Abstract
The invention discloses a key with a power taking structure. The key is characterized by comprising a key main body, wherein the key main body is provided with a power taking circuit and a password memorizing chip; one end of the power taking circuit is provided with a power taking contact which is contacted with a power taking probe on a door lock; the other end of the circuit is electrically connected with the password memorizing chip; and the password memorizing chip is electrically connected with the key main body. The key is conducted with the lock to form a loop through the power taking circuit and the power taking contact on the key main body after being inserted into the lock which is matched with the key, and password detection and other subsequent unlocking steps are performed on the password memorizing chip arranged on the key main body by using conducted electric current.
Description
Technical field
The present invention relates to a kind of key, particularly a kind of key with the power taking structure.
Background technology
Be locked in and play important effect in the daily life work, it is mechanical that traditional lock body mostly is greatly, because the constraint of the physical space of lock core and key, size of key is subjected to congenital restriction.No matter take the how many kinds of way, all can only prolong the time of technical opening, can not accomplish complete precautionary technology unlatching at aspects such as structure, technology and finenesses.
Thereby promoting an electron-like door lock on the market, it occurs along with development of electronic technology, is that mechanical lock is incomparable at aspects such as the convenience of using, intelligent managements, therefore is used widely in some industries.Common in the market mainly is electronic locks such as magnetic card, IC-card, contactless card, Fingerprint Lock.But above-mentioned lockset or defectiveness, mistake identification: the fingerprint recognition accuracy is subjected to reading the restriction of precision, humidity, technology such as dirty and environmental factor, can not reach 100%.The situation that can't discern also can take place because of demagnetization, kinking, scratch, service factor such as dirty in tradition magnetic card, IC-card; Transreplication: fingerprint duplication, contactless card duplicate, and have been the generalized situations that does not need the professional and technical personnel just can realize, have brought great potential safety hazard for the application of electric lockset.
Be directed to this, released a kind of electric lockset on the market, they mainly partly are made up of frame for movement part and electronic structure, frame for movement part and traditional mechanical lock are similar, include elements such as lock core, lock gall, pellet shot from a slingshot, the electronic structure part then includes elements such as electromagnetism components and parts (as the electronics pellet shot from a slingshot), control circuit and power supply, matches with frame for movement, as the driving of frame for movement.This is locked under the normal state is that circuit disconnects, thereby, need design a kind of can with the key of phase-locked conducting, realize that by the electric current after the conducting password detects and other step of unblanking.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of key with the power taking structure, can lock conducting with this after this key inserts in the lock that matches with it and form the loop, realize that by the electric current after the conducting password detects and other step of unblanking.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of key of power taking structure, it is characterized in that: comprise the key main body, the key main body is provided with power-supply circuit and password storage chip, one end of this power-supply circuit be provided with can with the contacted power taking contact of popping one's head in of the power taking on the door lock, the other end of this circuit and password storage chip electrically connect, and this password storage chip and the electric connection of key main body.
Described key main body comprises the shank of the key and can insert key bit in the lockhole, and the shank of the key is provided with installing hole, and key bit is provided with the mounting groove that links to each other with installing hole, and described password storage chip is arranged at installing hole, and described power-supply circuit is arranged in the mounting groove.
Described power-supply circuit comprises insulating slab and is arranged at conductive layer on the insulating slab, is provided with the gap between described mounting groove sidewall and conductive layer.
The invention has the beneficial effects as follows: can realize the password storage chip that is arranged on the key main body is carried out password detection and subsequent other step of unblanking by the electric current after the conducting by being arranged at power-supply circuit and power taking contact and this lock conducting formation loop on key main body and the key main body after this key inserts in the lock that matches with it.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is a front schematic view of the present invention.
The specific embodiment
With reference to Fig. 1, the invention discloses a kind of key of power taking structure, comprise key main body 1, key main body 1 is provided with power-supply circuit 2 and password storage chip 3, one end of this power-supply circuit 2 be provided with can with the contacted power taking contact 4 of popping one's head in of the power taking on the door lock, the other end of this circuit and password storage chip 3 electrically connect, and this password storage chip 3 electrically connects with key main body 1.
As shown in the figure, key main body 1 comprises the shank of the key 5 and can insert the interior key bit 6 of lockhole, in order not take up room, the shank of the key 5 is provided with installing hole 7, key bit 6 is provided with the mounting groove that links to each other with installing hole 7, described password storage chip 3 is arranged at installing hole 7, and described power-supply circuit 2 is arranged in the mounting groove.Further, directly contact the formation short circuit with key main body 1 in order to prevent power-supply circuit 2, power-supply circuit 2 comprises insulating slab and is arranged at conductive layer on the insulating slab that insulating slab is fixed at the bottom of the mounting groove, is provided with the gap between described mounting groove sidewall and conductive layer.
Operating principle of the present invention is as follows: this key inserts in the lock that matches with it, key main body 1 with the lock in lock gall contact and electrically connect, and the probe of the power taking in power taking contact 4 and the door lock lock gall contact and electrically connects, and electrical communication such as interior power taking probe, password storage chip 3, password testing circuit, control circuit and the power supply of lock gall and door lock, electronics pellet shot from a slingshot; And power taking contact 4 is by power-supply circuit 2 and password storage chip 3 and key main body 1 electrical communication, thereby above-mentioned total is connected and forms a loop, and control circuit can be realized carrying out password and detecting and carry out thereafter other step of unblanking being arranged at password storage chip 3 on the key main body 1 by the electric current after the conducting.Said structure is a preferred structure of the present invention, any or several mechanisms among password testing circuit of the present invention, power supply or the control circuit three also can be arranged in the key main body 1, then with door lock in other associated components electrically connect, can realize function of the present invention equally.
Above-mentionedly just preferred embodiments more of the present invention are illustrated and describe, but embodiments of the present invention are not restricted to the described embodiments,, all should belong to protection scope of the present invention as long as it reaches technique effect of the present invention with essentially identical means.
