[0057] Example 1

[0058] The embodiment of the present application provides a protective case with expandable memory, specifically, as shown in Figures 1 to 5, comprising: a housing 1 for accommodating a smart terminal, and an expansion unit 2 provided on the housing 1 for memory expansion;

[0059] Optionally, the material of the housing 1 may be silicone, thermoplastic polyurethanes (TPU), polycarbonate (PC), or acrylonitrile butadiene styrene (ABS) copolymer.

[0060] Specifically, in some embodiments of the present application, the shell 1 is made of PC material with strong impact resistance, good toughness, good heat dissipation performance, high transparency, non-toxicity and safety, and easy processing and molding.

[0061] There is no restriction on the specific shape of the shell 1, and it can be made according to smart terminals of different sizes, shapes, and models. It only needs to meet the conditions that the outer shape of the shell 1 matches the shape of the smart terminal, the shell 1 can accommodate the smart terminal, and protect the smart terminal.

[0062] Optionally, the expansion unit 2 can be detachably set on the shell 1. The detachable setting has strong flexibility and is convenient for maintenance and installation; it can also be fixed on the shell 1. The immovable fixed connection is more stable and not easy to fall off; there is no restriction on the connection method and setting method of the expansion unit 2.

[0063] The housing 1 is provided with a camera hole 11 and a data connector hole 12. The camera hole 11 is provided at one end of the housing 1, and the data connector hole 12 is provided at the other end of the housing 1.

[0064] The expansion unit 2 includes an expansion circuit module 201 and a storage medium 202; the storage medium 202 is arranged on the expansion circuit module 201, and the expansion circuit module 201 is connected to a data connector 204 via a data line 203;

[0065] The expansion circuit module 201 may be provided with one or at least two storage media 202, and the storage media 202 is used for data storage;

[0066] Specifically, in some embodiments of the present application, only one storage medium 202 is provided. Providing only one storage medium 202 helps to simplify the internal structure of the expansion unit 2, reduce the volume of the expansion unit 2, reduce the space required for the expansion unit 2, and thereby simplify the external structure of the protective shell.

[0067] The expansion unit 2 is arranged at an end of the housing 1 close to the camera hole 11; the data connector 204 is arranged at an end of the housing 1 away from the camera hole 11;

[0068] It is understandable that, generally speaking, the camera of a smart terminal tends to protrude from the outer surface of the smart terminal, and the camera hole 11 tends to protrude from the surface of the protective shell in order to better protect the camera, that is, the back of the protective shell is often uneven.

[0069] In many smart device protective case designs, the space around the camera is relatively underutilized. Designing the expansion unit 2 in this location can better utilize this space without having to redesign the protective case layout, thus avoiding the protective case being too thick and bulky and maintaining portability.

[0070] The design of the protective case focuses on aesthetics and integrity. The expansion unit 2 is designed to be relatively concealed and placed next to the camera hole 11, so that the appearance of the protective case remains neat and tidy, and the additional expansion unit 2 will not affect the aesthetics.

[0071] The storage medium 202 , the expansion circuit module 201 , and the data connector 204 are electrically connected to each other. When the data connector 204 is connected to the charging port of the smart terminal, data interaction between the smart terminal and the storage medium 202 is achieved.

[0072] Optionally, the above-mentioned intelligent terminal includes an intelligent terminal arranged in the housing 1 and an intelligent terminal located outside;

[0073] The smart terminal disposed in the housing 1 may include a mobile phone or a tablet computer, etc.;

[0074] External smart terminals may include mobile phones, tablet computers, laptops, desktop computers, smart watches, smart speakers, and other electronic devices that have computing, storage, and communication capabilities, and have operating systems and support application programs.

[0075] The expansion circuit module 201 is used to control the data transmission between the smart terminal and the storage medium 202; the storage medium 202 is used for storage expansion and data exchange, realizing the function of expanding the storage space of the smart terminal set in the shell 1, transferring and storing the smart terminal data in the storage medium 202 set on the expansion circuit module 201, and the smart terminal can also read data from the storage medium 202, effectively increasing the storage space available for the smart terminal, making the operation of the smart terminal smoother, and can also store more data to meet the user's usage needs.

