When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The terms to which the present invention relates will be explained first:
a gyro sensor: an apparatus capable of accurately determining the orientation of a moving object includes a simple, easy-to-use, free-space movement and gesture-based positioning and control system;
the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1, the present invention provides an electronic device 10, which includes a device body 100, a fingerprint identification assembly 200, a gyro sensor 300, an anti-shake structure 400 and a controller 500.
The device body 100 may be a mobile phone, a tablet computer, or other electronic devices including fingerprint recognition function.
The position of the fingerprint identification module 200 on the device body 100 can be selected according to actual needs, and the present application is not limited thereto. For example, the fingerprint recognition assembly 200 may be disposed at the bottom of the front of the electronic device or at the side of the electronic device in view of convenience of operation and aesthetic appearance of the electronic device.
The size of the fingerprint collection physical key 210 of the fingerprint identification component 200 may be selected according to actual needs, and is not limited in this application.
Fig. 2 is a schematic view of a mounting position of a fingerprint identification component, fig. 3 is another schematic view of the mounting position of the fingerprint identification component, referring to fig. 2, taking an electronic device as a mobile phone as an example, the fingerprint identification component is arranged at the bottom of the front face of the mobile phone, referring to fig. 3, the fingerprint identification component is arranged at the side face of the mobile phone.
The gyro sensor 300 is used to detect the offset amount and the offset angle of the geometric center point of the fingerprint recognition assembly 200. It should be noted that the gyro sensor 300 is provided with a program for detecting the fingerprint recognition assembly 200 before use. The gyro sensor 300 uses the geometric center of the fingerprint recognition device 200 as a reference point, and when the fingerprint recognition device 200 is pressed and slightly shaken, the gyro sensor 300 can detect the offset and the offset angle of the geometric center. The offset refers to a moving distance of the geometric center store from an original position point to a new position point, and the offset angle may also be understood as an offset angle of the new position point to the original position point.
The anti-shake structure 400 is mechanically coupled to the fingerprint recognition assembly 200 for moving the fingerprint recognition assembly 200. It is understood that the anti-shake structure 400 may be a stretching assembly that pulls the geometric center point of the fingerprint recognition assembly 200 back to the initial position when the fingerprint recognition assembly 200 is displaced. For example, the stretching assembly may include a tether and a transmitter, and the tether may be mechanically coupled to the fingerprint identification assembly 200 and the motor. When the fingerprint identification component 200 is deviated, the transmitter drives the rope to move the fingerprint identification component 200, so that the geometric center point of the fingerprint identification component 200 is restored to the initial position.
The controller 500 is configured to control the anti-shake structure 400 to operate according to the offset amount and the offset angle, and control the fingerprint recognition assembly 200 to move by the operation of the anti-shake structure 400 so as to compensate for the offset of the geometric center of the fingerprint recognition assembly 200. It is understood that the controller 500 is communicatively connected to the gyro sensor 300, and the controller 500 may convert the offset and the offset angle collected by the gyro sensor 300 into electrical signals, and further process and analyze the electrical signals to determine the compensation displacement and the compensation angle of the geometric center point of the fingerprint recognition assembly 200 according to the offset and the offset angle. The compensation displacement is used to compensate for the offset of the geometric center of the fingerprint identification assembly 200, and the compensation angle is used to compensate for the offset angle of the geometric center of the fingerprint identification assembly 200. That is, when the staff is pressing fingerprint identification subassembly 200 and is carrying out fingerprint identification, fingerprint identification subassembly 200 produces slight shake because of pressure to the geometric centre point of fingerprint identification subassembly 200 also can produce the skew, just can't ensure the normal of fingerprint and type this moment. And controller 500 indirect control anti-shake structure 400 removes fingerprint identification subassembly 200, alright reset in order to make the geometric centre point of fingerprint identification subassembly 200 to solve the unable problem of normally logging in of fingerprint. In one embodiment, the controller 500 may be a central processor.
The electronic device 10 provided by the present invention includes a device body 100, a fingerprint recognition assembly 200, a gyro sensor 300, an anti-shake structure 400, and a controller 500. The fingerprint identification component 200 includes a fingerprint capture physical key 210 for capturing user fingerprint information when a user finger presses the fingerprint capture physical key 210. The gyro sensor 300 is used to detect the offset amount and the offset angle of the geometric center point of the fingerprint recognition assembly 200. The controller 500 is configured to control the anti-shake structure 400 to operate according to the offset amount and the offset angle, and control the geometric center of the fingerprint identification assembly 200 to move by the operation of the anti-shake structure 400, so as to compensate for the offset of the geometric center of the fingerprint identification assembly 200. Therefore, when the fingerprint identification assembly 200 is pressed to shake, causing the geometric center point to deviate from the initial position point, the controller 500 can control the geometric center point of the fingerprint identification assembly 200 to return to the initial position point through the anti-shake structure 400, thereby ensuring normal input of fingerprints. Therefore, the electronic device 10 provided by the invention can solve the problem that the conventional scheme cannot ensure normal input of the fingerprint if the fingerprint identification component is deviated when the mobile terminal is used for fingerprint identification.
