The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted. In addition, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0038] Unless otherwise specified or explained, the technical terms or scientific terms used in the present disclosure shall have the common meanings understood by people with ordinary skills in the field to which the present disclosure belongs. The terms "one", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to indicate an open-ended inclusion and mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms "first" and "second" are used only as labels and are not used to limit the quantity, importance or order of their objects.

[0039] The terms "connected", "fixed", etc. should be understood in a broad sense. For example, "connected" 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.

[0040] In the description of the present disclosure, it should be understood that the terms "inside / outside", "height", "longitudinal / lateral", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present disclosure.

[0041] The present invention provides a motor pump, referring to Figures 1 to 5 As shown, it includes a motor housing and an electric control housing 3, the motor housing includes a first motor housing 1 and a second motor housing 2 arranged at intervals along a first direction; the first motor housing 1 has a first installation cavity open toward the second motor housing 2, and the second motor housing 2 has a second installation cavity open toward the first motor housing 1; the electric control housing 3 includes a main body 31 and a docking portion 32 arranged on one side of the main body 31 in the second direction; the main body 31 is stacked on the first motor housing 1 and the second motor housing 2 along the second direction; the docking portion 32 is located between the first motor housing 1 and the second motor housing 2; a third installation cavity 33 is formed in the main body 31, and a wiring cavity 34 is formed in the docking portion 32, the wiring cavity 34 is connected to the third installation cavity 33 in the second direction, and the wiring cavity 34 is open on both sides of the first direction to be connected to the first installation cavity and the second installation cavity respectively, the first direction is along the axial direction of the motor housing, and the first direction is perpendicular to the second direction.

[0042] The motor pump provided by the present disclosure has a first installation cavity that can be used to install the first motor; a second installation cavity that can be used to install the second motor, and a third installation cavity 33 that can be used to install the controller. When the motor housing is connected to the electric control housing 3, the controller in the third installation cavity 33 can be electrically connected to the first motor in the first motor housing 1 and the second motor in the second motor housing 2 through the two side openings of the wiring cavity 34 facing the first direction. The electrical connection between the controller and the two motors can be independent of each other, and the wiring does not affect each other, thereby increasing the difficulty of assembling the motor pump and reducing the failure rate of the wiring harness. Since the docking portion 32 is located between the first motor housing 1 and the second motor housing 2, the wiring cavity 34 in the docking portion 32 is connected to the first installation cavity and the second installation cavity through the two side openings in the first direction, respectively, so that the two docking parts of the electric control housing 3 and the first motor housing 1 and the second motor housing 2 can be isolated, thereby simplifying the joint structure of the docking point between the electric control housing and the motor housing, reducing the difficulty of sealing, and making it easier to achieve full sealing, thereby helping to improve the sealing of the motor pump and reduce costs.

[0043] Next, the motor pump of the present disclosure is further described in conjunction with the accompanying drawings. In the exemplary embodiment of the present disclosure, for ease of description, the axial direction of the motor pump, that is, the axial direction of the motor, is taken as the first direction / X direction, and two orthogonal directions in a plane perpendicular to the first direction are taken as the second direction / Z direction and the third direction / Y direction. Figure 1 As shown, the main body 31 is stacked in the direction of the first motor housing 1 and the second motor housing 2, that is, Figure 1 The height direction / Z direction in is used as the second direction.

[0044] It should be noted that, due to the upper limit of the precision of the manufacturing process, the two directions of "vertical" described in the present disclosure may not be 90° without error. For example, "vertical" may refer to a state where the angle formed by two straight lines is greater than 80° and less than 100°. As long as it is within the error range allowed by the manufacturing precision, it should be regarded as vertical. Therefore, it can be further explained that the concepts such as "coplanar", "same", and "symmetrical" mentioned in the present disclosure are all within the range allowed by the manufacturing process precision. In addition, also due to the limitations of the process, the "seal" described in the present disclosure may not be an ideal sealing condition. For example, air leakage may also occur between the two parts of the "sealed connection". The "sealed connection" described in the present disclosure may refer to the use of sealing means for connection. Those skilled in the art can understand that the "seal" mentioned in the present disclosure should be within the range allowed by the manufacturing and assembly process precision.

