Smartphone stand and charging pencil case

Pencil case with a rotating auxiliary storage body that doubles as a smartphone stand and charger

This technology features a pencil case with an auxiliary storage body hinged to a main body that houses a battery. When opened, the resulting ledge allows a smartphone to be propped up and charged via the built-in battery. Pairs of magnets on both sides of the hinge maintain the closed position, while the remaining magnetic force allows the case to attach to metal surfaces.

While existing multi-purpose phone pouches could hold a power bank, they were rarely used because most users prefer slim cases. In particular, students who spend long hours watching online lectures or videos lacked a convenient way to prop up their devices while charging them simultaneously.

This technology integrates pencil storage, a smartphone stand, and power bank charging into a single case, using anti-slip protrusions to securely support the phone. It can be applied to student stationery and mobile learning accessories, allowing users to watch lectures and charge their devices on their desks without a separate stand.

Key Features:

• A main storage body for the battery and an auxiliary storage body rotatably coupled via a hinge to selectively form a ledge
• A mounting structure where the smartphone rests on the main body and leans against the auxiliary body while connected to the battery
• First and second pairs of magnetic units formed on both sides of the hinge that exert attractive forces
• An attachment structure where the pencil case remains adhered to magnetic surfaces using the remaining magnetic force when the pairs are engaged
