[0033] In the suspension system of a vehicle, an electric motor pump is usually used to drive a shock absorber, and a sensor is provided in the hydraulic chamber of the electric motor pump to detect the temperature or pressure of the oil. In the related art, the signal wire of the sensor is built into the motor installation chamber for installing the motor and enters the electronic control chamber from the motor installation chamber to be electrically connected to the controller; it is easy for the oil to enter the electronic control chamber along the routing path of the signal wire. If a sealing bushing is used to isolate the oil between the motor rotor and the stator, the bushing will increase the cost; if a sealing ring is used to seal the contact position between the signal wire and the electronic control chamber, the sealing is extremely difficult and the effect is not good.

[0034] Based on the above problems, the present utility model proposes an electric motor pump module 100.

[0035] With reference to Figures 1 to 4 , in an embodiment of the present utility model, the electric motor pump module 100 includes a drive motor 1, a control unit 4, and a hydraulic pump 2. The drive motor 1 has a motor housing 11, and the motor housing 11 is provided with a line channel 114; the control unit 4 is located outside the motor housing 11; the hydraulic pump 2 is provided at one end of the drive motor 1 and is connected to the drive motor 1. A signal detection unit is configured in the hydraulic pump 2. The signal detection unit includes a sensor (not shown) and a signal wire 3. The signal wire 3 passes through the line channel 114 and is electrically connected to the control unit 4.

[0036] The motor pump module 100 is a device that combines a driving motor 1 and a hydraulic pump 2, using the mechanical energy of the driving motor 1 to drive the hydraulic pump 2 so that the hydraulic pump 2 sucks in and discharges liquid. The motor housing 11 of the driving motor 1 is provided with a motor installation cavity 113 and a circuit channel 114. The motor installation cavity 113 has two ends arranged at intervals and at least one end is open. The stator and rotor of the driving motor 1 are installed in the motor installation cavity 113, and the output shaft of the rotor can be connected to the hydraulic pump 2 through the end opening of the motor housing 11. The circuit channel 114 is located outside the motor installation cavity 113; the circuit channel 114 can be arranged in the side wall enclosing the motor installation cavity 113; alternatively, the motor housing 11 can include a housing main body 111 and a wire-passing structure 112 protruding from the outer wall of the housing main body. The motor installation cavity 113 is provided in the housing main body 11, and the circuit channel 114 is arranged in the wire-passing structure 112.

[0037] The hydraulic pump 2 is connected to the end of the motor housing 11. The hydraulic pump 2 includes a pump housing 21 and a pump body (not shown) arranged in the pump housing 21. The pump housing 21 is provided with a hydraulic cavity and is provided with a liquid inlet and a liquid outlet communicating with the hydraulic cavity. The driving motor 1 drives the pump body to move so that liquid enters and exits the hydraulic cavity; optionally, the hydraulic pump 2 is set as a gear pump, the pump body is set as an impeller and is connected to the output shaft of the driving motor 1, and the driving motor 1 drives the impeller to rotate to suck in and discharge oil.

[0038] The motor pump module 100 further includes a control unit 4. The control unit 4 is arranged outside the motor housing 11. Optionally, the control unit 4 includes a controller housing 41 connected to the motor housing 11 and a controller (not shown) arranged in the controller housing 41. The controller housing 41 is used to form an electric control cavity for installing the controller. An electric control cavity can be provided in the controller housing 41, or the controller housing 41 and the motor housing 11 can enclose to form an electric control cavity. The controller is arranged in the electric control cavity and is electrically connected to the driving motor 1 for controlling the operating state of the driving motor 1. The controller can be set as a circuit board integrated with electrical components and / or devices, or can be set as other structures.

