[0036] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0037] In the description of the present utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection of two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.
[0038] In the following description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present invention, and they themselves have no specific meaning. Therefore, "module" and "component" can be used interchangeably.
[0039] See also Figures 1 to 3 As shown, the utility model discloses an integrated power component, including a housing 1, a capacitor module 2, a power module 3, and a three-phase component.
[0040] The housing 1 includes a main body 11 and a limiting portion 12 . The limiting portion 12 is vertically disposed to the bottom surface of the main body 11 and forms a limiting area with the bottom surface of the main body 11 . The capacitor module 2 is disposed in the limiting area.
[0041] The top surface of the main body 11 is recessed to form a heat dissipation water channel 13, which includes a water inlet end and a water outlet end connected to each other. The water inlet end and the water outlet end are respectively connected to the outside of the main body, and the heat dissipation water channel 13 covers the limiting area in the vertical direction.
[0042] Specifically, the main body 11 can be set to be approximately rectangular, and a heat dissipation channel 13 is formed in the groove sunken in the top surface of the main body 11, and the limiting portion 12 surrounds the bottom surface of the main body 11 to form a limiting area 3. The heat dissipation channel 13 is set along the length direction and width direction of the main body 11. The width and length of the heat dissipation channel are slightly smaller than the length and width of the main body 11. The water inlet end and the water outlet end at both ends are connected and extend out of the main body 1 respectively to allow the heat dissipation liquid to enter and flow out. After the above arrangement, the upper heat dissipation surface of the heat dissipation channel 13 contacts the power module 3, and the lower heat dissipation surface of the heat dissipation channel 13 is close to the capacitor module 2, so that the power module 3 and the capacitor module 2 can be integrated into one component, and the heat dissipation area of the heat dissipation channel 13 is fully utilized, the longitudinal space is reasonably used, and the occupation of the lateral space is reduced.
[0043] The power module 3 is arranged above the housing 1 , and the power module 3 covers the heat dissipation channel 13 in the vertical direction. One side of the power module 3 is connected to the capacitor module 2 via a DC terminal 32 , and the other side of the power module 3 is provided with a three-phase AC terminal 31 .
[0044] The three-phase assembly includes a three-phase copper busbar 41 and a mounting seat 42 . The mounting seat 42 is recessed with a mounting groove 425 . The three-phase AC terminal 31 is inserted into the mounting groove 425 . The three-phase copper busbar 41 covers the three-phase AC terminal 31 in the mounting groove 425 and is connected to the three-phase AC terminal 31 .
[0045] Specifically, when the power module is used in the motor controller, the AC side of the power module needs to be connected to the motor through a three-phase copper busbar so that the three-phase AC current output by the power module reaches the motor and controls the motor. The three-phase copper busbar is usually installed on the housing of the motor controller, making the size chain from the motor to the housing of the motor controller and then to the power module longer.
[0046] See also Figure 2 As shown, in this embodiment, the integrated power component is provided with a mounting seat 42 on the AC side of the power module 3, and the top surface of the mounting seat 42 is recessed to form a mounting groove 425, and the three-phase AC terminal 31 of the power module 3 is inserted into the mounting groove 425, and the three-phase copper busbar 41 is stacked above the three-phase AC terminal 31, and the three-phase AC terminal 31 is connected to the three-phase copper busbar 41. Through the arrangement of the above-mentioned three-phase component, the three-phase copper busbar can also be integrated on the integrated power component of this embodiment, reducing the tolerance accumulation from the housing of the motor controller to the power component, reducing the dimension chain, and better ensuring the accuracy of the assembly of the AC terminal of the power module.
[0047] It can be understood that the three-phase AC terminal is divided into a U-phase AC terminal, a V-phase AC terminal, and a W-phase AC terminal, so the mounting seat 42 is provided with a U-phase mounting groove, a V-phase mounting groove, and a W-phase mounting groove corresponding to the AC terminals of different phases. The U-phase AC terminal is inserted into the U-phase mounting groove, and the U-phase copper bar is covered above the U-phase AC terminal to connect the U-phase copper bar to the U-phase AC terminal, and so on, to achieve the connection between the AC terminals of different phases and the copper bar.
