Abstract
The utility model discloses a U flash disk, belonging to the field of U flash disks. The U flash disk comprises a PCB (Printed Circuit Board) on which electronic components are welded, a USB (Universal Serial Bus) interface to be connected with a computer, and a Flash chip used for storing data, and further comprises a microcontroller, a display module, a power supply and a display switch, wherein the Flash chip and the display module are both connected with the microcontroller, and the display switch is used for starting the display module to display surplus capacity. By the U flash disk, people can check the surplus capacity of the U flash disk at any time. The U flash disk is reasonable in design and provides the convenience to a user.
Description
Technical field
The utility model relates to a kind of USB flash disk, belongs to the USB flash disk field.
Background technology
USB flash disk is the miniature high power capacity movable storage device that people commonly use, and it can carry out exchanges data by USB interface and computer, and plug and play, improved office efficiency greatly.
The main flow capacity of USB flash disk is in 8G～16G left and right at present, max cap. has reached 1T, the memory capacity of super large is provided convenience to people's working and learning, but USB flash disk only could be checked on computers residual capacity when connecting computer, otherwise people can't be known residual capacity, this has brought inconvenience to the use of USB flash disk, has also reduced the service efficiency of USB flash disk simultaneously.
The utility model content
The purpose of this utility model is: propose a kind of USB flash disk that can show residual capacity.
This USB flash disk comprises pcb board for welding electronic component, for the USB interface that connects computer with for storing the Flash chip of data, also comprise microcontroller, display module, power supply and display switch, described Flash chip all is connected with microcontroller with display module, and display switch is for starting display module.
Further, this USB flash disk also comprises pilot lamp, and described pilot lamp is connected with microcontroller.
Preferably, described display module adopts the LCD screen.
Preferably, described display switch adopts Piezoelectric switches.
Technique effect:
1, make USB flash disk can check at any time residual capacity, provide convenience to user's use.
2, practical function, reasonable in design, easy to use, can not hinder the normal use of USB flash disk yet.
3, additionally do not increase the volume of USB flash disk, realize that cost is low, there are desirable market outlook.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Number in the figure title: 1, pcb board; 2, USB interface; 3, Flash chip; 4, microcontroller; 5, display module; 6, pilot lamp; 7, power supply.
Embodiment
Below the utility model is described in further detail.
The structure of the utility model USB flash disk as shown in Figure 1, mainly comprise pcb board 1 for welding electronic component, for the USB interface 2 that connects computer, for storing the Flash chip 3 of data, also comprise microcontroller 4, display module 5, pilot lamp 6, power supply 7 and display switch, described Flash chip 3, display module 5 and pilot lamp 6 all are connected with microcontroller 4, and display switch is for starting display module 5.
Similar with common U disk, pcb board 1 is rectangle, and all electronic devices and components all are welded on this plate, and the Type-A USB joint of USB interface 2 employing standards is welded in an end of pcb board 1, for directly inserting the USB mouth of computer; But the capacity flexible design of Flash chip 3, adopt the 16G capacity here; Microcontroller 4 adopts monolithic MCU chip, and, as USB main control chip (using the USB3.0 standard), its peripheral circuit comprises crystal oscillator, Chip-R and patch capacitor; Display module 5 adopts small-sized LCD backlight screen; Pilot lamp 6 adopts paster LED, and it lights when USB flash disk connects computer; Power supply 7 adopts a SR512SW button cell, temporary source when it does not connect computer as USB flash disk; Display switch adopts Piezoelectric switches, and it acts on display module 5 by microcontroller 4.
This USB flash disk adopts ABS plastic or metal as shell, and pilot lamp is located near the USB interface place, and Piezoelectric switches is located at the USB flash disk middle part, and the LCD screen is located at the USB flash disk afterbody, and the both sides of USB flash disk are provided with and increase the striped that rubs.When the user need to check the USB flash disk residual capacity, only need click Piezoelectric switches, the LCD screen starts backlight, and microcontroller obtains the residual capacity of Flash chip and is presented on the LCD screen, automatically close demonstration after showing a period of time (as 5 seconds), to save battery electric quantity.
