Description

Technical Field

[0001] This utility model relates to the field of new energy technology, and in particular to a new energy power system for non-road mobile machinery. Background Technology

[0002] Non-road mobile machinery (such as construction machinery, agricultural machinery, and port machinery) is an important piece of equipment in national economic construction, and traditionally it mostly uses internal combustion engines such as diesel engines and gasoline engines as its power source. This type of power system has the following significant problems:

[0003] Severe environmental pollution: When internal combustion engines burn fossil fuels, they emit large amounts of pollutants such as nitrogen oxides (NOx), particulate matter (PM), and carbon monoxide (CO), which is one of the major sources of air pollution. Especially in enclosed or semi-enclosed working environments (such as workshops, warehouses, and underground projects), it can have a serious impact on the health of operators and the surrounding environment.

[0004] High energy consumption and high operating costs: Internal combustion engines have low thermal efficiency (usually only 30%-40%), high fuel consumption, and high operating costs in the long term due to fluctuations in fuel prices.

[0005] Noise pollution is a significant issue: the mechanical vibration and exhaust noise generated during the operation of internal combustion engines can easily cause occupational health hazards to operators, and at the same time, it can cause noise interference to the surrounding environment.

[0006] Complex maintenance: Internal combustion engines have a precise structure and contain many mechanical transmission components. Routine maintenance requires frequent replacement of consumables such as engine oil and filters. The maintenance cycle is short, the cost is high, and mechanical wear can easily lead to malfunctions and downtime.

[0007] Limited starting performance: Traditional internal combustion engines are difficult to start in low-temperature environments, requiring additional preheating devices, which affects operating efficiency; moreover, they are highly dependent on batteries during the starting process, and are prone to starting failure due to battery depletion.

[0008] In recent years, the application of new energy technologies in the field of non-road mobile machinery has gradually begun, but existing electric drive systems still have many shortcomings: such as an imperfect battery management system, insufficient range and power output stability; reliance on the main battery for starting, leading to faster main battery wear; low system integration and weak coordination and control capabilities of various components; lack of intelligent monitoring and remote management functions, resulting in low operation and maintenance efficiency. Therefore, there is an urgent need for a high-efficiency, environmentally friendly, stable, and intelligent new energy power system to solve the pain points of traditional power systems. Utility Model Content

[0009] In view of the problems existing in the prior art, this utility model provides a new energy power system for non-road mobile machinery.

[0010] To achieve the above objectives, the technical solution of this utility model is as follows:

[0011] This utility model provides a new energy power system for non-road mobile machinery, including: a frame, a rechargeable battery, a drive mechanism controller, a drive mechanism, a charger, a starting sodium battery, an ECU controller, a DC / DC module, a horn, a wireless module, and a display module placed on the frame;

[0012] The drive mechanism is located on one side of the rechargeable battery, and the drive mechanism controller, starting sodium battery, ECU controller, DC / DC module, speaker, wireless module, and display module are all located above the drive mechanism; the charger is located above the starting sodium battery.

[0013] The corresponding terminals of the ECU controller are electrically connected to the corresponding terminals of the DC / DC module, speaker, wireless module, display module, drive mechanism controller, and charger, respectively.

[0014] The drive mechanism controller is electrically connected to the corresponding end of the drive mechanism; the corresponding end of the charger is electrically connected to the rechargeable battery; the starting sodium battery is electrically connected to the ECU controller, the drive mechanism controller, the drive mechanism, and the charger respectively.

[0015] Preferably, the input terminal of the DC / DC module is electrically connected to the rechargeable battery, and the output terminal provides an adaptive operating voltage for the speaker, wireless module, and display module.

[0016] Preferably, the drive mechanism includes a drive motor, the output of which is used to connect to an external hydraulic pump.

[0017] Preferably, the drive mechanism controller is a motor controller, used to control the speed and torque of the drive motor.

[0018] Preferably, the wireless module includes a Bluetooth DTU module, which is used for wireless data transmission with an external smart terminal.

[0019] Preferably, the display module includes a display screen or a touch display screen.

[0020] Preferably, the connection lines between the rechargeable battery, drive motor, ECU controller, motor controller, charger, and starting sodium battery are wrapped with multiple corrugated pipes.

[0021] Preferably, the rechargeable battery includes a lithium battery cell and a BMS protection board; the BMS protection board is electrically connected to the ECU controller.