[0045] In an exemplary embodiment of the present disclosure, reference Figure 4 , Figure 5 As shown, Figure 4 shows a schematic diagram of the electric control housing 3, Figure 5 A schematic cross-sectional view of the electric control housing 3 along the XZ plane is shown.

[0046] Exemplarily, the docking portion 32 has a third through hole 321 facing the first motor housing 1, the first installation cavity is connected to the third installation cavity 33 through the third through hole 321, the controller is connected to the first motor through the first wiring harness, and the first wiring harness can be routed to the wiring cavity 34 through the third through hole 321. Correspondingly, the docking portion 32 can also have a sixth through hole 323 facing the second motor housing 2, the second installation cavity is connected to the third installation cavity 33 through the sixth through hole 323, the controller is connected to the second motor through the second wiring harness, and the second wiring harness can be routed to the wiring cavity 34 through the sixth through hole 323. Exemplarily, refer to Figure 5 As shown, the third through hole 321 is communicated with the sixth through hole 323 , and the first installation cavity is communicated with the second installation cavity through the wiring cavity 34 .

[0047] For example, refer to Figure 2 , Figure 3 As shown, Figure 3 The schematic diagram of the first motor housing 1 is exemplarily shown. The first motor housing 1 has a first through hole 12 facing the second motor housing 2, the first through hole 12 is connected to the first installation cavity, and the first through hole 12 is matched with the third through hole 321 to achieve the connection between the first installation cavity and the wiring cavity 34.

[0048] Exemplarily, the first motor housing 1 is sealed to the docking portion 32, so that the first installation cavity and the wiring cavity 34 are sealed, and the first installation cavity and the third installation cavity 33 are sealed to prevent water vapor, impurities, etc. from entering the first motor housing 1 and the electric control housing 3. Figure 2 , Figure 3 As shown, the first motor housing 1 is provided with a first mounting surface 11 at one end facing the docking portion 32, and the first mounting cavity is opened on the first mounting surface 11 to form a first through hole 12; Figure 5 As shown, the docking portion 32 has a first side surface 322 facing the first motor housing 1, and the third through hole 321 is opened on the first side surface 322; the first side surface 322 is sealedly connected to the first mounting surface 11, and the first through hole 12 is aligned with the third through hole 321. The first motor housing 1 and the docking portion 32 can be fixed by means of threaded connectors, adhesive, etc., as long as the connection between the first motor housing 1 and the docking portion 32 is achieved.

[0049] In an exemplary embodiment of the present disclosure, the first motor housing 1 and the docking portion 32 are sealed and connected by a sealing adhesive. The first side surface 322 and / or the first mounting surface 11 are coated with a sealing adhesive, and the first side surface 322 is at least partially attached to the first mounting surface 11 to form a closed-shaped sealing area. The shape of the sealing area can be substantially consistent with the shape of the coated sealing adhesive, and the first through hole 12 and the third through hole 321 are within the inner contour of the sealing area, so that the first through hole 12 and the third through hole 321 are sealed. It should be noted that the "closed-shaped sealing area" and "the hole is within the inner contour of the sealing area" described in the present disclosure refer to the sealing between the first motor housing 1 and the docking portion 32 at least in the area where the opening is docked, for example, the outer periphery of the area where the first through hole 12 and the third through hole 321 are matched is sealed to ensure that the entire outer periphery of the area where the first through hole 12 and the third through hole 321 are matched is airtight.

[0050] In another exemplary embodiment of the present disclosure, the first motor housing 1 and the docking portion 32 are sealed and connected by a sealing member. Figure 2 As shown, a first sealing member 41 is provided between the first mounting surface 11 and the first side surface 322 . The first sealing member 41 may be a sealing ring, a sealing gasket, or the like.

