Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein ad initio
Same or similar element or the element with same or like function are represented to same or similar label eventually.Below by ginseng
The embodiment for examining Description of Drawings is exemplary, it is intended to for explaining this utility model, and it is not intended that to this utility model
Restriction.
Below with reference to the accompanying drawings the fingerprint recognition module and mobile terminal of this utility model embodiment are described.
Fig. 1 is the structural representation of the fingerprint recognition module according to this utility model one embodiment.As shown in figure 1, should
Fingerprint recognition module includes：Fingerprint recognition chip 110 and optics cardiotachometer 120.
Wherein, the surface of fingerprint recognition chip 110 is provided with an induction region 111, and induction region 111 is used for gathering user
The finger print data of input.
Optics cardiotachometer 120 includes light source 121 and optical receiver 122.
Wherein, light source 121 can be arranged on inside fingerprint recognition chip 110, it is also possible to be arranged on fingerprint recognition chip 110
Outside, for lighting at the finger contact induction region 111 of user.
Optical receiver 122 is arranged in fingerprint recognition chip 110, for receiving the optical signal of finger reflection, and according to light
The heart rate of signal detection user.
In embodiment of the present utility model, as shown in Fig. 2 light source 121 includes multiple luminescence units 1211, it is multiple luminous
Unit 1211 is arranged on the inside of fingerprint recognition chip 110, and multiple luminescence units 1211 are set around the outside of induction region 111

It is embedded in induction region 111.
Further, as shown in figure 3, multiple receiving units 1221 can be with integrated distribution in the center of induction region 111
Domain；As shown in figure 4, multiple receiving units 1221 can also be evenly distributed in induction region 111.
In one embodiment of the present utility model, multiple receiving units 1221 are evenly distributed in induction region 111, can
It is distributed with predetermined interval with being each receiving unit 1221.Wherein, predetermined interval can include lateral separation and longitudinally spaced, i.e.,
The lateral separation of the laterally adjacent receiving unit 1221 of any two is equal, the longitudinally adjacent receiving unit 1221 of any two
It is longitudinally spaced equal.
Specifically, when the finger of user is touched on induction region 111, light source 121 lights, and light handles finger refraction
Afterwards, the optical receiver 122 being integrated in fingerprint recognition chip 110 is received, as the heartbeat of user can be made in blood vessel
There is fluctuation in blood, can interfere with the refraction of light, and the optical signal that optical receiver 122 is received can be subject to fluctuations in blood in finger
Impact and produce fluctuation.Optical receiver 122 is sampled to these optical signals, and optical signal is become corresponding data signal,
Carry out process calculating to data signal, and then obtain the fluctuations in blood frequency of user's finger, i.e. heart rate.
Further, if the heart rate for obtaining is in 50～200 beats/min, can be determined that the source of fingerprint is live body,
I.e. heart rate is normal.
In embodiment of the present utility model, if the finger print data matching of user input, and heart rate would be normal, then judge to use
The authentication success at family.
If it is understood that being detected fingerprint from non-living body, the optical signal that optical receiver 122 is received will not
Generation is shaken, i.e., be definite value to the result after optical signal prosessing calculating, it is impossible to react heart fluctuation.
Thus, integrated optical receiver 122, even light source in the fingerprint recognition chip 110 in fingerprint recognition module
121, the heart rate detecting function of optics cardiotachometer not only can be realized, and answering for this body structure of fingerprint recognition module will not be increased
Polygamy is not also high to the volume requirement of fingerprint recognition module.
Further, when the fingerprint recognition module is arranged in the terminal, it is easier to realize, and terminal will not be answered
Structure design bring considerable influence.And then can make that the integrally-built complexity of mobile terminal is low, the production test time is shorter,
Ensure that production yield and production cost.

Covering 140.
Wherein, the wrapping fingerprint recognition of encapsulating structure 130 chip 110 is arranged, and covering 140 is arranged on encapsulating structure 130
Upper surface.
It should be noted that due to using the mode of photoinduction to detect the heart rate of user, so fingerprint recognition module
Covering 140 need certain light transmission, i.e. covering 140 and be made up of light transmissive material.
In embodiment of the present utility model, covering 140 can include but is not limited to glass or sapphire.
In one embodiment of the present utility model, the encapsulating structure 130 for wrapping 110 setting of fingerprint recognition chip can be
It is made up of transparent material, such as transparent plastics etc..
The fingerprint recognition module of this utility model embodiment, is identified to finger print data by fingerprint recognition chip, and
The heart rate of user is obtained by the optical receiver being arranged in fingerprint recognition chip, and then can determine that the source of finger print data is
It is no for live body, thereby, it is possible to improve the reliability of fingerprint recognition, it is ensured that the safety of authentication, and the fingerprint recognition mould
Group structure complexity is low, beneficial to improving product yield, reduces cost.
Further, the utility model proposes a kind of mobile terminal, including the fingerprint of this utility model above-described embodiment
Identification module.
In embodiment of the present utility model, the mobile terminal includes but is not limited to smart mobile phone, flat board, portable computing
Machine or Fingerprint Lock etc..
