 and the other end of the in-vehicle emergency charging line 104 are connected to it. After the AC copper busbar fixing base 93, the DC magnetizing ring assembly 108, the N-line copper busbar fixing base 118, the contactor 121, the N-line boost contactor 119, the busbar magnetic ring assembly 125 and other parts are installed on the box body, the DC terminal fixing base 83 is fixed to the upper cavity 16 with the stud 129, the IGBT sealing ring 90 is installed into the IGBT sealing ring groove 39, the IGBT module 420 is installed into the IGBT water channel 43, and then the side pressure block and the middle pressure block are placed to fix the IGBT module 420, and then the drive board 82 is placed, and the drive board is fixed to the middle pressure block 127 and the side pressure block 126 by bolt connection, so that the side pressure block 126 and the middle pressure block 127 complete the fixation of the IGBT module 420 and the drive board 82, and the three-phase transfer copper busbar 94 is fixed. After passing through the AC Hall 95, one end is connected to the AC output copper bar of the IGBT module 420 and fixed on the AC copper bar fixing seat 93, and the other end is waiting to be connected to the motor; at this time, the capacitor module 430 with the driving negative electrode insurance 132, the boost charging positive electrode insurance 131 and the small insurance 130 is installed, and the capacitor positive electrode output copper bar 72 and the IGBT positive electrode input copper bar 76 are overlapped and connected, and the capacitor negative electrode output copper bar 75 and the IGBT negative electrode input copper bar 77 are connected. Before welding, the height size between the copper bars can be detected through the detection hole 300a to ensure that the copper bars are closely fitted to the copper bars and thus the quality of welding can be avoided. The risk of the copper bar of the capacitor or IGBT being welded through due to the excessive welding gap can be avoided, thereby reducing the cost of scrapping, so that the three copper bars are connected and turned on. Then the positive and negative poles of the DC bus line nose 9 are connected to the DC bus positive electrode overlap copper bar 85 and the DC bus negative electrode overlap copper bar 86 respectively.One end of the N-line copper bar 128 is fixed on the AC copper bar fixing seat 93 to wait for connection with the motor, and the other end is placed on the N-line copper bar fixing seat 118 and connected and fixed with one end of the N-line boost contactor transfer copper bar 117, and the other end of the N-line boost contactor transfer copper bar 117 is connected to the N-line boost contactor input copper bar 124; the other end of the N-line boost contactor input copper bar 116 is connected to the input end of the N-line boost contactor 119, one end of the boost capacitor positive electrode transfer copper bar 120 is connected to the output end of the N-line boost contactor 119, and the other end is connected to the boost capacitor positive electrode input copper bar 70 of the capacitor module 430. From. Fig.14 It can be seen from the figure that the N-line boost contactor 119 is a horizontal one with the copper busbar connection point facing the direction of the DC bus line nose 9, i.e. the direction of the vehicle door. This has the advantage of preventing the contactor from being mistakenly attracted due to the inertia force of sudden acceleration and deceleration or bumpy road conditions during driving. Since the contactor is always connected to the motor, current will be conducted. If the contactor is mistakenly attracted, there will be a risk of electric shock. One end of the DC charging positive copper bar 116 is fixedly connected to the input end of the contactor 121, and the other end is connected to the DC charging line nose 4 and fixed to the DC magnetizing ring assembly 108. The DC charging positive copper bar 116 also has a branch connected to the boost capacitor positive pole transfer copper bar 120; one end of the DC charging positive pole transfer copper bar 84 is connected to the output end of the contactor 121, and the other end is fixedly connected to the DC bus positive pole lap copper bar 58 of the capacitor module 430; one end of the DC charging negative pole transfer copper bar b123 is connected to the DC charging negative pole transfer copper bar 85 and fixed to the DC charging negative pole transfer copper bar fixed position 69 of the capacitor module 430, and the other end is connected to the output end of the contactor 121; one end of the DC charging negative pole copper bar 115 is connected to the output end of the contactor 121, and the other end is connected to the negative pole of the DC charging line nose 4 and fixed to the DC magnetizing ring assembly 108. The positive pole of the DC / OBC power line 105 is connected to the small fuse 130, and the negative pole is connected to the negative power point of the DC charging and negative pole transfer copper bar a86, so that the power connection of the DC / OBC power supply is turned on. Then install the shielding plate bracket 80 and fix it on the stud by bolts, so that the stud can fix both the DC terminal fixing seat 83 and the shielding plate bracket 80, reducing the space occupied by the bolts, and then put in the control board 81, and connect the power signal line a103 to the control board 81, and the power signal line b98 to the charge and discharge filter board 112; the IGBT drive board 82 is connected to the control board 81 through the PWM harness 133 to transmit the control signal; one end of the Hall and the black transformer connector is connected to the control board 81, and the other end is waiting to be connected to the motor black transformer connector, and finally the upper cover 1 is installed, and the entire electric control assembly is completed.

