Abstract

The utility model discloses an electronic key, comprising a universal serial bus (USB) unlock interface, wherein a password input key is arranged on the key; a controller for receiving a password signal input on the key is arranged inside the key; the controller is electrically connected with the USB unlock interface; the key also comprises an induction chip. The electronic key disclosed by the utility model has a password protecting function; the electronic key cannot be unlocked even if the key falls into hands of a lawless person if the lawless person does not know the password, so that the safety is strong. The electronic key includes the induction chip; the induction chip can be matched with a door magnetic inductor; an unlock step is added. Thus, the safety is further improved.

Description

A kind of electron key

Technical field

The utility model relates to a kind of key, relates to specifically a kind of electron key.

Background technology

The tradition key is stolen joining easily, has potential safety hazard, although electron key is difficult to join steathily, once lose or stolen and robbed, will is utilized by the lawless person and unblank easily.

The utility model content

Technical problem to be solved in the utility model just is to provide a kind of electron key of high safety.

The utility model adopts following technical scheme:

A kind of electron key, comprise the USB interface of unblanking, and the Password Input button is being arranged on the key, and the controller that receives the code signal that above-mentioned button inputs is arranged in key, and this controller and the USB interface of unblanking is electrically connected to, and also includes induction chip in key.

Further, the display that shows input password figure place is being arranged on the key.

Further, described password figure place is four.

The beneficial effects of the utility model are:

Electron key disclosed in the utility model, with cipher protection function, even fall into lawless person's hand, if do not know password, also can't unblank, high safety.With induction chip, can match with the door magnetic inductor, increase again the step of unblanking together, further increase security.

The accompanying drawing explanation

Fig. 1 is the connection diagram of the utility model embodiment 1 disclosed electron key.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

Embodiment 1, as shown in Figure 1, the present embodiment discloses a kind of electron key, comprise the USB interface 1 of unblanking,Password Input button 2 is being arranged on the key, the controller that receives the code signal that above-mentioned button inputs is arranged in key, and this controller and the USB interface of unblanking is electrically connected to, and also includes induction chip in key.The display that shows input password figure place is being arranged on the key.Described password figure place is four.

When using the disclosed electronic key unlocking of the present embodiment, at first the USB interface of unblanking is inserted to the corresponding interface on electronic lock, then by Password Input key-press input password, this code signal is received by controller, if password is correct, controller is inputted unlock instruction by the USB interface of unblanking to electronic lock, completes and unblanks; If the password mistake, controller is inputted alarm command by the USB interface of unblanking to electronic lock, unblanks unsuccessfully.

Unblank if can complete, also need to pull up electron key again, make it to contact with the door magnetic inductor, if the induction chip in key is complementary with the door magnetic inductor, discharge door magnetic, door is opened, otherwise does not discharge a magnetic, still can't open the door.

The disclosed electron key of the present embodiment, with cipher protection function, even fall into lawless person's hand, if do not know password, also can't unblank, high safety.With induction chip, can match with the door magnetic inductor, increase again the step of unblanking together, further increase security.

Claims (3)

1. an electron key, comprise the USB interface of unblanking, it is characterized in that: the Password Input button is being arranged on the key, the controller that receives the code signal that above-mentioned button inputs is arranged in key, this controller and the USB interface of unblanking is electrically connected to, and also includes induction chip in key.

2. electron key according to claim 1, is characterized in that: the display that shows input password figure place is being arranged on the key.

3. electron key according to claim 2, it is characterized in that: described password figure place is four.
