DETAILED DESCRIPTION

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0035] Combine the following Figure 1-Figure 8 An electric power assembly 100 and a vehicle 1000 having the electric power assembly 100 according to an embodiment of the present invention will be described in detail.

[0036] Reference Figure 1-Figure 3 As shown, the electric assembly 100 according to the embodiment of the present invention may include a first housing 40 .

[0037] Among them, refer to Figure 1 , Figure 3 As shown, the first housing 40 includes a motor housing 4012 and an electric control housing 4013, and the motor housing 4012 and the electric control housing 4013 are fixedly connected in a first direction. Figure 1 , Figure 3 In the F1-F2 direction, the motor housing 4012 and the electric control housing 4013 are connected. Specifically, the electric control housing 4013 is connected to the F1 side of the motor housing 4012.

[0038] Optionally, the projection of the electric control housing 4013 in a plane perpendicular to the first direction is within the projection range of the motor housing 4012 in a plane perpendicular to the first direction. In this way, the outer contour envelope size of the projection of the electric control housing 4013 in a plane perpendicular to the first direction does not exceed the envelope size of the motor housing 4012 in a plane perpendicular to the first direction. Therefore, the arrangement of the electric control housing 4013 does not increase the envelope size of the electric assembly 100 in a plane perpendicular to the first direction, so that the electric assembly 100 has a compact structure and occupies a small space.

[0039] Alternatively, in the projection in the plane perpendicular to the first direction, the electric control housing 4013 protrudes from the motor housing 4012, and the size of the protruding portion does not exceed 20 mm. In other words, the size of the projection of the electric control housing 4013 in the plane perpendicular to the first direction protrudes from the projection range of the motor housing 4012 in the plane does not exceed 20 mm. For example, the size of the protruding portion can be 5 mm, 10 mm, 15 mm, 20 mm, etc., and can also be other values ​​not exceeding 20 mm, which are not listed here one by one.

[0040] In this way, during the design phase, the size of the motor housing 4012 is used as a design reference for the motor controller, making the structure of the electric assembly 100 as compact as possible, making full use of the special-shaped space on the outer circumference of the motor housing 4012, and making the integration of the motor and the electronic control higher.

[0041] According to the electric assembly 100 of the embodiment of the present invention, by setting the projection of the electric control housing 4013 in the plane perpendicular to the first direction to be within the projection range of the motor housing 4012 in the plane, or setting the projection of the electric control housing 4013 in the plane perpendicular to the first direction to protrude beyond the projection range of the motor housing 4012 in the plane by no more than 20 mm, the setting of the electric control housing 4013 will not significantly increase the envelope size of the electric assembly 100 in the plane perpendicular to the first direction; thus, the electric control housing 4013 will not occupy too much extra space, and the special-shaped space of the electric assembly 100 is fully utilized, thereby achieving the effect of improving the space utilization rate of the electric assembly 100 and making the electric assembly 100 compact.

[0042] The electric assembly 100 may further include a transmission housing 90 and an electric control cover 50. The transmission housing 90 is fixedly connected to the first housing 40 in a second direction, and the second direction intersects the first direction. Figure 1 , Figure 3 In the F3-F4 direction, the transmission housing 90 is connected to the first housing 40, specifically, the transmission housing 90 is connected to the F4 side of the first housing 40. A motor shaft is disposed inside the motor housing 4012, and the second direction is parallel to the axial direction of the motor shaft inside the motor housing 4012. The angle between the first direction and the second direction can range from 45° to 90°, for example, the angle between the first direction and the second direction can be 60°, 75°, 90°, etc. Of course, the angle between the first direction and the second direction can also be other values ​​between 45° and 90°, which are not listed here one by one.

[0043] In some embodiments, the first direction, the second direction, and the third direction are perpendicular to each other.

[0044] It should be noted that, in the present invention, when referring to the outline of the electric control housing 4013, only the sum of the side walls of the electric control housing 4013 used to enclose the internal installation space is included, and additional structures such as the mounting seat 40131 and the connector on the electric control housing 4013 are not included. Figure 1 , Figure 3In the embodiment, the electric control housing 4013 includes a first side wall, a second side wall and a third side wall, the first side wall and the third side wall are arranged opposite to each other, the second side wall connects the first side wall and the third side wall, the second side wall is arranged opposite to the transmission housing 90, and the first side wall is provided with a housing side opening 407. The first side wall, the second side wall and the third side wall are vertically extending side walls, and the "projection of the electric control housing 4013 in a plane perpendicular to the first direction" refers to the projection of the outer surface of the first side wall, the second side wall and the third side wall in a plane perpendicular to the first direction, and does not include the horizontally arranged mounting seat 40131 on the second side wall.

[0045] The electric control cover plate 50 and the electric control housing 4013 are fixedly connected at one end away from the motor housing 4012. Specifically, the electric control housing 4013 has a cover plate mounting surface 4011 at one end away from the motor housing 4012, and the electric control cover plate 50 is suitable for being mounted on the cover plate mounting surface 4011. The electric control components mounted on the electric control cover plate 50 are far away from the motor body mounted in the motor housing 4012, which is conducive to reducing the interference of the electric control components on the motor body.

[0046] After the transmission housing 90 is connected to the first housing 40 , a special-shaped recessed area is formed, and the electric control cover plate 50 is installed in the special-shaped recessed area.

[0047] Optionally, in the first direction, an absolute value of a difference between a dimension of the electric control cover 50 protruding from the first housing 40 and a dimension of the transmission housing 90 protruding from the first housing 40 does not exceed 40 mm.

