[0014] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0017] Please see Figure 1 , Figure 1 This is a structural schematic diagram of an embodiment of the integrated power pack provided in this application. The integrated power pack 10 includes an energy storage module 11, a power module 12, and a control module 13.

[0018] The energy storage module 11 is used to store electrical energy based on an external power supply signal and convert the electrical energy to obtain a power supply signal. Specifically, an external charging device or an external power source (not shown in the figure) can provide an external power supply signal to the energy storage module 11 to charge the energy storage module 11. The energy storage module 11 can also perform energy conversion to convert electrical energy into a power supply signal required by other modules to power other modules.

[0019] In one specific implementation, the energy storage module 11 can also manage the electrical energy it stores, respond promptly to the energy needs of other modules, maintain its own energy balance and thermal balance, and promptly acquire an equal amount of external power supply signal when electrical energy is converted into a power supply signal output, so as to achieve energy balance of charging and discharging.

[0020] The power module 12 is connected to the energy storage module 11. It is used to convert the power supply signal into a mechanical energy signal and input the mechanical energy signal to an external drive device (not shown in the figure) to drive the external drive device to run. Specifically, the external drive device can be a device driven by mechanical energy, such as a drive wheel or gear. Taking the drive wheel in a car as an example, after receiving the power supply signal, the power module 12 can convert the power supply signal into a mechanical energy signal and input it into the drive wheel to provide power to the drive wheel so that the drive wheel runs.

[0021] The control module 13 is connected to the energy storage module 11 and the power module 12. It is used to adjust the amplitude of the power supply signal and / or the amplitude of the mechanical energy signal based on the control command, thereby adjusting the operating state of the external drive device. Specifically, the control command can be the control command input by the user / manager through the interactive panel (not shown in the figure) for information interaction with the control module 13, or it can be the control command generated by the control module 13 according to its own control logic. No limitation is made here.

[0022] Furthermore, the control module 13 can output corresponding control signals to the energy storage module 11 based on control commands, thereby controlling the amplitude of the power supply signals output by the energy storage module 11 to other modules, and thus allocating the energy output of the energy storage module 11. The control module 13 can also output corresponding control signals to the power module 12 based on control commands to control the amplitude of the mechanical energy signals output by the power module 12, thereby adjusting the motion state of the external drive device, such as adjusting the running speed, running acceleration, or torque of the external drive device. For example, taking the drive wheels of a car as an example, mechanical energy signals of different amplitudes acting on the drive wheels can determine the torque, running speed, or running direction of the drive wheels, thereby directly affecting the car's speed or acceleration and other operating parameters. Therefore, by controlling the amplitude of the mechanical energy signals, the operating state of the external drive device can be controlled.

[0023] In one specific embodiment, the control module 13 can also monitor the energy storage module 11 and the power module 12, and provide timely feedback and processing when the energy storage module 11 and / or the power module 12 malfunction, thereby improving the stability and safety of the integrated power pack 10.

[0024] This embodiment integrates three modules: energy storage, power, and control. This integrated power pack combines energy storage, motor, and electronic control functions, eliminating the need for numerous components to achieve a single function. It solves the problem of strong component design interrelationships. Furthermore, the high integration of the integrated power pack simplifies wiring, saves space, and reduces costs. In addition, the highly integrated power pack can be directly applied to various electromechanical equipment on the market, offering high versatility and ease of operation. It can meet users' customized needs and significantly reduce the design cycle and complexity of the entire equipment, saving considerable manpower and resources.

[0025] Please see Figure 2 , Figure 2 This is a structural schematic diagram of another embodiment of the integrated power pack provided in this application. The integrated power pack 20 can be applied to electromechanical equipment, which includes an external drive device 31 and other electrical devices 32. Specifically, the electromechanical equipment can be a car or a crane, etc. (the following embodiment uses a car as an example for explanation). Other electrical devices 32 can be a display panel, air conditioner, or lights, etc. The integrated power pack 20 can provide power to the external drive device 31 in the electromechanical equipment, and at the same time control the working state of the external drive device 31 and other electrical devices 32. By adopting an integrated design, the strong correlation between the power pack and the frame can be decoupled, so as to realize the adaptation of the integrated power pack 20 to various different frames and meet the user's frame customization needs.

