With this structure, the electronic device adopting the above-mentioned anti-drop protection structure has a good protection effect on the display screen 3, and the risk of screen breakage is small.

The electronic device provided in the embodiment of the present application is subjected to a finite element simulation analysis test with the existing electronic device, and the test is to test the collision between the corner of the electronic device and the ground. Wherein, the positions of the four corners of the inner plate body 1 of the conventional electronic device are not provided with the protrusions 11 , that is, the outer plastic frame 2 is evenly covered on the inner plate body 1 . The broken screen risk test is carried out at different drop angles, including the following four schemes, scheme 1: the angle between the electronic equipment and the horizontal plane is 80°; scheme 2: the angle between the electronic equipment and the horizontal plane 85°; Option 3: The electronic device is perpendicular to the horizontal plane; Option 4: The angle between the electronic device and the horizontal plane is 100°.

After testing, when the electronic device provided in the embodiment of the present application and the display screen 3 of the existing electronic device both use TP (Touch Panel, touch screen) glass, the maximum strain of the display screen 3 of the existing electronic device is 9.5‰, There is a greater risk of broken screen. The display screen 3 of the electronic device provided in the embodiment of the present application uses TP glass and LCM (Liquid Crystal Module, liquid crystal display module) glass respectively to test the results as shown in the following table.

Option One Option II third solution Option 4 TP glass strain ‰ 2.3 4.7 3.1 1.6 LCM glass strain ‰ 1.5 1.4 1.1 1.4

It can be seen from the above comparative analysis that:

(1) When the same display screen 3 is used for testing, the degree of strain of the display screen 3 of the electronic device provided by the embodiment of the present application is obviously smaller than that of the display screen 3 of the existing electronic device, indicating that the embodiment of the present application is adopted. The electronic device provided with the anti-drop protection structure has a good screen protection effect, and the risk of broken screen is obviously reduced.

(2) When different display screens 3 are used for testing, the strain degree of the display screen 3 using LCM glass is obviously smaller than that of the display screen 3 using TP glass.

The above descriptions are only optional embodiments of the present application, and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection of the present application. within the range.
