[0024] As Figure 1As shown, a small mobile energy storage device for emergency power supply includes a shell box 1, a chassis 2 and a moving assembly; the shell box 1 is provided with a containing space, the bottom of the shell box 1 is fixedly connected with the chassis 2, the chassis 2 is provided below the moving assembly for driving the chassis 2 to move, the shell box 1 is provided with a front panel and a rear panel 5, and the containing space is provided with an energy storage inverter unit assembly 7.

[0025] As shown in Figure 6 The energy storage inverter unit assembly 7 includes a battery module BAT1, a power distribution unit PDU, a DC-DC converter DCDC, a DC bus DC BUS, a switching power supply module SMPS, maximum power point tracking modules MPPT1 and MPPT2, an adapter module ADAPTER1, and a DC-AC converter DCAC.

[0026] The battery module BAT1 can be an aluminum shell lithium iron phosphate battery pack, and the aluminum shell lithium iron phosphate battery pack has a capacity of 30kWh, and the converter has a pure sine wave power output of 12kW.

[0027] The battery module BAT1 is connected to the DC bus DC BUS through the power distribution unit PDU and the DC-DC converter DCDC, the DC bus DC BUS is used as a common transmission path for DC power in the system, and is connected with each DC module. The DC bus DC BUS is connected with the switching power supply module SMPS, and the switching power supply module SMPS is connected with the strong light LED lighting, the wireless charging module and the USB charging interface. The DC bus DC BUS is connected with the maximum power point tracking modules MPPT1 and MPPT2, the maximum power point tracking modules MPPT1 and MPPT2 are respectively connected with PV1 and PV2 photovoltaic panels, and are used for adjusting the working point in real time to make the photovoltaic panel output maximum power. The switching power supply module SMPS is also connected with the adapter module ADAPTER1 and the DC-AC converter DCAC.

[0028] By connecting to the DC bus DC BUS through the power distribution unit PDU and the DC-DC converter DCDC, the battery energy can be effectively managed and distributed. In this way, the system can flexibly adjust the energy transmission between different modules according to actual needs, and the overall efficiency of the system is improved.

[0029] The energy storage inverter unit assembly 7 is connected with the interfaces on the front panel and the rear panel 5 through cables to realize input, output and function expansion of electric energy.

[0030] As shown in Figure 3 The front panel is provided with a waterproof recessed five-hole industrial socket 63, a photovoltaic charging interface 64, a waterproof USB charging interface 65 and a single-phase three-core 63A industrial aviation plug 66.

[0031] The single-phase three-core 63A industrial aviation socket 66 can meet the high-power charging and discharging needs of outdoor converters. Two waterproof concealed five-hole industrial sockets 63 are provided to provide power supply connection for regular loads and for external power strip use. The photovoltaic charging interface 64 can meet the online charging needs under good outdoor lighting conditions. LED lights are also set on the front panel, with dual 10W LED lights to meet the needs of emergency lighting and night driving.

[0032] The waterproof USB charging port 65 allows users to charge electronic devices directly via the USB interface.

[0033] The front panel is also equipped with monitoring and display components, including a digital display of output voltage, current and frequency 67 and a device power supply output accumulator 68, which are used to monitor output parameters and record power supply time in real time.

[0034] Voltage, current, and frequency sensors are installed in the energy storage inverter unit component 7. These sensors are responsible for collecting the output voltage, current, and operating frequency of the energy storage system in real time. The collected data is filtered and amplified by a signal conditioning circuit to ensure accurate transmission to subsequent processing units. The processed electrical signal is sent to a microprocessor or dedicated measurement chip for further analysis and calculation. Here, the microprocessor calculates the actual voltage, current, and frequency values ​​based on the received data. The calculated results are displayed to the user on a screen. The digital display 67 clearly shows the current output voltage, current, and frequency, allowing the user to intuitively understand the device's operating status.

[0035] The device's power supply output accumulator timer 68 is implemented based on a precise timing module. This module can be a hardware timer or a software timer for an embedded system. When the energy storage inverter unit component 7 starts supplying power, the timing module is activated and begins timing. Once an output stop is detected, timing pauses and this time is accumulated into the total power supply time. The accumulated time information is stored in a non-volatile memory (such as EEPROM or Flash), so that the recorded power supply time can be saved even after the device is powered off. Each time the device restarts, it reads the previous data from the memory and continues to accumulate new power supply time based on this.

[0036] like Figure 2 As shown, the rear panel 5 is provided with an integrated triangular AC socket 51 for charging the energy storage component and an integrated triangular AC socket 52 for charging the electric mobile chassis.

