Abstract

The utility model relates to a fingerprint collecting window for a fingerprint lock, which comprises a window and a wicket, wherein, the window is a hole arranged on a casing body. The utility model is characterized in that the wicket is a bit larger that the window, and the wicket is in rotary connection with the casing body of a fingerprint lock and is positioned at the inner side of the window; a power switch is fixed on the casing body of the fingerprint lock, and a switch drive structure cooperating with the power switch is arranged on the wicket; an elastic reset mechanism is arranged between the wicket and the casing body, and the wicket veils the window and cuts off the power when the wicket is in a reset state. The utility model has the advantages that the situation that a fingerprint collecting sensor is directly exposed to the outside severe environment, and the invasions of dust and water mist can be reduced; meanwhile, the power consumption of the fingerprint lock can be effectively reduced, and the reaction of the power switch is sensitive.

Description

A kind of fingerprint collecting window of Fingerprint Lock

Technical field

The utility model relates to a kind of Fingerprint Lock, but is specifically related to a kind of fingerprint collecting window construction that is used to protect fingerprint sensor and double as Fingerprint Lock power supply on the Fingerprint Lock of being located at.

Background technology

Raising along with fingerprint identification technology, Fingerprint Lock has begun to apply, in all kinds of Fingerprint Lock, all need the fingerprint collecting sensor, the user will point by on the fingerprint collecting sensor, allow Fingerprint Lock collection, identification, outside the fingerprint collecting sensor is directly exposed to, be vulnerable to the invasion and attack of dust, water smoke; On the other hand, for reducing the power consumption of Fingerprint Lock, power switch need be set, existing Fingerprint Lock, generally a press button is set in the fingerprint collecting beneath window, behind the Push switch, power connection, can distinguish fingerprint, behind suitable time-delay, power supply cuts off automatically, when reusing, Push switch energising again, though it is this structure has played the effect of economize on electricity, has increased an action when user operates, convenient inadequately, particularly when being used for occasion double as recording equipments such as library, conference room, more can cause integral body to log on the prolongation of time.

In view of this, someone has developed a kind of sliding window structure, in the window inboard slideway is set, is provided with slide in the slideway, pass slide with finger, acquisition window is opened, when slide put in place, its top was provided with power switch, connected power supply, automatically distinguish, differentiate, this structure can be avoided on the one hand outside the fingerprint collecting sensor is directly exposed to, simultaneously, change an action of passing slide into switch power supply with by two actions pointing, but sliding door structure is complicated, poor reliability, must put in place during slippage and could connect power supply, influence speed, simultaneously, when finger is passed slide, there is sub-fraction to be blocked inevitably, the identification of possible effect characteristics point by slide.

Summary of the invention

The utility model purpose provides a kind of fingerprint collecting window of Fingerprint Lock, both can play a protective role to the fingerprint collecting sensor, but double as Fingerprint Lock power switch again, its structure should simple and reliable, handled easily simultaneously.

For achieving the above object, the technical solution adopted in the utility model is: a kind of fingerprint collecting window of Fingerprint Lock, comprise window, window, the hole of described window on housing, offering, described window is more bigger than window, be rotationally connected with the Fingerprint Lock housing, be positioned at the window inboard, be fixed with power switch on the Fingerprint Lock housing, window is provided with the switch drive structure that cooperates with it, be provided with flexible restoring organ between window and housing, window covers window and cuts off the electricity supply when resetting attitude.

In the technique scheme, described " flexible restoring organ " can be so that window be in the attitude that resets when not being subjected to external force, and at this moment, window is positioned at the window inboard and covers window, and simultaneously, the switch drive structure on the window makes power switch be in dissengaged positions; The fingerprint collecting sensor of Fingerprint Lock is positioned at the window limit, uses the finger push window, and window rotates, finger enters in the window, just in time be positioned at fingerprint collecting sensor place, at this moment, because the rotation of window, power switch is opened, by the fingerprint collecting sensor acquisition and distinguish fingerprint, correct as fingerprint, Fingerprint Lock will be opened, when finger left, window was closed under the flexible restoring organ effect automatically.

In the technique scheme, the torsion spring of described flexible restoring organ in rotating shaft, being provided with, described power switch is a microswitch, the switch drive structure on the described window is a driving lever.

Wherein, described microswitch can be installed on the face vertical with window, and the button of microswitch top is provided with oblique catch, and driving lever is positioned at a side of window and contacts with catch; Described microswitch also can be installed on the face parallel with window, and the one side of described driving lever contacts with the cooperation of the button of microswitch.

In the technique scheme, described flexible restoring organ is a spring, and described switch drive structure is the cam mechanism that is arranged in the rotating shaft, and the installation position of power switch cooperates with cam mechanism.

In the technique scheme, being used for a kind of more convenient structure that fingerprint locks is that described window arranges that vertically the rotating shaft of window is positioned at the window top.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

1. because the utility model is provided with window and window structure at fingerprint collecting sensor place, avoid the fingerprint collecting sensor to be directly exposed in the outside adverse circumstances, can reduce the invasion and attack of dust, water smoke;

2. the utility model is provided with the switch drive structure on window, cooperate with microswitch, can reduce the electric quantity consumption of Fingerprint Lock effectively, whole lock is not in the pass electricity condition when having fingerprint collecting at ordinary times, when having only finger to stretch into the fingerprint collecting window, just power connection is worked, this has the meaning of particular importance for the Fingerprint Lock with dry cell power supply;

3. the utility model window is rotational structure, and is simple in structure, only rotating shaft need be set and torsion spring can be realized, simultaneously, its power switch and window are in contact condition at ordinary times, thereby are quick on the draw, the problem that can not connect when can slide switch not in place.
