Background technique

At present, mobile phones, pads and other mobile terminals fall during use, mostly from the hands, backpacks or tables, the height is about 0.8m ~ 1.2m. The experimental results show that the existing mobile terminal can only resist the drop from 0.7m high, and can not meet the demand of most falling scenes. Therefore, how to improve the anti-fall performance of mobile terminals is the key to the reliability research of mobile terminals. Since the most vulnerable part of the mobile terminal is the touch screen display module, how to protect the touch screen display module is the key to improving the anti-drop performance of the mobile terminal.

In order to protect the touch display module, an example of the present invention is as shown in FIG. 1 . Referring to FIG. 1 , the touch display module 01 , the front housing 02 and the rear housing are included. The touch display module 01 is embedded in the front casing 02, and the rear casing 03 is connected to the back of the front casing 02. The front casing 02 is made of a plastic material, and the plastic material can generate a certain degree of elastic deformation. Therefore, when the mobile terminal is dropped, the mobile terminal is in contact with the ground, and a buffer belt of a certain width is formed between the touch display module 01 and the front casing 02, and between the front casing 02 and the rear casing 03. The buffer belt can prolong the impact time, reduce the acceleration change, and reduce the impact force between the touch screen display module 01 and the front housing 02, between the front housing 02 and the rear housing 03, thereby reducing The impact force acting on the touch display module 01 protects the touch display module 01 to a certain extent.

However, since the front casing 02 mainly plays a supporting role in the mobile terminal, the hardness of the material cannot be greatly reduced, and the elastic deformation that can be generated is small, so the impact resistance effect is limited, and the protective effect is poor.