[0048] That is, in the first direction, the electric control cover plate 50 and the transmission housing 90 both protrude from the first housing 40, and the absolute value of the difference between the dimensions of the electric control cover plate 50 and the transmission housing 90 protruding from the first housing 40 does not exceed 40 mm. In this way, the outer contour envelope dimension of the electric control cover plate 50 in the first direction is slightly different from the outer contour envelope dimension of the transmission housing 90 in the first direction, so that the electric assembly 100 has a compact structure and occupies a small space.

[0049] In some optional embodiments, the dimension of the electric control cover plate 50 protruding from the first housing 40 is not greater than the dimension of the transmission housing 90 protruding from the first housing 40. In other words, in the first direction, both the electric control cover plate 50 and the transmission housing 90 protrude from the cover plate mounting surface 4011, and the dimension of the electric control cover plate 50 protruding from the cover plate mounting surface 4011 is not greater than the dimension of the transmission housing 90 protruding from the cover plate mounting surface 4011.

[0050] In some other optional embodiments, the dimension of the transmission housing 90 protruding from the first housing 40 is not greater than the dimension of the electric control cover plate 50 protruding from the first housing 40. In other words, in the first direction, both the electric control cover plate 50 and the transmission housing 90 protrude from the cover plate mounting surface 4011, and the dimension of the transmission housing 90 protruding from the cover plate mounting surface 4011 is not greater than the dimension of the electric control cover plate 50 protruding from the cover plate mounting surface 4011.

[0051] Optionally, in the first direction, the absolute value of the difference between the size of the electric control cover 50 protruding from the first housing 40 and the size of the transmission housing 90 protruding from the first housing 40 can be 0mm, 10mm, 15mm, 20mm, 24mm, 30mm, 35mm, 40mm, etc. Of course, the absolute value of the size difference can also be other values ​​between 0mm and 40mm, which are not listed here one by one.

[0052] Reference Figure 1 As shown, the first direction is the F1-F2 direction, that is, Figure 1 In the up-down direction, the absolute value of the difference between the height of the electric control cover 50 protruding upward from the first housing 40 and the height of the transmission housing 90 protruding upward from the first housing 40 does not exceed 40 mm. In other words, the absolute value of the difference between the highest point of the electric control cover 50 and the highest point of the transmission housing 90 does not exceed 40 mm. In this way, the maximum heights of the electric control cover 50 and the transmission housing 90 limit the maximum height of the electric assembly 100, and the installation of the electric control cover 50 on the first housing 40 will not significantly change the maximum height dimension of the electric assembly 100.

[0053] The projections of the electric control housing 4013 and the electric control cover plate 50 in the plane perpendicular to the first direction are both located within the projection range of the motor housing 4012 in the plane perpendicular to the first direction. In this way, the outer contour envelope size of the projections of the electric control housing 4013 and the electric control cover plate 50 in the plane perpendicular to the first direction does not exceed the envelope size of the motor housing 4012 in the plane perpendicular to the first direction. Therefore, the arrangement of the electric control cover plate 50 and the electric control housing 4013 does not increase the envelope size of the electric assembly 100 in the plane perpendicular to the first direction, so that the electric assembly 100 has a compact structure and occupies a small space.

[0054] In some embodiments of the present invention, the cover plate mounting surface 4011 is located on a plane perpendicular to the first direction. In this way, the projections of the electric control cover plate 50 and the electric control housing 4013 in the plane where the cover plate mounting surface 4011 is located are located within the projection range of the motor housing 4012 in the plane where the cover plate mounting surface 4011 is located. Therefore, the arrangement of the electric control cover plate 50 and the electric control housing 4013 will not increase the envelope size of the electric assembly 100 in the plane where the cover plate mounting surface 4011 is located.

[0055] Reference Figure 1 As shown, the F3-F4 direction is perpendicular to the F1-F2 direction, the F5-F6 direction is perpendicular to the F1-F2 direction, the F5-F6 direction is perpendicular to the F3-F4 direction, the dimension of the electric assembly 100 in the F1-F2 direction is the height dimension, the dimension in the F3-F4 direction is the length dimension, and the dimension in the F5-F6 direction is the width dimension. The "plane perpendicular to the first direction" is the plane formed by F3-F4-F5-F6, and the projection of the electric control housing 4013 and the electric control cover plate 50 in the plane is located within the projection range of the motor housing 4012 in the plane. In this way, in the plane perpendicular to the first direction, the envelope boundary of the electric control housing 4013 and the electric control cover plate 50 does not exceed the envelope boundary of the motor housing 4012, and the installation of the electric control housing 4013 and the electric control cover plate 50 on the motor housing 4012 will not change the maximum length dimension and the maximum width dimension of the electric assembly 100.

[0056] Optionally, the electric control cover plate 50 may be an aluminum alloy housing, a steel housing, etc., and the first housing 40 may be an aluminum alloy housing, a steel housing, etc.

