[0002] With the widespread use of smartphones, phone cases, as frequently used accessories, are experiencing a continuous rise in market demand. However, most phone cases currently on the market are made from non-biodegradable plastics such as polyvinyl chloride (PVC) and polypropylene. These materials decompose extremely slowly after being discarded, and long-term accumulation leads to "white pollution," causing serious damage to the ecological environment and increasing the environmental burden. At the same time, existing phone cases have relatively limited functions, mostly confined to basic protection. Although some phone cases have begun to add support functions, these are mostly fixed angles, unable to be flexibly adjusted, and difficult to adapt to diverse user scenarios. For example, when a user needs to watch videos on a high-speed train tray table, a fixed-angle support may not be able to accommodate the tray table's tilt.

[0003] In view of this, developing an environmentally friendly phone case back cover with a flexible folding structure and rich functionality has become a problem that the industry urgently needs to solve. Utility Model Content
