Abstract

The utility model is composed of a memory, a plurality of electrodes and an encapsulation piece of the memory and the electrodes. The utility model is characterized in that each electrode is an electrically conductive rod, the encapsulation piece of the memory and the electrodes is a handle (1), the part of the electrically conductive rod and the memory (2) are arranged in the handle (1), the end of the part of the electrically conductive rod is connected with the memory (2), the other part of the electrically conductive rod is extended outside the handle (1), and the electrically conductive rods are mutually insulated. The utility model is an intelligent identifying key which has the advantages of firmness and high durability, convenient carrying and multiple functions.

Description

Intelligent key

The utility model relates to key, relates in particular to intelligent recognizable key.

The mechanical key that people use always is the profile of tooth key, with a long history, use extensively, but because of its simple structure, easily copy, security performance is difficult to be guaranteed, a key can only be driven a lock in addition, and everyone usually will carry the key of a big string on one's body, and is very inconvenient, the IC-card of current trend also has as intelligent recognizable key, it is to be formed in plastic slice by electrode, memory package, and a card can be driven many locks, and security performance is good, but because of encapsulating with plastic slice, fracture easily, area is big, be not suitable for carrying, and be not suitable for children especially, so difficulty can be promoted the use of extensively.

The purpose of this utility model is to overcome above-mentioned weak point and provides and is easy to carry, and is easy to use, robust Intelligent key.

The purpose of this utility model can reach by following technical solution, by memory, several electrodes, and both packaging parts form, the utility model, electrode is a contact rod, the packaging part of memory, electrode is a handle, and in handle, and the end of this part connects with memory the part of contact rod with storage arrangement, another part of contact rod stretches out handle, mutually insulated between the contact rod.

The utility model advantage: it is sturdy and durable, and is easy to carry, and the spoonful intelligent recognizable key that can drive many locks is described in detail the utility model below in conjunction with accompanying drawing:

Accompanying drawing 1, the utility model structural representation.

Accompanying drawing 2, the A-A vertical profile enlarged drawing of Fig. 1.

Accompanying drawing 3, the utility model electrical connection graph.

Accompanying drawing 4, the circuit connection diagram of the utility model key and lock.

As shown in drawings, the utility model is by handle 1, memory 2, printed substrate 3, electrode 4, electrode 5, electrode 6, electrode 7 is formed, memory 2 is 24C01A integrated packages, electrode 4 connects

integrated package pin

1,2,3,4,7, electrode 5 connects integrated package pin 8, electrode 6 connects integrated package pin 5, electrode 7 connects integrated package pin 6,

electrode

4,6 are superimposed with each other, middle by printed substrate 3 insulation,

electrode

5,7 are superimposed with each other, the centre is also by printed substrate 3 insulation, integrated package is welded on the printed substrate 3,

electrode

4,6 with electrode 5, leave the space insulation between 7, electrode is flat, semicircle, metal conductive bar such as circle,

electrode

4,6 than

electrode

5,7 is thick so that aim at respective electrode in the lock, the metal material of electrode is brass or copper alloy, number of electrodes can be 2-8 root etc., be advisable integrated package with 4, connected electrode part and printed substrate 3 are solidificated in the plastic handle, perhaps are fixed in the metal handle, another part of every electrode stretches out handle 1, the key that will be made into so again inserts programmer, and the number that writes one group of 32 16 system is a password, promptly can be used as key.The first time, approval key K1 closed in will locking when using key, inserts key the number of key is write in the interior memory IC 3 of lock, IC3 is the 24C16 integrated package, extracts key out, disconnects K1, can open the key of this lock at any time, when this key inserts in the lockhole once more, single-chip microcomputer IC2 is whether 48R12 therefrom seeks and have and insert the identical number of key cipher, if any same password, 48R12 monolithic under-chassis 7 output signals, through R3, N1 amplifies input as relay J 1, and lock is opened.C1, C2, B1 form power circuit, and crystal XT is an oscillating circuit in the single-chip microcomputer 48R12, and frame of broken lines 1 is the lock electrical connection graph, and frame of broken lines 2 is the key electrical connection graph.

Claims

1, a kind of Intelligent key, by memory (2), several electrodes, and both packaging parts form, it is characterized in that, electrode is a contact rod, the packaging part of memory (2), electrode is handle (1), and the same memory of the part of contact rod (2) installs in handle (1), and the end of this part connects with memory, another part of contact rod stretches out handle, mutually insulated between the contact rod.

2, the described Intelligent key of claim 1 is characterized in that contact rod has 4.
