Immersive crystal ball 3D visual projection device

An immersive crystal ball 3D visual projection device, for displaying digital images, comprising:

• a hemisphere body serving as a projection image carrier, featuring a mounting surface and an outer spherical surface;
• a mounting base with a hemispherical hollow shell structure, connecting with the hemisphere body to form a complete sphere;
• wherein the mounting base comprises a mounting cavity housing a display screen and a control unit, with the display screen's viewing surface facing the mounting surface to project images within the hemisphere body, enabling external observers to view the projected images through the outer spherical surface;
• and
• the control unit comprises a display control board and a power control board, the display control board is electrically connected to the display screen to transmit image signals to it;
• the power control board is connected to a battery and is electrically linked to the display control board for power distribution and information exchange;
• the power control board manages battery power allocation and controls charge/discharge logic.
