Abstract
The utility model relates to the USB flash disk with Presentation Function, it comprises housing and is arranged on the circuit board in described housing, one bistable LCD is also installed in described housing, on described housing, offers one for exposing the window of described bistable LCD.Utilize the characteristic of bistable LCD, also can displaying contents be retained and be shown without power supply, only, in the time wiping displaying contents, just need energising, reach energy-saving and cost-reducing effect.
Description
Technical field
The utility model relates to USB flash disk structure.
Background technology
At present, the USB flash disk with Presentation Function generally adopts LCDs, and after USB flash disk is connected with computer, LCDs is also lighted, and shows some information in USB flash disk, as capacity.But when after USB flash disk and computer disconnection, LCDs is just extinguished at once, can not work on.
Along with people, to memory device more and more stronger according to patience time, people are also more and more diversified, personalized to the demand of memory device.In numerous individual demands of people, be the strongest to the demonstration demand of memory device.Main point of two parts in displaying contents, a part is to need stored prod dynamically to show the storage synopsis of its inside, as information such as the states of the quantity of storage file, size and storage space; It is to wish that stored prod shows fixing mark that another part shows, as the Logo flag information of individual name, company etc.
Obviously, current USB flash disk can not meet the demonstration requirement of another part.
Utility model content
The purpose of this utility model is to propose a kind of USB flash disk with Presentation Function, and it can solve the problem that still can show information after power-off.
In order to achieve the above object, the technical scheme that the utility model adopts is as follows:
Have the USB flash disk of Presentation Function, it comprises housing and is arranged on the circuit board in described housing, and a bistable LCD is also installed in described housing, offers one for exposing the window of described bistable LCD on described housing.
Preferably, be integrated with USB chip and the driving circuit for driving bistable LCD to reset on described circuit board, USB chip provides operating voltage for described driving circuit.Further preferred, on described housing, be also provided with one for controlling the reset key of described drive circuit works.
Preferably, on described window, cover and be provided with one transparency protected.
The utlity model has following beneficial effect:
Utilize the characteristic of bistable LCD, also can displaying contents be retained and be shown without power supply, only, in the time wiping displaying contents, just need energising, reach energy-saving and cost-reducing effect.
Brief description of the drawings
Fig. 1 is the package assembly schematic diagram of the USB flash disk with Presentation Function of the utility model preferred embodiment;
Fig. 2 is the fractionation structural representation of the USB flash disk with Presentation Function of the utility model preferred embodiment.
Reference numeral: 1, housing; 101, upper casing; 102, lower casing; 103, right shell; 104, left shell; 105, baffle plate; 2, window; 3, circuit board; 4, bistable LCD; 5, collets; 6, transparency protected.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further.
Shown in Fig. 1 and Fig. 2, a kind of USB flash disk with Presentation Function, it comprises housing 1 and is arranged on the circuit board 3 in described housing 1, and a bistable LCD 4 is also installed in described housing 1, offers one for exposing the window 2 of described bistable LCD 4 on described housing 1.
On described circuit board 3, be integrated with USB chip and the driving circuit for driving bistable LCD 4 to reset, USB chip provides operating voltage for described driving circuit.On described housing 1, be also provided with one for controlling the reset key (figure does not draw) of described drive circuit works.
On described window 2, cover and be provided with one transparency protected 6, to prevent, to bistable LCD 4 touching that meets accident, causing figure or pattern on bistable LCD 4 destroyed.
As shown in Figure 2, be the concrete inner structure of the present embodiment.Housing 1 is connected and composed by upper casing 101, lower casing 102, right shell 103, left shell 104, thereby formation one has the housing 1 of accommodation space, and left shell 104 is for the protection of the USB interface on circuit board 3, and the left end on left shell 104 is also used baffle plate 105 cappings.Between circuit board 3 and bistable LCD 4, be also provided with collets 5.Window 2 is arranged on upper casing 101.
When use, transparency protected 6 is taken off, the paddling on bistable LCD 4 with writing pencil or other rigid posts, leaves paddling vestige, and then loads onto transparency protected 6.When normal use USB flash disk, left shell 104 can be taken off, expose USB interface, USB interface is inserted to computer, USB chip obtains electric work.When need to wipe on bistable LCD 4 vestige time, as long as obtain under the state of electric work at USB chip, press reset key, can make driving circuit export a reset wave to bistable LCD 4, the vestige on bistable LCD 4 is removed.
For a person skilled in the art, can be according to technical scheme described above and design, make other various corresponding changes and distortion, and these all changes and distortion all should belong to the protection domain of the utility model claim within.
