According to the hydraulic energy supply device of the utility model, it may include a motor 110 pump assembly, a motor controller 150 and a radiator. The motor 110 pump assembly may include a hydraulic pump 100 and a motor 110 for driving the hydraulic pump 100. The number of hydraulic pumps 100 and motors 110 of the motor 110 pump assembly may be one, two or other numbers. For example, two motors 110 and two hydraulic pumps 100 may form a motor 110 pump assembly. The power of the motor 110 pump assembly may be greater than 8KW, such as 9KW. Take the motor 110 pump assembly including two motors 110 as an example. The two motors 110 may be respectively recorded as a first motor 110 and a second motor 110. The first motor 110 includes a first winding body and a first lead wire. The second motor 110 includes a second winding body and a second lead wire. The motor controller 150 is arranged on the outer side of the motor 110 along the third direction D3. When the hydraulic power supply device is installed on the vehicle, the third direction D3 can be consistent with the height direction of the vehicle, and the motor controller 150 can be located above the motor 110. The radiator is located between the motor 110 and the motor controller 150, and is thermally connected to the motor 110 and the motor controller 150. The radiator is used to conduct the heat of the motor controller 150 to achieve the purpose of cooling the motor controller 150. The motor 110 and the motor controller 150 can constitute a motor 110 assembly. The motor 110 may include a motor body 114 and a housing 111. The motor body 114 may include a stator and a rotor. The stator includes a stator winding and a stator core. The stator winding is connected to the stator core. The stator winding includes a winding body and a lead wire. The lead wire includes a root end and a tip end along its own length direction, that is, the two ends of the lead wire. The root end of the lead wire is connected to the winding body and fixed to the stator core. For example, the root end of the lead wire is wound around the stator core, or a junction bar is provided at one end of the winding connected to the lead wire. The lead wire is fixedly connected to the junction bar. Taking the three-phase motor 110 as an example, the three-phase motor 110 includes a three-phase winding and three lead wires corresponding to the three-phase winding. The three-phase winding is connected to the junction bar. The junction bar is connected to the three lead wires. In some examples, the three lead wires can be an integrated structure with the junction bar. The tip end of the lead wire is connected to the transfer copper bus.

[0101] According to the hydraulic energy supply device of the utility model, by setting a radiator between the motor 110 and the motor controller 150, the heat of the motor 110 and the motor controller 150 can be conducted, thereby helping to dissipate the heat of the motor controller 150 and further improving the operating efficiency of the motor controller 150.

[0102] First embodiment

[0103] See also Figures 1 to 9 According to the first embodiment of the utility model, a motor 110 pump assembly may include a hydraulic pump 100, a motor 110, a first sensor 131 and an adapter assembly 140. The motor 110 is connected to the hydraulic pump 100 to drive the hydraulic pump 100. The first sensor 131 is provided at the hydraulic pump 100. The adapter assembly 140 is provided at the motor 110. The adapter assembly 140 may include a first component 141 and a second component 142. The first end of the first component 141 is electrically connected to the first sensor 131. The first end of the second component 142 is detachably electrically connected to the second end of the first component 141. The second end of the second component 142 is suitable for being electrically connected to an external circuit. The external circuit here may be, for example, a motor controller 150, a control device of a vehicle, and the like.

[0104] According to the motor 110 pump assembly of the utility model, the first sensor 131 provided in the hydraulic pump 100 can be connected to the external circuit through the adapter component 140 provided in the motor 110. Moreover, the first component 141 and the second component 142 are detachably connected. This can save circuits and simplify the circuit structure between the sensor and the external circuit, facilitate installation and maintenance, and also help reduce the difficulty and cost of sealing.

[0105] The axial direction of the motor 110 pump assembly can be defined as a first direction D1. The motor 110 pump assembly also has a second direction D2 and a third direction D3 that are perpendicular to the first direction D1. The second direction D2 is perpendicular to the third direction D3.

[0106] See also Figures 1 to 4 Optionally, the hydraulic pump 100 may include a pump housing 101. The pump housing 101 and the housing 111 are detachably connected. One end of the housing 111 is an open port 112q. The pump housing 101 blocks the open port 112q. Here, the pump housing 101 is equivalent to an end cover of the motor 110. This is conducive to reducing the number of parts, simplifying the structure of the motor 110 pump assembly, and improving the compactness of the motor 110 pump assembly in the first direction D1.

[0107] See also Figures 1 to 4For example, the hydraulic pump 100 of the embodiment of the utility model can be a bidirectional pump. The hydraulic pump 100 has a first opening and a second opening that are connected to each other. The hydraulic oil can flow from the first opening to the second opening, or from the second opening to the first opening. In this regard, the motor 110 pump assembly of the utility model can also include a second sensor 132. The second sensor 132 is provided in the hydraulic pump 100. The first end of the first component 141 is electrically connected to the second sensor 132. The first sensor 131 is at least suitable for detecting the oil temperature at the first opening of the hydraulic pump 100. The second sensor 132 is at least suitable for detecting the oil temperature at the second opening of the hydraulic pump 100.

[0108] See also Figures 1 to 6 For example, the motor 110 may include a housing 111. The second component 142 is completely located inside the housing 111. Therefore, during the assembly of the motor 110, the second component 142 may be assembled into the housing 111 separately, so that the second component 142 and the motor 110 may be assembled and connected with the hydraulic pump 100 or the first component 141 as a whole. This facilitates the disassembly, assembly and maintenance of the second component 142. At the same time, the housing 111 may be used to better protect the second component 142.

[0109] Continue reading Figures 1 to 6 Further, the motor 110 may include a housing 111. The housing 111 is provided with a first connection hole 112e. The first connection hole 112e penetrates the housing 111. At least part of the second component 142 is located in the first connection hole 112e. The first end of the first component 141 is located in the first connection hole 112e. The second end of the first component 141 is located outside the first connection hole 112e. By arranging the second component 142 in the first connection hole 112e and using the first connection hole 112e to accommodate part of the first component 141, the housing 111 can be used to protect the second component 142 and the connection part between the second component 142 and the first component 141. At the same time, by providing the first connection hole 112e in the housing 111, at least part of the adapter component 140 can be accommodated, thereby reducing the occupation of the external space of the housing 111 by the adapter component 140, which is conducive to improving the structural compactness of the motor 110.

[0110] exist Figures 2 to 6 In the example shown, the first connection hole 112e penetrates the housing 111. Specifically, one end of the first connection hole 112e penetrates along the first direction D1 to the surface of the housing 111 facing the hydraulic pump 100, and the other end of the first connection hole 112e penetrates along the third direction D3 to the surface of the housing 111 facing the motor controller 150. That is, the first connection hole 112e is a curved through hole.

