Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and more specifically, to an electric pump and a vehicle. Background Technology

[0002] Electric motor pumps can be used in vehicle active suspension systems. By adjusting the shock absorber height through pressure output, they can achieve highly dynamic adjustment of the suspension system for each wheel, ensuring the vehicle remains stable on uneven roads and thus improving driving comfort. The housing of an electric motor pump typically includes a motor housing and an electronic control housing, which house the motor and controller, respectively.

[0003] In related technologies, the chamber of the motor housing is usually connected to the chamber of the electrical control housing to achieve electrical connection between the motor and the controller. The mating surfaces of the housings are typically sealed using sealant, sealing rings, or gaskets. Existing motor pumps suffer from poor sealing at the housing mating points. Utility Model Content

However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0041] Unless otherwise specified or stated, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “a,” “an,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “comprising” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to those listed; the terms “first” and “second” are used only as illustrative marks and are not intended to limit the number, importance, or order of the objects.

[0042] The terms “connection” and “fixation” should be interpreted broadly. For example, “connection” can be a fixed connection, a movable connection, an integral connection, or a detachable connection. It can be a direct connection or an indirect connection through an intermediate medium.

[0043] In the description of this disclosure, it should be understood that the terms "inner / outer", "height", "longitudinal / lateral", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this disclosure and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure.

[0044] In this disclosure, the term "separated" is used to indicate that there is no overlap between two structures. For example, if structure A is separated from structure B, it means that structure A and structure B are not in direct contact and there are no overlapping / shared edges.

[0045] This disclosure provides an electric motor pump, with reference to... Figures 1 to 5 As shown, it includes a motor housing and an electronic control housing. The motor housing includes a first motor housing 1 and a second motor housing 2. The first motor housing 1 has a first opening 11, and the second motor housing 2 has a second opening 21. The electronic control housing has a third opening 31 and a fourth opening 32. The first opening 11 and the second opening 21 are separate, the third opening 31 and the fourth opening 32 are separate, the first opening 11 and the third opening 31 are connected, and the second opening 21 and the fourth opening 32 are connected.

[0046] The electric motor pump disclosed herein, when the motor housing and the electrical control housing are connected, has a first opening 11 and a third opening 31 connected, allowing the controller inside the electrical control housing to be electrically connected to the first motor inside the first motor housing 1 through the first opening 11 and the third opening 31; similarly, a second opening 21 and a fourth opening 32 connected, allowing the controller inside the electrical control housing to be electrically connected to the second motor inside the second motor housing 2 through the second opening 21 and the fourth opening 32. The electrical connections between the controller and the two motors are independent, and the wiring does not affect each other, which increases the difficulty of assembling the electric motor pump and reduces the failure rate of the wiring harness. Because the first opening 11 is separate from the second opening 21, and the third opening 31 is separate from the fourth opening 32, the two mating parts of the electrical control housing and the motor housing can be isolated, thereby simplifying the joint structure at the mating point of the electrical control housing and the motor housing, reducing the sealing difficulty, and making it easier to achieve a sufficient seal. This improves the sealing performance of the electric motor pump and reduces costs.

[0047] In exemplary embodiments of this disclosure, the sealing measures between the first opening 11 and the third opening 31, and between the second opening 21 and the fourth opening 32, can be independent of each other and can be the same or different. For example, refer to... Figures 2 to 4As shown, the first motor housing 1 has a first mounting surface, and a first opening 11 is provided on the first mounting surface; the electrical control housing has a fifth mounting surface for mating with the first mounting surface, and a third opening 31 is provided on the fifth mounting surface. A first sealing element 51 is provided between the first mounting surface and the fifth mounting surface. The second motor housing 2 has a second mounting surface, and a second opening 21 is provided on the second mounting surface; the electrical control housing has a sixth mounting surface for mating with the second mounting surface, and a fourth opening 32 is provided on the sixth mounting surface. A second sealing element 52 is provided between the second mounting surface and the sixth mounting surface. Because the motor pump provided in this disclosure simplifies the joint structure at the interface between the electrical control housing and the motor housing, it simplifies the use of sealing elements, reduces costs, and achieves better sealing performance.

