Abstract
The utility model provides a laptop capable of being used as a USB interface mobile hard disk, which comprises a host machine part, a display screen and a USB interface part, wherein the interior of the host machine part is provided with two switch controlling modules which are connected with a chip set and an interface switching module which is connected between the two switch controlling modules; the two switch controlling modules respectively control states of a hard disc of the laptop and the USB interface, and thus, the function of the laptop as known application or the USB mobile hard disc is realized; the interface switching module switches an interface of the hard disc of the laptop to a modular circuit of the USB interface, and an internal modular circuit is connected with an external device through the USB interface. By use of the utility model, the utility model can regard the laptop as the USB mobile hard disc to use through the USB interface in the state of not starting up and realizes data exchange with the connected external device.
Description
Technical field
The utility model relates to a kind of notebook computer that can be used as the USB interface portable hard drive.
Background technology
The development of society, the progress of science and technology, PC has become the necessary articles for use of daily life, and notebook computer more becomes the main flow in market in recent years, and information interchange is more and more frequent, and the information interchange amount is also increasing.
For large-capacity data information, generally the mode that is connected to this machine by network is transmitted data, in addition because advantage such as support hot plug, plug and play, transmission speed that USB interface itself had be fast, also occur many jumbo USB movable storage devices in recent years, also reached the purpose of exchanges data by the mode that shifts storage.But still to store on the PC at last or will be connected on the PC and could handle data, the Network Transmission mode is subject to the network bandwidth simultaneously, transmission speed is slower than the transmission speed of USB interface, high capacity USB movable storage device exists expensive shortcoming again, and also will carry a mobile storage when carrying notebook computer and also cause inconvenience in the work neutralization study.Shifting storage or Network Transmission mode in addition must all start shooting and be just can finish after entering operating system in both sides' PC, disagrees with the simple and efficient theory efficiently that present society is advocated, and has restricted speed of information exchange.
The utility model content
A purpose of the present utility model provides a kind of notebook computer that can be used as the USB interface portable hard drive, do not open the notebook computer primary power or do not connecing external power source, or even under the situation of dead battery, this notebook as a USB portable hard drive with the equal capacity of described notebook hard disk.
Another purpose of the present utility model is in these cases, makes this notebook computer carry out data with another computer that has USB interface and exchanges, and by the computer that links to each other the data on the described notebook are handled.
The purpose of this utility model is achieved by following technical proposals.
The notebook computer that can be used as the USB interface portable hard drive of the present utility model comprises: a host machine part, in be provided with a hard disk; One motherboard; Two switch control modules and an interface modular converter of linking to each other with chipset, the chipset of described switch control module one and motherboard, computer hard disc and interface modular converter are electrically connected, two different conditions controlling that described notebook computer hard disk is used as routine or use as the USB portable hard drive, described switch control module two and usb circuit, motherboard chipset and interface modular converter are connected, connecting interface when the routine application of control USB interface or notebook computer hard disk use as the USB portable hard drive, described interface modular converter is connected between two switch control modules, and the notebook computer hard-disk interface is converted to USB interface; One display screen, this display screen is connected in rotating mode with host machine part; And USB interface, be connected with other computer by this USB interface, realize directly and the exchanges data of other computer.
Description of drawings
Figure 1 shows that the utility model can be used as the stereographic map of the notebook computer embodiment of USB interface portable hard drive.
Shown in Figure 2 is the notebook computer functional module connection diagram that the utility model can be used as the USB interface portable hard drive
Embodiment
See also Fig. 1 and Fig. 2, the notebook computer 1 that the utility model can be used as the USB interface portable hard drive comprises host machine part 2, USB interface 3 and display screen 4 compositions that are connected with rotary way with host machine part; Be provided with motherboard 6 and notebook computer hard disk 23 in the described host machine part 2, integrated switch control module 1, switch control module 2 25 and hard-disk interface change usb interface module 24 on motherboard 6; Switch control module 1 is connected to chipset 21 by the BUS1 interface, be connected to hard-disk interface by the BUS2 interface and change usb interface module 24, be connected to computer hard disc 23 by the BUS3 interface, hard-disk interface changes usb interface module 24 and links to each other with switch control module 2 25 by the BUS4 interface, switch control module 2 25 is connected to chipset by BUS5, while switch control module 2 25 and USB interface 3, USB interface 3 is connected to other computer 5 by the usb data line.
When described notebook computer normally enters system, switch control module 1 turn-offs BUS2 communication interface bus, computer hard disc 23 and hard-disk interface conversion this moment usb interface module 24 can not be communicated by letter again, and computer hard disc 23 and common notebook computer hard disk are without any difference; Switch control module 2 25 turn-offs BUS4 communication interface bus simultaneously, USB interface 3 and chipset 21 direct communications, and the USB interface 3 of this moment and the USB interface of common computer are without any difference.
When described notebook does not start shooting, do not connect under the situation of external power source or dead battery, switch control module 1 turn-offs the BUS1 communication interface, open the BUS2 communication interface simultaneously, switch control module 2 25 is BUS5 communication interface BUS OFF, open the BUS4 communication interface simultaneously, USB interface 3 is opened with the communication line of computer hard disc 23, and the function of the USB interface 3 of this moment is the interfaces as the USB interface portable hard drive.
In addition, the switching of switch control module also can reach the different conditions that switches described notebook computer hard disk and USB interface by the keyswitch that is connected to the casing outside.
The above only is preferred embodiment of the present utility model; yet be not to be defined in scope of the present utility model; every personnel that are familiar with the industry also can make all equivalent changes and improvements under the prerequisite of spirit of the present utility model, the utility model protection domain is as the criterion with claim institute confining spectrum.
