[0036] The embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0037] The following describes an embodiment of the motor pump of this utility model.
[0038] See Figures 1 to 6 The motor pump 100 of this utility model embodiment includes a housing 1, a first motor 21, a second motor 22, a controller 3, and a cover plate 35.
[0039] A partition 15 is provided in the inner cavity of the housing 1 to divide the inner cavity of the housing 1 into a first motor cavity 11, a second motor cavity 12, and an electrical control cavity. The first motor cavity 11 and the second motor cavity 12 are staggered in a first direction. It is understood that the housing 1 includes an outer peripheral plate located on its circumferential periphery, which defines the inner cavity of the housing 1. The partition 15 is located in the middle of the outer peripheral plate, dividing the inner cavity of the housing 1 into the relatively independent first motor cavity 11, second motor cavity 12, and electrical control cavity. The first motor cavity 11, second motor cavity 12, and electrical control cavity all have openings. The first direction is the left-right direction shown in the figure. The first motor cavity 11 is located on the left side of the inner cavity of the housing 1, and the second motor cavity 12 is located on the right side of the inner cavity of the housing 1. The first motor cavity 11 and the second motor cavity 12 are staggered in the left-right direction.
[0040] The electrical control cavity is located on the side of the first motor cavity 11 and the second motor cavity 12. For example, when the inner cavity of the housing 1 is generally rectangular, the remaining cavity on the right side of the first motor cavity 11 and the remaining cavity on the left side of the second motor cavity 12 are defined as the electrical control cavity.
[0041] The first motor 21 is disposed in the first motor cavity, and the second motor 22 is disposed in the second motor cavity.
[0042] The controller 3 has a PCB board 31 and electrical components 32 arranged on the PCB board 31. The PCB board 31 is disposed in the electrical control cavity. The PCB board 31 can be placed inside the electrical control cavity or placed at the opening of the electrical control cavity. The electrical components 32 are accommodated inside the electrical control cavity, so that the side of the PCB board 31 facing away from the electrical control cavity can be relatively flat.
[0043] The cover plate 35 is located at the opening of the electrical control cavity, and is connected to the housing 1 so that the PCB board 31 is placed inside the cover plate 35. In this case, the cover plate 35 has a simple structure. As a cover plate sealing the PCB board 31 and the electrical components 32, the controller 3 is placed in a stable sealed space, without needing to reserve excessive space for the installation of the electrical components 32. Compared to the controller housing in related technologies, the cover plate 35 in this embodiment is lower and has a simpler structure.
[0044] In this embodiment, the motor and controller 3 share the same housing 1. The internal space of the housing 1 is reasonably distributed and separated from each other by partitions 15, so they do not affect each other. It has strong anti-interference ability, facilitates the arrangement of the motor and controller 3, and has a simple and reliable sealing and assembly structure with high assembly efficiency.
[0045] The following describes the motor pump 100 in some specific embodiments of the present invention.
[0046] See Figures 1 to 6The electric motor pump 100 of this utility model embodiment includes a housing 1, a first motor 21, a second motor 22, a controller 3, a cover plate 35, a first pump 41, and a second pump 42.
[0047] The inner cavity of the housing 1 has a partition 15 to divide the inner cavity of the housing 1 into a first motor cavity 11, a second motor cavity 12, a first electrical control cavity 13, and a second electrical control cavity 14. The first motor cavity 11 and the second motor cavity 12 are staggered in a first direction. It is understood that the housing 1 includes an outer peripheral plate located on its circumferential periphery, defining the inner cavity of the housing 1. The partition 15 is disposed in the middle of the outer peripheral plate, dividing the inner cavity of the housing 1 into the relatively independent first motor cavity 11, second motor cavity 12, and electrical control cavity. The first motor cavity 11, second motor cavity 12, and electrical control cavity all have openings. The first direction is the left-right direction shown in the figure. The first motor cavity 11 is located on the left side of the inner cavity of the housing 1, and the second motor cavity 12 is located on the right side of the inner cavity of the housing 1. The first motor cavity 11 and the second motor cavity 12 are staggered in the left-right direction.
[0048] The first electronic control cavity 13 and the second electronic control cavity 14 are located on the sides of the first motor cavity 11 and the second motor cavity 12. In this embodiment, the inner cavity of the housing 1 is generally rectangular, the remaining cavity on the right side of the first motor cavity 11 is defined as the first electronic control cavity 13, and the remaining cavity on the left side of the second motor cavity 12 is defined as the second electronic control cavity 14.
[0049] It is understood that the first motor cavity 11, the second motor cavity 12, the first electronic control cavity 13, and the second electronic control cavity 14 are arranged circumferentially along the inner cavity of the housing 1. The first motor cavity 11 and the second motor cavity 12 are arranged diagonally in the inner cavity of the housing 1, and the first electronic control cavity 13 and the second electronic control cavity 14 are arranged diagonally in the inner cavity of the housing 1.
[0050] In this embodiment, the opening direction of the first motor cavity 11 is parallel to the first direction and away from the second motor cavity 12 (the opening direction of the first motor cavity 11 is...). Figure 1 (Left side of the first motor cavity 11), the opening direction of the second motor cavity 12 is parallel to the first direction and away from the first motor cavity 11 (the opening direction of the second motor cavity 12 is towards the first motor cavity 11). Figure 1 (on the right side of the image), the opening directions of the first electronically controlled cavity 13 and the second electronically controlled cavity 14 are the same and orthogonal to the first direction (the opening directions of the first electronically controlled cavity 13 and the second electronically controlled cavity 14 are facing...). Figure 1 (The upper side of the middle).