[0111] See also Figures 2 to 6In addition, the motor 110 pump assembly may further include a sealing sleeve 142d. Sealing sleeve 142d. The sealing sleeve 142d is located in the first connecting hole 112e. And the sealing sleeve 142d is coated on the outside of the adapter assembly 140. The sealing sleeve 142d is suitable for blocking the heat conduction between the housing 111 and the adapter assembly 140, and can also prevent the adapter assembly 140 from rubbing against the hole wall of the first connecting hole 112e. Specifically, by providing the sealing sleeve 142d, the adapter assembly 140 and the hole wall of the first connecting hole 112e can be separated, so that on the one hand, the adapter assembly 140 can be prevented from rubbing against the hole wall of the first connecting hole 112e, and on the other hand, hot air can be prevented from flowing into the motor 110, thereby preventing condensation.

[0112] See also Figures 2 to 4 For example, the first component 141 is plugged into the second component 142. By adopting the plug-in method to achieve the connection between the first component 141 and the second component 142, it is more convenient to disassemble and assemble, thereby improving the disassembly and assembly efficiency.

[0113] See also Figures 2 to 6 For example, the hydraulic pump 100 may include a pump housing 101. The pump housing 101 may include a second connection hole 101a and a third connection hole 101b. The first sensor 131 is installed in the second connection hole 101a. The second sensor 132 is installed in the third connection hole 101b. By providing the second connection hole 101a and the third connection hole 101b in the pump housing 101, the first sensor 131 and the second sensor 132 may be installed in the pump housing 101. This is conducive to improving the accuracy of detecting the oil temperature at the two openings of the hydraulic pump 100.

[0114] See also Figures 1 to 6In a hydraulic energy supply device having two motors 110 and two hydraulic pumps 100, the two motors 110 are respectively a first motor 110 and a second motor 110 which are coaxially and oppositely arranged. The first motor 110 includes a first housing 111. The second motor 110 includes a second housing 111. The first housing 111 and the second housing 111 are fixedly connected to each other or are constructed as an integral part. The two hydraulic pumps 100 are located at the outer ends of the two motors 110 and are coaxially arranged with the motors 110. The two hydraulic pumps 100 are respectively recorded as a first hydraulic pump 100 and a second hydraulic pump 100. The first hydraulic pump 100 is connected to the first motor 110. The second hydraulic pump 100 is connected to the second motor 110. The pump housing 101 of the first hydraulic pump 100 is a first pump housing 101. The pump housing 101 of the second hydraulic pump 100 is a second pump housing 101. The first pump housing 101 is provided with a second connecting hole 101a and a third connecting hole 101b. The second connection hole 101a is used to install the first sensor 131. The third connection hole 101b is used to install the second sensor 132. The second pump housing 101 is provided with the second connection hole 101a and the third connection hole 101b. The second connection hole 101a is used to install the first sensor 131. The third connection hole 101b is used to install the second sensor 132.

[0115] Optionally, the second connection hole 101a is parallel to the third connection hole 101b, so as to facilitate the processing of the second connection hole 101a and the third connection hole 101b and facilitate the assembly of the first sensor 131 and the second sensor 132.

[0116] In the illustrated example, the first connection hole 112 e and the second connection hole 101 a are both parallel to the first direction D1 of the hydraulic pump 100 .

[0117] Optionally, the first sensor 131 is a temperature sensor or a temperature and pressure sensor.

[0118] Optionally, the second sensor 132 is a temperature sensor or a temperature and pressure sensor.

[0119] Optionally, the first sensor 131 and the second sensor 132 may be sensors of the same model and specification, or sensors of different models and specifications.

[0120] See also Figures 2 to 4 For example, the first component 141 includes a sensor adapter plate 141a and a communication socket 141b. The sensor adapter plate 141a is fixedly connected to the communication socket 141b. In this way, the sensor adapter plate 141a and the communication socket 141b form a whole, thereby reducing the number of parts and facilitating more efficient assembly operations. The sensor adapter plate 141a is used to connect with the first sensor 131 and the second sensor 132. The communication socket 141b is used to connect with the second component 142.

[0121] In other examples, the sensor adapter plate 141a may be indirectly connected to the communication socket 141b via a cable.

[0122] Continue reading Figures 2 to 4 For example, at least one of the first sensor 131 and the second sensor 132 abuts against the sensor adapter plate 141a. It can be understood that the first sensor 131 abuts against the sensor adapter plate 141a, and the second sensor 132 is connected to the sensor adapter plate 141a in other ways. Or it can be understood that the first sensor 131 is connected to the sensor adapter plate 141a in other ways, and the second sensor 132 abuts against the sensor adapter plate 141a. Or it can be understood that both the first sensor 131 and the second sensor 132 abut against the sensor adapter plate 141a. This makes the installation operation of the sensor simpler and more convenient, which is beneficial to improving the assembly efficiency.

[0123] Further, a spring is provided at the end of at least one of the first sensor 131 and the second sensor 132. The spring abuts against the sensor adapter plate 141a. Either the first sensor 131 and the second sensor 132 abut against the sensor adapter plate 141a through the spring, or the first sensor 131 and the second sensor 132 abut against the sensor adapter plate 141a through the spring, respectively. In the installed state, the abutment between at least one of the first sensor 131 and the second sensor 132 and the sensor adapter plate 141a can be achieved by the preload force of the spring, thereby improving the reliability of the conductive connection, and further facilitating the prevention of poor contact due to factors such as bumps and vibrations.

[0124] See also Figures 2 to 9 For example, the housing 111 is formed with a cooling channel 111a. The cooling channel 111a is used to cool the motor 110 and the power device 152. The first connecting hole 112e and the cooling channel 111a are arranged at intervals. This prevents the coolant in the cooling channel 111a from contacting the first connecting hole 112e and causing a short circuit. The cooling channel 111a is arranged at intervals with the inner cavity enclosed by the housing 111 and the inner cavity of the hydraulic pump 100. In other words, the heat exchange medium flowing in the cooling channel 111a is different from the liquid in the motor 110 and the liquid in the hydraulic pump 100. In some examples, the cooling channel 111a can share a heat exchange medium with the air conditioning system of the vehicle. The heat exchange medium here can also be called a working medium.