[0022] The technical solution of this utility model has the following beneficial effects:

[0023] This utility model is green and environmentally friendly, reducing pollution: it uses a rechargeable battery and drive motor to replace the traditional internal combustion engine, achieving zero exhaust emissions during power output, solving the air pollution problem of non-road mobile machinery from the source, and is especially suitable for operation in enclosed places with strict environmental protection requirements (such as indoor warehouses and underground projects), which is in line with the national "dual carbon" strategy and environmental protection policies.

[0024] This invention can reduce operating costs and improve economic efficiency: electric drive has lower energy consumption costs than fuel drive (electricity prices are usually lower than fuel prices), and the motor structure is simple with fewer moving parts. Routine maintenance only requires checking the battery and controller, eliminating the need for frequent replacement of consumables such as oil and filters, thus significantly reducing long-term maintenance costs.

[0025] This invention provides reliable startup and extends the life of the main battery: an independent starting sodium battery is set up, which takes advantage of the excellent low-temperature performance and low cost of sodium batteries to provide initial power for system startup, avoid damage to the main battery (rechargeable battery) due to instantaneous high current discharge, extend the life of the main battery, and solve the problem of difficult startup in low-temperature environments.

[0026] This invention features intelligent control, enhancing operational stability: Centered on an ECU controller, it achieves centralized monitoring and coordinated control of components such as the drive mechanism, battery, and charger; through linkage with the BMS protection board, it monitors the rechargeable battery status (charge, voltage, temperature, etc.) in real time, preventing overcharging and over-discharging and ensuring battery safety; the drive mechanism controller precisely regulates the speed and torque of the drive motor, ensuring accurate matching of power output with the workload and reducing energy waste; combined with a display module, it provides real-time feedback of system operating parameters (such as battery status and fault codes), allowing operators to promptly grasp the equipment status.

[0027] This invention enhances the safety and reliability of the system: the connecting lines of each component are wrapped with corrugated pipes, which effectively protects the lines from vibration, friction, dust and moisture, reducing the risk of short circuits and leakage; the speaker module can promptly issue an alarm signal when the system malfunctions (such as battery failure or overload), improving operational safety.

[0028] This utility model can support remote management and improve operation and maintenance efficiency: the wireless module (such as Bluetooth DTU module) can realize data interaction with external smart terminals (mobile phone, tablet, computer), support remote uploading of equipment operation data and receiving control commands, which makes it convenient for managers to remotely monitor equipment status, provide early warning of faults, and reduce on-site maintenance costs.

[0029] In summary, this utility model, through integrated design, intelligent control, and optimized application of new energy technologies, comprehensively improves the environmental friendliness, economy, reliability, and intelligence level of non-road mobile machinery, making it suitable for promotion and application in various non-road scenarios.

[0037] Reference Figures 1 to 2 This utility model provides a new energy power system for non-road mobile machinery, including: a frame, a rechargeable battery 1, a drive mechanism controller 2, a drive mechanism 3, a charger 4, a starting sodium battery 5, an ECU controller 6, a DC / DC module 7, a horn 8, a wireless module 20, and a display module 9 placed on the frame;

[0038] The drive mechanism 3 is located on one side of the rechargeable battery 1. The drive mechanism controller 2, the starting sodium battery 5, the ECU controller 6, the DC / DC module 7, the speaker 8, the wireless module 20, and the display module 9 are all located above the drive mechanism 3. The charger 4 is located above the starting sodium battery 5. The ECU controller 6, the DC / DC module 7, the speaker 8, the wireless module 20, and the display module 9 are all located at the front end of the drive mechanism controller 2 and the starting sodium battery 5.

[0039] The corresponding terminals of the ECU controller 6 are electrically connected to the corresponding terminals of the DC / DC module 7, the horn 8, the wireless module, the display module 9, the drive mechanism controller 2, and the charger 4, respectively. The ECU controller 6 can transmit control signals (such as display data and alarm commands) to the display module 9 and the horn 8. The wireless module 20 can realize wireless signal interaction between the ECU controller and the remote terminal (uploading operating data and receiving remote commands).