[0026] The integrated power pack 20 may include an energy storage module 21, a power module 22, and a control module 23. Specifically, the energy storage module 21 is used to store electrical energy based on an external power supply signal and convert the electrical energy to obtain a power supply signal. The power module 22 is connected to the energy storage module 21 and is used to convert the power supply signal into a mechanical energy signal and input the mechanical energy signal to the external drive device 31 to drive the external drive device 31 to operate. The control module 23 is connected to the energy storage module 21 and the power module 22 and is used to adjust the amplitude of the power supply signal and / or the amplitude of the mechanical energy signal based on control commands, thereby adjusting the operating state of the external drive device 31.

[0027] In one specific embodiment, such as Figure 3 As shown, there can be multiple energy storage modules 21. All energy storage modules 21 can be set on one side of the integrated power pack 20, while the power module 22 and control module 23 are set on the other side of the integrated power pack 20. By concentrating the energy storage modules 21 on one side of the integrated power pack 20, the energy transmission distance between the energy storage modules 21 can be effectively reduced, thereby reducing energy transmission loss. At the same time, setting the power module 22 and control module 23 on the other side of the integrated power pack 20 is conducive to the design of centralized external interfaces, thereby enhancing the protection of the integrated power pack 20.

[0028] Understandably, the number of energy storage module 21, power module 22 and control module 23 can be set according to actual conditions and needs, and is not limited here. Generally speaking, the more energy storage modules 21 there are, the better the energy storage function of the integrated power pack 20 will be. The more power modules 22 and control modules 23 there are, the more power will be provided and the better the control effect will be, which can be specifically manifested in the acceleration effect of the car.

[0029] In another specific embodiment, the control instructions may include a first control instruction and a second control instruction, such as... Figure 2 As shown, the control module 23 may include a main control unit 231 and an auxiliary control unit 232. The main control unit 231 is connected to the power module 22 and is used to generate a first control signal based on a first control command and input it to the power module 22 to adjust the amplitude of the mechanical energy signal. The auxiliary control unit 232 is connected to the main control unit 231 and other electrical devices 32 and is used to generate a second control signal based on a second control command and input it to the other electrical devices 32 to adjust the working state of the other electrical devices 32.

[0030] Furthermore, different control commands can correspond to different priority levels. The priority level of the first control command is higher than that of the second control command. That is, the main control unit 231 is used to execute the first control command with higher priority, such as activating the car's autonomous driving mode. If the user inputs the first control command to activate the autonomous driving mode, the main control unit 231 can output a corresponding first control signal to the power module 22 to adjust the amplitude of the mechanical energy signal output by the power module 22, control the operating state of the external drive device 31, and adjust the external drive device 31 to autonomous driving mode. The auxiliary control unit 232 is used to execute control commands with lower priority, such as turning the air conditioner on / off, playing music, or turning the windshield wipers on / off. The auxiliary control unit 232 can output a corresponding second control signal to other electrical devices 32 according to the second control command, thereby adjusting the working state of other electrical devices 32. Understandably, the priority level represents the importance of the control command. Generally, the priority level of control commands related to adjusting the vehicle's driving mode is higher than the priority level of commands related to adjusting the working state of other electrical devices 32.

[0031] In another specific embodiment, the auxiliary control unit 232 is also used to monitor whether other electrical devices 32 have malfunctioned based on safety parameters; when other electrical devices 32 malfunction, it determines whether the difficulty level of handling the current fault exceeds a first preset level, which can be set according to the actual situation; if the difficulty level of handling the current fault is less than or equal to the first preset level, the auxiliary control unit 232 controls the other electrical devices 32 to restart or shut down; if the difficulty level of handling the current fault exceeds the first preset level, the auxiliary control unit 232 generates a first fault signal based on the current fault and feeds the first fault signal back to the main control unit 231 so that the main control unit 231 can obtain the first fault handling strategy; by monitoring other electrical devices 32 through the auxiliary control unit 232, it is possible to handle faults in a timely manner when they are detected, thereby enabling the control of the entire electromechanical equipment while monitoring the faults of other electrical devices 32 in the entire electromechanical equipment, thereby improving the safety and reliability of the entire electromechanical equipment. Understandably, the first fault handling strategy can be a fault handling strategy obtained by the main control unit 231 by looking up its own pre-set strategy table, or it can be a fault handling strategy input by the user / manager. There is no limitation here.

