Abstract
The utility model provides an inductive key which is provided with a key control circuit. A hanger 2 which is arranged on the back of the inductive key 1 can be a clamp, a fixing strap or hanging fastener. By the aid of the hanger such as the clamp, the fixing strap or hanging fastener arranged on the back of the inductive key, the inductive key can be fixed onto articles such as belts or backpacks. Since the inductive key is provided with the key control circuit, a user has no need to take the key to open a door but only push a button on or close to a door handle, and then the electronic lock can induct the key on articles such as belts or backpacks to unlock. Therefore, the inductive key is quite convenient to use and rapid.
Description
Technical field
The utility model relates to a kind of electron key, is a kind of induction key specifically.
Background technology
As everyone knows, lock because relate to broad masses of the people's the person and property safety, always receives 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 receive 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.
The utility model content
The technical problem that the utility model will solve is: a kind of induction key is provided, and it unblanks not can to open the door with key or card near door lock, uses, carries all very convenient.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of induction key, and said induction is provided with the key control circuit on the key, and wherein, the back side of said induction key also is provided with suspension member.
At described induction key, be preferably, said suspension member is clip, fixed band or buckles.
At described induction key, be preferably, be provided with high-frequency signal transmission circuit and low frequency signal transmission circuit in the said key control circuit.
At described induction key, be preferably, the low frequency wireless signal frequency range that said key control circuit receives and sends is 120KHz～140KHz.
At described induction key, be preferably, the high-frequency wireless signals frequency range that said key control circuit receives and sends is 300MHz～450MHz.
The described induction key of the utility model, its back side at the induction key also is provided with like clip, fixed band or suspension member such as buckles, and can said induction key be fixed on the objects such as belt or knapsack like this; Because induction is provided with the key control circuit on the key, when opening the door, does not spend by key, as long as click on the door handle or near button; Electronic lock just can be sensed the key on the objects such as belt or knapsack; Release is then used very convenient, quick.
Description of drawings
Fig. 1 is the structural representation of the said induction key of the utility model.
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 induction key 1 is provided with the key control circuit, and also is provided with suspension member 2 at the back side of said induction key 1.Said suspension member can or buckle for clip, fixed band.Can said induction key be fixed on the objects such as belt or knapsack like this, be easy to carry, easy to use.
Preferably, be provided with high-frequency signal transmission circuit and low frequency signal transmission circuit in the said key control circuit.Wherein, the low frequency wireless signal frequency range of said key control circuit reception and transmission is 120KHz～140KHz.The high-frequency wireless signals frequency range that said key control circuit receives and sends is 300MHz～450MHz.Said 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, lets 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 lock body control circuit with high frequency.
The described induction key of the utility model, its back side at the induction key also is provided with like clip, fixed band or suspension member such as buckles, and can said induction key be fixed on the objects such as belt or knapsack like this; Because induction is provided with the key control circuit on the key, when opening the door, does not spend by key, as long as click on the door handle or near button; Electronic lock just can be sensed the key on the objects such as belt or knapsack; Release is then used very convenient, quick.