[0039] The hydraulic pump 2 is configured with a signal detection unit. The signal detection unit includes a sensor and a signal line 3 connecting the sensor. The sensor is disposed in the hydraulic chamber of the hydraulic pump 2. The sensor can be set as one of a pressure sensor, a temperature sensor, and a pressure and temperature sensor, and is used to detect the temperature and / or pressure of the oil in the hydraulic chamber. Optionally, two sensors can be disposed in the hydraulic chamber to respectively detect the oil states at the liquid inlet and the liquid outlet. The signal line 3 is used for electrically connecting to the control unit 4 and can transmit the detection signal measured by the sensor to the control unit 4 for signal processing. The control unit 4 can control the operating state of the drive motor 1 according to the detection information. The signal line 3 passes through the line channel 114 of the motor housing 11 to extend to the position of the control unit 4 and is electrically connected to the control unit 4. Since the line channel 114 is isolated from the motor installation cavity 113, the line channel 114 is in a state of isolating the oil, which can prevent the oil from flowing through the line channel 114 to the electric control cavity, and there is no need to provide a complex sealing structure between the line channel 114 and the electric control cavity, reducing the sealing difficulty in the motor pump module 100.

[0040] That is, the technical solution of the present utility model passes through the line channel 114 isolated from the motor installation cavity 113 in the motor housing 11, and the signal line 3 connected to the sensor can pass through the line channel 114 to be connected to the control unit 4. With this setting method, it is possible to prevent the signal line 3 from passing through the motor installation cavity 113, and the line channel 114 isolates the oil, which can prevent the oil from flowing along the line channel 114 to the electric control cavity of the control unit 4. Therefore, there is no need to provide a complex sealing structure in the motor pump module 100, reducing the sealing difficulty in the motor pump module 100.

[0041] In an embodiment, the hydraulic pump 2 has a pump housing 21. The pump housing 21 is provided with a hydraulic chamber and an external channel communicating with the hydraulic chamber. At least part of the structure of the sensor is located in the hydraulic chamber, and the signal line 3 passes through the external channel and extends to the line channel 114.

[0042] In this embodiment, the hydraulic pump 2 includes a pump housing 21 and a pump body (not shown) disposed in the pump housing 21. The pump housing 21 is provided with a hydraulic chamber and an external channel. The hydraulic chamber has two openings. The drive motor 1 drives the pump body to move so that the liquid enters and exits the hydraulic chamber. Optionally, the hydraulic pump 2 is set as a gear pump, and the pump body is set as an impeller connected to the output shaft of the drive motor 1. The drive motor 1 drives the impeller to rotate to suck in and discharge the oil.

[0043] At least part of the structure of the sensor is arranged in the hydraulic chamber for detecting the oil state in the hydraulic chamber. Optionally, the sensor can be arranged at one of the opening positions of the hydraulic chamber, or sensors can be respectively arranged at the two openings of the hydraulic chamber to respectively detect the oil states entering and discharging from the hydraulic chamber. The external channel is used for the signal line 3 to pass through, which can guide the routing direction of the signal line 3 and play a role in limiting the signal line 3. After the signal line 3 passes through the external channel, it enters the line channel 114 of the motor housing 11 and extends along the line channel 114 to the position of the control unit 4 for electrical connection with the control unit 4.

[0044] Optionally, part of the structure of the sensor can be located in the external channel, and a sealing ring can be arranged between the inner wall of the external channel and the sensor to improve the sealing performance and prevent the liquid in the hydraulic chamber from leaking out through the external channel. Additionally, a sealing ring can also be arranged between the inner wall of the external channel and the signal line 3 to improve the sealing performance.

[0045] In an embodiment, the opening at the end of the external channel far from the hydraulic chamber is coaxial with the line channel 114. In this setting, the signal line 3 can directly enter the line channel 114 without bending after extending out of the external channel, which can not only shorten the wiring distance, reduce the length of the signal line 3 and the complexity of signal line 3 wiring, but also avoid the signal line 3 being easily damaged or affecting signal transmission due to bending of the signal line 3.

