Referring to
In particular, the main function of the mobile phone case body 1 is to protect the mobile phone from external impacts, scratches, dust, and other damage, while also improving the appearance and hand feeling of the mobile phone. Therefore, the present application provides an integrated storage expansion mobile phone case, where the mobile phone case body 1 is made of a rigid plastic or a composite material.
The rigid plastic exhibits strong compression resistance and scratch resistance. Common rigid plastic materials include polycarbonate (PC) and polypropylene (PP), and the like. PC is a high-strength plastic that has good impact resistance and is capable of effectively absorbing external forces to protect the mobile phone from damage. Additionally, the PC material has excellent heat resistance and transparency, not only making it durable but also maintaining the original appearance of the mobile phone. PP is a lightweight, durable plastic with good toughness and wear resistance, and is commonly used to produce simple, lightweight mobile phone cases.
Composite materials are typically formed by combining two or more different materials through a specific process, making full use of the advantages of each material and making up for the shortcomings of a single material. Common composite materials include silicone and rigid plastic composites, carbon fiber composite materials, and aluminum alloy composite materials. The silicone and rigid plastic composites are commonly used in flexible-and-rigid mobile phone cases. The silicone part provides better anti-slip and shock absorption, while the rigid plastic part enhances the structural strength and impact resistance of the mobile phone case. The carbon fiber composite materials offer extremely high strength, heat resistance, and compression resistance, making mobile phone cases made of this material very light, thin, and sturdy, and thus effectively protecting the mobile phone from impact without adding excessive weight. The aluminum alloy composite materials are widely used in mobile phone cases, providing both good impact resistance and effective heat dissipation. Mobile phone cases made of the aluminum alloy composite materials typically feature a high-quality feel and a metallic luster.
In particular, in the integrated storage expansion mobile phone case provided by the present application, the combined male-female connector 2 features an integrated design. The male connector 201 of the combined male-female connector is configured to connect to the charging port of the mobile phone 6, and as shown in
More particularly, the male connector 201 of the combined male-female connector may be a USB or Lightning plug or the like, and correspondingly, the female connector 202 of the combined male-female connector may be a USB or Lightning interface or the like. The USB plug may be a Micro-B or Type-C plug or the like, and correspondingly, the USB interface may be a Micro-B or Type-C interface or the like, making it compatible with all mobile phones of different models currently available on the market.
In particular, in the integrated storage expansion mobile phone case provided by the present application, the memory chip 3 is a universal flash storage (UFS) memory chip, supporting fast storage and reading functions (at a read speed of 2100 MB/s and a write speed of 1200 MB/s), ensuring that the data transfer speed exceeds 800 MB/s, thereby meeting the requirements for high-performance storage. The memory chip has a capacity ranging from 128 GB to 1 TB, preferably of 256 GB. In the present application, the memory chip 3 is electrically connected to the male connector 201 of the combined male-female connector through the current controller 4, and then connected to the mobile phone 6. After the mobile phone case is connected to the charging port of the mobile phone 6, the memory chip 3 communicates with the mobile phone via a data transfer protocol to achieve the storage expansion function.
In particular, in the integrated storage expansion mobile phone case provided by the present application, the current controller 4 can dynamically adjust the direction and intensity of the current in the circuit, ensuring the stability of both the storage expansion and mobile phone charging functions, and ensuring that the charging efficiency of the mobile phone is not affected while the storage is expanded. At the same time, the current controller 4 is an integrated IC module, further reducing the size of the expansion component, making the mobile phone case thinner and lighter, and improving the user's grip.
In the integrated storage expansion mobile phone case provided by the present application, the combined male-female connector 2, the memory chip 3, the current controller 4, and the circuit connector 5 are each integrally formed on the mobile phone case body 1 using an integrated circuit design to ensure seamless connection and data transfer with the mobile phone. The design not only expands the storage capacity of the mobile phone but also maintains the charging function without affecting the normal use of the mobile phone. Additionally, the design simplifies the operation process and improves the user experience.
It is to be noted that the memory chip 3, the current controller 4, and the circuit connector 5 adopt a modular packaging design, facilitating the maintenance and replacement of the memory chip 3.
The integrated storage expansion mobile phone case provided by the present application has the following advantages:
1. Simple structure: The present application not only expands the storage capacity of the mobile phone without affecting the charging function, but also reduces additional interfaces and functions (for example, the integration of non-core functions like a headphone jack and a sliding USB interface, etc.), thereby improving the overall design compactness and reliability.
2. Optimized structure: By embedding the female connector of the combined male-female connector into the case, the external interfaces are reduced, leading to improved structural integrity and aesthetics, and improved product durability.
3. Ease of use: By means of the integrated molding design of the mobile phone case, users can expand the storage simply by inserting the mobile phone, without any additional operations.
4. Strong compatibility: The interface layout is designed to be consistent with that of mainstream smartphones, ensuring that charging operations are unaffected, and providing good user experience.
5. Optimized cost: By streamlining the functions, the manufacturing cost is lowered, while the market competitiveness of the product is improved.
The technical features of the embodiment hereinabove may be combined arbitrarily as long as there is no contradiction in the combination of these features. For the brevity of description, not all possible combinations of the technical features in the embodiment hereinabove are described, and those embodiments not mentioned explicitly shall also be considered to fall within the scope as set forth in this specification.
