Description

Technical Field

[0001] The utility model relates to the technical field of USB storage disks, in particular to a foldable USB storage disk device. Background Art

[0002] U disk is the abbreviation of USB (USB flash disk) disk, which is also called "U disk" according to homophony. U disk is a kind of flash memory, so it is sometimes called a flash disk. The biggest difference between U disk and hard disk is that it does not require a physical driver, plug and play, and its storage capacity far exceeds that of floppy disk, making it extremely easy to carry. U disk integrates disk storage technology, flash memory technology and universal serial bus technology. The USB port connects to the computer and is a channel for data input / output; the main control chip enables the computer to recognize the U disk as a removable disk and is the "brain" of the U disk; the U disk Flash chip saves data, and unlike the computer's memory, the data will not be lost even after a power outage; the PCB base plate connects the various components together and provides a platform for data processing.

[0003] Some traditional foldable USB flash drives mainly consist of a main body and a protective cover. The protective cover is rotated to cover the USB interface to protect it. After such devices are used for a long time, the connection between the protective cover and the USB flash drive is prone to wear due to long-term friction. Therefore, after long-term use, the protective cover is easily separated from the surface of the USB interface. For this reason, we propose a foldable storage USB flash drive device.
