Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0030] Combine the following Figures 1 to 4 , describing an embodiment of the utility model.

[0031] According to an embodiment of the utility model, on the one hand, an energy storage tool box is provided, comprising: a box body 1, a power generation structure 2, a rectifier-inverter structure 3, an energy storage unit 4, a power output port 5 and a power input port 6.

The power output port 5 is arranged at the outer wall of the box body 1, and the power output port 5 is electrically connected to the energy storage unit 4. The power input port 6 is arranged at the outer wall of the box body 1, and the power input port 6 is electrically connected to the rectifier-inverter structure 3.

[0032] The energy is converted into electrical energy through the power generation structure 2, and then the electrical energy is transmitted to the energy storage unit 4 for storage through the rectifier inverter structure 3. When it is necessary to power electric tools or other electrical components, the electrical energy of the energy storage unit 4 is output through the power output port 5. There is no need to ignite the construction machinery or use a starting battery for power supply, which improves the convenience of outdoor electricity use. Moreover, when the power generation structure 2 cannot be used and the energy storage unit 4 is low in power, other methods can be used to charge the energy storage unit 4 through the power input port 6 to ensure normal power supply of the energy storage unit 4.

[0033] It is worth noting that in the related art, the diesel engine of the construction machinery is operated and the on-board generator is used to supply power to the electrical components, which increases fuel consumption and is not environmentally friendly; or, when the engine is turned off, the starting battery of the construction machinery is used to supply power to the electrical components, which consumes the power of the starting battery for a long time, causing the voltage of the starting battery to be lower than the starting voltage of the diesel engine motor, affecting the starting of the construction machinery. In addition, when using the on-board generator or starting battery for power supply, it is necessary to lay wires, which makes the use of electricity more inconvenient.

[0034] The energy storage tool box of this embodiment is provided with an energy storage unit 4 in the box body 1, and the power generation structure 2 and the rectifier inverter structure 3 are used to power the energy storage unit 4.

Therefore, the energy storage unit 4 can be charged in a variety of ways to improve the reliability of the energy storage toolbox.

[0042] It is worth noting that in other alternative embodiments, the power generation structure 2 includes a wind power generation unit, which is connected to the outer wall of the box body 1.

The partition structure 7 is used to divide the inside of the box 1, so that the inside of the box 1 can be used in different partitions, which is more convenient to use.

[0044] It is worth mentioning that please refer to Figure 1 and Figure 4 , the tool, the rectifier inverter structure 3 and the energy storage unit 4 correspond to different cavity settings.

[0045] Of course, in other alternative embodiments, any two or three of the tool, the rectifier-inverter structure 3 and the energy storage unit 4 may share the same cavity.

[0046] In one embodiment, Figure 1 and Figure 4 As shown, at least one of the plurality of cavities is a heat dissipation air duct cavity 102, and a vent 105 is provided through the wall of the box body 1, and the vent 105 is connected to the heat dissipation air duct cavity 102.

[0047] Specifically, in this embodiment, if Figure 1 and Figure 4 As shown, the partition structure 7 includes a transverse partition 701 and a vertical partition 702, which are arranged vertically and crosswise to divide the interior of the box 1 into four cavities, which are arranged in two layers, and each layer has two cavities.

[0048] In one embodiment, Figure 1 and Figure 2 As shown, the box body 1 includes a main body 103 and a box cover 104. The main body 103 has an opening 1031, and the opening 1031 is at least connected to the tool accommodating space 101. The box cover 104 is detachably connected or movably connected to the main body 103 to open or close the opening 1031. By providing the box cover 104, the components inside the box body 1 can be protected while facilitating the taking and placing of tools.

[0049] Specifically, in this embodiment, if Figure 1 and Figure 2 As shown, the top of the main body 103 forms an opening 1031, and the box cover 104 is arranged corresponding to the top of the main body 103 and can be opened or closed. Further, the solar panel is arranged on the outer surface of the box cover 104, that is, the side of the box cover 104 away from the tool accommodating space 101.

[0050] Of course, in other alternative embodiments, the opening 1031 may be opened corresponding to other sides of the main body 103 , such as the front side or the rear side of the main body 103 .

[0054] When using the energy storage toolbox of this embodiment, in the presence of sunlight, the solar panel absorbs solar energy and converts it into electrical energy, and transmits the electrical energy to the energy storage unit 4 for storage through the rectifier inverter structure 3; when it is necessary to power the electrical components, the electrical components are electrically connected to the power output port 5, and the energy storage unit 4 is used to provide electrical energy to the electrical components. When the weather is long-term due to insufficient sunlight and the power of the energy storage unit 4 is lower than a predetermined value, the on-board generator or the mains interface is electrically connected to the power input port 6, and the electrical energy is transmitted to the energy storage unit 4 through the rectifier inverter structure 3 for energy replenishment.
