The extension portion 194 and the bottom surface 162 of the cover plate 16 are connected by dispensing glue. There is a gap between the extension 194 and the top surface 144 of the display screen 14, which can provide a buffer space when the electronic device 100 encounters a collision or shock; similarly, the bottom surface 146 of the display screen 14 is disposed on the bottom wall 122 of the bracket 12, and the display The bottom surface 146 of the screen 14 is combined with the bottom wall 122 by gluing. Specifically, a layer of foam glue or double-sided tape can be placed between the bottom surface 146 of the display screen 14 and the bottom wall 122 of the bracket 12 as required. The structure is designed to provide a buffer space when the electronic device 100 encounters a collision object, so as to protect the display screen 14 and prolong the service life of the electronic device 100 .