[0046] In an embodiment, the line channel 114 extends along the axial direction of the motor housing 11.

[0047] In this embodiment, one opening of the line channel 114 is adjacent to the hydraulic pump 2, and the line channel 114 extends along the axial direction of the drive motor 1, that is, the length direction of the motor housing 11, which can reduce the threading difficulty of the signal line 3 and also reduce the manufacturing difficulty of the motor housing 11. Optionally, when the motor pump module 100 is provided with two drive motors 1, the end of the line channel 114 communicating with the electric control cavity is located on the side far from the hydraulic pump 2, and the line channels 114 of the two drive motors 1 can be interconnected, so that the signal lines 3 in the two drive motors 1 can be electrically connected to the controller at the same position, which can reduce the sealing difficulty and improve the wiring convenience.

[0048] Combined with reference to Figures 2 to 4 , in an embodiment, the signal detection unit is provided with two sensors and two signal lines, the hydraulic pump 2 is provided with two external channels, the motor housing 11 is provided with two line channels 114, and one signal line 3, one sensor, one external channel and one line channel 114 are correspondingly arranged.

[0049] In this embodiment, two sensors are arranged in the hydraulic cavity, and the two sensors can be used to detect the oil fluid states of the two openings of the hydraulic cavity respectively. Optionally, the two sensors can be the same sensors or different sensors. For example, both of the two sensors can be set as pressure sensors, or both can be set as temperature sensors or pressure-temperature sensors. It is also possible that one of the two sensors is one of a pressure sensor, a temperature sensor, and a pressure-temperature sensor, and the other is another one of a pressure sensor, a temperature sensor, and a pressure-temperature sensor.

[0050] The pump housing 21 of the hydraulic pump 2 is provided with two external channels, and two line channels 114 are arranged in the motor housing 11. The signal lines 3 respectively connected to the sensors pass through one external channel and one line channel 114, and thus extend to the electric control cavity to be electrically connected to the control unit 4 respectively. This setting method is convenient for distinguishing the signal lines 3 of the two sensors so as to accurately connect the wires, and accurately obtain the detection signals measured by the sensors in different detection areas.

[0051] Please refer to Figure 2 and Figure 3 , in an embodiment, the motor housing 11 includes a housing main body 111 and a wire-passing structure 112 protruding from the outside of the housing main body 111. The housing main body 111 is provided with a motor installation cavity 113, and the wire-passing structure 112 is provided with a line channel 114.

[0052] With this setting method, through the setting of the wire-passing structure 112, it is ensured that there is a relatively large structural space for arranging the line channel 114, and it is also avoided that the side wall structural strength of the housing main body 111 is reduced due to the setting of the line channel 114, ensuring that the motor housing 11 has good structural strength.

[0053] Please refer to Figure 4 , in an embodiment, the pump housing 21 includes a pump housing main body 211 and an external structure 212 protruding from the outside of the pump housing main body 211. The pump housing main body 211 is provided with a hydraulic cavity, and the external structure 212 extends in the direction close to the line channel 114, and an external channel is arranged in the external structure 212.

[0054] With this setting method, through the setting of the external structure 212, the opening of the external channel is close to the line channel 114, so that after the signal line 3 extends out from the external channel, it can directly enter the line channel 114, simplifying the circuit, avoiding the complicated routing of the signal line 3, and improving the convenience of circuit layout.

The controller housing 41 is provided with an electric control cavity, and the controller is located in the electric control cavity.

[0056] In this embodiment, the control unit 4 includes a controller housing 41 connected to the motor housing 11 and a controller disposed in the controller housing 41. The controller housing 41 is used to form an electric control cavity for installing the controller. An electric control cavity can be provided in the controller housing 41, or the controller housing 41 and the motor housing 11 can enclose to form an electric control cavity. The controller is disposed in the electric control cavity and is electrically connected to the drive motor 1 to control the operating state of the drive motor 1.