[0125] According to the utility model, the adapter assembly 140 is arranged on the hydraulic pump 100 and the motor 110. The adapter assembly 140 is used to detect the oil temperature of the hydraulic pump 100. The motor controller 150150 may also include a temperature and pressure communication socket 158e. The temperature and pressure communication socket 158e is connected to the electric control housing 151. The control circuit board 158 is fixedly connected to the temperature and pressure communication socket 158e. The second component 142 of the adapter assembly 140 includes a communication plug 142c. The communication plug 142c is plugged with the temperature and pressure communication socket 158e. The temperature and pressure communication socket 158e is suitable for being electrically connected to the control device of the vehicle. The adapter assembly 140 can detect the oil temperature of the hydraulic pump 100 and send it to the control circuit board 158. The control circuit board 158 transmits the oil temperature to the control device of the vehicle via the temperature and pressure communication socket 158e. The control circuit board 158 can also receive control instructions from the control device, and control the operating states of the first sensor 131 , the second sensor 132 , and the motor 110 according to the control instructions, thereby indirectly controlling the operating state of the hydraulic pump 100 .

[0126] According to the utility model, the adapter assembly 140 is arranged between the hydraulic pump 100 and the motor 110. The first hydraulic pump 100 is a bidirectional hydraulic pump 100, and includes a first opening and a second opening suitable for circulating oil. One end of the adapter assembly 140 is electrically connected to the first sensor 131 and the second sensor 132. The other end of the adapter assembly 140 is used to be electrically connected to the motor controller 150150 to send the detected oil temperature to the motor controller 150150. By connecting the first sensor 131 and the second sensor 132 through an adapter assembly 140, the adapter assembly 140 can transmit the oil temperature detected by the first sensor 131 and the second sensor 132 to the motor controller 150150. In this way, the space occupied by the adapter assembly 140 can be reduced, the circuit structure can be simplified, and it is helpful to reduce the difficulty of sealing, save costs and improve the compactness of the pump structure of the motor 110.

[0127] The embodiment of the first embodiment of the utility model also provides a hydraulic energy supply device. The hydraulic energy supply device may include two motor 110 pump assemblies as described above. The two motor 110 pump assemblies are coaxial and arranged opposite to each other in the first direction D1. The axial direction of the motor 110 pump assembly is parallel to the first direction D1. The housings 111 of the two motor 110 pump assemblies are connected in the first direction D1.

[0128] The hydraulic energy supply device according to the embodiment of the utility model is easy to install and maintain and can also reduce costs by applying the above-mentioned motor 110 pump assembly.

[0129] In addition, the hydraulic energy supply device may further include a motor controller 150150. The motor controller 150150 is disposed outside the housing 111 and connected to the housing 111. The second end of the second component 142 passes through the housing 111 and is connected to the motor controller 150150. In this way, the first sensor 131 and the second sensor 132 can be connected to the motor controller 150 through the second component 142 of the adapter component 140. The motor controller 150150 is used to receive detection data of the first sensor 131 and the second sensor 132. The detection data here includes but is not limited to temperature.

[0130] Optionally, the cooling channel 111a is located at a portion of the housing 111 facing or close to the motor controller 150. In this way, the heat generating components of the motor controller 150 can be cooled while cooling the motor 110. The heat generating components here include but are not limited to power devices 152 such as IGBTs.

[0131] In addition, the motor controller 150150 may also include a control circuit board 158. The second end of the second component 142 passes through the housing 111 and is plugged into the control circuit board 158. Here, the second component 142 is connected to the control circuit board 158 of the motor controller 150150 by plugging, which is convenient for disassembly, assembly and maintenance.

[0132] The first embodiment of the utility model further provides a chassis system. The chassis system may include a shock absorber and the above-mentioned hydraulic energy supply device. The hydraulic energy supply device is fluidically connected to the shock absorber to supply hydraulic energy to the shock absorber.

[0133] According to the chassis system of the embodiment of the utility model, by applying the above-mentioned hydraulic energy supply device, the installation and maintenance of the chassis system are facilitated and the cost is reduced.

[0134] The first embodiment of the utility model further provides a vehicle, which may include the above-mentioned chassis system.

[0135] The vehicle according to the embodiment of the utility model, by applying the above-mentioned chassis system, is beneficial to improving assembly efficiency, facilitating maintenance, and reducing costs.

[0136] Second embodiment

[0137] See also Figures 1 to 9The second embodiment of the utility model provides a motor 110 assembly. The motor 110 assembly may include a motor 110 and a motor controller 150150. The motor 110 may include a housing 111. The housing body 112 of the housing 111 is recessed to form a cooling channel 111a suitable for circulating a coolant. The cooling channel 111a is used to circulate a heat exchange medium. The heat generated by the motor controller 150 can be exchanged by the heat exchange medium, thereby achieving the effect of dissipating heat and cooling the motor controller 150. The heat exchange medium of the cooling channel 111a can perform heat exchange at other parts of the heat exchange circuit to achieve cooling of the heat exchange medium. The motor 110 assembly may also include a flow channel plate 113 and a boss 113a. The flow channel plate 113 is covered on the cooling channel 111a. The boss 113a is protrudingly arranged on the first side of the flow channel plate 113 away from the cooling channel 111a. The motor controller 150150 is connected to the motor 110. The motor controller 150150 includes a power device 152. The power device 152 is disposed on a surface of the boss 113a that is away from the cooling channel 111a. The power device 152 is connected to the boss 113a to conduct heat through the boss 113a.

[0138] According to the motor 110 assembly of the embodiment of the utility model, by setting a boss 113a on the flow channel plate 113 for connecting the power device 152, the distance between the power device 152 and the remaining surfaces of the flow channel plate 113 except the boss 113a can be increased, thereby ensuring that the cooling flow channel 111a can reliably dissipate heat for the power device 152 while increasing the safety distance between the power device 152 and the housing 111 of the motor 110, and thus there is no need to strengthen the insulation treatment on the remaining surfaces of the flow channel plate 113 except the boss 113a, thereby reducing the production cost of insulation treatment and the like.

[0139] See also Figures 2 to 6 For example, the boss 113a and the flow channel plate 113 are an integral part. A guide recess 113b is formed on the second side of the flow channel plate 113 corresponding to the first side. The guide recess 113b corresponds to the boss 113a. By providing the boss 113a and the flow channel plate 113 as an integral part, the number of parts can be reduced and disassembly and assembly are facilitated. By providing the guide recess 113b, it is helpful to ensure that the thickness of the boss 113a is consistent with the thickness of the flow channel plate 113, thereby improving the uniformity of heat dissipation at the flow channel plate 113 and the boss 113a.

[0140] In other examples, the flow channel plate 113 may be a part of the housing 111 , that is, the flow channel plate 113 and the housing body 112 are fixed together to form a part of the housing 111 .

[0141] In other examples, the flow channel plate 113 may be a part of a power component including the power device 152. For example, the flow channel plate 113 is configured as at least a part of a housing of the power component.

