Therefore; Press at present and develop a kind of notebook computer; It need not start, can let outer computer directly read and copies the data in the notebook computer hard disk, offers convenience for the daily use notebook computer of user; Thereby improve user's work efficiency greatly, strengthen user's product use experience.

The utility model content

In view of this; The purpose of the utility model provides a kind of notebook computer with portable hard drive function, and it need not start, can let outer computer directly read and copies the data in the notebook computer hard disk; Offer convenience for the daily use notebook computer of user; Thereby improve user's work efficiency greatly, help strengthening notebook computer user's product use experience, be of great practical significance.

For this reason; The utility model provides a kind of notebook computer with portable hard drive function; Include the notebook mainboard, said notebook mainboard is provided with the central processor CPU master chip, and said CPU master chip is connected with at least one notebook computer hard disk; Each said notebook computer hard disk changes serial port circuit with a parallel port and is connected, and said parallel port is changeed serial port circuit and is connected with a usb interface module.

Wherein, said notebook computer hard disk is connected with a power driving circuit, and said power driving circuit is connected with said usb interface module.

Wherein, said notebook mainboard is provided with two general-purpose serial bus USB interface modules, and said CPU master chip is connected with said general-purpose serial bus USB interface module.

Technical scheme by above the utility model provides is visible, compared with prior art, and a kind of notebook computer that the utility model provides with portable hard drive function; It need not start; Can let outer computer directly read and copy the data in the notebook computer hard disk, offer convenience for the daily use notebook computer of user, thereby improve user's work efficiency greatly; Help strengthening notebook computer user's product use experience, be of great practical significance.

Description of drawings

Circuit structure block scheme when a kind of notebook computer with portable hard drive function that Fig. 1 provides for the utility model is connected with outer computer;

Among the figure, 10 is the notebook mainboard, and 11 is the central processor CPU master chip, and 12 is the general-purpose serial bus USB interface module, and 20 is the notebook computer hard disk, and 30 is power driving circuit, and 40 are parallel port commentaries on classics serial port circuit, and 50 is outer computer.

Embodiment

In order to make those skilled in the art person understand the utility model scheme better, the utility model is done further to specify below in conjunction with accompanying drawing and embodiment.

Referring to Fig. 1; The utility model provides a kind of notebook computer with portable hard drive function; Include notebook mainboard 10; Said notebook mainboard 10 is provided with central processor CPU master chip 11 and two general-purpose serial bus USB interface modules 12, and said CPU master chip 11 is connected with said general-purpose serial bus USB interface module 12.

In the utility model; Said CPU master chip 11 is connected with at least one notebook computer hard disk 20; Each said notebook computer hard disk 20 changes with parallel port respectively that serial port circuit 40 is changeed in serial port circuit 40 parallel ports, a power driving circuit 30 is connected; Said parallel port is changeed serial port circuit 40 parallel ports and is changeed serial port circuit 40 and be connected with same usb interface module 12 with power driving circuit 30, sets up data through the usb data line between said usb interface module 12 and the outer computer and is connected.

Need to prove that in the utility model, the usb interface module 12 that is provided with on the said notebook mainboard 10 is not limited to two shown in Figure 1, can also be a plurality of arbitrarily according to user's needs.Simultaneously, the said notebook computer hard disk 20 on the notebook is not limited to one shown in Figure 1, can also be a plurality of arbitrarily according to user's needs.

For the utility model; Can the data on the notebook computer hard disk 20 outwards be transmitted by two data passages; One of them data path is specially: need not the notebook computer start; Data on the notebook computer hard disk 20 are changeed serial port circuit 40 parallel ports through said parallel port and are changeed serial port circuit 40, realize that directly converting the serial ports form into by the parallel port outputs to usb interface module 12, pass through usb interface module 12 then to outer computer 50 output datas.Another data path is specially: keep original notebook computer data transfer path; Notebook is in open state; Data on the notebook computer hard disk 20 form the serial ports form to outer computer 50 outputs by notebook mainboard 10 through data-switching then with the output of parallel port form.

Need to prove; The notebook computer that the utility model provides is compared with existing notebook; Increased a parallel port and changeed serial port circuit 40 parallel ports commentaries on classics serial port circuit 40 and a power driving circuit 30, said parallel port is changeed serial port circuit 40 parallel ports commentaries on classics serial port circuit 40 and is connected with a usb interface module 12 with power driving circuit 30, and said notebook computer hard disk 20 changes with the parallel port respectively, and serial port circuit 40 is changeed in serial port circuit 40 parallel ports, power driving circuit 30 is connected; Therefore; Outer computer can be successively gives the notebook computer hard disk 20 power supplies through said usb interface module 12, power driving circuit 30, provides 20 work of notebook computer hard disk needed working current, meanwhile; After the running of notebook computer hard disk 20 operate as normal; Said parallel port commentaries on classics serial port circuit 40 can directly convert the data on the notebook computer hard disk 20 into the serial ports form by the parallel port and output to said usb interface module 12, passes through this usb interface module 12 then to outer computer 50 output datas, and notebook computer hard disk 20 has had the function of portable hard drive at this moment; It is equivalent to a removable hard disk; Therefore, the hard disk on the notebook computer that the utility model provides has had the function of portable hard drive, need not start the notebook computer hard disk is supplied power.

Certainly, the notebook computer for the utility model provides is in open state, and notebook mainboard 10 can be supplied power to notebook computer hard disk 20, and the data that can not have influence on the notebook computer hard disk 20 are outwards transmitted.Therefore; Information transmission between notebook computer hard disk 20 and the outer computer 50 is just by independent; And the read-write of notebook computer hard disk self; Still use the original circuit kit of notebook computer, the data on the notebook computer hard disk are read, edit and operation such as output through the CPU master chip.

For the utility model; Mirror notebook computer hard disk on it has the function of portable hard drive; Therefore can under the situation that notebook computer is not started shooting, the data in the notebook computer hard disk directly be transferred in the other computer of working through USB interface; On the contrary, also can the data in the computer of working directly be transferred in this notebook that does not have start through USB.

In sum, compared with prior art, a kind of notebook computer that the utility model provides with portable hard drive function; It need not start; Can let outer computer directly read and copy the data in the notebook computer hard disk, offer convenience for the daily use notebook computer of user, thereby improve user's work efficiency greatly; Help strengthening notebook computer user's product use experience, be of great practical significance.

The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