[0032] In one embodiment, safety parameters may include current, voltage, or temperature, and the fault conditions may include overvoltage, overcurrent, short circuit, excessive temperature, or device damage. The auxiliary control unit 232 can monitor other electrical devices 32 and determine whether a fault condition has occurred based on parameters such as current, voltage, or temperature of the other electrical devices 32.

[0033] When other electrical devices 32 malfunction, the auxiliary control unit 232 can choose to resolve the issue itself or seek assistance from the main control unit 231 based on the difficulty level of the current fault. If the fault is relatively easy to resolve, the auxiliary control unit 232 can control the malfunctioning electrical device 32 to restart or shut down, thus resolving the fault. However, if the fault is more complex and the auxiliary control unit 232 cannot resolve it independently, it can generate a first fault signal containing fault information (including the type of fault and the location of the malfunctioning device) and feed it back to the main control unit 231. This allows the main control unit 231 to respond to the auxiliary control unit 232's request for assistance and provide a first fault handling strategy. Understandably, if the fault is relatively easy to resolve and the auxiliary control unit 232's independent resolution is ineffective, the auxiliary control unit 232 can also feed back a first fault signal to the main control unit 231 to seek its assistance.

[0034] The main control unit 231 can also be used to monitor whether the energy storage module 21 and the power module 22 have failed based on safety parameters, and generate a second fault signal when the energy storage module 21 and / or the power module 22 fails; that is, the main control unit 231 can monitor other modules in the integrated battery pack in real time, further improving the reliability and safety of the integrated power pack 20 itself.

[0035] In another specific embodiment, the control module 23 further includes a communication unit 233, which is connected to the main control unit 231 and an external communication unit (not shown in the figure). The communication unit 233 is used to feed back the first fault signal and / or the second fault signal to the external communication unit to obtain the second fault handling strategy sent by the external communication unit. The signal transmission speed between the communication unit 233 and the main control unit 231 can reach tens of MB / s. By setting up the communication unit 233 to communicate with the external communication unit, the fault information can be fed back to the user / management personnel in a timely manner when an unresolved fault occurs, so as to realize the timely recording and resolution of fault information, and can minimize the user's usage and maintenance costs.

[0036] Furthermore, the external communication unit can be a device that can communicate with the communication unit 233 inside the integrated power pack 20. The external communication unit can be an interactive panel or cloud device on the electromechanical equipment, or a mobile terminal such as a mobile phone or computer, which is not limited here. The external communication unit may include a display panel, which can display the corresponding fault information on the display panel after receiving the first fault signal and / or the second fault signal. Users / managers can view the fault information through the display panel, and select an appropriate fault handling strategy, i.e., the second fault handling strategy, according to the fault information. The second fault handling strategy is then fed back to the communication unit 233 inside the integrated power pack 20 through the external communication unit, so that the main control unit 231 can perform corresponding control according to the second fault handling strategy.

[0037] Understandably, when a fault occurs in the energy storage module 21 and / or the power module 22, the main control unit 231 can also choose whether it can resolve the fault itself based on the difficulty level of the current fault. When the difficulty level of the current fault is low, the main control unit 231 can select an appropriate fault handling strategy by looking up its own pre-set strategy table. When the main control unit 231 fails to resolve the fault itself or the difficulty level of the current fault is high, the main control unit 231 can send a second fault signal to the communication unit 233 to relay the fault information to the user / manager. Similarly, when the auxiliary control unit 232 encounters a fault that it cannot resolve and the main control unit 231 cannot resolve either, it can send a second fault signal to the communication unit 233 through the main control unit 231, thereby relaying the fault information of the current fault to the user / manager through the communication unit 233 to obtain a second fault handling strategy.

[0038] In another specific embodiment, the main control unit 231 can also monitor whether the auxiliary control unit 232 has failed based on safety parameters. When the auxiliary control unit 232 fails, a third fault signal is generated, and it is determined whether the difficulty level of handling the current fault exceeds the second preset level. If the difficulty level of handling the current fault is less than or equal to the second preset level, the auxiliary control unit 232 is restarted or shut down. If the difficulty level of handling the current fault exceeds the second preset level, the third fault signal is sent to the communication unit 233, so that the communication unit 233 feeds back the third fault signal to the external communication unit, thereby obtaining the third fault handling strategy sent by the external communication unit.

