[0021] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0022] Reference below Figure 1-Figure 5 A driving module 10 according to an embodiment of the present invention is described. The driving module 10 may be applied to a powertrain 100 , and the powertrain 100 may be applied to a vehicle 1000 .

[0023] Combination Figure 1-Figure 5As shown, the driving module 10 according to the present invention is suitable for being arranged on a powertrain 100 including an actuator 20, the first end of the driving module 10 is suitable for being electrically connected to an actuator control unit 40 on the vehicle to obtain an actuator control signal, the second end of the driving module 10 is suitable for being electrically connected to the actuator 20, and the driving module 10 is used to drive the actuator 20 according to the actuator control signal.

[0024] In this configuration, the drive module 10, the actuator 20 and the actuator control unit 40 work together to realize the normal operation of the powertrain 100. Specifically, after receiving the instruction, the actuator control unit 40 performs a logical judgment to determine whether the actuator 20 needs to perform a related operation, and then converts the logical judgment result into a specific control signal and sends it to the control signal input end of the drive module 10; the drive module 10 is responsible for converting the control signal output by the actuator control unit 40 into an actual drive current for output to drive the actuator 20 to perform a related operation. At the same time, the drive module 10 will also transmit a feedback signal to the actuator control unit 40 after the actuator 20 is running, so as to facilitate the actuator control unit 40 to adjust the control signal in real time. The actuator control unit 40, the drive module 10 and the actuator 20 cooperate with each other in the power transmission system of the vehicle 1000, and can jointly realize the smooth starting, speed change and braking operations of the vehicle 1000, and can ensure the normal driving function of the vehicle 1000.

[0025] Furthermore, by making the drive module 10 suitable for being arranged on the powertrain 100 including the actuator 20, and the actuator control unit 40 suitable for being arranged on the whole vehicle, not only is the structure simple, but the drive module 10 can also be separated out. When the driving power required by the actuator 20 is large, if the wiring harness between the drive module 10 and the actuator 20 cannot meet the large driving power requirement of the actuator 20, it is only necessary to change the wiring harness arrangement between the drive module 10 and the actuator 20 to meet the driving power requirement of the actuator 20, without changing the design and arrangement of the wiring harness of the whole vehicle, which is conducive to the platformization of the whole vehicle controller 200 and can reduce the development cost and production cost of the vehicle 1000.

[0026] Therefore, by making the drive module 10 suitable for being arranged on the powertrain 100 including the actuator 20, and making the first end of the drive module 10 suitable for being electrically connected to the actuator control unit 40 on the whole vehicle to obtain the actuator control signal, the second end of the drive module 10 is suitable for being electrically connected to the actuator 20, and the drive module 10 is used to drive the actuator 20 according to the actuator control signal. This not only has a simple structure, but also allows the power drive circuit to be independently arranged, which is beneficial to optimizing the structural arrangement of the actuator control unit 40 and the drive module 10, and is beneficial to the platformization of the existing whole vehicle controller 200. Moreover, there is no need to change the design and layout of the whole vehicle wiring harness, which can shorten the development cycle of the vehicle 1000 and reduce the development cost of the vehicle 1000.

[0027] It should be noted that the actuator 20 may include but is not limited to devices with relatively large power requirements such as electromagnetic clutch 201 and electromagnetic differential lock; the powertrain 100 can be understood as an assembly including a power source and a transmission device, including but not limited to a motor powertrain, an engine powertrain and a motor-engine hybrid powertrain.

[0028] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the drive module 10 includes: a drive unit 101 and a shell 102, the shell 102 is suitable for being fixed on the power assembly 100, the drive unit 101 is arranged in the shell 102, the first end of the drive unit 101 is suitable for being electrically connected to the actuator control unit 40 on the vehicle to obtain an actuator control signal, the second end of the drive unit 101 is suitable for being electrically connected to the actuator 20, and the drive unit 101 is used to drive the actuator 20 according to the actuator control signal.