[0142] See also Figure 2 , Figure 4 and Figure 6 For example, the motor 110 assembly may include three bosses 113a and three groups of power devices 152. Each group of power devices 152 forms a phase bridge arm. Each group of power devices 152 is respectively arranged on a boss 113a. That is, the three groups of power devices 152 are arranged on the three bosses 113a in a one-to-one correspondence. Thus, the three bosses 113a can be used to dissipate heat for the three groups of power devices 152 respectively.

[0143] In other examples, the number of the bosses 113 a may not be limited to three. The number of groups of the power devices 152 is also not limited to three.

[0144] See also Figure 2 and Figure 3 For example, the power device 152 may include a device body 152a and a pin 152b. The device body 152a is connected to the boss 113a. The pin 152b is spaced apart from the boss 113a. The device body 152a here is the main heat generating part of the power device 152. By connecting the device body 152a of the power device 152 with the boss 113a, it can be effectively ensured that the flow channel plate 113 can reliably exchange heat with the device body 152a of the power device 152. The pin 152b is a conductive connection part connecting the power device 152 with other components and circuit structures. By spaced apart from the boss 113a, it can be effectively ensured that the pin 152b is insulated from the boss 113a, thereby preventing the pin 152b from short-circuiting with the boss 113a.

[0145] Optionally, in a plane perpendicular to the third direction D3, the orthographic projection of the boss 113a is completely located inside the orthographic projection of the device body 152a, so as to further ensure a safer distance between the boss 113a and the pin 152b.

[0146] See also Figures 1 to 6 In addition, the housing 111 may also include a housing body 112. A mounting groove 112a is provided in the portion of the housing body 112 facing the motor controller 150150. The housing body 112 may include a guide rib 112b. The guide rib 112b is disposed in the mounting groove 112a to define a cooling channel 111a in the mounting groove 112a. The channel plate 113 is covered at the notch of the mounting groove 112a. In short, the inner surface of the mounting groove 112a, the guide rib 112b and the channel plate 113 enclose a cooling channel 111a with a closed cross-section. Here, by dividing the housing 111 into the housing body 112 and the channel plate 113, it is convenient to manufacture the housing body 112 and the channel plate 113 separately, so as to realize the separate processing of different parts of the cooling channel 111a, thereby reducing the processing difficulty and also helping to improve the processing accuracy.

[0147] Optionally, when the flow channel plate 113 is installed in the installation groove 112a, the flow channel plate 113 and the guide rib 112b may be sealed and connected, so that the coolant can flow completely along the cooling flow channel 111a, which is beneficial to the controllability of the cooling effect.

[0148] Schematically, the cooling channel 111a is arranged in a circuitous shape. By setting the cooling channel 111a in a circuitous or meandering shape, it is helpful to increase the residence time of the heat exchange medium in the cooling channel 111a, so as to more fully exchange heat with the motor controller 150150 to achieve a better heat dissipation effect. The circuitous shape here is not limited to the form shown in the figure, and can also be any other form that can increase the extension length of the cooling channel 111a in an area of ​​the same size.

[0149] For example, the extension track of the guide rib 112b is in a tortuous shape, thereby defining a tortuously arranged flow channel groove. When the flow channel plate 113 is installed in the installation groove 112a, the tortuous cooling flow channel 111a can be formed in the housing 111. In this way, the length of the cooling flow channel 111a can be increased, thereby extending the circulation time of the coolant in the housing 111, which is conducive to sufficient heat exchange between the coolant and the housing 111, thereby improving the cooling effect.

[0150] See also Figure 5 and Figure 6 For example, the bottom wall of the mounting groove 112a is provided with a guide boss 113a at a position corresponding to the boss 113a. By providing the guide boss 113a, the coolant can be guided toward the boss 113a at the boss 113a, so that the coolant can fully contact the inner surface of the guide boss 113a, thereby ensuring that the guide boss 113a can effectively cool the power device 152.

[0151] Optionally, a guide rib 112c is provided at a portion of the guide rib 112b corresponding to the boss 113a. The guide rib 112c can better fit the surface of the flow channel plate 113 at the boss 113a, thereby ensuring the sealing between the guide rib 112c and the flow channel plate 113.

[0152] Continue reading Figure 5 and Figure 6 For example, the flow channel plate 113 may include an auxiliary heat sink 113c. The auxiliary heat sink 113c is extended along the third direction D3 of the flow channel plate 113. The auxiliary heat sink 113c is located in the cooling flow channel 111a. By providing the auxiliary heat sink 113c on the flow channel plate 113, the contact area between the flow channel plate 113 and the heat exchange medium in the flow channel plate 113 can be increased, thereby further improving the heat exchange efficiency.

[0153] Furthermore, the flow channel plate 113 may include a plurality of auxiliary heat sinks 113c. Each auxiliary heat sink 113c is arranged at intervals along an arrangement path adapted to the cooling flow channel 111a. This can further increase the contact area between the flow channel plate 113 and the coolant and improve the heat exchange efficiency.

[0154] Specifically, the auxiliary heat sink 113c can be configured as a heat sink pin. The heat sink pin is extended along the groove depth direction of the mounting groove 112a. The flow channel plate 113 may include a plurality of heat sink pins. Each heat sink pin is arranged at intervals along an arrangement path adapted to the cooling flow channel 111a. That is, when the flow channel plate 113 is covered at the notch of the mounting groove 112a, the heat sink pin is located in the cooling flow channel 111a.

[0155] Optionally, the heat dissipation pins are spaced apart from the guide ribs 112 b.

[0156] For example, a support and positioning column 113d is also protrudingly provided on the first side of the flow channel plate 113. The support and positioning column 113d is provided with a threaded hole. The support and positioning column 113d is used to be connected to the driving circuit board 159 through fasteners such as screws. The support and positioning column 113d also plays a role of supporting and limiting between the flow channel plate 113 and the driving circuit board 159.

[0157] See also Figures 1 to 6 In one example, the motor 110 assembly may include two motors 110. The two motors 110 are coaxial and arranged opposite to each other. The housings 111 of the two motors 110 are connected. This can improve the output power of the motor 110 assembly while improving the integration of the motor 110 assembly.

[0158] In another example, the motor 110 assembly may include a housing 111 and two motor bodies 114. The motor bodies 114114 are disposed in the housing 111. The two motor bodies 114114 are coaxial and arranged opposite to each other.