[0057] In the related art, the electric assembly generally includes a motor, a motor controller and a transmission. The motor, the motor controller and the transmission are generally independently assembled components. The three are then assembled together, which makes the overall layout inflexible, resulting in unreasonable spatial arrangement, which in turn leads to a larger volume of the electric assembly. When the motor controller is installed on the motor, at least one of the height, length and width of the overall structure of the electric assembly will increase significantly, which will result in a low space utilization rate of the electric assembly. According to the electric assembly 100 of the embodiment of the present invention, the motor housing 4012 is fixedly connected to the electronic control housing 4013 in the first direction, and the transmission housing 90 is fixedly connected to the first housing 40 in the second direction, so that the spatial arrangement of the electric assembly 100 is reasonable and the structure is compact. By setting the absolute value of the difference between the dimensions of the electric control cover plate 50 and the transmission housing 90 protruding from the first housing 40 in the first direction to no more than 40 mm, the outer contour envelope dimension of the electric control cover plate 50 in the first direction is slightly different from the outer contour envelope dimension of the transmission housing 90 in the first direction, and the setting of the electric control cover plate 50 will not affect the envelope dimension of the electric assembly 100 in the first direction too much; by setting the electric control cover plate 50 and the electric control housing 4013 so that their projections in a plane perpendicular to the first direction are within the projection range of the motor housing 4012 in the plane, the setting of the electric control cover plate 50 and the electric control housing 4013 will not increase the envelope dimension of the electric assembly 100 in the plane perpendicular to the first direction; thus, the electric control cover plate 50 will not occupy too much extra space, and the special-shaped space of the electric assembly 100 is fully utilized, thereby achieving the effect of improving the space utilization rate of the electric assembly 100 and making the electric assembly 100 compact.

[0058] In some embodiments of the present invention, in the first direction, the absolute value of the difference between the size of the electric control cover plate 50 protruding from the first housing 40 and the size of the transmission housing 90 protruding from the first housing 40 does not exceed 30 mm. As a result, the outer contour envelope size of the electric control cover plate 50 in the first direction is smaller than the outer contour envelope size of the transmission housing 90 in the first direction, and the setting of the electric control cover plate 50 will not affect the envelope size of the electric assembly 100 in the first direction too much. Optionally, in the first direction, the absolute value of the difference between the size of the electric control cover plate 50 protruding from the first housing 40 and the size of the transmission housing 90 protruding from the first housing 40 can be 0 mm, 5 mm, 14 mm, 22 mm, 25 mm, 30 mm, etc. Of course, the absolute value of the size difference can also be other values ​​between 0 mm and 30 mm, which are not listed here one by one.

[0059] In some embodiments of the present invention, Figure 1 , Figure 3 As shown, the first housing 40 is provided with a transmission shaft hole 406, which is provided on the electronic control housing 4013. The first housing 40 is also provided with a motor shaft hole 405, which is provided on the motor housing 4012. The transmission shaft hole 406 is used to install the transmission shaft 91 of the transmission, and the transmission shaft 91 is rotatably installed in the transmission shaft hole 406; the motor shaft hole 405 is used to install the motor shaft of the motor body, and the motor shaft is rotatably installed in the motor shaft hole 405.

[0060] Optionally, the motor housing 4012 may include a housing body and an end cover, and the motor shaft hole 405 may be opened on the end cover.

[0061] In some embodiments of the present invention, reference Figure 2-Figure 3 As shown, a hollow sleeve 408 is provided in the electronic control housing 4013, the end of the sleeve 408 is connected to the transmission shaft hole 406, and the transmission shaft 91 is passed through the sleeve 408. Therefore, the sleeve 408 can protect the transmission shaft 91 and prevent the transmission shaft 91 from interfering with other parts in the electronic control housing 4013 when rotating. Optionally, the axial direction of the sleeve 408 can be the same as the second direction.

[0062] In some embodiments of the present invention, reference Figure 1-Figure 3 and Figure 6A capacitor installation area is formed in the electric control housing 4013. The capacitor installation area is used to install the capacitor assembly 30. The capacitor assembly 30 is installed in the capacitor installation area. In this way, the capacitor assembly 30 is arranged inside the electric control housing 4013, and is no longer arranged on the electric control cover 50, so that the volume of the electric control cover 50 can be smaller, and other electric control components can be arranged on the electric control cover 50, thereby improving the space utilization rate inside the electric control cover 50. The capacitor installation area is located between the motor housing 4012 and the electric control cover 50, and the capacitor installation area is located on one side of the transmission shaft hole 406. Figure 1 , Figure 3 As shown, the capacitor installation area is located on the F6 side of the transmission shaft hole 406, and the capacitor assembly 30 is installed in the capacitor installation area, so that the capacitor assembly 30 is located between the motor housing 4012 and the electric control cover plate 50, that is, the capacitor assembly 30 is located between the motor shaft hole 405 and the electric control cover plate 50, that is, the capacitor assembly 30 is located in the space between the electric control cover plate 50 and the motor shaft, and the capacitor assembly 30 is closer to the electric control cover plate 50 than the motor shaft, so that it is convenient for the capacitor assembly 30 to be connected with the electric control assembly installed on the electric control cover plate 50. At the same time, there is a certain distance between the electric control assembly installed on the electric control cover plate 50 and the capacitor assembly 30, and the heat of the capacitor assembly 30 will not interfere too much with the electric control assembly at the electric control cover plate 50, which is beneficial to the heat dissipation of the capacitor assembly 30 and the heat dissipation of the electric control assembly at the electric control cover plate 50. At the same time, the capacitor assembly 30 is located on one side of the transmission shaft hole 406, so that the capacitor assembly 30 can make full use of the side space of the transmission shaft hole 406, and does not interfere with the transmission shaft 91 installed at the transmission shaft hole 406, thereby improving the space utilization rate inside the first housing 40. In addition, the outer peripheral portion of the motor housing 4012 can be used to support the fixed capacitor assembly 30.

[0063] In some embodiments of the present invention, reference Figure 1 , Figure 3 As shown, the electric control housing 4013 is provided with a housing side opening 407, and the housing side opening 407 is connected to the capacitor installation area. The capacitor assembly 30 can enter and exit the capacitor installation area through the housing side opening 407, thereby facilitating the installation, removal and maintenance of the capacitor assembly 30 in the electric control housing 4013. The electric assembly 100 also includes a housing cover 402, which is used to cover or open the housing side opening 407. Specifically, when the housing cover 402 opens the housing side opening 407, it is convenient to install, remove or repair the capacitor assembly 30 through the housing side opening 407; when the housing cover 402 covers the housing side opening 407, the housing cover 402 can protect the capacitor assembly 30.

