Description

The activation protection electrical lock apparatus of notebook computer

Technical field

The utility model is the safety device about a kind of notebook computer, is meant a kind of activation protection electrical lock apparatus of notebook computer especially.

Background technology

Computer equipment generally uses in various industrial occasions, commercial situations, office, teaching environment even domestic environment.In various application scenarios, major part is to use desktop computer to carry out required function.But in stressing the application scenario of high maneuverability (office that for example takes action, professional contact are showed, the technician of motor-driven support etc.), portable computer or to claim that notebook computer can meet the user required then.

Though notebook computer has good motor-driven Portable function, this notebook computer generally be belong to the exclusive instrument of individual's uses could use or essential through the authorized person, so the activation of its equipment, use, reach data secrecy provision particular importance.The secrecy provision aspect of common notebook computer mostly is to focus on mechanism's aspect, for example comes the activation and the use of this notebook computer of control with mechanisms such as tapered end or snap closes.The traditional mechanism of this type secret aspect, need be used the purpose that key just can reach unlatching/snap close.If user oneself leaves behind or loses this key, promptly can't this notebook computer of open operation.Moreover key is backed up easily, and the personage who also is easy to be familiar with lock head structure opens easily.So activation and use that the mode of maintaining secrecy with mechanism's locking in known technology is come the control notebook computer obviously are not inconsistent real demand.

Therefore, be necessary to give control in fact, to answer the demand of reality at the activation and the use of aforementioned notebook computer.

Summary of the invention

Therefore, the fundamental purpose of the utility model promptly provides a kind of activation protective device of notebook computer, activation in order to the control notebook computer, the user is only behind the correct password of input, could activate this notebook computer smoothly, with control without permission the person activate and use this notebook computer, guarantee the security of this notebook computer inside information.

Another purpose of the utility model provides a kind of electrical lock apparatus of notebook computer, it adopts the mode of electronic settings and electronic signal unlatching, whether can be allowed to activate this notebook computer with decision, because this electrical lock apparatus is to see through user's contact point contact or input password in the mode of button input, with unlocking electronic lock, so the disappearance that can avoid the traditional mechanical formula to unblank.

A purpose again of the utility model provides a kind of notebook computer electrical lock apparatus with preferable security protection effect, its electronic lock is except deciding with the password verification mode the whether unlatching of notebook computer, the user also can arbitrarily reset the password of electronic lock, and so effectively control notebook computer exclusive used and the security of enhancing data protection.

In order to reach above-mentioned purpose, in the specific embodiment of the utility model, be on a notebook computer, to be laid with a plurality of contact points, each contact point is connected in via signal connecting line respectively in the password identification control circuit, the contact point that contacts or input via this password identification control circuit identification user with the password that preestablishes correct after, send one by this password identification control circuit and allow the computer activation signal, activate to allow the normal of this notebook computer.In another embodiment of the utility model, also each contact point can be replaced with cipher inputting keyboard, this cipher inputting keyboard is connected to this password identification control circuit via winding displacement.
