Technical Field

[0001] The utility model relates to the technical field of USB flash drives, in particular to a Bluetooth USB flash drive with a display screen. Background Art

[0002] With the progress of the times and the development of science and technology, people are pursuing a simpler and more convenient life. USB flash drives play an important role in life, especially in work. USB flash drives are a kind of flash memory, so they are sometimes called flash drives. USB flash drives are one of the most common flash memory devices in our daily work and life. Although they can only temporarily store a small amount of files, their lightweight and portable features have not affected their becoming a necessity for people.

[0003] However, anyone who has used a USB drive knows that although connecting a computer to a USB drive is simple, many people have to try two or three times or even more times before the connection is successful, which wastes time. Moreover, the connection between the USB drive and the mobile phone or work tablet still needs to be completed through a computer or other digital product as a transfer platform for data transmission, storage and retrieval, which brings great inconvenience to people's life, study and office.

[0004] However, when the inventor implemented this device, he found the following defects: the USB flash drive needs to be connected to the computer two to three times or even more times to be successful, which wastes time, and the connection with the mobile phone or work tablet needs to be completed by contacting the transfer platform, making it inconvenient to use. Utility Model Content

[0005] Based on this, it is necessary to provide a Bluetooth USB flash drive with a display screen to address the above technical problems. The USB plug can be directly inserted into the USB port of the computer to connect to the computer, and can be used as an ordinary USB flash drive in conjunction with a main control PC board and a flash memory chip for data transmission. The rechargeable lithium battery can be charged through a Type-C plug and used in conjunction with a Bluetooth module to enable the device to have a Bluetooth transmission function. On the basis of the original USB flash drive, the function of viewing or transmitting data without a transfer platform is added to ensure convenience of use.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A Bluetooth USB flash drive with a display screen, comprising:

[0008] A top shell, with a bottom shell installed below the top shell;

[0009] A USB plug is installed inside the left end of the top shell and the bottom shell, and a Type-C plug is installed inside the right end of the top shell and the bottom shell. A main control PC board, a flash memory chip, a Bluetooth module, a rechargeable lithium battery, a display screen and a switch button are arranged inside the bottom shell. The display screen is embedded and installed inside the top shell. A mounting hole is opened on the outer surface of the top shell, and the switch button is installed inside the mounting hole. The USB plug, the flash memory chip, the Bluetooth module, the rechargeable lithium battery, and the display screen are electrically connected to the main control PC board respectively, and the Type-C plug and the switch button are electrically connected to the rechargeable lithium battery respectively.

[0010] Furthermore, a dust cap is provided on the left side of the top shell.

[0011] Furthermore, a sealing strip is installed on the top surface of the bottom shell, a sealing groove is opened on the inner wall of the top shell, and the sealing strip is slidably installed inside the sealing groove.

[0012] Furthermore, the switch button is a normally closed switch.

[0013] Furthermore, a cover plate is rotatably mounted on the top surface of the top shell, and a dustproof plate is fixedly connected to the right end of the cover plate.

[0014] Furthermore, a side of the dustproof plate away from the cover plate is fixedly connected with an anti-slip strip, and the material of the anti-slip strip is silicone.

[0015] Furthermore, a lifting ring is fixedly connected to the outer surface of the dustproof plate.

[0016] Furthermore, the outer surface of the cover plate is provided with a mounting groove, and an elastic pressing plate is installed inside the mounting groove. The top surface of the top shell is provided with a positioning groove, the bottom surface of the elastic pressing plate is fixedly connected with a positioning ball block, and the elastic pressing plate is located inside the positioning groove.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The Bluetooth USB flash drive with a display screen provided by the utility model is directly plugged into the USB interface of a computer through a USB plug to connect to the computer, and is used as an ordinary U disk in conjunction with a main control PC board and a flash memory chip for data transmission. The rechargeable lithium battery is charged through a Type-C plug and used in conjunction with a Bluetooth module, so that the device has a Bluetooth transmission function, and a function of viewing data or transmitting data without a transfer platform is added on the basis of the original USB flash drive, thereby ensuring convenience of use.

[0019] When in use, push the cover and the dustproof plate to rotate half a circle so that the display screen displays the Bluetooth connection status. When the cover rotates, it rotates with the elastic pressure piece and the positioning ball block. Under the action of external force, the positioning ball block slides out of the positioning groove. The cover rotates half a circle so that the positioning ball block is located inside the mounting hole and squeezes the switch button to make it connected. After use, rotate the cover to reset the positioning ball block to enter the positioning groove to fix the elastic pressure piece and the cover. The cover protects the display screen, and the dustproof plate protects the Type-C plug to prevent dust from entering, thereby ensuring its safety in use. When the cover is reset, the positioning ball block separates from the switch button to automatically disconnect it, preventing the user from forgetting to turn off the power and keeping it powered on, resulting in power consumption and affecting the usage time.