[0064] Optionally, the housing cover 402 and the electric control housing 4013 may be detachably connected and fixed by threaded fasteners (such as bolts, screws, etc.), so that when the housing side opening 407 needs to be opened, the threaded fasteners only need to be removed, and the housing cover 402 can be removed from the electric control housing 4013 to expose the housing side opening 407. When the housing side opening 407 needs to be sealed, the threaded fasteners only need to be inserted through the housing cover 402 and the electric control housing 4013 at the same time, and the housing cover 402 can be fixed to the electric control housing 4013, so that the housing cover 402 seals the housing side opening 407.

[0065] Alternatively, the housing cover 402 and the electric control housing 4013 may be pivotally connected at one end. Specifically, the first end of the housing cover 402 is hingedly connected to the electric control housing 4013, and a first locking structure is provided between the second end of the housing cover 402 and the electric control housing 4013. Thus, when it is necessary to open the housing side opening 407, it is only necessary to unlock the first locking structure and rotate the housing cover 402, so that the housing cover 402 can be opened to a certain angle to expose the housing side opening 407. When it is necessary to cover the housing side opening 407, it is only necessary to rotate the housing cover 402 in the opposite direction to close the housing cover 402, and the first locking structure can be used to lock the second end of the housing cover 402 and the electric control housing 4013, so that the housing cover 402 covers the housing side opening 407.

[0066] In some embodiments of the present invention, the wall thickness of the housing cover 402 is thinner than the wall thickness of the electric control housing 4013. In this way, the housing cover 402 is thinner, and the heat generated by the capacitor assembly 30 during operation is easily dissipated to the external environment through the housing cover 402, which is beneficial to the heat dissipation of the capacitor assembly 30, and is also beneficial to saving the material of the electric control housing 4013, reducing the weight of the electric control housing 4013, and realizing a lightweight design.

[0067] In some embodiments of the present invention, in the third direction, the housing cover 402 protrudes from the electric control housing 4013, but does not protrude from the motor housing 4012, the third direction, the first direction and the second direction intersect, and the third direction is different from the first direction and the second direction. Figure 1 , Figure 3In the third direction, the third direction is the F5-F6 direction. In the F6 direction, the size of the housing cover 402 protruding from the electric control housing 4013 is not greater than the size of the motor housing 4012 protruding from the electric control housing 4013. In other words, the size of the housing cover 402 protruding toward the F6 side is not greater than the size of the motor housing 4012 protruding toward the F6 side. In this way, the outer contour envelope size of the housing cover 402 in the third direction does not exceed the outer contour envelope size of the motor housing 4012. Therefore, the provision of the housing cover 402 will not increase the outer contour envelope size of the electric assembly 100 in the third direction, and will not increase the occupied space of the first housing 40 in the F5-F6 direction.

[0068] In some embodiments of the present invention, the side wall of the electric control housing 4013 is retracted inwardly in the F5 direction relative to the side wall of the motor housing 4012. Figure 1 , Figure 3 As shown, the electric control housing 4013 is connected to the F1 side of the motor housing 4012, and the side wall of the electric control housing 4013 is retracted in the F5 direction relative to the side wall of the motor housing 4012, and the housing side opening 407 is provided on the side wall of the electric control housing 4013 that is retracted in the F5 direction. In this way, a retracted space is formed on the F6 side of the electric control housing 4013, providing space for the installation of the housing cover 402. After the electric assembly 100 is installed on the vehicle 1000, the retracted space can also provide a space for other components of the vehicle 1000 to avoid.

[0069] In one embodiment, the outer dimensions of the electric control cover plate 50 are approximately: 261mm×246mm×64mm. The electric control cover plate 50 is installed on the first shell 40. The outer periphery of the electric control cover plate 50 does not exceed the outer periphery of the first shell 40, and the height of the electric control cover plate 50 is approximately 24mm lower than the first shell 40.

[0070] In some embodiments of the present invention, reference Figure 1 , Figure 3 and Figure 7 As shown, the electric control housing 4013 has a housing accommodating cavity 403, and the capacitor installation area can be a part of the housing accommodating cavity 403. The electric assembly 100 includes an electric control component, and the electric control component is at least partially arranged in the housing accommodating cavity 403. In this way, the electric control component can utilize the internal space of the first housing 40, so that the layout is reasonable.

[0071] In some embodiments of the present invention, reference Figure 1 , Figure 3 and Figure 7 As shown, the electric control cover plate 50 also has a cover plate through hole 506 , which is connected to the housing accommodating cavity 403 . The cover plate through hole 506 is used to connect the electric control component installed on the electric control cover plate 50 with the structure installed in the first housing 40 .

[0072] In some embodiments of the present invention, reference Figure 1 , Figure 3 As shown, the electric control housing 4013 has a housing end opening 404, the housing end opening 404 is connected to the housing accommodating cavity 403, the cover plate mounting surface 4011 is arranged on the outer periphery of the housing end opening 404, and the cover plate through hole 506 is connected to the housing end opening 404. Figure 3 As shown, the cover plate installation surface 4011 is a full-circle annular structure surrounding the outer circumference of the shell end opening 404, so that when the electric control cover plate 50 is installed on the cover plate installation surface 4011, the electric control cover plate 50 can completely cover the shell end opening 404 to prevent the shell end opening 404 from being exposed.