[0125] Combination Fig. 9 Integrated controller circuit topology diagram and Fig.14The schematic diagram of the electric control electronic devices and power distribution assembly further illustrates the working principle of the integrated controller: after the current of the battery pack passes through the DC bus line nose 9, the positive electrode passes through the DC bus positive electrode bridging copper busbar 58 and then flows into the capacitor positive electrode input copper busbar 67 through the boost charging positive electrode fuse 131 and flows to the smoothing capacitor 154 to supply power to the IGBT module 420; the negative electrode passes through the DC bus negative electrode bridging copper busbar 60 and passes through the driving negative electrode fuse 132 to connect to the capacitor negative electrode to the smoothing capacitor 154 and then flows through the capacitor output copper busbar 75 to supply power to the IGBT module 420. When the vehicle is charged with DC, the positive current passes through the DC charging line nose 4, the DC charging magnetic ring 110 and the DC charging Y capacitor 109, then passes through the DC charging positive copper bus 116 and the DC two-in-one contactor 121, and then flows to the battery pack through the bus magnetic ring 87 and the DC bus line nose 9; the negative current passes through the DC charging line nose 4, the DC charging magnetic ring 110 and the DC charging Y capacitor 109, and then flows to the battery pack through the bus magnetic ring 87 and the DC bus line nose 9.

[0126] When in boost charging, the positive current will flow into the motor through the DC charging positive copper bar 116 and the boost capacitor positive transfer copper bar 120, then through the N-line boost contactor 119 and the N-line boost contactor output copper bar 124, the N-line boost contactor transfer copper bar 117 and the N-line copper bar 83, and then through the motor boost, then through the IGBT module 420 and the smoothing capacitor 154, and then through the bus magnetic ring assembly 125 and the DC bus line nose 9 to the battery pack. The negative current is the same as the route when not boosted, through the DC charging negative copper bar 115 and the DC charging negative transfer copper bar 123, and then through the bus magnetic ring assembly 125 and the DC bus line nose 9 to the battery pack. The inductance of the motor during boost charging reuses the internal inductance of the motor, and at the same time, the voltage is increased to charge the battery, forming an L / C circuit.

[0127] Fig.11 Schematic diagram of the integrated controller and motor assembly provided in the exemplary embodiment of the present application. Fig.11As shown, after the motor terminal block seal ring 145 is installed into the terminal block seal ring groove 135 of the motor housing, the motor terminal block 142 and the motor transformer socket 137 are respectively installed on the motor housing, and then the electric control three-phase seal ring 146 is installed into the three-phase seal ring groove 136, and then the integrated controller assembly is installed above the motor and connected and fixed with the electric control mounting screws. The electric control outlet pipe 56 and the oil cooler inlet pipe 8 of the transmission are connected with the connecting soft water pipe 7. In this way, the heat dissipating water from the electric control inlet pipe 49 to the electric control and power supply components through the internal water channel of the integrated electric control flows from the electric control outlet pipe 56 through the connecting soft water pipe 7 and the oil cooler inlet pipe 8 to the oil cooler 5 to dissipate the heat dissipation oil of the electric assembly, and then flows out from the oil cooler outlet pipe 6. Open the three-phase small cover 15 of the integrated controller, use screws to connect the three-phase transfer copper bar 91 and the N line copper bar 128 of the integrated controller to the electric control three-phase connection terminal 143 and the electric control N line connection terminal 144 of the motor terminal block, connect the Hall and black transformer plug and the motor black transformer socket 137, and then cover the three-phase small cover 15. Open the motor end cover 134, connect the motor three-phase line 139 to the motor three-phase terminal 141, and electrically connect the motor N line 138 to the equipotential point of the battery pack and the junction point of the three-phase winding of the motor. The entire circuit connection is completed, and the motor end cover 134 is installed. At this point, the integrated controller and its electric assembly are assembled.