[0048] The first mounting surface and the fifth mounting surface, and / or the second mounting surface and the sixth mounting surface, can also be sealed with a sealant. Because the motor pump provided in this disclosure simplifies the joint structure, the application of sealant is easier, and it is less likely to cause sealant overflow or leakage problems. The sealant may include modified composite rubber, polyurethane, silane-modified resin, etc., and the sealing components may include gaskets such as rubber gaskets, asbestos gaskets, metal gaskets, etc., and sealing rings such as rubber sealing rings. For example, the first sealing component 51 and the second sealing component 52 may be O-rings.

[0049] It should be noted that, in the exemplary embodiments of this disclosure, for ease of description, the axial direction of the motor pump, i.e., the axial direction of the motor, is taken as the first direction X, and two orthogonal directions in a plane perpendicular to the first direction are taken as the second direction Z and the third direction Y, respectively. Wherein, reference... Figure 1 As shown, the direction between the electronic control housing and the motor housing is... Figure 1 The height direction is taken as the second direction.

[0050] Referring to the attached figures, the first mounting surface, the fifth mounting surface, the second mounting surface, and the sixth mounting surface are all perpendicular to the second direction Z direction, that is, the first mounting surface, the fifth mounting surface, the second mounting surface, and the sixth mounting surface are all parallel to the XY plane.

[0051] In one exemplary embodiment of this disclosure, reference is made to Figure 3 , Figure 4As shown, the projections of the first mounting surface and the fifth mounting surface along the second direction Z coincide, and the projections of the second mounting surface and the sixth mounting surface along the second direction Z coincide. That is, the area and shape of the first mounting surface and the fifth mounting surface are consistent; the area and shape of the second mounting surface and the sixth mounting surface are consistent. After the first motor housing 1, the second motor housing 2, and the electrical control housing are assembled, the first mounting surface coincides with the fifth mounting surface, and the second mounting surface coincides with the sixth mounting surface, in order to improve the stability of the connection between the first motor housing 1, the second motor housing 2, and the electrical control housing, and to improve the sealing effect at the mounting surfaces.

[0052] In one exemplary embodiment of this disclosure, reference is made to Figures 1 to 5 As shown, the first motor housing 1 and the second motor housing 2 are separate structures. The first motor housing 1 has a third mounting surface, and the second motor housing 2 has a fourth mounting surface; both the third and fourth mounting surfaces are perpendicular to the X-axis of the motor. The first motor housing 1 and the second motor housing 2 are joined together through the third and fourth mounting surfaces to form the motor housing. This embodiment allows for independent installation of the first and second motors, which improves installation efficiency and accuracy, reduces the processing difficulty of the motor housing, and results in better alignment and performance of the assembled motor pump.

[0053] Specifically, the first motor housing 1 has a first mounting cavity for mounting the first motor; the second motor housing 2 has a second mounting cavity for mounting the second motor; and the electronic control housing has a third mounting cavity for mounting the controller. The first mounting cavity can communicate with the third mounting cavity of the electronic control housing through the first opening 11 and the third opening 31 for wiring between the first motor and the controller. The second mounting cavity can communicate with the third mounting cavity of the electronic control housing through the second opening 21 and the fourth opening 32 for wiring between the second electrode and the controller. For example, the first opening 11 and the third opening 31 have the same shape and size, both being oblong holes with a length along the Y direction; the second opening 21 and the fourth opening 32 also have the same shape and size, and can also be oblong holes with a length along the Y direction. The shapes and sizes of the first opening 11, the third opening 31, the second opening 21, and the fourth opening 32 can all be the same.

[0054] For example, the third mounting surface is separated from the first opening 11, and the fourth mounting surface is separated from the second opening 21. The mating parts of the first motor housing 1 and the second motor housing 2 can be isolated from the mating parts of the electrical control housing and the motor housing. This simplifies the joint structure at the joints of the various housings of the motor pump, ensuring that the three joints between the motor housing and the electrical control housing do not intersect, reducing the difficulty of sealing, simplifying the structure of the sealing element, and improving the sealing effect, making leakage less likely.