[0159] See also Figures 2 to 6For example, the motor controller 150150 may include a capacitor 153. The two motors 110 may include two housings 111, or may share one housing 111. Taking the example that the two motors 110 each include a housing 111, a receiving groove 112p is formed at the connection of the two housings 111. The receiving groove 112p is located between the two motor bodies 114. The notch of the receiving groove 112p faces the motor controller 150150. The receiving groove 112p is at least used to accommodate the capacitor 153. By accommodating the capacitor 153 in the receiving groove 112p, the occupation of the external space of the motor 110 by the capacitor 153 can be reduced, the space utilization rate of the motor 110 can be improved, and the compactness of the structure of the motor 110 assembly can be improved. Furthermore, the capacitor 153 can be connected to the power device 152 of the cooling channel 111a corresponding to the two motors 110. This helps to integrate the motor controllers 150150 required to be connected to the two motors 110, so that the two power devices 152 share one capacitor 153 or the capacitor 153 required to be connected to the two power devices 152 is placed in the receiving groove 112p, thereby improving the integration of the motor controllers 150150.

[0160] Optionally, the receiving slot 112p can also be used to receive electrical components or devices other than the capacitor 153. For example, the receiving slot 112p can also be used to receive the three-phase components of the motor 110.

[0161] Furthermore, the ends of the housing bodies 112 of the two housings 111 facing each other are recessed to form a partial groove 112o. The partial groove 112o of the two housings 111 forms a receiving groove 112p after the two housings 111 are assembled.

[0162] See also Figures 2 to 6 , further, the housing 111 may include a heat dissipation support portion 112h located in the receiving groove 112p. The capacitor 153 is arranged on the upper part of the heat dissipation support portion 112h. The motor 110 component may also include a heat dissipation elastic glue 164. The heat dissipation elastic glue 164 is connected between the heat dissipation support portion 112h and the capacitor 153 to conduct heat between the heat dissipation support portion 112h and the capacitor 153. On the one hand, the heat dissipation support portion 112h can be used to support the capacitor 153. On the other hand, the heat dissipation elastic glue 164 can be used to increase the heat exchange area between the capacitor 153 and the heat dissipation support portion 112h to improve the heat exchange efficiency. Since the heat dissipation support portion 112h is a part of the housing 111, the housing 111 can be used to exchange heat with the heat exchange medium in the cooling channel 111a and the capacitor 153, respectively, so as to achieve the purpose of heat dissipation of the capacitor 153.

[0163] Optionally, the electric control housing 151 can be fastened to the housings 111 of the two motors 110 by fasteners such as bolts. It can be understood that in order to facilitate the positioning and assembly of the electric control housing 151 and the housings 111 of the two motors 110, positioning structures can be respectively provided at corresponding positions between the electric control housing 151 and the housings 111. The positioning structure here can be divided into two parts, one part of the positioning structure is provided in the electric control housing 151, and the other part of the positioning structure is provided in the housing 111. One part of the two parts of the positioning structure can be configured as a positioning hole, and the other part can be configured as a positioning column adapted to the positioning hole.

[0164] In some embodiments, the housings 111 of the two motors 110 can be welded together by friction welding. During the welding process, the motor 110 housing positioning hole on one housing 111 and the motor 110 housing positioning column on the other housing 111 can be used to limit the two housings 111 to each other. In this way, the end faces of the two housings 111 can be closely fitted, so that the connection structure of the two housings 111 is more secure after friction welding.

[0165] It is understandable that if the two housings 111 are connected to each other by welding, the welding method is not limited to friction welding. For example, other welding methods that can ensure the stability of the connection structure of the two housings 111 and the sealing of the connection can be selected.

[0166] See also Figures 1 to 6 In one example, the two housings 111 are manufactured separately and then assembled into an integrated dual-motor 110 housing. The cooling channels 111a located in the two housings 111 can be selected to be connected in parallel in the integrated dual-motor 110 housing. That is, the cooling channels 111a located in the two housings 111 are spaced apart inside the integrated dual-motor 110 housing. In other words, the two cooling channels 111a are respectively connected to the corresponding external heat exchange devices through pipelines on the outside of the integrated dual-motor 110 housing. For example, the two cooling channels 111a are each connected to the heat exchange circuit of the air conditioner to share the heat exchange medium with the air conditioner. The scheme of the two cooling channels 111a being connected in parallel can be applied to an embodiment in which the two housings 111 are first manufactured separately and then assembled together and the two share a receiving groove 112p. The receiving groove 112p here will affect the arrangement of the two cooling channels 111a.

[0167] Continue reading Figures 1 to 6, further, the cooling channel 111a has a first liquid through hole 112f and a second liquid through hole 112g. The first liquid through hole 112f is for the heat exchange medium to flow into the cooling channel 111a, and the second liquid through hole 112g is for the heat exchange medium to flow out of the cooling channel 111a. The first liquid through hole 112f and the second liquid through hole 112g of one of the two housings 111 are connected to the heat exchange circuit of the air conditioner through a set of pipes. The first liquid through hole 112f and the second liquid through hole 112g of the other housing 111 of the two housings 111 are connected to the heat exchange circuit of the air conditioner through another set of pipes.

[0168] Furthermore, the end of the shell body 112 for mounting the hydraulic pump 100 is provided with a first liquid hole 112f and a second liquid hole 112g. The first liquid hole 112f and the second liquid hole 112g are arranged at intervals along the first direction D1. The motor 110 may also include a first liquid joint 121 and a second liquid joint 122. The first liquid joint 121 is mounted to the first liquid hole 112f and is connected to the cooling channel 111a and the outside. The second liquid joint 122 is mounted to the second liquid hole 112g and is connected to the cooling channel 111a and the outside. The first liquid joint 121 and the second liquid joint 122 are used to connect pipelines located outside the motor 110.

[0169] In other embodiments not shown, the cooling channels 111 a of the two motors 110 are respectively located on both sides of the accommodating groove 112 p , and the two cooling channels 111 a are connected in series inside the integrated dual motor 110 shell.

[0170] The second embodiment of the present invention further provides a hydraulic energy supply device for an active suspension, wherein the hydraulic energy supply device may include the motor 110 assembly described above.

[0171] According to the hydraulic energy supply device of the embodiment of the utility model, the cost of the hydraulic energy supply device can be reduced by applying the above-mentioned motor 110 assembly.

[0172] The second embodiment of the present utility model further provides a hydraulic energy supply device.

[0173] The hydraulic power supply device may include the above-mentioned motor 110 assembly. The hydraulic power supply device may include a first hydraulic pump 100 and a second hydraulic pump 100. The motor 110 assembly may include a first motor 110 and a second motor 110. The first motor 110 is connected to the first hydraulic pump 100 and is suitable for driving the first hydraulic pump 100. The second motor 110 is connected to the second hydraulic pump 100 and is suitable for driving the second hydraulic pump 100.

[0174] According to the hydraulic energy supply device of the embodiment of the utility model, the cost of the hydraulic energy supply device can be reduced by applying the above-mentioned motor 110 assembly.

