DETAILED DESCRIPTION

[0014] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] The structural diagram of the file protection type USB flash drive provided by the present invention is as follows: Figure 1 As shown, it includes a USB interface 1, a housing 2, a solar charging device 3, a USB charging device 4, a file protection device 5 and a USB disk software. The USB interface 1 is connected to the USB charging device 4 and the file protection device 5 respectively, the solar charging device 3 and the USB charging device 4 are connected to the file protection device 5 respectively, and the USB disk software is installed in the file protection device 5.

[0016] The solar charging device 3 is used to charge the file protection device 5 when the USB flash drive is not working. Figure 2 As shown, it includes a solar cell group 31 and a power module 32. The solar cell group 31 is fixed on the housing 2, the solar cell group 31 and the power module 32 are connected to each other, and the power module 32 and the document protection device 5 are connected to each other.

[0017] The USB charging device 4 is used to charge the file protection device 5 when the USB flash drive is plugged into the computer. Figure 3As shown, it includes a charging circuit module 41, a rechargeable battery 42 and a voltage stabilizing circuit module 43. The charging circuit module 41, the rechargeable battery 42 and the voltage stabilizing circuit module 43 are connected in sequence, the charging circuit module 41 is connected to the USB interface 1, and the voltage stabilizing circuit module 43 is connected to the file protection device 5, which plays a role in stabilizing the circuit voltage and ensuring the safety of the file protection device 5.

[0018] The structural diagram of the file protection device 5 is as follows Figure 4 As shown, it includes a microprocessor 51, a memory 52, a buzzer 53, an antenna 54, a GPS module 55, a Bluetooth module 56 and a GMS module 57. The microprocessor 51 is respectively connected to the memory 52, the buzzer 53, the antenna 54, the GPS module 55, the Bluetooth module 56, the GMS module 57, the USB interface 1, the power module 32 and the voltage stabilizing circuit module 43 to play a control role. The U disk software is installed in the microprocessor 51. The memory 52 is used to store user data. The Bluetooth module 56 is used to pair with the mobile phone and control the buzzer 53 to sound an alarm to guide the search of the U disk. The GPS module 55 is used to locate the U disk. The GMS module 57 and the antenna 54 are used to connect to the cloud database to back up the files in the U disk to the cloud to reduce the loss caused by the loss of files.

[0019] The present invention provides the following two USB flash drive charging modes:

[0020] Mode 1: When the USB flash drive is plugged into a computer and used, it is charged by the USB charging device 4. The charging circuit module 41 stores the electric energy in the rechargeable battery 42 through the USB interface 1, and the rechargeable battery 42 then provides electric energy for the file protection device 5. A voltage stabilizing circuit module 43 is connected between the rechargeable battery 42 and the file protection device 5 to stabilize the circuit voltage and ensure the safety of the file protection device 5.

[0021] Mode 2: When the USB flash drive is not working, it is charged by the solar charging device 3. When the USB flash drive is placed near a light source, the solar cell group 31 fixed on the housing 2 can convert light energy into electrical energy and send it to the power module 32, which then supplies power to the file protection device 5.

[0022] The present invention provides the following three USB file protection solutions for users:

[0023] Solution 1: When the USB flash drive is placed near the user and the user forgets its specific location, the user turns on the mobile phone Bluetooth and searches for the Bluetooth module 56 of the USB flash drive within the effective Bluetooth search range (the Bluetooth module 56 of the USB flash drive is always turned on when not working). After searching, enter the unique pairing code. After the pairing is successful, send a buzzer control instruction to the microprocessor 51 in the mobile phone software, so that the Bluetooth module 56 controls the buzzer 53 to sound an alarm, thereby guiding the search for the USB flash drive. When the USB flash drive is found, send an instruction to the microprocessor 51 again through the mobile phone software to confirm that the USB flash drive has been found, and turn off the buzzer 53 at the same time.

[0024] Solution 2: When the location where the USB flash drive is lost is not near the user, the mobile phone software is opened, and instructions are first sent to the microprocessor 51 to encrypt the files in the USB flash drive and restrict access rights to ensure the security of the files. Then, the location information sent back by the GPS module 55 is accurately located, and the USB flash drive is searched there to avoid blindly searching for the USB flash drive, thereby improving the success rate of retrieving the USB flash drive. When the USB flash drive is found, instructions are sent to the microprocessor 51 again through the mobile phone software to confirm that the USB flash drive has been found, and the encryption and access rights restrictions of the files in the USB flash drive are released at the same time.

[0025] Solution 3: If the USB flash drive is still not found through Solution 1 and Solution 2, the mobile phone software sends instructions to the microprocessor 51, and the files in the USB flash drive are uploaded to the user's mobile phone through the network through the GMS module 57. At the same time, the USB flash drive is formatted so that the user's files are intact and the file confidentiality is also guaranteed.

[0026] Those skilled in the art will appreciate that the embodiments described herein are intended to help readers understand the principles of the present invention, and should be understood that the protection scope of the present invention is not limited to such specific statements and embodiments. Those skilled in the art can make various other specific variations and combinations that do not deviate from the essence of the present invention based on the technical revelations disclosed by the present invention, and these variations and combinations are still within the protection scope of the present invention.
