The fingerprint module 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 4.

As shown in fig. 1-3, the fingerprint module 100 according to the embodiment of the present invention includes: fingerprint identification key 1, reinforcement 2, fingerprint FPC subassembly 3 and support 4, fingerprint identification key 1 is used for discerning the fingerprint.

Be provided with reinforcement 2 on fingerprint identification key 1, reinforcement 2 includes: a reinforcing plate 21 and a reinforcing side sheet 22. The stiffening plate 21 of the stiffening member 2 is attached to and fixedly connected with the back of the fingerprint identification key 1 (for example, the stiffening plate 21 is connected with the back of the fingerprint identification key 1 through a cold welding technology, so that the stability of connection between the stiffening plate 21 and the fingerprint identification key 1 can be ensured, the deformation of the fingerprint identification key 1 caused by thermal stress can be avoided, and the structural strength of the fingerprint identification key 1 can be enhanced by the stiffening plate 21, and the service life of the fingerprint identification key 1 can be prolonged by some schemes even bonding or plastic connection of the stiffening plate 21 and the fingerprint identification key 1.

The edge of the reinforcing plate 21 is connected with reinforcing side pieces 22, and the reinforcing side pieces 22 are at least two pieces and are arranged on at least two sides of the reinforcing plate 21. Therefore, the structural rigidity of the reinforcing part 2 can be enhanced, the supporting effect on other parts can be improved, and the effect of increasing the strength of the module can be achieved.

As shown in fig. 2 and 3, the fingerprint FPC assembly 3 has: the fingerprint identification key comprises an interaction section 31, an extension section 32 and a connector 33, wherein the interaction section 31 is connected between the fingerprint identification key 1 and the reinforcing plate 21, the interaction section 31 is electrically connected with the fingerprint identification key 1, and one end of the interaction section 31 is connected with the connector 33 through the extension section 32.

It will be appreciated that the fingerprint FPC assembly 3 is a flexible printed circuit board with a connector 33. After the fingerprint identification key 1 obtains the fingerprint information, the collected fingerprint information is transmitted to the central control structure of the electronic device 1000 through the fingerprint FPC component 3.

Wherein, mutual section 31, extension section 32 are fingerprint FPC subassembly 3's flexible portion, adopt flexible mutual section 31 to connect between fingerprint identification key 1 and stiffening plate 21, and not only mutual section 31 is thin makes fingerprint module 100 can not be too thick, and mutual section 31 can hug closely on fingerprint identification key 1 and stiffening plate 21 moreover, further reduces thickness on the one hand like this, and on the other hand can let stiffening plate 21 can transmit the holding power to fingerprint identification key 1 easily.