[0076] Optionally, the expansion circuit module 201 may include a USB adapter board of models such as CH376S and FT232RL; may also include a SATA adapter board of models such as ASM1153E and ASM1156; may also include a PCIe expansion board of models such as ASM2362 and JMicron JMS583;

[0077] Optionally, the storage medium 202 may be an external memory card, a USB flash drive, a mobile solid-state drive, or a mobile hard drive, and there is no limitation on the choice of the storage medium 202 ;

[0078] Specifically, in some embodiments of the present application, the storage medium 202 uses an external memory card; optionally, the external memory card can be a TF card, an SD card or a MINI-SD card, or a FLASH card.

[0079] Optionally, the data connector 204 includes a TYPE-C connector, a USB connector, or a Lightning connector; and meets the use requirements of different smart terminal interfaces, without limitation.

[0080] Specifically, in some embodiments of the present application, a Lightning connector is used.

[0081] Furthermore, as shown in FIG1 , the housing 1 is further provided with a mounting structure 14 and a mounting seat 13 ;

[0082] Specifically, in some embodiments of the present application, the mounting structure 14 is a mounting groove.

[0083] The shape of the mounting seat 13 matches the shape of the mounting structure 14, and the mounting seat 13 and the mounting structure 14 are movably connected;

[0084] The mounting base 13 is provided with a data connector hole 12;

[0085] The data connector 204 is set on the mounting base 13 through the data connector hole 12. The data connector 204 passes through the data connector hole 12 and protrudes into the shell 1. When the smart terminal is placed in the shell 1, the smart terminal is connected to the data connector 204 to realize data interaction between the smart terminal and the storage medium 202, thereby realizing the expansion of the smart terminal memory.

[0086] Furthermore, corresponding sliding grooves 141 are provided on both side walls of the mounting structure 14 , and corresponding sliding columns 131 are provided on both sides of the mounting seat 13 ;

[0087] The housing 1 is further provided with a protrusion 142 ; the protrusion 142 abuts against the connection mounting seat 13 ;

[0088] The sliding post 131 matches the sliding slot 141 , so that the mounting seat 13 can slide in the mounting structure 14 along the extending direction of the sliding slot 141 . The length of the sliding slot 141 is the movable length of the mounting seat 13 .

[0089] On the one hand, the cooperation between the sliding column 131 and the sliding groove 141 can ensure that the direction of the sliding movement is always consistent, preventing deflection during the sliding process, and playing a guiding role.

[0090] On the other hand, the sliding posts 131 and the sliding slots 141 on both sides can disperse the load and provide greater stability, especially when subjected to lateral force or torque.

[0091] On the other hand, the sliding post 131 and the sliding slot 141 can serve as additional connection points to enhance the stability of the connection between the sliding post 131 and the sliding slot 141 .

[0092] When the mounting base 13 is moved away from the housing 1 to release the abutment connection between the mounting base 13 and the protrusion 142 , the sliding post 131 can also be used to flip the mounting base 13 so that the data connector 204 is removed from the charging port of the smart terminal.

[0093] Furthermore, the housing 1 has a stepped boss 15 for accommodating the expansion unit 2 , and the boss 15 is located at the edge of the outline of the camera hole 11 .

[0094] Specifically, in some embodiments of the present application, the camera hole 11 is located on the left side away from the data connector hole 12, and the expansion unit 2 is located on the right side away from the data connector hole 12. The camera hole 11 and the expansion unit 2 are arranged in one place, which can make full use of the space around the camera hole 11, optimize the grip of the protective case, and do not affect the user's normal grip and carrying.

[0095] Preferably, the thickness of the boss 15 is not greater than the thickness of the camera hole 11 ; this helps to maintain the original thickness of the protective shell as much as possible, minimize the impact on the protective shell, and at the same time minimize the impact on the user's sense of use and experience.

