[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Figure 1 Schematically shows the structural diagram of the installation for a storage medium according to an embodiment of the present invention.

[0025] As Figure 1 shown, the installation structure for the storage medium includes an installation base 1, a first installation layer 6 for installing the storage medium and its control module, and a second installation layer 7 for installing the input module. The installation base 1, the first installation layer 6, and the second installation layer 7 are installed in sequence. The control module is a module for controlling the storage medium having this installation structure and can be implemented as chip control. The input module is a module for external input to the storage medium having this installation structure and can be a touch screen or a button, etc.

[0026] In this embodiment, the mounting base 1 is a rectangular groove-shaped box (which can also be designed into other shapes according to requirements in other embodiments). An accommodation groove 101 is formed in the middle part thereof. Two mounting bosses 102 are arranged in the accommodation groove 101. When the first mounting layer 6 is mounted to the mounting base 1, it is disposed on the mounting bosses 102. An accommodation space is formed between the first mounting layer 6 and the bottom surface of the accommodation groove 101. An opening 103 is provided on the mounting base 1. The opening 103 communicates with the accommodation space. And this mounting structure further includes a card holder 3 adapted to the opening 103. The card holder 3 is provided with a hollow hole to facilitate the insertion and extraction of the card during use. And the card holder 3 is connected to the opening 103 in a push-pull manner. A sealing ring 4 is sleeved on the port of the stop block 301 of the card holder 3, which can effectively prevent liquids such as water from entering the storage medium.

[0027] As Figure 1 shown, in a preferred embodiment, a second accommodation space 104 for placing a power module is further formed in the accommodation space. The power module can be implemented as a button battery, a square battery, etc. The second accommodation space is preferably designed to be adapted to the outer shape of the battery. Preferably, in this embodiment, the mounting structure further includes a pressing cover 2 adapted to the opening of the second accommodation space, and is disposed between the first mounting layer 6 and the second accommodation space. The pressing cover 2 can be buckled on the second accommodation space to cover the opening of the second accommodation space. Thus, when the second accommodation space 104 is equipped with a battery, the pressing cover 2 can be buckled to prevent the battery liquid of the battery from leaking out and corroding the control module of the storage medium.

[0028] As Figure 1 shown, as a preferred embodiment, the mounting structure further includes a third mounting layer 8 for relatively fixing the mounting base 1, the first mounting layer 6 and the second mounting layer 7. The third mounting layer 8 is disposed on the second mounting layer 7. The third mounting layer is a fixing plate, preferably made of lightweight silica gel. Screwdriver holes can be provided at corresponding positions of the third mounting layer 8, the second mounting layer 7, the first mounting layer 6 and the mounting base 1, and the mounting base 1, the first mounting layer 6, the second mounting layer 7 and the third mounting layer 8 can be relatively fixed by screws. Also, a buckling or pressing structure can be provided at the edge of the third mounting layer to press and fix the second mounting layer 7, the first mounting layer 6 and the mounting base 1. Or the convex column of the mounting base 1 can be set as a stud, which passes through the screw holes of the first mounting layer, the second mounting layer and the third mounting layer, and is fixed by the screw.

[0029] Preferably, the installation structure may further include a fourth installation layer 9 provided on the third installation layer 8. The fourth installation layer 9 is preferably a PC lens, and an adhesive or 3M tape is provided on its back. After the installation base 1, the first installation layer 6, and the second installation layer are relatively fixed, the fourth installation layer can be applied to the third installation layer to cover the fixed connection, making the product appearance beautiful and generous. And the PC lens has a certain waterproof effect, can better fit with the third installation layer, and protect the internal structure of the product. The grooves of the installation base 1, the first installation layer 6, the second installation layer 7, the third installation layer 8, and the fourth installation layer 9 are preferably of suitable sizes. For example, the first installation layer 6, the second installation layer 7, the third installation layer 8, and the fourth installation layer 9 can be adapted to the opening of the groove of the installation base 1. In this way, after installation, the installation base 1 is just buckled, making the product beautiful, the structure reasonable, and the material saved. In a preferred embodiment, the installation base 1, the first installation layer 6, the second installation layer 7, the third installation layer 8, and the fourth installation layer 9 are all detachably connected to facilitate the later maintenance of the structure and electronic components.

[0030] In this way, during the factory assembly line production and daily maintenance, only need to first place the installation base 1 at the bottom layer, stack the first installation layer 6, the second installation layer 7, and the third installation layer 8 in sequence, connect them by screws, then tear off the adhesive on the back of the fourth installation layer 9, and paste it on the third installation layer 8 to complete the installation of the storage medium.

[0031] Among them, the storage medium is not limited to media such as USB flash drives and external hard drives.

[0032] Those skilled in the art should understand that the features in the above structures can be selected separately or in combination according to needs. For example, the structure without a card holder and an opening can be set according to the product characteristics, or the second accommodation space and the pressure cover for the battery module can be not designed according to the product characteristics. The above embodiments are an optimal implementation example and should not be regarded as a limitation to the product structure.

Finally, the fourth installation layer 9, that is, the PC mirror panel, is pasted to the third installation layer 8 through the 3M glue on its back.

[0036] In another preferred embodiment, as Figure 4As shown in the figure, the encrypted mobile storage device further includes a SIM card identification chip 604 connected to the main control chip 6011. The SIM card identification chip is disposed on the first installation layer. Among them, the SIM card identification chip 604 can be the SIM card identification chip used in existing technologies such as mobile phones. The position where the chip is disposed on the first installation layer 6 is the same as the position where the card tray 3 is inserted into the installation base 1. When the SIM card is placed in the card tray and inserted into the installation base 1 through the opening 103 of the installation base 1, the SIM card can be in contact and conduction with the SIM card identification chip at the corresponding position to achieve communication. In this way, through customized services for the SIM card, operations such as GPS positioning, identity recognition, and password strengthening of the mobile storage device can be realized (the specific implementation can refer to the relevant existing technologies of the SIM application method).