[0048] In an alternative embodiment, see Figure 2 As shown, the mounting seat 42 is provided with a first threaded column 421 protruding downward below the mounting groove 425, the three-phase copper bar 41 is provided with a first three-phase copper bar through hole 411, the three-phase AC terminal 31 is provided with an AC terminal through hole 311, and the first three-phase copper bar through hole 411, the AC terminal through hole 31 and the first threaded column 421 overlap in the vertical direction. The first fixing screw penetrates the first three-phase copper bar through hole 411, the AC terminal through hole 31 and the first threaded column 421 from top to bottom, so as to fix the three-phase copper bar 41, the three-phase AC terminal 31 and the mounting seat 42.
[0049] Specifically, the first fixing screw penetrates the first three-phase copper busbar through hole 411 and the AC terminal through hole 31 from top to bottom, so that the three-phase copper busbar 41 and the AC terminal 31 are mounted outside the first fixing screw from top to bottom; and, since the first threaded column 421 is located below the mounting groove 425, when the bottom of the first fixing screw is inserted into the first threaded column 421, the three-phase copper busbar 41 and the AC terminal 31 can be fixed in the mounting groove 425 in the vertical direction, and the three-phase copper busbar 41 is fitted above the AC terminal 31, so that the three-phase copper busbar 41 and the AC terminal 31 are connected.
[0050] In an alternative embodiment, see Figure 2 As shown, a second three-phase copper bar through hole 412 is opened on the three-phase copper bar 41, and a limiting column 422 is set in the mounting groove 425 of the mounting seat 42. The limiting column 422 is inserted into the second three-phase copper bar through hole 412 in the vertical upward direction and partially exposed outside the three-phase copper bar 41.
[0051] It can be understood that the limiting column 422 passes through the second three-phase copper bar through hole 412. When the three-phase copper bar is subjected to horizontal force, the limiting column 422 will limit the three-phase copper bar 41 through the second three-phase copper bar through hole 412 to prevent the three-phase copper bar 41 from loosening or displacement in the installation groove 425.
[0052] In an alternative embodiment, see Figure 2As shown, the mounting seat 42 is provided with a latch 423 on the inner side of the mounting groove 425 , and the end of the latch 423 is bent toward the mounting groove 425 and fits with the upper surface of the three-phase copper busbar 41 .
[0053] In an optional embodiment, at least one second threaded column 111 protruding upward is provided on the top surface of the main body 11 on one side outside the heat dissipation water channel 13 and close to the mounting seat 42, and a mounting seat through hole 424 is opened on the mounting seat 42, and the mounting seat through hole 424 and the second threaded column 111 overlap in the vertical direction;
[0054] The second fixing screw passes through the mounting seat through hole 424 and the second threaded column 111 from top to bottom, so as to fix the mounting seat 42 and the main body 11 .
[0055] In an alternative embodiment, see Figure 2 As shown, the limiting portion 12 is arranged along both sides of the width direction and any side of the length direction of the heat dissipation water channel 13 to form a circumferential side wall and a limiting opening of the limiting area.
[0056] A plurality of DC terminals 32 are arranged on one side of the power module 3 close to the limiting opening, and a capacitor copper bus 21 bent along the side of the capacitor module 2 toward the top surface of the main body 11 is arranged on one side of the capacitor module 2 close to the limiting opening, and the capacitor copper bus 21 is connected to the plurality of DC terminals 32 by laser welding.
[0057] It is understandable that the capacitor copper busbar 21 and the DC terminal 32, which are bent toward the top surface of the main body 11, can be directly attached and connected by laser welding. The laser welding connection method forms a covalent bond between the materials, which is more reliable and has no contact resistance, and increases the longitudinal stacking of the capacitor copper busbar 21 and the DC terminal 32, which can reduce the stray inductance of the power system.
[0058] Preferably, if Figure 3 As shown, a plurality of capacitor copper bar through holes 211 are provided on the side of the capacitor copper bar 21 close to the capacitor module 2 .
