Represented left and right, inside and outside in respective drawings, " clockwise, counterclockwise " typically refers to represented suitable in respective drawings
Clockwise, counter clockwise direction.
As shown in Figure 1A to Fig. 2 B, present disclose provides a kind of fingerprint identification device, which includes electricity
Machine 11, protective cover 13 and cleaning unit 30 for blocking fingerprint identification module 20, wherein cleaning unit 30 is for cleaning fingerprint
Identification module 20；Motor 11 is for driving protective cover 13 to rotate between open and closed positions, in the closed position,
Protective cover 13 shelters from fingerprint identification module 20；In the open position, fingerprint identification module 20 is exposed.
In another embodiment, fingerprint identification device 10 can also include transmission mechanism 12, and motor 11 can pass through biography
Motivation structure 12 drives protective cover 13 to rotate.
According to the fingerprint identification device 10, when user needs to carry out fingerprint input operation using fingerprint identification module 20,
Motor 11 rotates forward, and drives protective cover 13 to rotate from closed position to open position by transmission mechanism 12, when protective cover 13 rotates
To after open position, motor 11 stops operating, and fingerprint identification module 20 is exposed at this time, so that user carries out fingerprint input behaviour
Make, and can needed to fingerprint identification module after protective cover 13 moves to open position by the way that cleaning unit 30 is arranged
20 spray water to fingerprint identification module 20 when being cleaned, to remove the dust adhered on fingerprint identification module 20, to guarantee to refer to
Line identification module 20 is clean, improves the sensitivity of its fingerprint recognition；And when user does not need using fingerprint identification module 20, electricity
Machine reversion drives protective cover 13 to rotate from open position to closed position, when protective cover 13 rotates to pass by transmission mechanism 12
When closed position, motor 11 stops operating, and fingerprint identification module 20 is sheltered from and be isolated with external environment by protective cover 13 at this time, from
And realize the protection to fingerprint identification module 20.
In one embodiment, motor 11 can be stepper motor or servo motor.If motor 11 is stepper motor or watches
Motor is taken, then can precisely control the rotational angle of the motor shaft 111 of motor, and then can be driven by transmission mechanism 12 anti-
Stop after the angle of the rotation setting of protecting cover 13, realizes the positioning of protective cover 13.
In addition, in another embodiment, motor 11 can be ordinary motor.In this case, in order to accurately right
13 corner of protective cover is controlled, and first sensor and second sensor can also be added.Wherein, first sensor and second