[0040] The drive mechanism controller 2 is electrically connected to the corresponding end of the drive mechanism 3; the corresponding end of the charger 4 is electrically connected to the rechargeable battery 1; the charger 4 is connected to an external power source to replenish the rechargeable battery 1, and is also electrically connected to the ECU controller 6, so that the ECU controller 6 can monitor the charging status (such as charging current, progress, etc.) and ensure the safety and controllability of the charging process.

[0041] The starting sodium battery 5 is electrically connected to the ECU controller 6, the drive mechanism controller 2, the drive mechanism 3, and the charger 4. The starting sodium battery 5 provides initial power during the start-up phase of the drive mechanism 3, assisting in its rapid start-up. After start-up, it switches to the rechargeable battery 1 for power, reducing the instantaneous load on the rechargeable battery 1, extending its lifespan, and improving the reliability of system startup. The ECU controller 6 communicates bidirectionally with the drive mechanism controller 2, sending speed control and start / stop commands and receiving motor status feedback.

[0042] Furthermore, the input terminal of the DC / DC module 7 is electrically connected to the rechargeable battery 1, and the output terminal provides an appropriate operating voltage to the speaker 8, wireless module 20, and display module 9 to ensure the normal operation of low-voltage equipment and realize the rational distribution of electrical energy. When the system malfunctions (such as battery abnormality), the speaker 8 receives the instruction from the ECU controller 6 and issues an alarm signal to serve as a warning. The display module 9 is used to receive signals from the ECU controller 6 and display information such as the status of the rechargeable battery 1 and the starting sodium battery 5, the working parameters of the drive mechanism 3, and fault codes, so that operators can understand the system operation status in real time.

[0043] Furthermore, the drive mechanism 3 includes a drive motor, the output end of which is used to connect to an external hydraulic pump to provide power for the movement and operation of the non-road mobile machinery, which is more in line with energy conservation and emission reduction requirements compared with traditional diesel engine drive.

[0044] Furthermore, the drive mechanism controller 2 is a motor controller. The drive mechanism controller 2 receives instructions from the ECU controller 6 to specifically control the speed and torque of the drive motor, so that the drive motor outputs power that is adapted to the operation requirements of non-road mobile machinery, and ensures the accuracy and stability of power output.

[0045] Furthermore, the wireless module 20 includes a Bluetooth DTU module, which is used for wireless data transmission with external smart terminals.

When a system malfunctions, the problem can be quickly located through the displayed fault information, facilitating timely maintenance and handling. This improves the system's operability and maintenance efficiency, and ensures the stable operation of the non-road mobile machinery's new energy power system.

[0047] Furthermore, the connection lines between the rechargeable battery 1, drive motor, ECU controller 6, motor controller, charger 4, and starting sodium battery 5 are wrapped by multiple corrugated pipes 10. The corrugated pipes 10 serve to centrally organize and physically protect the scattered lines, preventing them from being damaged during equipment operation due to vibration, friction, or external environmental factors (such as dust and moisture), while also reducing energy loss and signal interference caused by messy wiring.

[0048] Furthermore, the rechargeable battery includes lithium battery cells and a BMS protection board; the BMS protection board is electrically connected to the ECU controller and is used to monitor the battery status (such as charge, voltage, temperature, etc.) to ensure the safe and stable operation of the battery, while also helping to improve the system's energy utilization rate.

[0049] The working principle of this utility model is as follows:

[0050] The rechargeable battery 1 is replenished with power by the charger 4. The sodium battery 5 provides initial power during the start-up phase of the drive mechanism 3. After start-up, the power supply is switched back to the rechargeable battery 1 for continuous operation. The ECU controller 6 acts as the control center, receiving status signals from various components (such as battery level and drive mechanism load) and sending commands to the drive mechanism controller 2, horn 8, display module 9, etc., to coordinate the operation of various components.

[0051] The drive mechanism controller 2 receives instructions from the ECU controller 6 to regulate the speed and torque of the drive motor, converting electrical energy into mechanical energy to drive external working devices (such as hydraulic pumps). The DC / DC module 7 converts the high-voltage electrical energy from the battery into the working voltage suitable for low-voltage components (speaker 8, display module 9, wireless module, etc.) to ensure their normal operation.

[0052] The wireless module enables wireless communication between the ECU controller 6 and an external smart terminal, uploads system operation data, and receives remote control commands; the display module 9 displays system parameters in real time, and the horn 8 emits an alarm signal in case of a fault.