[0059] It can be understood that since the capacitor copper bar 21 is bent toward the top surface of the main body 11, the area of the portion of the capacitor copper bar led out from the capacitor module 2 is increased. By opening a plurality of capacitor copper bar through holes 211 on the side of the capacitor copper bar 21 close to the capacitor module 2, the material used for the capacitor copper bar 21 can be reduced, and at the same time, the stress generated by the bending setting of the capacitor copper bar 21 can be reduced, thereby enhancing the stability of the capacitor copper bar 21.
[0060] In an optional embodiment, a sealing groove 14 is formed on the top surface of the main body 11 around the outer edge of the heat dissipation water channel 13 and circumferentially matches the bottom of the power module 3. A sealing member 15 is arranged in the sealing groove 14. The thickness of the sealing member 15 is greater than the height of the sealing groove 14, so that when the power module 3 covers the heat dissipation water channel 13 in the vertical direction, the sealing member 15 produces elastic deformation, and a seal is formed between the power module 3 and the heat dissipation water channel 13.
[0061] like Figures 4 to 5 As shown, the utility model also discloses a motor controller 5, including an electric control housing 51 with an upward opening, wherein a DC filter component 52 and the aforementioned integrated power component are connected to each other and disposed in the electric control housing 51, a drive control board 53 is disposed above the integrated power component, and a shielding board 54 is disposed between the drive control board 53 and the DC filter component 52. It can be understood that the shielding board 54 realizes electromagnetic isolation between the DC filter component 52 and the drive control board 53.
[0062] The electric control housing 51 is provided with a water inlet 55 and a water outlet 56 connected to the outside of the electric control housing 51 . The water inlet 55 is connected to the water inlet end, and the water outlet 56 is connected to the water outlet end, so that the heat dissipation water channel 14 is connected to the outside of the electric control housing 51 .
[0063] Specifically, the water inlet 55 is connected to the water inlet end, and the water outlet 56 is connected to the water outlet end, so that the water inlet 55 to the heat dissipation water channel 13 to the water outlet 56 are connected, and the water inlet 55 and the water outlet 56 are respectively connected to the outside of the electronic control housing 51. The water inlet 55 can be externally connected to a liquid inlet device, and the water outlet 56 can be externally connected to a liquid outlet device, so that the heat dissipation liquid enters the heat dissipation water channel 13 through the water inlet 55 and then flows out through the water outlet 56, thereby realizing heat dissipation of the power module 3 and the capacitor module 2.
[0064] A shielding wall 57 is disposed in the electric control housing 51 along the outer edge of the integrated power component, and the shielding wall 57 extends to the bottom of the shielding plate 54 .
[0065] It can be understood that the shielding wall 57 is arranged along the outer edge of the integrated power component to achieve electromagnetic isolation of the integrated power component in the electric control housing 51. At the same time, since the shielding wall 57 extends to the bottom of the shielding plate 54, the edge of the shielding wall 57 is connected to the edge of the shielding plate 54 in the projection direction. The high-voltage area and the low-voltage area of the drive control board located above the shielding plate 54 can be respectively arranged on the side close to the DC filter component and the side close to the integrated power component, and the edge of the shielding wall 57 and the edge of the shielding plate 54 jointly electromagnetically isolate the high-voltage area and the low-voltage area of the drive control board.
[0066] like Figure 6As shown, the utility model also discloses an electric bridge assembly, including a motor 6 and the motor controller 5 as described above, wherein the lower end cover of the motor 6 cooperates with the upper end surface of the motor controller 5 so that the motor 6 and the motor controller 5 are closed opposite to each other.
[0067] Specifically, in the existing bridge assembly, the motor controller and the motor are usually closed separately before being connected. In the utility model, the upper end surface of the motor controller is combined with the lower end cover of the motor, and the upper end surface of the motor controller is used as the lower cover of the motor. Based on this, the use of the upper cover of the motor controller and the lower cover of the motor is omitted. In addition, since the motor controller is installed in the axial direction of the motor, the vertical height of the bridge assembly can be effectively reduced, the structure is more compact, and the power density is higher.
[0068] It should be noted that the embodiments of the present invention have better practicability and do not impose any form of limitation on the present invention. Any technician familiar with the field may use the technical content disclosed above to change or modify it into an equivalent effective embodiment. However, any modification or equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