[0051] For example, the first sealing member 41 is a sealing gasket, and the first side surface 322 is at least partially in contact with the first mounting surface 11, clamping the first sealing member 41 to form a closed sealing area. The shape of the sealing area can be substantially consistent with the shape of the sealing gasket, and the first through hole 12 and the third through hole 321 are within the inner contour of the sealing area, so that the first through hole 12 and the third through hole 321 are sealed.

[0052] For another example, the first sealing member 41 is a sealing ring, referring to Figure 2 As shown, the first mounting surface 11 and / or the first side surface 322 has a first sealing groove 42, and the first sealing member 41 is sleeved in the first sealing groove 42; the first mounting surface 11 and the first side surface 322 are at least partially in contact with each other to compress the first sealing member 41, thereby forming a sealing area. The shape of the sealing area may be substantially consistent with the shapes of the first sealing groove 42 and the first sealing member 41, and the first through hole 12 and the third through hole 321 are within the inner contour of the sealing area, so that the first through hole 12 and the third through hole 321 are sealed when they are aligned.

[0053] In an exemplary embodiment of the present disclosure, reference Figure 3 As shown, the first mounting surface 11 is further provided with a second through hole 13, the second through hole 13 is spaced apart from the first through hole 12, and the second through hole 13 is connected to the first mounting cavity. Figures 2 to 5As shown, the second through hole 13 is also connected to the third through hole 321. That is, the first motor housing 1 has the first through hole 12 and the second through hole 13 facing the second motor housing 2, and the third through hole 321 can be connected to the first through hole 12 and the second through hole 13 at the same time, so as to realize the connection between the first installation cavity and the wiring cavity 34.

[0054] Exemplarily, the first through hole 12 and the second through hole 13 can be used to pass different wiring harnesses respectively. For example, a first motor high-voltage wiring harness is connected between the first motor and the controller, and the first motor high-voltage wiring harness led by the controller passes through the third installation cavity 33 and the wiring cavity 34 in sequence, passes through the third through hole 321 and the second through hole 13, enters the first installation cavity and is connected to the first motor. A first motor position signal wiring harness is connected between the first motor and the controller, and the first motor position signal wiring harness led by the controller passes through the third installation cavity 33 and the wiring cavity 34 in sequence, passes through the third through hole 321 and the first through hole 12, enters the first installation cavity and is connected to the first motor. For another example, other signal wiring harnesses between the first motor and the controller also pass through the first through hole 12. This exemplary embodiment can separate the channel through which the wiring harness between the first motor and the controller passes, for example, separating the first motor high-voltage wiring harness channel from the first motor position signal channel, avoiding electromagnetic interference between the wiring harnesses, and facilitating the precise control of the motor pump. In addition, the separation of the wiring harness channel between the first motor and the controller is also conducive to making the wiring harness between the controller and the first motor more neat and organized, which is conducive to avoiding misinstallation and reducing the failure rate.

[0055] In an exemplary embodiment of the present disclosure, reference Figure 3 As shown, the first through hole 12 and the second through hole 13 are both arranged within the inner contour of the sealing area, so that the sealing area simultaneously seals the first through hole 12 and the third through hole 321, and the second through hole 13 and the third through hole 321. This exemplary embodiment can simplify the sealing structure between the first motor housing 1 and the docking portion 32, which is conducive to improving the sealing performance.

[0056] For example, reference Figure 2 , Figure 3 As shown, a first seal 41 is provided between the first mounting surface 11 and the first side surface 322, and the first seal 41 is sleeved in the first sealing groove 42 of the first mounting surface 11 and / or the first side surface 322, and the first through hole 12, the second through hole 13, and the third through hole 321 are all provided within the inner contour of the first seal 41. The sealing area formed by pressing the first mounting surface 11 and the first side surface 322 to form the first seal 41 can simultaneously seal the connection between the first through hole 12 and the third through hole 321, and the connection between the second through hole 13 and the third through hole 321, which is conducive to simplifying the sealing structure, reducing the number of seals, reducing the sealing failure rate, and improving the sealing effect.