[0055] For example, refer to Figure 2 , Figure 5 As shown, the first motor housing 1 and the second motor housing 2 are interconnected. The first motor housing 1 has a fifth opening 12 on the third mounting surface, and the second motor housing 2 has a sixth opening 22 on the fourth mounting surface. The fifth opening 12 and the sixth opening 22 are interconnected. Connectors and other components can be installed at the connection point between the first motor housing 1 and the second motor housing 2. Furthermore, the fifth opening 12 and the sixth opening 22 can reduce the difficulty of installing the motor into the motor housing, improving installation efficiency and accuracy. For example, both the fifth opening 12 and the sixth opening 22 are located along the X direction.

[0056] The sealing connection between the third mounting surface and the fourth mounting surface can be achieved, for example, by using a sealant, which may include modified composite rubber, polyurethane, silane-modified resin, etc. In some exemplary embodiments of this disclosure, a third sealing element 53 may be provided between the third mounting surface and the fourth mounting surface. For example, one or both of the third and fourth mounting surfaces may have a third sealing groove. The third sealing element 53 can be a sealing ring, and at least a portion of the third sealing element 53 is installed within the third sealing groove. When the first motor housing 1 and the second motor housing 2 are mated, the third and fourth mounting surfaces compress the third sealing element 53. The tendency of the third sealing element 53 to return to its original shape after compression can improve the sealing performance between the first motor housing 1 and the second motor housing 2. The third sealing element 53 is also separated from the first opening 11 and the second opening 21.

[0057] In this exemplary embodiment, the seals between the first opening 11 and the third opening 31, the second opening 21 and the fourth opening 32, and the fifth opening 12 and the sixth opening 22 are all isolated. When sealing, the same or different sealing methods and structures can be used, which is beneficial for achieving a better sealing effect. For example, the housings of the motor pump can be sealed with sealant. Since the sealing positions do not intersect, the application of sealant is easy, and there is no seal at the junction of the three housings, thus reducing the likelihood of sealant overflow or leakage. Alternatively, the housings of the motor pump can be sealed with a sealing element. Since this exemplary embodiment simplifies the joint structure at the connection between the housings of the motor pump, it is not necessary to use irregularly shaped sealing elements with intersecting planes, thereby simplifying the sealing elements used, reducing costs, and achieving a better sealing effect.

[0058] In one exemplary embodiment of this disclosure, reference is made to Figure 3As shown, the outer periphery of the third opening 31 is provided with a first pressing portion 33 protruding from the surface of the electronic control housing, and the outer periphery of the fourth opening 32 is provided with a second pressing portion 34 protruding from the surface of the electronic control housing. The first pressing portion 33 can be used to press the first sealing member 51; the second pressing portion 34 can be used to press the second sealing member 52. The surface of the first pressing portion 33 away from the electronic control housing can form the aforementioned fifth mounting surface, and the surface of the second pressing portion 34 away from the electronic control housing can form the aforementioned sixth mounting surface.

[0059] A sealing connection is formed between the first mounting surface and the fifth mounting surface. For example, a first sealing groove is provided around the outer periphery of the first opening 11 on the first mounting surface. At least a portion of the first sealing element 51 is installed in the first sealing groove. The first pressing part 33 on the fifth mounting surface presses the first sealing element 51 tightly into the first sealing groove, which can compress the first sealing element 51. The first sealing element 51 can be a sealing ring, sealing gasket, etc. The tendency of the first sealing element 51 to return to its original shape after compression can improve the sealing performance between the electronic control housing and the first motor housing 1. A sealing connection is formed between the second mounting surface and the sixth mounting surface. For example, a second sealing groove can be provided around the outer periphery of the second opening 21 on the second mounting surface. At least a portion of the second sealing element 52 is installed in the second sealing groove. The second pressing part 34 on the sixth mounting surface presses the second sealing element 52 tightly into the second sealing groove, which can compress the second sealing element 52. The second sealing element 52 can be a sealing ring, sealing gasket, etc. The tendency of the second sealing element 52 to return to its original shape after compression can improve the sealing performance between the electronic control housing and the second motor housing 2.

[0060] For example, a first sealing groove is provided around the outer periphery of the third opening 31 on the fifth mounting surface. At least a portion of the first sealing member 51 is installed in the first sealing groove. The first mounting surface presses the first sealing member 51 tightly into the first sealing groove, which can improve the sealing performance between the electronic control housing and the first motor housing 1. A second sealing groove is provided around the outer periphery of the fourth opening 32 on the sixth mounting surface. At least a portion of the second sealing member 52 is installed in the second sealing groove. The second mounting surface presses the second sealing member 52 tightly into the second sealing groove, which can improve the sealing performance between the electronic control housing and the second motor housing 2.

