[0041] Please refer to Figures 1-4. This embodiment provides an electric forklift charging box 100, which includes a mounting base 110, a main body 120, an inspection door 130, and an electrical control box 140.

[0042] The main enclosure 120 contains a battery compartment 101 and an electrical compartment 102; the access door 130 is rotatably connected to the main enclosure 120; the electrical control box 140 is located in the electrical compartment 102, in the area of ​​the electrical compartment 102 directly opposite the access door 130.

[0043] Please refer to Figures 1-4. The working principle of the electric forklift charging box 100 is as follows:

[0044] Firstly, the electric forklift charging box 100 is used in the electric forklift mobile charging device 200. Its purpose is to accommodate and install the battery, electrical and control components of the electric forklift mobile charging device 200 as needed. The electric forklift charging box 100 is used in the electric forklift mobile charging device 200. Its structure is simple, it is easy to use, and it is convenient to maintain or repair it in the future.

[0045] Specifically, the electric forklift charging box 100 includes a mounting base 110, a main body 120, an inspection door 130, and an electrical control box 140.

[0046] The main housing 120 contains a battery compartment 101 and an electrical compartment 102, which are used to install batteries and electrical components, respectively. An inspection door 130 is rotatably connected to the main housing 120. An electrical control box 140 is located within the electrical compartment 102, directly opposite the inspection door 130. This allows the relevant control components of the electric forklift mobile charging device 200 to be integrated into the electrical control box 140. Since the electrical control box 140 faces the inspection door 130, maintenance and repair of the control components within the electrical control box 140 can be performed by opening the inspection door 130, thereby improving ease of use, reducing the difficulty of maintenance and repair work, and increasing the efficiency of maintenance and repair work.

[0047] It should also be noted that the electric forklift charging box 100 can be equipped with relevant batteries and electrical components according to usage requirements. That is, the specifications and models of the batteries and electrical components inside can be adapted to usage requirements. However, as mentioned above, it has a battery compartment 101 and an electrical compartment 102 inside, and is equipped with an electrical control box 140. Therefore, the internal structural layout can be optimized in this way, so that the batteries, electrical components and control components are installed separately from each other, thereby improving its safety in use.

[0048] Further referring to Figures 1-4, in this embodiment, to facilitate the installation of related components inside and the installation and maintenance of the internal batteries and electrical components, a movable door 150 is provided on the side of the main housing 120 opposite to the access door 130, and is rotatably connected to the main housing 120. Thus, during use, the batteries installed in the battery compartment 101 and the electrical components installed in the electrical compartment 102 can be installed and maintained through the movable door 150, while the components in the control box 140 can be maintained through the access door 130, thereby facilitating related inspection and maintenance.

[0049] It should be noted that, compared with the prior art where control components are distributed inside the device, this embodiment integrates the relevant control components into the electrical control box 140. This allows for convenient inspection and maintenance. The relevant control components include components such as circuit breakers, relays, and fuses, and the specific types of these components can be adjusted according to usage requirements.

[0050] In this embodiment, the main housing 120 is configured as follows: the main housing 120 includes a main frame 121, a main partition 122, and multiple side plates 123; the main frame 121 is connected to the mounting base 110; the sides of the main frame 121 other than the maintenance door 130 and the movable door 150 are connected to the side plates 123; the main partition 122 is connected to the main frame 121 to divide the inner cavity of the main housing 120 into a battery compartment 101 and an electrical compartment 102; wherein the maintenance door 130 and the movable door 150 are rotatably connected to the main frame 121.

[0051] The inspection door 130, the movable door 150, and the side panel 123 are all connected to the main frame 121 to form an inner cavity, and the main frame 121 improves the overall structural strength. The main partition 122 divides the inner cavity into a battery compartment 101 and an electrical compartment 102, thereby optimizing the internal layout and separating the battery and other components.

[0052] To improve installation stability, the electrical control box 140 can be connected to one or both of the main partition 122 and the main frame 121 during installation. In this embodiment, multiple connectors are distributed at both ends of the electrical control box 140, and these connectors are connected to the main frame 121 and the main partition 122 respectively to improve its stability.

[0053] Furthermore, referring to Figures 1-4, based on the above structure, to improve the overall heat dissipation performance of the enclosure, at least one ventilation opening 124 communicating with the electrical compartment 102 is provided on the two side plates 123 located on opposite sides of the main frame 121. Moreover, the ventilation openings 124 are provided on both opposite side plates 123 to achieve convection cooling. The ventilation openings 124 are positioned corresponding to the electrical compartment 102 because the heat dissipation components for cooling the battery compartment 101 are all installed inside the electrical compartment 102, thereby improving the working efficiency of the heat dissipation components.

[0054] Based on the above structure, referring to Figures 1-5, since multiple electrical components need to be installed inside the electric forklift charging box 100 to create the electric forklift mobile charging device 200, a sub-partition 160 is provided inside the electrical compartment 102 to partition the multiple electrical components for separate installation. The sub-partition 160 divides the electrical compartment 102 into a first compartment 103 and a second compartment 104, and one end of the sub-partition 160 is separated from the access door 130, thus forming a space for installing the electrical control box 140. This allows different electrical components to be installed in the first compartment 103 and the second compartment 104 respectively, thereby optimizing the internal structure, improving space utilization, and facilitating future maintenance.

[0055] In accordance with the first compartment 103 and the second compartment 104 mentioned above, in order to meet the heat dissipation requirements of the components in the first compartment 103 and the second compartment 104, the two side plates 123 located on opposite sides of the main frame 121 are provided with a first ventilation port 125 and a second ventilation port 126. The first ventilation port 125 is connected to the first compartment 103, and the second ventilation port 126 is connected to the second compartment 104.

[0056] Based on the above, please refer to Figures 1-8. This embodiment also provides an electric forklift mobile charging device 200. The electric forklift mobile charging device 200 includes a battery unit 210, an electrical component 220, a control component, and the aforementioned electric forklift charging box 100. The battery unit 210 is installed in the battery compartment 101, the electrical component 220 is installed in the electrical compartment 102, and the control component is installed in the electrical control box 140.

[0057] The electric forklift mobile charging device 200, by adopting the aforementioned electric forklift charging box 100, allows for the partitioned installation of its battery unit 210 and electrical components 220, thereby facilitating the enclosed installation of the battery and improving battery safety. Furthermore, by installing the electrical components 220 inside the electrical compartment 102 and the control components inside the electrical control box 140, the relevant control components inside can be inspected and maintained through the inspection door 130, thereby improving the efficiency of maintenance and repair during later use.

[0058] Furthermore, a sub-partition 160 is provided within the electrical compartment 102, dividing the electrical compartment 102 into a first compartment 103 and a second compartment 104. When configuring the electrical components 220, taking the electrical components 220 including a heat sink 221, a high-voltage box 222, a DC control box 223, an energy storage converter 224, and a DC converter 225 as an example, the heat sink 221, the high-voltage box 222, and the DC control box 223 can all be installed in the first compartment 103, and the energy storage converter 224 and the DC converter 225 can all be installed in the second compartment 104. In this way, the various components can be partitioned to optimize their layout, facilitating future maintenance and repair. Moreover, to improve the internal heat dissipation and ventilation efficiency, a first ventilation opening 125 is provided on the side of the main enclosure 120, directly facing the heat sink 221.

[0059] It should be noted that the heat sink 221, high voltage box 222, DC control box 223, energy storage converter 224, DC converter 225 and control components in the electrical control box 140 mentioned above can all adopt existing technologies. Therefore, their specific structural principles will not be described in detail here.

[0060] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