[0057] The connection between the second motor housing 2 and the docking portion 32 can refer to the above exemplary description of the connection between the first motor housing 1 and the docking portion 32. Figure 2 , Figure 3 As shown, the structure of the second motor housing 2 can be similar to that of the first motor housing 1, for example, symmetrical with the first motor housing 1, or the same as the structure of the first motor housing 1. The second motor housing 2 has a seventh through hole facing the first motor housing 1, and the seventh through hole is connected to the second installation cavity. The seventh through hole is aligned with the sixth through hole 323 to achieve communication between the second installation cavity and the wiring cavity 34.

[0058] The second motor housing 2 and the docking portion 32 can also be sealed and connected, so that the second installation cavity and the wiring cavity 34 are sealed, and the second installation cavity and the third installation cavity 33 are sealed to prevent water vapor, impurities, etc. from entering the second motor housing 2 and the electric control housing 3. Reference can be made to the aforementioned exemplary description of the sealed connection between the first motor housing 1 and the docking portion 32. The second motor housing 2 can be provided with a fourth installation surface at one end facing the docking portion 32, and the second installation cavity opens on the fourth installation surface to form a seventh through hole. The docking portion 32 has a second side facing the second motor housing 2, the sixth through hole 323 is opened on the second side, the second side is sealed and connected with the fourth installation surface, and the seventh through hole is aligned with the sixth through hole 323. The second motor housing 2 and the docking portion 32 can be fixed by means of threaded connectors, adhesives, etc., as long as the connection between the second motor housing 2 and the docking portion 32 is achieved.

[0059] Exemplarily, the second motor housing 2 and the docking portion 32 may be sealed and connected by a sealing adhesive. The second side surface and / or the fourth mounting surface are coated with a sealing adhesive, and the second side surface is at least partially attached to the fourth mounting surface to form a second sealing area with a closed shape. The shape of the second sealing area may be substantially consistent with the shape of the coated sealing adhesive, and the seventh through hole and the sixth through hole 323 are within the inner contour of the second sealing area, so that the seventh through hole and the sixth through hole 323 are sealed.

[0060] In another exemplary embodiment of the present disclosure, the second motor housing 2 and the docking portion 32 are sealed and connected by a sealing member. Figure 2 As shown, a second sealing member 43 is provided between the second side surface and the fourth mounting surface. The second sealing member 43 may be a sealing ring, a sealing gasket, etc.

[0061] In an exemplary embodiment of the present disclosure, the fourth mounting surface is further provided with an eighth through hole, the eighth through hole is spaced apart from the seventh through hole, and the eighth through hole is connected to the second mounting cavity. The eighth through hole is also connected to the sixth through hole 323. That is, the second motor housing 2 has the seventh through hole and the eighth through hole facing the first motor housing 1, and the sixth through hole 323 can be connected to the seventh through hole and the eighth through hole at the same time, so as to realize the connection between the second mounting cavity and the wiring cavity 34.

[0062] The seventh through hole and the eighth through hole can be used to pass different wiring harnesses respectively. For example, a second motor high-voltage wiring harness is connected between the second motor and the controller, and the second motor high-voltage wiring harness drawn by the controller passes through the third installation cavity 33 and the wiring cavity 34 in sequence, passes through the sixth through hole 323 and the eighth through hole to enter the second installation cavity and is connected to the second motor. A second motor position signal wiring harness is connected between the second motor and the controller, and the second motor position signal wiring harness drawn by the controller passes through the third installation cavity 33 and the wiring cavity 34 in sequence, passes through the sixth through hole 323 and the seventh through hole, enters the second installation cavity and is connected to the second motor. For another example, other signal wiring harnesses between the second motor and the controller also pass through the seventh through hole. This exemplary embodiment can separate the channel through which the wiring harness between the second motor and the controller passes, for example, separating the second high-voltage wiring harness channel of the motor from the second motor position signal channel, avoiding electromagnetic interference between the wiring harnesses, and facilitating the precise control of the motor pump. In addition, the separation of the wiring harness channel between the second motor and the controller is also conducive to making the wiring harness routing between the controller and the second motor more neat and orderly, which is conducive to avoiding misinstallation and reducing the failure rate.

