Optionally, the unlocking mechanism further comprises a lock detection piece 120 and a coil 130, wherein the lock detection piece 120 is a hall element, and is positioned at one end of the shell 10 close to the lock cylinder and can be matched with magnetic steel in the lock cylinder in the unlocking process of the unlocking mechanism, so that the unlocking and locking state of the lock cylinder can be determined by detecting magnetic flux change, and the coil 130 is positioned at one end of the shell 10 close to the lock cylinder and can be used for supplying power, acquiring codes and communicating with the lock cylinder, so that the functions of confirming the identity of the lock cylinder, supplying power to the lock cylinder and the like are realized.
In addition, the unlocking mechanism may further be provided with a control component 140, where the control component 140 is electrically connected with the power-on components such as the lock plate driving member 40, the authorized motor 61, the control switch 110, the lock detecting member 120, the coil 130, and the like, and can control the actions of the components, and coordinate the movements of the components through the control system. For example, when the unlocking mechanism is inserted into the lock cylinder, the coil 130 performs identity authentication on the lock cylinder, the authentication controls the authorization component 60 to drive the magnetic component 50 to act so as to unlock the authorization marble of the lock cylinder through the rear control component 140, and after receiving the unlocking or locking instruction, the control component 140 controls the lock plate driving piece 40 to act so as to change the position of the unlocking piece component 20, and the like.
Alternatively, the housing 10 of the present embodiment is formed by butt-jointing a plurality of sub-components which are separately provided, and the sub-components are fixed together by screw connection, thereby facilitating the installation of the components into the housing 10. The housing 10 may form one or more semi-enclosed or fully enclosed receiving areas as desired to mount components within the receiving areas as desired.
It should be noted that, in the above embodiments, a plurality refers to at least two.
From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
1. the problem of poor safety of an authorization mechanism of a computer key in the prior art is solved;
2. Compared with the traditional solenoid driving mode, the motor driving mode is more accurate and convenient for controlling the movement stroke, the unlatching blade is effectively prevented from unlatching illegally in the non-working position, the problem that the solenoid is easy to cause impact authorization due to the structural characteristics is solved, and the safety of an authorization mechanism is improved;
3. The whole structure is compact, the control is convenient, and the miniaturization of products is facilitated;
4. The authorization shifting lever does not influence the magnetic assembly during locking, and the magnetic assembly is kept at an unauthorized position, so that interference of external and internal action parts is avoided, and the condition that the authorization assembly is invalid due to misoperation of the driving part is avoided;
5. the authorized action is reliable, and the situation that the unlocking key is an master key because of unauthorized unlocking is avoided;
6. and the authorization state is monitored by adopting a contact or non-contact detection mode, so that the security of the authorization component is improved.
It will be apparent that the embodiments described above are merely some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
