Technical Field
[0001] This utility model belongs to the field of mobile phone case technology, and in particular relates to a mobile phone case with memory expansion function. Background Technology
[0002] A mobile phone case is an outer cover designed and manufactured to protect a mobile phone. Its function has evolved from protection to aesthetics. The types of cases have diversified with the increase in mobile phone brands and functions. They can be categorized by material, such as leather, silicone, cloth, hard plastic, soft plastic, velvet, and silk, and by phone type, such as candybar and flip phones. Silicone cases are divided into two types: organic silicone and inorganic silicone. Most silicone phone cases on the market are of the former type. Organic silicone has many advantages, such as high temperature resistance, excellent weather resistance (not afraid of ultraviolet rays or ozone decomposition), good insulation, and material stability (it will not change with animal matter). In addition, people choose silicone cases because of their good feel; some phones with stiff keyboards are improved after using a silicone case. It can also absorb some of the impact from bumps and knocks, thus reducing damage to the phone.
[0003] Currently, mobile phone memory cannot be expanded. The memory card is fixed to the internal electronic components and cannot be removed or replaced. Furthermore, inserting a memory card to expand the memory would inevitably damage the original structure of the internal electronic components, leading to the manufacturer ceasing to provide after-sales service and maintenance. Therefore, we propose a mobile phone case with memory expansion functionality. Utility Model Content
[0004] The purpose of this invention is to provide a mobile phone case with memory expansion function to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a mobile phone case with memory expansion function, comprising:

[0008] A rubber sheet is disposed inside the phone case and covers the storage slot and ribbon cable.
[0009] In this technical solution, the memory card, flex cable, and Type-C connector are designed to be placed in the storage slot, and the flex cable is placed in the cable slot with the Type-C connector positioned below the port. Then, a rubber sheet is used to cover the memory card, flex cable, and storage slot to ensure the phone case's aesthetics. The user can then place the phone inside the case and insert the Type-C connector into the phone's charging port to expand the phone's memory. This ensures that expanding the phone's memory does not damage the internal electronic components, and that the phone can receive after-sales service and maintenance.
[0010] In the above technical solution, the two corners of the bottom side of the rubber sheet are rounded, and a number of insert blocks are fixedly installed on the side of the rubber sheet near the inner wall of the phone case, and limit blocks are fixedly installed on the insert blocks.
[0011] In this technical solution, the two corners on the bottom side of the rubber sheet are rounded to prevent the two corners at the bottom of the rubber sheet from being squeezed against the inner wall of the phone case, and also to save materials generated during the production of the rubber sheet.
[0012] In the above technical solution, the limiting block is a right-angled trapezoidal structure, and the inclined side of the limiting block faces the inner wall of the mobile phone case. The insert block and the limiting block are integrally formed.
[0013] In this technical solution, the structural stability of the insert block and the limiting block is ensured.
[0014] In the above technical solution, further, a plurality of limiting grooves are provided on the inner wall of the mobile phone case, and the insert block and the limiting block form a limiting structure, with one end of the insert block and the limiting block located in the limiting groove.
[0015] In this technical solution, after the memory card is installed in the storage slot and the ribbon cable is installed in the ribbon cable slot, a rubber sheet covers the memory card, ribbon cable and storage slot. At the same time, one end of the insert block and the limiting block are inserted into the limiting slot to reinforce the rubber sheet, ensure the structural stability of the rubber sheet and ensure the aesthetics of the phone case.
[0016] Furthermore, the above technical solution also includes:
[0017] A rectangular groove is formed on the rubber sheet near the storage slot. A connecting strip is fixedly installed on the inner wall of the phone case near the storage slot. One side of the connecting strip passes through the rectangular groove and is fixedly installed with a limit strip.
[0018] In this technical solution, after the memory card is installed in the storage slot and the ribbon cable is installed in the ribbon cable slot, the limiting strip passes through the rectangular slot and is tightly attached to one side of the rubber sheet, and the connecting strip is inserted into the rectangular slot to ensure that the rubber sheet further fixes the memory card in the storage slot.
[0019] In the above technical solution, the connecting strip and the limiting strip are integrally formed, and both the connecting strip and the limiting strip are inserted into the rectangular groove.
[0020] In this technical solution, the structural stability of the connecting strip and the limiting strip is ensured, and the connecting strip and the limiting strip can be inserted into the rectangular groove.
[0021] In the above technical solution, furthermore, the two ends of the ribbon cable are electrically connected to the memory card and the Type C plug, respectively.
[0022] In this technical solution, it is ensured that when the Type-C plug is inserted into the charging port on the phone, the phone's memory expansion is completed after the phone is powered on. This ensures that the phone's internal electronic components are not damaged during memory expansion, and the phone can still receive after-sales service and maintenance later.
[0023] The beneficial effects of this utility model are:
[0024] This phone case with memory expansion capability allows you to place the memory card in the storage slot, align the flex cable in the cable slot with the Type-C connector below the charging port, and then cover the memory card, flex cable, and storage slot with a rubber sheet to ensure the case's aesthetics. You can then place your phone inside the case and insert the Type-C connector into the phone's charging port to expand the memory. This process ensures that the phone's internal electronic components are not damaged during memory expansion, and the phone can still receive after-sales service and maintenance.