[0061] For example, refer to Figure 2 As shown, the first motor housing 1 has a first support base 13 protruding from the first motor housing 1 along the Z direction, and a first opening 11 extending through the first support base 13 along the Z direction. The second motor housing 2 has a second support base 23 protruding from the second motor housing 2 along the Z direction, and a second opening 21 extending through the second support base 23 along the Z direction. Exemplarily, the first support base 13 and the second support base 23 are separate.

[0062] In this exemplary embodiment, the first support base 13 and the second support base 23 can further isolate the mating surfaces of the first motor housing 1 and the second motor housing 2 and the mating surface of the electrical control housing and the motor housing, thereby simplifying the joint structure at the mating points of each housing.

[0063] Exemplarily, the end of the first support base 13 away from the first motor housing 1, i.e., the top surface of the first support base 13, forms a first mounting surface for supporting the fifth mounting surface of the electronic control housing; the end of the second support base 23 away from the second motor housing 2, i.e., the top surface of the second support base 23, forms a second mounting surface for supporting the sixth mounting surface of the electronic control housing. Exemplarily, the first mounting surface and the second mounting surface are coplanar. This exemplary embodiment can limit the sealing area between the electronic control housing and the motor housing to between the first mounting surface and the electronic control housing, and between the second mounting surface and the electronic control housing, thereby reducing the area of ​​the surfaces to be sealed and reducing the processing difficulty.

[0064] For example, the first support base 13 and the first crimping part 33 are connected to the fifth mounting surface through the first mounting surface; the second support base 23 and the second crimping part 34 are connected to the sixth mounting surface through the second mounting surface.

[0065] In one exemplary embodiment of this disclosure, the first crimping portion 33 and the second crimping portion 34 are separated. (See reference...) Figure 3 As shown, the first crimping part 33 and the second crimping part 34 are separated, which can further isolate the seal of the first opening 11 and the seal of the second opening 21, so that the seal of the first opening 11 and the seal of the second opening 21 do not affect each other. On the one hand, it is conducive to a full seal, and on the other hand, it is also conducive to independently inspecting, adjusting and other operations on the seal of the first opening 11 and the seal of the second opening 21.

[0066] In one exemplary embodiment of this disclosure, reference is made to Figure 4As shown, the dimension of the first support base 13 in the third direction (Y) is smaller than the maximum dimension of the first motor housing 1 in the Y direction. Specifically, in one embodiment, the dimension of the first support base 13 in the Y direction is smaller than the outer diameter of the first mounting cavity region of the first motor housing 1. The orthographic projection of the first support base 13 onto the first motor housing 1 in the second direction (Z) falls within the range of the first motor housing 1, resulting in higher structural strength of the first support base 13 and making it less susceptible to impacts, which is beneficial for improving the sealing performance of the first opening 11 and the third opening 31. For example, the dimension of the second support base 23 in the Y direction is smaller than the maximum dimension of the second motor housing 2 in the Y direction. Specifically, in one embodiment, the dimension of the second support base 23 in the Y direction is smaller than the outer diameter of the second mounting cavity region of the second motor housing 2. The orthographic projection of the second support base 23 onto the second motor housing 2 in the Z direction falls within the range of the second motor housing 2, resulting in higher structural strength of the second support base 23 and making it less susceptible to impacts, which is beneficial for improving the sealing performance of the second opening 21 and the fourth opening 32.

[0067] In one exemplary embodiment of this disclosure, the first support 13 and the second support 23 are symmetrical with respect to the third mounting surface and the fourth mounting surface, respectively. For example, the distance of the first support 13 from the third mounting surface in the first direction is equal to the distance of the second support 23 from the fourth mounting surface in the first direction. The height of the first support 13 in the second direction is equal to the height of the second support 23 in the second direction.