[0096] More preferably, the boss 15 is the same thickness as the camera hole 11 and is flush with the camera hole 11. This equal thickness makes the protective case more stable when placed flat, reducing the shaking and instability caused by the camera protrusion. Keeping the boss 15 flush with the camera hole 11 prevents the camera from directly contacting the table or other hard surfaces, reducing the risk of scratching the camera lens. The same thickness of the boss 15 as the camera hole 11 provides a larger support area, making the smart terminal more stable when placed flat, and reducing the possibility of the smart terminal tilting or shaking due to the camera protrusion.

[0097] Optionally, the boss 15 is integrally formed with the housing 1; specifically as shown in FIG5, FIG6, FIG8 and FIG12,

[0098] The one-piece design provides a more robust and stable structure, effectively enhancing the dust and water resistance of the protective case, protecting the smart terminal and the internal devices of the expansion unit 2 from external environmental influences. It also creates a simpler and more streamlined appearance, reducing visual distractions caused by joints or seams, and improving the aesthetics of the product.

[0099] Optionally, as shown in FIG2 and FIG4 , the boss 15 is detachably provided on the housing 1 ;

[0100] The detachable setting is that the boss 15 is detachable and designed for flexible replacement. The boss can be replaced according to personal preferences and needs. When the expansion unit 2 or the boss 15 is damaged, the detachable setting also facilitates maintenance.

[0101] After the boss 15 is removed, it is easier to clean or wipe the surface of the protective shell and the boss 15 to remove dust and keep the appearance of the protective shell clean.

[0102] Furthermore, the thickness of the boss 15 is between 0.5 mm and 5 mm.

[0103] The thickness of the boss 15 can be determined according to the thickness of the camera of the smart terminal. In this respect, the thickness of the boss 15 is less likely to affect the normal use of the smart terminal and has better portability.

[0104] For example, if the camera of the smart terminal protrudes 1.5 mm from the outer surface of the smart terminal, the thickness of the boss 15 can be designed to be 1.5 mm.

[0105] Of course, there is no limitation on the specific thickness of the boss 15 .

[0106] Furthermore, as shown in FIG2 , FIG3 , FIG7 and FIG9 , the housing 1 includes a housing cavity 31 for accommodating the smart terminal, and at least one layer of a function expansion cavity 32 ;

[0107] At least two grids 321 are provided in the function expansion cavity 32;

[0108] The design of the grid 321 structure, on the one hand, helps to reduce the use of materials and lower the material cost of production. On the other hand, it helps to reduce the weight of the shell 1, enhance portability, and also helps air to enter, play a role in heat dissipation, and extend the service life of the components.

[0109] The function expansion cavity 32 is further provided with a wire groove 322 for accommodating the data wire 203 . One end of the wire groove 322 is close to the expansion unit 2 , and the other end of the wire groove 322 is close to the data connector hole 12 .

[0110] The setting of the function expansion cavity 32 avoids the data line 203 being directly exposed outside the protective shell, reducing the risk of damage; of course, in addition to accommodating the data line 203, it can also accommodate electronic components such as batteries and indicator lights to achieve more diversified functional expansion of the protective shell.

[0111] The wire groove 322 is provided to further protect the data line 203 . Of course, the provision of the wire groove 322 also helps to arrange the data line 203 neatly, facilitates organization, and reasonably plans the internal space of the housing 1 .

[0112] Therefore, the embodiment of the present application provides a protective shell with expandable memory, including: an expansion unit 2 including an expansion circuit module 201 and a storage medium 202, the expansion unit 2 is arranged at one end close to the camera hole 11, and the data connector 204 is arranged at the end away from the camera hole 11. Data exchange and data storage are carried out with the smart terminal through the arranged storage medium 202, which can expand the memory of the smart terminal and solve the problem of insufficient memory of the smart terminal; a boss 15 is provided to protect the expansion unit 2, and the layout of the expansion unit 2 on the protective shell is optimized, so that the shell 1 is more portable, which solves the problem that the shell 1 is relatively thick and bloated, and a mounting seat 13 and a mounting structure 14 are provided to install the data connector 204, so that the connection of the data connector 204 is more stable and the use of the data connector 204 is more convenient; thereby improving the user experience.

