Description

Technical Field

[0001] This application relates to the technical field of mobile device accessories, and particularly to a mobile device charging, storing, and protecting case with a detachable bracket. Background Art

[0002] With the popularization of mobile devices, smartphones and tablets have become indispensable tools in modern life. They not only have various functions such as communication, entertainment, and office work, but also are widely used in various fields due to their portability and high efficiency. However, since the screens of these devices are usually large, fragile, and may be worn and scratched after long-term use, the demand for protective cases has gradually increased.

[0003] As an effective external protection device, the protective case can effectively prevent mobile phones and tablets from being damaged by dropping, impact, and scratching during daily use. Currently, there are a wide variety of protective cases on the market, with materials including plastic, silicone, metal, and leather. In terms of design, they not only focus on the protection function but also take into account the appearance and feel. With the progress of technology, modern protective cases also incorporate more intelligent functions, such as brackets, wireless charging functions, antibacterial coatings, etc., making them not only simple protective tools but also accessories that enhance the user experience.

[0004] However, the existing protective cases have several defects that limit the optimization of the user experience. First, many protective cases have a single function and only provide basic protection functions, unable to meet the growing diverse needs of users. Although there are some multi-functional mobile phone cases on the market, they often have problems such as large volume and heavy weight, reducing the portability of the device. Second, some multi-functional mobile phone cases fail to balance the bracket function and the storage expansion function well, and the two cannot be achieved simultaneously, resulting in unnecessary compromises for users when choosing. In addition, the integration degree of the charging function and the storage expansion function in the existing protective cases is relatively low, and the two are usually designed independently, making it inconvenient to use. Finally, the structure of some protective cases is complex, which not only increases the production cost but also makes maintenance and replacement inconvenient, reducing the long-term use value of the product. These defects indicate that there is still a large room for improvement in the multi-functionality, convenience, and user experience of the existing protective cases. Summary of the Invention
