Abstract
The utility model relates to a novel intelligent U disk, which comprises a hollow shell provided with an opening at one end and a cover body matched with the shell, wherein the opening end of the shell is provided with a USB interface, the shell is internally provided with a circuit board and a storage chip connected with the circuit board, the circuit board is provided with a delayed alarm circuit, the USB interface in the shell is provided with a female metal contact piece connected with the delayed alarm circuit, and the cover body is provided with a male metal contact piece. The novel intelligent U disk provided by the utility model is simple in structure and reasonable and compact in design. When the female metal contact piece is tightly contacted with the male metal contact piece, that is, when the U disk is not used, the delayed alarm circuit stays at an inactive state; when the U disk is used through the USB interface, the delayed alarm circuit stays at a semi-activated state; after a computer is turned off, the USB interface is powered off, and the delayed alarm circuit is powered by a storage battery to warn that the U disk is not taken down. The novel intelligent U disk is low in implementation cost, and has extremely high practical values.
Description
Technical field
The utility model relates to the technical field of USB flash disk, especially a kind of novel intelligent USB flash disk.
Background technology
In known technical field, USB flash disk is a kind of memory storage common in people's working and learning, because being subject to people, its efficient convenience, the performance that is easy to carry about with one welcome widely, in the use of reality, the student is after complete machine on the Public Computer Room of school institute, and always some student forgets and takes away USB flash disk, and USB flash disk is lost, easily cause unnecessary trouble, both lost property, easily lose again important learning materials.
The utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, a kind of efficiently delayed alarm formula easily USB flash disk is provided.
the technical scheme that its technical matters that solves the utility model adopts is: a kind of novel intelligent USB flash disk, comprise the housing with an end opening and hollow and the lid that matches with housing, open end at described housing is provided with USB interface, the storage chip that is provided with circuit board and with circuit board, is connected in described housing, be provided with the delayed alarm circuit on described circuit board, be provided with the mother metal contact chip that is connected with the delayed alarm circuit on the USB interface on described housing, be provided with public Metal Contact sheet on described lid, described mother metal contact chip and public Metal Contact sheet be close contact when housing and lid closure, be provided with the LED warning lamp that is electrically connected to the delayed alarm circuit on the outside surface of described housing.
Further, in order to improve the effect of caution, the utility model is provided with hummer on described delayed alarm circuit.
Further, in order to give the delayed alarm circuit supply, the utility model is provided with solar panel on described housing, and described solar panel is connected with circuit board by accumulator.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design and compact, when mother metal contact chip and public Metal Contact sheet close contact, be that USB flash disk is not while being used, the delayed alarm circuit is in closed condition, when by USB interface, using, the delayed alarm circuit is in half state of activation, after shut down of computer, the USB interface outage, delayed alarm this moment circuit is powered by accumulator, and the caution USB flash disk does not also take off, this programme implementation cost is cheap, has practical value.