[0175] For example, the housing 111 includes a first housing 111 and a second housing 111. Here, the combination of the first housing 111 and the second housing 111 is referred to as the housing 111. The first housing 111 and the second housing 111 are connected. The first hydraulic pump 100 is disposed at an end of the first housing 111 away from the second housing 111. The second hydraulic pump 100 is disposed at an end of the second housing 111 away from the first housing 111.

[0176] See also Figures 1 to 9 For example, the motor 110 may be a three-phase motor 110. The three-phase motor 110 may include a motor body 114. The motor body 114 is located inside the housing 111. The housing 111 is provided with a wire passing hole 112k. The motor 110 assembly may include a three-phase lead wire 114a. The three-phase lead wire 114a is electrically connected to the stator winding in the motor 110 or is a part of the stator winding. For example, the stator winding may include a winding body and a three-phase lead wire 114a. The three-phase lead wire 114a may include a root end and a tip end. The root end and the tip end here may be understood as the two ends of the three-phase lead wire 114a along its own length direction. The root end of the three-phase lead wire 114a is installed on the stator core of the motor 110. The three-phase lead wire 114a is passed through the wire passing hole 112k and is sealed and connected to the wire passing hole 112k through a three-phase wire seal 114b. The motor 110 assembly may also include a three-phase component of the motor 110. The three-phase component of the motor 110 here may be referred to as a three-phase copper busbar 119. The three-phase copper busbar 119 includes three first electrical terminals 119a, three second electrical terminals 119c, and an insulating seat 119d. The first electrical terminal 119a and the second electrical terminal 119c are each at least partially covered on the insulating seat 119d to support and fix the first electrical terminal 119a and the second electrical terminal 119c through the insulating seat 119d. The three first electrical terminals 119a are each connected to the three second electrical terminals 119c in a one-to-one correspondence. Or the three first electrical terminals 119a are each constructed as one body in a one-to-one correspondence with the three second electrical terminals 119c. The first electrical terminal 119a is connected to the three-phase lead wire 114a. The end of the first electrical terminal 119a is protrudingly formed with a pier 119b. The pier 119b is connected to the conductor of the three-phase lead wire 114a. The second electrical terminal 119c is used to be electrically connected to the motor controller 150150. The motor controller 150150 converts the electric energy of the power source and provides it to the motor 110 respectively, so as to control the running state of the motor 110.

[0177] Optionally, the cross-sectional shape of the three-phase lead wire 114a may be a square, which is beneficial to increase the contact area between the three-phase lead wire 114a and the first electrical terminal 119a.

[0178] After the motor body 114 is assembled to the inside of the housing 111, the inner conductor of the three-phase lead wire 114a is pressed against the pier 119b and is conductively connected. The outer surface of the pier 119b is a circular arc surface and other curved surfaces, which can guide the three-phase lead wire 114a through the circular arc surface during the assembly of the three-phase lead wire 114a, which is conducive to the three-phase lead wire 114a moving along the circular arc surface to the more protruding part of the pier 119b and abutting against it. When the inner conductor of the three-phase lead wire 114a abuts against the more protruding part of the pier 119b, the abutting force between the first electrical terminal 119a and the three-phase lead wire 114a is greater, so that the three-phase copper bus 119 and the three-phase lead wire 114a are reliably conductively connected. Since the inner conductor of the three-phase lead wire 114a is in contact with the arc surface of the pier 119b and the contact area is small, this three-phase copper busbar 119 can be suitable for the motor 110 with a smaller rated current.

[0179] In other examples, the structure of the first electrical terminal 119a may also be other structures different from the first electrical terminal 119a having the package 119b described above, for example, connected by fasteners.

[0180] See also Figure 3 Optionally, the second electrical terminal 119c can be plugged and installed with the electrical connection part of the motor controller 150150. The first electrical terminal 119a can be connected to the three-phase lead wire 114a by one of the connection modes such as plugging, welding and connection by fasteners.

[0181] Optionally, the three-phase copper busbars 119 may be arranged in a vertical shape.

[0182] See also Figures 2 to 6 Furthermore, a receiving groove 112p is formed between the two motors 110. Part of the three-phase lead wire 114a and the three-phase copper busbar 119 are located in the receiving groove 112p. Electrical components or devices such as the capacitor 153 of the motor controller 150150 can also be accommodated in the receiving groove 112p. By providing a receiving groove 112p between the two motors 110 to accommodate part of the three-phase lead wire 114a, the three-phase copper busbar 119 and the electrical components or devices such as the capacitor 153 of the motor controller 150150, the space utilization rate of the two motors 110 in the first direction D1 can be improved, which is also helpful to improve the integration of the motor 110 components, while reducing the space occupied in the third direction D3, and improving the compactness of the structure in the third direction D3.

[0183] The second embodiment of the present invention further provides a chassis system, which may include a shock absorber and the above-mentioned hydraulic power supply device, wherein the hydraulic power supply device is fluidically connected to the shock absorber.

[0184] The chassis system according to the embodiment of the utility model can reduce production costs by applying the above-mentioned hydraulic energy supply device.

[0185] The second embodiment of the present invention further provides a vehicle, which may include the motor 110 assembly, or the hydraulic power supply device, or the chassis system.

[0186] The vehicle according to the embodiment of the utility model can reduce production costs by applying the above-mentioned motor 110 assembly, or the above-mentioned hydraulic power supply device, or the above-mentioned chassis system.

[0187] For example, the motor 110 assembly may include a first motor 110, a second motor 110, a first flow channel, and a second flow channel. The first flow channel is provided at the first motor 110. The second flow channel is provided at the second motor 110. The vehicle may further include an air conditioner. The air conditioner fluid is connected to the first flow channel and / or the second flow channel.

[0188] The first embodiment and the second embodiment of the utility model can be implemented separately or in combination. It is understood that those skilled in the art can obtain other modified embodiments by modifying the first embodiment, the second embodiment and their combination, and these modified embodiments can be used to solve corresponding technical problems and obtain expected technical effects.

[0189] The following is combined with Figures 1 to 9 A hydraulic energy supply device according to an embodiment of the utility model is described in detail.

[0190] The hydraulic energy supply device of the utility model includes two motor 110 pump assemblies, a first water pipe assembly 171, a second water pipe assembly 172 and a motor 110 control. The sides of the motor 110 pump assembly are respectively a motor end cover 116 and a cantilever 117 for connecting to the vehicle chassis. The cantilever 117 and the end cover are integrally formed. The motor controller 150 has a signal connector 154 for communication connection with the whole vehicle and a busbar electrical terminal 155 for connecting to the power supply of the motor 110. The first water pipe assembly 171 can simultaneously connect the first liquid holes 112f of the two motor 110 pump assemblies. The second water pipe assembly 172 can simultaneously connect the second liquid holes 112g of the two motor 110 pump assemblies. The first water pipe assembly 171 and the second water pipe assembly 172 each have a three-way water pipe 173, and the two three-way water pipes 173 are respectively used to connect the outlet pipe and the inlet pipe of the cooling system of the whole vehicle.