[0068] In some exemplary embodiments, reference Figure 3 As shown, the dimension of the first crimping portion 33 in the Y direction is smaller than the maximum dimension of the electronic control housing in the Y direction, and the dimension of the second crimping portion 34 in the Y direction is also smaller than the maximum dimension of the electronic control housing in the Y direction. The orthographic projection of the first crimping portion 33 onto the bottom surface of the electronic control housing in the Z direction falls within the area of ​​the bottom surface of the electronic control housing, making the first crimping portion 33 less susceptible to impacts and improving the sealing performance of the first opening 11 and the third opening 31. Similarly, the projection of the second crimping portion 34 onto the bottom surface of the electronic control housing in the Z direction falls within the area of ​​the bottom surface of the electronic control housing, making the second crimping portion 34 less susceptible to impacts and improving the sealing performance of the second opening 21 and the fourth opening 32.

[0069] In one exemplary embodiment of this disclosure, reference is made to Figure 1 , Figure 2 , Figure 4 as well as Figure 5As shown, the first motor housing 1 has a third support 14 protruding from the first motor housing 1 in a second direction, and the third support 14 is connected to the bottom surface of the electrical control housing, which has a third opening 31 and a fourth opening 32. The second motor housing 2 has a fourth support 24 protruding from the second motor housing 2 in a second direction, and the fourth support 24 is connected to the bottom surface of the electrical control housing, which has a third opening 31 and a fourth opening 32. Specifically, the electrical control housing and the first motor housing 1 can be connected by a threaded connector. (Reference) Figure 1 As shown, after passing through the electrical control housing, the bolt is screwed into the threaded hole on the third support 14 to fix the electrical control housing to the first motor housing 1. Similarly, after passing through the electrical control housing, the bolt is screwed into the threaded hole on the fourth support 24 to fix the electrical control housing to the second motor housing 2.

[0070] For example, the contact surface between the third support 14 and the electrical control housing is parallel to the first mounting surface and the fifth mounting surface. The contact surface between the fourth support 24 and the electrical control housing is parallel to the second mounting surface and the sixth mounting surface.

[0071] For example, refer to Figure 1 , Figure 2 as well as Figure 4 As shown, the third support base 14 includes support columns 141 located at opposite ends in a third direction, and a bridging portion 142 located between the two support columns 141. The height of the support columns 141 in a second direction is greater than that of the bridging portion 142. The support columns 141 are connected to the electrical control housing, while the bridging portion 142 is separate from the electrical control housing. For example, after the bolt passes through the two through holes on opposite sides in a third direction of the electrical control housing, it is screwed into the threaded holes on the two support columns 141 of the third support base 14 to fix the electrical control housing to the first motor housing 1.

[0072] The bridging portion 142 can enhance the strength and rigidity of the third support base 14, ensuring the stability of the connection between the electrical control housing and the first motor housing 1. Exemplarily, the electrical control housing and the first motor housing 1 are separated except for contact between the first support base 13 and the third support base 14. Specifically, the electrical control housing and the first motor housing 1 are separated except for contact between the first pressing portion 33 and the top surface of the first support base 13, and contact between the bottom surface of the electrical control housing and the third support base 14. In this exemplary embodiment, the electrical control housing and the first motor housing 1 only contact the top surface of the first support base 13 through the first pressing portion 33, achieving a seal between the first opening 11 and the third opening 31; the connection between the electrical control housing and the first motor housing 1 is achieved only through the bottom surface of the electrical control housing and the third support base 14. This helps reduce the requirements for machining accuracy and assembly accuracy, and provides sufficient pressure for the first sealing element 51.

[0073] For example, refer to Figure 1 , Figure 2 as well as Figure 4 As shown, the fourth support 24 can have the same structure as the third support 14, for example, including second support columns located at opposite ends in a third direction and a second bridging portion located between the two second support columns. The height of the second support columns in the second direction is greater than that of the second bridging portion. The second support columns are connected to the electrical control housing, while the second bridging portion is separate from the electrical control housing. For example, after the bolt passes through two through holes on the electrical control housing corresponding to the fourth support 24, it is screwed into the threaded holes on the two second support columns of the fourth support 24 to fix the electrical control housing to the second motor housing 2.