[0051] A first motor 21 is disposed within a first motor cavity, and a first pump 41 is connected to a housing 1 at the opening of the first motor cavity 11, and the first pump 41 is drive-connected to the first motor 21. A second motor 22 is disposed within a second motor cavity, and a second pump 42 is connected to a housing 1 at the opening of the second motor cavity 12, and the second pump 42 is drive-connected to the second motor 22.
[0052] The controller 3 has a PCB board 31, electrical components 32 arranged on the PCB board 31, a high-voltage connector 33, and a low-voltage connector 34. The PCB board 31 includes a drive board 311 and a control board 312. The drive board is disposed at the opening of a first electrical control cavity 13, and the electrical components 32 on the drive board are housed within the first electrical control cavity 13. The control board is disposed at the opening of a second electrical control cavity 14, and the electrical components 32 on the control board are housed within the second electrical control cavity 14. The main electrical components 32 on the drive board and the control board are arranged within their respective electrical control cavities, so that the side facing away from the electrical control cavity is relatively flat, avoiding the placement of large electrical components 32 on the side of the drive board and the control board facing away from the electrical control cavity.
[0053] The drive board 311 and the control board 312 can be installed separately. That is, some electrical components are arranged on the drive board 311 and some electrical components are arranged on the control board 312, thus forming two separate and relatively independent PCBA boards. During installation, the drive board 311 and the control board 312 are installed in the first electrical control cavity 13 and the second electrical control cavity 14, respectively.
[0054] The drive board 311 and the control board 312 can also be integrated. It can be understood that the drive board 311 and the control board 312 are two different areas of the same PCB board. The electrical components on the drive board 311 can be accommodated in the first electrical control cavity 13, and the electrical components on the control board 312 can be accommodated in the second electrical control cavity 14.
[0055] In this embodiment, the drive board and control board can be arranged on the same plane, whether they are separate or integrated. The electrical components 32 on the drive board and control board are respectively located in the first electrical control cavity 13 and the second electrical control cavity 14, and can be physically isolated by the partition 15.
[0056] Compared to related technologies where the controller's drive board and control board are stacked and require a shielding layer for isolation, the controller 3 in this embodiment has a simpler assembly structure, stronger anti-interference capability, and can share the same housing 1 with the motor. The control board and drive board are arranged on the same plane. The overall structure has high stability, simplifies the structure of the controller 3, and eliminates the need for a separate housing 1; only a cover plate 35 is needed for sealing the controller 3.
[0057] The cover plate 35 is located at the opening of the electrical control cavity. The cover plate 35 is connected to the housing 1 so that the drive plate and control plate are placed inside the cover plate 35. At this time, the cover plate 35 has a simple structure. As a cover plate that seals the drive plate, control plate, and electrical components 32, the controller 3 is placed in a stable sealed space. In this embodiment, the cover plate 35 does not need to reserve too much space for the installation of electrical components 32. The cover plate 35 has a low thickness and a simpler structure.
[0058] Both the high-voltage connector 33 and the low-voltage connector 34 are connected to the housing 1. Mounting holes are provided on the housing 1, and the high-voltage connector 33 and the low-voltage connector 34 are fixed to the housing 1 by connectors. Specifically, mounting portions corresponding to the high-voltage connector 33 and the low-voltage connector 34 are provided on the outer side of the housing 1 opposite to the openings of the first and second electrical control cavities 13 and 14, and the high-voltage connector 33 and the low-voltage connector 34 are connected to the corresponding mounting portions.
[0059] Compared to related technologies that connect high-voltage and low-voltage connectors to the controller housing, the cover plate 35 in this embodiment has a simpler structure, a flatter shape, and a smaller size, making it easier to manufacture and assemble. This embodiment makes full use of the structure and space of the housing 1, resulting in a more reasonable assembly position between the high-voltage connector 33 and the low-voltage connector 34 and the PCB board 31 and electrical components 32, and better stability.
[0060] In this embodiment, at least a portion of the partition 15 is provided with through holes 16 to connect two adjacent cavities. For example, through holes 16 are provided on the partition 15 at the tail end (the end opposite to the motor output shaft) of the first motor cavity 11 and the second motor cavity 12 to facilitate the assembly of the first motor 21 and the second motor 22. As another example, through holes 16 are provided on the partition 15 for cable connection between the first motor 21, the second motor 22 and the controller 3.
[0061] In this embodiment, the motor and controller share the same housing. By dividing the internal space of the housing and arranging the openings of each cavity, the assembly of the motor and controller is facilitated. The internal space distribution of the housing is reasonable, and the components are separated by partitions, ensuring they do not interfere with each other and providing strong anti-interference capabilities. In particular, the drive board and control board in the controller are physically isolated, improving the stability of the electrical control and preventing interference between high- and low-voltage components. The sealing structure of the cover plate and housing is simple, employing a ring-shaped sealing housing, which solves the problems of complex assembly processes and poor sealing effects associated with T-type sealing structures in related technologies. Furthermore, the assembly structure between components in this embodiment is simple and reliable, easy to position, does not interfere with each other, and has high assembly efficiency.