[0073] In some embodiments of the present invention, the electric control cover plate 50 includes a cover plate body 503, which is suitable for being installed on the electric control housing 4013, specifically installed on the cover plate installation surface 4011, and has an electric control cavity in the cover plate body 503, which is connected to the housing accommodating cavity 403, and at least part of the electric control components are installed in the electric control cavity. The cover plate through hole 506 is connected to the electric control cavity and the housing end opening 404, so that the electric control cavity is connected to the housing accommodating cavity 403. In other words, the electric control cavity is connected to the housing accommodating cavity 403 through the cover plate through hole 506 and the housing end opening 404.

[0074] Optionally, the cover body 503 and the electric control housing 4013 may be connected and fixed in a detachable manner using threaded fasteners (such as bolts, screws, etc.), or may be connected and fixed in an irremovable manner using rivets, bonding, welding, etc.

[0075] In some embodiments of the present invention, the electric control cover plate 50 further includes a small cover 502, and the small cover 502 is used to open or cover the opening of the electric control cavity at one end away from the electric control housing 4013. Figure 1 , Figure 3 The small cover 502 is used to open or cover the upper cavity opening of the electric control cavity.

[0076] Optionally, the small cover 502 and the cover body 503 can be detachably connected and fixed using threaded fasteners (such as bolts, screws, etc.), which facilitates the subsequent disassembly of the small cover 502 to install, disassemble, and repair the internal modules of the cover body 503.

[0077] Or optionally, the first end of the small cover 502 is hingedly connected to the cover body 503, and a second locking structure is provided between the second end of the small cover 502 and the cover body 503. When it is necessary to open the cavity opening of the electric control cavity, the second locking structure is unlocked and the small cover 502 is rotated to expose the cavity opening of the electric control cavity; when it is necessary to seal the cavity opening of the electric control cavity, the small cover 502 is rotated in the opposite direction and the second locking structure is used to lock the second end of the small cover 502 and the cover body 503 so that the small cover 502 seals the cavity opening of the electric control cavity.

[0078] In some embodiments of the present invention, the electric control assembly includes a capacitor assembly 30 and a power assembly 10, the capacitor assembly 30 and the power assembly 10 are fixedly connected, and the power assembly 10 is fixedly connected to the electric control cover plate 50; the electric control housing 4013 has a housing accommodating cavity 403, and the capacitor assembly 30 is fixedly installed in the housing accommodating cavity 403. As a result, the motor controller is quickly assembled, and the power assembly 10 and the electric control cover plate 50 are first assembled and then fixed to the electric control housing 4013 as a whole. The assembly of the power assembly 10 and the electric control cover plate 50 and the capacitor assembly 30 can be assembled to the electric control housing 4013 at the same time, which is conducive to improving assembly efficiency.

[0079] In some embodiments of the present invention, reference Figure 1-Figure 3 , the electric control cover plate 50 has an opening 507, and the opening 507 is aligned with the connection between the capacitor assembly 30 and the power assembly 10. Optionally, the electric control cover plate 50 includes a small cover 502, and the small cover 502 can be directly installed on the electric control housing 4013, or indirectly installed on the electric control housing 4013 through the cover plate body 503, and the opening 507 is set on the small cover 502. Through the opening 507, the capacitor assembly 30 and the power assembly 10 can be connected and disassembled, and the operation is convenient. In the assembly process of the electric assembly 100, the power assembly 10 can be installed on the electric control cover plate 50 first, and the capacitor assembly 30 can be installed on the electric control housing 4013, and then the capacitor assembly 30 and the power assembly 10 are connected through the opening 507. In this way, the assembly of the power assembly 10 with the electric control cover plate 50, and the assembly of the capacitor assembly 30 with the electric control housing 4013 can be completed simultaneously on different assembly lines, which is conducive to saving assembly man-hours. Similarly, during the disassembly of the electric assembly 100, the capacitor assembly 30 and the power assembly 10 can be disassembled through the opening 507 first, and after the electric control cover 50 is removed from the electric control housing 4013, the power assembly 10 and the electric control cover 50, and the capacitor assembly 30 and the electric control housing 4013 can be disassembled simultaneously on different disassembly lines, which is conducive to saving disassembly time.

[0080] In some embodiments of the present invention, the electric control cover plate 50 further includes a protective cover 501 , and the protective cover 501 is used to cover or open the opening 507 .

[0081] When the electric control cover 50 includes a cover body 503, and an electric control cavity is provided in the cover body 503, the power component 10 can be arranged in the electric control cavity, and the capacitor component 30 is installed in the shell accommodating cavity 403. The small cover 502 has an opening 507 connected to the electric control cavity, and the power component 10 and the capacitor component 30 are connected or disconnected through the opening 507.

[0082] Of course, in some embodiments, the power component 10 may also be disposed in the housing accommodating cavity 403. That is, the power component 10 is mounted on the electric control cover 50, and the power component 10 is located in the housing accommodating cavity 403.

[0083] In some embodiments of the present invention, the power component 10 is fixedly connected to the electric control cover plate 50, and the power component 10 is arranged on a side of the electric control cover plate 50 close to the first housing 40, and the power component 10 and the electric control cover plate 50 are fixedly connected to the first housing 40 as a whole. In this way, the assembly steps can be simplified and the assembly efficiency can be improved. At the same time, the capacitor component 30 is located in the electric control housing 4013, and the power component 10 is installed on the electric control cover plate 50, so that the space can be reasonably utilized, and the capacitor component 30 is assembled and disassembled through the housing side opening 407, and the assembly and disassembly operations of the power component 10 and the capacitor component 30 do not interfere with each other. When assembling and disassembling the capacitor component 30, it is not necessary to disassemble the power component 10 first, thereby simplifying the assembly and disassembly operations of the electric assembly 100. At the same time, there is a certain distance between the power component 10 and the capacitor component 30, and the heat of the capacitor component 30 will not interfere too much with the power component 10, which is more conducive to the heat dissipation of the power component 10 and the capacitor component 30.