[0191] During the process of coolant flowing through the cooling channel 111a, the coolant enters the cooling channel 111a from the first liquid hole 112f and passes through the guide rib 112b to make the coolant detour to the motor body 114 to dissipate heat to the maximum extent, and then flows out from the second liquid hole 112g. The coolant can also flow into the second liquid hole 112g and out of the first liquid hole 112f in the above manner. There are heat dissipation pins and three bosses 113a on the flow channel plate 113, and the heat dissipation pins and the guide ribs 112b in the cooling channel 111a are staggered. Because the material thickness of these three bosses 113a is relatively thick and far away from the coolant, in order to reduce the material thickness here and make the coolant closer to the IGBT device, the material below the boss 113a is reduced and made into a wavy pit. The wavy pit is made to facilitate the smooth flow of the coolant. At the same time, in order to allow the coolant to pass through the pits of the flow channel plate 113, three wavy bosses 113a are made at the corresponding positions of the pits of the cooling flow channel 111a, and the corresponding positions of the pits of the guide rib 112b are also made into wavy protrusions, so that the cooling flow channel 111a can not only dissipate heat for the motor 110, but also better dissipate heat for the electronically controlled power device 152. The reason why the boss 113a is set here is that the distance between the pin 152b of the IGBT and the flow channel plate 113 is relatively close, and there is a risk of insufficient high-voltage conductive safety spacing (the cross-sectional view will further explain it). After the boss 113a is made, the electrical safety distance between the IGBT pin 152b and the flow channel plate 113 can be increased. The housing 111 is also provided with a second positioning hole 112j for assembling the second positioning pin 161, which is convenient for assembly and limiting with the electric control housing 151; the two first positioning holes 112i on the housing 111 can be positioned and connected with another housing 111 through the motor positioning pins 115115, which is used for limiting the position of the two motor 110 pump assemblies during assembly. The housing 111 also has a first connection hole 112e, a wire hole 112k, a heat dissipation support part 112h for supporting the capacitor 153 and dissipating heat for the capacitor 153, and a rotary transformer through hole 112m.

[0192] The assembly method of the hydraulic energy supply device provided in the embodiment of the utility model may include:

[0193] First, install the first water pipe assembly 171 and the second water pipe assembly 172 into the first liquid-passing joint 121 and the second liquid-passing joint 122 corresponding to the housing 111, install the second positioning pin 161 into the third positioning hole 151a of the electric control housing 151 and the second positioning hole 112j of the housing 111 to achieve the limiting of the housing 111 and the electric control housing 151, and install the motor positioning pin 115 into the first positioning hole 112i of the two housings 111 to achieve the limiting of the two housings 111. Then install the motor body 114 with the three-phase line seal 114b installed into the housing 111. After the first sensor 131 and the second sensor 132 with the temperature and pressure sensor sealing ring 133 are installed into the second connection hole 101a and the third connection hole 101b of the hydraulic pump 100, the adapter component 140 is passed through the first connection hole 112e, and the second component 142 is sleeved with a sealing sleeve 142d and stuck at the first connection hole 112e so that the second component 142 is not damaged by friction. At the same time, the sealing sleeve 142d can prevent the heat of the motor 110 from flowing to the motor controller 150 and generating condensation. Then, the communication plug 142a of the second component 142 is plugged into the communication socket 141b of the first component 141, and the communication plug 142c of the second component 142 is plugged into the temperature and pressure communication socket 158e on the control circuit board 158 of the motor controller 150. Finally, the motor end cover 116 with the cantilever 117 is assembled and connected to the pump housing 101 of the hydraulic pump 100.

[0194] Then, the three-phase copper busbar 119 is installed in the receiving groove 112p, and the pier 119b of the first electrical terminal 119a of the three-phase copper busbar 119 is connected to the three-phase lead-out line 114a. After the resolver fixing seat 118a and the resolver body 118c of the resolver assembly 118 are respectively assembled to the housing 111 and connected, the resolver communication line 142b bundle 118d is connected to the resolver body 118c, and the resolver communication line 142b bundle 118d is fixed to the resolver body 118c to prevent the resolver communication line 142b bundle 118d from loosening. At the same time, there are shielding and adhesive layers on the resolver communication line 142b bundle 118d, which can adhere the resolver communication line 142b bundle 118d and the housing 111 together to prevent the resolver communication line 142b bundle 118d from loosening and being worn and damaged, and to play a role in shielding and preventing signal interference.

[0195] After the motor body 114 of the motor 110 is assembled, its three-phase lead wire 114a and the pier bag 119b are interference fit. Since both sides of the pier bag 119b are arcs, it is convenient for the three-phase lead wire 114a to be inserted and passed during assembly. Since the three-phase lead wire 114a is a square structure, it is convenient to increase the contact area between the three-phase lead wire 114a and the pier bag 119b, so as to facilitate the flow of a larger current. The three-phase copper bus 119 and the AC connector 159c of the drive circuit board 159 are vertically connected and conductive. A three-phase wire seal 114b is provided on the three-phase lead wire 114a to prevent the coolant of the motor 110 from overflowing the motor 110 housing. A DC connector 159b is provided on the side of the drive circuit board 159 away from the three-phase copper bus 119. The DC connector 159b is connected to the DC bus electrical terminal 155. The DC bus electrical terminal 155 is used to connect to an external DC power supply.

