The utility model content

The purpose of this utility model with regard to be to provide in order to address the above problem a kind of when contacting with electronic lock with the electron key of delivery of electrical energy to electronic lock.

The utility model is achieved through the following technical solutions above-mentioned purpose:

Electron key described in the utility model comprises key turning handle, electrode, shell, battery, have the circuit board of at least one key subregion and be installed on CPU on the described circuit board, described key turning handle is used for inserting in the lockhole of electronic lock, the inner of described key turning handle is fixedly connected with an end of described shell, described electrode is installed on the outer end of described key turning handle and is used for being electrically connected with electronic lock, be electrically connected between described electrode and the described circuit board, described battery, circuit board and CPU all place in the described housing.

By installing electrodes on the key turning handle, can realize when electron key contacts with electronic lock the delivery of electrical energy of the electron key purpose to electronic lock, like this, electron key and electronic lock are all by the powered battery in the electron key, realize data transmission, check and the open and close lock function, under the prerequisite that satisfies accurately control, realize little power consumption electric drive function.

For the opening ways and the opening device that keep traditional mechanical lock and strengthen security, the outer end of described key turning handle be equipped with for the locating piece of the supporting projection of electronic lock lockhole.During use, the groove in locating piece and the electronic lock lockhole is chimeric, in the situation that electronic lock is opened the lock core by the rotating electron lock, realizes unblanking or shutting mechanically.

Further, described shell is provided with the button that is forced off lock signal be used to providing, and the inner of described button is connected with described circuit board.Button can be realized the function that shuts fast.

Further, also be provided with the pilot lamp that is used to indicate the electronic lock switch state on the described shell, described pilot lamp is connected with described circuit board.

As preferably, described shell is waterproof case.

The beneficial effects of the utility model are:

Electron key described in the utility model and electronic lock are supported the use, the electrode that utilizes electron key with delivery of electrical energy to electronic lock, thereby make electronic lock get electric work, can guarantee the normal operation of electronic lock, can power supply be installed in electronic lock again, reduce power consumption, be conducive to energy-conserving and environment-protective; Adopt the electronic identity verification mode between electron key and the electronic lock, mutual opening rate is almost nil, and is safe; Circuit board can be preserved many group electronic locks numberings and key pair, realizes one the function of key operated a plurality of electronic locks, and is easy to use; Because this electron key kept mechanical open and close lock construction, and do not need battery with the supporting electronic lock of this electron key, so can easily traditional mechanical lock be adapted as electronic lock or electromechanical lock, safe class promotes greatly.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Such as Fig. 1, Fig. 2 and shown in Figure 3, electron key described in the utility model comprises key turning handle 1, electrode 7, waterproof case 10, battery 9, circuit board 5 and the CPU 6 that is installed on the circuit board 5 with at least one key subregion, key turning handle 1 is used for inserting in the lockhole of electronic lock (not shown), the outer end of key turning handle 1 be equipped with for the locating piece 11 of the supporting projection of electronic lock lockhole, the inner of key turning handle 1 is fixedly connected with an end of waterproof case 10, electrode 7 is installed on the outer end of key turning handle 1 and is used for being electrically connected with electronic lock, be electrically connected battery 9 between electrode 7 and the circuit board 5, circuit board 5 and CPU 6 all place in the waterproof case 10; Waterproof case 10 is provided be used to providing the button 4 that is forced off lock signal and the first pilot lamp 2, the second pilot lamp 3 that is used to indicate the electronic lock switch state, and the inner of button 4, the first pilot lamp 2, the second pilot lamp 3 are connected with circuit board 5 respectively.Battery 9 adopts button cell or other energy storage device such as rechargeable super capacitor.Also show the electric capacity 8 that is installed on the circuit board 5 among Fig. 3.

Circuit board 5 has at least one key subregion, the key subregion is preserved with the form of semiconductor permanent memory, the content of this subregion can not read by the miscellaneous equipment beyond the electron key body, can only delete, revise, increase, open the high security function of a plurality of electronic locks and electronic lock to reach an electron key.A key subregion comprises unique number and the unblocking key of an electronic lock at least, and this partition information is being authorized by writing later on by the electron key manager.CPU 6 adopts the single-chip microcomputer of low-power consumption, Multiple Type on the market can satisfy, and such as 51 series, PIC series, ARM is serial, MSP is serial etc., its effect is the cipher key identity authentication of finishing with electronic lock cylinder, managing keys comprises that key adds, deletes, revises, searches simultaneously.

Such as Fig. 1, Fig. 2 and shown in Figure 3, principle of work and the course of work of electron key described in the utility model are as follows:

After electron key correctly inserts the electronic lock cylinder (not shown), power supply on the electron key is transferred to the electronic lock cylinder power supply by electrode 7, and electronic lock cylinder begins to start, after initialization is finished, the connection of electronic lock cylinder by linking to each other with electron key interior circuit board 5, both sides begin both-way communication.

At first electron key and electronic lock cylinder all obtain the other side's unique number, electron key begins to search its corresponding unblocking key in the key subregion, if do not find, then can not open corresponding electronic lock, show this electron key therewith electronic lock cylinder be non-matching relation.Electron key begins to carry out authentication by the unblocking key of correspondence and electronic lock, after the identity for the treatment of electron key is passed through by the electronic lock cylinder authentication, electronic lock cylinder is opened unlocking mechanism, this moment, staff was by rotating electron key (consistent with traditional mechanical lock), by key turning handle 1 and locating piece 11 drive electronic lock cylinders unlatching lock bodies.If the authentication failure then can not the unlocking electronic lock core.

After the opened lock, if lock is in the closed position, need the electron key hand rotation to the electronic lock cylinder initial position, require the closed unlocking mechanism of electronic lock cylinder by the button semi-finals system on the electron key, or treat electronic lock cylinder auto-closing unlocking mechanism, behind the first pilot lamp 2 of electron key or the closed unlocking mechanism of the second pilot lamp 3 indication electronic lock cylinder successes, extract electron key, No. one time switch lock is finished.

If it is too fast that electron key is extracted when locking, electronic lock cylinder does not have the normally closed unlocking mechanism, and the first pilot lamp 2 or the second pilot lamp 3 be flash for prompting always.
