[0029] Compared with the prior art, the high-voltage box installation structure for energy storage provided in this embodiment is provided with a cabinet body 1, and multiple installation compartments are arranged inside the cabinet body 1 along the length direction of the cabinet body 1. Multiple support frames 4 are arranged inside the installation compartments, and multiple support frames 4 are arranged at intervals along the vertical direction to form installation positions for placing the high-voltage box 2 or the battery box 3. In this application, by designing the high-voltage box 2 to be a structure of the same size as the battery box 3, and by arranging multiple installation positions for installing the high-voltage box 2 or the battery box 3 inside the cabinet body 1, the installation positions of the high-voltage box 2 and the battery box 3 can be freely adjusted according to the needs of the on-site circuit or use, and the high-voltage box 2 is limited and fixed on the support frame 4 by the limiting component 5 and the fixing component. The structure is simple, and it is convenient for the free installation of the high-voltage box 2 and the layout of the entire energy storage cabinet.

[0030] Specifically, in this embodiment, when installing the high-voltage box 2, one end of the slide rail 41 slides into the installation position, and the installation position of the high-voltage box 2 is limited by the limiting component 5, and the high-voltage box 2 is fixed inside the installation position by the fixing component.

[0031] In some embodiments, the slide rail 41 may be Figure 2 、 Figure 3 See also Figure 2 、 Figure 3 The side of the slide rail 41 close to the inner wall of the installation bin is bent upward and provided with a first connecting plate 42 for fixing to the inner wall of the installation bin. The side of the slide rail 41 away from the inner wall of the installation bin is bent downward and provided with a second connecting plate 43 for fixing to the inner wall of the installation bin. The support frame 4 is formed as a whole by bending a steel plate. A first connecting plate 42 is bent upward on one side of the slide rail 41. A support plate is also connected between the slide rail 41 and the second connecting plate 43. The support plate is bent downward and tilted in the direction close to the inner wall of the installation bin.

In addition, the support plate is located below the slide rail 41 to enhance the support strength of the slide rail 41.

[0032] In some embodiments, the slide rail 41 may be Figure 2 、 Figure 3 See also Figure 2 、 Figure 3A guide plate 44 is bent on the second connecting plate 43 and is arranged parallel to and spaced apart from the slide rail 41.
