State 5 corresponding matching of guide rail；The left and right sides that the movement carries seat 4 can be respectively equipped with protrusion, and the protrusion can pass outwards through correspondence
Sliding slot be fixedly connected with corresponding coil 6.Therefore, the sliding slot can play the role of motion guide and limit, the protrusion
The effect that the movement carries seat 4 and the coil 6 that connects is not only acted as, can be also used for preventing the coil 6 because stress can
The rotary motion that can occur.
In the application some embodiments, as shown in figure 5, being also provided with elastomer 10, the elasticity in the protrusion
Body 10 can be clamped in corresponding sliding slot, i.e., the described elastomer 10 is provided with a certain amount of pre- deformation, in the sliding slot
On be applied with the normal pressure directly proportional to deformation quantity, when having relative motion or movement tendency, the elastomer 10 and sliding slot
It just will produce frictional force on contact surface, normal pressure is bigger, and frictional force is bigger.This frictional force may make, cut off the electricity of coil 6
After stream, under the action of frictional force, the movement, which carries seat 4, can be maintained at current location, without because losing under electromagnetic force freedom
It falls.Therefore, in the application some embodiments, the elastomer 10 can play the role of kinetic damping and position is kept, to
It has saved to maintain the movement to carry electric energy of the seat 4 needed for suitable position (maintaining the optical lens 3 in suitable position).
Certainly, under the premise of can play the role of kinetic damping and position is kept, elastomer 10 can also be mounted on other positions, this Shen
Please this is not construed as limiting.
In conjunction with shown in Fig. 2 and Fig. 5, in the application some embodiments, the power source can be controlled by the optical finger print
Sensing unit 8, or be controlled by the electronic equipment internal control unit (such as the electronic equipment internal installation be used for
The processing module etc. of identifying processing fingerprint image).
In conjunction with shown in Fig. 2 and Fig. 5, in the application some embodiments, the optical finger print identification module can also include
Pedestal 1, the holder 2 can be fixedly installed on the pedestal 1, and the optical finger print sensing unit 8 can pass through 9 (example of adhesive linkage
Such as DAF glue) be bonded in the pedestal 1 upper surface middle part.
In identifying module in the optical finger print of the embodiment of the present application, the position of optical lens can be adjusted so that logical
The focal length of optical finger print identification module can be adjusted by overregulating the position of optical lens.Therefore, refer to for being configured with above-mentioned optics
For line identifies the electronic equipment of module, whether no foil layer as shown in Figure 3, or it is as shown in Figure 4 have foil layer, when
When the display screen of the contact of user's finger 300 or close electronic equipment, optical finger print identifies that module can pass through and adjusts optical lens
The position of mirror come adjust optical finger print identify module focal length, so as to collect clearly fingerprint image, therefore, the application
Embodiment can not only improve the clarity of acquired fingerprint image, can also realize hanging fingerprint recognition, to enhance
User experience.
The fingerprint identification method of the electronic equipment configured with above-mentioned optical finger print identification module is described below, in the application one
In a little embodiments, the fingerprint identification method of the electronic equipment may comprise steps of：
Receive the reflected light for carrying finger print information and according to the reflection photogenerated fingerprint image；
Confirm whether the clarity of the fingerprint image meets preset requirement；
If conditions are not met, the position of optical lens is then adjusted, until the clarity of the fingerprint image currently obtained meets institute
State preset requirement.
In the application some embodiments, when adjusting the position of the optical lens, stepwise motion side may be used
Formula adjusts, and the stepwise motion can be realized by leading to square wave current to coil.Therefore, the displacement of each stepping can the side of passing through
The amplitude and duty ratio of wave electric current determine.
In the application some exemplary embodiments, the fingerprint identification method of the electronic equipment specifically can be as in Fig. 6
Step 601~step 606 shown in.
Wherein, step 606 is not necessary to implementing the application, to prevent the machine of optical lens caused by external force possibility
Tool moves, and after whether the clarity of the confirmation fingerprint image meets preset requirement, has recorded the optics at this time
Lens present position, and as optimum position so that subsequently in optical finger print identification module initialization, it can obtain described
The current location of optical lens simultaneously matches it with the optimum position；If current location and the institute of the optical lens
Optimum position mismatch is stated, then adjusts the current location of the optical lens to the optimum position.In this way, when optical finger print is known
It, can be according to the optimum position adjust automatically optical lens recorded before this to better position, to keep away when other module reinitializes
The trouble that the focal length after initialization is resetted is exempted from.Certainly, such situation is normally only suitable for user's finger to be in direct contact electronics
The mode of the display screen of equipment carries out fingerprint recognition, and the display screen of electronic equipment does not lead to the variation (example that focal length changes
Such as not newly-increased foil layer does not remove original foil layer) the case where.When user's finger is with vacantly in the display of electronic equipment
When the mode of screen top carries out fingerprint recognition, since the overhead positions of user's finger are random, when carrying out fingerprint recognition every time
It may be there is still a need for re-focusing, in order to which clearly fingerprint image can be collected.
In the application some embodiments, the optical lens present position can be that record currently obtains to the record at this time
When the clarity of the fingerprint image obtained meets the preset requirement, the optical lens is on the optical finger print sensing unit
Projected area.In some other embodiment of the application, the record can also use the optical lens present position at this time
Other any suitable ways are (described such as when recording the clarity of the fingerprint image currently obtained and meeting the preset requirement
Optical lens relative to initial position move step number and direction, etc.).
