Problems solved by technology

[0002] As a common USB plug-in device, USB flash drive (U disk) can be divided into write-protected U disk and ordinary U disk according to whether it has write protection function. Compared with ordinary U disk, write-protected U disk has stronger anti-virus, Anti-misoperation features, but the current write-protected U disk generally uses a mechanical switch to switch between protection mode and normal mode, which is inconvenient to operate and has a limited life

Abstract

The invention provides a USB device with a switch device. The USB device with the switch device comprises a shell, a USB plug, a mass memory of a master controller, a gesture sensor and a sensing controller. The gesture sensor is electrically connected with the sensing controller. The sensing controller is also electrically connected with the mass memory and the USB plug. The USB plug is used for supplying a working voltage to the sensing controller. The sensing controller is used for receiving a sensing signal from the gesture sensor and outputting a corresponding control signal to the mass memory so that the writable state of the mass memory can be controlled correspondingly. The USB device with the switch device can realize switch between working states.

Description

technical field [0001] The invention relates to a USB device, in particular to a USB device with a switching device. Background technique [0002] As a common USB plug-in device, USB flash drive (U disk) can be divided into write-protected U disk and ordinary U disk according to whether it has write protection function. Compared with ordinary U disk, write-protected U disk has stronger anti-virus, Anti-misoperation features, but the current write-protected U disk generally uses a mechanical switch to switch between the protection mode and the normal mode, which is inconvenient to operate and has a limited life. Contents of the invention [0003] In view of the above, it is necessary to provide a USB device that does not use a mechanical switch to switch between the protection mode and the normal mode. [0004] A USB device with a switching device provided by the present invention includes: a casing, a USB plug, a main controller and a large-capacity storage, and the USB p...
