The mobile phone has become an essential tool for people. People now often use their mobile phones to play games, read novels, watch videos, etc. In order to make the mobile phone more beautiful and have a certain drop-proof effect, people will install a mobile phone case for the mobile phone; the traditional mobile phone case has poor shock absorption performance, especially when the mobile phone falls sideways, it is easy to cause damage to the mobile phone. Moreover, as electronic products become more and more miniaturized and sophisticated, for smart phones, there are many sophisticated parts inside the smart phone. When the smart phone accidentally falls to the ground, its internal sophisticated parts are easily damaged, resulting in The mobile phone cannot be used normally; in order to reduce the probability of mobile phones being broken, air bags are added to existing mobile phone cases, so that when the mobile phone equipped with the mobile phone case falls sideways or collides with an object from the side, the air bags can contact the ground or the object, thereby reducing the damage to the mobile phone and improving the anti-fall effect of the mobile phone; however, the air bag structure design of the existing mobile phone case is poor, and the air bag is usually assembled on the mobile phone case in a sealed state. The sealed air bag is deformed by the user's touch during assembly, and the deformation is restored when the user releases the air bag, making it difficult for the air bag to be misaligned with the mobile phone case during assembly and positioning, thereby reducing the production efficiency of the product, making it inconvenient to operate, assembling troubles, poor practicality, and a small scope of application.