[0039] Furthermore, the main control unit 231 can perform individual power management on each auxiliary control unit 232. That is, the main control unit 231 can control the on / off of each auxiliary control unit 232. When one or more auxiliary control units 232 fail, the main control unit 231 can choose to restart or shut down one or more auxiliary control units 232. At the same time, the main control unit 231 takes over the tasks of the auxiliary control unit 232 due to the failure, so as to avoid the failure affecting the normal operation of the integrated power pack 20.

[0040] In another specific embodiment, the energy storage module 21 may include an energy storage unit 211 and a management unit 212; the energy storage unit 211 can store electrical energy based on an external power supply signal and output a power supply signal; the management unit 212 is connected to the energy storage unit 211 and the control module 23, and is used to receive a third control signal output by the control module 23, and to distribute electrical energy based on the third control signal to adjust the amplitude of the power supply signal; specifically, the management unit 212 can distribute and manage the electrical energy stored in the energy storage module 21, and at the same time, the management unit 212 can also maintain the charging and discharging balance and thermal balance of the energy storage unit 211, so that the energy storage unit 211 is in an energy balance state and a thermal balance state.

[0041] like Figure 4 As shown, the management unit 212 corresponds one-to-one with the energy storage unit 211. The management unit 212 may include a first communication module (not shown in the figure), and the energy storage unit 211 may include a second communication module (not shown in the figure). The first communication module and the second communication module communicate through a wireless network (such as WIFI or Bluetooth). The wireless communication method can reduce the cost of the internal wiring harness between the management unit 212 and the energy storage unit 211 and the risk of failure, thereby improving the robustness of the integrated power pack 20.

[0042] In other implementations, such as Figure 5 As shown, the management unit 212 and the energy storage unit 211 can also be connected via wired communication. The number and arrangement of the management unit 212 and the energy storage unit 211 can be designed according to the functional safety and thermal cycle factors of the integrated power pack 20, and are not limited here.

[0043] Furthermore, the management unit 212 can also monitor whether the energy storage unit 211 has malfunctioned based on safety parameters; when the energy storage unit 211 malfunctions, it generates a fourth fault signal and feeds it back to the control module 23 so that the control module 23 can obtain a fourth fault handling strategy. Understandably, the fourth fault handling strategy can be obtained by the control module 23 according to its own pre-set strategy table, or it can be fed back to the control module 23 by the user / manager through an external communication unit; this is not limited here.

[0044] In other specific embodiments, the integrated power pack 20 may also include an expansion interface (not shown in the figure), which is connected to an external device (not shown in the figure) for receiving signals sent by the external device and / or sending signals to the external device. This allows for the addition of other expansion modules based on the original design of the integrated power pack 20, enriching the user's different functional requirements and the overall expansion requirements of the device.

[0045] The integrated power pack in this embodiment adopts an integrated design, decoupling it from the strong correlation with the vehicle frame. This allows for flexible matching of the integrated power pack with different vehicle frames to meet customized user needs. It also significantly reduces redundant component design, shortens the design cycle and complexity, and increases functional safety. Through a well-designed structural space layout of the energy storage module, power module, and control module from a reliability and safety perspective, it not only enhances the reliability of internal signal line transmission but also solves most electromagnetic compatibility issues, improves the utilization rate of the thermal cycling system, and enhances system robustness. Furthermore, the integrated power pack can achieve fault diagnosis and self-repair of itself and the entire electromechanical equipment. The main control unit can simultaneously take over the interrupted tasks of the auxiliary control unit in a multi-threaded manner when the auxiliary control unit fails, improving the stability of the integrated power pack. Furthermore, when the integrated power pack cannot self-repair, it can communicate with an external communication unit to promptly report fault information to users / managers, enabling timely acquisition of appropriate handling strategies. This enhances the safety and stability of the integrated power pack and the entire electromechanical equipment, minimizing user operating and maintenance costs. In addition, the integrated power pack has ample expansion interfaces, allowing for the addition of other expansion modules based on the original integrated power pack design, enriching users' diverse expansion function needs.

[0046] Please see Figure 6 , Figure 6 This is a schematic diagram of the structure of an embodiment of the electromechanical equipment provided in this application. The electromechanical equipment 60 includes an integrated power pack 61, wherein the integrated power pack 61 is the integrated power pack in the above embodiment.

Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