[0074] The second bridging portion enhances the strength and rigidity of the fourth support base 24, ensuring the stability of the connection between the electrical control housing and the second motor housing 2. Exemplarily, the electrical control housing and the second motor housing 2 are separated except for contact between the second support base 23 and the fourth support base 24. Specifically, the electrical control housing and the second motor housing 2 are separated except for contact between the second pressing portion 34 and the top surface of the second support base 23, and between the bottom surface of the electrical control housing and the fourth support base 24. In this exemplary embodiment, the electrical control housing and the second motor housing 2 only contact the top surface of the second support base 23 through the second pressing portion 34, achieving a seal between the second opening 21 and the fourth opening 32; the connection between the electrical control housing and the second motor housing 2 is achieved only through the bottom surface of the electrical control housing and the fourth support base 24. This helps reduce the requirements for machining accuracy and assembly accuracy, and provides sufficient pressure for the second sealing element 52.

[0075] In some exemplary embodiments of this disclosure, the first motor housing 1 may be provided with more than one third support base 14 along the first direction, and correspondingly, the electrical control housing may be provided with more than one set of connection holes that match the third support base 14. The second motor housing 2 may be provided with more than one fourth support base 24 along the first direction, and correspondingly, the electrical control housing may be provided with more than one set of connection holes that match the fourth support base 24.

[0076] In one exemplary embodiment of this disclosure, reference is made to Figures 1 to 3 As shown, the side of the electrical control housing is provided with a receiving cavity 35, which can be used to accommodate the connecting parts that connect the electrical control housing and the motor housing. For example, the electrical control housing and the motor housing are connected by connecting bolts. The electrical control housing has multiple connecting holes on both sides in the Y direction for connecting with the motor housing. The connecting holes can correspond one-to-one with the support column 141 of the third support base 14 and the second support column of the fourth support base 24. When connecting the electrical control housing and the motor housing with connecting bolts, the connecting bolts can pass from top to bottom through the connecting holes on the electrical control housing from the receiving cavity 35 and be screwed into the support column 141 of the third support base 14 and the second support column of the fourth support base 24.

[0077] In one exemplary embodiment of this disclosure, reference is made to Figure 1 and Figure 2 As shown, the electronic control housing includes a first electronic control housing 3 and a second electronic control housing 4. The second electronic control housing 4 is mounted on the side of the first electronic control housing 3 away from the fifth opening. The first electronic control housing 3 and the second electronic control housing 4 together form a third mounting cavity. In this exemplary embodiment, reference is made to... Figure 1 and Figure 2 As shown, the split-type electrical control housing facilitates the connection between the first electrical control housing 3 and the first motor housing 1 and the second motor housing 2. When assembling the motor pump of this disclosure, after the first motor housing 1 and the second motor housing 2 are connected, the first electrical control housing 3 can be installed on top of the first motor housing 1 and the second motor housing 2, and the first electrical control housing 3 can be connected and fixed to the first motor housing 1 and the second motor housing 2. After the first electrical control housing 3, the first motor housing 1, the second motor housing 2 and other mechanical components of the motor pump are all assembled, the second electrical control housing 4 can be fastened to the top of the first electrical control housing 3 to close the third mounting cavity.

[0078] In one exemplary embodiment of this disclosure, reference is made to Figure 2 As shown, the first electronic control housing 3 and the second electronic control housing 4 are sealed together. For example, a fourth seal 54 is provided between the first electronic control housing 3 and the second electronic control housing 4. In other exemplary embodiments, the first electronic control housing 3 and the second electronic control housing 4 can also be sealed with a sealant, which will not be described in detail here.

[0079] In one exemplary embodiment of this disclosure, reference is made to Figure 5 As shown, the electric pump may further include a first pump housing 61 and a second pump housing 62. The first pump housing 61 may be installed on the side of the first motor housing 1 away from the second motor housing 2, i.e., on the outer side of the first motor housing 1 in a first direction; the second pump housing 62 may be installed on the side of the second motor housing 2 away from the first motor housing 1, i.e., on the outer side of the second motor housing 2 in a first direction. (Reference) Figure 1 As shown, the first pump housing 61 and the second pump housing 62 are located at opposite ends of the motor housing in a first direction. The first pump housing 61 can be used to mount the first gear pump, and the second pump housing 62 can be used to mount the second gear pump. The motor pump of this disclosure may further include a first motor, a second motor, and a controller. The first motor is mounted in the first motor housing 1, the second motor is mounted in the second motor housing 2, and the controller is mounted in the electrical control housing.