In one embodiment of the present application, the anti-shake structure 400 includes at least one magnetic spring 410, and at least one electromagnet 420 fixedly connected to the at least one magnetic spring 410.
At least one magnetic spring 410 and fingerprint identification subassembly 200 fixed connection, the length, model, the material, the spring inner distance etc. of magnetic spring 410 all can select according to actual need, and this application does not do the restriction. The magnetic spring 410 is fixedly connected to the fingerprint identification module 200, and the fixed connection mode can be selected according to actual needs, which is not limited in this application. It should be noted that the attachment of the magnetic spring 410 to the fingerprint identification assembly 200 does not affect the function of the fingerprint identification assembly 200.
Each electromagnet 420 is used to control the compression or extension of one magnetic spring. It will be appreciated that the magnetic spring 410 is fixedly attached to the fingerprint recognition assembly 200 at one end and to the electromagnet 420 at the other end. When the magnetism of the electromagnet 420 is increased, the magnetic spring 410 fixedly coupled to the electromagnet 420 having the increased magnetism may cause the fingerprint recognition assembly 200 to approach the electromagnet 420 having the increased magnetism, thereby completing the movement of the fingerprint recognition assembly 200.
The controller 500 is configured to control the magnitude of the magnetism of the electromagnet 420 according to the offset amount and the offset angle. For example, the electromagnet 420 may be disposed at the right side of the fingerprint recognition device 200, and when the geometric center point of the fingerprint recognition device 200 is moved to the left with respect to the initial position point, the controller 500 controls the magnetism of the electromagnet 420 to be increased, so that the fingerprint recognition device 200 is moved to the right. At this time, the offset amount and the offset angle of the geometric center point of the fingerprint recognition assembly 200 are detected by the gyro sensor 300 and transmitted to the controller 500.
Specifically, the controller 500 calculates the compensation displacement and the compensation angle required for the geometric center point reset according to the offset and the offset angle of the geometric center point of the fingerprint identification device 200. Further, the controller 500 selects a target electromagnet according to the compensation displacement and the compensation angle, and increases or decreases the magnetism of the target electromagnet so that the geometric center point moves closer to or farther from the target electromagnetThe iron moves. As shown in fig. 1, when the geometric center point of the fingerprint identification device 200 moves along the direction of the arrow, i.e., the upper right corner, the offset distance is the straight line distance from the initial position point of the geometric center point, i.e., point a, to the new position point, i.e., point B, along the direction of the arrow. The geometric center point is placed on a two-dimensional plane, if the coordinates of the point A are defined as (X1, Y1), the coordinates of the point B are defined as (X2, Y2), and the straight-line distance is defined as L, then
When the offset angle is defined as a, then
At this time, the controller 500 may select electromagnets located at the lower end and the left end of the fingerprint recognition assembly 200 as target electromagnets. At this time, the controller 500 determines the magnetic magnitude of the target electromagnet according to the linear distance from the point a to the point B and the included angle between the point a and the point B.
For example, the corresponding relationship between the linear distance from the point a to the point B, the offset angle, and the magnetic magnitude is predefined, and then the corresponding magnetic values at different distances and offset angles are obtained according to the corresponding relationship. The magnetic properties of the target electromagnet may attract the magnetic spring coupled to the target electromagnet to stretch, thereby restoring the position of the geometric center point of the fingerprint identification assembly 200 from point B to point a. Furthermore, the magnitude of the current applied to the target electromagnet is determined according to the magnetic magnitude of the target electromagnet, and the magnetic magnitude of the electromagnet is controlled through the magnitude of the current.
In a possible implementation manner of the present application, the current applied to the target electromagnet may also be directly obtained according to the linear distance from the point a to the point B and the included angle between the point a and the point B, for example, a corresponding relationship between the linear distance from the point a to the point B, the offset angle, and the current magnitude is predefined, and then the corresponding current values at different distances and offset angles are obtained according to the corresponding relationship.
In one embodiment of the present application, the anti-shake structure 400 includes two magnetic springs 410 and two electromagnets 420, and the two magnetic springs 410 are disposed on two opposite sides of the fingerprint identification assembly 200. For example, the magnetic springs 410 may be disposed on the left and right sides of the fingerprint recognition device 200, or on the upper and lower sides of the magnetic springs 410.

The corresponding operation can comprise fingerprint unlocking, volume increasing or decreasing and electronic equipment switching. The flexible circuit board 230 may be disposed under both the fingerprint collection physical key 210 and the pressure sensor 220, or a portion of the flexible circuit board 230 may be disposed between the fingerprint collection physical key 210 and the pressure sensor 220, that is, the fingerprint collection physical key 210 and the pressure sensor 220 are stacked to form a combined key.
