Abstract

The utility model relates to a girdle electronic key which is engaged with an inductive electronic lock, which comprises a girdle, a leather joint, an induction coil and an IC chip, the induction coil and the IC chip are taken as a component to be pasted to a hard plastic slice in encapsulation, then the hard plastic slice is sewn to the leather joint interlayer at the side of a girdle buckle to form a non-contact induction electronic key, the lock is directly unlocked by induction without reading card, thereby the phenomena that a key card is missing or lost is avoided, and financial and medical information are capable of being deposited in favor of people entering into the digital life.

Description

The belt type electron key

The utility model belongs to the electron key with the supporting application of electronic lock, particularly a kind of electron key of belt type.

Electronic lock is opened the key of usefulness, normally used is various cards, as magnetic card, IC-card, the non-contact induction type IC-card, or encapsulated the jewelry formula card of IC sheet, as the gentle band of watch style, the keyfob that has decorative model, different key forms is brought many convenience to people's life, make electron key can one card open multi-door advantage and bring into full play, but the card form key always has forgeing or lose when changing one's clothes, if though the electronic lock of employing fingerprint or pupil recognition technology can be without key, but it is also high at present cost, be difficult to popularize and use, in order to solve the inconvenience of carrying key and to prevent forgeing and lose of electron key, designing a kind of novel electron key of wearing with oneself will go out to bring convenience to people, be of value to popularizing of electronic lock.

The purpose of this utility model is the universal use at radio frequency induction formula electronic lock, designing a kind of is the contactless electronic key of carrier with the waistband, when being gone out, people needn't carry a big string metal or a card form key specially, can open a plurality of gates that induction-type electronic door lock is installed, avoided forgeing or losing the worry of key card, the gate that often passes in and out each induction type door lock for the individual brings convenience.

The technical solution of the utility model is as follows: the electron key that radio frequency induction formula electronic lock uses is noncontact IC contactless card or claims radio frequency induction card, its core is the induction coil and the IC chip of insert in the card, this passive electronic receives the electromagnetic wave that sends on the radio circuit in the self-locking, be subjected to induction to produce electromotive force, other parts for card are powered behind the circuit rectifying and wave-filtering in blocking, memory in the IC chip is an electricity consumption readable and writable memory, when read/write operation, all need to provide the startup password, password is 32 bits, and password is set in advance by the user and is write, encryption is good, the exchanges data of radio frequency control chip and IC-card is two-way in the lock, the radio frequency control chip of at first locking is given an order and data to induction type IC card, finish control and operation to IC-card, IC-card is by the antenna of self, receiving door lock radio frequency control chip password that transmits and the password that blocks interior storage area compares, if identical then IC-card will be according to the definition of the 0th district's IC-card mode of operation configuration words, first to the 6th district's canned data in the card is sent signal with the form circulation of modulated electromagnetic wave, the radio frequency control chip of Gong locking receives, after locking the identification of MCU microprocessor analysis, start-up control and drive circuit are opened clutch, open the door by lower handle, inconsistent as the password that IC-card is received with the password password of storage in the card, then refuse to send information to the radio frequency control chip, the control that the radio frequency control chip is then accepted central microprocessor is sent to IC-card and is ceased and desisted order, make IC-card no longer launch data, enter sleep state, the chip of above-mentioned functions and coil combination are taken out the skin joint of being transplanted to waistband from card, just constituted the belt type electron key, tying up to waist can exchange induced signal induction and open the door near door lock the time, play the same tune on different musical instruments with swiping the card, but avoided drawing by key card and done the trouble of the action of swiping the card, more needn't worry forgeing and losing of key card.

Set forth concrete structure of the present utility model below in conjunction with accompanying drawing

Accompanying drawing 1 is the structure chart of induction type IC key card

1, reception/transmitting coil 2, antennal interface 3, controller 4, memory

Accompanying drawing 2 is outside drawings of belt type electron key

5, belt buckle 6, bark graft head 7 corium bands 8, induction coil and IC chip

9, spare coil and IC chip

Reception/transmitting coil 1 receives from locking the electromagnetic wave that radio frequency control circuit sends in the accompanying drawing 1, provide power supply through filter rectification to whole key card circuit, the electromagnetic wave that transmits is simultaneously given and is locked radio frequency control circuit for the identification processing, the effect of antennal interface 2 is voltage signals that the modulation and demodulation antenna receives, controller 3 is used for the legitimacy of authentication password and carries out operation to memory 4, the data message that memory 4 storage users write, whole winding and IC chip are attached on the hard plastic sheet as an assembly and cover with glued membrane again, waterproof, moistureproof, anti-extrusion, or directly be encapsulated in the hard plastic sheet, become a small-sized thin card of not being afraid of the extruding bending.

The bark graft head 6 of waistband is made with the plastic optical fibre interlayer in the middle of inserting by front and back two block leathers and is formed in the accompanying drawing 2, heart part therein, above-mentioned small-sized thin card is sewed up in the lump as sandwich, formation contains the key card of induction coil and IC chip, waistband is repeatedly pushed and is bent unavoidably in using for many years, even cause the built-in key card in skin joint that the duroplasts protection is arranged, damage also may meet accident, open circuit or chip failure appear, influence is opened the door, can add an insurance backup for this reason, second half section or nearly rear at corium band 7 imitate the skin joint sandwich way of implantation that small-sized thin card is sewed up in it, form spare coil and IC chip 9, make the belt type electron key of dual fail-safe.

Compare with other forms of electronic key card, adopt the belt type electron key of radio-frequency technique to belong to the noncontact key card, do not have wearing and tearing, magnetic stripe that does not expose and interface, need not worry to come off and breakage, reliability improves, waistband go out all tie up on one's body, avoided forgeing and losing of key, along with the realization of city " all-purpose card " networking, the waistband chip also can deposit finance and medical treatment in, identity information, the inquiry waistband is distinguished identity and retrieval personal medical information when medical treatment is rescued, and strives for that emergency time is well worth doing the body-building in residential quarters, beauty treatment, exempt to be with wallet in the consumption of supermarket, more sense is convenient, is the competent assistant who realizes digital home.

Claims

1. belt type electron key with the supporting application of induction-type electronic door lock, formed by waistband, bark graft head, induction coil and IC chip, it is characterized in that induction coil links to each other with the antennal interface of IC chip, and induction coil is pasted to be encapsulated on the hard plastic sheet and is made in bark graft head-clamp layer with sandwich form as assembly with the IC chip.
