Between region for accommodating component module, driving chip and resistance capacitor device surround the setting of fingerprint chip respectively, i.e. position respectively
In the space structure of fingerprint chip two sides, therefore, space structure is taken full advantage of, further save the inside of mobile terminal
Structure space.
As shown in Figure 3 and Figure 5, the metal ornamental ring 30 includes the interconnecting piece 31 and fixed part 32 interconnected；It is described
Interconnecting piece 31 is electrically connected with the mainboard 70；The fixed part 32 is arranged around the fingerprint chip 20.
Further, as shown in figure 5, the fixed part 32 extends to form the interconnecting piece along the 70 place plane of mainboard
31, a surface 311 of the interconnecting piece 31 is electrically connected with the mainboard 70, the 322 support institute of another surface of the interconnecting piece 31
Battery cover 60 is stated, and the fixed part 32 is abutted with the battery cover 60.
In practical application, metal ornamental ring includes the interconnecting piece and fixed part interconnected, and fixed part is flat where mainboard
Face, which extends, can form interconnecting piece, and a surface of interconnecting piece is connect with mainboard, another surface support battery cover of interconnecting piece, and solid
Determine portion and battery cover is contradicted and connected.Wherein a surface of interconnecting piece is the surface far from mainboard, and another surface of interconnecting piece is to connect
The surface of nearly mainboard.In this way, the structure of the metal ornamental ring can make battery cover stronger when assembling with metal ornamental ring.
Optionally, the connection portion and the fixed part close to the intersection of the battery cover 60 be equipped with knuckle or
Transition chamfering.
In practical application, if intersection is excessively sharp, may scratch contact or connect with metal ornamental ring it is other
The surface of component, to influence surface quality.Such as the surface of battery cover and case ring cooperation, fingerprint chip and mainboard and decoration
The surface of connection is enclosed so knuckle or transition chamfering is arranged in the fixed part and interconnecting piece intersection of case ring in the present embodiment.
And this implementation new embodiment to the specific angle of knuckle or transition chamfering without limitation, specifically can be according to mechanical normal
The setting of rule experience.
Optionally, the both ends of cover board 10 are aligned with the both ends of fingerprint chip 20.
In practical application, as shown in figure 3, the length setting of cover board and fingerprint chip is the same, when cover board and fingerprint chip are consolidated
Periodically, it should be noted that be to be aligned at the both ends of cover board with the both ends of fingerprint chip, in this way, fingerprint recognition mould group can be made
Structure is more neat.
In the utility model embodiment, as shown in figure 3, the fingerprint chip 20 is by helping weldering medium 50 and the mainboard 70
Electrical connection；Preferably, described to help weldering medium 50 for tin cream.
In practical application, fingerprint chip helps the weldering preferred tin cream of medium, in fingerprint chip by helping weldering medium and mainboard to weld
Tin paste layer is filled between mainboard, tin paste layer is that one kind helps weldering substance, can play the role of good welding, make fingerprint chip with
The connection of mainboard is stronger.What certain those skilled in the art can also select other materials helps weldering medium, the utility model
Embodiment to help weldering medium without limitation.
In the utility model embodiment, as shown in figure 3, the interconnecting piece 31 passes through 70 electricity of conducting medium 40 and the mainboard
Connection；Optionally, the conducting medium 40 is conductive glue or conductive double sided adhesive tape.
In practical application, the stationary plane of metal ornamental ring is connect by conducting medium with mainboard, and the conductive of the present embodiment is situated between
It is of fine quality to select conductive glue or conductive double sided adhesive tape, in this way, electrostatic can be introduced directly into the ground terminal GND of mainboard by case ring, have
Release electrostatic is imitated, to avoid influence of the electrostatic to fingerprint chip performance.Certain those skilled in the art can also select other
The conducting medium of material, the utility model embodiment to conducting medium without limitation.
Optionally, the thickness of the fingerprint chip are as follows: 0.06mm~0.7mm；The thickness of the cover board are as follows: 0.1mm~
0.56mm。
It in practical application, is fixedly connected between cover board and fingerprint chip by bond medium, when the thickness of cover board is less than
0.1mm, when the thickness of fingerprint chip is less than 0.06mm, it is difficult to guarantee that fingerprint chip packing-body has enough mechanical strengths, from
And it is easily damaged fingerprint chip packing-body；When the thickness of cover board is greater than 0.56mm, and the thickness of fingerprint chip is greater than 0.7mm,
It will lead to the oversized of fingerprint recognition chip packing-body and significantly increase its space occupied, electronics is greatly improved and sets
Standby thickness.Therefore, the thickness of fingerprint chip and cover board is needed to be arranged according to the requirement of actual mobile terminal product,
Such as mobile terminal requirement is lightening, then the thickness of cover board can be as thin as 0.1mm, fingerprint recognition chip can be such that it is meeting by force
The thickness of fingerprint chip can be as thin as 0.06mm while degree requires.
In practical application, when fingerprint recognition mould group and battery cover cooperation, there is certain section between the cooperation plane of the two
Potential difference, if the integral thickness of fingerprint recognition is too thin, fingerprint recognition mould group can be fallen in too much, will affect the appearance of mobile terminal,
And the experience effect of user is bad, and therefore, the thickness of fingerprint recognition mould group cannot be too thin, in order to improve the experience effect of user
And usage comfort, this implementation new embodiment can do the thickness of the skirt thickness of metal ornamental ring and fingerprint chip suitably
Thickening processing.
To sum up, mobile terminal described in the utility model embodiment has the advantage that
Firstly, since the present embodiment by fingerprint chip, cover board and metal ornamental ring from mobile terminal interior successively
Stacking is assemblied on the mainboard of mobile terminal, is no longer one independent compared with the fingerprint recognition mould group of existing mobile terminal
It is whole, save the internal structural space of mobile terminal；Also, it is also applied for modularization, standardization, General design；
Secondly as fingerprint chip is set up directly on mainboard by the present embodiment, compared with existing fingerprint recognition mould group,
Connector, FPC plate and stiffening plate are eliminated, in practical applications, the structure of fingerprint recognition mould group is not only simplified, also reduces
Assembly technology process, to reduce design cost and manufacturing cost；And the performance of fingerprint recognition is more preferable；
Again, it is directly connect with mainboard due to the metal ornamental ring of the present embodiment by conducting medium, in this way, electrostatic can be with
It is introduced directly into the ground terminal GND of mainboard by case ring, is released effectively electrostatic, to avoid electrostatic to the shadow of fingerprint chip performance
It rings；Also, after engaging battery cover with case ring, the area of space between battery cover and mainboard is for accommodating component group
Part makes full use of space structure, to further save the internal structural space of mobile terminal.
It is apparent to those skilled in the art that for convenience and simplicity of description, the system of foregoing description,
The specific work process of device and unit, can refer to corresponding processes in the foregoing method embodiment, and details are not described herein.
