[0019] Please refer to Figures 1-3 , an embodiment provided by the present utility model: a lightweight plate structure for a tablet computer support sleeve, including a lower cover 1. A foam positioning layer 2 is fixedly bonded to the upper surface of the lower cover 1 by glue. A foam positioning cavity 3 is formed in the central area of the foam positioning layer 2. A PMI foam 4 is filled inside the foam positioning cavity 3. By providing the foam positioning cavity 3 in the foam positioning layer 2, the foam positioning cavity 3 can facilitate the positioning work of the PMI foam 4 during assembly, thereby having the use effect of assembly positioning, improving the overall structural use effect and installation efficiency of the present utility model;

[0020] And the present utility model arranges the PMI foam 4 inside the plate body. The PMI foam is a polymethacrylimide foam, abbreviated as PMI foam, which is a new type of polymer structural foam material. The PMI foam has the characteristics of light weight, high strength, high and low temperature resistance, etc. It has a 100% closed-cell structure, and this structure endows the PMI foam with excellent structural stability and mechanical properties;
