Abstract
The utility model provides a cosmetic mirror type induction key provided with a key control circuit, which is disposed in a portable cosmetic mirror. The key control circuit comprises a high frequency signal receiving and transmitting circuit and a low frequency signal receiving and transmitting circuit. The cosmetic mirror type induction key employs a design of fixing a key in the cosmetic mirror, thereby guaranteeing that a woman takes the key when she takes the cosmetic mirror. The cosmetic mirror type induction key needs not to be taken out from a pocket or a bag when being used for opening a door, can be sensed by an electronic lock when a button on or near a door knob is pressed, and thus realizes unlocking, thereby being convenient and rapid.
Description
Technical field
The utility model relates to a kind of electron key, is a kind of induction key specifically, particularly vanity mirror function and induction key function is combined.
Background technology
As everyone knows, lock because relate to broad masses of the people's the person and property safety, always is subjected to the Chinese government and the people's extensive concern as a kind of anti-theft tool.And the door lock with automatically controlled structure is widely used owing to the convenience of its use.
Because electronic lock can have more than one hundred million times password combination, thereby has higher confidentiality and application life than mechanical lock, more and more be subjected to the attention of user and manufacturer.Magnetic card type or noncontact reading-card type door lock reach its maturity and popularize.
But present noncontact reading-card type electronic lock all still needs a key card near door lock when unblanking.Be placed in the bag and work as card, can't find for the moment, perhaps when both hands were held article, it was just very inconvenient to open the door.
And when going out, key card in the necessary extra band.And the Ms often changes one's clothes or change bag, forgets probably or loses key card.
The utility model content
The technical problem that the utility model solves is: the induction key that a kind of mirror of making up is provided.It does not need to unblank key or the close door lock of card can be opened the door, and uses very convenient.And the control circuit of induction key is arranged in the vanity mirror, has portable vanity mirror function and induction key function simultaneously.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions: a kind of cosmetic mirror induction key, described induction is provided with the key control circuit on the key, wherein, the key control circuit of described induction key is arranged in the portable vanity mirror.
In described cosmetic mirror induction key, in the described key control circuit, be provided with high-frequency signal transmission circuit and low frequency signal receiving circuit.
In described cosmetic mirror induction key, the low frequency wireless signal frequency that described key control circuit receives is 120KHz～140KHz.
In described cosmetic mirror induction key, the high-frequency wireless signals frequency that described key control circuit receives and sends is 300MHz～450MH
Cosmetic mirror induction key described in the utility model is fixedly installed on key in the vanity mirror.When ladies are with vanity mirror, also just be with and gone up key.And this key is automatically to respond to key.Do not spend when opening the door by key, when opening the door, key can be stayed in pocket or the bag.As long as click on the door handle or near button, electronic lock just can be sensed the key in pocket or the bag, release then.Use very convenient, quick.
Description of drawings
Fig. 1 is the structural representation of cosmetic mirror induction key described in the utility model;
Fig. 2 is the structured flowchart of the control circuit of cosmetic mirror induction key described in the utility model;
Fig. 3 is the course of work explanation of cosmetic mirror induction key described in the utility model.
The specific embodiment
Below for a more detailed description to the utility model in conjunction with the accompanying drawings with embodiment.Present embodiment only is the description to the utility model preferred forms, scope of the present utility model is not had any restriction.
Embodiment:
As shown in Figure 1, described cosmetic mirror induction key comprises the key control circuit 200 of vanity mirror body 100 and induction key, and the key control circuit 200 of wherein responding to key is fixed in the vanity mirror.Be easy to carry like this, easy to use.
As shown in Figure 2, the control circuit of described cosmetic mirror induction key comprises and is provided with high-frequency signal transmission circuit and low frequency signal receiving circuit.Comprise the LED display circuit 23, high-frequency signal transmission circuit 24 and the low-frequency antenna receiving circuit 25 that link to each other with control module 22 specifically, and power supply 26, button cell can be adopted.Wherein, high-frequency signal transmission circuit 24 can connect high frequency antenna 28 again, and low-frequency antenna receiving circuit 25 can connect low-frequency antenna 27 again.To strengthen the receiving ability of its wireless signal.
Preferably, the described wireless signal transmission receiving system high-frequency wireless signals frequency of launching is 300MHz～450MHz.The low frequency wireless signal frequency that can receive is 120KHz～140KHz.
Described key control circuit is in economize on electricity (dormancy) pattern at ordinary times, adopts the low frequency wireless signal of 120KHz～140KHz can wake key up, allows the key control circuit enter mode of operation.After the key control circuit is waken up, (carry out communication as wireless signal of 300MHz～450MHz) and lock body control circuit with high frequency.
As shown in Figure 3, the operating principle of automatically responding to door lock for described cosmetic mirror described in the utility model is:
1. after the button on the lock body 31 33 was pressed, lock body control circuit 32 can be launched the radio signal of 120KHz～140KHz, woke the key 34 in pocket or the bag up.
2. after key 34 was waken up, key control circuit 35 was used the wireless signal of 300MHz～450MHz and is responded.
3. then, can be between lock body 31 and the key 34 through a series of mutual authentication processes.
4. if key 34 has passed through authentication, lock body 31 will enter released state.
Now we just can swing handle, open the door.
Cosmetic mirror induction key described in the utility model is fixedly installed on key in the vanity mirror.When ladies are with vanity mirror, also just be with and gone up key.And this key is automatically to respond to key.Do not spend when opening the door by key, when opening the door, key can be stayed in pocket or the bag.As long as click on the door handle or near button, electronic lock just can be sensed the key in pocket or the bag, release then.Use very convenient, quick.
