[0024] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0025] In the description of this application: unless otherwise specified, the meaning of "plurality" is two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0026] The terms such as "upper", "lower", "left", "right", "middle", etc. cited in this application are usually used to indicate the general relative position relationship for the purpose of intuitive understanding by referring to the drawings, and are not absolute limitations on the position relationship in the actual product.

[0027] See also Figure 1 and Figure 2The present application provides an integrated storage expansion mobile phone case, including a mobile phone case body 1 and a male-female integrated plug 2. A cavity for accommodating a mobile phone is provided inside the mobile phone case body 1. A through hole 101 is provided on the side wall of the mobile phone case body 1. The position of the through hole 101 matches the position of the mobile phone charging port. The male-female integrated plug 2 is fixedly arranged in the through hole 101. The male head 201 of the male-female integrated plug is located inside the mobile phone case body 1. The female head 202 of the male-female integrated plug is flush with the outer wall of the mobile phone case body 1. A storage chip 3, a current controller 4 and a circuit connector 5 are embedded in one end of the mobile phone case body 1 near the through hole 101. One end of the circuit connector 5 is electrically connected to the storage chip 3 and the current controller 4. The other end of the current controller 4 is electrically connected to the storage chip 3. The other end of the circuit connector 5 is electrically connected to the male-female integrated plug 2.

[0028] Specifically, the main function of the mobile phone case body 1 is to protect the mobile phone from external impact, scratches, dust, etc., and also to improve the appearance and feel of the mobile phone. Therefore, in the integrated storage expansion mobile phone case provided by the present application, the mobile phone case body 1 is made of hard plastic or composite material.

[0029] Hard plastics have strong pressure resistance and scratch resistance. Common hard plastic materials include polycarbonate (PC) and polypropylene (PP). Among them, PC is a high-strength plastic with good impact resistance and can effectively absorb external forces, thereby protecting the phone from damage. In addition, PC material also has good heat resistance and transparency. It is not only durable but also maintains the original appearance of the phone. PP is a relatively light and durable plastic with good toughness and wear resistance. It is often used to produce relatively simple and light mobile phone cases.

[0030] Composite materials are usually made of two or more different materials combined through a specific process, which can give full play to the advantages of each material and make up for the shortcomings of a single material. Common composite materials include silicone and hard plastic composites, carbon fiber composites and aluminum alloy composites. Among them, silicone and hard plastic composites are common in soft and hard mobile phone cases. The silicone part can provide better anti-slip and shock absorption, and the hard plastic part strengthens the structural strength and impact resistance of the mobile phone case; carbon fiber composite materials have extremely high strength, heat resistance and pressure resistance, so mobile phone cases made of this material are very light and strong, which can effectively protect the mobile phone from impact without adding too much weight; aluminum alloy composite materials are widely used in mobile phone cases. They can provide better impact resistance and good heat dissipation. Mobile phone cases made of aluminum alloy composite materials usually have a higher texture and metallic luster.

[0031] Specifically, in an integrated storage expansion mobile phone case provided by the present application, the male and female integrated plug 2 is an integrated design, and the male head 201 of the male and female integrated plug is used to connect to the charging port of the mobile phone 6, such as Figure 3 As shown, the female end 202 of the male-female integrated plug is used to connect to the charger of the mobile phone 6, so that the mobile phone 6 can expand the storage capacity of the mobile phone without affecting the normal charging of the mobile phone, and has no other additional functions.

[0032] More specifically, the male head 201 of the male-female integrated plug can be a plug such as USB or Lightning, and correspondingly, the female head 202 of the male-female integrated plug is an interface such as USB or Lightning. Among them, the USB plug is a plug such as Micro-B or Type-C, and correspondingly, the USB interface is an interface such as Micro-B or Type-C, so as to be compatible with all different models of mobile phones currently on the market.

[0033] Specifically, in an integrated storage expansion mobile phone case provided by the present application, the storage chip 3 adopts a UFS (universal flash storage) storage chip, supports fast storage and reading functions (reading speed of 2100MB / s and writing speed of 1200MB / s), ensures that the data transmission speed reaches more than 800MB / s, thereby meeting the high-performance storage requirements; the capacity of the storage chip is 128GB to 1TB, and the preferred capacity is 256GB. In the present application, the storage chip 3 is electrically connected to the male head 201 of the male and female integrated plug through the current controller 4, and then connected to the mobile phone 6. When the mobile phone case is connected to the charging port of the mobile phone 6, the storage chip 3 communicates with the mobile phone through the data transmission protocol to realize the storage expansion function.

[0034] Specifically, in an integrated storage expansion mobile phone case provided by the present application, the current controller 4 can dynamically adjust the flow direction and intensity of the current in the circuit to ensure the stability of the expansion storage and mobile phone charging functions, and ensure that the charging efficiency of the mobile phone is not affected while the storage is expanded. At the same time, the current controller 4 uses an integrated IC module, which further reduces the volume of the expansion component, makes the mobile phone case thinner and lighter, and enhances the user's grip.

[0035] In the integrated storage expansion mobile phone case provided by the present application, the mobile phone case body 1 is integrally formed with the male and female integrated plug 2, the storage chip 3, the current controller 4 and the circuit connector 5, and adopts an integrated circuit design to ensure seamless connection and data transmission with the mobile phone. This design can expand the storage capacity of the mobile phone and maintain the charging function without affecting the normal use of the mobile phone, while simplifying the operation process and improving the user experience.

[0036] It should be noted that the memory chip 3 , the current controller 4 and the circuit connector 5 adopt a modular packaging design, which facilitates the maintenance and replacement of the memory chip 3 .

[0037] The integrated storage expansion mobile phone case provided by the present application has the following advantages:

[0038] 1. Simple structure: This application not only expands the storage capacity of the mobile phone without affecting the charging function of the mobile phone, but also reduces additional interfaces and functions (for example, the integration of non-core functions such as headphone jack and sliding USB interface), thereby improving the overall design compactness and reliability.

[0039] 2. Structural optimization: By embedding the female head of the male-female integrated plug into the shell, the external interface is reduced, the integrity and aesthetics of the structure are enhanced, and the durability of the product is improved.

[0040] 3. Easy to use: Through the design of integrated molding with the mobile phone case, users only need to insert the mobile phone to achieve storage expansion without additional operation.

[0041] 4. Strong compatibility: The designed interface layout is consistent with mainstream smartphones, does not affect the charging operation, and ensures a good user experience.

[0042] 5. Cost optimization: After streamlining functions, manufacturing costs are reduced and the market competitiveness of products is improved.

[0043] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
