[0025] like Figure 1-3 As shown, the energy storage device 1 also includes a frame 120 fixedly installed along the outer edge of the front end and the bottom end of the energy storage device 1. One end of the frame 120 is shown as a double L-shape intersecting at the end through a crossbeam 121, and the other end is shown as a U-shape, wherein the foot pads 5 are respectively fixed on both sides of the front end of the bottom of the energy storage device 1, and the wheels 4 penetrating through the rotating shaft 3 and arranged at both ends of the other side of the bottom of the energy storage device 1 are matched to create a distance between the energy storage device 1 and the ground, which can not only support the energy storage device 1 but also prevent the energy storage device 1 from being worn due to friction with the ground.

[0026] Continue reading Figure 1-3 In this embodiment, the handle 130 is installed on the front end frame 120 of the energy storage device 1 through a U-shaped connecting plate 131 fixedly provided at the end and is fixed with a pin 132 to realize rotational connection.

After reaching the target position, the energy storage device 1 is put down and supported by the wheels 4 and foot pads 5 arranged symmetrically around the center of the energy storage device 1. Then, the handle 130 is pressed into the elastic buckle 122 to complete the placement.

[0027] like Figure 7 As shown, a second power input interface 140, a switch 150 and a short-circuit protector 160 are arranged at the rear end of the energy storage device 1.

It can charge both external electrical appliances and the energy storage device 1 itself, which is convenient for repeated use. Among them, the power output interface 6 of the device is set to four currents of 20v and 30v respectively, which is convenient for users to charge products of different specifications. At the same time, by arranging the power output interface 6 and the first power input interface 110 and the second power input interface 140 in different positions, it is convenient for users to distinguish and use them. The short-circuit protector 160 is arranged to cut off and connect the load circuit when a circuit fault occurs, and to cut off the fault circuit to prevent the accident from expanding and ensure safe operation. The switch 150 is arranged so that the user can manually control the start and stop of the device.

[0028] like Figure 1-4As shown, in this embodiment, arc-shaped or semicircular baffles 10 protruding outward are arranged in an array at the front and rear ends of the energy storage device 1, and the baffles 10 have an unsealed bottom, wherein the baffles 10 are arranged to be arc-shaped or semicircular protruding outward. When it rains, rainwater can slide down from the outside of the energy storage device 1 along the outer arc structure of the baffle 10, thereby preventing rainwater from entering the energy storage device 1 and damaging the internal inverter board 11 and battery module 12 and other electronic components. At the same time, an opening is set at the bottom of the baffle 10 to facilitate the first cooling fan 1230 to blow heat out of the energy storage device 1 to reduce the heat in the energy storage device 1.

[0029] As a further explanation, the inverter board 11 also includes some inverter components including capacitor heat sinks and voltage regulators. The capacitors are arranged at the bottom of the inverter board 11; the heat sinks are arranged on both sides of the inverter board 11; the voltage regulator is arranged at the bottom of the inverter board 11; wherein the capacitors, heat sinks and voltage regulators are all electrically connected to the inverter board 11, which is not shown in the conventional prior art figure.

[0030] like Figure 4 As shown, in this embodiment, the power module 12 includes a battery pack 1210; a partition 1220 fixedly connected to the top of the battery pack 1210 and provided with a connection groove array, two or more first cooling fans 1230 respectively installed at both ends of the top of the partition 1220 and arranged parallel to each other, and an inverter board 11 arranged on the top of the partition 1220 and located between the first cooling fans 1230, the partition 1220 is installed inside the energy storage device 1 and is electrically connected to the battery pack 1210 and is arranged above the battery pack 1210 to isolate the inverter board 11 from the battery pack 1210, avoiding Without affecting the installation of the battery pack 1210, the inverter board 11 is fixed on the partition 1220 and electrically connected to the battery pack 1210, so that the energy storage device 1 can be used independently, and has multiple functions such as AC discharge, DC discharge, PD / USB discharge, AC charging, solar charging, and DC generator charging, which effectively solves the problem of insufficient power of ordinary energy storage products outdoors and users' power anxiety. At the same time, the pure sinusoidal AC power output by the energy storage device 1 is more stable and has lower noise than the AC power output by AC generators on the market, and is more conducive to the use of large loads.

[0031] There are gaps between adjacent electronic components on the inverter board 11 to form a heat dissipation duct to facilitate the wind flow of the first heat dissipation fan 1230 , thereby avoiding affecting the heat dissipation effect of the first heat dissipation fan 1230 .

[0032] Continue reading Figure 4The first cooling fan 1230 and the baffle 10 are arranged parallel to each other and located on the same axis, and the air outlet direction of the first cooling fan 1230 is consistent and electrically connected to the inverter board 11. By symmetrically arranging an even number of first cooling fans 1230 at both ends of the inverter board 11 and setting the air outlet directions of the first cooling fans 1230 to be consistent in the same direction, the first cooling fan 1230 can blow the heat generated by the inverter board 11 to the unsealed parts of the baffles 10 on both sides through the cooling air duct to quickly discharge the heat out of the energy storage device 1.

[0033] like Figure 1 and Figure 5 As shown, the generator 2 includes a second cooling fan 210 arranged inside the shell; a heat dissipation slot 211 on the same side as the second cooling fan 210 and a small heat dissipation slot 212 on the other side, and a connected grid 213 is arranged on the heat dissipation slot. By installing the second cooling fan 210 in the shell of the generator 2 and matching the positions of the second cooling fan 210 and the heat dissipation slot 211; the second cooling fan 210 can discharge the heat generated by the generator 2 during charging and operation from the small heat dissipation slot 212 to the outside of the body, thereby reducing the heat in the shell of the generator 2, and the setting of the grid 213 can reduce the entry of dust or rainwater and extend the service life of the product.

[0034] like Figure 6 As shown, as a further explanation, the generator 2 is a DC generator and can only be used in conjunction with the energy storage device 1. When the communication protocol is set and the generator 2 and the energy storage device 1 are connected through the connecting line 9, the entire product has the function of automatically starting the generator 2 to charge. When the remaining power of the energy storage device 1 is less than 20%, the energy storage device 1 will automatically send a command to start the generator 2. The generator 2 will automatically start and the energy storage device 1 will convert the DC power of the battery pack 1210 into a fixed-frequency and fixed-voltage or frequency-modulated and voltage-regulated AC power through the inverter board 11. When the generator 2 is accidentally turned off or has other problems during operation, the generator 2 will send a fault code to the energy storage device 1, and the corresponding fault code will be displayed on the display screen 7 of the energy storage device 1. When the remaining power of the energy storage device 1 is charged to more than 90%, the energy storage device 1 will send a stop command, and the generator 2 will automatically stop running accordingly. It is environmentally friendly, safe and reliable. Through the combination of the energy storage device 1 and the generator 2, the advantages of the two products are combined to effectively solve the problems of poor endurance of energy storage products on the market, poor generator output voltage stability, high equipment damage rate, high fuel consumption and high noise.