[0029] Specifically, by arranging the drive unit 101 in the housing 102, it is not only convenient to integrate the drive module 10, but also to provide protection and support for the drive unit 101, to prevent dust, moisture, etc. from affecting the drive unit 101, and to provide structural strength to resist the impact and vibration generated during the driving of the vehicle 1000, and to prevent the internal components from being damaged by mechanical stress. Arranging the drive unit 101 in the housing 102 helps to improve the stability and reliability of the structural setting and line setting of the drive unit 101. In addition, it is also convenient to install and maintain the drive module 10, and it can also provide necessary electrical isolation to prevent electric shock accidents and ensure the safety of personnel.

[0030] Furthermore, the housing 102 is suitable for being fixed on the powertrain 100, so that the drive module 10 can be integrated into the powertrain 100, which can help to separate the drive module 10, help to shorten the electrical connection path between the drive module 10 and the actuator 20, and at the same time improve the compactness of the structure of the powertrain 100.

[0031] Furthermore, the driving unit 101 is arranged inside the housing 102 of the driving module 10, and the driving function of the driving module 10 is mainly realized by the driving unit 101, by making the first end of the driving unit 101 suitable for electrical connection with the actuator control unit 40 on the whole vehicle, and making the second end of the driving unit 101 suitable for electrical connection with the actuator 20, wherein the driving unit 101 is used to drive the actuator 20 according to the actuator control signal, thereby ensuring the normal transmission of circuit signals between the driving unit 101 and the actuator 20 and the actuator control unit 40, and ensuring that the driving unit 101 can receive the actuator control signal transmitted by the actuator control unit 40 through the electrical connection line between the driving unit 101 and the actuator control unit 40. After the internal circuit of the driving unit 101 performs processes such as signal processing and signal conversion, the driving signal can be output, and the driving signal is transmitted to the actuator 20 through the electrical connection line between the driving unit 101 and the actuator 20, so as to drive the actuator 20 to complete the required action. Such an arrangement can ensure that the driving unit 101 can effectively perform the driving function, and can ensure normal coordination between the actuator control unit 40, the driving unit 101, and the actuator 20 to meet different driving requirements of the vehicle 1000.

[0032] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the shell 102 includes: an input interface 1021, the input interface 1021 connects the inner side and the outer side of the shell 102, and the input interface 1021 is at least suitable for matching and connecting with the vehicle device where the actuator control unit 40 is located; an output interface 1022, the output interface 1022 connects the inner side and the outer side of the shell 102, and the output interface 1022 is at least suitable for matching and connecting with the powertrain 100.

[0033] Specifically, by setting an input interface 1021 and an output interface 1022 on the shell 102, and making the input interface 1021 at least suitable for matching and connecting with the vehicle device where the actuator control unit 40 is located, and the output interface 1022 at least suitable for matching and connecting with the device of the powertrain 100 where the actuator 20 is located, this can not only make the connection between the drive module 10 and the actuator control unit 40 and the powertrain 100 simple, direct, stable and reliable, but also help ensure the stability of the drive module 10 after installation, and can also facilitate the installation and disassembly of the drive module 10, and facilitate subsequent maintenance and repair work.

[0034] Furthermore, the inner side of the shell 102 is the installation space for the drive unit 101. By making the input interface 1021 and the output interface 1022 connected to the inner and outer sides of the shell 102, the port of the drive unit 101 can be led out from the inner side of the shell 102 through the input interface 1021 and the output interface 1022, which can facilitate the electrical connection between the drive unit 101 and other devices in the drive module 10, reduce the difficulty of arranging the electrical connection lines between the drive module 10 and the actuator 20 and the actuator control unit 40 respectively, ensure the rationality of the structural setting of the drive module 10, and ensure the normal operation of the drive module 10.

[0035] In some embodiments of the present invention, auxiliary structures such as snap-on parts or snap-on holes may be provided on the input interface 1021 and the output interface 1022 to improve the stability and reliability of the connection between the power drive unit 101 and the actuator 20 and the actuator control unit 40 .

[0036] In some embodiments of the present invention, the projections of the input interface 1021 and the output interface 1022 in the first direction may be staggered, that is, spaced apart from each other, or may at least partially overlap with each other. The specific structure is adjusted according to factors such as specific space limitations and surrounding device layout to ensure the structural strength of the driving module 10 and the stability of the structural setting.