[0063] In an exemplary embodiment of the present disclosure, reference Figure 3 As shown, similar to the first motor housing 1, the seventh through hole and the eighth through hole are both arranged within the inner contour of the second sealing area, so that the second sealing area simultaneously seals the seventh through hole and the sixth through hole 323, and the eighth through hole and the sixth through hole 323. This exemplary embodiment can simplify the sealing structure between the second motor housing 2 and the docking portion 32, which is conducive to improving the sealing performance.

[0064] In the exemplary embodiment of the present disclosure, the first motor housing 1 and the second motor housing 2 are split structures, the first mounting surface 11, the first side surface 322, the fourth mounting surface, and the second side surface are all perpendicular to the axis X direction of the motor, and the first motor housing 1 and the second motor housing 2 are respectively docked with the two sides of the docking portion 32 in the X direction. This embodiment can realize the independent installation of the first motor and the second motor, which is conducive to improving the installation efficiency and accuracy, and the processing difficulty of the motor housing is lower, and the assembled motor pump has better centering and better performance.

[0065] In an exemplary embodiment of the present disclosure, reference Figure 2 , Figure 3As shown, the first motor housing 1 also has a second mounting surface 14, and the main body 31 is stacked on the second mounting surface 14 along the Z direction. The second mounting surface 14 is provided with a fourth through hole 141. Figure 5 As shown, a fifth through hole 311 is formed on the bottom surface of the main body 31 stacked on the second mounting surface 14 ; the fifth through hole 311 corresponds to the fourth through hole 141 , so that the third mounting cavity 33 is connected to the first mounting cavity.

[0066] Exemplarily, the fifth through hole 311 and the fourth through hole 141 are also used for routing between the first motor and the controller. For example, a first motor low-voltage wiring harness is connected between the first motor and the controller, and the first motor low-voltage wiring harness is led out from the first motor of the first installation cavity, passes through the fourth through hole 141 and the fifth through hole 311 in sequence, enters the third installation cavity 33, and is connected to the controller. The first motor low-voltage wiring harness can be used to transmit the pump head oil pressure signal of the first motor and the pump connected to the first motor. This exemplary embodiment can separate the channel through which the wiring harness between the first motor and the controller passes, for example, separating the first motor high-voltage wiring harness channel from the first motor low-voltage wiring harness channel, avoiding electromagnetic interference between the wiring harnesses, and facilitating precise control of the motor pump.

[0067] In an exemplary embodiment, a first motor low-voltage wiring harness, a first motor high-voltage wiring harness, and a first motor position signal wiring harness are connected between the first motor and the controller. The above three wiring harnesses are respectively routed through the fourth through hole 141 and the fifth through hole 311, the second through hole 13 and the third through hole 321, and the first through hole 12 and the third through hole 321, and are separated from each other.

[0068] Exemplarily, the fourth through hole 141 is sealed and connected with the fifth through hole 311, so that the first installation cavity and the third installation cavity 33 are sealed to prevent water vapor, impurities, etc. from entering the first motor housing 1 and the electronic control housing 3. The first motor housing 1 and the electronic control housing 3 can be fixed by threaded connectors, adhesives, etc., as long as the connection between the first motor housing 1 and the electronic control housing 3 is achieved. For example, referring to Figure 1 , Figure 2 As shown, the electric control housing 3 is connected to the first motor housing 1 through the third connecting member 6. The side of the main body 31 may be provided with a receiving cavity 312 for receiving the third connecting member 6. When the main body 31 of the electric control housing 3 is connected to the first motor housing 1 through the third connecting member 6, the third connecting member 6 may pass through the connecting hole on the main body 31 from top to bottom in the receiving cavity 312 and be screwed into the second mounting surface 14 of the first motor housing 1. Exemplarily, the third connecting member 6 is a connecting bolt.