[0084] After the installation of other modules of the electric control housing 4013 and the electric control cover 50 is completed, the small cover 502 is put on, and the screws at the connection between the capacitor component 30 and the power component 10 are installed through the opening 507 set on the small cover 502 to facilitate disassembly and installation operations. When the connection between the capacitor component 30 and the power component 10 is completed, the protective cover 501 is put on to close the outer surface of the electric control cover 50 to reduce the intrusion of external moisture, debris, etc. into the electric control cavity.

[0085] Optionally, threaded fasteners (such as bolts, screws, etc.) can be used to achieve a detachable connection and fixation between the protective cover 501 and the small cover 502, so as to facilitate the subsequent disassembly of the protective cover 501 and install the screws at the connection between the capacitor component 30 and the power component 10 through the opening 507 set on the small cover 502.

[0086] Or optionally, the first end of the protective cover 501 is hingedly connected to the small cover 502, and a third locking structure is provided between the second end of the protective cover 501 and the small cover 502. When it is necessary to open the opening 507, the third locking structure is unlocked and the protective cover 501 is rotated to expose the opening 507; when it is necessary to seal the opening 507, the protective cover 501 is rotated in the opposite direction and the third locking structure is used to lock the second end of the protective cover 501 and the small cover 502 so that the protective cover 501 seals the opening 507.

[0087] The power assembly 10 includes a positive power input terminal 12 and a negative power input terminal 13, and the capacitor assembly 30 includes a positive capacitor output terminal 31 and a negative capacitor output terminal 32. The positive capacitor output terminal 31 is connected to the positive power input terminal 12, and the negative capacitor output terminal 32 is connected to the negative power input terminal 13. The positive capacitor output terminal 31 and the positive power input terminal 12 can be connected or disconnected through the opening 507, and the negative capacitor output terminal 32 and the negative power input terminal 13 can be connected or disconnected through the opening 507.

[0088] In some embodiments of the present invention, reference Figure 4-Figure 6 As shown, the capacitor positive output terminal 31 and the power positive input terminal 12 are both busbars and the two are stacked and overlapped, and the capacitor negative output terminal 32 and the power negative input terminal 13 are both busbars and the two are stacked and overlapped. This can reduce the stray inductance of the power component 10 when it is working, thereby reducing the ripple voltage, improving product reliability and work efficiency, and can reduce the thickness of the output terminal and the corresponding input terminal, making the internal structure of the electric assembly 100 more compact.

[0089] Optionally, the busbar is a copper busbar, that is, the capacitor positive output terminal 31 is a capacitor positive output copper busbar, the power positive input terminal 12 is a power positive input copper busbar, the capacitor negative output terminal 32 is a capacitor negative output copper busbar, the power negative input terminal 13 is a power negative input copper busbar, the capacitor positive output copper busbar is lapped on the power positive input copper busbar, and the capacitor negative output copper busbar is lapped on the power negative input copper busbar. Of course, the busbar can also be an aluminum busbar, a nickel busbar or other conductive busbar, which will not be listed here one by one.

[0090] Reference Figure 4-Figure 5As shown, the capacitor assembly 30 integrates the components such as the positive output terminal 31 of the capacitor, the negative output terminal 32 of the capacitor, the capacitor housing 33, the positive copper bar 34 of the distribution line, the magnetic ring 35 of the distribution connector, the negative copper bar 36 of the distribution line, the baffle 37, the negative copper bar 38 of the DC bus, the positive copper bar 39 of the DC bus, the insurance copper bar 41 of the DC bus connection, the positive fuse 42 of the distribution line, the grounding copper bar 43 of the filter, the capacitor shielding cover 44, the filter capacitor 45, the positive copper bar 46 of the filter, the negative copper bar 47 of the filter, the magnetic ring 48 of the filter, the insurance connection filter copper bar 49, the capacitor core 51, the filter PCB board 52, the positive insurance 53 of the DC bus, etc. Among them, the filter grounding copper bar 43, the filter positive copper bar 46, the filter negative copper bar 47, the filter magnetic ring 48, the filter PCB board 52, the filter capacitor 45, etc. constitute a filter assembly, which is conducive to improving the anti-electromagnetic interference effect of the capacitor assembly 30. The capacitor positive output terminal 31 and the capacitor negative output terminal 32 are both exposed from the capacitor housing 33, and the power positive input terminal 12 and the power negative input terminal 13 are both configured as pins, thereby facilitating the connection between the capacitor positive output terminal 31 and the power positive input terminal 12, and the capacitor negative output terminal 32 and the power negative input terminal 13. The capacitor shielding cover 44 is used to cover the capacitor core 51 to protect the capacitor core 51.

[0091] In some embodiments of the present invention, reference Figure 6-Figure 7 As shown, the electric control assembly further includes a circuit board, which is fixedly connected to the electric control cover plate 50, and the circuit board is arranged on a side of the electric control cover plate 50 close to the first housing 40, and the circuit board, the power assembly 10 and the electric control cover plate 50 are fixedly connected to the first housing 40 as a whole. Thus, the assembly steps can be simplified and the assembly efficiency can be improved.