[0037] Combination Figure 3 , Figure 4 and Figure 5As shown, the drive unit 101 includes: an input terminal 1011, which is arranged in the input interface 1021 to be suitable for being electrically connected to the actuator control unit 40; and an output terminal 1012, which is arranged in the output interface 1022 to be suitable for being electrically connected to the actuator 20. Specifically, the input interface 1021 is arranged on the side of the drive unit 101 close to the actuator control unit 40. By arranging the input terminal 1011 of the drive unit 101 in the input interface 1021 to be suitable for being electrically connected to the actuator control unit 40, it can not only ensure the normal signal transmission between the drive unit 101 and the actuator control unit 40, but also receive the control signal from the actuator control unit 40 through the input terminal 1011 to control the signal processing and data processing inside the drive unit 101, and it also helps to shorten the electrical connection path, which is convenient for the drive unit 101 to be connected to the actuator control unit 40. The electrical connection line layout between the actuator control unit 40; the output interface 1022 is arranged on the side of the drive unit 101 close to the actuator 20, and the output terminal 1012 is inserted into the output interface 1022 to be suitable for electrical connection with the actuator 20. This not only ensures normal signal transmission between the drive unit 101 and the actuator 20, but also transmits the processed signal to the actuator 20 through the output terminal 1012 to achieve effective control of the actuator 20, and also helps to shorten the electrical connection path and facilitate the layout of the electrical connection line between the drive unit 101 and the actuator 20.

[0038] Such a configuration can not only facilitate the arrangement and installation of the input terminal 1011 and the output terminal 1012, but also improve the stability and reliability of the electrical connection between the input terminal 1011 and the output terminal 1012. At the same time, the input terminal 1011 and the output terminal 1012 are the key connection points for the drive unit 101 to interact with the outside world. It can also ensure that the drive unit 101 can accurately receive the commands of the actuator control unit 40 and effectively control the actuator 20, thereby ensuring the normal working performance of the drive unit 101.

[0039] Combination Figure 5As shown, the drive unit 101 also includes a signal feedback terminal 1013, which is arranged in the input interface 1021 to be suitable for electrical connection with the actuator control unit 40 on the vehicle; the drive unit 101 is used to feedback a signal to the actuator control unit 40 through the signal feedback terminal 1013. Specifically, by setting a signal feedback terminal 1013 at the input interface 1021 of the drive unit 101, and making the signal feedback terminal 1013 suitable for electrical connection with the actuator control unit 40 on the whole vehicle, the drive unit 101 can send a feedback signal to the actuator control unit 40 through the signal feedback terminal 1013. This can not only simplify the arrangement of the feedback line between the drive unit 101 and the actuator control unit 40 and shorten the electrical connection path, but also realize the comparison between the set output value of the drive unit 101 and the actual output value to realize error detection and facilitate subsequent correction. Furthermore, by continuously adjusting the control signal to reduce the output error of the drive unit 101, the actuator 20 can respond to changes faster and can also be maintained more stably at the desired operating point. Therefore, setting the signal feedback terminal 1013 can be beneficial to improving the overall stability and reliability of the powertrain 100, optimizing the overall performance of the powertrain 100, and improving the driving efficiency and driving effect.

[0040] Combination Figure 3 , Figure 4 and Figure 5 As shown, the drive unit 101 includes: a positive power connection terminal 1014 and a negative power connection terminal 1015. The positive power connection terminal 1014 is provided through the input interface 1021 or the output interface 1022, and is suitable for connecting to the positive electrode of the power supply. Specifically, by providing the positive power connection terminal 1014 at the input interface 1021 or the output interface 1022, and making it suitable for connecting to the positive electrode of the power supply, the drive unit 101 can be powered by the positive power connection terminal 1014 to ensure the normal operation of the drive unit 101. In addition, the positive power connection terminal 1014 can also be used as a high potential reference point to determine the voltage level of other nodes relative to it.