[0196] Above the boss 113a of the flow channel plate 113 is a power device 152 such as an IGBT. The reason why the flow channel plate 113 is provided with the boss 113a is that the voltage at the pin 152b of the power device 152 such as the IGBT is high voltage, and a certain electrical safety distance needs to be maintained between the pin 152b and the surface of the flow channel plate 113 outside the boss 113a. In order to meet this electrical safety distance and the pin 152b of the power device 152 does not need to be additionally insulated to increase the cost, the boss 113a is provided. After the boss 113a is added to the flow channel plate 113, the thickness of the corresponding part of the boss 113a is thicker and the power device 152 is far away from the coolant in the cooling channel 111a, so a guide recess 113b structure is made under the boss 113a to make the thickness of the flow channel plate 113 uniform. At the same time, in order to allow the coolant to flow to the guide recess 113b, there is a guide boss 113a on the shell body 112. This can make the coolant closer to the power device 152, so that the heat dissipation effect is better. In addition, the flow channel plate 113 has many heat dissipation pins, which can be immersed in the coolant in the cooling channel 111a, so that the entire flow channel plate 113 can be well cooled, thereby better cooling the power device 152. Since there is also oil in the inner cavity of the motor 110 below the cooling channel 111a, the coolant in the cooling channel 111a can dissipate heat for the oil in the inner cavity of the motor 110 while dissipating heat for the power device 152, thereby also improving the heat dissipation effect of the motor 110. Above the power device 152 are the drive circuit board 159, the shielding plate 157, the control circuit board 158, the signal transfer circuit board 163 and the electric control housing 151. The second signal plug 159d on the drive circuit board 159 and the second signal socket 158c of the control circuit board 158 are connected and conductive. The first signal plug 158a on the control circuit board 158 is connected to the first signal socket 163a on the signal transfer circuit board 163, and then the signal transfer circuit board 163 is connected to the whole vehicle through the signal connector 154, and the signal connector 154 can be fixed to the signal transfer circuit board 163. The drive circuit board 159, the control circuit board 158, and the signal transfer circuit board 163 are all assembled and connected vertically through the connector, which is conducive to automated production. There is a capacitor 153 below the control circuit board 158. Because the capacitor 153 is relatively large and heavy, it is welded on the control circuit board 158, so that the load-bearing capacity of the control circuit board 158 is relatively large, so a heat dissipation support part 112h is provided on the housing 111, and a heat dissipation elastic glue 164 is installed on the heat dissipation support part 112h and contacts with the capacitor 153, so that the capacitor 153 can be supported by the heat dissipation support part 112h and the heat dissipation elastic glue 164 to reduce the load-bearing capacity of the control circuit board 158, and the capacitor 153 also obtains a certain heat dissipation effect. The electric control housing 151 also has a breathable valve 156 for preventing condensation and balancing the pressure difference by dissipating heat.

[0197] It can also be seen from the figure that the adapter component 140 is fixed to the first connection hole 112e of the housing 111 through the sealing sleeve 142d. The cross-sectional shape of the sealing sleeve 142d is an "I" shape or close to an "I" shape or other shapes to prevent the sealing sleeve 142d from falling off due to vibration in the third direction D3. One end of the second component 142 of the adapter component 140 is connected to the temperature and pressure communication socket 158e on the control circuit board 158 through the communication plug 142c, and the other end of the second component 142 is plugged into the communication socket 141b of the first component 141 through the communication plug 142a. The communication plug 142c of the second component 142 and the communication plug 142a are connected through the communication line 142b. The sensor adapter board 141a of the first component 141 is connected to the first sensor 131 and the second sensor 132. In this way, the first sensor 131 and the second sensor 132 are connected to the control circuit board 158 via the adapter component 140, which can save space and sealing and signal conversion costs, and can prevent the hot air from the motor 110 from flowing to the motor controller 150, thereby preventing the motor controller 150 from generating condensation due to the intrusion of hot air.

[0198] During the assembly process, first install the third positioning pin 162 in the circuit board positioning hole 112n of the housing 111. Then install the driving circuit board 159, the shielding plate 157 and the control circuit board 158 in sequence, so that the sixth positioning hole 159a, the fourth positioning hole 157a and the fifth positioning hole 158d pass through the third positioning pin 162 in sequence to ensure that the assembly positions of the driving circuit board 159 and the control circuit board 158 are consistent, so that the driving circuit board 159 and the control circuit board 158 are vertically installed and connected through the connector. Then, the adapter assembly 140 and the resolver communication line 142b bundle 118d are respectively connected to the temperature and pressure communication socket 158e and the resolver communication socket 158f of the control circuit board 158. The signal connector 154 is fixed to the signal transfer circuit board 163. Since the signal connector 154 is to be assembled horizontally with the electric control housing 151, the signal transfer circuit board 163 is installed in the electric control housing 151 and then assembled and connected with the control circuit board 158. To ensure the assembly accuracy of the electric control housing 151 and the motor 110, so that the signal transfer circuit board 163 and the control circuit board 158 are accurately connected. The electric control housing 151 has an electric control box positioning hole (not shown) connected to the electric control box positioning pin (not shown). Then install the busbar electrical terminal 155, so that the copper bar of the busbar electrical terminal 155 is inserted into the AC connector 159c on the drive circuit board 159. This connection method is the same as the three-phase copper bar 119 connection mentioned above, similar to the plug and socket of household appliances, and the assembly connection is simple and easy to operate. At the same time, the three-phase copper bar 119 is placed upright to facilitate heat dissipation. Finally, install the first water pipe assembly 171 and the second water pipe assembly 172. Thus, the assembly of the hydraulic power supply device is completed.

[0199] In summary, the hydraulic energy supply device of the utility model can also be called an integrated dual-motor 110 MPU. The utility model sets a wavy cooling channel 111a structure in the casing 111 to form a cooling channel 111a, which can make the coolant closer to the power device 152 such as IGBT, so as to be more conducive to heat dissipation. In this way, the power of the motor 110 with the same volume can be increased. At the same time, the boss 113a can increase the safety spacing between the power device 152 and the casing 111, without strengthening the insulation treatment, reducing the insulation treatment cost. The three-phase lead wire 114a adopts a square cross-section structure to contact the three-phase copper bus 119, which can increase the contact area between the three-phase lead wire 114a and the three-phase copper bus 119, thereby improving the overcurrent capacity of the connection part between the three-phase lead wire 114a and the three-phase copper bus 119. By setting the adapter assembly 140, the first sensor 131, the second sensor 132 are connected to the motor controller 150, the circuit between the first sensor 131, the second sensor 132 and the motor controller 150 can be saved, so as to simplify the circuit structure, and it is convenient for disassembly and maintenance. At the same time, the adapter assembly 140 is separated from the housing 111 by a sealing sheath 142d such as a rubber sleeve, which can prevent the adapter assembly 140 from rubbing on the one hand, and can prevent the hot air of the motor 110 from flowing into the motor controller 150 and producing condensation on the other hand. The DC bus, the three-phase lead wire 114a, the drive circuit board 159, the control circuit board 158 and the signal transfer circuit board 163 are all connected by the connector up and down, which can save assembly space and is conducive to automated production. At the same time, the three-phase copper bus 119 arranged in a vertical shape can improve the heat dissipation effect. The capacitor 153 is connected to the heat dissipation support part 112h by a soft material such as a heat dissipation elastic glue 164 that is conducive to heat dissipation, and has both heat dissipation and support. This can prevent the capacitor 153 from falling off the control circuit board 158 of the motor controller 150 when vibrating.