[0069] In an exemplary embodiment of the present disclosure, a sealing adhesive is used to seal the first motor housing 1 and the main body 31. The second mounting surface 14 and / or the bottom surface of the main body 31 stacked on the second mounting surface 14 are coated with a sealing adhesive, and the first motor housing 1 and the main body 31 are at least partially attached to each other, so that the fourth through hole 141 and the fifth through hole 311 are sealed.

[0070] In another exemplary embodiment of the present disclosure, the first motor housing 1 and the main body 31 are sealed and connected by a seal. Figure 2 As shown, a third sealing member 44 is provided between the second mounting surface 14 and the bottom surface of the main body 31 . The third sealing member 44 may be a sealing ring, a sealing gasket, or the like.

[0071] For example, the second mounting surface 14 and / or the bottom surface of the main body 31 has a second sealing groove, and the third sealing member 44 is sleeved in the second sealing groove; the second mounting surface 14 and the bottom surface of the main body 31 are at least partially in contact with each other to compress the third sealing member 44 and seal the fourth through hole 141 and the fifth through hole 311.

[0072] For example, reference Figure 2 , Figure 3 As shown, the second motor housing 2 also has a third mounting surface 21, and the main body 31 is stacked on the third mounting surface 21 along the Z direction. The third mounting surface 21 is provided with a ninth through hole 23, referring to Figure 5 As shown, a tenth through hole 313 is formed on the bottom surface of the main body 31 stacked on the third mounting surface 21 , and the ninth through hole 23 corresponds to the tenth through hole 313 , so that the third mounting cavity 33 is connected to the second mounting cavity.

This exemplary embodiment can separate the channel through which the wiring harness between the second motor and the controller passes, for example, separating the second motor high-voltage wiring harness channel from the second motor low-voltage wiring harness channel, avoiding electromagnetic interference between the wiring harnesses, and facilitating precise control of the motor pump.

[0074] In an exemplary embodiment of the present disclosure, the third mounting surface 21 is coplanar with the second mounting surface 14 , so that after the electronic control housing 3 is mounted on the motor housing, the main body 31 is stably stacked on the first motor housing 1 and the second motor housing 2 .

[0077] The connection between the second motor housing 2 and the electric control housing 3 can refer to the connection between the first motor housing 1 and the electric control housing 3, for example, Figure 1 , Figure 2 As shown, the electric control housing 3 is connected to the second motor housing 2 via the third connecting member 6. When the main body 31 of the electric control housing 3 is connected to the second motor housing 2 via the third connecting member 6, the third connecting member 6 can pass through the connecting hole on the main body 31 from top to bottom in the accommodating cavity 312 and be screwed into the third mounting surface 21 of the second motor housing 2.

[0078] The sealing between the ninth through hole 23 and the tenth through hole 313 can refer to the sealing between the fourth through hole 141 and the fifth through hole 311, for example, the second motor housing 2 and the main body 31 are sealed and connected by a sealing adhesive, or the second motor housing 2 and the main body 31 are sealed and connected by a sealing member. Figure 2 As shown, a fourth sealing member 45 is provided between the third mounting surface 21 and the bottom surface of the main body 31 . The fourth sealing member 45 may be a sealing ring, a sealing gasket, or the like.

[0079] For example, the third mounting surface 21 and / or the bottom surface of the main body 31 has a third sealing groove, and the fourth sealing member 45 is sleeved in the third sealing groove; the third mounting surface 21 and the bottom surface of the main body 31 are at least partially in contact with each other to compress the fourth sealing member 45 to seal the ninth through hole 23 and the tenth through hole 313.

Exemplarily, at least one fifth through hole 311 and the fourth through hole 141 are used for routing between the first motor and the controller. For example, the first motor low-voltage wire harness and the first motor high-voltage wire harness are connected between the first motor and the controller, and the wires are routed through two groups of the fifth through holes 311 and the fourth through holes 141 respectively.

This exemplary embodiment can separate the channel through which the wiring harness between the second motor and the controller passes, for example, separates the second motor low-voltage wiring harness from the second motor high-voltage wiring harness channel, avoids electromagnetic interference between the wiring harnesses, and is conducive to the precise control of the motor pump.
