Description
Technical field
The utility model relates to computer fittings technical field, in particular to a kind of anti-loss USB flash disk.
Background technique
People are commonly encountered the case where losing USB flash disk when using USB flash disk.In the prior art, about the anti-patent for losing U disk
Or product, both for forget extract USB flash disk the case where.And many times under, often encounter, USB flash disk is extracted, but forgets band
The case where walking brings inconvenience to the work and life of people.
Utility model content
The utility model proposes a kind of anti-loss USB flash disks, and people can be reminded to take away the USB flash disk extracted, and are the work of people
It is convenient to provide with life.
What the technical solution of the utility model was realized in：
A kind of anti-loss USB flash disk, including master controller, usb interface module, indicator light, write-protect module, flash memory and clock mould
Block；It further include switch, charging detecting model, rechargeable battery and buzzer, the switch, buzzer and charging detecting model difference
It is connect with master controller, the rechargeable battery is connect with switch and charging detecting model respectively.
Further technical solution, the rechargeable battery are button rechargeable battery.
Further technical solution further includes double sudden strain of a muscle LED light, and double LED light of dodging are connect with master controller.
Further technical solution further includes charge control module, the charge control module respectively with master controller and
Rechargeable battery connection.
Further technical solution, the model CH375 of the master controller.
The utility model has the beneficial effects that：In USB flash disk in use, the utility model detects button by charging detecting model
The voltage of rechargeable battery, master controller control charge control module according to the voltage of button rechargeable battery as the confession of button rechargeable battery
Electricity；After USB flash disk is extracted, button rechargeable battery is that whole system is powered, and clock module starts timing, when reaching regular hour threshold
When value, main controller controls buzzer and double LED light of dodging work, and sound-light alarm are carried out, so that people be reminded to take away USB flash disk.This reality
It is simple with new structure, it is easy to accomplish, significant effect effectively prevents people to lose USB flash disk.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the systematic schematic diagram of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, the utility model proposes a kind of anti-loss USB flash disk, including master controller, usb interface module, instruction
Lamp, write-protect module, flash memory and clock module；Usb interface module, indicator light, write-protect module, flash memory and clock module difference
It is connect with master controller.The model CH375 of master controller.It further include switch, charging detecting model, rechargeable battery and buzzing
Device, the switch, buzzer and charging detecting model are connect with master controller respectively, the button rechargeable battery respectively with switch
It is connected with charging detecting model.The rechargeable battery is button rechargeable battery, model CR1220 or LIR2032.Further include
Charge control module, the charge control module are connect with master controller and rechargeable battery respectively.It further include double sudden strain of a muscle LED lamps, institute
It states double LED light of dodging to connect with master controller, double sudden strain of a muscle LED light are red green LED light.Indicator light and double sudden strain of a muscle LED light are mountable in shell
On, shell can also be set to transparent outer cover, indicator light and double LED lamps that dodge are integrated on circuit boards, from transparent outer cover, that is, considerable
Observe indicator light and double working conditions for dodging LED light.
Charging detecting model is used to detect the voltage of button rechargeable battery, and information of voltage is sent to master controller, with
Master controller is set to control the charging of charge control module button rechargeable battery according to the voltage of button rechargeable battery.It is carrying out specifically
When implementation, since the charging voltage of button rechargeable battery is smaller, charging current also very little, charge control module can by with knob
Rechargeable battery series resistance and capacitor are detained to achieve the purpose that current limliting.
The principles of the present invention are：The anti-loss USB flash disk of the utility model is when on the USB interface for being inserted into computer, master control
Device control charging detecting model processed detects button rechargeable battery both end voltage, when button charged battery voltage deficiency, main control
It is that button is rechargeable battery powered that device, which controls charge control module, until button rechargeable battery charging complete.When people have used U
Disk, and by USB flash disk extract USB interface on when, button rechargeable battery be entire circuit power, clock module starts timing at this time, arrives
Up to after a certain period of time, main controller controls buzzer is alarmed, and is controlled double LED light of dodging and flashed, and is helped and is reminded people
Find USB flash disk and take away USB flash disk.After people find USB flash disk, on & off switch is pressed, button rechargeable battery stops being that master controller supplies
Electricity, buzzer and double LED light of dodging stop working.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
