Foldable portable writing tablets, due to their ease of carrying and flexible use, are gradually becoming a focus of market attention, and technological innovation in this area is crucial for improving user experience.
[0003] Most writing tablets on the market today use a one-piece fixed structure, mainly consisting of a rigid board and a frame to form the writing surface. These writing tablets usually rely on simple clips or magnetic devices to hold the writing paper in place, lacking a foldable design in their mechanical structure. Their working principle is to provide a stable writing support surface through the rigid board, and writing is done by directly operating the writing instrument on the board surface. The overall structure and usage method are relatively traditional and simple.
[0004] However, traditional one-piece fixed writing tablets are bulky due to their difficulty in folding. They are difficult to fit into common storage spaces such as backpacks and briefcases, causing significant inconvenience for users when traveling. Especially in office and study settings that require frequent movement, this non-foldable design severely limits the tablet's usability and fails to meet users' urgent need for portability.
