Problems solved by technology

[0002] As a commonly used communication tool, mobile phones have become an indispensable part of people's lives. With the popularity of smart phones, mobile phones are more and more widely used in daily life, and smart phones are highly integrated as a technology. This poses a huge challenge to the protection of mobile phones. When the mobile phone is impacted, the damage to the circuit board is particularly large. It is possible that the mobile phone may be irreparable during an inadvertent collision. Due to the advantages of low cost and other advantages, it has been widely developed in the field of mobile phone protective cases, but the existing plastic structure of mobile phone cases is low in strength, and it is prone to bending when the mobile phone is dropped or impacted, and cannot provide good protection for the internal components of the mobile phone. , and its own heat resistance and aging resistance are poor, the pressure is reduced at higher temperatures, the pressure bearing capacity is low, and the protective effect on mobile phones cannot meet the needs
