It is appreciated that basic ring 21 is located in centre bore 213 formed with centre bore 213, support edge 23.Centre bore 213 can be with
In right cylinder shape, in other words, the medial surface 212 of basic ring 21 is linearly, in order to which fingerprint identification module 30 rapidly loads center
In hole 213.
The material that centre bore 213 and support edge 23 can be removed on part by way of machining is formed, can also
Formed by modes such as castings.
In order to ensure the intensity of case ring 20, it is preferred that the material of case ring 20 is metal, such as stainless steel material, from
And meet the intensity requirement of case ring 20, also with corrosion resistance, improve the service life of case ring 20.Certainly, case ring 20
The other materials such as plastics can be used to be made.
In some embodiments, medial surface 212 of the support edge 23 perpendicular to basic ring 21.
In this way, support edge 23 is easily formed, the manufacture cost of basic ring 21 can be reduced.In addition, when manufacture cover plate assembly 100
When, support edge 23 is horizontally situated, and the medial surface 212 of basic ring 21 is located at vertical position so that the finger coordinated with support edge 23
The face of line identification module 30 is horizontal plane, can so simplify the structure for the fingerprint identification module 30 being supported on support edge 23.
In some embodiments, basic ring 21 includes bottom surface 214, the lower surface of support edge 23 and the bottom surface 214 of basic ring 21
Concordantly.
In the basic ring 21 of equal height, such as arrangement above, larger accommodating space can be formed in basic ring 21, to ensure
Fingerprint identification module 30 can be housed in basic ring 21.
In other words, in the case where the thickness of fingerprint identification module 30 is constant, the height of basic ring 21 is smaller, so as to drop
The thickness of low cover plate assembly 100, and then offer design basis can be thinned for the thickness of electronic device 200.
Fig. 7 and Fig. 8 is referred to, in some embodiments, support edge 23 is connected formed with the centre bore 213 with basic ring 21
Avoid holes 231.

Cabling layout.For example, flexible PCB 60 can be to pass through avoid holes 231 to connect with fingerprint identification module 30.
In some embodiments, 231 rounded rectangle of avoid holes, the long side side wall of avoid holes 231 are offered and avoided
The escape groove 232 that hole 231 connects, escape groove 232 extend along the length direction of avoid holes 231.
Such as shown in Fig. 6, after flexible PCB 60 is connected with fingerprint identification module 30, first prolong to the direction of escape groove 232
Stretch, then bend detour.Therefore, escape groove 232 can prevent flexible PCB 60 and the side wall of avoid holes 231 from interfering,
Be conducive to flexible PCB 60 to connect up.
Referring to Fig. 5, in some embodiments, fingerprint identification module 30 includes packaging body 31 and fingerprint recognition core
Piece 32.
Specifically, when user carries out the operation of unlocked by fingerprint electronic device 200, finger can be placed on and fingerprint recognition core
32 corresponding position of piece.The signal of fingerprint recognition chip 32, to gather the fingerprint pattern of identification user, will be used through packaging body 31
The fingerprint pattern at family is matched with the fingerprint pattern to prestore, if successful match, unlocks electronic device 200.
It is appreciated that the surface of fingerprint recognition chip 32 towards the finger of user is provided with sensor pixel array, with collection
The fingerprint pattern of user.Packaging body 31, which encapsulates fingerprint recognition chip 32, can reduce sensor pixel array when gathering fingerprint pattern
Influenced be subject to other interference signals, to improve the accuracy rate of identification.
In some embodiments, the top surface of fingerprint identification module 30 is provided with cover plate 33.For example, cover plate 33 passes through
Colloid is fixed on the top surface of fingerprint identification module 30.
When carrying out fingerprint recognition operation, finger can be pressed against in cover plate 33 user.Cover plate 33 can be with tamper seal
It is without damage to fill body 31, to improve the reliability of fingerprint identification module 30.
Cover plate 33 is touched due to being often subject to, the material that cover plate 33 can be used hardness higher is made, such as with
On the sapphire material that refers to.
In some embodiments, the shape of the top surface of the form and dimension of cover plate 33 and fingerprint identification module 30 and big
Small cooperation.
For example, the shape of the top surface of fingerprint identification module 30 is in oval, the shape of cover plate 33 is also in oval.Covering
Area of the area of plate 33 slightly larger than the top surface of fingerprint identification module 30.Therefore, fingerprint recognition can be completely covered in cover plate 33
Module 30.
Please be refering to Fig. 5 and Fig. 8, in some embodiments, support chip 40 includes the periphery of self installation through hole 13 to logical
The supporting part 41 of the center extension in hole, case ring 20 are arranged in installation through-hole 13 and are fixedly connected with supporting part 41.For example, dress
Decorative circle 20 is fixedly connected with supporting part 41 by bonding mode.And for example, case ring 20 and supporting part 41 be by welding
It is fixedly connected.
In this way, since support chip 40 is fixedly connected with cover board 10, and case ring 20 is fixedly connected with support chip 40, so that
Can prevent case ring 20 from being moved relative to cover board 10, be conducive to user press case ring 20 in fingerprint identification module 30 with into
Row fingerprint recognition operates.
In some embodiments, support chip 40 includes the fixed part 42 for being fixed on the lower surface 12 of cover board 10, fixed part
42 are fixedly connected with supporting part 41.
In other words, the periphery of installation through-hole 13 is first extended to outside the periphery of 40 self installation through hole 13 of support chip, then from peace
The periphery for filling through hole 13 extends to the center of installation through-hole 13.
The lower surface 12 that support chip 40 is fixed on cover board 10 is conducive to support chip 40 and is fixedly connected with cover board 10, for example, branch
Blade 40 can be fixed on the lower surface 12 of cover board 10 by way of bonding.
In some embodiments, the fixed part 42 of support chip 40 is set around installation through-hole 13, and supporting part 41 is around installation
The circumferentially extending of through hole 13.In this way, the area that supporting part 41 is contacted with case ring 20 is larger, is conducive to case ring 20 and stablizes twelve Earthly Branches
Support is on supporting part 41.
In some embodiments, supporting part 41 forms the protrusion 43 that oriented case ring 20 protrudes, and case ring 20 is resisted against
In protrusion 43.