[0041] Furthermore, the negative power connection terminal 1015 is provided through the input interface 1021 or the output interface 1022, and is suitable for being connected to the negative pole of the power supply or being grounded. Specifically, by providing the negative power connection terminal 1015 at the input interface 1021 or the output interface 1022, and making it suitable for being connected to the negative pole of the power supply or being grounded, the current can be returned to the inside of the power supply of the drive unit 101 through the negative power connection terminal 1015, so as to form a complete closed loop.

[0042] Furthermore, if the negative power connection terminal 1015 is grounded, it can play a role in safety protection. When leakage occurs in the driving unit 101, the grounding terminal can introduce the current into the ground to prevent electric shock to the human body. In addition, the grounding terminal can also provide a common reference potential for the signal in the internal circuit of the driving unit 101 to improve the stability and reliability of the internal circuit of the driving unit 101 when it is working.

[0043] Combination Figure 1 and Figure 5 As shown, the powertrain 100 according to the present invention may mainly include: an actuator 20 and the above-mentioned drive module 10. Among them, the actuator 20 is electrically connected to the drive unit 101, and the actuator 20 is used to act according to the drive signal of the drive unit 101, so that the action or working mode of the actuator 20 can be accurately controlled by the drive signal output by the drive unit 101, and effective communication between the drive unit 101 and the actuator 20 can be achieved, so as to ensure that the actuator 20 can work in an expected manner, accurately control the start and stop of the actuator 20, improve the flexibility and adaptability of the powertrain 100, and realize the automatic control of the vehicle 1000.

[0044] Furthermore, since the structure of the driving module 10 is more independent and has good working performance, applying the driving module 10 to the powertrain 100 can not only improve the normal working performance of the powertrain 100, but also facilitate the platformization of the vehicle controller 200.

[0045] Combination Figure 1 , Figure 2 and Figure 5 As shown, the powertrain 100 further includes a box 30, and the actuator 20 is located in the box 30. Specifically, by arranging the actuator 20 in the box 30, it can not only provide necessary support for the actuator 20, but also provide necessary isolation to prevent electric shock accidents, ensure personnel safety, prevent the operation of certain components outside the box 30 from affecting the execution of related actions of the actuator 20 or the accuracy of signal reception, and prevent the related operations of the actuator 20 from affecting other components outside the box 30. In addition, it can also provide protection for the actuator 20 to prevent dust, moisture, etc. from affecting the actuator 20, and at the same time provide structural strength to resist the impact and vibration generated during the driving of the vehicle 1000, and prevent the components in the box 30 from being damaged due to mechanical stress.

[0046] Combination Figure 1 , Figure 2 and Figure 4As shown, the box body 30 is configured with a connection hole penetrating the inner side and the outer side thereof, the connection hole is matched and connected with the driving module 10 , and the actuator 20 is electrically connected with the driving unit 101 through the connection hole. Specifically, the actuator 20 is arranged in the box body 30, and the drive unit 101 is arranged on the outside of the box body 30. By constructing a connection hole that runs through the inside and outside of the box body 30, the connection hole of the box body 30 is suitable for matching and connecting with the output interface 1022 of the drive unit 101, so that the actuator 20 can be electrically connected to the drive unit 101 through the connection hole, which is mainly reflected in the electrical connection between the output terminal 1012 of the drive unit 101 and the drive signal receiving terminal of the actuator 20. In this way, the connection between the drive module 10 and the actuator 20 can be simplified, and the connection between the drive module 10 and the actuator 20 can be made more stable and reliable, preventing the drive module 10 from tilting or shaking after being installed and fixed, and ensuring stable signal transmission between the drive unit 101 and the actuator 20. It can also realize the rapid positioning of the installation position of the drive unit 101 on the box body 30, which can facilitate the installation and disassembly of the drive module 10.

[0047] Combination Figure 1 , Figure 4 and Figure 5 As shown, the actuator 20 includes an electromagnetic clutch 201 , and the electromagnetic clutch 201 includes an electromagnetic coil, which is electrically connected to the drive unit 101 .