Figure 6-Figure 7 As shown, the power driving board 60 is located on the upper side of the power assembly 10, the control board 70 is located on the upper side of the power driving board 60, and the shielding plate 80 separates the control board 70 from the power driving board 60. In other words, the power driving board 60, the shielding plate 80 and the control board 70 are arranged in sequence above the power assembly 10. The power driving board 60 and the control board 70 are separated by the shielding plate 80 to prevent the power driving board 60 from interfering with the signal on the control board 70 when the power driving board 60 is working.

[0096] In other embodiments, the power driving board 60 may be located on the side of the power component 10 facing the capacitor component 30, the control board 70 is located on the side of the power driving board 60 facing away from the power component 10, and a shielding plate 80 is provided between the control board 70 and the power driving board 60.

[0097] Optionally, the power component 10 is an IGBT component, and the power driving board 60 is an IGBT driving board.

[0098] In some embodiments of the present invention, the electric control assembly further includes a three-phase assembly 20, one end of which is fixedly connected to the power assembly 10, and the other end of which is connected to the motor body in the motor housing 4012; the three-phase assembly 20, the power assembly 10, the circuit board and the electric control cover 50 are connected to the first housing 40 as a whole. In this way, the assembly steps can be simplified and the assembly efficiency can be improved.

[0099] The motor body is connected to the motor shaft, and the power of the motor body is output through the motor shaft. In other words, the motor shaft is the power output shaft of the motor body.

In other words, the three-phase adapter cable 25 plays a role in connecting the power three-phase output terminal 11 and the motor three-phase line, and the three-phase assembly 20 is used to connect the power assembly 10 to the motor end.

[0101] The three-phase assembly 20 is installed on the electric control cover 50, the three-phase transfer cable 25 is connected to the three-phase line of the motor through the cover through hole 506 and the shell end opening 404, and the power assembly 10 is connected to the capacitor assembly 30 through the cover through hole 506 and the shell end opening 404. The cover through hole 506 and the shell end opening 404 facilitate the connection between the electric control end and the motor end.

[0102] In some embodiments of the present invention, reference Figure 3 , Figure 8 As shown, the cover plate vias 506 include three-phase component vias 504 and connection vias 505, and the three-phase component vias 504 and connection vias 505 are independent holes. The three-phase adapter cable 25 is connected to the three-phase line of the motor through the three-phase component vias 504 and the shell end opening 404, and the power component 10 is connected to the capacitor component 30 through the connection vias 505 and the shell end opening 404. In this way, the cover plate vias 506 are designed as a plurality of small holes, and the cover plate vias 506 do not need to be designed to be large, so that the removed structure of the electric control cover plate 50 is less, the strength loss of the electric control cover plate 50 is less, and the modules in the electric control cavity of the electric control cover plate 50 can be better protected, and the probability of the modules in the electric control cavity of the electric control cover plate 50 falling into the first shell 40 can be reduced.

[0103] In some embodiments of the present invention, reference Figure 6-Figure 7 As shown, the three-phase assembly 20 also includes a current detection component 24, and the three-phase adapter cable 25 is also connected in series with the current detection component 24. The three-phase adapter cable 25 passes through the current detection component 24 to flow the three-phase current to the motor end. The current detection component 24 is used to detect the current on the three-phase adapter cable 25, so as to achieve the purpose of detecting the current between the capacitor assembly 30 and the motor end.

[0104] Optionally, the current detection element 24 may be a Hall sensor.

[0105] Reference Figure 6-Figure 7 As shown, the three-phase assembly 20 also includes a three-phase magnetic ring cavity 21, a three-phase magnetic ring 22, and a three-phase copper bar fixing seat 23. The three-phase magnetic ring 22 is installed in the three-phase magnetic ring cavity 21, and the three-phase transfer cable 25 is installed on the three-phase copper bar fixing seat 23. The three-phase assembly 20 is used to transfer the three-phase current at the capacitor assembly 30 and the power assembly 10 to the motor end.

[0106] The electric control cover plate 50, the power driving plate 60, the control plate 70, the shielding plate 80 and the three-phase assembly 20 together form at least a part of the integrated controller. Figure 1-Figure 3 The appearance and layout of the electric assembly 100 can be seen more intuitively, and the placement of the capacitor assembly 30 and the orientation of the integrated controller are also clear, that is, the integrated controller is located on the top of the first shell 40. The integrated controller can occupy a part of the space inside the first shell 40, or it can be completely located outside the first shell 40. The capacitor assembly 30 is installed inside the first shell 40. This layout method effectively utilizes the internal space of the first shell 40 and improves the integration of the electric assembly 100.

[0107] In some embodiments of the present invention, the motor housing 4012 and the electric control housing 4013 are an integrated piece. Therefore, the number of parts of the electric assembly 100 is small, which is conducive to saving assembly time and improving assembly efficiency.

[0108] In other embodiments of the present invention, the motor housing 4012 and the electric control housing 4013 are connected and fixed. Optionally, the motor housing 4012 and the electric control housing 4013 can be connected and fixed in a detachable manner by using threaded fasteners (such as bolts, screws, etc.), or can be connected and fixed in an irremovable manner by using rivets, bonding, welding, etc.

[0109] Similarly, in some embodiments of the present invention, the transmission housing 90 and the first housing 40 are integrated. Therefore, the number of parts of the electric assembly 100 is small, which is conducive to saving assembly man-hours and improving assembly efficiency.

[0110] In other embodiments of the present invention, the transmission housing 90 is connected and fixed to the first housing 40. Optionally, the transmission housing 90 and the first housing 40 can be connected and fixed in a detachable manner by threaded fasteners (such as bolts, screws, etc.), or can be connected and fixed in an irremovable manner by rivets, bonding, welding, etc.

