Detailed ways

The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are not to be construed

In the present disclosure, the orientation words used, such as "left, right, inside, and outside", generally refer to left, right, inside, and outside, as indicated in the accompanying drawings, "clockwise". "Counterclockwise" generally refers to the clockwise and counterclockwise directions indicated in the corresponding figures.

As shown in FIG. 1A to FIG. 2B, the present disclosure provides a fingerprint recognition device 10 including a motor 11, a transmission mechanism 12, and a fingerprint recognition module 13, wherein the motor 11 is used to drive fingerprint recognition through the transmission mechanism 12. The module rotates between a first position in which the operating surface 131 of the fingerprint recognition module 13 is hidden, and a second position in which the operating surface 131 of the fingerprint recognition module 13 is exposed.

According to the fingerprint identification device, when the user needs to perform a fingerprint input operation, the motor 11 rotates forward, and the fingerprint recognition module 13 is driven by the transmission mechanism 12 to rotate from the first position to the second position, when the fingerprint recognition module 13 rotates to the second position. The motor 11 stops rotating. At this time, the operation surface 131 of the fingerprint recognition module 13 is exposed, so that the user performs a fingerprint input operation on the operation surface; when the user does not need to perform a fingerprint input operation, the motor 11 is reversed and driven by the transmission mechanism 12. The fingerprint recognition module 13 rotates from the second position to the first position. When the fingerprint recognition module 13 is rotated to the first position, the motor 11 stops rotating. At this time, the operation surface 133 of the fingerprint recognition module 13 is hidden, thereby avoiding the operation surface 131 thereof. The protection of the fingerprint recognition module 13 can be achieved by prolonged exposure to the external environment.

It should be noted that, in the embodiment of the present disclosure, the operation surface of the fingerprint identification module refers to the side of the fingerprint recognition module that is provided with the fingerprint recognition sensor, and the user inputs a fingerprint on the operation surface, and the fingerprint recognition sensor can acquire the fingerprint information of the user. .

In one embodiment, the motor 11 can be a stepper motor or a servo motor. If the motor 11 is a stepping motor or a servo motor, the rotation angle of the motor shaft 111 of the motor can be more accurately controlled, and then the transmission mechanism 12 can drive the fingerprint recognition module 13 to rotate the set angle and then stop, thereby implementing the fingerprint recognition module 13 Positioning.

Further, in another embodiment, the motor 11 can be a conventional motor. In this case, in order to accurately control the rotation angle of the fingerprint recognition module 13, a first sensor and a second sensor may be added. Wherein, the first sensor and the second sensor may be selected by a travel switch or a micro switch. When the motor 11 drives the fingerprint recognition module 13 to rotate to the first position through the transmission mechanism 12, the first sensor is touched and sends a signal to the control module, the control module controls the motor 11 to be powered off, and the motor 11 stops rotating, so that the fingerprint recognition module 13 Positioned in the first position; when the motor 11 drives the fingerprint recognition module 13 to the second position through the transmission mechanism 12, the second sensor is touched and sends a signal to the control module, the control module controls the motor 11 to be powered off, and the motor 11 stops rotating. The fingerprint identification module 13 is positioned in the second position.

In order to prevent the fingerprint recognition module 13 from being rotated after being rotated into position, it is further possible to add the electromagnetic clutch 14 to the fingerprint recognition device 10. Wherein, as shown in FIG. 3, the electromagnetic clutch is mounted on the motor shaft 111 of the motor 11, and the fingerprint recognition module 13 is held in the first position or the second position by the locking of the motor shaft 111 by the electromagnetic clutch.

Specifically, when the motor 11 is powered off, the electromagnetic clutch is engaged to lock the motor shaft 111 at this time, so that the transmission mechanism 12 cannot move, so that the fingerprint recognition module 13 is kept in the first position or the second position and cannot be moved; when the motor 11 Upon energization, the electromagnetic clutch disengages to release the motor shaft 111 such that the transmission mechanism 12 can be moved by the motor 11 to drive the fingerprint recognition module 13 to rotate between the first position and the second position.

Alternatively, the electromagnetic clutch may include a clutch housing 141, an electromagnet, a translational friction plate 145 and a rotating friction plate 146, an outer race 147, and an inner race 148.

The inner race 148 is slidably coupled to the motor shaft 111 by a spline, and the rotary friction plate 146 is disposed on the inner race 148 to be rotatable by the motor shaft 111. The outer race 147 is slidably coupled to the inner wall of the clutch housing 141 by a spline, and the translational friction plate 145 is disposed on the outer race 147 to be able to translate in the axial direction of the motor shaft 111. The fixed iron core 142 and the movable iron core 143 may be formed in an annular structure, and the moving iron core 143 is sleeved on the outside of the motor shaft 111, and the fixed iron core 142 is sleeved on the outside of the moving iron core 143 to make the fingerprint identification device The structure is more compact. When the electromagnet loses power, the magnetic attraction between the fixed iron core 142 and the movable iron core 143 disappears, the movable iron core 143 moves to the right under the action of the driving spring 144, and pushes the translational friction plate 145 and the rotating friction plate 146 to combine. The friction between the two causes the motor shaft 111 to be locked; when the electromagnet is energized, a magnetic attraction force is generated between the fixed iron core 142 and the movable iron core 143, so that the movable iron core 143 is reset while compressing the drive spring 144. The translational friction plate 145 and the rotary friction plate 146 are separated, and the friction between them disappears to release the locking of the motor shaft 111.

When the fingerprint recognition module 13 needs to be rotated, the motor 11 is powered, and the fingerprint recognition module 13 is driven to rotate by the electromagnetic clutch and the transmission mechanism 12; when the fingerprint recognition module 13 is rotated to the second position or the first position, the motor 11 is de-energized. The electromagnetic clutch is de-energized to lock the motor shaft 111 of the motor 11, thereby maintaining the fingerprint recognition module 13 in the first position or the second position.