[0113] Example 2

[0114] The embodiment of the present application provides a protective case with expandable memory, as shown in FIG5 to FIG8 , comprising: a housing 1 for accommodating a smart terminal, and an expansion unit 2 for memory expansion;

[0115] The housing 1 is provided with a camera hole 11;

[0116] The expansion unit 2 includes an expansion circuit module 201 and a storage medium 202; the storage medium 202 is arranged on the expansion circuit module 201, and the expansion circuit module 201 is connected to a data connector 204 via a data line 203;

[0117] The expansion unit 2 is arranged at an end of the housing 1 close to the camera hole 11; the data connector 204 is arranged at an end of the housing 1 away from the camera hole 11;

[0118] The storage medium 202 , the expansion circuit module 201 , and the data connector 204 are electrically connected to each other to implement data interaction between the smart terminal and the storage medium 202 .

[0119] Further, as shown in FIG5 , the cross-sectional shape of the mounting seat 13 includes an isosceles trapezoid, and the cross-sectional shape of the mounting structure 14 includes an isosceles trapezoid;

[0120] The width of the mounting structure 14 gradually increases along the bottom of the housing 1 toward the data connector hole 12 .

[0121] There is no limitation on the specific forms of the mounting structure 14 and the mounting seat 13 .

[0122] The width of the mounting structure 14 gradually increases along the bottom of the housing 1 toward the data connector hole 12. That is, the mounting structure 14 is wider at the top and narrower at the bottom. This increases the contact area between the mounting structure 14 and the mounting seat 13, providing good stability and support. When the mounting seat 13 moves within the mounting structure 14, gravity prevents the mounting seat 13 from falling out of the mounting structure 14.

[0123] The isosceles trapezoidal cross-section design of the mounting structure 14 and the mounting base 13 provides excellent guidance, making the mounting base 13 stable during movement, reducing the possibility of skewing or jamming, and making installation and removal operations intuitive and convenient;

[0124] Moreover, when subjected to forces perpendicular to the extension direction, the isosceles trapezoidal structure can distribute these forces more evenly, reduce local stress concentration, make the overall structure more compact, and improve the durability of the structure.

[0125] In addition, the narrower lower end can reduce the chance of dust and dirt entering the interior of the mounting structure 14, helping to keep the interior of the mounting structure 14 clean and reduce maintenance frequency.

[0126] Furthermore, as shown in FIG10 , a flexible folding portion 132 is provided on the mounting base 13 . When the flexible folding portion 132 is folded along an area away from the charging port of the smart terminal, the data connector 204 is moved out of the charging port of the smart terminal.

[0127] By folding the flexible folding portion 132 , the data connector 204 can be removed from the data connector hole 12 without affecting the normal use of the mobile phone charging function.

[0128] Optionally, the flexible folding portion 132 is made of a flexible material, such as silicone, thermoplastic polyurethane elastomer rubber, or polycarbonate.

[0129] Furthermore, as shown in Figures 8, 10 and 11, a slot 151 is provided on the side wall of the boss 15, and the slot 151 is used to expose the storage medium interface 153, and the storage medium interface 153 is used to connect the storage medium 202; a cover 152 for closing the slot 151 is movably provided on the outside of the slot 151, and the cover 152 is connected to the slot 151.

[0130] The shape and size of the storage medium interface 153 depend on the specific situation and type of the storage medium 202 , and there is no limitation on the specific shape of the storage medium interface 153 .

[0131] Exemplarily, when the storage medium 202 is a memory card, the storage medium interface 153 is a card slot.

[0132] By using the storage medium interface 153 , the user can replace the storage medium 202 according to actual usage requirements or preferences to adapt to different usage scenarios.

[0133] The slot 151 is designed to facilitate the taking and placing of the storage medium 202 , and is also convenient for maintenance and installation. The provision of a cover 152 for closing the slot 151 is also beneficial for preventing dust from entering and protecting the storage medium 202 .

[0134] The rest of the contents that are the same as those in Example 1 are not repeated here.
