Embodiment
Referring to Fig. 2, a kind of unlocking mechanism 18, it comprises handle 11, at least one back-moving spring (not shown), tooth bar 12, gear type electrode axis 15, electromagnet 13 and mechanism's state detection unit 14, gears engaged on this tooth bar 12 and the gear type electrode axis 15, this at least one back-moving spring is positioned at handle 11 inboards, wherein, this electromagnet 13 is a bistable electro-magnet, and described handle 11 is positioned on the extended line of tooth bar 12 long axis directions one end.
Referring to Fig. 3, a kind of Intelligent key that uses above-mentioned unlocking mechanism 18, a kind of Intelligent key, it comprises a shell 16, ID coding 19, control unit (not shown) and a unlocking mechanism, this shell 16 is made up of cover assembly and base assembly; Described control unit and described unlocking mechanism 18 are positioned at described shell 16, and the handle in the described unlocking mechanism 18 11 is positioned at a side of described Intelligent key shell 16; On the corresponding side of described shell and above-mentioned side, also be provided with a recess, hold, be convenient to the application of force for finger forceps.Described ID coding 19 is installed in an end of described shell, one side at the small electrode that is provided with of described ID coding 19; This unlocking mechanism 18 comprises handle 11, at least one back-moving spring (not shown), tooth bar 12, electromagnet 13, electromagnet turnover panel 131, rotation axis 132, gear type electrode axis 15 and mechanism's state detection unit 14, gears engaged on this tooth bar 12 and the gear type electrode axis 15, this electromagnet 13, mechanism's state detection unit 14 and ID coding 19 all is electrically connected with control unit, this electromagnet turnover panel moving axis that can rotate rotates, this at least one back-moving spring is positioned at the handle inboard, this electromagnet 13 is a bistable electro-magnet, and described handle is positioned on the extended line of tooth bar long axis direction one end.
Briefly introduce Intelligent key below and open/course of work of blocking mechanism: when unblanking, at first by ID coding 19 a detection coding, after checking correct coding, signal is passed to control unit, 13 adhesives of control unit control electromagnet, electromagnet turnover panel 131 moving axis 132 rotation (pressing clockwise direction among Fig. 2) that rotates, this moment, handle 11 can be operated, and because the rotation of electromagnet turnover panel 131, electromagnet turnover panel 131 will limit handle 11 and reset when handle 11 moves a certain distance, and setpoint distance is about 2mm in the present embodiment.After lockset was opened, mechanism's state detection unit 14 passed to control unit with signal, 13 adhesives of control unit control electromagnet, and electromagnet turnover panel 131 moving axis 132 rotations (press among Fig. 2 counterclockwise) that rotate, handle 11 can reset at this moment.When handle 11 allows to be operated, moment transmission mechanism 12 is directly transmitted and acted on to the power that finger puts on the handle 11, because the gears engaged on moment transmission mechanism 12 and the gear type electrode axis 15, tooth bar 12 stressed and motion turns clockwise gear type electrode axis 15, and lockset is opened; Back-moving spring is executed restoring force along the tooth bar long axis direction to handle 11 when lockset is opened back or locking, and gear type electrode axis 15 is rotated counterclockwise, and lock knob resets, and this moment, Intelligent key can take off from lockset.
The Intelligent key unlocking mechanism is as the most important execution unit of Intelligent key.Whether the quality of its performance mainly contains the index of the following aspects:
1. the moment of unblanking of mechanism;
2. the power consumption of unlocking mechanism;
3. the profile of unlocking mechanism and volume size.
The size of the moment of unblanking has determined that directly this mechanism is fit to the lockset type of operation and the maximum lockset corrosion degree of permission, usually the moment of unblanking is big more, its performance of unblanking is just good more, the power consumption of unblanking is the principal element that influences Intelligent key overall performance electrical performance index, the power consumption of unblanking is more little, unlocking times will correspondingly increase but Intelligent key once charges, and therefore to reduce the electric quantity consumption of unblanking most important as far as possible; The profile of unlocking mechanism and volume need to determine according to the profile of Intelligent key and in-built requirement, will consider anthroposomatology aspect factor to the full extent simultaneously.
The utility model adopts pincers to hold the formula unlocking mechanism, and this Intelligent key unlocking mechanism is held formula handle 11, tooth bar 12, bistable electro-magnet 13 and mechanism's state detection unit 14 etc. by pincers and partly formed.This mechanism's detecting unit 14 comprises lockset open detection unit and key reset detection unit.Aspect the moment of unblanking: compare with other unlocking mechanism, under the prerequisite that does not increase gear moment transmission mechanism torque transmitting ratio, hold the mode of unblanking by employing and increase the moment that human body can apply, thereby increase substantially the moment of unblanking of mechanism, consider anthroposomatology aspect factor simultaneously to the full extent.By evidence, the maximum moment of unblanking can reach 1.1Nm, is to push away more than a times of the formula of turning round and push button unlocking mechanism.The power consumption aspect of unblanking: traditional unlocking mechanism all adopts the effect of monostable electromagnetic mechanism to open/the locking performance element, all needs continuously the energising several seconds just can finish once in operating process and opens/lock operation, and power consumption is at the 1000mAS order of magnitude.Pincers are held the formula unlocking mechanism and are adopted bistable electro-magnet as opening/the locking performance element originally, the action that makes out/close switches in the 20ms and just can finish, and can keep operate condition for a long time, thus the power consumption index of this mechanism is reduced greatly, be about about 30mAS.Aspect mechanism's profile and volume: owing to adopt horizontal side to unblank to force way, the thickness of mechanism is reduced greatly, can be Intelligent key and reserve certain space and be used to arrange other equipment (as: LCD display, keyboard, loudspeaker etc.), help reducing the key overall dimensions.
The utility model also has some other distortion or improvement, and handle 11 also can be integral type mechanism with moment transmission mechanism 12; Manner between cover assembly and the base assembly also has multiple, as screw connection etc.If those skilled in the art are subjected to the change or the improvement of the conspicuous unsubstantiality that inspiration of the present utility model makes, all belong to the protection range of the utility model claims.