[0037] The chassis 2 includes a battery assembly BAT2, a driver module DRIVER, and a motor module MOTOR. The driver module DRIVER and the motor module MOTOR are used for driving control of the moving assembly. The battery assembly BAT2 is also connected to a mobile adapter module ADAPTER2, which is used to convert direct current into alternating current to power devices that require alternating current.

[0038] The battery assembly has a battery capacity of 48V 20Ah and a motor power of 1kW. The battery assembly is connected to an integrated pin-shaped AC outlet 52 for charging the electric moving chassis. When the moving assembly needs to be charged, first connect the AC 220V charging cable to the integrated pin-shaped AC outlet 52 for charging the electric moving chassis. The charging mode selection switch 53 can also be set to mode two, and the AC 220V output by the energy storage inverter unit assembly 7 can be used to charge the moving assembly. This is an emergency self-charging requirement when the power is insufficient in the driving diagram.

[0039] The integrated pin-shaped AC outlet 51 for charging the energy storage assembly allows users to charge the energy storage assembly by connecting to the mains or other external power sources such as generators. This allows the device to quickly replenish power when the power is depleted, ensuring that it can be used at any time when needed.

[0040] The upper part of the shell box 1 is provided with a mobile phone wireless charging seat 11 to meet the charging needs of mobile phones and wireless charging wearable products. The side of the shell box 1 is provided with a side driving camera 12. The shell box 1 is also provided with a front driving camera 61 and a rear driving camera 55. This realizes the 360-degree panoramic image function and is suitable for remote control or automatic driving scenarios. The shell box 1 is surrounded by cameras distributed at different positions, which can realize full-range visual coverage and form a 360-degree panoramic image. This is very helpful for navigation and operation in complex environments and can effectively avoid blind spots and improve safety.

[0041] As shown in Figure 4 The lower part of the shell box 1 is provided with a lower air inlet grille 13, and the top is provided with an upper air outlet grille 56, which is in communication with the internal heat dissipation air duct 8 to form an air circulation path. Through the design of bottom air inlet and top air outlet, cold air enters from the bottom and is discharged from the upper side after absorbing the heat generated by the internal components. This way can effectively reduce the internal temperature of the device and protect sensitive electronic components from overheating damage.

[0042] The moving assembly is a wheeled moving mechanism, which comprises a driving wheel 31 and a steering wheel 32 mounted on a driving support installed on the chassis 2, and a control handle 4 is arranged on the steering wheel 32, and a handle display control screen 41 is arranged on the control handle 4 for operation and monitoring of the running state of the energy storage device. The presence of the control handle 4 allows the user to conveniently control the direction and speed of the device.

[0043] An electric control system is arranged on the battery assembly in the chassis 2 to drive the driving wheel 31 to move and the steering wheel 32 to steer.

[0044] As shown in Figure 5 In order to improve the terrain adaptability, the moving assembly is a tracked moving mechanism, which comprises a tracked driving wheel 33, a load wheel 34, and a tracked chassis electric control box 36; the tracked driving wheel 33 and the load wheel 34 are installed on the chassis 2, a rubber track 35 is arranged between the tracked driving wheel 33 and the load wheel 34, and the tracked chassis electric control box 36 is installed on the chassis 2 for controlling the operation of the tracked driving wheel 33.

[0045] The tracked driving wheel 33 is driven to operate by the battery assembly in the chassis 2 to move the track.

[0046] An aerosol fire extinguishing module 9 is arranged in the accommodation space for automatically starting fire extinguishing in case of emergency such as electrical fire. The aerosol fire extinguishing module 9 is electrically connected with a system alarm audible and visual alarm 54 and an emergency stop button 62.

[0047] When a fire sign (such as temperature reaching 175±15℃) is detected, an automatic starting mechanism is triggered, the aerosol fire extinguishing module 9 releases fire extinguishing agent for rapid fire extinguishing, the system alarm audible and visual alarm 54 immediately issues a sound and visual signal to warn the operator of potential danger, and the emergency stop button 62 is directly connected to the main control circuit and immediately cuts off all power supply and stops all electrical activities when pressed.

[0048] The aerosol fire extinguishing module is a high-efficiency automatic fire extinguishing device, which uses aerosol fire extinguishing agent to automatically release to suppress fire when fire is detected. Specifically, a 100g aerosol fire extinguishing module with a fire extinguishing density of 100g / m³ for lithium ion battery is integrated in the accommodation space.

[0049] It should be noted that the socket, interface, camera, control system, aerosol fire extinguishing module, etc. of the embodiment are all general standard parts or components known to those skilled in the art, and their structure and principle can be known by those skilled in the art through technical manuals or through conventional experimental methods.
