Description

Technical Field

[0001] This utility model relates to the field of portable electronic devices, and in particular to a charging device with storage function. Background Technology

[0002] The charging and data storage needs of portable electronic devices play a crucial role in modern life. With the increasing power of smartphones, especially the widespread use of video recording functions, users' reliance on device battery life and storage capacity has significantly increased. Research in this area is not only about improving user experience but also directly affects the practicality of mobile devices in educational, entertainment, and professional scenarios. However, current solutions often struggle to balance efficient charging and large-capacity data storage in a single device. Most existing power banks focus solely on power supply, neglecting the need for data expansion; while external storage devices typically lack power management capabilities, forcing users to carry multiple devices, increasing portability burdens and technical complexity.

[0003] The limitations of existing methods lie in the fact that the separation of charging and storage functions results in low device integration, failing to meet the dual power and storage requirements of smartphones during extended video recording. While common power banks on the market can power phones through simple voltage output, they lack protocol support for communication with phones, making it difficult to dynamically adapt to charging needs. Meanwhile, storage expansion devices typically require independent power supplies or additional interfaces, limiting their convenience in mobile scenarios. These shortcomings expose the inadequacy of current technology in multi-functional integration.

[0004] The core challenge lies in achieving efficient coordination between power management and data storage within a limited space. Specifically, the dynamic adaptability of power management, seamless access to data storage, and the control coordination between the two are key technical factors. Due to the lack of an effective protocol interaction mechanism, charging devices struggle to adjust their output voltage according to the phone's needs; the integration of storage functions is limited by the synchronization of data transmission and power management; furthermore, insufficiently precise logic design of the control unit can lead to system inefficiency or functional conflicts. These unresolved technical factors directly result in the unique challenge of devices being unable to simultaneously provide stable power and sufficient storage during long-duration video recording scenarios.

[0005] Therefore, designing a circuit architecture that enables dynamic management of battery charging and discharging, as well as seamless integration of storage functions, while establishing a power and data connection with the mobile phone, is the key issue of this research. Solving this problem will directly drive performance breakthroughs in portable devices across various application scenarios. Utility Model Content
