[0034] Shell structure: including main control board fixing plate 21, axial flow fan 24, fan fixing plate 20, and the overall shell 23 arranged around the fan. Also includes battery PACK protection box 18, fan fixing plate 20 around the design of air duct plastic paper and air duct baffle 19, and the overall shell 23 rear panel is provided with fan heat dissipation hole 8. The design of battery PACK protection box 18 makes the battery power system and other signal system separate, there will be no interference and other dangers;

[0035] The overall shell 23 front and rear panel is formed by laser cutting and bending machine bending processing, and a plurality of bending tools are spliced during bending to ensure that the bending interface forms a tear interface.

[0036] In use, first, the main control inverter circuit board is installed on the main control board fixing plate 21, ensuring that the circuit board is stable and correctly aligned. Then, the axial flow fan 24 is fixed on the fan fixing plate 20, and the axial flow fan 24 is located in front of the main control inverter board. The axial flow fan 24 arranged in this way is directly opposite the heat dissipation aluminum device installed on the main control board fixing plate 21, and adopts the cooling mode of air suction, which can effectively absorb the heat generated during the operation of the equipment.

[0037] In addition, by setting the air duct plastic paper and air duct baffle 19, the airflow generated by the fan can be guided to have directivity, thereby more efficiently cooling the main control inverter board.

[0038] Portable design: the front panel and the rear panel of the shell assembly 23 are each provided with a handle 1, facilitating carrying and moving.

[0039] Heat dissipation and display: the front panel of the shell assembly 23 is provided with four heat dissipation holes 3 on both sides, so as to improve the heat dissipation efficiency. The upper part and the lower part of the front panel are respectively provided with an LCD display screen 2 and an output plug-in port 6. A panel prompt lamp 4 and a control button 5 are sequentially arranged below the LCD display screen 2. The control button 5 is used for controlling the power supply circuit board. When pressed, the overall device is turned on. The surface of the control button 5 and the LCD display screen 2 is in the same plane as the surface of the first mounting portion.

[0040] Charging and protection: one side of the front panel of the shell assembly 23 is sequentially provided with a main control room safe button 9 and a photovoltaic charging port 10. The main control board safety button 9 is used to trip when a fault occurs, thereby protecting the main control board, and is pressed again to restore power. The photovoltaic charging port 10 is used to connect the photovoltaic panel to charge the device. The charging port uses Anderson large current terminals to improve the photovoltaic charging speed. The main control room safety button 10 is provided below the ground screw 11, which can hang the grounding wire at any position to ground the entire device. The lower part of the front panel is sequentially provided with three groups of air switches 12, a detachable wiring baffle 13 and two wire holes 14.

The device is provided with two wire holes 14, and a rubber tooth is bound on the wire hole 14 to place the worn wire. The detachable wiring baffle 13 can be detached and directly connected to the device to provide long-term use conditions. The photovoltaic charging switch 12 is provided on one side with a surge protector 26 to enhance the safety of the charging process.

[0041] Internal support structure: the inside of the front panel of the shell assembly 23 is provided with a main control room safe button support frame 15 corresponding to the position of the main control room safe button 9, and a photovoltaic charging switch fixing frame 17 corresponding to the position of the photovoltaic charging switch 12, so that the main control room safe button 9 and the photovoltaic charging switch 12 can be sunk below the outer plane of the device, avoiding some misoperations caused by collision or lifting process. Many switches and buttons on the commonly used devices are exposed outside the device size, which is easy to cause misoperation. In addition, an operating panel wiring frame 16 is also provided to bind the wires on the front and rear panels of the shell assembly 23 with electrical devices to the main control board and other parts along the shell assembly 23 inside in the same direction. When the device needs to be maintained, the panel can be turned around the wire curvature radius center as the axis to open the panel without unplugging the internal wires.

[0042] Detail design: the edges of the bottom plate 25 adopt R30 arc design, which can make the edges of the device not conspicuous, can achieve the purpose of protecting the device from external collision, and can also play the role of structural stability and not easy to deform. The processing method of the arc R30 adopts a special CR20 die steel to make a mold first, and then adds a gasket on the mold or around the mold to adjust the size structure according to the different use requirements and use positions.

[0043] Bottom structure design: the bottom plate 25 is provided below the battery PACK protection box 18, and the bottom plate reinforcing beam 22 is welded on the bottom plate 25 to bear the gravity of the battery PACK protection box 18 and also play the role of tensioning the arc R30 to prevent it from deforming. During welding, intermittent welding is adopted to ensure that the bottom plate does not deform and the stress intensity meets the design requirements. In addition, the upper end of the arc R30 on the bottom plate 25 is extended for a distance, and is pressed by a bending machine, so that the side panel of the shell assembly 23 can be more firmly inserted and fixed with the bottom plate and integrated to achieve the effect of dust and water prevention. Four universal brake casters 7 are installed below the bottom plate to provide good mobility and positioning stability.

[0044] Socket design: in order to overcome the problem caused by improper arrangement of the interface during use of the portable energy storage device, the charging interface and the discharging interface are distributed in different areas of the shell assembly 23 to ensure that they do not interfere with each other physically.