[0048] Specifically, the electromagnetic coil controls the engagement and disengagement of the electromagnetic clutch 201 through electromagnetic force. When the electromagnetic coil is energized, the generated electromagnetic force will attract the armature, thereby achieving the engagement of the electromagnetic clutch 201. When the electromagnetic coil is de-energized, the electromagnetic force disappears, the armature is no longer attracted and returns to its previous position under the action of a reset structure such as a spring, thereby achieving the disengagement of the electromagnetic clutch 201. This can ensure the normal working performance of the electromagnetic clutch 201 and the normal working performance of the actuator 20.

[0049] Furthermore, the electromagnetic coil is electrically connected to the drive unit 101, so that normal transmission of electrical signals between the drive unit 101 and the electromagnetic coil can be achieved. The electromagnetic force generated by the electromagnetic coil can be regulated by the drive unit 101, thereby controlling the working state of the electromagnetic clutch 201 to achieve operations such as gear shifting and speed change of the vehicle 1000.

[0050] Furthermore, during assembly, the drive module 10 can be first installed at the connecting hole of the powertrain case 30 to make them one body, while ensuring the electrical connection between the drive unit 101 and the actuator 20 in the case 30, and then the drive module 10 and the actuator control unit 40 are connected and installed, while ensuring the electrical connection between the drive unit 101 and the actuator control unit 40.

[0051] Combination Figure 1 , Figure 2 and Figure 4 As shown, a sealing ring 1023 is sleeved on the output interface 1022 of the drive module 10, and the sealing ring 1023 is in sealing contact with the connecting hole, which can not only improve the installation accuracy of the drive module 10, improve the sealing performance of the powertrain case 30, and prevent the oil in the case 30 from leaking out, but also prevent foreign matter such as gas and liquid from entering the gap between the connecting hole and the drive module 10, so as to prevent the foreign matter from affecting the normal operation of the circuit and preventing the foreign matter from causing wear of the components. In addition, the provision of the sealing ring 1023 can also make the installation of the drive module 10 more stable, prevent the drive module 10 from shaking or deflecting after installation and fixation, reduce the wear between the connecting hole and the drive module 10, and reduce the wear or bump between the edge of the connecting hole and the top of the output interface 1022 of the drive module.

[0052] Combination Figure 1 and Figure 5 As shown, the vehicle 1000 according to the present invention may mainly include: the above-mentioned powertrain 100 and a vehicle controller 200. The vehicle controller 200 includes an actuator control unit 40, which is electrically connected to the drive unit 101 of the powertrain 100 to send an actuator control signal to the drive unit 101.

[0053] Specifically, the vehicle controller 200 is responsible for the management and coordination of the overall system within the vehicle 1000 to ensure the coordinated work between the various subsystems within the vehicle 1000. The vehicle controller 200 is connected to the actuator control unit 40 and there is signal transmission between the two. The actuator control unit 40 can be integrated into the vehicle controller 200. This not only facilitates the connection between the vehicle controller 200 and the actuator control unit 40, but also improves the integration of the vehicle 1000 structure and improves space utilization. In addition, it is conducive to the platformization of the integrated structure of the vehicle controller 200 and the actuator control unit 40, which can reduce the development cost and production cost of the vehicle 1000.

[0054] Furthermore, the actuator control unit 40 is electrically connected to the drive unit 101 of the powertrain 100 to send an actuator control signal to the drive unit 101, and can generate a total driving demand based on the overall operating conditions of the vehicle 1000 and the driver's intention. The actuator control unit 40 can generate a control signal based on the instructions of the vehicle controller 200 and transmit it to the drive unit 101. The drive unit 101 can convert the received control signal into an actual driving current for output, so that the actuator 20 completes the required action to meet the different driving requirements of the vehicle 1000.

[0055] Furthermore, since the powertrain 100 has a more compact structure and good working performance, applying the powertrain 100 to the vehicle 1000 can simplify the relevant structure of the vehicle 1000, and the power drive circuit can be set independently, which can be beneficial to the platformization of the existing vehicle controller 200. When the driving power demand of the actuator 20 is large, there is no need to change the design and layout of the vehicle wiring harness, which can shorten the development cycle of the vehicle 1000 and reduce the development cost of the vehicle 1000.
