Description

Technical Field

[0001] The present invention relates to the field of portable electronic devices, and in particular to a charging device with a storage function. Background Art

[0002] The need for charging and data storage of portable electronic devices plays a vital 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 increased significantly. Research in this field is not only related to improving user experience, but also directly affects the practicality of mobile devices in education, entertainment, and professional scenarios. However, current solutions often find it difficult to combine efficient charging and large-capacity data storage in a single device. Most existing power banks focus only on power supply and ignore the need for data expansion; external storage devices usually lack power management functions, resulting in users having to carry multiple devices, increasing the burden of portability and technical complexity.

[0003] The limitation of existing approaches lies in the fact that the separation of charging and storage functions results in low device integration, making it unable to meet the dual power and storage requirements of smartphones for long-duration video recording. While common power banks on the market can power phones through simple voltage output, they lack communication protocols with the phone, making it difficult to dynamically adapt to charging needs. Furthermore, storage expansion devices typically require independent power supplies or additional interfaces, limiting their convenience in mobile scenarios. These shortcomings expose the shortcomings of current technologies in multifunctional integration.

[0004] The core challenge lies in achieving efficient coordination between power management and data storage within a limited space. Specifically, dynamic adaptability of power management, seamless access to data storage, and coordinated control 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 needs of the phone. The integration of storage functions is limited by the synchronization of data transmission and power management. Furthermore, insufficiently precise logic design within the control unit can lead to system inefficiency or functional conflicts. These unresolved technical factors directly contribute to the unique challenge of the device's inability to simultaneously provide stable power and sufficient storage during long-duration video recording.

[0005] Therefore, the key issue in this research is how to design a circuit architecture that can dynamically manage battery charge and discharge, while seamlessly integrating storage functions while maintaining a power and data connection with the phone. Solving this problem will directly drive performance breakthroughs for portable devices in multiple application scenarios. Summary of the Invention
