Most key sheets in the existing computer keys are in a convex column shape, a sheet shape or a strip shape. In practical application, most of the key sheet actuating mechanisms adopt fixed structures, namely the key sheet cannot be retracted, and the key sheet is exposed in the mode and is easy to wear and even damage due to falling and collision; or the key sheet is retracted in a folding mode, and the key sheet is ejected out easily due to misoperation when the mechanical pressing operation is adopted in the folding mode.

The authorization mechanism adopts direct drive of magnetic force, solenoid, motor and the like as main authorization mode, and the driving element in the direct drive mode is directly and continuously contacted with the driven element, so that the anti-theft performance is low and the anti-theft mechanism is easy to crack. If the driving element is in misoperation or external interference, the problem of false authorization of the unlocking mechanism is easily caused.

An electromagnetic intelligent identification key for a magnetic control lock comprises: the key comprises a key body, a key rod, a magnetic control rod, a propelling device, a linkage rod and an intelligent circuit device; the key rod is inserted into one end of the key body and extends out of the key body, the key rod is hollow, the inside of the key rod is matched with the magnetic control rod, the magnetic control rod is controlled to stretch out and draw back by the linkage rod, and the driving device in the key body controls the linkage rod to drive the magnetic control rod to stretch out and draw back. The scheme does not solve the problem of exposing the key sheet, and directly drives the magnetic control rod to stretch out and draw back through the driving device, so that misoperation of the magnetic control rod is easy to occur, and the safety is lower.

The unlocking key hiding structure with the folding function comprises a key, a key handle, a rotating block, a resetting block, a clamping block and a resetting torsion spring; through the rotating block, the spring returns, and the fixture block realizes that the key is locked in the key handle when not needing to be unlocked, and the key is released from the key handle when being unlocked. The scheme is used for applying the key sheet rotating and folding technology to the unlocking key, has a simple structure and is convenient to use, but the problem that the key is ejected out by the misoperation button is not solved yet.

The difference from the first embodiment is that the specific structure of the transmission member 51 is different.

As shown in fig. 16 and 17, in the present embodiment, the transmission member 51 is rotatably provided in the housing 10, and the outer wall thereof is provided at an upper portion thereof with a spiral track and at another portion thereof without a spiral track, so that a spiral section and a non-spiral section are formed at the peripheral side of the transmission member 51, and as the transmission member 51 rotates, the spiral section and the non-spiral section alternately oppose the projecting end to be respectively press-fitted and to be avoidance-fitted with the projecting end 431. Specifically, when the unlocking piece 20 is located at the initial retracted position, the protruding end 431 is aligned with the non-spiral section and is circumferentially staggered with the spiral track, at this time, on one hand, the movement of the spiral track does not affect the protruding end 431, so that the authorized magnetic piece 41 is kept at the unauthorized position, on the other hand, the spiral track itself does not interfere with the subsequent movement of the protruding end 431, so that when the unlocking piece 20 moves to the working position, the protruding end 431 can smoothly extend into the rotation range of the spiral track; when the unlocking piece 20 is located at the working position, the protruding end 431 is located at the end of the spiral track and can extend into the rotation range of the spiral track so as to be in extrusion fit with the spiral track, and at the moment, only the transmission piece 51 needs to be driven to rotate, and the protruding end 431 can be extruded due to the spiral shape of the spiral track, so that the authorization magnetic piece 41 moves towards the authorization position; when resetting, the driving member 51 rotates reversely, the extending end 431 is always abutted against the spiral track under the action of the resetting member 60 until the extending end 431 moves to the end of the spiral track, the extending end 431 is aligned with the non-spiral section again, and the unlocking piece 20 can move back to the retracted position smoothly.

In this embodiment, the authorization assembly 50 further includes an authorization driving member 52, where the authorization driving member 52 is a motor and is in driving connection with the driving member 51, so as to drive the driving member 51 to rotate, and in this embodiment, the driving member 51 is configured in a column shape, one end of the driving member is connected with the authorization driving member 52 through a D-shaped opening and the like, and the rotation axis of the authorization driving member 52, that is, the rotation axis of the driving member 51 is parallel to the movement track line of the unlocking plate 20, so that the spiral track on the peripheral side of the driving member 51 can be matched with the protruding end 431. Of course, other modes than the above arrangement, such as the specific rotation mode, the structural shape, etc. of the transmission member 51 may be adopted as required, as long as the movement of the authorization magnetic member 41 can be achieved by intermittent cooperation with the protruding end 431.

Optionally, a limiting structure may be further disposed on the transmission member 51, and the limiting structure is matched with a corresponding portion on the housing 10 in a stop manner, so as to control the rotation range of the transmission member 51.

The magnetic steel adopted by the authorization magnetic member 41, the transmission magnetic member 42 and the transmission member 51 in this embodiment is, of course, other types of magnetic members may be selected as required.

It should be noted that, in the above embodiments, a plurality refers to at least two.

1. the problem of lower safety of a computer key in the prior art is solved;

2. the unlocking plate component is driven to move in a telescopic mode through the gear and the rack, so that the influence of external misoperation on the unlocking mechanism is effectively prevented, the unlocking plate component is prevented from being ejected out when the unlocking key is in a non-working state, and the carrying safety and the using convenience of the unlocking key are improved;

3. the interference of external and internal action parts can be avoided through the authorization mode of the authorization component, meanwhile, the condition that authorization is invalid due to misoperation of the authorization component is avoided, and the reliability of authorization is ensured;

4. the authorization component and the magnetic component are matched through magnetic force action or mechanical stirring action, so that the structure is simple, and the safety and the reliability are realized.