[0111] The electric assembly 100 also includes a transmission body, which is arranged in the transmission housing 90, and the motor shaft is connected to the transmission body in a transmission manner; the transmission shaft 91 is connected to the transmission body in a transmission manner, and the transmission body can be a transmission assembly, such as a gear transmission assembly, and the transmission body is used to output the speed of the motor shaft from the transmission shaft 91 after speed change, and the transmission shaft 91 is rotatably mounted in the transmission shaft hole 406, and the transmission shaft 91 is located between the electric control cover plate 50 and the motor shaft. Since the capacitor installation area is located on one side of the transmission shaft hole 406, the capacitor assembly 30 is located on one side of the transmission shaft 91. In this way, the capacitor assembly 30 can make full use of the side space of the transmission shaft 91, does not interfere with the transmission shaft 91, and improves the space utilization rate inside the first housing 40.

[0112] In some embodiments of the present invention, the transmission shaft 91 is parallel to the motor shaft, which can simplify the manufacturing process of the transmission shaft hole 406 and the motor shaft hole 405. At the same time, the transmission shaft 91 and the motor shaft extend in the same direction, which is convenient for installing the transmission shaft 91 and the motor shaft.

[0113] The assembly process of the integrated controller of the electric assembly 100 according to the embodiment of the present invention can be: install the power component 10 on the cover body 503, install the three-phase component 20 on the cover body 503, connect the three-phase adapter cable 25 and the power three-phase output terminal 11 of the power component 10, install the power drive board 60 above the power component 10, install the shielding plate 80, install the control board 70 above the shielding plate 80, after installing various connectors, cover the small cover 502, tighten the bolts between the capacitor component 30 and the power component 10 through the opening 507 on the small cover 502, and then cover the protective cover 501. At this point, the assembly of the integrated controller is completed.

[0114] By placing the capacitor assembly 30 in the housing accommodating cavity 403 inside the electric control housing 4013, the electric control cover plate 50 is equipped with electric control components such as the power component 10, the shielding plate 80, the control board 70 and the three-phase component 20, and there is no need to reserve space for the capacitor assembly 30, which effectively reduces the weight and size of the electric control cover plate 50 and simplifies the structure of the electric assembly 100 to a certain extent. At the same time, the heat transfer between the electric control components on the electric control cover plate 50 and the capacitor assembly 30 is effectively reduced, which is beneficial to the heat dissipation of the capacitor assembly 30 and the heat dissipation of the electric control components on the electric control cover plate 50.

[0115] Reference Figure 1 and Figure 2 , open the housing cover 402, install the capacitor assembly 30 in the housing accommodating cavity 403 inside the electric control housing 4013, then install the integrated controller above the electric control housing 4013, and connect and fix the cover body 503 and the electric control housing 4013 with mounting screws. Open the protective cover 501 of the integrated controller, connect and fix the power positive input terminal 12 with the capacitor positive output terminal 31 through the opening 507, connect and fix the power negative input terminal 13 with the capacitor negative output terminal 32, and then cover the protective cover 501. Connect the three-phase adapter cable 25 with the three-phase line of the motor, so that the entire circuit connection is completed. At this point, the integrated controller and the motor end are assembled.

[0116] In some embodiments, reference Figure 2 As shown, the electric assembly 100 further includes a motor terminal block 15, which can be disposed on the electric control cover plate 50 or in the first housing 40, and the three-phase transfer cable 25 is indirectly connected to the three-phase line of the motor through the motor terminal block 15. Specifically, the motor terminal block 15 is provided with an electric control three-phase connection terminal 14 and a motor three-phase connection terminal 16, the electric control three-phase connection terminal 14 and the motor three-phase connection terminal 16 are conductive, the three-phase transfer cable 25 is connected to the electric control three-phase connection terminal 14, and the motor three-phase line is connected to the motor three-phase connection terminal 16, so that the current at the three-phase transfer cable 25 can be conducted to the motor three-phase line via the electric control three-phase connection terminal 14 and the motor three-phase connection terminal 16.

[0117] The electric assembly 100 according to the embodiment of the present invention removes the capacitor assembly 30 from the electric control cover plate 50 and places it outside the electric control cover plate 50 and in the first housing 40, which can better save space. According to the layout of the whole vehicle, considering the extremely small space left by the whole vehicle, through the streamlined layout of each module, the size of the electric control cover plate 50 can be reduced and the scattered space can be utilized, which is conducive to reducing the length of the internal wiring, thereby simplifying the structure of the electric assembly 100 and reducing the occupied space. In this way, the height of the electric assembly 100 is reduced, saving the space and weight of the entire product, making it lighter and saving costs.

By setting the absolute value of the difference between the dimensions of the electric control cover plate 50 and the transmission housing 90 protruding from the first housing 40 in the first direction to not more than 40 mm, the outer contour envelope dimension of the electric control cover plate 50 in the first direction is relatively small compared with the outer contour envelope dimension of the transmission housing 90 in the first direction, and the arrangement of the electric control cover plate 50 will not affect the envelope dimension of the electric assembly 100 in the first direction too much; by setting the projection of the electric control cover plate 50 and the electric control housing 4013 in a plane perpendicular to the first direction to be within the projection range of the motor housing 4012 in the plane, the arrangement of the electric control cover plate 50 and the electric control housing 4013 will not increase the envelope dimension of the electric assembly 100 in a plane perpendicular to the first direction; thus, the electric control cover plate 50 will not occupy too much extra space, and the special-shaped space of the electric assembly 100 is fully utilized, thereby achieving the effect of improving the space utilization rate of the electric assembly 100 and making the electric assembly 100 compact. Special-shaped space of the electric assembly 100.
