Abstract
The utility model provides a make-up mirror type car induction key, which is provided with a key control circuit, wherein the key control circuit of the induction key is arranged in a portable make-up mirror; and a high-frequency signal receiving and transmitting circuit as well as a low-frequency signal receiving circuit are arranged in the key control circuit. According to the make-up mirror type car induction key, the induction key is fixedly arranged in the make-up mirror, so that ladies can carry the key when carrying the make-up mirror; in addition, the key is a full-automatic induction key, in this way, when the car door is opened, the key can be stayed in a pocket or a bag rather than be taken out, only by pressing a button on the handle of the car door, a door lock control box can induce the key in the pocket or the bag, and then the car door is unlocked; the make-up mirror type car induction key is very convenient and rapid in use.
Description
Technical field
The utility model relates to a kind of car key, is a kind of cosmetic mirror inductive vehicle key specifically, particularly combines vanity mirror function and induction key function.
Background technology
As everyone knows, the most traditional arrangements for automotive doors key is a mechanical key.When opening the door, have only a key to insert the lock core rotation and just can open door lock.
Along with the development of radiotechnics, remote-control key has been widely used in automobile now.When you walk close to automobile, just can press the button, let the car door release.
And at present, aspect automotive applications, more novel induction type door-locking system (or being called: exempt from key system) has appearred again.When you drove, the induction key can be stayed in pocket or the bag.
But the Ms changes one's clothes and changes handbag through regular meeting, when going out, has forgotten automobile key probably.
The utility model content
The technical problem that the utility model solves is: a kind of cosmetic mirror inductive vehicle key is provided.When it was unblanked, the induction key can be stayed in pocket or the handbag, 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 adopts following technical scheme: a kind of cosmetic mirror inductive vehicle key; Said induction is provided with the key control circuit on the key, and wherein, the key control circuit of said induction key is arranged in the portable vanity mirror.
In described cosmetic mirror inductive vehicle key, in the said key control circuit, be provided with high-frequency signal transmission circuit and low frequency signal receiving circuit.
In described cosmetic mirror inductive vehicle key, the low frequency wireless signal frequency that said key control circuit receives is 120KHz～140KHz.
In described cosmetic mirror inductive vehicle key, the high-frequency wireless signals frequency that said key control circuit receives and sends is 300MHz～450MH
The described cosmetic mirror of the utility model inductive vehicle key is fixedly installed on key in the vanity mirror.When ladies are with vanity mirror, also just be with and gone up automobile key.And this key is automatically to respond to key.When driving door, do not spend by key, key can be stayed in pocket or the bag.As long as click on the door handle or near button, the door lock control box 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 the said cosmetic mirror of the utility model inductive vehicle key;
Fig. 2 is the structured flowchart of the control circuit of the said cosmetic mirror of the utility model inductive vehicle key;
Fig. 3 is the course of work explanation of the said cosmetic mirror of the utility model inductive vehicle key.
The specific embodiment
Below combine accompanying drawing that the utility model is made more detailed description with embodiment.Present embodiment only is the description to the utility model preferred forms, and the scope to the utility model does not have any restriction.
Embodiment:
As shown in Figure 1, said cosmetic mirror inductive vehicle 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 said cosmetic mirror inductive vehicle key 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 high-frequency wireless signals frequency that transmits and receives of said wireless signal transmission receiving system is 300MHz～450MHz.The low frequency wireless signal frequency that can receive is 120KHz～140KHz.
Said key control circuit is in economize on electricity (dormancy) pattern at ordinary times.Adopt the low frequency wireless signal of 120KHz～140KHz can wake key up, let the key control circuit get into mode of operation.After the key control circuit is waken up, (carry out communication like wireless signal of 300MHz～450MHz) and door lock control box with high frequency.
As shown in Figure 3, be the course of work of the described cosmetic mirror of the utility model inductive vehicle key:
1. after the button on the door handle 33 was pressed, door lock control box 32 can wake the cosmetic mirror inductive vehicle key 34 in pocket or the bag up through the radio signal of low-frequency antenna 31 emission 120KHz～140KHz.
2. after induction key 34 is waken up, use the wireless signal of 300MHz～450MHz and respond.
3. then, can be between door lock control box 32 and the induction key 34 through a series of mutual authentication processes.
4. if induction key 34 has passed through authentication, door lock control box 32 will be controlled door lock and get into released state.
5. we just can draw back car door now.
The described cosmetic mirror of the utility model inductive vehicle key will be responded to key and be fixedly installed 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.When opening the door, do not spend by key, key can be stayed in pocket or the handbag.As long as click the button on the door handle, the door lock control box just can be sensed the key in pocket or the handbag, car door release then.Use very convenient, quick.
